- ItemAnálisis crítico de un artículo: ¿Es confiable la medición de adenosin deaminasa (ADA) para el diagnóstico de derrame pleural tuberculoso?(2009) Herrera Riquelme, Cristian Alberto; Aravena León, Carlos AndrésBackground: Conventional tests are not always helpful in making a diagnosis of tuberculous pleurisy. Many studies have investigated the usefulness of adenosine deaminase (ADA) in pleural fluid for the early diagnosis of tuberculous pleuresy. We conducted a metaanalysis to determine the accuracy of ADA measurements in the diagnosis of tuberculous pleurisy. Methods: After a systematic review of English language studies, sensitivity, specificity, and other measures of accuracy of ADA concentration in the diagnosis of pleural effusion were pooled using random effects models. Summary receiver operating characteristic curves were used to summarize overall test performance. Results: Sixty-three studies met our inclusion criteria. The summary estimates for ADA in the diagnosis of tuberculous pleurisy in the studies included were sensitivity 0.92 (95% confidence interval 0.90-0.93), specificity 0.90 (95% confidence interval 0.89-0.91), positive likelihood ratio 9.03 (95% confidence interval 7.19-11.35), negative likelihood ratio 0.10 (95% confidence interval 0.07-0.14), and diagnostic odds ratio 110.08 (95% confidence interval 69.96-173.20). Conclusions: ADA determination is a relative sensitive and specific test for the diagnosis of tuberculous pleurisy. Measurement of ADA in pleural effusion is thus likely to be a useful diagnostic tool for tuberculous plerisy. The results of ADA assays should be interpreted in parallel with clinical findings and the results of conventional tests

- ItemEvaluación del ambiente educacional pre-clínico en seis Escuelas de Medicina en Chile(2010) Herrera Riquelme, Cristian Alberto; Pacheco, Jorge; Rosso, Francisca; Cisterna, Cynthia; Aichele, Daniela; Becker, Susana; Padilla Pérez, Oslando; Riquelme Pérez, ArnoldoBackground: The Dundee Ready Education Environment Measure (DREEM) is the most valid and reliable instrument to measure the educational environment (EE) in undergraduate medical education. Aim: To evaluate the EE perceived by undergraduate medical students in Chile, using a Spanish version of the DREEM questionnaire. Material and Methods: The DREEM was applied during 2008 in third, fourth and fifth undergraduate years of six medical schools. The individual results were calculated and means of both global and individual domain scores of the DREEM were compared, by year, gender and between different Schools.Results: One thousand ninety two students (77% of the total universe of students), answered the questionnaire. The mean score of the six Schools was 113.9. The domains of Perception of Learning and Social Self-Perception obtained the lower scores, with a global outcome indicating a more positive than negative EE. Two schools obtained mean scores of 128.32 and 126.87, that were significantly higher than the global scores obtained by other schools. No relevant differences by years or gender were observed. Conclusions: There is a significant variability between the six schools evaluated and two of these obtained significantly better scores than the rest. The identified positive and negative areas will orient the actions to improve the EE for undergraduate medical students
