Strong, well-fed children are as likely to develop stomatitis as are those who are weakly and ill fed.

The disease is caused by infection and is contagious. Just what the infection is we do not know; we do, however, know that children whose mouths are carefully cleaned after each feeding do not have sore mouths of this character. When cleaning the mouth care must be observed not to injure the tender mucous membrane.

Treatment.—As soon as the condition is observed mouth-washing should be systematically and thoroughly carried out. After each feeding the mouth should be washed with a saturated solution of boric acid in boiled water. (See page [626].)

It is not necessary to use any further treatment, as a rule. Patients recover in four to eight days. Strict attention to cleanliness, however, is imperative. The feeding bottle and nipple, or the mother's nipple, if breast fed, must be kept scrupulously clean.

The feeding of these children is sometimes a problem for a day or two, because, as stated above, of the soreness of the mouth. This is best overcome by feeding the baby with a spoon. If breast fed, it is necessary to pump the milk and then feed with the spoon. Children will take the milk better if it is fed cold. Cold boiled water is largely taken and is good for them at this time.

Treatment for Ulcers in Mouth.—The ulcers should be touched with a camel's-hair brush which has been dipped into finely powdered burnt alum. If a stronger caustic is necessary, the solid stick of nitrate of silver may be used.

A mouth wash may also be used in the ulcerative cases, composed of the peroxide of hydrogen diluted with two parts of water. If this is used wash the mouth out afterward with plain, cool, boiled water. The peroxide mouth wash can be used four or five times daily.

In addition to the mouth washing in the ulcerative cases it is advisable to use internally chlorate of potash. The druggist should be requested to make a two-ounce saturated solution, and of this you can give one-half teaspoonful, largely diluted with cool water, every hour during the day for the first twenty-four hours, then every two hours until marked improvement is shown, when it can be further reduced by lengthening the interval between doses.

SPRUE—THRUSH

Sprue is a form of sore mouth. It is seen only during the first six months of life, as a rule. It affects the mucous membrane of the mouth; it appears in the form of small white spots that look like drops of curdled milk. They are on the inner surface of the cheek and may be all over the mouth, and on the tongue. The spots are firmly attached, and if forcibly removed the mucous membrane will bleed.
