Cubero Rego,David; Cubero Menéndez,Osiris; Cabrera Mehn,Mylene; álvarez Santana,Reinaldo;
Revista Cubana de Medicina , 2004,
Abstract: it has been stated that dementia is the fourth basic cause of death in first world countries. dementia with lewy bodies (dlb) is the second cause of dementia in current necropsic studies, only surpassed by alzheimer's disease. the first cuban case of dementia with lewy bodies was reported. a female white patient aged 89 with clinical diagnosis of dementia that died after 5 years of progressive deterioration. in the neuropathological study, the presence of lewy bodies at the level of the black matter, locus ceruleus and transentorhinal cortex was evidenced by using the haematoxylin/eosin technique. the neurofibrillar pathology assessed by bielschowsky technique corresponded to ii stage braak. a focal espongiform change was identified at the hippocampal level. the diagnosis of lbd variety with predominance of the brain stem was made. literature and the main differential diagnoses were reviewed.
Demencia con cuerpos de Lewy: Presentación de 1 caso Dementia with lewy bodies: A case report
David Cubero Rego,Osiris Cubero Menéndez,Mylene Cabrera Mehn,Reinaldo álvarez Santana
Revista Cubana de Medicina , 2004,
Abstract: Se ha planteado que la demencia constituye la cuarta causa básica de muerte en países del primer mundo. La demencia con cuerpos de Lewy (DCL) constituye la segunda causa de demencia en estudios necrópsicos actuales, superada solo por la enfermedad de Alzheimer. Se reportó el primer caso cubano de demencia con cuerpos de Lewy, una paciente femenina de 89 a os de edad, de la raza blanca, con diagnóstico clínico de demencia, que falleció luego de 5 a os de deterioro progresivo. En el estudio neuropatológico se evidenció con la técnica de hematoxilina / eosina la presencia de cuerpos de Lewy al nivel de la sustancia negra, locus cerúleo y corteza transentorrinal, la patología neurofibrilar valorada con la técnica de Bielschowsky se correspondió con un estadio II de Braak. Se identificó además cambio espongiforme focal al nivel del hipocampo. Se hizo el diagnóstico de DCL variedad a predominio del tallo cerebral. Se revisó la literatura y los principales diagnósticos diferenciales. It has been stated that dementia is the fourth basic cause of death in first world countries.

Santana álvarez,Jorge;
Revista Archivo M??dico de Camag??ey , 2011,
Abstract: background: inverted papilloma is a tumor of frequent location in the nasosinusal region, whose late clinical manifestations and the possibility of recidivation and malignancy requires an exhaustive study and a resolvent treatment. objective: to study the behavior of nasosinusal inverted papilloma in the last nine years. method: a descriptive and longitudinal study of nasosinusal inverted papilloma was conducted at the university military hospital dr. octavio de la concepción y de la pedraja of camagüey, from 2001 to 2009. variables like age, sex, race, symptoms and signs, surgical technical classification and evolution after therapeutics were analyzed. results are commented and also compared. results: in the six studied patients with the diagnosis of the disease, the destructive picture was accompanied by rhinorrhea; however in one of them, the cause that motivated the request of secondary attention was the expulsion of tumor′s remains. in the 83,3 % of cases, by its extension and location, the tumor was located in the stages ii and iv of krouse, previous endoscopic and imaging study to assessed its extension and staging. combined or external surgery was accomplished, with the gained experience, results were compared with another authors. conclusions: nasosinusal inverted papilloma may appear for the fist time with different clinical manifestations, being nasal obstruction the most frequent. it is define the importance of the complete removal to achieve the success of the surgical treatment and a low rate of recidivation.
Indumentária funk: a confronta??o da alteridade colocando em diálogo o local e o cosmopolita
Mizrahi, Mylene;
Horizontes Antropológicos , 2007, DOI: 10.1590/S0104-71832007000200010
Abstract: the article aims to comprehend the logics governing the appropriation and consumption of the elements that compose the funk attire, through the dialogue between the classificatory systems and the approaches that focuses upon the materiality of the object. in order to do that, the funk taste will be taken in its transit between the party and daily life, which includes the come and go from the "favelas" to other areas of the city, as the ball itself, school and work. from this point of view, the brands of the garments are seen as indicators of a tense relation with modernity, wherein the conflict appears as a constituent trait of the youngsters sociality and structuring element of their cosmology.
Funk, religi?o e ironia no mundo de Mr. Catra
Mizrahi, Mylene;
Religi?o & Sociedade , 2007, DOI: 10.1590/S0100-85872007000200006
Abstract: the article main aim is to discuss the relation between funk and religion, through the mr. catra's narratives, singer and performer of this musical rhythm. his singularity resides in adding religion to a universe traditionally apprehended as erotic or violent. the artist allows us to articulate his own creation both to his worldview as to the point of view of the youngsters from the favelas slums, main producers and consumers of funk music. the discourse around the divine, present at the artist's performances, is deepen in his daily life, consisting of a medium for expressing his own political position in the world. although the religious discourse is privileged by mr. catra in his will to show his way of understanding the world, the funk strength resides in another aspect, that go by party and daily life. it is the irony itself, so artfully played by the artist, that allows us to realize how the funk is ingenious at, through the laugh, destabilizing the power by a subversive manipulation of cultural symbols dear to the oppressive authority.
