Laryngopharyngeal reflux disease: Updated examination of mechanisms, pathophysiology, treatment, and association with gastroesophageal reflux disease. World J Gastroenterol 2024; 30:2209-2219. [PMID: 38690022 PMCID: PMC11056915 DOI: 10.3748/wjg.v30.i16.2209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 02/02/2024] [Accepted: 03/29/2024] [Indexed: 04/26/2024] Open
Abstract
Laryngopharyngeal reflux disease (LPRD) is an inflammatory condition in the laryngopharynx and upper aerodigestive tract mucosa caused by reflux of stomach contents beyond the esophagus. LPRD commonly presents with sym-ptoms such as hoarseness, cough, sore throat, a feeling of throat obstruction, excessive throat mucus. This complex condition is thought to involve both reflux and reflex mechanisms, but a clear understanding of its molecular mechanisms is still lacking. Currently, there is no standardized diagnosis or treatment protocol. Therapeutic strategies for LPRD mainly include lifestyle modifications, proton pump inhibitors and endoscopic surgery. This paper seeks to provide a comprehensive overview of the existing literature regarding the mechanisms, patho-physiology and treatment of LPRD. We also provide an in-depth exploration of the association between LPRD and gastroesophageal reflux disease.

Cryptococcal laryngitis in an immunocompetent asthmatic patient using inhaled corticosteroids. Med Mycol Case Rep 2023; 42:100599. [PMID: 37727452 PMCID: PMC10506085 DOI: 10.1016/j.mmcr.2023.08.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2023] [Revised: 08/07/2023] [Accepted: 08/15/2023] [Indexed: 09/21/2023] Open
Abstract
We present a case of laryngeal cryptococcosis caused by cryptococcosis neoformans var. grubii affecting a patient using excessive inhaled corticosteroids. The patient experienced symptoms for several months prior to specialist review and the visualization of a mass lesion by nasopharyngoscopy. Fortunately a biopsy was performed and through histopathology & microbiological assessment a diagnosis of cryptococcal laryngitis was made. Treatment with 6 months of fluconazole resulted in clinical cure and resolution of symptoms. It is important to raise awareness of the risk of non-Candida fungal infections in patients on high dose corticosteroids, especially in the post covid era were steroids are more commonly prescribed.

Abstract
Breathing disorders in children are one of the most common challenges for both parents and physicians. The first step should always consist of the initial clinical assessment concerning the potentially critically ill patient. Using the pediatric assessment triangle (PAT), the rapid evaluation of airway and breathing is crucial. Although the etiology of pediatric breathing disorders is manifold, we would like to focus on common diagnoses. Based on the three leading symptoms stridor, wheeze, and tachypnea, the most important diseases of pediatric patients are presented and initial treatment steps are discussed. We target crucial, life-saving, basic medical procedures that should be mastered and performed in and also outside of specialized centers or pediatric units.

COVID-19 Omicron variant-induced laryngitis. Auris Nasus Larynx 2023; 50:637-640. [PMID: 36114072 PMCID: PMC9395289 DOI: 10.1016/j.anl.2022.08.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Revised: 07/20/2022] [Accepted: 08/17/2022] [Indexed: 11/29/2022]
Abstract
OBJECTIVES The COVID-19 omicron variant has a low affinity for the lower respiratory tract. However, upper respiratory tract symptoms, such as nasal discharge and sore throat, characterize the infection with this variant. Therefore, in laryngeal stenosis, disease severity assessment through blood oxygen saturation has not been useful. METHODS We report the case of "omicron laryngitis" in a 59-year-old male who visited the ear, nose, and throat (ENT) clinic with complaints of a sore throat and difficulty in swallowing saliva that persisted for a day. RESULTS Laryngoscopy revealed severe swelling of the transglottic region and exudates on the larynx. He was then diagnosed with COVID-19 and subjected to emergency tracheostomy for airway management. Until the emergence of the omicron variant, COVID-19 showed mainly lower airway and mild upper airway inflammatory features. However, upper airway stenosis should be suspected in cases presenting with "muffled speech," "dysphagia," "severe pain on swallowing," and "inspiratory dyspnea or stridor." CONCLUSION Therefore, laryngeal and pharyngeal evaluation using a flexible laryngoscope under appropriate infection control measures is necessary, considering the possibility of progression to fatal laryngeal stenosis, as noted in this case.

