The constitutional symptoms depend upon the underlying malady, and may of course vary with its character. Thus we may have the symptoms of simple diarrhoea, gastro-enteritis, or entero-colitis on the one hand, and of tuberculosis and other diseases elsewhere enumerated on the other. Cachectic children, especially in asylum and hospital practice, lose flesh, and their skins become harsh, dry, and inelastic from loss of fluids (Meigs and Pepper). The genitalia, the anus, and the adjacent parts become eroded by the acridity of the discharges, and then become covered with the growth.
The disease rarely lasts longer than eight days in strong children that can be well cared for. It may continue indefinitely, on the other hand, in cachectic children; that is to say, for several months or until the patient succumbs, as may be. Death occurs usually from the causal disease, and not as a result of the morbid condition of the mouth.
DIAGNOSIS.—In the Infant.—Examination of its mouth to detect the cause of the child's inability to nurse reveals congestion of the mucous membrane, intense and often livid in severe cases. It is first noticed at the extremity of the tongue. When the congestion is general it is darkest in the tongue. This livid congestion may extend over the entire visible mucous membrane, save upon the hard palate, where it is tightly adherent to the periosteum, and upon the gums, where it is rendered tense by the approach of erupting teeth. The papillæ at the tip and sides of the tongue are very prominent. Sometimes the organ is quite dry, even sanious, while it is painful to the touch. The reaction of the secretions of the mouth is acid instead of alkaline, and the parts are hot and very sensitive.
Two or three days later the circular milky-white or curdy spots or slightly prominent and irregularly-shaped flakes or patches may be seen on the upper surface of the tongue toward the tip and inside the lips and the cheeks, especially in the grooves connecting gums and lips and gums and cheeks. The surrounding mucous membrane is unaltered in mild cases, and there is no evidence of other local disorder or of any constitutional involvement. In severe cases the entire mucous membrane is dry and deeply congested.
The affection can be positively discriminated from all others by microscopic examination of the deposit, which reveals the presence of the cryptogam described.
TREATMENT.—In infants, artificial nourishment, whether with milk of the lower animals or prepared food of whatever composition, should be given up, if possible, and a wet-nurse be supplied. If this procedure be impracticable, the least objectionable mode of preparation of cow's milk should be employed (and this will vary with the practice of the physician), and the utmost circumspection should be maintained in securing the cleanliness of the vessels in which it is prepared, the bottle from which it is given, and the nipple which is placed in the child's mouth. Should the sugar and casein in the milk appear to keep up the disease, weak soups may be substituted for the milk diet until it has subsided. Weiderhofer advises artificial nourishment, by way of a funnel inserted in the nasal passages, in case the child should refuse to swallow. Deglutition is excited in a reflex manner when the milk or other fluid reaches the pharynx.9

The local treatment should consist in careful removal of the patches from time to time—say every two or three hours—with a moistened soft rag. This must be done without roughness of manipulation. In addition to this, the parts may be washed or painted every hour or so with an alkaline solution for the purpose of neutralizing the acidity of the fluids of the mouth. For this purpose borax is most generally used, in the proportion of twenty grains to the ounce of water or the half ounce of glycerin. Sodium bicarbonate or sodium salicylate may be substituted for the sodium borate. The use of honey in connection with the drug is calculated to promote acidity by fermentation of its glucose, and is therefore, theoretically, contraindicated.
Adults may use washes, gargles, or sprays of solutions of sodium borate or of sodium bicarbonate.
The constitutional treatment in each case must be adapted to the nature of the underlying malady which has favored the local disease, with resort in addition to the use of quinia, iron, wine, spirit, and beef-essence. The hygienic surroundings should be made as sanitary as possible.
