The impact of viral infections on childhood central nervous system infections.

Background: Viruses are a common cause of central nervous system (CNS) infections. However, studies of CNS viral pathogens in pediatric patients are poorly explored because viral infections are often erroneously diagnosed as bacterial infections.

Methods: 299 CNS samples were collected from pediatric patients aged from one month to 14 years old.

Trabecular bone score: a useful clinical tool for the evaluation of skeletal health in women of short stature.

Purpose: Areal bone mineral density (aBMD) by DXA is underestimated in those with smaller bones and overestimated in those with larger bones. Trabecular bone score (TBS) predicts fracture risk, and is not influenced by bone size. The aim of this study was to evaluate TBS and BMD in women with short stature.

Central and peripheral nervous system involvement in Zika virus infection in a child.

A 7-year-old boy that presented an encephalomyeloradiculitis and no classic symptoms of arboviruses. Zika virus (ZIKV) was confirmed by molecular analyses of cerebrospinal fluid and 1 year later by plaque reduction neutralization test. This case demonstrates that ZIKV can be associated with diffuse nervous system infection in children.

Meningitis Associated with Simultaneous Infection by Multiple Dengue Virus Serotypes in Children, Brazil.

To determine the causes of viral meningitis, we analyzed 22 cerebrospinal fluid samples collected during the 2014-2015 dengue epidemics in Brazil. We identified 3 serotypes of dengue virus (DENV-1, -2, and -3), as well as co-infection with 2 or 3 serotypes. We also detected the Asian II genotype of DENV-2.
