GENERAL REMARKS ON TREATMENT
The guiding principles in the treatment of diseases of the skin differ in no respect from those which govern in the management of maladies of other organs. A correct diagnosis is essential except in diseases running an acute course, which get well in spite of the bungling often consequent upon error; but such affections are not very common in dermatologic practice, and usually a sine qua non to success is first to know what the disease is.
The proper diagnosis in its relation to therapeutics does not con sist, however, in merely, naming the disease correctly, but also includes an appreciation, so far as possible, of the etiologic and pathologic factors in the case. Thus founded, treatment will be most promising as to results, especially as to permanency. It is true, in most instances, that it is not always possible to discover the true etiologic influences, and to a great extent, therefore, the therapeutic management is often that which practical experience has proved of service.
A cure, if possible, should be brought about as quickly as practicable. The belief of the laity that impurities are trying to get out, and that it is, therefore, dangerous to the general health to cure or to cure too rapidly, and which formerly found honest believers among physicians, is wholly without foundation. This view has been strongly supported pur posely by advertising nostrums, and has likewise been a convenient cloak for medical advisers helplessly at sea in cutaneous therapeutics. On the contrary, the putting of the skin, an important organ and emunc- tory of the body, into a healthy state, will not only relieve the patient of an annoyance and worry, but conduce to his general well-being.1 The main difficulty, unfortunately, in many diseases is our inability to cure quickly enough.
In most diseases both local and constitutional measures are required. There is some diversity as regards the value of internal medication, which in times remote held the prominent place in treatment, but which was gradually displaced by those holding the opinion that skin diseases are purely local maladies, with no relationship to the general organism, and therefore manageable by purely external measures—a view which reached its greatest prevalence under the late Professor Hebra, and is still held to a greater or less extent by most of the German writers, the French, English, and Americans taking a conservative middle ground. The strongest support of this latter view is found in the fact that many American specialists, as well as many in England, spent a few years under the distinguished tutelage of Hebra, Neumann, and Kaposi, whose

views as to local treatment practically coincided, and returned home thoroughly imbued with this idea, but which, under the test of in creasing personal experience, has gradually given place to the opinion that while external remedies are essential in almost all cases, the proper constitutional management in many diseases is likewise important, and that the maintenance of good health keeps up the tissue-resisting power, and therefore is of potent influence in the permanency of cure in cuta neous as well as other diseases.1 It is true that many affections are purely local, often parasitic, and that, therefore, systemic measures are scarcely called for, but in some of these, doubtless, cutaneous tissue weakness, induced by general ill health due to constitutional or organic disease, favors successful parasitic invasion, and therefore systemic in vigorating measures are sometimes of service. This is often demon strated also in pulmonary tuberculosis. The various therapeutic meas ures and special remedies, both local and constitutional, will be referred to, more at length, in connection with the individual diseases. A brief preliminary review of the underlying principles and of some of the chief remedies, may, however, be of some service.
CONSTITUTIONAL TREATMENT
For the most part, in the general constitutional management of those diseases of the skin in which this seems advisable, it is not so much to be based upon the malady present as it is upon the patient —in short, the individual is to be studied rather than the skin disease with which he is afflicted, and in the general run of cases much more is to be expected than if remedies with alleged direct specific action upon the malady or the cutaneous tissues are depended upon. Such remedies, though relatively few in number, are not, however, com pletely to be ignored, for they sometimes have a decidedly useful in fluence. As remarked in discussing the physiology of the skin, it is to be considered as one of the four emunctories of the body, and when this is diseased or its full usefulness compromised, the functional deficiency is partly, sometimes completely, made up by compensatory activity of the other three, more especially, however, the kidneys and intestinal tract; and, conversely, impairment of one of the latter may indirectly, or possibly directly, be influential in provoking cutaneous disorders, as referred to under general etiology, either by the superinduced increased activity, or, and more probably, by the action of certain excretory products which ordinarily should find their outlet through the kidneys or intestinal tract. This possibility is to be borne in mind in the treat ment. Very often in the management, increased activity of the kidneys and intestinal tract, by remedies which increase the flow of urine, and promote free movement of the bowels, has a material influence in lessen ing and modifying cutaneous disturbances, particularly those of an in-
1 Duhring, “Treatment of Certain Chronic Inflammatory Skin Diseases,” Jour. Cutan. Dis., 1909, p. 379, has been throughout a strong exponent of this view, and his long and large experience (as indicated in this paper) has served to confirm him in this belief.

flammatory character. The general treatment, therefore, is to keep in view the maintenance of a proper condition of the general health of the patient, and if that be defective, be corrected or modified, if possible, by suitable measures and remedies. A clue is sometimes given by the amount or character of the urine. In fact, all etiologic possibilities are to be considered. In the absence of any special indications, and yet where the character and extent of the malady, especially in inflam matory affections, are strongly suggestive of some systemic factor, the family history will often throw light upon the possible underlying dis ease tendency—diathesis, or constitutional weakness.
Hygienic living, proper food, well-ventilated rooms, plenty of sun light, outdoor life, unless contra-indicated by the weather; and, espe cially in those of sedentary habits, exercise in moderation; rest in some diseases and cases; and sometimes, when feasible, temporary change of scene and climate—are all to be considered of therapeutic importance. As already indicated in discussing general etiology, in the large majority of cases commonly met with, digestive disorders, such as dyspepsia, gastric catarrh, constipation, etc, are the factors which most frequently call for correction, and the various known remedies for these conditions accordingly play an important rôle.
The dietary, therefore, is often of importance, and sometimes requires supervising directions. In some affections, it is true,—as, for instance, taking the extreme examples of verruca and xanthoma palpebrarum and the parasitic affection, scabies, etc,—the consideration of the question of food would be an absurdity. On the other hand, however, the cases of extensively distributed eczema, of xanthoma diabeticorum, many instances of pruritus, psoriasis, acne, dermatitis herpetiformis, and others, improper feeding is often an important factor, or at least an aggravating influence, and its proper regulation requires attention. The patient is not, however, to be wholly ignored in this considera tion: his tastes, wants, and idiosyncrasies are to be consulted, for some times articles of food usually readily digested by others may, in individual instances, be not only distasteful, but disturbing and fermentative. As a rule, the well-to-do class consumes too much nitrogenous food, and this is not infrequently a more or less damaging factor in some of the inflammatory diseases. Even with this, however, an extreme position is generally unwarrantable, for there are cases encountered in which gastric weakness is a cause, and in which starches are badly borne, the stomachic condition being overcome or palliated by chiefly a meat diet, the eruption often undergoing perceptible improvement as the digestion is thus improved. In other cases a purely milk diet can be employed for a time with benefit; or, more frequently, conjointly with meat once daily. The use of alcohol is, in the inflammatory affections, particularly eczema, prejudicial and directly damaging, and should be interdicted or at least limited, depending upon the habits and needs of the patient—as, for instance, in the old and feeble. The excessive, and sometimes moderate, use of tea, coffee, and tobacco is likewise to be prohibited. As to par ticular foods, those of difficult digestion, and others concerning which there may be a possibility of unfavorable influence, are best avoided; and
108
GENERAL REMARKS ON TREATMENT
among such may be named pork in all forms, especially sausage and scrapple, lobsters, crabs, clams, oysters (except in cold winter season), and other “shellfish,'’ veal, fish, pastries of all kinds, fresh breads, “hot cakes,” waffles, cheese, dressed salads, acid fruits, seeded and acid berries, pickles, usually condiments, except in moderation, nuts, and sweets; potatoes in excess, cauliflower, cabbage, and onions are likewise, especially in some individuals, often detrimental. The cereal foods may ordinarily be taken in moderation, with milk or cream and salt, if desired, but ordinarily with no sugar.
General tonics, both simple and nutritive, as readily to be inferred from etiologic considerations, are often useful in certain skin diseases in which debility or loss of general tone is an influence, as often in eczema, pompholyx, seborrhea, acne, and other affections. Anemic conditions are met with—iron, manganese, sometimes small doses of arsenic and the hypopbosphites; quinin and strychnin are also indirectly not infrequently of service. The most valuable general nutritive tonic, however, in some cases, is cod-liver oil in small or moder ate dosage. The digestives and ordinary bitter digestive tonics, some times with an acid, sometimes with an alkali, by their influence on diges tion are often of service in promoting general invigoration; frequently such, with a laxative, as required to keep the bowels free, will be all that seems necessary or indicated.
Aperients find more than occasional use in cutaneous disease, and the maintenance of a free action of the bowels, especially in the inflammatory affections, cannot be overestimated, as aiding in getting rid of toxic products, and usually improving digestion as well. Ex cept in anemic individuals, the salines are usually to be preferred; they are given in dosage sufficient to produce free action, but not, except rarely, active purgation. As a frequent or daily saline, magnesium sulphate is probably the best, often usefully given with iron, as in the “mistura ferri acida,” but sodium sulphate, sodium phosphate, and the various natural aperient mineral waters are likewise valuable. Calomel, usually in quickly following small doses, administered at intervals of several days or more, can sometimes be employed with advantage, especially if there is suspected torpidity of the liver. One of the most valuable laxatives, as an occasional one, is the antacid magnesia, particu larly valuable when gastrointestinal toxin development is probable. Among the vegetable laxatives cascara, as the extract or fluid extract, is, in my judgment, the most useful, although the other well-known drugs are often used. For infants and young children castor oil, cascara, and gray powder are the most serviceable. Plain enemata, often used, both in infants and adults, as a rule are not to be commended except as a temporary measure, although in some instances in adults an occasional full flushing out of the lower bowel may prove beneficial.
Gastrointestinal antiseptics are of considerable value in some instances of eruptions seemingly due to autointoxication, as urticaria, erythema multiforme, some cases of eczema, etc Among those that may often be used with advantage are the laxative antacid magnesia, minute doses of calomel administered at half-hour intervals

