Giving children and adolescents with egg allergy small but increasing daily doses of egg white powder holds the possibility of developing into a way to enable some of them to eat egg-containing foods without having allergic reactions, according to a study supported by the National Institutes of Health (NIH). The study results will appear online in the July 19th issue of the New England Journal of Medicine [1].
The emerging field of epigenetics has added a new dimension to the “nature versus nurture” debate, by which researchers have historically attempted to determine whether a characteristic was influenced by genes or environment. Increasingly, it appears that environmental influences can affect gene expression, meaning that “nature” and “nurture” are inextricable from one another to an even greater extent than previously understood.

The prevalence of peanut allergies in preschool and school age children in the UK, the US and Canada is between 1.2 – 1.6%, which is about twice the rate at which it occurs in adults in these countries. Nut allergies, especially peanut allergies, are scary. And although they have been on the rise, no one really knows why. Researchers in Scotland recently reported in The Journal of Allergy and Clinical Immunology that mutations in the gene for filaggrin, a protein found in skin, are a “significant risk factor for peanut allergy” [1].
Seasons Greetings! Welcome to the Holiday Edition of Grand Rounds, featuring some of the best articles of the biomedical and healthcare blogosphere.
At this time last year, I announced the Highlight HEALTH Network, a single source that aggregates content from all the Highlight HEALTH websites. This year, I have a similar gift for biomedical and healthcare blogosphere readers:
