[Abortion after the 12th completed pregnancy week. Report of experience of a specialist commission].

In the GDR abruptio after 12th completed week of gestation is only allowed in cases of severe threat of health or danger for life. The decision is made by a group of specialists. Analysing the years 1972-1986 all the 135 cases worked up by the commission of the district hospital of Gera were evaluated. Reasons for delayed diagnosis of pregnancy and arguments for wanted abruptio were most interesting. To determine possible trends, the results were subdivided in two periods, 1972-1979 and 1980-1986. In the second period an unfavourable development was detected regarding number of cases, distribution of age, number of preceded pregnancies, and gestational age. A special problem was the group of juvenile pregnant women. Social arguments were dominating, especially problems regarding the partners. Associated with them, indecision on bearing to maturity was a predominant reason for delayed diagnosis of pregnancy followed by disorders of menstruation. Social arguments may be reduced about 80% by consequent contraception methods. Proper and consequent application of oral contraceptives could avoid 70% of the late diagnoses. Teenager should be brought to contraception by more confidence in their families.

[The effect of noise on the feto-placental unit (epidemiologic and experimental study)].

Epidemiologic investigations on pregnant working women with noise exposure in ear damaging range didn't astonish in regard to essential parameters like average birth weight, average duration of gravidity, hyperemesis gravidarum, abortion frequency and disablements in comparison with a control group. In an experimental study 13 pregnant women in the 18th to 21st, 28th to 31st and 34th to 37st week of pregnancy were tested against a load of 75, 85 and 95 dB(A) via earphones and by means of cardiotocogram the derivations of foetal cardiac actions were taken. During all observation phases, all derived parameters are signated within the physiological deviations considering the gestational age.

[Longitudinal studies into alterations of vaginal flora during pregnancy on the basis of modern perinatal medicine (author's transl)].

Assessment of the uterine cervix score is a valuable method for early diagnosis of imminent premature birth, particularly in the context of high-risk pregnancy. Cervical insufficiency was recorded from 14 per cent of a high-risk group of patients. Longitudinal studies covered 110 probands with high-risk pregnancy and repeated vaginal examinations and 45 pregnant women with no vaginal examinations. No significant difference was found to exist between the two groups regarding percentual occurrence of potentially pathogenic aerobic germs, up to the 38th week of pregnancy. Highly significant decline in germ incidence was longitudinally recordable from both groups during the period of amnioscopy. Exposure to potentially pathogenic germs was not aggravated by repeated vaginal checks during pregnancy. Additional conclusions are drawn for practice.

[Tocometry and rheobase measurement for cervical insufficiency--contribution to pathogenesis of premature birth (author's transl)].

Longitudinal studies were conducted into 316 high-risk pregnant women, between the 25th and 37th weeks of pregnancy. Insufficiency of the uterine cervix was recordable from 42 women, accounting for 13 per cent of all probands. Tocometry and rheobase measurement were undertaken, complementary to case history evaluation, to elucidate pathogenesis in 30 cases. The mean rheobase value recorded from the above patients was lower with significance than that obtained from a control group. Values were below the lower normal limit in 76 per cent of the cases. Subjective symptoms were recorded by systematic interviews from 26 per cent of the probands. The conclusion drawn from all studies and examinations is that in the majority of all cases cervical insufficiency has been the result of latent, discontinuous labour. Hence, repeated vaginal examination of high-risk pregnant women is considered to be a method for early diagnosis of imminent premature birth. Conclusions are suggested for the practitioner.
