2. Nasal Polyposis: More than a Chronic Inflammatory Disorder-A Disease of Mechanical Dysfunction- The São Paulo Position
Abstract Introduction The importance of our study lies in the fact that we have demonstrated the occurrence ofmechanical dysfunction within polypoid tissues, which promotes the development of polyps in the nasal cavity. Objective To change the paradigm of nasal polyposis (NP). In this new conception, the chronic nasal inflammatory process that occurs in

3. Investigation on the nasal airflow characteristics of anterior nasal cavity stenosis
We used a computational fluid dynamics (CFD) model to study the inspiratory airflow profiles of patients with anterior nasal cavity stenosis who underwent curative surgery, by comparing pre- and postoperative airflow characteristics. Twenty patients with severe anterior nasal cavity stenosis, including one case of bilateral stenosis, underwent computed tomog

4. The effects of smoking and smoking cessation on nasal mucociliary clearance, mucus properties and inflammation
OBJECTIVE: The aim of the present study was to assess nasal mucociliary clearance, mucus properties and inflammation in smokers and subjects enrolled in a Smoking Cessation Program (referred to as quitters). METHOD: A total of 33 subjects with a median (IQR) smoking history of 34 (20-58) pack years were examined for nasal mucociliary clearance using a sacc

5. Molecular characterization of Brazilian equid herpesvirus type 1 strains based on neuropathogenicity markers
Partial nucleotide sequences of ORF72 (glycoprotein D, gD), ORF64 (infected cell protein 4, ICP4) and ORF30 (DNA polymerase) genes were compared with corresponding sequences of EHV-1 reference strains to characterize the molecular variability of Brazilian strains. Virus isolation assays were applied to 74 samples including visceral tissue, total blood, cereb

6. pH in exhaled breath condensate and nasal lavage as a biomarker of air pollution-related inflammation in street traffic-controllers and office-workers
OBJECTIVE: To utilize low-cost and simple methods to assess airway and lung inflammation biomarkers related to air pollution. METHODS: A total of 87 male, non-smoking, healthy subjects working as street traffic-controllers or office-workers were examined to determine carbon monoxide in exhaled breath and to measure the pH in nasal lavage fluid and exhaled

7. Quantificação nefelométrica da proteína beta-trace para o diagnóstico da fístula liquórica da base anterior do crânio : determinação do valor de corte em fluídos nasais utilizando dois grupos controles / Predictability of quantification of beta-trace protein for diagnosis of cerebrospinal fluid leak : cut off determination in nasal fluids with two control groups
Introdução: A Fístula liquórica da base anterior do crânio é a comunicação anormal entre a cavidade nasal ou os seios paranasais e o espaço subaracnóideo. Sua presença aumenta a incidência de complicações, como principalmente a meningite, com riscos de morte ou de seqüelas, como surdez, déficits motores e cognitivos. O diagnóstico precoce e

8. AnÃlise do perfil de citocinas no fluido de lavado nasal de crianÃas com rinite alÃrgica e alteraÃÃes clÃnicas apÃs tratamento com mometasona, montelucaste ou desloratadina
Allergic rhinitis (AR) represents a global health problem and its prevalence has increased in the last years. The aim of this study is to evaluate the cytokine profile in nasal lavage fluid and the clinical alterations in children with AR after different drugs treatment. This is a prospective randomized open study; twenty-eight children aged from six to twel

10. Estudo da inibição do oxido nitrico sobre funções de eosinofilos humanos estimulados com eotaxina e RANTES in vitro / Study of nitric oxide inhibition in human eosinophil functions stimulated in vitro with eotaxin and RANTES
Eosinophils participate in the pathogenesis of many inflammatory diseases, including parasitic infections and allergic diseases. Of the allergic diseases, asthma is characterized by eosinophilia. Currently, asthma affects 300 million people in world, and is an important public health problem. Asthma is an inflammatory chronic disease that involves interactio

11. Acute effects of continuous positive airway pressure on mucociliary clearance of healthy subjects: the impact of humidification and air leak / Efeitos agudos da pressão positiva contínua de vias aéreas (CPAP) e impacto da umidificação e vazamento aéreo sobre o transporte mucociliar e inflamação nasal de indivíduos sadios
Continuous positive airway pressure (CPAP) is the treatment of choice for patients with Obstructive Sleep Apnea but yet nasal symptoms are often reported. Air leaks and changes of the respiratory epithelium are important in the development of nasal symptoms and heated humidification is used to alleviate these symptoms. The aim of this study was to investigat
