Objectives The prognosis, recurrence rate and treatment of febrile seizure were studied through the research of recent western medicine and Chinese oriental medicine paper. Methods Recent western medicine paper of internal and external and chinese oriental medicine paper from 1999 to 2007 were investigated. Results and Conclusions The prognosis of febrile seizure was good in most cases, but children with febrile seizure who developed epilepsy range between 2 and 10%. The risk factors developed epilepsy including complex febrile seizure, focal and prolonged seizure, pre-existing neurodevelopmental abnormalities and recurrent febrile seizure. Recurrence rate of febrile seizure ranges between 30 and 50% was high. The risk factors can be predicted by their age at first febrile seizure happened, family medical history of febrile seizure and epilepsy, complex febrile seizure, and neurodevelopmental abnormalities. However, the most important factor of those is the age when they have first febrile seizure. Diazepam or Lorazepam was administrated for a child with prolonged seizure but only Diazepam was used for reducing recurrence of febrile seizurein febrile illness. However, there were some side effects such as lethargy, ataxia, and irritability. The study of chinese oriental medicine demonstrates that the acupuncture and venesection were used for seizure attack and reduced of recurrences and second attack. To reduce recurrence of febrile seizure, herbal medicine was also used for febrile illness or after seizure attack within a certain period of time, so reduce the recurrence, frequency of seizure and febrile illness. The most of herbs in prescription were used for removing heat and toxic meterials(淸熱解毒), extinguishing wind and to stopping the convulsion(熄風止痙)

Purpose: Febrile seizure, the most common type of pediatric convulsive disorder, is a benign seizure syndrome distinct from epilepsy. However, as epilepsy is also common during childhood, we aimed to identify the prognostic factors that can predict epilepsy in children with febrile seizures. Methods: The study comprised 249 children at the Korea University Ansan Hospital who presented with febrile seizures. The relationship between the subsequent occurrence of epilepsy and clinical factors including seizure and fever-related variables were analyzed by multivariate analysis. Results: Twenty-five patients (10.0%) had additional afebrile seizures later and were diagnosed with epilepsy. The subsequent occurrence of epilepsy in patients with a history of febrile seizures was associated with a seizure frequency of more than 10 times during the first 2 years after seizure onset (P<0.001). Factors that were associated with subsequent occurrence of epilepsy were developmental delay (P<0.001), preterm birth (P =0.001), multiple seizures during a febrile seizure attack (P =0.005), and epileptiform discharges on electroencephalography (EEG) (P =0.008). Other factors such as the age at onset of first seizure, seizure duration, and family history of epilepsy were not associated with subsequent occurrence of epilepsy in this study. Conclusion: Febrile seizures are common and mostly benign. However, careful observation is needed, particularly for prediction of subsequent epileptic episodes in patients with frequent febrile seizures with known risk factors, such as developmental delay, history of preterm birth, several attacks during a febrile episode, and epileptiform discharges on EEG.

Objectives The purpose of this study is to provide clinical evidence of Korean medicine for febrile seizure by review of randomized controlled trials on the effect of TCM (traditional Chinese medicine) for febrile seizure. Methods We searched randomized controlled trials about TCM treatment of febrile seizure from the China National Knowledge Infrastructure (CNKI) (January 2008 to June 2016). The selected literatures were assessed by Jadad scale. Results 40 papers were selected from 160 studies. Analyses of selected studies indicated that the TCM treatment group has significantly higher cure rate for febrile seizure than first aid or western medicine group. The most commonly used herbs were Gardeniae Fructus (梔子), Uncariae Ramulus cum Uncis (鉤藤), Cornus Gazeliae (羚羊角), Margarita (珍珠), Scutellariae Radix (黃芩), Glycyrrhizae Radix (甘草). The most commonly used acupoints were GV26 (人中), LI4 (合谷), KI1 (湧泉), GV20 (百會). There were no serious adverse events reported from the TCM treatment group during the treatment period. Conclusions TCM has been shown as not only effective but also safe treatment on febrile seizure. This finding can be widely utilized in clinical practice and can form the basis for development of clinical practice guidelines in future.

