Simple and complex febrile seizures: is there such a difference? Management and complications in an emergency department.

OBJECTIVE: We aimed to analyse the prevalence, characteristics, and management of simple and complex febrile seizures. The secondary objective was to compare the risk of underlying organic lesion and epilepsy in both types of seizures, with a particular focus on the different subtypes defining a complex febrile seizure. MATERIAL AND METHODS: We performed a retrospective cohort study including patients aged 0--16 years who were treated for febrile seizures in the paediatric emergency department of a tertiary hospital over a period of 5 years. Epidemiological and clinical variables were collected. Patients were followed up for at least 2 years to confirm the final diagnosis. RESULTS: We identified 654 patients with febrile seizures, with a prevalence of 0.20% (95% CI, 0.18-0.22); 537 (82%) had simple febrile seizures and 117 (18%) had complex febrile seizures. The clinical and epidemiological characteristics of both types were similar. Significantly more complementary tests were requested for complex febrile seizures: blood tests (71.8% vs 24.2% for simple febrile seizures), urine analysis (10.3% vs 2.4%), lumbar puncture (14.5% vs 1.5%), and CT (7.7% vs 0%). Similarly, admission was indicated more frequently (41.0% vs 6.1%). Underlying organic lesions (central nervous system infection, metabolic disease, tumour/intracranial space-occupying lesion, intoxication) were diagnosed in only 11 patients, 5 of whom had complex forms (4.3%; 95% CI, 0.6-7.9). Risk factors for developing epilepsy, identified in the multivariate analysis, were complex forms with recurrent seizures in a single attack (odds ratio [OR]: 4.94; 95% CI, 1.29-18.95), history of seizures (OR: 17.97; 95% CI, 2.26--143.10), and seizures presenting at atypical ages (OR: 11.69; 95% CI, 1.99-68.61). CONCLUSIONS: The systematic indication of complementary tests or hospital admission of patients with complex febrile seizures is unnecessary. The risk of epilepsy in patients with complex forms gives rise to the need for follow-up in paediatric neurology departments.

Convulsiones febriles simples y complejas, ¿son tan diferentes? Manejo y complicaciones en urgencias / Simple and complex febrile seizures: is there such a difference? Management and complications in an emergency department

Objetivo: Analizar la prevalencia, características y manejo de las convulsiones febriles simples y complejas. Secundariamente, comparar el riesgo de lesión orgánica subyacente y epilepsia entre ambos tipos de crisis y particularmente de cada subtipo que define una convulsión febril compleja. Material y método: Estudio de cohortes retrospectivo que incluye pacientes de 0-16 años que consultan por convulsión febril en urgencias pediátricas de un hospital terciario durante 5 años. Se recogen variables epidemiológicas y clínicas. Se realiza un seguimiento posterior mínimo de 2 años para confirmar el diagnóstico final. Resultados: Se incluyeron 654 convulsiones febriles, con una prevalencia del 0,20% (IC 95%: 0,18-0,22%); 537 fueron simples (82%) y 117 complejas (18%). Las características clínico-epidemiológicas de ambos tipos fueron similares. En las formas complejas se solicitaron significativamente más pruebas complementarias en forma de analíticas (71,8% vs. 24,2%), tóxicos (10,3% vs. 2,4%), punción lumbar (14,5% vs. 1,5%) y TAC (7,7% vs. 0%). Igualmente se indicó ingreso con mayor frecuencia (41,0% vs. 6,1%). No se diagnosticó ninguna lesión orgánica subyacente (infección del sistema nervioso central, enfermedad metabólica, tumor/lesión intracraneal ocupante de espacio, intoxicación) excepto 11 casos de epilepsia, 5 de ellas en las formas complejas (4,3%; IC 95%: 0,6-7,9%). En el análisis multivariable presentaron mayor riesgo de desarrollar epilepsia las formas complejas por ser recurrentes en el mismo proceso febril (odds ratio [OR]: 4,94; IC 95%: 1,29-18,95), aquellos con antecedentes de crisis previas (OR: 17,97; IC 95%: 2,26-143,10) y las manifestadas a edades atípicas (OR: 11,69; IC 95%: 1,99-68,61). Conclusiones: No está justificada la indicación sistemática de pruebas complementarias o ingreso en las convulsiones febriles complejas. El riesgo de epilepsia en las formas complejas hace necesario el seguimiento en neuropediatría. (AU)

