Prenatal diagnosis of bilateral dacryocystocele using 3-D/4-D ultrasound technology: a case report.

Background: Bilateral dacryocystoceles develop as a result of obstruction of the nasolacrimal canal. The advances in obstetric sonography have led to increased diagnosis of this structural defect in the antenatal period as early as 24 weeks' gestation.

Case: We describe a case of bilateral dacryocystocele with clear visualization of this defect using 3-D/4-D sonography.

Clinical chorioamnionitis is not predicted by umbilical artery Doppler velocimetry in patients with premature rupture of membranes.

Chorioamnionitis substantially increases fetal and neonatal morbidity. Infants born to women with chorioamnionitis have a fourfold increase in neonatal morbidity. If this condition could be predicted before the clinical manifestation and thereby treated earlier, an improved perinatal outcome might reasonably be expected.

Prenatal ultrasonographic fetal iliac bone measurement. Correlation with gestational age.

The variety of circumstances under which ultrasound examinations are performed makes fetal iliac bone measurement an important indicator of gestational age. We studied 322 well-dated pregnancies from 13 to 40 weeks' gestation with sonogram measurements of the fetal iliac bone in order to examine the relationship between gestational age and bone length. The results indicate a linear relationship, as described by the equation iliac length = -0.

Crouzon syndrome: prenatal ultrasound diagnosis by binocular diameters.

This is a report of second-trimester prenatal diagnosis of Crouzon syndrome suggested by binocular and interorbital diameter measurement and family history. Early prenatal diagnosis provides the option of termination or optimal postnatal management for families who choose to continue the pregnancy.

Factors affecting perinatal mortality in an urban center.

In the Division of Obstetrics of the Statewide Perinatal Center, Newark, NJ, the rate of perinatal mortality fell from 51 in 1000, to 15 in 1000, between 1971 and 1986, and increased thereafter to 28 in 1000 by 1988. This development is analyzed against the background of changes in the environment and inside the Center. It is noted that during 2 study years (1983 and 1986) in our extremely high-risk patient population, the perinatal mortality rate was kept at, or under, the national average.
