RESUMO
OBJECTIVES: To describe the occurrence of post-extubation laryngitis, analyze its one-year evolution, and correlate laryngeal lesions with clinical outcomes. METHODS: Retrospective study including children up to 13 years old at a tertiary hospital between March 2020 and March 2022 with diagnosis of post-extubation laryngitis confirmed by endoscopic examination. Exclusion criteria were prior history of intubation or anatomical airway abnormalities. Medical records were reviewed to characterize patients, underlying diagnosis, laryngeal lesions, treatment, and outcomes at 12-month follow-up. RESULTS: The study included 38 endoscopically confirmed post-extubation laryngitis cases, corresponding to 86.4% of suspected cases. The mean age was 13.24 months, and 60.5% were male. Acute respiratory failure was the leading cause of intubation. Initial treatment was clinical, and initial diagnosis was defined by nasopharynoglaryngoscopy and/or Microlaryngoscopy and Bronchoscopy (MLB) findings. Initial diagnostic MLB was performed in 65.7% of the patients. Approximately half (53%) of the patients exhibited moderate or severe laryngeal lesions. When compared to mild cases, these patients experienced a higher rate of extubation failures (mean of 1.95 vs. 0.72, pâ¯=â¯0.0013), underwent more endoscopic procedures, and faced worse outcomes, such as the increased need for tracheostomy (pâ¯=â¯0.0001) and the development of laryngeal stenosis (pâ¯=â¯0.0450). Tracheostomy was performed in 14 (36.8%) children. Patients undergoing tracheostomy presented more extubation failures and longer intubation periods. Eight (21%) developed laryngeal stenosis, and 17 (58.6%) had complete resolution on follow-up. CONCLUSION: Post-extubation laryngitis is a frequent diagnosis among patients with clinical symptoms or failed extubation. The severity of laryngeal lesions was linked to a less favorable prognosis observed at one-year follow-up. Otolaryngological evaluation, follow-up protocols, and increased access to therapeutic resources are essential to manage these children properly. LEVEL OF EVIDENCE: Level 4.

OBJECTIVES: To make recommendations on the diagnosis and treatment of post-extubation laryngitis (PEL) in children with or without other comorbidities. METHODS: A three-iterative modified Delphi method was applied. Specialists were recruited representing pediatric otolaryngologists, pediatric and neonatal intensivists. Questions and statements approached topics encompassing definition, diagnosis, endoscopic airway evaluation, risk factors, comorbidities, management, and follow-up. A consensus was defined as a supermajority >70%. RESULTS: Stridor was considered the most frequent symptom and airway endoscopy was recommended for definitive diagnosis. Gastroesophageal reflux and previous history of intubation were considered risk factors. Specific length of intubation did not achieve a consensus as a risk factor. Systemic corticosteroids should be part of the medical treatment and dexamethasone was the drug of choice. No consensus was achieved regarding dosage of corticosteroids, although endoscopic findings help defining dosage and length of treatment. Non-invasive ventilation, laryngeal rest, and use of comfort sedation scales were recommended. Indications for microlaryngoscopy and bronchoscopy under anesthesia were symptoms progression or failure to improve after the first 72-h of medical treatment post-extubation, after two failed extubations, and/or suspicion of severe lesions on flexible fiberoptic laryngoscopy. CONCLUSIONS: Management of post-extubation laryngitis is challenging and can be facilitated by a multidisciplinary approach. Airway endoscopy is mandatory and impacts decision-making, although there is no consensus regarding dosage and length of treatment.

