Determinants and impact of splanchnic vein thrombosis in acute pancreatitis.

Background: Splanchnic vein thrombosis (SVT) is a well-recognised though little-studied complication in acute pancreatitis (AP). SVT risk factors, its clinical consequences and the role of anticoagulation (AC) therapy is scarce.

Aims: To evaluate the incidence and natural history of SVT in AP.

[ESPEN Practical Guideline: clinical nutrition in liver disease].

Background: the Practical Guideline is based on the current scientific ESPEN guide on Clinical Nutrition in Liver Disease. Methods: it has been shortened and transformed into flow charts for easier use in clinical practice. The guideline is dedicated to all professionals including physicians, dieticians, nutritionists and nurses working with patients with chronic liver disease.

Factors associated with mortality in patients with infected pancreatic necrosis: the "surgery effect".

Severe acute pancreatitis complicated by infection is associated with high mortality. Invasive treatment is indicated in the presence of infected (suspected) pancreatic and/or peripancreatic necrosis (IPN) in the absence of response to intensive medical support. Step-up approach (SUA) has been demonstrated to lower complication rate compared to upfront open surgery.

Small intestinal bacterial overgrowth is common after gastrectomy but with little impact on nutritional status.

Background: Available evidence assessing the impact of small intestinal bacterial overgrowth (SIBO) following gastrectomy is limited.

Objectives: To evaluate the prevalence of SIBO after gastrectomy and its association with malnutrition. To describe the antibiotic treatment required to correct it and if nutritional status improves.

Determinants of Severity in Acute Pancreatitis: A Nation-wide Multicenter Prospective Cohort Study.

Objective: The aim of this study was to compare and validate the different classifications of severity in acute pancreatitis (AP) and to investigate which characteristics of the disease are associated with worse outcomes.

Summary Of Background Data: AP is a heterogeneous disease, ranging from uneventful cases to patients with considerable morbidity and high mortality rates. Severity classifications based on legitimate determinants of severity are important to correctly describe the course of disease.

[Nutritional support in patients with liver cirrhosis].

Given the liver's multiple synthetic, regulatory and detoxifying functions, one of the characteristics accompanying severe hepatocellular dysfunction is the presence of malnutrition. This disorder is highly frequent in liver cirrhosis, even in the relatively early stages of the disease. Independently of the cause of the cirrhosis, poor nutritional status is associated with a worse prognosis and therefore early intervention to correct nutrient deficiency can prolong life expectancy, improve quality of life, reduce complications and increase the probability of successful transplantation.

[Solitary pancreatic metastasis from renal carcinoma].

We present the case of a 60-year-old man with a history of left radical nephrectomy due to Fuhrman nuclear grade II renal carcinoma 8 years previously. Abdominal computed tomography was performed due to a closed abdominal injury, revealing a solid, 4-cm hypervascular mass in the head of the pancreas. The suspected diagnosis was pancreatic metastasis from renal carcinoma.

[A rare cause of gastric ulcer].

Drug-induced gastrointestinal tract lesions are becoming more frequent but are generally little known. Although a large number of drugs have gastrointestinal adverse effects, there are few characteristic patterns. Acute ischemic gastritis is an uncommon entity that is rarely distinguished from other forms of intestinal ischemia.

[Primary esophageal melanoma].

Primary Esophageal Melanoma (PEM) is an extremely rare neoplasm, with less than 270 cases described. Although clinical presentation is similar to any other esophageal neoplasm, MEP's behavior is more aggressive and fatal in most cases. We report two new cases of MEP diagnosed through endoscopy and anatomical-pathological analysis of collected biopsies.

[Distinct clinical presentations of a single medical entity: eosinophilic enteritis].

Eosinophilic enteritis is a rare disease characterized by eosinophilic infiltration of different wall layers of the gastrointestinal tract, from the esophagus to the rectum, by eosinophilic cells. The most frequently affected structures are the stomach and small intestine. The pathogenesis of eosinophilic enteritis is not well understood and is often related to a personal or familial history of atopy.

[Incidence and clinico-epidemiological aspects of ulcerative colitis in the area of the Hospital Costa del Sol].

Introduction: The incidence of inflammatory bowel disease, and of ulcerative colitis in particular, varies widely according to geographical area and has been reported to have increased in the last few years, although some of the differences observed may be due to the methodology employed.

Objectives: To determine the incidence of ulcerative colitis in our area and to compare it with that described in other areas of Spain and Europe, as well as to describe certain clinico-epidemiological aspects of this disease.

Material And Methods: A descriptive, prospective, population-based study was performed from 2000-2001 in patients diagnosed with ulcerative colitis in the catchment area of the Hospital Costa del Sol, with a population of 210,384 inhabitants.

Incidence of and factors associated with hepatocellular carcinoma among hepatitis C virus and human immunodeficiency virus coinfected patients with decompensated cirrhosis.

We compared the incidence of and factors associated with hepatocellular carcinoma (HCC) among hepatitis C virus (HCV)-monoinfected subjects and human immunodeficiency virus (HIV)/HCV-coinfected individuals, both with decompensated cirrhosis. In a retrospective study, a cohort of 180 individuals with HIV coinfection and 1037 HCV-monoinfected patients with decompensated HCV-related cirrhosis from eight centres in Spain were analyzed. HCC was found in 234 (23%) HCV-monoinfected subjects and in four (2%) HIV-coinfected subjects (p<0.

[Non invasive ventilation for acute exacerbation of chronic obstructive pulmonary disease: a meta-analysis].

Background And Objectives: The purpose of this study was: 1) To determine the effect of non invasive ventilation (NIV) in chronic obstructive pulmonary disease (COPD) patients with acute respiratory failure, and 2) To find out whether there are differences in the results according to the site where ventilation in applied.

Patients And Method: Meta-analysis of randomized controlled trials (RCTs) published included studies in MEDLINE, EMBASE, Cochrane Controled Trials Register and Teseo. Study selection included RCTs in COPD patients with acute respiratory failure with PaCO2 > 45 mmHg or pH < 7.
