The influence of MR imaging on changes in patient counseling in obstetric patients with suspected fetal anomalies by ultrasound.

Objective: To determine the frequency of additional information provided by magnetic resonance (MR) imaging in supplement to ultrasound (US) in patients with fetal anomaly and to determine the influence of MR imaging findings on patient counseling.

Material And Method: MR imaging offetus was performed in 26 patients who have abnormal ultrasound results. Referring obstetricians were asked about how the additional information provided by MR imaging have effect on their decision marking, patient counseling, and case management.

Effectiveness of the model for prenatal control of severe thalassemia.

Objective: The aim of the research was to determine effectiveness of the model for prenatal control in reducing new cases of severe thalassemia.

Methods: Pregnant women at six tertiary centers were recruited to follow the model, consisting of (1) carrier screening using mean corpuscular volume (for alpha-thal-1 and beta-thal) and CMU-E screen (for HbE trait), (2) carrier diagnosis, (3) the couples at risk were counseled and offered prenatal diagnosis, and (4) termination of affected pregnancy. All neonates were evaluated for thalassemia.

Material And Method: A retrospective cohort study was conducted on singleton Southeast Asian immigrant pregnant women in Thailand between January 2007 and December 2008.

Results: One thousand two hundred sixty immigrant pregnant women and 5040 controls were included.

Doppler waveform indices of the Middle Cerebral Artery of normal fetuses in the first half of pregnancy in the Thai population.

Objective: To establish the reference ranges of middle cerebral artery (MCA) Doppler indices including pulsatility index (PI), resistance index (RI) and peak systolic velocity (PSV) of the Thai fetuses at gestational age of 11-20 weeks.

Methods: A descriptive cross-sectional study was conducted at Department of Obstetrics and Gynecology, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand. Normal singleton pregnancies between 11 and 20 weeks of gestation were recruited into the study for measurements of MCA Doppler indices between November 2005 and August 2006.

Study Design: Descriptive study.

Material And Method: One hundred and sixteen asymptomatic non-anemic pregnant women with an indication for cordocentesis at 18-22 weeks of gestation between January and June 2004 were recruited.
