This is possible by means of multiple regression analysis of a data base from 467 evaluated female pelvis computed tomograms, calculation of intrapelvic soft tissue place requirements by means of correlative analysis of female computed tomograms and weight-/height-index, empirical determination of cut off values in borderline pelvi-fetometric constellations evaluating 190 births by means of logistic regression of the according pelvic-fetometric data.

Is there a relationship between mean arterial blood pressure and heart rate at rest and during standing? In a randomized study 161 clinically healthy pregnant women between 8th and 41st week of pregnancy were tested with a modified orthostatic test over defined time periods during pregnancy. Systolic and diastolic blood pressure and heart rate were registered in one minute intervals over a 30 minute period with an automatic Dinamap measuring device. This period was subdivided in a 10 minutes lying period, 10 minutes standing period followed by a 10 minutes lying period. There was a marked increase in systolic and diastolic blood pressure at rest with the beginning of the 34th week of gestation (p < 0.05 and p < 0.01). Despite this, maternal heart rate continued to rise over the whole course of pregnancy (p < 0.01). Furthermore, women with a fall in heart rate on standing were only seen in late pregnancy. Finally, pregnant women with a low mean arterial blood pressure (< or = 85 mmHg) did not experience a fall in blood pressure on standing more frequently than normal controls (> 85 mmHg).

There are two methods with different approach for retrospective diagnosis of gestational diabetes (GDM): 1. maternal postnatal oral glucose tolerance test (ppoGTT), 2. determination of cord blood insulin for detection of fetal hyperinsulinism. The presented study deals with the question how often macrosomia is correlated with pathologic cord blood insulin respectively pathologic ppoGTT and if both methods select identical collectives. Cord blood insulin was determined by RIA in 154 newborns with birth weight over the 90th percentile (threshold 15 microU/ml). On the 2nd day p.p. oGTT was performed in 80 women without prenatal diagnosis of GDM (threshold 95, 165, 145, 125 mg%). 37/154 (24%) newborns showed pathologic insulin values. 24/80 (30%) women had pathologic ppoGTT. In 30% of the cases pathologic results of cord blood insulin and ppoGTT selected different collectives: 17/66 pathologic ppoGTT with normal insulin values, 7/14 normal ppoGTT with pathologic insulin values. The only use of ppoGTT would fail in 50% of cases of GDM with proved fetal hyperinsulinism. The determination of cord blood insulin offers the opportunity of direct diagnostics on the child in contrast to maternal ppoGTT.
