Tubulization as an alternative to autologous nerve grafting successfully bridges relatively short nerve gaps. Digital nerve lesions are ideal for clinical outcome studies, but only a few data have been published so far. We are presenting our clinical experiences based on a review of the outcome and techniques in the current literature. Fifteen digital nerve(More)
Liver surgery and liver transplantation as well as circulatory shock are often associated with hepatic ischemia/reperfusion (I/R) injury. Recent evidence suggests that TNF-alpha plays a central role in I/R injury and, therefore, down-regulation of TNF-alpha seems to be a promising way to protect against the deleterious consequences of I/R. Endotoxin(More)
Little data are available concerning conduit repair of digital nerve lesions. We are presenting a prospective two-center cohort study on digital nerve reconstruction with collagen nerve conduits. The data are put into the context of a comprehensive review of existing literature. Over a period of 3 years, all consecutive digital nerve lesions that could not(More)
BACKGROUND The aim of this study was to induce therapeutic angiogenesis in ischemically challenged flap tissue by means of gene transfer. METHODS Isogenic rat fibroblasts were retrovirally transfected to produce platelet-derived growth factor (PDGF)-AA. Stable gene expression was monitored by PDGF-AA enzyme-linked immunosorbent assay. Eighty animals were(More)
Silicone implants have been used in breast augmentation for more than 45 years. Complications, in particular, capsular contracture, still occur with a high incidence. Titanium-coated polypropylene mesh (TCPM; TiLoop Bra®, pfm medical, Cologne, Germany) provides new opportunities for implant-based breast reconstruction. We investigated the influence of the(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)
INTRODUCTION In-hospital hypernatremia develops usually iatrogenically from inadequate or inappropriate fluid prescription. In severely burned patient an extensive initial fluid resuscitation is necessary for burn shock survival. After recovering of cellular integrity the circulating volume has to be normalized. Hereby extensive water and electrolyte shifts(More)
BACKGROUND Free tissue transfer (FTT) represents a clinical model to measure ischemia-reperfusion injury (IRI). This study was conducted to detect substances relevant for IRI after FTT. METHODS Eighteen patients underwent lower leg reconstruction with free myocutaneous latissimus dorsi muscles and were monitored clinically and by microdialysis technique.(More)
In case of blast injuries, traumatic tattoos can result from accidental inclusions of intradermal pigmented particles. To avoid these tattoos, especially in esthetical areas like the head and neck region and the hands, the primary goal in our treatment is to remove all particles and foreign bodies. Superficial foreign bodies can easily be removed by brushes(More)
Hibernoma is an uncommon benign fatty tumor that arises from the vestiges of fetal brown fat. We present a case report of a hibernoma of the back in a symptomatic 42-year-old man and describe the important clinical, histopathologic, and imaging findings. Computed tomography shows a well-defined hypodense mass with septations. Magnetic resonance imaging(More)
