The experience of pain is believed to be influenced by psychologic and genetic factors. A previous study suggested pain catastrophizing and catechol-O-methyltransferase (COMT) genotype influenced clinical pain ratings for patients seeking operative treatment of shoulder pain. This study investigated whether these same psychologic and genetic factors predicted responses to induced shoulder pain. ⋯ These findings from an experimental model converge with those from a surgical cohort and provide additional evidence that the presence of elevated pain catastrophizing and COMT diplotype indicative of low COMT enzyme activity have the potential to increase the risk of developing chronic pain syndromes.

Children with developmental delay are often unable to verbalize pain or advocate for themselves owing to cognitive, motor, or verbal limitations, which puts them at increased risk for poor pain assessment and management. Although patient-controlled analgesia has been shown to be safe, effective, and superior to intermittent opioid dosing, not all children can operate patient-controlled analgesia independently. Parent/nurse-controlled analgesia (PNCA) may be an option for these children. However, the safety and efficacy of PNCA have not been thoroughly evaluated and many practitioners are reluctant to use it. ⋯ Pain scores, side effects, and adverse events suggest that PNCA may be an effective method of pain control for children with developmental delay. Diligent monitoring and education are crucial to ensure safety.
