ABSTRACT
Se presenta el caso de un niño de 5 años sin antecedentes de enfermedad, que se internó en terapia intensiva por convulsiones tónico-clónicas focalizadas en la cara y en el hemicuerpo derecho, con documentación de temperatura axilar de 37,4°C. Se descartó la presencia de gérmenes comunes y la etiología viral a través de estudios de muestras de líquido cefalorraquídeo (LCR). Se sospechó la presencia de Mycoplasma pneumoniae por comprobarse inmunofluorescencia positiva en suero para anticuerpos de clase IgM. El diagnóstico se confirmó mediante la detección del ADN de dicho patógeno sobre la biopsia cerebral efectuada por el método de la reacción en cadena de la polimerasa (PCR) y una histología compatible con encefalomielitis aguda diseminada. El paciente recibió tratamiento con claritromicina y su evolución fue favorable. Al menos dentro de nuestros conocimientos, este es el primer caso en el que se detectó ADN de M. pneumoniae en una biopsia cerebral por el método de PCR.
We present here the case of a previously healthy 5 year-old boy hospitalized in an intensive care unit due to tonic-clonic seizures focused on the face and right side of the body, and axillary temperature of 37.4 °C. Common bacterial and viral etiology was ruled out through studies of cerebrospinal fluid (CSF) samples. Mycoplasma pneumoniae was suspected by a positive immunofluorescence serum test for IgM class antibodies. Finally, with a brain biopsy, M. pneumoniae was confirmed by polymerase chain reaction (PCR) and acute disseminated encephalomyelitis by pathological anatomy. The patient was treated with clarithromycin and had an uneventful evolution. At least to our knowledge, this is the first case in which M. pneumoniae DNA was detected by PCR in a brain biopsy.

INTRODUCTION: Acute gastroenteritis is a common disease in children. Rotavirus is the major etiologic agent. OBJECTIVES: To describe the epidemiological and clinical characteristics of acute gastroenteritis according to their etiology (rotavirus or other) in children younger than 5 years old in a private institution in the City of Buenos Aires. SECONDARY OBJECTIVE: to analyze related costs. MATERIAL AND METHODS: Cross sectional, descriptive, observational study conducted during one year in children younger than 5 years old with gastroenteritis. The presence of rotavirus was diagnosed with the VIKIA® Rota-Adeno test. Demographic, clinical and immunization data were collected. A univariate data analysis was performed. RESULTS: A total of 275 patients were included; 18.5% of them were R+. Rotavirus was more common in children younger than 2 years old and in the period between March and June. The cases of rotavirus gastroenteritis were more severe, required more hospitalizations (OR 2.07; 95% CI 1.17-7.13), and resulted in higher costs. In the sample studied, the immunization outcome measure reduced the risk of rotavirus infection. CONCLUSIONS: Acute gastroenteritis caused by rotavirus were different from other etiologies in that they had a seasonal peak and in relation to the median age of patients, the severity of the condition, the association with hospitalization and the increase in costs.

Introducción. La gastroenteritis aguda es una enfermedad frecuente en pediatría. Rotavirus es el principal agente etiológico. Objetivos. Describir las características epidemiológicas y clínicas de las gastroenteritis agudas según su etiología por rotavirus u otra en niños menores de 5 años en una institución privada de Buenos Aires. Objetivo secundario: evaluar los costos. Material y métodos. Estudio transversal, descriptivo, observacional, de un año de duración, en niños menores de 5 años con gastroenteritis. El rotavirus fue diagnosticado mediante la prueba VIKIA® Rota-Adeno. Se recolectaron datos demográficos, clínicos y de vacunación. Se realizó el análisis univariado de los datos. Resultados. Se incluyeron 275 pacientes; 18,5% fueron R+. Rotavirus fue más frecuente en los menores de 2 años y entre marzo y junio. Las gastroenteritis por rotavirus fueron más graves, requirieron más internaciones (OR 2,07; IC 95% 1,17 a 7,13) y provocaron más costos. En la muestra estudiada la variable vacunación redujo el riesgo de infección por rotavirus. Conclusiones. Las gastroenteritis agudas por rotavirus se diferenciaron de otras etiologías por tener un pico estacional, y por la mediana de edad, la gravedad, la asociación con internación y el aumento de los costos.
