Background: Respiratory virus infections represent a major public health problem because of their worldwide occurrence, ease of spread in the community and considerable morbidity and mortality. They are one of the most common reasons for hospitalization of children under the age of six. In some cases, infection with two different viruses increase the severity of disease which lead to the h...
Acute infection of the lower respiratory tract comprises bronchitis, bronchiolitis, and pneumonia. From a clinical point of view it may be diYcult to distinguish these disease entities and one infection may progress into another. The most common pathogens causing these infections are the primary respiratory viruses (respiratory syncytial virus (RSV), influenza virus, adenoviruses, parainfluenza...
The aim of this study was to determine whether interleukin (IL)-8 is released within the upper respiratory tract of infants during respiratory syncytial virus (RSV) bronchiolitis and whether the large number of polymorphonuclear neutrophils (PMNs) present in the respiratory tract of these infants are contributing to the inflammation through release of inflammatory mediators. Twenty-seven infant...
OBJECTIVES To describe the pattern of infectious diseases among children admitted from a residential child care centre and to identify any unusual clusters of admissions. DESIGN Retrospective case review. SETTING Regional hospital, Hong Kong. PATIENTS All children from a residential child care centre aged over 28 days who were admitted from the Accident and Emergency Department to paediat...
background and aims: respiratory syncytial virus (rsv) infection is common in infants and young children. in infants younger than one year old it may cause bronchiolitis and pneumonia which requires hospitalization. accurate and rapid diagnosis of the disease will help proper treatment of the disease and prevents further complications. methods: specimen taken from respiratory tract of sick chil...
Comprehensive population-based data on the role of respiratory viruses in the development of lower respiratory tract infections (LRTIs) remain unclear. We investigated the incidence and effect of single and multiple infections with respiratory viruses on the risk of LRTIs in Vietnam. Population-based prospective surveillance and a case-control study of hospitalised paediatric patients with acut...
Background: Human respiratory syncytial virus (HRSV) is the most important viral agent of acute lower respiratory tract disease in infants and young children worldwide. This virus is responsible for 50% brochiolitis and 25% pneumonia in infants. There are limited data of molecular epidemiology of HRSV from developing countries. This is the report on the molecular epidemiology of human respirato...
It is not known whether respiratory syncytial virus spreads beyond the respiratory tract. With the use of reverse transcriptase polymerase chain reaction, we found viral and transcribed RNA in cells from the arterial blood of four children with bronchiolitis but none in serum or cerebrospinal fluid. Respiratory syncytial virus might therefore spread outside the respiratory tract.
AIM In our study, we aimed to clinically and epidemiologically evaluate respiratory tract infections the viral agents of which were detected by molecular methods and to compare influenza and other respiratory tract viruses in this context. MATERIAL AND METHODS The records of 178 patients aged above 2 years who presented to pediatric emergency outpatient clinic with fever and respiratory tract...
