Nasal Polyps

Broadly defined, nasal polyps are abnormal lesions that originate from any portion of the nasal mucosa or paranasal sinuses. Polyps are an end result of varying disease processes in the nasal cavities. The most commonly discussed polyps are benign semitransparent nasal lesions (see the images below) that arise from the mucosa of the nasal cavity or from one or more of the paranasal sinuses, often at the outflow tract of the sinuses. Multiple polyps can occur in children with chronic sinusitis, allergic rhinitis, cystic fibrosis, or allergic fungal sinusitis. Some of these can treated medically by allergists - thus avoiding surgery!

HUman Stem Cell Lawsuit Dropped

A lawsuit that challenged the National Institutes of Health’s human embryonic stem cell research funding policy has been thrown out.

The lawsuit argued that the NIH’s policy violated the 1996 Dickey-Wicker amendment, which prohibits the federal government from funding research that harms human embryos. The NIH’s policy, which is supported by the Obama administration, provides funding for research that uses approved stem cell lines derived from embryos using private funding.

Epinephrine Autoinjector is Very Important in the Treatment of Food Allergy

Epinephrine is the treatment of choice for anaphylaxis. Delay in administration of epinephrine is a known risk factor for food allergy reaction-related mortality; however, individuals with food allergy may not have epinephrine readily available. In a recent study (Allergy and Asthma Proceedings, Volume 32, Number 4, July/August 2011 , pp. 295-300), it was found that many children do not have their epinephrine autoinjectors readily available despite parental report. Epinephrine autoinjector training improved the odds of having an epinephrine autoinjector readily available. Continued patient education on the importance of having an epinephrine autoinjector easily accessible, especially when eating, is important. So ask your allergist on how and when to administer this life saving intervention in your child!

2011 Ragweed Season Begins

“Climate change creates longer ragweed season”

 Ragweed season has begun in the New York/New Jersey metropolitan area with the first sighting by Dr. Bielory, a National Allergy Bureau certified pollen counting station.  Three out 4 Americans who have allergies are allergic to ragweed pollen. The earlier sighting appears to be consistent with Dr. Bielory’s report. that climate change may be affecting pollen release and earlier development of allergies.

A changing climate means allergy-causing ragweed pollen has a longer season that extends further north than it did just 16 years ago and in New Jersey appears to increasing in duration of exposure with earlier pollination and longer release days. As part of an ongoing study by Dr. Leonard Bielory and the researchers at Rutgers University and the U.S. Department of Agriculture, funded in part by the U.S. Environmental Protection Agency. According to the study published n the Proceedings of the National Academy of Sciences, allergy experts found that ragweed pollen season lasted as much as 27 days longer in 2009 than it did in 1995 with increasing range northward resulting in a more dramatic the change in the length of pollen season. Allergies associated with ragweed pollen (to which 3 out of 4 Americans who are allergic have ragweed allergies – also known as hay fever) costs about $21 billion a year in the United States. At one time this was hypothesized and modeled as a possibility – “but it is a reality” according to Leonard Bielory, M.D. who is leading the investigation for the U.S. EPA – “this is affecting patients now!” Ragweed is not the only pollen season affected as the study will be evaluating the impact on tree and grass pollen seasons that occur n the early and late spring.

As global average temperatures have warmed, the first frost has been delayed, especially at higher latitudes, which has meant a longer season for ragweed. Because warming is greater at these high latitudes, the length of the season has been more pronounced.

From the report the ragweed season actually shrank by 4 days between 1995 and 2009 in Texas while further north it was noted to be 11 days longer in Nebraska; 16 days longer in Minnesota; and 27 days Saskatchewan in Canada. In New Jersey, the season appears to have increased over the past 20 years, but not as prolonged as the differences noted in Canada. This appears to eventually impact on the diagnosis of allergies that could coincide with the flu season. Primary care physicians may under-diagnose and undertreat allergies since they would not be familiar with such a change in the allergy season and thus may require the assistance of an allergist to confirm the diagnosis to maximize the treatment for their patients. 

"Allergies that have been minor in the past are going to increase and become more of a clinical problem that may also impact patients with asthma!” Bielory said.
