Features of ENT Cases in the Emergency Department of a Tertiary Hospital in Greece: A Prospectively Driven Data Collection Study.

Primary healthcare is the pillar of a well-functioning healthcare system. General practitioners (GPs) should have a broad skillset to cope with the various conditions they encounter in everyday practice. Ear, nose, and throat (ENT) cases are some of the most common reasons for seeking care. The study aimed to define the frequency and type of ENT disorders seen in the emergency department of a tertiary hospital in Greece. All patients examined by an ENT specialist in the emergency department setting, within a year, were recorded, as well as all referrals from private practice or primary care facilities. From September to December 2021, data were collected from patients who agreed to complete a two-minute survey, namely, the Generalized Anxiety Disorder Scale (GAD-2) questionnaire. During the study year, 4542 cases were documented, from which the most common conditions listed were external otitis (6.9%/314), epistaxis (6.7%/305), and impacted earwax (5.7%/261). The diagnoses that led to hospitalization were 336 and the most common were peritonsillar abscess (16.4%/55), epistaxis (8.0%/27), and facial nerve paralysis (7.4%/25). Referrals from GPs working in the public sector represented more than the half of the total. There was a significant correlation between an increased number of hospital visits and an increased GAD-2 score, in the semester before the current visit (p < 0.001). Referrals to ENT specialists represent around 5% of all cases examined, and about 8% of all visits required hospitalization. Interdisciplinary clinical and research investment into GP training is compulsory to regulate ENT referrals by GPs.

Multimorbidities in Allergic Rhinitis-Current Evidence from Epidemiological Studies, Treatment Trials, and Molecular Data.

PURPOSE OF REVIEW: Given that allergic rhinitis (AR) commonly coexists with other diseases, the present narrative review attempts a brief presentation of current theories on multimorbidities in relation to phenotypes, genotypes, age, and treatment responses with the term "multimorbidities" indicating the uncertainty regarding the primary defect, organ, or pathophysiologic mechanism involved. RECENT FINDINGS: Though age-related manifestations allow for the generation of several hypotheses on AR's specific mechanisms, the various theories regarding the initiation or the aggravation of atopic disorders have yet to be proved. Multimorbid AR seems to have a different genetic basis from "stand-alone" AR as well a more severe phenotype. Most studies on the treatment of AR and its multimorbidities focus on allergen immunotherapy, which improves the atopic symptoms and may play a preventive role in the onset of new allergen sensitizations. The use of biological factors may also have a beneficial effect, even though it has currently been approved only for some comorbidities of AR, such as asthma. Employing the use of phenotypes and genotypes concerning multimorbidity broadens current knowledge, but further research is needed to develop diagnostic, stratificational, and predictive algorithms for single and multimorbid allergic diseases (Fig. 1). The real-time data obtained by mobile apps and the new insights on the pathophysiology of AR and its comorbidities will permit both timed preventive measures and better individualized and effective antiallergic treatment.

Atopic children are more susceptible to viral respiratory infection at the age of 2-5 years old.

Background: The susceptibility of the atopic population to respiratory infections (RI) has not been fully elucidated. This susceptibility is attributed to the immune dysregulation that characterizes atopic diseases. Although, the exact mechanisms involved are not fully understood, there is evidence that shows that the maturation of innate immunity progresses differently in patients with atopy. Objective: The aim of the study was to evaluate the susceptibility to viral RIs (VRI) based on the number and duration of them in different age groups in subjects with atopy and subjects without atopy. Methods: Seventy-eight subjects (39 healthy and 39 with atopy) were included in the study. All the subjects were evaluated by a specialist and defined as being atopic if they had a clinical history and/or symptoms compatible with any allergic diseases and relevant sensitizations. Epidemiologic data were recorded based on a standardized questionnaire, which included recording habits, conditions, and living environment as well as the history of viral infections during the last year. Results: In our population, children with atopy were found to be more susceptible to viral RIs than children without atopy (p = 0.02), whereas there was no difference in susceptibility between healthy adults and adults with atopy (18-45 years old). More specifically, the atopic age group 2-5 years old showed the higher susceptibility to VRIs. Conclusion: This study provided evidence that children with atopy, especially at ages 2-5 years old, had more numerically and prolonged RIs than did the subjects without atopy. These clinical findings support the hypothesis of distracted maturation of innate immunity in subjects with atopy.

