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.
Objective The purpose of this study was to explore the expressions of EPO-R, JAK2 and STAT-5 in the human brain with refractory epilepsy and the role in neural apotosis. Methods Collecting the brain tissue of 24 patients with intractable epilepsy (as experimental group) who were hospitalized and underwent surgery in the Epilepsy Center of the First Hospital Jilin University between March 2010 to July 2011 and 6 cases of accidental or unnatural death immediately following autopsy (as control group) as required by law during the same term. Immunohistochemical was performed to observe the expression of EPO-R, JAK2 and STAT-5 in brain tissue and statistical analysis was performed. Results ① EPO-R, JAK2 and STAT-5 were expressed in both experimental and control groups. In experimental group, the positive-cell number were 41.05±2.40, 50.21±2.50 and 60.18±2.84 under light microscope (400×). While in control group, the positive-cell number were 23.00±0.49, 27.00±0.88 and 25.93±0.33. There were significant differences between the 2 groups (P<0.001). ② There were the pathologic and ultrastructural changes in the human brain with refractory epilepsy. Under the optical microscope, we can observe that the distribution of neurons was uneven and immature neurons were visible. We can see that the nuclei were vacuolar, less cytoplasm, dark staining, hyalomitome acidophilic body, and the neurons became triangular due to degeneration. The proliferation and hyperemia appeared in small vascular and glial cells. Under the transmission electron microscope we observed degeneration and necrosis of the nerve cells, nuclear karyopyknosis, nucleolis dyssymmetry and karyolemma breakage and even dissolution. The mitochondria and astrocytes were swelling. We also saw that part of the mitochondrial cristae was abnormal. Conclusion ① We found neuronal apotosis in the human brain with refractory epilepsy. ② The expression of EPO-R, JAK2 and STAT-5 in intractable epilepsy was significantly increased in neurons and glial cells compared with the control group. The high expression of EPO-R, JAK2 and STAT-5 is unrelated with course and frequency of epileptic seizures. ③ The pathway of EPO-R/JAK2/STAT-5 may be involved in the pathophysiological processes of neural protective effect of endogenous EPO against brain injury induced by epileptic seizures.
ObjectiveTo investigate the clinical effect of Electro-Cortico-Graphy (ECOG) monitoring on refractory epilepsy caused by double pathology. MethodsA retrospective analysis was performed on 10 patients with refractory epilepsy who underwent surgical treatment in Hunan Brain Hospital from January 2020 to December 2021. The diagnosis of postoperative disease was dual pathology of medial temporal lobe sclerosis (MTS) and focal cortical dysplasia (FCD), and the effect of oral drugs was poor. All patients underwent full preoperative evaluation to determine the scope of excision of epileptogenic lesions. Cortical electrodes were used to monitor the location and scope of epileptic discharge during the operation. Epileptogenic lesions were excised, cortical heat cautery was performed, and then cortical EEG monitoring was performed to adjust the excision strategy. The patients were followed up for 24 to 48 months, and the prognosis was assessed according to the Engel scale. ResultsAmong the 10 patients, 1 patient had acute subdural hemorrhage after surgery, 1 patient had speech and naming disorders, but all of them were recovered at discharge. The other patients had no neurological defects such as intracranial infection, hemiplegia, aphasia, etc. Engel grade I was observed in 9 cases (90%) and Engel grade III was observed in 1 case (10%). ConclusionCortical electrode monitoring is safe and effective for refractory epilepsy caused by double pathological signs.
ObjectiveTo investigate the effect of medical counseling games on ketogenic diet therapy for drug-resistant epilepsy children. MethodsA total of 98 children with drug-resistant epilepsy admitted to the neurology ward of Shenzhen Children's Hospital from January 2023 to June 2024 who were treated with ketogenic diet for the first time were selected as the study objects by random number table method, and were divided into observation group (n=49) and control group (n=49). The control group received the traditional multidisciplinary team health education mode, while the observation group received the ketogenic diet treatment based on the multidisciplinary team health education mode and participated in the customized medical counseling games intervention. The time of children reaching ketosis, the knowledge level of ketogenic diet caregivers and the retention rate of children on ketogenic diet were compared between the two groups. ResultsThe time of ketosis in observation group was earlier than that in control group (P<0.05). The knowledge level of the main caregivers of ketogenic diet and the retention rate of children with ketogenic diet at 3 months and 6 months in observation group were higher than those in control group (P<0.05). ConclusionThe use of medical counseling games in the ketogenic diet for medically refractory epilepsy is an effective therapeutic strategy that facilitates the early attainment of ketosis in children with medically refractory epilepsy, improves the knowledge of caregivers on the ketogenic diet, improves retention of children on the ketogenic diet, and serves to optimize the effectiveness of clinical outcomes, which may contribute to the quality of life of children with medically refractory epilepsy.
Background To summarize the genetic characteristics of GATOR1 complex gene mutations and the surgical prognosis of patients with refractory epilepsy. Methods A retrospective analysis was conducted on 16 patients with GATOR1 complex gene mutations who presented with mainly refractory epilepsy and underwent surgical treatment at the Epilepsy Center of Tsinghua University Yuquan Hospital from May 2019 to August 2024. The follow-up period ranged from 0.5 to 4.0 years. The genetic characteristics, clinical data, treatment, and prognosis of the patients were analyzed. Results Among the 16 patients, 9 were male and 7 were female, with an onset age ranging from 0.6 to 9.4 years, and seizure frequency ranging from once a day to dozens of times a day. Twelve patients (75.0%) had no seizures after surgery, and three of them had completely stopped taking medication. EEG were focal or multifocal, and all clinical seizures were monitored. Two patients had negative MRI. Among the 16 patients, there were 8 with DEPDC5 gene mutations, 5 with NPRL3 gene mutations, and 3 with NPRL2 gene mutations. Conclusions Patients with refractory epilepsy related to GATOR1 complex gene mutations are good surgical candidates, with a high rate of no seizures after surgery. For confirmed patients, surgical treatment should be considered.
