    背景:抗IgLON5脑炎是一种罕见的神经系统疾病,主要见于成人。很少报道与抗IgLON5疾病相关的癫痫发作。
    方法:使用免疫荧光双重染色的基于细胞的测定法(CBA)检测血清和脑脊液(CSF)中与自身免疫性脑炎相关的神经抗体。血清中的抗体通过大鼠脑和肾组织的基于组织的测定(TBA)进一步证实。
    结果:我们报道了一例出现癫痫发作的儿科病例,认知障碍,和睡眠障碍。自身抗体筛选显示血清中的抗IgLON5抗体IgG(1:100+)和抗NMDAR抗体IgG(1:10+)。她被诊断为抗IgLON5脑炎。通过静脉注射免疫球蛋白和大剂量静脉注射甲泼尼龙治疗,她的病情迅速改善。
    结论:我们描述了第二例抗IgLON5脑炎的儿科病例,他也是第一个出现癫痫发作的人。抗IgLON5脑炎可能有轻度表现。对于与认知障碍和睡眠障碍相关的新发作癫痫患者,抗IgLON5抗体应尽早测试,即使在孩子们。
    BACKGROUND: Anti-IgLON5 encephalitis was a rare neurological and heterogeneous disorder, which was mainly found in adults. Epileptic seizures related to anti-IgLON5 disease were rarely reported.
    METHODS: Neural antibodies associated with autoimmune encephalitis in serum and cerebrospinal fluid (CSF) were tested using cell-based assays (CBA) with immunofluorescence double staining. The antibodies in serum were further confirmed by tissue-based assay (TBA) with rat brain and kidney tissue.
    RESULTS: We reported a pediatric case presented with epileptic seizures, cognitive impairments, and sleep disorders. Autoantibody screening showed anti-IgLON5 antibody IgG (1:100+) and anti-NMDAR antibody IgG (1:10+) in the serum. She was diagnosed as anti-IgLON5 encephalitis. Her conditions improved rapidly by treated with intravenous immunoglobulin and high dose intravenous methylprednisolone.
    CONCLUSIONS: We described the second pediatric case with anti-IgLON5 encephalitis, who was also the first presented with epileptic seizures as the initial presentation. Anti-IgLON5 encephalitis might have mild manifestations. For patients with new onset seizures associated with cognitive impairments and sleep disturbances, anti-IgLON5 antibody should be tested as early, even in children.

    背景:全球超过60%的癫痫患者是儿童,他们的早期诊断和治疗对他们的发展至关重要,可以大大减少疾病对家庭和社会的负担。已经提出了许多用于从EEG自动检测癫痫的算法。然而,在临床实践中,无法始终保证脑电图检查期间癫痫发作的发生。专门使用癫痫发作EEG进行检测风险的模型人为增强了性能指标。因此,迫切需要一种普遍适用的模型,可以在各种复杂的现实场景中执行自动癫痫检测。
    方法:为了解决这个问题,我们设计了一种新技术,采用具有自我注意力的时间卷积神经网络(TCN-SA)。我们的模型包括两个主要成分:从EEG信号中提取时变特征的TCN,其次是一个自我注意(SA)层,赋予这些特征的重要性。通过关注关键特征,我们的模型提高了癫痫检测的分类准确性.
    结果:在我们收集的小儿癫痫数据集和波恩数据集上验证了我们模型的有效性,在我们的数据集上达到95.50%的准确率,和97.37%(Av.E),和93.50%(B对E),分别。与其他深度学习架构(时间卷积神经网络,自我关注网络,和标准化的卷积神经网络)使用相同的数据集,我们的TCN-SA模型在癫痫自动检测方面表现优异.
