Adult-onset nasopharyngeal diphtheria: an uncommon but rapidly progressive and potentially fatal infection.

Nasopharyngeal diphtheria is an acute infectious upper respiratory tract disease caused by toxigenic strains of Corynebacterium diphtheriae. We report a case of a young adult who presented to us with a short history of fever, sore throat, hoarseness of voice and neck swelling. He claimed to have received all his childhood vaccinations and had no known medical illnesses. During laryngoscopy, a white slough (or membrane) was seen at the base of his tongue. The epiglottis was also bulky and the arytenoids were swollen bilaterally. The membrane was sent to the microbiology laboratory for culture. A diagnosis of nasopharyngeal diphtheria was made clinically and the patient was treated with an antitoxin together with erythromycin, while awaiting the culture result. Nevertheless, the patient's condition deteriorated swiftly and although the laboratory eventually confirmed an infection by toxin-producing C. diphtheriae, the patient had already succumbed to the infection.

Primary Laryngeal Tuberculosis: Our Experiences at a Tertiary Care Teaching Hospital in Eastern India.

INTRODUCTION: Primary laryngeal tuberculosis is a chronic bacterial infection of the larynx by Mycobacterium tuberculosis without affecting the lungs. It is a rare type of extrapulmonary tuberculosis seen in clinical practice. OBJECTIVES: This study aimed to evaluate the clinical presentation, diagnosis, and treatment of primary laryngeal tuberculosis at a tertiary care teaching hospital in eastern India. MATERIALS AND METHODS: This is a retrospective study of 11 cases of primary laryngeal tuberculosis managed between December 2013 and January 2018. The detailed clinical presentations, investigations, and treatment of primary laryngeal tuberculosis of the patients were studied. RESULTS: Primary laryngeal tuberculosis is common in men with mean age of 38.63 years. Hoarseness of the voice is the most common symptom, and the most common site for primary laryngeal tuberculosis is the vocal fold with ulcerative lesion. Endoscopic examinations of the larynx in laryngeal tuberculosis are nonspecific and are to be confused with laryngeal cancer. Histopathological and bacteriological examinations are confirmatory tests for the diagnosis. After confirmation of the diagnosis, all patients had taken antitubercular therapy for 6 months, which gave excellent outcome. CONCLUSIONS: Delayed diagnosis or untreatable laryngeal tuberculosis will lead to high morbidity and mortality of the patient. Although primary laryngeal tuberculosis has nonspecific clinical presentations, it is very important to have a high index of suspiciousness to rule out tubercular lesion in the larynx as this disease is curable.

Histoplasmosis of the head and neck in the immunocompetent patient: Report of 2 cases.

Histoplasmosis of the head and neck is rarely seen in immunocompetent patients. We report 2 new cases of histoplasmosis of the head and neck in immunocompetent patients, one an 80-year-old man and the other a 57-year-old man. The older man presented with oral cavity histoplasmosis; his symptoms included pain, dysphagia, and ulcerative lesions. The younger man had laryngeal histoplasmosis, which resulted in hoarseness and dyspnea. We discuss the methods of diagnosis and the classic findings in histoplasmosis, including the microscopic appearance of caseating granulomas, the results of periodic acid-Schiff staining and Gomori staining, and antibody detection of histoplasmosis. We also review the treatment options with antifungals, including amphotericin B and the oral conazole drugs. With an accurate diagnosis and proper treatment, both of our patients recovered well and their symptoms resolved. Because their symptoms overlapped with those of other, more common disease processes, an accurate diagnosis of these patients was essential to treating their infection.

Indoor Air Problems and Hoarseness in Children.

