Aspectos electroclínicos de la epilepsia temporal mesial / Neuropsychological risk in temporal lobe epilepsy

Introducción: La epilepsia del lóbulo temporal mesial se considera la más frecuente de las epilepsias focales, con signos y síntomas característicos que ayudan a definir su diagnóstico. Contenidos: Dentro de su historia natural, las crisis pueden iniciar en los primeros años de vida, usualmente como episodios febriles con un periodo de remisión, para reaparecer en la adolescencia o en el adulto joven. La presentación electroencefalográfica tiene un patrón característico, con aparición de puntas y ondas agudas interictales en la región temporal anterior, por lo general unilaterales, y con actividad ictal generalmente theta en la misma localización. La causa más frecuente es la esclerosis del hipocampo. El tratamiento con medicamentos anticrisis puede controlar la epilepsia, aunque algunos casos pueden evolucionar a la farmacorresistencia, en la cual la cirugía de epilepsia está indicada, y tiene buenos resultados. Conclusiones: Esta revisión se centra en la descripción de las características electroclínicas de la epilepsia temporal mesial, para hacer un diagnóstico temprano e iniciar un tratamiento adecuado, a efectos de lograr un mejor pronóstico y una mejor calidad de vida para los pacientes con epilepsia y sus familiares.

Introduction: Mesial temporal lobe epilepsy is considered the most common of the focal epilepsies, with characteristic signs and symptoms that help define its diagnosis. Contents: In the natural history of the disease, seizures can begin in the first years of life, usually as febrile seizures with a period of remission, to reappear in adolescence or in the young adult. The electroencephalographic presentation has a characteristic pattern with the appearance of interictal sharp waves and spikes in the anterior temporal region, usually unilateral, and with generally theta ictal activity in the same location. The most common cause is hippocampal sclerosis. Treatment with antiseizure medication can control epilepsy. However, in some cases evolution of drug resistance can occur, leading to epilepsy surgery as the most appropriate treatment, based on its good results. Conclusions: This review focuses on the description of the electroclinical characteristics of temporal mesial epilepsy, in order to make an early diagnosis and adequate treatment, thus providing a better prognosis and quality of life for patients with epilepsy and their families.

Clinical features of children with febrile seizures caused by Omicron variant infection / 中国当代儿科杂志

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.

Epidemiology of Dengue in patients with febrile syndrome at Saint Camille Hospital, Ouagadougou, Burkina Faso from 2020 to 2

: Dengue is still a public health problem in tropical countries. This disease, which had almost disappeared in some areas of the world, has become re-emergent in certain parts of the world including Africa.The aim of this study is to determine the seroprevalence and evolution of Dengue virus (DENV) infection from 2020 to 2021 at the Hospital Saint Camille de Ouagadougou (HOSCO), Burkina Faso. Methodology: This was a descriptive analytical study of patients seen in general practice with febrile syndrome referred for serological diagnosis of Dengue at the HOSCO laboratory over a period of 2 years (January 1, 2020 ­ December 31, 2021). The "Dengue Duo (AgNS1/IgM/IgG)" kit from SD Bioline was used for the rapid diagnosis through the detection of NS1 antigen and IgM/IgG antibodies in plasma. Data were analysed with SPSS version 20.0 software. Association between demographic data and prevalence of DENV infection was determined by Chisquare test and odds ratio (with 95% confidence interval). P value less than 0.05 was considered statistical significance. Results: A total of 2957 patients aged 0-94 years were referred for serological diagnosis of DENV infection at the HOSCO laboratory over the period 2020-2021, comprising 56.3% females and 43.7% males. The overall prevalence of acute DENV infection (NS1Ag positive) was 5.4% (159/2957), with 2.4% (41/1700) in 2020 and 9.4% (118/1257) in 2021 (OR=4.192, 95% CI=2.915-6.028, p<0.0001). The prevalence of acute DENV infection of 7.0% (91/1292) in the males was significantly higher than 4.1% (68/1665) in the females (OR=1.779, 95% CI=1.288-2.458, p=0.0005), and also significantly higher in age groups 20-29 years (7.6%), 10-19 years (6.9%) and 40-49 years (5.8%) than other age groups (X 2=14.928, p=0.0107). The overall prevalence of DENV IgM and IgG antibodies was 3.2% and 37.3% respectively. The prevalence of DENV IgG antibodies was significantly higher in males (44.0%) than females (32.1%) (OR=1.667, 95%CI=1.434-1.938, p<0.0001) and in age groups 30-39 (43.4%), 40-49 (44.0%) and >50 years (49.3%) than other age groups (X2=121.0, p<0.0001), indicating that past exposure to DENV infection is higher among males and older age groups. The peak of DENV infection was between October and November with 84.3% (134/159) of NS1Ag positivity occurring during this period. Conclusion: The present study reports a high prevalence of acute Dengue virus infection in patients from October to November. To eradicate Dengue which has become a tropical silent epidemic, interventions such as vector control, availability of and accessibility to diagnostic tests, and good therapeutic management are of great importance

