Abstract PDF: Although tubercrlosis is one of the recognized causes of adrenal insufficiency, little is known about adrenal function in patients with active pulmonary tuberculosis. Patients with active pulmonary tuberculosis are at risk from sudden and unexpected death which can occur during the first few weeks of treatment. There are many reports that patients who received rifampicin as a part of their treatment appeared to show impairment in adrenocortical function when compared to a group who received anti-tuberculosis chemotherapy which did not include rifampicin. Adrenocortical function was studied in 15 patients(7 males, 8 females) with active pulmonary tuberculosis, before and 2-weeks after the anti-tuberculosis chemotherapy including rifampicin. At 08: 00 hour a base-line sample of venous blood was taken. One hour after the administration of 0.25mg of Synacthen, a further blood specimen was taken. The base-line and 1-hour specimens were analysed for plasma cortisol and electrolytes.All were initially found to have a normal cortisol response to rapid ACTH stimulation test. Following a 2-week course of anti-tuberculosis chemotherapy including rifampicin there was 1 case(6.6%) of a suboptimal response.Rifampicin, a powerful anti-tuberculosis drug, is a known inducer of the hepatic microsomal enzyme system and has been shown to cause an enhanced clearance of endogenous cortisol. Findings reported in this paper suggest that the adrenocortical function is compromised in some case(6.6%) of tuberculosis patients. It will therefore be necessary to undertake detailed investigations on the effect of treatment with daily and fully intermittent regimens containing rifampicin on the function of this endocrine gland.

Abstract 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.

Abstract PDF PubReader

Gynecomastia is a benign enlargement of the male breast caused by the proliferation of glandular breast tissue. Determining the various causes of gynecomastia such as physiological causes, drugs, systemic diseases, and endocrine disorders is important. Androgen insensitivity syndrome (AIS) is a rare endocrine disorder presenting with gynecomastia and is a disorder of male sexual differentiation caused by mutations within the androgen receptor gene. All individuals with AIS have the 46 XY karyotype, although AIS phenotypes can be classified as mild, partial or complete and can differ among both males and females including ambiguous genitalia or infertility in males. We experienced a case of partial AIS presenting with gynecomastia and identified the androgen receptor gene mutation.

Abstract PDF PubReader

Acute suppurative thyroiditis (AST) is a rare condition, as the thyroid gland is relatively resistant to infection. Thyroid function tests are usually normal in AST. A few cases of AST associated with thyrotoxicosis have been reported in adults. We report a case of AST that was associated with thyrotoxicosis in a 70-year-old woman. We diagnosed AST with thyroid ultrasonography and fine needle aspiration of pus. The patient improved after surgical intervention and had no anatomical abnormality. Fine needle aspiration is the best method for the difficult task of differentiating malignancy and subacute thyroiditis from AST with thyrotoxicosis. Earlier diagnosis and proper treatment for AST might improve the outcome.

Abstract PDF: Pseudohypoparathyroidism is a rare disease that is characterized by target cell resistance to the effects of parathyroid hormone and this disease is classified into various types depending on the phenotypic and biochemical findings. The patients with pseudohypoparathyroidism present with the clinical and biochemical features of hypoparathyroidism, but they have an increased serum level of parathyroid hormone. We experienced a case of pseudohypoparathyroidism in a 24 years old woman who had Graves' disease at that time. She had hypocalcemia, hyperphosphatemia, an elevated serum parathyroid hormone level and a normal urinary basal cyclic AMP(adenosine monophosphate) level. She also had a normal phenotypic appearance. Therefore, she was classified as suffering with pseudohypoparathyroidism type II. The clinical and laboratory abnormalities were improved by calcium supplementation in addition to vitamin D. To the best of our knowledge, this is the first case of pseudohypoparathyroidism combined with Graves' disease in Korea.

