PURPOSE: To demonstrate and evaluate the value of MRI findings of the TSH(Thyroid-Stimulating Hormone, TSH, Thyrotropin)-secreting pituitary adenoma. MATERIALS AND METHODS: The authors reviewed retrospectively the MR images of 4 patients with TSH-secreting pituiatary adenoma. Evaluation of the anatomical location, signal characteristics, enhancement patterns, size, shape and circunferential changes were made. RESULTS: No characteristic common MR findings in size, shape, signal intensity, and circumferential changes of TSH-secreting pituiatary adenoma waere observed among 4 cases(size; 5x7 mm to 10x11 mm, shape;ovoid to round, signal intensity;high in 1 case on T1 and T2WI, isosignal intensity in the other 3 cases, circumferential change; stalk deviation in 1 case, no stalk deviation in 3 cases). But, the tumors were centrally located at the anterior pituitary gland and showed relatively homogeneous signal intensity on MR images of all 4 patients. CONCLUSION: We conclude that centrally-located mass at the anterior pituitary gland with homogeneous signal intensity on MR image may be suggestive of the TSH-secreting pituitary adenoma, although the MR findings are not specific for the disease.

The Finnish type of Congenital Nephrotic Syndrome is characterized by large placenta, early manifestation, growth and developmental delay and resistance to treatment. Authors experienced a case of characteristic Finnish type of Congenital Nephrotic Syndrome in a girl, who was admitted to the Pediatric Department of KHUH at 2 1/1 months of age because of generalized edema and abdominal distension and died of pneumonia at 5 1/2 months of age. The diagnosis was made by birth history, clinical manifestation, laboratory findings and finally by the autopsy findings, Literatures are reviewed briefly.

Authors report the first autopsy case of acquired immune deficiency syndrome in Korea. The patient was a 26 years old Korean male who died of respiratory failure due to mixed pulmonary infections. He had history of homosexual contacts with partners of both domestic and foreign nationalities. Initial presentation was unexplained fever for two months. Serological test and western blot test for anti-HIV were positive and T-cell subset analysis revealed T3/T4/T8 to be 73/8/67%. Pulmonary tuberculosis with mediastinal lymphadenopathy and esophagonadal fistula and oral candidiasis were presented. Respiratory infection progressed gradually and he died seven months after the initial symptom. Autopsy findings were generalized severe lymphoid cell depletion, especially of T-cell population and mixed pulmonary infections with Pneumocystis carinii and cytomegalovirus (CMV). The CMV infection involved lungs and adrenals. Oral candidiasis was also demonstrated.

Budd-Chiari syndrome is acute or subacute occlusion of the hepatic vein and IVC, The occlusion of hepatic veins often reveals dramatic illness characterized by abdominal pain, ascites, hepatomegaly and a poor prognosis. Several recent reports have suggested that balloon dilatation may be effective in Budd-Chiari syndrome. We experienced a case of Budd-Chiari syndrome with IVC web which was successfully treated with balloon dilatation. We report the case here with a brief review of literature,

PURPOSE: Through studying the clinical manifestation and prognosis of multiple colorectal cancer in comparison to those of solitary primary colorectal cancer, we expect this study to help establish a strategy for the diagnosis and treatment of it. METHODS: 2,302 patients with colorectal cancer, operated at the department of surgery, Yonsei university college of medicine, between Jan. 1989 and Dec. 1999 were evaluated for multiple colorectal cancer. Synchronous cancer was defined as distinct lesions separated by a distance of greater than 4 cm with the invasion of the tumor below the muscularis mucosa at the time of diagnosis. Metachronous cancer was defined as the development of colon cancer more than 6 months after the initial treatment without evidence of recurrence or metastasis from the primary tumor. RESULTS: The incidence of multiple cancer was 2.1% (49 patients). Among them, 1.8% were synchronous and 0.3% were metachronous. The average age was 59.7 years old, similar to the solitary colorectal cancer group whose mean age was 57.1 years old. The median follow up period was 44 months and average follow up period was 53 months. The frequency of cancer increased as it got closer to the rectum. The most frequent location was the rectum (43%) and the sigmoid colon (24%). The average time interval until the development of metachronous cancer was 46 months after initial operation. Adenomatous polyps were identified in 11 patients (43%) out of 49 patients with multiple colorectal cancer, whereas 538 patients (24%) out of 2,253 patients with solitary colorectal cancer were discovered with ademomatous polyps. The survival rate of multiple colorectal cancer was 59%, lower than that of solitary colorectal cancer (64%). But the difference was not statistically significant (P>0.05). CONCLUSIONS: The diagnosis of multiple colorectal cancer is very important in view of curative radical surgery and prognosis. This emphasizes the need for detection of early stage cancer by developing genetic markers and using advanced radiological diagnostic tools.

