ABSTRACT:Background: Psoriasis is a worldwide disease and varies in its clinical profile and epidemiology in different regions of the world. The disease is common and few epidemiological data are available in our country. Objective: The purpose of this study was to evaluate the epidemiologic and clinical features of Psoriasis in Lumbini Medical College. Methods: A retrospective investigation of a total of 240 patients visiting Out Patient Department (OPD) of Dermatology and Venereology of Lumbini Medical College with Psoriasis was done. The parameters included were age at onset of disease, age at first treatment, current age, sex, type of disease and distribution of lesions. Data and statistical analysis was done with SPSS 17.0. Results: The mean age of patients at onset of disease was 26.4 (SD = 14.3) years. M:F ratio was 1.16. Psoriasis vulgaris (PV) was the most common variety of the disease. Extensor surface of the body was most commonly involved. Conclusion: Psoriasis is a common dermatological disease accounting 2.9% of all dermatology patients in our center. PV is the most common clinical subtype. The disease is more frequent in the third decade of life and has a male predominance in our region. Treatment compliance has been found to be poor.

Introduction: Skin diseases are common in children; however they differ depending in age, region, socioeconomic status and climate. Many studies have been done to study pattern of dermatological disease in pediatric age group but only few studies have been done in its seasonal variation. So we decided to study seasonal variation of pediatric dermatoses.   Methods: This was retrospective study done from hospital record of Lumbini Medical College Teaching Hospital (LMCTH). All children 14 years and below attending the Dermatology out-patient clinic with skin diseases between the period of March 2015 to February 2016 were included. Demographic, clinical and laboratory details were recorded. Data were collected and categorized according to four seasons. Microsoft Excel was used for data entry while all analysis, both descriptive and inferential, was done using SPSS version 22.   Results: There were a total of 987 children visiting Dermatology clinic during the study period. Of those, 520 (52.7%) were male and the remaining 467 (47.3%)  were female with M:F ratio of 1.1:1. Most of the disorders were seen between 10-14 years of age. Majority of visits was in summer (n=403, 40.8%) followed by spring, autumn and winter. Most common dermatosis seen among children during summer was fungal infection (n=91, 9.2%) and during winter was eczema (n=49, 5%).   Conclusion: In the present setting there is seasonal variation of dermatological diseases in pediatric age group.