Intoxicación por fenitoína. Reacción cruzada con barbitúricos / Phenytoin intoxication. Cross-reaction with barbiturates

Las intoxicaciones suponen un motivo frecuente de consulta en Pediatría. El cribado toxicológico en orina es una herramienta de diagnóstico rápido y bajo coste, pero debemos tener precaución en su interpretación, ya que existen reacciones cruzadas con otros fármacos de estructura química similar. Se describe el caso clínico de un paciente de 11 años con afectación neurológica y resultados positivos para barbitúricos en orina. La confirmación de niveles elevados de fenitoína en sangre permite confirmar el diagnóstico y la reactividad cruzada de los resultados en orina

Intoxications are a common reason for consultation in Pediatrics. Urine toxicology screening is a rapid and low-cost tool, but these results have to be interpreted with caution due to cross reactions with other drugs with similar chemical structure. We describe the clinical case of a 11 years old patient with neurological involvement and positive results for barbiturates in urine. Confirmation of high levels of phenytoin in blood guaranteed the diagnosis and cross-reaction results in urine

Presencia de anticuerpos antifosfolípidos en niños con fiebre y petequias / Presence of antiphospholipid antibodies in children with fever and petechiae

Introducción: La presencia de un tiempo de cefalina (APTT) alargado en niños con fiebre y petequias es un hallazgo descrito en la bibliografía. La causa de esta alteración se desconoce, pero se postula que puede deberse a la formación de anticuerpos antifosfolípidos (Ac AFL). El objetivo de este estudio es determinar si el alargamiento del APTT se asocia con la formación Ac AFL. Pacientes y métodos: Estudio observacional, prospectivo, de casos y controles, realizado en niños que consultaron por fiebre y petequias en el servicio de urgencias de un hospital de tercer nivel durante un periodo de 13 meses. Se recogieron variables epidemiológicas, clínicas y analíticas. Se describieron las características de los grupos con APTT alargado y normal, y se comparó la asociación entre las concentraciones de los diferentes anticuerpos y el APTT. Resultados: Se incluyeron 36 pacientes, 12 casos y 24 controles. No se encontraron diferencias significativas respecto a la positividad de Ac AFL entre los casos y los controles (odds ratio [OR]= 1,67; intervalo de confianza [IC] del 95%: 0,31-9,04). No se observó ninguna asociación entre los diferentes tipos de anticuerpos y el APTT, cuyos coeficientes de regresión fueron de 0,04 seg (IC del 95%: -0,31 a 0,40) para anticardiolipina IgG, de 1,11 seg (IC del 95%: -1,24 a 3,46) para la IgM, y de -0,02 seg (IC del 95%: -0,35 a 0,31) y 0,64 seg (IC del 95%: -1,40 a 2,68) para antibeta 2 GPI, IgG e IgM, respectivamente. Conclusión: Ante los resultados de nuestro estudio, no podemos concluir que el alargamiento de APTT se relacione con la presencia de Ac AFL (AU)

Introduction: The presence of a longer time of cephalin (APTT) extended in children who come to emergency department with fever and petechiae is a result previously described in the literature. The cause of this alteration in coagulation is unknown, it is presumed that may be due to the formation of antiphospholipids antibodies. The aim of this study is to determine if the length of APTT is associated to the formation of antiphospholipids antibodies. Patients and methods: Observational, prospective case-control study in children who consulted for fever and petechiae in the emergency department of a tertiary hospital over a 13-month period epidemiological; clinical and laboratory variables were collected. The characteristics of groups with elongated and normal APTT were described and the association between concentrations of different antibodies and APTT were compared. Results: 36 patients, 12 cases and 24 controls, were included. No significant differences were found regarding the positivity of antiphospholipid antibodies between cases and controls (OR= 1.67; 95%CI: 0.31 to 9.04). No association was observed between the different types of antibodies and APTT, resulting regression coefficients in 0.04 s (95%CI: -0.31 to 0.40) for cardiolipin IgG, 1.11 s (95%CI: -1.24 to 3.46) for IgM and -0.02 s (95%CI: -0.35 to 0.31) and 0,64 s (95%CI: -1.40 to 2.68) for antibeta 2 GPI, IgG and IgM, respectively. Conclusion: Given the results of our study we can not conclude that the elongation of APTT is related with the presence of antiphospholipids antibodies (AU)

