Oxytocin Administration in High-Intensity Focused Ultrasound Treatment of Myomata.

Objectives: The aim of the study was to evaluate the clinical efficacy of magnetic resonance-guided High-Intensity Focused Ultrasound (HIFU) in patients with symptomatic uterine fibroids (myomata) after application of oxytocin.

Methods: 156 women with symptomatic uterine fibroids were treated using MR-guided HIFU procedure. 51 patients had additional IV administration of 40 IU of oxytocin in 5% Glucose or 0,9% NaCl solution during therapy.

Influence of first trimester biochemistry methodology on detection rate in screening for trisomy 21.

Objectives: The purpose of the study was to compare detection rates (DR) of FMF-certified and non-certified biochemical tests (BC) in trisomy 21 screening at 11-13 + 6 weeks.

Material And Methods: In 2267 singleton pregnancies FMF-certified doctors measured crown to rump length (CRL) and nuchal translucency (NT). Serum samples were tested for free β-hCG and the PAPP-A using 2 analysers (Delfia - Perkin Elmer and Immulite 2000 - DPC), the results were expressed in MoM values and used for computer calculation of the risk for trisomy 21.

Screening for trisomy 21 based on maternal age, nuchal translucency measurement, first trimester biochemistry and quantitative and qualitative assessment of the flow in the DV - the assessment of efficacy.

Objectives: The aim of the study was to compare effects of addition of two methods of ductus venosus (DV) flow assessment: qualitative - the assessment of shape of the A-wave (positive or negative), and quantitative - based on the pulsatility index for veins (DVPI) to the basic screening for trisomy 21 at 11 to 13 + 6 weeks of pregnancy.

Material And Methods: The ultrasound examination was performed in 8230 fetuses in singleton pregnancies at 11- -13 + 6 wks, as a part of a routine screening for chromosomal defects. In DV A-wave was assessed and DVPI was calculated.
