Pancreas lipomatosis is definde as fatty replacement of pancreatic acinar cells. Of the nine cases evaluated, seven cases (77.8%) of lipomatosis were limited inbody and tail, one case (11.1%) showed total lipomatosis excluding uncinate process and the remaining one case (11.1%) only in tail. As to the severity of lipomatosis, complete fat replacement in body and tail was found in four cases (44.4%), incomplete body and complete tail involvement in two (22.2%), incomplete body and tail, complete all except uncinate process, and complete tail involvements were found in one case (11.1%) each. Associated or predisposing factors included three diabetes mellitus (33.3%) combined with pancreas divisum, pancreas lithiasis and cholelithiasis respectively, hepatitis (22.2%) in two, and pseudocyst (11.1%) in one case, but in three cases (33.3%) nothing was found. In conclusion, pancreas lipomatosis was easily diagnosed by the abdominal CT and it was associated or predisposed by several e tities but had no major clinical symptoms, such as pancreatic insufficiency.

BACKGROUND: Cancer stem cells have been investigated as new targets for colorectal cancer (CRC) treatment. We recently reported that CD133+ colon cancer cells showed chemoresistance to 5-fluorouracil through increased survivin expression and proposed the survivin inhibitor YM155 as an effective therapy for colon cancer in an in vitro study. Here, we investigate the relationship between survivin and CD133 expression in surgically resected CRC to identify whether the results obtained in our in vitro study are applicable to clinical samples. METHODS: We performed immunohistochemical staining for survivin and CD133 in surgically resected tissue from 187 stage II or III CRC patients. We also comparatively analyzed apoptosis according to survivin and CD133 expression using terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling. RESULTS: The results of the Mantel-Haenszel test established a linear association between nuclear survivin and CD133 expression (p = .018), although neither had prognostic significance, according to immunohistochemical expression level. No correlation was found between survivin expression and the following pathological parameters: invasion depth, lymph node metastasis, or histologic differentiation (p > .05). The mean apoptotic index in survivin+ and CD133+ tumors was higher than that in negative tumors: 5.116 ± 4.894 in survivin+ versus 4.103 ± 3.691 in survivin– (p = .044); 5.165 ± 4.961 in CD133+ versus 4.231 ± 3.812 in CD133– (p = .034). CONCLUSIONS: As observed in our in vitro study, survivin expression is significantly related to CD133 expression. Survivin may be considered as a new therapeutic target for chemoresistant CRC.

Nineteen astrocytic neoplasms, such as 9 cases of glioblastoma multiforme, 6 cases of anaplastic astrocytoma and 4 cases of low grade astrocytoma, were analysed in view of the relationship between histopathologic grade, nuclear pleomorphism, grade of mutant p53 gene expression and mean survival time after operation. The histopathologic classification by Ringertz and immunohistochemical stain for mutant p53 gene with the DO-7 anti-p53 oncoprotein mouse monoclonal antibody were applied, and the results obtained were as follows; 1) Among 19 cases, 18 cases were located in the supratentorium, where 13 cases(42%) were located in the left and 17 cases(55%) in the right. 2) The p53 gene expression was detected in 12(63.2%) of the cases, as revealed by positive nuclear staining. All cases of glioblastoma multiforme showed p53 gene expression, compared with two(33.3%) cases of anaplastic astrocytoma and one(25%) case of low grade astrocytoma. The frequency and degree of histopathologic grade(p=0.03). 3) The mean survival time after operation was 29.49+/-4.08 months in cases with p53-negative tumors and 12.93+/-3.14 months in cases with p53-positive tumors(p<0.05). 4) Both histopathological classification and p53 gene expression showed a significant influence on servival(p=0.02 and p=0.03, respectively). 5) The relative risk for survival time was the highest in p53 gene expression. In conclusion, p53 gene expression appears to be one of the recommendable prognosticators among astrocytic neoplasms.

Thrombus-in-transit appears to increase the risk of mortality compared to pulmonary embolism alone and can require alteration in therapeutic plan. We present the case of a biatrial thromboembolus caught in transit across a patent foramen ovale diagnosed by intraoperative transesophageal echocardiogram in a 69-year-old female with acute pulmonary embolism and subsequent acute cerebral infarction. We suggest that echocardiography should be performed in a patient with suspected pulmonary thromboembolism to evaluate right heart function and diagnose emboli in transit.

