Cryptococcosis in Atlántico, Colombia: an approximation of the prevalence of this mycosis and the distribution of the etiological agent in the environment

ABSTRACTINTRODUCTION:Cryptococcosis is an invasive disease acquired by inhalation of infectious propagules from the environment. Currently, compulsory notification of the spread of this disease is not required in Colombia. However, reporting of human immunodeficiency virus (HIV)/acquired immune deficiency syndrome cases to the National Surveillance System has suggested that there is a growing population at risk of contracting cryptococcosis. Few studies have described the occurrence of cryptococcosis in Colombia. Therefore, in this study, we examined the pathology of this disease in Atlántico, Colombia and determined the distributions of Cryptococcus neoformans and Cryptococcus gattii in the environment.METHODS:Clinical samples/isolates were gathered from cases of cryptococcosis previously diagnosed at health institutions in Atlántico, and surveys were completed by clinicians. The environmental study considered 32 sampling points and three tree species, i.e., Quickstick ( Gliricidia sepium ), Almond ( Terminalia catappa ), and Pink trumpet ( Tabebuia rosea ). Environmental and clinical samples/isolates were analyzed for phenotypic and genotypic confirmation.RESULTS:From 1997-2014, 41 cases of cryptococcosis were reported. The mean patient age was 40.5 years (range: 18-63 years); 76% were men, and 78% were HIV positive. Isolation was possible in 38 cases ( C. neoformans , molecular type VNI in 37 cases and C. gattii , molecular type VGI in one case). In 2012-2014, 2,068 environmental samples were analyzed with a positivity of 0.4% ( C. neoformans , molecular type VNI) in Almond and Pink trumpet trees.CONCLUSIONS:Cryptococcus neoformans , molecular type VNI had a higher prevalence than C. gattii and was associated with human exposure and the pathogenesis of cryptococcosis in this geographical region.

Medición del nivel de orientación empática en alumnos de facultades o carreras de odontología de Argentina, Chile, Colombia, Costa Rica, Panamá y Perú.

Las investigaciones, tanto a nivel médico como odontológico, indican que la empatía ha estado relacionada, teóricamente o empíricamente, a diversos atributos, tales como el comportamiento prosocial, habilidad para recabar la historia clínica, aumento del grado de satisfacción del paciente y del médico, mejores relaciones terapéuticas y buenos resultados clínicos. El objetivo del proyecto es determinar y describir el nivel de empatía de los alumnos que cursan Odontología de algunas Universidades de Latinoamericana, según el nivel de enseñanza y el género. Esta investigación corresponde a un estudio no experimental y de carácter exploratorio. Este tipo de diseño es transversal, descriptivo y ex post facto causa y efecto (potencialmente correlacional). Este proyecto dará origen a un trabajo que se especializará en recolectar datos en un momento temporal determinado para describir en él las variables que se estudiarán, y analizar su comportamiento y posibles asociaciones existentes entre estas variables. La población comprende a los estudiantes pertenecientes a los niveles 1º a 5º de la carrera de Odontología de cada una de las Facultades o Carreras comprometidas en el estudio. La unidad de análisis es el sujeto estudiante de cada nivel antes señalado y en cada una de las poblaciones estudiadas. Se aplicará la Escala de Empatía Médica de Jefferson a todos los estudiantes comprometidos en este estudio, previa explicación detallada de los propósitos de esta investigación y de los objetivos de la misma, incluyendo su carácter confidencial.
