There is currently increasing interest in identifying and classifying pediatric benign epilepsy syndromes and recently several new syndromes have been recognized. Benign epilepsy syndromes, by definition, occur in children with normal developmental history, respond well to therapy, and remit without sequelae. The large majority of children with benign epilepsy syndromes follow a truly benign course. The concept of benign epilepsy syndromes has, however, been challenged by the minority of patients who continue to have seizures despite therapy, develop new seizures after initial remission, or exhibit neuropsychological abnormalities. Without long-term follow-up, benignity can not be truly ascertained a priori. Thus it may be preferable to use the terms possible and probable before the name of a specific syndrome until such time that the diagnosis of a definite benign syndrome is confirmed on long-term follow-up. In this review of the pediatric benign localization-related epilepsy syndromes, we address the concept of benignity and the process of diagnosis of a benign epilepsy syndrome. In addition we review the epidemiology, clinical manifestations, EEG findings, work-up, diagnostic criteria, differential diagnosis, genetics, management and prognosis of benign infantile familial convulsions, benign partial epilepsy in infancy with complex partial seizures, benign partial epilepsy in infancy with secondarily generalized seizures, benign infantile convulsions associated with mild gastroenteritis, and benign infantile focal epilepsy with midline spikes and waves during sleep.

"Benign convulsions with mild gastroenteritis (CwG)" is recognized as a benign situation-related seizure. Neuroimaging studies usually do not reveal any abnormalities. We report MRI diffusion-weighted image (DWI) findings of two patients who were clinically diagnosed with CwG. DWI demonstrated a transient abnormality in the splenium of the corpus callosum. Although viral encephalitis or encephalopathy should be carefully differentiated in patients clinically diagnosed with CwG, frequent seizures might cause transient splenial abnormality in patients with CwG.

We review the types and causes of convulsive status epilepticus (CSE) in infants and young children in Japan, and discuss the current recommendations for the use of intravenous (IV) drugs in managing this condition, and report on our clinical experiences. There are prolonged or continuous CSE and clustered or intermittent CSE, and treatments are different between them. In Japan, fosphenytoin and IV preparation of lorazepam and phenobarbital are not available. Recently, midazolam and lidocaine (LDC) have been widely used, although neither of these drugs have official approval for the management of CSE. Febrile seizures and epilepsies are common causes of CSE in infants and young children in Japan, followed by benign infantile convulsions (BIC), convulsions with gastroenteritis (CwG), and acute encephalitis with refractory CSE and intractable epilepsy (AECSEE), which are familiar disorders in Japan. BIC and CwG frequently present with clustered CSE and do not respond to IV diazepam, but have an excellent response with oral carbamazepine or IV LDC. CSE in AECSEE requires control with barbiturate coma. The Research Committee on Clinical Evidence of Medical Treatment for Status Epilepticus in Childhood has developed a proposed guideline for the treatment of CSE in childhood in Japan by an evidence-based approach and consensus conference. Initial management of seizures should be attempted mainly with IV diazepam, the second-line treatment involves IV midazolam followed by IV phenytoin if seizures persist, and the third-line treatment requires barbiturate coma. However, our experience of 247 episodes of CSE in 77 patients, predominantly with chronic epilepsy, required different second-line treatments for prolonged CSE compared with clustered CSE: the former were treated with IV midazolam or pentobarbital, and the latter were given IV phenytoin or LDC. We propose modifications to the guideline for CSE that the second-line treatment is divided by prolonged CSE and clustered CSE, and that the procedures for brain protection and systemic management are added.

It is known that rotavirus gastroenteritis can accompany some neurological manifestations, including encephalitis/encephalopathy or seizures. However, the detailed pathogenesis involved has not been fully understood. To date, acute cerebellitis associated rotavirus gastroenteritis has not been previously reported, except for one case. Herein, we describe two cases of acute encephalitis/encephalopathy and concurrent cerebellitis, associated rotavirus gastroenteritis. Following vomiting and diarrhea, case 1 experienced convulsions and consciousness disturbance and case 2, transient loss of consciousness with eye deviation. After these symptoms subsided, cerebellar signs became evident and a brain MRI showed cerebellar involvement in both cases. Both cases showed speech disturbances, such as mutism, slow speech and dysarthria. In this report, we will discuss the possible pathogenesis of rotavirus associated acute encephalitis/encephalopathy and concurrent cerebellitis.

Benign convulsions associated with mild gastroenteritis (CwG) are a commonly observed disorder in Asia, especially in infants and seniors. Here, we describe a retrospective study about the clinical features of CwG in 62 children hospitalized at St. Mary's Hospital (Kurume City, Japan) between January 1, 2000 and March 31, 2006, and further evaluate the efficacies of various anticonvulsant treatments for patients with CwG due to either rotavirus or norovirus. Causative diarrheal viruses were detected in 71% of the fecal specimens tested; 30 patients were positive for rotavirus, nine patients were positive for norovirus, two patients were positive for sapovirus, two patients were positive for adenovirus, and one patient was positive for coxackievirus A4. The age of onset for patients with norovirus-positive CwG (16.7+/-2.7 months) was significantly lower than that of patients with rotavirus-positive CwG (23.0+/-8.7 months). The duration of the seizures due to norovirus infection (11.8+/-12.0 h) was significantly longer than that due to rotavirus infection (4.9+/-5.7 h). There were no significant differences between the two groups with regard to the results of blood chemistry analysis, including the concentrations of serum electrolytes, blood glucose levels, and liver function tests. In this preliminary study, the duration of seizures in patients with CwG due to norovirus that was treated with carbamazepine was significantly shorter than the duration of seizures in the patients treated with another anticonvulsant (phenobarbital). Further randomized controlled studies are required to clarify the efficacies of the various anticonvulsants for patients with CwG.

