In the preparation of this volume the Editor's object has not been to add unnecessarily to the number of encyclopaedias already existing, but to present to the profession a working text-book which shall be closely limited to, while completely covering, the field of pediatrics. To make such a book useful to the practitioner, who must too often read as he runs, and to the student, who of necessity is unable to devote his study hours to one branch of medical science, but must divide them between many general and special subjects, it seems essential that certain conditions should be closely adhered to. These are — first, careful condensation, without omission, that the whole subject may be embraced between the covers of one readily handled volume ; second, limitation of the subject-matter to such practical points as Etiology, Symptomatology, Diagnosis, and Treatment including Feeding, Hygiene, Therapeutics and the Prevention of Disease, while avoid- ing, so far as possible, the insertion of references to journals or authorities, of more interest to those engaged in research than to those in active practice; third, the selection of a large staff of collaborators from the most important medical centres of our country, to secure for each subject the care of the authority best fitted to portray it, to give the work broadness and stamp it with a national, rather than a sectional, imprint ; fourth, so to time the pub- lication that, without undue haste, each article contributed should have the same freshness, and the book as a whole be thoroughly abreast with the rapid advance which is constantly made in this branch of our profession ; finally, the addition of chapters upon certain subjects which, though usually treated specially and separately, constantly come under the notice of those Avho work with, or study, the ills of childhood, such as diseases of the eye, the ear, the skin, the nose and throat, and the anus and rectum ; circumcision, tracheotomy, intubation, vesical calculus, venereal disease and allied subjects. These conditions we have endeavored to fulfil. iii IV PREFA CE. In conclusion, the Editor desires to thank individually the collaborators he has been so very fortunate in securing, and to tender them, in advance, the greater share of whatever credit may attend the venture. His thanks are also due to Dr. Thompson S. Westcott for his most efficient and interested assistance. LOUIS STARR. 1818 rittenhouse square. Philadelphia. LIST OF CONTRIBUTORS. SAMUEL S.

THE CLINICAL INVESTIGATION OF DISEASE AND THE GENERAL MANAGEMENT OF CHILDREN. By LOUIS STARR, M. D., Philadelphia. I. The Clinical Investigation of Disease. Early life may be divided into two periods — namely, infancy and child- hood. Infancy is the time elapsing between birth and the complete eruption of the milk teeth, an event that transpires about the end of the second year of life ; childhood extends from this age to the development of puberty, about the age of thirteen or fifteen years. Of the diseases that may occur during these periods a few are peculiar to the time of life, or are "children's diseases" proper; others, while identical in class with the ordinary affections of adult and mature years, are variously modified in symptoms and course by conditions inherent to early age ; but in all the clinical investigation is beset with difficulties which the student must be prepared to overcome. Thus, the absence of speech in the infant deprives us of the important assistance afforded by correctly described subjective symp- toms, and renders it necessary to look to the mother or nurse for the history of an illness. In older children the case is little better, since with them words are not prompted by sufiicient knowledge to be of great service. Further, the wilfulness, dislikes, fear, and agitation of the child are impediments which must be overcome before a satisfactory examination can be made, and which will often tax the skill and patience of the physician to the utmost in the over- coming. Another source of difficulty lies in the activity of growth and devel- opment in infants, which renders them liable to be affected by slight causes, and makes disease sudden in its attack, short in its course, and intense in its symptoms. The rapid development of the nervous system especially leads to confusion. The nerves bind every portion of the frame in a sympathy so close that an affection of a single part may cause marked general disturbance, and local symptoms are often reflected, directing attention to organs very distant from those really diseased. Finally, the extreme excitability of the nervous system of healthy children often causes a trifling illness to assume an aspect of the greatest gravity ; while, on the contrary, the depression of nervous sensi- 1 2 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. bility that attends chronic wasting diseases so obscures the symptoms that a dangerous intercurrent aifection may appear trifling or remain altogether latent. On the other hand, to offset these difiiculties, disease in the child is usually uncomplicated, rarely has its course and symptoms modified by tissue lesions the result of previous affections, and never by vicious habits, such as the abuse of stimulants and narcotics, or by mental overwork and nerve-strain. The confusing element of misstated subjective symptoms is also absent, while cor- rect diagnosis is greatly aided by the facility with which physical examination of the whole body may be practised. In conducting the investigation it is well to proceed in three regular stages, as follows : 1st. Questioning the attendants ; 2d. Inspecting the child ; 3d. Physical examination. 1. Questioning tine Attendants. When the patient is under eight or ten years of age, the only way of obtaining a knowledge of the previous history and of what may occur between visits is carefully to question the mother or nurse. The account must be patiently elicited, and credited with due reference to the narrator's intelligence. It is well never entirely to discredit a statement without good reason, for many women, though weak and foolish in other respects, are excellent observers when their powers are guided by affection. Besides, being thoroughly acquainted with their children's habits and dispositions, they will often detect deviations from health that the physician might overlook entirely. This part of the examination, particularly when the acquaintance and good-will of the child have not previously been obtained, should, if possible, be made before entering the sick-room. As there are certain points about which it is always necessary to be informed, the adoption of a definite order of questioning is advisable. The family history as far back as the parents should first be ascertained, inquiry being chiefly directed to the detection of chronic maladies and trans- missible diseases, as tuberculosis and syphilis. If any deaths have occurred, their causation should be investigated ; and an inquiry into the occurrence, or the reverse, of previous stillbirths is often important. Then an outline of the child's life from birth up to the date of the illness in question must be obtained. This should include the following items : The manner of feeding during infancy — whether at the breast or from a bottle, and if the latter, the com- position of the food employed ; the date of commencement and the regularity of dentition ; the general state of health in regard to strength or weakness and liability to illness ; the time of occurrence and the nature of any prominent attack of illness, especially of the eruptive fevers ; whether vaccination has been performed or no ; the hygienic surroundings — for instance, the healthful- ness of the locality of residence, the sort of house and room occupied, and the character of the clothing and food. In older children, if at school, the time devoted to study, and if at labor, the nature and the hours of work. After this it is necessary to fix the time the attack in hand began. The occurrence of some striking symptom, as convulsions or violent vomiting, often establishes this point beyond a doubt ; but when there is any uncertainty the best plan is to question back, day by day, until a time is reached at which the child was perfectly well, and to date the onset from this period. The most common of the general indications of commencing illness are disturbed sleep and irritability of temper. CLINICAL INVESTIGATION OF DISEASE. 3 The next step is to learn the mode of attack and the symptoms and course of the disease prior to the first visit. The questions now must be general, never leading. They must be sufficiently exhaustive to touch upon all the •functions of the body, and when a trail is started it must be patiently followed to the end. Alterations in sleep, bodily strength, surface temperature, appe- tite, digestion, urine elimination, respiration, and so on, must be sought for, and the account of such deviations from the normal state as vomiting, diarrhoea, or cough will suggest further questions, as well as point out the path to be followed in the future examination. This portion of the investigation is closed by an inquiry into the treatment that may have been already adopted. 2. Inspecting the Child. When the eye and ear of the physician are trained to their work, valuable information can be obtained by simply looking at an ill child and listening to its cry or spoken words. Even while the child is lying asleep or sitting quietly in the nurse's lap many facts may be learned ; but this portion of the exami- nation is never complete without an inspection of the naked body. The points thus ascertained consist in alterations in the expression of the face, in decubitus, in the appearances of the body, and so on, and may be designated the features of disease. The relative position of the observer and patient during inspection is of importance. If possible, the former should stand with his back to, and the latter be so placed that his face is toward, a window or lamp. The light must never be strong enough to dazzle when the countenance is the object of inspection, as this causes distortion of the features. For convenience, the features of disease will be studied under different headings ; and since to appreciate them it is necessary to have a knowledge of the healthy aspect, both the normal and abnormal appearances will be described. Face. — The face of a healthy sleeping child wears an expression of perfect repose. The eyelids are completely closed, the lips slightly parted, and while a faint sound of regular breathing may be heard, there is no perceptible move- ment of the nostrils. Incomplete closure of the lids, with more or less exposure of the whites of the eyes, is noted when sleep is rendered unsound by moderate pain and during the course of all acute and chronic diseases, particularly when they assume a grave type. Twitching of the lids heralds the approach of a convulsion, and at such times, too, there is often oscillation of the eyeballs or squinting. A marked smile, due to contraction of the muscles about the mouth, signifies abdominal pain or colic, and pursing out of the lips and chew- ing motions of the jaw, gastro-intestinal irritation. Dilatation of the alse.nasi, with or without noisy breathing, points to embarrassed respiration, the result of extensive bronchial catarrh, pneumonia, or pleurisy with effusion. When awake and passive the healthy infant's face has a look of wondering observation of whatever is going on about it. As age advances the expression of intelligence increases, and every one is familiar with the bright, round, happy face of perfect childhood, so indicative of careless contentment and so mobile in response to emotions. The picture is altered by the onset of any illness, the change being in pro- portion to the severity of the attack. An expression of anxiety or of suffering appears, or the features become pinched and lines are seen about the eyes and mouth. Pain most of all sets its mark upon the countenance, and by noting the feature affected it is often possible to fix the seat of serious disease. Thus, contraction of the brows denotes pain in the head ; sharpness of the nostrils, 4 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. pain in the chest ; and a drawing of the upper lip, pain in the abdomen. As a rule, the upper third of the face is modified in expression in affections of the brain, the middle third in diseases of the chest, and the lower third in lesions of the abdominal viscera. Puffiness of the eyelids and a fulness of the bridge of the nose indicate dropsy, and should direct attention to the kidneys. When there is a tuberculous tendency the face is often oval, the features delicate, and the expression intelligent ; the hair fine and silky ; the skin smooth and trans- parent ; the temporal veins visible ; the eyelashes long and curving, the irides large and deep-colored, and the sclerotics pearly white or bluish ; finally, a growth of fine hair is often noticeable on tlie temples and in front of the ears. On the contrary, the face may be round and heavy ; the complexion doughy ; the upper lip swollen ; the nostrils wide and the alse of the nose thick ; the eyelids swollen and reddened at their edges ; the hair coarse ; and the lymphatic glands of the neck enlarged. A marked disfigurement of the face may indicate one of several diseases, according to its character. For example, broadness or complete flatness of the bridge of the nose is significant of constitutional syphilis. A large, square head and projecting forehead, with a fiice of natural size or smaller, show that the child has suffered from rickets. An immense globular head, overhanging forehead, and diminutive face, with eyeballs projected downward and irides almost concealed by the lower lids, are pathognomonic signs of chronic hydrocephalus. Decubitus. — The complete repose depicted on the countenance of a healthy sleeping child is shown also by the posture of the body. The head lies easy on the pillow ; the trunk rests on the side, slightly inclined backward ; the limbs assume various but always most graceful attitudes, and no movement is observable but the gentle rise and fall of the abdomen in respiration. In the waking state the child, after early infancy, is rarely still. The movements of the arms, at first awkward, soon become full of purpose as he reaches to handle and examine various objects about him. The legs are idle longer, though these, too, soon begin to be moved about with method, feeling the ground in pi'eparation for creeping and walking. With the onset of disease the scene changes. In acute attacks attended with pain sleep is no longer restful. The infant is content only when rocked, fondled, or "walked" in the nurse's arms. The older child tosses about uneasily in bed, or demands a constant change from the bed to the lap. During the waking hours the movements are purposeless, quick, and impatient, the position is constantly shifted, and frequent whining complaints are made. As a contrast to this condition of jactitation, at the beginning of the specific fevers children often lie quiet and drowsy for hours. In chronic affections attended with debility the movements become slow and languid, and in stupor and coma there are perfect stillness and immobility. There are certain positions and gestures which have especial significance. Sleeping with the head thrown back and the mouth open is a frequent accom- paniment of chronic enlargement of the tonsils. A tendency to "sleep high " — that is, with the head and shoulders elevated by the pillow — indicates impaired pulmonary or cardiac function. So, too, does an upright position in the nurse's arms, with the chest against her breast and the head hanging over her shoul- der — a posture assumed by young children. " Sleeping cool " — namely, rest- ing only after all the bed-clothing has been kicked off — is an early symptom of rickets. The position termed en chien de fusil is a symptom of the advanced stages of cerebral disease, especially tubercular meningitis. The child lies upon one side, with the head stretched far back, the arms pressed close to the CLINICAL INVESTIGATION OF DISEASE. 5 sides and folded across the chest, the thighs drawn up toward the abdomen, the legs flexed on the thighs, and the feet crossed. Restless movements of the head or boring of the head into the pillow also point to cerebral disease. A retained position, as on the back or one side, together with short, quick breath- ing, points to some inflammatory change in the respiratory or abdominal organs. Persistent lying on the face is an evidence of photophobia. Of gestures, the frequent carrying of the hand to the head, ear, or mouth indicates headache, earache, or the pain of dentition respectively, and constant rubbing of the nose is a feature of gastro-intestinal irritation. If the thumbs be drawn into the palms of the hands and the fingers tightly clasped over them, or if the toes be strongly flexed or extended, a convulsion may be expected. The presence of clonic contractions of the muscles, with unconsciousness, indicates, of course, a convulsion ; while irregular, badly co-ordinated, jerky movements — consciousness being retained — attend chorea. In infants the existence of colic is shown by repeated extension and retrac- tion of the legs, clenching of the hands into fists, flexion and extension of the forearms, and a writhing movement of the trunk. The fact of one limb remaining passive while the others are actively moved about naturally sug- gests motor paralysis. The Skin. — In the new-born infant the color of the skin varies from a deep to a light shade of red. After the lapse of a week this redness fades away, leaving the sui'face yellowish-white, and in a fortnight the skin assumes its typical appearance. Allowing for natural variations in complexion, the skin of a healthy child is beautifully white, transparent, and velvety. The cheeks, palms of the hands, and soles of the feet have a delicate pink color, and the general surface is rosy in a warm atmosphere, marbled Avith faint blue spots or lines in a cool one. As age advances the coloring becomes more pro- nounced, and until the completion of childhood the complexion is much fresher than in adult life. Lividity of the eyelids and lips is a sign of imperfect aeration of the blood and points to pulmonary or cardiac disease. Marked blueness of the whole face is a symptom of morbus cceruleus, and indicates a congenital malforma- tion of the heart. On the other hand, a faint purple tint of the eyelids and around the mouth shows weak circulation merely, or, more frequently, deranged digestion. A decided yellow hue of the skin and conjunctivae is seen in jaun- dice ; an earthy tinge of the face in chronic intestinal diseases ; a waxy pal- lor in renal diseases ; and paleness in any affection attended with exhaustion. Brownish-yellow discoloration of the forehead is significant of inherited syphi- lis ; a bright, circumscribed flush on one or both cheeks, of inflammation of the lungs or pleura or of gastro-intestinal catarrh, according to its occurrence with or without an elevated temperature. In addition to the cutaneous lesions of the eruptive fevers, each having its special characteristics, an eruption of herpetic vesicles on the lips may be men- tioned as present both in pneumonia and in malarial fevers. Slight want of proper aeration of the blood is shown by blueness of the finger-nails ; a greater degree, by cyanosis of the whole hand. Deformity of the nails is a symptom of syphilis ; clubbing of the finger-tips, of chronic lung disease ; and redness, swelling, and suppuration about the nails, of struma. The dropsy of scarlatinal nephritis causes a pufiiness and cushiony appear- ance of the dorsum of the hands. Often, too, in this condition, the finger-ends are glossy as if smeared with oil, and there is an exfoliation of the epidermis about the nails. The last two symptoms frequently serve to confirm a retro- spective diagnosis of scarlet fever. 6 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Mode of Drinking. — By watching an infant taking the breast or bottle some knowledge can be obtained of the condition both of the mouth and throat and of the respiratory organs. If there be any soreness of the mouth, the nipple is held only for a moment, and then dropped with a cry of pain. When the throat is affected, deglutition is performed in a gulping manner, an expression of pain passes over the face, and no more efforts are made than required to satisfy the first pangs of hunger. Under similar circumstances older children drink little and refuse solid food entirely. An infant suffering from the oppression of pneu- monia or severe bronchitis seizes the nipple with avidity, swallows quickly several times, and then pauses for breath. In older patients the act of drink- ing, Avhicli should be continuous, is interrupted in the same way. If the finger be put into the mouth of a healthy baby, it will be vigor- ously sucked for some little time. The diminution of the act of suction dur- ing a severe illness is a sign of danger ; its re-establishment a good omen. In conditions of stupor and coma it is noticeably absent. The Cry. — Crying is the chief, if not the only, means that the young infant possesses of indicating his displeasure, discomfort, or suffering. Even long after the powers of speech have been developed, the cry continues to be the main channel of complaint. It may be accepted as a rule that a healthy child rarely cries. Of course, some acute pain, as from a fall or accident or blow, Avill cause crying in the most healthy child, but the storm is quickly over. Incessant, unappeasable crying is due to one of two causes — namely, earache or hunger — and the distinction may readily be made by putting the child to the breast or offering a properly-prepared bottle. The hydrencephalic cry, denoting pain in the head, is a sudden, sharp, very loud, and paroxysmal shriek. Crving: during an attack of coughino; or for a brief time afterward, and attended with distortion of the features, indicates pneumonia. In acute pleuritis the cry also accompanies the cough, but it is produced too by move- ments of the body and by pressure on the affected side. It is louder, indica- tive of greater suffering, and sometimes most difficult to check. Intestinal pain causes crying just before or after an evacuation of the bowels, and is associated with wriggling movements of the body and pelvis and with eruc- tation or the passage of flatus. Conditions of general distress or malaise predispose to fits of fretful crying, the paroxysms being excited by any dis- turbing influence, or even by merely looking at the little sufferer. When the cry has a nasal tone, it indicates swelling of the mucous mem- brane of the nares or other obstructing condition. Thickening and indistinct- ness occur with pharyngeal affections. A loud, brazen cry is a precursor of spasmodic croup. Hoarseness points to a lesion of the laryngeal mucous membrane, either catarrhal or syphilitic in nature. In membranous croup and in some cases of extreme exhaustion the cry is faint and inaudible. Finally, in severe croupous pneumonia, in extensive pleural effusion, and in rickets ordinary disturbing causes are inoperative for the production of fits of crying, and there is a seeming unwillingness to cry, on account of the action interfering with the respiratory function. The conditions of altered tone apply equally to the articulate voice in children who are old enough to speak. The cough, too, must not be disregarded. Many of its characters corre- spond with the voice and cry. It is brazen in spasmodic croup, suppressed in true croup, hoarse in laryngeal catarrh, and so on. But it has certain fea- tures of its own. In bronchitis it is more or less paroxysmal, evidently dry in the early stages, loose and rattling as the catarrh "breaks up." In the CLINICAL INVESTIGATION OF DISEASE. 7 painful pulmonary affections, pneumonia and pleurisy, it is choked back, and ■whenever it occurs an expression of pain passes like a cloud over the face. In pertussis the peculiar spasmodic cough is the pathognomonic symptom. Cough is always unproductive — that is, unattended by expectoration — in. children under seven years of age. The formation of tears rarely begins before the third or fourth month of life. Subsequently, an alteration in this secretion may be of aid in fore- casting the result of disease. The prognosis is bad when the tears become suppressed ; good when the secretion continues during an illness or when it reappears after being suppressed. There are several other sources of information Avhich should be investi- gated before proceeding to the physical examination, although, strictly speak- ing, they do not come under the head of inspection of the child. These are the alterations in the odor of the breath, and the characters of the fjecal evacu- ations, of the urine, and of material ejected by vomiting. The Breath. — The breath of a healthy child is odorless, or, as the nurse will say, " sweet,'" except perhaps immediately after taking nourishment, when it may, for a short time, have the smell of milk or other food. Any persist- ent odor is abnormal. Any morbid condition of the system ^lat prevents the elimination of meta- morphosed nitrogenous tissue through the mucous membrane of the intestines or retards the passage of decomposing detritus along the bowels will cause an offensive breath. Under this head are conditions characterized by high tem- perature, catarrhal inflammation of the gastro-intestinal tract, chronic debili- tating diseases, etc. The same result also frequently attends structural lesions of the kidneys. The reason for this is, that the system, in order to get rid of poisonous matter — for accumulated waste is poison — and to maintain the balance between the constant construction and destruction of tissue, must throw off elsewhere what the intestinal glands and the kidneys fail to excrete ; so the lungs take on vicarious activity and the expired air becomes tainted. Purely local causes of halitosis also exist. These are decayed teeth, caries of the nasal and maxillary bones, ulceration of the mucous membrane of the mouth, nose, larynx, trachea, and bronchial tubes, and gangrene of the cheeks. Chronic poisoning by lead, arsenic, or mercury, though not very common in childhood, is another cause of ill-smelling breath. To speak in general terms, the breath may become sour, catarrhal, foetid, gangrenous, ammoniacal, and stercoraceous. Sour breath is present, in infants moi^e especially, when there is gastric fermentation. Catarrhal breath has numerous shades of difference. In chronic catarrh of the pharynx there is a "heavy" odor, not noticeable far from the patient's face. It is always most marked during and after sleep. Should there be associated follicular tonsilli- tis, the breath, while still heavy, becomes extremely offensive, with a scent somewhat like that of decaying cheese, and is very penetrating. This odor, too, is worse after sleeping. At the onset of acute catarrh of the stomach the breath sometimes has a vinous odor, at others it is sweetish, and again it has the same quality as after an inhalation of ether. Later in the attack it becomes sour or has the odor of sulphuretted hydrogen. What is known as a " feverish breath " has a heavy, sweetish smell. It is met with in diseases of high temperature ; thus, it is very marked and rapid in appearance in scarlatina. Foetor of the breath is observed in its mildest form in such affections as aphthae and ulcerative stomatitis. It is better developed in oztena and necrosis of the maxillary bones. Decaying teeth give much the same odor, though it is less strong and penetrating. 8 AMUBICAN TEXT-BOOK OF DISEASES OF CHILDREN. Noma gives rise to a gangrenous odor, and a patient so affected will fill the room in which he lies, or even a whole dwelling, with the most sickening stench. Cases of empyema, with ulceration of the lung and discharge of pus through the hronchial tubes, have an almost equally offensive breath, but here there is often a superadded flavor of garlic. Ammoniacal hreath is observed only in patients suffering with ursemic poisoning. A purely stercoraceous breath is rare, and when met with is an accompaniment of ftecal tumor or of intussusception. The different metallic poisons give rise to no characteristic odor, and it is necessary to look to the clinical history to determine the special poison. The' F.ecal Evacuations. — The daily number of evacuations natural for a child varies greatly with its age. For the first six weeks there should be three or four stools every twenty-four hours. After this time, up to the end of the second year, two movements a day is the normal average. Sub- sequently, the frequency of defecation is usually the same as in adults — once per diem. During the first period the stools have the consistence of thick soup, are yellowish-white or orange-yellow in color, with sometimes a tinge of green, have a taint focal, slightly sour odor, and are acid in reaction. In the second they are mushy or imperfectly formed, of uniform consistence through- out, brownish-3'ellow in color, and have a more f^cal odor. The last two charac- ters become more marked as additions are made to the diet. After the comple- tion of the first dentition the motions have the same appearance as in adult life; they Vive formed, and brownish in color, with a decided fiecal odor. Many alterations occur in disease. The frequency of the movements may be increased, constituting diarrhoea, or lessened, constituting constipation. In the former condition the consistency is diminished, in the latter increased. Instead of being uniform throughout, the stool may be mixed, partly liquid, partly solid, indicating imperfect digestion, and curds of milk and pieces of undigested solid food may be mingled with the mass. Flaky, yellowish, or yelloAvish-green evacuations, containing whitish, cheesy lumps, are also met in cases of indigestion. Scanty, scybalous stools, dark-brown or black in color, and mixed with mucus, are characteristic of intestinal catarrh. Doughy, grayish, or clay-colored motions show a deficiency of bile. An intermixture of blood, altered blood-clots, and shreds of mucous membrane indicate some breach of continuity in the intestinal lining, such as occurs in follicular ente- ritis, typhoid fever, dysentery, and tubercular disease. Watery, almost odor- less stools occur in the latter stages of entero-colitis, most offensive, carrion- like motions in both catarrhal and tuberculous ulceration of the intestines, and sour-smelling evacuations in the diarrhoea of sucklings. The discovery of worms or their ova in the stools is the certain evidence of the existence of intestinal parasites. This outline of the changes that may take place will serve to show how much may be learned from the stools, and the importance of making a per- sonal examination of them. The Urine. — It is impossible to make a definite statement as to the num- ber of times the urine is voided by a healthy infant in each twenty-four hours. In any given case the frequency will differ very much from day to day, depend- ing upon the temperature of the surrounding air, the amount of moisture that it contains, and so on. Sometimes it will be necessary to change the diaper every hour during the day and three or four times at night. Again, it may remain dry for six, eight, or even ten hours. Neither condition indicates dis- ease, and between the two extremes there is a wide range of variation. Should the urine not be passed for twelve hours or more, a careful examination should CLIXICAL INVESTIGATIOX OF DISEASE. 9 be made to discover and remedy retention. As the child grows older the fre- quency diminishes, and at the age of three years the number of voidings will be reduced to six or eight during the waking hours, and perhaps one at night. When the desire does arise during sleep, the child, if in a normal state, wakes up and demands the chamber, and never passes urine unconsciously. Wetting the bed, therefore, or the involuntary passage of the urine during sleep, is indic- ative of an abnormal condition and requires investigation. Painful micturition points to inflammation of the urethra, a narrow preputial orifice, a highly acid condition of the excretion, or stone in the bladder. The urine of a healthy infant, while it wets, should not stain the diaper, the fluid being clear and almost colorless. It has a low specific gravitv — 1.003 to 1.006 — and an acid reaction. As age advances the adult characters are more and more nearly approached, though during the whole of childhood the urine is paler and of lower specific gravity than in adult life. The normal daily amount excreted cannot be stated absolutely, but the following figures are approximate : Between two and five years, 15^25 oz. ; five and nine years, 25—35 oz. : nine and fourteen years. 35—40 oz. Other characters of the urine in childhood will be considered under appropriate headings in subse- quent sections. Vomiting. — Both vomiting and regurgitation are of ready production and frequent occurrence in infancy, on account of the vertical position and cylin- drical outline of the stomach at this period of life. Babies suckled at an abun- dant breast, and who are in perfect health, often vomit habitually. In these cases, the supply of food being large, the infant as it lies at the breast is apt to draw more than it can digest. The stomach rids itself of this over-supply by an act which more nearly resembles regurgitation than vomiting, and which must be regarded as an evidence of health rather than the reverse. There is no violent e9"ort or retching; the material ejected is the breast-milk alone, either entirely unaltered or slightly curdled ; and there are no symptoms of nausea, such as paleness, languor, and faintness. In older children vomiting may also occur after the stomach has been overladen. If the act be followed by relief from the general distress, headache, and epigastric pain, it must not be regarded as a symptom of disease. Vomiting attended with the train of symptoms embraced under the term nausea is not a pathognomonic symptom. It may indicate disease of the stomach, of the intestines, of the lungs and pleura, and of the brain, or it may be a prodrome of one of the eruptive fevers. Which condition is pres- ent can only be determined by watching the case. The character of the ejecta is more definite. For instance, the expulsion of mucus is a symptom of gas- tric catarrh. The regurgitation of mouthfuls of curdled milk, partially digested food, and liquid so sour that it causes a grimace to pass over the face, is an indication of dyspepsia, with fermentation and the formation of acid. The appearance of lumbricoid worms in the vomit — a not infrequent occurrence — of course shows conclusively the existence of these parasites in the alimen- tary canal. 3. Physical Examination. The methods of physical exploration in children are identical with those employed in adults, and the results do not difi'er in kind. Since, however, the object of exploration is to elicit the greatest amount of information with the least possible disturbance of the child, and as this very disturbance alters the character of some of the information obtained, it is well to adopt a somewhat different order of examination, and one which at first sight may seem irregular. 10 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Thus it is best first to ascertain the character of the respiration and the pulse, then to strip the body to determine the degree of muscular development and the condition of the skin, next to investigate the physical condition of the lungs, heart, and abdominal oi-gans, and last of all to examine the mouth and throat. In this order, then, the normal, as well as the more prominent abnormal, fea- tures connected -with the different organs will be considered. The Respiration. — In children the respiration is chiefly abdominal in type, irrespective of sex, and it is not until just before the age of puberty that the movements in the female change, becoming superior costal. Consequently, in estimating the number of movements per minute, it is best to place the fingers lightly on the epigastrium. The count should always be made by the watch, and the most convenient time for the observation is while the child sleeps. Soon after birth the number of movements per minute is 44, between the ages of two months and two years, 35, and between two and twelve years, 23. During sleep the frequency is reduced about 20 per cent. Children under two years, while awake, breathe unevenly and irregularly. In sleep there is greater regularity. After the second year the movements become steady and even. All children, however, but particularly the very young, are subject to a great increase in the rapidity of respiration under excite- ment, either muscular or mental. Accelerated breathing may be caused by an elevation in the body temper- ature, by an interference with the blood aeration, and by thoracic or abdominal pain. As the increase in frequency may be unattended by any apparent effort or true dyspnoea, it is well to make a rule of counting the respirations in every case in which the diagnosis is doubtful. Diminished frequency is noted in certain brain aff"ections, as in chronic hydrocephalus, and in the later stages of tubercular meningitis. In such cases the rhythm may be greatly altered — a tidal form being assumed ; this is termed " Cheyne-Stokes respiration." Another form of breathing, in which the alteration is mainly in the rhythm, is termed expiratory respiration. It is characterized by the pause coming between inspiration and expiration, instead of between expiration and inspiration, as is the normal rule. This alteration occurs most frequently in young children, and is an evidence of dangerous pulmonary embarrassment. Perfectly healthy children breathe through the nose, and so softly that it is difficult to hear the breezy sound of the ingoing and outgoing air. A dry, hissing sound or a moist sound of snuffling indicates partial obstruction of the nasal passages ; oi'al respiration, complete occlusion. DiflScult breathing with prolonged inspiration — inspirator^/ di/spnoea — shows an impediment to the entrance of air into the lungs and indicates laryngeal obstruction, due, most commonly, to spasm or to the formation of false membrane. In such cases the inspiratory act is also attended by a loud, piping, or rasping sound. Labored breathing with prolonged wheezing respiration — expiratory dyspnoea — occurs when the escape of air is impeded. The causative lesion is to be found, not in the larynx, but in the lungs. It may be a bronchial catarrh with excessive secretion, emphysema, or asthma. In both forms of dyspnoea the movements are slow as well as difficult, and a combination of the two forms is met Avith in cases of marked laryngeal stenosis. Yawning, if it recur frequently, denotes great failure of the vital powers. The Pulse. — To obtain any reliable data from the pulse it must be felt while the patient is perfectly quiet. The best time is during sleep, but if the child cannot be caught in this condition, advantage may be taken of its pla- cidity while nursing at the breast, feeding from a bottle, or amused by a toy. CLINICAL INVESTIGATION OF DISEASE. 11 With very young infants it is sometimes impossible to feel the beat of the radial artery, and it is necessary to ascertain the frequency of the pulse by directly auscultating the heart. After the second month palpation of the pulse at the wrist in the ordinary way presents no difficulties. The child's pulse differs from the adult's by being much more frequent, more irregular, and more irritable, and necessarily of smaller volume. The frequency, or the number of beats per minute, varies with the age. The following is the average rate : From birth to the second month . 160 to 130 From the 2d to the 6th month 130 to 120 " 6th " 12th " 120 to 110 " 1st " 3d year 110 to 100 " 3d " 5th " 100 to 90 " 5th " 10th " 90 to 80 " 10th " 12th " 80 to 70 These figures represent the pulse in a waking but passive state. During sleep the frequency is less. Thus, between the second and ninth years there are about sixteen beats less per minute while asleep than when awake ; between the ninth and twelfth years, eight less ; and between the twelfth and fifteenth years, only two less. Below the age of two years the disparity is even greater. The irregularity of the pulse in childhood is confined to an alteration of the rhythm. It is most marked in infants, and is greatest during sleep, when the pulse is slowest. The feature of irritability — that is, the facility with which its frequency is increased by muscular activity and mental excitement — is greater in proportion to the youth of the child. A rise of 20, 30, or even 40 beats a minute is not uncommon in early infancy under the excitement of the slightest effort or disturbance. On account of these wide variations in health little symptomatic meaning need be attached to alterations of the rhythm and fre- quency while unassociated with other abnormal features. When so associated they become important in diagnosis. Increased frequency is a constant attendant of the febrile state. The extent of the increase corresponds with the degree of elevation of the temperature, though the pulse curve always runs higher than the temperature curve. The more frequent the pulse the higher the fever is the rule, but in estimating the prognostic value of the increase the law of the fever in question must be taken into consideration. For example, in scarlatina a pulse of 160 is usual and not indicative of special gravity, whereas in measles the same degree of accelera- tion would be abnormal and show great danger. Jaundice and parenchymatous nephritis are accompanied by a diminution in the rate. Irregularity is met with in diseases of the brain and heart, and sometimes in nervous and anaemic children. The Temperature must be estimated before removing the clothing, and a clinical thermometer must always be used. The instrument is usually placed in the rectum or groin ^ of the infant and young child ; in the axilla of one old enough to understand the importance of keeping the arm in a proper attitude. It should remain in position at least five minutes. During the first week of life the temperature fluctuates considerably. After that the puerile norm — 98.5° to 99° F. — is established, but until the fourth or fifth month it is greatly influenced by healthy causes of variation, the fluctua- tions ranging between 0.9° and 3.6°. By the fifth month regular morning and evening oscillations begin and certain definite laws are followed. There is a ' The rectal temperature is normally 1° higher than the axillary ; that of the groin about 1° lower. 12 A3f£IiICA^^ TEXT-BOOK OF DISEASES OF CHILDREN. liill in the evening of 1° or 2°. The greatest fall occurs between 7 and 9 P. M., and the minimum is reached at or before 2 a. m. After 2 a. m. there is a grad- ual rise, the maximum being reached between 8 and 10 a. m. Throughout the day the oscillation is trifling. These variations are independent of eating and sleeping. In disease there may be either a rise above or a fall below the normal standard. Fever is always associated with an elevation of the temperature. Rapid and transient rises attend slight catarrhs and passing indigestions ; pro- longed rises, inflammatory and essential fevers. The degree of elevation marks the type of the pyrexia. This is moderate when the mercury stands at 102°, severe at 104° or 105°, and very grave above 107°. The duration of the ele- vation and the peculiar range of the oscillations — for there are oscillations in disease as well as in health — determine the nature of the fever. The febrile oscillations differ from the healthy in that the lowest marking is noticed in the morning, the highest in the evening. Variations in the typical range of any given fever are important prognostic omens: a sudden fall of temperature, together with improvement in the general symptoms, indicates the beginning of convalescence ; a similar fall, with an increase of the general symptoms, is a precursor of death. When the morning temperature is equal to that of the preceding evening, there is great danger ; if higher, greater danger still. Marked remission in continued fevers is generally a forerunner of con- valescence. Abnormal depression of temperature is occasioned by haemorrhage and by the loss of fluids in profuse watery diarrhoea. It is also met with in anemia, in atrophy from insufficient nourishment, in diseases of the heart and lungs attended by imperfect blood-aeration, and it constantly attends collapse and the death agony. A maintained temperature of 97° F. is dangerous in chil- dren, and for every degree of reduction below this point the risk to life is more than proportionately increased. The General Development. — The healthy child under two years of age is plump of body and round of limb, with well-developed fat cushions and firm flesh, and with the head and abdomen large in proportion to the rest of the frame. As age advances the figure gradually assumes the characteris- tics of adolescence. To be robust, the newly-born child must have a certain average size and weight. Subsequently, under normal circumstances, there is a regular rate of increase in both of these respects. At birth the length is about 16 inches. Growth is quickest in the first week of life. In the first year there is an increase of from 5 to 6 J inches ; in the second, from 2| to 3|^ inches ; in the third, from 2^ to 2| inches ; in the fourth, about 2 inches ; and from the fifth to the sixteenth year the annual growth amounts to from It to 2 inches. The average weight at birth is from 6 to 8 pounds. The daily increase in weight should range from i to | of an ounce. AVith these data it is quite possible to estimate what should be the normal size and weight of a child at any age. Consequently, if. on being measured and Aveighed, he be found to fall short of the normal standard, it is proper to infer the existence of some fault in the nutritive processes — a conclusion still further borne out by a want of rotund- ity of outline and by flabbiness of the muscles. The age at which the child sits erect, at which it walks, and at which the anterior fontanelle becomes ossified are points closely connected with the sub- ject of development and nutrition. For some time after birth the child, if noticed while sitting upon the lap, will be observed to hold the head and shoulders forward or to "stoop" a little, the spine from the cervical region CLINICAL INVESTIGATION OF DISEASE. 13 to the sacrum forming a continuous curve, with the convexity directed back- ward. Toward the end of the eighth month the position begins to become more erect, and in a few weeks is perfectly so, the spine assuming an almost perpendicular line. Any marked delay in this change indicates general debility. At the end of the fourteenth month the child should be able to walk alone. The spine then assumes the S-like curve seen in healthy adults. A delay in walking may be due to systemic weakness or infantile paralysis affecting one or both legs. If the walking be done on the toes chiefly, if the gait be limping, and especially if knee-pain be complained of and manipulation of the limbs causes suffering, the chances are that hip-joint disease is com- mencing. The anterior fontanelle should be ossified or completely closed at some period between the fifteenth and twentieth months. The closure is much retarded in rickets, which is pre-eminently a disease of malnutrition. Hydro- cephalus has a like effect. In a state of health the opening, while still mem- branous, is level with the cranial bones or very slightly depressed. Conditions of systemic exhaustion cause marked sinking, and this depression is one of the best indications of the necessity of stimulation. Bulging of the fontanelle is a symptom of chronic hydrocephalus. Conditions of the Skin. — In addition to the characters already described, the skin of a healthy child has a velvety smoothness and softness, a scarcely perceptible moisture, and a great degree of elasticity. "Mucous disease" is attended with a dry, harsh skin, which is muddy in color, and covered, especially on the extensor surfaces of the arms and legs, by a more or less thick layer of exfoliating epidermis. Chronic abdominal affections, particularly tuberculosis of the intestines and mesenteric glands, lead to harshness, acridity, scurfiness, and a wrinkled appearance of the skin covering the abdomen and thorax, with enlargement of the superficial abdom- inal veins. Protracted diarrhoea, and, still more, vomiting combined with diarrhoea, cause absorption of the subcutaneous fat and wasting of the mus- cles. The skin becomes too large for the body, is dry, harsh, discolored, and so inelastic that it falls into wrinkles over the joints when the limbs are moved, and if pinched up retains the fold for a long time. The condition of general atrophy popularly known as "marasmus" presents these features most strik- ingly. Dryness is a concomitant of the febrile state ; excessive moisture, of prostration and collapse. Eruptions appear upon the integument in the skin diseases proper, in the exanthemata, in constitutional syphilis, and in certain digestive disorders. Oedema of the subcutaneous connective tissue may be due to affections of the heart, liver, or kidneys. The cardiac variety usually shows itself first in the feet ; the renal, in the eyelids ; the hepatic, in the feet and legs, secondarily to ascites. While examining the surface it is well to look for enlargement of the super- ficial lymphatic glands and swelling of the joints. The former occurs in tuber- culosis and syphilis ; the latter, in rheumatism. Examination of the Abdomen. — To examine this portion of the body, the child, still stripped, must be placed on its back and kept as quiet as possi- ble. Palpation or percussion should never be made with cold hands. The abdomen of a healthy child is prominent, uniformly soft, yielding, and painless to the touch, and to percussion gives a tympanitic sound, varying in tone according to the region percussed. The tympanitic note is lowest in pitch over the epigastric and left hypochondriac regions, the seat of the stomach ; highest over the umbilical region, the position of the small intestine. In disease inspection reveals any disproportion in the size or form of the abdomen, the state of the integuments, of the superficial veins, and of the 14 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. umbilicus. Palpation shows the temperature, pliability, moisture, and tension of the walls, and the presence or absence of tenderness, of fluctuation, and of enlargement of the mesenteric glands and other solid viscera. Percussion serves to demonstrate tlie nature of enlargements, Avhether due to accumulation of gas or liquid or to solid groAvths. By it, also, the outline and size of the liver and spleen may be determined. Distention of the abdomen is, in the vast majority of instances, due to flatulence. In this condition the skin feels tense, the umbilicus is level or slightly prominent, there is no tenderness on pressure, and percussion is markedly tympanitic. Drum-like distention, with great tenderness, and mufiled tympanitic percussion-note occur in general pei'itonitis. Uniform distention, again, may be due to ascites. The abdomen is barrel-shaped, painless to the touch, and there is extended fluctuation. Percussion is dull over the position of the fluid, but in nearly every instance there is an area of tympany which changes its position. Localized distention may be traced to gaseous accu- mulation, to enlargement of the liver and spleen, to ftecal accumulation, to circumscribed peritonitis, and to distention of the bladder. Collections of gas are always t^^mpanitic on percussion. The extent of liver dulness is to be estimated by percussion, or palpation with the warmed hand. An enlarged spleen may be felt by placing the fingers of the right hand on the back, directly below the twelfth rib and outside of the lumbar muscles, the fingers of the left on the abdomen, directly opposite, then bringing the hands toward one another. The fact that both the liver and spleen, though still unenlarged, may be more readily felt than natural when pressed downward by the dia- phragm, must not be overlooked. A foecal accumulation is distinguished by the absence of tenderness, by the oblong shape of the tumor, by the situation in the region of the transverse or descending colon, to which its long axis cor- responds, and by its shape being capable of some modification by pressure. Percussion over such a mass is dull. Distention of the bladder gives rise to a bulging tumor in the hypogastric region, which is elastic to the touch and dull on percussion. A shrunken or scaphoid condition of the abdomen is met with in serious brain affections, notably tubercular meningitis, also in entero-colitis, follicu- lar enteritis, and dysentery. Tenderness to pressure indicates inflammatory lesion of the intestines. The presence or absence of this sign in an infimt can be determined by forcing the attention, by bringing it before a strong light, for instance, and then making pressure on the abdomen. If crying be produced, there is tenderness ; if not, the reverse. Examination of the Chest. — The stethoscope and pleximeter are unne- cessary in examining the lungs. In the case of the heart the former may be occasionally required to localize murmurs. When used, it is better to give the instrument to the child to handle and become familiar with before application. The thoracic end must never be adjusted without being warmed. The quieter the patient, the more complete and satisfactory will be the results of the explo- ration. Unfortunately, though, it is too often necessary for one to do the best possible in the midst of cries and struggling. HoAvever, by skilfully seizing opportune moments much reliable information may be gained. The steps of the examination are — first, inspection ; second, auscultation ; third, palpation ; and fourth, percussion. The reason for making the order different from that practised in adults is to place the most disturbing element last. Mensuration and succussion are infrequently resorted to in children. If required, they are best postponed until the end of the examination. CLINICAL INVESTIGATION OF DISEASE. 15 Inspection. — The sitting posture, the child being stripped and in a good light, is the best for this process. Note is to be taken of the shape of the chest, the character of the breathing, and the position of the apex-beat of the heart. In the new-born baby the chest is nearly circular in shape ; later, the lateral diameter considerably exceeds the antero-posterior. The intercostal spaces are poorly marked, and the scapulae lie so close that their outline is scarcely perceptible. The circular shape of the chest allows of little lateral expansion, and for this reason the respiration is chiefly abdominal in type. Together with the movement of the abdominal walls, every act of inspiration is attended by a certain amount of recession of the lower part of the chest- walls, the yielding ribs being forced inward by the pressure of the external air before they can be sufficiently supported by the expanding lung. The rise and fall of the cardiac apex can be seen — except when there is a great accumulation of fat — a short distance below and to the right of the left nipple. Disease may alter all of these conditions. The tuberculous diathesis is characterized by a small chest, and one which has either the alar or the flat shape. In rickets the thorax becomes irregularly triangular in outline. Em- physema causes a barrel-shaped chest, with stooping shoulders and round back. Pleuritis with large effusion produces bulging of the affected side, and some- times prominence of the intercostal spaces. After absorption has taken place there may be marked retraction, sinking of the interspaces, falling of the shoulders, and curvature of the spine toward the healthy side. Cessation of the costal respiratory movements indicates inflammation of the lung or pleura or a large pleuritic effusion ; cessation of the abdominal play, inflammation of the peritoneum or of the intestines : excessive ascites and gaseous accu- mulations produce the same effect. Rachitic softening of the ribs, and those diseases of the lungs which offer a direct obstacle to the entrance of air, are associated with a great increase in the normal recession of the lower portion of the chest on inspiration. The position of the apex-beat is altered by car- diac diseases, by pleuritis, and occasionally by gaseous distention of the stom- ach. When the left ventricle is enlarged, it is shifted downward and to the left. Transmitted epigastric pulsation shows enlargement of the right ventricle. An extended impulse is not necessarily a sign of disease, since the chest-walls are so elastic in childhood that the normal impact of the apex is apt to affect a wide area. The effusion of pleurisy pushes the heart to the right or left, while the retraction, after absorption or evacuation, draws it in one or other direction. The apex is pushed upward and to the left in gastric flatulence. Emphysema, by pushing the heart away from the thoracic wall, diminishes or hides the impulse. Auscultation. — With infants the back of the chest is most conveniently ausculted when the child is held in the nurse's left arm, with his breast against hers, his chin resting upon her left shoulder, his left arm around her neck, and his head kept in position by her disengaged hand ; the front, when reclining on the back on a pillow ; the sides, when sitting upright on the lap, first one arm and then the other being lifted up to allow the observer's ear to be applied. Older children may be made to take the same position as adults. It is not suf- ficient to auscult the posterior aspect of the thorax alone, as is stated by some authors. The whole chest should be examined, particularly in doubtful cases. The signs of croupous pneumonia are most frequently discoverable at one or other base, posteriorly; the friction- sound of pleuritis at the junction of the middle and lower third of the chest, laterally ; and the signs of emphysema at 16 AMEBICAX TEXT-BOOK OF DISEASES OF CHILDREN. the apices, anteriorly. Therefore, unless the exploration be thorough, import- ant lesions may be overlooked. In healthy infants the inspiratory act in ordinary breathing is superficial, and the respiratory murmur, as a consequence, feeble. If, however, a deep inspiration be taken, a frequent occurrence under excitement and during cry- ing, the murmur becomes loud, or iJuerUe. After the age of two years puerile respiration is habitual. The breathing is loudest over the anterior, lateral, and posterior inferior regions of the thorax ; faintest over the scapulae and the prae- cordial area. Sometimes the expiratory element is wanting in young children over the lower posterior portions of the lungs. In the interscapular region there is often an approach to the bronchial type of breathing. If the child speaks, cries, or coughs while the ear is applied to the chest, a muffled rumbling sound, the normal vocal resonance, will be heard. At the same time vibra- tion of the walls, the vocal fremitus, can be felt. The cardiac sounds are readily heard when the ear is placed on the proecor- dia. In young infants the examination is somewhat difficult, but after the first year, the circulation becoming slower and more regular, there is little trouble in distinffuishing the sounds, and even slio:ht alterations in them. The first sound is longer and graver than the second, the rhythm is ordinarily quite regular, and the area of distribution is extended. Palpation. — In practising palpation the palmar surface of the well-warmed hand must be applied to the naked chest. This method of exploration is use- ful as a means of determining the number of respiratory movements, the degree of expansion of the thoracic walls, the position of the cardiac apex-beat, the presence or absence of painful regions and of pleural or bronchial fremitus, the existence of fluctuation in the intercostal spaces, and the character of vocal fremitus. Percussion. — In percussing the different surfaces of the chest the child must be placed in the same position as for auscultation. When contrasting the two sides, percussion should be made in identical regions and during the same period of the respiratory movement. Babies when constrained or when disturbed hold their breath in the intervals of crying, and as they always do so at the end of an inspiration, this is a favorable time to seize for the compar- ative examination. The percussion strokes must be lighter than in the adult, but in other respects the operation in no wise differs. In health the resonance will be found to correspond closely Avith the res- piratory murmur. Thus in infants under one year, the respiratory murmur being feeble, percussion is rather insonorous, but so soon as puerile respiration becomes established the resonance is uniformly intense. With the exception of this greater intensity the sound is exactly similar to that obtainable in adults. It is always attended, too, by a sensation of elasticity, appreciated by the finger used as the pleximeter. Different portions of the thorax possess, normally, different degrees of sonor- ousness. In front, the right side is markedly resonant from the clavicle down to the fifth interspace or the upper border of the sixth rib in the mammary line, where the liver dulness begins. On the left side the resonance is equally intense, but it is encroached upon by the gastric tympany, which extends upward as high as the seventh or sixth rib, as well as by the area of car- diac dulness. The latter is never so decidedly marked as in adults. Later- ally, both axillary regions are very resonant. The upper portions of the infra- axillary regions are a degree less resonant, and the lower portions are dull on account of the presence of the liver on the right and the spleen on the left side. The superior border of the liver dulness is found in the seventh interspace, or CLINICAL INVESTIGATION OF DISEASE. 17 at the eighth rib ; that of the spleen, at the upper edge of the ninth rib. Gas- tric tympany may supplant the pulmonary resonance over the left infra-axillary region. Posteriorly, there is little resonance in the scapular region, partic- ularly the supraspinous portions. Over the interscapular space the sound improves, but it is less resonant than anteriorly or laterall3\ Over the infra- scapular regions the resonance is but little less pure than in front, until the tenth rib is reached on the right side and the liver dulness is again met with. On the left side the resonance extends to the very base, the posterior splenic dulness being detected with difficulty. The right base is, therefore, naturally less resonant than the left, and this difference is especially marked during expi- ration, the liver rising higher at that time. Affections of the lungs produce various alterations in the percussion sound. The chief of these are the substitution of tympany, of dulness, and of flatness for the normal resonance, and of increased resistance to the finger for elasticity. Cardiac diseases cause changes in both the extent and the shape of the area of praecordial dulness. Examination of the Mouth axd Fauces. — This portion of the exami- nation is most apt to cause crying, but it must never be omitted. In infants gentle pressure of the fingers upon the chin is sufficient to cause wide opening of the mouth. An older child will frequently open the mouth when requested, but if he refuse, some smooth, flat instrument may be inserted in the mouth, and downward pressure made upon the tongue, when the jaws will be widely separated. The fauces can sometimes be seen by directing the mouth to be opened wide and the tongue to be alternately protruded and retracted, or a pro- longed sound of "^7i " to be made. With the refractory, and always with infants, the tongue has to be held down by a spoon-handle or tongue-depressor. The healthy oral mucous membrane has a deep pink color and is smooth, moist, and warm to the touch. The color is deeper on the lips and cheeks, lighter on the gums. The latter, up to the sixth month, as a rule, have a mod- erately sharp edge. Subsequently, the edge begins to broaden and soften, and the color of the investing mucous membrane deepens to a vivid red, and becomes hot as the teeth begin to force their way through. The first, or milk teeth — so called from their color — are twenty in number, all told, ten to each jaw; the two lower central incisors, the first of the set, make their appearance at some time between the fourth and seventh months, the others following at stated intervals.^ The permanent teeth, thirty-tAvo in number, begin to appear about the sixth year. The tongue should be freely movable. It is pink in color, and the dorsum, or upper surface, marked in the centre by a slight longitudinal depression, has a velvety appearance, and is soft, moist, and warm to the finger. The hard pal- ate is roughened anteriorly by transverse ridges. The soft palate is smooth, and its mucous membane is paler than that of the rest of the mouth. The fauces, on the contrary, are redder. In the triangular recess between the half-arches of the palate the tonsils can always be seen. They should be about the size and shape of almond-kernels, and they present a number of circular open- ings, the orifices of pouches into which the follicles open. The uvula is short and tongue-shaped. The posterior wall of the pharynx should be red, smooth, and moist. Disease produces a great variety of changes in the mouth, tongue, and fauces. Fever makes the mouth hot and dry and causes the tongue to be frosted or coated. Affections of the gastro-intestinal tract are always attended by coating of the tongue, and the various appearances of this coating are of ^ See article on Dentition. 2 18 AMUBICAX TEXT-BOOK OF DISEASES OF CHILDREN. important diagnostic and therapeutic significance. Inflammation of the mouth itself reddens the mucous membrane, makes it hot and tender to the touch, increases its moisture, alters the surface of the tongue, and leads to the forma- tion of aphth?e, to ulceration, and even to gangrene. The eruptions of scar- let fever, measles, varicella, and varioloid make their appearance first on the mucous membrane of the palate and fauces. Finally, the conclusive evidences of diphtheria and of the various tonsillar affections are found in the fauces. Irregular dentition indicates faulty nutrition ; delayed dentition, rickets : and certain peculiarities in the formation of the permanent teeth, constitu- tional syphilis. n. The General Management of Children. 1. Feeding. The whole question of feeding bears .so close a relation to age that it is necessary to study it from the standpoint of the two stages of a child's life already mentioned. An infant may be fed in one of three ways : 1st, from the mother's breast ; 2d, from the breast of a wet-nurse : and 3d, from a bottle by the method known as artificial or hand-feeding. 1st. Feeding from the Maternal Breast. — This, being the natural, is the proper method of nouri,shing the human infant ; and every mother who is able should nourish her child solely from her breast up to the age of eight months, and partially to the end of the first year, or, failing in either limit, so long as possible. The infiint should be put to the breast as soon as the mother has recovered somewhat from the fatigue of labor — some four or eight hours after birth. Of course no milk can be draAvn at this early date, but the babe gets a small quantity of colostrum, which affords sufiicient nourishment, and from its laxa- tive properties clears out the infants intestinal canal. This, too, is of great advantage to the mother, for it ensures proper uterine contraction, draws out the nipples, and encourages the formation of milk. Put the child to the breast every two hours while the mother is awake, and up to the fourth day there need be no fear of starvation. Usually on the fourth day milk is secreted and regular lactation commences. Before this time the administra- tion of gruel or any form of artificial food is more than useless, as it lessens the activity of sucking and frequently deranges the stomach. Many untrained mothers make a failure of nursing because they know nothincj of the manner of givincr suck : of the length of time the child should be kept at the breast ; of the proper time for. and interval between, feedings : and of the importance of regularity. While nursing the infant must be held partly on its side, on the right or left arm according to the gland about to be drawn, while the mother must bend her body forward, so that the nipple may fall easily into the child's mouth, and steady the breast and regulate the flow of milk with the fii'st and second finger of the disengaged hand placed above and below the nipple. Each of the breasts should be drawn alternately, and a healthy child may be allowed to nurse until satisfied. Usually durinfr the fir.st six weeks the breast is required every second hour from .5 a. m. until 11 P. M., and in some cases once during the night ; but this night-nursing should be given up as soon as possible, that the mother may secure essential repose. Regularity in meal hours is most important, and a little perseverance will form the habit of waking to suck the breast with almost the precision of the clock. This rule, GENERAL MANAGEMENT OF CHILDREN 19 however, is not rigid, some infants requiring food less, others more, frequently. These exceptions can only be determined by observation of individual charac- teristics, and every mother must early learn to distinguish the cry of hunger from that due to the pain of indigestion, and avoid the dangerous practice of resort- ing to constant feeding as a means of pacifying crying. After the sixth week the interval between nursings may be slowly increased until, by the fourth month, it reaches three hours. During this pei'iod, also, the time of lying at the breast may be gradually lengthened, for the quantity of milk secreted and the child's appetite and capacity for food are all aug- mented as the days pass by. At the end of the sixth month feeding every fourth hour suits some children well, but as a rule the three-hour interval must be adhered to from the fourth month to the end of lactation. After the sixth or eighth month " mixed feedinoj " — breast- and bottle- ~ . . . feeding alternating — is advisable if the babe ceases to thrive on the breast alone. Otherwise, the maxim of not interfering with any course that is doing well is as applicable here as elsewhere, and the breast may be relied upon entirely until the time comes for weaning. Should additional nutriment be required, the food must be selected with due reference to age and prepared in the same manner as in regular hand-feeding. The date of weaning cannot be fixed for all cases, since it depends upon the health of the mother and the development of the child. When the former continues to be robust and the child steadily grows and gains flesh, lactation can be prolonged until the tenth or twelfth month. If persevered in longer, the mother's strength usually begins to fail, her milk is lessened in quantity or becomes poor in quality, the child's nutrition suffers, and it grows pale, thin, and flabby, and may develop the disease known as rickets. Weaning may be accomplished gradually or suddenly. In gradual wean- ing about four weeks are required to prepare for the absolute withdrawal of the breast. For instance, if suck be given every three hours from 5 A. M. until 11 P. M., or seven times a day, there should be, during the first week of preparation, one artificial feeding and six nursings daily ; during the sec- ond, two and five, and so on until the breast is entirely withheld. Carefully prepared milk food, administered from a bottle, is the best substitute. At the age of ten months a mixture that ordinarily agrees well is — Cream f^ss. Milk fgiv. Sugar of milk 3j. Water fsiss. Should fever or disordered digestion occur during the period of prepara- tion, the number of artificial feedings must be reduced or the breast resumed until the disturbance be passed ; then the course may be begun again and car- ried to its completion. Sudden weaning is more difficult to accomplish, and is not advisable unless, while the breast is being presented, there is an absolute refusal to take artificial food, or unless the mother's health becomes so aff"ected as to render any further sucking a positive peril to the child's life : attacks of erysipelas or of small- pox are instances in point. The physician is often forced to decide upon the advisability of premature weaning. His decision must be made cautiously and after thorough investi- gation of two propositions — namely {a) the eff"ect of further lactation upon the health of the mother ; and (6) the requirements of the child. (a) Lactation, being a physiological process, is not a drain upon the sys- 20 AMEEIVA^^ TEXT-BOOK OF DISEASES OF CHILDEEX. temic strength so long as the functions of nutrition are actively performed, but under other circumstances it very frer^uently becomes so. Premature Vreaning is necessary Avhen the mother is attacked by any acute disease threatening dan- gerous temporary prostration, such as typhoid or typhus fever. A change must also be made if pulmonary consumption be developed, or, being already pres- ent, rapidly advances under the drain of milk-secretion. Usually, however, the general condition that leads to withdrawal of the breast is one of simple loss of strength and flesh on the part of the mother, and one which may often be overcome by attention to her health. If the trouble be merely diminished milk-secretion, it may often be reme- died by the free use of animal broths, chocolate, gruel, or milk, and some- times the moderate employment of stimulants, in the form of ale and porter, may be necessary. Such tonics as malt extract, ferrated elixir of cinchona, bitter wine of iron, and the preparation known as " beef, wine, and iron," are useful when there is aniemia or when the general failure of strength cannot be overcome by food and attention to hygienic rules. The ordinary local conditions indicating the necessity of premature wean- ing on the mother's account are fissures of the nipple and mammary abscess. {b) On the part of the infant there are several indications for premature weaning. It must be done if the occurrence of pregnancy or the recurrence of menstruation renders the milk unwholesome ; if the mother contract a dan- gerous contagious disease, as small-pox. scarlet fever, or erysipelas ; if the mammary glands become inflamed ; if the breast does not aiford suflficient nourishment and artificial food be refused ; and, finally, if dentition be mark- edly delayed and the premonitory symptoms of rickets appear. Upon deciding to anticipate the time of weaning, the next point to con- sider is whether the infant shall be brought up by hand or by a wet-nurse. 2d. Feeding by a Wet-nurse. — The advantage of this mode of feeding is that the mother's milk is substituted by the milk of ai^other woman ; in other words, that natural feeding is continued — a matter of moment in all cases, and of inestimable importance with delicate children. The disadvantage consists in the difficultv of findinor, in a woman belonGfing to the class from which wet- nurses come, all the moral and physical characters essential to a good substitute, and in the fact that a stranger is introduced into the household, often to deceive and annoy the family, and on the slightest provocation to le^ve her charge to fate or to the tender mercies of another of her kind. For these reasons it is preferable, in the majority of instances, to trust to careful bottle-feeding. Nevertheless, as some children must have human milk if their lives are to be saved, the rules for selecting a Avet-nurse must be understood. The woman chosen must be strong and robust, but rather spare than fat. Her bill of health must be perfectly free from hereditary tendency to mental or physical disease and from taint of syphilis, consumption, or scrofula. She must be cheerful, good-natured, active, careful, and temperate in habits. Her age should be between twenty and thirty years ; she shoitld understand the care of an infant and the manner of giving suck ; her child ought to be nearly of the same age as the infant to be adopted, and she must be able to aff'ord an abundant supply of good milk. The last quality can be estimated by inspect- ing the breasts, by examining some of the milk drawn by a pump, and by ascer- taining the condition of the woman's own child. The breasts of a good nurse are not necessarily large, but are firm to the touch and pyriform in shape, with well-developed, prominent nipples, and with the skin distinctly marbled with large blue veins. The milk, which ought to flow readily on pressure or on suction, should be opaque and dull white in color, have a specific gravity of GENERAL ^fANAGEMEXT OF CHILDREN. 21 1.031, an alkaline reaction, and show, when placed under the microscope, a number of minute, equal-sized fat-globules. Its quantity may be ascertained by weighing the child before and after sucking, the normal gain being from three to six ounces. There is, however, no better or more readily applied test of the quality of a nurse than the size, weight, and general development of her own child ; and if it be weak and ill-nourished, no amount of fitness in other respects can warrant her engagement. Even when a woman is found fulfilling in her single person all the required conditions — a rare thing, indeed — it does not necessarily follow that her milk will suit the babe to be suckled. Then changes and new trials must be made until the desired end be attained. 3d. Artificial Feeding. — There are many women who, no matter hoAv will- ing, are completely unable to suckle their babies, and a vast number in Avhom the secretion of milk fails after a few weeks or months of lactation. These must resort to a wet-nurse or to artificial feeding. Usually, they select the latter method. To ensure success in hand-feeding — always a difficult task — it is important to make a detailed study of the following questions : a, the selection of a proper substitute for the natural food — the breast-milk ; h, the quantity to be given : c, the method of preparation ; d, the mode of administration ; and, e, the means of preservation. a. Healthy breast-milk must be taken as the type of infants' food, and the nearer an artificial substance can be made to approach it in chemical composi- tion and physical properties the more perfect it is. Normal breast-milk has a specific gravity of 1.031. It is a persistently alkaline fluid, having a some- what animal, usually disagreeable, and, very rarely, sweetish taste. It is bluish-white in color and thin and watery in consistence. It contains nitro- genous material (caseine), carbohydrates (milk-sugar and fat), salts, and water — all the elements essential to repair tissue-waste, to supply new material for growth, and to maintain body heat, or, in other words, to constitute a perfect aliment ; and these, too, are so proportioned in the combination as to most easily and completely meet the demands. In seeking a substitute for human milk one naturally turns to the domestic animals for the source of supply ; cows' milk is usually selected, because, being plentiful, it is easily obtained and cheap. Cows' milk (market milk) has a lower specific gravity than human milk — namelv. 1.029 ; notwithstandincr this, it is richer-lookino; — that is, whiter and more opaque ; its reaction is slightly acid unless perfectly fresh from pasture- fed animals, when it may be neutral or alkaline. Its component ingredients are similar to those of human milk, but nitrogenous material exists in greater, the fat in somewhat less, and the sugar in far less proportion. The nitrogenous material also diifers in quality, containing a much larger proportion of albumin coagulable by acids. This difi'erence is readily tested by adding rennet to the two fluids. In the case of cows' milk the caseine is coagulated into large, firm masses, while with human milk a light, loose curd is formed. In the stomach the acid gastric juice has the same efi"ect, producing in the first instance a coag- ulum most difficult to digest ; in the other, one readily attacked and broken down by the gastro-intestinal solvents. These chemical and physical proper- ties of cows' milk can be altered by various methods of preparation, and unless this be done there are few instances in which it will not prove a poor substitute for the natural food. Condensed milk is frequently recommended by physicians, and largely used by the laity on their own responsibility. It keeps better than cows' milk, and is supposed to be more readily digested by young infants. The latter suppo- 22 AMEBIC AX TEXT- BO OK OF DISEASES OF CHILD BEN. sition is a mistaken one, and arises from the overlooked fact that condensed milk is always given dissolved in a large proportion of water, while cows' milk is too frequently used insufficiently diluted or otherwise improperly prepared. Condensed milk contains a large proportion of sugar, forms fat quickly, and thus makes large babies ; sugar also counteracts the tendency to constipation — often a troublesome complaint in hand-feeding. These advantages are unquestioned, and, together with the ease of preparation, are those which place it so high in the esteem of monthly nurses. It is equally true, however, that as a food it contains too much cane-sugar, and not enough nutrient material to supply the wants of a growing baby. Infants fed upon it, though fat, are pale, lethargic, and flabby ; although large, they are far from strong, have little power to resist diseases, often cut their teeth late, and are very liable to drift into rickets. It must be remembered also that condensed milk, when long kept or when packed in imperfect cans, not unfrequently undergoes decomposition, and thus becomes utterly unfit for use. For a temporary change of diet, however, and as a substitute during travelling or under cir- cumstances in which sound cows' milk cannot be obtained, it may be resorted to with advantage. The farinaceous substances so often selected, especially by the poor, to replace breast-milk, are not only bad foods, but have both directly and indirectly a delete- rious effect upon the processes of nutrition. They are bad for two reasons : First, they differ materially in chemical composition from human milk. For example, in arrowroot, which is the favorite, the proportion of the tissue-building to the heat-producing element is as one to twenty, while in human milk it is about one to five. Secondly, the heat-producing principle, starch, must be converted into sugar before it can be absorbed. This change is accomplished in the body by the saliva and pancreatic juice — secretions that are not fully established until the fourth month. While the starch lies undigested in the gastro-intes- tinal canal it is subject to fermentation, resulting in the formation of irritant products that rapidly induce catarrh of the mucous membrane — a condition directly interfering with the digestion and absorption of food. Again, perfect nutrition demands rapid waste and removal of effete tissues as well as repair of the same. This is effected by oxidation. iS^ow, sugars are known to have a much greater affinity for oxygen than albuminates, and when the diet con- sists of farinaceous material the small amount of sugar formed and absorbed appropriates oxygen that otherwise would go toward the removal of waste, and so retards the necessary changes. Farinaceous food, as such, is never permis- sible before the fourth month ; earlier, it is only to be employed for its mechan- ical action as an addition to milk preparations. This will be mentioned later. The nutrient value of the cereals and their products as they exist in so-called "infants' foods " has been imperfectly determined. They are undoubtedly use- ful as mechanical attenuants, but it is very questionable whether any of them, unless prepared with milk, can permanently meet the demands* of nutrition. At the same time, it is quite probable that the soluble albuminoid substances obtained by Liebig's process have a food value of their own, making them more serviceable than the starches. h. The quantity of food to be allowed each day varies with the appetite and age, and the question of the correct amount in a given case must be ansAvered by observation. Nevertheless, it is well to have some guide. (See table, page 24 et seq.) After the twelfth month the quantity depends upon whether additions be made to the diet or milk food be used exclusively. When the daily amount reaches three pints, the limit of the capacity of the stomach is usually attained, GENERAL MANAGEMENT OF CHILDREN. 23 and the greater demand for nutriment, as growth advances month by month, must be met by adding to the strength of the food rather than by increasing its bulk. These two factors, strength and quantity, are intimately associated throughout the whole period of infancy, and in the earlier months a mere increase in the latter is not always sufficient to maintain the balance of nutrition. c. The object to be accomplished in the preparation of cows' milk is to make it resemble human milk as much as possible in chemical composition and phys- ical properties. To do this it is necessary to reduce the proportion of caseine, to increase the proportion of fat and sugar, and to overcome the tendency of the caseine to coagulate into large, firm masses upon entering the stomach. Dilution with water is all that need be done to reduce the amount of caseine to the proper level ; but as this diminishes the already insufficient fat and sugar, it is essential to add these materials to the mixture of milk and water. Fat is best added in the form of cream, and of the sugars either pure white loaf sugar or sugar of milk may be used. The latter is greatly preferable, as it is little apt to ferment and contains some of the salts of milk, which are of nutritive value. Firm clotting may be prevented by the addition of an alkali or a small quantity of some thickening substance. Lime-water is the alkali usually selected. It acts by partially neutralizing the acid of the gastric juice, so that the caseine is coagulated gradually and in small masses, or passes, in great part, unchanged into the intestine, to be there digested by the alkaline secretions. As it contains only half a grain of lime to the fluidounce, the desired result cannot be attained unless at least a third part of the milk mix- ture be lime-water. Instead of lime-water, two to four grains of bicarbonate of sodium may be added to each bottle, or, better still, from five to fifteen drops of the saccharated solution of lime. This solution is made in the following way : Take of— Slaked lime 1 ounce. Refined sugar, in powder 2 ounces. Distiller^ water 1 pint. Mix the lime and sugar by trituration in a mortar. Transfer the mixture to a bottle containing the water, and, having closed this with a cork, shake it occasionally for a few hours. Finally, separate the clear solution with a siphon and keep it in a stoppered bottle- Thickening substances — attenuants, such as barley-water, gelatin, or one of the digestible prepared foods — act purely mechanically by getting, as it were, between the particles of caseine during coagulation, preventing their running together and forming a large, compact mass. To prepare the former, put two teaspoonfuls of washed pearl barley, with a pint of cold filtered water, into a saucepan ; boil slowly down to two-thirds and strain. The liquid ob- tained does not possess the disadvantages of farinaceous foods generally. To be efficient, it must be used as a diluent instead of, and in the same proportion as, water. Gelatin is prepared in the following way : Put a piece of plate gel- atin, an inch square, into a half-tumblerful of cold water, and let it stand for three hours ; then turn the whole into a teacup ; place this in a saucepan half full of water and boil until the gelatin is dissolved. When cold this forms a jelly; from one to two teaspoonfuls may be added to each bottle of milk food. When an- " infants' food " is used to act mechanically, care should be taken to select one in which the starch has been converted into dextrin and grape- sugar by the process of manufacture. 24 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN.

Instead of "infants' food," a teaspoonful of "flour-ball" may be added. To make flour-ball, take a pound of good wheat flour — unbolted, if possible ; tie it up very tightly in a strong pudding-bag ; place it in a saucepan of water and boil constantly for ten hours ; when cold, remove the cloth, cut away the soft, outer covering of dough that has been formed, and reduce the hard-baked interior by grating. In the yellowish-white powder obtained almost all the starch has been converted into dextrin by the process of cooking, and the proportion of the nitrogenous principle to the calorifacient is as one to five — nearly the same as human milk. Two meals of flour-ball daily — the second and fourth — are all that can be digested. To prepare these, I'ub one teaspoonful of the poAvder with a tablespoonful of milk into a smooth paste, then add a second tablespoon- ful of milk, constantly rubbing until a cream-like mixture is obtained. Pour this into eight ounces of hot milk, stirring well, and it is then ready for use. The other meals should be composed of milk, cream, sugar of milk, and water, as already given. Oatmeal or barley may also be used. GENERAL MANAGEMENT OF CHILDREN. 25 Diet for the tenth and eleventh months : First meal, 7 a. m. — Milk f iviiiss. Cream fgss. One of the Liebig foods 5ss.

On alternate days the third meal may consist of a teacupful (six fluidounces) of beef tea^ containing a few stale bread-crumbs. A further variation can be made by occasionally using mutton, chicken, or veal broth instead of beef tea. As much more difficulty is experienced in feeding infants during the first twelve months than during the second, it would be well to pause here to con- sider what had best be done in case the food described should disagree. If, after feeding, vomiting occur, with the expulsion of large, firm clots of caseine, the effect of adding lime-water or barley-water must be tried, both being added in the same quantity as the ordinary diluent — water. Sometimes, particularly if there be diarrhoea, boiling makes the milk more tolerable ; condensed milk, too, can be employed temporarily, making, for an infant of six weeks, each portion of — Condensed milk 5j. Cream f§ss. Hot water fgiiss. Should further alteration be necessary, goats' or asses' milk may be substi- tuted for cows' milk, the strong odor of the former and the laxative properties of the latter being removed by boiling. The milk should be used warm from the udder. " Strippings " is another good substitute for cows' milk. It is obta;ined by remilking the cow after the ordinary daily supply has been drawn, and con- tains much cream and but little curd. One part of strippings to two of water or an equal measure of barley-water makes an easil}^ digested mixture. The process of predigestion or peptonization enables us to overcome many of the difficulties encountered in bottle-feeding. Pancreatin is the agent to be employed. That manufactured under the name of extractum pancreatis by Fairchild Brothers & Foster of New York has proved most efficient in my hands. To accomplish artificial digestion put into a clean quart bottle five grains of extractum pancreatis, fifteen grains of bicarbonate of sodium, and four fluid- ounces of cool filtered water ; shake thoroughly together, and add a pint of fresh, cool milk. Place the bottle in water, not so hot but that the whole hand can be held in it for a minute without discomfort, and keep the bottle there for exactly thirty minutes. At the end of that time put the bottle on ice to check further digestion and to keep the milk from spoiling. The fluid obtained, while somewhat less white in color than milk, does not differ from it in taste : if, however, an acid be added, the caseine, instead of being coagu- ^ Beef tea for an infant is made in the following way: Half a pound of fresh rump-steak, free from fat, is cut into small pieces and put, with one pint of cold water, into a covered tin saucepan. This must stand by the side of the fire for four hours, then be allowed to simmer gently (never boil) for two hours, and, finally, be thoroughly skimmed to remove all grease. 26 AMEBIC AX TEXT- BOOK OF DISEASES OF CHILDBEX. lated into large, firm curds, takes the form of minute soft flakes or readily broken-down, feathery masses of small size. When the process is carried just to the point described, the caseine is only partly converted into peptone, but every succeeding moment of continued warmth lessens the amount of caseine until peptonization is complete. Then the liquid is grayish-yellow in color, has a distinctly bitter taste, and shows no coagulation whatever on the addition of an acid. ''Peptogenic milk powder," prepared by the same chemists, has given me even better results than the pancreatin and soda. This powder contains a digestive ferment, pancreatin ; an alkali, bicarbonate of sodium ; and a due proportion of milk-sugar. The mode of employment is as follows : Take of— Milk fBij. Water f^ij. Cream f Iss. Peptogenic milk powder 1 measure.^ This mixture is to be heated slowly to boiling, ten minutes being occupied, and then quickly cooled. When properly prepared the resultant, so-called "humanized milk," presents the albuminoids in a minutely coagulable and digestible form ; has an alkaline reaction ; contains the proper porportion of salts, milk-sugar, and fat ; is not bitter in taste, being but partially peptonized, and in appearance as well as chemical composition resembles human milk. The great advantages of partial peptonization are that the necessity for lime-water, barley-water, and thickening substances to keep apart the curd is done away with, and that, when the digestive disturbance requiring a careful preparation of food is removed, an ordinary milk diet can be gradually resumed by regularly diminishing the time artificial digestion is allowed to progress. This changes the caseine in a less and less degree, until, finally, it is taken in its natural form. " Sterilization," is another process of importance. As milk exists in the healthy cow's udder it is aseptic — ^. e. free from any poisonous or dangerous ingredient — but during milking and subsequent handling and transportation various foreign materials get into it and are apt to set up some inj urious change. To deprive these accidentally introduced organic impurities of their activity — or, in other words, to sterilize — it is necessary to subject the fluid to high heat under pressure. Several admirable implements have been devised for conducting the pro- cess ; one of the most simple, made after a design of my ow^n, is shown in This apparatus is made of tin, and consists of an oblong case provided with a well-fitting cover, and having a movable perforated false bottom (d), which stands a short distance above the true one and has attached a framework capa- ble of holding ten six-ounce nursing-bottles. On the outside of the case is a row of supports (b) for holding inverted bottles while drying, and at the proper distance below these a gradually inclining gutter (c) for carrying off" the drip. A movable water-bath (a) is hung to the side ; in this each bottle of food may be warmed at the time of administration. Ten graduated nursing-bottles are used, so that the whole supply of milk intended for a day's consumption can be prepared at once. Each bottle is provided with a perforated rubber cork, which in turn is closed by a well-fitting glass stopper. Sterilization should be performed in the morning as soon as possible after ^ Measure provided with each can of powder. GENERAL MANAGEMENT OF CHILDBEN. 27 the milk has been served. The process is as follows : First, see that the ten bottles are perfectly clean and dry ; pour into each six fluidounces of milk ; insert the. perforated rubber corks, without the glass stoppers, however; remove the false bottom and place the bottles in the frame ; pour into the Fig. 1. Author's Sterilizer. case enough water to fill it to the height of about two inches ; replace the false bottom carrying the bottles ; adjust lid and put the whole on the kitchen range. Allow the water to boil, and, by occasionally removing the lid. ascertain that the expansion that immediately precedes boiling has taken place in the milk ; then press the glass stoppers into the perforated corks, and thus hermetically close each bottle. After this keep the apparatus on the fire and the water boiling for twenty minutes. Finally, remove the false bottom with the bot- tles ; pour out the water, replace and carry the whole, covered with, the lid, to the nursery. Milk sterilized by this process will remain sound for many days : it is espe- cially useful in travelling, when fresh milk cannot be obtained ; for use in cities during the heat of summer, when milk is most apt to undergo injurious changes ; for a temporary change of food in delicate children or for those suffer- ing from disease of the stomach or intestinal canal. It must be remembered, however, that the prolonged heating produces certain changes in the compo- sition of the milk which make it more difiicult to digest, and that on this account many children do not thrive upon it. Another process of sterilization, suggested by Leeds, is free from this dis- advantage, and has proved most useful in my practice. It consists in heating the milk, rendered feebly alkaline with lime-water or sodium bicarbonate, to 155° F. for six minutes, or, better still, of applying the same amount of heat to milk with pancreatin and bicarbonate of sodium or with peptogenic milk powder. By the latter method the milk is both predigested and sterilized ; if not used at once, it must be momentarily heated to the boiling-point to check peptonization before the development of a bitter taste. According to Rowland G. Freeman, the problem that presents itself in the sterilization of milk for food is to devise a method which shall destroy by efiicient means the contained germs, and yet in the least possible degree interfere with its nutritive qualities. The experiments of Leeds show that 28 A3IEBICAN TEXT-BOOK OF DISEASES OF CHILDREN. sterilization at the boiling-point of water causes the following modifications : the starch-liquefying ferment is destroyed and coagulated ; caseine is rendered less coagulable by rennet, and is acted on slowly and imperfectly by pepsin and pancreatin ; protcid matters attach themselves to fat-globules, and prob- ably bring about a less perfect assimilation of fat ; while milk-sugar, by pro- longed heating, is completely destroyed. Koplik states that "from the temper- ature of 75° 0. upward there is a separation of the serum-albumin of the milk ; the caseine loses its coagulability to rennet, and at 85° C. amounts of rennet which for the raw condition of milk are fouitd sufficient to act cease to be effec- tive." Hueppe considers that from a physiological standpoint milk is best sterilized under a temperature of 75° C, while other experimenters have shown that temperatures lower than 100° C, if continued for a short time, will destroy a very large proportion of the germs, and will destroy with certainty many pathogenic germs which find their way into milk either from the cow or as external contaminations. Dr. Freeman, therefore, feels satisfied that Pasteurization offers the most rational solution of the question under consideration. The elaborate and recent experiments of Yersin, Granchier, Lidoux-Libard, and Bitter show that the bacillus tuberculosis in milk will be destroyed in ten minutes by an exposure to 75° C, in fifteen minutes to 70°, and in thirty minutes to 68°. Concerning other bacteria, Van Geuns found that a few seconds' exposure to 60° would kill the cholera spirilla, the Finkler-Prior bacillus, the typhoid bacillus, and the pneumococcus of Friedlander. It may, therefore, be concluded that a temperature of not less than 158° F. will render milk sufficiently germ-free for infant food, and that a temperature of less than 176° F. will not injure milk materially. Methods of Pasteurizing milk in bulk have been brought forward both in Germany and in this coun- try ; and now the procedure has been brought down to an easily-managed system for household use. This depends upon the theory that the tempera- ture of the milk to be treated may be raised to about the desired point (167° F.) by immersing a certain definite quantity of milk in a properly pro- portioned bulk of boiling water, the source of heat having been removed. The apparatus consists of two parts, a graduated pail for the water and a receptacle for the bottles of milk. This receptacle consists of a series of seven or ten hollow zinc cylinders fastened together, which fits into the pail containing the boiling water. Each of these cylinders is large enough to hold one of the bottles of milk, the series of seven cylinders accommodating seven eight-ounce bottles, and the series of ten cylinders being intended for ten six- ounce bottles. When the bottles are in place water is poured around them to secure perfect conduction of the heat. After the water in the pail is thor- oughly boiling, it is removed from the stove and placed on a non-conducting surface. The cylinders are now introduced, and the pail covered and left standing for thirty minutes, after which the milk is rapidly cooled in a refrig- erator or by cold water or ice and water. Milk thus treated and put imme- diately into a refrigerator usually shows no change for several days. Sometimes milk, in every form and however carefully prepared, ferments soon after being swallowed and excites vomiting, or causes great flatulence and discomfort, while it affords little nourishment. With these cases the best plan is to withhold milk entirely for a time and try some other form of food. The following are good substitutes : Veal broth (^ lb. of meat to the pint) f §iss. Barley-water f |iss. GENERAL MANAGEMENT OF CHILDREN. 29 Or, Whey f^iss. Barley-water f §iss. Milk-sugar 3ss. For one portion ; to be given every two hours at the age of two months. A teaspoonful of the juice of raw beef .every two hours will usually be retained when everything else is rejected. Such foods are only to be used temporarily until the tendency to fermentation within the alimentary canal ceases ; then milk may be gradually and cautiously resumed. When infants approaching the end of the first year become affected with indigestion, it is often sufficient to reduce the strength and quantity of the food to a point compatible with digestive powers. For instance, at eight months the food may be reduced to that proper for a healthy child of six months or even less. Here, too, predigestion of the food is very serviceable. If a few grains of extractum pancreatis be added to a gobletful of thick, well-boiled starch gruel at a temperature of 100° F., the gelatinous mucilage quickly grows thinner, and soon is transformed into a fluid, the starch having been rendered soluble by the action of the pancreatin ; by still longer contact the hydrated starch is converted into dextrin and sugar. Advantage may be taken of this property to render the foods containing starch assimilable. Thus, to a mixture of barley jelly and milk — e. g. Barley jelly Sjj, Milk sugar 3j, Warm milk f^viij, add three grains of extractum pancreatis and five grains of bicarbonate of sodium, and keep warm for half an hour before administering. The same process may be employed with food containing oatmeal, arrow- root, or wheaten flour, or in the case of meat broths, with a view of converting the starchy and albuminoid ingredients into digestible elements without mate- rially altering the taste. Returning to the regimen of the healthy infant, it will be found that after the first year far less change is required in the food from month to month. Diet from the twelfth to the eighteenth month, five meals per day : First meal, 7 a. m. — a slice of stale bread, broken and soaked in a breakfast-cup (eight fluidounces) of new milk. Second meal, 10 A. M. — a teacup of milk (six fluidounces), with a soda biscuit or thin slice of buttered bread. Third meal, 2 p. m. — a teacup of beef tea (six fluidounces), with a slice of bread ; one good tablespoonfal of rice-and-milk pudding. Fourth meal, 6 P. M. — same as first. Fifth meal, 10 p. M. — one tablespoonful of Mellin's Food, with a breakfast-cupful of milk. To alternate with this : First meal, 7 A. M. — the yelk of an egg lightly boiled, with bread-crumbs ; a teacupful of new milk. Second meal, 10 A. M. — a teacupful of milk, with a thin slice of buttered bread. Third meal, 2 p. M. — a mashed baked potato, moistened with four tablespoonfuls of beef tea ; two good tablespoonfuls of junket. Fourth meal, 6 p. m. — a breakfast-cupful of new milk, with a slice of bread broken up and soaked in it. Fifth meal, 10 P. M. — same as second. The fifth meal is often unnecessary, and sleep should never be disturbed for it ; at the same time, should the child awake an hour or more before the first meal, he must break his fast upon a cup of warm milk, and not be allowed to go hungry until the set breakfast hour. Diet from eighteen months to the end of two and a half years, four meals 30 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. a day : First meal. 7 a. M. — a breakfast-cupful of new milk ; the yelk of an ecfg lightly boiled; two thin slices of bread and butter. Second meal, 11 a. m. — a teacupful of milk, with a soda biscuit. Third meal. 2 P. M. — a breakfast- cupful of beef tea, mutton or chicken broth ; a thin slice of stale bread : a saucer of rice-and-milk pudding. Fourth meal, 6.30 p. M. — a breakfast-cupful of milk, with bread and butter. On alternate days : First meal, 7 a. m. — two tablespoonfuls of thoroughly cooked oatmeal or wheaten grits, with sugar and cream ; a teacupful of new milk. Second meal, 11 a, m. — a teacupful of milk, with a slice of bread and butter. Third meal, 2 p. m. — one tablespoonful of underdone mutton pounded to a paste ; bread and butter, or mashed baked potato moistened with good plain dish gravy ; a saucer of junket. Fourth meal, 6.30 P. M. — a breakfast- cupful of milk, a slice of soft milk toast or a slice or two of bread and butter. AVhen sickness supervenes, all that is ordinarily necessary is a reduction of the diet to plain milk or some easily digestible milk mixture. An important point, often neglected, is the matter of drink. Even the youngest infont requires water several times daily, and the demand increases with age. The water must be as pure as possible, and should not be too cold. In the heat of summer, however, bits of ice and water moderately cooled by ice can be allowed without harm. The foregoing schedule must, of course, be regarded only as an average. Many children can bear nothing but milk food up to the age of two or even three years, and, provided enough be taken, no fear for their nutrition need be entertained. If a child be thriving on milk, he is never to be forced to take additional food merely because a certain age has been reached ; let the healthy appetite be the guide. d. Success in hand-feeding depends quite as much on the administration as upon the preparation of the food. From birth up to such time as broth, bread, and eggs are added to the diet all the food should be taken from a bottle. Even after this, as the bottle is a comfort and ensures slow feeding, it may be allowed for milk preparations until the child, of his own accord, tires of it. The only feeding apparatus to be admitted to the nursery is the simple bottle and tip. The bottle made after mv sucrfrestion. and known as the ''trraduated nursing-bottle," has an interior surface free from angles, so that it is readily kept clean, and is provided with a scale for the measurement of ounces and half-ounces. It is made of ti'ans- parent flint glass, so that the slightest foulness can be detected at a glance, and may vary in capacity from six to twelve fluidounces according to the age of the child. Two should be on hand at a time, to be used alternately. Im- mediately after a meal the bottle must be thoroughly washed out with scalding water, filled with a solution of bicarbonate or salicylate of sodium — one tea- spoonful of either to a pint of water — and thus allowed to stand until next required : then, the soda solution being emptied, it must be thoroughly rinsed with cold water before receiving the food. The tips or nipples, of which there should also be two, must be composed of soft, flexible India-rubber, and a con- ical shape is to be preferred, as being more readily everted and cleaned : the opening at the point must be free, but not large enough to permit the milk to flow in a stream without suction. At the end of each feeding the nipple must be removed at once from the bottle, cleansed externally by rubbing with a stifi" brush wet with cold water, everted and treated in the same way, and then placed in cold water and allowed to stand in a cool place until again wanted. Next to cleanliness of the feeding apparatus it is important to insist upon the separate preparation of each meal immediately before it is to be given. The GENERAL MANAGEMENT OF CHILDREN 31 practice of making, in the morning, the whole day's supply of food, though it saves trouble, is a most dangerous one. Changes almost invariably take place in the mixture, and by the close of the day it becomes unfit for consumption. The food must be administered at a temperature of about 95° F. It may be heated by steeprng the bottle containing the food in hot water or by placing it in a water-bath over an alcohol lamp or gas-jet. When feeding, the ohild must occupy a half-reclining position in the nurse's lap. The bottle should be held by the nurse, at first horizontally, but gradu- ally more and more tilted up as it is emptied, the object being to keep the neck always full and prevent the drawing in and swallowing of air. Ample time — say five, ten, or fifteen minutes, according to the quantity of food — should be allowed for the meal. It is best to withdraw the bottle occasionally for a brief rest, and after the meal is over sucking from the empty bottle must not be allowed, even for a moment. e. For children residing in cities an honest dairyman must be found who will serve sound milk and cream from country cows once every day in winter, and twice during the day in the heat of summer. The milk of ordinary stock cows is more suitable than that from Alderney or Durham breed, as the latter is too. rich, and therefore more difficult to digest. The mixed milk of a good herd is to be preferred to that from a single animal : it is less likely to be affected by peculiarities of feeding, and less liable to variation from alterations in health or different stages of lactation. The care of the herd and of the milk is of great consequence. The cows should be healthy, and the milk of any animal that seems indisposed should be excluded. The cows must not be fed upon swill or the refuse of breweries, glucose-factories, or any other fermented food. They must not be allowed to drink stagnant water, and must not be heated or worried before being milked. The pasture must be free from noxious weeds, and the barn and yard must be kept clean. The udder should be washed, if dirty, before the milking. The milk must be at once thoroughly cooled. This is best accomplished by placing the can in a tank of cold spring-water or in ice- water, the water being the same depth as the milk in the can. It is well to keep the water in the tank flowing; indeed, this is necefcsary unless ice-water be used. The can should remain uncovered during the cooling, and the milk should be gently stirred. The temperature should be reduced to 60° F. within an hour, and the can must remain in the cold water until the time for delivering. In summer, when ready for delivery, the top should be placed in position and a cloth wet in cold water spread over the can, or refrigerator cans may be used. At no season should the milk be frozen, and at the same time no buyer should receive milk having a temperature over 65° F. For transportation from the dairy it is safer for the family to provide two sets of small cans — one set to be thoroughly cleansed and aired, while the other is taken away by the milkman to bring back the next supply. So soon as this arrives in the morning, or in the morning and evening in hot weather, the milk should be emptied into separate and absolutely clean earthenware or glass pitch- ers, and these put at once into a refrigerator reserved exclusively for them. This may stand in some convenient spot near the nursery, but not in it, and especially not in an adjoining bath-room. With a good refrigerator there is no difficulty in keeping milk perfectly sweet for twenty-four hours in winter and for twelve hours in summer, except on intensely hot days ; then it may be necessary to scald, slightly boil, or sterilize the whole of the supply when received, in order to prevent change. Childhood. — Children who have cut their milk teeth may be fed for a 32 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. twelvemonth — namely, up to the age of three and a half years — in the follow- ing way : First meal, 7 A. M. — one or two tumblerfuls of milk, a saucer of thoroughly cooked oatmeal or wheaten grits, and a slice of bread and butter. Second meal, 11 a. m. (if hungry) — a tumblerful of milk or a teacupful of beef tea with a biscuit. Third meal, 2 P. M. — a slice of underdone roast beef or mutton or a bit of roast chicken or turkey, minced as fine as possible ; a baked potato thoroughly mashed with a fork and moistened with gi'avy ; a slice of bread and butter; a saucer of junket or rice-and-milk pudding. Fourth meal, 7 p. m. — a tumblerful of milk and one or two slices of well-moistened milk toast. From three and a half years up the child must take his meals at the table with his parents, or with some reliable attendant who will see that he eats leisurely. The diet, while plain, must be varied. The following list will give an idea of the food to be selected : BREAKFAST. Every Day. One Dish only Each Day. Milk. Fresh fish. Eggs, plain omelette. Porridge and cream. Eggs, lightly boiled. Chicken hash. Bread and butter. " poached. Slewed kidney. " scrambled. " liver. Sound fruits may be allowed before and after the meal, according to taste, as oranges, wiihoiit pulp, grapes (seeds not to be swallowed), peaches, thoroughly ripe peai-s, and cantaloupes. DINNER. Every Day. Two Dishes Each Day. Clear soup. Potatoes, baked. Hominy. Meat, roasted or broiled, " mashed. Macaroni, plain. and cut into small Spinach. Peas. pieces. Stewed celery. String-beans, young. Bread and butter. Cauliflower. . Green com, grated. Junket, rice-and-milk, or other light pudding, and occasionally ice cream, may be allowed for desert. SUPPER. Every Day. Milk. Milk toast or bread and butter. Stewed fruit. Fried food, highly seasoned or made-up dishes are to be excluded, and no condiment but salt is to be used. Eating, hoAvever little, between meals must be absolutely avoided. Keep a young child from knowing the taste of cakes or bonbons, or, having learned it, let him feel that they are as unattainable as the thousand other things beyond his reach, and he soon ceases to ask for them. Even a piece of bread between meals should be forbidden. His appetite then remains natural, and he will eat proper food at his regular meal hours. As to the quantity, a healthy child may be permitted to satisfy his appetite at each meal, under the one condition that he eats slowly and masti- cates thoroughly. Filtered or spring water should be the only drink, tea, coifee, wine, or beer being entirely forbidden. In case of illness the diet must be reduced in quantity and quality, accord- ing to the rules that are applicable to adults. 2. Bathing. Durinof the first two and a half years of life a child ouwht to be bathed once every day. The bath should be given at a regular time, and it is best to GENERAL MANAGEMENT OF CHILDREN. 33 select some hour in the early morning, midway between two meals — ten o'clock, for instance. The tub should be placed near the fire or in a warm room in winter, and away from currents of air in summer. It should contain enough water to cover the child up to the neck when in a sitting posture, and the temperature must be about 95° F. Upon undressing the child the first step is to wet his head ; then he is to be plunged into the water and thoroughly washed with a soft rag or sponge and pure, unscented castile soap. After remaining in the water from three to five minutes the surface must be well dried and rubbed with a flannel cloth or soft towel ; then the body must be enveloped in a light blanket and the infant either returned to his crib to sleep or kept in the lap for ten or fifteen minutes until thoroughly warm and rested, and finally dressed. If there be repugnance to the bath, the tub may be covered over with a blanket, and the child, being placed upon it, may be slowly lowered into the water with- out seeing anything to excite his fears. In very hot weather, in addition to the morning full bath, the body may be sponged twice daily with water at a temperature of 90° F. ; this, contrary to what might be expected, has a greater and more permanent cooling eff'ect than bathing with cold water. After the third year three baths a week are quite sufiicient. An evening hour is now to be preferred, but the Avater must still be heated to 90°. About the tenth year cooler baths can be begun, from 72° to 75° being the proper temperature. The cold sponge or cold plunge is not admissible as a daily routine until youth is well advanced. The hot bath — 95° to 100° F-. — is employed for various purposes, notably for a derivative action, to cause diaphoresis, to relieve nervous irritability, and to promote sleep. Whether a full bath or merely a foot-bath be required, five minutes is a sufiicient time for immersion ; then, with or without drying, according to the degree of sweating desirable, the whole body, or only the feet and legs in case of a foot-bath, must be enveloped in a blanket, and the child put to bed. To render these baths more stimulating, from a teaspoonful to a tablespoonful of mustard flour may be added, and the child held in the water until the arms of the nurse begin to tingle. It is important not to con- tinue a hot bath too long, lest the primary stimulating efi'ect be followed by depression. Cold baths, by shocking the system, first produce depression ; but this is temporary and is followed by reaction, during which the skin grows red and the pulse becomes fuller and stronger. They have, therefore, a general stimu- lant and tonic action, promoting nutrition and giving tone to the body. On account of the shock, the extent of which depends directly upon the coldness of the water, these baths must be used with caution, and are not to be employed in very young or feeble subjects. When giving a cold bath, the child must be stripped in a warm room, and thoroughly rubbed with the palm of the hand until the whole body, especially the spinal region, is reddened ; he must then stand in a tub containing enough hot water to cover the feet, and be rapidly sponged with the cold water. The temperature of the latter must never be below 60°, and the addition of half an ounce of sea-salt or a tablespoonful of concentrated sea-water to the gallon renders it more stimulating and ensures a complete reaction. After the sponging the surface must be thoroughly and quickly dried with a soft towel and shampooed with the open hand\ntil aglow. The cooled bath may be employed with advantage in extreme conditions of hyperpyrexia. The child is first immersed in water at 95°, and this is gradually lowered to 70° by the addition of cold water, the process occupying from fifteen to thirty minutes. 34 AMERICAN TEXT-BOOK OF J)ISEASES OF CHILDREN. 3. Clothing. Infants and yoiin^ children have little power of resisting cold, and on this account require warm clothing. The condemnation of the fashion of allowing children to go, even while in the house, with bare legs and knees must be absolute. Occasionally during the most oppresive heat of a summer midday the legs may be left uncovei'ed ; but with this exception the rule is to keep the whole body encased in woollen underclothing. The thickness of this must vary, of course, with the season. Providing this be done, the outer clothing may be left to the taste of the mother ; but all garments should fit loosely, that the functions of the different viscera may not be impeded by pressure. The best pattern of a winter night-dress is a long, plain slip, with a draw- ing-string at the bottom, to prevent exposure of the feet and limbs should the child kick off" the bed-covering. This should be made of flannel or the more easily w-ashed canton flannel. Jn summer a loose muslin one may be put on, without the drawing-string. A flannel under-vest should always be worn at night, light gauze in summer and heavier wool in winter; care must be taken, however, to have one for night alone, discarding that worn in the daytime. In infants under a year old a broad flannel abdominal bandage, extending from, the hips Avell up to the thorax, or, Itetter still, a knitted worsted band shaped to fit the form, is very useful in keeping the abdominal organs warm, aiding digestion and preventing pain. All clothing should be changed sufficiently frequently to ensure cleanliness. Shoes must be large, well shaped, and made of soft leather with pliable soles, so as to allow the feet to grow freely. When dressing a child for exercise in the open air in cold weather, the outer clothing must not be put on until just before leaving the house, and removed immediately on return. It is important to protect the head from cold in winter by a close-fitting, thick cap, and from the direct rays of the sun in summer by a broad-brimmed, light straw hat. Rubber shoes are necessary in wet weather to keep the feet warm and dry while walking out of doors. 4. Sleep. For some time after birth infants spend the intervals between being fed, washed, and dressed, in sleep, and thus pass fully eighteen out of the twenty- four hours. As age advances the amount of sleep required becomes less, until at two years thirteen hours, and at three years eleven houi^s, are enough. This matter, though, is perhaps more a question of training than any other item of nursery regimen, and one cannot too soon begin to form the good habit of regularity in sleeping hours. So far as circumstances will admit, the follow- ing rules may be enforced : From birth to the end of the sixth or eighth month the infimt must sleep from 11 P. M. to 5 A. M., and as many hours during the day as nature demands and the exigencies of feeding, washing, and dressing will permit. From eight months to the end of two and a half years a morning nap should be taken from 12 M. to 1.30 or 2 p. m., the child being undressed and put to bed. The night's rest must begin at 7 P. M. If a late meal be required, the child can be taken up at about ten o'clock ; but if past the age for this, he may sleep undisturbed until he wakes of his own accord some time between 6 and 8 a. m. From two and a half to four years, an hour's sleep may or may not be taken in the morn- ing, according to the disposition of the subject; but in every case the bed must be occupied from 7.30 P. M. to 6 or 7 o'clock on the following morning. After the fourth year few children will sleep in the daytime ; they are ready for GENERAL REMARKS ON TREATMENT. 35 bed by 8 p. m., and should be allowed to sleep for ten hours or more. A later retiring hour than 9 p. M. ought not to be encouraged until after the twelfth or fifteenth year. When feasible, different rooms should be used for the day nursery and the sleeping apartment. If an apartment has to be occupied during both the day and night, it must be vacated for half an hour or more in the evening and well aired before the child is put to bed. The temperature of the room must be as uniform as possible, the proper degree of heat being from 64° to 68° F. 5. Exercise. A certain amount of muscular exercise is necessary for development and for the proper performance of the digestive functions. Infants before they are able to stand will use their muscles sufficiently if, when loosely clad, they are placed upon their backs in a bed and allowed to kick and turn about at pleas- ure. After the age of nine or ten months a healthy child will begin to creep ; at the end of a year he will make efforts at standing, and from four to eight months later will be able to walk by himself; children, however, present great differences in this respect, and a delay of a few months must not be considered as abnormal. So soon as efforts at creeping are made there need be no fear that insufficient exercise Avill be taken ; the care should be rather to prevent over-fatigue. Fresh air and sunlight are as necessary as muscular exercise. The child must be taken out of doors every day, weather permitting, after arriving at the proper age : this is four months for children born in the early fall and winter, and one month for those born in summer. In cool weather babies who are unable to walk should be taken out in a coach or in the nurse's arms for an hour in the morning and half an hour in the afternoon, while the sun is shining. In summer they may pass the greater part of the waking hours in the open air, provided they be well protected from the direct rays of the sun. Children old enough to walk may spend a longer time in the air in winter, and may be out all day in summer. But until the fourth year it is better to let them play about at will than take a long set walk. Until well advanced in childhood the house is the safest place in damp and rainy weather, when there is a strong east or north wind blowing, and when the thermom- eter stands below 15° F. rn. General Remarks on Treatment. It is difficult to formulate a precise, reliable, or handy posological table ; in fact, the whole matter of dosage for children is one of experience, and with practice every one makes his own dose-list in his mind, and the proper amount of a given drug for a given age requires as little effort of memory as in the case of adults. Nevertheless, as a guide to the student. Cowling's rule is serviceable — namely, the proportionate dose for any age under adult life is represented by the number of the following birthday divided by 24 — i. e. for one year, -2^4 = xV ' ^*^^ ^^^ years, ^-^ ^^\'i and so on. All powerful drugs must be given with caution to children, but opium rie- quires the greatest care. Infants bear it only in infinitesimal proportions, and in these its use is to be avoided as much as possible ; still, combined with cas- tor oil, it is a useful drug in bad cases of flatulent colic, the average commen- cing dose in the first six weeks of life being not more tha HI 3V of the tincturen (laudanum). After the second or third month the extreme susceptibility to the drug disappears, and ITl^ of laudanum may be given for a dose. 36 AJIIJBICA^' TEXT-BOOK OF DISEASES OF CHILDREN. Bromide of potassium, a most valuable remedy in many diseases, must be given to infants with watclifuluess, as it sometimes, even in small doses, pro- duces severe local inflammations of the skin and localized patches of soft, warty growths. Belladonna and arsenic are illustrations of an opposite tendency, for chil- dren ai*e very tolerant of these drugs, particularly the first. A child of four or five years can readily take from two to five minims of tincture of bella- donna, and in cases in which it is necessary to administer arsenic to choreic children of six years and upward a commencing dose of five minims of Fow- ler's solution may often be given three times daily, and a considerable increase in this be attained if required. Such initial doses are, however, occasionally productive of the symptoms of mild arsenical poisoning, and therefore it is well to begin with one- or two-minim doses and increase rapidly. This rule applies especially to children belonging to the wealthier classes, for these, like their parents, are much more sensitive to drugs than hospital patients — an undoubted physiological fact of wide bearing. Alcohol is frequently indicated and is of great value, but it must be used with judgment. It is most useful in broncho-pneumonia, severe febrile condi- tions ; in the prostration fallowing measles, diphtheria, and whooping cough ; and in the collapse that frequently attends severe thoracic or abdominal disease. All drugs should be made as palatable as possible. In conclusion, it must be remembered that children do not often require energetic treatment with drugs. Proper feeding and hygiene are of most importance in the management of disease in early life. THE CHEMISTRY OF MILK AIN^D OF ARTIFICIAL FOODS FOR CHILDREN. By albert R. LEEDS, Ph. D., HOBOKEX. I, The Chemistry of Milk. The peculiar adaptation of milk to the feeding of the young depends upon its unique combination of chemical and physical properties. It contains in well-balanced proportions the three essential elements of nutrition — the nitrog- enous, or tissue-building ; the carbohydrate, or heat-giving ; and the fats. Along with these are a sufficiency of saline substances to carry on the chemical metamorphoses of cell-formation, of secretion and excretion, and an ample supply of water as the universal solvent. These substances are held partly in a state of solution, partly in a state of semi-solution, conferring upon milk its slightly colloidal consistency, and partly in suspension, producing its appear- ance of density and opacity. But it contains no waste material like the indi- gestible fibre and cellulose of flesh, fruit, and vegetables. Neither does it exhibit a development of one or two elements of nutrition at the expense of the third, as is the case with all other foods, — even eggs, which most nearly approach milk in this respect, not being excepted. Finally, almost no prepara- tion before, during, or after swallowing is requisite for the absorption of milk through the rudimentary digestive apparatus of the young. The chemistry of woman's milk can be well and effectively studied for our present purposes only in connection with that of cow's milk. For at the very outset a peculiar difficulty is experienced in attempting to procure a sample of the former, which does not exist in the case of the latter. Some sort of a breast-pump or similar appliance must be used, and this unnatural process yields at the best but a partial sample. This fact explains many of the great and anomalous variations exhibited in the analyses. It also renders the con- clusions drawn from an isolated analysis of little value; and in practice it is wiser to base any conclusions as to the sufficiency and quality of the breast- milk upon the condition and yield of the gland, upon the physical condition and nutrition of the mother, and, most of all, upon the development of the child and its deportment in nursing. On the other hand, innumerable analyses of complete samples of cow's milk exist, embracing every variety of breed, under every condition of climate, age, culture, and feeding. Cow's Milk. — On no other article of food has such elaborate care been expended, both as to its production and chemical investigation. Most civilized communities have enacted laws to protect its purity, and recognize no evidence in courts of law except when substantiated by adequate chemical testimony. 37 38 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Similar investigations are being constantly made with a view of so adjusting the feeding and the breed as to obtain the largest quantity of milk or the greatest richness, or both. Beginning with cattle of small, imperfectly- developed udders, the cow has become through generations of culture the incom- parable milk-secreting animal of modern nations, and has so far displaced the ass, goat, mare, and others that it is useless to consider their milk as an avail- able substitute. For similar reasons, the cow's milk which must be considered from the standpoint of general dietetics is such sound, Avhole country milk as is ordi- narily supplied by reputable dealers. It is useless to quote the analyses of the milk of Alderney, Jersey, and Guernsey cattle, obtainable only by the few ; and when obtained, such milk, with its higher percentage of proteids and its greater liability to variation from idiosyncrasy in condition or health of indi- vidual cattle, is not to be preferred over that of the average milk of large herds properly bottled before being sent to market. So likewise as to the com- position of the '' strippings " of the udder. They are not usually procurable, and their greater richness in fat and deficiency in casein can be better arrived at, even when ordinary whole milk is used, by appropriately modifying its composition. Limiting our consideration strictly to commercial bottled milk, it becomes of the greatest importance to inquire into the present conditions regulating its production and handling at the farm, during transit, and in delii^ery to the con- sumer. Hitherto, these conditions have fallen far short of the requirements which chemical and medical science should rightly impose upon milk as the prime article of artificial infant nutrition. The State laws have checked the adulteration of milk by addition of water and removal of cream, but as yet have done little, and that only incidentally, in the way of guaranteeing its wholesomeness and improving its quality. In fact, enlightened public senti- ment, assisted and directed by the medical profession, will do more in this direction than can be expected at present from the State. And the same remark is true of the efforts of the dairyman. AVhat is being done and should be done is best exemplified by a recital of the provisions of a legal contract drawn up between a committee of certain medical societies in the vicinity of New York on the one hand and a competent dairyman on the other. The latter undertakes that his herd of Holstein and Jersey cattle shall be regularly and frequently inspected by a veterinarian selected by the committee and paid by the dairyman. All cattle that are pronounced by the surgeon, for any cause whatsoever, disqualified to produce pure sound njilk are forthwith excluded from the herd. Interbreeding more frequently than the fourth generation is interdicted. The cattle must be kept in a large, well-ventilated, well-lighted stable, Avith ample space and no overcrowding, with abundance of pure water for drinking and cleansing ; with perfect drainage ; with dry cemented floors ; with clean fresh l)edding of hav ; and with arrangements for securing them in the stall which shall give ample liberty to the movements of the head and for lying down, but shall do away with the necessity of chains or other fastening. Separate stalls and partitions, as interfering with ventilation and cleanliness, are done away with. The cow-stables must be removed from those in which horseSj chickens, and other stock are kept by so great a distance that the cattle can in no wise come in contact with the other animals. The cows must be groomed daily, and the teats Avashed before each milking. The milkmen must perform their own toilets before milking, being especially required to thor- oughly cleanse their hands and to remove the dirt beneath the finger-nails, Avear- ing also unsoiled clothing. The feeding is to be regulated by the season in such CHEMISTRY OF MILK AXD ARTIFICIAL FOODS. 39 wise that the milk produced shall conform to the highest feasible standard of excellence. Abundance of wholesome pasture, hay, meal, fodder, and ensilage is demanded, but the refuse of glucose-factories, brewers' grains, swill in any form, etc. are interdicted. There are also provisions in the contract that the cattle shall not be worried, heated, or driven, or milked except after proper interval after calving. The milking must be done with scrupulously cleansed vessels ; the milk filtered through fine metallic gauze, then cooled in a dust- free atmosphere in such Avise as to lower the temperature as rapidly as possible, and also to permit the escape of the gases along with the animal heat ; and, finally, transferred to bottles rendered as nearly sterile by cleansing with boil- ing water and steam as possible. These jars, which must be entirely full, are closed by a metallic cover, sealed, transferred to boxes with a layer of ice on top of them, and delivered at an early hour in the day, the temperature of the milk never being allowed to rise in the interval above 50° F. The dairyman further undertakes to pay for the services of a competent chemist and biologist, who shall frequently test the milk, and whose analyses and certificates shall accompany it. He also undertakes to have his stables, cattle, feed, bottling arrangements, etc. open at all proper times to inspection, and to comply with all other requirements of the committee which they in their judgment shall deem essential to securing the highest attainable degree of quality and purity. The only obligation which the committee assumes is that it permits the milk to be sealed with a label bearing the name of the dairy and the dairyman, and the legend " Certified Milk," and to be accompanied by the certificate of purity bearing the name of the committee, the chemist, biologist, and veterinarian. Milk in the human gland or cow's udder, when tuberculosis or kindred dis- ease is absent, contains no bacteria. Indeed, by rejecting the first portions and excluding floating particles in the air, sterile cow's milk can be obtained, and contrivances to this end have been patented ; but they are quite imprac- ticable. So likewise is the proposition to sterilize all the milk before it leaves the farm by heating it at 230° F. for a sufficient length of time completely to destroy every spore which might by any possibility be present. Consumers would not pay for the skill, time, and apparatus required, and the process itself produces unfavorable changes in the milk. The first portion of this objection applies also to the proposition that the milking should be done directly into sterilized bottles, and the milk then Pasteurized by heating to a temperature of 160°— 170° for twenty minutes. Any of the bacteria present in the air. water, ground, or derived from the diseased or filthv condition of those who handle the milk at anv time, or arising from the animals themselves, may possibly find their way into milk. And, inas- much, as this fluid is an excellent culture-medium, they multiply with great rapidity. But these things demand suitable care for their prevention, and not a care involving the compulsory sterilization of all milk. The author believes that no more should be required of the dairyman than the reasonable precau- tions above detailed, which self-interest also demands. Then a false security will not be placed in legal requirements sure to be evaded or neglected, and necessitating an army of skilled inspectors, veterinarians, and chemists to enforce. The few ounces of milk needed for artificial nursing are best sterilized immediately before use, and this is best done in the course of the preparation essential to adapt it for infant feeding, either just before transfer to the bottle or in the bottle itself. By so doing, the fact, usually lost sight of, will be kept constantly in mind — that the same precautions as to the bottle, nipple, the water used, the exclusion of floating particles from the milk, and the keeping of it in a refrigerator are as essential to preserving the sterility of the milk as 40 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. its sterilization in the first instance. Washing in boiling water cannot be trusted to remove the adherent skin of fat and casein on the milk- vessels ; some soda must be used; the rubber nipple should be turned inside out over the finger and scrubbed with a brush and precipitated chalk. Supposing that the present enlightened public sentiment has secured such a legalized system of sanitary cattle-inspection and milk-control, as to make the reasonable precautions now exercised voluntarily by honorable dairymen obligatory upon all, bottled milk, Avhich I shall term "sound dairy milk," presents the folloAving characteristics : In color it varies from white to yelloAV. Even when allowed to fall in drops from the end of a rod it exhibits a dense white opacity and consistency, the fluidity and bluish-white color of watered or inferior milk being absent. It is almost neutral, reddening litmus-paper very feebly. On standing, the cream rises in the neck of the quart bottle com- monly used until it forms a layer about two and a half inches in depth. These physical characters are all that need be noted. If they are absent, if the milk is thin and watery, if it has a bluish, blue, strong yellow, or red color, if it is stringy, lumpy, or glutinous, if it has a flat, stale, sour, or any abnormal taste or odor, — it is simply to be rejected, and its investigation left to the milk inspector and chemist. Many analyses of such bottled milk afford me the following average results, which are given as preliminary to the still better figures that will come with "certified milk:" Fats 3.75 per cent. Lactose (milk-sugar) 4.42 " Albuminoids 3.76 " Ash 0.68 " Total solids 12.61 per cent. In some of the States the legal standard calls for 12.5 per cent, of total solids and 3 per cent, of fat. It is much to be deplored that in other States, as in New Jersey, the standard demands only 12 per cent., and unless the fat falls below 2| the milk is assumed to be unskimmed. It was made thus low in order that no lack of care in housing and cleanliness, no inadequacy of feed- ing, no abstraction of cream from the evening milk (half-skimming), and no accidental or judicious watering should bring the owner or vendor under con- demnation of laAv. For the same reasons it is assumed that any milk which has a higher specific gravity than 1.029 at 60° F. (100° on the lactometer scale) is pure, whereas the average of sound dairy milk should be 1.0297. Human Milk. — Having given the above general characteristics of cow's milk, it is necessary to do the same for human milk, and then proceed to a more specific comparison of their resemblances and differences. And in the first place, while all the conditions and environment are arranged to develop the milk-secreting function of milch cattle, in the human family, on the other hand, they are more and more ignored as Avomen become burdened with the increasing duties and dissipations of modern society. The regular life with moderate enjoyments, exercise, and occupation, the simple nourishing diet, with abundance of fresh air and rest, which are most favorable to the milk- secretion, are sacrificed, with the result of arresting or diminishing the floAV and deteriorating the quality of the milk. Stimulants, narcotics, improper or highly-seasoned food, functional disorders with their attendant medicines, violent emotions and paroxysms of grief, anger, and pain, render the milk unAvholesome and sometimes dangerous. As a contribution to the chemistry CHEMISTRY OF MILK AND ARTIFICIAL FOODS. 41 of this subject I give in an accompanying table the results of 80 analyses of samples of milk obtained from women of different nationalities, age, stage of lactation, and physical constitution, but all living in a lying-in hospital under the same conditions and eating the same food. (See pp. 42 and 43.) The analvses are arranged according to the period of lactation, except in cases where several samples were taken, these following consecutively. Many hundred analyses would be required to determine what differences, if any, are due to nationality or to the physical characteristics of the mothei- — whether black, blonde, or brunette, or, more minutely, the color of the eyes, hair, com- plexion, etc. But the influence of the physical condition was pronounced, the best milk not coming from women of robust habit (Column I.), but from those whose nourishment appeared rather in the milk-secretion than in the fattening of the mother (Column II.) : I. (6 cases). II. (6 cases.) Fats 3.71 .... 3.96 ' Lactose 6.94 .... 6.74 Albuminoids ' 1.44 .... 2.12 Ash 0.25 .... 0.22 Total solids 12.34 .... 13.04 The reaction of every sample was alkaline, the alkaline reaction persisting during one or more days. The color varied from bluish-white through chalky- white to strong yellow, but the color was not a necessary index of the compo- sition : the milk of a (jrerman(No. 34), which was the richest in fats (6.89 per cent.), lactose, and total solids, was chalky- white in color, while that of another German (No. 8), which was yellow, was very low in fats, having only 2.31 per cent. Though the amount of lactose is more than a third greater than in cow's milk, yet the taste can hardly be called sweet, and while the total solids (13.27) and the specific gravity (1.0313) are both higher than in cow's milk, yet the consistency is much thinner. This is due to its much smaller content of albuminous matters, more especially of the caseinous or cheesy material. The average amount of nitrogenous matters (albuminoids) is somewhat greater at beginning of lactation, but the difference is not very marked. In truth, the feature brought out by this long series of analyses, which over- shadows every other in significance, is the fact that there is no progressive change in the composition of milk during lactation, but after the function has been normally established the milk remains substantially the same during the entire period. This is what might be anticipated from what much larger expe- rience teaches in regard to cow's milk, but it is at variance with notions com- monly entertained, and which have led to elaborate and utterly useless dieta- ries for infant nutrition. The child obtains more nutriment day by day, but it is by spontaneously increasing the quantity according to the best rule, which is that of normal appetite, and not by absorbing " stronger and stronger food."

