Medical and physical predictors of localized provoked vulvodynia.

Vulvodynia in young women is a significant clinical challenge. This overview focuses on localized provoked vulvodynia (LPV) with regard to medical and physical predictors of the condition. Several causative factors have been proposed and one major conceptual issue is the role of inflammation. Trauma to the vestibular mucosa causes an initial inflammatory response which may result in peripheral and central pain sensitization. In women with LPV, evidence of mucosal nerve fiber proliferation and enhanced systemic pain perception has been found. A dysfunction of the pelvic floor muscles is common and many patients also suffer from other bodily pain. In general, the level of scientific quality in published studies on vulvodynia is low. Further research on epidemiology, etiology and conduction of clinical trials with high evidence grade is desired.
