Comment:
This study depended on accurate diagnoses of asthma. However, it was unable to assess whether these patients indeed did have the disease. A study published in the CMAJ in 2008 concluded that 30 per cent of asthma diagnoses were incorrect.

Component-resolved diagnostics facilitate the diagnosis of peanut allergy
Journal of Allergy and Clinical Immunology
Not all peanut-sensitized children experience allergic reactions on exposure. Tests that could discriminate peanut allergy from tolerance without the need to perform oral food challenge would be extremely useful. Within the context of a population-based birth cohort, Nicolaou et al (p 191) determined, on the basis of peanut challenge, the proportion of children with peanut allergy among those considered peanut-sensitized using skin prick tests, sIgE measurements, or both (with whole peanut extract) and investigated whether blood tests with component-resolved diagnostics (microarray with major peanut and cross-reactive components) could differentiate peanut allergy from tolerance. Although approximately 1 in 10 children 8 years of age in the United Kingdom is peanut sensitized, on the basis of the oral food challenge, only 1 in 50 has peanut allergy. Component-resolved diagnostics revealed marked differences in the pattern recognition between subjects with peanut allergy and peanut-tolerant subjects (see Figure). Children with peanut allergy had higher responses to Ara h 1 to 3, whereas peanut-tolerant children had higher responses to grass components and cross-reactive carbohydrate determinants. Ara h 2 offered the best discrimination between the groups. These data confirm that the majority of children considered peanut sensitized on the basis of standard test responses do not have peanut allergy and suggest that measurement of IgE response to Ara h 2 might prove to be a clinically useful tool in predicting peanut allergy.

Air Canada ordered to create nut-free buffer zones
Comment:
This is a classic illustration of poor risk evaluation. There is no information available in this article to help me answer the basic questions when examining a health claim.
How many people suffer anaphylactic reactions on airplanes that require emergency treatment? How many have died? What is the incidence of these occurrences?
Has there been any evidence to show what the risk reduction would be with setting this policy? Will there be any subsequent evaluation to look at outcomes? And if the outcome demonstrates little to no reduction of risk or incidence, will there be a push to rescind this edict?
Have proactive measures by people who have nut allergies prior to boarding the plane been sufficient to prevent anaphylaxis?
This is a classic illustration of the precautionary principle eloquently discussed by this man.
An exerpt from the website Junkfood Science illustrates this point.
Food allergy deaths have only been tracked by the CDC since 1998, using death certificates coded using ICD-10 classifications (the 10th edition of the International Statistical Classification of Diseases). ICD-10 hasn’t yet been universally adopted, which makes the accuracy of its figure unreliable. It reports that of 2.5 million deaths among all ages in the U.S. in 2005, 11 people died from a food allergy in 2005, with the number from peanuts unknown.
Perhaps the most accurate population data on peanut-related deaths among children comes from the UK. Its national death statistics and pediatric surveillance system has recorded death statistics for nearly all children and it reported that only one child, a 15-year old, died from a peanut allergy between 1990 and 2000.
