Iron Pill-Induced Chemical Laryngitis.

OBJECTIVE: To discuss the presentation and management of pill-induced chemical laryngitis by illustrating a rare case. METHODS: We report a unique case of a patient with iron pill-induced laryngitis. RESULTS: A 71-year-old male presented for evaluation of dysphonia. Five weeks prior, the patient had reportedly aspirated an iron pill. The pill was lodged in his throat for several hours before being coughed up, soft but still intact. Since that event, the patient noted complete voice loss and in clinic was found to have a very breathy and asthenic voice. Stroboscopy revealed aperiodicity with severe false fold compression and significant ulceration of the infraglottic region associated with thick exudate. Vocal folds were mobile but atrophic, with overlying crusted secretions. A sensory deficit was suspected based on scope tolerance. The patient was treated with nebulized ciprodex and humidified air with some improvement in mucosal crusting but had persistent glottic insufficiency and dysphonia, prompting bilateral hyaluronic acid injection. CONCLUSIONS: Pill-induced laryngitis is an extremely rare phenomenon. While typically associated with bisphosphonates, this condition should be considered in any patient presenting with dysphonia and history of aspiration of a pill, including iron supplements. Regardless of the inciting medication, pill-induced laryngitis may be treated with humidified air, nebulized steroids, and antibiotics. Injection augmentation of the vocal folds may be made considered when glottic insufficiency and weak cough contribute to the presentation.

Factors Associated With Infectious Laryngitis: A Retrospective Review of 15 Cases.

OBJECTIVES: To identify the culturable microbes associated with infectious laryngitis and outline effective treatment strategies. METHODS: This is a retrospective chart review of adult patients with persistent dysphonia plus evidence of laryngeal inflammation who underwent biopsy for culture at a tertiary care medical center. Demographic factors, symptoms as reported on validated patient assessment tools, past medical history, social history, culture results, and treatment duration and response were reviewed. RESULTS: Fifteen patients with infectious laryngitis were included in this study. Culture results demonstrated Methicillin-sensitive Staphylococcus aureus (MSSA), Methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, Serratia marcescens, and "normal respiratory flora." In most patients, multiple courses of prolonged antibiotics were needed to treat MSSA or MRSA. Infections associated with other microbes resolved with a single course of antibiotics. CONCLUSIONS: In this population, infectious laryngitis is defined as colonization with bacteria not found in the previously characterized laryngeal microbiome of benign vocal fold lesions. In suspected cases of infectious laryngitis, culture is recommended, by biopsy if needed. For MSSA- and MRSA-associated laryngitis, an extended course of antibiotics may be necessary for symptom improvement and resolution of laryngeal inflammation. However, the optimal treatment regimen has yet to be defined and will require larger, prospective studies.

Laryngotracheal mucormycosis: Report of a case.

Airway mucormycosis is a deadly opportunistic infection that affects immunocompromised persons, particularly diabetics and those undergoing chemotherapy. Although it is typically a pulmonary or sinonasal infection, mucormycosis can affect the larynx and trachea, with devastating results. We report the case of a 46-year-old man with human immunodeficiency virus infection, hepatitis C infection, neurosyphilis, and recently diagnosed Burkitt lymphoma who presented with dysphonia and stridor after receiving one dose of intrathecal chemotherapy. Flexible laryngoscopy detected the presence of fibrinous material that was obstructing nearly the entire glottis. Surgical debridement revealed a firm mucosal attachment; there was little bleeding when it was removed. After debridement, the patient's dyspnea improved only to recur 2 days later. After an awake tracheotomy, laryngoscopy and bronchoscopy identified necrosis extending from the supraglottic area to the carina tracheae. Biopsies demonstrated hyphal architecture consistent with mucormycosis. Despite continued debridements, the fibrinous material reaccumulated. The patient was placed in hospice care; his airway remained patent, but he died from other causes several weeks after presentation. The management of airway mucormycosis is challenging and complex. Fungal airway infections should be considered in the differential diagnosis of an immunosuppressed patient who presents with dyspnea, dysphonia, and vocal fold immobility. Timely diagnosis and management are critical for a successful outcome, although the prognosis is poor if the infection is widespread, even with the best of efforts.

[Staphylococcal tracheitis and toxic shock syndrome in a child]. / Laryngotrachéite à staphylocoque doré compliquée d'un syndrome de choc toxique.

Bacterial tracheitis should be raised as a possible cause in cases of severe febrile dyspnea. It can be life-threatening due to airway obstruction or, less frequently, due to toxic shock syndrome. We report the observation of toxic shock syndrome-complicated bacterial tracheitis in a 14-year-old boy. We describe the signs and symptoms of these conditions as well as the principles of treatment.

Predictors of outcome in an open label, therapeutic trial of high-dose omeprazole in laryngitis.

