RESUMEN

Abstract Objective: To assess the performance of cerebrospinal fluid (CSF) lactate as a biomarker to differentiate bacterial meningitis from viral meningitis in children, and to define an optimal CSF lactate concentration that can be called significant for the differentiation. Methods: Children with clinical findings compatible with meningitis were studied. CSF lactate and other conventional CSF parameters were recorded. Results: At a cut-off value of 3 mmol/L, CSF lactate had a sensitivity of 0.90, specificity of 1.0, positive predictive value of 1.0, and negative predictive value of 0.963, with an accuracy of 0.972. The positive and negative likelihood ratios were 23.6 and 0.1, respectively. When comparing between bacterial and viral meningitis, the area under the curve for CSF lactate was 0.979. Conclusions: The authors concluded that CSF lactate has high sensitivity and specificity in differentiating bacterial from viral meningitis. While at a cut-off value of 3 mmol/L, CSF lactate has high diagnostic accuracy for bacterial meningitis, mean levels in viral meningitis remain essentially below 2 mmol/L.


Resumo Objetivo: Estudar o desempenho do lactato no líquido cefalorraquidiano como biomarcador para diferenciar a meningite bacteriana da meningite viral em crianças, e definir uma concentração de lactato ótima no líquido cefalorraquidiano que possa ser significativa para a diferenciação. Métodos: Foram estudadas crianças com achados clínicos compatíveis com meningite. O nível de lactato no líquido cefalorraquidiano e outros parâmetros convencionais do líquido cefalorraquidiano foram registrados. Resultados: Em um valor de corte de 3 mmol/L, o lactato no líquido cefalorraquidiano apresentou uma sensibilidade de 0,90, especificidade de 1,0, valor preditivo positivo de 1,0, valor preditivo negativo de 0,963, com uma precisão de 0,972. Os índices de probabilidade positivo e negativo foram 23,6 e 0,1, respectivamente. Para comparação entre a meningite bacteriana e viral, a área abaixo da curva do lactato no líquido cefalorraquidiano foi 0,979. Conclusões: Concluímos que o lactato no líquido cefalorraquidiano possui alta sensibilidade e especificidade na diferenciação da meningite bacteriana da meningite viral. Embora em um valor de corte de 3 mmol/L o lactato no líquido cefalorraquidiano possua alta precisão de diagnóstico da meningite bacteriana, os níveis médios na meningite viral permanecem basicamente abaixo de 2 mmol/L.

RESUMEN

The management of newborns with esophageal atresia [EA] with or without tracheoesophageal fistula [TEF] has evolved considerably over the years. Currently an overall survival of 85% to 90% has been reported from developed countries. In developing Countries, several factors contribute to higher mortality rates. We describe our experience with 94 consecutive cases of EA with or without TEF. We retrospectively studied 94 patients with EA with or without TEF treated at our hospital over a period of 15 years. Medical records were reviewed for age at diagnosis, sex, birth weight, associated anomalies, aspiration pneumonia, method of diagnosis, treatment, postoperative complications and outcome. Ninety-four newborns [55 males and 39 females] with EA/TEF were treated at our hospital. Their mean birth weight was 22 kg [700 g to 3800 g]. Age at diagnosis ranged from birth to 7 day. At the time of admission 37 [39.4%] had aspiration pneumonia. Associated anomalies were seen in 46[49%] patients. Thirteen patients had major associated anomalies that contributed to mortality Postoperative complications were similar to those from developed countries but overall operative mortality [30.8%] was high. The overall mortality was high but excluding major congenital malformations, sepsis was the most frequent cause of death. Factors contributing to mortality included prematurity, delay in diagnosis with an increased incidence of aspiration pneumonia and a shortage of qualified nurses. To improve overall outcome, factors contributing to sepsis should be evaluated and efforts should be made to overcome them
