[Massive pulmonary thromboembolism in a patient with Crohn's disease and latent tuberculosis treated with ustekinumab].

Inflammatory bowel disease (IBD) is a spectrum of chronic immune-mediated diseases that affect the gastrointestinal tract and other extraintestinal systems, behaving as a systemic disease. Thromboembolic phenomena are a frequent complication in IBD, because of hypercoagulability states associated with disease activity, and their presence has a negative impact on prognosis and patient survival. Due to this, the control of the inflammatory activity of IBD is one of the pillars in the control of thromboembolic events.

Introduction: Irritable bowel syndrome (IBS) is a chronic functional bowel condition with an average world prevalence of 11.2%. Is associated with multiple factors as female sex, young age, stress, anxiety and depression which can have a negative impact on quality of life.

[Arrhythmias and Sudden Death Risk in Hypertrophic Cardiomyopathy].

The risk of sudden death in hypertrophic cardiomyopathy is related to the presence of ventricular arrhythmias in most cases. Finding the best schemes to assess the probability of arrhythmic complications will remain a challenge for modern Cardiology. Meanwhile, the multifactorial approach is the best strategy to avoid the unnecessary implantation of devices such as the implantable cardioverter defibrillator.

[Colonic balantidiasis: report of a fatal case and review of the literature].

Balantidiasis is a zoonosis produced by Balantidium coli, which inhabits the large intestine of the pig and man. Infection is uncommon in humans and mainly affects the colon. It occurs more frequently in developing countries, tropical and subtropical regions.

[Jejunal phlebectasia as a cause of massive gastrointestinal haemorrhage].

Vascular abnormalities of the gastrointestinal tract are a common cause of gastrointestinal bleeding. Most of them are located within the reach of the upper endoscopy or colonoscopy, although once discarded, it forces to consider small bowel as the source of bleeding. The successful management of a gastrointestinal bleeding depends mainly on the timely location of the source of bleeding.

[Prevalence of histological types of gastric polyps in adult patients from a public hospital in Lima-Peru (2007 - 2016)].

Objectives: Establish the prevalence of gastric polyps detected by upper gastrointestinal endoscopy in patients older than 18 years old during the period from 2007 - 2016 in Cayetano Heredia Hospital.

Materials And Methods: Retrospective cross-sectional study, performed with data from the gastric biopsies reports of patients that have undergone upper gastrointestinal endoscopy between January 2007 and July 2016. Demographic data, endoscopic characteristics of the polyps and associated histological changes of the surrounding gastric mucosa were evaluated, which were subjected to statistical analysis using STATA v14.

Meckel's diverticulum is a rare clinical entity in clinical practice. However, it should be considered as an important differential diagnosis in patients with both obscure overt and occult gastrointestinal bleeding. Years ago, the evaluation of the small bowel was impossible without surgery, nowadays the development of new diagnostic methods has changed this horizon.
