RESUMEN
BACKGROUND: Antimicrobial resistance (AMR) is an important global public health concern in adults and children. Laryngotracheobronchitis (croup) is a common acute respiratory infection (ARI) among children, most often caused by a virus, and should not be treated with antibiotics. Reducing the usage of unnecessary antibiotics in ARI using an antimicrobial stewardship program (ASP) is an effective measure against AMR in children. This study investigates the antibiotic prescription pattern in pediatric patients with laryngotracheobronchitis in Korea. Our results will be useful to improve the ASP. METHODS: The data were obtained from the government agency Health Insurance Review and Assessment Service. We analyzed outpatient prescriptions issued to children ≤ 5 years of age with a first-listed diagnosis code for laryngotracheobronchitis, i.e., International Classification of Disease, 10th Revision, code J050 (croup), J040 (laryngitis), or J041 (tracheitis), during 2017-2020. For each prescription, demographic information and information about medical facilities visited (type of hospital, specialty of physician, location of hospital) were extracted. The overall antibiotic prescription rate was subsequently estimated, and multivariable analysis was conducted to determine the associated factors of antibiotic prescription. Prescribed antibiotics were described and classified into extended-spectrum penicillins, cephalosporin, and macrolides. RESULTS: Of 2,358,194 prescriptions reviewed, 829,172 (35.2%) contained antibiotics. In the multivariable analysis, management in a hospital was the strongest factor associated with antibiotic prescription (adjusted odds ratio [aOR], 22.33; 95% confidence interval [CI], 20.87-23.89; P < 0.001), followed by management in a clinic (aOR, 12.66; 95% CI, 11.83-13.54; P < 0.001) and management in a general hospital (aOR, 8.96; 95% CI, 8.37-9.59; P < 0.001). Antibiotic prescription was also significantly associated with patients who were ≤ 2 years of age, managed by a pediatric specialist, and treated at a hospital located in a non-metropolitan region. Overall, extended-spectrum penicillins were the most frequently prescribed (18.6%) antibiotics, followed by cephalosporins (9.4%) and macrolides (8.5%). CONCLUSION: The results of our study suggest that ASPs need to focus on physicians in hospitals, clinics, general hospitals, and pediatric specialties. Providing education programs to these groups to increase awareness of AMR and appropriate antibiotics use could be effective ASP policy and may help to reduce unnecessary prescriptions of antibiotics for laryngotracheobronchitis among pediatric patients and therefore potentially AMR in children in Korea.

INTRODUCTION: Flexible endoscopic procedures (FEP) using a working channel allowed otolaryngologists to perform more procedures on the pharynx and the larynx under local anesthesia. The purpose of this work is to demonstrate the feasibility and safety of this technique by studying the adverse effects of this practice in an office-based setting. METHODS: This is a monocentric retrospective cohort study. We searched the database using the French procedural code for FEP performed in an outpatient setting between January 2005 and December 2020. Data regarding the patient's characteristics, indications, and periprocedural complications were extracted. RESULTS: In total, we included 231 patients with a total of 308 FEP: 36% biopsy, 20% hyaluronic acid injection (including 3.5% at the level of the cavum), 20% injection of other substances (in descending order: botulinum toxin, cidofovir, physiological serum, cortisone), 20% exploration for an occult tumor, 3% samples for microbiological analysis, 1% other procedures. Of the 308 FEP included in this study, 24 patients (10.3%) had complications corresponding to 7.8% of the procedures performed. During the procedures, reported complications include minor laryngeal bleeding (n = 5), vasovagal syncope (n = 5), laryngospasm (n = 1) or nausea (n = 3), dysphagia (n = 3), and voice disorders (n = 3). Post-procedural complications were hypertensive crisis (n = 1), asthma attack (n = 1), pneumonia (n = 1), laryngitis (n = 1). Using the Clavien-Dindo classification system, these complications could be defined as grade I (laryngeal bleeding, vasovagal syncope, laryngospasm, dysphagia, nausea, voice disorders, and laryngitis) and grade II (hypertensive crisis, asthma attack, pneumonia) in 9.1% and 1.2% of cases, respectively. Most of these complications were self-limiting, while asthma attacks, pneumonia, laryngitis, and voice disorders required a medical intervention. All complications were managed without sequelae. There was no serious complication grade (no grade III, IV or V). CONCLUSIONS: FEP, which is now well standardized in our institution, makes it possible to carry out a wide range of interventions with little morbidity. These results are in line with those of literature but this technique remains out of nomenclature in France. Our experience led to the development of an evidence-based standard of care that can serve as a framework for practitioners on a nationwide level, while the work to establish official guidelines by the French society of phoniatrics and laryngology is in progress.