Folate levels in children with sickle cell anemia on folic acid supplementation in steady state and crises at a tertiary hospital in Enugu, Nigeria a prospective, comparative study

Folic acid supplementation is an integral aspect of the management of children with sickle cell anaemia (SCA) especially in Africa. In spite of this, there have been concerns about lower folate levels, especially during crisis. AimTo determine red cell folate levels of children with sickle cell anaemia in steady state and during crisis and compare with those with haemoglobin AA genotype. Method This study was prospective, hospital based, and comparative. Fifty children with sickle cell anaemia were recruited during crises and followed up until they met the criteria for attaining steady state. The controls were fifty children matched with those with SCA for age and gender and had haemoglobin AA genotype. Red cell folate estimation was done with the Electrochemiluminescence Immunoassay (ECLIA) method using the automated Roche Cobas e411 equipment. Results The median (IQR) red cell folate level in children during sickle cell crisis was 265.95 (134.50) ng/ml, which was significantly lower than the median (IQR) of 376.30 (206.85) ng/ml obtained during steady state. Most children with SCA (41 out of 50) had significantly higher folate levels during steady state (T=1081, Z-score= -4.660, p < 0.001). Median level of red cell folate was lower during anaemic crisis compared to vaso-occlusive crisis, though not significantly so (N(50), U = 214.00, Z-score= -1.077, p = 0.305). The median red cell folate level of normal controls was 343.55 (92.90) ng/ml, which was significantly lower than the 376.30 (206.85) ng/ml obtained during steady state (N(50), U= 209.00, Z-score= -7.177, p <0.001). Conclusion Median red cell folate levels of the study participants were within normal limits, though most children with SCA had significantly higher levels during steady state compared to crisis. Normal controls had significantly lower red cell folate levels than the children with SCA during steady state

BPAN manifesting with febrile seizures and language delay: a case report from Brazil

Neurodegeneration with brain iron accumulation (NBIA) is a complex group of hereditary progressive neurodegenerative diseases characterized by deposition of iron in the basal ganglia. Twelve genetic forms of this disorder have been identified in previous studies. Though they have different inheritance mechanisms all are usually associated with abnormal brain MRI findings. One of NBIA types is an X-linked disorder known as Beta-propeller Protein Associated Neurodegeneration (BPAN). Herein we describe the case of a 4-year-old girl with 2 episodes of febrile seizures, a brain MRI showing nonspecific hyperintense signal in the dentate nucleus area, and delays in language and communication development. Her diagnosis was made based on a genetic evaluation where exome sequencing revealed a mutation in the position chrX:48.933.022 region of the WDR45 gene. The literature describes different clinical presentations for BPAN, each with a different prognosis, suggesting a wide range of possible symptoms of BPAN, including mild cognitive delay and even epileptic encephalopathy (EE).

