Objectives Retrospective analysis of the Tibetan convulsive status epilepticus (CSE) for the aetiology, prognosis and its influencing factors in Tibet area. Methods Through electronic patient record, making “epilepsy”, “status epilepticus ”, “epileptic seizure” as keywords, convulsive status epilepticus patients in the People’s Hospital of Tibet Autonomous Region hospitalized from January 2015 to December 2020 were retrospectively observed, gathering their clinical data and aided examinations furthermore, and the prognoses were returned by telephone, meanwhile the functional status of those patients was assessed by the modified rankin scale. and the causes differ in gender, age, out-of-hospital antiepileptic treatment, family history of epilepsy and history of epilepsy were analyzed. The prognostic factors were analyzed by logistic regression. Results A total of 2 254 hospitalized patients with epilepsy were retrieved, including 331 CSE patients aged 14~84 years, 219 males and 112 females. There were 36 lost calls, 62 CSE deaths (21.01%), and 4 adverse outcomes (non-death)(1.7%).There were statistically significant differences in etiology of CSE in different ages and history of epilepsy (P<0.05), but there were no statistically significant differences in gender, out-of-hospital antiepileptic treatment, progression of refractory status epilepticus and family history of epilepsy. Cerebrovascular disease was the main cause of CSE in people aged 45 and over (54 cases), while the main cause of CSE in people aged under 45 was unknown (104 cases).Among the patients with previous history of epilepsy, the highest proportion was unknown cause [117 cases (48.8%)]; Among patients without a history of epilepsy, cerebrovascular disease [34 cases (37.4)] was the most common cause of CSE. Multivariate logistic regression analysis of prognostic factors of CSE showed that gender, age, GCS and electrolyte disorder had statistically significant effects on the death of CSE patients (P<0.05), while altitude and their duration and other factors had no statistically significant effects on the death of CSE patients (P>0.05). ConclusionsCerebrovascular disease is the leading cause of CSE in people aged 45 and over. Male, advanced age, low GCS score at discharge, and electrolyte disorder were risk factors.
Purpose To analyze the clinical characteristicsand prognostic factors of Status epilepticus (SE) in children. Methods The clinical data of 33 children with SE treated in Jinan Central Hospital Affiliated of Shandong University from January 2014 to June 2021 were collected, and their clinical characteristics were analyzed. Then, according to Glasgow prognosis scale, the children were divided into good prognosis group (n=20) and poor prognosis group (n=13). The age of first attack, duration of attack, type of attack and SE classification, EEG, cranial imaging and etiology were used to analyze the influencing factors of SE prognosis. Results 75.7% were 0 ~ 6 years old in the age of first attack, and 29 cases of convulsive status epilepticus accounted for 87.9% in the classification of seizure types. There were significant differences in age of first attack, duration of attack, EEG, history of mental retardation and etiology between the two groups (P<0.05); Logistic regression analysis showed that the age of first attack, duration of attack, history of mental retardation and EEG were independent factors affecting the prognosis. Conclusion Low age, especially ≤ 6 years old, is the high incidence of SE in children at first attack. Most children are symptomatic and have obvious incentives. Convulsive SE is the main type of SE in children. The age of first onset, duration of epilepsy, history of mental retardation, and EEG can affect the prognosis of SE.
ObjectiveTo observe the dynamic changes of neuroglobin (NGB) expression in hippocampus after status epilepticus(SE) in rats, and to explore the role of NGB in epileptic seizures.Methods40 healthy male Sprague Dawley rats were randomly divided into two group according to random number table method:control group (n=5) and epilepsy model group(n=35).Epilepsy model group according to observation time was divided into:0h, 1h, 3h, 12h, 24h, 10d and 30d.Intraperitoneal injection Lithium-pilocarpine (20 mg/kg~127 mg/kg, Li-PC) to establish the rat model of SE.Observe the behavioral changes in rats with epilepsy.Nissl staining was used to detect the neuronal damage in hippocampus. Streptavidin-biotin-peroxidase complex immunohistochemical method was used to detect the expression level of NGB in hippocampus;ResultsAfter SE, the neurons in hippocampus were severely damaged with the progress of epileptic seizures, the number of surviving neurons in CA1, CA3 regions showed a near linear decline.Among them, the number of surviving neurons in (12h, 24h, 10d, 30d)CA1, (0h, 12h, 24h, 10d, 30d)CA3 and(12h, 24h, 10d, 30d) DG area were significantly lower than that of the control group (P < 0.05).The expression level of NGB in CA1, CA3 and DG region of hippocampus were increased after SE, and both of CA1 and DG were reached peak in 24h after SE, but was still higher than the control group.And the CA3 area showed a continue rising trend.Among them, CA1(24h, 10d, 30d), CA3(24h, 10d, 30d) and DG(12h, 24h, 10d, 30d) were higher than that of control group significantly (P < 0.05).In addition, it was found that there was a positive correlation between the number of surviving neurons in CA3 area and the expression level of NGB (R=0.306, P=0.011).ConclusionUp-regulation of NGB expression in hippocampus after status epilepticus, and was positively correlated with the number of neurons in the CA3 area, suggesting that up regulation of NGB expression may be a compensatory protective mechanism of ischemic injury induced by seizures, and participate in the protection of epilepsy related neuronal damage.
