Low back pain (LBP) is a major healthcare problem causing tremendous economic costs. ⋯ Burning and prickling were revealed as possible indicators for LBP chronicity. Combined with pain attacks and pressure pain, these 4 pain descriptors might be a promising adjunct to pain intensity in terms of outcome parameters for future LBP studies. The decrease of neuropathic pain syndromes in the elderly might be explained by degenerative processes. The presented work provides important insights on LBP management in the acute, subacute, and chronic stages.

Two well-known spinal cord stimulation (SCS) paradigms, conventional (Con) and burst SCS, are hypothesized to exert their antinociceptive effects through different stimulation-induced mechanisms. We studied the course of the behavioral antinociceptive effect during 60 minutes of SCS and 30 minutes post-SCS in a rat model of chronic neuropathic pain. ⋯ To conclude, biphasic burst SCS results in a delayed antinociceptive effect after onset of the stimulation, as compared with Con SCS, in a chronic neuropathic pain model. Furthermore, biphasic burst SCS seems to exhibit a delayed wash-out of analgesia after stimulation is turned off.

Randomized Controlled Trial
Ultrasound-Guided Intercostal Nerve Block Following Esophagectomy for Acute Postoperative Pain Relief in the Postanesthesia Care Unit.
To explore the feasibility, effectiveness, and safety of ultrasound-guided intercostal nerve block (ICNB) for immediate relief of moderate and severe pain following esophagectomy in a postanesthesia care unit (PACU). ⋯ Ultrasound-guided ICNB could provide effective and safe pain relief for patients who suffer from moderate to severe pain (VAS score ≥ 5) after esophagectomy in the PACU.

Lead fracture is a well-known complication of cylindrical spinal cord stimulator leads. In order to reduce this complication, anchor design and techniques have been modified, but internal lead design has received little attention. ⋯ MLC lead design has the potential to significantly mitigate lead fracture.
