Diffusion of the utopias. The academy and the media in times of pandemic

At the end of the 20th century, the disappearance of the great utopias occurs. Crises are favorable moments to imagine better worlds. Social scientists and humanists - because of their knowledge of reality and its possibilities for change - are privileged to visualize the Covid-19 crisis as an opportunity for change and transfer the orientation of change to all of society. This is a transcendental translation for the consolidation of utopia in the social imaginary. This work explores the rehabilitation of utopia in the exceptional circumstances of the pandemic's start by academics. Doing this identifies, classifies, and analyzes the specific proposals that these thinkers have published in the press to move towards a happy world. We note that the pandemic has not managed to rehabilitate the utopia and that the community's proposals for change are fragmented. We consider that this fragmentation is a symptom of micro-stories, which implies a shift towards micro-routes. However, medium-range utopias proliferate in which messages appear insistently and, in that sense, may be reflected in the social imaginar

Diagnóstico molecular de tuberculosis pélvica: reporte de caso

Tuberculosis is a re-emerging infectious disease. A retrospective analysis was made of the clinical history of a 48-year-old woman in April 2009; she was a secretary at a third-level hospital living in an urban area. Pelvic tubercular infection was suggested as a possible diagnosis; spoligotyping molecular methodology was used on a peritoneal secretion sample to confirm such diagnosis and confirmed the presence of Mycobacterium tuberculosis (octal code 777777777760771, SIT 53, Family T1)

Micobacteriosis diseminada con compromiso de válvula aórtica protésica: primer caso de Mycobacterium peregrinum de tipo III reportada en Colombia

Rapidly growing mycobacteria are non-tuberculous mycobacteria amply present in the environment. Although they are not usually pathogenic for humans, they are opportunistic in that they can cause disease in people with disadvantageous conditions or who are immunocompromised. Mycobacterium peregrinum, an opportunistic, rapidly growing mycobacteria, belongs to the M. fortuitum group and has been reported as responsible for human cases of mycobacteriosis.A case of M. peregrinum type III is herein reported as the first in Colombia. It presented as a disseminated disease involving a prosthetic aortic valve (endocarditis) in a seventeen-year-old girl with a well-established diagnosis of prosthetic aortic valve endocarditis who was referred for a surgical replacement. Due to a congenital heart disease (subaortic stenosis with valve insufficiency), she had two previous aortic valve implantation surgeries. One year after the second implantation, the patient presented with respiratory symptoms and weight lost indicative of lung tuberculosis.A chest X-ray did not show parenchymal compromise but several Ziehl-Neelsen stains were positive. An echocardiography showed a vegetation on the prosthetic aortic valve. In blood and sputum samples, M. peregrinum type III was identified through culture, biochemical tests and hsp65 gene molecular analysis (PRA). The patient underwent a valve replacement and received a multidrug antimycobacterial treatment. Progressive recovery ensued and further samples from respiratory tract and blood were negative for mycobacteria.Mycobacterium preregrinum es una micobacteria de rápido crecimiento perteneciente al complejo fortuitum que ha sido reportado como responsable de casos de micobacteriosis en humanos.Se presenta el caso de una micobacteriosis por M. peregrinum de tipo III, el primero reportado en Colombia, en una paciente de 17 años de edad con una endocarditis de una válvula aórtica protésica, implantada inicialmente por estenosis subaórtica congénita con insuficiencia y, posteriormente, por estenosis aórtica relacionada con la válvula inicialmente implantada. Un año después del segundo implante, presentó sintomas respiratorios y pérdida de peso sugestivos de tuberculosis pulmonar.Las coloraciones de Ziehl-Neelsen del esputo fueron positivas aunque la radiografía de tórax no mostró compromiso del parénquima. En el ecocardiograma se encontró una vegetación en la válvula aórtica. En las muestras de sangre y de esputo, se identificó M. peregrinum de tipo III por cultivo, pruebas bioquímicas y análisis molecular del gen hsp65 por PCR-restriction pattern analysis (PRA).La paciente se sometió a cambio de válvula y recibió tratamiento combinado contra la micobacteria, con rápida recuperación. Las muestras tomadas del sistema respiratorio y sanguíneo se tornaron negativas para micobacterias.Las micobacterias de rápido crecimiento son microorganismos pertenecientes a las micobacterias no tuberculosas que tienen amplia distribución ambiental. Aunque usualmente no son patógenas para los humanos, en condiciones desfavorables, pueden causar enfermedad en la población general o en huéspedes inmunocomprometidos, por lo cual se consideran oportunistas