Clinical Controversy Surrounding the Differential Diagnosis of Branchiogenic Carcinoma.

Clinical evaluation, differential diagnosis, and management of a neck mass constitute commonly encountered problems for the head and neck surgeon. An asymptomatic neck mass in adults may be the only clinical sign of head and neck cancer. A 50-year-old female patient presented with a painless, slowly enlarging, left lateral neck lump. Ultrasonography described a possible lymph node with cystic degeneration, and fine needle aspiration biopsy only detected atypical cells of squamous epithelium. An open biopsy under general anesthesia was performed. Histopathological findings suggested the diagnosis of lymph node infiltration by squamous cell carcinoma of an unknown primary site, but differential diagnosis also included branchiogenic carcinoma arising in a branchial cleft cyst. A diagnostic algorithm for metastatic squamous cell carcinoma of an unknown primary site was followed, including positron emission tomography with computed tomography. The patient underwent panendoscopy and bilateral tonsillectomy, and an ipsilateral p16 positive tonsillar squamous cell carcinoma was detected. Further appropriate management followed. The existence of true branchiogenic carcinoma is controversial. When such a diagnosis is contemplated, every effort should be made to detect a possible primary site. Branchiogenic carcinoma, if exists at all, remains a diagnosis of exclusion.

White Paper on European Patient Needs and Suggestions on Chronic Type 2 Inflammation of Airways and Skin by EUFOREA.

Background: Type 2 inflammation underlies the chronicity of disease in subgroups of patients with asthma, chronic rhinosinusitis with nasal polyps (CRSwNP) and atopic dermatitis (AD), that often co-exist. Although several studies have investigated the unmet needs of asthma, AD and CRSwNP as such, little is known about the similarities and differences in experiences and perspectives of the current management of patients with comorbid Type 2 inflammatory diseases. Aims: To improve insight into the common and organ-specific needs of patients with Type 2 inflammation and comorbidities, allowing the formulation of recommendations to better address these needs in the future. Methodology: This qualitative study was conducted between July 2021 and December 2021 using semi-structured face-to-face or telephone interviews with patients suffering from year-long severe chronic Type 2 inflammation and at least one co-morbid inflammatory condition. Seven participating academic centers in Europe interviewed asthma (Copenhagen and Leuven), CRSwNP (London, Amsterdam and Crete) and/or AD (Oldenburg and Zurich) patients on patient characteristics, disease severity, shortcomings of current care pathways and suggestions for improvement of care. Transcripts were analyzed using an inductive thematic analysis approach. Results: Eighty-one patients with severe Type 2 inflammation and comorbidities were interviewed. Similar needs were recognized by patients with Type 2 inflammation, with both a lack of coordination in care and a lack of a real cure reported as being most frustrating. However, several needs are specific to asthma, CRSwNP and AD. Suggestions for improvement of care were generic across diseases, such as the implementation of a multidisciplinary approach, the improved facilitation of access to better treatments, the increase of general awareness on disease burden, and better educational programs for healthcare providers and patients. Of note, patients with CRSwNP also stated the need for alternatives to sinus surgery, whereas patients with asthma requested better medical care to prevent exacerbations and patients with AD would warmly welcome the reimbursement of emollients. Conclusion: Patients with asthma, CRSwNP and AD have shared unmet needs that need to be addressed by physicians, the academic community and health policy makers. This survey provides unique recommendations made by patients for the implementation of better care.

Mometasone furoate and fluticasone furoate are equally effective in restoring nasal epithelial barrier dysfunction in allergic rhinitis.

