Hyperthyroidism may be defined as those clinical conditions which result from an increase in the circulating levels of one or both thyroid hormones. Hyperthyroidism in broad sense could be classified with toxic diffuse goiter, toxic adenomatous goiter, and toxic multinodular goiter on the basis of the circulating thyroid hormone levels. For this study, the subject included 94 cases with hyperthyroidism were presented in 77 with toxic diffuse goiter, 8 with toxic adenomatous goiter, and 9 with toxic multinodular goiter on the levels of $^{125}IT_3$ resin uptake rate and serum thyroxine ($T_4$). The observed results were as follows: 1) In the cases of hyperthyroidism including toxic diffuse goiter, toxic adenomatous goiter, and toxic multinodular goiter, 20.21% of the patients were male and 79.79% female. The majority of the patients were in 2nd to 4th decades of their lives. 2) There were objective signs clearly manifested in hyperthyroidism including toxic diffuse goiter and toxic adenomatous goiter which were rare in the multinodular goiter. The clinical signs in toxic diffuse and toxic adenomatous goiter included wide pulse pressure, tachycardia, systolic murmur, exophthalmos, tremor and warm skin etc. (Table 3.) 3) The most freauent complaints of the patients with hyperthyroidism were palpitation, weight loss, increased appetite, perspiration, heat intolerance, nervousness, exertional dyspnea, and menstrual disturbance etc. (Table 4.) There was no clear difference in the incidence of symptoms between toxic diffuse goiter and toxic adenomatous goiter, but there was clear difference between toxic multinodular goiter. 4) Considering of results of $^{125}IT_3$ resin uptake rate and serum $T_4$ level in toxic diffuse goiter, toxic adenomatous goiter and toxic multinodular goiter, $^{125}I\;T_3$ resin uptake rate was $49.15{\pm}9.94%$ (mean) and serum $T_4\;21.29{\pm}7.04ug/dl$ (mean) in toxic diffuse goiter. In toxic multinodular goiter, $^{125}I\;T_3$ resin uptake rate was $32.47{\pm}6.74%$ (mean) and serum $T_4$ level $11.03{\pm}5.0ug/dl$, and then there was clear difference in the results of $^{125}I\;T_3$ resin uptake rate and serum $T_4$ between toxic diffuse goiter and toxic multinodular goiter. The levels of $^{125}I\;T_3$ resin uptake rate and serum $T_4$ in toxic adenomatous goiter were $40.32{\pm}13.08%$ (mean), $15.47{\pm}8.25ug/dl$ (mean) respectively, so there was no clear difference between toxic diffuse goiter and toxic adenomatous goiter. 5) There was no significant differnece in length and width performed with thyroid scanning in toxic diffuse goiter, toxic adenomatous goiter, and toxic multinodular goiter.

Posterior mediastinal goiter extending to carotid sheath posteriorly is rare repoted case. Recently we experienced huge posterior mediastinal goiter with compressin of trachea in 57-year old male, The patient that complained of dyspnea referred to our hospital for further evaluation of mediasitnal tumor. We confirmed huge secondary posterior mediastinal intrathoracic goiter with diagnostic methods following by chest X-ray, thyroid scan, chest CT, and CT guided fine needle aspiration biopsy in this patient, and performed operation for excision Exision of posterior mediasitnal goiter performed through initial transeverse cervical incision and additional median sternotomy, and the mass removed completely without any complications. The postoperative course were uneventful.

Presented here are the results for clinical study on 65 cases of simple goiter the author treated during the period of 4 years and 10 months from Jan. 1963 through Oct. 1967 at the Seoul National University Hospital and Han-Il Hospital. It had been customary to classify simple goiter, according to the gross morphological characteristics of the thyroid gland, as diffuse and nodular type. This paper attempts to investigate the histopathological changes and treatment of simple goiter respectively. Sixty five cases of simple goiter were classified into 4 types; namely degenerative type was 20 cases (30.8%), proliferative type was 7 cases (10..8%), colloidal type was 24 cases (36.9%) and cyst formation with degeneration was 14 cases (21.5%), on the basis of histopathological findings. Thus, it is essential that simple goiter should be differentiated from thyroid tumors as soon as practicable. The effectiveness of medical treatment with desicated thyroid and autohemotherapy for certain simple goiter are also discussed.

