Objectives: Three classic treatment modalities have been used to treat Graves' disease: antithyroid medication, radioiodine ablation, and subtotal thyroidectomy. Postoperative thyroid functions were studied in patients with Graves' disease treated by subtotal thyroidectomy to evaluate the superiority of surgical treatment. Materials and Methods: One hundred fourty patients of Graves' disease were analysed retrospectively in follow-up for more than three years following subtotal thyroidectomy. Postoperative serum levels of $T_3,\;T_4, TSH, TSH-R Ab, free $T_4$, were evaluated to watch hypo- or hyperthyroidsm. Results: In the evaluation of preop- and postoperative thyroid function after three years of subtotal thyroidectomy, $T_3$ was changed from $464.10{\pm}196.16ng/dl$ to $140.41{\pm}76.56ng/dl$ in mean value, $T_4$ was changed from $20.76{\pm}7.98{\mu}g/dl$ to $9.54{\pm}4.02{\mu}g/dl$, $TSHT_3$ was changed from $0.55{\pm}4.42{\mu}u/ml$ to $4.96{\pm}7.20{\mu}u/ml$, TSH-R Ab was changed from $41.6{\pm}28.27%$ to $28.7{\pm}28.79%$ and free $T_4$ was changed from $4.45{\pm}2.33ng/dl$ to $1.44{\pm}0.69ng/dl$ in mean value. Euthyroidism was noted in 118 patients(84.3%), overt hyperthyroidism in 6 patiens(4.3%), latent hyperthyroidism in 8 patients(5.7%), overt hypothyroidism in 2 patint(1.4%), and latent hypothyroidism in 6 patients(4.3%). Of surgical complications, permanant hypoparathyroidism was found in one patient, recurrent laryngeal nerve injury in two patients, postoprative bleeding with reoperation in two patients, and death in one patient. Conclusion: The thyroid function after subtotal thyroidectomy in diffuse toxic goiter is normal level (euthyroidism) in 84.3% and low recurrence rate of hyperthyroidism is showed with rare surgical complication. Therefore, subtotal thyroidectomy in diffuse toxic goiter is more effective and safe than RI or longterm ATD treatment, if the operation is performed by skillful surgeon.

The prevalence of thyroid disease, particularly hyperthyroidism, has rapidly increased in Korea in the past 10 years. Therefore, it is important to consider the complete medical history including thyroid disease in patients under dental treatment. Both the drugs used for dental treatment and psychological symptoms associated with treatment can induce emergencies in hyperthyroid patients. This case report considers emergency situations during dental treatment for hyperthyroid patients, and discusses risk factors and related concerns.

The voice of aged persons is known generally to be somewhat different from that of other adults, suggesting that laryngeal change occurs with advancing age. However, because knowledge of the voice characteristics of aged persons is limited, it is difficult to judge whether their voices arc normal. Chart review and laryngoscopic examination from ninety-one patients with hoarseness over the age of 60(1st group) and one hundred sixteen patients with hoarseness below the age of 50(2nd group) were done to define aging related voice disorders. The following results were obtained. 1) Associated diseases related to laryngeal disease were hypertension(12%), pulmonary disease(4.4%), thyroid disease(1.1%) in 1st group and hypertension(9.5%), thyroid disease(1.7%) in 2nd group. 2) The underlying diseases causing hoarseness in order of frequency were benign vocal fold lesion(37.7%), inflammatory disease(36.8%), functional dysphonia(17%) in 1st group and benign vocal fold lesion(43.6%), functional dysphonia(26.3%), inflammatory disease(16.5%) in 2nd group. 3) In stroboscopic findings, atrophy and sulcus of vocal cords are more prevalent in males than in females and edema of vocal cords is more common in females. Generally the voice characteristics of aged persons depend on the mass of the vocal folds which may be decreased through atrophy or be increased by edema. However, other factors such as systemic diseases, drug side effects and compensatory mechanism to presbylaryngis must be taken into account in diagnosing and treating voice disorders in aged persons.

