Accuracy of the Bedside Examination in Patients With Suspected Acute Unilateral Peripheral Vestibulopathy.

OBJECTIVE: Acute unilateral peripheral vestibulopathy (AUPVP) is a frequent form of peripheral vestibular vertigo characterized by unilateral vestibular organ dysfunction. Diagnostic challenges in anamnesis and bedside examination can lead to potential misdiagnoses. This study investigated the sensitivity of bedside examinations in diagnosing AUPVP. METHODS: This retrospective analysis examined 136 AUPVP inpatients at a level 3 university hospital between 2017 and 2019. Demographic data and bedside test results were collected. Instrumental otoneurological tests included caloric testing and video head impulse test (HIT). The sensitivity of each bedside parameter was computed based on the instrumental diagnostics, and statistical analyses were performed. RESULTS: The study included 76 men and 60 women, with a mean age of 59.2 years. Spontaneous nystagmus exhibited a sensitivity of 92%, whereas the absence of skew deviation was identified with a sensitivity of 98%. Abnormal bedside HIT showed a sensitivity of 87%. The combined HINTS (HIT, nystagmus, and test of skew) had a sensitivity of 83%. The Romberg test and Fukuda test demonstrated sensitivities of 26% and 48%, respectively. CONCLUSION: The sensitivity of bedside tests varied from 26% to 98%. This aligns with previous literature, highlighting the challenge of differentiating AUPVP from vestibular pseudoneuritis solely through bedside examination. Although the tests excel in excluding central causes, they are insufficient for diagnosing AUPVP with certainty. In addition, the bedside examination sensitivities vary widely, and early radiological imaging can be misleading. Therefore, this study underlines the necessity of prompt otoneurological testing for accurate exclusion of vestibular pseudoneuritis and thus improve patient outcomes.

Analysis of acute COVID-19 including chronic morbidity: protocol for the deep phenotyping National Pandemic Cohort Network in Germany (NAPKON-HAP).

BACKGROUND: The severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) pandemic causes a high burden of acute and long-term morbidity and mortality worldwide despite global efforts in containment, prophylaxis, and therapy. With unprecedented speed, the global scientific community has generated pivotal insights into the pathogen and the host response evoked by the infection. However, deeper characterization of the pathophysiology and pathology remains a high priority to reduce morbidity and mortality of coronavirus disease 2019 (COVID-19). METHODS: NAPKON-HAP is a multi-centered prospective observational study with a long-term follow-up phase of up to 36 months post-SARS-CoV-2 infection. It constitutes a central platform for harmonized data and biospecimen for interdisciplinary characterization of acute SARS-CoV-2 infection and long-term outcomes of diverging disease severities of hospitalized patients. RESULTS: Primary outcome measures include clinical scores and quality of life assessment captured during hospitalization and at outpatient follow-up visits to assess acute and chronic morbidity. Secondary measures include results of biomolecular and immunological investigations and assessment of organ-specific involvement during and post-COVID-19 infection. NAPKON-HAP constitutes a national platform to provide accessibility and usability of the comprehensive data and biospecimen collection to global research. CONCLUSION: NAPKON-HAP establishes a platform with standardized high-resolution data and biospecimen collection of hospitalized COVID-19 patients of different disease severities in Germany. With this study, we will add significant scientific insights and provide high-quality data to aid researchers to investigate COVID-19 pathophysiology, pathology, and chronic morbidity.

Gender distribution and women leadership in German Otolaryngology, Head and Neck Surgery.

