This very common affection in infancy, is characterized by the appearance of small, round, white vesicles on the interior of the mouth and over the tongue, which, if not checked, run together, forming patches, producing a superficial ulceration of the mucous membrane of the mouth and throat. There is of course difficulty of nursing and swallowing, and generally, a deranged state of the stomach and bowels. Where the attack is severe, and the ulceration extensive, there is more or less fever, pain, restlessness, etc.
There is another variety of aphthae, sometimes mistaken for thrush. It consists at first of small points or patches of curdy matter on the surface of the membrane, and generally easily wiped away with a cloth. In severe cases, blood may exude from the mucous membrane at these points.
The prominent cause is a constitutional taint. It is also frequently produced by improper food in those who are fed with the bottle or spoon.
If the inflammation is not very severe, equal parts of borax and loaf sugar may be mixed dissolved in water and applied to the mouth three or four times a day; or borax and honey may be mixed and applied in the same way, or the mouth may be washed with a mixture made by dissolving a few grains of borax in a tea-cupful of water.
Mercury should be given two globules or a powder twice a day, when the disease first makes its appearance, especially if there is salivation and ulceration. Sulphur should follow Mercury at the same intervals, if the latter fails to effect a cure in three or four days.
