‘Three things cannot be hidden: coughing, poverty and love’. This is originally Yiddish proverb, quoted in many texts and movies, which may well describe the hypersensitive nature of cough (1). The cough reflex is a primary airway defense mechanism against aspiration, but when dysregulated, it becomes a problem commonly presenting as irresistible bouts with hypersensitivity to various innocuous environmental or behavioral triggers (2). Importantly, cough is a common problem in general populations and is the single most common symptom for medical visits (3-5).
A major change during the recent decade is a paradigm shift in chronic cough. The recognition of cough hypersensitivity as the key pathophysiological mechanism underlying chronic cough has opened a new window of opportunity in the management of chronic cough (6,7). Now we are getting more understanding of this disease condition, recently termed “cough hypersensitivity syndrome” by the European Respiratory Society Taskforce report (8). Thus, the Journal of Thoracic Disease (JTD) initiated a dedicated section for Cough in 2016, which was led by Prof. Peter Dicpinigaitis (9), and now aims to continue its vision to promote our understanding and refine our clinical strategy for cough. The Cough Section will feature original studies as well as state-of-the-art reviews, opinion papers, and selected letters. We hope this section could serve as a good field for scientific communication and enhancing creativity for cough. We invite clinicians and scientists to submit their works to the Cough Section of the JTD.
