ABSTRACT
Introdução: Fatores de risco associados ao trabalho podem causar, entre outros, câncer de colo uterino. Objetivo: Identificar na literatura especializada a associação entre câncer de colo de útero e a exposição aos fatores ocupacionais de risco. Métodos: Realizou-se um levantamento bibliográfico em bases de dados eletrônicos com os seguintes descritores: câncer de colo uterino e riscos ocupacionais. Resultados: Trabalhadores expostos ao tabaco nas fábricas de cigarro, fluidos de motores, exposição ocupacional a fungos e bactérias e ao tetracloroetileno, presente em produtos de limpeza usados em lavanderias e para desengraxar metais, estariam mais susceptíveis ao desenvolvimento de câncer de colo uterino. Conclusão: Há poucos estudos que identificam a relação entre o câncer de colo de útero e os fatores de risco ocupacional, dificultando a associação entre o carcinogênese e o fator de risco.
Background: Occupational risk factors are associated with many types of neoplasms including cervical cancer. Objective: To review the specialized literature for evidence on the relationship between cervical cancer and exposure to occupational hazards. Methods: Literature search in electronic databases using keywords cervical cancer and occupational risk. Results: Workers occupationally exposed to tobacco, fungi or bacteria, metalworking fluids and tetrachloroethylene used in dry cleaning and for metal degreasing exhibited higher susceptibility to cervical cancer. Conclusion: Few studies sought to investigate relationships between cervical cancer and occupational hazards, which hinders the attempts at establishing a causal link.

La neurotoxicidad es un grave problema de salud pública debido al incremento de sustancias neurotóxicas y a la gran cantidad de trabajadores expuestos. Gran cantidad de sustancias de uso común en la industria. Tales como solventes, metales y plaguicidas, provocan alteraciones neurotóxicas a concentraciones por debajo de los límites permisibles, produciendo cambios importantes en la función psicológica y el comportamiento, que se expresan en trastornos funcionales que interfieren en las tareas cotídianas e incrementan la accidentabilidad. En este artículo se revisa la literatura científica sobre los efectos neurotóxicos de solventes, plomo, mercurio y plaguicidas, y se comentan aspectos metodológicos de interés para el diseño de investigaciones epidemiológicas. Como conclusión, es notoria la existencia de evidencias que demuestran el efecto neurotóxico de gran cantidad de sustancias usadas en la industria. Así mismo, consideramos importante continuar realizando investigaciones sobre el tema, y sobre todo, La necesidad de tomar medidas preventivas para proteger la salud del trabajador

By the nature of their work environment, physicians may be exposed to potentially toxic substances that can trigger chemical sensitivity. Nineteen physicians with chemical sensitivity were evaluated at the Environmental Health Center - Dallas regarding: type of specialty, history of chemical exposure, symptoms produced, food and water tolerance, immune parameters and double-blind chemical inhalation challenge. Food and chemical sensitivities were demonstrated in these physicians by oral, intradermal and inhalation challenges. After treatment, fifteen of the nineteen physicians were able to resume medical practice. Potential sources of chemical exposure in medical environments are evaluated.
