Isolated prostate specific antigen (PSA) determinations in asymptomatic individuals have not demonstrated sufficient sensitivity and specificity to be useful in the routine evaluation of prostate disease. To enhance the accuracy of serum PSA we have used a quotient of serum PSA and prostate volume, which we refer to as prostate specific antigen density(More)
Prostate specific antigen (PSA) is an extremely valuable tumor marker. However, its use in detection is limited by its low positive and negative predictive values. The ability of serum PSA to distinguish between benign and malignant prostatic conditions is particularly poor in the intermediate range of 4.1 and 10 ng./ml. by the Hybritech assay. We used(More)
We detail our experience with a monoclonal antibody to detect the cell surface P-glycoprotein product of the multidrug resistance gene (MDR-1) in the human bladder. A total of 32 patients had 44 different specimens analyzed. The samples consisted of 8 normal bladders, 21 transitional cell carcinomas, 1 mucinous adenocarcinoma, 3 P-0 bladder wall specimens(More)
OBJECTIVE To examine the efficacy of prostate-specific antigen (PSA) density (PSAD; serum PSA/prostate volume) as a predictor of clinical outcome of patients undergoing radical retropubic prostatectomy for clinically confined prostate cancer, and its ability to determine the presence of micrometastatic disease. METHODS A retrospective analysis of patient(More)
Acute pancreatitis during pregnancy is a rare event, and can be associated with high maternal mortality and fetal loss. Gallstone disease is thought to be the most common causative factor of acute pancreatitis, but, in many cases, the cause remains unclear. We report a case of a 36-year-old woman at 35 wk of gestation, who presented with severe pain(More)
Metastatic brain tumors from gastric cancer are extremely rare. A 61-year-old Korean woman, initially presenting with polydipsia and polyuria, was found to have metastatic lesions in the brain by MRI. We performed several diagnostic procedures to determine the origin of the brain metastases. She was revealed to have a soft tissue mass of the right adrenal(More)
KSTAR is an advanced tokamak with fully superconducting coils for the steady state research, which began in December 1995 and was completed in July 2008. As a single science project, it has been marked as the largest construction project in the history of Korea. During the construction period, we encountered several challenges, such as technical issues,(More)
Crohn's disease (CD) can involve any part of the gastrointestinal tract from the mouth to anus. However, gastroduodenal CD is rare with a frequency reported to range between 0.5% and 4.0%. Most patients with gastroduodenal CD have concomitant lesions in the terminal ileum or colon, but isolated gastroduodenal Crohn's disease is an extremely rare(More)
