Anti-thrombin III deficiency is known as a disease of autosomal dominant trait and relatively common, but in Korea, exact incidence and mortality is not known, In general, Anti-thrombin III deficiency is expressed to venous thromboembolism like deep vein thrombosis or pulmonary embolism. But, arterial embolism is very rare. We experienced a case of Antithrombin III deficiency expressed as myocardial infarction of inferior wall by huge thrombosis in the mid and distal right coronary artery.

BACKGROUND/AIMS: [18F]FDG-PET is a functional imaging modality reflecting cellular glucose metabolism. In most malignant cells, accumulation and trapping of [18F]FDG allows the visualization of increased uptake compared with normal cells. The aim of this study was to assess the value of PET in differentiating benign from malignant hepatic lesions and to determine in which types of hepatic tumors PET can help evaluate stage, monitor response to therapy, and detect recurrence. METHODS: Eighty patients with liver lesions were enrolled (hepatocellular carcinoma 34, cholangiocarcinoma 8, metastatic liver cancer 25, hemangioma 6, liver abscess 7). Liver metastases were 22 adenocarcinoma, 2 lymphoma, 2 squamous cell carcinoma. The PET images of these patients were analyzed. SUV and lesion-to-normal liver background SUV ratio were obtained and compared among the disease groups. RESULTS: All liver metastases and all cholangiocarcinomas had increased uptake value, with SUV ratios greater than 2. Hepatocellular carcinoma had SUV ratios greater than 2 in 20 of 34 patients (59%). All hemangiomas had poor uptake, a SUV ratio of less than 2. All liver abscesses showed definite uptake. CONCLUSIONS: The PET technique using FDG static imaging was useful in differentiating malignant from benign lesions of the liver in limited situations. Limitations included false negative results in some patients with hepatocellular carcinoma. Liver abscesses raised problems in differential diagnosis from malignant liver tumors. The findings of this study suggest that the PET technique might be applied in tumor staging and the detection of recurrence, as well as monitoring responses to therapy for all adenocarcinomas and some hepatocelluar carcinomas.

BACKGROUND/AIMS: The incidence of hepatocellular carcinoma has been universally lower in female than in male. The aims of our study are to define whether there are any difference between female and male patients with hepatocellular carcinoma in terms of clinical characteristics and results of treatment. METHODS: Retrospective analyses of medical history, physical findings, laboratory results, etiological factors, characteristics of tumor, and therapeutic results were performed in 80 female patients with hepatocellular carcinoma compared to 160 male patients. RESULTS: Asymptomatic presentation and family history of liver disease were found more frequently in female patients than in male patients. A history of smoking and alcohol drinking were found less frequently in female patients than in male patients. The detection rate of spider angioma was significantly lower in female patients than in male patients. There was no difference in laboratory results, characteristics of tumor, and therapeutic results between female and male patients. CONCLUSIONS: Environmental factors such as smoking and alcohol drinking could contribute the sexual difference of hepatocarcinogenesis. However, clinical characteristics at the time of diagnosis and therapeutic results were not significantly different between female and male patients with hepatocellular carcinoma.

Hereditary hemorrhagic telangiectasia(Osler-Rendu-Weber Syndrome) is characterized by telangiectasia of the skin and mucous membranes and intermittent bleeding from vascular abnormalities. About 20% of patients with this is syndrome have pulmonary arteriovenous fistulas. Pulmonary arteriovenous fistula is uncommon malformation which has an abnormal connection between the pulmonary capillary bed, in which venous blind in the pulmonary artery is shunted through the fistula into the pulmonary vein without exposure to alveolar oxygen and result in unoxygenated, desaturated systemic arterial blood, polycythemia, cyanosis and clubbing. Death often results from cerebral abscess and rupture of the malformation with massive hemorrhage. Therapeutic intervention is recommended for all symptomatic patients because of the risk of those serious complications. Treatment options include surgery and transcatheter obliteration with steel coils or detachable balloons. Therapeutic embolization has the advantages that multiple bilateral pulmonary arteriovenous fistulas can be occluded and also that the procedure can be repeated if necessary. Recently we experienced a case of the multiple bilateral pulmonary arteriovenous fistulas associated with telangiectatic change of hepatic artery and multiple angiodysplasia on the gastric mucosa in 41 years old female patient who had mild dyspnea of exertion(NYHA class II), clubbing finger, severe iron deficiency anemia. She was treated with embolization technique using steel coils and iron replacement. After the therapeutic embolization, significant improvement of dyspnea of exertion with disappearance of multiple pulmonary nodule on follow-up simple chest x-ray was noted. During the subsequent six months follow-up period, she bad the improvement of symptoms arid iron deficiency anemia.

Transcatheter arterial chemoembolization (TACE) is a therapeutic option for unresectable hepatocellular carcinoma. Supraumbilical skin rash is a rare complication of TACE caused by patent hepatic falciform artery. We report herein two cases of supraumbilical skin rash developed after TACE for hepatocellular carcinoma, with discussion on the pathogenesis, prophylaxis, and treatment.

BACKGROUND/AIMS: This study evaluated the prevalence and location of colonic adenomatous polyps in asymptomatic adults. METHODS: A total of 2,849 asymptomatic adults underwent colonscopic screening as a part of health evaluation from January 2003 to September 2005. Completed questionnaires as well as the colonoscopic and pathologic findings were analyzed. RESULTS: There were 406 (14.3%) subjects with adenomatous polyps including 78 (2.7%) with advanced polyps. There was a trend toward an increased prevalence of adenomatous polyps with age. The relative risk of a proximal polyp according to the distal findings was 5.7 (95% CI 4.3 ~ 7.4) for adenoma, 4.9 (95% CI 3.0 ~ 7.7) for advanced adenoma compared with that for no adenomatous polyp. There were no index polyps at the distal colon in 30% of the 406 subjects. CONCLUSIONS: Though distal polyps are associated with the proximal polyps, 30% of asymptomatic adults with proximal polyps are not associated with any distal index polyps. For those without any contraindication to the procedure, colonoscopy performed by experienced colonoscopists as a screening test is feasible for detecting those patients with colorectal polyps.
