ERYSIPELAS.

BY JAMES NEVINS HYDE, M.D.


DEFINITION.—Erysipelas is an acute disorder, characterized by the systemic symptoms common to the febrile state, and by an involvement of the integument and deeper parts, the affected surface being tumid, hot, reddened, painful, and often the seat of well-defined bullæ, the process terminating either in complete resolution after cutaneous desquamation or in a fatal result commonly due to complications of the malady.

SYNONYMS.—Eng. St. Anthony's Fire; Fr. Érysipèle; Germ. Rothlauf; Ital. Risipolo.

CLASSIFICATION.—Erysipelas is properly recognized as one of the acute infectious diseases. Though by its symptoms and career it would seem to be properly assigned to the category of the exanthemata, it is yet by most authors set apart from the latter—first, because its career is less specifically defined; second, because its contagiousness is less demonstrable in every case; third, because one attack is not known to confer upon its victims immunity against a second; fourth, because the occasional prevalence of the disease in apparently epidemic form is evidently due to extrinsic causes, and does not depend exclusively upon its sudden appearance among the unprotected; fifth, because no definite period of incubation precedes its earliest manifestations; and, sixth, because at times it appears in local manifestations apparently unaccompanied by systemic phenomena.

HISTORY.—The earliest writers on medicine bear witness to the fact that the disease was recognized at the date when men first made record of human ailments. It has occurred in all parts of the world and at all seasons of the year, sparing neither age nor sex in its development. Zuelzer1 refers to epidemic occurrences of the disorder, described by Rayer, as visiting the Paris hospitals in 1828; by Schönlein, as existing in Zürich in 1836; by Gintrac, as spreading in Bordeaux in 1844-45; and by Trousseau, as prevailing in the Maternité in Paris in 1858.

ETIOLOGY.—Authors have in general assigned different causes to the forms of erysipelas hitherto regarded as either idiopathic (or medical) or traumatic (or surgical). The modern view, however, is that which regards all cases as alike produced by the absorption of the toxic agent capable of exciting this peculiar inflammation of the skin. The peculiarly well-characterized symptoms of the disease—for example, when it affects the head and face—were long regarded as etiologically distinct from the affection which complicates surgical injuries and wounds. But a closer study of many of the cases first named has again and again disclosed the fact that they originated in such traumatism, for example, as the piercing of the lobule of the ear for the insertion of an ear-ring, a carious tooth, an alveolar abscess, or a pathological product in the antrum of Highmore.

The disease is equally common—apart from the puerperal state—in both sexes and at all ages, and occurs under favorable circumstances in all seasons of the year. It is unquestionably at times spread by direct contagion, either from the living or dead body affected with the disease. Such contagion may occur mediately or immediately. It is, however, not readily shown to be producible by the media of clothing and other articles which have been in contact with a diseased surface. The contents of the bullous lesions which appear upon the erysipelatous surface are inoculable; and the disease has in this way been transferred not only to men, but also, by Orth and others, to the lower animals, and even from one of the latter to another of the same species.

Certain it is, however, that the disease does occur, characterized by symptoms indistinguishable from those to be recognized in the contagious type of the malady, where the most careful investigation wholly fails to reveal the cause, and where the disorder rapidly spreads if the conditions for its extension are favorable. Under these circumstances it is wisest at present to admit that the exact etiology of erysipelas is unknown. Its relative frequency in the puerperal state is unquestionably to be explained by the favorable local conditions which at such times exist in the female for the development of all septic disorders.

As regards the circumstances which might be supposed to specially favor its development, these the capriciousness of the disease, which is its striking characteristic, often quite disregards. Thus, on the one hand, it may and often does prevail, year after year, in certain hospitals, and even in certain wards of a single hospital, especially where these are crowded with patients. But it may also repeatedly spare masses of men affected with disease of a different type when the latter are gathered together in prisons or camps, and indeed even may appear among such individuals and fail to spread to others who are in close proximity to them.

