We analyzed Radioisotope scan findings of 46 patients of thyroiditis which were proven pathologically at K.C.H. The results were as follows 1) 45 patients were female, one was male and average age of patients was 37 years old. 2) The lesion site was predominant in both lobe (67%) 3) Hashimoto's thyroiditis showed enlarged thyroid (85%) with cold nodule (20%), diffuse decreased activity (10%), while subacute thyroiditis was presented absent activity (53%), poor visualization (20%) or cold nodule (7%) 4) Radioisotope scan was valuable in evaluations function of thyroid gland and detection of lesion but there was a limit of pathological nature.

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.

For discrimination of ductal and ascinar cells, we isolated a single-chain variable domain fragment (scFv) antibody against ductal cells of salivary gland using phage display technique. From the spleen of a mouse immunized with ductal cell lysate, total RNA was prepared and used as a template for cDNA synthesis of antibody genes. The scFv genes were constructed with variable domain genes of heavy and light chain and were introduced into pCANTAB5E to construct phage scFv library. The phage particles specific for acinar cells were screened by subtraction using immunotubes coated with acinar and ductal cell lysate and enzyme-linked immunoabsorbance assay (ELISA). The characteristics of the scFv were determined by immunohistochemistry (IHC) and the result indicated that the isolated scFv has the specificity against ductal cells of salivary glands and tubules of kidney. And the scFv has an unique binding activity specific for Hashimoto's thyroiditis. The nucleotide sequence of isolated scFv gene was determined and revealed that V/sub H/ belongs to the mouse H-chain family subgroup IB and V/sub L/ to the mouse L-chain family subgroup III.

Objectives: The aim of this paper was to aid Korean clinical practices for determining clinical and subclinical hypothyroidism and to identify further relevant studies by summarizing the present domestic clinical studies. Methods: The research consisted of a review of articles up to July, 2018 found by searching 'Hypothyroidism' and 'Hashimoto's thyroiditis' as keywords in five domestic electronic databases. Results: Only nine studies satisfied the selection criteria and were analyzed. These included six case reports, two controlled clinical trials, and one randomized controlled trial. Of these, Anjeonleejoong-tang was the most frequent herbal medicine used to treat hypothyroidism. Conclusions: Systematic and large-scale research studies are needed to standardize the guidelines for traditional Korean treatment of hypothyroidism.

Autoimmune thyroiditis is the most common cause of hypothyroidism in the world. It is characterized clinically by gradual thyroid failure, goiter formation, or both, because of the autoimmune-mediated destruction of the thyroid gland. Renal involvement presenting proteinuria in autoimmune thyroiditis is not uncommon, occurring in 10% to 30% of the cases. Glomerulonephropathy associated with autoimmune thyroiditis, however, is a rare disease. Most reports of autoimmune thyroiditis with glomerulonephropathy have demonstrated a mixed pathological morphology and have been predominantly associated with membranous glomerulopathy. The case of minimal-change disease associated with thyroiditis presenting acute kidney injury is a rare disease that has not been reported in South Korea. Reported herein is the case of a 16-year-old man diagnosed with Hashimoto's thyroiditis, with minimal-change disease presenting acute kidney injury. He revealed hypothyroidism, proteinuria, and impaired renal function. Renal biopsy showed minimal-change disease and minimal tubular atrophy. The patient was treated with thyroid hormone, and his renal function and proteinuria improved. Therefore, for patients with autoimmune thyroiditis presenting unexplained proteinuria, glomer-ulonephropathy should be ruled out. Conversely, for patients with glomerulonephropathy and persistent proteinuria despite proper treatment, thyroid function and antibody tests should be performed.

Primary thyroid lymphoma is a relatively rare thyroid tumor and usually a non-Hodgkin type. Its most common histologic type is the diffuse large B cell lymphoma followed by mucosa-associated lymphoid tissue(MALT). It is known to be frequently associated with autoimmune thyroiditis such as Hashimoto's thyroiditis. We report three cases of thyroid lymphoma at a single institution with are view of the literature.

