PURPOSE We assessed the accuracy of MR imaging in differentiating between cancer and other prostatic disorders, and evaluated the diagnostic criteria for various prostatic diseases. MATERIAL AND METHODS A total of 74 endorectal coil MR studies were performed on 72 patients. Twenty patients had prostatic cancer, 20 benign prostatic hyperplasia (BPH), 4(More)
BACKGROUND The epidural stimulation test to confirm epidural catheter position has been described as being simple, fast, and reliable. We evaluated the feasibility of the epidural stimulation test and its potential in contributing to effective postoperative continuous epidural analgesia. METHODS Thirty adult patients (ASA I-III) undergoing major abdominal(More)
468 placentas were studied microscopically and by gross examination. Velamentous insertion of the umbilical cord, placenta circumvallate, retroplacental hematoma in connection with ablation of the placenta, and cord prolapse were found to be causative factors in asphyxia of the newborn. The increased placental weight was characteristic in maternal diabetes,(More)
PURPOSE To assess the quantity and frequency of hemorrhage after prostatic biopsy. As post-biopsy blood products may interfere with interpretation of MR images, we also investigated the optimal timing for MR examination after biopsy. MATERIAL AND METHODS Fifteen patients scheduled for prostatic biopsies were imaged with endorectal MR before and after the(More)
The aim of this study was to develop an endorectal MRI strategy for prostatic cancer. We evaluated the MR images from 44 consecutive prostatic cancer patients treated by radical prostatectomy. Each sequence from every examination was assessed separately with a specific tumor map drawn. Tumor localization, capsular penetration, and seminal vesicle invasion(More)
To evaluate the incidence of neonatal complications among infants exposed to indomethacin antenatally, postnatally or both ante-and postnatally (combined), the records of 240 infants of gestational ages between 23 to 32 weeks were analysed retrospectively. Antenatal indomethacin treatment for longer than 2 days with a daily or cumulative dosage ≥150 mg(More)
PURPOSE We assess the accuracy of endorectal coil magnetic resonance imaging (MRI) for detecting tumor localization, capsular penetration and seminal vesicle invasion in clinically organ confined prostate cancer. We also evaluate intra-observer and interobserver agreement in interpreting MRI studies. MATERIALS AND METHODS MRI studies of 51 consecutive(More)
BACKGROUND Both Gleason score and prostate-specific antigen (PSA) concentration are prognostic factors for prostate cancer. We assessed our ability to localize cancer lesions based on Gleason scores and PSA values by endorectal coil magnetic resonance imaging (MRI). We also evaluated whether the size of the prostate affects tumor detectability. METHODS We(More)
Many complications of prematurity have been suggested to result from free radical generation and an inadequacy of antioxidative capacity. We measured the plasma total peroxyl radical-trapping capability (TRAP) and concentrations of the main chain-breaking antioxidants contributing to it, i.e. uric acid, ascorbic acid, alpha-tocopherol, protein sulfhydryl(More)
