RESUMO
INTRODUCTION: During the coronavirus disease 2019, pandemic clinical practice had to change, and this study trialled a diagnostic questionnaire to assess patients with dizziness over the telephone. METHODS: All 115 patients awaiting otorhinolaryngological assessment for balance were randomised to receive a dizziness questionnaire in the post prior to their telephone consultation or not. Consultation outcomes were recorded by the clinicians conducting the consultation. Follow-up data were collected in June 2022 for final outcomes. RESULTS: 82/115 patients had consultations with complete data collection: 35 in the questionnaire group (QG) and 47 in the no questionnaire group (NQG), with a 70% response rate in the QG. Clinicians made a diagnosis in 27/35 QG consultations versus 27/47 NQG consultations. Nine out of 35 QG patients required additional investigations compared to 34/47 in the NQG (p < 0.05). Only 6/35 QG patients needed additional telephone follow-up, compared to 20/47 NQG patients (p < 0.05). CONCLUSION: Using a diagnostic questionnaire increased clinicians' ability to come to a diagnosis in telephone consultations.

ENT involvement is common in ANCA-associated vasculitis (AAV), particularly in GPA and EGPA. Early recognition and treatment is important for good outcomes, yet evidence suggests that UK ENT surgeons may not consistently recognise the early features of AAV, despite a similar incidence to vestibular schwannoma. AAV is a rapidly advancing field, with significant developments in the understanding of its pathogenesis, classification and treatment over the past decade. Relevant vasculitis mimics are also discussed with a particular focus on the increasing prevalence of vasculitis mimics driven by an increase in recreational cocaine use, as well as the emergence and reclassification of several other vasculitis mimics in the head and neck. This article reviews key recent updates in the vasculitis literature, with a particular focus on those relevant to recognition and diagnosis of AAV for the ENT surgeon. Strengths and limitations of relevant diagnostic testing are discussed, and a method of evaluation of patients with features of AAV presenting to ENT services is outlined.

INTRODUCTION: Relapses in ANCA-associated vasculitis (AAV) increase the incidence of end-organ damage and their prevention requires prolonged immunosuppressive therapy. Rituximab, a type I anti-CD20 B cell depleting monoclonal antibody, is the current standard of care for induction of disease remission. Rituximab is not always effective and is associated with a high subsequent relapse risk. Obinutuzumab is a type II anti-CD20 humanised monoclonal antibody with the potential to obtain greater tissue B cell depletion than rituximab and reduce relapse risk in AAV. METHODS AND ANALYSIS: ObiVas is a randomised, phase II, double-blind controlled trial that will compare the mechanistic effects of rituximab and obinutuzumab in the induction treatment of patients with AAV positive for proteinase 3 ANCA (PR3-ANCA). 26 patients, either newly diagnosed or relapsing, will be recruited from a single centre and randomised in a 1:1 ratio to receive 1000 mg rituximab or obinutuzumab as induction therapy on days 1 and 15, alongside a tapering glucocorticoid regimen. The primary end point is CD19+ B cell depletion in nasal-associated lymphoid tissue (NALT), assessed as change from baseline to week 26. Secondary outcomes will compare the safety and clinical efficacy of rituximab and obinutuzumab and their impact on immune biomarkers, including tissue and peripheral blood lymphocyte subsets and PR3-ANCA binding levels. Patients are followed through to week 78. The trial opened for recruitment in January 2023 and is forecasted to complete recruitment by the end of 2024. ETHICS AND DISSEMINATION: For all patients, informed written consent will be obtained in keeping with Good Clinical Practice. Trial results will be disseminated to the relevant scientific, clinical and patient communities on trial closure. NALT data analysis will start before trial completion. Other analyses will be reported after trial completion. This trial was given ethical approval by Edgbaston (West Midlands) Research Ethics Committee (approval reference 22/WM/0174). TRIAL REGISTRATION NUMBER: ISRCTN13069630.

The objective of this prospective cross-sectional study is to describe the clinical otorhinolaryngological manifestations of granulomatosis with polyangiitis (Wegener's) (GPA) in a prospective cohort. All patients suffering from GPA seen in a tertiary centre between March 2007 and November 2008 had a detailed clinical assessment by an ENT surgeon of their ear, nose and head and neck complaints. An evaluation of whether there was disease activity and/or infection in each ENT area was made using the European Vasculitis Study Group guidelines. The number of patients assessed was 144. The proportion of female patients was 47 % (n = 69) and the median age was 57.7 years (IQ range 42.5-68.5). The prevalence of ENT involvement was 87 % (125/144). Hearing loss and abnormal tympanic membrane appearance were more common in patients with active disease and no infection (7/8 and 6/8, respectively, in active disease cf. 59/131 and 52/131, respectively, in remission). Nasal crusting was the most common nasal complaint recorded (52/144, 36 %) and bloody rhinorrhoea was the most common symptom in patients with disease activity. Rhinoscopy was highly sensitive in diagnosing disease activity (100 %). Subglottic stenosis was the most common head and neck manifestation (27/121, 22 %) and 74 % were symptomatic. In conclusion, the pattern and frequency of clinical ENT manifestations in GPA have been described in a large patient cohort. The use of tools readily available in the ENT clinic was essential to assess these patients accurately. This dataset will form the basis of an objective scoring system to measure disease activity in the ENT system.

