First trimester screening for Down syndrome is yet to become the first intention strategy in France. This screening program at 11-14 weeks of gestation using maternal age, fetal nuchal translucency, maternal serum free beta-human chorionic gonadotropin and pregnancy-associated plasma protein-A has already been validated for a long time by many international studies. It seems to improve detection rate and decrease false positive rates. We report here five years prospective experience., (Copyright 2010 Elsevier Masson SAS. All rights reserved.)

We report and analyze four new cases of spontaneous twin anemia-polycythemia sequence (TAPS) and discuss antenatal management by fetoscopic laser coagulation for this uncommon form of chronic intertwin transfusion. The clinical course and placental characteristics of four pairs of monochorionic-diamniotic (MCDA) twins with spontaneous TAPS, of which one was treated with fetoscopic laser surgery, are described. For the three cases that did not undergo intrauterine intervention, serial Doppler measurement revealed a gradual increase in the middle cerebral artery peak systolic velocity (MCA-PSV) in the donor and a concomitant decrease in the recipient. These twins were born at between 32 and 34 weeks' gestation by Cesarean section. At birth, the donor twins were severely anemic and the recipient twins were polycythemic. Placental injection studies revealed a few small arteriovenous (AV) and venoarterial anastomoses. In the fourth case, because of the high suspicion of TAPS on MCA-PSV data at 24 weeks' gestation, fetoscopic laser coagulation of three small AV anastomoses was successfully performed. No hematological abnormalities were detected at birth. TAPS is a newly described form of chronic twin-to-twin transfusion associated with chronic anemia in the donor and polycythemia in the recipient, without twin oligo-polyhydramnios sequence (TOPS). The monitoring of MCDA pregnancies should include measurement of MCA-PSV in both fetuses even in the absence of intertwin discordance in amniotic fluid volume. Early detection of TAPS could indicate fetoscopic laser coagulation of AV anastomoses. Copyright © 2010 ISUOG. Published by John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

The article presents a study on the congenital heart defect (CHD) screening of euploid fetuses to determine the presence of cystic hygroma colli and the value of nuchal translucency (NT) measurement. It states that retrospective analysis was carried out to examine 12, 910 euploid pregnancies between January 1995 and August 2007. The results show that 3.4 per thousand falls under the major CHD incidence and among the fetal CHD cases, 55 were diagnosed prenatally.
