ABSTRACT
BACKGROUND/OBJECTIVES: Situated at the center of the upper aerodigestive tract, the larynx often is susceptible to a variety of insults including infection. Manifestations of laryngitis include hoarseness, cough, and sore throat, among others. The purpose of this research is to better understand the clinical presentation and patient characteristics of chronic infectious laryngitis. We aim to better understand when culture-directed therapy should be initiated in patients presenting to the otolaryngologist with suspected chronic infectious laryngitis and how this may influence treatment outcomes. METHODS: A single center, retrospective chart review was performed for patients with laryngitis of >3 weeks duration and who had positive laryngeal cultures obtained at a tertiary referral laryngology office from January 2016 through January 2023. RESULTS: Twenty-four patients (ages 36-84 years) with 29 positive cultures of the larynx met inclusion criteria. Ninety percent of patients were already on acid suppression therapy prior to culture acquisition. Fifty-five percent were immunocompromised. The most common species of bacterial growth included Klebsiella sp. (27.5%), Staphylococcus sp. (27.5%), and methicillin-resistant staphylococcus sp. (13.7%). Twelve cultures (41.4%) revealed multiple bacterial species, and 10 cultures (34.5%) had concomitant fungal isolates. The average treatment duration was 10 days. Twenty-one patients (72%) experienced improvement or resolution in symptoms after completion of culture-directed therapy. CONCLUSIONS: The use of culture-directed therapy for chronic bacterial laryngitis was helpful in the determination of appropriate treatment in these cases. More studies are needed to determine the optimal timing of cultures, duration of treatment, and implications of concomitant fungal laryngitis. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:335-339, 2024.

OBJECTIVE: Acute infectious laryngitis is commonly occurred among children. Our study sought to investigate the effect of inhaled budesonide on among children with acute infectious laryngitis. METHODS: A total of 92 children with acute infectious laryngitis were randomly allocated to either the study (46 cases, treated with inhaled budesonide) and control group (46 cases, treated with dexamethasone). The disappearance time of symptoms, therapeutic effect and adverse reactions were observed in the two groups. RESULTS: The therapeutic effect was significantly better in the study group than in the control group (97.83% vs 82.61%). After 3 days of treatment, the disappearance time of symptoms, such as hoarseness/barking cough, singing sound in the throat, three-concave sign and dyspnea in the study group was significantly less than that in the control group (P < 0.05). The levels of IL-4, IL-17, MMP-9, IL-33, IFN-γ and IgE in the two groups decreased, and evidently lower levels were found in the study group as compared to the control group (P < 0.05). CONCLUSION: Inhaled budesonide exerted obvious better effect in terms of reducing serum inflammatory factors and improving the quality of life with safety profile.

Postbiotics have recently been tentatively defined as bioactive compounds produced during a fermentation process (including microbial cells, cell constituents and metabolites) that supports health and/or wellbeing. Postbiotics are currently available in some infant formulas and fermented foods. We systematically reviewed evidence on postbiotics for preventing and treating common infectious diseases among children younger than 5 years. The PubMed, Embase, SpringerLink, and ScienceDirect databases were searched up to March 2019 for randomized controlled trials (RCTs) comparing postbiotics with placebo or no intervention. Seven RCTs involving 1740 children met the inclusion criteria. For therapeutic trials, supplementation with heat-killed Lactobacillus acidophilus LB reduced the duration of diarrhea (4 RCTs, n = 224, mean difference, MD, -20.31 h, 95% CI -27.06 to -13.57). For preventive trials, the pooled results from two RCTs (n = 537) showed that heat-inactivated L. paracasei CBA L74 versus placebo reduced the risk of diarrhea (relative risk, RR, 0.51, 95% CI 0.37-0.71), pharyngitis (RR 0.31, 95% CI 0.12-0.83) and laryngitis (RR 0.44, 95% CI 0.29-0.67). There is limited evidence to recommend the use of specific postbiotics for treating pediatric diarrhea and preventing common infectious diseases among children. Further studies are necessary to determine the effects of different postbiotics.