OBJECTIVES: A well-functioning voice is becoming increasingly important because voice-demanding professions are increasing. The largest proportion of voice disorders is caused by factors in the environment. Moisture damage is common and can initiate microbial growth and/or diffusion of chemicals from building materials. Indoor air problems due to moisture damage are associated with a number of health symptoms, for example, rhinitis, cough, and asthma symptoms. The purpose of this study was to investigate if children attending a day care center, preschool, or school with indoor air problems due to moisture damage were hoarse more often than the children in a control group. METHODS: Information was collected through electronic and paper questionnaires from the parents of 6- to 9-year-old children (n = 1857) attending 57 different day care centers, preschools, or schools with or without indoor air problems due to moisture damage. RESULTS: The results showed a significant correlation between the degree of indoor air problem due to moisture damage and the frequency of hoarseness. Significant predictors for the child being hoarse every week or more often were dry cough, phlegm cough, and nasal congestion. CONCLUSIONS: The results indicate that these symptoms and exposure to indoor air problems due to moisture damage should be included in voice anamnesis. Furthermore, efforts should be made to remediate indoor air problems due to moisture damage and to treat health symptoms.

Association of laryngeal and nasopharyngeal tuberculosis: a case report.

INTRODUCTION: To the best of our knowledge, the association of nasopharyngeal and laryngeal tuberculosis has never been described before in the literature. We report here a first observation. CASE PRESENTATION: We report the case of a 38-year-old Arab man who presented with an isolated hoarseness. Radiological and endoscopic examinations showed a thickening of the left lateral wall of his nasopharynx and the left vocal cord. Pathology revealed the diagnosis of tuberculosis of both localizations. He received a 6-month antituberculous chemotherapy with a satisfying uneventful evolution. CONCLUSIONS: Tuberculosis should be considered in the differential diagnosis of soft tissue masses of the head and neck, particularly when the imaging findings and clinical presentation are atypical. The diagnosis of tuberculosis is mainly based on histopathological and/or bacteriological examination.

Invasive primary aspergillosis of the larynx presenting as hoarseness and a chronic nonhealing laryngeal ulcer in an immunocompetent host: a rare entity.

Primary aspergillosis usually affects the paranasal sinuses, orbit, ear, and lower respiratory tract. Laryngeal aspergillosis usually occurs as a result of secondary invasion from the tracheobronchial tree, more commonly in immunocompromised hosts. Primary laryngeal localization of Aspergillus infection is seldom encountered. We report the case of an immunocompetent 42-year-old man who presented with hoarseness and a laryngeal ulcer of fairly long duration. A malignancy was initially suspected clinically, but a laryngoscopic biopsy led to a diagnosis of invasive primary laryngeal aspergillosis. No other focus of aspergillosis was found on x-ray and computed tomography. After identification of Aspergillus niger on culture, inquiries revealed no exposure to steroids, cytotoxic drugs, or irradiation, and workups for malignancy, human immunodeficiency virus infection, tuberculosis, and diabetes were negative. Although isolated laryngeal involvement is rare, aspergillosis may be considered in the differential diagnosis of a chronic nonhealing laryngeal ulcer that is clinically suggestive of a malignancy, even in an immunocompetent host.

Vocal cord dysfunction related to water-damaged buildings.

BACKGROUND: Vocal cord dysfunction (VCD) is the intermittent paradoxical adduction of the vocal cords during respiration, resulting in variable upper airway obstruction. Exposure to damp indoor environments is associated with adverse respiratory health outcomes, including asthma, but its role in the development of VCD is not well described. OBJECTIVE: We describe the spectrum of respiratory illness in occupants of 2 water-damaged office buildings. METHODS: The National Institute for Occupational Safety and Health conducted a health hazard evaluation that included interviews with managers, a maintenance officer, a remediation specialist who had evaluated the 2 buildings, employees, and consulting physicians. In addition, medical records and reports of building evaluations were reviewed. Diagnostic evaluations for VCD had been conducted at the Asthma and Allergy Center of the Medical College of Wisconsin. RESULTS: Two cases of VCD were temporally related to occupancy of water-damaged buildings. The patients experienced cough, chest tightness, dyspnea, wheezing, and hoarseness when in the buildings. Spirometry was normal. Methacholine challenge did not show bronchial hyperreactivity but did elicit symptoms of VCD and inspiratory flow-volume loop truncation. Direct laryngoscopy revealed vocal cord adduction during inspiration. Coworkers developed upper and lower respiratory symptoms; their diagnoses included sinusitis and asthma, consistent with recognized effects of exposure to indoor dampness. Building evaluations provided evidence of water damage and mold growth. CONCLUSION: VCD can occur with exposure to water-damaged buildings and should be considered in exposed patients with asthma-like symptoms.

