Burns, Scalds, Frostbites, Etc.
Classes of Burns—Treatment—Burns Caused by Acids and Alkalies—First Aid Rules for Frostbites—Real Freezing—Ingrowing Toe Nail—Fainting—Suffocation—Fits.
BURNS AND SCALDS.—If slight, skin very red, unbroken.
First Aid Rule.—Cover with cloths wet in strong solution of baking soda in cold water. Dry gently, and spread with white of egg, thick.
If deeper, blisters, skin broken, thick swelling; there may be some bleeding.
First Aid Rule 1.—Stop pain quickly. Cut away clothing very gently. Break no blisters. Cover with Carron oil (equal parts of limewater and linseed or olive oil) and light bandage. Give fifteen drops of laudanum[9]every half hour in tablespoonful of water, till relieved in part or three doses are taken.
Rule 2.—Combat shock. If patient is cold, pulse weak, head confused, give tablespoonful of whisky in a quarter of a glass of hot water. Put hot-water bottles at feet.
Rule 3.—Quench thirst with pieces of ice held in mouth or a swallow of cold milk.
See page174for subsequent treatment.
A burn is produced by dry heat, a scald by moist heat; the effect and treatment of both are practically identical. Burns are commonly divided into three classes, according to the amount of damage inflicted upon the body.
First Class.—There is redness, pain, and some swelling of the skin, followed, in a few days, by peeling of the surface layer (epidermis) and recovery. Sunburn and burns caused by slight exposures to gases and vapors fall into this category.
Treatment.—The immediate immersion of the part in cold water is followed by relief, or the application of cloths wet with a saturated solution of saleratus or baking powder is useful. Anything which protects the burned skin from the irritating effect of the air is efficacious, and in emergencies any one of the following may be applied: starch, flour, molasses, white paint, or a mixture of white of egg and sweet oil, equal parts. Usually after the first pain has been relieved by bathing with soda and water, or its application on cloths, the employment of a simple ointment suffices, as cold cream or vaseline.
Second Class.—In this class of cases the inflammation is more severe and the deeper layers of the skin are involved. In addition to the redness and swellingof the skin there are present blisters which appear at once or within a few hours. The general condition is affected according to the size of the burn. If half of the body is only reddened, death usually results, and a burn of a third of the body is often fatal. The shock is so great at times that pain may not be at once intense. Shock is evidenced by general depression, with weakness, apathy, cold feet and hands, and failure of the pulse. If the patient rallies from this condition, then fever and pain become prominent. If steam has been inhaled, there may be sudden death from swelling of the interior of the throat, or inflammation of the lungs may follow inhalation of smoke and hot air.
Third Class.—In this class are included burns of so severe a nature that destruction and death of the tissues follows; not only of the skin but of the flesh and bones in the worst cases. It is impossible to tell by the appearance of the skin what the extent of the destruction may be until the dead parts slough away after a week or ten days. The skin is of a uniform white color in some cases, or may be of a yellow, brown, gray, or black hue, and is comparatively insensitive at first. Pus ("matter") begins to form around the dead part in a few days, and the dead tissue comes away later, to be followed by a long course of suppuration, pain, excessive granulations ("proud flesh"), and, unless skillfully treated, by contraction of the surrounding area, leaving ugly scars and interfering withthe appearance and usefulness of the parts. The treatment of such cases after the first care becomes that to be pursued in wounds generally (p.50), and belongs within the domain of the surgeon.
Treatment of the More Severe Burns.—If the patient is suffering from shock he should receive some hot alcoholic drink, as hot water and whisky, and be put to bed under warm coverings with hot-water bags or bottles at his feet.
The clothing must be cut away from the burned parts with the greatest care, and only a portion of the body should be uncovered at a time and in a warm room. Pain may be subdued by laudanum[10]; fifteen drops may be given to an adult, and the drug may be repeated at hour intervals in doses of ten drops until the suffering has been allayed. Lumps of ice held in the mouth will quench thirst, and the diet should be liquid, as milk, soups, gruels, white of egg, and water. The bowels should be moved daily by rectal injections of soap and warm water. As a matter of local treatment, the surface layer of the skin should be kept intact if possible. Blisters are not to be disturbed unless they are large and tense; if so, their bases may be pricked with a needle sufficiently to let out the fluid contents.
Carron oil (equal parts of olive oil and limewater) has been the common remedy for burns, and it is an efficient, though very dirty, dressing, useful if the skinis generally unbroken. It should be applied on clean, soft linen or cotton cloth, which is soaked in the oil, laid over the burned area, and covered with a thick layer of cotton batting and a bandage. When the skin is denuded, leaving a raw surface exposed, the burn must be treated on the same plan as wounds, and should be kept as clean and free from germs as possible. An ointment made of equal parts of boric acid and vaseline, spread thickly on clean cloth, is a good antiseptic preparation in cases where the skin is broken. It is best not to change the dressing oftener than once in two or three days, unless the discharge or odor are considerable. Fresh dressing is very painful and often harmful.
When the dressing is removed, warm saline solution (one teaspoonful of common salt in a quart of water) is allowed to flow over the burn until all discharge is washed off. Then the raw surface is dusted over with pure boric acid or aristol, and the boric-acid ointment applied as before. The cloth upon which the ointment is spread should be made free from germs by boiling in water, and then drying it in an oven and keeping it well wrapped in a clean towel except when wanted.
The same care is requisite as that described under wounds (p.50) in regard to cleanliness.
Very extensive burns are most satisfactorily treated by complete immersion of the burned limbs or entire body in salt solution (same strength as above), whichis kept at a temperature of from 94° to 104° F., according to the feelings of the patient. The patient lies in a bath tub on horsehair, or better, rubber mattress and rubber pillows; completely covered with water except the head. The urine and bowel discharges must be passed in the water, which is then changed, and the temperature is kept at an even mark by allowing warm water to continually run into the tub to displace that which runs out. The latter can be arranged by siphonage with a rubber tube. While this method requires more care, and running hot and cold water, it is the most comfortable treatment for these cases, usually attended by awful suffering, and at the same time it is most favorable to healing.
It is beyond the scope of this work to describe the various complications and the details of the after treatment in severe burns, including skin grafting, which may tax all the ingenuity of the skilled surgeon. It is hoped that the foregoing may give a clear idea of the treatment to be pursued in emergencies and may prove of some use to those who may unfortunately be compelled to care for burns during a considerable time without the aid of a physician.
BURN BY STRONG ACID.
First Aid Rule 1.—Neutralize the acid. Scatter baking soda thickly over burn, or pour limewater over it.
Rule 2.—Control pain. Wash off soda with streamof water. Apply Carron oil (equal parts of limewater and linseed oil or olive oil). Bandage lightly.
BURN BY STRONG ALKALI.—As ammonia, quicklime, lye.
