- BACKGROUND
Obese postmenopausal women usually have a tend to have greater bone mineral density than lean women. This has been attributed to either the mechanical effects of their excessive weight on bone tissue or to their high body fat content. A recent study demonstrated that leptin, the hormone produced in adipocytes, acts on bone metabolism. These findings have prompted speculations on the possible role of leptin in the protective effect of obesity on bone. METHEODS: We studied the relationship between serum leptin levels and quantitative ultrasound (QUS) values of calcaneus in 94 postmenopausal Korean women who were randomly selected from the population of the Chung-Up osteoporosis prevalence study. QUS values, broadband ultrasound attenuation and speed of sound; were measured at the calcaneus. RESULTS: Leptin values were strongly correlated with body mass index (r = 0.478, p< 0.001), confirming a positive relationship between leptin levels and fat mass. In contrast, no significant correlations were observed between serum leptin levels and calcaneal QUS values. CONCLUSION: Our results suggest that circulating plasma leptin does not have a significant influence on QUS values of calcaneus in Korean postmenopausal women.

- BACKGROUND
Percutaneous ethanol injection therapy (PEI) performed with ultrasonography guidance has recently been used in cases of autonomous functioning thyroid nodules (AFTN) and benign complex cysts. We performed this study to analyze the effects of PEI on AFTN and benign complex cysts. METHEODS: From September 1995 to September 2000, we performed PEI on 456 outpatients (47 men and 409 women, mean age 42.4+/-11.8 years) with AFTN or benign complex cysts. All cases were subjected to fine needle aspirations (FNA) by ultrasonography-guidance if necessary. FNA was performed at least twice with results of colloid nodule in cases of complex cysts. For AFTN, cases with FNA results of follicular neoplasm were also included. After PEI on AFTN, patients were classified into three response groups: complete response as judged by our new criteria (CR, normalization of TSH and free T4, disappearance of hot nodule on thyroid scan) along with the old criteria of previous studies (normalization of TSH and free T4, recovery of suppressed extranodular tissue on thyroid scan), partial response (PR, normalized free T4 but suppressed TSH, persistent hot nodule despite recovery in suppressed extranodular tissue) and no response (no change of hot nodule). Complex cysts were classified into three groups in accordance with volume reduction after PEI: complete response (CR, above 90% of volume reduction), partial response (PR, 50~89%) and no response (below 50%). RESULTS: Overall pre-treatment volumes were 15.3+/-12.1 mL and post-treatment volumes were 2.8+/-2.9 mL, with 66.4+/-19.9% of volume reductions in AFTN and complex cysts. Volume reductions were 71.5+/-18.0% in AFTN, and 66.1+/-15.0% in complex cysts. In 24 cases of AFTN, responses satisfying the previous criteria were 14 (58.3%) of CR, 6 (25.0%) of PR, and 4 (16.7%) of no response. However, by the new criteria there were 1 (4.2%) of CR, 10 (41.6%) of PR, and 13 (54.2%) of no response. In 432 cases of complex cysts, CR was observed in 82 (19.0%), PR in 261 (60.4%) and no response in 89 (20.6%). The volume reductions in complex cysts with pre-treatment volume larger than 15 mL were higher than those of groups with smaller volumes (p<0.001). Pre-treatment volumes were not correlated with post-treatment volumes, nor with volume reductions. Volume reductions were not correlated with the amounts of injected ethanol. Mild and transient complications were observed in 41 cases (9.0%) during PEI, consisting of transient neck pain (n=36, 7.9%), transient unilateral vocal cord palsy (n=3, 0.7%), intracavitary hemorrhage (n=1, 0.2%), and transient hypotension (n=1, 0.2%). CONCLUSION: Our data suggest that the efficacy of PEI on AFTN is temporary and does not usually induce long-term complete remissions. In complex cysts, however, PEI may have potential as an additive treatment modality to thyroid hormone suppressive therapy