With respect to the propagation of erysipelas from infected to sound individuals, a contrast is exhibited when the transmission of variola, for example, is compared with it. Thus, it is well known that the mildest cases of varioloid may be sources of malignant forms of variola to the unprotected, while those who are partially protected and exposed to the virus of confluent forms of the disease may exhibit the mildest symptoms of varioloid. In erysipelas, however, it is tolerably certain that there are different degrees of virulence to be recognized in different cases, and that the disease at times is transmitted in its different types. Thus, traumatic erysipelas is much more closely related to childbed fever than the varieties of the disease appearing upon the head and face, which cannot be attributed to traumatism, surgical accidents, dental abscesses, or local injuries of the antrum of Highmore. Parturient women frequently escape infection when the erysipelatous disorder is of the so-called medical type. Per contra, it is to be noted that women who are prone to the relapsing and so-called chronic forms of erysipelas are particularly apt to suffer from that involvement of the genital organs, peritoneum, spleen, and febrile movement whose sudden occurrence after confinement is so portentous.

SYMPTOMATOLOGY.—The disease is usually announced by the occurrence of a chill, which may precede by a day or but a few hours the appearance of the cutaneous disorder. The rigor may be severe or mild in grade, so that it may even be forgotten by the patient till his attention reverts to it in connection with the resulting symptoms. There may be simultaneously some gastric distress, rarely of severe character. These symptoms are commonly followed by a febrile reaction. In other cases the first recognized symptoms of the malady occur in the skin, the patient scarcely recalling the fact of a slight preceding malaise.

The cutaneous lesions appear in the form of a circumscribed oedema and redness of the surface, often preceded and usually accompanied by a sensation of tension, heat, and burning pain. This macule, plaque, or patch of diseased integument is in its typical features characteristic. It is distinctly or irregularly circumscribed; its oedematous condition elevates its level decidedly above that of the adjacent integument, so that there is a somewhat sudden descent from the former to the latter for a space of from one to two or more lines. The redness is also of a bright crimson hue, and the reddened surface has a sheen or glossy appearance uniformly displayed over its area. It disappears under the pressure of the finger, leaving a yellowish-white color in the region of impact, the erysipelatous blush rapidly returning when the circulation at the surface is restored. This smooth and shining condition of the reddened patch is so characteristic of erysipelas that it arrests the attention of the diagnostician as soon as he observes it. According to Zuelzer, it is caused simply by the tension of the epidermis. When first observed it may occur in the form of circular, small or large coin-sized patches, or in streaks, striæ, and radiations, or as very irregularly disposed, rosy, and shining marblings or mottlings of an oedematous surface.

The skin thus affected is hot to the touch, tender, firm, and smooth. It is occasionally the seat of pruritic sensations, more commonly of a peculiar sensation of heat and burning.

In the course of two or three days the involved area spreads uniformly or irregularly and centrifugally from the point first involved, after which time, in mild cases, the disease persists without apparent change for a few days more, prior to its decadence by resolution. This final stage of the malady is characterized by a progressively diminishing fever, moderate desquamation, gradual disappearance of the oedema, and a color-change to the darker shades of bluish-red or to a light brown. In this form of the disease the erysipelatous patch, after being fully developed, does not tend to spread from the affected to the unaffected surfaces; and, as a consequence, the affection may complete its entire career in less than a fortnight.

In other cases, however, a remarkable tendency is developed to the progressive spreading of the inflammation from one point or surface of the body to another, the parts first affected paling as the disease passes on to involve those in the vicinity, or being yet deeply involved while the process of peripheral extension is in progress. In yet other cases the red blush sweeps away from its first position in tongue-like projections over a tumid and painful skin, while the region first invaded becomes paler, though still preserving its oedematous features. In still another class of cases the advancing ribbon or band of elevated and reddened integument passes over to a new area, leaving the regions it has traversed tumid, painful, and here and there streaked with rosy lines, patches, or irregular gyrations.

