Thiel embalming in neonates: methodology and benefits in medical training.

Current teaching and training methods for surgical techniques in the pediatric population involve artificial models (manikins), animals or adult human cadavers embalmed using various techniques. We found no references in the literature concerning the use of the Thiel method in the pediatric population. The aim of this study, therefore, was to assess the viability of using pediatric human cadavers embalmed through Thiel's technique and to compare them with standard pediatric manikins. After donation of a 24-week stillborn, the Thiel technique was carried out for fixation following the usual protocol. A video recording with eye-tracking glasses was used to perform an examination, and techniques. The same procedures were conducted on a pediatric manikin. Medical students, medical residents and physicians were asked to respond to questions in an online survey after being shown the video. A total of 92 responses were obtained. The Thiel-embalmed stillborn was assessed as superior to the manikin in all items. Our study confirmed that this technique is feasible even with extremely small donors. The value of this form of preservation for medical training is not widely known though it is receiving increasing interest. Our results show that Thiel fixation in pediatrics is clearly more highly valued than a manikin and offers great potential. This innovative application of the Thiel method in the pediatric population is technically possible. It poses no additional difficulties and is very positively assessed for undergraduate and postgraduate teaching.

The Application of a System of Eye Tracking in Laparoscopic Surgery: A New Didactic Tool to Visual Instructions.

Introduction: Laparoscopic surgery is an increasingly used technique, but it requires a high degree of learning, and communication between the operating room crew is considerably difficult. The use of eye tracking has been proposed as a didactic and evaluation tool in several settings, including in laparoscopy in simulators. Objectives: This study aimed to evaluate the usefulness of the use of eye tracking systems (Tobii glasses 2) in laparoscopic surgery as a didactic and assessment tool to improve communication in the operating room and improve patients' security. Methodology: An anonymous survey was sent to the students and medical teachers of a faculty of medicine and practicing doctors and residents. The message contained an explanation about the use of the Tobii glasses, a link to watch the video showing its use in a laparoscopic surgery, and the survey to complete after watching the video. Results: The survey was answered by 113 participants (51.3% medical students, 27.4% medical teachers, 18.6% practicing doctors, and 2.7% medicine residents). Eighty-three percent agreed with the usefulness of the "Tobii glasses" in the operating room for improving communication between the main surgeon and the assistant, for learning complex surgery techniques, for obtaining didactic videos, and for indicating anatomical structures. The item scored worst was the price of the glasses. Conclusions: It is possible to record and project expert gaze patterns in the operating room in real time using the Tobii glasses. This device allows improving communication among the surgical crew and the learning of residents and also improving the security of surgical patients.

Situación actual de la organización, recursos y actividad en cardiología pediátrica en España / Current situation of the organisation, resources and activity in paediatric cardiology in Spain

Introducción: Presentamos el trabajo "situación actual de la organización, recursos y actividad en cardiología pediátrica en España", promovido por la Sociedad Española de Cardiología Pediátrica y Cardiopatía Congénitas. Material y métodos: El estudio se elaboró con los resultados obtenidos de un cuestionario elaborado por la Sociedad Española de Cardiología Pediátrica y Cardiopatía Congénitas, remitido a todos los hospitales del territorio nacional con actividad en cardiología pediátrica. Resultados: Ochenta y seis respondieron el cuestionario, 14 de los cuales disponen de cirugía cardíaca infantil. Los recursos humanos incluyen 190 médicos, 40 cirujanos y 27 MIR. Todos los hospitales disponen de material para el diagnóstico inicial adecuado, y solo los hospitales terciarios disponen de técnicas de diagnóstico específico, cardiología intervencionista y cirugía cardíaca. La atención a los pacientes, en consulta externas y en la hospitalización es realizada o supervisada mayoritariamente por cardiólogos pediátricos. Existe diversidad en los profesionales que realizan las ecocardiografías fetales, ya que en un porcentaje considerable de hospitales sigue siendo realizada en exclusiva por los obstetras. El número de procedimientos diagnósticos y terapéuticos fueron similares al registro previo, con un leve descenso de cirugía cardíaca cerrada y un aumento proporcional de cateterismos terapéuticos. Conclusiones: La cardiología pediátrica en España es realizada por pediatras con formación en cardiología pediátrica mayoritariamente. La mayoría de los centros disponen de medios adecuados de diagnóstico, y solo los hospitales terciarios cuentan con técnicas de diagnóstico específico, cardiología intervencionista y cirugía cardíaca. En futuros estudios, debemos no únicamente cuantificar las técnicas de diagnóstico y tratamiento sino también, aspirar a la cuantificación de resultados clínicos

