The objective of the present study was to determine the impact of influenza virus on pediatric hospitalized patients. We retrospectively reviewed records of children with laboratory diagnoses, by cell culture and/or indirect immunofluorescence assay, of influenza virus seen in a period of 6 years. A total of 1,033 samples were analyzed, 45 (4.3%) of them being reactive to influenza virus. Thirty-one samples were positive to influenza A virus and 14 to influenza B. The frequency of hospitalization in intensive care and medical emergency was found to be high. Three (8.6%) patients died, two of them due to respiratory failure. Low frequency of influenza virus infection was observed in the study. The data suggest the need of more efficient epidemiological... |

OBJECTIVES: Mycoplasma pneumoniae is an atypical pathogen, which is one of the major causes of lower respiratory tract infections (LRTIs) worldwide. This study was performed to determine the role of M. pneumoniae in acute LRTIs in children, who were referred to main pediatric hospitals in Shiraz, Iran, with the diagnosis of LRTI. Polymerase chain reaction method on a throat-swab specimen was utilized to detect M. pneumoniae. RESULTS: One hundred patients with acute LRTIs were investigated in this study. There were 10 positive PCR for M. pneumoniae (10%), including 6 of 62 hospitalized patients and 4 of 38 outpatients. All patients with LRTIs due to M. pneumoniae had cough. Fever, flu like symptoms, dyspnea, pulmonary rales, wheezing, and conjunctivitis... |

Aims: To determine the frequency of viral pathogens causing upper respiratory tract infections in non-hospitalized, symptomatic adults in the city of Rio de Janeiro.Methods:Respiratory samples (nasal/throat swabs) were collected between August 2010 and November 2012 and real time PCR was used to detect different viral pathogens.Results:Viruses were detected in 32.1% (43/134) of samples from 101 patients. Specifically, 9% (12/134) were positive for HBoV, 8.2% (11/134) were positive for HAdV, 5.2% (7/134) were positive for HRV, and 1.5% (2/134) were positive for FLUBV or HMPV, as single infections. HRSV-A, HPIV-3, and HCoV-HKU1 were detected in one (0.75%) sample each. Co-infections were detected in 4.8% (6/134) of the samples. Peaks of viral infections were... |

Respiratory syncytial virus (RSV) is responsible for annual respiratory infection outbreaks in infants and young children worldwide, frequently causing bronchiolitis and pneumonia. We evaluated clinical and epidemiological features of acute respiratory infections (ARIs) caused by respiratory syncytial virus (RSV) in children less than five years old. Nasopharyngeal aspirate samples from children with ARI symptoms, attended at the 'Hospital das Clínicas' - Federal University of Uberlândia, MG, Brazil, were collected and tested for RSV by the immunofluorescence assay (IFA). Patients' clinical and epidemiological data were also obtained. From April 2000 to June 2003, 317 nasopharyngeal samples were collected from children less than 54 months old. Seventy-six... |
