Pyogenic liver abscess in patients with malignant disease is a fatal state and is easily diagnosed. We presented a rare case of sudden fatal septicemia following anticancer treatment for recurred gastric cancer due to multiple liver abscesses which could not be diagnosed. A 72-year-old male with recurred gastric cancer received anticancer agents. He had a history of distal gastrectomy with right hepatic lobectomy for hepatic metastasis. He received anticancer treatment in the outpatient's service center periodically, and his performance status was preserved with nothing in particular. After administrating docetaxel, he suddenly developed septicemia and multiple organ failure and died 5 days after strong medical supports. Pathological autopsy revealed that multiple minute abscesses of the liver which could not be detected macroscopically were the causes of fatal septicemia. The etiology, therapies and prognosis of rare entity are being discussed.

Purpose: Thyroid dysfunction is common in preterm infants. Congenital hypothyroidism causes neurodevelopmental impairment, which is preventable if properly treated. This study was conducted to describe the characteristics of thyroid dysfunction in very low birth weight infants (VLBWIs), evaluate risk factors of hypothyroidism, and suggest the reassessment of thyroid function with an initially normal thyroid-stimulating hormone (TSH) as part of a newborn screening test. Methods: VLBWIs (January 2010 to December 2012) were divided into two groups according to dysfunction-specific thyroid hormone replacement therapy, and associated factors were evaluated. Results: Of VLBWIs, 246 survivors were enrolled. Only 12.2% (30/246) of enrolled subjects exhibited thyroid dysfunction requiring thyroid hormone replacement. Moreover, only one out of 30 subjects who required thyroid hormone treatment had abnormal thyroid function in the newborn screening test with measured TSH. Most of the subjects in the treatment group (22/30) exhibited delayed TSH elevation. Gestational age, Apgar score, antenatal steroids therapy, respiratory distress syndrome, patent ductus arteriosus, sepsis, intraventricular hemorrhage, postnatal steroids therapy, and duration of mechanical ventilation did not differ between the two groups. Birth weight was smaller and infants with small for gestational age were more frequent in the treatment group. Conclusion: Physicians should not rule out suggested hypothyroidism, even when thyroid function of a newborn screening test is normal. We suggest retesting TSH and free thyroxine in high risk preterm infants with an initially normal TSH level using a newborn screening test.

Background: Epidemiological data on thyroid cancer and associated risk factors are scarce in our setting. The present study was therefore designed to gather data which could be helpful in providing insights to thyroid physicians and surgeons for better management of affected patients. Purpose: To determine the frequency of carcinoma thyroid among patients presenting with goiter and its association with TSH, Tg/ATg and other demographic factors. Materials and Methods: A total of 73 adult patients of either gender with solitary solid cold nodules and/or multi-ndoular goiter (MNG) with predominant solid cold nodules were enrolled. All surgically resected samples were sent for histopathology. The frequency of thyroid cancer and its subtypes was noted and tested for association with gender, age (< or ${\geq}40years$), recent increase in swelling size, TSH, Tg and ATg. Results: Thyroid cancer was diagnosed in 26% (n=19) of the patients, 14 (73.7%) being diagnosed with papillary thyroid cancer and 5 (26.3%) with follicular thyroid cancer. No other subtypes were noted. Presence of thyroid cancer was significantly associated with recent increase in swelling size and higher TSH Values mean TSH values (P<0.05). No significant association was found with gender, age, Tg and ATg values (P>0.05). Conclusions: Overall percentage of thyroid cancer in our study sample was found to be 26%, with a predominance of papillary over follicular lesions. Rates were significantly higher in patients who had history of recent increase in swelling size and higher and higher pre-surgery TSH values.

