Medullary thyroid carcinoma (MTC) is a rare malignancy that originates from the parafollicular cells of the thyroid gland. Hashimoto's thyroiditis (HT) is an autoimmune thyroid disease and is the most common cause of hypothyroidism. Previous studies have frequently discussed the association among HT, papillary thyroid carcinoma, and thyroid lymphoma. However, there have been few reports on the ultrasonographic findings of concomitant HT and MTC. In the present case, a heterogeneous hypoechoic background parenchymal echogenicity, with intraglandular echogenic strands, and increased vascularity were observed. A concurrent, ill-defined, parallel-oriented, heterogeneous hypoechoic mass with central microcalcifications was located at the left thyroid gland, consistent with reported US findings of medullary thyroid carcinoma except for an ill-defined margin in our case.

The abnormalities in Hypothalamic-pituitary-adrenal(HPA) axis are associated with many psychiatric symptoms including depression. We present a report of a 71 year old man who was admitted to the psychiatric department presenting symptoms of headache, avolition, loss of energy, psychomotor retardation, poor appetite, insomnia, anxiety resulting from adrenal insufficiency and hypopituitarism. Hypothyroidism and electrolyte disturbance were managed and headache, insomnia, anxiety, GI symptoms were improved. But he remained in anergic state. After discharge, he was readmitted to infection department with high fever and drowsy mentality. Adrenal insufficiency was recognized and he was treated with corticosteroid replacement therapy. Finally his diagnosis was made as panhypopituitarism and overall symptoms were resolved. In this case, we showed how the atypical symptoms resulting from hypopituitarism develop and progress. Hypothyroidism, adrenal insufficiency, and growth hormone deficiency resulting secondarily from panhypopituitarism were associated with various nonspecific symptoms such as loss of energy, fatigue, insomnia, weight loss, decreased appetite etc. In clinical situation, differential diagnosis with depression is needed when clinicians were met a patient with these nonspecific symptoms. It is important that laboratory tests and differential diagnosis with endocrine diseases should be conducted, especially in geriatric patients with nonspecific symptoms like anergia, fatigue, poor appetite and so on.

A simplified photoelectric apparatus producing graphic records of the free Achilles tendon reflex allowed us to study the reflex quantitatively in subjects with normal and abnormal thyroid function. In this study Achilles tendon reflex times were tested in 340 normal Korean persons, 89 hyperthyroid patients, 19 hypothyroid patients and 85 other thyroid disease patients who were euthyroid in thyroid function tests. In normal Korean persons, the Achilles tendon reflex time was delayed with increasing age and slower in female than in male. They showed good correlationship with various thyroid function tests which included ETR, $T_3RU,\;^{131}I$ thyroid uptake and serum TSH. Diagnostic accuracy of them was 71% in hyperthyroidism and 90% in hypothyroidism. Finally the serial measurements of them were very useful tests in evaluating the clinical coures of hyperthyroidism and hypothyroidism once treatment was begun.

Postpartum depression(PPD) of women with depression increased frequency of thyroid disease, and so the correlations for depression and thyroid disease has been the subject of discussed whether. The purpose of this study was to predict the prevalence of PPD and the correlation between PPD and thyroid disease through ultrasonography. January 2010 to November 2011, Obstetrics & Gynecology in M-clinical center admitted 230 patients within 1 year postpartum were enrolled. EPDS by PPD scale depression screening and general characteristics of subjects were investigated and thyroid was examined that ultrasonography and thyroid blood tests. A total of 230 patients non PPD group were 53.0% and PPD group were 47.0%. In ultrasonography, among 27 patients who changed in size of thyroid, non PPD group were 14.8% and PPD group were 85.2%. Among 124 patients who thyroid nodules were presence, non PPD were 35.8% and PPD group were 64.2%. In ultrasonography, PPD group were higher incidence than non PPD group were changes in size of thyroid and the presence of nodules. There was significant difference between the changed in size of thyroid and thyroid nodules were presence the two group. Definitive histopathological diagnosis was benign in 33 patients (non PPD group were 45.5%, PPD group were 54.5%), malignancy in 5 patients (only PPD group were 100%), thyroiditis in 3 patients (non PPD group were 33.3%, PPD group were 66.7%). The results of thyroid blood tests, abnormal TSH level were 7 patients (non PPD group were 28.6%, PPD group were 71.4%) and abnormal Free T4 level were 9 patients (non PPD group were 44.4%, PPD group were 55.6%). There was no significant difference between the abnormal TSH level and Free T4 level of the two group. 5 patients were diagnosed as thyroid dysfunction. Of these, 2 patients were subclinical hyperthyroidism in non PPD group, 2 patients were subclinical hyperthyroidism and 1 patient was subclinical hyperthyroidism in PPD group. This study was significant the correlation between PPD and thyroid gland disease through ultrasonography. And the objective results of this study might be able to provide guideline that understanding, prevention and treatment for PPD and thyroid disease.