Objective: To determine the distribution of female physicians throughout the rank from resident to leadership positions in German Otolaryngology-Head and Neck Surgery (OHNS) departments. Methods: This cross-sectional study collected data about the physician workforce in the German OHNS.The primary outcome was the proportion of female physicians. Data were collected from 165 departments from January 2022 to February 2022. The physician workforce was stratified based on gender and leadership. Results: We included 2089 physicians from 165 departments of OHNS in German hospitals. Female residents and specialists outnumbered male peers (484/872 [55.5%] vs. 388/872 [44.5%] and 224/363 [61.71%] vs. 139/363 [38.29%], respectively). However, the women proportion decreased gradually with elevated hierarchical rank starting at the attending physician level to reaching its lowest extreme (14/165 [7.23%]) at the head of the department level. Holding a leadership position was associated with being male (n = 282 [85.2%] vs. n = 49 [14.8%], p < .0001). This persisted even after controlling the academic rank in a multivariable regression model (OR: 5.027, 95% CI: 3.536-7.146). The gap between the two genders in favor of men regarding leadership persisted in all kinds of hospitals. However, this disparity was lowest in university hospitals, (male: n = 83 [78.3%] vs. female: n = 23, [21.7%], p < .0001). Conclusions: Even though women outnumbered men in resident and specialist positions, they are still underrepresented in leadership positions in OHNS. Continuous surveillance is needed to watch the dynamic changes in the gap between the two genders and address it with more sex equality-supporting policies. Level of Evidence: IV.

[Pyroban on New Year's Eve 2020 & 2021 - Analysis of firework-related injuries over the last 12 years]. / Pyroverbot Silvester 2020 & 2021 ­ Analyse von feuerwerksbedingten Verletzungen der letzten 12 Jahre.

There is an increase of firework-related injuries in Germany at the turn of the year. With regard to hearing, a distinction is made between blast (BT) and explosion trauma (ET). The study examines the prevalence and characteristics of firework-related injuries and the impact of the COVID-19-pandemic pyrotechnic ban on New Year's Eve 2020/21 and 2021/22 compared to the 10-year period prior to the pandemic.A retrospective chart review of all patients who presented themselves with the diagnosis blast trauma (H 83.3) or explosion trauma (T 70.8) at the Charité emergency service in the last 12 years from Dezember 28 to January 5 was performed.276 patients were recorded, 77% of whom were male. 1/3 each were assigned to the age group 10-19 and 20-29 years. 21% of the patients were admitted to the hospital. There was an isolated BT of the ear in 67%, hand injuries in 11%, head injuries in 8% and eye injuries in 4%. 87% had ear involvement with hearing loss; 5% of these with ET.8% of the patients underwent surgical interventions. The treatment of a tympanic membrane perforation was carried out by: 54% splinting, 38% tympanoplasty. Therapy with a glucocorticoid was administered i.v. in 48%. and initiated orally in 20%. Overall, there was a nearly 75% decrease in injuries in 2020 and 2021 compared to the previous 10-year period.The use of fireworks leads to increased utilization of health care resources. The ban on the sale of pyrotechnics as well as the introduction of pyro ban zones in 2020 and 2021 led to a relevant decrease in injuries. 2020 and 2021 were the only years in which there were no injuries in children. The BT of the ear is the most common firework-related injury.

[Demographic and epidemiological risk factors in patients with acute vestibular neuritis]. / Demografische und epidemiologische Risikofaktoren bei Patienten mit akuter unilateraler Vestibulopathie M. Menière (hydropische Innenohrerkrankung).

OBJECTIVE: Vestibular neuritis (VN) is one of the most common peripheral vestibular balance disorder. Demographic and other risk factors associated with VN are insufficiently published. Therefore, the aim of this study is to identify associated risk factors in patients with acute VN. METHODS: This study evaluated all hospitalized VN cases between 2017-2019. Inclusion criteria was an otoneurologically confirmed diagnosis of acute VN. Patient data was compared with data of the German normal population (Robert Koch Institute, "Gesundheit in Deutschland aktuell"). RESULTS: 168 patients (Ø 59.8 years) were included. Compared with the normal German population, the study population was significantly more likely to have preexisting cardiovascular diseases, and the male patients were significantly more likely to have arterial hypertension. No significant differences were measurable between the study population and the normal population for other secondary diseases. Leukocytosis was present in 23% on admission, and 9% of patients reported a history of VZV or HSV-1 disease. DISCUSSION: Etiology and pathogenesis of VN are poorly understood. Inflammatory and vascular causes are discussed. In this study, patients had increased prevalence of cardiovascular disease compared with the normal population, but the study population had a higher average age. Currently, it is unclear what significance nonspecific elevated leukocyte values could have as a possible sign of VN triggered by an infection. Since the number of inpatient cases with VN is rising, prospective studies should be performed to get a better understanding of the pathogenesis of the disease.