every several days, charcoal, salol, sodium salicylate, minute doses of carbolic acid, and some others.
Diuretics.—These are often useful, and the free action of the urinary flow thus promoted, together with occasional laxatives, often proves very serviceable in some of the inflammatory and hyperemic affections. They can often be employed with advantage especially in eczema, psoriasis, markedly inflammatory acne, and acne rosacea, dermatitis exfoliativa, dermatitis herpetiformis, and like inflammatory disorders. The saline diuretics are, upon the whole, the best, and in this class potassium acetate and potassium bicarbonate. These are also valuable antilithemic remedies, and it is, as a rule, especially in cases with this etiologic basis, that they are found most useful. In such cases, too, sodium salicylate, ammonium salicylate, salophen, etc., often find an important place. In pruritus and other neurotic affections small doses of belladonna can be conveniently used conjointly, as this also has diuretic action, as well as other influence. Other vegetable diuretics are also sometimes given. In all instances water should be taken freely, as this in itself is a good diuretic. Possibly the influence of oil of turpentine, oil of copaiba, etc, noted occasionally in a few dis eases, may be due, in a measure at least, to diuretic action.
General Alteratives.—All remedies, whether simple tonics, di gestives, etc, which improve nutrition are naturally to be classed as general alteratives, but the drugs referred to here are those which possess this property independently of such influence. The chief alteratives of this class are the mercurials, iodin preparations, and the animal ex tracts. It is not unlikely that the alleged alterative effect of some of these drugs may in fact be attributable to their germicidal influence, as referred to further on. There can be no question of the value of mer cury in both the early and late stages of syphilis, and of the iodids in the late syphilitic manifestations, for the evidence of eruptions quickly melt ing away under their influence is overwhelming. As will also be seen in the course of the text, the iodin preparations are not without effect in some cases of strumous affections. The favorable action of the iodid salts in actinomycosis and blastomycetic dermatitis is also attested; its in fluence in large doses in some cases of psoriasis is undoubted, but whether from alterative action or its effect as an alkaline salt is not definitely known. The potassium iodid is the salt most commonly prescribed, but in my own experience sodium iodid is just as effectual in syphilis, and less apt to be disturbing.1 Arsenic is also a valuable alterative.
The preparation of the mercurial to prescribe is greatly a matter of prejudice or personal custom. The protiodid for active administra tion in the early eruptions of syphilis, and the biniodid in association with potassium or sodium iodid salt in the late syphilodermata, are prob ably in most general use, and are those which I usually prefer. In the later stages, however, corrosive sublimate is likewise a favorite remedy with many. Mouth administration is usually satisfactory, but cases are encountered which do not seem to yield to this plan, and in such, inunctions with blue ointment are generally curative. 1 See Dermatitis medicamentosa.

GENERAL REMARKS ON TREATMENT
The hypodermic method is a favorite plan with some. This remedy is likewise found useful in some cases of lichen planus and a few other affections.
Tar and carbolic acid are also remedies which occasionally appear to possess alterative properties, and are sometimes prescribed for this purpose, especially in psoriasis and eczema. The same may be said of phosphorus, which, in 1/100 to 1/20 grain (0.0007 to 0.0035 gm.) dose thrice daily, in pill or oily solution, is sometimes prescribed for lupus erythematosus, lupus vulgaris, and other diseases. It presumably acts through the nervous system, but there is no uniformity of opinion as to its value; it has practically no place in treatment with the large majority of dermatologists. In one or two instances of erythema indura- tum it seemed to me of value; and in zoster, zinc phosphid, from 1/10 to 1/5 grain (0.007 to 0.014 gm.) four or five times daily, is sometimes of dis tinct service. Antimony, warmly supported by Malcolm Morris for acute and subacute inflammatory diseases in robust individuals, notably in eczema and psoriasis, is prescribed in dosage of from 3 to 10 minims or more of the wine three or four times daily. Although this remedy is also somewhat favorably referred to by Crocker, Duhring, and a few others, it is not in very general use, probably owing to the care required in its continued administration, lest depressing or other untoward action should result. Turpentine has been advised in the same affections by Crocker, to be given conjointly with free diluent drinks. Copaiba, according to my observations, occasionally acts favorably in the same class of cases. It is probable that the last two, in addition to some general alterative action, benefit by their diuretic effect as well and pos sibly also have some special alterative influence directly upon the cuta neous structures. Quinin, which is sometimes apparently useful in ery thema multiforme, erythema nodosum, herpes zoster, eczema, and other diseases, especially if there is an underlying malarial element, might also be included in this class.
Animal extracts have lately been playing an important experi mental rôle in cutaneous therapeutics, as well as in other branches of general medicine, and that some have a general alterative influence, as well, possibly, as a special alterative action, cannot be denied; the action is not, however, a regular one, but, on the contrary, exceptional. Thyroid extract has proved valuable in myxedema, and occasionally has some influence in cases of psoriasis, and has also been employed with alleged benefit in lupus vulgaris and other chronic diseases, but its possible untoward effects have limited its use. The dose of the desic cated extract, as furnished in tablet form, varies from ½ to 10 grains (0.035 to 0.65 gm.) or more three times daily, always beginning with moderate doses, and, if necessary, increasing, but cautiously. A glycerin extract is also made. Suprarenal gland extract has recently been ex tolled for vitiligo.
Special Alteratives—The influence of the various remedies men tioned under Germicides, as well as some of those under General Altera tives and other heads, might also possibly be due to special alterative or direct action upon the skin, but the chief exponent of this class, which

might likewise be termed “special cutaneous stimulants,'’ is arsenic,1 when administered in dosage to get its special effects, and which is entirely distinct from its use in small doses as a general tonic This drug probably acts both directly and through the nervous system, and par ticularly, as shown in the experiments by Ringer, Murrell, Nunn, and others, upon the epithelial layers. Clinical observation, both as to its therapeutic action and toxic effects, is corroborative of these observations.2 It is likewise to be considered a potent nerve stimulant, and therefore also of possible value in some diseases of neurotic origin. It is a remedy which is more especially indicated in the superficial dermatoses. Like most remedies which possess some certain value, it was formerly given almost the standing of a panacea, Hunt being one of its most extreme ad vocates; and following this comes the rebound, and in comparatively recent years there has been a tendency with some dermatologists to belittle its value and set it aside, but this is, in my judgment, just as unwarranted as the other extreme. It is, it is true, still much overrated by the general profession, who often prescribe it indiscriminately, fre quently upon the basis of a “skin disease,” and much harm thus results. Its chief value, upon the whole, is in sluggish and sluggishly inflam matory cases of cutaneous disease, those which originate in the epithelial layers or in which these are prominently involved, as psoriasis, lichen planus, and a limited number of persistent dry eczemas; and also in those diseases of neurotic character, as pemphigus, dermatitis herpetiformis, and some others.
Jaborandi, or its active ingredient, pilocarpin, is sometimes of value in cases in which benefit is to be derived from stimulation of the sweat function, as in the dry, scaly diseases, ichthyosis, psoriasis, etc. Cal cium sulphid, sulphur, elsewhere referred to, and some other remedies have also been accredited with special alterative action in certain dis eases, the sulphur preparations especially in the diseases of the glandular structures.
Germicides.—While probably no remedy administered internally is distinctly germicidal, there are, doubtless, some which, in a few dis eases, in some manner, make the body and its tissues an unfavorable habitat for micro-organisms, or which are antidotal to their products. We know that the value of quinin in malaria is based upon this fact, and it is scarcely to be doubted that mercury and arsenic (salvarsan)
1 Sodium cacodylate and, more recently, atoxyl—arsenical preparations—have been variously extolled as valuable substitutes for the ordinary preparations; their alleged lessened possibility of producing toxic action being lauded. They have some, probably an equal, value, but observations do not support the early published statements of marked superiority. Salvarsan has recently largely supplanted these preparations.
2 In a recent elaborate and exhaustive paper on “The Action of Arsenic on the Skin as Observed in the Recent Epidemic of Arsenic Beer-poisoning,” Brit. Jour. Derm., 1901, p. 121 (with many case and histologic illustrations, review of the subject, and references), Brooke and Leslie Roberts conclude as follows: “In the face of the facts which we have endeavored to place before the reader, we have no hesitation in saying that arsenic, and the other members of the nitrogen group, must be distinguished from all other medicaments by the fact that their action, whether therapeutic, pharmaco- logic, or toxicologic, is entirely dynamic, and consists essentially in altering the ratio to the tissues of one of the most active normal ingredients of the body—namely, oxygen.” See also Dermatitis medicamentosa for toxic effects upon the skin and for other litera ture references.
112 GENERAL REMARKS ON TREATMENT
act the same way in syphilis. It is not improbable that other remedies strikingly useful in other diseases may owe part of their success to this action. Cod-liver oil often seems to have this property, independently of its nutritive influence. Sulphur, owing to its exhalation through the skin, internally, may also possibly have a slight influence in lessening the hold of cutaneous micro-organisms, as in the alleged favorable action of calcium sulphid in boils, seborrhea, acne, etc. It has appeared to me that those whose skin has naturally more or less of a sulphurous exhala tion, as shown by the rapidity with which silver or silver-containing jewelry is tarnished, are less liable to exhibit such parasitic diseases as tinea versicolor, ringworm, etc, and on this supposition its administra tion in such affections may be an advantage conjointly with the proper local treatment.
Tuberculin and other prepared toxins or vaccines are remedies or agents whose anticipated effects were presumably based upon some germicidal or antidotal properties. It is well known that in recent years the hypodermic injections of “tuberculin” for lupus vulgaris and the other forms of cutaneous tuberculosis have been employed, and sometimes with a decided effect upon the disease, which is more fully referred to in connection with these maladies. The uncertain and variable effect, however, of this and other prepared toxins, or vac cines, gradually led to their practical abandonment; but in the past few years, chiefly through the enthusiastic work of Wright and others,1 who have endeavored to place their employment upon a scientifically exact bases, various “vaccines” are again being cautiously and tentatively tried in several dermatoses. Wright found by experimental investiga tion in certain diseases, as, for instance, sycosis, furunculosis, acne, tuberculosis, and a few others, that the phagocytic power of the blood was reduced, and that this was neither due to the serum nor to the leukocytes, but to the diminution of some unknown constituents, which

