background :respiratory viruses are the leading cause of respiratory tract infections among children and are responsible for causing morbidity and mortality worldwide. this study was performed to detect viruses in children with respiratory infections and describe their epidemiology and clinical characteristics.   methods : in this descriptive cross sectional study, throat swabs and wash specime...

The upper respiratory system includes the nose, nasal cavity, pharynx, and larynx with subglottic area of trachea. In the normal circumstances, air enters the respiratory system through nostrils where it is filtered, humidified, and warmed inside the nasal cavity. Conditioned air passes through pharynx, larynx, and trachea and then enters in lower respiratory system. Dysfunction of any part of ...

Community-acquired respiratory tract infections continue to be among the most common and important infections seen by practicing clinicians. These infections not surprisingly have some common aspects in regards to the microbes involved as well as their pathogenesis and typically involve the sinuses, the airways, and the lungs. Acute respiratory tract infections can be caused by a wide variety o...

Acute lower respiratory infections (ALRI) are the major cause of morbidity and mortality in young children worldwide. ALRIs are important indicators of the health disparities that persist between Indigenous and non-Indigenous children in developed countries. Bronchiolitis and pneumonia account for the majority of the ALRI burden. The epidemiology, diagnosis, and management of these diseases in ...

background renal scintigraphy with technetium 99m labeled dimercaptosuccinic acid (99mtc-dmsa) is a traditional imaging technique commonly used to detect renal scar in patients with probable vesicoureteral reflux (vur) and/or urinary tract infection (utis). we determined whether normal results of dmsa renal scan obviate the need for voiding cystourethrography (vcug) in evaluating children with ...

John Fry coined the phrase 'the catarrhal child' to describe the child we all know only too well with ever running nose whose desperate mother begs us to do something to staunch the flow of mucus. An understanding of the epidemiology and pathogenesis of upper respiratory tract viral infections may not enable us to stop the nose from running, but it can help us not to prescribe valueless medicat...
