BACKGROUND: Perinatal stroke is a common cause of established neurological sequelae. Although several risk factors have been identified, many questions regarding causes and clinical outcomes remain unanswered. This study investigated the clinical manifestations and outcomes of perinatal stroke and identified its etiologies in Taiwan. METHODS: We searched the reports of head magnetic resonance imaging and computed tomography performed between January 2003 and December 2012...

The patient is a 1-week-old boy born at 37+2 weeks' gestational age through spontaneous vaginal delivery. The pregnancy was complicated by maternal gestational diabetes mellitus and pre-eclampsia. The Apgar score was 9 at both 1 minute and 5 minutes after birth. Because of hypoglycemia at delivery that required IV dextrose, he was admitted to the local neonatal intensive care unit. His blood glucose levels quickly stabilized, dextrose administration was discontinued, and the patient began breast-feeding. On day 2 of life, the patient began having intermittent oxygen desaturation, with oxygen saturation as measured by pulse oximetry down to 70% while sleeping; he was transferred to a tertiary-care NICU for further management...

Neonatal hypoxia can lead to hippocampal atrophy, which can lead, in turn, to memory impairment. To test the generalisability of this causal sequence, we examined a cohort of 41 children aged 8-16, who, having received the arterial switch operation to correct for transposition of the great arteries, had sustained significant neonatal cyanosis but were otherwise neurodevelopmentally normal. As predicted, the cohort had significant bilateral reduction of hippocampal volumes relative to the volumes of 64 normal controls...

BACKGROUND: Myocardial tolerance to ischemia is influenced by age and preoperative cyanosis through unknown mechanisms and significantly affects postoperative outcomes. Cytochrome c oxidase (CcOx), the terminal enzyme of the mitochondrial electron transport chain, may play a role in the susceptibility to ischemic-reperfusion (IR) injury. Our study aimed at investigating changes in human myocardial CcOx activity based on age and preoperative oxygen saturation to understand its role in transition from neonatal to mature myocardium and hypoxic conditions...

Congenital heart block (CHB) is rare disorder that has a higher mortality when associated with structural congenital heart defects. Very few cases have been reported in Sub-Saharan Africa (SSA). We present a case of complete CHB associated with a complex congenital heart defect in a neonate in Cameroon. A 1-month-old neonate in Cameroon was referred for the evaluation of bradycardia. The obstetrical ultrasound done during pregnancy revealed fetal bradycardia without further evaluation. Clinical examination showed well a developed neonate with bradycardia at 62 beats/minute, and mild cyanosis with oxygen saturation at 93% at room air...

Crisscross heart is a rare cardiac malformation characterized by crossing of the inflow streams of the two ventricles due to a twisting of the heart about its long axis. The developmental mechanisms and causes of crisscross heart remain unknown. Neonates present with cyanosis and a systolic murmur. In this study, we report a case of crisscross heart with situs inversus, concordant atrioventricular and ventriculo arterial connection with ventricular septal defect and pulmonary stenosis, and review the literature on this rare cardiac malformation...

Major congenital or acquired heart disease in neonates presents with cyanosis, hypoxia, acute circulatory failure or cardiogenic shock. Antenatal diagnosis is made in up to 50% but heart disease is unanticipated in the remainder. The presence of significant heart disease in premature infants is also frequently not suspected at first; in general, whatever the underling cardiac anomaly, the clinical condition is worse, deteriorates more quickly and carries a poorer prognosis in premature and low birth weight infants...

Total anomalous pulmonary venous connection (TAPVC) is a potentially devastating form of congenital heart disease in which all pulmonary blood flow returns to the systemic venous circulation rather than the left atrium. Anomalous pulmonary venous flow may be obstructed at birth, and affected infants present with severe cyanosis and poor cardiac output unresponsive to standard resuscitation with prostaglandin. Obstructed TAPVC remains one of the few indications for emergent neonatal cardiac surgery. This review will discuss the physiology and perioperative management of isolated TAPVC without associated cardiac lesions...

