Child's butt itchy at night

Children may have itchy buttocks at night, which is most likely caused by tinea cruris. Tinea cruris is a relatively common skin disease and also a disease that can have a great impact on children's skin health. Of course, due to the strong itching sensation, it will inevitably have a certain impact on the child's mental health. Next, I will introduce you to the relevant knowledge about tinea cruris!

1. Causes

It is often caused by Epidermophyton floccosum, Trichophyton mentagrophytes, Trichophyton rubrum, etc. Sometimes, Candida albicans also invades the groin area and presents as erythematous desquamative patches with papulovesicles on the edges.

This disease is prone to occur in warm and humid seasons, and men with excessive sweating are particularly susceptible to it. People in special occupations, such as car drivers and those who sit for long periods of time, are also prone to the disease.

2. Clinical manifestations

It often occurs on the skin of the thigh opposite the scrotum, on one side or both sides, and is mostly annular or semi-annular patches. Initially, a small patch of erythema appears on the inner side of the upper thigh, with desquamation on it, and gradually expands and spreads to the surrounding area, with clear borders and papules, blisters and scabs on it. The central part can heal itself, with pigmentation or desquamation. Over time, the local skin will become infiltrated, thickened and lichenified, often accompanied by itching. In severe cases, it often extends to the inner thigh, perineum or around the anus, and the lower edge is usually clear. Sometimes it can affect the scrotum, base of the penis, etc.

Treatment

Treat tinea corporis. Because the skin of the pubic area is more delicate, care should be taken not to use overly irritating lotions to avoid irritating the skin. Generally, compound resorcinol lotion or 1% econazole or clotrimazole cream can be used. 2% miconazole, bifonazole, ketoconazole, and terbinafine cream can also be used.

For stubborn and relapsing cases, itraconazole, terbinafine, etc. can be taken orally for a short period of time.

4. Prevention

Because this disease is contagious and mostly transmitted through contact. Therefore, in order to avoid the spread of tinea cruris, keep yourself clean and avoid having improper sexual relations with others. Do not use other people's underwear, panties and toiletries. Change your underwear frequently, keep your vulva clean, and wash and dry your clothes and quilts frequently. Obese people should take a bath frequently and apply face powder, etc. Try to stay dry and wear loose fitting underwear.
