Decrease in prevalence of peptic ulcer and gastric adenocarcinoma at the Policlínico Peruano Japones, Lima, Peru, between the years 1985 and 2002. Analysis of 31,446 patients.

Aim: To determine the prevalence of peptic ulcer and gastric adenocarcinoma in a population of middle and high socio-economic status in Lima, Peru, between 1985 and 2002.

Material And Methods: The prevalence of gastroduodenal ulcer and gastric adenocarcinoma was determined after studying by esophagogastroduodenoscopy 31,446 patients at the Policlínico Peruano Japonds (PPJ) between 1985 and 2002. All patients had chronic upper gastrointestinal symptoms and had endoscopically proven diagnosis of active peptic ulcer or histological diagnosis of gastric adenocarcinoma.

[Comparison of the prevalence of Helicobacter pylori stomach infection in Peruvian and Japanese population].

Objective: To compare the prevalence of Helicobacter pylori infection in native Peruvians and Japaneses residing in Peru.

Methods: Prospective study carried out at "Policlinico Peruano-Japonés" (Lima-Perú). We included Peruvians and Japaneses residing in Peru with chronic symptoms of the upper gastrointestinal tract.

Helicobacter pylori-associated chronic atrophic gastritis involving the gastric body and severe disease by Vibrio cholerae.

Evidence has associated chronic infection by Helicobacter pylori with chronic gastritis, low gastric acid production and an increased risk of life-threatening cholera. However, the relationship of specific patterns of histological damage in the gastric mucosa associated with H. pylori infection and the occurrence of cholera has not been described.

Thyroid hormone levels improve the prediction of mortality among patients admitted to the intensive care unit.

Objective: As hormones are strongly associated with mortality in critically ill patients, we investigated whether mortality prediction based on the Acute Physiology and Chronic Health Evaluation (APACHE) is improved by combining this score with hormone measurements.

Design And Setting: Intensive care units in three hospitals.

Patients And Participants: 113 patients admitted to.

[Omeprazole, amoxicillin and clarithromycin in the treatment of helicobacterpylori, in 7 and 10-day regimens].

Aim: The most accepted treatment for infection by Helicobacter pylori is the proton pump inhibitor based therapy with two antibiotics. However, there is no consensus regarding the duration. The purpose here was to compare eradication percentages in the omeprazole+amoxicillin+clarithromycin regimen administered during 7 days versus 10 days and confront the results with a previous 14-day* experience in Peru.

[Changes in the prevalence of H. pylori in Perú; during the 1985-2002 period in medium and upper socio-economic strata].

Introduction: In the developed countries, the prevalence of infection by H. Pylori among patients with active chronic gastritis (ACG) and peptic ulcer is diminishing. In developing countries, as far as it is known, neither a time variation of this infection nor a related epidemiological phenomena have been reported.

[CONTRIBUTION STUDY TO THE EPIDEMIOLOGY OF HELICOBACTERPYLORI IN PERU: ANALYSIS OF 3005 CASES].

Compiling our observations from the last 15 years in regard to the epidemiology of Helicobacter pylori in Perú, we have analized 3005 cases. Studying and comparing the rates of infection among japanese inmigrants living in Perú for more than 10 years, niseis, japanese visitors and peruvians, we found similar rates. According to these results it seems that at least in japaneses there is not any genetic predisposition to acquire the infection.

[HELICOBACTER PYLORI, CHRONIC GASTRITIS, GASTRIC ANDDUODENAL ULCER: STUDY OF 1638 PATIENTS].

We anaylize in patients from high socio economic level the histologic findings of biopsies from the gastric mucosa taken endoscopically. Patients with upper gastrointestinal symptoms were examined with esophagogastroduodenoscopy. In the histologic study we considered: presence of Helicobacter pylori, mucinous damage, displasia, atrophy and intestinal metaplasia.

[CLINICAL CHARACTERISTICS IN COLON CANCER E. REBAGLIATI MARTINS HOSPITAL 1995-1999].

In Peru, the Colorectal Cancer affects people of both sexes, making it necessary to know the clinical characteristics of this disease, in order to improve its diagnosis. With this purpose it was set a retrospective and descriptive study at E. Rebaglitati Martins Hospital.