BACKGROUND: Prolonged ulcerative laryngitis is a rare, benign inflammatory alteration of the larynx that persists for months. The laryngoscopic findings suggest a malignant process and can therefore be a challenge for the treating ear, nose and throat (ENT) physician. OBJECTIVES: Presentation of the current database to provide an overview of the etiology, progress and treatment for everyday clinical practice. METHODS: Three case studies from the Department of Phoniatrics and Speech Pathology of the ENT Department, University Hospital Zurich, Switzerland, are presented. Analysis and discussion of the current literature base and of case reports in the English literature. RESULTS: The etiology and predisposing factors for this disease are unclear. Previous respiratory infection with cough and dysphonia seems to be the most common cause. Biopsies should be avoided. CONCLUSIONS: The typical laryngoscopic findings show corresponding circumscribed lancet-shaped ulcerations in the middle third of the vocal fold. The course of the disease appears to be self-limiting and without permanent structural consequences. Therefore, good patient education and close laryngoscopic follow-up should be performed.

The voice as the most important means of communication is of great importance in a person's life. Every year the number of specialties for which voice and speech are a key tool of professional activity increases. Diseases of the vocal apparatus reduce the ability to work, and for some people pose a threat of professional unfitness. The relevance of the study is determined not only by the significant prevalence of dysphonia, but also by the insufficient effectiveness of existing methods of treating voice disorders. OBJECTIVE: To evaluate the clinical efficacy and safety of the use of the drug Homeovox in patients with acute and chronic catarrhal laryngitis as monotherapy. To fulfill the set goal of the study, the following tasks were solved: evaluation of the clinical effectiveness of the drug Homeovox as monotherapy for various types of dysphonia; evaluation of the effectiveness of the drug Homeovox as monotherapy from the 1st day of use. MATERIAL AND METHODS: The basis for the implementation of the tasks was the analysis of the results of the examination and treatment of 60 patients with voice disorders aged 18 to 75 years. Among them, 10 (17%) patients with acute laryngitis and 50 (83%) patients with chronic laryngitis. To establish the diagnosis, a comprehensive examination was carried out, involving examination, videolaryngostroboscopy, acoustic analysis of the voice. The study design included three patient visits, during which the functional state of the vocal apparatus was examined by subjective and objective methods. RESULTS: As a result of the treatment with the use of the drug Homeovox, the efficacy and safety of this drug in the treatment of dysphonia in adult patients with acute and chronic laryngitis from the first days of therapy has been proven, which is confirmed by the method of videolaryngostroboscopy and acoustic analysis of the voice. CONCLUSION: The drug Homeovox is an effective, safe remedy and can be included in the complex treatment of laryngeal pathology in order to increase its effectiveness and achieve a therapeutic effect in a shorter time, manifested by an improvement in the clinical and functional state of larynx.

