ABSTRACT
Objetivo: Determinar la relación entre la angiografía por tomografía computada (angio-TC) coronaria y el desarrollo de un evento coronario agudo en los primeros 6 meses en pacientes adultos con dolor torácico agudo, atendidos en el servicio de urgencias de una clínica de nivel iv de atención. Materiales y métodos: Entre febrero de 2012 y de 2014, se realizó un estudio descriptivo y retrospectivo en pacientes adultos que consultaron al servicio de urgencias por un dolor torácico agudo. Todos (n = 62) fueron estudiados por angio-TC coronaria en un tomógrafo Siemens de 40 detectores. Del total, se incluyeron para el análisis a 46 pacientes con resultado negativo o estenosis menor del 50%, a los que se les realizó un seguimiento telefónico o por historia clínica de 6 meses de duración. Se excluyeron los casos a los que no se les pudo hacer un control en los 6 meses posteriores o que tuvieron una estenosis mayor del 50%. Resultados: En la angio-TC se encontraron coronarias sanas en 37 (80%) pacientes y placas no obstructivas en 9 (20%). De los 46 casos incluidos, ninguno presentó un evento coronario agudo o muerte secundaria a este durante los 6 meses de seguimiento. Conclusión: La angio-TC coronaria es una ayuda diagnóstica útil para la valoración de pacientes con dolor torácico agudo. Constituye una herramienta segura y de rápida realización, que permite definir los resultados negativos o la existencia de placas no obstructivas desde el mismo servicio de urgencias
Objective: To determine the relationship between the results of coronary computed tomography (CT) angiography and the development of acute coronary events during the first six months of following in adult patients with acute chest pain seen in the emergency department of an iv level hospital. Materials and methods: A retrospective and descriptive study was conducted that included patients with chest pain that were seen in the emergency department, between February 2012 and February 2014. All of them (n = 62) underwent coronary CT angiography in a 40 detector Siemens CT scanner. The 46 patients who had a negative result or a non-obstructive plaque were included in the analysis, and were followed up over 6 months through medical records or by telephone. Patients who were not able to be tracked during the 6 months, or who had a coronary obstructive plaque greater than 50%, were excluded. Results: Coronary CT angiography was performed on 46 patients, finding healthy coronary arteries in 37 (80%) cases and non-obstructive plaques in 9 (20%). There were no acute coronary events or deaths secondary to this during the follow-up period of 6 months. Conclusión: Coronary CT angiography is a useful diagnostic aid for the evaluation of patients with acute chest pain. It is a safe tool and rapid to perform, which allows defining negative results or the existence of a non-obstructive plaque in the emergency department itself.

An acute clinical picture of variable intensity may occur during the initial primary phase of HIV infection, it may however pass unnoticed. We report 12 seronegative subjects (11 male homosexuals, 1 female heterosexual, aged 18 to 44 years old), that sembling an acute clinical picture preceding seroconversion. All had a sudden beginning, reduration were variable, lasting a mean of 14 (range 5-44) days an remaining asymptomatic thereafter. Most patients presented a discrete leukopenia with lymphopenia at the expense of CD4 lymphocytes, followed by an absolute lymphocytosis in some, with an increase in CD8 lymphocytes. All became positive for HIV; circulating HIV antigen was identified in 3 and IgM anti-HIV antibodies were detected during the symptomatic period by third generation ELISA in other 3. It is concluded that the clinical picture of primary HIV infection has identificable clinical serological and immunological features and its recognition has diagnostic and preventive implications

The earth of ornamental plants is one of the main reservoirs of Aspergillus type of fungi in hospital areas. We studied 174 ornamental interior plants from a hospital at Santiago. Samples were obtained from the soil surface and sowed in Sabouraud-glucose agar, adding streptomycin and G-penicillin. After 72 h of culture, at least one strain of Aspergillus was isolated from 140 samples (80.5 percent). The most frequently isolated strain was A fumigatus (129 samples), followed by A miger (75 samples). A fumigatus and A niger were the only isolated strains in 65 and 11 samples respectively. These findings confirm that ornamental plants can be important reservoirs of Aspergillus strains, a potential infectious agent for immunocompromised patients in hospital areas
