Review
Dorsal root ganglion stimulation for the treatment of chronic pelvic pain: A systematic review.
Chronic pelvic pain (CPP) is a difficult condition to treat. Due to complex pelvic innervation, dorsal column spinal cord stimulation (SCS) has not been shown to produce the same effect as dorsal root ganglion stimulation (DRGS) given emerging evidence suggesting that applying DRGS may result in favorable outcomes for individuals with CPP. The aim of this systematic review is to investigate the clinical use and effectiveness of DRGS for patients with CPP. ⋯ Dorsal root ganglion stimulation for CPP continues to lack supportive evidence from well-designed, high-quality studies and recommendations from consensus committee experts. However, we present consistent evidence from level IV studies showing success with the use of DRGS for CPP in reducing pain symptoms along with reports of improved QOL through periods as short as 2 months to as long as 3 years. Because the available studies at this time are of low quality with a high risk of bias, we strongly recommend the facilitation of high-quality studies with larger sample sizes in order to better ascertain the utility of DRGS for this specific patient population. At the same time, from a clinical perspective, it may be reasonable and appropriate to evaluate patients for DRGS candidacy on a case-by-case basis, especially those patients who report CPP symptoms that are refractory to noninterventional measures and who may not be ideal candidates for other forms of neuromodulation.

This prospective longitudinal study compares outcomes between Medicare beneficiaries receiving percutaneous image-guided lumbar decompression (PILD) using the mild® procedure and a control group of patients receiving interspinous spacers for the treatment of lumbar spinal stenosis (LSS) with neurogenic claudication (NC). ⋯ This comprehensive study of real-world Medicare claims data demonstrated a significantly lower rate of harms for the mild procedure compared to interspinous spacers for patients diagnosed with LSS with NC, and a similar rate of subsequent interventions during 2-year follow-up.

An abnormal increase in spontaneous neurotransmission can induce subsynaptic knots in the myocyte called myofascial trigger points. The treatment of choice is to destroy these trigger points by inserting needles. However, 10% of the population has a phobia of needles, blood, or injuries. Therefore, the objective of this study is to verify the usefulness of shock waves in the treatment of myofascial trigger points. ⋯ Shock waves seem to be a suitable treatment for myofascial trigger points. In the present study, with a single session of shock waves, very relevant results have been obtained, both functional (normalization of spontaneous neurotransmission) and morphological (disappearance of myofascial trigger points). Patients with a phobia of needles, blood, or injuries who cannot benefit from dry needling may turn to noninvasive radial shock wave treatment.

Case Reports
Cryoneurolysis of alveolar nerves for chronic dental pain: A new technique and a case series.
Chronic neuropathic dental pain has a poor prognosis with a low chance of significant spontaneous improvement. Local or oral therapies may be efficient, however short in terms of duration with potential side effects. Cryoneurolysis has been described to prevent acute postoperative pain or to treat some chronic pain conditions; however, application to dental orofacial pain has not been reported so far. ⋯ Cryoneurolysis on alveolar nerves is a safe and easy-to-use technique allowing prolonged neuropathic pain relief after dental surgery.

Sexual dysfunction is common for patients experiencing chronic pain. Prior research is limited on how treatment for chronic pain affects patients' sexual functioning. This study reports pre-/post-treatment measures of self-reported sexual functioning among individuals presenting for chronic pain treatment at an interdisciplinary pain rehabilitation program (IPRP) and reports patient treatment preferences. ⋯ Findings demonstrate that usual multidisciplinary pain management treatment is not sufficient to address patients' concerns with sexual functioning. Additional creative strategies will need to be studied on how to best treat these overlapping problems. Implications and future research directions are discussed.