Cryptococcal infection of the larynx: case report.

OBJECTIVE: Laryngeal cryptococcosis is a rare condition. In this report, we describe the findings for and treatment of a 58-year-old man with Cryptococcus gattii infection of the right vocal fold. METHOD: Case report and review of the relevant English language literature. RESULTS: The patient presented with persistent hoarseness of voice. Laryngoscopy demonstrated an irregular, red lesion on the right vocal fold. Histopathological examination identified cryptococcus. The patient was treated with oral fluconazole 400 mg/day for eight weeks. CONCLUSION: Laryngeal involvement by Cryptococcus gattii can result from prolonged inhaled corticosteroid therapy and proximity to eucalyptus trees. The clinical presentation, laryngoscopic findings and imaging results of laryngeal involvement may mimic a neoplasm. Histopathological examination can demonstrate the causative organism. Management consists of advice from an infectious disease specialist together with adequate treatment by antifungal agents.

[Acute miliary tuberculosis or Isambert disease: a case report]. / Miliaire tuberculeuse aiguë du pharynx ou maladie d'Isambert : à propos d'un cas.

Pharynx tuberculosis consists in a set of active lesions in granulomatous-type mucosa, resulting from Mycobacterium tuberculosis infection. In an endemic context, this diagnosis should be raised in cases of head and neck disease. A recent observation of a case of acute miliary tuberculosis gave us the opportunity to conduct a literature review of this disorder. This 9-year-old girl presented with dysphagia associated with pharyngeal discomfort, snoring, and hoarseness lasting for 8 months. This pharyngeal syndrome occurred in the context of an impaired general condition. Clinical examination found a diffuse mucosal granulation aspect in the oropharynx. The workup showed an inflammatory syndrome with a strong positive intradermal tuberculin reaction. The biopsy found an aspect of giant cell granuloma with caseous necrosis. The course was favorable on antituberculous chemotherapy. Tuberculosis is a chronic bacterial infection caused by a bacterium belonging to the M. tuberculosis complex. Pharyngeal tuberculosis remains a rare disease, but several epidemiological parameters show an upsurge of this disease, prompting us to report this observation.

Laryngeal cryptococcosis: Clinical presentation and treatment of a rare cause of hoarseness.

OBJECTIVE: Laryngeal cryptococcosis is rare, with few reported cases in the literature. We present current investigation and treatment recommendations for this disease. STUDY DESIGN: A structured literature review; additional cases and expert opinion are presented. RESULTS: Localized laryngeal cryptococcal infection most commonly presents with persisting hoarseness. Clinical suspicion of the disease is required for accurate diagnosis, with treatment based on the patient's immune status. Early microbiological advice and adequate follow-up is recommended to ensure disease resolution. CONCLUSION: Isolated laryngeal cryptococcosis is a rare presentation of fungal infection. It is easily treated and should be considered in the differential diagnosis of patients with persisting hoarseness.

Hoarseness due to Mycobacterium kansasii.

