Via Laryngo-Rhino-Otologie Laryngorhinootologie DOI: 10.1055/a-1307-3872 Im Oktober 2020 vermeldeten die Laienpresse, aber auch einige medizinische Journale und Internetseiten, die angebliche Entdeckung einer neuen Speicheldrüse im Nasenrachen ausgehend von Positronen-Emissions-Tomografie-Computertomografie-Untersuchungen mit Liganden für das Prostata-spezifische Membranantigen (PSMA-PET/CT). Als interdisziplinäre Gruppe aus den Fachbereichen Anatomie, Pathologie, Nuklearmedizin und HNO-Heilkunde kommen wir zu der Ansicht, dass hier eine Anhäufung von kleinen Speicheldrüsen beschrieben wird. Kleine Speicheldrüsen im Nasenrachen und peritubar sind mindestens seit 1866 bekannt und immer wieder in der Literatur und in Lehrbüchern beschrieben. Das PSMA-PET/CT könnte aber geeignet sein, bei einer Bestrahlungsplanung funktionell relevante Anhäufungen von Schleimhautspeicheldrüsen, wie beispielsweise im Bereich des Nasenrachens, besser darzustellen und zu schonen. Dies sol lte in klinischen Studien geprüft werden.

Via leak of cerebrospinal fluid Related Articles Trends in cerebrospinal fluid leak rates following the extended endoscopic endonasal approach for anterior skull base meningioma: a meta-analysis over the last 20 years. Acta Neurochir (Wien). 2020 Nov 14;: Authors: Zamanipoor Najafabadi AH, Khan DZ, Muskens IS, Broekman MLD, Dorward NL, van Furth WR, Marcus HJ Abstract OBJECTIVE: The extended endoscopic approach provides unimpaired visualization and direct access to ventral skull base pathology, but is associated with cerebrospinal fluid (CSF) leak in up to 25% of patients. To evaluate the impact of improved surgical techniques and devices to better repair skull base defects, we assessed published surgical outcomes of the extended endoscopic endonasal approach in the last two decades for a well-defined homogenous group of tuberculum sellae and olfactory groove meningioma patients. METHODS: Random-effects meta-analyses were performed for studies published between 2004 (first publications) and April 2020. We evaluated CSF leak as primary outcome. Secondary outcomes were gross total resection, improvement in visual outcomes in those presenting with a deficit, intraoperative arterial injury, and 30-day mortality. For the main analyses, publications were pragmatically grouped based on publication year in three categories: 2004-2010, 2011-2015, and 2016-2020. RESULTS: We included 29 studies describing 540 patients with tuberculum sellae and 115 with olfactory groove meningioma. The percentage patients with CSF leak dropped over time from 22% (95% CI: 6-43%) in studies published between 2004 and 2010, to 16% (95% CI: 11-23%) between 2011 and 2015, and 4% (95% CI: 1-9%) between 2016 and 2020. Outcomes of gross total resection, visual improvement, intraoperative arterial injury, and 30-day mortality remained stable over time CONCLUSIONS: We report a noticeable decrease in CSF leak over time, which might be attributed to the development and improvement of new closure techniques (e.g., Hadad-Bassagasteguy flap, and gasket seal), refined multilayer repair protocols, and lumbar drain usage.