Tight junction defects (TJ) have been associated with a defective epithelial barrier function in allergic rhinitis (AR). Intranasal corticosteroids are potent drugs frequently used to treat AR and are shown to restore epithelial integrity by acting on TJs and by reducing type 2 cytokine production. However, the effect of different classes of intranasal corticosteroids on the epithelial barrier has not been studied. Therefore, we compared the effect of 2 intranasal corticosteroids, ie, fluticasone furoate (FF) and mometasone furoate (MF) on epithelial barrier function. Both FF and MF similarly increased trans-epithelial electrical resistance of primary nasal epithelial cell cultures from AR patients. In a house dust mite-induced allergic asthma mouse model, FF and MF had similar beneficial effects on fluorescein isothiocyanate-dextran 4 kDa mucosal permeability, eosinophilic infiltration and IL-13 levels. Both molecules increased mRNA expression of the TJ proteins occludin and zonula occludens-1, thereby restoring epithelial barrier function. Lastly, we showed that long-term FF treatment also increased expression of occludin in AR patients compared to controls. In conclusion, both FF and MF effectively restore epithelial barrier function by increasing expression of TJ proteins in AR patients.

Validity, reliability, and responsiveness of daily monitoring visual analog scales in MASK-air®.

BACKGROUND: MASK-air® is an app that supports allergic rhinitis patients in disease control. Users register daily allergy symptoms and their impact on activities using visual analog scales (VASs). We aimed to assess the concurrent validity, reliability, and responsiveness of these daily VASs. METHODS: Daily monitoring VAS data were assessed in MASK-air® users with allergic rhinitis. Concurrent validity was assessed by correlating daily VAS values with those of the EuroQol-5 Dimensions (EQ-5D) VAS, the Control of Allergic Rhinitis and Asthma Test (CARAT) score, and the Work Productivity and Activity Impairment Allergic Specific (WPAI-AS) Questionnaire (work and activity impairment scores). Intra-rater reliability was assessed in users providing multiple daily VASs within the same day. Test-retest reliability was tested in clinically stable users, as defined by the EQ-5D VAS, CARAT, or "VAS Work" (i.e., VAS assessing the impact of allergy on work). Responsiveness was determined in users with two consecutive measurements of EQ-5D-VAS or "VAS Work" indicating clinical change. RESULTS: A total of 17,780 MASK-air® users, with 317,176 VAS days, were assessed. Concurrent validity was moderate-high (Spearman correlation coefficient range: 0.437-0.716). Intra-rater reliability intraclass correlation coefficients (ICCs) ranged between 0.870 (VAS assessing global allergy symptoms) and 0.937 (VAS assessing allergy symptoms on sleep). Test-retest reliability ICCs ranged between 0.604 and 0.878-"VAS Work" and "VAS asthma" presented the highest ICCs. Moderate/large responsiveness effect sizes were observed-the sleep VAS was associated with lower responsiveness, while the global allergy symptoms VAS demonstrated higher responsiveness. CONCLUSION: In MASK-air®, daily monitoring VASs have high intra-rater reliability and moderate-high validity, reliability, and responsiveness, pointing to a reliable measure of symptom loads.

Review of Rhinitis: Classification, Types, Pathophysiology.

Rhinitis describes a pattern of symptoms as a result of nasal inflammation and/or dysfunction of the nasal mucosa. It is an umbrella entity that includes many different subtypes, several of which escape of complete characterization. Rhinitis is considered as a pathologic condition with considerable morbidity and financial burden on health care systems worldwide. Its economic impact is further emphasized by the fact that it represents a risk factor for other conditions such as sinusitis, asthma, learning disabilities, behavioral changes, and psychological impairment. Rhinitis may be associated with many etiologic triggers such as infections, immediate-type allergic responses, inhaled irritants, medications, hormonal disturbances, and neural system dysfunction. It is basically classified into three major clinical phenotypes: allergic rhinitis (AR), infectious rhinitis, and non-allergic, non-infectious rhinitis (NAR). However, this subdivision may be considered as an oversimplification because a combined (mixed) phenotype exists in many individuals and different endotypes of rhinitis subgroups are overlapping. Due to the variety of pathophysiologic mechanisms (endotypes) and clinical symptoms (phenotypes), it is difficult to develop clear guidelines for diagnosis and treatment. This study aims to review the types of allergic and non-allergic rhinitis, providing a thorough analysis of the pathophysiological background, diagnostic approach, and main treatment options.

