It has been reported that angiotensin converting enzyme inhibitor (ACE-I) elicits dry cough more frequently in women than in men. This study was designed to evaluate whether airway cough receptors are more sensitive in women than in men. Cough threshold to inhaled tartaric acid was measured in 33
OBJECTIVE
The laryngeal cough reflex and the laryngeal cough expiratory reflex are brainstem reflexes that protect the upper airway from significant aspiration. The purpose of this investigation was to examine the effects of tartaric acid-induced cough on pulmonary function in normal healthy and
To evaluate the effect of chronic airway inflammation on cough sensitivity and bronchial responsiveness, we measured the cough threshold to tartaric acid and bronchial responsiveness to methacholine (PC20-FEV1) in 13 asthmatic, 13 bronchitic (sino-bronchial syndrome) and 49 healthy non-atopic
OBJECTIVE
The internal branch of the superior laryngeal nerve (ibSLN) conveys impulses for the laryngeal cough reflex, which protects the laryngeal aditus and prevents the development of aspiration pneumonia. The purpose of this study was to determine the effect of bilateral anesthesia of the ibSLN
There has been no detailed study of cough sensitivity during acute lower respiratory infection. The aim of this study was to clarify cough sensitivity in Mycoplasma pneumonia, which is a well known acute lower respiratory infection with persistent nonproductive cough. We examined cough sensitivity
The purpose of this study was to stimulate the laryngeal cough reflex using a nebulized, mild chemical irritant and to record an associated laryngeal evoked potential from the internal branch of the superior laryngeal nerve. The laryngeal evoked potential was obtained on ten normal subjects from the
BACKGROUND
The effect of the orally active local anaesthetic mexiletine on the cough response to two different tussive agents, a C-fibre ending stimulator capsaicin and a chemostimulant tartaric acid, was examined in normal subjects.
METHODS
The cough threshold, defined as the lowest concentration
BACKGROUND
The direct effect of bronchoconstriction on cough receptor sensitivity is unknown, and the antitussive effect of beta 2 adrenergic agonists in man has been controversial. This study was designed to throw light on these questions.
METHODS
The threshold of the cough response to inhaled
The threshold for cough induced by inhaled tartaric acid was measured in 71 non-atopic healthy volunteers. The cough threshold was lower in women than in men, which may be relevant to previous reports that angiotensin converting enzyme inhibitors induce cough more frequently in women than in men.
BACKGROUND
Cough is one of the most common symptoms of asthma. However, studies using capsaicin, citric acid, or tartaric acid to document cough threshold have repeatedly failed to show statistically significant differences between asthmatic and healthy subjects. The studies using hypertonic
We examined whether airway cough receptor sensitivity correlates to nonspecific bronchial responsiveness. We measured cough threshold, the lowest concentration of inhaled tartaric acid eliciting five or more coughs, and the provocative concentration of methacholine producing a 20% fall in forced
OBJECTIVE
The purpose of this study was to assess the effect of acute unilateral middle cerebral artery (MCA) infarctions in right-handed subjects on their ability to elicit voluntary cough (VC), and separately to assess the laryngeal cough reflex using the reflex cough test.
METHODS
This
BACKGROUND
Involuntary coughing such as that evoked from the larynx, the laryngeal cough reflex (LCR), triggers a coordinated contraction of the thoracic, abdominal and pelvic muscles, which increases intra-abdominal pressure (IAP), displaces the diaphragm upwards and generates the expiratory force
OBJECTIVE
The purpose of this study was to trigger the laryngeal cough expiration reflex using inhaled tartaric acid aerosol and to record the latency between the time of initiation of the laryngeal cough expiration reflex component of the laryngeal cough reflex and the onset of
OBJECTIVE
To determine the effectiveness of a new reflex cough test, using nebulized tartaric acid, in the evaluation of the laryngeal cough reflex and the development of aspiration pneumonia.
METHODS
In this two-phase study, the cough test assessed the cough reflex in 161 stroke subjects. Phase 1
