Utilization of Our Toolkit: A Systematic Review and Meta-analysis of Surgical Therapies in Vitiligo Treatment.

BACKGROUND: Although vitiligo is often treated medically, there is increasing evidence for surgical therapies. Overlap with in-office surgical therapies that are already employed for other dermatologic conditions suggest that there is a significant opportunity to expand dermatologists' therapeutic repertoire for vitiligo. OBJECTIVE: To systematically review the efficacy of nonphototherapy surgical treatments for vitiligo in comparative or placebo-controlled trials. METHODS: A systematic review for surgical treatments for vitiligo was conducted. Primary outcomes were treatment success (>75% repigmentation) and failure (<25% repigmentation) for which meta-analyses were performed. Adverse effects were noted. The Cochrane risk of bias tool was used to assess study quality. RESULTS: Surgical treatments reviewed included platelet-rich plasma, microneedling, ablative therapies, and surgical modalities. Seventy-three studies with 2,911 patients were included. The repigmentation benefits and adverse events are summarized. Meta-analyses suggest benefits for ablative laser therapies or microneedling in combination with narrowband ultraviolet B (NB-UVB) and for suction blister epidermal grafting over punch grafting. CONCLUSION: The addition of microneedling or ablative laser therapy to NB-UVB phototherapy may improve repigmentation with minimal adverse effects. Surgical therapies, such as suction blister grafting and punch grafting, may offer the highest likelihood of repigmentation but have a risk of adverse effects including scarring and hyperpigmentation.

Molecular Targets and Natural Compounds in Drug Development for the Treatment of Inflammatory Pain.

This chapter explores therapeutic targets and the anti-inflammatory nature of some naturally- occurring compounds and the current or potential use of these compounds in the treatment of chronic inflammatory pain states. We will review the mechanisms of chronic inflammatory pain, the molecular targets of selected natural compounds in inhibiting inflammatory pain, and the traditional and current approaches to treating pain using these compounds. Previous research on experimental as well as clinical pain will be summarized from in vitro to animal and human models. Potential areas for further research will also be discussed.
