Epidemiology Work (II)

The etiological role that occupational exposures may play in development disease, injury and premature death was identified long ago and is part of the history of epidemiology. In 1700, Bernardino Ramazzini, the founder of occupational medicine and one of the first to revive and expand the Hippocratic tradition according to which health depends on natural external factors, wrote in his "De morbis artificum Rant ( Ramazzini 1705; Saracci 1995):
The doctor has to ask many questions to their patients. On affections Hippocrates says: "A sick person should ask you what hurts, why, for many days, what you eat and how are their droppings. All these questions should be added another: What works? "
This resurgence of clinical observation and attention to the circumstances surrounding the occurrence of disease carried Ramazzani to identify and describe many of the diseases most would later be studied by medical and epidemiological work.
Using this approach, Pott was first suggested in
1775 (Pott 1775) the possible relationship between cancer and a profession (Clayson 1962). His observations on cancer of the scrotum in chimney sweeps began with a description of the disease and continued:
The fate of these people is particularly bleak: in childhood tend to receive brutal treatment and, if not die of hunger and cold, are forced to enter narrow-chas fireplaces, some of them still warm , which suffered bruises, burns and suffocation. When they reach puberty, are particularly prone to develop one of the most vexing diseases, painful and deadly. On this latter circumstance, and there is no doubt, but perhaps it was not given sufficient attention to make it known. Other people develop cancer in those same body parts, but so does the colic of Poitou and the resulting paralysis, which affects other people as well as lead workers, although they are particularly prone to the disease, and so do the sweeps for cancer of the scrotum and testicles.
