“…Virtual microscopes have been reported to be as good as optical microscopy when it comes to learning histology [ 15 ] and their use has increased in education [ 16 ]. Digitalization also offers diverse possibilities for learning histology and two developments in this field are a three-dimensional, interactive online resource on the epithelium [ 17 ] and a virtual microscope histology laboratory for learning histotechnology [ 18 ].…”

The universities of applied sciences in Finland offer 3.5-year courses for histotechnologists and they graduate as biomedical laboratory scientist with 12 credits in histology and histotechnology. The aim of this study was to survey practicing histotechnologists about the core competencies needed by newly graduated biomedical scientists in histology and histotechnology. The data were collected in Finland in 2015. We asked 43 participants to complete a questionnaire that comprised two background questions, five open-ended questions and 38 Likert scale questions, with the responses ranging from five (strongly agree) to one (strongly disagree), and 22 (51%) responded. They stated that the most important competencies were the principles of tissue processing (mean 4.77), embedding (4.64), laboratory safety (4.57), fixation methods (4.55), cutting by microtomy (4.55), quality control of sections (4.55), fixation methods (4.55), and principles of stains (4.36). The least important competencies were quality control of molecular pathology (2.56), interpretation of immunohistological stains (2.71), use of molecular pathology (2.89), and independent dissection (2.91). The respondents stated that there were 20 stains that newly graduated biomedical laboratory scientists needed to know. The practices involving staining emerged in the open responses and four were considered to be important: Hematoxylin-Eosin (n = 18), Periodic Acid Schiff (n = 11), Alcian Blue-Periodic Acid Schiff (n = 9), and Giemsa (n = 9). The most essential tissues to identify were the histology of the alimentary track (n = 9), skin (n = 6), and liver (n = 5). The core competencies that histotechnologists felt were important for newly graduated biomedical laboratory scientists seemed to be consistent with the current curriculum.

“…A future proposal can be national digitalization in developing countries, flipped classrooms during online teaching, and interactive lecture series. Whether there is a place for 3D online teaching in developing countries is still questionable while adopting a more straightforward solution [15].…”

Aims: To assess medical students’ perception of online teaching to suggest transforming the future curriculum in low-economic countries. Study Design: Cross-sectional online interview study. Place and Duration of Study: A team of collaborators interviewed final year medical and dental students of Pakistan from 07/08/2020 till 17/09/2020. Methodology: A questionnaire was developed based on open and close-ended questions in Google forms; focusing on institutional preparedness, views on online education, the institute’s closure and COVID-19, and long-term effects of closure of the institute. Independent fellow researchers systematically analyzed the unaltered transcripts of the responses, and themes were then identified and coded to conclude the results. SPSS version 23 used for analysis. As this study was based on final year students. Results: In response to an invitation email, 2442/2661 (91.77%) students voluntarily participate in this qualitative study. Most participants were females (1614, 66.10%). Closing down institutes was directly linked to a lack of motivation and feel of helplessness. As most showed dissatisfaction with online teaching compounded by psychological effects, students feared losing clinical skills and life during the pandemic. Conclusion: The psychological impact of the crisis led to resistance to accepting the change for a better outcome. Incorporating telemedicine, different interactive learning style to online teaching, and resilience training would result in fruitful outcomes. Developed countries may also guide build infrastructure in developing countries to develop a more robust online teaching methodology in the long-run.

“…In addition to modeling the tissue based on histological sections only, also fusion models of histological serial sections and native 3D imaging modalities such as micro-computed tomography (μCT) [ 4 – 10 ] or magnetic resonance imaging (MRI) [ 11 – 13 ] are possible. Even manually created 3D models representing epithelium with textures acquired from histological samples have been made for teaching purposes [ 14 ]. However, applicability of 3D imaging modalities depends on the physical sample size and such measurement devices are not always available, while manual modeling from histology data is time-consuming and subjective.…”

Virtual reality for 3D histology: multi-scale visualization of organs with interactive feature exploration

et al. 2021

Background Virtual reality (VR) enables data visualization in an immersive and engaging manner, and it can be used for creating ways to explore scientific data. Here, we use VR for visualization of 3D histology data, creating a novel interface for digital pathology to aid cancer research. Methods Our contribution includes 3D modeling of a whole organ and embedded objects of interest, fusing the models with associated quantitative features and full resolution serial section patches, and implementing the virtual reality application. Our VR application is multi-scale in nature, covering two object levels representing different ranges of detail, namely organ level and sub-organ level. In addition, the application includes several data layers, including the measured histology image layer and multiple representations of quantitative features computed from the histology. Results In our interactive VR application, the user can set visualization properties, select different samples and features, and interact with various objects, which is not possible in the traditional 2D-image view used in digital pathology. In this work, we used whole mouse prostates (organ level) with prostate cancer tumors (sub-organ objects of interest) as example cases, and included quantitative histological features relevant for tumor biology in the VR model. Conclusions Our application enables a novel way for exploration of high-resolution, multidimensional data for biomedical research purposes, and can also be used in teaching and researcher training. Due to automated processing of the histology data, our application can be easily adopted to visualize other organs and pathologies from various origins.
