Abstract: INTRODUCCIóN. El cáncer de mama es la primera causa de muerte por cáncer en la mujer y se ha convertido en una pandemia que amenaza continuar si no se halla la forma de prevenirlo. El objetivo de este trabajo fue evaluar la supervivencia global y el intervalo libre de enfermedad en pacientes que recibieron como tratamiento inicial cirugía conservadora más radioterapia y mastectomía radical modificada; y determinar otras variables pronósticas, como la edad, clínicas histológicas, recaídas y tiempo entre la cirugía y la radioterapia. MéTODOS. Entre enero del 2000 y diciembre del 2005 se realizó en el Hospital Julio Trigo López un estudio retrospectivo y descriptivo de un grupo de pacientes con cáncer primario de mama, en etapas I y II. Los datos se extrajeron de las historias clínicas y de encuestas. Se creó una base de datos y se realizó un análisis descriptivo de los datos, frecuencia y porcentajes para el caso de las variables cualitativas y medias, y desviaciones estándares para las cuantitativas. Se estimó la supervivencia y el intervalo libre de enfermedad utilizando el método de Kaplan Meir y se compararon en curvas según las variables de interés de Sug Rank. El análisis de las variables pronósticas de supervivencia e intervalo libre de enfermedad se realizó mediante análisis de regresión de Cox. RESULTADOS. El intervalo libre de enfermedad fue mayor en la cirugía conservadora que en la mastectomía radical modificada, y de igual manera se comporto la supervivencia global. Las pacientes con Rh positivo presentaron mayor intervalo libre de enfermedad (88 %). El carcinoma infiltrante fue la variedad más frecuente y de mayor número de recaídas, en las cuales influyó el tiempo entre la cirugía y la radioterapia. La frecuencia más alta de cáncer de mama se observó en las mujeres mayores de 50 a os. En la cirugía conservadora predominó la conducta terapéutica de cirugía más radioterapia y quimioterapia y en la mastectomía radical modificada, la quimioterapia. En la cirugía conservadora fueron más frecuentes las recaídas locorregionales, mientras que en la mastectomía radical, las recaídas más frecuentes se registraron a distancia. CONCLUSIONES. El tipo de cirugía no influyó significativamente en el intervalo libre de enfermedad, pero sí hubo diferencias entre las técnicas conservadoras. Los factores pronósticos tama o del tumor, estado ganglionar y receptores hormonales influyeron en la supervivencia y en el intervalo libre de enfermedad en todas las pacientes. INTRODUCTION.

Abstract: introduction. at present, the acute pelvic inflammatory disease is considered a syndrome clinically attributed to the ascending passage of microorganisms from the vagina to the cervix, the endometrium and the fallopian's tubes. it is also capable of disseminating to the neighbouring structures. the objective of this paper was to know the behaviour of the disease, the efficiency of some diagnostic aids and procedures, the performance of the haematological tests, and to identify the most common germs to define the further conduct. methods. the study group consisted of 108 females seen at "julio trigo lópez" hospital due to an acute inflammatory pelvic disease. the sample was selected at random and variables such as general and health data and data from the gynecoobstetric history were registered. vaginal manipulation, with anaesthesia or without it, puncture of douglas' pouch, ultrasound, laparoscopy, red-blood cell count, white-blood cell count, and erythrosedimentation were used to make the diagnosis. laparoscopy was used in all cases as a confirmatory test. results. most of the patients were aged 20-25. abdominal pain (98.1 %) and leucorrhoea (30.6 %) predominated as clinical symptomatology. a high incidence of this disease was observed in females at reproductive age, with 2 or more pregnancies and abortions and history of implanted intrauterine device. moreover, there was a diagnostic concordance between the results of the vaginal manipulation and ultrasound, on comparing them with laparoscopy. the least specific test was vaginal manipulation (20.5 %) and the predictive values of the lowest positive test were obtained with the same procedure (64.6 %), as well as with erythrosedimentation (70 %). therefore, ultrasound proved to be the most effective diagnostic aid (87,5 %) after laparoscopy. conclusions. it was concluded that ultrasound (77 %) is the most effective test compared with laparoscopy, followed by vaginal manipulation (70 %)

Abstract: INTRODUCCIóN. Hoy día la enfermedad inflamatoria pélvica aguda se considera un síndrome clínicamente atribuido al paso ascendente de microorganismos desde la vagina al cérvix, hasta el endometrio y las trompas de Falopio, y que es capaz de diseminarse a las estructuras vecinas. Fueron objetivos de esta publicación conocer el comportamiento de la enfermedad, la eficiencia de algunos medios y procedimientos diagnósticos y el comportamiento de las pruebas hematológicas e identificar los gérmenes más frecuentes para definir la conducta posterior. MéTODOS. El universo estuvo conformado por 108 mujeres atendidas en el Hospital Julio Trigo López a causa de una enfermedad inflamatoria pélvica aguda. Se seleccionó la muestra aleatoriamente y se registraron en una encuesta variables como datos generales y de salud y de la historia ginecoobstétrica. Para el diagnóstico clínico se realizó tacto vaginal, con anestesia o sin ella, punción del saco de Douglas, ultrasonido, laparoscopia, hemograma, leucograma y eritrosedimentación. En todos los casos se utilizó la laparoscopia como prueba comprobatoria. RESULTADOS. La mayoría de las pacientes tenían edades entre los 20 y 25 a os. El dolor abdominal (98,1 %) y la leucorrea (30,6 %) predominaron como sintomatología clínica. Se encontró una alta incidencia de esta enfermedad en mujeres en edad reproductiva, con dos o más embarazos y abortos y el antecedente de dispositivo intrauterino implantado. Además, hubo concordancia diagnóstica entre los resultados aportados por el tacto vaginal y el ultrasonido, al compararlos con la laparoscopia. La prueba menos específica fue el tacto vaginal (20,5 %) y los valores predictivos de la prueba positiva más baja también lo aportó el mismo proceder (64,6 %), así como la eritrosedimentación (70 %). Por tanto, después de la laparoscopia, el medio más efectivo fue el ultrasonido (87,5 %). CONCLUSIONES. Se concluyó que la prueba más eficiente en comparación con la laparoscopia es el ultrasonido (77 %), al cual siguió el tacto vaginal (70 %) INTRODUCTION.

