[Primary high-grade B-cell lymphoma of the CNS. Case report and review of the literature]. / Primäres hochmalignes B-Zell-Lymphom des ZNS. Fallpräsentation und Literaturübersicht.

We report the case of a 69-year-old patient referred to our clinic because of mania. When examined by neuroradiological imaging, there were lesions seen appearing and disappearing in different regions of the brain during a period of 2 months. Differential diagnosis of these changing lesions, progressive severe illness, and the role of glucocorticoid therapy concerning these lesions are discussed. The diagnosis of primary CNS lymphoma of the B-cell type could not made sure until autopsy.

Physicians' decision-making in incompetent elderly patients: a comparative study between Austria, Germany (East, West), and Sweden.

In order to investigate to what extent various determinants in the decision-making process for the treatment of severely ill incompetent patients are influenced by cultural and sociopolitical factors, 540 physicians in Austria, Germany (East and West), and Sweden, countries representing different healthcare systems, were surveyed using a self-administered questionnaire. It provided three case vignettes with different levels of information about the patient's treatment wishes in case of incompetence in a life-threatening situation. We found a general trend to a lower level of treatment in line with the patient's wishes when the information provided was more detailed. Remarkably, a substantial number of doctors did not comply with the patient's wishes. Ethical concerns and patient's wishes appeared as the most important factors whereas religious beliefs of the physician and hospital costs scored lowest. Because of the variability of treatment decisions and the importance of various factors determining the decision-making, an advance directive may be a feasible way of reducing the number of conflicts in critical situations. We recommend that ethical issues of clinical practice should be emphasized in the medical curriculum and in the training of physicians.

[Mifepristone (RU 486)]. / Mifepristone (RU 486).

The antiprogestin RU 486 converts the early pregnant uterus by increasing the sensitivity of the myometrium to prostaglandin (PG). These effects of antiprogestin have resulted in the development of nonsurgical procedures to abort embryos based on a combination of RU 486 and different PG-analogues administered vaginally or intramuscularly. RU 486 also has a softening effect on the cervix which may be used as pretreatment in second and third trimester abortions. The effects, mode of action, dangers, and the many other postulated clinical implications (like breast cancer, meningioma, ectopic pregnancy, fetal death in utero, induction of labour, initiation and promotion of lactation, endometrial or ovarian cancers, leukemia, Cushing's syndrome, uterine adenomyosis, acute uremia, leiomyosarcoma, hypertension, etc.) are discussed.
