RESUMO
Histopathological assessment of tissue samples after prolonged formalin fixation has been described previously, but currently there is only limited knowledge regarding the feasibility of molecular pathology on such tissue. In this pilot study, we tested routine molecular pathology methods (DNA isolation, DNA pyrosequencing/next-generation sequencing, DNA methylation analysis, RT-PCR, clonality analysis and fluorescence in situ hybridization) on tissue samples from 11 tumor entities as well as non-neoplastic brain tissue from 43 body donors during the gross anatomy course at Ulm University (winter semester 2019/20 and 2020/21). The mean post mortem interval until fixation was 2.5 ± 1.6 days (range, 1-6 days). Fixation was performed with aqueous formaldehyde solution (formalin, 1.5-2%). The mean storage time of body donors was 12.8 ± 5.6 months (range, 7-25 months). While most diagnostic methods were successful, samples showed significant variability in DNA quality and evaluability. DNA pyrosequencing as well as next-generation sequencing was successful in all investigated samples. Methylation analyses were partially not successful in some extend due to limited intact DNA yield for these analyses. Taken together, the use of prolonged formalin-fixed tissue samples from body donors offers new avenues in research and education, as these samples could be used for morpho-molecular studies and the establishment of biobanks, especially for tissue types that cannot be preserved and studied in vivo. Pathological ward rounds, sample collection, and histopathological and molecular workup have been integrated in the gross anatomy course in Ulm as an integral part of the curriculum, linking anatomy and pathology and providing medical students early insight into the broad field of (molecular) pathology.

The femoral epicondyle is an anatomical bony landmark essential for surgeons and anatomists, but there are discrepancies between the two fields when using this term. In current orthopedic surgery, it commonly denotes the small bony prominence of the femoral condyle. Given the derivation, "epicondyle" should be a region projecting laterally from the articular surface rather than a point. These discrepancies in usage are found not only between the fields but also in the literature. This article reviews the narrative definition of "epicondyle of the femur" in surgery and the evolution of the term in anatomy. The outcomes of the review suggest a relationship between the differing perceptions of the epicondyle and the evolution of the term. In reports of studies related to the epicondyle, it is strongly recommended that the definition of the word is clearly stated, with an understanding of its evolution.

Histological observation under light microscopy has long been used in human cadaveric studies. However, it can distort the interpretations of findings if not used appropriately; there is no guide for its proper use. The aim of this article is to revisit and discuss the correct use of histology in human cadaveric studies, following discussions with experts in multiple fields of medicine, and to create the first guide for such usage. We reached a consensus with the experts, agreeing that when this principle (structure, quantification, interaction, position: SQIP) is applied to histological observations, the findings will be interpreted correctly. Appropriate use of this recommendation can make human cadaveric studies more accurate and informative. This is the first histology guide for human cadaveric studies.

Effective communication and precise navigation within the intricacies of the human body rely on robust anatomical terminology. Since its creation by the Federative Committee on Anatomical Terminology (FCAT), the Terminologia Anatomica (TA 1998) has consistently served as the benchmark in the field. However, the constant advancement of anatomical knowledge requires regular revisions, updates, and enhancements of anatomical nomenclature to accommodate the latest scientific discoveries. The recent adoption of the second edition of Terminologia Anatomica (TA 2019) by the International Federation of Associations of Anatomists (IFAA) has drawn attention to certain notable omissions. Despite over a century of dedicated work establishing standard anatomical terminology, specific widely recognized gross anatomical structures are still absent from the official listing in the Terminologia Anatomica. There is, however, a consensus that the inclusion of names for trivial or variably present structures should be avoided. Accordingly, this article focuses on a thoughtfully selected group of anatomical structures, which are so important that they are routinely discussed during anatomy courses, despite their exclusion from the official lists of anatomical terms. These basic structures hold fundamental importance for both anatomy education and clinical practice. Consequently, their appropriate nomenclature warrants consideration for inclusion in future editions of TA.
RESUMO
Learning human anatomy is essential for Doctor of Physical Therapy (DPT) education. Body donors are traditionally utilized to understand content, but in a hybrid learning environment, students have limited time to use body donors. To improve body donor access and learning, we created online synchronous pre-body donor activities. The impact of these online strategies on students' subsequent exams and final grade were investigated in a non-randomized, observational study. These activities were hypothesized to positively influence students' anatomy performance. In a 16-week semester, DPT students (case [n = 91], control [n = 22]) participated in a hybrid program of asynchronous/synchronous online learning and two in-person immersions. Measures included student course grades and teaching surveys. Spearman's rho correlations analyzed the relationship between four pre-body donor quizzes to body donor exams, written exams, and final course grade. Mann-Whitney U tests assessed differences in grades between cohorts. A linear regression model examined the influence of pre-body donor quizzing on exams/final grades. Correlation tests revealed a strong relationship between the average pre-body donor quiz score and both the first written exam and final course grade (p = 0.0001). The case group achieved significantly higher scores than the control group on the first in-person body donor exam (p = 0.011), the second written exam (p = 0.0001), and the final grade (p = 0.004). The pre-body donor quizzes predicted performance on the subsequent in-person body donor exams, written exams, and the final grade. Implementation of online pre-body donor learning activities was associated with increased academic performance among hybrid DPT students and may aid in learning anatomy concepts for clinical practice.

