Can Skin Contact Cause Anaphylaxis?

Q: My daughter, who’s 7 years old, has dairy and other allergies and asthma, and has had one anaphylactic reaction. Then last fall, she broke out in big welts on her arms where another child’s milk spilled on her. (She did not get wheezing.) Is it possible to get anaphylaxis from skin contact with an […]

Are Quail Eggs Safe for Egg Allergy?

Q: If my child’s allergic to chicken eggs, could I safely cook for him using quail eggs? Dr. Sharma: People with allergy to hen’s eggs are generally also allergic to other bird eggs, including quail, turkey, duck, goose and seagull. This is called cross-reactivity, which occurs because of the similarity in the protein structures among […]

Advice on Idiopathic Anaphylaxis

Q: I have had four severe allergic reactions (wheezing, swollen eyelids, sneezing) but there was nothing common to each experience – nothing I could figure out, anyway. Two of the times I hadn’t even eaten anything. A skin test was inconclusive. My doctor called it “idiopathic anaphylaxis.” What do you suggest I do going forward?  […]

How Do You Know if an Allergy is Truly Gone?

Q: My 6-year-old daughter’s IgE blood test numbers for peanut allergy have significantly decreased, and the allergist is offering an oral challenge test. My question: as allergic reactions aren’t consistent, if she doesn’t react or has only minor symptoms on the day of the oral challenge, can we be certain this allergy is truly gone? […]

Do Reactions Worsen With Each Exposure?

Q: Is it true that food allergies to shrimp or peanuts will get worse with every accidental exposure? I had my first (quite bad) reaction to shrimp at 25 years of age, and this worries me. Dr. Sicherer: No, it is not true. It is a common myth that allergic reactions automatically become worse with […]

Can I Be Allergic to All Fish But One?

Q: My girlfriend has confirmed allergies to tuna, anchovies, shrimp, crab, clams and mussels. However, she can eat salmon with no issues. Does it make sense that she could be able to eat salmon but still be allergic to virtually every other creature of the sea? If so, could she consider trying squid or escargot? […]

Is it Possible to be Allergic to Kiwi?

Q: I recently fed my almost-3-year-old son kiwi, and he immediately complained that his “mouth hurt”. His top lip did appear somewhat swollen. We have no history of food allergies in the family, and he has eaten kiwi four or five times before without any reaction. I won’t give it to him again, but what […]

Can You Tell if a Food Allergy is Life-Threatening?

Q: What I don’t understand is: how does an expert decide whether a food allergy is “life-threatening” or not? This issue comes up frequently, such as when preparing forms for daycare or schools. Dr. Sharma: Your question is a great one because it points out a major limitation of our currently available food allergy tests, […]

Do Hand Sanitizers Protect Allergic Children?

Q: My child’s school insists hand sanitizers are adequate for cleaning up children after eating. But to protect allergic children, don’t they need to use soap and water? Dr. Sicherer: Antibacterial gels and foams do not remove debris from hands, they only kill germs. These sanitizers will not remove milk, peanut or even dirt from […]
