OBJECTIVES To estimate the occurrence of and associations between upper respiratory tract infections in preschool children, and to assess constitutional and environmental factors as determinants of these infections. DESIGN Population-based cross-sectional study. SETTING Oslo, Norway. PARTICIPANTS Preschool children, aged 4 to 5 years (3853 completed questionnaires). MAIN OUTCOME MEASURE...

With the focus on adult patients, children with an upper respiratory tract symptom should be suspected and screened for COVID-19 given mild presentation of disease in this population. We present a case 1-year-old who presented features turbinate dysfunction history suspect contact-mother.

Among critically ill patients with lower respiratory tract (LRT)-confirmed influenza, we retrospectively observed worse 28-day clinical outcomes in upper respiratory tract (URT)-negative versus URT-positive subjects. This finding may reflect disease progression and highlights the need for influenza testing of both URT and LRT specimens to improve diagnostic yield and possibly inform prognosis.

BACKGROUND ProSeal LMA (PLMA), one of the advanced supraglottic devices has been successfully used to provide both spontaneous and controlled ventilation in children with upper respiratory tract infection (URTI). URTI does not imply restriction of disease to upper respiratory tract; it has been shown to produce pulmonary dysfunction. PEEP has been shown to improve oxygenation in such cases. Thi...

sulfur mustard (sm) gas was used in the iran-iraq war (1981 - 1989) as a vesicant chemical warfare against the iranian warriors. this alkylating agent with the potential of producing chemical injury in the skin, eyes, and lung, may damage both upper and lower respiratory tract, which in turn can cause different types of sequels such as asthma, bronchiectasis, chronic bronchitis and lung fibrosi...
