Statistical Analysis of Herpes Zoster in Chuncheon and the Northern Kangwon province ( 1994-1996 ) / 대한피부과학회지

ABSTRACT

BACKGROUND: Herpes zoster is a relatively common dermatological disease and there have been several reports on the epidemiological study of herpes zoster in Korea. However there has not been any report on the epidemiology of herpes zoster in Chuncheon and the Northern Kangwon Province. OBJECTIVE: The purpose of this study was to elucidate the epidemiological characteristics of herpes zoster in Chuncheon and the Northern Kangwon Province. METHODS: The authors evaluated about 461 cases of herpes zoster with retrospective methods with regard to annual, monthly and seasonal incidences, age, sex ratio, associated conditions, anatomical distribution and complications at the department of dermatology in Chuncheon Sacred Heart Hospital, Hallym University during a 3-Year-Period from Jan. 1994 to Dec. 1996. RESULTS: The annual incidence of herpes zoster in new patients from our dermatology clinic ranged from 4.3% to 4.8%(mean 4.5%), and the ratio of male to female was 11.12. The peak incidence of monthly and seasonal analysis was in December and in the Fall. The majority of cases occurred most frequently over the 6th decade. The most common anatomical distribution of herpes zoster inpatients(211 cases) was thoracic dermatome(52.9%), followed by the ophthalmic branch of the trigeminal nerve(17.0%), cervical(13.6%), lumbar(6.3%), sacral(4.4%), maxillary branch of the trigeminal nerve(3.9%) and two different dermatomes (2.8%). Associated conditions of herpes zoster inpatients(211 cases) were observed in 108 patients (51.2%); hypertension(31.9%), gastritis(15.1%), diabetes mellitus(11.8%), hepatitis(9.2%), malignancy (8.4%), tuberculosis(4.2%), and so on. The complications including postherpetic neuralgia were observed in 58 patients(27.5%) and were common after the age of 50 years. The rnost common complication of herpes zoster inpatients(211 cases) was postherpetic neuralgia(14.7%), followed by ophthalmologic complications(8.1%), secondary bacterial infections(1.4%), neurogenic bladder(1.4%), otologic complications(0.9%), and so on. CONCLUSION: Most of the other results of our study were similar in comparison with reports from other regions in Korea, except for a higher annual incidence and significant differences in the monthly incidence. These differences reflected the regional characteristics of medical service delivery systems in Chuncheon and the Northern Kangwon Province.