INTRODUCTION: Neonatal respiratory distress (NRD) is a main cause of neonatal morbidity and mortality in developing countries. Early detection of its risk factors and early treatment of its etiologies are major challenges. However, few studies in developing countries have provided data needed to tackle it. We aimed to determine the prevalence, predictors, etiologies and outcome of NRD in a tertiary health care centre of Cameroon. METHODS: We analyzed the hospital files of all newborns admitted to the Neonatal unit of Douala General Hospital from 1(st) January 2011 to 28(th) February 2013...

Background. Neonatal deaths constitute the majority of child mortality in Vietnam, but studies are scarce and focus on community settings. Methods. During a 12-month period, all sick neonates admitted to a pediatric department in a province hospital were studied. Potential risk factors of death covering sociodemographic factors, pregnancy history, previous neonatal period, and status on admission were registered. The neonates were followed up until discharge or death or until 28 completed days of age if still hospitalized or until withdrawal of life support...

Neonatal cyanosis is rarely due to hemoglobin variants with low oxygen affinity. We describe the clinical course and results of molecular genetic analysis of a boy who presented after birth with severe cyanosis. Arterial blood-gas analysis demonstrated a pronounced shift of the oxygen-hemoglobin dissociation curve to the right and molecular genetic analysis revealed a γ-globin variant, Hb F-Sarajevo. The patient presented is the second reported case of neonatal cyanosis due to this mutation, which was first described in 2012 by Zimmermann-Baer and coauthors...

UNLABELLED: Nowadays appendicitis is the leading cause of acute surgical abdomen. It occurs mainly between the first and third decade of life and is very rare in the neonatal period. The pathophysiology and clinical manifestations differ from the typical signs and symptoms, making it difficult to diagnose, which is in mostly cases at the time of surgery, and 74% of them appear with perforation and peritonitis. During the first day there were no complications; however, antibiotic therapy was initiated due to the risk of sepsis...

BACKGROUND: Neonatal respiratory distress syndrome in preterm infants is a leading cause of neonatal death. Pulmonary insufficiency-related infant mortality rates have improved with antenatal glucocorticoid treatment and neonatal surfactant replacement. However, the mechanism of glucocorticoid-promoted fetal lung maturation is not understood fully, despite decades of clinical use. We previously have shown that genetic deletion of Erk3 in mice results in growth restriction, cyanosis, and early neonatal lethality because of pulmonary immaturity and respiratory distress...

Congenital heart disease is the most common form of all congenital malformations and, despite advances in prenatal and newborn screening, it may present undiagnosed to the emergency department. Signs and symptoms of congenital heart disease are variable and often nonspecific, making recognition and treatment challenging. Patient presentations can range from life-threatening shock or cyanosis in a neonate to respiratory distress or failure to thrive in infants. Advances in surgical techniques have improved short- and long-term survival of infants and children with congenital heart disease, but these children are at risk for a variety of complications related to the underlying or surgical anatomy and physiology...

Neonatal cyanosis resulting from a fetal methaemoglobin variant is rare. Most such variants are only described in a few published case reports. We present the case of a newborn with unexplained persistent cyanosis, ultimately determined to have a γ-chain mutation causing Hb FM-Fort Ripley. This neonatal haemoglobinopathy can be challenging to diagnose, as significant oxygen desaturation may result from barely detectable levels of the mutant haemoglobin and co-oximetry studies may show a falsely normal methaemoglobin level...

Congenital heart disease (CHD) increases the risk of adverse maternal and neonatal outcomes. However, previous studies have included mainly women with low-risk features. A single-center, retrospective analysis of pregnant women with CHD was performed. Inclusion criteria were the following high-risk congenital lesions and co-morbidities: maternal cyanosis; New York Heart Association (NHYA) functional class >II; severe ventricular dysfunction; maternal arrhythmia, single ventricle (SV) physiology, severe left-sided heart obstruction and severe pulmonary arterial hypertension...

Neonatal cyanosis is relatively common. It is usually a consequence of cyanotic heart disease or a pulmonary disorder, and warrants a thorough and quick investigation. Mutations causing decreased affinity of hemoglobin to oxygen may change α1 to β2 binding. We describe a new mutation (asp 102 serine), in the γ chain of hemoglobin, causing neonatal cyanosis which resolves as the baby matures. In this case we would like to emphasize the importance of early diagnosis in order to avoid unnecessary disease workup...
