OBJECTIVES: To describe our screening population and audit of the performance of first-trimester screening for Down syndrome, based on a combined test, enhanced with additional ultrasound markers, over the whole period of the study. MATERIAL AND METHODS: We performed a prospective study from 2009 to 2016, which included 1358 singleton fetuses with a crown-rump length of 45-84 mm. The risk of aneuploidy was calculated using nuchal translucency, fetal heart rate (FHR), and additional markers, such as nasal bone (NB), tricuspid flow (TF) and ductus venosus (DV), combined with maternal serum free β-human chorionic gonadotropin (fβ-hCG) and pregnancy-associated plasma protein-A (PAPP-A)...

The microscopic examination of fifty-five serially sectioned implanted temporal bones has provided insight into what is being stimulated; and the changes that are the result of the insertion and presence of the implant. The ganglion cell bodies (neurons) are structures being stimulated (two laboratories have reported an inverse relationship of the number of neurons and performance). Insertion through the round window, verses a cochleostomy, produces the least fibrosis and new bone. Fibrosis and new bone do not affect the implant function unless they form in the scala vestibuli in the region of the ductus reuniens, and, block it; and produce cochlear hydrops resulting in a delayed low tone loss of hearing in hybrid implants...

The transition from intrauterine to extrauterine life represents a critical phase of physiological adaptation which impacts many organ systems, most notably the heart and the lungs. The majority of term neonates complete this transition without complications; however, dysregulation of normal postnatal adaptation may lead to acute cardiopulmonary instability, necessitating advanced intensive care support. Although not as well appreciated as changes in vascular resistances, the shunt across the DA plays a crucial physiologic role in the adaptive processes related to normal transitional circulation...

Preterm birth is the major challenge in obstetrics affecting ~10% of pregnancies. Pan-prostaglandin synthesis inhibitors (NSAID) prevent preterm labor and prolong pregnancy but raise concerns about fetal renal and cardiovascular safety. We conducted preclinical studies examining the tocolytic effect and fetal safety of the oral prodrug candidate OBE022 and its parent OBE002, both potent and highly selective antagonist of the contractile PGF2α prostaglandin receptor (FP). Efficacy of OBE022 and OBE002, alone and in combination with other tocolytics, was assessed in human tissues and pregnant animal models for inhibition of uterine contraction and delay of parturition...

Congenital heart defects (CHD) are structural malformations found at birth with a prevalence of 1%. The clinical trajectory of CHD is highly variable and thus in need of robust diagnostics and therapeutics. Major surgical interventions are often required for most CHDs. In Africa, despite advances in life sciences infrastructure and improving education of medical scholars, the limited clinical data suggest that CHD detection and correction are still not at par with the rest of the world. But the toll and genetics of CHDs in Africa has seldom been systematically investigated...

The patient was a 66 year-old male. Computed tomography (CT) angiography showed a huge aneurysm(120 mm) in the aortic arch and chronic type B aortic dissection(45 mm) in the descending aorta. Echocardiography showed patent ductus arteriosus( PDA). Because of pulmonary hypertension due to PDA, it was considered unacceptable to put him under general anesthesia twice. We performed thoracic endovascular aortic repair (TEVAR) via the ascending aorta and total arch replacement (TAR) simultaneously to prevent paraplegia...

OBJECTIVES: The correct ductus arteriosus (DA) closure time is somewhere between the opening and closing time confirmed on echo, not on examination. We investigated DA closure time and factors affecting DA closure time using interval censoring analysis. METHODS: This was an observational, retrospective study including 2611 healthy neonates. Echo was performed every 12-24 h after birth until DA closure. We investigated the DA closure time using interval censoring analysis...

REVIEW
Karel Maršál
The growth-restricted fetus in utero is exposed to a hostile environment and suffers undernutrition and hypoxia. To cope with the stress, the fetus changes its physiological functions. These adaptive changes aid intrauterine survival; however, they can lead to permanent functional and structural changes that can contribute to the development of serious chronic diseases later in life. Epigenetic mechanisms are an important part of the pathophysiological processes behind this "developmental origin of adult diseases...

