RESUMEN

Objetivos
Determinar la frecuencia de la aplicación diagnóstica de la ventana pericárdica en pacientes con traumatismos torácicos abiertos (TTA) del Centro de Emergencias Médicas (CEM) y; comparar la exactitud de la ventana pericárdica subxifoidea (VPS) en el diagnóstico de patologías post traumáticas torácicas respecto a métodos no invasivos (Ecopericardio - EP).

Materiales y métodos
Se realizó un estudio observacional analítico retrospectivo que abarca los meses de Enero a Diciembre del año 2010 y los meses de Enero a Mayo del año 2011. Se analizaron durante el periodo de estudio un total de 26 pacientes con traumatismo torácico abierto y aplicación de VPS. Se acudió a los registros de sala de Cirugía del CEM, de manera que el estudio se sustenta en información de fuente secundaria, utilizándose métodos de representación estadística.

Resultados
De 322 casos de trauma torácico abierto, 26 casos con ecopericardio indeterminado (8,07%) fueron analizados. De tales casos y utilizando como método diagnóstico secundario la VPS, 22 resultaron positivos (84,61%) evitando lesiones cardíacas severas con posible derivación fatal en éstas y toracotomías innecesarias en las restantes 4 personas (15,39%).

Conclusión
La aplicación diagnóstica de Ventana Pericardica Subxifoidea (VPS) es la forma más sensible y específi ca de determinar lesiones cardiacas con compromisos vitales ante una prueba diagnóstica no invasiva (ecopericardio) con resultado no concluyente.

ABSTRACT

Background
Trauma prevention made in the childhood presents great effectiveness for it is in this age that habits and values of safety and citizenship are created. This research intends to analyze which preventive measures are more frequently adopted by the parents of 0 to 12-year-old children and find the relation between prevention and family income.

Study design
For data collection we handed questionnaires to the parents of children studying in public and private schools in Curitiba-PR, Brasil. The information obtained was analyzed by the programs Epi Info® and Excel®.

Results
A total of 609 questionnaires were analyzed 291 children (47.8%) were female and 318 (52.2%) were male. From the total, 604 (99.2%) declared to take at least one preventive measure. The most common measures were: 'leaving the handle of the pan inward the stove' with 562 (92.28%), 'wearing seat belt' with 560 (91.95%) and 'leaving medicines and chemical products out of reach' with 541 (88.83%). The parents marked on the questionnaires which measures they adopted with their children out of a list with eight examples. Families with the income of 1 minimum wage (MW) had an average of 2.92 marked options; with the income of 1 to 3 MWs an average of 3.6; 3 to 6 MWs an average of 4.73; 6 to 10 MWs average of 4.91 and above 10 MWs average of 5.31.

Discussion
Even though most of the families used at least one kind of preventive measure with their children, the family income has marked influence on the amount and type of adopted measures.

Fatores Relacionados aos Óbitos em Vítimas de Trauma Fechado com Probabilidade de Sobrevivência Estimada Superior a 75%
Authors: Kaiser CR , Silva DV , Parreira JG , Assef JC , Margarido AC 
Published: October 2012

RESUMO

Introdução
O estudo dos óbitos evitáveis traz importantes informações para melhoria do atendimento e prevenção de novos eventos adversos. Os óbitos em doentes com TRISS superior a 75% precisam ser analisados com cautela, pois podem ser considerados como evitáveis caso os fatores envolvidos não justifi quem a evolução desfavorável.

Objetivo
Identificar fatores relacionados às mortes ocorridas em vítimas de trauma fechado com probabilidade de sobrevivência estimada superior a 75%.

Metodologia
Análise retrospectiva de protocolos de atendimento em trauma, coletados em junho de 2008 a setembro de 2009. Foram incluídas na amostra todas as vítimas de trauma fechado, com idade superior a 13 anos e com informações que permitiram o cálculo do TRISS (mecanismo, idade, RTS e ISS) e cuja probabilidade de sobrevivência era superior a 75%.

Resultados
Do total, 3142 (98,6%) dos pacientes apresentaram valores superiores a 75%. O principal mecanismo de trauma encontrado foi acidente de motocicleta (25%). Vinte e cinco pacientes (0,8%) foram a óbito, principalmente em virtude de trauma cranioencefálico (56%). Os doentes que morreram apresentaram, signifi cativamente, maior média de AIS em região cefálica (3,32 vs 0,57), do AIS em tórax (0,68 vs 0,10), e do ISS (22,1 vs 4,22), bem como menor média de RTS (7,41 vs 7,78). Houve dois óbitos considerados como claramente evitáveis. No primeiro, uma vítima de trauma craniencefálico desenvolveu broncopneumonia após broncoaspiração. No segundo, houve obstrução da cânula orotraqueal por rolha em um doente com trauma torácico grave que desenvolveu encefalopatia anóxica.

