Monosodium benzoate hypersensitivity in subjects with persistent rhinitis
2004
Background: Very few data are available from the literature on whether nonatopic subjects affected by persistent rhinitis may show the appearance of objective symptoms of rhinitis after the ingestion of food additives such as tartrazine (E102), erythrosine (E127), monosodium benzoate (E211), p-hydroxybenzoate (E218), sodium metabisulphite (E223), and monosodium glutamate (E620). It is still unclear whether the ingestion of food additive may cause, as well, a consensual reduction of nasal peak inspiratory flow (NPIFR). Therefore, we used a double-blind placebo-controlled (DBPC) study to evaluate this hypothesis. Patients and methods: Two hundred and twenty-six consecutive patients (76 male…
Radiofrequency volumetric tissue reduction (RFVTR) of inferior turbinates: a new method in the treatment of chronic nasal obstruction.
2001
Twenty-two Caucasians (16 male and 6 female) with chronic bilateral nasal obstruction due to hypertrophic inferior turbinates were followed up over a three-month period. They were assessed by clinical examination, as active anterior rhinometry, and acoustic rhinometry before and after topical decongestion, preoperatively and three months after surgery. All patients were treated by application of radiofrequency-volumetric-tissue reduction (RFVTR, or somnoplasty) to both inferior turbinates. Initial postoperative edematous response disappeared during the first week after RFVTR. Three months postoperatively 20 of 22 patients (91%) reported subjective improvement of nasal patency. The average …
Clinical Assessment of Nasal Airway Obstruction
2019
For the evaluation of nasal airway obstruction physical examination, anterior rhinoscopy, laboratory workup, imaging studies, and rhinomanometric studies may be required. Laboratory workup may consist of counts of neutrophil investigating infectious diseases, eosinophil for allergy-related disorders, and mast cell in food allergy. Imaging workup contains computed tomography (CT) and magnetic resonance imaging. Physically based studies involve rhinomanometry and acoustic rhinometry techniques. Nasal resistance is responsible for more than 50% of the resistance of the total airway. Nasal resistance is made up of two layers: the deeper layer consists of underlying bone, cartilage, and muscle, …