On an average, human milk has about | of 1 per cent, more fat than average sound dairy milk, and 2^^ per cent, more lactose. On the other hand, it has \ of 1 per cent, less mineral matter, and, what is most important, hut 2 j)er cent, of albuminoids, or about half the quantity in cotv's milk. The fot is the most variable constituent, as is the case in cow's milk also. But in both the sum of all the other constituents besides fat is a nearly constant quantity, amounting in the vast majority of samples to about 9 per cent. The significance of this physiological fact must not be lost sight of. It shows that the final tendency and result of the complicated metabolic changes, which take place in the protoplasmic cells of the mammary gland, is to secrete a nearly constant total amount of nitrogenous, carbohydrate, and saline material, while allowing the secreted fat to exhibit a wide and independent variability. An increase in the amount of nitrogenous food does not increase the nitrogenous element in the milk secreted by a nursing woman beyond the general limit implied in the above rule, the metabolism in this case resulting in an increase of the fat. An excess of fiit, on the other hand, diminishes the metabolism. And, as a practical deduction from the above, there results the necessity of feeding a nursing woman on a diet which shall contain a sufficiency of pro- teid matters, but not on a rich food, the former yielding by transformation not only the albuminoids, but also the fats and lactose of the milk, whilst the latter may not in this sense be nourishing, and may impair the metabolic activity whereby the due proportion of the various constituents of the milk is normally maintained. It is necessary to the further understanding of the problem of infant nutri- tion, and especially of artificial feeding, to study in detail the similarities and differences of the individual constituents of woman's and cow's milk. Lactose. — The lactose in the two secretions is chemically, physically, and physiologically identical. The statements based on clinical I'esults to the efi"ect that the lactose of cow's milk exerted a peculiar diuretic action and produced glycosuria and set up abnormal digestive fermentations, etc. will have to be reviewed. Until very recently all the samples of lactose coming into my lab- oi'atory, even those supplied by manufacturers of highest repute as chemically pure, were far from being so. They contained residues of the proteids of milk and spores, the taste, appearance, and properties of the lactose being thereby altered. So great is the present use of lactose in medicinal preparations that correspondingly great improvements have been made in its manufacture, result- ing in the production of a very pure, hard, white, transparent, crystalline substance. The carbohydrate element, which is made up of starches, the many varieties of sugar, etc. in the food of adults, and which constitutes the largest part of most vegetables and fruits, is represented in milk by lactose only. This body is intermediate in its chemical properties between cane-sugar and starch, being, like the former, soluble, but with a taste hardly perceptibly sweet. Its main function is to supply by oxidation the animal heat, and, inasmuch as the human infant cannot maintain its animal heat by locomotion, and yet at the same time this heat must be preserved at even a higher temperatui-e than that of the adult, the lactose is relatively the largest constituent of human milk, forming more than one-half its total solid matter. Being already in a soluble condition, it is directly assimilable, and, unlike starch, requires little or no expenditure of energy to effect its transformation prior to digestion. Under the influence of certain bacteria, acting as ferments, the lactose is decomposed, with the forma- tion of lactic acid. Up to the present time ten varieties of bacteria, including, along with the bacillus acidi lactici, certain species of micrococci and sphaero- CHEMISTRY OF MILK AND ARTIFICIAL FOODS. 45 cocci, have been described as more especially concerned in the lactic fermen- tation of milk. They all bring about the curdling of the milk, but some of them at the same time give rise to the formation of gas and alcohol, and others do not. The primary change is due to the simple splitting of the molecule of lactose into four molecules of lactic acid by addition of a molecule of water : Lactose. Lactic acid. This change, which is the ordinary normal one, ensures the curdling and the development of lactic acid initiative to milk digestion. Under the influence of other ferments the molecule of lactic acid may break up into a molecule of alcohol and carbonic acid (CgHgOg = CgHgO + CO2), but this decomposi- tion is secondary and abnormal, and takes place less readily and more slowly than the decomposition of grape-sugar, glucose, or dextrose into alcohol and carbonic acid under like circumstances. Besides this fermentation, which results in the separation of a curd by means of lactic acid, there is another fermentation, which is accompanied by the development of a neutral or alkaline reaction. In this case the curd first formed may all eventually pass into solution, being converted into soluble pep- tones. The bacteria giving rise to these changes originate two soluble sub- stances acting as ferments, one acting like rennet to curdle the milk, the other dissolving the curd and exerting a peptonizing action. There is also produced leucin, tyrosin, ammonia, and, more especially, butyric acid, which last body gives its name to this kind of fermentation. Artificially, it is induced by con- tact with putrid cheese. In the digestive tract the butyric fermentation is usually brought about by the prolonged stay in the bowels of the undigested curds of milk or of a foreign irritant substance like starch, or by both. It is essentially a process of putrefactive decomposition, not present in normal digestion. In its simplest form the change may be represented by the formula 2C3Hg03 = C,H30, -f 2C0, H- 2H3O Lactic acid. Butyric acid. Carbonic acid. Water. While starch is the principal carbohydrate of adult food, it cannot properly be used in infant feeding on account of the absence of the ferment essential to its digestion. This starch-digesting ferment exists under the name of ptyalin in the saliva, and also is present to some extent in the pancreatic juice, but its amount in infants is very small, and its secretion is not established until after the third month. By its action the starch is made to take up a molecule of water and then decompose into maltose and dextrin, the latter body, by con- tinuance of the same action, passing into dextrose; thus: 3(CeH,oO,) + H,0 = C,,H,0,, + C,H,„0, starch. Maltose. Dextrin. 2(CgH,A) + 2H30 = 2(CgH,A) Dextrin. Dextrose. Liebig proposed to eifect this change by means of the diastase contained in malt, and his suggestion has been extensively followed. But the objection still remains that the saccharine substances thus produced, like the vegetable sugars in general, a,re not the same carbohydrate which is normally present in milk, and it has not as yet been satisfactorily established that they undergo in diges- tion the same series of changes and oppose equal resistances to abnormal fer- 46 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN, mentation. Though cane-sugar or sucrose, malt-sugar or maltose, and milk- sugar or lactose, all belong to the same general class of sugars known as sac- charoses, with the formula Ci2H220ij, yet their physical and chemical properties are essentially different, and so also their behavior when in presence of certain ferments. Pat.— So far as is known at present, the principal diff'erence between the fat-globules of woman's and cow's milk is in the relatively greater size of the former, which vary between 0.001 — 0.02 mm., while the latter average 0.00014 — 0.0063 mm. in diameter. The assumption that each globule is surrounded by a membranous envelope has been disproved, the finely-divided fat existing as naked globules, on the surface of each of which a number of albuminous molecules are condensed by molecular attraction, and the coalescence of the f;it particles thereby hindered. Albuminoids. — While the lactose of human and cow's milk is identical, and the fats are very similar, the nitrogenous portion presents so many and important diff'erences that the question of the successful substitution of coav's milk for human principally depends upon whether or no these diff'erences can be compensated or overcome. In both secretions the nitrogenous portion con- sists mainly of casein and lactalbumin. In addition, there are substances of the nature of peptones, in small quantities, but to what extent they exist naturally, and to what degree, in the case of cow's milk, they are formed by the peptonizing action of bacteria, is not at present determined. Casein is an acid body, existing in milk in combination with alkali, forming principally potassium caseinate. But the reactions of this body are complicated by the presence of other mineral bodies, and more especially of calcium phosphate. When dilute acid is added the casein of cow's milk readily precipitates in coarse coagula or clots, but that of woman's milk requires more acid for its precipita- tion and separates not in lumps, but in a fine powder which dissolves in excess of the acid. The lactalbumin remains in solution in the Avhey after separation of the casein. By boiling it is rendered insoluble. It closely resembles serumalbumin. While in cow's milk the total fraction of the albuminoids precipitable by acid (casein) exceeds by about four times the non-coagulable portion, in human milk these proportions are reversed, the non-coagulable part being about twice the coagulable portion. Similar diff'erences exist in the coagulum formed by theacid gastric juice : in the one case an excess of insol- uble cheesy masses, in the other a relatively small amount of finely divided soluble flakes, being formed. Taking equal weights of the two secretions, the coagulum of woman's milk is but one-fifth as much as that of cow's milk. The comparative smallness of this quantity must be as carefully considered as the diff'erence in the compactness and solubility of the coagula themselves. It explains the rapidity with which infant digestion is overtaxed even by small amounts of undiluted cow's milk. Inorganic Matter. — The mineral matter in cow's milk is more than three times that in woman's milk, and especially great is the excess of calcium phosphate, which is four times larger. This excess is due to the correspond- ingly larger amount of casein in cow's milk, with which substance the calcium phosphate and the potash are principally combined. The soda appears to exist in solution along with the lactalbumin as common salt. It is noteworthy that the lime is already relatively greater in the cow's than in human milk, and it is open to serious question whether the practice of using cow's milk alkalized by excess of lime is as desirable, in the case of normal digestion, as it was thought to be before the composition and properties of the constituents of milk were known. The following table presents the relative composition of CHEMISTRY OF MILK AND ARTIFICIAL FOODS. 47 the ash of cow's milk (Fleischmann) and of woman's milk (Konig), and also the percentages of each constituent (Bunge) : Cow's Milk.

The Chemistry of Artificial Foods. Two methods have been followed in the attempt to solve the problem of artificial feeding. The easier, and that most generally adopted, which would also appear to be the more natural method, is that of attempting to produce a food which should resemble as closely as possible woman's milk. The other method aims to produce a food or foods which should be especially adapted to the demands of nutrition for each particular infant in health or disease : it is open to great diversities of opinion, due to opposing clinical experiences, and is adapted rather to the treatment of special cases of dis- ordered digestive and other functions than to common use. By general con- sent the advocates of the first method have selected cow's milk as the basis upon which to build. The difiiculty of obtaining cheaply, readily, and of proper quality the milk of the ass, the goat, or of any other animal than the cow, has rendered the discussion of the possible advantages of such milk quite useless. Dilution. — The first expedient in connection therewith was that of dilution with water until the percentage of albuminoids and salts should approximate to that in woman's milk. But no amount of dilution with water alone is adequate to prevent the separation of the curd in coarse, indigestible lumps in presence of the acid secretions of the stomach. The next device was the addition of an excess of lime-water, so as to partly neutralize the gastric juice and allow much of the milk to pass unchanged from the stomach and undergo digestion in the bowels. As the chemistry of the milk salts indicates, the excess of lime is abnormal, and its addition is an expedient to meet a thera- peutic condition connected with an over-development of acidity, and not to change the nature of the difficultly digestible casein itself. Predigestion. — To effect this latter change previous digestion with dilute acid and pepsin was resorted to, and latterly this gave place to the more suc- cessful digestion with pancreatin in alkaline solution. Both methods were confined to cases of greatly impaired digestion, and the predigestion Avas carried as far as possible. But inasmuch as in woman's milk there naturally, remains about one-fifth of the albuminoids in a caseinous condition, the most recent practice is that of using a limited amount of pancreatin, acting for so short a period that the process shall initiate the peptonization, and then be arrested by the destruction of the ferment. The casein is thereby left in such a condition that it sepai-ates on acidifying as a fine white powder, while the biuret reaction for the albuminates becomes strongly developed. Sterilization. — Recently the fact that woman's milk contains no bacteria, while cow's milk usually contains large numbers and many kinds, patho- genic species possibly included, has been strongly insisted upon. To overcome this objection the practice of sterilizing the milk by repeated heating to a temperature above the boiling-point of water has been extensively followed. 48 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. So far as the destruction of all bacteria and their spores is concerned, the pro- cess is successful, but the clinical results which have attended the use of such sterilized milk have revealed serious drawbacks. It prevents the spread of zymotic diseases through the medium of milk ; it is efficacious in checking many gastro-intestinal disorders ; but its continued use is accompanied by its failure to aftbrd adequate nutrition. Besides the destruction of the bacteria, the prolonged heating to or above the boiling-point brings about other changes Avhich are in the nature of deteriorations. More especially the lactalbumin loses its solubility, and the fat-globules are made to coalesce with one another and some of the insoluble albuminous matter. For these reasons the appli-. cation of continued heat in the process of sterilization is inadvisable, and is now being discontinued. Sterilization at a Low Temperature (Pasteurization). — In this process of preparation the milk is kept for a brief interval, ten to twenty minutes, at a temperature of 160°-170° F., or raised during heating continued for ten minutes just to the boiling-point. While this process will not destroy all the germs which are in the form of spores, it will destroy the spores of tubercu- losis, scarlet fever, pneumonia, and typhoid, and almost completely inhibit the existence of the developed spores, or bacteria, of every kind. Pasteurization with Partial Predigestion (Humanized Milk). — The adjustment of the lactose and the bringing about of a permanently alkaline reaction are eflfected by the presence in the diluted sterilized milk of such an amount of lactose and of the alkaline milk salts as Avill effect this result. In order to raise the percentage of fat to that contained in Avoman's milk, cream may be added, or some vegetable oil like olive or cocoa, or animal oil like that of cod-liver. At present, by the aid of the Leval separator, cream has become a commercial article easily obtained, and its use is more convenient and better understood than that of the other fat substitutes, which require to be further investigated. Inasmuch as it contains some casein and bacteria, due allowance must be made for both in the process of modification heretofore explained. In practice, by the use of a preparation of pancreatin, lactose, and alkaline milk salts originated by Fairchild Brothers & Foster of New York, and known as "Peptogenic Milk-powder," the author has found that with ordinary bottled milk, cream, and water a modified sterilized milk is obtained which corresponds so closely to woman's milk that he has given it the name of "humanized" milk. The proportions recommended are — Milk \ pint. Water I pint. Cream 4 tablespoonfuls. Peptogenic Milk-powder 1 large measure. The mixture is heated on a hot range or gas-stove with constant stirring, the heating being so conducted that at the end of ten minutes it is brought to the boiling-point. The temperature of 160° to 170° is high enough to destroy the ferment, and this temperature, continued for twenty minutes, kills the bacteria also. But it is so much easier to quickly raise the temperature for a moment to the boiling-point, which also effects both objects, that the latter method is to be preferred when by a process of partial peptonization, as in the process described, the main portion of the albuminoids has been brought to a perma- nently soluble form. The milk thus prepared is slightly alkaline and sterile. It contains, accord- ing to the author's analyses, bottled market milk being used in its preparation, the following proportions of constituents : CHEMISTRY OF MILK AND ARTIFICIAL FOODS. 49 Fat 4.5 per cent. Albuminoids 2.0 " Lactose 7.0 " Ash _0^ " Total solids 13.8 per cent. When lime is used to counteract not only the slight acidity of market milk, but also with the object of forming a soluble calcium caseinate which will not be decomposed by the acid of the gastric juice and curds of casein thereby pre- cipitated, the lime must be added in considerable quantities. A mixture of 2 ounces of milk, 2 ounces of lime-water, and 2 ounces of cream, to which a teaspoonful of sugar of milk has been added, contains only a grain of lime, a quantity too small to effect any notable chemical change of the casein. If this mixture is sterilized, it should be done at a temperature between 160° and 170°, since heating to the boiling-point causes some decomposition of the albuminoids in presence of alkali. "Condensed Milk." — When condensed milk is used the preceding remarks require to be somewhat modified on account of the different modes of preparing this substance. This will be readily understood by comparing the composition of (I.) milk condensed with added cane-sugar, mean of forty-one analyses; (II.) the same diluted with eight times its weight of water; (III.) Anglo-Swiss milk, preserved without added sugar; (lY.) American-Swiss, preserved; (V.) No. III. diluted with five times water. I. Fat . . 12.10 Albuminoids 16.07 Lactose ....••.. 16.62 Sucrose 22.26 Ash 2.61 Total solids 69.66 Water 30.34 91.30 58.36 59.22 91.68 When largely diluted with water, so that the percentage of albuminoids is approximately the same as in human milk, the fat and lactose are brought far below the quantity proper for infant nutrition. Nor is the deficiency adequately supplied by the added sucrose of the milks condensed with this substance. Referring to these points, Dr. Louis Starr justly remarks : " Condensed milk is frequently recommended by physicians, and largely used by the laity on their own responsibility. It keeps better than cow's milk, and is supposed to be more readily digested by infants. The latter supposition is a mistaken one, and arises from the overlooked fact that condensed milk is always given dis- solved in a large proportion of water, while cow's milk is too frequently used insufficiently diluted or otherwise improperly prepared. The author is con- vinced of the accuracy of this statement from a number of years' close study of the subject. Condensed milk contains a large proportion of sugar, forms fat quickly, and thus makes large babies ; sugar also counteracts the tendency to constipation — often a troublesome complaint in hand-feeding. These advan- tages are unquestioned, and, together with the ease of preparation, are those which place it so high in the esteem of monthly nurses. It is equally true, how- ever, that as a food it does not contain enough nutrient material to supply the wants of a growing baby It must be remembered also that condensed milk, when long kept or when packed in imperfect cans, not infrequently undergoes decomposition, and thus becomes utterly unfit for use." Attenuation. — An entirely difi"erent method of increasing the digestibility 4 II. III. IV.

Experiments in the laboratory of the author showed that when diluted cow's milk, to Avhich a solution of cane-sugar, grape-sugar, barley-water, starch-water, or gelatin had been added, was treated with acid, the precipitated casein car- ried doAvn with it from one-third to more than tAvice its weight of the added substance. Gelatin more especially must be used in very small quantity, since otherwise it entirely arrests the precipitation of the casein. One of the simplest and best of these attenuants is barley-water, added to one-third its volume of milk. It may be prepared by boiling two teaspoonfuls of pearl barley in a pint of water in an open saucepan until the bulk is reduced to two-thirds, and then straining. Instead of barley, oatmeal may be used, or gelatin. To pre- pare the latter put a piece of plate gelatin an inch square into a half-tumbler- ful of cold water, and let it stand for three hours; then turn the whole into a teacup, place this in a saucepan half full of water, and boil until the gelatin is dissolved. When cold this forms a jelly: two teaspoonfuls are sufficient to thicken a mixture of three ounces of milk and five of water. Dextrinized Attenuants. — A gummv material like dextrin, or a gelat- inous substance, or a saccharine body, or a finely-divided starch like that occurring in barley- or oatmeal-water, along with more or less glutinous extrac- tive matter, is far better adapted to serve mechanically as an attenuant of the coagulated casein than farinaceous foods in their ordinary condition. Many difi'erent preparations are sold in which, by prior heating (dextrinizing) or by digestion with diastase, wheat and barley flours are modified to this end. By the action of heat at 300° to 400° the principal substance which is formed is dextrin, a body difi"ering from starch by its being soluble and by having the physical characters of a gum. Diastase produces principally maltose along with dextrin. The flour selected for either treatment should be highly albuminous, made of wheat grown at certain seasons and of certain grades, and should be the best grade of that made by the roller process. Grouping together under the head of soluble carbohydrates the sucrose, dextrose, maltose, and dextrin originally present or made by treatment, the changes can be traced in the fol- lowing table. The first column gives the composition of a wheat flour, the second the same after baking.

A sample thus prepared by Dr. J. Lewis Smith and analyzed at his request afforded the following results. It was boiled for five days, fifteen hours a day, or seventy-five hours in all, the bag being taken out of the water over night. The original flour was white ; the boiled flour, after thorough drying and pulverizing, of a light-yellow color. Its taste was remarkably flat and insipid, the long-continued boiling dissolving out the fat, some of the soluble albumi- noids, and mineral matters. It is possible that very different results might have been obtained from a flour of different character and boiled for a much shorter interval (Dr. Eustace Smith recommends but ten hours) : Original Flour.

The mixture is allowed to stand at ordinary temperatures for several hours, and then heated to 150° until the conversion of the starch into maltose and dextrin is completed. It is then strained and the residue pressed and exhausted with warm water. The extract is evaporated in vacuum-pans at as low a temperature as consistent with rapid- ity of working, and then dried with stirring at a higher temperature, so as to be brought into pulverulent porous lumps.

Still another class remains in which the dextrinized or malted flour has already been evaporated Avith milk, and which is prepared with the aid of water only.

The resulting biscuit is then finely ground and mixed with various amounts of condensed milk and dried by a slow heat at a moderate tempera- ture. This leaves a mixture in which the starch has been partly changed into dextrose, maltose, and dextrin : the albuminoids of the flour have undergone the partial decomposition spoken of in the case of the farinaceous foods; the casein has been dried into separate particles, and the lactalbumin has been coagulated. On the addition of water the saccharine and a small portion of the albuminoids dissolve ; the main portion of the albuminoids, the casein, and the starch, are left undissolved. In the actual preparation of farinaceous, Liebig's, and milk foods for use in the feeding-bottle, the adjustment of the relative proportions should be such as to afford a ratio between the fats, albuminoids, and saccharine materials as nearly the same as that in human milk as possible. By making the cow's milk the principal article of the mixture, and basing the approximation on such a ratio as will render the albuminoids not very different in their gross amount from that in woman's milk, foods of the following character may be obtained. Of course the constituents other than the albuminoids differ widely in their gross amounts, and what has been said before in relation to their relative values in nutrition must here be borne in mind also.

The wisdom of directing critical attention to the bodily exercises of chil- dren is coming to be better appreciated by physicians and teachers. It is not safe to assume the possession of inherent powers competent to spontaneously develop in all directions, and no argument is required to demonstrate the great importance of using all practicable means to bring about the fullest develop- ment of sound bodily and mental powers. Of yet greater importance is the need to husband and enlarge the vitality of those already handicapped by defective organization or depressing environment. The normal states of the infant are feeding and sleeping. Little more is needed during the first year of life than comfortable, clean surroundings, fresh air, and appropriate food, supplemented by ample rest. The little one should be left largely alone, distinct harm resulting from over-curious notice. Abso- lute freedom should be allowed the limbs by avoiding confining garments. In the second year it is a good plan to place the infant upon a soft cover- ing on the fioor and encourage all spontaneous movements. So soon as the child makes voluntary efforts at standing, reaching for objects, etc., supply harmless toys, especially such as can be kept chemically clean, as of rubber or metal. Let it exercise untrammelled the budding powers, that its muscular sense shall teach dimensions of external objects and its eye judgment of dis- tances and colors. The eye in the child soon becomes a perfected organ ; and so, indeed, the digestive tract, with limitations, of course, as to capacity. Not so, however, the limbs and trunk, which have much to learn and large need for exercise. Wearied out with joyful, spontaneous movements, which quicken circulation and expand the lungs, and feasted with slow contemplation of surrounding ob- jects, opportunity should be given to lie down comfortably and sleep. All childhood should be passed in a series of simple object-learning. Encouragement is very well, but no distinct teaching of any kind is needed until the motive powers are well established and a fair stock of intelligence has been acquired by unaided, slow mental assimilation ; avoid fine-spun theo- ries of childless philosophers and garrulous kinsfolk. The homunculus when fully able to cruise about the room or garden should do so, clambering up and tumbling down. So shall there come growing con- sciousness of capacities and limitations, so learn to save the imperilled head by use of hands, and gleefully secure and inspect coveted objects. Thus, little by little, stores of information are acquired, a knowledge which is all his own, because come at through abundant slow contemplation in his own time and man- ner and by his own unaided faculties. These aptitudes, too, grow by what they feed on. Selection is thus exercised : eye, hand, and leg are brought to the fulness of their strength, and the highest human faculty, judgment, is soon or 54 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. late acquired. In mere bodily activities a healthy child may be trusted to do enough and not too much. If urged beyond its own choosing, the element of excitement comes in, always a confusing factor in measures or results. Soon impressions from inanimate and other objects will no longer satisfy. Then comes the period of childish games, Avhen running, shouting, rolling about, give tone to muscle and prompt conduction from brain by nerve-paths to extrem- ities. When in the course of progress a certain time comes, by common con- sent, wherein systematic teaching should be had, then must the bodily powers and parts receive closest scrutiny. No school system is adequate which does not consider the training of the body as of almost equal consequence Avith that of the mind. Among the more comfortable classes this may be supplied by the fam- ily physician, but is all too rarely well accomplished. When this is not done, as among those who use the public schools, a skilled medical supervisor should be provided who shall pass judgment upon every scholar. Thus will be brought to light heretofore unrecognized weaknesses and deformities, or in the needful repetitions of these examinations hurtful tendencies may be early recognized and checked. In the matter of the eye supervision is becoming pretty generally exercised, and much good already accomplished thereby. Of yet more importance, however, is the quest of weak hearts, unsymmetrical backs and limbs, narrow chests, and twisted pelves. Soon or late, calisthenic exercises, military drill, class singing, or some systematic form of body train- ing will be a regular part of the day's instruction in most schools, with more of the open-air object-teaching by stream and field which is already used to supplement the didactic in many large schools and colleges. Among the most important defects needing attention are spinal deformi- ties. The commoner of these is lateral curvature, always a product of im- paired vitality with lowered respiratory capacity. This, before exhibiting itself in the posterior view, frequently produces alteration in the plane of the shoulders, the direction of the ribs, and shape of the chest. Scoliosis is a disease of development, its origin lying in weakness of the muscles which support the spine and in evil postures long maintained, strains in one locality producing compensating curves in some and rotation in other parts. Girls are much more subject to this deformity than boys, partly because they are muscularly weaker, but more, perhaps, by reason of a deplorable physical indolence Avhich custom encourages. Therefore enforced exercises, coupled always with periods of rest, are more needful for them than for boys. Many instances of spinal warping doubtless pass away unrecognized, owing to im- proved conditions occurring in the ordinary course of development ; but they will be revealed if critically searched for. This observation is proven by reports from examinations made by experts in schools, orphan asylums, and the like ; and if these sufferers be so circumstanced as to lack proper activities, or if hurtful influences supervene, or laborious occupation be assumed, these imper- fections become accentuated or even worse ones may appear. The remedy is to be found in varied muscular exercises taken at suitable times. The best are vigorous outdoor movements, games, leaping, running, climbing, and all sorts of hard play, the more varied the better. These, again, should, of course, be not unduly prolonged, especially for girls. Large scores at the skipping-rope and long match games at tennis, or even croquet, are prejudicial to female fibre. Indeed, the best forms of exercise for all children are those which speedily shift, being interspersed with ample periods of 7'est. Special forms of physical training for the young can only be touched upon briefly. Active games are very useful for alert, energetic children. Systematic drills or sports authoritatively directed have wider scope ; but the best results EXERCISE AND MASSAGE. 55 are had when skilled direction is afforded, both as to time occupied and amount of force used, directly to the individual. The German class gymnastics of free movements and Geratubungen, or exercises with apparatus, are valuable, provided not only definiteness is given to effort in kind and degree, but also the invaluable factor, incentive, is supplied. The most practicable and safe measures for regulating bodily defects are to be found in the Swedish system of educational gymnastics. Here each move- ment is grounded on a sound physiological reason, so that special movements can be formulated to suit special needs, and can be changed with advantage, less or more or other, on the "day's order." They are safe, reliable, and very efficacious. Direct injury to a child from over-exercise is rarely possible unless such excitement as ambition or fear over-impel ; moreover, when manifested, there is every reason to suspect organic defect, which may be thus savingly revealed. The burden of over-exercise in children is most liable to be borne by the organs of circulation, and such mischief as arises is attributable to disturbance in the balance of power between the ability of the heart to supply blood to the tissues and the eliminative capacity of the lungs and skin. The neuro-muscular mechanism is capable of enduring far more work than the circulatory activities will warrant. Profound fatigue, as from long exhaus- tive walks or runs, may reduce the child or youth to a helpless mass of inepti- tude, and then, if the spur of fear be applied, almost as much again of energetic output can be expected. The results from such an extremity of exhaustion will probably be a fever from the strain on the nervous discharges and the retained products of metabolism, which will burn itself out in a few days at most. If there be an organic weakness, that will probably be accentuated. The balance of nervous discharges may be so disturbed as to throw organic processes out of rhythm, temporarily or for longer time. Exercises of an exhaustive nature tend to produce the disturbances due to over-taxation of the organs of elimination. For example, heat-exhaustion is more liable to seize one who suffers from a lono; Avalk rather than a Ions ride. Emotion or excite- ment has most to do with producing over-work. The excited person, or one whose body has not learned to work economically under impulse, therefore makes a wasteful outlay of force, and exhaustion comes early, although it may not cause a cessation of work. The phenomena of over-work may be divided (as by Lagrange) thus : 1. Local fatigue or temporary tire, the discomfort which arises in a limb after an excessive number of muscular movements or contractions, the limit of which varies greatly acco];ding to the character as well as condition of the individual. 2. Breathlessness, which is loss of balance between the eliminative power of the lungs and the capacity of these organs to take in oxygen promptly and sufficiently — index of respiratory need. The stages of this are — Ji7'st, whole- some respiratory excitation, whence comes the bienfaisance which follows full respirations ; second, the labored, tugging efforts to void the CO^ and regain the balance of respiratory power : in this the vagi and heart-muscle play some part, but quite secondary to the auto-intoxication ; and third, carbon- dioxide poisoning to the brain, dulled intelligence, cyanosis, vertigo, cerebral vomiting, etc. Breathlessness is a sort of index of aptitude, indicating better than muscular fatigue the capacity of the individual. 3. Stiffness of the muscles, chiefly from insufficient dissimilation, or voidance of effete matters, also from traumata to the nerve-fibrils and tendinous insertions, etc. A boy, say of seven years, bears with great ease a large amount of running, interspersed with periods of rest ever so brief. This is largely due to the 56 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. admirable ease with which in the ehihl the lungs adapt themselves to the needs of forced respiration, whence he gets rid of the excess of carbon-dioxide. This same boy cannot with impunity endure long-sustained, unremitting effort, because " dissimilation is much more rapid in the child than in the adult," and the products of nitrogenous waste — of uric acid especially — are longer in forming and not so readily voided. The accumulation of these in the blood may produce a febrile attack in a child, as of gout in an adult. No absolute rule can be formulated by which the amount and degree of exertion suitable for each one can be recognized. This can only be determined by some knoAvledge of the individual's state or capacities. Much more harm comes of over-solicitude and limitations than from wholesome fatigue. Very excitable children can be over-tired readily, and some damage result, mostly of a temporary nature. The duty of the medical adviser is to estimate these powers and limitations and make them known to both parent and child. n. Massage. Massage, or the skilful kneading and rubbing of the soft tissues, is a remedial agent of recognized value. Originally, it was used as a luxurious accessory to the bath or toilet, but of a kind which produced substantial and desirable results, chiefly in the line of improved nutrition. As a therapeutic agent massage has been by many writers, mostly ill- informed folk, absurdly lauded, and hence for a time fell into merited disrepute, but latterly, its place coming to be better defined and its efi'ects more clearly known, it now enjoys a justly increasing popularity. Massage was early used mainly to remedy local defects, as exudations, infiltrations, and contractures. It was reserved for Dr. S. Weir Mitchell to direct the attention of the medical profession to the enormous value of general massage as a tonic and restorative. He makes use of it as the chief agent in " depriving rest of its evils ;" and in this original application is now followed extensively by thoughtful physicians the world over. The infant begins life as a passive agent, and excellent eifects are wrought upon its growth by judicious rubbing, with or without oil. The writer, early impressed with the possibilities of massage in the new-born, initiated a series of observations on babies during an out-patient obstetric service, and obtained unexpectedly gratifying results. These Avere supplemented by the experience of several other men in the new-born and in selected cases of malnutrition. The mother or nurse was instructed carefully in the simpler technique of massage, and directed to rub the child with olive oil ovef its entire surface daily, and to increase gradually the time and force used. No other cleansing medium Avas needed as a rule, and dangers from bath-chill were thus averted. Improvement was almost invariably gratifying, and at times brilliant, even when no ailment existed, but was especially noted in those below par. The beneficial effect was first observed in the skin, which softened notably, becom- ing clarified and rosy-tinted ; then fretfulness ceased and sleep came more amply, the bowel-action fell into normal sequences, and presently the muscles grew firm and strong. In beginning a treatment by massage the subject must be put in a com- fortable position in which all fatiguing muscular tension shall be eliminated* fully, and this will take wise, gentle handling and several sittings to accom- plish. The manipulator holds the part operated upon in a comfortable poise always, the subject not assisting at all; otherwise needless fatigue results. The movements should never be so sudden and jerky as to give pain, and EXERCISE AXD MASSAGE. 57 ere long the surfaces will become tolerant of T^"llat at first might cause discom- fort. It should be constantly borne in mind by the manipulator that the surface nerves and blood-vessels being thus highly stimulated, heat is evolved, which loss is liable to be followed by chilling of the part if left exposed. Therefore, as each part is disposed of. it should be instantly wrapped up in woollen fabrics. Technique. — As there are many perfectly satisfactoiy means of accom- plishing the same desired end, it is of primary importance to clearly know what that end shall be ; next, to bear in mind the tissues handled, their character, position, and function. While a pretty fair knowledge of anatomy and phys- iology should be possessed by the manipulator, a little less of knowledge and the over-confidence which this begets, and more of humble-mindedness, are a priceless boon to the patient. It is unnecessary here to elaborately describe the various manipulations, which are all reducible to four movements, and called by the Metzger school, curiously enough, by French names which signify stroking, rubbing, knead- ing, and tapping. These are distinguishable from one another partly through' their peculiar character, and partly by means of the different ends they aim to attain. Stroking (effleurage) is done from without toward the centres, exercising varying degrees of pressure, and its more prominent office is to expedite circulation in the blood and lymph-channels. Rubbing (friction) is chiefly done in little circles over limited areas with considerable pressure, and is designed to promote backward unloadings of vessels, as in exudations and infiltrations, and to press the tissue-refuse along the lymph-canals. Kneading (petrissage) is done by pressing or rolling together — a sort of pinching, which should, however, include so large a mass and so gently as not to hurt at all. Thus, also, the muscles are pulled to and fro from their beds, the more so when they especially need this action, as in contracted states from fimlty use or long disuse. The efi'ect aimed at is much the same as in friction, the keynote being to make the upper tissues rub the lower ones and to stretch out and elasticize stiiFened parts. Tapping, or striking (tapotmoit), is done by graduated blows of the finger- tips or side-hand, and is a potent means of mechanical excitation. This is most used on the larger muscle-masses, and helps to reach the structure below. Along nerve-trunks tapping or a modification of this, a tremulo movement called "■vibration," is claimed to be of value. The amount of time needed for a seance of massage varies greatlv. For local use five minutes to a quarter of an hour, for general tonic action, half to three-quarters of an hotu*. will usually suffice for childi'en. If too much time or force be used, exhaustion is liable to follow. It is imperative that a slow, progressive increase should be made the rule. A lubricant to the skin is rarely needed, and. if so. only at first, and should be some simple oil. as olive or cocoanut oil or a very nice quality of mineral oil. The last is liable to irritate ; the first to smell badly and foul the clothing. The direction of movement should be from the extremities toward the torso, beginnincr with toes or fingers and ending -with the trunk. After a few weeks it is generally wise to supplement this by regulated active "movements." The physiological efi'ect of massage is manifested chiefly upon the circula- tion, promoting this not only within the tissues operated upon, but directly influencing the circulatory activities of the peripheral parts lying adjacent, 58 A3fERICAN TEXT-BOOK OF DISEASES OF CHILDREN. and, as Von Mosengeil says, acting both as a pressure and suction-pump simultaneously. By virtue of this power, too, nutrition, local and general, is strongly influenced by the expedition of cellular exchanges, which, in turn, depends on blood-supply and lymph-currents. Thus, too, atrophic states are checked and repaired. A peculiar power resides in stroking to remove the painfulness of fatigue and to restore tone and comfort to muscles tired tempo- rarily or chronically wearied. This tire is both a vital and chemical effect, evidenced by faulty elimination of the products of metabolism, as carbon- dioxide, lactic acid, and the cadaveric alkaloids. As these are driven out by mechanical or other means, comfort and power return. According to Dr. Louis Starr, massage may be employed with advantage in the following diseases of childhood : (a) Chronic Gastro-intestinal Catarrh. — In this condition the skin is harsh, the muscle-tone is faulty, general nutrition is impaired, and there is a determination of blood from the surface toward the mucous membranes. To get the skin active, and in this way balance the circulation, is an important step in the re-establishment of normal digestion, secretion, and excretion, the essentials of perfect nutrition. To accomplish this a full, warm bath is admin- istered every evening just before bed-time, the patient remaining in the water for five minutes. Then the surface is thoroughly dried, and half an ounce of olive oil is gently rubbed into the skin, the child enveloped in a light blanket, and put to bed. After a little time diaphoresis begins. So soon as the sweating is free the skin is again dried, and the night-dress put on in prep- paration for sleep. Next morning, at some convenient time after breakfast, the child is subjected to twenty minutes' massage. The inunctions are con- tinued until the skin becomes soft and active, and massage is employed daily until there is a decided improvement in the amount of flesh and general strength, a period generally of two or three weeks. Afterward "movements" every third day will be sufiicient to complete the cure. (b) Constipation. — Manipulation is a very efficient remedy in habitual constipation, and there are many cases that can be cured by it, combined with a properly regulated diet, without the use of drugs. Petrissage of the colon is the best method, instructions being given to follow the natural course of the faeces through this portion of the gut ; thus, beginning in the right iliac region, to proceed upward to the right hypochondrium, to cross over to the left hypo- chondrium; and then downward to the left iliac region. Five or ten minutes every morning, or every morning and evening in obstinate cases, constitute the proper duration and frequency of the applications. The pressure must be gen- tle, as delicate tissues are being dealt with. (c) Colic. — Every experienced mother knows how often flatus, the cause of colicky pain, is expelled from the stomach or intestines by gently rubbing the abdomen with the hand. Any approach to scientific manipulation is much more efficient, and two or three minutes' effleurage may be resorted to, as the urgency of the symptoms requires, with the most satisfactory effect. In this connection it must bp remembered, also, that rubbing of the feet to increase the circulation is an important aid in relieving colic. {d) General Debility and Anemia are much benefited by short, fre- quently-repeated courses of massage. (e) Infantile Paralysis. — Here massage of the paralyzed muscles brings more blood into them, and maintains their nutrition until in favorable cases new cells in the cord take on the function of those which have been destroyed. In essential paralysis the affected members are always cold, and the muscles contract feebly, if at all, under the influence of electricity. By systematic EXERCISE ASB MASSAGE. 59 massage an improvement takes place with more or less rapidity. The first indication of this is an increase in the temperature of the parts, and then a return of the electrical contractility of the muscles. In recent cases the sittings should be of short duration and frequently repeated, five to ten minutes three or four times daily. As improvement advances the frequency may be reduced, and in chronic cases twice a day will be sufficient at any time; or once, if supplemented by ''movements." (/) Chorea. — So far as this branch of the management of chorea is con- cerned, it requires to be aided by proper diet and rest in bed. On the onset of an acute attack the patient is put to bed, given a full supply of good food, and allowed to rest for two days without massage. At the end of this time the regular treatment is initiated. The plan, a slight modification of that recom- mended by Goodhart, is as follows : The child — at seven years of age, for example — has at 5.30 a. m. half a pint of warm milk ; 7 A. M., half a pint of milk and three slices of bread and butter (each slice an ounce in weight) ; 9.45 A. M., a teaspoonful of Merck's dry malt in a little milk ; 10 a. m., massage for fifteen minutes, followed by half a pint of warm milk ; 12.30 p. M., a teacupful of rice pudding, half a pint of milk, green vegetables, and mashed potatoes ; 4.15 P. M.. half a pint of warm milk, three slices of bread and butter, and a lightly boiled egg ; 7 p. m., malt as before ; 7.30 p. M., massage for fifteen minutes, followed by half a pint of milk. At the end of ten days or a fortnight the bread and butter is increased to four slices at 7 a. m. and 4.15 p. M. ; a lean broiled chop is added to the mid- day meal, and an extra pint of milk is distributed over the twenty-four hours. After two or three weeks the patient may be allowed to sit up in bed. well sup- ported by pillows, and may have a few toys to play with. It is a golden rule, however, never to hurry a patient with chorea out of bed. The muscular strength is more quickly recovered while at perfect rest, and too early exer- tion often causes a relapse. {g) Other nervous diseases in which massage is employed with success are pseudo-hypertrophic paralysis, facial paralysis, neurasthenia and spinal irri- tability occurring in girls about the approach of puberty ; that ill-defined and painful condition so often encountered in young subjects and known as "growing pains;" and, finally, affections of the heart and kidneys. {K) Pleuritic efi"usions (serous), fibroid pleurisy, enlarged lymphatic glands, and stiffened rheumatic joints are all benefited by rubbing. In these special instances the manipulations are generally combined with the use of embroca- tions, though the curative effects cannot be attributed to the latter alone. SEA-AIR AND SEABATHING IN CONVALESCENCE. By W. M. POWELL, M. D., Atlantic City. The difference between the air of an inland town and that of the sea-coast is that the latter is not only pure, but is saturated with sea-salts from the break- ing of the waA-es upon the shore and the dashing of spray, which is carried toward the land by air-currents. If the wind is blowing from the sea, this characteristic saline odor may be noticed for some miles inland, but during a "land-breeze" it is hardly perceptible, even upon the beach. E. Freidick. in the Southern California Practitioner, quotes a large number of observers who have demonstrated the presence of sodium chloride in the air at the seaside, and shows that while there is naturally a small proportion of salt in this atmo- sphere, the greatest part of it is due to the diffusion of minute particles of sea- water. The proportion of salt is increased during strong winds, which blow the fine spray inland. The air of the sea has a peculiar odor which is difiicult to define, but which it is impossible to forget Avhen once it has been inhaled. This odor, which is caused by the evaporation of the extractive matter contained in sea-water, is stronger when the waves dash upon rocks covered with sea-weed than when they break gently upon a sandy shore. It is also more perceptible during a storm than when the sea is calm. Upon the border of the ocean the air is under greater pressure than in places of greater elevation, and consequently it contains more oxygen. The range of the barometer, the thermometer, and hygrometer is reduced to a minimum. These facts are only too often neglected in our estimates of the qualities of sea-air; they are, however, in a great measure responsible for the benefits derived by invalids during a residence at the sea-shore. Ozone is one of the constituents of the atmosphere which is found in abun- dance on the sea and adjoining coast. Schonbein, its discoverer, believed it to be naturally formed out of atmospheric oxygen by the electrical discharges constantly taking place in the air. It is a most powerful oxidizing agent, so destructive to organic miasmata that its mere presence is a warrant of the absence of such noxious elements. It is more abundant by the sea than inland, and in windy than in calm weather. It is well known that the climate of any place Avhere ozone is found in abundance must be healthy and exhila- rating ; hence we have at the sea-shore a pure air, containing oxygen in the form of ozone, besides finely divided sea-salts, as well as water which is ren- dered stimulating by the presence of the same salts. It most cases the breath- ing of this air has a marked invigorating effect, causing a great improve- ment in the appetite, promoting digestion and almost immediately producing a delightful exhilaration of the entire system. " No doubt can be entertained, in view of often-observed facts, that the effect of exposure to sunlight upon animal life is directly invigorating ; and when with this is combined the con- stant inhalation of salt-air, and the daily application of salt water to the whole SEA-AIB AND SEA-BATHING. 61 surface of the body and limbs, it is easy to see why children should gain health and strength at the sea-shore." — Packard. The temperature on or near the sea may certainly lay claim to greater uniformity than is obtained in localities remote from the coast. During the summer months the heated air of the land may be replaced by the cool breeze from the sea, while in winter the temperature of the coast-line is raised by the admixture of the warmer air from the sea with the colder air of the land. It is estimated that the Gulf Stream in this latitude during winter imparts to the air in contact with it a temperature of at least ten or fifteen degrees above that of the atmosphere of the earth, so that the ocean air in mixing with that of the land imparts to it an agreeable mildness which is unknown in the interior. Another favorable condition is found in the fact that the warmer air from the sea holds a large amount of invisible aqueous vapor in suspension, and as this commingles with the colder air of the land, it is condensed, gives out its latent heat, and becomes visible in the formation of clouds, especially at sundown. Thus that radiation of heat from the earth's surface into space which always takes place on clear nights is prevented. We can therefore safely assume that the mean temperatui'e of the sea-coast is neither so high in the summer nor so low in the winter as that which prevails in the interior. These facts are well illustrated in the following table, prepared by Sergeant W. D. Blythe from the reports of the United States Signal Office, giving for five well-known localities the mean temperature for each month and the year, computed from November, 1879, to December, 1884, together with the average temperature for each of the four seasons : Atlantic City, N.

On some days the diiference is greatly marked, and few of us have failed to experience the relief afforded by the first breath of sea-air after spending a day in the hot city. It is self-evident that the pleasantest climatic conditions are those which present the most even temperature, with only a moderate amount of wind and rain. The tables on the following page, compiled from the same source, give some interesting statistics of rainfall, temperature and wind at various well- known stations of the Signal Office. Touching the question of health, the national mortuary table offers important data. There we find that while such model cities of the interior as Roches- ter and Milwaukee, swept as they are by the cleansing winds of the great lakes, show a death-rate respectively of 23.39 and 24.52 per 1000; while Philadelphia, the healthiest, save London, of the world's great cities, shows 21.20 ; and while nearly thirty people to the thousand die annually in Charleston — the death-rate among the resident population of a sea-coast town like Atlantic City is 12.5. There are only two places in the United States — Ashtabula Ohio, and Los Angeles, California — where the death- rate shows any approximation to this last percentage. 62 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN.

Dr. A. W. Bell, author of Climatology and Mineral Waters of the United States, says that, considering the purity of the vapor and perfect solubility of the salt, it is difficult to conceive of any possible state of the human system under which the inhalation of such air would be detrimental. I fully agree with this author, and believe that sea-air is pref- erable to any other during a tedious convalescence. I know of no place where children improve more quickly than at the sea-shore. I have stud- ied this subject closely since 1883, when I was resident physician at the Children's Sea-shore House at Atlantic City, New Jersey. Since that time I have been connected with the same institution, where upward of seven hundred children, both convalescents from various acute (non-contagious) diseases and those affected with chronic ailments and strumous manifes- tations, are admitted yearly during the summer months. No one without experience can realize the benefit obtained by these little suffers, who remain at the Home for a fortnight to several weeks, according to the gravity of their cases. Here are sent, chiefly from Philadelphia, desperate cases of entero-colitis, patients almost completely prostrated by the heat, and other moribunds. Yet nearly all recover through the influence of the sea-air and SEA-AIB AND SEA-BATHING. 63 clean, healthful surroundings, with little or no aid from medicine. Dux'ing the summer of 1892, in the latter part of July and the first week in August, the heat in Philadelphia and vicinity was intense. At this time I had more cases of severe entero-colitis than for several years, but they all recovered rapidly, save one, a child sixteen months old, who died four hours after its arrival at the coast. At the Children's Seashore House, where my friend Dr. W. H. Bennett was in charge, the cases were more severe than usual, but all termi- nated favorably. It is an unusual circumstance for entero-colitis to develop at the sea-shore, and most of the cases seen there are brought from the neighboring cities or interior. Simple diarrhoea from indigestion, teething, etc. of course occurs. Convalescents from scarlatina, measles, and the eruptive fevers generally do well by the sea. The subacute nasal and pharyngeal catarrhs that we so often meet with in the spring as the results of repeated winter colds, which are usually so obstinate, invariably do well at the shore, where a complete cure is usually effected in a few days. Even cases of acute bronchitis seem to recover much much more rapidily, and chronic forms are much improved. My experience with phthisis in children at the sea-shore has been limited : I have only seen a few cases, and they were far advanced. These children seemed to do well for the first week ; the appetite improved, and sleep was more refreshing, although the cough remained about the same. After this they remained at a standstill, the improvement in appetite not being maintained, rest becoming disturbed again, etc. These cases improved for the first few days when taken home, but fell back rapidly. Asthmatic patients are frequently sent to the sea-shore, with, as a rule, most favorable results. Doubtless a long stay is beneficial to all such cases, especially those associated with chronic bronchitis. Patients arriving during a paroxysm nearly always experience an immediate relief, especially in cases of hay asthma ; but should the attack orginate at the sea-coast, removal to the city may in turn prove beneficial. Hyde Salter says : "I think it is a law, with- out an exception, that nervous affections are less prone to occur in proportion to the general bodily vigor, and what, for want of a more definite term, we must call the tone of the nervous system. Anything, therefore, that invigor- ates renders asthmatics less prone to their attacks. In this way sea-bathing is often of great service to asthmatics. By raising the standard of the general health it tends to prevent those humoral derangements which are often the exciting cause of asthma." Cases of a strumous origin invariably do well by the sea : the appetite improves, the color returns to their cheeks, and they gain in flesh. Russel, who was the first to appreciate all the benefits derivable from the salt air, always had the hair of strumous children cut close, and exposed them freely to the cool sea-air with the neck uncovered ; and he sent them back to their homes with their limbs strengthened and carrying in their countenances the evidence of the restorative powers of his remedy. When the strumous diath- esis has further advanced, the effect of sea-air, although still of great utility, is much slower. There are many cases of cure, even when the glands of the neck have been greatly swollen, under the influence of two or thi'ee seasons passed by the sea. Roccas tells us that such a deeply ingrained constitutional disease as scrofula cannot be eradicated without a prolonged stay in a marine atmosphere. When the glands are ulcerated, Whitt many years ago recommended fomentations with sea-Avater and poultices made with it. It is supposed to facil- itate the resolution of the swollen glands, even when they have become very 64 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. large and have existed for a long time. The follo"\ving case, reported by Rob- ert of Marseilles, fully confirms these assertions : "A lady coming from the interior of France brought to me her son, about fifteen years of age. The youth was enfeebled to the last degree, having been ill ever since he was nine years old. During all this time he had labored under scrofula of the neck, which was entirel}' surrounded with cicatrices of old ulcers. At the time I saw him the right elbow and one of the feet were aftected ; the elbow-joint was not diseased interiorly, but the ligaments which surrounded it were ; and there were fistulous openings which had persisted for a length of time. As regards the foot, it was pufiy and much enlarged, and he could scarcely bear it to be placed upon the ground : abscesses had formed several times, which had cicatrized, but there was another noAV threatening to open on one side of it. The most alarming feature of the case, however, was the terribly low state of the patient's constitution. His spirits Avere dejected; his face had the look of one prematurely old ; his skin was dry and flabby ; and his limbs almost entirely denuded of their flesh. Moreover, he was tormented with an almost continual diarrhoea. I advised the mother to establish her son upon the sea- coast, to make him pass the whole day upon the beach, and to make him use the sea-baths. Under this influence his general health began to improve, and then the swellings of the elbow and the thickening of the foot began to sub- side. Afterward I recommended that he should bathe daily, and that he should learn to swim. Hie fulfilled my orders so literally that he passed almost the whole of the latter part of the summer in the water. Always on the beach, he could find no other amusement so pleasant as that he derived from swim- ming. In a marvellously short time, considering the amount of disease, the youth was quite cured, and became what he still remains — a strong, healthy, and vigorous man." Rickets is another common disease of childhood in which the benefits of residence by the sea are marked. The influence of sea-air upon this malady seems to exert a marvellous amount of good, and West, in recommendation of it, says that " even where marked deformity has already taken place amendment Avill be sure to follow." I fully agree with this authority, but will state that my experience in the past tAvo years Avith this aff"ection has been limited, as the stay of my patients during the summer months is hardly sufiicient to shoAv improvement if the disease is far advanced. But I do believe a prolonged stay by the sea, say a year or more, will bring about a complete cure. Children suff"ering from Pott's disease, hip-joint disease, and arthritis of the knee all do Avell, gaining in flesh and improving in appetite Avithout medical treatment. Rheumatic cases, especially Avhen chronic, do Avell by the sea-coast, and I know of no better treatment for this disease than warm sea-bathing. Fortu- nately for this class of patients, most prominent sea-coast resorts noAv can offer all facilities for Avarm sea-baths. These establishments are fitted Avith every convenience, including a lounging-room or "sun parlor," Avhere one may take a nap after the bath. In cases of rheumatism the best results will be obtained from baths given on alternate days, followed by thorough friction of the body by a masseur or an intelligent nurse. Cases of chorea during convalescence improve rapidly at the sea-shore. Although many writers highly recommend sea-bathing in this disease, I do not agree Avith them. Indeed, in one case, almost A\'eli. I am sure a relapse was occasioned by fright caused by a wave striking the child. Warm sea-baths, folloAved by a gentle massage, are preferable. SEA- AIR AND SEA-BATHING. 65 Sea-air has a very grateful influence in inducing sleep. Often sick chil- dren brought to the sea-coast sleep the first night better than for many nights before. It will be found that many children who are not ill after a few days' stay will complain of drowsiness and willingly take their afternoon nap. The obstinate bronchitis which so often remains for an indefinite time after whooping cough is frequently cured by a few weeks' stay at the shore. In the paroxysmal stage of the disease, while the coughing spells are no less violent than elsewhere, children do not seem to lose flesh and color, no doubt because their appetite is kept up by the bracing effect of the clear atmosphere, and they are kept in the open air more than they Avould be in a city home. Cases of infantile paralysis make a slow but steady improvement during a long stay by the sea. Most diseases of the skin and the inflammatory dis- eases of the eye are not improved by sea-air, unless these troubles have a strumous origin, in which case a long stay, by improving the general health, will indirectly improve the local condition. Sea-bathing. — It is a popular belief that sea-bathing is both strength- ening and hardening ; and there is but little doubt that this opinion is well founded. It does not follow, however, that it should be practised by all with- out medical advice. Many hold that a plunge into water which is of lower temperature than air protects the system against attacks of catarrh and chill, and renders it indifferent to sudden climatic changes, whilst a few contend that perfect immunity from colds may be ensured by continuing the morning plunge throughout the year. We may say, without doubt, that sea-bathing, more than any other agent known, renders the body less sensitive to the influ- ence of cold and to the injurious eff"ects of prolonged exposure ; but this, of course, is due to its invigorating and strengthening properties alone, and not to the element of temperature. It is a remarkable fact that many persons who cannot profitably bathe in fresh water can do so in the sea ; and the explanation doubtless is that the abstraction of caloric from the body in salt water is less than in fresh, by rea- son of its greater density. Probably, also, the saline ingredients have a more stimulating effect upon the skin and induce a more energetic reaction. The most important characteristic of sea-water is its saline composition, and it is impossible to over-estimate the influence of the sea-salts in marine meteorology. It has been estimated that the average quantity of saline matter in sea-water is 3 per cent., consisting of chloride of sodium, sulphate of magnesium, sulphate of sodium, also muriate of magnesium and lime, with salts of iodine and bromine. Many, however, estimate the saline ingredients at 4 per cent. The above constituents are uniform as to presence, but are unequal in quantity in various parts of the world, so that in the Baltic a pint of water contains nearly forty grains of salt ; on the coast of Great Britain it contains more than half an ounce ; in the Mediterranean, much more ; and in some ports south of the equator the quantity amounts to more than two ounces. It is in consequence of its saline character that sea-water does not evaporate from the skin so readily as fresh water. Even when the body is carefully dried particles of saline matter remain adherent, and find their way into the pores of the skin — as may be proved by the application of the tongue to the surface — and keep up a tingling glow long after the bath is over. We all know that persons when soaked to the skin by salt water do not take cold as easily as when caught in a shower of rain. This is explained by the fact that the pungent action of the sea-salts so stimulates the cutaneous circulation as to enable it to resist the depressing effects of the cold produced by the evaporation of the fluid portion. Sea-bathing, besides having all the beneficial eff"ects of an ordi- 5 66 A3IEBICAN TEXT-BOOK OF DISEASES OF CHILDREN. iiJiry cold batli, lias others peculiar to itself. The contact of the salt ^vater and of the salt which adheres after the Avater left by the bath has evaporated stimulates the skin, increasin^^ the circulation and exciting the sudoriferous fflands. The beating of the ^vaves against the surface of the body affords a passive exercise, with some of the advantages of massage ; while to the more robust a healthful exhilaration and delightful active exercise are furnished by the plunge through the waves and the vigorous movements constantly required while in the surf. At the resorts in the neighborhood of New York and Philadelphia the sea- bathing season is usually considered to be between the first day of June and the last day of September, as in this interval the temperature of the water ranges higher than at any other season. The best time for taking a sea-bath is just befoi-e high tide. At that time the water has been someAvhat warmed by passing over the hot sand. More- over, the bathing is safer, from the fact that the tide still coming in Avould tend to wash the bather to the shore if he should lose his foothold, and, as the water covers a portion of the beach which was exposed to vieAV a few hours hefore, there is less risk from dangerous lioles and quicksands. But at most sea-shore resorts it has been found more convenient to bathe at the same hour each day — namely, at about 11 A. m., or two or three hours after breakfast, when the morning meal is digested and the system is beginning to feel the effects of the conversion of food into force, and is therefore better prepared to withstand the shock of the cold plunge. It is unwise, however, to bathe Avithin two hours after any meal : whilst digestion is proceeding more blood is attracted to the digestive organs, in order that the process may be efficiently performed. But if we divert a portion of the blood to the surface of the body by the action of the cold bath, digestion is suddenly interrupted, assimi- lation checked, and congestive headache, cramps in the stomach, etc. are caused. In order to answer several of the questions which naturally arise, it is neces- sary to describe the phenomena, which are as follows : On entering the water there is a shock, accompanied by a sensation of chilliness and shivering ; there is a respiratory embarrassment and a feeling of fulness in the head. Next follows a reaction, in which all these symptoms are relieved, and there is an agreeable sensation of warmth. If the bath is unduly prolonged, there follows another sensation of chilliness : the teeth chatter, the fingers and lips become blue, the respiration irregular and rapid, and the pulse Aveak and small. In the sea-bath each wave reproduces in a less degree the first shock, and at the same time hastens the development of the second chill. From the above description it would appear that the proper duration of the bath is a period short of the second chill, and the length of this period must depend upon the temperature of the water, the force of the waves, the strength of the })atient, and a number of other circumstances. I do not consider it wise to allow children to remain in the water over five minutes, and then they should be at once taken to their bath-house and not allowed to play on the beach in their wet bathing-suits. Before entering the water their heads should be wet, and they should be taken cautiously to the first line of breakers, Avliere, in a stooping posture, the waves may wash over them. If children are afraid of the Avater, they should not be forced. The proper Avay is to accustom them gradually to the sea. Have them dressed in their bathing-clothes and allow them to play on the beach, Avhen they Avill of their own accord go to the Avater's edge and gradually find their way in. Many children do not dread the water, and they may do much in allaying the fears of the more timid. I think three or four sea-baths a week quite sufficient 8EA-AIB AND SEA-BATHING. 67 for even the strongest child. A thorough rubbing down should always be given, and the child quickly dressed, and allowed to resume its play in a sunny spot unexposed to the wind. There is no advantage in taking an infant (under two years) into the sea, and the practice as usually carried out seems almost inhuman ; for these the heated salt-water bath is an excellent substitute. The Management of Children at the Sea-shore. — At all time of the year the sea-shore is most beneficial to sick children, but it has only been a comparatively few years since the practice of going to the sea-side resorts during the winter and spring months came in vogue ; previously, the three summer months were the only ones considered advisable to spend by the sea. At the present time it is deemed almost as necessary to take a child convalescing from an illness to the sea-shore in the Avinter and spring months as in summer. In selecting a place of residence by the sea it is well to be near the surf. Houses situated at a distance from the beach are never as cool as those close to it. Therefore, in taking a sick child to the shore it is always advisable, especially during the summer months, to select a house in close proximity to the sea. Here the exhilarating breeze comes uncontaminated from the ocean. The clothing of the child during its stay at the sea-shore should be slightly heavier than that worn in the city or country ; hence it is always better to use woollen under-garments, light and loose in texture. Long stockings should invariably be worn, even in the warmest weather, as toward evening the air becomes several degrees cooler, and, if the breeze is blowing from the sea, at times almost cold. Little change need be made in the food of children during their stay. The advantages, claimed by some authors, of a largely marine diet have probably been over-estimated, and much blame has been attached by others to fish, oysters, etc. for the frequent disorders of the digestive apparatus from which adults suffer at the sea-shore. From my own experience, however, the acute attacks of indigestion that we occasionally see are usually brought about by the elaborate menu which is found at our largest hotels, in contrast to the plainer home table which most are accustomed to. On arriving at the sea- shore the appetite is naturally sharpened by the change of air, and over-eating is the result. Much thought should be given to the necessity of exercise. Children seldom need much urging, but the want of it among adults probably interferes with many of the benefits which otherwise would be gained. For very young children, next to the walk in the nurse's arms, the drive upon the beach should be recommended. The perfect evenness of the surface renders it possible to take a very ill child into the open air frequently with the greatest benefit. One of the best forms of exercise for sick children is play- ing in the warm, dry sand. A spot should be selected where the sun does not beat too strongly, but which is at the same time perfectly dry. It is, as we all know, an unceasing source of amusement to children, and the harmless character of their little falls and tumbles during play often encourages them to efforts which they would not otherwise attempt. PART I. INJURIES INCIDENT TO BIRTH AND DISEASES OF THE NEW-BORN. By EDWARD P. DAVIS, A. M., M. D., Philadelphia. The mortality of the first year of life is variously estimated. Bernheim, from an extensive series of statistics, places it at ^"^yo^ per cent, of all chil- dren born. Winckel states that 10 per cent, of children born perish before the eleventh day of life; of these, -^^^ per cent, perish during labor itself, 3^ per cent, die as a consequence of some injury received during labor, while 2^Q- per cent, perish from diseases contracted at or after birth. We shall first consider morbidity and mortality among childi*en arising from injuries received at birth. Caput Succedaneum. The most frequent lesion sustained by the foetus during delivery is the formation of a tumor upon the head, usually known as caput succedaneum : this is commonly recognized after delivery as a somewhat boggy tumor, formed by infiltration of the scalp and fascia over the cranium, and usually situated upon the parietal bone opposite to that which came most in contact Avith the bony pelvis of the mother. The mechanism of its production is commonly thought to be as follows : In a normal presentation and position, the back of the child being to the left side of the mother's pelvis, and the vertex occupy- ing the left anterior half of the pelvis, during the stage of expulsion the left half of the vertex of the child's skull receives the greater portion of the impact of force during descent and rotation. The continued pressure upon this portion of the foetal skull temporarily checks the free circulation of blood and lymph through the tissues of the scalp and fascia. There remains upon the opposite half of the vertex a portion of the head less pressed upon by the bony pelvis; here, naturally, the blood and lymph of the scalp-tissues are pre- vented from circulating through the left side of the foetal head by pressure, and accumulate and distend the tissues of the right half of the vertex. The result is a tumor upon the side of the foetal head opposite that which actually engaged during the first stage of labor. The position which the child's head occupied in the mother's pelvis may then be reasonably inferred from the loca- tion of the caput succedaneum ; thus in the usual labor this tumor occurs in the right parietal region of the head. Should the child occupy a second posi- tion, its back to the right of the mother, its vertex situated in the right ante- INJURIES AND DISEASES OF THE NEW-BOBN 69 rior half of her pelvis, the caput succedaneum can be found upon the left parietal portion of the foetal head. Caput succedaneum is usually of no prac- tical importance, as it disappears in a few days after labor. The infiltrated con- dition of its tissues, however, forms an excellent field for the growth of infect- ing bacteria. Should the mother's birth-canal be in a septic condition during labor, or should, through the carelessness of the nurse in washing the child, some injury occur to the tumor, the entrance of septic infection results in inflammation, and, in rare cases, in abscess of the scalp. The caput succeda- neum is larger the longer the labor lasts, is usually of a bluish-red color, and does not distinctly fluctuate or pit upon pressure. Occasionally the tumor embraces both parietal bones : this may be caused by long delay in the expulsion of the child, the head remaining for some time in the external genitals of the mother. Upon post-mortem examination extrav- asations of blood varying in size may be found in the vicinity of the tumor, and do not indicate criminal violence after birth. Two of these tumors may be found, a primary and secondary : the first is formed in the usual manner : the second is produced while the head is upon the pelvic floor and after ante- rior rotation has occurred. If deliveiy then be delayed, a secondary tumor will form, and may be distinguished from the first by its situation in the median line. In shoulder presentations the tumor is found upon the shoulder which pre- sents. So far as the treatment is concerned, Bouchut suggests the application of a solution of ammonium chloride, a solution of camphor, or an alcoholic mixture containing camphor. If this does not secure the disappearance of the tumor, he would aspirate it. Winckel and other obstetric authorities incise the tumor if it persists beyond the sixth or eighth day. and make pressure upon the parts with salicylated cotton. If abscess forms, incision and irrigation with a -| per cent, solution of creolin are indicated. Oephalh.eiv[atoma. By cephalhEematoma Naegele, who fii*st described it, designated a blood- tumor on the foetal head, called true cephalhiTematoma when beneath the periosteum of the skull. and/a?.s-g cephalheematoma when beneath the aponeu- rosis of the scalp. Yirchow explains the formation of cephalh^ematoma by referring to the way in which the pericranium grows — namely, by proliferation of inner layers of the periosteum. If. then, the pericranium is separated from the cranium by the extravasation of blood, the bone-producing layers of the periosteum are still formed, but are prevented by the blood-clot from uniting with that portion of the bone for which they were intended. They join, however, to the bone at the border of the extravasated clot, where the bone is still attached. Fig. 1. Vertical Section through. CephalhEematoma. Much discussion has arisen as to the method of formation of cephalhse- matoma. Some ascribe its presence to traumatism only, while others seek an 70 A^IEBICAN TEXT-BOOK OF DISEASES OF CHILDREN. explanation in a pre-existing condition of the infant's tissues. It is to be differentiated from caput succedaneum by several important distinctions. The latter arises during birth, is born with the child, appears upon that portion of the head turned during labor toward the excavation of the pelvis, is more prominent after difficult labors, has an ill-defined border, frequently crosses sutures, is discolored in appearance, and doughy upon manipulation, and tends to disappear rapidly after delivery. On the contrary, cephalhsematoma does not occur, as a rule, after difficult labor, appears usually upon that parietal bone which did not present in the pelvic excavation, has a sharply-defined border, does not extend across sutures, does not discolor the scalp above the tumor, and usually gives the sensation of fluctuation in the centre of the mass. Cephalhoeraatoma also tends to increase steadily in size for some time after labor. With such radical differences the pathology of these tumors must differ widely. That of caput succedaneum has been already given. In studying the pathology of cephalhaematoma we have been struck by the fact that instances under our observation have been, as a rule, in ill-nourished children born without especially difficult labor. In the wards of the Philadelphia Hospital we. have frequently observed these cases in children born of ill- nourished mothers and poorly nourished at the time of birth. This leads us to believe that a pre-existing malnutrition lies at the basis of these tumors ; thus, cases are reported where, in addition to the cephalhsematoma, a profoundly anaemic condition of various organs of the child's body was present. In no case does this tumor occur as an extravasation of blood beneath the internal periosteum of the skull ; but extravasations of blood within the cranial cavity are also described under the title of " intracranial cephalhaematoma." Partridge describes two cases in Avhich coagulated blood was found beneath the dura mater. No injury to the bones of the cranium .existed in these cases, the brain-substance Avas softened, and the blood found beneath the membranes and at the base of the brain seemed to have been extravasated from the sinuses and from the laceration of minute blood-vessels. One of these children died very shortly after labor ; the other survived for several days. We recall a similar case where delivery was easily effected by the forceps ; the child perished, however, in thirty-six hours after birth, and upon post-mortem examination blood was found extravasated lieneath the membranes, while the underlying cerebral matter was softened. Here also no injury to the bones, membranes, or sinuses could be detected. Cephalhsematoma is more frequently found in males than females, according to Bui-chard, in the proportion of more than three to one. The tumor is usually found upon the right side of the head. The children of primipame are most liable to this complication in the proportion of three to one. As a rule, cephalhoematoma does not pulsate, although isolated cases are reported in which indistinct pulsation was observed. While fluctuation is usually present, it may be very obscure. This results from the presence of coagulated blood, as well as the breaking down of the clot in the centre of the tumor. It is observed that if the tumor be opened soon after formation, bright-red blood escapes ; later the blood resembles the fluid found after old extravasation. The deposition of bony material on the under surface of the periosteum occasions a crackling sensation when the tumor is palpated. The fluid escapes irregularly from beneath the tumor ; sensitiveness is very rarely a prominent feature. The bony ring surrounding the tumor forms gradually ; thus Bouchut observed a case before birth in which no ring was present. Semmel- weis is said to have seen cephalhaematoma in a child delivered by Coesarean section. INJURIES AND DISEASES OF THE NEW-BORN 71 Several tumors may develop in the same individual ; thus we recall a case under observation in the Philadelphia Hospital in which double cephalhge- matoma ajapeared on the head of a male child born after a normal labor. Triple cephalhsematoma has been observed by Oui after a precipitate birth in which Fig. 2. Double Cephalhsematoma. the infant fell to the ground, the cord rupturing three or four centimetres from the umbilicus. Upon examination a tumor was found upon each parietal bone, and one upon the occipital. The tumors were treated by incision and evacua- tion under careful antiseptic precautions, and uninterrupted recovery ensued. The occurrence of cephalhaematoma is readily understood when the loose attachment of the pericranium to the bone is remembered ; Valleix found that in almost all infants ecchymosis between the pericranium and the skull is present after labor. It requires, then, but a constitutional liability to ecchy- mosis by reason of malnutrition to readily account for the occurrence of such tumors. Cephalhsematoma, again, may develop after birth as a surgical injury, as instanced in cases described by Treves and N^laton, as also in a re- markable case in a bleeder reported by St. Germain. Cephalhsematoma may be also produced by injudicious pressure exercised during the child's toilette. Hiiter observed double cephalhsematoma occurring on the fifth day after birth, and caused by the carelessness of a midwife, who, in washing the child, rubbed its head with undue force. The tumors persisted as long as the individual had charge of the child, but disappeared soon after she was discharged. No one cause can be invariably assigned for the production of cephalhse- matoma: the size of the mother's pelvis seems to exercise but little effect, for Merttens in 21 cases found 6 in which the pelvis was normal, and only 5 in which slight pelvic contraction was present. In these cases the contraction was not of such nature as to interfere with labor. That the pressure of the pelvis has sometimes nothing to do with these cases is shown by Spiegelberg's observation of a case of premature birth at six months, in which the child perished before the rupture of the membranes ; he was able to examine the head in utero, and detected the tumors before the expulsion of the child. He considered the tumors caused by interference with the oxygenation of the 72 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. foetal blood, and oftentimes by premature efforts at respiration. Merttens reports a similar case in which he diagnosticated this complication before delivery. The foetus in this latter instance had a congenital hernia of the diaphragm, and hsematomata were found in other portions of the body. The diagnosis of cephalhnematoma in distinction from caput succedaneum has already been stated. Hernia cerebri may be present, but occurs usually in the occipital region and in the line of sutures. Pressure upon the hernia produces symptoms of positive disturbance of the nervous system. Aneurism presents a pulsating tumor of darker color, which neither has the appearance nor affords the history of cephalhfematoma. The effort to class this affection among the hydrocephali is scarcely successful in the light of our present knowledge of both. Blood-tumors found in the occipital region in the dead foetus are often caused by difficult labor, and are dark in color from the decomposition of effused blood. In encephalocele direct examination of the head by palpation will enable the physician to make the diagnosis. Tumors in living children, the result of direct violence, are usually painful on pressure and lack the sharp outline of cephalhsematoma. Occasionally, in advanced rachitis, where craniotabes is present, soft pieces of bone in the skull may simulate a blood-tumor when palpation is made through the scalp. The usual plan of treatment consists in making gentle pressure by a pad of antiseptic cotton conveniently held in place by a night-cap. Occasionally lotions containing dilute alcohol or some acetous preparation are employed, but there is no evidence of their positive value. It must be remembered that the tumor, as a rule, will have reached its largest size six or eight days after the birth of the child. Unless haemorrhage be excessive and the tumor becomes rapidly very large, it may be let alone for the first ten days of the child's life. Should infection occur and inflammation supervene, it must be freely opened at once, emptied of its contents, and the sac thoroughly disinfected, while continuous but gentle pressure is made by an antiseptic dressing. If no complication occurs, at the end of the first eight or ten days of the child's life the scalp over the tumor should be shaved, the surface thoroughly disinfected, preferably with boric acid, and the tumor punctured with a bistoury or large trocar. After evacuating the fluid contents pressure by an antiseptic dressing is indicated. Some prefer free incision in place of simple puncture. We have met with a case in which puncture and evacuation Avere followed by reaccumu- lation of fluid, and in which it was finally necessary to open the tumor freely, empty it, and pack it with iodoform gauze, the gauze having to be renewed several times before adhesion between the bleeding surfaces took place. Occasionally the loss of blood in these cases is considerable ; as a rule, how- ever, haemorrhage is not a serious complication. The susceptibility of infants to poisoning by antiseptics should be remem- bered in treating cephalhaeraatoma. Mercurial and carbolic solutions may be preferably replaced by solutions of thymol, 1 : 1000, or saturated solutions of boric acid. Iodoform gauze may be employed Avithout hesitation as tampon material. HEMATOMA OF THE StERNO-OlEIDO-MaSTOID MuSCLE. A peculiar induration is frequently observed in the sterno-mastoid muscle of new-born children, regarding which different beliefs have been held. Ana- tomical study of the subject shows that the lesion is an intramuscular fibrosis, caused by direct violence to the neck of the child, usually occurring at deliv- ery. Most of these cases result from delivery in breech presentation ; the INJURIES AND DISEASES OF THE NEW-BOBN. 73 forceps causes some ; and, rarely, the lesion follows spontaneous birth. Schmidt reports the case of a child, seven days old, delivered by the breech, in which the right sterno-mastoid was shortened, and the right half of the face smaller and flatter than the left. The report of a post-mortem examination upon a case pointing to a possible intra-uterine origin of this condition is made by Heusinger. The head was directed toward the left, the right sterno-mastoid muscle was 9 cm. long, the left only 6|^, and was a soft, white, tendinous sub- stance. In 23,293 children examined at birth at the Paris Maternity, Guyon found 132 cases of monstrosity, but no case of torticollis, which militates against the congenital occurrence of haematoma of the sterno-mastoid. In 64 post-mortem examinations Ruge found 13 cases of this complication. In a recent valuable paper Spencer describes 15 cases found in 300 autopsies ; his researches show that both sexes and the muscles of both sides of the neck are equally affected. Small, prematurely- born children are especially liable to this injury. Breech or footling presentation was observed in 10 of the 15. The forceps had been employed in 2 cases, while in 2 no instrumental aid was employed : in 2 of the bodies examined both muscles were affected. Spencer notes but two cases of contracted pelvis ; one of his cases was that of triplets, complicated by placenta praevia centralis, with extraction through perforation in the placenta. His microscopic sections show clearly rupture of muscular fibre, with extensive effusion of blood. It has been shown by Witzel that, as a consequence of this complication, contracting fibrous bands may form, giving rise to permanent wry neck. Jacobi believes that the forceps is frequently the effective agent in producing this injury to the foetus. HEMORRHAGE IN THE NeW-BORN. A considerable number of cases of foetal death occurring within the first forty-eight hours after labor are preceded by obscure symptoms which render an exact diagnosis difiicult or impossible. The intelligent study of such cases by post-mortem examinations shoAvs us that haemorrhage is usually the cause of the fatal issue. As in the adult, hgemorrhage may depend upon an alteration in the condition of the blood itself, and also upon direct mechanical injuries which result in its escape from the vessels. In the first category of cases it has long been a familiar observation that syphilitic children, stillborn, show extensive disintegration of blood, with extravasation of blood-serum from the serous surfaces of the body. Children dying from acute infections on the part of the mother, and stillborn or perishing soon after, often display such a tend- ency to haemorrhage ; thus, small-pox, typhus, typhoid, scarlatina, and, as a rule, the acute infections as a class, predispose to the occurrence of haemor- rhage. There is also direct proof from bacteriological examination that the foetus in utero may be infected by various micrococci, and that this infection may result in haemorrhage and death at labor or very soon afterward. The occurrence of multiple punctate hsemorrhages accompanying umbilical sepsis is a not infrequent illustration of this form of haemorrhage. In the recent litera- ture of the subject Tavel and Quervian report a case of multiple haemorrhage following umbilical infection by streptococci. Death occurred on the thirteenth day, the infection having occurred very shortly after birth. A thorough exami- nation of the specimens showed infection with streptococci and other bacteria to be the cause of the haemorrhages. These haemorrhages were found in the connective tissue beneath the epidermis, beneath the serous membranes and mucous membranes, and also in the kidneys. A second illustrative case is also reported, in which, in a prematurely-born child, death occurred with symptoms 74 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. of pneumonia. Examination revealed the fact that the pneumonia had been caused by infection with staphylococci. The peculiar form of the hasmorrhage — namely, into the parenchyma of various organs — excluded hemorrhage from mechanical injury. Further, the rapid and easy birth of a small foetus tended to exclude the possibilit}^ of mechanical injury. By far the most frequent cause, however, of haemorrhage in the new-born is direct mechanical injury received during birth. Such injury is usually suspected after difficult extraction by the forceps or by version. As pel- vimetry is more extensively practised the induction of premature labor will render these cases more and more infrequent ; but at present they occur with sufficient frequency to form an important complication of labor. Under the head of apoplexy neonatorum Ashby and Wright describe cases of haemor- rhage from the pia mater following compression of the umbilical cord and pressure upon the brain-substance during birth. Convulsions may be present in such cases, and if paralysis occurs it is probably peripheral, resulting from effusion of blood at the base of the brain, on the pons, or the origins of the cranial nerves. McNutt has reported 10 cases of cerebral haemorrhage follow- ing labor ; in 7 of these cases the head presented ; in 3, the breech. In all the latter cases paralysis occurred, but only localized convulsions. McNutt infers that haemorrhage, limited to the convexity of the cerebral hemispheres, is more apt to follow delivery in breech presentation. Various forms of cerebral haemorrhage are described by other observers, and especially in cases following prolonged application of the forceps or forcible extraction after version. In our own observation we recall the case of an infant delivered Avith axis-traction forceps without especial difficulty ; progress- ive feebleness of respiration, failure to nurse, and apparent exhaustion caused death in thirty-six hours after birth. On post-mortem examination, over the parietal regions of the skull the tissues of the scalp were intensely congested, although no gross lesion, as rupture or fracture, could be discerned. Beneath these portions of the skull and scalp the cortex of the cerebrum was filled with punctate haemorrhages, and over the point of greatest convexity the brain- substance was materially softened. Similar cases, which would not be found infrequent if post-mortem examinations in such patients were extensively held, are readily explained by the anatomy of the cranium and its contents in the new-born. Virchow and others have shown that the blood-vessels of the infant's brain are thin and small, and most readily injured by abnormal pres- sure. An interesting example of this fragility is found in cerebral haemor- rhage following death from asphyxia, Mhere mechanical injury to the cranium can be excluded. In medico-legal practice Richardiere emphasizes the fact that such cerebral haemorrhage may be differentiated from haemorrhage occurring later in life by the absence of inflammation of the arachnoid and of the dura mater. Menin- geal haemorrhage in the new-born is often accompanied by subpleural ecchy- moses ; death usually results suddenly. A most valuable recent contribution to the literature of this subject is that of Spencer. In a total of 180 bodies exam- ined, 130 were in a condition which enabled a critical examination of- the tissues to be made: in 85 injuries to the brain were found, consisting of con- gestion and hjemorrhage ; these conditions varied in severity, in situation, and in extent. Oedema was a frequent accompaniment. The children had been delivered in various ways, and many of the cases occurred in children the subjects of disease. The accompanying plate shows a typical condition of meningeal haemorrhage (Plate I.). Its frequency will be appreciated when it is known that 4^ per cent, of all haemorrhages occurring in the new- PLATE I. Visceral Hsemorrhage in the Newborn (Spencer, Transactions Obstetrical Society, London, vol. 33). INJURIES AND DISEASES OF THE NEW-BOBN. 75 born are meningeal in character. Spencer also describes a case, similar to the one which we have mentioned, of hemorrhage into the substance of the brain. It is interesting to note that, so far as the causation of cerebral haemorrhages is concerned, the forceps is the most frequent agent in producing them, and next presentation by the breech or foot. As .determining causes softness of the skull and relaxation of the sutures are of considerable importance. In Spencer's cases, next in frequency and importance to haemorrhage into the brain comes parenchymatous hemorrhage into the liver, kidneys, and supra- renal capsules. Well-marked congestion was frequently observed; haemor- rhage was present in 28 ^^ per cent.. This haemorrhage was often upon the upper surface of the liver and followed birth in head presentations. Such hgemorrhages usually appeared as blebs filled with blood. Of equal frequency was haemorrhage into the substance of the kidneys, usually beneath the cap- sule. Such cases were most frequent in breech presentations (Plate I.). The suprarenal capsules were also the seat of frequent hemorrhage. Injuries to the lungs in the form of congestion and haemorrhage were next in fre- quency. Most often this took the form of subpleural bleeding ; less frequently, as haemorrhage into the lung-substance. These pulmonary apoplexies are often followed by pneumonia, and are a frequent cause of death. Such infants are usually cold and blue, with sub- normal temperature and feeble cry, and do not nurse. The abdominal and pelvic viscera, besides those mentioned, are also the frequent site of congestion and hemorrhage. As regards the causes, Spencer recognizes a delicate condi- tion of the blood-vessels as of great importance. Alteration of the blood, already described, is also recognized, while asphyxia predisposes to hemorrhage. Direct mechanical violence is a familiar exciting agent. Experience abundantly proves that most cases of severe hemorrhage arise where disproportion in size between the foetus and the pelvis exists; there can be no rational prophylaxis of these injuries that does not rest upon an esti- mate of the mother's size and the relative size of the foetus. We cannot too strongly urge, as we have already done, that pelvimetry be uniformly practised by obstetricians, and that, in addition, an effort be made in all cases to estimate the relative size of the foetus and the birth-canal. To be of service to the patient such efforts at diagnosis should be made between the seventh and eighth months of pregnancy. So far as the treatment of the infectious disorders which attack the blood, resulting in hemorrhage, is concerned, the faithful practice of antiseptic pre- cautions will diminish very largely these complications. The need for such observances is proven by the familiar fact that at the present time the mortality of infants in private houses is greater than in well-conducted maternities, the reason being that the practitioner considers the private house and the private patient objects for less anxiety than the hospital patient; neglecting antiseptic precautions because the patient is a private one the result is often disastrous. Asphyxia. Interference with the oxygenation of the foetal blood results in asphyxia. By far the most common and dangerous causes of this complication are those which arise while the child is still in the uterus, and which have nothing to do with the access of the external atmosphere to the child's lungs. When this is kept in mind, it will be seen that asphyxia is a complication of labor itself, not so much a condition arising at delivery and requiring subse- 76 A3IEBICAN TEXT-BOOK OF DISEASES OF CHILDREN. quent treatment. The most frequent cause of this condition is pressure upon vessels of the placenta or umbilical cord, resulting in blood-stasis in the foetus ; or occasionally sudden collapse and death on the part of the mother. The symptoms of asphyxia in the foetus are those of carbon-dioxide poisoning — a rapid, feeble pulse, pallid appearance of the surface of the body, with the phe- nomena caused by intense congestion of various organs, ending in heart-failure. Asphyxia has been variously divided, some writers describing an apoplectic form and others a pallid form. These are but variations of the same condition, and are distinctions without essential differences. During the first stages of asphyxia the phenomena of congestion predominate : the face of the child is suffused, the mucous membranes bluish, the heart-beat at first slow and more vigorous than normal, while the reflexes still remain. As the process goes on and congestion has been followed by engorgement and oedema, the surface of the body is pale, the pulse small, rapid, and feeble, while the mucous mem- branes have the peculiar grayish-blue appearance characteristic of impending death. In the first stages of asphyxia the pulse in the umbilical cord is pres- ent, and may be vigorous. In the second stage the cord is pulseless, and shares the pallid appearance of the foetus. The complications of labor which most frequently cause asphyxia are par- tial detachment of the placenta, compression of the umbilical cord, pressure upon any large portion of the foetal body, especially upon the head and brain, or the sudden death of the mother. So soon as the tissues experience what has been styled " hunger for oxygen," there ensue reflex respiratory movements : by experiment these may be demonstrated to happen within the uterus before the rupture of the membranes ; they frequently occur during the second stage of complicated labor. They result in the inspiration of amniotic liquid or the secretions of the mother's birth-canal ; if these respiratory efforts are vigorous and prolonged, inspiration pneumonia may result — a catarrhal pneumonia caused by the inspiration of mucus or pus, developing, if the child survives, immediately after birth, and frequently proving fatal. The child before labor is in a condition of physiological apnoea. The blood of the foetus contains an excess of htemoglobin at the moment of birth, stated by Cattaneo to be relatively 120^ per cent. No differences can be distin- guished between arterial and venous blood in the umbilical cord in the amount of haemoglobin contained. So perfect is the provision of nature for supplying the foetus with oxygen that anajmia on the part of the mother does not seem to influence the amount of hemoglobin in the foetal blood nor in the blood of the child immediately after birth. The rapidity and ease Avith which the foetal blood absorbs oxygen is illustrated by the fact that in from thirty-six to forty- eight hours after birth the blood of the new-born contains its o-reatest amount of haemoglobin. Late ligation of the umbilical cord results in more haemoglobin in the foetal blood. Curiously enough, a small placenta increases the amount of hfemoglobin in the foetal blood, while a large placenta diminishes it. At the moment of birth the circulation of blood in the placenta and the child is markedly interrupted, oxygenation is materially lessened, and the foetus undergoes a period of more or less danger. It can be readily understood how delayed labor, where the exhausted uterus in tetanic contraction presses upon the child and the placenta, may occasion death from asphyxia, and this without extensive gross lesions. Asphyxia, again, may depend upon defective muscular and nervous develop- ment in the foetus. As a result, the foetus fails to make respiratory movements after deliveiy, and perishes from actual weakness. Diseases which affect the respiratory apparatus, either by structural changes or mechanical pressure, may INJURIES AXD DISEASES OF THE NEW-BOBN. 77 cause asphyxia. Pulmonary syphilis, enlargement of the liver, dropsy, and various tumors come under this head. These cases usually perish from atelec- tasis. The blood-vessels in such cases ruj^ture easily, and small multiple haemor- rhages abound. Prognosis in cases of asphyxia depends upon the condition of the ner- vous centres. If the asphyxia is but partial, and the stage of congestion be present, as evidenced by the dark reddish-purple complexion of the child and the slow but full pulsations of the heart and umbilical cord, recovery in the majority of cases will ensue. If, however, the child is pallid, the heart- beat rapid and feeble, and the cord pulseless, the prognosis is grave. More than 1 per cent, of children born living perish from asphyxia ; while cases have been reported where children, born asphyxiated, subsequently developed serious pathological conditions of the nervous system. Recalling what has been stated regardino; the richness of the foetal blood in hemoglobin, cases where children born asphyxiated have survived for hours, although thought to be dead, are readily explained. Beale described a case in which the mother died from post- partum haemorrhage shortly after delivery ; the mid^vife in charge reported the birth of dead twins, which she put in a basket in a shed ; on examination three hours afterward, one child was found breathing feebly. Efforts to establish respiration were fruitless. The temperature in the shed was very Ioav, the weather being cold. Children have respired feebly eighteen minutes after birth and twenty-five minutes after birth in breech presentation. Beale reports successful eflForts, lasting several hours, to resuscitate a child thought to be dead. A case is reported where a child was buried a foot under ground, and not exhumed for five hours, when evidences of life resulted from efforts at resusci- tation continued for two hours. It is curious to observe that the chances of recovery in asphyxia are much better when the infant is exposed to cold than when to heat, probably from the fact that a low temperature retards the metabol- ism of the cell-elements of the body, and thus the nervous centres retain their irritability longer. Treatment of asphxyia is prophylactic and curative. In prophylaxis the conditions which will result in prolonged labor should be anticipated and removed. Complicating factors which will subject the child to great pressure must also be obviated. The judicious use of the forceps is a direct prophylaxis against asphyxia, as are version and extraction. On the other hand, both of these procedures are direct causes of asphyxia in unsuitable cases. We must again repeat that no intelligent prophylaxis of asphyxia can be undertaken which does not include a preliminary examination of the mother's birth-canal and an estimation of the relative size of the foetus and the mother. Prolapse of the umbilical cord, resulting in pressure and asphyxia, is best treated by anaesthetizing the mother and terminating labor, if possible, by manual inter- ference ; thus, the cord may be taken in the hand and passed up into the uterus, the head brought into a proper position, and delivery expedited by the forceps; or, if pulsation in the cord has ceased, version and extraction may be performed. There is no repositor for the cord comparable to the hand of the obstetrician, for the hand can recognize pulsation, can remedy coiling of the cord about the foetus,. and may so change the position of the cord as to lead to the recovery of the foetus. In cases of contracted pelvis, or in disproportion between the foetus and the pelvis, operative procedures have for one of their purposes the saving of the child from asphyxia, which otherwise must prove fatal. So soon as the head is accessible during labor, the practitioner should ascertain, if possible, whether the cord is coiled about the neck ; if so, it should be gently drawn 78 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. down and loosened ; and if the head be born, the cord tightly coiled about the neck, and a large body and shoulders hinder delivery, it is well to cut the cord and deliver the child rapidly. The cord may be clamped with artery-forceps, or, better, tied. The diagnosis of cord around the child may sometimes be made before expulsion by hearing a murmur in the umbilical cord during auscultation of the abdomen. The treatment of the actual condition of asphyxia after delivery will depend largely upon the degree of asphyxia present. There are certain precau- tions which should be taken in every birth. The nurse sliould have ready a saturated solution of boracic acid to which has been added a teaspoonful of glycerin to the half pint. This should be at hand in a small, clean earthen bowl. In the bowl should be a half-dozen pieces of old, soft handkerchief, two inches square. When the head is born, the physician turns the mouth and eyes of the child in such a position that they will not come in contact with the discharges of the mother. The nurse or physician should then thoroughly cleanse the mouth and fauces with the bits of linen soaked in the boracic solu- tion. Mucus or secretions in the child's mouth will thus be removed, and one danger of asphyxia obviated. In the stage of asphyxia where congestion is the principal symptom, the stimulus of contact with the external air will often secure respiratory movements : spanking the child is a familiar method of procedui'e which undoubtedly has good results. In such cases the cord may be promptly tied and cut; and if the congestion be pronounced, it is well to allow a drachm or two of blood to flow from the foetal cord before ligation. The child should then be prompth^ inverted to favor the expulsion of mucus from the air-passages. If the heart-beat be good, a little cold water sprinkled upon the chest will usually result in the establishment of respiration. Should the heart-beat be good, but respiration not ensue, the child may be laid in a bath- tub filled Avith water at a temperature of 100 ° F., and passive respiratory movements may be instituted. Cold water also may be sprinkled upon the chest. In these cases a prognosis may be based upon the action of the heart ; if that be strong, the physician should not despair of securing respii-atory move- ments. In the more severe forms of asphyxia the child can endure no loss of blood ; it may be promptly inverted and held in that position for several moments, its mouth being thoroughly emptied of mucus and secretions : passive respiration is then to be instituted, and to secure the actual entrance of air into the lungs the Schultze method is undoubtedly pre-eminent. It consists in taking the child with both hands, the child's head raised between the upper portion of the palms, the fingers grasping the scapul?e of the child, the thumbs resting upon the anterior surface of the thorax. The child is then raised above the head of the physician until it turns a three-quarter somersault : it is then brought down with a swinging motion to within a short distance of the floor. When the body of the child is raised over the head of the physician expira- tion results : as the child swings forward and downward the action of gravity and the pressure of the physician's hands result in a powerful inspiratory action. The value of the Schultze method consists in its efficiency in intro- ducing air into the lungs ; it is not, however, a stimulus to the reflex excita- bility of the nervous system, and if this has been lost, an infant's lungs may be filled with air and yet the child readily perish. The dangers of this method have been pointed out by Meyer and Heydrich. Fracture of the clavicle with perforation of the lung and emphysema are reported by these observers as occa- sionally following this metliod of resuscitation. A manifest objection to the Schultze method is the disturbance and shock INJURIES AND DISEASES OF THE NEW-BORN 79 whicli must necessarily follow ; in deeply asphyxiated children, where the heart-beat is scarcely perceptible, it is preferable to practise the inverted posture, with the application of warm flannel to the surface of the body and the continuation of gentle respiratory movements. Air may be introduced into the lungs by mouth-to-mouth insufflation or by the passage of a tracheal tube. Lusk advises the use of the catheter, not only to remove mucus, but to favor direct insufflation ; or the chest-walls may be compressed to secure expiration. When circulation reappears, Silvester's method is then of service, the tongue of the child being drawn forward. When heart-beats are perceptible, the warm bath, with sprinklings of cold water upon the face, is useful. Finally, he advises Schultze's method to favor complete re-establishment of the circulation. Schultze claims for his method an immediate action in relieving overloaded blood-vessels, the swinging of the child producing empty- ing of the ventricles and favoring the return current from the pulmonary vein. The value of direct insufflation by the catheter, preceded by the removal of mucus, can scarcely be over-estimated. We recall a case in a foreign hospital where the assistant in charge had abandoned an asphyxiated infant as dead ; permission was given several American students to practise the passage of the balloon catheter, an English catheter having a rubber bulb at the distal end, whose compression and expansion favor suction and insufflation. To our surprise, the child became resuscitated under the use of the catheter, and ultimately recovered. Forest places the child first on its face, its head down, and expels fluids from the mouth by pressure upon the back. The child is then put in a bath or tub of hot water in a sitting posture, supported by one of the operator's hands across its back, its head bent back- ward. The physician grasps the child's hands with his other hand, carries them upward until the child is suspended by the arms, leans forward himself and blows air into the child's mouth ; the infant's arms are then lowered, its body is doubled forward, and its thorax pressed between the hands of the physician. Air is thus expelled. Especial advantage is claimed for this method from the fact that the hot water maintains capillary circulation and tends to assist in promoting the action of the heart. Reynolds places the infant upon its back, head downward, resting upon the operator's forearm, held nearly perpendicularly to the floor, retained in that po.sition by his fingers hooked over its shoulders. In this position the child's arms fall down- ward by the sides of its head, and their weight, aided by that of the thorax itself, draws the ribs into the position of complete expansion of the chest. The thorax is compressed against the forearm by the other hand, and suddenly released, when a most satisfactory respiration is the result. This method combines a favorable posture for the escape of fluids from the trachea and for the afflux of blood to the brain, with a ready method of artificial respiration. Duke places the infant face downward, its thorax resting upon the open palm of the left hand ; the ribs are gently compressed by the other hand : the mouth is cleansed, and the finger passed down the pharynx to admit air. If this is not successful, the child is plunged into a hot bath. Richardson urges that the child's body remain quiet during efforts to establish respiration. The feeble condition of the heart strongly contraindicates violent disturbance to the child. The position of the body should be horizontal. Air introduced should be warmed to 90° F. Manual respiration by Silvester's or Hall's method is recommended, and Richardson describes an apparatus composed of a pair of bulbs by which air may be pumped into the respiratory passages. Two pieces of tubing are passed to the nostril, and a bulb upon one injects air, while a bulb upon the other favors the discharge of mucus and vitiated air. 80 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. He also describes a method of using a simple bellows in connection with a nasal tube. The treatment of asphyxia by tracheotomy is seldom successful ; there is rarely an impediment in the respiratory passages of the child which cannot be overcome by the introduction of the catheter. In reviewing the treatment of asphyxia we desire to call attention to the pathology of the affection and to the relative value of different methods of treatment. The removal of mucus from the nostril, trachea, and bronchial tubes can be most readily effected by suspending the child in an inverted position ; this favors also afflux of blood to the medulla and respiratory centre. Gentle, passive respiratory movements should be employed, but so conducted as to give the child the least disturbance possible. The return of the circula- tion and the reflexes should be eagerly awaited, and so soon as these phenomena are present the prognosis becomes much more favorable. The warm bath and the application of a mild counter-irritant — cold water, spirits, simply a current of air from bellows directed against the epigastrium — usually cause respiratory movements. In strong children, when the reflexes are present and the heart-beat becomes perceptible, Schultze's method, practised gently for a short time, is of value. Should the circulation fail, it is admissible to inject hypodermatically y^ of a grain of strychnia and a few minims of tincture of digitalis. If mucus is not expelled by the inverted position, the use of the catheter with suction and insufflation is advisable. When respiratory efforts have become established, but repeatedly fail, a mild faradic current of electricity and the inhalation of oxygen under pressure are of decided value. One pole of the fjxradic battery should be placed at the back of the neck, and the other over the thorax and alternately over the epigastrium. Bonnaire obtained good results in foetal asphyxia by inhalation of oxygen — a procedure which we have repeated with like good results in foetal asphyxia and that of older children complicating pneumonia. As Lusk remarks, in cases of deep asphyxia patience, watchfulness, and a hopeful spirit are prerequisites of success. Following asphyxia, the infant is exposed to danger of death from inani- tion, and, as has been stated, from catarrhal pneumonia. The use of the incubator is of especial value in maintaining the circulation in these cases, and favoring the gradual expansion of the lungs if atelectasis be present. Winckel has obtained good results from the permanent hot bath at a tempera- ture of 98.6° to 100° F. every twelve to twenty-four hours. Such children are fed every two hours. The bowels are promptly emp- Fig. 3. tied by rectal injections. Winckel has devised a bath- tub for such cases, an illus- tration of wliich is append- ed. We add also an illus- tration of a modification of Auvard's incubator, which we have used successfully in the Philadelphia Hos- pital and in the Maternity Department of the Jeffer- son Hospital. The interior of the box is divided into two parts by an incomplete horizon- tal partition, placed about six inches above the bottom of the box. In the lower part, which is intended for hot cans, two openings are necessary — one at The Permanent Bath. (Winckel).

HEMORRHAGES FROM MuCOUS SURFACES. The new-born infant often presents hjxjmorrhages from mucous surfaces of the body. Among the most frequent of these is a discharge of blood from the vagina, occurring at birth and persisting afterward. An examination of the mucous membrane in these cases frequently detects a condition of capillary granulation which bleeds easily upon the slightest movement of the child. In a case recently under our observation at the Maternity Department of the Jeiferson College Hospital an ill-developed female child presented this phe- nomenon at birth. A blood-count made of this child, and compared with that of a healthy infant, shows the following : Healthy Child. — Red corpuscles per cubic millimetre, 5,450,000, by counting forty squares (Thoma-Zeiss ha?mocytometer). White corpuscles per cubic millimetre, 11,000. Proportion of white to red, 1 : 495. Haemoglobin, 65 per cent, of normal. Blood-plates by objective, blood prepared by means of Hayem's solution: the number was much less than the usual amount, which should be about 250,000. The red corpuscles were irregularly formed, some crenated, some small and granular, others apparently rolled or turned upon themselves, resembling very much a bread roll. While this irregularity existed, their appearance was that of normal corpuscles, and the percentage of haemoglobin (65) proved them to be almost normal. In children the per- centage of Inemoglobin is not so great as in adults ; in the young or in any case where the growth is rapid the red corpuscles are always irregular in appearance, which is not at all indicative of disease. The slight increase in red corpuscles is normal to the new-born. (Plate II. Fig. 1.) Ancemic Child. — Red corpuscles per cubic millimetre, 2,000,000. White corpuscles per cubic millimetre, 12,000. Proportion of white to red, 1 : 166. Haemoglobin, 35 per cent, of normal. By careful examination no blood- plates could be found. In this case the red corpuscles were irregular, crenated, granular, and many disintegrated. By actual count this specimen would give over five million red corpuscles per cubic millimetre, but counting normal corpuscles Avould give only two million. The object of the count being to know the number of oxygen-carriers per cubic millimetre, it would give a wrong idea to enumerate those disintegrated and diseased corpuscles. There was a slight increase in the number of white cells, but their appearance was normal.^ (Plate II. Fig. 2.) The condition underlying such haemorrhage is that of anaemia or malnutri- tion of the blood, with resulting ecchymoses. In parts accessible to treatment, as the mouth, vagina, rectum, or bladder, injections of hot dilute creolin solu- tion or boracic solution are indicated. Treatment of the anaemia, however, by administration of food, by arsenic, inunctions with oil, and the administra- tion of olive or cod-liver oil will result in gradual recovery. Obstetric Paralysis and Injuries to the Nervous System. Direct injury to the nervous system received during birth has long been recognized as among the dangers to which the infant is exposed. Paralysis of ^ P^or the examination and description of the blood in these cases I am indebted to Dr. T>. B. Kyle, Instructor in the Examination of the Blood in the .Jefferson Medical College. Dr. W.

