The benefit of intradiscal glucocorticoid injection (IGI) for discogenic low back pain (LBP) remains controversial. ⋯ Low back pain, lumbar back pain, intradiscal glucocorticoid injection, modic changes, meta-analysis.

The sacroiliac joint is one of the proven causes of low back and lower extremity pain, ranging from 10% to 25% in patients with persistent axial low back pain without disc herniation, discogenic pain, or radiculitis. Despite the difficulty of diagnosis, multiple therapeutic modalities including surgical and nonsurgical interventions have been utilized. Among the interventional modalities, intraarticular injections are commonly utilized. ⋯ Chronic low back pain, sacroiliac joint pain, sacroiliac joint dysfunction, sacroiliitis, sacroiliac joint injection, sacroiliac joint nerve blocks, radiofrequency ablation, conventional radiofrequency, pulsed radiofrequency.

Various percutaneous intradiscal procedures have been implemented to manage lumbosacral discogenic pain. But most of these procedures simply end up manipulating the central nucleus pulposus or the inner annulus, instead of accessing the posterior outer annulus where the actual, major pain generators exist. Thus, more localized percutaneous techniques, specifically derived to address the pathologic tissues creeped between the torn, posterior annulus and hyperplastic sinuvertebral nerve, have been devised. However, the clinical effectiveness of these "more" accurate procedures is still skeptical. ⋯ Discogenic pain, minimal invasive technique, percutaneous targeted disc decompression, systematic review, meta-analysis.

Post-traumatic trigeminal neuropathic pain (PTNP) following trigeminal neuralgia (TN)-related neuroablative procedures is relatively rare. Due to the fear of debilitating complications, its treatment has been generally suboptimal. Pregabalin (PGB) has been reported to relieve neuropathic pain. However, the potential role of PGB and the predictors of response of PGB use as a strategy in the treatment of PTNP following TN-related neuroablative procedures have not been identified yet. ⋯ Post-traumatic trigeminal neuropathic pain, efficacy, safety, predictor of response, pregabalin.

Low-dose ketamine infusion (LDKI) has shown effectiveness for treating acute pain associated with surgical and nonsurgical (traumatic, neuropathic, and acute cancer-related) origin as an adjuvant to opioids. The increasing use of LDKI as an opioid-sparing agent in multimodal analgesia requires a better understanding of its effects on the cardiovascular response, a known dose-dependent side effect of ketamine administration. We investigated the cardiovascular response of acute pain patients treated with LDKI. ⋯ Ketamine, adverse effects, tachycardia, hypertension, postoperative pain, chronic postsurgical pain.
