Espondilitis tuberculosa no es una metástasis vertebral: diagnóstico diferencial y tratamiento quirúrgico. A propósito de un caso

Presentamos el caso de una paciente con dorsalgia y clínica neurológica de varios meses de evolución que ante las pruebas de imagen fue erróneamente diagnosticada de metástasis vertebral sin confirmación previa con biopsia. El deterioro progresivo neurológico y las nuevas pruebas de imagen confirmaron el diagnóstico de tuberculosis vertebral. La paciente fue tratada mediante curetaje, desbridamiento, fusión intersomática y osteosíntesis anterior además del tratamiento médico. Hubo una recuperación neurológica de la función sensitiva, motora y esfinteriana prácticamente completa al mes de la intervención. Tras 20 meses de evolución la paciente está asintomática sin evidencia de progresión de la enfermedadWe report a patient with back pain and neurological symptoms several months of evolution to the test image was wrongly diagnosed with spinal metastases without prior confirmation with biopsy. The progressive deterioration of neurological and new imaging confirmed the diagnosis of spinal tuberculosis. The patient was treated by curettage, debridement, anterior interbody fusion and internal fixation in addition to medical treatment. There neurological recovery of sensory function, motor and sphincter almost complete month after the intervention. After 20 months of evolution, the patient is asymptomatic without evidence of disease progressio

Hidatidosis ósea: nuestra casuística

Se revisan los resultados de 16 casos de hidatidosis musculoesquelética tratados en la Unidad de Sépticos del Aparato Locomotor del Hospital Universitario "La Fe" de Valencia en el período 1972-1989. Las dificultades diagnósticas fueron importantes, siendo en 5 de los casos un diagnóstico operatorio. Analizados los métodos de tratamiento se llega a la conclusión de que la curación definitiva sólo se consigue con la resección completa y amplia de la lesión. Los curetajes, acompañados o no de aseptizaciones químicas, suelen dar recidivas. Se recomienda combinar el tratamiento médico con el quirúrgico.The results of 16 cases of musculoskeletal hydatidosis treated in the locomotive Apparatus Septic Unit of the Valencia University Hospital "La Fe" between 1972 and 1989 wer e reviewed. The diagnostic difficulties wer e marked and 5 cases wer e diagnosed at surgery. After analyzing the therapeutical approaches, it is drawn the conclusion that a definitive healing is achieved only when an extensive and complete resection is done. Curettage, with and without chemical aseptization, generally results in recurrence. A combined medical and surgical treatment is recommended

Convergence calls: multimedia storytelling at British news websites

This article uses qualitative interviews with senior editors and managers from a selection of the UK's national online news providers to describe and analyse their current experimentation with multimedia and video storytelling. The results show that, in a period of declining newspaper readership and TV news viewing, editors are keen to embrace new technologies, which are seen as being part of the future of news. At the same time, text is still reported to be the cornerstone for news websites, leading to changes in the grammar and function of news video when used online. The economic rationale for convergence is examined and the article investigates the partnerships sites have entered into in order to be able to serve their audience with video content. In-house video is complementing syndicated content, and the authors examine the resulting developments in newsroom training and recruitment practices. The article provides journalism and interactive media scholars with case studies on the changes taking place in newsrooms as a result of the shift towards multimedia, multiplatform news consumption

Dealing with the mess (we made): Unraveling hybridity, normativity, and complexity in journalism studies

In this article, we discuss the rise and use of the concept of hybridity in journalism studies. Hybridity afforded a meaningful intervention in a discipline that had the tendency to focus on a stabilized and homogeneous understanding of the field. Nonetheless, we now need to reconsider its deployment, as it only partially allows us to address and understand the developments in journalism. We argue that if scholarship is to move forward in a productive manner, we need, rather than denote everything that is complex as hybrid, to develop new approaches to our object of study. Ultimately, this is an open invitation to the field to adopt experientialist, practice-based approaches that help us overcome the ultimately limited binary dualities that have long governed our theoretical and empirical work in the field

Citizen participation in news

The process of producing news has changed significantly due to the advent of the Web, which has enabled the increasing involvement of citizens in news production. This trend has been given many names, including participatory journalism, produsage, and crowd-sourced journalism, but these terms are ambiguous and have been applied inconsistently, making comparison of news systems difficult. In particular, it is problematic to distinguish the levels of citizen involvement, and therefore the extent to which news production has genuinely been opened up. In this paper we perform an analysis of 32 online news systems, comparing them in terms of how much power they give to citizens at each stage of the news production process. Our analysis reveals a diverse landscape of news systems and shows that they defy simplistic categorisation, but it also provides the means to compare different approaches in a systematic and meaningful way. We combine this with four case studies of individual stories to explore the ways that news stories can move and evolve across this landscape. Our conclusions are that online news systems are complex and interdependent, and that most do not involve citizens to the extent that the terms used to describe them imply

