It is not possible to provide an accurate breakdown of the frequency with which other sites are etiologically involved, but in a large proportion of asthmatic patients in

Furthermore, since asthma is most often characterized by a multifactorial pathogenesis, it is also important to determine the exact role of the allergic phenomenon in each patient in order to choose an optimal preventive and therapeutic strategy.

Since these nebulizers produce dense aerosols (usually in excess of 3 ml of aerosol per minute), with a large proportion of respirable droplets [31], they were considered superior to the nebulizers and humidifiers avai

Definition and Classification of AsthmaThe history of the semantics of generalized reversible airway obstruction, “asthma,” is rather complex, but perhaps this is not so surprising. There are few conditions in which so many variables, endogenous and exogenous in nature, are involved, and these can provoke an immense variability in the phenotype of asthma.
