Review Meta Analysis
Dexmedetomidine as an Adjuvant to Local Anesthetics in Transversus Abdominis Plane Block: A Systematic Review and Meta-analysis.
The objective of this meta-analysis was to evaluate the analgesic effects of dexmedetomidine (DEX) in transversus abdominis plane (TAP) blocks for abdominal surgery. ⋯ DEX is a potential anesthetic adjuvant that can facilitate better postoperative analgesia, reduce postoperative analgesic requirements, and prolong the local anesthetic effect when administered in TAP blocks.

Randomized Controlled Trial
TRPA1 Sensitization Produces Hyperalgesia to Heat but not to Cold Stimuli in Human Volunteers.
Transient receptor potential ion channels play a role in thermal hyperalgesia and are among targets of novel analgesics. However, a role of TRPA1 in either heat or cold hyperalgesia is controversial. In this study, changes in thermal sensitivity were assessed following topical application of a specific sensitizer of TRPA1 and compared with the effects of sensitizers of TRPV1 and TRPM8. ⋯ The observation that the TRPA1 irritant cinnamaldehyde induced heat hyperalgesia at an effect sizes comparable with that of capsaicin attributes TRPA1 a role in human heat-induced pain. Results suggest the inclusion of heat pain as a major efficacy measure in human experimental studies of the effects of TRPA1 antagonists and the development of TRPA1 antagonists for clinical pain settings involving heat hyperalgesia.

Randomized Controlled Trial
Telehealth Therapy Effects of Nurses and Mental Health Professionals From 2 Randomized Controlled Trials for Chronic Back Pain.
To compare the efficacy of mental health professional versus primary care nurse-delivered telehealth cognitive-behavioral therapy (CBT) and supportive care (SC) treatments for chronic low back pain, using data from 2 separate randomized controlled trials. Both trials were completed in the same hospital and used the same study design, research team, and outcome measures. ⋯ Results from these clinical trials suggest that the benefits of home-based, telehealth-delivered CBT and SC treatments for chronic back pain were comparable when delivered by a primary care nurse or mental health professional.

The aims of this study were: (1) to investigate the association between the rs4680 Val158Met polymorphism in frequent episodic tension-type headache (FETTH) and chronic tension-type headache (CTTH); and (2) to analyze the association between the rs4680 Val158Met polymorphism with clinical, psychological, or psychophysical variables. ⋯ The Val158Met polymorphism (rs4680) does not appear to be involved in predisposition to tension-type headache; however, this genetic factor may be involved in the pathogenesis expression of CTTH, as greater pressure pain sensitivity and higher depressive levels were found in CTTH carrying the Met/Met genotype.

Multidisciplinary treatment programs for provoked vestibulodynia (PVD) are recommended, yet few have been evaluated. This study examined women's symptom trajectories over time, as well as baseline demographic, psychosocial and pain characteristics as predictors/ moderators of sexual pain and distress following treatment at a clinic using multidisciplinary concurrent methods. We also examined the impact of baseline variables on the probability of having low sexual distress scores following treatment. ⋯ Although global improvements were observed, women with poorer baseline sexual functioning were less likely to improve after multidisciplinary treatment.
