Urgencias urológicas tratadas por cirugía de mínimo acceso / Urologic emergencies treated by means of minimally invasive surgeryUrgencias urológicas tratadas por cirugía de mínimo acceso / Urologic emergencies treated by means of minimally invasive surgeryLa obstrucción y el éstasis urinario se encuentran entre los temas más importantes de la Urología de todos los tiempos por los efectos devastadores que producen sobre el riñón, incluyendo la atrofia hidronefrótica, las infecciones a repetición y la muerte, siendo el resultado final de múltiples enfermedades. La nefrostomía percutánea introducida por S. I. Seldinger en 1952 y el catéter doble J diseñado en 1978 por Finney facilita el drenaje de riñones obstruidos, mejoran la sintomatología y permiten el estudio y tratamiento definitivo en ocasiones de la causa. Se realizó un estudio prospectivo descriptivo durante el período comprendido entre el 1ro noviembre de 2003 a diciembre de 2008 en el servicio de Urología del Hospital General Docente Abel Santamaría Cuadrado en Pinar del Río. La muestra estuvo integrada por los pacientes que fueron intervenidos por cirugía de mínimo acceso endo-urológico (nefrostomía percutánea y colocación de stens doble J. encontrando como principales resultados, que la principal causa de asistencia a consulta fue por cólico nefrítico; se realizaron más nefrostomías percutáneas en las litiasis ureterales obstructivas en relación con la colocación de catéter doble JJ, en ambos procederes las complicaciones mediatas más frecuentes presentadas fueron las sepsis post-instrumentaciones, la estadía post-operatoria promedio fue de 72 horas.Palabras Clave: Acceso endourológico, nefrostomía percutánea/efectos adversos/método, ureterolitiasis. ABSTRACTThe obstruction and the urinary stasis are among the most important topics of Urology in all times, due to the devastating effects in the kidneys, including the hydronephrotic atrophy, the infections and the death; besides it results in multiple diseases. Percutaneous nephrostomy was introduced by S. I Seldinger in 1952 and the double catheter J designed in 1978 by Finney facilitate the drainage of the obstructive kidneys, the use of these techniques improve the symptoms allowing the study and in occasions the definitive treatment of the causes. A prospective descriptive study was conducted from November 2003 to December 2008 in the service of Urology at "Abel Santamaria Cuadrado" University Hospital, Pinar del Rio. The sample was comprised of the patients who underwent to minimal access surgery (percutaneous nephrostomy and placement of double J. stents). Nephritic colic was the main cause to attend to the hospital; performing more percutaneous nephrostomies in obstructive ureteral lithiasis in relation to the placement of double JJ catheter, in both procedures the most frequent mediate complications were post-instrument sepsis. The average post-operative hospital staying was 72 hours.Key words: Percutaneous nephrostomy, double JJ catheter

Competencia comunicativa en los estudiantes de medicina: diagnóstico preliminar / Communicative competence in medical students: its initial diagnosisCompetencia comunicativa en los estudiantes de medicina: diagnóstico preliminar / Communicative competence in medical students: its initial diagnosisEl trabajo presenta los resultados de un diagnóstico preliminar sobre la competencia comunicativa en estudiantes de medicina, y es parte de una investigación acerca del desarrollo de esta competencia en los médicos en formación; que persigue el objetivo de diagnosticar la competencia comunicativa en los estudiantes de medicina del tercer año de la carrera, que residen en el municipio de Pinar del Río. Se empleó el método histórico-lógico, que permite hacer una síntesis teórica del proceso de formación de la competencia comunicativa en el individuo en su desarrollo histórico y social, así como de las regularidades y componentes de este proceso. A partir de ahí, se elaboró un instrumento de autoevaluación de los sujetos de la muestra que conforma el campo de la investigación, que se analizó empleando el método estadístico. Como resultado se constata el insuficiente nivel de desarrollo de la competencia comunicativa en los sujetos de la muestra, con solo un 38 %, que califican con el dominio de las habilidades mínimas que necesitan para lograr una comunicación de calidad con sus interlocutores, lo que debe formar parte de su desempeño profesional. El trabajo permite una constatación del problema, además de servir de pilotaje para evaluar la efectividad del instrumento de autoevaluación empleado, que arroja una fiabilidad significativa que abarca el 78% de los encuestados.Palabras clave: COMUNICACIÓN, HISTORIA, LENGUAJE, COMPETENCIA PROFESIONAL/métodos, ESTUDIANTES, EDUCACIÓN.ABSTRACTThis paper presents the results of an initial diagnosis concerning communicative competence in medical students, it  is part of a research about the development of this competence when training medical doctors; having the purpose to diagnose the communicative competence of the medical students enroll in third academic year of medical studies living in Pinar del Rio municipality. Historical-logical method was used, that allows making a theoretical synthesis of the communicative competence in the formation process of the individual within the historical and social development, its regularities and components. Considering these points, an instrument to self-evaluate the subjects included in the sample was created, comprising the field of the research and using the statistical method to analyze it.

We consider special patterns of lengths 5 and 6 in a ternary alphabet. We show that some of them are unavoidable in square-free words and prove avoidability of the other ones. Proving the main results, we use  Fibonacci words as codes of ternary word... see more

Given an infinite word over the alphabet {0,1,2,3}\{0,1,2,3\}, we define a class of bipartite hereditary graphs Ga\mathcal{G}^\alpha, and show that Ga\mathcal{G}^\alpha has unbounded clique-width unless a\alpha contains at most finitely many non-zero lett... see more