In yet severer types of the malady the intensity of the inflammatory process is such that the epidermis is raised from the tissues below by the free exudation of the serum of the blood. In this way vesicles, or, more commonly, bullæ, develop upon the surface. Bullæ thus formed may be typically perfect, but are often exceedingly irregular in contour, having an appearance which is suggestive of the blistering of a surface by boiling water. The bullæ may be well distended and filled with a perfectly limpid serum. This fluid may, however, in the course of a few days become purulent, the contents in such case drying into crusts. In the severest types of the disease gangrene results from the intensity of the dermatitis, and the loss of tissue which thus occurs is repaired by the processes of granulation and cicatrization.

The migration of erysipelas from one part to another of the surface is sometimes so extensive as to invade from time to time the larger part of the superficies of the body. Erysipelas of this ambulant character may also, after invading the entire surface of the body, be relighted at the point where it first appeared. In other cases this phenomenon of recurrence or reawakening on patches of skin traversed by the disease may be noticed only after moderate extension from a given point. Reddish or rosy-colored islets then appear as new centres of a fresh extension-process upon an integument whose swollen tissues still exhibit the evidences of the prior invasion. In still other cases similar islands of fresh disease are recognized in advance of the elevated edge and tongue-like prolongations which mark the onward progress of the erysipelatous inflammation over areas previously unaffected.

The swelling of the involved tissues is one of the most characteristic features of erysipelas. By this is meant not the tumefaction simply of the superficial portions of the integument, nor the tumefaction which may be measured by the height of the affected above the level of the unaffected skin at the edge of the involved area, but a swelling much more than this, involving the entire skin, and often indeed the subcutaneous tissues, differing, of course, in the extent to which it advances in different cases. In those of severe grade the swelling is enormous, an affected limb assuming the elephantiasic aspect, while the deformity thus induced in the head is fully as great as that seen in the height of confluent variola. In such cases the neighboring ganglia are, as a rule, enlarged and often painful.

It is indeed this swelling which gives to erysipelas of the head and face its peculiar physiognomy. The disorder is apt to find its starting-point in the ear, the side or point of the nose, or one cheek. At this moment it may be possible to recognize the fact that the adjacent mucous membrane is also involved. Thence the disease progresses over the face, and possibly over the scalp also, the resulting tumefaction being occasionally, as already stated, enormous. Thus the eyes are usually closed and sealed by the swollen lids and the orbital depressions are effaced. The lips, enormously pouting and reddened, project from the swollen visage to as great an extent as the tumid ears, which, for similar reasons, depart from the usual plane. The mouth, nares, and eyes alike are covered with mucous secretions, possibly commingled with the contents of bullæ which have formed and broken. Crusts may thus collect near the mucous outlets. The tongue is dry, parched, and cracked, and exhibits a reddish-brown hue. In less severe cases it may be seen to be covered uniformly with a thick yellowish or yellowish-white paste. The fauces and buccal membrane are reddish in color, glazed, and dry.

The patient having this serious form of the malady is indeed in a critical condition. There is usually a coincident coma or delirium. The pulse is either greatly accelerated and full, or thready, fluttering, and destitute of rhythm. The temperature rises to 105° F., and even higher. In this condition a fatal issue may be heralded by collapse, with decadence of the external evidences of the disease, or by the occurrence of blood-filled blebs, or indeed by larger or smaller areas of the surface falling into gangrene. This latter accident may also involve the mucous surfaces, large patches of the buccal membrane, the gums, and even the palate, losing their vitality and showing as greenish-black, insensitive tracts, quite firmly attached to the healthy tissue. These accidents may be of very rapid occurrence, more particularly in the case of individuals prone to exhibit the severest forms of the malady, such as very young infants and those enfeebled by advanced age, by alcoholism, or by any of the cachexiæ.

Other types of erysipelas, chiefly noticeable by reason of their location, are those spreading from the umbilicus, the genital region, the sites of vaccination, of varices of the lower extremities, and the surfaces near the seat of surgical accidents and operations.

