The design and production of 3D printed tags described here offers a unique ability to design in factors that support students with visual and learning disabilities. The lack of commercially available tags that can withstand the rigors and chemical exposure within this specific environment make the creation of this novel intervention vital to a great number of facilities. This report outlines the iterative process in creating a successful tag and the specifications needed to repeat the project. The success of these tags will impact students for years to come.

Tortuous blood vessels can cause nerve compression, as well as present difficulties to surgeons and radiologists. Here we present an unusual case of multi-vessel arterial tortuosity discovered in 78-year-old Hispanic male cadaver, independent of systemic pathology. The left ulnar and right tibial arteries were dissected, and using calibrated digital calipers, their external and internal diameters were measured both at the origin site and at the site of greatest dilation. Both wall thickness and the number of inflection points were also measured. Six bends were noticed in the ulnar artery and its diameter measured 8.11 mm at its widest, with a wall thickness of 0.88mm. On the lower extremity, the right tibial artery had three bends and its diameter measured 4.86 mm at its widest, with a wall thickness of 1.32 mm. This uncommon tortuosity is not only mor...

The incorporation of images in the Digital Imaging and Communications in Medicine (DICOM) format has been hindered by the lack of integrated, DICOM image-compatible, viewing software. Background A project was developed to facilitate the migration of clinical diagnostic radiology images, in their native DICOM format into the curriculum at the undergraduate level, including the Medical School, while anonymizing the images and presenting them in a way that simulates a clinical Picture Archive and Communication System (PACS). These images can be directly incorporated into Blackboard Learn or into other applications using embedded URLs. Discussion A teaching file server was deployed using the Medical Imaging Resource Community-Teaching File System (MIRC-TFS) platform. An HTML5, DICOM image viewing server was developed and deployed. Plugins were created to integrate the anonymized images in the MIRC-TFS server with the HTML5 DICOM viewer and Blackboard Learn. The solution was deployed at an undergraduate level. Conclusion This project has resulted in the successful development and deployment of a variety of solutions, including an HTML 5 DICOM viewer, that has allowed for the incorporation of anonymized DICOM images from a clinical imaging repository into the undergraduate curriculum.

Imbalances in remodeling, for example, are linked to bone disease, including fragility associated with aging. We have reported that there is a reduction in scale for one component of the LCN, osteocyte lacunar volume, across the human lifespan in females. In the present study, we explore the hypothesis that canalicular porosity also declines with age. To visualize the LCN and to determine how its components are altered with aging, we examined samples from young (age: 20-23 y; n = 5) and aged (age: 70-86 y; n = 6) healthy women donors utilizing a fluorescent labelling technique in combination with confocal laser scanning microscopy. A large cross-sectional area of cortical bone spanning the endosteal to periosteal surfaces from the anterior proximal femoral shaft was examined in order to account for potential trans-cortical variation in the LCN. Overall, we found that LCN areal fraction was reduced by 40.6% in the samples from aged women. This reduction was due, in part, to a reduction in lacunar density (21.4% decline in lacunae number per given area of bone), but much more so due to a 44.6% decline in canalicular areal fraction. While the areal fraction of larger vascular canals was higher in endosteal vs. periosteal regions for both age groups, no regional differences were observed in the areal fractions of the LCN and its components for either age group. Our data indicate that the LCN is diminished in aged women, and is largely due to a decline in the canalicular areal fraction, and that, unlike vascular canal porosity, this diminished LCN is uniform across the cortex.

If not, medical students are missing the opportunity of experiencing normal variation within the population, which may promote bias in their clinical years. This cross-sectional study compared data from the UMMS Anatomical Gift Program (AGP) with the Health and Retirement Study (HRS) population data. This study examined sex, race, ethnicity, veteran status, and sexual orientation. 5 years (n=540) of AGP data and 3 waves (n=5,037) of HRS data were examined. The results demonstrate that sex differences between the AGP and HRS populations (55% for females vs. 45% for males; p=.10) are NOT significant. A significant racial difference between populations is noted (p=.000), with 98.3% of the AGP vs. 72.7% of the HRS identifying as white. Veterans are overrepresented in the A...

networks of Haversian systems in human cortical bone in order to observe and analyse
interconnectivity of Haversian systems and the development of total Haversian networks across different ages.
A better knowledge of how Haversian systems interact with each other is essential to improve understanding
of remodeling mechanisms and bone maintenance; however, previous methodological approaches (e.g. serial
sections) did not reveal enough detail to follow the specific morphology of Haversian branching, for example.
Accordingly, the aim of the present study was to identify the morphological diversity of branching patterns
and transverse connections, and to understand how they change with age. Two types of branching
morphologies were identified: lateral branching, resulting in small osteon branches bifurcating off of larger
Haversian canals; and dichotomous branching, the formation of two new osteonal branches from one. The
reconstructions in this study also suggest that Haversian systems frequently target previously existing systems
as a path for their course, resulting in a cross-sectional morphology frequently referred to as ‘type II osteons’.
Transverse connections were diverse in their course from linear to oblique to curvy. Quantitative assessment
of age-related trends indicates that while in younger human individuals transverse connections were most
common, in older individuals more evidence of connections resulting from Haversian systems growing inside
previously existing systems was found. Despite these changes in morphological characteristics, a relatively
constant degree of overall interconnectivity is maintained throughout life. Altogether, the present study
reveals important details about Haversian systems and their relation to each other that can be used towards a
better understanding of cortical bone remodeling as well as a more accurate interpretation of morphological
variants of osteons in cross-sectional microscopy. Permitting visibility of reversal lines, synchrotron radiationbased
micro-CT is a valuable tool for the reconstruction of Haversian systems, and future analyses have the
potential to further improve understanding of various important aspects of bone growth, maintenance and
health.