OBJECTIVE: To improve the diagnosis of laryngeal disease in patients with gastroesophageal reflux disease (GERD). MATERIAL AND METHODS: 171 patients (89 (52%) men, 82 (48%) women) with non-erosive (39 (23%) people) and erosive (132 (77%) people) forms of GERD were examined. None of the patients made active complaints about the condition of the larynx and pharynx. The examination included a questionnaire, examination by an otorhinolaryngologist, and videoendolaryngoscopy. RESULTS: The survey revealed the presence of symptoms of otorhinolaryngological pathology in 74% of patients. Videolaryngoscopy revealed no laryngeal pathology in 55 (32%) patients, and signs of GERD-associated laryngitis were detected in 116 (68%) patients. The most common pathology was pachydermia in interarytenoid region - in 89 people, laryngeal granuloma was detected in 7 patients, leukoplakia - in 2 patients, chronic edematous polypous laryngitis - in 2 patients, benign laryngeal formations - in 9 patients. In patients with GERD (erosive and non-erosive forms), an asymptomatic course of chronic laryngitis associated with this pathology was observed in 44% of cases. In 52% of patients, pachydermia in interarytenoid region was diagnosed, of which every second had pronounced hyperplasia and folding of the mucous membrane in interarytenoid region, which must be differentiated from laryngeal cancer (in this case, patients should be under the dynamic supervision of an otorhinolaryngologist). Other precancerous formations of the larynx (granulomas and leukoplakia) were found in 5% of patients. Benign neoplasms of the larynx (polyps and cysts) were also detected in 5% of cases. CONCLUSIONS: Despite the high frequency of detection of otorhinolaryngological diseases in the examined patients with gastroesophageal reflux disease, none of the patients presented complaints related to the pathology of the larynx, which indicates the need for active detection of this pathology in this category of patients by questioning, questioning, as well as examination by an otorhinolaryngologist.

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.

BACKGROUND: The purpose of this study was to investigate the pathohistological status of mucous lining infected with Helicobacte pylori as the possible cause of chronic laryngitis and laryngeal carcinoma. MATERIALS AND METHODS: The prospective examination included 51 patients suffering from planocellular laryngeal cancer and 26 examinees suffering from chronic laryngitis. The examinees and the control group were subjected to esophagogastroduodenoscopy which described the local status of the esophagus and stomach. Two biopsy samplings are taken from the stomach antrum and corpus. One part of the biopsies was colored using the histological technique used in the pathohistological detection of H. pylori, while the other part was incorporated in paraffin cubes where the H. Pylori gene expression was determined using the deparaffinization and PCR method DNA isolation. RESULTS: In the group of examinees suffering from laryngeal tumor, there were a higher number of patients suffering also from chronic gastritis (32/51) than in the other group, suffering from chronic laryngitis (9/26). In the chronic laryngitis group, there were more examinees with acute gastritis (12/26) than in the examined group (11/51). The difference is statistically significant (p = 0.0457). CONCLUSION: Chronic gastritis and H. pylori infection are risk factors for laryngeal carcinoma formation; therefore, acute gastritis with helicobacter pylori infection must be immediately treated to not let infection to become chronic.

The article deals with optimization of treatment policy for singers with chronic catarrhal laryngitis. The survey sample is 51 singers with chronic catarrhal laryngitis of the age from 29 to 54 and the length of time worked from 8 to 22 years. The following methods are used: anamnesis, microbiological investigation, voice evaluation according to Visual Analog Scale (VAS), microlaryngoscopy, videolaryngostroboscopy, voice acoustic analysis (MDVP Kay Pentax system), statistical processing of results. It is shown that the cause of chronic catarrhal laryngitis in professional singers is non-bacterial irritants that provoke the appearance of an inflammatory process in the larynx, as well as uncontrolled use of drugs that irritate and dry out the mucous membrane and imperfect vocal technique. Pathogenic flora as an etiologic factor in the occurrence of laryngitis does not play an important role. A comprehensive treatment scheme for chronic catarrhal laryngitis using inhalation therapy and drugs that improve trophic processes in the laryngeal mucosa, which allows to increase the effectiveness of treatment and achieve stable remission of the disease, is suggested.

INTRODUCTION: Herpes zoster laryngitis (HZL) is a recently recognized rare disease, easily mistaken for common viral laryngopharyngitis. There are only a few case reports in the English literature. No study has evaluated the clinical characteristics of HZL. In this study, we analyzed the clinical characteristics of HZL and compared them to those of Ramsay Hunt syndrome (RHS). MATERIALS AND METHODS: Seventy-three patients who were initially diagnosed with HZL or RHS were enrolled in this study. Their medical records, including laryngoscopic findings, were analyzed retrospectively. The demographic factors, cranial nerve involvement, and recovery rate of both groups were evaluated. RESULTS: Sixty patients in the non-HZL group and 13 patients in the HZL group were analyzed. Five more patients in the non-HZL group were newly identified with HZL during the retrospective chart review. The mean age of the patients in the HZL group was higher than that of the non-HZL group (p = 0.016). The prevalence of hypertension was higher in the HZL group (p = 0.012). Patients with multiple cranial nerve involvement were more common in the HZL group (p < 0.001). In addition, the prognosis of facial weakness (p = 0.002) and multisensory dizziness (p = 0.006) was poor in HZL group. CONCLUSION: This study showed that a considerable proportion of HZL cases were misdiagnosed or overlooked if not suspected. Considering the poor prognosis of HZL patients with facial paralysis and dizziness, HZL should be diagnosed earlier and treated properly.

