BACKGROUND: Autism spectrum disorder (ASD), tic disorder (TD), and hyperkinetic syndrome of childhood (attention deficit disorder [ADD]/attention deficit hyperactivity disorder [ADHD]) are disorders recently defined as abnormal connectivity spectrum disorders (ACSDs) because they show a similar pattern of abnormal brain connectivity. This study examines whether these disorders are associated with exposure to thimerosal, a mercury (Hg)-based preservative. METHODS: A hypothesis testing case-control study evaluated the Vaccine Safety Datalink for the potential dose-dependent odds ratios (ORs) for diagnoses of ASD, TD, and ADD/ADHD compared to controls, following exposure to Hg from thimerosal-containing Haemophilus influenzae type b vaccines administrated within the first 15 months of life...

Since the nineteenth century several clinical features have been observed in common between migraine and epilepsy (such as episodic attacks, triggering factors, presence of aura, frequent familiarity), but only in recent years researchers have really engaged in finding a common pathogenic mechanism. From studies of disease incidence, we understand how either migraine among patients with epilepsy or epilepsy among migraine patients are more frequent than in the general population. This association may result from a direct causality, by the same environmental risk factors and/or by a common genetic susceptibility...

OBJECTIVE: Ketogenic diet is the first line therapy for neurological symptoms associated with pyruvate dehydrogenase deficiency (PDHD) and intractable seizures in a number of disorders, including GLUT1 deficiency syndrome (GLUT1-DS). Because high-fat diet raises serious compliance issues, we investigated if oral L,D-3-hydroxybutyrate administration could be as effective as ketogenic diet in PDHD and GLUT1-DS. METHODS: We designed a partial or total progressive substitution of KD with L,D-3-hydroxybutyrate in three GLUT1-DS and two PDHD patients...

BACKGROUND: Use and abuse of cocaine are associated with numerous adverse effects, independent of the route of administration. More severe conditions of poisoning, however, are observed after cocaine intravenous administration. AIM: We present a case of severe poisoning after violent intravenous injection of cocaine, but with a good outcome. CASE PRESENTATION: Cocaine was intravenously (i.v.) administered in 16-years old female patient as a homicide attempt...

It has been established that febrile seizures and its extended syndromes like generalized epilepsy with febrile seizures (FS) plus (GEFS+) and Dravet syndrome have been associated with mutations especially in SCN1A and GABRG2 genes. In patients, the onset of FS is likely due to the combined effect of temperature and inflammation in genetically vulnerable individuals because fever is often associated with infection. Much effort has been spent to understand the mechanisms underlying fever induction of seizures...

INTRODUCTION: Febrile convulsion (FC) is the most common neurological disorder in childhood. The aim of this study was to determine the risk factors for recurrence and the development of epilepsy from the demographic data of these patients. METHODS: A retrospective study was made of 680 patients with FC who presented to our hospital. Patients with only FC were defined as group 1 and those who developed epilepsy after FC as group 2. Comparisons were made between the 2 groups of the demographic parameters, parental consanguinity, familial history of FCs or epilepsy, criteria for starting prophylactic treatment, response to treatment, risk factors for recurrence, and results of electroencephalogram...

BACKGROUND: People with epilepsy who became seizure-free while taking antiepileptic drugs might consider discontinuing their medication, with the possibility of increased quality of life because of the elimination of adverse events. The risk with this action, however, is seizure recurrence. The objectives of our study were to identify predictors of seizure recurrence and long-term seizure outcomes and to produce nomograms for estimation of individualised outcomes. METHODS: We did a systematic review and meta-analysis, and identified eligible articles and candidate predictors, using PubMed and Embase databases with a last update on Nov 6, 2014...

Norovirus has become increasingly recognized as causing viral gastroenteritis in children. Few data are available on the characteristics of children admitted to pediatric emergency departments with norovirus gastroenteritis and accompanying seizures. Our aim in this study was to describe the clinical features of, and risk factors for, seizures accompanying norovirus gastroenteritis. We collected 6359 stool samples from patients with gastroenteritis, of whom 1444 (22.71%) had laboratory-confirmed norovirus gastroenteritis...

BACKGROUND: Dengue virus infection can have different complications; the best known is hemorrhagic dengue fever. However, other effects such as neurological disorders may endanger the lives of patients. Dengue neurological manifestations can be confused with encephalitis symptoms and can lead to cerebral edema and death. Therefore, we consider important in the endemic areas to take into account the diagnosis of dengue encephalitis in patients with neurological disorders, and to request the determination of serology in cerebrospinal fluid for the NS1 antigen test...

Pathogenic missense and truncating variants in the GABRG2 gene cause a spectrum of epilepsies, from Dravet syndrome to milder simple febrile seizures. In most cases, pathogenic missense variants in the GABRG2 gene segregate with a febrile seizure phenotype. In this case series, we report a recurrent, de novo missense variant (c0.316 G > A; p.A106T) in the GABRG2 gene that was identified in five unrelated individuals. These patients were described to have a more severe phenotype than previously reported for GABRG2 missense variants...

Protocadherin 19 (PCDH19)-related epilepsy (OMIM 300088) is a distinctive clinical syndrome limited to females. We describe a 17-year-old girl who presented to a regional epilepsy clinic with a history of recurrent febrile seizures in infancy. Genetic analysis of the PCDH19 gene revealed a novel heterozygous mutation within a highly conserved region of the gene. Patients with PCDH19 mutations present with clusters of seizures associated with fever. While fever-induced seizures are common to children with PCDH19 and SCN1A mutations, there are certain clinical features that distinguish these genetic syndromes from each other...

Because the differentiation between phenotypic expansion and blended phenotypes is not clear, the mixed phenotypes of blended rare genetic diseases make diagnosis difficult. We describe a family with the co-existence and co-segregation of generalized epilepsy with febrile seizures plus (GEFS+) and Kabuki syndrome (KS). The proband, a 7-year-old male, presented with GEFS+, dysmorphic facial features, short stature, developmental delay, and intellectual disability. Two novel missense mutations: p.G325A in the KDM6A gene responsible for KS and p...

Febrile infection-related epilepsy syndrome (FIRES) is a form of epileptic encephalopathy with severe refractory epilepsy that presents in previously healthy, school-aged children after significant febrile illness with concomitant rise in body temperature. Suspected causes include genetic or acquired channelopathies, as well as mitochondrial disturbances. In FIRES, the EEG shows diffuse slowing, generalized, and/or multifocal discharges. Seizures are present and resistant to treatment. Moyamoya angiopathy (MMA) is characterized by progressive stenosis of cerebral arteries and subsequent development of a network of collateral circulation that is prone to rupture...

BACKGROUND: Evidence for the beneficial effect of therapeutic burst-suppression coma in pediatric patients with febrile refractory status epilepticus is limited, and the clinical outcomes of this treatment strategy are largely unknown. Therefore, the aim of this study was to explore the outcomes of therapeutic burst-suppression coma in a series of children with febrile refractory status epilepticus. METHODS: We retrospectively reviewed consecutive pediatric patients with febrile refractory status epilepticus admitted to our pediatric intensive care unit between January 2000 and December 2013...

BACKGROUND: Febrile status epilepticus can have neurological sequelae. The type of sequelae, however, may depend on the etiology, including infections by viral agents such as the influenza virus. Respiratory syncytial virus (RSV) infection in childhood suggests a similar role for this pathogen. The aim of this study was to characterize febrile status epilepticus associated with RSV infection, and to determine whether this type of infection is a risk factor for neurological sequelae with febrile status epilepticus...
