Encefalitis amebiana granulomatosa por Balamuthia mandrillaris en Chile confirmada con secuenciación de ADN / Granulomatous amoebic encephalitis due to Balamuthia mandrillaris in Chile confirmed with DNA sequencing

Las enfermedades causadas por amebas de vida libre son infecciones oportunistas que pueden tener un curso fatal. Pueden producir afecciones diseminadas graves con compromiso del sistema nervioso central, como la encefalitis amebiana granulomatosa. Esta infección es cada vez más frecuente en América Latina, aunque se reconocen tardíamente debido a la similitud con otras patologías o porque es inusual incluirla en el diagnóstico diferencial. Comunicamos un caso fatal de una encefalitis amebiana granulomatosa por Balamuthia mandrillaris en una niña de 10 años. Destacamos la gravedad de la afectación cerebral y la falta de esquemas antimicrobianos validados para su tratamiento. Hoy en el mundo esta infección es considerada una enfermedad emergente, influenciada por el cambio climático, lo que llama a estar atentos a su presencia.

Diseases caused by free-living amoebae are opportunistic infections that can have a fatal course. They can cause very serious disseminated conditions with involvement of the central nervous system such as granulomatous amoebic encephalitis. This infection has become more common in Latin America, although its recognition is late due to the similarity with other pathological conditions or because it is unusual to include it in the differential diagnosis. We report a fatal case of granulomatous amoebic encephalitis due to Balamuthia mandrillaris in a 10-year-old girl. We highlight the severity of the brain involvement and the lack of validated schemes for its treatment. Today in the world this infection is considered an emerging disease, influenced by climate change, which calls for being attentive to its presence.

Transradial access for pediatric teenage neurointervention: A single-center case series.

Transradial access is widely used in cardiological adult interventions and less in pediatrics. In recent years, this access has become more popular in the neuroradiological community in adult patients since it has fewer complications and is more comfortable for the patient after the procedure. We present a single-center case series of 52 transradial access neurointerventions (43 angiographies and 9 therapeutic procedures) in pediatric patients, with a failure of 4 cases (7.7%) in which we could not puncture the artery, crossing over to transfemoral access. Since in five cases we did angiography followed by therapeutic intervention, thus doing only one puncture access for both procedures, then our access failure rate was 10.6%. The 34 successful transradial access solely angiographies had a median radiation exposure of 887 mGy (interquartile range 628-1352), median fluoroscopy time of 9.5 min (interquartile range 7.5-15.3), and median procedure time of 28 min (interquartile range 24-33 min) Therapeutic procedure diagnosis were: one ruptured saccular aneurysm, two juvenile nasopharyngeal angiofibromas, and five arteriovenous malformations. The transradial access neurointerventions for pediatric population older than 11 years is safe and feasible, having previous experience in adults. Younger population should be considered on a case-to-case basis, depending on ultrasound measurement of the arterial diameter and the materials available.

Ingeniería para los Hospitales Públicos: el caso de la Ingeniería Biomédica / Engineering for Public Hospitals

El texto trata de la inversión en equipamientos biomédicos en los últimos diez años, para desentrañar otra visión de la ingeniería biomédica en el hospital público. Para ello, discute la innovación y el desarrollo en hospitales públicos, la incorporación de la tecnología a nivel local y el papel de la gestión de la ingeniería.

Carlos Molina Bustos: el salubrista que se graduó de historiador a los 69 años / Carlos Molina Bustos: the health professional who graduated as a historian at the age of 69

Breve biografía del Dr. Carlos Molina, un médico que amó la historia y, claro, entre los profesionales de la salud, que se rindió con mayor profesionalismo a su pasión, con la humildad. Su legado sirve para un reencuentro entre historiadores y profesionales de salud y entre generaciones.

[Health statistics aren't born in a cabbage patch: Jesuits, political arithmetic, stigmergy and oligopticons]. / Las estadísticas de salud no nacen de un repollo: jesuitas, aritméticas políticas, estigmergias y oligópticos.

By analyzing the content and network of production of a map from 1751, created by the circular mission of the Jesuits in Chiloé (an archipelago located off the southern coast of Chile), that contains birth, death and population data, this article discusses the role that health statistics play historically, philosophically, technically and sociologically. In doing so, the article seeks to comprehend the genesis of a process of production of data and references in order to debate what health statistics are composed of, what ends they are used for, what their connection is to the formation of collectives and the differential conditions of possibility that exist for producing statistics. We attempt to develop hypotheses that demonstrate statistics as a hybrid articulation between diverse elements, epistemological, biopolitical, historical and philosophical in nature, with facets at once religious and demographic, ontological and ethnic, scientific and governmental.

A partir de un análisis del contenido y la red productora de un mapa de 1751, elaborado por la misión circular de los jesuitas en Chiloé (archipiélago ubicado en la costa austral chilena), que contiene cifras de nacimientos, defunciones y habitantes, este artículo discute el rol de las estadísticas de salud, en diferentes registros: históricos, filosóficos, técnicos y sociológicos. De este modo, se busca comprender la génesis de un proceso de producción de cifras y referencias, para debatir de qué están hechas las estadísticas de salud, qué roles cumplen, sus vínculos con la construcción de colectivos y las condiciones de posibilidad de producciones diferentes. Tratamos de ensayar algunas hipótesis que muestran las estadísticas como articulación híbrida de elementos de índole muy diversa: epistemológicos, biopolíticos, históricos y filosóficos, reconociendo en ellos facetas religiosas y demográficas, ontológicas y étnicas, científicas y de gobierno.
