Targeted therapy has been proven to be one of the most effective cancer treatments. However, some endocrine disorders can occur during treatment with targeted agents. We report the case of a patient who exhibited a wax and wane pattern of hypoglycemia that was attributed to sorafenib therapy. A 32-year-old woman with metastatic hemangiopericytoma visited the emergency department in a stuporous state. Nonhyperinsulinemic hypoglycemia was diagnosed, was exacerbated shortly after sorafenib therapy, and was improved by the cessation of sorafenib with additional glucocorticoid therapy. Patients with metastatic hemangiopericytoma should be carefully monitored with particular attention to hypoglycemia when sorafenib therapy is initiated.

AbstractAbstract 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.

AbstractAbstract PDF
Familial combined hyperlipidemia is one af the manogenic disorders frequently found in humans and is seen in 0.5~2% of the general populatian, accounting for at least 10% of persons with pemature atlmmcletusis. The distinguishing feature of familial combined hyperlipidemia, in camparison with other single-gene abnarmalities of lipoprotein metabolism, is that not all affected members have the same plasma lipid phenotype; some individuals have an elevation of cholesterol concentration alane(type IIa lipoprotein pattern), while some athers have an elevation of triglyceride concentration alone(type IV pattem), and still others have elevations of both values(type IIb pattem). In any one persan, the lipid phenotype can change as a result of dietary or drug treatment. Familial combined hyperlipidemia should be suspected in those subjects with moderate hypertriglyceridemia and/or moderate hypercholestaolemia (lipoprotein types IIa, Ilb, IV), especially when premature coronary heart disease is evident in the family histary. Low plasma HDL-cholesterol, obesity, insulin resistance and hyperuricemia are often . Family members affected by familial combined hyperlipidemia should be identified and be treated, since tbe condition is associated with premature caronary heart diasease. We have found one family of familial combined hyperlipidemia with one member(case 1) associated with insulin resistance, hyperuricemia and gout, and another member(case 2) associated with diabetes mellitus and infertiTity.

AbstractAbstract PDF
The thiourea derivatives, propylthiouracil and methimazole are in widespread use for the treatment of hyperthyroidism. The untoward side effects of these drugs are not infrequent and agranulocytosis is the most serious side effect them. We observed one case of methimazole induced agranulocytosis complicated by deep neck abscess. A 54-year-old woman was admitted because of fever, chilling and sore throat for 1 week. The symptom was developed after receiving methimazole 30mg daily day due to hyperthyroidism during last 3 months. Physical examination revealed hyperemic, enlarged tonsils and tender swelling of the right lower neck The peripheral blood total leukoeyte count was 1,500/mm' (absolute neutrophil count, ANC 9) and a peripheral blood smear revealed few neutrophil. The patient was administered G-CSF 2 mg/kg daily, and on the fifth day of hospitalization, fever subsided and ANC increased to 3,431. On the 11th day, fever developed again and the tenderness and swelling in both lower neck area were aggrevated. Computed tomography of the neck was performed, and revealed a large deep neck abscess. After pus aspiration and antibiotics therapy, the neck abscess was disappeared.

AbstractAbstract PDF
The several forms of treatment of Graves disease-thyroidectomy, antithyroid drugs and radioiodide therapy-are in wide use now. But which therapy is best is a matter of debate. Some authors reported that in patients who underwent thyroidectomy, higher titers of serum antimicrosomal antibody were associated with 1) higher formation rates of germinal centers, 2) more lymphocyte infiltration in the thyroid tissue, 3) higher incidence of hypothyroidism, and 4) lower incidence of recurrence. We were interested in the relationship of thyroid autoantibody titers, ADCC(antibody-dependent cell-mediated cytotoxicity) activity and the clinical response to antithyroid medication. METHODS: We measured ADCC activities from patients in Graves disease(n-48), Hashimoto thyroiditis(n=17) and normal control(n=9). The patients of Graves disease were followed up for more than 1 year, and they were grouped into A(n=17, well responsed group to antithyroid medication) and B(n=31, poorly responsed group). We examined ADCC activities of patients' sera by chromium release assay. RESULTS: 1) Mean age of patients with Graves disease was 34.4210.4 years and 15 patients were male(31%). 2) Results of thyroid function tests of the Graves' patients were T 585.9 +/- 255.3 ng/dL, T4 21.3 +/- 12.2 mg/dL, TSH 0.11 +/- 0.06mIU/mL. Concentrations of antimicrosomal antibody, antithyroglobulin antibody and thyrotropin binding inhibitory immunoglobulin were 1279.1 +/- 1486.7 IU/mL, 488.1 +/- 751.1 IU/mL, and 38.5 +/- 33.4U/L respectively. 3) There was no significant difference between levels of thyroid hormones or concentrations of thyroid autoantibodies and ADCC activities in graves patients. 4) The ADCC activity of the Graves patient group(24.49%) was significantly higher than that of the normal control group(3.76%), and significantly lower than that of the Hashimotos thyroiditis group(36.34%). 5) There was no significant difference in ADCC activity between group A(18.24 +/- 13.44%) and B(27.91 +20.02%). CONCLUSION: From this results, we suggested that ADCC activity seems to be no value as a prognostic factor in predicting the response to antithyroid drugs in Graves disease patients. But, further studies, larger number of patients and long-term follow up, are needed.

AbstractAbstract PDF
Klinefelter syndrome is one of the most common forms of primary hypogonadism and infertility in males. It is a clinical syndrome consisting of gynecomastia, azoospermia, and increased urinary excretion of follicle-stimulating hormone. Fequency of diabetes mellitus, emphysema, asthma, breast cancer increase in Klinefelter syndrome. We report a 16-year-old male patient with impaired glucose tolerance in association with Klinefelter syndrome, which was confirmed by chromosome analysis. The mechanism of impaired glucose tolerance in this patient was peripheral insulin resistance which clarified by euglycemic hyperinsulinemic clamp test.

AbstractAbstract PDF
Langerhans cell granulomatosis(LCG), previously termed 'Histiocytosis-X', is one of the rare disease. LCG is characterized by proliferation of Langerhans cells in a unifocal or multifocal pattern. And LCG may be manifested in a variety of way, ranging from a spontaneously regressing solitary lesion to a multisystem life-threatening disorder. This disease usually involves the bone, lung, skin and lymph node. The most common endocrinologic abnormalities in LCG are diabetes insipidus and growth hormone deficiency. LCG involving the thyroid gland is extremely rare and only a small numbers of cases have been reported worldwide. A 41-year-old diabetic female visited the hospital due to the neck swelling for 3 months and she also complained of polyuria, polydipsia and easy fatigue. LCG involving multiple organs included thyroid gland was diagnosed by high-resolution CT of lung, by characteristic histological findings of the thyroid lesion and by the immunohistochemical staining for S-100 protein and OKT 6(CD la). She is followed at OPD without any medication.

AbstractAbstract PDF
Primary squamous cell carcinoma of the thyroid is rare, presenting much less than one percent of all primary thyroid malignancies. Most cases have been reported in elderly patients with a history of goiter. It is necessary to differentiate between primary squamous cell carcinoma and secondary involvement from other sites. Secondary involvement of the thyroid may be more amenable to palliation or cure. The treatment of choice in primary squamous cell carcinoma is radical surgery in resectable cases, but the squamous cell carcinoma behaves aggressively and carries a uniformly poor prognosis regardless of the treatment. We had an experience of a primary squamous cell carcinoma of the thyroid in two elderly patients. These patients presented a typical feature of a primary squamous cell carcinoma of the thyroid, which has been rarely reported in Korea.
