RESUMO
PURPOSE: The objective was to analyze the treatment and complications of the patients after a major amputation of the upper and lower extremities. Risk factors and predictors of a prolonged hospital stay should be outlined. METHODS: This is a retrospective study of a national Level-1 Trauma center in Germany. In a 10-year period, patients were identified by major amputations in the upper and lower extremities. The medical reports were considered and the results were split into four main groups with analysis on basic-, clinical data, the course on intensive care unit and the outcome. A recovery index was established. The patients' degree of recovery was summed up. Statistical analysis was performed. RESULTS: 81 patients were included. A total of 39 (48.1%) major amputations were carried out on the lower leg and 34 (42.0%) involved the thigh. There were two instances (2.5%) of hip joint disarticulation. 6 major amputations were done on the upper extremities (n = 3 on the upper arm, n = 3 on the forearm). 13.83 ± 17.10 days elapsed between hospital admission and major amputation. The average length of hospital stay was 38.49 ± 26,75 days with 5.06 ± 11.27 days on intensive care unit. Most of the patients were discharged home followed by rehabilitation. A significant correlation was found between the hospital length of stay and the increasing number of operations performed (p = 0.001). The correlation between the hospital length of stay and the CRP level after amputation was significant (p = 0.003). CONCLUSIONS: Major amputations in trauma patients lead to a prolonged stay in hospital due to severe diseases and complications. Especially infections and surgical revisions cause such lengthenings.
RESUMO
BACKGROUND: The clinical implementation of a new carbon-fiber-reinforced polyetheretherketon (PEEK) plate for distal radius fractures might offer advantageous properties over the conventional metallic devices. This includes similar elastic modulus to cortical bone, radiolucency, low artifacts on MRI scans and the lack of metal allergies. OBJECTIVE: The aim of this study was to evaluate the clinical results at 6-week and 12-month follow-up using either a new fixed angle (monoaxial) PEEK plate system or a fixed angle (polyaxial) titanium plate. METHODES: We included 26 patients (mean age 59.3) with displaced fractures of the distal radius (all AO types). Radiological and functional outcomes were measured prospectively at a 6-week and 12 month follow-up. RESULTS: We documented no cases of hardware breakage or significant loss of the surgically achieved fracture reduction with the usage oft the new PEEK device. Operating time was 101.0 min using PEEK versus 109.3 min in titanium plates, recorded times were including preparation, draping, and postoperative processing (ns, p 0.156). At the 6-week follow up the PEEK plate showed a trend for better range of motion and functional results (DASH-score, Mayo-wrist score, VAS) with no statistical significance. Results of 12 month follow up with PEEK showed comparable results with corresponding studies examining titanium plate after this period. CONCLUSION: First experience with PEEK plate osteosynthesis demonstrate quick clinical implementation with good clinical outcome and the advantage of excellent postoperative radiological assessment. At early follow-up PEEK even showed a trend for improved functional results.

Femoral neck fractures in young patients are rare but of high clinical relevance due to the complexity of risk factors and complications. Early stabilization and accurate reduction are of high priority. Femoral head-preserving stabilization by dynamic hip screws or threefold screw osteosynthesis are the methods of choice. Postoperative results should be closely controlled in every case in order to be able to treat possible complications in time.

The treatment of open fractures is a challenge for the attending surgeon. Depending on the severity, the risk of infection rises up to 50%. Local infection up to the point of sepsis can develop in spite of surgical and antimicrobial therapy. The present case demonstrates the case of an 18-year-old man who developed toxic shock syndrome (TSS) after an open ankle fracture. This potentially life-threating syndrome usually presents with the main symptoms of fever, hypotension and exanthema and is caused by toxins, such as toxic shock syndrome toxin 1 (TSST-1) and staphylococcal enterotoxins A-D. In some cases it is associated with cardiopulmonary decompensation and can rapidly progress to multiorgan failure.

The treatment of multiple trauma patients is a great challenge for an interdisciplinary team. After preclinical care and subsequent treatment in the emergency room the order of the interventions is prioritized depending of the individual risk stratification. For planning the surgery management it is essential to distinguish between absolutely essential operations to prevent life-threatening situations for the patient and interventions with shiftable indications, depending on the general condition of the patient. All interventions need to be done without causing significant secondary damage to prohibit hyperinflammation and systemic inflammatory response syndrome. The challenge consists in determination of the appropriate treatment at the right point in time. In general the early primary intervention, early total care, is differentiated from the damage control concept.

