A 66-year-old patient with terminal heart insufficiency (NYHA IV) received maximum medical therapy, but was also in need of an implantable-cardioverter-defibrillator (ICD). The ICD functioned flawlessly for the whole duration of implantation. It reverted several ventricular tachycardias with anti-tachycardial pacing alone, whereas some needed cardioversion as well. The patient died on the fourth day of hospitalization for a routine check of his ICD. The post-mortem examination revealed, that the ICD was deactivated and that the data had been erased after the patient's death. By reading off the raw data still stored within the ICD, the erased information could be restored. The stored EGMs showed traces of old ICD interventions as well as a permanent deactivation provoked by exposition to a magnetic field just hours before the patient's death. The problem of archiving and documenting the volatile electronic data inside the ICD is discussed. The need of a full autopsy after telemetric reading of the ICD data, including the explantation of the ICD aggregate and electrodes, as a means of quality assurance and under forensic aspects is emphasized. 相似文献

In schools humans are classified and categorized by other humans through the assessment of their actions and documents they produce there. This practice of differentiation essentially relies on contingent teacher judgements that are aggregated into marks, end-of-year reports or school graduation certificates. The article explores the formal and informal situations of teachers talking about their students and classes and making decisions about their school reports. While teachers share their judgements on pupils in informal staff-room conversations, the thereby generated knowledge does not necessarily result in social consequences. It does, though, in formal gatherings such as report conferences, where the judgements are ratified and fixated. The judgement of an individual teacher is hereby transformed into a grade given by the school. By analytically characterizing these social and numeric-administrative objectifications the article shows how judgements on pupils are kept reversible and simultaneously become solidified during the school year. 相似文献

Among those who would reform land use controls to achieve greater equity in urban development there has existed some disagreement between advocates of litigative and legislative approaches. The latter have looked to the Massachusetts Zoning Appeals Law, the A.L.I. Model Land Development Code, statutorily mandated housing planning, revisions of zoning enabling legislation or some variant of these, as the best way to the unpromised land. They have also noted that after almost a decade of litigation in which many victories were won for specific clients, litigators have little to show in the way of housing actually provided; although the educational impact of the case law on federal legislation and other legislative proposals has been significant. 相似文献
