UVB is widely used to treat psoriasis. Conventional broadband UVB lamps are less effective than narrowband UVB lamps, which have an emission peak at 311 nm. The long-term safety of narrowband UVB phototherapy is uncertain. "Selective" broadband UVB lamps, which have little emission <290 nm, are also available, but have not been adequately compared to narrowband UVB lamps. We performed a randomi...

Background. Many studies, on light-skinned patients, suggested narrowband-UVB to be effective and safe for the treatment of early stage cutaneous T-cell lymphoma. Objectives. To evaluate the efficacy and side effects of narrowband-UVB in treatment of early stage cutaneous T-cell lymphoma in patients with skin phototypes III, IV, and V. Methods. A total of 27 patients with the diagnosis of early...

BACKGROUND Hand eczema is a chronic skin disorder characterized by a poor response to conventional therapies. Although local PUVA has been proven to be effective in the treatment of chronic hand eczema, little is known about the efficacy and safety of local narrowband UVB (TL-01) for this condition. The aim of our study was to compare the efficacy and safety of local narrowband UVB phototherapy...

Topical pimecrolimus and narrowband ultraviolet B (UVB) are both known to be effective in treating atopic dermatitis. We compared the clinical efficacy of monotherapy with either twice daily topical 1% pimecrolimus cream or twice weekly narrowband UVB, and combination therapy in 26 children and adolescents with moderate to severe atopic dermatitis in a half-side manner for 6 weeks. Twenty-four ...

Phototherapy with ultraviolet (UV) radiation of wavelengths between 280 and 320 nm (UVB) is a safe and effective treatment for a variety of diseases. In addition to standard broadband UVB (bUVB), narrowband phototherapy with fluorescent bulbs emitting near monochromatic UV around 311 nm (nUVB) has become an important treatment for diseases such as psoriasis, atopic dermatitis and vitiligo. In a...

Phototherapy of skin diseases such as psoriasis is an effective and safe treatment modality. However, increasing the risk of skin cancer by phototherapy is a serious concern. An increased skin cancer risk occurs after prolonged photochemotherapy (PUVA). In contrast, the role of broadband UVB or narrowband UVB therapy in skin carcinogenesis of humans with psoriasis is less clear. Therefore, we i...

BACKGROUND Progressive macular hypomelanosis is a common dermatosis in various continents. Its cause is unknown and proposed treatments have had little effect. OBJECTIVES To determine epidemiological aspects of progressive macular hypomelanosis in patients referred to a phototherapy clinic between 1997 and 2008 and to evaluate therapeutic response to PUVA (psoralen + UVA) photochemotherapy or...

In addition to therapeutic options such as steroid ointment, immunosuppressive drug and ultraviolet phototherapy, recent reports have demonstrated the clinical efficacy of topical vitamin D3 for vitiligo vulgaris. However, there seems to be little clinical effect of vitamin D3 without UV exposure. In the present study, we evaluated the clinical difference of sun irradiation vs. narrowband UVB i...
