In 2015, we evaluated our practices regarding pain after breast-conserving surgery. Thereafter, we have adapted our practices by performing a systematic deep serratus plane block before the surgical incision. In 2019, we assessed the impact of these changes in terms of chronic pain. The main objective of this study was to evaluate the prevalence of chronic pain 3 months after this type of surgery. ⋯ No persistent pain at 3 months was reported in 69% of cases. Furthermore, the use of a deep serratus anterior plane block before the surgical incision has limited the need for morphine titration in the recovery room to <1 patient in 5. These evaluations of professional practices should be encouraged.

Neuropathic pain is a debilitating symptom reported by patients presenting with postherpetic neuralgia (PHN). Efforts to alleviate this pain have been projected to lie in individualization of pharmacological treatment through pain phenotyping and subsequent investigations into the genetic basis of postherpetic neuralgia therapy. ⋯ Knowledge and application of genetic variations in postherpetic neuralgia - structural proteins and genes can aid in ascertaining risk, susceptibility to, severity of and protection from postherpetic neuralgia. This review summarizes the most recent information that has been published on phenotypes and genotypes with possible clinical applications and directions for future research.

Randomized Controlled Trial
Evaluation of Analgesic Efficacy and Opioid-sparing Effect of Duloxetine After Arthroscopic Rotator Cuff Repair: A Randomized Clinical Trial.
This study aimed to evaluate the analgesic efficacy and opioid-sparing effect of duloxetine in adults having arthroscopic rotator cuff repair, as well as its clinical safety. ⋯ For patients undergoing arthroscopic rotator cuff repairs, duloxetine resulted in a significant reduction in pain within postoperative 2 days, but the reduction was not clinically meaningful. Duloxetine did not decrease the opioid consumption within postoperative 2 days and did not increase the risk of bleeding within postoperative 2 days. The incidence of nausea and vomiting in the duloxetine group was significantly greater than that in the placebo group.

Success rates of spinal surgeries to treat chronic back pain are highly variable and useable prognostic indicators are lacking. We aimed to identify and evaluate preoperative predictors of pain and disability after spinal surgery for chronic low back/leg pain. ⋯ In conclusion, absence of spinal stenosis potentially predicts greater pain relief and preoperative sensory loss likely predicts reduction in disability. Overall, QoE for most identified associations was low/very low.