- BACKGROUND
Percutaneous ethanol injection therapy (PEI) which is performed with the guidance of ultrasonography has recently been used in patient who had benign cold thyroid nodules. We performed this study to analyze the long-term effects of PEI on benign cold thyroid nodules. METHOD: From September 1995 to September 2000, we treated 198 outpatients (12 men and 186 women, who had a mean age of 40.8 years, with a range of 15-71) who had benign cold thyroid nodules at the Asan Medical Center. The PEI was performed on 141 patients who had solitary nodules (SN) and on 57 patients who had prominent nodules or Questionable or typing error? multiple nodules (MN). All patients had fine needle aspirations (FNAs) at least twice which resulted in a diagnosis of the presence of a colloid nodule. Thyroid hormone was given to all patients along with TSH measurements. The thyroid hormone dose was titrated to correspond to TSH level of a low normal range. These patients were followed up for mean period of 37.6 months (range 18-60). Patients who were treated with PEI were classified into three groups according to their volume reduction: a complete response (CR, which was above 90% in volume reduction), a partial response (PR, which was a 50-89%) reduction and No Response (which was below 50% or an increased size) groups. RESULTS: The overall pre-treatment volumes of the nodules were 15.7+/-19.8 mL. The overall post-treatment volumes were 2.4+/-2.6 mL and consisted of volume reductions of 70.1+/-17.1%. The results of PEI for all of the patients were: a complete reduction (CR) in 34 cases (17.2%), a partial reduction (PR) in 142 cases (71.7%) and No Response in 22 patients (11.1%). In 141 patients in the SN group, in which there was a mean follow-up duration of 36.7+/-11.2 months, the volume reductions were 68.3+/-18.8%. CR was observed in 20 patients (14.2%), PR in 103 (73.0%) and No Response in 18 (12.8%). In twenty-two of the SN patients (22/141, 15.6%) we were able to discontinue the thyroid hormone suppressive therapy because those nodules had markedly decreased in volume after PEI without any further increase of nodule size during the follow-up period. In 57 patients in the MN group, over a mean follow-up durations of 37.1+/-11.4 months, the volume reductions were 74.3+/-12.1%. CR was observed in 14 patients (24.6%), PR in 39 (68.4%) and No Response occurred in 4 (7.0%). During the follow-up period after PEI, further volume reductions were observed for 36 months after thyroid hormone suppressive therapy in the Response Group. Differences in volume reductions between the SN and MN groups were not statistically significant but the volume reductions in patients who had a pre-treatment volume larger than 15 mL were higher than those in the smaller group (p<0.001). In the cases of the SN and MN groups, volume reductions did not correlate with either the amount of injected ethanol or the pre-treatment volumes, but the pre-treatment volumes correlated with post-treatment volumes in the patients who had SN (p<0.001, r=0.411) and MN (p<0.001, r=0.729). We observed mild, but transient complications in 32 patients (16.2%) during PEI which included a transient neck pain (n=27, 13.6%), a transient unilateral vocal cord palsy (n=4, 2.0%), and an abscess formation (n=1, 0.5%) which was cured. CONCLUSION: These results suggest that PEI is a feasible adjunctive therapy to use in thyroid hormone suppressive therapy for benign cold thyroid nodules

- BACKGROUND
Genetic suggest that strongest effect is observed in the premenopausal peak bone mass, which become less with age. However, the evaluation of candidate genes polymorphisms has been most frequently done in postmenopausal women and the results have been controversial. Therefore, we studied the possible association of the peak bone mass and candidate for osteoporosis genes polymorphism in premenopausal women. METHODS: The associations between BMD and polymorphisms of the vitamin D receptor (3'-end region by BsmI restriction enzyme and start codon by FokI restriction enzyme), estrogen receptor (by PvuII and XbaI restriction enzyme), and type I collagen 1 (Sp1 binding site by MscI and BalI restriction enzyme) genes were examined in 100 healthy young Korean women who had a peak bone mass (age 20-35 years). Bone mineral densities were measured by dual energy X-ray absorptiometry (DEXA). Dietary calcium intake was also measured using a food frequency questionnaire. RESULTS: The frequencies of the B allele of the vitamin D receptor gene BsmI polymorphism and the X allele in the estrogen receptor gene, XbaI polymorphisms were lower in Koreans than those in Caucasians. The allelic frequencies of the vitamin vitamin D receptor gene FokI polymorphism and the estrogen receptor gene PvuII polymorphism were similar to those of Caucasians. No significant association was found between BMD and the vitamin D receptor genotype according to BsmI or FokI polymorphisms. There was also no significant relation between the PvuII or XbaI polymorphisms of the estrogen receptor gene and BMD. The associations between BMD and cross-genotypes combining the vitamin D receptor gene (BsmI and FokI) and estrogen receptor gene (PvuII and XbaI) polymorphisms were also analyzed. Among the subjects who lacked the Bf haplotype of the vitamin D receptor gene, the BMD of the femoral neck area was significantly higher in subjects lacking Px haplotypes of the estrogen receptor gene than in those having Px haplotype (p < 0.05). When dietary calcium intake was taken into consideration, there were significant differences in BMD according to the cross-genotype in the group having a low calcium intake (< 500 mg/day). The subjects that lacked the Bf and Px haplotypes had a significantly higher BMD in the femoral neck (p < 0.01), Ward's triangle (p < 0.05), and in the trochanteric area (p < 0.05) than those who lacked Bf but a Px haplotype. We did not find a polymorphism in the Sp1 binding site of the type I collagen 1 gene in our subjects. CONCLUSION: These data suggest that a complex interaction of vitamin D and the estrogen receptor gene with the dietary calcium intake, rather than a polymorphism of a single gene, may influence peak bone mass in healthy young Korean women.

