the first epidemiologic survey of childhood allergic rhinitis in iran was carried out from may 1995 until april 1996.. a questionnaire was distributed among 4584, 11-15 year-old children of both sexes, to be completed under supervision of medical students. nasal smears were collected from the cases with allergic rhinitis (n = 445, 5.8%.), and from 340 healthy children for comparison. significan...

Tuning the charge carier concentration of graphene is one key challenges in field research. An effective solution for this to dope by organic molecules that physisorb or self-assemble on surface. Therefore, a comprehensive understanding their surface structures at molecular level realy nessesary. In contribution, we report role applied electrode potential adsorption/self-assembly such n-dope mo...

background and objectives: nasal polyposis is a diseases resulting from complex pathogenetic mechanisms. some studies showed that tgfβ1 had significant role in this pathogenesis. in this study, we investigated the roe of cytokines and mediators in polyp development. material and methods: in this case- control study, healthy nasal mucosal samples were obtained from 24 people undergoing septoplas...

abstract facial defects not only impact on the function and quality of life but also affect the psychological well-being and social behavior of patients. a nasal prosthesis can re-establish the esthetics and anatomical contour in patients with mid-facial defects, often more effectively than surgical reconstruction. for successful results, many factors such as retention, texture, color match and...

This study represents an unusual case of mucormycosis localized in nasal cavity of a German shepherd dog. The patient was a 1-year-old male guard dog with unilateral nasal epistaxis, mucopurulent nasal discharge, sneezing and nose pawing. The dog had a history of head trauma about 2 months before admission, which was associated with mild self-limited epistaxis. Initial nasal rhinoscopy showed s...

background: nasal intermittent positive pressure ventilation (nippv) is a non-invasive ventilatory mode, which delivers mechanical ventilation via nasal tubes or prongs. the present study was conducted to compare the efficacy of nippv and nasal continuous positive airway pressure ventilation (ncpap) in reducing the need for intubation in preterm infants with respiratory distress syndrome (rds)....

introduction: environmental fungi, molds and yeasts, can infest the nasal cavity through inhaled air. there is some evidence that they could be the main cause of chronic rhinosinusitis (crs) but little is known about the normal fungal flora in the human nose. the objective of this study was to assess the normal fungal flora of the nasal mucus in adults in kerman. materials and methods: we condu...
