Intrathecal (IT) opioid pumps are one therapeutic cornerstone of refractory nonmalignant pain syndromes. The aim of this study was to evaluate the efficacy of and surgical and pharmacological complications of IT pumps beyond a time span of 10 years. ⋯ Even after a time span of over 15 years and several exchanges of pump systems, pain intensity was still reduced. After 3 years, IT drug dose remained unchanged with low side-effect and complication rates.

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.

Radiotherapy for metastatic bone pain can induce a transitory increase in pain known as pain flare. Several studies have described the use of prophylactic corticosteroids to prevent pain flare. However, the role and efficacy of corticosteroids to prevent pain flare remain unclear. ⋯ Overall, the findings of this systematic review indicate that glucocorticoids appear to be an effective prophylactic treatment to prevent pain flare in patients undergoing radiotherapy for bone metastases. New CT are needed to confirm these results and to determine the optimal dose of dexamethasone.

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.
