Gastrointestinal stromal tumors (GISTs) are the main mesenchymal neoplasms in the gastrointestinal tract. Tumor size, mitotic rate, and location correlate with potential malignancy and recurrence rate. Results of surgical treatment of gastric GIST are analyzed with emphasis on recurrence of disease after intermediate follow-up. From 1998 to 2006, a total of(More)
Ammonia is considered the major pathogenetic factor of cerebral dysfunction in hepatic failure. The correlation between total plasma ammonia and the severity of hepatic encephalopathy (HE), however, is variable. Because ammonia that is present in gaseous form readily enters the brain, the correlation with the grade of HE of the pH-dependent partial pressure(More)
OBJECTIVE To determine the exocrine pancreatic function in critically ill patients. DESIGN Prospective cohort study. SETTING Medical intensive care unit. PATIENTS A total of 18 critically ill patients (11 patients with septic shock according to the criteria of the American College of Chest Physicians/Society of Critical Care Medicine, 7 nonseptic(More)
Objective:We investigated the prevalence of hepatitis G-RNA (GBV-C/HGV-RNA), a recently cloned new flavivirus, and of antibodies to the envelope 2 antigen (anti-E2), a marker of past infection, in patients with autoimmune hepatitis, and compared it with the prevalence in patients with chronic viral hepatitis and healthy control individuals.Methods:Sera of(More)
Hepatitis G virus (GBV-C/HGV), a recently identified RNA virus adds to the risk of parenteral transmitted viral infections in hemodialysis patients. We studied the prevalence of GBV-C/HGV-RNA in serum and peripheral blood mononuclear cells (PMNC) by reverse transcription-polymerase chain reaction (RT-PCR) and determined antibodies against the envelope(More)
Severe impairment of exocrine pancreatic secretion has recently been demonstrated in a clinical study in sepsis and septic shock patients. The purpose of this study was to further evaluate involvement of the pancreas in the acute phase reaction in sepsis. Using a normotensive rat model of Pseudomonas pneumonia-induced sepsis, we assessed the expression of(More)
Sepsis-induced nitric oxide (NO) overproduction has been implicated in a redistribution of flow from the pancreas making it vulnerable to ischemic injury in septic shock. To test this hypothesis in a remote injury model of normotensive sepsis, we induced Pseudomonas pneumonia in the rat and used intravital video microscopy (IVVM) of the pancreas to measure(More)
TO THE EDITOR: A 49-yr-old woman with a history of carcinoid was referred to our nuclear medicine department for somatostatin receptor (SSTR) scintigraphy, In-DTPA-D-Phe-1-octreotide (In-OCT) (1, 2). Ten years earlier, the patient had had a resection of the sigma because of a carcinoid tumor. Now, 10 yr after the initial surgery, the patient had clinical(More)
BACKGROUND Endoscopes are well-known sources of bacterial transmission in health care facilities offering endoscopy services. The association between multidrug-resistant bacterial infections in patients who had undergone an endoscopic retrograde cholangiopancreatography procedure with reprocessed duodenoscopes has been much discussed.
