PURPOSE: To evaluate the extrahepatic spread of peripheral cholangiocarcinoma with CT. MATERIALS AND METHODS: We retrospectively reviewed CT findings of extrahepatic spread in thirty-six patients with peripheral cholangiocarcinoma confirmed adenocarcinoma at surgery(n=5) or percutaneous biopsy(n--31) without primary leion in other organs, and analysed the frequency and distribution of enlarged lymph nodes, direct invasion of adjacent solid organs, and thrombosis of major vessels. RESULTS: Among the 36 cases, enlarged metastatic lymph node was noted in twenty-four(66.7%), direct invasion into adjacent organs in six(16.7%), portal and inferior vena caval thrombosis in five(13.9%). Enlarged lymph nodes were seen in hepatic nodes(n=16, 44.4%), portocaval nodes(n=15, 41.7%), interaortocaval nodes (n=10, 27.8) and celiac nodes in two(5.6%). Direct invasion was detected in the greater omentum(n=6), gallbladder(n:3) and stomach(n=2). Portal vein thrombosis(n:5) and thrombosis of inferior vena cava(n=2) were noted. CONCLUSION: Lymph node metastasis was seen in 67% in patients with peripheral cholangiocarcinoma. Direct invasion to adjacent organs and thrombosis in portal vein or inferior vena cava were occasionally associated.

BACKGROUND: Dandruff is a common complaint, and is suffered by up to 50% of the population at some time. Malassezia yeasts, which comprise part of the normal skin flora, might be a critical factor in this disease, as they have been found in higher proportions in patients with seborrheic dermatitis or dandruff, its milder form. OBJECTIVE: The aim of this study was to evaluate the clinical efficacy of 4 weeks of treatment with 1% zinc pyrithione (ZP) shampoo. METHODS: A randomized, double-blind, 4-week treatment period was preceded by a 1-week run-in period. A total of 30 patients were enrolled in this study. Assessments included the patient's subjective score (PSS) and the investigator's assessment score (IAS), images of the affected scalp area, the severity of sebum production, and the erythema and moisturizing effect of the shampoo. RESULTS: 1% ZP shampoo significantly reduced the extent and severity of scaling, as measured by folliscope imaging on visit 2 (p=0.0391) and visit 3 (p=0.0381), as well as pruritus related to the disease as measured by the grading systems, PSS (p=0.0352) and IAS (p=0.0142). Additionally, the results of this study show that a treatment regimen with 1% ZP shampoo significantly reduced scalp sebum production as measured by a sebumeter. Erythema measured by the chromameter was not as meaningful. The corneometric values were slightly increased in the group treated with 1% ZP shampoo but not in the group treated with ZP-free shampoo. Side effects of the ZP shampoo were quite mild and tolerable, and were observed only in a small group of patients. CONCLUSION: 1% ZP shampoo appears to be both effective and well-tolerated when used for the treatment of dandruff.

The incidence of multiple primary cancers is low than that of single primary cancer. In gastric cancer, incidence of occurrence of multiple primary cancer is 3 to 11.3%. Because stomach and lung are unrelated organs, the combination of gastric cancer and lung cancer is rare. Its estimated incidence is about 10% of all multiple primary cancers. The histologic types of secondary lung cancer in one series, squamous cell carcinomas were 49%; adenocarcinomas were 28%; large cell carcinomas were 14%; small cell carcinomas were 9%; others were 6%. This patient had been diagnosed as early gastric cancer 3 years ago, but he refused operation for cancer and wasnt followed up. After 3 years, he revisited us for dry coughing and diagnosed as small cell lung cancer. At this time, previous gastric cancer was remained as well differentiated, early gastric adenocarcinoma. For its rarity, we report this case with review of literatures.

