Review Multicenter Study
Biphosphonates for the therapy of complex regional pain syndrome I--systematic review.
Several studies found that biphosphonates counteract locally increased bone resorption and associated pain in patients with complex regional pain syndrome I (CRPS I). We performed a systematic review of all randomised controlled trials to assess the benefit of biphosphonates in the treatment of CRPS I patients with bone loss. ⋯ The very limited data reviewed showed that bisphosphonates have the potential to reduce pain associated with bone loss in patients with CRPS I. However, at present there is not sufficient evidence to recommend their use in practice.

Randomized Controlled Trial Multicenter Study
A randomised controlled trial with prolonged-release oral oxycodone and naloxone to prevent and reverse opioid-induced constipation.
Opioid-induced constipation can have a major negative impact on patients' quality of life. This randomised, double-blinded study evaluated the analgesic efficacy of prolonged-release (PR) oral oxycodone when co-administered with PR oral naloxone, and its impact on opioid-induced constipation in patients with severe chronic pain. Another objective was to identify the optimal dose ratio of oxycodone and naloxone. ⋯ Co-administration of PR oral naloxone and PR oral oxycodone is associated with a significant improvement in bowel function compared with PR oral oxycodone alone, with no reduction in the analgesic efficacy of oxycodone.
