Dengue, Dengue hemorrágico
Pizarro,Daniel;
Acta Pediátrica Costarricense , 2009,
Abstract: el dengue ó fiebre por dengue, es una enfermedad febril producida por uno de los cuatro serotipos del virus dengue, que pertenecen al grupo de virus transmitidos por artrópodos (arthropod-borne-virus ó arbovirus). la transmisión se hace por medio de la hembra del mosquito aedes aegypti, que pertenece al género flavivirus de la familia flaviridae. el dengue es la enfermedad transmitida por vectores más frecuente en todo el mundo. desde 1993 en costa rica el dengue es una enfermedad endémica en las costas del océano pacífico y del mar caribe. durante estos a?os y hasta el 8 de septiembre del 2007 la prevalencia de dengue clásico es de 4.087 casos por 100.000 habitantes, de dengue hemorrágico 14 casos por 100.000 habitantes para una tasa de letalidad por dengue hemorrágico de 0.02%. entre la inoculación del virus por la mosquita aedes y la aparición de los síntomas hay un lapso de 3 á 14 días, en promedio 7 días. es el período de incubación de la enfermedad. existen 4 grupos antigénicos o serotipos de virus del dengue: den-1, den-2, den- 3 y den-4. el den-1 tiene sólo 7 biotipos, y el den-2, 34 biotipos. las hemorragias que se producen en el dengue son el producto de las lesiones en el endotelio vascular, de la trombocitopenia, de la disfunción de las plaquetas y de la alteración de los factores de coagulación. la lesión de las "esclusas" de la zonula occludens provoca un escape de líquidos del espacio intra-vascular al espacio extra-vascular. la hipovolemia desencadena una serie de respuestas homeostáticas que tienen como fin mantener una mejor perfusión de los órganos más nobles de la economía en detrimento de otros órganos como son la piel y los músculos. el periodo febril dura de 3 á 7 días, y el día de la defervescencia (día cero) el paciente evolucionará hacia la convalecencia ó hacia el dengue hemorrágico. en los primeros días suele aparecer exantema generalizado, con palidez de la piel al hacer presión sobre ella. las manos y pies se tornan hiperhémicos y en la

Abstract: in this contribution, the shared articulation of a latin-american space from the multiplicity of its cultural areas is approached through fernando pessoa?s metaphor of heteronomy. relations between hispanic-america and brazil are especially taken into account. from a structural outlook, both cultural blocks have productive symbolic nucleus which articulate themselves by integrating tensions of our culture in its peripheral conditionings. thus, the construction of an emergent alternative space during the colonial period, as well as the national homogeneity esthetics and the regional-cosmopolitan tensions of modernization give them a sense of "unity" -even if they also show their divergences. today, besides exploring the effect of media on these links, it is interesting to approach -maintaining an overall viewpoint- concrete historical relations established by single travelers and intellectuals such as gabriela mistral. the conclusion is that it is pertinent to examine different spaces of contact between brazil and hispanic-america, such as conceptual delimitations, external axis, travels and frontiers. among these, the amazonian region is profiled as one which is urgent to become acquainted with in order to vindicate its belonging to latin america
Voces del seringal: discursos, lógicas, desgarramientos amazónicos
Pizarro,Ana;
Literatura y lingüística , 2006, DOI: 10.4067/S0716-58112006000100003
Abstract: in this article we analyze three kind of discourses raised around the boom of amazonian syringe and rubber extraction (c. 1900): the first one epically enlarges the so-called "rubber lords" as "individuating" personalities; the second one, created by intellectuals of the period, denounces the oppression of the workers of the "seringal" and of the native inhabitants; the third one corresponds to direct testimonies of these subjects, as well as to the mythical memories of their communities
"CIUDADANOS BONAERENSES-BOLIVIANOS": ACTIVISMO POLíTICO BINACIONAL EN UNA ORGANIZACIóN DE INMIGRANTES BOLIVIANOS RESIDENTES EN ARGENTINA
PIZARRO,CYNTHIA;
Revista Colombiana de Antropología , 2009,
Abstract: this paper analyzes the way in which the political activism developed within an organization of bolivian migrants living in argentina build a bi-national political space. it means a scenario where those migrants where recognized as citizens by authorities of different levels both bolivian and argentinean. the argument lies in a ethnographic description that covers the structure of political opportunities that facilitates the construction of this space, the characteristics of the bolivian migration in the north of the metropolitan area of the city of buenos aires, the trajectory of the organization in relation to the local political scenario and the conformation of alliances between the authorities of different argentine state levels (local, regional, national) based in political parties affinities. finally, there is a discussion about the relevance that the migratory question has gained in the recent years in argentina and bolivia
CARMEN MIRANDA Y LA ESTéTICA DEL EXCESO
PIZARRO,ANA;
Atenea (Concepción) , 2009, DOI: 10.4067/S0718-04622009000200002
Abstract: in this paper i analyze the novel las noches de carmen miranda (2002) by the chilean writer lucía guerra as part of the imaginary on brazilian actress carmen miranda (1909-1955). as a latin-american icon of international mass culture, carmen miranda develops an esthetics of excess that is recognizable in its over elaborated tropical style. lucía guerra's text incorporates kitsch as a theme, but fails to do the same with the sensibility of a personage that is complex from the point of view both of the historical context and esthetics.
