ABSTRACT
Myelodysplastic syndrome (MDS) is cytogenetically heterogeneous and retains variable risk for acute myeloid leukemia transformation. Though not yet fully understood, there is an association between genetic abnormalities and defects in gene expression. The functional role for infrequent cytogenetic alteration remains unclear. An uncommon chromosomic abnormality is the presence of the Philadelphia (Ph) chromosome. Here, we report a patient with Ph+ MDS treated with low dose Dasatinib who achieved hematologic response for 7 months. In addition, we also examined the English literature on all de novo Ph + MDS cases between 1996 and 2015 to gain insight into clinical features and outcome.
ABSTRACT
INTRODUCTION: Fewer than 5% of patients have nonsecretory multiple myeloma (NSM), which is characterized by the absence of monoclonal protein in immunofixation in serum and urine. There are limited data on the outcome of NSM after autologous hematopoietic stem cell transplantation (auto-HCT). PATIENTS AND METHODS: Between 1988 and December 2010, we identified 31 patients with NSM, and compared their outcome with 124 patients with secretory myeloma (SM) who were matched for age, disease stage, year of auto-HCT, and disease status and received auto-HCT at our institution. The primary end points were time to progression (TTP), progression-free survival (PFS), and overall survival (OS). RESULTS: Nonrelapse mortality at 4 years was 4% and 4% in the NSM and SM patients, respectively (P = .612). Median follow-up was 102 and 74 months for NSM and SM patients, respectively. Median PFS was 37 (95% confidence interval [CI], 12-62) and 22 (95% CI, 18-26) months for NSM and SM patients, respectively (P = .527). Median OS was 51 (95% CI, 7-95) and 73 (95% CI, 59-86) months for NSM and SM patients, respectively (P = .740). In multivariate analyses, age >55 years, and relapsed disease were associated with a shorter TTP. Similarly, age >55 years, and relapsed or refractory disease at the time of auto-HCT were associated with a shorter OS. CONCLUSION: Auto-HCT is associated with durable remission in NSM. There was no significant difference in transplant-related mortality, TTP, and PFS in patients with NSM compared with patients with SM after high-dose therapy and auto-HCT.

El artículo médico: La Clase Dialogada publicado por la profesora Luisa Teresa Silva en 1982 es pionero en la Facultad de la Docencia en Medicina Centrada en el estudiante (DMCE). Este artículo tiene como propósitos: 1) transcribir el desarrollo de un foro donde se evaluó con las Escuelas de la Facultad de Medicina, la percepción de esta estrategia docente, que cada día tiene más adeptos entre estudiantes y profesores, 2) honrar y recordar a la profesora Silva por su memorable contribución pedagógica. 3) describir, evaluar y analizar la metodología empleada en la ejecución de un foro con estudiantes de Medicina y 4) organizar sus resultados para la publicación como artículo médico en una revista de difusión científica. El evento tuvo lugar el 30 de enero de 2008, en la Escuela de Medicina JM Vargas. Se elaboró una encuesta con cuatro preguntas cerradas, sobre: cómo se enteraron de la actividad, la manera cómo fue organizada, participación en la docencia centrada en el estudiante y cuál estrategia docente prefiere, la cual se distribuyó a los asistentes. El foro se inició con una tormenta de ideas, prosiguió una mesa redonda sobre el devenir histórico y las estrategias docentes. Seguidamente se oyó la participación de los profesores asistentes de las diferentes escuelas de la Facultad, una sesión de preguntas y respuestas y el cierre se realizó con la clase magistral La autonomía universitaria en las Escuelas de Ciencias de la Salud a cargo de la Profesora Cecilia García Arocha, para la fecha Secretaria de la UCV. De los 262 inscritos en el foro, 64 (24,4 %) entregaron la encuesta completada. Del análisis de las respuestas se pudo concluir que la DMCE incorpora activamente al alumno y al docente en la búsqueda activa del conocimiento, lo cual supera el tradicional esquema de docencia centrada en el profesor, por el rol pasivo del estudiante en esta última modalidad...
The paper The Dialogued Class published by Professor Luisa Teresa Silva in 1982 is considered in the Faculty of Medicine as a pioneer of Medical Teaching Centered in the Student (MTSC). The present publication has the following objectives: 1) Transcribe the forum carried out in order to evaluate the perception held by different members of the Faculty regarding about these teaching strategies, which have gained more acceptance in students and professors every day, 2) Honor and remember Professor Silva for her memorable pedagogic contribution, 3) Describe, evaluate and analyze the methodology used in the execution of a forum made with medical students, and 4) Organize the results for publication as a medical article in a scientific magazine. The event took place on the 30th of January 2008, in the Medical School Jose María Vargas. A questionnaire was made with four closed questions: 1) How the assistants learned about the activity, 2) Considerations about the quality of the event organization, 3)Participation and preferences in the teaching strategy centered in the student. The questionnaire was delivered to the assistants. The forum was initiated with a brainstorm session and continued with a round table discussion about the historical outcome of the teaching strategies, followed by comments from professors of the different Health Science Schools in the Faculty, a session with questions and answers, and a closure with the lecture: The university autonomy in all the Science Health Schools, by Professor Cecilia Garcia Arocha, by the time, Secretary of the UCV. There were 262 persons registered in the forum and only 64 (24.4 %) returned the filled questionnaire. In conclusion, the MTSC actively incorporates students and professors in an active search for knowledge that overcomes the traditional teaching system, centered on the professor, with a passive role from the student...
