Randomized Controlled Trial
Effects of a Tailored Positive Psychology Intervention on Well-being and Pain in Individuals with Chronic Pain and a Physical Disability: A Feasibility Trial.
To determine the feasibility, acceptability, and efficacy of a computer-based positive psychology intervention in individuals with a physical disability and chronic pain. ⋯ The results support the feasibility, acceptability, and potential efficacy of a computer-based positive psychology intervention for improving well-being and pain-related outcomes in individuals with physical disabilities and chronic pain, and indicate that a full trial of the intervention is warranted.

Opioid-induced pruritus is a common side effect of opioid treatment in patients with acute pain associated with surgery or childbirth. There are several options available to treat opioid-induced pruritus, including nalbuphine. However, it is not known whether nalbuphine offers greater efficacy in treating pruritus without attenuation of analgesia and an increase in the incidence of adverse outcomes. ⋯ Nalbuphine is superior in treating opioid-induced pruritus when compared with placebo, control, diphenhydramine, naloxone, or propofol in patients receiving neuraxial opioids for acute pain related to surgery or childbirth. Therefore, it is recommended that nalbuphine should be used as a first-line treatment of opioid-induced pruritus.

Comparative Study
Hypoalgesia After Exercise and the Cold Pressor Test is Reduced in Chronic Musculoskeletal Pain Patients With High Pain Sensitivity.
In chronic pain patients, impaired conditioned pain modulation (CPM) and exercise-induced hypoalgesia (EIH) have been reported. No studies have compared CPM and EIH in chronic musculoskeletal pain patients with high pain sensitivity (HPS) and low pain sensitivity (LPS). ⋯ CPM and EIH were partly impaired in chronic pain patients with high versus less pain sensitivity, suggesting that the CPM and EIH responses depend on the degree of pain sensitivity. This has clinical implications as clinicians should evaluate pain sensitivity when considering treatment options utilizing the descending modulatory pain control.

The scope of this literature review was to assess the safety and the efficacy of spinal cord stimulation (SCS) for the treatment of chronic pain syndromes originating from refractory angina pectoris and peripheral vascular disease compared with conservative management. ⋯ SCS is a minimally invasive and reversible pain intervention. On the basis of the current literature, SCS may be an alternative treatment strategy in refractory angina pectoris and peripheral vascular disease patients, presenting a low surgical risk profile. However, further clinical trials with larger sample sizes and extended follow-up are required to confirm this finding.

To examine: (1) the relationships between habitual approach to activity engagement and specific aspects of physical functioning in chronic pain; and (2) whether or not these relationships differ according to pain duration. ⋯ The results of this study do not support the commonly held notion that avoidance and/or overactivity behavior leads to deconditioning and reduced physical capacity over time. Findings do, however, suggest that a relationship exists between avoidance and/or overactivity behavior and reduced participation in activities. Implications for the clinical management of chronic pain and directions for further research are discussed.