The various names which have been, especially by older writers, given to the several expressions of this disorder relate almost exclusively to their external characteristics. Among these may be mentioned—E. ambulans, e. erythematosum, e. bullosum, e. glabrum, e. levigatum, e. miliare, e. oedematosum, e. pemphigoides, e. phlyctenulosum, e. puerperale, e. vaccinale, e. variegatum, e. verrucosum, and e. vesiculosum.

The resolution of erysipelas in favorably terminating cases is accomplished by very gradual amelioration of symptoms. The swelling begins to subside, usually between the third and sixth days. The blebs that have formed then disappear by absorption, bursting, desiccation, or crusting, and subsequent exfoliation. Desquamation of the involved surface may be a prominent or a very insignificant feature. When the patient with erysipelas capitis enjoys a favorable crisis in his disease, there is occasionally noted a very rapid amelioration of the symptoms. The tumefaction speedily subsides, the features become recognizable, and defervescence is complete. Throughout the course of all attacks the febrile process and the erysipelatous blush proceed pari passu with but little deviation of the severity of the one from the intensity of the other.

The complications and sequelæ of the disease are less numerous than they are grave. In erysipelas of the head there is usually a rapid shedding of the hair, though in convalescence the growth of the hair may be restored. An obstinate seborrhoea sicca may, as after variola, linger long afterward upon the scalp; here also, as in other portions of the body, one or many abscesses may form in the subcutaneous tissue after the resolution of the dermatitis; while in phlegmonous erysipelas these abscesses may accompany the disease at its height.

Lymphangitis and adenopathy are common complications of erysipelas, the former betrayed in thickened and often knotted cords, which may be felt radiating from involved areas to neighboring glands. A singular modification is often undergone by the integument affected with erysipelas which has also been the seat of other cutaneous disorders. In this way lupus, psoriasis, chronic eczema, and some of the syphilodermata have been relieved.

Besides the surfaces of the nasal, pharyngeal, and buccal mucous membranes which have been indicated as at times involved by the disease, the inflammatory redness and swelling may extend to the epiglottis, the larynx, and the trachea. Croupous and other forms of pneumonia, pulmonary oedema, and pleuritis have been not rarely noted. In erysipelas of the head the membranes of the brain may inflame and serous effusions distend the ventricles.

The joints may be inflamed either by sympathy or by direct extension of the erysipelatous inflammation to the periarticular tissues, or yet by the occurrence, in or about them, of metastatic abscesses in septicæmic conditions.

The peritoneum may be also acutely or subacutely inflamed in erysipelas, though it is doubtful whether the accident occurs in consequence of the extension of the disease to this membrane from the skin of the abdominal wall. The same may be said of the endocarditis and pericarditis noted by several authors. Of all other complications, it may be said that they can usually be assigned to the occurrence of either septicæmia, or pyæmia, or to the development of metastatic abscesses.

With respect to the eyes, a distinction should be drawn between those attacks originating in deep or superficial affections of the globes and those in which the visual organs are merely involved as by accident in the extension of the disease. In the former case deep orbital abscesses or inflammatory affections of the iris and retina may be followed by erysipelas of the lids or neighboring parts, while in the latter event the issue is more commonly a transitory conjunctivitis, lachrymation, and photophobia, which soon disappear when the disease has declined. The cornea, being unmacerated with pus as in severe variola, commonly escapes perforation.

Erysipelas is a disorder which, without question, produces in a certain proportion of patients a susceptibility to recurrent attacks. This susceptibility, however, is less a systemic tendency to the development of the disease than a peculiar liability to recrudescence originated by chronic local ailments. Thus catarrhal, ulcerative, and other affections of the nasal mucous membrane are particularly apt to originate repeated erysipelatous attacks in the integument covering the nose, and the same is true of the skin in the vicinity of the orifices of fistulous sinuses and varicose veins.

