We searched the medical literature from the last 15 years (1998 to 2013) relating to the etiology, diagnosis, and treatment of vulvodynia. The evidence was reviewed supporting the therapeutic proposals currently in use and propose the incorporation of novel, minimally invasive, interventional therapies, within the context of a multidisciplinary approach. ⋯ The optimal therapy for vulvar pain syndrome remains elusive, with low percentages of therapeutic success, using either local or systemic pharmacological approaches. Surgery involving invasive and often irreversible therapeutic procedures has resulted in success for certain subtypes of vulvodynia. We present a multidisciplinary approach whereby pain treatment units may provide an intermediate level of care between standard medical and surgical treatments.

Sleep disturbances are particularly troublesome in patients with painful rheumatic disease. This article reviews the literature specifically published on sleep disturbances in osteoarthritis, a prevalent pathology and leading cause of disability. ⋯ When needed, a specific treatment of sleep disorders should be associated with an optimal management of pain to achieve synergistic improvements in quality of life. More large-scale studies are needed to identify predictive factors of sleep impairment in osteoarthritis.

The patient health questionnaire (PHQ) is designed for screening psychopathology in primary care settings. However, little is known about its clinical utility in other chronic pain populations, which usually have high psychiatric comorbidities. ⋯ The strong specificity of the PHQ appears to be its primary strength for this cohort. Due to its high specificity, the PHQ could be employed as an additional screening tool to help rule out potential psychiatric comorbidity in patients with CDOMD. The low sensitivity of the PHQ in this population, however, remains a weakness of the PHQ.

Randomized Controlled Trial
Twelve-Month Follow-Up of a Randomized Trial Assessing Cooled Radiofrequency Denervation as a Treatment for Sacroiliac Region Pain.
The objective of this study was to report the long-term outcomes of cooled radiofrequency (CRF) lateral branch neurotomy (LBN) as a treatment for sacroiliac (SI) region pain. Whereas the 1-, 3-, 6-, and 9-month outcomes of this procedure compared to sham treatment were previously reported, this current report shows the 12-month outcomes of CRF/LBN treatment for SI region pain. ⋯ These favorable 12-month results illustrate the durability of effective CRF/LBN-mediated treatment of SI region pain for selected patients. Furthermore, successful CRF/LBN treatments in unblinded crossover study subjects demonstrate the unlikelihood that such positive outcomes are attributable to a "placebo" effect, and suggest that CRF/LBN is an effective therapeutic option for alleviating pain, and improving physical function and quality of life, with few complications.

The important pathophysiologic factor of neurogenic intermittent claudication (NIC) in lumbar spinal canal stenosis (LSCS) has been reported to be the reduction in intraneural blood flow and a state of relative ischemia in nerve tissues. Prostaglandin E1 (PGE1) presumably improves symptoms in patients with LSCS by improving the blood flow in the cauda equina and nerve roots through its vasodilation and antiplatelet aggregation effects. The purpose of the study was to summarize the results of previous studies regarding PGE1 treatment for LSCS and to describe the details of PGE1 treatment to all physicians who take care of patients with LSCS. ⋯ Based on the results of previous studies, PGE1 treatment may be an option as a conservative treatment for LSCS. However, future studies with high-quality and long-term follow-up are necessary. Future studies also should include refinement of indications, administration period, as well as comparisons between PGE1 treatment and other conservative treatments such as epidural injection.
