Review Randomized Controlled Trial Comparative Study
Tolerance of local anesthetic for transrectal ultrasound-guided prostate biopsy: our experience and a literature review.
To determine whether local anesthetic injection or gel reduced pain during transrectal ultrasound-guided prostate biopsies and whether there was significant difference between quadrant and apex-only anesthesia. ⋯ There was significant pain reduction with local anesthetic injections but not with gel, and since there was no significant difference in efficacy between quadrant and apex-only injections, we recommend apex-only local anesthetic injections for transrectal ultrasound--guided prostate biopsies because it simplifies the injection procedure.

Randomized Controlled Trial Clinical Trial
Training module to teach ultrasound-guided breast biopsy skills to residents improves accuracy.
To evaluate the effectiveness of a training module in teaching residents the skills necessary to perform accurate and safe ultrasound-guided breast biopsies (USGBB). ⋯ Residents with training perform USGBBs more safely, and training significantly improves accuracy of USGBB in residents with no US experience. US experience improves biopsy success rates but does not affect safety levels of residents with no USGBB training.

Randomized Controlled Trial Comparative Study Clinical Trial
A prospective randomized clinical trial comparing two film-screen systems for chest radiography.
To compare conventional and asymmetric film-screen chest radiography systems in a prospective, randomized trial. ⋯ In general, the asymmetric system was superior for assessing mediastinal features and inferior for assessing the lateral subpleural zones in the posteroanterior radiographs. The asymmetric system was superior for assessing retrosternal lung markings and inferior for assessing fissures in the lateral radiographs. The results for the posteroanterior radiographs were consistent with the results of nonblinded studies reported elsewhere.
