Cough Recognition is a valuable classification problem in healthcare. Generally, feature representation contributes a lot to the overall classifying performance. In this paper, a novel feature extraction method, Gammatone Cepstral Coefficients (GTCC), is investigated for cough recognition. The accuracy of GTCC comparing with MFCC is evaluated on a designed(More)
BACKGROUND Empirical therapy has been recommended as an initial clinical approach for treating gastroesophageal reflux-induced chronic cough (GERC). This study compared the predictive accuracy of the Gastroesophageal Reflux Disease Questionnaire (GerdQ) with the accuracy of multichannel intraluminal impedance pH monitoring (MII-pH) for GERC. METHODS A(More)
Gastroesophageal reflux induced cough is a common cause of chronic cough, and proton pump inhibitors are a standard therapy. However, the patients unresponsive to the standard therapy are difficult to treat and remain a challenge to doctors. Here, we summarized the experience of successful resolution of refractory chronic cough due to gastroesophageal(More)
BACKGROUND AND OBJECTIVE Little is known about non-acid gastroesophageal reflux-induced chronic cough (GERC). The purpose of the study is to explore the clinical characteristics of non-acid GERC. METHODS Clinical symptoms, cough symptom score, capsaicin cough sensitivity, gastroesophageal reflux diagnostic questionnaire (GerdQ) score, findings of(More)
OBJECTIVE To explore the diagnostic value and optimal cut-off point of symptom index (SI) in gastroesophageal reflux-induced chronic cough (GERC). METHODS The recordings of multichannel intraluminal esophageal impedance and pH monitoring were retrospectively analyzed in 118 patients with suspicious GERC. SI for all the refluxes, acid reflux and non-acid(More)
BACKGROUND Empirical three-step therapy has been proved in just one hospital. This study aimed to demonstrate applicability of the sequential empirical three-step therapy for chronic cough in different clinical settings. METHODS Sequential empirical three-step therapy was given to patients with chronic cough in one tertiary and three secondary care(More)
Gastroesophageal reflux (GER) is one of the most common causes of chronic cough, and chronic cough due to GER represents a subtype of GER-related diseases. Gastroesophageal reflux-induced chronic cough (GERC) can be divided into two subgroups based on the pH of the GER. Nonacid GERC is less common than acid GERC, and its diagnosis and treatment strategy(More)
Upper airway cough syndrome (UACS), previously referred to as postnasal drip syndrome, is one of the most common causes of chronic cough. However, the pathogenesis of UACS/postnasal drip syndrome remains unclear, and physicians in countries throughout the world have different definitions and ways of treating this disease. The various proposed pathogeneses(More)
