Male-to-female gender ratio in fetuses with increased nuchal translucency.

Objective: To describe gender distribution in fetuses with increased nuchal translucency (NT) measurements.

Methods: All fetuses with mild (2.5-2.

First-trimester crown-rump length as a predictor of fetal LGA and SGA at term.

Objective: To determine whether first-trimester crown-rump length (CRL) is associated with birthweight extremes at term.

Methods: Included in this study were all term, small for gestational age (SGA), and large for gestational age (LGA) neonates with no other obstetric complications and no abnormal outcomes of pregnancy. CRL at 12.

Effects of the individual uterine contraction on fetal head descent and cervical dilatation during the active stage of labor.

Objective: To evaluate the effects of individual uterine contractions on instantaneous values of cervical dilatation and head station along the active stage of labor.

Study Design: Cervix dilatation and fetal head station were measured continuously using a labor monitor that is based on ultrasonic triangulation. The relations between the two variables in response to each contraction were analyzed.

Massive luteinized follicular cyst of pregnancy.

Background: A large luteinized follicular cyst can rupture or twist during pregnancy. However, in the absence of those complications a simple ovarian cyst can often be managed conservatively, provided that sonographic evaluation of the cyst is benign. Rapid growth of a simple follicular cyst is rare but may occasionally complicate pregnancy.

Live three-dimensional echocardiography of the human fetus.

The purpose of this study was to investigate the feasibility of using a new three-dimensional ultrasound system to perform fetal echocardiographic examination in real time. The device consisted of a Philips Sonos 7500 (Andover, MA) ultrasound system and a 4 MHz, 4X matrix transducer. The study was approved by the Institutional Review Board and was performed with the informed consent of the mother.
