Resuscitation and management of high-risk multiple trauma patients require a systematic and coordinated approach to diagnostic and therapeutic interventions. Clinical algorithms with branch chain decision logic can provide a clear and organized transformation of clinical standards for trauma care. Owing to their capability in formalization and standardization, algorithms define precisely the process of care and serve as a central interface within the system of quality assurance and quality control. ⋯ Special starting and ending point symbols make it possible to break down complex processes in several single interrelated algorithms. Inclusion of optional criteria checklists reduces the number of decision nodes and loops and minimizes the extent of a comprehensive algorithm. Clinical algorithms are an excellent tool for converting highly complex concepts of multiple trauma management into a logical, prioritized and systematic process of care.

The chondromyxoid fibroma as a benign bone tumour is described. The difficult but extremely important differential diagnosis from chondrosarcoma is discussed, and the question of the existence of malignant chondromyxoid fibroma is examined. ⋯ Experience with seven chondromyxoid fibromas and two tumours misdiagnosed as malignant chondromyxoid fibromas are described. In view of the clear definition of chondromyxoid fibroma and chondrosarcoma the term malignant chondromyxoid fibroma is not justified and should no longer be used.

The initial management of patients with multiple trauma requires a well-defined plan of action for immediate and adequate therapy, that ensures fast recognition of life-threatening conditions and injuries. While treatment protocols for specific situations and injuries are fairly well defined, there are few such concepts for the overall management process. Therefore, we designed a comprehensive algorithm for in-hospital trauma care to give priority-based guidelines to the trauma room physician. ⋯ The first algorithm starts with the initial assessment of immediate life-threatening disorders of A (airways), B (breathing) and C (circulation) and is followed by the early stabilization and maintenance of vital functions. It is followed by six interrelated flow charts, based on disturbed physiological functions (respiration, circulation) and anatomical injuries (thorax, abdomen, head/brain, spine/pelvic girdle/extremities), which are worked up simultaneously and repeatedly. This algorithm is not only intended as an overall guideline for use the management of severely injured patients, but is also indispensable for quality assurance.

A prospective study of 135 secondary operations (> 24 h after trauma) in patients with multiple injuries (ISS 40.6 pts) was performed to determine specific and unspecific indicators of the inflammatory response that may indicate the degree of risk of postoperative organ failure in these patients. On the morning of the operation each patients' data were recorded and blood samples were collected. Patients were divided in those in whom respiratory, renal and/or hepatic failure developed or preexisting organ failure worsened by more than 20% from baseline within 2 days after the operation and those who had no complications. ⋯ In 106 patients with secondary operations later than 72 h after trauma, neutrophil elastase, C-reactive protein and platelet count revealed the highest predictive accuracy, with cut-off values of 250 ng/ml, 11 mg/dl and 180 x 10(6)/ml, respectively. The combined accuracy of these three parameters in prediction of postoperative organ failure was 79% (sensitivity 73%, specificity 83%). In this group of patients the pO2/FiO2 ratio was of less value and blood pressure, heart rate, renal function parameters, lactate and coagulation parameters were of no value.(ABSTRACT TRUNCATED AT 250 WORDS)

Among the more than 50 scoring systems available for quantitative evaluation of injury severity, only a few have proved effective in clinical practice. In particular, the Revised Trauma Score (RTS), referring to physiological variables, has proved effective in preclinical use and otherwise, the Injury Severity Score (ISS), referring to anatomical data. There is a tendency in the development of new scoring systems to aim at higher predictive accuracy, forfeiting practicability. ⋯ When the scoring systems currently available are applied their specific deficiencies and limited evidence must be borne in mind. Nevertheless, they are an important scientific instrument for comparative examinations, and indispensable for quality assurance and economic analyses. To improve the predictive accuracy, biochemical parameters and chronic diseases should be considered, in addition to existing scores.
