Reactive airways dysfunction syndrome: occurrence after exposure to a refractory ceramic fiber-phosphoric acid binder mixture.
A previously healthy, 47-year-old millwright was exposed to high airborne levels of a refractory ceramic fiber-phosphoric acid binder mixture; after acute bronchospasm, he required hospitalization. During the next 4 years, he had recurrent acute bronchospasm requiring emergency department visits and three hospitalizations. Review of the patient's medical and occupational history and extensive clinical investigation failed to provide alternate explanations for this hyperresponsive airways disease. This is believed to be the first reported case of reactive airways dysfunction syndrome (RADS) after exposure to a refractory ceramic fiber-phosphoric acid binder mixture. Physicians should be aware of this possibility when examining patients exposed to such materials.
