BACKGROUND Impact of fetal gender on prematurity has been primarily investigated in singleton pregnancies. In an attempt to understand better how fetal gender may affect gestational length in twin gestations after in vitro fertilization, same-sex twins and opposite twins were compared for pregnancy duration. METHODS This study evaluated 113 women at ages 20 to 39 years with consecutive dichor...

OBJECTIVE Women previously giving birth with cesarean section have an increased risk of postpartum hemorrhage (PPH) and retained placenta. The objective of this study was to determine if anterior placental location increased the risk of PPH and retained placenta in such women. MATERIALS AND METHODS We performed a prospective cohort study on 400 women with cesarean section delivery in a previo...

Background & aim: Cervical ectopic pregnancy is a rare variant of ectopic pregnancy, and placenta percreta is a complex and dangerous condition; patients with these conditions are difficult to manage. In this study, we present a rare case of placenta percreta in cervical pregnancy. Case report: A 32 -year-old woman with 19 weeks of gestation and gross hematuria was admitted to Qaem Hospital in ...

OBJECTIVE The objective of the study was to construct an ultrasound-based estimated fetal weight-for-gestational-age reference for twin fetuses, stratified by chorionicity. STUDY DESIGN We performed a retrospective cohort study of live-born nonanomalous twins delivered longer than 34 weeks at the Royal Victoria Hospital (Montreal, Canada). Fetal weight was estimated using ultrasound biometric...

OBJECTIVE To construct monochorionic diamniotic (MCDA) and dichorionic diamniotic (DCDA) twin reference ranges for umbilical artery (UA) pulsatility index (PI), UA resistance index (RI), fetal middle cerebral artery (MCA) PI and peak systolic velocity (PSV) and cerebroplacental ratio (CPR) from 24 weeks' to 38 weeks' gestation and compare these with published normal values for singleton pregnan...

The assessment of fetal growth is an essential component of good antenatal care, especially for twins. The aims of this study are to develop twin-specific intrauterine 'growth' charts, based on cross-sectional birthweight data, for monochorionic and dichorionic twins according to sex and parity, and to detect twins at risk for neonatal death by comparing the use of twin-specific and singleton c...
