[External cephalic version of breech presentation at term]. / Ytre vending av foster i seteleie til termin.

BACKGROUND: External cephalic version could be an alternative to either vaginal delivery or caesarean section in breech presentation at term. MATERIAL AND METHODS: A systematic literature review about external cephalic version in breech presentation. RESULTS: The numbers of breech presentation delivered by caesarean section could probably be reduced in Norway by offering version, but this would not affect perinatal mortality.

Different levels of platelet activation in preeclamptic, normotensive pregnant, and nonpregnant women.

OBJECTIVE: The aims of our study were to determine the basal platelet activation state in women with preeclampsia compared with normotensive pregnant women and nonpregnant women and to investigate the platelet reactivity on in vitro stimulation with adenosine diphosphate or thrombin receptor activation peptide. STUDY DESIGN: Platelet expression of CD61 (fibrinogen receptor), CD42a (von Willebrand factor receptor), CD62P (P-selectin), CD63 (Glycoprotein 53), and PAC-1 binding (activated fibrinogen receptor) were determined in 20 pairs of women with preeclampsia/normotensive pregnant women and in 12 nonpregnant women, with the use of flow cytometry. RESULTS: Basal platelet expression of CD61, CD42a and CD62P, and adenosine diphosphate-stimulated CD62P expression were increased in women with preeclampsia compared with normotensive pregnant women. Platelets from women with preeclampsia and normotensive pregnant women differed from platelets from nonpregnant women by expressing higher basal CD63 levels and being more responsive to in vitro agonist stimulation, which was demonstrated by increased expression of CD61, CD62P, and CD63. CONCLUSION: This study supports the notion that platelets are important in the pathophysiologic condition of preeclampsia.
