Typically, the age of onset is childhood asthma, but throughout my experience in Pneumology have seen their appearance at any age. Overall life expectancy, especially in the absence of smoking, does not differ from the normal population.
Approximately 3% of cases of chronic asthma associated with smoking, morbid obesity, the coexistence of infections, vocal cord dysfunction or NSAID hypersensitivity, is difficult to control and can be altered.
Late-onset asthma may be related to occupational exposures or drugs. The mortality below 30 years should be minimal in a country like ours, with sanitation coverage and abundance of centers.
Treatment of bronchial asthma
Overall treatment today is very grateful and it is good that the patient knows existing drugs and how they are managed. In difficult cases, it helps the patient self-control systems available as Peak-Flow-Meter.
The exaggerated fear of some patients to steroids is a barrier to treatment. For difficult cases they are being introduced different biological drugs. "Refinement" of vaccines is another treatment advances. Both beta-adrenergic such as short length combined with inhaled corticosteroids or not, control 95% of patients
The diagnosis is generally straightforward: spirometry with bronchodilator test, Peak Flow before and after sport, or more continuous graphics, provocation test, levels of IgE, specific IgE, exhaled nitric oxide, oscillometry flow in more babies, studies CT or other image, contribute to a more accurate affiliation.
In short, this has been only a cursory review and remember: the snuff in the parents favored asthma in children, although the snuff is not the direct cause of asthma, asthma and snuff mixture is like gasoline and fire.
Do not think of "The Hand That Rocks the Cradle", think of the number of Olympic medals in asthmatics.
