High ulcerative colitis and Crohn's disease ratio in a population-based registry from Córdoba, Argentina.

Background: Few studies have described the epidemiology and clinical behavior of inflammatory bowel disease (IBD) in South America. The aim of this study was to report on the prevalence, phenotype, and treatment of patients with IBD diagnosis in Capital Department of the Province of Córdoba, Argentina.

Methods: Data from adult patients (≥ 18 years-old) with IBD diagnosis that attended 12 public or private centers between 05/2014 and 05/2019 were included in a common registry.

It is presented a 48 year-old male patient with antecedent of a foreign body intake (a beer metallic top) 4 years ago, who rejected surgery at first previous a failed attempt of endoscopic extraction. Four years later he was admitted in the Thorax National Institute in an emergency, with acute respiratory failure and sepsis signs that were corrected quickly; later on after failed surgical attempts of trachea-esophageal fistula correction and extraction of the foreign body, the patient was sent to BJIG where the endoscopic extraction of the foreign body located in the trachea was carried out together with the correction of the trachea-esophageal fistula by means of implantation, in esophagus, of covered self-expanding prosthesis.

In this case we present a patient with chronic abdominal pain of a year of evolution, three months before being admitted to hospital the patient presented melaena and anaemia. Within the surgery antecedents it appears a caesarean 2 years before and a cholecystectomy a year before. In the endoscopy study a textiloma was observed coming up from the posterosior side of the antrum which, after its endoscopic removal, showed a gastro-duodenal fistula with a non-patent pylorus.

[Pilot test for Helicobacter pylori detection with ammonia breath test].

Background: In Argentina we have little access to the more sensitive and specific non-invasive diagnostic methods for the detection of Helicobacter pylori (HP), such as the urea breath test. The upper gastrointestinal videoendoscopy, with biopsy for histological analysis and rapid urease test remains as the usual method in our country, but the cost is high and the accessibility is also limited. For this reason we propose to develop a new fast, accurate, accessible and inexpensive method for measuring the concentration of expired NH in order to achieve a diagnosis of active infection.
