AbstractAbstract PDF
A focal radioactive iodine uptake in the pelvis of a patient with differentiated thyroid cancer needs differential diagnosis besides bone metastasis. Struma ovarii is a rare monodermal ovarian teratoma composed predominantly of mature thyroid tissue; 5-10% of these tumors are malignant. As diagnosis and surgery of thyroid cancer have increased recently, incidental cases of struma ovarii, after radioactive iodine treatment, were occasionally reported. Rare cases of ovary metastasis of thyroid cancer were also reported. We report a case of benign struma ovarii incidentally found in a patient with papillary thyroid cancer. The patient showed a sustained high level of thyroglobulin and focal radioactive iodine uptake in the right pelvis, confused with distant metastasis, after total thyroidectomy and radioactive iodine treatment.

AbstractAbstract PDF
Non-islet cell tumor induced hypoglycemia (NICTH) is attributable to overproduction of insulin-like growth factor-II (IGF-II) by solid tumors, and these tumors usually originate from mesenchymal or epithelial cells. Gastrointestinal stromal tumor (GIST) is a rare mesenchymal tumor and most commonly find in the gastrointestinal tract. It is usually expresses the CD117 (stem cell factor receptor, c-kit) detected by immunohistochemistry. Hypoglycemia associated with GIST is very rare and this has not yet been reported in Korea. A 72-year-old man was hospitalized due to frequent episodes of confusion. It was observed that non-hyperinsulinemic hypoglycemia, an elevated serum IGF-II level and a huge liver mass. The histology of liver mass showed c-kit (CD117) positivity, which was consistent with GIST, but it was surgically unresectable. He was treated with imatinib mesylate. Although he recieved palliative treatment, he still experienced intermittent fasting hypoglycemia. After 2 months, the serum IGF-II level was even higher than before. We changed imatinib mesylate to sunitinib malate and performed radiotherapy on the liver mass. Although the change of the liver mass was not significant, he did not suffer from hypoglycemia for three months afterwards.

AbstractAbstract PDF
BACKGROUND
Primary aldosteronism is the most common cause of secondary hypertension in humans. Its prevalence is estimated to be 10-15% among hypertensive patients. It is also associated with insulin resistance and diabetes mellitus. The aim of our study was to compare the prevalence of primary aldosteronism in hypertensive patients with presence of diabetes mellitus. METHODS: We reviewed retrospectively the clinical records of 104 hypertensive patients for whom we also measured plasma renin activity (PRA) and plasma aldosterone concentrations (PAC). RESULTS: Among 104 hypertensive patients, 44 had diabetes and 60 did not. There were no significant differences in clinical characteristics between non-diabetic and diabetic patients except for age and the number of antihypertensive agents. Patients with target organ damage were more common among diabetic patients. There was no correlation between PAC and the number of target organs damaged. In addition, Four patients from the non-diabetic and two from the diabetic group had a ratio over 30 for PRA/PAC and a PAC of over 15 ng/dL. Two non-diabetic patients and one diabetic patient were found, on abdomen CT, to have an adrenal adenoma. The rest of the patients refused further tests. CONCLUSION: The prevalence of primary aldosteronism in diabetic patients does not differ significantly from that in non-diabetic patients. Therefore, the present routine screening test for primary aldosteronism in hypertensive diabetic patients is not recommended.

