To determine which of several variables--age, serum level of prostate-specific antigen (PSA), findings of transrectal ultrasonography (TRUS) and findings of digital rectal examination (DRE)--are the best predictors of positive prostate biopsy results. ⋯ Men in whom there is a clinical concern for prostate cancer should undergo prostate biopsy if there is any elevation of age-specific PSA, particularly if the findings of TRUS are also abnormal. Because DRE alone was not predictive of biopsy outcome, algorithms for prostate cancer detection that rely on abnormal DRE results to identify men who should undergo biopsy will miss a significant number of cancers.

To assess the prevalence of high-attenuation mucous plugs observed on chest computed tomography (CT) scans in patients with allergic bronchopulmonary aspergillosis. ⋯ High-attenuation mucous plugs occur in approximately one quarter of patients with allergic bronchopulmonary aspergillosis and may be more common in patients with unilobar plugging.

To examine the effect of variations in anatomic features and operator experience on the success and complication rates of sonographically monitored cannulation of the internal jugular vein. ⋯ Real-time ultrasound monitoring is superior to blind techniques in cannulation of the internal jugular vein because of its ease, accuracy and safety. Sonographic real-time monitoring minimizes the impact of anatomic factors on success and complication rates. It is a safe and efficacious approach that should be preferred in the placement of central lines.