Purpose: Respiratory syncytial virus (RSV) infection can cause various neurological complications. This study aimed to investigate the RSV-associated neurologic manifestations that present with seizures. Methods: We retrospectively reviewed the medical records of patients aged less than 15 years with laboratory-confirmed RSV infections and seizures between January 2011 and December 2016 in a regional hospital in South Korea. Results: During this period, 1,193 patients with laboratory-confirmed RSV infection were identified. Of these, 35 (35 of 1,193, 2.93%; boys, 19; girls, 16; mean age: $20.8{\pm}16.6months$) presented with seizure. Febrile seizure was the most common diagnosis (27 of 35, 77.1%); simple febrile seizures in 13 patients (13 of 27, 48.1%) and complex febrile seizures in 14 (14 of 27, 51.9%). Afebrile seizures without meningitis or encephalopathy were observed in 5 patients (5 of 35, 14.3%), seizures with meningitis in 2 (2 of 35, 5.7%), and seizure with encephalopathy in 1 (1 of 35, 2.9%) patient. Lower respiratory symptoms were not observed in 8 patients. In a patient with encephalopathy, brain diffusion-weighted magnetic resonance imaging revealed transient changes in white matter, suggesting cytotoxic edema as the mechanism underlying encephalopathy. Most patients recovered with general management, and progression to epilepsy was noted in only 1 patient. Conclusion: Although febrile seizures are the most common type of seizure associated with RSV infection, the proportion of patients with complex febrile seizures was higher than that of those with general febrile seizures. Transient cytotoxic edema may be a pathogenic mechanism in RSV-related encephalopathy with seizures.

Purpose: Febrile seizures are induced by fever and are the most common type of seizures in children. Although numerous studies have been performed on febrile seizures, their pathophysiology remains unclear. Recent studies have shown that cytokines may play a role in the pathogenesis of febrile seizures. The present study was conducted to identify potential links between serum interleukin-1beta (IL-$1{\beta}$), tumor necrosis factor-alpha (TNF-${\alpha}$), and febrile seizures. Methods: Ninety-two patients with simple or complex febrile seizures (46 patients per seizure type), and 46 controls with comparable age, sex, and severity of temperature were enrolled. Results: The median concentrations of serum IL-$1{\beta}$ in the simple, complex febrile seizure, and control groups were 0.05, 0.1, and 0.67 pg/mL, respectively (P=0.001). Moreover, the median concentrations of TNF-${\alpha}$ in the simple, complex febrile seizure, and control groups were 2.5, 1, and 61.5 pg/mL, respectively (P=0.001). Furthermore, there were significant differences between the case groups in serum IL-$1{\beta}$ and TNF-${\alpha}$ levels (P<0.05). Conclusion: Unlike previous studies, our study does not support the hypothesis that increased IL-$1{\beta}$ and TNF-${\alpha}$ production is involved in the pathogenesis of febrile seizures.

Purpose: Electroencephalography (EEG) is frequently ordered for patients with febrile seizures despite its unclear diagnostic value. We evaluated the prevalence of abnormal EEGs, the association between clinical findings and abnormal EEGs, and the predictive value of EEG for the recurrence of febrile seizures Methods: Data were collected on 230 children who were treated for febrile seizures at Kyung Hee University Medical Center from 2005 to 2009. EEGs were recorded after 1-2 days of hospitalization when children became afebrile. EEG patterns were categorized as normal, epileptiform, or nonspecific relative to abnormalities. The patients' medical records were reviewed, and telephone interviews with the families of the children were conducted to inquire about seizure recurrence. The relationships between clinical variables, including seizure recurrence, and EEG abnormalities were evaluated. Results: Of the 131 children included, 103 had simple and 28 had complex febrile seizures. EEG abnormalities were found in 41 children (31%). EEG abnormalities were more common in children with complex than simple febrile seizures (43% vs. 28%), but the difference was not statistically significant. Logistical regression analysis showed that having multiple seizures in a 24-hour period was significantly predictive of abnormal EEG (odds ratio, 2.98; 95% confidence interval, 1.0 to 88; P =0.048). The frequency of recurrence did not differ significantly in the normal (31%) and abnormal (23%) EEG groups. Conclusion: Multiple seizures within 24 hours were predictive of abnormal EEG in children with febrile seizures. Abnormal EEG was not predictive of febrile seizure recurrence.

