1. 1. Fetal Anomalies : Surveillance and Diagnostic Accuracy of Ultrasound and Magnetic Resonance Imaging

   Författare :Hashem Amini; Ove Axelsson; Johan Wikström; Pelle Lindqvist; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pregnancy termination; fetal anomalies; antenatal diagnosis; ultrasound; second trimester; fetal MRI; CNS anomalies; pregnancy management; non-CNS anomalies; fetal autopsy; birth defects registry; ascertainment; spina bifida; cleft lip palate; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; Obstetrics and gynaecology; Obstetrik och gynekologi; Obstetrik och gynekologi; Obstetrics and Gynaecology;

   Sammanfattning : The aims were to investigate the accuracy of ultrasound in diagnosis of structural fetal anomalies with special focus on false positive findings (I), to evaluate the additional value of second trimester fetal MRI on pregnancy management (II-III) and to estimate the ascertainment in the Swedish Birth Defects Registry and incidence of spina bifida and cleft lip/palate (IV). Retrospectively, 328 fetal autopsies were identified where pregnancies were terminated due to ultrasonographically diagnosed fetal anomalies. LÄS MER

3. 2. Ultrasound screening for fetal anomalies

   Författare :Annamari Nikkilä; Lund Obstetrik och gynekologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sexuality; Obstetrik; andrology; congenital malformations; ultrasound; gynekologi; andrologi; reproduktion; sexualitet; reproduction; gynaecology; Obstetrics; fetal diagnosis;

   Sammanfattning : We studied the prenatal detection rate of various malformations during a study period of 16 years in a population in southern Sweden consisting of 141 240 deliveries. The overall detection rate was 28.4% and the false positive diagnoses were very few. LÄS MER

4. 3. Prenatal diagnosis of structural malformations and chromosome anomalies : Detection, influence of Body Mass Index and ways to improve screening

   Författare :Eric Hildebrand; Marie Blomberg; Tomas Gottvall; Jan Brynhildsen; Ove Axelsson; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Introduction: Prenatal diagnosis of structural malformations and chromosome anomalies is possible in the presence of an effective screening with ultrasound during pregnancy. The continuous evolution of the ultrasound equipment facilitates the examination. LÄS MER

5. 4. Pregnancy Ultrasound Detecting Soft Markers – the Challenge of Communicating Risk Figures

   Författare :Annika Åhman; Anna Sarkadi; Christine Rubertsson; Peter Lindgren; Marie Berg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pregnancy; Ultrasound; Soft markers; Prenatal; Screening; Fathers; Informed decision making; Decision aid.; Obstetrik och gynekologi; Obstetrics and Gynaecology;

   Sammanfattning : This thesis focuses on expectant parents’ experiences and needs when soft makers are detected at mid-trimester ultrasound, resulting in an unexpected assessment of risk for fetal anomalies. The thesis also describes the prevalence of ultrasonographic fetal soft markers and the incidence of Down syndrome in a low-risk population of 10,535 pregnant women with a total of 10,710 fetuses, as well as the risk of invasive prenatal diagnostics in conjunction with the detection of soft markers.

   Sammanfattning : Diabetes mellitus in pregnancy causes congenital malformations in the offspring.The aim of this work was to characterize biochemical and morphologic anomaliesin the conceptus of an animal model of diabetic pregnancy. In addition, apreventive treatment against diabetes-induced dysmorphogenesis was developed. LÄS MER
