    Notes: Between mid-July and the end of August in 1977 and 1978, wheat bulb flies were caught in white water-traps at 16 oviposition sites in eastern Scotland. The numbers of females caught per site and the subsequent egg populations, estimated from soil-cores from each site, were linearly related. Water-trapping may therefore provide a reliable and early forecast of egg numbers, independent of soil-sampling, and so enable seed treatment to be limited to years when the risk of damage is great.

    Notes: Summary. From a study of 2000 consecutive labours the outcome of the 684 primigravid patients admitted in spontaneous labour has been examined according to their cervimetric progress during the first stage of labour. A partogram and labour stencil were used to identify dysfunctional labour which was treated with a standard protocol of augmentation by oxytocin. This policy achieved labours with a mean‘observed first stage’ of 6.3 h and a caesarean section rate of 8.7%. There was one stillbirth due to multiple congenital abnormalities and no increase in perinatal morbidity. Our data show that the type of first stage cervimetric pattern is helpful in predicting the outcome of labour. A normal cervimetric pattern resulted in a vaginal delivery rate of 98.4%; primary dysfunctional labour, which could be improved by oxytocin, had a 93.8% incidence of vaginal delivery, but if there was no improvement in the rate of cervical dilatation when this was administered the vaginal delivery rate was only 22.7%. A prolonged latent phase was associated with a caesarean section rate of 16.7% and the incidence of neonatal intubation was nearly as high as that found in uncorrected primary dysfunctional labour. The neonatal asphyxia in secondary arrest was minimal with an overall caesarean section rate of 28.4%; there was no increased incidence of neonatal morbidity with this cervimetric type.

    Notes: In order to distinguish between a maternal, fetal or maternal and fetal genetic predisposition towards severe pre-eclampsia, the first pregnancies of 158 mothers and 160 mothers-in-law of pre-eclamptic women and of matched controls were analysed. Fourteen per cent of mothers of pre-eclamptics were found to have had severe pre-eclampsia, confirming previous suggestions that the condition‘runs in families', in contrast to only a 3% incidence amongst mothers of controls. The incidence in mothers-in-law of both pre-eclamptics and controls was 4%, in full agreement with a maternal genotype hypothesis and suggesting that the fetal genotype plays, at most, only a minor role in the aetiology of severe pre-eclampsia. The data are in agreement with the hypothesis that a single recessive gene acting in the mother could be responsible for severe pre-eclampsia, but multifactorial inheritance is not ruled out. Mild pre-eclampsia showed no such familial tendency, indicating that the mild and severe forms of pre-eclampsia may represent separate pathological entities.

    Notes: Summary. The smoking habits of 2000 consecutive pregnant women have been analysed in relation to their race, social features and obstetric results. Only 60% of white patients were non-smokers compared with 80% of blacks and 90% of Asians, and whereas 20% of white patients smoked heavily only 3% of blacks or Asians did. Smokers booked later and were more frequently unsure of their dates, unemployed, unmarried and defaulters from the antenatal clinic. The incidence of antepartum haemorrhage was doubled amongst the heavy smoking multigravid patients in spite of a slightly decreased incidence of hypertensive disease. More non-smokers required induction of labour for raised blood pressure, and more smokers for fetal distress. The most significant differences between the smokers and non-smokers were the decrease in mean birth-weight associated with increased smoking (3.31 kg for non-smoking primi-gravidae compared with 3.14 kg for heavy smokers) and the threefold increased incidence of small-for-dates babies amongst the heavy smokers. There was no significant difference in the perinatal mortality.

    Notes: The incidence of fetal breathing movements (FBM)*, fetal trunk movements (FTM), and total fetal activity (TFA) was assessed in 100 normal pregnancies between 28 weeks and term. One 30-minute recording was made from each patient between 0900 and 1700 hours. The mean incidences of FBM, FTM and TFA were respectively 37±26 (SD) per cent, 18±10 per cent, and 53±24 per cent. The mean breathing rate was 48±12 per minute, and the mean number of movements per 30-minute study period was 29±15. There was a slightly higher incidence of FBM postprandially, but this failed to reach statistical significance. The mean incidence of FBM was lower before 31 weeks and after 40 weeks, compared to that between 31 and 40 weeks, when the values of FBM and FTM were constant. The breathing rate was directly related to gestational age. The mean number of movements per 30-minute study period was inversely related to gestational age, but the duration of movements increased progressively towards term, so that the incidence of FTM was constant throughout the third trimester. There was only one recording of TFA below 10 per cent.