The forms of disease which are often described as instances of chronic erysipelas belong to several classes. There are, first, those in which are observed recurrent attacks of true erysipelas. Second, those in which a chronic eczema or dermatitis produces a circumscribed patch of infiltration in a skin having a lurid reddish hue, which is also the seat of marked subjective sensations, chiefly itching. The well-known forms of chronic eczema erythematosum of the face in middle years or advanced life are commonly, and erroneously, regarded as erysipelatous in character. Third, there is a peculiar dermatitis, of the cheeks chiefly, with regard to whose identity as an erysipelatous affection there is much doubt. The skin is infiltrated in a circumscribed patch, and has a peculiarly glossy red hue. It is essentially a chronic disorder, the affected patch remaining unchanged for months at a time, and then exhibiting aggravation in consequence of accidental exposure to heat or traumatism. These patches may be relics of relapsing forms of erysipelas; and in my experience are more commonly encountered in the subjects of chronic alcoholism.

PATHOLOGY AND MORBID ANATOMY.—The pathological changes exhibited in the erysipelatous skin are those of an exudative process involving the cutaneous and subcutaneous tissues. Nothing specially different from the phenomena observed in a simple dermatitis can be recognized by the microscope alone. Biesiadecki's careful investigations2 certainly do not disclose any such specificity. The epithelia are swollen with serous fluid, and the exudate, though largely serous, contains also the corpuscles recognized in plastic lymph. It is this serum, rapidly invited to the surface by the acuity of the exudative process, which raises the epidermis into the bullæ described above. The nuclei of the bodies recognized in the exudate are evidently in a state of division and consequent multiplication. The epithelia of the rete mucosum are swollen and stretched. The connective-tissue elements in the derma are also swollen, and exhibit reversion to the embryonal state. There is within each a relative increase of protoplasm, as a consequence of which they undergo a species of liquefaction. The blood- and lymph-vessels enlarge and are crowded with corpuscles. The subcutaneous tissue participates in this process, its elements being filled with finely granular cells disseminated or in aggregated masses. The chief peculiarity of this exudation, and of these changes in the tissue-elements where it recurs, is the rapidity with which, when involution is in progress, the fluid is absorbed and the inflammatory elements disappear. When abscess or gangrene complicates the erysipelatous inflammation the changes are not different from those recognized in dermatitis calorica.

The changes noted in the viscera are also of a congestive and inflammatory type. According to Ponfick,3 there is at times a parenchymatous degeneration of the muscular tissues of the large vessels, and of the extremities, as well as of the kidneys, liver, and spleen, the latter organ occasionally undergoing softening. The mucous surfaces of the mouth, larynx, lungs, and alimentary canal have also been found affected with oedema, congestion, and infiltration, rarely terminating in ulcerative changes.

DIAGNOSIS.—The diagnosis of a typical case of erysipelas is so simple that the nature of the malady is often recognized by those unskilled in such matters. It is difficult to mistake for any other affection the circumscribed, swollen, shining, and rosy-reddish patch of skin, accompanied by fever or marked malaise, with adenopathy of near glands, and often with a history of traumatism to which the origin of the disorder may be readily referred.

It is to be distinguished from dermatitis in its various forms (venenata, medicamentosa, phlegmonosa, suppurativa) by its characteristic features, and by the frequent absence in these inflammations of a febrile reaction and of a shining, rosy-red hue of the skin, and by the peculiarities described above of the elevated margin of the erysipelatous area.

Eczema, especially in its chronic erythematous forms, exhibited in the face of adults in middle and later life, is of much slower development, is productive of itching, is ill-defined in contour, and is not accompanied by fever.

Erythema in all its varieties is a purely hyperæmic affection and unaccompanied by fever. In erythema multiforme there is an exudative process by reason of which various papules, nodosities, and at times even bullæ, appear upon the surface. None of them, however, are accompanied by a diffused area of redness spreading at the periphery. All of its lesions are circumscribed, and rarely affect the face.

