Re-biopsy of the prostate using a stereotactic transperineal technique.

Purpose: In this study we investigated the detection rate and morbidity of stereotactic transperineal prostate re-biopsy with 3-dimensional mapping for diagnosis of nonpalpable isoechoic occult prostate malignancy.

Materials And Methods: A total of 180 consecutive patients with continued increasing total prostate specific antigen and at least 1 prior benign transrectal prostate biopsy underwent stereotactic transperineal prostate biopsy at a single outpatient institution between April 2004 and March 2006. Similar to a prostate brachytherapy procedure, patients were placed in the dorsal lithotomy position.

The efficacy of 500 CentiGray radiation in the prevention of heterotopic ossification after total hip arthroplasty: a prospective, randomized, pilot study.

A prospective, randomized, pilot study comparing 500 cGy (group A) versus 1,000 cGy (group B) radiation treatment for the prevention of heterotopic bone in a consecutive group of high-risk patients undergoing total hip arthroplasty was performed. Treatment was initiated within ninety-six hours and given in equal, divided doses: 2 doses for group A and 5 doses for group B. No statistically significant difference was found in the demographics between the 2 groups.