BACKGROUND: The incidence of Taralomyces marneffei infection in HIV-infected individuals has been decreasing, whereas its rate is rising among non-HIV immunodeficient persons, particularly patients with anti-interferon-gamma autoantibodies. T. marneffei usually causes invasive and disseminated infections, including fungemia. T. marneffei oro-pharyngo-laryngitis is an unusual manifestation of talaromycosis. CASE PRESENTATION: A 52-year-old Thai woman had been diagnosed anti-IFNÉ£ autoantibodies for 4 years. She had a sore throat, odynophagia, and hoarseness for 3 weeks. She also had febrile symptoms and lost 5 kg in weight. Physical examination revealed marked swelling and hyperemia of both sides of the tonsils, the uvula and palatal arches including a swelling of the epiglottis, and arytenoid. The right tonsillar biopsy exhibited a few intracellular oval and elongated yeast-like organisms with some central transverse septum seen, which subsequently grew a few colonies of T. marneffei on fungal cultures. The patient received amphotericin B deoxycholate 45 mg/dayfor 1 weeks, followed by oral itraconazole 400 mg/day for several months. Her symptoms completely resolved without complication. CONCLUSION: In patients with anti-IFN-É£ autoantibodies, T. marneffei can rarely cause a local infection involving oropharynx and larynx. Fungal culture and pathological examination are warranted for diagnosis T. marneffei oro-pharyngo-laryngitis. This condition requires a long term antifungal therapy.

Chronic laryngitis commonly presents with dysphonia, and infectious causes include tuberculosis and endemic mycoses. We present a 58-year-old female with laryngitis for 5 years, fevers, chills, fatigue, malaise, myalgias, anterior neck pain, and night sweats after multicontinent exposure. Bronchoscopy cultures were negative. Bilateral microflap excision of vocal fold lesions demonstrated thickened epithelium and a deep vocal fold mass. Biopsy showed necrotizing granulomatous inflammation with acid-fast bacilli. Mycobacterium kansasii was identified. Treatment led to improvement in dysphonia, systemic symptoms, and vocal fold irritation. To our knowledge, this is the first case of isolated nontuberculous mycobacterial vocal fold infection.

OBJECTIVES: Describe the demographics and clinical manifestations of laryngeal cryptococcosis. Develop a simple approach to the diagnostic workup and treatment of localized laryngeal cryptococcal infection. METHODS: A new case of laryngeal cryptococcosis encountered at our institution is presented and placed in context of the literature surrounding prior reported cases. PubMed, Google Scholar, SCOPUS, and Web of Science were queried from inception to August 2018 with the terms Larynx or Laryngeal and Cryptococcosis or Cryptococcus by two independent reviewers for English-language cases of cryptococcal infection of the larynx. RESULTS: Twenty-nine unique cases of laryngeal cryptococcosis were identified. Median age at presentation was 65 years old. All patients presented with persistent or progressive hoarseness. Lesions were predominantly on the true vocal cords (79%), 38% associated with an adherent white exudate or leukoplakia. A minority (28%) was immunocompromised, and of the remaining immunocompetent hosts, 67% were found to be using nebulized or inhaled corticosteroids (ICS) prior to infection. Diagnosis should be suspected in patients with chronic laryngitis or mass lesions with the aforementioned risk factors. Diagnosis was made by histopathology with cryptococcal yeasts identified on methenamine silver (55%) and/or mucicarmine stains (48%). Serum cryptococcal antigen testing was unreliable (sensitivity = 39%). The mainstay of effective treatment was prolonged oral Fluconazole therapy, with two cases of laser therapy ablation of residual lesions. Improvement in voice and vocal lesions varied from weeks to months. CONCLUSIONS: Laryngeal cryptococcosis is a rare cause of persistent hoarseness, which appears to be clinically evolving and more frequently affecting immunocompetent hosts chronically using nebulized or inhaled corticosteroids. Laryngeal cryptococcal infection is readily treatable with prolonged oral antifungals once biopsy and histopathological stains confirm the diagnosis.

