HHNKC is also known as diabetic hyperglycemic hyperosmolar coma (HHOC), hyperosmolar nonketotic coma (HONK), hyperosmolar hyperglycemic state (HHS) or hyperosmolar hyperglycemic nonketotic syndrome (HHNS). In HHNKC, blood sugar levels rise, and your body tries to get rid of the excess sugar by passing it into your urine.
Pressures sores result from the death (necrosis) of tissues due to local deprivation of blood supply, and thus of oxygen (ischemic necrosis). This is why tissue compression is the first clinical sign of pressure sores; it blocks the small blood vessels supplying tissues.
Written By: Necrosis, death of a circumscribed area of plant or animal tissue as a result of disease or injury. Necrosis is a form of premature tissue death, as opposed to the spontaneous natural death or wearing out of tissue, which is known as necrobiosis. Necrosis is further distinguished from apoptosis, or programmed cell death, which is internally regulated by cells, plays a critical role in embryonic development, and serves as a protective mechanism against disease and other factors.
