Randomized Controlled Trial Comparative Study
Liver cancer: effects, safety, and cost-effectiveness of controlled-release oxycodone for pain control after TACE.
To evaluate the analgesic effect, safety, and cost-effectiveness of controlled-release oxycodone (CRO) to control postoperative pain in patients with liver cancer who are undergoing transarterial chemoembolization. ⋯ CRO is effective, safe, and cost-effective in the control of postoperative pain after transarterial chemoembolization for patients with inoperable liver cancer.

An international working group has modified the Atlanta classification for acute pancreatitis to update the terminology and provide simple functional clinical and morphologic classifications. The modifications (a) address the clinical course and severity of disease, (b) divide acute pancreatitis into interstitial edematous pancreatitis and necrotizing pancreatitis, (c) distinguish an early phase (1st week) and a late phase (after the 1st week), and (d) emphasize systemic inflammatory response syndrome and multisystem organ failure. In the 1st week, only clinical parameters are important for treatment planning. ⋯ All can be sterile or infected. Terms such as pancreatic abscess and intrapancreatic pseudocyst have been abandoned. The goal is for radiologists, gastroenterologists, surgeons, and pathologists to use the revised classifications to standardize imaging terminology to facilitate treatment planning and enable precise comparison of results among different departments and institutions.

To evaluate the effect of incorporating radiation risk into microsimulation (first-order Monte Carlo) models for breast and lung cancer screening to illustrate effects of including radiation risk on patient outcome projections. ⋯ Because including radiation exposure risk can influence long-term projections from simulation models, it is important to include these risks when conducting modeling-based assessments of diagnostic imaging.

To retrospectively examine the association between the inclusion of epidemiologic information in lumbar spine magnetic resonance (MR) imaging reports regarding findings in asymptomatic individuals and the rates of subsequent cross-sectional imaging and treatments in patients with low back pain or radiculopathy referred for imaging by primary care providers. ⋯ Patients were less likely to receive narcotics prescriptions from primary care providers when epidemiologic information was included in their lumbar spine MR imaging reports.

Comparative Study
Comparison of three-dimensional isotropic T1-weighted fast spin-echo MR arthrography with two-dimensional MR arthrography of the shoulder.
To determine the accuracy of a three-dimensional (3D) isotropic T1-weighted fast spin-echo (FSE) magnetic resonance (MR) sequence as compared with a conventional two-dimensional (2D) sequence in the diagnosis of rotator cuff tears and labral lesions. ⋯ The accuracy of 3D isotropic FSE MR arthrography may be comparable with that of conventional 2D MR arthrography in the diagnosis of rotator cuff tears and labral lesions with a shorter imaging time.
