Background: Treatment of early-stage mycosis fungoides (MF) consists of topical steroids, phototherapy (UVB), photochemotherapy (psoralen plus UVA [PUVA]), topical nitrogen mustard, or total skin electronbeam irradiation. It has been reported that the same effective UVB dose is safer than PUVA regarding carcinogenicity and produces fewer side effects. Narrowband UVB (311 nm) results in less irr...

To elucidate the molecular action of 8-methoxypsoralen plus UVA (PUVA), a standard dermatological therapy, we used K5.hTGF-beta1 transgenic mice exhibiting a skin phenotype and cytokine abnormalities with strong similarities to human psoriasis. We observed that impaired function of CD4+CD25+ regulatory T cells (Tregs) and increased cytokine levels of the IL-23/Th17 pathway were responsible for ...

introduction: palmoplantar psoriasis could hardly be differentiated from chronic tylotic eczema both clinically and histologically. the most commonly used therapeutic options for palmoplantar psoriasis are long-term therapy with topical corticosteroids and local puva. frequently, it is a recalcitrant disease. we investigated the efficacy  and tolerability of the combination of topical calcipotr...

Cutaneous T-cell lymphoma (CTCL) constitutes a malignant proliferative disease involving mostly CD4(+) T cells arising in the skin. Because of the lack of curative treatment options, interferons (IFN) have been introduced into the therapy of CTCL. Although effective even in advanced disease, response rates were about 50% and the duration of response was short. To improve the results of interfer...

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...

Treatment of vitiligo can sometimes be difficult and disappointing. PUVA treatments give fairly good results. However, acral regions like the hands or feet or areas over bony prominences like the elbow, are resistant to PUVA. Blister-induced epidermal grafts have been used to repigment vitiligo skin. This study was carried out on patients with vitiligo areas unresponsive to either PUVA treatmen...

Case Report A 53-year-old male anaesthetist with a widespread, histologically proven psoriasis vulgaris was treated with oral photochemotherapy (PUVA) after failure of multiple intensive topical treatments and poor response to UVA-UVB phototherapy. PUVA was begun according to our standard protocol: 2 h after oral administration of 5-MOP 100 mg (Geralen , 1.2 mg/kg body weight), the patient was ...