INJUBIE>S AND DISEASES OF THE NEW-BORN. 83 the facial nerve caused by pressure with the forceps upon the nerve at its fora- men of exit often follows instrumental delivery. The brachial plexus is also frequently injured by the same agent. Hemiplegia, idiocy, and impaired cere- bral development have been ascribed as consequences of injury received at birth. The view previously held, that the forceps is a valuable agent for compressing the foetal head and exercising leverage and forcible rotation, has given place to the belief that the forceps is essentially a tractor, and that the mechanism of rotation depends upon the relation in size and symmetry between the head and the pelvis, and, as well, the resistance of the pelvic floor. Murray has shown by experiment and clinical observation that the foetal skull is com- pressible in an antero-posterior direction by the sliding of the occipital and frontal bones under the ends of the parietal bones. This compression is not accompanied by any appreciable increase of the transverse diameter. The antero-posterior shortening is compensated for by a vertical elongation of the skull, providing for the accommodation of the cranial contents. These con- clusions are, however, based upon the employment of axis-traction, without which such compensatory elongation cannot be confidently assumed. Murray was also careful to avoid forcible traction. Under such circumstances it may be held that moderate pressure with forceps, resulting in compensatory elonga- tion of the vertical diameter of the foetal skull, need not be expected to cause paralysis, haemorrhage, or fracture. This pressure, however, must be gradually applied, and traction made in the axis of the pelvis ; otherwise a portion of the head will be forced against the promontory of the sacrum, and injury must result. When gentle axis-traction fails to cause the head to descend, a diag- nosis of disproportion between the head and the pelvis should be made, and efforts at forcible delivery should cease. The results of injudicious delivery with forceps are well illustrated by Lane. A boy sixteen years old, delivered at birth with forceps, exhibited a groove three and a quarter inches long from the right coronal suture to the lambdoid ; the floor of this groove seemed one-fourth of an inch below the scalp ; the left arm was weaker than the right, and its movements defective. The left leg was weak. Reflexes were exaggerated and clonus was present. The depressed portion of bone Avas raised ; the bottom of the depression encroached upon the area of the skull. Prompt amelioration of the epilepsy followed. Duchenne, Gueniot, De Paul, Rogers, and others have described injuries to the brachial plexus caused by forceps and by manual extraction of the child. Erb has clearly described injuries to the brachial plexus accompanying delivery in breech presentation. Hoedamaker describes injury to the fifth and sixth cervical nerves resulting from delivery in breech presentation when the arms become extended above the head. Feriberg describes a case of paralysis caused by pressure upon the brachial plexus during delivery after version ; paralysis was but temporary, the patient subsequently making a good recovery. The medico-legal aspect of injuries to the new-born child requires the dif- ferentiation of lesions received during birth by forceps or the pressure of the mother's pelvis, and injuries occurring by precipitate labor without assistance or by the wilful act of the mother or an accomplice. Dittrich reports cases of depression in foetal bone, bounded by a well-defined ridge, following applica- tion of the forceps in cases of contracted pelvis. Klistner describes funnel- shaped depressions in the foetal skull following forcible delivery by forceps. Von Hofmann has found a spoon-shaped depression the most frequent form of lesion in a considerable number of cases. Fracture of the orbital region of the skull has been observed by Lihotzky to follow forcible forceps delivery. Rup- ture of a meningeal vein and death from haemorrhage have been observed. and 84 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. reported by Koffer in the clinic of Gustav Braun. Kundrat reports an inter- esting case of depression upon the parietal bone of a new-born infant, with cerebral haemorrhage, in Avhich the evidence seemed to show that the lesion was caused by direct violence on the part of the mother after the birth of the child. Von Hofinann has further drawn attention to injuries to the foetal cadaver which might occasion suspicion of intentional violence during birth. Naturally, defects in the ossification of the skull may result in lesions accom- panying normal labor and simulating injuries at birth. Fritsch describes the characteristics of injuries caused by precipitate labor, the child falling upon the floor or ground, to be as follows : The fracture begins in a suture, and extends outward to the middle of the bone ; usually there is but one fissure, which ends where the bone is thickest. The parietal bone is most often affected, the fissure ending in the parietal eminence. As a general distinction, it is to be observed that direct violence is accompanied by haemor- rhage ; that injuries examined immediately afterbirth, where fracture occurs, show frequently a Avell-defined border to the lesion, which tends to grow less sharp in contour if the child survives. Kundrat also lays stress upon the rela- tive breadth of the sutures as a factor in influencing lu^emorrhage during birth. A most interesting question arises as to the bearing of these injuries upon the future health and development of the child. Osier found, in the records of the Philadelphia Infirmary for Nervous Diseases, 9 cases of paralysis following forceps delivery ; in G of these it was reported that the forceps injured the child : some of them had scars following labor. In all cases the paralysis grad- ually appeared Avithin a short time after labor. M. Allen Starr describes cases of brain-atro{)hy manifesting itself in hemiplegia, mental defects, and sensory defects, accompanied frequently by epileptiform seizures, and result- ing from congenital conditions or lesions occurring at birth. Sachs and Peter- son in 49 cases of congenital cerebral palsy found 16 in which some difficulty in labor occurred. These statistics are now more comprehensive than those of Little and Gaudard, Wallenberg and Osier. Sachs and Peterson, however, include all forms of cerebral paralysis and of tedious labor as well as instrumental delivery. Sachs has expressed the opinion that prolonged labor does more injury to the child's brain than the proper application of forceps. We have considered the prophylactic treatment of these conditions under that of the treatment of visceral Imemorrhage. The question arises, however, What shall be done in a case in which a child is born and survives Avith such an injury ? Although we find no record that such a procedure has been at- tempted, yet the suggestion of Nancrede and other surgeons that depressed bone be elevated by surgical interference is certainly rational. We believe that where pressure-symptoms are present, or where the lesion is extensive and follows severe pressure, such .should be the line of treatment. The success attained in operating immediately after birth upon cases of umbilical hernia gives encour- agement to the belief that surgical interference in these cases is justifiable. It is interesting to note a superstition common among the laity in some quarters to the effect that the doctor by manual pressure and counter-pressure is ex- pected to shape the head of the child during the first few days after its birth. Fractures and Dislocations of the Trunk and Extremities. The skeleton of the foetus may be fractured while in the uterus. Such fractures, however, must be carefully distinguished from congenital malforma- tion, which closely simulate fracture. Amniotic adhesions during the first and second months of intra-uterine life are the most frequent causes of these mal- INJURIES AND DISEASES OF THE NEW-BOBN 85 formations. An apparent scar is often present in these cases, and must be referred to precipitate flexion of undiiferentiated layers in the embryo. Spurious callus may be present, caused by defective development of the bone, although the amount of callus is less than after actual fracture. Sperling would dis- tinguish between malformation and fracture by the fact that in malformation the fingers and toes of the limb affected show defective development, while in fracture such defective development of fingers and toes is absent. Hodgen de- scribes a foetal skeleton containing sixty-five fractures which he thinks were caused by muscular action during uterine life. He describes also, in a healthy child, a fracture of the clavicle, which was not discovered for several days after birth ; the child was large and was delivered by forceps. The most frequent fractures in the long bones are those of the clavicle, humerus, and femur. Fracture of the clavicle near its acromial end is occa- sionally complicated by severe injury to the brachial plexus, as illustrated in a case reported by Knight ; permanent injury of the shoulder with paresis fol- lowed. Fracture of the clavicle is most frequently caused by forcible extrac- tion of the shoulders. Fracture of the humerus most frequently occurs in the delivery of the after- coming head when the arms become extended above the head. Fracture of the femur usually results from difficult version and extraction. Fractures of the bones of the leg, of the ribs and sternum are rarely met with, and only in cases of forcible extraction through highly-contracted pelves. Dislocations of the foetal skeleton are frequently confused with fracture, and are caused by the same manipulations which give rise to solutions of conti- nuity. Dislocation and separation of the epiphyses of the humerus at the elbow- joint have been not infrequently observed after manipulation. The treatment of fractures and dislocations of the trunk and extremities is based upon the principles of surgery commonly followed. Difficulty has been experienced in maintaining the fragments in apposition by reason of restless- ness in the child, and the. necessity to move it frequently when it nurses and when it is cleansed. Fractured clavicle will heal without deformity with a very simple retention dressing if the infant be kept assiduously upon its back. Fracture of the humerus and of the femur may be treated to advantage by some form of splint material which can be dipped in hot water, moulded to the child's limb, and retained in position by a simple roller bandage. Firm and unyield- ing dressings must be avoided in these cases, as the danger of injury to the tissues by pressure is very great. Fractured ribs and sternum may be success- fully treated by a broad flannel bandage pinned smoothly about the chest. Dislocations require the same principles of treatment which should be followed in managing fractures. The prognosis in fractures of the foetus is usually good. As most of them are of the " green-stick " variety, a favorable result without deformity is the rule rather than the exception. When congenital malformation is present, the practitioner should be guarded in his prognosis. He may remedy webbed fingers and toes by dissecting them apart, but he will scarcely hope to see a congenitally malformed limb become perfectly developed. Umbilical Hemorrhage. If the umbilical cord be tied firmly with an aseptic ligature after its pulsa- tions have ceased, if the stump be powdered with boracic acid or salicylic acid 1 part to powdered starch 3 or 5, and if reasonable care be exercised to protect it from violence, haemorrhage from the umbilicus or umbilical inflammation 86 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. rarely occurs. The cord may be best protected by enclosing it in a small mass of antiseptic cotton, directing the extremity of the stump upward and to the child's right, and pinning a tlannpl binder comfortably tight about the abdo- men. In cases, however, where syphilis, hiBmophilia, septic infection, and acute fatty degeneration, with hcTemoglobinuria, are present, haemorrhage may occur when the cord separates, or even before that time. This complica- tion is not very frequent, Winckel having observed it but once in 5000 infants. Bouchut quotes Grandidier's analysis of 202 cases, from which he concludes that the hnemorrhage begins most often at night, and often accompanies colic, vomiting, somnolence, and jaundice, with ecchymoses of the skin. Bleeding occurs rather more frequently before the cord is entirely separated, and usually between the fifth and ninth days. The haemorrhage takes the form of arterial oozing, the blood often failing to coagulate. The haemorrhage may persist from one hour to several Aveeks. The mortality from umbilical haemorrhage is estimated at 80 per cent. The treatment is frequently futile. A needle, armed with a silk ligature, may be passed beneath the vessels and securely tied ; two surgical pins may be passed beneath the bleeding tissue at right angles to each other, and the ligature may be looped around the pins. Pressure is indicated in treating umbilical haemorrhage ; it is best made with antiseptic cotton on which iodo- form has been freely sprinkled. Umbilical Polyp. The umbilicus may fail to heal perfectly, and abundant granulations, bleed- ing upon touch, and polypoid growths may develop; they are best treated by the application of nitrate of silver or other suitable escharotic. Umbilical Hernia. A protrusion of the abdominal contents may accompany defective closure of the umbilicus. While it is indicated to palliate this condition by suitable dress- ings, yet it has been found possible to secure a radical cure by operation vei-y soon after birth. Runge describes a case operated upon successfully sixteen hours after birth. In the Tuajority of cases a cure may be effected, in a period varying from one to six months, by the application of an umbilical button. This consists of a hard-rubber disk convex on the applied surface, which is held in position by a broad band of surgeon's adhesive plaster. Gastro-intestinal Hemorrhage. This complication depends upon a purpuric condition, and manifests itself most frequently from the fifteenth to twentieth day after birth. Kiwisch reports cases of hasmorrhage from the intestinal tract following the normal birth of apparently well-nourished children. The first symptoms were dis- charge of blood and restlessness, occurring from twelve to thirty hours after labor. The abdomen became dull and tumid, the patients were pallid, and in some instances vomited blood ; death ensued within forty-eight hours. According to Grynfeltt, gastro-intestinal haemorrhages usually take place during the first three days after birth (Rilliet, Silbermann, Dusser), though in a case of this author's it occurred on the fourth and fifth days, and in two instances, seen by Rilliet, the children were fifteen and twenty weeks old. Sex seems to play no special predisposing role, but the influence of morbid INJURIES AXD DISEASES OF THE NEW-BOBN, 87 antecedents in the parents appears to be a factor of some importance. Pinard, Champetier. Auvard, and others have noted syphilis in the progenitors, hut this is regarded by Grynfeltt as only a cause acting indirectly in deterioratino- the health of the parents. Htemophilia has certainly been proven in some instances. The pathogeny is quite as obscure as the etiology. The lesions observed at autopsies are the most variable. Ulcerations of the stomach and intestines have been found ; again, only a simple congestion ; -svhile other cases have shown a complete absence of visible lesion. Grynfeltt advances a theory suggested by observations of Billard, and confirmed by personal studies of the histology of the digestive mucous membranes of new-born infants. These show that the vascular supply of the mucous membrane of the stomach and intestines is exceedingly rich at this period of life. Adding to this state of physiological congestion a congestion or impeded circulation in the liver, he finds it easy to ascribe the cause of such haemorrhages to exaggerated tension in the portal area. This view, he believes, is supported by the fact that these haemor- rhages, at first sudden and profuse, quickly cease, thus resembling a true depleting loss of blood. The first symptom is usually the hi^morrhage itself. Blood flows from the mouth following efforts at vomiting, or from the rectum, more or less mixed with faeces or in clots ; quite often both phenomena are coincident, hsemate- mesis being usually the earlier. When one alone occurs, h^matemesis is by far the more frequent. In spite of the gloomy prognosis evidenced by the statistics of Dusser (-iS deaths in 78 collected cases), a more hopeful view must be taken. In treatment, tannin in syrup of rhatany offers an efficient astringent potion. One and a half to two and a half grains of ergotin in mucilage are employed with satisfaction by Widerhofer of A'ienna. Icterus Neonatorum. The physiological icterus of the new-born infant appears on the third or fourth day of life, is characterized by a yellowish pigmentation of the face and breast, persists for about a week, and does not seem to disturb the patient's general condition at all. The urine is dark in color, containing bile-stuff, while the stools lack the color usually given by their mixture with bile. The cause of such icterus is thought by Birch-Hirschfeld to be swelling of Glisson's capsule, commencing at the umbilical vein, and by oedema preventing the free discharge of bile through the hepatic vessels: hence the jaundice is hepato- genic. Hofmeier thinks icterus is caused by the enormous number of red blood-corpuscles which are formed in the liver and hinder the production and discliarge of bile. The entrance of this coloring matter into the blood is furthered by catarrh of the duodenum and congenital stricture of the ductus choledochus. Halberstam found undissolved bile-stuff in the urine of children with icterus, and the epithelium of the kidneys infiltrated with the same coloring matter. The harmless character of this jaundice and its spontaneous disappearance should not make it a subject of anxiety to the physician or parents ; it some- times is due to slight changes in diet or any temporary disturbance of the child's general surroundings. Beyond the regulation of the bowels by the most simple laxatives, no treatment should be employed for this condition. Infective jaundice will be considered under the head of infections which attack the foetus. AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. The Infections attacking the New-born. The recognition of bacteria, ptomaines, and toxines as causes of disease has served to explain many disorders of the foetus and infant at birth not previ- ously understood. Most frequent of these infections are those by the micro- cocci of gonorrhoea and the streptococci of suppuration. Gonorrhoea in the mother affords the best of grounds for fearing gonorrhoeal infection in the new-born child. The most usual site of this infection is the conjunctiva, and ophthal- mia neonatorum is a familiar se(i[uence of maternal gonorrhoea. The treat- ment of this disorder Avill be considered in another section of this book. We are interested, however, in the practical prophylaxis of such infection : if the practitioner could be absolutely positive that the mother had never been infected by the gonococcus, prophylaxis would be entirely unnecessary. In hospital patients, however, there is always room for suspicion ; and in private cases, although there may seem no adequate reason to fear such a complication, yet its appearance will often surprise and disappoint the attending physician. No information will be gained in this matter from interrogating the patient : if she has ever been infected, her husband has certainly not told her the cause of the disorder, and her physician may have kept her in like ignorance. Furthermore, in women who have never been infected by the gonococcus there occurs at the latter portion of pregnancy a vaginal discharge which is capable of setting up a mild conjunctivitis in the infant. Hence a practical rule may be followed to advantage, that where a vaginal discharge persists during the latter portion of pi'egnancy the use of antiseptic douches is certainly indicated. These douches may be, preferably, creolin or bichloride of mercury : the first has the advantage of impairing the natural condition of the mucous membrane of the vagina less than does the mercurial ; it is also a safer substance to put in the hands of a patient. On the contrary, its odor is disagreeable to some, and when used in a stronor mixture it causes considerable irritation and burning. In a strength of one teaspoonful to the (|[uart the resulting mixture is seldom so irritating as to cause discomfort. The (quantity used should be not less than a quart, and the douche should be preferably taken while the patient is in the recumbent posture. The douche-bag should hang not higher than three feet above the patient's body, and the force of gravity alone should be employed in giving the douche. If bichloride of mercury be chosen, 1 : 5000 is sufficiently strong for such use. In patients admitted to hospitals, suffering from the effects of previous gonorrhoea or having acute gonorrhoea, the treatment must be more radical ; here a preliminary thorough cleansing of the vagina should be made with green soap and creolin, the mixture containing 2 per cent, of the creolin: following this, creolin douches, four times in twenty-four hours for the ten days preceding labor, will be found of advantage. Should the mudous membrane not tolerate such frequent douches, the vagina may be tamponed with iodoform gauze containing 50 per cent, of iodoform, and the number of douches be reduced one-half. In all hospital cases a preliminary douche of green soap and creolin may be used to advantage ; in pinvate practice a pre- liminary douche of bichloride, 1 : 5000, may also be employed to the advantage of mother and child. Aside from ophthalmia, gonorrhoea may infect the infimt at birth upon other mucous membranes. Rosinski describes the results of interesting inves- tigations made by him upon gonorrhoea occurring in the mouths of new-born infants. The lesions caused by this germ in the mouth develop only where the pavement epithelium has been removed. These cells are especially fragile PLATE III. Fig. 1. Fig. 2. Fig. 3. ^"^-_^ •^■■■■.1***^ Fig. 4. Gonorrhopa of the Mouth in the Newborn (Rosinsti). INJURIES AND DISEASES OF THE NEW-BOBN 89 in the young child, and hence the readiness with which infection occurs. It is interesting to note that in gonorrhoea! ophthalmia it is very rare to find that the lachrymal sacs become involved ; it is also true that the cylindrical epi- thelium of the naso-pharynx seems also to resist successfully invasion by the gonococcus. Clinical observation shows that these cases develop usually between the fifth and tenth day of life, resulting often from infection from th'fe genital canal, occurring at birth, and oftentimes through direct infection at the hands of attendants. This is especially true where the epithelium of the mouth is destroyed through efforts at cleansing. These cases are remarkable for the fact that they affect the general health so little ; the children nursing well and seeming free from pain. The lesions are yellowish plaques, surrounded by a border of pale-reddish tissue, in which the process of healing usually begins upon the third day by a reaction zone of deeper color. The epithelium is renewed from the borders of the plaque, pus-cells being thrown off as the healing progresses. Scar-tissue is never developed in these cases. The accompanying plate gives an excellent idea of the appearance of the lesions. (Plate III.) The treatment of gonorrhoea affecting the mouth of the new-born con- sists in careful avoidance of injury to the epithelium; the finger should not be inserted into the mouth of an infant suffering from this disorder : the affected surfaces should preferably be sprayed with a solution of hydrogen peroxide or a saturated solution of boracic acid. Such treatment is usually amply sufiicient to secure the recovery of the patient. The infant's general condition often requires attention in these cases, and its food and hygiene are matters of great importance. General Septic Infection. Streptococci, bacteria, and ptomaines of septic infection usually find entrance to the foetal body through the granulating surfaces upon the umbil- icus ; the result is arteritis and phlebitis of the umbilical vessels, resulting in the formation of thrombi and the infiltration of the surrounding tissues with bacteria and ptomaines. Both umbilical arteries are usually involved, the infection extending from the umbilicus to the bladder. The umbilical ring may ulcerate, or may have healed entirely while the infection has proceeded within the abdomen. According to Weber and Runge, the tissue about the arteries is usually first involved ; the iliac vessels and the retroperitoneal con- nective tissue usually escape ; in two-fifths of cases Runge found pneumonia or pleurisy with small metastatic abscesses. Peritonitis and pysemic metastases in the abdominal viscera and the joints have also been observed. In umbilical phlebitis the capsule of the liver and the liver itself become involved. Peri- carditis, pleuritis, and other pysemic complications are often present. The symptoms of such infection are often obscure. The umbilicus may become inflamed shortly after birth ; the child has fever, is restless, holds its legs and thighs flexed, and often becomes jaundiced. Death may occur in convulsions, but occasionally recovery ensues. The treatment of umbilical septic infection is largely prophylactic : thorough antisepsis as regards the physician, nurse, and external genital organs of the patient, a suitable and cleanly dressing for the umbilicus, such as previously given, and scrupulous cleanliness while the cord is drying and becoming separated, render umbilical septic infection a rarity. If the child be too feeble to have the full bath for the first month of life, it is comparatively easy to allow the cord to remain undisturbed. Where, however, the child is bathed daily in the bath-tub, such of the cotton as may 90 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. become wet should be carefully removed, the cord repowdered, and fresh cot- ton applied. The constitutional treatment of an infant suffering from septic infection through the umbilicus consists in the reduction of excessive fever by judicious sponging with Avarm or cool water, and the free administration of dilute alcohol and nourishing food. While quinine, if it can be taken, is a useful auxiliary, vet alcohol is the drug of most importance for such cases. Infants suffering from severe infections often bear strychnia as a stimulant better than might be expected from theoretical considerations only. Erysipelas. The micrococcus of Fehleisen may obtain an entrance at the umbilicus, and erysipelatous inflammation of the subcutaneous tind cutaneous tissues may result. This process may go on even to the extent of gangrene and sloughing of the affected parts. Cases of mixed infection resembling erysipelas may develop, complicated by diphtheria, as in illustrative cases reported by J. Lewis Smith from the records of the New York Infant Asylum. The infection may localize itself in multiple abscesses beneath the skin, or, extending to the peri- toneum, may cause death from acute peritonitis. The treatment of erysipelatous infection of the umbilicus and' surrounding parts consists in thorough applications locally of peroxide of hydrogen, boracic acid, or thymol solution, 1 : 1000. Following this, equal parts of iodoform and boracic acid may be employed freely. Wiien pockets of pus form, they should be promptly opened with a knife or scissors and thoroughly douched with an antiseptic. The child's general strength must be assiduously supported by alcohol, food, and strychnia or quinine. As a stimulant in severe prostra- tion, hypodermatic injections of camphor in oil, or administration, by the mouth, of freshly-made English breakfast tea, with rum, will be found of ser- vice in some cases. Acute Peritonitis in the New-born. Acute peritonitis occasionally arises very soon after birth as a complication of erysipelas or from some pathological process developing in the intestine. The communication in lymphatic channels between the intestine and the peri- toneum seems unusually free in the infant, and as a result peritonitis rapidly supervenes. Cassell describes three interesting cases of this sort. Lorain, Quinquaud, and Silbermann have also reported illustrative cases of this dis- order. Tubercular and Typhoid Infection. There exists certain ground for belief that the fatus in ntero may become infected by tubercle bacilli and also by the bacilli of typhoid. The first few days after birth may Avitness acute miliary tuberculosis or the development of a well-marked typhoid condition. As regards the former, the usual clinical signs of acute tuberculosis Avill be present : it must be remembered, however, that the infant rarely survives acute tuberculosis long enough for the formation of lung-cavities, and hence physical signs Avill often be lacking. The character of the fever, the rapid, uninterrupted course of the disorder, Avith increased dul- ness over the thorax, and the development of harsh and bronchial breathing, will usually enable the physician to make a diagnosis. INJURIES AND DISEASES OF THE NEW-BORN 91 While treatment up to the present time has been practically unavailing, it is of interest to note the experiments of Pinard in using injections of the serum of dog's blood in these cases ; in a series of twenty-one infants so treated he believes that benefit has resulted, the remedy seeming to act as a powerful tonic and stimulant. The intra-uterine transmission of typhoid infection is well illustrated by a case recorded by Giglio. The presence of the typhoid germ Avas demonstrated in the tissues of an apparently normal foetus and placenta born forty-six days after the beginning of typhoid fever in the mother. The treatment of typhoid in the new-born is practically that in the adult, reference being had to the ease with which the infant is stimulated or de- pressed. Tke prognosis in such cases is exceedingly grave. Inspiration Pneumonia, In prolonged labor, complicated by a septic condition of the mother's birth-canal, premature inspiratory movements on the part of the foetus may result in the inspiration of septic material : lobular septic pneumonia may result, and, occurring soon after birth, frequently proves rapidly fatal. Here, again, the efforts of the physician lie in prophylaxis, in delivering the patient promptly, and maintaining so far as possible an aseptic condition of the birth- canal until labor shall terminate. Tetanus. The infant may become infected with tetanus, and this disorder may appear in well-marked type from the sixth to the ninth day after birth. The tetanus bacillus usually finds its entrance at the unhealed umbilicus. Brieger has shown the specific cause of this disorder, and Beumer and Peiper have con- firmed by clinical observation the identity of trismus and tetanus of the new- born Avith inoculative and Avound tetanus. The mortality among infants is exceedingly large, and recovery is the rare exception. Appearing with symp- toms of restlessness, night- terrors, and frequent cries, the child often becomes nauseated, has slight diarrhoea, and is then attacked by trismus. This, at first intermittent, finally becomes persistent, and develops into tetanic contrac- tions of the entire body. Icterus is usually present. The disorder rarely lasts more than three or four days, the child perishing in collapse from twelve to twenty-four hours after the beginning of the convulsions. High temperature is usually present at the time of death. On post-mortem examination effusion of blood and serum in the cerebral tissues is frequently found. The violence of the convulsions may give rise to hgemorrhages into the muscular interspaces or into the tissues of the mediastinum. In treatment hydrate of chloral and alcoholic stimulants give most pros- pects of relief. Holt has reported a case which recovered under the free use of bromide of potassium. A specific method of treatment by the injection of a substance similar to tuberculin has not, so far as Ave know, yet been employed in this disease. There Avould certainly seem to be reasons for testing its value. Mastitis. Mastitis in the new-born infant is to be regarded as a mild septic infection when the disorder comes to the point of suppuration and phlegmonous inflam- mation. The mammary glands of neAv-born children frequently become engorged and tender, but this condition subsides if the glands be let alone and 92 A3IERICAN TEXT-BOOK OF DISEASES OF CHILDREN. protected from external violence. When, however, infection occurs, pus- formation nvAy take place and a septic mastitis may result. Such a compli- cation, however, is exceedingly rare where antiseptic precautions are habitually taken in the treatment of labor cases. A distinction must be made clinically between simple engorgement of the breast and infection. In the former the child's temperature remains but little disturbed, its appetite is unimpaired, its rest remains practically as before. If the glands be carefully but gently washed with soap and water and bathed with bichloride, 1 : 10,000, a thin layer of absorbent cotton put over them, and a soft flannel bandage pinned snugly about the breast and supported over the shoulders by shoulder-straps or some other simple device, the glands may remain undisturbed for several days unless fever or restlessness indicates inflammation. On the other hand, where infec- tion is present and pus has formed, prompt emptying of the gland by incision, , with disinfection of the cavity, is indicated. Infections of the Blood. Profound alterations of the blood and nutritive cellular processes in the new-born, the probable result of infection at birth, have been described under various names by diff"erent observers. Hecker and Von Buhl describe a disorder of infants born in asphyxia characterized by cyanosis, vomiting, icterus, profuse parenchymatous haemor- rhage, accompanied by acute fatty degeneration of visceral epithelium and heart-muscle. Phosphorus- and arsenic-poisoning were excluded in diagnosis, and the malady was named "acute fatty degeneration of the new-born," or Buhl's disease. Its pathology is not perfectly explained, but it may be classed among the infective disorders resulting in the extensive disintegration of the blood. Acute hpemoglobinuria of the new-born was first clearly described by Winckel, who reported twenty-three cases of the disorder. It is characterized by swelling of Peyer's patches and the mesenteric glands, blackish-red staining of the pyramids of the kidneys, with stripes of hfemoglobin coloring, fatty degeneration of the liver and other viscera. Hematogenic icterus is present, the hi^moglobin being extensively changed into bilirubin. The urine is dark brown-reddish in color, contains htemoglobin, epithelium, casts, and micro- cocci." Chemical poisons as a cause were excluded in diagnosis. The mothers showed no infection, the children were usually well developed. The mortality was 19 out of 23. The cause of the disorder is not clearly demonstrated. It is undoubtedly an infection which attacks the blood, resulting in hsemoglo- biniBmia. Prophylaxis and treatment, beyond the faithful employment of antiseptic precautions, are practically without avail. Hsematogenic jaundice, accompanied with multiple oozing of blood, has been recently described in an interesting paper by Partridge. In the case reported recovery ensued. In 1166 infants born at the Nursery and Child's Hospital, New York, 11 cases of haemorrhage occurred, with a mortality of 75 per cent. At the Sloan Maternity Hospital, in 850 patients there were 14 cases ; mortality over 60 per cent. No intelligent family history of bleeding was obtained. Somewhat similar to these cases are those of the disorder known as Mel^na Neonatorum. Infants dying with profuse haemorrhage from the stomach and intestine have revealed an ulcer of the duodenum as a cause. In explaining these phenomena INJURIES AND DISEASES OF THE NEW-BOBN 93 Landau assigns as a cause thrombosis of the umbilical vein, resulting in em- bolism in the vessels of the stomach and duodenum. Persistence of the ductus arteriosus and haemophilia also have been assigned as causes. Kundi'at in exam- ining Winckel's case found excessive secretion of the gastric juice, Avhich had partly digested the mucosa of the intestine and occasioned haemorrhage. In other cases bloody stools and vomiting of blood persisted for several days. Recovery occasionally ensues. The prognosis is exceedingly grave, and treatment is practically unavail- ing. The milder preparations of iron may be given by the mouth, and hot or cold applied to the surface of the body as the condition of the child indicates. An abdominal compress may also be useful. In closing this consideration of the infective disorders of the new-born we must again emphasize the fact that while we are not, in the present stage of our knowledge, in a position to particularize regarding the precise nature of the infective agent and its mode of operation, still, the fact remains reasonably proven that these cases result from some direct infection occurring just before or during birth. It remains, then, the positive duty of the practitioner to see to it that rigid asepsis — and, better, antisepsis — is employed regarding his hands and instruments, those of the attendant, and also the external organs of the patient. Ehrendorfer, writing upon this subject, draws attention to the dangers of infection, not only from mother to child, but from one child to another in hospital wards. The practice of putting a number of children in the same crib is objectionable, as is the custom of bathing a number of children in the same bath-tub, and, still worse, of using the same towels or cloths for a number of baths. From the moment of birth each infant should have its own toilet appliances, be they of the simplest description. In cleansing the child absorb- ent material which can be thrown away and not used a second time is prefer- able. Separate vessels for bathing the child's body and for washing the head and face are also desirable. In this way septic matter from the umbilicus is kept away from the mouth and eyes, and vice versa. Nurses may be drilled to advantage in these niceties in the care of infants, which are not simple matters of aesthetic neatness, but are founded upon " pathological facte. PART II.

General Etiology and Morbid Anatomy. {a) IxciDEXCE OF Tuberculosis in Infancy axd Childhood. — Although it has long been known that, in the quaint language of Sir Thomas Browne, "consumptive and tabid roots sprout early," the appreciation of the wide- spread prevalence of tuberculosis in the early periods of life is due to recent observations. Extremely rare in the new-born and uncommon in the first three months of life, the cases increase rapidly throughout the latter half of the first year and in the second year. In the creche of the Hopital Tenon of Paris, in the year 1890, it is stated that more than 21 per cent, of the babies died of tuberculosis. Of 2576 autopsies on infants made at Kiel, Boltz found 424 cases of tuberculosis. The following table gives the proportions at different ages: Infants born dead .... 0.0 per 100 From to 4 weeks . . . 0.0 " . " 5 " 10 " ... 0.0 " " 3 " 5 months . . 8.6 " " 6 " 12 " . . 18.3 " " 1 " 2 years . . . 26.8 " The Statistics of the late Professor Parrot embraced 219 cases in children under three years. Of these there were — From 1 day to 3 months 23 " 3 to 6 months 35 " 6 " 12 " 53 giving a total of 111 under one year of age, and from one to two years, 108. Of 500 autopsies in children at the Munich Pathological Institute, Miiller found tuberculosis in 150. Of 527 infants dead in hospital of various diseases, tubercles were present in 314. A set of combined autopsies on 2230 children gave 753 tuberculous and 1407 non-tuberculous. The ages of the tuberculous cases are thus grouped : From birth to 1 month 10 Up to 2.y years 138 From 3 to 5 years 255 " 6 " 10 ' " 226 " 11 " 15 " 124 94 TUBERCULOSIS. 95 Analogous statistics are not, to my knowledge, available in this country, but the observations of Northrup at the New York Foundling Asylum show, at any rate, that the disease must prevail quite as extensively. From the third to the fifteenth year tuberculosis is also very frequent, and its manifestations in the glands, skin, and bones contribute a very considerable percentage of all cases in the out-patient departments of hospitals and in the special infirmaries for children's diseases. The mortality, highest in the first year, sinks rapidly throughout childhood, to rise after puberty. Thus of 10,000 living, there die(U. S. Census, 1870) of tuberculosis in the first year 18.5 ; in the second, 10.5 ; in the third, 5.9 ; from the third to the fifth, 2.9; from the fifth to the tenth, 2; from the tenth to the fifteenth, -3.3. The Kiel mortality statistics (Hellei') also show this in a striking manner: of 10,000 living, there died in the first year 245; in the sec- ond, 114; in the third, 76; from the third to the fifth, 34; from the fifth to the tenth, 14; from the tenth to the fifteenth, 16. (h) The Bacillus Tuberculosis. — It is acknowledged by those most capable of expressing an opinion that the essential cause of tuberculosis is the organism discovered by Koch. The bacillus is a short, fine rod from 1 to 5 // in length, and usually a little curved. In the sputum and in tuberculous tissue the bacilli are often in little clumps, or two lie crosswise at an acute angle. For demonstrating the bacilli in sputa the following method will be found satisfactory : The thicker and more purulent parts of the sputum are picked out with a small sharp-pointed forceps and spread over the cover-glass, which is allowed to dry in the air and then passed three or four times through the flame. A few drops of Ziehl's solution of fuchsin — namely, distilled water 100 grams, carbolic-acid crystal 5 grams, alcohol 10 grams, fuchsin 1 gram- are placed upon the cover-glass, which is held over the flame until it begins to boil. The glass is then washed in water, and a few drops of Gabbet-Ernst's solution — namely, methylene blue 1 to 2 grams, 25 per cent, sulphuric acid 100 grams — are placed upon the glass and allowed to remain there for about a minute. The glass is then washed in water, and mounted either in water or, after drying between filter-paper, in oil or balsam. The tubercle bacilli are stained red, while the nuclei of the cells and any other bacteria are stained blue. In sections the following method is pursued at the Pathological Laboratory of the Johns Hopkins Hospital: The tissues should be hardened in absolute alcohol and imbedded in celloidin. After the sections have been cut, the cel- loidin should be removed either with oil of cloves or with absolute alcohol and ether. After this they are passed through strong alcohol (to remove the oil or ether), and then placed in water previous to staining. The most satisfactory dye is the carbol-fuchsin solution of Ziehl. The sections are left for two hours at a temperature of 60° C. (or, if this be inconvenient, they may be stained for six or eight hours in the thermostat at 37° C, or for twenty-four hours at the room temperature). The tissue-elements and the bacilli are thus stained deeply in the fuchsin. A good decolorization solution is the ordinary acid alcohol of the laboratory (acid, hydrochloric. 1, aq. destill. 30, alcohol 70). The decolorizing process must be carefully watched, as too much of the dye may be easily extracted, the tubercle bacilli along with the tissue-elements losing their stain. It is best to remove the sections from the acid alcohol while they still retain a decided pink tint. A counter-stain is then used, the most desirable being a 2 per cent, aqueous solution of methylene blue. This removes all remaining fuch- sin color from the tissue-elements and stains them a delicate blue. The tuber- 96 AMEBIC A^"^ TEXT-BOOK OF DISEASES OF CHILD REX. cle bacilli are stained a bright red. The sections are to be dehydrated in abso- lute alcohol, cleared in oil of cloves or preferably in xylol, and mounted in xylol balsam. It is best to examine with an oil-immersion lens, although if the bacilli are numerous they can readily be made out with a good high-power dry lens (Zeiss 3, or Leitz 7). Tubercle bacilli may be demonstrated in tissues by means of the rapid method used for staining them in sputum, but the results are very unsatisfactory, owing to the distortion of the tissues resulting from the action of the heat and the strong acids. The bacillus is aerobic, and, although somewhat difficult to cultivate, may be frown on blood-serum, glycerin agar, or even on potato. The colonies form dry, grayish-white, scale-like masses. In the growth the bacillus forms certain soluble product or toxines, which, if introduced into the body, produce lesions similar to those induced by the bacilli themselves. The bacilli are tolerably tenacious, and retain their virulence after freezing, desiccation, and salaison. It is stated that the bacilli have been found alive after burial of the subject for two years. The combined action of dryness and exposure to air is stated to diminish the virulence, but tuberculous sputum exposed to the air for from fifty to one hundred days still retains its virulence. The bacilli are rapidly killed in a few minutes by moist heat, as in boiling; dry heat is much less effectual. The bacilli are found in variable numbers in all tuberculous structures — the acute miliary nodule, the caseous, fibrous, and fibro-caseous nodules. They are most abundant in rapidly-growing tubercles and in the old ulcerous lesions of pulmonary tuberculosis. They are scanty, as a rule, in the more chronic tuberculous processes of glands and of bones, and in the lesions associated with extensive caseation. When not easily demonstrable by histological methods, inoculation in animals may alone determine the tuber- culous nature of a structure. Outside the body the bacillus has been shown to be a very widely-dis- tributed organism, the number in any locality depending upon the number of cases of pulmonary tuberculosis and the carelessness or thoroughness with which the sputa of infected individuals is destroyed. In an ordinary case of pulmo- nary consumption countless millions are thrown out daily and scattered widely in the sputum dried as dust. Cornet found the dust of hospital wards and places occupied by tuberculous patients to be infective in a number of cases. Thus of 118 samples of dust from the wards of hospitals and rooms occupied by tuberculous individuals, 40 proved capable, when inoculated in animals, of producing tuberculosis. The infectiveness of the dust of the medical and sur- gical divisions of a hospital w^as found to be in the proportion of 76.6 to 12.5. {c) Modes of Transmission. — (1) Experimental Tuberculosis. — Much of our knowledge of the disease has been derived from experiments, and we owe to Yilliman the demonstration of the infective character of all tuberculous pro- cesses. The receptivity of animals varies very much : the rabbit and guinea- pig are particularly susceptible ; dogs and cats are very resistant. Bovines are very susceptible, and one of the most important facts in the etiology of the disease is the frequency with which the disease occurs in them. Subcutaneous inoculation of tuberculous material in a susceptible animal, as a rabbit or a guinea-pig, is followed in a short time by the production of a little nodular growth, which softens, and even ulcerates, and which in time may be absorbed. The corresponding lymph-glands swell, tubercles develop in them, and then caseate. The animal dies in from six weeks to three months. Tubercles are found in the lymph-glands, and there is, as a rule, general tuber- culosis of the organs. The most satisfactory method is the inoculation of o to 1 1 2, O 3 H '^ 5- 1 life' ^ -2^ f J. ;^ ; ^ ^' -%,,,iiii' -/^ ^t -^ > /^:rT% ^^ -t V 4 TUBERCULOSIS. 97 material into the anterior chamber of the eye of the rabbit, as used by Cohn- heim. The development of the tubercles, at first a local process, may be watched in the iris. There is afterward generalization, and the animal dies emaciated. In some instances in the rabbit and guinea-pig the lesion produced is entirely local and the animal recovers. If a culture of tubercle bacilli is injected into the veins, the animal dies, as a rule, in a shorter time, with the development of miliary granulations, particularly in the liver and in the spleen. If a larger quantity be injected, the animal may die of a profound infection before the tubercles become visible to the naked eye. The transmission by inhalation is more difficult in animals, and the results of causing animals to breathe air charged Avith tubercle bacilli are discordant, but in some instances undoubted pulmonary infection and general tuberculosis have folloAved. Experimental infection through the digestive passages has also been demonstrated, particularly in the feeding of animals with the milk of tuberculous cows. (2) Hereditary Transmission. — Current opinion on this point may be ex- pressed as follows : While in a few rare cases tuberculosis is transmitted directly from parent to offspring, in the great majority of all cases the heredity does not relate to the transmission of the seed itself, but of a disposition of body, a type of tissue-soil favorable to the development of the disease in case of acci- dental infection. Congenital tuberculosis has been observed in some six or eight cases. In the case of Chrrina there was generalized tuberculosis in a foetus seven and a half months old, the mother of which died of phthisis. In Berti's case the child, born at term of a phthisical mother, died on the ninth day, and two small cavities were found at the posterior border of the lower lobe of the right lung, which were shown microscopically to be tuberculous. In Merkel's case the tuberculous mother died two days after confinement. The child had tuber- culosis of the palate and an abscess of the left trochanter major. In Jacobi's case the foetus, born at the seventh month, had miliary granulations in the liver, peritoneum, spleen, and right pleura. In the case described by Sabour- aud the child born of a tuberculous mother died on the eleventh day. The liver and spleen were tuberculous. In all of the cases reported it was direct maternal heredity. The mode of transmission is not at all certain, but it is probably transmission through the placenta. Tuberculosis of the placenta is very rare. Lehman has recently reported an instance in a woman aged twenty-nine dead of acute tuberculosis in the eighth or ninth month of pregnancy. The foetus was not affected, but on both surfaces of the placenta there were a few grayish nodules, which showed the characteristic structure of tubercle, with bacilli. It has been shown also that the placenta of a tuberculous woman proved infective ; and, indeed, it is stated that the amniotic fluid of a tuberculous subject may produce the disease in a guinea-pig. There are several experiments (Landouzy and Martin, Birch-Hirschfeld, and Armanni), which indicate that the virus may be present in the foetus without the presence of actual tubercles, since they found that portions of the viscera of foetuses born of tuberculous mothers were infective to guinea-pigs. A modified view of this direct heredity is advocated by Baumgarten, who holds that the virus is directly transmitted, but remains latent, and does not develop until some time after birth. In support of this he quotes the large number of cases of tuberculosis in the early months, the figures illustrating which have already been given. He also lays great stress upon the occurrence of tuberculosis in the bones and the joints of children, regions to which the 7 98 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. bacilli would not be likely to be conveyed in accidental infection. This post- natal development he regards as analogous to si/philis hereditaria tarda, and he sufTfrests that the actively growing tissues of the child restrain or inhibit the development of the germs. There is no evidence to show that a tuberculous father can directly trans- mit the disease. The experimental evidence is also negative. Gartner (whose recent article on "Heredity in Tuberculosis" is the most important contribu- tion made to the subject of late years) found that in rabbits and guinea-pigs, with artificially induced tuberculosis of the testes, and whose semen contained bacilli, the embryos were never infected. On the other hand, of 65 female guinea-pigs which had consorted with the tuberculous bucks, 5 presented genital tuberculosis, and of 59 female rabbits under similar conditions 11 became infected. In support of the view that tuberculosis is hereditary great stress is laid naturally on the frequency with Avhich a history of the disease is met with in the parents. The estimates of various authors on this point vary from 10 to 50 per cent. Of 427 cases at the Johns Hopkins Hospital, there were only 53 in which the mother was affected, 52 in which the father had had tuberculosis, and 105 in which sister or brother had had the disease. The fact that the children and relatives of tuberculous individuals are more directly exposed to contagion than other individuals render it difficult, as Fagge remarks, to draw a clear line between heredity and accidental infection. (3) Inoculation. — This is not very common in man, as the skin does not offer a very suitable soil for the development of the tubercle bacilli. This mode of infection is, however, seen in persons whose occupations bring them in contact with dead bodies and animal products. Demonstrators of anatomy are particu- larly subject to a local tubercle on the finger or back of the hand — the so- called post-mortem Avart, verruca necrogenica, the "lichen" tubercle of the Germans. Only in very exceptional instances is this followed by serious results. Cases have been reported of infection from the bite of a tuberculous patient, inoculation from a cut by a broken spit-cup and the puncture of a hypoder- mic needle. There is no reliable observation of the transmission of tubercu- losis by vaccination. In the performance of the rite of circumcision children have been inoculated, the infection in these cases being associated with disease in the operator, and occurs in connection with the habit of cleansing the wound by suction. (4) Transmisnon by Inhalation. — The expired air of tuberculous patients is harmless, but the sputa, dried and widely diffused in the form of dust, con- stitute one important medium of transmission in the disease. The investi- gations of Cornet have shown the greater infectiveness of the dust of localities frequented by patients with pulmonary tuberculosis. The frequency with which the disease is met with in the lungs and in the bronchial glands finds here its explanation. In institutions the residents of which are restricted in the matter of fresh air and exercise, as in jails and convents, the death-rate from tuberculosis is very much higher than in the general population. Cornet found that in some of the religious communities more than three-fourths of the deaths were due to this disease. The mortality in prisons from tuberculosis is from 40 to 50 per cent., while in the general community it is not more than 15 per cent. Flick has brought forward evidence to show that the distribution of tuberculosis in one of the wards of the city of Philadelphia is more particularly with certain houses in which individuals have died of this disease. There are also some striking local epidemics of tuberculosis: thus Marfan gives an instance of a TUBEBCULOSLS. 99 place confined and badly ventilated, occupied by twenty-two employees, Avho were joined in 1878 by two consumptives, who for several years coughed and spat about the floor indiscriminately. The employees arrived at an early hour and breathed the air charged with the dust raised by the morning cleanino-. Between 1884 and 1889 thirteen of these persons fell victims to tuberculosis. Against these facts, however, are the statements that at hospitals for con- sumptives, as at Brompton, in London, the doctors and nurses are rarely attacked. Dettweiler claims that at his institution in Falkenstein no case of" tuberculosis has been contracted. On the other hand, Marfan states that in the Paris hospitals tuberculosis is extremely frequent in the attendants and decimates the lay contingent. At the Hospital Necker half of the attendants are attacked with phthisis, and he notes as a significant fact that it is particu- larly the attendants in the medical wards. The danger is enhanced when the contact is particularly intimate, as between a tuberculous mother and her child or between man and wife. In the latter case there are figures which indicate that contagion is not at all infrequent. (5) Trcmsmission hy the Food. — Experiments have shown that infection may be communicated by ingestion of tuberculous material, and one of the most important problems relates to infection with the milk of tuberculous cows. Experimentally, it has been conclusively demonstrated that such milk is infec- tive, even when the disease is localized in the lungs of the animal, and that it is not necessary that the udder should be diseased. Ernst has shown that the bacilli may be present in the milk when there is no tuberculous mammitis. The danger of infection from this source in children is very urgent, and system- atic sanitary inspection should be made of the cows, and, if necessary, inocu- lation experiments made with the milk. The percentage of tuberculous animals in the dairy-stables of our cities is very much larger than has been supposed. The figures in this country for large numbers are not available. It has been stated that from 10 to 15 per cent, of the dairy stock in the Eastern States is tuberculous. This is probably a low estimate. The virulence is retained in the cream and in the butter. Other conditions than the presence of the bacilli in the milk are probabl}'' necessary for infection, and, fortunately, all children who drink tuberculous milk do not become con- taminated. In some instances the gastric juice may destroy the bacilli ; in others, conditions of the tissues may not be favorable to the development of the seed. Experimentally it has been shown that lesion of the intes- tines itself is not necessary, and infection of the mesenteric glands may take place through a normal mucosa. Possibly the great frequency of mesenteric tuberculosis in children finds here its explanation. In 127 cases of fatal tuber- culosis in children noted by Woodhead these glands were involved in 100. It is not definitely determined whether the milk of a tuberculous woman is viru- lent. Infection by meat is probably very much more rare. When the tuberculosis is generalized in the internal organs the flesh should be confiscated. The viru- lence, however, is only marked when the disease is very extensive. It has been shown that the flesh of tuberculous subjects is infective to guinea-pigs. Nocard, however, in a series of experiments found that the juices of the muscle of twenty-one cases with general tuberculosis, when injected into the perito- neum of guinea-pigs, only once produced tuberculosis. {d) CoNDiTioisrs iNFLUEJfCiNG INFECTION. — (1) Greneral. — These, dealing specially with the environment of individuals, explain in a great measure the 100 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. frequency of the disease in certain localities. Thus one of the most important is residence in the large centres in which many people are crowded together. The death-rate from tuberculosis is vei*y much higher in towns than in the country, and a very considerable share of the high infant mortality of cities is to be attributed to it. Not only is the air of the large towns less pure, but the chances are very much greater that the dust, blown in all directions, has with it the germs of the disease. The inhalation of impure air in certain occu- pations, which in adults is an important predisposing factor in pulmonary tuber- culosis, does not prevail to any special extent in children. Climate in itself does not influence the conditions matei'ially, but, as a rule, the disease is more common in the temperate regions, largely because in these are found the largest collection of human beings. Soil and locality have an important influence, cold and dampness increasing the personal liability by favoring the develop- ment of catarrhal affections. There are fewer cases of tuberculosis and fewer foci of infection in regions such as the Alps and in elevated plateaux as in Mexico, but altitude itself does not confer immunity, and there are many mountainous regions in which the inhabitants are much affected by tuberculosis. More important than these are the factors relating to personal environment, as of the dwellings. The constant breathing of a vitiated air, as in the small crowded rooms in the tenements and narrow alleys of our large cities, and the absence of sunlight, are tAvo of the most important predisposing elements in tuberculosis in children. These influence infection in two ways : first, by favoring the distribution of the bacilli ; and, second, by lowering the nutrition of the individual and leading to conditions favoring the entrance of the bacilli to, or their development in, the body. (2) Individual Predisposition. — From the time of Hippocrates it has been thought that there was a certain conformation of bodv which rendered an indi- vidual more prone to the disease. His words are : " The form of body peculiar to subjects of phthisical complaints was the smooth, the whitish, that resem- bling the lentil ; the reddish, the blue-eyed, the leuco-phlegmatic ; and that with the scapulae having the appearance of wings." In children it may be said that the build and type such as here described is certainly more prone to tuber- culous affections. Two types of conformation have long been recognized as predisposing in some way to infection ; the tuberculous, with bright eyes, oval face, thin skin, and long thin bones, and the scrofulous^ with a heavy figure, thick lips and hands, opaque skin, and large thick bones. But, as in adults, well-developed, healthy infants and children may become subject to the disease. In addition to the conformation of the chest, the respiratory capacity, the rela- tion between the volume of the lung and of the heart, a relatively small heart with narrow arteries, and a pulmonary artery relatively wider than the aorta (Beneke), and relatively large-sized viscera, have all been brought forward as causes predisposing to tuberculosis. Among others which may be mentioned is race : the negro seems more liable to the disease than the white races, and it is stated that the Hebrews possess a relative immunity. More important in children are the local conditions influencing infection. Acute and chronic catarrhal troubles of the throat and upper air-passages, and of the lung, undoubtedly favor infection, either by allowing the freer entrance of the germs or by weakening the powers of resistance. The infectious diseases, particularly whooping-cough, measles, and influenza, act probably in this way, while small-pox, typhoien air and sunshine. Even in cities much can be done by insist- ing upon open windows night and day, except, of course, in the very inclement seasons. It is an easy matter to protect the patient from draughts, and neither fever, cough, nor night-sweats contraindicate in any way fresh air. This is in reality the very essence of the climatic treatment of tuberculosis ; that other considerations, such as moisture, barometric pressure, temperature, etc., are secondary is well shown by the fact that cases of various types of tuberculosis recover completel}^ at places so diametrically opposite as Colorado Springs and Torquay. The regions of high altitudes with low barometric pressure are cer- tainly more stimulating, and, according to Jaccoud, are better for cases of early pulmonary tuberculosis. Cases of bone and gland tuberculosis do remarkably well at the Adirondacks and in Colorado. The level regions with low barometric pressure, such as Riviera, Florida, and Southern California, are reputed to be more sedative in their action and better for tuberculosis in the more advanced grades and with high fever. The second important measure is feeding, and the outlook in any case, par- ticularly of pulmonary tuberculosis, depends very much upon the stability of the digestive powers. In no way does the open-air treatment do more good than in improving the appetite and digestion. A highly nitrogenized diet, consist- ing of broths, eggs, milk, and meat, should be taken. In children the milk TUBEBCULOSLS. 125 diet is particularly to be commended Avhile fever persists. RaAv meats scraped, various meat extracts, and peptones may be used "when the digestion is feeble. In tuberculous children it is sometimes extremely difficult to manage the diet, and many patients have an aversion to the very articles of food "which seem best adapted. Gavage can rarely be resorted to with any advantage in them. Third, the use of such remedies as cod-liver oil, hypophosphites, and arsenic, which improve the general nutrition. Other measures are frictions, rubbing, and bathing, all of which stimulate and improve the general metab- olism. Treatment directed to the Tubereidous Processes. — The specific treatment by the tuberculin of Koch, which consists of a glycerine extract of the cultures of tubercle bacilli, has been practically abandoned, though the good results obtained in the hands of Trudeau and others with Hunter's modification raise the hope that something yet may be accomplished by its use. Anti- bacillary medication is as yet unknown, and the introduction of various anti- septic agents by inhalation, subcutaneously, or directly into the local lesion has not been followed by very brilliant results. The direct action of iodoform on local tuberculosis is of great interest, and the remarkable effects in joint tuberculosis should encourage a more widespread use in other forms of the disease. Creasote is a remedy which is believed to have a beneficial action on the tuberculous processes. It probably has no definite antibacillary action, though it is stated to influence powerfully the secondary and associated infec- tions so common in tuberculosis. It seems rather to act as a general nutritive stimulant, improving the appetite, diminishing the fever, and promoting tissue- metabolism and, according to some, sclerotic processes. It is probably at present more widely used than any other single remedy. It has been a favo- rite with some practitioners for many years, and its reintroduction has been due to the powerful advocacy of Sommerbrodt, Bouchard, and others. It should be given in large and increasing doses, beginning in young children with a minim three times a day, and increasing to five or even ten minims. It may be given in perles, or in pills or in mixture ; in the latter a convenient way is with tincture of gentian, alcohol, and sherry. As a rule, it is well borne by the mouth. It may also be given in the form of inhalations, the so-called vapor creasoti consisting of creasote, 80 minims, light carbonate of magnesium, 30 grains, water to one ounce ; a teaspoonful in a pint of water at 140°. Inha- lations with this are strongly recommended. Intrapulmonary or intratracheal injections of creasote in oil have been practised. The active principle of it, guaiacol, has been much used, both by the mouth and hypodermatically. Given in solution, it may be made up with tincture of gentian, rectified spirits, and sherry. Hypodermatically, it is used with sterilized olive oil, 5 per cent, solution ; 1 or 2 per cent, iodoform may be employed with it, and 1 cc. of the mixture injected, gradually increasing to 3 cc. or even 4 cc. One rarely sees bad effects from creasote : the beneficial results are most marked in indi- viduals who can take large quantities and who can enjoy the associated action of fresh air and a good diet. Creasote without these accessories is not of very great service, as witnessed in ordinary hospital practice. Patients are remarkably tolerant of it, and one rarely sees any ill effects. Other balsamic substances, such as eucalyptol, terebene. terebinthine, thymol, and menthol, have been recommended. Symptomatic Treatment. — In this we shall refer more particularly to pul- monary tuberculosis. The fever of tuberculosis is serious and obstinate. It will be found in the early stages that the combination of rest with fresh air is the most beneficial. 126 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. The child may be wrapped up and taken into the fresh air for the greater part of the (hiy. We have no thoroughly satisfactory medicinal means for reducing the temperature. AntipA'rine, antifebrin, and acetanilide, if used at all, must be given with great care. Quinine and salicylic acid are still used by many practitioners. When the temperature is persistently high in the early stages of tuberculous broncho-pneumonia, cold in various forms will probably be the most efficient measure, and by careful sponging the temperature may be reduced several degrees. The most satisfactory antipyretic is found in the fresh air, more particularly the change to a resort such as the Adirondacks or Colorado. In the chronic pulmonary tuberculosis of children, when the fever is of a hectic type, sweating is a very troublesome and disagreeable symptom, for which atropine, aromatic sulphuric acid, and tincture of nux vomica may be used. In young children great care .should be taken to prevent the chilling of the body after a profuse night-sweat. For the cough, if troublesome at night, paregoric or small doses of Dover's powder may be used. Codeine or, in extreme cases, small doses of morphine may be given. AVhere there is marked tenderness on the chest or pleuritic complications the cough is sometimes relieved by mild counter-irritation or the application of a warm poultice. Inhalation of terebene and oil of eucalyptus may sometimes diminish the profuse expectoration, Hiemoptysis in the pulmonary tuberculosis of young children is usually a terminal and fatal symptom, quickly beyond treatment. The diarrhoea may demand very careful regulation of the diet, and if pro- fuse the acetate of lead, alone or with opium, may be used. Preparations of tannin and gallic acid are also beneficial. In all tuberculous processes there is a more or less marked tendency to anremia, and many patients improve quickly under the administration of iron. Careful attention should be paid to the gastric symptoms. If the digestion is poor, dilute hydrochloric acid may be used, and if heartburn and pain be present some time after eating, the carbo- nate of sodium or the alkaline mineral waters. HEREDITARY SYPHILIS. By henry DWIGHT CHAPIN, M. D., IS'ew York. No period of life is exempt from syphilis, -which has been aptly styled "the least venereal of the venereal diseases." It is a chronic infectious pro- cess, doubtless of microbic origin, the ravages of which are modified by age, conditions of body, and environment. The micro-organism most commonly associated with syphilis as a probable causative agent has been found by Lust- garten within the cellular protoplasm of syphilitic products. He describes it as a bacillus from three to seven micro-millimetres in length, with often a slightly wavy shape. Unfortunately, pure cultures have not been made of this bacillus, and the fact that the lower animals do not contract syphilis pre- vents the possibility of proof by inoculation. Syphilis in early life may be either hereditary or acquired. It is not neces- sary to consider acquired syphilis at length in a work devoted to diseases of children, as it presents no essential differences from the same afiection in adult life. It may be well to bear in mind, however, that syphilis detected in infancy is not necessarily inherited, but may be acquired. A primary sore upon the genital tract of the mother may infect the infant during birth, though the possibility of this has been denied. The nurse or attendant may have a primary lesion upon breast or lips. Much more common will be infection from some secondary lesion, especially a mucous patch upon the mouth or lips. There are many ways in which the blood or infective secretions of a syphilitic patient may come in contact with a solution of continuity in the skin or mucous membranes of an infant or child. In such a case a chancre will appear at the point of contact, followed in due time by the after-lesions of the disease. There are certain peculiarities in the effect of the syphilitic virus upon young proto- plasm which will be noted under the Morbid Anatomy. The subject will be here considered under the two heads of hereditary syphilis in infancy, and the taint as it is seen in childhood or when appar- ently delayed. Hereditary Syphilis in Infancy. The disease may be acquired from the father or mother, or from both parents, the poison being lodged in the spermatozoa of the male or the ovum of the female. Paternal Influence. — While it has been denied by some observers that the father alone can transmit syphilis, the consensus of opinion is in favor of the possibility of such transmission, which can and does take place. The chances of this transmission depend upon certain factors, such as the stage of the disease and the degree of its intensity, as well as the thoroughness with which treatment has been followed. Without mercurial treatment the sperma- 127 128 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. tozoa can usually transmit the syphilitic poison during the first year after pri- mary infection, and there is great danger to the foetus from syphilitic contagion up to the fourth year. The longer the duration of the disease, the less will be the danger to the offspring, owing to the periods of latency observed during its later stages. If the father be subjected to early and thorough treatment, the probability of transmission of the disease will be much lessened, and such a possibility soon becomes lost with a reasonable lapse of time. If the father infect the mother, as frecjuently happens, there will be a double syphilization of the offspring, which will probably be stillborn or soon succumb to an aggra- vated form of the disease.^ Maternal Influence. — The influence of the mother upon the growth and development of the fcetus contained within her uterus is obviously very great, and hence when she is suffering from constitutional syphilis the disease is transmitted in an active stage to her child. The degree of such transmission depends, as noted above in the case of the father, upon the stage and severity of the disease and the nature of the treatment employed. During periods of latency the mother may bear healthy children, followed by abortions or syphi- litic infixnts caused by renewed manifestations of the disease. It has been con- sidered that the power of transmission is practically lost at the end of six years. As a general rule, it can be stated that the chances of infection of the foetus and the severity of the type, if infected, are in direct proportion to the activity of the syphilis in either or both parents. It has been said that if the mother contract syphilis before the eighth month of utero-gestation, she may transmit the disease to the foetus, although healthy at the time of conception. Dr. Taylor, on the contrary, denies that the syphilis of the mother, acquired during pregnancy, can be conveyed to the foetus through the utero-placental circulation, as the disease is only communicated either by the sperm-cells or by the ovule diseased at the time of conception. One of the peculiar phenomena seen in connection with infants who are born syphilitic is that the mother may apparently be free from any taint of the disease. It has been a subject of much dispute whether these are instances of latent syphilis or whether the women are really healthy. Whatever the cause, these cases show immunity in contracting syphilis. In 1837, Colles wrote that " a new-born child affected with inherited syphi- lis, even although it may have symptoms in the mouth, never causes ulceration of the breast which it sucks if it be the mother who suckles it, although con- tinuing capable of infecting a strange nurse." The substantial truth of this dictum has not been seriously questioned during the many years that have elapsed since its enunciation, although varying explanati(ms have been offered. Fournier states that the inoculation experiments of Caspari and Neumann have proved conclusively that the apparent immunity of the mother, Avho has borne a child syphilitic by its father, against the contraction of the disease from her offspring, is due to the fact that she has already been infected by syphilis dur- ing the intra-uterine period of the child's life. Thus, conceptional syphilis is to be classed with the hereditary form of the disease, since there is here no pri- mary lesion. This form of conceptional syphilis may remain latent for years. Diday advances as an explanation of Colles' law the idea that all infectious dis- eases may certainly be mitigated to the point of absolute protection by the methodically repeated inoculation of their essential cause (microbic) or of its products (toxic ptomaines, etc.). Bouchard considers that while the foetus retains the supposed pathogenic agent itself, the products dissolved in the blood find their way to the tissues of the mother and set up a nutritive change, ' Dr. F. R. Sturgis strongly denies the paternal transmission of syphilis. HEREDITARY SYPHILIS. 129 resulting in what he calls a "bactericidal condition." which renders difficult or impossible the development of the infectious agent when introduced by later inoculation, as from the lips of her child. The doctrine of syphilis being con- tracted by conception, sometimes called "choc en retour," although having wide acceptance, is not acknowledged by all. Kassowitz believes that the women who appear healthy and remain so, even after giving birth to syphilitic children, are really free from specific taint. Syphilis of the Placenta. — Dr. Frankel in 1873 published a paper in which he affirmed the existence of three forms of involvement of the placenta bv syphilis — /. e.^ endometritis decidualis, endometritis placentaris, and disease of the villous portion of the foetal placenta. This conclusion was based upon • an examination of over one hundred placentae. Zilles in 1885 published the results of a study of three hundred placentae derived from Prof. Saxinger's obstetrical clinic. He finds that placental syphilis can often be diagnosed microscopically, and that it oftenest happens in connection with foetal syphilis. The maternal portion of the placenta or the foetal part only may be affected, while, again, the whole of the placenta may be involved in the disease. Syphi- lis is one of the recognized causes of hydramnios. Morbid Anatomy. — The lesions of syphilis, while always essentially the same, will nevertheless be modified by age. Young protoplasm is active, and usually exhibits a marked reaction to ii'ritative processes, so that the tissues are apt to be extensively involved in hereditary syphilis. The lesions may be broadly divided into those involving the skin and mucous membranes, the vis- cera, and the bones. Skix axd Mucous Membranes. — The skin may be affected by erythema, maculo-papules, or papules. A vesicular and pustular eruption may occasion- ally be seen. Blebs or bullae often appear at birth in a severe type of the disease. Crops of boils, with well-defined, coppery-red bases, are apt to be symmetrically arranged when many are present, or asymmetrically distributed if only a few are seen. The distribution and course of the various eruptions will be noted more at length under Symptoms. In general, they develop quickly and spread over extensive areas of surface on account of the character of infant protoplasm, noted above, as well as from the activity of the circula- tion in the skin. The lesions of the mucous membranes may be in the form of catarrhal pro- cesses, of mueous patches, or of superficial or deep ulcerations. Any or all of these lesions may involve any part of the alimentary tract or of the respiratory tract. They are seen most commonly, however, in the upper part of these areas, in some part of the mouth or fauces in the former case, and in the nose and larynx in the latter. Still, they may likewise occasionally involve the intestine or trachea and bronchial tubes. Visceral Lesions. — The viscera are apt to be more extensively involved in hereditary than in acquired syphilis, the lesion being in the form of an inter- stitial hyperplasia more or less diffuse. Circumscribed gummy infiltrations are not so frequent. The growth of interstitial connective tissue, which grad- ually contracts, thereby partially obliterating the parenchyma of the organ, may involve the lungs, spleen, liver, pancreas, and testicle. Lungs. — Usually a portion of a lobe, but occasionally a whole lobe, may present a diffuse fibroid infiltration. The part involved is grayish-white in color and tough in consistency, and smTounded by an inflamed pleura. Under the microscope there is seen to be thickening of the septa and compression of the alveoli by fibrous tissue, which is quite vascular. Occasionally a few rounded masses about the size of a hickory-nut may be noted. These gum- 9 130 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. mata may break down in the centre into purifonn matter, but they arc not apt to exist in the same subject that the diftuse interstitial inflammation attacks. iSpleen. — The spleen is generally more or less enlarged from a diffuse inter- stitial hyperplasia. There usually coexists a thickening of the capsule. Accoi'd- ing to Dr. Gee, the severer the grade of syphilis the greater will be the hyper- trophy of the spleen. This enlargement may remain persistent for a long time after other symptoms have disappeared. Liver. — The liver, which is not infrequently affected, is hardened and enlarged from a diffused sclerosis. Occasionally the affection may be circum- scribed. The hepatic cells are compressed and the capillary blood-vessels partly obliterated by the pressure. As in cirrhosis in the adult, section of the liver is accompanied by creaking, and the cut surface presents a yellowish area, interwoven with whitish opaque streaks of fibro-plastic matter. The capsule of Glisson may be thickened upon the surface of the liver, and there may be local peritonitis. Gummata, in the form of small, circumscribed nodules, may be found in the tissue of the liver. They may be seen in association with cir- rhosis. These nodules are yellowish, with a tendency to soften in the centre. Pancreas. — Birch-Hirschfeld has called attention to the fact that there may be hyperplasia of the connective tissue of the pancreas, which on section pre- sents the same fibroid appearance seen in the liver and other visceral organs thus affected. He found in a few cases the head of the organ more involved than the remaining part of the gland. Testicles. — An interstitial orchitis may affect one or both testicles, produ- cing hardening and slight enlargement of the glands. The hyperplasia may be uniformly distributed through the organ, or the latter may be irregularly involved. The epididymis is not usually affected. Atrophy of the seminal ducts may ensue. Sufficient change in the testicle to be detected clinically is not often seen in hereditary syphilis. Kidneys. — Parrot has found small tumors, produced by infiltrations of round cells into the connective-tissue stroma, Avhich compress the tubules, and thus cause a colloid degeneration of the contained epithelium. If this process is extensive, -it will eventuate in a general atrophy of the kidney. General nephritis may be seen in hereditary syphilis, but it is difficult to say whether the latter is more than a predisposing cause of the former condition. Heart. — Gummata may be found in the heart. Dr. Coupland has reported a case where the walls of this organ were thickened and hardened. Bone Lesions. — Waldemeyer, Kbbner, Parrot, and R. W. Taylor have shown that various bony lesions are quite common in hereditary syphilis. Many of these lesions, that were formerly referred to rickets or scrofula, are now recognized as syphilitic. There are two principal ways in which the spe- cific poison affects the bones in early life. In one instance the brunt of the disease and morbid change takes place at the junction of the shaft with the epiphysis ; in the other, the periosteum covering the long bones is principally affected. Both of these varieties involve principally the long bones. Osteo-chondritis. — This inflammatory process is induced only by syphilis, and may be the sole manifestation of the taint. The lesion starts in the car- tilage joining the epiphysis with the diaphysis, where normal growth in length of the bones takes place ; hence deformity of the bone, due to a crippling of its proper development, may ensue. The lesion most commonly affects the bones of the forearm, leg, arm, and thigh, although other bones may be involved, such as the metacarpal and metatarsal bones, the clavicle, sternum, and ribs. The number of the bones affected appears to depend, to a certain extent, HEREDITARY SYPHILIS. 131 upon the severity of the general poisoning. It has been found in stillborn infants that most of the long bones may be thus affected, and in those born living, if the bone lesion is multiple, recovery is uncommon. The cartilage affected first becomes thickened and soft from proliferation of cartilage-cells, and there is at the same time lessening of the intercellular substance. This may be felt as a sort of collar-like swelling at the end of the bone affected. The swelling may be visible if the child is not too fat. If, as occasionally happens, one portion or side of the cartilage only is involved, the swelling will be felt not to completely encircle the bone, but as a circumscribed nodule. The disease is apt to be symmetrical and involve the distal oftener than the proximal ends of the bones. There is little change in the integument or sur- rounding tis&ues in many cases, as the disease is not apt to extend farther than the bone. In such a case the swelling may remain for a long time, accom- panied by little pain or disability. It may originally develop slowly or quickly, and its disappearance will usually promptly follow a proper mercurial treatment. In some cases, however, degenerative changes may ensue, with a breaking down of some part of the swelling. If the morbid process continues, there will be softening, soon followed by ulceration of the skin. If suppuration keeps up, the cartilage will be destroyed and the epiphysis completely sepa- rated from the diaphysis. Even in these cases the joint is not apt to be involved, although cases of subacute synovitis, and even pus in the joint, have been reported. If the ulceration is extensive, the epiphysis, when completely separated, may be extruded. When there is destruction of the cartilage and epiphysis, there will of course ensue arrest of growth and consequent deformity in the limb. Parrot has described cases in which the skin remains unbroken after separation of the epiphysis, inducing a condition of paralysis in the affected part. Dr. Taylor describes cases in which, the intervening cartilage having been destroyed, the epiphysis is united to the shaft only by fibres of periosteum. This membrane may become much thickened, and form a more or less complete cylinder, uniting the two fragments Avith considerable firm- ness. Bony spiculse shoot from its inner surface between the two osseous sur- faces, and thus eventually bony union is secured. The SAVollen periosteum may gradually resume a more nearly normal thickness. Osteo-chondritis develops eaidy in life, usually within the first month. The lesion may, however, occur later, when it is not apt to become multiple, and may be unsymmetrical in distribution. The question as to whether certain epiphyseal swellings may be due to syphilis or rickets will possibly arise. Other lesions of these two diseases will have to be sought after in order to aid in making a correct diagnosis. Such swellings are pretty surely syphilitic if they occur during the first six months of life, and at all times are relieved by mercurial treatment. Again, the epiphyseal swellings of rickets are always symmetrical, while those of syphilis may be unilateral. Periostitis. — This form of lesion occurs later in hereditary syphilis, usually after the child has begun to walk. It attacks by preference the femur, tibia, and bones of the forearm, occurring usually from the second to the foui'th or fifth year. There is more or less enlargement of the affected bone. At an early stage of the disease the bones are attacked symmetrically, but later cir- cumscribed nodes may be placed unilaterally. Dactylitis. — The phalanges and the metacarpal and metatarsal bones may be enlarged to several times their natural size. After an interval of time the skin may become inflamed and break down from the formation of an abscess. The proximal phalanges are more apt to be attacked than the distal, and sev- eral bones of each hand may be affected. There is not much destruction of 132 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. bone, even in severe cases, and, although the disease tends to run a slow course, it is always influenced favorably by treatment. Dactylitis is apt to occur in very young subjects, Avhen it takes the form of a gummatous infiltration. (Fig. 1). Fig. 1. ^ Syphilitic Dactylitis. Craniotabes. — The local thinning of portions of the cranial bones was formerly attributed exclusively to rickets, but is now known to ensue as well in the malnutrition accompanying sy))hilis. As it is due to pressure of the thin skull between the l>rain and pillow, it is especially apt to involve the occipital bone. Carpenter considers that both craniotabes and Parrot's nodes are often syphilitic manifestations, although they are more frequently regarded as evidences of rickets: 74 per cent, of cases of craniotabes are syphilitic, according to this author. Symptoms. — The symptoms of hereditary syphilis vary widely according to the extent of the poison. When the virus is concentrated, as in cases where both parents are syphilitic, the fcetus Avill be attacked by the disease in the uterus, and, as a result, we shall have abortion more or less early in the preg- nancy. As the disease abates in one or both parents the pregnancies will be longer in duration, until finally apparently healthy infants may be born. In some cases the infimt will present marked evidences of syphilis at birth ; often, hoAvever, the onset is delayed until later, and at birth there may be absolutely no manifestation of the disease. In 158 cases analyzed by Diday the first manifestation of symptoms occurred in 86 cases before the completion of one month ; in -to before the completion of two months ; and in 15 before the completion of three months after birth. The remaining 12 cases showed the symptoms in intervals varying from four months to two years. The earlier the disease manifests itself after birth, the graver will be the nature of the attack. Very early syphilis is usually accompanied by emacia- HEREDITARY SYPHILIS. 133 tion, eruptions of bulliie, particularly upon the palms of the hands and soles of the feet, and an extreme degree of corvza, cracked and ulcerated lips, and evi- dences of visceral and bony disease. In the older cases there may be no interference with nutrition, and possibly one or two mucous patches may be the only active manifestation of the disease. In studying the symptoms it may be well to consider the disease as it shows itself in different structures and areas of the body. Skin. — One of the early symptoms appearing upon the skin will be the eruption of small round pink spots, disappearing on pressure, and usually appearing first on the lower portion of the abdomen. It may spread from this location and finally involve the whole body. Pigmentation of these spots may ensue, and they may present a dark-red, coppery discoloration. This latter change may be considered as having a diagnostic value. In hereditary syph- ilis the rashes often develop rapidly, and are apt to be less symmetrical than those seen in adults. They are likewise polymorphous, as several different forms of syphilide may be exhibited at the same time in a given case. A pap- ular syphilide may be seen in the form of small or large flat papules, symmetri- cally distributed over the surface. These papules are not so apt to group them- selves into lines and circles as in older subjects with syphilis. They are not so solid and deeply infiltrated as in the adult. Upon the palms and soles these papules may be very abundant and fuse together, presenting a thickened, dull- red surf^xce. The vesicular syphilide is not common, and when seen is apt to be in very severe cases. The vesicles may be associated with pustules, and appear in closely-arranged groups about the mouth or chin or various other parts of the body, especially the nates and hypogastrium. Pustules may form, especially on the face, buttocks, and thighs. The ulceration is deeper and the crusts darker in color than in impetiginous eczema. Pemphigus likewise appears in the severe forms of the disease. It most frequently attacks the palms of the hands and soles of the feet ; it may have a copper-colored areola and develop rapidly. Crops of indolent boils, symmetrically distributed and of a copper-red color, may appear in connection with other eruptions. They are more apt to be seen in badly-nourished infants. In some cases the only appear- ance of syphilis upon the skin will be a smoky discoloration, seen most dis- tinctly in the prominent parts of the face, such as the eyebrows, cheek-bones, and bridge of the nose. The nutrition of the skin is much affected in cases Avhere the cachexia is marked ; it hangs in dry, loose folds, having an unhealthy, earthy appearance. Mucous 3Iembranes. — The mucous membranes, as well as the skin, present the earliest manifestations of the disease. One of the most typical lesions is the corvza, which may be the first symptom noted. First, there may be a serous discharge which attracts little notice ; this, however, gradually becomes worse, and the nasal secretion takes on a purulent or even a bloody character, and may be sufficiently irritating to cause excoriations of the upper lip. The mucous membrane itself becomes thickened, and the inspissated secretion soon dries, forming crusts, which may completely block up the passage through the nostrils and seriously interfere with nursing. The secretion may likewise be offensive. In severe cases, particularly where cleanliness is not practised and the decomposing secretions are allowed to remain in the nostril, there may fol- low ulceration of the mucous membrane, and possibly even necrosis of the adjacent bony parts. There is apt to be a flattening of the bridge of the nose, probably, to a certain extent, due to the interference with normal respi- ration. The inflammation may spread to the pharynx and larynx, although its action is likelv to be limited to the Schneiderian membrane. 134 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Mucous patches will be seen in most cases of hereditary syphilis, and, although they appear most constantly on the mucous membranes, they may be present upon the skin, particularly at its junction with the mucous membranes, or upon those parts which are thin and exposed to various secretions. They may occasionally be seen on any part of the cutaneous surface of the body. They are oftenest seen in the mouth, about the nose, upon the scrotum, vulva, labial commissures, and occasionally at the umbil- icus. In the mouth the most frequent situations are upon the angles of the lips, inside of the cheeks, the pillars of the fauces, the tonsils, and the sides and dorsum of the tongue. They consist, in the early stage, of a slightly raised segment of mucous membrane, presenting a whitish surface and red margins. This may soon ulcerate. When the mucous patches appear at the angles of the mouth, deep fissures will often form at the corners of the lips, extending sometimes well out into the cheek. These fissures are sometimes called rhagades, and are diagnostic. The secretions on these mucous patches are very infective. When mucous patches appear on the cutaneous surface, they are slightly raised, with a macerated appearance, and frequently seamed with erosions or cracks. In the late stages of hereditary syphilis mucous patches are not so numerous as in the earlier stages of the disease, but they frequently recur after the child is apparently restored to health. .Disturbance of Nutrition. — The extent to which the general nutrition of the infant is disturbed will depend upon the severity of the attack. In grave cases there is atrophy of all the structures of the body, the infant presenting a weazen appearance, with a countenance resembling that of an old man. These cases are almost invariably fatal, and are caused by the blighting influence of the virus. In many cases, however, a failure of nutrition will ensue gradually, consecutive to gastro-intestinal disturbance. This may be due to actual specific disease of the liver, stomach, or intestines, or it may be due to indigestion and malassimilation only indirectly caused by feebleness from the cachexia. In bottle-fed babies digestive disturbances ai'e marked and severe, infants upon the breast being much less liable to suffer. In some cases the infant will present very slight disturbance of the general nutrition, being plump and well-nourished throughout the course of the disease, which may be only manifested by mucous patches or mild evidences of the infection. Condition of the Blood. — A condition of profound anaemia is frequently seen, particularly in severe cases. Johann Loos states that hereditary syphilis is always associated with an an?emia which under some conditions may reach an extreme degree of intensity. This anaemia is characterized by a diminution in the number of the red blood-corpuscles, by quite a marked alteration in these corpuscles, the appearance of megalocj'tes and microcytes, and by the appear- ance of nucleated erythrocytes, sometimes in quite notable quantity. It is always characterized by the constant existence of leucocytosis, Avhich may often become extreme, and by the appearance of myelo-plaques in the blood. This ansemia is a very important and significant symptom of the disease, and may directly occasion a fatal issue. He further states that there are only two diseases common to childhood in which the lesions of the blood suggest the changes just described, and these are splenic anaemia and severe forms of rachitis. A form of syphilis h?emorrhagica neonatorum has been described by Bumstead and Taylor. There may be simply a limited subcutaneous effusion, or the mucous membranes may be the seat of the haemorrhage. Haemorrhage at the umbilicus shortly after birth may be due to this cause. Crlandular Enlargements. — General adenopathy is not seen in the hereditary HEREDITARY SYPHILIS. 135 form of syphilis. There may be enlargement of the chains of cervical glands consecutive to lesions in the adjacent mucous membranes, and occasionally there may be an affection of the inguinal, axillary, or cervico-maxillary glands without any deeper lesions being noted to account for their existence by septic absorption. The glands are hard, moving without pain in the areolar tissue under pressure by the finger. Some writers consider that enlargement of the epitrochlear glands is pathognomonic of congenital syphilis, but well- marked cases occasionally fail to show this sign upon careful examination. Bony Organs. — The frequency with which the bones are involved in hereditary syphilis has been noted in the morbid anatomy of the disease. In every case the long bones should be carefully examined for enlargement and thickening at the epiphyseal and distal ends. In cases where suppuration has taken place the epiphysis may be separated from the shaft, and crepitation will then be found upon careful handling. The joint itself may occasionally be involved in the inflammation, showing the well-known symptoms of arthritis. Where the bones are much affected there will be some disability of the limb, possibly extending to complete paralysis. Immobility in such a case is with- out doubt due to the affection of the bones. Dactylitis. — In the early period of the disease an enlargement of the phalanges is frequently seen, and occasionally also of the metatarsal and metacarpal bones. The proximal phalanx is more frequently attacked than the distal ; the affection may spread to all of the phalanges, but is more apt to involve only one, which may be enlarged to double its normal size. This enlargement is the result of specific inflammation of the bone and periosteum, and runs a slow course unless modified by specific treatment. There is not apt to be much involvement of the soft parts ; the integument will be reddish and inflamed, but there is little tendency to suppuration and ulceration. These swellings usually present a fusiform shape, with a hard, firm sensation to the touch. Teeth. — The appearance of the deciduous teeth is delayed in hereditary syphilis, as in rachitis. The first teeth may not appear until the tenth or twelfth month, or even later. These teeth are poorly developed and apt to undergo early decay. There is usually a similar delay in the appearance of the second teeth, which present more pathognomonic changes, which Avill be noted in connection with late hereditary syphilis. Nervous Disturbances. — Lesions of the nerve-centres do not often appear in hereditary syphilis ; there may be, however, an occasional palsy due to a peripheral cause. One form in connection with bony lesions has already been mentioned. There may be contractures and paresis, however, where no bony lesion can be noted. Henoch questions whether such affections may not be myopathic in their origin and independent of the nervous system. The following case coming under my observation illustrates a case of paralysis evidently caused by interstitial syphilitic myositis: An infant four weeks old, whose mother presented syphilitic lesions, was born healthy at full term. When seven days old it was noticed that the right leg Avas drawn up and apparently did not move ; also the right arm. There was complete loss of power in these members ; there was wrist-drop, and a loss of faradic and galvanic irritability in the extensors of the left wrist. The muscles affected were rather hard and painful to the touch. There was an enlargement at the epiphyseal end of the left humerus. The paralysis completely disappeared in about two months under specific treatment. Dr. Eustace Smith states that a form of real paralysis has been occasionally seen affecting the branches of the brachial plexus, causing more or less com- plete loss of power in the arm. 136 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Onychia. — Two kinds of onychia are noted in hereditary syphilis — the ulcerative and the nutritive. In the ulcerative form the pustule appears at the margin of the nail, which soon breaks down, leaving a sloughy surface, which may destroy the matrix. The surrounding skin presents a coppery discoloration. In the nutritive form, which is apt to appear later, the ulcer has a sloughy base, and presents a swelling around the periphery of the nail, which becomes thickened and brittle. • Swelling and deformity of the phalanx may ensue. In a case recently observed, a child of two years, whose father had a specific history, presented immense bulbous masses upon the extremities of the thumb and middle finger of the right hand and the thumb and fore finger of the left hand. These were granular, warty masses about the size of hickory-nuts, with the nail protruding backward. When the infant was eight months old it appeared healthy, except that the finger-nails now involved were like claws and were reddened as if scalded. The trouble had continued until the nutritive changes produced the enlarged mass here noted. There had been a history of "snuffles," abscesses on the buttocks, sore lips and gums, but at the time of the examination the only other manifestation of the disease was a large mucous patch in front of the scrotum. In the nutritive form of onychia the hyperaemia of the matrix and the deformity of the phalanx, if not extreme, may disappear under specific treatment. Iritis. — This is an exceedingly rare affection in hereditary syphilis, but cases have been reported by Mr. Hutchinson in infants varying in age from six weeks to sixteen months. It does not differ fiom the same manifestation in adults. Alopecia. — There may be loss of hair in the scalp, eyebrows, or eyelashes. The last form is the most pathognomonic, as there may be a deficiency in the nourishment of the hair of the scalp in rickets or any condition of cachexia in infants. General Irritabiliti/. — Syphilitic infants are very fretful, and the cry is of a peculiar high-pitched character. This fretfulness is particularly apt to be present at night, at which time the child is extremely wakeful. In this, how- ever, it does not differ much from rickets. Diagnosis. — A difficulty in the diagnosis of hereditary syphilis may obtain where typical lesions are not well marked, or where it is a question between syphilis and scrofulous or tubercular lesions. In cases of marasmus, if there is no history of chronic indigestion, particularly if the infant have been fed at the breast, there is strong suspicion of syphilis. A careful examination for mucous patches will often throw light on such a case. Chronic coryza is likewise a valuable sign in diagnosis. The following points of distinction between syphilitic and scrofulous lesions of the skin have been given by Dr. P. A. MorroAV : (1) Syphilitic lesions are general in their distribution ; they may occur upon any region of the body. Scrofulous lesions are more limited in their localization : they have a special predilection for the neck or regions rich in lymphatic glands. (2) Syphilitic lesions are ambulatory and changing ; they disappear and reappear elsewhere. Scrofulous lesions are fixed and permanent. (3) The color of syphilitic lesions is reddish-brown or "lean-ham" tint. The color of scrofulous lesions is brighter and more violaceous in hue. (4) Syphilis is distinct from scrofula in its objective appearances and mode of evolution. In the initial stage the syphilitic neoplasms are firm and hard ; the scrofulous infiltrations are softer and more compressible. In the ulcerative stage the differences are more pronounced ; the ulcers of syphilis are cleaner cut, regular in contour, with perpendicular, firmly-infiltrated borders encircled by a pigmented areola ; HEREDITARY SYPHILIS. 137 scrofulous ulcers are irregular, with soft, undermined borders ; tliey are painless, bleed easily, and show slight tendency to spread. (5) The crusts of syphilis are bulkier, thicker, with a tendency to accumulate in layers, and darker in color ; the cicatrices are smooth and remain long surrounded by a pigmented areola. The crusts of scrofula are softer, more adherent; the cicatrices are elevated, irregular, bridled ; they retain their violaceous color for a long time. (6) The course of a s^^philitic ulcer, though sluggish and chronic, is much more rapid than that of scrofula. (7) Absence of pain and local reaction characterize both syphilitic and scrofulous ulcers ; the}^ are essentially lesions without symptoms. In connection with the bony lesions it is important to diagnose between syphilis and tubercular and rachitic affections. The following points in diagnosis between syphilis and tuberculosis are given by Dr. Morrow : (1) Syphilis ex- hibits a marked predilection for the long bones ; its habitual localization is in the diaphysis, and almost always at its terminal extremity. Tuberculosis is almost exclusively situated in the epiphyses, rarely affecting the shaft. (2) In syphilis there is a marked enlargement of the bone by more or less volumin- ous osseous tumors or hyperostoses, with little or no involvement of the soft parts ; and in tuberculosis the tumefaction is due less to increase in the size of the bone than to oedematous infiltration of the soft structures. (3) In syphilis there is little tendency to suppuration and necrosis ; in tuberculosis the pyogenic tendency is marked. (4) In syphilis osteocopic pains, with tendency to noc- turnal exacerbation, are a pronounced feature ; in tuberculosis the pain is dull and heavy, not aggravated at night ; sometimes there is entire absence of acute painful symptoms. (5) The osseous lesions of syphilis rarely react upon the general system, while those of tuberculosis often determine a marked impair- ment of the general health, grave complications, hectic fever, cachexia, etc. In syphilitic dactylitis there is little involvement of the soft parts, the swelling being caused by the enlargement in the size of the bone. In tuber- cular dactylitis the swelling is due more to an oedematous infiltrated condition of the soft tissues than to enlargement of the bone. In the latter cases breaking down of the tissues and ulceration are more apt to ensue. The diagnosis beiween syphilis and rickety bone-lesions may be of great importance. Epiphyseal swellings occurring under six months are very apt to be syphilitic. In syphilis the epiphyseal swelling may be unilateral, but it is always symmetrical in rachitis. In doubtful cases the swelling must be sub- jected to specific treatment. It is well to remember, however, that rickets and syphilis may coexist in the same case. There is almost invariably enlargement at the costo-chondral articulations in all cases of rickets, which is absent in syphilis. Prognosis. — -According to Kassowitz, one-third of all syphilitic children die before their birth, and among those who are born 34 per cent, die in the first six months of life. Fournier places the mortality, when derived from the father alone, at 28 per cent. ; from the mother alone, 60 per cent. ; when from both parents, 68J- per cent. The earlier the symptoms appear after birth, the severer will be the type of the disease and the worse the prognosis. Involve- ment of the bones and viscera means a severe type of the disease. Infants fed upon the breast will have a much better chance than those artificially fed. In bottle-fed infants, particularly when the disease appears early, the prognosis is almost always fatal ; it is invariably so in hospitals and lying-in institutions. Any interference with digestion and assimilation, no matter from what cause, will necessitate a guarded prognosis. If the coryza is extreme and breathing much disturbed, the pi'ognosis must be altered in proportion to the amount of 138 AMERICAX TEXT-BOOK OF DISEASES OF CHILDREN. such disturbance, -which interferes with rest and the taking of food. If the digestion remains good, and particularly when the manifestations of the disease are not severe, complete recovery takes place, and the infant may grow up healthy and strong. Late Hereditary Syphilis. In some cases of hereditary syphilis the manifestations of the disease during infanc}' may be exceedingly mild, and, in fact, overlooked. It is possible in such a case that the poison may show itself in various ways during the period of childhood. " St/pJnlis tarda " is a term applied to those cases in which the first manifestations of hereditary syphilis appear in childhood. The existence of such a condition without any earlier evidence of the disease has been dis- puted. It is analogous to the discussion as to whether syphilis in the adult may present late secondary or tertiary symptoms without being preceded by earlier lesions. Late hereditary syphilis may manifest itself either in certain active lesions plainly to be attributed to this condition, or by certain developmental defects that may easily be confused with scrofula, tuberculosis, or rickets. It may be well for us to note some of the more characteristic lesions. Bone Affections.- — One of the commonest manifestations is a periostitis involving various long bones, especially the tibia, the ulna, the radius, and the humerus. Accompanying this periostitis there may be considerable thick- ening upon the surface of the bone, sufficient to induce a change in its form. The lesion may be multiple and symmetrical, although occasionally unilateral. It is attended often with little discomfort aside from occasional nocturnal pains. The nasal bones may be affected, producing much deformity by destruc- tion of the bony arch of the nose. In many cases not so severe there is marked flattening of the bridge of the nose and a wide separation of the eyes. The frontal bone is apt to be large and flat, with prominences somewhat exagger- ated. There is also usually a very high palate arch. Dactylitis may be seen in this late stage of the disease, and sluggish swellings of the meta- carpal and metatarsal bones. The secondary teeth are afi'ected in a Avay that has been considered pathognomonic. As is well known, Mr. Jonathan Hutchinson first called attention to this condition. The principal change is noted in the two superior middle incisors, which are small, peg-shaped, and placed at such an angle that the cutting borders, if continued, would meet. They may occasionally be deflected outward, as in the accompanying illustration. (Plate V.) The cause of this maldevelopment has been explained by Four- nier as due to defective growth within the alveolus, while Hutchinson refers it rather to an early stomatitis or an alveolar periostitis often present during infancy. The incisors are apt to be notched at the lower edge, as is well shown in the plate, which is taken from a case under the care of Dr. Stowell. The enamel is usually eaten aAvay in this portion of the teeth. Dr. John N. Mackenzie has called attention to ulceration of the palate, which is apt to take place in the centre, and be followed by caries or necrosis of the bone. There may be simultaneous or consecutive deep ulceration of the palate, pharynx, and naso-pharynx at any time previous to the age of puberty. Large and indolent mucous patches may be present upon the cheek, tongue, gums, and especially about the corners of the mouth. The ulceration about the lips may leave long scars, particularly to be seen at the commissures of the lips. This is most beautifully shown in the accompanying illustration of Dr. Sto- well's case. (Plate V.) HEREDITARY SYPHILIS. 139 Kidneys. — Fournier considers that chronic degenerative changes may take place in the kidneys, usually in the form of a parenchymatous nephritis and amyloid degeneration. Interstitial Keratitis. — There is frequently noticed an opacitj' of the cornea without much congestion of the conjunctiva. The opaque areas may, in severe cases, coalesce, and cover the whole cornea. Although primarily attacking one eye, it soon involves the other. There may coexist an iritis, presenting symptoms which are indolent in character without the severe pain and photo- phobia so often seen in many cases of iritis. It may be difficult to recognize the existence of iritis when the cornea is opaque from the presence of abun- dant interstitial keratitis. Deeper-seated troubles, such as choroiditis and reti- nitis, may occasionally occur. The G-enitalia. — Occasionally a painless enlargement of one or both testi- cles may be noticed, accompanied by a slight degree of hydrocele. This con- dition may sometimes involve the epididymis and the cord. When the testicle is thus involved, there are apt to be syphilitic lesions in other parts of the body, which will aid in diagnosis. In many cases all the evidence of syphilitic taint, in childhood will be seen in arrested and perverted development. Such a child exhibits in its growth much retardation of development in comparison with other children of the same age. This may be particularly" seen in the genital organs, the testicles at puberty being the size seen in very early child- hood, and in girls an absence of mammary development, delayed menstruation, and a non-appearance of hairs on the genital and axillary regions. Fournier has given the name •* infantilism '" to this defective physical and mental devel- opment. Such cases not infrequently develop epilepsy. The Treatment of Syphilis. The dictum of Dr. Holmes that the proper treatment of some diseases should be begun one hundred years before birth may be modified, in syphilis, to a treatment existing several months before birth. There is no doubt that pai'ents who exhibit any specific symptoms or who have had syphilitic children should be subjected to constant specific treatment and oversight. Such treat- ment may avoid miscarriage, and possibly prevent the development of syphilitic disease in the infant. The treatment of the syphilitic infant resolves itself into specific medication directed to the actual poison of the disease and to means aimed to prevent the collateral loss of nutrition which is so common and so grave in these cases. Mercurial treatment may be applied by external or internal medication. The former is particularly adapted to cases where infan- tile diarrhoea and indigestion may, to a certain extent, contraindicate the inter- nal use of mercury. Daily inunctions of mercurial ointment mixed with from four to eight times its quantity of vaseline or rose ointment are efficacious. It may be rubbed on the inside of the thighs or in the axillae, using a portion about the size of a small hickory-nut. Or the ointment may be applied on a flannel roller and bandaged about the child once a day. Before applying the ointment in this way the skin must be cleansed thoroughly with soap and tepid water. A little more cleanly method of local medication consists in applying five drops of a 10 per cent, solution of the oleate of mercury three times daily. It is certain that under external applications the specific lesions will frequently disappear. It is probable, however, that it will be found, as a rule, more satisfactory to employ internal medication. Mercury with chalk is one of the best prepara- tions, in doses of one-fourth of a grain to one or two grains twice a day. Dr. 140 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Jacobi prefers calomel, on account of the rapidity of its action, in doses of from -^ to \ grain three times a day. Bichloride of mercury has man}'^ adherents. The li(iuor of Van Swieten is the form recommended by Parrot for internal administration. The formula is as follows : ^. Bichloride of mercury 1 part. Water 950 parts. Rectified spirits 100 parts. Sig. 5 to 20 drops in milk three times a day. The bichloride of mercury may be given in simple watery solution, which may be combined with milk, and hence readily taken by the infant. Tbe dose varies from -^-g-g- to gig- of a grain, according to the age and condition of the infant. If intestinal irritation be caused by the drug, a mixture of wine of pepsin and elixir of bismuth may be used as a menstruum. An important element in the management of these cases will be the local treatment, applied to mucous patches, excoriations, and especially to the coryza. Ulcerations and destructive processes in the nose may be largely avoided by keeping the nasal . passages clean by tepid Avater or bland oil. A 2 per cent, solution of the oleate of mercury will be efficacious in the nose. Mucous patches or condylomata should be kept clean, and may be dusted with calomel and bismuth. Nitrate of silver may be applied to patches appearing in the mouth that are intractable to internal treatment. Where the bones are involved and evidence of gumma in any portion of the body is present, iodide of potash should be employed. In the visceral lesions this remedy likewise acts well; and if the indications arise, mixed treatment, by combining the biniodide of mercury with iodide of potassium, may be em- ployed. The iodide of potassium is most efficacious, although the iodide of sodium may be administered with good results. The dose should be moderate, not averajjins more than a few grains. The general care of the nutrition of the syphilitic infant is most important. The chances for maintaining good nutrition are much improved by keeping the baby on its mother's breast. If the mother is unable to entirely supply the infant with nourishment, the bottle may be employed, but never to the com- plete exclusion of the breast. The well-known fact that an infant cannot infect the mother, although the latter shows no evidences of syphilis, justifies us in insisting upon her nursing her own infant. The employment of a healthy wet- nurse, although of advantage to the infant, is not justifiable, as the former will almost surely be infected by the latter. After nursing, the nipple should always be carefully cleansed, as well as the infant's mouth, by the use of some bland disinfectant solution. In cases in which the infant is deprived of the breast the most scrupulous care and cleanliness must be exercised in artificial feeding. A mild form of indigestion will severely handicap the syphilitic infimt, and may eventuate in its death. General tonic treatment and stimulation may be employed in connection with specific treatment. The treatment of the later forms of syphilis will depend upon the activity of the morbid process. Mercury should always be exhibited in some form when there is any evidence of active syphilitic disease. It has been proven that small and proper doses of mercury are tonic in syphilis, and actually relieve the hydmemia and defective nutrition so often seen in this disease. If there is no evidence of an active syphilitic process, the treatment will resolve itself into improving the nutrition of the child in every way. Good food, tonics, iron, cod-liver oil, change of air when possible, are all of value in aiding healthy growth and development in these retarded cases. PART III. THE ACUTE INFECTIOUS DISEASES. MEASLES. By LOUIS STARR, M. D., Philadelphia. Rubeola is an acute, infectious disease, characterized by coryza and other catarrhal symptoms, by continued fever, and by an eruption of slightly elevated, crimson papules upon the face and body, followed by furfuraceous desquamation. It is perhaps the commonest of the infectious diseases of childhood, and very few individuals arrive at adult age without having suffered from an attack. One attack usually protects against a second, though instances in which there have been two, or even three, attacks are not rare. In large cities scattered cases of measles may be encountered at almost any time, but at certain recurring intervals, varying from eighteen months to two years, the disorder becomes epidemic. These epidemics are alike in the fact that young children, being unprotected by a previous attack, uniformly suifer most ; unlike, in the extent of their prevalence, in fatality, and in the accentuation of particular symptoms. In isolated localities, having infrequent communication with large centres of population, and where measles has pre- vailed only at long intervals, the disease when it does arise finds a greater num- ber of victims, attacks a larger proportion of adults, and is more fatal. "When introduced to a virgin soil the virulence is extreme. As an instance of this the four months' epidemic of 1875 in the Fiji Islands may be cited: during it 40,000 natives died out of a population of 150,000 — upward of 1 to every 4 souls. By contrast, the mortality in London in 1886 — an average year — was 1 to each 2000 of the population. Etiology. — The prime cause of the disease is a specific poison, the nature of which has not been determined, though A. Ransome and Braidworth and Vacher have discovered, in the breath and secretions of measles patients, certain peculiar organisms identical with those to be described as existing in the skin, the lungs, and the liver. It is certain, however, that the poison spreads by contagion, and most probable that, w^hether or no these micro-organ- isms carry it, it is given off in the breath and secretions. The contagion is usually conveyed directly from the sick to the well, and is so virulent that when once introduced to a dwelling or hospital ward its spread is rarely stopped until all unprotected inmates suffer. It may be carried from place to place by fomites, but simple airing of the clothing is usually sufficient to dis- infect it. When such instances of infection occur close connection is shown, the medium being a child or nurse coming directly from an infected house. Experimentally, the disease has been propagated by inoculation wdth the blood, the nasal and bronchial mucus, and the tears of a patient, and also 141 142 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. with the serum taken from the vesicles which occasionally accompany the eruption. Infection begins in the incubative stage, is most active during the pre-eruptive period of coryza and fever, continues throughout the eruption, and thereafter rapidly subsides, to disappear at the end of the third week. No age of infancy or childhood is exempt from measles. It may occur in sucklings a few weeks old, but is uncommon during the first six months of life. The period of greatest susceptibility is between the second and sixth years. According to some authorities, males are more prone to be attacked than females, but the disproportion between the two sexes is insignificant. Season, too, seems to have little influence in furthering the onset of the disease. If there be any difference, it is in favor of the damp, changeable, depressing weather of March, April, and early May. In the Children's Hospital of Philadelphia, for example, scarcely a year passes in which there is not a more or less extended epidemic during these months. Apart from unknown atmo- spheric causes, the explanation may be found in the fact that at this season children are below par, or impaired in health by the disorders and confine- ment incident to the winter months, and therefore less able to resist the contagion which is always latent in large cities. Pathology. — When death comes early in the course of the disease from the force of the poison itself, an autopsy reveals hypostatic congestion of the lungs, hypememia of the mucous membranes, and congestion of the organs generally, with extravasation into their substance, and softening. The blood is fluid, dark-colored, and deficient in fibrin. During an epidemic at the Philadelphia Hospital, Drs. Keating and Forraad detected large numbers of microbes in the liquor sanguinis and white corpuscles of blood taken from malignant cases, and the author has since made the same observation. Quite recently, too, a bacillus has been discovered in the urine of rubeolous patients. What relation these organisms bear to the disease cannot yet be definitely asserted. In sections of skin made on the sixth day of the eruption Braidworth and Vacher found SAvelling of the choriura and thickening of the rete Malpighii, due to great proliferation of cells which extended along the hair and sweat-ducts into the glands. Spark- ling, colorless, spheroidal, and elongated bodies were also present in the true skin next to the rete, in the lungs, and in the liver. In each situation thes,e bodies were mixed with others, spindle-shaped, staff-shaped, and canoe-shaped ; all appeared to be albuminoid in character. Other morbid appearances vary with the complications upon which death so frequently depends. The most common lesions are those of diff"use broncho- pneumonia and of structural alterations of the mucous membrane of the gastro- intestinal tract, either catarrhal inflammation, follicular entero-colitis, ulcerative inflammation, especially of the colon, or softening. Less frequent are caseation of the bronchial glands, miliary tuberculosis of the lungs, pulmonary collapse, membranous laryngitis, diphtheria of the pharynx, and effusions into the pleurae and other serous cavities. Incubation. — The interval between the actual introduction of the poison and the appearance of the first symptoms of illness has been quite accu- rately determined — first, by experiuient, measles having been introduced by inoculation in Edinburgh, Italy, and Germany ; second, by the careful study of outbreaks in virgin soil, such as that in the Faroe Islands, by Panum ; and third, by ordinary clinical observation. From all these sources the period may be fixed at from ten to twelve days. Adults and older children may complain of distaste for food, slight head- MEASLES. 143 ache, and lassitude for several days before the actual beginning of the disease, but younger children appear to be perfectly well, and practically there are no symptoms during incubation. Symptoms. — The course of rubeola may be divided into several stages. Prodromal Stage. — This lasts about four days, and is characterized by the following group of symptoms : lassitude, irritability, at times chilliness, pain in the back and limbs, headache, loss of appetite, thirst and other indications of gastro-intestinal disturbance, and, more important, fever, with the- various signs of catarrhal irritation of the mucous membrane of the eyes, nose, fauces, and larynx. The chilliness is not marked, rarely amounting to more than a disposition on the part of the patient to keep near a fire or a desire for more clothing, and a degree of coolness in the extremities appreciable to the nurse's hand. The same may be said of pain in the back and limbs, its presence in older children being established only by close questioning, and in younger by their showing indications of suffering when moved. Pyrexia is uniformly present. It may be postponed until the second day of the prodromal stage, but usually begins on the first. The fever is contin- ued in type, the ascent of temperature being marked by evening exacerbations Fig. 1. 1 F 104° 103° 102° 101° 100° 99° 98° 97° Days ofDit. PvXte. Betp.

This chart was taken from a negro boy set. eight years, a patient at the Children's Hospital, Philadelphia, The attack of measles began on the day marked 1 ; the eruption was detected on that marked 5, and was at its height on 5 and 6. (about 2°) and morning remissions (about 1°), which shoAv a tendency to become less decided and shorter as the day of eruption is approached. Sometimes there is a marked remission or complete intermission on the second or third day, after which the temperature curve pursues the ordinary course. (See Figs. 1 and 2.) 144 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. With the rise in temperature the pulse becomes increased in frequency, force, and volume, though it is rarely as frequent as in scarlet fever. The skin, while moist, feels hot ; complaints are made of frontal headache ; and the child, at first irritable and restless, gradually passes into a condition of quiet and drowsiness, when it is said to "sleep for the measles." The pathognomonic catarrhal symptoms begin with, or even precede, the pyrexia. These are inflammation and redness of the conjunctivae — the pal- pebral portions especially — injection of the whites of the eyes, photophobia, lachrymation, stuffing of the nose, sneezing, and an abundant discharge of muco-purulent fluid from the anterior nares. The secretions from the eyes and nose are irritating and excoriate the skin over which they flow ; the red- ness thus produced, with the injection of the eyeballs, the swelling of the lids and face generally, make up a heavy, almost characteristic, physiognomy. Cough is usually present from the first day. Slight and infrequent in the beginning, it gradually increases, until on the third or fourth day it assumes a peculiar character. It is laryngeal, hard, dry, rather hoarse, and occurs in short paroxysms. Expectoration, when present, is slight and consists of clear, viscid mucus. The voice is hoarse. The tongue is covered with a light white coating ; the tonsils are moder- ately enlarged ; the mucous membrane of the soft palate, fauces, and pharynx is uniformly swollen and reddened, and from twelve to twenty-four hours before the close of the prodromal period often becomes maculated Avith darker red, slightly-elevated spots closely resembling those of the cutaneous eruption ; the latter appearance is most noticeable upon, and may be confined to, the soft palate. Moderate enlargement of the glands behind the angle of the jaw is an ordi- nary feature, and the same condition of the cervical lymphatics may sometimes be observed. There are anorexia, thirst, slight difficulty in deglutition, sometimes vomit- ing, and at first constipation, later diarrhoea. Of nervous manifestations, irritability and drowsiness have been already mentioned. The latter symptom is often very marked, the child sleeping for the greater part of one or even two days before the rash appears, waking only to ask for drink or to have its urgent wants attended to, and then droAvsing off again. There is no danger in this condition, unless it be associated with indications of cerebral disease or deepen into coma or alternate with decided delirium. Restlessness with mild delirium at night may take the place of drowsiness, and, in exceptional cases, convulsions occur. Eruptive Stage. — The eruption usually appears in the evening of the fourth day. For a few hours immediately preceding its outbreak the nervous symptoms are increased, or, if absent before, are developed, and it is at this time that convulsions are most liable to take place. The rash shows itself first on the skin immediately behind, beneath, and in front of the ears ; thence it spreads to the rest of the fiice, the neck, the trunk, and the limbs, completing its extension over the entire body in from twenty-four to forty-eight hours. It begins in the form of distinct maculae, more or less deep crimson in color, rounded in shape, Avith irregular edges, and varying from half a line to three lines in diameter. These soon develop into slightly elevated papules with hard, flat summits, Avhich feel firm to the touch and temporarily lose their color under pressure. Isolated and few in number in the beginning, the papules rapidly become more abundant, and show a tendency to arrange themselves into irreg- ular clusters, the unaffected portions of the skin preserving the normal appear- ance. The intensity of the eruption varies greatly ; sometimes the papules are MEASLES. 145 quite scattered and the few clusters are separated by large areas of healthy skin ; at others they are so numerous and coalesce so closely that extended portions of the surface assume a dark-red tint. This coalescing is most frequently observed on the face, on the neck and back, and near the flexures of the joints. Occasionally, in very severe cases, minute vesicles form on the summits of the papules. After full development the rash shows little change for one or two days. It then begins to fade in the order of its appearance, assuming a lighter or yellowish-red color, and in a day or two later disappears, leaving only faint reddish stains which mottle the skin for several davs longer. The subsidence of the rash is followed by desquamation, the epithelium falling in very fine bran-like scales. This process is most noticeable on the face, but even in this position may readily escape observation. The rash may vary in other characters as well as in its intensity. Some- times the papules on their first appearance are hard and prominent, resembling closely those of variola. Again, their crimson color may not entirely disap- pear on pressure — a condition due to great hypersemia of the skin. Finally, the eruption may steadily grow darker until a deep-purple color is acquired ; this is also due to intense hyperaemia with rupture of distended cutaneous capillaries. Such a rash does not disappear on pressure : it remains at its height much longer than the ordinary eruption, and is slow in fading. Fig. 2. F 105° 104° 103° 102° 101° 100° 99° 98° 97° Day»ofDU.

The fever does not abate on the appearance of the eruption ; on the con- trary, it often attains a higher marking (103°-105° F. in the axilla) on the first and second day ; after that, as the rash fades, it rapidly falls to the normal line. 10 146 AMEBICAX TEXT-BOOK OF DISEASES OF CHILDREX. The preceding chart (Fig. 2) presents a fair picture of the temperature curve of measles of average severity. The patient who furnished the record was a boy five years old, an inmate of the Children's Hospital. Philadelphia. Having been directly exposed to contagion, the symptoms of corj-za were noticed on the day marked 1 : the eruption appeared on the evening of that marked 4, and was at its height on 5 and 6. Afterward the eruption rapidly fsided, and with it the temperature fell almost to the normal line on 8, though complete lysis was delayed for forty-eight hours by a trifling secondary laryn- geal catarrh. The pulse increases in frequency as the temperature rises, and follows its curve moderately closely. The maximum ratio is usually about 120 beats per minute, though it occasionally rises higher, as in the case just referred to. During the acme of the eruption and pyrexia the catarrhal symptoms become more severe. The conjunctive^ are red, the eyelids are much swollen, photophobia is extreme, and there is a copious flow of irritating tears ; the nasal ])assages are dry and encrusted, or there is a free discharge of acrid mucus, and crusts of dried blood may often be seen about the nostrils, for epistaxis is common. The upper lip is tumid and excoriated, the cheeks are swollen and deeply reddened, and the characteristic physiognomy, already mentioned as existinor in the prodrotnal stage, is more strikincrlv marked. The tongue is usually moist, with a thick, yellowish-white central coating and red tip and edges ; the soft palate, tonsils, and pharynx are red ; and the throat feels sore. Thirst and anorexia continue ; there may be some tume- faction and tenderness of the abdomen ; moderate diarrhoea is the rule ; and in some cases there are violent vomiting and purging. The respiratory movements are somewhat quickened : the voice is husky, the cough is parox- ysmal, dry, hoarse, and troulilesome, and attacks of spasmodic croup are apt to occur. Physical examination of the chest reveals the signs of catarrh of the larger bronchial tubes, and as a rule — especially in scrofulous children — of enlargement of the bronchial glands. The probability of a similar enlarge- ment of the glands at the angles of the jaw and sides of the neck must also be remembered. The urine is scanty, dark yellow in color, with abundant urates, and, while the temperature remains elevated, may contain a trace of albumin. Prostration of the general strength is not decided in the majority of cases. Stage of Decline. — So soon as the rash begins to fade — fourth day of eruption, eighth of disease — the other symptoms rapidly abate. The pulse loses its rapidity, though it is somewhat weaker than normal ; the temperature steadily falls, often with considerable sweating ; the corvzal symptoms subside ; the voice becomes less hoarse ; the cough grows looser and less frequent ; and, if the child be old enough, nummular masses of muco-purulent matter are freely expectorated. The tongue cleans off; appetite returns; there is no longer thirst, irritability, or restlessness ; the bowels return to their normal condition, and ordinary health is soon regained. Modified Forms. — Measles without eruption and measles without catarrh have been described by different authorities. In regard to the first modification, it is diSicult to doubt the records of certain isolated cases that have occurred during epidemics of the disease, though the author has never met with any examples. On the other hand, cases reported as "rubeola sine catarrho" must be classed under rubella rather than modified rubeola. There is. however, a form of measles which is distinguished from its outset by typhoid symptoms, and is very fiital. Malignant, ataxic, or black measles, as this variety is called, may occur as an epidemic or sporadic affection, but it MEASLES. 147 is usually the former. There is great prostration ; the patient is dull and stupid ; the pulse is small, feeble, and frequent ; the respirator}^ movements are diffi- cult and rapid ; the rectal temperature is high, often reaching 107° or 108° F., while the hands and feet feel cold: the tongue is dry, broAvn, and thickly coated ; epistaxis is often obstinate, and hematuria may occur. The rash appears slowly, imperfectly, and irregularly, assumes a livid, purplish, or blackish hue, and may quickly retrocede ; . at the same time, the skin is thickly mottled with petechiie. The attack progressing, the pulse becomes so rapid that it can scarcely be counted; there is muscular tremor with mutterincr delirium, and life terminates in coma or convulsions. After death ecchymoses may be found in the viscera. Complications. — The conditions which disturb the regular course and threaten the ordinarily favorable result of measles are mainly furnished by an undue development of certain of the usual or unusual features — an exaggera- tion determined either by the nature of the special epidemic or by certain constitutional peculiarities of the individual affected. These complications may be described in the order of their frequency and importance. Bronchial catarrh may spread from its ordinary position, the larger tubes, to those of smaller calibre, and become a grave complication. The extension is most common in infants under one year, and in them usually proves fatal through collapse of the lung — a condition readily produced at this early age. The indicative symptoms are dyspnoea and rapid breathing, lividity of the face and extremities, a haggard and anxious expression of the countenance, and the detection, on auscultation, of fine subcrejiitant rales distributed throughout both lungs. After the age of twelve months catarrhal pneumonia is more frequent than extended bronchitis. It is, in fact, the most common complication of the dis- ease, and may occur at any time during its course. "When it arises early, the eruption is often delayed, or, if already present, may retrocede, and there is con- siderable aggravation of the general symptoms. If later — at about the time of the disappearance of the rash, for example — the temperature, instead of falling, remains high, ranging in the neighborhood of 102° F. : in place of the usual general improvement, there are greater weakness and more manifest illness ; the patient is listless and takes little interest in his toys or in what is going on about him ; there is increased thirst and anorexia ; the face is pinched and distressed-looking ; the lips are livid, and the al^e nasi move to and fro with the breathing, which is labored and quickened. On physical examination of the chest the ordinary signs of broncho-pneumonia can be detected. This compli- cation varies greatly in degree of severity. It often runs a prolonged, subacute course, and may terminate in complete recovery, in death, or, becoming chronic, may merge into one of the varieties of pulmonary phthisis. Intestinal catarrh, which is usually productive of nothing more than a trifling, readily-controlled diarrhoea, may be aggravated into an entero-colitis, or even an ulcerative inflammation of the mucous membrane of the colon. These complications are excited by improper food, by injudicious use of purga- tive medicines, and by careless exposure to cold and dampness-. They some- times appear during the initial stage, but are usually developed later in the disease. The symptoms are tumidity and tenderness of the abdomen, colic, tenesmus, and more or less frequent purgation, the evacuations being green in color and containing glairy or bloody mucus. The regular course of the disease is little aifected, though in nervous, sensitive children the intestinal lesions may maintain a temperature of 104° or 105° F. for several days after the subsidence of the rash. In such cases convalescence is prolonged, though 148 AMERICAN TEXT-BOOK OF DISEASED OF CHILDREN. the ultimate outlook is favorable unless catarrhal pneumonia coexists ; then the danger inherent to the latter condition is greatly increased. Laryngitis often complicates measles. It is most likely to occur during the decline of the eruption. Ordinarily the spasmodic form — false croup — is assumed, Avith symptoms that are alarming to the uninitiated, but really devoid of actual danger and without eifect upon the regular course of the disease. Sometimes, on the contrary, a pseudo-membranous exudation forms in the larynx, and the case at once becomes extremely grave. The symptoms are the same as in idiopathic cases. Thickening, softening, and ulceration of the mucous membrane occasionailly occur, and Rilliet and Barthez record a case in which suppuration about the larynx followed an attack of measles. Convulsions happening during the eruptive stage are of grave import; preceding it, they are seldom serious. Epistaxis, when it becomes profuse land exhausting, always tends to post- pone the restoration to health, and may determine death in weak subjects or when the disorder is severe and ataxic in type. Ophthalmia and otitis are infrequerit complications, and are almost entirely limited to patients having .tuberculous tendencies. Both yield sluggishly to treatment, and otitis may prove fatal by an extension of the inflammatory process to the membranes of the brain. Paralysis should be mentioned as a rare accident that may be associated with measles. Drs. Barlow and Ormerod have recorded cases in point. Sequelae. — Many of the conditions referred to as complications may also occur as sequels of the disease. Thus catarrhal pneumonia, laryngitis, and bron- chitis in chronic form, and chronic gastro-intestinal catarrh are frequent results. Enlargement of the bronchial glands is another common sequence, and acute tuberculosis so often follows that the physician must suspect its development whenever a patient remains feeble and feverish after an attack of measles. In children having a tuberculous diathesis the disease is very prone to light up any or all of the troubles which are characteristic of their constitutional taint. Other less common sequelae are "marasmus," or a condition of general wast- ing and debility ; diseases of the eyes and ears ; ulcerative stomatitis, with necrosis of the jaw ; gangrene of the cheek and vulva ; necrosis of the nasal cartilages ; and, rarest of all, renal disease. Whooping cough is generally supposed to bear an intimate relation to measles. Epidemics of the two diseases undoubtedly often follow close upon each other without any uniformity of precedence. What the actual connec- tion may be is uncertain, but it is probable that the presence of one exanthem merely lessens the resistance which a healthy body manifests to the infective power of the other. Diagnosis. — The distinguishing features of rubeola are the long prodromal stage with its marked catarrhal symptoms ; the course of the fever-curve, espe- cially the continuance of high temperature for two days after the appearance of the eruption ; and the peculiarities of the rash. It should be remembered, however, that the rash, though quite characteristic in typical cases, is more apt to be misleading, through its variations, than any of the other pathognomonic signs ; and it may be said of measles, as indeed of all other exanthemata, that a diagnosis must never be based exclusively upon the eruption. In the initial stage it is often difficult to differentiate between measles and an ordinary acute catarrh — a "severe cold." The coryzal symptoms are identical : hoarseness and cough are present in both, and both are attended by fever. If such symptoms are developed at a time when measles is epidemic, the probabilities are strongly in favor of an attack of the disease. On the MEASLES. 149 other hand, if the history of exposure to contagion is uncertain, it is best to withhold a decided opinion and wait for the appearance of the rash, which, it is well to recollect, shows upon the soft palate from twenty-four to forty-eight hours before it can be detected upon the skin. It may be stated here that this element of uncertainty in the early diagnosis is much to blame for the ready and wide extension of the disease ; for, while contagion is freely given off by patients in the catarrhal stage, isolation is rarely practised until all doubt as to the nature of the attack is cleared up by the eruption. Sore throat, which is sometimes present, combined with fever, may suggest scarlatina, but the latter disease has a sudden onset, with vomiting, rapid and extreme elevation of temperature, and very frequent pulse, and without catar- rhal symptoms ; further, the characteristic eruption appears not later than twenty-four hours from the commencement of the attack. In the eruptive stage, when the color and grouping of the papules are typical, and the fever, coryza and cough marked, there is little room for error. When the rash appears in hard, isolated papules, variola may be suspected, a mistake not uncommonly made. In small-pox, however, the pre-eruptive stage is characterized by obstinate vomiting and severe pain in the back. When the eruption appears, the temperature abruptly falls and the active symptoms abate ; the papules themselves are harder than ever noticed in measles, feeling like pellets of shot under the skin, and by the second day those first appearing on the face are changed into vesicles. There is more difiiculty in distinguishing the rubeolous eruption from the rash of rubella than from that of any other of the exanthemata. The points of distinction are the short, often featureless, prodromal stage of rubella, the comparative absence of catarrhal symptoms, and the fact that the papules are smaller and lighter in color, appear almost simultaneously on the face, the wrists, and the ankles, and thence extend over the body, showing no tendency to irregular grouping. Various skin eruptions, notably the early stages of acute and general eczema and syphilitic roseola, resemble the rash of measles, but the differences in clin- ical history and the entire absence of general symptoms render the distinc- tion easy. Prognosis. — Generally speaking, the percentage of fatality in rubeola is small. Nevertheless, in individual cases the prognosis depends upon the type of the epidemic, the age and previous condition of health of the patient, the nature of the hygienic surroundings, and the character aud severity of the complications. An attack, of whatever severity short of malignancy, occurring in a pre- viously healthy child over the age of two years, who is surrounded by the usual comforts of life and treated with ordinary skill, should almost invariably ter- minate in recovery ; and in such cases even the onset of so serious a compli- cation as catarrhal pneumonia is rarely fatal. Quite the reverse is true when the disease attacks children who are constitutionally feeble or debilitated by some antecedent acute disease, who are suffering from rickets or suppurative bone disease, who have chronic pulmonary lesions, who are subjects of the tuberculous diathesis, and who live in crowded and filthy houses or unhealthy localities. These patients, when they survive the force of the disease itself, are often carried away by one of the complications or sequelae, to the devel- opment of which they are very prone. In children under two years of age measles is more serious and the younger the infant the greater is the danger of an unfavorable termination. Here death is due to the readiness with which bronchial catarrh extends to the finer tubes, 150 AMEBIC AX TEXT- BO OK OF DISEASES OF CHILDBEX. producins Ciitarrluil piicunioiiia or piilinonaiT collapse — a tendency inherent to every catarrh in the very young, but most marked in that attending measles, and very apt to be exhibited in -weakly or rachitic infjuits. The"^ gravity of the difiVrent complications and the fatality of epidemics of malignant type have already been referi-etl to. In ordinary epidemics the prognosis becomes unfavorable under the following conditions : When the prodromal stage is more prolonged than usual and attended by violent symptoms of any kind, as great jactitation, irritability, dyspnoea, stupor, and coma or convulsions; when the eruption is irregular in development or course; when the pyrexia continues after the subsidence of the rash ; when in the later stages of the disease the face remains deeply flushed or grows pale ; when cough, dyspnoea, or diarrhoea persist, and when the child is left weak, languid, dispirited, or irritable. Dr. Ellis places the mortality of measles at 1 in 15 cases. My own experi- ence has been much more fortunate. In ])rivate practice all of my cases have recovered save one, and that, an iufiint of nine months, died of meningitis directly due to the active lighting up, by the measles, of a long-standing disease of the middle ear. Even in my hospital Avards the mortality has been less than that given by the author quoted, and the deaths, while occasionally due to the force of the poison on enfeebled bodies, have mainly occurred in patients previously affected with spinal caries or suppurating joints or having badly deformed rachitic chests. Before leaving this division of the subject some attention should be given to the question of the liability of the return of measles. The fact is, that, next to typhoid fever, measles is the most liable of all the exanthemata to return. A number of cases are on record in which patients have had a second attack after a short interval, and sometimes so soon after the first as to consti- tute a true relapse, both attacks running their course within a period of four or five weeks. Treatment. — Attention must be directed first to the hygienic manage- ment of the disease, as this is of vast importance in all cases, and in those of ordinary severity sufiices, with a very little aid from simple drugs, to ensure a favorable ending. As early as the nature of the attack can be decided upon the patient must be put to bed, and confined there until not only the rash itself, but all traces of the reuuiining yellowish-red stains, have disappeared — about the eighth or tenth day of the disease. Young infants. Avith whom it is difiicult to enforce complete rest, in bed. must, when taken up, be held upon the nurse's lap and be properly protected by some light wrap. If it be possible to have two cots, one for day and the other for night use, the patient's comfort is greatly increased. Care must be taken to provide only sufficient bed-covering to maintain warmth ; the mattress should be of hair, and, when only one bed is at command, the sheets ought to be changed at least once each day, though accidental soiling may render more frequent renewal necessary. A laro-e, airy, and, if possible, isolated chamber is to be selected for the sick-room, and an open fireplace for wood or coal is the best method of heating, at the same time securing free ventilation without, draughts. When heat is supplied from a furnace, change of air must be effected by a window or door, the patient being protected from chilling currents by a carefully placed screen. The proper temperature is (35° to 68° F. During the continuance of photophobia and conjunctival irritation the room must be moderately darkened, and it is always well to see that the bed is so placed that the patient's face will not be turned directly toward a window. All superfluous hangings and furniture MEASLES. 151 should be dispensed with, though it is unnecessary to strip the apartment so completely as in case of scarlet fever. After the child is well enough to leave his bed he should be kept in the sick-room for three or four days ; then, so far as his own safety is concerned, he may be allowed the i-ange of the house, but not permitted to go out doors for a week longer, and then only in fevorable weather. If, however, there are other susceptible subjects in the house, and the question is one of isolation, he must not quit his chamber until the end of the third Aveek from the beginning of the attack. The diet requires careful regulation. Nursing infants must be fed, during the febrile stage of the disease, at somewhat shorter intervals than in health, but if, on account of increased thirst, they suck very greedily, the time of lying at the breast must be curtailed, the object being to secure sufficient nourishment without at any time overloading the alimentary canal and over- working the digestive powers, which are enfeebled by the catarrhal condition of the mucous membrane. With bottle-fed babies it is even more essential to carefully regulate the axlministration and preparation of the artificial food. For example, a child of nine months, who in health would be fed five times daily and take in all about forty fluidounces of appropriately strong food, must during measles be placed nearly on the plane of a child six months old, the feedings being increased to six or eight a day, the total quantity reduced to thirty or thirty-four fluidounces, and the strength proportionally lessened. For the purpose of dilution lime-water or barley-water may be employed the advantage, on account of its power of preventing rapid coagulation and with formation of large, tough curds in the stomach. Should ordinary milk mixtures disagree, it is well to resort to Pasteuriza- tion or partial predigestion, and if it be impossible for the infant to retain any form of milk food, as is sometimes the case, raw beef juice in doses of two teaspoonfuls every two hours, or veal broth and barley-water may be resorted to as temporary substitutes. Patients who are old enough to take a mixed diet Avhen well should at once be placed upon liquid food. To relieve thirst, pure water, carbonic-acid water, and Vichy are prefer- able to any of the old-fashioned sweetened or acidulated drinks. They are to be given cool (not iced), and in moderate quantities at short intervals. In administering drink a good plan is to use a small glass — holding a fluidounce, for example ; to drain this gives the child more satisfaction than the same draught from a larger vessel which he is not allowed to empty, and there is much less danger of an excessive quantity being taken. With the decline of the temperature and the abatement of symptoms denot- ing gastro-intestinal disturbance, additions may gradually be made to the diet until the full feeding of health is resumed. Due attention must be paid to keeping the patient's person clean. To this end the face, hands, portions of the body liable to become soiled, and even the whole surface, should be sponged with tepid water every morning, each part being washed and dried separately, so as to avoid exposure and chilling. When the patient is well enough to go into the open air, it is essential to see that he is properly dressed with warm woollen under-clothing ; morning spongings with salt water may also be ordered now, and complete restoration to health will be greatly hastened by a change of air. So the atmosphere be dry and bracing, it makes little difference, in ordinary cases, whether the resort selected be at the sea-coast or inland, though the former is to be preferred when 152 AMERICAN TEXT-BOOK OF DISEASES OF CHILD REX. the disease leaves the subject with marked glandular enlargements or develops other manifestations of tiie tuberculous diathesis. The medicinal treatment of ordinary cases of measles is very simple. Early in the attack, while the temperature is elevated and the cough hoarse, citrate of potassium is useful as a febrifuge and relaxing expectorant. To a child six years old from one to two fluidrachms of liquor potassii citratis should be given every two hours, and to this may be added 20 drops of pare- goric and 5 or 10 drops of syrup of ipecacuanha if the cough becomes very troublesome and croupy — a tendency often exhibited during the first two or three nights of the attack. Later, as the cough grows loose, a stimulating expectorant should be substituted. The best of this class of drugs is chloride of ammonium, which must be given in solution and in doses of 1 to 2 grains every second hour. As convalescence approaches the expectorant may be gradually discontinued, and 1 grain of quinine may be given three times daily, either in solution or in chocolate tablets ; sometimes, too, there is sufficient debility to warrant the administration of moderate doses of whiskey. Finally, a course of iron or of cod-liver oil — in tuberculous cases — is often necessary. While pursuing these general measures the eyes need careful attention. Four times daily the lids should be washed with water as hot as can be borne, and afterward a few drops of a solution of borax (gr. x to f^j) gently applied to the conjunctivae. In case of great photophobia and conjunctival irritation a weak solution of cocaine (gr. j to f §ss) may be dropped into the eye twice daily- It is well also to spray the nares and pharynx at frequent intervals with DobelFs solution or Listerine diluted with water (1 part to 6), or, if the patient be old enough, the throat may be gargled every three hours with one teaspoonful of chlorate of potassium dissolved in 4 fluidounces each of claret and water. Mild counter-irritation of the skin of the throat is often of serv- ice in relieving pain and hoarseness ; for this purpose a combination of tur- pentine and olive oil (1 part to 2 or 3) may be employed several times in the twenty-four hours. Malignant measles demands a stimulant and tonic treatment. Whiskev or brandy in properly proportioned quantities must be added to the milk, or brandy-and-egg mixture may be employed, and raw beef juice and concen- trated meat broth must form an element in the diet. Of drugs, quinine, carbonate of ammonium, and digitalis are called for, and must be used in sufficient doses to meet the urgency of the indications. In this form mustard baths and hot packs are of great service. For the mustard bath, which is more suitable for children under three years of age, the water should be at a temperature of 100°, and contain about one tablespoonful of mustard to the gallon ; the patient is immersed up to the neck for three minutes, then quickly dried and placed in bed between blankets or wrapped in a blanket and dried later. The bath may be repeated in tAvo hours if necessary. In hot packing the child is placed between blankets, and then a blanket wrung out as dry as possible, after being wet with hot water or mustard and water (two teaspoonfuls to the gallon), is quickly wrapped about the body, care being taken lest it be too hot ; it may be renewed in half an hour. At times one or more of the symptoms of the disease may be so modified or exaggerated as to require special treatment. Headache, when violent, is usually attended by constipation, and can be relieved by unloading the bowels and by putting the feet in hot mustard- water (one tablespoonful to the bath) or applying a mustard plaster ( 1 part to 4 or 6 of flour) to the nape of the neck. For the purpose of evacuating the bowels enemata or glycerin suppositories should first be tried, and if these MEASLES. 153 fail, a mild laxative, as calomel in broken doses or milk of magnesia with aromatic syrup of rhubarb, may be administered. Active purgatives should never be employed, on account of the decided diarrhoeal tendency of the disease. Should these measures fail to relieve the headache, resort must be had to bromide of potassium or elixir of the valerianate of ammonium. Moderate looseness of the bowels need not be interfered with, but if the purging be sufficiently violent and continuous to threaten the strength of the patient, a combination of rhubarb, bismuth, and chalk mixture may be prescribed, or, if the evacuations be very watery, it may be necessary to use a more powerful astringenc, as oxide of zinc in doses of gr. ^| every three or four hours. Distressing vomiting is best treated by causing the patient to drink tepid water, and, when the stomach has been relieved of altered food and irritating secretions, applying weak mustard plasters to the epigastrium. In this condi- tion, however, it is most important to pay careful attention to the feeding. When the eruption is delayed, appears irregularly, or retrocedes, it must be remembered that the condition depends upon some complication — broncho- pneumonia, for example — and that the true mode of relief is to relieve the internal inflammation which is the cause of the difficulty : hot mustard foot- baths or full baths, hot packs, mustard sinapisms, and stimulants are required. Liquor ammonii acetatis is a useful preparation in these cases ; it may be given in doses of one to two teaspoonfuls every two hours. When the rash itches or burns, frequent applications of fresh lard or vaseline will afford relief. At the acme of the eruption the temperature often runs up to 104° or 105° F. for a few hours, without corresponding severity of the other symp- toms. No interference is necessary for a temporary elevation of this sort, but for a persistently high temperature of twelve hours or more some antipyretic must be given or cooling baths resorted to. Antipyretics are still on trial, but the safest is phenacetin. This may be administered in an initial dose of 1 grain for any age between two and six years. If the temperature falls after- ward, wait and observe the extent of the depression; if not, repeat the dose after the lapse of an hour ; should this fail, gradually increase the amount to 2 or 3 grains. The first dose may be given when the temperature ranges above 103°, and the drug may be repeated as often as necessary to keep it below this point, the cardiac condition being carefully watched in the mean time. When baths are employed to reduce the pyrexia, water at a temperature of 95° to 98° F. should first be used ; if this fail, tepid or cold spongings may next be resorted to, and as a final resort the tepid or cooled bath may be tried. In giving the latter the child should be undressed as quickly as possible, and then immersed in a bath of 90° F. ; cold water is now rapidly added until the temperature of the bath is reduced to 80°. After a sufficient intermission — usually five or six minutes — the body is quickly dried with a soft towel and the patient put back to bed between sheets. The effect of the bath is sometimes very powerful, and the child remains livid-looking and collapsed for some time. In such case small doses of brandy must be given in warm milk at short intervals and artificial heat applied to the feet. It is stated by some authorities that antipyretics ought to be employed whenever the temperature reaches 102° F. Such a rule is dangerous. There are many instances in which, with a temperature of 102°, the child is very ill, and this degree of fever may be judged to be more than usually detrimental. For these a bath, either tepid or cold, cold sponging, or phenacetin, may be 154 AMEIUCAX TEXT-HOOK OF DISEASES OF CHILDREN. recomnieiRkHl, but for one such case there are many others that run a perfectly fav()ral)le course ^vith a temperature even higher than this, and in which it is difficult to see what benefit could have accrued from antipyretics. Each case must be treated upon its own merits. When in doubt as to the propriety of using antipyretic drugs or baths, it is well to try the effect of moderately full doses of sulphate of quinine. It has been my ow'n experience that this agent given by the mouth, or, better still, by the rectum, in suppositories of two to four grains every three or four hours, freciuently reduces temperature, and, should there be umch associated restless- ness, produces sleep. The treatment of convulsions, broncho-pneumonia, and other disorders which may be associated with or follow after measles does not differ from that employed when these affections occur idiopathically, and therefore requires no especial consideraticm here. Quarantine.^The ru])eolous patient should keep his bed for eight or ten days and his room for three weeks; then, if he be quite well in every respect, there is little danger in his mixing with his playmates. When one member of a household is attacked, it is necessary for the other children of the family who have not had the disease to stop going to school or associating with other children, as it is probable that they also have contracted the malady, and, as it is infectious in its early stages, they may readily be the means of giving it to others. For the same reason it is unwise to send them aAvay from home ; at the same time they must not come in contact with the case already developed. The convalescent should have a warm bath and fresh clothing before ming- ling with his associates. Scalding of the bed- and body-clothing and thorough airing and cleaning of the sick-room are all that is necessary in ordinary cases, though in malignant epidemics disinfection of the bedding and thorough fumi- gation of the chamber with sulphur should be insisted upon. ft SCARLET FEVER. By MARCUS P. HATFIELD, M. D., Chicago. Scarlet fever, or scarlatina, is a self-limited, contagious, microbic disease, characterized by fever, angina, and a typical eruption, and followed by des- quamation and recovery in about three weeks if the disease be uncomplicated. The health reports of all of our large cities show that scarlet fever is an endemic disease of childhood, never being entirely stamped out, and affecting now only a trivial percentage of the population, and then increasing into epi- demics of frightful mortality, often from causes as yet unknown to modern science. According to Busey, it is the most widely disseminated of the exanthemata of childhood, and, perhaps rightly, the most dreaded of all the diseases of children, whose susceptibility varies not a little with their age. Infants under six months, as a rule, escape ; 64 per cent, of all cases occur in children under six years of age (Murchison), after which susceptibility diminishes, though liable to as yet inexplicable variations, for children and nurses who have escaped half a dozen epidemics may succumb to the seventh after exposure apparently in no wise different from that which preceded it. One attack, as a rule, protects from a second, though well-attested returns are on record. The majority of those cases popularly reported as second attacks are usually due to errors in diagnosis. But it must also be remembered that frequent abortive actacks of sore throat are well known to occur in nurses or physicians attending cases of this disease. Scarlet fever may be complicated with other of the exanthemata, especially varicella. Cases of coincident scarlatina, variola, and measles are reported by Vogel. While the disease is not so infectious as measles, as shown by the fact that 42 per cent, of Budert's unprotected children escaped infection during an epidemic in the isolated German village of Neundorf, it should be remem- bered that the contagiousness of scarlet fever varies greatly with the epidemic. Brush's statement that the colored race possesses an immunity from this disease is erroneous, for the writer has seen scarlet — or rather royal purple — fever in a coal-black pickaninny, and in Chicago, at least, colored children enjoy like privileges in this respect Avith those of lighter skin. History. — It is more than probable that scarlet fever must have existed as far back as there have been masses of people crowded together in great cities ; but there are no earlier accounts of the disease than those of the seventeenth century (1610— 18), when epidemics occurring in Spain and Italy were described by Mercatus, Heredia, and Syambatus (Bohn). About the year 1625 both sporadic and epidemic cases were met with in Breslau and described by a Dr. Coring, who is probably entitled to the honor of being the first German author to write on this subject. He was closely followed by Sennert's description of 155 156 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. the disease at Wittenberg, later followed by like outbreaks at Brieg (1642), Schweinfurt (1652), and in Poland (1664). " Up to the time of Sydenham scarlet fever was supposed to be a variety of measles, being known by such fanciful terms as " ingrassius, rosalia, rubeolas, morbilli ignei," etc. During the years 1670-75, Sydenham had ample oppor- tunity to study the epidemics raging in the city of London, and difierentiated the disease from measles. The origin of the name is yet uncertain (Bohn). To Fothergill (1750) justly belongs the credit of establishing the con- tagiousness of scarlatina, and the facts upon which depend all modern theories of its prophylaxis. But many writers believe that the disease has steadily in- creased in virulence, until to-day it is the most prevalent and dangerous of all the diseases of childhood. Scarlet fever is supposed to have been brought to North America in 1735, spreading slowly from the coast inland, and so infrequently met with that Dr. Rush, as late as the beginning of the present century, wrote : " No physician would be likely to see it more than once in his lifetime." At first it was regarded as ratlier a trivial aifection, but malignant epidemics swept through Kentucky and Ohio when the country was almost an unbroken forest. Then came a period of slight malignity, so that Professor Chapman of the University of Pennsylvania so late as 1833-36 positively denied the contagiousness of this disease. Etiolog-y. — He would be a purblind physician who, in these latter days, would attempt to deny the microbic origin of scarlet fever, but it must as frankly be admitted that our knowledge concerning its exact etiology is as yet indefinite and conflicting. Klebs figures the peccant microbe and names it Monas scarlatinosum. Ecklund of Stockholm minutely describes another, w^hich he is certain is the cause of scarlet fever, and proposes the name Plox scindens, a fuller description of which may be found under the heading of Pathology. Edington of Edinburgh later isolated from the blood and epi- dermic scales of scarlet-fever patients another microbe, which he and Dr. Shakespeare of Philadelphia unite in declaring to be the specific cause. But, while it is disheartening that as yet we know so little accurately con- cerning the bacteriology of scarlatina, there is much that is well known and proven beyond dispute in regard to the spread of the disease and the nature of its contagion. First of all, it can be insisted upon that its contagium vivum is easily portable, tenacious in its poAver to do evil for years, and with great probability originating in some of the lower animals. The horse, the dog, and the cow all have had their claims advanced as first owners of the scarla- tinal microbe, and during the Hendon epidemic some years since it seemed as if the question had been decided in favor of the cow. Later and more accu- rate investigations, however, seemed to show that the disease carried from the diseased teats of the infected cows was scarlatinal only in the form of the rash communicated to human beings. There is also considerable dispute as to which of the secretions may carry the scarlatinal virus. Some writers insist that the patient is a source of infec- tion from the initial sore throat until the last branny scales have dropped away from between the fingers and toes ; others, that infection may be carried so long as there is a specific otorrhoea. Undoubtedly, the micro-organism usually enters the system by inhalation, but there seems to be good reason for believing that it may be taken in with food (Smith), or carried from person to person by inoculation of scarlatinal blood or blood-serum. It is, however, generally conceded that a scarlet-fever patient is most dangerous during the stage of desquamation, and that the bi*anny scales of this period PLATP] VI.