Knee joint infection represents an emergency case at every age. Joint infection occurs frequently after trauma or joint surgery. The infection can be caused by numerous bacteria, viruses, or yeasts; however, Staphylococcus aureus is identified as the cause in 85-95 % of joint infections. Early treatment is important for patient outcome. In addition to synovectomy and therapeutic arthroscopy, antibiotic therapy is essential and should be started after sample recovery.

The patella dislocation is defined as a non-recurring or recurrent dislocation of the patella from the patella surface of the femur. In general the patella dislocates in the lateral direction. Patella dislocations are subdivided in congenital, habitual or traumatic dislocations. Furthermore patella dislocations are differentiated in recurrent and chronic dislocations. Etiology of patella dislocations is not consistent and can be due to genu valgum, patella dysplasia or patella alta etc. Frequently the patella reposes spontaneously after dislocation. Besides examination of the knee, x-ray and magnetic resonance tomography belong to clinical diagnostics of the knee joint. Decision between conservative and operative therapy is addicted to accompanying injuries like fractures or ligamental injuries.

For therapy of blunt thoracic trauma in multiple injured patients, some studies have recommended prophylactic ventilation with kinetic therapy for 3-5 days. In contrast other clinics prefer to reduce the time of ventilation and to extubate as soon as possible. In this retrospective study our patient collective was investigated to find out if early extubation is linked to a higher complication rate. A total of 26 ventilated patients with severe thoracic trauma and an abbreviated injury scale score (AIS thorax) >3 were included in the study. The mean time of ventilation was 98.4 h and in patients without head injury 71.3 h. Out of 22 patients 4 had to be reintubated which had to be repeated for 2 patients. Of the patients 3 developed pneumonia but no cases of adult respiratory distress syndrome (ARDS) were observed. Of the patients 4 died due to other injuries. The mean stay on the intensive care unit was 6.3 days and the mean stay in hospital 22.6 days. Our findings indicate that even with early and aggressive weaning from a respirator with extensive lung contusions an adequate therapy of thorax trauma is possible without having a higher incidence of complications.

Inability to die by apoptosis is one of the reasons for the deregulated growth of tumour cells and the frequently observed failure of chemotherapy. In this study we thought to identify the common and functionally important characteristics responsible for the apoptosis resistance of pancreatic tumour cells. We analysed cell surface expression level of death receptors CD95 and TRAIL-R1-4 as well as the expression profile of sixteen apoptosis-relevant proteins in five pancreatic carcinoma cell lines Capan1, Colo357, PancTuI, Panc89 and Panc1. These data were evaluated in the context of sensitivity towards anti-CD95 and TRAIL-mediated apoptosis. Here we report that except for resistant Panc1 cells, which only marginally expressed CD95, all other cell lines showed comparable levels of CD95 and TRAIL receptors irrespectively of their apoptotic phenotype. Interestingly, we found that the elevated expression of FLIP, Bcl-x(L) and IAP in parallel with a downregulation of FADD and Bid was common for the resistant cell lines. Consequently, stable overexpression of XIAP, Bcl-x(L) or dominant negative FADD in sensitive cells significantly reduced the death receptor mediated apoptosis while the overexpression of Bid rendered the resistant cells sensitive.

The molecular alterations in tumour cells leading to resistance towards apoptosis induced by CD95 and TRAIL-receptors are not fully understood. We report here that the stimulation of the CD95- and TRAIL-resistant human pancreatic adenocarcinoma cell line PancTuI with an agonistic anti-CD95 antibody or TRAIL resulted in activation of protein kinase C and NF-kappaB. Inhibition of protein kinase C by Gö6983 sensitized these cells to apoptotic challenges and strongly diminished activation of NF-kappaB by anti-CD95 and TRAIL. Similarly, inhibition of NF-kappaB by MG132 or by transient transfection with a dominant negative mutant of IkappaBalpha restored the responsiveness of PancTuI cells to both death ligands. In the CD95 and TRAIL-sensitive cell line Colo357 the induction of protein kinase C and NF-kappaB following activation of CD95 and TRAIL-R was very moderate compared with PancTuI cells. However, pre-incubation of these cells with PMA strongly reduced their apoptotic response to anti-CD95 and TRAIL. Taken together, we show that activation of protein kinase C operates directly in a death receptor-dependent manner in PancTuI cells and protect pancreatic tumour cells from anti-CD95 and TRAIL-mediated apoptosis by preventing the loss DeltaPsim and Cytochrome c release as well as by induction of NF-kappaB.