Multidisciplinary Care for Severe or Uncontrolled Chronic Upper Airway Diseases.

PURPOSE OF REVIEW: A multidisciplinary approach is regarded as the best practice for many chronic diseases, such as cancer and asthma, with well-documented value. There is also evidence that it may be beneficial to patients with chronic rhinosinusitis (CRS) and/or allergic airway disease presenting to tertiary referral centres. We discuss here whether and how organizing this kind of healthcare transition into a more integrated care pathway would benefit severe chronic upper airways disease (SCUAD) management. RECENT FINDINGS: Based on a recent related EUFOREA panel discussion, literature search, and review of the best overseas practices, an appropriate implementation strategy of multidisciplinary care and its potential results are presented. Organizational principles, hurdles, and challenges of the process, as well as envisaged solutions and results, are being reported. The efficiency of care and the quality control assessment are concepts that are currently gaining importance. At the same time, novel treatment options based on molecular and precision medicine advancements, such as biologics, are being increasingly prescribed. Appropriately organized multidisciplinary care teams can adapt to new demands, data, and discoveries to assure maximum benefit for both patients and healthcare professionals.

Imaging in chronic rhinosinusitis: A systematic review of MRI and CT diagnostic accuracy and reliability in severity staging.

BACKGROUND: Computerized tomography (CT) severity scores are frequently used as an objective staging tool in chronic rhinosinusitis (CRS). Magnetic resonance imaging (MRI) has also been proposed as a valid option in CRS imaging. PURPOSE: The aim of this systematic review was to briefly present the recent developments on sinus imaging utilized in clinical practice with regard to diagnostic accuracy of imaging and severity staging in CRS according to evidence-based medicine (EBM) principles. MATERIAL AND METHODS: This review paper has been assembled following PRISMA guidelines. A PubMed and Scopus (EMBASE) search using CRS, "severity staging", "diagnostic accuracy "and "imaging "resulted with 80 results. Of these, only 12 (59%) contained original data, constituting the synthesis of best-quality available evidence. RESULTS: CT is the most commonly used imaging technique for the severity staging of CRS, but a question of higher cumulative radiation dose should be taken into consideration when repeating CT examinations in evaluating treatment efficacy. MRI may be a complementary diagnostic and staging tool, especially when repeated examinations are required, or when paediatric CRS patients are evaluated. The severity staging system may be improved to better correlate with subjective scores. CONCLUSIONS: MRI may be utilized as a staging tool with comparable diagnostic accuracy, using the same staging systems as with CT examinations.

New concepts in pediatric rhinitis.

Rhinitis-and especially allergic rhinitis (AR)-remains the most frequent hypersensitivity condition, affecting up to a quarter of the population and impacting the quality of life of individual patients and the health economy. Data, especially with respect to underlying pathophysiologic mechanisms, mainly derive from studies on adults and are subsequently extrapolated to the pediatric population. Therapeutic algorithms for children with rhinitis are long based on the same principles as in adults. We explore and describe novel aspects of rhinitis, ranging from mechanisms to disease classification, phenotypes, diagnostic and monitoring tools, and the use of treatments, with a focus on the traits of pediatric age groups.

Surgery in Nasal Polyp Patients: Outcome After a Minimum Observation of 10 Years.

