    Arteria Lusoria and its relation to Dysphagia Lusoria. A systematic review
    (2022) Syed, Qareen H.; Valenzuela, Juan J.; Orellana, Mathias; Farfán C., Emilio; Gold, Marjorie; Beas, Antonia
    Anatomically, the aberrant subclavian artery is the last branch of the aortic arch. On its way to the right upper limb it runs posterior to the esophagus. During this passage it can compress the esophagus, producing Lusoria Dysphagia.

    Morphological study on the origin of the semitendinosus muscle in the long head of biceps femoris
    (2021) Farfán C., Emilio; Rojas, Santiago; Olivé Vilas, Ramon; Rodríguez Baeza, Alfonso
    Hamstring muscle injuries are the most prevalent among athletes who engage in sprinting activities. Their most frequent location is where the long head of the biceps femoris joins with the semitendinosus muscle to form the conjoint hamstring tendon. Just distal to this area, an additional group of fibers of the semitendinosus originate from medial aspect of biceps femoris. The objective of this study was to analyze the morphological characteristics of this union and to discuss its potential role in hamstring tears. Anatomical dissection was performed on 35 thighs. Samples obtained from this region were sectioned and stained with Masson's trichrome for further histological evaluation. A group of fibers from the semitendinosus muscle originating from the long head of the biceps femoris were observed in all 35 specimens. This origin was located 67 +/- 12 mm from the ischial tuberosity and was 32 +/- 14 mm in length. This group of muscle fibers had a width of 10.9 +/- 5.3 mm and a thickness in the anteroposterior axis of 3.2 +/- 1.4 mm. Its pennation angle was 9.2 +/- 1.5 degrees. Microscopic examination showed muscle cells from both muscles contacting interposed tendinous tissue. In conclusion, fibers of the semitendinosus muscle consistently arise from the proximal aspect of the long head of biceps femoris. The morphological characteristics of this junction have functional implications. The horizontal component of the semitendinosus vector could pull the long head of the biceps femoris medially during its shortening-lengthening cycle, rendering it an intrinsic risk factor for hamstring injuries.

    Plataforma Móvil Basada en la Nube para Mejorar la Experiencia de Aprendizaje en la Anatomía Humana
    (2021) Rojos, Felipe; Stambuk, Mónica; Neyem, Andrés; Farfán C., Emilio; Inzunza, Oscar
    En la actualidad, los cursos en línea han masificado y modificado la forma en que se enseña. Tanto los MOOC como los SPOC presentan soluciones sólidas para enseñar, e incluso poseen herramientas para fomentar la colaboración. A pesar de esto, las herramientas que poseen no fomentan colaboración efectiva y tampoco tienen una forma de medirla. Por otro lado, en anatomía han surgido múltiples aplicaciones debido a las dificultades de acceso a material cadavérico, sin embargo, éstas carecen de colaboración y no entregan información enriquecida del comportamiento y aprendizaje de los estudiantes. Dado esto, presentamos una plataforma móvil basada en la nube, como estrategia de herramienta educacional, que busca fomentar la colaboración en la enseñanza para estudiantes de anatomía y entregar datos que permiten analizar y mejorar la experiencia de aprendizaje. Esta solución se desarrolló usando como eje central las metodologías ágiles de desarrollo. Para el experimento, 29 voluntarios formaron parte del grupo experimental y otros 99 del grupo de control. Se realizaron 2 pruebas para medir sus conocimientos en áreas específicas de la anatomía. Se obtuvo aumentos de 0,59 % y 2,98 % en el puntaje de las pruebas, además, hubo una disminución en la desviación estándar de 11,434 a 5,216 en la primera prueba, y de 6,623 a 3,514 en la segunda prueba, mostrando mejora en ambos casos para el grupo experimental. Los resultados obtenidos muestran un potencial de mejorar la experiencia de aprendizaje al usar este tipo de herramientas educativas.

    Profile of morphology teachers in chilean universities
    (2021) Farfán C., Emilio; Cárdenas, Julio; Espinoza Navarro, Omar; Lizana, Pablo A.; Pacheco, Juan; Salinas, Paulo; Riveros, Andrés; Villarroel, Mauricio
    University teaching in Chile has been influenced in recent decades by changes to the education system, which has increased universities and academic offerings and, therefore, the demand for new instructors. Teaching morphological sciences has not been exempt from these changes, with new instructors needed to fill the growing offerings of programs that include anatomy, embryology and histology. The aim was to understand the profile of the academics teaching morphology in Chile in 2020. A voluntary online survey was applied to 213 university morphology teachers, in which information was collected on professional and academic training, geographical distribution, gender, continuing academic education and employment situation. Overall, the results show that 65.9 % of instructors were men and 35.1 % women, and most (34.6 %) had between 5 and 10 years in morphology, and a master's degree was predominant (53.27 %). In the area of anatomy, 46 % of instructors were physiotherapists and 24.6 % dentists, whereas in the areas of histology and embryology, the group was diverse. In terms of employment, 49.06 % stated they worked full time, mainly in teaching .41.31 % of the instructors were concentrated in the Metropolitan Region. There was no association between gender and graduate training, maximum academic degree attained, type of workday or academic profile, but there was one by disciplinary area. The conclusion drawn is that morphology teachers in Chilean universities are part of a wide range of professionals dedicated to different disciplinary areas, with master's degree and/or specialization, located mainly in the Metropolitan Region. This multidisciplinary profile demonstrates the mainstreaming of morphology teaching in Chile.
