This systematic review aims to examine the available literature and to synthesize published data concerning the treatment of Complex Regional Pain Syndrome (CRPS) with ketamine. ⋯ There is no high quality evidence available evaluating the efficacy of ketamine for CRPS and all manuscripts examined in this review were of moderate to low quality. Therefore, we conclude there is currently only weak evidence supporting the efficacy of ketamine for CRPS, yet there is clearly a rationale for definitive study.

Pain intensity is commonly rated on an 11-point Numerical Pain Rating Scale which can be expressed as a calculated percentage pain reduction (CPPR), or by patient-reported percentage pain reduction (PRPPR). We aimed to determine the agreement between CPPR and PRPPR in quantifying musculoskeletal pain improvement at short-term follow-up after a corticosteroid injection. ⋯ PRPPR may not agree with CPPR at 3 week follow-up, as these individuals tend to report a higher estimated percentage improvement compared to the value calculated from their pain scores.

The cost of caring for patients with chronic pain conditions poses a significant burden to both the healthcare system and patients. We were interested in analyzing the financial costs and benefits of treating these patients in a comprehensive outpatient pain rehabilitation program. ⋯ The appropriate use of a comprehensive outpatient rehabilitation program for chronic pain patients can result in a significant reduction in medical costs.

Randomized Controlled Trial
Aerobic exercise and cold pressor test induce hypoalgesia in active and inactive men and women.
Physical inactivity is a risk factor for chronic pain. Several mechanisms play a role in pain chronification including impairment of pain inhibition. ⋯ Cold pressor stimulation and aerobic exercise caused comparable multisegmental increases in PPT in active and inactive men and women. The CPM and EIH responses were correlated, but they have different temporal manifestation of hypoalgesia.

Review Case Reports
Deconstructing chronic low back pain in the older adult--step by step evidence and expert-based recommendations for evaluation and treatment: part I: Hip osteoarthritis.
To present the first in a series of articles designed to deconstruct chronic low back pain (CLBP) in older adults. The series presents CLBP as a syndrome, a final common pathway for the expression of multiple contributors rather than a disease localized exclusively to the lumbosacral spine. Each article addresses one of twelve important contributors to pain and disability in older adults with CLBP. This article focuses on hip osteoarthritis (OA). ⋯ Hip OA is common and should be evaluated routinely in the older adult with CLBP so that appropriately targeted treatment can be designed.