First Aid Rule 1.—Neutralize the alkali. Pour vinegar over the burn.
Rule 2.—Control pain. Wash off vinegar with stream of water. Dry gently. Apply vaseline or cold cream.
BURNS CAUSED BY STRONG MINERAL ACIDS OR BY ALKALIES.—If acids are the cause, the skin should not be washed at first, but either chalk, whiting, or some mild alkali, as baking soda, should be strewn over the burn, and then after the effect of the acid is neutralized, wash off the soda with stream of warm water. Dry gently with gauze. Apply Carron oil or paste of boric acid and vaseline, equal parts. If strong alkalies have been spilled on the skin, as ammonia, potash, or quicklime, then vinegar is the proper substance to employ, followed by washing. Then dry gently. Vaseline or cold cream is usually sufficient as after treatment. Limewater is useful in counteracting the effect of acids spattered in the eye. In the case of alkalies in the eye, the vinegar used should be diluted with three parts of water. Albolene or liquid vaseline is the best agent to drop in the eye after either accident, in order to relieve the irritation and pain, and the patient should stay in a dark room.
FROSTBITE, REAL FREEZING.—Nose, ears, fingers, toes; insensible to touch, stiff, pale or blue. Person may be unconscious.
First Aid Rule 1.—Restore circulation. Rub gently, then vigorously, with snow.
Rule 2.—Restore heat very gradually. Sudden heat is fatal. Keep in cold room, and rub with cloth wet with very cold water till circulation is established. Then rub with equal parts of alcohol and water and expose gradually to heat of living room.
Rule 3.—If person ceases to breathe, resuscitate as if drowned. Open his mouth, grasp his tongue, and pull it forward and keep it there. Let another assistant grasp the arms just below the elbows and draw them steadily upward by the sides of the patient's head to the ground, the hands nearly meeting (which enlarges the capacity of the chest and induces inspiration.) (See pp.30and31.) While this is being done, let a third assistant take position astride the patient's hips with his elbows resting on his own knees, his hands extended ready for action. Next, let the assistant standing at the head turn down the patient's arms to the sides of the body, the assistant holding the tongue changing hands if necessary to let the arms pass. Just before the patient's hands reach the ground the man astride the body will grasp the body with hishands, the ball of the thumb resting on either side of the pit of the stomach, the fingers falling into the grooves between the short ribs. Now, using his knees as a pivot, he will at the moment the patient's hands touch the ground throw (not too suddenly) his whole weight forward on his hands, and at the same time squeeze the waist between them, as if he wished to force something in the chest upward out of the mouth; he will deepen the pressure while he slowly counts one, two, three, four (about five seconds), then suddenly lets go with a final push, which will send him back to his first position. This completes expiration. (A child or a delicate person must be more gently handled.)
At the instant of letting go, the man at the head of the patient will again draw the arms steadily upward to the sides of the patient's head as before (the assistant holding the tongue again changing hands to let the arms pass, if necessary), holding them there while he slowly counts one, two, three, four (about five seconds).
Repeat these movements deliberately and perseveringly twelve or fifteen times in every minute—thus imitating the natural motions of breathing. Continue the artificial respiration from one to four hours, or until the patient breathes; and for a while after the appearance of returning life carefully aid the first short gasps until deepened into full breaths.
Keep body warm after this with warm-water bottles.
FROSTBITE.—The nose, chin, ears, fingers, and toes are the parts usually frozen, although severe results ending in death of the frozen part occur more often owing to low vitality of the patient than to the cold itself. In the milder degree of frostbite there is stiffness, numbness, and tingling of the frozen member; the skin is of a pale, bluish hue and somewhat shrunken. Recovery ensues with burning pain, tingling, redness, swelling and peeling of the epidermis, as after slight burns. The skin is icy cold, white, and insensitive in severe forms of frostbite, and, if not skillfully treated, becomes, later, either swollen and discolored, or shriveled, dry, and black. In either case the frozen part dies and is separated from the living tissue after the establishment of a sharp line of inflammation which results in ulceration and formation of pus, and thus the dead part sloughs off. It is, however, possible for a part thoroughly frozen to regain its vitality.
Treatment.—The essential element in the treatment is to secure a very gradual return of blood to the frozen tissues, and so avoid violent inflammation. To obtain this result the patient should be cared for in a cold room, the frozen parts are rubbed gently with snow, or cloth wet with ice water, until they resume their usual warmth. Then it is well to rub them with a mixture of alcohol and water, equal parts, for a time and expose them to the usual temperature of a dwelling room. Warm drinks are now administered to the patient. Thefrozen member, if hand or foot, is raised high in the air on pillows and covered well with absorbent cotton and bandage. If much redness, swelling, and pain result this dressing is removed and the part is wrapped in a single thickness of cotton cloth kept continually wet with alcohol and water.
Subsequent treatment consists in keeping the damaged parts covered with vaseline or cold cream, absorbent cotton, and bandage. If blisters and sores result, the care is similar to that described for like conditions under burns. If death of the frozen part becomes inevitable, the hand or foot should be suspended in a nearly vertical position to keep the blood out, and the part bathed twice daily with a solution of corrosive sublimate (one 7.7 gr. tablet to pint of water), dusted well with aristol, and dressed with absorbent cotton and bandage until the dead tissue separates and comes away. If the frozen part is large it may be necessary to remove it with a knife, but this is not essential when the tips of the fingers or toes are frozen.
General Effect of Cold.—Sudden exposure to severe cold causes sleep, stupor, and death. Persons found apparently frozen to death should be brought into a cold room, which should be gradually heated, and the body rubbed with snow or ice water, and artificial respiration employed, as just directed. Attempts at resuscitation ought to be persistent, as recoveries have been reported after several hours of unconsciousness and apparent death from freezing.
CHILBLAINS AND MILD FROSTBITES.—The effects of severe cold on the body are very similar to those of intense heat, though they are very much slower in making their appearance. After a person has frozen a finger or toe he may not notice much inconvenience for days, when suddenly violent inflammation may set in. The fingers, ears, nose, and toes are the members which suffer most frequently from the effects of cold. Similar symptoms of inflammation, described under burns, also result from cold, that is, redness and swelling of the skin, blisters with more severe and deeper inflammatory involvement, or, in case the parts are thoroughly frozen, local death and destruction of the tissues. But it is not essential that the body be exposed to the freezing temperature or be frozen at all, in order that some harm may result, for chilblains often follow when the temperature has not been lower than 40° F., or thereabouts.
The effect of cold is to contract the blood vessels, with the production of numbness, pallor, and tingling of the skin. When the cold no longer acts then the blood vessels dilate to more than their usual and normal state, and more or less inflammation results. The more sudden the return to warmth the greater the inflammatory sequel.
