Abstract
BACKGROUND Chronic rhinosinusitis (CRS) disease control is a global metric of disease status for CRS. While there is broad acceptance that it is an important treatment goal, there has been inconsistency in the criteria used to define CRS control. The objective of this study was to identify and develop consensus around essential criteria for assessment of CRS disease control. METHODS Modified Delphi methodology consisting of three rounds to review a list of 24 possible CRS control criteria developed by a 12-person steering committee. The core authorship of the multidisciplinary EPOS 2020 guidelines was invited to participate. RESULTS Thirty-two individuals accepted the invitation to participate and there was no dropout of participants throughout the entire study (3 rounds). Consensus essential criteria for assessment of CRS control were: overall symptom severity, need for CRS-related systemic corticosteroids in the prior 6 months, severity of nasal obstruction, and patient-reported CRS control. Near-consensus items were: nasal endoscopy findings, severity of smell loss, overall quality of life, impairment of normal activities and severity of nasal discharge. Participants’ comments provided insights into caveats of, and disagreements related to, near-consensus items. CONCLUSIONS Overall symptom severity, use of CRS-related systemic corticosteroids, severity of nasal obstruction, and patient-reported CRS control are widely agreed upon essential criteria for assessment of CRS disease control. Consideration of near-consensus items to assess CRS control should be implemented with their intrinsic caveats in mind. These identified consensus CRS control criteria, together with evidence-based support, will provide a foundation upon which CRS control criteria with wide-spread acceptance can be developed.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a heterogeneous condition characterized by differing inflammatory endotypes. The identification of suitable biomarkers could enable personalized approaches to treatment selection. OBJECTIVE This study aimed to identify and summarize clinical studies of biomarkers in adults with CRS in order to inform future research into CRS endotypes. METHODS We conducted systematic searches of MEDLINE and Web of Science from inception to January 30, 2022 and included all clinical studies of adult CRS patients and healthy controls measuring biomarkers using enzyme-linked immunosorbent assays or Luminex immunoassays. Outcomes included the name and tissue type of identified biomarkers and expression patterns within CRS phenotypes. Study quality was assessed using the National Institutes of Health quality assessment tool for observational cohort and cross-sectional studies. A narrative synthesis was performed. RESULTS We identified 78 relevant studies involving up to 9394 patients, predominantly with CRS with nasal polyposis. Studies identified 80 biomarkers from nasal tissue, 25 from nasal secretions, 14 from nasal lavage fluid, 24 from serum, and one from urine. The majority of biomarkers found to distinguish CRS phenotypes were identified in nasal tissue, especially in nasal polyps. Serum biomarkers were more commonly found to differentiate CRS from controls. The most frequently measured biomarker was IL-5, followed by IL-13 and IL-4. Serum IgE, IL-17, pentraxin-3 and nasal phospho-janus kinase 2, IL-5, IL-6, IL-17A, granulocyte-colony stimulating factor, and interferon gamma were identified as correlated with disease severity. CONCLUSION We have identified numerous potential biomarkers to differentiate a range of CRS phenotypes. Future studies should focus on the prognostic role of nasal tissue biomarkers or expand on the more limited studies of nasal secretions and nasal lavage fluid.We registered this study in PROSPERO (CRD42022302787).

Olfactory Nomenclature: An Orchestrated Effort to Clarify Terms and Definitions of Dysosmia, Anosmia, Hyposmia, Normosmia, Hyperosmia, Olfactory Intolerance, Parosmia, and Phantosmia/Olfactory Hallucination. ORL J Otorhinolaryngol Relat Spec 2023; 85:312-320. [PMID: 37062268 PMCID: PMC10711772 DOI: 10.1159/000530211] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2022] [Accepted: 03/10/2023] [Indexed: 04/18/2023]
Abstract
BACKGROUND Definitions are essential for effective communication and discourse, particularly in science. They allow the shared understanding of a thought or idea, generalization of knowledge, and comparison across scientific investigation. The current terms describing olfactory dysfunction are vague and overlapping. SUMMARY As a group of clinical olfactory researchers, we propose the standardization of the terms "dysosmia," "anosmia," "hyposmia," "normosmia," "hyperosmia," "olfactory intolerance," "parosmia," and "phantosmia" (or "olfactory hallucination") in olfaction-related communication, with specific definitions in this text. KEY MESSAGES The words included in this paper were determined as those which are most frequently used in the context of olfactory function and dysfunction, in both clinical and research settings. Despite widespread use in publications, however, there still exists some disagreement in the literature regarding the definitions of terms related to olfaction. Multiple overlapping and imprecise terms that are currently in use are confusing and hinder clarity and universal understanding of these concepts. There is a pressing need to have a unified agreement on the definitions of these olfactory terms by researchers working in the field of chemosensory sciences. With the increased interest in olfaction, precise use of these terms will improve the ability to integrate and advance knowledge in this field.

Establishing UK research priorities in smell and taste disorders: A James Lind alliance priority setting partnership. Clin Otolaryngol 2023; 48:17-24. [PMID: 36148690 PMCID: PMC10092439 DOI: 10.1111/coa.13985] [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: 04/10/2022] [Revised: 07/13/2022] [Accepted: 09/10/2022] [Indexed: 01/07/2023]
Abstract
OBJECTIVES To determine the top 10 research priorities in Smell and Taste Disorders (SATD). DESIGN After steering group was established, an electronic survey was disseminated to determine the list of questions. After removing out-of-scope responses, the remainder were consolidated to create summary questions. A literature search was conducted to remove already answered questions. A second survey was used to determine the top questions that formed the subject of final debate at a workshop attended by clinicians and patients to determine the top 10 priorities. SETTING A James Lind Alliance Priority Setting Partnership (JLAPSP) was established by FifthSense to identify the top 10 research questions in SATDs in the United Kingdom. PARTICIPANT All stakeholders in SATDs (patients, healthcare professionals, family, carers, researchers). MAIN OUTCOME MEASURES Final 10 research priorities. RESULTS The 665 respondents to the initial survey provided 1698 research questions. Thirteen were out-of-scope and removed; remaining 1685 were then consolidated to form 147 summary questions. Following literature search and discussion with the steering group, 37 questions remained for the second survey, which 235 people responded. The top ten priorities agreed upon in the workshop covered themes of improved understanding of pathophysiologlogy, improving health services, and managing long-term effects of smell/taste disorders. The most important research question agreed was "How can we further our understanding of the mechanism of disease in the nerve pathways that affect smell and taste disorders, including where parosmia and phantosmia exist." CONCLUSION We report the top 10 research priorities in smell and taste disorders. These priorities will now empower researchers to secure research funding and provide the basis of the FifthSense research hub.

Observational retrospective study calculating health service costs of patients receiving surgery for chronic rhinosinusitis in England, using linked patient-level primary and secondary care electronic data. BMJ Open 2022; 12:e055603. [PMID: 35135774 PMCID: PMC8830221 DOI: 10.1136/bmjopen-2021-055603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Accepted: 01/11/2022] [Indexed: 11/18/2022] Open
Abstract
OBJECTIVES Chronic rhinosinusitis (CRS) symptoms are experienced by an estimated 11% of UK adults, and symptoms have major impacts on quality of life. Data from UK and elsewhere suggest high economic burden of CRS, but detailed cost information and economic analyses regarding surgical pathway are lacking. This paper estimates healthcare costs for patients receiving surgery for CRS in England. DESIGN Observational retrospective study examining cost of healthcare of patients receiving CRS surgery. SETTING Linked electronic health records from the Clinical Practice Research Datalink, Hospital Episode Statistics and Office for National Statistics databases in England. PARTICIPANTS A phenotyping algorithm using medical ontology terms identified 'definite' CRS cases who received CRS surgery. Patients were registered with a general practice in England. Data covered the period 1997-2016. A cohort of 13 462 patients had received surgery for CRS, with 9056 (67%) having confirmed nasal polyps. OUTCOME MEASURES Information was extracted on numbers and types of primary care prescriptions and consultations, and inpatient and outpatient hospital investigations and procedures. Resource use was costed using published sources. RESULTS Total National Health Service costs in CRS surgery patients were £2173 over 1 year including surgery. Total costs per person-quarter were £1983 in the quarter containing surgery, mostly comprising surgical inpatient care costs (£1902), and around £60 per person-quarter in the 2 years before and after surgery, of which half were outpatient costs. Outpatient and primary care costs were low compared with the peak in inpatient costs at surgery. The highest outpatient expenditure was on CT scans, peaking in the quarter preceding surgery. CONCLUSIONS We present the first study of costs to the English healthcare system for patients receiving surgery for CRS. The total aggregate costs provide a further impetus for trials to evaluate the relative benefit of surgical intervention.

