Intensivmedizin aus Sicht des Unfallchirurgen

Severe injuries in patients of all ages and injuries in elderly multi-morbid subjects are a relevant medical and economic challenge. Optimal care of the polytraumatized patient can be best delivered by physicians specializing both in causal treatment of the injury or underlying disease and in intensive care. For care of critically ill injured patients, trauma surgeons with a certified specialty in intensive care medicine appear best suited. Of course, directing a surgical or trauma intensive care unit has to be full-time. Specialization of trauma surgeons (e.g., in the USA) has resulted in a considerable improvement in outcomes at least partly related to specialized trauma intensive care. Further improvement of trauma care relies on competent and innovative research not only in the fields of general intensive care, e.g., ventilation, but particularly in the complex aspects of the causality of the traumatic disease. An integrative view of the pathobiochemical, pathophysiological, and immunopathological sequelae of severe trauma under consideration of the various surgical and therapeutic strategies is the actual focus of research in surgical critical care medicine. Organ dysfunctions have to be modulated as they develop. Surgeons and trauma surgeons lead worldwide in this field of research. Obviously, competent research in polytrauma care requires competence in polytrauma intensive care.

BACKGROUND: Consequences of the volume outcome relationship are controversial. Objectification based on data analysis is strongly needed. The aim of this publication was to analyse the effects of volume outcome reallocations based on German inpatient data. METHOD: The analysis based on inpatient data of the Krankenhauszweckverband Koeln, Bonn und Region (Hospital Association of the Cologne and Bonn Region) of 2002 and 2005. Relevant data sets were identified according to the effects of current German regulations on volume outcome on the special fields liver transplant, kidney transplant, complex pancreatic surgery, and complex oesophageal surgery. RESULTS: The effects of current German regulations on volume outcome results differed greatly between the four surgical specialities. There were fewer effects on kidney transplant, but due to an already very high level of centralisation 34% (oesophagus) and 8% (pancreas) of the hospitals stopped related surgery. This affected 8.9% (oesophagus) and 2.2% (pancreas) of related cases. CONCLUSION: Concentration and the formation of specialised medical centres are results of the implementation of volume outcome relationships. The quality of medical treatment does not automatically improve from this development. It is necessary to analyse any correlation between quality and frequency of treatment or other criteria such as know-how, structure and process management, and multidisciplinarity.     

Die Rolle der Zytokine bei Knorpeldefekten und in der Knorpeltherapie

Cytokines play a pivotal role in the pathogenesis of degenerative joint disease but also in inflammatory conditions as well as osteoarthritis (OA) and rheumatoid arthritis (RA). A key role is attributed to interleukin-1 and tumor necrosis factor-α. Certain cytokines that can inhibit the activity of catabolic cytokines have great therapeutic potential and are currently being investigated in numerous clinical studies. Available scientific findings indicate that proinflammatory cytokines stimulate cartilage breakdown and blockade of these cytokines can protect the cartilage.     

The surgical risk of colectomy in patients with cirrhosis

The records of 54 patients with documented cirrhosis who underwent colectomy between January 1970 and January 1984 were studied to assess the operative risk and to determine the preoperative predictive risk factors. In-hospital mortality was 24 percent (13 patients), and postoperative complications occurred in 48 percent (26 patients). The risk of surgical intervention was significantly increased if encephalopathy, ascites, anemia, or hypoalbuminemia was present before operation. A simple operative risk index involving the presence of encephalopathy and ascites and the levels of hemoglobin and albumin is proposed to help distinguish a low-risk subgroup in whom postoperative mortality was 12.8 percent from a high-risk subgroup in whom postoperative mortality was 53.3 percent.     

Distraction Osteogenesis of Ankylosed Front Teeth with Subsequent Orthodontic Fine Adjustment

OBJECTIVE: Conventional therapeutic approaches to correct ankylosed anterior teeth in infraposition require compromises involving esthetics and function. The combined approach of distraction and early orthodontic fine adjustment, not yet established as a routine, promises better results concerning the bone conditions and gingival development. CASE HISTORIES: Both female patients had suffered a trauma to the front teeth during early mixed dentition resulting in ankylosed central incisors in infraposition. At the ages of 14 years and 2 months and 15 years and 2 months, respectively, we carried out segment distraction by means of a bone-supported internal distractor followed by orthodontic fine adjustment after having shortened the consolidation phase. Both ankylosed front teeth could be successfully aligned, leading to an increase in bone and harmonization of the gingival margin in the dental arch. At ten and 14 months after the conclusion of treatment, we observed only few deviations in the dental situation compared to posttherapeutic findings. CONCLUSION: From a functional and esthetic point of view, therapy involving combined orthodontics and surgery is superior to conventional therapy. Orthodontic fine adjustment should be considered as a continuation of the distraction procedure.     

Totale mesometriale Resektion

Abdominal radical hysterectomy (Wertheim operation), currently the standard surgical treatment for cervical carcinoma, is based on historical ideas of the female pelvic anatomy and of locoregional tumor spread. Total mesometrial resection (TMMR) uses new insights derived from developmental biology for a new oncological concept of radicality, i.e. resection of a malignant tumor within the borders of the morphogenetic unit of its origin. The morphogenetic uterovaginal unit that relates to the local spread of cervical carcinoma can be deduced from the embryological and fetal development. Anatomical structures that do not belong to this tissue unit can be left in situ despite close proximity to the tumor. When combined with nerve-sparing therapeutic lymph node dissection, TMMR yields a high locoregional control rate without adjuvant radiotherapy and with relatively little treatment-related morbidity.
