Guidelines of the Chilean EndocrinologySociety for the correct clinical use of bone densitometryOsteoporosis is a silent and frequent disease, which increases fracture risk. Approximately half of women and one of five men over 50 years old will suffer an osteoporotic fracture throughout their lives. Dual-energy x-ray absorptiometry (DXA) allows a real bone mineral density (BMD) measurement in different parts of the skeleton and is considered the "gold standard" for quantifying osteoporosis with high accuracy and precision. The Board of the Chilean Society of Endocrinology and Diabetes (SOCHED) required from the Bone Disease Study Group to develop a consensus about the "Correct use of bone densitometry in clinical practice in Chilean population". Therefore, we elaborated 25 questions which addressed key aspects about the indications for a DXA scan, and the details of how to perform and report this test. Since some of the evidence obtained was of low quality or inconclusive, we decided to create a multidisciplinary group of national experts in osteoporosis to develop a consensus in this subject. The group consisted of 22 physicians including endocrinologists, gynecologists, geriatricians, radiologists, rheumatologists and nuclear medicine specialists. Using the Delphi methodology to analyze previously agreed questions, we elaborated statements that were evaluated by the experts who expressed their degree of agreement. The final report of this consensus was approved by the SOCHED board.
Trabajar el teatro desde el aula es una propuesta que genera cambio y desarrolla conocimiento. Busca superar las dificultades en preguntas de nivel literal e inferencial para mejorar los resultados en las pruebas Saber. Se trabajó con 22 estudiantes del grado tercero del Colegio La Salle Ocaña, bajo la metodología investigación - acción de corte cualitativo, que permitió la práctica reflexiva docente-estudiante, el trabajo mediante juegos, cuentos, fábulas, leyendas y obra teatral, en los cuales se aplicaron talleres para desarrollar la comprensión lectora. Se observó motivación, diálogo, representación de personajes; se amplió el vocabulario, el manejo de espacio, la expresión verbal, la no verbal y la escritura de narraciones. Una estrategia que se sugiere aplicar desde los primeros años de escolaridad.