Conclusão
Os óbitos em traumatizados com TRISS acima de 75% estão associados principalmente a idade avançada, trauma craniencefálico e trauma torácico grave, principalmente quando ocorrem infecções pulmonares na evolução.

RESUMO

Introdução
Ligas Acadêmicas são grupos formados e geridos por alunos da graduação sob supervisão e orientação de profi ssionais vinculados à Instituição de Ensino ou Hospitais. Além de aulas, cursos, atividades de pesquisa e assistência, é importante a inserção dos alunos na comunidade, por meio de atividades educativas, preventivas ou de promoção à saúde. A conscientização da população e profi ssionais acerca da magnitude da “doença trauma” é fundamental para que o atendimento prestado tenha cada vez mais qualidade e efi cácia e é este o papel de uma Liga do Trauma.

Relato de experiência
As atividades começaram com a fundação do serviço de atendimento ao trauma no Hospital do Trabalhador (HT). Os acadêmicos se reuniam informalmente para expandir as atividades para além do Pronto Socorro (PS), e há 10 anos se organizaram em uma Liga Acadêmica (LiAT), intensifi cando suas atividades. Foram organizadas campanhas de prevenção de acidentes, congressos, cursos de emergência, cursos de integração para acadêmicos do PS, além de 294 reuniões acadêmicas com aulas temáticas. A produção científi ca é marcante, tendo aproximadamente 90 apresentações de trabalhos em congressos e 15 publicações em revistas de cirurgia e de trauma, além de um manual para procedimentos em PS e um guia de bolso para acadêmicos.

Conclusão
A presença da LiAT ao longo da estruturação do PS-HT vem sendo fundamental para garantir um atendimento de qualidade às vítimas de trauma, realizar prevenção ampla aos acidentes de trânsito com conscientização da população e desenvolver atividades junto à comunidade.
Gunshot Wound to the Box: A Threat even on a Stable Patient
Authors: Ferrada Paula A , Parrish Dan W 
Published: October 2012

ABSTRACT

Context
Penetrating trauma to the thoracic cavity can result in immediate or delayed injuries to the heart. These injuries include among others contusion of the cardiac muscle, and laceration of the coronary arteries resulting on ischemia. Although, nonoperative management is a tempting option on a stable patient; close monitoring is guaranteed after this type of injury regardless of the initial vital signs.

Case report
We describe a case of a gunshot wound on a stable patient that was found to have blunt cardiac injury by the bullet. In the previous workup the missile appeared not to be penetrating the cardiac structures.

Conclusion
Awareness of this rare injury may provide a more rapid diagnosis, thereby preventing potentially catastrophic outcomes.

The Impact of perceived Corporate Social Responsibility (CSR) on Job Attitude and Performance of Internal Stakeholders
Authors: Iqbal Nadeem , Ahmad Naveed , Sheeraz Muhammad , Bashir Noman Ahmad 
Published: October 2012

Corporate social responsibility (CSR) has grown rapidly during last decade. Trend is showing that there is a significant increase of society’s overall concern about sustainable development with the aid of corporate social responsibility. The concept of sustainable development is gaining importance not only in scientific literature but also in board of governors room (BOG) of firms. Past researches have investigated the impact of CSR on employees but have been mostly focused on the analysis of the ‘external’ impact of CSR, considering the likely influence of CSR on prospective (rather than actual) employees, via mechanisms such as corporate image or corporate reputation (Blackhaus Stone and Heiner, 2002; Turban & Greening, 1997). The results of this study show that CSR has a significant effect on employees work attitudes and behaviors. CSR may possibly improve employees' attitudes and behaviors, contribute to corporations' achievement, and achieve a win-win state of affairs. Therefore, corporations should attach importance to CSR practice so as to benefit employees. Keywords: Sustainability, Corporate Social Responsibility, Employees, Job Attitude, Job Performance
Determinants of Pension Fund Investment in Nigeria: The Critical Factors
Authors: Olabode Adeoti, Johnson , Umar Gunu, , Emmanuel Tsado, 
Published: October 2012

Pension fund is a pool of resources contributed by the employees with the aim of having enough resources to carter for their needs after retirement. Therefore, pension fund needs to be invested so as to meet the aim of the contributors. This study was carried out to evaluate the factors that determine investment of Pension Funds. The study used primary data, which were generated by the use of questionnaire. Respondents were selected from a sample of five PFAs in Nigeria using simple random sampling technique. A total of 125 questionnaires were administered on 18 items using likert scales. Data collected were analyzed using factor analysis by principal component. Economic, Risk and Security of real estate factors were identified as the major determinants of pension fund investment. The study concludes that variables such as interest rate, internal control system etc, are not critical in determining investment of pension funds in Nigeria. The study also recommends that pension fund managers should develop good systems of mitigating on the enormous risks they face in their duty as investment managers.

