AbstractAbstract PDF
Agranulocytosis is a rare complication of antithyroid drug therapy. Neutropenic enterocolitis is characterized by neutropenia plus cecal and ascending colon inflammation, and this is the most feared side effect of agranulocytosis. This is a rare complication of chemotherapy for treating hematological malignancies and less commonly, of the medication used for treating other diseases (e.g., hyperthyroidism). The mortality rate varies from 50 to 100%, with most deaths being due to bowel perforation and sepsis. Therefore, early recognition and proper medical management of neutropenic enterocolitis is important. Recently, early recognition and progress in the management have probably reduced the mortality of this malady, yet there have been no prospective randomized trials or high-quality retrospective studies on the treatment of neutropenic enterocolitis. Therefore, standardized recommendations concerning the indications for surgery cannot be made, but most of these patients are probably not candidates for surgical intervention. Non-surgical management may be a reasonable initial approach for those patients presenting without significant complications such as peritonitis, perforation or bleeding. We report here on a case that was treated with successful medical management for neutropenic enterocolitis that occurred when administering methimazole therapy as an antithyroid drug.

AbstractAbstract PDF
Autoimmune diseases are occasionally associated with other autoimmune diseases in the same patients. Autoimmune Graves' disease has been associated with systemic rheumatic diseases including systemic lupus erythematosus (SLE). And Graves' disease associated with idiopathic thrornbocytopenic purpura (ITP) has been reported many times in Korea. There is a special relationship between SLE and ITP, both of which are autoimmune diseases. Some patients with thrombocytopenic purpura, labeled as idiopathic at the onset, later develop a classical course of SLE, suggesting that ITP may be an early manifestation of SLE. The relationships among these three conditions and their pathogenesis are poorly undemtood, and the coexistence of these diseases at the same time has been reported very rarely, but it may be very probable that there are some relationships among them. We report a case of SLE associated with Graves' disease and ITP treated well by imunosup-pressive agent who had been suffering from recurrence by conventional treatments (antithyroid medication, corticosteroid, subtotal thyroidectomy and splenectomy).

AbstractAbstract PDF
Primary hyperparathyroicism is a state of hypersecretion of PTH by the parathyroid. The etiology has not been established. The three possible etiologies of piimary hyperparathyroidism and incidences are adencena(83%), hyperplasia(15%), and carcinoma(1~2%). Parathyroid carcinoma usually presents in the fourth decades. The hallmark preoperative signs are hypercalcemia(serum calcium 15mg/dl). Palpable neck mass and bane and renal disease. Patients may present with multiple signs and syrnptoms, including recurrent nephrolithiasis, peptic ulcers, mental change, less frequently, extensive bone resorption. However, with greater awareness of the disease and wider use of screening tests, including blood calcium determinations, the diagnosis is frequently made in patients who have no symptoms and minimal, if any, signs of the disease ather than hypercalcemia and elevated levels of parathyroid Hormone. An 38-years-old woman was admitted to the hospital due to pain on the left knee joint. We experienced full-brown symptom pertaining to hyperpara- thyroidism. Thus we report a case herein and also discuss clinical anifestation, histologic features and treatment.
