[Popular notions regarding "dengue" and "rompehuesos", 2 models of the disease in Colombia].

OBJECTIVE: To deliver, through children, educational messages to families in Neiva, the capital city of the department of Huila, in Colombia. METHODS: An educational project was developed to include, in schoolchildren's natural sciences and environmental education curriculum, basic education on dengue, its vector, and its control. Through surveys and Likert scales, the knowledge and attitudes in the schoolchildren's homes were determined. This was complemented with open-ended interviews that reflected cultural aspects in the area of health and how dengue disease is a part of people's lives. Before and after the intervention, larval infestation indices were determined for the schoolchildren's homes. RESULTS: A cultural pattern was found for the disease that differentiated between rompehuesos (breakbone fever) and "dengue". Rompehuesos corresponds, in popular terms, to classical dengue, a disease that can be dealt with using family and community resources. Institutional medicine, by means of its health agencies and health workers, as well as the communications media, has managed to superimpose another model: that which is associated with dengue hemorrhagic fever. DISCUSSION: Alternatives are considered for prevention efforts that would be sufficient for the conditions in which the vector's cycle occurs in Neiva. Also presented are the community's disease model and the survey results. Together, these elements can guide the formulation and development of educational efforts.

[A low-level stress test, in the early phase of myocardial infarction and its correlation with coronary angiography].

In a prospective 24-month trial at the Instituto Nacional de Cardiologia, 56 patients were studied. All patients had acute myocardial infarction (AMI), diagnosed by clinical, electrocardiographic and enzymatic means. They were studied in two groups: Group A with single localized AMI (n = 30) and Group B with AMI at two locations (n = 26); a resting electrocardiogram (EKG) was analyzed in each case and a low level stress test was performed within the 2nd and 3rd postinfarction weeks; coronary angiography was done between the 8th and 9th postinfarction weeks. In Group A the low level stress test (LLST) was positive for ischemia at a distance from the infarction site in 21, and eighteen of them had multi-vessel injuries (MVI); in 9 the LLST was negative; of these 7 had single-vessel injury; only the remaining 2 had MVI (p less than 0.001) with 90% sensitivity and 78% specificity. In Group B there was no significant relationship between LLST and coronary angiography (64% sensitivity, and 62% specificity). Relating the ischemic change at a distance in the resting EKG with coronary angiography, we found 75% sensitivity and 55% specificity in Group A. In Group B, sensitivity and specificity were even lower. We conclude that LLST in the early postinfarction phase in Group A is a safe and reliable method to suspect MVI, allowing the early identification of patients with lesions that could be treated by surgical means.