Radioiodine($^{131}I$) has been used for the treatment of Graves' hyperthyroidism since the late 1940's and is now generally regarded as the treatment of choice for Graves' hyperthyroidism who does not remit following a course of antithyroid drugs. But for the dose given, several different protocols have been described by different centers, each attempting to reduce the incidence of long-term hypothyroidism while maintaining an acceptable rate control of Graves' hyperthyroidism. Our goals were to evaluate effective half-life and predict absorbed dose in Graves' hyperthyroidism patients, therefore, to calculate and readminister radioiodine activity needed to achieve aimed radiation dose. Our data showed that the mean effective $^{131}I$ half-life for Graves' disease is 5.3 days(S.D=0.88) and mean biologic half-life is 21 days, range 9.5-67.2 days. The mean admininistered activity and the mean values of absorbed doses were 532 MBq(S.D.=254), 112 Gy (S.D.=50.9), respectively. The mean activity needed to achieve aimed radiation dose were 51MBq and marked differences of $^{131}I$ thyroidal uptake between tracer and therapy ocurred in our study. We are sure that the dose calculation method that uses 5 days thyroidal $^{131}I$ uptake measurements after tracer and therapy dose, provides sufficient data about the effective half-life and absorbed dose of $^{131}I$ in the thyroid and predict the effectiveness of $^{131}I$ treatment in Graves' hyperthyroidism.

In order to evaluate the significance of thyrotropin-binding inhibiting immunoglobulin (TBII) in the patients with autoimmune thyroid diseases, the authors investigated 402 cases of Graves' disease and 230 cases of Hashimoto's thyroiditis comparing 30 cases of normal healthy adult at Kyung Pook University Hospital from February 1993 to August 1994. The TBII was tested by radioimmunoassay and assesed on the dynamic change with the disease course, thyroid functional parameters, and other thyroid autoantibodies : antithyroglobulin antibody (ATAb) and antimicrosomal antibody (AMAb) including thyroglobulin. The serum level of TBII was $40.82{\pm}21.651(mean{\pm}SD)%$ in hyperthyroid Graves' disease and $8.89{\pm}14.522%$ in Hashimoto's thyroiditis and both were significant different from normal control of which was $3.21{\pm}2.571%$. The frequency of abnormally increased TBII level was 92.2% in hyperthyroid Graves' disease, 46.7% in euthyroid Graves' disease or remission state of hyperthyroidism, and 23.9% in Hashimoto's thyroiditis. The serum levels of increased TBII in Graves' disease were positively correlated with RAIU, serum T3, T4, and FT4, but negatively correlated with serum TSH(each P<0.001). The TBII in Graves' disease had significant positive correlation with serum thyroglobulin and AMAb, but no significant correlation with ATAb. In the Hashimoto's thyroiditis, the serum levels of TBII were positively correlated with RAIU, serum T3, TSH and AMAb, but not significantly correlated with serum T4, FT4, thyroglobulin and ATAb. Therefore serum level of TBII seemed to be a useful mean of assessing the degree of hyperthyroidism in Graves' disease and correlated well with thyroidal stimulation. The serum level of TBII in Hashimoto's thyroiditis is meaningful for the degree of both functional abnormality reflecting either hyperfunction or hypofunction and the immune logic abnormality.

Serous effusions have been most commonly associated with ascites, pericardial effusion, and heart failure. But, they have been considered to be an unusual form of complication in hypothyroidism and pleural effusion, which has been observed as an isolated finding in hypothyroidism is apparently rare and complete analysis of these types of hypothyroid-associated pleural effusions has yet not been described. We report a case of hypothyroidism associated with unilateral pleural effusion in a 77 year-old male patient who was improved through levothyroxine sodium with brief review of the literature.

In pseudohypoparathyroidism as reported by Albright in 1942, the parathyroid gland can normally synthesize and secrete parathyroid hormone(PTH). Pseudohypoparathyroidism has a similar biochemical finding with hypoparathyroidisms like hypocalcemia and hyperphosphatemia due to target tissue resistance to PTH. Administered PTH does not raise the serum levels of calcium and urinary phosphate. PTH activates G-protein in peripheral tissue and adenylate cyclase through a second messenger, cAMP. Pseudohypoparathyroidism produces hyperphosphatemia and hypocalcemia because of the resistance to PTH in peripheral tissue due to a defect of G-protein, although it releases PTH normally. According to the mechanism of resistance, pseudohypoparathyroidism is classified into types : Ia, Ib, Ic and psedopseudohypoparathyroism. Type Ia is accompanied by congenital growth retardation and abnormal bony development that shows mental retardation, obesity, low height, round face, short metacarpal bone and metatarsal bone, ectopic calcification, etc. We report a case of pseudohypoparathyroidism in a premature who shows hypocalcemia, hyperphosphatemia, elevation of serum PTH and 24 hr urinary basal c-AMP in biochemical tests without Albright's hereditary osteodystrophy at physical examination, accompanied by a spontaneous fracture in the femur.