Abstract
Abstract
Introduction
Olfactory testing must be culturally adapted to be relevant to the target population. This study aimed to validate the Sniffin’ Sticks test for the UK setting.
Methods
A cohort study was conducted at a tertiary olfactory dysfunction clinic. Phase 1—healthy volunteers underwent the original German identification test followed by a UK adapted version. Phase 2—patients with olfactory dysfunction underwent the extended smell test (TDI) including the new descriptors. Outcome measures included differences in identification test (phase 1), retest reliability and differences in scores before and after treatment.
Results
A total of 31 healthy volunteers and 87 patients were recruited (6 and 31 males, respectively). Phase 1—mean identification scores showed a small improvement after descriptor adaptations (13.77 and 14.57, p = 0.0029). Phase 2—41 untreated participants had a mean identification score of 7.31 at both intervals (95% CI: − 1.15 to 1.15, p > 0.999). The mean change in treated participants was 1.88 (0.70 to 3.06, p = 0.0224). TDI score difference between treated and untreated groups was 6.63 (2.48 to 10.79, p = 0.0023). The intraclass correlation coefficient for untreated patients was high for both TDI score (ICC = 0.82, 95% CI 0.57 to 0.93) and identification score (ICC = 0.80, 0.52 to 0.93); CIs suggest the reliability is moderate to excellent.
Conclusions
This study confirms the validity of the descriptor adaptations of the identification component of the Sniffin’ Sticks test to distinguish between health and disease.
Implications
The Sniffin’ Sticks test can now reliably be used for clinical assessment of British patients, modifying only the descriptors.

Barriers to effective health care for patients who have smell or taste disorders. Clin Otolaryngol 2021; 46:1213-1222. [PMID: 34085404 PMCID: PMC8239785 DOI: 10.1111/coa.13818] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 05/04/2021] [Accepted: 05/23/2021] [Indexed: 12/21/2022]
Abstract
Objectives Smell/taste disturbances are a common but underrated, under‐researched and under treated sensory loss and an independent risk factor for reduced longevity. This study aimed to characterise the experience of patients with these disorders in seeking help. Design The study was designed by patients together with clinicians through a dedicated workshop and conducted as a cross‐sectional survey to capture experiences in public and private healthcare settings internationally. Setting Primary, secondary and tertiary care. Participants Any members of the public self‐reporting a smell/taste disorder were invited to participate. Main outcome measures The survey captured information including experience of getting consultations and referrals to medical professionals, treatments offered, costs incurred and related problems with mental health. Results Of 673 participants; 510 female, 160 male, three not stated, self‐reported aetiology included sinonasal disease (24%), idiopathic (24%) and post‐viral olfactory dysfunction (22%); true gustatory disorders were typically rare. Failure of medical professionals to recognise the problem was a key concern ‐ 64%, 76% and 47% of GPs, ENT specialists and Neurologists acknowledged, respectively. Other issues included repeated ineffective treatments, difficulties getting referrals to secondary/tertiary care, mental health problems (60%) and a mean personal cost of £421 to seeking advice and treatment. Whilst the participants were self‐selecting, however, they do represent those who are seeking help and intervention for their disorders. Conclusion There is an unmet need for these patients in accessing health care including a clear need to improve education of and engagement with the medical profession in Otorhinolaryngology, General Practice and other specialties, in order to remove the current barriers they face.

Abstract
INTRODUCTION To highlight the importance of the need for new treatment modalities, this study aimed to characterise the experience of patients with postinfectious olfactory dysfunction (PIOD) in terms of the treatment they received. METHODS An online survey was hosted by the Norwich Clinical Trials Unit on the secure REDCap server. Members of the charity Fifth Sense (the UK charity that represents and supports people affected by smell and taste disorders) were invited to participate. RESULTS There were 149 respondents, of whom 127 had identified themselves as having (or had) PIOD. The age range of respondents to the survey was 28-85 years, with a mean of 58 ± 12 years, with the duration of their disorder <5 years in 63% of cases. Respondents reported experiencing variable treatment with oral and/or intranasal steroids given typically (28%), often with no benefit, but with 50% receiving no treatment whatsoever; only 3% reported undertaking olfactory training. Over two-thirds of patients experience parosmia and, up to 5 years from the onset of the problem, were still actively seeking a solution. CONCLUSION There appears to be a need to encourage greater use of guidelines for olfactory disorders amongst medical practitioners and also to develop more effective treatments for patients with PIOD, where there is clearly an unmet need.

Abstract
The frequent association between coronavirus disease 2019 (COVID‐19) and olfactory dysfunction is creating an unprecedented demand for a treatment of the olfactory loss. Systemic corticosteroids have been considered as a therapeutic option. However, based on current literature, we call for caution using these treatments in early COVID‐19–related olfactory dysfunction because: (1) evidence supporting their usefulness is weak; (2) the rate of spontaneous recovery of COVID‐19–related olfactory dysfunction is high; and (3) corticosteroids have well‐known potential adverse effects. We encourage randomized placebo‐controlled trials investigating the efficacy of systemic steroids in this indication and strongly emphasize to initially consider smell training, which is supported by a robust evidence base and has no known side effects.

Abstract
Objectives To assess the safety of paediatric tonsillectomy procedures conducted in NHS hospitals in England between 2008 and 2019. Design Retrospective observational cohort study using Hospital Episode Statistics (HES) data. Setting Acute NHS trusts in England conducting paediatric tonsillectomy procedures. Participants Children (≤16 years old) undergoing bilateral tonsillectomy. Main outcome measures Number of tonsillectomies performed per year by procedural method. In‐hospital complications including return to theatre for arrest of haemorrhage. Readmission within 28 days, including those for pain, haemorrhage and surgical arrest of haemorrhage. Long‐term outcomes: all‐cause mortality, revision tonsillectomy. Results A total of 318 453 paediatric tonsillectomies were performed from 2008 to 2019:278,772 dissection (87.5%) and 39 681 coblation (12.5%). The proportion of tonsillectomy performed using coblation increased from 7% in 2008/9 to 27% in 2018/9. Five patients died in hospital (including 4 due to respiratory complications). In‐hospital complications occurred in 4202 children (1.3%), with the most frequent being haemorrhage. Within 28 days of tonsillectomy, 28 170 patients (8.8%) were readmitted and 7 deaths occurred. Readmission rates for haemorrhage and pain have increased since 2008. The proportion of children undergoing revision tonsillectomy procedures within 5 years following coblation tonsillectomy (1.4%) was approximately double that of dissection (0.6%). Conclusions Clinical practice of paediatric tonsillectomy has changed in England over the past 11 years. The overall mortality rate associated with the procedure is 0.0037%. Differences in outcomes have been identified for different procedural methods. However, routine administrative data are limited in differentiating procedural detail (eg we are unable to differentiate intra or extra‐capsular techniques from current clinical coding of tonsillectomy procedures). Therefore, prospective national data collection or more granular clinical coding is essential to capture relative outcomes of the different tonsillectomy methods and techniques being used in the NHS.

