Abstract
Several potential risk factors have been identified in the etiopathogenesis of febrile seizures (FS), including the type and extent of breastfeeding (BF). Given the lack of conclusive data, this study aims to systematically evaluate the evidence on the association between BF and FS. We conducted a systematic review and meta-analysis according to PRISMA guidelines. The search was conducted using descriptors for FS, BF, and formula feeding in MEDLINE, Embase, and Web of Science databases. We included observational studies that compared the incidence of FS between those who had ever breastfed and those who were formula fed. The study protocol was registered on the PROSPERO platform under the number CRD42023474906. A total of 1,893,079 participants from 8 datasets were included. Our main analysis showed no significant association of any type of BF on the incidence of FS compared with formula-fed children (OR: 0.84; CI: 0.67-1.04; I2 = 78%; Cochran's Q = 0.0001), although meta-regression showed that BF was associated with a lower incidence of FS in preterm infants. Our secondary outcome showed a significantly reduced incidence of FS in children who received BF exclusively (OR: 0.80; CI: 0.65-0.99; I2 = 70%; Cochran's Q = 0.02). Conclusion: There was no significant reduction in the incidence of FS in those who were breastfed compared to formula feeding. However, our meta-regression analysis indicated an association between BF and a lower incidence of FS in preterm infants. Additionally, children who exclusively received BF had a significantly reduced incidence of FS. These findings should be further investigated in prospective cohorts. What is Known: • Breastfeeding can modify risk factors for febrile seizures, such as susceptibility to viral and bacterial infections, micronutrient deficiencies, and low birth weight. • However, studies have shown conflicting results regarding the impact of breastfeeding on febrile seizures. What is New: • When comparing any breastfeeding pattern with no breastfeeding, there is no significant difference in the incidence of febrile seizures. • When comparing exclusive breastfeeding with no breastfeeding, there may be a decrease in the occurrence of febrile seizures.

Abstract
BACKGROUND Many clinical evidences have reported the higher risk of seizure in young children and infants after exposure to hyperthermia, which more likely can cause brain damage and affect cognitive function, so, many researches were focused on prevention or treatment of febrile seizure (FS) with minimal adverse effects. Considering the potential effects of oxidative stress as a prominent trigger in FS, and demonstrating the anti-oxidant effects of metformin, the present study aimed to investigate the protective effect of metformin administration in prenatal and lactation periods in rat pups exposed to hyperthermia by which induced seizure. METHOD AND MATERIALS Pregnant rats were divided into six groups: (1) vehicle: pregnant rats received normal saline during pregnancy and lactation; (2) FS: pregnant rats received normal saline during pregnancy and lactation; (3-5) FS-Met50/100/150 mg/kg: pregnant rats received different doses of metformin including 50, 100 and 150 mg/kg during pregnancy and lactation; (6) Met150 mg/kg: pregnant rats received Met150 mg/kg during pregnancy and lactation. The male pups born to mothers received in all FS groups exposed to hyperthermia. All experimental groups were allowed to grow up, and after the lactation period, they were subjected for behavioural tests and biochemical analysis. RESULTS According to the present findings, the prenatal and lactation exposure to the highest dose of metformin demonstrated significant difference with FS group in both behavioural and biochemical test analyses. Although the remaining doses of metformin were also effective, the much better results were reported with the highest dose of metformin (150 mg/kg). Interestingly, the highest dose of metformin administered alone demonstrated better result than vehicle in probe trial test. CONCLUSION Considering the present research and related study in relation to metformin in ameliorating the epilepsy symptoms, there are numerous evidences on positive effect of metformin on seizure. Although the exact mechanism is unclear, the anti-oxidant effect of metformin is strongly supported.

Abstract
BACKGROUND SARS-CoV-2 posed a threat to children during the early phase of Omicron wave because many patients presented with febrile seizures. The study aimed to investigate predicting factors for acute encephalopathy of children infected by SARS-CoV-2 Omicron variant presenting with febrile seizures. METHODS The retrospective study analyzed data from pediatric patients who visited the emergency department of Chang Gung Memorial Hospital in Taiwan between April and July 2022. We specifically focused on children with COVID-19 who presented with febrile seizures, collecting demographic, clinical, and laboratory data at the pediatric emergency department, as well as final discharge diagnoses. Subsequently, we conducted a comparative analysis of the clinical and laboratory characteristics between patients diagnosed with acute encephalopathy and those with other causes of febrile seizures. RESULTS Overall, 10,878 children were included, of which 260 patients presented with febrile seizures. Among them, 116 individuals tested positive for SARS-CoV-2 and of them, 14 subsequently developed acute encephalopathy (12%). Those with acute encephalopathy displayed distinctive features, including older age (5.1 vs. 2.6 years old), longer fever duration preceding the first seizure (1.6 vs. 0.9 days), cluster seizure (50% vs. 16.7%), status epilepticus (50% vs. 13.7%) and occurrences of bradycardia (26.8% vs. 0%) and hypotension (14.3% vs. 0%) in the encephalopathy group. Besides, the laboratory findings in the encephalopathy group are characterized by hyperglycemia (mean (95% CI) 146 mg/dL (95% CI 109-157) vs. 108 mg/dL (95% CI 103-114) and metabolic acidosis (mean (95% CI) pH 7.29(95% CI 7.22-7.36) vs. 7.39 (95%CI 7.37-7.41)). CONCLUSIONS In pediatric patients with COVID-19-related febrile seizures, the occurrence of seizures beyond the first day of fever, bradycardia, clustered seizures, status epilepticus, hyperglycemia, and metabolic acidosis should raise concerns about acute encephalitis/encephalopathy. However, the highest body temperature and the severity of leukocytosis or C-reactive protein levels were not associated with poor outcomes.

Abstract
BACKGROUND While generally self-limited, febrile seizures result in significant familial distress. Ambulatory pediatric care providers must be prepared to counsel families on the causes, risk factors, management principles, and prognosis of children with febrile seizures. OBJECTIVE To provide an updated, evidence-based review of febrile seizures focused on the needs of an ambulatory pediatric care provider. METHODS A narrative review of the literature prioritizing landmark articles, metanalyses, longitudinal population longitudinal cohort studies and national level guidelines. RESULTS Febrile seizures are aberrant physiological responses to fever in children caused by complex interactions of cytokine mediated neuroinflammation, environmental triggers, and genetic predisposition. Other than investigations to determine fever etiology, routine bloodwork, lumbar punctures, neuroimaging and electroencephalograms are low yield. The general prognosis is excellent, however, clinicians should be aware of long-term outcomes including: cognitive impairment with non-simple febrile seizures; neuropsychiatric associations; recurrent febrile seizure and epilepsy risk factors; and the association between complex febrile seizures and sudden unexpected death. Children with a high risk of recurrence, complex febrile seizures, limited access to care, or extreme parental anxiety may benefit from intermittent oral diazepam prophylaxis. CONCLUSION Clinicians should consider four management priorities: 1) terminating the seizure; 2) excluding critical differential diagnoses; 3) investigating fever etiology; and 4) providing adequate counselling to families. The clinical approach and prognosis of febrile seizure can be based on subtype. Children with non-simple (i.e. complex or febrile status epilepticus) febrile seizures require closer care than the vast majority of children with simple febrile seizures, who have excellent outcomes.

Abstract
The study of children who experienced with febrile seizures(FS) as a result of COVID-19 infection to gain insight into the clinical characteristics and prognosis of neurological damage, with the aim of improving prevention, diagnosis, and the treatment of neurological complications. This study investigated the clinical features of 53 children with FS who were admitted to Sanya Women and Children's Hospital from December 1, 2022, to January 31, 2023. The results indicated that the duration of convulsion in the case and control group was 7.90±8.91 and 2.67±1.23 (minutes) respectively. The analysis reveals that convulsions occurred within 24 hours in 39 cases (95.12%) of the case group, and in 8 cases (66.7%) of the control group. The difference was statistically significant (P<0.05). Additionally, the case group presented lower counts of WBC and NEU compared to the control group (p<0.05). The findings indicate that convulsions manifest at earlier stages of COVID-19 in children and the last longer than in the control group. It is therefore crucial for healthcare workers to remain attentive to patients with COVID-19 who report fever within 24 hours, and act promptly to implement preventive measures, particularly in cases of prolonged fever. It is essential to integrate the clinical manifestation, particularly convulsions, and the continuous numerical changes of inflammatory factors to assess COVID-19 linked with febrile seizures. In addition, larger-scale multi-center and systematic research are necessary to aid clinicians in monitoring neuropathological signals and biological targets, enabling more equitable diagnosis and treatment plans.

