Chapter 1. The Head & NeckThis chapter in the Radiology-Based USMLE Board Prepbook provides medical students with an efficient, interactive resource to enhance USMLE National Board Step1 and 2 preparation and mastery. The workbook also aids students in learning clinical interpretation of computed tomography (CT) images of the head and neck. The atlas portion is also published separately as an anatomical reference for students and clinical practitioners. Contents: Three Dimensional: Skeletal System, Muscular System, Vascular System, Digestive and Respiratory Systems, Nervous System, Lymphatic. Two Dimensional: Frontal, Sagittal, Axial (All Structures), Axial (Lymphatic System). Images of Pathology: USMLE Style Questions. Age of Subject: 17 Reviewed by: Richard Gacek, MD, David Goff, MD, Alan Stark, MD, of the University of Massachusetts Medical School; Ozan Toy, BA

Gender-specific Anatomical Distribution of Internal Pudendal Artery Perforator: A Radiographic Study for Perineal ReconstructionBackground: Cancer, trauma, infection, or radiation can cause perineal defects. Fasciocutaneous flaps based on perforator vessels (PV) from the internal pudendal artery (IPA) provide an ideal reconstructive option for moderate defects. We hypothesized that, due to gender differences in the pelvic-perineal region, the anatomical distribution of PV differs between genders. Methods: Computed tomography angiographies from male and female patients without pelvic-perineal pathologies were retrospectively analyzed to study the vascular anatomy of the IPA. The number, size, type, and distribution of PV were recorded and compared between genders. Four anatomical regions were defined to describe the distribution of PV on each perineal side: anterior (A), anterior-central (AC), central-posterior (CP), and posterior (P). Results: A total of 63 computed tomography angiographies were analyzed (men, 31; women, 32). Each IPA provides 2 +/- 1 PV and 5 +/- 2 terminal (cutaneous) branches: in both genders, 85% of PV are septocutaneous (15% musculocutaneous). In women, 70.5% of PV are located in AC, 28.2% in CP, 1.2% in A, and 0% in P: average diameter of the PV is 2.4 +/- 0.3 mm. In men, 53.7% of PV are located in CP, 43.1% in AC, 3.3% in A, and 0% in P: average diameter of the PV is 2.8 +/- 0.5 mm. Gender-specific differences in anatomical distribution of PV are significant (P < 0.001). Conclusions: Number, size, and type of terminal branches of PV of the IPA are consistent between genders, but their distribution is different, with women having an anterior predominance. Knowledge of gender-specific anatomy can guide preoperative planning and intraoperative dissection in flap-based perineal reconstruction.

Google Images Search Results as a Resource in the Anatomy Laboratory: Rating of Educational ValueBackground: Preclinical medical learners are embedded in technology-rich environments, allowing them rapid access to a large volume of information. The anatomy laboratory is an environment in which faculty can assess the development of professional skills such as information literacy in preclinical medical learners. In the anatomy laboratory, many students use Google Images searches in addition to or in place of other course materials as a resource to locate and identify anatomical structures. However, the most frequent sources as well as the educational quality of these images are unknown. Objective: This study was designed to assess the sources and educational value of Google Images search results for commonly searched anatomical structures. Methods: The top 10 Google Images search results were collected for 39 anatomical structures. Image source websites were recorded and categorized based on the purpose and target audience of the site publishing the image. Educational value was determined through assessment of relevance (is the searched structure depicted in the image?), accuracy (does the image contain errors?), and usefulness (will the image assist a learner in locating the structure on an anatomical donor?). A reliable scoring rubric was developed to assess an image's usefulness. Results: A total of 390 images were analyzed. Most often, images were sourced from websites targeting health care professionals and health care professions students (38% of images), while Wikipedia was the most frequent single source of image results (62/390 results). Of the 390 total images, 363 (93.1%) depicted the searched structure and were therefore considered relevant. However, only 43.0% (156/363) of relevant images met the threshold to be deemed useful in identifying the searched structure in an anatomical donor. The usefulness of images did not significantly differ across source categories. Conclusions: Anatomy faculty may use these results to develop interventions for gaps in information literacy in preclinical medical learners in the context of image searches in the anatomy laboratory.

Population representation among anatomical donors and the implication for medical student educationDissection provides a unique opportunity to integrate anatomical and clinical education. Commonly, cadavers are randomly assigned to courses, which may result in skewed representation of patient populations. The primary aim of this study was to determine if the anatomical donors studied by students at the University of Massachusetts Medical School (UMMS) accurately represent the disease burden of the local patient population. This cross-sectional study compared the University of Massachusetts Memorial Medical Center patient claims data and body donation data from the UMMS Anatomical Gift Program (AGP). This study examined age, race, sex, and morbidities within a 10-year timeframe in 401,258 patients and 859 anatomical donors who met inclusion criteria. An independent t test was conducted to compare the mean ages of the two populations. Chi square analysis was conducted on race, sex, and 10 morbidity categories. A Fischer's exact test was conducted for two morbidity categories with n < 10. Demographic analysis showed a significant difference in age, and racial representation between the populations. No statistical difference was found regarding sex. Morbidities were separated into 22 ICD-10 categories. Twelve categories were excluded and 10 were analyzed for population comparison. Two categories were over represented and seven were under-represented in the AGP population. One category showed no significant difference between populations. Targeted selection of cadavers in anatomy courses would improve morbidity variability in the anatomy lab. In addition, AGP acceptance guidelines should be evaluated to increase disease variation among the donor population.
