ABSTRACT
We report on the outcome of 82 amniocenteses (AC) carried out during pregnancies after in vitro fertilization (IVF) from 1-1-1985 to 31-12-1989. The main indication for amniocentesis was a maternal age of greater than or equal to 35 years. In 48 cases, we found an anterior placenta and assumed that this was related to the position in which the uterine embryo transfer was performed. In six pregnancies, we found an abnormal karyotype, including two cases of trisomy 21; the two couples decided for abortion. Four aberrations in the fetal karyotypes were also present in either the mother or the father, the resulting children are healthy. The further course of pregnancies after IVF and AC was characterized by a higher incidence of toxemia, uterine bleeding before the 28th week of gestation, abruptio placentae, and premature deliveries, when compared to the course of pregnancies after spontaneous conception. We believe that these occurrences were not caused by AC, as the incidence was higher in all our pregnancies after IVF (without AC) and has also been reported in pregnancies after ovarian hyperstimulation without IVF. Therefore, we see no reason to renounce AC after IVF. However, the special risks inherent in pregnancies after IVF must always be discussed with the couple.

Basing on clinical experiments the efficiency of Cervin preparation in treatment of necks of teeth hypersensitivity has been estimated. The experiments have been carried out in 52 patients for 171 teeth with denuded and hypersensitive tooth necks. Basing on the results obtained it has been found that the preparation gave satisfactory results in the form of regression or decrease of ailments and it can be used for neutralization of tooth necks in course of parodontopathy.

The purpose of the study was to investigate the clinical state of the mucosa of the oral cavity, the paradontium and dentition in workers of Siarkopol in Gdansk. Stomatologic examinations were performed in 105 workers who had been exposed to the action of sulphur dust. The subjects examined, showed inflammatory changes in the mucosa of the oral cavity (72,4%) and nontypical erosion of tooth enamel (11,4%). 74,28% of the subjects examined showed changes in the paradontium. The oral cavity of all Siarkopol workers was found to be in a poor state of hygiene.
