Is Cadaveric Dissection The "Gold Standard" For Neuroanatomy Education?

Graphic medicine meets human anatomy: The potential role of comics in raising whole body donation awareness in Italy and beyond. A pilot study

Cadaver dissection has always played a fundamental role in medical education. However, especially in Italy, the topic of body donation has remained partially unknown for years. The current study analyses graphic medicine as a new possible communication tool, evaluating and reflecting, with second-year students enrolled in the International School of Medicine and Surgery at the University of Bologna, about its potentialities for body donation awareness-raising in both the scientific community and the general population. For the first time in an Italian University, two graphic medicine workshops were organized focusing on human anatomy and body donation. Seminars were positively evaluated by students using a four items Likert-scale question: mean 3.54 (± SD 0.73) for the Likert question about the experiences of the workshops; 3.88 (± 0.33) for the Likert question regarding the use of graphic medicine in body donation awareness campaigns among the general population; 3.59 (± 0.65) for the Likert question regarding the use of graphic medicine in body donation awareness campaigns among the scientific community. Furthermore, the open-ended questions included in the anonymous questionnaire were analyzed using the constructivist grounded qualitative analysis, whence various themes emerged. Finally, five graphic medicine projects about body donation were created by students, proving their interest in testing this method to promote body donation, focusing the attention on different communicative aspects. Considering the results of this pilot study, the co-creative collaborative use of graphic medicine could be evaluated as an additional strategy to increase body donation awareness-raising in Italy and beyond, especially in the non-experts' community.

Practical anatomy classes: An alternative to improve the learning of middle school students

Anatomy is the branch discipline focused on studying organisms' physical structures and parts. Although technological advances are broadening the anatomy study, the practices of prosection and dissection of human cadavers and animals remain a primary teaching method. Despite the large body of research supporting its benefits, in some countries, cadaveric prosection and dissection of vertebrate animals in secondary education have been banned. In the current study, to prevent a lack of access to anatomical sciences education, the use of plastinated biological specimens was proposed for teaching practical biology in middle and high schools. The study was conducted in the 2014 academic year. Eighty-seven middle school students participated in the experiment. Groups consisted of: (i) theoretical classes only; (ii) theoretical class plus prosection with fresh specimens class; (iii) theoretical class plus expository with plastinated specimens classes. A post-test grade method was used to assess the impact of such tasks on the learning experience of each group. An ANOVA test and multiple regression model were used to analyze the effects of the variables of interest. Our study highlighted that students who underwent the plastination practical class had higher overall performance and a higher mean post-test grade than those in the pure theoretical group. A favorable effect of a positive self-knowledge assessment on the students' performance was found, supporting the self-efficacy model of human behavior. Thus, the current study provides further evidence to support the use of plastinated specimens as an effective teaching method in countries where dissection is not feasible.

Effectiveness of 3D-printed models prepared from radiological data for anatomy education: A meta-analysis and trial sequential analysis of 22 randomized, controlled, crossover trials

BACKGROUND

Many academicians suggested the supplementary use of 3D-printed models reconstructed from radiological images for optimal anatomy education. 3D-printed model is newer technology available to us. The purpose of this systematic review was to capture the usefulness or effectiveness of this newer technology in anatomy education.

MATERIALS AND METHODS

Twenty-two studies met the inclusion and exclusion criteria for quantitative synthesis. The included studies were sub-grouped according to the interventions and participants. No restrictions were applied based on geographical location, language and publication years. Randomized, controlled trial, cross-sectional and cross-over designs were included. The effect size of each intervention in both participants was computed as a standardized mean difference (SMD).

RESULTS

Twenty-two randomized, controlled trials were included for quantitative estimation of effect size of knowledge acquisition as standardized mean difference in 1435 participants. The pooled effect size for 3D-printed model was 0.77 (0.45-1.09, 95% CI, P < 0.0001) with 86% heterogeneity. The accuracy score was measured in only three studies and estimated effect size was 2.81 (1.08-4.54, 95% CI, P = 0.001) with 92% heterogeneity. The satisfaction score was examined by questionnaire in 6 studies. The estimated effect size was 2.00 (0.69-3.32, 95% CI, P = 0.003) with significant heterogeneity.

CONCLUSION

The participants exposed to the 3D-printed model performed better than participants who used traditional methodologies. Thus, the 3D-printed model is a potential tool for anatomy education.

AEducaAR, Anatomical Education in Augmented Reality: A Pilot Experience of an Innovative Educational Tool Combining AR Technology and 3D Printing

Gross anatomy knowledge is an essential element for medical students in their education, and nowadays, cadaver-based instruction represents the main instructional tool able to provide three-dimensional (3D) and topographical comprehensions. The aim of the study was to develop and test a prototype of an innovative tool for medical education in human anatomy based on the combination of augmented reality (AR) technology and a tangible 3D printed model that can be explored and manipulated by trainees, thus favoring a three-dimensional and topographical learning approach. After development of the tool, called AEducaAR (Anatomical Education with Augmented Reality), it was tested and evaluated by 62 second-year degree medical students attending the human anatomy course at the International School of Medicine and Surgery of the University of Bologna. Students were divided into two groups: AEducaAR-based learning ("AEducaAR group") was compared to standard learning using human anatomy atlas ("Control group"). Both groups performed an objective test and an anonymous questionnaire. In the objective test, the results showed no significant difference between the two learning methods; instead, in the questionnaire, students showed enthusiasm and interest for the new tool and highlighted its training potentiality in open-ended comments. Therefore, the presented AEducaAR tool, once implemented, may contribute to enhancing students' motivation for learning, increasing long-term memory retention and 3D comprehension of anatomical structures. Moreover, this new tool might help medical students to approach to innovative medical devices and technologies useful in their future careers.

A Novel Cadaveric Embalming Technique for Enhancing Visualisation of Human Anatomy

Within the discipline of anatomical education, the use of donated human cadavers in laboratory-based learning activities is often described as the 'gold standard' resource for supporting student understanding of anatomy. Due to both historical and educational factors, cadaveric dissection has traditionally been the approach against which other anatomy learning modalities and resources have been judged. To prepare human donors for teaching purposes, bodies must be embalmed with fixative agents to preserve the tissues. Embalmed cadavers can then be dissected by students or can be prosected or plastinated to produce teaching resources. Here, we describe the history of cadaveric preservation in anatomy education and review the practical strengths and limitations of current approaches for the embalming of human bodies. Furthermore, we investigate the pedagogic benefits of a range of established modern embalming techniques. We describe relevant cadaveric attributes and their impacts on learning, including the importance of colour, texture, smell, and joint mobility. We also explore the emotional and humanistic elements of the use of human donors in anatomy education, and the relative impact of these factors when alternative types of embalming process are performed. Based on these underpinnings, we provide a technical description of our modern Newcastle-WhitWell embalming process. In doing so, we aim to inform anatomy educators and technical staff seeking to embalm human donors rapidly and safely and at reduced costs, while enhancing visual and haptic tissue characteristics. We propose that our technique has logistical and pedagogic implications, both for the development of embalming techniques and for student visualisation and learning.