    结论:TCN-SA方法的有效性证明了其作为自动检测癫痫的有价值工具的潜力,在多样化和复杂的现实世界的临床设置提供显著的好处。
    BACKGROUND: Over 60% of epilepsy patients globally are children, whose early diagnosis and treatment are critical for their development and can substantially reduce the disease\'s burden on both families and society. Numerous algorithms for automated epilepsy detection from EEGs have been proposed. Yet, the occurrence of epileptic seizures during an EEG exam cannot always be guaranteed in clinical practice. Models that exclusively use seizure EEGs for detection risk artificially enhanced performance metrics. Therefore, there is a pressing need for a universally applicable model that can perform automatic epilepsy detection in a variety of complex real-world scenarios.
    METHODS: To address this problem, we have devised a novel technique employing a temporal convolutional neural network with self-attention (TCN-SA). Our model comprises two primary components: a TCN for extracting time-variant features from EEG signals, followed by a self-attention (SA) layer that assigns importance to these features. By focusing on key features, our model achieves heightened classification accuracy for epilepsy detection.
    RESULTS: The efficacy of our model was validated on a pediatric epilepsy dataset we collected and on the Bonn dataset, attaining accuracies of 95.50% on our dataset, and 97.37% (A v. E), and 93.50% (B vs E), respectively. When compared with other deep learning architectures (temporal convolutional neural network, self-attention network, and standardized convolutional neural network) using the same datasets, our TCN-SA model demonstrated superior performance in the automated detection of epilepsy.
    CONCLUSIONS: The proven effectiveness of the TCN-SA approach substantiates its potential as a valuable tool for the automated detection of epilepsy, offering significant benefits in diverse and complex real-world clinical settings.

    目的:已发现卵圆孔未闭(PFO)的闭合手术可有效控制隐源性中风和偏头痛,但不确定PFO封堵是否也能缓解癫痫发作。本研究旨在观察PFO封堵术对癫痫发作的治疗效果。
    方法:自7月11日起,2017年,在华西医院神经内科,四川大学,成都,我们一直定期对接受PFO封堵术的癫痫患者进行监测.患者的临床信息,比如频率,持续时间,以及癫痫发作的严重程度,详细记录手术前后以及术后安全事件.
    结果:在31例确诊PFO的癫痫患者中(27例为耐药性癫痫,87.10%),手术平均年龄为23.74岁,女性12例(38.71%)。经过一年的随访,26例患者(83.87%)实现了癫痫发作频率的缓解,其中22人(70.97%)的缓解率超过50%。此外,与手术前相比,22例(70.97%)报告平均癫痫发作持续时间减少,20例(64.52%)报告癫痫发作严重程度降低。在发作频率指标中,平均持续时间和严重程度,术前和术后比较存在显著差异,所有检验p值均<0.05.此外,除一名短暂报告胸痛的患者外,未报告严重的安全事件,所有患者均表示有效的PFO闭合。
    结论:PFO闭合首次被证明导致频率显着降低,持续时间,以及癫痫发作的严重程度。耐药性癫痫和大分流PFO的患者是进行PFO闭合的理想人选。
    结论:由于发现PFO封堵术对隐源性中风和偏头痛有良好的治疗效果,它已成为治疗神经系统疾病的可靠补充疗法,而伴有PFO的耐药癫痫有望成为下一个PFO封堵术可显著改善的目标疾病。
    OBJECTIVE: Closure surgery of patent foramen ovale (PFO) has been found to effectively control cryptogenic stroke and migraine, but it is uncertain whether PFO closure could also alleviate epileptic seizures. This study aims to observe the therapeutic effect of PFO closure on epileptic seizures.
    METHODS: Since July 11th, 2017, in the neurology department of West China Hospital, Sichuan University, Chengdu, we have been regularly monitoring patients with epilepsy who have undergone PFO closure. The patient\'s clinical information, such as frequency, duration, and severity of seizures, before and after surgery was recorded in detail as well as postoperative safety events.
