The relationship was studied between preschool and current respiratory symptoms and cough receptor sensitivity in children. Forty six white children aged 7 years were investigated. They were divided into three groups: (i) healthy children; (ii) children with a history of idiopathic cough; and (iii) children with a history of wheezing. Cough receptor sensitivity was assessed by the inhalation of...

OBJECTIVES To review the literature on habit, tic, and psychogenic cough, and to make evidence-based recommendations regarding diagnosis and treatment. DESIGN/METHODOLOGY For data on adults, an Ovid MEDLINE literature review (through February 2005) was performed for all studies published in the English language, including case series and case reports, since 1966 using the medical subject head...

BACKGROUND Cough is a defensive behavior that can be initiated in response to a stimulus in the airway (reflexively), or on command (voluntarily). There is evidence to suggest that physiological differences exist between reflex and voluntary cough; however, the output (mechanistic and airflow) differences between the cough types are not fully understood. Therefore, the aims of this study were t...

BACKGROUND Cough is one of the most frequent symptoms in children and is the most common symptom for which children visit a health care provider. METHODS This is an observational study on acute cough associated with upper respiratory tract infection (URTI) in children. The study evaluates the epidemiology and impact of cough on quality of sleep and children's activities, and the outcome of co...

We tested the hypothesis, motivated in part by a coordinated computational cough network model, that alterations of mean systemic arterial blood pressure (BP) influence the excitability and motor pattern of cough. Model simulations predicted suppression of coughing by stimulation of arterial baroreceptors. In vivo experiments were conducted on anesthetized spontaneously breathing cats. Cough wa...

PURPOSE The present study aimed to examine the age and gender distributions among chronic cough patients referred to a tertiary cough clinic in Korea, and to investigate clinical factors related to the demographic findings. METHODS Study participants were unselectively recruited from adult chronic cough patients who attended the cough clinic for the first time during one year. To validate the...
