OBJECTIVE To study local response to BCG vaccination in twin babies and find out the effect of zygosity andchorionicity on BCG uptake. DESIGN Analytical observational study. SETTING Tertiary hospital. METHODS Twin pairs born in the hospital were evaluated for zygosity and chorionicity. BCG vaccination was given within 48 hours of birth to babies >/=33 weeks of gestation and birth weight >...

BACKGROUND We describe two cases of dichorionic triplet pregnancy after a frozen-thawed poor-stage embryo transfer. A 39-year-old and a 41-year-old woman underwent ART treatment. The first patient underwent intracytoplasmic sperm injection (ICSI) at 34 years of age, and two frozen-thawed poor-stage embryos were transferred at 39 years of age with assisted hatching, resulting in a trichorionic t...

OBJECTIVE To compare the placental volume at 11 + 0 to 13 + 6 weeks' gestation between singleton and multiple pregnancies and to examine the possible effect of chorionicity on placental volume. METHODS The placental volume was measured by three-dimensional (3D) ultrasound using the Virtual Organ Computer-aided AnaLysis (VOCAL) technique in 290 consecutive twin and 37 triplet pregnancies at 11...

OBJECTIVE To examine the distribution of fetal nuchal translucency (NT) thickness in dichorionic twins and investigate the effect of the correlation between NT measurements in each twin pair on the performance of screening for trisomies. METHODS The distribution of fetal NT for crown-rump length (CRL) was examined in 5646 dichorionic twin pregnancies, including 103 with fetal trisomies 21, 18...

background and aim: horseshoe placenta is a variant of ring-shaped placenta. ring-shaped placenta is a rare anomaly seen in fewer than 1 in 6000 deliveries, which could be seen as horseshoe shape due to atrophy in a portion of the ring. this report refers to a possible relationship between the horseshoe shape placenta and preterm labor; although it has not been yet validated in the literature. ...

OBJECTIVE To evaluate the association between first-trimester growth discordance and adverse pregnancy outcome in dichorionic twin pregnancies. METHODS This was a retrospective cohort study of consecutive women with dichorionic twin pregnancies undergoing an ultrasound scan at our institution between 7 and 14 weeks' gestation. Study groups were defined by the presence or absence of ≥ 11% crow...

A 25 years old, 4 gravida was admitted to the labor room on 16 July 2004 at 2:10 p.m with 9 months amenorrhea, and labor pain with leaking for 5 hours. She had three normal deliveries, the last one 4 years back. She had three antenatal visits, the first at 36 weeks gestation and the last 2 days before admission. Sonography done at 38 weeks, showed a single, live, intrauterine pregnancy. Within ...

INTRODUCTION Triploid pregnancies have an increased risk of early preeclampsia. Twin pregnancies consisting of one healthy fetus and one complete or partial molar, with or without a triploid fetus, are rare and management is complex. CASE PRESENTATION A 33-year-old Caucasian woman presented with a dichorionic diamniotic twin pregnancy. One fetus showed early growth restriction resulting in fe...