    RESULTS: Of the 31 epilepsy patients who confirmed PFO observed (27 cases were drug-resistant epilepsy, 87.10%), average age of surgery was 23.74 years, and 12 cases were female (38.71%). After one-year follow-up, 26 patients (83.87%) achieved remission of seizure frequency, and 22 of whom (70.97%) experienced a remission of more than 50%. Additionally, compared to before surgery, 22 cases (70.97%) reported a decrease in the average seizure duration, and 20 cases (64.52%) reported a reduction in seizure severity. In the seizure indicators of frequency, average duration and severity, significant differences were identified between preoperative and postoperative comparisons with all test p values were <0.05. Furthermore, no serious safety events were reported except for one patient who briefly reported chest pain, and all patients expressed effective PFO closure.
    CONCLUSIONS: The PFO closure has been shown for the first time to result in a significant reduction in the frequency, duration, and severity of seizures. Patients with drug-resistant epilepsy and PFO with a large shunt are ideal candidates for undergoing PFO closure.
    CONCLUSIONS: Since PFO closure was found to have a good therapeutic effect on cryptogenic stroke and migraine, it has become a credible complementary therapy for the treatment of neurological diseases, and drug-resistant epilepsy with PFO is expected to become the next target disease that PFO closure could significantly improve.

    高甘油三酯血症引起的急性胰腺炎很少发生在妊娠糖尿病的妊娠中期。对于这些患者来说,关于伴随高血糖的现有知识不足.我们报告了一例妊娠糖尿病和高甘油三酯血症诱发的急性胰腺炎围产期高血糖后胎盘早剥和癫痫发作的病例。胎盘早剥和癫痫发作的发生可能与伴随的高血糖有关。在接受胰岛素治疗后,癫痫发作终止。即使患者已度过高甘油三酯血症诱发的急性胰腺炎急性期,我们也应更加重视围产期高血糖的不良反应,继续给予适当的胰岛素治疗。
    Hypertriglyceridemia-induced acute pancreatitis seldom occurs in the second trimester of pregnancy with gestational diabetes mellitus. For these patients, the existing knowledge on concomitant hyperglycemia is not sufficient. We report a case of abruptio placentae and epileptic seizure following perinatal hyperglycaemia in woman with gestational diabetes mellitus and hypertriglyceridemia-induced acute pancreatitis. The occurrence of abruptio placentae and epileptic seizure may be associated with concomitant hyperglycemia, and the epileptic seizure was terminated after she underwent treatment with insulin. We should pay more attention to the adverse effects of perinatal hyperglycemia and continue to give appropriate insulin treatment even if patients have passed the acute phase of hypertriglyceridemia-induced acute pancreatitis.

    目的:验证与神经元表面抗体(Ab)介导的自身免疫性脑炎(AE)相关的新发癫痫发作或病因不明的癫痫患者的不同预测评分量表。
    方法:我们回顾性回顾了2018年10月至2022年12月174例连续患者的图表,对其血清和脑脊液样本进行了神经元表面Abs检测。癫痫和脑病(APE2)中的抗体患病率,导致局灶性癫痫体征和症状(ACES)的抗体,癫痫或癫痫发作(ONES)清单中神经抗体测试的“明显”适应症,和组合用于验证神经元表面Ab介导的AE的预测模型。
    结果:共纳入139例新发癫痫发作或病因不明的癫痫患者。在37例患者中检测到Abs(26.6%)。APE2/ONES反射评分敏感性最高(89.2%),特异性最低(41.7%)。ACES评分的敏感性最低(67.5%),特异性最高(64.7%)。在不同类型的AE中观察到性能的变化。100%的抗γ-氨基丁酸B-B受体脑炎的患者被预测的ONES,APE2/ONES反射,和ACES/ONES反射得分。APE2/ONES和ACES/ONES反射评分可预测抗N-甲基-D-天冬氨酸受体脑炎患者中只有75%。
    结论:我们的研究首次在中国新发癫痫发作或与神经元表面Ab介导的AE相关的病因不明的癫痫患者队列中验证了各种预测评分量表。基于临床怀疑,应使用一个以上的评分表来预测这些患者的AE几率.
    To validate the different predictive scoring scales in the Chinese population with new-onset epileptic seizures or epilepsy of unknown etiology related to neuronal surface antibody (Ab)-mediated autoimmune encephalitis (AE).
