Review Meta Analysis
Effects of Combining Dexmedetomidine and Opioids for Postoperative Intravenous Patient-controlled Analgesia: A Systematic Review and Meta-analysis.
This meta-analysis evaluated the effects of opioid-dexmedetomidine (DEX) combinations for postoperative patient-controlled analgesia (PCA). ⋯ These data suggest that an opioid-DEX combination is a safe and effective strategy for postoperative intravenous PCA.

To determine the specific factors that affect Internet headache diary compliance among youth with primary headaches. ⋯ Specific factors predict Internet-based headache diary compliance. Further research about the factors related to diary compliance and the optimization of diary-based data collection is warranted.

To test the hypothesized associations between measures of the behavioral inhibition system (BIS) and behavioral activation system (BAS) and both the intensity and frequency of pain. ⋯ The findings are consistent with predictions based on a model hypothesizing that pain has a nonlinear impact on both BIS and BAS, with a stronger impact on BIS than BAS. If the current results are replicated in other samples, including samples of individuals with chronic pain, they have important implications for identifying biological factors that could influence pain and behavioral responses to pain, as well as for the development and evaluation of treatments that could enhance positive treatment outcomes.

Randomized Controlled Trial
Evaluation of Efficacy of Bone Scan With SPECT/CT in the Management of Low Back Pain: A Study Supported by Differential Diagnostic Local Anesthetic Blocks.
Conventional radiologic modalities provide details only about the anatomic aspect of the various structures of the spine. Frequently the structures that show abnormal morphology may not be the cause of low back pain (LBP). Functional imaging in the form of bone scan along with single photon emission computerized tomography (SPECT/CT) may be helpful in identifying structures causing pain, whether morphologically normal or not. The objective of this study is to evaluate the role of bone scan with SPECT/CT in management of patients with LBP. ⋯ Bone scan with SPECT/CT was found to complement the clinical workup of patients with LBP. Inclusion of bone scan with SPECT/CT in LBP management protocol can help in making a correct diagnosis. At times it might bring out some new information that may be vital for further management of the patients with LBP.

The prevalence of knee osteoarthritis (OA) is increasing with the aging population and is exacerbated by the growing numbers of obese older adults. Low levels of vitamin D, measured by serum 25-hydroxyvitamin D (25(OH)D), in older adults and obese individuals are correlated with several negative health conditions, including chronic pain. This cross-sectional study sought to examine the interactive influence of 25(OH)D levels and obesity on knee OA pain and functional performance measures. ⋯ The mechanisms by which adequate 25(OH)D levels are associated with pain severity and improved function have not been completely elucidated. It may be that the pleiotropic role of biologically active 25(OH)D influences pain and pain processing through peripheral and central mechanisms. Alternatively, higher levels of pain may lead to reduced outdoor activity, which may contribute to both obesity and decreased vitamin D. Thus, investigating vitamin D status in obese and nonobese individuals with knee OA warrants further study.