Introduction: The results are presented on the "current situation of the organisation, resources and activity in paediatric cardiology in Spain". It was promoted by the Spanish Society of Paediatric Cardiology and Congenital Heart disease. Material and methods: An analysis was carried out on the results obtained from a specifically designed questionnaire, prepared by the Spanish Society of Paediatric Cardiology and Congenital Heart disease, that was sent to all hospitals around the country that offer the speciality of paediatric cardiology. Results: A total of 86 questionnaires were obtained, including 14 hospitals that perform cardiac surgery on children. A total of 190 paediatric cardiology consultants, 40 cardiac surgeons, and 27 middle grade doctors performing their paediatric residency (MIR program) were identified. All hospitals had adequate equipment to perform an optimal initial evaluation of any child with a possible cardiac abnormality, but only tertiary centres could perform complex diagnostic procedures, interventional cardiology, and cardiac surgery. In almost all units around the country, paediatric cardiology consultants were responsible for outpatient clinics and hospital admissions, whereas foetal cardiology units were still mainly managed by obstetricians. The number of diagnostic and therapeutic procedures was similar to those reported in the first survey, except for a slight decrease in the total number of closed cardiac surgery procedures, and a proportional increase in the number of therapeutic catheterisations. Conclusions: Paediatric Cardiology in Spain is performed by paediatric cardiology consultants that were trained initially as general paediatricians, and then completed a paediatric cardiology training period. Almost all units have adequate means for diagnosis and treatment. Efforts should be directed to create a national registry that would not only allow a prospective quantification of diagnostic and therapeutic procedures, but also focus on their clinical outcomes

Use of Eye Tracking as an Innovative Instructional Method in Surgical Human Anatomy.

OBJECTIVE: Tobii glasses can record corneal infrared light reflection to track pupil position and to map gaze focusing in the video recording. Eye tracking has been proposed for use in training and coaching as a visually guided control interface. The aim of our study was to test the potential use of these glasses in various situations: explanations of anatomical structures on tablet-type electronic devices, explanations of anatomical models and dissected cadavers, and during the prosection thereof. An additional aim of the study was to test the use of the glasses during laparoscopies performed on Thiel-embalmed cadavers (that allows pneumoinsufflation and exact reproduction of the laparoscopic surgical technique). The device was also tried out in actual surgery (both laparoscopy and open surgery). DESIGN: We performed a pilot study using the Tobii glasses. SETTING: Dissection room at our School of Medicine and in the operating room at our Hospital. PARTICIPANTS: To evaluate usefulness, a survey was designed for use among students, instructors, and practicing physicians. RESULTS: The results were satisfactory, with the usefulness of this tool supported by more than 80% positive responses to most questions. There was no inconvenience for surgeons and that patient safety was ensured in the real laparoscopy. CONCLUSION: To our knowledge, this is the first publication to demonstrate the usefulness of eye tracking in practical instruction of human anatomy, as well as in teaching clinical anatomy and surgical techniques in the dissection and operating rooms.

Estudio básico e implicaciones clínicas del falso tendón del ventrículo izquierdo. ¿Está asociado al soplo inocente infantil o a enfermedad cardiaca? / Basic study and clinical implications of left ventricular false tendon. Is it associated with innocent murmur in children or heart disease?

Introducción y objetivos. El falso tendón del ventrículo izquierdo es una estructura descrita anatómicamente por Turner. Se desconoce su función dentro de la fisiología cardiaca. Se ha postulado, sin alcanzar consenso, su relación con diversas alteraciones eléctricas o funcionales. El objetivo es conocer cuándo aparece, su prevalencia, su composición histológica y su asociación con el soplo inocente infantil o con enfermedad cardiaca. Métodos. La investigación básica se realizó por la disección anatómica en cadáveres de corazones humanos adultos para describir el falso tendón y su histología. La investigación clínica se realizó en población pediátrica mediante ecocardiografía y se analizó su relación con cardiopatía, el soplo inocente infantil u otras alteraciones. Prenatalmente se realizaron ecocardiografías fetales a diferentes edades gestacionales. Resultados. La presencia del falso tendón es la norma en la disección cardiaca, y está constituido por fibras de tejido muscular y conectivo. En la población pediátrica, la presencia ecocardiográfica del falso tendón fue del 83%, y solo mostró relación estadísticamente significativa con el soplo inocente infantil y una menor aceleración de la aorta. Por ecocardiografía fetal, se objetivó su presencia desde al menos la semana 20 de gestación. Conclusiones. El falso tendón del ventrículo izquierdo es una normalidad clínica visible por ecocardiografia fetal ya desde la semana 20, con presencia hasta la edad adulta sin relación con enfermedad, únicamente con la presencia de soplo inocente en edad pediátrica; queda por determinar si es la causa del soplo y si es su ausencia o anomalías estructurales lo que se relaciona con enfermedad (AU)

Introduction and objectives. Left ventricular false tendon is a structure of unknown function in cardiac physiology that was first described anatomically by Turner. This condition may be related to various electrical or functional abnormalities, but no consensus has ever been reached. The purpose of this study was to determine the time of appearance, prevalence and histologic composition of false tendon, as well as its association with innocent murmur in children and with heart disease. Methods. The basic research was performed by anatomic dissection of hearts from adult human cadavers to describe false tendon and its histology. The clinical research consisted of echocardiographic study in a pediatric population to identify any relationship with heart disease, innocent murmur in children, or other abnormalities. Fetal echocardiography was performed prenatally at different gestational ages. Results. False tendon was a normal finding in cardiac dissection and was composed of muscle and connective tissue fibers. In the pediatric population, false tendon was present in 83% on echocardiography and showed a statistically significant association only with innocent murmur in children and slower aortic acceleration. The presence of false tendon was first observed on fetal echocardiography from week 20 of pregnancy. Conclusions. Left ventricular false tendon is a normal finding visualized by fetal echocardiography from week 20 and is present until adulthood with no pathologic effects except for innocent murmur during childhood. It remains to be determined if false tendon is the cause of the murmurs or if its absence or structural anomalies are related to disease (AU)
