Filter by:This is a randomized clinical trial that evaluates the impact of using an internet-based checklist for systematic assessment of patients reporting respiratory complaints with the conventional assessment, without using the checklist.
The purpose of this study is to determine the effectiveness of XEN-D0501 over placebo in reducing the daytime cough frequency in patients with chronic idiopathic cough. The effectiveness of XEN-D0501 over placebo in reducing capsaicin cough responses, objective 24-hour cough frequency, hourly change in cough frequency, cough severity (via visual analogue scale [VAS]), urge to cough (via VAS), global rating of change scale and Leicester Cough Questionnaire (LCQ) will be evaluated.
Although electronic cigarettes (e-cigs) are now widely used, very little information exists regarding the effect of electronic cigarette use (vaping) on the respiratory system. The aim of this study is to evaluate the acute effect of one e-cig vaping session (30 puffs 30 seconds apart) on cough reflex sensitivity in healthy adult nonsmokers.
The purpose of this research study is to test cough function in individuals with Parkinson's disease and healthy older adults. Cough is a complex, defensive function which involves movement of the chest and lungs. The investigators want to compare the movement of the chest wall and the lungs during voluntary and reflex cough. The long-term goal of this research is to develop treatments for people with cough dysfunction. Cough dysfunction increases the risk for respiratory infections such as pneumonia. The results from this study will provide information to help researchers understand the difference between reflex and voluntary cough more fully.
Idiopathic pulmonary fibrosis (IPF) is a devastating disease with no cure available. Patients suffer from respiratory symptoms including dyspnea and cough. To improve life quality the investigators will test the effects of immunomodulation of macrolides specifically on cough in IPF patients. The investigators hypothesize that immunomodulatory treatment reduces cough frequency and might improve lung function.
The objectives of this study are (a) to determine if drug levels from a single dose of an extended-release Codeine/Guaifenesin tablet are similar to an immediate-release tablet given every four hours containing lower doses considered safe for over-the-counter use; (b) to evaluate if food affects the drug levels of this extended-release Codeine/Guaifenesin tablet after a single administration; and (c) to assess the safety and tolerability of the Codeine/Guaifenesin extended-release and immediate release tablet formulations.
ABSTRACT: The aim of this study was to investigate the effect of betamethasone gel and lidocaine jelly (over tracheal tube cuff) compared with distilled water on the post intubation syndrome incidence. This study has not been carried out in Iran. 99 patients of either sex undergoing elective surgery were recruited in a single blind randomized study. The patients, using randomization table, were divided into three groups. Anesthetics and medications used during surgery were similar for all the patients. For the all patients, the incidence of postoperative sore throat, cough and hoarseness of the voice in the different follow-up periods (1, 6 and 24 hours) based on the different types of medications were obtained.
Despite its commonplace use in respiratory medicine the mechanism whereby inhalation challenge with a variety of mild acid aerosols produces a dose related and predictable cough is unknown. In this proposal the investigators wish to use established cough challenge methodology to explore the mechanism of action of agents provoking cough both in health and disease. The hypotheses to be tested include: - Intracellular changes in pH, rather than extracellular changes, are key in the activation of TRP receptors, the main sensor for provoking cough. - ATP acting through P2X channels is the mechanism of increased nerve excitability underlying cough hypersensitivity.
This study is to determine whether physiologic measures (peak cough flow, measures of respiratory muscle strength including MIP, MEP ,SNIP, and spirometry) can predict spontaneous cough clearance (as measured by a nuclear medicine study) in children with neuromuscular disease. It will also determine whether airway clearance is augmented by high frequency chest wall oscillation.
Post operative sore throat (POST) following tracheal intubation is a common problem causing dissatisfaction and discomfort to the patients. Prophylactic use of both lidocaine and dexamethasone has been used independently for this purpose. However, there is no study assessing the synergistic analgesic effects of lidocaine and dexamethasone for POST. The purpose of this study is to compare the effect of lidocaine, dexamethasone and lidocaine dexamethasone combination on the incidence and severity of POST.
