Pernicious anemia (also called Addison's anemia) is a type of red blood cell disorder caused by impaired vitamin B12 metabolism. Vitamin B12 is primarily absorbed by the small intestine, after being bound to intrinsic factor secreted by parietal cells of gastric mucosa. When this process is disrupted by conditions like atrophic gastritis, celiac disease, small bowel resection etc, B12 deficiency ensues.
The incidence of<unk>  myeloid leukemia (CML)  is approximately 1–2 cases per 100,000 individuals worldwide and accounts for 15% of adult leukemias. The peak age for the CML is 50 and the incidence in CML increases by age. Males are more commonly affected with CML than females.