Abstract
BACKGROUND Respiratory tract viruses are the second most common cause of olfactory dysfunction. As we learn more about the effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), with the recognition that olfactory dysfunction is a key symptom of this disease process, there is a greater need than ever for evidence-based management of postinfectious olfactory dysfunction (PIOD). OBJECTIVE Our aim was to provide an evidence-based practical guide to the management of PIOD (including post-coronavirus 2019 cases) for both primary care practitioners and hospital specialists. METHODS A systematic review of the treatment options available for the management of PIOD was performed. The written systematic review was then circulated among the members of the Clinical Olfactory Working Group for their perusal before roundtable expert discussion of the treatment options. The group also undertook a survey to determine their current clinical practice with regard to treatment of PIOD. RESULTS The search resulted in 467 citations, of which 107 articles were fully reviewed and analyzed for eligibility; 40 citations fulfilled the inclusion criteria, 11 of which were randomized controlled trials. In total, 15 of the articles specifically looked at PIOD whereas the other 25 included other etiologies for olfactory dysfunction. CONCLUSIONS The Clinical Olfactory Working Group members made an overwhelming recommendation for olfactory training; none recommended monocycline antibiotics. The diagnostic role of oral steroids was discussed; some group members were in favor of vitamin A drops. Further research is needed to confirm the place of other therapeutic options.

Abstract
In a preregistered, cross-sectional study, we investigated whether olfactory loss is a reliable predictor of COVID-19 using a crowdsourced questionnaire in 23 languages to assess symptoms in individuals self-reporting recent respiratory illness. We quantified changes in chemosensory abilities during the course of the respiratory illness using 0-100 visual analog scales (VAS) for participants reporting a positive (C19+; n = 4148) or negative (C19-; n = 546) COVID-19 laboratory test outcome. Logistic regression models identified univariate and multivariate predictors of COVID-19 status and post-COVID-19 olfactory recovery. Both C19+ and C19- groups exhibited smell loss, but it was significantly larger in C19+ participants (mean ± SD, C19+: -82.5 ± 27.2 points; C19-: -59.8 ± 37.7). Smell loss during illness was the best predictor of COVID-19 in both univariate and multivariate models (ROC AUC = 0.72). Additional variables provide negligible model improvement. VAS ratings of smell loss were more predictive than binary chemosensory yes/no-questions or other cardinal symptoms (e.g., fever). Olfactory recovery within 40 days of respiratory symptom onset was reported for ~50% of participants and was best predicted by time since respiratory symptom onset. We find that quantified smell loss is the best predictor of COVID-19 amongst those with symptoms of respiratory illness. To aid clinicians and contact tracers in identifying individuals with a high likelihood of having COVID-19, we propose a novel 0-10 scale to screen for recent olfactory loss, the ODoR-19. We find that numeric ratings ≤2 indicate high odds of symptomatic COVID-19 (4 < OR < 10). Once independently validated, this tool could be deployed when viral lab tests are impractical or unavailable.

Abstract
Recent anecdotal and scientific reports have provided evidence of a link between COVID-19 and chemosensory impairments such as anosmia. However, these reports have downplayed or failed to distinguish potential effects on taste, ignored chemesthesis, and generally lacked quantitative measurements. Here, we report the development, implementation and initial results of a multi-lingual, international questionnaire to assess self-reported quantity and quality of perception in three distinct chemosensory modalities (smell, taste, and chemesthesis) before and during COVID-19. In the first 11 days after questionnaire launch, 4039 participants (2913 women, 1118 men, 8 other, ages 19-79) reported a COVID-19 diagnosis either via laboratory tests or clinical assessment. Importantly, smell, taste and chemesthetic function were each significantly reduced compared to their status before the disease. Difference scores (maximum possible change ±100) revealed a mean reduction of smell (-79.7 ± 28.7, mean ± SD), taste (-69.0 ± 32.6), and chemesthetic (-37.3 ± 36.2) function during COVID-19. Qualitative changes in olfactory ability (parosmia and phantosmia) were relatively rare and correlated with smell loss. Importantly, perceived nasal obstruction did not account for smell loss. Furthermore, chemosensory impairments were similar between participants in the laboratory test and clinical assessment groups. These results show that COVID-19-associated chemosensory impairment is not limited to smell, but also affects taste and chemesthesis. The multimodal impact of COVID-19 and lack of perceived nasal obstruction suggest that SARS-CoV-2 infection may disrupt sensory-neural mechanisms.

Abstract
BACKGROUND COVID-19 has heterogeneous manifestations, though one of the most common symptoms is a sudden loss of smell (anosmia or hyposmia). We investigated whether olfactory loss is a reliable predictor of COVID-19. METHODS This preregistered, cross-sectional study used a crowdsourced questionnaire in 23 languages to assess symptoms in individuals self-reporting recent respiratory illness. We quantified changes in chemosensory abilities during the course of the respiratory illness using 0-100 visual analog scales (VAS) for participants reporting a positive (C19+; n=4148) or negative (C19-; n=546) COVID-19 laboratory test outcome. Logistic regression models identified singular and cumulative predictors of COVID-19 status and post-COVID-19 olfactory recovery. RESULTS Both C19+ and C19- groups exhibited smell loss, but it was significantly larger in C19+ participants (mean±SD, C19+: -82.5±27.2 points; C19-: -59.8±37.7). Smell loss during illness was the best predictor of COVID-19 in both single and cumulative feature models (ROC AUC=0.72), with additional features providing no significant model improvement. VAS ratings of smell loss were more predictive than binary chemosensory yes/no-questions or other cardinal symptoms, such as fever or cough. Olfactory recovery within 40 days was reported for ~50% of participants and was best predicted by time since illness onset. CONCLUSIONS As smell loss is the best predictor of COVID-19, we developed the ODoR-19 tool, a 0-10 scale to screen for recent olfactory loss. Numeric ratings ≤2 indicate high odds of symptomatic COVID-19 (10<OR<4), especially when viral lab tests are impractical or unavailable.

Cholesteatoma and family history: An international survey. Clin Otolaryngol 2020; 45:500-505. [PMID: 32271986 DOI: 10.1111/coa.13544] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2019] [Revised: 02/15/2020] [Accepted: 03/08/2020] [Indexed: 11/28/2022]
Abstract
OBJECTIVE To explore the relative frequency of a family history of cholesteatoma in patients with known cholesteatoma, and whether bilateral disease or earlier diagnosis is more likely in those with a family history. Associations between cleft lip or palate and bilateral disease and age of diagnosis were also explored. DESIGN An online survey of patients with diagnosed cholesteatoma was conducted between October 2017 and April 2019. PARTICIPANTS The sample consisted of patients recruited from two UK clinics and self-selected respondents recruited internationally via social media. MAIN OUTCOME MEASURES Side of cholesteatoma, whether respondents had any family history of cholesteatoma, age of diagnosis and personal or family history of cleft lip or palate were recorded. RESULTS Of 857 respondents, 89 (10.4%) reported a positive family history of cholesteatoma. Respondents with a family history of cholesteatoma were more likely to have bilateral cholesteatoma (P = .001, odds ratio (OR) 2.15, 95% confidence interval (CI) 1.35-3.43), but there was no difference in the age of diagnosis (P = .23). Those with a history of cleft lip or palate were not more likely to have bilateral disease (P = .051, OR 2.71, CI 1.00-7.38), and there was no difference in age of diagnosis (P = .11). CONCLUSION The relatively high proportion of respondents that reported a family history of cholesteatoma offers supporting evidence of heritability in cholesteatoma. The use of social media to recruit respondents to this survey means that the results cannot be generalised to other populations with cholesteatoma. Further population-based research is suggested to determine the heritability of cholesteatoma.