SC ABLET FEVEB, 157 are the most frequent carriers of the contagion, though others claim like dangerous properties for mucus, urine, and the faeces. It is certainly true that the contagion of scarlet fever may be carried by almost every conceivable article of apparel or material used about the sick, for next to the vai'iolous microbe the scarlet-fever contagion preserves its vitality for a longer time than any other of the exanthematous poisons. Dr. Holland relates an extraordinary case where the virus survived two generations, being packed away in clothing in a chest for thirty-five years, at the end of which time it communicated the disease to a grandchild for whom some of his grandfather's clothing was made over. To the writer's knowledge, the disease remained hidden in a fur cloak packed away for more than a year, and then communicated the disease to an entire logging community isolated for the winter in the wilds of Northern Michigan. Hence the exact origin of any given case of scarlet fever is often most difficult to accurately settle, especially Avhen we remember the possibility of the disease being carried by books, letters, or toys from some previous case. Next to library-books, letters, clothing, and toys, milk seems frequently to be the medium of contagion. In one instance milk is known to have carried scarlatina to one-half of the families to which it had been delivered, although it had not been touched by the milkman or other members of the infected family (Taylor) ; and in another the disease was carried to all the families served save one, which consisted only of elderly people (Bell). Powers and Klein still teach that the disease originates from the sore teats of infected cattle suffering from bovine fever, but, after much heated discussion on the subject, it appears that the disease thus communicated is modified cow-pox rather than true scarlet fever (Hendon epidemic, 1885). The persistence of the scarlatinal virus in clothing and apartments after ordinary methods of disinfection is sometimes amazing. J. Lewis Smith relates the case of a Sunday-school librarian who contracted the disease from books returned from an infected tenement-house. One month after his recovery the room in which he had been sick and his clothing were disinfected with burning sulphur, and yet he succeeded in carrying the disease personally to his sisters after a journey of three hundred miles to an isolated country town, to which they had been quarantined. These sisters infected the room in which they were confined, so that children visiting it, after its disinfection, in turn contracted the disease. The writer knows of a building in the city of Chicago in which, in three successive years, the children of the families moving into the house con- tracted scarlet fever in spite of yearly domestic disinfections. Mode of Transmission. — Although it is usually believed that the scarlet- fever poison is not volatile and cannot be carried by the atmosphere solely, the case sketched in the description of Fig. 1, contributed by an intelligent medical student, apparently contradicts previous statements on this subject. Bacteriology. — Illingworth still claims, I believe, that the germs of scarlet fever are set free during the fermentation of animal and vegetable refuse. The inhalation of these causes them to lodge upon the mucous membrane of the throat, where they propagate, and, by the reabsorption of their products, pro- duce the other lesions of scarlet fever. Almost all other authorities believe that there is a specific scarlet-fever microbe, which requires a previous human being for its host. Repeated efforts have been made to isolate this micro- organism. As early as 1882, Ecklund of Stockholm thought he had discovered it in the form of colorless discoid corpuscles, about one-tenth the size of the red corpuscle, and found in immense numbers in the urine of scarlatinal patients. These he named Plox scindens. He states that he had found them 158 AMERICAN TEXT- BO OK OF DISEASES OF CHILD BEX. in vast numbers in the soil and ground-water of the island of Skeppsholm during an epidemic of scarlet fever there. Their presence seems to be well proven, but their relation to scarlet fever is by no means as definite. More Fig. 1. N W " The above rude map shows the relation of, and distance between, several houses in the township of Clare- mout, Minn., one inch representing a mile. In the house A lived Wm. Connell. During February of 1879 one of his children contracted scarlet fever through a letter that came from relatives in Toronto, Canada. About three days later a second child came down with the disease and died on the ninth day. The wind had been blowing from the north-east, and about this time my younger brother came down with the disease in house No. 4. Young James Connell was buried on the day after his death; and on that day the wind changed into the north-west, where it continued for some time. The bed- ding and clothes of the Connells were hung on the clothes-line to air, and in about one week from that time the children in house X6. 3 were taken with the disease. In house No. 2, thirty rods north, there were five children, in house No. 6 there were four children, and in house No. 5, two children. All of these escaped the disease. There was absolutely no communication between the houses on account of the cold weather and fear of the disease. Two years later there came an epi- demic of the disease in that vicinity of a severe type, and all the children in the neighborhood had the disease, except those that had had "it two years previously." hopeful are the results of Dr. Edington of Edinburgh, who began in 1886 to make investigations of the blood and epidermis in human scarlet fever. He succeeded in isolating a diplococcus scarlatinie sanguinis and a bacillus scarla- tina. Inoculation of the bacilli produced in rabbits erythema and desquama- tion; in calves, fever and a rash, folloAved by desquamation. Dr. Edington says "the bacilli measure 1.2 to 1.4 micro-millimetres in length and 0.4 micro- millimetre in width, and are found in the blood during the first two days only, in the desquamating epidermis only after the twenty-first day, and in the eighteen intermediate days they cannot be demonstrated in any of the tissues." His results have been confirmed by Dr. E. 0. Shakespeare, who proposes the provisional name of baciUns scarlatinfe for this micro-organism, and reports that. " sown on gelatin-plates, it forms little points of liquefaction after several days. Sown in test-tubes of Koch's jelly, it rapidly liquefies it, but with no distinct growth-formation. The fluid thus formed is crowded with the motile bacilli, but a pellicle is not formed until the liquefaction is well advanced." This occurred in every case but one of the tubes made from the desquamation if taken after the termination of the third Aveek, but never before this. It also occurred in every tube made from scarlatinal blood if taken before the third day of the fever. Inoculation upon rabbits produced erythema, best marked in the old. and in from two to five days a fine desquamation, which lasted for a Aveek to ten days. Temperature, 103°-106° F. Similar results were obtained from guinea-pigs, except that the desquamation was more copious and the hair fell out if pulled upon. "A calf Avas then inoculated, and at the same time oriven some of the SCARLET FEVER. 159 culture in milk. The calf was in good health at the time, and had a tem- perature of 99.5° F. Six hours from the inoculation the calf developed great sickness, and the temperature taken in the axilla registered 103° F. [This was at 10 P. M.] The calf was then left for the night, but in the morn- ing was found dead. Small portions of the spleen and kidneys were taken from the animal, placed in Koch's jelly, and allowed to incubate, and developed the chai-acteristic bacillus previously described. A second calf was inoculated, when only one day old, with the bacillus, care being taken that the inocula- tion was made with the absolutely pure material. Previous to the injection the calf's blood was examined, and found to contain no organisms. The inocula- tion was made in this case with a very carefully sterilized hypodermic syringe. At 6.30 p. M. this was performed, the temperature per rectum then being 99.6° F. At 10 p. M, the animal took milk freely, and the temperature re- mained practically the same. Next morning, temperature 104° ; sickness, slight diarrhoea, and great prostration, and the throat inflamed. In the after- noon the skin of the thorax, upper abdomen, and inner side of the foreleg pre- sented a general redness, increasing toward evening (T. 102.8°). The next morning the animal was better, but rash still vivid, throat and posterior part of the tongue inflamed (T. 102°), From this time the beast steadily improved, and on the sixth day desquamation set in." The same bacillus, according to Dr. Shakespeare's report, may be obtained from the blood of a scarlet-fever patient during the first two or three days of the disease, and from the desquamating scales on the twenty-first day in an ordinary case; if malignant, they may be obtained earlier. These bacilli rapidly increase in warm milk, which they may thus infect. " The rapidity of the growth of this organism — which is such if one in- oculate a flask of broth the diameter of which is two inches and a half, and if it be incubated, the pellicle will develop and cover it entirely over in the course of four hours — suggests an explanation of the short incubation of scarlet fever when furnished a proper pabulum." Such, it seems to the writer, is a fair statement of our present knowledge on the subject, to be confirmed or reversed by later investigations. Patholog-y. — Aside from its bacteriology, still in dispute, there cannot be said to be any pathological changes pathognomonic of scarlet fever. Autopsies made upon those dying in the earlier days of the disease show only the local lesion of the throat and engorgement of various internal organs, especially the intestines and brain. Deaths occurring later are generally due to septicaemia or nephritis. The former are apt to show secondary pneumonia and metastatic abscesses, and the blood coagulates poorly and is prone to form clots in the right ventricle. The characteristic changes of pleurisy, pericarditis, endo- carditis, purulent meningitis, empyema, or pulmonary gangrene may be found in these cases. The kidney lesions are those of an acute exudative (Delafield) or glomerulo- nephritis (Welsh), the latter being the true post-scarlatinal nephritis. In such cases " the liquor sanguinis and the red and white blood-cells escape from the renal vessels into the tubules. Swelling or necrosis of the renal epithelium, with changes in the glomeruli, occurs." Macroscopically, the kidneys are large and flabby, and the cortex is thick and pale, with injected capillaries. The tubal epithelium is swollen and opaque. Hyaline cylinders identical with the casts are found in the convoluted tubes, and more abundantly in the straight tubes, along with irregular masses formed from the exuded blood-plasma. In the tubes are also red and white blood- cells. The glomeruli exhibit important changes. They become larger or more 1(50 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. opaque, due to the swelling and growth of the cells on and in the capillaries, '' for tlie glomerular capillaries in their normal state are covered on their out- side by nucleated cells, and flat cells line their inner surfaces in places, not continuously. On account of these cellular changes, the individual capillaries in the glomerulus become indistinct, but the main divisions of the tufts are visible. In very severe cases the growtli of the cells on the tufts is so con- siderable that they form large masses of cells between the glomerulus and its capsule. The walls of the arteries in the kidneys may be thickened by a swelling of their muscular coats, and the Malpighian bodies may stand out like grains of sand." This connective-tissue growth Delafield considers characteristic, "involving not the Avhole of the kidney, but symmetrical strips or wedges in the cortex, which follow the line of the arteries. These wedges are small or large, few or numerous, regular or irregular, in different kidneys, but in every wedge we find the same general characters : one or more arteries, of which the walls are thickened; glomeruli belonging to these arteries, with a large growth of capsule; cells compressing the tufts ; a growth of new connective tissue in the stroma around and parallel to the arteries. Between the wedges we find at first only the changes of exudative nephritis ; later, a diffuse growth of con- nective tissue. If the nephritis is of acute type and longer duration, the tissue is denser and has more basement substance. Where the growth of the new tissue is abundant the tubes become small and atrophied. The exudation from the blood-vessels is very considerable, so that the urine contains large quantities of albumin, many casts, and red and white blood-cells" (Delafield and Prudden). The irregular distribution of these kidney lesions, according to Bartel, explains the contradictory results often obtained by successive examinations of the urine. There may be parts of the kidney which entirely retain their functions, and from these normal urine may be secreted. But that a scarlatinal dropsy may exist from beginning to end without the presence, at any time, in the urine of either blood, albumin, or casts, is as improbable as that dropsy may occur Avithout nephritis (Bohn). Incubation. — Formerly a week or ten days was given as the usual length of the stage of incubation ; later writers, however, fix it at two to five days, and it may, in malignant cases, last not more than twenty-four hours. But it is often difficult to say exactly when the stage of incubation ends and that of the initial sore throat begins. Murchison's table (Smith, p. 275) shows that in the great majority of the cases reported by him the stage of incubation was within five days, and the latest writer on this subject says that if the initial vomiting be taken as the conclusion of the stage of incubation, it will be found to be under three days (Ashby, p. 248). Symptoms. — The onset of scarlatina is usually so abrupt that its begin- ning may be fixed with considerable definiteness. There is possibly a pre- vious slight duskiness of the skin, chilliness and malaise, but usually the first thing that attracts attention is vomiting, often without any relation to a previous meal ; or there may be diarrhoea. Older children may not actually vomit, but complain of nausea, languor, headache, and sore throat, and feel chilly, although the face is flushed, and the thermometer may show a tem- perature as high as 103°-105° F. If such children are also drowsy, they may become delirious in their sleep. The pulse is full and strong (120-160), the skin is hot and dry, and the throat feels stiff and uncomfortable, and, if examined, will show a characteristic punctate redness. Such is the ordinary onset of a typical case of scarlet fever, but there is no disease of childhood that is liable to wider and more eccentric variations in its onset and course, PLATE VIII. SCARLET FEVER. SCARLET FEVER. 161 oscillating between the very slight abortive form and that frightful variety- called by the French foiiclroyant, or scarlatina fulminans, fortunately rarely met with ; for in such cases the child succumbs, mortally poisoned from the very first by the virulence of the scarlatinal virus, without any prodromal stage or hardly any symptoms except those which may be referred to the nervous system. These dreadful cases often run their entire course in from thirty-six to forty-eight hours without eruption or sore throat, the only symptoms being nausea, dizziness, loss of consciousness, coma, violent delirium, or convulsions attended with abnormally high temperature (107°). Scarlatina simplex may be differentiated in twenty-four hours by the ap- pearance of the typical scarlatinal rash in the form of a scarcely perceptible scarlet flush or pin-point eruption, very closely resembling in color and stip- pling the shell of a freshly-boiled lobster. The eruption usually begins on the neck or cheeks or small of the back, and ought in forty-eight hours to spread nearly over the body, either as a well-defined blush or in scarlet patches — scarlatina laevigata. Plethoric and blond children develop the rash most promptly, and in all cases its color is heightened by the warmth of the bed, by hot baths, or by crying. A characteristic white line remains for a few seconds after drawing the edge of the nail or the point of a pencil over the rash. This typical line is supposed to be due to a paralysis of the vaso-motor Fig . 1 Dai/ 1 2 3 4 5 6 102 101 100 99 98 ^96 Pii/se St ■« Qi !5s CO ^ "? 1 1 A k j:^ g c / \ i \ A N A «^ \ > 1 V y /'• ^ V \ \J \ h V J \ J V v CO 2 CO 00 Temperature Chart in a Mild Case of Scarlatina.

Until the eruption is well marked the fever continues high, often dangerously so, as it is not unusual to find the temperature in impressible children marking 105°-107° F. The pulse is quick and sthenic, except in cases of scarlatina maligna, where there may be general depression, delirium, and collapse from the very onset of the disease. The pulse, as a rule, is faster than the temperature would apparently call for, ranging from 130—150, its relation to the rash and temperature being well shown in the accompanying chart, taken from Ashby (Fig. 1). Pharyngitis, with more or less soreness of the throat, is always present, although it may not be sufficiently painful to cause the child to complain (scarlatina sine angina). The respira- tory organs, except the throat, are rarely involved, so that cough is generally absent. When present, it is due to faucial irritation, except where pneumonia occurs later as a dangerous complication. The tongue is the so-called straw- berry tongue — that is, covered with a white fur with bright red tip and borders. 11 \ 162 AMEBIC AX TEXT-BOOK OF DISEASES OF CHILDREN. When the papilh^ are greatly swollen, they cause the granular appearance known as the raspberry tongue. Some writers speak of a pathognomonic sweetish odor of the breath which may be detected at this time, but this is by no means an invariable symptom nor one upon which much reliance should be placed. In a simple, uncomplicated case the fever and all threatening symptoms moderate with the appearance of the rash, with the exception of a slight even- ing febrile exacerbation, and any variation from this rule betokens malignancy or some new complication. From the fourth to the sixth day desquamation ordinarily begins. Those areas which are first reddened fade in like order, and. as the color disappears, Fig. 2.

These scales drop off imperceptibly, except when from itching, as is apt to happen on the face and neck, they are scratched off, and the tender epidermis beneath becomes cracked. In such cases the scales may be throAvn off in shreds, or casts of the entire lip, fingers, or palms of the hand may be shed. A like desquamation occurs from the membranes of the throat, trachea, kidneys, and intestines, though of course the epithelial scales in these localities are carried away in a softened, macerated condition.

A dull, apa- thetic condition is, as a rule, more to be dreaded than the usual restlessness, which is due to continued reflex irritation of the rash. In hypersesthetic chil- dren this produces twitching, or even eclampsia, which is graver the later it occurs in the disease. Variations. — We have previously described what might be considered a typical case of uncomplicated scarlet fever, but, unfortunately, uncompli- cated cases are so rare that there is no disease of wider variations in every symptom. The eruption may be so light as to escape detection, or, on the other hand, instead of the ordinary scarlatina laevigata, the eruption may appear in the form of small nodules {scarlatina papulosa), in which the papillae of the skin are swollen, and the whole body looks as if covered with goose- skin. Or, again, these papillae may become covered with vesicles, and we have that form of scarlatina which is known as searlathia 7niliaria. Should these vesicles become merged together, they give an eruption to which the name of scarlatina pemjohigoides seu bullosa is given. Such variations are found most frequently on the face, and are usually of grave import. Vogel reports excep- tional cases in which the eruption was intermittent in character, appearing only at certain times of the day, and for this he proposes the name of scarlatina intermittens. Lastly, we may find that fatal form to which the name of scar- latina petechialis seu hcemorrhagica has been given, where there is an actual extravasation of blood into the skin, and hence the popular name of " black scarlet fever" by which it is sometimes known. In nervous children it is not infrequent to find urticaria accompanying scarlet fever, masking the character- istic rash. Vogel also reports a curious variation of scarlatinal rash in which are found sharply-marked, isolated areas which remain milk-white in color, or at least much whiter than normal integument, due to a temporary paralysis of the arterioles similar in character to that which follows the thumb-nail mark on the normal scarlatinal flush ; but they are more persistent in character and are usually of unfavorable portent. Any intercurrent disease, as entero-colitis, which produces a determination of blood from the surface of the body, may greatly delay the appearance of the rash or render it so light that its dif- ferentiation will be difficult. Complications. — Throat. — The angina of scarlet fever may assume any form, from simple catarrhal injection to extensive necrotic destruction of tissue. Ordinarily, a bright red flush, with punctate marks, such as might have been produced by a small brush dipped in red ink and dotted over the pillars of the fauces, is the earliest and one of the most characteristic symptoms of scarla- tina. This may proceed no further than to give slight difficulty in swallowing and to impart a nasal tone to the voice. But, on the other hand, and more frequently — especially if pharyngeal disinfection is not practised from the very first — the swelling becomes so great as to make swallowing almost impossible. In such cases fibrinous exudates appear on the tonsils and fauces, and should the inflammation not be limited to the palate and fauces, the exudate may ex- tend into the post-nasal cavities, the larynx, and even into the oesophagus and stomach. More frequently it proceeds through the Eustachian tube into the intei^nal ear. (See Otitis Media.) The difl"erentiation between the fibrinous exudate of scarlatina and true diphtheritic membrane is by no. means easy, the more so since undoubtedly true diphtheria is not infrequently grafted upon the necrosis of scarlatinal angina ; but it may be helpful to remember that the exudate of scarlatina is yellowish and pultaceous, rather than the ashy-gray membrane of true diphtheria. Should the presence of Loeffler's bacillus 164 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. be finally accepted as pathognomonic of diphtheria, the differentiation may then be made absolutely; whereas at present we must frequently remain in doubt, since the removal of the scarlatinal exudate leaves the superficial layers of the pharyngeal mucous membrane denuded and bleeding exactly as in diph- theria. A similar gangrenous process may proceed upward into the pharynx or along the Eustachian tube into the cavity of the middle ear, with all the perils of purulent meningitis which this implies. Similarly, as in true diph- theria, the exudate may pass downward into the larynx, where its presence is made known by a chai'acteristic croupy metallic cough. If the exudate attacks the nasal cavities, this is attended by a profuse excoriating discharge, which soon grows purulent and offensive in odor. Adenitis. — All forms of scarlet fever are attended with inflammation of the lymphatic glands of the neck, and, as a rule, it will be found that the involve- ment of these glands bears a direct relation to the severity of the throat lesions. So we find all grades of adenitis, from the slight induration Avhich may be found accompanying all varieties of scarlatina, to a brawny swelling of the glands and cellular tissue embracing the whole neck. Such extensive mischief betokens like serious necrotic processes taking place within the pharynx, where the poisonous ddbris clogs and inflames the lymphatic glands, their pres- sure and morbid processes inflaming contiguous tissues. This cellulitis may extend from ear to ear, until deglutition becomes difficult and wide opening of the mouth impossible. If relief does not come early by resolution, the widely- distended tissue gives way to suppuration or gangrene, and death from haemor- rhage or septicpemia occurs. Scarlatinal Arthritis is not infrequently met with in certain epidemics of scarlet fever during both the eruptive and the desquamative stage. This form of arthritis attacks by preference the knee- and elbow-joints, and scarcely can be distinguished by its objective symptoms from ordinary articular rheumatism, being, like it, excessively painful. But arthritis rheumatica rarely ends in pyaemia or permanent articular osteitis, as arthritis scarlatinae is very prone to do. Diarrhoea and Dysentery are not at all infrequent complications after the crisis of the disease, probably being caused by desquamation of the intestinal epithelium, analogous to that which undoubtedly occurs in the tubuli uriniferi at this time. Scarlatinal Nephritis. — Last and, justly, the most dreaded of the com- plications of scarlatina, is that form of nephritis which so frequently occurs during the course of the disease that it may almost be considered pathognomonic ; for a mild grade of renal catarrh is as constantly present as is desquamation (Steiner). It is true this frequently escapes observation and passes on to re- covery without special treatment, but its existence is always a potential cause of morbus Brightii scarlatinosus, which should be considered not as a distinct disease, but as an intensification of the previous catarrh of the tubules brought about by chilling of the skin, etc. (Bohn). Similar nephritic catarrh has been noted in measles, small-pox, pneumonia, and other diseases, induced, as the writer believes, by the passage through the kidneys of irritating ptomaines generated in the body by the specific microbes of these diseases. The excretion of these or analogous compounds through the skin very likely gives rise to the characteristic rash, hence analogous lesions might be inferred for the kidneys. It is a well-known fact that the lighter the cutaneous rash the more liable are the kidneys to be seriously implicated, pre- sumably from increased excretion of various ptomaines thi-ough organs now endeavoring to do the work of both skin and kidneys. Daily examination of SCARLET FEVER. 165 the urine should be made for at least t^vo weeks in even the mildest cases of scarlet fever, and will show from the beginning of the eruption evidence of renal catarrh (epithelial debris and albumin), although the kidneys are appar- ently working normally. While the urine is high-colored and deposits copious urates, Dr. Gee claims that urea is not necessarily diminished. The chloride of sodium is lessened until the fourth to the sixth day, and phosphoric acid after crisis; while the urates or uric acid appear to excess during convalescence. In other cases the urine is cloudy, and contains fatty renal epithelia, more rarely hyaline casts, and red and white blood-corpuscles (only exceptionally albumin), all of which disappear usually with the disappearance of the erup- tion, but may progress to an actual catarrhal nephritis. This renal catarrh Bartel believes is due to a specific poison — ptomaine (?) — circulating in the blood, which poison irritates the tubules of the kidneys in its passage through the Mal- pighian tufts, either directly or from irritating properties imparted to the urine before its percolation through the tubuli uriniferi. Others claim that the source of this irritation lies in certain specific micrococci circulating in the blood, being analogous to diphtheritic nephritis, which Oertel thinks due to bacterial emboli. A diminution in the quantity of the urine is often the first thing that awakens the attention of the physician, if he makes it his duty, as he ought, to keep himself posted daily until the end of the third week. The normal amount of 800 to 900 c.c. per diem may fall suddenly to 100 or 50 c.c, or even less. Its color is yellowish-red, sometimes almost yellowish-green when cooled ; turbid, or clearing up on standing, depositing a cloudy precipitate made up of kidney cells and casts, urates, and uric-acid crystals in varying propor- tion. At times the urine is blood-red or smoky brown, from the blood it con- tains. Under the microscope the precipitate is found to consist of varying quantities of kidney epithelia, partly normal and partly swollen and distended, cloudy, and undergoing fatty degeneration. Besides these there may be vari- ous forms and phases of casts, lymph-corpuscles, red blood-corpuscles, and the crystals of urate of sodium and uric acid. The quantity of albumin found in urine is deceptive, since Jn certain epidemics of scarlatina, even where dropsy suddenly appears, often only faint traces of albumin may be found in the urine. Or albumin may be entirely absent during certain times in the day, or even for several days at a time, or during the greater part of the disease. Or, again, unmistakable albuminuria may be present while the urine is clear and free from all other abnormal elements. It may even happen that frequent analysis of the urine for days may fail to show either casts, epithelial cells, or crystals, while all of these, together with albumin, may be found at a subsequent exami- nation. Scarlatinal dropsy is often the first warning of the existence of any kid- ney lesion in mild cases which are supposed by parents, and even by the phy- sician, to be well along in convalescence. As a rule, the chief danger of scarlatinal nephritis lies about the end of the second week or during desquamation, though dropsy may appear as late as the fifth or sixth week. The first symp- toms noticed are slight oedema of the face and swelling of the eyelids. These are followed by pufiiness of the backs of the hands and feet, sometimes uni- lateral, with dropsical enlargement of the abdomen. In the case of children who have not yet been allowed to rise from their beds the anasarca is often most marked in the back and in the genitals, which may become frightfully swollen and sensitive. As a rule, the kidney complication is ushered in with a return of fever, or an increase in fever, if it still be present. But there is also a feverless nephritis, without subjective symptoms, loss of appetite, or anything abnormal that can be detected. In other cases there is only an evening 166 AMERICAJS^ TEXT-BOOK OF DISEASES OF CHILDREN. increase of temperature and pulse. Generally the skin is dry and ceases to desquamate. Pain over the kidneys is seldom complained of, unless questioned about or obtained by pressure. If the disease in the kidney is limited, there may be only a localized oedema, such as hydrothorax, hydrops pericardii, oedema of the lungs, or dropsical effusions into joints. This localized oedema may follow a brief apparent convalescence, during which children recover their appetite, and exhibit no features of illness, unless it be the persistence of slight lassitude and fever at night. After exposure to cold such cases develop anorexia, depression, and pain over one or both kidneys. The amount of urine is greatly diminished. It is concentrated, high-colored, and contains albumin and casts, and may not measure more than an ounce for the entire day, or may even be completely suppressed. About 6 per cent, of all scarlatina patients suffer from post-scarlatinal nephritis, the course and duration of Avhich depend directly upon the extent of the anatomical lesions of the kidney. Very light cases recover in a few days. Generally the anasarca and effusions increase for several days — say a week and over — breathing being hindered by the ascites and pleural eftusions, and the nights are restless, Qjjdema of the lungs pro- vokes incessant coughing. Swelling of the genitals is often painful, but does not noticeably interfere with urination. Death may ensue suddenly from urse- mic convulsions when danger is least expected. Ashby attempts — and it seems wisely to the writer — to differentiate between septic and post-scarlatinal nephri- tis, either of which may be met with during the course of scarlet fever. The urine in the first contains no blood-corpuscles, but is highly albuminous, and is not attended with dropsy nor urgemic convulsions. Autopsy in these cases shows a distinctly softened, pysemic kidney, which contains minute abscesses, and is mottled in its cortex with injected blood-vessels and inspissated pus. Death occurs from pyaemia, and not directly from the kidney lesions, which are onlv a part of the more general process. In the second class of cases death results from uraemia. The lesions of the post-scarlatinal kidney have been fully described under Pathology. Sequelae. — Chronic nasal catarrh, ozsena, pharyngitis, or hypertrophy of the tonsils, with acute attacks of quinsy, or suppurative otitis, wdth chronic otorrhoea and deafness, more or less complete, are among the dreaded reminders left after scarlatina, especially where the angina has been malignant. In many such cases the tonsils become deeply excavated, and the soft palate sloughs ; but even under these circumstances recovery is possible. Or, as has previously been noted, diphtheritic-like membrane may cover the fauces, palate, and even spread on to the epiglottis and into the larynx. Death from exhaustion or hseniorrhage usually terminates such cases, or, if life is for a while prolonged, death comes later from septicaemia, often terminated by septic pneumonia (seventh to four- teenth day). But even septic pneumonia is not necessarily fatal, for recovery took place in one of the writer's cases after the appearance of this sequel sub- sequent to otorrhoea and cervical abscesses and sloughing. The amount of damage sometimes inflicted by these cervical sloughs is frightful. Smith speaks of one which laid bare the carotid and produced death by its per- foration. Williams relates a still more remai'kable case, in which superficial ulceration of the fauces, palate, and tongue Avas conjoined with suppuration of the lymphatics of the neck. This was followed by sloughing, exposing, in the triangle of the neck, a space bounded by the edge of the sterno-mastoid, the upper border of the thyroid cartilage, and the median line of the neck. Never- theless, under antiseptic treatment, the boy made a good recovery, although he was only six years of age and had previously been considered delicate. Broncho-pneumonia^ pleuro-pneumonia, empyema, and peritonitis are among SCARLET FEVER. 167 the possible complications of scarlatinal nephritis. If the temperature runs high, the tongue becomes dry and brown, the urine scanty and albuminous, and death rapidly ensues. But milder cases are not hopeless if the urinary secretion can be re-established. Qardiac dilatation, endocarditis, and pericarditis are the more frequent heart-lesions that should be guarded against in every scarlatinal nephritis, for, conjoined with increased arterial tension and general malnutrition, they may bring sudden death either from heart failure or embolism. The possibility of such untoward termination to nephritis should never be forgotten, for no sharper reproach can come to the physician than the thought that had he allowed less work to be thrown upon a weakened heart he might have carried his patient into safe convalescence. Otitis, with perforation of the membrane, more than any other sequela, has too often been left a lifelong reminder of scarlet fever. In many of these cases little pain is complained of, although the fever remains suspiciously high until a purulent discharge from the ear makes its appearance. Mastoiditis or purulent meningitis may prove fatal, but in a majority of these cases no such complications take place, and the child recovers, more or less deaf or afflicted with a chronic otorrhoea. According to Batut, statistics in Belgium show that out of 1892 cases of deafness, 216 followed scarlet fever. Another observer found out of 400 cases 144 due to the same cause. Synovitis has already been referred to under the head of Arthritis, as liable to occur about the second week. Suppuration and pyaemia are the chief dangers in these cases. Cerebral lesions, such as paralyses, blindness, aphasia, loss of memory, hemiplegia, etc., are among the sad sequelae of the urgemic convulsions of scarlatinal nephritis. Convalescence from severe cases of scarlatina is always protracted, the subsequent aneemia lasting for months or years, especially in scrofulous chil- dren, in whom the virulence of the poison is most lasting in its effects. Many of the most discouraging cases that come into the hands of the physician deal- ing largely with the diseases of children are those in which the child's vitality has been undermined by malignant scarlatina. Such children frequently suffer for years from the so-called mucous disease of Eustace Smith or from renal incompetence. In other cases there is a chronic otorrhoea or offensive ozEena, which renders their lives miserable, and so saps their vitality that they succumb easily to intercurrent disease. This is especially true of those chil- dren in whom the functions of the kidneys have been seriously crippled by post-scarlatinal nephritis. Such a previous history always awakens serious apprehensions in the presence of diphtheria, typhoid, or any septic disease. Diagnosis. — The early diagnosis of a mild case of scarlet fever is often a matter of great difficulty, but it is a matter of no little importance to the patient, for such mild cases seem to be the ones most liable to nephritic com- plications. Since mild cases may communicate dangerous attacks to those more susceptible, it is always safe to give the w^ell children the benefit of your doubt by isolating all suspicious cases. Nausea, pain in swallowing, and fever constitute a trio of symptoms sufficient to isolate a patient until a rash of some kind appears. This may be so light and transient, especially if there be coin- cident diarrhoea, that it may escape detection unless carefully watched for ; and even then there is an erythema scarlatiniforme that without previous history may deceive the very elect in paediatrics. In such cases, however, the throat does not show the characteristic stippling of scarlet fever, and a brisk emetic or purge brings the case to a speedy termination. The early differentiation of 168 A3IERICAN TEXT-BOOK OF DISEASES OF CHILDREN. rubella from scarlatina is often puzzling, but Jamieson calls attention to the fact that in rubella the characteristic tongue of scarlet fever is absent, Avhile tlie mild catarrhal symptoms of the former are not ordinarily present in the latter disease. The eruption of measles is most distinctly patchy, and is preceded by several days of drowsiness and the symptoms of an ordinary cold. But in all doubtful cases isolate and "wait for light, remembering " that nephritis occur- ring after an anomalous rash makes it practically certain the jorimary attack was scarlet fever." Broncho-pneumonia under similar circumstances justifies a diagnosis of measles. Prognosis in scarlet fever must be largely influenced by the character of the then prevailing epidemic and the general condition of the child. The viru- lence of the scarlatinal poison and the susceptibility of the one attacked deter- mine the degree of restlessness, jactitation, and delirium observed. Initial eclamptic attacks rarely occur, except in unusually nervous, susceptible chil- dren, and their occurrence is of very unfavorable portent. As a rule, the early and extensive implication of the cervical lymphatics is a forerunner of serious throat complications. Nasal diphtheria complicating scarlatina is of the gravest import, and the gravity is proportionate to the early age of the child, children under four years giving as high a mortality as 28 per cent. The younger the child the more guarded should be the prognosis, especially Avhen associated with diarrhoea, which is regarded by Ashby as a very serious symptom. AYhere the temperature continues high (104°-106°), and there is much diarrhoea or extreme restlessness, or the angina is malignant, the prognosis is always grave. Drowsiness is always an unfavorable symptom, and a high tem- perature continued into the second week is sufficient ground for anxiety. Desquamation is seldom completed before the sixth week, and is not always at an end in twice that time, Finlayson fixing the infective period of this disease as seven to eight weeks. The nephritis complicating or following scarlet fever is more dangerous than the primary disease. Where persistent vomiting occurs, not only on the first, but on subsequent days, the prognosis is correspondingly grave. Post-scarlatinal nephritis is the most favorable form of parenchymatous in- flammation of the kidneys, usually ending in recovery in two or three Aveeks by means of copious diuresis, but it is worth remembering that the excessive excre- tion of uric acid, which persists well into convalescence, may form gravel or calculi. As a rule, epithelial casts and detritus persist after the disappear- ance of the albuminuria, sometimes for an exceedingly long time, especially in cachectic children. Death rarely occurs before the fourth day, and usually not later than the seventh, except from post-scarlatinal nephritis. Sudden death may result from rapid and uncontrollable increase of dropsy, either into the peritoneum, pleura, pericardium, or ventricles of the brain, or from oedema of the lungs or glottis. Or, stopping short of immediately fatal results from oedema, the end may come more slowly from inflammation of the lungs or pericardium, or still more slowly from gangrene of the genitals or from bed-sores. Or, as may be inferred from the above, the nephritis may assume a chronic form. The relation between the intensity of the scarlatinal eruption and the dan- ger of subsequent nephritis is by no means constant, although the writer has come to dread its appearance in the lighter cases because these are the ones in which the care of the parents is apt to be relaxed with the apparent rapid con- valescence of the child. SCARLET FEVER. 169 Sej-'ious cerebral affections, such as paralysis, blindness, aj^hasia, loss of memory, hemiplegia, may remain as sequeliTe of scarlatina. Mortality varies "widely with the epidemic. That in the Manchester Chil- dren's Hospital varied from 6 to 25 per cent, according to the epidemic, the average for ten years (1877—87) being 11.8 per cent. Of 10,000 cases reported by Collie, the mortality was 12.5 per cent, for all ages, that between three and four years reaching as high as 25 per cent. These figures, it must be confessed, are too high for the average American practitioner, but he may, like foreign physicians, be compelled to radically change his ideas on the subject. Brettonneau, for instance, up to 1799 thought scarlatina the mildest of all the exanthemata ; and so also the Irish physicians thought from 1804 to 1831. But Brettonneau was obliged to entirely change his views after encountering the fatal epidemic at Tours in 1824 ; and a similar outbreak in Dublin in 1881 completely revolutionized the views of the Irish physicians in regard to the fatality of scarlet fever. Treatment. — A hopeful fact, always to be borne in mind in any choice of treatment adopted in scarlatina, is that it is a self-limited disease, and that no remedy has yet been discovered that will either abort or greatly modify its course. The medical literature of the past twenty-five years teems with alleged specifics, but all of these by subsequent trials have been found no better nor worse than those proposed before them. Nevertheless, the intelligent physi- cian owes it to himself and his patients that he shall not desert them upon the rocks of medical agnosticism nor wreck them upon the snags of polypharmacy. If he cannot abort the disease, he may make its course less uncomfortable to his patient, and by careful foresight ward off many a threatening complication. Diet is not unimportant in scarlet fever, for our aim from the very begin- ning should be to tax the kidneys, already in a catarrhal condition, as little as possible with nitrogenous materials. Hence the ideal food for the scarlet-fever patient is koumyss, skimmed milk, or milk and Vichy. But the ordinary American child will not long tolerate such light diet, especially when rapidly convalescing, so we are usually forced to add to our diet-list broths, soups, light puddings, and baked apples, happy if thereby we reduce meats to a minimum. While the writer cannot agree with Jaccoud that a milk diet is an absolute safeguard against post-scarlatinal nephritis, it is true that a liquid diet and warmth should be carefully secured for at least four weeks. Gexeral Treatment. — If the initial nausea is vexatious, it may often be allayed by: I^. Aquse cinnamomi Liquor calcis da fsj. Tinct. gelsemii f^ss. — M. Sig. Teaspoonful every hour. For the high arterial tension and fever, tincture of aconite, given according to the plan of Ringer — i. e. a drop every quarter hour until arterial tension is decreased, and then given sufficiently to hold the pulse at that point every two or three hours — is very satisfactory. Chloral hydrate is a favorite with the writer, almost entirely displacing the tinct. ferri chloridi of his earlier practice, except in those cases where there is malignant angina from the beginning. In such cases nothing has been found superior to the tincture of the chloride of iron (one drop per dose for each year of the child's age), with whiskey or brandy, given according to Dr. Chap- man's plan. The surprising tolerance of such children for alcoholic stimulants 170 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. shows that their power is expended otherwise than in their usual effects upon the brain. Many such children Avill take f sss of brandy every hour without showing any of the usual physiological effects. In ordinary cases, however, small doses of chloral hydrate seem to be all that is necessary to relieve rest- lessness, moderate the angina, and, to a limited degree, act as an antiseptic. For the first forty-eight hours such a prescription as the folloAving has often proven most useful : Ki. Chloral hydrate 3ss-j. Camphor water f Iss. Syrup of orange-peel f §iss. — M. Sig. To alternate with aconite as required. When the eruption is tardy in appearing, a hot salt or mustard bath will expedite matters, or, if these are ineffectual, packing in a sheet wrung out of hot water and sprinkled with mustard rarely fails. The throat is too often neglected, and yet here is the focus from which spread many of the dangerous complications of this disease. Local antiseptics may be a modern device, but Underwood came very near to the writer's ideas when he wrote on this subject many years ago : " The throat must be often syringed with .... though the quality is perhaps of far less importance than its being frequently made use of, which is absolutely necessary, especially in young children Even syringing the throat with hot Avater is found to administer immediate relief." The local treatment of the throat with peroxide of hydrogen spray, as directed under the head of Prophylaxis, can hardly begin too early, and the same may be said of the inunction of the body with some antiseptic ointment. Quinine internally may be added later if there is evidence of failing strength. Cerebral symptoms, unless associated with scanty urine, may be rendered tolerable by the addition of bromide of potassium (grs. v-x) to each dose of the chloral hydrate mixture, with a mercurial purge and the application of cold to the head. Phenacetin is sometimes a great comfort in such cases, but the writer discourages the use of the other antipyretics in scarlet fever, except as a last resort in abnormally high temperature. Even in these cases persistent sponging Avith cool water, or even cold affusion, ought first to be tried. Per- sistent drowsiness always awakes suspicion as to post-nasal complications, and emphasizes the necessity of nasal irrigation, frequently repeated. Scarlatinal arthritis in cachectic children may proceed to suppuration and destruction of the joints, but, fortunateh', most of these cases are more pain- ful than dangerous, and yield promptly, like true rheumatism, to fair doses of salicin and codeine and wrapping the affected joints liberally with cotton batting. Cervical adenitis is more frequently overtreated than neglected, for the swollen and tender glands apparently require immediate attention. And yet the trouble lies farther back, for the debris that blocks these inflamed glands comes usually from the pharynx. Hence efficient pharyngeal and nasal cleans- ing Avill do more for adenitis than poultices, lotions, or ointments. So-called energetic treatment too often precipitates the very troubles we are seeking to guard against. Instead of poultices and iodine, simple rest and warmth will often work wonders even in brawny, swollen necks where suppuration appears inevitable. At all events, camphorated oil, applied on absorbent cotton, should be tried before proceeding to more vigorous measures. Diarrhoea is apt to be quite persistent, and occasionally painful, when once SCARLET FEVER. 171 it makes its appearance. So far, I have rarely seen it assume a dangerous aspect, for it usually can be held in check with paregoric alone or conjoined with bismuth in an emulsion. ScARLATiN^AL NEPHRITIS. — Individuals and epidemics of scarlet fever vary so greatly in their liability to nephritis that it is difficult to rightly estimate its prophylactic treatment. From 60 to 70 is given by various authors as the average percentage in dangerous epidemics, and from this it falls to 6 or 7 per cent, in ordinary cases. The writer believes that this latter proportion can be still further reduced by the proper care of children in the mildest form of the disease, for these are the very ones which give us the highest proportion of fatal cases of nephritis. It follows, then, that all children ill Avith scarlet fever should be kept in bed during the rash, no matter how mild it may be; and, furthermore, such children should be confined to warm rooms, or, better still, to bed, for four or six weeks from the appearance of the initial symptoms. At least twice a week during this time the urine should be examined, and upon the appearance of the slightest unfavorable symptom the child should be sent back to bed again if he has already been allowed to be about the room. But should these premonitory symptoms be disregarded, or if, in spite of these precautions, scanty albuminous urine and dropsical effusions appear, then the physician's most energetic efforts must be directed toward making the skin or intestines temporarily assume, as far as possible, the functions of the kid- neys, throwing on the latter, at the same time, as little work as possible in the way of the excretion of nitrogenous refuse. (See Diet.) The copious use of water, if tolerated by the stomach, Avill act as one of the very best of the diuretics. Long ago Roberts placed pure spring water at the head of the list, and the writer has not yet found any diuretic to displace it, though lemon- juice, raspberry vinegar, or skimmed milk may be added without harm to induce the child to drink more freely of the water. Should the urine still remain scanty, then diaplioresis must be induced in order to increase the action of the skin — first, by means of baths, and then, if necessary, by drugs. A warm bath (98°-100° F.) for fifteen to twenty minutes is often grateful to the child, and, if supplemented by a flannel pack, is very efficient. The hot-air or steam bath, as described under the treatment of Acute Nephritis, may likewise be employed with success. Any of these methods will be assisted by the internal use of diaphoretics, chief of which are the preparations of jaborandi. Sips of a hot infusion of the leaves (3j to Oj) act both as a powerful diaphoretic and sialagogue. To avoid the latter action Smith prefers the alkaloid pilocarpine, ^ to 2V grain, conjoined with an alcoholic stimulant every four to six hours. Should this fail, the same writer speaks highly of the following prescription : I^. Potassii acetatis Potassii bicarbonatis Potassii citratis aa 3ij . Infus. tritici repentis fiviij. — M. Sig. Teaspoonful every three or four hours to a child of five years. More palatable and fairly efficient is the following : ^. Liq. ammonii acetatis Syr. acidi citrici da f^ij. — M. Sig. Teaspoonful every hour in hot lemonade. 172 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Or, where there is considerable dropsical effusion, this can be with advantage alternated with diuretin (gr. j-iv), given in a large amount of water. Dropsy usually requires, in addition, the free use of some hydragogue cathar- tic, of which the compound jalap powder (gr. v-x) is certainly the most efficient and unpleasant. Hence, when it is found impracticable to repeat the dose as often as required, it may be supplemented by a cream -of-tartar lemonade, made by dissolving a tablespoonful of the salt in hot water, diluting with an equal amount of cold, sweetening to taste, and adding sufficient claret or port to make agreeable. Most children will take this laxative readily. Or the following prescription of J. Lewis Smith may be employed : !^. 01. cinnamomi gtt. viij. Magnesii sulphatis 5J- Potassii bitartratis oij. — M. Sig. One teaspoonful repeated from two to four hours, until catharsis occurs. But the use of laxatives should be continued no longer than is strictly necessary, for their repetition brings angemia, a result greatly to be deplored. After relieving the initial congestion of the kidneys, stimulating diuretics are helpful; and of these digitalis has justly a high reputation. The infusion is a reliable preparation, and may be given in connection with acetate of potas- sium, as in the following mixture: I^. Potassii acetatis ^ss. Infus. digitalis f^vj. — M. Sig. One teaspoonful every four hours. Local treatment will also greatly help in relieving the fever and backache. Foreign writers speak highly of the use of leeches over the kidneys in these cases, but the majority of American physicians are willing to rely upon the use of poultices or plasters. A large warm flaxseed poultice, containing mustard or digitalis, often acts like a charm. Smith prefers one made of 1 part each of powdered mustard and ginger to 16 of ground flaxseed, and advises dry cupping when the child is not frightened thereby. Sluggish kidneys may be gently stimulated by capcine plasters or some mildly stimulating embrocation, and a flannel bandage worn day and night. It ought never to be forgotten that while the liability to heart failure is not as great in scarlatinal nephritis as it is in the convalescence of diphtheria, yet it is a possible danger, and one from which death may rapidly occur. An irregular, flickering pulse requires absolute confinement to bed and the con- tinued use of some chalybeate tonic. A pleasant one may be found in the following : ^.

Nitro-glycerine tablets (yot g'"-) SCABLET FEVEB. 173 are very valuable for temporary stimulation of the heart, and may be used hypo- dermatically if the need be pressing. Prophylaxis. — All attempts to procure personal immunity by means of inoculation have up to the present time proved ineffectual. The same may be said of prophylactic medicaments, for it is more than doubtful whether any known drug has the power to prevent the occurrence, or to greatly modify the course of, scarlet fever after its incubation. Even Hahnemann's vaunted specific, belladonna, has failed so often and completely that it need only be mentioned as one of the curious delusions .of medical history. The same may be said of sulphocarbolate of soda (Beebe's), quinine, salicylate of sodium, and the other alleged preventives which from time to time appear and dis- appear in medical literature. The fact is that epidemics of scarlatina vary widely in their intensity and danger. Hence it is that in one epidemic the liability to contagion is reduced to a minimum, and whatever may be used at that time receives credit for prophylactic poAvers which fail miserably when next put to the test. Our efforts must, therefore, be confined to isolation of the patient and disinfection of whatever touches or comes from him, for it must be remembered that not only the desquamatory scales, but also blood, serum, breath, urine, and fijeces probably carry infection during the entire course of the disease. Now, as every case of scarlatina, even the mildest, may communicate a dangerous form of the disease, it is always wisest that every case should be treated as if it might develop a most dangerous epidemic. Six weeks of quar- antine are none too long for an average case of scarlatina, and this should be indefinitely extended as long as desquamation may require. Seven years' experience in one of the orphan asylums of Chicago has convinced the writer that this is not only theoretically possible, but actually does prevent the spread of the disease, for never during these years has there been a general epidemic of scarlatina in the asylum, although sporadic cases have been not infrequent. In such institutions isolation can be more effectually carried out than in private families, but the effort should be made, and is usually attended with the hap- piest results. Long ago Dr. Budd wrote in reference to scarlatina : " Time after time have I treated this fever in houses crowded from attic to basement with children, who have nevertheless escaped infection by the simple method of isolation." Reliable statistics show that 50 per cent, of the children thus protected escape infection, and still better results ought to be obtained by local and pei"sonal disinfection added to isolation. Disinfection of the sick-room should never be omitted. For this purpose J. Lewis Smith highly recommends volatilization of the following mixture in boiling water: ^. Acidi carbolici 01. eucalypti da fij. 01. terebinthinae f§vj. — M. Sig. A tablespoonful to be added from time to time to a pan of hot water, to be kept boiling on a gas stove or grate fire. The sick-room should be the largest, most sunshiny, best-ventilated room in the house, and, if possible, should have an open fireplace. All curtains, pictures, ornaments, and furniture not absolutely necessary for the comfort of the patient should be removed before the child is placed there, and no one but the nurse and physician allowed to enter. The nurse should wear a loose wrapper and cap, to be dropped inside the door should she be compelled to meet other persons for any purpose outside the door. 174 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. An ordinary bed-slieet, tacked by one edge over the door and kept moist- ened with a 2 per cent, solution of carbolic acid, has apparently been helpful in preventing the spread of the disease in asylum practice, Avhere, the writer agrees with J. Lewis Smith, the "area of contagiousness is small, and hence the disease is more easily quarantined than either measles or pertussis." For disinfection of the patient J. Lewis Smith recommends as a local dis- infectant to the faucial mucous membrane corrosive sublimate, 2 grs. to a pint of water (1 drachm containing -^^ of a grain). This may be used as a gargle, or as a spray from a hard-rubber atomizer. The same solution may be em- ployed for cleansing the nasal cavities. The Avriters preference for faucial application is a solution of eucalyptol in peroxide of hydrogen (gtt. xv to f^j), used in the cup of an ordinary steam atomizer. The same solution may be applied upon a swab to the fauces if there be extensive necrosis : or, diluted with an equal amount of water, it may be used for washing out the nares with a douche or fountain syringe. Others speak highly of 50 per cent, boroglycerin for topical disinfection of the throat, and all sorts of more energetic disinfectants have been recommended (mineral acids, chlorine-water, galvano-cautery, etc.) with less obvious justifica- tion. The frequent anointing of the body Avith some form of non-irritant anti- septic ointment in order that the action of the skin may be encouraged, rest- lessness allayed, and the scattering of the scales reduced to a minimum, is strongly advised. Such an ointment as carbolic acid, grs. 20, thymol grs. 10, to vaseline and lanoline each half an ounce, may be favorably employed. This should be applied at least twice daily, the skin having been previously cleansed Avith warm water in which a little soda is dissolved. J. Lewis Smith speaks highly of the following: I^. Acid, carbolic! Olei eucalypti, ad .5j. Olei olivoe 3vij. — M. Sig. For inunction every three hours. Even the old-f:ishioned fresh lard or ham-rind will be found grateful to the patient and helpful to the health officers. An excellent and more elegant prescription is: ^. Thymol g^'- x. 01. theobromw 3j. Alcohol q. s. — M. Ft solutio. Sig. For inunction twice or three times a day. Disinfection of the room in which the patient has been is scarcely less important than that of the patient, since the virus of scarlet fever is so tenacious in its potency that it will persist for years in houses or rooms not properly disinfected. If the walls are papered, they may be rubbed, as is done by paper-cleaners, Avith slices of rye bread, Avhich aviII remove microbic spores and scales ; or, better, if possible, they should be repapered, calcimined, or whitewashed. Previous to this, sulphur— 1 lb. to each 100 cubic feet of room-space — should be burned in the infected apartment, Avhich should be kept closed for eighteen hours thereafter. The efficiency of sulphur dioxide as a disinfectant is greatly increased bv SCARLET FEVER. 175 combining with it the vapor of water in a hermetically closed room (Squibb). Hence the room should be closed as tightly as possible by pasting strips of paper over the door-jambs and keyholes before burning the sulphur candles. To increase the efficiency of the sulphur dioxide by its union with aqueous vapor, the candles may be placed on bricks in an ordinary wash-tub partially filled with water, and allowed to burn in the closed room until they go out for want of oxygen. After the room has been opened and aired as fully as possible, it ought never to be reoccupied until the walls have been cleaned as previously directed or thoroughly scrubbed. All sheets, bedding, towels, and articles that can be washed should be im- mediately thrown into boiling water after being used, and those articles that cannot be washed or boiled should be fumigated with sulphur, baked, or, still better, destroyed by burning, as should all toys and books used during the convalescence of the patient. RUBELLA. By WILLIAM T. PLANT, M.D., Syracuse. Perhaps there is no other disease of brief duration and benign character that has been so much written about and so variously named as rubella. It was for so long held to be related to measles or scarlet fever, or both, that the following names have naturally come from such views of its nature : French and Ger- man measles or scarlet fever ; false, bastard, and hybrid measles ; and epidemic roseola. These and others not worth remembering have come down to us. The German name, Rbtheln, is not, and will scarcely become, popular in America, because of its foreign appearance and difficult pronunciation. More attractive and satisfactory than all other names, and now quite generally adopt- ed by English-speaking people, is that of I'uhella — a diminutive of rubeola, first suggested by Veale not many years ago. Indeed, the disease seems to have been waiting for a name, and only lately to have found a fitting one. Previous to the middle of the last century rubella had had no very clear description or decided differentiation from measles, and almost down to the pres- ent time very many in the profession have regarded it as a sort of modified or mongrel measles. Now, however, through a happy agreement of medical opin- ion, the following points may be regarded as settled : 1st. Rubella, though much resembling measles and somewhat resembling scarlet fever, is a distinct entity, independent of these as of other diseases. 2d. It confers no protection against measles or scarlet fever, nor can either of these affections influence or prevent an attack of rubella. Rubella is an acute, contagious, eruptive disorder, which runs its course quickly and terminates in recovery. It occurs, with few if any exceptions, but once in a lifetime. It commonly occurs in epidemics of rather limited extent, though sometimes it spreads over large tracts of country in a short time ; and not infrequently the observant physician encounters sporadic cases whose origin he cannot make out. At times it appears to part with its tend- ency to spread, though probably at all times its contagious property is less pronounced than that of measles. All ages are liable to it, adults nearly or quite as much so as children. Its incubation seems not to be definitely known, or perhaps the time is not fixed, but variable. Writers state it as from one to three weeks. Symptoms. — The disease begins rather abruptly. When it follows its typical coui'se there are at first shiverings, feverishness, aching of head, back, and limbs, loss of appetite, and sore throat. These prodromal symptoms sel- dom last longer than twenty-four hours before the eruption appears. It is to be remembered also that in many instances — and in children, perhaps, in most instances — the eruption appears as the initial symptom, without previous chilli- ness, fever, or pain or any complaint whatever of illness. When there is fever, it often subsides almost completely within one day after the coming out of 176 RUBELLA. 177 the eruption. Indeed, the aifection is not attended at any part of its course by much rise of temperature — seldom more than three degrees and often less than one degree. The eruption, first observed on the forehead and face, extends; rapidly over the neck, trunk, and limbs. The rash is papular, and the papules vary in size ; the average is rather smaller than the eruption of measles ; dots and points are interspersed with blotches the size of lentils or small split peas. The eruption is slightly raised above the surface, like that of measles, and is red in color, rather brighter than that of rubeola. In some instances it is sparse and rather pale ; in others high-colored — rose-red — and so abundant that some of the papules touch at their edges and form blotches of consider- able size. These never arrange themselves crescentically, as the eruption of rubeola so frequently does. It should be remembered that the eruption of rubella is multiform ; sometimes it is punctated, and so fine as to resemble scarlatina more than rubeola. The duration of the eruption is variable, the average being probably between three and five days. Often it wholly disap- pears within three days. When the rash is abundant and high-colored, it is apt to remain rather longer, and in such cases intense itching may be a prom- inent feature. The eruption is seldom followed by desquamation except of a very light, branny character. Sore throat is an almost constant symptom in rubella, and appears early. The pharynx is inflamed and the tonsils are red and swollen, and there is more or less pain in swallowing. This angina is usually slight, and subsides quickly, often to recur in the last stage of the disease. This secondary sore throat, when present, according to Eustace Smith, is extremely characteristic of rubella. . There is, besides, a characteristic enlargement of the superficial cervical and posterior auricular glands. Almost all writers have alluded to this symptom : it is so generally present that it may be regarded as diagnostic. Griffith, however, believes that this glandular swelling, while a very constant symptom of rubella, is probably nearly equally as frequent in rubeola, and that it is by no means of as great diagnostic importance as is usually supposed. In some cases many glands about the neck are enlarged, in others only one or two. There is also, in many cases of rubella, a slight coryza and some con- junctival congestion. Diagnosis. — Except that rubella, as a late author says, may be " mis- taken for some of the anomalous erythematous or roseolous rashes" that children sometimes have, there is no danger of its being confounded with any- thing else but mild measles, or, possibly, with scarlet fever. Perhaps the patient has already had these diseases ; in that case he is little liable to them again. Perhaps rubella is prevalent ; if so, the chances are in- its favor. The prodromal stage in rubella, if present at all, is very short ; the fever short and often absent ; the tight, resonant, bronchial cough, so constantly present during measles as to make a part of its history, does not belong to rubella. The eruption is smaller, more multiform, and lighter in color than that of rubeola, and is never, like it, concentrically grouped. The sore throat and swollen cervical, post-auricular, and submaxillary glands that are all but constantly present in rubella do not belong to measles ; nor is its rash so scarlet or finely punctated as that of scarlet fever. It frequently happens that rubella resembles scarlet fever more than measles. In this case there is a diffuse red rash and some faucial inflammation. The rash, however, is not punctiform as in scarlatina, but erythematous in character, and in certain localities, particularly the neck and the dorsum of the hands and feet, it is papular, or at the least rough. The diff"erentiation is most troublesome when the eruption is declining. 178 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Treatment. — Probably no disease needs less medical treatment. Its own direction being toAvard recovery, it may generally be safely left to follow it. The patient should be sent to bed, as well for the safety of others as for his own. As there is conjunctival irritation in most cases, the room should be darkened. The diet should be light and bland, as toast, with hot bread, milk, and various broths. Cool water should not be denied. If itching be trouble- some, it may be allayed by frequent tepid bathing. Treat headaches by apply- ing cloths wrung from cold lotions, or by hot foot-baths made more eifective by mustard. The sore throat is well treated by the steam atomizer or by gargles, as fol- lows: !^. Potassii chloratis 3iss. Glycerini fsiij- Tinct. ferri chlorid f ^ss. Aquse q. s. ad fjviij. — M. Sig.

Varicella, or chicken-pox, the lightest of the exanthemata and the most trivial of diseases, was first described as a distinct affection a few years before the close of the seventeenth century. There can be no doubt that it had existed from a period far remote, but it was not until then differentiated from srnall-pox and other eruptive disorders. Dr. William Heberden, an English physician who lived between 1710 and 1801, was the first to give a full and accurate description of this disease, though several writers before his day had described it less perfectly, and one of them. Dr. Richard Morton, gave it its earliest and best name of chicken-pox. It is an infectious, acute, and transient affection, runs a definite course, and, with very few, if any, exceptions, occurs but once in the same person. Though it bears some resemblance to the lighter forms of variola, it has no real relation to this disease, as has been abundantly proven by the observations of two centuries. Therefore, the name varicella, conferred upon it by Vogel in 1764, is founded upon error and is misleading. It is essentially a pediatric disorder, as it only affects infants and young children — at least the writer does not remember to have met with it more than once or tAvice in adults. It may be regarded as quite a I'are affection after four- teen or fifteen years of age. It travels in epidemics, often widespread, regard- less of season, race, country, or climate, and of everything but age. Incubation. — The incubative period is rather long. Henoch fixes the duration of this period at 12 to 13 days; Gerhardt, 14 to 15; Eichhorst, 13 to 16 ; and Strlimpell, 13 to 17. In cases of the inoculated disease d'Heilly has observed as short an incubation as 3 days ; but with the affection as ordi- narily contracted this period of latency may be assigned between the lowest and highest figures given by the authorities quoted. Symptoms. — At the close of the incubation the active period of the disease is often ushered in with a little chilliness, aching of head and limbs, diminution of appetite or complete anorexia, and perhaps nausea. With these symptoms there is usually moderate fever — from 99° to 102°. It often hap- pens, however, that the eruption is the first symptom noticed, no complaint of illness having been previously made by the child. Only in rare instances are the phenomena of invasion alarming or even severe. Decided chills, fever of high grade, and even delirium, are occasionally met with at the onset, and in one case under the writer's care the disease was ushered in by two severe con- vulsions. Some authors allude to this very rare mode of beginning. But, whether these first symptoms of invasion are usually mild or entirely unnoticed or exceptionally severe, they are of short duration, and the eruptive stage is soon established. As it first appears, irregularly scattered over the body, the eruption consists of some small rose-red papules which very quickly 179 180 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. develop into vesicles. This change is effected so quickly that very often the papular stage is over and the vesicular stage is well under way before the eruption is discovered. The vesicles are seldom either numerous or large. Varying in number from a dozen or two to a hundred or more, they are scat- tered rather irregularly over the trunk, limbs, and scalp. They seldom make very much show on the face. Frequently a few are found on the forehead and temples when all other parts of the face are quite free. Often, if searched for, some blebs may be found upon the mucous membrane of the mouth and fauces. When seated thus on a mucous surface they quickly rupture and leave small ulcers. The vesicles of chicken-pox are quite variable in size : some are not larger than pin-heads, while others reach the size of small peas. It was presumably the resemblance in average size to the "chick-pea," or "cicer," of Southern Europe that suggested to Dr. Morton the name of chicken-pox. The tegumentary covering of the vesicle is very thin, being composed only of the outer layers of the skin. It contains an alkaline serum of crystal trans- parency, whence another admirable name for the affection, '■'■ crt/stalli," and the German " Wasserpocken.'' It was long ago aptly said that the rash of chicken- pox suggests an appearance as if scalding water had been flirted over the sur- face, each drop having raised a small transparent blister. Some of the vesicles Fig. 1. ^ IE M E ME K 1 E ME M E M C *^"' p^ 105° : , "tr Z 2 7* 49, 104^ " X ^ T ~ "^ Ji -•- ^ _ -il. .Si- X % 103° " S 1 ^ -& ■^. 5_ -f t _ __ :S-:|:-T- :f 1 — -* 5 _ ^ 102° " ^ -*- B ^ 3C fl S A J t^ -4 101° ' *> ^ 100°: 99°: Q8P: 97°: 4 r- J \l \ --.^ u 2 u % f tt B t X - £ t J / 1 i K i. t p - JL t u ■ T I J Daif ofDis. 1 2 3 4 6 6 7 MEMEMEMEMEME -| -^ i 1 1 — S- — e- ■;« — -»;■ — -§— -i- — -t ! -^ — a._^ ^ _^ -K S -^ * ^ ^ ::55 ■- - 1 n hm : E =f=r ±x ^ h S ' = 1 3 A^- h ^ E2 1 \]}\ 12 8 4 5 6 Temperature Charts of Varicella. are surrounded by a narrow, often linear, and very pink areola ; others rise abruptly from a surface of natural color. A peculiar and distinguishing feature of chicken-pox is that the eruption CHICKEN-POX. 181 comes out in successive crops. Before, or as soon as, the first vesicles have arrived at their full size others are just beginning ; and this may be repeated twice or thrice, or even four times. The varicellar vesicles never become pustular like those of small-pox unless from scratching or other irritation, neither are they partitioned or umbilicated, as are those of variola. They are very rarely so numerous as to become confluent. Another peculiarity of this disease is that, if the eruption is at all copious, many, perhaps most, of the vesicles abort and shrivel away before making much progress toward a completed development. I have observed that late vesicles are especially prone to abort. The other vesicles advance rapidly to maturity and enter on a speedy decline. Their fluid becomes opalescent and turbid, and dries down into a thin yellowish crust that soon crumbles and falls ofi", leaving a temporary redness of the skin. Now and then a few of the largest vesicles leave permanent cicatrices behind them. During the eruptive stage the fever, which is almost uniformly intermittent in type, varies in degree with the acuteness of the attack and the extent of the eruption, mild cases, with only a few vesicles, being almost apyretic ; severe cases, with a profuse eruption, being attended by a temperature of 104° or "more. The usual range and duration of elevated temperature is illustrated in the charts on the preceding page (Fig. 1). The whole course of chicken-pox seldom exceeds eight or nine days, or pos- sibly ten or twelve at the most. Diagnosis. — It is usually only to settle this important question that the physician is summoned. There can be no danger of confounding chicken-pox with any exanthem except variola. This mistake has frequently been made, sometimes with consequences deplorable to society and ruinous to professional reputation. The practitioner should therefore hold himself ready at all times to make a differential diagnosis of these affections. The following are the chief points to be attended to : Chicken-pox. Variola. Only infants and young children affected. All ages aflfected. Invasion short ; general symptoms usually Invasion three days ; general symptoms very light. severe. Eruption vesicular almost from first. Eruption ; papular stage prolonged. Eruption superficial ; never shotty. Eruption deep-seated ; hard, shotty. Seldom umbilicated. Generally umbilicated.

