Catamnestic investigations in children with congenital hydrocephalus.
Catamnestic investigations on the course of pregnancy, family history and genetics were carried out in 141 children suffering from congenital hydrocephalus. The results were compared with those obtained from a group of non-malformed controls investigated by the same criteria. There was a considerably higher incidence of pregnancy disturbances (i.e. diseases, drugs, haemorrhage etc.) in mothers who later gave birth to a child with congenital hydrocephalus, than mothers of the control group (congenital hydrocephalus: 61.3% vs. controls: 30.1%). This high incidence of pregnancy disturbances could be particularly referred to a sevenfold increased rate of diseases and a fourfold increased rate of drug intake during the first trimester. There was also a higher rate of malformed relatives in children with congenital hydrocephalus (16.7%) than in controls (6.4%); not only were malformations of the central nervous system found to be increased but also malformations of other organ systems in relatives. This is interpreted as a hint not only at genetic influences but also at a generally higher incidence of malformations in a relatively small group of persons. Calculated figures of recurrence risk were in accordance with empirical data used in genetic counselling.
