INTRODUCTION Laryngotracheobronchitis is a rare, but in severe cases may lead to laryngeal edema progressing to complete closure of the subglottis within a few hours, without prompt treatment. CASE PRESENTATION We present the case of acute airway obstruction caused by laryngotracheobronchitis in a 6-year-old boy, initially misdiagnosed and treated as foreign body aspiration. The treatment of ...

Elderly patients present deterioration in voice quality due to anatomical and functional changes of the larynx associated with the aging process, and other voice disorders common in the elderly population. Identified causes of geriatric voice dysfunction include anatomic changes in the larynx such as vocal fold atrophy, central neurologic conditions (e.g. stroke, Parkinson’s disease, essential ...

Introduction The indirect laryngoscopy has an important role in the characterization of reflux laryngitis. Although many findings are nonspecific, some strongly suggest that the inflammation is the cause of reflux. Objective The aim of this study was to evaluate the correlation between reflux symptoms and the findings of indirect laryngoscopy. Methods We evaluated 27 patients with symptoms of p...

INTRODUCTION Radionecrosis (post-radiotherapy laryngeal submucosal inflammation and necrosis) is a complication of (chemo) radiotherapy for hypopharyngeal cancer that is difficult to differentiate from tumor recurrence. CASE PRESENTATION A 67-year-old Japanese man presented with a condition extremely difficult to diagnose differentially as radionecrosis or tumor recurrence after radiotherapy ...

Anaphylactic shock is an unexpected, sudden and sometimes deadly event that attacks the patient in 75% of the cases without pre-existent history of allergy. In general, drugs, hymenopteric poisons and nutrients (according to the recent concept) are responsible. Beside the classical IgE-mediated anaphylactic shock there exists another anaphylactic shock, identical in its clinical picture and tre...

PURPOSE Anaphylactic shock is sometimes accompanied by local interstitial edema due to increased vascular permeability. We performed magnetic resonance imaging (MRI) to compare edema in the larynx and brain of anesthetized rats during anaphylactic hypotension versus vasodilator-induced hypotension. METHODS Male Sprague Dawley rats were subjected to hypotension induced by the ovalbumin antigen...
