RESUMO

BACKGROUND: Nonsteroidal anti-inflammatory drug-exacerbated respiratory disease (N-ERD) is often characterized by a severe course of chronic rhinosinusitis with nasal polyps (CRSwNP), comorbid asthma, and NSAID hypersensitivity. The gold standard for N-ERD diagnosis is challenge with acetylsalicylic acid (ASA). In expert recommendations, the diagnosis of N-ERD is established based on a plausible positive history of NSAID hypersensitivity and CRSwNP with asthma. OBJECTIVE: The following review describes the performance of ASA challenges and their sensitivity and specificity. It also examines the extent to which a positive history of NSAID hypersensitivity correlates with ASA challenge results in clinical trials and when ASA challenges should be performed. RESULTS AND CONCLUSION: ASA challenges have high sensitivity and specificity. In clinical ASA challenge studies, there is a high concordance between a positive history of NSAID hypersensitivity obtained by rhinologists and the measured data of ASA challenge in patients with CRSwNP and comorbid asthma. Therefore, ASA challenge is primarily indicated in patients with an unclear history of NSAID hypersensitivity.

RESUMO

OBJECTIVE: Drug-induced sleep endoscopy (DISE) is an established diagnostic procedure to assess the upper airway in patients with obstructive sleep apnea. During DISE airway opening is regularly simulated by various maneuvers. One of them is mandibular advancement by the modified jaw-thrust maneuver (MJTM). MATERIAL AND METHODS: All DISE examinations evaluated by VOTE classification in the last 15 months were included. The effect of MJTM on anatomical levels was analyzed retrospectively. Frequency and type of collapse at the anatomic levels were recorded. Apnea-hypopnea index (AHI), body mass index (BMI), Epworth Sleepiness Scale (ESS) were determined. RESULTS: 61 patients were included (f=13, m=48, 54.3±12.9 y, ESS 11±5.5, AHI 30.2±19/h, BMI 29.7±4.5 kg/m2). A correlation of r=0.30 was found between AHI and BMI (p=0.02). At velum level, concentric collapse was detected in 16.4%, anterior-posterior (a.p.) collapse in 70.5%, and lateral collapse in 11.5%. A resolution of the collapse using the MJTM was observed in 75.5% of patients. However, in the presence of concentric collapse, opening was evident in 33.3% of cases in contrast to 86.5% in patients with a.p. collapse. Base of tongue collapse was resolved in 98.0% of the cases. CONCLUSION: A correlation between the success of the MJTM on airway opening at the velum level and the pattern of palatal collapse was found. In therapies aimed at mandibular advancement, e.g. hypoglossal nerve stimulation, an effect on velopalatal airway opening has relevance, so optimization of preoperative diagnosis is of particular importance.

RESUMO

Permanent hearing loss is one of cisplatin's adverse effects, affecting 30-60% of cancer patients treated with that drug. Our research group recently identified resident mast cells in rodents' cochleae and observed that the number of mast cells changed upon adding cisplatin to cochlear explants. Here, we followed that observation and found that the murine cochlear mast cells degranulate in response to cisplatin and that the mast cell stabilizer cromoglicic acid (cromolyn) inhibits this process. Additionally, cromolyn significantly prevented cisplatin-induced loss of auditory hair cells and spiral ganglion neurons. Our study provides the first evidence for the possible mast cell participation in cisplatin-induced damage to the inner ear.

RESUMO

The lifetime prevalence of urticaria, a severe allergic disease, is almost 20%. It not only limits the quality of life of those affected, but also their general performance at work and in their daily activities. This publication is the first section of the Urticaria Guideline. It covers the classification and diagnosis of urticaria, taking into account the major advances in research into its causes, triggering factors and pathomechanisms. It also addresses strategies for the efficient diagnosis of the different subtypes of urticaria. This is crucial for individual, patient-oriented treatment, which is covered in the second part of the guideline, published separately. This German-language guideline was developed according to the criteria of the AWMF on the basis of the international English-language S3 guideline with special consideration of health system characteristics in the German-speaking countries. This first part of the guideline describes the classification of urticaria, distinguishing spontaneously occurring wheals (hives) and angioedema from forms of urticaria with inducible symptoms. Urticaria is defined as sudden onset of wheals, angioedema, or both, but is to be distinguished from conditions in which wheals occur as a short-term symptom, such as anaphylaxis. The diagnosis is based on (a limited number of) laboratory tests, but especially on medical history. In addition, validated instruments are available to measure the severity, activity and course of the disease.