Early identification and diagnosis of epilepsy related to fever sensitivity / 中国当代儿科杂志

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

Analysis of clinical phenotype and SCN1A gene variant in a pedigree affected with genetic epilepsy with febrile seizures / 中华医学遗传学杂志

OBJECTIVE@#To explore the genetic basis for a Chinese pedigree affected with genetic epilepsy with febrile seizures plus (GEFS+).@*METHODS@#Clinical data of the proband and his family members were collected. Following extraction of genomic DNA, the proband was subjected to high-throughput sequencing. Candidate variant was verified by Sanger sequencing of the proband and other family members.@*RESULTS@#The pedigree, including 6 patients with febrile seizures from 3 generations, was diagnosed with typical GEFS+. Among them, 2 had febrile seizures (FS), 1 had febrile seizures plus (FS+), and 3 had febrile seizures with focal seizures. High-throughput sequencing revealed that the proband has carried a heterozygous missense variant of c.4522T>A (p.Tyr1508Asn) of the SCN1A gene. Sanger sequencing confirmed that other five patients and one normal member from the pedigree have also carried the same variant, which yielded a penetrance of 85.7%.@*CONCLUSION@#The c.4522T>A (p.Tyr1508Asn) of the SCN1A gene probably underlay the disease in this pedigree. The pattern of inheritance was consistent with autosomal dominant inheritance with incomplete penetrance. Above finding has enriched the variant spectrum of the SCN1A gene.

A case of 16p13.11 microdeletion syndrome with febrile convulsion as the main manifestation / 中华医学遗传学杂志

OBJECTIVE@#To explore the genetic basis for a girl with febrile convulsion as the main manifestation.@*METHODS@#The child was subjected to whole exome sequencing (WES) and copy number variation sequencing(CNV-seq). Fluorescence quantitative PCR was carried out to validate the microdeletion in her family.@*RESULTS@#The 7-year-old girl was diagnosed with febrile convulsion (complex type) for having fever for 3 days, mild cough and low thermal convulsion once. Her father, mother and aunt also had a history of febrile convulsion. A heterozygous deletion with a size of approximately 1.5 Mb was detected in the 16p13.11 region by WES and CNV-seq. The deletion has derived from her father and was confirmed by fluorescence quantitative PCR.@*CONCLUSION@#16p13.11 microdeletion syndrome has significant clinical heterogeneity. Different from those with epilepsy, mental retardation, autism, multiple malformations, carriers of 16p13.11 deletion may only manifest with febrile convulsion. Deletion of certain gene(s) from the region may be related to febrile convulsion and underlay the symptom of this child.

OBJECTIVE@#To study the change and significance of hippocampal volume (HCV) in children with recurrent febrile seizures.@*METHODS@#A retrospective analysis was performed on the medical data and examination results of 34 children with recurrent febrile seizures who underwent two magnetic resonance plain scans of the head and the hippocampus from January 1, 2013 to September 30, 2019. According to the follow-up time, they were divided into the first follow-up group and the second follow-up group. According to prognosis, they were divided into a febrile seizure group, a non-febrile group and an epilepsy group. The change in HCV was analyzed and compared.@*RESULTS@#Total HCV was positively correlated with age (@*CONCLUSIONS@#HCV gradually increases with age in children with recurrent febrile seizures. Persistent seizures may damage the development of the hippocampus.

Vigilancia activa de convulsiones febriles vinculadas a vacuna pentavalente en un hospital centinela en Uruguay / Active surveillance of febrile seizures associated to DPT vaccines in a sentinel hospital in Uruguay