    We retrospectively reviewed the charts of 174 consecutive patients from October 2018 to December 2022, whose serum and cerebrospinal fluid samples were tested for neuronal surface Abs. The antibody prevalence in epilepsy and encephalopathy (APE2), antibodies contributing to focal epilepsy signs and symptoms (ACES), \"obvious\" indications for neural antibody testing in epilepsy or seizures (ONES) checklist, and the combinations were used to validate the predictive models of neuronal surface Ab-mediated AE.
    A total of 139 patients with new-onset epileptic seizures or epilepsy of unknown etiology were enrolled. Abs were detected in 37 patients (26.6%). The APE2/ONES reflex score had the highest sensitivity (89.2%) and lowest specificity (41.7%). The ACES score had the lowest sensitivity (67.5%) and highest specificity (64.7%). Variations in the performance were observed in the different types of AE. 100% of patients with anti-γ-aminobutyric acid B-B receptor encephalitis were predicted by ONES, APE2/ONES reflex, and ACES/ONES reflex scores. Only 75% of patients with anti-N-methyl-D-aspartate receptor encephalitis were predicted by the APE2/ONES and ACES/ONES reflex scores.
    Our study was the first to validate various predictive scoring scales in the Chinese cohort of patients with new-onset epileptic seizures or epilepsy of unknown etiology related to neuronal surface Ab-mediated AE. Based upon clinical suspicion, more than one scoring scale should be performed to predict the chance of AE in those patients.

    我们介绍了一名年轻男性患者的情况,该患者经历了短暂的意识丧失,并在头部向后倾斜时表现出癫痫发作。经颅多普勒超声(TCD)和颈动脉超声(CAU)检查正常,患者颈部处于中立位置。然而,CAU显示在颈部旋转或向后运动期间椎动脉(VA)短暂闭塞。脑电图(EEG)监测是通过多次颈部旋转引起的测试进行的。病人出现头晕,这与第一次癫痫发作的前驱症状相同,脑电图显示额叶到额叶中线区域有大量的脊髓慢波和尖锐的慢波,偶尔会有泛化趋势。CT血管造影显示,当患者的头部向右旋转时,在VA的局部区域中缺乏造影剂填充。因此,患者被诊断为BowHunter综合征(BHS),并采取颈部固定保守治疗。随访3、6个月无复发。因此,该病例提醒神经科医生怀疑BHS在颈部旋转过程中观察到癫痫发作表现,CAU可能是BHS推荐的动态筛查方法。本报告伴随着对现有文献中的现象和诊断的讨论。
    We present the case of a young male patient experiencing a transient loss of consciousness and manifesting a seizure when he tilted his head backward. Transcranial Doppler ultrasound (TCD) and carotid artery ultrasound (CAU) examination were normal when the patient\'s neck was in the neutral position. However, the CAU revealed vertebral artery (VA) transient occlusion during neck rotation or backward movement. Electroencephalogram (EEG) monitoring was performed with multiple neck rotation-induced tests. The patient developed dizziness, which was the same as the prodromal symptoms of the first seizure, and the EEG showed a large number of spinal slow waves and sharp slow waves in the frontal-to-frontal midline area, with an occasional generalization trend. CT angiography revealed occipitalization of the atlas and the lack of contrast agent filling in the local area of the VA when the patient\'s head was turned contralaterally. Thus, the patient was diagnosed with Bow Hunter\'s syndrome (BHS) and treated conservatively with neck immobilization. No recurrence occurred at 3 and 6 months of follow-up. Therefore, this case alerts neurologists to suspect BHS on observing seizure manifestations during neck rotation, and CAU may be a recommended dynamic screening method for BHS. This report is accompanied by a discussion of the phenomenon and diagnosis in the context of the existing literature.

