Hereditary hemorrhagic telangiectasia (HHT) or Osler-Weber-Rendu disease is an autosomal dominant disorder characterized by repeated episodes of bleeding. Multiple telangiectases consisting of thin-walled, dilated vascular channels with arteriovenous communication may involve, for example, mucocutaneous tissue, the gastrointestinal tract, and the liver, lung, and brain. We report the imaging findings of two cases of HHT involving arteriovenous malformation of both the lungs and liver, a rare condition. Chest radiography revealed a round mass, while helical CT showed a feeding artery and draining vein with arteriovenous malformation in the lung. Color Doppler sonography revealed an enlarged and tortuous hepatic artery with high systolic velocity. CT demonstrated an enlarged hepatic artery, arteriovenous shunt, and early draining hepatic vein in the liver. Celiac angiography showed arteriovenous malformation.

Cortex mori (Morus alba L.: Sangbaikpi), the root bark of mulberry tree, has been used as an antiphlogistic, diuretic, and expectorant in herbal medicine. Previous studies have demonstrated that the phenolic extract of Cortex mori have hypotensive, hypoglycemic, antifungal, antiviral, antiinflammatory, and anticancer effects, and the hot water extract from Cortex mori has inhibitory effects on compound 48/80- induced mast cell degranulation and histamine release from rat peritoneal mast cells (RPMCs). This study was perforrned to investigate the effects of polysaccharide fraction from Cortex mori (PFCM) on compound 48/80-induced degranulation, histamine release, calcium influx, changes of intracellular cAMP and cGMP level, and morphological changes of RPMCs. The results were summarized as follows. 1) Compound 48/80-induced cytomorphological changes such as swelling, degranulation, intracellular vacuoles, and interrupted cell boundary were significantly inhibited by pretreatment with either hot water or polysaccaride fractions frorn Cortex mori (PFCM), 2) the compound 48/80-induced histamine release from RPMCs pretreated with PFCM was significantly inhibited, compared to that of control without PFCM pretreatment, 3) the PFCM inhibited remarkably the compound 48/80-induced calcium influx into the RPMCs, 4) the PFCM increased significantly the intracellular cAMP levels and decreased the intracellular cGMP levels of RPMCs, compared to those of normal control, and 5) the compound 48/80-induced cAMP levels of RPMCs pretreated with PFCM were significantly increased, compared to those of positive control without PFCM, and the compound 48/80-induced cGMP levels of RPMCs pretreated with PFCM were remarkably decreased, compared to those of positive control without PFCM. From the above results, it is suggested that PFCM have an activity to inhibit the compound 48/80-induced mast cell activation.

Lipoma is one of the unusual benign breast neoplasms and usually manifests at fatty breast of women at the age of 40 to 60. We experienced a case of large breast lipoma nearly replacing the whole left breast parenchymal tissue with mammographic finding of well-defined radiolucent mass, sonographic finding of hyperechoic mass with disorganized echopattern and computerized tomographic finding of very low attenuation mass, characteristic to adipose tissue, in a young woman of her dense breast.

Pigmented villonodular synovitis(PVNS) is a synovial lesion of joints or tendon sheaths, characterized by villous and nodular overgrowth of the synovial membrane. It commonly occurs in synovial joints of the appendicular skeleton, particularly those of the knee and hip, but rarely affecting those of the spine. We report a case of PVNS of the lumbar spine mimicking epidural mass.

PURPOSE: To assess the efficacy of ancillary CT findings other than the obstructive lesion per se for the differential diagnosis of extrahepatic biliary obstruction. MATERIALS AND METHODS:CT findings of 49 patients with extrahepatic bile duct obstruction(22 benign and 27 malignant lesions) were assessed with emphasis on the patterns of ductal dilatation, contrast enhancement, and diffuse thickening of the extrahepatic ductal wall. Degree of central and peripheral intrahepratic ductal dilatation was graded by comparing with the adjacent portal radicles and hepatic parenchymal thickeness. RESULTS: Diffuse circumferential thickening and contrast enhancement of the extrahepatic ductal wall were more frequent in benign cases, but only thickening was statistically significant(p < 0.01). Peripheral intrahepatic ducts were more severely dilated by malignant causes(p < 0.01). With the same degrees of extrahepatic and central ductal dilatations, peripheral intrahepatic ducts were more severely dilated in malignant than in benign cases. CONCLUSION: These results may help to interpret the CT findings of extrahepatic biliary obstruction, particularly when the cause of biliary obstruction is uncertain.

