Illusion-enhanced Virtual Reality Exercise for Neck Pain: A Replicated Single Case Series.
Body illusions have shown promise in treating some chronic pain conditions. We hypothesized that neck exercises performed in virtual reality (VR) with visual feedback of rotation amplified would reduce persistent neck pain. ⋯ Our hypothesis, that neck exercises performed in VR with visual feedback of rotation amplified, would reduce persistent neck pain was not supported. Possible explanations and future directions are discussed.

Effects of Adding Oxycodone to Ropivacaine on Labor Analgesia: A Randomized Controlled Trial.
It's known that the addition of opiates to LA improves epidural analgesia in labour. This trial should have compared oxycodone to fentanyl.

The Benefit of Dexmedetomidine on Postoperative Cognitive Function is Unrelated to the Modulation on Peripheral Inflammation: A Single Center, Prospective, Randomized Study.
Dexmedetomidine potentially confers an advantage to reduce the incidence of postoperative delirium (POD) in surgical patients. Anti-inflammation is important effect of this sedative drug. In this study, we aimed to investigate whether the effect of dexmedetomidine on the postoperative cognitive function is via inhibiting peripheral inflammation. ⋯ Intraoperative sedation with dexmedetomidine conferred better postoperative neurocognitive function for elderly patients who received total knee arthroplasty. This effect was unrelated to the modulation of dexmedetomidine on peripheral inflammation.

Deceptive and Nondeceptive Placebos to Reduce Pain: An Experimental Study in Healthy Individuals.
Recent research has shown that placebos can be effective even if they are openly prescribed to participants. Yet, it is unclear how such "open-label placebos" (OLPs) compare to deceptive placebo (DP) and what the mechanisms of actions are. In this study, we therefore compared 2 versions of OLP to DP and no treatment (NT). ⋯ The study provided evidence for traditional placebo analgesia on the basis of deception. For OLP, we found that OLP indeed increased pain tolerance; however, participants receiving OLP were reluctant to report any subjective analgesic effects. Combined with previous studies, the present findings suggest that the effects of OLP are weaker in healthy volunteers than in clinical samples.