CONSTITUTIONAL TREATMENT 113
he called “opsonins,” and further, that the hypodermic injection of an appropriate “vaccine’’ would influence the quantity or activity of the “opsonins,” and have an effect upon phagocytosis, and indirectly upon the disease. If the dosage of the vaccine was correct, the “opsonic” power of the blood, and consequently phagocytosis, was increased, and by a series of proper dosages could be brought up to normal and exert a favorable curative action; but on the other hand too large a dosage would still further decrease the “opsonins” and thus lessen the phago- cytic power and probably have an intensifying effect upon the disease. This opsonic action was believed to be due to some alteration in the mi crobes which permits their being ingested by the leukocytes; but the effect is now attributed to an increase and stimulation of the “antibodies.” He devised a method (a modification of Leishman’s method) of measuring the opsonic power of the blood which need not be detailed here, and by doing this from time to time he was enabled by this “opsonic index” to reach an approximately correct dosage, and also to regulate its frequency; and in the various diseases named, as stated by him and a few other observers, the curative influence was striking. As is readily inferred, therefore, if “vaccine” treatment of any disease is determined upon, the first doses should be the smaller, and subsequent doses, as well as fre quency, regulated by a study of the “opsonic index.” 1
Vasomotor Constringents.—Several drugs are credited with this action upon the cutaneous vessels, leading to their contraction and the reduction of hyperemia. They are more especially employed in acne rosacea, and less frequently in purpura, pruritus, and a few other affections. Ergot is sometimes prescribed for this purpose, principally in acne rosacea and purpura, usually in moderate dosage. It has also been used in ordinary acne, where lack of tone in the muscular fibers of the skin is suspected. Inasmuch, however, as there is in these cases often gastric irritability or digestive weakness, which the drug frequently seems to increase, its field of usefulness is somewhat restricted. Ichthyol has been highly extolled, especially by Unna, for promoting vasomotor con traction, and as especially useful in acne rosacea, and also in such affec tions as lupus erythematosus and other hyperemic diseases. It is usually administered in capsules, 3 to 15 minims or more three times daily, but opinion as regards its value as a constitutional remedy is by no means unanimous. My own observations do not give it very high rank. Thiol has also been suggested as possessing the same properties as ichthyol.
Analgesics.—Antipruritics—It may be stated, as a rule, that in the inflammatory dermatoses most drugs known as analgesics are often of aggravating influence in their after-effects; less frequently they are directly damaging. This scarcely holds true, however, in such diseases as herpes zoster, which sometimes, on account of the neuralgic pain, requires the administration of such remedies. In this malady opium or morphin can be used if deemed advisable, but in others, espe-
1 More recently, most observers have dispensed with the opsonic test, owing to its difficulties and tediousness, and to the belief that the effect of one or two trial doses gives sufficient indication as to frequency of administration and quantity.

114 GENERAL REMARKS ON TREATMENT
daily those of itchy character, it is apt in its later influence to increase this symptom. The safest drugs to employ for the pruritus, when neces sary, as it sometimes is, to procure a night’s rest, are the bromids and chloral; belladonna, gelsemium, phenacetin, and antipyrin may also be used for this purpose, and in some cases lupulin in full doses may be tried. Upon the whole, however, they are best avoided if possible; relief from the itching can usually be obtained by certain local applica tions, to be referred to.
Natural Mineral Waters.—The use of the stronger natural aperient waters has already been incidentally referred to; their good effects are due to their laxative action. The milder aperient waters, usually taken at the various springs, have the same influence, but, in addition, the large quantities taken serve to keep the kidneys in free action as well, and thus act in two ways. The value of the alkaline waters taken freely is undoubted, but whether of any more service than the ad ministration of ordinary alkalies with plenty of drinking-water is some what problematic. The iron waters and arsenic waters are also well known, and as substitutes for the ordinary drugs have a value, and the same may be said of the sulphur waters, in which laxative influence and alterative and probably antilithemic action are combined; but these waters are not useful in gastric catarrh or dyspeptic cases. Inasmuch as the underlying factor in many cases is a gastrointestinal catarrhal or digestive disturbance, usually with constipation, the most useful spring waters, on the whole, are those of alkaline and slightly laxative character. These are also beneficial in underlying rheumatic conditions. The moderately active laxative waters of an alkaline character are more especially to be preferred with bons vivants—those who have been storing up the effects of overfeeding and overdrinking.
No one can doubt the favorable influence of the natural spring waters if taken liberally, for the reasons given, but taken at home, their effect is relatively nil compared to the influence gained at the resorts them selves, where, in addition to the free drinking of a mildly therapeutic water, are conjoined usually a rigorous dietary supervision and the un questioned effect of change of scene, climate, release from care, etc. These last are the influential factors at drinking springs; the medicinal ingredients of the water are the least potent in the final effect gained.
Simon1 has made favorable reports of the value of injections of sea- water in skin diseases, but others, among whom C. J. White,2 have not been able to corroborate this alleged favorable action.
Electricity.—The general tonic and alterative action of general faradism, galvanism, or static insulation or shock can sometimes be made use of with advantage in cutaneous diseases associated with lack of nervous tone, especially galvanism and static electricity. Shoemaker, Brocq, and one or two others are the only ones who have given much attention to the advantages of electrization, an adjuvant in the manage ment of some cases which, from my own experience with its use, I can

indorse. In some cases of eczema, urticaria, pruritus, and other mala dies or cases showing neurotic relationship its influence is sometimes con siderable.
LOCAL TREATMENT
As a rule, in cutaneous diseases external applications are necessary both for the favorable or curative action exerted upon the malady itself, as well as for the relief of the accompanying itching or other troublesome subjective symptoms. External treatment is, therefore, of great im portance, and generally much more essential for immediate relief than systemic remedies, although in many affections, as already stated, a judicious blending of the two will give far more satisfactory permanent results in the aggregate than local measures alone. It is true some of those running an acute short course, and some of the chronic disturb ances,—relatively few in number, however,—are not influenced by external treatment, and unless demanded by annoying itching, burning, or pain, local applications are unnecessary.
The measures employed in the external management of skin diseases are varied, and are mentioned with more or less detail, and their special manner of employment described in connection with the diseases in which they are employed, each more particularly in that disease wherein the method or drug finds its most prominent employment. To avoid unnecessary repetition, but brief reference in a general way will, therefore, be made here, and only to those most commonly resorted to. The essen tial underlying principles of external treatment should be mild, soothing, and protective applications for acutely inflamed surfaces; similar prepara tions in the early part of the treatment of subacute inflammatory types, moderately stimulating for those of sluggishly subacute or with slight infiltration, and actively stimulating for thickened, infiltrated, sluggish areas. Various modifications are often required to suit the individual case. Fortunately, most of the remedies thus employed are antiseptic, and this is a very important factor in cutaneous therapeutics.
Water.—Baths.—Water is employed for two purposes—cleanli ness and to remove the products of disease. As a general rule, in acute inflammatory disease, notably in many cases of eczema, it is prejudicial, and its use, therefore, restricted as much as is consistent with the require ments just stated; in some instances of acute irritability its place must be taken by some cleansing oil or grease, such as olive oil, almond oil, cold cream, or vaselin. A thorough soaking with one of these, especially the oils, will usually soften crusts or scales rapidly and facilitate their removal; sometimes the parts must be kept bathed with it by means of compresses, and renewed from time to time. In such instances water can almost be dispensed with or used only at intervals. Rain water or boiled water is less irritating than ordinary water.
In some of the hyperemic and more acute diseases, and in chronic diseases of a somewhat acute or subacute type, such as dermatitis exfoliativa and some cases of eczema, baths made mucilaginous with gelatin (about ½ to 1½ ounces to the gallon), starch (about ½ to 1 ounce to the gallon), bran (about 1 or 2 ounces to the gallon), are usually
116 GENERAL REMARKS ON TREATMENT
soothing in character, and sometimes permissible and palliative in their effect. On the other hand, in some cases and some diseases of a sluggish, chronic, scaly character, such as, for instance, ichthyosis and most cases of psoriasis, the free use of water for washing and cleansing, or in the form of baths, plain or medicated, is not only not damaging, but is often a very important factor in the treatment. The warm to hot bath is frequently sufficient in the less aggravated cases, or it can be made alkaline, as is frequently necessary, by the addition of a varying quantity of an alkaline salt, depending upon the character and tenacity of the scales and the irritability of the skin. Those commonly used for this purpose are sodium bicarbonate (averaging 1½ drams to the gallon), sodium borate, potassium carbonate, or ammonium muriate (averaging a dram to the gallon). The sulphur bath is occasionally used in the chronic sluggish dermatoses, and is best made with potassium sulphid or Vleminckx’s solution (averaging a dram to the gallon). The salt bath (averaging 3 ounces to the gallon), as commended by Piffard, is also useful in some of these cases. Tar baths are, at present, not much used. Corrosive sublimate baths will be referred to in the course of the text. An ordinary tub-bath takes about 30 gallons. The bath should always be taken warm enough to permit of immersion for from three to twenty minutes without chilling.
Steam and hot-air baths are only occasionally advisable in derma- tologic practice, and in the same diseases in which alkaline baths are prescribed. The cold shower or plunge may also be of service in ex ceptional instances, but in cutaneous therapeutics has an extremely lim ited usefulness. The same may be said of the wet-pack. The natural spring-water baths are also sometimes resorted to, and the effects, owing to the methodic manner in which they are carried out, and supplemented by the advantages of change of environment, diet, etc, are sometimes striking.
Soaps are frequently demanded in connection with the use of water for cleansing purposes, but should be even more rigorously excluded in acute eczematous diseases and similar conditions. But the same reasons why water must sometimes be used also hold with soap, but great care should be taken to remove such washings with clean water. There are two classes of soaps, the mild and the strong—the soda soaps, of which Castile soap is a representative, and the potash soaps, of which sapo viridis is the one commonly employed. The soda soap should be as nearly neutral as possible. Its use for toilet purposes has an influence in keeping the skin in healthy condition, but in those of thin epidermis and sensitive skin must be employed in moderation, and exceptionally individuals are met with whose exposed skin, especially the face, does not bear well even its occasional use; in some instances, however, this signifies that the soap contains too much free alkali. As a rule, the washing of the face when using soap, especially on skin at all sensitive, should be done at bedtime; if done during the day, the exposure to wind and weather is irritating. An attempt to overcome this has led to the manufacture of a “superfatty soap,” which is less irritating to some skins, but it is sometimes uncertain in this respect with others. Soda soap,

