Latin American Anatomists' views on human body dissection and donation.

BACKGROUND: Studies abound regarding the medical students' views on the importance of anatomy and the dissection of human bodies, but little is known about the views of Latin American Anatomists. METHODS: A survey was carried out to test several hypotheses among anatomists of the Americas about how they perceive their professional identity, the use and role of dissection in their undergraduate courses, and the approval degree of bequeathing their body for anatomical teaching/research; another goal was ascertaining to what extent their attitude on these topics depended on gender, length of teaching experience and belief in the afterlife. RESULTS: One hundred and forty-five anatomists from thirteen Latin American and Caribbean Countries took the survey; 79% stated the main role of an anatomist is teaching; 34% recorded their undergraduate students dissected human cadavers as part of their anatomy lab course-undergraduates dissecting less in the less experienced anatomists' courses (p = 0.0002). Most anatomists said dissection was a training tool for undergraduate students, a tool for developing professional skills, and a tool to help control emotions-most experienced anatomists stood out from the rest saying dissection is only to teach anatomy (p < 0.001), even if such response was the least valued by them among all replies. Men differed from women in valuing dissection as a tool to help control emotions (p = 0.006); less experienced anatomists held the opposite (p < 0.0001). Approval of a close doctor-patient relationship diverged, being different between the most and the least experienced anatomists (p = 0.01). Anatomists said they would donate only their organs (44%), whole body (9%) and both organs and body (46%). Undecided anatomists about the belief in life after death were the least in favor of donation (p = 0.05).

18F-sodium fluoride positron emission tomography provides pertinent additional information to computed tomography for assessment and management of tarsal pain in horses.

OBJECTIVE: To assess the value of 18F-sodium fluoride (18F-NaF) positron emission tomography (PET) for imaging the tarsus and proximal metatarsus and compare it with CT and lameness evaluation. ANIMALS: 25 horses with lameness localized to the tarsal and proximal metatarsal regions that underwent 18F-NaF PET/CT between 2016 and 2021. METHODS: 18F-NaF PET and CT images were retrospectively independently evaluated by 3 observers. Standardized uptake values (SUV) were used to characterize 18F-NaF uptake. Correlation between PET and CT findings with subjective and objective maximum (Max-D) and minimum pelvic height lameness data was estimated. RESULTS: The inter-observer Kappa-weighted value (κ) was higher for PET (κ = 0.66) than CT (κ = 0.6). CT and PET scores were fairly correlated (R = 0.49; P < 0.05). PET SUVratio (SUV of the main lesion/SUV talus) had the highest correlation with Max-D (R = 0.71; P < .05). PET and CT scores for the plantar region were significantly higher in Quarter Horses (P < .05) and showed consistently higher correlation with objective lameness data (CT plantar grade - Max-D [R = 0.6; P < .05], PET plantar grade - Max-D [R = 0.47; P = .04]) than other regions of the distal tarsal joints. Three Warmbloods presented marked uptake at the medial cochlea of the distal tibia. CLINICAL RELEVANCE: PET had a moderate correlation with CT for assessment of tarsal lesions. The degree of PET uptake can help differentiate active versus inactive lesions. Specific location of the uptake is important in determining clinical relevance.

Physicians' viewpoints on faculty anatomists and dissection of human bodies in the undergraduate medical studies.

BACKGROUND: Studies abound regarding the views of faculty anatomists and medical students on the importance of anatomy and the dissection of human bodies, but very little is known about the views of practicing physicians. METHODS: A survey was distributed among physicians and surgeons practicing in Spain in order to find out their views on the practice and consequences of human dissection by undergraduate students of medicine. The most relevant definition to qualify faculty anatomists of medical schools was also requested. Responses were repeatedly clustered into characteristic subgroups for analysis. RESULTS: In total, 536 physicians and surgeons belonging to 36 different specialties in seven Spanish hospitals responded to the survey. The results highlighted two main facts. Firstly, faculty anatomists were perceived as teachers, above any other professional identity (namely: physician, biologist or scientist); nonetheless, the ascription of identities varied between specialties (p=0.009); and it also depended on whether the respondents had dissected in their undergraduate degree (p=0.03) and on the respondent's gender (p=0.03). Secondly, physicians and surgeons confirmed that dissecting human cadavers serves the undergraduate student not only for acquiring anatomical knowledge, but also essential skills and attitudes, including professionalism. CONCLUSIONS: The results strongly suggest that dissection practice should be reinforced and enriched in undergraduate medical school. As this is important in itself, the results of the study could also help with the development of strategies to alleviate the current shortage of adequately trained anatomists for medical degrees.
