This study reviewed all cases of complete uterine rupture (UR) in pregnancy during the decade 1993-2002. In 69 412 deliveries, 5320 women had a single prior caesarean section. Of these, 4021 had a trial of labour and 3129 (77.8%) delivered vaginally. In nine (0.22%) cases, the previous transverse scar ruptured during labour. None of these nine ruptures resulted in maternal or fetal death, peripartum hysterectomy or fetal morbidity. In our practice, a trial of labour in women with a previous low transverse caesarean is associated with a high rate of vaginal delivery and a low rate of UR.
The objective of this study was to review the first 50 clinical pregnancies of women with polycystic ovarian syndrome (PCOS) who had ovulation induced either with metformin alone, or in combination with clomifene. The study was confined to women with PCOS attending our infertility service. A register of clinical pregnancies was maintained of women who conceived after metformin therapy. The metformin was continued throughout the first trimester. The outcome of pregnancy was determined by individual chart review. Of the 50 women, 21 conceived with a combination of clomifene and metformin, and 29 with metformin alone. Seven women had a first trimester loss and 43 had a live birth. There were no perinatal deaths, no neonatal seizures and no congenital malformations. There were also no multiple pregnancies. The overall caesarean rate was 37%, and none of the babies had an Apgar score less than 7, at 5 min. This study found no evidence of any adverse clinical effects when metformin is continued in the first trimester of women with PCOS following ovulation induction. There was also no evidence of an increase in the rate of miscarriage or multiple pregnancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