    癫痫是一种常见的神经系统疾病。癫痫的影响不仅限于癫痫发作。它们包括可能损害和降低生活质量的广泛问题。即使使用药物,30%的癫痫患者仍有反复发作。癫痫发作是由显著的神经元电活动引起的,影响大脑活动。EEG将这些变化显示为高振幅的尖峰波和缓慢波。由专业神经科医生手动识别脑电图(EEG)上的癫痫发作是一个耗时且费力的过程,因此,有效的自动化方法对于识别癫痫发作是必要的。一种提高癫痫发作诊断速度和准确性的技术是利用基于深度神经网络的计算机辅助诊断系统。或DNN。这项研究引入了递归神经网络(RNN)和双向长期短期记忆(BiLSTM)的融合,用于通过EEG信号处理进行自动癫痫发作识别,以应对上述信息挑战。脑电图(EEG)原始数据在经过预处理后首先被标准化。RNN模型被馈送归一化的EEG序列数据并且被训练以从数据中准确地提取特征。之后,特征被传递到BiLSTM层进行处理,以便可以检索进一步的时间信息。此外,使用可自由获取的UCI癫痫发作数据集,在实验环境中测试了所提出的RNN-BiLSTM模型.建议模型的实验结果达到了98.90%的平均值,98.50%,98.20%,98.60%,分别,为了准确,灵敏度,精度,和特异性。为了进一步验证新模型的有效性,它与其他型号相比,例如RNN-LSTM和RNN-GRU学习模型,并显示相同的指标提高了1.8%,1.69%,1.95%,和2.2%使用5倍。此外,将所提出的方法与最先进的方法进行了比较,并证明是对此类技术的更准确分类。
    Epilepsy is a common neurological condition. The effects of epilepsy are not restricted to seizures alone. They comprise a wide spectrum of problems that might impair and reduce quality of life. Even with medication, 30% of epilepsy patients still have recurring seizures. An epileptic seizure is caused by significant neuronal electrical activity, which affects brain activity. EEG shows these changes as high-amplitude spiky and sluggish waves. Recognizing seizures on an electroencephalogram (EEG) manually by a professional neurologist is a time-consuming and labor-intensive process, hence an efficient automated approach is necessary for the identification of epileptic seizure. One technique to increase the speed and accuracy with which a diagnosis of epileptic seizures could be made is by utilizing computer-aided diagnosis systems that are built on deep neural networks, or DNN. This study introduces a fusion of recurrent neural networks (RNNs) and bi-directional long short-term memories (BiLSTMs) for automatic epileptic seizure identification via EEG signal processing in order to tackle the aforementioned informational challenges. An electroencephalogram\'s (EEG) raw data were first normalized after undergoing pre-processing. A RNN model was fed the normalized EEG sequence data and trained to accurately extract features from the data. Afterwards, the features were passed to the BiLSTM layers for processing so that further temporal information could be retrieved. In addition, the proposed RNN-BiLSTM model was tested in an experimental setting using the freely accessible UCI epileptic seizure dataset. Experimental findings of the suggested model have achieved avg values of 98.90%, 98.50%, 98. 20%, and 98.60%, respectively, for accuracy, sensitivity, precision, and specificity. To further verify the new model\'s efficacy, it is compared to other models, such as the RNN-LSTM and the RNN-GRU learning models, and is shown to have improved the same metrics by 1.8%, 1.69%, 1.95%, and 2.2% on using 5-fold. Additionally, the proposed method was compared to state-of-the-art approaches and proved to be a more accurate categorization of such techniques.

    γ-氨基丁酸A型受体(GABAARs)突触聚集的破坏和质膜中GABAARs数量的减少被认为有助于改变兴奋性和抑制性神经传递之间的平衡,促进癫痫的诱导和传播。多次跨膜蛋白唇腭裂跨膜蛋白1(Clptm1)控制GABAAR的正向运输,从而衰减抑制性突触的微型抑制性突触后电流(mIPSC)。在这项研究中,使用戊四氮(PTZ)诱导的癫痫大鼠模型,我们发现Clptm1通过调节GABAAR介导的抑制性突触传递来调节癫痫发作。首先,我们发现在PTZ诱导的癫痫大鼠中Clptm1表达升高。随后,我们发现Clptm1表达的下调可以保护PTZ诱导的癫痫发作,这归因于质膜中GABAARγ2s的数量增加和mIPSC的幅度。一起来看,我们的研究结果确定了一个新的抗惊厥靶点,为制定预防和治疗癫痫的新策略提供了理论基础.