Abstract
The purpose of this study is to develop a prediction nomogram of recurrent febrile seizures in pediatric children based on the identified predictors for developing recurrent febrile seizures. This is a retrospective observational study. The medical records of 320 febrile seizure-afflicted children admitted to Zhoushan Women and Children Hospital from March 2019 to January 2023 were retrospectively reviewed. Children were divided into the recurrent febrile seizures group and the non-recurrent febrile seizures group. The predictors of recurrent febrile seizures were identified by univariate and multivariate analyses. A prediction nomogram model was developed via R software. The performance of the nomogram was internally validated to assess the model's discrimination and consistency, and decision curve analysis was employed to assess clinical utility. There were 41 out of 320 cases that had recurrent febrile seizures during the observation period, with a 12.81% prevalence rate of recurrent febrile seizures. The predictors of recurrent febrile seizures were young age at the first febrile seizures, a family history of febrile seizures in a first-degree relative, diurnal variation of initial febrile seizures occurrence, gender, and a low level of C-reactive protein. The area under the receiver operating characteristic curve of the nomogram is 0.795 (95% confidence interval: 0.720-0.871). Calibration plots and the result of the Hosmer-Lemeshow test (P = 0.472) reveal satisfactory consistency. Decision curve analysis showed a significant net benefit of the nomogram. CONCLUSIONS The prediction nomogram model demonstrates good performance and clinical utility, which would be a convenient tool for the detection of children in pediatrics with high-risk recurrent febrile seizures. It is useful for pediatric medical staff to provide early medical interventions and family counseling. WHAT IS KNOWN • A proportion of children experience recurrences of febrile seizures. • Recognition of risk factors for recurrent FS in pediatrics would be useful for the prediction of risk probabilities and help provide tailored counseling and follow-up. WHAT IS NEW • A nomogram model is developed for risk prediction of recurrent febrile seizures in this study, which would be a convenient risk prediction tool in pediatrics. • The predictor of diurnal variation of recurrent febrile seizures is with new ideas.

Abstract
Febrile seizures, which are relatively common in young children, are often triggered by an infection and resolve quickly. Prompt presentation to a pediatric department is mandatory after any first seizure and every time for children ≤ 12 months. Central nervous system (CNS) diseases in childhood are able to cause seizures or other neurological disorders. Even the slightest suspicion of a seizure with CNS involvement must be promptly treated. In case of doubt, both an antiviral and an antibacterial treatment are started in parallel, which can be stopped after detecting the pathogen. Lumbar puncture is strictly indicated unless there are contraindications. Meningococcal sepsis is a severe clinical feature comprising high fever, chills and disorders of consciousness. The first skin symptoms are petechiae as a red flag sign. With progression, potentially lethal purpura fulminans may develop. Waterhouse-Friderichsen syndrome is a severe complication of acute bacterial meningitis. Lethality rate is 35%. The pediatric assessment triangle and the ABCDE algorithm help to identify critically ill children in a standardized, structured, and rapid manner.

Abstract
Our goal was to identify highly accurate empirical models for the prediction of the risk of febrile seizure (FS) and FS recurrence. In a prospective, three-arm, case-control study, we enrolled 162 children (age 25.8 ± 17.1 months old, 71 females). Participants formed one case group (patients with FS) and two control groups (febrile patients without seizures and healthy controls). The impact of blood iron status, peak body temperature, and participants' demographics on FS risk and recurrence was investigated with univariate and multivariate statistics. Serum iron concentration, iron saturation, and unsaturated iron-binding capacity differed between the three investigated groups (pFWE < 0.05). These serum analytes were key variables in the design of novel multivariate linear mixture models. The models classified FS risk with higher accuracy than univariate approaches. The designed bi-linear classifier achieved a sensitivity/specificity of 82%/89% and was closest to the gold-standard classifier. A multivariate model assessing FS recurrence provided a difference (pFWE < 0.05) with a separating sensitivity/specificity of 72%/69%. Iron deficiency, height percentile, and age were significant FS risk factors. In addition, height percentile and hemoglobin concentration were linked to FS recurrence. Novel multivariate models utilizing blood iron status and demographic variables predicted FS risk and recurrence among infants and young children with fever.

Abstract
Febrile seizures (FSs) are the most common cause of pediatric seizures. They are defined as seizures in children age 6 months to 5 years with a temperature higher than 100.4°F, although they are more common at higher temperatures. A family history of FS is the most common risk factor. FSs are classified into three types (simple, complex, or febrile status epilepticus) based on duration and quality, with simple FSs accounting for many cases. Most FSs persist for less than 10 minutes and are self-limiting. Approximately one-third of patients will have recurrence of FSs. Safe and effective prophylaxis for FS has yet to be identified. Most patients will not have any long-term sequelae, although there is an increased risk of epilepsy, particularly for those with febrile status epilepticus. FSs are associated with caregiver anxiety, "fever phobia," and high health care use, emphasizing the importance of education and reassurance for both the provider and family.

Abstract
BACKGROUND To investigate the relationship between the occurrence of convulsions in children and air pollution in Hangzhou. METHODS From January 1, 2018, to December 31, 2020, 775 children admitted with convulsion to the pediatric outpatient clinic of The Affiliated Hospital of Hangzhou Normal University (Hangzhou, China) were enrolled in this study. The clinical data and the corresponding weather data of the day in Hangzhou were collected and analyzed. Also, the monthly etiological classification of convulsions and the monthly average air data of Hangzhou were statistically analyzed. RESULTS The highest incidence of convulsion was observed in children 1 to 2 years old, and higher in boys than in girls. The top three main causes were febrile seizure, benign infantile convulsion with mild gastroenteritis, and epilepsy. Among the meteorological factors, the increase in the level of 2.5 micron particulate matter (PM 2.5) in the air per month led to an increase in the number of patients with febrile seizure, benign infantile convulsion with mild gastroenteritis, and epilepsy, where the increase of ozone in 8 hours (O3-8h) per month led to a decrease in the number of patients with such conditions. CONCLUSIONS PM2.5, PM10, and SO2 are the main meteorological factors affecting the occurrence of convulsions in children in Hangzhou, and PM2.5 and SO2 are risk factors. The increase in the level of PM2.5 in the air per month could increase occurrence of child convulsions, but the increase of O3-8h per month could decrease occurrence of child convulsions.

Abstract
OBJECTIVES To identify the characteristics of influenza-associated neurologic complications (INCs) in children from a recent H3N2 outbreak in Shenzhen, China during COVID-19 lockdown. METHODS A retrospective cohort study of INCs in children hospitalized with H3N2 infection was conducted. RESULTS From June 01, 2022 to July 01, 2022, 513 children with H3N2 infection were hospitalized and 97 developed INCs. Of the 18 patients with encephalopathy/encephalitis, 13 were previously healthy. Three developed acute necrotizing encephalopathy and two died. Of the 63 patients with febrile seizures, 55 (87%) had simple febrile seizures. Of the 14 patients with an exacerbation of seizure with underlying epilepsy, the seizure symptoms occurred mostly within 24 hours of disease onset (13/14). The comparison of the three groups (encephalopathy/encephalitis, febrile seizure and exacerbation of seizure with underlying epilepsy) reported no significant differences in sex, pre-existing neurologic diseases, vaccination rate, white blood cell count, C-reactive protein, procalcitonin, blood glucose, lactic acid, or duration of fever. The influenza vaccination rates were generally low (22% vs 32% vs 21%). Patients with encephalopathy/encephalitis had a higher rate of elevated alanine aminotransferase (28% vs 3% vs 0, P = 0.005). CONCLUSION H3N2-related neurologic complications in children mainly occur early in the disease course. Most patients were previously healthy and unvaccinated against influenza. Elevated alanine aminotransferase is more common in encephalopathy/encephalitis.

Abstract
Omicron generally causes milder disease than previous strains of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), especially in fully vaccinated individuals. However, incompletely vaccinated children may develop Omicron-related complications such as those affecting the central nervous system. To characterize the spectrum of clinical manifestations of neuro-COVID and to identify potential biomarkers associated with clinical outcomes, we recruited 15 children hospitalized for Omicron-related neurological manifestations in three hospitals in Hong Kong (9 boys and 6 girls aged 1-13 years). All were unvaccinated or incompletely vaccinated. Fourteen (93.3%) were admitted for convulsion, including benign febrile seizure (n = 7), complex febrile seizure (n = 2), seizure with fever (n = 3), and recurrent breakthrough seizure (n = 2), and the remaining nonconvulsive patient developed encephalopathic state with impaired consciousness. None of the seven children with benign febrile seizure and six of eight children with other neurological manifestations had residual deficits at 9-month follow-up. SARS-CoV-2 RNA was undetectable in the cerebrospinal fluid (CSF) specimens of seven patients who underwent lumbar puncture. Spike-and-wave/sharp waves affecting the frontal lobes were detected in four of seven (57.1%) patients who underwent electroencephalogram. Children with Omicron-related neurological manifestations had significantly higher blood levels of IL-6 (p < 0.001) and CHI3L1 (p = 0.022) than healthy controls, and higher CSF levels of IL-6 (p = 0.002) than children with non-COVID-19-related febrile illnesses. Higher CSF-to-blood ratios of IL-8 and CHI3L1 were associated with longer length of stay, whereas higher ratios of IL-6 and IL-8 were associated with higher blood tau level. The role of CSF:blood ratio of IL-6, IL-8, and CHI3L1 as prognostic markers for neuro-COVID should be further evaluated.

