To examine the origin of seizures induced by severe neonatal hyperbilirubinemia, The EEG characteristics of seizures were analyzed in newborns with and without severe neonatal hyperbilirubinemia. Fisher's exact test was used to determine the specificity. In total, 931 patients had a total serum bilirubin (TSB) level of 340-425 μmol/L, only 2 of whom had seizures. Compared to patients with hyperbilirubinemia and a TSB level of 340-425 μmol/L, those with a TSB level >425 μmol/L had a significant risk of seizure (OR = 213...

Midazolam is a drug belonging to the benzodiazepine group and is used commonly for seizure control as well as preoperative and procedure-related sedation in neonates. Many adverse effects of midazolam have been reported in the past. Paradoxical stimulation of the central nervous system such as restlessness, nightmare, and hallucinations as well as hypomanic behavior has been reported in adults and children. Seizure is a rare adverse effect of midazolam. Cases of myoclonic movements associated with midazolam have been published worldwide; however, none so far have been reported from India...

BACKGROUND: There is increasing evidence that neonatal seizures in term neonates with stroke, asphyxia or brain haemorrhage might be associated with adverse neurodevelopment and development of epilepsy. The extent of this association is not known. The objective of this study was to assess the possible impact of neonatal seizures on these outcomes and if possible calculate a relative risk. METHODS: A systematic review and meta-analysis was performed (study period January 2000-June 2015)...

Intracranial hemorrhage is an important cause of brain injury in the neonatal population and bedside percutaneous needle aspiration has emerged as an alternative due to the major risks that can be caused by standard neurosurgical decompression. We aimed to assess the effectiveness of this minimally invasive bedside technique and conducted a retrospective analysis of all newborn infants with a large extra-axial hemorrhage associated with a parenchymal hemorrhage causing a midline shift, managed at three academic centers over a 15-year period...

Zika virus (ZIKV) disease is a vector-borne infectious disease transmitted by Aedes mosquitoes. Recently, ZIKV has caused outbreaks in most American countries. Areas covered: Publications about neurological complications of ZIKV infection retrieved from pubmed searchers were reviewed, and reference lists and relevant articles from review articles were also examined. Vertical/intrauterine transmission leads to congenital infection and causes microcephaly and congenital ZIKV syndrome. ZIKV preferentially infects human neural progenitor cells and triggers cell apoptosis...

Congenital toxoplasmosis (CT) results from transplacental passage of Toxoplasma gondii to the fetus during acute maternal infection. Our study aims to report clinical and biological patterns of 35 cases of CT diagnosed at the department of the Parasitology of the Pasteur Institute of Tunis and to access the performance of prenatal and early postnatal diagnosis techniques. Serological screening of maternal infection was performed by Immunoglobulin (Ig) M and IgG detection and IgG avidity determination. Prenatal diagnosis was based on both Toxoplasma DNA detection in the amniotic fluid and monthly ultrasound examinations...

Epilepsy is a neurological disorder often associated with seizure that affects ∼0.7% of pregnant women. During pregnancy, most epileptic patients are prescribed antiepileptic drugs (AEDs) such as valproic acid (VPA) to control seizure activity. Here, we show that prenatal exposure to VPA in mice increases seizure susceptibility in adult offspring through mislocalization of newborn neurons in the hippocampus. We confirmed that neurons newly generated from neural stem/progenitor cells (NS/PCs) are integrated into the granular cell layer in the adult hippocampus; however, prenatal VPA treatment altered the expression in NS/PCs of genes associated with cell migration, including CXC motif chemokine receptor 4 ( Cxcr4 ), consequently increasing the ectopic localization of newborn neurons in the hilus...

