[Prenatal diagnosis of sialidosis, a defect of the lysosomal enzyme neuraminidase].

Sialidosis, a lysosomal storage disease, ranged as oligosaccharidosis, is a genetic enzyme defect with a significantly restricted survival rate of the child concerned. After the preceded birth of a child who died of sialidosis, we succeeded in the correct prenatal exclusion of the disease with the prediction of a heterocygotic carrier status by biochemical analysis of cultivated amnion cells. The growth of these cells as well as the postnatal examined fibroblasts was significantly reduced.

Idiopathic thrombocytopenic purpura in pregnancy and neonatal period.

In pregnancy and neonatal period both mother and child are endangered by bleeding complications due to maternal idiopathic thrombocytopenic purpura. Obstetrical and perinatal management therefore must aim at increasing maternal and fetal platelet count. In our paper six patients in nine pregnancies are reported.

Treatment of idiopathic thrombocytic purpura in pregnancy by high-dose intravenous immunoglobulin.

ITP in pregnancy may lead to fetal thrombocytopenia caused by the transplacental passage of maternal antiplatelet antibody. The most hazardous complication in the infant is intracranial hemorrhage. In addition ITP in pregnancy is reported to be associated with an increased abortion rate and an elevated fetal morbidity and mortality.
