The Kleihauer-Betke (KB) test evaluates fetal blood in the maternal circulation, and is often used when placental abruption is suspected. At our centre, it is the protocol to perform a KB test in all suspected cases of abruption. We carried out a retrospective study of all cases of abruption that occurred at our centre over 6 years. Of the 68 confirmed cases of placental abruption, only three had positive KB tests, giving a sensitivity of only 4.4%. Thus, in the overwhelming majority of cases of confirmed abruption, the KB test was negative. Our findings indicate that the KB test has poor sensitivity for placental abruption and should not be used in the detection of abruption.

OBJECTIVES: Data on rates of cesarean delivery among pregnancies diagnosed with genetic syndromes remains limited. We examined the cesarean delivery rates for Down syndrome pregnancies over a 10-year period in the US. METHODS: We used data from the 1995-2004 US delivery data files to examine cesarean delivery rates in singleton pregnancies (at ≥20 weeks' gestation) with and without Down syndrome. We further examined if the rates of cesarean deliveries in primary and repeat cesarean deliveries among Down syndrome pregnancies differed based on the presence or absence of major structural abnormalities or stillbirth or gestational age at delivery. RESULTS: There were 35 million singleton deliveries of which 19186 were diagnosed at birth with Down syndrome (1 in 2000 births after 20 weeks gestation). The primary cesarean delivery rates were higher among Down syndrome pregnancies (17.5% in 1995 and 21.5% in 2004) compared to non-Down syndrome pregnancies (12.3% in 1995 and 16.6% in 2004). Temporal trends for cesarean deliveries were steeper among Down syndrome pregnancies with gastrointestinal and heart abnormalities than in Down syndrome cases without abnormalities. Higher cesarean delivery rates were also noted among Down syndrome pregnancies ending in third trimester live born than in control. CONCLUSION: In the US, cesarean deliveries in Down syndrome pregnancies increases over time and is greater when Down syndrome is associated with structural abnormalities and delivered during the third trimester of pregnancy.

BACKGROUND: Management of pregnancy in a woman who has had a ruptured uterus on more than one occasion presents a great clinical and ethical challenge to the obstetrician. CASE: This appears to be the first report on complete uterine ruptures in three consecutive pregnancies. CONCLUSION: Prolonged hospital admission, intensive antenatal surveillance, antenatal steroid administration and elective premature delivery may give the best chance for a good outcome in these pregnancies. However, despite all these efforts, there is still a high risk of an unfavorable outcome.

We describe our aggressive management of a woman with a triplet pregnancy resulting from in vitro fertilization who presented at 22 weeks' gestation in labor with full cervical dilation. Successful multiagent tocolysis and delayed delivery of the two remaining fetuses after delivery of the presenting fetus led to an improved outcome for all three babies.

We report the prenatal diagnosis of vasa previa using transvaginal sonography and color Doppler. This case supports the previously reported association of vasa previa with second trimester low-lying placentas and in-vitro fertilization. Sonographic examination for vasa previa should be considered in pregnancies with low-lying placentas and those resulting from in-vitro fertilization.
