Part 50

If the sores are slow to heal, the ulcerated surfaces may be touched once or twice daily with some astringent, such as solution of silver nitrate (ten grains to the ounce), or, if that be objectionable, with alum, tincture of iodine, or iodoform.

Prompt extraction of loose teeth and of loose fragments of necrosed bone is requisite.

Stomatitis Gangrenosa.

DEFINITION.--A non-contagious, deuteropathic inflammation of the interior of the mouth, almost invariably unilateral, and characterized by a peculiar gangrenous destruction of all the tissues of the cheek from within outward.

SYNONYMS.--Gangrenous stomatitis; Gangrena oris; Grangrenopsis; Cancrum oris; Stomato-necrosis; Necrosis infantilis; Gangrene of the mouth; Gangrenous erosion of the cheek; Noma; Buccal anthrax; Aquatic cancer; Water cancer; Scorbutic cancer; Sloughing phagedæna of the mouth.

HISTORY.--The most important work upon the subject was published in 1828, from the pen of Dr. A. L. Richter, whose accurate historical account of the disease was in great part reproduced, with additions thereto, by Barthez and Rilliet in their Treatise on the Diseases of Infants, Paris, 1843, and quoted by nearly all subsequent writers on the {339} theme. From these records it appears that the first accurate description of the affection was given in 1620 by Dr. Battus, a Dutch physician, in his Manual of Surgery. The term aquatic cancer, water-kanker, bestowed on it by van de Voorde, has been generally followed by the physicians of Holland, although van Swieten (1699) properly designated it as gangrene. J. van Lil termed it noma, as well as stomacace and water-kanker, and cited a number of Dutch physicians who had observed its epidemic prevalence. The majority of more recent observers, however, deny its epidemic character.

Of Swedish writers, Lund described it as gangrene of the mouth; Leutin, under the name of ulocace. In England, Boot was the first to write of gangrene of the mouth, and was followed by Underwood, Symmonds, Pearson, S. Cooper, West, and others.

In France it has received great attention. Berthe described it as gangrenous scorbutis of the gums; Sauvages (1816) as necrosis infantilis. Baron in 1816 published a short but excellent account of a gangrenous affection of the mouth peculiar to children; and Isnard presented in 1818 his inaugural thesis on a gangrenous affection peculiar to children, in which he described, simultaneously, gangrene of the mouth and gangrene of the vulva. Then followed Rey, Destrees (1821), Billard (1833), Murdoch, Taupin (1839), and others, until we reach the admirable description by Barthez et Rilliet, from which the present historical record has been chiefly abstracted.

German physicians likewise have largely studied the subject. De Hilden, A. G. Richter, C. F. Fischer, Seibert, and many others preceded A. L. Richter, whose important contribution to the literature and description of the disease has been so highly extolled by Barthez and Rilliet.

In America the disease has been best described by Coates, Gerhard, and Meigs and Pepper, all of Philadelphia.

ETIOLOGY.--Almost exclusively a disease of childhood, gangrenous stomatitis is exceedingly rare in private practice, and very infrequent at the present day even in hospital and dispensary practice. Lack of hygienic essentials of various kinds, impoverishment, long illnesses, and debilitating maladies in general are the predisposing causes. It is sometimes endemic in hospitals and public institutions, but rarely, if at all, epidemic. It is not generally deemed contagious, though so considered by some writers. It appears to have been more frequent in Holland than elsewhere, to be more frequent in Europe generally than in the United States, and now much less frequent in the United States than formerly. To recognition of the predisposing causes and to their abolition and avoidance may probably be attributed its diminished frequency all over the world. Though attacking children only as a rule, it has been observed in adults (Barthez et Rilliet, Tourdes, Vogel). Nurslings are not liable to the disease. Though occurring occasionally earlier in life, the greatest period of prevalence is {340} from the third to the fifth or sixth year of age, and thence, with diminishing frequency, to the twelfth and thirteenth years. It is probably equally frequent in the two sexes, though the majority of authors have described it as more frequent in females.

Healthy children are not attacked. Even in delicate children it is so rarely idiopathic that this character is utterly denied it by many observers. The disease which it follows, or with which it becomes associated, may be acute or chronic. According to most writers, it occurs with greatest frequency after measles. It follows scarlatina and variola much less often. It is observed likewise after whooping cough, typhus fever, malarial fever, entero-colitis, pneumonitis, and tuberculosis. Excessive administration of mercury has been recognized as an exciting cause, some cases of mercurial stomatitis progressing to gangrene.

