in this study, we aimed at studying the benefit of urtica dioica root extract in the management of allergic rhinitis. in a randomized double blind clinical trial, 74 patients with the signs and symptoms of allergic rhinitis and a positive skin prick test were randomly divided into 2 groups. the study group was treated with routine allergic rhinitis treatment and nettle root extract (urtidin®, b...

BACKGROUND Many published epidemiologic studies confirm a marked increase in the prevalence of asthma and allergic rhinitis. The link between allergic rhinitis and asthma has been extensively studied and approximately 75% of patients with asthma have allergic rhinitis. The proportion of patients with asthma in populations of allergic rhinitis patients has not been well studied. OBJECTIVE The ...

INTRODUCTION The guidelines on allergic rhinitis aim to update knowledge about the disease and care for affected patients. The initiative called "Allergic Rhinitis and its Impact on Asthma", initially published in 2001 and updated in 2008 and 2010, has been very successful in disseminating information and evidence, as well as providing a classification of severity and proposing a systemized tre...

BACKGROUND Rhinitis and obstructive sleep apnea (OSA) often coexist during childhood. To delineate this clinical association, we examined OSA severity and polysomnogram (PSG) features in children with rhinitis and OSA. Given that rapid-eye-movement (REM) sleep is characterized by nasal congestion, we hypothesized that children with rhinitis have more REM-related breathing abnormalities. METHO...

Allergic rhinitis causes major illness and disability worldwide, but it is still underdiagnosed and undertreated. Allergic rhinitis is a risk factor for both the development and for exacerbations of asthma. Up to 30% of patients with rhinitis suffer from asthma, and the majority of patients with asthma suffer from rhinitis. Measurements of allergic status can help to identify risk factors that ...

BACKGROUND Asthma and rhinitis are frequent respiratory diseases in children and adults. Despite the increase in the aging population, there are few epidemiologic data on both diseases in the elderly. So far, no population-based study has analyzed the association between asthma and rhinitis symptoms and severity in this age group. This study aimed to estimate the prevalence of physician-diagnos...

Background Asthma and allergic rhinitis have become a growing public health problem. The airflow obstruction, pathophysiological event that frames the bronchial asthma is usually determined by spirometry. Changes in expiratory flow in asthma are well known but there is controversy with these results in allergic rhinitis. The objective of this project is to compare spirometry values of young adu...

Allergic rhinitis in children is not an uncommon disease in India. Our objective was to evaluate the effect of allergic rhinitis on nasal mucociliary clearance. The nasal mucociliary clearance time (NMC) was studied using Andersen’s saccharin method in fifty controls and fifty age and sex matched patients of allergic rhinitis. The nasal mucociliary clearance time in healthy controls was found t...

Article type: Review Article Food allergy is estimated about 8% in children. The relationship between food and manifestation of allergy symptoms and its confirmation for accurate diagnosis is very important. Allergic rhinitis is a common disease with a prevalence of 40% among different societies. The prevalence of food-induced allergic rhinitis appears to be less than 1 percent. Food reactions ...
