    Prevalence of the angiotensin I converting enzyme insertion deletion polymorphism, plasma angiotensin converting enzyme activity, and left ventricular mass in a normotensive Chilean population
    (ELSEVIER SCIENCE INC, 1999) Jalil, JE; Piddo, AM; Cordova, S; Chamorro, G; Braun, S; Jalil, R; Vega, J; Jadue'P, L; Lavandero, S; Lastra, P
    The aim of this study was to estimate the prevalence of the different alleles of the angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism and associated plasma ACE activity, as well as cardiac echocardiographic structure, in a healthy Chilean population. We selected 117 healthy normotensive subjects (aged 45 to 60 years, middle socioeconomic status, nonobese, and nondiabetic) from a population-based study concerning the prevalence of risk factors for chronic diseases (Conjunto de Acciones Para la Reduccion Multifactorial de las Enfermedades no Transmisibles [CARMEN]),

    Renal failure secondary to effort rhabdomyolysis.: Report of three cases
    (2006) Vega, J; Gutiérrez, M; Goecke, H; Idiáquez, J
    Renal failure secondary to effort rhabdomyolysis is uncommon. We report three males age 28, 37 (military sportsmen) and 44 years (sedentary obese), with this condition. Episodes occurred after a training session to run a triathlon, during the course of a mini marathon and during a rescue attempt of a drowning person. All three subjects experienced intense muscle symptoms, hemoglubinuria, oliguria, rise of blood urea nitrogen and a significant rise in muscle enzymes. Creatinekinase reached a maximum of 41 times normal, aspartate aminotransferase a maximum 35 times normal and lactacte dehydrogenase a maximum of 11 times normal. There was a rapid elevation of serum creatinine, reaching values of 6.6 and 9.8 mg/dl on the third day after the physical effort. This parameter had a disproportionate elevation in relation to urea nitrogen, in two subjects. All subjects were managed with saline hydration, sodium bicarbonate and furosemide. Only one required hemodialysis for two days. All normalized their renal function 18 to 48 days after the physical exertion. No subject had other predisposing conditions for acute renal failure (Rev Med Chile 2006; 134: 211-16).
