Therapeutic strategies in the prevention of acute renal failure.

The mechanisms involved and the potentially useful therapeutic strategies in the prevention of acute renal failure (ARF) are briefly reviewed. Factors mentioned are the role of calcium channel blockers, the antioxidant agents, heme oxygenase induction, and ferritin synthesis; and of substances with hemodynamic actions in ARF; such as endothelin, atrial natriuretic peptide, urodilatin, PAF antagonist, prostaglandins, diuretics, and dopamine. The loss of tubular epithelium polarity, the mechanisms involved in this process, and the usefulness of arginine-glycine-aspartic acid peptide and anti-ICAM antibodies in the prevention of tubular obstruction are also reviewed.

[Academic performance in the 1st year and its relationship with admission variables in medical schools. Comparative study].

Chilean universities employ a common admission scoring system for students, based on high school grades, mathematic and verbal academic aptitude tests, and specific biology and social sciences tests. Aiming to know the predictive values of these tests, the standardized scores obtained in the selection tests and academic performance of 1094 first year medical students, admitted in 1989 and 1990 to six universities, were analyzed. These students obtained high admission scores and their academic performance during the first year was low (mean grades ranged from 4.6 +/- 0.6 to 5.28 +/- 0.5 in different universities for a scale from 1 to 7). In all, except one university there was a correlation between admission scores and academic performance. Multiple regression analysis showed that admission scores explained a 13% of performance and that the parameters with better predictive value were high school grades, biology test and mathematics academic aptitude test. Verbal academic aptitude test did not have a predictive value.

[Hypothermia: a non renal indication for peritoneal dialysis].

Accidental hypothermia, a condition seldomly seen in Chile, is defined as a spontaneous core temperature reduction to less than 35 degrees C and is associated with great morbidity and mortality. We report a 16 years old female intoxicated with liquefied petroleum gas that was admitted in coma, hypothermic, with severe hemodynamic derangement, lactic acidosis, rhabdomyolysis and iliofemoral phlebothrombosis. Peritoneal dialysis with solutions at 27 degrees C was used as a quick and safe means to revert hypothermia and avoid its complications.
