The primary aim of this study was to evaluate the frequency and seasonality of norovirus infection in hospitalized Polish children under 5 years of age, and a secondary aim was to compare the clinical severity of norovirus and rotavirus disease. The prospective surveillance study was carried out from July 2009 through June 2010. Stool samples from 242(More)
Adhesion molecules play a key role in leucocyte migration into the central nervous system (CNS). Concentrations of endothelial-derived soluble intercellular adhesion molecule-1 (sICAM-1) and leucocyte-originated soluble L-selectin (sL-selectin) in cerebrospinal fluid (CSF) of children with mumps meningitis (mononuclear pleocytosis, n = 33) and mumps(More)
Toxocariasis is a worldwide distributed zoonotic disease. Soil contaminated with Toxocara eggs appears to be the main source of infection for humans. The aim of our study was to estimate the environmental contamination with Toxocara eggs in public areas in northeastern Poland followed by the assessment of seroprevalence of toxocariasis in the children’s(More)
We measured levels of pro-inflammatory cytokines in the cerebrospinal fluid (CSF) of patients with mumps meningitis, enteroviral echovirus 30 meningitis and children without central nervous system infection to investigate whether these molecules were involved in the pathogenesis of viral meningitis. The CSF was obtained from 62 children suspected with(More)
Matrix metalloproteinases are involved in leucocyte invasion into the central nervous system (CNS) during meningitis. The aim of the study was to determine whether there are differences in the expression patterns of matrix metalloproteinase-9 (MMP-9) and the tissue inhibitor of metalloproteinase-1 (TIMP-1) in the cerebrospinal fluid (CSF) of patients with(More)
BACKGROUND Matrix metalloproteinases (MMPs) are crucially involved in central nervous system inflammation. This study assesses preanalytical factors on MMP-2 concentrations in cerebrospinal fluid (CSF). METHODS The concentrations of MMP-2 in CSF obtained from 13 patients were measured using ELISA. Identical measurements were done from the samples of the(More)
PURPOSE The aim of the study was to establish the main etiologic agents of acute viral gastroenteritis and to asses the severity of illness associated with the different viral agents of gastroenteritis in children hospitalized during spring/summer season 2008. MATERIAL AND METHODS 181 stool specimens were collected from children under 5 years of age,(More)
Recently, we have developed the new dressings containing rhG-CSF or rhGM-CSF. In the present study we investigated either in vitro or in vivo biological activity of the dressings. Human whole blood samples were incubated with extracts from the collagen- or polyurethane-based dressings containing rhG-CSF or/and rhGM-CSF and phagocytic and oxidative metabolic(More)
OBJECTIVES The purpose of this study was to determine the main causative agents of community-acquired acute diarrhoea in children using conventional methods and PCR. METHODS Stool samples were collected from 100 children under 5 years of age with acute diarrhoea during the autumn-winter period of 2010-2011. Rotaviruses and adenoviruses were detected by(More)