Abstract PDF

BACKGROUND
The purpose of this study was to assess the prevalence of thyroid nodules in healthy adults without a history of thyroid disease and the results of fine needle aspiration cytology (FNAC). METHODS: We retrospectively studied 4,832 adults (2,427 women, 2,405 men) over the age of 20 who had visited our health care center from January, 2005, to March, 2008. Subjects with previous thyroid disease were excluded. All were screened by thyroid ultrasonography and FNAC was performed on large or potentially malignant nodules. RESULTS: Thyroid nodules were present in 686 women (28.3%) and 396 men (16.5%), with a female predominance (odds ratio = 1.47, 95% CI = 1.35~1.60). The prevalence of a thyroid nodule was significantly correlated with age in both women and men (P < 0.001). Multinodularity also increased according to age in both groups. Ninety patients were tested with conventional FNAC and 195 underwent ultrasonography-guided FNAC. The rate of inadequate cytology by ultrasonographic guidance was lower than by freehand methods, and the total rate of malignant cytology per patient was 17.9%. Ultrasonographic characteristics that significantly correlated with histologically-confirmed papillary carcinoma included a solid component, hypoechogenecity, irregular margin, and the presence of microcalcification or macrocalcification. CONCLUSION: The prevalence of thyroid nodules detected by ultrasonography was 28.3% in healthy women and 16.5% in healthy men population. The prevalence and multinodularity was significantly correlated with age in both groups. It's useful to examine thyroid by ultrasonography because of detecting more nodules, providing guidance of FNAC, achieving more adequate sampling and not missing small malignant nodules.

Abstract PDF

There have been a few reports on rhabdomyolysis caused by thyroid storm, but no cases of thyrotoxicosis related rhabdomyolysis have been reported until now. Here, a rare case of rhabdomyolysis, accompanied by thyrotoxicosis, is reported. A 21-year-old man was admitted to our hospital with severe pain and weakness in both legs. The initial laboratory findings revealed a high muscle enzyme level and severe hypokalemia. In evaluation of the rhabdomyolysis, the thyroid function test was compatible with that of Graves' disease, with the rhabdomyolysis subsequently diagnosed, presenting as thyrotoxicosis. The possible mechanisms for this complaint were hypokalemia-induced muscle ischemia, a thyrotoxicosis-induced excessive hypermetabolic state and pressure-induced muscle ischemia. Therefore, the work up for the cause of rhabdomyolysis should include thyrotoxicosis. The management of rhabdomyolysis is hydration, prevention of acute renal failure, correction of aggravating factors and treatment of the underlying cause, for example, thyrotoxicosis.

Abstract PDF: A 64-year-old Korean woman presented with a 3-week history of severe headache and ocular pain. Her brain MRI showed a cystic pituitary mass compressing the optic chiasm. A hormonal study revealed anterior pituitary insufficiency and a slightly increased prolactin level. We performed a transsphenoidal resection of the pituitary mass. A pathological examination revealed the presence of a heavy inflammatory infiltrate, composed of lymphocytes and plasma cells, and destruction of the adenohypophysial structures. Five months after surgery, her hormonal levels had nearly normalized, without hormone replacement therapy. A follow-up MRI showed no recurrence. We conclude that lymphocytic hypophysitis should be included in the differential diagnosis of pituitary mass at any age. We discuss the features that can help to make a preoperative differential diagnosis, and selection of the appropriate treatment.

Abstract PDF: Acquired hypophosphatemic rickets, or osteomalacia, requires the recognition of the typical clinical and radiological features of osteomalacia in association with hypophosphatemia, which is caused by the decrease in intestinal absorption or impaired renal tubular phosphate reabsorption. The latter form may either be hereditary or acquired. Acquired hypophosphatemic osteomalacia includes oncogenic osteomalacia, neurofibromatosis, fibrous dysplasia, renal tubular acidosis and sporadic nonfamilial hypophosphatemic osteomalacia. A 33-year-old man presented with bone pain, progressive severe muscle weakness and a height loss of more than 10 cm over a 5 year period. The familiy history was negative for bone disease or other renal tubular defects. He was found to have hypophosphatemia, impaired phosphate reabsorption, normocalcemia, normal vitamin D metabolite levels, normal PTH and elevated alkaline phophatase. A bone biopsy showed thickened unmineralized osteoid compared to pelvic bone in control cases. Clinical symptoms, such as bone pain and muscle weakness, were improved after supplementation of oral phosphorus and calcitriol, although the serum phosphorus level did not normalize.