Pemphigus could only be mistaken for the form of erysipelas bullæ, but its lesions do not rise from a broadly inflamed area; they rather have attended with each a distinct individual halo when the integument from which they spring is at all congested. They are also rarely accompanied by a febrile process.

Scarlatina, though a febrile affection, is readily distinguished from erysipelas by the appearance of its exanthem, symmetrically and generally developed over the entire surface of the body, or progressively and symmetrically from the upper to the lower segment of it. The exanthem has also a dull scarlet color or the boiled lobster hue, differing thus from the rosy-red and shining patch of erysipelas.

Urticaria also is often of symmetrical development, is rarely accompanied by fever, and is characterized by typical wheals, which, however closely packed together, never have the smoothness of the surface affected with erysipelas.

PROGNOSIS.—The prognosis of a simple case of uncomplicated erysipelas occurring in an individual in fair health and possessed of a reasonable degree of vigor may be regarded as favorable. Even in the weakness of infancy a large area may be involved in the disease and a high degree of fever be aroused without alarming results.

Erysipelas should, however, always be regarded as a serious disease or a serious complication of any existing malady. It is often a grave feature in surgical injuries. Erysipelas involving the entire surface of the face and head is always a formidable affection. In the puerperal state it is dreaded by every accoucheur.

All these circumstances are rendered more portentous by the existence of the disorder as a complication of any other grave malady, or by its occurrence among the subjects of alcoholism, struma, phthisis, or various other cachexias, and among the aged. Occurring in epidemic form among the inmates of prisons, camps, and hospitals, the mortality of the disease may be increased tenfold.

TREATMENT.—The prophylaxis of erysipelas is that of all contagious diseases. It involves isolation of the affected individual, disinfection of body- and bed-clothing before the latter are again employed upon the persons of others, and destruction by fire of all dressings which have been in contact with the integument.

The hygienic management of the patient is not to be neglected. The complete ventilation of the sick chamber is to be secured, and its temperature uniformly sustained at a point between 65° and 70° F.

The general treatment of the sufferer need not greatly differ from that commonly pursued in the febrile state by modern therapeutists. There is but little confidence to-day in the methods by venesection and purgation, upon which at one time reliance was placed. Cool or cold water may be freely employed when there is hyperpyrexia, either by general bathing or by wrapping the patient in sheets dipped in and wrung out of the same fluid. The results are favorable as regards the bodily temperature, and are not productive of danger, though water thus applied has no effect upon the local disorder of the skin. Iced or cool water, by the ice-bag or compresses, is specially indicated as a topical application for the head when there is delirium or other indication of disturbance of the cephalic centres, irrespective of the invasion of the scalp and face by the erysipelatous inflammation. The sulphate of quinia in full doses is indicated especially when there is any tendency to remittence in the febrile accessions, but is not known to possess any power to cut short the disease. In many cases of erysipelas the febrile condition is readily managed by the administration of the simpler remedies found grateful to the palate of the sufferer, such as iced, acidulated, and effervescing draughts, with perhaps the employment of the spiritus Mindereri or the spirit of nitrous ether. In other cases the mineral acids can be substituted with advantage for the latter. With many American physicians it is customary to add to these remedies the tincture of the root of aconite, with a view to its effect upon the pulse.

Few internal remedies, however, have in this country enjoyed as much popularity with the profession in the treatment of erysipelas as the muriated tincture of iron in full doses. Its use, first suggested for this purpose by Bell in 1851, has here steadily gained in favor since its general adoption. It is well to give it in doses of not less than 20 or 30 drops, repeated every two or three hours, diluted with water. When there is high fever, and especially if the secretion of urine is scanty, the following formula will be found valuable:

Rx.Tr. Ferri Chloridi;
Sp. Ætheris Nitrosi;
Glycerinæ aa.fl. drachm i. M.

S. A teaspoonful in water every three hours.

This preparation of iron certainly seems, in many cases, to shorten the disease, but, per contra, it is to be remembered—first, that in many other cases it has been found to exercise no control whatever over the severest manifestations of the disease; second, that in other countries, especially in Germany, where it is rarely employed, the mortality from the disease is no greater than elsewhere.

