Interdisciplinary pain rehabilitation programs are an evidence-based biopsychosocial treatment approach for chronic pain. The purpose of the current study is to assess outcomes for a 10-week interdisciplinary, acceptance and commitment therapy (ACT)-based, outpatient treatment model and to evaluate the relationship between psychological process variables (ie, pain catastrophizing, pain acceptance, pain self-efficacy) and treatment outcomes. ⋯ This study supports a 10-week, ACT-based treatment model for interdisciplinary chronic pain rehabilitation. In addition, pain catastrophizing, pain acceptance, and pain self-efficacy were each found to be mechanisms by which individuals achieve successful treatment outcomes. This research provides further support for interdisciplinary rehabilitation approaches for chronic pain.

Caudal epidural blocks often fail due to the difficulty of appropriate needle insertion. This study aimed to evaluate the anatomy of the sacral hiatus using ultrasound imaging. ⋯ The mean distance from the skin to the sacral cornua and BMI were found to be associated with the palpability of the sacral hiatus, and sacral base protrusion was demonstrated to be associated with the difficulty of needle insertion into the sacral hiatus.

Lumbar adhesive arachnoiditis is a debilitating neuropathic condition and is difficult to diagnose owing to lack of definitive diagnostic criteria. By focusing on the intrathecal mobility of nerve roots, we assessed whether useful diagnostic criteria could be established using MRI. ⋯ In patients with a known risk for lumbar adhesive arachnoiditis, nerve roots lose their potential to migrate in the dural sac in the gravitational force direction on MRI.

Musculoskeletal conditions are well documented in inflammatory bowel disease (IBD). However, whether IBD activity influences musculoskeletal pain experiences is uncertain. Central sensitization has been proposed in patients with IBD who are suffering from persistent pain. Identification of central sensitization symptomology using the Central Sensitization Inventory (CSI) has been reported in many pain-related disorders. Aims of this study were to explore predictive relationships between IBD activity and musculoskeletal pain experiences (severity/interference), and the mediating effects of the CSI. ⋯ Active IBD demonstrated a positive association with worse musculoskeletal pain experiences. The CSI demonstrated significant mediation between active IBD and pain severity. Additionally, the CSI and pain severity demonstrated significant mediation between active IBD and pain interference. This suggests that symptoms of central sensitization significantly influence musculoskeletal pain experiences in IBD.

Ketamine, a potent analgesic and N-methyl-D-aspartate-(NMDA)-receptor antagonist, improves analgesic outcomes in patients with complex regional pain syndrome (CRPS). The NMDA receptor has also been implicated in opioid withdrawal. The use of ketamine to assist with a rapid opioid taper in the setting of CRPS has not been previously described. ⋯ CRPS may involve catecholamine hypersensitivity and central sensitization and can be notoriously challenging to treat by itself even outside of the context of an opioid taper. The patient we describe here received one additional 5-day infusion at 6 months and remained opioid-free while experiencing a major improvement in function and lifestyle that he still maintains. This was possible through a combination of aggressive inpatient management with ketamine as the centerpiece, followed by consistent outpatient CBT to maintain results without the need for a return to opioids. This combination has previously not been described in the setting of a rapid opioid taper and this patient's underlying CRPS made it all the more remarkable.