Looking back while moving Forward: When teacher Attitudes Belie Teacher Motive in Bidialectal Classrooms
Authors: Denny Stacy 
Published: October 2012

Abstract: This study compares and contrasts the language attitudes of teachers of African American Vernacular English (AAVE) and West Indian Creole English (CE) speakers over the last fifty years, to determine if there have been any significant changes, to draw out the implications of these findings and offer reasons for the results. Teachers’ attitudes towards these languages were generally negative over the decades, but I noticed that as the number of teachers of colour increased in the USA, there was a slight shift in attitude towards AAVE in a positive direction. I conclude that though language attitudes are very difficult to change, teacher education which specifically targets and challenges teacher language attitudes will be a major step in helping to shift these attitudes further for the benefit of teacher and student.

Les « convulsions paroxystiques » de l’acteur. La synchronisation de l’image et du son sur le corps de Jerry Lewis
Authors: Cardinal Serge 
Published: October 2012

Fort de la conviction qu’un acteur peut participer à la création de possibilités esthétiques, l’auteur veut construire un concept de synchronisation qui inclue les tics de Jerry Lewis. Il s’agira d’un concept à trois composantes : chez Jerry Lewis, la synchronisation implique une opération de captation, une opération de dissonance, une opération de réfraction. Cette invention esthétique et poétique de l’acteur est en même temps création d’une possibilité de vie. À la fois occasion critique où s’évalue le rapport entre soi et les autres, seuil d’émergence d’une figure précaire d’humanité et de rythme existentiel qui compose une communauté éphémère, la synchronisation est chez Lewis une éthique ; capter, dissoner et réfracter sont les trois moments mis en boucle d’un même processus de subjectivation.
Face à l’idée de synchronisme. Notes d’un preneur de son sur le théâtre et le cinéma
Authors: Deshays Daniel 
Published: October 2012

Le point de synchronisme apparaît comme l’instant de vérité du cinéma. Il serait le lieu d’application de la loi, l’instant où image et son confondent le voir et l’entendre en une perception unique, un événement fusionné. Cet effet de réel construit après tant d’années de muet – la belle époque de l’asynchronisme – s’institue dans une production industrielle universelle du synchronisme, un nouveau monde reconstitué sous cette unique loi. Cette illusion est censée unir toutes les images et tous les sons sous une vérité indubitable, un modèle unique de représentation du monde. Cette belle loi invite bien sûr à la désobéissance.
Twinning‐, Polytypism‐, and Polarity‐Induced Morphological Modulation in Nonplanar Nanostructures with van der Waals Epitaxy
Authors: Utama Muhammad Iqbal Bakti , de la Mata Maria , Magen Cesar , Arbiol Jordi , Xiong Qihua 
Published: October 2012

AbstractTwinning, polytypism, and polarity are important aspects in nanostructural growth since their presence can affect various properties of the as‐grown products. The morphology of nanostructures grown via van der Waals epitaxy is shown to be strongly influenced by the twinning density and the presence of polytypism within the nanostructures, while the growth direction is driven by the compound polarity. With ZnTe as the model material, vertically aligned nanorods are successfully produced with variable cross‐section and branched crystals (tripods and tetrapods) on only a single type of substrate. Van der Waals epitaxy contributes by relaxing the lattice‐mismatch requirements for epitaxial growth and by enabling a variety of crystal planes in the initial stages of the growth to be interfaced to the substrate, regardless of the polarity of the epitaxial material. These results may provide more flexibility in tuning rationally the morphology of epitaxial nanostructures into other shapes with higher complexity by routine adjustment of growth environment.
Rhodium‐Catalyzed Oxidative ortho‐Acylation of Aryl Ketone O‐Methyl Oximes with Aryl and Alkyl Aldehydes
Authors: Yang Yaxi , Zhou Bing , Li Yuanchao 
Published: October 2012

AbstractThe rhodium‐catalyzed oxidative ortho‐acylation of aryl ketone O‐methyl oximes with aryl and alkyl aldehydes via CH bond activation is described. The cross‐coupling reaction exhibits high functional group tolerance and regioselectivity under relatively mild conditions and constitutes a versatile route to a diverse library of diaryl ketones, which are difficult to obtain by the classical Friedel–Crafts acylation. Moreover, this reaction proceeds via an unprecedented Rh‐catalyzed oxidative ortho‐acylation of aryl ketone O‐methyl oximes with highly electron‐deficient aryl aldehydes followed by a direct addition of the second ortho CH bond to aldehydes in a one‐pot reaction, to generate two CC bonds simultaneously.
Unintended effects of orphan product designation for rare neurological diseases

