Purpose: We evaluated the utility of 10-, 12-, and 16-core prostate biopsies for detectingprostate cancer (PCa) and correlated the results with prostate-specific antigen (PSA)levels, prostate volumes, Gleason scores, and detection rates of high-grade prostaticintraepithelial neoplasia (HGPIN) and atypical small acinar proliferation (ASAP). Materials and Methods: A prospective controlled study was conducted in 354 consecutivepatients with various indications for prostate biopsy. Sixteen-core biopsy specimenswere obtained from 351 patients. The first 10-core biopsy specimens were obtainedbilaterally from the base, middle third, apex, medial, and latero-lateral regions. Afterward, six additional punctures were performed bilaterally in the areas more lateralto the base, middle third, and apex regions, yielding a total of 16-core biopsyspecimens. The detection rate of carcinoma in the initial 10-core specimens was comparedwith that in the 12- and 16-core specimens. Results: No significant differences in the cancer detection rate were found between thethree biopsy protocols. PCa was found in 102 patients (29.06%) using the 10-core protocol,in 99 patients (28.21%) using the 12-core protocol, and in 107 patients (30.48%) usingthe 16-core protocol (p=0.798). The 10-, 12-, and 16-core protocols were comparedwith stratified PSA levels, stratified prostate volumes, Gleason scores, and detectionrates of HGPIN and ASAP; no significant differences were found. Conclusions: Cancer positivity with the 10-core protocol was not significantly differentfrom that with the 12- and 16-core protocols, which indicates that the 10-core protocolis acceptable for performing a first biopsy.

We reported clinical and physical responses to 7 weeks of anabolic-androgenic steroid (AAS) self-administration in a male recreational bodybuilder. He was self-administrating a total of 3,250 mg of testosterone when his previous and current clinical and physical trials records were revisited. Body shape, performance, and biochemistry results were clustered into three phases labeled PRE (before the self-use), POST I (immediately at the cessation of the 7-week administration), and POST II (12 weeks after the cessation). Elevated testosterone and estradiol levels were observed in the POST I phase, while hepatic and renal functions remained altered in the POST II phase. Body mass and body fat percentages increased throughout the three phases. When adjusted according to body mass, drops in aerobic and anaerobic power and capacity (2.1% to 12.9%) were observed across the phases. This case report shows that overall performance decreased when a bodybuilding practitioner self-administered AAS.
