    Notes: Summary. A total of 2771 pregnant women with gestational age esti-mated by ultrasound measurement of the fetal biparietal diameter (BPD) before the 22nd week of gestation were re-examined by ultrasound in the 32nd and 37th week of pregnancy at which time the fetal BPD and abdominal diameter (AD) were measured. An additional examination was performed at 34 weeks if the fetal weight in the 32nd week was estimated to be less than 95% of the expected mean weight. Light-for-gestational age (LGA) was suspected if the estimated birth-weight was less than 85% of the expected mean birthweight. This applied to 186 uncomplicated pregnancies in which there was no clinical suspicion of poor intrauterine growth. These pregnancies were randomly allocated to a treatment group (AD and estimated weight reported) or to a control group (AD and estimated weight withheld). Induction of labour was significantly more common in the treatment group (41%) than in the control group (15%). No statistically significant difference was found in the use of instrumental vaginal delivery or caesarean section. There was a Suggestion of marginal benefit in terms of neonatal morbidity but this was not statistically significant.

    Notes: The effect of external version under tocolysis with intravenous ritodrine during the 37th week of gestation was studied in a prospective randomized trial comprising 130 consecutive women with a fetus in breech presentation. Version was successful in 41% of the patients, all of whom had a cephalic vaginal delivery. Of the 56 women in the control group in whom version was not attempted; 8 (14%) converted to the vertex presentation spontaneously. Failure of version was significantly correlated with primiparity, location of the placenta on the anterior uterine wall, and maternal weight. The caesarean section rate was significantly lower in the version group (27%) than in the control group (46%) (P〈0–05). The overall caesarean section rate for a fetus in breech presentation was 50%. There were no serious complications associated with version and the condition of the infants at birth was better in the version group than in the control group. We advise external version under tocolysis in late pregnancy to reduce the frequency of breech presentation in labour.

    Notes: Simultaneous cardiotocography (CTG) and transcutaneous PO2 (tcPO2) measurements were made in a pregnancy complicated by membrane rupture and cord prolapse at 27 weeks gestation. A Caesarean section was not done because the fetus was judged to have little chance of survival and to be at very high risk of severe brain damage if it did. The fetus weighed 830 g and the CTG changes preceding fetal death were similar to those described by others. The tcPO2 was zero for periods of a few seconds to 20 minutes at 1 to 2 hours before fetal death, and the tcPO2 was constantly zero during the last 50 minutes of fetal life. Tracings showing the tcPO2/CTG changes preceding fetal death are reproduced.

    Notes: Transcutaneous scalp oxygen tension (tcPO2) was measured during labour in 40 fetuses, using a modified Clark electrode (Radiometer, Copenhagen). In 24 of the fetuses the recordings were of good quality during the second stage of labour. After delivery the acid-base status and oxygenation of the umbilical cord blood was measured. A correlation was found between the tcPO2 and umbilical artery oxygen saturation (r = 0.56, p〈0.01) and umbilical artery PO2 (r = 0.56, p〈0.01). Furthermore, a positive correlation was found between the area beneath the recorded tcPO2 curve during the last 10 minutes and the umbilical artery pH (r = 0.50, p 〈0.05). The data suggest that continuous transcutaneous PO2 measurement may be of value in monitoring high risk patients during labour.

    Notes: Summary. Birthweight-for-gestational age charts were based on the analysis of 3888 consecutive births in which the gestational age was estimated by measuring the fetal biparietal diameter before the 20th week of gestation. The data showed, in contrast to previous studies, a linear relation between gestational age and birthweight without inflection after term. The regression parameters showed a strongly significant difference between girls and boys. Thus, boys were 1·5% heavier than girls at 190 days gestation and 3·6% heavier at 300 days gestation. The linearity in the birthweight-for-gestational age charts could be due to the more reliable gestational age based on early ultrasound.

    Notes: Summary. This paper combines earlier results on the relation between birthweight and gestational age, and the relation between fetal weight and ultrasound measurements of the fetal biparietal diameter (BPD) and mean abdominal diameter (AD) to investigate whether preterm infants (viewed as a group) are smaller than unborn fetuses of the same gestational age. The birthweight distribution for each sex at 223 and 258 days gestation was derived from the birthweight-for-gestational age charts based on 3888 newborn infants. The sex-specific intrauterine weight distribution was estimated from ultrasound measurement of the fetal BPD and AD performed on randomly selected fetuses of gestational age 223 and 258 days. The birthweights were lower than the intrauterine weights, especially early in pregnancy and for female infants. Thus, the 10th birthweight centile for girls at day 223 corresponds to the 4th centile of the‘true’ intrauterine weight, and the‘true’ intrauterine 10th centile corresponds to the 25th centile birthweight at day 223.

    Notes: Objective To identify and test the predictive power of demographic, obstetric, and psychosocial risk factors of postpartum depression.Design Community-based, prospective follow up study based on questionnaires on past history of psychiatric disease, psychological distress and social support during pregnancy and depression at four months after delivery. Obstetric files were collected at time of birth.Setting Antenatal care clinic and delivery ward, Aarhus University Hospital, Denmark.Population 6790 women giving birth between 1 January 1994 and 31 December 1995, who attended the antenatal clinic during pregnancy; 5252 (78%) completed all questionnaires. The validation population comprised 528 women enrolled immediately prior to and after the study period.Main outcome measure Postpartum depression four months after giving birth assessed by the Edinburgh Postnatal Depression Scale.Results 5.5% of the women suffered from postpartum depression, corresponding to a score of 13 or higher on the Edinburgh Postnatal Depression Scale. Risk factors identified by multivariate logistic regression analysis included psychological distress in late pregnancy (OR 6.3 [95% CI 4.4–9.1]), perceived social isolation during pregnancy (OR 3.6 [95% CI 1.9–7.0]); high parity (OR 3.8 [95% CI 1.8–8.0]); and a positive history of prepregnant psychiatric disease (OR 2.1 [95% CI 1.4–3.2]). No association was found between pregnancy or delivery complications, and postpartum depression. The maximum predictive power of the identified risk factors was 0.3. According to these results, one out of three women who suffers from psychological distress in late pregnancy with perceived social isolation will develop postpartum depression.Conclusion Antenatal focus on psychosocial wellbeing may help to identify women at risk of postpartum depression.
