As the temperature rises and summer is approaching, the warm and humid environment is conducive to fungal growth. In this hot and humid environment, fungi proliferate and spread. Tinea pedis is a recurring blistering, keratotic and flaky lesion that occurs on the toes, palm and plantar areas and is accompanied by itching. It is mostly caused by Trichophyton spp. (mostly Trichophyton rubrum) and S. epidermidis. The incidence is higher in tropical and subtropical areas, higher in urban than rural areas, and up to 80% or more in occupations such as sanitation workers and military personnel who wear impermeable rubber shoes for long periods of time. In addition, the high incidence of tinea pedis is also related to the anatomical characteristics of the foot, where the abundance of sweat glands and the absence of sebaceous glands make the skin surface alkaline and conducive to fungal growth, while the thick stratum corneum on the bottom of the foot provides rich nutrition for fungal growth. In addition, some fungi can form special structures of joint spores within the dermis, and these spores can survive for a long time in the natural environment and have the ability to cause disease. Many people believe that tinea pedis cannot be treated, saying that it is a channel for detoxification; in fact, it is not, and many patients are seen clinically to have delayed treatment, leading to the occurrence of ringworm, tinea, infection, and gray nails, as well as infecting their families. Summer is the high season for tinea pedis, so it is important to take the time to cure it. Treatment: 1. Topical medication (superficial fungal disease) Imidazoles: Clotrimazole, Ketoconazole, Econazole, Bifenoconazole Propylamines: naftifine, boutinafine, terbinafine. Traditional antifungals: salicylic acid, benzoic acid, sulfur, iodine. Others: mycoplasma, ciclopirox 2. Systemic antifungal therapy (ringworm of the head, nail fungus, intractable tinea corporis, ringworm of the femur, and ringworm of the hands and feet and deep fungal disease) Ashwagandha: the drug of choice for ringworm of the head, ringworm of the femur, ringworm of the feet, and ringworm of the body. Itraconazole, terbinafine: broad spectrum, high efficacy, low toxic side effects, suitable for all kinds of skin fungal infections Fluconazole: skin mucosal Candida infections, pay attention to liver function. Prevention: Prevention of tinea pedis is crucial. Eliminating the fungal breeding environment, especially in the warm and humid season, will effectively prevent tinea pedis. 1. Keep your feet clean and dry: Wash your feet with soap when bathing and then dry them. Wear cotton or cotton-wool blended socks that are easy to absorb sweat during the day at work, and try to wear shoes with good ventilation and air permeability. Wash your feet regularly, wash your shoes and socks regularly, and keep your shoes ventilated and dry. Those with sweaty feet can use talcum powder or other powders to keep their feet dry. After tinea pedis has been cured, use antifungal dispersions in the feet and shoes frequently to prevent recurrence. 2. Treatment of the source of infection: During the period of illness, cotton socks should be boiled in hot water for 15 minutes after wearing before washing, insoles should be replaced with new ones, do not scratch the affected skin, and make sure to wash your hands after contact to avoid infecting your hands or other parts of your body. 3.Prevent cross-infection: do not share shoes and socks, slippers, bath towels, basins and footbaths with others; keep the bathroom floor clean and do not use public slippers.