We analyzed the association of the level of mRNA expression of the main endocytosis receptor LRP1 and actin-binding proteins (ezrin, profilin-1, cofilin-1, and adenylyl cyclase-associated protein 1) with the development and metastasis of laryngeal and laryngopharyngeal squamous cell carcinoma. The mRNA expression was evaluated in paired tissue samples using quantitative reverse transcription real-time PCR (RT-qPCR) and SYBR Green reagents. The study included 38 patients with stage T1-4N0-1M0 laryngeal and laryngopharyngeal squamous cell carcinoma and 10 patients with chronic hyperplastic laryngitis or grade II-III epithelial dysplasia. The expression of LRP1 in patients with laryngeal and laryngopharyngeal squamous cell carcinoma depended on the stage of the tumor process. Against the background of low expression of LRP1 mRNA, the relationship between cofilin 1 and profilin 1 expression became stronger (r=0.08; p=0.05) and a correlation between cofilin 1 and esrin expression (r=0.7; p=0.05) appeared. Studies on a larger patient cohort are required to make a definite conclusion on the role of LRP1 in the development of laryngeal and laryngopharyngeal squamous cell carcinoma.

Voice is a work tool for many professional groups. Currently, cases of dysphonia of multiple origin consist a growing issue. Voice disorders may result from disturbed voice production process, congenital defects, post-traumatic conditions, chronic diseases or hormonal disorders. Chronic diseases causing voice disorders include laryngopharyngeal reflux disease and esophageal reflux disease.The chronic character of reflux causes the formation of numerous morphological changes of the larynx, including: hyperemia of the mucosa limited to arytenoid and intraarytenoid area, edema of the vocal folds, edema of the larynx mucosa. These changes contribute to voice disorders. Among the pathological changes of voice organ etiologically associated with reflux, the following disease units may be distinguished: reflux laryngitis, subglottic edema, contact ulceration, larynx granuloma, larynx and pharynx cancer. Many of disorders in the upper respiratory tract are etiologically related to reflux, e.g. dysphonia, grunting, coughing and dyspnoea.

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.

BACKGROUND: Although breastfeeding is touted as providing many health benefits to infants, some aspects of this relationship remain poorly understood. METHODS: The Environmental Determinants of Diabetes in the Young (TEDDY) is a prospective longitudinal study that follows children from birth through childhood, and collects data on illness events, breastfeeding duration, and time to introduction of formula or foods at 3 month intervals up until 4 years of age and at 6 months intervals thereafter. Exclusive and non-exclusive breastfeeding is examined in relation to the 3-month odds of a respiratory or gastrointestinal infection for 6861 children between the ages of 3-18 months, and 5666 children up to the age of 4 years. Analysis was performed using logistic regression models with generalized estimating equation methodology. All models were adjusted for potential confounding variables. RESULTS: At 3-6 months of age, breastfeeding was found to be inversely associated with the odds of respiratory infections with fever (OR = 0.82, 95% CI = 0.70-0.95), otitis media (OR = 0.76, 95% CI = 0.62-0.94), and infective gastroenteritis (OR = 0.55, 95% CI = 0.46-0.70), although the inverse association with respiratory illnesses was observed only for girls during the winter months. Between 6 and 18 months of age, breastfeeding within any 3 month period continued to be inversely associated with the odds of ear infection and infective gastroenteritis, and additionally with the odds of conjunctivitis, and laryngitis and tracheitis, over the same 3 month period within this age range. However, breastfeeding in this group was associated with increased reports of common cold. Duration of exclusive breastfeeding was inversely associated with the odds of otitis media up to 48 months of age (OR = 0.97, 95% CI = 0.95-0.99) after breastfeeding had stopped. CONCLUSIONS: This study demonstrates that breastfeeding can be protective against multiple respiratory and gastrointestinal acute illnesses in some children up to at least 6 months of age, with duration of exclusive breastfeeding being somewhat protective of otitis media even after breastfeeding has stopped.