A case of laryngeal actinomycosis occurred after bone marrow transplantation was reported. The patient was a 14-year-old girl who had a history of bone marrow transplantation for the treatment of acute lymphocytic leukemia 4month before the onset of the disease. She was referred to our hospital complaining persistent sore throat since 2weeks ago. Fiberscopic observation proved the presence of white tumor-like mass on her right arytenoid of the larynx. As CT image demonstrated that the mass was localized at the arytenoid region with central low-density area surrounded by granulation tissue, we underwent biopsy under local anesthesia. Excision of the mass proved it to be a soft granulation including sulfur granules. Oral administration of amoxicillin 750mg per day was initiated as a postoperative medication. On day 17, histological study confirmed that the tumor-like mass was Actinomyces granuloma, and therefore amoxicillin administration continued. The medication was effective to subside the disease and the arytenoid lesion healed on day 31. Amoxicillin was further administered until day 70 to prevent recurrence. At 6month after the biopsy, she was free from the disease.

OBJECTIVES: Chronic bacterial infection of the larynx is characterized by long-standing hoarseness and exudative laryngitis. Prolonged antibiotic therapy is required to clear the infection, and methicillin-resistant staphylococcus aureus (MRSA) may be the responsible pathogen. The objective of this study was to describe the presentation, comorbidities, treatment response, and underlying etiology- including the incidence of MRSA-in our patient population with chronic bacterial laryngitis. METHODS: A review of patients with a diagnosis of chronic bacterial laryngitis from 2012 to 2016 was performed. Diagnosis of chronic bacterial laryngitis was based on clinical history and findings on flexible laryngoscopy. In selected cases, the diagnosis of bacterial laryngitis was confirmed by operative biopsy. Information regarding clinical presentation and course was collected. RESULTS: Twenty-eight patients were included in the study. Twenty-three were treated empirically with Amoxicillin-clavulonic acid for a minimum of 21 days. Twelve of the 23 (52%) had recurrence or nonresolution of infection. Seven of the 12 nonresponders (58%) were found to have MRSA by laryngeal tissue culture. Five patients were treated initially with Sulfamethoxazole and trimethoprim, and all resolved the infection without the need for further treatment. There was a nonstatistically significant increase in smoking and reflux in the MRSA population compared to the non-MRSA group. CONCLUSION: MRSA infection was documented in 30% of patients overall with chronic bacterial laryngitis. Based on the results of the study, a treatment algorithm for management of this unusual patient population is suggested. LEVEL OF EVIDENCE: 4. Laryngoscope, 128:921-925, 2018.

The present article was designed to analyze the prevalence and clinical features of laryngomycosis associated with chronic inflammatory diseases of the larynx. We examined 430 patients suffering from chronic pharyngitis and found the fungal flora in 100 (23.2%) of them. Diagnostics of the fungal infection was performed by the microscopic study of the stained preparations (including the Gram method, Romanovskiy-Giemsa and fluorescent microscopy). The sowing on elective nutrient media was used. The study revealed the presence of yeast fungi (Candida) in 98 patients (98%) and mold fungi (Aspergillus) in the remaining two (2%). The hyperplastic form of fungal pharyngitis was diagnosed in 55% of the patients. We have identified the following predisposing factors for fungal laryngitis: the gastroesophageal reflux disease in 56% of the patients, smoking in 50%, the long-term use of the removable dentures with the inadequate care for them in 30%, and the consistent use of inhaled corticosteroids in 27%. Hyperglycemia was documented in 6% and the history of long-term treatment with antibiotics in in 10% of the patients. The scheme for the combined antifungal therapy has been developed. Its practical application allowed to achieve the eradication of the fungal flora and to improve the clinical course of chronic laryngitis in 75% of the patients.

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.

An 82-year-old supplemental oxygen dependent woman with severe COPD presented with an eight month history of worsening hoarseness and stridor. Office laryngoscopy revealed laryngeal edema and ulcerative masses throughout the larynx. In-office biopsies were positive for Cryptococcus neoformans. This report details a novel approach to the treatment of cryptococcal laryngitis, a combination of in-office pulsed-dye laser (PDL) ablation and medical therapy. Despite treatment with oral fluconazole, the recommended treatment for cryptococcal laryngitis the patient continued to be symptomatic with dysphonia and throat discomfort. Repeated laryngeal exam demonstrated persistent cryptococcal nodules. The patient was subsequently effectively treated with an in-office PDL laser. This case demonstrates the efficacy of in-office laser treatment for residual laryngeal Cryptococcus. For patients like this one, who have failed medical therapy and are unfit for general anesthetic, the in-office laser provides an excellent alternative treatment approach.

