伴高热惊厥史的儿童癫痌病例分析

分析伴高热惊厥史的癫痌患儿的临床特点,探讨高热惊厥脑损伤及其与颞叶癫痌的关系。 方法对1996～1999年本院儿科神经病房480例住院癫痌患儿进行回顾性分析,包括首发年龄、家族史、持续时 间、癫痌发作类型、神经影像学及脑电图改变等。结果115例(23.9％)患儿有前期高热惊厥史。伴高热惊厥史 的患儿癫痌发作早且易于出现癫痌持续状态。与无高热惊厥史的患儿相比,伴高热惊厥史的患儿强直-阵挛发作 较多,复杂部分性发作较少。408例患儿曾行影像学检查,4例提示有海马硬化者均无高热惊厥史。在伴高热惊厥史 的癫痌患儿中脑电图局灶起源的异常放电显著低于无高热惊厥史的癫痌患儿。有6.08％(7/115)伴高热惊厥史的癫 痌惠儿和6.84％(25/365)无高热惊厥史的癫痌患儿脑电图表现为单纯颞叶异常放电,二组相比无明显差异。结论 在癫痌患儿中,高热惊厥可能伴有脑损伤,且可能与后期的癫痌发生有关,伴高热惊厥史者不一定发展为颞叶癫痌。

儿童枕叶癫癎的临床及脑电图特征

目的总结儿童枕叶癫癎(COE)的临床和脑电图(EEG)特征及预后。方法对43例COE患儿的临床资料进行回顾性分析。结果起病年龄5个月-13岁;癫癎发作表现为眼球偏转20例,呕吐15例,头偏转14例,头痛10例,口咽部或手自动症9例,黑朦8例,视幻觉7例,眼睑扑动7例,眼球阵挛3例;继发半侧阵挛11例,继发全身性发作18例。头颅影像学异常15例。有明确脑损伤病史和／或头颅影像学检查证实枕叶有病变者23例,诊断为症状性COE,其余20例符合特发性COE。发作间期EEG有癎样放电41例,其中位于枕区19例,枕、后颞区15例,少数可在枕区以外。15例记录到发作期EEG。40例随访1～9 a,其中特发性19例,对抗癫癎药物疗效好,17例无复发,其中11例已停药。症状性COE对抗癫癎药物疗效欠佳,发作完全控制仅8例。结论COE发作的临床特点为跟球偏转、视觉症状、呕吐、头痛、眼睑扑动;发作间期EEG放电主要在枕区或枕、后颞区,少数可在枕区以外;特发性COE预后优于症状性COE。     

偏侧惊厥-偏瘫-癫(间)综合征的临床特点及诊断

目的探讨偏侧惊厥-偏瘫-癫癎(HHE)综合征的临床特点及诊断。方法对5例HHE综合征患儿的临床资料进行回顾性分析,总结临床特征及其发病的危险因素,进行必要的辅助检查,包括头颅CT和(或)MRI、脑电图及诊断性智力测定或精神运动发育评价。结果4例4岁内起病,3例伴热性惊厥,最长惊厥时间均在2 h以上,并惊厥侧肢体偏瘫。5例均在偏瘫后2年内出现癫癎反复发作。4例为局限性运动发作,1例为精神运动性发作。5例均存在智力障碍或精神发育迟滞。头颅MRI检查4例发现左侧海马硬化,1例CT示右半球萎缩。脑电图均异常,4例见异常放电,1例示明显不对称。5例均予卡马西平为主的药物治疗,癫癎发作得到控制或部分控制。结论HHE综合征是持续偏侧惊厥导致的偏瘫-癫癎综合征,海马硬化可能是反复癫癎所致海马的继发性损伤,而非癫癎的起源灶。应提高对该病的认识,早期正确处理惊厥持续状态将减少HHE综合征发生。     

Epilepsy and Mental Retardation Following Febrile Seizures In Childhood

ABSTRACT. In an unselected group of children who were seen following an initial febrile convulsion, the frequency of subsequent afebrile seizures was 3.5% and of mental retardation 1%. The most common afebrile seizure type was generalized major (86%). About 3/4 of the children who developed afebrile seizures did so by three years and all by five years following the initial febrile seizure. The children with afebrile seizures differed from those without afebrile seizures in the frequency of neonatal abnormality, family history of mental retardation, focal initial febrile convulsions, and delay in psychomotor milestones before the initial febrile seizure. Only about 1/3 of the children who developed afebrile seizures ever had a recurrent febrile convulsion and none had complex recurrent febrile seizures. Half the children with mental retardation had histories of delay in psychomotor milestones prior to the initial febrile seizure, and no child with mental retardation had any seizure longer than five minutes. The administration of daily phenobarbital did not reduce the frequency of epilepsy, in spite of a significant reduction in the incidence of recurrent febrile seizures. There remains no evidence that the prevention of recurrent febrile convulsions significantly decreases the frequency of afebrile seizures or mental retardation.     