The aim of the study was to evaluate the inflammatory reaction in children with pseudocroup and compare it with other laryngological diseases according to the available literature data. The study group included 51 children hospitalized because of pseudocroup. The measurements of the acute phase proteins (APP), such as C-reactive protein (CRP), alpha-1-antitrypsin (AT), alpha-1-antichymotrypsin (ACT), alpha-1-acid glycoprotein (AGP), ceruloplasmin (Cp), transferrin (Tf), alpha-2-macroglobulin (A2M), and haptoglobin (Hp) were obtained at 3 time points. The glycosylation profiles of AGP, ACT, and Tf were completed. An increased AGP level was observed in girls. The AGP glycosylation revealed the advantage of the W0 variant over the W1 variant. W1 and W2 were decreased in boys. W3 emerged in boys. The Tf concentration and T4 variant were lower compared to the control group. The A2M level was lower after treatment. The Hp and AT levels were decreased a few weeks later. The ACT glycosylation revealed a decrease of the A4 variant in boys. In conclusion, the inflammatory reaction during pseudocroup was of low intensity. The APP glycosylation suggested a chronic process. In a follow-up investigation, no normalization of the parameters was noted, but signs of persistent inflammation were observed.

PURPOSE: Acute supraglottic laryngitis (ASL) is manifested by supraglottic inflammation that has the potential for rapid and fatal airway obstruction. Complete/incomplete vocal fold immobility (VFIm) in the setting of ASL may contribute to airway obstruction. The rate of VFIm complicating ASL is not known, and it is not clear whether its occurrence alters the course and the management of ASL, particularly the need to secure the airway (by endotracheal intubation/tracheostomy). This study seeks to describe the natural history of VFIm associated with ASL (ASLIm) and to determine the added effect of VFIm on ASL severity, management, and the need for intervention to secure the airway. METHODS: This is a retrospective cohort study in a tertiary referral center. The medical records of all patients hospitalized due to ASL between January 2007 and December 2016 were reviewed. RESULTS: Of the 214 patients admitted due to ASL, VFIm was identified in 9 (4.2%). The VFIms resolved within 1-90 days in all 8 patients with available follow-up of 1-3 months. One patient required endotracheal intubation. The 9 ASLIm patients had significantly higher rates of hoarseness and a history of diabetes mellitus. There was no group difference in the need to secure the airway. CONCLUSIONS: VFIm is an apparently uncommon finding among patients with ASL. It appears to be usually transient, short-lasting, and full recovery can be expected. VFIm did not alter the ASL course, nor did it put our patients at increased risk for the need for intervention to secure the airway. LEVEL OF EVIDENCE: 4.

PURPOSE: To establish a novel and effective reflux model with a modified nasogastric aspiration tube and to investigate the association between different types of nasogastric aspiration tubes and reflux laryngitis, we conducted this study. METHODS: Thirty-eight healthy New Zealand albino rabbits (2.5-3.5 kg) were divided into three groups: control (CTR, n = 6)-non-intubated; normal nasogastric intubation (NNI, n = 16)-intubated with 4#, 6#, 8#, and 10# normal nasogastric aspiration tubes; and modified nasogastric intubation (MNI, n = 16)-intubated with 4#, 6#, 8#, and 10# modified nasogastric aspiration tubes. The laryngoscopy, body weight, and pH values at the esophageal entrance were recorded before and 1, 2, and 4 weeks after intubation. After the final laryngoscopy, the animals in groups with a pH below 4 were sacrificed to obtain histological and gene expression analysis results. RESULTS: The reflux finding score (RFS) after 4 weeks showed that there was a statistically significant difference in the 8# NNI group (7 ± 0.816, P < 0.001), the 8# MNI group (11.5 ± 2.517, P < 0.001) and the 10# MNI (12.75 ± 1.893, P < 0.001) group compared with the control group (1.83 ± 1.602). The pH values of these three groups were lower than 4. However, the weight loss of the rabbits in the 10# NNI and 10# MNI groups was more obvious. Submucous gland hyperplasia and inflammation were significantly increased in the 8# NNI group, 8# MNI group and the 10# MNI group, but in the level of some pro-inflammatory cytokines and COX-2, the MNI group was significantly higher than the NNI group (8# NNI × 8# MNI, P < 0.01; 8# MNI × 10# MNI, P < 0.01). CONCLUSION: This study showed that 8# modified nasogastric intubation (MNI) produces effective reflux laryngitis in the rabbits.

