The occurrence of a mixed tumor containing papillary thyroid carcinoma (PTC) and primary squamous-cell carcinoma (SCC) is rare because there is no squamous epithelium in the thyroid gland. Reported herein is a 30-year-old female with mixed PTC and primary sec of the thyroid presented as thyroid incidentaloma. Fine-needle aspiration biopsy of the thyroid nodule revealed the presence of malignant thyroid cells. The histopathological examination following total thyroidectomy yielded two mixed, morphologically distinct histotypes that included PTC and sec. After total thyroidectomy, the patient underwent radioactive iodine therapy. No recurrence or metastasis occurred during the 20-month follow-up period after the operation.

Background and Objectives : The purpose of this study was to evaluate the impact of surgical extent on voice using acoustic and aerodynamic measurements in a serially followed thyroidectomy patients. Materials and Method : From October 2015 to January 2017, 108 patients who had undergone thyroid surgery and voice test for preoperative, 2, 3, and 6 months postoperatively were classified into five operative types. The radiological stage preoperatively and histopathological stage postoperatively were classified according to the invasion of thyroid capsule and surrounding tissue. For each classification, the results of the voice analysis according to the period were compared and analyzed. Results : The difference of voice according to surgical extent, radiological stage, and histopathologic stage showed significant difference only with Maximal phonation time (MPT) over time. However, in the analysis of interaction between each classification and period, Phonation threshold pressure (PTP) only showed significant results. Conclusion : Differences in imaging and histopathologic stages have no significant effect on recovery of voice symptoms after thyroid surgery. As the extent of operation increases, the pressure to start vocalization is relatively higher, which also varies with time after surgery.

Ten patients with $H\"{u}rthle$ cell tumor of the thyroid gland from Dec. 1987 to Sep. 1992 were reviewed to delinate an acceptable policy of treatment. Patients varied from age 23 years to 66 and consisted of nine females and one male, most of whom had an asymptomatic solitary cold nodule. Four patients had benign neoplasm and six patients had malignant neoplasm proven by capsular or vascular invasion or nodal metastasis. Associated thyroid lesions occurred in five patients, three adenomatous goiter, one Graves' disease and one follicular cell carcinoma. Surgery consisting of lobectomy and isthmectomy in four patients, bilateral subtotal thyroidectomy in one patients, total thyroidectomy in five patients. Lymph node dissection was not performed. Only one patient was experienced transient hypocalcemia. The period of observation varied from 15 to 58 months(mean, 30.5 months). Although our case was small and short follow up period, there were no recurrences or deaths. We suggested early aggressive surgical approach was appropriate because of lower recurrence rate and fewer operation, high bilateralism, lower surgical complication.

This study reports a prospective analysis of anatomical variations of recurrent laryngeal nerves during 300 thyroidectomies. During thyroidectomies for variable thyroid diseases. the course of recurrent laryngeal nerve was completely isolated from root of neck to the inferior comus of thyroid cartilage. In left side, nerve(53.7%) predominantly ran posterior to the inferior thyroidal artery(p<0.05) but in right side there was no predominant pattern. There were three nonrecurrent laryngeal nerves in the right side. About half of the cases in both sides(51.2% in right, 50.5% in left side) had one or more branches before terminating at cricothyroidal muscles. The average length of branches from inferior comus of thyroid cartilage to the origination of individual branch were l2.0mm in right side and 13.3mm in left side. In right side, majority(50.7%) of nerves ran though paratracheal space but difference did not reach the statistical but in left side, majority(88.3%) ran through tracheoesophageal groove and it was the dominant pattern(p<0.01), the overall status of passages of the nerve were relatively straight in left side(straight 87.8%, oblique 52.1%).

A 62-year-old female patient had goiter for twenty years. She visited out-patient clinic with a hoarse voice and intermittent breathing difficulties. About protruding 15cm sized mass located the anterior neck and right vocal cord paralysis was observed. Preoperative CT scan was strongly suspected of thyroid gland cancer and cervical lymph node metastasis. Therefore, fine needle aspiration test was performed and surgical treatment was planned with the histopathologic results (papillary thyroid carcinoma). Surgery was performed with total thyroidectomy, bilateral cervical lymph node dissection, and right selective nodal lymph node dissection (level II-V). During operation right thyroid seemed to be adherent to surrounding tissue and the blood vessels were extremely engorged. There was hypotensive crisis because of intraoperative excessive bleeding. However it was managed by repetitive transfusion. The operation was completed without abnormalities. She underwent 4 times of bleeding control operation due to postoperative bleeding. After complications were improved, we are currently undergoing out-patient follow up without morbidity.

