[Harmful effects in early pregnancy--results of a teratological counseling center].

: In the years 1986, 1987, and 1988 altogether 132 consultations were conducted during pregnancy at the Landesfrauenklinik Linz. These pregnant women had all been exposed to potentially harmful influences (drugs, maternal diseases and as infections or cancer, X-rays or pregnancy despite IUD). In most of the cases we recommended carrying the pregnancy to full term; only a few were interrupted, sometimes against on recommendation to proceed with the pregnancy. The rate of abortion and the frequency of ectopic pregnancies were within normal limits. Due to personal investigations after birth we registered postnatal findings in nearly all cases. No serious malformations were recorded. Detailed teratological knowledge is necessary for correct advice at consultation after exposure to harmful influences during early pregnancy. In most cases it is possible to avoid interruption without risking an increased rate of malformations.
