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
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.

The Multidimensional Pain Inventory (MPI) is frequently used in the assessment of chronic pain. Three subgroups have been derived from MPI: adaptive coper (AC), dysfunctional (DYS), and interpersonally distressed (ID). The primary aim of this study was to examine whether outcome of Interdisciplinary Multimodal Pain Rehabilitation Programs (IMMRPs) differed across the MPI subgroups. ⋯ The validity of the MPI subgroups was partially confirmed. DYS and ID had the most severe clinical presentations at baseline and showed most improvement following IMMRP, but overall severity in DYS and ID at post-treatment was still higher than in the AC group. Future studies should examine how processes captured by MPI interact with neurobiological, medical, sociodemographic, and adaptation/coping factors and how these interactions impact severity of chronic pain and treatment outcome.

Randomized Controlled Trial
Comparison of ultrasound-guided type-II pectoral nerve block and rhomboid intercostal block for pain management following breast cancer surgery: a randomized, controlled trial.
Although breast-conserving surgery-axillary dissection (BCS-AD) is a minimally invasive surgery, patients may suffer from moderate-to-severe pain. Several regional techniques can be used for pain control. The type II pectoral nerve block (PECS II) and the rhomboid intercostal block (RIB) are interfascial plane blocks that have been reported to provide effective analgesia after breast surgery. This study aims to compare the analgesic efficacy of the PECS II block and the RIB after breast surgery. ⋯ The PECS II block and the RIB provide similar effective analgesia after BCS-AD.
