Goals & Objectives: To understand the differential diagnosis and management of common causes of pediatric cough: • List the common etiologies for chronic cough in children, differentiating between specific and non-specific cough and “wet” and “dry” cough. • Understand the management of chronic, non-specific cough, including trials of therapy for cough-variant asthma and protracted bronchitis. •...

Chronic cough is a very common complaint in clinics throughout China. Clinical and basic science research on chronic cough started late, but in recent years the effort has yielded promising findings regarding the etiological diagnosis, treatment and pathogenesis. We found that inflammation in nonasthmatic eosinophilic bronchitis has some similarities to cough variant asthma but also a number of...

OBJECTIVE We explored the relationship between atmospheric concentrations of fine particulate matter and children cough variant asthma. PATIENTS AND METHODS 48 children all diagnosed with cough variant asthma were placed in the cough asthma group while 50 children suffering from typical asthma were place in typical asthma group. We also had 50 cases of chronic pneumonia (the pneumonia group) ...

Airway eosinophilia and cough may be associated with asthma and with non-asthmatic eosinophilic bronchitis. Whether cough variant asthma and eosinophilic bronchitis are distinct entities or a pathophysiological spectrum needs further examination.

Cough is one of the most common complaints for which patients seek medical attention. Misdiagnosis and mistreatment of cough exist commonly in China. The prevalence of acute cough caused by upper airway infection fluctuates between 9% and 64% in the community, for chronic cough, the prevalence >10% in most surveys, ranging from 7.2%-33%. The common causes of chronic cough are upper airway cough...