RESUMO

This publication is the second part of the German-language S3 guideline on urticaria. It covers the management of urticaria and should be used together with Part 1 of the guideline on classification and diagnosis. This publication was prepared according to the criteria of the AWMF on the basis of the international English-language S3 guideline with special consideration of health system conditions in German-speaking countries. Chronic urticaria has a high impact on the quality of life and daily activities of patients. Therefore, if causal factors cannot be eliminated, effective symptomatic treatment is necessary. The recommended first-line treatment is to administer new generation, non-sedating H1 antihistamines. If the standard dose is not sufficiently effective, the dose should be increased up to fourfold. For patients who do not respond to this treatment, the second-line treatment in addition to antihistamines in the treatment algorithm is omalizumab and, if this treatment fails, ciclosporin. Other low-evidence therapeutic agents should only be used if all treatments in the treatment algorithm agreed upon by the guideline group fail. Both the benefit-risk profile and cost should be considered. Corticosteroids are not recommended for long-term treatment due to their inevitable severe side effects.

RESUMO

Cochlear implant (CI) treatment is now established as a successful standard of care for auditory rehabilitation of profoundly deaf or severe hearing loss patients. CI candidates with tinnitus also benefit from improved health-related quality of life (HRQoL) and tinnitus burden. Current CI indications include bilateral (double-sided) profound hearing loss and deafness (DSD), unilateral (single-sided) deafness (SSD), and asymmetric hearing loss (AHL). The new and expanded indications for cochlear implants result in different healthcare situations, which may also be associated with differences in tinnitus burden before and after CI treatment. In this article, we discuss the prevalence of tinnitus in different patient groups and the influence of CI on tinnitus prevalence and severity in these groups. In addition, further therapeutic options for tinnitus suppression based on the CI principle are presented, including the development of an anti-tinnitus implant (proof of concept).

RESUMO

Human papillomaviruses (HPV) 6 and 11 cause 90% of recurrent laryngeal papillomatosis (RLP). It is unclear whether recurrences are caused by new infections or the spread of infected cells. Symptomatic and sometimes curative treatment is laser surgery or conventional microsurgical removal. RLP surgery aims to relieve shortness of breath and improve the voice. Patients (especially children) are affected by voice problems, repetitive surgeries, pulmonary manifestations, and psychological trauma. Vaccination with Gardasil 9 (Merck & Co., Rahway, NJ, USA) prevents new infections with HPV 6, 11, 16, 18, 31, 33, 45, 52, and 58 and induces vaccine antigen-specific antibodies and CD4+ T helper cells. According to current studies, RLP can be avoided with prophylactic vaccination. The treatment is associated with a general vaccination risk (European Medicines Agency approval: girls and boys from 9 years). Studies also show that the vaccine after removal of HPV-associated neoplasia/papilloma prevents recurrences. Extension of the vaccination recommendation to prevent recurrences of HPV-associated diseases in men may promote applicability and herd immunity. For rare and treatment-refractory cases with laryngotracheal involvement, systemic therapy with bevacizumab (e.g. Avastin; Genentech, San Francisco, CA, USA), a VEGF antibody, is a promising adjuvant treatment option.

