- BACKGROUND
Positive correlations between bone mass and androgen levels have been observed in premenopausal and postmenopausal women as well as in men. Androgen production was decreased in women with osteoporosis compared to that in age-matched controls. We hypothesized that androgen metabolism might be also deranged in osteoporosis. To clarify our hypothesis, we investigated the relationship between urinary metabolites of androgen and bone mineral density (BMD) in Korean postmenopausal osteoporotics. METHODS: We examined the anthropometry and bone turnover marker in 67 postmenopausal women. BMD was measured by dual energy X-ray absorptiometry (DEXA). Serurn levels of estrone, estradiol, free testosterone were measured by radioirnmunoassay and serum level of sex hormone binding globulin (SHBG) was measured by two site immunoradiometric assay. The urinary metabolites of androgen were determined by gas chromatography-mass spectrometry (GC-MS) at Korean Institute of Science and Technology Doping Control Center. RESULTS: 1. Spinal BMD had a positive correlation with height (r 0.3049, p<0.05), weight (r=0.4114, p<0.001) and body mass index (BMI, r=0.2638, p<0,05). 2. Spinal and femoral neck BMD had no correlation with serum levels of estrone, estradiol and ten major urinary metabolites of androgen, but serum free testosterone had positive correlation with spinal BMD (r=0.3622, p<0.01) and SHBG had negative correlation with femoral neck BMD (r=-0.2625, p< (0.05). 3. Serum free testosterone in osteoporotics was lower than non-osteoporotics with spinal BMD (p<0.05) and SHBG in patients with osteopenia was higher than non-osteopenic subjects with femoral neck BMD (p <0.05). 4. In multiple stepwise regression analysis, weight and serum free testosterone were statistically significant for spinal BMD (R =0.3072). As for femoral neck BMD, weight was the independent determinant (R 0.1307). 5. Serum level of osteo#ealcin and urinary deoxypyridinoline/creatinine had a positive correlation with urinary 11-ketoandrosterone (p<0.05). SHBG was positive correlation with osteocalcin (r=0.3190, p<0.05). 6. Serum free testosterone (r=-0.2740, p<0.05) decreased with aging. CONCLUSION: Our data suggest that androgen metabolism is not deranged in osteoporotics, but serum free testosterone is important than estrogen on postmenopausal osteoporosis after 5-10 years menopause.

- BACKGROUND
Hyperprolactinemia has been linked with hyperandrogenism and hirsutism in some women. High plasma Dihydroandrosterone and DHA-S levels were reported in patients with hyperprolactinemia and a dissociation of adrenal androgen and cortisol secretion occurs in normal subjects. The mechanism has not been elucidated, but it has been suggested that pituitary factors other than ACTH modulate adrenal androgen synthesis, One candidate hormone is prolactin. Adrenal tissue has been found to possess prolactin receptors and prolactin has been shown to act synergistically with ACTH and lowers the activity of the enzyme 5a-reductase or 3B-hydroxysteroid dehydrogenase (3B-HSD). The aim of this study was to investigate the secretion of adrenal androgen metabolites in patients with idiopathic hyperprolactinemia and prolactinoma and to deterrnine the relationship with prolactin and androgens. METHODS: We measured 24 hour-urinary DHEA, androstenedione, androsterone, pregnenolone, tetrahydrocorticoid and cortisol in 16 normal controls and 5 patients with idiopathic hyperprolac-tinemia (HP) and 12 patients with prolactonoma in the early follicular phase. RESULTS: Urinary DHEA, AD (androsteredione), and androsterone, the metabolites of adrenal androgen, were significantly higher in both patients with idiopathic HP and prolactinoma compared with those in normal controls (p<0.05), whereas they were not different in both disease groups. Urinary pregnenolone levels, early metabolite of adrenal steroid synthesis, were lower in patients. In contrast, urinary tetrahydorcortisol and cortisol were higher in patients compared to controls. There was no difference in DHEA:androsterone ratio between patients and controls. And there were no correlation between prolactin levels and the levels of androgenic metabolites or clinical symptoms. CONCLUSION: Prolactin has a tropic effct on the secretion of androgens and steroids by the adrenal cortex. But prolactin levels were not correlated with androgen levels or clinical symptoms (amenorrhea), and it might have little effect on lowering the activity of 3B-HSD.