Restoring speech intelligibility for hearing aid users with deep learning.

Almost half a billion people world-wide suffer from disabling hearing loss. While hearing aids can partially compensate for this, a large proportion of users struggle to understand speech in situations with background noise. Here, we present a deep learning-based algorithm that selectively suppresses noise while maintaining speech signals. The algorithm restores speech intelligibility for hearing aid users to the level of control subjects with normal hearing. It consists of a deep network that is trained on a large custom database of noisy speech signals and is further optimized by a neural architecture search, using a novel deep learning-based metric for speech intelligibility. The network achieves state-of-the-art denoising on a range of human-graded assessments, generalizes across different noise categories and-in contrast to classic beamforming approaches-operates on a single microphone. The system runs in real time on a laptop, suggesting that large-scale deployment on hearing aid chips could be achieved within a few years. Deep learning-based denoising therefore holds the potential to improve the quality of life of millions of hearing impaired people soon.

Non-intrusive deep learning-based computational speech metrics with high-accuracy across a wide range of acoustic scenes.

Speech with high sound quality and little noise is central to many of our communication tools, including calls, video conferencing and hearing aids. While human ratings provide the best measure of sound quality, they are costly and time-intensive to gather, thus computational metrics are typically used instead. Here we present a non-intrusive, deep learning-based metric that takes only a sound sample as an input and returns ratings in three categories: overall quality, noise, and sound quality. This metric is available via a web API and is composed of a deep neural network ensemble with 5 networks that use either ResNet-26 architectures with STFT inputs or fully-connected networks with wav2vec features as inputs. The networks are trained and tested on over 1 million crowd-sourced human sound ratings across the three categories. Correlations of our metric with human ratings exceed or match other state-of-the-art metrics on 51 out of 56 benchmark scenes, while not requiring clean speech reference samples as opposed to metrics that are performing well on the other 5 scenes. The benchmark scenes represent a wide variety of acoustic environments and a large selection of post-processing methods that include classical methods (e.g. Wiener-filtering) and newer deep-learning methods.

[Dermatomyositis as a paraneoplastic syndrome of head-neck-cancer: Case series & literature review]. / Dermatomyositis als paraneoplastisches Syndrom bei Kopf-Hals-Malignomen: Fallserie & Literaturreview.

INTRODUCTION: Dermatomyositis (DM) is a rare disease with the clinical manifestation of weakness and pain of proximal muscles as well as lilac-coloured skin lesions. One fifth of the cases is associated with the occurrence of a malignant tumor disease. The aim of this study is to evaluate the relevance of DM as a paraneoplastic syndrome in head and neck cancer taken into account the current literature. MATERIAL/METHODS: After retrospective analysis of medical records of head-neck-cancer patients treated between 2008 and 2018, 8 patients with DM were detected: 4 patients with tonsil carcinoma, 1 patient with nasopharyngeal carcinoma, 1 patient carcinoma of the parotid gland and two patients with lymphoma. The diagnosis, therapy and treatment results of these cases are described. Furthermore, a selective analysis of the literature (pubmed) about DM with head-neck cancer was conducted. A total of 290 cases were identified: In 283 cases, the tumors were located in the nasopharynx, in five cases in the tonsil and in two cases in the hypopharynx. CONCLUSION: DM as a paraneoplastic syndrome of head and neck tumors is rare and more often associated with nasopharyngeal cancer and rarely with tonsil cancer. The clustering of DM with head and neck tumors regarding ethnicity (nasopharyngeal carcinoma - Asian origin, tonsillar carcinoma- Caucasian origin) might be due to the regional different incidences of these tumor entities.In patients with DM, especially in presence of cervical lymphadenopathy a tumor in the head and neck area should be evaluated. The course of tumor-associated DM is positively influenced by tumor therapy. The consistent therapy and monitoring of DM is fundamental for a successful tumor treatment as well.

