Non-allergic rhinitis is defined by the absence of positive SPTs or radioallergosorbent test (RAST) to common allergens. Ideally, it should include a negative response to likely nasal allergen challenge since local nasal IgE synthesis has been demonstrated. In practice, the diagnosis is usually dependent on there being no offending allergen apparent from the clinical history. As advancing age is associated with reduced IgE levels and a reduced prevalence of positive SPTs, this may be a confounding factor when assigning rhinitics into atopic and non-atopic subgroups. Such age-related changes contribute to the fall in the apparent prevalence of allergy among persistent rhinitics from around 80% in childhood to below 20% in elderly people. Epidemiologic studies of a population of nearly 3000 patients in Tucson, Arizona, have shown that the prevalence of symptoms of allergic rhinitis is as high as 30% even in those with very low ageadjusted serum IgE scores. This emphasizes that there is a nonallergic subgroup to rhinitis. (more…)

Another kind of pain reliever those are popular as analgesic is acetametaphin (Tylenol). NSAIDs work by curbing the enzyme cyclooxygenase-1 (COX-1) or cyclooxygenase-2 (COX-2) or both of them at the same time. (more…)
