Increased Hyperalgesia and Proinflammatory Cytokines in the Spinal Cord and Dorsal Root Ganglion After Surgery and/or Fentanyl Administration in Rats.
Perioperative fentanyl has been reported to induce hyperalgesia and increase postoperative pain. In this study, we tried to investigate behavioral hyperalgesia, the expression of proinflammatory cytokines, such as interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α), and the activation of microglia in the spinal cord and dorsal root ganglion (DRG) in a rat model of surgical plantar incision with or without perioperative fentanyl. ⋯ The surgical plantar incision with or without perioperative fentanyl induced significant mechanical and thermal hyperalgesia, an increased expression of IL-1β, IL-6, TNF-α in the spinal cord and DRG, and activation of microglia in the spinal cord.

Comparative Study
Intradural spinal tumors - a review of post-operative outcomes comparing intramedullary and extramedullary tumors from a single institution's experience.
Intradural spinal tumors are rare and can be classified into extramedullary or intramedullary. They commonly present with symptoms such as intractable back pain or neurologic deficits. We retrospectively reviewed 91 cases of intradural spinal tumors that underwent surgery in our institution from 2011 to 2016 and assessed their clinical outcomes. ⋯ We achieved gross total resection in the majority of patients with both extramedullary and intramedullary tumors (65.4% vs. 70%, P = 0.91). Patients younger than 65 years (odds ratio [OR] 4.40, confidence interval [CI] 0.72-26.9, P = 0.11) and those who had complete resection of tumor (OR 2.92, CI 0.61-14.0, P = 0.18) were associated with higher odds of improved clinical outcomes, but the results were not statistically significant. The use of intraoperative neurophysiologic monitoring was not associated with improved neurologic outcomes compared with cases where it was not used (OR 0.56, CI 0.10-3.05, P = 0.50).

TAP block has gained popularity to provide postoperative analgesia after abdominal surgery but its advantage over epidural analgesia is disputed. For lower abdominal surgeries, epidural analgesia has been the gold standard and time-tested technique for providing postoperative analgesia, but contraindications for the same would warrant need for other equally good analgesic techniques. The objective of this study is to compare the analgesic efficacy of both the techniques. ⋯ The epidural anaesthesia is still the golden standard to achieve a postcaesarean analgesia. Epidural anaesthesia is a considerably effective method in controlling the postoperative pain. We are of the opinion that epidural anaesthesia should be preferred in the first place to achieve a successful postcaesarean analgesia as it provides more effective pain control.

OPRM1-A118G polymorphism (A > G, rs1799971) is associated with interindividual variability in both response to postoperative pain and opioid treatment. The aim of this meta-analysis is to identify the predictive strength in the current literature of OPRM1-A118G polymorphism to postoperative anesthetic reactions, including nausea, vomiting, pruritus and dizziness. ⋯ OPRM1-A118G polymorphism (A > G) is associated with a reduced risk of postoperative vomiting, but not nausea, pruritus and dizziness. The results should be interpreted with caution due to limited sample and possible heterogeneity between the included studies. Well-designed and large-scale studies are necessary to confirm our results.

To identify and describe the characteristics of existing practices for postoperative weight bearing and management of tibial plateau fractures (TPFs), identify gaps in the literature, and inform the design of future research. ⋯ Postoperative rehabilitation for TPFs most commonly involves significant non-weight bearing time before full weight bearing is recommended at 9-12 weeks. Partial weight bearing protocols and brace use were varied. Type of rehabilitation may be an important factor influencing recovery, with future high quality prospective studies required to determine the impact of different protocols on clinical and radiological outcomes.
