BACKGROUND AND OBJECTIVE: Laryngeal lesions are usually investigated by microlaryngoscopy, biopsy, and histopathology. This study aimed to evaluate the combined use of Narrow Band Imaging (NBI) and High-Speed Imaging (HSI) in the differentiation of glottic lesions in awake patients. STUDY DESIGN: Prospective diagnostic study. MATERIALS AND METHODS: Thirty-six awake patients with 41 glottic lesions were investigated with both NBI and HSI, and the suspected diagnoses were compared to the histopathological results of tissue biopsies taken during subsequent microlaryngoscopies...

OBJECTIVE: Endoscopic examination followed by tissue biopsy is the gold standard in the evaluation of lesions of the upper aerodigestive tract. However, it can be difficult to distinguish between healthy mucosa, dysplasia, and invasive carcinoma. Optical coherence tomography (OCT) is a non-invasive technique which acquires high-resolution, cross-sectional images of tissue in vivo. Integrated into a surgical microscope, it allows the intraoperative evaluation of lesions simultaneously with microscopic visualization...

INTRODUCTION: Foreign body aspiration is usually a serious condition that is most common among the pediatric population, and rare in adults. In adults, aspiration may be tolerated for a long time. CASE REPORTS: Our first case is a 38-year-old man who presented with a 2-day history of swallowing a foreign body. He was completely asymptomatic. Chest X-ray revealed the presence of 5-cm foreign object in the right main bronchus. Rigid bronchoscopy was performed and a knife was removed from the right main bronchus...

INTRODUCTION: Dystonia is a disorder of movement caused by various etiologies. Laryngeal dystonia is caused by the spasm of laryngeal muscles. It is a disorder caused by vocal fold movement in which excessive adduction or abduction of the vocal folds occurs during speech. The pathophysiology of this type of dystonia is not fully known. Some researchers have suggested that basal ganglia structures and their connections with cortical areas have been involved in the pathogenesis of dystonia...

For patients with large or recurrent laryngeal cancer, total laryngectomy surgery is usually performed. In the absence of a larynx, tracheoesophageal (TE) voice is the gold standard for alaryngeal phonation. The mechanisms underlying TE voice are unknown, but pharyngoesophageal (PE) segment vibration has been shown to play a key role. The aim of this study was to systematically explore the mechanics of PE segment vibration during TE phonation. A 2D axisymmetric finite-element model with two domains representing the air and PE wall was developed...

In narrow band (NB) laryngeal endoscopy, the clinician usually positions the endoscope near the tissue for a correct inspection of possible vascular pattern alterations, indicative of laryngeal malignancies. The video is usually reviewed many times to refine the diagnosis, resulting in loss of time since the salient frames of the video are mixed with blurred, noisy, and redundant frames caused by the endoscope movements. The aim of this work is to provide to the clinician a unique larynx panorama, obtained through an automatic frame selection strategy to discard non-informative frames...

Exercise-inducible laryngeal obstruction (EILO) has been recognized as a not rare respiratory problem in youth practicing sports. The aim of the study was to test the mechanosensitivity of the larynx, and to identify the factors affecting it in a group of youth with proven EILO. Laryngeal sensory testing was performed in 54 adolescents and young adults with EILO. Laryngeal mucosal alterations were assessed according to the Reflux Finding Score (RFS). The data concerning diseases possibly affecting the upper airway, findings of previously performed flexible videolaryngoscopy during exercise, and RFS score were compared between the participants with laryngeal hyposensitivity and those with normal sensitivity...

Bacterial infection of the laryngeal air sacs (air sacculitis) is infrequently reported in nonhuman primates, where it leads to chronic respiratory disease. It is particularly uncommon in macaques; however, we report here suppurative air sacculitis with extension to adjacent cervical tissues in three rhesus macaques and one Japanese macaque. Staphylococcus aureus, Streptococcus sp., and an anaerobic bacterium were isolated.

Botulinum toxin (Botox) is an exotoxin produced from Clostridium botulinum. It blocks the release of acetylcholine from the cholinergic nerve end plates resulting in inactivity of the muscles or glands innervated. The efficacy of Botox in facial aesthetics is well established; however, recent literature has highlighted its utilization in multiple non-cosmetic medical and surgical conditions. The present article reviews the current evidence pertaining to Botox use in the non-cosmetic head and neck conditions...

CDK8, a member of the transcriptional subtype of the cyclin-dependent kinases (CDKs) family, shows remarkable cancer tissue specific expression profile and rather more selective contribution to the regulation of gene expression levels involved in some signaling pathways. However, the effect of CDK8 on the malignant phenotype of human laryngeal squamous cell carcinoma (LSCC) cells and the potential molecular mechanisms remain unclear. In the present study, we evaluated the expression levels of CDK8 by quantitative real-time reverse-transcriptase polymerase chain reaction (qRT-PCR) and immunohistochemistry in tissue samples of 60 LSCC patients...

Central patterns generators (CPGs) are neural circuits that drive rhythmic motor output without sensory feedback. Vertebrate CPGs are generally believed to operate in a top-down manner in which premotor interneurons activate motor neurons that in turn drive muscles. In contrast, the frog (Xenopus laevis) vocal CPG contains a functionally unexplored neuronal projection from the motor nucleus to the premotor nucleus, indicating a recurrent pathway that may contribute to rhythm generation. In this study we characterized the function of this bottom-up connection...