- BACKGROUND
Graves' ophthalmopathy (GO) is an autoimmune process that affects the orbital tissues. Patients with GO are usually treated with high doses of corticosteroids, retrobulbar irradiation, or by surgical decompression, however, those have some adverse effect. Recently, a synthetic somatostatin analogue has been reported for the treatment of GO. This study was performed prospectively to evaluate the therapeutic effects of lanreotide, a potent long acting synthetic somatostatin analogue, in patients that have GO. METHODS: Eight patients with moderate to severe GO (M:F=1:7, age 39.0+/-11.8 years) were included. Patients who had been treated with other modalities than GO, or had a systemic illness such as diabetes were excluded. Eight patients were given lanreotide, 40mg IM every 2 weeks over a period of 8 weeks. Their therapeutic responses were evaluated using an orbital CT or MRI and by ophthalmologic examinations. RESULTS: After 8 weeks' of lanreotide treatment, 4 patients showed decreased scores in the NOSPECS classification (p=0.059) as well as 5 patients in their clinical activity scores(p=0.109). All of the 8 patients showed improvements according to clinical evaluation criteria (p=0.008). Significant changes in the thickness of both the lateral rectus and superior rectus muscles were observed (p<0.05). No patient showed serious adverse effects related to lanreotide therapy during the follow-up periods. CONCLUSION: We conclude that lanreotide therapy has clinical benefits and show radiologic improvements in GO. Considering the minimal side-effects of lanreotide compared to those of corticosteroid, lanreotide therapy should be considered for use in selected patients that have Graves' ophthalmopathy

- BACKGROUND
Thyroglobulin (Tg) measurement is primarily used to monitor patients with well differentiated thyroid carcinomas (WDTC) for tumor recurrence. We evaluated the correlations between fold responses of thyroglobulin levels and TNM stages (and MACIS scores) at recurrent group. Also correlations between preoperative Tg levels and Tg (on or off replacement) levels at the time of recurrence were evaluated. Postoperative Tg levels between recurrent and non-recurrent groups were analyzed for the use of assessing risk of recurrence. METHODS: One hundred twenty five cases of WDTC who had total thyroidectomy and (131)I remnant thyroid ablation were finally included in this study. After optimal TSH stimulations (>30 microIU/mL), (131)I whole body scan (WBS) was performed. We interpreted as a recurrence only when abnormal findings on the (131)I WBS were detected. Preoperative, immediate postoperative and follow-up Tg tlevels were regularly measured. RESULTS: Difference of preoperative Tg levels between recurrent and non-recurrent groups was not significant (27.5+/-4.2 ng/mL vs. 16.0+/-10.9 ng/mL). Also differences of immediate postoperative Tg (on or off replacement) levels between two groups was not significant (2.4+/-3.8 ng/mL vs. 3.6+/-3.l ng/mL, 33.4+/-4.8 ng/ml vs. 24.5+/-4.8 ng/mL, respectively). Tg levels on replacement at 24 months after surgery between recurrent and non-recurrent groups were significantly different (2.2+/-4.8 ng/mL, 15.9+/-6.5 ng/mL, p<0.001) and also Tg levels off replacement between recurrent and non-recurrent groups were significantly different (4.0+/-6.6ng/mL vs. 49.4+/-9.3 ng/mL, p<0.001). Fold responses between recurrent and non-recurrent groups were significantly different (2.0+/-3.1 ng/mL, 5.0+/-4.1 ng/mL, p=0.009). Fold responses between recurrent and non- recurrent groups were significantly different according to TNM stages (p=0.002) but not different according to MACIS scores. Preoperative Tg levels were correlated Tg (on or off replacement) levels at the time of recurrence (p=0.02, r=0.4: p<0.001, r=0.6, respectively). Sensitivity, specificity, accuracy of Tg levels over 2 ng/mL on replacement were 95%, 73%, 84% but those of Tg levels over 7 ng/mL off replacement were 83%, 70%, 77%. CONCLUSION: Fold responses may predict prognosis of WDTC. Small postoperative increase in serum Tg levels may indicate a large increase of tumor mass in cases of normal or low preoperative Tg levels. Tg levels over 2 ng/mL on replacement or 7 ng/mL off replacement during follow-up may suggest the recurrence of WDTC.

