title: Screening examination and treatment of Trichophyton tonsurans infection in judo athletes affiliated with the University Judo Federation of Tokyo.
abstract: In Japan, Trichophyton tonsurans infection has become an increasing problem among combat sports participants. We investigated the prevalence of T. tonsurans infection in athletes affiliated to judo clubs in the 21 First Division universities that were registered with the University Judo Federation of Tokyo in 2008. Study procedures performed by the subjects included (i) completion of a questionnaire concerning lifestyle, risk factors for tinea corporis and medical history; (ii) scrubbing the scalp with a circular hairbrush to obtain samples for fungal culture; (iii) anti-fungal treatment as recommended by a dermatologist, based on the number of fungal colonies isolated from the hairbrush; and (iv) repeat testing using the hairbrush method 3 months after treatment recommendations were received. Of 902 study subjects, 102 (11.3%) yielded positive hairbrush culture results. Of these, 14 individuals (13.7%) had tinea corporis; the remainder were asymptomatic. Conversion to negative fungal culture was observed in 85 of 96 culture-positive individuals who performed the second hairbrush culture test following treatment. Control of T. tonsurans infection among judo athletes could be achieved by educating athletes, trainers and coaches in judo clubs concerning detection, prevention, and treatment of T. tonsurans infection.