The last two decades have seen a shift in the way anatomy education is delivered. With the introduction of blended learning, cadaveric dissection is no longer the be all and end all and, in many cases, the continuing role of anatomical teaching artefacts has declined after decades of prominence. While some institutions have abandoned their archaic anatomical collections and medical museums completely, others have invested in their technological enhancement. We describe the integration of historical teaching artefacts into contemporary anatomy education through the development of an interactive online e-platform and shed light on the enduring pedagogic value of past anatomical teaching specimen.

Modern anatomy education has benefitted from the development of a wide range of digital 3D resources in the past decades, but the impact of the COVID-19 pandemic has sparked an additional demand for high-quality online learning resources. Photogrammetry provides a low-cost technique for departments to create their own photo-realistic 3D models of cadaveric specimens. However, to ensure accessibility, the design of the resulting learning resources should be carefully considered. We aimed to address this by creating a video based on a photogrammetry model of a cadaveric human lung. Students evaluated three different versions of this video in a Likert-type online survey. Most responding students found this type of video useful for their learning and helpful for the identification of anatomical structures in real cadaveric specimens. Respondents also showed a preference for specific design features such as a short video length, white text on black background, and the presence of captions. The positive student feedback is promising for the future development of photogrammetry-based videos for anatomy education and this study has provided pilot data to improve the accessibility of such videos.
RESUMO
BACKGROUND: Anatomy is a crucial part of medical education, and there have been attempts to improve this field by utilizing various methods. With the advancement of technology, three-dimensional (3D) materials have gained popularity and become a matter of debate about their effectiveness compared to two-dimensional (2D) sources. This research aims to analyze the effectiveness of 3D PDFs compared to 2D atlases. METHODS: This study is a randomized controlled trial involving 87 Year-1 and Year-2 medical students at Gazi University Faculty of Medicine, Turkey. The study was conducted in two steps. In Step-1, students were randomized to watch lecture videos on liver anatomy and male genitalia anatomy supplemented with either a 3D PDF (intervention group) or 2D atlas (control group) images. Following the video lectures, a test (immediate test) was administered. In Step-2, the same test (delayed test) was administered 10 days after the immediate test. The test scores were compared between the intervention and control groups. In addition to the descriptive analyses, Chi-square and Mann-Whitney U tests were performed. RESULTS: In the immediate test, while there was no significant difference between the groups for the liver test (p > 0.05), 3D PDF group's scores (Median = 24.50) was significantly higher than the 2D atlas group's in the genitalia test (Median = 21.00), (p = 0.017). The effect size (Cohen's d) was 0.57. In the delayed test, there was no significant difference between the groups in the liver and genitalia tests (p > 0.05). However, the effect size in the immediate genitalia test was 0.40. Year-1 students' immediate test of genitalia performances were significantly higher in the 3D PDF group (Median = 24.00) than the 2D atlas group (Median = 19.00), (p = 0.016). The effect size was 0.76. Also, Year-1 students' 3D PDF group (Median = 20.50) presented with significantly higher performance than the 2D atlas group (Median = 12.00), (p = 0.044) in the delayed test of genitalia, with the 0.63 effect size. CONCLUSION: 3D PDF is more effective than 2D atlases in teaching anatomy, especially to initial learners. It is particularly useful for teaching complex anatomical structures, such as male genitalia, compared to the liver. Hence, it may be a valuable tool for medical teachers to utilize during lectures.

