ABSTRACT

El objetivo de este estudio es desarrollar y validar una pauta para la evaluación del proceso de enseñanza clínica en radiología; Medicina Universidad Católica, Radiología 32 ítems (MEDUC-RX32). Se utilizó metodología mixta para el desarrollo del instrumento: dos entrevistas grupales (residentes y docentes) y una individual a un jefe de programa de radiología. Utilizando técnica Delfi modificada para lograr acuerdo, un panel de validez nacional evaluó la importancia de cada ítem. El panel Delfi refinó el instrumento de 88 a 32 ítems luego de dos rondas. La pauta final fue piloteada en 55 residentes del programa. El instrumento definitivo presenta alta confiabilidad (coeficiente alfa de Cronbach de 0,957). El promedio de las evaluaciones del desempeño de los docentes fue de 6,23 mas menos 0,8 (escala Likert 0 a 7) constituyéndose en una pauta válida y confiable para la evaluación de docentes de programas de la especialidad de radiología en países de habla hispana.


The objective of this study is to develop and validate a guideline for the evaluation of the clinical teaching process in radiology; Catholic University Medical School, Radiology 32 items (MEDUC-RX32). A mixed methodology was used for the development of the questionnaire; two interview groups (residents and faculty) and one individual to a radiology program head. Using a modified Delphi technique to reach an agreement, a national validity panel assessed the importance of each item. The Delphi panel refined the questionnaire from 88 to 32 items after two rounds. The final guideline was perfomed in 55 residents of the program. The final instrument shows high reliability (Cronbach's alpha coefficient of 0.957). The average performance evaluations of teachers was 6.23 ± 0.8 (Likert scale 0 to 7) becoming a valid and reliable guideline for teacher evaluation of programs in the specialty of radiology, in Spanish speaking countries.

ABSTRACT

Background: 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.

ABSTRACT

Se presenta una técnica modificada de laparoscopia abierta, realizada en doscientos pacientes con indicación de laparoscopia o cirugía laparoscópica. No se presentaron complicaciones intraoperatorias o postoperatorias relacionadas con la técnica. Todas las pacientes fueron controladas una semana posterior a la cirugía, ninguna presentó infección o hernia. Las modificaciones a la técnica clásica de laparoscopia abierta descrita en el presente artículo, la transforman en un procedimiento simple y eficiente manteniendo la seguridad inherente a la técnica original
