A Statistical Study of Dermatoses in Wonju (2005~2009) / 대한피부과학회지

BACKGROUND: While the incidence of skin diseases in our university hospital may not indicate their true incidence in the population, it nonetheless represents the only available source of information. Recently, the composition of the Wonju population has changed rapidly in that the population of old people is increasing and urbanization is accelerating. Thus, statistical study of the latest data is necessary. OBJECTIVE: To study the prevalence of common dermatoses and compare this with previous reports. METHODS: We reviewed 27,718 new outpatients who visited the department of dermatology at Wonju Christian Hospital from 2005 to 2009, and statistically analyzed the findings. RESULTS: The study results are summarized as follows: Of the 27,718 outpatients, the total number of male patients was 14,190 (51.2%), and the numbers of female patients was 13,528 (48.8%). The most frequent age groups were the fifth decade (15.9%), sixth decade (13.9%), seventh decade (13.2%), and fourth decade (12.5). The 20 most common dermatoses were dermatophytosis, urticaria, atopic dermatitis, allergic contact dermatitis, other eczema, verruca, alopecia, herpes zoster, pruritus, psoriasis, drug eruption, vitiligo, acne, seborrheic dermatitis, folliculitis, benign epidermal tumors, nevocellular nevus, irritant contact dermatitis, bacterial diseases, and rosacea. The dermatoses which revealed a decreasing tendency to be treated by medicine included dermatophytosis, atopic dermatitis, other eczema, pruritus, psoriasis, drug eruption, vitiligo, acne, and irritant contact dermatitis. An increasing tendency was noted in urticaria, allergic contact dermatitis, verruca, alopecia, herpes zoster, seborrheic dermatitis, folliculitis, benign epidermal tumor and nevocellular nevus. Diseases with high seasonal distribution in summer were dermatophytosis, herpes zoster, vitiligo, folliculitis, irritant contact dermatitis and bacterial infections. However, atopic dermatitis, pruritus, and psoriasis showed high incidence in the winter period. Verruca, acne and nevocellular nevus had a peak incidence in both summer and winter. CONCLUSION: The distinct characteristic of skin diseases of the Gangwon province was a high incidence of pruritus and seborrheic dermatitis which represent the senile diseases.

The Epidemiological Characteristics of a Shigellosis Outbreak (1998) in Wonju City, Kangwon-Do / 한국역학회지

From September 8-28 1998, 55 cases of shigellosis, characterized by watery diarrhea, high fever, abdominal cramps and headache were reported at K elementary school in Wonju City. The isolated serotype was Shigella sonnei (group D). We collected bacteriologic specimens from high-risk populations, disinfected epidemic areas, and monitored all the medical facilities in Wonju City. Through these efforts, we found 168 cases of shigellosis, and of these, 117 were culture-confirmed and 51 were diagnosed by symptoms. The incidence rate per 10,000 population in Wonju City was 1.00 in males and 1.19 in females. The secondary attack rate was 13.6%. The mode of transmission at K elementary school was most often caused by the common epidemic source of single exposure. The source of infection was believed to be the foods distributed on September 7. However, epidemiologic evidence suggested that the sources of infection were scattered over many places within the city. The reasons included: i) shigellosis is an endemic disease in Korea; ii) there were shigellosis-like patients at J primary school in Wonju City in late August; and iii) there was a shigellosis outbreak at Chongil Myun, Hoeng Seong Gun, which was located near Wonju City, in early August.

A Statistical Study of Dermatoses in Wonju Area During the Recent 5 Years ( 1980 ~ 1984 ) / 대한피부과학회지

In this report, 20,536 new outpatients who have visited the Department of Dermatology of Wonju Christian Hospital from Jan. 1st, 1980 to Dec. 31st, 1984 were analized. The results suggest that the age, sex, monthly and yearly distribution patterns of dermatoses in Wonju area are similar to those of other areas in Korea except that infective dermtoses(40.3%), especially scabies(9.8%) and herpes zoster(1.6%) are more common.
