P04.37: Three-dimensional ultrasound estimation of fetal renal volumes in the second and third trimesters

Transabdominal chorionic villus biopsy in second and third trimesters of pregnancy to determine fetal karyotype.

Transabdominal chorionic villus biopsy is an established method of obtaining material for analysing fetal chromosomes in the first trimester of pregnancy but has not been widely used for karyotyping in the second and third trimesters, when rapid results are required. The technique was evaluated in two groups of patients, comprising 106 at risk of having a fetus with chromosomal anomalies (105) ...

Fetal dorsalis pedis artery velocimetry in the second and third trimesters.

OBJECTIVES This study aimed to establish reference ranges for Doppler parameters of the fetal dorsalis pedis artery and to compare them with those of the anterior tibial artery. METHODS Dorsalis pedis artery velocimetry was performed in 138 singleton fetuses. Intraobserver repeatability coefficients and differences between measurements of bilateral legs were also evaluated. Comparisons were m...

efl students gender and socioeconomic status: the use of politeness strategies in the first and second languages

within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...

Fetal Heart Assessment Using Three-dimensional Ultrasound

Cardiac anatomy is complex and often difficult to visualize or comprehend. 3D echocardiography is an area undergoing rapid development that represents a natural extension of conventional sonography methods which require integrating a series of 2D image slices to develop a 3D impression of underlying anatomy or pathology. This paper will review some of the basic concepts behind three-dimensional...