Febrile seizure (FS) is the most common seizure disorder of childhood, and occurs in an age-related manner. FS are classified into simple and complex. FS has a multifactorial inheritance, suggesting that both genetic and environmental factors are causative. Various animal models have elucidated the pathophysiological mechanisms of FS. Risk factors for a first FS are a family history of the disorder and a developmental delay. Risk factors for recurrent FS are a family history, age below 18 months at seizure onset, maximum temperature, and duration of fever. Risk factors for subsequent development of epilepsy are neurodevelopmental abnormality and complex FS. Clinicians evaluating children after a simple FS should concentrate on identifying the cause of the child's fever. Meningitis should be considered in the differential diagnosis for any febrile child. A simple FS does not usually require further evaluation such as ordering electroencephalography, neuroimaging, or other studies. Treatment is acute rescue therapy for prolonged FS. Antipyretics are not proven to reduce the recurrence risk for FS. Some evidence shows that both intermittent therapy with oral/rectal diazepam and continuous prophylaxis with oral phenobarbital or valproate are effective in reducing the risk of recurrence, but there is no evidence that these medications reduce the risk of subsequent epilepsy. Vaccine-induced FS is a rare event that does not lead to deleterious outcomes, but could affect patient and physician attitudes toward the safety of vaccination.

Purpose: Febrile seizures (FS) are seizures that occur between the age of 6 and 60 months, but its pathophysiology still is not fully understood. There is limited information about the correlation between levels of selenium and leptin with FS. This study aimed to determine the relationship between serum levels of selenium and leptin in children with FS. Methods: This case-control study was conducted in a University Hospital in Shahrekord, Iran, in 2011. The serum levels of selenium and leptin of 25 children with simple febrile seizure (case group) were compared with 25 febrile children without seizure (control group) in acute phase and after three months. The levels of serum selenium and leptin were measured by flame atomic absorption spectrophotometer and enzyme-linked immunosorbent assay method, respectively. Results: In acute phase, the mean serum level of selenium in case and control groups were $95.88{\pm}42.55$ and $113.25{\pm}54.43{\mu}g/dL$, respectively, and difference was not significant (P=0.415), but after three months, this level had a significant increase in both groups (P<0.001). In acute phase, the mean serum leptin level in case and control groups were $0.94{\pm}0.5$ and $0.98{\pm}0.84$ ng/mL, respectively, but difference was not significant (P=0.405). After three months, serum leptin level had no significant change in both groups (P=0.882). Conclusion: These observations suggest that serum levels of selenium and leptin have not specific relation with FS but overllay is lower, however, further study is recommended. Also selenium level in stress and acute phase was significantly lower than recovery phase.

목 적: 열성 경련은 6개월에서 5세사이 소아의 2-5%가 경험하게 되는 소아과 영역에서 가장 흔한 신경계 질환으로, 열성 경련 환아 중 30-50%가 재발을 경험한다. 열성 경련의 재발을 증가시키는 위험인자들에 대한 연구들은 많이 되어 있으나, 여러 위험인자들이 재발에 관계되어 일관된 결과를 나타내지 않기 때문에 개개 위험인자에 따른 분석보다는 여러 인자들을 조합해 재발률이 높은 환자군을 가려내어 이들에게 예방적 항경련제를 투여하는 것이 효과적이라 하겠다. 따라서 저자들은 열성 경련 재발의 위험인자들을 알아 보고, 나아가 의의있는 인자들을 조합하여 재발률이 높은 군을 가려냄으로써 열성 경련의 재발을 예방하기 위한 항경련제 투여를 결정하는 데 도움이 되고자 하였다. 방 법: 1997년 3월부터 1999년 7월까지 2년 5개월동안 본원에 열성 경련으로 입원한 환자 중 최소 2년이상 외래에서 추적 관찰이 가능했던 204명을 대상으로 하여 성별, 첫 열성 경련의 발생 연령, 열성 경련과 간질의 가족력 유무, 첫 경련의 형태, 신경학적 이상 유무, 뇌파의 이상 유무 등에 따라 재발률을 조사, 비교하였다. 그리고 통계적으로 유의하였던 재발의 위험인자들을 조합하여 재발률을 조사하였다. 결 과 : 1. 위험인자별 재발률 첫 열성 경련의 발생 연령이 12개월 이전이었던 68명 중 48명(70.5%)에서 재발하여, 12개월 이후에 첫 경련이 있었던 군(66/136명, 48.5%)에 비해 재발이 유의하게 많았다(P=0.0027). 사촌이내에 열성 경련의 가족력이 있는 52명 중 39명(75.0%)이 재발하여, 가족력이 없는 군(75명/152명, 47.5%)에 비해 재발이 유의하게 많았다(P=0.0006). 성별, 간질의 가족력, 첫 열성 경련의 형태, 첫 경련전 신경계 발달 이상, 뇌파의 이상 등은 열성 경련의 재발을 증가시키지 못했다. 2. 유의한 재발인자들의 조합에 따른 재발률 열성 경련의 가족력과 첫 열성 경련의 발생 연령이 재발의 위험인자로 유의하였으므로 이들 인자들을 조합하여 재발률을 조사하였다. 1) 첫 재발률 열성 경련의 가족력이 없고 첫 경련시기가 12개월 이후였던 경우(위험인자가 없는 경우)는 43.8%에서 재발이 일어났다. 열성 경련의 가족력이 없고 첫 경련의 시기가 12개월 이전이었던 경우(위험인자가 하나)는 61.7%에서 재발이 일어났다. 열성 경련의 가족력이 있으면서 첫 경련의 발생이 12개월 이후였던 경우(위험인자가 하나)는 64.5%에서 재발이 일어났다. 열성 경련의 가족력이 있으면서 12개월 이전에 첫 경련이 있었던 경우(두가지 위험인자를 모두 가진 경우)는 90.4%에서 재발이 일어났다. 2) 두 번째 재발률 위험인자가 없는 경우는 18.1%, 하나인 경우는 44.7%, 54.9%였고, 두가지 위험인자를 모두 가진 경우는 81.0%의 높은 재발률을 보였다. 결 론 : 열성 경련의 가족력과 첫 열성 경련의 발생연령(12개월 미만)이 열성 경련 재발의 의미있는 위험인자이었고, 인자 조합시 유의한 재발인자의 수가 많아지면 재발률도 증가하였다. 열성 경련의 가족력이 있으면서 12개월 이전에 첫 열성 경련이 있었던 환아들은 재발률이 90%나 되는 고위험군에 속하였다.