Eruption most on face, hands, and feet. No pustular stage. Pustular stage never alDsent. Uninfluenced by vaccination or previous Prevented by vaccination or previous small- small-pox. pox. Prognosis. — The outlook for chicken-pox is always favorable. There is no other disease that is so uniformly mild in its course and happy in its ending. There are no complications and no sequelae for the physician to guard against. Few and far-between cases are reported — mostly from Europe — in which the vesicles become large, ill-smelling, and sloughing — varicella gangrenosa. Sequelae. — It is possible to find in medical periodical literature cases reported in which an anaemic, or even tuberculous, condition has followed so closely upon chicken-pox as to suggest the relation of cause and effect ; but such instances are so very rare that Ave hazard little in predicting timely and complete recovery for all cases of varicella. Treatment. — A disease whose course and duration are fixed, and whose ending is almost always favorable, requires little aid from medicine. Beyond 182 A3IERICAN TEXT-BOOK OF DISEASES OF CHILDREN. such care as to diet and exposure as will suggest itself to any sensible physician, nurse, or mother, nothing is needed. The child should be taken from school, and should not be allowed to return until after full recovery and a thoi'ough cleansing of the body and change of clothing. All this is necessary as a protection to others. In the rare event of the gangrenous form of this disease, the importance of good ventilation, anti- septics, and plentiful stimulation must not be overlooked. If convalescence should be protracted and the child exhibit evidences of anaemia or the graver condition of tubercular disease, iron and cod-liver oil, nourishing diet, with perhaps a change of air or a short sojourn at the seaside, will be a proper addi- tion to the treatment. VARIOLA AND VARIOLOID. By C. G. JENNINGS, M. D., Detroit. Variola, or small-pox, is an acute, specific, Highly infectious disease, characterized by a typical range of temperature and a specific inflammation of the skin appearing usually on the third day of the disease as a papular eruption, which quickly becomes vesicular and finally pustular. The pustules desiccate, and leave permanent cicatrices wherever suppuration has invaded the deep tissue of the skin. Etiology. — The nature of the contagium of variola is unknown ; analogy, however, points to a micro-organism as the infectious principle. There is no evidence of the development of the disease de ?iovo, each case being transmitted from a parent case in another individual. Individuals of both sexes and of all ages, unprotected by vaccination, are subject to the disease. Even the foetus in utero does not enjoy immunity. The disease is transmitted by direct contact, through the medium of infected articles and through the air. While scarlatina, measles, and other exanthemata will infect at the distance of only a few feet, small-pox has a striking distance that is very much greater. In the Shefiield epidemic (1887) the influence of the Shefiield hospital could be traced over an area having a radius of four thousand feet. One attack, as a rule, renders an individual immune. In countries where the disease is prevalent a second attack is not uncommon. The writer saw a negro woman, ill with discrete variola, who was sadly disfigured by two previous attacks. The disease prevails most extensively among unvaccinated communi- ties. The negro race is particularly susceptible. The disease is most infective during the periods of suppuration and desiccation. Although apparently inde- pendent of climate, small-pox is a disease of the winter and spring. Pathological Anatomy. — The characteristic anatomical lesion of variola is found in the skin and mucous membranes. Small areas of congestion appear in the skin. The vessels of the corium dilate and become tortuous, and the connective tissue in the centre of the congested areas is thickened by oedema. Coagulation necrosis of the epithelial cells quickly follows, with thickening of the epidermis. These changes form the papules. Serum is poured out between the necrotic cells, and a vesicle forms. The changed cells form a meshwork in which the fiuid is enclosed. Trabeculse bind down the centre of the vesicle, while its periphery continues to distend, producing umbilication. Pus-cells form rapidly in the vesicle, and in a few hours it is transformed into a pustule. Inflammatory injection and thickening of the connective tissue surrounding the pustule now take place. If the necrotic process is confined to the superficial layers of the skin, resolution takes place without pitting. If the deep tissue is involved, a cicatrix results. Desiccation of the pustule follows, leaving a crust of dried cell-debris and pus adhering to the skin. Then the epidermis re- 183 184 A3fEBICAN TEXT-BOOK OF DISEASES OF CHILDREN. forms under the crusts, the inflammatory injection and infiltration subside, the crusts drop ofi", and resolution is complete. The process in the mucous membrane is the same. Perfect pustules, how- ever, are rarely seen, because the macerated roof yields early to the pressure, and an aphthous-looking ulcer results, often covered by a pseudo-membrane. In h^emorrhagic small-pox the pustules contain blood, and extravasations may occur in the skin and mucous membranes at any point, and in the substance of all the organs. More or less intense congestion and septic inflammation may be found in the brain, liver, lungs, kidneys, and spleen. Incubation. — The duration of the period of incubation of variola is, on the average, twelve day«. Exceptionally it may be shortened to ten or length- ened to fifteen days. When transmitted by inoculation the disease appears on the eighth day or sooner. During the period of incubation the child, as a rule, shoAYS no symptoms. Symptoms. — The clinical history of small-pox may be divided into four stages : Invasion ; eruption ; secondary fever ; desiccation or decline. The stage of invasion is ushered in abruptly. Older children complain first of chilliness, and often there is a distinct rigor. The phenomena of severe fever quickly follow. In addition to the usual symptoms of fever there are headache of unusual severity, persistent vomiting, great prostration, and severe backache. In younger children and infants the disease begins with fever, great nervous irritability, and vomiting. Very often convulsions mark the onset of the disease. They may be frequently repeated, with inter- vals of stupor or delirium. The skin is- dry or perspiring ; the tongue coated, wuth dark-red edges. The bowels may be constipated, but often a sharp diarrhoea is present during the whole of the invasion stage. Abdominal pain and tenderness are frequent. Respiration is rapid. The pulse is full and quick, ranging from 120 to 160. The temperature quickly reaches a high point, ranging from 102° to 105° F., or higher. The high temperature is maintained during the invasion stage with but slight remissions. The maxi- mum temperature of this stage is usually reached just before the appearance of the eruption. Partial paraplegia, numbness, and incontinence of urine and fseces, are sometimes seen in children. In children more frequently than in adults initial or accidental rashes appear about the second day, and cause much difficulty in diagnosis. The initial rash may be erythematous, simulating scarlatina or erysipelas ; or macular, simulating measles. It is very evanescent, and usually ushers in an attack of varioloid. A number of observers have noted that the areas of skin affected by the prodromal rash escape the variolous eruption. Petechia from one-twelfth to one-fourth of an inch in diameter are sometimes seen in this stage of the disease scattered over the lateral thoracic and lower abdominal regions. This rash is often of grave prognostic significance. The average duration of the stage of invasion is three days. In grave cases it is often shortened to two, while in varioloid it is often prolonged to four days. As a rule, the longer the incubation stage the milder will be the subsequent course of the disease. Notable exceptions to this rule are the delayed rashes of cases complicated by severe internal diseases, and, as Moore observes, of cases showing an early hgemorrhagic tendency. The Stage of Eruption. — On the third day of the disease, with the vari- ations noted above, the true rash of small-pox begins. The eruption shows first on the face, quickly extending to the scalp and neck. Exceptionally it covers the wrists early. After the face and neck, it next invades the trunk, extremi- ties, and finally the palmar and plantar surfaces, taking from twenty-four to VABIOLA AND VARIOLOID. 185 forty-eight hours to cover the cutaneous surface. Rarely, in very vouno- infants, the rash appears first about the lower part of the abdomen and on the inside of the thighs. Other exceptions to the usual sequence are sometimes met. The rash is most abundant on the face and on the back of the hands. It shows early and abundantly on irritated areas of skin. The eruption begins as small, slightly raised, pale-red macules, and passes through four stages of development — viz. macules, 'papules, vesicles, and pustules. The macules in a few hours become fine, conical papules, pin-head in size and larger. The papular stage continues for two days. The well- developed papules are hard and shotty to the sense of touch, " feeling like grains of shot underneath the skin." Gradual augmentation in the size of the papules takes place. On the third day a minute vesicle appears at the apex of the older papules ; it rapidly grows, and transforms the papule into an umbili- cated vesicle with cloudy contents. By the fifth day of the rash the fluid in the vesicles becomes turbid, and by the sixth day it is distinctly purulent. The eruption has now reached the pustule stage, or stage of maturation. The mature pock is globular and about the size of a pea. The increase of the con- tents has distended the chamber and removed the umbilication. The pustule is, in fact, a small abscess. It is usually surrounded by a swollen, red, inflam- matory zone, the halo of the pustule. Synchronous with the development of the cutaneous eruption a true vario- lous exanthem appears upon the mucous membranes. The visible mucous membranes are nearly always affected, and, in severe cases, the rash extends throughout the whole alimentary and respiratory tracts. The urethra, vagina, and conjunctivae are often invaded. With the appearance of the eruption a remarkable amelioration in all the symptoms takes place. The temperature rapidly falls, often reaching the normal point or a little above on the fifth or sixth day. This fall of the tem- perature is pathognomonic of the disease. The pulse loses its rapidity and the gastric and intestinal irritability subsides. In cases of severity the remis- sion is less marked, and the severe symptoms of the incubation stage persist with but little relief. In discrete small-pox convalescence often sets in after three or four days of the mild febrile movement which follows the sharp decline of the beginning of the eruptive period. In children, with the beginning of the vesicular stage the eruption in the mouth and throat becomes a source of distress and danger. The vesicles rup- ture, and a streptococcus ' pseudo-membrane covers the resulting erosions and often extends over a large area of mucous membrane. Nasal and pharyngeal obstruction results, with distressing symptoms, and if the larynx be invaded, croup with dangerous stenosis may supervene. In typical variola the maturation of the rash is accompanied by the onset of the secondary fever or fever of suppuration, which is of indefinite duration and varies in intensity with the severity of the attack. The child becomes restless and there is mild or active delirium. The temperature ranges from 101° to 104° F., with morning remissions and evening exacerbations. The pulse is quick and hard. Often the symptoms assume the typhoid type, with low delirium or stupor, a rapid, feeble pulse, and subsultus tendinum. A tem- perature that frequently rises above 104° during the stage of suppuration is of grave significance. (See Fig. 1). The stage of desiccation or decline begins on the twelfth or thirteenth day of the disease. The pustules begin to dry up, the inflammation and swelling of the skin subsides, the temperature gradually falls, and there is a general improvement in all the symptoms. Many of the pustules rupture and the 186 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. exuded contents form discrete or coalesced crusts. Cicatrization goes on under- neath the crusts, and they finally drop off, leaving dark, violaceous blotches that Fig. 1. Temperature Chart of Variola of Moderate Severity. are gradually changed to white, irregular, depressed cicatrices. The whole course of the disease occupies from three to five weeks. Based upon the distribution and amount of the rash, variola is classified into — (1) Discrete variola^ in which the rash is scanty and the individual lesions are more or less separated from one another by healthy skin. The disease is rarely dangerous to life, its symptoms are mild, and its course is often interrupted before the development of the pustular stage. The secondary fever is absent or of short duration. (2) Confluent variola, which is marked by an eruption that covers almost the entire cutaneous surface and invades the mucous membranes with great severity. The pustules upon the hands and face "run together, so that the epidermis is raised by a milky, sero-purulent secretion;" on other parts of the body the eruption is more or less discrete. The invasion stage is severe, and the rash appears as early as the second day. Severe vomiting and diarrhoea, stomatitis, salivation, pseudo-diphtheria, great and painful swelling of the face, hands, and feet, pygemic abscesses, high fever, violent delirium, and great pros- tration are marked features of this type of the disease. The mortality is great, and convalescence is very sIoav and often interrupted by serious sequelae. In addition to these chief varieties we recognize — - (3) Hcemorrhagie variola, a malignant form of the disease, characterized by profound alterations of the blood, leading to the formation of petechial blotches and ecchymoses and more or less profuse haemorrhages from the mucous membranes. VAUIOLA AND VARIOLOID. 187 (4) Varioloid is variola modified in its course, duration, or intensity by vaccination, previous attacks of variola, or inherited insusceptibility. The invasion stage of varioloid is more irregular in duration than that of unmodi- fied variola, and the symptoms may be so mild as to escape observation, or so intense as to simulate the onset of grave variola. Three types of variation in the clinical history of varioloid may be distinguished : (a) After an invasion stage of the severity of typical variola a copious eruption appears. With the appearance of the rash, however, a rapid defervescence begins, and the eruption is aborted in the papular or the vesicular stage. If it go on to the pustular stage, the pustules quickly run their course without causing much discomfort to the patient, and leave only faint cicatrices or none at all. Or, (h) the dis- ease runs a course typical in all respects, but the pustules are few in number and the accompanying symptoms very mild. Again, (e) the symptoms of inva- sion are well marked. A trifling eruption of maculo-papules appears and quickly fades. Instead of rapidly convalescing, however, the patient shows a period of anaemia and mental and physical prostration out of all proportion to the preceding symptoms. Complications and Sequelae. — The complications of variola are few in number. Streptococcus invasion of the subcutaneous connective tissue may give rise to multiple abscesses, phlegmonous erysipelas, boils, and, rarely, in scrofulous children, to gangrene; the deeper structures, the joints, and the vis- cera may also be invaded. In children the most frequent complications are inflammations of the mucous membranes. Pseudo-diphtheria of the pharynx, nose, and larynx is frequent in severe variola; rarely the membrane invades the bronchi. Bronchitis and broncho-pneumonia, pleuritis with resulting em- pyema, purulent otitis media, and pericarditis or endocarditis often occur. Conjunctivitis is present in all bad cases; sometimes the inflammation is very severe, and results in ulceration of the cornea and destruction of the eye. Enterocolitis is often the cause of death in infants. Diagnosis. — Typical variola in the eruptive stage presents no difficulty of diagnosis. Mild and atypical cases, however, are often very perplexing. The invasion stage may be mistaken for a continued fever or pneumonia. The sharp pain in the back, the vomiting, and the marked nervous symptoms should put the physician on his guard. The initial erythematous rash, coming on the second day, and the vomiting, are very like scarlatina. The small, often irregular, and very rapid pulse, the peculiar tongue, and the pharyngitis are distinctive of scarlatina. The rash of scarlatina, again, has a different initial distribution; it first appears on the face, neck, and front of the chest. An initial macular rash, or the papular stage of variola, may simulate measles. In measles the gradual onset of the invasion stage, the tendency to sleep, the catarrh of the conjunctival and respiratory mucous membranes, the absence of the backache, severe headache, and vomiting, are distinguishing fea- tures. With the appearance of the rash in measles the fever and all the other symptoms increase; in variola they decrease. The "grisolle sign" is a cer- tain means of distinguishing the papules of variola from the macules of measles : "If upon stretching an affected portion of the skin the papule becomes unpal- pable to the touch, the eruption is caused by measles ; if, on the contrary, the papule is felt when the skin is drawn out, the eruption is the result of small- pox." The differential diagnosis of variola and varicella sometimes presents great difficulty. Varicella is characterized by a short period of invasion, the erup- tion usually being the first indication of ill-health that the child manifests. The varicellous vesicle is located beneath the most superficial layers of the epi- 188 AJIUBICA^' TEXT-BOOK OF DISEASES OF CHILDREN. dermis. The macular stage of varicella is short, and the macule is soft and but slightly elevated above the surface. The vesicle does not become pustular, but remains filled with clear or opalescent fluid for twenty-four or forty-eight hours, and then dries into a light, easily-detached crust. The distribution of the vesicles, abundantly over the back and sparsely on the face and hands, is very characteristic of varicella. Occasionally only the greatest care will enable the physician to differentiate between these two diseases. No one symptom or manifestation can be relied upon, but all the points in the history and develop- ment of a given case must be carefully considered. Prognosis. — The frequency of complications involving the mucous mem- branes in children, and their feeble powers of resistance make the prognosis of variola in eaidy life very grave. According to Moore, the disease is most fatal in un vaccinated children under five years of age. The younger the child the graver the prognosis. " The influence of vaccination for good is unques- tionable, the mortality being 50 per cent, among the unvaccinated in general, 20 per cent, among the badly vaccinated, and only 2-^ per cent, among the efficiently vaccinated" (Moore). Hsemorrhagic and confluent variola are very fatal. The complications that unfavorably influence the result are — pneumonia, empyema, multiple abscesses, septicaemia, pseudo-membranous laryngitis, and entero-colitis. Favorable cases present a mild or no secondary fever, and are not prolonged by complications. Treatment. — There is no drug that will prevent the development of variola in an infected individual. The efficacy of vaccination in arresting or modify- ing the disease after exposure is a disputed question. Curschmann has no con- fidence in the measure. Welch, however, from an experience in 159 cases, believes it to be of great utility, and his results Avarrant the use of the measure in every person exposed to variola: " In order that protection shall be complete it is necessary that the insertion of the vaccine lymph should be made almost immediately after the reception of the contagion ; but if made at a somewhat later date a modifying effect may be obtained. No part of the incubation period should be considered too late to make use of this remedy, since this period is sometimes prolonged beyond its usual limit, in which case a late vaccination may prove of value" (Welch). A child ill with small-pox should be placed in a very well-ventilated room of a temperature of Qc)° to 70° F. The strictest attention should be paid through the whole course of the disease to the smallest details of the hygiene of the patient and the sick-room. If the attack be severe, the hair should be closely cut. The diet should be light and nutritious. Effervescent waters, milk and seltzer, sour wine, champagne or lemon-juice and apollinaris, Belfast ginger-ale, and egg-water form agreeable and nutritious drinks. During the period of invasion the febrile symptoms, vomiting, headache and backache, and the nervous phenomena may demand treatment. A gentle cathartic should be given at the onset of the disease. A febrifuge, like tincture of aconite, spirits of nitrous ether, or a solution of acetate of ammonium may be given in proper doses. Gastric irritability may be controlled by effervescing citrate of potassium, chloroform-water, or subnitrate of bismuth. Chloroform- water and morphine are very useful, combined as follows: ^. Morphin?esulphatis g''- 8- Aq. chloroformi fgij. — M. Sig. A teaspoonful may be given every half hour to a child of five years. Insomnia or convulsions demand the administration of chloral or bromide VABIOLA AND VARIOLOID. 189 of potassium. Baths, temperature 95° F., are most useful to control the fever and nervous symptoms, and they may be repeated every four, six, or eight hours as may be necessary. One of the coal-tar antipyretics may be given. They have a remarkable power to control the pain, nervous symptoms, and fever at the onset of an acute disease. Given in proper doses and in selected cases, their effect is only for good. Applications that irritate and redden the skin are to be avoided. An ice-bag or a cold-water coil to the head lowers temperature and relieves cerebral symptoms. During the eruptive stage, after the development of the secondary fever, the same conditions for internal treatment are met. The fever is to be con- trolled, preferably by the bath, made lukewarm or cool as the season and the condition of the patient dictate. Cool sponging, cool compresses, or the wet- sheet may replace the tub. The coal-tar antipyretics are to be given with caution. Delirium and convulsions are to be met by bromide of potassium, chloral, or the bath ; insomnia, by these remedies or sulphonal. When there is intestinal irritability, chloranodyne is an admirable sedative. Quinine and the tincture of chloride of iron in full doses have the confidence of able practi- tioners as being useful to combat septic symptoms. Variola with mild secon- dary fever will not usually demand alcoholic stimulants. In grave cases moder- ate stimulation should be begun early, and as the strength wanes under the influ- ence of continued septic absorption the alcohol should be pushed to the full limit. A child of five years will take from two to four ounces of whiskey or its equivalent in the twenty-four hours, sometimes more. The nose, naso-pharynx, and throat should receive strict attention to relieve inflammation and avoid septic absorption. Irrigation of the pharynx with solution of potassium chlorate, boric acid, or witch-hazel should be begun early. The writer finds a solution of listerine and hydrogen peroxide one of the most satisfactory local remedies for pseudo-membranous and septic con- ditions of the mouth and throat, for example: Solution of hydrogen peroxide(15 vol.), Listerine each 1 part. Water 6 parts. This solution should be thrown into the pharynx with an all-soft rubber syringe, until thoroughly cleansed, every one, two, or three hours. This is the most satisfactory way to cleanse a child's throat. The same solution, with double the quantity of water, may be used in the nose with the same syringe. When such thorough cleansing is not demanded, the spray from an atomizer will serve, but it should not be trusted in severe cases. To limit the development of the pustules and to prevent septic absorption and pitting a great number of methods of local treatment have been proposed. Secondary streptococcus-infection of the pustules without doubt plays an im- portant part in the cutaneous destruction, septic absorption, and deep pus- formations ; careful cutaneous disinfection during the papular and vesicular stages of the eruption will tend to limit this secondary infection. The skin should be bathed twice a day with soap and water, and this followed by spong- ing with a boric-acid solution 1 : 20, diluted listerine, or corrosive sublimate 1 : 2000. Omitting the soap, the baths, varied to suit the condition, may be continued during the whole course of the disease. Carbolic acid is an excellent antiseptic and cutaneous analgesic. It is one of the most efficient remedies for the relief of the itching and burning that accompany the develop- ment of the rash. Compresses of antiseptic gauze, wet with a hot or cold 190 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. solution, 1 : 500, may be kept constantly applied to the skin. Carbolic acid may also be used in solution with glycerin or in an ointment. An ointment of 4 parts of salicylate of sodium and 100 parts of cold cream is commended. Anti- septics may also be used as a spray or in the form of a powder, as subnitrate of bismuth, boric acid, or a compound of aristol 20 parts, talc 100 parts. Powders are most useful in the late stages of the eruption. Early opening of the pus- tules is a measure advocated by many writers. It seems rational thus to treat the pustules as small abscesses — to open them early, at least upon the hands and face, and treat them antiseptically. A wet compress of antiseptic gauze applied after evacuation and thorough cleansing with a three- volume solution of hydrogen peroxide would certainly prevent additional destruction of the corium from pus-microbe invasion. In the stage of decline iron, quinine, and strychnine, highly nutritious food, and moderate stimulation are demanded. Convalescence is often slow and interrupted by complications. Arsenic, cod-liver oil, malt, iron, liquors, and supporting treatment generally are necessary. The various complications and sequels should receive the most approved medical and surgical treatment. Quarantine. — A child with small-pox should be immediately isolated, and a rigid quarantine maintained until the skin is free from crusts and compli- cating suppurations have healed — a period of from five to six Aveeks. Con- finement in a contagious diseases hospital gives most certain protection to a community, although perfect isolation can be maintained in a private house. For this purpose the highest, best-aired, and most remote room should be selected, opening indirectly, if possible, to the rest of the house. Sheets wet with an antiseptic solution should be kept hung over the doorway. All direct communication of the nurse and patient with other members of the family should be interdicted. Clothing, dishes, excreta, etc. should be disinfected before being taken from the room. All members of the infected household should cease direct communication with the outside world, and all exposed individuals should be quarantined for a period of fourteen days after exposure. VACCINIA; VACCINATION. By THOMPSON S. WESTCOTT, M. D.. Philadelphia. Vaccixia, or cow-pox, is a contagious eruptive disease of the coav, charac- terized by a more or less profuse eruption, upon the udder and teats, of papules which develop into vesicles, and these, by diying, into crusts, or, through rup- ture, into open ulcers. By inoculation of lymph from its vesicle the disease is communicable to man, and is capable of conferring upon him immunity from small-pox more or less complete and lasting. History. — In the closing years of the eighteenth century, among all the civilized nations of Europe and their colonies, the practice of inoculating for small-pox had become the accepted therapeutic procedure for modifying the ravages of this then most familiar and loathsome of diseases. The operation was not, however, always successful in producing mild cases of the disease, and even in its most favorable manifestation the communicated affection was still variola, capable of being transmitted to others by effluvium, and necessitating careful isolation, nursing, and medical treatment. So common was small-pox that, according to the philosophy of the times, every individual had either passed through, or was destined some time to experience, an attack of the disease. In 1776, Edward Jenner, an English country practitioner living at Berkeley in Gloucestershire, was first attracted by a popular belief, common among the dairy-hands of this county, that any one who had contracted cow-pox from milking cows affected with this disease was insusceptible to small-pox, and was not a successful subject for variolous inoculation. This tradition seems to have been quite well known among the dairy -hands of Gloucestershire and the neighboring counties, and to have been noted by other practitioners through- out the farming country. Intentional inoculation of cow-pox had even been per- formed before Jenner's attention was directed to the matter: Robert Fooks. a butcher of Bridport, as related by Pearson, had submitted to the inoculation by means of a charged needle, as early as 1771, and Benjamin Jesty, a farmer of Tetminster in Dorset, in 1774 inoculated his wife and two sons with the cow- pox as a preventive of small-pox. But it was not until the subject received the careful study and experimentation of Jenner, culminating in his celebrated Inquiry, published in 1798. that the practice of inoculating cow-pox was estab- lished upon a clinical and what, at least for the times, must be called a scientific basis. The story of Jenner's struggles to convince his contemporaries of the value of his observations forms a most interesting and instructive chapter in the history of medical progress. The discovery spread with wonderful rapidity throughout the civilized world, and it stands to-day as one of the greatest blessings that human thought and observation have conferi'ed upon mankind. Etiology. — "'Spontaneous"' cow-pox. the term ordinarily though not very accurately applied to cases of vaccinia occurring naturally in the cow^ is an 191 192 A3IEB1CAN TEXT-BOOK OF DISEASES OF CHILDREN. occasional disease among dairy herds. It is spread by contact, being usually carried from one animal to another by the hands of the milkers, who in this way are themselves liable to accidental inoculation. For this reason the affec- tion is almost exclusivel}^ confined to milch-cows, and the eruption limited to the udder or teats, although young calves or adult bulls may be readily inoculated upon the belly, and exhibit phenomena differing in no way from those observed in the cow. The exact nature of vaccinal disease is a question which has been the sub- ject of repeated theorizing and experimentation since the time of Jenner, and even at the present day no consensus of opinion has been reached. Jenner held that cow-pox was occasioned by the accidental conveyance of the virus of "grease," an eruptive disease of the heels of the horse, to which also he attributed, on conjectural grounds merely, the origin of human small-pox. According to his view, a vaccinated person was a small-poxed person who, instead of suffering from the humanized and virulent form of the disease, had contracted it in its primitive mild character. This theory, at least in regard to its ingenious attempt at the etiological unification of cow-pox and small-pox, can be dismissed as a curiosity of medical history. A second theory considers vaccinia as a distinct disease of the cow origi- nating in a specific contagium, and being in no way related to or capable of being originated by any other contagium, however closely its phenomena may be simulated. It is evident that its rejection or its acceptance is to be based upon the proof or refutation of other theories, and thus it can be more readily discussed side by side with the third and remaining theory. This theory, which offers in many respects the most rational view of the question, regards cow-pox as small-pox modified and attenuated by passing through the system of the cow. There can be no doubt that variola can be artificially communicated to the cow, and can give rise to a vesicular eruption resembling in all physical respects the lesions of spontaneous cow-pox, and that virus from these vesicles can be conveyed to man, and produce at the points of inoculation local effects in all appearance identical with those produced by cultivated vaccine-lymph. Experiments of this kind are now quite numerously recorded, among Avhich may be mentioned the successful variolations of the cow performed by Gassner in 1801, and after him those of Thiele of Kasan, Ceely of Aylesbury, Badcock of Brighton, Martin of Attleboro, Mass., Voit, Reiter, and many others. In some cases the virus thus obtained, when used for experimental inoculation upon human subjects, especially in the early removes, showed undoubted evidence of being variolous by giving origin through infection to fresh cases of small-pox some of which were fatal. Martin's variola-lymph produced quite an epidemic of small-pox in Attleboro, Massachusetts, in 1836, and Reiter's experiments in Munich in 1839 had a similar sequel. It is certain, however, that if in the selection of a variolous virus the same care be exercised as was habitual with experienced small-pox inoculators like Sutton and Dimsdale, a variolation of the cow may be effected which will give origin to a lymph that need not necessarily convey infection to those not inoculated. This was shown in the experience with Badcock's variola-lymph ; and, as Crookshank remarks, identical results were obtained by Adams in many cases where lymph from a mild or " pearl " case of small- pox Avas taken as a primary virus for successive arm-to-arm inoculations, with- out having been first passed through the cow. This whole subject was carefully investigated in 1865 by the Lyons Com- mission under the direction of Chauveau, who, even in 1891, still showed him- self the most distinguished champion of the dual nature of the two diseases. VACCINIA. 193 The result of the investigation of this committee unequivocally pronounced upon the autonomy of cow-pox and the impossibility of converting small-pox into cow- pox. A more recent investigation of the question by Fleming, a well-known English veterinarian, confirmed the conclusions of the Lyons Commission. The question is not, however, by any means settled. Even as recently as 1892, Hime of England and Haccius and Eternod of Switzerland, published care- ful studies in support of the older view, and, excepting in France and America, the theory of the identity of the two diseases seems to be gaining ground. To complete the subject it may be stated that several years ago Depaul of Paris established the fact that horse-pox, a febrile eruptive disease of the horse, was capable of being conveyed by inoculation to the cow, and giving rise to a lesion indistinguishable from that of cow-pox. Constantin Paul, indeed, for a time used such virus for vaccination, but the practice fell into disuse after the discovery of a case of spontaneous vaccinia at Beaugency. Pathological Anatomy. — The structure of the vaccine pock resembles that of variola ( Cornil and Ranvier) . It is formed by the softening and liquefaction of the epidermic cells, which appears to be caused by the micro- organisms which early occupy the centre of the pustule. There is a central necrotic zone, a middle zone characterized by tumefaction of the cells, and a peripheral zone of irritation showing multiplication of nuclei (Pincus). The cavity of the pock is partitioned or multiloculated, and its base, thickened and infiltrated with lymph, constitutes the " vaccinal pulp." The derm is always infiltrated with leucocytes. The lymph is a clear, transparent liquid up to the fifth day in the cow and till the seventh or eighth in man ; it maintains its infective qualities at a low temperature, but loses them quickly in Avarmth. His- tologically, it contains leucocytes, red globules (after the eighth, day), granula- tions and cellular debris, free nuclei, and micro-organisms. Keber in 1868, and subsequently Chauveau and Burdon-Sanderson, observed the existence in lymph of minute rounded organisms to which the terms vaccinads or microspheres have been applied. Keber attributed to them the specific properties of the lymph. More recently (1890) the experiments of Straus, Chambon, and Menard have shown that lymph from which these bodies had been removed by filtration loses its infective power, even when injected in quantity beneath the skin, so that it may be concluded that these micro-organisms are the agents of infection. No distinct microbe, however, has as yet been satisfactorily isolated. In 1883, Quist cultivated upon alkaline serum a coccus, which, when inoculated upon a child, rendered it refractory to subsequent vac- cination. Voigt (1885) isolated three micro-organisms, of which one, a coccus, was found capable of causing typical experimental cow-pox in the calf, from which the same organism was again obtained. Garrd (1887) confirmed the results of Voigt, cultivating a coccus which existed in a pure state under the derm subjacent to the pustule, and which caused cow-pox in the calf, but hot in man until after passage through the calf. Varieties of Lymph. — Practically, there are two sources from which vac- cine-lymph may be obtained — either directly from the bovine through the agency of vaccine farms especially established for its propagation, or indirectly therefrom after passage through the system of one or more human beings, the healthy infant being the medium usually chosen. Lymph from the so-called cases of spontaneous cow-pox is very rarely to be had, and is said to be untrust- worthy in its infective powers ; while variola-vaccine must still be considered as of experimental value merely, and not to be ordinarily employed. At the present day it may be said that in no essential respect is humanized virus to 13 194 AMEBIC AX TEXT- BOOK OF DISEASES OF CHILD BEX. be preferred to animal lymph, if Ave except its slightly greater promptness of action, which may, however, have some value in time of epidemics. The pos- sibility of the transmission of syphilis through humanized lymph derived from a syphilitic patient, while exceedingly rare, is still a constant danger, and pleads strongly against the use of any humanized virus except from an unimpeach- able source. In selecting lympli, either from the calf or from the human vaccinifer, a characteristic vesicle from the fifth to the seventh day should be chosen. Symptoms. — When carefully selected and cultivated vaccine-lymph is introduced by inoculation into the human system, the following phenomena will be normally observed : At or close to the site of inoculation at the end of the second or beginning of the third day a slight papular elevation is observed ; by the fifth or sixth day this has become a distinct vesicle, of bluish-white color, with rounded elevated edges and a cupped central depression — the so- called umbilication. By the eighth day the vesicle is perfected, and is then circular, pearly in color, and distended with a colorless lymph, the central depression remaining well marked. On or about this day appears the areola, a reddish blush of the skin surrounding the pock to a distance of several inches, and accompanied by induration and swelling of the underlying connec- tive tissue. After the tenth day the areola begins to fade, the vesicular con- tents begin to dry in the centre, the process extending to the surrounding lymph, which becomes opaque and gradually desiccates, until by the fifteenth day a hard brownish thick scab is formed, which is gradually detached and falls in the fourth week. A circular, depressed, pitted, or sometimes radiated cicatrix remains. If there have been several points of inoculation close toge- ther, a compound vesicle of irregular shape may result. Even with a single surface of inoculation one or more additional vesicles may arise at some little distance from this point. Constitutional symptoms are almost always notable to some degree in a case of primary vaccination. The temperature may rise one or two degrees on the third or fourth day, and remain elevated for several days. In children rest- lessness, irritability, and loss of appetite may frequently be noticed. The axillary glands or the inguinal glands, depending upon the choice of the arm or leg for operation, will usually show some swelling and tenderness for several days. In many cases, mostly those of secondary vaccination, the constitutional symptoms are more severe ; the fever higher, with transient delirium ; nausea or perhaps vomiting ; and distressing headache. Itching of the skin round about the pock is commonly experienced, perhaps throughout the whole course of the case, and this may be so severe as to constitute a true pruritus. Irregularities in the Course. — Various irregular manifestations of the pock have been described by earlier writers, but in later years, since the more general employment of animal lymph, these irregular forms have become much rarer. One peculiar abortive form, the raspberry excrescence, should be men- tioned. Here the pock is rather slow in appearing, and never reaches full development, but becomes a flat, hard, reddish papule, resembling a npevus, and finally, after weeks or months, disappears without cicatrix. It is probably an abortive form, and does not protect against small-pox or subsequent vaccination. Another irregularity is the so-called erupti\^e vaccinia, in which there is a generalized eruption of pocks, the disease manifesting itself as a true exanthem. Very rarely cases have been observed in which the susceptibility of the skin was so great that repeated accidental auto-inoculations took place from the merest scratches of the nails. VACCINIA. 195 Complications. — Inflammatory phenomena, due to traumatism, irritation, infection, or special conditions of the system predisposing to cutaneous disease, are at times manifest. These may vary from a simple erythema to intense phlegmonous inflammation or ulceration and gangrene, with septic absorption. Injury to the pock before complete maturation may be followed by a gangrenous condition of the underlying derm, sometimes giving rise to a peculiar moat-like depression around a central elevated core. Mothers are very prone to attribute any irregularities or unusual violence in the maturation of the pock to " bad virus." Occasionally, especially when human crusts have been used, this may be a just charge; but it can be authoritatively stated that complications arising from impurities of the lymph will almost invariably show their presence long before the pock has reached its full development, usually within a few days after the operation. Erysipelas is very prone to infect vaccination wounds. It may appear as early as the second or third day, and in this case the prognosis is especially grave. Vaccination should never be performed when erysipelas is prevalent, except in face of the greater danger of variola. Grlandular Enlargement. — The natural involvement of the axillary and cervical glands, usually insignificant, may in certain subjects become extreme, and even go on to suppuration during maturation or toward the decline. In children of strumous habit vaccination may act as the exciting cause of chronic enlargement and cheesy degeneration of glands in these chains. Abscess a7id boils may follow in various parts of the body, especially in children of tubercular tendency. Eczema and other skin aflections are apt to be aggravated or relighted by vaccination. Various roseolous rashes may be observed during the maturation of the pock, and are only important as requiring differential diagnosis from intercurrent and perhaps more serious affections, such as erysipelas, scarlatina, and rubella. Impetigo contagiosa has been observed not infrequently, and seems to bear some relation to vaccinia, which is as yet not clearly understood. Syphilis. — Chiefly to Viennois in France and Hutchinson in England are we indebted for the demonstration that syphilis may be communicated by humanized virus through contamination with the patient's blood, which, as Ricord has shown, is always present in the lymph. Accidental conveyance of the disease by imperfectly cleansed instruments used for vaccinating is also to be mentioned. The treatment of complications will not difi'er from that to be employed in the conditions occurring independently of the vaccinal disease. Method of Operation. — Inoculation can be accomplished in numerous ways. Some practitioners advocate a series of superficial cross-bar incisions made with a sharply-pointed lancet or the back of the point of an ordinary bistoury ; others employ a sharply-pointed rake-like instrument made for the purpose, while tattooing with a sharp needle point has been advocated. Alto- gether the most satisfactory method of preparing the spot for vaccination, and one which robs the little operation of its terror to children and mothers, con- sists in gently scraping away the external horny layer of epidermis wnth the edge of a bistoury or lancet held obliquely to the surface. For this purpose a dull instrument is sometimes advocated, but a sharp edge is more effectual and expeditious. An area as large as the little finger-nail can be readily abraded in this manner without giving rise to a whimper on the part of the child. The abraded surface should be slightly red and glazed by the outpouring of lymph, but no blood should be drawn. The next step is the inoculation of the lymph. In arm-to-arm vaccination the lymph is directly transferred from the pock to 196 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. the abraded surface. When the dried animal virus is used, it should be liquefied by dipping into cold sterilized water just before the surface is prepared, so that in the brief interval it may become completely softened. Any portion of the cutaneous surface may be chosen for the insertion, but customarily the outer aspect of the left arm over the insertion of the deltoid is selected. For cosmetic reasons in girls the leg is often preferred, and in this case a point over the head of the fibula or over the junction of the two heads of the gastrocnemius is the usual choice. The primary vaccination of the infant may be undertaken at any time. In the face of an epidemic the new-born babe should be vaccinated within twenty-four or forty-eight hours after birth, and, as the experience of Wolff has shown, in such cases humanized lymph is to be preferred as producing less constitutional disturbance. Ordi- narily, however, the operation may be deferred until about the third month when the child is in good physical condition and before the disturbances of dentition have commenced. Protective Power of Vaccination. — The experience of the past one hun- dred years offers the most just and conclusive evidence of the power of vaccina- tion as a preventive of small-pox. From one of the commonest and most virulent of diseases small-pox has become in civilized countries one of the rarest of the exanthemata. A most significant fact in favor of vaccination is given by Gay in a study of small-pox in London. He states that in the last forty years of this century, owing to improved sanitation, epidemics of measles, scarlatina, diphtheria, and whooping-cough have all undergone a decrease, but that this is only a small fraction of that which has occurred in small-pox, their highest figures not amounting to a tenth part of the decrease of small-pox — a result which is dependent upon only one possible cause, vaccination. Drysdale states that during the epidemic in Berlin in 1872 and 1873 the mortality rose to 243 and 263 per 100,000 ; then, vaccination in the first year of life and revaccina- tion in the twelfth being made compulsory, during the first year of enforce- ment (1875) the mortality fell to 3.6 per 100,000, to 3.1 in 1876, and to 0.3 in 1877. The protective power is not absolute in all individuals, nor can the period of protection be stated for any given case. Marson, whose experience with small-pox in London was very extensive, stated' that the disease was more fatal among those whose scars were imperfect or fcAv in number than in those show- ing well-marked and multiple cicatrices. While some doubt of the value of this theory may be expressed, it would seem wisest to vaccinate in all cases by at least two insertions, sufficiently far apart to prevent coalescence during development of the pocks. As a general rule, it may be stated that immunity in the great majority of cases will be attained by re vaccination every four or five years, and always when small-pox becomes epidemic. If absolute im- munity from small-pox be not conferred, the course of the disease will be greatly modified and ameliorated. In some very rare instances vaccination and revaccination seem to offer no obstacle to the development of severe variolous disease. According to Biedert, after a successful vaccination im- munity is secured in about eight days. Vaccination after infection with variola does not guard against the development of the disease, but if done eight days before the eruption appears the evolution will take place benignly. PAROTITIS. By ANDREW F. CURRIEE,, M. D., New York. By the term " parotitis " is to be understood an inflammation of the parotid gland. By the inelegant term mumps we usually understand an acute infec- tious disease, often epidemic in character, in which the parotid gland is always inflamed, other glands being also involved occasionally. If it were possible to dislodge the terms " mumps " from the mind of the profession and the public, it would be in the line of progress, for, like many other terms which cling to medical nomenclature, it is inaccurate, inelegant, and would be inexpressive were it not for its arbitrary association with acute epidemic parotitis. This affection is usually regarded as one of the diseases of childhood. It is unfortunately true that many mothers think it necessary that their children must experience this and several other infectious diseases at some period of their childhood, forgetful of the fact that disease is always to be avoided if possible. It is true that one attack of epidemic parotitis usually furnishes immunity from others of the same character, but until we are further advanced than at present in the science of preventive inoculation it will not be wise to encourage the acquirement of infectious disease from such a motive. Small- pox, and possibly hydrophobia and tetanus, furnish exceptions to this rule, and the day is probably dawning when the list can be lengthened. Epidemic parotitis is not limited to the period of childhood. Many epi- demics are recorded in which it prevailed exclusively among men. This is especially true of soldiers in garrisons and barracks. Two such epidemics are recorded by Girard in which the testicular complication was severe, and others by Gnasco, Dogny, Jourdan and Laurens. Males suffer with it more frequently than females. But parotitis is not necessarily an infectious disease, for there is a form which is purely traumatic and limited to the parotid gland, and another which may be called an irritative form, in which malignant disease in or near the gland incidentally causes true inflammatory action with infiltration and indu- ration. Of this form nothing further need be said in this connection, the con- sideration of the subject being limited (1) to its traumatic, (2) to its infectious, aspect. Pathological Anatomy. — Writers upon paediatrics have remarked the incompleteness of the knowledge of the anatomy of this subject. This is due to the small number of fatal cases, excepting those in which the disease has occurred as a complication, and in which, from gangrene or abscess, the gland-structure is more or less completely destroyed. Virchow studied the disease in 1858, and his work is fundamental with reference to anatomical knowledge at that period. The development of bacteriological science has modified all our knowledge concerning infectious disease and its eff'ects. In general it may be said, with Ziegler, that the anatomical appearances are those which are due to inflammatory, serous, and cellular infiltration of the inter- 197 198 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. alveolar fibrous tissue of the glands, issuing either in resolution, fibroid indu- ration, suppuration, or gangrene. Bamberger describes the gland as enlarged, red, swollen with exudate in the interstitial tissue, the acini fused together, and the cellular tissue of the entire gland involved. In severe cases the entire glandular substance is involved and converted into a fleshy dry tumor. The exudate may be absorbed, the gland resuming its normal size and consistency, or the exudate in the cellular tissue may become thickened and organized, leading either to permanent increase in size or to atrophy. Etiology. — The two vai'ieties or forms of the disease to be considered are: (1) the traumatic, (2) the infectious. (1) The traumatic variety is the result of blows or bruises, with more or less effusion of blood into the gland and surrounding tissues. The inflamma- tion and SAvelling may be extensive, especially in syphilitic or strumous sub- jects, the great sensitiveness of the glandular system of such individuals ren- dering them peculiarly liable to disease of this character even when the injuries received have only been of moderate severity. It may also be the result of burns about the face and neck or of the application of irritating chemicals and caustics. This form of the disease is entirely distinct from the infectious, and illustrates the fact, which for some time was in dispute, that inflammatory con- ditions are quite possible without the influence of micro-organisms. (2) The infectious form of the disease may be simple or immediate, symp- tomatic or metastatic. That parotitis may be a complication of so many other conditions is an argument against the proposition that it is always caused by a specific microbe. There is scarcely an infectious disease in which it may not so appear. It may complicate pneumonia, diphtheria, and typhoid fever, each of which has its specific cause; hence Ave are obliged to refer it to that very convenient class of diseases known as mixed infections, in which the limita- tions to one who is not a bacteriologist are as yet rather vague. It is quite proper to refer to the work Avhich has been done Avith the vieAv of placing its etiology upon a definite basis (^. e. from a bacteriological standpoint). Pasteur found a bacterium in blood taken from patients Avith this disease, but inoculations of animals Avith cultures obtained from it Avere negative. Bordas described a bacillus found in the blood which he termed bacillus paro- tidis. In certain phases of its development it assumed an S or Y shape ; Avhen divided the ends became enlai'ged. It died at a temperature of 140° F., and its spores at 194° F. Its development was arrested in 1 : 500,000 solutions of mercuric bichloride. Cultures were made from the saliva of parotitic patients, and were rich in the microbe. The investigations of Capitan and Chari'in in this field have been more extensive than others, and have to a great degree furnished a basis for other Avork. They first examined the blood, saliva, and urine from six cases. In the blood AA^ere found small, mobile microbes in great numbers, most of them being spherical, but some rod-shaped. Similar bodies were found in the saliva, Avhile in the urine they detected neither albumin, sugar, nor microbes. In 1881, after a study of the blood in thirteen additional cases, they were able to confirm their previous discoveries. They particularly described a bacterium tAvo to three thousandths of a millimetre long and also a small micro- coccus, the microbes appearing singly, doubly, and in chains. Cultures of the microbes Avere successfully made, but inoculations of dogs, rabbits, and guinea-pigs were negative. These discoveries Avere verified by V^drenes, Bouchard, Netter, and Boinet, the latter finding the microbes in the blood of fifteen patients, also in pus from an abscess of the nucha. Ollivier found the microbes in saliva, urine, and blood from three subjects, and suggested that fiiilure in the inocula- tion of animals was due to the insusceptibility to parotitis of all species of animals PAROTITIS. 199 upon which experiments had thus far been conducted. He believed that we could now see in parotitis not the simple effect of cold, or a manifestation of the rheumatic diathesis, or a propagation of a phlegmasia of the mouth, but an infectious disease caused by a specific agent and propagated by the diffusion of that agent. Jaccoud has expressed himself almost equally hopefully. In the simple or immediate form, which is the usual one in most epidemics, the contamination of the atmosphere with the infectious elements, especially in schools or barracks, 'in which the air-supply is deficient, explains its dissemina- tion. This statement harmonizes with the fact that it is most prevalent in damp and cold weather when the windows and doors of houses are closed and the tend- ency or the necessity is to remain in-doors. The elements of the disease are also carried from house to house in the clothes of physicians and visiting friends. This explains the prevalence of epidemics in sparsely-settled localities. Infec- tion is probably acquired in respiration, and those who are mouth-breathers are the more susceptible. Whether the long period of incubation which follows the reception of the infective influence means retention of the elements in the ducts of the salivary glands or in the glands themselves, or whether there is a process of germination within the blood and localization in the glands, we do not know. The latter is the more reasonable hypothesis from the analogy with other infective germs which are known to develop in the blood. As in all other infectious diseases, the intensity is governed partly by the activity of the infec- tious elements and partly by the resistance of the individual. In the secondary, metastatic, or symptomatic variety of infectious parotitis the inflammation is a complication of a pre-existing disorder. The list of diseases in which it may play such a role is a long one, including the infectious diseases in general, besides nephritis, pneumonia, meningitis, and surgical injur- ies of all kinds ; for in all of them sepsis, and hence infection, are possibilities. As an evidence of extensive or general systemic infection it is a symptom of grave significance. With the diathetic diseases, tuberculosis, syphilis, and rheu- matism, its significance is less grave than with the acute infectious diseases. In this variety we cannot refer to a specific microbe as its origin. Some of the conditions with which it may be associated have such origins (diphtheria, pneumonia), and whether the complicating parotitis is due to the irritating effect of such specific germs which have been retained within the gland, or whether it is caused by those germs (streptococcus, staphylococcus) which produce severe inflammation wherever localized, we do not as yet know. Incubation. — The period of incubation of parotitis is a long one, but it varies with the resisting power of the individual and the virulence of the infective material. The long period of incubation, with the complicating con- ditions which may arise in the mean time, may delay the determination of the diagnosis. J. Lewis Smith regards the disease as primarily a systemic infec- tious one, with an incubation period of nine to twenty-one days ; A. Jacobi fixes it at two to three weeks ; Dauchez, at fifteen days ; Roth, at eighteen days ; and Nicholson reports a case in which an interval of six weeks elapsed between the involvement of the two parotid glands. Symptoms. — The long period of incubation may be attended by symp- toms of impending trouble. This is especially true with young children. There may be malaise with moderate rise of temperature for several days, and with very young children there may be convulsions, especially if digestive dis- order coexist. With glandular swelling come also induration, sensitiveness, pain on motion of the neck or jaw, loss of appetite, restlessness, and insomnia. With the progress of the inflammation infiltration of the gland and the sur- rounding tissues increases, and fever is more pronounced. These symptoms 200 AMEBIC AX TEXT- BOOK OF DISEASES OF CHILDBEX. may continue for a week, and gradually subside, or the duration may be less prolonged. The induration will gradually disappear and normal conditions be resumed, or the gland may be permanently enlarged or it may atrophy. In a certain number of cases abscess or gangrene will ensue, the gland will be destroyed, and the final result be fatal ; but in the great majority these are cases in which the system is so saturated with septic products that the outcome would be fatal even if parotitis did not exist. The inflammatory action which involves the parotid glands may include also the other salivary glands, and even the cervical lymphatic glands. These com- plications are frequently overlooked, being overshadowed by the more exten- sive and apparent affection of the parotids. The appearance of an individual with parotitis is suJBBciently characteristic : there is glandular swelling, with hardness and pain : the swelling may be considerable or inconsiderable, and of course the disfigurement of the face and neck will be governed accordingly. The pain is constant and severe, especially in young children : deglutition is dif- ficult and often impossible on account of its painfulness. If abscess develops, the pain has the acute throbbing character of abscess-formation everywhere. Pain in the contiguous structures of the ear is almost always a marked feature of the disease, and the nearness of the carotid artery and cerebral meninges introduces elements of danger which must always be remembered, for serious results in this quarter are by no means unknown. Considering the possibilities of serious consequences, the small percentage of fatal cases when the disease is uncomplicated is quite remarkable. Complications. — In the traumatic form, in which the inflammation is a simple one, complications are unusual. The inflammation subsides, as such conditions do elsewhere, the result being resolution in the mild cases and sup- puration in the severe ones, especially if the tissues have been bruised and broken. In the epidemic infectious form complications are extremely common, the genital organs being most frequently implicated. Thus with males there is often an involvement of the testicles, spermatic cord, and inguinal glands ; with females, the mammae, ovaries, labia majora, and inguinal glands. These complications may not be evident until the symptoms in the parotid gland have begun to subside. In a recent epidemic in which one hundred and seven- teen cases were observed by Demme, two were fatal from gangrene of the paro- tid glands : in three there was abscess of the cervical glands ; in two there was acute nephritis. Musgrove and Slagle each saw a fatal case complicated with uraemia. P. Smith saw two cases which were followed by insanity, and Par- rott one which was complicated with orchitis and meningitis. F. W. Brown records an epidemic of twenty cases in a boys' school, ten of which were com- plicated with orchitis. Jackson observed four cases complicated with influenza. This latter complication is more frequent than is generally supposed. The writer recently saw such a case in an infant fourteen months old. Among the sequelae of the disease Joff'roy mentions peripheral neuritis, with paralysis of the extremities lasting four months. Rotch and Moure each saw two cases of deafness ; and Dufour, inflammation of the lachrymal glands. The evidence is therefore abundant that we have in parotitis an infectious disease with multiple localization. Treatment. — If the disease be, as it appears, an infectious one, we have, as yet, no method of treatment for aborting it. When the symptoms are apparent, the indication is to relieve them as they arise. The pain may be soothed by small doses of Dover's powder or paregoric, or phenacetin combined with salol. Hot applications to the inflamed parts are always grateful, and the surface may be kept moist with anodyne liniments. The bowels must be PAROTITIS. 201 kept open, fever may be reduced with aconite, and the diet must be fluid and concentrated. Hot liquids will usually be preferable to cold, and will be more quickly assimilated. The skin should be kept active by daily warm baths, by alcohol, and by gentle friction. The opiates suggested will usually be sufficient to relieve restlessness and induce sleep. As soon as the acute symptoms have subsided the nutrition should be improved as rapidly as possi- ble, and a tonic of iron, quinine, strychnine, and arsenic will be indicated. Quarantine. — An important practical question is that relating to the time in which patients with infectious parotitis should be isolated. This especially concerns children who are attending school. A recent paper by Rendu is devoted to this aspect of the subject. His studies have led him to believe that the time of greatest danger of contagion is at the close of the incubation period, at least twenty-four hours before the disease can be diagnosticated. Sevestre and Comby had reached this same conclusion. If this be a fact, Rendu's opinion that it is irrational to keep children out of school three weeks after the symptoms of the disease have subsided is a just one, and teaches that isolation should be limited to a period included between the time when the first symp- toms appear and the time when the active symptoms have subsided. WHOOPmG-COUGH. By J. P. CROZER GRIFFITH, M. D., Philadelphia. Synonyms. — Pertussis ; Tussis convulsiva ; Hooping cough ; Chin cough. Whooping-cough is a zymotic, contagious disease of childhood, character- ized by a catarrh of the respiratory mucous membrane and a peculiar paroxys- mal cough. No description of any disease resembling pertussis can be found in the writings of the Greeks, Romans, or Arabians, and it seems probable that the failure to mention such a peculiarly characteristic disorder is proof that it did not then exist at all, or at least in parts of the world with which medical writers were acquainted. In fact, no account of it is found until Baillou, in 1578, described an epidemic which occurred at Paris, and spoke of it as an affection not previously known. Little or nothing more was heard of it for about a hundred years, when AVillis wrote of "■ tussis ]nieronu72 convulsiva " in such a manner that its nature and its identity with the pertussis of the present day can admit of no doubt. Epidemics did not become frequent until the eigh- teenth century, but the disease then rapidly spread, and by the middle of that century had become widely diffused. From that period onward it has been steadily on the increase, until it constitutes at present one of the commonest diseases of childhood. Etiology. — There are certain factors which seem to exercise a decidedly predisposing influence upon the development of pertussis. There is a very distinct tendency shoAvn for it to occur in epidemics, which appear at intervals of about two years, yet with no great regularity in this respect. The disease may, however, occur sporadically, although such cases are always the result of some preceding case. In the larger cities it is practically endemic, although at times greatly more prevalent than at others. The previous occurrence of the disease in an individual precludes the de- velopment of a second attack. Nevertheless, undoubted exceptions to this rule have been occasionally reported, though they are certainly rare. Whooping-cough is more prevalent in the civilized portions of the world, but its absence from any region seems to depend rather on the fact that it has not yet been carried thither than on any conditions of climate or of race which are unfavorable to its existence. The influence of season has been much disputed, and the evidence is conflicting. It is certainly no powerfully predisposing factor. The station in life and the general hygienic conditions existing appear to be without influence, except in so far as the ill-ventilated houses of the poor may possibly favor the increase of the germs in number or in virulence, even as the crowding and lack of isolation certainly favor their diff"usion. The previous state of the health seems to possess some predisposing power. 202 WHOOPING-COUGH. 203 Most observers agree that weakly, sickly children niore readily contract whooping-cough than do those in good health. It is a well-recognized fact, also, that there is an intimate association between epidemics of measles and of whooping-cough, and it is very widely believed that the existence of the first disease strongly predisposes to the later development of the second. Whether or not the association is an accidental one is still unsettled. The actual pres- ence of any other disease is certainly no bar to the occurrence of pertussis. As with other infectious disorders, there exists a certain individual suscepti- bility to it. Some children never contract it, though often exposed. Age exercises a powerful influence on the development of whooping-cough. By far the greater number of cases occur before the sixth year. After this time the frequency of occurrence diminishes very rapidly, and after the tenth year it is comparatively infrequent. West estimates that over one-half the cases develop under the age of three years. It is sometimes seen in adults, but this is rather uncommon ; the rarity being due partly to the fact that so many have suffered from it while children, and partly to a lessening of the susceptibility with advancing years. It is not common during the first six months of life. It is, however, distinctly more liable to occur at this time and up to the age of one year than are the other infectious disorders of child- hood. There are even a few well-authenticated cases reported in which it appeared to have been contracted during foetal life. It has been widely stated that girls are more liable to develop whooping- cough than are boys. Statistics, however, are somewhat at variance, but certainly show that there is no very material difference in the number of each sex attacked. The sole exciting cause of pertussis is contagion, and so powerful is this contagiousness that by far the greater number of children exposed to the disease will contract it. It is contagious during any part of its course, but particularly in the paroxysmal stage. It is least so in the terminal stage. The nature of the infectious principle can best be discussed when considering the pathology of the affection. As a rule, actual contact with, or close approach to, the sick child is neces- sary for its development in a second case, but even a momentary exposure of this sort is often sufficient to ensure an attack. Several observers have claimed that the disease does not spread readily in well-ventilated and roomy hospital wards. My own experience has not been at all in accord with this. The infectious germs appear to be located in the secretion of the respiratory tract, and are spread by this and by the expired air. Cases have been reported which show that whooping-cough is mediately contagious through a third party or through handkerchiefs or clothing which have presumably been infected by the sputum of a patient. It is probable, however, that the disease is rarely contracted in this way. The contagiousness of pertussis extends slightly to the lower animals, and cases are on record in which these have contracted it from the human subject. The path by which the germs enter the system is not certainly known. Although nearly all the evidence is in favor of the respiratory tract, the few published cases of pertussis in the new-born indicate the possibility of their entrance in other ways, as by the foetal circulation. Pathology. — There are no post-mortem appearances characteristic of per- tussis. The most constant change found is redness and swelling of the mucous membrane of the respiratory tract, with the presence of a considerable quantity of viscid mucus. There is often observed a tendency to congestion of various parts of the body, due to the disturbance of the circulation which naturally 204 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. attends the paroxysms. There are also found the various lesions correspond- ing to the complications which have existed during life. The nature of pertussis has been a much-mooted question, and is not even yet entirely settled. It has been frequently claimed that the disease is a functional disturbance of either the pneumogastric, phrenic, recurrent laryngeal, or sympathetic nerves or of the medulla. According to this view, it is simply a neurosis. Other writers have viewed it as a simple bronchial catarrh due to cold merely, with which is associated a certain nervous element. En- largement of the tracheal and bronchial glands has also been urged as the cause of the disease, through their irritating pressure upon the terminal fila- ments of the pneumogastric nerve. The eminently contagious nature of whooping-cough, its occurrence in epi- demics, the existence of a period of incubation, and the immunity from second attacks seem to prove beyond a doubt that it is to be classed among purely infectious disorders. Although this is the view which has recently found very general acceptance, it is by no means a new idea. Even Linnseus attributed pertussis to the presence in the nose of the larvre of insects. Poulet dis- covered bacteria in the expired air of patients with pertussis. Letzerich found a micrococcus in the sputum which he believed to be the specific germ, and was able to produce the disease in animals by introducing the secretion into the trachea. Deichler claimed that there was always present in the sputum an organism of the nature of a protozoon which possessed amoeboid motion. But, although other investigators have repeatedly described various organisms as existing on the respiratory mucous membrane, the researches of Afanassiew in 1887 have attracted the most attention. This observer isolated a short bacillus, Avhich he named the hacillvs fussis convulsivce, and of which he was able to obtain pure cultures upon various media. Animals inoculated upon the respi- ratory mucous membrane with these cultures exhibited some of the symptoms of the disease and developed catarrhal conditions of the respiratory tract, with a tendency to broncho-pneumonia. These observations have been confirmed by others, and a toxine has also been reported as present in the urine of patients with pertussis which is identical with that produced by Afimassiew's bacillus. Even though it be admitted as most probable that some micro-organism is the cause of the malad}^, it is by no means clear how the symptoms are pro- duced or where the principal seat of the infection is. Some writers have claimed that the trigeminal nerve is in a sensitive state, and that it is the irri- tation of its terminal filaments by the infectious catarrhal process on the nasal mucous membrane which brings on the paroxysms by a reflex action. Others, again, have stated that the bronchial mucous membrane is the portion of the respiratory tract chiefly involved, and that the terminal filaments of the pneu- mogastric are those irritated. The careful investigations of Meyer-Hiini and of V. Herff", however, indicate that the catarrhal inflammation is most pro- nounced in the mucous membrane of the nose, larynx, and trachea down to the bifurcation, but especially so on the posterior wall of the larynx in the inter-arytenoid region, the so-called "cough region." In the production of the cough it would seem probable that a small quantity of mucus, perhaps arising from below, accumulates upon the surface of the "cough region," and there irritates powerfully the hyper-sensitive filaments of the superior laryngeal nerve. Through a reflex action a series of clonic spasms of the expiratory muscles is then set up. At last the crowing inspiration occurs, this depending upon a spasm of the glottis, which, in its turn, proceeds from an irritation of the convulsive centres in the medulla. This process is repeated again and again until the off"ending secretion is expelled. WHOOPING-COUGH. 205 The presence of this secretion does not seem, however, to be an essential to the production of the cough, since paroxysms may be brought on by excite- ment and other causes. This appears to indicate that the irritation of the superior kiryngeal nerve may be central, due to systemic infection. A great preponderance of the nervous element of the disease over the catarrhal is further shown by the greater frequency with which the paroxysms occur at night, since this condition very possibly depends upon a less degree of resistance of the respiratory centre during the night, and a consequent greater ease with which convulsive expiratory efforts are brought about. We therefore clearly have to do in whooping-cough with an infectious, catarrhal process which aflfects particularly, and produces an unusual sensitive- ness in, the mucous membrane presided over by the superior laryngeal nerve. But still more prominent is a great excitability of the nerve itself and of the other nervous portion of the respiratory apparatus, this being probably due to the circulation in the blood of some noxious substance, the product of the in- fecting germs, which possesses a special power over the portion of the nervous system which controls cough. The apparent value in many cases of local treatment directed to the respiratory mucous membrane indicates that the abode of the germs is in this region, whence the poisonous products of their growth are absorbed. On the other hand, the existence of pertussis in the new-born, the result of foetal infection, points to the presence of the microbes themselves in the circulation and in other parts of the body besides the respi- ratory tract. From this point of view their situation in the latter region would be a localization entirely secondary to the general systemic infection and, so to speak, excretory. Which of these theories is correct cannot as yet be deter- mined, although the resemblance of the disease to other infectious disorders cer- tainly supports the latter view. Incubation. — A period of incubation precedes the development of the symptoms. Its exact duration cannot be easily determined, since the onset of the disease is so insidious, and statements vary in regard to it. It is clearly somewhat variable in length, and probably lasts from two to seven days, with an average of three to four days. Symptoms. — It is customary to divide the course of the disease into three stages : 1st, the catarrhal or premonitory stage ; 2d, the paroxysmal or con- vulsive stage ; and 3d, the terminal stage or stage of decline. This classifica- .tion is convenient, but somewhat artificial, since the stages only very gradually pass into each other, and their duration cannot, therefore, be accurately deter- mined. 1. Catarrhal Stage. — There is little in this which is characteristic of the disease. The child gradually begins to exhibit symptoms of a severe cold, with malaise, perhaps slight hoarseness, stoppage of the nose, tickling in the throat, sneezing, irritation of the eyes and a dry, annoying cough. Fever is generally slight and apt to come on in the evening only. Although it has been claimed that the elevation of temperature is an evidence of the infection, it is more likely that the degree of fever is dependent solely upon the intensity of the catarrh. Under treatment there may be a temporary improvement in some of the symptoms, but all of them soon return in force, and the cough particularly is troublesome and gradually grows worse in spite of medicine given. As days pass by it shows a greater tendency to occur in long, severe paroxysms, and is also much more annoying by night. On examination of the chest only a very few rS,les may be heard. Nothing, indeed, is found to account for the severity of the cough. Sometimes, though less commonly, the first stage is characterized 206 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. by a severe bronchitis, with corresponding auscultatory signs and the presence of high fever. The duration of the first stage averages about two weeks, but it is subject to great variations. Sometimes only two or three days elapse before the child begins to whoop. The younger the age, the shorter, often, is the duration of the catarrhal stage. In some instances the disease never passes beyond the first stage, the diagnosis in such cases depending largely upon the existence of the affection in other members of the family. 2. Paroxysmal Stage. — The complete development of the paroxysmal cough marks the beginning of the second stage. The exact time of onset is, as already stated, often difficult of determination. Except for the rarer cases in which the whoop never occurs, it is convenient and most customary to date the paroxysmal stage from the first appearance of this symptom. The paroxysm of pertussis — or the '' kink," as it is freciuently called — is very characteristic. Just before it begins the child seems anxious and irri- table, or perhaps very quiet. It experiences some soi*t of a warning sensation, as a pain in the region of the sternum, or nausea, or a tickling in the nose, or a similar sensation in the larynx with an irresistible desire to cough. It at once drops its playthings, runs to its mother or nurse, or grasps some near object for support; or, if asleep, quickly rises, sits upright, and begins to cough. Sometimes, however, the cough seems to come suddenly, without the premoni- tory sensation. The cough consists of a number of short, explosive expiratory efforts very rapidly following one another, and without any inspiration between them. These continue so long and are so violent that the face becomes turgid and cyanotic, the tongue is protruded and driven against the teeth, saliva flows from the mouth, the eyeballs are prominent, the eyes water, and the pulse becomes rapid and small. The paroxysm lasts a few seconds until at last both cough and all respiration cease. Then comes a peculiar, loud, crow- ing inspiration, the whoop, which is the result of the air passing through the spasmodically closed glottis. Immediately thei-e begins another series of expiratory efforts, to be again followed by the whooping inspiration ; and this process repeats itself several times. The later series of expulsive efforts is accompanied by abundant expectoration of ropy mucus and very often by vomiting. As the paroxysm ceases the cyanosis disappears, and the child is often left pale and exhausted for a short time ; but if it is strong and other- wise well it soon resumes its play. Sometimes a crowing inspiration imme- diately precedes the first series of expirations. Occasionally, too, after the attack seems to be over there is a period of rest for a moment, and the whole process is then repeated. A series of paroxysms may thus continue for as long as ten to thirty and even more minutes. The usual duration of an attack, however, is from a few seconds up to one or two minutes. The swell- ing of the face, the puffiness of the eyes, and some degree of blueness of the tongue persist more or less between the paroxysms, and may constitute quite notable features of the disease. In bad cases the paroxysms may be attended by haemorrhage from the mouth or nose or beneath the conjunctiva or else- where. Involuntary voidance of urine or faeces may be occasioned by the vio- lence of the attack. The frequency of paroxysms and their intensity vary greatly. In mild cases there may not be more than six to twelve in the twenty-four hours, while in the severer ones they may number from forty to eighty. They are always more numerous at night. An attack of coughing is often brought on by exercise, crying, singing, loud speaking, eating or drinking, excitement of any kind, a sudden change of temperature in the air, or the breathing of air WHOOPING-COUGH. 207 overloaded with carbonic dioxide. Depression of the tongue with a spatula, producing gagging, is very apt to bring on an attack. The general condition of the patient does not suffer materially in mild cases. Sometimes, however, there is much exhaustion from the frequent coughing and the loss of sleep, or vomiting may so regularly follow the paroxysms that the nutrition suffers greatly and emaciation becomes marked. In the milder cases vomiting does not at all interfere with the appetite, and the child is soon ready to eat again ; so that quite sufficient food is retained for the bodily needs. More or less fever may occasionally be present in the second stage, espe- cially at night, but, as a rule, fever is absent, and if continuously present makes the existence of some complication probable. The urine in whooping- cough sometimes contains sugar and frequently albumin. It was. at one time claimed that it was always saccharine. Auscultation of the chest in the interval between the paroxysms reveals nothing abnormal, or only the presence of a few mucous rales. During the whooping inspiration nothing at all, or at most only a very feeble inspiration, can be heard. During the expiratory efforts, too, very little respiratory sound is audible, and scarcely more than the sensa- tion of a series of impulses can be perceived. The total duration of the paroxysmal stage is exceedingly variable. In general terms it may be given as from three to six weeks, but it may last a shorter or a much longer time than this. 3. Terminal Stage. — The second stage merges so gradually into the suc- ceeding one that no exact boundary between them can be recognized. The third stage may be said to begin when the severity of the disease is clearly diminishing. The attacks now grow less frequent and less severe ; the whoop- ing and vomiting persist for a time, but gradually disappear ; and the cough, although still paroxysmal, groAvs distinctly looser and of a more catarrhal nature, and finally assumes the character of that of simple bronchitis. Hgem- orrhages occur much less frequently, if at all ; the bronchial secretion is now more muco-purulent, and the general health, if previously affected, improves. Finally the cough disappears entirely and the disease is over. The duration of this stage is very variable. It may last from about ten days up to several months, depending upon hygienic and other conditions. Thus the approach of the winter season is liable to prolong it indefinitely. Not infrequently, after all cough has ceased and the child has appeared well, the development of a nasal or bronchial catarrh may be attended by a return of the paroxysms. Such a return cannot, however, be properly desig- nated a part of the third stage. Complications and Sequelae. — Of the very numerous complications of pertussis those connected with the respiratory tract are most prominent. Bronchitis may be so in excess of the degree of catarrh usually present that it constitutes a complication. This is not an infrequent occurrence. Atelectasis very often develops in young children. It may affect only a small part of the lung or may be more extensive and threaten life, and is especially apt to be witnessed in weakly and rachitic children. Widespread broncho-pneumonia is one of the most common and most dangerous complications of whooping- cough. It usually comes as a result of atelectasis, but sometimes independ- ently of it, and tends to run a veiy tedious course. As it develops the paroxysmal nature of the cough is very liable to diminish or disappear. Like atelectasis it is particularly prone to be seen in weakly children or when measles has immediately preceded pertussis, or in children who have been sub- jected to improper hygiene, especially exposure to cold. Pleural effusion, 208 AMEBICAN TEXT-BOOK OF DISEASES OF CHILDREN. empyema and croupous pneumonia are of less frequent occurrence ; pneumo- thorax is rare ; emphysema is common, but is generally only temporary. Sometimes, however, it is permanent throughout more or less of the lungs. Emphysema of the subcutaneous connective tissue has been reported but is very uncommon. (Edema of the glottis is sometimes seen. The coexistence of pseudo-membranous laryngitis is to be regarded as accidental. A complication so frequent that it almost deserves to be called a symptom is the occurrence of a superficial yellowish-gray ulceration over or at the sides of the friienum of the tongue. It is probably produced by the forcible impulse of the tongue against the lower incisor teeth during the act of coughing. It has occasionally been seen in other disorders than whooping-cough. Vomiting is generally to be regarded as a symptom of the disease, but the irritability of the stomach may become so great that it constitutes a genuine and very troublesome complication. In such cases vomiting is very frequent and takes place after every slight cough. Loss of appetite, indigestion, and diarrhoea are common complications, the latter being of a somewhat chronic nature, with the evacuation of considerable mucus. Prolapse of the rectum may result from the violence of the cough, and hernia may be brought about in the same way. Hsemorrhages from various parts of the body occur during the paroxysms. Bleeding from the nose and mouth is so frequent that it is to be included among the symptoms of the disease. Subconjunctival htemorrhage is not uncommon. Bleeding from the ear is a rare complication and haemorrhage from the lungs is also unusual. Hgematemesis, in which the blood comes origin- ally from the stomach and is not previously swallowed, is certainly exceptional. Haemorrhage into the skin occasionally occurs. Haemorrhage into the meninges or within the brain is not an unusual complication, and is doubtless the cause of many instances of convulsions and other cerebral symptoms. Convulsions are a dangerous complication and are not infrequent, particu- larly in young subjects. A persistent spasm of the glottis may sometimes cause death. Hemiplegia, aphasia, sudden blindness and other evidences of cerebral disturbance may be occasional complications. General oedema of the skin has sometimes complicated the disease. Acute nephritis has been quite often reported. Whooping-cough may be associated with diphtheria, varicella, scarlatina, or, in fact, any of the infectious diseases, but particularly with measles. The latter combination especially renders the prognosis more unfavorable. Rachitis, anaemia and other constitutional maladies may complicate per- tussis and influence its course unfavorably, or they may develop as sequels to it. Tuberculosis is a sequel very liable to arise in those who are predisposed to it or Avhose general nutrition has greatly suifered during the first disease. Its usual seat is the bronchial and intestinal glands or in some of the patches of broncho-pneumonia, but from these foci a more or less widely-spread infection may start. Epilepsy, various paralyses, aphasia, blindness, deaf-mutism fol- lowing rupture of the drum-membrane, disseminated sclerosis and other con- ditions have been reported as occasional sequels. Some of them are to be viewed as accidental merely. Diagnosis. — In the early stages of the disease the diagnosis can seldom be made with any certainty. The absence or scarcity of physical signs in the lungs, coxubined with the very harassing cough, which is markedly worse at night, renders the case suspicious. This is especially true if whooping-cough be prevalent at the time, or if there be a history of exposure to contagion. If the cough assume a decidedly paroxysmal character, the diagnosis becomes still WHOOPING-COUGH. 209 more probable. The occurrence of the Avhoop is usually conclusive, and even in those cases where this at no time develops, the nature of the cough, with such attending symptoms as vomiting, injection of the conjunctivae and the like, makes the diagnosis fairly easy. Severe acute bronchitis of the smaller tubes may sometimes be attended by a very spasmodic cough and may simulate pertussis closely ; but the presence of numerous rales, with decided fever and dyspnoea, and the absence of more than a slio-ht whoop will aid in distinguishing it. The same difficulty in diagnosis, and for similar reasons, may exist in cases where pertussis closely follows measles, since the severe bronchitis already present may appear to account fully for the severity, and even the paroxysmal nature, of the cough. The development of broncho-pneumonia during the first stage of pertussis may render the later diagnosis very difficult, since it is apt to modify greatly the character of the cough or even to prevent entirely the occurrence of the whoop. Tuberculosis of the bronchial glands may produce a paroxysmal cough much resembling that of pertussis. It is to be distinguished by a history of previous wasting and ill-health, the chronic course without distinct stages, the imperfect development of the paroxysms, which are unattended by abundant mucous expectoration or vomiting, and the presence of fever. Sometimes evidences of tuberculosis of the lungs are also present. A prolonged third stage of pertussis may readily simulate pulmonary tuberculosis, and, indeed, it may be possible that the latter disease is developing as a sequel. Only the later course of the case can decide. Prognosis and Mortality. — Although the prognosis is favorable in most cases, yet pertussis is a far more dangerous disease than is ordinarily supposed. In England and Wales 120,000 persons died of it between the years 1858 and 1867, and 85,000 succumbed in Prussia between 1875 and 1880. Dolan ranks it third among the fatal diseases of childhood in England, and says it causes one-fourth of the annual mortality among children in London. Smith esti- mates that during fifty years there were 4840 deaths from it in New York City, or 1 in every 76 deaths from any cause. The relative mortality, as compared with the number of cases of the disease, is also larger than is commonly believed. Statistics vary regarding it, but it may be said to range from 3 to 15 per cent. It is upon the great frequency of the complications that the high rate of mortality depends, for, if uncomplicated, the disease is not often dangerous. The younger the child the more unfavorable is the prognosis. The mortality is very much greater under two to three years of age than after this period, while after the fifth year it is trifling. The prognosis is rather more unfavorable in females than in males, owing possibly to a less degree of strength of constitution pos- sessed by the former. The patient's previous general condition and the amount of care received while sick affect the prognosis very materially. The children of the poor, badly nourished and neglected as they so frequently are, are con- sequently apt to suffer most. Rachitis or any other constitutional debilitating disorder influences the course of the disease unfavorably. The presence of the winter season increases the danger through the greater liability of respira- tory complications. On the other hand, the heat of summer brings on debili- tating intestinal disorders. As already stated, convulsions and broncho- pneumonia are frequent and dangerous complications and the cause of many deaths. Many cases pass safely through the attack, but die from the sequelae. Some become marasmatic and die without the exact cause being discovered, although many of these are undoubtedly tubercular. Other cases show definite symptoms of tuberculosis of various parts of the body. 14 210 AMEIiICA^^ TEXT-BOOK OF DISEASES OF CHILDREN. Treatment. — Prophylaxis^. — In view of the highly contagious nature of the disease prophylactic treatment should be carefully carried out. Children ■who have not yet suffered from it should be rigidly kept from the slightest inter- course with those who are even suspected of being in the first stage of the malady. Inasmuch as there exists the greatest possible carelessness on the part of parents of the sick regarding the danger to others, it is better that unin- fected children be removed entirely from the neighborhood whenever feasible. Particularly is this true in the case of delicate infants. How long the danger of infection continues and how long quarantine must be maintained are not absolutely certain. It is admitted that the infectiousness diminishes during the third stage, and it may be assumed that by the end of two months after the onset of the disease the danger has entirely ceased. A still better criterion, however, is the entire cessation of the cough. If, after the child has been apparently entirely well for a brief period, the cough, with or without the whoop, returns, it is probably safe to consider that the risk of infection is over in spite of this. It often happens that the whoop will thus return at intervals during months, or even for a year, whenever slight bronchitis is contracted. Quarantine during this entire period is manifestly unnecessary and impossible. The same is true of those cases which continue to whoop once or twice a day for an indefinite time. In such we may consider that after two. or at most three, months the disease itself is over, and that simply a neurosis remains: the "habit," so to speak, of whooping persists. Although whooping-cough seems in nearly every instance to be communi- cated by the breath only, yet, to avoid the possibility of transmission in other ways, disinfection of the clothing, bed-linen, and the like should be carried out systematically, and the rooms used should receive a final disinfection before being inhabited by other children. Treatment of the Attack. — The hygienic treatment of pertussis is of the utmost importance. Inasmuch as air loaded with carbonic dioxide has been proven to bring on paroxysms of cough, children should be kept in fresh air as much as possible. At the same time the very great sensitiveness of the respiratory mucous membrane must be borne in mind, and all possibility of taking cold must be avoided. In winter, therefore, it is often best to confine the patient to the house except on dry and still days. Where possible it is well to utilize two airy rooms, one of which shall be thoroughly ventilated and then warmed while the other is in use. The child can be changed from one to the other several times a day. The clothing should be warm enough to prevent chilling and consequent taking cold. The food should be nutritious, easy of digestion and assimilation, and frequently administered in cases where vomiting is a prominent symptom. In some cases of this kind it may be neces- sary to employ nutrient enemata. It sometimes happens that change of climate will act most favorably upon the course of a case of pertussis. This is particularly true of the third stage if unusually prolonged. The host of remedies recommended for pei'tussis is proof in itself that none of them constitute an infiillible cure. Rather, however, than decry all medi- cation, as is the habit with some, we should remember that negative results in the hands of one physician cannot vitiate positive results with any certain method of treatment in the hands of another competent observer. Nothing is more certain than that, although no medication is curative in all instances, many different methods of treatment are of undoubted value in different cases. Where, therefore, we fail with one, another must be tried in the effort to dis- cover the remedy useful for the particular case. It must also be borne in mind WHO OriXG- CO UGH. 2 1 1 that to test the value of a remedy we must give it in sufficiently large dose, and further that it must be administered at the height of the disease, and not when the third stage has already commenced, at ^Yhich time almost anything may seem to do good. In the mild cases, where paroxysms are but few and of little severity, it is best to omit all medication intended to control the disease, and simply to keep a careful supervision over the patient. In severer cases, however, treatment is demanded. The condition existing in each individual case, — and, to a less extent, the stage of the disease — will exert an influence upon the choice of drugs to be employed. During the first stage, when the cough is hard and tight, with little expectoration and without full development of the paroxysmal character, the medicines to be selected are those useful in an ordinary bronchial catarrh. The same plan of treatment may be needed in the second stage, while in other cases the copious expectoration permits the freer use of sedatives. But inasmuch as the cough from the outset does not depend upon a simple bronchial catarrh, it is oftener better to begin the employment of remedies directed against the peculiar nervous character of the disease as early in the case as the diagnosis can be made. This need not interfere with any symptom- atic treatment indicated. When the third stage is well under way attention must be paid principally to the accompanying bronchitis. Stimulating lini- ments to the chest may be useful, and tonic remedies are often demanded. An attempt to consider all the drugs which have been employed for the treatment of pertussis would be so much a waste of time and space that only the most important of them can be mentioned here. Belladonna is one of those best and longest known and most widely used. Sometimes doses of moderate size suffice, but in other cases it is necessary to give it m increasing amounts until constitutional effects are seen. It often does great good, and often, too, entirely fails to relieve. The initial dose for a child of two years may be two minims of the tincture or one-twelfth of a grain of the extract three or four times a day. Alum is sometimes of distinct benefit, particularly when the abundance of the secretion appears to be the cause of frequent paroxysms. It may be given in doses of two grains every three or four hours at two years of age. It may sometimes be combined advantageously with belladonna. Quinine has been widely used with varying results. On the whole, it may be con- sidered a useful remedy. When given internally the doses should be rather large — as one grain every two to four hours at two years of age — to produce an effect upon the disease ; but there is risk of disturbing the digestion with it. It may be administered with advantage in suppositories, or, if by the mouth, disguised in syrup of yerba santa or syrup of licorice. Chloral is often use- ful to produce sleep at night. Two to four grains may be given at bed-time to a child two years old. There is some evidence that, administered at inter- vals during the day, it exerts also a direct influence upon the course of the disease. It can be exhibited either by the mouth or by enema. Its power of depressing must not be forgotten. Opium is frequently of the greatest service in obtaining temporary relief. Comparatively restful nights can often be pro- cured by means of its administration at bed-time. It should, however, be re- served for the severest cases. Bromide of potassium or of some other base has been much recommended, and is often of distinct value. It lessens the nervous irritability, and in this way diminishes the frequency and intensity of the paroxysms. Its administration should be started immediately if evidence of nervous disturbance indicate impending convulsions. The dose at two years of age may be two to five grains, repeated according to the demands of the case. It may often be advantageously combined with belladonna. Cannabis 212 AMERICAX TEXT-BOOK OF DISEASES OF CHILDREN. Indica has been much used, and is probably one of the most reliable means of treatment. Asafoetida is still a favorite with many. Carbolic acid, in doses of one minim at two years of age, has been found of service in many instances, but its toxic properties must not be forgotten. Peroxide of hydrogen has been highly praised, as have terpens hydrate and infusion of wild thyme. Ouabaine has been highly recommended. The dose is one-thousandth of a grain every three hours at five years of age. It is a powerful respiratory paralyzer. Among the most important of other drugs which have been recommended for internal administration, and which have doubtless proved of service in some cases, are pilocarpine, lobelia, resorcin, grindelia', castania, drosera, cam- phor, quebracho, hyoscine, turpentine, benzole, carbonate of iron, and conium. Antipyrine, first recommended by Sonnenberger, has been used with excellent results by so manj^ that its value in the disease is now beyond ques- tion. Although, like other remedies, it often fails to relieve, many of the reported failures with it are doubtless due to the fact that it was not given in sufficiently large dose. Children bear it surprisingly well, and bad results following its administration are rare. The initial dose should be small, and the amount gradually increased until a child two years old receives one to two grains, or even more, every three hours. In a desperate case of pertussis in a four-months-old child under my care, in which three-quarters of a grain of antipyrine, given every three hours, failed entirely to relieve, an increase of the dose to one grain every three hours rapidly brought the patient from a condition of the greatest danger to one of comparative health. The child had sufi"ered from very frequent and violent attacks of cough, followed by spasm of the glottis of so long duration that intense cyanosis Avith entire apnoea and loss of consciousness repeatedly resulted. Within forty-eight hours after the treatment had been instituted the little patient had passed an entire night and and until afternoon on the next day with but a single paroxysm. Phenacetin will sometimes be of service in cases where antipyrine has failed, and the reverse, of course, also holds good. Acetanilid has sometimes proved of use, but is less often employed and of less value than are its two cogeners. Bromoform, one of the newest remedies for pertussis, was first recom- mended by Stepp in 1887, and has been largely used. It may be given in doses of from two to four drops three or four times a day at two years of age. It can be dropped upon moistened sugar or given in a mixture with alcohol, syrup, and water. My experience with it, although satisfactory to some extent, has not been as much so hitherto as published results had led me to hope. Some cases improved, but oftener small doses failed to be of service, while larger ones rendered the patient so sleepy and stupid that the remedy had to be abandoned. Nevertheless, the large number of reported cases in which the results have been extremely good indicate that the remedy is certainly of great value. Local treatment of the respiratory mucous membrane has been largely em- ployed. One of the most popular methods is the insufflation of quinine in the form of a fine powder. This may be applied directly to the larynx by the physician twice a day, or nasal insufflations may be made by the attendants several times daily. Excellent results have been obtained in each way. About one grain of quinine should be used at a time. Resorcin has been highly recommended by Moncorvo. A 1 per cent, solution may be applied to the pharynx and the opening of the larynx, or a powder may be insufflated into the nose, using one-half to one grain at a time for this purpose several times each day. The local application of a solution of cocaine has been advo- WHOOPING-COUGH. 213 cated, but is not without danger, as reported cases have shown. It has, however, often been of service in mitigating the severity of the disease. The solution should be of the strength of from 1 to 4 per cent. With the steam or hand-ball atomizer the fauces and nares may be sprayed with the substances mentioned or Avith a weak solution of morphia. Bromide of potassium in solution is sometimes of much service, and tannin can be employed in the same way. Peroxide of hydrogen, in the dilution of one part in five, may be sprayed in the nares and upon the fauces, and very excellent results have been claimed for it. Benzoin, boric acid, salicylic acid, iodoform, tannin, and other drugs, in powdered form, have found their supporters as useful agents for nasal insuf- flation. Benzoin is one of the best of them. Good effects can also be secured with boric acid. Various volatile substances may be used with the atomizer in the form of vapor from boiling water. Carbolic acid is one of the best of these, and it is often of great advantage to allow the sick-room to be permeated by it. The action upon the cough is probably due in part to the anaesthetic effect of the carbolic acid, and largely to the influence of the moist atmosphere of the room, which loosens the mucus and facilitates its expectoration. Thymol, eucalyptol, and turpentine may be vaporized in a similar way. Chloroform and ether have been recommended for their general anaesthetic effect. Remarkable results have been reported from the fumigation of the sick- room by burning sulphur. The child is to be washed in the morning, dressed in clean clothes, and placed in another room. The night-room is in the mean time thoroughly fumigated with the sulphurous vapor, closed during five hours, and then aired. The patient sleeps in this room at night. A single employment of this procedure has been effective in some cases. The inhalation of the air in the purifying-rooms of gas-works is a method of treatment formerly much in vogue. The employment of the pneumatic cabinet has likewise been recommended. The use of the constant electric cur- rent has been advocated by several clinicians. The routine administration of emetics, once a popular procedure, is no longer in favor. Complications demand, of course, treatment applicable to them individually. TYPHOID FEVER. By CHAS. WARRINGTON EARLE, M. D., Chicago. Typhoid fever may be defined, and its clinical history fairly outlined, as a disease caused by a specific germ and characterized by headache, continued fever, and a tendency to hnemorrhage and intestinal disturbances. It is a dis- ease which has a special anatomical lesion, characterized by an eruption upon the mucous membrane of the intestines, and in many cases by lenticular spots of similar character upon the integument. There is every reason to believe that typhoid fever is a disease handed down to us from antiquity. It was undoubtedly known to the ancients and described as a continued fever characterized by diarrhoea, tympany, pain in the abdomen, hi^morrhage from the nose and bowels, delirium, and a tendency to coma. During the early part of the century this disease was particularly studied by the French and Germans, and by Gerhard, Shattuck, and Steele of our country. The non-identity of typhoid and typhus was clearly established about 1838 to 18-40, and what is now believed by the majority of students to be the essential bacteriological fiictor, a characteristic bacillus, was discovered by Eberth in 1880 in the viscera implicated by the disease. Previous to 1840 the opinion prevailed quite universally that infancy and childhood were im- mune from this disease ; but if one I'eads the article by Stewart (Diseases of Children, 1841) entitled "Infantile Remittent Fever," it is readily seen that under this heading he was describing tj'phoid fever. This disease possibly existed in children during all the generations, but had not been differentiated. If we go farther back and examine the earlier wu-itings of those who devoted themselves to the study of typhoid among the young, we shall find additional evidence of this disease among children. As early as 1817, Abercrombie de- scribed a case in a six-months-old girl, and later in a seven-months-old child, and finally, three years later, two other cases. All of these children had the post-mortem results usually found in typhoid fever. In 1822, West described the disease quite fully, not only from a clinical, but from an anatomical, stand- point. Billard, in 1828, published two cases of typhoid in children. Charac- lay, in 1840, recorded a case of a child eight days old who died from typhoid. It presented enlargement of the follicles and patches of the bowel, and also enlarged mesenteric glands. Shadier narrates a case of a seven-months' child whose mother died on the twenty-sixth day of typhoid fever. Five days after the mother's death the child sickened, and died on the eleventh day. " It had ulceration and infiltration of Peyer's patches, swelling of the mesenteric glands, and enlargement and softening of the spleen. Other cases are at my com- mand, but enough have already been recorded. Since the date mentioned (about 1840) typhoid fever in children has received considerable attention, until at this time the fact is established beyond doubt that they not only have the disease, but that, incident to their age, there are characteristics, both 214 TYPHOID FEVER. 215 as regards etiology and clinical history, which should receive our consideration. It is particularly noticeable that epidemics take place which principally affect children. This occurs when there is infection of the milk-supply which a con- siderable number of the young in a community are using for food. I shall speak of typhoid as occurring first in infants, and second in children. That it is found in infants, as I have previously remarked, there is not a d*oubt. I desire to cite cases in current literature. A case is recorded in Keating' s Oyclopcedia of an infant six months of age who had the disease. There was no doubt as to the diagnosis, since the pathological lesions were exhibited by Murchison before the London Pathological Society. In the same work is a previously unpublished case of mine, in which is given the history of a child twenty-four months old who had all the classical sj^mptoms of typhoid, followed by intestinal haemorrhage, the autopsy revealing the usual pathological findings. In the Londoyi Lancet of Jan. 2, 1892, Dr. Ogle records a case of enteric fever in a child four months and fourteen days old. The pathological conditions were present. The same authority states that Murchison mentions three cases in younger infants — one of eight days, one of fifteen days, and one a foetus of seven months. Vogel cites seven cases under one year of age, in one the child taking the disease at its birth, the mother being infected. Henoch had eight cases under two years of age, and. Montmollin recorded fifteen of the same age. England of Montreal reports a case in a hand-fed infant of eight months. In this case there were vomiting, diarrhoea, tympanites, enlargement of the liver and spleen, rose-spots, and elevation of temperature for three weeks. The proportion of children over five years of age aff'ected with typhoid fever is as follows : In' 280 cases observed by Henoch, 154 were between five and ten years of age, and 62 were between eleven and fourteen years. In 1017 cases observed by Vogel, 412 were between five and ten years, and 393 betAveen the ages of eleven and fifteen. My own observations during the last tAvo years are based upon 21 cases whose histories are very complete, and some 15 or 20 others whose records are not sufficiently accurate to make them of particular scientific value. Of my cases, 7 were under five years, 9 between five and ten, and 5 between ten and fifteen. Etiolog-y. — The time has come when some tangible cause for typhoid fever must be assigned for its prevalence. It is hardly admissible at this day to state that this fever comes from exposure to the atmosphere, or decomposing logs or potatoes in the cellar, or from some sewer, or from tainted food. The majority of authorities recognize a specific bacillus which is found in every lesion of typhoid fever. These bacilli have been demonstrated in milk and in drinking-water, and in other sources from which it is fair to suppose the infection may take place. This discovery may be stated as one of the triumphs of bacteriology. That the typhoid bacillus has been found in any consider- able number of cases of typhoid fever in children cannot be claimed ; indeed, in a careful examination of all literature at my command, I do not remember that this peculiar germ has been found in children dying of typhoid under two years of age. Studies must be made along this line. Eberth, however, reported the case of a pregnant woman who, in the third week of an attack of typhoid fever, expelled a twenty-week foetus still enclosed in its membranes. With rigid antiseptic precautions some blood from the heart, some pulmonary tissue, and some fluid expressed from the spleen were taken from the foetus. In cover-glass preparations of these, as well as of the blood from the inter- villous spaces of the placenta, typhoid bacilli were found. Cultures in gelatin and on potatoes developed typically. Comparative observations upon eight 216 AMERICAN TEXT- BOOK OF DISEASES OF CHILDREN. other foetuses of non-typhoid mothers demonstrated the absence of typhoid bacilli. The bacilli are found in every lesion of typhoid fever. This is particularly true of the lymphoid tissues, the spleen, the liver, mucous membrane of the alimentary cimal, the blood, and the urine : sometimes it may be demonstrated in the rose-spots and in the ulcerations of bed-sores. It is found in large quantities in the f*cal matter, but it is extremely difficult to separate *it from the other micro-organisms which are found in large numbers in the dejections. While my belief is that typhoid is due to the germs which I have described, and that, according to many observers, when the micro-organism under discussion has been experimentally communicated to animals, it causes them to manifest the symptoms of this disease, there are those who do not at this moment entirely accept this theory. Vaughan, whose work in bacteriology certainly is not to be disregarded, maintains that typhoid is not dependent upon a single specific organism. He admits that the bacillus of Eberth is invariably found in the bodies of those dying from typhoid fever, but he makes a point which is true, that the attempts to introduce typhoid into the lower animals by inoculation has, up to this time, not been absolutely successful. Space wnll not permit me to enter into the question so ably presented by Rodet and Roux, whether an organism may be benign in one location and a disease-producing agent in another ; that is, whether the bacillus coli com- munis, which exists normally in the intestines, is converted into the typhoid germ of Eberth outside the body. This, with the crucial test, the successful inoculation in animals, will undoubtedly be demonstrated in due course of time. The causes which, up to this time, have been supposed to produce the disease, such as bad ventilation, bad sewers, decomposing vegetables, etc., undoubtedly have their influence in favoring its development. All these things furnish a place for the accumulation of the poison, and make those who are exposed to the specific poison more susceptible of taking the disease. I am not aware that typhoid fever is particularly afi"ected by climate or season of the year. When children are exposed to the infection, it Avill man- ifest itself unless the infection is destroyed ; and where the water-supply is contaminated or the milk is infected, we should expect the disease, whatever the climate or season may be. In regard to the entrance of the poison, water is one of the most common means of conveyance, and inasmuch as children have access to all sources of water-supply, it is difficult to give them instructions by which they may avoid it. Milk is undoubtedly a source of infection. The milk which chil- dren take may be very easily infected through the water with which it is diluted or with which the cans are cleansed. It is easy for milk to become contaminated with the dust and other impurities Avhich contain the bacillus of typhoid. Taking everything into consideration, it appears to me that children are exposed quite as frequently as adults. While typhoid fever is not particularly contagious, in the sense of the disease being contracted from personal contact, yet in different ways it is communicated, and precaution should be taken and instruction given to prevent it. I cannot express my belief in regard to the infectiousness of typhoid fever better than by relating the following, which has come under my own observation : Some time in June, 1890, a young man died of typhoid fever in this city. I was not his attending physician, and do not know what general methods of preventing the spread of the disease were taken, but a TYPHOID FEVER. 217 very intimate friend of his visited his room a short time after his death, burned some of his clothes, and sent some to his home. In about two weeks this young man was taken with headache and general malaise, and went to his home in Wisconsin and passed through a course of typhoid fever. Two sisters nursed him through his sickness. After his recovery, one of the sisters came to Chicago, and was stricken with typhoid, in which I attended her, while the sister who remained at home also successfully passed through an attack of the disease. An aunt with two of her children visited the infected home, and shortly after presented all the symptoms of typhoid, and one of the children aged three years, contracted it and was sick four months. The sister who nursed this child succumbed to the disease after a three weeks' illness, during which time she had four haemorrhages. A distant relative of the sister- in-law visited the house, passed through a short course of typhoid fever, and died in three weeks. One servant in attendance also lost her life. In all, some thirteen or fourteen people had typhoid fever, the starting-point of which was a single case in this city. In my 21 cases accurately recorded 10 were males and 11 females. In Yogel's 1017 cases 870 were boys. In the 35 or 40 cases which I have ob- served during the last three years the duration has been from seventeen to forty-five days, with an average of twenty-six. Patholog-y. — I have already indicated how the specific poison of typhoid enters the body, and, if not destroyed, how it finds favorable conditions for its development. Nearly all the anatomical lesions which we find in adults have been found in children. I have seen the swollen and ulcerated tissues of the mucous surface of the bowel, the opening made by a perforation and its subse- quent peritonitis, the enlargement of the mesenteric glands, and a few of the remote pathological changes. Although the bacilli, which are always found in the lymphatic tissues of the bowels, the spleen, and other organs in adults, have not, to my knowledge, been found in children dying of typhoid, I believe that further study and observation will demonstrate their presence. I have already mentioned Eberth's recent investigations, which give all that is at my command regarding the bacilli of typhoid in children. They have not been found in children under two years of age, as far as my investigations have extended, and in recent communications with Drs. Jacobi, J. Lewis Smith, Rotch, and Northrup, no additional information in regard to this question has been received. Uffelmann remarks that there is almost always redness and swelling of the bronchial mucous membrane, and also adds that the bacilli may be found in the blood, spleen, and other intestinal organs, although he does not state that they have been found in young children. The lesions as they occur in children, in distinction from their occurrence in adults, have not been well worked out by recent authors. It has been the custom in many cases to simply take the pathology of adults, and imply that the same conditions are found in children. The best study on this subject to which my attention has been directed while writing these pages is by Gerhart, from whose observations I shall freely quote. In children the pathological lesions, whatever they may be, certainly differ from those found in adults, and this is especially true at the beginning of the disease. The swelling of Peyer's patches shows itself earlier and is seen with greatest frequency near the ileo-csecal valve, although in a considerable number of cases this lesion reaches high up into the small intestine. The patches are swollen to such a degree that they project from the surface of the mucous membrane, and upon these projections frequently are seen small excoriations and little ulcers. It is from 218 A^IEBICAN TEXT-BOOK OF DISEASES OF CHILDREN. these points that hiemorrhage takes place ; and later sloughs and deep ulcers are formed, which may perforate the outer serous coat of the bowel and give rise to peritonitis. In 44 post-mortem examinations of one author, ulcers and slouo-hs Avere found in 20. In young children, between two and seven years of ao-e, these deeper pathological changes in the mucous membrane are not found as frequently as they are in older children. After the tenth year slouo-hino- and ulcers are more frequent. The comparative insignificance of the changes which are found in the intestinal mucous membrane in young children, as contrasted Avith the same more serious pathological conditions noticed in older people, is due to the fact that in children the nourishment is almost universally fluid, and consequently unirritating. If perforation occurs, it usually takes place after the third Aveek, although it may occur before. The mesenteric glands are found swollen in nearly half of the cases, and sometimes reach the size of a pigeon's egg. These glands may soften and rupture into the peritoneal cavity, giving rise, as I have noted in another place in this article, to serious peritonitis. The gall-bladder has been noticed in one case as a seat of infiltration and perforation during typhoid. SAvelling of the spleen is found in quite a number of cases, although it can hardly be expected that this organ will be enlarged as frequently as in adults. Rilliet found the spleen enlarged five times in sixteen post-mortem examinations. The liver is also occasionally enlarged. Hypostatic congestion of the lungs is not as frequent as it is in adults, although very serious complications do sometimes find their seat in the lung tissue. Clinical History. — Typhoid fever in children conforms very fairly to the disease as I have noticed it in adults. This, hoAvever, is contrary to the previous experience of some of our best observers, particularly Wilson. According to Unger, the clinical history differs in a great degree in young children. The symptoms referable to the prodromic period, hoAvever, are either absent or not noticeable in very young children. The pain in the head so constant in older patients is frequently present in the young. In some cases the parents have noticed that the child has had uneasy nights, rolling and tossing about : in some instances a fever has been present several days before a physician is consulted. There are frequently Avant of appetite and some diarrhoea, but in the majority of cases the symptoms Avhich cause parents to consult a physician are fever, more particularly during the first tAvo Aveeks, at night, sometimes a slight diarrhoea or a feeling of Aveariness, and, in a fcAv instances, nose-bleed. The irritation of the gastro-intestinal canal in typhoid fever is less, not only in children but also in adults, than it was a few years ago. Whether this change has been brought about through a different treatment or from rest in bed, Avhich we make imperative, or because Ave feed more and medicate less, I am unable to say : but that there has been a change brought about in the clinical history of typhoid during the last quarter of a century there is in my mind no doubt. Consideration of Individual Symptoms. — Teynperature. — Fever is usually noticeable from the first, and ranges from 102° to 105.5° F. This symptom is never absent, and begins Avith a gradual rise in the temperature, marked usually with morning remissions and evening exacerbations. At the end of the first week, in many cases, the fever has reached its height, and may remain at that point, with slight morning and evening variations, until the decline of the disease. There are no sudden, unprovoked jumps in the curve, as in la grippe and tuberculosis, and under strong antipyretics the temperature falls easily. Usually at the end of the third Aveek or commencement of the fourth the morning temperature declines. It will usually be found, as Henoch 219 220 A3fERICAN TEXT-BOOK OF DISEASES OF CHILDREN. states, that the temperature is somewhat higher in the evening. Children with high fever frequently make excellent recoveries. I have seen recently a temperature of 105.6° for three days, with a subsequent perfectly good result. Headache. — I have already remarked that this is not as noticeable a symptom as in adults. The reason of this is manifest, since infants and most children locate pain indefinitely. The facial expression and the indication of uneasiness, however, point to this symptom as present in many cases among the young. Appearance of the Tongue. — The tongue does not have, in all cases, the characteristic redness Avhich Ave formerly noticed in adults. In the majority of cases it is only slightly coated, while in others there is a heavy coating, with edo-es slightly red. In some cases the tongue is remarkably clean. I do not now remember seeing any instance of the red, hard, glistening beefsteak tongue that the older authorities refer to. Dr. Christopher of this city believes the conditions of the tongue quite diagnostic of typhoid in children. He describes the coating as thick and heavy over the major part, but leaving the tip and margins free and slightly red. Sometimes he finds a V-shaped reddish appear- ance in the centre of this organ. The mouth and pharynx may be the seat of catarrhal inflammation, and in children Avith poor nutrition there is a tendency to superficial and deep ulcer- ation. Pharyngeal diphtheria is recorded by Vogel as frequent. Noma has also been noticed. Parotitis. — The parotid gland is the seat of an inflammation late in the disease in a fcAV cases. In my observation it occurred in one case on the right side. Resolution took place without suppuration. Vogel says that the par- otid swells sometimes in children during the second week of typhoid, and Striimpell believes that this infection comes from the mouth, finding its Avay along Steno's duct, and states that proper cleansing and disinfecting will prevent it. Vomiting. — This symptom will be found in a fcAV cases, severe rarely, but slight in quite a number. In Henoch's table there were 42 cases, and Vogel remarks that this symptom takes place Avith greater frequency than in adults. The initial vomiting is absent in the very great majority of cases. Appetite. — There is usually anorexia from the beginning, but Avith a little urging a sufficiency of fluid food will be taken. Co7idition of the Boivels. — Formerly diarrhoea Avas the rule, but at the present day constipation is present in probably one-third of our cases. Of the 21 cases of typhoid in children Avhich I have recorded, constipation was present in 3, slight diarrhoea in 10, severe in 8. In Henoch's cases 23 were constipated, and in 224 other recorded cases diarrhoea was present in 175. Gurgling and pain may be found in the right iliac region. Rose-spots. — Pale red, slightly elevated spots, which disappear on pressure, are found in the majority of cases. They are few in number oftentimes, but sometimes not only are very abundant on the abdomen, but are found in great numbers on other parts of the body. They were found in all my cases except 4, 1 of Avhich was seen late, Avhile the other 3 Avere not specially examined. Henoch says that rose-spots were absent in 15 of his cases, but were usually found. They are noticed generally from the seventh to the eleventh day. Tympany. — Henoch speaks of tympany as being rare. This was not true in the cases under my observation, as a majority shoAvedmore or less distention. In one case a very extreme tympany developed on the tenth day, with marked nervous symptoms ; and in a second case extreme tympany developed during TYPHOID FEVER. 221 convalescence in association with obstinate constipation. Both symptoms were relieved by free bowel movements. Hcemorrhage of the Bowels. — In my unpublished case in Keating' s Oyclo- pcedia this symptom was present, while in our recent epidemic none took place. Henoch noticed it nine times. Vogel says intestinal perforation is rare, and in my own experience it has occurred only once, many years ago. It appears to be a rare accident in children, and with the care in diet now given by every intelligent physician it will undoubtedly take place less frequently than in former years. Peritonitis in a mild form is probably present in a fair percentage of cases. When severe it is usually due to perforation, although it may become a danger- ous symptom even without perforation. In the light of recent pathology this is possible, and may be explained as follows : 1. Microbes, such as the bacte- rium coli commune and others, may migrate directly through the weakened and partly destroyed intestinal wall, and then attack the peritoneum. 2. Periton- itis may originate from thrombo-lymphangitis and lymphadenitis by direct extension to the peritoneum over the mesenteric glands. 3. A suppurative lymphadenitic focus may rupture into the peritoneal cavity. 4. Peritonitis might originate from the rupture of suppurating infarcts in the spleen or from extension of suppuration about splenic infarcts to the overlying peri- toneum. The Spleen was found enlarged in 70 per cent, of my cases, and could usually be demonstrated by percussion, but rarely by palpation. Swelling of the spleen in children is one of the characteristic signs, and the organ is fre- quently painful on pressure. In one of my cases a considerable part of the left side was painful, and in a second case pain over the spleen was severe and localized. Vogel demonstrated splenic tumor 606 times out of 662 ; it was palpable 36 times in 101 cases. Henoch found splenic dulness in 140 cases, and Filatow speaks of splenic tumor as one of the cardinal symptoms of typhoid in children. He says that it usually can be demonstrated about the fourth or fifth day — that it is absent in only 10 per cent., and can be palpated in about half the cases. The Liver may and probably does preserve its normal condition throughout the great majority of typhoid attacks. I have personally noticed no changes, and mention in literature is rare. The Kidneys maintain their function remarkably well. Urine is sometimes scanty in children, and micturition somewhat painful. The value of Ehrlich's test is perhaps not so important in children as in adults, inasmuch as the reac- tion occurs in miliary tuberculosis and other diseases in children. Albumin- uria, either as a result of the fever or during convalescence or associated with acute Bright's disease, will occur in rare cases. Epistaxis. — This symptom will be observed in a fair proportion of cases. It was slight in several of the cases I have seen, and severe in a few. Vogel •remarks that nose-bleed in typhoid in children is rare. Laryngitis is rare, but is found in a few cases. In a little patient under observation at this time it is present to such an extent that there is complete aphonia. It will be unimportant in this case, but it may in other instances develop into a formidable symptom. Post-typhoid necrosis of cartilages of the larynx is far from uncommon. Vogel says that inflammatory conditions of the cartilages may take place, and Henoch reports 4 cases of laryngeal ulcerations. Bronchitis is found with considerable frequency, and pneumonia followed by gangrene of the lung is recorded by some authors. 222 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Hypostatic Congestion — by which is meant a state in which a portion of the hing, usually the ])ase, is congested, dense, and unaerated — is liable to be present in all long-continued cases, unless great care is exercised in causing the patient to change position from time to time. Headaclie, with its peculiarities, which is so pronounced in the adult, has already been noticed in the general history of the disease. In the flushed face and injected conjunctiva Ave certainly have evidence of it in children, to what extent, however, it is difficult to say. In mild cases there seems to be but little disturbance of the nervous system, while in the severe form symptoms are very jironounced and meningitis is simulated. Continued crying took place with some of my patients, especially at night. There were also jerking of the muscles, grinding of the teeth, and stiffness of the neck, particularly among the ver}'^ young. Delirium and hallucinations were rare, although in a few of my cases delirium was very severe, and con- vulsions took place in two instances. In one case Avhich I have had under observation recently delirium, especially at night, was very marked at the end of the third and the beginning of the fourth week. This boy, aged twelve, talked and yelled, .refused to take his nourishment, picked his nose and eyes, making them bleed to such an extent as to require his hands to be tied. In a second case, during the third week the delirium was so severe and the apathetic and indiff'erent condition so marked that the little girl, aged five, pulled nearly all of the hair from the top of her head, leaving it absolutely bald. She tore the bedding and clothing with her teeth and filled her nose and ears with the fragments. She tore every button from the front of her night-clothes, and would chew everything that she could reach with her mouth. Both of these children made a good recovery. Speech was absent in one case for five weeks, and in a second for two weeks. Recovery in one was sudden, while in a second and third it was grad- ual, and, indeed, it seemed to be necessary to teach these children to talk. Henoch speaks of complete aphasia in 15 cases, and says that it ahvays occurs at the commencement of the remission of the fever. This does not agree with my observations. Hearing in one of my cases was completely lost for three weeks ; recovery, however, was perfect. Otitis media suppurativa of a very offensive character was present in one case in which the nervous phenomena had been extremely pronounced during the early part of the disease. Sight is interfered with rarely, yet Henoch reports 2 cases of amblyopia. The Memory is impaired in a few cases, but all under my observation have recovered. Paralysis is rare, although one case is recorded. The Pulse. — In the cases which have come under my observation more recently the pulse has ranged from 90 to 180, usually keeping pace with the temperature tracings. This corresponds with the observations made by Henoch. Filatow says that the pulse is slow in comparison with the fever, and that this is more marked the older the child. A slow and irregular pulse indicates some meningeal complication. Pericarditis occurs very rarely, while endocarditis takes place with slight additional frequency. Phlebitis occurred in one case, the affection making its appearance in the profunda femoris vein. Arterial Stenosis has occurred in a recent case of mine, not, however, in a child, but the symptoms were so peculiar and the pathological findings so remarkable that it appears to me important to mention the complication. TYPHOID FEVER. 223 Periostitis ^as observed in one case, the parietal bone being involved. Qelhditis takes place occasionally, and can usually be traced to some infection by the patient. In one case, the history of which I have preserved, a septic cellulitis in the forearm, followed by diffused abscess, was caused by infection from the finger-nail of the patient. Bed-sores occur occasionally, notwithstanding all care that may be taken to prevent them. Dr. Hare says that the occurrence of bed-sores is a sign of a poor doctor. It appears to me, however, that in some cases — where prostra- tion is D-reat, the poAvers of life poor, and the conveniences for avoiding this complication limited — it will take place. Sepsis from a collection of pus in the middle ear has not, to my know- ledge, been mentioned. It is believed to take place, and from observations recently made it appears that Ave should inspect the drumhead from time to time in order to acquaint ourselves Avith its condition. The Facial Expression appears to me almost pathognomonic. It some- times seems that, with a history of the fever and the appearance of the face, Ave have enough to diagnosticate the disease. And later in the course, as we look at the flushed cheek and the almost insensible appearance of the patient, with half-closed eyes, a dried tongue, a mouth full of sordes, with absolute unconsciousness of surroundings, and with a perfect indifference to the ordinary Avants of nature, we appreciate, as we do in hardly any other disease, what Ave intuitively call the " typhoid condition." Post-typJwid Pains take place in a considerable number of cases. In the first of which I have a record the pain was so severe in the thigh as to suggest an osteomyelitis. In another case severe pains were present in the chest ; in a third, in the left arm and upon the left side of the chest, persisting several days. In a fourth case severe pains of a general character folloAved a relapse, and in another pains were located for many days in the shoulders and feet. Relapses take place in a fair percentage of cases, notwithstanding all the care taken to prevent them. The duration of these relapses has been from fif- teen to twenty days. The fever is less severe than in the preliminary attack, the temperature usually marking from 102° to 103.5° F. A considerable number of the primary symptoms Avill be present, such as epistaxis and diar- rhoea. According to one observer, there were in 670 cases 65 relapses. Post-typhoid Temperature. — There is a rise in the temperature in many cases after it has remained normal for one or two weeks. It increases from one to three degrees above normal, and usually seems to have been brought about by some error in diet, by fatigue, or constipation. This exacerbation usually subsides in about a week. Diagnosis. — The diagnosis of typhoid fever in young children is fre- quently attended with difficulty. Trivial complaints, from slight indigestion and Avorms to the most dangerous general diseases, such as acute tuberculosis, have been confounded with the malady under consideration. In genei-al, during the first week watch for local processes as the cause of the fever and exclude the eruptive diseases. By the end of the second week rose-spots will frequently have made their appearance, and the symptoms referable to the gastro-intestinal canal will be quite pronounced. All local and eruptive diseases may now be certainly excluded. Influenza, also, may at this time be disregarded. With the history of the first and second week in mind, by the end of the third week the observer Avill probably have the majority of what I may desig- nate as the cardinal symptoms to consider, i. e. : 1. Headache Avith an indif- ference to external surroundings and with an apathetic expression of the coun- 224 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. tenance ; 2, fever, more noticeable at night ; 3, gastro-intestinal disturbances ; 4, rose-spots. It is not necessary that all of these symptoms be present, but they can be mentally discussed. Some will have been present and disappeared, others will be noticeable. By the end of the third Aveek, if neither splenic tumor nor rose-spots are present, we should at least bear in mind the possibil- ity of tuberculosis. Malarial fevers, as they occur in children, simulate many of the symptoms found in typhoid. I am not at all surprised that for years intelligent physicians have confounded the two diseases. The fever and hebetude in an infantile remittent are very much like those which we find in typhoid ; but as time goes on and we notice the tendency to hgemorrhage, the intestinal disturbances and the rose-spots, it appears to me that we should have but little trouble in excluding this disease. The effect which quinine has on this class of diseases will have its influence in diagnosis. Typhus fever, as it occurs in other countries and affects particularly chil- dren, is regarded difficult to differentiate. The rapidity of all the symptoms, particularly the rise in temperature, the development of the disease as a whole in a few days, so different from typhoid, and the peculiar eruption, will usually enable the physician to make his diagnosis. Influenza, or " la grippe," in many instances has such gastro-intestinal disturbance as to simulate typhoid fever. In my judgment, we do not get the prostration in typhoid as early as in influenza, and the organs are earlier involved in la grippe than in typhoid. The entire disease (influenza) will have exhausted its fury, either on the gastro-intestinal canal, respiratory apparatus, or nervous system, by the time a typhoid is fairly developed ; and it is not usual for such unexpected and rapid changes in temperature to take place in typhoid as we find in the other disease. Meningitis, either simple or tubercular, is a disease which will seriously tax the diagnostician in differentiating from typhoid. In meningeal diseases there are usually vomiting at the onset, violent and excruciating headache, and fever, particularly in the acute form. In this form, however, the invasion is very rapid. The pulse, too, is usually slow and ii'regular in meningeal disease, and the tendency to sleepiness and coma appears earlier than in typhoid. In typhoid fever tympany is usually present, while in meningeal diseases we expect a retraction of the abdominal walls, and later the boat-shaped or scooped-out appearance of the abdomen. In tubercular meningitis the previous history of the case, the family history, and its slow progress will usually determine the difficulty. Advantage might here be taken of a suggestion of Georgevitch, to puncture the spleen and make cultures of the blood thus obtained, in order to determine the presence or absence of the bacillus of Eberth. Chronic gastro-intestinal catarrh is another disease from which typhoid must be differentiated. The history of the case, with attention to the tempera- ture range, and the absence of rose-spots and splenic tumor, will usually lead us in the right direction. Empyema is a disease which has been confounded with typhoid fever. It would seem, however, that a thorough examination of the chest would establish the case. The fever, the slight cough, the want of appetite, and the slightly increased respirations are all symptoms which we find in typhoid, but the dis- covery of flatness over a considerable amount of chest-surface should determine the diagnosis without very much trouble. Prognosis and Mortality will be different in different epidemics. The percentage of deaths is much less than in former years, and Ave have every TYPHOID FEVER. 225 « rig-ht to believe that, Avith the restriction we now make in diet and with the rest we order, the diminution Avill continue. One authority makes it 14 per cent., and one as low as 5. In 20 cases among children which I have recorded during the past two years not a death took place. Several years ago, when we were having sporadic cases, I had a death from perforation, and later another from exhaustion and haemorrhage. Dr. Forchheimer of Cincinnati in the epi- demic of 1888 treated seventy cases without a single death. Treatment. — There are a few cardinal principles in regard to the general management of typhoid in children which must be observed throughout the entire disease. The first is rest in bed ; second, a restriction to fluid diet ; third, attention to temperature and intestinal antisepsis ; and fourth, the administration of a general nutritive tonic. The treatment of symptoms — that is, something for the liver to-day, and some other drug to stimulate or diminish the activity of the kidneys to-morrow, or a little aconite or belladonna for the fever, or somethino; for the tongue — seems to me, to say the least, unnecessary. Many who are treating typhoid in this manner fail to comprehend the salient feature of the disease, which should be constantly in one's mind. Projjhylaxis and Hygiene. — It goes without saying that children Avith typhoid fever should be separated from not only other children, but also the family, and that all communication between the sick and those uninfected should be as rare as possible. All water and milk should be thoroughly sterilized, and the room in which the little patient is sick should be light and airy, and should be so arranged that easy and thorough ventilation is possible. In the introduction of fresh air the patient of course should not be exposed to direct currents. All dejections should be thoroughly disinfected, either with carbolic acid, the bichloride of mercury, or the sulphate of copper, or, what seems to me equally good and easily prepared, a thin mixture of ordinary lime. If the above very direct suggestions could be carried into eifect, we would diminish the cases of typhoid fever we are obliged to treat ; and I am firmly of the belief that a cer- tain number of cases con be aborted if, in addition to prophylaxis and hygiene, we would early put our patient to bed, give a fluid diet, and possibly some intestinal antiseptic. Rest in Bed. — This must be absolute, and should commence as soon as we suspect the disease, and be continued, without interruption or concession, until the patient has been from four to ten days without elevation of temperature. I place this among the cardinal points of treatment, for I believe that many cases have gone from bad to worse simply because the physician has not insisted upon the rest which I have suggested. Children who are fairly well advanced in typhoid should be kept where they are, rather than sent to hospitals or removed, if at any distance, to their homes. I believe it is not good practice to remove patients, yet sometimes it seems absolutely necessary, and may be accomplished Avithout detriment, although in other cases a removal, even for a short distance, has seemed to retard recovery or even produce a fatal ter- mination. Diet. — Instructions in regard to fluid food should be explicit, and from these directions there should be no deviation, no half-hearted concessions. The food I direct is usually milk or its equivalent in some fluid form. It is just possible that occasionally a larger amount is taken into the system than can be properly cared for, and that those undigested masses of caseine and fat which are sometimes found in the dejections may be responsible for the unreasonable persistence of fever sometimes noted. Children from two to five years of age 15 22(3 AMERICAN TEXT-BOOK OF DISEASES OF CHILDEEJS\ may take from a pint to two quarts of fluid food a day. If it disagrees with the stomach or if they insist upon some change, add lime-water, seltzer, or ordi- nary pop ; or the milk may be skimmed or predigested. If milk is not rel- ished, mutton-, chicken-, or oyster-broth or beef tea may prove acceptable. Koumyss is relished by many of these little people, and agrees with them com- paratively well. If beef tea is to be used, let it be prepared as follows : Put a pound of beef, cut into small pieces, into a pint and a quarter of cold water, and allow it to stand for one hour, at the expiration of which time place it over a fire and let it evaporate slowly to ten or twelve ounces. In my judg- ment, this is a much better beef tea than is usually obtained at the drug-stoi'es. The egg-water Avhich I have suggested so many times in other diseases is fre- quently well taken by these little people at this time : Take the white of one egg, an equal amount of sterilized water, a little sugar, and 10 or 15 drops of Avhiskey or brandy ; agitate sufficiently to thoroughly mix, but not form a foam. This is not only nourishing, but is relished exceedingly well. The liquid pep- tonoid is a palatable food, and possibly has some medicinal properties. Usually, then, Avith milk or cream properly diluted, the various preparations of the ani- mal broths, koumyss, and the egg-water, a sufficient nutrition is provided for these patients. When, after four or five weeks of fever, tAvo days have elapsed Avithout rise of temperature, I alloAv a small amount of cream- or milk-toast. In tAA'o days, if this does not disagree Avith the patient by producing gas and uncomfortable sensations in the digestive tract, I allow the child a baked potato with plenty of butter. If, with the addition of the cream- or milk- toast and the baked potato and butter, there is no increase in temperature for ten days, the patient is alloAved to sit up for a short time and commence to chcAv beefsteak or mutton-chop. Before this I sometimes alloAv the red juice from the roast beef or a little beefsteak juice, expressed Avith a lemon-squeezer. From this time forAvard there should be a slight increase in the amount of food allowed each day until the patient is upon a diet sufficient to nourish him. I need not say that to maintain a child upon a fluid diet for all of these Aveeks, in the face of its importunities and those of its parents, is difficult, but it must be insisted upon. Whenever I have encountered a relapse, it has usually come from errors in diet. Bathing. — A moderate degree of fever is not to be dreaded, and unless it goes to 10-3°, I am not in the habit of administering any antipyretic remedy. I control the temperature by cool baths Avhen the children do not oppose it in a great degree. It will, hoAvever, be impossible in private practice to carry out in detail, in all cases, the Brand treatment as used by the Germans or the Bouch- ard treatment as suggested by the French, It A\'ill be Avell, however, to take advantage of a full knoAvledge of these methods, and then vary th-em as the con- dition of the child seems to demand. It aaIII be practicable, in most cases, to reduce the temperature by placing cold towels over the child, rather than to put it into the full-length bath. Under the direction of a competent nurse the temperature in such cases will be reduced without much trouble. Medicines. — Rest, a fluid diet, and cool bathings are all that is needed in the treatment of many cases of typhoid in children. Medicines, hoAvever, are useful in some cases and for some symptoms. They give comfort to the patient, and modify AAhat might become a dangerous and serious complication. I have noticed at another place in this article that with rest and a fluid diet and some intestinal antiseptic, probably the bichloride of mercury, some cases of mild typhoid fever are really aborted. Sometimes there seems to be a malarial element in a case, in Avhieh event quinine in moderate doses may be administered for a fcAv days. Quinine should usually be given in the forenoon ■ t TYPHOID FEVER . 227 and exhibited in either syrup of licorice, yerba santa, or chocolate tablets ; inunctions are useful for the very young. In case it is suspected that the fever is of malarial origin, the administration of a laxative to clear out the aliment- ary canal as completely as possible early in the disease would certainly be advisable. Early in the disease I am in the habit of prescribing a general tonic, or, what is a better name, a restorative medicine, which in many cases is persisted in from first to last. A great array of medicines is entirely use- less. Combinations will have to be made from time to time, but they should call for small amounts and be made as palatable as possible. The restorative medication to which I have already referred is made up somewhat after the fol- lowing formula : I^. Pepsin cordial f^ss. Compound syrup of hypophosphites gtt, xv. Aromatic sulphuric acid gtt. j-iv. Aromatic water q. s. ad fgj. A dose of this combination is given four times a day. When there is constipa- tion I usually substitute muriatic for aromatic sulphuric acid. In addition to the general directions in regard to the diet, rest in bed, and the administration of the restorative medicine mentioned above, orders are given to sponge the surface of the body with tepid water in case the tempera- ture goes to 103°. Sometimes a preparation of phenacetin is prescribed, with instructions to give an appropriate dose if the temperature goes to 103.5° or 104° and is not reduced by the cold bath. I can state with definiteness that from 2 to 3 grains of phenacetin given to a child from eight to ten years of age with a temperature of 104° will reduce it almost without a doubt to 100° or 100.5°. I have tried this many times, and can speak with confidence. This, in my judgment, is the best remedy at our disposal if we must administer a drug for the reduction of temperature. I have never had the success with administering the large quantities of quinine that some of my colleagues have had. I think that large doses of this remedy in the midst of typhoid fever are sometimes harmful. Intestinal antiseptics probably stand next in importance to antipyretics, and perhaps should even take a precedent rank. The toxine or poison formed or made more malignant in the system during the course of the disease is coming to be a question of very great importance. It has seemed to me that a full dose of some of the salines or castor oil at the onset of the disease was in many cases really indicated, but, as I shall say at another place, it has not been my custom to administer these cathartics. Of the intestinal antiseptics, salol, thymol, naphthaline, the salicylate of bismuth, the mercurials, and turpentine are among the best at our command. Treatment of Individual Symptoms. — For the headache, delirium, and restlessness which are present in many cases bromide of potassium, either alone or in combination with chloral, gives the best results. For a child four years of age I order 4 to 6 grains of potassium bromide and 2 grains of chloral hydrate in syrup and water. In severe cases phenacetin may be given, or, if the prostration is not great, 2 grains of antipyrine and 6 grains of potassium bromide in syrup and water. For the aphthge and different forms of stomatitis, potassium chlorate, with carbolic acid in combination, will be found useful. For the vomiting, bismuth subnitrate, with carbolic acid, made up somewhat after the following formula, nearly always has a good eff"ect : 228 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. I^.

A few drops of any anodyne may be given with each dose if needed, or a little tincture of geranium if the diarrhoea is very troublesome. For the relief of the constipation which is persistent in many cases enemata should be given every second day. I am not in the habit of advising laxa- tives or cathartics after the first week, except in rare instances. For the tympany any of the saline preparations or intestinal antiseptics may be used, but asafoetida has certainly given the best results. A small amount of the tincture in water or the mistura asafoetidie of the Pharmacopoeia may be used. In some cases the patient may be placed in the knee-elbow position when enemata are given. The haemorrhage of the bowels is best treated b}^ absolute quiet, the ice-bag, and elevation of the lower extremities. It is possible that ergot with some astringent may be beneficial. If perforation takes place, in addition to the above the question of lapa- rotomy should be considered. It is so difficult to find the opening, and the patient is frequently in such collapse before the operation can be performed, that the advisability of such a course is in my opinion not fully established. Possibly as many lives are saved without as with the operation. Peritonitis should be treated by I'est, hot applications, and opium. The liver is involved so infrequently that medication is hardly necessary. The same may be said of the kidneys, although sometimes I am in the habit of ordering additional water, and sometimes a few grains of the citrate of potassium. For epistaxis, cold to the nose and the insufflation of some of the astrin- gents should be used. The bronchitis is best relieved by the usual cough mixtures into which a small amount of ipecac, paregoric, and muriate of ammonium enter. Hypostatic congestion should be prevented by frequent changes in position and by the administration of stimulants. TYPHOID FEVEB. 229 Impairment of the special senses is usually relieved by attention to the general nutrition, which is brought about by diet and tonics. A discharge from the ear should be treated with absolute cleanliness and the use of anti- septics. It is not necessary to pay much attention to the pulse in the early history of the disease, and I am not aware that aconite and its substitutes are of any benefit. Later in the disease digitalis, or, if the pulse is very weak and rapid, nux vomica and the ammonia preparations, may be demanded. Keep the patient absolutely in the recumbent position, and add alcoholic stimulants to the above remedies. Indeed, there is a time in some cases of critical ty- phoid in children when some form of alcoholic stimulant, freely administered, seems to carry the patient from the most desperate and dangerous condition to one of safety. Such local manifestations as periostitis and cellulitis are best treated with the wet boric-acid dressing. EPIDEMIC CEREBRO-SPmAL MENINGITIS. By ROLAND G. CURTIN, M. D., Philadelphia. Synonyms. — Epidemic meningitis ; Fever with cerebro-spinal meningitis ; Meningeal fever; Petechial fever; Malignant purpuric fever; Spotted fever; Cold plague. Definition. — Epidemic cerebro-spinal meningitis is a specific infectious fever (probably of microbic origin) in which the poison seems to have a special pre- dilection for the meninges of the brain and spinal cord. It attacks the young with greater frequency than any of the fevers outside of those belonging espe- cially to childhood, and with more severity than any of the continued fevers. The onset is abrupt (without prodromes). The prominent symptoms are chill, more or less marked ; vomiting ; headache ; delirium, generally present in the first and second day, later stupor and coma ; pains, muscular and neuralgic, in trunk and limbs ; stiffness or contraction of the muscles of the neck, rarely lower down the back — all of which symptoms indicate inflammation of the meninges of brain and spinal cord. Recovery may be quite rapid, when the disease is of short duration and the nervous system is not seriously afi"ected. In most cases, however, recovery is exceedingly slow. Death is common among children, especially in severe epidemics. The immediate causes of death are convulsions, kidney complications, exhaustion, bed-sores, and abscesses or gangrene. If epidemic cerebro-spinal fever occurred prior to the commencement of the present century, it was not recognized as a distinct disease. It was first discovered in Geneva. In America the first reported cases occurred in Med- field, Mass., in 1806, and since that time it has occurred in frequent epi- demics in different parts of North America, and in fact it is reported as an irregular epidemic visitor in all parts of the world. A sporadic form of cerebro- spinal fever is recorded yearly in the mortality statistics of all the larger cities of the United States: in studying the death-reports it must be acknowledged and remembered that some physicians call simple acute meningitis and other meningeal forms of disease, especially the continued fevers and tubercular meningitis, by the name of cerebro-spinal fever. Btiolog-y. — The specific cause has not been positively determined. There are physicians who have announced the discovery of a microbe similar in appear- ance to the pneumococcus, but it has not been satisfactorily proved that this is the specific causative germ. However, it is generally conceded that the dis- ease is of microbic origin. In a New York medical society meeting recently a physician stated that he had made autopsies upon 3 cases of so-called sporadic cerebro-spinal fever, and found specific germs of other diseases, all different. One had the typhoid fever germ without intestinal evidence of the disease. I am of the opinion that 230 EPIDEMIC CEREBROSPINAL MENINGITIS. 231 ■when we perfect our bacteriological knowledge all these sporadic cases will be found to be due to infection of the brain and spinal cord by germs that usually aflfect other tissues. Epidemic cerebro-spinal meningitis is an infectious disease, and it is ques- tionable whether it is contagious or not. Widely-separated districts are simul- taneously visited by epidemics, and over extended districts isolated individuals are attacked at the same time; so that the idea of its being transmitted by direct contact in these cases is untenable. Owing to the fact that this disease has followed epidemics of influenza, and on account of the many points of sim- ilarity in the two aff'ections, Drs. Job Wilson and J. J. Levick have been led to suppose that there is some connection between the two diseases. It is more common in the winter and spring than in the summer months : hence the name "cold plague" has been given to it. Slight injuries, especially to the head, fatigue, exposure to cold, and mental depression are exciting causes. Pathology. — In the early or congestive stage nothing is found in the brain and spinal cord except a congested condition of the meninges; the blood-ves- sels are enlarged and gorged with blood of a dark color ; later, after exudation has taken place, the serous plastic exudate is found, especially upon the pia mater. In some malignant cases the exudation is found to be sero-purulent. The lungs are observed to be in a state of hypostatic congestion : where lung complications have preceded death we find evidences of croupous or catarrhal pneumonia, and not infrequently inflammation of the pleura and pericardium. Parenchymatous inflammation of the liver has been noted by some writers. Congestion and sometimes an inflammatory condition of the kidney are found. The heart is flabby, and the blood in malignant cases is frequently observed in a fluid condition. The dusky spots or mottling that are occasionally encoun- tered in malignant cases may be found in all the internal organs as well as on the skin. Symptoms. — The first symptom generally noticed is a chill, which may be a slight creep or a profound rigor ; this usually comes on without any warn- ing, and generall}' in the later part of the day ; it sometimes follows fatigue or perhaps exposure to cold, and occasionally follows injuries to the head. Some cases are stricken down suddenly, as if by a blow, without any previous warn- ing. Headache is one of the most constant symptoms ; it is not always an indication of the gravity of the disease. The pain is almost always frontal, generally located between the eyes, and quite often spoken of as bitemporal; it is not infrequently located in the occipital region. It is sometimes excru- ciating, causing the patient to cry out and toss about; at other times it is a dull, heavy ache. It is sometimes intermittent, at others constant ; it may be fixed or lancinating. The pain in the head seems to be the cause of one of the prominent facial symptoms — viz. knitting of the eyebrows. An attack may be ushered in by a convulsion, or by a sudden giddiness, causing the patient to have a stao;2erincr gait; this criddiness mav onlv be present while the patient is sitting or standing, or may continue after assuming a recumbent position. Ihis symptom is sometimes complained of throughout the disease. Delirium is rarely absent ; it is more apt to be noticed early in the case, extending through the stage of congestion and sometimes through the whole of the inflammatorv stao-e ; it is exceedino:lv variable ; it mav be wild excitement, terrorizing, playful, or sombre. The child may continually mutter or now and then cry out. Delirium is especially common in children, and may indicate the gravity of the disease. Coma almost invariably precedes death, and is always to be considered a grave feature ; coma vigil is a serious ataxic symp- tom, in which the patient Jies on his back, chin raised, eyelids widely separated, 232 AJIEBICAX TEXT-BOOK OF DISEASES OF CHILDREN. apparently regarding fixedly some object above the head of his bed. and is accompanied by constant jactitation. The headache, as before stated, often gives the appearance of great suffer- inc, the brows being knit, especially when the patient is aroused ; the cheeks are often flushed early in the disease, but not always so : later the face is fre- quently pale. In some rare cases the flush is not to be seen at any stage of the disease. In some patients the features are swollen and of a dull, dusky, purplish hue. Strabismus is more frequent in children than in adults. Spinal pains are quite common, the pain being in the back of the neck, some- times extending down to the lower end of the spine. Pressure and movement have the effect of increasing the suff'ering ; the limbs and trunk are sometimes very painful : the pain may be of neuralgic character, radiating from centre to periphery, and may attack one set of nerves, and remain constant or change to other nerve-trunks or groups. Local muscular pains and soreness are not infrequently present. Tonic spasms give rise to tetanoid symptoms, such as opisthotonos, pleuro- sthotonos. emprosthotonos : the foiTner is the most common, the head being drawn back and the spine curved backward, so that the patient's body is some- times supported by the occiput and heels. Forced movement increases the spasm as well as the spinal pains. In many cases these muscular spasms are a simple stifiness of muscles or groups of muscles. Clonic spasms are frequently met with. Subsultus is one of the common symptoms, sometimes amounting to a violent agitation; more commonly it is simply a twitching, and may be the forerunner of convulsions ; this symptom is sometimes present before the inflammatory changes in the nervous system are sufficiently developed to produce it ; hence the reasonable supposition that it is a result of the irritation produced by the blood-poison. Paralysis occurs as a result of a loss of nerve-power, which may be caused either by central trouble or by inflammation of the trunk of the nerve supply- ing the part. These paralyses are sometimes temporary, at other times long continued or permanent. Sudden loss of hearing or sight usually comes on at the time the efl"usion takes place. Strabismus is especially common m children, and is often a precursor or an associate of convulsions. The conjunctivae are quite frequently congested ; at other times this symptom is absent, especially in the milder cases. In almost every case where there is kidney complication the conjunctival congestion is associated with a purulent secretion, which then be- comes quite diagnostic. The pupil varies greatly : early in the disease it may be found to be dilated or contracted, but it is generally dilated. In cases with coma and convulsions it is almost invariably dilated. Photophobia is especially common in children. The effect of the blood-poison upon the kidneys is to produce a catarrhal inflammation in these organs similar to the catarrhal troubles found in other organs. The respiratory apparatus is involved in the disease, and some of the fatal complications are seated in the lungs. Respiration is exceedingly variable. Early in the disease it is likely to be hurried, and at times, later on, it may be exceedingly slow ; it is sometimes interrupted or jerking, and the Cheyne- Stokes variety is not infrequently seen in the later stages of fatal cases. This latter is not so grave a symptom in the case of children as in adults. In some instances death occurs suddenly from paralysis of the muscles of respiration. Pleurisy, pneumonia, and bronchitis are complications which may occur at any time during the course of the disease. In exceedingly malignant epidemics there is a dusky mottling of the skin EPIDE3IIC CEREBROSPINAL MENINGITIS. 233 and the internal organs, the color being purplish ; whence the name of " spotted fever" often applied to the disease. These spots (which are oval in shape) are usually from one-third to one-half an inch in their longest diameter. I have seen them on almost every tissue or organ, external and internal, of the body after death they may be of a slate-color with a chocolate tinge, or quite black 1 had an opportunity in 1864 of seeing 14 cases of epidemic cerebro-spinal fever 4 of which died ; 2 out of the 4 cases had these spots. In the Philadelphia Hospital epidemic I saw over 200 cases : the mortality was 43 ; of the fatal cases, 2 had these mottlings ; one of them was the first case that occurred, and died after fifteen hours' illness. About sixteen years ago I was called in consultation to see two young girls near Point Breeze, Philadelphia ; they both had these mottlings ; one died in twenty-four, the other in thirty-six, hours. At the time only one other suspected case had occurred in the neighborhood ; this also was a malignant one. The two girls had visited the abode in which this patient died. Aside from the mottlings, there is nothing else that seems characteristic of this disease in connection with the skin. Cutis anserina, simple erythema, rubeoloid eruption of a bright cherry-red color in sthenic cases (darker in the adynamic), dermatitis, miliary eruptions, herpes, petechiae, and ecchymoses, have all been noticed. Hypersesthesia is one of the most characteristic symp- toms ; the skin is sore to the slightest touch, and at times the pressure of the bed-clothes is sufficient to produce great discomfort. Anaesthesia of the skin has also been observed ; it may be a simple numbness, at other times a positive insensibility. In some cases the skin is found to be very hot ; in others it may be quite cool ; and occasionally the patient is drenched in perspiration even when the symptoms are not of a grave nature. The temperature of cerebro-spinal fever is exceedingly varied, so that in a group of cases in the same epidemic it is quite dissimilar. The local inflam- mation causes changes which prevent anything like uniformity. In the explo- sive form, the so-called fulminant variety, it may be below normal ; in all others there is more or less elevation. In some instances, early in the disease, the temperature is not very high, and in others it rises to a high elevation after the chill. When the local inflammations occur it is generally higher. In chil- dren at this stage it is usually from 100° to 101°. The diurnal variation is less than in typhus or typhoid fever. A sudden fall or rise of temperature almost invariably ushers in serious symptoms : in fatal cases it has been found at the time of death to be as high as from 107° to 110°. The pulse in cerebro-spinal fever in children is usually quite rapid ; in adults at the second and third stages of the disease it may be abnormally slow. The difference is owing to the modified nerve-influence which the disease is prone to exert. Complications. — Among the complications observed in this disease may be mentioned pleurisy, pericarditis, endocarditis, parenchymatous degeneration of the liver and kidneys, and intestinal catarrh. " (Edema, hypostatic conges- tion of the lungs, bronchitis, atelectasis, and broncho-pneumonia are not uncommon lesions in cerebro-spinal meningitis" (Welch). Sequelae. — Parotitis ; gangrene ; furuncle ; abscesses ; muscular and mental weakness ; epilepsy ; impaired nerve-power, sometimes amounting to paralysis ; general or special persistent emaciation ; and, in children, effusion following the inflammation of the membranes of the brain sometimes results in chronic hydro- cephalus. Dr. Chas. K. Mills, in a paper read before the Philadelphia Neuro- logical Society in March, 1888, called attention to the occurrence of multiple neuritis as a complication of this disease, and also suggested that multiple neu- ritis might be the only result of the same infection that causes the meningitis. 234 AMERICAN TEXT- BOOK OF DISEASES OF CHILD REX. Diagnosis. — In the earliei* stages, especially in children, it may be mis- taken for scarlet fever. This is true where there is a general erythema or der- matitis. The existence of the epidemic influence of either disease or the pres- ence or absence of severe throat symptoms will greatly assist in the diagnosis. The redness of the skin coming on in epidemic cerebro-spinal fever generally appears later than that of scarlet fever, in which it usually happens in the first twenty-four hours. The eruption is quite transitory, and is not, as a rule, followed by desquamation or itching. The abrupt onset and tke greater activity of the symptoms, the absence of tubercular manifestations elsewhere, the rarity of eruptions and extreme mus- cular contractions, the slow regular course, and the higher temperature would distinguish epidemic cerebro-spinal fever from tubercular meningitis. The absence of exciting causes, the extremeh' faint muscular spasms, and the sen- sitiveness of the skin, all help in distinguishing it from simple or secondary meningitis. The muscular spasms and general and muscular pains usually distinguish this disease from ordinary cases of pneumonia, typhus, and typhoid fever: but in the meningeal forms of these diseases it is extremely difficult to make a diagnosis, though the sudden onset with meningeal symptoms will greatly assist. The earlier symptoms should be studied to find out whether there were evi- dences of pneumonia or any other previous disease. Abdominal symptoms occurring early might suggest typhoid fever. The eruption of typhus is the distinguishing mark in that affection. Rigidity of the muscles, present in cerebro-spinal fever, is absent in the preceding diseases. I have known mis- taken diagnoses to be made in cases of small-pox in the earlier stages. Prognosis. — This is always grave in children, more so than in adults. When we take into consideration the extreme susceptibility of the nervous system of a child, we can readily see how dangerous this disease is during the earlier years of life. Prognosis in adults is a difficult task, for in simple cases sudden grave complications sometimes present themselves later in the disease, and, on the other hand, a case with the severest early symptoms may be followed by speedy convalescence. It is a disease in which it is impossible to estimate the complications which may arise. Unfavorable signs are profound coma ; low typhoid symptoms ; urtemia ; great blood dyscrasia, shown by marked ecchymosis ; continued convulsions and prolonged high fever. Protracted cases are likely to be followed by fatal exhaustion. Treatment. — The types and lesions of the disease are so various that the details of the treatment are exceedingly difficult to formulate to meet all cases. The proph^dactic treatment consists in careful attention to sanitation, as the disease is invited by uncleanliness of person or surroundings ; the same is true of over-crowding. Exposure to heat or cold, and fatigue, either bodily or mental, are favorable to the onset of the disease. Children in a locality where the aff'ection is prevalent should be furnished with fresh, nourishing, and easily- digested food; they should be isolated from the sick, and should have plenty of sleep and pure air. Clothing from about the sick should be destroyed or care- fully disinfected. The weak, old, and nervous should be removed from infected localities. Almost every remedy in the medical category has been tried to abort this disease : bloodletting has had its votaries, and others have highly extolled the virtue of mercurials in the earlier stages ; emetics, again, have been recom- mended, but all have largely been abandoned. The plan pursued by most recent authorities is to treat the disease symptomatically. EPIDEMIC CEREBROSPINAL MENINGITIS. 235 In the first stage we have a congested condition of the meninges of the brain and spinal cord : the indication is to aid in the reduction of the quan- tity of the blood in the meningeal blood-vessels ; first, for the purpose of reliev- ing the symptoms, and, secondly, to reduce the inflammation and modify the inflammatory products. One of the difficulties of administering medicine by the mouth is the common symptom of vomiting, which is sometimes very per- sistent. Venesection should not be practised in children. Some of the German writers use early local bloodletting by wet cups and leeches. Dry cups to draw- blood from the internal congested vessels without removing it from the body are of great value. The extei-nal application of cold to the head by ice, ice-water cloths, cold-water cloths, is useful, and some have used hot baths to the body, hoping to draw blood from the centre to the periphery. Hot mustard foot- baths can be used with advantage to relieve the pain in the head and back. If the stomach should bear it, potassium bromide and ergot may be adminis- tered ; if not, the former may be given by enema, the latter hypodermatically, for the purpose of favorably influencing the capillary congestion. For the pain in the muscles the antipyretics have been used ; phenacetin is probably the safest and best of all. It should be used in small, frequently-repeated doses, and its use should be discontinued if the patient becomes weak or exhausted. A mustard plaster, one part mustard to three of flour, placed over the spine, often relieves the pain in that location, and counter-irritation to the nape of the neck diminishes the pain in the head and relieves the delirium. Care should be taken not to raise a blister, which would se-riously complicate the case. Liniments over the same region — turpentine or chloroform — may be used for similar purpose. Belladonna seems to aff"ord relief to the neuralgic pains and muscular spasms. Dr. J. M. DaCosta highly lauds the use of hyoscine hydro- bromate for the muscular spasms in this disease. For insomnia early in a case chloral may be cautiously used in conjunction with potassium bromide. Chloral sometimes causes cerebral excitement, and when this occurs it should be dis- continued. Opium has always been used with the happiest results. It has been recorded that in some cases large doses of opium are tolerated. The salicylates and gelsemium will allay the pains in the trunk and limbs, but will not relieve the pain in the head. A dark, quiet room should be selected for the patient in any stage ; this is of great importance where there is cerebral excitement. In the second stage the exudate is thrown out ; it may be serous, plastic, or even sero-purulent ; the blood-vessels are dilated and engorged. Absorptive remedies are now to be used. Potassium iodide to produce absorption of the exudate, and oil of turpentine internally have been used late in this stage for the same purpose, with seeming good results. Arsenic and iron are of great use during convalescence to improve the blood. Stimulants, especially for chil- dren, should be used with great caution, as an excess will irritate the brain and excite the circulation in either the first or second stage. Hypophosphites, espe- cially with strychnine, are beneficial during convalescence. Cod-liver oil when digested often produces the happiest results. In the later stages of convales- cence massage is of great importance to stimulate the circulation in the mus- cles and nerves. Electricity is indicated for paralysis or weakness of the nerve- trunks. For the same purpose alternate hot and cold afi'usions to the weakened parts, and exercise, carefully regulated as to time and amount, greatly assist in strengthening the muscles and nerves. EPIDEMIC IXFLUENZA. By CHAS. WARRINGTON EARLE. M. D., Chicago. Influenza is a general infectious disease producing catarrhal difficulties of either the respiratory or gastro-intestinal tract, or painful symptoms referable to the nervous system. In addition to the symptoms thus indicated, it is attended with prostration out of proportion to the apparent involvement of the organs named, and is liable to be followed by sequels which affect pro- foundly the further usefulness and comfort of the unfortunate victim. This disease has been recognized and described in our country for two hundred and fifty years, the first epidemic occurring about 1647. Other epidemics have taken place from time to time, and have been referred to by writers under dif- ferent names ; but the disease, as it affects us particularly, and its history, as we understand it at the present moment, have come to us in the three consecu- tive epidemics of 1890, 1891, and 1892. At the time of writing (January, 1893) only a few sporadic cases have taken place during this year, and they have not been severe. We cannot yet speak of an epidemic of 1893. During the period referred to, great attention has been given to the study of the disease by our profession, and, in certain instances, by governmental authorities. Etiology. — It has not been believed until recently that the causes of this disease are really known. Certain hypothetical causes have been advanced, such as air, contagion, local conditions, general influences, etc. But during the last three or four years very close investigations in regard to its etiology have been made. The reports of the British medical government clearly show that the spread of the disease depends upon human intercourse, and that it spreads no faster than human beings, parcels, or letters can travel. Bacteriological investigations have been carried on with great accuracy during this time. Filatow wrote fully concerning the history and symptoms of the disease under consideration, and Seifert investigated the bacteriological history three or four years ago : but particular investigations have been carried on during the past year in the Berlin Institute by Drs. Pfeiffer, Kitasato, and Canon ; and Sternberg remarks that there is good reason to believe that the bacillus discovered by these investigations is the specific cause of the disease. The following resum^ from Dr. Sisslev of London sives much re^ardincr the etiology of the scourge under discussion : , (1) The first case of influenza in a town is generally a patient who has come from an isolated place. (2) Isolated cases precede the epidemic. (3) Influenza extends along the lines of human intercourse. (4) Isolated persons, such as prisoners and inmates of asylums and con- vents, often escape the disease. (5) The number of those affected in an epidemic increases till a maximum is reached, and then declines, as in the case of other contagious diseases. 236 EPIDEMIC INFLUENZA. 237 There is no doubt that nursing children three or four months of age feel the influence of la grippe. Dr. Townsend of Boston has placed on record a case where the mother had an attack of influenza about the time of her con- finement, and the child in a few hours after birth began to sneeze and had all the symptoms of this infection ; and an English observer records the case of an infant who died on the third day of its life from this disease. It is somewhat difficult to diagnosticate influenza in very young infants, but it is fair to sup- pose that, when the infection is present in the house and parents and nurses are under its influence, if infants present unusual symptoms of fever, exhaus- tion, and the involvement of one of the three systems which are usually select- ed by this infection, the disease is due to the poison of influenza. The exact point at which the infection may gain entrance to the system has probably not been ascertained. That it may enter through either the aliment- ary canal or the lungs there is no doubt, and in all probability these are usually the points of entrance. One observer believes that the conjunctiva is in many instances the structure through which the poison attacks the system. Influenza and Diphtheria. — The marked similarity between the remote eff'ects of the poisons of diphtheria and influenza is very great, and it is quite possible that the pathological findings in influenza may be quite as numerous and signiflcant as we already know they are in diphtheria. We possibly do not know the exact cause of influenza, but we are certainly warranted in assuming that there is a most profound toxic eff"ect in influenza as well as in diphtheria. The depression is profound, the recovery slow and tedious, and the involvement of the nervous system in both diseases is extremely signif- icant. The action of these two poisons upon the heart is someAvhat similar. Every practitioner of experience has noticed the slowness of the pulse and its irregularity, and in some instances death has occurred in such an unexpected manner that we could attribute it to nothing less than degeneration of the heart-muscle. Pathology. — There are but few special post-mortem findings known to this disease which are of value to us as relating to children. Nearly every study has been based upon examinations made in adults, and the records of autopsies made , solely and particularly to find the results of influenza on the tissues of the young are extremely meagre. Ashby and Wright state that '• at the post- mortem no grave lesion is found, but there is usually venous congestion and marked injection of the venous capillaries ; " and Vargas of Barcelona, whose opportunities for seeing many cases profoundly sick with influenza have certainly been very great, after remarking that rapid deaths are usually due to severe attacks aff"ecting the nervous system, says that while Ave cannot state that there is an apoplectic form, in some cases the post-mortem revealed the venous plexus congested, and also cerebral hsemorrhages. The same author also asserts that in cases where the gastro-intestinal symptoms predominated there was tumefaction of Beyer's glands and of the solitary follicles. In 115 references to influenza found in the British Medical Journal oi 1891 and 1892, not one speaks particularly of the pathology as it is found in children. And in the Avorks of Filatow and Ufielmann, both written in 1892, absolutely nothing is said regarding this part of our subject. The special effects of the poison of influenza upon the tissues of the young have yet to be described. Incubation. — This may be only a few days, possibly only a few hours, or, on the contrary, the influence of the poison may be felt for weeks before the active development of the disease. Others who have studied the disease believe that tAvo or three days is the usual time of incubation. 238 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Clinical History. — The disease affects more particularly one of three groups of organs : First, the respiratory and circulatory apparatus ; second, the gastro- intestinal canal; third, the nervous system. Sometimes the infection localizes itself in the respiratory tract, spending its energy there, and the patient will pass through a severe catarrhal bronchitis or a pneumonia with such general prostration as to endanger his life ; or the disease manifests itself as a catarrhal inflammation of the stomach and bowels, with a tendency to collapse on account of the extreme weakness which is induced; or, closely following the severe headache, which indicates that the nervous system is the first to be attacked, have come threatened convulsions and meningitis. We have these organs affected singly, or in some cases a complication involv- ing almost all of them, such as a bronchitis with gastro-intestinal disturbance, or a gastro-intestinal disturbance with great nervous prostration. The invasion is rapid, and the disease is frequently ushered in with a chill followed by delirium and rapidity of pulse. The face in many cases is red from the commencement of the disease, and there is earache, vomiting, and an increase in temperature. The fever is not high in the majority of cases, but occasionally an unusually high temperature is noticed. In a majority of cases, at some time during the disease, the temperature is subnormal, varying from one-half to two degrees below the standard of health. This condition of tem- perature is undoubtedly a result of the action of the poison upon the general nutrition, the imperfect action of the lungs which is present in many cases, and the general depression of the vital forces. There is also loss of weight. This has been particularly brought out by Hansen of Copenhagen, who con- cludes that, while in some cases there is simply a standstill, in many there is an absolute diminution in normal weight. It is fair to conclude that this evidence of waste — in other words, work — represents the conflict between the poison of influenza and its subjects. In some cases this diminution of weight is noticed when there are no other signs of the disease present. And finally there is a very pronounced general weakness never before experienced by the patient, and in no one organ or system of organs is it more noticeable than in the circulatory apparatus. The pulse is usually accelerated, sometimes very rapid, and the heart, in many instances, never regains its strength and vigor. Special Features. — Respiratory Symptoms. — A catarrh of the respiratory organs takes place with great frequency, and in its various phases extends to every part of this system. Sometimes the upper breathing apparatus is attacked first, and the disease rapidly spreads and involves the rest. The eyes are usu- ally red and suffused, and in many cases not only is the middle ear involved, but disease of this organ remains as a sequel for a long time. A general catar- rhal bronchitis is frequently present, and in some instances pneumonia with ah its characteristic symptoms. There is in many cases, early in the disease, an apparent localization of the infection in one or both of the lungs, threatening a pneumonia, but this usually clears up in a very short time, and the disease be- comes diffused throughout both lungs. Very often there may be only a severe and perplexing cough, without any physical signs. Respiration is sometimes slow, and in a few cases breathing for a few seconds has absolutely stopped. These peculiar paroxysms have been repeated several times during the day, and in a few instances life has been preserved during these attacks only by artificial respiration. Thoracic pains are sometimes intense, and call for the external application of anodynes. Circulatory Symptoms. — There is usually from the first a rapidity and weakness of the heart, and syncopal attacks occur in many cases. Depression in the action of this organ and failure in its supply of nerve-force seem entirely EPIDEMIC IXFLUENZA. 239 out of proportion to all otlier symptoms. AVhile in many cases the temjjerature and pulse seem fair, there is an unusual muscular -weakness and a tendency to syncope. I have not noticed organic heart disease, but cyanosis has been present in a few cases, and in many instances palpitation and short breathino' are not only noticed during the active history of the disease, but also inter- minably follow its unfortunate victim. Gastro-intestinal Symptoms. — The tongue is frequently fiabbv and coated, and shows indentations of the teeth, indicating malnutrition. 'The appetite is often entirely absent, and persistent vomiting takes place in manv cases. Herpes labialis is sometimes noticed, as also sordes. Diarrhoea to such an extent as to become exhausting is frequent ; constipation is sometimes present. In some cases the diarrhoea and vomiting are so frequent and persistent, and the child becomes so rapidly collapsed, that if the case occurred in the summer a diagnosis of cholera infantum would undoubtedly be su^aested. As the result of this great withdrawal of fluids from the body, the eves and fontanelles are greatly depressed, and the child becomes restless and rapidlv goes into collapse. Nervous Symptoms. — Extreme irritability and fretfulness are found in the majority of childish patients. Headache and joint and muscular pains are frequent and sometimes intolerable. In many cases there are noticed an indif- ference and a hebetude which closely simulate a typhoid condition. Convul- sions take place in a small percentage of children, and congestion of the brain with drowsiness may be noticed. In one case which came under my observation the child did not close its eyes for four nights. It was not uncon- scious, but indifferent, and wanted to be left alone. In a few cases menino-itis will seem imminent, and the diagnosis will sometimes necessarily be held in abeyance. In some children afflicted with influenza there is developed an obstinacy Avhich is truly remarkable ; they sometimes resist the slightest touch, and refuse all examination on the part of the physician. This peculiarity is regarded by some observers as of diagnostic importance in differentiating from typhoid fever. Temperature. — In addition to what I have already said. I have noticed that the fever may be very high and yet recovery take place. On the other hand, a temperature of 101° to 102.5° F. may persist for a period of two or three months. In these cases I have suspected and have repeatedly examined for evidence of tuberculosis, and have not found it, the patient finally makino- a good recovery after this long period of sickness. In general, we mav make the statement that the temperature is more irregular in influenza than in any other disease. Complications and Sequelse. — These are numerous and varied, and attack nearly every function and organ of the body. Glandular enlargements are frequent. Inflammation of the parotid gland may take place. iVbscess of the antrum and inflammation of the connective tissue of the neck have been noticed. Tuberculosis and tubercular meningitis may follow in a few cases. Conjunc- tivitis may remain, and catarrhal inflammation of the middle ear, resultiuc^ often in perforation and profuse discharge, will be noticed. At times this involvement of the middle ear, while always a serious complication, may even threaten the life of the patient. Diseases of the skin are sometimes noticed, such as erythema, herpes, and urticaria. Among the more general diseases that have been observed are rheumatism, chorea, nephritis, and periostitis. Children having a tendency to rickets have been known to develop the disease after having had an attack of influenza. Among the complications which I have noticed, and which I have not seen 240 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. recorded, is purpura. Of this I have seen four cases, all in young people, and attended with extreme weakness and with evidence of more or. less blood- change. As is not unusual in adults, acute mania has been observed to follow the disease occasionally in children, but generally ends in complete recovery. Dr. Julius Althus, in an extensive article on mental affections after influenza, gives cases illustrating neurasthenia, hypochondi'iasis, melancholia, delirium from inanition, homicidal tendencies, and general parah'sis. He believes that the psychoses observed after epidemic influenza are far greater than those after any other infectious disease. Diagnosis. — From the rapidity with which it seizes the patient, influenza might be mistaken for sunstroke, an acute poisoning, or malignant malaria. It can be confounded with all diseases of the respiratory apparatus, with typhoid fever, and with meningitis. From a simple catarrh, influenza will be distinguished by the fact that it is epidemic, and that there is greater prostration, which continues for a longer period of time, than in the first-named disease. The temperature is also higher, and there is a tendency to catarrhal difliculties — at first local, but rapidly spreading to other portions of the body. A mild catarrh, with severe neuralgia and with unusual pain in the limbs, should be diagnosticated as influenza if this disease be prevalent. The same may be said in regard to an irri- table stomach, Avith diarrhoea and an unusual prostration. This in a time of epidemic should certainly be classed as influenza. From pneumonia and bron- chitis, simple or capillary, we differentiate influenza by the absence of the usual physical signs, although at the commencement of the grippe in many cases there will be symptoms of pneumonia, and it seems as if localization had indeed taken place : but frequently in a few hours this becomes diffused, and a general bronchitis with the excruciating pain and prostration belonging to influenza is detected. From typhoid fever influenza is differentiated by the fact that no rose-spots appear and no enlarged spleen is found, and the catarrhal condition, more par- ticularly in the respiratory tract, predominates over all other symptoms. If diarrhoea exists in influenza, it will be noticed that a cough and a catarrhal state of the air-passages has preceded its development. The fever in influenza is irregular ; in typhoid it is so regular and constant that it almost makes its own diagnosis. It is not usual to notice the apathetic facial expression that we have in typhoid. The face, however, is usually flushed in influenza — more frequently pale in the continued fever. There are no rose-spots in influenza, no tenderness and surwling in the risht inguinal recrion. From meningitis influenza can usually be diagnosticated by careful obser- vation of the eye and by the want of the rigidity of the muscles which we find in meningitis. The disease of the brain usually develops rapidly, and if death does not take place it disappears quickly. I must, however, say that the differentiation of meningitis from certain forms of la grippe is attended with great trouble, and a diagnosis must in some cases be withheld. When the fever persists after all other symptoms of influenza have subsided, and there is a cough with gradual emaciation, the closest care must be taken that a tuber- cular disease does not come in. Particular attention should be given to nutri- tion, and every means should be taken to diagnosticate the disease earlv. Prognosis and Mortality. — In this connection an interesting topic might be discussetl as to whether one attack of influenza protects from subsequent attacks. I do not think that this question at present can be fully answered, but the general statement can be made that many families particularly afilicted EPIDEMIC INFLUENZA. 241 in 1889 did not develop the disease in 1890 or 1891. There are those who are immune from the disease, and others in whom it has developed three con- secutive years. The mortality is different in different epidemics, and the character of the epidemic must be considered, as in all other infectious and contagious diseases. In some epidemics children are particularly liable to contract the disease, Avhile in others adults seem to be selected. And again in a more general epidemic it has been noticed, as I can personally attest, that children often are not attacked until the disease has prevailed for some time. When the attack is moderately severe, I regard it a dangerous malady for a child, particularly if he has anaemia or any vicious constitutional tendencies. Death has taken place in twenty-four hours. It may come from almost every complication, but, in the main, exhaustion and bad nutrition bring about the fatal result. Death may come with such rapidity that in summer insolation is suggested, and at other times malignant malaria. In the fulminant variety with rapid death, the severe symptoms will be referable to the nervous system, while throughout the entire history of other cases the poison selects the respiratory or gastro-intestinal tract, and death comes as it does in those diseases when not complicated with influenza. But it must be remembered that there is always a tendency to col- lapse and a prostration out of proportion to other symptoms. The length of time consumed in convalescence from this disease is wonder- ful. The pains and general weakness do not dis'appear for weeks ; and I may add that many of the sequelae remain for years, and not only produce suffer- ing, but shorten the life of the individual. Treatment. — I have no particular remedy or combination of remedies to suggest. I think, however, that care should be taken to prevent the contagious element from spreading and gaining a hold on the community, and, in view of the great mortality and the immense money loss which this disease causes, it appears to' me that the time will come when it will be regarded as the duty of all municipal authorities to assume such control of the disease as science suggests. Let the people undeistand that it is a contagious disease, and instruct them how to prevent its spreading by contact. All handkerchiefs and cloths used by the patient must be immersed in some antiseptic fluid, and all cuspidors and articles of furniture which come in contact with the germs of the disease should be carefully disinfected. A generous diet must be insisted upon, some stimulation, and a conservation of all the strength of the patient observed from the outstart. For the general pain which pervades the entire system, which sometimes is the first and most prominent symptom, nothing has given me such good results as phenacetin and salicylate of sodium. The catarrh of the respiratory tract which speedily prostrates young children should be early treated with stimu- lants, including the ammonia preparations and the ordinary expectorants. The gastro-intestinal catarrh must not be neglected, but should receive attention from the first. It is a clinical fact, which must have been observed by many, that in some of the neglected cases there is just as profound and general col- lapse from the copious diarrhoeal discharges and vomiting, which we sometimes see in this form of the disease, as from those which take place in severe cases of cholera infantum. They should, then, have attention from the very first. For the extreme fatigue and depression not only alcoholic stimulants, but the effervescing waters with quinine, should be administered. If the stomach is particularly irritable, let the quinine be administered by inunction or by the rectum. Children take eagerly and with good results whipped egg-albumin 16 242 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. ■with sterilized water and a little stimulant and sugar. Champagne is excel- lent for the depression which is so evident among these little people. When there is great prostration following the involvement of any of the three systems we have mentioned, the carbonate of ammonium, camphor, and musk, fortified by the conjoint use of digitalis and nux vomica, are indicated. When the patient begins to pass out from the more painful and acute mani- festations of the disease, in addition to a generous diet a tonic composed of the compound syrup of hypophosphites, extract of malt, and pepsin cordial, equal parts, with a very small amount of elixir of bark, iron, and strychnine, acts efficiently. .:»: ERYSIPELAS. By FREDERICK A. PACKARD, M. D., Philadelphia. Erysipelas is an acute, specific, contagious, inflammatory disease of skin and mucous membranes, accompanied by marked general symptoms, and cha- racterized by peculiar local lesions at the seat of inoculation, by its tendency to spread, and by the presence in the affected area of a micrococcus that is capable of reproducing the disease in other individuals. The Avord " erysipelas " is probably derived from ipudpo^, red, and niXla, 8lun. Numerous qualifying words have been used to signify the point of involvement, the course of the disease, the appearances presented by the local lesion, the age at which the disease occurs, etc. The terms "traumatic " and " idiopathic " have been used to distinguish cases wherein there is or is not an antecedent obvious wound of the skin at the seat of the local lesion. No qualifying words should be used as implying an essential difference in the pro- cess, as it is a disease sui generis, no matter under what circumstances it may occur. History.-=-Erysipelas has been known from the time of Hippocrates, but the descriptions of the disease given by most writers prior to those of the last century shoAV that many diverse diseases were included under this name. When humoral pathology occupied men's attention, this, in common with many other maladies, was supposed to be the outward expression of morbid humors in the body. At a later date it was looked upon as a simple dermatitis ; still later, as a simple lymphangitis. The contagiousness of the disease was pointed out by Lorry in 1777. A microbic origin was first suspected by Martin in 1865. The question of priority in demonstrating this origin is still a matter of dispute. Between 1868 and 1870, Nepveu and Hueter described the occur- rence of microscopic organisms in connection with the disease. It need only be stated here that the description given by Nepveu corresponds more closely than does that of Hueter to the micro-organism now established as the cause of the disease. Since 1870 many observers have studied the disease from a bacteriological aspect, but it is especially to Fehleisen that we owe our present knowledge of the life-history and etiological role of the micrococcus described by him in 1882. Etiology. — The disease is limited in its occurrence to no part of the civil- ized world, but its favorite habitat is the temperate zone. It but rarely occurs in the tropics, being less rare in regions far removed from the equator. In Greenland, for example, occasional widespread epidemics have occurred. The predisposing effect of season can be readily seen by the accompanying chart (Fig. 1). It will there be found that by far the greater number of fatal cases in Philadelphia occur during the latter part of the first and the early portion of the second quarter of the year ; that is, during the early spring months. Allen analyzed 566 cases applying for treatment, and obtained practically the same result, 243 244 AJUJBICAX TEXT-BOOK OF DISEASES OF CHILDBEN. It appears to be most prevalent among the poorer classes. This may be due to several causes — the greater liability to injury, frequency of chronic Fig. 1. ir-. QUARTER 2".° QUARTER 3"?

