background: allergic rhinitis is one of the most common forms of allergic disorders affecting children. the prevalence rate of allergic rhinitis differs among countries and even among regions within the same country.   objectives: to determine the prevalence of childhood allergic rhinitis and the presence and significance of eosinophilia in nasal secretions.   method: 4584 children aged 11-15 y...

"Nonallergic rhinopathy" was defined by consensus at a Roundtable conference in December 2008 as "a chronic nasal condition with symptoms that may be perennial, persistent, intermittent or seasonal and/or elicited by recognized triggers." The definition includes a well-recognized set of clinical exposures that lead to the symptoms, predominantly congestion, rhinorrhea, and postnasal drip. These...

Allergic diseases represent a major public health problem worldwide. The frequency of allergic rhinitis in the general population is 10-20%, 68% which seasonal rhinitis. In 57.14% patients with rhinitis, initial vagotonia combined predominantly over-provisioning activity hyperdiastolic type was found. According to severity course exacerbation 18,25% had mild course, 57,94% - medium and 23,81% s...

BACKGROUND The strong interactions between asthma and rhinitis, and the influence of rhinitis in the severity and/or control of asthma, have clearly been demonstrated. Nevertheless, no specific study has been conducted in the occupational setting. OBJECTIVE The aim of the study was to assess the severity of occupational asthma and rhinitis and evaluate whether rhinitis is a predictor for incr...

Vasomotor rhinitis is the most common form of nonallergic rhinitis, comprising approximately 71% of all nonallergic rhinitis conditions. Although the epidemiology of this subtype of nonallergic rhinitis has not been definitively studied, it is estimated that 14 million Americans suffer from vasomotor rhinitis, with a worldwide prevalence approaching 320 million.

Studying associations between sibship characteristics and allergic diseases in detail may contribute clues to their etiology. The authors studied associations between sibship characteristics and risk of self-reported allergic rhinitis and asthma among 31,145 pregnant women participating in a nationwide study in Denmark during 1997-2000. Increasing sibship size was associated with a decreased ri...

Many patients have nasal syndromes that are nonallergic and noninfectious and not caused by mechanical or anatomic abnormalities. There are at least 8 recognized nonallergic rhinitis syndromes: drug-induced rhinitis including rhinitis medicamentosa, gustatory rhinitis, hormonally induced rhinitis including the rhinitis of pregnancy, nonallergic rhinitis with eosinophilia syndrome, senile rhinit...

allergen immunotherapy involves the administration of gradually increasing quantities of specific allergens to patients with ige-mediated conditions until a dose is reached that is effective in reducing disease severity from natural exposure. in the present study we evaluated a period of six years immunotherapy allergic rhinitis and allergic asthma patients with positive skin prick test of comm...

the prevalence of allergic diseases such as asthma and allergic rhinitis is high in general population and aeroallergens are the most common allergens that cause air way inflammation. the aim of this study was an evaluation of clinical and laboratory findings in allergic patients and identification of the most common aeroallergen in these patients. a cross–sectional retrospective study was cond...
