Menetrier's disease. A diagnostic and therapeutic challenge.

We present a rare case of hypertrophic gastropathy associated with protein loss. A 35-year-old man was hospitalized for bowel habit changes, abdominal pain, generalized edema and symptomatic anemia. Pertinent laboratory findings included iron deficiency anemia (Hb 6.

[Faecal microbiota transplantation for Clostridioides difficile infection].

Clostridiodes difficile infection (CDi) is the most common cause of nosocomial diarrhea. Vancomycin, associated or not to metronidazol, is the treatment of choice. However, the rate of treatment failure has increased over the last years and fecal microbiota transplantation (FMT) has emerged as a therapeutic option.

Importance of a Rapid and Accurate Diagnosis in and Human T-Lymphotropic Virus 1 Co-infection: A Case Report and Review of the Literature.

and Human T-Lymphotropic Virus 1 (HTLV-1) share some endemic regions such as Japan, Jamaica, and South America and are mostly diagnosed elsewhere in immigrants from endemic areas. This co-infection has not been documented in Argentina although both pathogens are endemic in the Northwest. We present a case of and HTLV-1 co-infection with an initial presentation due to gastrointestinal symptoms which presented neither eosinophilia nor the presence of larvae in stool samples in a non-endemic area for these infections.

Development of an E-learning System for the Endoscopic Diagnosis of Early Gastric Cancer: An International Multicenter Randomized Controlled Trial.

Background: In many countries, gastric cancer is not diagnosed until an advanced stage. An Internet-based e-learning system to improve the ability of endoscopists to diagnose gastric cancer at an early stage was developed and was evaluated for its effectiveness.

Methods: The study was designed as a randomized controlled trial.

[Prolonged survival after local excision of a rectal leiomyosarcoma].

Leiomyosarcoma is a stromal tumor, originated from smooth muscle cells. The pathologic diagnosis represents a challenge in terms of differentiation from leiomyomas and gastrointestinal stromal tumors (GIST), defined by immunohistochemistry techniques. Its location in the rectum is extremely rare.

[Liver involvement in hereditary hemorrhagic telangiectasia].

Hereditary hemorrhagic telangiectasia (HHT) is a genetic disease with an autosomal dominant inheritance pattern, characterized by widespread telangiectases that can involve the skin, mucous membranes, lung, brain, gastrointestinal tract and/or liver. It has an estimated prevalence of 1 to 2 cases per 10,000. The prevalence of hepatic involvement in HHT had been estimated in 8% to 31% in retrospective studies but in more recent large prospective series the prevalence is higher, ranging between 41% and 78%.

[Bouveret syndrome: unusual cause of upper gastrointestinal bleeding].

A 85-year-old woman was seen for a 7 day history of abdominal pain and hematemesis the day of her admission. Endoscopic and radiologic tests revealed cholecystoduodenalfistula and stones (Bouveret syndrome).

Substance P in rectal mucosa of children with chronic constipation.

Substance P content was determined by radioimmunoassay in rectal mucosa of 17 children with idiopathic constipation and 9 with normal bowel movements who were used as controls. In children with chronic idiopathic constipation, rectal mucosa substance P levels were lower than levels in the control group: 47.6 +/- 11 vs.

EsophaCoil: long-term results in 81 patients.

Background: Cancer of the esophagus and gastric cardia cause progressive dysphagia. Half of patients are not amenable to surgical resection; of those who are, about 20% will suffer either from local recurrence or anastomotic strictures. Self-expandable metallic stents of diverse characteristics have been used in these clinical conditions.

[Adenoacanthoma of the upper esophagus. Report of a case].

We report a 72 year-old woman, with adenoacanthoma of the upper esophagus who was admitted in Hospital Israelita "EZRAH" in April of 1991. We performed a review of the literature on this rare tumour, that is the reason of presenting this case.

[Duodenogastric reflux: gammagraphic evaluation in gastric ulcer and chronic gastritis].

We intended to estimate D.G.R.