Chilblains represent the mildest morbid effect of cold on the body. They exist as bluish-red swellings of the skin, usually on the feet or hands, but may attack the nose or ears, and are attended by burning, itching,and smarting. This condition is caused by dilatation of the vessels following exposure to cold. It is more apt to happen in young, anæmic women. Chilblains usually disappear during warm weather. Scratching, friction, or the severity of the attack may lead to the appearance of blisters and sores. In severe cases the fingers and toes present a sausage-like appearance, owing to swelling.
Treatment.—Susceptible persons should wear thick, warm (not rough) stockings and warm gloves. The chilled members must never be suddenly warmed. Regular exercise and cold shower baths are good to strengthen the circulation, but the feet and hands must be washed in warm water only, and thoroughly dried. If sweating of these parts is a common occurrence, starch or zinc oxide should be dusted on freely night and morning. Cod-liver oil is an efficacious remedy in these cases; one teaspoonful of Peter Möller's pure oil three times daily after meals. The affected parts are bathed twice daily in a solution of zinc acetate (one dram to one pint of water), and followed by the application, on soft linen or cotton, of zinc-oxide ointment containing two per cent of carbolic acid. If this is not curative, iodine ointment mixed with an equal quantity of lard may be tried. Exposure to cold will immediately bring on a recurrence of the trouble. If the affection of the feet is severe the patient must rest in bed. If the parts become blistered and open sores appear, then the same treatment as for burns isindicated. Wash with a weak solution of corrosive sublimate (one tablet for surgical purposes in two quarts of warm water) and apply an ointment of boric acid and vaseline, equal parts, spread on soft, clean cotton or linen. Rest of the part and existence in a warm atmosphere will complete the cure.
INGROWING TOE NAIL.—This is a condition in which the flesh along the edges of the great toe nail becomes inflamed, owing either to overgrowth of the nail or to pressure of the soft parts against it. Improper footgear is the most common cause, as shoes which are too narrow across the toes, or not long enough, or those with high heels which throw the toes forward so that they are compressed by the toe of the boot, especially in walking downhill.
A faulty mode of cutting the toe nails in a healthy foot may favor ingrowing toe nails. Toe nails should be cut straight across, and not trimmed away at the corners to follow the outline of the toes—as then the flesh crowds in at the corners of the nails, and when the nail pushes forward in its growth it presses into the flesh. Nails which have a very rounded surface are more apt to produce trouble, because then the edges are likely to grow down into the flesh. Inflammation in ingrowing toe nail usually arises along the outer edge of the nail. The flesh here becomes red, tender, painful, and swollen so that it overlaps the nail. After a time "matter" or pus forms and finds its way under the nail, and the partsabout it ulcerate, and "proud flesh" or excessive granulation tissue springs up and imbeds the edge of the nail. Wearing a shoe, or walking, becomes impossible. The condition may last for months, or even years, if not rightly treated.
Treatment.—Properly fitting footgear must be worn—broad at the toes with low heels and of sufficient length. If pus ("matter") forms, the cut edge should be raised up by pushing in a little absorbent cotton under the nail every day. Hot poultices of flaxseed meal, or other material will relieve any special pain and inflammation. Soaking the foot frequently in hot water, and observing especial cleanliness, will aid recovery. Tannic acid, or some antiseptic powder like nosophen, should be dusted along the edge of the nail, and the flesh crowded away from the nail by pushing in a little cotton with some tannic acid upon it.
If there is a raw surface about the border of the nail, powdered lead nitrate may be dusted upon it each morning for four or five days, till the ulcerated tissue shrinks away and the edge of the nail becomes visible. The toe should be covered with absorbent cotton and a bandage. As soon as the toe is really inflamed the case becomes surgical, and as such demands the care of a surgeon when one can be obtained.
FAINTING.
First Aid Rule 1.—Remove impediments to respiration. Remove collar, loosen all waist bands andcords, unhook corset or cut the laces at person's back.
Rule 2.—Assist heart and brain with blood pressure. Put cushion under buttocks, wind skirt close about legs, and raise feet in air. Wait ten seconds.
Rule 3.—Aid respiration. Put mild smelling salts under nose. Spatter cold water in face.
SUFFOCATION FROM GAS IN WELLS, CISTERNS, OR MINES, OR FROM ILLUMINATING GAS.
First Aid Rule 1.—Remove quickly into pure air.
Rule 2.—Resuscitate as if drowned. Open his mouth, grasp his tongue, pull it forward and keep it there. Let another assistant grasp the arms just below the elbows, and draw them steadily upward by the sides of the patient's head to the ground, the hands nearly meeting, which enlarges the capacity of the chest and induces inspiration. (See pp.30and31.) While this is being done, let a third assistant take position astride the patient's hips with his elbows resting on his own knees, his hands extended ready for action. Next, let the assistant standing at the head turn down the patient's arms to the sides of his body, the assistant holding the tongue, changing hands if necessary to let the arms pass.
Just before the patient's hands reach the ground, the man astride the body will grasp the body with his hands, the ball of the thumb resting on either side ofthe pit of the stomach, the fingers falling into the grooves between the short ribs. Now, using his knees as a pivot, he will, at the moment the patient's hands touch the ground, throw (not too suddenly) his whole weight forward on his hands, and at the same time squeeze the waist between them, as if he wished to force something in the chest upward out of the mouth; he will deepen the pressure while he slowly counts one, two, three, four (about five seconds), then suddenly lets go with a final push, which will send him back to his first position. This completes expiration. A child or a delicate person must be more gently handled.
At the instant of letting go, the man at the head of the patient will again draw the arms steadily upward, to the sides of the patient's head, as before (the assistant holding the tongue again, changing hands if necessary to let the arms pass, holding them there while he slowly counts one, two, three, four (about five seconds)).
Repeat these movements deliberately and perseveringly twelve or fifteen times in every minute, thus imitating the natural motions of breathing. Continue the artificial respiration from one to four hours, or until the patient breathes; and for a while after the appearance of returning life, carefully aid the first short gasps until deepened into full breaths.
Keep the body warm with hot-water bottles and blanket.
Rule 3.—Give oxygen to breathe from a cylinder,for two days, at short intervals, in the case of illuminating gas.
FIT; CONVULSION.
First Aid Rule 1.—Aid breathing. Loosen collar, waist bands, and unhook corset, or cut the laces behind.
Rule 2.—Protect from injury. Gently restrain from falling or rolling against furniture; lay flat on bed.
Rule 3.—Protect tongue from being bitten. Open jaws and put between teeth rubber eraser tied to stout string, or rubber stopper tied to stout string.
Rule 4.—Crush pearl of amyl nitrite in handkerchief, and hold close to patient's nose and mouth, till face is red and patient relaxes.
Rule 5.—Let patient sleep after fit without rousing.

Scarlet Fever—Symptoms and Treatment—Precautions Necessary—Measles—Communicating the Disease—Smallpox—Vaccination—How to Diagnose Chickenpox.
