BACKGROUND/AIMS The current standard for gastric emptying studies are radioactive isotope methods. [13C]breath tests have been developed as a nonradioactive alternative. The aim of this study was to validate a [13C]acetate breath test as a measure of gastric emptying of the liquid phase both in liquid and semisolid test meals by simultaneous(More)
BACKGROUND: Bacterial infections are associated with a high morbidity and mortality rate in patients with acute and chronic renal failure. Because C-reactive-protein (CRP) is elevated in many patients with renal failure, even in the absence of infection, procalcitonin (PCT) might be useful for the detection of systemic bacterial infections. This(More)
Laparoscopic cholecystectomy (LCCE) was gaining acceptance rapidly, when several institutions could demonstrate the safety of this minimal invasive treatment modality. Nevertheless prospective randomised studies still are missing to prove the advantages of this new treatment modality in contrast to open cholecystectomy. 77 patients with symptomatic(More)
Radiation necrosis of normal CNS tissue represents one of the main risk factors of brain irradiation, occurring more frequently and earlier at higher total doses and higher doses per fraction. At present, it is believed that the necrosis results due to increasing capillary permeability caused by cytokine release leading to extracellular edema. This process(More)
Several studies have been demonstrated that endotoxin is a potent stimulus of the acute inflammatory response following traumatic injury. Although numerous studies have indicated that the extent of surgical intervention correlates well with the inflammatory response, the potential role of endotoxin as a trigger under those conditions still remains unknown.(More)
BACKGROUND Tumor-related methylated DNA and circulating tumor cells (CTC) in the peripheral blood might be of prognostic importance in breast cancer. Thus, the aim of our study was to examine free methylated DNA and CTC in the blood from breast cancer patients and to correlate it with clinicopathological features known to influence prognosis. MATERIALS(More)
OBJECTIVE The purpose of the present study was to investigate prospectively the value of manometry, non-invasive techniques and endoscopic sphincterotomy in biliary type II and III patients with suspected sphincter of Oddi dysfunction. METHODS All patients (n = 31) had undergone a cholecystectomy from 1 to 45 years before entry into the study, and had a(More)
The aim of this clinical study was to investigate the time sequence between intraoperative and postoperative endotoxemia, changes in intramucosal pH(I), mediator release, and acute phase proteins and their relationship to postoperative infections. In 60 patients (median age 61 [33-72] years, male/female: 50/10) plasma levels of endotoxin, endotoxin(More)
Desmoid tumors are fibroblastic/myofibroblastic neoplasms, which originate from musculo-aponeurotic structures and are classified as deep fibromatoses. Despite their benign histologic appearance and lack of metastatic potential, desmoid tumors may cause aggres?sive local infiltrations and compression of surrounding structures. They are often associated with(More)
BACKGROUND Pancreatic cancer is the fourth most common cause of death in malignancies with an incidence of 8-12 cases per 100000 in western world. In spite of numerous modifications in therapeutical approaches, prognosis has not improved. METHODS In the last few years numerous studies have been performed to reduce tumor mortality with more radical(More)
