What is it about cold injury that kills the organs? Could I ng term exposure cause organ necrosis and kill the victim?

GivinTheColdShoulder: Your question is a bit vague. But generally, if tissue is actually frozen (frostbite), water crystals form inside the cells and that messes-up the works. When thawed, the tissue is mush. If you are talking about hypothermia, the colder you get the slower your metabolism to the point that the lack of energy formation overcomes the overall slowness of the metabolic processes and then the cells die. ...Read more

Could using steriods from chemo cause avascular necrosis?

Could using steriods from chemo cause avascular necrosis?

Possibly but others: Although avascular necrosis can be related to corticosteroids it is important to know that there are other causes of avascular necrosis.

How does prednisone cause avascular necrosis?

How does prednisone cause avascular necrosis?

Still unknown: Even though there is this very well-established connection between chronic Prednisone use and avascular necrosis, how this occurs remains unclear. Numerous hypotheses abound. Some argue that increased lipids seen with steroids cause vessels to joints to clog, leading to oxygen starvation & bone death. A more popular view is that vessel (venous) walls undergo thickening, leading to poor blood flow. ...Read more