Abstract
INTRODUCTION Febrile seizures are one of the most common diseases that physicians encounter in pediatric emergency departments. Two important aspects of managing patients presenting with a febrile seizure are meningitis exclusion and co-infection investigation. This study was designed to determine any infection that occurs concomitantly with a febrile seizure episode and also to assess the frequency of meningitis among children presenting with febrile seizures. METHODS This retrospective cross-sectional study was conducted at the Children's Medical Center, an Iranian pediatric referral hospital. All patients aged 6 months to 5 years presenting with febrile seizures from 2020 to 2021 were included. Patients' data were collected from the medical report files. The presence of respiratory, gastrointestinal, and urinary infections was evaluated. Moreover, the detection of SARS-CoV-2 using reverse transcription polymerase chain reaction (RT-PCR) was performed for suspicious cases. The results of urine and stool analysis, as well as blood, urine, and stool cultures were checked. The frequency of lumbar puncture (LP) performance and its results were studied. The relationship between white blood cells (WBC), erythrocyte sedimentation rate (ESR), and C-reactive protein in meningitis was evaluated. RESULTS A total of 290 patients were referred to the Children's Medical Center, Tehran, Iran, due to fever and seizures. The mean age of the patients was 21.5 ± 13.0 months, and 134 (46.2%) were female. Out of 290 patients, 17% presented with respiratory infections. Nasopharyngeal SARS-CoV-2 RT-PCR was requested for 50 patients (17%), of which nine (3%) were reported positive and two patients had multi-inflammatory syndrome in children (MIS-C). Fever without local signs, gastroenteritis, and urinary tract infections were found in 40%, 19%, and 14% of the patients, respectively. LP was requested for 97 participants (33.4%) to evaluate central nervous system infection, of which 22 cases were suggestive of aseptic meningitis. Among laboratory tests, leukocytosis was significantly related to aseptic meningitis (odds ratio = 11.1, 95% CI = 3.0- 41.5). The blood culture testing result was positive in seven patients; all of them were due to skin contamination. CONCLUSION Evaluation of patients for possible meningitis is necessary for febrile seizure management. Although the prevalence of bacterial meningitis in these patients is not high, according to this study and other studies conducted in Iran, aseptic meningitis, especially after Measles, Mumps, and Rubella (MMR) vaccination should be considered. Leukocytosis and increased CRP can predict the occurrence of aseptic meningitis in these patients. However, further studies with a larger sample size are highly recommended. Moreover, during the COVID-19 pandemic, it is recommended to pay attention to an acute COVID-19 infection or evidence of MIS-C in children with fever and seizure.

Abstract
OBJECTIVES To study the clinical features of children with febrile seizures after Omicron variant infection. METHODS A retrospective analysis was performed on the clinical data of children with febrile seizures after Omicron variant infection who were admitted to the Department of Neurology, Children's Hospital Affiliated to the Capital Institute of Pediatrics, from December 1 to 31, 2022 (during the epidemic of Omicron variant; Omicron group), and the children with febrile seizures (without Omicron variant infection) who were admitted from December 1 to 31, in 2021 were included as the non-Omicron group. Clinical features were compared between the two groups. RESULTS There were 381 children in the Omicron group (250 boys and 131 girls), with a mean age of (3.2±2.4) years. There were 112 children in the non-Omicron group (72 boys and 40 girls), with a mean age of (3.5±1.8) years. The number of children in the Omicron group was 3.4 times that in the non-Omicron group. The proportion of children in two age groups, aged 1 to <2 years and 6-10.83 years, in the Omicron group was higher than that in the non-Omicron group, while the proportion of children in two age groups, aged 4 to <5 years and 5 to <6 years, was lower in the Omicron group than that in the non-Omicron group (P<0.05).The Omicron group had a significantly higher proportion of children with cluster seizures and status convulsion than the non-Omicron group (P<0.05). Among the children with recurrence of febrile seizures, the proportion of children aged 6-10.83 years in the Omicron group was higher than that in the non-Omicron group, while the proportion of children aged 3 years, 4 years, and 5 years in the Omicron group was lower than that in the non-Omicron group (P<0.05). CONCLUSIONS Children with febrile seizures after Omicron variant infection tend to have a wider age range, with an increase in the proportion of children with cluster seizures and status convulsion during the course of fever.

Abstract
BACKGROUND/OBJECTIVE Throughout the pandemic, febrile seizures have resulted from infection secondary to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The objective of this study is to determine if there is an increased association between COVID-19 and febrile seizures as compared with other causes of febrile seizures. METHODS This was a retrospective case control study. Data were collected from the National Institute of Health (NIH) supported National COVID Cohort Collaborative (N3C). Patients from 6 to 60 months who were tested for COVID-19 were included; cases were defined as COVID-19-positive patients whereas controls were defined as COVID-19-negative patients. Febrile seizures diagnosed within 48 hours of the COVID-19 test were considered to be associated with the test result. Patients were subjected to a stratified gender and date matching design followed by a logistic regression controlling for age and race. RESULTS During the study period, 27,692 patients were included. Of those, 6923 patients were COVID-19-positive, among which 189 had febrile seizures (2.7%). After logistic regression, the likelihood of having febrile seizures concurrently with COVID-19 as compared with other causes was 0.96 ( P = 0.949; confidence interval, 0.81, 1.14). CONCLUSIONS There were 2.7% of the patients with COVID-19 that were diagnosed with a febrile seizure. However, when subjected to a matched case control design with logistic regression controlling for confounding variables, there does not appear to be an increased risk of febrile seizures secondary to COVID-19 as compared with other causes.

Abstract
The baseline risk for multiple febrile seizures within the same febrile illness is largely unknown. Estimates range from 5 to 30%. Imprecise estimates can lead to incorrectly powering studies investigating the management of febrile seizures. To estimate the risk of multiple febrile seizures in the same febrile illness, we systematically reviewed and conducted a meta-analysis of studies from January 2000 to December 2021 that contained data for the number of children for both simple and complex febrile seizures in the same febrile illness. We searched MEDLINE, EMBASE, and Web of Science for randomized, quasi-randomized, prospective, and retrospective trials that involved children with febrile seizures. A total of 23,131 febrile illnesses with febrile seizures met the inclusion criteria. The estimated baseline risk of multiple febrile seizures in the same febrile illness was 17% (95% CI, 16-19%). However, the 30 cohorts that included both admitted and non-admitted patients had a lower percentage of multiple FSs within the same illness (14%; 95% CI, 12-15%) than the 30 cohorts that enrolled only admitted patients (20%; 95% CI, 16-25%). CONCLUSION Researchers can use estimates in this paper to design future studies. Taking into the account the substantial heterogeneity between countries and studies, clinicians could cautiously use our estimates in their clinical assessment and be better able to set parental expectations about a child's chances of having another febrile seizure during the current illness. TRIAL REGISTRATION PROSPERO CRD42020191784. Registered July 18, 2020. WHAT IS KNOWN • There is renewed interest in the diagnostic workup and prophylactic treatment of febrile seizures to prevent repeat seizures in the same febrile illness. • There is a lack of accurate estimates of the baseline risk for multiple febrile seizures in the same illness to properly design studies investigating management. WHAT IS NEW • This study provides the most robust estimates for the baseline risk for multiple febrile seizures in the same illness.

Abstract
Febrile seizures (FSs) are a common occurrence in young children and a serious concern in pediatric practice; nevertheless, the causes and mechanisms of FS are still unknown. We hypothesized a relation of neuropeptides such as neurotrophin-3 (NT-3) and growth-associated protein-43 (GAP-43) as well as zinc and the oxidant/antioxidant system with pediatric FS. The study included 100 infants categorized into 50 infants with FS and 50 febrile infants without seizures as controls. Clinical assessments, biochemical assays of NT-3 and GAP-43 using ELISA assay kits, and colorimetric measurements of TAC and Zn were performed to all participants. Overall, significant rises of the values of NT-3 and insignificant increases of GAP-43 were detected in children with FS. At the same time, zinc values and the total antioxidant capacity in serum samples were found to be decreased significantly. In addition, a negative correlation was estimated between NT-3 and zinc levels. Serum NT-3 in diagnosing febrile seizures at cutoff point > 49.62 ng/L showed 100% sensitivity, 46% specificity, positive predictive value (PPV) = 48.1%, and negative predictive value (NPP) = 100% with AUC = 0.678. Significant altered circulating NT-3 and zinc levels in FS may indicate their possible role in the pathogenesis of FS. This may open a way for further research and warrants enlightening of the pathophysiological details of FS.

