Article Synopsis
  • - A 36-year-old pregnant woman at 16 weeks gestation exhibited severe hypertension with altered potassium, aldosterone, and renin levels, prompting the suspicion of primary aldosteronism and the consideration of surgery.
  • - An adrenal MRI revealed a left adrenal adenoma, but instead of surgery, she was treated conservatively with medications like labetalol and nifedipine, leading to no obstetric complications.
  • - After giving birth, her blood pressure remained high, but her hormonal levels stabilized; diagnosing and treating primary hyperaldosteronism during pregnancy is complex due to physiological changes and limited testing options.

Objective: The impact of resident involvement in the operating room for common procedures in obstetrics and gynaecology can shed light on the resource demands of teaching. The objective of this study was to quantify the increased surgical time associated with teaching obstetrics and gynaecology resident trainees across a range of procedures known to require surgical assistance.

Methods: This population-based retrospective cohort study compared surgical duration between academic (teaching) hospitals and community (non-teaching) hospitals.

Analysis of fetal adipose tissue volumes may provide useful insight towards assessment of overall fetal health, especially in cases with abnormal fetal growth. Here, we assess whether fetal adipose tissue volume can be reliably measured using 3D water-fat MRI, using a quantitative assessment of the lipid content of tissues. Seventeen women with singleton pregnancies underwent a fetal MRI and water-only and fat-only images were acquired (modified 2-point Dixon technique).

Objective: This study was undertaken to determine the relationship of umbilical cord pH and base excess (BE) values to adverse neonatal outcomes for a large tertiary hospital population delivering at term. Study design The perinatal/neonatal database of St. Joseph's Health Care, London, Canada, was used to obtain the umbilical cord pH and BE values, incidence of adverse neonatal outcomes, and patient demographics for all term (>/=37 weeks' gestation), singleton, liveborn infants with no major anomalies delivering between November 1995 and March 2002 (n=20,456).

Objective: This study was undertaken to determine the ability of intrapartum electronic fetal heart rate monitoring (EFM) plus fetal electrocardiogram (ECG) ST segment automated ANalysis (STAN, Neoventa Medical, Goteborg, Sweden) monitoring to predict metabolic acidemia (defined as an umbilical cord artery pH < 7.15 and base deficit > or = 12 mmol/L) at birth.

Study Design: Women with singleton, term pregnancies who had a clinical indication for internal EFM with a fetal scalp electrode were included in the study.

Objective: Our purpose was to determine the relationship/predictive value of umbilical cord pH and base excess (BE) values to adverse neonatal outcomes for preterm infants.

Study Design: A tertiary center perinatal/neonatal database was used to obtain umbilical cord pH and BE values, adverse neonatal outcomes, and patient demographics for preterm (PT, 32-36 weeks gestational age) and very preterm (VPT, 25-32 weeks gestational age) singleton live-born infants delivered between November 1995 and March 2002.

Results: PT (n=1807) and VPT (n=603) groups demonstrated a significant inverse curvilinear relationship of umbilical cord pH and BE values to Apgar score <7 at 5 minutes, respiratory distress syndrome, assisted ventilation, and intraventricular hemorrhage/periventricular leukomalacia.

Objectives: To determine senior medical students' exposure to lectures and clinical experiences on emergency contraception (EC).

Methods: Ninety third-year medical students at the University of Western Ontario (UWO) were surveyed at the end of a year of clinical clerkship. The survey assessed exposure to contraception, EC, and other reproductive health experiences over the preceding 3 years of medical training, as well as personal opinions about the availability of family planning services.
