Marietta Papadatou-Pastou, Maryanne Martin
The adequacy of three competing theories of hormonal effects on cerebral laterality are compared using functional transcranial Doppler sonography (fTCD). Thirty-three adult males participated in the study (21 left-handers). Cerebral lateralization was measured by fTCD using an extensively validated word generation task. Adult salivary testosterone (T) and cortisol (C) concentrations were measured by luminescence immunoassay and prenatal T exposure was indirectly estimated by the somatic marker of 2nd to 4th digit length ratio (2D:4D)...

We report the first series of five cases of prenatal diagnosis of pericallosal curvilinear lipoma (CL) and underline limitations and pitfalls in identifying a specific prenatal imaging pattern using ultrasound and MRI. On ultrasound, the main referring feature was a short corpus callosum in all cases. This subtle callosal dysgenesis was associated with a band of hyperechogenicity surrounding the corpus callosum, which can mimic the pericallosal sulcus, and increased in size over the third trimester in three out of four cases in which sonographic follow-up was obtained...

OBJECTIVE: Pallister-Killian syndrome (PKS) is a rare, sporadic genetic disorder caused by mosaic tetrasomy of the short arm of chromosome 12 (12p). Clinically, PKS is characterized by several systemic abnormalities, such as intellectual impairment, hearing loss, epilepsy, hypotonia, craniofacial dysmorphism, pigmentary skin anomalies, epilepsy, and a variety of congenital malformations. Prenatally, PKS can be suspected in the presence of ultrasound anomalies: diaphragmatic hernia, rhizomelic micromelia, hydrops fetalis, fetal overweight, ventriculomegaly in the central nervous system, congenital heart defects, or absent visualization of the stomach...

OBJECTIVE: Describe tools designed to predict preterm birth in asymptomatic high-risk pregnancy and determine their predictive value. METHODS: The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS: Obstetric history particularly spontaneous preterm birth identifies a population at risk for preterm birth for the current pregnancy (LE3). This risk is related to the number of prior preterm birth and is even higher than the term of the prior event is more premature and that the event concerns the last pregnancy (LE3)...

Introduction. Amniotic band syndrome and sequence are a relatively rare condition in which congenital anomalies occur as a result of the adherence and entrapment of fetal parts with coarse fibrous bands of the amniotic membrane. A large percentage of reported cases have an atypical gestational history. The frequency of this obstetric complication is not affected by fetal gender, genetic abnormality, or prenatal infection. Case. A 21-year-old, G1P0 female parturient at 18 weeks and 5 days with a single intrauterine gestation during a routine ultrasound evaluation was noted to have amniotic band sequence...
