This review of literature describes the first-trimester nuchal translucency (NT) which forms the basis of new form of screening which can lead to a significant improvement in detection of congenital anomalies as compared to second trimester screening programs, the so called genetic-sonogram. A growing body of evidence-based studies has demonstrated that fetal NT can be a powerful prenatal scree...
nuchal translucency (nt) measurements in the first trimester screening between 11 and 14 weeks’ gestation are regarded as a clear marker for aneuploidies. the presence of a thickened nt, even if the karyotype is normal, can be associated with structural abnormalities. having an abnormal screening of nt, parents and physicians could face dilemma over abortion particularly in a case of ivf/icsi f...
we have devided the thesis in to five chapters. the first recollects facts from purely algebraic theory of jordan algebras and also basic properties of jb and jb* - algebras which are needed in the sequel. in the second chapter we extend to jb* - algebras, a classical result due to cleveland [8]. this result shows shows the weakness of jb* - norm topology on a jb* - algebera. in chapter three, ...
First-trimester (FT) ultrasound examination appears to have a very good sensitivity in the detection of fetal abnormalities, especially when an extended protocol that is achievable with reasonable resources of time, personnel and ultrasound equipment, is used. It has been shown that the efficiency of the routine anomaly scan varies widely between the studies performed both in early or mid-pregn...
Second trimester screening for Down's syndrome is widely practised throughout the world. We assessed the performance of antenatal serum screening for Down's syndrome with the quadruple test in 46193 pregnancies from 14 hospitals over 5 years. Women who screened positive (risk > or =1 in 300) were offered diagnostic amniocentesis or chorionic villus sampling. Of 88 observed Down's syndrome pregn...
