A clinical application of the NSD-concept using iso-ret plans for the recording of radiation pneumonitis is reported. The conditions of an ascertainment of tolerance values for single organs by help of the Ellis formula are discussed. Of the examined patients with Hodgkin's disease who had been exposed to irradiation of the unaffected mediastinum, 42% suffered from radiogenic lung complications. The calculated iso-ret plans reveal a limitation of the pneumonitic shadow zone identical to the 1200-ret isoline. The data in literature are in accordance with these results.

Review of medical negligence cases: an essential part of residency programs.

Residency programs routinely review cases involving "morbidity and mortality." It would be a valuable experience to similarly review medical malpractice cases and the associated testimony by medical experts. When available, the cases reviewed in residency programs would be those in which faculty members at the same institution had testified. The faculty member in such cases would be intimately familiar with the case and able to share the knowledge necessary to take part in the legal process. This case review process would expose residents to the legal realities of medical practice, provide a forum for peer review of legal testimony by experts, and show residents how to participate in the legal system should the need arise.