ERUPTIVE CONTAGIOUS FEVERS(including Scarlet Fever, Measles, German Measles, Smallpox, and Chickenpox).—These, with the exception of smallpox, attack children more commonly than adults. As they all begin with fever, and the characteristic rash does not appear for from one to four days after the beginning of the sickness, the diagnosis of these diseases must always be at the onset a matter of doubt. For this reason it is wise to keep any child with a fever isolated, even if the trouble seems to be due to "a cold" or to digestive disturbance, to avoid possible communication of the disorder to other children. While colds and indigestion are among the most frequent ailments of children, they must not be neglected, for measles begins as a bad cold, smallpox like thegrippe, and scarlet fever with a sore throat or tonsilitis, and vomiting.
By isolation is meant that the sick child should stay in a room by himself, and the doors should be keptclosed and no children should enter, nor should any objects in the room be removed to other parts of the house after the beginning of its occupation by the patient.
The services of a physician are particularly desirable in all these diseases, in order that an early diagnosis be made and measures be taken to protect the family, neighbors, and community from contagion. The failure of parents or guardians to secure medical aid for children is regarded by the law as criminal neglect, and is subject to punishment. Boards of health require the reporting of all contagious diseases as soon as their presence is known, and failure to comply with their rules also renders the offender liable to fine or imprisonment in most places.
SCARLET FEVER(Scarlatina).—There is no difference between scarlet fever and scarlatina. It is a popular mistake that the latter is a mild type of scarlet fever. Fever, sore throat, and a bright-red rash are the characteristics of this disease. It occurs most frequently in children between the ages of two and six years. It is practically unknown under one year of age. Prof. H. M. Biggs, of the New York Department of Health, has seen but two undoubted cases in infants under twelve months. It is rare in adults, and one attack usually protects the patient from another. Second attacks have occurred, but many such are more apparent than real, since an error in diagnosis is not uncommon. The disease is communicated chiefly by means of the scales of skin which escape during the peeling process, but may also be acquired at any time from the onset of the attack from the breath, urine, and discharges from the body; or from substances which have come in contact with these emanations. Scarlet fever is probably a germ disease, and the germs may live for weeks in toys, books, letters, clothing, wall paper, etc. Close contact with the patient, or with objects which have come in close touch with the patient, is apparently necessary for contagion.
Period of Development.—After exposure to the germs of scarlet fever, usually from two to five days elapse before the disease shows itself. Occasionally the outbreak of the disease occurs within twenty-four hours of exposure, and rarely is delayed for a week or ten days.
Symptoms.—The onset is usually sudden. It begins with vomiting (in very young children sometimes convulsions), sore throat, fever, chilliness, and headache. The tongue is furred. The patient is often stupid; or may be restless and delirious. Within twenty-four hours or so the rash appears—first on the neck, chest, or lower part of back—and rapidly spreads over the trunk, and by the end of forty-eight hours covers the legs and entire body excepting the face, which may be simply flushed. The rash appears as fine, scarlet pin points scattered over a background of flushed skin. At its fullest development, at the end of the second or third day, the whole body may presentthe color of a boiled lobster. After this time the rash generally fades away and disappears within five to seven days. It is likely to vary much in intensity while it lasts. As the rash fades, scaling of the skin begins in large flakes and continues from ten days to as many weeks, usually terminating by the end of the sixth to eighth week. One of the notable features is the appearance of the tongue, at first showing red points through a white coating, and after this has cleared away, in presenting a raspberry-like aspect. The throat is generally deep red, and the tonsils may be dotted over with white spots (see Tonsilitis) or covered with a whitish or gray membrane suggesting diphtheria, which occasionally complicates scarlet fever. The fever usually is high (103° to 107° F), and the pulse ranges from 120 to 150; both declining after the rash is fully developed, generally by the fourth day. The urine is scanty and dark. There is, however, great variation in the symptoms as to their presence or absence, intensity, and time of occurrence and disappearance.
Complications and Sequels.—These are frequent and make scarlet fever the most dreaded of the eruptive diseases, except smallpox. Enlarged glands under the jaw and at the sides of the neck are common, and appear as lumps in these sites. Usually not serious, they may enlarge and threaten life. Pain and swelling in the joints, especially of the elbows and knees, are not rare, and may be the precursors of serious inflammation of these parts. One of the most frequent and serious complications of scarlet fever is inflammation of the kidneys, occurring more often toward the end of the second week of the disease. Examination of the urine by the attending physician at frequent intervals throughout the course of the disorder is essential, although puffiness of the eyelids and face, and of the feet, ankles, and hands, together with lessened secretion of urine—which often becomes of a dark and smoky hue—may denote the onset of this complication. The disease of the kidneys usually results in recovery, but occasionally in death or in chronic Bright's disease of these organs. Inflammation of the middle ear with abscess, discharge of matter from the ear externally, and—as the final outcome—deafness, is not uncommon. This complication may be prevented to a considerable extent by spraying the nose and throat frequently and by the patient's use of a nightcap with earlaps, if the room is not sufficiently warm. Inflammation of the eyelids is an occasional complication. The heart is sometimes attacked by the toxins of the disease, and permanent damage to the organ, in the form of valvular trouble, may result. Blindness and nervous disorders are among the rarer sequels including paralyses and St. Vitus's dance.
Determination of Scarlet Fever.—When beginning with vomiting, headache, high fever, and sore throat, and followed in twenty-four hours with a general scarlet rash, this is not difficult; but occasionallyother diseases present rashes, as indigestion,grippe, and German measles, which puzzle the most acute physicians. Measles may be distinguished from scarlet fever in that measles appears first on the face, the rash is patchy or blotchy, and does not show for three to four days after the beginning of the sickness. The patient seems to have a bad cold, with cough, running at the nose, and sore eyes. German measles is mild, and while the rash may look something like that of scarlet fever, the patient does not seem generally ill, is hardly affected at all, though rarely troubled with slight catarrh of the nose. In no sickness are the services of a physician more necessary than in scarlet fever; first, to determine the existence of the disease, and then to prevent or combat the complications which often approach insidiously.
Outlook.—The average death rate of scarlet fever is about ten per cent. It is very fatal in children about a year old, and most of the deaths occur in those under the age of six. But the mortality varies greatly at different times and in different epidemics. In 1904–5, in many parts of the United States, the disease was very prevalent and correspondingly mild, and deaths were rare.
Duration of Contagion.—The disease is commonly considered contagious only so long as peeling of the skin lasts. But it seems probable that any catarrhal secretion from the nose, throat, or ear is capable of communicating the germs from a patient to anotherperson for many days after other evidences of the disease are past. Scarlet fever patients should always be isolated for as long a period as six weeks—and better eight weeks—without regard to any shorter duration of peeling, and if peeling continues longer, so should the isolation.
