Background:
@EN Superficial fungal infections are common diseases and the prevalence of superficial fungal diseases are not static but change under the influence of various forces such as climate, migration of peoples and development in prophylaxis and
therapy.
@ES Objective:
@EN To investigate the present status of superficial dermatophytoses and some changes on the frrequency of the diseases, sex distributions and varieties of the casuative organisms.
@ES Methods:
@EN The clinical and mycological aspects of superficial fungal diseases of 3,222 patients from July 1989 to June 1992 were analyzed.
@ES Results:
@EN 1) The incidence of superficial fungal diseases was 25.4% of total out-patients. 2) The superficial fungal diseases showed a higt incidence in the third(26.4%) and the fourth decade(24.3%). 3) The ratio of male to female was
2.11:1(2,188:1,034). 4)
The monthly prevalence of superficial fungal diseases was high in July(17.8%), August(15.2%) and June(11.&%). 5) The incidence of superficial fungal diseases in order of frequency were tinea pedis(28.1%), tinea cruris(19.5%),
onychomycosis(15.6%),
tinea
corporis (11.5%), tinea manus(7.8%), tinea versicolar (7.8%), candidiasis(7.4%) and tinea capitis(2.3%), 6) Coexisting fungal infections were found in 644 patients(19.9%) and the case of tinea pedis with onychomycosis ws the most common. 7) The
positive
rate of KOH scraping was 54.0% and the positive rate of culture on ordinary Sabouraud's dextrose agar media was 42.7%. 8) Trichophyton rubrum was the most common causative organtism of superficial dermatophytes(38.4%), and other in decreasing
frequency
were Candida albicans(36.9%), Trichophyton mentagrophytes(23.6%) Microsporum canis(0.7%), Trichophyton ferrugineum(0.3%) and Epidermophyton floccosum(0.1%).
@ES Conclusion:
@EN These results are not significantly different from those of previous studies. But the incidence rate of the superficial fungal diseases(25.4%) were higher than previous studies and showed a high incidence in young male patinets and tin the
summer.
The positive rate of KOH scratping(54.0%) was lower than previous studies. The most common causative organism was Trichophyton rubrum(38.4%). (Kor J Dermatol 1993;31(4) 559~566)
