1. The Effect of Turbinate Injection of Botulinum Toxin A on the Symptoms of Idiopathic Rhinitis
Abstract Introduction Idiopathic rhinitis is a nonallergic and noninfectious rhinitis characterized mainly by nasal obstruction and rhinorrhea, resulting from an autonomic imbalance. Botulinum toxin type A (BTX-A) demonstrated its action in reducing rhinorrhea and nasal obstruction when injected into the nasal turbinates or septum. Objective To analyze the

2. Inferior Turbinate Reduction during Rhinoplasty: Is There Any Effect on Rhinitis Symptoms?
Abstract Introduction Inferior turbinate surgery is often performed concomitantly with rhinoseptoplasty. As inferior turbinates play a major role in allergic rhinitis, it seems reasonable to suggest that inferior turbinate surgery reduces allergy. Objective To assess the impact of nasal turbinate surgery on non-obstructive allergic symptoms (nasal discharg

3. Are computed tomography 3D measurements of the upper airways in mouth-breathing children in agreement with the ENT clinical diagnosis of obstruction?
Resumo Introdução: O exame clínico otorrinolaringológico da via aérea superior tem sido historicamente feito com a ajuda de imagens radiográficas para diagnosticar causas obstrutivas da respiração bucal. Objetivo: O objetivo deste estudo foi comparar as medidas volumétricas em 3D da cavidade nasal, nasofaringe e orofaringe entre crianças com resp

4. Angioleiomyoma of the Nasal Cavity
Introduction Vascular leiomyoma of the nasal cavity is an extremely rare tumor that represents less than 1% of all vascular leiomyomas. It is more prevalent in women between the fourth and sixth decades, reaching primarily the inferior nasal turbinates. Objectives Reporting and assisting the systematization of more accurate diagnostic methods in clinical

5. Olfactory neuroepithelium in the superior and middle turbinates: which is the optimal biopsy site?
INTRODUCTION: Olfactory neuroepithelium (ON) biopsy has several therapeutic applications for both disorders of olfaction and neurodegenerative diseases. Successful collection of ON is still anything but routine due to a dearth of studies on the distribution of ON in the superior and middle turbinates. AIM: To determine the location in which ON is most likely

6. Dimensões internas nasais de adultos com obstrução nasal avaliadas por rinometria acústica / Internal nasal dimensions of adults with nasal obstruction assessed by acoustic rhinometry
Objetivo: Caracterizar a geometria nasal de adultos com obstrução nasal (ON) decorrente de desvio septal (DS) e/ou hipertrofia de conchas (HC) pela análise de áreas seccionais e volumes de segmentos específicos da cavidade nasal por rinometria acústica. Modelo: Estudo prospectivo. Local de Execução: Laboratório de Fisiologia, HRAC-USP e Ambulatório

7. Efeitos da rinosseptoplastia sobre as dimensões internas nasais e ressonância da fala em indivíduos com fissura de lábio e palato unilateral reparada: análise por rinometria acústica e nasometria / Effects of rhinoseptoplasty on the internal nasal dimensions and speech resonance in individuals with repaired unilateral cleft lip and palate: assessment by acoustic rhinometry and nasometry
Objective: To analyze the effects of rhinoseptoplasty on the nasal cross-sectional areas and volumes, and the speech nasalance of individuals with repaired unilateral cleft lip and palate, assessed by acoustic rhinometry and nasometry. Design: Prospective analysis. Setting: Surgery Service and Laboratory of Physiology at the Hospital for Rehabilitation of Cr

8. Ação do estrógeno e progesterona na mucosa nasal humana: avaliação do transporte mucociliar nasal de sacarina e pesquisa de receptores hormonais através de método imuno-histoquímico / Estrogen and progesterone influence in human nasal mucosa: evaluation of nasal saccharin mucociliary transport and test for hormone receptors with immunohistochemical staining
Although nasal mucociliary clearance has been thoroughly studied, there is controversial evidence that it is directly influenced by female sex hormones. This study focused on: 1. evaluating saccharin nasal mucociliary transport in both sexes and during the follicular, periovulatory and luteal phases of consecutive ovarian cycles, and 2. identifying the expre

9. In vivo inhibition of respiratory syncytial virus by ribavirin.
Ribavirin reduced the amount of respiratory syncytial virus in nasal turbinates and lung tissues of experimentally infected cotton rats by over 90%. An effect was seen when the drug was given either intraperitoneally or by aerosol; however, the antiviral effect was achieved at much lower doses when delivered by the aerosol route. No animal deaths due to the

10. Severe Acute Respiratory Syndrome Coronavirus Infection of Golden Syrian Hamsters
Small animal models are needed in order to evaluate the efficacy of candidate vaccines and antivirals directed against the severe acute respiratory syndrome coronavirus (SARS CoV). We investigated the ability of SARS CoV to infect 5-week-old Golden Syrian hamsters. When administered intranasally, SARS CoV replicates to high titers in the lungs and nasal turb

11. Pulmonary Clearance of Bacillus subtilis Spores in Pigs
The pulmonary clearance rate of Bacillus subtilis was determined in ten pigs (23-39 kg) exposed simultaneously for 15 minutes to an aerosol generated by an ultrasonic nebulizer. Two pigs were killed at each interval of zero, two, four, eight and 12 hours and the concentrations of B. subtilis in lungs (all lobes), dorsal and ventral nasal turbinates, trachea,

12. Control of nasal vasculature and airflow resistance in the dog.
Nasal vascular and airflow resistances have been measured in dogs, simultaneously on both sides separately. Vascular resistance was measured either by constant flow perfusion of the terminal branch of the maxillary artery (which supplies, via the sphenopalatine artery, the nasal septum, most of the turbinates and the nasal sinuses) or by measuring blood flow