The provision of distance education has increased rapidly over the past few years owing to the COVID-19 pandemic. The core of gross anatomy distance education is three-dimensional (3D) visualization of anatomical structures, and the use of simple 3D visualization tools has increased as distance education has become more popular. The purpose of this study was to establish a more effective operation plan in dental hygiene by investigating learners' opinions about distance education of gross anatomy and 3D visualization tools, and by comparing and analyzing their academic achievements. The study involved 250 students and comprised an analysis of 120 students who took a head and neck anatomy class at the Department of Dental Hygiene at D University via distance learning during 2020-2022, and 130 graduates who had completed the class via face-to-face learning during 2015-2017. An online survey of 120 of the enrolled students comprised 10 questions asking for opinions on the head and neck anatomy distance learning classes, five questions on the 3D visualization tool, and five on general characteristics. Overall, the learners had positive perceptions of distance education for head and neck anatomy and the 3D visualization tool. Among the education methods compared, they generally preferred blended learning (n = 47, 39.2%). There was a significant preference for the distance learning method of asynchronous classes (n = 86, 94.5%). Analysis of academic achievements according to whether or not distance education was conducted revealed a significantly higher score in the face-to-face class group (P < 0.05). A blended learning method can be effective in increasing learner satisfaction and improving academic achievement in gross anatomy classes on dental hygiene. It is suggested that theoretical material should be learned through asynchronous content and knowledge expanded through small-group activities during face-to-face learning. This will help establish a standard model for teaching of gross anatomy in dental hygiene in the postpandemic era.

In recent years, the logistical challenges posed by the Covid-19 pandemic have prompted medical educators teaching gross anatomy to explore an expanded use of online instructional modalities. There is concern that this shift to online anatomy education in medical schools could affect long-term learning outcomes for future healthcare providers. In this systematic review, the educational effectiveness of online anatomy teaching is compared with traditional ("face-to-face") teaching methods, specifically in terms of students' academic performance and satisfaction. A search of four databases identified and screened 162 studies. Subsequently, 31 studies were analyzed, including both (a) teaching outcome measures (test scores) and (b) student satisfaction ratings. Authors chose studies, extracted data, assessed quality and examined risk of bias. Nineteen studies compared students' academic performances between online and face-to-face teaching methods. Twenty-six studies measured students' levels of satisfaction in both teaching methods. Both qualitative and quantitative analyses of the data revealed comparable academic performances with no statistical difference between the two teaching methods, but a higher level of satisfaction with face-to-face teaching. The findings confirm that students can learn from online teaching but are more satisfied with face-to-face teaching. The authors conclude that online teaching cannot replace traditional teaching and there is no preference for one type of modality over the other. Therefore, a multi-modal learning approach combining online with face-to-face educational modalities for medical students could be efficient and successful.

PURPOSE: This article presents the evolution of the subject of vascular anatomy and discusses the associated clinical applicability. METHODS: Clinically-driven surgical examples met in our everyday practice were used to depict characteristic anatomical paradoxes raised by the inconsistencies between classical anatomical perception, current imaging modalities and modern surgical techniques. RESULTS: Consequent anatomy-driven modifications of medical devices comprise a characteristic example of the vivid, modern and meaningful role that anatomy can have on clinical decision-making and improvement of technical and clinical success. Clinical experience provides a feedback that shifts the focus of anatomic research towards new fields of interest, such as the role of arterial collateral networks as therapeutic targets. The clinical feedback brings into light queries and issues where traditional anatomical answers may be vague and inadequate to apply, thereby necessitating further research, refinement and reevaluation. CONCLUSION: While the traditional teaching of vascular anatomy is based on information and illustrations derived from dissection and prosection courses, the development of modern imaging technologies applied in large numbers of living patients and application of minimally invasive techniques challenge our understanding of what should be perceived as fixed and permanent. Moreover, the recently introduced evidence-based philosophy in anatomy elaborate more robust data which not only update, validate and enrich the existing knowledge of anatomical variations but also enable subgroup analyses with respect to race, age and sex, identifying specific anatomic features associated with a significant impact on patient treatment.

