Abstract: introduction: although the supine position created by dr. valdivia two decades ago to perform the procedure known as percutaneous nephrolitectomy (pnl) presents advantages against the prone position in some aspects concerning anesthesia and surgical ergonomy, its use has failed to spread widely among the urology community due to certain technical difficulties, a lower rate of calculi clearing and a higher rate of complications, in spite of the fact that the scarce comparative studies do not show enough data to support this opinion. the present study compares both positions considering the technical difficulties encountered, their effectiveness and their results and complications. material and methods: a series of 50 patients that underwent pcnl by prone position is compared retrospectively with another series of 54 patients that underwent consecutively pcnl by prone position. all procedures were performed under general anesthesia, the inferior calyx approach was the one used the most over the supracostal approach, and the sole tract over the multi-tract approach was predominant. dilatation of the nephrostomy tract was done, in most of the cases, with a high-pressure balloon catheter. the stone surface treated was 399.93±58.2 mm2 for the supine group, and 416.36±46.54 mm2 for the prone one (p=0.456). the management of the stones was carried out by ultrasonic or ballistic fragmentation, and a small group of patients underwent direct stone removal. results: as far as demographic parameters and operative variables such as number of tracts performed, calyx election, type of tract dilatation and kind of energy used for fragmentation, both groups were homogeneous. in 3 cases of each group there was a failure to access the kidney. the rate of failure was 6%, and 5.56%, for the supine and prone groups, respectively (p=0.716). average operating time was 74.55±25.54 and 91.82±24.82 minutes, respectively, p=0.123. a postoperative x-ray showed a stone-free rate of 76% for the su

Abstract: La posición del sol en la esfera celeste da origen a diferentes tiempos: el solar y el sideral. Debido al movimiento irregular del sol en su órbita aparente, a la variación de la oblicuidad de la elíptica y la no uniformidad del tiempo sideral, hay que introducir correcciones o la posición del sol para obtener un tiempo uniforme. Como consecuencia de lo anterior y en función de la latitud del lugar, la duración del día-luz es variable durante el a o. Por estar Colombia situada en la zona ecuatorial no se aprecian grandes diferencias en tiempo entre la duración del día-luz y la noche en el transcurso del a o: encontrándose 12h O8m como promedio del día-luz.

Revista signos , 2006, DOI: 10.4067/S0718-09342006000300002
Abstract: this paper provides evidence for the function of discourse markers in the expression of politeness and modality in the discourse of a therapeutic interview. the analysis is based on pragmatic theory, conversational analysis and politeness strategies, as facilitators of the social relations and of the interactants? expression roles in discourse (brown & levinson, 1987). the results show that the choice of one discourse marker or another is dependent on the tension between power and solidarity in the contextual situation, in agreement with the politeness strategies at work. this evidence supports that the control of conversational turns and the content of the interview are correlated with the initial context of the beginning of the interviewer?s turn, either in the professional?s medical-empathetic voice or educational-empathetic voice. these results contrast with a greater degree of overlapping functions and higher frequency of the discourse markers used by the interviewed patient?s informative voice, as well as by the professional?s educational-empathetic voice, which has an inducing, instructive and appealing function.
Cortesía verbal y modalidad: Los marcadores discursivos Politeness and modality: Discourse markers

Abstract: El trabajo muestra evidencia, a nivel del contexto de entrevista clínica a mujeres pacientes, que los marcadores discursivos están implicados en la marcación de las estrategias de cortesía verbal y de la modalidad del discurso. Los análisis realizados se enmarcan en lateoría de la pragmática, el análisis conversacional y las estrategias de cortesía, facilitadoras de las relaciones sociales y la expresión de los roles de los interactantes (Brown & Levinson,1987). Los resultados del análisis indican que la selección de uso de los marcadores discursivos depende de la tensión entre poder y solidaridad en la situación contextual, en concordancia con las estrategias de cortesía adoptadas. De este modo, la evidencia demuestra que el control de turnos y contenido de la entrevista está relacionado con el contexto de inicio de turno dela entrevistadora en sus voces médico-empática y educativo-empática, en contraste con una mayor multifuncionalidad y frecuencia de uso de los marcadores en el desarrollo del turno en la función de la voz informativa de la paciente y en la función inductiva, instructiva y apelativa de la voz educativo-empática de la profesional. This paper provides evidence for the function of discourse markers in the expression of politeness and modality in the discourse of a therapeutic interview.