Abstract
INTRODUCTION Chronic rhinosinusitis (CRS) is highly prevalent, affecting 11% of the population. Studies evaluating the socio-economic impact of CRS are mostly limited to the US population. Currently there is no study that has evaluated the socio-economic costs of CRS in the UK. METHODS A case-control study of patients with CRS and healthy controls was conducted to investigate the wider socio-economic impact of the disease. Data on demographic and socioeconomic characteristics, out-of-pocket expenditure (OOPE), health resource utilisation, productivity losses and health-related quality of life (HRQoL) via the EQ-5D and SNOT-22 instruments, were collected from questionnaires. RESULTS A total of 139 CRS participants and 67 control participants completed the questionnaires. The average total OOPE per patient extrapolated to a 12-month period was £304.84. Other important findings include significantly higher reported primary care interactions (4.14 vs. 1.16) as well as secondary care interactions (2.61 vs 0.4) in CRS group as compared to controls over three-months. The average total missed workdays was estimated to be 18.7 per patient per year. The estimated incremental healthcare cost of CRS per year is £16.8 billion or £2.8 billion per million inhabitants. Factors predictive of a higher OOPE include higher household occupancy and income and these accounted for only 9.7% of the total variance in total OOPEs. Other socioeconomic, demographic and HRQoL variables were not found to be predictive factors of OOPE. CONCLUSIONS This study showed that CRS has a significant wider economic burden beyond the immediate direct healthcare costs. CRS participants had a high level of healthcare service use, OOPE and productivity loss. Results from this study will add to the existing limited data both for the UK and abroad and emphasises the need for effective treatments for these patients to reduce the disease impact.

Abstract
The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012. The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings. EPOS2020 contains chapters on definitions and classification where we have defined a large number of terms and indicated preferred terms. A new classification of CRS into primary and secondary CRS and further division into localized and diffuse disease, based on anatomic distribution is proposed. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, allergic rhinitis, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. All available evidence for the management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is systematically reviewed and integrated care pathways based on the evidence are proposed. Despite considerable increases in the amount of quality publications in recent years, a large number of practical clinical questions remain. It was agreed that the best way to address these was to conduct a Delphi exercise . The results have been integrated into the respective sections. Last but not least, advice for patients and pharmacists and a new list of research needs are included.

Abstract
OBJECTIVES There are large numbers of patients with olfactory disturbance in the UK and shortfalls in assessment and support amongst mainstream practice in both primary and secondary care leading to significant quality-of-life impairment and potential missed diagnoses. The aim of this study was to determine the key themes which can be identified from the accounts of anosmia sufferers and to identify important areas to target for future research or service development. DESIGN Qualitative analysis of written patient accounts from patients corresponding with a tertiary smell and taste clinic in the UK. This qualitative study utilised unstructured written patient accounts from consenting patients experiencing olfactory disturbances received by the smell and taste clinic. Framework analysis was performed using Nvivo 10 software. SETTING Tertiary smell and taste clinic. PARTICIPANTS Consenting patients who contacted the smell and taste clinic with accounts of their experiences. MAIN OUTCOME MEASURES Themes generated by qualitative analysis with Nvivo software. RESULTS Accounts submitted by 71 participants were included in the analysis; age range 31-80 years, 45 females, 26 males. Themes identified include negative emotional impact, feelings of isolation, impaired relationships and daily functioning, impact on physical health and the difficulty and financial burden of seeking help. CONCLUSIONS Olfactory disturbances have a wide-ranging impact on the lives of sufferers, compounded by a lack of knowledge of the disorder amongst clinicians. There is a role for further support and education both for sufferers and for clinicians, as well as a need to improve our understanding of olfactory disturbance.

Exploring the association between ingestion of foods with higher potential salicylate content and symptom exacerbation in chronic rhinosinusitis. Data from the National Chronic Rhinosinusitis Epidemiology Study. Rhinology 2019; 57:303-312. [PMID: 31120456 DOI: 10.4193/rhin19.027] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/08/2022]
Abstract
INTRODUCTION Pharmacological salicylates are known to trigger respiratory exacerbations in patients with Non-Steroidal Exacerbated Respiratory Disease (N-ERD), a specific phenotype of Chronic Rhinosinusitis (CRS) and asthma. The impact of dietary sources of salicylates across subgroups of CRS is not well understood. The hypothesis is that in patients with nasal polyps present, there is likely to be a higher incidence of symptom exacerbation due to dietary salicylates regardless of any known response to pharmacological salicylate. METHODS The Chronic Rhinosinusitis Epidemiology Study (CRES) was a questionnaire-based case-control study which sought to characterise the UK CRS population in terms of sociological, economic and medical factors. Using specific questions to examine participant responses relating to symptom exacerbation from food groups thought to be high in salicylate content, this analysis of the CRES database sought to compare an estimate of the prevalence of dietary sensitivity due to food with higher potential salicylate content across patients with CRS with (CRSwNPs) and without nasal polyposis (CRSsNPs) and with allergic fungal rhinosinusitis (AFRS). RESULTS The CRSwNPs group were significantly more likely than controls to report symptom exacerbation due to ingestion of food groups with higher potential dietary salicylate content. The same trend was observed amongst CRSsNPs participants to a lesser degree. Reported response to the individual specific food groups wine, nuts, spicy foods, fruit and vegetables demonstrated that a statistically significant proportion of CRSwNPs and AFRS participants reported sensitivity to wine. CONCLUSIONS This analysis suggests that there is an association between symptom exacerbation in response to food products with higher potential salicylate content, specifically wine, in CRS patients both with and without nasal polyposis when compared to controls, but especially in the CRSwNPs and AFRS phenotypes. Further studies are needed to detail if this relationship represents a causal relationship to dietary salicylate. The data present the possibility that a wider group of CRS patients may elicit salicylate sensitivity than those with known N-ERD.

Validation of the olfactory disorders questionnaire for English-speaking patients with olfactory disorders. Clin Otolaryngol 2019; 44:715-728. [PMID: 31038840 DOI: 10.1111/coa.13351] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2019] [Revised: 03/31/2019] [Accepted: 04/18/2019] [Indexed: 11/28/2022]
Abstract
OBJECTIVES To adapt the existing German language olfactory disorders questionnaire for use with English-speaking patients. To validate the adapted version for routine clinical use. DESIGN The translated version of the original German questionnaire was revised with a patient and a clinician to reflect British language and culture. Patients attending an olfactory dysfunction clinic were recruited to perform the adapted questionnaire on two occasions at least 1 month apart. Additional online participants completed the questionnaire via the charity Fifth Sense. MAIN OUTCOME MEASURES Retest reliability of the English olfactory disorders questionnaire (eODQ) in affected patients including potential for redundancy in any of the included questions. Correlation of eODQ scores with Sniffin' Sticks scores. RESULTS Eighty-seven patients reporting olfactory dysfunction were recruited and had a mean age of 48 with 35% of them being male; 50 datasets were available for analysis. A total of 957 members of the charity entered responses into the online questionnaire; 699 responses could be scored with participants' mean age of 55 years and with 69% reporting as female. The eODQ score and Sniffin' Sticks threshold, discrimination and identification score at timepoint 1 were correlated to assess for concurrent validity, (r = -0.15, P = 0.17) and showed no significant correlation. Female participants had a significantly higher mean total eODQ score than men, 55.75 compared to 52.28 (P = 0.001). The average score was 54.7 (SD 13.5) with a range from 26 to 87. The internal consistency of the questionnaire was good with a Cronbach's alpha of 0.90 (confidence intervals 0.89, 0.91). CONCLUSIONS The results of this study support the use of the eODQ in a native English-speaking population and highlight the different distinctions between "objective" testing of olfaction with the Sniffin' Sticks test, and the patient reported impact of olfactory dysfunction on daily life. These two types of assessment can be easily administered in an outpatient setting and used in the assessment and management of olfactory dysfunction.