PURPOSE: Anatomical knowledge of medical students and residents is insufficient and further anatomical sciences throughout medical curriculum may be necessary. The first aim of this study was to assess pelvic and perineal anatomical knowledge retention of Obstetrics and Gynaecology (Ob/Gyn) residents. The second was to assess the impact of an e-learning tool on anatomical knowledge. METHODS: A survey was sent by mail to medical students and Ob/Gyn residents. After completion, Ob/Gyn residents were randomised to "e-learning" group or to "Control" group. "E-learning" group had an unlimited access to a tool about female pelvic and perineum anatomy, implemented by iMAIOS society in their online platform. A second assessment of residents' anatomical knowledge was done 2 months after randomisation. RESULTS: Ob/Gyn residents (N = 23) had a significant lower global score than third-year medical students (N = 103) (22.1% (± 10.2) vs 43.8% (± 12.1), p < 0.0001). Two months after randomisation, residents of "control" group demonstrated no significant difference between the two questionnaires (3.6%, p = 0.31), whilst the "e-learning" group demonstrated a significant increase overall (10.6%, p = 0.09). There was no significant difference on the post-intervention questionnaire between control and "e-learning" group (25.4% vs 33% respectively, p = 0.34). CONCLUSION: Knowledge of pelvic and perineal anatomy is poor. This e-learning tool aimed at improving anatomical knowledge retention but is not sufficient. A combination of traditional approaches and innovative solutions should be proposed throughout medical school and residency to maintain anatomical knowledge.

INTRODUCTION: Modified teaching strategies (MTS), asynchronous online teaching and smaller dissection groups, were applied to a gross anatomy course for dental students in the National Taiwan University in April 2020 in response to the COVID-19 pandemic. This study aimed to investigate the effects and perceptions of MTS on dental students. MATERIALS AND METHODS: Scores for anatomy examinations for 2018-2019 (without MTS) and 2019-2020 (with MTS) cohorts were compared to explore the effect on academic performance. Moreover, questionnaire from the 2019-2020 cohort was analysed to determine dental students' perceptions about MTS. RESULTS: The lecture performance in the final examination of the second semester for the 2019-2020 cohort was significantly higher than that of the first semester (pre-COVID-19) and that for the 2018-2019 cohort. However, the laboratory performance in the midterm examination of the second semester for the 2019-2020 cohort was significantly lower than that for the 2018-2019 cohort and showed no difference in the final examination of the first semester. The questionnaires revealed that the majority of students displayed positive attitudes towards MTS and agreed with the importance of peer discussion during laboratory dissection. CONCLUSIONS: Asynchronous online learning for anatomy lecture may be beneficial for dental students; however, a smaller dissection group accompanied by reduced peer discussion may temporarily exert negative effects on their laboratory performance at the beginning of the application. Furthermore, more dental students exhibited positive perceptions towards smaller dissection groups. These findings could illuminate the learning condition of dental students in anatomy education.

The article covers aspects of morphological, anatomical, embryological, histological aspects and origin, types, blood supply, innervation, lymph drainage of human vermiform appendix. The purpose of the study is to understand real function and to summarize this information for positive impact on clinical decision in case of appendicitis. Although characteristic features of normal and diseased appendix have been reported for many previous centuries, it still the most common challenge facing every day in operation room. The appendectomy, commonest surgical emergency procedure, may cause little confusion in surgeons due to highly variable situations of it inside the abdominal cavity. However, the recent imaging techniques have increased ability of surgeon for crucial diagnosis of the diseased appendix.

