A new telerobotic arm was evaluated in different microsurgical procedures. The system consisted of a robotic arm bearing a microsurgical forceps controlled by a joystick-like master unit operated by the surgeon's hand. The robotic arm functioned as an operating as well as assisting instrument. Advantages of the system were its precise functioning, which was… (More)
Verletzung durch Blitzschlag ist einer der häufigsten Unfälle durch ein Naturphänomen. Das Risiko, durch einen Blitz getroffen zu werden, ist jedoch sehr gering. Ungeschützte Objekte auf einem freien Feld sind dieser Naturgewalt am ehesten ausgeliefert. Obwohl Blitzverletzungen meist den gesamten Körper betreffen, sind Zentralnerven- und… (More)
BACKGROUND Injections of single-dose vascular endothelial growth factor (VEGF)(165) have been advocated as a therapeutic tool for angiogenesis in ischemic flaps. We challenged this thesis by employing both VEGF(165) and vascular endothelial growth factor receptor-1 (VEGFR-1) (for competitive inhibition of VEGF signal transduction) in different experimental… (More)
Summary. Infections that develop as a complication of minor injuries to the hand, frequently are underestimated by the patient or by the physician initially consulted. Between 1990 and 2000, we have treated 172 in-patients as a result of this underestimation. In a retrospective study we have tried to evaluate the economic consequences. According to our… (More)
Frequently, the timely onset of adequate treatment is delayed when a hand infection is the result of minor trauma. The patients as well as the physicians are tempted to underestimate this complication. To prove that certain forms of trauma correlate with the degree of underestimation, we have prospectively studied the cases of 105 patients who required… (More)
The activities in serum of alkaline phosphatase, gamma-glutamyltransferase, glutamate dehydrogenase, glutamic pyruvic transaminase and cholinesterase were compared after complete biliary obstruction (CBO) and choledochocaval fistula (CCF) in the rat. CCF was used as a model of complete biliary retention without bile stasis and without increased pressure in… (More)
Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare vasoproliferative lesion of uncertain aetiology, involving the skin and subcutaneous tissue. The predilection of the tumour-like lesion is for the head and neck region. Radical surgical excision is still regarded as the most effective treatment. We present the case of a 33-year-old female with… (More)
The authors' experience indicates that good functional results are achievable in cases with wide resection of the knee extensor mechanism. They report a low-grade myxoid fibrosarcoma patient in whom a one-stage functional reconstruction was carried out by transfer of a free latissimus dorsi flap without secondary surgical procedures.
BACKGROUND Although it was initially assumed that erythropoietin (EPO) was a hormone that only affected erythropoiesis, it has now been proposed that EPO plays an additional key role in the regulation of acute and chronic tissue damage. METHODS/DESIGN This is a large, prospective, randomized, double-blind, multi-center study, funded by the German Federal… (More)
A rare case of ring avulsion injury with avulsion of both digital arteries yet without external soft tissue, tendon or skeletal injury in a 29 year-old man is reported.