A systematic review and meta-analysis of neuromodulators to treat chronic airway hypersensitivity. Am J Otolaryngol 2023; 44:103815. [PMID: 36870112 DOI: 10.1016/j.amjoto.2023.103815] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Accepted: 02/19/2023] [Indexed: 03/03/2023]
Abstract
OBJECTIVES Chronic laryngitis can present with numerous symptoms, including chronic cough. Patients who do not respond to standard treatment are sometimes diagnosed with chronic airway hypersensitivity (CAH). In many centers, neuromodulators are prescribed off-label despite limited evidence of efficacy. A previous meta-analysis suggested neuromodulator therapy improved cough-related quality-of-life (QoL). This current updated and expanded meta-analysis examined whether neuromodulators reduced cough frequency, reduced cough severity, and/or improved QoL in CAH patients. DATA SOURCES PubMed, Embase, Medline, Cochrane Review, and publication bibliographies were searched from 01/01/2000 to 07/31/2021 using MESH terms. REVIEW METHODS PRISMA guidelines were followed. 999 abstracts were identified/screened, 28 studies were fully reviewed, and 3 met inclusion criteria. Only randomized controlled trials (RCT) investigating CAH patients with comparable cough-related outcomes were included. Three authors reviewed potentially eligible papers. Fixed-effect models and calculated pooled estimates using the Inverse-Variance method were used. RESULTS The estimated difference in change in log coughs per hour (from baseline to intervention end) between treatment and control groups was -0.46, 95%CI [-0.97; 0.05]. Estimated change-from-baseline in VAS scores was -12.24, 95 % CI [-17.84; -6.65] lower for patients who received treatment vs placebo. Estimated change-from-baseline for LCQ scores was 2.15, 95 % CI [1.49-2.80] higher for patients who receive treatment vs placebo. Only change in LCQ score was clinically significant. CONCLUSIONS This study tentatively suggests that neuromodulators have the potential to reduce cough symptoms associated with CAH. However, high-quality evidence is lacking. This could be due to limited treatment effect or significant limitations in the design and comparability of existing trials. A well-designed and properly powered RCT is needed to authoritatively test the efficacy of neuromodulators for the treatment of CAH. LEVEL OF EVIDENCE Level I, evidence from a systematic review or meta-analysis of all relevant RCTs (randomized controlled trial) or evidence-based clinical practice guidelines based on systematic reviews of RCTs or three or more RCTs of good quality that have similar results.

Laryngeal Mucous Membrane Pemphigoid as an Immune-related Adverse Effect of Pembrolizumab Treatment. J Voice 2023:S0892-1997(22)00429-5. [PMID: 36658034 DOI: 10.1016/j.jvoice.2022.12.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 12/28/2022] [Accepted: 12/29/2022] [Indexed: 01/20/2023]
Abstract
Pembrolizumab is an immune checkpoint inhibitor (ICI) approved for multiple indications in a variety of malignancies. Although generally well tolerated, the potential for significant adverse effects, specifically immune related adverse effects (irAEs) needs to be taken into consideration. Several cases of bullous pemphigoid have been reported as a cutaneous adverse effect of ICIs since 2015, and there are recent reports of mucous membrane pemphigoid (MMP). We present the case of an 84-year-old male with metastatic urothelial carcinoma on treatment with pembrolizumab, who developed laryngeal mucous membrane pemphigoid as an irAE. The diagnosis was based on patient's clinical history and serologic testing, and supported by symptomatic improvement after ICI discontinuation and immunosuppression. Pembrolizumab-induced MMP is a newly described and infrequent irAE, requiring early suspicion and close monitoring for its diagnosis and management.

Abstract
A 43-year-old woman was found to have active post-primary tuberculosis and a lateral neck radiograph showing a thickened epiglottis. Bronchoscopy-guided biopsies of the epiglottis and lung were acid fast bacilli stain positive. Histopathology from both showed multiple caseating granulomas. The patient's condition improved with RIPE therapy. This case illustrates the importance for physicians to be aware of possible laryngeal involvement in tuberculosis and that it can present even without evidence of active or latent tuberculosis.

Abstract
OBJECTIVES Infection with herpes simplex virus (HSV) typically causes limited oral and genital symptoms, however HSV can also affect the larynx and result in severe aerodigestive symptoms. Due to the rarity of HSV laryngitis, the symptoms and clinical course of are not well understood. This study aims to more completely characterize HSV laryngitis in order to aid clinicians in understanding and recognition of HSV laryngitis. METHODS Comprehensive literature search of MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews to identify articles relating to HSV laryngitis. Patient demographics, presenting signs and symptoms, treatment and clinical course were extracted from the selected manuscripts. RESULTS There were 31 studies on HSV laryngitis that identified 36 patients (17 pediatric, 19 adult). The average age for pediatric patients was 11 months (9 M, 8F) and 52 years for adults (11 M, 8F). In the pediatric population, stridor was more common at presentation in comparison to the adult population (p < .01). Adults more commonly presented with dysphagia (p = .03) and dysphonia (p < .01) Adult patients were significantly more likely to undergo tracheotomy than pediatric patients (p = .047). The mean length of inpatient hospital stay was 21.2 days in pediatric patients and 15.8 days for adult patients. CONCLUSION HSV laryngitis has a unique presentation in pediatrics and adults, but is nonspecific in both populations leading to delays in diagnosis and treatment. HSV laryngitis is associated with significant morbidity including multi-week hospital stay and risk for needing tracheostomy in both adults and pediatric population which demonstrates need for clinical awareness of this complication of HSV infection.

Impact of subspecialty training on management of laryngopharyngeal reflux: results of a worldwide survey. Eur Arch Otorhinolaryngol 2021; 278:1933-1943. [PMID: 33638681 DOI: 10.1007/s00405-021-06710-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Accepted: 02/18/2021] [Indexed: 12/21/2022]
Abstract
OBJECTIVE To study the management of laryngopharyngeal reflux (LPR) among the subspecialties of practicing otolaryngology-head and neck surgeons and their trainees. METHODS A survey was sent to over 8000 otolaryngologists (OTOHNS) over 65 countries, utilizing membership lists of participating otolaryngological societies. The outcomes were answers to questions regarding LPR knowledge and practice patterns, and included queries about its definition, prevalence, clinical presentation, diagnosis, and treatment. RESULTS Of the 824 respondents, 658 practiced in one specific otolaryngologic subspecialty. The symptoms and findings thought to be the most related to LPR varied significantly between subspecialists. Extra-laryngeal findings were considered less by laryngologists while more experienced OTOHNS did not often consider digestive complaints. Compared with colleagues, otologists, rhinologists and laryngologists were less aware of the involvement of LPR in otological, rhinological and laryngological disorders, respectively. Irrespective of subspecialty, OTOHNS consider symptoms and signs and a positive response to empirical therapeutic trial to establish a LPR diagnosis. Awareness regarding the usefulness of impedance pH-studies is low in all groups. The therapeutic approach significantly varies between groups, although all were in agreement for the treatment duration. The management of non-responder patients demonstrated significant differences among laryngologists who performed additional examinations. The majority of participants (37.1%) admitted to being less than knowledgeable about LPR management. CONCLUSIONS LPR knowledge and management vary significantly across otolaryngology subspecialties. International guidelines on LPR management appear necessary to improve knowledge and management of LPR across all subspecialties of otolaryngology.

