Benign infantile convulsions with mild gastroenteritis: clinical analysis of 40 cases / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate the pathogenesis, clinical characteristics and treatment of benign infantile convulsions with mild gastroenteritis (BICG).</p><p><b>METHODS</b>The clinical manifestations and laboratory findings were observed in 40 children with BICG. The antigen and antibodies of rotavirus and calicivirus in stool and cerebral spinal fluid (CSF) were tested by the golden standard method and ELISA. The neurological outcome was evaluated by a follow-up of six months or more.</p><p><b>RESULTS</b>All of the 40 children had mild gastroenteritis with or without minor dehydration. Cluster convulsions were observed in these children. There were normal findings in blood biochemistry (Na+, K+, Ca2+, Cl-, HCO3-, glucose) and cerebral CT or MRI examinations. The interictal EEG showed sprinkle central or frontal epileptiform discharges in 8 children; clear central and parietal epileptiform discharges in 1 child; and no abnormal findings were observed in the other 31 children. Positive rotavirus antigen was detected in 11 children and positive calicivirus antigen in stool samples in 4 children. Positive antibodies of rotavirus and calicivirus in CSF were not seen. Seizures recurred in 22 of 28 children who received prophylactic injections of phenobarbital(5-10 mg/kg). In a 6 months follow-up, one child developed epilepsy and the other 39 children had no seizures and neurological sequelae.</p><p><b>CONCLUSIONS</b>The digestive system manifestations are mild in children with BICG. Convulsions are always clustered in these children. The mechanism underlying convulsions is not clear. Conventional dose of phenobarbital is not effective for prevention of seizures. Most of children with BICG have a good prognosis.</p>

Interictal epileptiform discharges in children with epilepsy / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the features of interictal epileptiform discharges (IED) during sleep and wakefulness in children with epilepsy.</p><p><b>METHODS</b>The polysomnography, active EEG and video EEG were performed on 48 children with epilepsy during the whole night, and wakefulness of pre- and post-sleep. The epileptiform sharp/spike discharge indexes during sleep and wakefulness were recorded. The positive rate of IED in focal and generalized epilepsy was compared.</p><p><b>RESULTS</b>Of the 48 patients, 25 showed IED, including 9 cases (36.0%) in the generalized seizure group and 16 cases (64.0%) in the focal seizure group (P<0.05). The epileptiform sharp/spike discharge indexes in the whole non-rapid eye movement (NREM) sleep stage (stages S1-S4: 21.13+/-19.96, 19.59+/-17.76, 22.85+/-18.99, and 20.37+/-16.63) were significantly higher than that in the wakefulness stage (8.20+/-6.21) (P<0.05). The discharge index in the S3 stage during NREM sleep was higher than that during the rapid eye movement (REM) sleep (22.85+/-18.99 vs 12.91+/-10.95; P<0.05).</p><p><b>CONCLUSIONS</b>The positive rate of IED in the focal seizure group was higher than that in the generalized seizure group. Sleep, especially NREM sleep, facilitates IED in children with epilepsy.</p>

Behavior Characteristics in Children with Benign Epilepsy Combined with Centro-Temporal Spikes / 实用儿科临床杂志

Objective To explore the behavior characteristics in children with benign epilepsy combined with centro-temporal spikes(BECTS).Methods Eighty-two children with BECTS aged 2.5-3.0(2.65?2.31)years old,51 male,31 female,who were free of mental retardation assessed with Gesell developmental schedules,untreated with antiepileptic drugs,and were investigated 15 days after the latest seizure.Eighty-two healthy children with sex and age matched to the cases,53 male,29 female,aged 2.5-3.0(2.6?0.4)years old.The behavior characteristics of infants in BECTS group and control group were assessed with CBCL,including 6 behavior factors which were sleep problem,social flinches,depression,physical aspect,attacking,act of sabotage and the infants-middle school student social ability scale.Results The total scores of behavior characteristics and the scores of depression,sleep problem,attacking and act of sabotage in BECTS group were all higher than those in control group,the differences were statistically significant.However,scores of social flinches,and physical aspect in BECTS group had no significant differences compared with those of control group.There were no significant difference of social adaptive component between the BECTS and control group.Conclusions Children with BECTS have behavior disorders to some extent,but their social adaptive capacity are the same as normal children.
