Photodynamic therapy of recalcitrant warts with 5-aminolevulinic acid: a retrospective analysis.
Sir, Photodynamic therapy (PDT) with topical application of 5aminolevulinic acid (ALA) has been successful in the treatment of super®cial non-melanoma skin tumours (1). When applied topically to the skin, ALA is absorbed into the epidermal cells and biosynthesized to the light-sensitive metabolite photoporphyrin IX (PpIX). When cells with accumulated PpIX are exposed to light of certain wavelen...
متن کاملEffect of Silver Nanoparticles on Improving the Efficacy of 5-Aminolevulinic Acid-Induced Photodynamic Therapy
Introduction: The most important limitation of 5-aminolevulinic acid (5-ALA)-induced photodynamic therapy (PDT) is the efficacy of the cells in converting 5-ALA to protoporphyrin IX. The present study aimed to investigate the effectiveness of silver nanoparticles (AgNPs) with the photosensitivity at the surface plasmon resonance wavelength on 5-ALA-mediated PDT. Material and Methods: First of a...
متن کاملPhotodynamic therapy for acne vulgaris with topical 5-aminolevulinic acid.
After obtaining informed consent, the patient was treated with topical 5-aminolevulinic acid photodynamic therapy (ALA-PDT). Twenty percent ALA (A 7793; Sigma, St Louis, Mo) in an oil-in-water emulsion (Yoshida, Tokyo, Japan) was applied to a 5 3 5-cm area of the right cheek for 4 hours with a light-shielded dressing. On Wood lamp examination, the affected lesion showed numerous dots of vivid r...
متن کاملImmunotherapy with diphenylcyclopropenone of recalcitrant warts: a retrospective analysis.
Sir, Recalcitrant warts remains a major therapeutic challenge for patients as well as for dermatologists, and an effective, painless, atraumatic treatment modality is needed world-wide. Topical immunotherapy has for years been used with some success in the treatment of resistant warts (1). Dinitrochlorobenzene (DNCB) was the ®rst contact sensitizer to be used but diphenylcyclopropenone (DCP) is...
متن کاملDerivatives of 5-Aminolevulinic Acid for Photodynamic Therapy
Photodynamic therapy (PDT) is a clinical treatment that combines the effects of visible light irradiation with subsequent biochemical events that arise from the presence of a photosensitising drug (possessing no dark toxicity) to cause destruction of selected cells. Today, the most common agent used in dermatological PDT is 5-aminolevulinic acid (ALA). As a result of its hydrophilic character, ...
