Carney triad: A case report, characteristics and literature review of this rare entity.

Introduction And Importance: Carney triad is a rare entity of unknown etiology, characterized by the association of tumors with low incidence such as: gastric leiomyosarcoma, pulmonary chondroma and extra-adrenal paraganglioma. We show a case of Carney triad diagnosed in our center that has some different characteristics to the typical presentation of this patology, and a review of the literature.

Case Presentation: We present the case of a 47-year-old men who was admitted to our hospital for upper gastrointestinal bleeding and anemia.

[Significance of free perigastric fluid detected by echoendoscopy in patients with gastric cancer].

Objectives: To determine the diagnostic value of free perigastric fluid identified by echoendoscopy in patients with gastric cancer and to establish the factors related to the presence of peritoneal carcinomatosis in these patients.

Material And Methods: We retrospectively included 100 patients with a histological diagnosis of gastric adenocarcinoma referred for echoendoscopy. A positive result was defined as the echoendoscopic identification of free perigastric fluid.

[Serological diagnosis of atrophic gastritis with a combination of pepsinogen I and II, gastrin-17 and anti-Helicobacter pylori antibodies].

Objective: Noninvasive diagnosis of atrophic gastritis would help to identify individuals at increased risk of gastric carcinoma. In the present study, we evaluated the utility of a serological panel combining pepsinogen I and II, gastrin-17, and anti-Helicobacter pylori antibodies (Gastropanel) as a screening method for atrophic gastritis.

Patients And Methods: The serological panel was evaluated in 56 patients divided in two groups: group 1 consisted of 47 patients with uninvestigated dyspepsia and group 2 was composed of nine consecutive patients with gastric carcinoma.

[Stromal tumors of the jejunum and obscure gastrointestinal bleeding. Use of minimally invasive techniques in three cases].

Gastrointestinal bleeding is considered to be obscure when routine endoscopic techniques (esophagogastroscopy and colonoscopy) fail to identify the origin of the hemorrhage. These hemorrhages represent 5% of all gastrointestinal bleeding. Twenty-seven percent of these hemorrhages are due to small bowel disease and gastrointestinal stromal tumors (GIST) are a frequent cause, especially in middle-aged patients.
