[Obstetric aspects of post-cesarean section status].

A rising Caesarean delivery rate is the reason, why the obstetrician should be very well informed about the management of vaginal birth after Caesarean section: It is feasible in almost all women with nonrecurrent indication for the preceeding Caesarean section. Suspected foetal macrosomia, twin gestation and breech presentation represent relative contraindications. External cephalic version is a reasonable option. In case of history of uterine scar dehiscence or rupture and in women with vertical uterine scar, repeat section should be performed.

Bilateral stromal Leydig cell tumour of the ovary. Case report and literature review.

The stromal Leydig cell tumour of the ovary is a very rare benign neoplasm which usually occurs in postmenopausal women. Due to a significant production of androgens by the tumour, it is frequently associated with symptoms of virilization. To our knowledge only 7 cases have been reported in the literature, one of them with bilateral manifestation. We report an additional case affecting both ovaries in a 59-year-old nun with long-standing virilism, review the literature, and discuss the histomorphological features for differential diagnosis.

[Vascular malformations of the uterus].

Arteriovenous fistulae of the uterus are rare. We report on a patient with a vascular malformation of the uterus complicated by hypermenorrhea. Symptoms, possible complications and therapy are discussed.

[Macrosomia of the fetus and clinical relevance].

The clinical relevance of foetal macrosomia (i.e. birth weight greater than or equal to 4000 gms) was investigated retrospectively using the 1987 figures of the "Bayerische Perinatalerhebung". 8591 (total n = 101931; 8.4%) newborns met the criterion for macrosomia and were compared with two groups of normosomic newborns (birth weight 2500-2999 gms and 3000-3999 gms). The problems, which may obscure correct prenatal diagnosis are discussed. The incidence of operative deliveries and birth injuries was increased. The duration of the deliveries was not prolonged in our study in contrast to published reports. The neonatal transfer-rate to a neonatal centre was higher in newborns, delivered by Caesarean section, compared with newborns delivered by the vaginal route. The perinatal and the maternal morbidity was higher, the perinatal mortality lower in the macrosomic newborn. According to our data, macrosomia represents and elevated perinatal risk.

[Androgenization in postmenopause in rare ovarian tumors--2 case reports].

Androgen-producing tumours of the ovary are uncommon in postmenopausal women. We report on symptoms of two patients with androgenization due to a stromal-Leydig cell tumour and a steroid-cell tumour, respectively. Clinical signs and symptoms, laboratory findings and therapeutic consequences are discussed.

[Genital infections and the course of pregnancy: a prospective study].

The reported study investigates the relationship of genital infections, pathobiochemical findings and demographic data to preterm labor, premature rupture of membranes (PROM) and premature delivery. The predictability of chorioamnionitis, puerperal and neonatal infections by these parameters was evaluated concurrently. 301 patients were included in this study between July 1985 and June 1986. 147 of these patients were studied longitudinally during pregnancy, delivery and puerperium (longitudinal group). A second group consisted of 154 women who presented themselves on start of labor to the labor and delivery unit of our Department (peripartal group). The incidence of preterm labor and of PROM was 26%. The incidence of premature delivery, chorioamnionitis, puerperal and neonatal infection was 11.4%, 5.5%, 7.6% and 3% respectively. Cervical colonization with Mycoplasma hominis correlated positively with PROM (relative risk 2.2), premature delivery (3.9) and neonatal infection (6.9). Chorioamnionitis, premature delivery and puerperal infection were also significantly increased in patients with positive vaginal Ureaplasma urealyticum cultures during pregnancy and delivery. Premature delivery (2.8) and puerperal infection (4.0) were associated with a vaginal group B-Streptococci (GBS) colonization during pregnancy, as was a positive GBS culture during delivery associated with puerperal infection. Bacterial vaginosis also correlated positively with premature delivery (5.6) and puerperal infection. Preterm labor correlated negatively with the socioeconomic level, PROM correlated negatively with the marital status, positively with age, a history of cervical cerclage, conization or PROM during former pregnancies. Sexual intercourse more often than once weekly during the last month of pregnancy was also associated with an increased number of PROM. Gardnerella vaginalis, Candida and Trichomoniasis during pregnancy and delivery were associated with preterm labor and puerperal infections. Levels of maternal plasma fibrinogen concentrations in patients with PROM were elevated 48 hours after delivery in accordance to the characteristics of acute phase proteins. In contrast, the maternal PMN-granulocyte-elastase concentration was significantly elevated at time of delivery and 24 hours thereafter in those patients who developed puerperal infections. The derived positive predictive value was 26%, the negative 94.7%, respectively. The overall accuracy of the prediction was 83.1%. Six out of seven mothers with neonates treated because of neonatal infection showed significantly elevated plasma concentration of PMN-granulocyte-elastase.(ABSTRACT TRUNCATED AT 400 WORDS)
