One of the first accounts documenting that it is the exposure of the colonic mucosa to latex balloons that contain the barium, rather than the barium itself, that cause allergic reactions during barium enema radiologic examinations. Natural rubber latex NRL is a milky fluid obtained from the Hevea brasiliensis tree, which is widely grown in south-east Asia. However, contact dermatitis from thiuram leached from latex gloves may also occur. Thiurams, carbamates, and benzothiazoles can be confirmed as allergens by patch testing. These reactions occur without an immunologic mechanism.
Latex - management of a patient at risk of or with a known latex allergy
