There are no special complications. The accompanying stomatitis is usually a gingivitis simply, and is apt to be circumscribed when more extensive.
There are no sequelæ. Sometimes labial herpes or similar ulcerations follow, which are likewise sore and painful.
DIAGNOSIS.—The isolated patches of the discrete form are usually sufficiently characteristic to establish the diagnosis.
In children the gums are usually seen to be congested, swollen, moist, and glistening. Sometimes they are even sanious. This condition is deemed of great importance in cases of small, solitary aphthæ concealed in the sinus between gums and lips (Rilliet).
Confluent aphthæ may be mistaken for ulcerative or ulcero-membranous stomatitis, especially when the emanations from a coated tongue exhale a disagreeable or fetorous odor.
From thrush—with which it is most frequently confounded—it is to be discriminated by the absence, upon naked-eye inspection, of the peculiar curdy-like exudations to be described under the appropriate section, and under microscopic inspection by the lack of the peculiar thrush-fungus (Oïdium albicans).
PROGNOSIS.—Recovery is usually prompt in discrete cases, but relapses are not infrequent. In confluent cases recovery is dependent upon the character of the constitutional disorder by which the local disease has been caused or with which it is associated, and is therefore much slower.
The disease is grave in certain epidemic confluent forms, such as are described as occurring in Holland and elsewhere under conditions alluded to. Parturient women under such circumstances occasionally succumb to the typhoid condition into which they are thrown. When following measles there is some danger of laryngitis, and the case becomes grave. Oedema of the larynx is sometimes produced.
TREATMENT.—Very simple treatment suffices in the discrete form of the disease. A mild antacid, or even an emetic, may be indicated when there is gastric derangement or disturbance; or a mild laxative when the patient is costive. Castor oil, rhubarb, or magnesia may be given, followed, if need be, by an astringent if diarrhoea should occur. A little opium may be administered if requisite. The diet should be quite simple and unirritating. Cold milk is often the very best diet, especially while the mouth remains quite sore.
Topical treatment in the milder cases may be limited to simple ablutions, by rinsing or by spray, with water, cold or tepid as may be most agreeable to the patient. A little opium may be added when the parts are painful or tender. In severer cases an antiseptic wash may be substituted, as the sodium sulphite or hyposulphite, thirty grains to the ounce, creasote-water, or the like.
