That is the good news, but the tragedy of asthma deaths continues. Most of this improvement is related to effective preventer therapy using inhaled corticosteroids. These have saved lives.

Clinical presentation is key in classifying reactions as either mediated by or not mediated by immunoglobulin E (IgE), and in determining which patients may benefit from penicillin skin testing, graded-dose challenge, or desensitization.

Kid Having Trouble in School? Maybe It’s Allergies

Spring is in the air, and business at our office is humming. At this time of the year, we not only see lots of patients, but receive requests from the media to answer questions. Year in year out, the advice doesn’t change much—avoid pollen if you can, take antihistamines and maybe nasal steroids, and think about getting immunotherpy–allergy shots. This year there are a couple of tablets on the market, which Larry has written about. The tenor of most discussion is highly familiar.
