- Syndrome of inappropriate antidiuretic hormone is the most common cause of hyponatremia in hospitalized patients. It is defined as retention of water, loss of sodium and inappropriately concentrated urine in euvolemic patients with normal renal and adrenal function. A 26-year old male was admitted due to weight loss and fever that he had experienced for the previous 1 month. The chest X-ray and CT scan of lung showed about 2.5x1.2 cm lymph node enlargement at the left hilum and multiple lymph node enlargements. Thoracoscopic biopsy revealed tuberculosis. During treatment with antituberculosis drugs, the serum sodium was 125 mEq/L, the serum osmolality was 263 mOsm/kg, the urine osmolality was 577 mOsm/kg, and the urine sodium concentration was 177 mEq/L. He was treated by fluid restriction and hypertonic saline infusion, but he did not improve. Brain CT scan showed tuberculous meningitis with hydrocephalus. He fully recovered after undergoing ventriculoperitoneal shunt. We report here on a case of inappropriate antidiuretic hormone syndrome complicated by tuberculous meningitis that was refractory to antituberculosis drugs.

- Ectopic ACTH syndrome is frequently caused by lung cancer and uncommonly by other tumors such as thymic carcinoid. For its treatment, early diagnosis and complete resection is irresponsible, but some cases are remained unlocalized in spite of all diagnostic modalities. Here we report a case of ectopic ACTH syndrome which was localized by PET but could not be localized by conventional technique. A tumor at thymic area was ACTH secreting thymic carcinoid which was operated but couldnt resect completly. Glucocorticoid hypersecretion was persisted with chemotherapy, radiotherapy, and ketoconazole treatment. Patient died of sepsis after 12 months of diagnosis.

- Isolated ACTH deficiency is a rare disorder, and usually characterized by its chronic course. The 59 year-old woman patient who had been healthy until 2 months ago, admitted because of abdomial pain, general weakness and loss of weight about 12kg for 2 months. She looked a little pallor but color of skin was not remarkable. Blood pressure, serum electrolyte, and glucose on admission were within normal range. Serum calcium was elevated with the value of 12.6mg/dL, which was normalized after hydration. Cortisol response to RI induced hypoglycemia did not show any response. Anterior pituitary hormone except ACTH showed normal response during combined pituitary hormone stimulation test. These clinical and laboratory finding reveals that isolated ACTH deficiency was developed in a short term period. There were no abnormalities in sellar MRI except pineal cyst. Her complaints were disappeared dramatically after hydroccetisone replacement at 4th. hospital day. Here we report a case of isolated ACTH deficiency, which was rapidly developed, with hypercalcemia, abdominal pain, and loss of weight about 12kg for 2 months.

- BACKGROUND
Rapid adrenocorticotropin (ACTH) stimulation test using 250ug of ACTH (1-24) has been used as a standard test in the initial assessment of adrenal function. However, it has recently been suggested that a rnaximal cortisol response can be achieved with a much lower ACTH dose, and reducing the dose might further enhance the sensitivity of the test in the detection of mild adrenal insufficiency. This study was performed to evaluate the role of low-dose (lug) ACTH stimulation test in the assessment of adrenal function and the diagnosis of subtle adrenal insufficiency. METHODS: Twenty-two subjects with suspected adrenal insufficiency due to long-term corticosteroid use were included in this study. The correlations between clinical features and the serum cortisol responses to low dose (lug) and high dose (250 ug) ACTH stimulation were evaluated. RESULTS: In high dose test, 10 (67%) out of 15 subjects with clinical features of adrenal insufficiency showed decreased serum cortisol response (peak cortisol level <18 ug/dL), but 5 (33%) subjects showed normal response (peak cortisol level > 18ug/dL). On the other hand, 14 (93%) subjects with clinical features of adrenal insufficiency showed decreased serum cortisol response in low dose test, while only one showed normal response. In 7 subjects without clinical features of adrenal insufficiency, 5 subject (71%) showed normal response, and 2 subjects (29%) showed decreased response in both low and high dose tests. CONCLUSION: These results suggest that the 1-ug low dose ACTH stimulation test might be more sensitive than conventional 250-ug test in the detection of mild adrenal insufficiency. Further studies are needed to determine the optimal dose of ACTH and the criteria for normal response to ACTH stimulation.

Abstract

- Nesidioblastosis is a primarily childhood disease which is often associated with hyperinsulinemic hypoglycemia. It is very rarely found in adults. Only a few well documented cases are found in the world interature. The authors have recently experienced a case of nesidioblastosis in an adult. A 55-year-old man was admitted due to repeated episodes of reversible loss of consciousness. Hyperinsulinemic hypoglycemia was documented. Under the presumptive diagnosis of insulinoma, localization procedures were done but no definite tumor was found. Only suspicious gradient in insulin concentration was found around the head of pancreas by percutaneous transhepatic portal venous sampling. Exploratory laparotomy was performed and Whipple's operation was done. Seventy percent of proximal pancreas was removed. Histomorphometric study of the resected specimen revealed uneven graded hyperplasia of the islet cells with the most profuse hyperplasia in the head region and progressive decrease in the degree of hyperplasia to the body and tail. The patient remains euglycemia until 6 months after operation since immediate postoperative period and can tolerate 24 hour fasting without any medication.
