objective(s): asthma results from the interaction between genetic and environmental factors. adam33 gene on chromosome 20p13 is associated with asthma and airway hyperresponsiveness. materials and methods: this is a case-control study, where four snps s1 (rs3918396), t1 (rs2280091), t2 (rs2280090), v4 (rs2787094) of adam33 gene have been assessed in patients with allergic asthma and normal cont...

methyl methacrylate (mma), a widely used monomer in dentistry and medicine has been reported to cause abnormalities or lesions in several organs. experimental and clinical studies have documented that monomers may cause a wide range of adverse health effects such as irritation to skin, eyes, and mucous membranes, allergic dermatitis, stomatitis, asthma, neuropathy, disturbances of the central n...

background: allergic rhinitis (ar) is an allergic disorder of the nasal tissue that underlies diseases such as sinusitis, otits and asthma. different predisposing factors including immunological and non-immunological factors contribute to the disease pathogenesis. objective: to investigate association of haptoglobin (hp) phenotypes (hp1-1, 2-1 and 2-2) with serum immunoglobulins a and e levels ...

background: allergic rhinitis (ar) represents a global health problem, affecting 5-50% of the population worldwide and numerous classes of pharmacological agents are available for its treatment. two more popular of these drugs are loratadine and cetirizine. there are few direct comparator studies between these two drugs with inconsistent results. m aterials and methods: a randomized, double-bli...

abstract 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 often lead to rhinit...

Introduction: This study evaluated the effect of gelfoam impregnated with botulinum toxin on the symptoms induced by allergic rhinitis. Materials and Methods: In total, 30 patients with allergic rhinitis who did not respond to common therapies were included in this clinical trial study. All patients were treated with intranasal gelfoam impregnated with botulinum toxin type a (...

Background and Aims: Allergic disorders such as asthma, urticaria, eczema, and allergic rhinitis are common worldwide, and allergens are the most common etiology and exacerbating factors. So, This study aimed to find the allergens in these patients with skin prick tests. Materials and Methods: All the allergic cases referred to an allergic clinic in the north of Iran were visited by an allergi...

Allergic rhinitis (AR) is the most prevalent atopic disease in the world, affecting 10-20% of the population or up to 600 million people (Asher et al. 2006; Meltzer and Bukstein 2011). Data from multi-year international studies show that the incidence of upper airway allergy is greater than that for asthma, and since 1994 the prevalence of AR has increased more rapidly than allergic asthma (Ash...

Introduction: Chronic rhinosinusitis (CRS) is a multifactorial disease. Allergies are considered a predisposing factor to CRS; however, this remains controversial. The objective of this research was to investigate the prevalence of co-morbidities and allergic reaction, and to specify the most common allergens in patients with confirmed CRS.   Materials and Methods: One hundred patients with sig...

Background Allergic rhinitis (AR) is a common form of nose inflammatory disease that occurs when the mucosal immune system overreacts to environmental allergens especially in the air. It’s absolutely clear that the prevalence of AR varies between different countries, and even between the various areas of a country. The purpose of present investigation is to determine the prevalence of AR, as mo...
