From 1995 through 1997, clubfoot was detected by transabdominal sonography in 13 fetuses of 12 women, in nine bilaterally and in four unilaterally (total, 22 clubfeet). The average menstrual age at diagnosis was 23.6 weeks (range, 17-36). Three fetuses had associated malformations: two were therapeutically aborted and one died 2 ...

The prospect of fetal surgery for cleft lip is predicated on our ability to accurately identify fetuses with clefts and exclude those that have associated anomalies. Prenatal ultrasound is currently the most appropriate means with which to do this. We reviewed the ultrasonographic data from two large perinatal referral institutions ...

We determined the feasibility of prenatal prediction of type 1 homozygous alpha-thalassemia at 12 to 13 weeks of gestation by either abdominal or vaginal (or both) ultrasonographic examination to measure the fetal cardiothoracic ratio in 135 at-risk pregnancies. Forty-three fetuses were affected by homozygous type 1 alpha-thalassemia. The mean cardiothoracic ...

The objective of this paper is to study the possible additive effect of corticosteroids to the known effect of indomethacin on potency of the human ductus arteriosus. Systolic and diastolic blood flow of the fetal ductus arteriosus was measured by echo Doppler at 26-32 weeks of gestation. Four groups of ...
Fukumasu Y - - 1999
The small neutrophil reserve and exaggerated release of stored neutrophils are factors which predispose neonates to neutrophil reserve exhaustion during bacterial sepsis. Our objective is to try to improve in utero the myelopoietic function of the fetus before delivery. In the first series, recombinant human (rh) granulocyte colony-stimulating factor (G-CSF) ...
Delgado-Baeza E - - 1999
The purpose of this assay was to study the hindfoot patho-dynamic in clubfoot-like deformity during fetal development. Experimental induction of clubfoot-like deformity in rat fetuses was produced by maternal administration of retinoic acid (120 mg/kg body weight) as a single intragastric dose on day 10 of pregnancy. Hindlimbs from fetuses ...

We studied how chaotic and periodic heart rate dynamics differ between normal fetuses (n = 192) and uncomplicated intrauterine growth restricted fetuses (n = 86), aged 31-42 weeks of gestation. We analyzed each fetal heart rate time series for 25 min. We quantified the chaotic dynamics of each fetal heart ...
Lelièvre-Pégorier M - - 1998
Vitamin A plays a critical role in fetal organogenesis, and its severe deficiency during pregnancy is known to result in malformations of several organs, including the kidney. However, the consequences of mild vitamin A deficiency (VAD) has received little attention. In the present study, we examined the effect of in ...

To elucidate the mechanisms that facilitate tolerance at the maternal-fetal interface, we are investigating the role of genes that are involved in peripheral self-tolerance in couples with idiopathic recurrent miscarriage. CTLA-4 is a negative regulator of T-cell proliferation and has been associated with human autoimmune disease. An AT(n) polymorphism in ...

Twenty-one fetuses with an enlarged fourth ventricle were detected by ultrasound at 14-16 weeks' gestation. No other central nervous system anomalies were observed and a normal size fourth ventricle was noted in all cases on follow-up scans at 22-23 weeks' gestation. Five fetuses had associated structural anomalies: a single umbilical ...

After more than 20 years of using ultrasound to examine the fetal head, there are still areas of controversy. The size of the ventricular atrium or the anteroposterior measurement of the posterior fossa have been shown to be relatively stable throughout pregnancy. However, there are instances in which intracranial malformations ...

Ultrasonographic examination of the fetal abdomen is an integral part in all routine fetal sonograms and can provide significant information about the status and prognosis of the fetus. Although many types of fetal anomalies can be identified (i.e., gastroschisis, omphalocele, or congenital diaphragmatic hernia), there are several sonographic findings that ...

A retrospective study was performed over a 5-year period (1990-94) to evaluate the effectiveness of prenatal ultrasonography in terms of sensitivity, specificity, and predictive values in detecting fetal anomalies by comparing prenatal ultrasonic results with anomalies found in neonates and the perinatal outcome of anomalous fetuses. Minor congenital anomalies as ...

The experiment was conducted on 36 swine fetuses divided into the three developmental groups described by Marrable (1971). In the postdiaphragmatic part, 10 to 20 primary ganglia were found in the sympathetic trunk. They had fused with the secondary structures, and hence the sympathetic trunks studied finally consisted of 6-16 ...

Smith-Lemli-Opitz syndrome (SLOS) in human infants is a common autosomal recessive malformation syndrome (estimated incidence, 1:20,000). It is characterized clinically by congenital anomalies, especially craniofacial and limb defects, and biochemically by a defect in 7-dehydrocholesterol-delta7-reductase activity (7DHC-reductase), the final enzyme in cholesterol biosynthesis. In previous studies, early administration of the ...

Clinical evidence has linked intrauterine compromise such as fetal hypoxemia to poor neurologic outcome in the newborn. In this study we examined the effects of inducing chronic fetal hypoxemia by impairment of placental function on brain development in fetal sheep. Placental insufficiency was induced from 120 to 140 d of ...

We applied microsatellite analysis to prenatal diagnosis of Fukuyama-type congenital muscular dystrophy (FCMD), an autosomal recessive severe muscular dystrophy associated with brain malformations. Recent identification of the FCMD gene locus at 9q31-q33 provided the basis for prenatal diagnosis and carrier detection. We recently developed new microsatellite markers which are closer ...
