Tinea pedis (ringworm), commonly known as athlete’s foot, is a superficial fungal infection that occurs in the skin between the palms, metatarsals, and toes of the feet. The prevalence of tinea pedis is high, especially in the south of the country, where it is more than 80%. The phenomenon of cross-infection of tinea pedis in the family cannot be ignored. Surveys have shown that 46.1% of patients have family members who are infected at the same time, and strain identification reveals that 85.4% of patients have the same pathogenic fungus as their family members. This is strong evidence that the family has become an important site of fungal transmission. The widespread spread of fungi within the family is mainly due to the patient’s lack of attention to the disease, failure to seek and adhere to proper treatment in a timely manner, and poor hygiene practices within the family. When a family member develops tinea pedis and it is not treated in a timely manner, the diseased skin acts as a fungal reservoir, constantly spreading pathogenic fungi outward and infecting family members in close contact through shared bath tubs, towels, slippers, and other items. If untreated, tinea pedis infections not only infect family members, but also cause fungal infections in other parts of the body, such as tinea corporis, tinea cruris, tinea nail (gray nail), mycosis fungoides, and genitourinary infections. If treatment is not timely or appropriate, it can also lead to bacterial infections such as lymphangitis, cellulitis, and calf dermatitis, or in severe cases, sepsis. Can tinea pedis be cured or not? The answer is yes. The reason for the recurrence of tinea pedis is unreasonable and unregulated diagnosis and treatment. Therefore, it is important to standardize the treatment of tinea pedis in order to achieve a true cure. Tinea pedis treatment is divided into topical treatment and oral treatment.1. Topical medications are commonly used. There are a wide variety of topical antifungal medications, including azoles, acrylamides, morpholines and some keratin exfoliants, and the appropriate dosage form should be chosen according to the characteristics of the lesions. However, there are certain limitations, such as poor patient compliance: the literature shows that 82.5% of patients with tinea pedis persist with topical medication for less than 2 weeks. The effectiveness of topical treatment alone is poor and the recurrence rate is high (50% to 80%). 2. Oral medication is suitable for patients with poor topical treatment, recurrent attacks, and large areas of involvement. However, the long course of oral medication alone has a great impact on liver and kidney function, and patients often fail treatment because they cannot tolerate it. The Department of Dermatology at Chenzhou Third Hospital has developed the “1+1” combination of oral and topical treatment based on the poor efficacy of traditional treatment methods after years of effort. It is very effective in treating tinea pedis, with a cure rate of 98% and an overall efficiency of 100%.