Abstract: How is software measurement addressed in undergraduate and graduate programs in universities? Do organizations consider that the graduating students they hire have an adequate knowledge of software measurement? To answer these and related questions, a survey was administered to participants who attended the IWSM-MENSURA 2010 conference in Stuttgart, Germany. Forty-seven of the 69 conference participants (including software development practitioners, software measurement consultants, university professors, and graduate students) took part in the survey. The results indicate that software measurement topics are: 1) covered mostly at the graduate level and not at the undergraduate level, and 2) not mandatory. Graduate students and professors consider that, of the measurement topics covered in university curricula, specific topics, such as measures for the requirements phase, and measurement techniques and tools, receive more attention in the academic context. A common observation of the practitioners who participated in the survey was that students hired as new employees bring limited software measurement-related knowledge to their organizations. Discussion of the findings and directions for future research are presented.

Abstract: introduction. breast cancer is the first cause of death from cancer in females and it has become a pandemic threatening to continue if the way to prevent it is not found. the objective of this paper was to evaluate global survival and the disease free interval in patients that underwent conservative surgery plus radiotherapy and modified radical mastectomy as initial treatment, and to determine other prognostic variables, such as age, histological clinics, relapses and time elapsed between surgery and radiotherapy. methods. a retrospective and descriptive study was conducted in a group of patients with stage i and ii primary breast cancer at ?julio trigo lópez? hospital from january 2000 to december 2005. data were taken from the medical histories and surveys. a database was created and a descriptive analysis was made of the data, frequency and percentages for the case of qualitative and mean variables, and of the standard deviations for the quantitative variables. survival and the disease free interval were estimated by kaplan meir's method and they were compared by curves according to the sug rank's variables of interest. the analysis of the prognostic variables of survival and disease free interval was carried out by cox's regression analysis. results. the disease free interval was longer in conservative surgery than in the modified radical mastectomy. global survival had a similar behaviour. patients with positive rh presented a longer disease free interval (88 %). the infiltrating carcinoma was the most frequent variety and it had the greatest number of relapses, which were influenced by the time elapsed between surgery and radiotherapy. the highest frequency of breast cancer was observed in females over 50. the therapeutic conduct of surgery plus radiotherapy and chemotherapy prevailed in conservative surgery, whereas chemotherapy predominated in the modified radical mastectomy. the locoregional relapses were more common in conservative surgery; however, the m

Acta literaria , 2006, DOI: 10.4067/S0717-68482006000100006
Abstract: in el almuerzo del solitario, efraín jara idrovo (cuenca, 1926) conceives the everyday as something banal that impedes any attempt of a transcendance which is only possible to acheive by means of existencial intensification. it is a poem in which the poet tries to subject loneliness, time and death, consecrating their full acceptance by means of the enjoyment of simple pleasures and frugal gifts which induce the harmony of the subject withim himself and with the universe
República, nación y democracia ante el desafío de la diversidad

Abstract: republic is not only the name of a nation and its regime. it is also a national model of integration based on a universalist conception of citizenship that sustains the abstract figure of the legal person, endowed with equal rights and obligations, and values of civism and civility, the foundation stones of a society that arises from a contract. this paper analyses how the emergency of the cultural diversity in argentina calls into question modern political concepts like republic, nation and democracy. it is also evaluated how the republic's inheritance, which supposes an homogenized sight of diversity, gives rise to an ambivalence among the adherence to universalist principles of the progress of humanity and the reality of an excluding democracy that gave value to one culture above others. the narratives of national identity are studied describing how the opposition between civilization and barbariy affects the way latin americans see the great challenges presented by the future of democracy, and by the recognition of the plurality of cultural allegiances.

Abstract: this article analyzes whether the strategy displayed by rawls starting with the dewey lectures makes it possible to overcome the comprehensive character that some critics attribute to his political conception of person. after describing said conception, the paper reviews the objection that it is incompatible with those conceptions of the good that attribute a constitutive character to attachments and ends. finally, it is concluded that although the distinction between political and comprehensive liberalism is unstable, it is compatible with constitutive conceptions of the good.
CIUDADANíA Y CIVILIDAD: acerca del derecho a tener derechos
Villavicencio,Susana;
Colombia Internacional , 2007,
Abstract: in a context of neoliberalism and deepening socioeconomic inequality in latin america, the author analyzes the concept of citizenship and its articulation with the concept of civility. citizenship has been defined as a status that guarantees rights and duties, liberties and restrictions, and powers and responsibilities to equal individuals. this is why the concept of citizenship occupies a central place in democratic politics. but exclusion, growing inequality and the absence of conditions for the exercise of rights shows that the concept of citizenship is insufficient and reveals a gap to fill.the need to link this concept to the expectations of recognition contained in the idea of civility leads the author to ask for the paradoxes of liberal democracy, and to question the existing gap between ideal rights and their actual exercise, which points to the extent of the task of developing a real democracy.
