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]
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
While the acronyms are similar, reactive airway disease (RAD) and reactive airways dysfunction syndrome (RADS) are not the same. [1]Reactive airways dysfunction syndrome was first identified by Stuart M. Brooks and colleagues in 1985 as an asthma-like syndrome developing after a single exposure to high levels of an irritating vapor, fume, or smoke.
The major criteria are: a persistent airflow limitation (a ratio of forced expiratory volume in 1 second divided by forced vital capacity of less than 0.7 or below the lower limit of normal), a significant exposure history to tobacco smoke (defined as a greater than 10-pack/year history), or significant exposure to other indoor or outdoor air ...
Bronchial hyperresponsiveness is a hallmark of asthma but also occurs frequently in people with chronic obstructive pulmonary disease (COPD). [2] In the Lung Health Study, bronchial hyperresponsiveness was present in approximately two-thirds of patients with non-severe COPD, and this predicted lung function decline independently of other ...
Should resting values be abnormal, then asthma, or some other chronic lung condition, is present. There is, of course, no reason why asthma and exercise-induced bronchoconstriction should not co-exist but the distinction is important because without successful treatment of underlying asthma, treatment of an exercise component will likely be ...
This is a shortened version of the eighth chapter of the ICD-9: Diseases of the Respiratory System. It covers ICD codes 460 to 519. The full chapter can be found on pages 283 to 300 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
The cause for acute severe asthma attacks is still unknown and experts are also unsure of why it developed and why it does not respond to typical asthma treatments.
