This Consenso Nacional de Hipertensión Arterial Sistémica (National Consensus on Systemic Arterial Hypertension) brings together experiences and joint work of 79 specialists who have been in contact with the patient affected by systemic arterial hypertension. All concepts here presented were outlined on the basis of the real world practice of Mexican hypertensive population. The consensus was developed under strict methodological guidelines. The Delphi technique was applied in two rounds for the development of an appropriate statistical analysis of the concepts exposed by all the specialists, who posed key questions, later developed by the panel of experts of the Hospital de Cardiología, and specialists from the Centro Médico Nacional. Several angles of this illness are shown: detection, diagnosis, pathophysiology, classification, treatment and prevention. The evidence analysis was carried out using PRISMA method. More than 600 articles were reviewed, leaving only the most representative in the references. This document concludes with practical and useful recommendations for the three levels of health care of our country.

Background: Academic drop outs at the university level is a serious problem. At the School of Medicine of the UNAM, over 50% of students enrolled in their first year do not graduate. In order to solve this problem, the UNAM has tutoring and financial aids to help students. One area of enquiry is to analyze factors such as health status (physical and mental), lifestyle and environmental factors that may influence student's performance. The objective in the present study was to identify risk factors for overall health and establish a scholastic performance forecasting profile., Methods: Health variables included in the Examen Médico Automatizado (EMA) were correlated with the academic performance in a sample of students from two generations. Four groups were conformed and the variables that were analyzed included traditional academic program (TRAD), high academic demand and having a status as regular or irregular student., Results: 1,848 students were included in the study. The risk factors that characterized students in the TRAD program and had an irregular status were: signs of depression, anxiety, suicidal ideation and suicidal intent, prior pregnancy, poor interpersonal relationships, public school education, low income, parents with less than college education and long commutes from home to school. Students with an irregular status belonging to the high academic demand, reported the strongest protective factors against school failure., Conclusions: The EMA test identifies risk and protective factors that have an influence on student's academic performance. A forecasting failure profile was established among first year of students enrolled in the TRAD program. We suggest strategies that should be implemented and to continue studying cohorts of graduating students.

Liver biopsy was taken from 20 patients with chronic and acute alcoholism. The patients had been hospitalized for diverse reasons, had no clinical manifestations of alcoholic hepatitis nor cirrhosis, but did have abnormal liver function tests. The most common abnormal test results were low serum albumin, polyclonal gamma-globulin elevation, and S G O T and Alk P rise. In all patients one or more types of hepatic lesiones were found: steatosis (15), polynuclear and mononuclear infiltrates (15), and portal (7), interstitial (13), or centriobular (8) fibrosis. Two patients had cirrhosis. None had hepatic cell necrosis. These findings justify a motivated search for liver damage in patients with alcoholism who have slight alterations in liver function tests, even in the absence of clinical manifestations of liver disease.

Rotor's syndrome is a rare entity in our Country. We report here a case of this anomaly in a seventeen years old girl with jaundice from birth, normal biliary channels, elevated urinary coproporphyrins and retarded excretion of bromosulphalein with normal histology of the liver. The familiar study showed that the mother, but not the brothers, had a similar defect in excretion of bromosulphalein.