OBJECTIVES: The purpose of this study was to evaluate visual gaze patterns and the ability to correctly identify cancer among participants of different experience levels when viewing benign and malignant vocal cord lesions. METHODS: Thirty-one participants were divided into groups based on level of experience. These included novice (medical students, PGY1-2 otolaryngology residents), intermediate (PGY3-5 otolaryngology residents, gastroenterology fellow), advanced practice providers (physician assistants, nurse practitioners, and speech language pathologists), and experts (board-certified otolaryngologists). Each participant was shown 7 images of vocal cord pathology including glottic cancer, infectious laryngitis, and granuloma and asked to determine the likelihood of cancer on a scale of certain, probable, possible, and unlikely. Eye tracking data were collected and used to identify the area of interest (AOI) that each participant fixated on first, fixated on the longest, and had the greatest number of fixations. RESULTS: No significant differences were seen among groups when comparing AOI with first fixation, AOI with longest fixation, or AOI with most fixations. Novices were significantly more likely to rate a low likelihood of cancer when viewing infectious laryngitis compared to more experienced groups (P < .001). There was no difference in likelihood of cancer rating among groups for the remaining images. CONCLUSIONS: There was no significant difference in gaze targets among participants of different experience levels evaluating vocal cord pathology. Symmetric appearance of vocal cord lesions may explain differences seen in likelihood of cancer rating among groups. Future studies with larger sample sizes will better elucidate gaze targets that lead to accurate diagnosis of vocal cord pathology.

CASE PRESENTATION: A 72-year-old woman with a history of adenocarcinoma of the lung, for which she was receiving tyrosine kinase inhibitor therapy with osimertinib, was admitted to the ED because of clinical deterioration with extreme fatigue and fever. She was already receiving antibiotic therapy initiated by her general practitioner because of symptoms of an upper respiratory tract infection. She was febrile (38.5 °C) with normal laboratory values except for leukocytosis and elevated C-reactive protein. She was hospitalized because of profound general malaise. On the basis of the physician's working hypothesis of severe viral laryngitis, the antibiotic therapy was stopped, and only supportive measures were taken. Over the next 3 days, her condition deteriorated, and she developed respiratory symptoms with a right-sided pleural effusion demonstrated by ultrasound examination. Over time, the patient became increasingly confused and drowsy. There was preserved urinary output and a stable glomerular filtration rate of 57 mL/min. Further on, bilirubin levels as well as coagulation were normal, indicating the absence of any relevant underlying chronic liver condition. Clinically, there were no signs of meningitis. No sedative medications that would explain her confusion were given except for low-dose opioid analgesics. On day 4 after hospitalization, she was transferred to the shock room for immediate stabilization and diagnostics because of profound encephalopathy and increasing oxygen requirements.

The terms hoarseness and dysphonia are used interchangeably, and both describe a type of altered vocal quality affecting one-third of patients. While hoarseness may be secondary to benign conditions such as reflux or viral laryngitis, it may suggest benign or malignant vocal-fold pathology. It is important for caregivers to know how to evaluate, treat, and when to refer patients for direct visualization via laryngoscopy. In this article, we review basic laryngeal anatomy and function, symptoms of vocal-fold pathology, and current guidelines from the American Academy of Otolaryngology-Head and Neck Surgery on the diagnosis and treatment of dysphonia, including patient referral.

OBJECTIVE: We aim to explore the clinical features and influencing factors of curative effect in children harboring acute laryngitis with laryngeal obstruction. METHODS: There involved 237 children with acute laryngitis and 80 healthy children who required physical examination in our hospital between January and September in 2021. The healthy children who required physical examination were allocated into the healthy/control group. The clinical data and laboratory indexes of each group were compared. We also analyzed the risk factors for curative effect of acute laryngitis with laryngeal obstruction among children using univariate/multivariate logistic regression. RESULTS: The incidence of barking cough, sore throat, dryness, pruritus, dyspnea, diffuse congestion and swelling of laryngeal mucosa and vocal cord congestion or covered with vascular striation in degree III laryngeal obstruction group were significantly higher than other study groups, with degree II laryngeal obstruction group higher than degree I group, and degree I group higher than no laryngeal obstruction group (P<0.05). Moreover, the levels of CRP, TNF-α, IL-6, IL-8 and WBC in degree III laryngeal obstruction group were higher than other three study groups, with degree II higher than degree I laryngeal obstruction group and no obstruction group, and degree I higher than no laryngeal obstruction group (P<0.05). Multivariate logistic regression analysis showed that CRP, TNF-α, IL-6 and IL-8 were the risk factors affecting the curative effect of acute laryngitis with laryngeal obstruction in children, and the differences were statistically significant (P<0.05). CONCLUSION: The study revealed the incidence of barking cough, sore throat, dryness, pruritus, dyspnea, diffuse congestion and swelling of laryngeal mucosa vocal cord congestion or covered with vascular striation is highly associated with the severity of acute laryngitis with laryngeal obstruction in children. Additionally, higher levels of CRP, TNF-α, IL-6, IL-8 and WBC indicated serious condition of the disease among children. Hence the risk factors responsible for the efficacy of acute laryngitis in children are CRP, TNF-α, IL-6 and IL-8.

