Asthma is a common chronic inflammatory of airways especially in childhood. Clinical manifestations include coughing, wheezing and sometimes dyspnea. Allergic rhinitis (AR) is a common nasal inflammatory disease in the world. Prevalence of AR is 10-40% in different regions of the world. Clinical manifestations of allergic rhinitis are sneezing, pruritus, congestion and rhino rhea. Etiologies of...
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 : Toxocariasis is a common worldwide zoonotic parasite infection caused by the larvae of Toxocara catti and Toxocara canis. Allergic rhinitis is the most common chronic diseases in the upper respiratory tract. The main symptoms are sneezing, watery rhinorrhea, itching in the nose, eyes and palate. The purpose of this study was to investigate the association between toxocara seropos...
Introduction : Chronic sinusitis is a common cause of attending Otorhinolaryngology clinics. Hence in this study diseases with symptoms similar to chronic sinusitis were evaluated in Booali Hospital during 2009 and 2010. Methods : In this descriptive-analytical cross-sectional survey, 184 nonrandom patients attending Otorhinolaryngology clinics in Booali Hospital during 2009 and 2010 were e...
Background: Chronic sinusitis is one of the most common diseases in childhood that can lead to a lot of complications. Many risk factors are considered to be responsible for the disease. An allergic disorder seems to be one of the most important risk factors. The role of allergic disorders in chronic sinusitis is currently unclear. Also no comprehensive study has been done yet in our country. T...
BACKGROUND Few studies have evaluated the association between delivery by cesarean section (CS) and asthma, allergic rhinitis and chronic rhinitis and whether this association is different in children with and without a family history of asthma. This study aims to investigate whether children born by CS have a higher chance to develop asthma, allergic rhinitis and chronic rhinitis and to evalua...
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: Fungal aeroallergens might sensitize the airway which in turn produces a specific cytokine profile. Objective: To evaluate the IL-25 and IL-33 profile in patients with fungal allergic rhinitis. Methods: The present study examined patients who were evaluated due to allergic rhinitis (AR) at Emam Reza Hospital of Shiraz, Iran. The all...
Chronic rhinitis is a very common disease, as the prevalence in the general population resulted to be 40%. Allergic rhinitis has been considered to be the most frequent form of chronic rhinitis, as non-allergic rhinitis has been estimated to account for 25%. However, several evidences suggested that non-allergic rhinitis have been underrated, especially in children. In pediatrics, the diagnosti...
The term rhinitis implies inflammation of the lining of the nose. Characteristic symptoms are a blocked nose, anterior and posterior rhinorrhea, sneezing and itching. Not all cases of chronic rhinitis have an allergic basis. Chronic non-allergic rhinitis is defined as a condition where ongoing rhinitic symptoms are present for many months (as for persistent allergic rhinitis) but there is no Ig...