According to Barthez et Rilliet, acute pulmonary diseases, and especially pneumonia, are the most frequent concomitant affections, and are usually consecutive.

SYMPTOMATOLOGY, COURSE, DURATION, TERMINATIONS, COMPLICATIONS, AND SEQUELÆ.--The disease usually becoming manifested during other disease, acute or chronic, or during convalescence therefrom, there are no special constitutional symptoms indicating its onset. Hence considerable progress may be made before its detection. The earliest local characteristic symptom distinguishing gangrenous stomatitis is a tense tumefaction of one cheek, usually in proximity to the mouth. The lower lip is generally involved, thus rendering it a matter of difficulty to open the mouth. This tumefaction in some instances progresses over the entire side of the face up to the nose, the lower eyelid, and even out to the ear in one direction, and down to the chin, and even to the neck, in the other. Before the parts become swollen externally, ulceration will have taken place to some extent in the mucous membrane, but usually without having attracted special attention, the subjective symptoms having been slight. A gangrenous odor from the mouth, however, is almost always constant. Its presence, therefore, should lead to careful investigation as to its seat and cause. The gums opposite the internal ulcer become similarly affected in most instances, and undergo destruction, so that the teeth may become denuded and loosened, and even detached, exposing their alveoli. The bodies of the maxillary bones suffer in addition in some instances, and undergo partial necrosis and exfoliation.

It is maintained (Löschner, Henoch) that in some instances there is no involvement of the mucous membrane until the ulcerative process has reached it from the exterior.

The tumefied portions of the check and lip are pale, hard, unctuous, and glistening. They are rarely very painful, and often painless. On palpation a hard and rounded nodule one or two centimeters in diameter can be detected deep in the central portion of the swollen cheek.

From the third to the sixth day a small, black, dry eschar, circular or oval, becomes formed at the most prominent and most livid portion of the swelling, whether cheek or lip. This gradually extends in circumference for a few days or for a fortnight, sometimes taking in almost the entire side of the face or even extending down to the neck. As it enlarges the tissues around become circumscribed with a zone intensely red. The internal eschar extends equally with the external one. Eventually, the {341} eschar separates, in part or in whole, and becomes detached, leaving a hole in the cheek through which are seen the loosened teeth and their denuded and blackened sockets.

During this time the patient's strength remains tolerably well maintained, as a rule, until the gangrene has become well advanced. Intelligence usually remains good. Many children sit up in bed and manifest interest in their surroundings. Others lie indifferent to efforts made for their amusement. Some exhibit insomnia and delirium. The pulse is small and moderately frequent, rarely exceeding 120 beats to the minute until near the fatal close, when it often becomes imperceptible. Appetite is often well preserved, unless pneumonia or other complications supervene, but thirst is often intense, even though the tongue remain moist. The desire for food sometimes continues until within a few hours of death. Toward the last the skin becomes dry and cold, diarrhoea sets in, emaciation proceeds rapidly, collapse ensues and death.

Death usually occurs during the second week, often before the complete detachment of the eschar--in many instances by pneumonia, pulmonary gangrene, or entero-colitis. Some die in collapse, which is sometimes preceded by convulsions. When the eschars have become detached, suppuration exhausts the forces of the patient, and death takes place by asthenia.

The complication most frequent is pneumonia, and the next entero-colitis. Gangrene of the lungs, of the palate, pharynx, or oesophagus, of the anus, and of the vulva, may supervene. Hemorrhage from the facial artery or its branches has been noted as an exceptional mode of death (Hueber), the rule being that the arteries in the gangrenous area become plugged by thrombi, and thus prevent hemorrhage.

Recovery may take place before the local disease has penetrated the cheek--indeed, while the mucous membrane alone is involved. In recent instances, however, the disease does not subside until after the loss of considerable portions of the cheek, and the child recovers with great deformity, not only from loss of tissue in the cheek and nose, but from adhesions between the jaws and the cheek.

