Iаn is а surgicаl nurse and has wоrked in the ER fоr the past seven years. Over the past twо years, he has begun to show symptoms of latex sensitivity, causing a rash approximately 12 hours after wearing latex gloves. One day, a surgeon accidentally broke a glove and sprayed a fine latex mist around Ian. Within minutes, Ian had collapsed to the floor and was unable to breathe. He was stabilized, treated, and returned to work shortly after. A few weeks later Ian began to get a tingling sensation in his mouth after eating bananas and avocados. A skin-prick test subsequently determined that Ian was allergic to bananas, avocados, and kiwis (even though he had never eaten kiwis in his life). His immunologist also reviewed his early medical history and found that as a child Ian had a reaction to penicillin. About three weeks after he started taking the medication, he developed a rash, achiness, and a fever. His symptoms resolved within about seven days.
