OBJECTIVE To know the different epidemiologic aspects of chronic inflammatory bowel disease (IBD) in the Northern area of the province of Huelva. MATERIAL AND METHODS we carried out a retrospective (1980-1996) and prospective (1996-2003) study of all patients diagnosed with IBD in the Northern area of Huelva, with 77,856 inhabitants. The distribution of(More)
OBJECTIVES 1. To study transfusion requirements in the Department of Gastroenterology of a Tertiary Referral Hospital, and their evolution over the last seven years. 2. To analyze risk factors associated with greater erythrocyte transfusion requirements. PATIENTS AND METHODS erythrocyte transfusion requirements were compared for patients admitted to the(More)
BACKGROUND & AIMS Hepatic vascular resistance is influenced by alpha-adrenergic tone. The aim of this study was to investigate the effects of continuous blockade of alpha-adrenoceptors with prazosin on hemodynamics, liver function, and renal function and whether the association of propranolol or furosemide enhances the portal pressure lowering effect of(More)
Physical exercise may improve the metabolic and haemodynamic responses, but the beneficial effects seem to depend on intensity, duration and muscular mass recruitment, which may vary between different types of protocols. This study was performed to evaluate the effects of two distinct moderate/long-term aerobic training protocols in the normal Wistar rat,(More)
This study was aimed at investigating whether the blockade of alpha 1-adrenergic receptors could reduce portal pressure in cirrhosis. Splanchnic and systemic hemodynamics were measured in 12 cirrhotic patients with esophageal varices at baseline and 1 hr after oral administration of 2 mg of prazosin (acute study). Measurements were repeated in 10 of these(More)
OBJECTIVES to assess the efficacy of thalidomide in the treatment of relapsed or refractory bleeding secondary to gastrointestinal angiodysplasia. MATERIAL AND METHODS we carried out a prospective study of 12 patients with bleeding due to gastrointestinal angiodysplasia refractory to conventional therapy who were treated with thalidomide. For each(More)
The initial experience in facial composite tissue allotransplantation has demonstrated that it is surgically feasible, safe, and reproducible. A robust team approach is necessary to warrant successful outcomes. We designed a specific face organ donation that limits facial donation requests followed by synchronous in situ dissection with the internal organs(More)
The analysis of ascitic fluid has been complicated by several recently reported new tests. To simplify this assessment, we evaluated nine parameters prospectively and simultaneously in blood and ascitic fluid from 285 patients with ascites to determine which were the most reliable for immediate diagnosis of the etiology of the ascites and of its(More)
