Acute renal failure (ARF) is a clinic syndrome characterized by decline in renal function occurring over a short time period. Is a relatively common complication in hospitalized critically ill patients and is associated with high morbidity and mortality. ARF has often a multi-factorial etiology syndrome usually approached diagnostically as pre-renal, post-renal, or intrinsic ARF. Most intrinsic ARF is caused by ischemia or nephrotoxins and is classically associated with acute tubular necrosis (ATN). High mortality is associated with severity of ARF, age more than 60 years old and presence of pulmonar and cardiovascular complications. Most patients who survive an episode of ARF recover sufficient renal function; however, 50% have subclinical functional defects in renal function or scarring on renal biopsy. ARF is irreversible in approximately 5% of patients, usually as a consequenc...

Objective: To assess the consistency of the results of the National Medicine Exam (NME) in Peru for years 2008 and 2009.   Material and method: We examined consistency between general and partial results obtained by the different public and private medical schools from Lima or other cities using official published data regarding the results of NME in Peru for years 2008 and 2009. These results were analyzed taking into account both numerical scores and ordinal variables (when considering the order on the basis of partial results that resulted in the final rank order). Statistical significance was established in p<0.05.   Results: The correlation was good (r>0.90) between the order considering the overall score and rank order in the two periods studied, but the best result was obtained in 2008. The correlation between the rank order obtained in both years wa...
