Objective: To evaluate the effectiveness of systemic high-dose dexamethasone therapy for sudden sensorineural hearing loss in comparison to the previous treatment regimen at our clinic with systemic prednisone 100 mg daily for 7 days analyzed in a previous study. Methods: We conducted a retrospective review of an electronic patient data base of 79 patients with idiopathic sudden sensorineural hearing loss. The standard treatment was orally applied dexamethasone (1st to 3rd day: 40 mg daily, 4th to 6th day: 10 mg daily) in an ambulant setting. The primary endpoint was change in hearing threshold from the initial audiogram to an audiogram at least 4 weeks later. Factors that were analyzed included patient's age, interval between onset of symptoms and start of treatment, presence or absence of dizziness and tinnitus, the audiogram pattern, severity of hearing loss and hearing in the opposite ear. Hearing gain was expressed either as absolute or relative hearing gain. Functionally relevant recovery of hearing was defined as the final pure-tone average (PTA) of 30 dB or less (or the same as the PTA of the opposite ear ± 10 dB). Furthermore, we calculated the percentage of patients with complete, partial and no recovery as defined in the recently published Clinical Practice Guideline of the American Academy of Otolaryngology - Head and Neck Surgery Foundation. We then compared our results with the previous treatment regimen carried out at our clinic. Results: The average initial PTA hearing loss in the affected ear compared to baseline PTA of the unaffected ear was 51.5 ± 20.9 dB (mean ± SD). The mean absolute hearing gain was 44.4 ± 18.1 dB. The mean relative hearing gain was 86 ± 19%. Of the total, 87% had functionally relevant recovery of hearing. All of our patients showed partial (24%) or complete recovery (76%). No difference in recovery rate could be detected between patients with start of therapy within 24 h and patients with beginning of therapy within 7 days. We found a correlation between the severity of hearing loss and functionally relevant recovery. A mild hearing loss was noted in 34% of patients, with an average relative hearing gain of 89% and a functionally relevant recovery in 96% of them; the 9% of patients with initial deafness showed a mean relative hearing gain of 69% and a functionally relevant recovery in 43%. The audiogram pattern with low- or high-frequency hearing loss showed the best recovery rate; the poorest recovery rate was found in patients with initial deafness. Con-clusion: Application of high-dose orally applied dexamethasone seems to improve the recovery outcomes in comparison to prednisone 100 mg p.o. for 7 days.

In zahlreichen Ländern nimmt die Zahl von Organspenden nach Kreislaufstillstand (donation after circulatory determination of death, DCDD) zu, obwohl in der Medizinethik verschiedene Aspekte der DCDD kritisch diskutiert werden. In unserer Arbeit identifizieren wir ethisch relevante Aspekte der DCDD basierend auf einer umfassenden Literaturanalyse. Wir fokussieren dabei insbesondere auf zwei Aspekte: vorbereitende Maßnahmen und Irreversibilität des Todeskriteriums. Danach untersuchen wir in einer weltweit durchgeführten Auswertung von Webseiten von Organspende-Organisationen und einer begleitenden Umfrage, inwieweit diese ethisch relevanten Aspekte von DCDD in der Information potenziell spendewilliger Personen eine Rolle spielen. Es zeigt sich, dass in der Mehrheit der Webseiten der Organisationen auf die Thematik DCDD nicht oder kaum eingegangen wird, die befragten Verantwortlichen der Organisationen aber die Wichtigkeit der Aufklärung bei spendewilligen Personen betonen. Wir diskutieren diese Diskrepanz und weisen auf zentrale Punkte hin, über welche spendewillige Personen informiert werden sollen, wenn diese Form der Organspende in ihrem jeweiligen Land praktiziert wird. Zudem plädieren wir dafür, dass das Todeskriterium und die Prozeduren zur Todesfeststellung in der Transplantationsmedizin einheitlich sein sollen, um kritisch diskutierte Aspekte im Kontext der DCDD entschärfen zu können.

The sum of the skin surface lipids was determined by the extraction method according to Honsio, by the osmium acid test according to Brun et al. and by visual estimation. With the two latter methods it was possible to exclude with sufficient certainty a pronounced seborrhoea or sebostasis. The use of the osmium acid test did not offer any advantages over the visual judgment of skin types.
