ObjectiveThis clinical study is aimed to investigate whether levetiracetam (LEV) can improve electrocorticogram (EEG) in epileptic children epilepsy patients with better clinical manifestation but abnormal EEG findings.MethodsTotally 39 children from our neurological clinic with partial or complex partial epilepsy seizure were included in present study and assigned equally into three groups receiving different treatment:control group,sodium valproate (VPA) group,and LEV group.Their clinical symptoms had been controlled for over one year by carbamazepine ( CBZ),but EEG results showed clearly abnormal.Epileptiform discharges were observed in routine EEG exams half a month before recruiting.After recruiting,they continued to receive CBZ alone (control group) or co-treated with VPA ( VPA group) or LEV (LEVgroup),respectively.Six months later,EEG was taken again and results were analyzed.ResultsImprovement rate were 9.1％ ( control group),23.1％ ( VPA group),and 66.7％ (LEV group),respectively;Overall statistical difference was reached among three groups ( P＜0.01 ) and between control group and LEV group( P＜0.012 5 ),but no statistical difference between control group and VPA group was reached ( P＞0.0125).ConclusionCo-treatment of LEV in child epilepsy patients receiving CBZ can significantly decrease abnormal EEG discharge frequency during interictal period.

Objective To explore the common pathogen of infantile convulsions associated with mild gastroenteritis, and to study the differences between the seizures caused by the two kinds of virus.Methods RT-PCR was used to detect Rotavirus (RV) and Norwalkvirus (NoV) in stool and cerebrospinal fluid of 30 cases with infantile convulsions associated with mild gastroenteritis. The differences between the frequency of seizures caused by two kinds of virus were analyzed by statistical methods (two-sample t-test).Results 17/30 (56. 7%) were RV-positive in stool and 3/17 (17. 7%) in cerebrospinal fluid; 6/30 (25.0%) were NoV-positive in stool and 1/6 (16. 7%) in cerebrospinal fluid. The seizure frequency with NoV infection was (4. 33 ± 1.75) times, and RV infection patients was (2. 53 ± 1.12) times (P ＜ 0. 01).The seizure frequency of CSF virus-positive children was (4. 75 ± 1.71) times compared to (2. 63 ± 1.21)times in virus-negative children (P ＜ 0.01). Conclusion The common pathogens causing infantile convulsions associated with mild gastroenteritis were RV and NoV. The degree of NoV infection affecting the central nervous system may be greater than RV. The presence of the virus in cerebrospinal fluid may lead to higher incidence of seizures,but their exact roles related to the occurrence of seizures remain to be further studied.
