Observational Study
Microstructural Abnormalities in Gray Matter of Patients with Postherpetic Neuralgia: A Diffusional Kurtosis Imaging Study.
Changes in functional activity and connectivity have been shown in patients experiencing postherpetic neuralgia (PHN) pain. However, PHN-induced structural changes, particularly in the gray matter of which volume and density was widely reported to be altered by other chronic pain, have not been well characterized. ⋯ Postherpetic neuralgia, diffusional kurtosis imaging, insula cortex, gray matter, voxel-based analysis.

Randomized Controlled Trial
Buprenorphine, Clonidine, Dexamethasone, and Ropivacaine for Interscalene Nerve Blockade: A Prospective, Randomized, Blinded, Ropivacaine Dose-Response Study.
This study investigated interscalene block for shoulder arthroplasty with various ropivacaine concentrations in the presence of clonidine, dexamethasone, and buprenorphine. The goal was prolonged analgesia with minimal motor blockade. ⋯ For maximum pain reduction, combining perineural additives with ropivacaine 0.375% or 0.2% is suggested. To minimize motor blockade, perineural additives can be combined with ropivacaine, 0.1%.

Chronic pelvic pain (CPP) is a high burden for patients and society. It affects 15-24% of women in reproductive age and is an area of high unmet medical need. CPP can be caused by a wide range of visceral diseases such as abdominal infections, gastrointestinal or gynaecological diseases like endometriosis. Despite the high medical need for this condition, pharmacological approaches are hampered by the limited number of available methods for the behavioural evaluation of pain in inflammation-driven animal models of pelvic pain. ⋯ This study described for the first time the use of DWB as a non-subjective and non-reflexive method for the evaluation of inflammatory-driven abdominal pain in a mouse model.

Validation of the Critical Care Pain Observation Tool in Critically Ill Patients With Delirium: A Prospective Cohort Study.
The 2013 clinical practice guidelines for the management of pain, agitation, and delirium in adult patients in the ICU suggest that pain be routinely assessed using a validated pain assessment tool. Currently available tools have only been evaluated in nondelirious critically ill patients, yet delirium can affect as many as 80% of ICU patients. The validated pain assessment tool adopted by our institution is the Critical Care Pain Observation Tool, and the objective of this study was to investigate the validity of this tool in patients with evidence of delirium. ⋯ The Critical Care Pain Observation Tool is a valid pain assessment tool in noncomatose, delirious adult ICU patients who are unable to reliably self-report the presence or absence of pain.

Disparities in health care associated with patients' gender, race, and age are well documented. Previous studies using virtual human (VH) technology have demonstrated that provider characteristics may play an important role in pain management decisions. However, these studies have largely emphasized group differences. ⋯ These findings highlight the interaction of patient and provider factors in driving clinical decision making. Although profession was related to use of VH age cues in pain-related clinical judgments, this relationship was modified by providers' personal characteristics. Additional research is needed to understand what aspects of professional training or practice may account for differences between physicians and dentists and what forms of continuing education may help to mitigate the disparities.