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) often requires surgery, but recurrence even after surgery is common. Recurrence rates largely vary in literature and asthma seems to be a comorbid factor. OBJECTIVE: In this study, we aim to estimate disease recurrence during a long-term follow-up, together with the investigation of possible predicting and/or influencing parameters. METHODS: Out of 196 patients operated for CRSwNP between 01/2000 and 01/2006, 133 patients had a follow-up of at least 10 years and could be included. The inflammatory profile at surgery was determined on nasal tissue and sinonasal secretions, and included analysis of eosinophils, eosinophilic-rich mucus (ERM) typically containing Charcot-Leyden crystals (CLC), and fungal hyphae (FH). During follow-up, recurrence, received treatments and comorbidities were collected. RESULTS: Out of the 133 included patients, local eosinophilia was present in 81% and ERM in 60%. Recurrence during follow-up was observed in 62%, and was associated with local eosinophilia and ERM (both p < 0.001). Asthma was present in 28% at inclusion, and 17% developed asthma after surgery during follow-up. The presence of asthma, at inclusion as well as developed during follow-up, was significantly associated with recurrence of CRSwNP (p = 0.001 for group comparison). CONCLUSION: Recurrence after CRSwNP surgery is common when a long-term follow-up is taken into account. ERM detected in sinonasal secretions at surgery seems to be a predictive factor for recurrence and need for revision surgery. Asthma is a frequently found comorbid factor in CRSwNP, develops even at higher age despite surgical treatment for CRSwNP, and is also associated with a higher recurrence rate. Sustained medical care after surgery is mandatory.

Real-life assessment of chronic rhinosinusitis patients using mobile technology: The mySinusitisCoach project by EUFOREA.

BACKGROUND: Chronic rhinosinusitis (CRS) is a chronic inflammatory disease associated with a substantial personal and socioeconomic burden. Monitoring of patient-reported outcomes by mobile technology offers the possibility to better understand real-life burden of CRS. METHODS: This study reports on the cross-sectional evaluation of data of 626 users of mySinusitisCoach (mSC), a mobile application for CRS patients. Patient characteristics of mSC users were analysed as well as the level of disease control based on VAS global rhinosinusitis symptom score and adapted EPOS criteria. RESULTS: The mSC cohort represents a heterogeneous group of CRS patients with a diverse pattern of major symptoms. Approximately half of patients reported nasal polyps. 47.3% of all CRS patients were uncontrolled based on evaluation of VAS global rhinosinusitis symptom score compared to 40.9% based on adapted EPOS criteria. The impact of CRS on sleep quality and daily life activities was significantly higher in uncontrolled versus well-controlled patients. Half of patients had a history of FESS (functional endoscopic sinus surgery) and reported lower symptom severity compared to patients without a history of FESS, except for patients with a history of more than 3 procedures. Patients with a history of FESS reported higher VAS levels for impaired smell. CONCLUSION: Real-life data confirm the high disease burden in uncontrolled CRS patients, clearly impacting quality of life. Sinus surgery improves patient-reported outcomes, but not in patients with a history of more than 3 procedures. Mobile technology opens a new era of real-life monitoring, supporting the evolution of care towards precision medicine.

Local Allergic Rhinitis Revisited.

PURPOSE OF REVIEW: Local allergic rhinitis (LAR) represents a diagnostic and therapeutic challenge for clinicians. Even though it affects a considerable number of chronic rhinitis patients and a significant number of articles regarding prevalence, evolution, diagnosis, and treatment have been published, the condition remains still largely unrecognized and therefore misdiagnosed and mistreated. RECENT FINDINGS: LAR is a unique form of chronic rhinitis; it is neither classical allergic rhinitis (AR) nor non-allergic rhinitis (NAR). The symptoms, duration, severity, and complications of LAR are similar to those of AR and can affect adults and children. Thus, a portion of patients diagnosed with NAR or chronic rhinitis of unknown etiology may have LAR. The relationship between LAR inflammation and systemic allergic inflammation is unclear. Patients are frequently misdiagnosed with idiopathic NAR, and distinguishing between both entities is difficult without specific diagnostic tests. Underdiagnosis of LAR has implications on the management of these patients, as they are deprived of allergen immunotherapy (AIT) that has been demonstrated to modulate the immune mechanisms underlying allergic diseases. This review aims to comprehensively summarize the current knowledge on LAR and address unmet needs in the areas of disease diagnosis and treatment.

Management of a Buccal Space Mass: A Clinical Case Report.