Abstract
Two to five percent of infants and children experience febrile seizures (FS). Breastfeeding is beneficial to the health of mothers and children. Nevertheless, the benefits of breastfeeding in reducing FS remain unclear; thus, the present study aimed to evaluate this association. The case group was selected from 2010 to 2019, and the selected population was children younger than 5 years (i.e., children born from 2005−2019). The control group was selected from newborn infants at our hospital born between 2005 and 2019. Finally, 55 children with FS and 110 children in the control group were recruited. The results show longer breastfeeding duration is associated with an increased risk of FS (adjusted odds ratio: 1.06, 95% confidence interval: 1.01−1.11, p = 0.028). When comparing cases of FS with the control group, the percentage of inclusive breastfeeding over 12 months (32.7% vs. 9.1%, p = 0.017) and longer duration of exclusive breastfeeding were higher (10.86 ± 11.82 vs. 5.40 ± 7.17 months, p < 0.001). However, the comparison of the prevalence of FS between the different breastfeeding duration groups did not reach statistical significance. In conclusion, our study showed that a longer breastfeeding duration was associated with a higher risk of FS. Future large-scale studies evaluating the association between breastfeeding duration and febrile seizures are needed.

Abstract
Introduction: Febrile seizure is the most common convulsive event in children younger than 60 months. Fever plays an important role in causing disturbances in fluid and electrolyte balance, also hyponatremia has been thought to enhance the susceptibility to seizures. The objective of this study is to find out the prevalence of febrile seizures among children admitted to the Department of Paediatrics of a tertiary care centre. Methods: A descriptive cross-sectional study among children admitted to the Department of Paediatrics was done at a tertiary care centre between December, 2020 to September, 2021. Ethical approval was taken from the Institutional Review Committee (Reference number: 077/078-098). A total of 1052 children were included in this study. A convenience sampling technique was used. Statistical Package for the Social Sciences version 25.0 was used for data analysis. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. Results: Among 1052 children, the prevalence of febrile seizure was 100 (9.50%) (7.73-11.27 at 95% Confidence Interval). Among these 100 patients, 68 (68%) had simple febrile seizures while 32 (32%) had recurrent febrile seizures. Conclusions: The prevalence of febrile seizures was found to be higher than in other studies conducted in similar settings. This knowledge may be of practical value in advising parents or caregivers of the risk of a febrile seizure and its recurrence.

Abstract
BACKGROUND Febrile convulsion (FC) is a common seizure disorder among children aged 9 months to 5 years. It is usually benign and self-limiting with favourable prognosis. However, in Ghana, FC is commonly perceived as "not for hospital" and widely diagnosed and managed at home based on several beliefs and practices which are limited in related literature. OBJECTIVE This study explored the perceived causes and diagnosis of FC in selected rural communities in the Cape Coast Metropolis, Ghana. METHODS A descriptive phenomenological study design underpinned the study at five selected communities located not more than 2 Kilometres from the University of Cape Coast Hospital. Purposive and snowball sampling techniques were used to interview 42 participants made up of 27 parents, two grandmothers, seven registered traditional health practitioners, four herbalists, and two faith healers in the communities. The data was analysed using QSR NVivo 12. RESULTS Three perceived causes of FC were identified - biological, social/behavioural, and spiritual. Biological causes include genetic abnormalities and other underlying health conditions. The behavioural factors include poor childcare practices and nutrition. Spiritual causes include harm caused by evil spirits. The diagnosis of FC were observed prior, during and after FC attack, and these includes high body temperature, extreme body jerking, and disability outcomes respectively. CONCLUSION The perceived causes of FC are interplay of complex natural, social and spiritual factors that were deep-rooted in local socio-cultural beliefs and FC experiences. Unlike the attack stage, pre-attack diagnosis were usually missed, or misconstrued to mean other health conditions. These findings indicate the need to intensify maternal and child health (MCH) education programmes on FC in the study area through improved primary healthcare.

Abstract
BACKGROUND Malaria control remains a challenge in many parts of the Sahel and sub-Sahel regions of Africa. METHODS We conducted an individually randomized, controlled trial to assess whether seasonal vaccination with RTS,S/AS01E was noninferior to chemoprevention in preventing uncomplicated malaria and whether the two interventions combined were superior to either one alone in preventing uncomplicated malaria and severe malaria-related outcomes. RESULTS We randomly assigned 6861 children 5 to 17 months of age to receive sulfadoxine-pyrimethamine and amodiaquine (2287 children [chemoprevention-alone group]), RTS,S/AS01E (2288 children [vaccine-alone group]), or chemoprevention and RTS,S/AS01E (2286 children [combination group]). Of these, 1965, 1988, and 1967 children in the three groups, respectively, received the first dose of the assigned intervention and were followed for 3 years. Febrile seizure developed in 5 children the day after receipt of the vaccine, but the children recovered and had no sequelae. There were 305 events of uncomplicated clinical malaria per 1000 person-years at risk in the chemoprevention-alone group, 278 events per 1000 person-years in the vaccine-alone group, and 113 events per 1000 person-years in the combination group. The hazard ratio for the protective efficacy of RTS,S/AS01E as compared with chemoprevention was 0.92 (95% confidence interval [CI], 0.84 to 1.01), which excluded the prespecified noninferiority margin of 1.20. The protective efficacy of the combination as compared with chemoprevention alone was 62.8% (95% CI, 58.4 to 66.8) against clinical malaria, 70.5% (95% CI, 41.9 to 85.0) against hospital admission with severe malaria according to the World Health Organization definition, and 72.9% (95% CI, 2.9 to 92.4) against death from malaria. The protective efficacy of the combination as compared with the vaccine alone against these outcomes was 59.6% (95% CI, 54.7 to 64.0), 70.6% (95% CI, 42.3 to 85.0), and 75.3% (95% CI, 12.5 to 93.0), respectively. CONCLUSIONS Administration of RTS,S/AS01E was noninferior to chemoprevention in preventing uncomplicated malaria. The combination of these interventions resulted in a substantially lower incidence of uncomplicated malaria, severe malaria, and death from malaria than either intervention alone.

Abstract
Febrile seizures are the most common nervous system disease in childhood, and most children have a good prognosis. However, some epilepsy cases are easily induced by fever and are characterized by "fever sensitivity", and it is difficult to differentiate such cases from febrile seizures. Epilepsy related to fever sensitivity includes hereditary epilepsy with febrile seizures plus, Dravet syndrome, and PCDH19 gene-related epilepsy. This article mainly describes the clinical manifestations of these three types of epilepsy and summarizes their clinical features in the early stage of disease onset, so as to achieve early identification, early diagnosis, and early intervention to improve prognosis.

Abstract
The coronavirus 19 (COVID-19) disease, which was declared in China in December 2019, very early on became a pandemic, claiming more than 28 million victims worldwide to date. Its impact on the central nervous system is still poorly understood. The objective of this work is to assess the involvement of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in the aggravation of seizures in children known to have epilepsy and in the epileptogenesis of children hitherto seizure-free. Prior to conducting this work, we had obtained informed consent from patients and parents. We report the cases of three (3) patients, one known epileptic and the other two apparently healthy, who presented a febrile seizure in a context of COVID-19 infection. The aggravation of the epileptic seizure was indicative of a SARS-CoV-2 infection in the first patient, while the seizure occurred after induction of chloroquine sulfate treatment in the 2 other patients. Although our current concern is to limit the spread of the disease to COVID-19, it is crucial to address its possible complications. Notably, the worsening of seizures in children with epilepsy and the occurrence of first seizures in children without epilepsy following drug treatment. Equipping our COVID-19 patient management facilities with electroencephalogram (EEG) equipment could facilitate continuous electroencephalographic monitoring of children for proper management.

