Actinobaculum schaalii may be a more common urinary tract pathogen than previously described. Here we report four cases of A. schaalii UTIs and we also propose a simple identification scheme to be used in the conventional microbiology laboratory based on standard biochemical tests.
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.
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.
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.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
