1. Viral etiology of acute respiratory infections in children in Southern Iran
Abstract INTRODUCTION: Prevalence of influenza A virus (Flu-A), respiratory syncytial virus (RSV), and human metapneumovirus (hMPV) was assessed in children with acute respiratory infections (ARIs). METHODS: Nasopharyngeal aspirates and throat swabs were subjected to real-time polymerase chain reaction (PCR) to detect RSV and Flu-A and to conventional PCR

2. Bronchiolitis Hospitalization in Southern Brazil from 2002 to 2012: A Count Time-series Approach
Abstract INTRODUCTION: Because the antibody neutralizing respiratory syncytial virus (anti-RSV) has a short period of immunization and high cost, the identification of regions and months of highest occurrence of bronchiolitis is very important. METHODS: An Autoregressive Conditional Poisson model was constructed for count data and compared to the standard

3. Human metapneumovirus in Southern Brazil
Abstract INTRODUCTION Infections caused by respiratory viruses are important problems worldwide, especially in children. Human metapneumovirus (hMPV) is a respiratory pathogen and causes severe infections with nonspecific symptoms. This study reports the hMPV occurrence and dissemination in southern Brazil and compares the frequency of occurrence of this v

4. Respiratory syncytial virus seasonality in Brazil: implications for the immunisation policy for at-risk populations
Respiratory syncytial virus (RSV) infection is the leading cause of hospitalisation for respiratory diseases among children under 5 years old. The aim of this study was to analyse RSV seasonality in the five distinct regions of Brazil using time series analysis (wavelet and Fourier series) of the following indicators: monthly positivity of the immunofluoresc

5. Detection of respiratory viruses by real-time polymerase chain reaction in outpatients with acute respiratory infection
Viruses are the major contributors to the morbidity and mortality of upper and lower acute respiratory infections (ARIs) for all age groups. The aim of this study was to determine the frequencies for a large range of respiratory viruses using a sensitive molecular detection technique in specimens from outpatients of all ages with ARIs. Nasopharyngeal aspirat

6. Viral epidemiology of respiratory infections among children at a tertiary hospital in Southern Brazil
Introduction This study reports the pediatric epidemiology of respiratory syncytial virus (RSV), influenza (IF), parainfluenza (PIV), and adenovirus (ADV) at Hospital de Clínicas de Porto Alegre. Methods Cases of infection, hospitalizations in intensive care units (ICUs), nosocomial infections, and lethality rates were collected from 2007 to 2010. Resu

7. A survey strategy for human respiratory syncytial virus detection among haematopoietic stem cell transplant patients: epidemiological and methodological analysis
Human respiratory syncytial virus (HRSV) causes severe infections among children and immunocompromised patients. We compared HRSV infections among Haematopoietic Stem Cell Transplant program (HSCT) patients and children using direct immunofluorescence (DFA), point-of-care RSV Bio Easy® and a polymerase chain reaction (PCR) assay. Overall, 102 samples from H

8. Profilaxia da infecção por vírus sincicial respiratório: estudo clínico prospectivo de crianças submetidas ao uso de palivizumabe. / Prophylactic treatment of infection by the sincycial respiratory virus: prospective clinical study of infants to the use of palivizumab.
Respiratory Syncytial Virus (RSV) is the most important etiologic agent in acute lower respiratory tract infections (ALRTIs) in children under two years, with high rates of hospitalization and death in high risk children for severe RSV infection. Objective: To identify the virus present in acute respiratory tract infections (ARTIs) and to analyze rates of ho

9. Ensaio clínico controlado e randomizado para avaliação da eficácia da azitromicina no tratamento da bronquiolite aguda / Ensaio clínico controlado e randomizado para avaliação da eficácia da azitromicina no tratamento da bronquiolite aguda / Ensaio clínico controlado e randomizado para avaliação da eficácia da azitromicina no tratamento da bronquiolite aguda
Rationale: Acute viral bronchiolitis is a leading cause of hospitalization in the first year of life. Several studies have shown that macrolides have immune modulating properties, but only a few and underpowered trials have tested the efficacy of these antibiotics in infants with acute bronchiolitis. In this study we tested the hypothesis that azithromycin r

10. Respiratory syncytial virus, infants and intensive therapy
The aims of this study were to determine the presence of respiratory syncytial virus (RSV) and to assess the clinical features of the disease in infants with acute low respiratory tract infection hospitalized at pediatric intensive care units (PICU) of two university teaching hospitals in São Paulo State, Brazil. Nasopharyngeal secretions were tested for th

11. Detection of human bocavirus and human metapneumovirus by real-time PCR from patients with respiratory symptoms in Southern Brazil
The introduction of newer molecular methods has led to the discovery of new respiratory viruses, such as human metapneumovirus (hMPV) and human bocavirus (hBoV), in respiratory tract specimens. We have studied the occurrence of hMPV and hBoV in the Porto Alegre (PA) metropolitan area, one of the southernmost cities of Brazil, evaluating children with suspect