The skin concentrations of 8-methoxypsoralen (8-MOP), 5-methoxypsoralen (5-MOP), and 4, 5', 8-trimethylpsoralen (TMP) were studied in the guinea pig following oral administration and bathing. The skin concentration of phototoxic drugs after oral administration peaked at 1.5 hours, and the concentration of 8-MOP was 3.5 times greater than that of 5-MOP. The skin concentration of TMP was not detected in our study (limit of sensitivity 5ng/ml). The skin concentrations of phototoxic drug after bathing decreased in the order of 5-MOP, TMP, and 8-MOP

OBJECTIVE: Recently, the prevalence of gall stone related with metabolic syndrome is increasing in Korea. The aim of this study was to reveal a relationship between components of metabolic syndrome and the development of gall bladder stones. METHODS: Among the subjects who visited a health promotion center of Soonchunhyang University Hospital from March 2009 to March 2010, a total of 5,201 adults were examined. Among them, the final 5,052 (male 3,403, female 1,649) adults were included. Sex, age, body mass index, waist circumference, blood pressure, fasting blood glucose, total cholesterol, triglyceride, high density lipoprotein-cholesterol levels, and the presence of gall stones were measured. Metabolic syndrome was defined by criteria of 2004 American Heart Association/Updated National Cholesterol Education Program Adult Treatment Panel III. Analyses were adjusted by age and sex. RESULTS: This study showed that the prevalence of gall stone was 1.6% and metabolic syndrome was 19.3%. The results didn't show an association between gall stone risk and components of metabolic syndrome. But gall stone risk was increased according to aging, high total cholesterol in the abnormal body mass index group. In normal body mass index group, waist circumference was related with the development of gall stone. Total cholesterol level was related with the development of gall stone in overweight group. CONCLUSION: This study showed total cholesterol levels and waist circumference related with prevalence of gall stone in specific body mass index group.

We describe a case of metastatic alveolar soft part sarcoma of the brain in a 31 year old women. Alveolar soft part sarcoma is rare tumor that occurs mostly in the extremities and have a high incidence of blood born metastasis. Cerebral metastasis may be the first manifestation of the disease. The histogenesis of alveolar soft part sarcoma remains uncertain. The primary therapeutic option is aggressive surgical excision. Survival even with the development of metasrasis can be long.

OBJECTIVE: To evaluate the reliability of virtual non-contrast (VNC) images reconstructed from contrast-enhanced, dual-energy scans compared with true non-contrast (TNC) images in the assessment of high CT attenuation or calcification of mediastinal lymph nodes. MATERIALS AND METHODS: A total of 112 mediastinal nodes from 45 patients who underwent non-contrast and dual-energy contrast-enhanced scans were analyzed. Node attenuation in TNC and VNC images was compared both objectively, using computed tomography (CT) attenuation, and subjectively, via visual scoring (0, attenuation < or = the aorta; 1, > the aorta; 2, calcification). The relationship among attenuation difference between TNC and VNC images, CT attenuation in TNC images, and net contrast enhancement (NCE) was analyzed. RESULTS: CT attenuation in TNC and VNC images showed moderate agreement (intraclass correlation coefficient, 0.612). The mean absolute difference was 7.8 +/- 7.6 Hounsfield unit (HU) (range, 0-36 HU), and the absolute difference was equal to or less than 10 HU in 65.2% of cases (73/112). Visual scores in TNC and VNC images showed fair agreement (kappa value, 0.335). Five of 16 nodes (31.3%) which showed score 1 (n = 15) or 2 (n = 1) in TNC images demonstrated score 1 in VNC images. The TNC-VNC attenuation difference showed a moderate positive correlation with CT attenuation in TNC images (partial correlation coefficient [PCC] adjusted by NCE: 0.455) and a weak negative correlation with NCE (PCC adjusted by CT attenuation in TNC: -0.245). CONCLUSION: VNC images may be useful in the evaluation of mediastinal lymph nodes by providing additional information of high CT attenuation of nodes, although it is underestimated compared with TNC images.

We report here on a rare case of papillary and follicular carcinoma of the thyroid gland that developed in a 31 years old woman who was previously diagnosed with Hashimoto's thyroiditis. Her chief complaint was a palpable neck mass. The antimicrosomal and antithyroglobulin antibody levels were elevated. Ultrasonography of the left thyroid gland revealed a 2.5x2.0 cm sized thyroid nodule. Fine needle aspiration biopsy of the thyroid nodule was done and this was diagnosed as Hashimoto's thyroiditis. There was no evidence of thyroid cancer. After 1 year, thyroid ultrasonography and biopsy were repeated for examining an enlarged thyroid nodule. Total thyroidectomy was then performed. The histopathologic examination revealed that the right and left thyroid glands were in accordance with the diagnosis of papillary and follicular cancer, respectively. Until now, no known case of simultaneous papillary and follicular carcinoma in Hashimoto's thyroiditis has been reported. This case suggests that adequate follow up for Hashimoto's thyroiditis patients with thyroid nodule may help the early detection and management of thyroid cancer.