Abstract
OBJECTIVES To explore patient views and perspectives of current management of chronic rhinosinusitis (CRS) in primary and secondary care. DESIGN Semistructured qualitative telephone interviews as part of the MACRO programme (Defining best Management for Adults with Chronic RhinOsinusitis). SETTING Primary care and secondary care ear, nose and throat outpatient clinics in the UK. PARTICIPANTS Twenty-five patients consented to in-depth telephone interviews. Transcribed recordings were managed using NVivo software and analysed using inductive thematic analysis. RESULTS CRS has a significant impact on patients' quality of life, affecting their ability to work effectively, their social interactions and daily living. Patients seek help when symptoms become unmanageable, but can become frustrated with the primary care system with difficulties obtaining an appointment, and lack of continuity of care. Patients perceive that general practitioners can be dismissive of CRS symptoms, and patients often prioritise other concerns when they consult. Health system barriers and poor communication can result in delays in accessing appropriate treatment and referral. Adherence to intranasal steroids is a problem and patients are uncertain about correct technique. Nasal irrigation can be time-consuming and difficult for patients to use. Secondary care consultations can appear rushed, and patients would like specialists to take a more 'holistic' approach to their management. Surgery is often considered a temporary solution, appropriate when medical options have been explored. CONCLUSIONS Patients are frustrated with the management of their CRS, and poor communication can result in delays in receiving appropriate treatment and timely referral. Patients seek better understanding of their condition and guidance to support treatments decisions in light of uncertainties around the different medical and surgical options. Better coordinated care between general practice and specialist settings and consistency of advice has the potential to increase patient satisfaction and improve outcomes.

Abstract
OBJECTIVES To explore general practitioner (GP) and ears, nose and throat (ENT) specialist perspectives of current treatment strategies for chronic rhinosinusitis (CRS) and care pathways through primary and secondary care. DESIGN Semi-structured qualitative telephone interviews as part of the MACRO programme (Defining best Management for Adults with Chronic Rhinosinusitis) SETTING: Primary care and secondary care ENT outpatient clinics in the UK. PARTICIPANTS Twelve GPs and 9 ENT specialists consented to in-depth telephone interviews. Transcribed recordings were managed using NVivo software and analysed using inductive thematic analysis. MAIN OUTCOME MEASURES Healthcare professional views of management options and care pathways for CRS. RESULTS GPs describe themselves as confident in recognising CRS, with the exception of assessing nasal polyps. In contrast, specialists report common missed diagnoses (eg, allergy; chronic headache) when patients are referred to ENT clinics, and attribute this to the limited ENT training of GPs. Steroid nasal sprays provide the foundation of treatment in primary care, although local prescribing restrictions can affect treatment choice and poor adherence is perceived to be the causes of inadequate symptom control. Symptom severity, poor response to medical treatment and patient pressure drive referral, although there is uncertainty about optimal timing. Treatment decisions in secondary care are based on disease severity, polyp status, prior medical treatment and patient choice, but there is major uncertainty about the place of longer courses of antibiotics and the use of oral steroids. Surgery is regarded as an important treatment option for patients with severe symptoms or with nasal polyps, although timing of surgery remains unclear, and the uncertainty about net long-term benefits of surgery makes balancing of benefits and risks more difficult. CONCLUSIONS Clinicians are uncertain about best management of patients with CRS in both primary and secondary care and practice is varied. An integrated care pathway for CRS is needed to improve patient management and timely referral.

Prevalence of asthma, aspirin sensitivity and allergy in chronic rhinosinusitis: data from the UK National Chronic Rhinosinusitis Epidemiology Study. Respir Res 2018; 19:129. [PMID: 29945606 PMCID: PMC6020303 DOI: 10.1186/s12931-018-0823-y] [Citation(s) in RCA: 69] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2018] [Accepted: 06/08/2018] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a common disorder associated with other respiratory tract diseases such as asthma and inhalant allergy. However, the prevalence of these co-morbidities varies considerably in the existing medical literature and by phenotype of CRS studied. The study objective was to identify the prevalence of asthma, inhalant allergy and aspirin sensitivity in CRS patients referred to secondary care and establish any differences between CRS phenotypes. METHODS All participants were diagnosed in secondary care according to international guidelines and invited to complete a questionnaire including details of co-morbidities and allergies. Data were analysed for differences between controls and CRS participants and between phenotypes using chi-squared tests. RESULTS The final analysis included 1470 study participants: 221 controls, 553 CRS without nasal polyps (CRSsNPs), 651 CRS with nasal polyps (CRSwNPs) and 45 allergic fungal rhinosinusitis (AFRS). The prevalence of asthma was 9.95, 21.16, 46.9 and 73.3% respectively. The prevalence of self-reported confirmed inhalant allergy was 13.1, 20.3, 31.0 and 33.3% respectively; house dust mite allergy was significantly higher in CRSwNPs (16%) compared to CRSsNPs (9%, p < 0.001). The prevalence of self- reported aspirin sensitivity was 2.26, 3.25, 9.61 and 40% respectively. The odds ratio for aspirin sensitivity amongst those with AFRS was 28.8 (CIs 9.9, 83.8) p < 0.001. CONCLUSIONS The prevalence of asthma and allergy in CRS varies by phenoytype, with CRSwNPs and AFRS having a stronger association with both. Aspirin sensitivity has a highly significant association with AFRS. All of these comorbidities are significantly more prevalent than in non-CRS controls and strengthen the need for a more individualised approach to the combined airway.

Abstract
Background Changes in nasal physiology have been observed during pregnancy and the menstrual cycle. The role of female hormones in these changes is unclear. The aim is to investigate the effect of the modern combined oral contraceptive pill (COCP). Methods Eleven women were recruited from a family planning clinic. Anterior rhinoscopy, peak inspiratory flow rate, acoustic rhinometry, anterior rhinomanometry, mucociliary clearance time, and rhinitis quality-of-life questionnaire (RQLQ) scores were recorded at days 1 and 14 pre- and post-COCP. Results Increased nasal obstruction midcycle pre-COCP, with significant differences for anterior rhinoscopy (p = 0.001) and peak inspiratory flow rate (p = 0.022), was found. No statistical difference was shown between pre- and post-COCP results apart from day 1 anterior rhinoscopy findings (p = 0.05). Conclusion The modern COCP has no significant effect on nasal physiology.

Abstract
BACKGROUND This study is part of the Chronic Rhinosinusitis Epidemiology Study (CRES). The overarching aim is to determine factors that influence the onset and severity of chronic rhinosinusitis (CRS). The aim of this analysis is to determine whether those with CRS are more likely to report psychiatric morbidity and in particular mood disturbance compared with healthy controls. METHODS CRES consists of a study-specific questionnaire regarding demographic and socioeconomic factors and past medical history as well as a nasal symptom score (SNOT-22) and SF-36 (QoL - quality of life tool). Both of these tools contain mental health or emotional well-being domains. Participants were specifically asked whether they had ever consulted with their General Practitioner for anxiety or depression. Questionnaires were distributed to patients with CRS attending ENT outpatient clinics at 30 centres across the United Kingdom from 2007-2013. Controls were also recruited at these sites. Patients were divided into subgroups of CRS according to the absence/presence of polyps (CRSsNPs/CRSwNPs) or allergic fungal rhinosinusitis (AFRS). RESULTS Consultations with a family physician for depression or anxiety were higher amongst those with CRS than controls, but this was only significant for those with CRSsNPs. Odds ratio (OR) for CRSsNPs vs controls: 1.89; OR for CRSwNPs: 1.40. Patients with CRS showed significantly higher mental health morbidity than controls across the mental health and emotional wellbeing domains of the SF-36 and SNOT-22. Mean difference in the mental health domain of SF-36 was 8.3 for CRSsNPs and 5.3 for CRSwNPs. For the emotional domain of SNOT-22, differences were 7.7 and 6.3 respectively. CONCLUSIONS Depression and anxiety are significantly more common in patients with CRS compared to healthy controls, especially in those with CRSsNPs. This added mental health morbidity needs consideration when managing these patients in primary and secondary care settings.