RESUMO

BACKGROUND: Patients with single-sided deafness (SSD) and asymmetric hearing loss (AHL) are increasingly being treated with cochlear implants (CI) due to the demonstrated improvements in auditory abilities and quality of life. To date, there are few published studies in which these two groups are comparatively studied. The aim of the current study was to examine which factors differ between those two patient groups, especially preoperatively. METHODS: A secondary analysis of the previously published raw data of 66 prospectively recruited CI patients (21 SSD/45 AHL) was performed. In addition to the hearing outcome, tinnitus distress (tinnitus questionnaire), health-related quality of life (Nijmegen Cochlear Implant Questionnaire, NCIQ), stress (Perceived Stress Questionnaire, PSQ), and psychological comorbidities (General Depression Scale, ADS­L and Generalized Anxiety Disorder scale, GAD-7) were assessed in SSD and AHL patients pre- and postoperatively. RESULTS: Preoperatively, SSD patients showed significantly higher scores in the NCIQ subdomains "elementary" and "advanced sound perception" than the AHL group. Stress (PSQ) and anxiety symptoms (GAD-7) were significantly higher preoperatively in SSD patients than in AHL patients. After CI, these differences were strongly reduced, with minimal differences being detectable between the groups in the investigated domains postoperatively. CONCLUSION: SSD and AHL patients differ significantly preoperatively in terms of their subjective hearing assessment and psychosocial parameters. In SSD patients, psychological stress factors may have a stronger impact on the quality of life than in AHL patients. These aspects should be taken into account in the preoperative counseling and postoperative rehabilitation.

RESUMO

BACKGROUND: The upper respiratory tract (URT) is the primary entry site for severe acute respiratory syndrome 2 (SARS-CoV-2) and other respiratory viruses, but its involvement in viral amplification and pathogenesis remains incompletely understood. METHODS: In this study, we investigated primary nasal epithelial cultures, as well as vital explanted tissues, to scrutinize the tropism of wild-type SARS-CoV-2 and the recently emerged B.1.1.7 variant. RESULTS: Our analyses revealed a widespread replication competence of SARS-CoV-2 in polarized nasal epithelium as well as in the examined URT and salivary gland tissues, which was also shared by the B.1.1.7 virus. CONCLUSIONS: In our analyses, we highlighted the active role of these anatomic sites in coronavirus disease 2019.

RESUMO

PURPOSE: Since 2001, hypoglossal nerve stimulators have been implanted in patients with obstructive sleep apnea around the world, initially in trial situations but more recently also in regular care settings. Medium term data indicate effectiveness and tolerability of treatment. However, when assessing the safety of the procedure, the safe feasibility of explantation or reimplantation must also be considered. PATIENTS AND METHODS: Nine patients with an implanted respiratory-driven hypoglossal nerve stimulator. We have evaluated the feasibility and safety of explantation or re-implantation with another stimulation system. RESULTS: In 2012, nine patients were implanted with a respiratory-driven hypoglossal nerve stimulator as part of the Apnex Medical Pivotal Study. The study was ended in 2013. For a variety of reasons, the system was explanted from all nine patients by the year 2019. Three of these patients were re-implanted with a different system with respiratory sensing during the same session (mean incision to closure time for explantation 88.2 ± 35.01 min., mean incision to closure time for re-implantation 221.75 ± 52.73 min.). Due to extensive scar tissue formation, all procedures were technically challenging. Complication rate was significantly higher when re-implantation was performed or attempted in the same surgical session (0 of 5 patients with explantation versus 3 of 4 patients with attempted re-implantation; p = 0.018). There was no significant difference between the AHI values before and after implantation in patients with re-implantation. CONCLUSION: Explantation and re-implantation are technically challenging though possible procedures. The single-staged equilateral reimplantation of another hypoglossal nerve stimulation system can, but need not, be successful.

RESUMO

PURPOSE: Bilateral cochlear implant (CI) implantation is increasingly used in the auditory rehabilitation of bilaterally deafened adults. However, after successful unilateral implantation, objective patient counselling is essential. METHODS: We investigated the extra benefit of a second CI in adults in terms of health-related quality of life, tinnitus, stress, anxiety, depression, quality of hearing, and speech recognition. Hearing ability was assessed by using the Freiburg monosyllable speech discrimination test (FB MS) and the Oldenburg sentence test with azimuth variations. In a prospective patient cohort, we administered validated questionnaires before a CI, after a first CI and after a second CI implantation. RESULTS: The study included 29 patients, made up of nine women and 20 men. The median time between the first and the second implantation was 23 months. The mean total NCIQ score and TQ before a CI improved significantly after both implantations. Stress, anxiety, and depression were stable over time and were not significantly affected by CI implantations. Speech recognition with noise significantly improved after the first and again after the second CI. Correlation analysis showed a strong connection between auditory performance and HRQoL. CONCLUSION: We demonstrated that a unilateral CI benefitted many fields and that the second sequential CI leads again to additional improvement. Bilateral CI implantation should, therefore, be the standard form of auditory rehabilitation in deafened adults.

