The 2011 student movement on the Chilean press: What Pluralism in the digital press?

This article presents results of two research projects that explored the coverage of the Student Movement 2011 carried out by two chains of newspaper of Chile: El Mercurio S.A.P and Diarios Mi Voz, in three regions of the country. These press chains correspond to paper and digital press, respectively. In this research, we analyze information and photographs allowed to establish changes in journalistic practices as well as similarities in the ways of representing the student movement.

Pérdida de la biomasa en Eucalyptus camaldulenses dehnh en el proceso de campo, patio de acopio y astillero en el Ingenio San Antonio, Chinandega.

En los años 80 se creó dentro en el Ingenio San Antonio el Proyecto Forestal, en el municipio de Chichigalpa, departamento de Chinandega; y es así como inician las primeras actividades de producir madera de Eucalipto camaldulenses Dehnh. Actualmente en el Proyecto Forestal del Ingenio San Antonio, se carece de datos cuantitativos que representen porcentualmente la pérdida de biomasa que sufre la madera en el lapso de tiempo desde su corta, hasta su fundición en las calderas. El propósito de este estudio es proveer información de las cantidades de biomasa que se pierde en la madera de Eucaliptus camaldulenses Dehnh desde la etapa de corta en la plantación, hasta el patio de acopio y astilladora del Ingenio. En este estudio se establecieron parcelas de 20 m x 10 m (200 m2) dispersas en el lote próximo a aprovechamiento; dentro de estas parcelas se establecieron parcelas útiles de 16 m x 8 m (128 m2), abarcando un total de 8 árboles y seleccionar 2 árboles para seccionarlos en: Follaje, ramas grandes, ramas pequeñas, fuste y sistema radicular, de cada uno se obtuvo el peso verde, se extrajeron muestras de 500 gr de cada sección, con el fin de determinar el contenido de biomasa seca de la madera de Eucaliptus camaldulenses Dehnh. Se pretendió de igual manera, a través de mediciones de peso a los 5, 10, y 20 días evaluar la pérdida de humedad que experimenta la madera durante 20 días que es depositada en el patio de acopio y con el análisis del peso de las trozas después de los 20 días y el peso de los residuos de estas, determinar en contenido de biomasa perdida en la astilladora. En este estudio se encontró que el contenido de biomasa total en promedio sumando el follaje, ramas grandes, ramas pequeñas, fuste y sistema radicular de los árboles estudiados en la plantación fue de 0.07040 ton, lo que equivale a (0.19556 ton/ha). En promedio la pérdida de humedad que sufren las trozas a la entrada al patio de acopio a los veinte días es de 24.59 kg (0.02459 ton), lo que equivale a 28.90 % del peso original de cada troza. La pérdida de biomasa en el astillado, en promedio se encontró que fue de 2 kg (0.002 ton), en porcentaje de biomasa equivale a 5.43 % del peso original.

Iatrogenic Cushing’s syndrome and Secondary Adrenal Insufficiency in an HIV Patientreceiving Fluticasone and Ritonavir

Objectives: To illustrate that the protease inhibitor (PI) ritonavir, widely used as part of the treatment for HIV, might cause drug–drug interactions with inhaled corticosteroids. Material and methods: A case report is presented. Results: An HIV-positive patient presented with gradually changing body composition that was ascribed to lipodystrophy. Finally, iatrogenic Cushing's syndrome with secondary adrenal insufficiency was diagnosed due to a drug–drug interaction of ritonavir and fluticasone. Conclusion: Lipodystrophy might mimic Cushing's syndrome. The combination of ritonavir and inhaled fluticasone may lead to systemic steroid excess causing Cushing's syndrome and secondary adrenal insufficiency.

Immunologic Storm Simulating Systemic Lupus Erythematosus Following Parvovirus B19 Infection

Background: The appearance of symptoms compatible with systemic autoimmune diseases has been described in relation to several viral infections like HIV, cytomegalovirus and especially PVB19, depending on the evolution of the immunological condition of the host and their age. We present a young immunocompetent male patient, with clinical manifestations simulating systemic lupus erythematosus (SLE) with important activation of cytokines. Methods: For quantification of the different cytokines in plasma, a commercially available multiplex bead immunoassay, based on the Luminex platform (Cat # HSCYTO-60SK-08, Milliplex® MAP High Sensitivity, Millipore), was used according to the manufacturer’s instructions. All samples were run in duplicate and the data (mean fluorescence intensity) were analyzed using a Luminex reader. The mean concentration was calculated using a standard curve. Results: The clinical evolution was favourable without the need for any specific treatment, showing complete recovery after two months. Whilst the symptoms and viral charge were disappearing, the anti-DNA continued to increase and we demonstrate important activation of IL-10, IL-6 and TNFα cytokines as a result of a hyperstimulating response by an immunocompetent hyperfunctional system, which persists after clinical improvement. We should emphasize the behaviour of two cytokines: IL-12p70 and IL-2, which showed opposite tendencies. Conclusions: Viral infections, especially PVB19, can produce or simulate several autoimmune diseases as a hyperstimulation response from an immunocompetent hyperfunctional system. Consequently, a persistent increase of autoantobodies and important activation of cytokines, even after clinical improvement and seroconversion, can be demonstrated.

Brucella Non-Neutrocytic Bacterascites in a Patient with Chronic Liver Disease

Objectives: To report a case of Brucella peritonitis. Patient and methods: We describe the case of a patient and present a brief review of the few published reports. Results: The patient had alcoholic cirrhosis of the liver and was diagnosed with Brucella non-neutrocytic bacterascites. Conclusion: Brucellosis is a common zoonosis with worldwide distribution. It is a systemic disease with the potential to predominantly affect one organ or a specific system (focal brucellosis). However, peritoneal focalization of this disease is a very rare presentation.

Successful Treatment Using Simeprevir, Sofosbuvir and Rituximab of a Severe Form of Hepatitis C Virus-related Mixed Cryoglobulinemia with Cardiac Involvement

Numerous extrahepatic manifestations have been reported in hepatitis C virus (HCV) infection, particularly mixed cryoglobulinemia (MC). MC generally responds to clearance of HCV under pegylated-interferon plus ribavirin treatment. New direct-acting antiviral agents have been licensed for HCV under different combinations but have not been studied in severe forms of MC. Here, we present a case report describing a life-threatening form of MC with multivisceral involvement, which was successfully treated with concomitant rituximab, sofosbuvir and simeprevir. In light of the rapid clinical remission associated with sustained virological response and the excellent side-effect profile, this treatment should be considered as a first-line therapy in severe forms of MC.