Abstract
Background A national consensus document on inhaled corticosteroids (ICS) use in childhood, produced by the main Italian pediatric scientific societies, has been recently released. The aim of this study was to gather information on the current pediatricians’ ICS prescription habits in Italy for the management of the most common pediatric respiratory diseases, namely allergic rhinitis (AR), asthma, preschool wheezing and laryngitis. Methods From the 1st October 2018 to the 31st January 2019 a link to an online questionnaire was sent monthly through a newsletter to the members of the Italian Society of Pediatrics. The questionnaire included 18 items on ICS use in the most common pediatric respiratory diseases. Data collection and reporting was based on STROBE Statement Checklist for cross-sectional studies. Results One thousand-two questionnaires were returned from primary care pediatricians (39.1%), hospital pediatricians (38.7%), private practicers (16.4%), university pediatricians (3.1%) and Pediatrics residents (2.7%). We found a good adherence to the international guidelines on AR, with prevalent use of oral antihistamine (60.6%) in the secretive phenotype and nasal ICS in the obstructive phenotype (64.8%). In asthma exacerbations ICS are not used in 53.4% of cases, but they are used at high dose in 27.9% and at low dose in 18.7% of cases. In intermittent asthma, ICS are not chosen as a daily controller therapy in 54.1% of cases, while they are chosen as a low dose daily therapy in 44.5% of cases (high dose in 1.4%). In children with persistent asthma, ICS are chosen as a daily low dose therapy in 67.4% of cases and as a daily high dose therapy in 31%. In the management of preschool wheezing, when a long-term treatment is needed, ICS are chosen both alone and in association with antileukotrienes in 71.4% of cases. Children affected by recurrent asthma exacerbations and wheezing are closely followed up, in particular by their primary care pediatricians. The preference for certain molecules in the treatment of different respiratory diseases also emerged. Conclusions Pediatricians’ ICS prescription habits in Italy should be improved, especially in the management of asthma. Future surveys on a more numerous sample will be useful to analyze differences in prescription habits on the basis of pediatricians’ work settings and geographical distribution.

Abstract
Supraglottitis is a life-threatening, predominantly bacterial disease that is rarely caused by viral etiologies. Herpes Simplex Virus (HSV) supraglottitis has been infrequently reported, but its presentation can mimic that of bacterial supraglottitis or pharyngitis which may lead to delayed diagnosis and increased morbidity. We present a case of supraglottitis in an immunocompetent man initially thought to have bacterial epiglottitis. After receiving a tracheostomy due to impending airway compromise and failing to improve on antibiotic therapy, biopsy of the upper airway tissue revealed infection with HSV type 2. The patient improved after multiple weeks of systemic antivirals. HSV supraglottitis remains an unusual but important diagnostic consideration in patients with dysphonia, dysphagia, ulcerative supraglottal lesions, and acute supraglottic inflammation unresponsive to antibiotics.

Abstract
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.

Abstract
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.

Abstract
PURPOSE OF REVIEW Allergic rhinitis and allergic asthma are well-described disease entities with broad exposure in clinical and research allergy forums. Associations between allergic inflammation and upper airway diseases of chronic laryngitis, otitis media, obstructive sleep apnea, and oral allergy syndrome are less well understood and described in the literature. RECENT FINDINGS This review discusses the relationship between atopy and diseases of the upper airway, oral cavity, larynx, and ear. The similar respiratory mucosal lining the upper aerodigestive tract, with sensitized mast cells and inflammatory mediators in the submucosa, results in a variety of extranasal manifestations of allergic diseases in the head and neck which are less well characterized. Associations between allergic inflammation and upper airway diseases of chronic laryngitis, otitis media, obstructive sleep apnea, and oral allergy syndrome are less well understood and described in the literature. This review will summarize the relevant pathophysiology and symptomology, association with allergic sensitization, and clinical considerations of these disorders.

Abstract
BACKGROUND Croup is a common respiratory illness in children. It presents with a barky cough, stridor and hoarseness occurring secondary to inflammation of the subglottis and larynx. The clinical course of croup is well-described, however atypical presentations pose a diagnostic and management challenge. OBJECTIVES This case report and systematic review aims to synthesize the published literature on the definition, diagnosis and treatment of atypical croup. STUDY SELECTION Peer-reviewed journal publications in Ovid MEDLINE® and EMBASE from inception to January 1, 2019 in English, focusing on pediatric patients (<18 years of age) with diagnoses of atypical croup. DATA EXTRACTION Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS Twelve studies involving 670 patients ranging from 6 months to 11 years of age presenting with atypical croup were selected. A variety of definitions of atypical croup were identified based on recurrence, duration of symptoms, severity, and etiology. Data on the incidence of atypical croup, the overall rates of intubation and tracheostomy, and patient characteristics leading to definitive airway management were not clearly characterized. LIMITATIONS All studies were case series, case reports or retrospective chart reviews. CONCLUSIONS Atypical croup is a poorly defined clinical entity that is used to describe recurrent, refractory, or croup-like illness that follows an uncharacteristic natural history. Our case presentation and accompanying literature review highlights the variable, but limited, information available on the diagnosis of atypical croup. Given the commonality of its use in clinical practice, we propose some guidelines around the use of the term 'atypical croup' as well as a management algorithm.

