Asymmetric cell divisions can be generated by the segregation of determinants into one of the two daughter cells. In Drosophila, neuroblasts divide asymmetrically along the apical-basal axis shortly after their delamination from the neuroectodermal epithelium. Several proteins, including Numb and Miranda, segregate into the basal daughter cell and are(More)
Phantom limb pain is a frequent consequence of the amputation of a body part. Based on the finding that phantom limb pain is closely associated with plastic changes in the primary somatosensory cortex and animal data showing that behaviourally relevant training alters the cortical map, we devised a sensory discrimination training programme for patients with(More)
BACKGROUND The management of acute pancreatitis (AP) is still based on speculative and unproven paradigms in many centers. Therefore, we performed an evidence-based analysis to assess the best available treatment. METHODS A comprehensive Medline and Cochrane Library search was performed evaluating the indication and timing of interventional and surgical(More)
BACKGROUND Enhanced recovery protocols may reduce postoperative complications and length of hospital stay. However, the implementation of these protocols requires time and financial investment. This study evaluated the cost-effectiveness of enhanced recovery implementation. METHODS The first 50 consecutive patients treated during implementation of an(More)
OBJECTIVE To review the current status of pancreatoduodenectomy for pancreatic cancer and chronic pancreatitis using evidence-based methodology. SUMMARY BACKGROUND DATA Despite improved results of pancreatoduodenectomy over the recent years, the reputation of the Whipple procedure and its main modifications has remained poor. In addition, the current(More)
OBJECTIVE We sought to determine the impact of positron emission tomography/computed tomography (PET/CT) on the management of presumed resectable pancreatic cancer and to assess the cost of this new staging procedure. SUMMARY BACKGROUND DATA PET using 18F-fluorodeoxyglucose (FDG) is increasingly used for the staging of pancreatic cancer, but anatomic(More)
The aim if this study was to compare percutaneous drainage (PD) of the gallbladder to emergency cholecystectomy (EC) in a well-defined patient group with sepsis related to acute calculous/acalculous cholecystitis (ACC/AAC). Between 2001 and 2007, all consecutive patients of our ICU treated by either PD or EC were retrospectively analyzed. Cases were(More)
This review assesses the presentation, management, and outcome of delayed postpancreatectomy hemorrhage (PPH) and suggests a novel algorithm as possible standard of care. An electronic search of Medline and Embase databases from January 1990 to February 2010 was undertaken. A random-effect meta-analysis for success rate and mortality of laparotomy vs.(More)
BACKGROUND Whereas early cholecystectomy is accepted as the optimal timing for surgery, the best treatment modality for acute cholecystitis (AC) is still under debate. In this series, we aimed to assess the current treatment of AC in a single institution. In addition, preoperative criteria were defined predicting the severity of inflammation. METHODS From(More)
BACKGROUND Bleeding complications during laparoscopic surgery are rare but probably underreported. The aim of the current study was to elucidate the clinical relevance of bleeding complications and major vascular injuries during standard laparoscopic procedures.
