ABSTRACT

The plague is an infectious disease that has transcended through history and has been responsible for three pandemics with high mortality rates. During the third pandemic that started in Hong Kong (1894), the disease spread through maritime routes to different regions in the world, including South America. In this region, approximately 16 million people are thought to be at risk in relation to this disease due to specific situations like human-rodent coexistence inside houses in rural areas, homes built with inadequate materials that are vulnerable to invasion by these animals, inappropriate storage of crops and an increase in rainfall and deforestation, which allows for the displacement of wild fauna and man invasion of the natural foci of the disease. Between 1994 and 1999, five countries: Bolivia, Brazil, Ecuador, Peru and the United States of America, reported approximately 1,700 cases with 79 related deaths. In Colombia we have historical data about an "infectious pneumonia" with high mortality rates that occurred during the same months, for three consecutive years (1913 to 1915) in the departments of Magdalena, Atlántico and Bolívar, located in the Colombian Atlantic coast, which suggested plague, but could not be confirmed.

ABSTRACT

Antecedentes. La acondroplasia es la más común de las displasias esqueléticas. Se trata de una enfermedad autosómica dominante con penetrancia completa. Esta enfermedad se debe a una mutación en el gen del receptor 3 del factor de crecimiento fibroblástico (FGFR3). El 90% o más de los casos se deben a mutaciones nuevas que se originan en las células germinales de padres sanos, asociada a una edad incrementada. Se ha calculado una frecuencia al nacimiento de 1:10.000 a 1:30.000. En la mayoría de los casos (97%) la mutación presente es la transición G1138A, en el dominio transmembranal de gen. En el resto se presenta la transversión en el mismo nucleótido, G1138C. Objetivo. Detectar mutaciones del gen FGFR3 en un grupo de pacientes colombianos con acondroplasia. Material y métodos. Estudiamos un grupo de 20 pacientes con diagnóstico clínico de acondroplasia. Se utilizó el método, ARMS-PCR (Amplification Refractory Mutation System - Polymerase Chain Reaction) que emplea dos pares primers diseñados específicamente para amplificar respectivamente los dos diferentes nucleótidos de una mutación puntual. Resultados. 19 pacientes (95%), presentaron la mutación G1138A y un paciente presentó la mutación G1138C (5%). Conclusión. No obstante la acondroplasia presentar un fenotipo considerado distinguible de otras displasias esqueléticas, algunas veces la hipocondroplasia, que se presenta por mutaciones en el mismo gen FGFR3, puede ser difícil de discriminar clínicamente, por lo que el análisis mutacional permite la correcta clasificación, así como de eventualmente otras displasias esqueléticas por mutaciones en otros genes.

ABSTRACT

The mummy studied belonged to the prehispanic Guane society. According to the Mom 003 record of the Archaeological Museum of the House of the Marqués de San Jorge, it was found in a cave in the department of Santander, Colombia, and was donated to the Culture Promotion Fund of the Banco Popular more than 30 years ago. The gender of the mummy had been previously determined by PCR study of the Y chromosome; computerized tomography studies (CT) were carried out and samples of lung tissue, vertebral spine and skin were taken for studying tuberculosis. The CT scans clearly show the presence of spinal tuberculosis, accounting for its important angular cifosis or Pott's disease. DNA obtained from lung tissue was submitted to ribotyping with genes of the 16S ribosomal subunit, giving positive results. This finding demonstrates the presence of tuberculosis in prehispanic Colombia.

ABSTRACT

Con una perspectiva histórica se analiza la actual guerra en Colombia. El esfuerzo de guerra que mantienen contra el Estado y el pueblo colombiano las guerrillas y las autodefensas ilegales, y que se sostiene con el negocio del narcotráfico, al haber generado grandes problemas sanitarios, ambientales y de derechos humanos es insostenible, a la luz de una política fundada en la antropología y la bioética. La debilidad y la poca presencia del Estado en muchas regiones del país favorecen las crisis sanitarias, ambientales y de derechos humanos