INTRODUCTION: Despite adequate glycemic control, the risks of fetal macrosomia and perinatal complications are increased in diabetic pregnancies. Adjustments of the umbilical venous (UV) distribution, including increased ductus venosus (DV) shunting, can be important fetal compensatory mechanisms, but the impact of pregestational diabetes on UV and DV flow is not known. MATERIAL AND METHODS: In this prospective study, 49 women with pregestational diabetes mellitus underwent monthly ultrasound examinations from gestational week 20 to 36...

BACKGROUND: Cardiovascular disease (CVD) presents the most serious health problems and contributes to the increased mortality in young women with Turner syndrome. Arterial hypertension in Turner syndrome patients is significantly more prevalent than that in a general age-matched control group. The aetiology of hypertension in Turner syndrome varies, even in the absence of cardiac anomalies and obvious structural renal abnormalities. Pheochromocytoma is an extremely rare cause among various etiologies for hypertension in patients with Turner syndrome...

Interrupted aortic arch (IAA) is defined as the loss of luminal continuity between the ascending and descending aorta and is classified based on the anatomic level of interruption. IAA is associated with a number of intracardiac anomalies with the most common being patent ductus arteriosus, ventricular septal defect, and left ventricular outflow obstruction. There is also a strong association between type B interruption and 22q11 deletion syndrome. The perioperative management of the neonate with IAA begins in the intensive care unit with optimization of end-organ perfusion and function...

BACKGROUND: Necrotizing enterocolitis (NEC) is a serious complication of prematurity. Our objective was to evaluate the impact of an umbilical cord milking protocol (UCM) and pasteurized donor human milk (PDHM) on NEC rates in infants less than 30 weeks gestational age from January 1, 2010 to September 30, 2016. We hypothesized an incremental decrease in NEC after each intervention. METHODS: We performed a retrospective review of 638 infants born less than 30 weeks gestational age...

Three entire, domestic, shorthair male cats (age range: 3 months to 5 years) were referred because of regurgitation. Megaoesophagus attributable to aberrant right subclavian artery, originating from the aorta at the level of the fourth intercostal space, was diagnosed in all cats using thoracic radiography and CT angiography. One cat had concurrent patent ductus arteriosus with a normal aortic arch. Three-dimensional volume-rendered CT images were used to assess the malformations and to plan surgery for the treatment of the vascular anomalies...

REVIEW
M Kluckow, P Lemmers
Assessment and management of a patent ductus arteriosus (PDA) in premature infants remains problematic. The more immature the infant, the more likely a PDA is to be present, due to lower spontaneous PDA closure rates. Clinicians now recognize that not all PDAs require treatment and that selection of the group of infants with a more hemodynamically relevant PDA, often manifesting as an increasing systemic-to-pulmonary shunt, is increasingly important. Ultrasound is the mainstay of diagnosis and physiological assessment of the PDA; however, there are other methodologies used to assess hemodynamic importance of the PDA...

BACKGROUND: Initial resuscitation with air is well tolerated by most infants born at term. However, the optimal fractional inspired oxygen concentration (FiO2 - proportion of the breathed air that is oxygen) targeted to oxygen saturation (SpO2 - an estimate of the amount of oxygen in the blood) for infants born preterm is unclear. OBJECTIVES: To determine whether lower or higher initial oxygen concentrations, when titrated according to oxygen saturation targets during the resuscitation of preterm infants at birth, lead to improved short- and long-term mortality and morbidity...

OBJECTIVES: To describe the perinatal outcomes of type II and III selective fetal growth restriction (sFGR) in monochorionic-diamniotic (MCDA) twin pregnancies treated with expectant management or laser ablation of placental vessels (LAPV). METHODS: Retrospective analysis of cases of sFGR that received expectant management (type II, n=6; type III, n=22) or LAPV (type II, n=30; type III, n=9). The main outcomes were gestational age at delivery and survival rate. RESULTS: The smaller fetus presented an absent/reversed "a" wave in the ductus venosus (arAWDV) in all LAPV cases, while none of the expectant management cases presented arAWDV...
