History note: tragedy of Thorotrast

History of the use and toxicity of thorotrast.

In Lisbon, Professor Egaz Moniz, Nobel Prize laureate in medicine for 1945, pioneered the introduction and use of Thorotrast particularly for the visualization of arteries. He produced a large number of excellent publications which contributed, within 2 to 3 years of its first production, to its widespread adoption throughout Europe, Japan and North America. Moniz was not alone in this pioneer ...

A Note on Funaki and Yamato’s Tragedy of the Commons

In the model of Funaki and Yamato (1999) the tragedy of the commons can be avoided with pessimistic players, while this does not hold for optimistic players. We propose a new core concept to overcome this puzzle and provide numerical simulations of simple games where the conclusions coincide or are less sensitive to behavioural assumptions.

Long-term hazards of Thorotrast.

As regards changes which could lead to irreversible lowering of cardiac function, the arteritis might prove in the long run the most significant if it progressed. There is no evidence in the affected vessels of obstructive phenomena at the time of the patient's death and no effects on the myocardium were noted. It would seem reasonable to infer that if this necrotizing arteritis was a manifesta...