Abstract PDF: Thyroid dysfunction is one of the more prevalent clinical situations encountered by primary care physicians. Thyroid storm is defined as a life-threatening exacerbation of the hyperthyroid state in which there is evidence of decompensation of one or more organ systems. Common precipitants include infection, surgery, diabetic ketoacidosis, vascular accidents, non-compliance with antithyroid medication, and emotional stress, but rarely develop in invasive molar pregnancy. An 18-year-old woman presented to the emergency department complaining of lower abdominal pain and vaginal spotting. She had no previous history of hyperthyroidism. Under the diagnosis of invasive molar pregnancy, dilatation and curettage was performed. However, right after the procedure the patient developed a semi-coma metal status, high grade fever, and tachycardia. Prompt diagnosis of thyroid storm was made and treatment followed immediately. We present a case of thyroid storm and a review of thyroid storm precipitated by invasive molar pregnancy.

Abstract PDF: BACKGROUND
GH3 cells are a well characterized and widely used model used for the in vitro study of growth hormone (GH) secretion. Thyrotropin releasing hormone (TRH) binds to receptors belonging to the family of G protein-coupled receptors, and secrets both GH & prolactin. Phospholipase D (PLD) is an enzyme that hydrolyses phosphatidylcholine to yield phosphatidic acid and choline, and plays important roles in cellular proliferation and hormonal secretion. To elucidate the pathway of the action of TRH in GH3 cells, we investigated the activities of PLC and PLD in GH3 cells treated with TRH or phorbor 12-myristate 13-acetate (PMA). METHODS: GH3 cells were labeled with [3H] myristate, followed by incubation of with 0.3% ethanol, prior to before the addition of the agonists. The total lipids were extracted from the harvested cells following treatment with the agonists. The PLD activity was assessed by measuring [3H] phosphatidylethanol from the [3H] phospholipid using thin layer chromatography. RESULTS: TRH (1 muM) stimulated the PLC activity by 44-fold over that of the control values. TRH (1 microM), mastoparan (5 muM), and PMA (500 muM) for 30 minutes increased PLD activity by 1.9, 1.5 and 2.2 fold, respectively, in comparison to the controls. The PLD activities after 15, 30, 60, 120 and 240 min treatments of TRH (1 microM) were 142%, 170%, 172%, 160% and 115%, respectively. CONCLUSION: These results suggest that TRH stimulates not only the PLC activity, but also the PLD activity in GH3 cells.

Abstract PDF: Many endocrinologic diseases can induce muscular diseases. Myopathy caused by exogenous steroid is a common problem in patients prescribed steroids as therapy. We report a case of iatrogenic steroid myopathy in a 55-year-old female who had taken steroids under her own volition at a local pharmacy for more than 3 months due to skin rash and itching. She complained of severe proximal muscle wasting and weakness in the lower extremities and also exhibited other stigmata of Cushing's syndrome such as moon face, buffalo hump or easy bruising. Needle electromyography showed the typical pattern of myopathy. Muscle biopsy revealed intermixed numerous, markedly atrophic and angulated basophilic fibers and a few fat cells without inflammation. In addition there was marked and selective atrophy of type II fiber on ATPase staining in pH 9.4 buffer. After discontinuation of steroid treatment, she has experienced slow improvement through physical therapy, including isotonic exercise.

Abstract PDF: Thyroid cancer is the fourth most common malignant tumor in Korean women. It has been acknowledged for a long time that differentiated thyroid cancers have two basic ways of dissemination, lymphtic and hematogenous. Though lymphatic spread to regional lymph nodes is the typical presentation of papillary thyroid cancer of young patients, pulmonary metastasis are not uncommon in this age group. And it is interesting that almost all the patient with metastases to lung showed metastases to the regional neck lymph node. Abnormal chest X-ray of the patient of pulmonary metastasis shows only nonspecific diffuse micronodular pattern which is not easy to be differentiated. And here we report a case of pulmonary metastasis of thyroid papillary carcinoma which was mistaken for pulmonary miliary tuberculosis. It is suggested that more intensive consideration will be necessary for the diagnosis of pulmonary miliaria of children who shows neck mass.

Abstract PDF: Anticonvusant therapy with any of several agents, especially phenytoin, phenobarbital, and primidone causes disturbances in bone mineral metabolism. Anticonvulsants stimulate the hepatic microsomal mixed-oxidase enzymes and hence increase the rate of clearance of vitamin D and its metabolism. The severity of clinical manifestations in any given individual appears to be a function of the combined effects of variety of factors including drug type and total drug dose, dietary vitamin D intake, sunlight exposure, and physical activity level. We report a case of osteomalacia associated with long term carbamazepine therapy in a 21-year-old male with less exposure to sunlight.
