[Hypertensive complications in pregnancy--a special evaluation of the Rhineland-Pfalz perinatal study].

In a special analysis of the perinatal database Rheinl.-Pfalz of the years 1989 and 1990 1,876 pregnancies with the risk-factor "gestosis" (2.4% of all deliveries) were evaluated. In comparison to all deliveries (n = 78,250) significantly different incident-rates could be observed: Sterility, working during pregnancy, nationality, parity, psycho-social stress, multiples, adipositas, diabetes mellitus, pathological increase of body weight, urinary infection, number and duration of antenatal hospitalisation. Prematurity and fetal retardation as well as placental insufficiency, pathological antenatal CTG, green amniotic fluid and intrapartel acidosis was seen much more often in the risk group, resulting in a much higher rate of caesarean section (50.1 versus 13.7%) and an increased maternal and fetal morbidity. Perinatal mortality was twice as high in the risk group compared to the control. Thought data quality is limited in this study covering a very larger area, the results underline the unchanged importance of hypertensive disorders in perinatology.

[Prenatal diagnosis of fetal teratomas].

Teratomas are the most frequent tumours in a newborn child. Prenatal ultrasound allows an early diagnosis with high significance. Six cases are described by prenatal sonographic signs, clinical management and pathologic-anatomic findings. Since teratomas are mostly benign and surgery is often successful, sufficient cooperation between obstetricians, surgeons and neonatologists is important.

Sonographic prognostic factors in prenatal diagnosis of SCT.

OBJECTIVE: A subset of fetuses with sacrococcygeal teratomas (SCT) develops hydrops caused by high-output heart failure. Identification of fetuses at risk for hydrops is important because surgical intervention may reverse the pathophysiology of the disease. The aim of this study was to evaluate sonographic prognostic factors regarding tumor morphology and vascularity associated with the development of hydrops in utero. METHODS: Over a 10-year period, we identified 7 fetuses with SCT diagnosed antenatally and managed at the University of Mainz. We retrospectively reviewed the charts of mothers and infants and recorded data on prenatal diagnosis, tumor size and localization, perinatal management, neonatal care, and fetal outcome. RESULTS: The diagnosis of SCT was made in all cases by ultrasound. The median gestational age at the time of initial diagnosis was 23 weeks. In 3 cases, signs of fetal heart failure were detected by ultrasound. Pathological blood flow in the venous system was further noted in 2 cases. One fetus developed hydrops. The mean gestational age at delivery was 35 weeks, depending on the presence or absence of maternal or fetal complications. Six infants were delivered by cesarean section, and 1 by vaginal delivery. After fetal stabilization, surgery was performed in 5 of 7 cases. Inadequate ventilation secondary to prematurity was a contributing factor to death in 1 fetus. One fetal intrauterine death occurred at 27 weeks of gestation. CONCLUSION: Pregnancies with antenatally diagnosed fetal SCT necessitate frequent monitoring to ensure the detection of fetal/maternal complications by ultrasound and Doppler ultrasound. The most important prognostic criteria were cardiomegaly, fetal hydrops, and increased preload indexes of the fetal venous system as sign of fetal heart failure. Many studies show that the occurrence of pulsations in the umbilical vein of a hydropic fetus correlates with a poor fetal outcome. The decision on the optimal time of delivery should therefore be made by a multidisciplinary team of specialists.

[Histology of chorioamnionitis: relations to maternal and fetal infection parameters].

With regard to clinical diagnosis and prognosis, intrauterine infection continues to pose major problems for obstetricians. In recent years serum assay of CRP, an acute phase protein, has become firmly established in the obstetric management of premature rupture. We investigated the relationship between histologically confirmed chorioamnionitis and maternal and fetal inflammation parameters in 69 patients on the basis of inflammation of the membranes, placenta and cord occurring in histomorphologic stages. Our results show the C-reactive protein to be a sensitive and specific indicator of chorioamnionitis and closely correlated with both the histologic stage and the severity of the chorioamnionitis. We therefore advocate adoption of the histologic result as the "gold standard" for evaluating subclinical and clinically manifest forms of intrauterine infection.

[Ultrasound imaging of the symphysis fissure for evaluating damage to the symphysis in pregnancy and postpartum].

In a cross-sectional study of 211 patients with a normal pregnancy the distance of the symphysis was sonographically measured during pregnancy and normal values were evaluated. Physiologically a continuous widening of the symphysis was shown up to 3 mm an average. The sonographical sign of the damage of the symphysis was a deviation in widening and also a difference in height. The value of the sonographic examination is shown in 2 cases with damage of the symphysis and compared to the x-ray picture results.