Resumen Introducción: Las convulsiones febriles son eventos supuestamente atribuidos a la vacunación e inmunización (ESAVI) frecuentemente asociados a vacuna difteria - tétanos- pertussis a células completas. Objetivo: Analizar la asociación de convulsiones febriles con la administración de la vacuna pentavalente en niños bajo 2 años de edad asistidos en el Centro Hospitalario Pereira Rossell durante el año 2014. Material y Métodos: Estudio de series de casos auto-controlados. Se incluyeron niños procedentes de Montevideo con 2 a 24 meses de edad con diagnóstico de convulsión febril. Se estimó el riesgo relativo (RR) de los períodos de riesgo (0 a 3 días) y de lavado (4a 14 días), en comparación con el período de no riesgo (más de 14 días). Resultados: Se registraron 135 convulsiones febriles, que ocurrieron en 114 niños; 16 niños presentaron dos o más episodios. El total de eventos ocurridos en el período de riesgo fueron 7 (5,2%) y 8 (5,9%) en el período de lavado. El período de riesgo mostró un RR significativo de 4,14 (IC 95%: 1,73; 8,36). Conclusiones: Este trabajo permitió establecer una línea de base nacional sobre el riesgo de convulsiones febriles asociadas con la vacunación pentavalente al utilizar por primera vez en el país una metodología específica para tal fin.

Background: Febrile seizures are VAERS often associated with whole-cells Diphtheria-Pertussis-Tetanus vaccines. Aim: To analyze the association of febrile seizures with the administration of pentavalent vaccine in children under two-years-old assisted in the Centro Hospitalario Pereira Rossell (CHPR), in Montevideo during 2014. Methods: Self-controlled case series study. We included children from Montevideo from two to 24-month-old at the time of admission, with diagnosis of febrile seizure at the time of discharge. We estimated the relative risk in three time periods: 0 to 3 days (risk period), 4 to 14 days (wash-out) and more than 14 days after vaccination (no-risk). Results: We recorded 135 febrile seizures in 114 children, 16 of whom presented two or more events. The total number of events was 7 (5.2%) in risk periods and 8 (5.9%) in wash-out periods. The risk period showed a significantly increased risk (RR = 4.14, CI 95% = [1.73; 8.36]). Conclusions: This work allowed us to establish a national base line for the risk of febrile seizures associated with pentavalent vaccination, by using for the first time in the country a methodology specifically designed for this goal.

Estado epiléptico refractario en UCIP. Experiencia en un hospital de la Provincia de Buenos Aires / Refractory status epilepticus in the PICU. Experience at a hospital in the Province of Buenos Aires

Introducción: El estado epiléptico (EE) es la emergencia neurológica más frecuente en pediatría. Los pacientes que no responden al tratamiento estándar con dosis adecuadas de benzodiacepinas seguido de una droga antiepiléptica aceptable son definidos como Estado epiléptico Refractario (ER). Objetivo: caracterizar la población de niños con EE que ingresan a UCIP y determinar qué factores son predictores de refractariedad en esta población. Métodos: Estudio de casos y controles, retrospectivo. Población: niños con EE internados en UCIP desde Febrero 2015 a Febrero 2017. Casos: Estado epiléptico Refractario (ER). Controles: Estado epiléptico No Refractario (ENR). Se calculó el Odds Ratio (OR) individual para las distintas variables en Med Calc. Resultados: Se internaron 35 pacientes de los cuales 12 fueron casos y 23 controles. Hubo fiebre en 77% de los pacientes. En el total de niños estudiados hubo 11% con antecedente de convulsión febril, 11% con antecedente de epilepsia y 9% con antecedente de malformación del SNC. Los niños con antecedente de convulsión febril tuvieron 2,5 veces mayor riesgo de ER (OR: 2,58; IC 95%: 1,17-5,68). Los niños con EE que tenían antecedentes de enfermedad neurológica previa presentaron riesgo de ER 2,6 veces mayor que el grupo control (OR 2,60; IC 95%: 1,24-5,42). Discusión: Dado el aumento en la mortalidad de los pacientes con ER sería importante disponer de más herramientas para predecir este desenlace e iniciar tratamiento oportuno. Resultaría útil entrenar a los padres de niños con antecedente de convulsión febril en la aplicación de medicación antiepiléptica prehospitalaria, esto podría prevenir la farmacorresistencia, el daño neurológico y las complicaciones que acarrea el ingreso a UCIP.