The question of age as a predisposing factor is difficult to determine, as only fatal cases appear in the reports of boards of health. Of 12,556 fatal cases of the disease in England between the A^ears 1862 and 1868, there occurred under one year of age 31 per cent. ; under five years, 5.9 per cent. ; under fifteen years, 2,9 per cent. ; under twenty-five years, 4.2 per cent. ; under forty-five years, 12.4 per cent. ; under sixty-five years, 20.9 per cent. ; above eighty-five years, 1.4 per cent. In Philadelphia, during the period between 1874 and 1891, there occurred 1253 deaths from erysipelas. Of these, 380 were in children under one year of age, 35 betAveen one and two, 23 between two and five, 25 betAveen five and ten, 6 between ten and fifteen, the remain- ing 784 cases occurring in those past the latter age. All that can be said, therefore, is that no age is exempt. The large number of fatal cases occurring in the first year of life may be due to the almost uniform fatality of the disease during the early part of that period, and cannot be taken as an index of the actual number of cases occurringr in infants. EB YSIPELAS. 245 What part filth and defective drainage may play in its production has not been definitely settled. In the older hospitals of Europe frequent epidemics have occurred ; but it is not alone in these that erysipelas appears, new and apparently sanitary institutions being also the scene of its occun-ence. A well-known and oft-quoted instance of the eff"ect of polluted air is that which occurred in the Middlesex Hospital, where a defective drain was on two occasions the apparent cause of an outbreak of the disease, starting in the bed nearest to its position in the wall. It is said to be frequent in the immediate neighborhood of badly-kept stables. The most important etiological factor is contagion. The contagious principle has but a limited area of influence, as is shown by some of the histories of local epidemics within hospital wards, wherein patients upon one side of a ward have been affected seriatim on both the right and left of the individual first attacked. Those in attendance upon a case are apt to contract the disease. One attack seems rather to predispose to, than to protect against, a recurrence, due probably to the fact that some breach of the surface produced by a chronic affection admits the poison. The contagious principle is the st7'eptococcus erysipelatis. Although pre- vious investigators had discovered micrococci in the local lesion, the most careful and conclusive work upon the subject was performed by Fehleisen, hence the micro-organism is frequently spoken of as the streptococcus of Fehleisen. By him it was found in the lymphatic vessels and spaces of the skin and subcu- taneous cellular tissue, and in the superficial layers of the corium. It occurs as a single cell or in the form of diplococci or chains of various length. The individual cell measures about 0.3// in diameter. It is readily cultivated upon gelatin and blood-serum, where the colonies form as dull-white, round points, closely marginated or fusing at points of contact. It grows well at the tem- perature of the human body, is facultatively aerobic, and develops well m vacuo. Not only has the inoculation of pure cultures been successfully practised upon animals, but the disease has been inoculated upon human beings as a therapeutic measure. In order that the parasite may gain access to the lymph-spaces, it is essen- tial that some breach of the surface should exist. This means of entry may be supplied by some wound accidentally received or purposely inflicted, by the unhealed navel of the new-born, scarifications made for purposes of vacci- nation, the local lesion of vaccinia, the ulcers of varicella, solutions of continuity produced by eczema, intertrigo, ecthyma, or pemphigus, or by ulcers resulting from chronic inflammation of the mucous membranes of the mouth or upper air-passages. It is owing to the frequency of lesions at the points of union of skin and raucous membrane that the local manifestations frequently begin at those situations. Pathological Anatomy. — After death the body-heat is maintained for a long time, and, according to Eulenburg, there is a post-mortem rise of tempera- ture to a point .9° C. (1.5° F.) above that observed before death. At the seat of the local lesion the vivid color gives place to a mere yellow- ish discoloration, and much of the swelling observed during life disappears. When the skin is incised there exudes a varying quantity of more or less discolored serum. The skin and subcutaneous tissue are somewhat thickened and cannot be readily separated. Microscopical examination of the affected skin shows that beyond the peripheral margin there are numbers of micrococci in the lymphatic vessels. As sections are made from without inward, the greatest histological changes are seen at the visible margin of the patch, where there are much serous infiltration separating the cells, and infiltration by round 246 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. and wandering cells, many micrococci being contained in the latter. From this point the alterations progressively diminish as the part earliest attacked is reached, until complete restitutio ad integrum is found to have occurred. The hair-shafts are unaltered, but there is serous and cellular infiltration of the root-sheath, and micrococci may be found in the space between the latter and the root. In lately-developed vesicles upon the surface no micro-organisms are to be found, but in those of longer existence various forms abound. In phleg- monous erysipelas there is an admixture of the staphylococcus pyogenes with the streptococcus erysipelatis. The nmcous membranes that are affected show the same appearance as does the skin, save for the normal structural differences in the tissue. Attackinor the larynx, the disease produces marked swelling in the parts around the glottis. (Edema of the rima glottidis may be present. The trachea and bronchi may be of a brillant red color, with paler areas corresponding to the cartilaginous rings. Three forms of pulmonary lesion may be found : (1) an accidental croupous pneumonia, with the ordinary appearances of that lesion ; (2) intense congestion, either general or limited to diseased branches of the bronchial tree, with scattered areas of red or gray hepatization Avithin the congested area ; (8) an acute infective interstitial pneumonia from bacterial embolism, with subsequent dissemination of micrococci in the interlobular connective tissue. In cases where the disease has spread from the air-passages the alveoli contain large numbers of leucocytes and many micrococci, instead of the fibrin and epithelial cells seen in croupous and catarrhal pneumonia. Inflammation of the pleura may be found from extension of the disease through the chest-wall or as secondary to subpleural pulmonary lesions. The pleural cavity may contain serous or purulent exudate. The streptococcus has been found m pleural exudate. Suppurative anterior mediastinitis has been observed. Pericarditis is rarely seen, but endocarditis, affecting chiefly the free borders or the whole of a leaflet of the valves of the left side, is occasionally present. Granular degeneration of the myocardium also occurs, due doubtless to the elevation of temperature. The endothelium of the blood-vessels has been found to be swollen, granular, and with indistinct nuclei. Tutschek reports a case of thrombosis of the abdominal aorta. The streptococcus has been found in the blood of the skin, subcutaneous adipose tissue, and in the capillaries of the lungs, liver, spleen, and kidneys. The stomach may exhibit marked engorgement of its vessels, the intestinal tract patchy redness. Multiple minute duodenal ulcers have been seen. In the lai'ge intestine the typical erysipelatous local lesions may be found in cases where the disease has spread from the perineum through the anus to the rectal mucous membrane. The liver may be large and congested in rapidly fatal cases; in those of longer duration it is more often pale, soft, and the seat of fattv deoreneration. Many observers have found the streptococcus within the organ. By most authors the spleen is said to be increased in volume, as would be expected from the frequency of its enlargement during life in non-fatal cases ; but Denned found it small, soft, and hyperaemic. Peritonitis is comparatively rarely found, most instances of its occurrence being in the new-born, where the abdominal wall has been the seat of the primary process. In spite of the prominence of cerebral symptoms during life, there are but seldom found any marked structural alterations within the cranium. The membranes may be anaemic or their vessels intensely engorged with blood. Actual meningitis is rarely seen. An instance is reported by Osier of menin- ERYSIPELAS. 24T gitis and thrombosis of the lateral sinus in a fatal case of facial erysipelas wherein the process could be traced along the trunk of the fifth cranial nerve. From the frequent presence of albuminuria it is to be expected that in fatal cases the kidneys would shoAv structural alterations. In five cases examined by Denuce these organs showed nephritis in degrees varying with the duration of the case. Langer has reported a fatal case of erysipelas of the scalp occurring in a seven-weeks-old boy, and complicated by hsemoglobinuria, wherein the kidneys showed infarcts and miliary abscesses. In the articular inflammatory exudate that sometimes occurs Schliller found the streptococcus. Symptoms. — In spite of the fact that in six cases purposely inoculated by Fehleisen the initial chill occurred in from fifteen to ninety-one hours, the incubation for cases accidentally inoculated may be reckoned as requiring a period of from three to seven days. The onset may be sudden, the first symptom being a chill with rigor. In other cases feelings of languor and vague discomfort in the part that later becomes the seat of the local lesion may precede the occurrence of chill. In young children the occurrence of an initial convulsion is not infrequent. The attack may begin with severe inflammation of the upper air-passages or throat, the skin lesion not appearing for twenty-four or thirty-six hours after the first signs of illness. The temperature rises rapidly to 102°, 103°, or even 105° F. The aff"ected area soon becomes the seat of burning, smarting pain. The local appearances at this time may merely amount to slight redness and glossiness. In a short time there is slight elevation of this reddened area above the sur- rounding healthy surface, the color deepens in shade, and there are pitting and pain upon pressure. The color is readily dispelled by pressure, but quickly returns upon the withdrawal of the finger. The pain becomes more intense, and there is a sensation of stinging and stretching in the aifected part. The tongue is coated, there is anorexia, thirst may be marked, varying degrees of cephalalgia are present, while nausea is a frequent source of complaint. Vomit- ing is not frequent in cases of ordinary severity. At this stage the pulse is usually full, bounding, and rapid. Upon the second day the temperature-chart shows a slight morning remission. The redness and swelling extend from the original site to cover a larger area ; the eyes may be invisible from swelling of the lids, the ears swollen and distorted, and the lips thickened. Cephalalgia becomes intense, especially if the scalp be invaded ; insomnia and delirium frequently appear. Albuminuria, with a copious deposit of amorphous urates, will usually be found after the first few days. On the second or third day the local appearances of the part first attacked reach their highest degree of devel- opment. Thereafter the redness and swelling of that part subside. Meanwhile the local process may have steadily advanced from the point of its original appearance until large areas of skin are involved. When extension ceases the temperature rapidly falls, the pulse becomes less bounding and its frequency diminishes, pain lessens, the associated symptoms rapidly subside, and the patient enters upon convalescence. During convalescence the affected skin has a faint yellowish discoloration and is the seat of desquamation, the epidermis separating in branny scales or in large flakes, and in cases where the scalp has been invaded the hair falls. Albuminuria may persist in lessening degree for several days after the cessation of other symptoms. Important variations from this ordinary type occur and require separate consideration. Erysipelas of the new-born begins either at the navel or at a point nearer to the symphysis pubis. Thence extension rapidly occurs until the skin of the whole abdomen, that of the extremities, or even larger portions of surface, may 248 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. be involved. The infant exhibits extreme restlessness and has high fever, may vomit frequently, and soon passes into an asthenic condition that speedily ends in death. In other cases the process extends along the still patulous umbilical vein, reaches the liver, and may lead to fatal peritonitis. After the early days of infancy are passed the disease shows the same characters in children as in adults. Where the mouth, tonsils, j^harynx, or nares are primarily attacked, the local appearances are those of an intense inflammation of the part affected, but swelling is more marked than usually occurs with ordinary inflammation, and the tendency to spread to adjacent structures and the skin is a peculiarity of great diagnostic importance. From the nares it may extend to the lachrymal duct and attack the skin near the internal canthus. From the upper air- passages the process may extend to the bronchi or to the lungs, producing the symptoms and physical signs of an intense bronchitis or pneumonia. In the primarily laryngeal form hoarseness begins early, and may be rapidly followed by symptoms of suffocation due to the intense swelling of the mucous membrane. The eruption exhibits certain peculiarities Avorthy of further study. Exten- sion usualh" takes place most rapidly in one direction, but not in an even line, as flame-like tongues of redness frequently jut out in advance. The area of redness and swelling is bounded by an abrupt fall to the level of the healthy surface. Extension from the face usually occurs upward, reaching the hairy scalp or even passing backward to the nape of the neck or to the trunk. From the trunk it may spread to the extremities or head, and vice versd. One striking peculiarity of the eruption is its liability to terminate at natural boundaries — the borders of the hairy scalp, the various folds of the face, the groin. Where the underlying bone is close to the surface the eruption is fre- quently absent ; thus the chin may be spared, while the rest of the face is much swollen. Conversely, where the skin is but loosely attached to under- lying structures — as in the scrotum, labia majora, and eyelids — sAvelling is very marked, and gangrene may occur from interference with the circulation. Besides redness and SAvelling, other appearances are usually present in the affected area of skin. Vesicles, or even bullae with clear or muddy contents, are apt to form. Pustules are rarely seen, but in some regions with resisting skin a verrucose appearance may be presented from cellular infiltration. INIinute points or quite extensive areas of gangrene may occur. The bursting of the vesicles and bullne causes the formation of yellowish or brownish crusts. After the active process in a part has subsided the surface is covered with bran-like scales, large flakes of detached epithelium, and crusts of varied hue. The hair may fall very rapidly, leaving the scalp bare, smooth, and shining. The temperature-curve follows quite accurately the extension and subsidence of the local process. After the latter has entirely subsided there may remain an elevated temperature, OAving to the presence of irritation or actual inflam- mation of various organs. Cavafy has reported five cases, and I have seen one, of erysipelas of the face Avithout pyrexia. Not only may the urine contain albumin and an excess of urates, but hya- line and granular tube-casts may also be present. These disappear after the cessation of the disease in the majority of cases. Their presence may be the evidence of the rekindling of a pre-existing disease of the kidneys, in which case they Avill usually persist or even increase as time passes. Complications and Sequelae. — The lung is perhaps the most frequent seat of complication in erysipelas. Pneumonia of the ordinary type is of not ERYSIPELAS. 249 infrequent occurrence, or the specific process may attack the lung-structure. Pleurisy (with or without efiusion), empyema, peri- and endo-carditis at times occur. Pleurisy occurred twice in eight cases purposely inoculated by Fehleisen. Previously-existing nephritis is apt to be awakened into activity, and uraemia may be the immediate cause of death. Haemoglobinuria may be a compli- cation, as in the case reported by Joseph Langer. In facial erysipelas suppu- rative inflammation of the orbital connective tissue is much to be dreaded, and is frequently fatal from extension to the cerebral meninges through the optic foramen or sphenoidal fissure. Amblyopia or complete amaurosis may result from pressure upon the optic nerve or vessels of the eyeball. Obstinate vomit- ing is at times a serious complication. Diarrhoea frequently occurs, and the stools may contain blood. After the active signs of disease have disappeared superficial abscesses frequently form. Erysipelas is, according to Gowers, rarely followed by paral^^sis. Optic neuritis, optic atrophy, or thrombosis of the retinal vessels may follow com- pression of the optic nerve and ophthalmic blood-vessels in cases of orbital cellulitis. Amblyopia may be due to retinal haemorrhages, detachment of the retina, or opacities in the vitreous. In 9209 cases of adventitious deafness analyzed by W. B. Post, erysipelas was the alleged cause in 36. Diagnosis. — In ordinary cases the diagnosis is readily made. The sudden onset of marked constitutional symptoms coincidently with or rapidly followed by the red, elevated, painful lesion of the skin, the peculiar qualities of the latter, and, in particular, the tendency to spread, sufficiently stamp the disease. When the mucous membranes are first attacked it may be impossible to make a positive diagnosis until the skin becomes affected ; but here also the rapid and continuous spread of the disease along the mucous membrane, together with the intense swelling and brilliant redness of the part, should suggest the erysipelatous nature of the inflammation. Where the poison has entered through the lesions produced by eczema of the hairy scalp, such as is so frequently seen in the neglected children of the poor, the. cause of the constitutional symptoms may be only discovered upon the extension of the local process to the forehead, neck, or ears. From simple erythema the diagnosis is made by the tense swelling, the sharply-defined border, the more marked ambulatory character of the lesion, the fever, and other marked systemic symptoms of erysipelas. From angeio-neurotic oedema this affection differs in all points save the fact of the presence of swelling. From ordinary urticaria it may be distinguished by the rapid appearance and reappearance of "hives," and by the occurrence of the eruption simultaneously in different portions of the body. The local appearances of acne rosacea sometimes closely resemble those of erysipelas, but the clinical history, the rapidity of extension, and the constitutional symptoms of the latter disease clearly diff"erentiate the two affections. From malignant oedema the diagnosis must be made by the method of spreading and the local appearances peculiar to the two diseases. Malignant oedema more frequently occurs at points where the skin is particularly thin than does erysipelas. Prognosis. — In uncomplicated cases the usual result is in complete and rapid cure. In the new-born (that is to say, in those under the age of fifteen days) the disease is practically always fatal, owing in part to the lack of resist- ing power in those so young, in part to the ease with which extension occurs, and in great part to the liability to the occurrence of phlebitis of the umbilical vein and of peritonitis. In older children complete cure usually results. 250 AJI£BICAX TEXT-BOOK OF DISEASES OF CHILDBED. Among especially unfavorable occurrences may be mentioned suppuration in the orbital space, gangrene, signs of inflammation of the lung, pericardium, or endocardium. When optic neuritis, optic atrophy, or thrombosis of the retinal arteries occurs, the prognosis as to return of vision is unfavorable. Permanent baldness but seldom results, in spite of the complete alopecia that often is present immediately after the attack. Treatment. — In this disease the same rules in regard to isolation should be followed as in other contagious diseases, save only in the degree to which it should be practised. Occurring in the medical wards of a hospital, it may not attack other individuals, providing that the beds are in not too close appo- sition. The contagiousness of erysipelas is not sufficient to warrant the exclu- sion of cases from medical wards that are properly separated from the surgical and obstetrical departments. It is sufficient that the patient be so placed that he may be surrounded by those having no breach of cutaneous or mucous sur- faces. In surgical and obstetrical wards cases of en'sipelas should be excluded, and the occurrence of an attack should be the signal for immediate isolation. No safer means for the prevention of the disease exists than the use of thoroughly antiseptic methods as regards the wards, the operating-room and its appurtenances, the persons of operators and assistants, and the dressings employed. Where attacks recur in an individual any existing lesion that may give entrance to the poison should receive careful and prompt treatment. In the case of a self-limited disease, and one that rapidly subsides without warning, deductions as to the efficacy of any particular line of treatment must be most carefully drawn. The methods employed in erysipelas are too numer- ous to be here enumerated ; suffice it to mention a few of those that have stood the test of prolonged use by various observers. A mercurial purgative is advantageous in the early stages and before the institution of any line of treatment. But two drugs deserve mention as hav- ing any eifect upon the course of the disease — tincture of the chloride of iron and jaborandi. After prolonged trial the first of these seems to have some influence in modifying the severity and shortening the course of the attack. It is best given in large doses, 5 to 15 drops, every three or four hours accord- ing to the age of the child. Under its use there is usually found a rapid cessa- tion of extension of the local process and subsidence of the general symptoms. Jaborandi, or its alkaloid pilocarpine, was first recommended by DaCosta, and has had numerous advocates since the announcement of its value in erysipelas. In children, however, it must be given with caution and in doses carefully graduated to the age of the child, the object being to give by hypodermic injection an initial dose of pilocarpine sufficient to produce a pronounced sweat, and thereafter to give every four hours doses of the fluid extract of jaborandi sufficient to maintain a gentle diaphoresis. In adults the method is decidedly beneficial, but in children its use requires caution and careful watch- ing by an intelligent attendant. The almost purely mechanical rules that govern the extension and limita- tion of the local process have led to various attempts to substitute artificial boundaries for those of nature. For this end pressure applied in advance of the lesion has been extensively employed by means of tight bandages of elastic material, by the application of strips of adhesive plaster, and by collodion. In many situations no form of pressure is practicable save that by collodion ; but the depth to which the constriction by collodion reaches is too slight to offer any obstacle to the spread of the process. Where the other methods are avail- able the application of constricting bandages sufficiently tight to accomplish the object in view is apt to be too painful for their long continuance. As, EB YSIPELAS. 251 however, this does not preclude the employment of other methods of treat- ment, it should be tried wherever practicable. Attempts have been made to stay the spread of this specific inflammation by the production of simple inflammatory exudation. For this purpose incis- ions were made or the solid stick of nitrate of silver was applied to the skin beyond the afi"ected area. Scarification of the healthy skin beyond the edge of the patch has been, and is still, used by some for the same purpose. Hueter first introduced the injection of 2 per cent, carbolic-acid solution under the skin threatened with attack. In some cases it seems to have limited the pro- cess, but the method is not always successful. It is, however, rational. As applications to the diseased area many materials have been recommended, such as flour, lycopodium, or other bland powders, white paint, lead-water and laudanum, cold water, vinegar and water, turpentine, and tar. These are now but seldom used, except white paint and lead-water and laudanum. The exclu- sion of air of itself seems to relieve much of the discomfort and pain. On this account any emollient application is agreeable. To the fatty base various sub- stances may be added. One of the most agreeable is the hydrochlorate of cocaine in the proportion of 16 grains to the ounce. This usually relieves pain very markedly. Resorcin in the strength of a drachm to the ounce may be used. Koch recommends the application, by means of a bristle-brush, of a mixture of creolin 1 part, iodoform 4 parts, and lanolin 10 parts. Spraying of the aS'ected surface with a solution of corrosive sublimate has been recom- mended, but greater relief of discomfort, with more likelihood of reaching the deeper parts, can be obtained by the use of constant applications of emollient preparations. The diet should be nourishing and easily digestible. Milk should consti- tute the basis during the acute stage of the disease, but eggs, broths, and soft milk foods may be given, except when fever is so great as to interfere with the process of digestion. In all cases occurring among the debilitated, and par- ticularly in very young children, stimulants will be almost invariably required. The amount to be given depends upon the age and condition of the patient. For extreme elevation of temperature the application of cold externally by means of sponging with cool or cold Avater, the wet pack, or the cool bath should be employed. Where the hyperpyrexia resists these measures, or where they cannot be properly applied, antipyrine, acetanilid, or, better still, phena- cetin, may be cautiously tried. The drugs mentioned should only be employed with extreme care and in minimum eifectual doses. For delirium bromide of potassium or sodium may be given, either by mouth or rectum. Cold applications to the head may be sufficient to mode- rate the symptom. Opiates are to be used only as a last resource and with great circumspection, not only because of the danger attending their use in childhood, but also because of the liability to insufficiency or actual inflam- mation of the kidneys in this disease. Impending suffocation from swelling of the rima glottidis may require tra- cheotomy. Any purulent collections that may form should be promptly released by the knife. After the subsidence of the disease tonics with hsematinics will be required. The alopecia that occurs in some cases usually requires no special treatment, but friction of the scalp and the use of cantharidal preparations will hasten the growth of the hair. Therapeutic Use. — A few words must be added regarding the use of ery- sipelas as a therapeutic measure. For many years back there are to be found reports of cases wherein an intercurrent attack of erysipelas was followed by 252 A3rEBICAN TEXT-BOOK OF DISEASES OF CHILDREN. an amelioration or complete subsidence of the primary affection. The fre- quency of this phenomenon led to the intentional inoculation of erysipelas for the cure of various affections that Avere resistant to other measures of treatment, were inaccessible to the surgeon's knife, or whose existence was incompatible Avitli that of erysipelas. Among the aff"ections alleged to have been cured by such an attack of erysipelas or by the intentional inoculation of the streptococcus of Fehleisen may be mentioned various lymphosarcomata, epitheliomata, lupus, and various other chronic superficial ulcerations, keloid, neuralgia, various psychoses, acute polyarthritis, and pulmonary tuberculosis. The antagonism between erysipelas and diphtheria has led to the inoculation of the former upon the latter disease. While many favorable reports as to the action of erysipelas in the reduction or complete removal of sarcomatous and carcinomatous tumors are to be found, there are others where either no result has been obtained or where recurrence of the growth has taken place, or even death has been brought about by the erysipelatous attack. The cases of neuroses and neuralgia that are found to have been relieved by an attack of the disease can be duplicated by those wherein cure has resulted after many diff"erent mental or physical impressions. In regard to the superficial skin lesions, the favorable action of erysipelas may be explained by the local influence of the inflammation produced as part of the latter. As to the favorable result in a case of pulmonary tuberculosis reported by Chelmonsky, it can only be said that further evidence must be brought forward before any definite curative influence of erysipelas upon this pulmonary lesion can be acknowledged. Attractive as is the theory of the antagonistic action of the bacterial products in one disease upon its own micro-organisms or upon those of another malady, it seems as yet unjustifiable to purposely add to the existing aff'ection a disease which, while usually ending in recovery, not only may of itself prove fatal, but which is often observed as the final and fatal complication of many long- standing cases of incurable disease. CHOLERA ASIATIC!. By EDWARD O. SHAKESPEARE, A. M., M. D., PHrLADELPHIA. This disease woukl be most properly designated as cJiolera infectiosa epi- demica, for in this term a definite idea of its chief characteristic and of its most marked tendency would be included. Cholera Asiatica is an exceedingly dangerous specific human disorder, pri- marily of the digestive tract, occasioned directly by the ingestion, entrance into the small intestine, and exuberant multiplication there of special minute vege- table parasites, the spirilla cholerje AsiatictB, the so-called "comma bacilli" of Koch. The special poison elaborated by the growth of the parasites in the intestines attacks the epithelial lining of the latter, ultimately reaches the cir- culation and the nerve-centres, and causes the complex phenomena which cha- racterize the disease. The intestinal contents, the vomit, and the stools of the attacked contain these specific pai-asites in enormous numbers, and they ai'e infectious so long as the latter retain their vitality and power of reproduction ; so long as their infectious quality persists they are capable, under favorable circumstances, of causing an attack of the same disorder in another exjjosed, susceptible person, and of giving rise to a local or widespread epidemic of the same disease. For the latter reason does the danger to the public always outweigh in magnitude even that to the individual attacked. Cholera Asiatica is endemic in the lower two-thirds of the presidency of Bengal, roughly corresponding to the delta of the Ganges and the Brahma- pootra ; it becomes epidemic in other parts of Hindostan and of the world only periodically, after more or less irregular intervals of entire absence. During the intervals of epidemics, except as scattered cases shortly preceding or fol- lowing such visitations, and as an essential part of the latter, it does not exist outside the endemic area : it has no more affiliation with or relation to our somewhat common so-called "summer cholera — otherwise termed cholera nostras, cholera morbus — than it has with some acute attacks due to arsenical poison- ing, to ptomaine-poisoning from ingestion of decomposed food, or to acute per- nicious malaria, or to still other very different disorders, all of which, never- theless, not infrequently present very similar symptoms and terminations. Etiolog-y. — iilthough abounding filth of the surroundings — that is, of the district or the locality, of the domicile, of the home-life, and of personal habits — favors infection and the subsequent development of an individual attack, and the initiation, continuance, and spread of an epidemic of cholera Asiatica, neither a personal seizure nor an epidemic outside that endemic area which is the natural home of this disease can occur (not even when the person or population wallow in every sort of reeking abomination), unless the special infection be first introduced. In other words, no amount of filth is capable of producing a spontaneous generation of the specific infection Avhich is the active 253 254 A 3f ERIC AN TEXT-BOOK OF DISEASES OF CHILDREN. cause of this disease ; nor, without the activity of this specific cause, is any other agency or influence capable of producing the disease. The active specific cause of cholera Asiatica is the presence and multipli- cation in the intestinal canal of the subject of numbers of very minute vege- table parasites, certain -well-defined species of bacteria known as the spirillum cholerse Asiaticse discovered by Koch in 1883, and because of their usual resemblance under the microscope to the written comma., and of the name of its discoverer, commonly called the " comma bacilli of Koch." The term "bacillus" as applied to this vegetable micro-organism is, how- ever, a misnomer, for the species is now regarded by nearly all competent authorities as a member of the group of spirilla. As commonly encountered in the intestinal contents or vomit of a victim of the disease, and in artificial culture media when growth is recent and rapid, if a fresh preparation be placed under a microscope of very high power and excellent definition, this micro-organism is usually so actively mobile as to defy distinct vision. If the fresh preparation has been made from a recent pure culture, and there be plenty of fluid under the thin cover-glass, the movements of the comma bacilli remind one of the rapid, darting, zig-zag movements of the individuals of a swarm of small flies, and of the impossibility of distinct vision of any one of the swarm. If, however, a smear-preparation from such a culture be made, and after drying and flaming in the usual manner, this be properly stained, mounted, and examined, it will be seen that each form is more or less curved — a few almost imperceptibly so ; a few others nearly as much as a semi-circle ; the greater number having a curvature representing an eighth or a quarter of a circle. The length may vary from one-seventh to one-fourth the average diameter of the red blood-corpuscle of man, the width being about a fourth its length. Examined critically it can often be seen that, instead of form- ing a segment of a circular ring, the individual form is in reality a portion of a spiral. The ends are blunt but rounded, sometimes slightly tapering, then presenting an outline similar to the fennel-seed. When proper methods of stain- ing are used each end of the " comma bacillus " is found to be furnished WMth one or more flagella, which act as motive organs. Cultivated in bouillon by the hanging-drop method, besides the above-described forms there are usually seen a variable number of more or less long and complete spirilla. Old cul- tures in bouillon, in gelatin, in agar, and in other media nearly always contain the comma and spiral forms, and intermingled with these are frequently other shapes, which many authorities regard as involution forms. Chief among the latter are spherules of a diameter from that of a cross-section of the comma to that of a red blood-corpuscle of man, and even greater. It is pretty certain that neither the comma nor the spirillum forms contain spores ; vacuoles have been mistaken for them. In the vomit and intestinal contents of the attacked the comma forms are always present for a number of days, and short and incomplete spirils may sometimes be demonstrated in smear-preparations. The comma bacillus of Koch multiplies commonly by two modes, each of which, however, constitutes essentially a process of fission : a, the comma doubles its length, and then divides into two ; 5, before dividing the comma continues its elongation into a longer or shorter spiril filament, which ulti- mately becomes segmented in order that finally the segments may separate to form new and separate commas. Of these two processes of multiplication, the former is by far the more rapid. Elongation and division of the one comma into two have been actually observed under the microscope to take place in twenty minutes. With such a rate of multiplication demonstrated, one can easily form some adequate conception of the otherwise inconceivable rapidity of PLATE IX. V^- A Fig. 1.

CHOLERA ASIATIC A. ^ 255 propagation and enormous power of dissemination in river-water of the specific infectious principle of Asiatic cliolera contained in the discharges from the bowels of a few cases, numerous examples of which the history of this disease affords ; one of the most striking being the most recent — namely, that of the river Elbe last year. Of other possible modes of multiplication, only two may be merely mentioned here : that by intervention of so-called arthrospores of Huppe, who claims that these reproductive bodies approach the tenacity of life and the power of resistance of genuine spores ; and that of so-called " oogonia " of Fer- ran — both modes being a form of multiplication by budding. The multiplication of the comma bacillus of Koch in artificial culture media has been found to vary greatly under different constitution of media and varying conditions of temperature, etc. During the development and continued growth of these organisms in artificial culture media, chemical com- binations are split up and various new chemical products formed, as the neces- sary accompaniment of the nutrition, life, or death of the microbes ; and these resultant new chemical products vary in quantity or composition, or both, wdth the varied chemical and physical complexion of the culture media, the external conditions of temperature, moisture, free oxygen, light, etc. Thus it seems to be now pretty clearly established that in artificial culture, among many other characteristics, the cholera microbe will not develop at a temperature below 57|-° F. or above 107f ° F. ; that freezing, unless it be prolonged, does not kill this microbe, but places it in a state of hibernation, as it were, ready to resume again all its vital and pathogenic functions with the return of sufficient heat ; then, on the contrary, when a temperature of 107f ° F. is exceeded the vital functions of the microbe are more and more inhibited permanently, if the tempera- ture be continued, until a point is reached, at about 140° F., Avhere the life of the microbe is destroyed absolutely in a very few minutes ; that multiplication is more rapid in fluid media of suitable constitution ; that the culture fluid, as a rule, possesses more virulence when the inoculated microbes are very recently obtained from an active case of cholera than when a long time has elapsed ; that the pres- ence of peptone in the culture medium seems to materially increase the develop- ment of the virulent power of the microbe, especially when free oxygen and light are excluded ; that there is scarcely any fluid or solid moist nutrient material of animal or vegetable composition, of a neutral or slightly alkaline reaction and not containing a substance possessing antiseptic properties, upon or in which it will not grow ; and there are at the same time many fruits and vegetables upon the pulp or surface of which the microbes of cholera will not only live for hours and days, but will multiply there even when the object gives a slightly acid reaction. This microbe will live and multiply enormously for a time in pure water, in foul water, even in sewerage, and in sea-water ; it will live for a considerable time and multiply enormously in milk, whether fresh or previously sterilized ; it is capable of living and multiplying for a time in vari- ous common beverages and on various common articles of food. It will retain its vitality, sometimes multiply exuberantly, on various textile fabrics of vegetable or animal nature for days, and in some cases weeks and even months, if they be not thoroughly desiccated or exposed to the sun's rays, and contain no antisep- tic susbtance ; if such fabrics be kept decidedly damp or wet, the germ is capa- ble of enormous multiplication, and of retaining its infectious and reproductive power to a virulent degree for indefinite periods, lasting for weeks or months, provided the sunlight does not fall upon it. If, however, these fabrics are thoroughly dry before the microbe is placed upon them, and remain or quickly become thoroughly dry afterward, it soon dies — more quickly still if exposed to the sunshine or bright reflected light. Whilst the propagative power of the 256 AMERICAN TEXT- BO OK OF DISEASES OF CHILDREN. cholera microbe outside the huni.an body, under favorable circumstances, is so enormous as to be almost incredible, fortunately for man it is, of all the dangerous pathogenic microbes known, the most susceptible to restraining or destructive influences. Whilst it is too often true that an individual, a community, a city, a whole nation, or even a continent, presenting favorable conditions for the free propagation of the infection, oftentimes suifers consequences which in their swiftness, gravity, and manifold relations may be appalling, yet there is no infectious epidemic disease which can so certainly and so easily be warded ofi" or arrested as can Asiatic cholera. Mention has already been made of the ingestion, enti-ance into the small intestine, and exuberant multiplication there of the " comma bacillus of Koch " as necessary conditions precedent to an attack of Asiatic cholera. Even with these it is probable that there must be one more condition before a serious attack follows — namely, susceptibility to the disease on the part of the individual. Since desiccation is one of the sure and rapid means of killing the microbe of cholera, and since the comma bacillus does not exist in the lungs or intestinal organs, in the blood, lymph, or muscular tissue, or in the nervous system of a person sufiering an attack of cholera, it is obvious, a priori, that the active infection of this disease is neither inhaled nor does it enter through the cuta- neous surfaces. But in this matter we are not obliged to rely upon inductive reasoning, for there is not a single example known of either mode of infec- tion in the clinical history of cholera or in laboratory experience with this dis- ease. The cholera microbe must be swallowed and pass from the stomach into the small intestine alive and endowed with vigorous powers of propagation and pathogenesis, before cholera can be naturally produced in man. There are various means and modes by which the infection of cholera may be introduced into the oesophagus of man. It may be conveyed by various fluids imbibed, such as water, milk, beer, weak tea, etc. ; by various articles of food, such as raw vegetables, bread, butter, fruits, meats, etc. ; by contact of the mouth with hands in some way soiled through careless handling of objects contaminated with numbers of the microbe, such as the clothing worn by the sick, the bed-linen used by them, the vessels containing the vomit or stools, etc. ; by water used for lavatory purposes or the washing of dishes or other food-receptacles ; by water used for washing the mouth and teeth, etc. The corollary of all this is that Asiatic cholera is not acquired by inhalation or mere contact with persons suffering from the disease, or with things contam- inated with the infectious principle. Moreover, there seems to be a natural insusceptibility on the part of many to an attack of cholera, although they be undoubtedl}^ exposed to the infection. Numerous examples of this personal immunity are furnished by every great epidemic, especially when the outbreak has been caused by contamination of the common supply of drinking-water. Furthermore, there is incontrovertible evidence to prove that there is an acquired immunity of variable duration following a natural attack of Asiatic cholera, whether the latter have been grave or mild. Indeed, it is pretty cer- tain that a natural attack so light as to have escaped recognition is capable of producing such an immunity. That an immunity can be acquired artificially by means of inoculations of various kinds and in various ways now seems to be an established fact. I need only mention in this connection the pioneer work of the Spanish physician, Dr. J. Ferran in 1884 and 1885, and after him the investigations of Petri, Brieger, Wasserman, and Kitasato, Klemperer, Klebs, and Hafkine, which with those of others constitute a body of experi- mental data so convincing as to leave but little, if indeed any, room for rea- sonable doubt. Whether or not an attack of cholera follow introduction of the CHOLERA ASIATIC A. 257 special eontagium vivum into the stomach, of man may depend upon one or more of several conditions. The acid gastric juice of the stomach is, when present in sufficient quantity relative to the number of cholera microbes, capable of quickly killing them. Hence at times when the stomach is properly func- tioning and the number of the cholera bacilli swallowed is not excessive, there is far less probability of these microbes passing the pylorus alive and still retaining their vigorous pathogenic powers than when either there is little or no acid in the stomach or but little relative to an excessive number of comma bacilli introduced. Then, again, the factor of personal susceptibility — or, if we prefer its complement, we may say the factor of personal immu- nity — may intervene (after the cholera microbes have passed into the small intestine alive, virulently pathogenic and in sufficient numbers, with certain limitations), either to render an attack of cholera more certain of development and more violent, or to pi'event it entirely, or to render it milder, respectively, as the case may be. Thus there is strong reason to believe that in Asiatic cholera as in other infectious diseases, whether the degree of susceptibility or the degree of immunity of any person be great or little, the dosage of the infectious material is a matter of importance for the generation or the violence of an attack. Any degree of immunity can be overwhelmed by an excessive dose, and any degree of susceptibility can be rendered insufficient by too small a dose. These considerations explain why it is that of so many exposed to the infection of cholera only a comparative few suffer an attack which is recognized as such. They also explain why a few foolhardy persons, whose skepticism seems to be greater than their power of discrimination, have ostentatiously swallowed voluntarily, in former times, some of the intestinal discharges of cholera victims, and in later times, some quantities of pure culture of the cholera microbe, and have lived to preach their false doctrine. When a sufficient number of vigorous pathogenic cholera microbes is intro- duced into the stomach and passes with vital properties unimpaired into the small intestine of a susceptible person, an attack of infectious cholera may be developed. In such a case the cholera microbes multiply enormously, and often with gi'eat rapidity, in the small intestine. With their growth there, under favorable conditions not yet well determined, a virulent specific chemical poison is generated. Whether this poison be essentially a ptomaine analo- gous to the highly-poisonous vegetable alkaloids, as some contend, or a species of virulent albumose, as others maintain, or a special pathogenic enzyme, as a few affirm, or possess other characteristics, or be a combination of two or more of these, it would be unprofitable to. discuss in this place. Whatever the nature of this specific chemical poison may be, it is pretty certain that when generated in sufficient quantity it attacks primarily the epithelium of the mucous membrane of the small intestine, exciting in it the phenomena of irritation and degeneration in varying degrees — according to the concen- tration of the poison and the susceptibility of the person — fi-om initial cloudy swelling all the way to complete fatty degeneration and desquamation. The irritant poison penetrates beyond the epithelium and excites in a susceptible person a round-celled infiltration of the connective tissue underlying the epi- thelium ; it may even exert its irritant powers upon the submucous layer of connective tissue, and sometimes its influence may even extend outward into the muscular and subserous coats of the intestine callino; forth in them varv- ing inflammatory phenomena. Klebs pointed out that autopsies of rapid cases of cholera showed invariably the inner surface of the small intestine to be covered with a very tenacious coating of mucus, and the experience of most observers confirms him. Another characteristic is that the serous mem- 17 258 AMEBICAN TEXT-BOOK OF DISEASES OF CHILDBEN. ])rane of the small intestine is likeAvise the seat almost ahvays of a viscid cover- ing, consisting mainly of degenerated and proliferated endothelium. The inflammatory action in the mucous and submucous coats of the small intes- tine may become so intense as to result in more or less extensive neci'osis. Very generally the mucous membrane is hypersemic. This hyperjemia may be very diffuse or it may be limited to larger or smaller areas. It is usually most marked in the region of the ileo-cfecal valve and around the Pejer's glands. The Peyer's glands and the solitary follicles are usually infiltrated and prominent, and this is so common that some French authors have regarded cholera as a specific psorenteritis. The infiltration of these glands may in some instances be so intense as to end in necrosis and ulceration. Notwithstand- ing the fact that the chemical poison of cholera attacks locally, first, the intes- tinal epithelium, and then the subjacent layers of connective tissue, sometimes even to the point of denudation and limited destruction of the latter, the cholera microbe itself never penetrates the coats of the intestine except when they are denuded, and then does not pass beyond the most superficial portion of the exposed connective tissue : it never enters the lacteals or reaches the general circulation. The chemical poison, howevei", which is produced in the intesti- nal canal by the growth of the cholera microbes therein, does not limit its action to a local attack upon the intestinal epithelium or upon the subjacent tissues ; but it is taken up by the intestinal absorbents or the capillaries of the villi, and enters the general circulation of the blood to be distributed to every organ and tissue in the body, to develop in the susceptible its secondary or constitutional action. It may be said, therefore, that cholera infectiosa epi- demica is essentially a specific systemic intoxication. It may not always hap- pen that the whole or the greater portion of the specific poison which pro- duces an attack of Asiatic cholera has been generated within the intestinal canal of the victim ; there is strong reason for the belief that exceptionally, at least, the offending material ingested already contains, before swallowing, a sufficient quantity of the specific chemical poison of cholera to produce an attack of the disease. It is probable that at least some of those attacks with a violent onset in a very few hours after exposure to the infection have resulted in such a manner, especially if the autopsy show, as it sometimes does, very little alteration of the intestinal mucous membrane. I can conceive, for example, how milk diluted with water contaminated with cholera dejecta, and then alloAved to stand for several hours in a warm place, can act as a quick and fatal poison when swallowed in large quantities. In such a case it would matter not if the bacteria were killed in the stomach by the action of the gas- tric juice; the preformed chemical poison of cholera when absorbed from the intestine and circulated in the blood might, if in sufficient (quantity, still be capable of causing a violent, and even a mortal, attack of cholera. The stools from such a victim of the cholera poison might still contain some quan- tity of that poison, but could not, in the absence from them of the living patliogenic comma bacillus of Koch, be infectious. In other words, from such a victim a new case of cholera could not arise, much less an epidemic. Furthermore, although the symptoms, course, termination, and post-mortem appearances observed in such a case would naturally be those characteristic of cholera, yet a culture test of the stools would necessarily be negative in result, and therefore misleading as to the origin of the attack, if not, indeed, of its nature. A priori, it is just among young children, who consume habitually large quantities of milk, that we should look for the largest proportion of such toxic non-contagious attacks of cholera. Symptoms. — For convenience of description in part, and in part also CHOLERA ASIATIC A. 259 because the common course of the attack furnishes the basis of the division, clinical writers have been in the habit of discussing the symptoms of Asiatic cholera under four periods : a, the prodromal period ; 5, that of serous evacu- ation ; c, that of algidity or collapse ; d, that of reaction. a. The prodromal period^ or period of incubation, varies in duration from a few hours to perhaps five days. Probably its average length may be most accurately reckoned at forty-eight hours. It is the time which elapses between the ino-estion of the infectious material and onset of pronounced symptoms. Durino- the early part of the period, sometimes during the whole of it, the subject is apparently in his accustomed health, whilst in the latter part of it, and occasionally throughout its entire length, and increasing in severity toward its transition into the next period, there may be a general feeling of distress in the abdomen, or even a tendency to nausea, with or without tenderness, restlessness, rumbling, and increased peristaltic movement of the intestines sometimes visi- ble or palpable through the abdominal walls ; laxness of the bowels or decided diarrhoea, with colored semifluid, feculent, or decidedly fluid, usually painless, sometimes copious, evacuations. All of these symptoms may be present, or only one of them, or they all may be absent. There is nothing at all dis- tinctive in their character which is in any way suggestive of their special nature. They excite suspicion only when it is known or suspected that the person may have been exposed to the infection of cholera, or when the disease is present in the locality. There is no indication of systemic intoxication dur- ing this period. The cholera microbe has merely reached the small intestine, and is more or less quietly gathering its forces for the active attack. It is engaged in multiplying itself and in generating its specific poison. The assault on the epithelial lining of the small intestine may have actually begun, and some breaches in its integrity have been accomplished ; sufiicient of the chemical poison may have been generated for the production of some hypersemia of the mucous membrane, or even for the excitement of some infil- tration of the subepithelial connective tissue ; but there has been as yet no sys- temic absorption of the specific chemical poison ; the action of the special poison is still local, although there may be experienced a degree of prostra- tion out of all proportion to the diarrhoea present. b. The period of serous evacuations may be regarded as that of sys- temic intoxication, and its duration may last from a few hours to a day or two. The prodromal diarrhoea, if it have existed, now usually assumes more gravity. The discharges become more frequent, copious, and fluid. Often, but not always, every trace of color disappears from the stools. The latter now fre- quently present the well-known rice-water aspect : they are thin, very watery, and hold in suspension more or less minute whitish flakes or shreds in great numbers ; they look like a watery gruel, in fact closely resemble the aspect of barley-water or macaroni-water. They may sometimes still be slightly colored, and they are not infrequently frothy or somewhat bloody. In fact, there is many a case of cholera Asiatica where the stools are bilious or lack entirely the familiar rice-water appearance. Often the desire to evacu- ate the bowels is sudden and absolutely uncontrollable, and the contents of the lower colon and rectum are sometimes expelled with great force without pain and in enormous quantity, saturating the bed and covering, or deluging the. clothing if the patient be still up and moving around. Nausea and vomiting are now usual accompaniments. At first the vomit may be bilious ; later it assumes the rice-water or gruel aspect. The amount of fluid discharged from the anus and mouth is often excessive. Prostration quickly becomes extreme, and thirst intense. The cry for water is constant, yet it is rejected by the 260 AJfUJilCAX TEXT-BOOK OF DISEASES OF CHILDREN. stomach almost immediately after it is swallowed. The enormous exudation of fluid into the intestinal canal reduces correspondingly the volume of the lymph in the tissues and oi-gans, and of the blood in the circulatory system. The tis- sues become abnormally dry and shrunken, and the blood markedly thickened. The number of the corpuscles of the blood is relatively much increased per cubic centimetre ; it is sometimes nearly doubled. The heart has not of itself the power to propel this thickened fluid with sufficient vigor to prevent venous stagnation. At first the pulse is very frequent for a time ; indeed, palpitation may add to the general distress and anxiety of the patient ; besides being accelerated, the pulse is usually at the same time small, feeble, and soft. Later the hearts action becomes more and more enfeebled, until the pulse is nearly or quite lost at the wrist, whilst the apex-beat may also nearly or quite disappear, and the heart-sounds themselves decidedly change their character — the systolic sound being greatly Aveakened, or even replaced by a faint blowing murmur, and the second sound lost entirely. The loss of fluid is shown in the deeply sunken orbits, glazed cornese, the pinched expression of the face, the wrinkled condition of the palmar surface of the hands and feet — the washer-woman's hands — and the general emaciation, which often becomes extremely marked. The impeded circulation of the blood is evidenced by the more or less lividity, which is most marked around the eyes, the ears, the lips, and the ends of the fingers. The surface temperature sensibly falls below the normal, sometimes markedly ; on the contrary, the rectal temperature is usually considerably above the normal. The temperature under the tongue is commonly subnormal, and the tongue itself often feels cold to the touch. Whilst the cutaneous sur- face is objectively cold, the patient himself will frequently complain of intense internal heat. The voice becomes weak, hollow, and husky. The intellect may be clear or clouded. Sometimes there is great restlessness and jactita- tion ; at other times there may be entire calm and hebetude approaching to stupor. Oftentimes cramps in the extremities and trunk may be absent or mild and fleeting, or they may be so violent as to cause agonizing pain to the patient. In the earW part of this period there is marked diminution of urine associated with albuminuria, and frequently, granular tube-casts. Very soon, however, secretion of urine is completely suppressed. While the blood is robbed of chloride of sodium and serum by the exudation into the intestinal canal, it is overladen with urea, which the kidneys fail to remove, and there is proportionately more of its salts in the central nervous system than anywhere else in the body. We have said that this period should be regarded as that of systemic intoxication. The specific chemical poison elaborated in the small intestine during the enormous multiplication of the comma bacillus of Koch, has at at length been taken up by the intestinal absorbents or has entered the net- work of intestinal capillaries, and has reached the general circulation of the blood. From this moment the scope of its action is no longer localized in the small intestine, but is now extended throughout the whole system. The presence of this specific poison in the blood of the susceptible, works changes in the complexion of this vital fluid, some of Avhich are readily vis- ible. We have already spoken of the relative increase of the corpuscular ele- ments due to loss of fluid. There is, however, a material change in the red corpuscles, probably due to the efiect of the special chemical poison : many of the red corpuscles are much paler than normal, and also much smaller ; some have been broken up into very small particles, which by reason of their form and frequent arrangement in pairs and chaplets have been mistaken for micro- cocci. The specific gravity of the blood is much increased ; there is little or CHOLERA ASIATICA. 261 no tendency of the red corpuscles to adhere together, and there is little ten- dency to the formation of large clots when allowed to stand ; if there be any separation of serum, it is very slight. The blood when drawn from the veins is very dark, almost black in color and tarry in consistence. This abnormality of the blood does not, of course, reach its height at once with the commencement of this stage, but progresses with the continuance and severity of the exudation of the fluids into the intestinal canal during this period. The blood becomes so thick and the heart's action so weak that the flow in the veins becomes exceedingly slow or seems to be arrested entirely toward the end ; it sometimes will not flow from an incision. The left side of the heart may contain but little blood, and the large arteries, which are often spasmodically contracted, are nearly empty. The right side of the heart, on the contrary, is full oftentimes to over-distention. The lungs are usually found, post-mortem, to be quite pale, bloodless, and retracted well against the spinal column. In the mesenteries the arteries are much contracted, while the veins are greatly dilated, and there is usually also capillary engorgement. In fact, this condition of strong contraction and emptiness of the calibre of arteries, Avide dilatation and fulness of the veins and capillaries, is observable nearly everywhere. There are often also small ecchymoses, aud sometimes rather extensive extravasations, particularly at the mucous surfaces. (Edemas, how- ever, are not to be met with ; notwithstanding the numerous stagnations of the blood-current in veins and capillaries, the flow of fluids of the blood into the intestinal canal is so great, and the consistency of the blood has become so thick, that everywhere else than at the mucous surface of the intestines the tendency to fluid exudation has been completely arrested. The ecchymoses above mentioned are more abundantly scattered oven the mucous and serous surfaces than elsewhere, although they may exist even in the muscular tissue. The toxic influence of the specific chemical poison in the blood is probably most marked upon the central nervous system (including the sympathetic gang- lionic system), and upon the liver and kidneys, especially the latter. The mechanical results of loss of such an enormous qauntity of body fluid may in some part account for the seriousness and severity of the symptoms of this and the following period ; but doubtless the action of the chemical poison in the blood upon the nervous system, the liver, and the kidneys is even superior. The first onslaught of the poison upon any important internal organ after reaching the blood naturally falls upon the liver. This organ is generally smaller than normal, flaccid, and anaemic, and contains less glycogen than normal. The outlines of the lobules are more or less indistinct ; the interlobular network of blood-vessels may or may not be dilated and filled with blood ; the radiating cellular trabeculge of many lobules are decidedly narrowed, while the inter-tra- becular blood-capillaries of some portions of acini are dilated and filled with blood-corpuscles. The hepatic cells of many acini are granular and difficult to stain. Some investigators contend that there is actually some atrophy of the liver. The gall-bladder, the cystic and common ducts, are distended with a thin brownish or greenish fluid, whilst the interlobular biliary network is not appreciably altered. Whilst the biliary ducts and gall-bladder are full, the intestinal end of the ductus communis choledochus is usually practically imper- meable, and the intestines rarely contain any bile. The spleen is contracted and often flabby. Next to the intestinal lesions in cholera the kidneys show the greatest pathological changes. The eff'ect of the cholera poison in the blood falls heavily upon these emunctories. Grranular degeneration of the se- cretory tubules of the cortex soon becomes marked, but is irregularly distri- buted at first. After this pathological process has continued for some time^ 262 AMEBIC AX TEXT-BOOK OF DISEASES OF CHILDREX. fatty degeneration of the tubular epithelium becomes general and intense, and associated sometimes -with parenchymatous inflammation. The suppression of urine is therefore not alone due to the mechanical eifects of thickening of the blood. c. The period of algidity or collapse may follow after a few hours of con- tinuance of the period of serous evacuations, and may last for some or many hours until death or reaction ensues. In this desperate condition prostration is extreme ; the voice is gone ; respiration is very feeble, shallow, and fitful ; the pulse has vanished and the heart almost ceases to beat ; so also the nausea, vomiting, and cramps, the frequent enormous forcible evacuations of the bowels, whilst, instead of the latter, the contents of the intestines dribble away from the anus, whose sphincter is inactive. Profound stupor or coma is the rule. The general lividity is intense : the coldness of the skin is like that of marble. The vital forces are nearly overwhelmed by the great losses of fluid sustained, by the effete substances which are accumulated, and by the special cholera poison. During this period the vital spark flickers very faintlv ; life hangs trembling in the balance. The pathological conditions are essentially those of the previous period, intensified. d. Tlie period of reaction may be short or prolonged, and directly follow either of the three preceding. It may last from three or four days to as many weeks. AY hen it follows immediately upon the prodromal period, convalescence is usually rapid and short, and the wonted health is soon perfectly re-established. In such a case there is, after all is over, of course, great doubt that the attack was choleraic at all. The finding of the comma bacilli of Koch in the stools is the only certain criterion of what its true nature has been. When the period of reaction immediately follows the period of serous evacuations, it is usually the more definite the more serious the symptoms and pathological lesions during the latter period have been. If there have been great altera- tions of the mucous membrane of the intestines, profound general intoxica- tion, with great destruction of the red elements of the blood and marked de- generations in the liver and kidneys, we may expect to witness a more or less prolonged, complex, and dangerous period of reaction. In fact, as a rule, more patients die during than before reaction, when the latter follows immedi- ately the period of serous evacuations. The gravity of the symptoms and general condition of the patient may slowly ameliorate or quickly improve, or one set of alarming symptoms may simply be substituted by another set, Avhich, although not so frightful to the laity, will be regarded by the experienced phy- sician as onlv a prolongation of the critical struggle between the very evenly balanced forces of life and of death. The evacuations from the stomach and bowels decidedly lessen in frequency and copiousness ; the stools lose their barley-water aspect ; the bile reappears in them, and they assume gradually the common characteristics of an ordinary diarrhoea, sometimes stained with blood ; or if the local destructive effects of the cholera poison have been drastic, there may be grafted upon the diarrhoea a more or less pronounced dysenteric condition with bloody stools and tenesmus. The characteristic aro- matic sperm-like odor of the rice-water stools may now change to the foul, stinking odor of decomposition, and the flatulence which was absent during the preceeding period may become annoying. The voice becomes stronger, respiration more steady and fuller. The heart gradually regains its lost powers: tha pulse begins again to be felt at the wrist ; the surface tempera- ture again goes toward the normal and quickly passes above it ; the shrunken countenance begins to discard the Hippocratic expression, the sunken orbits to fill up and the glazed eyes to brighten ; prostration becomes less marked, CHOLERA ASIATIC A. 263 thirst less intense ; the secretion of urine is slowly re-established, at first con- taining much albumin, granular casts, and large quantities of urea ; appetite and digestion are slowly recovered as a rule. In fortunate cases the restora- tion to health and to the proper exercise of all the bodily functions may be rapid and complete. But in other cases anaemia, due to the great injury to the elements of the blood, may be protracted ; or the functions of the much-damaged kidneys may be slow of re-establishment ; or the destruction of intestinal epithelium may leave denuded patches in the subepithelial layers of connective tissue, and thus occasion prolonged irritation and even serious derangement of the processes of digestion, and at the same time furnish numerous points of entrance for various septic micro-organisms. In truth, a secondary septic fever, as the result of systemic invasion in this manner, is not at all uncommon in this period : it is vulgarly called the typhoid stage of cholera. When the patient passes through the period of serous evacuations and that of algidity or collapse, the period of reaction usually differs only in degree from the conditron above described. It can be now readily understood why almost as many victims succumb during the period of reaction as during the periods of specific action of the cholera poison. Even after convalescence has been established impaired health may persist for a long time, evinced by chronic anemia, stubborn disorders of the digestive apparatus, and easily dis- turbed bowels. Before convalescence is fully confirmed, and even for some time afterward, imprudences of diet sometimes precipitate a dangerous relapse. Special Phases of Cholera. — In a virulent epidemic of cholera the cases of very sudden and violent attacks, which do not seem to have been preceded either by a prodromal period or the one described in section h, are sometimes numerous, and they are most frequently encountered near the commencement of the outbreak. These attacks have been variously named foudroyant, toxic, asphyxic. In description of these foudroyant attacks we cannot do better than quote the recent language of Dr. N. J. Simpson, the health ofiicer of Cal- cutta : " On these occasions the suddenness of the attack, the number affected, and the virulence of the disease would incline one to think that the specific organisms had already elaborated outside the human body a strong poison which acted on the victim almost immediately after being swallowed. Under the most favorable conditions for the elaboration of such a poison there will not, as far as can be ascertained, be the usual twelve to forty-eight hours' period of incubation ; on the contrary, patients will be brought into hospital in a dying state, though taken ill only a short time previously ; some will die before reaching the hospital ; and the ratio of mortality is likely to be 75 to 85 per cent. The description given by Dr. Jamieson in 1817 seemed to me until some time ago somewhat exaggerated, when the cases seen during an outbreak at a large pilgrimage convinced me of the correctness of Jamie- son's accounts as applied to exceptional outbreaks. He says : ' Sometimes there was no vomiting, sometimes no purging, sometimes no spasm throughout, sometimes all these symptoms were simultaneous, and the vomiting and purg- ing took place together, as if caused by sudden contraction of the alimentary canal in its whole extent. In some rare cases the virulence of the disease was so powerful as to prove immediately destructive to life, as if the circula- tion were at once arrested and the vital powers wholly overwhelmed. In these cases the patient fell down as if struck by lightning, and instantly expired. Others, again, sank after making one or two feeble eiforts to vom'it and draw- ing a long and anxious inspiration ; some recovered from the insensibility pro- duced from the first shock, and afterward went through the regular course of 264 A3fEBICAN TEXT-BOOK OF DISEASES OF CHILDREN. the disease.' In these and similar cases a virulent poison is the best expla- nation of the symptoms and apparent absence of the period of incubation, and of the destructive nature of the disease." Another phase of cholera still more rarely met with is what has been termed cholera sicca. In this there is no vomiting, no purging, but the other symptoms may be little different from those already described. The autopsy shows, however, that there has never- theless been great exudation of fluid into the intestinal canal, for the latter is greatly distended with it from end to end. S])ecial Complications of Clwlera. — I have already spoken of frequent occurrences of ecchymoses, especially on the mucous and serous surfaces. Cutaneous petechiiie and eruptions are not uncommon in the period of reaction ; they appear less frequently during that of serous evacuations or algidity. These eruptions, more often observed on the face, neck, and forearms than elsewhere, are usually more or less punctate, the puncta being slightly elevated and having a tendency at times to aggregate into irregular groups. These spots vary somewhat in color, but most frequently the points are dark or black. In some rare cases the vitality of the skin seems to be in a degree impaired, as indicated by a disposition to ulcerate upon small provocation ; for example, bed-sores may sometimes develop early and become an exceedingly trouble- some complication. The cause of these eruptions is unknown, but if we were to express a mere conjecture, it would be that they may be due to innumer- able minute thrombi and emboli — small clots which have formed during stasis of the blood. Diagnosis. — The differential diagnosis of Asiatic cholera by means of its symptoms alone is, during the absence of an epidemic of the disease, one of the most difficult feats the clinician is ever called upon to perform. Indeed, it is held by some of the most skilful and renowned clinical diagnosticians in the world to be an utter impossibility to make a certain diagnosis ; and it is, and always has been, the common experience of the whole world that the saddest, and for the public health the most deplorable, mistakes are very often made even by the most experienced. And yet there is no single one of the whole category of diseases with respect to which a mistake in diagnosis of a first case may, and sometimes does, entail such an endless series of incalcula- ble public calamities. There is not one of the symptoms, and of the groups of symptoms, met with in some period of an attack of Asiatic cholera, which does not perfectly resemble those of some disease which is more or less common. Among these commoner affections for which Asiatic cholera may be mistaken clinically are cholera morbus, arsenical poisoning, pernicious inter- mittent fever, and poisoning from consumption of various articles of food in special states of decomposition or fermentation. Of course during the prevalence of an epidemic in a locality, the physician of that place will Avisely regard and treat every case presenting the symptoms common in Asiatic cholera as an undoubted case, and will not hesitate to handle it as such ; for the community will unquestionably uphold him. It is, however, just when the physician is most uncertain — namely, in dealing with those doubtful cases which precede and follow the epidemic — that the real interests of the community and of the general public demand the greatest cer- tainty of diagnosis ; but then, as a rule, the people are unwilling to submit to restraints. Fortunately, through the discovery of Koch in 1883 and 1884, we now possess the means of making an absolutely certain differential diagnosis of cliolera infectiosa epidemica, and without reliance upon clinical symptoms, which may be misleading, or upon trustwoi'thy knowledge of the previous history or relations of the patient, which may be difficult or impossible to obtain. The CHOLERA ASIATIC A. 265 presence or absence in the stools of the suspect of the comma bacillus of Koch promptly and definitely settles the matter. This can be determined within forty- eight hours by resort to the microscopic and biological tests. These tests, however, should never be relied upon when made by a tyro. They are too difficult of application to be trusted to the inexperienced. To describe here the methods of procedure would therefore be useless, for the experienced bac- terioloo^ist does not need such instruction, whilst the unskilled would need much more to be rendered capable. During times of great danger of the introduction of Asiatic cholera into a locality all cases presenting the symp- toms of cholera should be handled as suspicious until a differential diagnosis by means of the microscopic and biological tests be made by a thoroughly competent and experienced bacteriologist. Prognosis. — The outcome of an attack of cholera depends very much upon what period of the seizure medical advice is had, very much upon the slowness or rapidity with which grave symptoms appear and persist, very much sometimes upon the period of the epidemic at which the attack happens, and very much upon the constancy of intelligent care in handling the case from first to last. Wise and prompt treatment of the first stage usually aborts the attack almost in the beginning, and is folloAved by scarcely any mortality. In the vast majority of such cases the attack never gets beyond the stage of premonitory diarrhoea, and convalescence is usually rapid and complete. The prognosis of a seizure which has passed into the second period, or that of pro- nounced serous diarrhoea, is grave ; the mortality varies greatly, from 25 to 60 per cent, of attacks, by reason of the varying susceptibility of patients, vary- ing doses of the specific poison, varying promptness, persistency, and wisdom of treatment. The prognosis of an attack of Asiatic cholera in the period of algidity or collapse is truly desperate, and the mortality has usually been frightful, not infrequently having reached 80, 90, and sometimes 100 per cent. The prognosis of an attack which has reached the period of reaction varies greatly according to the damage which may have been done the intestinal lin- ing, the secretory elements of the kidneys, the glandular elements of the liver, and the elements of the blood, and in proportion to the accumulations of effete material and of specific poison in the blood and tissues. It is sufficiently serious to require careful nursing and wise medical direction ; where septic poisoning has been engrafted upon the cholera attack, it is often grave. Speaking generally, the mortality of epidemics of Asiatic cholera is usually greatest in the early course of the outbreak in the locality, and is limited almost entirely to those who neglect to invoke the aid of the physician until the attack has become exceedingly grave. The general mortality among the attacked may vary between 20 and 80 per cent., according to the virulence or mildness of the type of the disease, the total average being nearly 50 per cent. If the patient is seen early and is promptly, judiciously, and constantly cared for, the danger of a fatal issue is usually not great. Treatment. — Although the gross number of attacks of Asiatic cholera and the wide spread of pandemics of the disease among civilized nations have lessened considerably, thanks to better hygiene and improved methods of pre- vention, yet the percentage of deaths to attacks remains about the same now as it was many decades ago, and is not very materially lower under mod- ern and civilized systems of therapeutics than it has been under antiquated and semi-civilized or barbarous modes of management. Knowledge of efficient methods of treatment of cholera has by no means kept pace with that of the etiology and prophylaxis of the disease. In the early stages of this disease the skilful physician is all powerful ; in the latter stages he is almost 266 AMERICAX TEXT-BOOK OF DISEASES OF CHILDREN. impotent. Hence tlie paramount advantage of prompt and judicious medical treatment. Treatment in the Premonitory Period. — During the prevalence of Asiatic cholera in a locality, every disturbance or derangement of the ali- mentary canal should be corrected without loss of time. Indigestion or abdominal distress should receive without any delay the careful attention of the physician, who should not fail to impress upon his clientele the urgent necessity of scrupulous obedience to his instructions. The first thing to do is to remove any apparent cause of the disturbance ; place the patient upon a lighter diet, fluids by preference ; absolutely interdict any exercise which tends to overheat or fatigue ; insist upon clothing during the day which will keep the trunk and extremities warm, and, during the night, which will prevent chilling of the abdomen and the legs. One article of clothing should consist of a broad flannel binder around the abdomen and loins next the skin, kept on day and night. The first appearance of diarrhoea should be the signal for active treat- ment. One or two stools during the twenty-four hours more than the usual num- ber habitual to the individual when in health, or a single copious watery stool, should require the patient to be put to bed at once and kept recumbent, not only during; the continuation of looseness of the bowels, but for a dav or two after this condition has entirely disappeared. All solid food should be rigidly interdicted, and nothing but broth, bouillon, or whey, alloAved to be eaten. In fact, an approach to abstinence is far more desirable than risk of overfeeding. The looseness of bowels or diarrhoea must be arrested as soon as possible, but in doing this it is much better to avoid powerful astringents and strong opiates if it can be done without them. In the choice of the remedy it should be borne in mind that the nature of the disturbance is that of a specific infection of the small intestine by the comma bacilli of Koch, associated with, and greatly favored by, a rather decided alkalinity of the intestinal fluids. The rational treatment would therefore seem to be the administration of some combination of acids, disinfectants, and sedatives. Of the acids which may be employed in proper doses are sulphuric, hydrochloric, lactic ; of the intestinal disin- fectants, naphthaline, salol, calomel, salicylate of bismuth ; of the sedatives, paregoric, Hoff"man"s anodyne. Aromatic sulphuric acid and paregoric in proper doses may be given and repeated j!?. r. n. This may be alternated or not with naphthaline or salol, alone or in the same powder with salicylate of bismuth, or with naphthaline and calomel together. It will be found in the great majority of cases that this simple treatment will prove effective. Instead of the mineral acids, lactic acid is preferred by many. Dujardin- Beaumetz uses — I^.

For the adult three teaspoonfuls, with or without 20 drops of pare- goric added, at intervals of a half hour, or longer as the case may require. As a drink instead of water, it is Avell to use an acid lemonade with a view to lessening the alkalinit}" or rendering acid, if possible, the reaction of the contents of the small intestine, in order to inhibit the growth therein of the specific microbe. Sulphuric, hydrochloi'ic, or lactic acid — say, one part to the thousand of sterilized water, sweetened — may be employed for this pur- pose. CHOLERA ASIATICA. 267 Should the diarrhoea persist or increase in severity in spite of the simple treatment above mentioned, recourse must be had without loss of time to more active medication. Stronger anodynes and decided astringents are called for. Chlorodyne may be used, or Lausedat's drops, as follows : ^. Tr. Valerianae aether TTLc. Tr. opii Kllxx. Essentiae menthse piperit gtt. v. Spts. setheris comp TTLc. — M. Sig. Five to eight drops for a child of six years. Or something like the following may be tried : I^. Acid, tannici Plumbi acetat aa gr. iij. Pulv. opii gr. ss. Oleoresinse capsici gr. ij. — M. Ft. pil. No. XII. Sig. One pill every one to four hours, p. r. n., at the age of six years. On the principle of clearing the bowels of irritants and altering the secre- tions, some begin the treatment of this period with a large dose of calomel, followed in a few hours by castor oil combined with naphthaline. Treatment of tpie Period of Serous Diarrhcea or Systemic In- toxication. — Although such early treatment as indicated above will, as a rule, prove effective in the prevention of full development of an attack, there are some cases Avhich seem to be doomed, in spite of prompt and judicious attention, to advance into the period now under consideration. Moreover, it it is usually not until this period that the physician is called. The conditions now to be contended with are those which have already been pointed out. For the vomiting and thirst cracked ice and sinapisms to the epigastrium ; for the coldness, envelop the whole person in hot flannel blankets, with bottles of hot water next the skin, and immersion in a hot bath for fifteen or twenty minutes at intervals of two to four hours ; for the cramps, friction by rubbing with the palms of the hands : if the pain be violent it may be allayed by inha- lations of ether ; for the prostration and restlessness, cardiac stimulants and nervous sedatives ; for the purging, chiefly intestinal antiseptics and correc- tives ; for the loss of fluid, hypodermatic or intravascular injections of saline fluids ; as against the special poison in the intestinal canal, irrigation of the colon with large injections of saline fluids. Among the legion of remedies which have been tried and often been found wanting, the favorite East Indian compound called chlorodyne has been about as useful as any. Lausedat's drops, already mentioned, may take the place of chlorodyne. The remedies mentioned in treating of the prodromal period, es- pecially the acids and antiseptics, may still be useful in the early part of the stage now under consideration. A powder which has been often used in former epidemics to combat coldness, prostration, and collapse has the following com- position : I^. Bismuthi subnitrat 5j. Plumbi acetat gr. iij. Camphorse g^'- ij- Oleoresinge capsici gr. j.^M. Divide in chart. No. XII. Sig. One every hour or two. 268 A3IEBICAN TEXT-BOOK OF DISEASES OF CHILDREN. Macnamara, the great Anglo-East-Indian authority on cholera, says : " I think Avater, though urgently demanded by the patient, should be refused (cracked ice is recommended instead). I would restrict the opium to three grains ; it is unwise to give more, although Ave are welluigh certain that much of it has been vomited If the vomiting is very severe, a single dose of twenty grains (for the adult) of calomel will sometimes relieve this symptom. A mixture may be added, each dose of which contains two grains of acetate of lead and fifteen drops of dilute acetic acid, to be taken every second hour, and fifteen drops of dilute sulphuric acid in water every alternate hour, so that the patient should take a draught of first one mixture and then the other every hour. In this way the alkaline stools become acid, and pei'haps destroy the cholera organism in the intestinal canal. However this may be, these acids seem to be beneficial in the treatment of cholera I believe that alcohol is positively harmful in any stage of cholera." Unfortunately, in this stage of cholera medication by way of the stomach is always impeded, very often rendered almost useless, sometimes quite impos- sible of eifecting an impression, by reason of the vomiting and the failure of absorption in the intestines. If the little that is not rejected by the stomach succeeds in reaching the intestine, it so often happens that none of it is absorbed ; powerful drugs may lie and accumulate in the latter, to cause actual harm when the stage of reaction is ushered in, and with it restoration of the function of intestinal absorption. Neither can ordinary rectal injections of medicine be depended upon, for the same reason. The sluggishness, sometimes practical stagnation, of the little lymph still remaining in the tissues, after the continuous drain of copious watery evacuations from the bowels, usually lessens, often quite nullifies, the customary results of hypodermatic medication. When such a condition arises, as it unhappily too often does, what other resources has the physician left to him ? There are still three which, used judiciously and skilfully, are powerful to restore marvellously — at least for a time, sometimes permanently — the suspended functions. I refer to intestinal, to hypodermatic, and to intravascular irrigation. Unteroeh/sis, first introduced by the late Prof. Cantani of Naples during the former cholera epidemic in Italy as a means of treating all stages of the disease, consists essentially in irrigating the rectum, colon, and, if possible, also the small intestine, Avith large quantities of a Avarm, astringent, antiseptic, sedative fluid. The following is Cantani's formula for an adult : I^ Boiled Avater or infusion of chamomile . . 2 quarts. Tannin 11 to 21 drachms. Laudanum 30 to 50 drops. Powdered gum-arabic 1^ ounces. The temperature of this mixture when introduced should be sufficiently above the normal to aid in restoring heat to the body. Of course the quantity injected should vary according to the age of the patient and other circum- stances in the judgment of the physician. The best time for administration is immediately after an evacuation. Hiipodermodysis, also first introduced by Prof. Cantani as a means of treating especially the stages of serous diarrhoea and of algidity or collapse, consists essentially in the introduction hypodermatically of a large quantity of warm saline fluid for the purpose, primarily, of replacing the fluid lost through the intestinal drain ; secondarily, of Avashing out from the blood and tissues much of the efl'ete material and specific poison Avhich have accumu- . CHOLERA ASIATIC A. 269 lated in them. Cantani's formula for an adult consists of 2 quarts of boiled water, 2|^ ounces of pure sodium chloride and a drachm and a half of sodium carbonate. The quantity to be injected each time varies according to age, the apparent amount of fluid lost, and other circumstances. The amount for an adult is one to two and a half quarts. The temperature of the solution when injected should be 100|^° F., unless that of the rectum be very low, in which case it has been sometimes raised as high as 109f ° F. The most successful time for resort to hypodermoclysis is at the first indications of insufiiciency of water in the body, such as Hippocratic countenance, wrinkling or discoloration of the skin, cramps, coldness, etc. Intravascular injections of saline fluids, a procedure as old as the history of cholera in Europe, has had a renewed trial during the present visitation of the disease. Injection into veins and into arteries has been practised especially at Hamburg, and each method of procedure has its champions. Some variations in the constitution and proportions of the saline fluid used occur, but the following may be regarded as a standard : sodium bicai'bonate 1 part, sodium chloride 6 parts, boiled water 1000 parts. The temperature of the fluid when injected varies according to circumstances from 100|-° F. to 104° F., more frequently the latter. The quantity administered has sometimes been very considerable, averaging for the adult one to two quarts. The injec- tion may be repeated in a half hour to four hours, as the condition of the patient demands. Of the relative advantages and disadvantages of the hypodermatic and intravascular irrigations, it may be said that the former is slower and usually more permanent in its action than is the latter. There may occur occasions, however, in the treatment of the algid period, when the matter of time will decide which method shall be tried first. It seems to me that it is mainly in rapidly-sinking cases in that period, that intravenous injection should be given the preference, to be followed at the second injection by hypodermoclysis. The hypodermoclysis has the further advantage of being far simpler of application. Only one skilful person is required for this operation ; indeed, the attendants can readily be instructed to perform it very safely in the absence of the physi- cian. On the contrary, the physician requires at least one skilled assistant to safely perform the intravascular injection. In all these operations strict antiseptic or aseptic precautions must be observed. For enteroclysis there is needed a large fountain syringe with a long flex- ible tube with a cock, to which a moderately stiff but flexible terminal portion two or three feet long is attached. The tube, quite full of the fluid, must be passed up into the colon and worked along its interior as far as possible ; the fluid should be let flow slowly, avoiding very sudden distention of the gut, and should be retained as long as possible. For hypodermoclysis a fountain syringe with a long flexible tube, furnished with a cock, answers the purpose ; with another shorter tube, one end attached to the cock, the other having a needle-pointed canula, a little longer, stronger, and with a somewhat wider calibre than the ordinary hypodermic needle. The tube and canula are first perfectly filled with the fluid, and then the canula is inserted well in between the skin and deep fascia of the flanks, buttocks, or interscapular region. The fluid should be made to flow slowly, allow- ing fifteen to twenty minutes for the introduction of one quart. The slight tumor should be made to disappear, as it will, by gentle kneading or massage. For intravascular injections of saline fluids any good transfusion apparatus suffices. 270 A3IEBICAN TEXT-BOOK OF DISEASES OF CHILDREN. Lavage of the stomach to stop vomiting is a most effective procedure, and sometimes succeeds in arresting this distressing symptom when nothing else will do it. Indeed, it Avould seem to be a very useful associate of enteroclysis, for it seems that to clear the stomach of the offending rice-water fluid is only second in importance to washing it out from the intestine. Boiled Avater hold- ing in solution boracic acid has been satisfactorily used for this purpose. Treatment in the Period op Algidity or Collapse. — In this stao-e of the disease, where absorption is practically suspended, little is useful beyond enteroclysis and hypodermoclysis or intravascular injections of fluids, and efforts to communicate heat. The vast majority of cases in this stage die in spite of every effort of the physician, but there is certainly more success to be expected of this mode of treatment than of any other at present known. Treatment in the Period of Reaction. — The treatment in this stage is essentially expectant and symptomatic. Each condition enumerated in the sections on Symptomatology and Etiology will suggest to the experienced the particular line to be followed. One of the most important things to avoid is pointed out forcibly by Macnamara, whom I can do no better than to quote in conclusion : " When reaction comes on, we must be careful not to fall into the error of over-feeding the patient under the mistaken idea of supporting his strength ; he will not die of exhaustion if small quantities of milk and arrow root are administered frequently for two or three days, together with warm beef-tea enemas. But enteritis may certainly be induced if food beyond the simplest and smallest quantities be alloAved. The patient requires rest and the most careful nursing after a severe illness like cholera." Prevention. — Whilst the physician is often impotent in the treatment of cholera, in prevention he may be, if he will, all-powerful. It is not our pur- pose to discuss this subject from the standpoint of a state or community; we shall consider the matter solely from the side of the individual : First, what those ministering to the sick should do to prevent the spread of the disease ; second, what the individual who may be exposed to the infection should do to safeguard himself from an attack of cholera. 1. The Duties of those Attendant upon the Sick. — I wish to say in the beginning that, whilst there is scarcely any infectious epidemic disease which is so capable as cholera of working great injury in various ways to the com- munity, if the attendants upon the sick are ignorant or careless in applying the principles of prevention, yet there is no such disease which can so easily and certainly be limited to those attacked if only these principles be constantly and scrupulously applied. As I have said elsewhere, Asiatic cholera can be dwelt with and handled with absolute impunity if only the proper precautions be never once forgotten or neglected. Thei'e is, therefore, not the slightest danger in administering to the sick if carefulness be the rigid rule. It has already been pointed out that it is only the evacuations from the stomach and bowels of a person suffering an attack of Asiatic cholera that contain the original infection. To promptly and thoroughly disinfect these and everything soiled by them or contain- ing them is to render the spread of the disease from the person attacked impossible. The evacuations should without any delay be treated in one of the following ways : a, water that is boiling should be poured upon them carefully, so as not to splash, in such amount that the volume of the water is four times that of the evacuations, or a strong solution of potash soap may be used in the same way ; 5, or fresh milk of lime (white wash), of twice the volume of the evacuation, should be poured upon the latter and the mixture gently stirred ; c, or a similar quantity of a freshly-prepared solution (5 per cent, strong) CHOLERA A STATIC A. 271 of chloride of lime may be used in the same way ; d, or a similar volume of 5 per cent, solution of carbolic acid may be thus employed. Which- ever one of these means be chosen, it is essential that the vessel be im- mediately covei'ed from the flies and allowed to stand fifteen or twenty minutes before emptying ; and it is also essential that the disinfected evacuations be emptied into a pit in the earth, the bottom of which is covered with a layer of quicklime, and be covered immediately with another layer of the same mate- rial, care being taken that the location of this pit does not jeopardize water- courses, springs, or wells. Clothing or other textile fabrics soiled by the evacuations should be disinfected as soon as possible. They should be at first soaked in a disinfectant solution — say, a mixture of strong potash soap and carbolic acid of 5 per cent, strength — for an hour or more, and then boiled. It is better to burn bedding rather than attempt its disinfection. The floors of the sick-room should first be sprinkled with chloride of lime, and then mopped over with a cloth moistened in a chloride-of-lime solution. Any article of furniture which may have been contaminated should be carefully disinfected. Finally, it would be well to disinfect the room itself, after all is over, by means of sulphur fumes, 3 pounds to the 1000 cubic feet of space, for eight to ten hours. No one should be allowed in the sick-room except the necessary attendants, who under no consideration should eat or drink in this room. The patient should be fed from a set of dishes which should be disin- fected immediately after use, and kept separate from those of the rest of the household ; the remains of the patient's meal should be disinfected and destroyed. After handling the patient or anything that he has soiled, the attendants should immediately first disinfect and then carefully wash their hands : this thorough ablution should be performed invariably immediately before eating. After vomiting or an evacuation of the bowels the mouth and the parts around the anus should be wiped with a cloth Avet with solution, 1 : 2000, of corrosive sublimate. If convalescence supervene, the patient should be kept isolated for a week, and the stools should be disinfected during that time. If death occur, the corpse should at once be enveloped in a sheet soaked with corrosive sublimate, 1 : 500, and cremated or buried without delay or funeral cortege. Finally, promptly notify health officials of every suspect or known case of cholera. 2. Individual Precautions for the Exposed. — No water or milk should be used or consumed, which could by any possibility be contaminated, unless recently boiled. No cold or uncooked food should be eaten which could possibly become contaminated. Such things as salads should be avoided. Unripe or over-ripe fruit should be eschewed. Alcoholic stimulants are per- nicious. In fact, excesses of all kinds predispose to an attack. Regularity in eating, sleeping, exercise, and all other habits, contributes to safety. Keep all the bodily functions well regulated ; avoid fatigue and chills. The use of a broad flannel waist-bandage next the skin day and night is beneficial in guarding against abdominal congestions. Quickly correct the slightest intesti- nal disorder. DIPHTHERIA. By DILLON BROWN, M. D., New York. Diphtheria is an acute, contagious, and infectious disease, the most characteristic and constant feature of which is a pseudo-membranous exu- date on, or a superficial necrosis of, a mucous membrane or some part of the skin which has been denuded of its epithelium. Although a comparatively recent disease in this country, it threatens to be the scourge of the large cities. Less than a century ago but few isolated and poorly-understood cases were seen, but the disease has spread very rapidly during the past fifty years, and in New York City alone the mortality from diphtheria and croup has exceeded fifty thousand in twenty-five years. And this number does not include many cases which were reported as deaths from pneumonia, nephritis, heart failure, etc., which were really complications of diphtheria. There is no guide to the virulence of diphtheria. It is one of the most dreaded, one of the most fatal, and one of the most common diseases of child- hood. At the onset it is impossible to say whether the disease will be mild or malignant. A case beginning with high fever and profound constitutional disturbance may go on to a rapid recovery ; while, on the other hand, an apparently mild case will grow depressed and weak, and slowly die. Neither does the amount nor character of the exudate give any certain prognosis. Indeed, the clinical symptoms vary to such an extent that many mild cases are not even recognized unless some post-diphtheritic complication ensues ; but, although these mild cases may be of small danger to the individual, they are all diphtheria and all e(|ually contagious, and may be the origin of the most malignant ones. Etiology. — It has been well recognized that certain cases of croupous inflammation are not true diphtheria. This list includes the chronic membra- nous exudates seen in certain forms of fibrinous bronchitis, cystitis, enteritis, etc., the acute superficial necrosis of the mucous membranes due to direct heat, as a scald, or an intense irritation from the application of ammonia. However, excluding these, there remain many doul)tful cases ; but modern bacteriological research seems to have solved this problem, and proven beyond much doubt that there are at least two forms of pseudo-membranous inflam- mation, the one a true diphtheria, due to the Klebs-Loeffler bacillus, and the other, which may include several varieties, a pseudo-diphtheria, due usually to a streptococcus. True diphtheria is the product of the Klebs-Loeffler bacillus, either alone or associated with other bacteria, and it is pi'imarily a local disease with many secondary manifestations, due to the absorption of the ptomaines or poisons which result from the growth of this micro-organism. The following obser- vations seem to establish these propositions as fairly well proven : 1. This bacillus is present, usually in large numbers, in the false membrane 272 DIPHTHERIA. 273 of all typical cases of infectious diphtheria, and is rarely or never found in other inflammations of the mucous membrane of the throat or in the healthy- throat. 2. This bacillus is al^'ays found at the place of local infection, and never found in the blood or any of the internal organs, even though they may be the seat of marked secondary changes. On the contrary, streptococci and other bacteria may be found in the blood and internal organs. 3. Pure cultures of this bacillus ^vhen injected into the mucous membrane of susceptible animals produce a typical diphtheritic inflammation, even to paralyses and organic lesions. 4. Inoculation of animals with the toxalbumin of this bacillus produces the sepsis, the paralysis, the visceral lesions, and all the secondary constitu- tional symptoms of diphtheria, "without the membrane. 5. Clinically, surface diphtheria, -without participation on the part of the Ivmph- vessels, is apt to exhibit little or no fever ; the disease does not run a typical course ; one attack does not offer security against its recurrence in the future ; and whenever the diphtheritic infecting agent finds a foothold on the body — as, for example, by inoculation — it always excites a local affection at the point of entrance ; and from this local infection the general infection -will develop, the extent and rapidity of which depend upon the anatomical rela- tions of the affected parts, their characteristics, and their power of absorption. The hypothesis that diphtheria is at first a general disease of the blood, with secondary manifestations on the mucous membranes, is hardly tenable in face of the foregoing facts. The chief arguments brought forward in support of this theory are its similarity to certain of the infectious diseases ; its epi- demic occurrence ; the fact that constitutional symptoms may be present for hours and days before local symptoms are discovered; the marked susceptibility of children ; the great disproportion often seen betAveen the general symptoms and the apparently trifling local changes; the multiplicity of the localizations, and the fact that eff"orts to conquer the disease by destroying the pseudo-mem- brane with strong caustics have been for the most part without result. However, these observations simply prove that diphtheria may be a general infectious disease, but they do not explain how this infection takes place. Neither clin- ical observations nor post-mortem examinations have ever been able to present enough facts to settle this question ; but. fortunately, modern bacteriological research, with inoculation experiments on living animals, has determined it very conclusively. Besides trae diphtheria, we frequently meet with an allied pseudo-mem- branous inflammation which cannot be distinguished from it clinically, except that it runs a milder course. Bacteriologically, however, the Klebs-Loefiler bacillus is always absent, and streptococci, and often other bacteria, are found in great abundance, not only in the exudate, but even in the blood and internal organs. The differential diagnosis is very important, as a knowledge of which disease we have to deal with modifies somewhat the treatment, and greatly the prognosis. Not only do we have a croupous inflammation which is not a true diph- theria, but we can have a true diphtheria in which the membrane covers so little space that there is apparently no fibrinous exudate. This was clearly demonstrated by Jacobi in his article on '"Follicular Amygdalitis;" and every observer must have seen cases in which an apparently catarrhal follicular amygdalitis quickly proved itself to be a diphtheritic one, or. after recovery, showed its true nature by a characteristic diphtheritic sequel — a paralysis of some muscle or group of muscles. 18 274 AMERICAX TEXT-BOOK OF DISEASES OF CHILDREN. Accepting the microbic origin of diphtheria, we must still take into account the many conditions that materially modify the course of this affec- tion, Avhich is one of the most variable and uncertain of all the contagious diseases. It is doubtful if a normal mucous membrane can be infected b}- the bacillus, and it is certainly true that a lesion favors its development. This also applies to the toxalbumin of the bacterium, large amounts of which can be swallowed without danger by susceptible animals that have healthy and intact mucous membranes. Age is ordinarily an important factor in influencing the occurrence of the disease ; and, though it may occur at any time of life, it is essentially a disease of childhood. Individual or family predisposition has some influence. It occurs by marked preference in connection Avith those diseases which produce lesions of the mucous membranes. Cold and dampness favor its occurrence, partly by their tendency to excite catarrhal affections and thus offer an opportunity for infection, and partly by the more favorable conditions for the growth of the bacillus which are present during such weather. All the windows and other sources of ventilation are shut, and the rooms, especially in tenements, where the disease is most common, are stifling and hot. Insanitary conditions un- doubtedly favor the development of this germ. Klebs-Loeffler Bacillus. — In the membrane of true diphtheria this bacillus is always found, either alone or associated with other bacteria. It is rarely or never found in the blood or internal organs, although the strepto- coccus, which is often associated with it, may appear in the blood, the lymphatics, or the viscera. On the surface and the most superficial portions of the exudate the bacillus is found mixed with numerous other micro- organisms. In the middle or deeper portions the only organisms present are the Klebs-Loefller bacilli, either alone or associated with streptococci. In the deeper layers there are only a few bacilli, and in the mucous membrane, as a rule, none. These bacilli are "moderate-sized rods, usually slightly bent, averaging nearly as long as the tubercle bacilli, but twice as broad, and usually with rounded ends. According to the rapidity of growth, the soil, and other con- ditions, the form and size of the micro-organisms vary, and the differences are striking. The bacteria are sometimes enveloped in a more or less capacious membrane ; sometimes the contents divide into a number of pieces, separated by transver.se divisions ; one end of the rod is frequently thickened like a club, or both ends may be clubbed, or one or both pointed. The bacilli are immobile and have no spores. The best staining agent is Loeffler's alkaline methyl- blue. Some forms stain uniformly, others in various irregidar ways, the most common being the appearance of deeply-stained granules in a slightly-stained bacillus or of darkly-stained ends with a paler centre. The bacilli are very often in pairs, never in chains ; they are semi-anaerobic, and thrive at a somewhat high temperature, 20° to 42° C." '•The Loefller bacilli can be cultivated upon all tlie ordinary culture media, but grow most vigorously on a mixture of blood-serum and nutrient bouillon, as given bv Loefller. On this, solidified, the bacilli groAv as large, round, elevated, grayish-white colonie^^. with the centre more opatjue than the somewhat irregular periphery" (Park). The most ready method of detecting this bacillus is to detach a small piece of membrane and place it for five minutes in a 2 per cent, solution of boracic acid, then to draw the piece of membrane along the surface of sterilized blood-serum in a test-tube, and maintain it at a temperature of 37° PLATE X.

