Nonallergic rhinitis (NAR) conditions are currently considered diagnoses by exclusion. A diagnosis of NAR requires negative specific IgE responses by skin or serologic testing and more recently testing to exclude localized production of specific IgE in the nose. Symptoms are classically aggravated by irritant triggers such as tobacco smoke, perfumes/fragrances, and temperature or barometric pre...

Allergic rhinitis is a global health problem. Over 600 million patients suffer from this disease worldwide. ARIA (Allergic Rhinitis and its Impact on Asthma), an evidence-based document, was produced and published in 2001 using an extensive review of the available literature. The ARIA 2008 update was recently published and covers tertiary prevention of allergy, pharmacologic treatments, and imm...

OBJECTIVES The purpose of the study was to compare cytological and biochemical changes in nasal lavage fluid induced by wheat flour inhalatory challenge in bakers with allergic rhinitis and with asthma accompanied by rhinitis. MATERIALS AND METHODS A single-blind, placebo controlled study was conducted in 64 bakers with allergic rhinitis (n = 17), bronchial asthma and rhinitis (n = 24) and wi...

Local allergic rhinitis (LAR) is a localized nasal allergic response in the absence of systemic atopy. The aim of this study was to evaluate the prevalence and clinical characteristics of LAR in Korean rhinitis patients compared to allergic rhinitis (AR) and non-allergic rhinitis (NAR). A total of 304 rhinitis patients were enrolled from November 2014 to March 2016. A skin prick test, serum tot...

Wood dusts are known to cause respiratory disorders like rhinitis and asthma. This study was therefore done to determine the magnitude of the problem among woodworkers in south-eastern Nigeria exposed to high level of wood dust. Five hundred and ninety one woodworkers were selected using a stratified random sampling. The prevalence of woodwork-related rhinitis and asthma were then observed in t...

Introduction: Submucoperichondrial injection of botulinum neurotoxin A (BTA) in the nasal septum is a promising therapeutic option in the treatment of persistent allergic rhinitis (AR) and non-allergic rhinitis, and is safer and more effective than intraturbinate injection in reducing clinical symptoms.   Materials and Methods: Forty patients diagnosed with persistent AR or non-allergic rhiniti...

Introduction: Allergen immunotherapy is an effective treatment for allergic rhinitis. Conventional immunotherapy takesat least 5 to 6 months to reach the maintenance dosage; nonetheless, rush immunotherapy accelerates to reach the maintenance dose several months earlier. However, the safety and efficacy of this treatment has not been widely investigated. The objective of the present study...

INTRODUCTION The hygiene hypothesis proposes that reduced exposure to infections in early life increases the risk of developing allergic conditions including allergic rhinitis. We examined the association between markers of the hygiene hypothesis and allergic rhinitis that developed before 7 years of age and allergic rhinitis that developed after 7 years of age. METHODS The Tasmanian Longitud...

BACKGROUND The link between upper and lower airways in patients with both asthma and allergic rhinitis is still poorly understood. As the biological complexity of these disorders can be captured by gene expression profiling we hypothesized that the clinical expression of rhinitis and/or asthma is related to differential gene expression between upper and lower airways epithelium. OBJECTIVE Def...

Asthma and rhinitis are often co-morbid conditions. As rhinitis often precedes asthma it is possible that effective treatment of allergic rhinitis may reduce asthma progression. The aim of our study is to investigate history of allergic rhinitis as a risk factor for asthma and the potential effect of allergen immunotherapy in attenuating the incidence of asthma. Hospital-referred non-asthmatic ...