【摘要】 目的 探讨癫痫持续状态引起的脑部异常MRI表现的特点。 方法 回顾分析2004年—2007年5例患者由癫痫持续状态引起的脑部异常MRI表现，患者均在发作后72 h内行头颅MRI检查，常规进行了T2WI、T1WI、液体衰减反转恢复序列、弥散加权成像（diffusion-weighted imaging，DWI），同时进行了磁共振血管造影（magnetic resonance angiography，MRA）及增强扫描。 结果 5例患者均由部分性发作泛发为全面性强直-阵挛发作，均在发作后行MRI时出现明显单侧大脑半球异常表现，且与部分性发作侧相对应，在T2WI上均表现为局部皮层肿胀，呈高信号，其中3例DWI上出现皮层高信号，病灶不按脑血管分布。4例在MRA上出现病灶同侧大脑中动脉血管较对侧明显增多。5例行增强扫描后均见病灶侧脑膜明显强化。5例患者临床发作后均遗留有与MRI异常病灶相应的临床神经功能缺失。其中3例病情稳定后复查MRI，发现异常病灶及MRA完全恢复正常。 结论 癫痫持续状态引起脑部异常MRI表现特点：①常局限于大脑皮层的T2WI、DWI高信号，且病灶不按血管分布区分布；②MRA提示单侧脑血管增多；③增强扫描见单侧脑膜强化。大部分病灶可逆。这些特点可用来区别是癫痫引起的异常病灶还是脑部的致痫灶。【Abstract】 Objective To summarize the characteristics of abnormal MRI findings of brain caused by status epilepticus. Methods We retrospectively analyzed the abnormal MRI findings of brain in five patients with status epilepticus from 2004 to 2007. All of them received MRI examination within 72 hours after seizures, including the routine examination of T2WI, T1WI, FLAIR and diffusion-weighted imaging (DWI). Meanwhile, MRA and enhancement scanning were carried out. Three of them were reexamined with MRI after the disease came into a stable condition. Results All the five patients transferred from partial seizures initially to generalized tonic clonic seizures, and obvious abnormal MRI findings were detected at the unilateral cerebral hemisphere, corresponding to the side of partial seizures. They appeared regional swelling of cortex with high signal in T2WI, and three cases were found with cortex high signals in DWI, which were not distributed according to cerebral vessels. In four cases, we found that the branches of the middle cerebral artery increased markedly than the contralateral branches on the ipsilateral lesions in MRA. Enhancement scanning also showed that the meninges at the side of the lesion was strengthened significantly in five cases. The loss of neurological functions corresponding to abnormal lesions in MR remained after seizures in five cases among whom three patients recovered completely in terms of their abnormal focuses and MRA findings after their diseases came into a stable condition. Conclusions The features of abnormal brain MRI findings caused by status epilepticus are: ① High signals in T2WI and DWI are confined to the cortex, and the focuses are not distributed according to cerebral vessels; ② MRA shows that unilateral cerebral vessels increases in number; ③ Strengthened unilateral meninges can be observed in enhanced scanning and most of lesions are reversible. According the characteristics, we can distinguish the abnormal lesions caused by epilepsy from focuses in the brain causing epilepsy.
Objective To investigate the diagnosis and treatment of status epilepticus in hospitals of different levels and the knowledge of status epilepticus in clinical physicians, in order to better guide clinical education in the future. Methods From August 2014 to August 2015, a questionnaire was designed and used to investigate the general situation of the hospital, the diagnosis of status epilepticus and the clinical practice among trainee doctors and students in the epilepsy training class in the Neurological Intensive Care Unit and the Department of Neurology of West China Hospital, Sichuan University. The results of the investigation were statistically analyzed. Results Ninety questionnaires were distributed, and all the questionnaires were retrieved with validity. The number of investigated physicians was 42 (46.7%) from the Department of Neurology, 6 (6.7%) from the Department of Neurosurgery, 30 (33.3%) from the Intensive Care Unit and 12 (13.3%) from other departments. Twenty-seven (30.0%) physicians were from class Ⅲ grade A hospitals, 31 (34.4%) from class Ⅲ grade B hospitals, and 32 (35.6%) from class Ⅱ grade A hospitals. All the class Ⅲ hospitals and 53.1% of class Ⅱ hospitals had electroencephalograph monitoring facilities. The proportion of status epilepticus patients ranged from 0.5% to 10.0% in different hospitals. There were great differences in the identification and treatment of convulsive status epilepticus among different hospitals. Conclusions Status epilepticus is a common emergency. Questionnaire survey is an effective means to reflect the difference in identifying and treating the emergency among different departments and hospitals. It can guide clinical education and promote the identification and treatment of the emergency more accurately in doctors of all levels.
