BACKGROUND
High-resolution ultrasonography has made the detection of asymptomatic small thyroid possible. Recent increases in the detection of incidentalomas have created a clinical dilemma on how to properly manage such incidental nodules. We investigated the prevalence, clinical and ultrasonographic characteristics, and optimal diagnostic approach toward incidentally detected benign and malignant thyroid nodules of less than 1.5 cm in size. METHODS: A retrospective review was undertaken on the 1,475 patients who had visited Samsung Medical Center, Seoul Korea between January 1999 and December 2000. The review consisted of a physical examination of the thyroid gland, thyroid function test, antithyroid antibodies, thyroid ultrasonography, fine-needle aspiration biopsy, pathology and TNM staging of the incidentally detected thyroid nodules of less than 1.5 cm in size. RESULTS: The prevalence of thyroid incidentalomas was 13.4% and the malignancy rate within them was 28.8%. There were no significant differences in age, sex, thyroid function test and size between the benign and malignant incidentalomas. Ultrasonographic characteristics showed meaningful diagnostic value for the detection of malignancy in incidentalomas. Most malignant incidentalomas were of a low stage. CONCLUSION: Occult thyroid cancers are fairly common finding. There are no clinical difference between benign and malignant thyroid nodules less than 1.5 cm ; however, ultrasonographic fingings can be used to decision of optimal management strategies.

AbstractAbstract PDF
Secondary diabetes mellitus caused by increased growth hormone secretion (GH) has well been known. There is a close association between glucose intolerance and GH secretion, and increased GH level itself probably worsens the blood glucose control and lipid profile by increasing glycogenolysis and / or gluconeogenesis and by suppressing lipase activity. We report a case of acromegaly with diabetic ketoacidosis as and hypertriglyceridemia-induced acute pancreatitis. A 38 year old male, previously diagnosed to have acromegaly and diabetes, presented with nausea, vomiting, diffuse abdominal pain and altered mentality. There was no history of drug or alcohol consumption, blood gas analysis showed severe acidosis and urinanalysis for ketone was positive. His serum blood glucose, amylase and lipase levels were 494 mg/dL, 331 U/L, and 1288 U/L, respectively (reference values: 70~110 mg/dL, 13~100 U/L and 13~190 U/L, respectively). The patient was diagnosed as having diabetic ketoacidosis and acute pancreatitis. With the serum concentration of triglyceride being 1488 mg/dL and the absence of any obvious precipitating factors, we considered hypertriglyceridemia to be the cause of acute pancreatitis. He was treated with continuous intravenous insulin infusion, lipid lowering agent, and fluid replacement. After conservative management, general condition gradually improved and his serum amylase, lipase and triglyceride levels were all normalized. GH level was not suppressed under 2 ng/mL during oral glucose loading test, and basal GH and IGF levels were 231 ng/mL and 29.5 ng/mL, respectively. Sella MRI showed a 3.7 cm sized pituitary mass. On the 55th day of admission, transsphenoidal surgery was performed. In immunohistochemical staining, the pathologic tumor specimen was proved to be GH positive pituitary adenoma. This is the first case reported in the English literature of an acromegaly presenting with diabetic ketoacidosis and acute pancreatitis