We report a non-obese patient suffering from spastic gait and right leg paresis caused by thoracic spinal cord compression secondary to spinal epidural lipomatosis. Although spinal epidural lipomatosis is most often associated with the administration of exogenous steroid or endogenous Cushing syndrome, obesity also has been reported as a possible cause. However, idiopathic(non-glucocorticoid induced) spinal epidural lipomatosis in non-obese healthy man is an extremely rare disease and dose not have any good explanation for the abnormal fat deposition in spinal epidural space. We recently experienced a patient with idiopathic thoracic epidural lipomatosis in whom MRI and histopathology established the specific diagnosis. With a case report, brief review of the disease including clinical feature, diagnostic procedure and therapeutic considerations is described.

OBJECTIVES: To analyze differences in health behaviors among the social strata in Korea by using the 1995 National Health and Health Behavior Survey Data. METHODS: Study participants numbered 2,352 men and 1,016 women aged between 15-64 years old, with housewives, students and non-waged family workers excluded. Health behaviors in this study were defined according to the recommendations of the Alameda 7 study. The measure of health behaviors was based on the Health Practices Index(HPI; 0-5 range, with the exclusion of snacking between meals and regularly eating breakfast) developed by the Alameda County research. The significance of the relationship between social strata and HPI was assessed by considering the adjusted means from the multi-variate model. RESULTS: For men, incidence rates of never having smoked, no/moderate use of alcohol, regular exercise, and regular 7-8 hours sleep per night were higher in the upper social strata. Meanwhile, for women, incidence rates of never having smoked, no/moderate use of alcohol, appropriate weight, regular exercise, and regular 7-8 hours sleep per night were higher in the upper strata. HPI varied significantly among social strata in both sexes (p<0.001), a result which held true when adjusted for age, education, income, social insurance type, marital status and region. CONCLUSIONS: Health behaviors assessed by Health Practices Index(HPI) varied significantly among social strata for both sexes. Therefore, the existing gap in health behaviors among social strata can be corrected more effectively by target oriented health promotional activities.

BACKGROUND: Extended-spectrum cephalosporins and fluoroquinolones are important antimicrobials for treating invasive salmonellosis, and emerging resistance to these antimicrobials is of paramount concern. METHODS: A total of 30 Salmonella spp. clinical isolates recovered in Gyeongsangbuk-do from 2012 to 2013 were characterized using antibiotic resistance profiles and pulsed-field gel electrophoresis (PFGE). RESULTS: A high prevalence of multidrug-resistant isolates, mainly showing an ampicillin, nalidixic acid, chloramphenicol resistance pattern, was observed. Four extended-spectrum beta-lactamase (ESBL)-producing isolates (3 CTX-M-15 isolates and 1 CTX-M-27 isolate) were found. The bla(CTX-M-27) gene was carried by an IncF conjugative plasmid in the S. Infantis isolate. The bla(CTX-M-15) gene were carried by an IncF (2 isolates) or IncHI2 (1 isolate) conjugative plasmid in S. Enteritidis. In addition, a single mutation of GyrA, Ser83Thr (1 isolates), Asp87Tyr (9 isolates), Asp87Gly (4 isolates), and Asp87Leu (3 isolates), was detected in nalidixic acid-resistant Salmonella spp. isolates. XbaI PFGE analysis of all isolates revealed more than 19 different pulsotypes. The most common S. Enteritidis PFGE pattern (SEGX01.003) was associated with a larger number of cases of invasive salmonellosis than all other patterns. CONCLUSION: The information from our study can assist in source attribution, outbreak investigations, and tailoring of interventions to maximize disease prevention.