This study examined the effect of alcohol(AL) and/or paraquat(PQ) on serum TSH, thyroid hormones and enzyme activities, and the protective effect of selenium(SE) againse alcohol and/or paraquat-induced thyroid toxicity in guinea pigs. The experomental group consisted of control, 15% alcohol(AL), 4ppm sodium selentite(SE), 200ppm paraquat(PQ), AL+PQ, AL+SE, PQ+SE and AL+PQ+SE mixed in drinking water-fed guinea pigs for 4 weeks. The morphological changes of thyroid gland were studies on paraffin-embedded sections stained with H-E stain. Body weight losses, high serum concentration in TSH and cholesterol, and low values on triiodothyronine($T_3$), thyrozine($T_4$), free $T_4$ and alkaline phosophatase(ALP) were produced in the groups fed AL and/or PQ. We also noted that AL+PQ-fed group was marked increase in serum TSH. In AL or AL+PQ-fed groups when cpmpared to control group had increased the ratio of thyroid weight to body weight(ratio Twt/Bwt), whereas the ratio Twt/Bwt was decresed in SE or PQ-fed groups. However, the serum TSH, $T_3$,$T_4$ free $T_4$ and cholesterol values, and the ratio Twt/Bwt were reversed in groups given the combination of SE, compared with AL and/or Pq-fed groups, also ALP values were reversed in groups given the combination of SE, compared with AL or AL+PQ-fed groups. In microscope, morphological changes showed a remarkable between the AL or PQ-fed group and controls. In AL+PQ+SE-fed guinca pig, follicular colloid is high density in thyroid follicle and increased in connective tissue around the thyroid cells, and thyroidal epithelia were composed of cuboidal or columnar epithelium. The indicated that the morphological changes of thyroid were direct action in the thyroid cell. The results of this study confirmed that the toxic effect of AL or PQ on thyroid occur independently of changes in liver function, and that SE confers marked protection against AL or PQ-induced thyroid toxicity.

Background and Objectives: Medullary thyroid carcinoma(MTC) is a rare tumor derived from the parafollicular C cells of the thyroid gland accounting for 5-10% of all thyroid malignancies. In Korea, there has been a few case report of medullary thyroid carcinoma(MTC) but their clinical analysis were not exactly studied. So, we made clinical study of 10 patients diagnosed as medullary thyroid carcinoma. Materials and Methods: We reviewed clinical data of 10 patients who were diagnosed as medullary thyroid carcinoma(MTC) from April 1973 to August 1998 at National Medical Center. Results: The incidence of MTC was 2.3% of all thyroid cancer and their mean age were 44.2 years old. Preoperative thyroid scan showed cold nodule in all patients and thyroid function test(TFT) was within normal range. Of the 10 patents, only 4 patients had diagnosis of MTC in preoperative fine needle aspiration biopsy. All the patients underwent total thyroidectomy with central neck dissection. Two patients with cervical lymph node metastasis underwent total thyroidectomy, central neck dissection and modified neck dissection. Two patients (20%) showed recurrence at the site of neck, lung, mediastinum, bone and liver. Conclusion: Most MTC is sporadic form and have peak incidence in the fifth decade and female preponderance. Preoperative fine needle aspiration biopsy is considered to be a clinically useful diagnostic method, but its accuracy is not considered as much high as others. Total thyroidectomy with central neck dissection may be an useful surgical modality in treating medullary thyroid carcinoma.

Objectives Thyroid hormone deficiency during the neurodevelopmental period can impair brain development and induce psychiatric symptoms. This study examined the association between thyroid dysfunction and the severity of symptoms in schizophrenia patients, and the treatment response of patients with schizophrenia. Methods Three hundred thirty-eight schizophrenia patients, with no prior history of thyroid disease or taking medication associated with it, were studied. We assessed the blood thyroid hormone level, the Brief Psychiatric Rating Scale (BPRS) scores on the day of admission and discharge, admission period, dose of administered antipsychotics, and the number of antipsychotic combinations. The collected data were subsequently analyzed using the Kruskal-Wallis test and Pearson's chi-square test. Results The percentage of schizophrenia patients who presented with abnormal thyroid hormone level was 24.6%. High total triiodothyronine (TT3) (p = 0.003), low TT3 (p = 0.001), and high free thyroxine (fT4) (p < 0.001) groups showed a higher BPRS score on admission than did the normal thyroid hormone group, while thyroid stimulating hormone (TSH) levels were not significantly correlated with the severity of symptoms. Furthermore, thyroid hormone was not associated with the treatment response assessed by the rate of BPRS score reduction, admission days, use of clozapine, and dose of antipsychotics. Conclusions The TT3 and fT4 hormone levels were significantly associated with the severity of symptoms in schizophrenia patients. These relations suggested that thyroid dysfunction may be associated with the severity of schizophrenia. And hence, further analysis of the results of the thyroid function test, which is commonly used in cases of psychiatric admission, is required.