    Notes: Summary. A prospective controlled study of 2000 patients to determine the incidence of postmaturity and the effect of a policy of non-induction of labour in prolonged pregnancy is reported.‘Certain postmaturity’ was identified in 4% of the patients and was associated with an increased incidence of babies with Apgar scores of 〈5 at 1 min; induction of labour at 42 weeks gestation did not affect the neonatal outcome compared with that in patients allowed to go into spontaneous labour. Induction of labour in patients designated as‘certain postmature’ and‘uncertain postmature’ reduced the number of vaginal deliveries and increased the caesarean section rate from 9.6 to 26.7 and from 2.2 to 31.2% respectively. The failure to improve the perinatal outcome does not support or justify induction of labour for uncomplicated postmaturity.

    Notes: Summary. From a study of 2000 consecutive labours, the outcome of 847 multigravid patients admitted in spontaneous labour was examined. Labour was classified according to the cervimetric pattern, and response to oxytocin given according to a strict protocol with the use of a nomogram and partogram. The mean ‘observed first stage’ was 3·4 h, and the caesarean section rate 1·4%. Normal labour occurred in 88·5%, with a vaginal delivery rate of 99·5% in this group. Stimulation was indicated in 98 patients (11·6%), augmentation improving the rate of progress in 86 (87·8%) of these, with vaginal delivery occurring in all but one. Successful accelerated labour was not associated with any increase in neonatal morbidity as judged by Apgar scores, intubation or transfer to the special care baby unit. Twelve patients did not have improvement following augmentation and seven were delivered by caesarean section, including one following a potentially preventable uterine rupture. The greatest neonatal morbidity was in the group with primary dysfunctional labour that did not improve with augmentation. It may be that this was related to the mode of delivery rather than augmentation, as there was no significant difference in neonatal condition between normal and abnormal labour if vaginal delivery occurred.

    Notes: Summary. A detailed analysis of 2632 consecutive pregnancies in white, black and Asian women, who were delivered during the period 1978 to 1980, found significant differences between the three ethnic groups. Asian primiparae had the longest first and second stages of labour, with the highest incidence of prolonged latent phase (14%) and primary dysfunctional labour (30%). Black primiparae and multiparae had the highest incidence of secondary arrest in the first stage of labour (10% and 4% respectively) and of primary dysfunctional labour, with the greatest recourse to emergency caesarean section (13% and 4% respectively). The mean birthweight for singletons born between 37 and 42 weeks was 3.37 kg for white babies, 3.25 kg for black babies and 3.14 kg for Asian babies. There was no racial difference in perinatal mortality or morbidity in this survey.

    Notes: The incidence of fetal breathing movements (FBM), fetal trunk movements (FTM), and total fetal activity (TFA) was assessed in 25 pregnancies complicated by maternal diabetes mellitus; 20 mothers had been juvenile insulin dependent diabetics, 4 were diagnosed during pregnancy (one of whom required insulin) and there was one other who was changed from chlorpropamide to insulin during the first trimester of pregnancy. Thirty-minute records were made postprandial between 32 and 38 weeks making a total of 161 recordings. There were 15 well-controlled insulin-dependent diabetic women with uncomplicated pregnancies; and in this group the mean percentage incidence of FBM was 60±25 (SD) per cent, FTM 16±10 (SD) per cent and TFA 73±22 (SD) per cent. The mean breathing rate per minute was 53±12 and the mean number of movements per 30-minute period 29±18. The incidences of FBM and TFA were significantly higher than those found in postprandial recordings in normal pregnancies. There was only one recording out of 115 where the incidence of TFA fell below 10 per cent. The mean percentage incidences of FBM, FTM and TFA were similar in the four uncomplicated pregnancies in which diabetes was diagnosed during pregnancy. The mean percentage incidence of TFA was significantly lower in the six pregnancies with obstetric complications, and levels of TFA below 10 per cent correlated well with abnormal cardiotocograph traces or fetal distress in labour.
