RESUMO

Pernicious anemia is the frequent cause of megaloblastic anemia, and it is the result of a vitamin B12 deficiency due to the decrease or absence of intrinsic factor (IF) because of gastric mucosa atrophy or autoimmune destruction of IF-producing parietal cells. With the existence of a severe gastric atrophy, there is a decreased in acid and IF production and a further change in vitamin B12 absorption. Mercury is ubiquitous in nature and exists in 3 forms, elemental mercury, inorganic salts and organic compounds. Organic forms, specifically methyl mercury, are the most toxic of the 3 classes of mercurials. Methyl mercury exerts its most devastating effect on the central nervous system by causing psychiatric disturbances, ataxia, visual loss, hearing loss, and neuropathy. We report a case of mercury intoxication associated with pernicious anemia. The 77 years old patient was referred to Yeungnam University Hospital for tongue pain, somatitis, headache and aggressive behavior. He had taken an unevaluated medicine for a long time. After clinical evaluation, this case was diagnosed as a pernicious anemia and the unevaluated medicine was made up of mercury. After the administration of D-penicillamine and intramuscular injection of BAL and cobalamine, clinical symptoms and aggressive behavior were improved as well as laboratory findings.

RESUMO

Central diabetes insipidus (DI) is a syndrome characterized by thirst, polydipsia and polyuria. Langerhans cell histiocytosis is one of the etiologies of DI. Recently we experienced a central DI associated with Langerhans cell histiocytosis. The 44 years old female patient complained right hip pain, polydipsia and polyuria. We carried out water deprivation test. After vasopressin injection, urine osmotic pressure was increased from 109 mOsmol/kg to 327 mOsmol/kg (300%). Brain MRI showed a thickened pituitary stalk and air bubble like lesions sized with 5cm, 7cm was shown on fifth L-spine and right hip bone at hip bone CT. CT guided biopsy revealed abnormal histiocytes proliferation and abundant lymphocytes. The final diagnosis was central DI associated with systemic Langerhans cell histiocytosis invading hip bone, L-spine and pituitary stalk. Desmopressin and etoposide chemotherapy were performed to the patient.