Via hno Related Articles [Reducing tinnitus intensity : Pilot study to attenuate tonal tinnitus using individually spectrally optimized near-threshold noise]. HNO. 2020 Nov 13;: Authors: Schilling A, Krauss P, Hannemann R, Schulze H, Tziridis K Abstract BACKGROUND: Around 15% of the general population is affected by tinnitus, but no real cure exists despite intensive research. Based on our recent causal model for tinnitus development, we here test a new treatment aimed at counteracting the perception. This treatment is based on the stochastic resonance phenomenon at specific auditory system synapses that is induced by externally presented near-threshold noise. OBJECTIVE: This pilot study will investigate whether individually spectrally adapted noise can successfully reduce chronic tonal/narrow-band tinnitus during stimulation. MATERIALS AND METHODS: Hearing loss (HL) as well as tinnitus pitch (TP) and loudness (TL) were audiometrically measured in 22 adults (46.6±16.3 years; 4 women) with tinnitus. Based on these measurements, up to eight different noise stimuli with five intensities (-20 to +20 dB SL) were generated. These were presented for 40 s each via audiologic headphones in a soundproof chamber. After each presentation, the change in TL was rated on a five-level scale (-2 to +2). RESULTS: We found patients (n = 6) without any improvement in their TL perception as well as patients with improvement (n = 16), where stimulation around the TP was most effective. The groups differed in post-hoc analysis of their audiograms: the effectiveness of our new therapeutic strategy obviously depends on the individual HL, and was most effective in normal-hearing tinnitus patients and those with mild HL. CONCLUSION: Subjective TL could be reduced in 16 out of 22 patients during stimulation. For a possible success of a future therapy, the HL seems to be of relevance.

Via Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial Related Articles Risk factors for medication-related osteonecrosis of the jaw and salivary IL-6 IN cancer patients. Braz J Otorhinolaryngol. 2020 Oct 25;: Authors: Kemp APT, Ferreira VHC, Mobile RZ, Brandão TB, Sassi LM, Zarpellon A, Braz-Silva PH, Schussel JL Abstract INTRODUCTION: Medication-related osteonecrosis of the jaws is a severe complication of the use of antiresorptive and antiangiogenic therapy, with limited treatment options and great impact on patient's quality pf life. OBJECTIVE: The aim of this study was to assess the risk factors associated with medication-related osteonecrosis of the jaws in oncologic patients undergoing bisphosphonate treatment. In addition, salivary levels of interleukin-6, IL-6, were measured to investigate their association with severity and risk of medication-related osteonecrosis of the jaws. METHODS: Case-control study with 74 patients with bone metastases from solid tumors and multiple myeloma was included. Patients were divided into three groups: 1) those undergoing bisphosphonate treatment with medication-related osteonecrosis of the jaws; 2) those undergoing bisphosphonate without medication-related osteonecrosis of the jaws; and 3) those with bisphosphonate pretreatment. The demographic and medical data of the patients were collected to assess risk. The clinical evaluation was performed to diagnose medication-related osteonecrosis of the jaws and unstimulated saliva was collected for quantification of IL-6. RESULTS: As result, it was observed that patients diagnosed with medication-related osteonecrosis of the jaws were submitted to higher number of bisphosphonate doses (p = 0.001) and monthly infusion protocol (p = 0.044; OR = 7.75). Patients who did not have routine followup with specialized dentists during therapy with bisphosphonate and smoking were associated with medication-related osteonecrosis of the jaws (p = 0.019; OR = 8.25 and p = 0.031; OR = 9.37 respectively). Group 1 had a higher frequency of treatment with chemotherapy and corticosteroids concomitant with bisphosphonate, and surgical dental procedures (p = 0.129). Salivary IL-6 levels showed no statistically significant difference between the groups (p = 0.571) or association with medication-related osteonecrosis of the jaws severity (p = 0.923). CONCLUSION: A higher number of bisphosphonate cycles, monthly infusion protocol, no dental follow-up for oral health maintenance and smoking were associated with medication-related osteonecrosis of the jaws. Specialized dental follow up during bisphosphonate treatment has been shown to be an important factor in preventing this complication.