Treatment.—In case a physician is unobtainable the patient must be put to bed in the most airy, sunshiny room, which should be heated to 70° F., and from which all the unnecessary movables should be taken out before the entrance of the patient. A flannel nightgown and light bed clothing are desirable. The fever is best overcome by cold sponging, which at the same time diminishes the nervous symptoms, such as restlessness and delirium. The body is sponged—part at a time—with water at the temperature of about 70° F., after placing a single thickness of old cotton or linen wet with ice or cold water (better an ice cap) over the forehead. The part is thoroughly dried as soon as sponged, and the process is repeated whenever the temperature is over 103° F. There need be no fear that the patient may catch cold if only a portion of the body is exposed at any one time. If there is any chilliness following sponging, a bag or bottle containing hot water may be placed at the feet. It is well that a rubber bag containing ice, or failing this a cold cloth, be kept continually on the head while fever lasts. The throat should be sprayed hourly with a solution of hydrogen peroxide (full strength) and the nose withthe same, diluted with an equal amount of water, three times a day. The outside of the throat it is wise to surround with an ice bag, or lacking this, a cold cloth frequently wet and covered with a piece of oil silk (or rubber) and flannel.
The diet should consist of milk, broths, or thin gruels, and plenty of water should be allowed. Sweet oil or carbolized vaseline should be rubbed over the whole body night and morning during the entire sickness and convalescence. The bowels must be kept regular by injections or mild cathartics, and, after the fever subsides, vegetables, fruit, cereals, and milk may be permitted, together with meat or eggs once daily. It is imperative for the nurse and also the mother to wear a gown and cap over the outside clothes, to be slipped off in the hall at the door of the sick room when leaving the latter.
MEASLES.—Measles is a contagious disease, characterized by a preliminary stage of fever and catarrh of the eyes, nose, and throat, and followed by a general eruption on the skin. One attack practically protects a person from another, yet, on the other hand, second attacks occur with extreme rarity. It is more contagious than scarlet fever, and isolation of a patient in a house is of less service in preventing communication to other inmates, whereas in scarlet fever half the number of susceptible children may escape the disease through this precaution. The germs which cause measles perish rapidly, so that infected clothesor other objects merely require a thorough airing to be rendered safe, whereas in scarlet fever the danger of transmission of the contagion may lurk in infected clothing and other substances for weeks, unless they are subjected to proper disinfection. A patient with measles is capable of communicating the disorder from its onset, before the appearance of the rash, through the breath, discharges from the nose and eyes, tears and saliva and all the secretions. At the end of the third week of the disease the patient is usually incapable of giving the disease to others. Close contact with a patient is commonly necessary for one to acquire the disease, but it is frequently claimed that it is carried by a third person in the clothes, as by a nurse. It is infrequent in infants under six months, and most frequent between the second and sixth year. Adults are attacked by measles more often than by scarlet fever.
Development.—A period of from seven to sixteen days after exposure to measles elapses before the disease becomes apparent.
Symptoms.—The disease begins like a severe nasal catarrh with fever. The eyes are red and watery, the nose runs, and the throat is irritable, red, and sore, and there is some cough, with chilliness and muscular soreness. The fever, higher at night, varies from 102° to 104° F., and the pulse ranges from 100 to 120. There is often marked drowsiness for a day or two before the rash appears. Coated tongue, loss of appetite, occasional vomiting, and thirst are present during this period. The appearance of minute, whitish spots, surrounded by a red zone, may often be seen in the inside of the mouth opposite the back teeth for some days before the eruption occurs.
The preliminary period, when the patient seems to be suffering with a bad cold, lasts for four days usually, and on the evening of the fourth day the rash breaks out. It first appears on the face and then spreads to the chest, trunk, and limbs. Two days are generally required for the complete development of the rash; it remains thus in full bloom for about two days more, then begins to subside, fading completely in another two days—six days in all.
The rash appears as bright-red, slightly raised blotches on the face, which is generally somewhat swollen. The same rash extends to the abdomen, back, and limbs. Between the mottled, red rash may be seen the natural color of the skin. At this time the cough may be hoarse and incessant, and the eyes extremely sensitive to light. The fever and other symptoms abate when the rash subsides, and well-marked scaling of the skin occurs.
Complications and Sequels.—Severe bronchitis, pneumonia, croup, laryngitis, sore eyes, ear abscess and deafness, violent diarrhea, convulsions, and, as a late result, consumption sometimes accompany or follow measles. For the consideration of these disorders, see special articles in other parts of this work.
Outlook.—The vast majority of healthy patients over two years old recover from measles completely. Younger children, or those suffering from other diseases, may die through some of the complications affecting the lungs. The disease is peculiarly fatal in some epidemics occurring among those living in unhygienic surroundings, and in communities unaccustomed to the ravages of measles. Thus, in an epidemic attacking the Fiji Islanders, over one-quarter of the whole population (150,000) died of measles in 1875. Measles is more severe in adults than in children.
Diagnosis.—For one not familiar with the characteristic rash a written description of it will not suffice for the certain recognition of the disease, but if the long preliminary period of catarrh and fever, and the appearance of the eruption on the fourth day, be taken into account—together with the existence of sore eyes and hoarse, hard cough—the determination of the presence of measles will not be difficult in most cases.
Treatment.—The patient should be put to bed in a darkened, well-ventilated room at a temperature of 68° to 70° F. While by isolation of the patient we may often fail to prevent the occurrence of measles in other susceptible persons in the same house, because of the very infectious character of the disease, and because it is probable that they have already been exposed during the early stages when measles was not suspected, yet all possible precautions should be adopted promptly. For this reason other children in the house should bekept from school and away from their companions, and they ought not to be sent away from home to spread the disease elsewhere. The bowels should be kept regular by soapsuds injections or by mild cathartics, as a Seidlitz powder. If the fever is over 103° F. and is accompanied by much distress and restlessness, children may be sponged with tepid water, and adults with water at 80° F., every two hours or so as directed under scarlet fever. When cough is incessant or the rash does not come out well, there is nothing better than the hot pack.