[Vestibular neuritis - prevalence of inpatient cases in Germany]. / Neuropathia vestibularis ­ Prävalenz der stationären Fälle in Deutschland.

INTRODUCTION: The vestibular neuropathy (VN) is a frequently diagnosed, acute peripheral vestibular form of vertigo. Typical symptoms are spinning vertigo, ipsilateral tendency to fall with standing and gait insecurity, and vegetative side effects. Epidemiological studies of VN in the general population are rare and the little existing literature varies in results. MATERIAL AND METHODS: All inpatient VN cases in Germany from 2000 to 2017 were evaluated. The data used was provided by the German Federal Statistical Office. In addition to the annual number of cases, information about age at diagnosis, gender and length of stay were evaluated. RESULTS: Between 2000-2017, 401 242 inpatient cases with VN were reported in Germany. This translates into a prevalence of 36.7 cases/100 000 individuals in 2017. During the examined 17 years the number of cases with VN in Germany increased by approximately 180 %. Across all years evaluated, VN was observed more often among women than among men. The length of stay decreased continuously by a total of 3.3 days during the observation period. DISCUSSION: In 2017, the observed prevalence of VN cases in Germany was 36.7 hospital cases/100 000 individuals. Literature shows a prevalence of non-hospitalized VN cases of 162/100 000 individuals in 2015. Even when taking into account an inaccuracy due to a possible bias, these numbers add up to a much higher prevalence of VN cases than described previously in the literature. The continuous increase in cases with VN in Germany may be associated with demographic changes in age structure and a related higher morbidity.

Mucocutaneous leishmaniasis: case report and literature review of a rare endonasal infection.

Leishmaniasis is a protozoal infection transmitted by a sandfly vector. In Germany, leishmaniasis of the mucous membranes is a rare condition and usually due to extension of local skin disease into the mucosal tissue via direct extension, bloodstream or lymphatics. We report a case of endonasal leishmaniasis in a female German resident who presented in a university hospital with nasal obstruction. Histology of the left nasal septum biopsy was suggestive of leishmaniasis. The molecular detection of DNA was positive for leishmania infantum. The patient was successfully treated as a case of mucocutaneous leishmaniasis receiving liposomal amphotericin follow up visits showed significant improvement with no recurrence.

Rare involvement of paranasal sinuses in sarcoidosis: case report and literature review.

Sarcoidosis is a non-caseating inflammatory chronic systemic disease of unknown etiology, which may affect one or more organs. Paranasal sinuses involvement occurs sporadic in sarcoidosis. We report a patient with a medical history of sarcoidosis involving her lungs, liver, and lymphatic system for four years who now presented with nasal and sinuses symptoms. The primary treatment with local cortisone showed no improvement. Computed tomography (CT) scan of the paranasal sinuses (PNS) revealed signs of chronic pansinusitis. She was successfully treated with endoscopic sinonasal surgery. Subsequent histological analysis confirmed the involvement of the PNS with sarcoidosis. Her follow-up during the last 6 months was without recurrence.

Effective but uncommon treatment of a spontaneous otogenic epidural pneumocephalus.

We describe an uncommon treatment for epidural pneumocephalus and an effective but uncommon treatment option. Complete and permanent relief was achieved in a young patient using a tympanostomy tube to eliminate excessive positive air pressure in the mastoid bone that was the cause of spontaneous pneumocephalus. The patient showed no recurrence and absence of clinical symptoms at outpatient follow-up. Post-traumatic, infectious or spontaneous pneumocephalus may require an active, usually surgical approach. Treatment with a tympanostomy tube can be an alternative in suitable patients.