more freely used than for ordinary toilet purposes, is of advantage in the treatment of acne and some other affections, and it may also be used in some cases in connection with the warm bath in place of the alkaline salt. Sapo viridis may also be so used, but it represents a stronger alkaline bath.
This latter, known also as sapo mollis, or green soap, is a strong soap, and should not be employed in diseases of an acute or, as a rule, subacute type. For removing adherent scales and crusts in sluggish conditions, however, it is sometimes valuable; also in some cases of acne, seborrhea, and psoriasis of the scalp, etc. It may often in these cases be used with greater advantage in the form of the tincture of sapo viridis, corresponding to the spiritus saponatus kalinus of Hebra. The best sapo viridis is that imported from Germany; the extemporaneously made soap having, espe cially in tincture form, proved, in my experience, often unsatisfac tory.
Medicated soaps, made by the addition of various drugs to the soda soap basis, are now prepared by various manufacturers, and while their action is often questionable and their field of usefulness small, occasionally they may be prescribed advantageously—as, for instance, the sulphur-naphthol soap, for body toilet use after an apparent cure of tinea versicolor. Medications have also been made to the super fatted basic soda soap. The tincture of green soap can often be ad vantageously medicated with resorcin and other drugs for use in the shampoo for seborrhea, etc.
Dusting-powders have a somewhat limited field in cutaneous medicine. They are prescribed in the erythemata, especially ery thema intertrigo, in erythematous eczema, hyperidrosis, bromidrosis, and some other affections. Those in more common use are zinc oxid, starch, lycopodium, rice, talcum, magnesium carbonate, boric acid, zinc oleate, zinc stearate, and others, those most valuable being referred to under eczema and other diseases in which they are employed. They are variously used for their protective, antiseptic, astringent, and drying properties. They are not applicable where there is free gummy or puru lent discharge. The first requisite of a good dusting-powder is that it should be absolutely free from grittiness, which can be readily ascer tained by rubbing some between the two finger-ends.1
Lotions are much more agreeable applications than ointments, and are useful in many diseases, in some of which they may be used alone. In others they are found too drying to employ continuously,
1 Kapp (“Ueber Toilette and Schmink-puder,” Derm. Wochenschr., 1912, liv, p. 458) has studied the various vegetable and mineral powders, especially from the point of their mechanical action on the skin, and also made examinations for germ contamination. The material was (67 specimens—powders, powder-boxes, powder- puffs, etc) obtained from private patients of the better class. Only 5 specimens were free from organisms. In 53 were found non-pathogenic organisms; 2 showed mucor mucedo; 1, a hyphomycete; 3, staphylococcus pyogenes aureus; 1, Unna’s morococcus; 1, streptococcus; 1, tubercle bacilli. The vegetable powders have the disadvantage of the swelling of the granules from moisture, and when within the follicular openings possibly provoking enlarged pores; in this respect, rice powder is the least harmful. Mineral powders may produce mechanical irritation by the sharp edges and spiculæ of the grains; the least harmful mineral powders being zinc oxid, precipitated magne sium carbonate, and magnesium silicate.
1l8 GENERAL REMARKS ON TREATMENT
but can be satisfactorily used intermittently or conjointly with oint ments. They are probably most frequently applicable in acne, urti caria, pruritus, erythema intertrigo, some cases of eczema, etc. In some cases the drying effect can be lessened or abolished by the addition of from 1 to 5 or 10 minims (0.065 to 0.33 or 0.65 gm.) of glycerin to the ounce (32 gm.), but this ingredient should rarely exceed this amount in most instances, as it may prove irritating, whereas in minute quantity it is often a valuable addition. From 5 to 10 minims (0.33 to 0.65 gm.) of alcohol to the ounce (32 gm.) may also frequently be added with advantage for the pleasant, cooling sensation it produces—when not contra-indicated, as it would be in exceedingly acute conditions, more especially, however, when the rete or corium is exposed.
According to the effect desired, lotions are of various characters, as indicated by the following qualifying names—soothing lotions, anti septic lotions, astringent lotions, stimulating lotions, antipruritic lotions, etc. They will be found specifically referred to in connection with the various diseases in which they find application.
As an example of an extremely mild, soothing lotion may be men tioned that usually designated calamin liniment, calamin-zinc-oxid liniment, consisting of 1 to 2 drams (4-8 gm.) of zinc oxid and calamin, 4 to 10 minims (0.26-0.65 gm.) of carbolic acid, and 2 ounces (64 gm.) each of lime-water and oil of sweet almonds. These pulverulent ingre dients make it of a slightly astringent and protective character. In some instances olive oil instead of the almond oil seems more accept able. It is to be applied frequently by tapping it on, or the parts can be kept enveloped with cloths or lint wet with it. Closely similar, but dis tinctly drying in its character, is the plain or aqueous well-known cal- amin-and-zinc-oxid lotion, consisting, in the average formula, of about 1 or 2 drams (4-8 gm.) each of calamin and zinc oxid to the 4 ounces (128 gm.) of water, or of 2 ounces (64 gm.) each of lime-water and plain water; to this is sometimes added, in minute quantity, as stated above, carbolic acid and glycerin. This is especially valuable in some cases of erythematous and vesicular eczema of the acute type, in erythema intertrigo, and some other affections. Both these powders seems also to be slightly antiseptic, but this property of the lotion can be further emphasized by the addition of from 5 to 15 grains (0.35-1 gm.) of boric acid to the ounce (32 gm.), and which does not compromise its soothing character. Lotio nigra, with an equal quantity of water or lime-water, is another example of a soothing antiseptic lotion. As a plain antiseptic, soothing lotion, free from sediment, may be mentioned one of boric acid of the strength just indicated, and which can often be used alone, but also more frequently with great advantage conjointly with a soothing salve. It is one of the most valuable mild antiseptic lotions we possess, and in my practice is indispensable. Astringent lotions in the strictest sense are those containing tannin, alum, zinc sulphate, and the like, used most commonly in hyperidrosis. The stimulating lotions are well illus trated by the sulphur washes and tarry lotions, prescribed respectively in acne and chronic eczema. Antipruritic lotions will be referred to under the head of Antipruritics.

