Monologue or Intercultural Dialogue Between Medical Systems? An Educational Challenge for Medical Sciences

Each medical cultural system constructs knowledge about health through specialization or interculturalism. The knowledge constructed through interculturalism has sought, mainly, to adapt the delivery of health care services to the users’ cultural referents. This emphasis has overlooked the opportunities embedded in the establishment of intercultural relationships between medical systems based on dialogue, especially in regard to the adjustment of the disciplinary boundaries of medical cultural systems that would allow the construction of new knowledge on health. This absence of dialogue has been determined by epistemological barriers inherent to every system as well as by social domination. This article presents some concepts related to cognition processes which encourage the reflection on the possibilities to overcome such barriers so that the health sciences may contribute to the effective implementation of the World Health Organization and the State’s recommendations on the matter.

Good practice : communication skills in English for the medical practitioner. Teacher's book.

Recurso para médicos y estudiantes de medicina que necesitan el inglés para comunicarse con los pacientes. Se centra en las habilidades del lenguaje y la comunicación que los doctores necesitan para hacer las consultas más eficaces con los cinco elementos para una buena comunicación: comunicación verbal, escucha activa, administración de voz, comunicación no verbal y conciencia cultural. Enseña a los estudiantes a manejar un repertorio de situaciones como pueden ser historia del paciente, malas noticias de última hora, tratar diferentes tipos de pacientes. El libro del profesor ofrece las herramientas esenciales y los antecedentes necesarios para potenciar en el aula el inglés para médicos. En los clips de DVD se hace una réplica de escenarios clínicos simulados que es probable que encuentren en su labor profesional.

Medical image registration based on random line sampling

One of the key aspects in 3D-image registration is the computation of the joint intensity histogram. We propose a new approach to compute this histogram using uniformly distributed random lines to sample stochastically the overlapping volume between two 3D-images. The intensity values are captured from the lines at evenly spaced positions, taking an initial random offset different for each line. This method provides us with an accurate, robust and fast mutual information-based registration. The interpolation effects are drastically reduced, due to the stochastic nature of the line generation, and the alignment process is also accelerated. The results obtained show a better performance of the introduced method than the classic computation of the joint histogram

Incongruence between test statistics and P values in medical papers

Given an observed test statistic and its degrees of freedom, one may compute the observed P value with most statistical packages. It is unknown to what extent test statistics and P values are congruent in published medical papers. Methods: We checked the congruence of statistical results reported in all the papers of volumes 409–412 of Nature (2001) and a random sample of 63 results from volumes 322–323 of BMJ (2001). We also tested whether the frequencies of the last digit of a sample of 610 test statistics deviated from a uniform distribution (i.e., equally probable digits).Results: 11.6% (21 of 181) and 11.1% (7 of 63) of the statistical results published in Nature and BMJ respectively during 2001 were incongruent, probably mostly due to rounding, transcription, or type-setting errors. At least one such error appeared in 38% and 25% of the papers of Nature and BMJ, respectively. In 12% of the cases, the significance level might change one or more orders of magnitude. The frequencies of the last digit of statistics deviated from the uniform distribution and suggested digit preference in rounding and reporting.Conclusions: this incongruence of test statistics and P values is another example that statistical practice is generally poor, even in the most renowned scientific journals, and that quality of papers should be more controlled and valued

New medical registration and segmentation techniques using information-theoretic tools

El processament d'imatges mèdiques és una important àrea de recerca. El desenvolupament de noves tècniques que assisteixin i millorin la interpretació visual de les imatges de manera ràpida i precisa és fonamental en entorns clínics reals. La majoria de contribucions d'aquesta tesi són basades en Teoria de la Informació. Aquesta teoria tracta de la transmissió, l'emmagatzemament i el processament d'informació i és usada en camps tals com física, informàtica, matemàtica, estadística, biologia, gràfics per computador, etc. En aquesta tesi, es presenten nombroses eines basades en la Teoria de la Informació que milloren els mètodes existents en l'àrea del processament d'imatges, en particular en els camps del registre i la segmentació d'imatges. Finalment es presenten dues aplicacions especialitzades per l'assessorament mèdic que han estat desenvolupades en el marc d'aquesta tesi.
