Comparative StudyFeasibility of ultrasound-guided percutaneous placement of peripheral nerve stimulation electrodes and anchoring during simulated movement: part two, upper extremity.
Peripheral nerve stimulation (PNS) may provide analgesia for neuropathic pain syndromes in that nerve distribution. PNS electrode placement using ultrasound (US) guidance for upper extremity pain syndromes has not been reported. Existing anchoring technology may allow permanent implantation without significant migration. ⋯ This new minimally invasive approach to lead placement requires further study to determine implantation criteria, optimal locations, anchoring techniques, and electrode design to define best clinical practice.

An ultrasound study of the phrenic nerve in the posterior cervical triangle: implications for the interscalene brachial plexus block.
Concomitant phrenic nerve block frequently occurs after brachial plexus block procedures in the neck and can result in substantial morbidity. In this study we sought to establish the anatomic basis using ultrasound imaging. ⋯ This descriptive study found that the phrenic nerve and brachial plexus are within 2 mm of each other at the cricoid cartilage level, with additional 3 mm separation for every cm more caudal in the neck. Clinical trials with imaging guidance are needed to establish whether brachial plexus selective blocks can be consistently achieved above the clavicle.

Review Meta AnalysisPregabalin as a treatment for painful diabetic peripheral neuropathy: a meta-analysis.
Painful diabetic peripheral neuropathy (DPN) is an increasingly prevalent disorder that is best managed through a multimodal approach. We examined the effects of pregabalin on pain control, sleep disturbance, and the patient's global impression of change (PGIC) for the treatment of this disorder. ⋯ Pregabalin has significant effects on the pain associated with DPN as well as secondary endpoints that affect patients' quality of life.
