Presentation of ventriculomegaly at 11-14 weeks of gestation: An analysis of longitudinal data.

Objectives: The aim of this study was to examine the value of the sonographic measurements of the choroid plexus and the lateral ventricles at 11-14 gestational weeks in fetuses that had the diagnosis of second-trimester ventriculomegaly (VM) as a clinical reference.

Methods: The standard axial plane used for biparietal diameter measurement from 2D stored images in the first trimester was used to calculate the ratio between the choroid plexus and lateral ventricle diameter (PDVDR), the choroid plexus and lateral ventricle length (PLVLR) and the choroid plexus and lateral ventricle area (PAVAR) in 100 normal and 15 fetuses diagnosed with second-trimester VM.

Results: In fetuses with VM, the measurements of PDVDR, PLVLR and PAVAR were all significantly smaller compared to normal fetuses (p = < 0.

Decreased neonatal pain response after vaginal-operative delivery with Kiwi OmniCup versus metal ventouse.

Background: Vaginal delivery, especially operative assisted vaginal delivery, seems to be a major stressor for the neonate. The objective of this study was to evaluate the stress response after metal cup versus Kiwi Omnicup® ventouse delivery.

Methods: The study was a secondary observational analysis of data from a former prospective randomised placebo controlled multicentre study on the analgesic effect of acetaminophen in neonates after operative vaginal delivery and took place at three Swiss tertiary hospitals.

A prenatal prediction model for total nucleated cell count increases the efficacy of umbilical cord blood banking.

Background: The most important factor for the selection of an umbilical cord blood unit (CBU) for hematopoietic stem cell transplantation is the total nucleated cell (TNC) count as a surrogate marker for stem cell content in the CBU. At present, about one in five donors can provide a CBU with a sufficient TNC count for umbilical cord blood (UCB) banking. It is labor-intensive to obtain consent of all eligible donors and optimization of the selection is needed.

Cell-free fetal nucleic acids as prenatal biomarkers.

Introduction: Cell-free fetal nucleic acids in maternal plasma or serum have become important tools in the pursuance of new methods for non-invasive prenatal diagnosis, such as the determination of fetal blood groups and fetal gender. During these pioneering explorations, elevations in the concentration of these new-found biological analytes were noted in several pregnancy-related disorders, including preterm labor, pre-eclampsia and malimplantation. As these elevations appeared to occur before onset of clinical symptoms, it was proposed that such analyses might assist in screening for at-risk pregnancies.

[Ultrasound findings in fetal infection].

Infections acquired in utero or during the birth process are a significant cause of fetal and neonatal mortality and an important contributor to early and later childhood morbidity. Advances in ultrasound, invasive prenatal procedures and molecular diagnostics have allowed in utero evaluation and given rise to more timely and accurate diagnosis in infected fetuses. Transplacental transmission of the infectious agent, even in subclinical maternal infection, may result in a severe congenital syndrome.

[Sonographic diagnosis of gestational trophoblastic disease in early pregnancy].

Gestational trophoblastic disease (GTD) is classified as a metastatic or non-metastatic lesion, furthermore, villous GTD is distinguished from non-villous GTD. Because of their higher incidence and their risk of persistent gestational trophoblastic neoplasia (pGTN), early diagnosis of molar pregnancies is of clinical importance. Advances in ultrasound (US) technology and frequent application of transvaginal sonography in early pregnancy have changed the clinical and pathological presentation of molar pregnancies.

[Prenatal diagnosis of diastematomyelia and tethered cord - a case report and review of the literature].

Diastematomyelia is a rare form of occult spinal dysraphism. It is characterized by longitudinal clefting and separating of the spinal cord by a bony or fibrous spur. Diastematomyelia is associated with other anomalies, i.

Prenatal diagnosis of an infratentorial subdural hemorrhage: case report.

We report a case of a prenatally diagnosed infratentorial subdural hemorrhage. The hematoma located in the posterior cerebral fossa was detected by conventional ultrasound at 24 weeks of gestation. Intrauterine magnetic resonance imaging confirmed the diagnosis.

Influence of volume preloading on uteroplacental and fetal circulation during spinal anaesthesia for caesarean section in uncomplicated singleton pregnancies.

Objective: Effects of volume preloading during spinal anaesthesia for elective caesarean section on maternal blood pressure, feto-maternal circulation and fetal outcome.

Patients And Methods: In a pilot study a randomised trial was performed in 22 healthy women with uncomplicated, singleton pregnancies at 36-40 weeks of gestation undergoing elective caesarean section under spinal anaesthesia. In the low volume group (group A) patients received 150 ml of crystalloid solution for preloading, in the high volume group (group B) they were given 15 ml/kg of crystalloid solution for preloading before the initiation of spinal anaesthesia.

[Ultrasound indications of fetal chromosome abnormalities in the 2nd trimester].

The most common fetal chromosomal disorders have structural abnormalities, which can be detected during second trimester ultrasound examination. Major malformations, also known as hardmarkers, when single or in combination, should raise the suspicion for a specific syndrome. But it is known, that even more subtile findings can increase the background risk based on the maternal age, especially for Down syndrome.

Efficacy and safety of intravenously administered iron sucrose with and without adjuvant recombinant human erythropoietin for the treatment of resistant iron-deficiency anemia during pregnancy.

Objective: This study was undertaken to determine the efficacy and safety of intravenously administered iron sucrose with versus without adjuvant recombinant human erythropoietin in the treatment of gestational iron-deficiency anemia resistant to therapy with orally administered iron alone.

Study Design: Forty patients with gestational iron-deficiency anemia were randomly assigned to receive intravenously iron sucrose plus recombinant human erythropoietin or iron sucrose alone twice weekly. Target hemoglobin value was 11.

Umbilical cord blood collection before placental delivery during cesarean delivery increases cord blood volume and nucleated cell number available for transplantation.

Objective: We sought to determine whether umbilical cord blood collection during cesarean delivery can be improved by collecting cord blood before delivery of the placenta.

Study Design: Patients undergoing cesarean delivery were randomly assigned to cord blood collection before or after placental delivery. Closed sterile collection systems were used for blood sampling.

Induction of fetal hemoglobin synthesis with recombinant human erythropoietin in anemic patients with heterozygous beta-thalassemia during pregnancy.

Objective: Recombinant human erythropoietin (rhEPO) increases fetal hemoglobin synthesis in nonpregnant thalassaemic patients. We used rhEPO in 4 pregnant patients with heterozygous beta-thalassemia and anemia to study its effect on erythropoiesis, F cell production, and HbF synthesis.

Methods: Patients were treated with a combination therapy of rhEPO and iron.
