❏ Diagnostic algorithm for patients with chronic productive cough outlined. A chronic 'productive' or 'wet' cough is a common presenting complaint for patients attending the adult respiratory clinic. Most reviews and guidelines suggest that the causes of a productive cough are the same as those of a non-productive cough and as such the same diagnostic pathway should be followed. Although it see...
RATIONALE Speech language pathology is an effective management intervention for chronic cough that persists despite medical treatment. The mechanism behind the improvement has not been determined but may include active cough suppression, reduced cough sensitivity or increased cough threshold from reduced laryngeal irritation. Objective measures such as cough reflex sensitivity and cough frequen...
Tonsillar enlargement is sometimes seen in patients with otherwise unexplained chronic cough although its significance is unclear. In this study, the authors set out to test the hypothesis that cough symptoms and cough reflex sensitivity will improve after tonsillectomy in patients with otherwise unexplained chronic cough and enlarged tonsils. Eight consecutive patients with unexplained chronic...
The aim of the present study was to determine whether the ability to suppress cough voluntarily is an index of cough severity in upper respiratory tract infection. Cough was measured by means of a microphone linked to a pen recorder and subjects were instructed to voluntarily suppress cough in order to determine cough suppression time. Subjective scores of symptom severity, mood and psychologic...
BACKGROUND Cough is one of the most common reasons for visiting a clinic. The causes of cough differ according to the duration of cough. Infectious disease is commonly observed in acute cough while noninfectious disease is commonly observed in chronic cough. On the other hand, cough is frequently observed in patients with asthma/cough variant asthma (CVA). OBJECTIVE In this study, we investig...
BACKGROUND We have described a group of patients who present with isolated chronic bronchodilator resistant non-productive cough with an atopic constitution, eosinophilic tracheobronchitis, and airway cough receptor hypersensitivity without bronchial hyperresponsiveness, which we have termed "atopic cough". Although cough variant asthma (in which the cough responds to bronchodilators) is recogn...
A cough that has no medical diagnosis and does not respond to treatment is sometimes labeled as psychogenic cough, habit cough, or tic cough. These disorders should be distinguished from other forms of chronic cough, but there is little consistency or evidence on how to best diagnose a chronic cough as a psychogenic, habit, or tic cough. The American College of Chest Physicians (ACCP) has updat...
BACKGROUND Substance P (SP) is involved in the pathogenesis of cough in animal models. However, few studies in humans have been reported and the roles of SP in clinical cough remain obscure. OBJECTIVES To clarify the relevance of plasma levels of SP in patients with persistent cough. METHODS We studied 82 patients with cough persisting for at least 3 weeks and 15 healthy controls. Patients ...
Chronic cough is common, blights patients' lives and is hard to treat. Chronic cough patients demonstrate high objective cough rates and as a group have increased cough reflex sensitivity. However, conventional cough challenge techniques show substantial overlap with normal subjects. This suggests that other important mechanisms have yet to be determined. For the last two decades, chronic cough...
