Dermatophytosis is an infection produced by a dermatophytic fungus in the keratinized tissues-nails, hair, and stratum corneum of the skin. Although several types of the dermatophytes are geographically restricted and endemic only in particular parts of the world, these infections have been observed world-wide since the 1800s and many epidemiological studies have been reported until the present. The types and clinical severity of dermatophytosis are related to the host factors and virulence of the infecting organism. It is clear that such host factors as the host immunity, age, sex, race, habits, geographic location and genetic background. In addition to host factors and virulence of the infecting organism, increased traffic communications may have contributed to the degree of infection and the change in the infecting strains in the same location.
Many investigators have reported extensive epidemiological studies to dermatophytosis in other provinces of Korea, howerver, there isn´t up to now, even one report regarding dermatophytosis in this porvince of Kangwon.
In order to investigate the clinical and mycological trends of dermatophytoses in Kangwon province, during the past 2 years; June, 1985 to May, 1987, 812 dermatophytes who visited the Dermatology Clinic of Wonju Christian Hospital were studied using myological examination. The results are summarized as follows:
1. The seasonal distribution shows the highest during the summer months 44.2% with August demonstrated 15.4% while the winter months 16.3% with November reading 3.1%.
2. Among the 812 cases of dermatophytoses, tinea pedis (34.8%) was the most common clinical type, followed by tinea cruris, tinea unguium, tinea capitis, tinea corporis, tinea manus and tinea faciei.
3. The ratio of male to female patients was 1.3 : 1, and tinea cruris was more common in the male(11.6 times) while the tinea faciei was the more dominate in the female(1.7 times).
4. The incidence of dermatophytosis was 50% of total cases in 20-39 years age group, of which 30% were in the 20-29 year breaket. Tinea capitis and tinea faciei were the most common clinical type of dermatophytosis in the age group under the 10.
5. The occurance of concurrent infection was found in 12.1% of the cases demonstrated of which tinea pedis combined with tinea unguium beinging the most common.
6. The positive rate of KOH examination was 96.2% that is it showed the highest rate in each of the tinea cruris and the tinea unguium (98.3%) while the tinea capitis showed the lowest rate 85%. The positive rate of culture examination was 69.5% demonstrate the highest rate in tinea capitis (95.0%) and the lowest rate in tinea manus (47.8%).
7. Among the 564 strains isolated from 812 dermatophytoses, T. rubrum (65.3%) was the most common strain, followed by M. canis (16.3%), T. mentagrophytes (12.2%) T. interdigitale (3.0%), E. floccosum (2.3%), T. ferrugineum (0.5%) and M. gypseum (0.4%). Most of the isolated strains were observed during the summer but M. canis in T. capitis and T. faciei. Most E. floccosum was isolated in tinea cruris.
