Cell Death Dis 2019 Apr 11;10(4):325. Epub 2019 Apr 11.

Department of Pathology, Yale University School of Medicine, New Haven, CT, USA.

Neonatal hypoxic injury (NHI) is a devastating cause of disease that affects >60% of babies born with a very low birth weight, resulting in significant morbidity and mortality, including life-long neurological consequences such as seizures, cerebral palsy, and intellectual disability. Hypoxic injury results in increased neuronal death, which disrupts normal brain development. Although animal model systems have been useful to study the effects of NHI, they do not fully represent the uniqueness and complexities of the human brain. Read More

How Early Can a Seizure Happen? Pathophysiological Considerations of Extremely Premature Infant Brain Development.

Dev Neurosci 2019 Apr 4:1-20. Epub 2019 Apr 4.

Division of Pediatric Neurology, Department of Neurology, The Johns Hopkins University School of Medicine, Baltimore, Maryland, USA,

Seizures in neonates represent a neurologic emergency requiring prompt recognition, determination of etiology, and treatment. Yet, the definition and identification of neonatal seizures remain challenging and controversial, in part due to the unique physiology of brain development at this life stage. These issues are compounded when considering seizures in premature infants, in whom the complexities of brain development may engender different clinical and electrographic seizure features at different points in neuronal maturation.

Argininosuccinate neurotoxicity and prevention by creatine in argininosuccinate lyase deficiency: An in vitro study in rat three-dimensional organotypic brain cell cultures.

J Inherit Metab Dis 2019 Mar 25. Epub 2019 Mar 25.

Service of Clinical Chemistry, Lausanne University Hospital and University of Lausanne, Switzerland.

The urea cycle disorder (UCD) argininosuccinate lyase (ASL) deficiency, caused by a defective ASL enzyme, exhibits a wide range of phenotypes, from life-threatening neonatal hyperammonemia to asymptomatic patients, with only the biochemical marker argininosuccinic acid (ASA) elevated in body fluids. Remarkably, even without ever suffering from hyperammonemia, patients often develop severe cognitive impairment and seizures. The goal of this study was to understand the effect on the known toxic metabolite ASA and the assumed toxic metabolite guanidinosuccinic acid (GSA) on developing brain cells, and to evaluate the potential role of creatine (Cr) supplementation, as it was described protective for brain cells exposed to ammonia.

Maternal Noninfectious Fever Enhances Cell Proliferation and Microglial Activation in the Neonatal Rat Dentate Gyrus.

Anesth Analg 2019 Mar 11. Epub 2019 Mar 11.

Department of Anesthesiology, Tufts Medical Center, Boston, Massachusetts.

Background: Fever and increased maternal interleukin-6 (IL-6) plasma levels in labor are associated with an increased risk of adverse events in offspring, including neonatal seizures, cerebral palsy, and low intelligence scores at school age. However, the neural changes in the neonate that might mediate the adverse effects of maternal noninfectious fever are not fully characterized. This study was designed to test the hypothesis that induced maternal noninfectious fever alters neonatal neural progenitor cell proliferation and enhances microglial activation in the rat dentate gyrus of the hippocampus.

With a birth-prevalence of 37-67/100,000 (mostly term-born), perinatal stroke encompasses distinct disease-states with diverse causality, mechanism, time of onset, mode of presentation and outcome. Neonatal primary haemorrhagic stroke and ischemic events (also divided into neonatal arterial ischemic stroke and neonatal cerebral sinus venous thrombosis) that manifest soon after birth are distinguished from presumed perinatal - ischemic or haemorrhagic - stroke. Signs of the latter become apparent only beyond the neonatal period, most often with motor asymmetry or milestones delay, and occasionally with seizures. Read More

Seizure Susceptibility Correlates with Brain Injury in Male Mice Treated with Hypothermia after Neonatal Hypoxia-Ischemia.

Dev Neurosci 2019 Feb 28:1-10. Epub 2019 Feb 28.