Influencia del origen del haba sobre el valor nutricional de la harina de soja

La harina de soja (HS) es la principal fuente de proteína en piensos para animales monogástricos. La mayor parte de las HS utilizadas en Europa proceden del continente Americano, en particular de Argentina (ARG), Brasil (BRA) y Estados Unidos (USA). Aunque la composición y valor nutricional de las HS varía entre países de origen (Grieshop et al., 2003; De Coca et al., 2008; 2010; Valencia et al., 2008), las tablas de composición de alimentos (NRC, 1998; FEDNA, 2010) clasifican las HS en función de su contenido en PB, sin tener en cuenta ni el origen ni las condiciones del procesado. En un trabajo anterior Mateos et al. (2009) se presentaron los resultados obtenidos de una colección de 262 muestras de HS recolectadas en las cosechas de los años 2007 y 2008 procedentes de estos tres países. Dependiendo de la variable considerada, el número de muestras analizadas varió entre 50 y 262. El presente trabajo tuvo como objetivo completar los análisis y complementar los resultados anteriores en relación con la composición química, el valor nutricional y la calidad de la PB de la HS con nuevas muestras procedentes de las cosechas de los años 2009 y 2010

THE ACCUSED IS ENTERING THE COURTROOM: THE LIVE-TWEETING OF A MURDER TRIAL.

© 2017 Informa UK Limited, trading as Taylor & Francis GroupThe use of social media is now widely accepted within journalism as an outlet for news information. Live tweeting of unfolding events is standard practice. In March 2014, Oscar Pistorius went on trial in the Gauteng High Court for murder. Hundreds of journalists present began live-tweeting coverage, an unprecedented combination of international interest, permission to use technology and access which resulted in massive streams of consciousness reports of events as they unfolded. Based on a corpus of Twitter feeds of twenty-four journalists covering the trial, this study analyses the content and strategies of these feeds in order to present an understanding of how microblogging is used as a live reporting tool. This study shows the development of standardised language and strategies in reporting on Twitter, concluding that journalists adopt a narrow range of approaches, with no significant variation in terms of gender, location, or medium. This is in contrast to earlier studies in the field (Awad, 2006, Hedman, 2015; Kothari, 2010; Lariscy, Avery, Sweetser, & Howes, 2009 Lasorsa, 2012; Lasorsa, Lewis, & Holton, 2011; Sigal, 1999, Vis, 2013).Peer reviewe

Differences among origins on nutritional and quality parameters of soybean meal

Soybean meal (SBM) is the main protein source in livestock feeds. United States (USA), Brazil (BRA), and Argentine (ARG) are the major SBM exporter countries. The nutritive value of SBM varies because genetics, environment, farming conditions, and processing of the beans influence strongly the content and availability of major nutrients. The present research was conducted to determine the influence of origin (USA, BRA and ARG) on nutritive value and protein quality of SBM

Association of increased fibrinogen concentration with impaired activation of anticoagulant protein C

BACKGROUND: Low levels of activated protein C (APC) are a risk factor for venous thrombosis. The mechanisms leading to interindividual differences in APC are not totally elucidated. Protein C is activated by the thrombin-thrombomodulin complex. As thrombin binds to fibrinogen and thrombomodulin through a common region, it is conceivable that fibrinogen influences the activation of protein C. This would help to explain the association between high levels of fibrinogen and an increased thrombotic risk. METHODS: We analyzed the association between circulating APC levels and fibrinogen concentration in 382 healthy subjects. Subsequently, we studied the effect of increasing fibrinogen concentrations on the APC generation on cultured endothelial cells. RESULTS: An independent inverse association between circulating APC levels and fibrinogen was found [betacoefficient, -0.16; 95% confidence interval (95% CI) -0.26, -0.06; P = 0.001]. For each 100 mg dL(-1) increase in fibrinogen, the independent risk of having low APC levels (<0.7 ng mL(-1)) was almost three times higher (OR 2.8; 95% CI 1.1, 7.2; P = 0.04). Accordingly, a notable association between increasing fibrinogen concentrations and the reduction in the thrombin-thrombomodulin dependent activation of protein C on endothelial cells was found (r = -0.57; P = 0.002). CONCLUSIONS: We present evidence of an inverse association between circulating APC and fibrinogen levels. According to this finding together with the results of our in vitro experiments, we propose that the impairment in the generation of APC on endothelial cells constitutes a new prothrombotic mechanism of fibrinogen