AbstractAbstract PDF
BACKGROUND
The objectives of our study were to assess the effects of oxidative stress on the proliferation, differentiation and apoptosis of human bone marrow stromal cell (BMSC)-derived osteoblasts and to explore pathways by which osteoblast cell apoptosis was induced. METHODS: Mononuclear cells including BMSCs were cultured to osteoblastic lineage. Different doses of hydrogen peroxide (H2O2) were added to the culture media. The colony forming units-fibroblastic (CFU-Fs) were stained with crystal violet and alkaline phosphatase (ALP). The MTT assay was done to see the effect of H2O2 on cell viability. The effect of H2O2 on osteocalcin gene expression was determined by RT-PCR. The matrix calcification measurement was performed. FACS analysis was performed to determine the osteoblasts apoptosis. Caspase-3, -8 and 9 activity assay and cytochrome c release were measured. RESULTS: The size and number of ALP (+) CFU-Fs were also decreased by H2O2 treatment. When compared with the control group, H2O2 significantly decreased the total number of cells of each culture well during MTT assay. H2O2 significantly diminished expression of osteocalcin mRNA. N-acetylcystein (NAC) blocked the diminution of cell viability and the inhibition of osteocalcin mRNA expression by H2O2. H2O2 reduced matrix calcification. FACS analysis revealed H2O2 increased percentage of apoptotic cells. Addition of H2O2 resulted in the increase of caspase-9 and -3 activity but not caspase-8, and release of cytochrome c to the cytosol. CONCLUSION: These data suggest that, in primary human BMSCs, oxidative stress inhibits proliferation of stromal cells and inhibits the differentiation to osteoblastic lineage. In addition, oxidative stress induces apoptosis of human BMSC-derived osteoblasts and this may be mediated by mitochondrial pathway of apoptotic signal.

AbstractAbstract PDF
Acromegaly is associated with an increased risk for a variety of cancers such as colon cancer, prostate cancer and breast cancer. However, there have been few reports of gastric cancer developing in an acromegaly patient. A 66-year-old man suffered with diabetes mellitus and hypertension for 15 years, and he visited the endocrinology department due to dizziness. On physical examination, the biochemical studies and the sella MRI, he showed the typical features of acromegaly with pituitary microadenoma. During the cancer screening studies to find the cause of anemia, early gastric cancer was diagnosed by pathologic examination of the tissue biopsies. We described the summary of characteristics of the patient and reviewed literature.

AbstractAbstract PDF
McCune-Albright syndrome (MAS) is a sporadic disease that's characterized by polyostotic fibrous dysplasia, cafe-au-lait pigmentation of the skin, and multiple endocrinopathies, including sexual precocity, hyperthyroidism, acromegaly, and hypercortisolism. Recent evidence has shown that the clinical manifestations are caused by a postzygotic activating missense mutation in the gene coding for the alpha-subunit of Gs protein that stimulates c-AMP formation in the affected tissues. Substitution of the Arg(201) residue in Gsalpha with cysteine or histidine have been identified in many MAS patients and Arg(201) to Gly or Leu mutations have also been recently identified. We identified the Arg(201) to His mutation in the gene encoding Gsalpha in the thyroid tissue from a 36-year-old man who was suffering with polyostotic fibrous dysplasia and hyperthyroidism.

AbstractAbstract PDF
BACKGROUND
The loss of bone mass is usually detected after bone marrow transplantation(BMT), particularly during the early post-transplant period. We recently reported that enhanced bone resorption following BMT was related to both the steroid dose and increase in IL-6. It was also suggested damage of the marrow microenvironment due to myeloablation and changes in bone growth factors contribute to post-BMT bone loss. Recently, the interactions of OPG and RANKL have been reported to be crucial in osteoclastogenesis and therefore in bone homeostasis. There are few data on the changes in RANKL/OPG status during the post-BMT period. This study investigated the changes in the levels of RANKL and OPG during the post-BMT period, and also assessed whether the changes in these cytokine levels actually influenced bone turnover and post-BMT bone loss. METHODS: We prospectively investigated 110 patients undergoing allogenic BMT and analyzed 36 (32.4+/-1.3 years, 17 men and 19 women) where DEXA was performed before and 1 year after the BMT. The serum bone turnover marker levels were measured before and 1, 2, 3, 4 and 12 wks, 6 Ms, and 1 yr after the BMT. The serum sRANKL and OPG levels were measured in all patients before and 1, 3 and 12 wks after the BMT. RESULTS: The mean bone losses in the lumbar spine and total proximal femur, which were calculated as the percent change from the baseline to 1 yr, were 5.2(P<0.01) and 11.6%(P<0.01), respectively. The mean serum ICTP, a bone resorption marker, increased progressively until 3 and 6 months after the BMT, but decreased gradually thereafter, reaching the basal values after 1 year. The serum osteocalcin levels decreased progressively until 3 wks after the BMT, then increased transiently at 3 and 6 Ms, but returned to the basal level by 1 yr. The serum sRANKL and OPG levels had increased significantly by weeks 1 and 3 compared with the baseline(P<0.01), but decreased at 3 months. The sRANKL/OPG ratio increased progressively until 3 weeks, but then decreased to the basal values. During the observation period, the percent changes from the baseline in the serum RANKL levels and RANKL/OPG ratio showed positive correlations with the percent changes from the baseline serum ICTP levels. Patients with higher RANKL levels and RANKL/OPG ratio during the early post-BMT period lost more bone mass at the lumbar spine. CONCLUSION: In conclusion, dynamic changes in the sRANKL and OPG levels were observed during the immediate post-BMT period, which were related to a decrease in bone formation and loss of L-spine BMD during the year following the BMT. Taken together, these results suggest that increased sRANKL levels and sRANKL/OPG ratios could be involved in a negative balance in bone metabolism following BMT.

