Diseases of the upper airways are one of the most common diseases in childhood. Viral
infection of the upper airways is usually accompanied by the symptoms arising from
the tracheobronchial tree – especially by cough. It is important to state that the cough
is not a disease, but the cough is only a symptom. Children with recurrent or persistent
cough are usually treated inadequately – by inhaled corticosteroids or other anti asthma
drugs without exact diagnosis – they are over diagnosed as having asthma or cough
variant asthma, but without examination of bronchial hyperresponsiveness by methacholine
inhalation, capsaicin cough challenges, induced sputum or exhaled NO analysis.
The main proposal of this paper is to point out strong relationship between the upper
and the lower airways and mechanism potentially participating in the mediation
and modulation of the cough reflex in children suffering from rhinosinusitis. The paper
also characterizes very briefly some of the diseases linked with rhinosinusitis, which is
accompanied by cough – bronchial asthma, cough variant asthma, atopic cough, eosinophilic
bronchitis and postinfectious cough.
