[Macroscopic aspect and depth in early gastric cancer].

Depth of invasion in Early Gastric Cancer (E.G.C.) is very important to be evaluated. We reviewed 78 cases of E.G.C., in patients of our program that were operated on. We established the relationship among three macroscopic variables (localization, size and macroscopic shape) and depth of invasion. We realized that the lesions located in the fundus, though diagnosed less frequently, has more tendency to invade the submucosa (50%), in relation to other localizations. We did not find a significant statistic relation chi 2 = 3.76 P: .58 df:5 between size and invasion. The macroscopic types IIa + IIc and the E.G.C. type III have tendency to further invasion (58.8 and 66.67%). The polypoid lesions Type I and IIa are mostly intramucosal, so they could be treated endoscopically in high risk and old patients.

[Use of role-playing in child psychotherapy and psycho-pedagogy].

Spontaneous role-playing in children stands as a contribution in generating and in improving social behaviors. Spontaneous role-playing is a part of the child's maturing process. Its characteristics: it does not follow any logical pattern; it is frequently repeated; its emotional involvement is important, without ambivalence. Educational role-playing attempts to help the child in coping with a peculiar interpersonal situation. Therapeutical role-playing may be used in helping children suffering from a definite impairment of social skills--or from any psychological or medical problem. We report an example of the use of therapeutical role-playing in a group of diabetic children suffering from disorders in interpersonal relationships arisen at the time of the onset of their physical illness.

[Inflammatory response associated with Helicobacter pylori infection in gastric mucosa with intestinal metaplasia in a population in high risk for gastric cancer].

Intestinal Metaplasia (IM) and Helicobacter Pylori (HP) infection had been related to gastric carcinogenesis. With the intention to know the relationship among HP infection, IM and inflammatory response of the mucosa in an area of high prevalence of gastric cancer, we studied 800 persons that attended the Gastric Cancer Mass Survey, ongoing in the State Tachira, Venezuela, since 1981. Out of these subjects, 259 had histology diagnosis of IM (32.4%) 52.1% were IM type Y, 19.3% type II and 22.8% type III (sulfomucin secretory). Histology demonstrated with Giemsa stain HP in 94.6% of the cases. Association between HP and inflammation response in gastric mucosa with IM, was statistically significant (p = 0.001). The are heavier bacteria overload in IM type I than in type III although it is not statistically significant. We ponder if gastric mucosa inflammation due to HP, conditions development of IM as a hostile way of the gastric environment to restrain bacterial growth. This phenomenon ally with other oncogeneous factors could induce to premalignant lesions and eventually gastric cancer.

[Early gastric cancer in the remnant stomach. Case report].

Patients with partial gastrectomy are a High risk group to develop gastric cancer. Risk is higher in remnant estomach after partial gastrectomy by malignancy than benign disease. We present a case of a male patient, 64 years old, who was admitted in our Hospital with Hypovolaemia. We found during Endoscopic examination early gastric Cancer IIc + III type in the site of anastomosis. Partial gastrectomy was performed in this patient by Duodenal ulcer 11 years ago.