PATHOLOGY AND MORBID ANATOMY.--Gangrenous stomatitis always involves the cheek, almost always that portion in proximity to the mouth. It is almost invariably unilateral. Either side seems to be equally liable. Both sides suffer only, it is contended, when the gangrene is limited in extent, confined to the mucous membrane, and occupies the sides of the frenums of the lips (Barthez et Rilliet). It usually if not invariably begins in the mucous membrane, as a phlyctenular inflammation, which undergoes ulceration, followed by gangrene, immediately or not for several days, and then becomes covered with a more or less brownish-gray eschar. The ulceration of the mucous membrane is occasionally preceded by an oedematous condition of the cheek externally, similar to that sometimes observed in ordinary ulcerous stomatitis; but this is not the characteristic circumscribed, tense infiltration observed later. This ulceration is situated most frequently opposite the junction of the upper and lower teeth. Sometimes it proceeds from the gingivo-buccal sulcus of the lower jaw, sometimes from the alveolar border of the gums. It extends in all directions, and often reaches the lower lip. From three to sixteen days may be consumed in these extensions. The {342} surrounding mucous membrane becomes oedematous. The ulceration soon becomes followed by gangrene, sometimes within twenty-four hours, sometimes not for two or three days, and exceptionally not for several days. The ulcerated surfaces bleed readily, change from gray to black, and become covered with a semi-liquid or liquid putrescent detritus. They are sometimes surrounded by a projecting livid areola, which soon becomes gangrenous in its turn. The shreds of mortified membrane, though clinging a while to the sound tissues, are easily detached, and often drop spontaneously into the mouth. Meanwhile, there is abundant salivation, the products of which pour from the mouth, at first sanguinolent, and subsequently dark and putrescent and mixed with detritus of the tissues. Large portions of the gums, and even of the mucous membrane of the palate, may undergo destruction within a few (three to six) days. The gangrenous destruction of the gums soon exposes the teeth, which become loose and are sometimes spontaneously detached. Thence the periosteum and bone become implicated and undergo partial denudation and necrosis, and portions of necrosed bone become detached if the patient survives. The characteristic implication of the exterior of the cheek becomes manifest from the first to the third day, but occasionally not until a day or two later. A hard, circumscribed swelling of the cheek or cheek and lip occurs, sometimes preceded, as already intimated, by general oedematous infiltration. The surface is tense and unctuous, often discolored. In its central portion is an especially hard nucleus, one to two centimeters or more in diameter. Gangrene often takes place at this point from within outward at a period varying from the third to the seventh day or later. The skin becomes livid, then black; a pustule is formed at the summit of the swelling, which bursts and discloses a blackened gangrenous eschar from less than a line in thickness to the entire thickness of the cheek beneath. The area of gangrene gradually extends. The dead tissues become detached, and a perforation is left right through the cheek, through which are discharged saliva and detritus. Meanwhile, the submaxillary glands become swollen and the surrounding connective tissue becomes oedematous. In some instances, however, no change is noticeable in these glands.

Examinations after death have shown that thrombosis exists for some distance around the gangrenous mass. Hence the rarity of hemorrhage during the detachment of the eschar.

DIAGNOSIS.--In the early stage of the disease the main point of differential diagnosis rests in the locality of the primitive lesion, the mucous membrane of the inside of one cheek. Subsequently there is the gangrenous odor from the mouth; the rapid peripheric extension of the local lesion, which acquires a peculiar grayish-black color; its rapid extension toward the exterior of the cheek or lip; the tumefaction of the cheek, discolored, greasy, hard, surrounded by oedematous infiltration, and presenting a central nodule of especial hardness; then the profuse salivation, soon sanguinolent, subsequently purulent and mingled with detritus of the mortified tissues. Finally, the eschar on the exterior of the swollen cheek or lip leaves no doubt as to the character of the lesion. From malignant pustule it is distinguished by not beginning on the exterior, as that lesion always does (Baron).

PROGNOSIS.--The prognosis is bad unless the lesion be quite limited {343} and complications absent. At least three-fourths of those attacked perish; according to some authorities fully five-sixths die. The objective symptoms of the local disease are much more important in estimating the prognosis than are the constitutional manifestations, the vigor of the patient, and the hygienic surroundings, although, as a matter of course, the better these latter the more favorable the prognosis. Prognosis would be more favorable in private practice than in hospital or asylum service.

TREATMENT.--Active treatment is required, both locally and constitutionally. Local treatment is of paramount importance, and alone capable of arresting the extension of the process of mortification. The topical measure in greatest repute is energetic cauterization with the most powerful agents, chemical and mechanical--hydrochloric acid, nitric acid, acid solution of mercuric nitrate, and the actual cautery, whether hot iron, thermo-, or electric cautery. The application of acids is usually made with a firm wad or piece of sponge upon a stick or quill, care being taken to protect the healthy tissues as far as practicable with a spoon or spatula. After the application the mouth is to be thoroughly syringed with water to remove or dilute the superfluous acid. Hydrochloric acid has been preferred by most observers.

As these cauterizations must be energetic to prove effective, anæsthesia ought to be induced. Should ether be employed for this purpose, hydrochloric acid or the acid solution of mercuric nitrate would be selected of course.
