    Acoustic rhinometry and rhinomanometry are important tests used to assess nasal function. The degree to which the parameters of these tests are correlated is yet to be established. OBJECTIVE: This paper aimed to study the correlations between nasal resistance (NR) and acoustic rhinometry parameters in children and adolescents with allergic rhinitis and controls. METHOD: Twenty patients with allergic rhinitis and 20 controls were enrolled. NR, volumes (V4, V5, V2-5), and minimal cross-sectional areas (MC1, MC2) were measured in three moments: baseline, after induction of nasal obstruction and after topical decongestant administration. RESULTS: Patients with allergic rhinitis had significant correlation between NR and all volumes (V5: r = -0.60) and with MC2. Among controls, MC1 was the parameter with the strongest correlation with NR at baseline (r = -0.53) and after decongestant administration. In the combined analysis, V5 had the highest correlation coefficients at baseline (r = -0.53), after obstruction (r = -0.58) and after decongestant (r = -0.46). CONCLUSIONS: Our data showed that NR and acoustic rhinometry parameters have negative and significant correlations. Nasal volumes are, in general, better correlated than minimal cross-sectional areas. V5 was the parameter with the highest correlation in the rhinitis group and in the combined analysis.

    OBJECTIVES: There is a high incidence of intestinal parasite infection in urban areas in the Northeast of Brazil. Giardia lamblia infections have been associated with increased prevalence of cutaneous allergies and gastrointestinal disorders. However, little is known about the relationship between giardiasis and allergic diseases of the airways. The present study aimed to investigate the possible association between respiratory allergic diseases and infections by G. lamblia in children from urban areas. METHODS: This study recruited 110 patients of both sexes aged 5-15 years. Patients were administered a questionnaire evaluating clinical symptoms and were given skin tests, parasite tests and serum tests. RESULTS: A high incidence of G. lamblia was observed (45%, 50/110). Infections by this protozoan were not associated with increased risk of respiratory allergy (p = 0.075), high total IgE levels (p = 0.701), positive specific IgE tests (p = 0.250), or positive skin tests for a range of environmental allergens (p = 0.239). CONCLUSION: This study demonstrated that symptoms of asthma, skin allergy and serum markers were not associated with G. lamblia infections in this sample of children from urban areas.

    Prevalência de sintomas de asma, rinite e eczema atópico entre crianças e adolescentes brasileiros identificados pelo International Study of Asthma and Allergies (ISAAC): fase 3

    OBJECTIVE: To determine the prevalence of symptoms of asthma, rhinitis, and atopic eczema among schoolchildren aged 6 to 7 years and adolescents aged 13 to 14 years in 20 Brazilian cities by using the standardized ISAAC written questionnaire, and to assess the association of this prevalence with latitude, altitude and average annual temperature of collaborating centers. METHODS: Schoolchildren and adolescents from five Brazilian regions participated in the study, totaling 23,422 ISAAC questionnaires answered by schoolchildren's parents and 58,144 questionnaires answered by adolescents. The values for latitude, altitude and average annual temperature were obtained from the Brazilian Institute of Geography and Statistics. RESULTS: The mean prevalence rates among schoolchildren and adolescents were respectively 24.3 and 19.0% for active asthma; 12.6 and 14.6% for rhinoconjunctivitis; and 8.2 and 5.0% for atopic eczema. A significant negative association was observed between latitude and physician-diagnosed asthma among schoolchildren, severe asthma, physician-diagnosed asthma, eczema and atopic eczema among adolescents. No association with altitude was found. CONCLUSIONS: The prevalence of asthma, rhinitis and atopic eczema in Brazil varies considerably. Higher prevalence rates, especially of asthma and eczema, were found at centers located closer to the equator.
