Systemic contact dermatitis from subcutaneous hydromorphone

We report a patient who developed a generalized dermatitis after a period of progressive local intolerance to continuous subcutaneous infusion of hydromorphone for cancer pain. Sensitization to hydromorphone was proved by a positive patch test. Infusions with an equianalgesic dose of diacetylmorphine were well tolerated, without local or systemic side-effects, and prolonged the duration of infusion sites.     

Allergic contact dermatitis from cardamom

A case is presented of a confectioner with a chronic hand dermatitis and positive patch test reactions to cardamom and certain terpenoid compounds present in the dried ripe seeds of cardamom. Cardamom is a popular traditional flavouring agent for baked goods and confectionery. Dermatitis from skin exposure to cardamom has to the best of our knowledge not been reported. We report one case of allergic contact dermatitis to cardamom elicited by terpenes present in the seeds.