Utilidad de la procalcitonina en el diagnóstico precoz de apendicitis aguda / Usefulness of procalcitonin in early diagnosis of acute appendicitis

Introducción y objetivo: En los últimos años ha tratado de definirse la utilidad de los diferentes parámetros analíticos inflamatorios en el diagnóstico de la apendicitis aguda. El objetivo de este estudio es determinar el valor de la procalcitonina (PCT) en el diagnóstico precoz de esta entidad, comparándolo con los marcadores analíticos tradicionalmente solicitados en pacientes con dolor abdominal agudo (leucocitos/proteína C reactiva). Método: Estudio prospectivo analítico, durante el periodo comprendido entre julio y diciembre de 2011. Se incluyeron menores de 16 años con dolor abdominal y sospecha clínica de apendicitis. Se procedió al estudio de las variables analíticas (leucocitos, proteína C reactiva [PCR], PCT) y la elaboración de una curva ROC para los parámetros de laboratorio evaluados. Resultados: Se incluyeron 105 pacientes con una media de edad de 10,2 años (±3,3). El diagnóstico de apendicitis se confirmó por histología en el 39% (41/105), clasificándose el 42,5% como apendicitis perforada y el 11,5% como gangrenada. La cifra media de leucocitos fue significativamente mayor en el grupo con apendicitis (15,143/µL frente a 10,723/µL; p <0,001), al igual que el valor de la mediana de PCT (1,4 µg/L [rango: 0,7-6,1] frente a 0,6 µg/L [rango: 0,5-1,8]; p <0,05). El área bajo la curva ROC para la cifra de leucocitos fue de 0,76; los valores obtenidos para la PCR (0,63) y la PCT (0,6) fueron inferiores. La mayoría de los pacientes (94/105), así como los diagnosticados de apendicitis (31/41), mostraron valores de PCT normales. No obstante, el diagnóstico de apendicitis se confirmó en todos los que presentaron un aumento de la PCT, excepto en 2. Todas las apendicitis gangrenadas presentaron una elevación de la PCT. Conclusiones: La PCT no es un buen marcador precoz de apendicitis. No obstante, su elevación actúa como factor predictivo en el diagnóstico de apendicitis y su grado de evolución (AU)

Introduction and objective: Recent studies have tried to define the usefulness of different inflammatory laboratory parameters in the diagnosis of acute appendicitis. The objective of this study is to determine the value of procalcitonin (PCT) in the early diagnosis of this entity, compared with traditional laboratory markers in patients with acute abdominal pain (WBC/CRP). Methods: Prospective analytical study. Period: July to December 2011. Inclusion of children under 16 years with abdominal pain and clinical suspicion of appendicitis. Analytical analysis (leukocytes, CRP, PCT) and development of a ROC curve for laboratory parameters evaluated. Results: We included 105 patients with a mean age 10.2 years (± 3.3). The diagnosis of appendicitis was confirmed by histology in 39% (41/105), 42.5% of them were classified as perforated appendicitis and 11.5% as gangrenous. The average number of leukocytes was significantly higher in the group with appendicitis (15.143/μL vs 10.723/μL; p <0.001), like the median value of PCT (1.4 µg/L [0.7 to 6.1] vs 0.6 µg/L [0.5 to 1.8]; p <0.05). The area under the ROC curve for leukocyte count was 0.76; the values obtained for the PCR (0.63) and PCT (0.6) were lower. The majority of patients (94/105) and those diagnosed of appendicitis (31/41) showed normal PCT values. The diagnosis of appendicitis was confirmed in those with increased PCT, but 2. All patients with gangrenous appendicitis had elevation of PCT. Conclusions: PCT is not a good early marker of appendicitis. However, his elevation acts as a predictor for the diagnosis of appendicitis and its degree of evolution (AU)
