Immediate and early trauma deaths are determined by primary brain injuries, or significant blood loss (haemorrhagic shock), while late mortality is caused by secondary brain injuries and host defence failure. First hits (hypoxia, hypotension, organ and soft tissue injuries, fractures), as well as second hits (e.g. ischaemia/reperfusion injuries, compartment(More)
Grading of the clinical status in patients with multiple trauma is important regarding the treatment plan. In recent years, 4 different clinical conditions have been described: stable, borderline, unstable, in extremis. Clinical parameters have been widely used in patients with penetrating injuries, and 3 categories were found to be important: shock,(More)
INTRODUCTION The availability of angular-stable plate/screw systems led to a euphoric use of these implants for the treatment of displaced proximal humerus fractures. The high implant costs seem to be justified by a potentially improved outcome. PATIENTS AND METHODS Thirty one patients (20 female, 11 male, mean age: 62+/-16 years) with two-, three- and(More)
Proinflammatory cytokines are important mediators of neuroinflammation after traumatic brain injury. The role of interleukin (IL)-18, a new member of the IL-1 family, in brain trauma has not been reported to date. The authors investigated the posttraumatic release of IL-18 in murine brains following experimental closed head injury (CHI) and in CSF of CHI(More)
To retrospectively evaluate the diagnostic value of 18F-FDG PET/CT in trauma patients with suspected chronic osteomyelitis. Thirty-three partial body 18F-FDG PET/CT scans were performed in 33 patients with trauma suspected of having chronic osteomyelitis. In 10 and 23 patients, infection was suspected in the axial and appendicular skeleton, respectively. In(More)
BACKGROUND Operative treatment of displaced proximal humeral fractures often results in poor functional outcome. We report a technique that provides improved rotational stability of the fracture and thus allows early functional treatment. METHODS Seventy-one consecutive patients (67 +/- 18 years) with displaced fractures of the proximal humerus (two-part,(More)
The mechanisms underlying cell death following traumatic brain injury (TBI) are not fully understood. Apoptosis is believed to be one mechanism contributing to a marked and prolonged neuronal cell loss following TBI. Recent data suggest a role for Fas (APO-1, CD95), a type I transmembrane receptor glycoprotein of the nerve growth factor/tumor necrosis(More)
The reduced responsiveness of monocytes or granulocytes toward endotoxin (endotoxin tolerance) during sepsis may depend on Toll-like receptors (TLR). The expression of TLR-2 and TLR-4 was measured on neutrophils (PMN) and monocytes from patients with sepsis (n = 21) or healthy controls (n = 12). Leukocytes (1 x 10/mL) were incubated at 37 degrees C with or(More)
The combination of multiple injuries and pelvic ring disruption often represents a devastating injury pattern. This study evaluates therapeutical strategies and the outcome of 174 severely traumatized patients with pelvic ring injury (ISS: 32.1±11.1 patients) over a 6-year period. Patients were divided into 3 groups according to their hemodynamic status at(More)
The present in vitro study investigates the cellular interaction of primary human osteoblasts with human and bovine solvent dehydrated cancellous bone (SDCB) discs. These are bio-implants from solvent dehydrated, gamma-irradiated preserved human and bovine cancellous bone, pre-treated to remove all cells, genetic components and water soluble proteins.(More)