Eur Arch Otorhinolaryngol. 2020 Nov 13;: Authors: Koparal M, Kurt E, Altuntas EE, Dogan F Abstract PURPOSE: We assessed the effects of COVID-19 infection on nasal mucociliary activity. METHODS: The study was conducted in the pandemic wards of Adiyaman University Training and Research Hospital during April and May 2020. All patients admitted to the COVID-19 pandemic wards during the study period were invited to participate in the study. The study included 40 adults who agreed to participate and underwent a mucociliary clearance test successfully. The primary outcome was mucociliary clearance time and the secondary variables of interest were age, sex, and sino-nasal outcome test-22 scores. The control group included 40 concomitant healthy patients who visited the outpatient ear, nose and throat clinic with non-nasal symptoms. RESULTS: The study included 40 COVID-19-positive patients and 40 healthy controls. The mean mucociliary clearance times of the study (15.53 ± 5.57 min) and control (9.50 ± 3.70 min) groups were significantly different (Z = 4.675, p < 0.001). However, the mucociliary clearance time was not significantly different between males and females (t = 0.590, p = 0.558). CONCLUSIONS: Nasal mucociliary clearance time was prolonged in COVID-19 patients compared to healthy controls. Thus, we conclude that smell and taste are crucial symptoms that should not be overlooked in patients suspected of COVID-19 disease.

Eur Arch Otorhinolaryngol. 2020 Nov 13;: Authors: Tran LV, Psaltis A, Le LT, Siow JK Abstract PURPOSE: The distance between the anterior wall of the maxillary sinus and the nasolacrimal duct has been classified into three types by Simmen, in which type I (< 3 mm) is the least feasible for a prelacrimal approach. The aim of our study is to present a surgical technique which overcomes the anatomical limitation of the narrow lacrimal recess (type I) in the management of inverted papilloma in the maxillary sinus. METHODS: Case series. RESULTS: Eight patients with type I lacrimal recess underwent surgical resection for inverted papilloma in the maxillary sinus via a prelacrimal approach. The technique is described in detail in the article and essentially involves exposure of the nasolacrimal duct using a diamond burr. Complete tumor excision was achieved in all cases through this access, with no significant intra-operative complications. CONCLUSIONS: This prelacrimal approach technique is safe and effective for the management of inverted papilloma in maxillary sinuses with a type I lacrimal recess configuration.

Via radioactive iodine Related Articles Improvement of lenvatinib-induced nephrotic syndrome after adaptation to sorafenib in thyroid cancer: A case report. World J Clin Cases. 2020 Oct 26;8(20):4883-4894 Authors: Yang CH, Chen KT, Lin YS, Hsu CY, Ou YC, Tung MC Abstract BACKGROUND: Target therapy is licensed by United States Food and Drug Administration on certain cancers. Both sorafenib and lenvatinib are tyrosine kinase inhibitor and indicated on radioactive iodine (RAI)-refractory differentiated thyroid cancer (DTC). Lenvatinib is more effective in cancers' control than sorafenib, but causes more nephrotoxicity than sorafenib does. This case is the second published case about the serial adaptions from lenvatinib to sorafenib for improving the proteinuria and, meanwhile, achieving the therapeutic goal. CASE SUMMARY: A 56-year-old man suffered from bilateral edematous lower extremities after 1-mo prescription of lenvatinib of 20 mg/d for RAI-refractory DTC. Aside from this symptom, he also developed hypertension. His laboratory showed grade-3 proteinuria (estimated 24-h urine protein: 9993 mg), hypoalbuminemia and hypercholesterolemia. Anti-vascular endothelial growth factor (VEGF) therapy-induced nephrotic syndrome was impressed. After reduced dosage of lenvatinib of 10 mg/d and related symptomatic drugs, limited improvement was observed in both adverse effects and caner control. Under this condition, we substituted sorafenib of 400 mg/d for lenvatinib of 10 mg/d. After a 5-mo prescription, not only hypertension and peripheral edema were greatly improved, but also proteinuria was improved from grade three to grade one (estimated 24-h urine protein: 962 mg). At the same time the cancer control was achieved, judged from computed tomography and laboratory evidence [thyroglobul in (Tg) before prescription of sorafenib: 354.7 ng/mL; Tg after prescription of sorafenib: 108.9 ng/mL]. CONCLUSION: Adaption from lenvatinib to sorafenib is a feasible method to improve the anti-VEGF therapy-induced nephrotic syndrome and achieve the therapeutic goal at the same time.