The patient is stripped and wrapped from feet to neck in a blanket wrung out of hot water containing two teaspoonfuls of mustard stirred into a gallon of water. This is then covered with two dry blankets and the patient allowed to remain in the blankets for two or three hours, when the application may be repeated. It is well to keep a cold cloth on the head during the process. Cough is also relieved by a mixture containing syrup of ipecac, twenty drops; paregoric, one teaspoonful, for an adult (or one-third the dose for a child of six), which should be given in one-quarter glass of water and may be repeated every two hours. If there is hoarseness, the neck should be rubbed with a mixture of sweet oil, two parts; and oil of turpentine, one part, and covered with a flannel bandage. The cough mixture will tend to relieve this condition also. A solution of boric acid (ten grains of boric acid to the ounce ofwater) is to be dropped in both eyes every two hours with a medicine dropper. Although usually mild, the eye symptoms may be very severe and require special treatment, and considerably impaired vision may be the ultimate result. Severe diarrhea is combated with bismuth subnitrate, one-quarter teaspoonful, every three hours. For adults, the diet consists of milk, broths, gruels, and raw eggs. Young children living on milk mixtures should receive the mixture to which they are accustomed, diluted one-half with barley water. Nourishment must be given every two hours except during sleep. The patient should be ten days in bed, and should remain three days in his room after getting up (or three weeks in all, if there are others who may contract measles in the house), and after leaving his room should stay in the house a week longer. The principal danger after an attack of measles is of lung trouble—pneumonia or tuberculosis (consumption)—and the greatest care should be exercised to avoid exposure to the wet or to cold draughts.
GERMAN MEASLES(Rötheln).—German measles is related neither to measles nor scarlet fever, but resembles them both to a certain extent—more closely the former in most cases. It is a distinct disease, and persons who have had both measles and scarlet fever are still susceptible to German measles. One attack of German measles usually protects the patient from another. Adults, who have not been previously attacked, are almost as liable to German measles as children, butit is rare that infants acquire the disease. It is a very contagious disorder—but not so much so as true measles—and often occurs in widespread epidemics. The breath and emanations from the skin transmit thecontagiumfrom the appearance of the first symptom to the disappearance of the eruption.
Development.—The period elapsing after exposure to German measles and before the appearance of the symptoms varies greatly—usually about two weeks; it may vary from five to eighteen days.
Symptoms.—The rash may be the first sign of the disease and more frequently is so in children. In others, for a day or two preceding the eruption, there may be headache, soreness, and redness of the throat, the appearance of red spots on the upper surface of the back of the mouth, chilliness, soreness in the muscles, loss of appetite, watering of the eyes. Catarrhal symptoms are most generally absent, an important point in diagnosis. When present, they are always mild. These preliminary symptoms, if present, are much milder and of shorter duration than in measles, where they last for four days before the rash appears; and the hard, persistent cough of measles is absent in German measles. Also, while there is sore throat in the latter, there is not the severe form with swollen tonsils covered with white spots so often seen in scarlet fever. Fever is sometimes absent in German measles; usually it ranges about 100° F., rarely over 102° F. Thus, German measles differs markedly from both scarletfever and measles proper. The rash usually appears first on the face, then on the chest, and finally covers the whole body, in the space of a few hours—twenty-four hours at most. The eruption takes the form of rose-red, round or oval, slightly raised spots—from the size of a pin head to that of a pea—sometimes running together into uniform redness, as in scarlet fever. The rash remains fully developed for about two days, and often changes into a coppery hue as it gradually fades away. There are often lumps—enlarged glands—to be felt under the jaw, on the sides and back of the neck, which occur more commonly in German than in true measles. The glands at the back of the neck are the most characteristic. They are enlarged in about two-thirds of the cases.
Determination.—The diagnosis or determination of the existence of measles must be made, in the absence of a physician, on the general symptoms rather than on the rash, which requires experience for its recognition and is subject to great variations in appearance, at one time simulating measles, at another scarlet fever.
German measles differs from true measles in the following points: the preliminary period—before the rash—is mild, short, or absent; fever is mild or absent; the cold in the nose and eyes and cough are slight or may be absent, as contrasted with these symptoms in measles, while the enlarged glands in the neck are more pronounced than in measles. The onset of Germanmeasles is not so sudden as in scarlet fever and not accompanied with vomiting as in the latter, while the sore throat and fever are much milder in German measles. The peeling, which is so prominent in scarlet fever with the disappearance of the rash, is not infrequently present. It may be absent. Its presence or absence seems to depend upon the severity of the eruption. The desquamation when present is finer than in either measles or scarlet fever.
Outlook.—Recovery from German measles is the invariable rule, and without complications or delay.
Treatment.—Little or no treatment is required. The patient should remain in bed in a darkened room on a liquid diet while fever lasts, and be isolated from others indoors until all signs of the eruption are passed. The eyes should be treated with boric acid as in measles; the diet, during the fever, consisting of milk, broths, thin cereals, beef juice, raw eggs or eggnog, for adults and older children; while infants should have their milk mixture diluted one-half with barley water. A bath and fresh clothing for the patient, and thorough cleansing and airing of the sick room and clothing are usually sufficient after the passing of the disease without chemical disinfection.
SMALLPOX.—Smallpox is one of the most contagious diseases known. It is extremely rare for anyone exposed to the disease to escape its onslaught unless previously protected by vaccination or by a former attack of the disease. One is absolutely safe fromacquiring smallpox if recently and successfully vaccinated, and thus has one of the most frightful and fatal scourges to which mankind has ever been subject been robbed of its dangers. Thecontagiumis probably derived entirely from the scales and particles of skin escaping from smallpox patients, and in the year 1905–6 the true germ of the disease was discovered by Councilman, of Boston. It is not necessary to come in direct contact with a patient to contract the disease, as thecontagiummay be transmitted some little distance through the air, possibly even outside of the sick room. One attack almost invariably protects against another. All ages are liable to smallpox; it is particularly fatal in young children, and during certain epidemics has proved more so in colored than in white people.
Development.—A period of ten or twelve days usually elapses after exposure to smallpox before the appearance of the first symptoms of the disease. This period may vary, however, from nine to fifteen days.
Symptoms.—There is a preliminary period of from twenty-four to forty-eight hours after the beginning of the disease before an eruption occurs. The onset is ushered in by a set of symptoms simulating those seen in severegrippe, for which smallpox is often mistaken at this time. The patient is suddenly seized with a chill, severe pains in the head, back, and limbs, loss of appetite and vomiting, dizziness on sitting up, and fever—103° to 105° F. In young children convulsions often take the place of the chill seen in adults. On the second day a rash often appears on the lower part of the belly, thighs, and armpits, which may resemble that characteristic of measles or scarlet fever, but does not last for over a day or two. It is very evanescent and, consequently, rarely seen. Diarrhea often occurs, as well as vomiting, particularly in children. On the evening of the fourth day the true eruption usually appears; first on the forehead or face, and then on the arms, hands, and legs, palms, and soles. The eruption takes successively four forms: first, red, feeling like hard pimples or like shot; then, on the second or third day of the eruption, these pimples become tipped with little blisters with depressed centers, and surrounded by a red blush. Two or three days later the blisters are filled with "matter" or pus and present a yellowish appearance and are rounded on top. Finally, on about the tenth day of the eruption, the pustules dry up and the matter exudes, forming large, yellowish or brownish crusts, which, after a while, drop off and leave red marks and, in severe cases, pitting. The fever preceding the eruption often disappears upon the appearance of the latter and in mild cases does not reappear, but in severe forms the temperature remains about 100° F., and when the eruption is at its height again mounts to 103° to 105° F., and gradually falls with convalescence. The eruption is most marked on the face, hands, and forearms, and occurs less thickly on the body. It appears also in the mouth and throat andwhen fully developed on the face gives rise to pain and considerable swelling and distortion of the features, so that the eyes are closed and the patient becomes frightfully disfigured and well-nigh unrecognizable. Delirium is common at this time, and patients need constant watching to prevent their escape from bed. In the severe forms the separate eruptive points run together so that the face and hands present one distorted mass of soreness, swelling, and crusting. In these, pitting invariably follows, while in those cases where the eruption remains distinct, pitting is not certain to occur. A still worse form is that styled "black smallpox," in which the skin becomes of a dark-purplish hue, from the fact that each pustule is a small blood blister, and bleeding occurs from the nose, mouth, etc. These cases are almost, without exception, fatal in five to six days.