Antipyretic effectiveness of acetaminophen in febrile seizures: Ongoing prophylaxis versus sporadic usage

A controlled clinical study compared the antipyretic effectiveness of acetaminophen administered at regular 4 h intervals (group 1,n=53) versus sproadic usage contingent upon a body temperature above 37.9°C (group 2,n=51) in 104 children presenting with simple febrile convulsions. The incidence of febrile episodes or temperature values were similar in spite of significantly larger amounts of acetaminophen administered to patients in group 1. Four and 4 children in groups 1 and 2, respectively, had a second episode of febrile seizures, in all of them within the first 24 h of admission. We conclude that the prophylactic administration of acetaminophen in children with febrile seizures is not effective in the prevention of fever, the reduction of its degree, or in preventing the early recurrence of febrile seizures.

目的 探讨婴儿严重肌阵挛癫癎(SMEI)的临床特点和基因诊断.方法分析13例SMEI患儿的临床和脑电图(EEG)特点及钠离子通道SCN1A基因突变筛查结果.结果男10例,女3例.8例有热性惊厥和癫痫家族史.惊厥起病年龄2～9个月,平均5.6个月.首次发作为热性惊厥9例.13例在病程早期均以反复发热诱发的全面性或一侧性阵挛或强直阵挛发作为主,其中8例有热性惊厥持续状态.出现无热惊厥的年龄为2～21个月.病程中均出现多种发作类型.发作均有热敏感的特点,诱发因素包括发热、洗热水澡和疫苗接种.起病后出现智力发育落后11例.共济失调5例,锥体束征阳性2例.EEG在1岁前多数正常,1岁后出现全导或局灶放电.头颅MBI检查异常2例.13例均应用多种抗癫痫药治疗,发作均未完全控制.卡马西平和拉莫三嗪使部分患儿发作加重.10例发现有SCN1A基因突变.结论 SMEI的临床特点是:1岁以内起病,首次发作常为热性惊厥;1岁以后出现多种发作形式和智力发育落后;发作具有热敏感的特点;EEG早期正常,以后出现全导或局灶放电.筛查SCN1A基因突变有助于早期明确诊断,指导选择抗癫癎药物.     

婴儿良性癫癎的临床观察和远期随访研究

目的 研究婴儿良性癫痫的发作特征,脑电图及治疗反应,探讨早期诊断方法。方法 对出生后3-24个月内起病,排除热性惊厥,症状性癫痫及发育异常的婴儿惊厥进行临床观察及寻像脑电图（VEEG）监测,并随访治疗效果和远期预后,结果 42例经2年以上随访确诊为婴儿良性癫痫,其中3例有良性婴儿惊厥家族史,19%惊厥伴有轻微腹泻,67%为短期内频繁发作,无癫痫持续状态,3例VEEG监测证实分别为起源于颞区,枕区及多灶性的部分性发作,发作间期脑电图背景正常,24%睡眠中有Rolandic区小棘波,39例接受抗癫痫单药治疗,平均用药时间9个月,3例未用药物治疗,起病1年内发作均消失,结论 起病早期具有以下特征应考虑有婴儿良性癫痫的可能;（1）起病年龄在3-12个月,不超过24个月,可有婴儿良性惊厥家族史;（2）发病前后精神运动发育正常;（3）发作无诱因,或仅有轻度腹泻等非特异性感染;（4）以部分性发作为主,可继发全身性发作,起病时发作可以很频繁,但无癫痫持续状态;（5）发作间期脑电图背景正常,无典型癫痫样放电,可有睡眠期Rolandic区小棘波;（6）神经影像学正常。     

Febrile convulsions and later development of epilepsy

A group of 172 epileptic children who had had prior febrile convulsions was compared with a group of 674 who had not. Children with epilepsy and prior febrile convulsions were similar in some respects (sex ratio, positive family history for seizures) to children with pure febrile convulsions and in most respects (type of epilepsy, mental status, initial EEG, and two- and four-year remission rates in the long-term outcome) to epileptic children without prior febrile convulsions. Our data do not support the current view that febrile convulsions, per se, are the main cause of mesial temporal sclerosis, le, temporal lobe epilepsy. Thus, our clinical findings support previously expressed doubts on the role of febrile seizures in temporal lobe epilepsy that were based on pathohistologic findings.     

