    Notes: Summary. An angiotensin II sensitivity test and a supine pressor test were done consecutively at 28 weeks gestation in 90 healthy, normotensive nulliparous women. None of the supine pressor tests was positive, applying the predefined threshold of a rise of 20 mmHg in diastolic blood pressure after rolling over; nine tests were positive using a corrected 9 mmHg cut-off level. Ten women had a positive angiotensin sensitivity test using a threshold of the effective pressor dose of 8 ng/kg/min; 22 women were positive using an effective pressor dose of 〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:14700328:BJO817:ges" location="ges.gif"/〉10 ng/kg/min. Later in pregnancy 12 women (13%) developed pregnancyinduced hypertensive disease (PIH). The specificity of both tests of predicting the development of PIH was about 90%. The sensitivity of the angiotensin sensitivity test at the 10 ng/kg/min level was 92%. Because of its low sensitivity of 25% the supine pressor test appears to have no value for the prediction of PIH. There was a significant positive association between angiotensin IT refractoriness and birthweight.

    Notes: A nonradioisotopic technique for determination of platelet lifespan was applied to 19 healthy women whose gestational ages were between 32 and 40 weeks. Nine non-pregnant women and five men were also studied. Platelet counts were performed in all subjects. No significant difference was demonstrated between platelet lifespan in pregnant women (9·2 days), in non-pregnant women (9·7 days) and in men (9·2 days). There was no significant difference between platelet counts in men and in non-pregnant women, but the mean number of platelets in pregnant women was significantly lower. It is concluded that no significant changes in platelet behaviour appear to occur in normal pregnancy.We are grateful to Mrs P. Rotmans and Mr E. Haddeman for their advice and technical help.

    Notes: Labour was induced with repeated intramuscular injections of 125 or 250 μg of a 15-methyl analogue of prostaglandin F2α (15-me-PGF2α) in 97 women harbouring a dead fetus for 1 to 42 days in the second or third trimester of pregnancy. The 24-hour cumulative expulsion rate was 93 per cent in 35 nulliparae and 95 per cent in 61 multiparae in whom labour was successfully induced. There was one failure in a parous patient. The median time interval between the first injection and delivery was significantly longer in nulliparae (10.4 hours) than in parous women (7.3 hours). There were no important differences in efficacy or side effects between the 125 and the 250 μg dosage scheme. No serious complications occurred, but gastrointestinal side effects were prominent. It is concluded that these side effects are compensated for by the simplicity, efficacy and safety of the procedure.

    Notes: Summary. The effect of repeated external cephalic version, performed at between 33 and 40 weeks gestation, on presentation at delivery was studied in a randomized controlled trial comprising 180 pregnant women with breech presentation. No tocolysis, analgesia or anaesthesia was used. Approximately 25% of all attempts in the study group of 90 women were successful; repeated external version resulted in cephalic presentation at delivery in 48% of patients. Spontaneous version to cephalic presentation occurred in 23 (26%) of the 90 women in the control group in whom version was not attempted, indicating a therapeutic gain from the procedure of 22%, with a 95% confidence interval of 8 to 35%. No severe complications of external cephalic version were noted. We conclude that external cephalic version reduces the frequency of breech presentation at delivery. This mainly benefits the mother because of the decrease in the number of caesarean sections and their inherent maternal morbidity.

    Notes: The hourly fetal urine production rate (HFUPR) was calculated from ultrasonic measurements of fetal bladder volume. A normal HFUPR reference curve, constructed from measurements in 189 normal pregnancies between 24 and 42 weeks gestation, showed a rapid increase of HFUPR from 3·3 to 24·4 ml up to 40 weeks followed by a slight decline. The amniotic fluid volume was estimated by the p-aminohippuric acid method within 12 hours of HFUPR measurements. In 67 normal pregnancies, there was no relationship between HFUPR and amniotic fluid volume measured between 36 and 41 weeks gestation. In 12 patients with fetal growth retardation, a relationship was found between reduced fetal urinary output and low amniotic fluid volume between 36 and 38 weeks gestation. In the 16 diabetic patients studied between 28 and 40 weeks gestation, there was no relationship between HFUPR (within or below normal range) and the high amniotic fluid volume (above 1500 ml in 13 patients). The implications of these findings are discussed.

    Notes: Summary Fetoscopy with rigid fiber optics was performed under general anesthesia in 9 patients scheduled for therapeutic abortion by hysterotomy with a duration of pregnancy between 12 and 18 weeks. Visualization of fetus and placenta was found to be at random chance and incomplete, and could not be improved by internal or external manipulation. Skin biopsies were obtained in 5 cases. The cord could be recognized in all cases. It is concluded that the haphazard and incomplete visualization of the uterine contents at present precludes the application of second-trimester fetoscopy for early detection of visible congenital fetal abnormalities.

    Description / Table of Contents: Zusammenfassung Untersucht wurde der Zusammenhang zwischen einigen symptomatisch deutlich definierten Spätgestoseformen (monosymptomatische und polysymptomatische Gestose und essentielle Hypertonie) und den morphologisch scharf umschriebenen rezenten, ziemlich rezenten und alten Placentarinfarkten. Zu diesem Zweck wurden 494 Placenten, verteilt in eine normale Kontrollgruppe und eine pathologische Gestosegruppe, systematisch untersucht. In der pathologischen Gruppe wurden Infarkte häufiger und in größerer Anzahl gefunden als in der Kontrollgruppe, die Lokalisation war überwiegend zentral und parazentral. Bei Placentarinfarkten waren das Geburtsgewicht und die Apgar Scores der Kinder signifikant niedriger. Nach der Meinung des Autors sind Placentarinfarkte nicht pathognomonisch für Gestose, sie müssen vielmehr betrachtet werden als sichtbare Indicatoren einer verminderten Durchblutung des Uterus, welche vor allem bei Spätgestose gefunden wird.
    Notes: Summary The relation was investigated between some symptomatically clearly defined forms of toxemia of pregnancy (monosymptomatic and polysymptomatic toxemia and essential hypertension) and the morphological strictly described recent, fairly recent and old infarcts of the placenta. For this purpose 494 placentas, divided into a normal control group and a pathologic group from patients with toxemia of pregnancy, were systematically examined. In the pathologic group infarcts were found more frequently and in a greater number than in the control group, with a preference for a central and paracentral localisation. Placental infarcts were significantly correlated with a low Apgar Score and birth-weight of the newborn. According to the author, infarcts are not pathognomonic for toxemia of pregnancy, but have to be regarded as visible indicators for a diminished maternal circulation in the uterus, which is especially found in toxemia of pregnancy.
