RESUMO
During the last 53 abdominoperineal amputations of the rectum for carcinoma, we had to control 5 massive hemorrhages. 4 of which were due to a lesion of the presacral venous plexus and caused a mean blood-loss of 4750 ml. During a "normal" Mile's operation our 49 other patients lost an average of 1750 ml (median 1200 ml) of blood. The negative effects of this type of complication and the following need for massive transfusion is not only local, circulatory and pulmonary, but also due to the immunodepressive effects of massive transfusion. We describe the different methods of control of these hemorrhages and insist on the advantage of using sterilised metallic thumbtacks, a method which was described 1984 by doctor Wang Qinyao of Shanghai.

A medical examination and questionnaire in various office workplaces (N = 295) shows that in intensive work at visual display terminals rheumatic and asthenopic disorders are very frequent. Muscle pain and eye complaints are correlated. The incidence of eye disorders and visual acuity are related to lighting conditions (local and temporal oscillation of characters on the visual display) at the individual workplaces.

An apparatus for measuring the sharpness, the oscillation degree and the stability of characters of 8 different VDTs were developed. Furthermore the contrast of luminances between the essential surfaces was measured. The following results were observed: 2 VDTs had good ergonomic qualities, one was only sufficient and 5 VDTs had insufficient ergonomic light conditions.