Department of Neurology, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA.

Hypoxic-ischemic encephalopathy is a common neonatal brain injury associated with significant morbidity and mortality despite the administration of therapeutic hypothermia (TH). Neonatal seizures and subsequent chronic epilepsy are frequent in this patient population and current treatments are partially effective. We used a neonatal murine hypoxia-ischemia (HI) model to test whether the severity of hippocampal and cortical injury predicts seizure susceptibility 8 days after HI and whether TH mitigates this susceptibility.

Practice variation in anti-epileptic drug use for neonatal hypoxic-ischemic encephalopathy among regional NICUs.

BMC Pediatr 2019 Feb 27;19(1):67. Epub 2019 Feb 27.

Children's National Health Systems, Washington, DC, USA.

Background: While intercenter variation (ICV) in anti-epileptic drug (AED) use in neonates with seizures has been previously reported, variation in AED practices across regional NICUs has not been specifically and systematically evaluated. This is important as these centers typically have multidisciplinary neonatal neurocritical care teams and protocolized approaches to treating conditions such as hypoxic ischemic encephalopathy (HIE), a population at high risk for neonatal seizures. To identify opportunities for quality improvement (QI), we evaluated ICV in AED utilization for neonates with HIE treated with therapeutic hypothermia (TH) across regional NICUs in the US. Read More

Further corroboration of distinct functional features in SCN2A variants causing intellectual disability or epileptic phenotypes.

Mol Med 2019 02 27;25(1). Epub 2019 Feb 27.

Institute of Medical Genetics, University of Zurich, 8952, Schlieren, Zurich, Switzerland.

Background: Deleterious variants in the voltage-gated sodium channel type 2 (Na1.2) lead to a broad spectrum of phenotypes ranging from benign familial neonatal-infantile epilepsy (BFNIE), severe developmental and epileptic encephalopathy (DEE) and intellectual disability (ID) to autism spectrum disorders (ASD). Yet, the underlying mechanisms are still incompletely understood. Read More

Seizures in the newborn are associated with high morbidity and mortality, making their detection and treatment critical. Seizure activity in neonates is often clinically obscured, such that detection of seizures is particularly challenging. Amplitude-integrated EEG is a technique for simplified EEG monitoring that has found an increasing clinical application in neonatal intensive care. Read More

Response to antiseizure medications in neonates with acute symptomatic seizures.

Epilepsia 2019 Mar 20;60(3):e20-e24. Epub 2019 Feb 20.

Department of Pediatrics, University of Michigan, Ann Arbor, Michigan.

In a prospective cohort of 534 neonates with acute symptomatic seizures, 66% had incomplete response to the initial loading dose of antiseizure medication (ASM). Treatment response did not differ by gestational age, sex, medication, or dose. The risk of incomplete response was highest for seizures due to intracranial hemorrhage and lowest for hypoxic-ischemic encephalopathy, although the difference was not significant after adjusting for high seizure burden and therapeutic hypothermia treatment.

A novel mutation in KCNQ3-related benign familial neonatal epilepsy: electroclinical features and neurodevelopmental outcome.

Epileptic Disord 2019 Feb;21(1):87-91

Department of Sciences for Health Promotion and Mother and Child Care "G. D'Alessandro," University of Palermo, Palermo.

Benign familial neonatal epilepsy (BFNE) is caused, in about 5% of families, by mutations in the KCNQ3 gene encoding voltage-gated potassium channel subunits. Usually, newborns with BFNE show a normal neurological outcome, but recently, refractory seizures and/or developmental disability have been reported suggesting phenotype variability associated with KCNQ3-related BFNE. Here, we describe a proband from a BFNE family carrying a novel variant in the KCNQ3 gene. Read More

Status Epilepticus in the Neonate: Updates in Treatment Strategies.

Curr Treat Options Neurol 2019 Feb 18;21(2). Epub 2019 Feb 18.