The widest difference in practice has obtained relative to the local treatment of the affection. They who have had the fortitude to content themselves with watching the evolution of the specific dermatitis, merely protecting the skin by dusting over it a simple powder or leaving it covered with a cold compress, have certainly no worse results to tabulate than those who entertain a belief in the efficacy of the abortive treatment of the local disorder.

No remedies, locally applied, can be recognized as certainly possessing the power to cut short the inflammation. Those which enjoy the highest reputation for topical employment are saturated solutions, hot and cold, of the hyposulphite of sodium, of boracic acid, and of the bicarbonate of sodium; salicylic acid; iodoform in powder; and, quite lately, resorcin. Hot fomentations of the erysipelatous patch are in general most grateful to the patient, and with these an opiate and astringent effect can be obtained, as by a hot lead and opium wash or by solutions of the sulphate of iron or of alum and tannin. Useful methods of applying these are by the medium of borated cotton, oakum, tow, or spongiopiline, covered with oiled silk or the Lister protective material.

Other medicaments which have enjoyed favor in the topical treatment of the disease are lime-water and linseed oil (carron oil), sulphur in powder, carbolic acid, camphor, the oil of turpentine, collodium, cataplasms and ointments containing mercury, lead, zinc, tar, and tannin.

Respecting the measures adopted with a view to checking the extension of the disease at the periphery of the patch, the belief in such a possibility has been wellnigh abandoned. For this purpose the nitrate of silver, caustic potash, tincture of iodine, and similar substances have been boldly and broadly applied, alike over the sound and affected integument, with the production of an artificial dermatitis intended to supplant that which was previously in progress. Again and again has the local inflammation transgressed these artificial limits; and when they have been by it apparently respected there has been little ground for believing that the result was due to the treatment pursued. Inasmuch as the disease is often self-limited and distinctly limited in its progression over the surface, it is manifestly difficult to determine that its limitation in any given case is the result of topical agencies. These agencies have, moreover, the marked disadvantage of adding their irritative effects to those incidental to the dermatitis.

The surgical treatment of erysipelas invading special regions of the body or the deeper tissues is a matter of importance. Free incisions are requisite for the liberation of pus, and all abscess cavities should be treated antiseptically and stuffed with iodoform or resorcin. Great tension of the lids demands free incisions in the long diameter of either, and the same surgical procedures are often demanded in erysipelas of the scrotum or of the labia in the female. Gangrene and sloughing are to be treated in accordance with the principles recognized as important in the management of these accidents in general.

The mouth when involved may be benefited by gargles containing the chlorate of potassium, alum, tannin, the compound tincture of cinchona, or by the use of the spray with a saturated solution of boracic acid in rosewater. Kaposi lays stress, in all cases of erysipelas of the face, upon the importance of searching for and evacuating all dental abscesses and pustules seated upon the Schneiderian membrane. Crusts in the nasal cavity are to be soaked with vaseline and removed by washing, their re-formation being prevented by the insertion of small tampons smeared with a bland ointment or oily fluid. Abscesses in other portions of the body, not suspected as being etiologically significant, are to be carefully searched for and emptied, whether occurring about the anus, the genitals, or the legs.

Subcutaneous injections of carbolic acid and other antiseptic solutions have not been rewarded by such results as to establish in any degree their special efficacy.

In all ordinary cases the expectant treatment recommended by Zuelzer is abundantly to be commended. The inflamed tissue is to be dusted with finely-powdered starch, and protected by a layer of soft cotton-wool which exercises a moderate degree of pressure upon it. Antiseptically, the highest ends are thus reached.

The diet of the patient should consist of animal broths, soups, milk, and eggs, with a view to the reparation of the waste incidental to the febrile process. Stimulants are to be freely used in all asthenic conditions. In convalescence the warm water and soap bath is to be employed, followed by dusting of the surface with starch powder or by inunction with vaseline.