Abstract
Isolated laryngeal Leishmaniasis is a rare entity in the Indian subcontinent. We describe a case of a 45 year old male with hoarseness and noisy breathing. Patient's initial histological and serological workup was inconclusive. Final biopsy findings (suggestive of Leishmania donovani), positive rK-39 serology and his native place being Bihar (endemic for Leishmaniasis) led us to the diagnosis. He was treated with high dose liposomal Amphotericin B to which he responded well. This case report highlights the importance of remaining aware of rare infectious causes of laryngitis. Timely diagnosis and intervention are crucial.

Treatment of laryngopharyngeal reflux disease: A systematic review. World J Clin Cases 2019; 7:2995-3011. [PMID: 31624747 PMCID: PMC6795731 DOI: 10.12998/wjcc.v7.i19.2995] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 09/05/2019] [Accepted: 09/11/2019] [Indexed: 02/05/2023] Open
Abstract
BACKGROUNG For a long time, laryngopharyngeal reflux disease (LPRD) has been treated by proton pump inhibitors (PPIs) with an uncertain success rate.
AIM To shed light the current therapeutic strategies used for LPRD in order to analysis the rationale in the LPRD treatment.
METHODS Three authors conducted a PubMed search to identify papers published between January 1990 and February 2019 about the treatment of LPRD. Clinical prospective or retrospective studies had to explore the impact of medical treatment(s) on the clinical presentation of suspected or confirmed LPRD. The criteria for considering studies for the review were based on the population, intervention, comparison, and outcome framework.
RESULTS The search identified 1355 relevant papers, of which 76 studies met the inclusion criteria, accounting for 6457 patients. A total of 64 studies consisted of empirical therapeutic trials and 12 were studies where authors formally identified LPRD with pH-monitoring or multichannel intraluminal impedance-pH monitoring (MII-pH). The main therapeutic scheme consisted of once or twice daily PPIs for a duration ranged from 4 to 24 wk. The most used PPIs were omeprazole, esomeprazole, rabeprazole, lansoprazole and pantoprazole with a success rate ranging from 18% to 87%. Other composite treatments have been prescribed including PPIs, alginate, prokinetics, and H2 Receptor antagonists.
CONCLUSION Regarding the development of MII-pH and the identification of LPRD subtypes (acid, nonacid, mixed), future studies are needed to improve the LPRD treatment considering all subtypes of reflux.

Abstract
OBJECTIVE To develop clinical tools assessing the refluxogenic potential of foods and beverages (F&B) consumed by patients with laryngopharyngeal reflux (LPR). METHODS European experts of the LPR Study group of the Young-Otolaryngologists of the International Federation of Oto-rhino-laryngological societies were invited to identify the components of Western European F&B that would be associated with the development of LPR. Based on the list generated by experts, four authors conducted a systematic review to identify the F&B involved in the development of esophageal sphincter and motility dysfunctions, both mechanisms involved in the development of gastroesophageal reflux disease and LPR. Regarding the F&B components and the characteristics identified as important in the development of reflux, experts developed three rational scores for the assessment of the refluxogenic potential of F&B, a dish, or the overall diet of the patient. RESULTS Twenty-six European experts participated to the study and identified the following components of F&B as important in the development of LPR: pH; lipid, carbohydrate, protein composition; fiber composition of vegetables; alcohol degree; caffeine/theine composition; and high osmolality of beverage. A total of 72 relevant studies have contributed to identifying the Western European F&B that are highly susceptible to be involved in the development of reflux. The F&B characteristics were considered for developing a Refluxogenic Diet Score (REDS), allowing a categorization of F&B into five categories ranging from 1 (low refluxogenic F&B) to 5 (high refluxogenic F&B). From REDS, experts developed the Refluxogenic Score of a Dish (RESDI) and the Global Refluxogenic Diet Score (GRES), which allow the assessment of the refluxogenic potential of dish and the overall diet of the LPR patient, respectively. CONCLUSION REDS, RESDI and GRES are proposed as objective scores for assessing the refluxogenic potential of F&B composing a dish or the overall diet of LPR patients. Future studies are needed to study the correlation between these scores and the development of LPR according to impedance-pH study.

Abstract
Dysphonia is altered voice quality, pitch, loudness, or vocal effort that impairs communication or decreases voice-related quality of life. Hoarseness is vocal roughness and a possible manifestation of dysphonia. This article uses the broader term dysphonia because it reflects of a wide range of voice complaints, with or without vocal roughness. Dysphonia is often caused by benign conditions but may also be the sentinel symptom of a serious or progressive condition requiring immediate diagnosis and management. The role of laryngeal visualization in assessment and diagnosis for these patients is critical.