Human herpesvirus-6 (HHV-6) infection is common in infancy, and symptoms are usually mild. However, encephalitis and other neurologic complications have been reported. Primary HHV-6 infection has been rarely confirmed in the central nervous system. We studied 21 children with suspected HHV-6 infection, drawn from a prospective, large-scale study of neurologic infections in Finland. Human herpesvirus-6 polymerase chain reaction was performed on cerebrospinal fluid samples, and antibody tests were performed on serum and cerebrospinal fluid. We identified nine children, aged 3 to 24 months, who had HHV-6-specific nucleic acid in cerebrospinal fluid. Primary infection was confirmed by seroconversion of specific antibodies in six, whereas one had a fourfold increase, and one had a fourfold decrease, in the antibody titer supporting recent infection. Generalized and prolonged seizures appeared in six children, four had a rash, four had ataxia, and four had gastroenteritis. All but two had a high fever. At follow-up, four children had evident neurologic sequelae, ataxia, and developmental disability, and needed special education. Primary HHV-6 infection may invade the central nervous system, and can cause neurologic symptoms and potentially permanent disability in children aged <or=2 years. The possibility of HHV-6 infection must be considered when treating acutely ill children, and especially those with convulsions.

Rotavirus infection is a frequent cause of gastroenteritis in children and accounts for significant morbidity and mortality, especially in the developing world. Less well recognized is the association of rotavirus-induced central nervous system dysfunction, which has been associated with seizure, encephalopathy, and death. Symptoms may vary widely, however, and children can experience short afebrile convulsions as the only manifestation of rotavirus encephalopathy. We report 4 further cases of rotavirus-induced seizures with mild neurologic manifestations. The condition is reviewed and practical management strategies are suggested.

We evaluated the usefulness of intravenous lidocaine therapy for managing of status epilepticus (SE) during childhood in a retrospective multi-institutional study. Questionnaires were sent to 28 hospitals concerning patients admitted for SE who were managed with lidocaine, assessing patient characteristics, treatment protocols and efficacy. In 279 treated patients, 261 SE occurrences at ages between 1 month and 15 years were analyzed. SE was classified as showing continuous, clustered, or frequently repeated seizures. Considering efficacy and side effects in combination, the usefulness of lidocaine was classified into six categories: extremely useful, useful, slightly useful, not useful, associated with deterioration, or unevaluated. In 148 SE cases (56.7%), lidocaine was rated as useful or extremely useful. Multivariate analysis indicated lidocaine was to be useful in SE with clustered and frequently repeated seizures, and SE attributable to certain acute illnesses, such as convulsions with mild gastroenteritis. Efficacy was poor when SE caused by central nervous system (CNS) infectious disease. Standard doses (approximately 2mg/kg as a bolus, 2mg/kg/h as maintenance) produced better outcomes than lower or higher doses. Poor responders to the initial bolus injection of lidocaine were less likely to respond to subsequent continuous infusion than good initial responders. We recommend lidocaine for use in SE with clustered or frequently repeated seizures, and in SE associated with benign infantile convulsion and convulsions with mild gastroenteritis. Lidocaine should be initiated with a bolus of 2mg/kg. If SE is arrested by the bolus, continuous maintenance infusion should follow; treatment should proceed to different measures when SE shows a poor response to the initial bolus of lidocaine.

This study assessed the validity of cerebrospinal fluid oxidative status of pediatric patients with central nervous system diseases, using the Diacron-Reactive Oxygen Metabolites test (d-Roms; Diacron International s.r.l.; Grosseto, Italy). Eighty-seven pediatric patients (8 with bacterial meningitis, 18 with aseptic meningitis, 23 with febrile seizures, 6 with rotavirus gastroenteritis-induced convulsions, 16 with epilepsy, 2 with adrenoleukodystrophy, 2 with multiple sclerosis, and 12 control subjects) were enrolled. An analysis of the infection-associated group (bacterial meningitis, aseptic meningitis, febrile seizures, and rotavirus gastroenteritis-induced convulsions) indicated that cerebrospinal fluid Diacron-Reactive Oxygen Metabolite levels in the bacterial meningitis group were significantly higher than in other infection-associated groups. In the bacterial meningitis group, the cerebrospinal fluid Diacron-Reactive Oxygen Metabolite levels obtained after improvement were significantly decreased compared with pre-improvement values. In the noninfection-associated group (epilepsy, adrenoleukodystrophy, and multiple sclerosis), the cerebrospinal fluid Diacron-Reactive Oxygen Metabolite levels in symptomatic epilepsy patients were higher than in cryptogenic epilepsy patients and control subjects, but not significantly. Progressive patients with adrenoleukodystrophy or multiple sclerosis demonstrated high Diacron-Reactive Oxygen Metabolite levels compared with another early-stage adrenoleukodystrophy patient. Oxidative stress may be associated with the pathogenesis of various pediatric central nervous system diseases. Cerebrospinal fluid Diacron-Reactive Oxygen Metabolite levels may correlate with clinical status in these diseases.
