    Notes: Objective To determine clinical practice amongst bstetricians in the UK in the antepartum and intrapartum management of pregnant women with recurrent genital herpes infection.Methods All Members and Fellows of the Royal College of Obstetricians and Gynaecologists resident in the UK were sent a questionnaire requesting information concerning their management of pregnant women with recurrent genital herpes infection.Results There was a 76% response rate to the questionnaire. Of the 1201 obstetricians who responded, only 369 (31%) admitted to having a formal policy governing the management of herpes in pregnancy within their unit. However, regular screening was advocated by 718 (60%), of whom 463 (64%) performed regular antenatal swabs for viral culture. At the time of presentation in labour 974 obstetricians (81)routinely examined the genitals for evidence of a recurrence.When asked in what circumstances caesarean section would be considered an appropriate method of delivery in women with genital herpes infection, 1107 (92%) felt that visible active lesions at the time of labour was sufficient. However, when the membranes had been ruptured for more than four hours in the presence of genital lesions, only 678 (56%) considered this an indication for caesarean section. Caesarean section was more likely to be considered appropriate in this situation by obstetricians who performed antenatal screening (χ2= 30.38, P 〈 0.0001). Five hundred and ninety-six obstetricians (50%) felt that a positive viral culture obtained at antenatal screening from the most recent occasion prior to presentation in labour was an indication for caesarean section, although of this group 192 (32%) said they did not perform antenatal screening by viral culture.The reporting of a recurrence by the patient without visible evidence of disease was considered an appropriate indication for caesarean section by 438 respondents (36%). Maternal request for caesarean section regardless of recurrences at delivery was onsidered an acceptable indication for operative delivery by 745 obstetricians (62%).Conclusions 1. There seems to be little agreement amongst obstetricians in the UK regarding the management of recurrent genital herpes infection in pregnancy. 2. The management possibilities are reviewed and suggestions are made for a more cohesive approach to the problem.

    Notes: Objectives To determine the effects of titrated oral misoprostol solution, compared with vaginal dinoprostone.Study design Open, randomised clinical trial.Setting Academic hospitals in South Africa and Liverpool, UK.Methods Women undergoing induction of labour after 34 weeks of pregnancy were allocated by randomised, sealed opaque envelopes, to induction of labour with titrated oral misoprostol solution, or two doses of vaginal dinoprostone (2mg) administered six hours apart. Failure to deliver within 24 hours of randomisation was the primary outcome on which the sample size was based. The data were analysed by intention-to-treat.Results Six hundred and ninety-five women were randomly allocated: 346 to oral misoprostol and 349 to vaginal dinoprostone. There were no significant differences in substantive outcomes. Vaginal delivery within 24 hours was not achieved in 38% of women in the oral misoprostol group and 36% in the vaginal dinoprostone group (RR 1.08; 95% CI 0.89-1.31). The caesarean section rates were 16% and 20%, respectively (RR 0.80; 95% CI 0.58-1.11). Hyperstimulation with fetal heart rate changes occurred in 4% of women in the oral misoprostol group and 3% after vaginal dinoprostone (RR 1.32, 95% CI 0.59–2.98). The response to induction of labour in women with unfavourable cervices was somewhat slower with misoprostol when membranes were intact, and with dinoprostone when membranes were ruptured. There were no differences in neonatal outcome between the two groups.Conclusions This new approach to oral misoprostol administration was successful in minimising the risk of uterine hyperstimulation, which has been a feature of misoprostol use for induction of labour, at the expense of a somewhat slower response in women with intact membranes and unfavourable cervices. Misoprostol is not registered for use in pregnant women, and further research is needed to confirm optimal and safe dosages.

    Notes: Objective To evaluate the efficacy and safety of a suppressive course of acyclovir in late pregnancy in women with recurrent genital herpes infection on the incidence of viral shedding, herpes lesion development and caesarean section for recurrent genital herpes.Design Double-blind, randomised placebo controlled clinical trial.Setting Adepartment of genitourinary medicine in Sheffield and an antenatal clinic in London.Population Pregnant women with recurrent genital herpes infection at 〈 36 weeks of gestation.Methods Participating women were given acyclovir 200 mg four times a day (or matching placebo) from 36 weeks of gestation until the time of delivery. Women were seen weekly and viral cultures were obtained from the cervix and vulva. Decisions regarding mode of delivery were left to the discretion of the attending obstetrician.Main outcome measures Delivery by caesarean section for recurrent genital herpes infection. Number of episodes of recurrent genital herpes infection and number of episodes of asymptomatic viral shedding during the treatment period. In addition blood was taken at two weekly intervals to determine acyclovir levels.Results The total number of women recruited was 63 (3 1 received acyclovir and 32 received placebo). The number of women undergoing delivery by caesarean section for recurrent herpes at the time of delivery was 12 (19%). The odds ratio for delivery by caesarean section in women taking acyclovir, compared with those talung placebo, was 0.44 (95% CI 0.09–1.59). The odds ratio for clinical recurrences during treatment was 0.10 (95% confidence interval 0.00–0.86) and the odds ratio for clinical recurrence or asymptomatic shedding during treatment was 0.32 (95% CI 0.05–1.56).Conclusion This trial was unable to demonstrate that acyclovir can significantly decrease the number of caesarean section deliveries; however, the number of clinical recurrences was significantly reduced. Two episodes of asymptomatic virus shedding both occurred in women taking acyclovir. At the present time there is little evidence to suggest that acyclovir should be used outside randomised controlled trials for the suppression of recurrent genital herpes infection during pregnancy.

    Notes: Objectives To determine whether the addition of antenatal thyrotrophin-releasing hormone (TRH) to corticosteroids, given to women at risk of preterm delivery, would decrease the risk of death and severe morbidity associated with prematurity.Design Two concurrent multicentre, double blind, randomised, placebo-controlled trials were designed with a common core dataset to be analysed as a single large pragmatic trial.Setting Hospital maternity units.Populations Pregnant women at risk of preterm delivery who had been prescribed a course of corticosteroids to enhance fetal maturation.Interventions Antenatal administration of TRH 400 μg every eight hours for four doses versus matching placebo.Main outcome measures Primary: death of the baby or chronic lung disease (defined as oxygen dependency at 28 days after birth). Secondary: other measures of respiratory morbidity, in particular respiratory distress syndrome. Other measures of short term neonatal morbidity including intraventricular haemorrhage and necrotising enterocolitis. Measures of maternal side effects.Results The antenatal TRH trial was halted early on the basis of external evidence. Overall a total of 225 women were recruited who delivered 275 babies. The primary outcome of death or chronic lung disease occurred in 33 babies in the TRH group and 43 babies in the placebo group (RR 0.8, 95% CI 0.5–1.2). There were no other differences between the two groups. Stratified analysis did not reveal any differences between the two groups depending on how long before the time of delivery the mother had received the TRH or placebo.Conclusions These trials are too small to provide convincing evidence of the effect of antenatal TRH on neonatal outcome. When added to the existing systematic review and meta-analysis, however, these data should provide evidence on which subsequent practice can be based. The process by which the trials were monitored and stopped is of relevance to future trials.

    Notes: [Auszug] Two cultivars of wheat (Triticum aestivum L.), Maris Huntsman and Val, were grown in pots in the open from November 1975 to July 1976, and tillers were removed to maintain a constant density of 320 shoots per m2. The plants reached anthesis on 7 and 8 June, Val being the earlier, and attained a ...
