“…Selected studies have shown that the levels of airbone FA in anatomy laboratories exceed recommended exposure criteria 0.05 ppm limit (3, 9,10,11,12,19,23,25,26,27,28,29,31,32,33). These are primarily caused by evaporation of formaldehyde used for the preservation of tissues and specimens.…”

Objective: Our aim is to evaluate the studies about formaldehyde exposure in anatomy laboratories at faculties of medicine all over the world reported from 2000 to 2013. Materials and Methods: In this research, formaldehyde exposure of medical students and researchers in the anatomy laboratories of faculties of medicine studies, which were reported in Pubmed database from 2000 to 2013, were reviewed and classified clinical symptoms, environmental monitoring and preventive measures. Results: There are 27 studies on formaldehyde exposure from anatomy laboratories of various faculties of medicine 15 (55.6%) of which are clinical symptom studies whereas 12 (44.4%) are environmental monitoring of formaldehyde exposure. Conclusion: Considering the fact that lower levels of exposure to formaldehyde is associated with cytogenetic changes in epithelial cells of the nasal region, long-term exposure to formaldehyde in the anatomy laboratories poses risks of nasopharynx and nasal cavity cancers. Medical students and instructors working in anatomy laboratories should take concrete measures to reduce exposure to formaldehyde.

“…A exposição a este químico tem sido associada ao desenvolvimento de doenças alérgicas, irritação das mucosas nasal e da orofaringe, cancro do pulmão e cancro da laringe [24][25][26] . Relativamente à rinite alérgica, Hisamitsu et al concluíram, através de um estudo observacional, que apenas os estudantes com antecedentes pessoais desta patologia experimentaram alterações da função olfativa e hipersensibilidade da mucosa nasal após a dissecação 25,26 . Porém, estas alterações foram transitórias 26 .…”

“…Porém, estas alterações foram transitórias 26 . Também pode ocorrer irritação ocular e cefaleias, sobretudo quando da entrada no laboratório de dissecação 25,26 . É necessário, portanto, promover medidas preventivas que reduzam a exposição dos estudantes a esta substância.…”

“…Os estudos afirmam que, em vários laboratórios de dissecação, a concentração, no ar, de formaldeído é superior aos valores máximos recomendados pela Organização Mundial de Saúde (800 ppm para locais de trabalhos em geral e 250 ppm para locais de trabalho específicos onde se manipula formaldeído) 24 . Para contornar este problema, a solução pode passar pela construção de laboratórios cuja arquitetura assegure uma melhor ventilação bem como a instalação, nas mesas de dissecação, de sistemas locais de ventilação e/ou de dispositivos que destruam o formaldeído 24,25,27 . A construção de laboratórios para este fim é um assunto que envolve, naturalmente, arquitetos, mas, também, anatomistas, dadas as suas especificidades 27 .…”

Ao longo da História, a importância da utilização de cadáveres humanos para o ensino e investigação não tem sido consensual. No passado, a obtenção dos cadáveres indispensáveis ao ensino passou pelo recurso a cadáveres de reclusos, de não reclamados e ao roubo e/ou compra. Para além da inadmissibilidade ética e jurídica destas soluções, estas revelaram-se insuficientes para as necessidades das escolas médicas. Nas últimas décadas, a consciência global da legitimidade da doação de cadáveres foi-se intensificando, considerando-se, hoje, a forma digna de colmatar essa falta. Neste artigo realizou-se uma revisão da literatura com o objetivo de se fazer uma resenha histórica, jurídica e pedagógica sobre a importância da utilização de cadáveres humanos no ensino da Anatomia Humana nos cursos de Medicina, incluindo em Portugal, nomeadamente pelo recurso à dissecação cadavérica em complementaridade com outras ferramentas pedagógicas.

Flammability and combustion hazard of preserved human tissues

Preservation techniques have evolved over the years to respond to the need of longer dissection periods, with formaldehyde being widely used for this purpose. In recent years, efforts have been focusing on reducing the health hazards of this fixative and the rigidity of the tissues embalmed with it. With every embalming technique that they are either developing or resurrecting from various protocols, institutions need to assess the fire and health hazards of all the chemicals being used. Compliance with the storage and handling safeguards listed in the Material Safety Data Sheet of each chemical, needs to be accompanied by infrastructure changes. To reduce the health hazards of formaldehyde, institutions are taking appropriate countermeasures directed at the source itself, by using substitutes or injecting formaldehyde chelating agents, and are adopting high performance air extraction systems to protect the users. However, little is known about the flammability risk of embalmed human bodies. During a recent visit to McGill University morgue by architects and safety inspectors to expand it, we were asked about the flammability risk of the embalmed specimens, so we carried out a flashpoint test to evaluate the flammability potential of specimens embalmed with each of our three embalming techniques: formaldehyde‐based, Thiel, and phenol‐based. With the phenol‐based embalming showing the most risks, attention should be drawn to all institutions who are experimenting with various embalming techniques to evaluate the flammability potential of their embalmed specimens.