The authors studied on the 5 cases of solitary thyroid nodule by T3 suppression test and TSH stimulation test. Radioiodine uptake and thyroid scan were observed after administration of dssicated thyroid and TSH. 3 of 5 cases were teated by $^{131}I$ and 2 by long-term adiministration of dessicated thyroid. Following were the results: 1. Nodular tissue was not affected by the administration of dessicated thyroid or TSH. 2. Extranodular tissue responded as normal thyroid tissue on the administration of dessicated thyroid or TSH. 3. There were many gradations from euthyroid to hyperthroid in clinical state. 4. Treatments were succesful in all cases except one case who was treated by long-term administration of dessicated thyroid.

Simultaneous occurrence of medullary and papillary thyroid carcinomas in the same gland is very rare. In fact. there are only 18 cases of simultaneous occurrence of medullary and papillary thyroid carcinomas in the literature. We report a case of simultaneous medullary and papillary carcinoma of thyroid gland. A 67-year-old woman was diagnosed with medullary carcinoma of right lobe of thyroid gland and papillary carcinoma of left lobe of thyroid gland by fine needle aspiration cytology. Total thyroidectomy, anterior neck dissection, bilateral modified radical neck dissection and tracheotomy was undertaken. The tumor metastasized to regional lymph node and extrathyroidal muscle invasion of left papillary carcinoma was also revealed by pathological report. This report describes a case of thyroid carcinoma that demonstrated both medullary carcinoma and papillary components in the thyroid with lymph node metastasis.

Anaplastic carcinoma of the thyroid (ACT) is a rare subtype of thyroid neoplasm. This tumor represents approximately 5-10% of all thyroid malignancies and has poor prognosis ACT often arises on a long-standing thyroid nodule and has been documented to be associated with a variety of more well-differentiated thyroid carcinomas. We experienced a case of anaplastic thyroid carcinoma who had had about a year history of thyroid getter. The patient had been injected with sclerosing agents in treatment of preexisting golfer. The ACT in this case had varied cytologic and histologic appearances: pleomorphic, giant cell, spindle and squamoid. Immunohistochemically, strong cytoplasmic positivity for cytokeratin was seen in all kinds of tumor cells. Ultrastructurally, the evidences of epithelial differentiation were seen such as intercellular junctions and tonofibrils.

BACKGROUND/OBJECTIVES: The incidence of thyroid cancer has increased in many countries, including Korea. International differences in the incidence of thyroid cancer may indicate a role of diet, but findings from previous studies are inconclusive. Therefore, we aimed to investigate the roles of nutrients in thyroid cancer risk in Korean women. SUBJECTS/METHODS: We conducted a case-control study comprising 113 cases and 226 age-matched controls. Nutrient intake was assessed using a validated food frequency questionnaire, and the association between nutrient intake and thyroid cancer risk was estimated using a logistic regression model. RESULTS: We found that high calcium intake was associated with a reduced risk of thyroid cancer (OR [95% CI] = 0.55 [0.35-0.89]). Significant associations were observed among subjects who were older than 50 years, had low BMI, and had low calorie intake. However, other nutrients included in this study did not show any significant associations with thyroid cancer risk. CONCLUSION: This study suggested a possible protective effect of calcium on thyroid cancer risk. Well-designed prospective studies are required to confirm these findings.