Introduction: Status epilepticus (SE) is the most common neurologic emergency in children. Patients that do not respond to standard treatment with adequate doses of benzodiazepines followed by an acceptable antiepileptic drug are defined as having refractory status epilepticus (RSE). Objective: To characterize the population of children with SE admitted to the PICU and to determine predictive factors for refractoriness in this population. Methods: A retrospective case-control study was conducted. Population: Children with SE admitted to the PICU between February 2015 and February 2017. Cases: Refractory status pilepticus (RSE). Controls: Non-refractory status epilepticus (NRSE). Individual Odds Ratio (OR) was calculated for different variables using Med Calc. Results: 35 patients were admitted of whom 12 were cases and 23 controls. Overall, 77% of the patients had fever. Of all the children, 11% had a history of febrile seizures, 11% had history of epilepsy and 9% had a CNS malformation. Children with a history of febrile seizures had a 2.5-fold higher risk of developing RSE (OR: 2.58; 95% CI: 1.17-5.68). Children with SE that had a history of neurologic disease had a 2.6-fold higher risk of developing RSE than controls (OR 2.60; 95% CI: 1.24-5.42). Discussion: Given the increased mortality in children with RSE, availability of tools to predict this outcome in order to initiate early treatment is important. It would be useful to train the parents of children with a history of febrile seizures in the prehospital administration of antiepileptic drugs as this may prevent pharmaco-resistance, neurologic damage, and complication related to PICU admission (AU)

Heat-related skin disease

Skin disease can be caused by high temperature, and it is related to the temperature regulation mechanism of human body, adaptation reaction to temperature change, and health problems due to the recent problematic climate change. In hyperthermia, hot and dry skin is typical manifestation, and sometimes the skin color turns red. On the other hand, the skin color can become pale in severe febrile convulsion. Burn is a skin damage caused by heat, and not only the skin but also the underlying tissues can be destroyed in severe case. It is important to determine the degree and extent of the burn to treat adequately. In the case of severe burns, systemic treatment and prevention of infection or shock should be needed. Miliaria, also called “sweat rash,” occurs when the sweat is accumulated as the sweat gland is closed and sweat cannot be secreted to the surface of the skin. The basis of treating miliaria is to keep the patient in a cool environment. Erythema ab igne is defined as a network of hyperpigmentation that occurs after prolonged exposure to heat that is not enough to cause burn. It may disappear when exposure to heat is interrupted, but it may remain permanently. The extent and mechanism of heat-induced skin disease very diverse and it should be carefully assessed for the severity of each disease, the treatment method and prognosis.

Elevated Serum Uric Acid in Benign Convulsions with Mild Gastroenteritis in Children

BACKGROUND AND PURPOSE: To identify whether serum uric acid levels are significantly higher in patients with benign convulsion associated with mild gastroenteritis (CwG) than in patients with acute gastroenteritis. METHODS: This retrospective study compared the serum levels of uric acid between CwG, acute gastroenteritis, and febrile seizure after correcting for the varying degree of mild dehydration using serum HCO3⁻ levels. We also compared the serum uric acid levels between patients with CwG and febrile seizures in order to exclude the effect of seizures on uric acid. RESULTS: This study included 154 CwG patients (age range 0.73–3.19 years), 2,938 patients with acute gastroenteritis, and 154 patients with febrile seizure. The serum uric acid level was significantly higher in CwG patients than in patients with acute gastroenteritis [9.79±2.16 mg/dL vs. 6.04±2.3 mg/dL (mean±SD), p<0.001]. This difference was also significant after correcting for dehydration. The serum uric acid level was significantly higher in CwG patients than in dehydration-corrected acute gastroenteritis patients (9.79±2.16 mg/dL vs. 6.67±2.48 mg/dL, p<0.001). The serum uric acid level was not elevated in patients with febrile seizure. CONCLUSIONS: We have confirmed that serum uric acid is elevated in CwG patients even after correcting for their dehydration status, and that this was not a postictal phenomenon. Highly elevated serum uric acid in CwG could be a useful clinical indicator of CwG in patients with acute gastroenteritis.

