AUTOMATED TELEHEALTH SYSTEM FOR FETAL GROWTH DETECTION AND APPROXIMATION OF ULTRASOUND IMAGES

One of the most profound use of ultrasound imaging is fetal growth monitoring. Conventionally, physicians will perform manual measurements of several parameters of the ultrasound images to draw some conclusion of the fetal condition by manually annotating the fetal images on the ultrasound device interface. However, performing manual annotation of fetal images will require significant amount of time considering the number of patients an obstetrician can have. In this paper, an integrated

Current knowledge on the use of ultrasound measurements of fetal soft tissues for the assessment of pregnancy development

Ultrasonography, with its detailed imaging of the fetus, is very widely used in obstetrics. The primary aim of ultrasound scanning in pregnancy is to limit the risk of obstetric complications by early detection of abnormalities, such as intrauterine growth restriction and macrosomia. Currently, morphometric formulae are used for estimating fetal weight. They utilize basic biometric parameters. However, Hadlock formula, used for fetal weight estimation, has an error rate of 20%. For this reason

Fetal ultrasound estimated weight and correlation to Brazilian newborn weight

Introduction Adverse events in the process of fetal growth can lead to consequences at later times and the extent of the damage depends on the nature, duration and severity. Two crucial determinants of fetal growth are the pregnancy duration and the fetal weight at a specific gestational age(1). As weight is easy to measure at birth, it is used as an indicator of fetal growth, and is included in the comparative statistics on perinatal health improvements. There is a wide variety of normal birth

Fetal cardiac function by three-dimensional ultrasound using 4D-STIC and VOCAL – an update

Introduction Congenital heart disease (CHD) occurs in one to two newborns per 100 live births and is an important cause of perinatal morbidity and mortality(1–4). Prenatal screening and diagnosis of anatomical and functional heart malformations are possible by ultrasonography and fetal echocardiography, allowing for planning of delivery and, in some cases, prenatal therapy, favoring the postnatal prognosis of CHD(5–7). Cardiac function is routinely evaluated in fetuses with anatomical

Gradual diagnosis and clinical importance of prenatally detected persistent left superior vena cava with absent right superior vena cava – a case report and literature review

Introduction At week 4 of gestation, the blood of the upper half of a fetal body is drained by the bilateral symmetrically arranged anterior cardinal veins. By week 8 they connect by an oblique anastomosis (future left brachiocephalic or innominate vein) and the part of the left anterior cardinal vein regresses. Persistent left superior vena cava (PLSVC) seems to be a remnant of this regressed vessel(1). Achiron et al. proposed a classification of fetal venous system anomalies, where PLSVC is

Prenatal ethanol intoxication and maternal intubation stress alter cell survival and apoptosis in the postnatal development of rat hippocampus

INTRODUCTION Ethyl alcohol (ethanol) is a well-known teratogen that impairs brain development (Ward and Wainwright, 1989; Miller and Montgomery, 1992; Michaelis and Michaelis, 1994). The cells in the central nervous system are highly vulnerable to adverse effects of ethanol and fetal ethanol exposure may cause a massive wave of apoptotic neurodegeneration in many different regions of the developing human brain.

Comparing intrapartum ultrasound and clinical examination in the assessment of fetal head position in African women

Introduction The fetal head position plays an important role in the mode of delivery and is one of the known predictors of labor outcome. Particularly, the persistent occiput posterior position might be associated with prolonged labor and operative delivery(1–3). Undiagnosed occiput posterior positions increase the risk of perineal lacerations and neonatal injuries in the process of delivery(4). An accurate method for determining the occiput position is therefore useful in assessing the

A reminder of peristalsis as a useful tool in the prenatal differential diagnosis of abdominal cystic masses

With routine antenatal ultrasound and recent advances in ultrasound technology, fetal intraabdominal cystic masses are recognized more often and are better characterized than in the past. They may be classified as solid and cystic, and may originate from multiple structures. When considering the extensive differential diagnosis of cystic masses, the observation of peristalsis narrows the possibilities to the gastrointestinal tract. To find this feature on ultrasound, the examiner must expressly

Development of a flow cytometric test for the detection of D-positive fetal cells after fetomaternal hemorrhage and a survey of the prevalence in D-negative women

A sensitive test for the presence of D-positive fetal red blood cells (RBCs) in the maternal circulation of D-negative women has been developed. It was used to investigate the possibility that the occasional failure in preventing alloimmunization might be due to the administration of inadequate amounts of prophylactic anti-D Rh immune globulin. The standard dose in Australia contains 125µg of antibody, and can suppress immunization by an estimated 6 mL of packed D-positive RBCs. A

