    Notes: Abstract An activated renin-angiotensin system is a major risk factor for cardiovascular events. Angiotensin II acts on AT1 and AT2 receptors. Stimulation of AT1 receptors is associated with ¶• endothelial dysfunction, mainly as the consequence of an increased vascular production of superoxide radicals, ¶• vasoconstriction, ¶• platelet activation, ¶• enhanced release of plasminogen activator inhibitor-1, ¶• activation of immediate early genes c-fos and c-jun, ¶• myocyte hypertrophy, ¶• connective tissue formation, ¶• endothelin-1 synthesis, and ¶• activation of growth factors like PDGF and TGF-β1. ¶Stimulation of AT2 receptors can mitigate or abolish the growth promoting effects of AT1 receptor stimulation. The contribution of these effects – single or in combination – on the progression of atherosclerotic lesions, the phenomenon of restenosis and the process of remodeling in heart failure is being progressively elucidated. With increasing knowledge about these relationships the inhibition of AT1 receptors appears as a main target in preventive and reparative strategies in cardiovascular diseases.

    Description / Table of Contents: Summary The German Registry for Hearing Loss in Children (DZH) processes nationwide data from audiological centers. Coping with the accrued data and its subsequent management and analysis requires a high degree of security and control. To establish a nationwide registry it is necessary at an early stage to take into consideration the legal requirements of the participating states. Use of the DZH as an example demonstrates how a pragmatic solution can be reached. Special issues concerning data collection, transfer, storage and deletion, coding strategies to ensure anonymity, checking for duplicate entries, data separation, and automated data analysis and data protection are explained.
    Notes: Zusammenfassung Das Deutsche Zentralregister für kindliche Hörstörungen (DZH) verarbeitet bundesweit Daten von verschiedenen audiologischen Einrichtungen. Die Bewältigung der anfallenden Datenmengen, die nachfolgende Datenverwaltung und -analyse erfordern neben einer differenzierten und kontrollierbaren Verarbeitung ein Höchstmaß an Datensicherheit. Vor allem die länderübergreifende Struktur eines Registers erfordert schon bei der Planung engste Zusammenarbeit mit dem zuständigen Landesdatenschutzbeauftragten und auch mit den Landesdatenschutzbeauftragten anderer beteiligter Bundesländer. Am Beispiel des DZH wird demonstriert, wie eine kooperative Zusammenarbeit pragmatisch realisiert werden kann. Besonderheiten bei der Datenerhebung, Datentransfer, Speicherung und Löschung von Daten, technische Datenschutzmaßnahmen, Sicherstellung von Anonymität durch Codierungsstrategien, Duplikatsprüfung, Datentrennung und automatisierte Datenauswertung werden an Beispielen erläutert.
