Allergic rhinitis is inflammation of the nasal mucous membrane caused by exposure to inhaled allergenic materials that elicit a specific immunologic response mediated by immunoglobulin E (IgE). There are two types ... 

Titanium is so widely used that the risk of contact sensitivity to it must be very small. If a patient shows contact sensitivity to titanium, a replacement pacemaker should be completely encased in patch-tested non-allergenic material. 

Because allergenic food proteins are responsible for the sensitization and elicitation of allergic reactions, most detection methods have been based on the detection of these proteins. Alternatively, DNA has been suggested as a target for the detection of allergenic material in food. However, its use has been a controversial topic because the correlation between the presence of allergenic protein and DNA in processed food may not be constant. At least four factors may affect this correlation ...