Ointments are the most frequently employed preparations in cutaneous therapeutics, and, upon the whole, in many cases, are by far the most valuable; they probably find their greatest usefulness as applications in eczema, to which the reader is referred for many points concerning the various formulas and other matters not here touched upon. The best ointment bases are: (1) Prepared lard, which is the best all-round base, possessing penetrating powers scarcely exceeded by any other fat, but which has the disadvantage of tending, after a time, to rancidity, and should therefore always be fresh; (2) petrolatum, or its equivalent, vaselin or cosmolin, is also valuable, having but little tendency to change, constituting a good protective, but lacking some what in its power of penetration, although Luff's experiments point to the contrary; occasionally, either from imperfect purification or for other cause, it is found to disagree; (3) cold cream (unguentum aquæ rosæ) is soothing and cooling, and is to be considered an admirable base, when properly made, and may often be used when other fatty applications disagree. These three, used sometimes separately, sometimes in mixture of two or all, are those which will be found most satisfactory. To these, other fatty substances, such as spermaceti, wax, suet, and the like are sometimes added for special purposes, and of which simple cerate (cera- tum simplex), simple ointment (unguentum simplex), are some pharma- ceutic examples. The stiffer substances are necessary when a good deal of liquid medication is to be added, such as lead-water, oil of cade, etc.; if an aqueous substance, and in much quantity, enough lanolin with which it can first be rubbed up, together with variable amounts of simple cerate and lard, or petrolatum, can be satisfactorily employed as the base. Lanolin, introduced by Liebreich, and since more or less generally advised, is said to surpass in its power of penetration all other bases, but this is not borne out by experience; and it is an unsatisfactory and even impracticable base when used alone, but in the proportion of from 10 to 20 per cent, to other bases, it is sometimes a valuable addition in seborrhœa and ringworm of the scalp, and some other maladies. Water readily mixes with it, but this ingredient with this fat does not seem to have the cooling influence that it does in cold cream. Adeps lanæ is a closely similar preparation to lanolin. Glycerite of starch is another base occasionally employed, but is not in general use, and sometimes produces irritation. Upon exposed surfaces it is some times an advantage, purely cosmetic, to add a small quantity of calamin, umber, etc., to give the ointment selected a skin color (see under Eczema).
Ointments are of various characters as regards the incorporated medicament—soothing, stimulating, etc. Soothing or mild ointments find their use in irritable and acutely inflamed cutaneous maladies, as in eczema of such type, and not only protect the skin from irritation, moist ure, air, or other injurious influences, but are directly comforting and healing to the diseases surface. The best exponents of this class are the zinc-oxid ointment, cold cream, simple ointment, cucumber ointment, and a few others. Zinc oxid, as well as calamin, bismuth subnitrate, and some other substances, in the proportion of from 5 to 15 per cent, or
120 GENERAL REMARKS ON TREATMENT
more, add slightly astringent and mildly antiseptic properties to such ointments, and are rarely detrimental. The addition of from 2 to 5 grains (0.135-0.33 gm.) of salicylic acid or from 5 to 10 grains (0.33-0.65 gm.) of boric acid, adds still further to the antiseptic character, and, as a rule, is not in this quantity disturbing, even in acute conditions, but all such additions in these cases must be made with caution. Cocoa-butter can also sometimes be added with advantage in the quantity of from 5 to 10 per cent.; it has a stiffening influence on the ointment consistence. Diachylon ointment is much used in Vienna, and if well made and fresh, is in many cases grateful, but it does not seem possible to be sure of a good preparation, and one improperly compounded or old or rancid is sure to irritate. Mild ointments are applied either by anointing or by spreading on patent lint or other suitable material; if lint is used, the ointment should be spread on the woven side, as, being free from fuzzy particles which are apt to stick to the skin, as well as being less likely for the fibers to break apart when the salve is spread on. It may also be applied on paraffined or waxed paper, being thinly spread; this is more especially applicable on parts where there is but little motion.
A good example of an antiseptic, and yet mild salve, in addition to those named, is the boric acid ointment (unguentum acidi borici). Stimulating ointments are constituted of one or more of the several bases named, with the addition of a drug having stimulating properties, such as sulphur, tar, white precipitate, calomel, or other mercurial, resorcin, salicylic acid, chrysarobin, etc., and, according to the proportion present, they vary from one scarcely stronger than a soothing salve to that actually caustic. Stimulating salves are usually to be well rubbed in.
Pastes are a form of ointment suggested by Lassar and elaborated by Unna and others, which are largely made up of pulverulent sub stances, most commonly starch and zinc oxid, with usually a petroleum fat as the fatty constituent. Lassar’s formula—Lassar’s paste— consists of 1 part each of zinc oxid and starch and 2 parts of vaselin, to which is commonly added 1 or 2 per cent, of salicylic acid—salicylic acid or salicylated paste. Duhring commends highly a somewhat softer paste, and more cleanly, consisting of 1 part boric acid, 3 parts each of zinc oxid and starch, and 12 parts vaselin. Others will be found referred to under Eczema. These preparations are often of greater value than ordinary ointments in some cases of eczematous disorders of a subacute or not too acute type, owing to their stiffer consistence and to their greater adhesiveness, and also to their porosity; they make a thin, usually rapidly drying, protective coating.
Attempts have been made from time to time to find cleaner, ready- made and spread ointment applications to take the place of the ordinary salves but so far the preparations known as salve-mulls or salve-muslins, devised by Unna and manufactured in Germany, and now obtainable in most of our large cities, are the only satisfactory substitutes; these often act very satisfactorily, the zinc oxid salve-mull being especially valuable. Their costliness is a disadvantage, and considerably limits their employment. Plaster-mulls, or plaster muslins, also devised by Unna, are adhesive, plaster-like applications, variously medicated

121
with mild to stimulating or caustic ingredients which have a more limited field; a tolerably fair substitute is now found in the “rubber plasters” of our own plaster manufacturers.1
Oils are sometimes used in place of salves, both for the removal of crusts and scales and for the purpose of medication, especially upon the scalp; they may be variously medicated. Olive oil, almond oil, liquid petrolatum, and oil of cade are among those most frequently employed. These and others will be. referred to in connection with the diseases in which they are used. Oily preparations, as well as lotions without sediment, are best applied to the scalp by means of an “eye- dropper,” putting a drop here and there and then spreading or rubbing in with a piece of woolen rag.
Fixed Dressings—But little reference need be made to such in this place, inasmuch as those commonly used are sufficiently fully con sidered under Eczema and Psoriasis. In a way the salve-mulls, plaster- mulls, and rubber plasters already referred to are to be considered in this class, especially the latter two, which are adhesive and can sometimes be kept applied several days without change. Their use is, however, limited, and principally to some sluggish, chronic, thickened, dry types of eczema, patches of lichen planus, keratosis palmaris, and other epider mic thickenings, as clavus, and in some cases of lupus and tubercular syphiloderm.
Tragacanth, bassorin, and acacia mucilaginous applications, as well as gelatin dressings (glycogelatin), have been employed in recent years, and will be referred to specifically under Eczema.
Collodion and liquor gutta-perchæ also furnish rapidly drying coat ings, and may likewise be variously medicated. Collodion is more valu able than the gutta-percha solution, as it dries more quickly, is a thicker, firmer film, and exerts a more positive compressing action, which is of advantage. It has its chief field in psoriasis, in lupus erythematosus, in ringworm, small thickened patches of sclerous eczema and of lichen planus, callositas, and other keratoses. In psoriasis and ringworm, chrysarobin, formerly known as chrysophanic acid, is usually the medic inal ingredient, in from 10 to 15 per cent, proportion, sometimes with from 2 to 5 per cent, salicylic acid; and frequently this last alone, as in occasional cases of ringworm, callosities, clavus, etc. Oil of cade, pyro- gallol, known formerly as pyrogallic acid, and other drugs are also thus used. Collodion paintings, especially of pyrogallol and resorcin, some times act with unexpected energy, so that some caution is at first neces sary. As a rule, unless the added ingredient is an oily one, a mixture of equal parts of plain collodion and flexible collodion is a more satis factory vehicle, the former alone tending to crack too easily, the latter drying somewhat less rapidly and not possessing the same compressing power. In those instances where this last property is especially desired, as usually in lupus erythematosus, the plain collodion is the best. Other details will be found in connection with the various diseases in which this vehicle is employed, especially psoriasis. The gutta-percha solution,

GENERAL REMARKS ON TREATMENT
or traumaticin, is used chiefly as a vehicle for chrysarobin or salicylic acid, in the treatment of psoriasis and some keratoses.
Salve-pencils and paste-pencils, the former composed of wax, oil, sometimes with a gummy or resinous substance added, and the latter usually of a variable mixture or compound of tragacanth, acacia, starch, and other ingredients, haVe been brought forward, with different medica ments incorporated, for application to small spots or areas, but their field of usefulness is so extremely small that special comment is not necessary.
Antipruritics.—Carbolic acid is the most valuable antipruritic, and is often added for this purpose to ointments or lotions—in the former from 3 to 30 grains (0.2 to 2 gm.), and in the latter from 2 to about 10 grains (0.135-0.65 gm.) to the ounce (32 gm.), the proportion depend ent upon the condition of the skin and the obstinacy of the pruritus, markedly inflammatory cases, and especially in children, requiring the smallest quantity. It is most agreeably prescribed in lotion form. Occasionally it is not well borne. Liquor carbonis detergens (formula under Eczema), a solution of coal-tar in an alcoholic solution of soap-bark, is somewhat similar, and an exceedingly valuable remedy, used in lotions chiefly from 1 to 3 drams (4-12 gm.) or more to the half-pint (256 gm.); or in ointments, 5 to 30 minims (0.35-2 gm.) to the ounce (32 gm.). Resorcin, from ½ to 5 or 10 grains (0.035-0.65 gm.) to the ounce, accord ing to the condition or disease, frequently exercises an antipruritic and quieting action. Boric acid in solution, usually saturated, also seems at times to exert, probably indirectly, a mild, quieting, soothing, or anes thetic action, and can often with advantage be made the basis for the other more active remedies just mentioned. Weak alkaline lotions, 2 to 16 grains (0.135-1 gm.) of borax or sodium bicarbonate to the half- pint (256 gm.), are also sometimes of service in certain itching diseases, but are usually not to be employed in eczema. Menthol, hydrocyanic acid, liquor picis alkalinus, other tarry preparations, and other drugs, are sometimes employed for antipruritic effect, and will be referred to else where, especially under Eczema and Pruritus.
Parasiticides are those remedies which are destructive more espe cially to the grosser animal and vegetable parasites. Among the most valuable are sulphur and its compounds; among the latter, especially sulphurous acid, the sulphite and hyposulphite of sodium, the sulphid of calcium, especially as the compound known as Vleminckx’s solution, and potassium sulphid. These, as others, such as naphthol, the mer curials, and carbolic acid, are destructive to both animal and vegetable parasites, and find their employment chiefly in ringworm, favus, tinea versicolor, and scabies. Chrysarobin and iodin are also valuable vege table parasiticides, and both Shoemaker and Crocker speak well of copper oleate in ringworm, and the former commends its action also in other vegetable parasitic diseases. In scabies precipitated or sub limed sulphur and naphthol, of those named, are most commonly em ployed; frequently also styrax and balsam of Peru. The mercurials, especially corrosive sublimate solution, white precipitate, sulphur, stavesacre, and naphthol ointments, are commonly used against pediculi.

