[Use of geographic information systems (GIS) in strategic planning of surgical capacity within a hospital organization].

State of the art planning of clinical work means for hospitals outlining a catalog which is a convincing as it is profitable. Furthermore, it should easily remembered as a "brandname" by patients and consultants. A catalog like this is built up on the basis of an analysis of structures of work, costs, income, needs of the environment, the own work capacity and the surrounding competitors.

[Estimation for bugeting and evaluation of surgical procedures within the scope of comparative hospital administration. Value of LKA, PPR and DRG systems].

Comparison of costing and performances of individual departments or hospitals are required by the statute book of social affairs (Sozialgesetzbuch V; SGB V), but have not been fully introduced in Germany. LBK Hamburg, a trust of 8 hospitals with 17 surgical departments, evaluated the significance of performance and cost-accounting systems such as performance and cost-accounting (LKA), nursing staff regulation (PPR), and the diagnosis-related group system in order to distribute a three-year budget (1996-1998) and to compare, e.g.

Increased activation of isolated intestinal lamina propria mononuclear cells in inflammatory bowel disease.

Normal human lamina propria lymphocytes are in a heightened state of activation compared with peripheral blood with regard to cell-surface activation antigen expression (transferrin receptor, interleukin-2 receptor, 4F2) and the increased spontaneous secretion of immunoglobulins in vitro. This study evaluates the cell-surface expression of activation-associated antigens in different subpopulations of isolated colonic lamina propria mononuclear cells in inflammatory bowel disease. In pilot studies using three-color flow cytometry, autofluorescence was observed that was emitted by unstained lamina propria mononuclear cells, which interfered with both the sensitivity and the specificity of the analyses.
