BACKGROUND/AIMS Nonalcoholic steatohepatitis is an emerging clinical problem among the obese population. However, risk factors of progression to advanced forms of liver disease in this particular group of patients remain to be defined. METHODS The demographics and clinical and histologic features of 46 obese patients were evaluated. The intrahepatic(More)
Terrorist urban mass casualty incidents (MCI) in the last 3 years have targeted commuter trains at rush hour, producing large numbers of casualties. Civilian care providers are usually not familiar with the types of blast injuries sustained by victims of these MCI. We focus on the injury patterns sustained by casualties of the Madrid, 11 March 2004,(More)
INTRODUCTION Pancreatic cancer presents the worst survival rates of all neoplasms. Surgical resection is the only potentially curative treatment, but is associated with high complication rates and outcome is bad even in those resected cases. Therefore, candidates amenable for resection must be carefully selected. Identification of prognostic factors(More)
INTRODUCTION Pancreatic neuroendocrine neoplasms (PNENs) are uncommon neoplasms with a wide spectrum of clinical behavior. The objective of this study was to assess in a large cohort of patients the relative impact of prognostic factors on survival. METHODS From June 2001 through October 2010, 1,271 patients were prospectively registered online(More)
The aim of this study was to explore the possible involvement of the angiopoietin (Ang)-1, -2/Tie-2 system in the development, growth, and metastases evolution of gastroenteropancreatic-neuroendocrine tumors (GEP-NETs). We prospectively examined the serum levels of Tie-2, Ang-1, and Ang-2 by ELISA in 42 patients with proven GEP-NETs and 27 controls. We also(More)
BACKGROUND Thymidylate synthase and hypoxia inducible factor-1α play a central role in the control of tumor progression. In the present study, we investigated the effect of three DNA polymorphisms within the thymidylate synthase gene and two within hypoxia inducible factor-1α on the prognosis of pancreatic cancer. PATIENTS AND METHODS A retrospective(More)
INTRODUCTION The aim of the study was to evaluate the relationship between the pre-surgical administration of a chemotherapy regime based on irinotecan or oxaliplatin and the development of non-alcoholic fatty liver disease (NAFLD) or sinusoidal obstruction syndrome (SOS), and the influence of these histological changes on the outcome of patients after(More)
INTRODUCTION Extended-spectrum beta-lactamase (ESBL) producing bacteria have been increasingly reported as causal agents of nosocomial infection worldwide. Resistance patterns vary internationally, and even locally, from one institution to the other. We investigated the clinical isolates positive for ESBL-producing bacteria in our institution, a tertiary(More)
PURPOSE Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare and heterogeneous tumors, and their biological behavior is not well known. We studied the presence and potential functional roles of somatostatin receptors (sst1-5), focusing particularly on the truncated variants (sst5TMD4, sst5TMD5) and on their relationships with the angiogenic(More)
