Isolated corpus callosum agenesis: a ten-year follow-up after prenatal diagnosis (how are the children without corpus callosum at 10 years of age?).

Background: Corpus callosum agenesis (CCA) is generally diagnosed in utero. Outcome appears to be better if the malformation is isolated. The aim of this study, which is the first one with a long (10 years) and standardized follow up, was to report cognitive abilities of children with isolated CCA diagnosed prenatally.

Amniocentesis performed for karyotyping after identified ultrasonographic abnormalities: what to expect?

Objectives: The aim of this study was to evaluate the relative risk of identifying fetal chromosomal anomalies after finding ultrasonographic (US) abnormalities in a high-risk population who underwent amniocentesis.

Methods: A retrospective review of a cohort of patients with single pregnancies who underwent genetic amniocentesis was undertaken. Univariate and multivariate analysis were used to determine the best correlations between US findings and chromosomal abnormalities.

Maternal immune response and neonatal seroprotection from a single dose of a monovalent nonadjuvanted 2009 influenza A(H1N1) vaccine: a single-group trial.

Background: Pregnant women and infants who get influenza are at increased risk for severe illness.

Objective: To evaluate the immunogenicity and transplacental antibody transfer of 2009 pandemic influenza A(H1N1) vaccine administered during pregnancy.

Design: Prospective, multicenter, single-group clinical trial.

[Assessment of AFP in amniotic fluid: comparison of three automated techniques].

Ultrasound scanning is useful to detect neural tube defect (NTD) but scarcely distinguished between closed NTD and open NTD, which had very different prognosis. An amniotic fluid punction is thus mandatory to search for an increase in alpha foeto protein (AFP) levels and for the presence of acetylcholinesterase which identified open NTD. However, AFP levels fluctuate both with the gestational age and the assay used.

Fetopathologic examination for early termination of pregnancy: dogma or necessity?

Objective: Our objective was assessment of fetopathological examination after termination of pregnancy (TOP) for fetal anomalies with normal karyotype <17 weeks of gestation.

Study Design: This was a multicenter retrospective study. Records of TOP for fetal anomalies with normal karyotype were analyzed.

MRI of the fetal posterior fossa.

MRI is a useful tool to complement US for imaging of the fetal posterior fossa (PF). In France, the discovery of a PF malformation in the fetus frequently leads to termination of pregnancy (80% in a personal series). However, despite improved accuracy in the diagnosis of PF abnormalities, prognosis remains uncertain.

Agenesis of corpus callosum: prenatal diagnosis and prognosis.

Introduction: Agenesis of corpus callosum (ACC) is commonly diagnosed prenatally. When isolated, it appears to carry a good prognosis but studies are often retrospective and follow-up short. We report a prospective study of 17 children (11 boys, 6 girls) with prenatally diagnosed isolated ACC.
