Few studies have investigated the relationship between injury location, mechanism and their association with complex regional pain syndrome (CRPS). We conducted a nationwide database survey to explore this issue. ⋯ Injury in the extremities rather than the trunk is an important risk factor for CRPS. Certain injury mechanisms confer higher risk of CRPS. This nationwide study demonstrated that injury increased CRPS nearly threefold. Open wound, sprain and strain, superficial injury, contusion, and nerve and spinal cord injury are main injury mechanisms. Injury in the extremities confers a higher risk of CRPS.

Comparative Study
Volunteers in Palliative Care - A Comparison of Seven European Countries: A Descriptive Study.
In Europe, volunteers have an important role in the delivery of palliative care. As part of the EU co-funded Europall project, 4 aspects of volunteering in palliative care were studied for 7 European countries (Belgium, England, France, Germany, the Netherlands, Poland, and Spain). These included (1) involvement of volunteers in palliative care, (2) organization of palliative care volunteering, (3) legal regulations concerning volunteering, and (4) education and training of palliative care volunteering. ⋯ This study provides a descriptive overview of volunteer work in palliative care in 7 European countries, with a focus on the organizational aspects. Further research should concentrate on the roles and responsibilities of volunteers in the care for the terminally ill in different European health systems.

Observational Study
Influence of Centrally Mediated Symptoms on Postoperative Pain in Osteoarthritis Patients Undergoing Total Knee Arthroplasty: A Prospective Observational Evaluation.
Central sensitization plays an important role in the chronic pain experienced by osteoarthritis (OA) patients. In this prospective observational study, we investigated the influence of the level of preoperative centrally mediated symptoms measured by the Central Sensitization Inventory (CSI) on pain intensity after total knee arthroplasty (TKA) for OA. ⋯ OA patients with high levels of comorbid centrally mediated symptoms showed severe pain and increased analgesic requirements after TKA in the early postoperative period. Moreover, these patients seemed to be at higher risk of persistent pain, and a high CSI score was predictive of low patient satisfaction in terms of pain relief after surgery.

Pain has variously been used as a means of punishment, extracting information, or testing commitment, as a tool for education and social control, as a commodity for sacrifice, and as a draw for sport and entertainment. Attitudes concerning these uses have undergone major changes in the modern era. Normative convictions on what is right and wrong are generally attributed to religious tradition or to secular-humanist reasoning. ⋯ Social convention and other environmental influences, with their idiosyncrasies, are a more recent, ever-changing overlay. We close with an example in which details on the neurobiology of pain processing, specifically the question of where in the brain the experience of pain is generated, affect decision making in end-of-life situations. By separating innate biological substrates from culturally imposed attitudes (memes), we may arrive at a more reasoned approach to a morality of pain prevention.

Randomized Controlled Trial
Efficacy and Tolerability of Subcutaneous Methylnaltrexone in Patients with Advanced Illness and Opioid-Induced Constipation: A Responder Analysis of 2 Randomized, Placebo-Controlled Trials.
Subcutaneous methylnaltrexone is efficacious and well tolerated in inducing bowel movements in patients with advanced illness and opioid-induced constipation (OIC); factors determining optimal responsiveness to OIC treatment, however, have not been elucidated. This post hoc responder analysis examined the influence of demographic and baseline characteristics on methylnaltrexone efficacy and tolerability in this population. ⋯ Subcutaneous methylnaltrexone provides a rapid, robust, and consistent RFBM response in patients with advanced illness and OIC. Methylnaltrexone 0.30 mg/kg may elicit particularly favorable responses in select patient populations.