Abstract
BACKGROUND Low-density (LD) Plasmodium infections are missed by standard malaria rapid diagnostic tests (standard mRDT) when the blood antigen concentration is below the detection threshold. The clinical impact of these LD infections is unknown. This study investigates the clinical presentation and outcome of untreated febrile children with LD infections attending primary care facilities in a moderately endemic area of Tanzania. METHODS/FINDINGS This cohort study includes 2,801 febrile pediatric outpatients (median age 13.5 months [range 2-59], female:male ratio 0.8:1.0) recruited in Dar es Salaam, Tanzania between 01 December 2014 and 28 February 2016. Treatment decisions were guided by a clinical decision support algorithm run on a mobile app, which also collected clinical data. Only standard mRDT+ cases received antimalarials. Outcomes (clinical failure, secondary hospitalization, and death) were collected in follow-up visits or interviews on days 3, 7, and 28. After patient recruitment had ended, frozen blood from all 2,801 patients was tested for Plasmodium falciparum (Pf) by ultrasensitive-quantitative polymerase chain reaction (qPCR), standard mRDT, and "ultrasensitive" mRDT. As the latter did not improve sensitivity beyond standard mRDT, it is hereafter excluded. Clinical features and outcomes in LD patients (standard mRDT-/ultrasensitive-qPCR+, not given antimalarials) were compared with those with no detectable (ND) parasitemia (standard mRDT-/ultrasensitive-qPCR-) or high-density (HD) infections (standard mRDT+/ultrasensitive-qPCR+, antimalarial-treated). Pf positivity rate was 7.1% (n = 199/2,801) and 9.8% (n = 274/2,801) by standard mRDT and ultrasensitive qPCR, respectively. Thus, 28.0% (n = 76/274) of ultrasensitive qPCR+ cases were not detected by standard mRDT and labeled "LD". LD patients were, on average, 10.6 months younger than those with HD infections (95% CI 7.0-14.3 months, p < 0.001). Compared with ND, LD patients more frequently had the diagnosis of undifferentiated fever of presumed viral origin (risk ratio [RR] = 2.0, 95% CI 1.3-3.1, p = 0.003) and were more often suffering from severe malnutrition (RR = 3.2, 95% CI 1.1-7.5, p = 0.03). Despite not receiving antimalarials, outcomes for the LD group did not differ from ND regarding clinical failures (2.6% [n = 2/76] versus 4.0% [n = 101/2,527], RR = 0.7, 95% CI 0.2-3.5, p = 0.7) or secondary hospitalizations (2.6% [n = 2/76] versus 2.8% [n = 72/2,527], RR = 0.7,95% CI 0.2-3.2, p = 0.9), and no deaths were reported in any Pf-positive groups. HD patients experienced more secondary hospitalizations (10.1% [n = 20/198], RR = 0.3, 95% CI 0.1-1.0, p = 0.005) than LD patients. All the patients in this cohort were febrile children; thus, the association between parasitemia and fever cannot be investigated, nor can the conclusions be extrapolated to neonates and adults. CONCLUSIONS During a 28-day follow-up period, we did not find evidence of a difference in negative outcomes between febrile children with untreated LD Pf parasitemia and those without Pf parasitemia. These findings suggest LD parasitemia may either be a self-resolving fever or an incidental finding in children with other infections, including those of viral origin. These findings do not support a clinical benefit nor additional risk (e.g. because of missed bacterial infections) to using ultrasensitive malaria diagnostics at a primary care level.

Abstract
A febrile seizure is the most common type of seizure in young kids, which is not fully known. Inflammatory mediators can affect the pathogenesis of the disease. Considering the controversy about the impacts of interleukin 1 beta (IL-1β) and the lack of a study on interleukin 22 (IL-22), the purpose of the present study was to investigate the relationship between IL-22 and IL-1β serum levels with febrile seizure in young kids. Our case-control study has been conducted on 120 young kids aged 6-60 months with the sign of the fever. Rectal temperature was measured for allcases. Patients with febrile seizure (n=60) and patients with fever and without a seizure (n=60) were investigated as case and control groups, respectively. Serum levels of IL-22 and IL-1β were measured in all participants through the ELISA method. The serum level of IL-1β was significantly higher in the case group compared to the control group (p˂0.001), while there were no significant differences between the two groups in terms of IL-22 (p=0.92). Unlike IL-1β (p≤0.021), IL-22 showed no difference between two groups according to some demographic and clinical features like gender, age group, family history of febrile seizure, family history of epilepsy, and evolutionary status (p>0.22). Logistic multiple regression analysis showed that, unlike IL-1β (p˂0.001), IL-22 does not change the chance of febrile seizure in the study groups (p=0.737). The findings of this study indicated that, unlike IL-1β, IL-22 has not any changes/effects in the febrile seizure.

Abstract
BACKGROUND Measles, mumps, rubella, and varicella (chickenpox) are serious diseases that can lead to serious complications, disability, and death. However, public debate over the safety of the trivalent MMR vaccine and the resultant drop in vaccination coverage in several countries persists, despite its almost universal use and accepted effectiveness. This is an update of a review published in 2005 and updated in 2012. OBJECTIVES To assess the effectiveness, safety, and long- and short-term adverse effects associated with the trivalent vaccine, containing measles, rubella, mumps strains (MMR), or concurrent administration of MMR vaccine and varicella vaccine (MMR+V), or tetravalent vaccine containing measles, rubella, mumps, and varicella strains (MMRV), given to children aged up to 15 years. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2019, Issue 5), which includes the Cochrane Acute Respiratory Infections Group's Specialised Register, MEDLINE (1966 to 2 May 2019), Embase (1974 to 2 May 2019), the WHO International Clinical Trials Registry Platform (2 May 2019), and ClinicalTrials.gov (2 May 2019). SELECTION CRITERIA We included randomised controlled trials (RCTs), controlled clinical trials (CCTs), prospective and retrospective cohort studies (PCS/RCS), case-control studies (CCS), interrupted time-series (ITS) studies, case cross-over (CCO) studies, case-only ecological method (COEM) studies, self-controlled case series (SCCS) studies, person-time cohort (PTC) studies, and case-coverage design/screening methods (CCD/SM) studies, assessing any combined MMR or MMRV / MMR+V vaccine given in any dose, preparation or time schedule compared with no intervention or placebo, on healthy children up to 15 years of age. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the methodological quality of the included studies. We grouped studies for quantitative analysis according to study design, vaccine type (MMR, MMRV, MMR+V), virus strain, and study settings. Outcomes of interest were cases of measles, mumps, rubella, and varicella, and harms. Certainty of evidence of was rated using GRADE. MAIN RESULTS We included 138 studies (23,480,668 participants). Fifty-one studies (10,248,159 children) assessed vaccine effectiveness and 87 studies (13,232,509 children) assessed the association between vaccines and a variety of harms. We included 74 new studies to this 2019 version of the review. Effectiveness Vaccine effectiveness in preventing measles was 95% after one dose (relative risk (RR) 0.05, 95% CI 0.02 to 0.13; 7 cohort studies; 12,039 children; moderate certainty evidence) and 96% after two doses (RR 0.04, 95% CI 0.01 to 0.28; 5 cohort studies; 21,604 children; moderate certainty evidence). The effectiveness in preventing cases among household contacts or preventing transmission to others the children were in contact with after one dose was 81% (RR 0.19, 95% CI 0.04 to 0.89; 3 cohort studies; 151 children; low certainty evidence), after two doses 85% (RR 0.15, 95% CI 0.03 to 0.75; 3 cohort studies; 378 children; low certainty evidence), and after three doses was 96% (RR 0.04, 95% CI 0.01 to 0.23; 2 cohort studies; 151 children; low certainty evidence). The effectiveness (at least one dose) in preventing measles after exposure (post-exposure prophylaxis) was 74% (RR 0.26, 95% CI 0.14 to 0.50; 2 cohort studies; 283 children; low certainty evidence). The effectiveness of Jeryl Lynn containing MMR vaccine in preventing mumps was 72% after one dose (RR 0.24, 95% CI 0.08 to 0.76; 6 cohort studies; 9915 children; moderate certainty evidence), 86% after two doses (RR 0.12, 95% CI 0.04 to 0.35; 5 cohort studies; 7792 children; moderate certainty evidence). Effectiveness in preventing cases among household contacts was 74% (RR 0.26, 95% CI 0.13 to 0.49; 3 cohort studies; 1036 children; moderate certainty evidence). Vaccine effectiveness against rubella is 89% (RR 0.11, 95% CI 0.03 to 0.42; 1 cohort study; 1621 children; moderate certainty evidence). Vaccine effectiveness against varicella (any severity) after two doses in children aged 11 to 22 months is 95% in a 10 years follow-up (rate ratio (rr) 0.05, 95% CI 0.03 to 0.08; 1 RCT; 2279 children; high certainty evidence). Safety There is evidence supporting an association between aseptic meningitis and MMR vaccines containing Urabe and Leningrad-Zagreb mumps strains, but no evidence supporting this association for MMR vaccines containing Jeryl Lynn mumps strains (rr 1.30, 95% CI 0.66 to 2.56; low certainty evidence). The analyses provide evidence supporting an association between MMR/MMR+V/MMRV vaccines (Jeryl Lynn strain) and febrile seizures. Febrile seizures normally occur in 2% to 4% of healthy children at least once before the age of 5. The attributable risk febrile seizures vaccine-induced is estimated to be from 1 per 1700 to 1 per 1150 administered doses. The analyses provide evidence supporting an association between MMR vaccination and idiopathic thrombocytopaenic purpura (ITP). However, the risk of ITP after vaccination is smaller than after natural infection with these viruses. Natural infection of ITP occur in 5 cases per 100,000 (1 case per 20,000) per year. The attributable risk is estimated about 1 case of ITP per 40,000 administered MMR doses. There is no evidence of an association between MMR immunisation and encephalitis or encephalopathy (rate ratio 0.90, 95% CI 0.50 to 1.61; 2 observational studies; 1,071,088 children; low certainty evidence), and autistic spectrum disorders (rate ratio 0.93, 95% CI 0.85 to 1.01; 2 observational studies; 1,194,764 children; moderate certainty). There is insufficient evidence to determine the association between MMR immunisation and inflammatory bowel disease (odds ratio 1.42, 95% CI 0.93 to 2.16; 3 observational studies; 409 cases and 1416 controls; moderate certainty evidence). Additionally, there is no evidence supporting an association between MMR immunisation and cognitive delay, type 1 diabetes, asthma, dermatitis/eczema, hay fever, leukaemia, multiple sclerosis, gait disturbance, and bacterial or viral infections. AUTHORS' CONCLUSIONS Existing evidence on the safety and effectiveness of MMR/MMRV vaccines support their use for mass immunisation. Campaigns aimed at global eradication should assess epidemiological and socioeconomic situations of the countries as well as the capacity to achieve high vaccination coverage. More evidence is needed to assess whether the protective effect of MMR/MMRV could wane with time since immunisation.

