School anxiety is a prevalent and debilitating mental health problem among youth with chronic pain. Despite evidence that anxiety in the context of school is associated with significant school-related disability, no studies have examined specific aspects of school anxiety in a pediatric chronic pain population. ⋯ Present results offer a nuanced perspective into the underlying sources of school anxiety among adolescents with chronic pain. Our findings may inform future research efforts and targeted school functioning interventions. In particular, findings suggest that an individualized approach to the assessment of school anxiety which considers the unique sources of anxiety (eg, social vs. academic) may lay the groundwork for the refinement of school functioning interventions in pediatric chronic pain.

Understanding the molecular biology of opioid analgesia is essential for its proper implementation and mechanistic approach to its modulation in order to maximize analgesia and minimize undesired effects. By appreciating the molecular mechanisms intrinsic to opioid analgesia, one can manipulate a molecular target to augment or diminish a specific effect using adjuvant drugs, select an appropriate opioid for opioid rotation or define a molecular target for new opioid drug development. In this review, we present the cellular and molecular mechanisms of opioid analgesia and that of the associated phenomena of tolerance, dependence, and hyperalgesia. The specific mechanisms highlighted are those that presently can be clinically addressed.

Pediatric neuropathic pain is caused by a spectrum of disorders that are generally challenging to treat. Many of the underlying altered neurological processes are being elucidated through mechanistic studies. ⋯ Our clinical experience and typical risk versus benefit considerations suggest a limited, if any, role for using opioids to treat pediatric neuropathic pain. In this literature review, we review the available adult and pediatric data and provide general guidance on this subject matter.

A relationship between sleep and pain is well established. A better understanding of the mechanisms that link sleep and pain intensity is urgently needed to optimize pain management interventions. The objective of this systematic review was to identify, synthesize, and critically appraise studies that have investigated putative mediators on the path between sleep and pain intensity. ⋯ A growing body of research is applying mediation analysis to elucidate mechanistic pathways between sleep and pain intensity. Currently sparse evidence would be illuminated by more intensively collected longitudinal data and improvements in analysis.
