A study of seroprevalence of Helicobacter pylori determined by ELISA IgG, was conducted in 83 consecutive healthy children. The majority of the children (55%) had the bacterium. Seropositivity was demonstrated in 55% of the age group 0-5 years old, in 47% of 6-10, and in 67%, of the group 11 to 15. Of the children without sanitary inside their homes 86% were seropositive, versus 47% of the children with sanitary in their homes

Displasia severa en el esófago de Barrett / Severe dysplasia in Barrett's esophagus

Two patients with Barret's esophagus developed severe dysplasia diagnosed during endoscopic surveillance. Both patients underwent esophagectomy. The surgical specimen revealed adenocarcinoma in situ in the first patient and invasive adenocarcinoma to the submucosa in the second one. The life expectancy in these patients is at least 75% at 5 years, much better than the 5% five year survival of the patients diagnosed when they present with dysphagia. The natural history, pathogenesis, diagnosis, treatment and prevention are discussed

Unidad diagnóstica y terapéutica de la colangiopancreatografía retrógrada endoscópica (CPRE) en pacientes con diagnóstico de colédocolitiasis y sus complicaciones / The diagnostic and therapeutic unity of endoscopic retrograde cholangiopancreatography in patients with a diagnosis of choledocholithiasis and its complications

Reviewing the records of 60 patients admitted with clinical diagnosis of common duct stone, we demonstrated that the symptoms and the biochemical liver tests were predictive of choledocholithiasis only 50% of the time. The sensitivity for the ultrasound was 42%. The ERCP diagnosed pancreatic or biliary pathology in over 90% of the patients. Through endoscopic sphincterotomy, the ERCP prevented the surgical exploration of the common bile duct in 93% of the patients, and did not aggravate the clinical picture in the group with acute pancreatitis. The sequence of ERCP--laparoscopic cholecystectomy decreased the hospital days and has emerged as the treatment of choice for the patients with cholelithiasis and suspected common duct stone