Arterial spin labeling (ASL) magnetic resonance imaging (MRI) can assess cerebral blood flow (CBF) without using radiolabeled tracers. It is unknown whether regional increases in CBF on ASL MRI correlate with seizure location in newborns. We report 3 newborns with focal seizures localized on continuous video electroencephalogram (cEEG), anatomical brain MRI, and ASL MRI. Each patient underwent pseudocontinuous ASL with segmented 3-dimensional fast spin echo readout as part of standard care. Case 1 is a term male infant presenting with left temporal status epilepticus and recurrent cEEG seizures from an idiopathic large left intraventricular hemorrhage...

T-2 toxin is primarily produced by Fusarium sp. abundant under temperate climatic conditions. Its main harmful effect is the inhibition of protein synthesis. Causing oxidative stress, it also promotes lipid peroxidation and changes plasma membrane phospholipid composition; this may lead to nervous system alterations. The aim of the present study was to examine whether a single dose of T-2 toxin administered at newborn age has any long-lasting effects on nervous system functions. Rat pups were treated on the first postnatal day with a single intraperitoneal dose of T-2 toxin (0...

KEY POINTS: We evaluated the effect of magnesium sulphate (MgSO4 ) on seizures induced by asphyxia in preterm fetal sheep. MgSO4 did not prevent seizures, but significantly reduced the total duration, number of seizures, seizure amplitude and average seizure burden. Saline-asphyxia male fetuses had significantly more seizures than female fetuses, but male fetuses showed significantly greater reduction in seizures during MgSO4 infusion than female fetuses. A circadian profile of seizure activity was observed in all fetuses, with peak seizures seen around 04...

Pilocarpine-induced acute seizures strongly induce aberrant hippocampal neurogenesis, characterized by increased proliferation of neural progenitors and abnormal integrations of newly generated granule cells - hilar ectopic granule cells (EGCs), mossy fibre sprouting (MFS), and hilar basal dendrites (HBDs), which may disturb hippocampal neuronal circuits and thus contribute to cognitive impairment in temporal lobe epilepsy (TLE) patients and animal models. Previous studies via ablating hippocampal neurogenesis after acute seizures produced inconsistent results regarding the development of long-term cognitive impairment...

REVIEW

Seizures are more frequent in newborns than in any other period of life. In most cases they are due to acute dysfunction of the central nervous system; however some can be true epileptic disorders with an early onset. Although rare, diagnosis of neonatal-onset epilepsies is rising as genetic testing increases. The spectrum of clinical severity associated with specific genes can vary widely with difficulties in providing genotype-phenotype correlations. Therefore, clinicians should strive in order to clearly delineate the clinical features associated with pathogenic genetic variants with the aim to guide the increasing use of genetic testing and improve clinical management...

Approximately, 10-20% of newborns require breathing assistance at birth, which remains the cornerstone of neonatal resuscitation. Fortunately, the need for chest compression (CC) or medications in the delivery room (DR) is rare. About 0.1% of term infants and up to 15% of preterm infants receive these interventions, this will result in approximately one million newborn deaths annually worldwide. In addition, CC or medications (epinephrine) are more frequent in the preterm population (~15%) due to birth asphyxia...

Lena Hellström-Westas
The amplitude-integrated electroencephalogram (aEEG) is a filtered and compressed EEG trend that can be used for long-term monitoring of brain function in patients of all ages. aEEG is increasingly used in neonatal intensive care units since several studies have shown its utility in high-risk newborn infants. Main indications for aEEG monitoring include early evaluation of brain function after perinatal asphyxia and seizure detection. The aEEG is usually recorded from one or two channels derived from parietal, central, or frontal leads...

REVIEW
Francesco Pisani, Carlotta Spagnoli
Acute symptomatic neonatal seizures in preterm newborns are a relevant clinical challenge due to the presence of many knowledge gaps. Etiology-wise, acute symptomatic seizures have an age-specific epidemiology, with intraventricular hemorrhage and its complications representing the first cause in extremely and very preterm neonates, whereas other etiologies have similar occurrence rates as in full-term infants. Specific treatment strategies for the premature neonates are not yet available. Studies suggest a similarly low response rate with even more unfavorable prognosis than in full-term infants...