The patient may say that the eruption was the first symptom he observed. This was particularly noticed in negroes, many of whom had never been vaccinated. The eruption may exhibit but a dozen or so points, especially about the forehead, wrists, palms, and soles. After the first four days the fever and all the disagreeable symptoms may subside, and the patient may feel absolutely well. The eruption, however, passes through the stages mentioned, although but half the time may be occupied by the changes; five or six days instead of ten to twelve for crusts to form. In such cases the death rate has been exceedingly low, although it is perfectly possible for a person to contract the most severe smallpox from one of these mild (and often unrecognized) cases, as has unfortunately happened. Smallpox occurring after successful vaccination resembles, in its characteristics, the cases just described, and unless vaccination had been done many years previously, the results are almost always favorable as regards life and absence of pitting.
Detection.—Smallpox is often mistaken for chickenpox, or some of the skin diseases, in its mild forms. The reader is referred to the article on chickenpox for a consideration of this matter. The mild type should be treated just as rigidly as severe cases with regard to isolation and quarantine, being more dangerous to the community because lightly judged and not stimulating to the adoption of necessary precautions. The preliminary fever and other symptoms peculiar to smallpox will generally serve to determine the true nature of the disease, since these do not occur in simple eruptions on the skin. The general symptoms and course of smallpox must guide the layman rather than the appearance of the eruption, which requires educated skill and experience to recognize. Chickenpox in an adult is less common than in children. Smallpox is very rare in one who has suffered from a previous attack of the disease or in one who has been successfully vaccinated within a few years.
Outlook.—The death rate of smallpox in those who have been previously vaccinated at a comparatively recent date, or in varioloid, as it is called when thus modified by vaccination, is only 1.2 per cent. There are, however, severe cases following vaccinations done many years previous to the attack of smallpox. While these cannot be called varioloid, yet the death rate is much lower than in smallpox occurring in the unvaccinated. Thus, before the mild epidemic of 1894 the death rate in the vaccinated was sixteen per cent; since 1894 it has been only seven per cent; while in the unvaccinated before 1894 it was fifty-eight per cent; and since that date it has been but seventeen per cent, as reported by Welch from the statistics of 5,000 cases in the Philadelphia Municipal Hospital.
Complications.—While a variety of disorders may follow in the course of smallpox, complications are not very frequent in even severe cases. Inflammation of the eyelids is very common, however, and also boils in the later stages. Delirium and convulsions in children are also frequent, as well as diarrhea; but these may almost be regarded as natural accompaniments of the disease. Among the less common complications are: laryngitis, pneumonia, diseases of the heart, insanity, paralysis, various skin eruptions, inflammation of the joints and of the eyes and ears, and baldness.
Treatment.—Prevention is of greatest importance. Vaccination stands alone as the most effective preventive measure in smallpox, and as such has no rival in the whole domain of medicine. The modern method includes the inoculation of a human being with mattertaken from one of the eruptive points on the body of a calf suffering with cowpox. Whether cowpox is a modified form of smallpox or a distinct disease is unknown.
The period of protection afforded by a successful vaccination is uncertain, because it varies with different individuals. In a general way immunity for about four or five years is thus secured; ten or twelve years after vaccination the protection is certainly lost and smallpox may be then acquired. Every individual should be vaccinated between the second and third month after birth, and between the ages of ten and twelve, and at other times whenever an epidemic threatens. An unvaccinated person should be vaccinated and revaccinated, until the result is successful, as immunity to vaccination in an unvaccinated person is practically unknown. When unsuccessful, the vaccine matter or the technique is faulty. A person continuously exposed to smallpox should be vaccinated every few weeks—if unsuccessful, no harm or suffering follow; if successful, it proves liability to smallpox. A person previously vaccinated successfully may "take" again at any time after four or five years, and, in event of possible exposure to smallpox, should be revaccinated several times within a few weeks—if the vaccination does not "take"—before the attempt is given up. An unvaccinated person, who has been exposed to smallpox, can often escape the disease if successfully vaccinated withinthree days from the date of the exposure, but is not sure to do so.
Diseases are not introduced with vaccination now that the vaccine matter is taken from calves and not from the human being, as formerly. Most of the trouble and inflammation of the vaccinated part following vaccination may be avoided by cleanliness and proper care in vaccinating.
In the absence of a physician, vaccination may be properly done by any intelligent person when the circumstances demand it. Vaccination is usually performed upon the outside of the arm, a few inches below the shoulder, in the depression situated in that region. If done on the leg, the vaccination is apt to be much more troublesome and may confine the patient to bed. The arm should be thoroughly washed in soap and warm water, from shoulder to elbow, and then in alcohol diluted one-third with water. When this has evaporated (without rubbing), the dry arm is scratched lightly with a cold needle which has previously been held in a flame and its point heated red hot. The point must thereafter not be touched with anything until the skin is scratched with it. The object is not to draw blood, but to remove the outer layer of skin, over an area about one-fourth of an inch square, so that it appears red and moist but not bleeding. This is accomplished by very light scratching in various directions. Another spot, about an inch or two below, may be similarly treated. Then vaccine matter, ifliquid, is squirted on the raw spots, or, if dried on points, the ivory point is dipped in water which has been boiled and cooled, and rubbed thoroughly over the raw places. The arm must remain bare and the vaccination mark untouched until the surface of the raw spot is perfectly dry, which may take half an hour. A piece of sterilized surgical gauze, reaching halfway about the arm and kept in place with strips of adhesive plaster (or an absolutely clean handkerchief bound about the arm, and held by sewing or safety pins), ought to cover the vaccination for three days. After this time the sore must only come in contact with soft and clean old cotton or linen, which may be daily pinned in the sleeve of the under garment. If the scab is knocked off and an open sore results it should be treated like any wound.