OBJECTIVE: To establish if the Reflux Symptom Index (RFI) and the Reflux Finding Score (RFC) can help establish the differential diagnosis in patients with distinct causes of chronic laryngopharyngitis. METHODS: A group of 102 adult patients with chronic laryngopharyngitis (Group A - 37 patients with allergic rhinitis; Group B - 22 patients with Obstructive Sleep Apnea (OSA); Group C - 43 patients with Laryngopharyngeal Reflux (LPR)) were prospectively studied. Chronic laryngitis was diagnosed based on suggestive symptoms and videolaryngoscopic signs (RSIâ¯≥â¯13 and RFSâ¯≥â¯7). Allergies were confirmed by a positive serum RAST, OSA was diagnosed with a positive polysomnography, and LPR with a positive impedance-PH study. Discriminant function analysis was used to determine if the combination of RSI and RFS scores could differentiate between groups. RESULTS: Patients with respiratory allergies and those with LPR showed similar and significantly higher RSI scores when compared to that of patients with OSA (pâ¯<â¯0.001); Patients with OSA and those with LPR showed similar and significantly higher RFS scores when compared to that of patients with Respiratory Allergies (OSA vs. Allergies pâ¯<â¯0.001; LPR vs. Allergies pâ¯<â¯0.002). The combination of both scores held a higher probability of diagnosing OSA (72.73%) and Allergies (64.86%) than diagnosing LPR (51.16%). CONCLUSIONS: RSI and RFS are not specific for reflux laryngitis and are more likely to induce a false diagnosis if not used with diligence.

Coronavirus disease 2019 (COVID-19) occasionally causes acute laryngitis, requiring emergency treatment. Understanding the characteristic laryngeal findings can help diagnose COVID-19 earlier, prevent worsening infection, and properly manage airway obstruction. Herein, we report the case of a 44-year-old male with acute epiglottitis likely caused by COVID-19. On presentation, chest computed tomography (CT) showed no signs of pneumonia. However, the larynx had extensive necrotic-like erosive lesions resembling those of tuberculous laryngitis. COVID-19 was diagnosed by reverse-transcription polymerase chain reaction, and secondary bacterial superinfections were suspected after blood testing. The symptoms improved after administration of antibiotics (sulbactam sodium/ampicillin sodium), steroids (dexamethasone), and favipiravir. The patient developed a high fever on the sixth day of hospitalization, and pneumonia was identified on CT. Various culture tests, including tuberculosis, were negative. Thus, remdesivir was administered for COVID-19-induced pneumonia. The patient gradually recovered, was transferred to another hospital, and was discharged on the 35th day of hospitalization. Six previous case reports of COVID-19-induced acute epiglottitis suggested that acute epiglottitis preceded the onset of pneumonia. The laryngeal findings from this report may be useful for diagnosing COVID-19 that does not cause pneumonia and for bringing attention to pneumonia after a COVID-19 diagnosis.