Carcinoma arising in a thyroglossal duct cyst is a not common disease. It is detected in approximately 1% of thyroglossal duct cyst, therefore the clinical manifestation of the patient with carcinoma is undistinguishable from the common cystic lesion. Clinically, it may be confounded with a benign lesion and diagnosed after operation. The mainstream of treatment is the Sistrunk operation, however, there is no definite agreement regarding further treatment in addition to an excision of the cyst. The role of total thyroidectomy and the radioactive iodine therapy have been discussed for adjuvant treatment. We have experienced four cases of papillary carcinoma arising in thyroglossal duct cyst. In the three of the cases, the patients underwent Sistrunk operation, while the other one had additional total thyroidectomy and postoperative radioactive iodine therapy. There was no complication in the perioperative period and no signs of recurrence or metastasis during follow-up period.

This study, which is proceeded in the department of nuclear medicine, aims at preventing unnecessary radiation exposure to the patients and the people near the patients by understanding and presenting the realities about the isolating period for the high dose radioiodine patients after total thyroidectomy in the 7 general hospitals in metropolitan area. Theoretically, the physical half-life of the high dose radioiodine is 8 days. Radioiodine lower than 100 mCi usually is eliminated all in 2 days 1 night considering the biological half-life and the amount of excreting radioiodine The hospitalization standard of the patients treated with high-dose radioiodine therapy has been established according to the fact above. Investigation of the data and questionnaire from the hospital have proven that some hospitals didn't even measure the acceptable dose because of the faith in the vague data. Besides, the some of those inevitably let the readmitting patients exceeding the acceptable dose be in the general ward, not in the isolation ward, because the number of the isolation rooms is relatively smaller than the patients. Thus, we want to contribute that patients understand the realities and the hospitals consider the relevant problem actively so that the problem will be settled by this journal.

A thyroglossal duct cyst (TGDC) is the most common congenital anomaly of the neck. However, carcinoma arising from TGDC is extremely rare. We report 2 cases of TGDC carcinoma. In the first case, a 21-year-old male patient complained of an anterior cervical mass; computed tomography (CT) and sonography revealed cystic mass that was suspected to be a TGDC. Sistrunk operation was performed. Papillary carcinoma was confirmed in pathologic examination. Additionally, he underwent total thyroidectomy and central neck dissection. After radioactive iodine ablation (RAI) was performed. In the second case, a 28-year-old male patient visited our out-patient department complaining of submental mass. He had already been diagnosed TGDC carcinoma 13 years ago and had undergone Sistrunk operation and total thyroidectomy. Malignancy was confirmed using fine-needle aspiration; thus, lateral neck dissection was performed and following this, he underwent RAI. Till date, no evidence of recurrence has been observed in these patients.

Purpose: The purpose of this study was to identify the factors associated with the discontinuation of patient controlled analgesia (PCA) after surgery. Methods: The data of 1,092 adult patients that were over 20 years of age and underwent PCA after surgery in the Gachon University Hospital from May 1 to June 30, 2017, were collected through the patients' Electronic Medical Record (EMR). The collected data was analyzed via the use of the Chi-test, t-test and multivariate logistic regression analysis using SPSS 18.0 program. Results: The postoperative PCA discontinuation rate was 26.1%. It was associated with various symptoms, such as those of nausea, dizziness, and headache. The PCA discontinuation was also related with female (odds ratio, OR= 1.75; confidence interval, CI= 1.09-2.82), nausea (OR= 105.27; CI= 61.03-181.58), total intravenous anesthesia (TIVA) of the thyroidectomy (OR= 10.43; CI= 5.01-21.70). Conclusion: It is necessary to provide additional medication and nursing interventions to reduce nausea, which is the symptom associated with PCA discontinuation, especially in the operation of female subjects and thyroidectomy under TIVA. That is, those who are at a high risk for PCA discontinuation should be able to administer additional antiemetics or reduce non medication nursing interventions.
