Introduction: Multiple pregnancy is simultaneous development of more than one fetus in uterus. Multifetal gestations are found to be associated with significantly higher maternal morbidity and health care service costs. Women multifetal gestation nearly six times likely hospitalized complications, including preterm labor, preeclampsia, premature rupture membrane, placental abruption, hydramnios...

The development of congenital hypertrophic pyloric stenosis concurrently in both sibs of uniovular, as well as binovular, twin pregnancies is well documented and has been the subject of numerous reviews (Metrakos, 1953; MacMahon and McKeown, 1955). The condition has also been described in 3 (Cameron, 1955), 4 (Gailey, 1948), and even 5 sibs (Benson, 1970) in the same family. This is the first r...

In spite of the widespread use of assisted reproductive technology, there have been, to our knowledge, only two reported cases of molar pregnancies after gamete intra-Fallopian transfer and five reported cases after in-vitro fertilization and embryo transfer. We report here a case of a complete hydatidiform mole in a twin pregnancy after gamete intra-Fallopian transfer, as well as a case of a c...

BACKGROUND The coagulation protein von Willebrand Factor (VWF) is known to be elevated in pregnancy. However, the timing and nature of changes in VWF and associated parameters throughout pregnancy are not well understood. OBJECTIVES To better understand the changes in VWF provoked by pregnancy, we studied VWF-associated parameters in samples collected over the course of healthy pregnancies. ...

OBJECTIVES To examine the rate of cerebral palsy in twins and triplets in births from 1980 to 1989 in Western Australia and to identify factors associated with increase in risk. DESIGN Pluralities for all births in Western Australia were identified through the standardised midwives' notification system, and cases of cerebral palsy were identified from the Western Australian cerebral palsy reg...

Long-term genetic selection of cattle for fraternal twins has increased the frequency of twin and triplet ovulations. In contrast, the ratio of fetal numbers to ovulation sites in pregnant females with twin (0.83) or triplet (0.73) ovulations is <1.0 and the number of calves per parturition is 1.6 and 2.0, respectively. Failure of individual twin or triplet ovulations to yield a conceptus in fe...
