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...

Background: Rhinitis, which occurs most commonly as allergic rhinitis and affects 20% of the world’s population, is a major health care burden causing significant morbidity. Considering the high prevalence of allergic rhinitis and anti-inflammatory effects of thyme, a favorite condiment, we performed a randomized clinical trial to determine whether thyme can relieve allergic rhinitis symp...

the link between allergic rhinitis and asthma is well known. bronchial hyperreactivity (bhr) may be present in rhinitis. the present study was aimed to compare airway responses in patients  with rhinitis symptoms alone following exercise challenge, and to  determine relationship of two different respiratory function tests. 98 subjects with rhinitis were investigated by spirometry and impulse os...

Background Allergic rhinitis is one of the most common types of rhinitis. Allergen avoidance is the most important way of preventing this disease. The present study is carried out to determine the frequency of common aeroallergens in patients with allergic rhinitis in Gorgan city by skin prick test (SPT) reactivity. Materials and Methods  In this cross-sectional study 270 patients referring t...

Introduction: Allergic rhinitis (AR) is a common airway disease. In order to study  the  prevalence of  AR in high school students  in  Kerman, the Score for Allergic Rhinitis (SFAR) was used and the quality of life  in  the  students  affected  by  rhinitis was  evaluated using the SF-36 questionnaire.   Materials and Methods: This was a cross-sectional, analytical, descriptive study, based o...

BACKGROUND The affliction of allergic rhinitis (AR) has been trivialised in the past. Recent initiatives by the European Academy of Allergy & Clinical Immunology and by the EU parliament seek to rectify that situation. The aim of this study was to provide a comprehensive picture of the burden and unmet need of AR patients. METHODS This was a cross-sectional, online, questionnaire-based study ...

The 146-kDa Pasteurella multocida toxin (PMT) is the main virulence factor to induce P. multocida-associated progressive atrophic rhinitis in various animals. PMT leads to a destruction of nasal turbinate bones implicating an effect of the toxin on osteoblasts and/or osteoclasts. The toxin induces constitutive activation of Gα proteins of the G(q/11)-, G₁₂/₁₃- and G(i)-family by deamidating an ...

Nasal hyperresponsiveness (NHR) is a characteristic feature of allergic rhinitis (AR); however, the pathogenesis of NHR is not fully understood. In this study, during the establishment of an experimental AR model using ovalbumin-immunized and -challenged mice, augmentation of the sneezing reaction in response to nonspecific proteins as well as a chemical stimulant was detected. Whether NHR is i...