In fact, the so-called parasiticides are numerous, as will be found in the text devoted to the parasitic diseases. They are in reality the same as antiseptics and bactericides, these latter usually meaning those which are, as a rule, somewhat weaker, and employed against the lower organisms, such as the pus-cocci, etc In this class are boric acid, carbolic acid, resorcin, weak corrosive sublimate solutions, weak solutions of formal- dehyd, washings with tincture of green soap and water, and many others, the most valuable in dermatologic practice being boric acid and resorcin. The value of ichthyol as an external application, the first knowledge of which we owe to Unna, is, in part at least, due to its bactericidal property, as attested by its favorable action in sycosis, furuncles, acne, etc There are two varieties on the market, sodium ichthyol and ammonium ichthyol, the former usually going under the name of ichthyol. Aristol, acetanilid, iodoform, and others are also occasionally resorted to, but the last named, owing to its offensive odor and its venereal suggestiveness, should find rare application among respectable ambulatory patients.
Caustics are substances or agents which are more or less active destroyers of tissue. Among the strongest more commonly employed in dermatologic practice, and which are destructive alike to normal and morbid tissue, are caustic potash, chromic acid, zinc chlorid, and the galvanocautery and actual cautery, including the Paquelin cautery. They are used in malignant growths; chromic acid and caustic potash are sometimes used on warts. Caustic potash is an active caustic, and sometimes misleading at the time of its application as to the actual amount of destruction taking place; unless, therefore, care is exercised, it may destroy too much. When sufficient action has been effected, vine gar or dilute acetic acid should be applied to the part to neutralize it and prevent further destruction. The pain is considerable at the time, but rapidly subsides. Zinc chlorid, usually applied in paste (see Lupus and Epithelioma), is slow and increasingly painful, but valuable, producing a hard, leathery slough. Another caustic frequently resorted to, and which is in a sense elective, sparing, as a rule, normal tissue unless ap plied for too long a time, is arsenic. It is used in limited growths, such as small epitheliomata, as a paste with usually 1 or 2 parts of acacia; or to more extensive areas, as in lupus, as a 5 to 10 per cent, ointment. It requires from one to several days, according to the strength used; some times a repetition is necessary. It is painful, and produces marked in flammatory edematous swelling, but if used with proper precautions it can scarcely be said to be dangerous. Pyrogallol has the same elective action, but not so constantly. Its method of application, as well as that of the other caustics, will be referred to under Lupus vulgaris and Epi- thelioma. Pyrogallol in collodion sometimes acts unusually sharply, and when so prescribed, must be done, at first at least, with caution. Nitric acid and the acid nitrate of mercury, are comparatively super ficial caustics, and are sometimes employed in warts, nævi, and other cases in which slight or surface destruction is sought. Trichloracetic acid (the deliquesced crystals, or saturated solution) is also an extremely useful, somewhat superficial discutient and caustic which has recently been much extolled (C. N. Davis, D. W. Montgomery and Culver,
124
GENERAL REMARKS ON TREATMENT
Heidingsfeld,1 and others) for seborrhœic and senile keratoses, warts, simple moles, xanthoma, and similar lesions. Lactic acid, if used freely and continuously, also has caustic action, but if applied scantily its effect is superficial, or more that of a discutient. Among other discutients or keratolytics is salicylic acid, used as a 10 to 25 per cent, rubber plaster or plaster-mull, or as a 10 to 25 per cent, solution in collodion, or a 10 to 25 per cent, ointment (applied as a plaster); in epidermic thickenings it is often of great service. Other caustics are occasionally used, and will be found referred to in the course of the text.
Liquid Air and Carbon-dioxid Snow.—While treatment of certain cutaneous diseases by intense refrigeration, mildly or actively destructive according to degree and application, has been from time to time recorded and liquid air had several times been publicly and pre viously lauded by A. C. White and others, it remained for Dade’s brilliant demonstration of the use of liquid air2 at the meeting of the American Dermatological Association in New York, 1905, to give this method an established and accepted standing; especially valuable in pigmented and vascular nævi, lupus erythematosus, keratoses, superficial epithelioma, and the like.
Liquid air as an efficient, and probably the best, destructive refrig erant or freezing cauterant, has since had the endorsement of Jackson, Saalfeld, Beckett, Trimble, Zeisler, Whitehouse, and others, but the almost insuperable difficulty in obtaining and preserving it has almost led to its entire abandonment, the more readily owing to Pusey’s valu able discovery (1905) of a practical substitute for it in the easily and always procurable carbon-dioxid snow. Its degree of cold is not so low as that of liquid air, but it is low enough, and the action is about the same. Since then its value has been repeatedly attested by Pusey, Heidingsfeld, Zeisler, Bowen and Towle, Sutton, Jackson and Hub- bard, Hutchins, Gottheil and Schalek, and others.3 My own expe rience has been equally favorable. Liquid air is applied with a cotton

swab, made by wrapping a piece of cotton around the terminal part of a flat piece of wood, which can be made of suitable size and shape for the case in hand. It is applied with moderately firm pressure, and for from ten to thirty seconds or more in deep-seated formations. The degree of action depends upon the amount of pressure and the duration of the application. The after-effect is almost the same as that following the application of carbon-dioxid snow, as described below.
Carbon-dioxid snow is generally obtained from the large steel cylinder of liquid carbon dioxid, supplied by soda-water fountain supply com panies; it can be kept in the office or cellar and drawn from as the snow is needed. It is a clumsy apparatus and, for the office, unsightly. A much more elegant and convenient source is the small cylinder (12 inches long, 1¼ inches in diameter) of liquid carbon dioxid sold by certain auto mobile supply-houses for the easy inflation of the tire; one cylinder furnishes ample snow for a single treatment. With several of these cylinders and the necessary valve-cock at hand one is sufficiently well supplied. When necessary an angioma in an infant can be treated at its home, as a cylinder and the valve-cock can be easily slipped into one’s pocket. The method of procuring the snow is simple. A somewhat thick chamois skin (or a thin one doubled) is tied over the gas-nozzle in such a manner as to leave a small pocket opposite the gas outlet; the out let end of the cylinder, if the large one is used, should be dipped down about 6 inches lower than the other end; if the small cylinder, the outlet end is held about perpendicularly down. The gas is then turned on (by puncture of the seal in the small cylinder) and the snow collects in the chamois pocket, which, when ready, is detached from the nozzle. It is either then manipulated through the chamois to form a ball, which may be cut to the required shape and size, or it may be packed or rammed into a hard-rubber mold, such as an ear or nose speculum or a small section of a larger tube. It is then ready for the application.1 The snow pencil or mass is to be handled by the operator with a small piece of chamois so as to avoid personal damage to the skin; it is then applied to the diseased patch with a moderate pressure, and held there from ten to sixty seconds; even longer in deep-seated disease. The duration de pends upon the object desired; as a stimulant and discutient, as, for ex ample, in thickened patches of lichen planus or eczema, a few seconds may be sufficient; in small superficial angiomata, in thin pigmented nævi, superficial lupus erythematosus, etc., ten to thirty seconds; in lupus, epitheliomata, etc., from thirty to sixty seconds or longer. In with drawing the snow pencil or mass the area is seen depressed and frozen white and hard, with a slight, narrow surrounding zone of erythema. It thaws out in a few minutes, becomes red, and possibly slightly swollen; later, trifling vesiculation or a distinct bleb or blister forms. This can be punctured. Later, slight exfoliation or thin crusting usually takes place, and after a time drops off, leaving a scarcely noticeable scar; in cases where the action has been superficial, scarcely more than a whitish mark, sometimes no permanent trace. When the action has been long

continued and with considerable pressure there may follow thin sloughing, usually of a dry character. There is not much (rarely objectionable) pain, as a rule, in the application, but while thawing and for a short time subsequently there may be in some instances considerable discomfort, rarely troublesome. In most instances no after-treatment or dressing is necessary, unless on covered parts where the clothing may rub. Later, the superficial abrasion or ulcer may need a simple protective application. If later observation shows that the action has not been sufficient, the snow application is to be repeated. A large area of disease, as, for instance, in lupus erythematosus or in nævi, should not be treated at the one time, but in sections, and in such instances it is advisable to apply the snow in square-block form, so that the surface may be treated evenly.
Mechanical or Operative Measures.—Excision is practised in epithelioma, lupus, and other malignant formations. The cases of lupus and epithelioma, the two principal affections sometimes thus treated by dermatologists, in which permanent success is most promising, are those in which the disease exists as a small, sharply defined, circum scribed patch, the knife going well beyond the apparent limiting border. In more extensive cases of lupus this method has also been recently employed, following it up with skin-grafting by the Reverdin or Thiersch plan; with proper technic and under antiseptic precautions, good results have been secured by those skilled in this method.
Curetting, with the ordinary cutaneous curets, is a much more common recourse in dermatologic practice, and is extremely valuable in certain diseases, more especially in lupus vulgaris and epithelioma, but it should rarely be relied upon alone, a supplementary light cau terization, especially with pyrogallol salve or caustic potash solution, as described under these diseases, always being practised. Under this conjoint plan recurrences are much less likely to present than if curetting alone is depended upon. This instrument, with sharp or blunted edges, is also employed for other minor purposes, and such will be re ferred to in the discussion of the individual diseases in which it finds use.
The galvanocautery and Paquelin cautery, and Unna’s small modifi cation of the latter, the microcautery (Microbrenner), already men tioned under caustics, are often used to destroy tissue, in lupus espe cially. Besnier was a strong advocate for the galvanocautery in this disease, used with sharp and pointed instruments.
Linear and punctate scarifications with the single blade or sharp point, or with the variously devised multiple scarifiers, are found useful chiefly in lupus vulgaris. They are sometimes employed also in lupus erythematosus, and occasionally in small thickened sclerous eczematous areas. Punctate scarification is also resorted to in acne rosacea. The puncturing and incising knife or acne lance can often be employed with advantage in sluggish and suppurating acne lesions.

