Review
Pain Experiences of Children and Adolescents with Osteogenesis Imperfecta: An Integrative Review.
Pain is a commonly experienced symptom for children and adolescents diagnosed with osteogenesis imperfecta (OI). The purpose of this integrative review was to describe the pain experience of children and adolescents with OI as well as critically appraise the content and methods of studies assessing OI pain. ⋯ Research on OI has focused very little on pain experience in children and adolescents, and there is no standard method of assessing pain. To better describe the pain experience of these patients, future research should focus on better characterizing OI pain with the use of age-appropriate valid, reliable, and multidimensional pain assessment tools.

Randomized Controlled Trial
Effects of Cognitive-behavioral Therapy (CBT) on Brain Connectivity Supporting Catastrophizing in Fibromyalgia.
Fibromyalgia (FM) is a chronic, common pain disorder characterized by hyperalgesia. A key mechanism by which cognitive-behavioral therapy (CBT) fosters improvement in pain outcomes is via reductions in hyperalgesia and pain-related catastrophizing, a dysfunctional set of cognitive-emotional processes. However, the neural underpinnings of these CBT effects are unclear. Our aim was to assess CBT's effects on the brain circuitry underlying hyperalgesia in FM patients, and to explore the role of treatment-associated reduction in catastrophizing as a contributor to normalization of pain-relevant brain circuitry and clinical improvement. ⋯ The results add to the growing support for the clinically important associations between S1-insula connectivity, clinical pain, and catastrophizing, and suggest that CBT may, in part via reductions in catastrophizing, help to normalize pain-related brain responses in FM.

Comparative Study Clinical Trial
Epidural versus Systemic Analgesia: An International Registry Analysis on Postoperative Pain and Related Perceptions after Abdominal Surgery.
The PAIN OUT registry collected data from >30,000 patients on pain on the first postoperative day in hospitals worldwide. Utilizing the database, we compared systemic and epidural analgesia (EA) on postoperative pain and related side-effects in patients after abdominal surgeries (ASs). ⋯ Regarding the pain intensity, satisfaction, and relatable side-effects, EA seems to be superior compared with systemic analgesia after AS.

Fatigue is known to be a pathway through which depression, psychological distress, pain intensity, and sleep disturbance influence pain interference, but the independent effects of fatigue on pain interference after controlling for these variables remains unknown. In addition, no study to date has tested whether fatigue subtypes of general fatigue, mental fatigue, emotional fatigue, physical fatigue, or vigor differentially predict pain interference. ⋯ The findings suggest that fatigue is an important independent predictor of pain interference and not merely a mediator. These findings also suggest that not all fatigue is created equal. Interventions aimed at reducing pain interference should target specific fatigue symptoms of physical fatigue and vigor. Future research investigating the independent associations of fatigue subtypes on pain outcomes may help clarify the nature of the interrelationships between pain and fatigue.

Previous studies have demonstrated the presence of active trigger points (TrPs) in women with migraine reproducing their headache attacks. No study has investigated whether these TrPs can alter cervical muscle function in migraine. Our objective was to analyze differences in the activation of superficial neck flexor and extensor muscles in women with migraine considering the presence of active TrPs in the splenius capitis (SC), the upper trapezius (UT), and the sternocleidomastoid (SCM) muscles. ⋯ The presence of active TrPs in the cervical musculature determines an altered activation of superficial neck and extensor muscles during low-load, isometric CCF contractions in women with migraine.