轻度胃肠炎伴良性婴幼儿惊厥的临床研究(英文)

目的：认识轻度胃肠炎伴良性婴幼儿惊厥(BICE)的临床特点,做到正确诊断和合理治疗。方法：对年龄在3～36个月的轻度胃肠炎伴惊厥的患儿进行临床观察和出院后18个月以上的随访。结果：12例诊断为BICE,发病年龄(16.0±6.5)个月,6例(50%)冬季发病,9例(75%)3d内发生惊厥,为全身性或部分性发作,7例(58%)有早期频繁发作,一次病程中惊厥平均发作2.1次。发作间期EEG、脑影像学、血生化及脑脊液检查正常。惊厥停止后未行抗痫治疗,3例(25%)复发,复发≤2次,病程最长为8个月。所有病例精神运动发育正常。结论：本组BICE具有以下特点:1～2岁高发,冬季多发,无家族史;无热惊厥多出现于病程的早期,全身性或部分性发作,早期频繁发作多见;血电解质、血生化、脑脊液、脑影像学和发作间期脑电图正常;部分病例可复发,病程少于1年,预后好。惊厥停止后不推荐应用抗癫痫药。     

Epilepsy and mental retardation following febrile seizures in childhood

In an unselected group of children who were seen following an initial febrile convulsion, the frequency of subsequent afebrile seizures was 3.5% and of mental retardation 1%. The most common afebrile seizure type was generalized major (86%). About 3/4 of the children who developed afebrile seizures did so by three years and all by five years following the initial febrile seizure. The children with afebrile seizures differed from those without afebrile seizures in the frequency of neonatal abnormality, family history of mental retardation, focal initial febrile convulsions, and delay in psychomotor milestones before the initial febrile seizure. Only about 1/3 of the children who developed afebrile seizures ever had a recurrent febrile convulsion and none had complex recurrent febrile seizures. Half the children with mental retardation had histories of delay in psychomotor milestones prior to the initial febrile seizure, and no child with mental retardation had any seizure longer than five minutes. The administration of daily phenobarbital did not reduce the frequency of epilepsy, in spite of a significant reduction in the incidence of recurrent febrile seizures. There remains no evidence that the prevention of recurrent febrile convulsions significantly decreases the frequency of afebrile seizures or mental retardation.     

Risk of recurrent seizures after the first afebrile grand mal seizure in childhood]

A cohort of 74 children three months to 16 years-old who presented with a first unprovoked seizure were followed for five years to assess the risk of recurrence. Children with febrile convulsions, immediate posttraumatic seizures, meningitis and encephalitis were not included. The risk of recurrence was 68% for a second seizure. 47% of the patients developed an epilepsy. 85% of recurrences occurred within the first 6 months and 100% within 2 1/2 years. A history of epilepsy in a first degree relative, age at first seizure, duration of seizure, initial EEG or neurologic status were not associated with significantly higher risk of recurrence.     

Effective short-term diazepam prophylaxis in febrile convulsions

The efficacy of short-term diazepam prophylaxis in febrile convulsions was evaluated in a prospective, controlled study. A total of 289 consecutive children admitted with their first febrile seizure were randomized into two groups. One group received short-term prophylaxis for 18 months with rectally administered diazepam in solution whenever the temperature was greater than or equal to 38.5 degrees C. The control group received no prophylaxis, but diazepam rectally in the event of new seizures. The short-term prophylaxis, a mean of five doses of diazepam per child per year, afforded effective seizure control; the 18-month recurrence rate was reduced from 39% to 12% (P less than 0.001), the total number of recurrences from 77 to 23 (P less than 0.001), the long-lasting recurrences from 5.0% to 0.7% (P less than 0.05). The risk of subsequent epilepsy within the first 2 years was the same, regardless of receiving prophylaxis (3%) or not (3%); it was low after simple febrile convulsions (no cases of epilepsy in 230 children) but considerable after complex febrile seizures (20%) or seizures associated with severe interictal EEG abnormalities (50%).     

The relationship between drug treatment and the clinical characteristics of febrile seizures

Background  Drugs such as theophylline, antihistamines, and antiallergics with anti-histaminic actions have been shown to induce febrile seizures. The relationship between febrile seizures and medications has not been actively investigated. The present study aimed to investigate the relationship between the clinical characteristics of febrile seizures and the use of medications. Methods  Two hundred and sixty-five children treated at our emergency room due to febrile seizures were studied to investigate the relationship between the clinical characteristics of febrile seizures, such as the type and duration of convulsions, and the drug treatment. Results  The duration of convulsions was longer among children who took theophylline and antihistamines than among children who did not take these medications. Of the antihistamines, mequitazine did not prolong the duration of convulsion. Conclusions  Theophylline should not be used in febrile children, particularly infants. Cautions should be taken in using histamine H1 antagonists in young infants because such drugs could potentially disturb the anticonvulsive central histaminergic system. However, mequitazine appears to be a suitable antihistamine for use in children with febrile seizures, since it does not prolong convulsions.     