La dimensión fronteriza de la política exterior de Chile: inmovilidad y emergencia de nuevas dinámicas
Ovando Santana, Cristian;álvarez Fuentes, Gonzalo;
Estudios fronterizos , 2011,
Abstract: the following article draws the priorities of border public policy that define the chilean foreign policy. through a theoretical framework from the rational-reflective approach of international relations, we argue that despite of the increasing openness, internationalization of the country, and the emergence of new actors and subnational initiatives; the views and options between the actors of this new area and the definitions of foreign policy not always match. we propose the need to establish mechanisms that settle the positions among regional social-political actors, intermediate agencies and the central level.
El Consejo de Defensa Suramericano: posibilidades de integración desde una perspectiva constructivista
álvarez Fuentes,Gonzalo; Ovando Santana,Cristian;
Papel Politico , 2009,
Abstract: historically the latin american's state nations have shown a serie of domestic and international edges that have hampered the consolidation of the processes designed to achieve greater levels of agreement and regional integration. these factors have prevented the position of the continent in the global system as a more autonomous and consistent region. however, in the first decade of this century, the south american defense council stands as a unique opportunity for regional integration, considering its exclusive latin american nature and the goals presented by the institution. based on the theoretical framework that provides the constructivist debate about the international relations, the following article are identified those key factors in the newly formed organization and that could be combined to achieve a greater concerted and regional integration, without neglecting the critical factors that could undermine the goals set by the council.
A review of the application and contribution of discrete choice experiments to inform human resources policy interventions
Mylene Lagarde, Duane Blaauw
Human Resources for Health , 2009, DOI: 10.1186/1478-4491-7-62
Abstract: We carried out a literature review of studies using discrete choice experiments to investigate human resources issues related to health workers, both in developed and developing countries. Several economic and health systems bibliographic databases were used, and contacts were made with practitioners in the field to identify published and grey literature.Ten studies were found that used discrete choice experiments to investigate the job preferences of health care providers. The use of discrete choice experiments techniques enabled researchers to determine the relative importance of different factors influencing health workers' choices. The studies showed that non-pecuniary incentives are significant determinants, sometimes more powerful than financial ones. The identified studies also emphasized the importance of investigating the preferences of different subgroups of health workers.Discrete choice experiments are a valuable tool for informing decision-makers on how to design strategies to address human resources problems. As they are relatively quick and cheap survey instruments, discrete choice experiments present various advantages for informing policies in developing countries, where longitudinal labour market data are seldom available. Yet they are complex research instruments requiring expertise in a number of different areas. Therefore it is essential that researchers also understand the potential limitations of discrete choice experiment methods.The importance of human resources for health systems is demonstrated by ecological evidence of a positive correlation between the population density of health care providers in a country and the coverage achieved for cost-effective health interventions such as immunization or skilled attendance at delivery [1,2]. Several recent initiatives and reports have focused on the critical role played by human resources (HR) for health in improving health system performance [3-5]. It is now widely acknowledged that adequate he
The impact of user fees on health service utilization in low- and middle-income countries: how strong is the evidence?
Lagarde,Mylene; Palmer,Natasha;
Bulletin of the World Health Organization , 2008, DOI: 10.1590/S0042-96862008001100013
Abstract: objective: to assess the effects of user charges on the uptake of health services in low- and middle-income countries. methods: a systematic search of 25 social science, economics and health literature databases and other sources was performed to identify and appraise studies on the effects of introducing, removing, increasing or reducing user charges on the uptake of various health services in low- and middle-income countries. only experimental or quasi-experimental study designs were considered: cluster randomized controlled trials (c-rct), controlled " before and after" (cba) studies and interrupted time series (its) studies. papers were assessed in which the effect of the intervention was measured in terms of changes in service utilization (including equity outcomes), household expenditure or health outcomes. findings: sixteen studies were included: five cba, two c-rct and nine its. only studies reporting effects on health service utilization, sometimes across socioeconomic groups, were identified. removing or reducing user fees was found to increase the utilization of curative services and perhaps preventive services as well, but may have negatively impacted service quality. introducing or increasing fees reduced the utilization of some curative services, although quality improvements may have helped maintain utilization in some cases. when fees were either introduced or removed, the impact was immediate and abrupt. studies did not adequately show whether such an increase or reduction in utilization was sustained over the longer term. in addition, most of the studies were given low-quality ratings based on criteria adapted from those of the cochrane collaboration's effective practice and organisation of care group. conclusions: there is a need for more high-quality research examining the effects of changes in user fees for health services in low- and middle-income countries.
An asymptotic log-Fourier interpretation of the R-transform
Alice Guionnet,Mylene Maida
Mathematics , 2004,
Abstract: We estimate the asymptotics of spherical integrals when the rank of one matrix is finite. We show that it is given in terms of the R-transform of the spectral measure of the full rank matrix and give a new proof of the fact that the R-transform is additive under free convolution. These asymptotics also extend to the case where one matrix has rank one but complex eigenvalue, a result related with the analyticity of the corresponding spherical integrals.