AbstractAbstract PDF
Thyrotoxicosis associated atrial fibrillation occurs in 9 to 22% of hyperthyroidism patients; its prevalence increases after the age 60 years. Atrial fibrillation is known to be major independent risk factor for a thromboembolic stroke. The characterization of patient subgroups with atrial fibrillation, with high or low rate risk factor of a stroke, would help clinicians decide the benefit or harm to patient of long term anticoagulation therapy. Thyrotoxicosis, old age, hypertension, diabetes, heart failure, history of stroke and thromboembolism are all high risk factors for a stroke in atrial fibrillation patients. Thus, anticoagulation therapy is recommended for stroke prevention in those groups with atrial fibrillation and thyrotoxicosis. Herein is reported a case of acute cerebral infarction, with thyrotoxic atrial fibrillation and congestive heart failure, in a young woman

AbstractAbstract PDF
BACKGROUND
A loss of bone mass is usually detected after a bone marrow transplantation (BMT), especially during the early post-transplant period. We recently reported that enhanced bone resorption following a BMT was related to both the steroid dose and the increase in IL-6. We also suggested damage to the marrow stromal microenvironment, by myoablation, partly explains the impaired bone formation following a BMT. It is well known that some growth factors play important role in bone growth and osteogenesis. However, the pathogenetic role of bone growth factors in post-BMT bone loss is unknown and data on the changes in the growth factors, in accordance with bone turnover markers and bone mineral density (BMD) changes are scarce. We investigated changes in bone growth factors such as IGF-I (Insulin-like growth factor-I), fibroblast growth factor-2 (FGF-2) and Macrophage colony stimulating factor (M-CSF), during the post-BMT period, and assessed whether the growth factor changes influenced the bone turnover and post-BMT bone loss. The present study is the first prospective study to describe the changes in bone growth factors following a BMT. METHODS: We prospectively investigated 110 patients undergoing a BMT, and analyzed 36 patients (32.4+/-1.3 years, 17 men and 19 women) whose BMDs were measured before, and 1 year after, the BMT. The serum biochemical markers of bone turnover were measured before, 1, 2, 3 and 4 weeks, 3 and 6 months, and 1 year, after the BMT. The serum FGF-2, IGF-I and M-CSF levels were measured before and 1 and 3 weeks, and 3 months after the BMT. The correlation between the changes of growth factors and various bone parameters was analyzed. RESULTS: The mean bone losses in the lumbar spine and total proximal femur, calculated as the percentage change from the baseline to the level at 1 year, were 5.2 (p<0.05) and 11.6% (p<0.01), respectively. The serum type I carboxyterminal telopeptide (ICTP), a bone resorption marker, increased progressively until 6 months after the BMT, but thereafter decreased, to the base value after 1 year. Serum osteocalcin, a bone formation marker, decreased progressively, until 3 weeks after the BMT but then increased transiently, and finally returned to the base level at 1 year. The serum IGF-I and FGF-2 also decreased progressively until 3 weeks and 1 week after the BMT, respectively, then increased to the base values at 3 months. The serum M-CSF increased briskly at 1 week post-BMT, then decreased to the base level. There were positive correlations between the percentage changes from the baseline proximal femur BMD and the IGF-I levels 3 weeks and 3 months (r=0.52, p<0.01, r=0.41, p<0.05) post BMT. A Significant correlation was found between the IGF-I and osteocalcin levels pre-BMT, and 3 weeks after the BMT. Another positive correlation was found between the M-CSF and the ICTP levels at 3 weeks post BMT (r=0.54, p<0.05). CONCLUSION: In conclusion, there were significant changes in the serum IGF-I, FGF-2 and M-CSF levels in the immediate post-BMT period, which were related to a decrease in bone formation and loss in the proximal femoral BMD during the year following the BMT

