An ultrasound approach was developed to identify normal amniotic fluid volume. The uterine cavity was divided into four quadrants. With the use of linear-array, real-time B-scanning, the vertical diameter of the largest pocket in each quadrant was measured. The sum of these four quadrants was used to provide a single number for the amniotic fluid volume and(More)
Amniotic fluid volume assessment using a semiquantitative four-quadrant technique, the amniotic fluid index, was evaluated in relationship to fetal heart rate (FHR) testing and perinatal morbidity in 330 high-risk pregnancies. An inverse relationship was found between the amniotic fluid index and nonreactive nonstress tests (NST), FHR decelerations,(More)
Amniotic fluid volume assessment has become an important part of antepartum fetal surveillance. The amniotic fluid index (AFI), or four-quadrant technique, has been suggested for this purpose. While previous reports have outlined this technique and correlated the results with pregnancy outcome, none have reviewed the changes in AFI throughout pregnancy. We(More)
PURPOSE Prostate cancer in men age 50 years or younger traditionally has accounted for approximately 1% of those diagnosed with prostate cancer. Prior studies of prostate cancer in men of this age led many clinicians to believe that they have a less favorable outcome than older men. Most of these studies were conducted before the advent of prostate specific(More)
Intrauterine infection with Candida albicans is a rare occurrence in pregnancy. We report the association of an intrauterine contraceptive device with such an infection in an asymptomatic patient. This infection, discovered incidentally at the time of genetic amniocentesis for advanced maternal age, resulted in a spontaneous abortion at 18 weeks' gestation.
The complex mechanisms responsible for fetal hearing are in place and functional by 26 weeks of gestation, but little is known about the acoustic milieu of the amniotic cavity. We placed an electrically isolated microphone in the uterus of nine term gravid volunteers after amniorrhexis. Baseline levels of intrauterine sound were 72 to 88 db. Transabdominal(More)
The purpose of this study was to quantify the metabolic demand of simulated shipboard fire-fighting procedures currently practised by men and women in the Royal Navy (RN) and to identify a minimum level of cardiovascular fitness commensurate with satisfactory performance. Thirty-four males (M) and 15 females (F) volunteered as subjects for this study(More)
Antepartum fetal heart rate testing, specifically the nonstress test, is of accepted value in the antenatal surveillance of high-risk pregnancies. Fetal rest-activity cycles coupled with arbitrary test intervals appear to lead to falsely nonreactive tests. Methods to alter fetal behavioral states have not been uniformly successful. A retrospective analysis(More)
A greater awareness of the advantages and limitations of new methods of administering postcesarean analgesia would help the obstetrician care for the recovering patient. Patient-controlled analgesia and epidural morphine are two new modalities for postoperative pain relief. The purpose of this prospective investigation was to compare their effectiveness,(More)
Preliminary observations have shown that fentanyl citrate, a potent narcotic, is helpful during labor without undue side effects. This randomized prospective investigation compared the patient-controlled administration of fentanyl with that of administration by nurses on request. Eighty healthy women beginning active labor (cervical dilation 4 cm) at term(More)