- BACKGROUND
After total thyroidectomy the presence of detectable serum thyroglobulin(Tg) concentration is an index of residual or metastatic thyroid tissue and is usually well correlated with positive I whole body scan. However, it is not rare to find a patient with detectable serum Tg levels but without any uptake on I whole-body scan. At present it is not certain how to manage such patients. We performed whole body scan after administration of therapeutic dose of 131I to evaluate the usefulness of radioactive iodine therapy in the above setting. METHODS: Fifteen patients (4 males and 11 females, ranging in age from 17 to 74 years) were studied. They had been previously treated with total thyroidectomy for papillary thyroid cancer followed by therapy with 131I for ablation of their thyroid residue. Tg levels were determined by immunoradiometric assay method. 131I (100-200 mCi) therapy was administered and whole body scan was performed. 99mTc MIBI scans were taken in 9 patients. Follow up data of Tg were available in 12 patients at time interval of 6 12 months from the first study and treatment. RESULTS: Tg(on) levels of these patients were in a range of 2.2210 ng/mL (mean 36.1 +/- 59.1 ng/mL) and Tg(off) levels were 17.3 1,592 ng/mL (mean 197.3 +/- 400.3 ng/mL). After radioiodide therapy, Tg(on) levels were in 1.48.5 ng/mL (mean 11.0 +/- 13.5 ng/mL), Tg (off) were 11.9 478.0 ng/mL (mean 159.3 +/- 159.8 ng/mL). The Tg (on) levels were decreased significantly after RAI therapy, but Tg (off) levels had no significant difference, In 8 of the 15 patients (53.3%), posttreatment whole body scan showed definite positive uptakes which were not evident in pretreatment diagnostic scan. There were local recurrence in 3 cases, regional lymph node metastasis in 4 cases, and lung in I case. Diffuse hepatic uptake was definitely seen in 7 cases. The MIBI scan showed abnorml uptakes in 4 of 9 cases. CONCLUSION: The therapeutic usefulness of 100 to 200 mCi of 131I treatment in patients with 131I scan-negative and Tg-positive was unclear. And the MIBI scan was only partially effective. Further studies with other diagnostic and therapeutic approachs are required to evaluate the exact lesions and to improve prognosis.

- Thyroid-stimulating hormone (TSH) is the most sensitive marker reflecting thyroid function. TraditionaUy, TSH concentration was measured by the method of RadioImmunoAssay (RIA) with the detection limits around 1 to 2 mIU/L, which was unable to differentiate hyperthyroid status. Since 1980s, owing to the sensitive assay for TSH, immunoradiometric assay (IRMA), it has been possible to detect low concentration of TSH by 0.001 mlU/L. TSH is composed of two glycopeptide subunits, a-subunit and B-subunit. Monoclonal antibodies, directed against two different sites of the TSH peptides, are used in IRMA. One antibody is directed toward the specific B-subunit of TSH molecule and is used to extract it from serum, a second antibody labelled with a radioactive material is then attached to the separated TSH to form "sandwhich" molecule that can be measured. Generally, mouse monoclonal antibodies are used as capture and detection antibodies. Infrequently, when there is heterophilic antibody, i.e. human anti-mouse antibody (HAMA), TSH can be measured as spuriously elevated, since HAMA may form a link between the signal and capture molecules. We report a case of inappropriately elevated TSH concentration due to heterophilic antibody, later diagnosed as Graves disease. A 41-year-old woman visited our clinic with the chief complaints of hand tremor, hyperphagia, weight loss for 3 months. Two years earlier, she underwent total colectomy due to colon cancer and had treat on multiple chemotherapies. The results of thyroid function test shows that TSH was 0.77 mIU/L, free T was 7.1 ng/dL (0.8~1.9), free T was 11.3 pg/mL (0.2~5.5). Thyroid specific auto- antibody results were anti-Tg-Ab 21.3 m/mL(0 100), anti-TPO-Ab 87.9m/mL(0100), TBIAb 7.8% (-15/15). Thyroid scan showed that radioactiveiodine uptake was increased and thyroid gland wasenlarged diffusely. Because TSH level was elevated, further evaluations were performed to differentiate with TSH producing pituitary tumor and pituitary resistance to thyroid hormone. Sellar MRI was normal, TRH stimulation test showed flat response. Since spurious elevation of TSH is possible at the presence of hetrophilic antibody, we rechecked TSH concentration after adding mouse monoclonal antibody to the patients serum with result of TSH less than 0.05 mIU/L. She was able to be diagnosed as Graves disease, and started with methimazole. Three months later, thyroid function test showed that TSH was 10.5 mIU/L, free T4 was 1.0 ng/dL, free T3 was 4.0 pg/mL. TSH level after removal the effect of heterophilic antibody with mouse monoclonal antibody was 0.71 mIU/L. Neutropenia was developed 5 months after methimazole therapy, to stop antithyroid medication. With the plan of radioactive iodine therapy if she relapses, she is being followed with periodic thyroid function test. We report a case of Graves disease with spuriously elevated TSH due to the effect of heterophilic antibodies.