Abstract
OBJECTIVES To determine how soon after commencement of the seasonal influenza vaccination programme, the AusVaxSafety active vaccine safety surveillance system, currently in use across Australia, would have detected a safety signal had it been operating in 2010 when there was an unprecedented number of febrile seizures in young children associated with one specific influenza vaccine brand, Fluvax (CSL Biotherapies). DESIGN Simulation study. SETTING Western Australian vaccine influenza coverage and adverse event surveillance data. OUTCOME MEASURES Simulated solicited responses from caregivers who would have received an SMS survey about adverse events experienced following seasonal influenza vaccination of their children aged 6 months to <5 years. PARTICIPANTS None. RESULTS We estimated a >90% probability of a safety signal being detected by AusVaxSafety based on solicited reports for either fever or medical attendance at or before the week ending 28 March 2010, 3 weeks after the start of vaccine distribution. Suspension of the national paediatric influenza vaccination programme as a result of the passive adverse events surveillance operating at the time did not occur until 23 April 2010. CONCLUSIONS Active vaccine safety surveillance leading to rapid detection of a safety signal would likely have resulted in earlier suspension of Fluvax from the vaccination programme, prevention of many febrile convulsions and maintenance of public confidence in influenza vaccination for young children.

Abstract
BACKGROUND Several studies have reported an association between seizure and the lunar cycle; however, results are conflicting. Thus, we investigated whether emergency department (ED) visits due to febrile seizure (FS) or FS plus were affected by lunar cycle. METHODS We reviewed the medical records of patients who were admitted to the ED with a main diagnosis of FS or FS plus from January 1, 2005 to August 31, 2018 (13 years 8 months), a period of 4991 days with 169 lunar cycles. During that period, we collected weather data such as mean temperature, average atmospheric pressure (AP), and humidity according to lunar phase (new moon, first quarter, full moon, and third or last quarter). RESULTS A total of 1979 patients were identified. We found male predominant with a mean age of 2.62 ± 2.09 years. Acute pharyngotonsillitis was the most common cause of fever, generalized tonic-clonic seizure was the most common type of seizure, and the mean peak body temperature was 38.77 ± 0.81 °C. The lunar cycle did not affect the onset or frequency of FS after adjustment; however, several factors, including season, O3 and NO2 concentrations, and holidays, were associated with FS. CONCLUSION We did not find an association between lunar cycle and FS or FS plus. However, several factors, including season, O3, NO2, and holidays were associated with FS or FS plus.

Abstract
OBJECTIVE Our study was conducted to examine the association between breastfeeding and febrile seizures (FS) in the first year of life. METHODS We used data from a birth cohort study, the Japan Environment and Children's Study (JECS). In a self-administered questionnaire, we asked participants the duration of breastfeeding and whether their children were diagnosed as having FS during their first 12 months. We estimated the association of duration and exclusiveness of breastfeeding with the FS by using multiple logistic regression analysis. RESULTS Of 84,082 children, 995 (1.2%) were diagnosed as having FS by the age of 12 months. The prevalence of FS was higher in children who were breastfed for shorter duration. Multiple logistic regression analysis showed that, compared with children breastfed for less than 1 month, those breastfed for 4-6 months and 7-12 months had lower risks of FS (adjusted odds ratio [aOR], 0.65 [95% confidence interval {CI}, 0.42-0.99]; aOR, 0.66 [95% CI: 0.45-0.96], respectively). Moreover, compared with infants who received both breast milk and formula milk for 6 months, infants who were breastfed exclusively for 6 months had lower risk of FS (aOR: 0.78 [95% CI: 0.64-0.95]). CONCLUSIONS Our results suggest that breastfeeding has a protective effect against FS in the first year of life.

Abstract
RATIONALE Seizures are rare during the perioperative period; in most cases, there is a previous history of epilepsy or surgery-associated seizures. Febrile convulsions may occur when the body temperature rises above 38°C; this is the most common cause of seizures in children. Febrile convulsions after general anesthesia in the postanesthetic care unit (PACU) without a past or family history are rare. Some reviews suggest that since anesthesia changes immunity, elective surgery should be postponed three weeks after live vaccination. PATIENT A 12-month-old female with bilateral hearing loss underwent cochlear implantation under general anesthesia. She did not have any history of convulsions or developmental disorders. However, 1 week before surgery, measles-mumps-rubella (MMR) vaccination was given as a regular immunization. DIAGNOSES Forty minutes after arrival at the PACU, sudden generalized tonic-clonic movement occurred during recovery and the patient's measured body temperature exceeded 38.0°C. INTERVENTIONS Thiopental sodium was administered intravenously as an anticonvulsant, and the tonic-clonic movement stopped immediately. Endotracheal intubation was performed to secure the airway, and tepid massage and diclofenac β-dimethylaminoethanol administration were performed to lower the patient's body temperature. OUTCOMES There was no further fever and no seizures, and no other neurological deficits were observed until discharge. LESSONS The anesthesiologist should check the recent vaccination history even if the patient has not developed particular symptoms after vaccination. It is important to know that febrile convulsions may occur in patients who have recently received MMR vaccination.

Abstract
OBJECTIVE To determine the risk factors for patients with febrile convulsions and to assess their iron status. METHODS The case-control study was conducted at the Central Child Teaching Hospital, Baghdad, Iraq, from May 1 to August 31, 2017, and comprised febrile patients aged 6-72 months admitted after presenting with axillary temperature ≥38oC. Those who got fits along with fever were declared the cases, while those with just fever were considered the controls. Venous blood samples were taken for complete blood count, biochemical tests, and for serum ferritin, serum iron and total iron binding capacity. Data was analysed using SPSS 23. RESULTS Of the 80 patients, 40(50%) were in each of the two groups. Respiratory tract infection was the commonest cause of fever in 29(58%) cases and 21(42%) controls (p>0.05). The cases were significantly younger in age (p<0.05). Also, there was significantly low haemoglobin level, low packed cell volume, low serum iron, higher total iron binding capacity and low serum ferritin in the case group (p<0.05). Iron deficiency anaemia was found in 17(73.9%) of the cases compared to 6(26.1%) among the controls. The mean serum ferritin of the cases was lower compared to the controls (p=0.001). CONCLUSIONS The risk of febrile seizure in iron-deficient children increased in the presence of risk factors.

Abstract
A febrile seizure is a seizure occurring in a child six months to five years of age that is accompanied by a fever (100.4°F or greater) without central nervous system infection. Febrile seizures are classified as simple or complex. A complex seizure lasts 15 minutes or more, is associated with focal neurologic findings, or recurs within 24 hours. The cause of febrile seizures is likely multifactorial. Viral illnesses, certain vaccinations, and genetic predisposition are common risk factors that may affect a vulnerable, developing nervous system under the stress of a fever. Children who have a simple febrile seizure and are well-appearing do not require routine diagnostic testing (laboratory tests, neuroimaging, or electroencephalography), except as indicated to discern the cause of the fever. For children with complex seizures, the neurologic examination should guide further evaluation. For seizures lasting more than five minutes, a benzodiazepine should be administered. Febrile seizures are not associated with increased long-term mortality or negative effects on future academic progress, intellect, or behavior. Children with febrile seizures are more likely to have recurrent febrile seizures. However, given the benign nature of febrile seizures, the routine use of antiepileptics is not indicated because of adverse effects of these medications. The use of antipyretics does not decrease the risk of febrile seizures, although rectal acetaminophen reduced the risk of short-term recurrence following a febrile seizure. Parents should be educated on the excellent prognosis of children with febrile seizures and provided with practical guidance on home management of seizures.

