Despite the knowledge about sepsis for many years, the definition of sepsis is contested more than ever since the early 90th. Therefore, the comparability of many clinical investigations and scientific work in the past is still impaired. To define the entrance criteria for further clinical studies, in 1991 a consensus conference was held in the USA, but its recommendations have not found unequivocal acceptance. Therefore, these recommendations are presented and their meaning will be discussed.

Review Case Reports
[Primary hypertrophic pyloric stenosis. A are form and stomach outlet stenosis in the adult].
A 38-year-old white female with primary hypertrophic pyloric stenosis is presented. The patient was admitted to our service with a history of upper digestive tract pain and postprandial vomiting since her 17th year of life. ⋯ Primary hypertrophic pyloric stenosis in adults is a rare condition of unknown etiology. Only about 200 cases of primary hypertrophic pyloric stenosis in adults have been reported in the literature.

Four thesis related to economics of intensive care medicine are derived from an analysis of the intensive care unit of the university hospital of Basel, Switzerland, and the respective literature: (1) Intensive care medicine is costly but rationing can be avoided by rationalization. (2) Exemption or withdrawal of intensive care cannot be justified in the absence of accurate predictors of costs and outcomes of individual patients. (3) Intensive care physicians must not act as judges but on behalf of patients incapable of decision making. They must represent patients' interests vis-à-vis authorities and reimbursing institutions. (4) Analyses of cost-efficiency are instrumental for process improvement of intensive care, for negotiations on reimbursement and for the regulatory decisions of the authorities. Tools for economic analyses of intensive care medicine are therefore worthy of further development.

Despite the decreasing frequency of gastric cancer in most Western countries prognosis could not be improved by surgery alone in the past. Advanced tumor stage due to late diagnosis is one of the reasons for this observation. Contrary to breast and colorectal cancer, postoperative chemotherapy failed to improve prognosis in gastric cancer. ⋯ Intraperitoneal, adjuvant chemotherapy showed a positive impact on survival in Asian studies only, but was also used successfully as a part of a multimodality approach in Western phase II trials. Since neoadjuvant therapy proved to create downstaging of tumor size in some patients with advanced gastric cancer some working groups tried to influence prognosis of potentially resectable tumors by preoperative chemotherapy, surgical resection and postoperative, adjuvant therapy in the recent past. However, the efficacy of this therapeutic approach has to be reconfirmed in a controlled, phase III fashion.

A quantitative analysis of the injury severity of 40 patients with open pelvic fractures was performed. Data were analyzed using the Statistical-Analysis-System (SAS Institute Inc., Cary, NC) with regard to patients' age, gender, trauma mechanism, classification and nature of the pelvic injury, associated lesions, and mortality. Trauma-scoring included the Hannover-Polytrauma-Score [11], the Pelvis-Fracture-Scale [2] and the Pelvis-Score [19]. ⋯ The Pelvis-Score--with the variable "bleeding" defined as "major vessel lesion"--was significantly higher in the nonsurvivors than in the survivors (12.0 vs. 4.9; (p = 0.04; Mann-Whitney-test). In conclusion, in this retrospective study the Polytrauma-Score and the Pelvis-Score proved effective regarding some important aspects of the prognostic estimation of the general injury and the pelvic trauma, respectively. The Hannover-Pelvis-Fracture-Scale allows an exact documentation of the pelvic trauma as it pays proper attention not only to the fracture classification but especially to the soft tissue damage.
