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.
Collapse of the vertebral body secondary to ischemic necrosis results in an overall decrease in the volume of bone with associated intraosseous cleft formation (5). Generated low pressure in these clefts allows accumulation of gas, which produces the intraosseous âvacuumâ phenomenon of the vertebral collapse (1,5).