Abstract
OBJECTIVE To calculate the incidence of hospitalisation due to acute respiratory failure, pneumonia, acute respiratory distress syndrome (ARDS), febrile seizures and encephalitis/encephalopathy among influenza-positive patients in Japan, where point-of-care tests are routinely used to diagnose influenza. DESIGN A cross-sectional study using routinely collected data. SETTING Japanese clinics and hospitals between 2012 and 2016. PARTICIPANTS Japanese patients aged 0-74 years diagnosed with influenza by a rapid test in employment-related health insurance records. PRIMARY OUTCOME MEASURES Incidence of hospitalisation per 100 000 influenza-positive episodes. RESULTS We included over 16 million influenza-positive episodes, 1.0% of whom were hospitalised. Of these, 3361 were acute respiratory failure, 27 253 pneumonia, 18 ARDS, 2603 febrile seizure and 159 encephalitis/encephalopathy. The percentage of hospitalisations by age was 2.96% of patients aged 0-1 years, 0.77% aged 2-5, 0.51% aged 6-12, 0.78% aged 13-18, 1.36% aged 19-44, 1.19% aged 45-64, and 2.21% aged 65-74. The incidence of hospitalisations from these five complications combined was highest in influenza-positive patients aged 0-1 years (943 per 100 000) compared with 307 in those aged 2-5 years and 271 in those aged 65-74 years. For pneumonia, the incidence was highest for influenza-positive patients aged 0-5 years and 65 years or more. There were statistically significant decreasing trends over the years in the incidence of all-cause hospitalisations, pneumonia and febrile seizures. CONCLUSIONS Japanese administrative data revealed that 1.0% of influenza-positive patients aged under 75 years were hospitalised. Male patients had a higher incidence of pulmonary complications and febrile seizures. Children aged 0-5 years and adults aged 65-74 years were at high risk of being admitted to hospital for pneumonia.

Abstract
OBJECTIVE To investigate the association between SCN1A rs3812718 polymorphism and generalized epilepsy with febrile seizures plus (GEFS+), and to provide potential molecular targets for the diagnosis and treatment of GEFS+. METHODS The iPLEX technique in the MassARRAY system was used to determine SCN1A rs3812718 polymorphism, genotype frequency, and allele frequency in 50 patients with GEFS+ and 50 healthy controls. RESULTS As for the frequencies of CC, CT, and TT genotypes in SCN1A rs3812718, there was a significant difference in the frequency of TT genotype between the GEFS+ group and the control group (P<0.05). There was also a significant difference in the frequency of T allele between the two groups (P<0.05). Compared with those carrying CC genotype or C allele, the individuals with CT genotype , TT genotype or T allele had a higher risk of developing GEFS+ (CT/CC: OR=4.05, 95%CI: 1.04-15.69; TT/CC: OR=30.60, 95%CI: 6.46-144.85; T/C: OR=4.64, 95%CI: 2.54-8.48). CONCLUSIONS SCN1A rs3812718 polymorphism is a risk factor for GEFS+, and the population carrying T allele may have an increased risk of GEFS.

Abstract
BACKGROUND The protective value of vaccines to the public has made vaccines among the major public health prophylactic measures through the entire history. However, there has been some controversy about their safety; particularly concerns have been rising about febrile seizures (FS). Vaccination was found to be the second most common cause of FS. METHODS We research and collect relative online content for reviewing the effects of vaccine in FS. RESULTS there is no causal relationship between FS and vaccination. This relationship is complex by other factors, such as age, genetic inheritance, type of vaccine, combination of different types of vaccines and the timing of vaccination. CONCLUSION In order to reduce FS after vaccination, it is important to understand the mechanism of epilepsy and relationship between specific vaccines and FS. Parents should be informed that some vaccines could be associated with an increased risk of FS, particularly, in children with personal and family history of FS. Children with genetic epilepsy syndrome are prone to seizures and certain vaccinations should be avoided in these children. It is highly recommended to choose vaccines with lower risk of developing FS and to administer these vaccines during the low risk window of immunizations schedule.

Abstract
Levels of high mobility group box 1 (HMGB1), an important inflammatory mediator, are high in the serum of febrile seizure (FS) patients. However, its roles in FS and secondary epilepsy after prolonged FS are poorly understood. We demonstrate HMGB1's role in the pathogenesis of hyperthermia-induced seizures (HS) and secondary epilepsy after prolonged hyperthermia-induced seizures (pHS). In the first experiment, 14-15-day-old male rats were divided into four groups: high-dose HMGB1 (100 μg), moderate-dose (10 μg), low-dose (1 μg), and control. Each rat was administered HMGB1 intranasally 1 h before inducing HS. Temperature was measured at seizure onset with electroencephalography (EEG). In the second experiment, 10-11-day-old rats were divided into four groups: pHS + HMGB1 (10 μg), pHS, HMGB1, and control. HMGB1 was administered 24 h after pHS. Video-EEGs were recorded for 24 h at 90 and 120 days old; histological analysis was performed at 150 days old. In the first experiment, the temperature at seizure onset was significantly lower in the high- and moderate-dose HMGB1 groups than in the control group. In the second experiment, the incidence of spontaneous epileptic seizure was significantly higher in the pHS + HMGB1 group than in the other groups. Comparison between pHS + HMGB1 groups with and without epilepsy revealed that epileptic rats had significantly enhanced astrocytosis in the hippocampus and corpus callosum. In developing rats, HMGB1 enhanced HS and secondary epilepsy after pHS. Our findings suggest that HMGB1 contributes to FS pathogenesis and plays an important role in the acquired epileptogenesis of secondary epilepsy associated with prolonged FS.

Abstract
PURPOSE The association between iron deficiency anemia (IDA) and febrile seizures (FS) during childhood is inconclusive due to inconsistent results reported in different studies. We performed a systematic review and meta-analysis to determine an association between IDA and FS in children. METHODS We searched PubMed, EMBASE, and Cochrane Library databases for studies published up to August 2015 using the following key words: ["iron deficiency" OR "iron status"] AND ["febrile seizure" OR "febrile convulsion"] AND ["pediatric" OR "infant" OR "child"]. Pooled odds ratios (OR) and 95% confidence intervals (CI) were calculated using standard meta-analysis techniques. Subgroup analysis also was performed. RESULTS A total of 17 studies enrolling 2416 children with FS and 2387 controls were included in the meta-analysis. The results indicated that IDA was significantly associated with FS (OR, 1.98; 95% CI, 1.26-3.13; P=0.003). Subgroup analyses evaluated the diagnostic indices for IDA including serum iron, plasma ferritin, and mean corpuscular volume (MCV). The results indicated that IDA diagnosed on the basis of plasma ferritin (OR, 3.78; 95% CI, 1.80-7.94; P<0.001) or MCV (OR, 2.08; 95% CI, 1.36-3.17; P=0.001) was modestly associated with FS, whereas IDA diagnosed on the basis of two serum iron studies was not associated with FS (OR, 0.57; 95% CI, 0.24-1.37; P=0.210). CONCLUSION The results of this meta-analysis suggest that IDA is associated with an increased risk of FS in children.

Abstract
OBJECTIVE The aim of the paper was to assess the risk factors of febrile seizures in children. METHODS The paper presents an analysis of a group of 176 children aged 6 months to 5 years who were admitted to A&E because of febrile seizures. RESULTS The analysed group of 176 children comprised 61.96% boys and 38.07% girls, and the average age equalled 23 months. Family history was significant in 9.66% of patients. A statistically significant difference was noticed between insignificant family history and the incidence of febrile seizures. In all the studied groups of children the factor that determined the incidence of febrile seizures was a sudden increase in the body temperature with an infection of the upper respiratory tract of several day's duration as another cause. Febrile seizure incident was most frequently associated with a sudden increase in the body temperature in 53.40% children. A statistically significant difference was observed between persisting fever and an increase thereof during the day. Yet another factor predisposing for febrile seizures incidence was an infection of the upper respiratory system that could be observed in 32.95% patients. The mean body temperature when the seizures occurred was 38.9°C. CONCLUSIONS A sudden increase in the body temperature within the first day of pyrexia predisposes for the incidence of febrile seizures and it was proved that it depends on how long fever persists during the day. The other factor triggering the seizures was an infection of the upper respiratory tract of several days' duration.

