ABSTRACT
A meningite é a principal síndrome infecciosa que afeta o sistema nervoso central, e grande parte dos casos são ocasionados por infecções virais, principalmente por Enterovirus. O diagnóstico clínico para a verificação da etiologia da meningite ainda apresenta grandes desafios. O teste de Reação em Cadeia da Polimerase, leucócitos, hemácias, glicose, proteína e lactato no líquido cefalorraquidiano fornecem os primeiros indícios para o diagnóstico. No entanto, os valores de referência de alguns parâmetros podem sofrer alteraçõesOBJETIVO: Verificar parâmetros laboratoriais do líquido cefalorraquidiano em indivíduos com meningite por Enterovirus e, posteriormente, analisar suas relações por faixa etáriaMÉTODO: Foi realizado um estudo descritivo, com base nos dados do serviço de referência de coleta de líquido cefalorraquiano, localizado em São Paulo, Brasil. Totalizou-se em 202 indivíduos que apresentaram meningite por Enterovirus. Os dados foram analisados pelo teste de Shapiro-Wilk e Kruskal-Wallis (IC = 95%, p < 0,05) e representados pela mediana e percentil 25 e 75...
Meningitis is the leading infectious syndrome that affects the central nervous system, and most cases are caused by viral infections, mainly enterovirus. The clinical diagnosis for meningitis etiology still presents major challenges. The analysis of polymerase chain reaction (PCR), white blood cells, red blood cells, glucose, protein, and lactate in the cerebrospinal fluid (CSF) provides the first clues to the diagnosis. However, the reference values of some parameters can suffer changesOBJECTIVE: Analyze the laboratory parameters of CSF in patients with enterovirus meningitis, and then, theirrelationship by age groupMETHODS: A descriptive study was conducted based on data from a CSF reference service, located in São Paulo, Brazil, on 202 individuals who had enterovirus meningitis. Data was analysed by the Shapiro-Wilk and Kruskal-Wallis tests (CI = 95%, p < 0.05) and represented by the median and percentile 25 and 75, respectively...

La difícil interpretación de los hallazgos sugestivos de meningitis bacteriana y viral en el líquido cefalorraquídeo con frecuencia imposibilita su diferenciación. Por décadas, los investigadores han intentado crear escalas predictivas que permitan resolver tal disyuntiva. El objetivo del presente trabajo es determinar la validez y seguridad de una escala clínica predictiva para el diagnóstico de meningitis bacteriana en Pediatría. Realizamos un estudio retrospectivo, transversal, de evaluación de una prueba diagnóstica en una muestra de pacientes con edades entre 29 días y 12 años, egresados con diagnóstico de meningitis entre enero de 1992 y diciembre de 2006, del Deparatmento de Pediatría del Hospital "Dr. Jesús Yerena", ubicado en Caracas, Venezuela. aplicamos una escala clínica predictiva y calculamos su sensibilidad, especificidad, valores predictivos y razones de verosimilitud para el diagnóstico de meningitis bacteriana. La muestra estuvo conformada por 41 pacientes. Predomino el sexo masculino (n=29; 70,73 por ciento). El grupo etareo más afectado fue el de los lactantes menores (26=; 63,41 por ciento). Se identificaron 14 meningitis bacterianas y 27 asépticas. Mediante la escala clínica predictiva se clasificaron 31 meningitis como de alto riesgo de meningitis v¡bacteriana y 10 como de bajo riesgo. La sensibilidad y valor predictivo negativo fueron de 100 por ciento. La escala clínica predictiva resultó ser válida y segura para descartar meningitis bacteriana.
The overlapping of finding suggestive of bacterial or viral meningitis in cerebrospinal fluid makes it difficult to differentiate one of another. For decades, investigators have attempted to create clinical prediction scores to resolve such disjunctive. The objetive of this investigation was to determine the validity and safety of a clinical prediction score for the diagnosis of bacterial meningitis in childhood. We perfomed a retrospective, transversal, diagnosis test evaluation study of a sample of patients between 29 days to 12 years of age, dischanged from January 1992 to December 2006, with diagnosis of meningitis, from the Pediatrics Department of Dr. Jesús Yerena Hospital, in Caracas, Venezuela. The clinical prediction score was applied. We evaluated its validity and safety with the calculation of sensibility, specificity, predictive values and likelihood ratios for the diagnosis of bacterial meningitis. A total of 41 patients were included. Male gender was more common (n=29; 70,73%). The infant age group was predominant (n=26; 63,41%). We identified 14 bacterial meningitis and 27 aseptic meningitis. With the clinical predictin score, 31 meningitis were classified as high risk of bacterial meningitis and 10 as low risk. The sensibility and the negative value were 100%. The clinical prediction score applied resulted to be valid and safe for identifying patients without bacterial meningitis.

Kawasaki syndrome is an acute, sometimes fatal vasculitis of young children. The ethiology of the illness is unknown, but its clinical and epidemiologic features are most consistent with an infectious cause. We treated a 9-month-old infant with diagnosis of bacterial meningitis. He received wide spectrum antibiotics. He was clinically improved but in 8th day of admission he again developed pharyngitis, diarrhea and high grade fever. He has had raising of erythrocyte sedimentations rate [ESR] and thrombocytosis. According to these clinical manifestation with impression of atypical Kawasaki disease, treatment was started for him and after 24 hours his fever subsided and other clinical signs relieved. On the basis of this case report in the course of bacterial meningitis if the patient developed elevated ESR and fever, Kawasaki syndrome with the other complications of meningitis should be considered
