OBJECTIVE To update the likelihood ratio for trisomy 21 in fetuses with absent nasal bone at the 11-14-week scan. METHODS Ultrasound examination of the fetal profile was carried out and the presence or absence of the nasal bone was noted immediately before karyotyping in 5918 fetuses at 11 to 13+6 weeks. Logistic regression analysis was used to examine the effect of maternal ethnic origin and...

Background: Accurate determination of gestational age has become important for deciding the appropriate time termination pregnancy as well to monitor fetal growth during entire period pregnancy. Objective: The aim study was assess whether trans-cerebellar diameter, placental thickness or combining both them is more accurate assessment in 3rd trimester Patients and Methods: This a cross sectiona...

background: methamphetamine (ma) is one of most common illicit drugs which were reported that nearly half of ma consumers are women. ma can cross through placenta and affects pregnancy and fetus development. objective: our aim was to evaluate effects of injected ma on crown-rump length, head and placental circumference, body weight, histological changes and apoptosis in fetus. materials and met...

The changes in genital tract morphometry, foetal dimensions, the relative volumes of fluids during gestation was evaluated Red Sokoto (Maradi) does using 28 gravid genitalia. Based on ages fetuses, each genitalia classified into one three phases namely: early, mid and late for a comparison all parameters. While both uterus placenta were significantly enlarged, (P<0.05) at gestation, other mo...

The present study was undertaken to evaluate the accuracy of ultrasonography in early pregnancy diagnosis in goats. Ultrasonographic scanning with real time B-mode ultrasound machine having 5 MHz linear array transducer was performed on gravid uterus (n=24) obtained from slaughterhouse (Group I). Crown rump length (CRL) measured by ultrasound was found significantly different (p<0.05) with actu...

Introduction: The Parikh&rsquo;s formula is a calculation method that considers menstrual cycle duration in women who have an unusual interval of menstruation cycle. Since the accurate estimation of gestational age affects pregnancy outcomes, the present study aimed to compare the first trimester ultrasound and Parikh&rsquo;s formula in determining the Expected Date of Delivery (EDD). Mate...

RATIONALE Maternal smoking in pregnancy is associated with reduced birth weight and childhood lung function. This study determined when maternal smoking first influences fetal growth and how this relates to childhood respiratory outcomes. METHODS A longitudinal cohort of 1924 pregnant women was recruited. Fetal ultrasound measurements at 11 weeks (crown-rump length, CRL) and at 20 weeks gesta...