Mandibular swing is the approach of choice for resection of advanced oropharyngeal carcinomas without bone involvement. This approach requires a mandibulotomy, which is associated with complications. A prospective outcome analysis was performed for 21 patients operated without mandibulotomy for T3-T4a oropharyngeal carcinoma. Tumour size was categorized as T3 in 14 patients (66.7 %) and as T4a (33.3 %) in 7 patients. Twelve patients were N0 (57.1 %), 2 (9.5 %) were N1, and 7 (33.3 %) were N2. Surgical margins were negative in 18 cases (85.7 %), positive in 1 (4.8 %), and close in 2 (9.5 %). Average hospital stay was 14.5 days (range 10-22). Adjuvant treatment (radiotherapy or concurrent chemoradiotherapy) was administered to all but three patients previously irradiated. In all cases radiotherapy started within 42 days of surgery. The 3-year overall survival was 85.7 %, and relapse-free survival was 71.4 %. Oropharyngectomy without mandibulotomy has the same indications as mandibular swing. It provides good access to achieve satisfactory clearance of tumours, sparing patients the morbidity associated with mandibulotomy.

The objectives of the study are to describe long-term ENT damage and assess risk factors in patients with newly diagnosed and treated Wegener's granulomatosis (WG) using the vasculitis damage index (VDI). Data from four randomised controlled trials carried out by the European Vasculitis Study Group was used. Patients newly diagnosed with WG with complete data at 5 years were included. Patients enrolled into the trials without 5-year data were excluded. Total and ENT VDI scores were recorded at 12 months and after at least 5 years. Logistic regression models were constructed to assess risk factors using total ENT and overall VDI score over the follow-up period, the proportion of patients with increased VDI score and the presence or absence of damage as the main outcomes. One hundred and thirty-eight patients were included. Ninety patients (65%) had long-term damage and 81% of these (73/90) developed some damage in the first 12 months. Positive ENT activity score (BVAS) at baseline and relapses were associated with higher ENT VDI scores long-term (OR = 6.90, 95% CI 2.01-23.75; OR = 2.65, 95% CI 1.20-5.82). Increasing BVAS score showed a trend towards lower VDI scores (OR = 0.93, 95% CI 0.88-0.99). Only ENT relapses and number of relapses were associated with an increase in VDI over time (OR = 8.38, 95% CI 3.10-22.68; OR = 1.79, 95% CI 1.24-2.58). In conclusion, most of the ENT damage in these patients was accrued within 12 months of diagnosis. We have shown an association between later ENT damage and the presence of ENT disease at baseline; lower initial BVAS and higher rate of disease relapse.

OBJECTIVE: Evidence for the management of acute otitis externa (AOE) is limited, with unclear diagnostic criteria and variably reported outcome measures that may not reflect key stakeholder priorities. We aimed to develop 1) a definition, 2) diagnostic criteria and 3) a core outcome set (COS) for AOE. STUDY DESIGN: COS development according to Core Outcome Measures in Effectiveness Trials (COMET) methodology and parallel consensus selection of diagnostic criteria/definition. SETTING: Stakeholders from the United Kingdom. SUBJECTS AND METHODS: Comprehensive literature review identified candidate items for the COS, definition and diagnostic criteria. Nine individuals with past AOE generated further patient-centred candidate items. Candidate items were rated for importance by patient and professional (ENT doctors, general practitioners, microbiologists, nurses, audiologists) stakeholders in a three-round online Delphi exercise. Consensus items were grouped to form the COS, diagnostic criteria, and definition. RESULTS: Candidate COS items from patients (n = 28) and literature (n = 25) were deduplicated and amalgamated to a final candidate list (n = 46). Patients emphasised quality-of-life and the impact on daily activities/work. Via the Delphi process, stakeholders agreed on 31 candidate items. The final COS covered six outcomes: pain; disease severity; impact on quality-of-life and daily activities; patient satisfaction; treatment-related outcome; and microbiology. 14 candidate diagnostic criteria were identified, 8 reaching inclusion consensus. The final definition for AOE was 'diffuse inflammation of the ear canal skin of less than 6 weeks duration'. CONCLUSION: The development and adoption of a consensus definition, diagnostic criteria and a COS will help to standardise future research in AOE, facilitating meta-analysis. Consulting former patients throughout development highlighted deficiencies in the outcomes adopted previously, in particular concerning the impact of AOE on daily life.

