Comparative Study
The COMFORT-behavior scale is useful to assess pain and distress in 0- to 3-year-old children with Down syndrome.
Many pediatric intensive care units use the COMFORT-Behavior scale (COMFORT-B) to assess pain in 0- to 3-year-old children. The objective of this study was to determine whether this scale is also valid for the assessment of pain in 0- to 3-year-old children with Down syndrome. These children often undergo cardiac or intestinal surgery early in life and therefore admission to a pediatric intensive care unit. ⋯ Cutoff values for the COMFORT-B set at 17 or higher discriminated between pain (NRS pain of 4 or higher) and no pain (NRS pain below 4) in both groups. We concluded that the COMFORT-B scale is also valid for 0- to 3-year-old children with Down syndrome. This makes it even more useful in the pediatric intensive care unit setting, doing away with the need to apply another instrument for those children younger than 3.

Case Reports Randomized Controlled Trial Comparative Study
Drug-induced liver injury following a repeated course of ketamine treatment for chronic pain in CRPS type 1 patients: a report of 3 cases.
Studies on the efficacy of ketamine in the treatment of chronic pain indicate that prolonged or repetitive infusions are required to ensure prolonged pain relief. Few studies address ketamine-induced toxicity. Here we present data on the occurrence of ketamine-induced liver injury during repeated administrations of S(+)-ketamine for treatment of chronic pain in patients with complex regional pain syndrome type 1 as part of a larger study exploring possible time frames for ketamine re-administration. ⋯ In all patients, the ketamine infusion was promptly terminated and the liver enzymes slowly returned to reference values within 2 months. Our data suggest an increased risk for development of ketamine-induced liver injury when the infusion is prolonged and/or repeated within a short time frame. Regular measurements of liver function are therefore required during such treatments.

Comparative Study
Chronic pain in adults with an intellectual disability: prevalence, impact, and health service use based on caregiver report.
This study examined chronic pain in adults with an intellectual disability (ID), in terms of its prevalence, impact on physical and psychological functioning, and treatments used. Questionnaires were distributed to 2378 primary caregivers (caregivers) of community-dwelling adults with an ID. The questionnaires were used to gather data on demographics, general health, nature of pain, impact of pain, treatment, and health-related decision making. ⋯ A significant proportion of individuals with chronic pain also experienced limitations in several aspects of daily living, and more than 78% of caregivers reported that the service user had become upset or distressed by pain. More than 80% of service users were receiving some form of treatment for their pain, with most seeing a family physician and using analgesics as the primary form of pain treatment. Results indicate that chronic pain is a significant problem for persons with an ID, with a proportion of service users living with daily pain for many years and experiencing limitations in daily functioning, emotional well-being, and quality of life.

Comparative Study
Sex differences in perceived pain are affected by an anxious brain.
Decades of research confirm that women have greater pain sensitivity than men. Women also show greater overall anxiety sensitivity than men. Given these differences, we hypothesized that sex differences in anxiety would explain sex differences in experienced pain and physiological responses to pain (at both spinal and cortical levels). ⋯ This means that stable predispositions to respond with heightened apprehension contribute to baseline pain sensitivity differences between the sexes. These results indicate that the modulatory effect of affect on pain-related brain processes may explain why men and women experience painful shocks so differently. In our study, the mediating role of anxiety on sex differences in pain was tested and confirmed using path analysis.
