In examining 379 patients with asthma, I1 found vasomotor rhinitis in 145 (38 per cent). The incidence was highest among those with specific allergic asthma, about 47 per cent; among those with so-called pathergic asthma it was 37 per cent. When the vasomotor rhinitis appeared at about the same time as the asthma, the conditions were brought on by the same causal agents, and when the vasomotor rhinitis appeared long before or after the asthma, the conditions were attributable to different agents.
The present contribution is an analysis of 74 cases of vasomotor rhinitis in which there was no history of asthma or any evidence of asthma at the time of examination. The patients had presented themselves for treatment only of refractory nasal conditions. They were examined in 1936 and 1937 in my allergy department in the Krankenhaus der Kaufmannschaft, in Vienna, according to a uniform plan of procedure, described
