BACKGROUND Inhalation of endotoxin may enhance inflammatory airway response in sensitized asthmatics persons after allergen(s) inhalation. OBJECTIVE To evaluate nasal response to intranasal instillation of Dermatophagoides pteronyssinus (Dp), endotoxin (LPS), and to Dp+LPS in children with perennial allergic rhinitis (PAR). METHODS 10 PAR children (positive skin prick test to Dp) and 10 non...

BACKGROUND Allergy represents a risk factor at the base of sleep-disordered breathing in pediatric age. Among allergic diseases, the atopy is characterized by a tendency to be "hyperallergic." Sleep-disordered breathing is also known in orthodontics as correlated with the morphology of craniofacial complex. The aim of this study was to investigate the relation between atopy and sleep-disordered...

OBJECTIVE To evaluate the outcomes of surgical intervention for empty nose syndrome (ENS). DATA SOURCE Cochrane Collaboration database, U.S National Institutes of Health database (ClinicalTrials), U.S National Library of Medicine (PubMed). REVIEW METHODS Structured search using medical subject-heading terms: nose, turbinate, surgery, atrophic rhinitis, and empty nose syndrome. RESULTS A t...

OBJECTIVE Allergic rhinitis, a disease that impairs quality of life, is characterized by inflammation due to an allergic reaction. Fexofenadine is a second-generation histamine receptor blocker well known for its potent interaction with this inflammatory process. The main aim of this study was to further clarify the anti-inflammatory effects exerted by fexofenadine in patients with intermittent...

BACKGROUND Fencers often complain of progressive difficulty in breathing during matches, which is generally attributed to restricted air, light and heat circulation from wearing a mask. Physiologically, the nasal structure generates airflow resistance that can reach -50% of the total respiratory resistance. OBJECTIVES This study aims to investigate the presence of nasal obstruction in fencers...

Breathing route during sleep has been studied very little, however, it has potential importance in the pathophysiology of sleep disordered breathing. Using overnight polysomnography, with separate nasal and oral thermocouple probes, data were obtained from 41 subjects (snorers and nonsnorers; 25 male and 16 female; aged 20-66 yrs). Awake, upright, inspiratory nasal resistance (Rn) was measured ...

Background. This prospective, controlled, parallel-group observational study investigated the efficacy of a spray containing hyaluronic acid and dexpanthenol to optimise regular treatment after nasal cavity surgery in 49 patients with chronic rhinosinusitis. Methods. The control group received standard therapy. Mucosal regeneration was determined using rhinoscopy sum score (RSS). Pre- and posto...

BACKGROUND Perforations in the nasal septum (NSP) give rise not only to disintegration of the septum anatomy but also impairment in normal nasal physiology. The successes of these surgical techniques are usually equated to anatomical closure of the perforation. The goal of this study is to evaluate the subjective and objective results of our surgical technique for septal perforation surgery. ...

OBJECTIVE To asses the effects of two topical nasal corticosteroids sprays on hyposmia in patients with persistent allergic rhinitis. MATERIAL AND METHODS The study was a prospective clinical trial and it included twenty four patients with persistent allergic rhinitis (PER) and hyposmia (H). The patients were divided into two groups depending on the type of corticosteroid topical nasal spray ...
