BACKGROUND: There is controversy whether chromosomal microarray (CMA) can replace karyotyping in prenatal diagnosis. Chromosomal microarray may detect more clinically significant chromosomal imbalances than karyotyping in a shorter time but does not detect inversions, triploidies or low mosaicisms. CASE REPORT: Amniocentesis was performed in the late second trimester based on ultrasound abnormalities. A CMA, obtained at 10 days, demonstrated a terminal deletion in 4q34...

Ultrasonography is a common component of prenatal care worldwide and is often used in early pregnancy to determine gestational age, number of fetuses, fetal cardiac activity, and placental location. Patients and their families may also consider ultrasonography a social event, as it provides confirmation and reassurance of a normal pregnancy. Ultrasound screening is typically scheduled in the second trimester to visualize fetal anatomy and confirm gestational age. Most ultrasound examinations are reassuring, but some incidentally identify structural anomalies and soft markers for aneuploidy, making it necessary for health care providers to correctly interpret these findings...

PURPOSE: To assess the need for postnatal evaluation and the medium term outcome in patients with isolated unilateral low grade prenatally detected hydronephrosis. MATERIALS AND METHODS: We prospectively selected 424 patients (690 kidney units) with a prenatal diagnosis of urinary tract dilatation between 2010 and 2013. We included only those patients with isolated unilateral low-grade hydronephrosis who underwent at least 2 postnatal ultrasound examinations. The Society for Fetal Urology (SFU) grading system was utilized for assessment of the hydronephrosis...

Oesophageal atresia with trachea-oesophageal fistula is a rare foregut malformation that requires surgery soon after birth. Prenatal ultrasound diagnosis is based on the presence of polyhydramnios, a small or non-visible fetal stomach and the blind ending oesophagus, called the upper pouch (1). Neonates present with salivation, coughing, choking and attacks of cyanosis. A diagnosis of oesophageal atresia is confirmed by inserting a nasogastric tube and a thoraco-abdominal X-ray.

In 2004 the Danish National Board of Health changed its screening recommendations. Since 2005 a first trimester screening for Down syndrome and a prenatal ultrasound screening for congenital anomalies in the second trimester of pregnancy has been offered to all pregnant women. The aim of this study was to describe the prevalence of cleft lip with or without cleft palate and cleft palate in a Danish area and to describe associated anomalies and the development in prenatal diagnosis over time. The study was based on data from the EUROCAT Registry for Funen County...

INTRODUCTION: Pyruvate dehydrogenase deficiency (PDHD) and pyruvate carboxylase deficiency (PCD) are diseases with severe neonatal forms, and their low prevalence makes them difficult to diagnose during pregnancy. Our objective was to describe prenatal ultrasound features that may be suggestive of these diagnoses. METHODS: We analyzed 3 cases from our institution and reviewed 12 published cases of PDHD and 6 cases of PCD, recording all of the ultrasound signs, as well as magnetic resonance (MR) findings when available...

The aim of the study described here was to identify an efficient criterion for the prenatal diagnosis of abnormal invasive placenta. We evaluated 129 women with anterior placenta previa who underwent trans-abdominal ultrasound evaluation in the third trimester. Spectral Doppler ultrasonography was performed to assess the subplacental blood flow of the anterior lower uterine segment by measuring the highest peak systolic velocity and resistive index. These patients were prospectively followed until delivery and evaluated for abnormal placental invasion...

In the presence of megacystis in the second half of pregnancy, with increased amniotic fluid, especially in a female fetus, the most likely diagnostic result is megacystis, microcolon, intestinal hypoperistalsis syndrome, MMIHS. In these cases, the diagnosis of MMIHS should be strongly considered instead of lower urinary tract obstruction.

Foetal sex determination using polymerase chain reaction (PCR) in mammals is based on the amplification of gender-specific foetal DNA sequences circulating in maternal blood. The bovine synepitheliochorial placenta does not allow a direct contact between the trophoblast and the maternal blood, resulting in difficult passage of foetal DNA and, consequently, its very small amounts in maternal bloodstream. Circulating cell-free foetal DNA (ccffDNA) encompasses short nucleotide fragments (300-600 bp) in maternal circulation...

BACKGROUND: Zika virus (ZIKV) is a mosquito-transmitted flavivirus, which can induce fetal brain injury and growth restriction following maternal infection during pregnancy. Prenatal diagnosis of ZIKV-associated fetal injury in the absence of microcephaly is challenging due to an incomplete understanding of how maternal ZIKV infection affects fetal growth and the use of different sonographic reference standards around the world. We hypothesized that skeletal growth is unaffected by ZIKV infection and that the femur length can represent an internal standard to detect growth deceleration of the fetal head and/or abdomen by ultrasound...

Introduction: The prevalence of major congenital anomalies (CAs) shows wide variations depending on geographical location and may range from <1% to 8% and it causes between 20% and 30% of perinatal deaths. In Nigeria, the prevalence of CAs may be underestimated with the general reliance on mostly livebirths ranging between 0.5% and 2.8% exempting cases of miscarriage and abortions. The purpose of this study was to determine the epidemiologic pattern and outcome of major CAs detected prenatally at the University College Hospital, Ibadan, Nigeria, over a 4-year period...

Introduction: Vesicoureteral reflux (VUR) is one of the most common ailments in children. Evidence-based guidelines recommend conservative treatment in children with VUR, followed by endoscopic surgery in those with breakthrough febrile urinary tract infections (UTIs). Despite this fact, the management of VUR is still controversial. Our objective is to evaluate the conservative strategy in children with primary VUR in terms of renal function and scarring, and identify factors associated with poor prognosis in those children...

Open spina bifida, also known as spina bifida aperta is a neural tube defect involving the lack of closure of vertebral arches and associated meninges and/or spinal cord abnormalities.Ultrasound examination is the gold standard for the diagnosis of spina bifida aperta. It represents the main imaging tool used to ascertain this diagnosis early in gestation. Three-dimensional ultrasound is necessary to detect the level and the size of the defect. Magnetic resonance imaging (MRI) represents a more sensitive tool, giving specific information of the defect and associated anomalies, playing an important role in ruling out differential diagnosis...