- BACKGROUND
Primary empty sella syndrome (PES) is thought to arise from an incompetent diaphragma allowing progressive herniation of arachnoid membrane with secondary compression and atrophy of the pituitary gland. As a consequence of the improvement and widespread use of neuroradiological techniques, such as computerized tomography (CT) and magnetic resonance imaging (MRI), empty sella is more frequently disclosed. The aim of this study is to assess the associated clinical characteristics and endocrinologic disturbance in empty sella syndrome. METHODS: From January 1986 to June 1996, 171 patients with empty sella syndrome have undergone analysis for clinical characteristics and associated disease. RESULT: In our study, PES was diagnosed in 131 of the 171 patients (77%). Primary empty sella syndrome was frequent in middle aged women (female:male 115:16, mean age: 50.6+12.6 years). The common clinical features were headache (80.2%), obesity (72.5%), and hypertension (27.5%). Most of patients with PES have normal pituitary function (75%). The frequent pituitary dysfunction was hyperprolactinemia in PES (21%). Partial and total emptiness of sella on sella CT or MRI were in 111 (84.7%) patients, and in 20 (15.4%) patients, respectively. The most common associated disease with empty sella syndrome was pituitary adenoma. CONCLUSION: PES should be considered as a possible cause in obese middle aged women with unexplained headache. The combined pituitary function test should be considered for evaluation of pituitary dysfunction when clinically suspected.

- BACKGROUND
S: Pituitary hyperplasia can mimic pituitary adenoma. In MRI, enlarged pituitary gland is enhanced homogenously with upward convexity of the superior margin of the gland .The best definition of hyperplasia in the pituitary hyperplasia seems to be a multiplication of one or more cell types. But definition, etiology and clinical courses of this disease are not clear, METHOD: We reviewed clinical symptoms, MRI, and pathologic findindings in 6 patients with pituitary hyperplasia. RESULT: 1. Major clinical symptoms were headache (100%), visual field defect (84%), polyuria/polydipsia (64%), and irregular mensturation (32%). Other symptoms were amenorrhea (16%) and galactorrhea (16%). 2. Three of five cases showed abnormal responses to combined pituitary function test, 3. MRI findings were pituitary hyperplasia (4), macroadenoma (l), and microadenoma (1). 4. In two operated cases, there was no adenoma. One case showed hyperplasia of lactotroph cells, the other was hyperplasia of gonadotroph cells confirmed by the examination of immunocytochemistry. CONCLUSION: Pituitary hyperplasia should be considered in patients with enlarged pituitary gland without focal mass lesion.

Abstract
PDF
- Hashimotos thyroiditis and Graves disease have been thought to be the autoirnmune diseases having their distinct and separate clinical and pathologic features. Because of the partial and complete simi1arity in histologic feature, it has been hypothesized that Hashimoto's thyroiditis and Oraves disease may be interrelated. Several patients who had been diagnosed as Graves disease showed features of hypothyroidism, and were proven to have histologie features of Hashimotos thyroiditis in their thyroid tissue. Two meehanisms had been suggested to explain tbis phenomenon. One is that the combined Hashimotos thyroiditis in Graves' disease may become predominant with time, The other is that the amount of TSH receptor blocking antibody may increase in the course of Graves disease. Early recognition of these patients would be impartant to estabilish therapeutic plan. Futhermcee, extensive study of these patients would give more understanding of the mechanism of these diseases. Here we report 5 cases of clinically diagnosed Graves disease with pathologic features of Hashimotos thyroiditis or focal lymphocytic thyroiditis.