PURPOSE: Growth hormone (GH) has an important role in intestinal barrier function, and abnormalities in GH action have been associated with intestinal complications. Yet, the impact of altered GH on intestinal gross anatomy and morphology remains unclear. METHODS: This study investigated the influence of GH signaling on gross anatomy, morphology, and fibrosis by characterizing the small and large intestines in male and female bovine growth hormone transgenic (bGH) mice and GH receptor gene-disrupted (GHR-/-) mice at multiple timepoints. RESULTS: The length, weight, and circumference of the small and large intestines were increased in bGH mice and decreased in GHR-/- mice across all ages. Colon circumference was significantly increased in bGH mice in a sex-dependent manner while significantly decreased in male GHR-/- mice. Villus height, crypt depth, and muscle thickness of the small intestine were generally increased in bGH mice and decreased in GHR-/- mice compared to controls with age- and sex-dependent exceptions. Colonic crypt depth and muscle thickness in bGH and GHR-/- mice were significantly altered in an age- and sex-dependent manner. Fibrosis was increased in the small intestine of bGH males at 4 months of age, but no significant differences were seen between genotypes at other timepoints. CONCLUSION: This study observed notable opposing findings in the intestinal phenotype between mouse lines with GH action positively associated with intestinal gross anatomy (i.e. length, weight, and circumference). Moreover, GH action appears to alter morphology of the small and large intestines in an age- and sex-dependent manner.

The knowledge of anatomy and imaging exams emerges as an important tool in the study of evolutionary processes of a species, in the elaboration of diagnosis, and the successful choice of the appropriate clinical and surgical procedures. Therefore, this study aims to describe the osteology of the hind limb of Sapajus libidinosus by means of gross, radiographic, and tomographic images. Four cadavers were used in the macroscopic analysis and five animals for the imaging exams, of which four were eventually euthanized and added to the macroscopic study. For imaging exams, they were kept anesthetized. All bones of the hind limb were documented, their structures were described, and compared with data in the literature from human and nonhuman primates. We have performed Student's t test for independent samples. There was no statistical difference between the sexes regarding the length of the hind limb bones. The coxal bone was largely well described using imaging methods. A small penile bone was present at the tip of the penis and it could be identified by all analysis methods. The femur, as well as the tibia and fibula, were not well portrayed in their proximal and distal epiphyses by radiography (Rx). However, they were well identified on tomography. No third trochanter was observed in the femur and the patella had a triangular shape. All the structures described by gross anatomy of the tarsus and metatarsus could be identified by Rx and tomography. More subtle structures, such as the popliteal notch on the tibia, and the gluteal tuberosity pectineal line and facies aspera on the coxal bone, were not identified by medical imaging. S. libidinosus presented anatomical characteristics that were similar to those of larger New World and Old World monkeys, including man. This suggests it's value as an experimental model for studies in recent primates.

BACKGROUND: As ultrasound has become increasingly prominent in medicine, portable ultrasound is perceived as the visual stethoscope of the twenty-first century. Many studies have shown that exposing preclinical students to ultrasound training can increase their motivation and ultrasound competency. However, few studies have discussed the effect of ultrasound training on anatomy learning. METHOD: The Parallel Ultrasound Hands-on (PUSH) course was designed to investigate whether or not ultrasonography training affects anatomy knowledge acquisition. The PUSH course included anatomical structures located in the chest and abdomen (target anatomy) and was conducted in parallel to the compulsory gross anatomy course. Learners (n = 140) voluntarily participated in this elective course (learners in the course before the midterm examination (Group 1, n = 69), or after the midterm examination (Group 2, n = 71)). Anatomy examination scores (written and laboratory tests) were utilized to compare the effects of the PUSH course. RESULT: Group 1 obtained significantly higher written test scores on the midterm examination (mean difference [MD] = 1.5(7.6%), P = 0.014, Cohen's d = 0.43). There was no significant difference in the final examination scores between the two groups (Written Test: MD = 0.3(1.6%), P = 0.472). In Laboratory test, both mid-term (MD:0.7(2.8%), P = 0.308) and final examination (MD:0.3(1.5%), P = 0.592) showed no significant difference between two groups. Students provided positive feedback in overall learning self-efficacy after the PUSH course (Mean = 3.68, SD = ±0.56 on a 5-point Likert scale). Learning self-efficacy in the cognitive domain was significantly higher than that in the affective domain (MD = 0.58; P < 0.001) and psychomotor domain (MD = 0.12; P = 0.011). CONCLUSION: The PUSH course featured a hands-on learning design that empowered medical students to improve their anatomy learning.

