ObjectiveTo explore the clinical features and surgical treatment effects of the temporal lobe epilepsy with hippocampal sclerosis.MethodsForty two patients diagnosed as temporal lobe epilepsy with hippocampal sclerosis and underwent protemporal lobectomy in Wuhan Brain Hospital from Jan. 2012 to Dec. 2018 were collected, which included 30 males and 12 females, with the age between 9 to 60 years. Their disease duration ranged from 3 to 10 years. The clinical manifestations showed complex partial seizure in 18 cases, partial-secondary –generalized seizure in 4 cases, and generalized tonic-clonic seizure in 20 cases. Based on their results of clinical manifestations, combined with MRI and VEEG results, all the patients underwent anterior temporal lobectomy (including the most parts of the hippocampus and amydala).ResultsThe postoperative pathology confirmed the diagnosis of hippocampal sclerosis. The follow-up of more than 1 year showed seizure-free in 38 cases, and significant improvement in 4 cases.ConclusionsTo the patients of temporal lobe epilepsy with hippocampal sclerosis, anterior temporal lobectomy should be performed (including the most parts of the hippocampus and amydala) if the VEEG monitoring results show that there are epileptic discharges in the ipsilateral temporal lobe. And the postoperative curative result is satisfactory.
ObjectiveTo investigate the status and prognosis effect of surgical operation for Temporal lobe epilepsy.MethodsRetrospective analyses were performed on 24 patients with intractable temporal lobe epilepsy who were treated by surgery in Zibo Changguo Hospital and had complete clinical and follow-up data, during the period from April 2011 to June 2014. Among them, 14 were male and 10 were female, 16 to 44 years old, the average age was (24.40±6.26) years old, and the average course of disease was (12.50±8.42) years old. The clinical characteristics and prognosis of the patients were analyzed.ResultsAll 24 patients had hippocampal sclerosis and underwent "anterior temporal lobe and medial temporal structural resection". Patients were followed up for 5~7 years, the postoperative epileptic seizure of the patient reached grade Engel Ⅰ in 20 cases (83.3%), grade Engel Ⅱ in 2 cases (8.3%) and grade Engel Ⅳ in 2 cases (8.3%).ConclusionHippocampal sclerosis and cortical dysplasia were common in 24 patients, and the operation controlling intractable epilepsy was better. In order to improve the prognosis of patients, surgical treatment should be carried out as soon as possible.
ObjectiveTo determine the outcome of antiepileptic drugs (AEDs) withdrawal in patients who had been seizure-free for more than two years. MethodsPatients with epilepsy who had been seizure-free for at least two years and decided to stop AEDs therapy gradually were checked on every two months for seizure relapse. The inclusion criteria were:①diagnosis of epilepsy, defined as at least two unprovoked seizures at least 24 hours apart; ②patients remained seizure-free for at least 24 consecutive months during AEDs therapy; ③patients expressed a desire to discontinue AEDs therapy gradually and agreed to return for regular follow-ups; and④electroencephalogram (EEG) showed no epileptic discharge. The time to a seizure relapse and predictive factors were analyzed by survival methods, including sex; age at seizure onset; number of episodes; seizure-free period before AEDs withdrawal; duration of follow-up after AEDs withdrawal; AEDs tapering off period (taper period); results from brain MRI; EEG before seizure-free; EEG before drug withdrawal; seizure type (classified as generalized, partial, or multiple types based on history); the number of AEDs administered for long-term seizure control. A log-rank test was used for univariate analysis, and a Cox proportional hazard model was used for multivariate analysis. ResultsSixty-eight patients (39 male, 29 female) were admithed. The relapsed rate was 23.5%. Univariate analysis and multivariate Cox regression analysis indicated that multiple AEDs, hippocampal sclerosis and withdrawal time were significantly correlated with seizure recurrence and those were significant independent predictive factors, with hazard ratio were 0.861, 2.223 and 2.137 respectively. ConclusionsThe relapsed rate in our study was similar to other studies. Distinguishing variables, such as multiple AEDs, hippocampal sclerosis and withdrawal time, need to be considered when decide to withdraw. Therefore, our recommendation is that after two years of being seizure-free, patients could consider withdrawal unless they are hippocampal sclerosis patients.
ObjectiveTo study the cytokine changes in the cerebrospinal fluid (CSF) of mesial temporal lobe epilepsy (MTLE) patients, and the mechanism of the development of hippocampal sclerosis. MethodsFifty MTLE patients who sought treatment from January 2013 to March 2014 were included in the study. Clinical features were investigated. All CSF samples of the 59 patients along with 19 samples of the control group were tested for 12 common cytokines using a chemokine magnetic bead panel. Data were statistically analyzed. ResultsClinical features showed no significant difference between hippocampal sclerosis and non-hippocampal sclerosis patients. Interleukin (IL)-1 receptor antagonist (RA), IL-4 and IL-9 expression decreased, and tumor necrosis factor (TNF)-α, IL-3 and IL-5 expression increased. Up-regulation of TNF-α was significantly different between hippocampal sclerosis and non-hippocampal sclerosis patients. ConclusionIL-1RA, IL-3, IL-4, IL-5 and IL-9 changes may be non-specific seizure-related cytokine regulation. TNF-α is associated with hippocampal sclerosis pathology. TNF-α is a possible pathological element in hippocampal sclerosis development.
