Objective: To know the relationship between the values of the pressure blood and myocardial ischemia in critical patients older than 65 years who were admitted in emergency to a hospital of medium complexity of social security. Material and methods: Cross-sectional, retrospective, explanatory and observational study. Sampling not probabilistic in 192 critical patients (priority I and II), older than 65 years, which were admitted by emergency to the Hospital II Vitarte EsSalud, since January 2014 to October 2015, with at least one determination of Troponin I at admission in emergency. Ranges of Spearman correlation Test and Test of binary logistic were used to calculate the risk of occurrence of myocardial ischemia in relation to systolic or diastolic blood pressure values. Results: There was a negative correlation between the value of the diastolic blood pressure with the presence of ischemia myocardial (Rho of Spearman = - 0,155; p = 0,032), statistically significant. It was risk found risk of ischemia myocardial in patients with diastolic hypotension OR: 2,545; IC: 1,051-6,163; NC: 95%; and with normal OR diastolic pressure values: 3,320; IC: 1,479-7,452; NC: 95%. Conclusions: Changes in blood pressure are usually presented in critically ill patients, having to take into account the assessment of cardiac enzymes, when diastolic blood pressure values are below normal values. Although the results are clearly predictive, they can't be generalized given our non-random sample, and restricted to over 65 years old. [ABSTRACT FROM AUTHOR]

Objective: To know if there was an increase in acute appendicitis cases treated in summer and spring among 2005-2014 in Grau Emergency Hospital in Lima. Material and Methods: Observational, cross-sectional and retrospective study. Non-probabilistic sampling, sample size of 6,917 operated on for acute appendicitis during 2005-2014 in the Grau Emergency Hospital in Lima. We used a form for data collection from medical records to develop a database. Analysis of variance test was applied to appendectomies numbers and correlation between temperature and number of appendicitis. Results: The minimum and maximum age was 14 and 93 years old. 52.6% (3,639) of the cases were female. January was the highest monthly number of appendectomies, with 648; 634 in March and 616 in February. The analysis of variance obtained a p value = 0.24, there was no significant difference among the seasons of the year. There was a partial correlation between monthly temperature and number of appendectomies. Conclusions: There is a seasonal pattern with increase in the frequency of acute appendicitis during summer and spring, and a decline in autumn and winter. The increase in cases of acute appendicitis is 3.32% and 3.75% in summer compared to autumn and winter, with no significant statistical difference among the four seasons of the year.