At the end of this time, if the bacilli are present, characteristic small white rounded colonies are visible along the track of inoculation. They can then be stained and examined. To get a pure culture a second or third preparation must be made. To overcome the diffi- cultv of obtaining serum for the culture medium, Sakharof suggests the use of slices of hard-boiled eggs placed in sterilized test-tubes, and Johnston sug- gests the use of hard-boiled eggs from which a part of the shell has been removed with ordinary forceps, so that the shell-membrane can be peeled off and the inoculation made at that point. To guard the culture against contam- ination, the egg can be placed upside down in a common egg-cup, the interior of which has been sterilized by allowing a flame to enter it for a second or two. The pseudo-diphtheria bacilli is a term applied to a group of micro- orcranisms which closely resemble the true diphtheria bacilli, both in appear- ance and in producing a pseudo-membrane, but they are without pathogenic properties in guinea-pigs, and they do not grow on gelatin at ordinary temperatures. However, for bedside diagnosis it is wiser to consider all cases as true diphtheria that give colonies of bacilli resembling the Klebs-Loeffler. The ptomaine, or poison, produced by the diphtheria bacillus is of a proteid nature, precipitated by alcohol and soluble in water. When pure, it is a white amorphous mass and extremely poisonous. It is not at all, or but little, absorbed by healthy and intact mucous membranes ; but when inoculated into a susceptible animal it produces all the symptoms of a diphtheria without the exudate. Mode of Infection and Propag-ation. — There is no doubt that in the vast majoritv of cases the inoculation takes place through some lesion of the mucous membrane or of the skin. Therefore, it Avould be hard to over- estimate the value, as a prophylaxis, of attention to all lesions, no matter how slight, of the mucous membrane of the upper air-passages. Every catarrhal condition should receive prompt and efficient treatment, and bad teeth, accumulated secretions, or any other source of local irritation should be removed as soon as possible. The germ is usually propagated through the surrounding air. and brought in contact with the mucous membrane during respiration. Less frequently the disease may be propagated by the direct deposition of diphtheritic matter by inoculation or through some article of food. It has been known to have been communicated from some of the domestic animals. The contagion may be spread by contact with the person or clothes of those suffering from the disease, and may also be spread by bed-clothes, furniture, and other articles in the sick-room. Too much care cannot be taken to prevent those surround- ing the sick from spreading the disease, and there is no doubt that phys- icians themselves frequently carry the disease from one patient to another. This is clearly shown from the large number of cases which occur in their own fimilies. Incubation. — In experimental diphtheria the duration of the incubation period is short, varying from twelve hours to three days ; but when diphtheria is contracted in the usual way — by inhaling air which contains the contagion — tliis period may be much longer, varying from one day up to twenty. How- ever, in the latter case this only means the interval between exposure and the appearance of the disease, for there is no means of knowing exactly when the contagion entered the mucous membrane, and how long it had remained harm- lessly upon it, waiting for the development of some lesion through which to infect it. It is obvious, therefore, that all observations based upon the inter- val between exposure and the appearance of the disease mtist be uncertain. 276 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. This period also depends not only upon the quality and quantity of the infecting matei'ial itself, but also upon the structure and texture of the tissues and their poAver of resistance — a power which is often greatly modified by strep- tococci and other bacteria which may be associated with the true diphtheria bacilli. When the Klebs-Loeffler bacilli are implanted upon a normal mucous membrane, they do not grow, but these associated streptococci produce an acute purulent discharge, with redness and swelling. Thus they prepare the lesion for infection by the Klebs-Loeffler bacilli. Anatomical Changes. — The local pathological changes of this disease occur on a mucous membrane or some abraded portion of the skin. The changes found on the inflamed mucous membrane are as follows : The surface becomes hypernemic and sAvollen, and presents the usual manifestations of a catarrhal inflammation. After a short time, usually a few hours, it is covered Avith a whitish or yellowish layer, Avhicli forms the pseudo-membrane so characteristic of the disease. This membrane may represent a fibrinous exudate which can be easily peeled from the surface beneath, or it may represent a true necrosis, so that the exudate is an integral part of the mucous membrane and cannot be separated from it. Many of its characteristics depend upon its anatomical position and the type of epithelium upon Avhicli it is located. It looks to the naked eye like coagulated fibrin, but under the microscope it is seen to consist of proliferated epithelial cells held together by a fibrinous network. In its physical and chemical properties it closely resembles fibrin. The surface beneath the exudate may show all grades of inflammation, from a mild catar- rhal to an ulcerated one. The false membrane is found oftenest on the tonsils, uvula, soft palate, and back of the pharynx, the nasal passages, the larynx, and trachea ; less commonly on the conjunctiva, at the border of the anus, or in the vagina ; rarely in the bronchi as a primary aff'ection, but not uncom- monly as an extension of the same process from the larynx and trachea ; and very rarely in the oesophagus, the intestinal tract, or the ear. Besides these local pathological changes other organs of the body may become aff"ected. as the result of the absorption of the toxalbumin. The adjacent lymph-nodes are swollen and inflamed, but they rarely become the seat of a suppurative inflammation ; the surrounding tissues are infiltrated with serum containing scattered pus-cells. The lun^rs show areas of intense congestion, with hremorrhasres into their tissue. They may exhibit oedema, broncho-pneumonia, catarrh, atelectasis, emphysema, ecchymoses, and large infarctions ; and the bronchi may be lined with false membrane as far as the smaller branches. These changes, however, are mostly observed as complications of laryngeal diphtheria. The pleura may be hypememic and inflamed, with haemorrhages, and in many cases the pleural cavity will contain an excess of fluid. The kidneys, in experimental cases, are moist and hyperaemic, and the adrenals are congested and may be h?emorrhagic. Fatty changes occur in the epithelium of the tubes and glomeruli, and hyaline alterations in the glomer- ular capillaries and in the smaller arteries. Haemorrhages, parenchymatous and interstitial nephritis, are common lesions observed in the kidneys in albu- minuric cases. The spleen and the liver may be enlarged and congested, with haemorrhages into the capsule and tissue. There may be present smaller or larger masses of necrotic cells, and in some cases there is a fatty degeneration, and occasionally, in protracted cases, a hyaline or a waxy one. The heart may show in the substance of the muscle large and small haemorrhages and ecchymoses. When death is due to .asphyxia without DIPHTHERIA. 277 general poisoning of the whole organism, the muscular substance of the heart itself may be normal ; but when there has been a general poisoning it has usually undergone a granular and fatty degeneration, and there may be other septic changes, as, for example, an endocarditis. In both the parietal and visceral layers of the pericardium there may be small and large haemorrhages and ecchymoses ; there may be an excess of fluid in the pericardial cavity ; and in rare cases there may be an emphysema of the pericardium as a consequence of the extension of a subpleural emphysema into the loose cellular tissue between the folds of the mediastinum. The blood, as in most severe forms of septicaemia and poisoning, is but slightly coagulable, sticky, brown, or rather livid, and the blood-vessels contain a greatlv increased number of leucocvtes. The mucous membrane of the intestinal tract and of the bladder may rarely become directly infected, and under such circumstances they present the characteristic pseudo-membrane and other changes which take place in the pharynx, etc. However, when secondary changes occur in consequence of general infection, cell-infiltration and htemorrhages are the usual ones, and in one reported case such extensive haemorrhage from the great omentum occurred that a considerable quantity of free blood had collected in the peritoneal cavity. The layers of the peritoneum may be injected and be the seat of ecchymoses, and the peritoneal cavity may contain an excess of serous fluid. The fibres of the muscles show degenerative changes, and the thyroid may be congested and ecchymotic. The earliest change in the brain and spinal cord is venous hyper^emia, both in the vascular linings and in the substance itself. Later in the disease come extravasations, with the subsequent softening of the surrounding tissue, and finally various degenerative changes. Extravasations into the substance of the spinal nerves have been seen, as well as granular degeneration of the nerves of the soft palate and other parts that have sufi"ered from a diphtheritic paralysis. Symptoms and Diagnosis. — The characteristic feature of the disease is the pseudo-membrane. There are cases of pseudo-membranous inflammation which are not diphtheria ; but, excluding the chronic cases and those due to great heat, as a scald, and to the application of an intense irritant, like am- monia, it is often impossible to distinguish between the true and the false diphtheria, except by a bacteriological examination. The only positive test is the presence of the Klebs-Loefiler bacillus, either alone or associated with streptococci or other bacteria. In a certain proportion of cases it is very difiicult to distinguish between the true and the pseudo-bacillus ; and in all doubtful cases, at least for the present or until inoculation experiments can be made, it is wiser to consider them as true diphtheria. Clinically, cases of follicular amygdalitis are frequently diagnosticated as simple catarrhal or puru- lent inflammations, when they are really diphtheritic. All such cases should be isolated and treated in every respect as true diphtheria until the diagnosis is made certain either by a bacteriological examination or the appearance of new evidence which will show the true nature of the disease. The diagnosis, even of a membranous inflammation, may be obscure from its location. It may be confined to the posterior nares, the larynx and trachea, or even the intestine, the bladder, or other positions where the local changes cannot be seen. The constitutional symptoms which are the result of the poisoning due to the absorption of the toxalbumin produced by the specific bacilli vary greatly, and depend not only on the amount and rapidity of the absorption, but also 278 AMERICAX TEXT-BOOK OF DISEASES OF CHILDREN. upon the susceptibility and condition of the patient. In simple and uncom- plicated cases there is usually little or no fever. The symptoms may vary from this to evidences of the most profound poisoning. The temperature may be hio'h and irregular, the pulse rapid or, in certain very fatal cases, abnormally slow. There is languor and loss of appetite, and an amount of prostration out of proportion to the fever and the local inflammation; the skin dry and hot; and, according to circumstances, typhoid symptoms may show themselves, or there mav be delirium with great restlessness. Relapses are frequent, and one attack does not protect against a subsequent one. The Ivmph-nodes which are in anatomical relation Avith the local process, as well as their surrounding tissues, may be swollen and tender, but they seldom undergo a suppurative change. The degree of enlargement and inflam- mation depends upon the amount of absoi-ption, and of course this depends not only upon the character of the local process, but also upon its relations with the neighboring lymphatics. The hearts action is usually rapid, and may be feeble, during an attack of diphtheria; and this condition often continues for some time after the disap- pearance of all local evidences of the disease. The pulse ma}^ be irregular both in force and rhythm. Another condition, usually appearing late in the disease, and often when the local process is apparently improving or has entireW cleared up. is for the feeble pulse to become progressively slower until the beats num- ber less than forty, sometimes less than thirty, to the minute. These cases, which are nearly always fatal, together with those having the feeble, rapid pulse of profound sepsis, and exhaustion, may be classed as examples of slow heart failure. But there is still another condition Avhich usually appears after all the alarming symptoms are gone; that is, a sudden failure or paralysis of the heart. Endocarditis most frequently involving the mitral valve may occur, and is accompanied by fever, priscordia'i pain, attacks of syncope, a systolic murmur, and ante-mortem heart-clots, which may become free and enter the circulation, producing the usual phenomena. In most cases there is a rapid destruction of the red corpuscles of the blood, and a relative increase of the white corpuscles. Hence the anemia which appears early and rapidly increases as the disease advances. Albuminuria is a connnon complication, and appears usually on the third to sixth day, but may rarely appear as early as the first day or as late as the fifteenth. The amount of albumin varies greatly, from a slight cloudiness, on boiling, to complete consolidation. The urine usually appears normal, but it may be scanty and dark, and in rare cases dark-colored or smoky from the presence of blood. There may also be present in the sediment gran- ular, hyaline, epithelial, and blood casts. The duration of the renal complica- tion varies from a day or two to a week or two, but it may occasionally become chronic. It is seldom attended with oedema, but vomiting and other uraemic symptoms are not so rare. It is impossible to distinguish between the albu- minuria of true and of false diphtheria, but in diphtheria there are some characteristics which distinguish it from the same complication of scarlet fever. The tonsils are the most frequent location of the disease, and when confined to them it runs a mild course, because they have little or no connection with the lymphatic system, and they do not contain a large number of bloo M. de Heilly reports a fatal case in a child in whom haemorrhage arose from an ulceration of the trachea, which had extended to the innominate artery, aAd was 20 306 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. caused by the end of the tracheotomy-tube. Dr. Hutton reports a similar case in which death occurred from hcTemori'hage ; and several other cases, in which the innominate artery was opened in the same manner, have been recorded. If the bleeding arises from smaller vessels, it is often possible to control it by the application of ligatures or by the use of the galvano-cautery ; but haemor- rhage from the innominate artery is so profuse that it has always rapidly proved fatal before any attempt could be made to control it. Surgical emphysema, starting from the region of the wound, is occasionally met with after tracheotomy : the presence of air in the tissues is explained by the fact that during the violent inspiratory efforts in obstruction of the larynx there is more or less of a vacuum produced in the chest, and the air is sucked into the cellular tissues of the neck and diifused throughout the tissues gener- ally. It is said to be more common after tracheotomies in which the incision in the treachea is not in the median line and does not correspond with the wound in the soft parts in front of the trachea. A moderate amount of emphysema in the immediate neighborhood of the wound is not uncommon, but sometimes the condition is developed to such an extent that the cellular tissues of the neck, face, arms, chest, and abdomen become greatly distended with air. I once saw a case in Avhich these parts were all involved, and the crepitation of the air in the cellular tissue at the ends of the fingers could be distinctly felt. In this case there was also recurrent dyspnoea, which was probably due to mediastinal emphysema. Champneys has reported 28 cases in which autopsies had been made after tracheotomy, in which the operation was performed for diphtheritic laryngitis. In 16 of these cases emphysema of the mediastinum Avas present. This condition has also been found in patients dying from diphtheria in whom tracheotomy had not been performed. Emphysema, when developed to a moderate extent, seems to do no harm, as the air is usually quickly absorbed ; but when it becomes general and the mediastinum is involved, marked dyspncea is apt to develop and the prognosis is extremely grave. Granulations about the tracheal wound occur in certain cases where there seems to be a peculiar hypersensitive condition of the mucous membrane of the trachea. These granulations are most commonly seen in cases where tubes have been worn for a long time, and are often one cause of difficulty in their permanent removal. The presence of granulations may be suspected if the child coughs up blood-stained secretions after the tube has been changed. Withdrawal of the tube and inspection of the wound will often disclose the presence of granulations attached to the edges of the tracheal wound or grow- ing from the trachea in the region of the wound. The treatment of this con- dition consists in the application of a 30-grain solution of nitrate of silver ; or they may be touched Avith a solid stick of nitrate of silver; or the wound may be freely exposed by the introduction of a tracheal dilator, and the granula- tions seized with forceps and removed with scissors, or scraped away with a curette. Ulceration of the trachea may arise from improperly-shaped or badly-fitting tracheotomy-tubes ; it may be suspected when the tube, if a silver one, becomes blackened, and there are fetor of the breath and expectoration of purulent and blood-stained dischai'ge. This complication is not so apt to occur at the present time under the use of the improved tracheotomy-tubes which are now employed. The treatment of this condition consists in first removing the badly- fitting tube and replacing it by a properly-fitting one, and, further, in the appli- cation to the ulcerated surface of a 10-grain solution of nitrate of silver. Difficulties in the Permanent Removal of the Tracheotomy-tube. — In the great majority of cases the tracheotomy-tube can be permanently dispensed TRACHEOTOMY. 307 with in from eight to fifteen days, yet there are occasionally met instances in which this cannot be accomplished for months or even years; a few cases have been recorded in which its final removal was never satisfactorily accomplished. The difficulty of the permanent removal of the tracheotomy-tube is due, in some cases, to mechanical causes, such as the growth of granulations in the trachea or wound or in the larynx, inflammatory hypertrophy of the vocal cords, adhesion between the cords, paralysis of the posterior crico-arytenoid muscles, spasm of the glottis, or stenosis of the trachea at the seat of operation. Dr. Emil Kohl, in an exhaustive article upon this subject, mentions, as also causes of delay or difiiculty in removing the tracheotomy-tube, prolonged diphtheria, re-formation of the diphtheritic membrane, changes in the shape of the trachea or larynx from the operation or from the wearing of the tube, and relaxations of the anterior wall of the trachea. Where the difiiculty in the permanent removal of the tube is due to the presence of granulations in the trachea or larynx, after their removal by some of the methods before mentioned the phy- sician is usually able to dispense with the tube. Where stenosis of the trachea or larynx exists and prevents the permanent removal of the tube, the parts may be gradually dilated by the use of bougies, or, better, by the introduction of an intubation-tube after the removal of the tracheotomy-tube: the Avound in the neck can then be plugged with a nipple attached to a shield (Fig. 6), or with Fig. 7. Fig 6 ^ ^fi^ Obturator for Tracheotomy Wound. Obturator for Tracheotomy Wound. an instrument shown in Fig. 7, to keep the Avound from healing until it is cer- tain that there will be no necessity for the reintroduction of the tracheotomy- tube. The intubation-tube may be worn for some days or weeks, and then re- moved, and if the breathing is satisfactorily carried on with the wound in the neck plugged, as above described, the shield with the nipple may be removed, and the wound be allowed to heal. By this method of treatment I have been able to finally remove tracheotomy-tubes which had been worn for a long time. I have had recently under my care a child of eighteen months of age in whom I was only able to remove the tracheotomy-tube permanently after sixty days by the use of an intubation-tube and obturator; and another case where a patient was finally able to dispense with a tube after having worn it for four years. In young children I have seen difiiculty in the permanent removal of the tube from the fact that the trachea is very flexible, and from the fact that the wound in the soft parts in healing had become attached to the tracheal wound, and in inspiration assumed a valvular form, allowing little air to enter the trachea. If the tracheotomy-tube is removed before the larynx is clear, or while there is irregular action of the laryngeal muscles, dyspnoea soon becomes marked and necessitates its reintroduction. This can best be overcome by removing the tube from time to time, and trying to induce the child to learn again to breathe 308 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. througli the larynx, or by introducing the intubation-tube for a time, and keep- ing the tracheal wound from healing until the breathing is again satisfactorily accomplished through the larynx. Mr. Thomas Smith has shown that tracheotomy is apt to cause undue irri- tability and disorderly action of the muscles of the glottis, so as to interrupt their usual rhythm. Cohen says that the explanation of this phenomenon resides in the fact that the laryngeal muscles have lost their habit of contract- ing harmoniously with the needs of respiration, the patients being somewhat in the condition of those with paralysis of the vocal cords. Some pa- tients can breathe comfortably without the tracheotomy-tube except during sleep. In explanation of these cases Mr. Thomas Smith suggests that the influence of the will may be necessary to regulate and secure due action of these muscles, the perfection of whose movements has been impaired, and that on this account inspiration through the larynx during sleep is impos- sible. Mental agitation plays an important part in preventing the removal of the tube in many cases, for we often see children who can breathe comfortably through the larynx when the tube is plugged, but who, when it has been removed and the tracheal wound has been closed with a pad or obturator, exhibit great mental agitation and develop such alarming symptoms of dyspnoea that the reintroduction of the tube becomes necessary. It is remarkable to observe how even a young child soon learns to depend upon the presence of the tube for breathing, and how he will resist its removal ; he will often get into such a rage if it is withdraAvn, that the rhythmical respiratory action may become so seriously embarrassed as to require its immediate replacing. Cases have been recorded where, even after the wound had healed, children could breathe comfortably only by having the tracheotomy-tube tied around the neck. Stevenson has made the observation that fright, upon the removal of the tracheotomy-tube in children, produces a nervous, excitable condition, irregular respiration, and sobbing, seeming to induce spasm of the glottis. The permanent removal of the tube, if there be no mechanical difficulty present, can usually, in most cases, be finally accomplished by gaining the confidence of the child, and by patience and perseverance in withdrawing the tube at intervals of gradually increasing length. Post-tracheotomic Vegetations. — Under this title there have been described vegetations or granulations which occur in the trachea after the wound has cicatrized. These growths are more apt to occur in male children, and appear fifteen days to a month after the wound has healed. The most marked symptoms of this aifection are embarrassed respiration with progres- sive dyspnoea. The first case of this kind was reported by Gigon, aud since that time fourteen cases have been collected by Ross. Denger reported a case which died two Aveeks after the wound had healed, and in which an autopsy revealed a tumor of granular tissue in the trachea at the seat of the trache- otomy wound. The treatment of these growths consists in again performing tracheotomy, exposing them, and removing them with scissors or knife, cauterizing their bases, and introducing the tracheotomy-tube ; if, after a short time, they show no tendency to recur, the tube should be removed and the wound alloAved to heal. Tracheotomy without Tubes. — Some surgeons, recognizing the amount of attention which patients require while wearing tracheotomy-tubes, and possibly over-estimating the dangers in their use and the difficulty which is sometimes experienced in their final removal, have recommended and prac- tised the operation of tracheotomy without the use of the tube. Dr. Martin TBA CHEO TOMY. 309 has reported several cases in which he dispensed with the tracheotomy-tube, the edges of the tracheal wound being fastened to the skin by sutures. Other surgeons have recommended the removal of a small jjortion of the trachea on each side of the incision when no tube is to be used. I think there is little danger in the use of the tracheotomy-tubes which are now employed, if the precaution be taken to see that they fit the trachea well. The objection that more care is required in the after-treatment of the case while wearing the tube is not a valid one, as it seems to me that an equal amount of attention is required whether the tracheotomy-tube be used or dispensed with. The removal of a triangular portion of the trachea from each edge of the wound I do not recommend, as stenosis of the trachea at the point of operation is apt to result. The number of cases in which the use of a tracheotomy-tube has been entirely dispensed with has been so small that we cannot yet fairly judge of the value of the procedure. Personally, I am decidedly of opinion that the use of a well-fitting tube is a most important factor in a case of tracheotomy, and as such would most strongly recommend its employment. Thermo-cautery in Tracheotomy. — The dread of haemorrhage has led certain surgeons to substitute a thermo-cautery knife for the scalpel in the operation of tracheotomy. In 1870, Amussat first employed the galvano-cau- tery in tracheotomy, and this method also has been employed by Verneuil, Krishaber, and others. Rapid Tracheotomy. — Fear of troublesome hgemorrhage has not deterred some surgeons from recommending a rapid tracheotomy by a single cut. Saint Germain claims to have performed a number of such operations without a single serious accident. Mr. Durham has recommended a rapid tracheotomy, which he performs in the following manner : The surgeon stands upon the right side of the patient, and places his forefinger on the left side of the trachea and his thumb on the other side, so as to include between them the spot at which the trachea is to be opened. Firm pressure is made, and the trachea can be felt between the thumb and finger ; the safety of the great vessels is ensured, as they are outside of the line of incision. By a succession of careful incisions the operator cuts down on the trachea, and when it is exposed he may open it directly or fix it with a tenaculum before opening it. Mr. Durham claims to have operated on a number of cases without any untoward results. This rapid method of performing tracheotomy has not been very generally employed, and I cannot appreciate its superiority over the slower and safer method of dissect- ing carefully down to the trachea and opening it, except in certain rare cases of great urgency. I therefore am of the opinion that rapid tracheotomy will never supersede the latter operation, which has the advantage of enabling the surgeon to recognize and avoid structures the wounding of which would be dangerous. Condition of Patients after Recovery from Tracheotomy. — The con- dition of patients after recovery from tracheotomy performed for diphtheritic or membranous laryngitis is a matter of great interest. As far as my personal observation goes, the voice in these cases seems to be unimpaired, and they do not seem to be more liable to laryngeal affections than those in whom recovery has occurred without operative interference. The rare occurrence of post- tracheotomy vegetations has been already referred to. Drs. Lovett and Munroe have made some very valuable observations bearing upon this subject: in 56 cases where tracheotomy had been performed more than a year previously, which they investigated with reference to the effect of the operation upon the voice and general health of the patient, 53 were in good health, and none of 310 AMERICAN TEXT-BOOK OF DLSEA/^ES OF CHILDREN. them had had a second attack sufficient to call for surgical aid. The voice was clear in all but 4 cases ; 6 patients were liable to sore throat ; 3 were not in good health, 1 having phthisis, but without any laryngeal symptoms, 1 had a hoarse and croupy voice, and the third was 'a delicate boy who was con- stantly ill. INTUBATION OF THE LARYNX. By henry R. WHARTON, M. D., Philadelphia. Intubation of the Larynx is an operation by which a metallic tube is passed through the mouth into the larynx for the relief of dyspnoea resulting from laryngeal stenosis. This procedure for the relief of dyspnoea depending upon croup was first employed by Bouchut of Paris in 1858. He used a hollow metallic cylinder about an inch in length, which was pressed into the larynx and allowed to remain, and had attached to it a silken thread to facilitate its removal and to prevent its passing down into the trachea. Although, as far as known, this was the first formal method of treating dyspnoea in cases of croup by the introduction of a metallic tube into the larynx, the procedure of introducing a tube into the larynx to relieve dyspnoea arising from other causes, known as catheterization of the larynx, had been employed by many surgeons before this time. The results of Bouchut's cases were not sufficiently satisfactory to recommend its general adoption, and the procedure fell into dis- use. Dr. Joseph O'Dwyer of New York, in 1880, after numerous experiments upon dead subjects in the autopsy-room of the New York Foundling Asylum, finally reintroduced this operation as a means of dealing with dyspnoea result- ing from laryngeal stenosis. Numerous modifications of the tube were made, and it is due to the patient and careful work of O'Dwyer that the operation has become recognized by the profession as a legitimate procedure in the treat- ment of the symptoms arising from laryngeal obstruction. The operation of intubation of the larynx, which has been employed in many thousands of cases in this country and abroad, has now taken its place with tracheotomy as a well- recognized surgical procedure in the treatment of obstructive dyspnoea. Indications for Intubation. — The indications for intubation of the larynx in cases of diphtheritic or membranous croup are similar to those which are recognized as indications for the operation of tracheotomy in the same aff"ec- tion — namely, labored breathing, retraction of the lower ribs and supracla- vicular spaces, retraction of the tissues of the suprasternal notch, cyanosis, rest- lessness, inability to sleep, or, in other words, marked symptoms of obstructive dyspnoea. Prognosis in Intubation. — An examination of large numbers of reported cases of intubation of the larynx shows that the number of recoveries follow- ing the operation is very similar to the number following tracheotomy. Ball, in a collection of 4217 cases of intubation gathered from American and Euro- pean sources, found that there were 1285 recoveries, or about 30.4 per cent. Ball also presents some statistics bearing upon the age of the patients. In a total number of 1540 cases, tabulated according to age, there were 474 recov- eries, or 30.7 per cent. The percentage of recoveries at each age is shown in the following table : 311 312 AJIERICAX TEXT-BOOK OF DISEASES OF CHILDREN. 60 cases under 1 vear of age, 11 recoveries, or 18.3 253 " " 2 veai-s of age, 48 " or 19.0 SOfi " " 3 ■ " 67 " or 21.9 306 326 231 127 83 80 26 23 7 7 11 6 7 8 9 10 11 12 over 12 67 98 93 48 37 41 13 7 3 4 4 or 19.0 or 21.9 or 30.0 or 40.0 or 37.8 or 44.5 or 51.2 or 50.0 or 30.0 or 42.8 or 57.1 or 36.3 per cent. From the above table it will be seen that intubation gives better results than tracheotomy in the first and second years of life ; from this age the difference between the two operations, as far as recoveries go, is not very marked. It must be remembered, however, that the statistics of intubation as compared with tracheotomy are not entirely to be relied upon, for many operators per- form intubation at a time when the dyspnoea is not extremely urgent, whereas the same operator would hesitate to recommend tracheotomy ; so that it is prob- able that many of the milder cases are intubated, whereas many of the very urgent ones are reserved for tracheotomy. Instruments required for Intubation. — Instruments required for intu- bation are : Intubation-tubes of various sizes. An introducer. An extractor. A mouth-gag. A gauge. Fine braided silk. The intubation-tubes (Fig. 1) for children are usually six in number, of different sizes, adapted to children from one to twelve years of age. The tube Fig The Intubation-tube and Introducer. now generally employed consists of a metal cylinder which bulges near its centre, and is provided with a collar or head to rest upon the false vocal cords ; it is irregularly quadrangular, one angle resting between the arytenoid car- tilages, and its opposite angle bevelled so as to better allow of the closure of the epiglottis over the aperture of the tube ; the tubes are gold-plated, and each is provided with an obturator, which has a blunt extremity. Just below the head the tube is of small diameter to avoid injurious pressure on the vocal INTUBATION OF THE LARYNX. 313 cords. About midway the wall of the tube is increased to its greatest diame- ter, which bulging serves to maintain it in position during coughing and increases the weight to be expelled. Through the edge of the collar on each tube there is a small perforation through which the strand of fine braided silk is Fig. 2. passed, which serves to remove the tube if in its introduction it should be passed into the pharynx or oesophagus instead of the larynx, or if from sudden ob- struction it has to be hurriedly with- drawn. The introducer (Fig. 1) consists of a handle and a staif which is curved to a right angle at its extremity, which has a screw that attaches it to the Fig. 3. Mouth-gag. The Extractor. obturator, and a sliding gear for detaching the obturator from the tube when it is placed in the larynx. Mouth-gags of various kinds may be used : the one generally supplied with intubation sets is that shown in Fig. 2, which is a self-retain- ing instrument. The extractor is also curved on a right angle, and has at its extremity a small forceps with duckbill blades, which are made to separate and apply themselves to the interior surface of the tube with sufiicient firmness to withdraw it (Fig. 3). The gauge is to determine from the age of the child the size of the tube to be employed (Fig. 4). Preparations for Intubation. — It is important that the fol- lowing preparations should be made, so that the actual introduc- tion of the intubation-tube may occupy as little time as possible, for it should be remembered that when the intubation-tube enters the larynx breathing is arrested until the obturator is removed, and therefore everything should be in readiness and all manipulations should be as rapid as consistent with accuracy. The time usually required after the mouth-gag has been adjusted for the introduc- tion of the intubation-tube and withdrawal of the obturator is from five to ten seconds. Before attempting to introduce an intubation-tube the surgeon should select a tube of suitable size for the age of the patient, and should have a strand of fine braided silk about two feet in length passed through the eyelet and secured with a knot. Having attached the tube by means of the obturator to the introducer, he should next see that it can be freed from the obturator by working the trigger. The mouth- FiG. 4. "^ii'2i— E>^i Vm- IIIJBEilllii Gauge. 314 A3IERICAN TEXT- BO OK OF DISEASES OF CHILDREN. gag should also be examined to see tliat it is in proper working order, and this, with the tube and introducer, should be placed in a basin of warm water. The surgeon should next protect the index finger of the left hand, which is to be passed into the mouth of the patient, by wrapping it for an inch or an inch and a half in the region of the second joint with rubber or adhesive plaster, or a metal shield may be employed. This is an important precaution to prevent the patient from biting the finger in case the mouth-gag should slip, for a bite from the teeth, which are often very foul in these cases, is liable to be followed by serious consequences : a case has been recorded of a fatal result following such an injury received while performing intubation. Position of Patient for Intubation. — The child should be taken upon the lap of the nurse and wrapped in a blanket, which should swathe it from the neck to the heels, and the nurse should grasp the child's elbows outside of the blanket and hold them firmly, but should not press them against the chest in such a way as to embarrass the respiratory movements ; at the same time the legs of the patient are secured by being held between the knees of the nurse. The head of the patient should next be secured by being held between the open hands of the assistant placed upon the sides of the head and cheeks ; the left hand of the assistant may also be used in steadying the mouth-gag after it has been introduced (Plate XII). The patient should be held straight, and should not be allowed to lean back so as to get out of the operator's reach. Northrup well describes the proper position of the child for intubation when he says : " The position of the child should be as though it hung from the top of the head." This is un- questionably the best position in which to place the child for intubation, but it is possible to introduce the tube with the child in the recumbent posture : this I have done on several occasions when, from the condition of the circula- tion, I did not think it advisable to lift the child to a sitting posture ; and in the Boston City Hospital, Dr. Lovett reports that intubation has also been per- formed in a number of cases with the patient supine ; but under ordinary cir- cumstances the position described above will be found most convenient. Operation of Intubation. — The child being held as described above, facing the surgeon, who sits upon a chair within easy reach of the patient, the assistant fixes the head, and the surgeon opens the mouth and introduces the blades of the mouth-gag between the molar teeth on the left side ; the blades are next opened by compressing the handles of the gag, and the assist- ant should then hold the gag steady Avith the fingers of the left hand. Chil- dren often struggle at this time and resist the introduction of the mouth-gag • hence it is better to open the jaws with the handle of a spoon introduced between them, even with the exercise of some force, and to introduce the gag, than to allow the child to become exhausted by struggling against ineffectual attempts to introduce it without the use of force. When the mouth has been opened the surgeon passes the index finger of the left hand into the pharynx and feels for the epiglottis, which is hooked forward by the end of the finger. The tube attached to the introducer is next passed into the mouth and carried back to the pharynx, the operator being careful to see that it hugs the base of the tongue in the middle line, that the handle is depressed well upon the child's chest, and that the silken thread is free. When the extremity of the tube comes in contact with the end of the finger holding the epiglottis, the handle should be raised as it engages in the larynx and descends into this organ ; and as it is pushed downward into place the finger is placed upon the head of the tube to fix it and prevent its being withdrawn with the obturator ; the trigger is next pressed, and the introducer and obturator are drawn from the mouth by depressing the handle PLATE XII. INTUBATION. (Inserting the Tube.) INTUBATION OF THE LARYNX. 315 . upon the chest, and at the same time the tube should be pressed well down into the larynx with the finger which rests upon its head. A caution should here be given as to the importance of using little force in pressing the tube home after it engages in the larynx : no more force should be used than in passing the catheter or bougie into the urethra ; and if it is found that the tube is too large to be passed into the larynx without the exercise of great force, it should be withdrawn and a smaller one attached to the instrument and introduced. As soon as the obturator has been withdrawn the child makes a deep inspiration : at the first expiratory efi"ort there is generally coughed up false membrane or muco- purulent matter, and when the tube has become cleared of this the respiration is usually satisfactorily carried on. If, on the other hand, after withdrawing the obturator, the dyspnoea is not relieved by the expiratory efibrts of the child, the tube should be removed by means of the thread and examined. If its canal is clear, showing that no mass of membrane is occluding it, and the dys- pnoea does not decrease, it is pretty good evidence that the obstruction exists below the point to which the intubation-tube extends : it is therefore better to make no further attempt to introduce the intubation-tube, but to perform tracheotomy promptly. Before removing the mouth-gag it is well to intro- duce the index-finger of the left hand to feel that the tube is in place and has not been disturbed by the coughing efforts. The management of the silken thread attached to the tube is a matter of some importance. Some operators, as soon as the tube is properly placed, cut the loop of thread, and. with the finger resting upon the head of the tube, pull upon one end of the loop and withdraw it. This is done to relieve the irrita- tion of the fauces which the thread sometimes causes, and to prevent the child seizing it and pulling out the tube. Other operators prefer to leave the thread in place for some hours or days, securing the loop around the ear so that it can- not become loose ; and in the event of the tube becoming blocked with mem- brane and not being coughed out, it can be removed by traction upon the thread. To prevent the irritation of the fauces and 2:a£D;incr which the thread sometimes causes, it may be passed through the posterior nares and brought out at the anterior nares, and secured to the ear or the face by a strip of plas- ter. I usually leave the thread in place for twelve or twenty-four hours, bring- ing it out of the mouth and attaching it by the loop around the ear, and placing a few strips of adhesive or rubber plaster over the thread from the ear to the angle of the mouth, to prevent the child grasping it and displacing the tube. Where it is possible, I also pass the thread between the molar or premolar teeth to prevent the child from biting it in two. TThen the child shows a tendency to grasp the thread, it is well to enclose the hands in stockings and secure them around the wrists. It is quite possible in introducing an intubation-tube to pass it into the pharynx ; and if this happens, as soon as the obturator is withdrawn the error is discovered and the tube should be removed and reattached to the introducer, and another attempt made to pass it into the larynx. This error, I am sure, often occurs in the hands of inexperienced operators by not being careful to hug the base of the tongue closely with the end of the tube, by not keeping strictly in the median line, and by disregarding the position of the tip of the index finger of the left hand, which is held in contact with the epiglottis and is a guide to the opening of the larynx. Accidents during- and after Intubation. — It is well for the operator to remember that certain accidents may occur during the operation of intubation, such as pushing a mass of membrane down into the trachea before the tube, or a too deep insertion of the tube, so that its head passes below the vocal 316 A2IERICAN TEXT-BOOK OF DISEASES OF CHILDREN. cords: these accidents have been reported, but I must confess that I have never had a serious accident occur during the operation. The pushing of a mass of membrane down before the tube is likely to embarrass the respiration so seriously that in the violent respiratory efforts of the child the tube is apt to be forced out of the larynx ; if the tube is not forced out, it should be removed by means of the thread, and if the respiration is still embarrassed, tracheotomy should be resorted to. The accident of pushing the tube too deeply into the larynx is not likely to occur if a proper-sized and proper-shaped tube is em- ployed. A tube which is too small may be easily forced between the vocal cords, or may be draAvn downward by the inspiratory efforts of the child. Should this accident occur, the tube can usually be removed by traction upon the thread, and if a subsequent downward displacement occurs after the removal of the thread, it would be necessary to perform tracheotomy for its removal. Several instances have been reported in which this accident occurred and a resort to tracheotomy was necessary. In certain cases, after the tube has been retained for a few days, it is coughed up, and upon being replaced the same accident occurs : a larger tube should then be tried, and if it cannot be tolerated by the larynx, further attempts at intubation should be desisted from, and, if dyspnoea is still marked, tracheotomy should be resorted to. Another accident which sometimes occurs is the coughing up and swallowing of an intubation-tube which is not attached to a thread. The tube is usually passed through the ali- mentary canal without difficulty, and I know of no fatal result following the swallowing of an intubation-tube. Although I have never personally seen any accident happen during the operation of intubation or while the intubation-tube was in place, I always have at hand during the operation my tracheotomy case, so that I can promptly open the trachea if the indication exists, and would advise all operators to be similarly prepared. After-treatment of Cases of Intubation. — Cases in which an intubation- tube has been introduced require most careful watching by a nurse who is com- petent to meet any emergency that may arise. If dyspnoea suddenly develops from the obstruction of the tube by a piece of membrane too large to pass, the nurse should be instructed to remove the tube, if the thread is still attached ; or if the thread has been withdrawn she should invert the child, and by striking over the posterior portion of the chest she may be able to dislodge the tube. A case has been recently reported in which this manipulation by the nurse saved the patient's life. In the after-treatment of cases of intubation I have great faith in the efficacy of steam spray of Parker's soda solution (p. 302) or a spray of peroxide of hydrogen for its effect in dissolving membrane and lique- fying the secretions. I usually have the spray used every half hour, or more frequently if there is little tendency to expectoration ; in cases described as dry the use of the spray, I think, is most important. Feeding of Intubation Cases. — The most difficult portion of the after- treatment of cases of intubation is the satisfactory feeding of the patient. From the interference with the act of deglutition caused by the presence of the tube and the imperfect action of the epiglottis, liquid nourishment is apt to pass into the larynx and set up coughing, which interferes with the taking of a sufficient quantity of nourishment. As many cases in which this operation is employed require large quantities of food from the nature of the disease for which the operation is performed, I think the difficulty of properly nourishing the patient constitutes the most serious objection to this operation. Children, as a rule, while wearing an intubation-tube, have difficulty in swallowing liquids, but there are occasionally seen cases in Avhich liquids are swallowed without difficulty ; therefore it is well to make a trial as to the feeding before PLATE XIII. METHOD OF FEEDING INFANT AFTER INTUBATION, WITH THE HEAD LOWER THAN THE BODY. INTUBATION OF THE LARYNX. 317 a special diet is ordered for any individual case. It is remarkable to observe how some children -wearing intubation-tubes will learn to swallow with the tube in place. I have seen children who at first were unable to take liquid nourishment in a few days change their manner of swalloAving, so that liquids could be taken without discomfort. If upon trial, it is found that there is difficulty in swallowing liquids, I first order a diet of semi-solids, such as corn- starch, mush, milk-toast, rennet, puddings, soft-boiled eggs, and, as patients soon experience thirst, I order for them pieces of ice to be swallowed, or give enemata of water, an ounce to an ounce and a half, repeated at intervals. In young children, in whom a milk diet is essential, it will often be found that the child can swallow well if fed from a nursing-bottle, the head being dropped over the nurse"s lap, so that it is lower than the body (Plate XIII). This useful expedient was suggested by Casselberry of Chicago, who found that with the patient supine and the head lower than the body fluids could not pass into the larynx, but would be forced up the oesophagus into the stomach. If, however, all expedients fail as regards methods of feeding, as will be found in some cases, recourse must be had to the introduction of food by nutritious enemata. Removal of Intubation-tubes. — The tube usually remains in place for some days, and is often coughed out as the swelling of the laryngeal tissues subsides. If the breathing is carried on satisfactorily, it need not be re- placed ; but it is well to remember that for a few days the dyspnoea is liable to return, so that the reintroduction of the tube may be necessitated ; and the surgeon should be within reach during this time. If the tube has not been coughed out and the child's general condition is improved, the temperature having a tendency to reach the normal mark, at the end of three or four days I usually remove the tube ; and if there is no return of the dyspnoea I do not reintroduce it, but have the case carefully watched, for the patient is not safe from recurrent dyspnoea for two or three days. If dyspnoea be present upon the withdrawal of the tube, I replace it promptly, and do not make another attempt at its permanent removal for two or three days. Usually in from five to ten days it can be dispensed with, although I have recently had a case in which the tube could not be permanently removed until the fifteenth day. After the expulsion or removal of the intubation-tube I continue to use the soda spray for two or three days, and the child must be carefully watched, so that it is not exposed to cold. I have noticed that in all cases in which recovery has followed intubation of the larynx there was present a considerable amount of hoarseness of the voice ; but this in a few weeks finally disappears. As the same intubation-tube may be used in many different cases, I think it most essential that every tube which is used should be thoroughly sterilized as soon as it is removed from the patient by being cleansed and boiled for a few minutes. The removal of the intubation-tube is, I think, often more difficult than its original introduction. The child should be placed in the same position as described for its introduction ; the mouth-gag should be used to separate the jaws ; the index finger of the left hand, being protected, should be passed into the mouth and placed upon the head of the tube ; the extractor should then be passed into the mouth, and with the finger on the head of the tube as a guide, the blades should be passed into the opening of the tube. The tube is grasped by pressing the lever which separates the blades, and, having a firm hold upon the tube, it is withdrawn by depressing the handle upon the chest of the patient. It is sometimes difficult to pass the blades into the opening in the tube, and during the withdrawal the blades may slip, losing their hold upon the 318 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. intubation-tube. If this accident occur, the tube can usually be hooked out of the mouth by the finger, Avhich should follow it during its withdrawal. Intubation of the larynx has added another very valuable surgical pro- cedure to the treatment of dyspnoea arising from diphtheritic or membranous laryngitis and oedema or spasm of the glottis, and, although it does not entirely supersede the operation of tracheotomy in all cases, it is now employed in many cases where tracheotomy was formerly resorted to. Cases which seem to me favorable ones for intubation are those of membranous or diphtlieritic laryngitis, Avhere the obstruction comes on rapidly, and is probably largely due to oedema of the mucous membrane of the larynx. Children under two years of age are usually better subjects for intubation than for tracheotomy. Intubation also seems well adapted for cases of dyspnoea due to oedema of the larynx from burns or scalds or from the swallowing of corrosive liquids or the inhalation of irritating gases, unless there is at the same time marked oedema of the epiglottis and fauces. Cases unfavorable for intubation are those of diph- theria, in which there is much swelling of the tonsils and fauces, with profuse deposit of membrane ; also those in which the dyspnoea comes on slowly, point- ing to a gradual deposit in the larynx of a well-organized membrane. The great advantages offered by intubation are, that the operation itself is com- paratively free from danger, it is a bloodless operation, and the consent of the parents for its performance can usually be obtained without difficulty; the inspired air enters the lungs warm and moist; and if this operation fails to relieve the patient it does not preclude a subsequent tracheotomy. Although some statistics have been presented from the Boston City Hospital showing that the prognosis in cases of tracheotomy after intubation is not favorable, my personal experience has been diiferent, for I have resorted to tracheotomy in a number of patients in whom a fair trial of intubation had failed to relieve the dyspnoea, and the results following the operation were in no wise less satis- factory than those in which tracheotomy had primarily been performed. Intubation in Stenosis of the Larynx. — The introduction of an intuba- tion-tube for the purpose of relieving chronic stenosis of the glottis has been employed successfully in many cases; it has been proven that the tube in these cases can be worn for a considerable time without harm or inconvenience. It has been employed in cases of chronic syphilitic stenosis, in cases where there is difficulty in dispensing with the tracheotomy-tube from granulations growing in the region of the tracheal wound (see p. 308), in cases of cicatricial stenosis, swelling of the mucous membrane of the larynx below the cords, bilateral paralysis of the abductors, paresis of the cords from disease, or where there is dread of having the tracheotomy-tube removed. In such cases the manipula- tion for the introduction of the intubation-tube is similar to that in acute cases, with probably the difference that more force is justifiable in the introduction. The tube should be changed at intervals, a larger size being required from time to time. In chronic cases little difficulty is usually experienced in feeding the patients, as liquids are generally taken without difficulty after the first day or two. PART lY. GENERAL DISEASES NOT INFECTIOUS MALARIAL FEVER. By W. S. THAYER, M. D., Baltimore. Synonyms. — Intermittent fever ; Swamp or Marsh fever ; Paludism or Paludal fever ; Fever and ague ; Chills and fever. The term "malaria," which has been applied in a general way to a variety of febrile and non-febrile processes, must now be limited to a certain definite class of febrile affections which we know to have a specific infectious origin. The specific micro-organisms which are the cause of these processes belong to the class of protozoa and inhabit the blood of the infected individual. Etiolog-y and Pathology. — The geographical distribution of the malarial fevers is a point of considerable interest, particularly inasmuch as it is not entirely constant. In Europe, France, Germany, and England are compara- tively free from malarial fever, while in Southern Russia and Italy the disease is very frequent. In many parts of Africa and India some of the severest forms of malaria are seen. In this country there are various localities in which malaria is endemic, particularly in certain regions in the Southern States, in Louisiana, Mississippi, Arkansas, and Texas. In the low, marshy lands along the coast throughout the Southern and Central States thei'e are many places in which malarial fevers are common. In parts of New England malaria also occurs, particularly in the Connecticut Valley, while of late a considerable number of cases has been seen along the course of the Charles River in Massachusetts. In New York City the disease is rare, though certain low- lying districts in the neighborhood give rise to a number of cases. In Phila- delphia the disease is perhaps more frequently seen, but most of the cases in that city come from outlying districts. In parts of Baltimore also malarial fever occurs, though a great majority of the cases come from the districts bor- dering on Chesapeake Bay. In the Western States malaria is less common, but in certain parts about the Great Lakes it is more or less prevalent. A very interesting point in connection with the geographical distribution of malarial fever is the manner in which the disease wanders from one region to another, diminishing greatly in intensity or almost dying out in a district where it has formerly been endemic, and developing perhaps in a region where it has been for many years an unknown disease. An instance of this is the appearance during the last five or six years of malarial fever along the basin of the Charles River in Massachusetts, where it had been for many years unknown. Again, in districts in which malarial fever has for years been endemic there seem to be cycles in which the intensity of the process increases and diminishes. Malarial fever is particularly prevalent in low, swampy, and badly-drained districts, and especially in areas which are rich in vegetable matter and have 319 320 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. been allowed to fall out of cultivation. It is much more prevalent in tropical or semitropical regions, and is more severe in climates where the moisture is considerable. It has been thought that winds have possibly some connection with the carrying of the contagion ; for instance, in some malarial districts the residents on one side of a stream may be relatively free from the disease, while those upon the other side, toward which the prevailing Avinds blow, may suffer considerably. The danger of contracting malarial fever is apparently greater among those living in the lower stories of a house than in the upper. In temperate climates the frequency of the malarial fevers varies greatly with the seasons. The majority of cases occurs in the late summer and fall, though a certain number develops in the spring and early summer, while in the winter it is very rare. In tropical climates, where the disease occurs all the year round, the greater number of cases is seen in the fall and spring months. The Specific Micro-organism. — All our accurate knowledge of the causal element of malarial fever dates from the discoveries of Laveran in 1880. While studying malarial fever in Algiers, Laveran discovered certain pig- mented bodies in the blood of aifected individuals. These bodies had long been observed by others, and by some accurately described, and even pictured, but, while the older observers considered them to be altered blood-corpuscles, Laveran recognized them as parasites, and asserted that they were the definite exciting agent of malarial fever. These discoveries have been confirmed by numerous other observers in Italy, the United States, Russia, Germany, and India. In this country Councilman, Abbott, Osier, James, and Dock have made valuable observations. Laveran and his school have published careful and accurate descriptions of the different forms of the parasite, which may be seen in the blood, but they assert that they are unable to associate any definite types of organism with distinct types of fever. From the observations which have been made, however, by the numerous Italian observers, led by Golgi, there can be to-day little doubt that certain definite types of the organism are associated with certain definite types of fever. In this country, as in Italy, there are several main types of fever : (1) The milder forms of intermittent fever, which form the great majority of the cases in the spring and early summer, but which occur at all malarial seasons : (a) tertian and double tertian (quotidian) fever ; (b) quartan fever, with its combinations. (2) The more severe, often more or less irregular, fevers which occur here, as in Italy, more commonly in the later summer and fall — the gestivo-autumnal fevers of the Italians, the tropical malaria of the Germans. This type of fever includes the so-called remittent malarial fevers as well as most of the cases of pernicious malaria and of the malarial cachexise. Some of the Italian observers have attempted to divide these fevers, again, into (c) quotidian fever, and [d) malignant tertian fever. In this country, however, we see probably only the quotidian type. With each of these types of fever is associated a dis- tinct type of the specific micro-organism. (a) The Parasite of Tertian Fever. — Golgi was the first observer who accurately described and differentiated the organisms of the tertian and of the quartan forms of malarial fever, and his admirable observations have remained practically unassailed. If we examine the blood from a case of tertian fever just after the paroxysm, Ave find in certain of the I'ed blood-corpuscles small round, colorless bodies (Fig. 1, i- 2- s^ which appear to have a slight depres- sion in the centre, and when stained in dried specimens show a paler central area with a darker periphery. These bodies, examined in the fresh specimen, MALARIAL FEVER. 321 shaw active amoeboid movements. A few hours later the organism will be found to have increased somewhat in size, and to contain a few fine brownish pigment-granules which dance actively under the eye (Fig. 1, ^), the motion probably being due to undulatory movements in the protoplasm. On the day between the paroxysms the bodies will be found to have about half filled the red corpuscle (Fig. 1, ^). They are still actively amoeboid, and the number of pigment-granules has considerably increased. The red cor- puscle at this stage will be seen to be a trifle larger than its unaff"ected neighbors, and to be considerably decolorized. On the day of the paroxysm Fig. 1. ,'? S% /^ The Parasite of Tertian Intermittent Fever (drawings made from the blood of patients in the Johns Hop- kins Hospital, with the camera lucida.

The pigment-granules may show at this stage a very active motion, but the amoeboid movements of the organism as a whole are but little marked. At the time of the paroxysm an interesting change takes place ; the pigment gathers together in a more or less solid clump, usually in the centre of the organism, while the rest of the protoplasm looks somewhat granular and shows a suggestion of 21 322 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. lines radiating outward from the centre (Fig. 1, *). This appearance gradu- ally changes, the lines becoming more distinct (Fig. 1, 9), until finally we see the central clump of pigment surrounded by from fifteen to twenty small ovoid or round glistening segments, each one having a central more refractive spot, and resembling strongly the hyaline bodies which we see immediately following the chill (Fig. 1, '^^). This segmentation of the organism is always coincident with the paroxysm, and the presence in the blood of a segmenting body is a sure indication that the paroxysm is present, or is about to occur. Immedi- ately folloAving the paroxysm fresh h^'aline bodies appear in the red corpuscles. Though the invasion of the corpuscles by these fresh segments has never been actually observed, the evidence that this occurs is so strong that we can safely accept it as a fact. Besides these forms Ave see not infrequently small or large extra-cellular pigmented bodies ; that is, organisms resembling exactly those within the red blood-corpuscles, excepting that they are free in the blood-cur- rent (Fig. 1, 11' 12^. These may be seen at times to break up into several smaller bodies, while at other times they may show a long, tail-like, non-motile process, containing sometimes a few^ pigment-granules. They are probably organisms which have escaped from the red corpuscles, or full-grown bodies which have broken up ; they are considered to be degenerative forms. At times also we find the so-called flagellate bodies. Their development from the pigmented organism may indeed be observed, the pigment of the full-grown body becoming very actively motile, then collecting in the centre of the organism, while several long, thread-like flagella burst out of the body and move actively about among the surrounding corpuscles (Fig. 1, ^ 2). Some- times we may see one of these flagella which has broken away from the organ- ism and is moving rapidly through the field. This is also thought by the Italians to be a degenerative process. The characteristics of this form of organism, which is observed in tertian fever alone, are so marked that with a little study of the parasite one can make a definite diagnosis of the type of fever from an examination of the blood alone. (h) The Parasite of Quartan Fever. — Quartan fever is not at all common in this country, but in the few cases which the writer has observed the organisms differ distinctly from the tertian parasite, and show accurately the characteristics described by Golgi. Here the first stage of the organism is similar to that observed in tertian fever, excepting that the amoeboid move- FiG. 2.

As the body develops the rods and clumps of pig- ment are larger and darker than those in tertian fever, w^hile the amoeboid MALARIAL FEVER. 323 movement of the organism is relatively slight. The full-grown forms are materially smaller than in tertian fever, while the red blood-corpuscle, instead of being expanded and decolorized, appears at times shrunken about the body, and of a somewhat deeper old-brass color (Messingfarbe). In segmentation the organism divides into from six to ten different parts instead of tAventy or thirty, as in the tertian form (Fig. 2, i"'^), ((?) The Organisms of the j^stivo-autumnal Fevers. — The organisms asso- ciated with the ffistivo-autumnal fevers have been carefully studied, but much remains to be done, particularly in this country. There is some diiference of opinion as to whether there are not two types of organism associated with these fevers. Some Italian observers divide them into the quotidian and the malignant tertian organisms. The differences made out by the Italians are, however, very slight, and have not been observed in this country. In the first place, we see just after the paroxysm small hyaline bodies which may or may not be actively amoeboid; these can sometimes be distinguished. from those appearing in the initial stage of either tertian or quartan fever, in that they are generally somewhat smaller and have oftentimes a charac- teristic ring-like appearance (Fig. 3, i"*). In the early stages — during the first week, for instance — of an attack of this form of fever we may see only the hyaline, unpigmented forms, but commonly, if we observe carefully, we may see, some time after the exacerbation of temperature, shortly before the beginning of another, bodies which are a trifle larger than these smallest hyaline forms, and which contain one or two very minute pigment-granules lying near the periphery (Fig. 3, ^' *). Just before or during the paroxysm we may see Fig. 3. Parasites seen in ^I^sti vo-autumnal Fever— tropical malaria. (Drawn with the camera lucida from the blood of patients in the Johns Hopkins Hospital ; Winckel, 1-14 oil immersion lens, 4 eve-piece.) : 1, 2, 3, hya- line, ring-like amceboid bodies seen in the blood toward the end of the paroxysm ; 4, the same further developed ; -5, 6, disc- and ring-shaped bodies with one or two small pigment-granules, seen shortly before a paroxysm ; 7, full-grown body with central pigment-granules, seen during paroxysm : 8, full- grown body with central active pigment-corpuscle crumpled and shrunken : 9-12, crescentic and ovoid bodies with coarse central pigment. 9 and 11 show remains of the corpuscle (from a case of chronic malaria with normal temperature). bodies with a small central clump of motile or non-motile pigment-granules lying usually in cells which are more or less shrunken and crumpled, and of a deeper color than the normal corpuscles (Messingfarbe). These bodies are 324 A3IERICAN TEXT-BOOK OF DISEASES OF CHILDREN. generally not half as large as the red corpuscle (Fig. 3, ^'^). After the first week or ten days of the disease, or after treatment has been begun, we see, however, certain very characteristic and easily recognizable forms which are only seen with this type of fever. These are, first, round or ovoid bodies about the size of a red blood-corpuscle, a little smaller or a little larger, with clear, rather highly refractive, waxy-looking protoplasm, and coarse dark pig- ment-granules, which are usually collected in a ring or a mass in the centre of the organism (Fig. 3, 9- 1^- ^'^). The granules are usually very slightly motile. At one side of the body we often see a small bib-like attachment which may show a slightly yellowish color. On examination this proves to be the remains of the red blood-corpuscle in which the organism has developed. In association with these are seen crescentic bodies (Fig. 3, ^ i), the protoplasm of which shows the same characteristics as that in the forms above described, while the pigment is collected in the middle in a similar ring or bunch, and is but slightly motile. . On the concave side of these crescents one may also often see a bib-like attach- ment, just as in the ovoid forms. At times during the examination of the fresh specimen Ave may see the change from an ovoid body into a crescent take place. The development of these forms from the hyaline bodies can be followed out on careful observation. They are thought by some to be a resting stage of the organism. Segmenting bodies are almost never seen in the circulating blood of this form of malarial fever, though the presence of the round intra- cellular bodies with central pigment is a sure sign that segmentation is going on elsewhere. It has been found by the Italians that after the accumu- lation of a few pigment-granules the organisms seek the internal organs, where segmentation takes place. The bodies are still small and contained within the red corpuscle. The pigment gathers in the centre, as in the other types of segmentation, Avhile the segments are very small and rarely more than twelve in number. During the paroxysm we may see large numbers of leuco- cytes containing pigment granules and clumps which are probably the remains of segmenting organisms. Flagellate bodies may be observed here as in the tertian and quartan fevers, but only when ovoid and crescentic pigmented bodies are present. They may be seen to develop from the round bodies with central pigment. Careful studies concerning the morphological characteristics of the malarial parasite have shown that it belongs to the class of Protozoa, and is possessed of a nucleus containing one or more nucleoli. At the time of sporullation this nucleus divides — according to some directly, according to others by karyokinesis. Pathological Anatomy. — In the acutely fatal cases of malarial fever (pernicious malaria) certain fairly characteristic changes are found in the various organs. The hraiti may show few changes. At times, however, there may be a slight subpial oedema, with hyperemia of the cerebral substance and per- haps punctate haemorrhages. Melanosis may be entirely absent. Micro- scopically, however, the changes are most characteristic. The cerebral capil- laries are crowded with malarial parasites, which may be in all stages of development, though generally one of these phases is most marked. At times the organisms may not be so numerous, but free clumps of pigment may be found, and large endothelial cells and leucocytes containing pigment-clumps and red corpuscles. There is usually a marked granular and fatty degen- eration of the endothelium of the vessels, a change upon which the punc- tate haemorrhages may depend. These lesions are particularly marked in the comatose forms of pernicious malaria. In other forms the cerebral lesions may be much less marked. MALARIAL FEVER. 325 The spleen is always enlarged : the capsule is tense ; the parenchyma is cyanotic, of a slaty-gray color, and almost diffluent. In some cases of acute malaria death may occur from rupture of a greatly enlarged Spleen. The pulp contains enormous numbers of red blood-corpuscles, many of which contain parasites. It also contains numerous large white elements rich in protoplasm, containing usually a single bladder-like nucleus, and at times coarse granula- tions. These elements are usually laden with pigment, which at times has the same arrangement as it does in the body of the parasite itself. Sometimes these cells may contain the entire red corpuscle with the organism. There may be free pigment in the intercellular spaces of the pulp. The small mononuclear elements and the lymphocytes of the follicles never contain pig- ment. The capillaries are usually filled with the plasmodia, while the splenic veins show relatively few, though they always contain large cells enclosing pig- ment or the remains of red blood-corpuscles. The liver has usually a slaty-gray color. There is always cloudy swelling, while microscopically small areas of necrosis have been described by Guar- nieri. The capillaries ai'e filled with leucocytes which contain numerous pig- mented bodies. Relatively few plasmodia are found in the blood-corpuscles in the vessels. Numerous liver-cells are found containing clumps of hsematin and altered red corpuscles — a condition similar to that which has been found in pernicious angemia, which, as Bignami suggests, may explain the polycholia which is commonly found in subjects who have died of pernicious malaria. On this probably depends the icteroid hue in severe malaria. The lungs show in their capillaries numerous cells containing pigment-clumps and well-preserved parasites, though it is unusual to find pigment in the endo- thelial cells, in the capillaries; and smaller veins. In the areas of broncho- pneumonia which may occur, polynuclear leucocytes are chiefly found, while the large pigmented cells take no part apparently in the active inflammatory process. The vessels of the kidneys contain relatively few organisms. The glomeruli may be considerably pigmented. There may be marked degeneration of the epithelium of the capsules, and at times changes in the parenchyma, especially areas of necrosis of the epithelium of the convoluted tubules. The other viscera show no especially characteristic changes excepting at times the melanosis. In the more clironic forms of malaria and in malarial cachexia the anaemia is usually particularly marked. The spleen is always enlarged and very firm. There is a marked thickening of the capsule, which is often adher- ent to the neighboring tissue. On section the spleen is generally of a dark brownish-gray color, the fibrous tissue throughout the organ being greatly thickened. The liver is considerably enlarged, and usually has a grayish- brown or slaty color. Microscopically, Kupfer's cells and the perivascular tissue may contain much pigment. At times there is a considerable increase in the connective tissue. The kidneys show no particular characteristic changes, though there may be considerable pigmentation ; the pigment is most marked about the blood-vessels and the Malpighian bodies, and sometimes in the region of the convoluted tubules. There are no characteristic changes in the other organs, excepting the slaty-grayish pigmentation. Symptoms. — As may be gleaned from Avhat has already been said con- cerning the specific organisms, malarial fever occurs in sevei'al main types : (1) The milder intermittent fevers, which form the majority of all cases in the more temperate climates, and occur in the warmer climates more commonly in the spring and early summer : {a) Tertian intermittent fever and its combi- nations ; (5) Quartan intermittent fever and its combinations. (2) The more irregular, sestivo-autumnal fevers, which usually show quotidian paroxysms. 326 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Tertian Intermittent Fever. — This is by far the commonest form of malarial fever in this country, and with the quartan fever forms the mildest type of the disease. It is the type of the intermittent fever of the spring and early summer, though it may be seen at any time of year. It shows often no particular tendency to increase in severity, while in many instances, under proper care and change of climate, spontaneous recovery may oc- cur. It depends, as we have seen, upon the invasion of the blood by an organism which passes through its cycle of ex- istence in forty-eight hours. The febrile paroxysms occur when these parasites have reached their full development and begin segmentation. These periods occur with considerable regularity at intervals of forty- eight hours one from another. In older children the parox- ysms may usually be divided into three stages : first, the chill; secondly, the fever ; and thirdly, the sweating. The child, who may have been feel- ing fairly well beforehand, be- comes suddenly uneasy, may begin to yawn, or may have an attack of vomiting or diarrhoea, which is followed or accom- panied by a well-marked rigor, associated with cyanosis and coldness of the extremities. The temperature rises to a con- siderable height, possibly to 108° F. This stage lasts for a varying time, from ten min- utes to an hour. As the chill ceases the patient passes into a stage in which there is marked flushing of the skin, Avith great heat and dryness.

MALARIAL FEVER. 327 able length of time, from half an hour to three or four hours, is folio-wed by profuse sweating, the temperature falling within an hour or two to a normal or even a subnormal point. With the sweating the child may seem exhausted and weak, but shortly afterward appears again perfectly well. Such an attack as this differs but little from the intermittent fever of adults, and indeed above the age of six the differences are very slight. Under this age, however, there are marked differences in the paroxysm. Very com- monly in young children both the first and the third stages, those of the chill and sweating, are absent. The first stage is then generally represented by a slight restlessness, the face looks pinched, the eyes sunken, the finger-tips and toes may become cyanotic and cold, while the child may yawn or stretch itself. Oftentimes there is nausea or vomiting, and possibly diarrhoea. This may be the only manifestation of the first stage, though it may be followed by slight or severe nervous symptoms. These begin usually with a slight spasmodic twitching of the eyelids or of the extremities, and may go on to general convul- sions. The chill in the adult is very often represented in the young child by the convulsion — a fact which is as true in all other acute febrile processes as in malarial fever. This stage lasts usually for a short time, not more than an hour or so. The temperature rises rapidly, possibly to 108° F. ; then comes the period of fever, during which the child is much flushed, is restless, thirsty and fretful, while, as has been already said, various gastro-intestinal disturbances may occur. The fever remains at its height for an hour or two ; afterward there is a gradual fall of temperature, unaccompanied by sweating. In many instances, besides the slight coldness of the hands and blueness Fig. 5. •Venip ' 1 ts .07 si|i = ■■I'igi =iji=: -====; s o! * # ^ infi t ■^!-» «!-! ^»-oa)SS!veight of the head that it is uncomfortable and rest- less. It does not have quiet sleep because the cerebral circulation and functions are disturbed l)ecause of the fact that the cranial arch no longer protects the brain from undue pressure. Carefully placed in an apparently comfortable position, it awakens often and frets until it is taken in the nurses arms. Some- times it instinctively seeks a position on the edge of the pillow, with its face downward, and it becomes more quiet Avhen resting over the nurse's shoulder with no pressure or support upon the cranial arch. But if fretfulness, disturbed sleep, and the necessity of closer attention on the part of mother and nurse were the only ill effects of craniotabes, it would possess much less pathological significance than pertains to it. Pressure upon so delicate and important an organ as the brain involves risks and produces serious symptoms in proportion to its degree. Even a slight injury of the skull which causes depression, though it may be of trifling amount, will cause serious forms of nervous disorder. Rachitic craniotabes sustains a causal rela- tion in not a fcAv instances to one of the most dangerous of the neuroses — to wit, larjjnghmus stridulus, or spasm of the glottis. Pressure on the cardiac and vaso-motor centres of the medulla in the rachitic infant, in whom reflex excitability is exaggerated, causes contraction of the muscles that close the glottis. It is certain that a large proportion of those who suffer from laryn- gismus stridulus are rachitic, so that it is more common and severe where rachitis is prevalent, as in England, than where it is rare, as in the rural districts of America. It is not often the cause of death in America, and the fatal cases that do occur are, I think, nearly ahvays in the cities, whereas in parts of Europe, Avhere rachitis is much more common than with us, it is said to cause not a few^ deaths. Certain infants when in a state of excitement have what are termed "hold- ing-breath spells." The face is flushed and breathing ceases for some seconds, after which respiration returns and is normal. The attacks are unimportant, but they appear to be the same in nature with the more severe and dangerous seizures of laryngismus stridulus. They have no pathological significance, excepting that they show the same neuropathic state as that in laryngismus, and that they may be precursors of it. Laryngismus stridulus, or glottic spasm, is usually preceded by more or less impairment of the general health and often by fretfulness, which'is charac- teristic of the rachitic state ; but the attack occurs suddenly, without premonition, and is of short duration. It begins with an arrest of respiration, a true apnoea, as if from paralysis of the respiratory centre in the medulla ; the lips may be livid, a pallor spreads over the face; sometimes more or less rigidity of the limbs occurs, with carpo-pedal contractions. After a few seconds, a quarter or half minute, a long and deep but difficult inspiration through the narrow chink of the glottis follows, accompanied in many patients by a whistling or crowing sound, and the attack ends with perhaps a momentary appearance of bewilderment or dread on the child's lace. Laryngismus stridulus, like eclamp- sia, does not have a uniform causation. In certain cases it is a reflex phe- RACHITIS. 357 nomenon due to an irritant in some part of the system, as in the intestines, but many, observations establish the fact that rachitis is probabl}^ its most common cause. A large proportion of the infants affected with it exhibit unmistakable rachitic signs ; and it has been held that the exposed state of the brain in craniotabes affords explai^ation of the symptom. But from obser- vations which I have made and from those of other observers, like Senator, it is certain that larvng-ismus stridulus is common in the rachitic who do not have craniotabes, so that there must be a causal relation in rachitis to spasm of the glottis independently of the cranial softening. Distinguished British observers, as Gee and Jenner, have noticed the fact that rachitic infants are especially liable to eclampsia. The immediate or exciting cause seems to be in many cases the severe catarrh of the respiratory and digestive systems to which rachitic infants are especially liable. Indiges- tion, flatulence, and fermentative diarrhoea, common disorders of the rachitic, are perhaps, in some instances, the exciting causes of the eclampsia. Similar remarks may be made in reference to tetany, which, although it occurs in the adult and is comparatively rare, appears to be more frequent in rachitic than in other children. Those physicians who attend in institutions in which children coming from tenement-houses are treated in a large city like New York have noticed the fact that the various tissues of the body, besides those that are conspicuously affected in rachitis, are more liable to inflammatory diseases than are the same tissues in those who have sound constitutions. The frequency of the different forms of dermatitis, of nasal, post-nasal, faucial, and bronchial catarrhs, and of gastro-intestinal maladies, we must attribute to the fact that rachitis dimin- ishes the resisting power to noxious agents in the various soft tissues, and ren- ders them more liable to disease. If the deformity in the thoracic wall — to wit, the lateral depression of the ribs and anterior projection of the sternum — be great, we would naturally expect that the two important organs underneath, the heart and lungs, would receive some detriment. Upon the surface of the heart, at the point where it supports the softened ribs, a white patch is often found, due to thickening of the pericardium and proliferation of the endothelial cells, just as thickening of the skin in the palm of the hand occurs from friction and pressure upon that part. It is probable that in ordinary cases this pressure does not seriously impair the function of the heart, but it may inci^ease the weakness of its move- ments in supervening asthenic diseases, which may occur during the rachitic period. The injury sustained by the lungs is greater and more apparent. If the lateral depression of the ribs be considerable, full inflation of the lungs does not occur in those parts where the depression is greatest. The semi- collapse of certain lobules is likely to occur, and even complete collapse of the distant thin edges of the lungs. The stress of respiration falls unequally upon different parts of the lung. The anterior portion, which ascends with the sternum as that is propelled forward, is more fully dilated than the lateral and posterior parts, and it may in consequence become emphysematous. If in this state of the thorax and lungs severe bronchitis or broncho-pneumonia occurs, the muco-pus, being expectorated with difiiculty, clogs the tubes, produces dyspnoea, and imperils the safety of the child. Even in comparatively mild forms of inflammation the result may be unfavorable, owing to the lack of full expansion in the lateral and depending portions of the lung — a condition required to expel the mucus. Severe bronchitis and broncho-pneumonia are the causes of death in not a few cases of rickets attended by marked deformity of the thorax. a58 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Rachitic Paralysis. — In not a few instances in the course of rachitis the use of the limbs is greatly impaired, so as to resemble paralysis, and be desig- nated by this name, thoiagh the term "paralysis" is probably a misnomer. Cases like the following, related by Dr. H. W. Berg in the New York Medical Record, which closely resemble paralysis, occasionally occur: J. S , aged two years and eight months, was admitted into the Orthopaedic Dispensary Sept. 23, 1885. The parents stated that the child had never Avalked or stood alone. The legs were Avasted, apparently from disease ; the patellar reflex was good; there seemed to be some rigidity of the muscles about the knee; and the patient was admitted with the diagnosis of ''spastic paralysis." A closer examination disclosed the fact that the disease was one of typical rachitis, and by the use of the proper diet, with iron and phosphorus, the patient was able to walk in November, and in a few months was entirely cured. The British Medical Journal, Jan. 4, 1890, contains the account of a case of rickets dis- cussed by the Edinburgh Medical Society, Dec. 4, 1889. The patient, a boy of three years, had the waddling gait and straddling pose of pseudo- hypertro- phic paralysis. The rachitic nature of the malady was made apparent by the symptoms of the case and its history. I have recently in private practice observed two similar cases of pseudo-paralysis of the lower extremities from the same cause. Acute Rickets. — Occasionally rachitis occurs with the sudden develop- ment of severe symptoms, so that the term "acute ' is applied to it. Dr. Flirst relates such a case in the Jahrh. fiir Kinderh., Band xviii. p. 192 : The patient, aged two years and one month, had been largely fed upon starchy food, and at six months had dyspeptic symptoms and sweating. Dentition began in the thirteenth month, and ability to walk several months later. Spas- modic croup and swelling of the epiphyses appeared at this time. At the above-mentioned age the child suddenly fell ill with acute febrile symptoms. It had an open anterior fontanelle, craniotabes, and a rachitic chest; upper extremities free from pain and not swollen. The left femur and both tibiae showed diffuse cylindrical swelling. The appearance and feel of the limbs were suggestive of diffuse cellular infiltration proceeding from the periosteum in an attack of osteo-myelitis. The skin covering the limb was tightly drawn and of a reddish hue. In a few days the right forearm was affected, and soon after the right arm and left forearm, and the parts first attacked began to improve. In four weeks the fever and pain had abated, but swelling of the epiphyses and deformities of various bones continued. Cases like the above establish the fact that although rachitis is ordinarily a chronic disease, insidi- ous in its commencement, gradual and progressive in its development, occupy- ing months, there is an acute form which is attended by more marked febrile movement and tenderness than occurs in the usual type, and in which the articular swelling appears more quickly. Treatment. — Hygiene. — We recall the recent statement of Prof. Henoch of Berlin that the spread of rachitis has been enormous in the cities of Central and Northern Europe. The poor of these cities, among whom this disease largely prevails, are emigrating in large numbers to the United States, but, as I have observed in the asylums and dispensaries of New York, the severest forms of imported rachitis come from Southern Europe (Italy). Evidently, as long as the influx of this class of foreigners continues, and the present insani- tary conditions exist in our cities causing rachitis in the native born, this will continue an important disease, impairing the health and vigor of coming generations. It is evident from the nature of rachitis that success in prevent- ing it and in curing those who unfortunately exhibit its characteristic signs RACHITIS. 359 requires beyond anything else the employment of proper hygienic measures. The details of the hygienic requirements may seem prolix and tedious, but we cannot expect any marked diminution of rachitis until they are better known and heeded by the masses. The fact that inheritance is one of the recognized causes of rickets renders it very important that the parents be in good health. The mother especially should avoid all agencies or influences which impair the general health during the procreative period. She should, so far as possible, encourage good appetite, take plain, easily-digested, and nutritious food, and lead a quiet, regular life, with sufficient out-door exercise to promote, so far as practicable, a state of perfect health. Country residence, with quiet exercise in the open air, a diet consisting of fresh vegetables, meats, fresh and abundant milk, early retirement to bed and sufficient sleep, are much more conducive to the health of the mother and her child than are the excitement and irregularities of city life. We have seen that there is sufficient clinical and experimental evidence that the common and predominating factor in causing rachitis is the use of a faulty diet, but general insanitary conditions are also potent agents. The foul air and noxious effluvia of the crowded tenement-house, so conducive to disease and fatal to infants in New York, should, if possible, be avoided. Even if poverty compels a residence in the small and dark apartments of a tenement-house, crowded by families, many of them entirely neglectful of sanitary measures, yet parents solicitous for the welfare of their children can do much to diminish the insani- tary influences which surroimd them. Out-door air is everywhere available, and every child after the age of two or three months, unless suffering from acute disease, should in ordinary weather be in the open air one or more hours each day, as a means of improving its digestion and of producing a more vigorous state of the system. Any mother or nurse capable of the care of a child should be able to employ such measures as Avill prevent its taking cold while in the open air. The room occupied by a child, whether rachitic or not, should be at a uni- form temperature of about 70° to 73° F., and it should receive the sunlight or the full daylight, which is often excluded by faulty construction. The under- garments worn during infancy and childhood should be of wool, thin and light during the summer, thicker and heavier in the winter. No intelligent mother need be told of the need of personal cleanliness of her child as a means of promoting its health as well as comfort. This is a hygienic measure, and we need not repeat that the more complete the sanitary conditions the less the lia- bility to contract rachitis or any disease dependent on cachexia. Bathing of children should always be before the fire or in a warm room. The bath for an infant under the age of six months should be at about 90°. As the age increases the temperature of the bath should be gradually reduced to 80° in the second year, to 75° in the third year, and to 70° subsequently. The bath should be short, only long enough to ensure cleanliness. For weakly infants it is sometimes best to dispense with the general bath, and employ the sponge instead. I see no advantage in the use of saline or medicated baths. After the bath the extremities should be warm, and to ensure a better peripheral cir- culation friction of the surface by warm flannel or otherwise, or the application of warmth to the limbs, is often useful. The extremities of a child should always be warm, for the normal warmth of the surface not only promotes nutri- tion of superficial parts, but it tends to prevent internal congestions and inflam- mations, to which the rachitic are especially liable. A child that habitually has cool extremities cannot be at the maximum of health, and this is often the state of the poorly-fed and poorly-clad children of the tenement-houses. The 3G0 AMERICAX TEXT-BOOK OF DISEASED OF CHILDREN. measures to promote their normal circulation and warmth, such as exercise as far as practicable, artificial heat, exclusion of cold by woollen garments, friction of the limbs, either dry or by the use of mildly stimulating lotions, should be employed. But while the hygienic measures which we have detailed are important as means of invigorating the system and rendering it less liable to rachitis as well as other cachectic diseases, we repeat that the most common and potent cause of the malady which we are considering is a faulty diet, so that in the endeavor to prevent and to cure rachitis special attention must be given to the feeding. Clinical experience abundantly demonstrates the fact that in order to pro- mote healthy nutrition the food of the infant should be breast-milk until the age of ten or twelve months ; and subsequently, until childhood is well advanced, its food should consist largely of cow's milk, properly preserved and prepared. We need not state that human milk varies in its composition according to the health, diet, mode of life, and temperament of the individual who furnishes it. Many mothers possess the requisite moral traits to be good wet-nurses, and do all in their power for the welfare of their infants, but have an inadequate lacteal secretion. Many mothers, not only in the tenement-houses, but in the well-to- do class, are unable to furnish sufficient breast-milk, and their infants, unless they receive supplementary food, suffer from malnutrition and are liable to become rachitic. I have seen during the last year infants wet-nursed by their mothers, fretful, wasted, and at the verge of starvation, applied every half hour to the breast during the hours of wakefulness. Mothers, deprived of the needed sleep and sacrificing their own health in the constant endeavor to pro- vide for the wants of their infants, usually have insufficient milk, as in the cases alluded to. Under such circumstances a medicine designated nutrolactis, which consists largely of the Galega officinalis, has been employed in the New York Infant Asylum with apparent benefit as a stimulator of the lacteal secretion. But if suckling by the mother continue inadequate and her infant be under the age of six months, a wet-nurse should be employed. If this be impossible, supplementary feeding will be needed. In normal and sufficient wet-nursing the infant should go to the breast at regular intervals of about two hours, but at longer intervals at night (ten times in tAventy-four hours). It should obtain what nutriment it requires in ten or fifteen minutes, after which it falls into a quiet sleep. This allows the mother time and opportunity to rest and recuperate between the nursings, so that she furnishes milk more abundant and of better quality than when she is worried and anxious and deprived of needed sleep. The subject is so important that we may be allowed to repeat what we have elsewhere stated : An infant that draws the breast at short intervals of two hours obtains not only more milk, but richer milk, than when the intervals are longer. There is no more important, and frequently no more perplexing, duty of the physician than to direct the alimentation of infants. Many mothers express the determination to wean for trivial reasons, and are found to be giving one of the commercial foods without consulting the physician. On the other hand, many motliers seriously declare that their babies are ravenous nursers, and that their breasts furnish an abundance of milk, Avhen only a few thin drops can be obtained by the breast-pump, and the appearance of the nurslings plainly indicates innutrition and progressive emaciation. In such cases addi- tional nutriment is of course required. The practice, which is too common, of early weaning Avith insufficient reason and without consulting the physician, is very mischievous. Acute and transient ailments of the mother may cause some diminution in her milk, but RACHITIS. 361 usually her health is not so injured by a short sickness that she is incapaci- tated for wet-nursing ; of course the continued loss of appetite, with progressive debility and anaemia, may be such that prompt weaning is imperatively required. If it be impossible to wet-nurse the infant, or if it have reached the age of ten or twelve months, at which time weaning is proper, it Avill be necessary to determine what food shall be given. In New York City — and the same is prob- ably true in other cities — the infant should not be weaned in the hot months, since the change of diet from the natural to the artificial at this time is very likely to cause that fatal disease, the summer diarrhoea. The infant should be first removed to the country before weaning, or, if removal be impossible, wean- ing should be postponed until after the heated term, even if it be at the age of fifteen or sixteen months. But with a large proportion of infants after the age of six months the mother's milk is not sufficient, and it is necessary to supple- ment the wet-nursing by the use of other foods. Notwithstanding the many commercial foods designed for infant feeding, I have every year been more and more convinced that cow's milk, prop- erly prepared, furnishes the best substitute for human milk, and should be used to make up the deficiency when the latter is insufficient, and be the main food or the basis of the food employed after weaning. I have observed the occurrence of rachitis in children Avhose diet consisted chiefly of certain proprietary foods ; and, in looking over the composition of these foods, one of the chief causes of this result appears to be the small amount of fat which they contain. Thus, according to Prof. Leeds's analyses, Mellin's Food contains only 0.15 part in 144.74, and Nestle's Food only 1.91 parts in 139.69, whereas human milk contains 3.90 per cent, of fat, and cow's milk 3.66 per cent, of fat. Especially in the selection of food designed to prevent or cure rachitis our choice should fall on cow's milk next to human milk. But cow's milk contains five times more casein than human milk, and is slightly acid, whereas the latter is always alkaline. In the counti-y, cow's milk obtained fresh and with proper attention to cleanliness in its manipulation may not require sterilization by heat. But that received and used in the city, exposed more or less to an atmosphere containing numerous microbes, it is well to sterilize by steaming for a period not exceeding twenty-five minutes. For infants with feeble digestion, who are suffering from innutrition, digestion of cow's milk can be pi"omoted by pepton- izing by the peptogenic powder of Fairchild in the manner well known to the profession. Inasmuch as observations relating to the causation of rachitis, which we have quoted elsewhere, show that deficiency of fat in the food is a common cause, I recommend, especially if any rachitic symptoms appear, the use of the upper half or third of the can or bottle of milk, since this contains a large percentage of cream. A properly-prepared farinaceous substance, mixed with milk, not only has nutritive properties, but also, by mechanically separating the particles of casein, tends to prevent the formation of curds in the stomach. But as young infants digest starch with difficulty, a flour, as barley, wheat, or oatmeal, in which the starch is to a great extent converted into dextrin, or, better, into glucose, may be advantageously added to the milk, especially for infants over the age of six months. The conversion of starch into dextrin may be effected by a high heat, and into glucose by the action of diastase. If a heaped teaspoonful of barley flour be boiled in twenty-five teaspoonfuls of water, and when it is lukewarm ten or fifteen drops of diastase (Forbes) be added to it, the gruel in a few min- utes becomes much thinner from the digestion of starch, and it is a useful adju- vant to the milk employed in the nursery, especially for infants over the age of six months. 362 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. But while healthy development in infancy and childhood requires a careful choice of food suitable for the stage of growth and development, the frequency of the feeding and the amount of food given are also matters of importance. There can be no doubt that many infants are under-fed, some even to starva- tion, and some infants are over-fed. MM. Vernois and Becquerel, in a careful examination of 89 infants wet-nursed by mothers apparently in good health, ascertained that 15 were insufficiently nourished. Did space permit I might relate instances in which infants were applied to the breast even more fre- quently than the prescribed rules allow by aflFectionate and devoted mothers or by wet-nurses supposed to have sufficient milk, and yet they continued to lose flesh and strength, were almost constantly fretful, and Avere finally reduced to a precarious state by insufficient nutriment. On the other hand, overfeeding sometimes occurs to the detriment of the child. A half century has elapsed since the most distinguished New England physician of his day, Dr. James Jackson, called the attention of the profession to the frequent, green, and unhealthy stools, showing imperfect digestion occurring in children from over- feeding. Among the cachexise developed from abnormal digestion and malnu- trition we recognize rachitis as one of the most frequent. A few years ago Drs. Chadbourne, Parker, and myself made observations in the New York Infant Asylum and New York Foundling Asylum in order to determine how much food children require at different ages. Those selected for observation Avere well nourished, and they were accurately weighed before and after each nursing or feeding. Eleven infants under the age of three weeks, who took the breast, with three exceptions, twelve times in the twenty- four hours, Avere found to take on the average 12.55 ounces of the breast-milk in the day and night. Therefore, according to these statistics, infants under the age of three Aveeks, nourished at the breast and suckled twelve times in the tAventy-four hours, require only one ounce, or not more than one ounce and one drachm, at each nursing; and the very small size of the stomach at this age shows that it cannot receive much more than this without distention. After the third Aveek the amount of food required for healthy nutrition gradually increases. Children, like adults, in good health and well nourished, do not all require or take the same amount of food. Some need more food than others, but the folloAving table indicates, I think, nearly the quantity required during the first twelve months of infancy, either of breast-milk or of food prepared so as to resemble as closely as possible breast-milk in consistence and nutritive proper- ties. It will be observed that this table resembles closely that prepared by Prof Rotch of the Harvard Medical School, and published in his instructive paper on infant feeding in the Cyclopcedia of the Diseases of Children: Quantity of Food required in the First Year of Infancy. At each Feeding. Number of Daily Feedings. Total Daily Amount. During the first week 1 oz. 10 10 oz. At the third week 1^ oz. 10 15 oz. At the sixth " 2 oz. 8 16 oz. At the third month 3 oz. 8 24 oz. At the fourth " 4 oz. 7 28 oz. At the sixth " 6 oz. 6 36 oz. At the tenth to twelfth month . . . 8 oz. 5 40 oz. The daily average of food for each child in an aggregate of twenty-eight healthy children between the ages of tAvo and three years was as follows: Bread, 7.5 oz. avoir. ; butter, .98 oz. ; meat (beef), 4.6 oz. ; potatoes, 3.9 oz. ; milk, 32.6 fl. oz. The daily average for each child in an aggregate of twelve children between the BACSITIS. 363 ages of three and six years was as follows: Milk, 48.6 fl. oz. ; beef, 12.1 oz. avoir.; rice, 18.0 oz. ; bread, 10.3 oz. ; butter, 1.08 oz. The daily average for each child in an aggregate of twenty-four children between the ages of four and ten years: Roast beef, 12.46 oz.; bread, 10.23 oz. ; potatoes, 10.03 oz. ; butter, .99 oz.; milk, 38.5 fl. oz. The prevention and the cure of rachitis require strict enforcement of the details of hygiene. Hence the above facts relating to the mode of life and diet of children should be observed in order to prevent cachexia and promote a healthy growth. Medicinal Treatment. — Medicines Avhich aid the digestion and assimila- tion of properly-selected foods are sometimes useful. Irritability of the stomach, imperfectly digested stools, flatulence, colicky pains, etc. indicate faulty diges- tion, which may be improved by pepsin given with each feeding. Tonic reme- dies designed to improve the appetite and digestion, of a kind suitable for the age and condition of the patient, are often useful. In anaemia one of the readily-assimilated preparations of iron should be given. The complications which are so common require special management. The laryngismus stridulus, eclampsia, and tetany should be promptly treated. The bronchial catarrh to which rachitic infants are liable may be best treated by remedies like the following: ^. Ammonii chloridi 3J. Syr. Tolutan fsij.— M. Sig. Dose fifteen drops every hour or two hours for an infant of six to ten months. ^. Ammonii chloridi Ferri et ammonii citratis da 3ss. Syrupi ■ • f5j. Aquae fsiij- — ^I- Sig. Give one teaspoonful every two to four hours to a child of one year. Some of the rachitic cases with protracted bronchial catarrh, especially those which also exhibit scrofulous symptoms, may be most relieved by the syrup of the iodide of iron and cod-liver oil administered three times daily, with the inhalation of moist air containing turpentine vapor. In the protracted intestinal catarrh of rachitic infants I have observed the best results, so far as medicine is concerned, from the following prescription: ^. Subnitrate of bismuth 3ij— iij. Essence of pepsin (Fairchild's) f§j. Distilled water f^iij- — M. Sig. Shake bottle; give half to one teaspoonful, according to the age, every two hours. But a remedy is needed which will act promptly in the cure of rachitis so as to prevent the evil consequences which its continuance is sure to produce. It is the opinion of many of the best clinical observers who have had ample experience that this has been discovered in the daily use of minute doses of phosphorus. Wegner fed young and growing animals (rabbits and fowls) for months with small, non-poisonous, and easily assimilated doses of phosphorus, with the result, he believes, of expediting ossification and producing firmer bone. 364 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. He states that under the influence of pliosphorus the large marrow spaces diminish, by the formation of true bone, to the size of the Haversian canals in normal bone. According to Wegner, the administration of finely-divided, non-poisonous doses of phosphorus for a prolonged period to older fowls pro- duced to a considerable extent the conversion of cancellous into compact bone of normal chemical composition. Kassowitz has recently promulgated his views at some length on the pathology and treatment of rachitis. He states that the lime salts are not needed, since the ordinary food contains suf- cient lime ; nor should the ftirinaceous foods be restricted. He adds that phosphorus in small doses restricts the formation of vessels in the growing bones of small animals. Hence it is useful as a means of overcoming the hypenemia. Kassowitz administers about yts ^^ ^ grain in a teaspoonful of cod-liver oil, the dose, of course, varying according to the age of the infant. The distinguished pjediatrist of Vienna, Dr. Widerhofer, says of this remedy that its employment " impresses him with the belief that it is not without benefit in the second year of life and upward," He thinks that it may be useful in the hardening of long bones, but he has not been able to obtain good results in craniotabes. Starker gives an analysis of 23 rachitic cases treated by Prof. Thomas of Freibei'g in his clinic. He used the following formula : ^. Phosphori 1 centigramme (about \ grain). 01. morrhuse 100 grammes (about 3 ounces). — M. A coifee-spoonful was administered twice daily, but variations in the dose accord- ing to the age are not stated in the report, the patients being between the ages of a few months and four years. Improvement occurred in the general condition in 18 cases ; in the cranial development in 15 cases ; in dentition in 14 cases ; in the shapes of the epiphyses in 21 cases ; in locomotion in 17 cases ; but strict attention was bestowed upon the hygiene, and especially upon the diet. Soltmann states that good results occurred from the use of phos- phorus in 70 cases which he had under observation, and in no instance Avere unfavorable results noticed. W. Meyer obtained similar results in 42 cases. He regards phosphorus as a specific for rachitis. When properly given it always, says he, produces positive results. Petersen has treated 200 cases with phos- phorus, and regards it as a specific. Sigel concludes, from the observation of 40 cases in private practice, that constitutional treatment is of the greatest importance, but instead of the administration of iron, lime, etc., phosphorus should be prescribed. Unruh also made many observations in the treatment of rachitic cases by phosphorus in the Dresden Hospital in 1885 and 1886, and considers it more efficacious than other remedies. Toplitz of Breslau treated 518 cases with phosphorus combined with cod- liver oil. No ill effects were observed, and in all the cases improvement occurred in the general condition. Of 208 cases of craniotabes, 176 were cured in eight weeks. In 58 cases of laryngismus stridulus the attacks ceased in eight to fourteen days, after having continued for months under other forms of treatment. Dentition was also promoted. In America, Dr. A. Jacobi, who has had a large clinical experience, also highly recommends phosphorus in the treatment of rachitis. The dose should be small, even minute, not more than 2^^ ^^ y^ of a grain, according to the age, three times daih'. As regards my own observations, I am not able to express a positive opinion as to the value of the phosphorus treatment, for reasons which I think also apply to many of the cases embraced in the favorable statistics of the dis- RACHITIS. 365 tinguished observers mentioned above — to wit, tlie simultaneous use of cod- liver oil and improvement in the diet and general hygiene. The following pi-escriptions may be employed — first, the oleum phospho- ratum, made according to the following formula : !^. Phosphorus ' 1 part. Ether 9 parts. Almond oil 90 " — M. One minim contains yto ^^ ^ grain of phosphorus. Or, secondly, the following, known as Thompson's mixture : I^. Phosphori g^-j- Alcoholis (absolut.) TIX cccl. Spts. month, piperit TTLx. Glycerini .... . , fsij. — M. Sig. Six drops, increased to 10, three times daily, to a child of two to four years. Ten minims contain -^^^ of a grain, and thirteen minims contain -^-^ of a grain. Phosphorus should, I think, be given after the meals, in order to prevent irritation of the stomach. Dr. H, H. Purdy, physician to the large class of children's diseases in the out-door Department at Bellevue, has preserved statistics of the treatment of rachitis during the last year. The cases which furnish the statistics numbered about 80, and he gives a resum^ of the results of treatment as follows : " Some were given cod-liver oil alone, some, cod-liver oil with phosphorus, and others, phosphorus alone, and of course all the mothers were given instruction in feed- ing and hygiene. Those infants that received only phosphorus were the slow- est to improve. Indeed, in several cases this method of treatment was aban- doned because of the absence of the signs of improvement. The group treated with cod-liver oil did the best. In fact, all of the infants that could tolerate the oil derived much benefit from it. The group that were given cod-liver oil with phosphorus did very well, but seemingly no better than those that were given only cod-liver oil. The preparation that seems to be the most beneficial is one that is used at the Church Hospital and Dispensary. It is an emulsion of cod-liver oil made with the yolk of eggs. The formula for the emulsion is : ^. Yolks of ten eggs. Cod-liver oil Oij. Syrup of wild cherry Oj. Sherry wine Oj. — M. Sig. One or more teaspoonfuls administered three or more times daily." In my opinion the treatment by phosphorus is still tentative, notwithstand- ing its recommendation by so many distinguished physicians ; and the old remedies, cod-liver oil and iron, should not be abandoned, although trial may be made of phosphorus at the same time. Care should be taken to prevent deformities while the bones are soft and yielding. The patient should not be encouraged to stand or use the limbs until they become firmer. He should lie upon a soft and even mattress. Uniform support of body and limbs is requisite in order to prevent curvature. In craniotabes the pillows should be soft, and care should be taken that the yield- 366 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. ing parts of the cranium be not unduly pressed upon. Profuse perspiration may be relieved by sponging with vinegar and water. The patient may be bathed in water a little cooler than the body, and rock salt may be added to the bath. The attacks of laryngismus stridulus, eclampsia, and tetany which so fre- quently complicate rachitis should be promptly treated by the remedies which are appropriate when they occur under other circumstances. Constipation may be treated by enemata of glycerin and water if not relieved by change of diet. The surgical treatment of rachitic deformities is sometimes important, but Prof. Ogston of the University of Aberdeen and other surgeons who have given special attention to this subject state that in young patients these deformities frequently diminish during growth, so as to cause little inconvenience in adult life. The measures employed by surgeons in order to cure or minimize the deformities are fully set forth in surgical treatises. RHEUMATISM. By J. M. DaCOSTA, M. D., LL.D. Philadelphia. I. Acute Rheumatism. Acute rheumatism, or rheumatic fever, is a specific febrile malady characterized by inflammation of fibrous tissues, particularly those surrounding the joints, of Avhich many are apt to become afi"ected simultaneously or in suc- cession. There is also in rheumatism a strong tendency for the serous mem- branes, especially those of the heart, to become involved, and in children we frequently find these bearing the brunt of the disease Avhile the articular affection is very slight. Etiology. — The cause of rheumatism is the accumulation of some poison- ous matter in the blood which irritates specially the fibrous and serous tissues. The most commonly held opinion is that this poison is lactic acid, though the evidence is far from conclusive. The lactic acid may be the result merely of the morbid process, not the cause. Though sought for, specific micrococci have not been demonstrated, nor has the origin of acute rheumatism in disorder of the nervous system been proved. But, whatever the remote cause, it is certain that chilling of the surface is in the majority of instances the immediate cause producing the attack. A history of exposure to cold and damp can be almost always obtained. In instances, on the whole infrequent, the poison of scarlet fever produces pain, swelling of the joints, and even cardiac symptoms indistinguishable from acute rheumatism. The most potent predisposing cause of acute rheumatism in the young is hereditary tendency. Out of 492 cases Cheadle found a distinct history of its occurrence in near blood relations in 173. The strong hereditary tend- ency is also illustrated by the experience of Steiner : of 12 children of a mother who had suffered from acute rheumatism and heart complication, 11 had the disease before they were twenty years of age. Besides the complaint running in rheumatic families, I have noticed that the children of gouty parents develop rheumatism in greater proportion than found in those free from gouty taint. With reference to sex, unlike what happens in adult life, acute rheumatism is more common in girls than in boys. It is not often seen before six years of age. Yet August Seibert met with rheumatism in 13 children under one year of age, and cases of its occurrence in very young infants are recorded by Henoch, Senator, and Koplik. A case of acute rheumatism in an infant eleven days old is reported by Guthrie, and two remarkable instances of its manifesting itself soon after birth are mentioned by Jaccoud : one showed itself three days, and another twelve hours after birth, the mothers at the time being ill Avith acute rheumatism. I have myself met with a case of acute rheumatism under two years of age. This happened in a girl the daughter of a 367 368 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. highly gouty father. She has now grown to Avomanhood, having had three severe attacks of rheumatic fever, but without the heart becoming aflfected. Morbid Anatomy. — The joints show an injected synovial membrane, and there is effusion of fluid into them and into the surrounding tissues ; the fluid contains blood-cells and sometimes leucocytes. Minute hi^morrhages into the membrane are not uncommon ; the cartilages are swollen, but it is very rare for them to suppurate or to ulcerate. Near the affected joints and tendons fibrous nodules similar to those found on the valves of the heart are met with, and the parts around the joints, as Henoch has called attention to, may be infiltrated with inflammatory exudation that even becomes as hard as bone. Nodules growing from the bone, a nodular periostitis, have been described by Angel Money. In the heart inflammatory lesions are usual, both in endocardium and in pericardium. The pericarditis in the acute rheumatism of childhood, Cheadle' has pointed out, frequently extends to the anterior mediastinum, the connective tissue of which becomes extensively tliickened. The extent of pericardial effusion is not generally great, but there is much plastic exudation in the membrane. Fibrinous coagula are found in the heart and great vessels. Pleurisy with or without effusion is often seen. Symptoms. — The symptoms of acute rheumatism in childhood are the same as those of adult life : redness and swelling of the larger joints, pain, fever, per- spiration, heart involvement. But these symptoms do not occur in the same degree. The joint affection is apt to be slight — certainly the swelling and red- ness are — while stiffness and tenderness may be marked. The joints become successively involved, but in children it is not uncommon to find the rheu- matic inflammation limited to a very few joints, such as the ankles or the wrists. Even there it may be pain and tenderness rather than swelling that arrests attention. It is on account of the slight joint affection that acute rheu- matism in children is often overlooked, and the pain and tenderness are attri- buted to a fall or a sprain until the damaged heart tells the story. The fever is not high or long-continued; it is seldom above 102° F. Of those terrible cases with high temperature — temperature reaching from 107° to 110° — of which I have met with many in adults, I have never seen an instance in childhood. Fagge observed in 14 cases of the dreaded complication not one less than eighteen -years of age ; Wilson Fox, in 22 cases none less than seven- teen years ; Barlow records a fatal case in a girl of thirteen. Hyperpyrexia is certainly most unusual ; and so are the cases with delirium and other signs of cerebral disorder, and the cases with typhoid symptoms, whether associated with high temperature or not. Where the febrile rise is high and protracted there is apt to be delirium, and the morbid signs generally depend upon a heart affection, especially pericarditis. The tongue is not so coated as it is in adults ; the urine is high-colored, dense, with an excess of lithates. From among the usual symptoms of rheumatic fever we miss in children the profuse acid sweats. The skin is moist, but not bathed in perspiration. The heart symptoms of the rheumatic fever of childhood occur very com- monly ; indeed, in children endocarditis and pericarditis are more usual attendants on acute rheumatism than in adults. Endocarditis shows itself by increased restlessness, hurried breathing, dry cough, uneasiness or pain in the cardiac region, a rise in temperature or at least a sustained fever tempera- ture, and the development of a murmur, which is generally at or near the apex and systolic. This mitral murmur is followed by an accentuated second sound, or its reduplication, at the apex ; in rarer instances in place of a mitral an aortic murmur is present : in yet rarer instances there is a diastolic aortic murmur, or a diastolic or a presystolic mitral murmur. The impulse is some- RHEUMATISM. 369 what increased in force, slightly in extent, but the percussion dulness, diffi- cult to ascertain in a child, is not distinctly altered. The pulse becomes more tense, and its beats are not equal. As the case advances, impaired pul- monary resonance and fine rales indicative of congestion may be noticed, and restlessness and anxiety and irregularity of the circulation augment. Where ulcerative endocarditis takes place, recurring chills like those of malarial fever, followed by high temperature and profuse sweats, are apt to occur. And both in this form and in the simple form of endocarditis masses of fibrin may be washed from the vegetations into the vessels of the brain or elsewhere, and cerebral embolism or embolic pneumonia or other kinds of embolism thus happen. Besides the marked forms of endocarditis we may encounter only dulness of the first sound, giving it a murmurisli character, without decided general symptoms attending the ill-developed cardiac changes. These are instances of mere swelling and slight inflammation, and rarely result in persistent alteration of the valves, as the cases with well-defined murmur commonly do. Then, again, it must be borne in mind that there are many cases in which the general symptoms are so slight that the endocarditis readily escapes detection. Indeed, it is alone the recognition of the changes in the heart-sounds that makes sure of the presence of the malady. Pericay^ditis, owing to the greater difficulty of its recognition, is more often overlooked than endocarditis. This is especially the case in very young chil- dren, in whom, however, it is not common. It may occur at any stage of rheu- matism: sometimes it precedes the joint aifection ; often it pursues a sub- acute, irregular course, subsiding and breaking out anew as fresh joints become involved. The symptoms are those of endocarditis, but there are greater restlessness and distress, more marked signs of nervous disorder, a tendency to higher temperature, more cardiac pain. The physical signs are the same as in the adult ; prominent among them is the friction-sound, fol- lowed, when effusion takes place, by increased percussion dulness, by dispro- portionate distinctness of the sounds at the base as compared with those of the apex, by muffled sounds at the apex, and its upward displacement. It is much more difficult in children than in adults to make out the dulness, or to deter- mine its triangular shape or its existence in the fifth interspace to the right of the sternum ; and very often the dulness is of irregular shape, and dependent upon thick layers of plastic pericarditis, indicating its existence by coarse friction and by the sounds of the heart being much the same at the apex and at the base. This form of pericarditis without liquid effusion is, indeed, com- mon in childhood. So is pleurisy as an attendant upon acute rheumatism common, and not only single pleurisy, likely then to be left-sided, but double pleurisy. One of the dangers o'f left-sided pleurisy is that the inflammation is apt to spread to the pericardium ; at all events, whether from contiguity or from simultaneous action of the rheumatic poison, pleurisy and pericarditis are often combined, and both may be of the exudative plastic variety rather than attended with effusion. Still, effusion does happen in rheumatic pleurisy, and may be of slow absorption or become purulent. Pneumonia rarely complicates the pleurisy ; when it does, it may only reveal itself by rise of temperature, with- out marked cough or expectoration,- and by the physical signs. Cheadle believes that these are different from those of pneumonia in the absence, except in the embolic form of the malady, of fine crepitation. Chorea bears a very close relation to the rheumatism of childhood. Rheu- matic children are very apt to be irritable, nervous, emotional children, and 24 370 A3IERICAN TEXT-BOOK OF DISEASES OF CHILDREN. therefore witli nervous systems predisposing to chorea. The chorea associated with acute rheumatism has, in my experience, most generally shown itself toward the end of the attack and when the acute symptoms have disappeared. In the majority of instances there has been pericarditis or endo-pericarditis. Sometimes the choreic movements begin at the height of the malady, or the chorea even precedes the joint affection. It must further, in estimating the relation of chorea to rheumatism, be borne in mind that chorea does not always follow an acute attack, but may come on in those of rheumatic taint, Avithout previous well-defined rheumatic manifestations. Giitaneom eruptions are often seen in the rheumatism of childhood. The most common form is erythema, which appears on the limbs and the body, and is of the papulated or marginated form, or shows itself as urticaria, less often as erythema nodosum ; in rare instances it is purpuric and associated with sub- cutaneous haemorrhages. Barlow has pointed out that the erythematous rashes may appear simultaneously Avith pericarditis, or precede this and the articular symptoms. But more important tlian these rashes, and much more strictly linked to rheumatism, are the fibrous nodules. Of extreme rarity in adults, they are not uncommon in children. They are mainly to be found about the joints, are hard and painless or slighly tender on pressure, of size varying from a pin's head to a cherry, and are chiefly to be ascertained by the touch. They come and go in a few weeks, though they may last for months. It is not unusual to have them appearing in crops, and, though these subcutaneous nodules may project from the surface, the skin over them is not discolored. The}^ are almost constantly associated with endocarditis or with pericarditis, and Avhen abun- dant and freciuently recurring imply a progressive cardiac affection. Among disorders Ave frequently meet with in the rheumatism of child- hood is tonsillitis. It is often antecedent to the rheumatic attack or occurs in its course, and is combined with decided rise of temperature and pain in swallow- ing. It is not followed by either ulceration or suppuration. The ancemia that attends the rheumatism of childhood is very pronounced, and persists long after the attack. Where successive rheumatic seizures occur it becomes more and more decided, and is often associated w^th marked irrita- bility of the nervous system and emotional disturbance. In its persistence it may become a factor in the mischief wrought by a heai't disease and in the development of dropsy. Diagnosis. — Tiie diagnosis of acute rheumatism in a child is more difficult than in an adult, because the joint affection is often very slight, and may be nothing more than mere stiffening attended Avith moderate fever, or pain in moving certain muscles and tendons. Under these circumstances we have to lay great stress on the family history, on the character of previous seizures, on the occurrence of attacks of tonsillitis. Signs of endocarditis or pericar- ditis, or pleurisy, or erythematous rash, or nodules, Avould be conclusive. In some instances, too, epistaxis, an occasional symptom of the rheumatism of childhood, is very significant ; so is chorea. Endocarditis or pericarditis in a doubtful case Avould be. hoAvever, the most certain of proofs. When the joint affection is distinct, scarlatinal rheumatism is the disease most likely to be confounded with ordinary acute rheumatism. As regards the symptoms I know no difference ; heart affections in scarlatinal rheumatism are less common, but they arise. I have sometimes thought the absence of sweating diagnostic, but the acid sweats of rheumatic fever are also often absent in the rheumatism of childhood. Nothing but the antecedent his- tory makes the case absolutely certain. The severe pain and the swelling RHE UMA TISM. 371 of the joints sometimes observed in cerebro-spinal fever may cause this to be mistaken for rheumatism. But the violent headache, the retracted head, the rosv or petechial eruption, the irregular temperature and pulse, are very different from the combination of symptoms noticed in rheumatic fever. In its earlier stages rickets may mislead, on account of the swelling near the joints, the pain, the sweats, the fever. Yet the absence of redness of the joints, the size of the epiphyses, the undisturbed heart, the cachexia, the pale urine, and the fact that the wrist-joints are apt to be the ones first disturbed, or that the swelling; shows itself chiefly on the dorsum of the foot and on the back of the hand, are full of significance. From p3'a3mia, rare in children, rheumatism differs by the irregular fever of the former, the sweats, the great pain and swelling that are found in only one or in a few joints, and the course of the disease. There is a py?emic arthri- tis to which infants are liable, that Townsend has well described, which runs an acute course, is mostly confined to the hip or knees, and in which the effusion speedily becomes purulent. Its occurrence in infants at the breast or when gonorrhoeal ophthalmia or vaginitis is present also distinguishes it. Scurvy may present pain and swelling of the joints ; the absence of fever and the condition of the gums tell us that it is not rheumatism. In congenital syphilis the state of the bones near the joint may lead to the thought of rheuma- tism, but the characteristic eruption, the snuffles, the emaciation, the enlarge- ment of the spleen, the rarity of fever, and the fact that the symptoms arise in early infancy are diagnostic. The diagnosis of the most dreaded affection in rheumatism, the endocar- ditis, presents the same points for consideration as it does when it is not of rheumatic nature, and is discussed in another part of the volume. I will only here mention how important it is to remember the anaemic state that rheuma- tism develops in the young, and not to regard every murmur arising in its course, and especially when it has nearly run its course, as organic and as likely to lead to permanent valve-injury. These soft, systolic blood-murmurs are unconnected Avith change in valve or in muscular texture, and gradually pass away. Course and Duration. — The course of acute rheumatism in childhood depends very much upon the complications, especially upon the cardiac lesions. Nor do we find as many frank cases running their course in a definite time ; the cases are mostly subacute, with subsidences and fresh outbreaks. On the other hand, in infants there are instances of very rapid progress. Jaccoud's cases in infants soon after birth terminated, one in eight days, the other in little more than two weeks. As a general rule, the rheumatic fever of child- hood lasts between two and three weeks. Slight cases, Steiner estimates, get well in from ten to fourteen days. Goodhart's results in ten cases, of which he stated that the longest duration was four days, is not the general experience. It is difficult to be precise in this matter of duration, since much depends upon how early the patient has come under treatment and how well he responds to treatment. Under the salicylates we see the duration often much abridged, in instances particularly of joint affection without internal lesions. Where the heart is affected the case frequently runs on for five or six weeks. Frank relapses are not common. But a succession of subacute attacks in rapid suc- cession, affecting the joints but slightly while adding to the mischief in the heart, is not uncommon. Prognosis. — This is favorable ; few die in the disease. Certainly this is true of the first attack ; if the attacks be repeated, there is much more danger during the acute seizure. And the danger, again, depends rather upon the 372 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. condition of the heart than upon the mere recurrence of the rheumatic fever. The liability to cardiac disease increases with the number of attacks. Yet this docs not ahvays happen. I have mentioned a case in which three severe attacks happened without heart implication ; and A. Clark tells of one in a boy of twelve in which eight attacks occurred, the heart remaining sound. Such instances are, however, very exceptional. Age has something to do with the prognosis. Of cases between one and ten years of age, 83 per cent., McPhe- dran calculates, have heart lesions ; between ten and twenty, 69 per cent. In 54 fatal cases of rheumatic heart disease Sturges encountered none under two years of age; 42 out of the 54 happened between six and twelve years. Embolism and thrombosis are rare, but very grave. The chief concern where cardiac affections exist is as regards the amount of mischief that will remain after the acute symptoms have subsided. A murmur indicative of mere roughening of the valve may in the course of a few months disappear. But very often it persists, and gradually, if the lesion have been more than mere roughening of the valve, the signs of hypertrophy with dilatation become manifest. This may not happen from the first attack ; but during slight recurring rheumatic seizures — slight at least so far as the joints are con- cerned — the heart affection is little by little added to ; or this is aggravated by a more severe attack, in which a fresh extensive endocarditis occurs. From pericarditis we may have the same consequences as in adults — adherent peri- cardium with hypertrophy or dilatation ; considerable effusions are very rare. Rheumatic pericarditis by itself has a better prognosis, both at the time and in its ultimate consequences, than endocarditis. But with reference to the latter it must be borne in mind that it is mostly associated Avith some pericarditis, really an endo-pericarditis ; for few are the cases where endocarditis of rheu- matic origin alone exists. Persistent anaemia after rheumatic endocarditis or pericarditis is always a bad sign. The hypertrophy or dilatation, which under any circumstances happens more rapidly in children than in adults, gains at increased rate. The frequent occurrence of fibrous nodules is a sign of danger, as fresh mischief is apt at the same time to be wrought in the heart. It is then here, as it is throughout in acute rheumatism, the heart, after all, that chiefly determines the prognosis. Chorea is rarely a serious complication. The joint affection mostly passes off completely; rheumatic thickening and anky- losis are very seldom seen in childhood. Treatment. — The treatment of acute rheumatism in a child is the same as in the adult. The greatest care must be taken to keep the patient at rest and from being chilled, and with this view the child should be kept in bed in a flannel night-dress or between blankets. The diet should be at first chiefly farinaceous, with bread and moderate amounts of milk ; later in the disease broths and fish may be allowed. Of medical remedies, the most prominent is salicylic acid or its compounds ; among these, salicylate of sodium or of ammonium is well adapted. The dose to a child five years of age is thirty to forty grains in divided doses in twenty-four hours; to^a child of ten, sixty to ^ig^ty grains. It may be given in syrup of orange, or in simple syrup with spirits of lavender. The salicylates relieve the joint affection and the pain, and their action is rapid ; after the third or fourth day the dose may be dimin- ished one-half or more. If no result be seen from them in three or four days, they are not likely to produce any, and some other remedy had better be administered. Nor ought they to be trusted to where heart complications exist. Further experience, indeed, both in children and in adults has only added to my conviction, expressed some years since, that the salicylates neither prevent pericarditis or endocarditis, nor benefit its course after "it has set in. Their RHEUMATISM. 373 chief use is where there is much pain and the joint affection decided; and it is always well in any case to give- also alkalies from the start. When the circulation becomes depressed, or buzzing in the ears or giddiness occurs, the salicylates should be at once discontinued. Salicin is by some recommended as less objectionable, in doses of from five to eight grains every third or fourth hour to a child of five, after the salicylates have been administered for a day or two, or even from the beginning. Under any circumstances, in instances of heart complication or where a heart lesion has existed from a previous attack, the alkalies are vastly prefer- able remedies. It is, indeed, to decided doses of the alkalies that we must trust. Fifteen to twenty grains of bicarbonate of sodium in simple syrup and mint- water every third or fourth hour to a child eight or ten years of age, or two drachms of the acetate of potassium in divided doses in the twenty -four hours, form the proper average dose. These alkalies should be administered until the urine becomes alkaline or neutral, and then enough be ordered to keep it neutral. Quinine is very valuable. It may be given in decided doses when the tem- perature tends to run high, as, however, it is not apt to do in children unless there be endocarditis or pericarditis. In doses of about six grains daily to a child five years of age it is an excellent remedy when the more acute symptoms have subsided, whether the alkaline or the salicylate treatment be the one pursued. Opium is another remedy of great value. It allays restlessness and pain and procures sleep. In coexisting endocarditis or pericarditis it may be directed in small, continuous doses, and is indispensable. The bromides relieve rest- lessness and excitability, and are not without infiuence on the course of the disease. Conjoined to chloral, they give rest at night; and Goodhart lauds the combination of five grains of the bromide of potassium and one or two of chloral as almost a specific for the nightmare of rheumatism in young children. The treatment of the main internal lesions, the endocarditis and the peri- carditis, is discussed in another part of this volume. I will only here speak of my favorable experience in pericarditis with brandy or whiskey in decided quantities, and with opium. The pleurisy is treated as all pleurisies are ; the iodides are especially applicable to the plastic form. The salicylate of sodium has been recently highly spoken of in this kind of pleurisy ; I have had no experience with its use. In the tonsillitis of rheumatism the salicylates give quick results. The local treatment of rheumatism consists in wrapping the aff"ected joints in cotton wool, or, where they are very painful, in a flannel bandage saturated with a solution of nitrate of potassium, one to two drachms to the ounce, to which laudanum, twenty drops to the ounce, has been added. For lingering swelling of the joints the rubbing in of iodine, ten to twenty grains to half an ounce of lanolin and half an ounce of belladonna ointment, is well adapted. During convalescence iron is strongly indicated ; and there should be then, as always in rheumatic children, the greatest care exerted with reference to warm clothing, to the food being of easily digestible kind, and to the avoidance of exposure to cold and damp as well as to fatigue and over-exertion. n. Muscular Rheumatism. This is met with in children, as it is in adults, mostly following cold and exposure, especially exposure to draughts, or fatigue. The disorder is generally subacute, and attended with but little constitutional disturbance. The prom- 374 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. inent symptom is pain in moving the parts involved. It is very rarely a general disorder, but is limited to particular groups of muscles. We find it in the del- toid ; or in the muscles of the loins, as lumbago ; or giving rise to stiff neck, as torticollis ; or involving the intercostal muscles and restricting the acts of breathing, as pleurodynia; or in the muscles of the head, as cephalodynia. Wherever it is, it has the same characteristics — pain on motion, slight tender- ness, little if any fever. Not unfrequently the urine is high-colored and full of urates. Diagnosis. — In the diagnosis of the affection we have to distinguish it from neuralgia. The stricter limitation of the pain of neuralgia to particular spots, and its passing along special lines of nerve-distribution, the far less influence motion has on it, form, broadly speaking, the traits of distinction. We must also not be misled in considering as muscular rheumatism "growing pains," or the pains of aching muscles after unusual exercise. Prognosis. — The prognosis is always favorable. The main object, when the immediate attack has been remedied, is to prevent recurrences. Treatment. — Rest of the affected muscles, the application of warmth by hot fomentations or the hot-water bag, the use of liniments containing chloral, chloroform, or opium, are all beneficial. Atropine and morphine hypoder- matically, so valuable in adults, cannot be so generally employed in children. Diaphoretics are always serviceable ; a combination of nitrate of potassium and Dover's powder is eminently so ; and in lingering cases the bromide of ammo- nium or the iodide of potassium or of ammonium is of distinct benefit. So is the continuous current. Jacobi considers that the best preventive is the habit- ual use of cold water. m. Chronic Rheumatism. Chronic rheumatism, as we see it in adults, is rare in children ; certainly long-continued stiffness of muscles and chronic enlargement of joints are rare. As already pointed out, recurrence of short attacks with stiffness and pain is the form in which the persistency of rheumatism in childhood much more generally shows itself. The few cases that, present the same appearances noticed in the chronic rheumatism of adults may be mistaken for rheumatoid arthritis — a disease which is not unknown in childhood, though it is rarely spoken of. The previous history of the case, the occurrence of rheumatoid arthritis in those of feeble health, the wasting of the muscles, the enlarged, crepitating, or fixed joints with the gradually developing characteristic distortion of the fingers and toes, and the absence of all tendency to cardiac affection, are significant in the distinction. In the treatment of chronic rheumatism the chief remedies are the iodides, the muriate of ammonium, and arsenic, with great attention to general health and thorough protection by dressing warmly. Using iodine to the affected joints or rubbing them with ammoniated liniments, or, if there be effusion or bony thickenings, small blisters applied from time to time, will give the best results. Good is also done by massage, and by warm baths with carbo- nate of sodium dissolved in them, or by a recourse to the sulphuretted and alkaline mineral-Avater springs that have been found to be of real service in the chronic rheumatism of adults. PART Y. DISEASES OF THE BLOOD. ANAEMIA, SPLENIC ANAEMIA, LYMPHATIC ANEMIA, AND LEUKAEMIA. BY FREDERICK A. PACKARD, M. D., Philadelphia. While in most respects the blood of infants and children resembles that of adults, there are in the blood of the new-born a few variations from the adult standard which require mention. During the first twelve days of life the blood has a somewhat venous appearance when seen in bulk. In the new-born child the red blood-corpuscles are of much more unequal size than they are in older children and in adults, the largest of them being larger, and the smallest, smaller. During the first four days of life there are to be found a varying number of nucleated red cells. These soon disappear, although some observers claim that they are to be found up to the second or third year. Owing, presumably, to the ready solubility of the haemoglobin in young infants, numerous "shadows," or red blood-cells that have lost their hgemo- globin, are present. The red cells are more easily affected by reagents than is the case in adults, moisture in particular causing them to very readily assume the spherical form. The number of red cells is proportionally larger in the newly-born, the count varying, according to different observers, from 4,300,000 (Bouchut, Dubrisay) up to 7,500,000 (Gundobin) per cubic milli- metre. The daily variations in their number are -very marked. There is marked increase in the number of colorless blood-cells in young infants as compared to adults. The subject of the relative number of the dif- ferent forms has been most carefully studied by Gundobin {Jahrh. f. Kinder- heilk. u. pJiys. Urziehung, Bd. xxxv. Hffc. 1 and 2, Jan., 1893). According to this author, the relative percentage of lymphocytes in sucklings is three times as great as in adults, while the neutrophiles are relatively twice as small in number. From the seventh to the tenth day is the period at which the rela- tive and absolute numbers attain the proportions maintained in later life. The amount of hgemoglobin is greater in young infants than in adults. This relative increase is maintained for some weeks, at the end of which time it begins to diminish, until at about the middle of the first year it has reached its lowest point, thereafter slowly increasing to the normal of adult life. The specific gravity is said to be high immediately after birth (1.066), but it soon sinks to a little below that of adult blood. Plethora. — It is now granted that, while this term may be used as a con- venient means of describing certain conditions, it is not accurate, in so far as 375 376 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. it implies an actual increase of the total mass of blood or of its corpuscular elements. The term was employed to indicate a condition formerly supposed to be due to '• full-bloodedness," but now known to be a condition wherein the appearance of vascular turgescence is due not to any over-richness in blood, but to local changes in the superficial vessels. That a relative increase above the normal of the number of red blood-corpuscles can exist is true only in conditions where the watery constituents are decreased, as in cholera. To this condition the term "plethora " is manifestly inapplicable, the loss of fluid merely increasing the number of corpuscles in the drop. ANEMIA. Anemia is a condition of the blood due to a decrease in its richness in either corpuscular elements or haemoglobin, either from primary disease in the blood-making or blood-destroying organs, or, secondarily, from general or local disease that interferes with normal absorption, metabolism, and assimilation, or is productive of abnormal loss of nutritive material from the body. In the above definition an?emia is spoken of as a condition instead of as a disease, since in the vast majority of instances it is merely a symptom of some well-recoghized disease of the whole body or of individual organs. The anae- mias produced by morbid processes that are recognizable as distinct diseases are spoken of as secondary, whereas those occurring without apparent cause save disease of the blood-making or blood-destroying organs are spoken of as primary. In the latter class we must still place chlorosis, progressive per- nicious anaemia, splenic anaemia, lymphatic anaemia (Hodgkin's disease), and leukaemia. SECONDARY ANEMIA. Etiology. — Our knowledge of the process of blood-formation and blood- destruction is not sufficiently advanced to explain the production of anaemia in all cases in which it occurs. Where actual escape of blood from the blood- vessels takes place, the explanation is, of course, manifest ; but it is far from evi- dent in exactly what manner prolonged high temperature, loss of albumin from continued suppuration or Bright's disease, the rheumatic poison, and certain toxic influences produce decrease in the richness of the blood in corpuscles or haemoglobin. In childhood the chief causes of secondary anaemia, aside from those operative equally in adult life, are due to improper hygiene as to diet, exercise, and ventilation. A frequent cause is mucous disease, which seems to act by preventing the proper digestion, absorption, and assimilation of nutri- tive material. Improper articles of diet and improperly prepared food may act in practically the same way; that is, by a failure to supply nutritive material proper to the needs of the body. Too rapid growth is capable of causing anae- mia, the frame seeming to outgrow the quantity of blood manufactured, just as it is apt to become too large for the functional' capacity of certain organs. In addition, we must recognize the fact that in some individuals a condition of anaemia seems to be a constitutional characteristic, and to be not incompatible with a fair degree of health. Malaria, as a cause of anaemia, seems to act with even greater intensity in children than is the case in adults, while the anaemia of acute rheumatism at times reaches an extreme grade. Further than in these respects the secondary anaemia of childhood difiers in no way etio- logically from that in adult life. ANu^MIA. 377 Symptoms. — The general appearance of a child with simple anemia is too well known to require description. The white skin, pallid mucous mem- branes, waxy appearance of the nails, and blueness of the white of the eye are seen in children as plainly as in adults, if not more so. The subjective symptoms of anaemia do not attain much prominence in childhood, as not only is the child less well able to express its sensations than is the adult, but also because it simply ceases to play around or to exert itself when it feels the sub- jective sensations produced by anaemia, instead of being compelled, as is the adult, to struggle against discomfort in the endeavor to continue the duties of life. One of the most frequent symptoms observed in children is the tendency to syncopal attacks. These may occur apparently causelessly, or may be readily induced by violent emotion, slight pain, or confinement in a poorly ventilated apartment. Shortness of breath upon exertion is also frequently present, although in children too young to feel the stimulus of competition this may be shown merely by an indisposition to exertion. Rarely, except in cases of extreme degree, is any oedema discoverable. The haemic murmur at the apex or base does not seem to be produced in children so readily as is the case with adults. The examination of the blood shows a reduction in the red blood-cor- puscles, with a corresponding diminution of haemoglobin ; that is to say, the valeur glohulaire does not differ from the normal. In extreme cases poikilocy- tosis may be observed. A relative increase of white blood-cells as compared to the red may be present, owing to the reduction in number of the latter. Diagnosis. — There is, as a rule, no difficulty in determining the existence of simple anaemia, but the diagnosis cannot be considered as complete until the cause of the poverty of the blood has been detected. The question of the causative factor in simple anaemia of the young requires not only a careful examination of the child itself, but a minute scrutiny of all of the hygienic surroundings. The differential diagnosis between simple, secondary anaemia and that of chlorosis and of pernicious anaemia is readily made by an examination of the blood. In simple, secondary anaemia blood-corpuscles and haemoglobin are reduced together, and to an almost equal extent, whereas in chlorosis the haemoglobin reduction far exceeds that of the corpuscles, and in progressive pernicious anaemia the corpuscular poverty exceeds that of haemoglobin. From splenic anaemia the diagnosis must be made by the detection of a cause other than the enlarged spleen. Prognosis. — This depends entirely upon the cause. The anaemia itself rarely reaches a degree sufficient to cause anxiety. Treatment. — While removal of the cause, when possible, is the prime object of treatment, we may frequently combine our symptomatic treatment of the anaemia with the hygienic and medicinal treatment of the previous affection. Good, nourishing food in quantity and quality to suit the age of the patient and the condition of the digestive organs, abundance of fresh air, and an amount of exercise adapted to the primary disease and to the strength of the patient are all-important aids in treatment. For the purpose of increasing the richness of the blood in corpuscles and coloring matter we have two drugs upon which reliance can be placed, iron and arsenic. In employing iron it is important to remember its marked tendency to interfere with digestion, and in cases dependent upon gastro-intestinal dis- turbances Ave can frequently increase the lacking blood-elements more rapidly by first correcting the digestive troubles, when, indeed, the iron may not be 378 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN, required at all. The best forms for its administration to children are the syrup of the iodide of iron, reduced iron, or one of the vegetable salts of iron. The dose of whatever preparation may be selected should be carefully regulated to the age of the patient, and the drug should be discontinued or its amount lessened when it produces constipation or when the stools are distinctly dark- ened. In this form of anaemia it is unwise to give more iron than can be absorbed and utilized, whereas in chlorosis even the iron that is voided with the fteces seems to have been of some utility. Arsenic is of great value as a restorer of the red corpuscles, probably by its action upon the blood-making organs. It is pre-eminently useful in the antemia of chronic malarial poisoning, and is of marked value in the later treatment of mucous disease with ansemia. It is often well to combine iron and arsenic, as they seem to virtually assist each other in many cases ; some such form as the following may be employed : I^. Liquor, potassii arsenitis f^j. Syrup, ferri iodidi foix. — M. Sig. Ten drops thrice daily. THE PRIMARY ANAEMIAS. Chlorosis. AVhile essentially a disease of youth as opposed to childhood and infancy, this disease is occasionally met with before the former period of life is reached. It is therefore proper that it should find a place in a work upon pediatrics. Etiology. — While much has been written upon the essential cause of this condition, it cannot as yet be said that the etiology is by any means definitely settled. The theories reorardino- it are too numerous to be even enumerated. The most satisfactory explanation is that the excessive destruction or imperfect formation of haemoglobin is due to either the defective absorption and assimila- tion of iron from the intestinal tract or to the absorption from the bowel of poisonous principles with htemolytic properties. The view advocated by Vir- chow that it is caused by congenital hypoplasia of the vascular system, and the view that it depends upon developmental imperfection of the genital apparatus, cannot be considered as tenable considering the rapid and complete cure fol- lowing the employment of proper hygienic and medicinal treatment. Age is an etiological factor of great importance, most of the cases occurring between the thirteenth and twentieth years of life. Instances have been observed, however, in individuals even below the former age. Sex has a strong determining influence, the vast majority of cases occur- ring in females, and but light grades of the affection being seen in boys. Hered- ity cannot be said to have any but a predisposing influence, and even that is doubtful, although Trousseau and others claim that the disease is very frequent in tuberculous families. Habits of life play an important part in its production, the overworked with but little opportunity for the enjoyment of fresh air, exercise, and mental relaxation being those most frequently affected. Depressing emotions, sexual abuse, and fright seem to act as causes, either directly or remotely. The menstrual disturbance so frequently seen in connection with this particular alteration in the composition of the blood must be looked upon as a result rather than as a cause. Symptoms. — The complaint that induces a patient with chlorosis to seek ANEMIA. 379 medical advice is variable. Sometimes it is the shortness of breath upon exertion, at times the interruption of the menstrual periods, and at times the cephalalgia. The usual history given is that the patient has suffered from vertical headache for a variable time, with shortness of breath upon exertion, palpitation, marked lassitude, and frequent fainting-spells. The date of appear- ance of the several subjective sensations is as variable as is their relative intensity. The symptoms above enumerated are those most constantly present. Constipation is usually marked, and a desire for unnatural articles of diet is at times a prominent feature. Gastralgic attacks are frequently present. The appearance of the patient is extremely characteristic. The skin has a peculiar olive tint, which, taken in connection with the pale lips, is imitated by no racial peculiarities of coloring. There is apt to be a certain ashy appear- ance about the angles of the mouth. The expression is usually languid with an appearance of sadness, while the features frequently show some heaviness of outline. There is a variety of chlorosis, first described by Wendt, wherein the cheeks retain an abnormally red color — chlorosis florida seu rubra. Occa- sionally a deposit of pigment in the neighborhood of joints is observed. The mucous membranes are pallid to a varying degree according to the extent of the anaemia. There may be slight puffiness beneath the eyes, and the feet or ankles may show slight oedema with but little pitting upon pressure. Marked oedema is, however, rare. There may be visible pulsation of the vessels of the neck. The subcutaneous fat is seldom decreased ; in fact, the condition of emhoyipoint is that most frequently seen. The pulse is usually rapid and compressible. The apex-beat of the heart is usually plainly visible, and more diffuse than in health. Auscultation reveals, in all marked cases, a soft blowing murmur at either the apex or base, or both, with sharply-defined and somewhat valvular first sound. Over the veins of the neck there is almost always to be heard a loud venous hum. Thrombosis is apparently rather favored by the condition of the blood. The examination of the blood is of itself sufiicient for a diagnosis. The characteristic change is a marked decrease of the percentage of haemoglobin. With a corpuscle count of 4,500,000, or even over 5,000,000, per cubic mil- limetre the haemoglobin may be decreased to 50 or 40 per cent, of the normal. Less characteristic appearances are the pallor of the drop as it flows from the finger and the variety in the size and shape of the red blood-cells when seen through the microscope. The genital apparatus is usually said to be undeveloped. I have, however, seen within the past year a chlorotic, aged fifteen years, with mammae, areolae, and nipples of the size and appearance of those seen in adult life. The urine presents no changes of note save in that it is of low specific gravity and pale in color, contrasting strongly with the low specific gravity and dark color of the urine in cases of pernicious anaemia. Albumin in small quantities is occa- sionally found. Morbid Anatomy. — There have been no distinctive lesions found in the few fatal cases that have come to autopsy. The narrowness of the arteries with the small size of the heart noted by Virchow, and the presence in some cases of a poorly-developed uterus and its appendages, are all that have been noted aside from the apparent bloodlessness of the organs and the retention of a fair amount of adipose tissue. In some cases the left ventricle has been dilated. No alterations in the blood-forming organs have been reported. Diagnosis. — As has been said, the appearance is characteristic. The tint of the skin is quite different from the yellowish-brown stain of jaundice and from the lemon-yellow tint of pernicious anaemia and the cachexiae. The 380 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. sclerotics are of a clear blue color, in contradistinction to the yellowish colora- tion of icterus. From these as well as other diseases the blood-examination will separate this affection at once. From pernicious anaemia and Bright's disease the absence of retinal disturbances would readily distinguish it; while in the for- mer the examination of the blood is as characteristic as it is in chlorosis, and in the latter the presence of tube-casts and absence of oligochromaemia are points of plain significance. Prognosis.— The outlook is extremely favorable, providing only that patients can be persuaded to continue treatment until absolute cure is estab- lished. The tendency to relapse is very marked, and patients frequently cease their visits when their most marked symptoms have been relieved, only to return in their former condition after the lapse of a few weeks. The disease is but very rarely fatal, and the unfavorable result is due to the onset of some incidentaf affection. The only complication of note is gastric ulcer, and this is seen but rarely. Permanent disease of the heart may result in protracted cases. Treatment. — This is most satisfactory if the patient persist in treatment until cure is complete. Hygiene plays an extremely important part. Plenty of fresh air, with moderate exercise and a plain but nourishing diet, will do much to hasten the cure. In some cases absolute rest in bed with milk diet seems to act well, par- ticularly in the more severe and obstinate cases. The daily use of the flesh-brush upon rising in the morning is of value, not only in relieving the coldness of the extremities that is often present, but in improving the general nutrition. In vigorous subjects cold sponging before breakfast will help to increase the general tone of the system. The bowels must receive careful attention. Daily evacuations should be procured by regu- lation of the diet, the use of "cannon-ball "' massage to the abdomen, and. if necessary, by the use of tonic laxatives. Of the latter, the best by far is aloes or aloin. The latter may be made up into a pill with extract of nux vomica and extract of belladonna, and should be taken at bed-time. The pill of aloes and myrrh of the United States Pharmacopoeia is an excellent combination for older subjects. The specific remedy for the disease is iron. The simpler the form in which it is given, the better. The most satisfactory is in the combination known as Blaud's pill (]^. Ferri sulphat. exsiccat., Potas. carb. (pur.), del gr. iij). This may be given after meals, increasing from one to three times a day, to two pills three times daily in the first ten days, and maintaining or even increasing this number until the haemoglobin has reached the normal amount. Where objection is made to taking pills, as is frequenth' the case among the class in which this disease is most prevalent, powdered iron may be readily given. The great point is to give the drug steadily and unremittingly until the haemochromsemia has been absent for one or two weeks or even longer. Progressive Pernicious Anemia. This is an intense, generally progressive, alteration of the blood arising spontaneously, characterized clinically by the symptoms and signs of marked amemia, by diminution of the number of the red blood-corpuscles without cor- responding decrease in the amount of haemoglobin, and by an almost invariably fatal result. The name of this condition must be looked upon as being provisional. It ANEMIA. 381 is probable that in the future some more definite knowledge may be obtained that will enable us to separate the cases now grouped together under the above title into separate classes depending upon etiological factors that are at present unknown. Formerly cases were grouped under this title that are now known to be separate pathological processes, of which the anaemia was merely a symptom, notably those of atrophy of the gastric mucosa and those due to intestinal parasites. At present, however, we must include under one name a class of cases that 'have no apparent causation in organs other than those immediately concerned in blood-formation, and which still present a uniform grouping of symptoms. Etiolog-y. — The actual cause of this disease is as yet unknown. The researches of Quincke and Peters upon the excess of iron found in the liver of patients dying of it, and the observations of Hunter upon the dark color of the urine from the presence of pathological urobilin, would point to the existence of some cause for an increase of haemolysis. Whether this be a poison created within the body has not as yet been proven, but from the remarkable resemblance between this and the anaemia from atrophy of the stomach it is at least possible to suppose that the haemolysis may be produced by the absorption of some toxic principle from some portion of the alimentary tract. Age is a marked etiological factor, inasmuch as the large majority of cases occur during middle life. That it does occur in young persons with moderate frequency is shown by the fact that cases have been collected by Griffith,^ wherein the disease has occurred at the ages of sixteen months, three, five, seven, eight, ten (2 cases), eleven (2 cases), twelve, fifteen, and eighteen years, and in one other boy in which the age was not given ; while I have found additional cases reported as pernicious anaemia, without an exhaustive search of the literature, at ages of eleven months,^ one year and four months,^ two,* four,^ eleven (2 cases)," thirteen,^ fifteen,^ sixteen,® seventeen,^" and twenty^^ years. The female is rather more prone to the disease than is the male sex. In one of Escherich s cases the appearance of the disease followed close upon vaccination with animal lymph, but whether there was any relation between the two events it is impossible to say. Symptoms. — The most striking subjective symptom is extreme and pro- gressive weakness. Shortness of breath and vertigo soon become prominent symptoms. While feeling extremely ill, the patient retains a fair amount of fat, and save for extreme pallor has the appearance of a well-nourished indi- vidual. The weakness and pallor increase gradually with, at times, temporary short intervals of apparent improvement. Dyspnoea increases, the extremities become oedematous, and the patient is at length compelled to remain in bed, ^ Keating's Cydopcedia of Diseases of Children, 1890, vol. iii. p. 809. ^ D'Espine and Picot {Revue de Med., 1890, p. 859) : blood-count not given, doubtful. ^ Ibid. : blood-count not given, probably a true case. * Escherich ( Wiener klin.

