Psoriasis is characterized by alterations in both the epidermis and dermis of the skin. Epidermal keratinocytes display marked proliferative activation and differentiate along an "alternate" or "regenerative" pathway, while the dermis becomes infiltrated with leukocytes, particularly interleukin 2 (IL-2) receptor-bearing "activated" T cells. Psoralens, administered by the oral route, have thera...

OBJECTIVE To perform a cost-effectiveness analysis, by using a decision tree model, comparing methotrexate with PUVA therapy for moderate to severe chronic plaque psoriasis in the sanitary area of Badajoz (south-western Spain) over a one-year period. MATERIAL AND METHODS The following variables and data sources were included: efficacy (a 50 % reduction in the PASI) and safety (adverse reactio...

Although extensive research has been done to improve the treatment of vitiligo, an universal effective treatment for vitiligo is not yet available [1]. PUVA therapy has demonstrated to have immunomodulatory effects, mainly in the T lymphocyte compartment but has several adverse effects, such as skin cancer risk [2,3]. The optimization of PUVA therapy is a relevant clinical objective in the mana...

Background: Vitiligo is a relatively common acquired depigmentary disorder affecting approximately 1% of general population. PUVA therapy is the most effective modality and commonly used as the primary treatment of generalized Vitiligo. Objective: To evaluate the synergistic effect of topical Calcipotriol and oral methoxalene plus PUVA in treatment of generalized Vitiligo. Patients and Me...

Background. Bullous pemphigoid is an autoimmune subepidermal blistering skin disease in which autoantibodies are directed against components of the basement membrane. The disease primarily affects the elderly people and in most of the patients inducing factors cannot be identified. Herein, we report a case of BP that occurred in a patient who was receiving PUVA therapy for the treatment of myco...

BACKGROUND Oral 8-methoxypsoralen-UV-A (PUVA) and Narrowband UV-B (NB-UVB or UVB TL-01) are well established treatments for chronic plaque psoriasis but there is limited evidence regarding their respective efficacy. OBJECTIVES To prepare for evidence-based recommendations concerning the practical use of oral 8-methoxypsoralen-UV-A and Narrowband UV-B in psoriasis, a systematic review to asses...

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...

Vitiligo is a dreaded disease in India due to its social and cultural consequences. PUVA and PUVAsol are the main treatment modalities for vitiligo vulgaris. To the best of our knowledge, this is the first case of accidental PUVA burns eventuating in prurigo nodularis lesions to be reported in a female patient who was undergoing home PUVA therapy. The itch is so prominent and disabling that the...

Background: Topical corticosteroids and oral psoralen plus ultraviolet A radiation (PUVA therapy) are two common treatment methods for vitiligo. The aim of this study was to compare the efficacy, complications and patterns of repigmentation of these two methods. Methods: This prospective randomized clinical trial was conducted from July 2007 to October 2008. Patients with disseminated vitiligo ...