A clinical analysis was made on 161 cases of hyperthyroidism seen at the Radioisotope Laboratory of Kyungpook National University Hospital. This series consisted of 144 cases of diffuse goiter and 17 cases of nodular goiter. 1) Hyperthyroidism was most prevalent in the 4th decade and male to female ratio was 1:4.6. 2) Cardinal symptoms in the order of frequency were weakness, easy fatigability, palpitation, weight loss, nervousness, perspiration, heat intolerance, increased appetite, insomnia and dysmenorrhea. 3) Major physical findings in the order of frequency were goiter, fine tremor, tachycardia, wide pulse pressure, emaciation, warm moist skin, exophthalmos, systolic hypertension and atrial fibrillation. 4) The complications were ophthalmopathy (34.2%), thyrotoxic heart disease (5.6%), thyroid crisis (1 case), pretibial myxedema (1 case) and thyrotoxic myopathy (1 case). 5) Mean values of the six hour and twenty-four hour $^{131}I$ uptakes by the thyroid glands were 67.5% and 71.6%, respectively, in diffuse goiter and 64.5% and 65.0%, respectively, in nodular goiter. 6) Mean values of twenty-four hour $PB^{131}I$ conversion ratio were 76.3% in diffuse goiter and 70.2% in nodular goiter and those of the basal metabolic rate was +51% in the former and +41% in the latter. Mean serum cholesterol level was 152mg% in diffuse goiter and that in nodular goiter was 175mg%. 7) Among the 134 cases treated with $^{131}I$, 66 cases (49.3%) were successful1y controlled with single dose and in the majority of the cases the initial therapeutic dose required was $4.1{\sim}5.0mC$ in diffuse goiter and $5.1{\sim}6.0mC$ in nodular goiter. 8) With $^{131}I$ treatment the symptoms improved in the following order: heat intolerance, emaciation, nervousness, insomnia, easy fatigability, weakness, fine tremor, goiter, perspiration, exertional dyspnea and palpitation. And in a few cases improvement of even exophthalmos was seen. 9) Following $^{131}I$ treatment myxedema occurred in 4 cases (3%) and reccurrence in 9 cases (6.8%).

Background: Inflammatory hematological parameters like the neutrophil/lymphocyte (N/L) ratio have been investigated in many cancer types and significant relationships found with prognosis, for example. The aim of this present study was to investigate the impact of hematological parameters notably on N/L ratio and mean platelet volume (MPV) in papillary thyroid cancer cases. Materials and Methods: A total of 79 patients who underwent a thyroidectomy operation in Findikli, Goiter Research and Treatment Center during 2011-2015 period were enrolled in the study, 41 with papillary thyroid cancer and 38 with benign goiter confirmed by pathological examination. We collected clinical and laboratory data for the patients from hospital records retrospectively. Blood samples taken at admission were assessed for parameters compared between the groups. Results: No significant differences between papillary thyroid cancer and benign goiter groups were apparent in terms of age, the N/L ratio, MPV, white blood cell count (WBC), red blood cell count (RBC), hemoglobin, hematocrit, platelet, neutrophil, lymphocyte, red blood cell distribution width (RDW) and platelet crit (PCT) levels (p>0.05). Only the level of platelet distribution width (PDW) significantly differed, being lower in the papillary cancer group (p<0.05). Conclusions: No significant relationship between papillary thyroid cancer and inflammatory hematological parameters including in particular the N/L ratio and MPV. The relevance of the PDW values remains unclear.

