DESIGN Prospective study on the sonographic prediction of chorionicity at 10-14 weeks of gestation. PARTICIPANTS During a 30 month period, from October 1997 to May 2000, 165 women attending the departments of fetal medicine or(More)
OBJECTIVE The purpose of this study was to evaluate the impact of noncentral placental cord insertion on birthweight discordance in twins.

OBJECTIVE Most studies of falls among older people have focused on those with some degree of balance or mobility impairment. This study aimed to establish whether falls and associated injuries were a major problem among healthy, older women, whether there were some common features in the falls, and whether these falls could be accurately predicted.

We report a case of fetal parvovirus B19 infection which appears to have resulted in hydrops in the first trimester. An ultrasound scan performed at the booking visit of a woman in the first trimester showed generalised oedema. Karyotyping to exclude a fetal abnormality was normal. Maternal radioimmunoassay serological investigations showed parvovirus B19(More)
A population of 2029 pregnant women (929 primiparas; 1100 multiparas) has been used to examine aspects of the calculation of obstetric risk scores from the presence of individual risk factors. The findings have been related to fetal outcome in these pregnancies and the following conclusions were reached: (1) the use of Bayes theorem for the calculation of a(More)
OBJECTIVE To determine the degree of agreement between prenatal ultrasound diagnosis of brain abnormalities and subsequent pathologic findings. METHODS Between August 1993 and August 1999 there were 62 cases where a fetus with a prenatal ultrasound diagnosis of a brain abnormality other than neural tube defects underwent autopsy at the Regional Department(More)
OBJECTIVE To examine the genital tract flora in women with preterm prelabour rupture of the membranes and to determine the relationship of these microorganisms to those found in fetal blood and amniotic fluid. DESIGN Prospective study of 97 patients with preterm prelabour rupture of the membranes. SETTING Maternal-fetal medicine centre. METHODS High(More)
OBJECTIVE To examine the pattern and prospective risk of intrauterine fetal death (IUFD) in twin pregnancy by chorionicity. DESIGN Retrospective cohort analysis.
