OBJECTIVES To investigate 15 respiratory viruses in children with acute respiratory tract infections (ARTIs) using multiplex reverse-transcriptase polymerase chain reaction (RT-PCR), and to analyze the clinical and epidemiological features of these viruses. METHODS In a cross-sectional study, 135 children, ≤5 years of age who presented with ARTIs in Najran Maternity and Children Hospital, Naj...
The common cold is an acute, self-limiting, viral inflammation of the mucosa of the upper respiratory tract. It causes nasal discharge and congestion, sneezing, a sore throat and a cough. The common cold actually describes an array of similar conditions caused by a vast number of different viruses. It is most often caused by infection with rhinoviruses (50-80%) and coronaviruses [1] . It may al...
respiratory syncytial virus (rsv) is the major cause of lower respiratory tract infections in infants,and also an important factor for hospitalization during the winter months. to determine the prevalence and importance of rsv as a cause of acute lower respiratory tract infection, we carried out a prospective study during 5 months period from november to march 1998 in 6 pediatric hospitals. a n...
Objective: To investigate the correlation between respiratory syncytial viral load and length of hospitalization in infants with acute wheezing episodes. Methods: This was a two-year, cross-sectional study of infants ≤ 12 months of age with bronchiolitis at the time of admission to a tertiary hospital. For the identification of respiratory viruses, nasopharyngeal secretions were collected. Sa...
Background Rapid etiological diagnosis has a very important role in the clinical management of respiratory viral infections. Using a multianalyte point-of-care detection system, based on a fully automated immunoassay method, we can detect 8 respiratory viruses (influenza A and B viruses, parainfluenza 1, 2 and 3 viruses, respiratory syncytial virus, human metapneumovirus and adenovirus) and the...
Conventional respiratory viruses recovered from immunocompromised patients: clinical considerations.
Lower respiratory tract infection is the most common complication in the immunocompromised patient. From January 1991 to December 1995, 785 consecutive patients with suspected respiratory tract infections were studied. One hundred ninety-nine viruses were isolated from 182 (23%) of 785 bronchoalveolar lavage fluid specimens. Cytomegalovirus was isolated from 131 patients, herpes simplex virus w...
Detection of respiratory viruses by real-time multiplexed PCR (M-PCR) and of respiratory syncytial virus (RSV) by M-PCR and immunofluorescence (IF) was evaluated using specimens collected by nasopharyngeal flocked swabbing (NFS) and nasal washes (NW). In children with mild respiratory illness, NFS collection was superior to NW collection for detection of viruses by M-PCR (sensitivity, 89.6% ver...
OBJECTIVE Our objective was to demonstrate correlations between invasive pneumococcal disease in children and circulating respiratory viruses. METHODS This retrospective study included 6 winter respiratory viral seasons (2001-2007) in Intermountain Healthcare, an integrated health system in the Intermountain West, including Primary Children's Medical Center in Salt Lake City, Utah. Children <...
PURPOSE OF REVIEW The leading cause of death in solid organ and hematopoietic stem cell transplant recipients is infection. The respiratory viruses, particularly respiratory syncytial virus, influenza, parainfluenza, adenovirus, and picornaviruses, are increasingly recognized as significant pathogens in these populations. RECENT FINDINGS Respiratory syncytial virus has again been found to be ...
Acute otitis media (AOM) is a common complication of upper respiratory tract infection whose pathogenesis involves both viruses and bacteria. We examined risks of acute otitis media associated with specific combinations of respiratory viruses and acute otitis media bacterial pathogens. Data were from a prospective study of children ages 6 to 36 months and included viral and bacterial culture an...