Posterior mediastinal goiter extending to carotid sheath posteriorly is rare. Recently we experienced two cases of posterior mediastinal goiter presenting dyspnea due to tracheal compression. The one was a 48-year-old female with mediastinal tumor shadow on chest roentgenogram . The other was a 54-year-old female with palpable mass on neck and huge mediastinal mass. These masses were resected completely through the right posterolateral thoracotomy and median sternotomy respectively. The postoperative courses were uneventful.

Intrathoracic goiters can be classified anterior and posterior mediastinal goiter with its locations. Most intrathoracic goiters are retrosternally situated in the anterior mediastinal compartment. Posterior mediastinal goiters are rare, but might present a difficult diagnostic and surgical problem. Although thyroid goiters are nearly always amenable to a cervical approach, posterior mediastinal goiters may require a combined cervicothoracic approach with sternotomy or thoracothomy. We herein describe a case of posterior mediastinal goiter which was excised only by cervical approach. The relevant literature is briefly reviewed.

A diagnosis of iodine-deficient goiter was confirmed in newborn piglets that were born hairless edematous, and with markedly enlarged thyroid gland. Clinically, most of the piglets were born dead, extreme weakness or dying within a few hours of birth. Gestation periods were prolonged for 3-7 days. Histopathologically, hair follicles were scarce and reduced in size, contained slender hairs, and revealed a shallow penetration into the hypodermis that showed severe diffuse edema. Thyroid glands had severely hyperplastic follicles and poorly staining colloid. The follicles were irregular in size and shape depending on varying amounts of lightly eosinophilic and granular colloid in the lumen. The iodine content of the diet fed to the sows and plasma total thyroxine and triiodothyronine concentration of sows were very low. This is a first report for iodine-deficient goiter in newborn piglets in Korea.

The serum thyroxine levels were measured by method of Tetrasorb Kit in 69 subjects including 13 subjects in euthyroid state, 31 with hyperthyroidism, 5 with hypothyroidism, 13 with nontoxic diffuse goiter, and 7 with nontoxic nodular goiter. Three parameters of the thyroid function test including thyroxine ($T_4$) levels, $^{131}I$ uptake (24 hrs) values and $PB^{131}I$ conversion ratio were correlated with clinical manifestations and courses of the disease. 1. The serum $T_4$ levels in the normal subjects were in range of $6.0{\mu}g/dl\;to\;14.4{\mu}g/dl$. (The mean $9.4{\mu}g/dl$). 2. The diagnostic compatibility of the serum $T_4$ was 93.5% in hyperthyroidism, 100% both in hypothyroidism and in nontoxic diffuse goiter, 86% in nontoxic nodular goiter, or 95.8% in the entire series. (Table 1). 3. The diagnostic compatibility of $^{131}I$ uptake (24 hrs) values and $PB^{131}I$ conversion ratio were less than the serum $T_4$ levels as summarized in Tables 2 & 3. The serum $T_4$ determination by Tetrasorb Kit is a simple, accurate and very useful test of the thyroid function.

Dietary iodine intake and urinary iodide excretion were meassured from 110 patients with various thyroid hormone diseses(hypothyroidism, hyperthyroidism, simple goiter and thyroid adenoma) and 67 normal control subjects. Iodine intake was assessed on the 24-hour recall dietary data using the compiled lists of food iodine values developed from various countries. Urinary iodide concentrations of drink water samples were measured with the iodide-selective electrode. The average iodine intake of the thyroid patients was 411$\mu\textrm{g}$, which was 87% higher(p<0.05) than that of the control subjects(220$\mu\textrm{g}$). Patients with hyperthyroidism and hypothyroidism or simple goiter excreted the most(0.6442ppm) amount of iodide respectively in the urine, with the control subject in the middle(0.5229ppm). Iodide concentrations of the drinking water samples were found to be in the range of 0.0015ppm to 0.0214ppm, which seemed to vary depending on the kind(underground water vs public water) and the location.
