“…Similarly, Kikuta et al [10] reported a reduction of FA concentration in a gross anatomy laboratory from 1.39 to 0.04 ppm under conditions of total ventilation and local ventilation. There have also been many reports of the effects of measures developed to reduce indoor FA concentrations [11][12][13][14].…”

Objectives Our purpose was to clarify whether subjective symptoms of low-level formaldehyde (FA) exposure in medical students were transient or persistent and to investigate whether the allergy state changed as a result of exposure. Methods We surveyed the prevalence of medical students' subjective symptoms and their allergy state before, during, and 6 months after completion of a gross anatomy dissection course by using two self-administrative questionnaires. Students completed the first survey at the end of the anatomy course to assess symptoms before and during the course. The second survey was completed 6 months after course completion.Results The prevalence of most subjective symptoms was lower 6 months after the course than during the course. The major symptoms experienced during the course were eye fatigue, runny nose, and dry eyes. The most common symptom 6 months after the course was eye fatigue. Four students continued to experience symptoms even after course completion. Three students developed symptoms only after course completion. Forty-eight students had allergies before the course began and the severity of the allergies did not change after the course. Additionally, the prevalence of most subjective symptoms 6 months after the course was lower than before the course. The patterns of subjective symptoms in the three periods differed between male and female students; the prevalence of most subjective symptoms tended to be higher in females. Conclusions Subjective symptoms resulting from FA exposure during a gross anatomy course were transient and did not affect students' allergy states.

“…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.…”

“…The average formaldehyde concentration outside of the breathing zone of students sitting closet to the dissection table was 50 ppb (1) and inside of the breathing zone of students sitting closet to the dissection table was 405 ppb (2) (27). Instrumental approach based on environmental evaluation of 10% formaldehyde used in pathological anatomy, by an infrared gas analyser was investigated.…”

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.

“…As soluções fixadoras contêm, habitualmente, formaldeído em concentração variável. 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 .…”

“…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.
