[Smoking and pregnancy: search for a correlation between cotininemia and Doppler findings].

Objective: To search for a possible correlation between an effective marker of smoking and uterine and placental resistance during pregnancy.

Study Design: A prospective study was conducted at the Intercommunal Hospital Center of Montreuil, France: 81 healthy pregnant women underwent uterine and placental Doppler and cotidin blood assay, the best current test for smoking.

Results: This study shows a significative increase of utero-placental vascular resistances according with increased cotidine levels.

[Placenta percreta over a cesarean scar with bladder invasion. General review and 2 case reports].

The authors report two new cases of placenta percreta on a caesarian scar with invasion of the bladder. On the basis of a review of the literature, they demonstrate its seriousness, which is always increased by the unexpected nature of the complications. They therefore recall the clinical and paraclinical factors which can provide grounds for suspecting this possibility, so that the hemostasis hysterectomy required can be carried out on the best possible conditions.

[Meta-analysis of management seeking to prevent ovular infection].

The prevention of chorioamnionitis after preterm rupture of membranes is still controversial. This is due to the lack of power of most studies. These seem to show that the outcome is mostly determined by the gestational age at membrane rupture and a trend at lower chorioamnionitis when antibiotics are used.

[Uterine bladder fistula after a cesarean. A case report].

The authors report a case history of a vesico-uterine fistula after a caesarean section which was proven by histerography. It presented as the loss of urine together with blood at the periods, which they treated at first by using analogues of LH-RH in order to dry up the loss. They, using this case, have analysed the literature on vesico-uterine fistulae after caesarean operations.

[Late abdominal pregnancy. A case report].

A case of 29 weeks gestation abdominal pregnancy is reported as an illustration to a study of that rare gestation mostly occurring in developing countries. Most abdominal pregnancies are secondary. The most common clinical signs are the abdominal pain and uncomfort.
