Efecto de la actividad física en la calidad de vida de una población adulto mayor de Santiago / Effect of physical activity on quality of life of an elderly population of Santiago

Introduction: Aging involves the loss of functional reserve with alteration of multiple systems. This influences the deterioration of various aspects of health and quality of life. To improve these aspects there are different types of interventions in which physical activity has a prominent role. Objective: To evaluate the effectiveness of one type of physical activity in improving the quality of life of an elderly population of the community. Subjects and methods: We recruited 71 subjects aged 60 years attending a club of elderly. Were randomized into 2 groups (intervention and control) by a blinded observer. The intervention was aerobic physical activity for 30 minutes and calisthenics exercises for heating and cooling, for 10 weeks and 3 times a week. We evaluated 8 dimensions of quality of life at the beginning and end of the intervention by the SF-36. Results: Both groups had similar values at baseline. The intervention group improved clinically (5 to 25 points) and statistically significant (p <0.05) in the 8 dimensions of quality of life. The control group showed a modest improvement in 3 items exploring psychosocial aspects of quality of life. Conclusion: The physical activity in the community is a therapeutic alternative economic, easy to implement, safe to apply and produces a great impact on improving the quality of life of the population over 60 years.

Epidemiología de las lesiones conjuntivales y su correlación clínico-patológica / Epidemiology of conjunctival lesions and clinical-pathological correlation

Se realizó una revisión de los 1166 casos de lesiones conjuntivales recibidos por el Laboratorio de Patología Ocular del Hospital Clínico de la Universidad de Chile entre los años 1968-2005. En base a ella se describen los distintos diagnósticos histopatológicos según su frecuencia, distribución por sexo, edad, localización y tiempo de evolución. La edad promedio para los casos fue de 36 años con un 51,5 por ciento de hombres afectados y un tiempo de evolución promedio de 68 meses. Las lesiones más frecuentes fueron las pigmentarias (44,2 por ciento), seguidas de las epiteliales (22,7 por ciento) y los cuadros infecciosos (10,9 por ciento). La localización más frecuente para todas las lesiones fue bulbar. Se estableció, además, una correlación entre los diagnósticos clínicos e histopatológicos, la cual resultó ser positiva en un 60,9 por ciento, siendo marcadamente superior para las lesiones pigmentarias e inferior para lesiones degenerativas, cuadros infecciosos y tumores clasificados como pre-malignos o malignos.

We made a retrospective review of 1166 cases of conjuntival lesions, accepted for its study at the Laboratory of Ocular Pathology, University of Chile, from 1968 to 2005. Based on this survey, different histopathologic diagnosis were described, characterized by its frequency, gender distribution, age, location and time of evolution. The average age was 36 years, with a 51,5 percent being male, and an average time of evolution of 68 months. Most frequent lesions were pigmented (44,2 percent), followed by epithelial (22, 7 percent), and infectious diseases (10,9 percent). The most frequent location was bulbar. A clinical - pathologic correlation was established, being positive in 60,9 percent of cases. It was noticeable superior for pigmented lesions, and inferior for degenerative lesions, infectious disease and tumors classified as pre malignants or malignants.