BACKGROUND: Excessive iodine intake increases the occurrence of autoimmune thyroid disorders by enhancing immunogenecity of iodine-rich thyroglobulin, In Korea, most of postpartum women take a large amount of iodine-rich seaweed. Although the excessive iodine intake may affect the thyroid function, only a few reports were available concering iodine intake, especially on postpartum period. METHODS: A prospective study was undertaken in 146 of normal delivered postpartum women. Dietary intake and urinary excretion of iodine, serum T3, T4, TSH, anti-TPO Ab and anti-Tg Ab were measured before and 1, 6, 12 and 24 weeks after delivery. Iodine intake was analyzed by one-to-one interview using 24hr recall and food frequency questionnaire. RESULTS: 1. PPT was occurred in 6 (10.3%) postparturn women, It presented as hypothyroidism alone in 1 (16.7%), transient thyrotoxicosis followed by hypothyroidisrn in 3 (50.0%), and thyrotoxicosis alone in 2 (33.3%) of the follwed-up patients. 2. During pregnancy, no difference was found in age, serum T3, T4 and TSH between PPT and normal thyroid function group. 3. In PPT group, anti-TPO and anti-Tg Ab were significantly higher than those of normal thyroid function group during pregnancy, and their sensitivity for PPT was 40% and 33%, respectively. But there was no correlation between dietary iodine intake and the titer of thyroid auto-antibodies. 4. There was no correlation between pre and post-partum dietary iodine intake and occurrence of PPT. CONCLUSION: In Korea, the incidence of PPT was slightly higher than other nations. The sensitivity of thyroid auto-antibodies was too low to use for prediction of PPT. Pre and post-partum iodine intake had no effect on the occurrence of PPT and post-partum thyroid function.

PURPOSE: Thallous-201 chloride produced at Korea Cancer Center Hospital(KCCH) is used in detecting cardiovascular disease and cancer. Thallium impurity can cause emesis, catharsis and nausea, so the presence of thallium and other metal impurities should be determined. According to USP and KP, their amounts must be less than 2 ppm in thallium and 5 ppm in total. In this study, the detection method of trace amounts of metal impurities in [201Tl]TlCl injection with polarography was optimized without environmental contamination. MATERALS AND METHODS: For the detection of metal impurities, Osteryoung Square Wave Stripping Voltammetry method was used in Bio-Analytical System (BAS) 50W polarograph. The voltammetry was composed of Dropping Mercury Electrode (DME) as a working electrode, Ag/AgCl as a reference electrode and Pt wire as a counter electrode. Square wave stripping method, which makes use of formation and deformation of amalgam, was adopted to determine the metal impurities, and pH 7 phosphate buffer was used as supporting electrolyte. RESULTS: T1, Cu and Pb in thallous-201 chloride solution were detected by scanning from 300 mV to -800 mV. Calibration curves were made by using TlNO3, CuSO4 and Pb(NO3)2 as standard solutions. Tl was confirmed at -450 mV peak potential and Cu at -50 mV. Less than 2 ppm of Tl and Cu was detected and Pb was not detected in KCCH-produced thallous-201 chloride injection. CONCLUSION: Detection limit of thallium and copper is approximately 50 ppb with this method. As a result of this experiment, thallium and other metal impurities in thallous-201 chloride injection, produced at Korea Cancer Center Hospital, are in the regulation of USP and KP. Polarograph could be applied for the determination of metal impurities in the quality control of radiopharmaceuticals conveniently without environmental contamination.