    Disruption of gamma-amino butyric acid type A receptors (GABAA Rs) synaptic clustering and a decrease in the number of GABAA Rs in the plasma membrane are thought to contribute to alteration of the balance between excitatory and inhibitory neurotransmission, which promotes seizure induction and propagation. The multipass transmembrane protein cleft lip and palate transmembrane protein 1 (Clptm1) controls the forward trafficking of GABAA R, thus decaying miniature inhibitory postsynaptic current (mIPSC) of inhibitory synapses. In this study, using a pentylenetetrazol (PTZ)-induced epilepsy rat model, we found that Clptm1 regulates epileptic seizures by modulating GABAA R-mediated inhibitory synaptic transmission. First, we showed that Clptm1 expression was elevated in the PTZ-induced epileptic rats. Subsequently, we found that downregulation of Clptm1 expression protected against PTZ-induced seizures, which was attributed to an increase in the number of GABAA Rγ2s in the plasma membrane and the amplitude of mIPSC. Taken together, our findings identify a new anti-seizure target that provides a theoretical basis for the development of novel strategies for the prevention and treatment of epilepsy.

    抗IgLON5是一种罕见的神经系统疾病,可伴有癫痫发作。然而,癫痫发作没有被定性和漏报。我们旨在研究抗IgLON5病患者癫痫发作的临床特征和人口统计学。
    我们报道了一例出现癫痫发作的抗IgLON5疾病,并对抗IgLON5疾病患者的癫痫发作进行了全面的文献综述。我们搜查了Medline,Pubmed,和WebofScience数据库使用以下搜索算法:“IgLON5”或“抗IgLON5”或“IgLON5抗体”仅限于英文出版物。
    我们从66篇出版物中确定了183例病例。除了我们的案子,9例(4.9%)抗IgLON5病患者报告癫痫发作,无论是焦点还是广义。其中,癫痫发作是6例(3.2%)神经内科咨询的主要原因之一。癫痫发作的患者对两性的影响相似,通常在中年发展。除了癫痫发作,大多数患者有睡眠障碍和认知障碍.通过免疫疗法和抗癫痫药物治疗,癫痫发作的频率降低。
    抗-IgLON5疾病可伴有癫痫发作,我们的研究扩展了抗IgLON5疾病的临床范围。
    Anti-IgLON5 is a rare neurologic disease that can present with epileptic seizures. However, epileptic seizures have not been characterized and are underreported. We aimed to investigate the clinical characteristics and demographics of epileptic seizures in patients with anti-IgLON5 disease.
    We reported a case of anti-IgLON5 disease presenting with epileptic seizures and presented a comprehensive literature review on epileptic seizures in patients with the anti-IgLON5 disease. We searched the Medline, Pubmed, and Web of Science databases using the following search algorithm: \"IgLON5\" or \"anti-IgLON5\" or \"IgLON5 antibody\" limited to publications in English.
    We identified 183 cases from 66 publications. In addition to our case, nine (4.9%) patients with anti-IgLON5 disease had reported epileptic seizures, either focal or generalized. Of those, epileptic seizures were one of the main reasons for neurology consultation in six (3.2%). Patients with epileptic seizures affected both sexes similarly and usually developed in middle age. In addition to epileptic seizures, a majority of patients had sleep disorders and cognitive impairment. The frequency of epileptic seizures was reduced with the treatment of immunotherapy and antiseizure medication.
    Anti-IgLON5 disease can present with epileptic seizures, and our study expands the clinical spectrum of the anti-IgLON5 disease.
