Dopaminergic signaling is implicated in nociceptive pathways. These effects are mediated largely through dopamine receptors and modulated in part by dopamine transporters. This study tested the hypothesis that genetic variants in the genes encoding dopamine receptor 2 (DRD2) and the dopamine active transporter (SLC6A3) influence acute pain severity after motor vehicle collision. ⋯ Genetic variants in DRD2 are associated with acute pain after a traumatic stressful event. These results suggest that dopaminergic agents may be useful for the treatment of individuals with acute posttraumatic pain as part of a multimodal opioid-sparing analgesic regimen.

This study examined whether the administration of intranasal oxytocin was associated with pain sensitivity, endogenous pain inhibitory capacity, and negative mood states. ⋯ This study incorporated a placebo-controlled, double-blind, within-subjects crossover design with randomized administration of intranasal oxytocin and placebo. The data suggest that the administration of intranasal oxytocin may augment endogenous pain inhibitory capacity and reduce negative mood states including anxiety.

The purpose of this study was to determine baseline adherence to key recommendations from the 2010 VA/DOD Clinical Practice Guideline for Opioid Therapy for Chronic Pain at Veterans Health Administration (VA) facilities. We hoped to understand practice patterns at the time of guideline release to guide quality improvement and implementation efforts. ⋯ In 2010, guideline-recommended practices for opioid prescribing were variably used across VA health care systems. Efforts to disseminate practices used at high-performing sites, and increase consistency of use of recommended practices across patients and facilities should be considered to improve pain management and reduce adverse events.

Persistent postsurgical pain, musculoskeletal pain, sensory disturbances, and lymphedema are major clinical problems after treatment for breast cancer. However, there is little evidence on how these sequelae affects physical function. The aim this study was to develop and validate a procedure-specific tool for assessing the impact of pain and other sequelae on physical function after breast cancer treatment. ⋯ The present scales displayed good psychometric qualities, and may be used to evaluate the impact of specific sequelae after breast cancer treatment on physical functioning, as well as to monitor and target interventions to optimize pain treatment and rehabilitation.
