The objective of this prospective, open-label study was to determine the long-term effect of medicinal cannabis treatment on pain and functional outcomes in participants with treatment-resistant chronic pain. ⋯ The treatment of chronic pain with medicinal cannabis in this open-label, prospective cohort resulted in improved pain and functional outcomes, and a significant reduction in opioid use. Results suggest long-term benefit of cannabis treatment in this group of patients, but the study's noncontrolled nature should be considered when extrapolating the results.

The Analgesia Nociception Index (ANI), based on heart rate (HR) variability analysis, is known to decrease after a painful stimulus during surgery under general anesthesia in adults. It is measured continuously and noninvasively. We studied ANI response to procedural pain in a pediatric population and ANI measurement's feasibility in this context, across age. ⋯ In this pilot study, ANI measurement seems relevant in pediatric procedural pain, across age. Further studies are needed to confirm these results.

To explore the existence of subgroups in a cohort with chronic low back pain (n=294) based upon data from multiple psychological questionnaires, and profile subgroups on data from multiple dimensions. ⋯ Clinical implications relating to presentations of each cluster are postulated.

Emotional responses to pain are known to play an important role in the development and maintenance of pain. To better understand the role that pain anxiety plays in chronic pain, as well as to evaluate treatments that might treat it effectively, reliable and valid measures of pain anxiety are needed. Thus, the aim of this study was to provide additional evidence regarding the psychometric properties of the Child Pain Anxiety Symptoms Scale (CPASS) in a sample of adolescents. ⋯ The findings support the reliability and the validity of CPASS as a measure of pain-related anxiety in adolescents.