AbstractAbstract PDF
BACKGROUND
It is crucial, in the case of regenerating bone by tissue-engineering technique, that osteoblast progenitors are proliferated and induced to differentiate to osteoblasts sequentially at the proper time. Osteoblasts can be obtained from bone itself or from osteoblast progenitors in bone marrow, even though the amount of human marrow stromal cells in marrow aspirate is usually scanty. These cells, however, have been known demonstrate the potential to easily proliferate and differentiate in osteoblasts, chondroblasts or adipocytes according to different microenvironmental factors. We evaluated the effect of dexamethasone and 1,25(OH)2D3 on the proliferation, differentiation, and mineralization of human marrow stromal cells in vitro. METHODS: We used twelve bone marrow aspirates obtained from different healthy bone marrow donors. Culture plates were randomly divided into the following four experimental groups; group 1 was cultured with control medium only, group 2 with control medium containing 1,25(OH)2D3, group 3 with control medium containing dexamethasone, and group 4 with control medium containing both 1,25(OH)2D3 and dexamethasone. 3H-thymidine uptake, protein content of cell lysates, alkaline phosphatase activities and alkaline phosphatase histochemistries were measured. Alizarin Red-S staining and quantification of dissolved dye were also performed. RESULTS: Combined stimulation of marrow stromal cells with both 1,25(OH)2D3 and dexamethasone was found to be effective to maintain stable long-term culture of the cells and to increased differentiation and mineralization of the cells. Synthesis and mineralization of matrix were highest when the cells were stimulated with 1,25(OH)2D3 alone during the early culture phase. However, 1,25(OH)2D3 shortened the lifespan of the cells. Interestingly, mineralization was higher in female donor cells than in male donor cells when stimulated with dexamethasone alone or with both dexamethasone and 1,25(OH)2D3. Neither 1,25(OH)2D3 nor dexamethasone affected cell proliferation. CONCLUSION: Our results suggest that the synergistic effect of dexamethasone and 1,25(OH)2D3 is important in maintaining long-term culture and differentiation of human marrow stromal cells. It is preferable to administer 1,25(OH)2D3 after the attachment of cultured osteoblasts to biomaterials has been established, since it could shorten cell survival despite the great increase of mineralization at the early culture phase.

BACKGROUND
Osteopenia or osteoporosis is one of the most frequently encountered complications in patients receiving various immunosuppressants after kidney transplantation. The few available preventive strategies for these complications tend to result in various outcomes. In this study, we evaluated the effect of intermittent etidronate therapy for the prevention of bone loss after kidney transplantation. METHODS: Fifty patients who received kidney transplantation for various reasons were recruited and followed for one year. Thirty-eight of these patients commenced etidronate treatment 7 days after operation, the other 12 were followed without etidronate therapy. The treatment consisted of 400mg of etidronate administered orally for 14 days, then repeated four-times every three months. Blood chemistry, iPTH and aluminium levels were tested periodically in all patients. Also checked were bone mineral density of the lumbar spine(L2-4) and femur at baseline, 6 and 12 months after kidney transplantation, as well as D-L spine lateral x-ray at baseline and 12 months. Serum osteocalcin and urine deoxypyridinoline were measured at baseline, 7 days and then every 3 months. RESULTS: Both the etidronate-treated and control groups showed significant decreases in bone mineral densities of the lumbar spine, femur neck and total femur at 6 and 12 months after kidney transplantation(p<0.005). Bone loss was significantly lower in the etidronate-treated group than the control at 12 months after kidney transplantation; lumbar spine(-3.54% vs. -9.51%, p<0.0005), femur neck (-5.41% vs. -8.91%, p<0.0005), total femur (-7.59% vs. -9.07%, p<0.005). Osteocalcin was decreased and deoxypyridinoline increased in both groups. No significant differences in the level or pattern of osteocalcin and deoxypyridinoline were observed in either group. New radiologic compression fractures were found in two patients of the treated group who exhibited severe osteoporosis at baseline during follow-up. CONCLUSIONS: The intermittent administration of etidronate seems to be effective in preventing rapid bone loss after kidney transplantation. Furthermore, this method is safe and convenient for administration and follow-up. Further studies will be required to elucidate the most effective treatment course for the prevention of fractures after kidney transplantation, especially in patients with established severe osteoporosis.

