Objective To observe the initial therapy outcomes of Valproic acid for childhood absence epilepsy (CAE),and to assess its therapeutic reaction and short-term prognosis,and to investigate the risk factors for initial therapy failure.Methods From January 2010 to December 2015,absence seizures as key words were used to search CAE in the video-electroencephalogram(VEEG) database of Children's Hospital Affiliated to Nanjing Medical University.Sixty-seven children fulfilled the CAE diagnosis criteria of International League Against Epilepsy in 1989.These patients were separated into 2 groups based on the therapy outcome after 6 months,including seizure control failure group and seizure control group.The patients' clinical characteristics and VEEG characteristics were reviewed.The gender,age of seizure onset,a family history of epilepsy or febrile seizures (FS),consistent with 2005 Panayiotopoulos diagnostic criteria,and VEEG findings were analyzed to evaluate the predictive ability of independent variables and the relationship between these features and treatment outcomes by using a stepwise multivariate Logistic regression model.Results The age at seizure onset was (5.89 ± 2.91) years old,and follow up duration was 6 months.Approximately 23 cases (34.3%) of CAE patients had poor response.No statistical correlation was made for gender,age at onset,the occurrence of generalized tonic clonic seizures,and family history of FS or epilepsy between 2 groups (all P >0.05).Compared with seizure control group,patients of the seizure control failure group had significantly higher rates of focal epileptic discharge (87.0% vs.6.8%),higher rates of intermittent photic stimulation (IPS) induced seizures (52.2% vs.6.8 %),fewer rates of occipital intermittent delta activity (8.7 % vs.77.3 %),and fewer rates of patients met the new diagnostic criteria proposed by Panayiotopoulos in 2005 (8.7% vs.88.6%) (all P < 0.001).The presence of occipital intermittent rhythmic delta activity during wake stage and the interictal focal epileptiform discharges on VEEG during sleep stage were significantly associated with the therapy outcomes in a multivariable Logistic regression analysis (OR =133.714,P < 0.05;OR =0.068,P < 0.05).Conclusions The presence of focal epileptiform discharges,and a typical absence induced by IPS are important factors for first-drug treatment failures with CAE,and conversely the occipital intermittent rhythmic delta activities have a good efficacy.There is no statistical correlation between clinical characteristics and treatment outcomes.

Objective To explore the effects of different courses of antenatal dexamethasone on brain development of premature SD rats. Methods The pregnant rats were randomly assigned to 3 groups: 3-dose dexamethasone (group 1), 1-dose dexamethasone group (group 2) and control group. The treated were sacrificed on 19 days of gestation, body and whole brain weight of the offspring rats were measured. Meanwhile the expression o{ neuron specific enolase (NSE) in brains of offspring rats was detected by immunohistochemical staining. The histological structures of baby rat brain were observed under transmission electron microscope. The differences among the three groups were analyzed by ANOVA. Results (1) The body and whole brain weight, the brain and body weight ratio were (1.543±0.052) g, (88.80±7.12) mg, and (5.75±0.38)% in group 1 and (1.584±0.035) g,(98.21±3.71) mg, and (6.20±0.26)% in group 2, both were lower than the control group [(1.696±0.076) g, (111.53±6.29) mg, (6.59±0.48)%], (P<0.01 or P<0.05, respectively). (2) The expression of NSE in cortex in group 1 and 2 were lower than that in control group (0.223±0.054, 0.381±0.041 vs 0.590±0.064) (P<0.01). The expression of NSE in hippocampi in group 1 and 2 were also lower than that in the control group (0.192±0.054, 0.359 ±0.046 vs 0.529±0.068) (P<0.01). (3) Disconnection of nuclei membrane, vacuolization in mitochondria, loss of nueleolus, and disconnection of neurofilaments were observed in the ultrastructure of baby rat brain tissue in both group 1 and 2. Conclusions Antenantal administration of dexamethasone can cause impairment of brain development in premature offspring rats and this might be related to the times of dexamethasone administered.
