[Multicenter study of Helicobacter pylori infection prevalence in patients with chronic gastroduodenal disease. Various epidemiologic features]. / Estudio multicéntrico de prevalencia de infección por Helicobacter Pylori en pacientes con patología gastroduodenal crónica. Algunos aspectos epidemiológicos.

The aim of this study was to establish the prevalence of H. Pylori infection in patients with chronic gastroduodenal pathology, who were treated in the gastroenterology units of four hospitals located in the Federal Capital and its neighbouring areas. 398 patients were studied by means of clinical assessment and epidemiology data. Upper endoscopy was carried out two biopsies were taken of the gastric antrum for a quick ureasa test and histological assessment of the H. pylori state by means of giemsa's stain. The prevalence of infection on the total of the studied population was 75.6%. In patients with gastric ulcer was 70%; in patients with duodenal ulcer it was 77.2% and 78.5% in patients with chronic gastritis. The prevalence of H. Pylori infection on the population according to age groups was: 61.54% in patients between 21 and 40 years; 76.14% in patients between 41 and 60 years, and 68.22% in patients over 60 year. We have tried to obtain a correlation between the prevalence of the infection and some sanitary characteristic (Running water and sewers) on the studied population. It was seen that 225 patients who lived in dwellings with running water and sewers showed a prevalence of infection of 69.34% and in 129 patients who did not have running water or sewer the rate of prevalence of infection was 83.72; a difference which was statistically significant, (with P < 0.01) for the patients who lived in poor sanitary conditions. These data may be important when the design of therapeutic schemes for the eradication of the bacteria is made.

El objetivo de este trabajo fue establecer la prevalencia de infección por H. Pylori en pacientes con patología gastroduodenal crónica, atendidos en las unidades de gastroenterología de cuatro hospitales de Capital Federal y conurbano. Se estudiaron 398 pacientes con evaluación clínica y datos epidemiológicos, se efectuó endoscopía alta con toma de dos biopsias de antro gástrico para test rápido con ureasa y evaluación histológica, con coloración de giemsa, del estado de infección con H. Pylori. La prevalencia de infección en la población total estudiada fue de 75,6 por ciento. En los pacientes con úlcera gástrica la tasa de prevalencia de infección por H.P. fue 70 por ciento en úlcera duodenal 77,2 por ciento y en gastritis crónica fue 78,5 por ciento. La prevalencia de infección por H.P. en la población según grupos etarios para pacientes menores de 20 años fue 61,54 por ciento; entre 21 y 40 años: 80,39 por ciento; entre 41 y 60 años 76,41 por ciento y en mayores de 60 años fue 68,22 por ciento. se ha intentado obtener de una correlación entre prevalencia de la infección y algunas características sanitarias (agua corriente y cloacas) de la población estudiada. Se observó ue 225 pacientes que residen en viviendas con agua corriente y cloacas, tuvieron una prevalencia de infección de 69,345 y en 129 pacientes sin agua corriente ni cloacas se observó una tasa de prevalencia de infección de 83,72 por ciento una diferencia estadísticamente significativa con un p< 0,01 para los pacientes con pobres condicones sanitarias. Estos datos puedem ser importantes cuando se efectua el diseño de los esquemas terapéuticos de erradicación de la bacteria.

[Gastric cancer. 11 years' experience in 8,304 endoscopic studies performed]. / Cáncer gástrico. 11 años de experiencia sobre 8.304 estudios endoscópicos realizados.

8.304 patients have been examined endoscopically in a period of time of eleven years. We found 412 with gastric cancer, a 4.96% of the total research. In 1970 we had the upper point with 8.71% and the lower point with 3.14%, in 1980. The 89.56% were advanced gastric cancer and the 1.95% were early gastric cancer. According to Borrmann classification, from advanced gastric cancer, 18 were mixed types. Because of technics reasons or lost controls, in 8.49% of the cases the real origin, could not be confirmed. In our hospital, between 1970 and 1980. We have found a diminution of the incidence of cancer.

[Value of endoscopy in the diagnosis of upper digestive tract hemorrhage]. / Valor de la endoscopía en el diagnóstico de las hemorrhagias digestivas altas.

In 11 years experience (67-78) we studied the importance of endoscopy in HDA. Were carried out 8300 esophagogastroduodenal endoscopies of which 2837 were HDA. The main reasons to follow these studies were: 1) Diagnostic of the HDA location; 2) Diagnostic of type of injury; 3) Injury intensity. Referring to the findings 30% were duodenal ulcer; 27% hemorrhagic gastritis; 17% gastric ulcer and 10% were due to VE. From the remaining 10% the most frequent were the esophagitis and gastric cancer. It is most important to show that aspiring added to alcohol in the most common cause of hemorrhagic gastritis. We have to point out that in 42 endoscopies performed in Intensive Care Service 10 of them were due to non-digestive causes. Through this method of diagnosis the Endoscopist has an important role to play in defining the prognosis and conduct to be followed.
