Ragweed is invading Europe, and climate change will make it worse

ragweedResearchers warn of growing health risks as invasive species creeps across the continent.

Ragweed pollen has made life miserable for allergy sufferers in Europe, and it's likely going to get much worse over the coming years, according to a study published today. By 2050, airborne pollen loads from the invasive species are projected to increase by a factor of four — largely due to climate change — pointing to what the paper's authors describe as an "urgent" need for action.

Penicillin allergy: A practical guide for clinicians.

Penicillin allergy is the most commonly reported drug allergy in the United States. However, after undergoing a complete evaluation by a board-certified allergist, including skin testing, 90% of patients labeled as 'penicillin-allergic' are able to tolerate penicillin. 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. Cross-reactivity between penicillin and other beta-lactams is less common than previously thought.

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. People muddle through the season with the excuse, allergies are annoying, but it’s “only” allergies. This too shall pass.

AAAAI calls for penicillin skin testing to slow antibiotic resistance


The American Academy of Allergy, Asthma and Immunology is calling for the use of penicillin skin testing to slow the development of antibiotic resistance, according to a press release.

An allergy to penicillin, which is reported by approximately 10% of the U.S. population, is linked with an unrecognized morbidity, which is receiving alternative antibiotics when penicillin would usually be the drug of choice. The problem with receiving alternative antibiotics, according to the release, is that they have been linked with higher costs, greater risk for adverse effects, longer hospital stays and encouraging resistant bacterial strains.