[Management of thyroid carcinoma arising from thyroglossal duct cyst]. / Vorgehen bei Schilddrüsenkarzinomen in einer medianen Halszyste.

Thyroid carcinoma presenting within thyroglossal duct remnants is rarely reported. Mostly diagnosis is received postoperatively after resection of the cyst. No definite agreement exists regarding the therapeutical management after excision of the cyst especially concerning the necessity of total thyroidectomy and radioiodine therapy. A series of five cases is presented and relevant literature is reviewed.A retrospective review of all patients with thyroglossal duct cyst carcinoma treated between 2002 und 2017 was performed. Out of 578 patients with a thyroglossal duct cyst in five (3 women and 2 men) in the age of 16-73 years (mean: 51, median: 56 years) a thyroidal carcinoma could be identified. All of them presented with a painless hyoidal swelling. Diagnosis was made in all cases after surgery, but in one case, malignancy was presumed in the preoperative MRI. Papillary thyroid carcinoma was found in all samples. Four of the patients underwent total thyroidectomy and radioiodine therapy, in two of them a neck dissection of medial and lateral compartment was performed. The last patient withdrew from further diagnostics and therapy.In all four samples, no carcinoma of the thyroidal gland or nodal metastasis was found. Due to the rare occurrence of thyroidal carcinoma in thyroglossal duct cysts, therapeutical management is controversial.Stratification of patients to risk groups should be used to identify patients, who would benefit from an additional thyroidectomy. Prognosis is excellent.

[Severe Bleeding from the Middle Ear Cavity after Myringotomy: Review Based on a Case Report]. / Massive Blutung bei einer Parazentese: Übersicht anhand eines Fallberichts.

Report of a rare case of severe bleeding from the middle ear cavity after myringotomy. On the basis of the case report, the procedure for such bleeding is discussed in the context of the literature. A 6-year-old boy received a revision myringotomy in an ambulant setting. During the procedure a severe bleeding occurred. The external auditory canal was adequately packed. The patient was extubated and transferred to the clinic as an emergency. Computer tomography of the temporal bone showed the anatomical variant of a dehiscent high jugular bulb, which had been injured. Because no rebleeding occurred, the packing of the ear canal was removed and an explorative tympanoscopy was performed on the third postoperative day. When the tympanomeatal flap was lifted, the defect in the jugular bulb was found. The lesion was covered with Tutopatch® pads and fibrin glue and the auditory canal was packed again. After removal of the packing three weeks postoperatively a properly healed situs was found. No further measures were taken. The injury of a dehiscent jugular bulb in the course of ear surgeries leads to a massive hemorrhage. The case describes the diagnostic and therapeutic procedure for this relatively rare but severe complication.

[The Relevance of Abducent Nerve Palsy in ENT]. / Abduzensparese mit Ursache im HNO-Fachgebiet.

Patients suffering from abducent nerve palsy are usually primary seen by a conservative medical Specialist. In most cases the ENT specialist is secondary involved for treatment. In the majority of cases abducent nerve palsy is a temporary symptom associated with neurologic or vascular diseases. Rarely inflammation, neoplasm or fracture of the skull base cause this symptom and lead to an intervention done by the ENT surgeon. This case series describes retrospectively the abducent palsy seen through the eyes of an ENT surgeon. From 2008 to 2011 15 patients suffering from abducent nerve palsy. One patient suffering from a temporal bone fracture has been treated conservatively while 14 patients needed surgery. 6 patients had a complicated inflammation of the skull base. In 7 patients skull base neoplasms were found in endoscopic surgery. In one case the underlying pathology remained unclear. 2 third of the patients that suffered from complications of inflammatory diseases completely recovered after a combined operative and conservative therapy. The patients who suffered from neoplasms of the skull base partially recovered in only one third, none, achieved full recovery. The patient with the temporal bone fracture achieved a partial recovery after 3 months. If the leading symptom of abducent palsy is caused by a severe extracranial inflammation, neoplasm or trauma an experienced skull base surgeon is mandatory. The recovery rate of abducent palsy in our case series was 60 %. The prognosis of abducent palsy in skull base inflammation is much better compared to patients with skull base neoplasm.