Abstract
OBJECTIVES Direct comparison of different diseases allows clinicians and researchers to place the burden of symptoms and impact on quality of life of each condition in context. Generic health-related quality-of-life assessment tools allow such analysis, and limited data are available for British patients with chronic rhinosinusitis. DESIGN As part of a larger feasibility study, patients underwent baseline assessment using the SNOT-22, SF-12 and EQ-5D-5L tools. Data were analysed using Microsoft Excel and algorithms available for the analysis of the later two tools. We plotted EQ-5D-5L VAS and utility scores and SF-12 MCS and PCS scores separately against SNOT-22 scores and quantified associations using bivariate ordinary least squares regression analysis. SETTING Patients were prospectively recruited from six UK outpatient clinics. PARTICIPANTS Adult patients with chronic rhinosinusitis without nasal polyps (CRSsNPs). MAIN OUTCOME MEASURES Baseline SNOT-22, SF-12 and EQ-5D-5L scores. RESULTS Fifty-two adults were recruited with a mean age of 55 years, 51% were male. The mean SNOT-22 score was 43.82. Mental and physical component scores of the SF-12 were 46.53 and 46, respectively. Mean index score computed form the EQ-5D-5L was 0.75. Worse (higher) SNOT-22 scores were associated with lower EQ-5D-5L VAS and utility scores and SF-12 MCS and PCS scores. CONCLUSION The EQ-5D-5L suggests that British CRSsNPs patients are negatively impacted with regards to quality of life. We found the SF-12 to be less sensitive and conclude that the EQ-5D-5L tool is a quick and accessible method for assessing QOL in order it can be compared with other disease states.

Abstract
OBJECTIVES Previous research has suggested that sodium citrate improves hyposmia by decreasing mucus calcium levels in the nose. This study aimed to confirm or refute this effect in a single application and assess potential side-effects. DESIGN Study design was a randomised double-blind controlled trial of sodium citrate nasal spray (intervention) vs sterile water (control). Fifty-five patients with non-conductive olfactory loss were randomised to receive the intervention or placebo. SETTING Tertiary care clinic. MAIN OUTCOME MEASURES The primary outcome measure was improvement in measured olfactory thresholds for phenyl ethyl alcohol (PEA) over 2 hours. Other outcome measures assessed were improvement in olfactory thresholds in 1-butanol, eucalyptol and acetic acid; number of responders with a clinically relevant response in each arm; and adverse effects. RESULTS A significant effect was seen in the intervention arm for PEA and for 1-butanol and eucalyptol when compared to the control arm (P<.05); 32% of the intervention arm responded in terms of improved sensitivity towards some of the odours. Minor adverse effects noted included sore throat, nasal paraesthesia, slight rhinorrhoea and itching. The duration of effect of the citrate is transient, peaking at 30-60 minutes after application. CONCLUSIONS Sodium citrate yields some potential as a treatment for non-conductive olfactory loss; however, these findings require corroboration in further clinical trials looking at longer term regular use of the spray as a viable therapeutic option for patients where it would be applied at frequent intervals such as before mealtimes.

Abstract
BACKGROUND Given the differences in pathophysiology between allergic fungal rhinosinusitis (AFRS) and other chronic rhinosinusitis (CRS) subgroups, it remains unclear about whether these patients respond differently to a combination of surgical and medical treatments. OBJECTIVE To evaluate differences in quality-of-life (QoL) outcomes for a cohort of patients who underwent endoscopic sinus surgery (ESS) for CRS. METHODS This retrospective review included patients with CRS who underwent ESS between 2010 and 2013. QoL was measured by using the 22-item Sino-Nasal Outcome Test (SNOT-22). Variables collected included baseline demographics, SNOT-22 scores before ESS and at 1, 3, 6, 9, and 12 months after ESS. Groups tested were CRS with nasal polyposis, CRS without nasal polyposis (CRSsNP), and patients with AFRS. A linear mixed- effects regression model was used to calculate the adjusted mean QoL differences. RESULTS Among the 250 patients included, 61.6% had CRS with nasal polyposis (n = 154), 28.8% had CRSsNP (n = 72), and 9.6% had AFRS (n = 24). Significant differences were seen in SNOT-22 scores between pre- and postoperative visits and between the etiologic subgroups (p < 0.001). Multivariate analysis revealed significantly greater improvement in QoL for patients with AFRS in comparison with those with CRSsNP at the 9-month follow-up (change in SNOT-22 score, 22.6 [95% confidence interval, 1.2-44.1]; p < 0.0) and the 12-month follow-up (change in SNOT-22 score, 20.2 [95% confidence interval, 0.5-39.9]; p < 0.04). CONCLUSIONS Patients with AFRS experienced a more-prolonged QoL benefit from surgical and targeted medical intervention compared with those with CRSsNP, which may reflect the severity of inflammation that they presented with compared with other CRS subtypes.

Abstract
Background: It is recognized that patients who undergo endoscopic sinus surgery (ESS) do not always achieve control of their disease. The causes are multifactorial; variations in surgical practice have been identified as possible factors in refractory disease. Objective: To reflect on the frequent anatomic findings of patients with chronic rhinosinusitis (CRS) who require revision ESS. Methods: A retrospective review of patients who required revision ESS at a tertiary institution over a 3-year period. Patients for whom maximal medical therapy failed for CRS underwent computed tomography of the paranasal sinuses and image-guided surgery. Surgical records of anatomic findings were reviewed and analyzed. Results: Over 3 years, a total of 75 patients underwent revision procedures, 28% of all ESS performed in the unit. The most frequent finding was a residual uncinate process in 64% of the patients (n = 48); other findings included a maxillary antrostomy not based on the natural ostium of the maxillary sinus in 47% (n = 35), an oversized antrostomy in 29% (n = 22), resected middle turbinates in 35% (n = 26), middle meatal stenosis in 15% (n = 11), synechiae in 29% (n = 22), and osteitic bone that required drilling in 13% (n = 10). Conclusion: Surgical technique can give rise to anatomic variations that may prevent adequate mucociliary clearance and medication delivery, which leads to failure in ESS in patients with CRS. This study demonstrated the surgical findings encountered in revision ESS that should be highlighted in the training of Ear, Nose and Throat surgeons to help prevent primary failure and reduce health care costs.

Abstract
OBJECTIVES There is currently conflicting level 1 evidence in the use of long-term antibiotics for chronic rhinosinusitis without nasal polyps. The primary aim of this feasibility study was to optimise future randomised trial design by assessing recruitment and retention of patients alongside providing preliminary data on symptomatic control. DESIGN Prospective, multicentre feasibility (cohort) study with all patients receiving macrolide therapy for 12 weeks and a further subsequent 12-week follow-up. Participants received a 12-week course of clarithromycin 250 mg alongside twice daily topical mometasone and nasal douching. Primary outcomes focused on recruitment, retention and compliance. Clinical and quality-of-life outcomes measures were also recorded. SETTING Patients were prospectively recruited from six UK outpatient clinics. PARTICIPANTS Adult patients with chronic rhinosinusitis without nasal polyps and no prior endoscopic sinus surgery underwent baseline assessment and then follow-up at 3 and 6 months. MAIN OUTCOME MEASURES Six-month recruitment and retention data. RESULTS Over 13 months, 55 adults were recruited from five centres. Four patients declined participation. 75% of patients were retained within the study. Dropouts included one medication contraindication, three unable to tolerate medication and 10 not attending full follow-up. Sino Nasal Outcome Test-22 and endoscopic scores showed statistically significant improvement. No other clinical or quality-of-life assessment improvements were seen. CONCLUSION Retention and recruitment to a trial using long-term clarithromycin to treat chronic rhinosinusitis without nasal polyps is achievable and this data will support a future randomised controlled trial. The study provides vital insight into trial design, thus informing UK research networks and rhinology researchers internationally.

