Human rhinoviruses are the most common respiratory viruses detected in patients after hematopoietic cell transplantation. Although rhinovirus appears to occasionally cause severe lower respiratory tract infection in immunocompromised patients, the clinical significance of rhinovirus detection in the lower respiratory tract remains unknown. We evaluated 697 recipients transplanted between 1993 a...

The following principles of appropriate antibiotic use for adults with nonspecific upper respiratory tract infections apply to immunocompetent adults without complicating comorbid conditions, such as chronic lung or heart disease. 1. The diagnosis of nonspecific upper respiratory tract infection or acute rhinopharyngitis should be used to denote an acute infection that is typically viral in ori...

Background: Human parvovirus B19 was known as one of the possible cause of mild respiratory tract diseases in previous studies. However, there are some reports of acute obstructive respiratory disease and severe pneumonia. The purpose of current study was to assess the prevalence and clinical features of parvovirus B19 in respiratory infection.    Methods: This study was conducted on...

Background: Selective antibody deficiency with normal immunoglobulins (SADNI) may be identified as part of distinct primary or secondary immunodeficiency disorders. The clinical manifestations include recurrent, often severe or prolonged, upper or lower respiratory tract infections. Objectives: To evaluate SADNI in patients with recurrent sinopulmonary infections and its relation to IgG subclas...

objectives we assessed the prevalence of three common viruses including; respiratory syncytial virus (rsv), human rhinovirus (hrv), and human metapneumovirus (hmpv), in children with acute wheezing. patients and methods ninety six wheezy children, 48 males (50%) and 48 females (50%)under the age of 5 years, were enrolled in the study. all patients visited as outpatients or inpatients when refer...

BACKGROUND Dichlorodiphenyldichloroethylene (DDE) and other organochlorines suppress immunity biomarkers in animals and humans. Our aim was to study the association between prenatal levels of DDE and lower respiratory tract infection in infants independently from polychlorinated biphenyls (PCBs) and other organochlorines. METHODS Maternal levels of p'p'-DDE, dichlorodiphenyltrichloroethane (p...

Acute respiratory tract infection (ARI) is one of the leading causes of morbidity and mortality in paediatric age group. Acute respiratory tract infection is infection of any part of respiratory tract. According to WHO it can be graded as mild, moderate and severe. In the present study an attempt was made to retrospectively profile the cases of acute respiratory infections which presented to ou...