BACKGROUND AND OBJECTIVES: To determine the anatomic position of the inferior alveolar nerve (IAN) canal in patients with mandibular prognathism using the cone-beam CT (CBCT). MATERIALS AND METHODS: Fifty rami from 25 patients were evaluated. The images were taken by i-CAT and reconstructed 3-dimensionally using the Simplant 11 program. The linear distances between the IAN canal to the buccal cortex (a, a* and a**), from the IAN canal to the alveolar crest (b and b*) and the anterior margin (b**) and finally the buccal cortical thickness (c, c* and c**) were measured at three reference planes (VP, OP and HP). RESULTS: On the left side, the average distance of a, b and c were 7.12, 15.96 and 3.60 mm on the VP plane, respectively. On the OP, the distance of a*, b* and c* was 6.11, 8.83 and 2.63 mm. For the HP, the distance of a**, b** and c** was 4.84, 10.11 and 2.30 mm. On the right side, the distance of a, b and c, on the VP, was 7.10, 16.13 and 3.42 mm, respectively. On the OP, the distance of a*, b* and c* was 4.77, 8.75 and 2.68 mm. On the HP, the distance of a*, b* and c** was 4.55, 9.84 and 2.38 mm. Regarding the difference between genders, the distance in male's was longer than female's on the VP (p=0.019), and was thicker in males than females on the HP (p=0.002). CONCLUSION: The CBCT data provided accurate information about the location and course of the IAN.

BACKGROUND: Thus far, research studies on community-acquired pneumonia (CAP) have focused on its clinical severity. Recently, it has been determined that procalcitonin (PCT) level is correlated with severity of CAP. A retrospective study conducted at our hospital used risk predictability and PCT to determine whether or no PCT is useful in assessing the severity of CAP. METHODS: This study covered 92 CAP cases that were admitted to the respiratory department at Changwon Fatima Hospital between July 1, 2008 and June 30, 2009. All enrolled subjects were measured for infection markers and risk predictability. RESULTS: Based on hospital admission data, enrolled subjects had Pneumonia Severity Index (PSI) scores serving as risk predictors showed that both PCT and white blood cell (WBC) were statistically significant as infection markers (p=0.001, 0.037). Thus, this study used ROC curves in PSI for data analysis. As a result, it was determined that the area under curve (AUC) of PCT and WBC was 0.694 and 0.593 respectively, indicating that PCT has a higher test value for WBC, when PCT was higher than 0.745 ng/mL. In addition, it was found that PCT levels higher than 0.745 ng/mL had higher PSI scores than the group with PCT lower than 0.745 ng/mL (p=0.032). CONCLUSION: In order to predict risk of pneumonia cases admitted due to symptoms of CAP, it is important to consider PCT as well as PSI, and follow-up monitoring of PCT cases.

Bone morphogenetic proteins (BMPs) in combination with stem cells gain more significance for their use in bone tissue engineering. The mesenchymal stem cell can be differentiated into osteoblast by the treatment of BMP. The aim of this study is to characterize the osteogenic differentiation process of adult stem cells derived from buccal fat pad according to BMP-2 within culture media and decide the appropriate concentration of BMP-2 to facilitate osteogenesis. The authors procured the stem cell from buccal fat pad and analyzed for presence of stem cell by flow cytomety against CD-34, CD-105 and STRO-1. The buccal fat derived stem cells (BFDC) were treated by application of the different concentration with BMP-2 of 0, 10, 50, 100 and 200ng/ml, respectively. And their ability to differentiate into osteogenic pathway were checked by alkaline phosphatase(ALP) staining, Alizarin red staining and RT-PCR for osteocalcin(OC) gene expression at 7, 14 and 21day of culture. Flow cytometric analysis and biochemical assays demonstrated that BFDC might be a distinguished stem cells, and mineralization was accompanied in proportion to BMP-2 concentration. However, with 100ng/ml concentration of BMP-2, the BFDC demonstrated most efficent staining pattern of ALP and Alizarin red. The feasibilty of the osteogenic differentiation in the group of both 50ng/ml and 200ng/ml of BMP-2 showed similar activity and relatively weaker than that of 100ng/ml. These results suggest that the BMP-2 stimulate osteogenesis by BFDC effectively and that bone induction might be controlled through negative regulatory feedback in higher concentration.
