the aim of current study is to describe clinical similarities and differences between atopic and non-atopic asthma in children. in a cross-sectional study, 95 asthmatic children (75 allergics and 20 nonallergics) were included in the study. demographic, clinical, and familial history were compared between two groups. there was no significant differences between variables like sex, age of onset ...

Iran is the main producer of Saffron in the world and a great number of Khorasan (the largest province of Iran) are involved in growing this plant. Recently, saffron pollen has found great importance due to inducing allergic reactions. In this study, the prevalence and clinical symptoms of saffron pollen allergy and specific IgE level in saffron workers have been studied. For this purpose, 167 ...

atopic dermatitis (ad) is a heterogeneous disease with regard to clinical phenotype and natural history. we investigated t cell subtypes and cytokine responses in peripheral blood and skin lesions of ad patients with various sensitivities. immunological studies were performed in 27 subjects: 9 house dust mite (hdm)-sensitized; 6 subjects with sensitizations other than hdm; 7 non-allergic ad pat...

UNLABELLED Self-reported non-allergic nasal symptom triggers in non-allergic ('vasomotor') rhinitis overlap with commonly identified environmental exposures in non-specific building-related illness. These include extremes of temperature and humidity, cleaning products, fragrances, and tobacco smoke. Some individuals with allergic rhinitis also report non-allergic triggers. We wished to explore ...

Background: Rhinitis is a prevalent chronic inflammatory disease of the nasal mucosa. Arachidonic acid-derived lipoxin A4 (LXA4) has long been recognized to exert crucial anti-inflammatory and pro-resolving effects on inflammatory responses through a specific receptor named formyl peptide receptor-2 (FPR2). This study aimed to determine the serum level of LXA4 as well as the relative mRNA expre...

background: allergic fungal sinusitis is a non-invasive disease, and accounts for approximately 6-8% of all chronic sinusitis requiring surgical intervention. as the treatment and prognosis of these disorders vary significantly, it is extremely important to recognize allergic fugal sinusitis and differentiate it from chronic sinusitis of bacterial and fungal origin. this prospective study evalu...

RHINITIS IS A GLOBAL PROBLEM AND IS DEFINED AS THE PRESENCE OF AT LEAST ONE OF THE FOLLOWING: congestion, rhinorrhea, sneezing, nasal itching, and nasal obstruction. The two major classifications are allergic and nonallergic rhinitis (NAR). Allergic rhinitis occurs when an allergen is the trigger for the nasal symptoms. NAR is when obstruction and rhinorrhea occurs in relation to nonallergic, n...