[Tonsillar actinomycosis as a rare cause of oral malodor. Diagnosis beyond a gastroenterologist's nose]. / Tonsilläre Aktinomykose als ungewöhnliche Ursache eines Foetor ex ore. Diagnose jenseits des gastroenterologischen Tellerrandes.

BACKGROUND: Up to 30% of patients seen by dentists suffer from oral malodor. Part of them report serious distress and a sometimes paradoxical discrepancy in subjective and objective perception of symptoms. Less often, patients with oral malodor are primarily seen by general practitioners and specialists like gastroenterologists or ear, nose and throat (ENT) doctors. Correct characterization of the underlying disease and an adequate diagnosis are made most successfully through interdisciplinary cooperation. CASE REPORT: The case of a 43-year-old female patient is reported who presented with persistent oral malodor for > 1 year in the authors' outpatient department. Extensive diagnostic tests performed by various doctors in the past had not led to an adequate diagnosis and treatment. Clinical and laboratory examination in the authors' hospital showed normal findings apart from suspicion of chronic tonsillitis, confirmed by an ENT specialist. Therefore, tonsillectomy was performed. Histopathology revealed chronic tonsillitis with tonsillar actinomycosis but no other disease. 6 months after tonsillectomy the patient presented asymptomatic and comfortable. Oral malodor was no longer detectable. CONCLUSION: Oral malodor has a broad differential diagnosis including chronic tonsillitis caused by Actinomyces species and concomitant anaerobic bacteria able to produce volatile sulphur compounds and other putrefactive molecules. Therapeutic gold standard in symptomatic disease is tonsillectomy, lacking comparative studies on the success rates of conservative antibiotic therapy, e.g., with aminopenicillins plus beta-lactamase inhibitor for several weeks or months. This case presentation illustrates that anticipated internal disease with an agonizing and prolonged cause of disease could be solved by tonsillectomy.

Intralesional Cidofovir application in recurrent laryngeal papillomatosis.

Recurrent laryngeal papillomatosis is a benign disease of the larynx often leading to organic and functional restrictions. The therapeutic treatment of choice in larynx-obstructing papillomatosis is at present surgical laser ablation. The effectiveness of adjuvant intralesional injection of the virustaticum Cidofovir has been investigated recently in a variety of therapeutic models. The present case study deals with the treatment of recurrent laryngeal papillomatosis by means of surgical laser ablation of the laryngeal papillomas with adjuvant local injection of the virustaticum Cidofovir (dose of 5 mg/1 ml). Within the period from October 2001 to August 2004, ten patients aged between 5- and 70 years were treated with intralesional injections of Cidofovir. Papillomatosis was confirmed histologically in all cases, and the virus types were defined in part. Each of the patients underwent clinical-phoniatric examinations and was photographed for documentation. After 2-7 treatments with surgical laser papilloma ablation and intralesional Cidofovir injections, all patients showed a definite papilloma reduction, while in six cases complete remission was achieved. During the follow-up period of 8-30 months, not a single recurrence of the laryngeal papillomatosis occurred. In the majority of patients, a clear improvement in the voice was achieved. There were no local or systemic side effects caused by the virustaticum. Intralesional injection of Cidofovir is an adjuvant, but not a curative therapeutic option in recurrent laryngeal papillomatosis. Remission of previously frequently recurrent laryngeal papillomas can be achieved, but recurrence after longer treatment-free intervals is also possible.
