A study of epidemiology of pityriasis rosea and therapeutic effect of narrow band ultra violet B phototheraphy on its course

Aims and Objectives: The aims and objectives of the study was to know epidemiological profile- incidence, age, sex, seasonal variation and morphological variant and also to study the efficacy and safety of NBUVB in treatment for Pityriasis rosea. Material and methods: A randomized control clinical trial was conducted in department of dermatology, venereology & leprosy, MDM Hospital, Jodhpur among 60 patients (30 for NBUVB and 30 as control) for one year. results and conclusion: After this study and observations, we would like to conclude that a fixed dose regimen of 250mj/cm2 of NBUVB phototherapy for a four week course in treatment of pityriasis rosea helps in the reduction of duration of disease and morphological parameters of pityriasis rosea in terms of erythema, scaling and induration as compared to Control. There was also significant improvement in the symptoms of pityriasis rosea like pruritus to a significant level in NBUVB as compared to control. However a larger study should be performed to confirm these findings