Subglottic pathologies are rare and show a clinical unspecific appearance i. e. through tissue increase around the cricoid or the cranial trachea. Typical symptoms are hoarseness, an overstimulated coughing, a globus laryngeus feeling as well as dyspnea or a stridor. Differential diagnosis include benign diseases like involving a posttraumatic status (e. g. stenosis), infection (i. e. pseudocroup), rheumatic disease (i. e. granulomatosis with polyangiitis) or benign tumor (i. e. papilloma, hemangioma or granular cell tumor). On the other hand, malignant diseases like the squamous cell carcinoma, a chondrosarcoma or the very rare laryngeal lymphoma manifestation must be considered as well. Idiopathic causes should also be taken into account. To secure the final diagnosis of such tumor formation a tissue sample should be histologically analyzed. The therapy is multimodal e. g. in close collaboration with internal medicine and ENT specialists.

Laryngitis is one of the commonest causes of dysphonia in the subjects engaged in the voice and speech professions. This condition can be either associated with the professional activities or related to voice fatigue. It is a common practice to distinguish between acute and chronic forms of occupational laryngitis. The main factors responsible for development of both conditions include the non-observance of directions concerning the protection and hygiene of the speaking and singing voice. The present study included 478 (100%) subjects engaged in the voice and speech professions presenting with the diagnosis of acute or chronic occupational laryngitis who applied for medical assistance to our Phoniatric Care Department. The clinical state of their larynx was evaluated with the use of the videoendostroboscopic technique. Acute laryngitis was diagnosed in 103 (21.5%) of the examined subjects while the remaining 375 (78.5%) ones presented with chronic laryngitis. A characteristic feature of acute occupational laryngitis documented in 38 (36.9%) examined professional voice users with this condition (practically healthy in all other respects) was the development of this disorder as a result of overloading the speech organs. On the contrary, viral and/or bacterial laryngitis revealed in 65 (63.1%) of the patients was preceded by acute respiratory symptoms. A total of 62 (16.5%) patients suffered from chronic occupational laryngitis attributable to overloading of the organs of speech during protracted periods. The remaining 313 examined professional voice users were found to present with various forms of chronic laryngitis including catarrhal laryngitis in 175 (46.7%) of them, edematous-polypoid and atrophic forms in 32 (8.5%) and 19 (5.1%) subjects respectively. The main etiological factors underlying the development of all the tree forms of chronic laryngitis were smoking, chronic tonsillitis, gastroesophageal reflux disease, bronchial asthma, and diabetes mellitus.

BACKGROUND: Mycobacterium arupense, first identified in 2006, is a slow-growing nontuberculous mycobacterium (NTM) and an emerging cause of tenosynovitis, potentially associated with immunosuppression. However, unlike the diagnostic value of its isolation from osteoarticular specimens, the significance of detecting M. arupense in respiratory specimens is not yet clear. CASE PRESENTATION: To our knowledge, we, for the first time, described the identification of M. arupense from the pleural effusion of an immunocompetent patient, who presented with fever and chylothorax. The symptoms resolved with doxycycline treatment for 45 days and a low-fat, high-protein diet. Follow-up at 14 months showed no relapse. CONCLUSIONS: Because the patient fully recovered without combined anti-NTM treatment, we did not consider M. arupense the etiological cause in this case. This indicates that M. arupense detected in pleural effusion is not necessarily a causative agent and careful interpretation is needed in terms of its clinical relevance.