BACKGROUND: Gastroesophageal reflux is implicated in some cases of laryngitis. There are no established predictors of response to acid suppression therapy in suspected reflux laryngitis. AIM: In a population with laryngitis, the aim is to determine whether (a) omeprazole 20 mg tds (3 months) improves symptoms and laryngitis, and (b) the outcome in response to potent acid suppression can be predicted by esophageal and/or pharyngeal parameters during ambulatory pH monitoring or by other pretreatment variables. METHODS: From the 70 consecutive patients with laryngitis screened, 20 patients met the inclusion criteria (dysphonia >3 months; laryngoscopically demonstrated laryngitis); and 50 patients were excluded because of one or more criteria indicating alternative causes for laryngeal injury. The primary outcome measure was improvement of at least one level in a 4-point laryngitis grading at 3 months. Twenty-four-hour dual, pharyngo-esophageal pH monitoring was performed at baseline. Secondary outcomes (symptom questionnaire; computerized voice analysis) were measured at baseline, and at 6 and 12 wk. RESULTS: Response rates at 6 and 12 wk were 47% and 63%, respectively. GERD symptoms (heartburn (p= 0.03) and regurgitation (p= 0.0001)) improved. However, neither baseline GERD symptoms nor endoscopic findings predicted laryngoscopic or symptomatic response. Neither baseline laryngitis grade (p= 0.46) nor esophageal acid exposure on pH testing (p= 0.3) predicted outcome. Four of 20 patients demonstrated pharyngeal regurgitation on pH testing, all four of whom responded to potent acid suppression (p= 0.2). Computerized voice measures were not predictive of outcome, although fundamental frequency (Fo) was inversely related to baseline laryngoscopic grade. CONCLUSION: In a carefully defined population of patients with laryngitis (a) 63% have a laryngoscopic response to 3 months of potent acid suppression without significant improvement in laryngeal symptoms; (b) neither voice measures, esophageal acid exposure time, symptoms nor severity of laryngitis predict outcome; and (c) although numbers were small, all patients with a positive pharyngeal pH study responded to therapy and pharyngeal pH-metry may prove useful; (4) available evidence supports an empiric trial of high-dose proton pump inhibitors (PPI), for at least 12 wk, as the initial diagnostic step for suspected reflux laryngitis.

Effect of aggressive therapy on laryngeal symptoms and voice characteristics in patients with gastroesophageal reflux.

Gastroesophageal reflux (GER) is associated with a variety of laryngopharyngeal signs and symptoms. Injury of the laryngopharynx as a result of GER can be refractory to conventional antireflux therapy. This prospective study was undertaken to evaluate the prevalence of laryngopharyngeal signs and symptoms in patients with documented GER and to assess the response to a high-dose combination antireflux therapy consisting of cisapride and pantoprazole. Twenty-two patients with symptoms of GER were enrolled. After baseline evaluation using a history questionnaire for symptoms, laryngeal endoscopy and vocal acoustic analysis, patients were started on treatment consisting of pantoprazole 40 mg b.d. and cisapride 20 mg twice daily. Repeat history and otolaryngologic evaluation was performed at 4 weeks. Laryngopharyngeal symptoms were frequent in most patients, with throat clearing and globus being the most prevalent symptoms followed by vocal fatigue and excess mucus production. Almost 90% of the patients had abnormal endoscopic laryngeal findings but the acoustic parameters did not show any abnormal results except for mild elevation in the shimmer. After treatment, all symptoms and endoscopic abnormalities improved significantly except for intermittent dysphonia and laryngeal mucosal redness. Acoustic abnormalities did not change significantly following therapy. Laryngeal symptoms and voice abnormalities are highly prevalent in patients with GER. Combination antireflux therapy with a proton pump inhibitor and a prokinetic agent results in rapid symptomatic and endoscopic response in the majority of patients.

[Laryngitis epidemic (893 cases of acute laryngotracheitis and spastic croup). II. Clinical, diagnostic and therapeutic aspects]. / Epidemia de laringitis (893 casos LTA y CE). II. Aspectos clínicos, diagnósticos y terapéuticos.

We retrospectively review 893 cases of children, occurred in epidemic bout in September-October 1987, in order to study the usual management of his pathology in our hospital. In most cases (82.3%) diagnose was laryngitis or acute laryngitis without specification acute laryngotracheitis or spasmodic group. Epiglottitis was no detected in any case. Complementary tests were performed only in 5% of the patients, but they were of little help for the diagnose. Treatment applied was ambiental hummidiffication (95.5%), followed by water and alcohol impregned neck collar (87.2%), rectal magnesium-sulfate + papaverine (67.5%), epinephrine nebulization (63%), antibiotics (44.3%), steroids (9%), bronchodilatadors (4.8%). This therapeutic approach is discussed.

[Transconioscopy of the larynx--10 years' experience (author's transl)]. / 10-Jahres-Erfahrung mit der Transkonioskopie in der laryngologischen Diagnostik.

Transconioscopy is an additional aid to the diagnosis, localization and functional consequences of laryngeal lesions. This endoscopic examination is especially relevant to management. The technique is described and the findings in a large number of cases are demonstrated.

Fibreoptic laryngoscopy in the assessment of laryngeal disorders.

The fibreoptic laryngoscope is described, and its method of use detailed. Seventy patients were submitted to this examination. Its advantages and disadvantages in the assessment of the various groups of laryngeal disorders in these patients are discussed and compared with indirect and direct laryngoscopy. Its teaching and research possibilities are also mentioned. The technique shows considerable promise and will, we believe, achieve an accepted place as an addition to our diagnostic armamentarium in the investigation of laryngeal disorders.
