["Online from tomorrow on please": comparison of digital framework conditions of curricular teaching at national university ENT clinics in times of COVID-19 : Digital teaching at national university ENT clinics]. / "Ab morgen bitte online": Vergleich digitaler Rahmenbedingungen der curricularen Lehre an nationalen Universitäts-HNO-Kliniken in Zeiten von COVID-19 : Digitale Lehre an nationalen Universitäts-HNO-Kliniken.

BACKGROUND: The corona crisis not only affects professional activities but also teaching and learning at universities. Buzzwords, such as e­learning and digitalization suggest the possibility of innovative teaching approaches that are readily available to solve the problems of teaching in the current COVID-19 pandemic. The current conversion to digital teaching is not primarily driven by didactic rationale or institutional strategy but by external circumstances. OBJECTIVE: The aim of the study was to determine the teaching situation at national university ENT clinics and academic teaching hospitals at the start of the virtual corona summer semester in 2020. MATERIAL AND METHODS: A specifically self-designed questionnaire regarding the local situation and conditions as well as nationwide scenarios was sent to all 39 national university ENT clinics and 20 ENT departments at academic teaching hospitals. RESULTS: A total of 31 university hospitals and 10 academic teaching hospitals took part in the survey. There were obvious discrepancies between available resources and effectively available digital teaching and learning contents. Further criticism was expressed regarding the communication with the medical faculty, the digital infrastructure and particularly the frequent lack of collaboration with central support facilities, such as media, didactics and datacenters. CONCLUSION: There are positive examples of successful transformation of classroom teaching to an exclusively virtual summer semester 2020 within the university ENT clinics; however, critical ratings of assistant professors and medical directors regarding the current teaching situation predominated. A time-critical strategic advancement is urgently needed.

[Change of vocal capacity due to different vocal loading tests]. / Veränderung der stimmlichen Leistungsfähigkeit durch verschiedene Stimmbelastungstests.

BACKGROUND: Vocal loading tests are an important element in the evaluation of vocal function. In Germany mostly tests with changes of loading intensity between 75 and 80 dB(A) or tests with continuous intensity of 80 dB(C) are used. MATERIAL AND METHODS: 17 subjects with healthy vocal function were analyzed in 3 test conditions (1. continuous loading of 80 dB(A), 2. loading with changes of intensity between 75 and 80 dB(A) and 3. without loading for 10 min) concerning DSI and visual analog scale in their time course. The measurements were performed pre, directly after and 20, 40 and 60 min after the loading. The loading test was performed using the German text "Das tapfere Schneiderlein". RESULTS: The data show that the deviation and percentages of lower values of the intended dB loading were much greater for the test with changes of intensity compared to the test with continuous loading. There were no significant differences of the DSI between both loading conditions. After the loading there was a drop of the DSI followed by a short recovery and a drop after 60 min. CONCLUSION: The loading test with continuous intensity appears more stable for healthy subjects and can be fulfilled more easily. Both tests show comparable courses concerning the DSI after the loading tests.
