- ItemAn online training and feedback module enhances the musculoskeletal examination performance of medical interns(2024) Arteaga, Matías; Vidal Olate, Catalina Victoria; Ruz, Cristián; Zilleruelo Cañas, Raúl Andrés; Pino Piemonte, Ernesto Arnaldo; Dauvergne Ogaz, Javier Alejandro; Besa Vial, Pablo José; Irarrázaval, SebastiánBackground: Pathologies of the locomotor system are frequent and can cause disability and impact the quality of life of the people affected. In recent years, online training and feedback have emerged as learning tools in many fields of medicine. Objective: This study aims to evaluate medical interns’ musculoskeletal examination performance after completing an online training and feedback module. Methods: This study employed a quasi-experimental design. Medical interns were invited to complete a 4-week musculoskeletal physical examination training and feedback module via an e-learning platform. The course included written and audiovisual content pertaining to medical history, physical examination, and specific tests for the diagnosis of the most common knee, spine, shoulder, ankle, and foot conditions. Before and after completing the module, their ability to perform the physical examination was evaluated using an objective structured clinical examination (OSCE) with simulated patients that took place face-to-face. A control group of experts was assessed using the OSCE, and their performance was compared to that of the interns before and after the training. At the end of the module feedback on the OSCE was provided to participants through the platform asynchronously and two evaluation questions about the user experience were conducted at the end of the study. Results: A total of 35 subjects were assessed using the OSCE, including 29 interns and 6 experts. At the beginning of the training module, the group of interns obtained an average score of 50.6±15.1. At the end of the module, 18 interns retook the OSCE, and their performance increased significantly to an average of 76.6±12.8 (p<0.01). Prior to the training, the experts performed significantly better than the interns (71.2 vs. 50.6; p=0.01). After the interns received the training and feedback, there were no significant differences between the two groups (71.2 vs. 76.6; p=0.43). Two evaluation questions were conducted at the end of the study, revealing that 93% of the participants affirm that the training module will be useful in their clinical practice, and 100% of the participants would recommend the training module to a colleague. Conclusión: The online training and feedback module enhances the musculoskeletal examination performance of medical interns.
- Item¿Cómo es la calidad de vida reportada por los estudiantes de Medicina?(2018) Irribarra Trivelli, Luis Alfonso; Mery I., Pamela; Lira Salas, María Jesús; Campos Daziano, Mauricio Andrés; González L., Francisca; Irarrázaval, SebastiánBackground: The high academic burden may hamper the quality of life of medical students. Aim: To evaluate the quality of life (QOL) for medical students attending a Chilean university. Material and Methods: Four hundred eleven medical students aged 22 ± 2 years (51% women), studying in Santiago, Chile, answered online a validated Spanish version of the WHOQOL-BREF quality of life survey (scored from 0 to 100). Overall scores were assessed for the questionnaire domains Physical health, Psychological health, Interpersonal relationships, and Environment. Results: The global scores were 65.1 for Physical health, 63.1 for Psychological health, 61.3 for Interpersonal relationships and 67.2 for Environment. Students in clinical practice, females, those with sedentary behaviors and consuming modafinil had lower Physical health scores. Students coming from outside Santiago, with sedentary behaviors and who consumed modafinil had poorer Psychological health scores. Students coming from outside Santiago, males and those with sedentary behaviors had Lower Interpersonal relationship scores. Environment scores were also lower among students who were sedentary or from outside Santiago. Conclusions: The variables that had a greater negative impact in the quality of life of these students were the transition from theoretical courses to clinical practice, being from outside Santiago, being overweight or obese and consuming modafinil. Students that were physically active had better quality of life scores.

- ItemDoes anatomic single-bundle ACL reconstruction using hamstring autograft produce anterolateral meniscal root tearing?(2017) Irarrázaval, Sebastián; Masferrer-Pino, Angel.; Ibañez, Maximiliano.; Shehata, Tamer M. A.; Naharro, María.; Monllau, Joan C.Abstract Background To determine if tibial tunnel reaming during anatomic single-bundle anterior cruciate ligament (ACL) reconstruction using hamstring autograft can result in anterolateral meniscal root injury, as diagnosed by magnetic resonance imaging (MRI). Methods A case series of 104 primary anatomic single-bundle ACL reconstructions using hamstring autograft was retrospectively reviewed. Pre- and post-operative (>1 year) MRIs were radiologically evaluated for each patient, with a lateral meniscus extrusion > 3 mm at the level of the medial collateral ligament midportion on a coronal MRI, to establish anterolateral meniscal root injury. Results No patients presented radiological findings of anterolateral meniscal root injury in this case series. Conclusions Examining a single-bundle ACL reconstruction technique using hamstring autograft that considered tibial tunnel positioning in the center of the tibial footprint, this case series found no evidence of anterolateral meniscal root injury in patient MRIs, even more than 1-year post-operation.Abstract Background To determine if tibial tunnel reaming during anatomic single-bundle anterior cruciate ligament (ACL) reconstruction using hamstring autograft can result in anterolateral meniscal root injury, as diagnosed by magnetic resonance imaging (MRI).

- ItemXantomatosis cerebrotendínea: Una causa de aumento de volumen bilateral del tendón de Aquiles. Caso clínico(2009) Filippi Nussbaum, Jorge Luis; Irarrázaval, Sebastián; Preredo O., Pilar; Mellado T., PatricioCerebrotendinous xanthomatosis is an inherited autosomal recessive disease caused by a mutation in the gene for the sterol 27-hydroxylase enzyme, which determines the accumulation of plasmatic cholestanol in various tissues. The natural history of this disease is characterized by chronic diarrhea beginning in childhood, cataract in youth, tendinous xanthomas in adulthood and later progressive neurological dysfunction manifested as dementia, psychiatric disorders, cerebellar, pyramidal or extrapyramidal signs or seizures. We report a 39 year-old male with a history of diarrhea during childhood and bilateral cataracts requiring surgery at 20 years of age, who evolves later with psychiatric disorders and bilateral increased volume in Achilles tendons. High levels of plasmatic cholestanol and magnetic resonance imaging confirmed the diagnosis of this disease.
