AERD affects an estimated 0.3–0.9% of the general population in the US, including around 7% of all asthmatics, about 14% of adults with severe asthma, and ~5-10% of patients with adult onset asthma. [2] [3] [8] AERD is uncommon among children, with around 6% of patients, predominantly female, reporting disease onset during childhood. [9]
Research by sports scientist John Dickinson found that 70 percent of UK-based members of the British swimming team had some form of asthma, as did a third of Team Sky cyclists, compared to a national asthma rate of eight to ten percent, [24] whilst a study by the United States Olympic Committee in 2000 found that half of cross-country skiers ...
Approximately 17% of all adult-onset asthma cases are related to occupational exposures. [21] About one fourth of adults with asthma have work-exacerbated asthma. [4] Patients with work-related asthma are more likely to experience asthma attacks, emergency room visits, and worsening of their asthma symptoms compared with other adult asthma ...
Use of dexamethasone 4–8 mg IV q 8 - 12 h in cases where airway edema may be the cause of the stridor; note that some time (in the range of hours) may be needed for dexamethasone to work fully. Use of inhaled Heliox (70% helium, 30% oxygen); the effect is almost instantaneous. Helium, being a less dense gas than nitrogen, reduces turbulent ...
These medications include short-acting beta agonists (SABAs) such as albuterol which typically last 4–6 hours, and long-acting beta agonists (LABAs) such as salmeterol which lasts 12 hours. [5] For example, during an acute asthma exacerbation where airway smooth muscle is constricted, inhalation of SABAs provide rapid relief of symptoms ...
This acts to impair airflow and cause shortness of breath, stridor and often discomfort in the throat and upper chest. EILO is a very common cause of breathing difficulties in young athletic individuals but is often misdiagnosed as asthma or exercise-induced bronchoconstriction. [1] [2]
Laryngotracheal stenosis is an umbrella term for a wide and heterogeneous group of very rare conditions. The population incidence of adult post-intubation laryngotracheal stenosis which is the commonest benign sub-type of this condition is approximately 1 in 200,000 adults per year. [10]
[4] Additionally, the pediatric population is more susceptible to disease and complications from bronchospasm due to their airway diameter being smaller; applying Poiseuille's Law to the airways it is clear that airflow resistance through a tube is inversely related to the radius of the tube to the fourth power, therefore, decreases in airway ...
