Prevalence of tinea capitis and tinea pedis in Barcelona schoolchildren.
BACKGROUND
Although dermatophytoses can appear at any age, some types are particularly prevalent in children. There are no prior data on the prevalence of tinea capitis and tinea pedis in Barcelona, Spain. To identify the prevalence of tinea in school children in the area with the highest immigrant population in this city, a cross-sectional study was performed. A second objective was to identify the etiologic agent to study the possibility of the introduction of foreign dermatophyte species and to evaluate the possibility of encountering healthy hosts.


METHODS
From October 2002 until June 2003, we evaluated 1305 schoolchildren, ages 3-15 years, belonging to 21 schools located in the inner city of Barcelona to determine the prevalence of tinea capitis and pedis in school children. Cultures of scalp and feet were done in each child.


RESULTS
36(2.8%) children had tinea pedis and 3 (0.23%) had tinea capitis. One child had tinea capitis and tinea pedis, caused by different species (t. capitis caused by Trichophyton mentagrophytes and tinea pedis caused by Trichophyton rubrum). Of the 39 positive cases for dermatophytes, the etiologic agent in 18 (46.1%) was T. mentagrophytes, 17 (43.5%) T. rubrum, 2 (5.5%) Epidermophyton floccosum and 2 (5.5%) Trichophyton tonsurans. Of these 39 cases of tinea, 15 (38.5%) were Spanish natives and 22 (56.4%) were immigrants.


CONCLUSIONS
The prevalence of tinea capitis was lower that we had expected, and it was noted that there was a greater prevalence of tinea pedis among schoolchildren 13-15 years of age (64.10%), the great majority of them male. The number of cases of tinea was significantly greater in immigrants.
