Carrot Anaphylaxis in a Birch Pollen-Allergic Patient

It is early spring and the trees are budding.  A 28 year old woman presents for evaluation of an allergic reaction.  She has a history of spring hayfever and recently was also prescribed Prevacid for dyspepsia.  A few days later after eating raw carrots she developed widespread urticaria with abdominal cramps.  

She reported no recent NSAID or alcohol ingestion. She has no prior food or medication allergies.   She is still taking Prevacid (lansoprozole). 

Skin testing was positive to tree pollen and birch tree.

Skin testing to carrot was negative.

Did the carrots cause the reaction and why now?   My theory was that her Birch-specific IgE increased during allergy season which in turn crossreacted with carrot, a well know...

What's So Affordable about the Affordable Care Act?

A few of my patients decided to save money and buy health insurance through the ACA health exchanges.  I can't blame them for wanting to save money but they quickly discovered that neither I nor any of their doctors accept that insurance.  As a result they are now paying out of pocket as they scramble to switch to other plans. This pattern will repeat itself.  People who are unin...

What Medicare Pays Your Colleagues

The NY Times ran an article yesterday about a very small minority of physicians (none of whom are allergists) who account for a sizable portion of medicare payments.  Surprisingly the top 2% of doctors collect nearly 25% of Medicare payments.

Doctor, What Triggered My Recent Allergy/Asthma Flare? There's an App for that now!

It's actually more than an app, it's a platform that was the subject of a featured poster at the 2014 AAAAI annual meeting.  Patients enter data on their smartphone (through the Asthma Ally app on Iphone/Android/Windows) which then sends a GPS tag with timestamp to the cloud platform.  The env...

Misguided by the FeNO

I recently saw a patient for a 2nd opinion.  He was a previously healthy nonatopic man in his 20's who had been experiencing chest pain and dyspnea for a couple of months.  There were no other upper or lower airway symptoms.  He was diagnosed with asthma by a well-regarded pulmonologist.  The PFTs were normal but the FeNO was elevated at 75 ppb which was the basis for starti...

Adult Eosinophilic Esophagitis: A response to PPI is not diagnostic of reflux

 The patient with esophageal eosinophilia (>15/hpf) may have either reflux or eosinophilic esophagitis (EoE).  Ideally a patient would undergo pH testing and if negative one could conclude that the condition is EoE.  However, many patients are reluctant to have the 24 hr pH study.  As a result the response to PPI has been considered a surrogate for the diagnosis of reflux...

Otolaryngologists Treating Asthma

It was recently called to my attention that the February 2014 edition of the Otolaryngologic Clinics of North America is devoted to the screening, diagnosis, and management of asthma.   The justification is that ENTs who are already providing allergy care should treat asthma as a "convenience" for their allergic patients. ...

About This Blog

This blog is about allergy from my perspective as a private-practice doctor who teaches, occasionally publishes, and also works in human rights. After over 10 years in practice, it is clear to me that a better understanding of sinus disease and functional laryngeal disorders is required to be an allergy and respiratory disease specialist. I will share my insights with you as I try to bridge the divide between bench and bedside as well as between allergy and otolaryngology. Like my medical practice, this blog is about the clinical, ethical, and health economics issues of the day. Your thoughts and comments are always appreciated.
Disclosure: Gary J. Stadtmauer, MD, has disclosed no relevant financial relationships.

Poll: Have any of your patients died of an asthma attack? Yes, related to noncompliance|Yes, due to asthma severity alone|No|
