  • 癫痫的侵袭性术前评估

    癫痫切除手术前精确定位致痫灶至关重要,目前,对于综合无创性评估仍无法定位致痫灶或区分功能区的患者,国际上常采用硬膜下电极脑电图监测(Subduralel ectrodes EEG, SDEG)和立体定向脑电图(SEEG)两种侵袭性颅内脑电图(intracranial electroencephalography, iEEG)评估方法进一步定位致痫灶及区分功能区。SDEG 优势在于其相邻皮质覆盖连续性较好、皮层与电极的解剖关系清楚以及功能区定位相对容易;缺点主要在于对深部脑组织覆盖监测较差、癫痫起源的三维结构难以体现、双侧或相隔较远的多个区域植入困难以及创伤较大、并发症比例较高。SEEG 的优点在于定位深部皮质相对容易、癫痫起源的三维结构清楚、微创性高、适合双侧或相隔较远的多个区域植入;缺点在于相邻皮质覆盖连续性较差、功能区定位相对困难、植入过程中可损伤颅内血管导致颅内出血。近年来,iEEG 监测快速发展,但仍需进一步探索,如通过技术的不断改进及创新实现精确植入电极及降低植入并发症,通过设计临床前瞻性研究进一步研究 SDEG 和 SEEG 在定位致痫灶、切除范围及术后疗效的差异等。目前,SDEG 和 SEEG 在术前定位致痫灶方面各有优缺点,临床上应根据患者的具体情况个体化选择方案。

    ObjectiveTo observe the clinical efficacy of Xiao’er kang xian capsule added to anti-seizure medications (ASMs) in the treatment of children with refractory epilepsy and its influence on serum neuron-specific enolase (NSE) and cludter of differentiation 19+ (CD19+) levels. Methods A total of 60 children with refractory epilepsy were selected from the pediatric outpatient department and ward of Guangdong Provincial People's Hospital from February 2021 to June 2023. The study subjects were divided into two groups by numerical random method,with 30 cases in each group. The children with Xiao’er kang xian capsule added to the original treatment were the treatment group and the children without Xiao’er kang xian capsule added to the original treatment were the control group. The frequency, duration, EEG characteristics, adverse reactions and changes in serum NSE and CD19+ levels of the two groups were compared after treatment. Results Self-control before and after treatment in the treatment group: the frequency and duration of seizures were significantly reduced, with statistical difference (P<0.05). EEG discharge index in awake period and sleep period were significantly decreased, with statistical difference (P<0.05). After 6 months of treatment, comparison between the two groups of children: the seizure frequency of children in the treatment group was significantly decreased compared with the control group (P=0.03). There was a statistical difference (P<0.05), and the seizure duration in the treatment group was less than that in the control group (P=0.863), the clinical effective rate of treatment group 83.33% was higher than that of control group 63.33% (P=0.08), the effective rate of EEG in treatment group 80% was higher than that of control group 60% (P=0.091), serum NSE and CD19+ in treatment group were lower than that of control group, with no statistical difference (P>0.05). After 12 months of treatment, the frequency and duration of seizures in the treatment group were significantly decreased (P<0.05). The clinical efficacy and effectiveness of treatment group were significantly higher than that of control group (P=0.038). The incidence of adverse reactions in both groups was 16.67% (P>0.05). The effective rate of EEG in treatment group was significantly higher than that in control group (P=0.053). Serum NSE and CD19+ in treatment group were significantly lower than those in control group (P<0.05). ConclusionFor children with refractory epilepsy, the addition of Xiao’er kang xian capsule on the basis of the original treatment has obvious effect low adverse reaction and high safety.

  • Clinical effect of cortical electrode monitoring on intractable epilepsy caused by double pathology

    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.

  • The clinical analysis of ketogenic diet therapy in children with rapidly progressive Dravet syndrome

    ObjiectiveTo explore the efficacy and safety of ketogenic diet therapy (KDT) in the rapidly progressive stage of childhood developmental epileptic encephalopathy Dravet syndrome (DS). Methods The clinical data of all patients who added KDT in the Children’s Hospital of Fudan University from 2011 to 2022 were retrospectively collected, and the age of <6 years was used as the criterion for the rapid progression of the disease. The clinica data, genotype and the efficacy of KDT were analyzed in DS patients who met the criteria. Results A total of 32 patients met the criteria for rapid disease progress, including 22 males and 10 females. The age at onset was (5.69±2.10) months. All patients had multiple seizure phenotypes and monthly seizures despite reasonable Antiseizure medications treatment. After 3, 6, 12, and ≥24 months, 93.8% (30/32), 87.5% (28/32), 53.1% (17/32), 34.4% (11/32) remained on the KDT, while 76.7% (23/30), 75.0% (21/28), 70.6% (12/17), 54.5% (6/11) showed >50% reduction in seizure. Status epileptius (SE) was reduced by 100% at 3 months, 71.0% at 6 months, 86.0% at 12 months. After 12 months, 14 patients experienced efficacy degradation. After 3 months, the EEG background rhythm showed improvement in 75.0% patients, interictal epileptic discharges was decreased in 54.5% patients and cognitive function was improved in 78.6% patients. At the initial stage of KDT, 62.5% (20/32) patients had transisent adverse reactions, including diarrhea, vomiting, fatigue, lethargy, hypoglycemia, and metabolic acidosis, but no mid- and long-term adverse reactions were found. ConclusionKDT is an efficective and safe treatment for DS. KDT can effectively control seizures, reduce the incidence of Status SE and shorten the duration of SE. With the prolongation of the KDT course, some patients experienced a degraded effect. KDT can improve abnormal EEG and cognitive function in DS patients. Pharmoco-resistant DS patients are suggested to receive KDT in the early stage of disease progression.

  • Efficacy and predictive factors analysis of vagus nerve stimulation in patients with refractory MRI-negative epilepsy

    ObjectiveTo investigate the efficacy of vagus nerve stimulation (VNS) in patients with refractory magnetic resonance imaging (MRI)-negative epilepsy and to evaluate potential clinical predictors. MethodsA retrospective collection of efficacy data was conducted on 24 patients with intractable MRI-negative epilepsy treated with VNS, who were followed up for more than six months, at Beijing Tiantan Hospital and Beijing Fengtai Hospital from January 2016 to September 2023. Patients were divided into two subgroups based on their response to VNS: responders (≥50% reduction in seizure frequency) and non-responders (<50% reduction in seizure frequency). The relationship between preoperative clinical data and VNS efficacy was further analyzed to identify potential predictors of VNS efficacy. ResultsA total of 24 patients were included, with an average age of (14.26±8.39) years old. Seizure frequency was reduced by more than 50% in 37.5% of patients, and 8.3% of patients achieved seizure-free after VNS treatment. Preoperative seizure frequency and interictal epileptiform discharge type were significantly associated with VNS efficacy (P<0.05). Multivariate regression analysis showed that a monthly seizure frequency of less than 100 and focal interictal epileptiform discharges were independent predictors of VNS efficacy (P<0.05). ConclusionVNS is an effective treatment for patients with refractory MRI-negative epilepsy. Lower monthly seizure frequency and focal interictal epileptiform discharges are potential predictors of VNS efficacy. These findings provide important references for clinicians in selecting and evaluating patients for VNS treatment.