Vestibular schwannomas are benign, slow-growing tumors that originate from Schwann cells lining the vestibular nerves, most commonly the superior vestibular nerve. They arise at the neurilemmal/neuroglial junction which is situated within the internal auditory canal. They have an incidence of 1 per 100,000 per year and a prevalence of around 700 per million. A case of a patient undergoing a period of observation for a vestibular schwannoma whose hearing improved despite growth of the tumor is described. This raises interesting questions regarding the pathophysiology of hearing loss in patients with vestibular schwannomas. Possible hypotheses are discussed.
RESUMO
BACKGROUND: Ear, nose and throat involvement in granulomatosis with polyangiitis (GPA) is frequently the initial disease manifestation. Previous investigations have observed a higher prevalence of Staphylococcus aureus in patients with GPA, and chronic nasal carriage has been linked with an increased risk of disease relapse. In this cross-sectional study, we investigated changes in the nasal microbiota including a detailed analysis of Staphylococcus spp. by shotgun metagenomics in patients with active and inactive granulomatosis with polyangiitis (GPA). Shotgun metagenomic sequence data were also used to identify protein-encoding genes within the SEED database, and the abundance of proteins then correlated with the presence of bacterial species on an annotated heatmap. RESULTS: The presence of S. aureus in the nose as assessed by culture was more frequently detected in patients with active GPA (66.7%) compared with inactive GPA (34.1%). Beta diversity analysis of nasal microbiota by bacterial 16S rRNA profiling revealed a different composition between GPA patients and healthy controls (P = 0.039). Beta diversity analysis of shotgun metagenomic sequence data for Staphylococcus spp. revealed a different composition between active GPA patients and healthy controls and disease controls (P = 0.0007 and P = 0.0023, respectively), and between healthy controls and inactive GPA patients and household controls (P = 0.0168 and P = 0.0168, respectively). Patients with active GPA had a higher abundance of S. aureus, mirroring the culture data, while healthy controls had a higher abundance of S. epidermidis. Staphylococcus pseudintermedius, generally assumed to be a pathogen of cats and dogs, showed an abundance of 13% among the Staphylococcus spp. in our cohort. During long-term follow-up of patients with inactive GPA at baseline, a higher S. aureus abundance was not associated with an increased relapse risk. Functional analyses identified ten SEED protein subsystems that differed between the groups. Most significant associations were related to chorismate synthesis and involved in the vitamin B12 pathway. CONCLUSION: Our data revealed a distinct dysbiosis of the nasal microbiota in GPA patients compared with disease and healthy controls. Metagenomic sequencing demonstrated that this dysbiosis in active GPA patients is manifested by increased abundance of S. aureus and a depletion of S. epidermidis, further demonstrating the antagonist relationships between these species. SEED functional protein subsystem analysis identified an association between the unique bacterial nasal microbiota clusters seen mainly in GPA patients and an elevated abundance of genes associated with chorismate synthesis and vitamin B12 pathways. Further studies are required to further elucidate the relationship between the biosynthesis genes and the associated bacterial species.

IMPORTANCE: Airway stenosis occurs in patients with granulomatosis with polyangiitis (GPA or Wegener granulomatosis). It produces significant morbidity and contributes to mortality. OBJECTIVE: To investigate the frequency and distribution of airway stenoses in GPA and evaluate the efficacy of local interventions in maintaining airway patency. DESIGN, SETTING, AND PARTICIPANTS: A retrospective single-center study of 44 patients with GPA and airway stenosis assessed and treated as needed by a multidisciplinary team at a university medical center between 1997 and 2012. The median duration of observation for each patient from the time of diagnosis was 146 months. INTERVENTIONS: Patients who had critical stenoses underwent either dilatation or laser radial cuts to the lesion. In some cases, intralesional administration of steroids or topical mitomycin C was used. MAIN OUTCOMES AND MEASURES: The main outcome measure was airway patency for at least 12 months and the number of interventions required to achieve this end point. Details of patients and interventions were recorded at baseline and at each treatment. RESULTS: The median age at diagnosis was 37.6 years; 73% of patients were women (n = 34). The median follow-up after the initial intervention was 62.5 months. Subglottic stenosis was found in 36 patients, lower airway stenosis in 30. There were 213 interventions in 39 patients, including balloon and bougie dilatation and laser treatment. Adjuvant local treatment was used in 71 interventions. A 12-month period of airway stability was achieved in 34 of 36 cases (97%) (5 had no procedures and 3 had follow-up shorter than 12 months). The median interval between procedures was 4.9 months, and after the last intervention recorded, patients had at least 27 months of airway stability. Fourteen adverse events were recorded (6.6%). CONCLUSIONS AND RELEVANCE: The frequency and distribution of airway stenoses in 44 patients with GPA has been described. In the 39 patients who required intervention, multiple procedures were required, but 97% then achieved a prolonged period of airway patency. The procedures and adjuvant treatments were found to be safe. Our experience with a variety of techniques in this rare presentation has permitted design of a structured approach and an algorithm to manage and evaluate airway stenosis in GPA.
