Randomized Controlled Trial
Mathematical Validation and Credibility of Diagnostic Blocks for Spinal Pain.
Diagnostic blocks are used in different ways for the diagnosis of spinal pain, but their validity has not been fully evaluated. ⋯ Randomized, comparative local anesthetic blocks offer a credibility of 75%, but randomized, placebo-controlled blocks provide a credibility of 95%, and are thereby suitable as a criterion standard for diagnostic blocks.

OBJECTIVES : This study translates the Pain Catastrophizing Scale (PCS) into Hindi and examines the psychometric properties of the translated version (Hindi PCS [Hi-PCS]) in patients with chronic low back pain (CLBP). METHODS : Forward and backward translations were performed from English to Hindi according to standard methodology. A final version was evaluated by a committee of clinical experts and Hi-PCS was then pilot-tested in 10 patients with CLBP. ⋯ Intraclass correlation coefficient for the Hi-PCS is 0.923 (95% CI: 0.875-0.953). Hi-PCS was moderately correlated with pain intensity (r = 0.651) and functional disability (r = 0.352), and negatively correlated with QoL (r = -0.380). CONCLUSIONS : PCS translation and cross-cultural adaptation to Hindi demonstrated good factor structure along adequate psychometric properties and could be recommended for use in CLBP research in India.

Mindfulness Meditation and Cognitive Behavioral Therapy Intervention Reduces Pain Severity and Sensitivity in Opioid-Treated Chronic Low Back Pain: Pilot Findings from a Randomized Controlled Trial.
To assess benefits of mindfulness meditation and cognitive behavioral therapy (CBT)-based intervention for opioid-treated chronic low back pain (CLBP). ⋯ Meditation-CBT intervention reduced pain severity and sensitivity to experimental thermal pain stimuli in patients with opioid-treated CLBP.

SoluMatrix® Diclofenac: Sustained Opioid-Sparing Effects in a Phase 3 Study in Patients with Postoperative Pain.
To evaluate opioid rescue medication usage and the opioid-sparing effect of low-dose SoluMatrix(®) diclofenac developed using SoluMatrix Fine Particle Technology™ in a phase 3 study in patients experiencing pain following bunionectomy surgery. ⋯ The opioid-sparing effect following low-dose SoluMatrix diclofenac (35 mg or 18 mg three times daily) administration was evaluated in patients experiencing pain following bunionectomy. Significantly fewer patients receiving SoluMatrix diclofenac or celecoxib (400 mg loading, 200 mg twice daily) required rescue medication during 0-24 h and >24-48 h following bunionectomy compared with placebo. No serious adverse events were reported among patients who received SoluMatrix diclofenac. SoluMatrix diclofenac may reduce opioid usage in the postoperative setting in patients with acute pain.

Sacroiliac joint (SIJ) injections have been used to provide short-term relief of SIJ pain. In this study, the authors investigated a new technique using a superior approach. ⋯ The superior approach consistently achieves good access to the SI joint, and achieves outcomes that are compatible with those of other techniques. The superior approach constitutes an alternative to other techniques for injections into the SI joint.