AbstractSince the introduction of the Orphan Drug Act in 1983, designed to promote development of treatments for rare diseases, at least 378 orphan drugs have been approved. Incentives include financial support, tax credits, and perhaps most importantly, extended market exclusivity. These incentives have encouraged industry interest and accelerated research on rare diseases, allowing patients with orphan diseases access to treatments. However, extended market exclusivity has been associated with unacceptably high drug costs, both for newly developed drugs and for drugs that were previously widely available. We suggest that a paradoxical effect of orphan product exclusivity can be reduced patient access to existing drugs. In addition, the costs of each new drug are arguably unsustainable for patients and for the American health care system. Of all the specialties, neurology has the third highest number of orphan product designations, and neurological diseases account for at least one‐fifth of rare diseases. Citing the use of tetrabenazine for chorea in Huntington disease, adrenocorticotropic hormone for infantile spasms, and enzyme replacement therapy with alglucosidase alpha for Pompe disease, we highlight these paradoxical effects.

Auditory cortical function during verbal episodic memory encoding in Alzheimer's disease
Authors: Dhanjal Novraj S. , Warren Jane E. , Patel Maneesh C. , Wise Richard J. S. 
Published: October 2012

ObjectiveEpisodic memory encoding of a verbal message depends upon initial registration, which requires sustained auditory attention followed by deep semantic processing of the message. Motivated by previous data demonstrating modulation of auditory cortical activity during sustained attention to auditory stimuli, we investigated the response of the human auditory cortex during encoding of sentences to episodic memory. Subsequently, we investigated this response in patients with mild cognitive impairment (MCI) and probable Alzheimer's disease (pAD).MethodsUsing functional magnetic resonance imaging, 31 healthy participants were studied. The response in 18 MCI and 18 pAD patients was then determined, and compared to 18 matched healthy controls. Subjects heard factual sentences, and subsequent retrieval performance indicated successful registration and episodic encoding.ResultsThe healthy subjects demonstrated that suppression of auditory cortical responses was related to greater success in encoding heard sentences; and that this was also associated with greater activity in the semantic system. In contrast, there was reduced auditory cortical suppression in patients with MCI, and absence of suppression in pAD. Administration of a central cholinesterase inhibitor (ChI) partially restored the suppression in patients with pAD, and this was associated with an improvement in verbal memory.InterpretationVerbal episodic memory impairment in AD is associated with altered auditory cortical function, reversible with a ChI. Although these results may indicate the direct influence of pathology in auditory cortex, they are also likely to indicate a partially reversible impairment of feedback from neocortical systems responsible for sustained attention and semantic processing.

Published: October 2012

ObjectiveMyasthenia gravis (MG) is an autoimmune disease mediated mainly by anti–acetylcholine receptor (AChR) antibodies. The thymus plays a primary role in MG pathogenesis. As we recently showed an inflammatory and antiviral signature in MG thymuses, we investigated whether pathogen‐sensing molecules could contribute to an anti‐AChR response.MethodsWe studied the effects of toll‐like receptor agonists on the expression of α‐AChR and various tissue‐specific antigens (TSAs) in human thymic epithelial cell (TEC) cultures. As polyinosinic–polycytidylic acid (poly[I:C]), which mimics double‐stranded RNA (dsRNA), stimulated specifically α‐AChR expression, the signaling pathways involved were investigated. In parallel, we analyzed the expression of dsRNA‐signaling components in the thymus of MG patients, and the relevance of our data was investigated in vivo in poly(I:C)‐injected mice.ResultsWe demonstrate that dsRNA signaling induced by poly(I:C) specifically triggers the overexpression of α‐AChR in TECs and not of other TSAs. A poly(I:C) effect was also observed on MG TECs. This induction is mediated through toll‐like receptor 3 (TLR3) and protein kinase R (PKR), and by the release of interferon (IFN)‐β. In parallel, human MG thymuses also display an overexpression of TLR3, PKR, and IFN‐β. In addition, poly(I:C) injections specifically increase thymic expression of α‐AChR in wild‐type mice, but not in IFN‐I receptor knockout mice. These injections also lead to an anti‐AChR autoimmune response characterized by a significant production of serum anti‐AChR antibodies and a specific proliferation of B cells.InterpretationBecause anti‐AChR antibodies are highly specific for MG and are pathogenic, dsRNA‐signaling activation could contribute to the etiology of MG.

AbstractNanoplasmonic biosensors based on gold nanoparticle functionalized smooth silica and porous calcium carbonate particles are presented. It is identified in this comparative study the role of porosity for adsorbing gold nanoparticles and subsequent detection of biomarkers. That is further applied in this study for detection of biomarkers. Detection of glucose – a biomarker of diabetes is studied together with that of bovine serum albumin – a very relevant bio‐molecule. Raman scattering is used for label‐free detection of molecules in the sub‐µM–mM range detection capabilities, which covers the range corresponding to healthy and diseased persons. Implications of current study for detection and identification of biomarkers are discussed.
