Randomized Controlled Trial
Effects of a person-centred approach in a school setting for adolescents with chronic pain - The HOPE randomized controlled trial.
Chronic pain among adolescents is common but effective interventions applicable in a school setting are rare. Person-centred care (PCC) is a key factor in improving health by engaging persons as partners in their own care. ⋯ This study evaluates the effects of a pain management programme based on a PCC approach in a school setting addressing adolescents at upper secondary and secondary schools with chronic pain. No overall effects were shown, but results illustrate that the intervention improved self-efficacy in adolescents at secondary school. Implementation of a PCC approach in a school setting may have the potential to improve self-efficacy in daily activities for adolescents with chronic pain at secondary school.

Unilateral injection of Complete Freund's Adjuvant (CFA) into the intra-plantar surface of the rodent hindpaw elicits chronic inflammation and hyperalgesia in the ipsilateral hindlimb. Mechanisms contributing to this hyperalgesia may act over multiple time courses and can include changes in ion channel expression and post-translational SUMOylation. Hyperpolarization-activated, cyclic nucleotide-gated (HCN) channels mediate the hyperpolarization-activated current, Ih . An HCN2-mediated increase in C-nociceptor Ih contributes to mechanical hyperalgesia in the CFA model of inflammatory pain. Changes in HCN2 post-translational SUMOylation and protein expression have not been systematically documented for a given dorsal root ganglia (DRG) throughout the time course of inflammation. ⋯ Nociceptor HCN2 channels mediate an increase in Ih that is necessary for mechanical hyperalgesia in a CFA model of chronic pain, but the mechanisms producing the increase in nociceptor Ih have not been resolved. The data presented here suggest that the increase in Ih during the early stages of inflammation may be mediated by an increase in HCN2 protein expression and post-translational SUMOylation.
