The impact of oral Polypodium leucotomos extract on ultraviolet B response: A human clinical study.

Background: There is a rationale for adding systemic photoprotective agents to the current photoprotection regimen.

Objective: This study was designed to objectively evaluate the molecular and photobiologic effects of oral administration of Polypodium leucotomos extract (PLE).

Methods: In all, 22 subjects with Fitzpatrick skin phototype I to III were enrolled.

The Vitiligo Working Group recommendations for narrowband ultraviolet B light phototherapy treatment of vitiligo.

Background: Treatment of vitiligo with narrowband ultraviolet B light (NBUVB) is an important component of the current standard of care. However, there are no consistent guidelines regarding the dosing and administration of NBUVB in vitiligo, reflected by varied treatment practices around the world.

Objective: To create phototherapy recommendations to facilitate clinical management and identify areas requiring future research.

Exploring the gaps in the evidence-based application of narrowband UVB for the treatment of vitiligo.

While narrowband ultraviolet light B (NB-UVB) has become integral to the treatment of diffuse vitiligo, evidence-based guidelines have been lacking with regard to dosing and administration. This is largely the result of heterogeneous study designs, ambiguous methodologies, disparate dosing strategies, and the use of varied, and somewhat arbitrary, outcome measures. In the absence of prospective trials to address each of these concerns, the available literature regarding the application of NB-UVB for vitiligo was reviewed and the authors now pose a set of questions to the phototherapy community in an attempt to highlight gaps within our understanding.

Role of Recipient-site Preparation Techniques and Post-operative Wound Dressing in the Surgical Management of Vitiligo.

Vitiligo is an acquired skin disorder characterized by the destruction of melanocytes resulting in achromic macules and patches involving the affected skin. Multiple methods of treatments have emerged to manage vitiligo, including medical and surgical techniques. Among the surgical techniques described in the management of vitiligo are minipunch grafting, split-thickness skin grafting, hair follicle transplantation, suction blister grafting, and cultured and non-cultured autologous melanocyte transplantation.

Hepatitis C virus (HCV) infection in hemodialysis patients in the south of Jordan.

Hepatitis C Virus (HCV) infection is a serious public health problem throughout the world. Patients with chronic renal failure are exposed to this infection. This could be due to a failure to identify carriers of this disease or because of lack of implementing truly effective safety measures in the dialysis units.

Association of Interleukin-10 gene promoter polymorphisms in Saudi patients with vitiligo.

The promoter region of human Interleukin -10 gene is highly polymorphic and has been associated with numerous autoimmune diseases. Recent studies have linked vitiligo with defective autoimmune system. This study is aimed to explore a possible association between IL-10 gene polymorphism and vitiligo in Saudi population.