Abstract
Systemic diseases commonly managed by the Internist may have presentations within the head and neck. Awareness of these manifestations, sometimes as the presenting signs or symptoms of systemic disease, may aid the Internist in diagnosis and management. The Otolaryngologist may be helpful in assisting in the evaluation of these patients and in some cases providing targeted symptomatic therapy. Some systemic processes can generate emergent airway events, and early engagement of the otolaryngologist is of value.

Abstract
IgG4-related disease is characterized by a lymphoplasmacytic infiltrate rich in IgG4-positive plasma cells, storiform fibrosis and obliterative phlebitis. It can present as parotid gland enlargement, tubulointerstitial nephritis, retroperitoneal fibrosis or pancreatitis, although nearly any organ can be affected. We report the case of a 37-year-old woman who presented with severe dysphonia and recurrent painful aphthous ulcers, with histopathological findings at the level of the larynx that revealed a lymphoplasmacytic infiltrate and IgG4 positivity. In addition, extensive studies were performed to rule out other diseases. Thus the diagnosis was IgG4-related laryngitis, an exceptional finding in the literature.

Revealing the needs of children with tracheostomies. Eur Ann Otorhinolaryngol Head Neck Dis 2018; 135:S93-S97. [PMID: 30193946 DOI: 10.1016/j.anorl.2018.07.007] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2018] [Revised: 07/27/2018] [Accepted: 07/27/2018] [Indexed: 10/28/2022]
Abstract
INTRODUCTION Small children with tracheostomy are at potential risk and have very specific needs. International literature describes the need for tracheostomy in 0.5% to 2% of children following intubation. Reports of children submitted to tracheostomy, their characteristics and needs are limited in developing countries and therefore there is a lack of health programs and government investment directed to medical and non-medical care of these patients. The aim of this study was to describe the characteristics of these children and identify problems related to or caused by the tracheostomy. METHODS A retrospective cohort study was performed based on a common database applied in four high complexity healthcare facilities to children submitted to tracheostomy from January 2013 to December 2015. Data concerning children's demographics, indication for tracheostomy, early and late complications related to tracheostomy, airway diagnosis, comorbidities and decannulation rates are reported. Patients who did not present a complete database or had a follow-up of less than six months were excluded. RESULTS A total of 160 children submitted to tracheostomy during the three-year period met the criteria and were enrolled in this study. Median age at tracheostomy was 6.9 months (ranging from 1 month to 16 years, interquartile range of 26 months). Post-intubation laryngitis was the most frequent indication (48.8%). Comorbidities were frequent: neurologic disorders were reported in 40%, pulmonary pathologies in 26.9% and 20% were premature infants. Syndromic children were 23.1% and the most frequent was Down's syndrome. The most common early complication was infection that occurred in 8.1%. Stomal granulomas were the most frequent late complication and occurred in 16.9%. Airway anomalies were frequently diagnosed in follow-up endoscopic evaluations. Subglottic stenosis was the most frequent airway diagnosis and occurred in 29.4% of the cases followed by laryngomalacia, suprastomal collapse and vocal cord paralysis. Decannulation was achieved in 22.5% of the cases in the three-year period. The main cause for persistent tracheostomy was the need for further treatment of airway pathology. Mortality rate was 18.1% during this period but only 1.3% were directly related to the tracheostomy, the other deaths were a consequence of other comorbidities. CONCLUSION Tracheostomies were performed mostly in very small children and comorbidities were very common. Once a tracheostomy was performed in a child in most cases it was not removed before a year. The most common early complication was stoma infection followed by accidental decannulation. The most frequent late complication was granuloma and suprastomal collapse. Airway abnormalities were very frequent in this population and therefore need to be assessed before attempting decannulation.

Abstract
OBJECTIVES Ulcerative laryngitis (UL) is challenging in terms of treatment and patient counseling, with few reports in the literature. This study describes UL patients and their clinical course including detailed voice and stroboscopic outcomes after treatment which have not been described in previous literature. METHODS Single-institution, retrospective review of 23 UL patients. Demographics, historical factors, disease course, treatment, and outcomes are presented. Treatment results were compared to prior studies. RESULTS Seventy four percent had inflammatory/infectious precipitating event. Average presenting Voice-Handicap-Index-10 (VHI-10) was 25 (range: 6-38) and average final VHI-10 was 9 (range: 0-26). Ninty five percent had improvement in VHI-10 (average decrease of 15). Only 50% had final VHI-10 within "normal" limits. Treatment comprised reflux medications (85%), antibiotics (22%), antifungals (39%), antivirals (52%) steroids (52%), and/or voice rest (65%). Average symptom duration before evaluation was 42 days; average follow-up was 6.8 months. Final laryngovideostroboscopy revealed no ulcers in 78%, but 65% had persistently decreased mucosal wave vibration. Average time to ulcer resolution was 2.25 months but resolution or plateau of voice symptoms occurred later, average 2.7 months. Multiple regression analyses revealed that younger age, shorter symptom duration, and antireflux treatment were significant predictors of decrease in VHI-10 (P < 0.05). CONCLUSIONS Most patients have good voice outcomes following resolution of UL, although vocal fold mucosal wave abnormalities may persist. This study provides the most detailed report of UL, disease course and treatment outcomes to date. Additionally, this study is also the first to suggest that earlier initiation of treatment may improve voice outcome after UL.