AbstractAbstract PDF
Fine-needle aspiration can be successfully utilized in the preoperative localization of abnormal parathyroid tissue. Fine-needle aspirate immunostaining for parathyroid hormone (PTH) or chromogranin and thyroglobulin (Tg) with measurement of PTH and Tg levels in the needle washings (FNAB-PTH and FNAB-Tg) can differentiate an enlarged parathyroid tissue from other cervical masses, such as thyroid nodules and lymph nodes. Parathyroid mass can be successfully aspirated by guidance of ultrasonography or computed tomography. Thyroid nodules are the most frequent cause of reduced accuracy of the imaging studies, such as ultrasonography, computer-assisted tomography and scintigraphy. We report on a case of unsuspected intrathyroidal parathyroid adenoma coexisted with thyroid follicular adenoma presenting two thyroid nodules. After biochemical diagnosis of hyperparathyroidism, we could not localize the parathyroid lesion specifically with any imaging method. Through fine-needle aspiration of two thyroid nodules, we performed the immunostaining for chromogranin and thyroglobulin and the measurement of PTH and thyroglobulin levels in the aspirated materials. The results confirmed the right nodule to be thyroid lesion and the left nodule to be parathyroid lesion preoperatively.

BACKGROUND
Bone marrow transplantation is the treatment of choice for patients with certain- hematological malignancies, many of whom will survive many years thereafter. Bone disease is a potential longterm complication. But, little is known about the effects of bone marrow transplantation on bone. METHODS: In this study, bone marrow was obtained from healthy donor and transplant recipients. Then mononuclear cells including marrow stromal cells were isolated and cultured. At near confluence, bone marrow stromal cells were subcultured. Thereafter alkaline phosphatase activities of each group were measured by time course of secondary culture. We also analysed the origin of marrow stromal cells by the polymerase chain reaction using YNZ 22 minisatellite probe. RESULTS: l. Cells cultured in our system showed the characteristics of marrow stromal cells differentiated to osteoblasts. They were in fibroblast-like spindle shape and positive to alkaline pbosphatase histochemistry and Von Kossa histochemistry in secondary cultures. 2. The time required for the near confluence in the primary culture was 15 days and 22.9 days on the average in healthy donors and transplant recipients, respectively (p=0.003). 3. In secondary cultures, healthy donors and transplant recipients showed peak alkaline phosphatase activity at 10 days and 17 days, respectively (p=0.031). Alkaline phosphatase activity was lower in BMT recipients than in healthy donors during the whole period of secondary cultures. 4. In polymerase chain reaction analysis using YNZ 22 minisatellite probe, bone marrow stromal cells were of recipient origin. CONCLUSION: Recipient-derived bone marrow stromal cells may be damaged secondary to the effect of chemotherapy, glucocorticoid & total body irradiation which have given before bone marrow transplantation. So it may affect the differentiation of bone marrow stromal cells into the osteoblasts.