Record, 1888, p. 407). 382 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. the Avliole body being sometimes water-logged with anasarca. Occasionally irregular elevations of temperature arise without apparent cause. Gastro- intestinal disturbance may be present, but in cases unassociated with gastric and intestinal atrophy they sink into insignificance in comparison with the intense languor and shortness of breath. Haemorrhages from the mucous membranes and beneath the skin are sometimes present and may be profuse. As a result of treatment or without apparent cause, the condition may for a time improve, but the course is usually progressively downward until death occurs from simple asthenia, possibly hastened by an attack of intestinal dis- turbance or by the onset of some acute inflammatory trouble. The appearance of the patient is almost pathognomonic. The skin is of a peculiar pale-lemon tint, the lips almost white, the conjunctivae of a pearly whiteness. Areas of pigmentation may be present on various parts of the body. The retention of a fair degree of embon2?oint with the extreme pallor at once sugcpests this disease to one who has seen a case thereof. Upon phj'sical examination nothing abnormal may be found save soft hjiemic murmurs at the apex or pulmonary cartilage and venous murmurs in the neck. The pulse is soft, readily compressible, and gives an impression to the finger similar to that of aortic regurgitation, which disease this also some- Avhat resembles in the occasional presence of a capillary pulse. The urine is peculiar in that with low specific gravity the color is quite decided — due, according to Hunter, to the presence of pathological urobilin. Upon ophthal- moscopic examination streaks of hsemorrhagic extravasation are frequently to be seen. The examination of the blood is of itself sufficient to determine the dia- gnosis. The blood as it exudes from the finger is usually of a paler color than normal, and may be obtained only with great difficulty. Upon examining a fresh specimen there is found to be extreme irregularity in the size and form of the red cells. There are seen in the same field numerous red cells smaller than the normal, side by side with others of double the size of the latter. Nucleated red cells of large size are also seen. There is little tendency to the formation of rouleaux. The red blood-cells are far below the normal average per cubic millimetre. Their number varies much with the duration and severity of the individual case : it may sink to below 500,000 per cubic millimetre. The estimation of haemoglobin shows that this is in excess of the amount corresponding to the cellular reduction. This disproportion of the number of red cells and the amount of hemoglobin is characteristic of the disease — the valeur globuJaire is exceedingly high. Morbid Anatomy. — The skin is generally of a markedly yellowish-white color. The subcutaneous fat is usually remarkably well preserved and is of a light-yellow color. The muscles are peculiarly red, in marked contrast with the pallor of other tissues and of the muscular tissue in other forms of anremia. All of the internal organs look blanched, but upon the various serous mem- branes ecchymotic areas are frequently seen. Punctiform haemorrhages may also be present in the skin, mucous membranes, connective tissue, muscles, heart-wall, bone-marrow, lymph-glands, spleen, liver, pancreas, lungs, and dura mater. They are due, according to Bermer, to fatty degeneration of the capillaries, although other observers have failed to find the change described. In the serous cavities a varying amount of clear serum is present." The heart is usually large and soft, its walls flabby, its chambers almost empty of blood. "Tabby-cat mottling" of fatty degeneration is frequently present, or the whole tissue may be pale and fatty-degenerated. The spleen shows no constant changes. The gastric mucosa may be found atrophied in some cases of appa- A])r^3fIA. 383 rently true idiopathic pernicious anaemia ; but these cases should not be classed under the name of the disease under consideration unless the view that atrophy of the gastric and intestinal glands is one of the results thereof. The liver is fatty, and shows the only really characteristic change of any of the organs. Upon microscopic examination there is found an excess of free iron in the cells of the outer and middle zones when the sections are treated with proper reagents. The kidneys may be the seat of marked fatty degeneration, and iron has been occasionally detected in the renal cells. The marrow of the shaft of the long bones is of a deep brick-red color, resembling the foetal con- dition, but the appearance is not characteristic, as it has also been found in other forms of anaemia. In the posterior columns of the spinal cord there has been found a process resembling in every respect that seen in locomotor ataxia. Diagnosis. — The chief difficulty in diagnosis lies in the exclusion of a primary cause for the anaemia. The appearance of the patient, the subjective symptoms, and the progressive course will usually lead to a correct diagnosis. An examination of the blood definitely decides the question. The diseases which most resemble pernicious anaemia are atrophy of the gastric tubules and malignant disease of the internal organs, particularly those of the digestive tract. Careful examination will usually exclude the latter even without an exam- ination of the blood. Certain cases of atrophy of the gastric tubules have so resembled pernicious anaemia as to render a distinction between them an impos- sibility. Unfortunately, in these cases the chemical examination of the gastric contents is of but little aid, as Ewald has found that hydrochloric acid is absent from the gastric juice in pernicious anaemia as well as in gastric atrophy, and the peptonizing poAver is diminished in both conditions. Prognosis. — The outlook is extremely grave. As a rule, death comes in spite of all our eiforts. A fatal result occurred one month after the first appearance of pallor in the two-year-old child reported by D'Espine and Picot, and in Kjellberg's case of a boy aged five years death occurred six weeks after development of symptoms. Recovery may be considered impos- sible if the red cells number 500,000 per cubic millimetre or less. Since the discovery of the value of arsenic in this disease the prognosis is somewhat less hopeless than formerly. By its use apparently hopeless cases may be at least temporarily relieved. Too often, however, the improvement is but temporary, and relapse soon takes place. Death comes from exhaustion or from the onset of some intercurrent disease. A sharp attack of diarrhoea or an inflammatory disease of the respiratory tract is frequently the immediate cause of death. Haemorrhage is rarely of sufficient amount to cause death Litten reports a case that apparently passed into leuksemia. Treatment. — Absolute rest with freedom from worry and excitement is of prime importance. A diet selected with care and adapted to the needs and capacity of the individual is to be directed. Among drugs none can equal arsenic in value. By its means the number of red blood-cells may be increased to within a fair degree of normal, and with corresponding amelioration of symptoms. It should be given freely up to the point of tolerance. It is better to begin with small doses well diluted, and to increase as rapidly as is consistent with the avoidance of toxic symptoms : upon the appearance of gastro-intestinal disturbance or of oedema either the use of the drug should be entirely discontinued for a time or the dose should be much reduced. The pigmentation occasionally seen in the course of the disease should not cause needless fear of arsenical pigmentation. Iron is but seldom of value. It may, however, be used in cases showing an intolerance to arsenic. Rectal 384 A3IEBICAN TEXT-BOOK OF DISEASES OF CHILDBEN. injections of blood prepared in various ways are no longer considered worthy of the hope that was at one time placed in them. The inhalation of oxygen may relieve the dyspnoea that is at times severe, but nothing more than palliation can be expected to result from its use. If the theory of intestinal absorption of ptomains in the causation of this disease be correct — and there seem many reasons for believing it to be so — rendering aseptic the intestinal canal would be a rational means of cure. It is well, therefore, to keep the bowels opened regularly, and to administer in appropriate quantities salol, thymol, or /9-naphthol in order to accomplish what we can in this direction. Splenic Anaemia. In a considerable number of children there is found a marked degree of anaemia associated with no appreciable lesion save enlargement of the spleen. Rendu has reported a case wherein, after the lapse of two years, an increase in the number of white blood-corpuscles occurred, and Gilbert saw a case that later was transformed into lymphatic leukaemia. Etiology. — Much discussion has been indulged in as to the cause of this form of antemia in childhood, and even now it cannot be said that any uni- formity of opinion has been obtained. Malaria is certainly capable, when long operative, of producing both ansemia and chronic splenic enlargement in chil- dren, just as in the case of adults. The cases presenting a malarial history comprise, however, but a very small minority of the cases in which this affection has been observed. The two diseases that appear to have most claims as etiological factors are rickets and inherited syphilis. Out of 30 cases, Carr found 27 with other distinctly rachitic lesions ; in 14 cases syphilis played at least a prominent part. In 60 rachitic children Kuttner found a palpable spleen in 44, in 33 of which the organ was markedly enlarged. In only 2 of the 60 cases was there a clear history of syphilis, but in 13 there was a history that the mother had had mis- carriages or stillbirths. In 63 cases examined by them, Fox and Ball found that rachitic symptoms were present in almost all ; and in one series of 105 consecutive cases of rickets the spleen was enlarged in 14 per cent. ; in another series of 84 cases of very marked rickets, enlargement was present in 40 per cent. That inherited syphilis may be more than a predisposing factor is rendered highly probable from further statistics furnished by the last-named authors. In 63 cases of enlargement of the spleen with anaemia they found inherited syphilis in 41 per cent. ; while in 155 cases of inherited syphilis the spleen was enlarged in 48.4 per cent. The influence- of hereditary syphilis in causing rickets should not be overlooked, and it seems more than likely that the most potent factor is rickets. It is interesting in this connection to learn that Sutton (according to Fox and Ball) has found both liver and spleen con- .>-tantly enlarged in monkeys, where rickets is produced by causes other than syphilitic taint. The disease would appear to be frequently found in members of the same family, partly due, no doubt, to the fact that the individuals were all subject to the same conditions of life. Boys are more often affected than girls, Kuttner having found it in 37 boys out of 60 cases. The disease has been seen at the age of two months (Carr) and in adult life, so that no definite statement can be made as to age as a predisposing factor. Pathological Anatomy. — The only characteristic lesions found relate to the spleen. The organ is enlarged, the capsule thickened and adherent, the ANJEMIA. 385 parenchyma firm, with marked increase of fibrous tissue. The microscopic examination shows increase of fibrous tissue, with atrophy of Malpighian bodies and disappearance of adenoid tissue (Peter). The marrow of the long bones may have become lymphoid in character. In the other organs various changes are to be found as coincidental affections. These are practically the lesions discovered after death in children with rickets or inherited syphilis. The most frequent abnormal conditions found relate to the respiratory organs. There may be bronchitis, atelectasis, pneumonic consolidation, or the deposition of tubercles. The gastro-intestinal tract may show the lesions of a chronic catar- rhal inflammation. Symptoins. — Lassitude and general weakness on the part of the child may be the causes of medical treatment being sought. In other cases the peculiar pallor may have called the attention of the parents to the child's condition. The enlarged spleen may have caused anxiety, or the child may have been brought for treatment on account of the catarrh of the respiratory or digestive tract that is a frequent accompaniment of the condition. The existence of the disease may be discovered accidentally in examining a child presenting other manifestations or rickets. The complexion is of a peculiar waxy, pallid hue, with rather a muddy tint. The mucous membranes are blanched, the tongue pale and flabby. Upon examination of the trunk there are found in rachitic children not only the prominent abdomen that is usually seen in children of this class, but there may be visible tumor in the hypochondriac and lumbar regions of the left side. Frequently the enlargement of the spleen may not be discovered until palpation reveals a resisting mass. In marked cases the spleen can be readily felt as a sharply-defined solid tumor, with its anterior edge notched in one or two places. The organ can be made more prominent by pressure with the free hand upon the left hypochondriac and lumbar regions. In less well- marked cases careful palpation, with firm pressure upon the left flank, may be required in order to bring the anterior edge forward sufiiciently to be felt through the abdominal wall. Testi heard a vascular murmur over the enlarged spleen. Examination of the blood reveals a reduction in the number of red corpuscles. Kuttner found the number in 10 cases to vary from 1,020,000 to 4,080,000, with a hgemoglobin value of 35 per cent, in the former instance and 73 per cent, in the latter. There is no absolute increase in the number of white blood- corpuscles, although in fatal cases there may be at times an increase in these elements toward the close of life. Irregular fever is frequently present, possibly owing to the frequent catar- rhal complications. In some cases epistaxis may be present, in some sub- cutaneous haemorrhages. Albuminuria seems to be rare, although Carr found it present in two of his cases. The liver is frequently enlarged, and there may be some enlargement of the deeper sets of lymphatic glands. Catarrhal inflam- mation of the bronchial mucous membrane and in the gastro-intestinal tract is frequent, but it is impossible to attribute it to the condition of splenic anaemia, owing to the frequent coexistence of the rachitic condition. Diagnosis. — When the spleen is much enlarged the history of the case and the examination of the blood render the diagnosis a matter of ease. The absence of increase of white blood-cells would diiferentiate the disease from splenic leukaemia, and an examination of the blood for the plasmodium malarige would cast out malarial enlargement. From enlargement of the spleen from amyloid infiltration the absence of a history of the influences causative of that afiection, and the failure of evidence of a similar infiltration of the liver and 25 386 A3IEBICAN TEXT-BOOK OF DISEASES OF CHILDREN. kidneys, would differentiate this disease. From an enlarged left kidney the diagnosis is to be made by the presence of notches in the anterior border, by the direction of enlargement, by the greater motility of the tumor upon biman- ual examination, and by the absence of urinary changes. The acute enlarge- ments from typhoid fever, embolic abscess, and acute malarial poisoning are readily excluded by the history of the case. Enlargement from cirrhosis of the liver would be but little apt to cause embarrassment in arriving at a diagnosis. Prognosis. — While fatal cases are not rare, the prognosis is not, as a rule, bad if proper hygienic conditions can be enforced. Of Carr's 30 cases, 10 died, 6 disappeared from sight, 13 recovered, and 1 remained stationary. The chief cause of death is the occurrence of acute respiratory or digestive inflam- matory complications. Treatment. — Of prime importance is the securing of proper hygienic sur- roundings. Plenty of fresh air, well- ventilated sleeping apartments, and a proper amount of outdoor exercise are essential. The diet must receive care- ful attention. The food should be plain and nourishing, with absence of excess of farinaceous articles. The clothing also should be regulated. Of drugs, cod-liver oil, arsenic, and iron are the most useful. Phosphorus may be used in those markedly rachitic. In cases that have a distinct history of inherited syphilis mercury may be given, but even in the manifestly syph- ilitic the splenic enlargement is apt to undergo no diminution from its use. The judicious administration of cod-liver oil by either internal means or by inunction, or by both methods combined, with the use of a combination of iron and arsenic, such as was mentioned in the section upon Secondary Anaemia, will be found to be the best line of treatment in connection with careful correction of insanitary conditions. The application of electricity over the spleen may produce lessening in the size of the organ. Lymphatic Anemia. This affection is a more or less generalized condition of the lymphoid tissue of the body, characterized by enlargement of groups of glands or increase in the normal lymphoid structures of a part, accompanied by oligo- cyth?emia and a varying amount of enlargement of the spleen. The disease bears in many respects a close resemblance to the lymphatic form of leukaemia, and, in fact, the leucocytosis that frequently is present to a marked extent has been seen to pass into a condition of true leukaemia. The whole subject of the relation between these two diseases of the l^'mphoid tissues of the body, and also between them and diffuse sarcomatous disease of the lymphatic glands, still needs further study, in spite of the work that has already been done in attempting to assign them to their proper position. Etiology. — This is still far from decided. Inherited syphilis has been supposed to play a certain role, but it is doubtful whether the association has been more than a coincidence. Age certainly exerts some influence, as the disease is very common in the young. Males are more frequently attacked than females. Heredity has not been shown to exert any influence. The action of continued local irritation or inflammation Avould seem to be a strong etiological factor, and it may be owing to the frequency of long-standing lesions of the skin, of the face and head, of the jaws and ears, that the cervical chains so frequently are the earliest and most markedly involved groups. Symptoms. — The disease begins insidiously Avith enlargement of some group of lymphatic glands, with increasing anaemia with its accompanying ANEMIA. 387 subjective symptoms, and with progressive weakness. Tlie glands most fre- quently attacked are those in the posterior cervical triangle, but the axillary or inguinal glands may be first involved. Deeper sets of glands, as those in the thoracic or abdominal cavities, may be involved before the exter- nal tumors appear, or even Avithout involvement of the superficial groups; The external glands may form large masses, producing much disfigurement. The cervical glands may obliterate the outlines of the neck or may encircle the front portion of the neck like a collar, and produce marked dyspnoea. The axillary group may be enlarged sufiiciently to prevent the apposition of the arm to the side, while the inguinal glands may enlarge sufiiciently to embarrass locomotion. Pressure of these masses may produce various secondary results, such as pain radiating down the trunks of the nerves running near to the tumors, and oedema from pressure upon the venous trunks. When the visceral sets of glands are involved, there may be no outward signs of their presence, although the retroperitoneal and mesenteric groups may be enlarged so much as to be both seen and felt. By pressure upon various organs,, blood-vessels, or ducts they may produce eff"ects varying with the part involved. Dyspnoea may be produced from pressure upon the bronchi ; cyanosis or oedema of the face from pressure upon the superior vena cava. Dyspeptic symptoms, constipa- tion, anuria, ascites, and oedema of the lower extremities may be caused by enlargement of the groups within the abdominal cavity. Secondary involve- ment of the spinal cord may produce paraplegia from pressure. The lymphoid tissue in the tonsils, tongue, pharynx, skin, and intestinal wall is occasionally the seat of the same outgrowth, producing symptoms vary- ing with the situation involved. Either continued mild pyrexia, alternating periods of pyrexia and apyrexia, or distinctly intermittent fever is usually present during some period of the course. The general symptoms are those due to the anaemia. Vertigo, headache, lassitude, and dyspnoea may be obtrusive symptoms. The patient is usually very pale, and the white skin with thickened neck forms a picture that could with difficulty fail to suggest the presence of this disease. The examination of the blood shows a decrease of the number of red blood-cells to a varying degree. Poikilocytes are common, and nucleated red blood-corpuscles are occasionally seen. There is leucocytosis, which in some cases attains to such a degree that the case must be classed as a lymphatic leukaemia. The patient usually succumbs after a period varying from less than a year to five years (Gowers) from asthenia. Obstinate diarrhoea may occur at any time, even without involvement of the intestinal canal. Death may occur from pressure upon the air-passages before the general condition of the patient would excite alarm. Morbid Anatomy. — The skin is pale, the subcutaneous layer of adipose tissue more or less decreased. The post-mortem findings vary much in dif- ferent cases in accordance with the glands involved. Usually there are masses of enlarged superficial glands in the neck, axillae, or groins. These are found to be composed either of isolated, enlarged nodules varying from the size of a pigeon's egg to that of a hen's egg, or of masses of lymphatic glands welded together or even infiltrating neighboring structures, from which they may be separated either with difficulty or not at all. Upon section the individual glands present various appearances even in the same case. They may be soft and of a color not differing much from the normal, and may yield an abundant milky juice, or they may be hard and firm, showing a clear white color of the cut surface without any juice. 388 AMEBIC AX TEXT-BOOK OF DISEASES OF CHILBBEX. Anv of the lymphatic glands in various parts of the body may be involved in the " same waV. The groups of glands in the mediastina. the bronchial glands, the retroperitoneal, or the mesenteric, may each or all of them be enlartred and more or less matted together. The thymus gland has been found either unifoinnly enlarged or the seat of lymphoid tumors. The spleen is enlarged in the great majority of cases, either from simple hypertrophy or from the presence of tumors of lymphoid tissue. The liver and kidnevs mav show nodules of lymphoid tissue. The lungs are sometimes affected from encroachment of growths from the bronchial group of glands or by the growth of independent foci of lymphoid tumors. The heart rarely shows similar growths in its substance. Various secondary morbid changes are produced by the pressure of the masses of glands upon neighboring structures. The marrow of the long bones may have a puriform appearance or may be of an intense red color. Histologically, the lymphoid tissue of the enlarged glands and of the isolated tumors is found to be composed of a delicate reticulum enclosing round cells. In some glands there is also an increase of fibrous tissue. Diagnosis. — In many cases it is impossible to state whether the case in hand shuuld be classed as one of pseudo-leuksemia or as a time lymphatic leukaemia. In the latter disease the spleen more frequently attains a con- siderable size than in the cases now classified as pseudo-leukfemia. As this disease may pass into a true leukaemia, in so far as the blood-estimation forms a criterion, and as the treatment is practically the same for the two affections, the differential diagnosis makes but little practical difference. The name •• pseudoleukiemia '■ should, however, be applied only to those cases wherein the proponion of white to red cells does not exceed one to thirty. From tubercular adenitis, the so-called scrofulous enlargement of the glands, the differential diagnosis must be based partly upon the family and past per- sonal history, partly from the appearance of the patient, but chiefly from the more localized character of the glandular swelling and the tendency to casea- tion and suppuration in the tubercular- disease. Secondary involvement of the lymphatic glands by cancer will not enter into consideration in those below adult life. Prognosis. — The outlook is extremely unfavorable. The progressive tendency of the disease may sometimes be combated by treatment, but cure can be expected but rarely. In the early stages, where the involved glands are accessible to the surgeon, the disease may be cured by operative treatment. The degree of asthenia and the extent of the anaemia offer some means of forming a prognosis as to duration. Treatment. — In early cases, where superficial glands are alone attacked, the chance of cure by surgical means should not be neglected. In cases of doubtful nature, where the diagnosis between this affection and an essentially local disease of the affected glands is difficult, the safest course is to avail ourselves of surgical means of cure. Of drugs, arsenic is the only one upon which dependence can be placed. It should be administered in ascending doses until the point of tolerance is reached. Iron is of secondary value as a htematonic, but may be combined with arsenic, preferably in the form of the officinal syrup of the iodide of iron. External applications to the affected glands can only be of value where the integrity of the skin is in danger. Tracheotomy may be necessitated by pressure upon the trachea or if the enlarged glands interfere with the nerve-supply of the vocal cords. LEUKAEMIA. 389 LEUKAEMIA. Leukemia is a disease of the blood-making organs, characterized, clin- ically, by the symptoms of angemia, excessive increase in the number of white blood-cells, and a tendency to hjemorrhagic extravasation ; pathologically, by enlargement of the spleen and lymphatic glands and by changes in the bone- marrow, either separately or in combination. The condition of the blood in this disease is mimicked in health after eat- ing (physiological leucocytosis) and in various organic diseases wherein there is an intense local lesion (pathological leucocytosis), as in pneumonia, empyema, etc. The term "leuksemia," however, must be limited to cases wherein leuco- cytosis is more or less constant, is of marked degree, and is associated with the characteristic lesions of spleen, lymph-glands, or bone-marrow. As to the nature of the disease there is much diversity of opinion. The term "leukaemia" is at present the most applicable, because non-committal, name that Ave can apply to it. Various divisions have been made in respect to the part chiefly or solely involved in the disease — splenic, lymphatic, or medullary (myelogenous). Rarely is any one form present alone, but the cases usually fall into the classes lieno-medullary or lieno-lymphatic. Cutaneous, intestinal, and tonsillar forms are curiosities. The disease bears, in many respects, a close resemblance to sarcomatosis. Etiology. — The precise etiology of the disease has not yet been decided. It is preceded by malaria and syphilis in a number of cases sufficient to render it possible that these diseases have at least a predisposing influence. Trauma in the splenic region has been followed by its appearance. Some of the more acute cases pursue a course that is strongly suggestive of an infectious origin. Fermi, Powlowski, Bonardi, Kelsch and Vaillard, Klebs, E.oux, and others have reported the finding of various micro-organisms in the blood or tissues of cases of the disease. Negative results were reached in Westphal's case in an attempt to obtain cultures from the spleen during life and from the blood and bone-marrow after death. Gilbert unsuccessfully attempted to inoculate healthy dogs with lymphatic glands from a dog aff'ected with the disease. Hosier failed to produce the disease by the injection of leuksemic blood into dogs and rabbits. Bollinger met with a similar result in attempting to pro- duce the disease in healthy animals by the injection of blood from leukgemic animals of the same species. Apparent infection occurred in Obrastzow's experience, where an attendant upon a case died after fourteen days' illness with purpura, haemorrhages, fever, albuminuria, and a proportion, in the blood, of one white to nine red blood-cells. The disease is seen at all ages from birth up to the seventy-fifth year. It is most frequent between the ages of thirty and fifty years. It is not rare in childhood, many cases having been reported in infants less than two years of age, while Sanger has reported its existence in a stillborn child. It is more common in males than in females. Heredity has not been proven to be an etiological factor. Horses, oxen, dogs, pigs, cats, and mice sufier from a sim- ilar affection. Symptoms. — The usual symptoms that impel the patient to seek advice are the general weakness, the pallor, the shortness of breath, haemorrhages from the mucous membranes, the enlargement of the abdomen, or the super- ficial lymphatic tumors. The disease usually arises gradually, so that, as a rule, marked changes in the organs and blood have occurred before the patient is brought for treatment. 390 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. The symptoms produced by the abnormal condition of the blood are similar in the different forms of the disease, but the examination of the patient yields results varying with the type. Breathlessness upon exertion is usually a very marked feature. It may' be accompanied by marked vertigo upon change of posture. The bodily strength is impaired to a great degree, but in some cases it is remarkably well preserved in view of the serious changes in the composi- tion of the blood. Haemorrhages may have occurred from the nose, throat, stomach, or intestines, or there may be hsemorrhagic extravasations beneath the skin. Haemorrhages in the fundus oculi may produce sufficient interfer- ence with vision to attract the attention of the patient. Edes has recorded a case wherein priapism was the first symptom. During the course of the disease occasional rises of temperature may be noted. Upon examination there is found more or less pallor of skin and mucous membranes. The pulse is soft and compressible, with increased rate. If the anaemia be marked, there may be heard a hgemic murmur over the position of the apex-beat or in the second left intercostal space. The lungs usually present no morbid signs save toward the close of fiital cases, when oedema, congestion, or a fluid accumulation in the pleural cavity may be found. In some cases there is found in the lung what clinically resembles lobar pneu- monia, but histologically is found to present features differing from the ordinary form. Diarrhoea may be persistent, and in some cases a species of dysentery is present. Vomiting is not a frequent symptom. The occasional occurrence of hoematemesis has been mentioned above. The urine is usually unaltered save for an increase in the amount of uric acid excreted. On the part of the nervous system we may have no symptoms. Vertigo and cephalalgia are at times marked. Death may occur from intracranial hjemorrhage. Vision may be much impaired, due to the presence, as revealed by the ophthalmoscope, of retinal htemorrhages or of leukaemic deposits. Hearing may be impaired. Suchamick has noted a peculiar brownish discolora- tion of the nasal mucous membrane in one case. The usual course of the disease is slowly progressive, covering a period of months or years. There have been reported some cases running an extremely rapid course, as in that of Guttmann, where a fatal termination occurred after an illness of four and a half days. The examination of the blood is all-important in determining the nature of the disease. The constant feature is an increase, both relative and absolute, of the white corpuscles. This may attain to an extreme degree, the relative number of white to red cells having even been as two to one in a case reported by Robin. The average ratio of Avhite to red cells is as one to fifty or twenty, in cases without great reduction in the latter elements, as opposed to one to 500 or 700, the average ratio of health. The various forms of white blood-cells are present in different proportions in the lieno-medullary and in the lymphatic varieties. In the former the eosinophilous cells of Ehrlich are the predominent form, whereas in the acute lymphatic variety the lymphocytes form the main proportion of the colorless elements. Where the lymphatic, splenic, and medullary varieties exist together in the same patient, the propor- tion of the forms of leucocytes will produce variations from the two types mentioned. ^lyelocytes may l^e present in large numbers. Charcot's crystals are said to form after the blood has remained upon the slide for a short time. In the splenic form a prominent feature is the gradual enlargement of the spleen. This occurs to a varying degree, the organ in extreme cases even LEUKEMIA. 391 reaching to or beyond the median line of the abdomen. The splenic enlarge- ment takes place chiefly in a diagonal direction, downward and toward the right. When the hand is placed over the mass, a rub may be felt and tender- ness be elicited by pressure. Spontaneous pain or sense of pressure may be an annoying symptom, while the weight of the organ may produce dis- order of digestion or marked constipation. When the marrow of the bones is affected, there may be tenderness over the affected parts, with localized swellings on the shafts of the long bones or the ribs or sternum. The lymphatic glands are less frequently involved than is the spleen. The superficial glands show enlargement and can be readily felt, or even seen as isolated groups or chains. The deep glands of the abdominal cavity may be affected. Morbid Anatomy. — The skin is pale, the subcutaneous fat usually much diminished. The blood has a chocolate color, or may even almost resemble sanious pus. When clotted it has a greenish-yellow color. On the serous membranes there may be areas of hiemorrhagic extravasation. In the serous cavities there is usually an excess of fluid. The heart is frequently found distended with clotted blood. The lungs present no constant changes, although posterior congestion is often seen. Rarely are there any qhanges in the thymus gland. The spleen is almost invariably enlarged to a greater or less degree. Adhesion to neighboring organs is common, explaining the sharp attacks of pain sometimes experienced in the left hypochondriac region. The organ is usually symmetrically enlarged, is of increased density, and on section may show either a brownish color throughout the surface, or there may be scattered areas of a white color due to localized infiltration with lymphoid cells, either in the Malpighian follicles or in the pulp. Hemorrhagic areas may be present. The spleen may enlarge so rapidly as to cause a rupture of its capsule. The intestines show at times evidences of lymphoid infiltration, either in the glands of Peyer or in other parts, by thickening without ulceration. The tonsils, pharynx, and stomach have been found to show signs of the over- growth of lymphoid tissue. Lymphoid tumors have been found in the liver in sufficient number to notably increase the size of the organ, while the kidneys also may present whitish areas of lymphoid infiltration, as in the case reported by Frankel. The lymphatic glands of the superficial sets or of deeper parts, as near the root of the mesentery, are in some cases much enlarged, although rarely to so great an extent as in pseudo-leuksemia. The marrow of the bones is afiected in a considerable number of cases, chiefly in conjunction with splenic involvement. In these cases it is found to be of a puriform appearance or to be of a dark-red color. H^emorrhagic areas may be present. The shaft may be found expanded and the wall thinned. Microscopically, the marrow shows large numbers of nucleated red blood-cells, eosinophiles, and myelocytes. Diagnosis. — The only diseases with which leukaemia is apt to be con- founded are pseudo-leukgemia, splenic anaemia, and scrofulosis. From these the diagnosis may readily be made by an examination of the blood. The numerical increase of the white blood-cells is alone sufficient to make the dia- gnosis, save in cases of non-leukamic leucocytosis. From this the diagnosis cannot be made with certainty by the haemocytometer alone, as in leucocytosis the relative increase of white cells may be greater than in some cases of leukaemia. For the difi'erentiation of these two conditions we may employ the 392 A3fERICAN TEXT-BOOK OF DISEASES OF CHILDREN. method of diiferential staining according to Ehrlich's procedure. While some question has been raised as to the value of the eosinophile cells as diagnostic criteria, this objection cannot now be said to be of weight save in the lym- phatic variety, where the cells having eosinophile granules are not present in large number. Prognosis. — The prognosis as to recovery is grave, although cases have been known to recover. The disease is usually fatal within a few j^ears. In some cases of acute lymphatic leukaemia, as in the case reported by Guttmann, death may occur within a few weeks or days. Treatment. — Rest is of prime importance. The dietary should be selected with care, and should be suited to the digestive power of the individual. Arsenic is almost the only drug that can be said to be of any real value. It should be pushed up to the verge of tolerance, and its use should be per- sisted in until either it is evident that no result is being obtained or until the patient is, mayhap, relieved of the disease. Quinine should be tried in cases giving a malarial history, but it will rarely be productive of much benefit. Injections of arsenic into the spleen are not likely to materially benefit the patient, and are not without risk. Westphal's case died after a puncture of the spleen for diagnostic purposes, the organ being surrounded by a large blood- clot at the autopsy. Splenectomy cannot be considered justifiable, in spite of Franzolini's successful case, in view of the large mortality attending the operation. HAEMOPHILIA. By WILLIAM PERRY NORTHRUP, M. D., New York. HEMOPHILIA is a tendency to obstinate bleeding ; inherited ; often asso- ciated with swelling of the joints. Etiology. — The haemorrhages may be traumatic or spontaneous in origin. Certain families are known as " bleeders," the hsemorrhagic diathesis manifest- ing itself at any time from early infancy to the end of life. Hereditary trans- mission takes place mostly through the mother and to her male offspring. If a woman descended from bleeders marry a healthy man, the sons will inherit the hsemorrhagic diathesis, the daughters escaping. In the succeeding generations the sons in whom haemophilia is manifest will not transmit the diathesis, whereas the daughters, who show in themselves no signs of it, will transmit the diathesis again to their sons. The maternal transmission so continues to many generations, the hsemorrhagic condition appearing in the males, the females escaping, but transmitting the diathesis to their sons. Bleeders usually have large families, some of whom may escape the disease. They are to be found in all localities, in all conditions of life ; are healthy in appearance, commonly having fine, soft skins. The HebreAv race is said to be particularly liable to it. The real cause of haemophilia is unknown. It is believed that the condi- tion has in some individual instances been acquired. Pathological Anatomy. — The post-mortem findings do not explain the nature of the affection . An unusual thinness of the walls of the vessels has been observed, though the microscope fails to reveal any essential and constant alterations. The tissues are blanched from loss of blood. Petechiae and bruised patches are frequently observed upon the surface of the body. The swelling of the joints is due to haemorrhages into the articulations and the surrounding tissues. Occasionally there is evidence of joint inflammation. At present it has not been determined whether the haemorrhage is due to some fault in the walls of the vessels, or whether there is some peculiarity in the character of the blood on account of which thrombi are not formed. Syraptoms. — At birth there is nothing in the appearance of the child to indicate the peculiarity of his inheritance. He is usually healthy and bright, and may in the first year develop no signs of haemophilia. The severing of the umbilical cord does not usually give occasion for obstinate bleeding, and not until his growth and strength lead him into accidents, such as bruises, cuts, scratches, and punctures, does the haemorrhagic tendency become apparent. Epistaxis is the most common experience which calls attention to the diathesis. This may be acute, obstinate, and alarming. Besides, there may be petechiae, ecchymoses, haematomata, interstitial and external bleeding, traumatic or spon- taneous. A common symptom is swelling of the joints closely resembling rheumatism. It is not uncommon to find haemorrhage of the gums at the eruption of the second crop of teeth. Slight cuts give rise to troublesome haemorrhage, slight 393 394 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. blows to marked ecchyuioses, and a blister may contain blood instead of serum. Prolonged and dangerous bleedings may follow the extraction of a tooth in spite of the application of the strongest styptics. The bleeding is from the capillaries, most often an oozing, which may con- tinue from hours to weeks. The subjects of Imemophilia are very sensitive to cold, and suffer from joint-pains apart from those dependent upon haemorrhage. Such patients pass througli the exanthemata and other diseases of childhood without special dangers, and have no marked proneness to phthisis. Sloughing and gangrene are not uncommon accidents of this condition. Prog-nosis. — From the nature of the disease it must be considered a con- stant menace to life. However mild the tendency in the infant, the prognosis should be considered very serious. Of 152 cases of haemophilia traced by Grandidier, more than half died before completing the seventh year, and only 19 attained majority. The exhaustion of repeated haemorrhages, or. more commonly, the draining away of blood by continued oozing, may destroy life. The most difficult of control and the most frequently fatal are the haemorrhages following extraction of teeth or from epistaxis. There are examples of bleeders who have attained a good age and led busy lives. To this class belongs a very busy practitioner of the writers acquaint- ance, who is never without fresh petechiae of the face, and constantly carries a large red handkerchief for accidental epistaxis. In females the prognosis is good, neither menstruation nor childbearing being complicated by this capricious example of atavism. Treatment. — Prophylaxis avails somewhat to diminish the accidents of haemorrhage. The system may be fortified by abundant fresh air and tonics, by judicious exercise and general hygiene. The child should be guarded, so far as possible, from bruises, cuts, and punctures. Vaccination, though not historically accounted a dangerous procedure in bleeders, should be accom- plished rather by scarification than by incision. Slight operations should be seriously considered before they are undertaken, and every needed means of htiemostasis should be at hand. The extraction of teeth should be avoided. Nearly every practitioner has had at least one trying experience with obstinate haemorrhage from such cause in a person not haemophilic, and can well under- stand the importance of this advice. It is well to have the diet properly regulated for hsemophilics, giving vege- tables and generally wholesome mixed meals, without excess of meat. The bowels should be regulated so as to correct any tendency to a "full-blooded " condition. Where premonitory symptoms indicate an impending haemorrhage, it is well to relieve the bowels by a mercurial purge, followed by a saline. In case of haemorrhage treatment will necessarily be modified by the region in which it takes place. Cuts and bruises should be cleansed and" bound up, with ice, perchloride of iron, or nitrate of silver applied to the point of bleed- ing. In epistaxis the nasal cavities may be treated by irrigating the parts with cold water or by an absorbent-cotton plug saturated with peroxide of hydrogen ; if need be, the cavities may be tightly plugged with cotton soaked in an iron solution. If the haemorrhage arise from the socket of an extracted tooth, applv crystals of subsulphate of iron or a cotton pledget soaked in Monsel's solution, or apply caustics. Haemorrhages from the bowel should be treated with opium to secure quiet and rest, and by cold-water injections. Hemophilics should be dressed warmly, should avoid cold, damp climates, and all so-called rheumatic surroundings. ' The joint affections may be treated much like similar conditions in chronic rheumatism, perfect rest and soothing applications being primarily indicated. PURPURA HEMORRHAGICA, By GEORGE ROE LOCKWOOD, M. D., New York. Under the term " Purpura Hsemorrhagica " -we include a clinical group of cases characterized by the association of purpura with hgemorrhages from any of the mucous membranes, less frequently into serous membranes and joints or into the substance of the viscera. First described by "Werlhof in 1775, it is often known as "Werlhof's disease." It is also known as "morbus macu- losus." A careful study, however, of the cases embraced by this definition shows such a variety in their clinical course and in their etiological factors that it seems impossible to regard them even as different types of the same disease. Their symptoms, in a general way, may be alike, but in some cases they appear suddenly and peracutely without assignable cause, associated with symptoms of acute sepsis, often causing death within a few hours or days. In other cases without known cause the symptoms appear subacutely, and are less marked, the constitutional symptoms being mildly septic in character. In still others the symptoms occur either as a complication of some coexisting disease or as the result of a well-known cause. It seems better, therefore, to regard the term purpura hsemorrhagica as one purely clinical in its scope, including a number of cases, distinct in their clinical course, pathology, and etiology, but which present, in common, symptoms of sufiicient similarity to be included under one general name. The study, then, of purpura hgemorrhagica is rendered more clear by dividing the cases of this disease into two groups : I. essential, and II. symjJtomatic pur- ipura hcemorrJiagica ; the esseyitial group including those cases in which the disease begins without known cause, the haemorrhages and purpura being asso- ciated with more or less marked septic symptoms, and running a course resembling that of an infectious disease ; the symptomatic group including those cases in which the symptoms arise from a well-known cause (as poisoning from over-use of potassium iodide), or as a complication of a severe blood or infectious disease (as in profound anaemia or in the exanthemata). The essential cases seem to the author to constitute the only true group to which the term purpura hgemorrhagica should be rightly applied, and th«se will therefore be described more fully than the symptomatic cases, which should more properly be classed among the symptoms of the diseases which they complicate. I. Essential Purpura Hemorrhagica. This form occurs both subacutely and acutely, the former being far the more common, and about which we know most. 395 396 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Subacute Purpura Hemorrhagica. This variety of the disease is seen more frequently in females than in males. "While no age is exempt, it usually attacks children and young adults. Food deficient in quantity and quality, poor hygiene, and a Aveak, sickly constitution predispose to the disease, but not as markedly so as in scurvy. Often it attacks those who are healthy, well fed, and -well housed. There is rarelv a family history of any hjemorrhagic disease, although in two cases in vount' rrirls under the author's observation the father of each had been subject to severe attacks of epistaxis in early life. The subacute cases occur in two clinical forms : (1) ordinary cases, and (2) eases of HenoeK's disease. Ordinary Subacute Cases. — This form usually begins with prodromal symptoms, anorexia, malaise, chilly feeling, and irregular rise in temperature, especially at night. These may precede the onset by several days or even weeks. In other cases there is no prodromal period. When the disease is fairly develojied we have both htemorrhagic and constitutional symptoms. Symptoms. — Hfemorrhagic Symptoms. — There appear purpuric spots, usually first noticed on the extremities, though they may be generally dis- tributed. Their size varies from that of a pinhead to that of the palm of the hand. In severe cases Ave ma}' have large areas of ecchymoses, which may be extensive enough to cause gangrene of the skin. Successive crops of purpura appear during the disease, and they may be often produced by rubbing or scratching the skin. Rarely we have associated with the purpura and ecchy- moses hfemorrhagic vesicles and bullae. There are free htemorrhages from any of the mucous membranes — nose, mouth, gums, bronchi, stomach, intestines, and jselvis of the kidney. There may be also metrorrhagia. The most frequent sources of haemorrhage are from the nose, pelvis of the kidney, intestines, and uterus respectively. These haemorrhages occur spontaneously, and not from traumatism alone, as is the case in haemophilia. They may be moderate in their severity or profuse enough to cause the death of the patient. Pain and SAvelling of the joints, especially those of the hands, feet and knees, are frequently noticed. The symptoms are identical with those of pur- pura rheumatica. There may be sAvelling of the fibro-serous tissues about the joint, or the joint-cavity may be filled by an effusion either serous or fibrino- serous. In severe cases the joint may become ankylosed or an arthritis may be caused. The primary symptoms are due to haemorrhages either into or around the joints. Internal haemorrhage may occur at any time and into the substance of any of the viscera, especially the brain and its membranes, the suprarenal capsules, or the lung. These internal haemorrhages, hoAvever, are rare in the subacute form, though more common in acute cases. The gums may be normal or swollen, although this is denied by many writers. They may be covered by blackish scabs, and may bleed even when they are not swollen. The teeth, hoAvever, are not loosened as in scurvy. In no case are ulcers of the intestine, due to submucous haemorrhages, ever seen. Free haemorrhage from the skin does not occur. Although the kidneys are frequently the source of haemorrhage, nephritis has not been observed. Constitutional Symptoms. — These appear in varying intensity, and are due both to the anaemia from the haemorrhage and also to moderate sepsis. A dis- tinct chill at the onset is rare, but chilly feelings are common and may continue through the attack. The temperature varies from 100° to 103°, or even 104°, being higher in severe cases and in children. It is higher at night. After the PURPURA HEMORRHAGICA. 397 severity of the attack is over the temperature gradually returns to normal : a sudden fall in temperature, with a subsequent rapid rise, is noted in cases of sudden severe haemorrhage, especially if such occur into the viscera. The pulse is of low tension and somewhat rapid. It may become rapid, small, and weak. Attacks of syncope are common. General anaemic symptoms are always present, even in cases in which the haemorrhages are slight, but they are more severe when the haemorrhages are profuse. They appear early in the attack and continue throughout its dura- tion ; after the attack subsides the recovery is long and tedious, and often it takes weeks or months before the blood returns to its normal condition. Examination of the blood during the attack shows rapid diminution pf the number of red blood-corpuscles, and a corresponding diminution in the amount of haemoglobin. The white cells are at first increased in number, as is the case after acute haemorrhage, but later their number steadily diminishes, even during early convalescence, while the number of red corpuscles and the amount of haemoglobin are steadily increasing. These points are well shown by the records of blood-examinations made in a case reported by Osier : Number of red cells. Number of white cells. Per cent, of haemoglobin. 1st day, 5,350,000(107%) 8,000 95 2d day, 3,000,000(60%) 12,500 50 8th day, 2,500,000 (50%) 12,500 37 14th day, 3,000,000(60%) 7,000 47 50th day, 4,000,000(80%) 2,500 62 70th day, 4,250,000 (82|%) 72 Prostration is a prominent symptom, and is always more marked than can be accounted for by the haemorrhage and constitutional symptoms. It remains usually for some weeks after all other symptoms have disappeared. In severe or long-continued cases it may be so profound that the patient passes into the " typhoidal condition," with rapid and feeble pulse, dry brown tongue, stupor alternating with mild delirium, or even coma and death. The spleen and liver are usually enlarged during the attack. The enlarge- ment of the liver in some cases is well marked, and may be distinctly appre- ciable for weeks or months after the subsidence of the disease. The conges- tion and enlargement of the liver often cause a mild catarrhal jaundice, which, added to the anaemic appearance of the patient, gives a bright fawn-yellow color to the skin. The duration of the attack varies from a few days to several Aveeks, but the disease may be protracted for weeks, months, or years by the appearance of similar attacks (or "relapses" of some authors). These attacks may recur at regular or irregular intervals, their usual nunjber being four or five. In one unique case under the author's observation the attacks have persisted for fifteen years, the patient showing no signs of improvement at the end of this time. The next case of longest duration is one reported by Hryntschak, in which the attacks lasted for seven years. Nature and Pathology. — For the blood to escape from its vessels and cause haemorrhage we must naturally conclude that the vessel-wall must first rupture. As this does not normally occur, except from traumatism, we must also conclude that its wall is weakened either from inflammation or from degeneration due to disease, to poor blood-supply, to toxic blood, or to thrombi. Much light has been thrown on this subject by Silberman, who gave fifteen 398 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. dogs small steady doses of pyrogallic acid until there appeared areas of stasis in the small arteries, capillaries, and veins. After pressing out the stasis-blood he injected fibrin ferment into the arteries. The dogs had abdominal tender- ness, purpura, bloody vomiting, and bloody stools. Autopsy showed in the hemorrhagic areas thrombi in the small arteries and veins, whose walls had undergone liyaliiie degeneration with areas of necrosis, thus allowing the free escape of blood. Many attempts have been made to discover a specific bacterium, but before the time of Letzerich the examinations were so incomplete as to be entirely without value. Letzerich, however, in 1889 made scientific bacterial exam- inations, and discovered a bacillus which he believes to be the specific germ of the disease. Although his experiments have not been corroborated by others, their success still remains of the greatest value. His patient Avas a girl suff'er- ing from the subacute form. Bacterial examinations, scientifically performed in every detail, showed in the purpuric spots the presence of long bacilli capable of groAvth in gelatin, the pure cultures of which, injected into the abdomen of rabbits, reproduced the original clinical symptoms in all of the twelve cases, and in these a bacillus was found identical with that in the pure culture injected. An examination of the purpuric spots in the rabbits showed dilatation of the capillaries, emigration of white cells, and rupture of the capil- lary wall, permitting the escape of red cells. The capillaries were filled Avith the bacilli with abundant spore-groAvth. (The bacilli and spores had been previously described by Petrone, in his examinations of a case of Werlhof 's disease, but he considered the disease to be due to a mixed infection.) Upon squeezing the section Letzerich found that little plugs resembling hyaline casts containing bacilli emerged from the capillaries, and these he con- sidered the result of the action of the bacillus in its products upon the fibrino- plastic elements of the blood. The liver in the rabbits was regularly enlarged, and the portal capillaries were almost occluded by an extraordinary growth of the bacilli. Letzerich considers the liver to be the breeding-place of the bacilli, the liver being to this disease what the spleen is to malarial fever. If he be correct in his conclusions, it explains both the scattering of the lesions — a bacterial embolism of the capillaries causing hyaline thrombi within them Avith rupture of the capillary Avail — and also the tendency of the disease to relapse. While conducting his experiments Letzerich was himself seriously attacked by this disease, attributing his infection to handling his cigar Avhile at Avork. This case of infection seems to prove the advisability of disinfection after an attack. Prognosis. — This is generally good, almost all patients recovering from the primary and secondary attacks. Recovery, however, is sloAV, the ansemia and prostration often lasting for months after the disappearance of other symp- toms. The occurrence of the sepondary attacks cannot be foretold. In rarer cases the disease terminates fatally, the cause of death being either profound anaemia, fatty degeneration of the heart, with or Avithout dilatation, from long- continued an;iemia, visceral haemorrhages, or exhaustion. Treatment.— This is unsatisfactory, both in shortening and mitio;atino; the attack and in the prevention of subsequent relapses, as there is no specific knoAvn that acts in this disease as quinine does in malarial fever. Our treat- ment, then, must be entirely symptomatic, and consists in treatment during the attack and prophylactic treatment destined to prevent future attacks. The treatment during the attack consists in efforts to check the haemor- rhage and in the relief of constitutional symptoms. To check the haemor- rhages no one drug is certain. We employ, in turn, a number, until we find PUBPUBA Hu^MOBBHAGICA. 399 one that is efficacious, but we may run through the entire list of haemosta- tics without result. The drugs which are most frequently used are aromatic sulphuric acid, ergot, turpentine, digitalis, quinine, and gallic acid. During a haemorrhage the patient must be kept absolutely quiet, even if morphine be required for this purpose. In all cases and at all times care should be taken to guard against traumatism, over-exertion, and excitement. Alcohol and highly-seasoned food may also give rise to a haemorrhage. Epistaxis may be checked by astringent sprays or by plugging the nares. Uterine haemorrhage should be treated by firm tamponage. If the joints be affected, salicylic acid is often of service. The pain may be relieved by anodyne applications, as lead-and-opium wash, ichthyol or iodine ointment, or by the application of heat and cold. Firm compression is often grateful. Constitutional symptoms are treated on general principles. The patient must be put to bed and on a low diet during the attack. Later he may be about the loom, and a more generous diet may be allowed, vegetables and vege- table acids and fruit being especially indicated. In all cases the patient should be kept quiet and free from excitement or exertion. The bowels must be kept open, and any digestive errors corrected. Should the pulse become rapid and feeble, cardiac stimulants are indicated, especially digitalis and strychnine. Alcohol in large doses should not be used. During the close of the attack tonics are to be given, quinine, strychnine, and arsenic being the best combination. Iron is contraindicated, as, by experi- ence, we know that its early administration may bring on a fresh attack. If the anaemia be marked during the attack, arsenic is the drug most efficient. It is to be given in increasing doses to the point of tolerance, then stopping its use for a day or so, and then increasing its dose as before. If symptoms of sudden profound anaemia occur, we apply warmth to the body, hot applications over the heart, and give cardiac tonics, especially opium in small, repeated doses. Inhalation of pure oxygen gas is of the greatest service. In severe cases we employ, in addition, rectal or hypodermatic injec- tions of a warm sterilized saline solution. Several pints can be given in this way with great improvement of the symptoms, although this may be but tem- porary. Arterial transfusion is not to be used, because of the danger of trau- matic haemorrhage. Elevation of the foot of the bed and ligatures applied to the extremities are often followed by good results. The prophylactic treatment employed during and after convalescence is intended to lessen the chances of subsequent attacks. The patient must live and work in airy, sunny rooms and take graded exercise in the open air, for fresh air and moderate exercise are of the first importance. The plumbing must be in perfect sanitary condition. The diet should be wholesome and varied, and every digestive error corrected. For the anaemia, arsenic in small continued doses is by far the best treat- ment. It should be continued until the blood becomes normal. It may be combined with quinine and strychnine. Iron is not to be used at first, but several weeks after the primary attack has subsided it should be given in small doses at first, then slowly increasing. Should a relapse threaten, the iron must at once be stopped. Prostration is to be treated on general principles by rest, fresh air, graded exercise, and change of climate. The climate most suitable is one in which the air is light, dry, and bracing ; and the location must be inland, as we find that the disease more extensively prevails on the sea-coast. As the disease is probably due to an infectious specific germ, and as the sub- 400 AMEBICAX TEXT-BOOK OF DISEASES OF CHILDREN. sequent attacks are also probably due to reinfection, it seems certainly better to disinfect the room and tiie clothes of the patient after the illness. The more we study this disease, the more we incline toward such disinfection. Henoch's Disease. — The severe form of the subacute cases was first described by Henoch, and is known as "Henoch's disease" or " Henoch's purpura hjemorrhagica." This form occurs with greater frequency in children, especially between The ninth and twelfth years. It has been observed, however, between'the third and forty-sixth years. It occurs five times more frequently in males than in females, 'it is a rather rare form. Symptoms. — There is usually a short prodromal period with malaise, slight fever, and sometimes with pains in the joints. The onset is manifested by the appearance of purpura, in severe cases accompanied by ecchymoses, these differing in no way from those described under the first form. Immediately after the purpura, appear the severe abdomi- nal symptoms which characterize'the disease. There is marked pain and ten- derness over the abdomen, the pain being of a colicky character, with exacer- bations of great intensity. The abdomen is rigid and retracted. There is severe rectal tenesmus with bloody stools and severe vomiting, the vomited matter being either like that of acute gastritis or containing blood. These abdom- inal symptoms seem to be due to submucous hemorrhages or to hjemorrhagic infiirctions caused by thrombi in the small blood-vessels of the gastro-intestinal wall, which become degenerated and rupture, allowing free hpemorrhage. Patches of intestinal ulceration result in rare cases, and rupture into the peri- toneal cavity with fatal peritonitis may occur even after apparent recovery. These symptoms continue with great intensity for one or two days, and then gradually subside. They may continue longer, but in such cases there are periods of temporary improvement. Joint symptoms may appear as in the first form. Htematuria is seen in one-fifth of the cases. The spleen is usually enlarged, and there is a slight rise of temperature during the attack. After such an attack the patient is liable to have a series of similar ones, usually at short intervals. There are generally four or five such, but their number has been recorded as high as twenty. The nature of the disease is unknown. No specific micro-organism has as yet been found, but as the reported cases are few, it is possible that in time one will be discovered, either Letzerichs bacillus or some other bacterium pro- ducing the same results. The duration varies according to the length of the attacks, their number, and the intervals between them. It is usually six to twelve weeks, but may be limited to a week or be extended to nine months. ProgTiosis. — This is fairly good, being better in children (moi'tality, 5 per cent.) than in adults (mortality, 25 per cent.). The possibility of intestinal rupture and peritonitis, though rare, must be taken into account. Treatment during an attack is purely symptomatic. Between the attacks we improve the general condition in every way. Acute Purpura Hemorrhagica is far more rare than the subacute form. The same symptoms are present, but run an acute and more severe course, overwhelming the patient by their violence and the rapidity of their onset. The acute form diifers, moreover, from the subacute in the severity of septic symptoms, in the frequency of visceral haemorrhages, and its disposition to attack pregnant women. We can PURPURA HEMORRHAGICA. 401 broadly subdivide the acute cases into three groups : (1) cases with marked sepsis ; (2) cases with visceral haemorrhages ; (3) cases complicating preg- nancy. 1. Cases with marked Sepsis. — These present both severe hsemorrhagic and septic symptoms, but the latter are so predominant that the course of the disease is essentially that of acute septicgemia. The attack usually begins by a chill or chilly feelings, with a rise in tem- perature to 103° or 104° F. Hsemorrhagic symptoms soon develop, purpura and haemorrhages from any of the mucous membranes. These are severe, and are not readily controlled by treatment. Septic symptoms are marked from the onset — severe prostration, mental apathy, stupor, or semi-coma, alternating with periods of restlessness, anxiety, and mild delirium, and finally, in fatal cases, complete coma. The temperature remains high, 103° to 104°, but in severe cases it may rise to 105° or 106°. The pulse becomes rapid, feeble, and irregular ; and the patient usually dies early in the disease, either from sepsis or from acute anaemia. The following case, personally observed, illustrates most typically the clin- ical course of this form : L. M , female, nineteen years, had always lived in most affluent circumstances ; had never been sick except from slight anaemia for the past two years. Father when a boy would bleed severely from slight causes. No further haemophilic history. March 7th, 1 A. i\i., slight chill without rise in temperature. Very nervous and anxious. 12.45 P. M., marked chill, fever rising to 103.5°, and epistaxis becoming more and more profuse in spite of every effort to check it. March 8th, 1 p. M., first seen by author. T. 98.4°; P. 130, irregular and weak; marked pallor of skin; prostration profound; complete mental apathy, though her mind was clear when she was aroused. New purpuric spots appearing. Gums normal. No evidence of endocarditis nor of any other appreciable disease. Spleen enlarged ; epis- taxis still continuing, the blood being dark and not coagulating. Profuse uterine haemor- rhage. Haemorrhages were checked by plugging posterior and anterior nares with cotton dipped in collodion and by firm tamponing. 8 P. M., T. 102.8° ; P. 130-180, weak and irregular ; semi-coma, alternating with periods of restlessness and mild delirium. Still slight hsemorrhages from nose and uterus in spite of former treatment. 10 P. M., about a pint of warm sterilized saline solution was given by rectum and by hypodermatic injections, with slight but temporary improvement. Cardiac tonics, whiskey, and digit- alis were freely administered. March 9fh, 9 A. m., T. 104.8° ; P. 148 ; R. 32. Large ofi'ensive tarry stool of altered blood. Injection of saline solution continued. 6 P. M., complete coma. T. 106.2° ; pulse weaker and flickering. Blarch 10th, 2 a. m., she died, two and a half days after the onset of the disease. No autopsy was permitted, and bacterial examinations could not then be made. Etiology. — There is no known cause for this disease. It occurs more fre- quently in men than in women. The average age of the males affected is twenty-eight years ; of the females, twelve years. It has been observed, how- ever, between one and seventy years of age. The average duration of the attack is about one week, although it may last from one to twenty days. Prognosis. — The prognosis is bad, 75 per cent, of the cases terminating fatally. Treatment consists in — (1) checking the haemorrhages by plugging the nares, by firm tamponage, or by the use of haemostatics, as described in the sub- acute form. (2) In controlling the sepsis. This is often more than we can do, although in some cases alcohol in large doses seems to do good. (3) In the treatment of dangerous symptoms. Heart-failure is to be treated by hot appli- cations over the precordium and by cardiac stimulants. The restlessness and anxiety are best controlled by opium given in small doses. Profound anaemia 26 402 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. is to be treated by external warmth, rectal and hypodermatic injections of a warm sterilized saline solution, elevation of foot of the bed, and ligatures applied to the extremities. Arterial transfusion is contraindicated. 2. Cases with Visceral Hemorrhage. — In these cases the brain and the suprarenal capsules are the organs most frequently involved. In the brain cases the disease begins with the ordinary symptoms of acute purpura haemorrhagica. After several days these are followed by those of meningeal or cerebral hjemorrhage, usually multiple, and without any especial seat of selection. It is seen far more frequently in males than in females. Illustrative Cases : 1. Girl, aged two years. For two days diarrhoea and vomiting ; then purpura, fever, and collapse. Death in a few hours from multiple haemorrhages into the medulla. (Zuelchauer, Bo'l. klin. Wochensch., 1869, No. 17.) 2. Young man. General acute symptoms. Death on fourth day from haemorrhages into left Sylvian fossa, pons, and ventricles. (Kurkowski, V. und H. Jahresherieht, 1885, ii. p. 493.) In cases of haemorrhage into the adrenals the course of the disease is exceed- ingly acute, and death results in a few hours after the onset. Illustrative Cases : 1. Soldier, aged twenty-two. Purpura; haemorrhage from mouth, lungs, and kidneys. Death in seven hours from adrenal haemorrhage. (Bourrieff, V. und H. Jahresber., 1878, ii. p. 275.) 2. Male, aged two years and nine months. Purpui'a, fever, and collapse. Death in fifteen hours from adrenal haemorrhage. (Wolff, Berl. klin. Wochenseh., 1879, No. 18.) 3. Cases Complicating Pregnancy. — In the cases in which the disease attacks pregnant women we have the ordinary acute symptoms at first, fol- lowed by miscarriage and post-partum haemorrhage. It may also follow labor at term. The disease runs a rapid course, and recovery is rare. Illustrative Cases : 1. Female, aged twenty-one, six months pregnant. Purpura four days ; then rapid onset of increasing purpura, with haemorrhages from nose, gums, kidneys, and stomach. Miscarriage sixth day, with post-partum haemorrhage. Death on eighth day, four days after the acute onset. (Puech, Annales de Gynecologies xvi., 1887, p. 273.) 2. Female, aged thirty. Five previous normal labors. Seven months preg- nant. Purpura, with miscarriage in a few hours Avith post-partum haemorrhage. Death on second day. (Phillips, Brit. Med. Journal, Nov. 13, 1886.) 3. Female, aged thirty-two. Seven previous normal labors. Seven months pregnant. Purpura, haemorrhages from nose and mouth. Miscarriage on third day, with placental haemorrhage. Recovery in two weeks. (Phillips, loc. cit.) When we study these acute cases together, we are struck with their similar- ity to the class of acute infectious diseases. The absence of assignable cause, the rapidity of the onset, the multiplicity and scattering of the lesions, the enlai-ge- ment of the liver and spleen, and the constitutional symptoms out of propor- tion to the lesions, seem to prove by analogy the assertion that we are dealing with an acute infection, the nature of which is at present unknown. Compar- ing these cases, however, with those of the subacute form, the identical symp- toms are found in each, and it seems most probable that in both forms we are dealing with the same disease in all essential features, differing only in the intensity and rapidity of the infection. As the infection in the subacute cases seems to be due to the presence of Letzerich's bacillus, it is more than possible PURPURA HEMORRHAGICA. 403 that the acute cases may be due to a more intense infection by the same germ. Much attention has been called to the relationship of essential purpura haemor- rhagica to two diseases of the hsemorrhagic group — purpura simplex and pur- pura rheumatica. Purpura simplex is due to a variety of causes. In some cases the cause is appai'ent, as in severe anemia, debility, after certain drugs, or occurring in infectious diseases. In other cases no cause can be found and the nature of the disease is obscure. In either we may have mild or severe constitutional symptoms. In purpura rheumatica we have not only simple purpura, but also pain and swelling of the joints. Formerly it was regarded as a separate disease from purpura simplex, but of late efforts have been made to associate them, purpura rheumatica being considered either as a purpui-a occurring in rheumatic sub- jects, thus accounting for the joint symptoms, or as a severe purpura simplex, in Avhich haemorrhages occur in and around the joints. The author regards the latter supposition as the more correct, as in all hsemorrhagic diseases, pur- pura hsemorrhagica, as well as scurvy, multiple sarcoma, etc., the joints may be affected, together with the appearance of purpuric spots. If this view be correct, why regard them as separate diseases? Is it not justifiable to consider purpura rheumatica as an intenser form of purpura simplex with haemorrhagic joint lesions? If purpura hgemorrhagica be due to an infection, may not the cases of pur- pura simplex occurring without known cause, and cases of purpura rheumatica not associated with rheumatism, be considered as lighter forms of the same infec- tion, especially as in some cases of subacute purpura hgemorrhagica, purpura or purpura with joint symptoms may be the most marked features, the free haemorrhages being of very slight importance, often not appearing for several days after the other symptoms? Even in the acute form is this seen, as the case of Puech's, cited on the preceding page, illustrates, the purpura alone existing four days before the onset of acute symptoms. In support of this theory may be cited cases of secondary purpura hgemor- rhagica, such as those occurring after the administration of certain drugs, in which small doses in some patients produce merely purpura, while large doses cause, in addition, free haemorrhages and marked constitutional symptoms. The only difference seems to be that in one case we are dealing with a cause unknown, though probably bacterial, while in the other the cause is known, and by its intensity we have all grades, from simple purpura to purpura hgemor- rhagica, even of an acute type. n. Secondary Purpura Hemorrhagica. Under this class we include those cases of purpura and free haemorrhages which complicate some existing disease or to which a definite cause can be assigned. In nearly all of these cases we may have either a simple purpura or purpura haemorrhagica with constitutional symptoms of a mild or severe charac- ter, in some even running a fatal course. Only a brief mention can be made of these cases. (1) Gases due to the Administration of Certain Drugs, potassium iodide, chloral, quinine, and salicylic acid being the ordinary drugs causing such a result. There is a great difference in their action in different patients, some developing no symptoms, others a simple purpura, while in still others we have a striking exhibition of spreading purpura, free and internal haemorrhages, with coma, collapse, and even death. These various types can proceed from the 404 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. same cause acting more intensely upon some patients than upon others, either from a maximum of cause on the one hand or the minimum of personal resist- ance on the other. (2) Cases which Accompany or closely Follow Severe Infectious Diseases, such as acute atrophy of the liver, snake-bites, typhoid fever, pneumonia, and the exanthemata ("black measles,"" etc.). In these cases we have various grades, from simple purpura up to acute purpura h?emorrhagica. Many authors attrib- ute such a complication to an added infection of essential purpura hsemor- rhagica complicating the primary disease. Henoch, for example, reports a case of a child with lobar pneumonia in whom a supposed infection of pur- pura hsemorrhagica occurred two days after crisis, causing death from collapse in twentv-four hours. If a drug like potassium iodide will so disorganize the blood or render pervious the blood-vessels, why may not the poison of an infectious disease produce the same result Avithout supposing an added infection of a new disease ';' It is no argument against this view that purpura haemor- rhagica may appear after the crisis, because we know that a temperature crisis does not mark the end of the disease, but only, as Fraenkel has recently demonstrated in pneumonia, the end of the fever-producing quality of the infecting germ. (3) Cases of Severe Jaundice may be accompanied by purpura and haemor- rhages. These seem to be due to the disorganization of the blood from the cholaemia. (4) Cases of Profound Ancemia, Leukcemia, or Pseudo-leukcemia, and of Exhausted and Cachectic Conditions. — In these we may have simple purpura, purpura hasmorrhagica, or continued haemorrhage after operations or injuries. We do not know whether to attribute these haemorrhages to blood-changes or to changes in the wall of the small arteries. (5) Cases of Neic-horn Infants with Congenital Syphilitic Changes in the Arterial Walls, producing purpura, bloody sweating, and free haemorrhages, especially from the umbilicus. (6) Cases of Neio-horn Infants U'ithout Syphilitic Parentage. — This form, according to Partridge, occurs in about 1 per cent, of cases, with a mortality of 60 to 75 per cent. He attributes its causes to the change of functional activities and to the altered circulation, allowing a brief interruption of the nutrition of the vessel-walls suflBcient for the transudation of their contents. (7) Cases complicating Malignant Endocarditis, the purpura and haemor- rhages being probably due to embolism of the capillaries by vegetation-frag- ments, and their subsequent degeneration and rupture. (8) Cases of Multiple Sarcomata, u'ith Purpura, with free haemorrhages, purpura, rheumatic pains, and fever. It is hard to say whether these result from malignant cachexia, with blood-changes, or from emboli of sarcomatous fragments lodging in the small blood-vessels, causing their degeneration and rupture. (9) Cases occurring after Fright, Beep Emotion, Hysteria, and Hypnotism. In these cases the haemorrhages seem to be due to vaso-motor relaxation or to enfeeblement of the arterial walls sufficient t^ allow of the escape of their con- tents. This latter explanation is Avarmly endorsed by Weir Mitchell. SCORBUTUS. BY WILLIAM PERRY NORTHRUP, M. D., New Yoek. Infantile Scurvy is a constitutional disease characterized by marked anaemia, spongy gums, excessive tenderness, swelling and inability of the lower limbs ; it is also characterized by a rapid recovery after corrected regimen. Etiolog"y. — The most frequent direct cause is prolonged feeding upon patent prepared foods and canned condensed milk ; or, to state this point more directly, jiersistent deprivation of fresh food. It most frequently occurs in the first eighteen months of life. England is the source of most of the reported cases and of most of the literature of scurvy in children. To W. B. Cheadle and Thomas Barlow of Great Ormond Street Hospital is due the credit (the former) of " having first shown on clinical grounds the true affinities of this form of infantile cachexia," and (the latter) the anatomical nature of the disease determined by post-mor- tem examination. Professor Heubner of Leipzig has collected recently-pub- lished cases outside of England, estimating the entire number at about 50. Of these, Heubner has observed 4 cases ; Rehn, of Frankfort, 7 ; Pott, 2 probable cases ; and Northrup, 11 cases from American practice. At the present time 4 more have been added to the American list. The reader will find in this book, for the first time, scurvy put down as a disease occurring in the United States. The explanation is, that this cachexia has been ascribed to rickets, and has found its way into literature as "acute rickets," or gone astray under purpura hgemorrhagica. Rickets predisposes to scurvy, but the two diseases are not regularly associated. They occur in children of the same age, and are induced by causes somewhat similar. Of the 15 cases collected by us, rickets was noted in 3, not mentioned in 4, and recorded as absent in 8. Rickets is a disease of general malnutrition, but no rickety child or other will become scorbutic unless its blood lack that certain something which is supplied by fresh food and fruits. Scurvy develops in wealthy and squalid environment alike. Two of our cases Avere in princely surroundings and tended with devoted care. One was a foundling. The first case in the writer's seven was fed upon one of the proprietary foods from the fourth to the sixteenth month of its life. The child thrived for a time, but "was rather "backward" in development. On the other hand, it seemed satis- fied with its food and never gave any evidence of rickets. Another case, aged twelve months, was said by its mother to have been failing for two months. The child had been put out to board during this time, and its food had consisted entirely of condensed milk. Dr. Delafield has furnished an interesting and unusual case of a child three 405 406 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. Fio years old brought to him with obstinate diarrhoea. He prescribed a diet of scraped meat, °and sent the child to the country for three months. In Sep- tember the child wa? brought again to him with this history: it had recovered so satisfactorily from its diarrhoea, had seemed to thrive so well on the meat, that it was thought best, in order to perpetuate this happy state, to adhere con- scientiously to the same regimen. As a result, the child on its second visit to Dr. De'lafield presented typical signs of scurvy. On a rational diet the child speedily recovered. Three of our cases w^ere fed exclusively on proprie- tary food for months; another upon a mixture of proprietary food and condensed milk. There is no evidence that sterilized milk has caused scurvy, nor any reason to believe that Pasteur- izing milk predisposes thereto. The reactionary tendency against the routine use of patent baby-foods is justified. There seems no greater surviving fallacy current in medical practice than routine feeding of tender infants upon the patent products of commercial firms. Pathological Anatomy. — The anatomical changes are chiefly due to hemorrhage, the most striking and characteristic being the subperios- teal haemorrhage of the femora. A typical case of scorbutus in a child eigh- teen months old, an inmate of the New York Foundling Asylum, came under the writer's obser- vation. The autopsy gave the following results : The child was emaciated, its eyelids swollen and ecchymotic. The gums Avere prominent, spongy, dark, covered with dried blood, the lips blood- stained. The pale, thin face, with two " black eyes," gave a most striking appearance to the dead baby. The main interest lies in the condition of the legs. As regards the organs, it is sufficient to say there were no hi^emorrhages. but extensive pleuro-pneumonia of the left side. Left thigh symmetrically enlarged, larger than the right, though both were obviouslv above normal in size. Left femur was normal at its upper ex- tremity, epiphysis and end of shaft. The lower half was invested with a black, grumous subperi- osteal layer of blood having a thickjiess of two or three millimetres. The lower epiphysis was detached ; the lower end of the shaft macerated, eroded, and soft, lying loose in the black, dis- integrating blood-clot. The femur of the right leg was surrounded for its lower two-thirds by a thinner, black, subperiosteal blood-layer. The lower epiphysis was not detached, though both it and the shaft w^ere congested. No haemorrhage into any joints. The i-ight and left tibiae were surrounded by a thin, dark haemorrhagic layer beneath the periosteum, and the proximal por- tions of both were congested. The fibulae, likewise the bones of the upper ex- tremities, were normal. Sp)€cimen from a case of Infantile Scurvy, showing subperiosteal ha?m- orrhage about femur and tibia of the side less affected. (Drawn from the specimen pre.served in the Museum of the College of Physicians and Surgeons, N. Y.) SCORBUTUS. 407 Microscopical examination of the bone disclosed no syphilitic or rachitic changes, and no inflammatory changes in bone or periosteum. The softened macerated bone gave no evidence of suppuration ; but there was moderate con- gestion of the fellow femur and of the upper extremities of the tibiae. A small amount of blood, dark and disintegrated, was found in the intes- tines ; no lesion discovered. The accompanying illustration (Fig. 1) is drawn from a specimen which consists of a lateral half of the lower limb of the side less affected. The above case corresponds very well to published English cases, and may be assumed to fairly represent the lesions of a well-marked typical case. It is worthy of note that the bone of the shaft was smooth, showing no signs of inflammation, and that the separation of the epiphysis was apparently due to the fracture of the softened bone above the normal line of junction of shaft and epiphysis. But few autopsies are on record, and now that the disease has been classified and its treatment understood, deaths and autopsies will be very rare indeed. Symptoms. — The patients are usually anaemic, flabby, wasted, having the symptoms of marasmus ; irritable, fretful, showing a disinclination to being moved or handled. They may or may not have signs of rickets. The symp- toms thus far enumerated point to disturbed nutrition, and are not character- istic. After four to six weeks the child manifests pain on handling, excessive tenderness, especially on moving the limbs. At this time fusiform or cylindrical swelling of one thigh is noted, the limb being first flexed, later lying helpless and straight. This condition has been frequently diagnosticated as rheumatism, and treated for such. If we recall the lesion, the position and helplessness of the member are easily explained. The fusiform swelling and flexure are the result of the subperiosteal haemorrhage about the shaft of the femur ; the straighter and helpless condition of limb follows upon the further haemorrhage and separation of the epiphysis. Finally, swelling and bleeding gums (if teeth are present), ecchymoses about the eyes, purpuric spots, hgematuria, and intes- tinal haemorrhage complete the picture. The temperature may continue normal, or may rise as high as 101° or 102° F., with or Avithout albuminuria. The following are illustrative cases : Case I. — T^^pical scurvy occurring in rich surroundings. The child had b^en treated for rheumatism without success. At the time of the consultation the father and mother of the little patient were present ; both were within the thirties, healthy and vigorous, the father looking like a hardy yachtsman. The family history on both sides was good. The family were luxuriantly housed in the most hygienic surroundings of up-town New York. The child at this time was sixteen months old, was the second born, a female, thriving very well in the early months of life ; at the fourth month the mother's milk failed to be of sufficient quantity, and quickly thereafter ceased altogether. The first-born is still living and robust ; the mother's milk had after a few months been insufficient for it, but the child continued to thrive. After the failure of the mother's milk in our patient's case one of the proprie- tary foods was given her. By some misunderstanding this food was diluted with water and milk, the proportion of the latter being too small. For a time the child thrived very well apparently, though it was rather backward. Its digestion was good, its bowels reasonably satisfactory, and it seemed satisfied with its food. It never gave any evidence of rickets; teeth in normal number made their appearance at the usual time. Three weeks before the visit spoken of (this fact was subsequently elicited 408 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN, after close questioning) the nurse had noticed some change in the child's gums. The change was not marked. One week hiter than this the patient developed trouble in the right lower limb, evidenced by worrying, sensitiveness on handling, and a tendency to keep the limb nearly straight. There seemed no reason why the case should not speedily come out of its condition of slight depression, as the food was improved and antirheumatic treatment instituted. During the succeeding week very little is known concerning the child ; the parents were absent from home ; the family physician was not called ; the nurse drew no conclusions from the now rapidly changing gums, and as to the rheu- matism the progress was slow. The child cried on seeing a strange face, becoming alarmed also for the safety of its lame leg. In the wry face of crying the little patient fairly unbut- toned from betAveen its lips two rows of irregularly nodulated, purplish gums, from the summits of which the points of its teeth barely protruded. In the upper spongy row was a depression with ulcerated ivalls and sloughing shreds. The gums were dark, and bled freely in the act of crying from compression of the lips alone. There was nothing further abnormal about the face beyond a worried expression ; no ecchymoses, no petechias; conjunctiva were normal; no evidence of unhealthy condition of the mucous membrane of the nose. There was no history of nose-bleeding, no hsematuria, no hgemorrhages from the bowels. The child was now stripped of all clothing and laid upon its back on the bed. It continued to whimper, throAv its arms about freely, draw up its left leg ; as for its right, it could move it slowly, but only a little, and could not be induced to flex it. The right thigh uhis somewliat larger than the left, to observation ; by measurement it showed a difference of about two and a half inches, which, consid^ying the thin thighs of the small patient, augured a marked difference. The enlargement was fusiform, greatest just above the knee. Apart from the spongy gums and swollen thigh there were no external manifes- tations. This case promptly recovered on corrected regimen,^ and will be mentioned again under Treatment. Case II. — Fatal scurvy in a child of eighteen months ; Autopsy. This child was an inmate of the New York Foundling Hospital, and was what is called a " nurse-baby ; " that is, she was nursed by a mother who, in addition to her own baby, nursed a second of about equal age. Her own child thrived ; the second furnished the example of malnutrition and the pathological speci- men already referred to. Since we are considering a case of scurvy developing in a breast-fed {sic) child, it is well to bear in mind the above facts, and the added fact that nearly all babies nursing two at one woman require more or less artificial food. We are justified in forming our own conclusions as to which was nursed more and which less ; we know which baby was hers and which was not, which thrived and which developed fatal scurvy. Briefly, the history of the illness was as folloAvs: The foster child when sixteen months old was observed to be failing, and, as the history reads, " on account of impaired nutrition was taken from the breast and was given vege- table acids." In the seventeenth month of life, which was one month before death, the right leg and knee became swollen and tender. Temperature was 101° F. After two days the symptoms seemed temporarily to disappear. Two weeks before death, and six weeks after the weaning, the child appeared to be very sick ; her gums were swollen, smoky-black, and bled freely ; two days later her left eyelid became swollen, black, having the appearance of the classical "black eye." Temperature thus far continued about 101° F. One SCORBUTUS. 409 week later there developed the physical and rational signs of pneumonia. At this time her other eyelid became ecchymotic and the other thigh markedly swollen. During the remaining days of life the little patient became excessively anaemic, having a metallic pallor, which gave a particular wretched appear- ance with the contrasting ecchymoses about the eyes. Her passages were black and pasty ; no petechise ; the child failed rapidly and died with pronounced symptoms of pneumonia. (For autopsy see "Pathological Anatomy.") Case III. — (Dr. Chas. H. Richardson of the North Eastern Dispensary.) Annie K , aged twelve months, was brought to the dispensary by her mother with the history of "failing" for nearly two months. The child was healthy for some time after birth, when the mother was obliged to work, and of necessity the baby was "farmed out." She reported the food as having been con- densed milk. The child had recently vomited blood, passed blood from the bowels, and presented small spots of subcutaneous haemorrhage. The gums were slightly softened, and, according to the mother's account, the inside of the mouth had. been black. Both legs were enlarged to considerable more than double their normal size. Epiphyseal ends showed marked enlargement. Limbs very tender, hard, and pitted slightly on pressure. " Head sweats. Temp., 100|°." The following paragraph gives the case an added interest and accuracy : " The swelling of the limb being due to subperiosteal haemorrhage, added to subcutaneous oedema, I wished to see the character of the effusion next the bone. I thereupon passed an aspirating needle down to the femur and drew off some of the effused fluid. It consisted apparently of pure blood which microscopically showed the red globules somewhat ragged and disintegrated, and the white ones somewhat increased in number." At this point the case escaped from observation and the history ends. Case IV. — Dr. W. F. Lockwood of Baltimore furnishes the following : " Aug. 12th, Mrs. W. , whose family had been in the country during the warm weather, asked me to visit her child, thirteen month old, ailing for some weeks with diarrhoea varying in severity, but never entirely relieved. Of late she had thought the child suffered pain in the lower limbs, that it screamed in an unusual way at night, especially when moved or touched, and that there was increased fretfulness during the day. She referred also to some spots ' like old bruises ' on its legs below the knees, more marked on the right. " It had been nursed until six months old, after which time it had taken almost exclusively a proprietary food. "Examination showed the child fairly well nourished, rather anaemic, com- plexion sallow. No evidence of rickets, no swelling along shaft or enlarge- ment at ends of bones. Ill-defined ecchymotic spot on left leg, but plainer on the right. The right leg semiflexed and everted. No tenderness manifested on gentle manipulation of body or limbs. Gums showed dusky purplish fold at root of each tooth. They had bled occasionally for some weeks, and the stool had pretty constantly been streaked with blood. Pulse and temperature were normal. The diagnosis of scorbutus was made and directions were given to change the diet to fresh milk undiluted, potato, and orange or peach juice. A few days after my visit the mother reported the child improved in every way. The diarrhoea had stopped, and there were no screaming or restlessness at night. A second visit was not required, and the improvement, I have heard, has con- tinued." 410 A3IEBICAN TEXT-BOOK OF DISEASES OF CHILDREN. Case Y. — Dr. G. H. Whitcomb, of Greenwich, N. Y., has published a most illustrative ease {Archives of Pediatrics, Oct., 1891, p. 760). The child, a girl, ■was eleven months old ; after fifth month -svas fed exclusively on artificial food during which time she grew very fat, " seemed to thrive famously." " When a little over ten months old she became petulant, and evinced a disinclination to move or be handled. The legs were partially flexed and remained rigid. Any attempt to straighten them elicited screams. The gums were spongy and bled frequently ; muscular pains were so severe as to deprive the child of rest." " The phvsieian at that time in charge diagnosticated and treated rheumatism After tcH days the family went to Rome where the diagnosis of rheumatism was approved and alkaline treatment pursued for two weeks after which they came to Greenwich." In Dr. Whitcomb's graphic account occur such expressions as the following : " screams when handled ; . . . . limbs resembled Bologna sausages ; . . . . gums Avere spongy, ecchymotic blebs discharging sero-sanguinolent fluid ; . . . . seven teeth; .... no evidence of rachitis.'' Treatment compressed fresh milk, rare-broiled beefsteak, and sweet oranges. In three weeks the child was restored to complete health. The doctor believes the scorbutus to have been caused by the exclusive use of prepared food, and he concludes that " no cereal or chemically prepared food can nourish perfectlv." but should be supplemented Avith fresh milk, meat, and fruit juices. Diagnosis. — In a well-marked case the recognition of scurvy is not diffi- cult. Exquisite sensitiveness of lower limbs, one or both; swelling of the thighs, fusiform or cylindrical, firm (sometimes oedematous), non-fluctuating, without marked local heat; stiff"ness, inability ; pseudo-paralysis of the limb ; deep thickening of the femur (late); crepitus at lower end (late). Of the gums the characteristics are swelling, sponginess, bleeding on slight pressure, dusky purplish color, "smoky." Not least important is the prompt improvement on corrected regimen. Prognosis. — Recovery may be confidently expected even in well-advanced cases, provided the proper nursing can be obtained. Death is usually due to exhaustion. In cases not too far advanced the results of proper treatment are most satisfiictory — little short of magical. Treatment. — Correction of fiiulty regimen is usually sufiicient to produce a marked change in a few days. So marked and so prompt, indeed, is improve- ment that it may be considered a satisfactory confirmation of diagnosis and a characteristic of the disease. Briefly, give fresh milk and orange-juice. Referring once more to the* memorandum of Case T (under Symptoms), the child was removed at once to the country, its proprietary mixture was stopped, and in its place was given fresh cow's milk, expressed juice of beef, baked potatoes, etc. The one thing which this scurvy patient seemed to crave, for which she reached out, which she seized with ravenous avidity, was orange. The child could hardly be restrained till she held the fruit in her grasp, and then proceeded to souse her lips and nose in the juice. Improvement began at once ; in five days the gums were markedly better, in ten entirely normal. As for the thigh, at the end of ten days the improvement in its condition was marked, and a month later the child was standing on her feet. A slight thickening over the femur could be detected for a few days longer, at the end of which time the patient seemed absolutely well. General supporting treatment should be given in the exhausted condition of advanced cases : a few drops of brandy, well diluted and administered judiciously at one to four hour intervals; abundance of fresh air; cod-liver SCORBUTUS. 411 oil; albuminate or peptonate of iron. The condition of tlie bowels may require attention. „ ^ . . * The care of the limbs depends upon the extent of the lesion. A separation of epiphysis requires plaster splints. Usually, nothing need be done for the swelling or to assist absorption of the effused blood. For the swollen gums, if bleeding be troublesome, it may be necessary to apply some mild astringent, glycerite of tannin with a few drops of carbolic acid being recommended. PART VI. DISEASES OF THE DIGESTIVE ORGANS DISEASES OF THE MOUTH AND DENTITION. By F. FORCHHEIMER, M. D., Cincinnati. I. DISEASES OF THE MOUTH/ The mouth of an infant differs in many I'espects from that of an adult or even a child: up to the third or fourth month of life it is to be looked upon merely as a passage-way for food. Then comes the first outpouring of saliva, and with it the functions of the mouth are increased by that of incipient digestion, which reaches its full development after a period that varies in indi- vidual cases. The lack of saliva produces more or less dryness of the infant's mouth, a coating of the tongue due to epithelial cells, detritus, and food, and a peculiar glistening appearance by reflected light. After saliva is formed the child does not, at first, know what to do with it, so that, even when normal in quantity, the greater part of it is not swallowed. For most of the inflammations of the mouth the etiology is still a matter of surmise. While there can be no doubt that lower forms of life must play a very, important role in their production, yet as a matter of fact but few forms of stomatitis can be definitely ascribed to this cause. The mouth is a veritable culture-tube for microbes and lower forms of life, but, as a rule, they do not produce disease. General conditions of the patient must seriously be taken into consideration (syphilis, rickets, scurvy) ; possibly these may produce a soil favorable to low conditions of life, resulting in the production of troubles in the mouth. Local conditions within the mouth must always be sought in examining a case — lack of cleanliness, rough attempts at cleansing, sharp or diseased teeth, the introduction of irritants or poisons ; while, on the other hand, causes may be found only in diseased conditions of remote organs. One important fact must always be taken into consideration, that the glands of the mouth are not only secretory, but also excretory, so that substances taken into the circulation, as well as others formed within the body, may leave the body by means of these glands and produce local lesions. In the matter of treatment care must always be exercised in removing the cause of the disease ; where this is impossible, purely symptomatic treatment is called for, and this, in the main, is antiseptic in nature. The most potent mouth-antiseptics are potassium chlorate, potassium permanganate, silver nitrate, ' For a more detailed description of these diseases see Diseases of the Mouth in Children (non-surgical) Forchheimer. 412 DISEA8ES OF THE MOUTH. 413 and sodium salicylate. Each one has its own indications, but the first and second are almost universally serviceable. Potassium chlorate, especially, when used internally, requires cautious administration on account of its effects upon the blood and the kidneys. It is safe to sa^'^, however, that the danger has been largely over-estimated by some, and in comparison with the frequency with which the drug is used the number of cases of poisoning is exceedingly small. The examination of the mouth should be thoroughly conducted, without force, but in such a way that all parts can be seen to advantage. It is necessary to insist upon this part of clinical examination, since, simple though it be, it is frequently neglected, so that very valuable aids to diagnosis in many diseases are overlooked. The classification which follows is one which is principally based upon clin- ical data ; it is completely satisfactory as a working formula up to the present, but will undoubtedly require revision in the future. The term "stomatitis" is retained for many reasons, not the least important being that it has been used quite universally. The following are the forms of stomatitis: I. Stomatitis catarrhalis ; II. Stomatitis aphthosa ; III. Stomatitis mycosa ; IV. Stoma- titis ulcerosa ; V. Stomatitis gangrenosa ; VI. Stomatitis crouposa ; Stoma- titis diphtheritica ; VII. Stomatitis syphilitica. I. Stomatitis Catarrhalis. Also called simple stomatitis, of which there are two kinds — local and general. Etiology. — Two things must be taken into consideration — an irritant and the mucous membrane. In healthy children the mucous membrane resists to a greater extent than in children sick with any disease whatsoever. The most favorable conditions for the production of stomatitis catarrhalis are to be found in children with acute febrile disease and in bottle-fed babies. The irritants are either mechanical, thermal, chemical, or to be traced to some lower form of life acting mechanically or chemically. In healthy children teething does not produce stomatitis, and it is denied by many that this process is even a predisposing cause. Lack of cleanliness, over-cleanliness, and food introduced at too high a temperature are common causes for this trouble. Many of the acute infectious diseases produce stomatitis catarrhalis, which then precedes the appearance of the characteristic lesions within the mouth. Nearly all other forms of stomatitis are preceded by this form — most especially is this the case with stomatitis mycosa ; and all other forms are associated with more or less catarrhal inflammation. In all probability, substances excreted by the glands of the mouth, as the result of faulty digestive processes in the intestines or of incomplete elimination, will be found to be of vast importance in the etiology. This will be the most rational way of explaining the frequent concurrent appearance of diseased processes within the mouth and the intestinal tract. For the localized form it is a local UTitation — a sharp tooth, a discharging abscess, or the rubbing of the gums to facilitate teething. Symptoms. — We may recognize two varieties, the erythematous and the true catarrhal. In the erythematous form the whole mucous membrane of the mouth is of a deep-red color, produced by hypergemia. The blood-vessels are sometimes subjected to such great pressure that rhexis occurs, or red cor- puscles may be forced into the submucous tissues, and the haemoglobin may there be changed to hsematoidin, with a resulting distinct yellow discoloration. This condition is frequently found in the mouth of the new-born ; erythema 414 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. of the mouth may be looked upon as normal during this period of life, requir- ing no treatment except gentleness, and is of no special importance. In pertussis and the acute exanthemata there is produced a peculiar form of erythematous change. In pertussis and measles it consists of a blue tint given to the tongue and the buccal cavity ; in scarlatina the whole mouth is more or less reddened, and in all the acute exanthemata the eruption appears in ■well-defined places in the characteristic form seen upon the skin. In general stomatitis catarrhalis we have all the symptoms of an inflam- mation — swelling, pain, heat, redness. The whole lining of the mouth is hyperjemic ; there is more or less puffiness, especially where there is pressure, and here the mucous membrane is somewhat paler. The lips frequently become more tense, and the mucous membrane is covered with small, round prominences due to swelling of the muciparous follicles. When the ducts of the latter become tightly closed the glands dilate, and there are produced cysts, the contents of which are clear, viscid mucus. We also find slight epithelial abrasions, sometimes leading to the production of a deeper process — at all events, important in that they may become the seat of infection. The tongue is coated, at first dry and white, then yellowish or grayish, and, as secretion increases, whole flakes of this coating are Avashed oif, leaving red spaces partially uncovered. The tongue never looks like the scarlet-fever tongue, since the catarrhal process seems to aff"ect only the superficial layer of epithelium, sparing the fungiform and even the bases of the filiform papillae. When this process in the mouth is the result of long-continued fevers, the appearance changes; nutrition to all epidermal structures being less active, the tongue and the mouth suff'er comparatively more than when the process is purely catarrhal. In nearly all the inflammations of the mouth the lymphatics become in- volved, and the intensity of the stomatitis can be measured, as a rule, by the degree of involvement of the glands. Increased temperature is observed (in rare instances as high as 104° F. in the rectum), the prominent symptoms, however, being local. Of these the most important is pain, producing restless- ness, fretfulness, and more or less difficulty in nursing. With this, when the child is old enough, there is increased flow of saliva, producing, sometimes, irritation of the skin upon the lower lip or eczema of the face. Prognosis. — As this is usually an acute process of moderate intensity, the prognosis is good. Indirectly, there may be produced loss in weight, dyspepsia, catarrhal conditions of the intestine, continued enlargement of the glands, possibly tuberculosis, and, therefore, a vulnerability of the mucous mem- brane, so that the smallest local irritant Avill be followed by a return of the stomatitis. Treatment. — In the majority of instances the disease runs its course without any special treatment. The cause must be removed when possible. Next, relief must be given to symptoms ; cold water, applied by means of cotton, either wrapped around a stick or the finger of the nurse, or small pieces of ice Avrapped in a handkerchief. All food must be given cold ; usually this causes least pain ; sometimes the opposite Avill be found necessary. Much comfort will be given by frequent and gentle washing of the mouth with ice- cold sterilized water, to which there has been added boric acid fl-3 per cent.), sodium biborate (2-3 per cent.), zinc sulphate (|-1 percent.), sodium salicylate (1 per cent.), etc. The addition of any of these is not imperative ; chlorate of potassium is unnecessary and without value in this form of stomatitis. Silver nitrate (|-1 per cent.) is the most reliable of all remedies ; if the stomatitis does not disappear in four or five days, the mouth must first be DISEASES OF THE MOUTH. 415 thoroughly cleaned, and then pencilled with this weak solution once a day. Where there is loss of epithelium the spot should be touched with the mitigated stick, which can be accurately applied by first melting and then dipping a silver probe into it. Cysts should be duly opened, and their walls should be cauterized when necessary. n. Stomatitis Aphthosa. Aphtha (from a(pda, an eruption or ulceration) is a subepithelial vesicle of different color from the mucous membrane upon which it occurs, and is surrounded by an areola which changes in a peculiar way during its existence. It has nothing to do with the muciparous follicles, appearing in places where there are none; it is therefore not follicular. Etiology. — No uniform local cause has ever been found. Micro-organisms, usually pus-producers, have been observed, but no connection could be discov- ered between them and the disease. Aphthae have been produced artificially (caustics, the end of a burning match), but no one has ever succeeded in pro- ducing the whole series of symptoms associated with this form of stomatitis. It is said that the disease is most common between the tenth and thirteenth months of life (Bohn), and therefore teething has something to do with the eruption. However this may be, we find stomatitis aphthosa associated with a. great number of diseases — pneumonia, ague, gastro-intestinal catarrhs, the acute exanthemata, etc. We must therefore look for the cause in a general, not a local, disturbance, and as the disturbance is the same as herpes, the same etiology will be found to hold good for aphthae as for herpes. The dis- ease is not contagious, but the same cause may not infrequently produce it in several members of the same family, and usually those are selected whose diges- tive tracts are either temporarily or permanently Aveak. The foot-and-mouth disease in cattle can be definitely accepted as causative, but as this disease is very rare in this country, it can be almost absolutely excluded as an etiological factor. In a recent epidemic near Berlin studied by Siegel, an ovoid bacillus 0.5// long was found in all cases ; only those con- nected with the animals had local lesions, but were protected in a measure, infection taking place from man to man. The conclusions arrived at by the author in regard to the etiology of this disease are as follows : It is a disease produced by some form of deleterious material in the circulation, which may have its origin in various processes, bac- terial or otherwise. It may, therefore, be of various kinds. This material acts upon a nerve or nerves, or upon a nerve centre or nerve-centres, and produces an herpetic eruption which is the aphthous process. Symptoms. — On the part of the general system there is a great diversity, depending largely upon the patient affected. We may have, for two or three days preceding the eruption, manifestations pointing to the inception of almost any disease common to children — vomiting, constipation, high fever, pain in the throat or mouth, enlargement of lymphatics, a slight cough,- depending upon the localization of the disease, and even nervous symptoms, so that it will be almost impossible to foretell what is coming. On the other hand, some patients are very little affected beyond a slight rise of temperature, fretfulness, and loss of appetite. An examination of the mouth made at this period usually reveals stomatitis catarrhalis, sometimes a whitish spot upon the tonsil. Then, possibly the next day, the characteristic eruption appears with lightning rapidity. This consists of white or yellowish-white subepithelial spots, single or in groups, surrounded by an areola, and developing anywhere within the mouth, not uni- 416 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. lateral, and sometimes extending into the pliarvnx, and possibly also into the larynx. After from twelve to thirty-six hours the epithelial coating is soaked off, and there is left the so-called aphthous ulcer. After a few days more the floor of the ulcer is clean or the exudate is lifted up between regenerating epithelial cells ; it is lifted beyond the level of the mucous membrane, and finally disappears. Some aphthae are absorbed without going through this normal course. They appear in successive crops, and it is not unusual to have the course of the disease extend to from ten to fourteen days. The exudate is made up of fibres, indifferent cells, and various lower forms of life. No cic- atrix is left where these spots have been, showing that the submucous tissue has not been affected. The local symptoms are those' of stomatitis catarrhalis ; where denudation takes place there is more pain. The most common complication which occurs is stomatitis ulcerosa, and unless this is present the saliva in stomatitis aphthosa is neVer fetid — a matter of great diagnostic importance. In some instances the aphthiB are so numerous that the mouth looks as if it Avere covered by a diphtheritic membrane. A day of waiting will clear away any doubts on the subject, as by this time the characteristic denudation will have appeared. Prognosis. — The prognosis is absolutely good. The disease is self-limited, doing no harm except to interrupt the general thriving of the child. Infection with other poisons has been known to take place, but this, fortunately, is very rare. Relapses are very rare, and the small ulcers, as a rule, heal without difficulty. Treatment. — This is the same as that used for catarrhal ulcers — viz. the nitrate of silver. Permanganate of potassium may be used locally to great advan- tage (gr. iij to f 3J), but must not be looked upon as a specific. General treat- ment, as a rule, is not required, and when it is necessary it is purely sympto- matic. Laxatives, usually given early, seem to have no influence upon the process ; calomel does not abort it, and must be used according to the indica- tions wdiich govern its administration in other conditions. The poison has done its work before we are able to attempt to counteract its bad effects ; it is probably eliminated by the time we see the patient, and therefore all causal therapy is futile. Bednars Aphthce are found only in the new-born. They are shallow ulcers covered by a gray or yellowish coating, and found upon the soft palate, the posterior part of the hard palate, the palatine suture, always near the velum palati. They may be mistaken for the ulcers produced by the breaking down of milia or retention-cysts, or for that condition described by Epstein in which there are congenital defects in the mucous membrane filled up with epithelial detritus. These aphthae are always produced by violence in cleansing the mouth ; this explains their position and their course. They are rarely found in private practice except where the midAvife still holds absolute sway. Their course is benign, they require no treatment, and are only dangerous when they become infected. With the modern rubber nipples, when badly shaped, they some- times develop far forward upon the hard palate ; changing the shape of the nipple always results in their cure. m. Stomatitis Mycosa. This condition, commonly termed Thrush, is a disease produced by a pecu- liar fungus, first discovered by Berg of Stockholm, and called o'idium albicans by Robin. Rees and Grawitz were the first to show that the fungus is not an DISEASES OF THE MOUTH. 417 o'idium, but a saccharomyces. All later investigations agree in showing that it is not oidium, but all do not agree that it is saccharomyces albicans. For the present, however, until the exact position of the fungus is determined, it seems wise to adhere to the last name, saccharomyces albicans. Etiology. — The fungus is the only cause, but it must be deposited upon favorable soil to produce the disease. The saccharomyces albicans may be found upon every mucous membrane in the body, the alimentary, the respi- ratory, and genito-urinary : it has been found in the parenchyma of organs, as the brain and lungs, and in blood-vessels. It is usually carried to children by the nipple or by the nursing-bottle. The fact that weak and unhealthy chil- dren are most predisposed to thrush has been emphasized entirely too much : perfectly healthy children have thrush. It has also been stated that flat epi- thelium is necessary for the development of thrush ; this, however, can nO' longer be maintained, as we see the fungus on a great many surfaces lined by cylindrical epithelium. It is admitted on all hands, however, that catarrhal stomatitis exists either before or with the appearance of thrush. It is more than probable that this is the predisposing cause, and that it works mechani- cally — viz. by a dislocation of the swollen cells, preventing perfect protection to the mucous membrane, and allowing the spores of the fungus to find a place for development. Anything producing this mechanical injury to the mem- brane of the mouth, such as badly-formed or hard nipples, Avill act in the same way. The younger the child or the weaker, the more successful will be the implantation of the saccharomyces, because the function of motion of the tongue and jaw will be least developed. The disease is therefore found especially in infants reduced by illness, and in older children in connection with diseases that are followed by great loss of strength, such as long-continued fevers, wasting diseases, or those in which motion is very much impaired. The fungus is found in two forms, depending largely upon the culture- material — the yeast form and the globulo-filamentous form (frequently called mycelium). There is no ascospore ; therefore, according to Roux and Linois- sier, the fungus is not a saccharomyces. The chlamydospore has, however,- not been satisfactorily worked out. Propagation goes on in three ways — by filaments produced from conidia, by isolated conidia, and by spores. Patholog-y. — The first lodgement comes between the epithelial cells of the mouth, and from this the growth works its way toward the free surface and toward the mucous membrane proper. In the direction of the free surface the growth is not so luxuriant, but in both directions it is principally in the myce- lium form. In mucous membranes lined by flat or squamous epithelium the growth of the saccharomyces is facilitated by the relation of the cells to each other ; in membranes lined by cylindrical epithelium growth takes place, but not so readily, because there is but one layer of cells. After the first develop- ment grow^th goes on very rapidly : after having found a nidus, the cells are pushed aside, surrounded by mycelium, the whole forming the characteristic thrush-spot. Pus is rarely produced ; when this does occur the afi"ection is of a complex nature. The growth begins in small spots, sometimes one, some- times more ; from these infection spreads, and at times the whole mucous mem- brane is covered with a rich growth of the saccharomyces. Symptoms. — Preceded or accompanied by stomatitis catarrhalis, the local symptoms vary with the intensity of this process. Frequently no symptoms are present, and the existence of the small spots is the first indication of the presence of thrush. These vary in size, seem a part of the mucous mem- brane, are usually of a grayish-white, creamy color, and may or may not be elevated above the surface of the mucous membrane. They appear first upon 27 418 AMERICAN TEXT-BOOK OF DISEASES OF CHILDREN. the tongue and cheeks, then frequently upon the lips and soft palate, and may be found upon the tonsils, the phaiynx. or the oesophagus. With only mode- rate care of the mouth they seem to last indefinitely ; -without care they spread rapidly, and instead of the spots we may see membranes, in the case of the oesophagus whole casts being formed, which fill its lumen and often prevent swallowing. In hospital practice thrush has proved a formidable disease ; in private practice it amounts to nothing more than a local disturbance, unless neglected. In the latter class of patients there is always associated some gastro-intestinal disturbance, which may prove serious if not fatal. In debili- tated subjects — and thrush, from the mechanical reasons pointed out before, is more common in such — these gastro-intestinal troubles may be the aifection which terminates the child's life. When the membrane drops off there is left a slight abrasion which may become the focus of infection by any other morbific agent. But it must not be inferred that thrush occurs only in debilitated or sick children. It may occur in children that seem perfectly healthy, although care- ful investigation will always reveal some lesion in the mouth which has pre- ceded the thrush. Again, not every child with stomatitis mycosa has gastro- intestinal symptoms : the food carrying saccharomyces frequently carries other lower forms of life capable of producing diarrhoea, but in properly-treated cases these symptoms are wanting, and when taken early enough thrush is local, and local only. The thrush-spots develop within the epithelium, and examination by reflected light will show this ; the spot is often surrounded by a narrow ring of injected blood-vessels. Removal from the mucous membrane requires considerable violence. The next step in development is a pushing up beyond the level of the mucous membrane, and after this more extensive infection of the mouth may be expected unless counteracted by treatment. At times the whole mass may drop off" and leave an ulcer, sometimes very intractable, or the many spots may coalesce to form a membrane. The differential diagnosis is not difficult if all the above be taken into consideration, and a positive