Abstract
BACKGROUND Febrile fits is common problem in children. Among other risk factors, iron deficiency anaemia is considered as aggravating factor for febrile fits. Iron deficiency anaemia is preventable and treatable disease. The objective of the study was to find out iron deficiency anaemia as risk factor for febrile fits. METHODS It was a case control study. Thirty cases of febrile fits were recorded. Control group of 30 cases was taken at the same time with same variables but without febrile fits. Their temperatures and weights were recorded and laboratory haematological parameters haemoglobin, haematocrit, Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), Mean Corpuscular Haemoglobin Concentration (MCHC), Red Blood Count (RBC) and Red Cell Distribution Width values were collected and analysed statistically with SPSS Ver 20.0. RESULTS In case group 21 had haemoglobin <11.0 gm% while in control group 13 cases had haemoglobin <11.0 gm% (Odd Ratio 3.0513 95% CI 1.0533-8.8390) Mean Haematocrit, RBC, MCV, MCH, MCHC and RDW had statistically significant difference between the two groups (p-value <0.05). CONCLUSIONS As Iron Deficiency Anaemia is a risk factor for febrile fits, treatment and prevention of iron deficiency anaemia can decrease incidence of febrile fits.

Abstract
We report the case of a 14-month-old girl with Dravet syndrome carrying a splice-site mutation of c. 1170+1G>A on neuronal sodium channel alpha 1 subunit (SCN1A). She had a history of recurrent febrile or afebrile seizures since 4 months of age and developed acute encephalopathy due to infection with human herpesvirus-6, which presented with high grade fever, severe consciousness disturbances, and prolonged and clustered seizures. Electroencephalography showed a generalized slow activity. Intensive treatments, including mechanical ventilation, continuous thiopental infusion, and high-dose steroid therapy were initiated, and she gradually recovered. During the recovery phase, choreoathetosis-like involuntary movements appeared on the face and limbs, which were treated successfully with haloperidol. MRI findings during the acute phase were normal; however, diffuse cerebral atrophy became evident during the recovery phase. Single photon emission computed tomography (SPECT) of the brain revealed decreased cerebral perfusion over bilateral frontal and temporal lobes; however, perfusion of the occipital lobes, basal ganglia, and cerebellum remained normal. The patient showed serious developmental regression at discharge, with the loss of head control and meaningful words. Patient’s clinical course and the findings of SPECT resembled those of acute encephalopathy with biphasic seizures and late reduced diffusion (AESD), with the exception of lack of reduced diffusion of the subcortical white matter on the acute phase MRI and the prolonged and severe clinical symptoms. It has been reported that patients with Dravet syndrome are prone to complications, including various types of acute encephalopathies. Therefore, clinicians should carefully manage prolonged febrile seizures in patients with Dravet syndrome.

Abstract
Febrile convulsions affect 2-5% of children in the age group from 6 months to 5 years. The convulsions seldom have negative consequences for the child's development, but may in rare cases constitute a debut symptom of epilepsy.

Abstract
OBJECTIVE Hydrogen sulfide (H2S), as a novel gasotransmitter, plays important roles in a number of physiological and pathological processes. Its effectiveness has been demonstrated in different types of brain disorders but not in repetitive febrile seizure (febrile status epilepticus; FSE) models. This study aims to test whether a donor of H2S sodium sulfhydrate (NaHS) is also effective for FSE in rats. METHODS FSE was induced in rat pups on postnatal day 10 in water at 45.0 ± 0.1°C for 10 consecutive days with or without preadministration of NaHS. Following evaluation of the latency and duration of hyperthermic seizures, impairment in learning and memory was measured by the Morris water maze test. Moreover, alterations of the microglial response and the production of proinflammatory cytokines IL-1β and TNF-α were calculated in the hippocampus. RESULTS We found that NaHS significantly increased the latency and decreased the duration of hyperthermic seizures. Furthermore, NaHS-treated pups showed less impairment in learning and memory. In addition, NaHS inhibited FSE-induced microglial responses and suppressed the production of IL-1β and TNF-α in the hippocampus. CONCLUSION NaHS appears to be effective for the treatment of FSE in infants and children, in part due to its anti-inflammatory action.

Abstract
Despite an established link between epilepsy and sleep behavior, it remains unclear how specific epileptogenic mutations affect sleep and subsequently influence seizure susceptibility. Recently, Sun et al. (2012) created a fly knock-in model of human generalized epilepsy with febrile seizures plus (GEFS+), a wide-spectrum disorder characterized by fever-associated seizing in childhood and lifelong affliction. GEFS+ flies carry a disease-causing mutation in their voltage-gated sodium channel (VGSC) gene and display semidominant heat-induced seizing, likely due to reduced GABAergic inhibitory activity at high temperature. Here, we show that at room temperature the GEFS+ mutation dominantly modifies sleep, with mutants exhibiting rapid sleep onset at dusk and increased nighttime sleep as compared to controls. These characteristics of GEFS+ sleep were observed regardless of sex, mating status, and genetic background. GEFS+ mutant sleep phenotypes were more resistant to pharmacologic reduction of GABA transmission by carbamazepine (CBZ) than controls, and were mitigated by reducing GABAA receptor expression specifically in wake-promoting pigment dispersing factor (PDF) neurons. These findings are consistent with increased GABAergic transmission to PDF neurons being mainly responsible for the enhanced nighttime sleep of GEFS+ mutants. Additionally, analyses under other light conditions suggested that the GEFS+ mutation led to reduced buffering of behavioral responses to light on and off stimuli, which contributed to characteristic GEFS+ sleep phenotypes. We further found that GEFS+ mutants had normal circadian rhythms in free-running dark conditions. Interestingly, the mutants lacked a homeostatic rebound following mechanical sleep deprivation, and whereas deprivation treatment increased heat-induced seizure susceptibility in control flies, it unexpectedly reduced seizure activity in GEFS+ mutants. Our study has revealed the sleep architecture of a Drosophila VGSC mutant that harbors a human GEFS+ mutation, and provided unique insight into the relationship between sleep and epilepsy.

Abstract
The hospital-based prospective study was conducted in Combined Military Hospital, Kharian, Pakistan, from January 2012 to December 2013, to determine the demographic, clinical and aetiological profile of paediatric patients admitted with febrile seizures. Patients clinically diagnosed as a case of febrile seizure were included in study. Patient's information was collected using a predesigned proforma. Out of total enrolled 100 children, 68(68%) were male and 32(32%) female. Mean age of the sample was22.58±12.50 months. Mean time interval between onset of fever and occurrence of seizures was17.68±12.09 hours. Overall, 78(78%) patients had simple seizures. Only 30(30%) patients had positive family history and 35(35%) had recurrence of seizures during the same episode of illness. Acute respiratory infection was the commonest cause for FS in 72(72%).Besides, 64(64%) patients were malnourished, 77(77%) had anaemia and 51(51%) had raised total leukocyte count.

Abstract
The causes of febrile convulsions are usually benign. Such convulsions are common in children and their long-term consequences are rare. However, other causes of seizures, such as intracranial infections, must be excluded before diagnosis, especially in infants and younger children. Diagnosis is based mainly on history taking, and further investigations into the condition are not generally needed in fully immunised children presenting with simple febrile convulsions. Treatment involves symptom control and treating the cause of the fever. Nevertheless, febrile convulsions in children can be distressing for parents, who should be supported and kept informed by experienced emergency department (ED) nurses. This article discusses the aetiology, clinical presentation, diagnosis and management of children with febrile convulsion, and best practice for care in EDs. It also includes a reflective case study to highlight the challenges faced by healthcare professionals who manage children who present with febrile convulsion.

Abstract
INTRODUCTION Febrile seizures are one of the most frequent reasons why patients visit the healthcare specialist. Up until now, patients with complex febrile seizures (CFS) have been hospitalised, bearing in mind the higher percentages of epilepsy and acute complications that were classically reported. Today there are studies that back the idea of being less invasive in the management of these patients. AIMS. To describe the characteristics of patients hospitalised due to CFS and to propose a new protocol to be followed in dealing with such cases. PATIENTS AND METHODS The medical records of patients hospitalised because of CFS (January 2010-December 2013) were analysed retrospectively. Epidemiological and clinical data are presented, together with information from complementary tests and about development. RESULTS CFS account for 4.2% of all neuropaediatric cases of admittance to hospital in (67 patients). Mean age at the time of the event: 25 months. A pathological family history existed in 47% of cases, and 31% had a previous personal history of febrile seizures. The CFS lasted less than five minutes in 54% of patients; there were also recurrences, most of them with a total of two crises and during the first day (CFS due to recurrence are the most frequent). None of the complementary tests that were carried out were of any use as a diagnostic aid during the acute phase. During their follow-up, five patients presented complications. Patients with a family history of febrile seizures presented a higher risk of epilepsy or recurrence (p = 0.02), with no significant differences as regards age, number of seizures, febrile interval, epileptic status or type of CFS. CONCLUSIONS The CFS are not associated with greater acute complications, and the complementary examinations do not allow high-risk patients to be distinguished at an early stage. Hospitalising them could be avoided in the absence of other clinical signs and symptoms, and thus be limited to selected cases.
