The proximal location of the disease prevented radical therapy and the patient eventually died from chronic sepsis. [ABSTRACT FROM PUBLISHER]

Kveim tests were done in forty-eight patients with Crohn's disease. Of forty-five with definite or probable Crohn's disease, twenty-three had a positive Kveim test.
