BACKGROUND Pseudomonas aeruginosa may cause severe or even fatal infection in hosts with immunodeficiency. Interleukin-17 (IL-17) is a newly discovered pro-inflammatory cytokine, which promotes the recruitment and activation of neutrophils in the respiratory tract by inducing release of chemokine C-X-C. OBJECTIVE This study was conducted to explore the role of IL-17 in host defense against ac...

BACKGROUND Viral respiratory infections are associated with nearly 80% of asthma exacerbation episodes. These can have severe adverse outcomes in patients with established asthma. AIM The aim of the study was to identify the viral causes of acute respiratory infection that precipitate acute asthma exacerbation in Egyptian asthmatic children. PATIENTS AND METHODS The current prospective stud...

Presence of specific IgM, IgG and IgA antibodies against Chlamydia pneumoniae was evaluated in children aged 1 week to 36 months to investigate the role of C. pneumoniae in respiratory infections and other diseases. Serum samples were obtained from 150 hospitalized children, including 123 children presenting the clinical symptoms of various respiratory tract infections, two children with acute ...

BACKGROUND The spectrum of neurologic disease attributable to Mycoplasma pneumoniae in children is incompletely understood in part because of limitations of microbiologic diagnostic methods. Our objective was to characterize the neurologic complications of M. pneumoniae in children using stringent diagnostic criteria. METHODS All children admitted to the Hospital for Sick Children over a 16-y...

Many years have passed since Flugge first drew attention to the probable importance, in the transmission of infection by way of the respiratory tract, of material expelled into air by infected individuals during the acts of talking, coughing, or sneezing. Infective particles disseminated in this manner manifest themselves in two forms: the moist state, in which many of the particles are relativ...

During August 2006-April 2010, in Beijing, China, 2 rare human enterovirus serotypes, coxsackievirus A21 and enterovirus 68, were detected most frequently in human enterovirus-positive adults with acute respiratory tract infections. Thus, during some years, these 2 viruses cause a substantial proportion of enterovirus-associated adult acute respiratory tract infections.

This study presents the first evidence of human bocavirus infection in South Korean children. The virus was detected in 27 (8.0%) of 336 tested specimens, including 17 (7.5%) of 225 virus-negative specimens, collected from children with acute lower respiratory tract infection.

We present a case of a middle-aged female who was admitted to the hospital with a respiratory infection and subsequently developed an acute surgical abdomen secondary to a perforated viscous. She was found to have mucormycosis of the intestinal tract and eventually succumbed to the sequelae of the infection.

Over six months Branhamella catarrhalis was isolated in pure culture from the sputum of 81 patients with symptoms of acute respiratory tract infection. Of 38 patients who were infected in the community, over half required admission to hospital. The remaining 43 patients acquired the infection in hospital. Forty one of the 81 isolates produced beta-lactamase, 24 of these being hospital acquired ...

BACKGROUND Acute viral respiratory infections are an important cause of morbidity and mortality in humans worldwide. The etiological backgrounds of these infections remain unconfirmed in most clinical cases. The aim of this study was to estimate the prevalence of human coronavirus infections in a series of children hospitalized with symptoms of acute respiratory tract disease in a one-year peri...