Abstract
OBJECTIVE The aim of this analysis is to explore views of patients with chronic rhinosinusitis (CRS) about of the aetiology of their respiratory symptoms and the relationship between upper and lower respiratory symptoms. METHODS This study is part of a larger mixed methods study investigating the epidemiology of CRS, which comprises a questionnaire study of patients with CRS and controls and a qualitative study of 21 patients with CRS. Semi structured qualitative interviews were undertaken with these patients; 11 males and 10 females. Twelve patients had asthma. Patients were recruited with a tertiary outpatient rhinology clinic. Interviews were transcribed verbatim and analysed using thematic analysis, using Nvivo software (QSR International, Melbourne, Australia). Several important and recurring themes were highlighted. RESULTS Patients described many perceived triggering factors and an interaction between upper and lower respiratory tract symptoms. They felt that their symptoms could be managed more holistically. CONCLUSIONS Concerns about triggers of respiratory symptoms and interactions between upper and lower respiratory symptoms are of significant concern to patients. These should be appropriately managed and acknowledged in formal treatment pathways, for example, through the use of combined ENT/respiratory clinics.

Abstract
Objectives: This study is part of the Chronic Rhinosinusitis Epidemiology Study (CRES). The overarching aim is to determine factors that influence the onset and severity of chronic rhinosinusitis (CRS).The aim of this analysis is to determine the number of patients consulting with their family physician about anxiety or depression among those with CRS and controls. Methods: CRES is a mixed methods study of patients with CRS including qualitative interviews and study-specific questionnaires. This analysis considers only the questionnaires. These included comprehensive questions about demographic and socioeconomic factors and past medical history as well as SNOT-22 (nasal symptom score) and SF-36 (quality of life tool). Questionnaires were distributed to patients with CRS attending general ENT and rhinology clinics within the National Health Service and private sector and to a control population across many centers in the United Kingdom from 2004 to 2013. Results: A total of 1519 participants, including 57 with AFRS (allergic fungal rhinosinusitis), 659 CRSwNP (with nasal polyps), 577 CRSsNP (without nasal polyps), and 236 controls. Self-reported consultation with family physician for depression was 9 out of 57 (15.8%), 132 out of 659 (20.0%), 142 out of 577 (24.6%), and 36 out of 226 (15.9%), respectively. P < .02 for differences between participant subgroups. For anxiety: AFRS 10 out of 57 (17.5%), CRSwNP 105 out of 659 (15.9%), CRSsNP 130 out of 577 (22.5%), controls 39 out of 236 (16.5%), P = .04 between groups. Conclusions: There are differences in rates of consulting with family physicians for depression and anxiety disease between those with different types of CRS and controls; those with CRS without polyps were most likely to have consulted. This may influence management strategies for patients with different nasal pathologies.

Abstract
Objectives: There is currently conflicting level 1 evidence in the use of long-term antibiotics for chronic rhinosinusitis. The primary aim of this study was to look at recruitment and retention of patients in preparation for a formal trial. The aim of this paper is to describe the preliminary outcomes in terms of symptomatic relief in patients with CRSsNP. Methods: Adult patients fulfilling the EPOS criteria for CRSsNPs with no prior surgery were recruited in 6 UK centers during 2013. Participants received a 12-week course of clarithromycin 250 mg alongside topical mometasone and nasal douching, all twice daily. Follow-up was at 3 months and 6 months. For the purpose of this analysis, the Sinonasal Outcome Test (SNOT-22) score was recorded at baseline and both follow-up assessments. Results: Preliminary data from 29 patients at 3 months and 24 patients at 6 months showed significant symptomatic improvement in mean SNOT-22 scores on paired t tests at 3 months (40.4 to 33.7, P = .026), which was sustained at 6 months (30, P = .02). The number of subjects showing ≥9 point reduction in SNOT-22 scores was 45% (n = 13), increasing to 58% at 6 months (n = 14). Nine patients have been listed for surgery to date. Conclusions: While the results here do not have the power of the full randomized controlled trial, the findings suggest that long-term macrolides have the potential to achieve significant symptomatic reduction in approximately 50% of patients with CRSsNPs.

Abstract
Objectives: Long-term follow-up of 1045 patients with chronic rhinosinusitis with nasal polyposis (CRSwNPs) in the national Sinonasal Audit demonstrated that at 5 years 20.6% of patients had undergone revision surgery. The aim of this study was to see if the Chronic Rhinosinusitis Epidemiology Study (CRES) data reflected a continued burden of revision surgery in patients with CRSwNPs. Methods: A prospective questionnaire-based study at 30 sites around the UK of patients with CRS presenting to secondary care between October 2007 and September 2013. This paper presents a specific analysis of patients with CRS who reported undergoing sinus surgery. Results: A total of 651 patients with CRSwNPs, 553 with CRSsNPs, and 45 with AFRS were included in the CRES. 365 (57%) of patients with CRSwNPs/AFRS reported undergoing endoscopic nasal polypectomy (ENP) in which 175 (25% or 48% of surgical cases) reported having received more than one ENP. The mean number of ENPs per patient in the revision group was 3.3 with a range of 2 to 30. Only 27.9% of patients reported concurrent endoscopic sinus surgery (n = 102). For comparison, patients with CRSsNPs reported ESS in 13% of cases with only 17% of those surgical cases reporting multiple procedures (chi-squared P < .001). Conclusions: This study demonstrated a significantly higher burden of both primary and revision surgery to the health care system for patients with CRSwNPs. Extrapolation of these findings to the HES data for 2011 and 2012 would suggest a bill of approximately £5.3 million per year spent on revision surgery.

Abstract
Objectives: This analysis uses data from the Chronic Rhinosinusitis Epidemiology Study (CRES). The overarching aim of CRES is to determine factors which influence the onset and severity of chronic rhinosinusitis (CRS). Sino-Nasal Outcome Test (SNOT-22) is a widely used score for nasal symptoms in many ENT clinics internationally, although there are few data characterizing SNOT-22 scores for a normal population. The aim of this analysis is to establish a dataset of normal values for SNOT-22 in a British population. Methods: Study-specific questionnaires including demographic and socioeconomic factors and past medical history as well as SNOT-22 and SF-36 were distributed to patients with CRS attending ENT clinics and to a control population across several centers in the United Kingdom. This analysis considered just the control population. Controls had no self-reported nasal problems in the past, no chronic conditions undergoing active treatment, and no hospital admissions in the preceding 12 months. Results: A total of 1529 participants were recruited; 57 with AFRS (allergic fungal rhinosinusitis), 659 CRSwNP (with nasal polyps), 577 CRSsNP (without nasal polyps), and 236 controls. Age range was 18 to 98 years. Two hundred thirteen controls included sufficient information to calculate SNOT-22 score. Score range was 0 to 85; median 9, mean 13.4. Conclusions: SNOT-22 is an important tool for measuring the impact of nasal symptoms and evaluating effectiveness of treatments. Data for a large population without nasal problems will be invaluable in both clinical and academic settings. Further analysis will characterize SNOT scores for different types of CRS and subgroup analysis of different elements of SNOT-22.

Abstract
We present a case of long-standing unilateral cacosmia in a healthy 67-year-old man due to maxillary fungal infestation. Treatment with septoplasty had been attempted 10 years prior but no further investigation or management undertaken and symptoms continued. Subsequent MRI scan revealed significant opacification of the left maxillary sinus. This was readily amenable to treatment by balloon sinuplasty. This yielded viscous grey mucus which grew Scedosporium apiospermum. The case highlights the need for careful investigation of olfactory symptoms, including blood tests to exclude systemic causes, endoscopy and imaging where indicated.

