People with chronic pain may experience impairments in high-level cognitive skills, particularly executive functions. Such impairments are not adequately measured in most clinical pain management settings yet could be a key influence on everyday functioning. We administered a well-validated, well-normed self-report measure to determine which aspects of executive functioning are compromised in the daily experience of patients with chronic pain, and whether these are associated with pain severity, medications, and mood. ⋯ Multiple factors impact on self-reported executive problems in this population. Specific deficits in Working Memory and Emotional Control have implications for patient engagement with treatment, and retention of information provided in therapy. A screening tool like the BRIEF-A may be useful in pain management settings.

Several mechanisms of remifentanil-induced hyperalgesia in spinal cord mainly have been explained such as N-methyl-D-aspartate receptors activation, but the mechanism in dorsal root ganglion (DRG) is poorly understood. It has been reported that CCL3 may be a regulator in both inflammatory pain and hyperalgesia. In this paper we explored whether CCL3 and CCR5, the mainly receptor of CCL3, play a role in the remifentanil-induced hyperalgesia in DRG by using a rat model with remifentanil administration. ⋯ The results highlighted the fact that CCL3 and its receptor CCR5 in DRG might contribute to remifentanil-induced hyperalgesia. Thus CCL3/CCR5 signaling may be further considered in the development of new therapeutic strategies.

Evidence-based pain-limiting strategies for pediatric immunizations remain underutilized, with barriers identified to date mostly pertaining to health care providers and systems of care. The present study sought to quantify and investigate parent attitudes toward pain management as another potential barrier to the routine use of pain-mitigating strategies during immunizations. ⋯ Some parents perceive limited value in trying to reduce pain during immunizations such that they may be hesitant to invest much time or effort in interventions. Greater success of translating evidence-based pain management into practice therefore may require accounting for differences in parent attitudes by tailoring educational efforts and pain management options accordingly.

The Pelvis and Beyond: Musculoskeletal Tender Points in Women with Chronic Pelvic Pain.
To determine the feasibility of a detailed pain sensitivity assessment using body-wide musculoskeletal tender points (TPs) in women with different types of chronic pelvic pain (CPP) and compare phenotypic differences. ⋯ Detailed musculoskeletal evaluation of women with CPP is feasible and well tolerated. Careful phenotyping differentiated BPS, MPP, and BPS+MPP groups. Attending to the differences between these groups clinically may lead to more effective treatment strategies and improved outcomes for patients with CPP.

Remifentanil is an ultra-short-acting opioid that is used commonly during both short-term and prolonged surgery. This review investigated associations of intraoperative remifentanil administration with acute postoperative pain, hyperalgesia, and chronic postoperative pain, with emphasis on the perioperative coanesthetic drug regimen used. ⋯ Although studies are diverse and sample sizes small, coanesthetics used in combination with remifentanil may influence the occurrence of postoperative hyperalgesia. No firm conclusions could be made regarding acute and chronic pain, indicating that further research with the goal to investigate the effect of volatile or intravenous anesthetics along with simultaneous remifentanil infusion on acute and chronic postoperative pain is needed.
