Randomized Controlled Trial
The Effect of Adding Dexmedetomidine to Levobupivacaine for Interscalene Block for Postoperative Pain Management After Arthroscopic Shoulder Surgery.
Arthroscopic subacromial decompression may cause substantial postoperative pain. We undertook a randomized controlled trial to examine whether adding dexmedetomidine to the local anesthetic in an interscalene brachial plexus block and subsequent patient-controlled interscalene analgesia (PCIA) regime improved postoperative pain scores, patient satisfaction, rescue analgesic requirement, and local anesthetic consumption. ⋯ Addition of dexmedetomidine to levobupivacaine for interscalene brachial plexus block decreases pain scores and increases patient satisfaction after arthroscopic subacromial decompression.

Randomized Controlled Trial
Pain reduction in myofascial pain syndrome by anodal transcranial direct current stimulation combined with standard treatment: a randomized controlled study.
Myofascial pain syndrome (MPS) in the shoulder is among the most prevalent pain problems in the middle-aged population worldwide. Evidence suggests that peripheral and central sensitization may play an important role in the development and maintenance of shoulder MPS. Given previous research supporting the potential efficacy of anodal transcranial direct current stimulation (tDCS) for modulating pain-related brain activity in individuals with refractory central pain, we hypothesized that anodal tDCS when applied over the primary motor cortex (M1) combined with standard treatment will be more effective for reducing pain in patients with MPS than standard treatment alone. ⋯ Five consecutive days of anodal tDCS over M1 combined with standard treatment appears to reduce pain intensity and may improve PROM, faster than standard treatment alone. Further tests on the efficacy and duration of effects of tDCS in the treatment of MPS are warranted.

Low Back Pain Patient Subgroups in Primary Care - Pain Characteristics, Psychosocial Determinants and Health Care Utilization.
In industrialized countries, low back pain (LBP) is one of the leading causes for prolonged sick leave, early retirement, and high health care costs. Providing the same treatments to all patients is neither effective nor feasible, and may impede patients' recovery. Recent studies have outlined the need for subgroup-specific treatment allocation. ⋯ Our study adds substantially to the knowledge of LBP-related case-mix in primary care. Information on differential health care needs may be inferred from our study, enabling decision makers to allocate resources more appropriately and to reduce costs.

Cognitive Mediators of Treatment Outcomes in Pediatric Functional Abdominal Pain.
Cognitive-behavioral (CB) interventions improve outcomes for many pediatric health conditions, but little is known about which mechanisms mediate these outcomes. The goal of this study was to identify whether changes in targeted process variables from baseline to 1 week posttreatment mediate improvement in outcomes in a randomized controlled trial of a brief CB intervention for idiopathic childhood abdominal pain. ⋯ Results suggest that reductions in reports of children's pain and GI symptoms after a social learning and CB intervention were mediated at least in part by decreasing maladaptive parent and child cognitions.