Via oto-rhino-laryngologie Related Articles [Role and effectiveness of radioactive-iodine therapy for the treatment of Grave's disease]. Pan Afr Med J. 2020;36:341 Authors: Sellem A, Elajmi W, Mhamed RB, Oueslati N, Ouertani H, Hammami H Abstract The treatment of Graves' disease is based on three therapies: medical treatment with synthetic antithyroid agents, surgery and radioactive-iodine therapy. The purpose of our study was to study the role and effectiveness of radioactive-iodine therapy for the treatment of Graves' disease. We conducted a retrospective, descriptive study of the epidemiological, clinical, paralclinical and therapeutic features of 54 patients with Graves' disease managed and treated with iodine-131 as well as of their short- and medium-term remission rate. The sex ratio was 0.45. The average age of patients was 38,33 ± 12.7 years. The most common functional signs were weight loss, tremors and palpitations. Mean FT4 was 54,51 ± 19,56 ng/dl (ranging from 8,90 and 100). Mean TSHus was 0,074 ± 0,29 µIU/ml. Synthetic antithyroid drugs were used in 49 patients; 83,67% of cases had persistent hyperthyroidism. Radioactive-iodine therapy was used as first-line therapy in 9,3% of cases and as second-line therapy in 90,7% of cases. Mean activity was 13,29 mCi ± 1,46 ranging from 10 to 15 mCi. The first assessment of hormonal status was performed after an average post-treatment period of 1,91 months; 29 patients (53,7%) achieved remission (eu- or hypo-thyroidism). After a 12 month-follow-up, patients' course was marked by remission in 88,88% of cases (euthyroidism in 14,8% and hypothyroidism in 74% of cases). Radioactive-iodine therapy is an effective treatment for Graves' disease. High radioactive iodine dose provides high remission rate. PMID: 33193994 [PubMed - in process] View on the web Inoreader.

Via cortical auditory Related Articles Cortical Stimulation Induces Excitatory Postsynaptic Potentials of Inferior Colliculus Neurons in a Frequency-Specific Manner. Front Neural Circuits. 2020;14:591986 Authors: Qi J, Zhang Z, He N, Liu X, Zhang C, Yan J Abstract Corticofugal modulation of auditory responses in subcortical nuclei has been extensively studied whereas corticofugal synaptic transmission must still be characterized. This study examined postsynaptic potentials of the corticocollicular system, i.e., the projections from the primary auditory cortex (AI) to the central nucleus of the inferior colliculus (ICc) of the midbrain, in anesthetized C57 mice. We used focal electrical stimulation at the microampere level to activate the AI (ESAI) and in vivo whole-cell current-clamp to record the membrane potentials of ICc neurons. Following the whole-cell patch-clamp recording of 88 ICc neurons, 42 ICc neurons showed ESAI-evoked changes in the membrane potentials. We found that the ESAI induced inhibitory postsynaptic potentials in 6 out of 42 ICc neurons but only when the stimulus current was 96 μA or higher. In the remaining 36 ICc neurons, excitatory postsynaptic potentials (EPSPs) were induced at a much lower stimulus current. T he 36 ICc neurons exhibiting EPSPs were categorized into physiologically matched neurons (n = 12) when the characteristic frequencies of the stimulated AI and recorded ICc neurons were similar (≤1 kHz) and unmatched neurons (n = 24) when they were different (>1 kHz). Compared to unmatched neurons, matched neurons exhibited a significantly lower threshold of evoking noticeable EPSP, greater EPSP amplitude, and shorter EPSP latency. Our data allow us to propose that corticocollicular synaptic transmission is primarily excitatory and that synaptic efficacy is dependent on the relationship of the frequency tunings between AI and ICc neurons.
