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.

Rotavirus can cause seizures and encephalopathy in infants and young children. We report reversible EEG abnormalities in a 2 year and 7 month old boy who had a single seizure during rotavirus gastroenteritis. His EEG showed bilateral independent temporoparietal sharp waves. The EEG was normal 10 days after the first EEG and the patient has been followed with no neurological sequelae. The EEG literature in children developing seizures secondary to rotavirus infection including ours suggest the involvement of mostly posterior cerebral areas. The localization and reversibility of the process can enlighten the pathophysiology underlying this disorder.

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.

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.

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.

Central pontine myelinolysis and extrapontine myelinolysis are rare complications of rapid correction of chronic hyponatremia. Central pontine myelinolysis is more common and more predictable in presentation. Extrapontine myelinolysis' presenting symptoms vary and may be as general as lethargy or altered mood. We report experience with a patient who developed only extrapontine myelinolysis after rapid correction of severe hyponatremia associated with gastroenteritis. His presenting sign, generalized seizures, has not been previously reported. We summarize risk factors for myelinolysis, which may be more common than previously thought, as well as steps to minimize risk while managing vulnerable patients.

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.

Afebrile seizures in association with acute gastroenteritis without electrolyte disturbances have been reported in children from Asiatic countries, but only few references are from Spain. It is a benign, self-limiting process, with no specific examinations or therapy needed. There is no increased risk of epilepsy or impaired neurodevelopment in the children affected. We present five children with seizures during acute gastroenteritis admitted to Hospital Universitari Arnau de Vilanova of Lleida (Spain) between December 2005 and March 2006, during the last seasonal rotavirus outbreak. Patients with febrile seizures, electrolyte disturbances or previous seizures have been excluded. Association between acute gastroenteritis and afebrile benign seizures is also common in our setting, and some cases associated to seasonal rotavirus outbreaks have been published. All papers agree with the good prognosis of this problem. To consider this diagnosis is important in order avoid unnecessary examinations or anticonvulsive therapies.

The aim of this retrospective observational study was to evaluate age, length of hospital stay and development of complications in children hospitalized with community- or nosocomially- acquired rotavirus gastroenteritis (RV GE). In total, medical records of 984 children with RV GE were analysed retrospectively. The median age was 13.8 months (3 weeks to 99 months) in children with community acquired RV GE (n=723) and 9.0 months (range 3 weeks to 82 months) in children with nosocomially acquired RV GE (n=261). During this 11-y surveillance, only 2 children were admitted twice for a RV GE, suggesting development of subsequent protective immunity against severe rotavirus gastroenteritis after the first episode. Complications occurred in 16.5% of the children with community acquired RV GE and only in 1.9% of the nosocomially acquired RV GE. Identified complications in children with community acquired RV GE were: severe dehydration resulting in intensive care (1.7%), death (0.1%), hypertonic dehydration (9.1%), seizures (4.0%) and encephalitis with abnormal EEG (1.7%). The median age of children in need of intensive care was 9.1 months and in those developing hypertonic dehydration 10.8 months, both significantly lower than in children with no complications (p<0.05). Interestingly, the age of children developing seizures and signs of encephalitis was significantly higher than in children with no complications (p<0.01).
