[Clinical, diagnostic and therapeutic aspects of non-allergic forms of rhinitis: non-allergic rhinitis with eosinophilia syndrome and vasomotor rhinitis].

Two clinical syndromes of non-allergic rhinitis -- NARES and vasomotor rhinitis -- were studied. In recent years there has been a moderate statistical increase in both conditions which are still not easily diagnosed or treated, given the fact that they are often confused with allergic rhinitis. In this context a brief review of aetiopathogenic and physiopathological factors is followed by the suggestion of certain elements that may be assessed in order to obtain a more correct classification and diagnosis. Finally the drugs providing a more effective and long-lasting cure are listed.
