Meta Analysis
Specific Safety Profile of Bevacizumab in Asian Patients With Advanced NSCLC: A Meta-Analysis.
Randomized studies have obtained varying findings regarding the benefits and toxicities of bevacizumab in the treatment of nonsmall cell lung cancer (NSCLC). It is unclear whether the discrepancies among trials are due to ethnic/racial differences. We therefore performed a meta-analysis of all published, randomized, controlled clinical trials involving bevacizumab in patients with NSCLC to assess its effectiveness and safety in Asian and non-Asian populations. ⋯ The rates of severe bleeding (relative risk [RR], 2.17; P = 0.02) and thromboembolism (RR, 3.65; P < 0.0001) were significantly higher, while the rate of severe proteinuria was significantly lower (RR, 0.43; P < 0.0001), in non-Asian than in Asian populations. The rates of severe hypertension (P = 0.71) and hemoptysis (P = 0.66) were similar in Asian and non-Asian populations. Bevacizumab combined with chemotherapy for first-line NSCLC treatment showed similar benefits in Asian and non-Asian populations, but had specific safety profiles in each.

Review Case Reports
High 18F-Fluorodeoxyglucose Uptake in Adrenal Angiomyolipoma: Case Report and Review of Literature.
Adrenal angiomyolipoma is an extremely rare tumor, although computed tomography (CT) or magnetic resonance imaging findings of adrenal angiomyolipoma have been reported, there are no reports regarding integrated fluorine-18-fluorodeoxyglucose positron emission tomography and computed tomography ((18)F-FDG PET/CT) imaging. We report a case of adrenal angiomyolipoma showing a significantly high uptake of (18)F-fluorodeoxyglucose on PET/CT study. ⋯ Adrenal angiomyolipoma can show an intense uptake in FDG-PET/CT, and this can easily be confused with a malignant disease. Adrenal angiomyolipoma should be considered as one of the differential diagnoses in cases of adrenal incidentaloma with intense FDG uptake.

The aim of this retrospective study was to compare accuracies of axial, multiplanar, and volume-rendered 3-dimensional (3D) images in the diagnosis of costal bone lesions. Forty-one patients, aged from 10 to 72-years old, with costal bone lesions underwent multidetector CT (MDCT). Axial, multiplanar, and 3D-volume-rendered images were reviewed by 3 reviewers for the property of the lesions (fracture, tumor, and tumor-like lesions or inflammation). ⋯ For the diagnosis of inflammation lesions, average accuracy was 100% for all the 3 image formats. Interobserver agreement independence of imaging formats was high. Multiplanar and 3D-volume-rendered images were superior to axial images in diagnosis of fracture, tumor, and tumor-like lesions; however, for the evaluation of inflammation lesions, there were no difference by 3 image formats.

This cross-sectional study sought to identify dimensions underlying measures of impairment, disability, personal factors, and health status in patients with cervical radiculopathy. One hundred twenty-four patients with magnetic resonance imaging-verified cervical radiculopathy, attending a neurosurgery clinic in Sweden, participated. Data from clinical tests and questionnaires on disability, personal factors, and health status were used in a principal-component analysis (PCA) with oblique rotation. ⋯ The third component including anxiety, depression, and catastrophizing explained 7.6%. The strongest-loading variables of each dimension were "present neck pain intensity," "fear avoidance," and "anxiety." The three underlying dimensions identified and labeled Pain and functioning, Health, beliefs, and kinesiophobia, and Mood state and catastrophizing captured aspects of importance for cervical radiculopathy. Since the variables "present neck pain intensity," "fear avoidance," and "anxiety" had the strongest loading in each of the three dimensions; it may be important to include them in a reduced multidimensional measurement set in cervical radiculopathy.

Observational Study
A Cohort Study of Decompressive Craniectomy for Malignant Middle Cerebral Artery Infarction: A Real-World Experience in Clinical Practice.
Decompressive hemicraniectomy with malignant middle cerebral artery (MCA) infarction is effective but remains underutilized. The aim of this study was to observe the utilization of this intervention in mainland China. We included patients with malignant MCA infarction who admitted in West China Hospital between December 2007 to March 2011. ⋯ After adjusting for confounders including age, sex, NIHSS score, and GCS score on admission, decompressive hemicraniectomy was an independent predictor of good outcome for 1 year (OR = 3.44, 95% CI, 1.27-9.31). This study shows better outcomes in the surgical group, which are consistent with findings in previous prospective randomized trials. However, this beneficial intervention remains underutilized in clinical settings.
