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 assess the practicability of a new algorithm in decreasing the rate of incorrect diagnoses and inappropriate antibiotic usage in pediatric Acute Respiratory Tract Infection (ARTI). MATERIALS AND METHODS Children between 1 month to15 years brought to outpatient clinics of a children's hospital with acute respiratory symptoms were managed according to the steps recommended in the ...

Background: Acute respiratory viral infection (ARVI) is a common cause of morbidity and mortality especially in pediatric patients. Among important respiratory pathogens, adenovirus is a most prevalent cause of upper and lower respiratory tract infection. Objectives: The aim of the present study was to determine the prevalence of adenovirus infection in pediatric patients with respiratory sympt...

that may be isolated from the mucous membranes lining these structures. Although the lower respiratory tract is in direct continuity with the secretions draining the upper respiratory tract, it is, by contrast, normally sterile.2` This remarkable difference is brought about by a series of coordinated mechanisms of the mammalian host which act to protect the tracheobronchial tree and pulmonary p...

Ludwig’s Angina (LA) is an uncommon but potentially fatal cellulitis of the submandibular space, complicated by contiguous spread of infection within the respiratory tract and acute airway obstruction. A 13 month-old female developed LA following upper respiratory tract infection with Parainfluenza-3 virus. There was rapid deterioration due to acute airway obstruction and emergency endoctrachea...

Abstract Severe acute respiratory syndrome coronavirus 2 causing disease 2019 pandemic is an enveloped virus, showing genome similarity with bat coronavirus. This virus initially infects the upper tract, subsequent spread to lower tract. Despite availability of antigen and antibody detection methods, reverse transcription-polymerase chain reaction (RT-PCR) diagnostic test choice for this novel ...

this study was undertaken to determine the antibiotic sensitivity of 686 strains of hemolytic streptococci isolated at the school of public health, divi­sion of streptococcal studies, to five antibiotics in vitro. all of the strains were sensitive to penicillin, erythromycin, chloramphenicol and ampicillin. 27 (4%) of the strains, were resistant to tetracyclin. the clinical implications of this...
