1. Validation of a classification and scoring system for the diagnosis of laryngeal and pharyngeal squamous cell carcinomas by confocal laser endomicroscopy
Abstract Introduction: Confocal laser endomicroscopy is an optical imaging technique that allows in vivo, real-time, microscope-like images of the upper aerodigestive tract’s mucosa. The assessment of morphological tissue characteristics for the correct differentiation between healthy and malignant suspected mucosa requires strict evaluation criteria. Ob

2. The role of intraoperative narrow-band imaging in transoral laser microsurgery for early and moderately advanced glottic cancer
Resumo Introdução: A microcirurgia transoral a laser é uma técnica bem estabelecida para o tratamento de câncer de laringe inicial e moderadamente avançado. Objetivo: Verificar a utilidade da imagem de banda estreita na avaliação intraoperatória da mucosa laríngea na especificação das margens cirúrgicas. Método: Foram avaliados 44 cânceres

3. Adult Rhabdomyoma of the Larynx
Introduction Rhabdomyoma is a rare benign tumor derived from skeletal muscles. Laryngeal rhabdomyomas are even rarer, with only approximately 40 reported cases in world literature. Laryngeal rhabdomyomas usually are seen as masses covered by mucosa. They are often solitary asymptomatic tumors, but symptoms such as hoarseness can occur. The radiologic fea

4. Análise comparativa da amplitude de vibração das pregas vocais e do coeficiente de contato durante a emissão da vogal /ɛ/ prolongada e vibração sonorizada de lábios e língua / Comparative analysis of the amplitude of vibration of the vocal folds and the coefficient of contact during the utterance of the sustained vowel / ? / and the lips and tongue trills
Exercises of audible vibration are widely used for the treatment of dysphonia and vocal preparation of professional voice users. There is little research done studying vocal physiology during exercise. The aim of this study is to compare the differences in cordal vibration during the exercises of lips and tongue trills and the sustained vowel / ? / as to the

5. Distribuição das fibras colágenas e do sistema de fibras elásticas na camada superficial da lâmina própria da prega vocal com edema de Reinke / Distribution of collagen fibers and elastic system fibers in the superficial layer of the lamina propria of the vocal fold with Reinkes edema
The physiopathological mechanisms underlying Reinkes edema are still unknown and few studies addressed alterations in the fibrillar proteins, collagen and elastin, in extracellular matrix with Reinkes edema. This study was idealized to describe the distribution of collagen fibers and elastic system fibers in Reinkes space with Reinkes edema, comparing with n

6. Relação entre achados videonasolaringoscópicos e ph-metria esofágica de 24 horas em crianças com manifestações clínicas de refluxo extra-esofágico
INTRODUCTION: gastroesophageal reflux is considered contributing factor on otolaryngology and respiratory diseases, mainly in children, that are not responsive to the usual therapies. The aim of this study was to compare the results of the flexible nasopharyngolaryngoscope with conventional 24hours esophageal pH probe monitoring of children with respiratory

7. Análise da voz e do comportamento do trato vocal suplaglótico por meio visual, perceptivo-auditivo e acústico em mulheres disfônicas com diferentes configurações glóticas / Analysis of voice and supraglottic vocal behavior using visual, perceptual and acoustic methods in dysphonic women whith different glottic configurations
Objective: To analyze voice and supraglottic vocal tract using imaging of the vocal tract, perceptual and acoustic methods in dysphonic women with different glottic configurations. Method: The studied sample comprised 31 women, aged 20 to 45 years, with vocal complaints and affections. Subjects underwent brief assessment of sensorial-motor-oral system, video

8. Alterations in the laryngeal mucosa after exposure to asbestos.
The laryngeal mucosa of 195 workers in an asbestos cement factory (Salonit Anhovo, Yugoslavia) and in a control group was examined. The factory manufactures asbestos cement products containing about 13% of asbestos (8% amosite, 12% crocidolite, and 80% chrysotile) of different provenance. Alterations in the laryngeal mucosa were more frequent in the factory

10. Afferent pathway(s) for pharyngeal dilator reflex to negative pressure in man: a study using upper airway anaesthesia.
1. To determine the afferent pathways mediating pharyngeal dilator muscle activation in response to negative airway pressure in man, we recorded genioglossus electromyogram (EMG) activity (via intra-oral bipolar surface electrodes) in response to 500 ms duration pressure stimuli of -15 and -25 cm H2O in normal, conscious, supine subjects relaxed at end-expir

11. Role of Bordetella pertussis Virulence Factors in Adherence to Epithelial Cell Lines Derived from the Human Respiratory Tract
During colonization of the respiratory tract by Bordetella pertussis, virulence factors contribute to adherence of the bacterium to the respiratory tract epithelium. In the present study, we examined the roles of the virulence factors filamentous hemagglutinin (FHA), fimbriae, pertactin (Prn), and pertussis toxin (PT) in the adherence of B. pertussis to cell

12. Mycobacterium avium Infection of Epithelial Cells Results in Inhibition or Delay in the Release of Interleukin-8 and RANTES
Mycobacterium avium is an opportunistic pathogen in AIDS patients, who acquire the infection mainly through the gastrointestinal tract. Previous studies in vitro have shown that M. avium invades epithelial cells of both intestinal and laryngeal origin. In addition, M. avium enters the intestinal mucosa of healthy mice. Because M. avium invasion of the intest