RESUMO

PURPOSE: The aim was to analyze the incidence and survival of patients living with HIV (PLWH) with head and neck squamous cell carcinoma (HNSCC) and to compare with a control group of HIV-negative HNSCC patients. METHODS: Clinicopathological data and predictors for overall survival (OS) and disease-free survival (DFS) were investigated (2009-2019). RESULTS: 50 of 5151 HNSCC patients (0.97%) were PLWH, and 76% were smokers. Age ≤ 60 years, HIV-PCR ≤ 50 copies, CD4 cells ≤ 200/mm3, cART treatment, T and UICC classification, oral cavity and nasal/paranasal sinuses, and therapy were significantly associated with OS in univariate analysis. In the multivariate analysis, only age and HIV-PCR independently predicted OS. The OS of the 50 PLWH was not significantly altered compared with the 5101 HIV-negative controls. However, OS and DFS were significantly inferior in advanced tumor stages of PLWH compared with an age-matched control group of 150 HIV-negative patients. CONCLUSIONS: PLWH were diagnosed with HNSCC at a significantly younger age compared to HIV-negative patients. Taking into account patient age at initial diagnosis, both OS and DFS rates in PLWH are significantly worse compared with a matched control group of HIV-negative patients in advanced tumor stages UICC III/IV. The prognosis (OS) is improved when taking cART treatment, the HIV viral load is undetectable and CD4 count is high.

RESUMO

BACKGROUND: Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) generally have a high symptom burden and poor health-related quality of life, often requiring recurring systemic corticosteroid use and repeated sinus surgery. Dupilumab is a fully human monoclonal antibody that inhibits signalling of interleukin (IL)-4 and IL-13, key drivers of type 2 inflammation, and has been approved for use in atopic dermatitis and asthma. In these two studies, we aimed to assess efficacy and safety of dupilumab in patients with CRSwNP despite previous treatment with systemic corticosteroids, surgery, or both. METHODS: LIBERTY NP SINUS-24 and LIBERTY NP SINUS-52 were two multinational, multicentre, randomised, double-blind, placebo-controlled, parallel-group studies assessing dupilumab added to standard of care in adults with severe CRSwNP. SINUS-24 was done in 67 centres in 13 countries, and SINUS-52 was done in 117 centres in 14 countries. Eligible patients were 18 years or older with bilateral CRSwNP and symptoms despite intranasal corticosteroid use, receiving systemic corticosteroids in the preceding 2 years, or having had sinonasal surgery. Patients in SINUS-24 were randomly assigned (1:1) to subcutaneous dupilumab 300 mg or placebo every 2 weeks for 24 weeks. Patients in SINUS-52 were randomly assigned (1:1:1) to dupilumab 300 mg every 2 weeks for 52 weeks, dupilumab every 2 weeks for 24 weeks and then every 4 weeks for the remaining 28 weeks, or placebo every 2 weeks for 52 weeks. All patients were randomly assigned centrally with a permuted block randomisation schedule. Randomisation was stratified by asthma or non-steroidal anti-inflammatory drug-exacerbated respiratory disease status at screening, previous surgery at screening, and country. Patients with or without comorbid asthma were included. Coprimary endpoints were changes from baseline to week 24 in nasal polyp score (NPS), nasal congestion or obstruction, and sinus Lund-Mackay CT scores (a coprimary endpoint in Japan), done in an intention-to-treat population. Safety was assessed in a pooled population of both dupilumab groups in SINUS-52 up to week 24 and the dupilumab group in SINUS-24 and the placebo groups in both studies until week 24. The trials are complete and registered at ClinicalTrials.gov, NCT02912468 and NCT02898454. FINDINGS: Between Dec 5, 2016, and Aug 3, 2017, 276 patients were enrolled in SINUS-24, with 143 in the dupilumab group and 133 in the placebo group receiving at least one study drug dose. Between Nov 28, 2016, and Aug 28, 2017, 448 patients were enrolled in SINUS-52, with 150 receiving at least one dose of dupilumab every 2 weeks, 145 receiving at least one dose of dupilumab every 2 weeks for 24 weeks and every 4 weeks until week 52, and 153 receiving at least one dose of placebo. Dupilumab significantly improved the coprimary endpoints in both studies. At 24 weeks, least squares mean difference in NPS of dupilumab treatment versus placebo was -2·06 (95% CI -2·43 to -1·69; p<0·0001) in SINUS-24 and -1·80 (-2·10 to -1·51; p<0·0001) in SINUS-52; difference in nasal congestion or obstruction score was -0·89 (-1·07 to -0·71; p<0·0001) in SINUS-24 and -0·87 (-1·03 to -0·71; p<0·0001) in SINUS-52; and difference in Lund-Mackay CT scores was -7·44 (-8·35 to -6·53; p<0·0001) in SINUS-24 and -5·13 (-5·80 to -4·46; p<0·0001) in SINUS-52. The most common adverse events (nasopharyngitis, worsening of nasal polyps and asthma, headache, epistaxis, and injection-site erythema) were more frequent with placebo. INTERPRETATION: In adult patients with severe CRSwNP, dupilumab reduced polyp size, sinus opacification, and severity of symptoms and was well tolerated. These results support the benefits of adding dupilumab to daily standard of care for patients with severe CRSwNP who otherwise have few therapeutic options.