Introducción: La laringitis fúngica es una patología poco planteada en pacientes inmunocompetentes, sin embargo se debería tener en consideración en el diagnóstico diferencial de leucoplaquias en estos pacientes, más aún con factores predisponentes como reflujo faringolaríngeo, tabaquismo crónico y/o uso de corticoides. Objetivo: Presentar una serie de casos de pacientes inmunocompetentes con diagnóstico clínico de laringitis fúngica y tratamiento antimicótico empírico. Describir la asociación con factores predisponentes claves. Material y método: Estudio retrospectivo que incluyó a 11 pacientes con diagnóstico clínico de laringitis fúngica por correlación de la clínica, factores predisponentes y hallazgos en la videoestroboscopía laríngea (leucoplaquias múltiples en los pliegues vocales) sumado a la respuesta a tratamiento empírico con fluconazol oral. Se realizó además una revisión de la literatura disponible hasta el año 2015. Resultados: Todos los diagnósticos fueron clínicos correlacionando síntomas con hallazgo de leucoplaquias características en la laringe. El principal factor asociado fue el reflujo faringolaríngeo (91%) seguido por uso de corticoides (55%). Todos los pacientes fueron tratados con un esquema empírico de fluconazol oral por 14-21 días. El 100% de los pacientes respondió de forma exitosa al uso de este fármaco con remisión de los síntomas y de las lesiones laríngeas. Conclusión: El diagnóstico clínico y tratamiento con fluconazol oral como tratamiento de primera línea generarían buena tasa de respuesta, siempre que se correlacionen los síntomas y signos del paciente con los hallazgos encontrados en la laringe.
Introduction: The fungal laryngitis is an unusual disease in immunocompetent patients, however should take into consideration in the differential diagnosis of leukoplakias, especially in patients with predisposing factors such as pharyngolaryngeal reflux, use of inhaled, oral or intravenous corticosteroids. Aim: Describe a series of cases of fungal laryngitis in immunocompetent patients with clinical diagnosis and empirical antifungal treatment. In addition, finding the association with predisposing factors keys. Material and method: Retrospective study of 11 patients with diagnosis of fungal laryngitis according to clinical presentation, predisposing factors and findings in the laryngeal videostroboscopy (vocal folds leukoplakias) joined the response to empirical treatment with oral fluconazole. Also an extensive literature review was conducted until 2015. Results: The main predisposing factor was the pharyngolaryngeal reflux (91%) followed by use of corticosteroids (55%). All patients were treated empirically with fluconazole for 14-21 days. 100% of patients responded successfully, with remission of symptoms and laryngeal lesions. Conclusion: Clinical diagnosis and treatment with fluconazole as first-line treatment generate good response rate, provided that the patient's symptoms and signs with the findings in the larynx are correlated.

The objective of the present study was to evaluate the clinical state of the larynx and its microbial population in 49 patients examined at the stage of stable condition of chronic obstructive pulmonary disease. Examination of the larynx was carried out with the use of a rigid laryngoscope having a visual angle of 70 degrees, videofibrolaryngoscopy, and stroboscopy using a «TelePac¼ videocomplex (Karl Storz, Germany). It was supplemented by the study of the bacteriological and mycological paysage. The acoustic analysis of the voice was performed with the help of the Specta PLUS computer program. It was shown that more than 70% of the examined patients presented with various forms of chronic laryngitis. Potentially pathogenic St. pyogenes and yeast-like fungi C. albicans were isolated from 59% and 29% of the patients respectively.

