Background:
Pernicious Anemia (PA), the most common cause of cobalamin deficiency anemia worldwide, is an autoimmune disease of multifactorial etiologies involving complex environmental and immunological factors. Although it was first reported by Addison in 1849 with subsequent advances in understanding of pathogenesis and molecular biology, diagnosis of PA is still challenging for clinicians because of its complexity and diverse clinical presentations.
Conclusion:
Herein, we provide an overview of PA, mainly focusing on its scientific and practical aspects in diagnosis. We also discuss the limitations of currently available diagnostic tools for the evaluation of cobalamin deficiency and PA.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
