  • Laryngitis from Reflux: Prevention for the Performing Singer
    Laryngitis from Reflux: Prevention for the Performing Singer David G. Hanson, MD, FACS Jack J. Jiang, MD, PhD Laryngitis in General Laryngitis is the bane of performers and other professionals who depend on their voice for their art and livelihood. Almost every person has experienced acute laryngitis, usually associated with a viral upper- respiratory infection. Whenever there is inflammation of the vocal fold epithelium, there is an effect on voice quality and strength. Therefore, it is important to understand the factors that can cause laryngitis, especially the preventable causes of laryngitis. Laryngitis is a generic term for inflammation or irritation of the laryngeal tissues. The inflammation can be caused by any kind of injury, including infection, smoking, contact with caustic or acidic substance, allergic reaction, or direct trauma. Inflammatory response of the tissues includes leakage of fluid from blood vessels with edema or swelling, congregation of white blood cells, which release mediators of inflammation, and engorgement of the blood vessels. Most commonly laryngitis occurs from viral infection of the laryngeal epithelial lining associated with a typical cold. The viral infection is almost always quickly conquered by the body's immune system and lasts at most a few days. This kind of acute laryngitis rarely causes any long-term problem unless the vocal folds are damaged by overuse during the illness. Examination of the larynx will show whether the vocal folds are inflamed and allows some prediction of the degree of risk for damage. Other infections of the larynx are fortunately not common but include infections with bacteria and other organisms.

  • Swallowing in Patients with Laryngitis
    AG-2017-86 AHEADORIGINAL OF ARTICLEPRINT dx.doi.org/10.1590/S0004-2803.201800000-10 Swallowing in patients with laryngitis Isabela MODA, Hilton Marcos Alves RICZ, Lilian Neto AGUIAR-RICZ and Roberto Oliveira DANTAS Received 21/8/2017 Accepted 5/10/2017 ABSTRACT – Background – Dysphagia is described as a complaint in 32% of patients with laryngitis. Objective – The objective of this investigation was to evaluate oral and pharyngeal transit of patients with laryngitis, with the hypothesis that alteration in oral-pharyngeal bolus transit may be involved with dysphagia. Methods – Videofluoroscopic evaluation of the swallowing of liquid, paste and solid boluses was performed in 21 patients with laryngitis, 10 of them with dysphagia, and 21 normal volunteers of the same age and sex. Two swallows of 5 mL liquid bolus, two swallows of 5 mL paste bolus and two swallows of a solid bolus were evaluated in a random sequence. The liquid bolus was 100% liquid barium sulfate and the paste bolus was prepared with 50 mL of liquid barium and 4 g of food thickener (starch and maltodextrin). The solid bolus was a soft 2.2 g cookie coated with liquid barium. Durations of oral preparation, oral transit, pharyngeal transit, pharyngeal clearance, upper esophageal sphincter opening, hyoid movement and oral-pharyngeal transit were measured. All patients performed 24-hour distal esophageal pH evaluation previous to videofluoroscopy. Results – The evaluation of 24-hour distal esophageal pH showed abnormal gastroesophageal acid reflux in 10 patients. Patients showed longer oral preparation for paste bolus and a faster oral transit time for solid bolus than normal volunteers.

Etiology, epidemiology, pathogenesis and clinical picture Abstract In about 3% of children, viral infections of the airways that develop in early childhood lead to narrowing of the laryngeal lumen in the subglottic region resulting in symptoms such as hoarseness, a barking cough, stridor, and dyspnea. These infections may eventually cause respiratory failure. The disease is often called acute subglottic laryngitis (ASL). Terms such as pseudocroup, croup syndrome, acute obstructive laryngitis and spasmodic croup are used interchangeably when referencing this disease. Although the differential diagnosis should include other rare diseases such as epiglottitis, diphtheria, fibrinous laryngitis and bacterial tracheobronchitis, the diagnosis of ASL should always be made on the basis of clinical criteria. Key words: subglottic laryngitis, croup, laryngeal obstruction, inspiratory dyspnoea, stridor Adv Respir Med. 2019; 87: 308–316 Definition and nomenclature have in common is laryngitis.

  • Common Problems That Can Affect Your Voice It May Come As a Surprise to You the Variety of Medical Conditions That Can Lead to Voice Problems
    Eastern Connecticut Ear, Nose & Throat, P.C. Patient Information 1 Common Problems That Can Affect Your Voice It may come as a surprise to you the variety of medical conditions that can lead to voice problems. The most common causes of hoarseness and vocal difficulties are outlined below. If you become hoarse frequently or notice voice change for an extended period of time, please see your Otolaryngologist (Ear, Nose, and Throat doctor) for an evaluation. ACUTE LARYNGITIS Acute laryngitis is the most common cause of hoarseness and voice loss that starts suddenly. Most cases of acute laryngitis are caused by a viral infection that leads to swelling of the vocal cords. When the vocal cords swell, they vibrate differently, leading to hoarseness. The best treatment for this condition is to stay well hydrated and to rest or reduce your voice use. Serious injury to the vocal cords can result from strenuous voice use during an episode of acute laryngitis. Since most acute laryngitis is caused by a virus, antibiotics are not effective. Bacterial infections of the larynx are much rarer and often are associated with difficulty breathing. Any problems breathing during an illness warrants emergency evaluation. CHRONIC LARYNGITIS Chronic laryngitis is a non-specific term and an underlying cause should be identified. Chronic laryngitis can be caused by acid reflux disease, by exposure to irritating substances such as smoke, and by low grade infections such as yeast infections of the vocal cords in people using inhalers for asthma. Chemotherapy patients or others whose immune system is not working well can get these infections too.

  • On Croup: Its Nature, and Treatment
    iSrit.] NATURE AND TREATMENT OF CROUP. 61! d Article VI.- On Croup: Its Nature, and Treatment. By John \y Mom, L.Il.C.P. Edin., etc.; District Medical Officer, West Ham Union, London. (Continued from page 517.) The general absence of ulceration distinguishes both croup and diphtheria from cynanche maligna, or putrid or ulcerative sore- throat, the angina maligna of Fothergill and the old authors. But they may be found in conjunction with it, or with one another, in- creasing the danger to be apprehended from one alone. Dr Ewing Whittle of Liverpool divides croup-like affections into seven :? 1 st, Cynanche trachealis of Cullen, true croup, with the forma- tion of false membrane, the croup we are here considering, and sup- posed by some, as we have seen, to be always diphtheria; but as We have shown this is not really so, but an allied and distinct disease. 2d} Angina stridula of Bretonneau, pseudo-croup of Guersant, the acute asthma of Miller, characterized by remissions not usual in croup, inflammatory to a very great extent, but without forma- tion of false membrane. 3clj Croup complicated with diphtheria, diphtheritic croup. 4tli, Sympathetic croup occurring in exanthemata, disappearing when the eruption comes out. This was once observed by the Writer in a case of measles in Edinburgh in 18G4. 5th, Croup caused by an ulcerated condition of the larynx, either following the ulcerated sore-throat of scarlatina or variola, or syphilitic (as in a case of tlie late Dr Gregory of Edinburgh).