AbstractAbstract PDF
BACKGROUND
Loss of bone mass is usually detected after BMT. The causes of bone loss are related with gonadal dysfunction and immunosuppressants. Cytokines, especially IL-6, play an important role in the pathogenesis of postmenopausal osteoporosis. However, the pathogenetic role of cytokines in post-BMT bone loss is unknown and data on the changes of cytokines in accordance with bone turnover markers are scarce. The aim of this study is to assess the relationship of bone turnover markers and cytokines of peripheral blood and bone marrow before and after allogeneic BMT. METHODS: This prospective study included two analyses. The first was a study of 46 BMT recipients, examining the relationship between bone turnover markers and cytokines of serum which were measured before and 1, 2, 3, 4 week and 3 months after BMT. The second was a study of 14 BMT patients, measuring bone marrow plasma cytokines such as IL-6 and TNF-alpha at post-BMT 3 week and bone turnover marker at the same time to assess the relationship between two parameters. RESULTS: Serum ICTP, bone resorption marker, increased progressively until 4 weeks (peak) after BMT and then decreased thereafter. Serum osteocalcin, bone formation marker, decreased progressively until 3 weeks after BMT and then increased thereafter. There was positive correlation between serum ICTP and bone marrow IL-6 levels at the post-BMT 3 week with a statistical significance, but the correlation between bone turnover markers and bone marrow TNF-alpha or peripheral blood cytokines was not found. CONCLUSION: Our data suggest that the progressive increase of bone resorption after BMT is related with the increase of bone marrow IL-6, which is a potent stimulator of bone resorption in vivo.

BACKGROUND
The organ transplantation becomes the management of choice for many patients with chronic and life threatening heart, liver, kidney, bone marrow, and pancreatic diseases. A new set of side effects unique to this groups of patients has become recognized. Bone disease is one of these complications. It is well known that there is an interplay between the cells in the bone marrow and the surrounding bone tissue. Marrow stromal cells include the progenitors of the osteoblastic lineage are the sources of effector molecules that support and regulate both hematopoiesis and bone remodeling. But little is known about the effects of myeloablative treatment followed by bone marrow transplantation(BMT) on bone metabolism. METHODS: We have investigated prospectively in 29 patients undergoing BMT(4 autologous, 25 allogenic) for hematologic diseases(19 leukemia, 9 severe aplastic anemia, 1 myelodyspoietic syndrome). Serum concentrations of calcium, phosphorus, creatinine, gonadotropins, sex hormones and biochemical markers of bone turnover(osteocalcin and carboxyterminal cross-linked telopeptide of type I collagen(ICTP)] were measured. The samples were collected before BMT and 1, 2, 3, 4, 12 weeks, 6 months and 1 year thereafter. Bone mineral density was measured with DEXA(Dual Energy X-ray Absorptiometry) before and after 1 year of BMT. RESULTS: 1. ICIP was progressively increased until 4 weeks after BMT when peak values were reached. And then decreased thereafter and basal values were regained after 1 year. Osteocalcin was progressively decreased until 3 weeks after BMT when nadir values were reached. And then increased thereafter and basal values were regained after 3 months. No distinct differences were observed in serum biochemical turnover marker between both sexes and between patients who received total body irradiation and those who did not. 2. Lumbar BMD was 2.1% decreased from 1.113 +/- 0.132 g/cm to 1.089 +/- 0.137 g/cm, and femoral BMD was 6.2% decreased fiom 1.078 +/- 0.156 g/cm to 1.011 +/- 0.157 g/cm. 3. 92% of the women (11/12) became menopausal manifested by high gonadotropin and low estradiol levels immediately after BMT. In contrast to women, gonadotropins and testosterone levels were not changed significantly in men after BMT. CONCLUSION: The rapid impairment of bone formation and also increase in bone resorption, as mirrored by the biochemical markers in this study, might play a role for the post-BMT bone loss. Further studies over many patients with a longer follow up will be needed.

AbstractAbstract PDF
Paraganglioma is an extraadrenal pheochromocytoma originating from chromaffin ceIls distributed in sympathetic nervous systems. This tumor often can produce catecholamines and induce sustained or paroxysmal hypertension, with or without the typical symptams of headache, palpitation and sweating. Paraganglioma without the usual clinical manifestations is not easy to suspect and diagnose. Herein, we report a case of atypical retroperitoneal paraganglioma which was thought to be the pancreas tail mass and result in a paroxysmal adrenergic crisis and fatal dilated cardiomyopathy after the sonographically guided percutaneous biopsy. This rare case warns against the usual practice of percutaneous biopsy for the preoperative diagnosis of intraabdominal or retmperitoneal tumors.