sionally resorted to for minor operations, as in the removal of gun powder grains, small-sized tattoo-marks, moles, epitheliomata, and other growths. Probably its most common use is in the removal of diseased tissue for pathologic investigation.
Comedo extractors are variously shaped small instruments with a central hole, varying from that of the ordinary watch-key-like instru ment to that somewhat similar to a long double curet, but with the shank curved toward the ends.
Electrolysis, sometimes termed the electric or electrolytic needle operation, which we owe principally to Hardaway, is an extremely valuable procedure in certain diseases or conditions, as in the smaller nævi, telangiectasis, acne rosacea, warts, for the removal of superfluous hair, etc, and its method of employment will be found described in connection with these maladies. Electrolytic destructive action can also be effected by means of small metallic discs, and is sometimes em ployed for this purpose in lupus vulgaris (q. v.), as originally recom mended by Gärtner, Lustgarten, and Jackson.
Electricity can also be used in other ways, the faradic current being valuable in some cases of acne, in alopecia, alopecia areata, and a few other diseases; in the first, applying it by means of an ordinary electrode or roller electrode, and in alopecia by a special metallic comb or brush, and in alopecia areata by means of a tinsel brush. The galvanic current is also a decided cutaneous stimulant, and is useful in sluggish conditions, in alopecia areata used cautiously, in acne rosacea, acne vulgaris, in herpes zoster, and in some other affections. It is not improbable that there may be much more value in the treatment of superficially circum scribed dermatoses by drugs introduced by means of electric cataphoresis than the past few experiments in this direction would seem to indicate. The static current is likewise of adjuvant service, especially in diseases of a neurotic character, the roller applied over the clothing sometimes starting the absorption of infiltration; and the spark applied with the pointed electrode, carefully used, a decided stimulant to the patches of alopecia areata.
Radiotherapy1 (Röntgen-ray Treatment.—x-Ray Treatment).— Ever since the experimental therapeutic use of this agent was stimulated by the recognition of its occasional accidental action on the cutaneous structures, observed by various skiagraphers, the literature of the day has furnished varying statements of its value in many of the dermatoses. Led mainly by Freund and Schiff in Vienna, Pusey and Williams in this country, Walsh, Morris, and Sequeira in England, and Oudin, Barthé- lemy, and Darier in France, its employment has been gradually adopted by all, or almost all, those engaged in dermatologic practice. For the past several years it has outranked everything else in its wide applica tion, and the cutaneous disease was rare indeed that has escaped its trial. Continued observation and experience, including my own, though showing that some of the claims were extravagant, nevertheless

128 GENERAL REMARKS ON TREATMENT
very properly accord it a most important position in the treatment of certain diseases of the skin; while it should not be allowed to supplant other means and methods, it is to be recognized as a potent and helpful addition to our resources, especially in epithelioma, lupus vulgaris, and other cutaneous tuberculoses, in lupus erythematosus, sycosis, extreme and obstinate types of acne, in limited rebellious cases of eczema, ring worm of the scalp, and some other diseases to be referred to in the course of the text. Its possibilities for evil, both for the patient and operator, should rightly limit its use within reasonable bounds and under sufficient precautions. Its reckless and indiscriminate application to any derma- tosis, otherwise easily treated and handled, is to be deplored. It is true that the dangers, with improved technic, and the exercise of care, have been almost reduced to insignificance. There are, however, in dividual idiosyncrasies to be considered. Caution, therefore, should be the invariable rule in the use of this powerful agent, and the first several exposures should be tentative, not closer than 10 inches to the tube, and not more than 3 to 5 minutes’ duration. A certain amount of bold hazard, when one is experienced, is occasionally permissible in such cases as the more malignant epitheliomata and extreme cases of cutaneous tuberculosis, for frequently improvement is not brought about till the first, and sometimes the second, degree of x-ray dermatitis is provoked; but in such diseases as acne, sycosis, eczema, and the like no such risk would be warranted, and action beyond the production of the mildest erythema should be carefully guarded against. While the general hints given here and in connection with the diseases in which it is used will probably suffice for the intelligent, cautious worker, it would be a great advantage for those desiring to employ this treatment largely and thoroughly, if opportunity were first sought to gain at least a moderate practical knowledge with the apparatus and technic from one already familiar with the method.
While it would be exceptional to use more than one tube at the one-treatment exposure, Lawrence,1 in the treatment of granuloma fungoides, generalized eczema, and psoriasis, has employed with benefit as many as six tubes at a time.
The x-ray tube can be excited by either a coil or a static machine, and either will prove satisfactory in cutaneous cases. As to the size of the coil or static machine, the larger (within reasonable limit), prob ably the better, but the coil capable of a good 6-inch spark, or a static machine capable of an 8-inch spark, will be capable of doing good work; the small apparatus requires a somewhat longer exposure, and the rays from a static machine are weaker than those from a coil, but such can be readily compensated for by longer exposure or shorter distance, or both. A coil capable of a 12-inch spark is that in most common use, and this, as well as the larger and heavier static machines, are to be preferred, especially if they are also to be used, with the additional requisite apparatus, for the production of high-frequency currents. The static machine can be operated by hand, water, or electric power; the coil with currents from storage batteries or the street current. The 1Lawrence, “ X-ray Baths,” Jour. Cutan. Dis., 1908, p. 247.

coil has, as is well known, the greater advantage of reliability. Of the various forms of interrupters—mechanical or vibratory, mercury dip, or mercury jet or turbine, and electrolytic—the so-called mechanical interrupter is, upon the whole, the simplest and least troublesome, although they are all efficient, and each has advocates. It is not pos sible to give a fast rule as to the necessary amperage of current for the coil in the treatment, as this varies, depending upon voltage, and size and construction of the coil. Now that such instruments of precision as special ammeters to measure amperage and voltage of the energizing current, and the number of milliamperes actually going through the tube, supplemented by the Wehnelt or Benoist’s penetrometer, Sabouraud- Noiré pastilles, etc, are on the market, greater accuracy and standardiza tion of current may soon be realized; such are very essential if the so- called “single dose” method is practised;1 but one learns a great deal from experience and observation, and safe and successful treatment of most cutaneous diseases is possible in cautious hands without these various additional appliances.
The x-ray tube should be, preferably, the kind that admits of regu lation of the vacuum, as the vacuum of a tube is an important factor in the treatment of cutaneous diseases. As is well known, the rays from a tube of low vacuum exert their action chiefly superficially, and those from one of high vacuum, mainly in the deeper parts. As a rule, in skin dis eases, with some exceptions, a deep action is not required; it should not be more than equal to a 2-inch spark-gap—in other words, a so-called low vacuum or “soft” tube. This has seemed to me the most efficient. Some, however, favor a higher or “medium” or “medium soft” vacuum, and others, again, a higher vacuum, or “hard” tube. If the dermatosis is exceedingly superficially seated, the vacuum can be set low—¼ to ½inch spark-gap—and then allowed to rise. Should the desire be, in some in stances or at times, to have the extreme outer surface of the skin rela tively spared, as obtains in some stages of the treatment of epithelioma and lupus, where surface action is to be avoided or has already been sufficient or troublesome, then a thin sheet of aluminum can be inter posed (Thompson) between the tube and the part treated, thus shutting off or limiting the short or superficially acting rays; instead of the alu minum sheet old tubes that have become considerably darkened and coated with metal can be used.
Great care should be exercised that the wires connecting the tube with the coil or static machine are firmly attached and so placed that there is no possibility of their getting loose or in any other way coming in contact or even in close proximity to the patient, in order that un pleasant shock and unnecessary alarm may be prevented.
An important desideratum in x-ray treatment is the protection of the other parts not being treated. Various plans are in vogue, and are well known. The most common is the covering over of the surrounding and nearby parts with thin sheet-lead or several layers of tinfoil, an opening being made sufficiently large for the diseased area. If the dis-

