The purpose of the present study was to assess vaginal resting pressure (VRP), pelvic floor muscle (PFM) strength and endurance, and surface EMG activity in women with and without provoked vestibulodynia (PVD). ⋯ Young, nulliparous women with PVD had significantly higher VRP, but this finding was not confirmed by vaginal surface EMG.

Although in-depth qualitative information is critical to understanding patients' symptom experiences and to developing patient-centered outcome measures, only one previous qualitative study has assessed urological chronic pelvic pain syndrome (UCPPS) symptom exacerbations ("flares"). ⋯ Given their negative impact, future research should focus on approaches to prevent flares, and to reduce their frequency, severity, and/or duration. Patients' quality of life may also be improved by providing them with a sense of control over their symptoms through ready access to flare medications/therapy, and by engaging them socially.

Neosaxitoxin is a phycotoxin whose molecular mechanism of action shows a reversible inhibition of voltage-gated sodium channels at the axonal level, impeding nerve impulse propagation. This study was designed to evaluate the clinical efficacy of neosaxitoxin as a long-acting pain blocker in the treatment of bladder pain syndrome (BPS). ⋯ Neosaxitoxin infiltration was shown to be a safe and effective intervention to control pain related to BPS. It was well tolerated by patients, who experienced extended pain relief and associated beneficial effects over a follow-up of 90 days. These results confirm the effectiveness of neosaxitoxin as a long-acting local pain blocker.

Standard external landmarks have been suggested as a guide for in-office percutaneous nerve evaluation (PNE), but validity of these landmarks has not been assessed. Our objective was to determine whether the standard 9 cm from the tip of the coccyx indicates the position of the S3 sacral foramen and whether other boney landmarks and measurements improved positioning. ⋯ A distance 9 cm from the tip of the coccyx is a reasonable starting landmark for in-office blind PNE. However, given the variability in coccyx length, caution should be taken; also, sensory-motor response is necessary to confirm proper placement.
