  • Title: [Narrow spectrum (311 nm) phototherapy in treatment of psoriatic nail].
    Journal: Georgian Med News; 2009 Feb; (167):56-9. PubMed ID: 19276472.
    Abstract:
    Ultraviolet B phototherapy is a common treatment for psoriasis. It was determined that wavelengths between 305 and 315 nm have the best therapeutic effect. The aim of this study was the evaluation of efficacy of narrow spectrum (311 nm) phototherapy in the treatment of psoriatic onychia. The clinical presentation of psoriatic onychia is extremely diverse. 25 patients with psoriatic onychia (15 men and 10 women) from 10 to 65 years old were under observation. Duration of disease varied form 1 to 15 years. In the study were included patients with minimal, or without any skin manifestations of the diseases. In 7 cases the most common form of nails' psoriatic lesion - psoriatic onychia punctata was identified; in 10 cases - onycholysis, and in 8 cases - subungual hematoma. All patients 3-5 times a week underwent narrow spectrum (311 nm) mono - phototherapy (lamp - Philips TL-01 with maximal emission of 311 nm). Phototype of skin was evaluated according to B. Fitzpatrick. Clinical recovery was achieved in 16 psoriatic patients; notable improvement - in 5 and expected effect was not observed in 4 patients. Thus, our results allow to conclude, that narrow spectrum medium wave phototherapy (311 nm) is effective and safe in treatment of psoriatic onychia.
