Observational Study
Dexamethasone and Clonidine, but not Epinephrine, Prolong Duration of Ropivacaine Brachial Plexus Blocks, Cross-Sectional Analysis in Outpatient Surgery Setting.
The primary aim of this study is to determine the effect of adding dexamethasone, clonidine or both with and without epinephrine to ropivacaine and bupivacaine brachial plexus blocks. ⋯ For brachial plexus blocks, epinephrine did not affect the duration of analgesia when added to ropivacaine. Epinephrine did not enhance the observed increase of block duration induced by clonidine or the combination of clonidine and dexamethasone. The most block duration enhancement was observed when combination of clonidine and dexamethasone were added to ropivacaine.

To formulate timely evidence-based guidelines for the management of opioid-induced bowel dysfunction. ⋯ In recent years, more insight has been gained in the pathophysiology of this "entity"; new treatment approaches have been developed, but guidelines on clinical best practice are still lacking. Current knowledge is insufficient regarding management of the opioid side effects on the upper gastrointestinal tract, but recommendations can be derived from what we know at present.

Randomized Controlled Trial
Testing a Positive Psychological Intervention for Osteoarthritis.
Osteoarthritis is a leading cause of disability for which there is no cure. Psychosocial-oriented treatments are underexplored. We developed and tested an intervention to build positive psychological skills (e.g., gratitude) to reduce osteoarthritis symptom severity, including pain and functioning, and to improve psychosocial well-being in patients with knee or hip osteoarthritis. ⋯ The study successfully engaged patients with knee or hip osteoarthritis in a six-week intervention to build positive psychological skills. Improving osteoarthritis symptom severity and measures of psychosocial well-being, the intervention shows promise as a tool for chronic pain management.

Earlier studies suggest that pain extent, extracted from the patients' pain drawings, can help clinicians to identify people with central sensitization or worse clinical features. Our aim was to investigate possible associations between perceived pain extent and clinical pain features, burden of headache, psychological outcomes, and pressure sensitivity in people with chronic tension-type headache (CTTH). ⋯ Pain extent weakly correlated with older age as well as with higher emotional and physical burden of the headache in CTTH. In this population, there was no relationship between pain extent and PPT, indicating that larger pain areas were not associated with signs of central sensitization. Pain drawings can complement other clinical pain features for better characterization of CTTH, but further studies are needed.
