Comparative Study
Complications of radiologically placed central venous ports and Hickman catheters in patients with AIDS.
To determine any differences in the complications following radiologic placement of 2 devices--Hickman catheters and central venous ports--to permit long-term central venous access in patients with AIDS. ⋯ Central venous ports are preferred over Hickman catheters for long-term central venous access in patients with AIDS.

Comparative Study
How Canadian radiologists adopt innovations: a survey.
Innovations and practice changes occur frequently in modern radiologic practice. In this study the authors sought to understand the process of adopting an innovation and to define the characteristics of some innovations and the effect of these characteristics on innovation adoption. ⋯ This study confirms a high rate of change in radiologic practice and documents the number and variety of learning resources used in the adoption of change. It is important for CME providers and educators to recognize the relatively low use of CME events in the process of change. Characterization of the innovations indicates concern with the clinical impact of the change and the individual physician's ability to accomplish the change within his or her practice.

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.
