What do you do when you see purple or dark tissue? |
|
Definition
Recognize that it is not healthy. Take it out. |
|
|
Term
|
Definition
Due to lack of intrinsic factor. Atrophied gastric mucosa will not be able to liberate B12 rom food due to a decrease of pepsin and acid, will cause decrease in DNA synthesis. Most common type of anemia. |
|
|
Term
What type of B12 deficiency is common in the elderly? |
|
Definition
Atrophy of the gastric musoca called food-cobalamin malabsrption. Clinical signs and symptoms are less severe due to its slow development. Lack of B12 will lead to a defect in DNA synthesis, especially in cells with rapid turnover, like blood cells, which leads to anemia. |
|
|
Term
Why does B12 deficiency cause nerve damage? |
|
Definition
It is an important cofactor in converting homocysteine to methionine. Methionine is needed for production of choline-containing phospholipids which are formed in the myelin sheath of nerves. Without phospholipids, nerve transmission is impaired. |
|
|
Term
Spinal Cord and B12 deficiency |
|
Definition
Lack of phospholipids in myelin sheaths causes "subacute combined degeneration of the spinal column", affects the posterior and lateral columns of the spinal cord. Posterior column transmits vibration and position sense. Lateral column coordinates voluntary movement-disorders and will cause stroke-like symptoms. |
|
|
Term
Treatment of B12 deficiency |
|
Definition
Monthly IM injections 1000 micrograms of B12 or daily oral crystalline B12 at a dose of 1000-2000 micrograms. Nromal daily requirement is 3 micrograms/day. Oral is effective because 1-5% of cobalamin absorbed passively along the intestine and does not need an intrinsic factor. |