OBJECTIVE: To present a case of unilateral vocal fold paralysis due to Mycobacterium kansasii induced pressure on the left recurrent laryngeal nerve, a specific aetiology not previously reported in the world literature. CASE REPORT: A 57-year-old Caucasian man presented with a short history of productive cough, fever, hoarseness and 14-kg weight loss. He was a smoker, had an abnormal chest X-ray and was human immunodeficiency virus negative. A sputum sample was positive on direct microscopy for acid fast bacilli. Initially, the patient was treated with Rifater (rifampicin, isoniazid and pyrazinamide) and ethambutol. Mycobacterium kansasii was isolated and proved sensitive to this antimycobacterial treatment. Nasoendoscopy revealed diminished movement of the left vocal fold, and a computed tomography scan showed enlarged mediastinal lymph nodes anterior to the aortic arch. After three months of antimycobacterial treatment, the vocal folds were fully mobile at repeat nasoendoscopy, and this coincided with gradual resolution of the patient's hoarseness and weight loss. CONCLUSIONS: There are many causes of unilateral vocal fold paralysis. This case illustrates the importance of anatomical knowledge in reaching a diagnosis, and also presents the first reported case of Mycobacterium kansasii creating this clinical picture.

Tuberculous aneurysm of extracranial carotid artery.

Incidence of extracranial carotid aneurysm is rare and represents a challenge to treatment strategy. Two patients presented to us a couple of years apart with pulsatile neck swellings. We propose that the extracranial carotid artery pseudoaneurysm was as a result of direct extension from tuberculous lymphadenitis and discuss the management of these patients.

Helicobacter pylori colonization in the larynges of patients with hoarseness.

OBJECTIVES: Vocal nodules and polyps are two common noninfectious causes of hoarseness. Patients with persistent hoarseness often require microscopic laryngeal surgery to excise mass lesions of the larynx despite extensive voice resting and modification of voice use behavior. Helicobacter pylori has recently been reported to present in the upper aerodigestive tract. This study applies the rapid urease test to determine the colonization of Helicobacter pylori in surgical specimens of patients with vocal nodules and polyps. METHODS: In this prospective study, 53 consecutive patients with vocal nodules (n = 20) or vocal polyps (n = 33) were investigated from November 2004 to July 2005. Microscopic laryngeal surgery was performed in all cases. Tissue specimens harvested from the larynx were analyzed using the rapid urease test. RESULTS: The study population consisted of 33 females and 20 males with a mean age of 43.1 +/- 9.9 years. Thirteen (24.5%) of the 53 patients revealed Helicobacter pylori colonization, and all were histopathologically diagnosed with vocal polyps. The difference in incidence of Helicobacter pylori colonization between vocal nodules and vocal polyps was statistically significant (0% [0/20] vs. 39.4% [13/33], P = .001). CONCLUSIONS: Helicobacter pylori often colonizes in the larynxes of patients with vocal polyps. These results indicate the involvement of Helicobacter pylori in vocal polyps. However, the presence of Helicobacter pylori as an etiologic factor in vocal polyps remains inconclusive.

Laryngeal tuberculosis: a review of 26 cases.

OBJECTIVES: To review the clinical characteristics of laryngeal tuberculosis. STUDY DESIGN: Retrospective case series. SUBJECTS AND METHODS: Medical records of 26 histopathology-confirmed cases in a tertiary medical center from 1992 to 2006. RESULTS: The female patients were significantly younger than male patients. Hoarseness is the most common symptom (84.6%) because true vocal fold is most commonly involved (80.8%). Infection usually involves unilateral (66.7%) and right-side larynx but multiple subsites of the larynx (57.7%). The appearance of the affected larynx may have mixed features and change before diagnosis. Laryngeal tuberculosis is usually misdiagnosed as laryngeal cancer, especially in patients with malignant signs such as enlarged cervical lymph nodes and vocal fold immobility. Chest film is better than sputum examinations for screening. CONCLUSION: We should be especially alert about TB infection when facing young female patients with unusual laryngeal lesions. Extensive laser excision before diagnosis should be avoided because after antituberculous treatment, prognosis is usually good and vocal fold immobility could be reversible.
