ABSTRACT
Objective To evaluate the effect of vagus nerve stimulation (VNS)on post－encephalitic intrac-table epilepsy and the improvement of postoperative cognitive function and quality of life.Methods The patients with post－encephalitic epilepsy in Sanbo Brain Hospital,Capital Medical University from January 2008 to December 2016 were selected.A single center and retrospective study method was used to evaluate the cognitive function,social function of preoperative and postoperative and postoperative seizure classification.The follow－up time points included preopera-tive,posto-perative in 6 months,1 year after operation and postoperative annual review.Results A total of 43 patients were followed up,including 19 females and 24 males,with an average age of (9.37 ± 4.18)years old.The time of fol-low－up was (43.90 ± 33.04)months.According to Engel classification:GradeⅠ3 cases (7.0%),gradeⅡ3 ca-ses (7. 0%),grade Ⅲ14 cases (32.6%),grade Ⅳ21 cases (48.8%).According to McHugh classification:GradeⅠ8 cases (18.6%),grade Ⅱ12 cases (28%),gradeⅢ11 cases (25.5%),gradeⅣ6 cases (14.0%),gradeⅤ4 cases (9.3%).Speech improvement of postoperative:significant improvement in 3 cases (7.0%),slightly improved in 17 cases (39.6%);interpersonal communication improvement of postoperative:significantly increased 7 cases (16. 4%), slightly improved 16 cases(37.2%);learning/working ability improvement of postoperative:significantly improved 6 cases (14. 0%),slightly increased 14 cases(32. 6%).The postoperative VIQ (6.21 ±5.02)scores,PIQ (7.28 ±6.10)scores,FIQ (2.93 ±3.74)scores and MQ were (4.81 ± 2.98)scores higher than preoperative.Conclusions VNS can effectively im-prove the seizures of post－encephalitic epilepsy as well as the children's quality of life,cognition and social function.
ABSTRACT
Objective To investigate the prognosis and its influencing factors of post-encephalitic epilepsy ( PEE) .Methods Fifty viral encephalitis patients with PEE were followed up, which prognosis was observed by whether their no seizures for at least 1 year or not.The clinical data of patients was collected, and the relate risk factors on the poor prognosis of PEE were analyzed.Results The disturbance of consciousness and the seizure presence during acute encephalitis, more than ten seizures in poor prognosis group were much higner than the good one (all P0.05 ) .Multiple logistic regression analysis demonstrated that disturbance of consciousness during acute encephalitis、seizures presence in acute encephalitis were independent risk factors of poor outcome in PEE ( OR=7.269,95%CI:1.22 -43.35,P=0.029;OR =22.893,95%CI:4.02 -130.43,P=0.000).Conclusion Disturbance of consciousness during acute encephalitis, seizure presence in acute encephalitis both are the single risk factors of poor prognosis in PEE.
ABSTRACT
BACKGROUND: To evaluate the prognostic factors of seizure recurrence in newly diagnosed epilepsy at 1 year follow up. METHODS: From the IUED (Inje University Epilepsy Database) we retrieved the epilepsy patients who had never before taken any antiepileptics (AED) and were followed up for 1 year. We retrospectively reviewed the medical records with special attention to : a) age of onset, b) history of antecedents, c) seizure frequency before starting AED, d) abnormal neurological examination, e) MRI findings, f) EEG findings, g) epileptic syndrome classification. We defined seizure recurrence as any seizure occurring during the 1 year evaluation follow up except during the AED titra-tion period, having only an aura and being in poor compliance. We analyzed the prognostic factors that could reliably predict the seizure recurrence at 1 year follow up. RESULTS: We found 104 patients (64 male, 40 female) who met the inclusion criteria. The mean age of onset was 23.7 years. Of 104 patients 19 had generalized epilepsy, 82 had partial epilepsy and 3 had unclassified epilepsy. Thirteen percent (13/104) developed seizure recurrence at the 1 year follow up. Significant univariate associations were noted between seizure recurrence and these factors: presence of antecedents [odds ratio (OR) 4.8; 95% confidence interval (CI) 1.2-18.5 ], post-encephalitic epilepsy (OR 7.7; 95% CI 2.1 ~ 28), and abnormal neurological examination(OR 14.6; 95% CI 3.9-55). With multivariate logistic regression, the independent predictor of seizure recurrence was the abnormal neurological examination (OR 9.7; 95% CI 2.4 ~ 39.4). CONCLUSIONS: The chance of developing a seizure recurrence at the 1 year follow up was 13 percent and the prognostic factors were the presence of antecedents, post-encephalitic epilepsy and an abnormal neurological examination.
