[Clinical experiences in supplementary treatment of pseudarthroses using electromagnetic potentials].
In 22 cases of pseudarthrosis following fractures of the limbs, 5 osteotomies and one fresh fracture of the lower leg postoperative treatment with the electro-magnetic alternating field according to Kraus/Lechner was performed in addition to osteosynthesis. Except in one unsuccessful case all patients showed a complete and obviously even quicker osseous bridging. Especially in preoperated and problem-cases such as pseudarthrosis of the femoral neck and defect-pseudarthrosis with inflammation of the tibia this method provided an additional success.
[Abrasion cytology of the stomach (author's transl)].
Cytological smears from 779 cases were examined over a three-year period, cell collection and cytological diagnosis being in separate hands (material sent in from outside). Three quarters of the cytological findings could be compared with the histological diagnosis: 68% of 194 histologically proven malignant tumours were diagnosed cytologically. The diagnostic accuracy varied between 53 and 74.4%, depending on experience and precision of the endoscopist. In 18 cytologically positive cases results were different from the histological diagnosis. Initial diagnosis of malignant tumour by cytology was made in 3.6% of cases. Subsequently repeated biopsies or histological examination of surgical specimens confirmed the diagnosis.

[Electronic volume analysis of cell nuclei in the gastric mucosa].
A trial was conducted for mechanical and objective analysis of gastric mucosal specimen concerning suspicion of malignancy by means of electronic nuclear volume analysis. 16 specimen of normal and 10 specimen of malignant gastric mucosa were investigated. The mean nuclear volume was 37.3 mu3 in normal and 54.8 mu3 in carcinomatous mucosa. The difference with p less than 0.00005 is highly significant.
