What do you understand by erythema intertrigo?

Erythema intertrigo is a hyperæmic disorder occurring on parts where the natural folds of the skin come in contact, and is characterized by redness, to which may be added an abraded surface and maceration of the epidermis.

Describe the symptoms of erythema intertrigo.

The skin of the involved region gradually becomes hyperæmic, but is without elevation or infiltration; a feeling of heat and soreness is usually experienced. If the condition continue, the increased perspiration and moisture of the parts give rise to maceration of the epidermis and a mucoid discharge; actual inflammation may eventually result.

What is the course of erythema intertrigo?

The affection may pass away in a few days or persist several weeks, the duration depending, in a great measure, upon the cause.

Mention the causes of erythema intertrigo.

The causes are usually local. It is seen chiefly in children, especially in fat subjects, in whom friction and moisture of contiguous parts of the body, usually the region of the neck, buttocks and genitalia, are more common; in such, uncleanliness or the too free use of soap washings will often act as the exciting factor. Disorders of the stomach or intestinal canal apparently have a predisposing influence.

What treatment would you advise in erythema intertrigo?

The folds or parts are to be kept from contact by means of lint or absorbent cotton; thin, flat bags of cheese cloth or similar material partly filled with dusting-powder, and kept clean by frequent changes, are excellent for this purpose, and usually curative. Cleanliness is essential, but it is to be kept within the bounds of common sense. Dusting-powders and cooling and astringent lotions, such as are employed in the treatment of acute eczema (q. v.), can also be advised. The following lotion is valuable:—

Exceptionally a mild ointment, alone or supplementary to a lotion, acts more satisfactorily.

In persistent or obstinate cases attention should also be directed to the state of the general health, especially as regards the digestive tract.
