Endocrinología y epistemología: el eje hipotálamo-hipófisis-ovario revisitado
Henao,Guillermo;
Revista Colombiana de Obstetricia y Ginecología , 2004,
Abstract: history of the discovery of the hypothalamic-pituitary-ovarian axis and its role in nervous, endocrine and reproductive systems is related to conceptions about the existence of subtle substances formerly named animal spirits and recently as hormones, neurotransmitters, and others. this research usually follows a lineal series model, a?b type, according to the ?one cause, one effect? principle. nevertheless, its discovery was performed in a contrary sense, ?effect-cause?. this scheme was broken for another discoveries: hormone feed-back -one effect may acts on its own cause-, and multiple factors, including outside the system, have a random influence. therefore, there are superpositions between exocrine, endocrine, immunologic and nervous systems and its traditional limits may don?t appear. so, diagnostic and therapeutic methods may be insufficient for its purposes. there are practical consequences related to treatment and ethics in medical exercise.
Endocrinología y epistemología: el eje hipotálamo-hipófisis-ovario revisitado Epistemology and endocrinology: the hypothalamic-hypophysis-ovary axis revisited
Guillermo Henao
Revista Colombiana de Obstetricia y Ginecología , 2004,
Abstract: La historia del descubrimiento del eje hipotálamo-hipófisis-ovario y su papel en los sistemas nervioso, endocrino y reproductivo se correlaciona con las concepciones sobre la existencia de sutiles sustancias en un comienzo denominadas espíritus animales y recientemente con diversos nombres, entre ellos hormonas y neurotransmisores. Se ha seguido un modelo de serie lineal A...B, acorde con el principio una causa, un efecto , si bien su descubrimiento fue al contrario, efecto, causa . El esquema se rompió con los descubrimientos de la retroacción hormonal, en la cual el efecto puede convertirse en causa, y la participación aleatoria de múltiples factores externos al eje, unos internos al organismo, otros externos a él. Hay superposición entre los sistemas exocrino, endocrino, inmunológico y nervioso, de tal manera que en ciertos momentos se borran los tradicionales límites entre ellos, por lo cual las interdependencias pueden sobrepasar la capacidad de los métodos diagnósticos y terapéuticos en uso. Esto tiene consecuencias prácticas no solo terapéuticas sino también éticas, por lo que se requiere precaución en el acto médico.

Sistemas de información geográfica y sensores remotos. Aplicaciones en enfermedades transmitidas por vectores
PARRA-HENAO,GABRIEL;
CES Medicina , 2010,
Abstract: geographic information systems (gis) and remote sensing (rs) are powerful tools for the study of actual distribution and to predict risk areas for insect vectors of diseases. both have been using increasingly to target prevention and control actions. the use of these techniques in research about vector-borne tropical diseases is growing in the last years; however its application in official control programs has been limited. this paper briefly reviews the use of spatial analysis, geographic information systems and remote sensing in different vector species and deal with the future challenges for the potential application of these techniques in official control programs in colombia. finally, to advance in vectorborne control programs, training of researchers and decision makers in these tools are recommended. the increase of collaboration between institutions and the collection of information about the distribution of vector species in a standardized way and the development of a common data platform is recommended too.
