OBJECTIVE: To determine the cumulative incidence and clinical predictors of remote symptomatic seizures and epilepsy after pediatric arterial ischemic stroke (AIS). METHODS: We performed a retrospective analysis of 218 participants with neonatal AIS (NAIS), presumed perinatal AIS (PPAIS), and childhood AIS (CAIS) from a single-center prospective consecutive cohort enrolled from 2006 to 2014. Medical records were reviewed for timing, semiology, and treatment of acute symptomatic seizures, remote symptomatic seizures (RSS), and epilepsy...

Global developmental delay (GDD), often accompanied by intellectual disability, seizures and other features is a severe, clinically and genetically highly heterogeneous childhood-onset disorder. In cases where genetic causes have been identified, de-novo mutations in neuronally expressed genes are a common scenario. These mutations can be best identified by exome sequencing of parent-offspring trios. De novo mutations in the guanine nucleotide-binding protein, beta 1 (GNB1) gene, encoding the Gβ1 subunit of heterotrimeric G proteins, have recently been identified as a novel genetic cause of GDD...

Congenital Muscular Dystrophies (CMDs) can be considered as a heterogeneous group of diseases characterized by marked weakness, generalized hypotonia and joint contractures. They are divided into pure and classical forms, without ocular and cerebral involvement, and complex forms, which are associated with cerebral abnormalities. Seizures have rarely been described in the pure forms while they seem to occur more frequently in complex forms. The aim of our study was to evaluate the incidence of seizure in CMD...

Background Coagulopathy is a major problem in surgery for cyanotic congenital heart disease. Tranexamic acid has been used both topically and systemically and plays a vital role in pediatric cardiac surgery by reducing blood loss and blood product requirement. We aimed to determine the anti-fibrinolytic effectiveness of low-dose systemic or topical tranexamic acid or a combination of both. Methods Seventy-five patients were divided in 3 groups of 25. Group A patients were given tranexamic acid 20 mg kg(-1) intravenously after sternotomy and 20 mg kg(-1) after heparin reversal...

BACKGROUND: The severity of the initial encephalopathy in neonatal hypoxic-ischemic encephalopathy correlates with seizure burden. Early electroencephalograph (EEG) background activity reflects the severity of encephalopathy. Thus, we hypothesized that early EEG background would be predictive of subsequent seizures in neonatal hypoxic-ischemic encephalopathy. METHODS: This study included infants undergoing therapeutic hypothermia at St. Louis Children's Hospital between January 2009 and April 2013...

Crucial to the success of epilepsy surgery is the availability of a robust biomarker that identifies the Epileptogenic Zone (EZ). High Frequency Oscillations (HFOs) have emerged as potential presurgical biomarkers for the identification of the EZ in addition to Interictal Epileptiform Discharges (IEDs) and ictal activity. Although they are promising to localize the EZ, they are not yet suited for the diagnosis or monitoring of epilepsy in clinical practice. Primary barriers remain: the lack of a formal and global definition for HFOs; the consequent heterogeneity of methodological approaches used for their study; and the practical difficulties to detect and localize them noninvasively from scalp recordings...

BACKGROUND: Growing skull fractures (GSFs) are rare complications of pediatric head trauma that comprise skull fractures associated with an underlying dural tear and an intact arachnoid membrane. They are often misdiagnosed, and delay in management can lead to progression of the disease along with its neurological sequelae. Multiple clinical reports and qualitative reviews on this entity exist. To our knowledge, this represents the largest clinical review reporting on established techniques in the management of these fractures...

PURPOSE: To identify risk factors for the development of epilepsy after pediatric stroke. METHODS: Retrospective analysis of hospital charts of 93 children and adolescents with post-neonatal non-traumatic stroke and a minimum follow-up of two years. Seizures during the first 48 h after onset of stroke symptoms were defined as "early seizures"; when two or more seizures occurred after this period, the patient was classified as "epileptic". RESULTS: Early seizures, young age at stroke and MRI evidence of cortical involvement were observed more frequently in the children who developed epilepsy...

BACKGROUND/PURPOSE: Pediatric epilepsy caused by a KCNQ2 gene mutation usually manifests as benign familial neonatal seizures (BFNS) during the 1(st) week of life. However, the exact mechanism, phenotype, and genotype of the KCNQ2 mutation are unclear. METHODS: We studied the KCNQ2 genotype from 75 nonconsanguineous patients with childhood epilepsy without an identified cause (age range: from 2 days to 18 years) and from 55 healthy adult controls without epilepsy...

Anti-N-methyl D-aspartate receptor (anti-NMDAR) encephalitis, recently recognized as a form of paraneoplastic encephalitis, is characterized by a prodromal phase of unspecific illness with fever that resembles a viral disease. The prodromal phase is followed by seizures, disturbed consciousness, psychiatric features, prominent abnormal movements, and autonomic imbalance. Here, we report a case of anti-NMDAR encephalitis with initial symptoms of epilepsia partialis continua in the absence of tumor. Briefly, a 3-year-old girl was admitted to the hospital due to right-sided, complex partial seizures without preceding febrile illness...

Pediatric epilepsy can be caused by various conditions, including specific syndromes. 1p36 deletion syndrome is reported in 1 in 5,000-10,000 newborns, and its characteristic clinical features include developmental delay, mental retardation, hypotonia, congenital heart defects, seizure, and facial dysmorphism. However, detection of the terminal deletion in chromosome 1p by conventional G-banded karyotyping is difficult. Here we present a case of epilepsy with profound developmental delay and characteristic phenotypes...

PURPOSE: To review the epidemiology, clinical features, and treatment of seizures secondary to pediatric brain tumors. METHOD: Literature review. RESULTS: Pediatric brain tumors are the most common solid pediatric tumor and the most common cause of death in pediatric cancer. Seizures are one of the most common symptoms of pediatric brain tumors. Factors associated with increased risk of seizures include supratentorial location, gray matter involvement, low-grade, and certain histological features-especially dysembryoplastic neuroepithelial tumor, ganglioglioma, and oligodendroglioma...

Transcranial direct current stimulation (tDCS) is a neuromodulatory noninvasive brain stimulation tool with potential to increase or reduce regional and remote cortical excitability. Numerous studies have shown the ability of this technique to induce neuroplasticity and to modulate cognition and behavior in adults. Clinical studies have also demonstrated the ability of tDCS to induce therapeutic effects in several central nervous system disorders. However, knowledge about its ability to modulate brain functions in children or induce clinical improvements in pediatrics is limited...