Abstract
Cryptococcus neoformans is a yeast than can result in isolated or disseminated infections. This case report describes an immunocompetent patient presenting with airway obstruction secondary to laryngeal crypotococcoma, mimicking a laryngeal malignancy, and describes associated management. A 68-year-old immunocompetent female with a new positron emission tomography-avid laryngeal lesion was intubated after acute respiratory decompensation. Airway evaluation revealed diffuse mucosal changes throughout the endolarynx with significant loss of normal native tissue architecture. Operative biopsy confirmed infection of C neoformans. The patient was treated with extended-course fluconazole. This case reinforces characteristic physical and histologic findings described for laryngeal cryptococcal infection.

Abstract
BACKGROUND Allergies are among the most common chronic conditions worldwide affecting 10%-30% of adult individuals and 40% of children. Phonation can be affected by different allergic conditions in various ways. The role of allergy in phonation has been under-researched and poorly understood and the respective literature is poor. Several studies have investigated the role of certain allergic diseases in phonation. In this review, we tried to include all allergic conditions that can affect voice production. METHODS We conducted a bibliography review looking for allergic conditions that can affect phonation. Allergic asthma, allergic laryngitis, allergic rhinitis and sinusitis, oral allergy syndrome, and angioedema were included in our search. RESULTS The literature on the impact of allergy in phonation remains poor and many key questions concerning basic information for epidemiology, pathophysiology, and larynx pathology in allergic patients with phonation problems still remain unanswered. CONCLUSIONS The role of allergy in voice production remains underinvestigated and many basic questions still remain open. Further research is needed to improve our understanding for these very common conditions.

Extraesophageal Symptoms and Diseases Attributed to GERD: Where is the Pendulum Swinging Now? Clin Gastroenterol Hepatol 2018; 16:1018-1029.

Abstract
The purpose of this review is to outline the recent developments in the field of extraesophageal reflux disease and provide clinically relevant recommendations. The recommendations outlined in this review are based on expert opinion and on relevant publications from PubMed and EMbase. The Clinical Practice Updates Committee of the American Gastroenterological Association proposes the following recommendations: Best Practice Advice 1: The role of a gastroenterologist in patients referred for evaluation of suspected extra esophageal symptom is to assess for gastroesophageal etiologies that could contribute to the presenting symptoms. Best Practice Advice 2: Non-GI evaluations by ENT, pulmonary and/or allergy are essential and often should be performed initially in most patients as the cause of the extraesophageal symptom is commonly multifactorial or not esophageal in origin. Best Practice Advice 3: Empiric therapy with aggressive acid suppression for 6-8 weeks with special focus on response of the extraesophageal symptoms can help in assessing association between reflux and extraesophageal symptoms. Best Practice Advice 4: No single testing methodology exists to definitively identify reflux as the etiology for the suspected extra esophageal symptoms. Best Practice Advice 5: Constellation of patient presentation, diagnostic test results and response to therapy should be employed in the determination of reflux as a possible etiology in extra esophageal symptoms. Best Practice Advice 6: Testing may need to be off or on proton pump inhibitor (PPI) therapy depending on patients' presenting demographics and symptoms in assessing the likelihood of abnormal gastroesophageal reflux. A. On therapy testing may be considered in those with high probability of baseline reflux (those with previous esophagitis, Barrett's esophagus or abnormal pH). B. Off therapy testing may be considered in those with low probability of baseline reflux with the goal of identifying moderate to severe reflux at baseline. Best Practice Advice 7: Lack of response to aggressive acid suppressive therapy combined with normal pH testing off therapy or impedance-pH testing on therapy significantly reduces the likelihood that reflux is a contributing etiology in presenting extraesophageal symptoms. Best Practice Advice 8: Surgical fundoplication is discouraged in those with extra esophageal reflux symptoms unresponsive to aggressive PPI therapy. Best Practice Advice 9: Fundoplication should only be considered in those with a mechanical defect (e.g., hiatal hernia), moderate to severe reflux at baseline off PPI therapy who have continued reflux despite PPI therapy and have failed more conservative non-GI treatments.

Abstract
BACKGROUND Eosinophilic granulomatosis with polyangiitis and granulomatosis with polyangiitis show variable otorhinolaryngological involvement. Up to 14 per cent of granulomatosis with polyangiitis patients have subglottis involvement; little is known about the laryngeal involvement in eosinophilic granulomatosis with polyangiitis. METHOD A literature review was conducted, together with a prospective cross-sectional analysis of 43 eosinophilic granulomatosis with polyangiitis patients. All patients underwent fibre-optic laryngoscopy with narrow-band imaging, and completed health-related questionnaires. RESULTS The literature review showed only two cases of laryngeal involvement in eosinophilic granulomatosis with polyangiitis; in our cohort, no cases of subglottis stenosis were found, but local signs of laryngeal inflammation were present in 72 per cent of cases. Of the patients, 16.2 per cent had a pathological Reflux Finding Score (of 7 or higher). CONCLUSION Laryngeal inflammation in eosinophilic granulomatosis with polyangiitis is frequent. It is possibly due more to local factors than to eosinophilic granulomatosis with polyangiitis itself. However, ENT evaluation is needed to rule out possible subglottis inflammation. These findings are in line with current literature and worthy of confirmation in larger cohorts.