GENERAL REMARKS ON TREATMENT
ease is on the face, a mask can be made (pasteboard or gauze) and covered with four or five layers of tinfoil, except at the part immediately over the disease, which can be cut out. These devices, however, consume time. In my own work, which is largely for disease seated upon the face or some parts of it, I usually employ the Friedländer shield over the tube; the size of the opening used can be readily regulated. With this or similar shield1 one could do away with the necessity of attaching any protect ing foil to the patient; but it is probably better to place a narrow band of foil around about the diseased area, to protect the surrounding skin from stray rays; this can be fastened with adhesive plaster. Particular attention should be given that the scalp, hair, eyebrows, and eyelashes are protected, for exceptionally a single exposure, especially if at all pro longed, will be followed by complete hair-loss of the part exposed; a regrowth, however, finally takes place. In long exposure the lips should also be protected.
In ordinary therapeutic work the protection, by the above measure, thus given the operator will usually be sufficient to prevent any damaging action. In addition to this an arrangement can readily be rigged so that the current is stopped before the operator approaches the tube. An additional screen can also be placed between the tube and the part of the room where the physician or attendant is seated while the exposure is going on.
Further data as to the action of the rays, both therapeutically and pathologically, as well as the distance of the tube and duration of ex posure, will be found under x-ray Dermatitis and in connection with the diseases in which the method is employed.
In place of the x-ray, radium and other radio-active substances have been variously extolled. Radium has apparently about similar radio- active properties, and probably some properties peculiar to itself. While not so generally applied, radium, in the hands of those skilled in its use (Wickham, Abbey, and others2), produces brilliant results in some con ditions. For use in cavities, such as the mouth, nose, etc, and for easy application to small cutaneous lesions, it has some advantages, more espe cially of convenience. It can be used either in a properly arranged applicator, or, on surface lesions, the glass receptacle or aluminum capsule containing the radium can be fastened with adhesive plaster. The dura tion of the first application should not be, if the preparation is a strong one, more than ten to twenty minutes; after several days it is again re peated, and later, if necessary, and if there are no reactive symptoms, the time of exposure can be gradually lengthened. Duration and fre quency depend upon the activity of the preparation—it should have the highest possible radio-activity; with the weaker preparations the les sened power must be made up by increased quantity and much longer or more frequent application. The weaker, being comparatively inex pensive and safer, can be entrusted to the patients with instructions for exposure at short intervals.

of the application of concentrated light deprived of its heat rays to the treatment of cutaneous disorders. His experimental studies with the concentrated light, demonstrating its destructive action upon bacterial life, led him to apply it to the treatment of lupus vulgaris. Since then he and others have broadened its therapeutic field, and it is now, in some of its forms of application, also used in lupus erythematosus, epithe- lioma, alopecia areata, and some other diseases. While Finsen at first resorted to sunlight, applying it through a properly shaped water-con taining lens, owing to the uncertainty of this source, he and his asso ciates Forchhammer, Bang, and others, subsequently discarded this for the carbon arc-light of high power, this being richer in the acting rays, and always available. The main forms of apparatus are: First of all, the Finsen (so-called large Finsen), and the smaller, similar (Finsen-Reyn) lamps; in these the principle of several condensing lenses, arranged for concentration in a telescope- like tube, is the essential part. This, it is maintained, and doubtless rightly, is necessary for the deep penetration of the rays, and in order to get suffi ciently deep curative action. It naturally necessitates some distance between the actual light and the part being treated, and requires more prolonged ex posure to obtain reaction; the light, therefore, is focused upon the required point. One of the sections between the lenses is filled with distilled water, and around this section there is a thin hollow jacket, through which ordinary water is kept circulating; the heat rays are thus filtered and overheating of the apparatus prevented.
In addition, on the part treated there is firmly pressed a hollow com pressing lens, consisting of two quartz lenses set in a metal band, through which water is also kept circulating; besides still further straining out the heat rays, this compression lens also serves to press out the blood from the tissues, the blood being a hindrance to the deep penetration of the rays. The pressure is maintained by fastening this hollow lens with straps or elastic bands, aided by the attendant. The large Finsen lamp requires with medium commercial voltage a current of 80 amperes; the Finsen-Reyn lamp 20 amperes. Lortet and Genoud, and, later, others, in order to lessen the time of application, as well as to reduce the cost of the apparatus and the amount of current required, discarded the principle of the telescopically arranged condens ing lenses, and constructed an apparatus so as to bring the light close to

GENERAL REMARKS ON TREATMENT
the part treated. This consists of a basin- or bowl-shaped, thin, hollow metallic shield, at the projecting center of which is set a lens, on each side of the shield; the arc light, of carbon points, is brought up close to the inner lens, and against the outer lens the patient presses the part to be treated; the apparatus is kept cooled and the heat rays strained out by keeping water continually circulating through the thin cavity of the shield and lenses. While at first this form of apparatus, known as the French, or Lortet and Genoud, lamp, and as the London Hospital lamp, was lauded as an improvement, further experience has shown it to be much less penetrating, and much less effective in the treatment of lupus. It usually brings about a much more rapid surface-action, but

fails in depth, even when the time of exposure is continued as long as with the Finsen lamps.
It has, however, a field of usefulness in superficial dermatoses, such as superficial lupus vulgaris, alopecia areata, and some others. It requires from 5 to 15 amperes. Bang and others, in efforts to save time in application, constructed a somewhat similarly arranged pressure lamp, having, instead of carbon, hollow-iron electrodes at the arc, which were kept cooled by water running into their cavities. The arc of iron elec trodes is rich in the erythema-producing short rays, and a decided surface reaction can be brought about in a few minutes, but it is still less pene trating than the Lortet and Genoud lamp. It is, however, useful where

a quick superficial action is desired. Moreover, it requires but a few amperes of current. Somewhat similar, but still less active, lamps are those devised by Görl, Leduc, Piffard, and others, in which the light comes from the electric spark between several, or more closely contiguous, metal electrodes; this light is rich in the ultraviolet rays, but its action is exceedingly superficial. Another lamp which Kromayer1 has brought forward as a substitute for the Finsen lamp is that known as the “quartz lamp.” This is a mercury-vacuum lamp, made of melted quartz glass, imbedded in a running water-bath, whose casing, the size of a fist, permits of the exit of the light through a quartz window, which, like Finsen’s compression lens, may be used as a compressorium. There seems to be no question that in lupus vulgaris the most efficient lamps are those known as the large Finsen, and the later smaller one known as the Finsen-Reyn lamp,2 and probably next in value the Kromayer quartz

mercuryvacuum lamp. The Finsen method will be further considered in the section on Treatment of Tuberculosis of the Skin.
In addition to these several lamps intended for the close or con centrated treatment of a limited area, there are others now employed with carbon, carbon-iron, and iron electrodes by which the actinic light is projected by means of a parabolic reflector upon large surfaces;

the heat effects in some of these latter are also of therapeutic value in some cases. These larger reflecting lamps are found useful in those dis eases usually benefited by sun exposure, as psoriasis, some cases of eczema, etc.
The high-frequency current (known both as high-frequency and high-tension currents) probably had its first introduction in medi cine by W. J. Morton, of New York, but the experiments by Tesla, with modern apparatus, and the enthusiasm of D’Arsonval led to its present position in medical therapeutics; it was Oudin, however, who gave it this impetus in the treatment of diseases of the skin, and whose enthusiasm stamped it with almost alluring powers. Many of the claims made for it have failed of corroboration by other writers, but that it has value in some dermatoses, no one who has conscientiously tried it can deny. It is still, however, in the experimental stage, and needs much more ex perimentation before its proper status can be known. The subject has excited sufficient interest to lead to the publication of some mono graphs and to giving it an important place in works on allied subjects.1 Variously shaped electrodes have been designed for its application, but those of greatest value and most generally useful in dermatology are the hammer-shaped vacuum electrode and the carbon, and glass-point, electrodes; and where a more prompt and decided limited circumscribed action is required, a pointed metallic electrode.2
Sundry other measures and instruments sometimes have a use in dermatologic therapeutics, such as poultices for removing crusts; roller bandages for supporting dressings and otherwise aiding in the treatment, as in eczema of the legs associated with varicose veins; rubber or elastic bandages and elastic stockings for similar purpose, but these must be used with caution, owing to possible irritation. Coun- terirritation over the vasomotor centers controlling the affected region— a local measure with, however, a constitutional influence—has been highly commended by Crocker in obstinately recurring eczema and similar inflammatory diseases; it may be effected by sinapisms, blisters, or with the galvanic electrode, or with the point or roller electrode of the static current. Massage or rubbing with oils or ointments is some- times of service in starting up the absorption of inflammatory exudates or induration, and is also valuable in elephantiasis, scleroderma, in alopecia, and some other affections. It has long been known that “stirring up the skin”—i. e., increasing and promoting temporarily active hyperemia—is of benefit in certain cases, and especially in slug gish and chronic areas, and we know now that it does so by accentuating and imitating nature’s method. Some of the measures already men tioned doubtless owe part of their value to this action. Bier’s hyperemic treatment—the production of active and passive hyperemia by means

of hot air, cupping, and bandaging—is another method lately utilized for this same purpose.1
In addition to the various instruments already indicated may be mentioned the dental burr and hook used in the destruction of iso lated tubercles in lupus vulgaris; the depilating forceps, with easy spring, for extracting hairs; a hypodermic syringe, and a slightly larger but similar syringe for washing out acne-abscess cavities; an atomizer for spraying and cleansing purposes; and a small massage cup for local massage of the face, and for favoring bleeding and discharge in the open ing of acne lesions, etc In some cases a glass pleximeter to observe the lesional appearance under pressure, a magnifying glass for more accurate inspection in occasional instances, small grappling forceps, and some other instruments usually contained in an ordinary pocket case, to gether with other special instruments and apparatus mentioned for particular purposes in the course of the text will be found of service in dermatologic practice.