목적: 열경련 환자의 경우 대부분 좋은 예후를 보이며 비열성 발작으로 가는 비율은 2-7%로 알려져 있다. 열경련이 6세 이후에도 지속되거나 새로 발생하는 경우 비열경련으로 가는 비율이 일반 열경련 환자에 비해 높은 것으로 알려져 있지만, 위험인자에 대해서는 알려진 바가 없다. 6세 이후 열경련에 대한 연구는 소수에서만 진행이 되었으며, 6세 이후 열경련 환자에 대한 비열성 발작의 위험인자를 알아보고자 하였다. 방법: 2011년 1월부터 2017년 6월까지 열경련으로 소아청소년과 신경분과 외래를 방문한 환자를 대상으로 하였으며, 그중 6세 이후에도 열경련이 지속되거나 새로이 발생한 환자들을 연구 대상으로 하였다. 정보 수집은 차트 리뷰 및 전화 조사를 통하여 시행하였다. 76명의 환자가 최종 연구 대상으로 선정되었으며, 비열성 발작으로 가는 위험 인자를 확인하기 위하여 로지스틱 회귀분석을 시행하였다. 결과: 열경련으로 방문한 896명의 환자 중, 83명에서 6세 이후에 열경련이 발생하였다. 이 중 3명은 뇌파 이상 소견 및 지속되는 열경련으로 항경련제를 복용하였고, 4명은 6세 이전에 비열성 발작이 최소 1회 이상 발생하여 연구 대상에서 제외하였다. 최종 76명이 연구 대상으로 선정되었다. 열경련의 시작 나이를 6세 기준으로 나누었을 때, 6세 전에 열경련이 시작된 군에서 열경련 가족력 및 복합열경련의 빈도가 높게 보고 되었으나, 이외 뇌파 검사 및 다른 주요 임상 변수들은 통계적인 차이를 보이지 않았다. 21%(16/76)에서 추후 비열성 발작이 발생하였으며, 비열성 발작으로의 진행에 영향을 주는 독립 인자로 뇌파 이상 소견이 확인되었다. 결론: 6세 이후 열경련 군에서 열경련의 시작 나이는 특별한 임상적인 의미를 갖지 않았다. 뇌파 이상 소견이 있는 경우 비열성 발작으로 가는 비율이 통계적으로 의미 있게 높게 나타났다. 6세 이후 열경련 환자에서 예후를 예측하는데, 뇌파 시행은 의미 있는 검사 방법이 될 수 있겠다.
