[1989 Basel Mammography Action].

To evaluate the compliance for a breast cancer screening program in the region of Basel, a mammography and a clinical examination has been offered free of charge to women between 40 and 60 years of age, especially to women with familial breast cancer. From September to November 1989, 602 women participated. Results were obtained from an epidemiologic questionnaire and a two-view mammography. The median age was 55.1 years. 70.2% of the women never had a mammography before. 28.8% indicated a history of familial breast cancer. So far 444 women have been evaluated. No pathological results were obtained in 84.8% In 10.7% a second examination has been recommended in the near future. In 4.5% the mammography led to an aspiration biopsy or surgical lumpectomy where 5 (1.2%) neoplasms have been detected. Due to the limited duration of the campaign and the invitation especially addressed to women at risk, our results are not comparable with large-scale screening campaigns known from the literature. Nevertheless, we succeeded to sensitize the female population for this kind of breast care. The overwhelming success shows that the basis for a large-scale screening program may exist.

[Transmission of force to the trabecular structures of the proximal end of the femur].

Normal use places stress on the femur from different directions and with variable intensity. All these forces are introduced as pressure forces through the cartilage in a trajectory framing cancellous structure whose elements are primarily charged axially with tension and pressure. The effects of these forces on these structures were analyzed with different methods. Often we only looked for single aspects of the introduction the of force or worked with experimentally acquire approximations. To analyze the conditions for an authentic femur, we examined the trabecular structures of a proximal femur with computed tomography. We had some indications that the trabecular structures are not built linearly, as shown by von Meyer, Wolff, Goss and Singh. In our study we found a significant deviation of the epiphyseal trabeculae from the metaphyseal alignment. This makes us believe that even later the area of the former epiphysis plays a certain role in the distribution of supporting structures beneath the charged surface meaning to adapt to the effective stress.

[Evaluation of bone lesions in malignant lymphomas].

Skeletal involvement of non-Hodgkin's lymphoma is found in 11-16%, in Hodgkin's disease in 7.6-34%. Primary lymphoma of bone has an incidence of 1-50% among all non-Hodgkin's lymphoma. The occurrence of skeletal lesions is higher in infants and children than in adults. Skeletal lesions caused by Hodgkin's and non-Hodgkin's lymphoma are mostly seen in the axial skeleton including the skull, whereas the primary lymphoma of bone seems to prefer a more peripheral site. The aggressiveness of the tumor growth can be measured by the method of Lodwick, by judging the edge characteristic, the penetration of the cortex, the periostal and sclerotic reaction. 3 examples illustrate this method. Conventional radiographs need only be performed when there is reason to believe a lesion is located in an area of structural importance, such as the neck of the femur, and in cases of skeletal pain of unknown origin.