Abstract
OBJECTIVE A neuropathic etiology has been suggested for patients with chronic laryngopharyngitis symptoms without visible structural pathology. Prior studies have shown that treatment with neuro-modulating medications is beneficial, but it is unknown if this was due to placebo effect. Our objective was to compare the efficacy of amitriptyline versus placebo in treating chronic laryngopharyngeal neuropathy. STUDY DESIGN Prospective, randomized placebo-controlled trial. METHODS Patients were randomized to receive placebo or amitriptyline for 8weeks. Primary outcome was change in modified Reflux Symptom Index (mRSI) score. Secondary outcomes were change in Voice Handicap Index-10 (VHI) scores, rates of adverse effects, and overall symptom severity. RESULTS Eighteen patients completed the study. The average difference in mRSI and VHI-10 scores after treatment were not significantly different between study arms. However, more subjects taking amitriptyline felt their symptoms had subjectively improved (6 out of 9, 67%), while the remainder noted no change. In the placebo group, only 4 out of 9 subjects (44%) felt their symptoms were better and 2 felt worse. Subjects took an average of 25mg of amitriptyline or placebo daily by the end of the 8-week treatment period. No serious adverse effects were noted. CONCLUSION Although there was a trend toward greater subjective improvement in overall symptoms with amitriptyline, interpretation is limited due to the small sample size. Larger randomized controlled trials to determine the efficacy of neuro-modulating agents in the treatment of chronic laryngopharyngeal neuropathy, as well as better metrics to characterize this disorder, are warranted.

Abstract
The upper and lower airways are linked epidemiologically and pathophysiologically. The upper and lower airways are considered a single, functional unit characterized by shared immunologic mechanisms, often referred to as the unified airway. Upper and lower airway inflammatory disease frequently coexist in the same patient. Allergic rhinitis and rhinosinusitis are associated with asthma. Treatment of both diseases impacts asthma outcomes. The otolaryngologist may be the first physician to suspect and diagnose asthma in patients with upper airway complaints. A thorough understanding of the relationship between allergic rhinitis, rhinosinusitis, and asthma will facilitate early identification of asthma and improve patient outcomes.

Abstract
Classic gastroenterological diagnostic tools have proven to be insufficient in identifying the causal relationship between extra-esophageal symptoms and presumed pathological reflux activity. Some new methodological approaches, such as functional endoscopy (video panendoscopy, VPE), are considered to be helpful. However, there are currently no data objectively verifying the success of this method. In a previous study, we found a good correlation between the reflux symptom index (RSI) according to Belafsky and endoscopic findings. Impedance-pH measurement is considered to be the gold standard in esophageal reflux disease diagnostics. Therefore, the relationship between endoscopic findings and the results of impedance-pH monitoring is now studied in patients with extra-esophageal reflux symptoms. The pathological findings of the VPE correlate with impedance-pH measurements regarding the parameters "number of reflux episodes," "fraction time," and "DeMeester score."

Abstract
Classic gastroenterological diagnostic tools are proving increasingly insufficient for analyzing the complex causal relationship between extra-esophageal symptoms and presumed pathological reflux activity. Some new methodological approaches, such as functional endoscopy (videopanendoscopy, VPE), are considered to be helpful. However, there are currently no data objectively verifying the usefulness of this method. In a pilot study, a good correlation between the reflux symptom index (RSI) and endoscopic findings was shown. Impedance-pH measurement is considered to be the "gold standard" in esophageal reflux disease diagnostics. Therefore, the relationship between endoscopic findings and the results of impedance-pH monitoring are now studied in patients with extra-esophageal reflux symptoms. The investigation demonstrates that the pathological findings of VPE correlate well with impedance-pH measurements in terms of the parameters "number of reflux episodes", "fraction time", and "DeMeester score".

Abstract
OBJECTIVE This report describes the clinical presentation and management of a rare case of herpes simplex virus infection in the larynx of a patient treated with methotrexate. CASE REPORT We report a case of a clinically suspicious laryngeal lesion in an 82-year-old woman who started methotrexate treatment for rheumatoid arthritis. Shortly afterwards she developed dysphonia, which worsened over four months. On microlaryngoscopy, there was bilateral erythema and ulceration of the vocal folds. No other mucocutaneous lesions or systemic features were present. Biopsies revealed herpes simplex virus infection of the vocal folds; there was complete resolution with oral aciclovir. A brief literature review for this rare entity is presented and the diagnostic challenges arising from under-recognition of atypical presentations are discussed. CONCLUSION To our knowledge, this is the first report of a rare complication of herpes simplex virus infection in the context of methotrexate-induced immunosuppression. It may present therapeutic challenges for conditions which rely on immunosuppressive treatments.

Abstract
Ramsay Hunt syndrome is characterized by varicella zoster virus infection affecting the geniculate ganglion of the facial nerve. It typically presents with vesicles in the external auditory canal associated with auricular pain and peripheral facial nerve paralysis. Although vestibulocochlear nerve is frequently co-involved during the course of Ramsay Hunt syndrome, multiple lower cranial nerve involvement has rarely been described in the literature. In addition, laryngitis due to varicella zoster virus is a diagnostic challenge due to its unfamiliarity among clinicians. We report a case of Ramsay Hunt syndrome with laryngitis involving multiple lower cranial nerves.

Abstract
UNLABELLED Evidence-based guidelines are needed to harmonise and improve the diagnostics and treatment of children's lower respiratory tract infections. Following a professional literature search, an interdisciplinary working group evaluated and graded the available evidence and constructed guidelines for treating laryngitis, bronchitis, wheezing bronchitis and bronchiolitis. CONCLUSION Currently available drugs were not effective in relieving cough symptoms. Salbutamol inhalations could relieve the symptoms of wheezing bronchitis and should be administered via a holding chamber. Nebulised adrenaline or inhaled or oral glucocorticoids did not reduce hospitalisation rates or relieve symptoms in infants with bronchiolitis and should not be routinely used.

