Vitiligo is a common and chronic disease with a great impact on patients' quality of life. Phototherapy with narrowband ultraviolet B radiation and excimer laser are two treatment modalities that are used increasingly for the management of the disease with variable results. In this article, we review the efficacy, adverse effects, and possible mechanisms of action of narrowband ultraviolet B an...

background: jaundice is one of the most common problems occurring in the neonatal period. it is commonly managed by phototherapy with its inherent complications. however, this treatment modality may itself result in the development of hypocalcaemia and create serious complications including convulsion and related conditions. objective: to determine the effect of phototherapy on serum calcium le...

Novel treatment strategies and new information concerning the management of moderate to severe psoriasis justify a reassessment of the role of the classic therapies in this setting. This consensus statement evaluates narrowband UV-B therapy, which is currently considered the phototherapy option of choice in psoriasis because of its risk-to-benefit ratio. The role of excimer laser and photodynam...

Phototherapy treatment using low intensity visible red light (laser) for wound healing is well known. However, its worldwide use is prohibitively expensive and requires a clinical setting. Using a handy, safe and inexpensive non-coherent low level narrow band red light device (LLRL), we performed a prospective clinical trial on 53 patients suffering from Acne Vulgaris. The patients were divided...

308nm xenon-chloride excimer laser, a novel mode of phototherapy, is an ultraviolet B radiation system consisting of a noble gas and halide. The aim of this systematic review was to investigate the literature and summarize all the experiments, clinical trials and case reports on 308-nm excimer laser in dermatological disorders. 308-nm excimer laser has currently a verified efficacy in treating ...

Impaired wound healing is a common complication associated with diabetes with complex pathophysiological underlying mechanisms and often necessitates amputation. With the advancement in laser technology, irradiation of these wounds with low-intensity laser irradiation (LILI) or phototherapy, has shown a vast improvement in wound healing. At the correct laser parameters, LILI has shown to increa...

Abstract As a key branch of the cross-discipline biophotonics, phototherapy, including photodynamic therapy (PDT), and photothermal (PTT), is promising in biomedicine visible light-driving PDT has been applied to clinical treatment. However, extensive applications phototherapy are limited by hypoxic microenvironment, laser penetration depth, potential complexity for combined PDT/PTT. Thus, NIR-...

treatment with antimicrobial chemotherapeutic agents, alternative approaches such as lethal photosensitization are being used. the aim of this study was to evaluate the effect of visible light and laser beam radiation in conjugation with three different photosensitizers on the survival of two main periodontopathogenic bacteria including porphyromonas gingivalis and fusobacterium nucleatum in di...
