Determina la prevalencia de dolor musculo - esquelético y asociación con nivel de riesgo ergonómico en los recicladores de residuos sólidos de la margen izquierda del río Rímac en el año 2010. Estudio observacional, transversal y con componente analítico, en 92 recicladores del total de la población objetivo. Se realiza observaciones con lista de chequeo PLIBEL y entrevistas con cuestionario nórdico de síntomas musculoesqueléticos, identificando las variables dolor, nivel de riesgo ergonómico, edad, sexo, índice de masa corporal, tiempo de trabajo y horas de trabajo a la semana.

Con el objetivo de conocer la relación entre los valores de la presión sanguínea e isquemia miocárdica en pacientes críticos mayores de 65 años que ingresaron a la Emergencia del Hospital II Vitarte EsSalud, se realizó un estudio transversal, retrospectivo, explicativo y observacional, con un muestreo no probabilístico en 192 pacientes críticos (prioridad I y II), mayores de 65 años, que fueron admitidos a la emergencia desde enero del 2014 a octubre del 2015, con al menos una determinación de troponina I al ingreso. Se utilizó la prueba de correlación de rangos de Spearman y prueba de regresión logística binaria para calcular el riesgo de ocurrencia de isquemia miocárdica con relación a los valores de tensión arterial sistólica o diastólica. Se encontró que los cambios de la presión sanguínea son de presentación habitual en pacientes gravemente enfermos, debiénd...

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 isc...

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...
