Diagnostic performance of PCA3 to detect prostate cancer in men with increased prostate specific antigen: a prospective study of 1,962 cases.

Purpose: The detection of prostate cancer relies primarily on abnormal digital rectal examination or increased serum prostate specific antigen concentration. However, low positive predictive values result in many men with increased prostate specific antigen and/or suspicious digital rectal examination having a negative biopsy. We investigated the value of the PCA3 (prostate cancer gene 3) urine test in predicting the likelihood of diagnosis of cancer before biopsy.

Female pseudohermaphroditism in a neonate born to a mother with polycystic ovarian disease.

A newborn with female pseudohermaphroditism (profound masculinization of the external genitalia and preservation of the internal female genitalia) is presented. During pregnancy progressive hirsutism was noted in the mother, and polycystic ovaries were found at cesarean section. The serum testosterone level in the cord blood was elevated markedly (1,232 ng.
