Complex regional pain syndrome (CRPS) is a life-altering condition that usually affects the extremities after a trauma or nerve injury. The physiologic changes that occur as a result of the inciting injury are complex, as the name of the syndrome implies. ⋯ We review recent developments in the understanding of CRPS and advancements in management of this syndrome. Further research in targeting specific mechanisms involved in the pathophysiology of CRPS should lead to prevention of this condition.

Comment Review
Effectiveness of interdisciplinary interventions in paediatric chronic pain management: a systematic review and subset meta-analysis.
Paediatric chronic pain is a significant problem that can have devastating impacts on quality of life. Multimodal interdisciplinary interventions are the mainstay of paediatric treatment. The aim of this article is to provide a comprehensive review of the effectiveness of interdisciplinary interventions in the management of paediatric chronic pain. ⋯ Overall, interdisciplinary interventions show promise in providing a range of clinical benefits for children with chronic pain. Methodologically robust randomised controlled trials using standardised outcome measures are needed, however, to guide clinical care.

Randomized Controlled Trial
Analgesic potential of PF-06372865, an α2/α3/α5 subtype-selective GABAA partial agonist, in humans.
This study investigated the analgesic effects of two doses (15 and 65 mg) of PF-06372865, a novel α2/α3/α5 gamma-aminobutyric acid A (GABAA) subunit selective partial positive allosteric modulator (PAM), compared with placebo and pregabalin (300 mg) as a positive control. ⋯ NCT0223871.

Trigeminal neuralgia (TN) can have a significant impact on wellbeing and quality of life. Limited data exist for treatments that improve TN pain acutely, within 24 h of administration. This systematic review aims to identify effective treatments that acutely relieve TN exacerbations. ⋯ Several treatment options exist that may provide fast and safe relief of TN. Future studies should report on outcomes within 24 h to improve knowledge of the acute analgesic TN treatments.

Randomized Controlled Trial
The association between decrease in cerebral oxygen saturation during cardiac surgery and postoperative cognitive dysfunction: secondary analysis of a randomised trial.
Postoperative cognitive dysfunction (POCD) occurs commonly after cardiac surgery. Near-infrared spectroscopy (NIRS) has been used to monitor regional cerebral oxygen saturation (rScO2) in order to minimise the occurrence of POCD by applying dedicated interventions when rScO2 decreases. However, the association between rScO2 intraoperatively and POCD has not been clarified. ⋯ NCT02185885.
