Abstract PDF: Primary hyperparathyroidism is caused mainly by a parathyroid adenoma or hyperplasia, and is characterized by hypercalcemia and hypophosphatemia induced by an increased level of parathyroid hormone (PTH). Patients with primary hyperparathyroidism are usually asymptomatic and the disease is most often detected incidentally. However, patients can present with symptoms of renal stones, peptic ulcer disease, muscle weakness, depression, constipation, and pancreatitis. In addition, it has been reported that choletithiasis can be combined with primary hyperparathyroidism. We report a case of a 49-year-old man with primary hyperparathyroidism accompanied with chronic cholecystitis caused by a gallbladder (GB) stone. The chief complaint was nausea, poor oral intake, abdominal pain, and weight loss. Abdominal sonography was performed and chronic cholecystitis with a GB stone was diagnosed. The serum calcium level was 18.5 mg/dL and the intact parathyroid hormone level was 1,777 pg/mL. A parathyroid mass was detected by neck-computed tomography, neck ultrasonography and a (99m)Tc-Tetrofosmin parathyroid scan. The parathyroid mass was removed and the mass was confirmed as a parathyroid adenoma. Cholecystectomy was performed and the diagnosis of chronic cholecystitis was confirmed. After the surgical procedure, the symptoms improved and the calcium level was normalized.

Abstract PDF

Subclinical Cushing's syndrome is defined as an autonomous cortisol hyperproduction without specific clinical signs of cortisol excess, but detectable biochemically as derangements of the hypothalamic-pituitary-adrenal axis function. We report a case of a 33-year-old woman with subclinical Cushing's syndrome caused by left adrenocortical adenoma, mistaken for Liddle's syndrome. The patient complained of fatigue. Laboratory findings showed metabolic alkalosis, hypokalemia, high TTKG (transtubular K concentration gradient), low plasma renin activity, and low serum aldosterone level, that findings implied as Liddle's syndrome. So we performed further study. Hormonal and radiologic studies revealed subclinical Cushing's syndrome with a left adrenal mass. The adrenal mass was resected and pathologically diagnosed as adrenocortical adenoma. After the resection of the left adrenal mass, patient's hormonal levels showed normal range.

Abstract PDF: BACKGROUND
Cardiovascular disease is the leading cause of death in postmenopausal women. The use of hormone replacement therapy (HRT) preventing for cardiovascular disease in postmenopausal women remains controversial. We investigated the effect of HRT on carotid intima-media thickness (IMT) according to the HRT duration in healthy postmenopausal women. METHODS: One hundred and twenty postmenopausal women (mean age: 55.4 +/- 3.3 years) were classified into never users, short-term, and long-term users according to the HRT duration. Carotid IMT was measured, and the clinical and biochemical cardiovascular risk factors were examined. RESULTS: The mean IMT was significantly thinner in the long-term users than that in the never users (0.62 +/- 0.11 vs. 0.71 +/- 0.14 mm, P < 0.01). Also, the maximal IMT was significantly thinner in the short-term and the long-term users. However, there is no significant difference in the mean and maximal IMTs between the estrogen alone and estrogen plus progestins used group. The period exposed to menopause was significantly shorter in the long-term users than that in the never users (1.8 +/- 2.3 vs. 4.3 +/- 3.3 years, P < 0.001). CONCLUSION: Our findings suggest that if HRT is initiated during early postmenopausal period before the onset of atherosclerosis, HRT may have a beneficial effect on the prevention of carotid atherosclerosis.

Abstract PDF: Although calcification of such endocrine gland as adrenal or pineal gland is common, extensive calcification of the pituitary gland is unusual. Calcification is a well recognized but uncommon feature of prolactin-secreting, growth hormone-secreting and non-functioning pituitary tumours. The calcification varies in extent, but rarely exceeds a tiny amount histologically or radiologically. Recently, we had the opportunity to investigate two patients with radiologically demonstrated "pituitary stone" (severely calcified pituitary adenoma). The first Patient, a 51 year-old female, initially presented with general weakness, dizziness, visual disturbance, and loss of hair for 2 months. She was suspected to have a pituitary lesion. Decreased secretion of GH, TSH, LH, and FSH was demonstrated by dynamic tests. On CT scan, she was found to have multilobulated calcified sella mass. She was successfully managed by medical treatment. The second patient, a 65 year-old male, presented with general weakness, nausea, vomiting and polyuria for 2 months. Combined pituitary stimulation test showed subnormal response of GH and prolactine. Radiologic studies revealed pituitary stone which was managed with medical treatment of hormone replacement. We suggest that calcific changes in the pituitary adenoma might be common and occur to the extent of pituitary stone formation with the possible alteration of hormonal secretion.
