Case Reports
CNS Measures of Pain Responses Pre- and Post-Anesthetic Ketamine in a Patient with Complex Regional Pain Syndrome.
Previous reports have indicated that ketamine anesthesia may produce significant improvement if not complete recovery of patients with complex regional pain syndrome (CRPS). ⋯ Future studies of brain function in these patients may provide novel insight into brain plasticity in response to this treatment for chronic pain.

To determine the direct and indirect effects of function on clinical variables such as age, pain intensity, years of the disease, severity of symptoms, and depression in women with electrodiagnostic and clinical diagnosis of carpal tunnel syndrome (CTS). ⋯ Our study demonstrated that function mediates the relationship between depression and symptoms severity with pain intensity in women with CTS. Future longitudinal studies will help to determine the clinical implications of these findings.

Controlled Clinical Trial
Pain Duration and Resolution following Surgery: An Inception Cohort Study.
Preoperative determinants of pain duration following surgery are poorly understood. We identified preoperative predictors of prolonged pain after surgery in a mixed surgical cohort. ⋯ Greater preoperative self-perceived risk of addiction, and lower anxiety sensitivity predicted a slower rate of pain resolution following surgery. Each of these factors was a better predictor of pain duration than preoperative depressive symptoms, post-traumatic stress disorder symptoms, past substance use, fear of pain, gender, age, preoperative pain, or preoperative opioid use.

Comparative Study
Shortening the Screener and Opioid Assessment for Patients with Pain-Revised (SOAPP-R): A Proof-of-Principle Study for Customized Computer-Based Testing.
The Screener and Opioid Assessment for Patients with Pain-Revised (SOAPP-R) is a 24-item self-report instrument that was developed to aid providers in predicting aberrant medication-related behaviors among chronic pain patients. Although the SOAPP-R has garnered widespread use, certain patients may be dissuaded from taking it because of its length. Administrative barriers associated with lengthy questionnaires further limit its utility. ⋯ Curtailment and stochastic curtailment have potential to improve the SOAPP-R's efficiency in computer-based administrations.

Review
An Expedited Diagnostic Algorithm for Lumbosacral Pain: "The Best Likelihood Scenario Approach".
The logic behind diagnostic blocks is very straightforward. What has not been determined is the way diagnostic blocks can be best used. ⋯ "The Best Likelihood Scenario" might improve diagnostic accuracy while decreasing societal costs.