BACKGROUND: Laryngopharyngeal reflux-associated symptoms embrace a wide variety of head and neck manifestations. Its participation in eye disorders has recently been postulated, and there is currently no consensus in this regard. The aim of this manuscript is to review the role of reflux in the development of ocular signs and symptoms, and its physio-pathological mechanisms. METHODS: A systematic approach based on the preferred reporting Items for a systematic review and meta-analysis checklist with a modified population, intervention, comparison, and outcome framework was used to structure the review process of studies that evaluated the possible association, with clear diagnostic methods, of laryngopharyngeal reflux and ocular signs and symptoms. Search was conducted in different indexed databases (PubMed/MEDLINE, the Cochrane Library, Scielo and Web of Science) and through the meta-searcher Trip Database with the keywords: reflux, laryngitis, laryngopharyngeal, gastroesophageal, ocular, eye, symptoms, signs, conjunctivitis, keratitis, dacryocystitis, dry eye. RESULTS: Seven studies met the inclusion criteria, in which the primary acquired nasolacrimal duct obstruction and the ocular surface disease were evaluated. The local increase of eye pepsin concentration (>2.5 ng/mL) may affect ocular surface though its direct proteolytic activity and the local expression of proinflammatory cytokines. The H. Pylori, with a similar mechanism to reach the lacrimonasal duct, would be associated with the release of proinflammatory and vasoactive substances that would lead to a mucosa injury and chronic inflammation. Ocular Surface Disease Index seems to correlate directly with the reflux severity, with cut-off of 41.67 score as predictor for disease. DISCUSSION: The role of laryngopharyngeal reflux in the development of ocular disorders has not yet been demonstrated and data are limited and heterogeneous. It seems theoretically conceivable that pepsin may reach lachrymal duct area through hypopharyngeal-nasal gaseous reflux events. Future studies using objective testing for diagnosis and pepsin detection into the tear and nasal mucosa are needed in order to explore this potential relationship.

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.

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.

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.

A 79-year-old smoker with a background history of a treated glottic carcinoma and chronic obstructive pulmonary disease presented with progressive hoarseness, symptoms of aspiration and shortness of breath for 6 months. Examination revealed an ulcero-fungating mass over the posterior commissure of the larynx. A tracheostomy, direct laryngoscopy and biopsy of the mass was performed to secure his airway and to exclude recurrent glottic carcinoma. Reassuringly, a histopathological examination of the mass revealed numerous fungal yeast bodies. He was then treated with itraconazole for 4 weeks and was followed up as and outpatient with complete resolution and no recurrence of the disease.

OBJECTIVES: Acute laryngitis is a common disease with self-limiting nature. Since the leading cause is attributed to viral infections and thus self-limiting, many affected individuals do not seek professional medical help. However, because the major symptom of hoarseness imposes a substantial burden in everyday life, it might be speculated that web-based search interest on this condition follows incidence rates, with highest peaks during winter months. The aim of this study was to evaluate global public health-information seeking behaviour on laryngitis-related search terms. METHODS: We utilized Google Trends to assess country-specific, representative laryngitis-related search terms for English and non-English speaking countries of both hemispheres. Extracted time series data from Australia, Brazil, Canada, Germany, the United Kingdom, and the United States of America, covering a timeframe between 2004 and 2019 were first assessed for reliability, followed by seasonality analysis using the cosinor model. RESULTS: Direct comparisons revealed different, representative laryngitis-related search terms for English- and non-English speaking countries. Extracted data showed a trend of higher reliability in countries with more inhabitants. Subsequent graphical analysis revealed winter peaks in all countries from both hemispheres. Cosinor analysis confirmed these seasonal variations to be significant (all P < 0.001). CONCLUSION: Public interest in laryngitis-related, online health information displayed seasonal variations in countries from both hemispheres, with highest interest during winter months. These findings emphasize the importance to optimize the distribution of reliable, web-based health education in order to prevent the spread of misinformation and to improve health literacy among general populations.

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.