BACKGROUND: Buccal space tumors constitute rare pathologies with significant histological diversity. They may pose serious diagnostic and therapeutic challenges for the head and neck surgeon. METHODS: A case of buccal space tumor diagnosed and treated in a tertiary center is presented. Clinical presentation, imaging, and surgical approach are discussed, followed by review of the literature. RESULTS: A 79-year-old male patient with a slowly growing painless mass on the right cheek presented to a head and neck reference center. Imaging revealed a tumor of the right buccal space with nonspecific characteristics. Imaging studies revealed extended infiltration of the masseter muscle as well as the anterior border of the parotid gland. FNA biopsy was performed but was nondiagnostic. The decision of surgical excision with a modified parotidectomy incision was taken. The lesion was completely excised with preservation of neighboring facial nerve branches and ipsilateral Stensen's duct. The postoperative course was uneventful. Histological examination showed CLL/Lymphoma, and the patient was referred to the hematology department for staging and further management. CONCLUSION: Differential diagnosis of buccal space masses is very diverse. Despite challenges in the diagnostic and therapeutic approach, these entities may be managed surgically with minimal morbidity.

Sublingual Immunotherapy Attenuates Nasal Symptoms Upon Allergen Exposure in Murine Allergic Rhinitis Model via an Induction of IL-10 producing T cells in Submandibular Lymph Node.

OBJECTIVE: Sublingual immunotherapy has been considered to be a painless and effective therapeutic treatment of patients with allergic rhinitis. Its mechanism of action has been elucidated, but there are still controversies among many reports between clinical efficacy and laboratory data. Therefore, its mechanism of action needs to be investigated further by using promising animal models such as rodents and monkeys. MATERIALS AND METHODS: Bearing this in mind, in our present study, we successfully constructed an effective murine model for sublingual immunotherapy (SLIT) in allergic rhinitis in which mice were sublingually administered ovalbumin (OVA), followed by intraperitoneal (ip) sensitization and intranasal (i.n.) challenge of OVA. RESULTS: To summarize our experimental data, nasal symptoms such as sneezing and nasal rubbing of sublingually treated mice were significantly attenuated in accordance with lower specific IgE antibodies in sera. Histological analysis of eosinophil recruitment in nasal mucosae reveals less allergic inflammation in sublingually treated mice. Interleukin-10 (IL-10) production and IL-10-specific mRNA gene expression of cultured submandibular lymph node (SMLN) cells with OVA, obtained from sublingually treated mice, were significantly higher than those of mice without sublingual treatment. CONCLUSION: These results demonstrate that sublingually introduced antigens can actually attenuate nasal symptoms in a murine allergic rhinitis model upon allergen exposures. Furthermore, our immunological data might indicate an important role of IL-10 producing T cells in SMLN to control nasal allergic reaction.

Clinical Applications for Tissue Engineering in Rhinology.

Tissue engineering implies a number of established techniques in several fields in medicine. A thorough review of current clinical applications for tissue engineering in rhinology is addressed. Current status, as well as, published in vivo studies is presented. Moreover, relevant clinical applications and future perspectives of tissue engineering are demonstrated. There is a lack of high quality clinical studies in the literature regarding the role of tissue engineering in the rhinology field. Further research is needed to translate this concept from bench to bedside.

Differentiating Rhinitis in the Paediatric Population by Giving Focus on Medical History and Clinical Examination.

Chronic rhinitis is defined as an inflammation of the nasal epithelium, and is characterized by the presence of two or more specific nasal symptoms including obstruction, rhinorrhea, sneezing, and/or itching for at least 12 weeks. In childhood, this clinical entity is very common and carries a significant socioeconomic burden. The impact on the physical, social, and psychological well-being of family cannot be underestimated. Rhinitis is an umbrella term which includes different phenotypes of rhinitis with distinct underlying pathophysiologic mechanisms. In most cases the diagnosis of rhinitis is rather straightforward; however, sometimes when based on clinical symptomatology, characterization may be challenging. Herein, we provide guidance for getting all the data needed for the differential diagnosis of rhinitis based on medical history and clinical examination.
