To the Editor.— Two recent reviews in Pediatrics1,2 provide much interesting information on the effect of home visits on the health of women and children. However, I was disappointed not to find in either article more than token reference to the cost of the programs reviewed. In this day of increasingly scarce health care resources, we no longer have the luxury of evaluating programs such as these without detailed consideration of their cost-benefit ratio.

AbstractThe authors review the main concepts regarding the importance of cleaning/disinfection of ultrasonography probes, aiming a better comprehension by practitioners and thus enabling strategies to establish a safe practice without compromising the quality of the examination and the operator productivity. In the context of biosafety, it is imperative to assume that contact with blood or body fluids represents a potential source of infection. Thus, in order to implement cleaning/disinfection practice, it is necessary to understand the principles of infection control, to consider the cost/benefit ratio of the measures to be implemented, and most importantly, to comprehend that such measures will not only benefit the health professional and the patient, but the society as a whole.

AbstractThe costs and benefits of vaccinating troops on United Nations tours in Yugoslavia against hepatitis A were compared. The marginal cost of one case of hepatitis A avoided by vaccination was calculated and compared with the marginal cost of achieving the same outcome by passive immunization. The cost-benefit ratio (medium estimate) for troops at low risk of contracting hepatitis A was 0.01 and for those at high risk was 0.03.Vaccinating troops against hepatitis A for a single deployment appears to be an inefficient procedure, especially in troops at low risk. However, in professional troops from countries of low hepatitis A endemicity who are likely to be involved in several operational deployments, vaccination becomes more efficient the more times the same troops are deployed.

The Cost

The present study makes a comparative analysis of the cost-benefit ratio between Conventional Concrete (CC) and High Performance Concrete (CAD). To obtain the consumption rates of concrete, steel and shape of each case, two studies of the same structure were carried out, changing only one variable: the characteristic strength of concrete to compression (fck). In the first case, the 25 Megapascal fck (MPa) representing the CC was applied, and in the second case, 50 MPa fck corresponding to the CAD. For analysis of the structural elements, the Cypecad Software was used. It was found that one of the initial hypotheses, that the consumption of concrete, steel and form would decrease with the use of CAD, was confirmed. The second hypothesis, that the CAD would be more financially advantageous than the CC, was not confirmed, but factors that may have led to this non-confirmation were pointed out.
