Localized Provoked Vulvodynia: Association With Nerve Growth Factor and Transient Receptor Potential Vanilloid Type 1 Genes Polymorphisms.

Objective: The aim of the study was to study the associations between localized provoked vulvodynia (LPV) and several single-nucleotide polymorphisms (SNPs) in the transient receptor potential vanilloid type 1 (TRPV1), nerve growth factor (NGF), and the heparanase (HPSE) genes.

Materials And Methods: Prevalence of SNPs among 65 women with moderate or severe primary LPV (initial symptoms occur with first provoking physical contact) and 126 healthy, ethnically matched controls was analyzed in an observational case-control study. Each participant answered a questionnaire addressing familial LPV occurrence and comorbid pain conditions.

Topical nifedipine for the treatment of localized provoked vulvodynia: a placebo-controlled study.

Unlabelled: Topical application of the calcium antagonist nifedipine has demonstrated effectiveness in treating chronic anal fissure, without adverse effects. Like chronic anal fissure, vulvodynia is associated with muscle hypertonicity and an inflammatory infiltrate. We conducted a double-blind placebo-controlled study to investigate the effectiveness of 2 concentrations of topical nifedipine cream in the treatment of vulvodynia.
