Pudendal neuralgia (PN) is an impairing neuropathic disorder, affecting both men and women, involving a severe burning and sharp pain along the course of the pudendal nerve. Treatment is often insufficient, and options are limited. Pulsed radiofrequency (PRF) is a technique which might be useful in therapy. ⋯ At long-term follow-up, 89% of the patients described their condition as "(very) much better." No serious side effects were observed. In conclusion, PRF is a successful treatment option in patients not responding to standard treatment options, including pudendal nerve blocks. PRF of the pudendal nerve can be used for PN to provide relief in patients' chronic pelvic pain.

Transforaminal epidural steroid injection (TFESI) is widely practiced for the treatment of radicular pain. As its effectiveness is still subject to debate, a better patient selection for TFESI is necessary. We aimed to evaluate the potential of bedside-suitable qualitative sensory testing (QualST) to determine the early effectiveness of TFESI for the treatment of chronic lumbosacral radiculopathy (LSR)-related pain. ⋯ QualST might be clinically applicable for detecting patient subgroups that could differ in the early treatment results of radicular pain by TFESI.

Hospitalized patients with opioid use disorder who present with acute pain are challenging to manage. Without any treatment, their mortality in the first 28 days after discharge is substantially increased. Unlike extended-release naltrexone, which requires a period of withdrawal, or methadone, which can cause prolonged corrected QT (QTc) and carries a higher risk of respiratory depression, buprenorphine provides potent analgesia with low respiratory risk. ⋯ Our acute pain management service uses multimodal analgesia to maintain adequate analgesia and minimize withdrawal during buprenorphine induction in the hospital. With the assistance of narcotics addiction rehabilitation program specialists, we help link patients to outpatient buprenorphine providers and maximize the chance of successful recovery. The primary outcome of this study was to determine the percentage of patients who filled an outpatient buprenorphine prescription after undergoing inpatient induction.

Review Case Reports
Dorsal Root Ganglion Stimulation for Erythromelalgia Related Foot Pain: A Case Report and Review of the Literature.
Erythromelalgia is a rare neurovascular disorder characterized by erythema, warmth, and episodic burning pain, often felt in the face, hands, and feet. Symptoms are typically worse with heat, exercise, stress, and during the overnight hours. ⋯ To our knowledge, the use of dorsal root ganglion (DRG) stimulation for erythromelalgia-related pain has not been described. Herein, we present a case of erythromelalgia-related pain at the bilateral plantar surfaces of the feet, which was treated successfully with bilateral sacral S1 nerve root DRG stimulation.

Review Case Reports
Parascapular Sub-Iliocostalis Plane Block: Comparative Description of a Novel Technique for Posterior Rib Fractures.
We describe a new analgesic technique, parascapular sub-iliocostalis plane block (PSIP), for lateral-posterior rib fractures as an alternative to other regional techniques in a high-risk patient who suffered a decompensation of her cardiorespiratory function after posterior chest trauma. We performed a continuous ultrasound-guided left PSIP block in the sub-iliocostalis plane next to the fourth rib to optimize analgesia and minimize complications. ⋯ The efficacy of the PSIP block may potentially depend on different mechanisms of action: (1) direct action in the fracture site by craniocaudal myofascial spread underneath the erector spinae muscle (ESM); (2) spread to deep layers through tissue disruption caused by trauma, to reach the proximal intercostal nerves; (3) further medial spread through deeper layers to the midline to block the posterior and ventral spinal nerves; (4) medial spread below the ESM, to reach the posterior spinal nerves (more reliably than rhomboid intercostal / sub-serratus [RISS] block); and (5) lateral spread in the sub-serratus (SS) plane to reach the lateral cutaneous branches of the intercostal nerves; while avoiding significant negative hemodynamic effects associated with techniques such as the paravertebral block (PVB), erector spinae plane (ESP) block or its variations, or thoracic epidural analgesia (TEA). A comparative comprehensive overview of the regional techniques described for posterior chest trauma is presented, including TEA, PVB, ESP block, retrolaminar block, mid-point to transverse process block, costotransverse foramen block, RISS, and serratus anterior plane (SAP) block.