RESUMO

PURPOSE: The non-invasive diagnosis of acute rhinosinusitis (ARS) remains an unresolved problem of modern otolaryngology. Analog diaphanoscopy of reduced transillumination (shading) could be enhanced by a digital image processing of the maxillary sinuses. By this means, the limited ergonomics of this safe and low-cost method can be overcome, and merits renewed the investigation. Here, we compared the diagnostic sensitivity and specificity of digital diaphanoscopy and computed tomography (CT) in detecting shading in the maxillary sinus. MATERIALS AND METHODS: We examined 103 adults using both digital diaphanoscopy of the maxillary sinus and native-phase cranial CT. We developed a scoring system for investigation of shading in the maxillary sinus using diaphanoscopy and compared the sensitivity and specificity with that of CT. Also, we documented a follow-up of acute rhinosinusitis. RESULTS: In diagnosing shading in the maxillary sinus, digital diaphanoscopy had a sensitivity of 86% and a specificity of 88%. Digital diaphanoscopy can be used not only in the screening of ARS but also for documentation of its course. CONCLUSION: This study supports the role of modern digital diaphanoscopy in the diagnosis of shading in the maxillary sinus, especially in patients with ARS when CT imaging is not recommended. The ergonomics of analog diaphanoscopy could be significantly improved for physicians and patients by the implementation of modern hardware and software components. Further development of the technique and the use of several discrete wavelengths will improve this method's sensitivity and specificity.

RESUMO

The last years' developments could show that the rehabilitation with hearing implants is a field with the highest potential for development and innovation in otorhinolaryngology. New or extended indications were seen with developments of implants, new surgical techniques, and respective rehabilitation strategies.With the background of limited resources, the increasing number of subjects suffering from hearing disorders, the extended indications and thus the increasing number of CI carriers as well as the need of life-long CI follow-up are one of the major challenges of the future. In order to cope with this situation, completely new strategies are required beside a close interdisciplinary cooperation and continuous development of the therapy. In this context, digitization of all these processes plays a key role.This manuscript will describe and discuss the current developments from the perspective of a cochlea implant (CI) providing hospital. The contribution will elucidate manifold digital applications that may be implemented in all phases of CI provision, starting with patient information about the possibilities of hearing screening and preoperative evaluation up to life-long follow-up and clinical research.The focus is mainly placed on specific applications that play a particular role in the development of digital progresses and structures in the context of cochlea implantation and that are crucial for understanding the further development.The options of simplified fitting result for example from automated MAP creation (artificial intelligence); remote care networks (telemedicine, apps) foster the active contribution of the patients themselves and allow completely new types of location-independent healthcare (automated technical implant control, individual settings, upgrades). Central databases may create backups of the current MAP (for example in cases of repair), and document technical data and the hearing performance. Some applications described here, are already implemented in the routine, others are currently being developed.Understanding the possibilities of digitization and their implementation in the context of hearing rehabilitation with hearing implants as well as the recognition of the enormous potential for effective, time-efficient structures is essential in order to use this potential. We as ENT specialists are important protagonists in the healthcare system and beside our high specific expertise we have to meet the requirements of our qualification with regard to digital applications so that we might actively contribute to the success of this process.