- MEN type 1 is characterized primarily by the presence of functioning and nonfunctioning tumors or hyperplasia of the pituitary gland, parathyroid glands, and pancreatic islet cells. Pancreatic islet tumors in MEN type 1 produce different kinds of hormone which were pancreatic polypeptide, gastrin, glucagon, insulin and so on. To date, ten cases had been reported in Korea. We report another case with MEN type 1 having prolatin-secreating pituitary adenoma, parathyroid hyperplasia and insulinoma. A 36-year-old woman was admitted because of long-standing amenorrhea and recently diagnosed osteoporosis. Otherwise, she had been in good health except experiencing one episode of loss of consciousness after skipped meal. The blood chemistries were normal except hypercalcemia and hypophosphatemia. Hormonal studies revealed elevated levels of intact PTH and prolactin and decreased value of estradiol with low LH and FSH. The neck CT revealed 1 cm-sized nodule at posterior portion of right thyroid gland and 99mTc-sestamibi sintigraphy showed a increased uptake in left lower and right lower parathyroid glands. The sella MRI showed 0.7 cm-sized enhanced lesion in the left pituitary gland. The ratio of immunoreactive insulin to glucose was elevated and 3-4 pancreatic masses of variable size were identified by endoscopic ultrasonography and angiography. Subtotal parathyroidectomy and pyrolus-preserving pancreaticoduodenectomy with spleen-preserving distal pancreatectomy was done. Postoperative she had been doing well with normocalcemia and normoglycemia. Transsphenoidal adenonectomy was done 5 months later. Histologic examination of removed tissues revealed a single insulinoma, prathyroid hyperplasia and prolactin-secreating pituitary adenoma.

- We report a case of somatostatinoma, which manifested as insulinoma after liver metastasis. A 74-year-old man suffered from diabetes mellitus and jaundice. The abdominal CT scan of this patient showed a mass in the pancreas head, which obstructed biliary duct. He underwent Whipples procedure. Immunohistochemical staining of postoperative specimen disclosed that this tumor was strongly positive for somatostatin. After 4 months, follow up CT scan showed multiple metastatic lesions in the liver. We performed transarterial chemoinfusion two times, but the response was disappointing. After 2 months, he suffered from altered mentality, which was relieved by intake of sugar. Biochemical laboratory findings and immunohistochemical staining of liver biopsy disclosed that the metastatic lesion in this patient was insulinoma. We performed embolization of hepatic artery with gelform. The biochemical response was dramatic, but he died of septic shock, which was caused by gas forming liver abscess. In summary, we report a case of somatostatinoma which manifested as insulinoma after metastasis to the liver.

- Chronic hypophosphatemia caused by decreased intestinal absorption or increased renal clearance, may lead to rickets or osteomalacia independently of other predisposing abnormalities. The conditions commonly associated with increased renal clearance of phosphate are X-linked hypophosphatemic rickets, tumor associated rickets/osteomalacia, RTA and Fanconi syndrome. Recently we experienced 3 men with adult-onset, histologically proven osteomalacia associated with increased renal clearance of phosphate. None of them had a family history of bone disease, tumors or other tubular defects. All of these had remarkable biochemical and clinical improvement with medical treatment such as 1, 25-dihydroxyvitamin D and phosphate supplementation. Although we did not find tumors yet, we could not rule out the possibility of tumor-associated osteomalcia since it often takes several years to make a diagnosis because of small size, benign nature and unusual location of tumors. Thus, careful long-term follow up for tumor occurrence will be maintained in these patients with sporadic nonfamilial hypophosphatemic osteomalacia.
