Monte Carlo techniques have become ubiquitous in medical physics over the last 50 years with a doubling of papers on the subject every 5 years between the first PMB paper in 1967 and 2000 when the numbers levelled off. While recognizing the many other roles that Monte Carlo techniques have played in medical physics, th…

Over the last 5 years an unexpectedly fast progress has been achieved in the field of xenotransplantation. This gives cause for substantial hope. Thus, the wish to use animal grafts for the replacement of human organs could become a reality. However, no results exist at present to suggest a biological and immunological…

This article gives the main parameters of amplifying screens manufactured in the USSR: the sensitivity, the resolution, the modulation depth, the noise. The technical level of Soviet screens is compared with the level of those manufactured by certain foreign companies. The measures taken to increase the technical level…

For the last 5 years the sociopsychiatric service of the public health administration of the city of Flensburg has been operating a kind of systemic family therapy. The theory of this method is described and placed in relationship with other family therapy theories. Some techniques of family therapy are demonstrated by…

During the last 10 years, we have treated 54 cases of fracture or dislocation of the lateral clavicle by transposing the coracoid process onto the clavicle. Recently, a postoperative musculocutaneous nerve injury was observed in 3 cases, all of which recovered spontaneously within 5 months. Our technique seems to entai…

We studied 69 patients with pm gastric cancer seen during the last 10 years. Lymph node metastasis was present in 40.6%; the 5-year survival was 77.1%. The macroscopic form and tumor long diameter showed a good correlation with the rate of lymph node metastasis and the prognosis. Especially with regard to the early can…

During the last 18 years we have treated few hundreds of patients with large incisional hernias. In more than the half of the cases our surgical procedure followed 3, 4 or even 5 previous surgical operations. In about 160 patients the hernia was connected with obesity, and in 25 females with pendulous abdomen. Our resu…