OBJECTIVE: To review the recent diagnosis and treatment experience with deep neck infection and emphasize the importance of radiologic evaluation, microbiology and appropriate treatment selection in these patients. METHODS: A respective review was conducted in 95 cases who were diagnosed as having deep neck from Jan. 2006 to March 2015. RESULTS: The primary diseases in 95 patients with deep neck infection were acute tonsillitis or acute laryngitis (27 cases), infection of upper respiratory tract (23 cases), odontogenic infection or oral inflammation (16 cases), foreign bodies in esophagus (9 cases), acute cervical lymphadenitis (5 cases) and cause uncertain (15 cases). Computed tomography was performed in all of patients to identify the location, extent, and character (cellulitis in 47 cases or abscesses in 48 cases) of the infections. The locations of abscess were parapharyngeal abscess (25 cases), retropharyngeal abscess (9 cases), submaxillary space abscess (6 cases), pretracheal space abscess (5 cases) and esophageal abscess (3 cases). COMPLICATIONS: mediastinitis (2 cases), pericarditis (1 case), bilateral pneumothorax (2 cases), and upper digestive tract (1 case). Bacterial cultivation performed in 35 patients and positive results were detected in 21. All patients were given intravenous antibiotic therapy. Tracheotomy was performed in 4 cases. Preoperative contrast enhanced CT was performed in 42 patients and indicated the formation of abscess. Three cases with the symptoms of septic shock were transferred to ICU and one was cured. All the patients were cured except two who died of massive hemorrhage of upper digestive tract and septic shock. CONCLUSIONS: The airway patency in patients with deep neck infections must be ensured. Drainage may be mandatory in selected cases at presentation or in cases who fail to respond to parenteral antibiotics within the first 24-48 hours. Imaging evaluation plays a significant role in the diagnosis and rational therapeutic management in deep neck infection. Bacterial cultivation can help to make the effective treatment and provide reliable evidence for the etiopathogenisis.

PURPOSE OF REVIEW: The importance of bacterial biofilm in the human body, both when associated in chronic infections and as the default mode of microbial growth in the normal flora, has been understood during the last two decades. The word biofilm has recently entered into clinical vocabulary especially in dentistry, and oral hygienists have begun to talk of oral or dental biofilm instead of oral plaque. Biofilm presence has been demonstrated widely in otorhinolaryngology, related to chronic infections of middle ear, paranasal sinuses and lymphoid tissue of adenoids and tonsils and to implanted materials; however, less literature exists considering the implication of biofilm to laryngeal infections or head and neck cancer. The research until now has been mainly descriptive and the mechanisms that lead to biofilm formation are unclear and thus there are limited options for specific treatment of biofilm infection. The focus of this article is to review the recent literature considering the bacterial biofilm in larynx and in head and neck surgery. RECENT FINDINGS: Bacterial biofilm has now also been implicated in chronic laryngitis. Among head and neck cancer patients, biofilm is the main reason for the short life cycle of indwelling devices such as voice prostheses and tracheal tubes. Recently, bacterial biofilm has been related to dysplasia and malignancies both as an aetiological factor and as a source of complications. SUMMARY: It has been shown that microbial biofilm is implicated in the mechanisms leading to chronic recalcitrant infections, implant contamination and even to dysplasia. Biofilm has an important role in finding new preventive measures and treatment of these diseases.

BACKGROUND: Iatrogenic laryngotracheal stenosis (LTS) continues to be a known complication of indwelling endotracheal tubes (ETTs). It is well established that secondary scar formation caused by inflammation and mucosal injury are the main mechanisms by which stenosis occurs. Additionally, there are reports of bacterial colonization of ETTs and its potential association with tracheal scar formation. We describe 4 cases of patients with history of intubation and/or tracheostomy and presumed LTS that improved with the management of concurrent bacterial laryngotracheitis. METHODS: A retrospective case series of 4 subjects initially diagnosed at a tertiary care center with posterior glottic or subglottic stenosis and positive bacterial laryngotracheal cultures was performed. RESULTS: All 4 patients with presumed LTS had culture-proven bacterial growth isolated from the laryngotrachea and were treated with adjunct antibiotics. In the first 3 cases, complete resolution of upper airway obstruction was achieved. The fourth patient had notable improvement in her airway status without the need for additional surgical intervention. CONCLUSION: This case series suggests that bacterial growth within the airway may play a larger role in adult postintubation airway injury. Those patients presenting with concern for LTS and symptoms suspicious for an ongoing bacterial infection may benefit from adjunct antibiotic therapy.

Recurrent staphylococcal skin and soft tissue infections may recur despite decontamination and multiple courses of antibiotic therapy and may dramatically impair the patient's quality of life. We report successful use of long-term azithromycin prophylaxis in a recurrent laryngitis and a scalp folliculitis due to methicillin-susceptible Staphylococcus aureus.
