  • Editor's comment: Prof. Jim Thornton: The ten group system has been developed by Robson in 2001 to classify the different types of labour and audit Caesarean section rates in relation to labour induction. This paper updates the system and describes its use.

  • Editor's comment: Prof. Jim Thornton: The WHO Neonatal Health Research Priority Setting Group surveyed 132 of the world’s most productive neonatal researchers to prioritise unanswered research questions in newborn health, and produce a “top ten” list. The number one priority was “Can simplified neonatal resuscitation program delivered by trained health workers reduce neonatal deaths due to perinatal asphyxia?”

  • Editor’s comment: Prof. James Drife: Pregnancy after placenta accreta
    Placenta accreta results in hysterectomy in about 25% of cases, but in the others conservative treatment is successful. If a woman chooses to have another pregnancy, what are the risks? A recent study found a high risk of recurrent placenta accreta and a fourfold increase in risk of postpartum haemorrhage compared to a control group. This study reports similar findings. Nevertheless a history of placenta accreta was not a risk factor for overall perinatal mortality and was associated with a lower risk of hypertensive disorder in subsequent pregnancy.

  • Editor’s comment: Prof. James Drife: Adjuvanted vaccines in pregnancy: are they safe?
    Pregnant women were one of the high-risk groups for whom vaccination was recommended in the “swine flu” pandemic of 2009. The vaccine used in The Netherlands contained an adjuvant to boost the immune response. Information on its safety was limited to showing a lack of teratogenesis, but the immune response affects placentation throughout pregnancy. This case-control study of pre-eclampsia and intra-uterine growth restriction in 2010 provides reassurance that neither condition was associated with the adjuvanted vaccine.

  • Editor’s comment: Prof. James Drife:  Off-label prescribing in pregnancy: time for action
    Pharmaceutical companies may be reluctant to apply for a product to be licensed for use in pregnancy. This has two results. Effective medications are now being prescribed “off-label”, and women are being denied optimal treatment because some doctors are apprehensive about prescribing it. This important Editorial calls for urgent action on this long-standing problem. Professional societies have an important role, and the Editorial is accompanied by a review from the French College on the off-label use of misoprostol in obstetrics and gynecology.

    Off-label prescribing in pregnancy—a case of risky business or business as usual?
