Insulin resistance and the metabolic syndrome are related to the severity of steatosis in the pediatric population with obesity.

Background: To determine the factors associated with an increased risk for severe steatosis (SS) and establish the Homeostatic Model Assessment-Insulin Resistance (HOMA-IR) as a screening tool.

Methods: A cross-sectional study was performed in obese children to assess the relationship between the metabolic syndrome (MetS) and glucose metabolism alterations (GMA) and the risk for severe steatosis.

Results: A total of 94 children (51 males) aged from six to 14 years were included.

Case of drug-induced acute pancreatitis produced by horsetail infusions.

Introduction: The most frequent causes of acute pancreatitis are biliary stones, alcohol consumption, smoking and tumors. Some of them do not have any established cause, and they are catalogued as idiopathic pancreatitis.

Case Report: We report the case of a 56-year-old woman with a history of bilateral adrenalectomy on hormone replacement therapy with corticosteroids, who has recurrent episodes of mild acute pancreatitis with an etiologic study (laboratory and imaging tests) without significant findings.

Prevalence of Primary Resistance of Helicobacter pylori to Clarithromycin and Levofloxacin in Southern Spain.

Background: The eradication of Helicobacter pylori (HP) using clarithromycin (CLA)-based triple therapy depends on the resistance of HP to antibiotics. The Maastricht III conference recommends the implementation of locoregional surveillance programmes for primary resistance of HP to CLA. In Andalusia, there are no previous data in this respect.

Hepatic steatosis and severity-related factors in obese children.

Background And Aim: Obesity is an important health-care problem in developed countries. It is considered a multisystemic disease, but it may also affect the liver, thus provoking non-alcoholic fatty liver disease. This disease has been less extensively studied among children than among adults.

[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.