Anaplastic carcinoma of thyroid gland account for no more than 10% of thyroid cancer, but it shows extremely poor prognosis. The purpose of this study is to review the outcome of patients with anaplastic carcinoma over the span of 5 years and to determine the patterns of clinical presentation, age, sex and other possible prognostic variables. We analyzed 30 cases of anaplastic carcinoma retrospectively from 1991 to 1995. There were 14 men and 16 women. There age ranged 33 to 75 years with a mean of 61.0 years. Sixteen patients presented with transformationqr of well differentiated carcinoma to anaplastic carcinoma, 1 with rapid in-crease in the size of long standing goiter, 8 with rapidly growing neck mass and 4 with meta static disease. Twenty-eight patients(93.3%) showed cervical lymphnode metastasis at presentation and twenty three patients(76.6%) showed laryngotracheal invasion. Nine patients (30.3%) showed distant metastasis. Treatment modalities included surgical resection, external irradiation, radioactive iodine and systemic chemotherapy. At decision making of treatment plan, we considered completeness of initial surgery, uptake rate of whole body radioactive io-dine scan, locoregional progression and distant metastasis. The median survival was 6.8 months and three cases survived beyond 12 months.

Metastases to regional cervical lymph nodes occur frequently in patients with thyroid cancer. The appropriate management of regional lymph node is important to achieve good disease control and to classify risk stratification for adjuvant radioactive iodine. However, there are some occasions that neck dissection is difficult and embarrassing in thyroid cancer. Especially, extensive or unusual nodal metastases bring challenges and makes neck dissection more difficult. Carotid artery management is one of the most difficult procedure in neck dissection. The management of patients who have persistent or recurrent cervical metastasis involving the carotid artery has been controversial and treatment dilemma to the surgeon. Metastasis of well differentiated thyroid cancer to the retropharyngeal lymph nodes is rare but occasionally encountered. The complete surgical excision is usually recommended for retropharyngeal lymph node metastasis of well differentiated thyroid cancer. An extensive mediastinal dissection in advanced differentiated thyroid carcinoma is occasionally required. This paper will review recent reports of management of advanced nodal metastasis of thyroid cancer and share the author's personal experience.

Thyroid eye disease (TED) is a complex autoimmune disease with a spectrum of signs. we previously reported that trisialoganglioside (GT)1b is significantly overexpressed in the orbital tissue of TED patients, and that exogenous GT1b strongly induced HA synthesis in orbital fibroblasts. However, the signaling pathway in GT1b-induced hyaluronic acid synthase (HAS) expression in orbital fibroblasts from TED patients have rarely been investigated. Here, we demonstrated that GT1b induced phosphorylation of Akt/mTOR in a dose-dependent manner in orbital fibroblasts from TED patients. Both co-treatment with a specific inhibitor for PI3K and siRNA knockdown of TLR2 attenuated GT1b-induced Akt phosphorylation. GT1b significantly induced HAS2 expression at both the transcriptional and translational level, which was suppressed by specific inhibitors of PI3K or Akt/mTOR, and by siRNA knockdown of TLR2. In conclusion, GT1b induced HAS2 in orbital fibroblasts from TED patients via activation of the PI3K-related signaling pathway, dependent on TLR2.

Introduction : Although bilateral exploration has been thought to be the standard therapeutic modality for primary hyperparathyroidism(pHPT) due to the admirable cure rate, questions have remained as to whether bilateral neck exploration for all patients with pHPT is needed because 80-85% of patients with pHPT have a single parathyroid adenoma. If the diseased parathyroid can be determined preoperatively, a directed and minimal operation is appropriate using the recent innovations of preoperative diagnosis and operation techniques for parathyroid diseases, the radio-guided parathyroid surgery(RGPS) is one of the standards. In especial, RGPS has been reported beneficial in special circumstances, such as in recurrent disease, ectopic parathyroid, and in mediastinal parathyroid. It can be also useful for the parathyroid disease in previously explored or irradiated neck. Material and Methods : We experienced 2 cases of pHPT successfully treated by RGPS in who previously underwent extensive neck dissection and concomitant external or internal radiotherapy. We adopted and modified the technique described by Dr. James Norman at the University of South Florida-the minimally invasive parathyroidectomy using intraoperative nuclear mapping with 99mTc-sestamibi scanning and radioactivity detection probe. Results : We acquired the successful results for these patients. Conclusion : RGPS is thought to be the alternative technique for the patients with prior central neck exploration and irradiation.
