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.

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.

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.

Previous studies have found widespread pain processing alterations in the brain in chronic low back pain (cLBP) patients. We aimed to (1) identify brain regions showing altered amplitude of low-frequency fluctuations (ALFF) using MRI and use these regions to discriminate cLBP patients from healthy controls (HCs) and (2) identify brain regions that are sensitive to cLBP pain intensity changes. ⋯ Brain low-frequency oscillations in the PCL, SMA, PoG, PrG, and ACC may be associated with the neuropathology of cLBP. Low-frequency oscillations in the insula, amygdala, hippocampal/parahippocampal gyrus, thalamus, and DMN are sensitive to manoeuvre-induced spontaneous back pain intensity changes.