Background: Human papillary thyroid carcinoma (PTC) is often associated with Hashimoto's thyroiditis (HT); their coexistence improves PTC prognosis. Osteopontin, a secreted glycoprotein, plays a role in cell survival, immunity, and tumor progression, its expression being associated with a poor prognosis and metastasis in several malignancies. Osteopontin overexpression correlates with aggressive clinicopathological features in PTC. Lymph node metastases and large tumor size positively correlate with osteopontin positivity. This study aimed to: (1) confirm osteopontin overexpression in human PTC samples; (2) compare osteopontin expression levels in PTC cases with and without HT; and (3) identify correlations between tumor aggressiveness and osteopontin expression levels. Materials and Methods: Plasma osteopontin was assessed in 45 patients with PTC, 22 patients with PTC and HT, and 24 healthy controls by enzyme-linked immunosorbent assay. Thyroid tissue osteopontin mRNA and protein levels were analyzed by reverse transcription-polymerase chain reaction and Western blotting, respectively. Results: Plasma osteopontin levels were significantly higher in PTC patients than in healthy controls. Plasma osteopontin, tissue osteopontin mRNA, and tissue osteopontin protein levels were significantly lower in patients with PTC and HT than in those with PTC alone. In advanced disease stage cases, osteopontin mRNA and protein expression levels were lower in patients with PTC and HT than in those with PTC alone. However, the osteopontin expression level was not significantly associated with the TNM stage. Conclusions: Plasma osteopontin, tissue osteopontin mRNA, and tissue osteopontin protein levels were significantly lower in patients with PTC and HT than in those with PTC alone, suggesting that HT attenuates PTC aggressiveness through negative regulation of osteopontin expression.

Lymphoid infiltration can be seen in some lesions such as Hashimoto's thyroiditis, subacute thyroiditis and several neoplasm of the thyroid. In case of malignancy, there are a few reports of lymphoid infiltration in the diffuse sclerosing variant of papillary carcinoma. But heavy lymphoid infiltraton without evidence of sclerosis is uncommon. We experienced a case of papillary oxyphilic carcinoma with massive lymphoid infiltration, which looks like Warihin tumor of salivary gland. However cytological feature of epithelial cells exhibit that of papillary carcinoma.

Background: The objective of this study was to investigate the MSCT characteristics of PTL in order to enhance the awareness of this uncommon entity among both clinicians and radiologists. Materials and Methods: The clinicopathological data and MSCT images of 27 patients with PTL were retrospectively reviewed. The MSCT appearances were classified into three types: type 1, solitary nodule surrounded by normal thyroid tissue; type 2, multiple nodules in the thyroid, and type 3, enlarged thyroid glands with a reduced attenuation with or without peripheral thin hyperattenuating thyroid tissue. Results: The patients were enrolled in the study with a mean age of 68 years (range, 51-86years) and compression symptoms or enlarged cervical lymph nodes at diagnosis. Hashimoto's thyroiditis was in 20 patients. All patients had non-Hodgkin lymphoma of B-cell in origin, including 22 cases of diffuse large B-cell lymphoma (DLBCL) and 5 of low-grade B-cell lymphoma of mucosa-associated lymphoid tissue (MALT). For MSCT appearance, type 1 pattern was observed in 2 patients, type 2 in 8, and seventeen type 3 in 17. The lesions occurred in more than one lobe with a mean maximal transverse diameter of 6.9 cm and an ill-defined margin. Most tumors showed a homogeneous attenuation equal to that of surrounding muscles before contrast and obvious enhancement after contrast. Cervical lymph node involvement and invasion of the trahea and (or) esophagus were mainly observed in patients with DLBCL. Conclusions: PTL should be clinically considered in elder patients presenting with a history of Hashimoto's thyroiditis and cervical lymphadenopathy. The MSCT characteristics of PTL includes a mass diffusely affecting more than one thyroid lobe, isointense to muscle and obvious enhancement before and after contrast. DLBCL, the most common histological subtype of PTL, is associated with a higher invasive tendency.

The diffuse sclerosing variant of papillary thyroid carcinoma (DSPTC) is uncommon. Herein, we report a rare case of DSPTC in a 9-year-old girl who initially presented with a painless diffuse goiter. Thyroid peroxidase antibody testing yielded positive results, and the initial clinical diagnosis was Hashimoto's thyroiditis. However, thyroid ultrasonography revealed characteristic findings of DSPTC, which was confirmed through the postoperative histopathological diagnosis. Although thyroid cancers are rare in the pediatric population, DSPTC should be included in the differential diagnosis of goiter in these patients. Moreover, ultrasonography may prevent a diagnostic delay and facilitate the detection of a concomitant malignancy.
