OBJECTIVE To investigate the prognostic factors for primitive fetal hydrothorax (PFHT) and propose a clinical strategy based on systematic literature review. METHODS We reviewed 64 articles describing 204 cases of PFHT. For each case we focused on 11 criteria. We investigated prognostic factors in the 89 cases where no in utero treatment was undertaken.(More)
We report on a case of true prenatal mosaic trisomy 13 on amniotic fluid associated with a normal phenotype at the age of 6 years. The amniocentesis was performed because of advanced maternal age and was controlled by a second sample. Morphological and cardiac ultrasonography did not reveal any fetal malformations. No trisomic cells were found in the fetal(More)
Homocysteine results from the demethylation of the essential amino acid methionine. Its metabolism depends primarily on three enzymes and several vitamin cofactors (vit. B6, B9 and B12). Genetic abnormality in these enzymes or deficiency of these vitamins lead to Hyperhomocysteinemia. Hyperhomocysteinemia belongs among the congenital thrombophilies and is a(More)
We report here on a familial case of centromeric heteromorphism of chromosome 18 detected by prenatal interphase fluorescence in situ hybridization (FISH) analysis transmitted by the mother to her fetus, and resulting in complete loss of one 18 signal. The prenatal diagnosis was performed by interphase FISH (AneuVysion probe set, and LSI DiGeorge 22q11.2(More)