Severe perinatal hemolytic disease due to anti-e

Hemolytic disease of the fetus and newborn (HDFN) is an alloimmune condition in which shortened survival of the red blood cells (RBCs) of the fetus or the newborn is caused by maternal antibodies passing through the placenta and binding to the corresponding antigen on the fetal RBCs. The pathogenesis of HDFN is based on a blood group incompatibility between the mother and fetus, where the fetal RBCs have antigens of paternal origin that are lacking on the mother’s RBCs. If the mother has an

Case report: a pregnant woman with immune thrombocytopenic purpura and unusual red cell antibodies

Maternal immune thrombocytopenic purpura (ITP) may lead to fetal platelet destruction. This process is mediated by IgG platelet autoantibodies that cross the placenta. In this case, not only were platelet autoantibodies present, but red cell alloantibodies anti-E, anti-M, and anti-He were also present. Anti-E, present as an IgG antibody, crossed the placenta, but did not cause clinical problems in the E+ newborn, other than possible hyperbilirubinemia that was treated by phototherapy.

Hemolytic disease of the fetus and newborn (HDFN) is one of the serious causes of perinatal morbidity and mortality. It occurs because of a difference in red blood cell (RBC) antigens between the mother and fetus. The mother is alloimmunized during pregnancy or after blood transfusion. The mother’s antibodies, when of the IgG class, enter the placental circulation, bind to fetal antigens on the RBC surface, and cause hemolysis and/or anemia as a consequence of erythropoiesis suppression.

Hemolytic disease of the fetus and newborn (HDFN) occurs when the pregnant mother is alloimmunized with immunoglobulin (Ig)G-type antibodies specific for antigens present on the red blood cells (RBCs) of the fetus. These antibodies cross the placenta, and hemolysis occurs when the maternal antibody binds to the fetal RBC antigens, generating a binding to the Fc receptor of macrophages in the spleen of the fetus. After delivery, the continuous destruction of RBCs can cause progressive anemia and

Infection results in a wide range of clinical manifestations, ranging from mild respiratory disease to fetal death and mucosal disease. The virus particles are small and contain a single-stranded, positive-sense RNA molecule of approximately 12.3 kb with one large open reading

related to fetal antigen expression and tissue distribution. The anti-Inb was further investigated using mono­cyte binding and inhibition studies. The absence of HDN in the pres­ence of potent anti-U remains unexplained. In general, antibodies with low ADCC activity do not cause HDN, but high ADCC activity does not always indicate severe HDN.

Can ultrasound be helpful in selecting optimal management methods for pregnancies complicated by placental non-trophpblastic tumors?

Placental chorioangioma is the most common subtype of non-trophoblastic placental tumors. Other subtypes are very rare and usually associated with an uneventful course of pregnancy. Most chorioangiomas are small and of no clinical significance. Giant chorioangiomas may be associated with serious fetal and maternal complications. So far, no established ultrasound guidelines are available for the management of placental non-trophoblastic tumors. This may be attributed to the rarity of the disease

Fertility outcome after saline sonography guided removal of intrauterine polyps in women with unexplained infertility

transvaginal scan was done to confirm a fetal heart beat. Follow up All women with polyps, whether they requested removal or not, were followed for a period of twelve months. The follow up was maintained via telephone calls and repeated transvaginal scans at 3, 6, 9 and 12 months. Those who did not comply with the follow up, were not included in the final statistical analysis. Those with recurrence of polyps were planned to have removal and follow up adjusted. The primary outcome measure was women who

Neonatal alloimmune thrombocytopenia due to anti-HPA-2b (anti-Koa)

Most severe cases of neonatal alloimmune thrombocytopenia (NAIT) are due to anti-HPA-1a (anti-PlA1) antibodies. We report a case of NAIT due to anti-HPA-2b that resulted in in utero intracranial hemorrhage.A 33-year-old G2P1A0 Caucasian woman had a routine ultrasound at 34 weeks. The fetus appeared to have a left hemispheric hematoma. IVIG, 1g/kg, was started immediately and administered weekly until delivery. One day after receiving the first dose of IVIG, fetal platelet count was 18 ×

First example of an FY*01 allele associated with weakened expression of Fya on red blood cells

. Phenotypematched units were desired for a multi-transfused Vietnamese fetus with α-thalassemia. Genotyping of the fetus using a microarray assay that interrogates three SNPs (c.1-67, c.125, and c.265) in FY yielded indeterminate results for the predicted Duffy phenotype. Genomic sequencing of FY exon 2 showed that the fetal sample had one wild-type FY*01 allele and one new FY*01 allele with the c.265C>T SNP, which until recently had only been found on the FY*02 allele. Genotyping performed on samples
