Abstract

451 rural children (group I) and 2000 urban children (group II) aged 10-16 years from Toruń province were inquired by a questionnaire to their parents or guardians. 9.09% of children in the country and 13.45% of those living in the city of Toruń suffered from hypersensitivity disorders; bronchial asthma was reported in 2.22% and 3.05% of cases, allergic rhinitis--in 3.77% and 7.15%, allergic conjunctivitis--in 1.33% and 2.75%, allergic edema--in 0.44% and 0.60%, urticaria--in 1.55% and 3.50%, and infantile eczema--in 0.44% and 2.10% of cases, respectively. The pollinosis prevalence rate was 2.00% in group I and 1.85% in group II. At least 2 various forms of hypersensitivity coexisted in 30.48% of allergic urban children (64.86% of patients with pollinosis among them); infantile eczema preceded allergic rhinitis and bronchial asthma symptoms in 6.29% and 11.47% of cases, respectively, while allergic rhinitis occurred before the onset of bronchial asthma in 24.59% of asthmatic children. 37.10% of individuals with positive family history of allergic conditions also fell ill with some diseases of this nature, while in those with negative family history allergy occurred only in 10.22% of cases.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.

Allergies & Environmental Factors

Environmental factors are strongly associated with the prevalence of allergies and are an increasing health concern worldwide. Discover the latest research on Allergies and Environmental Factors here.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