If the vaccination "takes," it passes through several stages. On the third day following vaccination a red pimple forms at the point of introduction of the matter, which is surrounded by a circle of redness. Some little fever may occur. On the fifth day a blister or pimple containing clear fluid with a depressed center is seen, and a certain amount of hard swelling, itchiness, and pain is present about the vaccination. A sore lump (gland) is often felt under the arm. The full development is reached by the eighth day, when the pimple is full and rounded and contains "matter," and is surrounded by a large area of redness. From the eleventh day the vaccination soredries, and a brown scab forms over it about the end of the fourteenth day, and the redness and swelling gradually depart. At the end of about three weeks the scab drops off, leaving a pitted scar or mark. Not infrequently the vaccination results in a very slight pimple and redness, which passes through the various stages described, in a week or ten days, in which case the vaccination should be repeated. Unless the vaccination follows very closely the course described, it cannot be regarded as successful, although after the first one or two vaccinations the result is often not so severe, and the time of completion of the various stages somewhat shortened.
Rarely an eruption, resembling that at the vaccination site, appears on the vaccinated limb and even becomes general upon the body, due to urticaria or to inoculation, through scratching.
The special treatment of an attack of smallpox is largely a matter of careful nursing. A physician or nurse can scarcely lay claim to any great degree of heroism in caring for smallpox patients, as there is no danger of contracting the disease providing a successful vaccination has been recently performed upon them. The patient should be quarantined in an isolated building, and all unnecessary articles should be removed from the sick room, in the way of carpets and other furnishings. It is well that the room be darkened to save irritation of the eyes. The diet should be liquid: milk, broths, and gruels. Laudanum, fifteen drops, or paregoric, one tablespoonful in water, may be given to adults, once in three hours, to relieve pain during the first few days. Sponging throughout the course of the disease is essential; first, with cool water, as directed for scarlet fever, with the use of cold on the head to relieve the itching, fever, and delirium. The cold pack is still more efficient. To give this, the patient is wrapped in a sheet wrung out in water at a temperature between 68° and 75° F. The sheet surrounds the naked body from feet to neck, and is tucked between the legs and between the body and arms; the whole is then covered with a dry blanket, and a cold, wet cloth or ice cap is placed upon the head. The patient may be permitted to remain in the pack for an hour, when it may be renewed, if necessary, to allay fever and restlessness; otherwise it may be discontinued. The cold sponging or cold pack are indicated when the temperature is over 102.5° F., and when with fever there are restlessness and delirium. Great cleanliness is important throughout the disease; the bedclothes should be changed daily and the patient sponged two or three times daily with warm water, unless fever is high. Cloths wet with cold carbolic-acid solution (one-half teaspoonful to the pint of hot water) should be kept continuously on the face and hands. Holes are cut in the face mask for the eyes, nose, and mouth, and the whole covered with a similar piece of oil silk to keep in the moisture. Such applications give muchrelief, and to some extent prevent pitting. The hair must be cut short, and crusts on the scalp treated with frequent sponging and applications of carbolized vaseline, to soften them and hasten their falling. The boric-acid solution should be dropped into the eyes as recommended for measles, and the throat sprayed every few hours with Dobell's solution. Diarrhea in adults may be checked with teaspoonful doses of paregoric given hourly in water. Vaseline and cloths used on a patient must not be employed on another, as boils are thus readily propagated. All clothing, dishes, etc., coming in contact with a patient must be boiled, or soaked in a two-per cent carbolic-acid solution for twenty-four hours, or burned. When the patient is entirely free from scabs, after bathing and putting on disinfected or new clothes outside of the sick room, he is fit to reënter the world.
CHICKENPOX.—Chickenpox is a contagious disease, chiefly attacking children. While it resembles smallpox in some respects, at times simulating the latter so closely as to puzzle physicians, it is a distinct disease and is in no way related to smallpox. This is shown by the fact that chickenpox sometimes attacks a patient suffering with, or recovering from, smallpox. Neither do vaccination nor a previous attack of smallpox protect an individual from chickenpox. Chickenpox is not common in adults, and its apparent presence in a grown person should awaken the liveliest suspicion lest the case be one of smallpox,since this mistake has been frequently made, and with disastrous results, during an epidemic of mild smallpox. One attack of chickenpox usually protects against another, but two or three attacks in the same individual are not unknown. The disease may be transmitted from the patient to another person from the time of the first symptom until the disappearance of the eruption. The disease ordinarily occurs in epidemics, but occasionally in isolated cases.
Development.—A period of two weeks commonly elapses after exposure to the disease before the appearance of the first symptom of chickenpox, but this period may vary from thirteen to twenty-one days.
Symptoms.—The characteristic eruption is often the first warning of chickenpox, but in some cases there may be a preliminary period of discomfort, lasting for a few hours, before the appearance of the rash; particularly in adults, in whom the premonitory symptoms may be quite severe. Thus, there may be chilliness, nausea, and even vomiting, rarely convulsions in infants, pain in the head and limbs, and slight fever (99° to 102° F.) at this time. The eruption shows first on the body, in most cases, especially the back. It consists of small red pimples, which rapidly develop into pearly looking blisters about as large as a pea to that of the finger nail, and are sometimes surrounded by a red blush on the skin. These blisters vary in number, from a dozen or so to two hundred. They do not run together, and in three to four days dry up, become shriveled and puckered, and covered with a dark-brown or blackish crust, and drop off, leaving only temporary red spots in most cases. The fever usually continues during the eruption. During the first few days successive fresh crops of fresh pimples and blisters appear, so that while the first crop is drying the next may be in full development. This forms one of its distinguishing features when chickenpox is compared with smallpox. In chickenpox the eruption is seen on the unexposed skin chiefly, but may occur on the scalp and forehead, and even on the palms, soles, forearms, and face. In many cases the eruption is found in the mouth, on its roof, and the inside of the cheeks. The blisters rarely contain "matter" or pus, as in smallpox, unless they are scratched. Scratching may lead to the formation of ugly scars and should be prevented, especially when the eruption is on the face. Pitting rarely occurs.
Determination.—The discrimination between chickenpox and smallpox is sometimes extremely puzzling and demands the skill of an experienced physician. When one is unavailable, the following points may serve to distinguish the two disorders: smallpox usually begins like a severe attack ofgrippe, with pain in the back and head, general pains and nausea or vomiting, with high fever (103° to 104° F.) These last two or three days, and may completely subside when the rash appears. In chickenpox preliminary discomfort is absent, or lasts but a few hours beforethe eruption. The eruption of smallpox usually occurs first on the forehead, near the hair, or on the palms of the hands, soles of the feet, the arms and legs, but is usually sparse on the body. The eruption appears about the same time in smallpox and not in successive crops, as in chickenpox. Chickenpox is more commonly a disease of childhood; smallpox attacks all ages. The crusts in chickenpox are thin, and appear in four or five days, while those of smallpox are large and yellow, and occur after ten or twelve days.