Seizures in children after kidney transplantation: Has the risk changed and can we predict who is at greatest risk?

Abstract:  Children undergoing kidney transplantation are at increased risk for symptomatic seizures with a previously reported incidence of approximately 20%. Little data exist to help predict which children may be at risk. We retrospectively reviewed all children who underwent kidney transplantation evaluation at our center between October 1993 and August 2007 and identified 41 children who had an EEG prior to transplant. Demographic data as well as the following were collected: immunosuppressive medications, developmental status, history of seizures, family history of seizures, post-transplant seizures and EEG results. EEGs were classified as normal or abnormal. Prior to transplantation, one child had a history of febrile seizures and six experienced afebrile seizures. Nine (22%) children identified had an abnormal EEG prior to transplant. In eight cases the EEG was non-epileptiform and in one case was epileptiform. Abnormal EEGs did not correlate with a family history of seizures. Delayed development was noted in seven children and was not associated with an epileptiform EEG. Following kidney transplantation, no child experienced a seizure. Our single center study suggests that current rates of seizures following kidney transplantation are lower than previously reported and that routine EEG as part of the pretransplant evaluation in these children is of limited use to predict those at risk.

Abstract：

Objective To summarize the electroclinical characteristics of myoclonic atonic epilepsy (MAE) in children. Method The clinical data, video electroencephalogram (EEG) and simultaneous electromyography (EMG) of MAE patients were analyzed. The treatment and its effects were followed up.Result In 47 MAE patients, 25 had a history of febrile seizures ( FS), 20 had a family history of FS or epilepsy. All patients had a normal development before the illness. The age of afebrile seizure onset was between 1.4 years to 5.8 years. The first seizure was generalized tonic-clonic seizure (GTCS) in 41 patients (87.2%). All patients had multiple seizure types, including 47 GTCS (97.9%), 34 myoclonic atonic seizures (72. 3% ), 47 myoclonic seizures ( 100% ), 32 atonic seizures (68. 1% ), 36 atypical absences (76. 6% ) and 3 tonic seizures (6. 4% ). EEG backgrounds were slow or parietal θ rhythm, interictal EEG showed 1-4 Hz (predominant 2-3 Hz) generalized spike and wave or poly spike and wave discharges in all cases. Seizures were controlled by antiepileptic drugs (AEDs) in 41 patients (87.2%). Valproate was used in 37. Lamotrigine was used in 26. Mild mental retardation was observed in 10 children after the onset of the illness. Conclusion The clinical features of MAE included the following: the development was normal before the onset of the illness; the onset of seizure type was often GTCS. All patients had multiple generalized seizure types. Myoclonic atonic seizure was its characteristic seizure type. EEG showed generalized discharges. Early diagnosis and rational choice of AEDs are important for getting a better prognosis.     

Role of early EEG and neuroimaging in determination of prognosis in children with complex febrile seizure

BACKGROUND: The present study investigates the role of early use of EEG in children with no known neuropathology prior to the first CFS, and the contribution made by computed tomography (CT) and magnetic resonance imaging (MRI) to treatment and prognosis. METHODS: Over a period of 7 years, the authors evaluated 159 children (age range: 2 months-5 years) who were being treated for CFS at Haydarpasa Numune Training and Research Hospital, Pediatrics Clinic, Istanbul, Turkey, and who had no previously known neurological disorder. Patients who presented with febrile seizure were determined to have CFS if they fulfilled the following criteria: <3 months of age when seizure occurred, duration of seizure >/=15 min, more than one seizure occurred during a single episode of illness, or focal seizures and postictal neurological deficit was found. EEG was performed on all patients. CT was performed on the patients who had postictal neurologic deficit or focal seizures. Cranial MRI was performed on patients who had focal findings in their EEGs. RESULTS: Electroencephalogram abnormality was found in 71 cases; 51 of these were diagnosed with epilepsy during follow up. Six of the 16 cases whose EEGs were abnormal between days 2 and 6 were diagnosed with epilepsy. Twenty of the 30 cases whose EEGs were abnormal between days 7 and 10 were diagnosed with epilepsy. All 25 cases who had abnormal EEGs after day 11 were diagnosed with epilepsy. CT was performed for 36 patients, of which five were found to have pathological changes. Pathological changes were detected in two of the nine patients who had cranial MRI. Patients who received CT or MRI were all diagnosed with epilepsy during follow up. CONCLUSION: The results suggest that if neurological examination of CFS patients are normal after their clinical status has stabilised, EEG should be performed after 7 days at the earliest, however for the most accurate diagnosis EEG should be performed 10 days after CFS. The most important predictor for neuroimaging was found to be detection of postictal neurologic deficit. MRI had no advantages over CT in first treating CFS in the emergency unit.
