ReviewAdjuncts to local anesthetic wound infiltration for postoperative analgesia: a systematic review.
Local anesthetics (LAs) are commonly infiltrated into surgical wounds for postsurgical analgesia. While many adjuncts to LA agents have been studied, it is unclear which adjuncts are most effective for co-infiltration to improve and prolong analgesia. We performed a systematic review on adjuncts (excluding epinephrine) to local infiltrative anesthesia to determine their analgesic efficacy and opioid-sparing properties. ⋯ Our findings suggest benefits of several adjuncts to local infiltrative anesthesia for postoperative analgesia. Further well-powered RCTs are needed to compare various infiltration regimens and agents.

Factors associated with academic rank among chronic pain medicine faculty in the USA.
Numerous factors are considered in the academic promotion of pain medicine physicians. In this study, we investigated the importance of research productivity, career duration, leadership, and gender on attaining professorship in chronic pain medicine fellowship programs in the USA. ⋯ Our study shows that, higher h-index, publication citations, division chief position, affiliation at a lower tier medical school, and location in the Western region were independently associated with full professorship, whereas gender was not. The identified variables for professorship may be considered as factors in faculty promotions.

Case ReportsLocal anesthetic resistance in a Crohn's patient undergoing cesarean delivery.
Patient resistance to local anesthetics is rarely considered as the cause of regional anesthesia failure. ⋯ Resistance to local anesthetics may be more common than we think, especially among patients with chronic pain. Providers should consider local anesthetic resistance when regional anesthesia is unsuccessful. Further research is needed to determine if skin wheal tests and/or a different local anesthetic could improve results.

5-HT1A receptor-mediated attenuation of heat hyperalgesia and mechanical allodynia by chrysin in mice with experimental mononeuropathy.
Persistent neuropathic pain poses a health problem, for which effective therapy or antidote is in dire need. This work aimed to investigate the pain-relieving effect of chrysin, a natural flavonoid with monoamine oxidase inhibitory activity, in an experimental model of neuropathic pain and elucidate mechanism(s). ⋯ These findings confirm the antihyperalgesic and antiallodynic efficacies of chrysin, with spinal 5-HT1A receptors being critically engaged.
