I thank Steve Robson and his team of Editors for their very hard work over the previous years in establishing Fetal and Maternal Medicine Review (FMMR) as a reference point for authoritative reviews in the field of perinatology. I am delighted that Steve is staying on as an Associate Editor, and am very pleased to welcome Professor Neil Sebire (UK) and Professor Jimmy Espinoza (USA) as Associate Editors for 2013 issues onwards. Amanda Johns has taken over from Jean Birtles in the Editorial Office and can be contacted by email at fmr_editorial_office@cambridge.org.

It is our opinion that the evidence from epidemiological observations, clinical trials and biological studies is strong enough to support the view of different origin and phenotypes of pre-eclampsia: placental, which usually occurs (but not exclusively) early in pregnancy and is associated with poor early placentation of different severity with subsequent restriction of foetal growth, at different stages of gestation; and maternogenic, which generally occurs late in pregnancy and it is not related to placental insufficiency and foetal growth restriction.
