Exposure to tobacco smoke has been associated with harmful effects on child health. The association between tobacco smoke exposure and childhood rhinitis has not been established in developed or developing countries. We investigated the association between serum cotinine levels and rhinitis in a population sample of 1,315 Asian children. Serum cotinine levels were positively associated with rhi...

The aim of this study was to investigate the clinical and pathological significance of interleukin 31 (IL-31), interleukin 33 (IL-33), and thymic stromal lymphopoietin (TSLP) in serum of patients with asthma and/or rhinitis. The levels of IL-31, IL-33, and TSLP were measured by enzyme-linked immunoadsorbent assays in serum samples from 64 cases of asthma patients, 64 cases of rhinitis patients,...

BACKGROUND A close relation between asthma and allergic rhinitis has been reported by several epidemiological and clinical studies. However, the nature of this relation remains unclear. We used the follow-up data from the European Community Respiratory Health Survey to investigate the onset of asthma in patients with allergic and non-allergic rhinitis during an 8.8-year period. METHODS We did...

Pasteurella multocida toxin (PMT) is a protein toxin found in toxigenic strains of Pasteurella multocida. PMT is the causative agent for atrophic rhinitis in pigs, a disease characterized by loss of nasal turbinate bones due to an inhibition of osteoblast function and an increase in osteoclast activity and numbers. Apart from this, PMT acts as a strong mitogen, protects from apoptosis and has a...

This document contains complete guidelines for diagnosis and management of rhinitis developed by the Joint Task Force on Practice Parameters in Allergy, Asthma and Immunology, representing the American Academy of Allergy, Asthma and Immunology, the American College of Allergy, Asthma and Immunology and the Joint Council on Allergy, Asthma and Immunology. The guidelines are comprehensive and beg...

OBJECTIVE We aimed to analyze health-related quality of life (HRQOL) in adults with newly diagnosed respiratory allergy according to the sensitization profile for relevant aeroallergens in their usual area of residence. METHODS We performed a cross-sectional, epidemiological, observational, descriptive, multicenter study in allergy clinics in Spain. The sample comprised adults diagnosed with ...

BACKGROUND Allergic rhinitis is the most frequent chronic allergic disease in children, and may be an important risk factor for the subsequent development of asthma. OBJECTIVE To describe the characteristics of patients younger than 14 years of age presenting with rhinitis and the possible association with asthma. METHODS We carried out a prospective, observational, descriptive, cross-secti...

BACKGROUND The existence of a local allergic rhintis was proposed on the basis of the detection of nasal IgE in the absence of a systemic sensitization. Nevertheless, the significance of this phenomenon remains still unclear. We assessed the presence of mucosal nasal IgE in patients with ascertained allergic rhinitis, nonallergic rhinitis with inflammation and in healthy controls. METHODS Con...

OBJECTIVE To describe the frequency and etiology of rhinitis, oral breathing, types of malocclusion and orofacial disorders in patients treated for dental malocclusion. METHODS Patients with poor dental occlusion (n=89, 8-15 years) undergoing orthodontic treatment at the Postgraduate Orthodontics Center (Sao Paulo, Brazil) participated in the study. Rhinitis and oral breathing were diagnosed ...

The aim of this study was to investigate the association between Mycobacterium tuberculosis (MBT) infection and atopic rhinitis in children recruited from a community with high incidence of MTB infections. The children were assessed for rhinitis according to the ISAAC questionnaire and tested for MTB infection by the tuberculin skin test (TST). Allergen-specific IgE sensitizations were tested b...