PURPOSE: Anatomy has historically been taught via traditional medical school lectures and dissection. In many countries, practical or legal issues limit access to cadaveric dissection. New technologies are favored by students and could improve learning, complementing traditional teaching. METHODS: All students in second-year medicine at a single medical school were submitted to a novel anatomical course with digital tool exposure. We explored a new combined teaching method: a physical blackboard lesson synchronized with digital dissection, imaging and direct evaluation (BDIE). Synchronized dissection is broadcast live in the classroom and in partner medical schools. Following the course, students completed a short survey about their perception of this new anatomic clinical course. RESULTS: The survey included 183 students whom 178 completed the questionnaire, i.e., a 97% response rate. Ninety-nine percent of students thought this synchronized method useful to improve their understanding of anatomy and 90% stated it helped them retain this learning. CONCLUSION: This BDIE method, in conjunction with teaching guidelines and dissection, is highly appreciated by students who consider it helps them to acquire lasting knowledge.

PURPOSE: With the increasing significance of diagnostic imaging in clinical practice, long-term anatomical education and training is required to ensure that students can reliably distinguish anatomical structures and interpret images. To improve students' motivation and prospects for learning imaging anatomy, we developed an integrated anatomical practice program combining cadaveric dissection with cadaver CT data processing and analysis during undergraduate students' dissection courses. METHODS: Workstations imported with post-mortem CT data of dissected cadavers and various forms of clinical CT/MRI data were set in the dissection room. Medical students had free access to the imaging data during cadaver dissection, and they were challenged to process and analyze the data for submission of voluntary imaging reports on their topics of interest. Finally, we surveyed the integrated anatomical education of 481 medical students. RESULTS: The positive response rate to the integrated anatomical practice was 74.9%, and 79.4% of the students answered that this form of practice offered a suitable introduction to anatomical imaging. The usefulness of this approach in understanding the 2- to 3D arrangement of the human body and enhancing interest in anatomy was also confirmed. The submission rate of voluntary imaging reports also increased annually and is currently 97.4%. CONCLUSION: Our integrated anatomical practice only allowed students to actively browse CT images and facilitated imaging processing and analysis of their region of interest. This practice may improve students' long-term ability to analyze images and deepen their understanding. A competitive imaging contest may help improve students' motivation when they begin learning imaging anatomy.

PURPOSE: New training methods sprung up using communication technologies after the suspension imposed on Greek Universities due to restrictive measures against the COVID-19 pandemic. The current questionnaire-based study evaluates the efficacy and utility of the interactive online anatomy labs (ONALs) in assisting the assimilation of anatomy and substituting dissection labs during the pandemic. METHODS: ONALs consisting of video recorded demonstrations of dissected cadavers were developed so that real-time dialogue and interaction between tutor and students was feasible. First- and second-year medical students who were taught neuroanatomy and splanchnology and first-year dental students who were taught head and neck anatomy evaluated the ONALs. RESULTS: One hundred and sixty students participated. The 61 students (38.13%) attended the splanchnology, 58 (36.25%) the neuroanatomy, and 41 (25.63%) the head and neck anatomy course. 86.9% of the participants found the ONALs beneficial for their study. The 75.5% with previous experience of a "face-to-face" dissection replied that the ONALs cannot substitute satisfactorily "face-to-face" dissections. 63.8% replied positively to the ONALs maintenance after the pandemic. CONCLUSIONS: The study's novelty is based on the maintenance of the greater possible interaction between tutors and students during the ONALs, in contrast to the previously described usage of dissection educational videos in anatomy. Our findings reinforce the established statement that "a teaching dissection is an irreplaceable tool in anatomy education". However, the ONALs were well-received by the students and can be kept on as a supplementary teaching modality and can be proven quite useful in Medical Schools that lack cadavers.
