title: [Development of occupational asthma. Follow-up R.F.E. of 23 cases].
abstract: Occupational asthma can either improve or develop into chronic respiratory insufficiency. It is often difficult to predict which course will be followed. Here we report the follow-up of respiratory function of 23 patients with occupational asthma of at least one year's standing, due to various substances; several prognostic factors are discussed.
