Definition And Description

This is an affection of the skin that sometimes arises in consequence of prolonged contact of two cutaneous surfaces. It is more frequent in infancy and at an advanced age, than during the intermediate periods of life, and occurs more especially in those possessed of a superabundance of adipose tissue. In fat children the skin of the abdomen, particularly in the inguinal regions, is frequently in contact with that of the thighs. In these cases the cutaneous secretions, insensible perspiration, etc., instead of passing off in a state of vapor, remain fluid. This fluid undergoes decomposition, resulting in the formation of certain highly irritating substances. The epithelium of the part being moist and macerated, affords little protection against these acrid bodies, and they consequently, in a short time, provoke an intense congestion, accompanied sometimes with a certain amount of thin serous exudation. If this condition is unrelieved the epidermis becomes eroded, and even ulcerations may form and extend through the entire thickness of the skin. The ulcerated parts secrete a thin, sero-purulent matter, which mingles with the other cutaneous secretions. The affection is not always confined to the parts mentioned, but may occur whenever two cutaneous surfaces are in apposition, the favorite locations being the fold between the thigh and the genitals, and under the chin in fat, short-necked babies.

In stout, elderly men, but more frequently in elderly women, intertrigo is also met with, the pendulous breasts and abdomen being in almost perpetual contact with the surfaces that they overhang.

Diagnosis

The affection is so common that no difficulty is ever likely to arise in its diagnosis. Occasionally, however, it is masked by an Eczema, coming on in those predisposed to that affection, as a consequence of the irritation from the Intertrigo.

Prognosis

Favorable.

Treatment

In mild cases little more is required than the separation of the parts by the insertion of a fold or two of linen, dusted over with some inert absorbent powder, such as equal parts of starch and lycopodium. The affected skin should be frequently washed with a little tepid water, and thoroughly dried before the application of the powder. In more severe cases, astringent applications, containing a little tannin, may be required. If ulceration be present, decided stimulants may be used, as solutions of Sulphate of Zinc, Nitrate of Silver, etc., in addition to the means already indicated. The principal indications for treatment in all cases are to keep the parts clean and dry, and unless these are attended to, even after the affection is controlled, there is every probability of a relapse.

In addition to the foregoing, the following drugs are sometimes of service: Calcii Carbonas, 34; Bismuthi Subnitras, 33; Collodion, 46; Sodii Boras, 74; Zinci Carbonas, 116.