Supraesophageal Reflux: Correlation of Position and Occurrence of Acid Reflux-Effect of Head-of-Bed Elevation on Supine Reflux. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2015; 3:356-61. [PMID: 25609349 DOI: 10.1016/j.jaip.2014.11.019] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 04/08/2014] [Revised: 11/08/2014] [Accepted: 11/10/2014] [Indexed: 12/11/2022]
Abstract
BACKGROUND Supraesophageal reflux of gastric contents can contribute to perennial nasopharyngitis, cough, and asthma. However, effective treatment strategies for supraesophageal reflux disease (SERD) remain inadequately defined. OBJECTIVE The purpose of this study is to assess the prevalence and timing of SERD and to investigate the efficacy of head-of-bed elevation in its treatment. METHODS A retrospective chart review of patients seen at Scripps Clinic Division of Allergy, Asthma and Immunology was performed who had undergone overnight nasopharyngeal pH monitoring with a commercially available nasopharyngeal pH-monitoring device, Dx-pH Measurement System from Restech, San Diego, Calif. Subjects with reflux were classified based on the position of reflux as either supine only, upright only, or both supine and upright. In a subset of subjects with supine-only reflux, pH monitoring was compared before and after elevating the head of bed 6 inches. RESULTS Adequate nasopharyngeal pH-monitoring data were obtained for 235 patients. Reflux was detected in 113 (48%) patients. The pattern of reflux observed was 62 (55%) supine only, 4 (4%) upright only, and 47 (42%) upright and supine. Sequential overnight nasopharyngeal pH monitoring before and after head-of-bed elevation was obtained in 13 individuals with supine-only reflux. Ten subjects demonstrated significant improvement, 8 of whom demonstrated complete resolution of supine reflux with 6 inches of head-of-bed elevation. CONCLUSION This study provides new evidence that SERD frequently occurs in the supine position and that 6 inches of head-of-bed elevation is effective in reducing supine SERD.

Abstract
This article reviews the evaluation and management of patients with suspected extraesophageal manifestations of gastroesophageal reflux disease, such as asthma, chronic cough, and laryngitis, which are commonly encountered in gastroenterology practices. Otolaryngologists and gastroenterologists commonly disagree upon the underlying cause for complaints in patients with one of the suspected extraesophageal reflux syndromes. The accuracy of diagnostic tests (laryngoscopy, endoscopy, and pH- or pH-impedance monitoring) for patients with suspected extraesophageal manifestations of gastroesophageal reflux disease is suboptimal. An empiric trial of proton pump inhibitors in patients without alarm features can help some patients, but the response to therapy is variable.

Detection of chronic laryngitis due to laryngopharyngeal reflux using color and texture analysis of laryngoscopic images. J Voice 2013; 28:98-105. [PMID: 24314831 DOI: 10.1016/j.jvoice.2013.08.015] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2013] [Accepted: 08/26/2013] [Indexed: 11/20/2022]
Abstract
OBJECTIVE To determine if pattern recognition of hue and textural parameters can be used to identify laryngopharyngeal reflux (LPR). METHODS Laryngoscopic images from 20 subjects with LPR and 42 control subjects without LPR were obtained. LPR status was determined using the reflux finding score. Color and texture features were quantified using hue calculation and two-dimensional Gabor filtering. Five regions were analyzed: true vocal folds, false vocal folds, epiglottis, interarytenoid space, and arytenoid mucosae. A multilayer perceptron artificial neural network with varying numbers of hidden nodes was used to classify images according to pattern recognition. Receiver operating characteristic (ROC) analysis was used to evaluate diagnostic utility, and intraclass correlation coefficient analysis was performed to determine interrater reliability. RESULTS Classification accuracy when including all parameters was 80.5% ± 1.2% with an area under the ROC curve of 0.887. Classification accuracy decreased when including only hue (73.1% ± 3.5%; area under the curve = 0.834) or texture (74.9% ± 3.6%; area under the curve = 0.852) parameters. Interrater reliability was 0.97 ± 0.03 for hue parameters and 0.85 ± 0.11 for texture parameters. CONCLUSIONS This preliminary study suggests that a combination of hue and texture features can be used to detect chronic laryngitis due to LPR. A simple, minimally invasive assessment would be a valuable addition to the currently invasive and somewhat unreliable methods currently used for diagnosis. Including more data will likely improve classification accuracy. Additional investigations will be performed to determine if results are in accordance with those provided by pH probe monitoring.

Fungal laryngitis in immunocompetent patients. Indian J Otolaryngol Head Neck Surg 2011; 66:375-8. [PMID: 24533421 DOI: 10.1007/s12070-011-0322-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2011] [Accepted: 10/27/2011] [Indexed: 10/15/2022] Open
Abstract
The diagnosis of fungal laryngitis is often overlooked in immunocompetent patients because it is commonly considered a disease of the immunocompromised. Further confusion is caused by clinical and histological similarity to more common conditions like Leukoplakia. Demonstration of hyperkeratosis particularly if associated with intraepithelial neutrophils on biopsy should trigger a search for fungus using specialized stains. These patients usually present with hoarseness of voice. Pain is present inconsistently along with dysphagia and odynophagia. We present three cases of fungal laryngitis in immunocompetent patients out of which one underwent microlaryngeal surgery with excision biopsy. All these patients responded well with oral antifungal therapy.
