ObjectiveTo study the clinical and EEG features, therapeutic response and prognosis of eyelid myoclonia-nonconvulsive status epilepticus (EM-NCSE) in children.MethodsCollected the clinical and EEG data of 3 children with EM-NCSE that were diagnosed in department of neurology in Qilu Children Hospital of Shandong university during the January in 2015 to August in 2016.Analysed the therapeutic response to antiepletic drugs(AEDs).ResultsAmong the three children, there were 2 girls and 1 boy.The age at the onset of the disease was from 6 to 10 years old.The average age of them is 8.67 years old.The clinical manifestations include mental confusion, dysphoria, winking and scrolling up the eyes.The typical vedio electroencephalography (VEEG) in the patients showed 3~6 Hz generalized spike and waves and polyspikes burst, especially in the frontal and the anterior temporal region.In addition, the eye closure and intermittent photic stimulation helped to induce discharges and clinical events as eyelid myoclonia (EM).ConclusionsEM-NCSE is one of the idiopathic and generalized epileptic disease and characterized by EM.Video EEG monitoring plays an important role in the diagnosis of this disease.The drugs of choice for treatment was diazepam.When the event was controlled, AEDs were effective for the following therapy.
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.
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.
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.
ObjectiveTo analyze the prognosis factors in status epilepticus and confirm the external validity of the Status Epilepticus Severity Score (STESS) prediction functions for outcome in patients with statusepilepticus. MethodsRetrospectively, collecting prognosis factors in status epilepticus of 50 patients. These factors include gender, age, SE aetiology, seizure type at SE onset, history of prior seizures or epilepsy, level of consciousness, duration of SE, albumin and infection. Using STESS score to evaluate the prognosis of patients, then evaluate the effectiveness of the STESS score. Results1. Single factor analysis:age,history of prior seizures or epilepsy, level of consciousness and infection were prognosis factors in status epilepticus (P<0.05). Gender, SE aetiology, seizure type at SE onset and albumin were not prognosis factors (P>0.05). Multivariablelogistic regression models selected two factors:duration of SE (OR3.645), level of consciousness (OR2.877). 2. 28 status epilepticus patient in the STESS 0-2 group were all alive. 10 status epilepticus patients in the STESS 3-6 group were died (45.4%), 12 patient were alive (54.6%). There were significant differences among the prognostic of patienst in different groups (P<0.01). The receiver operating characteristic curve for prediction of death by the STESS Score had an area under the curve of 0.92. The optimal cut-off point is 3. ConclusionAge, history of prior seizures or epilepsy, level of consciousness, duration of SE and infection were prognosis factors in status epilepticus. Level of consciousness and duration of SE were the directly related factors of the prognosis of status epilepticus. STESS score performed reasonable prognositic role on our patients with status epilepticus.
Objective To study the factors that affect the prognosis of status epilepticus (SE) and to improve the understanding of clinicians. Methods A retrospective analysis of 57 patients with SE witch from the General Hospital of Ningxia Medical University and Cardio-cerebrovascular Disease Hospital were carried out to collect their clinical data. The data were analyzed by SPSS 17.0 software. The prognosis of the patients was assessed by the Status epilepticus severity score (STESS) scale. Results A total of 57 patients were included, 53 cases improved, 4 cases were automatically discharged. Telephone follow-up showed that 4 cases of automatic discharge were dead. The mortality rate of SE was 7.02%. The most common cause of SE was acute cerebrovascular disease (17.54%), followed by intracranial infection (10.53%); The most common incidence were the occasional medication, self-medication, withdrawal (15.79%). Age, state of consciousness and concurrent infection were associated with prognosis (improvement/death) (P<0.05). STESS score of 0 to 2 points were 45 patients, all improved; score of 3 to 5 points were 12 patients, 8 patients improved, 4 patients died. There were significant differences in the prognosis between the two groups (P<0.05). Conclusions Age, state of consciousness, concurrent infection were related to prognosis, more than 65 years, the state of consciousness for the sleeping or coma had the poor prognosis. STESS scale can predict the prognosis of patients effectively.
ObjectiveTo summarize the clinical phenotype, electrophysiological characteristics, imaging characteristics, surgical treatment and prognosis of Rasmussen encephalitis (RE), so as to deepen the understanding of the disease. MethodsThe clinical data of patients with RE who underwent surgical therapy from October 2014 to October 2019 at Children's Epilepsy Center in Peking University First Hospital were retrospectively reviewed. Demographic characteristics, seizure forms, electroencephalogram (EEG), cranial nuclear magnetic resonance (MRI), operative methods as well as surgical outcomes evaluated by Engel classification during follow-up of the subjects were collected and analyzed. ResultsTotally 21 pediatric patients were enrolled, including 8 males and 13 females. The age at onset was (5.0±2.0) years old, the age at the time of surgery was (6.9±2.7) years old, and the disease duration at the time of surgery was (1.7±1.3) years. Twenty (20/21, 95.2%) patients had focal motor seizures, and 10 (10/21, 47.6%) patients had 2 or 3 forms of focal motor seizures. Fifteen patients (15/21, 71.4%) had epilepsia partialis continua (EPC), which occurred (0.7±0.6) years after the onset. All patients had hemiplegia, which appeared at (0.9±0.6) years after the onset. All patients showed a slow rhythm at their affected hemispheres during the EEG monitoring and 4 of them also showed slow rhythm at the contralateral hemispheres as the disease progressed. All patients had epileptiform discharges at the involved hemisphere, and 6 patients also had independent epileptiform discharges on the contralateral side. All 21 patients underwent hemispheric disconnection. The duration of follow-up was 2 to 7 years, and all patients achieved Engel class I after the surgery. The neurological dysfunction recovered to varying degrees during the postoperative period. ConclusionRE mostly occurs around the school age. Focal motor seizures are the main manifestations and the most common onset symptoms. With the progress of the disease, the condition of patients worsened gradually. The EEG of patients was mainly characterized by broad slow wave and spike wave in the affected hemisphere. Some patients can also have bilateral involvement, which was obviously asymmetrical. Through surgical treatment, the patients all achieved good results in terms of seizures and development.
