title: [Occupational asthma].
abstract: Occupation Asthma is defined as an illness characterized by the existence of a variable limitation of one's air flow or a bronchial hyper-reactivity due to causes and conditions attributed to a determined labor medium and not to stimuli found outside one's work place. We can distinguish two main types of occupational asthma, based on the most likely mechanism involved in causing it: an immune type asthma which has a latent period and includes all those cases which have a proven or probable immune mechanism; and a non-immune type which is manifested by a reactive dysfunction in the respiratory channels syndrome, or in other words, by asthma induced by irritating agents.
