Association between socioeconomic status and treatment in patients with low back or neck pain: a population-based cross-sectional study in South Korea.
Socioeconomic status affects the treatment of patients with low back pain and/or neck pain. We examined the relationship between socioeconomic status (occupation and household income level) and treatments such as chronic opioid use and interventional procedures among these patients. ⋯ Socioeconomic status factors are associated with treatment in patients with low back pain and/or neck pain.

Cadaveric study investigating the femoral nerve-sparing volume for pericapsular nerve group (PENG) block.
This cadaveric study investigated the maximum effective volume of dye in 90% of cases (MEV90) required to stain the iliac bone between the anterior inferior iliac spine (AIIS) and the iliopubic eminence (IPE) while sparing the femoral nerve during the performance of pericapsular nerve group (PENG) block. ⋯ For PENG block, the MEV90 of methylene blue required to spare the femoral nerve in a cadaveric model is 13.2 mL. Further studies are required to correlate this finding with the MEV90 of local anesthetic in live subjects.

ReviewAnalgesia for the Bayesian Brain: How Predictive Coding Offers Insights Into the Subjectivity of Pain.
In order to better treat pain, we must understand its architecture and pathways. Many modulatory approaches of pain management strategies are only poorly understood. This review aims to provide a theoretical framework of pain perception and modulation in order to assist in clinical understanding and research of analgesia and anesthesia. ⋯ Limitations of traditional models for pain have driven the application of new data analysis models. The Bayesian principle of predictive coding has found increasing application in neuroscientific research, providing a promising theoretical background for the principles of consciousness and perception. It can be applied to the subjective perception of pain. Pain perception can be viewed as a continuous hierarchical process of bottom-up sensory inputs colliding with top-down modulations and prior experiences, involving multiple cortical and subcortical hubs of the pain matrix. Predictive coding provides a mathematical model for this interplay.

ReviewWhen Does Intervention End and Surgery Begin? The Role of Interventional Pain Management in the Treatment of Spine Pathology.
Recent advances in the field of interventional pain management (IPM) involve minimally invasive procedures such as percutaneous lumbar decompression, interspinous spacer placement, interspinous-interlaminar fusion and sacroiliac joint fusion. These developments have received pushback from surgical professional societies, who state spinal instrumentation and arthrodesis should only be performed by spine surgeons. The purpose of this review is to evaluate the validity of this claim. A literature search was conducted on Google Scholar and PubMed databases. Articles were included which examined IPM in the following contexts: credentialing and procedural privileging guidelines, fellowship training and education, and procedural outcomes compared to those of surgical specialties. Our primary research question is: "Should interventionalists be performing decompression and fusion procedures?". ⋯ Advanced percutaneous spine procedures are not universally incorporated into pain fellowship curriculums. Trainees attempt to compensate for these deficiencies through industry-led training, which has been criticized for lacking central regulation. There is also a paucity of studies comparing procedural outcomes between surgeons and interventionalists for complex spine procedures, including decompression and fusion. Pain fellowship curriculums have not kept pace with some of procedural advancements within the field. Interventionalists are also not trained to manage potential complications of spinal instrumentation and arthrodesis, which has been recognized as an essential requirement for procedural privileging. Decompression and fusion may therefore be outside the scope of an interventionalist's practice.

This article summarizes the many initiatives and achievements of the International Association for the Study of Pain (IASP) in pain education worldwide since 1973. These range from major events such as the World Congress on Pain that attracts thousands of attendees to the more intimate and focused Pain Schools and Pain Camps. ⋯ The unique contribution of IASP to the study of pain is reflected in its consistent focus on a biopsychosocial approach to pain, the promotion of interactions between basic scientists and clinicians, as well as multidisciplinary and interdisciplinary collaborations. Details of these rich offerings can be found on the IASP web site, and this article provides a guide for those seeking to access them.
