AbstractAbstract PDF
Osteoporosis is a common clinical problem with high risk of fractures in old age, especially postmenopausal women.Secondary causes of osteoporosis can be identified in 20% of women and 40% of men with vertebral fractures. One of the causes of secondary osteoporosis is endocrine disease such as hypogonadism, ovarian agenesis, hyperadrenocorticism, hyperthyroidism, hyperparathyroidism and diabetes mellitus. Patients with Sheehan's syndrome have deficiency of multiple hormones which may cause bone loss.To determine changes in the bone mineral density in women with Sheehan's syndrome and to compare clinical and biochemical characteristics between the patients with osteoporosis and the patients without osteoporosis, we measured the bone mineral density(BMD) of the lumber spine and midradius by dual energy X-ray absortiometry(DEXA) and the serum levels of estrogen and osteocalcin in 11 patients of Sheehan's syndrome.The results were as follows;1) The BMDs of the lumbar spine were significantly decreased in patients with Sheehan's syndrome when compared with those of age-matched control.2) The prevalence of osteoporosis in patients with Sheehan's syndromes was 55%. Between the patients with osteoporosis and the patients without osteoporosis, there were no difference in the onset age of amenorrhea, the duration of amenorrhea, and the serum levels of osteocalcin and alkaline phosphatase.3) Serum estradiol levels were decreased uniformly in the patients with Sheehan's syndrome except three patients with estrogen replacement, but the concentration of estradiol was not correlated with the degree of the decrease in bone mass.In conclusion, the patients with Sheehan's syndrome have an increased prevalence of osteoporosis. But the effect of each anterior pituitary hormone deficiency on bone loss should be clarified in the futher prospective study.

AbstractAbstract PDF
The purpose of the present study was to define the normal range of plasma concentration of angiotensin I-converting enzyme(ACE), N-acetyl-b-D-glucosaminidase(NAG), inactive and active renin, and atrial natriuretic peptide(ANP) in normal Korean adult male in terms of aging. Both plasma ACE activity and NAG concentration were measured by spectrofluorometry, and the plasma renin activity and ANP concentration were measured using radioimmunoassay. The ACE was 67.7+-3.6 nM His-Leu/min/ml and did not change in terms of age. The plasma NAG activity tended to decrease. Both plasma active and inactive renin activities were 2.1+-0.2 and 3.0+-0.3 ngAI/ml/h and tended to decrease in terms of aging. The percentage of inactive renin to total renin was 57.2+-2.9% at age 21-30 and also tended to decrease in terms of aging. Plasma ANP concentration at age 22 was 59.6+-2.9 pg/ml.

AbstractAbstract PDF
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.

AbstractAbstract PDF
Lipomas are among the most common of all benign neoplasma and occur more frequently over the back, between the shoulders, and on the back of the neck. They are usually subcutaneous in origin, and characteristically multilobulated masses of fatty tissue that vary from small nodules to large masses weighing several kilograms.A mass in the anterior part of the neck may be initially thought to be thyroid nodules and then other cervical masses should be considered. Ultrasonographic examination of benign lipoma demonstrates solid and echogenic mass and may differentiate nonthyroid from thyroid masses. When lipoma is clinically suspected, the use of CTs can establish the correct diagnosis without the use of thyroid hormone suppression or the need for urgent surgery.We experienced a case of anterior cervical mass in a 51-year-old male patient presenting a non-tender and soft mass rapidly growing for recent several months and moved with swollowing, and diagnosed his case as benign lipoma using ultrasonography, computed tomographic scan, and fine niddle asperation biopsy and therefore when we encounter patients with anterior neck mass, we should consider benign lipoma mimicking thyroid nodule.

AbstractAbstract PDF
Recently it is known that Turner's syndrome is frequently associated with hypothyroidism. We report a case of Turner's syndrome associated with subclinical hypothyroidism. A 23-year-old female was admitted to the hospital with complaints of amenorrhea and short stature. She had a mosaicism of 45, X0/46, Xi(X_q) in the cell, cultured from the peripheral blood. The plasma thyroxine and triiodothyronine were normal and there was no clinical symptom of hypothyroidism. But the thyroid-stimulating hormone(TSH) concentration was unusually higher(184 uU/L). She has been treated with the cyclic therapy of conjugated estrogen and medroxyprogesterone, in addition to the thyroxine replacement therapy. After 2 months, the menstruation was restored and TSH was normalized.

AbstractAbstract PDF
We experienced a case of aldosterone and cortisol secreting adrenal adenoma associated with pregnancy in a 23 year old female patient.The patient complained of severe thoraco-lumbar pain, weight gain, sweating, anxiety, and mild abdominal discomfort. On physical findings, hypertension, tachycardia, facial plethora, moon face, buffalo hump and truncal obesity were found.

AbstractAbstract PDF
Klinefelter syndrome is the most common form of male hypogonadism. It is characterized by small, firm testis, gynecomastia, a variable degree of eunuchoidism, azoospermia, elevated gonadotropin level. Increased frequency of diabetes mellitus, breast cancer, empysema, chronic bronchitis, varicose vein, germ cell neoplasia occurs in Klinefelter syndrome. We report a 19 year-old male patient with diabetes mellitus in association with Klinefelter syndrome, which was confirmed by chromosome analysis. The patient is being treated with insulin for diabetes mellius and with testostrone replacement for Klinefelter syndrome.

AbstractAbstract PDF
The case is presented a 49-year-old man had several year history with chronic renal failure with hyperlipidemia due to diabetes mellitus. Treatment of hyperlipidemia was started by oral bezafibrate intake 600 mg per day. Several days later, patient noticed muscle weakness and myalgia. The serum CK, LDH, AST levels were remarkably elevated, myoglobulinuria was also noticed The symptoms of the patient were resolved after the drug was discontinued, thus the diagnosis was established as having bezafibrate induced rhabdomyolysis. On the basis of the above description, bezafibrate may induce muscle damage if dose is excess over the renal capacity. Extreme caution is warranted when the patient is placed on bezafibrate and has renal dysfunction.Strict dose adjustment is necessary in taking account of renal function to avoid muscle damage including rhabdomyolysis.

AbstractAbstract PDF
It is reported that patients with primary hyperparathyroidism(PHPT) have disturbances in carbohydrate metabolism: in particular, hyperinsulinemia and insulin resistance are characteristic early metabolic aberrations of this disease. However, it is not clear whether changes of insulin secretion or insulin sensitivity are observed in all patients with PHPT, including those with normal glucose tolerance. Also, it is not clear whether these changes are reversible after surgical correction of PHPT. In the present study, glucose tolerance and insulin secretion were evaluated in 2 symptomatic patients with PHPT during 100g oral glucose tolerance test before and after parathyroid adenoma removal. Comparing these patients before and after surgery, glucose tolerance was not significantly different. However, C-peptide and insulin secretion was low after surgical correction of PHPT compared to the preoperative situation. This observation suggests that insulin hypersecretion in patients with PHPT precedes glucose intolerance and this early disturbance is reversible after surgery.
