Our Experience with Narrow-Band UVB for 15 Years: A Retrospective Study of 205 Patients.

Aim: Widely used in many indications in dermatology practice, narrow-band ultraviolet B is a kind of ultraviolet with a wavelength usually condensing at 312nm. Our aim in this study is to introduce our 15-year experience with narrow-band UVB on 205 patients. Materials and Methods: Gender, diagnosis, distribution of lesions, beginning dose, maximum dose, number of sessions, and cumulative dose of patients treated with narrow band UVB were retrospectively studied. Results: The mean age of patients was 37,2 years. 44,4% of the patients was males, 55,6% was females. 34,1% of the patients were diagnosed with psoriasis and 14,6% of the patients with mycosis fungoides. 73,7% of distribution of lesions was diffused, 28% was central, and 26% was peripheral. The mean number of sessions was 27,1 and the mean cumulative dose was 21070 mJ/cm2 in the first treatment. The mean starting dose was 125,4 mJ/cm2 and the mean maximum dose was 21070 mJ/cm². Conclusion: Differences between the means of the number of sessions, maximum doses, cumulative doses, and diseases were statistically significant. [ABSTRACT FROM AUTHOR]
