Tinea corporis, as the name implies, is a skin disease that occurs in the femur and can develop in the perineum, around the anus, on the inner thighs, and on the buttocks, hence the name “jock itch”. Both men and women can get it, but more men than women and more middle-aged than young people. The reason why ringworm is so common in middle-aged and elderly people, car drivers, and sedentary people is because they are sedentary for a long time and have less activity, so the ventilation in the femur is not good, sweat does not evaporate easily, and the humidity and temperature are high, which is conducive to the growth of fungi, so the pathogenic bacteria that cause skin infections quickly multiply and ringworm occurs in the skin.
The cause of ringworm: The germs that cause ringworm are epidermophytes such as Trichophyton rubrum, Flocculent epidermophytes and Plaster-like Trichophyton. These bacteria use skin keratin as a nutrient to survive and reproduce. In the humid and warm conditions are most suitable for its survival and spread, and the femur is a good environment for its growth, survival, and reproduction, once the following sources of infection are available.
1, from the vast natural world of ringworm bacteria.
2, contaminated household items (such as slippers, bath tubs, bath towels, etc.
3, impure sexual behavior, ringworm is also classified as a broadly defined sexually transmitted disease.
4.Self-transmission-having ringworm, nail fungus can plant itself within the strand.
5. Contact with animals such as dogs and cats.
6.Trauma can cause infiltration of ringworm bacteria and ringworm can occur.
The characteristics of ringworm are as follows: It occurs on one or both sides of the skin of the groin. When ringworm is first acquired, it is a slightly elevated erythema, papule or blister with clear edges. It gradually expands and becomes semi-annular, annular or cloud-like. The scales are attached to the top, the inner edges are raised, and the itchiness is self-conscious, gradually changing from red to purplish red, brown, or skin color. If ringworm is not treated in a timely manner, the damage spreads and expands to the surrounding area, and the center of the lesion gradually heals itself and progresses to the surrounding area, with the edges of the erythema being more obviously inflamed, and there may be active papules, blisters, scales, and even vesicles and oozing on top. The lesions leave temporary hyperpigmentation after they heal. Tinea cruris also has a chronic course and over time, the lesions can become mossy due to scratching and irritation.
How to prevent ringworm?
1, to eliminate the source of infection: clean yourself, do not have inappropriate sexual relations with other people. Do not use other people’s underwear, underwear and common toiletries.
2. Actively cure tinea cruris, tinea nail, tinea corporis and pruritic skin diseases of the perineum. Avoid epidermal damage to prevent infection to the pubic area by hand or bathing products. The bath towel should be separated from the foot towel.
3. Pay attention to wearing loose, ventilated, sweat-absorbing underwear, changing and ironing frequently and keeping the vulva clean, dry and ventilated, and washing and tanning clothes frequently.
4. Avoid sitting for a long time, or sit with your legs apart to reduce sweating and promote the dispersion of damp heat in the femoral area, and sprinkle talcum powder locally to make the area dry.
How to treat ringworm?
Principles.
1. Choose the agent according to the skin rash type: the papule and blister type should use the lotion; the erythema, desquamation and mild hypertrophy type should use the cream.
2. Use ringworm-killing, antibacterial, and anti-itching agents.
3.Depending on the size of the lesion, use topical or oral.
4.For those who have tinea nail, tinea pedis or tinea corporis in combination, treat them together until they are cured.
5. Use medication only after a clear diagnosis is made. Do not use corticosteroid drugs before diagnosis.
Generally, topical medications are the mainstay. You can apply compound salicylic acid solution, compound tincture of hibiscus tincture, compound benzoic acid rub, compound benzoic acid ointment, bifenbendazole solution or cream, cyproheptadine (ringli) ointment, clotrimazole cream, 2% miconazole cream, 2% ketoconazole cream or 1% econazole cream, terbinafine rub or cream, etc. once or twice a day for 2 to 4 weeks. Depending on the situation some can be treated for 2-3 courses. However, the above-mentioned drugs have a lot of side effects in the treatment of ringworm, and because the skin of the femur is tender, topical application of ringworm drugs with irritating properties should be avoided. For large areas and many parts of the body, it can be treated with internal medications such as itraconazole and terbinafine, etc. The usage requires a doctor to decide the amount of medication and the time to take it according to your situation. Each place has its own customary medication or experience, and it is convenient for the patient to take the medication locally to reduce the burden. Some drugs will cause peeling after application, which is normal, by the peeling effect, so that the bacteria and skin from the body off, generally to repeatedly off 2-4 times on the cure. To eradicate it is necessary to prevent reinfection, local keep dry, used underwear to disinfect treatment or fee discard.
