22.) A patient complains of fatigue, lack of appetite, pain and burning sensation in the
tongue, numbness of the distal limbs, diarrhea. Objectively: pale skin with lemon-
yellow tint, face puffiness, brown pigmentation in the form of a "butterfly", bright
red areas on the tongue. The liver is 3 cm below the costal margin, soft. Blood
count: RBCs - 1, 5 · 1012/l, colour index - 1,2, WBCs - 3, 8 · 109/l, thrombocytes -
180 · 109/l, eosinophils -
0%, stab neutrophils - 1%, segmented neutrophils - 58%, lymphocytes - 38%
monocytes - 3%, RBC macrocytosis. ESR - 28 mm/h. What diagnosis are these
presentation typical for?
A. B12-deficiency anemia
B. Iron deficiency anemia
C. Aplastic anemia
D. Acute erythromyelosis
E. Chronic adrenal failure
Explanation:-Vitamin B12 deficiency anemia is a low red blood cell count due to a lack (deficiency) of vitamin B12. Vitamin B12 deficiency leads to Macrocytic, megaloblastic anemia;hypersegmentation PMNs; paresthesias and subacute combined degeneration(degeneration of  dorsal column, lateral corticospinal tract and spinocerebellar tracts) due to abnormal myelin. Prolonged deficiency leads to irreversible nerve damage. 
Pernicious anemia is the most common cause of vitamin B12 deficiency
Krok 2 Medicine (Hematology) with Explanation
  •  antibody to gastric parietal cell leads to ineffective secretion of intrinsic factor (IF) 
  • leads to vitamin B12 deficiency due to decrease uptake in the terminal ilium. decrease uptake in the accompanied by achlorhydia and atrophic gastritis
    • atrophic gastritis increases risk of gastric cancer.
    • color index higher than normal I.e < 1.0

  • Symptoms can include:
    • Diarrhea or constipation
    • Fatigue, lack of energy, or lightheadedness when standing up or with exertion
    • Loss of appetite
    • Pale skin
    • Problems concentrating
    • Shortness of breath, mostly during exercise
    • Swollen, red tongue or bleeding gums
    • Symptoms of nerve damage includ:
          • Confusion or change in mental status (dementia) in severe cases
      • Depression
      • Loss of balance
      • Numbness and tingling of hands and feet

diagnosis?
A. Acute leukemia
B. Erythremia
