Efficacy and Safety of Oral and Transdermal Opioid Analgesics for Musculoskeletal Pain in Older Adults: a Systematic Review of Randomized, Placebo-Controlled Trials
This systematic review with meta-analysis was performed to evaluate the efficacy and safety of using opioid analgesics in older adults with musculoskeletal pain. We searched Cochrane Library, MEDLINE, EMBASE, Web of Science, AMED, CINAHL and LILACS for randomized controlled trial with mean population age of 60 years or older, comparing the efficacy and safety of opioid analgesics with placebo for musculoskeletal pain conditions. Reviewers extracted data, assessed risk of bias and evaluated the quality of evidence using the GRADE approach. (Source: The Journal of Pain)

Children With Chronic Pain: Response Trajectories After Intensive Pain Rehabilitation Treatment
Recent studies provide evidence supporting an intensive pain rehabilitative approach to the management of complex pediatric chronic pain.12,19,29 This approach encompasses daily physical, occupational, and psychological therapy focused on helping children return to premorbid levels of functioning through progressively engaging in previously avoided activities and taking a self-management approach to pain. Intensive pain rehabilitation is time-intensive, costly (>$30,000),6 and often the last hope for families who have not experienced success in outpatient treatment. (Source: The Journal of Pain)
