ABSTRACT

Background: clinical presentations of tinea pedis are: interdigital –most frequent–, moccasin, inflammatory and bullous. It’s infrequent on children, with an estimated prevalence of 3.4%, however this frequency may change with sports specially in swimmers.
Objectives: to determine the frequency and causal agents of tinea pedis in children practicing swimming.
Materials and methods: descriptive, transversal and prospective study performed on a sports center in Mexico City with children from four to 13 years of age who practice swimming at least two hours per week. An accurate physical exam was performed looking for tinea pedis and swab sample was taken from the 4th and 5th interdigital space of right foot; culture on dextrose Sabouraud agar was performed.
Results: We included 24 of 83 swimming children, 19 male and five female with a mean age of 9.3 years. We found seven patients with clinical intertrigo, of which five corresponded to Candida intertrigo (four C. glabrata and one C. albicans). Candida spp, was isolated on five of 17 patients who had no clinical lesions, it corresponds to carriers. Clinical onychomycosis was suspected in 14 of 83 patients, seven samples were discarded for lack of adequacy. Microscopic examination with koh was performed on the seven remaining samples, confirming a case of superficial white onychomycosis.
Conclusions: this study shows a low prevalence of tinea pedis in this group of children who practice swimming. We found an 20.83% of Candida intertrigo and a 8.33% of intertrigo related with moist and maceration. We observed a 16.87% of clinical nail lesions suggestive of onychomycosis and we were able to confirm one case of superficial white onychomycosis.