Division of Neurology, Department of Pediatrics, Nationwide Children's Hospital, Ohio State University, 611 E Livingston Avenue FB4, Columbus, OH, 43205, USA.

Purpose Of Review: The purpose of this review is to report recent advances in treatment of neonatal seizures, with a specific focus on new literature since a 2013 systematic review performed by this author (Slaughter) and others. There is a paucity of data with regard to well-defined status epilepticus (SE) in neonates, so treatment of recurrent seizures was also included in this inquiry. We aimed to summarize the efficacy and safety profiles of current therapeutic options as well as describe trends in medication selection in the neonatal intensive care unit (NICU) setting. Read More

Lestaurtinib (CEP-701) modulates the effects of early life hypoxic seizures on cognitive and emotional behaviors in immature rats.

Epilepsy Behav 2019 Mar 13;92:332-340. Epub 2019 Feb 13.

Department of Anatomy, Cell biology and Physiological Sciences, Faculty of Medicine, American University of Beirut, Beirut, Lebanon; Division of Child Neurology, Department of Pediatric and Adolescent Medicine, American University of Beirut Medical Center, Beirut, Lebanon. Electronic address:

Hypoxic encephalopathy of the newborn is a major cause of long-term neurological sequelae. We have previously shown that CEP-701 (lestaurtinib), a drug with an established safety profile in children, attenuates short-term hyperexcitability and tropomyosin-related kinase B (TrkB) receptor activation in a well-established rat model of early life hypoxic seizures (HS). Here, we investigated the potential long-term neuroprotective effects of a post-HS transient CEP-701 treatment. Read More

Combined Conventional and Amplitude-Integrated EEG Monitoring in Neonates: A Prospective Study.

J Child Neurol 2019 May 14;34(6):313-320. Epub 2019 Feb 14.

1 Division of Neurology, Children's Hospital of Eastern Ontario, University of Ottawa, Ottawa, Ontario, Canada.

Background/objective: Seizure monitoring via amplitude-integrated EEG is standard of care in many neonatal intensive care units; however, conventional EEG is the gold standard for seizure detection. We compared the diagnostic yield of amplitude-integrated EEG interpreted at the bedside, amplitude-integrated EEG interpreted by an expert, and conventional EEG.

Methods: Neonates requiring seizure monitoring received amplitude-integrated EEG and conventional EEG in parallel. Read More

Web medical information produces anxiety in parents of infants with suspected galactosemia.

Rev Environ Health 2019 Feb 12. Epub 2019 Feb 12.

Institute of Child Health - Inborn Errors of Metabolism, Hivon and Papadiamantopoulou, Athens, Attica, Greece.

Parents had already taken information about galactosemia from web medical pages because they were asked for a second blood sample from their infant suspected for the disease. All enzyme types of this disorder are diagnosed by neonatal screening perinatally and treated with a galactose (GAL) free diet. The most frequent information about the disease was mental retardation (100%), eye cataracts (100%) liver dysfunction (90. Read More

Reduction in Head Computed Tomography Ordering in Pediatric Emergency Patients: Effect of National Publication and Local Availability of Urgent Neurology Appointments.

Pediatr Emerg Care 2019 Mar;35(3):199-203

Department of Pediatrics, University of Mississippi Medical Center, Jackson, MS.

Objective: The objective of this study was to evaluate the effect of the Pediatric Emergency Care Applied Research Network (PECARN) blunt head trauma guidelines and implementation of urgent neurology follow-up (UNF) appointments on an observed decline in head computed tomography (CT) use for pediatric emergency department (PED) patients presenting with headache, seizure, and trauma.

Methods: Patients ages 0 to 18 years presenting to and discharged from an urban tertiary care PED with chief complaint of trauma, headache, and seizure between 2007 and 2013 were retrospectively included. The total number of head CTs obtained in the trauma, headache, and seizure groups was compared before and after the publication of the PECARN guidelines in 2009 and the implementation of urgent UNF within a week from PED discharge in 2011, respectively.
