At the turn of the century, several Western countries introduced prenatal screening for Down syndrome. Technology became widely and easily available, and the combination of ultrasound and then blood tests made it possible to screen the entire pregnant population. For the first time in history, there was a chance of detecting, and eventually aborting, most instances of Down syndrome, and at rela...
متن کاملUltrasound evaluation of fetal gender at 12-14 weeks.
AIMS The aim of this study was to assess the feasibility and accuracy of fetal gender assignment by transabdominal ultrasound at 12-14 weeks of gestation. METHODS Fetal gender assessment was performed in 1222 singleton pregnancies. In all fetuses the crown-rump length (CRL) was measured and the genital area of the fetus was examined in the mid-sagittal plane. The result of ultrasound examinat...

The fetus had four normally formed legs and arms.Antenatal ultrasound images are supplemented by post natal photograp...
متن کاملADAM 12 as a first-trimester maternal serum marker in screening for Down syndrome.
BACKGROUND A Disintegrin And Metalloprotease 12 (ADAM 12) is a glycoprotein synthesised by placenta and it has been shown to be a potential first-trimester maternal serum marker for Down syndrome (DS) in two small series. Here we analyse further, the potential of ADAM 12 as a marker for DS in a large collection of first-trimester serum samples. MATERIALS AND METHODS The concentration of ADAM ...
متن کاملADAM 12 as a second-trimester maternal serum marker in screening for Down syndrome.
BACKGROUND ADAM 12 is a placenta-derived glycoprotein that is involved in growth and differentiation. The maternal serum concentration of ADAM 12 is a potential first-trimester maternal serum marker of Down syndrome (DS). Here we examine the potential of ADAM 12 as a second-trimester maternal serum marker of DS. MATERIALS AND METHODS The concentration of ADAM 12 was determined in gestational ...
