RESUMEN
We report the preoperative imaging findings of a 75 year old man with a large tumor of the lower abdomen. Computed tomography showed a large intraabdominal mass. In the differential diagnosis a gastrointestinal stromal tumor (GIST) or a metastasis of an unknown primary neoplasia were considered. Histology confirmed the diagnosis of a gastrointestinal stromal tumor (GIST).

We report the CT imaging findings of a 33 year old patient who presented to the emergency department with increasing right lower abdominal pain and shivering. She delivered a healthy baby two weeks ago after induction in the 39th week of pregnancy due to a large fetus. Two days after delivery, sterilisation was performed. Clinically the primary differential diagnosis was appendicitis. However, computed tomography revealed thrombosis of the right ovarian vein. Consequently, management was altered appropriately with administration of antibiotics as well as a therapeutic dose of low molecular weight heparin.

During four intensive observation periods in 1992 and 1993, dry deposition of nitrogen dioxide (NO(2)) and ammonia (NH(3)), and wet deposition of nitrogen (N) were determined. The measurements were carried out in a small, extensively managed litter meadow surrounded by intensively managed agricultural land. Dry deposition of NH(3) was estimated by the gradient method, whereas eddy correlation was used for NO(2). Rates of dry deposition of total nitrate (= nitric acid (HNO(3)) + nitrate (NO(3)(-))), total nitrite (= nitrous acid (HONO) + nitrite (NO(2)(-))) and aerosol-bound ammonium (NH(4)(+)) were estimated using deposition velocities from the literature and measured concentrations. Both wet N deposition and the vertical NH(3) gradient were measured on a weekly basis during one year. Dry deposition was between 15 and 25 kg N ha(-1) y(-1), and net wet deposition was about 9.0 kg N ha(-1) y(-1). Daily average NO(2) deposition velocity varied from 0.11 to 0.24 cm s(-1). Deposition velocity of NH(3), was between 0.13 and 1.4 cm s(-1), and a compensation point between 3 and 6 ppbV NH(3) (ppb = 10(-9)) was found. Between 60 and 70% of dry deposition originated from NH(3) emitted by farms in the neighbourhood. It is concluded that total N deposition is exceeding the critical load for litter meadows, is highly correlated to local NH(3) emissions, and that NH(3) is of utmost importance with respect to possible strategies to reduce N deposition in rural regions.
RESUMEN
According to the present study, in addition to the high accident rate, work in the building trade is characterized by intense muscle strain and constrained physical posture. In bricklaying, for example, a worker moves by hand up to seven tons of stone per shift. Consequently, various health complaints occur far more frequently in this occupation than in the other occupational groups, for instance, back complaints (71%), severe fatigue (58%), pain in the arms and hands (42%), headache (40%) and leg pain (34%). The most complained of factors include effects of the weather (74%), draft (50%), noise (55%), air pollution via dust (53%), skin contact with dirt and harmful substances (47%), moving heavy objects by hand (53%), adverse posture during work (47%), and a high risk of accidents (47%). Besides technical and organizational measures, the prevention of health impairments in employees in the building trade should be promoted by purposive care by works services of occupational medicine.

By means of inquiry and work place inspection health and ergonomic problems of jobs on diverse cash register systems were investigated, taking into account larger shopping centers as well as smaller self-service shops in various parts of Switzerland. A lot of work place inconveniences, e.g. current of air = 62%, tiresome goods handling = 31%, limited scope for movement = 30%, unsuitable seat = 23%, etc., as also construction and arrangement short comings related to definite types of cash register boxes, obviously resulting in an increased incidence of bodily ailments (back pain = 55%, arm pain = 43% visual troubles = 42%, etc.) were identified. Based on this investigation and on ergonomic analysis of different types of work place arrangements, recommendations were made on the planning and construction of cash register set-ups and on the organisation of work.