RESUMO

Although the association between odor concentration and olfactory event-related potential (OERP) has been studied, less is known about the influence of airflow on OERP. The aim of this study was to investigate the influence of airflow rate and stimulus concentration on OERP in humans. Electroencephalogram data were collected from young healthy volunteers (n = 17) in separate sessions where 2-phenylethanol (PEA) was delivered in the following conditions: 8 L/min 50% v/v, 8 L/min 30% v/v, 4 L/min 100% v/v, and 4 L/min 60%v/v. Odor concentrations are referred to the %v/v achieved with air dilution and was not measured in the nose. Odor intensity ratings were recorded immediately after stimulus presentation. Data recorded at 5 electrodes (Fz, Cz, Pz, C3, and C4) were pooled and analyzed using both time-domain averaging and single-trial time-frequency domain approaches. Higher airflow rate significantly increased intensity ratings (F = 10.98, P < 0.01), and improved the signal-to-noise-ratio (F = 5.42, P = 0.025). Results from time-frequency analysis showed higher concentration versus lower concentration increased brain oscillations in the slow frequency band (1-3 Hz) at 0-600 ms; while higher airflow rates versus lower airflow rate increased theta-band oscillations (300-600 ms and 5-9 Hz) and decreased delta-band oscillations at 900-1500 ms after stimulus onset. In conclusion, compared to stimulus concentration, airflow rate was associated with improved OERP quality and more pronounced responses. The results suggest that intensity ratings and OERP are strongly related to the steepness of stimulus onset. High airflow rates are suggested for odor delivery in order to record OERP.

RESUMO

OBJECTIVES: We determined the audiological outcome, the subjective and objective hearing quality in patients suffering from asymmetric hearing loss (AHL). Furthermore, we evaluated psychological comorbidities and tinnitus burden before and after cochlear implantation. STUDY DESIGN: Prospective cohort study. METHODS: 44 AHL patients were unilaterally implanted with a multichannel cochlear implant between 2011 and 2016. Speech discrimination (Freiburg Monosyllable Word Test, Oldenburg Sentence Test) was measured before, 6 and 12 months after implantation. Subjective hearing quality, health-related quality of life (HRQoL), tinnitus burden, anxiety, depressiveness, perceived stress level and coping abilities were evaluated before implantation, 6 and 12 months postoperative using specific validated questionnaires (Oldenburg Inventory, Nijmegen Cochlear Implantation Questionnaire, Tinnitus Questionnaire, General Anxiety Disorder-7, Depression Scale, Perceived Stress Questionnaire and Cope Inventory). RESULTS: Subjective and objective hearing quality, speech discrimination and health-related quality of life were significantly increased in AHL patients. Tinnitus burden significantly decreased over the 12 postoperative months. No significant alteration was observed for anxiety, depressiveness, coping abilities and stress level. CONCLUSIONS: This study demonstrates that cochlear implantation achieves hearing rehabilitation, increases HRQoL and decreases tinnitus burden in patients suffering from AHL. Subjective hearing quality increased, while tinnitus burden significantly decreased 6 and 12 months after implantation. HRQoL in AHL patients is an important factor to focus on and is significantly increased postoperatively. In contrast, general anxiety, depressiveness, coping abilities and perceived stress level remained unaffected.
