A Clinical and Mycological Study of Superficial Dermatophytoses / 대한피부과학회지

ABSTRACT

This study was made in order to investigate the present status of superficial dermatophytoses and some changes on the frequency of the diseases, sex distributions and varieties of the causative organisms. The survey was made by 1486 out-patients of dermatology clinic of National Medical Center from May to August in 1978. Following results are obtained 1. The incidence of superficial fungal infections including Tinea versicolor is 22. 2% and Tinea versicolor alone is 2. 8% among total l486 out-patients. 2. The ratio of male to female patients is 190140 and shows more prevalence in male. 3. The age group from 20 to 29 shows the highest incidence and 38. 3% of all patients with superficial fungal infection falls in this age group. 4. Tinea pedis reveals the commonest disease and others in decreasing frequency are Tinea corporis, Onychomycosis, Tinea manus, Tinea corporis, Candidiasis and Tinea capitis. 5. Coexisting fungal infection is found in 60 patients and is most prevalent in the age group from 40 to 49, related to the ratio of age specific coexisting cases to each age group patients. 6. Tinea pedis with Onychomycosis reveals the most prevalent coexisting superficial fungal infection and others in decreasing frequencies are Tinea pedis with Tinea manus, Tinea pedis with Tinea cruris, Tinea cruris witb Tinea corporis and so on. 7. Positive rate of KOH mount among 362 scrapings is 64. 7% and Tinea cruris shows the highest positive rate (86. O%.) and Tinea corporis the next (78. 6%). 8. 187 strains are isolated by Sabourauds dextrose agar, 140 from positive KOH scrapings and 47 from negative KOH scrapings. a. Trichophyton rubrum is the most common organism of superficial dermatophytosis (43 8%) b, Microsporum species reveal the most common organism of Tinea capitis (80%).