The results show that the choice of one discourse marker or another is dependent on the tension between power and solidarity in the contextual situation, in agreement with the politeness strategies at work. This evidence supports that the control of conversational turns and the content of the interview are correlated with the initial context of the beginning of the interviewer’s turn, either in the professional’s medical-empathetic voice or educational-empathetic voice.

Abstract: Los sistemas de información integrados y compartidos permiten obtener un elevado nivel de información sobre los procesos, costes y resultados, y reducir considerablemente los errores de medicación. La prescripción electrónica asistida, en el área de nutrición parenteral total, integrado con otras bases de datos del hospital y con el sistema de gestión de medicamentos del hospital, es una herramienta que permite aumentar la seguridad del paciente (disminuyendo los errores de medicación), mejorar la calidad de la asistencia, mejorar los sistemas de información y la gestión de la misma y la eficiencia de los recursos empleados. En este trabajo se describe la implantación de un sistema de prescripción electrónica asistida aplicada a la nutrición parenteral en un hospital general, y la reingeniería de procesos llevado a cabo en el área de nutrición. Esta implantación se ha llevado a cabo por los facultativos médicos del servicio de Nutrición y Dietética y por farmacéuticos del Servicio de Farmacia del Hospital Ramón y Cajal utilizando para ello el programa informático "Nutriwin". Durante dos meses antes y después de su implantación, se ha realizado un seguimiento del tiempo empleado en el circuito prescripción-validación-elaboración-dispensación de las nutriciones parenterales. Tras la implantación las órdenes de tratamiento llegan, en promedio, 1 h 15 minutos antes al Servicio de Farmacia; al evitarse la trascripción se produce, además de la disminución de errores potenciales, un ahorro de 3 min/ nutrición en los cálculos a realizar; la elaboración de las nutriciones puede comenzarse como promedio 1h 20 minutos antes que si se realizara la prescripción manual. Así mismo los prescriptores pueden conocer en tiempo real el perfil nutricional de cada paciente en el episodio en curso así como su histórico. La prescripción electrónica de las órdenes de tratamiento en éste área ha supuesto para nuestro hospital una optimización de los recursos empleados, una disminución de los errores potenciales que se pueden producir, una mejora en la gestión de consumos, y un aumento en la calidad de todo el proceso. Integrated and shared information systems allow obtaining a high degree of information about processes, costs and outcomes, and considerably reducing prescription errors. Assisted electronic prescription, in the setting of total parenteral nutrition, integrated with other hospital databases and with the hospital drugs management system, is a tool that allows increasing patient' safety (by reducing prescription errors), improving quality assistance, improving informa
An Ethical Approach to the Concept of Toleration: Understanding Tolerance as a Political Virtue  [PDF]

Open Journal of Philosophy (OJPP) , 2014, DOI: 10.4236/ojpp.2014.44059
Abstract: The concept of toleration is commonly argued in political discourses and debates, when people refer to diversity and pluralism, as a form of respect and understanding. However, this does not represent an improvement at the moment of dealing with issues where a variety of values, conceptions and beliefs arises. In addition, even though when the idea of toleration was developed during Enlightenment, nowadays it seems to lead to a misconception of the term, following a connotation of a passive indifference about diversity. Due to this, the main objective of this text is to analyze the concept of toleration from an ethical perspective that allows thinking about it in terms of a political virtue needed to face the challenges of diversity inside society. In order to show this, the text presents an analysis of different conceptions of the term, in order to highlight the positive notion of toleration; after that, the text moves on, reviewing the idea of toleration from a hermeneutical perspective, as a form to reinforce the positive characteristics of the term, and path to solve the query between tolerance and intolerance. Finally, as a conclusion, it underlines that understanding the concept of toleration from an ethical perspective implies a praxis develop in daily circumstances.
