ReviewMethodological and statistical characteristics of meta-analyses on spinal cord stimulation for chronic pain: a systematic review.
A growing number of meta-analyses (MA) have investigated the use of spinal cord stimulation (SCS) as a treatment modality for chronic pain. The quality of these MAs has not been assessed by validated appraisal tools. ⋯ CRD42023431155.

Postdural puncture headache (PDPH) is a relatively common acute complication that occurs following regional anesthesia and is among the clinical features of secondary intracranial hypotension syndrome (IHS).The aim of this study was to document the radiological findings specific to PDPH with brain MRI and to determine whether these findings differed from those described in the third edition of the International Headache Society's International Classification of Headache Disorders (ICHD-3). ⋯ The radiological characteristics of IHS and PDPH are most likely the result of compensatory mechanisms in response to decreased cerebrospinal fluid pressure. The acute nature of PDPH probably causes its radiological MRI characteristics to differ from those of IHS, given that no brain sagging could be demonstrated.

Plantar compartment block for hallux valgus surgery: a proof-of-concept anatomic and clinical study.
Hallux valgus surgery is associated with moderate to severe postoperative pain. We hypothesized that a plantar compartment block may be a good technique for postoperative analgesia. We describe an anatomic approach to ultrasound-guided plantar compartment block and assess the clinical efficacy of the block for outpatient surgery. ⋯ This anatomic description of the ultrasound-guided plantar compartment block reported the injection area to target the medial and lateral plantar nerves with 5 mL of local anesthetic. Normal walking without assistance is attained rapidly with this regional anesthesia technique, and the time to request postoperative analgesia after hallux valgus surgery is long.

Paravertebral and erector spinae plane blocks decrease length of stay compared with local infiltration analgesia in autologous breast reconstruction.
Autologous breast reconstruction is associated with significant pain impeding early recovery. Our objective was to evaluate the impact of replacing surgeon-administered local infiltration with preoperative paravertebral (PVB) and erector spinae plane (ESP) blocks for latissimus dorsi myocutaneous flap reconstruction. ⋯ Replacing surgical infiltration with PVB and ESP blocks for autologous breast reconstruction reduces LOS. The comparable reduction in LOS suggests that ESP may be a viable alternative to PVB in patients undergoing latissimus flap breast reconstruction following mastectomy. Further research should investigate whether ESP or PVB have better patient outcomes in complex breast reconstruction.