Abstract
BACKGROUND Middle meatal spacers are commonly used following endoscopic sinus surgery to prevent post-operative bleeding and lateralization of the middle turbinates. The effects of nasal packing on post-operative sinonasal mucosal healing remain unknown in humans. OBJECTIVE This study aims to compare the histopathalogical effects of Merocel and Merocel covered with a finger glove on mucosal healing, and patients` discomfort immediately post-operatively after endoscopic sinus surgery and at removal of the nasal packing. METHODS Thirty-seven patients with chronic rhinosinusitis undergoing bilateral endoscopic sinus surgery were enrolled in a prospective study. Patients were randomized and blinded to receive Merocel middle meatal spacer (MMMS) in one nostril and finger glove Merocel middle meatal spacer (FGMMS) in the contra lateral side. Patients were seen on post-operative day 6, and completed a visual analogue score reporting the post-operative discomfort from nasal packing on each side. Following the removal of nasal packing, patients indicated which side caused more discomfort on removal. Biopsies were taken from the middle turbinates and sent to a blinded pathologist who scored the level of mucosal inflammation from 0 - 4. RESULTS There was no statistically significant difference between MMMS and FGMMS in regards to their effect on sinonasal mucosal inflammation and discomfort post-operatively. A statistically significant difference was noted with respect to discomfort at removal with the uncovered Merocel more likely to cause discomfort when compared to the Merocel covered in a glove finger. CONCLUSION MMMS and FGMMS are equivalent in the amount of sinonasal mucosal inflammation and discomfort post endoscopic sinus surgery. However, the main advantage of the FGMMS was a significant reduction in pain on removal when compared with the MMMS.

Abstract
BACKGROUND The existing Kupferberg post-operative endoscopic staging system for allergic fungal rhinosinusitis (AFRS) has 4 stages (0-3) based on the `global` appearance of one side of the nose. Patients may however show visual improvement and yet remain at the same stage due to persistence in one sinus cavity, thus making the staging system ineffective. The aim of this study was to validate a new system that allows greater sensitivity in characterising the inflammation seen endoscopically. METHODOLOGY A series of endoscopy videos of 50 patients with AFRS were retrospectively staged using a new ten-grade system, scoring each sinus cavity (maxillary, ethmoid, frontal and sphenoid) from 0-9 for increasing mucosal oedema and 1 point for the presence of fungal mucin giving a maximum score of 40 for each side of the nose. To assess reliability, 4 independent rhinologists were also asked to score the videos using the new system. RESULTS A greater variety in the spectrum of mucosal disease was demonstrated with the new system allowing for a more descriptive analysis of its severity and its response, or lack of, to treatment. The inter-class correlation between the 6 total observers was 0.86 (95% CI: 0.83, 0.92). CONCLUSION Use of the new staging system provides a more sensitive tool for following patients` progress post-operatively in allergic fungal rhinosinusitis and in determining their response to treatment.

Abstract
Objective: Validate the applicability of Sniffin’ Sticks in a UK population. These pen-like odor dispensing devices are used to assess threshold, discrimination, and identification. Odor identification is strongly dependent on familiarity with the odors and has an important cultural component, which has limited the usefulness of other validated tests. Method: A prospective study of 63 subjects, 24 healthy volunteers with a reported normal sense of smell, and 39 patients with an impaired sense of smell presenting either at a rhinology or an olfactory disorder clinic. Each subject’s olfactory function was assessed using the Sniffin’ Stick test. Results: The mean age of the subjects tested was 46.7 years; 40 female and 23 male. In the patient group, 30 were hyposmic and 9 anosmic. In the healthy volunteers group, all subjects were normosmic. The mean TDI score for patients and healthy volunteers was 21.06 (range, 8-30.5) and 33.73 (range, 29.25-37.75) respectively. Mean identification score in the 2 groups was 8.84 (range, 1-15) for patients (range) and 13.69 (range, 11-16) for healthy volunteers. Conclusion: In our sample of the UK population the TDI and odor identification scores for healthy volunteers and patients with olfactory disorders are comparable with the normative data published on large samples of European populations. Discussion of commonly mistaken odors in the odor identification test is undertaken.

Abstract
OBJECTIVES To examine the yield and resistance profile of pathogens in chronic rhinosinusitis (CRS) patients receiving culture-directed management and to pay particular attention to the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in this population. STUDY DESIGN Retrospective review of a CRS microbiology database. PARTICIPANTS Consecutive CRS patients seen at the St. Paul's Sinus Centre between June 2007 and August 2008. SETTING Canadian tertiary sinus centre. MAIN OUTCOME MEASURE To determine the pathogens isolated, the frequency of these pathogens, and their resistance profiles. RESULTS The most common bacterial pathogens isolated were Staphylococcus aureus, accounting for 39% of cultured samples, followed by Haemophilus influenzae (29%), Pseudomonas aeruginosa (15%), Streptococcus pneumoniae (12%), and Moraxella catarrhalis (11%). Only three cases of MRSA were found, one in a patient with cystic fibrosis. CONCLUSION MRSA does not appear to pose a significant risk of morbidity in our patient population. However, ongoing concern regarding the increasing prevalence of S. aureus and antimicrobial resistance in chronic sinonasal disease highlights the importance of using culture-directed antimicrobial therapy with the goal of minimizing future resistance patterns.

Abstract
OBJECTIVE To determine the incidence of positive cultures from contaminated nasal cartilage and to demonstrate the effectiveness of antibiotic irrigation as a means of sterilization. DESIGN A prospective study. SETTING Tertiary referral centre. METHODS Nasal septal cartilage was harvested during routine endoscopic septoplasties. The harvested cartilage was then dropped on the floor for 60 seconds. The cartilage was then divided into four equal portions, which were then divided into four experimental groups: (1) untreated, (2) normal saline soak for 60 seconds, (3) 40 mg/mL gentamicin solution soak for 60 seconds, and (4) 300 seconds. All specimens were sent for bacterial culture and sensitivity, along with nasal swabs and floor swabs. The incidence of bacterial contamination in the different groups was analyzed using the McNemar hypothesis. MAIN OUTCOME MEASURES Correlation between bacterial culture results and treatments of contaminated nasal septal cartilages. RESULTS Thirty-two patients were enrolled in this study. Thirty-one percent of the untreated specimens had bacterial contamination. Thirty-one percent of the saline-soaked specimens had significant bacterial growth. Bacterial growth was not observed in any of the specimens treated with gentamicin irrigation for 60 seconds (absolute reduction of 31%); one specimen (3%) in the 300 seconds gentamicin group had a positive culture. A correlation of 70% was observed in the bacterial growth observed in the swab of the operating room floor and the untreated cartilage. CONCLUSIONS When no other options are available, this study demonstrates that cartilage dropped on the floor can be decontaminated by washing with gentamicin.

Abstract
OBJECTIVES To demonstrate that computer-assisted endoscopic management of inverted papillomas yields excellent long-term results in terms of preventing recurrence and minimizing significant morbidity and mortality. METHODS A retrospective chart review of patients who are being followed up for tumour recurrence or have undergone tumour removal between 2000 and 2008. All cases were undertaken using the GE Instatrak 3500+ navigation system. RESULTS Inverted papillomas are the most common tumour managed endoscopically (57% of all sinonasal tumours) with 76 patients seen over the last 8 years. Approximately 50% of these cases had undergone previous surgery in another centre where the tumour was either not recognized or the resection was incomplete. Twentynine percent of these patients had a recurrence but only three required a revision procedure using an open approach; otherwise recurrences were successfully managed endoscopically. Endoscopic recurrence during the first half was 32% (versus 14% for open procedures), dropping to a recurrence rate of 11% in the latter period. CONCLUSIONS Endoscopic management of inverted papillomas allows good control of the disease and avoids unnecessary morbidity associated with open procedures. Although there is a higher initial recurrence rate, these recurrences can be successfully managed endoscopically, and computer navigation can be a useful adjunct in achieving this.
