The uterine cervix is to be seen as a biochemical, physical and anatomic unit with a good correlation to the uterine corpus. The function of the cervix for the protection of the pregnancy depends from many biochemical processes, in which collagen has a very important role, influenced by structural and biochemical changing of the connective tissue and by the balance of biosynthesis and destruction of collagen. The controlling function of Estrogen, Progesterone and Corticoids seems to be demonstrated. Prostaglandins have a direct influence on the ripening processes of the cervix and correlation to the oxytocic influence of the uterine contraction. In clinical management and for examination of premature labour, cervical ripeness at term and post-term situations and for indicated initiation of labour we must use a cervix-score with different evaluation of its parameters as length, consistency, position and dilatation of the cervix as well as the station of the fetal head.
In the first half of pregnancy ultrasound investigations was made on women with known gestational age by regular menstruation or conception. In 221 cases of single pregnancies fetal crownrump length was measured. Biparietal cephalometry was performed in 198 single fetuses. All examinations were done with a Kranzbühler Linearscanner using an ADR 3.5 MHZ transducer. Growth curves and the velocity of growth from biparietal diameter and from crown-rump length were determined and compared. The accuracy of the estimation of gestational age was observed to be +/- 10 days (2 SD) with both methods. A difference in accuracy could not be found. Even if the first half of pregnancy was separated in an early and a late part there wasn't any improvement of accuracy.
Pelvic presentation deliveries in the period between 1975 and 1981 were analyzed and compared with a randomly chosen group of vertex presentation deliveries from the same period. On clarification of the group of patients delivered of pelvic presentations, the mortality rate was comparable with that resulting from vertex presentation. In both groups of patients both the mortality and acidosis morbidity rates were affected by the tendency towards premature birth. In cases of pelvic presentation, caesarian section represents the least risky method of delivery. Particularly in the event of premature birth, caesarian section should thus be given preference in all cases. Given careful individual diagnosis, mature infants -even, selectively, in the case of women giving birth for the first time--can be vaginally delivered from the pelvic presentation position.
A survey is given about the general theories of beginning of labour. In this topic the influence of excitation of the uterus muscle is explained together with the importance of hormonal induction.
The authors analyze under the aspect of data offered by medical literature, the clinical aspects and occurrence of the microbial flora in the necrotizing fasciitis. The clinical symptoms are presented in correlation with the aerobic, anaerobic and mixed bacterial specificity with the purpose of a suitable antibacterial therapy. Further, there are presented certain aspects of cutaneous "bubbly" lesions connected with the microbial flora in the NF.
