Tinea pedis

　　The pathogenic bacteria of tinea pedis are mainly the Trichophyton genus and the Epidermophyton genus. Common species include Trichophyton rubrum, Trichophyton须毛癣菌 and Trichophyton mentagrophytes. Among them, Trichophyton rubrum has become the main pathogen of tinea pedis in China due to its strong resistance and difficulty in control. Tinea pedis is transmitted by contact. It is easy to be infected with the disease by taking a bath in a public bathhouse, wearing public slippers, wearing the shoes, socks, and gloves of patients, using public towels, and so on.

　　In addition to its clinical manifestations, tinea pedis can also cause other diseases. This disease can cause erysipelas, acute lymphangitis, and acute cellulitis, so it should be highly regarded by clinical doctors and patients.

　　Tinea pedis is classified into the following four types according to clinical manifestations:

　　1. Macerated type

　　The interdigital skin of the feet (fingers) is often white, eroded, and macerated, with clear edges. After removing the macerated epidermis, moist fresh new skin remains.

　　2, Blisters type

　　Blisters are common on the sole or palm of the foot, and even several blisters merge into larger blisters. The boundaries of the blisters are clear, but the skin is not red.

　　3, Scaly type

　　Scaly type is mainly characterized by desquamation, with a few cases of water blisters. The blisters dry and peel off, with clear boundaries and slight inflammation.

　　4, Thickening type

　　Scaly type is common with thickening of the palmoplantar skin. In summer, blisters peel off, and the skin cracks in winter.

　　When preventing tinea manuum and pedis, attention should be paid to the following aspects:

　　In daily life, it is necessary to pay attention to personal hygiene and not use public slippers, foot basins, towels, etc.

　　Excessive sweating and injury of the hands and feet are often one of the most common triggers for tinea pedis or tinea manuum. In daily life, it is necessary to reduce the adverse stimulation of chemical, physical, and biological substances on the skin of the hands and feet.

　　After washing feet or taking a bath at night, dry the moisture between the toes, and try to keep the toes dry.

　　Public places such as bathrooms and swimming pools are the main places for the transmission of tinea pedis, and strict disinfection management systems should be implemented.

　　When diagnosing tinea manuum and pedis, in addition to relying on its clinical manifestations, it is also necessary to rely on auxiliary examinations. The disease can be diagnosed clearly based on clinical manifestations and combined with fungal microscopy or culture. In treatment and prevention, patients need to pay attention to maintaining personal hygiene in their daily lives, and not using public slippers, foot basins, towels, etc.

　　Patients with tinea manuum and pedis should eat antibacterial and anti-inflammatory foods such as aloe vera, lemon, and silver ear, and should eat foods that enhance the body's immune system. In addition, patients need to pay attention to avoiding spicy foods such as white wine, chili, and Sichuan pepper. Avoid eating foods rich in fats, such as lard, fatty meat, and mutton fat.

　　When treating tinea manuum and pedis, imidazole or ketoconazole ointment can be applied to the affected area 2-3 times a day. For patients with skin ulcers, antifungal root extract or 2% gentian violet liquid can be applied externally. Since fungal infection is deep in the skin, external medication is difficult to cure. To completely cure tinea manuum and pedis, patients should go to the dermatology department of the hospital and use oral antifungal drugs under the guidance of a doctor, such as itraconazole, fluconazole, etc.
