Tinea capitis is a common and frequent disease that occurs in people with moist, sweaty hands and feet; it is a superficial fungal infection that occurs in the skin between the palms, plantars and fingers and toes. It is a common dermatological disease that is often treated by the fungus Trichophyton rubrum, Trichophyton rubrum and Trichophyton flocculare. Tinea capitis is a common skin disease and is often treated clinically. Tinea capitis is called “goosefoot” when it is severe, and tinea pedis is called “foot fungus” or “athlete’s foot” or “foot dampness”. The symptoms are blisters on the toes, peeling skin or white, wet skin, or vesicles or thickened, rough, cracked skin that can spread to the soles of the feet and the edges of the back of the feet. It is intensely itchy and must be scratched until it is broken. Tinea pedis is more common than tinea cruris and can be clinically classified into several types including keratosis, blister, papulosquamous, interscalene, and tinea corporis, or can be mixed. The goal of treatment for tinea pedis is to remove the causative organisms, quickly relieve symptoms, and prevent recurrence. There are three main methods of treatment, namely topical treatment, systemic treatment, and a combination of the two. Different treatment methods should be selected based on factors such as the type of causative organism, clinical typing, and the patient’s underlying condition. Currently, antifungal drugs commonly used in the treatment of tinea pedis include: azoles, arylamides, thiophanes, morinines, and vincristine. Among them, arylamines and azoles are most widely used clinically. Topical treatment: Topical treatment has the advantages of rapid onset of action, high safety and low cost, and is usually widely used. The dosage forms include creams, solutions, gels, sprays and powders, etc. The appropriate dosage form should be selected according to the characteristics of the lesion. Commonly used azoles include miconazole, econazole, clotrimazole, ketoconazole and bifenoconazole, etc. The usage is one or two times a day for at least 4 weeks, with a fungal cure rate of 60% to 91%; acrylamides include terbicaprepitant, butyroprepitant. In addition, some keratin exfoliators also have some antifungal effects, such as glacial acetic acid, salicylic acid, and relecitrin. Although topical medications are commonly used as a treatment method, there are certain limitations, such as poor patient compliance, uneven application of medications that can easily cause skin lesions to be missed, and physical and psychological discomfort to patients; poor penetration of medications for scaly keratosis pedis. Therefore, topical medication alone is only suitable for patients with incipient or limited lesions of tinea pedis. Systemic treatment: Oral antifungal medications are effective in treating tinea pedis and have the advantages of a short course of treatment, ease of administration, no missed lesions, high patient compliance, and low recurrence rate. It is suitable for those who have poor results of local treatment, recurrent attacks, scaly keratinized type, large area of involvement, with certain systemic diseases and those who do not want to receive local treatment. Studies have shown that oral terbinafine 250mg/d for 1-2 weeks for tinea pedis has a fungal cure rate of 89.3% at 12 weeks, with an annual recurrence rate of only about 10% at 3 years of follow-up; the efficacy and safety of oral terbinafine for 1 week is similar to that of topical clotrimazole cream for 4 weeks. Itraconazole 400 mg/d shock treatment for 1 week was also effective, with a fungal efficiency of 56%, but studies of long-term efficacy were lacking. There is less information on the treatment of tinea pedis with fluconazole. The safety of terbinafine and itraconazole has been confirmed by numerous clinical studies at home and abroad, but they should be used for certain special populations with reference to the instructions. Combination of topical and oral agents: Because of the limitations of both topical and systemic therapy, the combination of topical and oral antifungal agents is increasingly being promoted in clinical practice. Studies have shown that combination therapy regimens have shown advantages in shortening the course of treatment, reducing costs, improving compliance and efficacy, and reducing recurrence rates. It is especially suitable for those with recurrent attacks and poor compliance. When tinea pedis is combined with bacterial infection, antibacterial treatment should be administered first, local lesions should be treated according to the principles of eczema treatment, and antifungal treatment should be administered after the bacterial infection is controlled. Prevention: Tinea pedis can be cured, but it is prone to recurrence or reinfection. Good health education is essential to prevent tinea pedis, reduce recurrence, and reduce transmission. ① Pay attention to personal hygiene, such as using your own slippers and bath towels.