Association Analysis of Interleukin-1β, Interleukin-6, and HMGB1 Variants with Postictal Serum Cytokine Levels in Children with Febrile Seizure and Generalized Epilepsy with Febrile Seizure Plus

BACKGROUND AND PURPOSE: Febrile seizure (FS) is a unique type of seizure that only occurs during childhood. Genelized epilepsy with febrile seizure plus (GEFS+) is a familial epilepsy syndrome associated with FS and afebrile seizure (AFS). Both seizure types are related to fever, but whether genetic susceptibility to inflammation is implicated in them is still unclear. To analyze the associations between postictal serum cytokine levels and genetic variants in the cytokine genes interleukin (IL)-1β, IL-6, and high mobility group box-1 (HMGB1) in FS and GEFS+. METHODS: Genotyping was performed in 208 subjects (57 patients with FS, 43 patients with GEFS+, and 108 controls) with the SNaPshot assay for IL-1β-31 (rs1143627), IL-1β-511 (rs16944), IL-6-572 (rs1800796), and HMGB1 3814 (rs2249825). Serum IL-1β, IL-6, and HMGB1 levels were analyzed within 2 hours after seizure attacks using the ELISA in only 68 patients (38 FS, 10 GEFS+, and 20 controls). The allele distribution, genotype distribution, and correlations with serum cytokine levels were analyzed. RESULTS: Near-complete linkage disequilibrium exists between IL-1β-31 and IL-1β-511 variants. CT genotypes of these variants were associated with significantly higher postictal serum IL-1β levels than were CC+TT genotypes in FS (both p<0.05). CT genotypes of IL-1β-31 and IL-1β-511 variants were more strongly associated with FS than were CC+TT genotypes (odds ratio=1.691 and 1.731, respectively). For GEFS+, serum IL-1β levels after AFS for CT genotypes of IL-1β-31 and IL-1β-511 were also higher than for CC+TT genotypes. No significant associations were found for IL-6 and HMGB1. CONCLUSIONS: Genetic variants located in IL-1β-31 and IL-1β-511 promotor regions are correlated with higher postictal IL-1β levels in FS. These results suggest that IL-1 gene cluster variants in IL-1β-31 and IL-1β-511 are a host genetic factor for provoking FS in Korean children.

Correlation of serum S100B levels with brain magnetic resonance imaging abnormalities in children with status epilepticus / 소아과

PURPOSE: To evaluate the association between elevated S100B levels with brain tissue damage seen in abnormalities of head magnetic resonance imaging (MRI; diffusion tensor imaging [DTI] sequence) in patients with status epilepticus (SE). METHODS: An analytical observational study was conducted in children hospitalized at Dr Soetomo Hospital, Surabaya, from July to December 2016. The patients were divided into 2 groups: SE included all children with a history of SE; control included all children with febrile seizure. Blood samples of patients were drawn within 24 hours after admission. SE patients also underwent cranial MRI with additional DTI sequencing. The Mann-Whitney test and Spearman test were used for statistical analysis. RESULTS: Fifty-three patients were enrolled the study. In the 24 children with SE who met the inclusion criteria, serum S100B and cranial MRI findings were assessed. Twenty-two children admitted with febrile seizures became the control group. Most patients were male (66.7%); the mean age was 35.8 months (standard deviation, 31.09). Mean S100B values of the SE group (3.430±0.141 μg/L) and the control group (2.998±0.572 μg/L) were significantly different (P<0.05). A significant difference was noted among each level of encephalopathy based on the cranial MRI results with serum S100B levels and the correlation was strongly positive with a coefficient value of 0.758 (P<0.001). CONCLUSION: In SE patients, there is an increase of serum S100B levels within 24 hours after seizure, which has a strong positive correlation with brain damage seen in head MRI and DTI.

Respiratory syncytial virus-associated seizures in Korean children, 2011–2016 / 소아과

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±16.6 months) 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.