Tras las huellas de la identidad en los relatos locales sobre el pasado
Pizarro,Cynthia;
Cuadernos de antropolog?-a social , 2006,
Abstract: in this paper i argue that local stories about the past are not mere descriptions of events but they re-signify, reproducing or transforming, elements of common sense. thus, an analysis that not only regards to their referential issues leads to the comprehension of the various ways in which social agents construct their identity. in this opportunity i refer to the theorical and methodogical framework that i have designed to explain the senses of belonging and forthcoming which local inhabitants of a rural area of the province of catamarca, argentina, articulate in their stories about the past. i also consider the tension that has crossed over the whole research process since i bared in mind the incidence of my own reflexivities not only in the interpretation of the data but also in the construction of the research object.
La crisis del pimiento: presupuestos, saberes y poderes en Santa María, Catamarca
Pizarro,Cynthia;
Cuadernos de la Facultad de Humanidades y Ciencias Sociales. Universidad Nacional de Jujuy , 2000,
Abstract: this paper focuses on the way in which some social subjects concerned with the red pepper production in the locality of santa maría, catamarca, made sense of a conflict in the chain of production through their own presuppositions and knowledges. the aim is to analyze their explanations, through the identification of the presuppositions, the definition of the problem and its causes, and the possible solutions. the backing of this study is a corpus of semi-structured interviews which were done in the locality between 1992 and 1993. the diagnosis and prognosis of the crisis made by those subjects are compared, relating them to their underlying paradigmatic presuppositions. the significant differences found are not due to the kind of knowledges: scientific or common sense. on the contrary, they are related with the incidence, on both kind of knowledges, of different kind of paradigmatic presuppositions about the relation between theory and practice, knowledge and power. the definitions of the crisis are analyzed, then, considering the presuppositions about the what to know, what to know for and who to know for that characterize three different paradigms: the positivist, the interpretative and the critic ones. it is argued that the productivist and positivist presuppositions underlie the rural extension practices in the area. this factor constrains the possibilities of the small productors because their social situation of socio-structural inequality is not considered and, if it is, it is minimized from a reductionist point of view that stereotypes them us self-minded, stubborn and traditional.
Mal praxis en el equipo médico
Pizarro,Carlos;
Revista médica de Chile , 2011, DOI: 10.4067/S0034-98872011000500016
Abstract: to be successful, modern medical acts require the participation ofseveral professionals and assistants and, as such, there has been a steady trend from individual medicine to the collective practice of the profession. this format raises issues in determining when a medical professional or other practitioner is liable for the acts of a colleague. this thesis proposes to resolve the problems involved in the collective practice of medicine by restricting liability to a physician responsible for another practitioner, only to those cases where he/she has been willingly introduced into the medical act.
Voces del seringal: discursos, lógicas, desgarramientos amazónicos
Ana Pizarro
Literatura y lingüística , 2006,
Abstract: En este artículo se analizan tres discursos originados en torno al auge extractivista de la seringa y el caucho amazónicos (c. 1900): el primero engrandece épicamente a los llamados "barones del caucho" como figuras "individuantes"; el segundo, elaborado por intelectuales del período, denuncia la opresión de los trabajadores del seringal y las poblaciones indígenas; el tercero corresponde al testimonio directo de estos últimos, así como a la rememoración mítica de sus comunidades In this article we analyze three kind of discourses raised around the boom of Amazonian syringe and rubber extraction (c. 1900): the first one epically enlarges the so-called "rubber lords" as "individuating" personalities; the second one, created by intellectuals of the period, denounces the oppression of the workers of the "seringal" and of the native inhabitants; the third one corresponds to direct testimonies of these subjects, as well as to the mythical memories of their communities
Hispanoamérica y Brasil: Encuentros, desencuentros, vacíos
Ana Pizarro
Acta Literaria , 2004,
Abstract: A partir de la metáfora de la heteronimia elaborada por Fernando Pessoa, se aborda el problema de la articulación común de un espacio latinoamericano en función de la multiplicidad de sus áreas culturales, considerando en particular las relaciones entre Hispanoamérica y el Brasil. Desde una mirada estructural, se advierte que en ambos bloques existen núcleos de productividad simbólica que se articulan al incorporar las tensiones propias de nuestra cultura en su condicionamiento periférico. Así, la construcción de un espacio alternativo emergente en la colonia, la estética de la homogeneidad nacional y la tensión regional-cosmopolita de la modernización son dispositivos que otorgan un sentido de "unidad" a estos bloques, si bien evidenciando asimismo sus divergencias. Hoy, además de explorar el efecto que sobre estas vinculaciones tiene la introducción de la escena mediática, se plantea el interés de aproximarse, manteniendo una mirada de conjunto, a las relaciones históricas concretas establecidas por viajeros e intelectuales, como es el caso de Gabriela Mistral. Se concluye postulando la pertinencia de examinar los distintos espacios de contacto entre estos bloques, tales como las delimitaciones conceptuales, los ejes externos, los viajes y las fronteras. Dentro de ellos, la Amazonía se perfila como una región que urge conocer en la perspectiva de reivindicar su pertenencia In this contribution, the shared articulation of a Latin-American space from the multiplicity of its cultural areas is approached through Fernando Pessoa’s metaphor of heteronomy. Relations between Hispanic-America and Brazil are especially taken into account. From a structural outlook, both cultural blocks have productive symbolic nucleus which articulate themselves by integrating tensions of our culture in its peripheral conditionings. Thus, the construction of an emergent alternative space during the colonial period, as well as the national homogeneity esthetics and the regional-cosmopolitan tensions of modernization give them a sense of "unity" -even if they also show their divergences. Today, besides exploring the effect of media on these links, it is interesting to approach -maintaining an overall viewpoint- concrete historical relations established by single travelers and intellectuals such as Gabriela Mistral. The conclusion is that it is pertinent to examine different spaces of contact between Brazil and Hispanic-America, such as conceptual delimitations, external axis, travels and frontiers.
