Osteoid osteoma, a frequent lesions of bone, is usually intraosseous but occasionally subperiosteal. We describe the case of a 19-year-old male with knee pain caused by subperiosteal osteoid osteoma. Radiologic evaluation was performed with radiographic, computed tomography (CT), ultrasonographic (US) and magnetic resonance imaging (MRI). But the preoperative diagnosis of osteoid osteoma was delayed because of unusual imaging findings and atypical symptom. After excisional biopsy, histological examination confirmed the diagnosis of osteoid osteoma. The lesion was treated successfully with CT-guided radiofrequency ablation.

The records of 255 cyanide poisoning deaths obtained from National Forensic Service (NFS) headquarters, located in Seoul of Korea, from 2005 to 2010 were retrospectively reviewed. The mean age was 41.88 +/- 13.09 and range was 6~80 years (unknown in seven cases). The number of deaths of males and females were 200 and 53, respectively (unknown in two cases). The largest number of cases occurred in people aged 40-49 years (81 cases, 31.8%), followed by the age groups 30~39 years (51 cases, 20%), 50~59 years (44 cases, 17.2%) and 20~29 years (43 cases, 16.9%). The total number of deaths among other age groups (below 10, 10~19, 60~69, 70~79, over 80 years and unknown) were 36, representing only 14.1%. Of all cyanide poisoning deaths, 97.3% were due to suicide, and 14.5% of the total number who died received medical treatment. The most frequent site for ingestion was the person's own residence (120 cases, 47.1%) and the route of administration was mainly oral (252, 98.8%). From the total of 255 cyanide poisoning cases, white powders were submitted for analysis in 92 cases. Potassium cyanide and sodium cyanide occupied 51 and 41 cases, respectively. This study showed that poisoning deaths due to cyanide are one of the continuously reported public health problems in Korea. Enforcement of regulations and safety education to prevent cyanide poisoning should be carried out by the government.

PURPOSE: The administration of 5-fluorouracil (5-FU) by protracted intravenous infusion is an alternative to the bolus administration of 5-FU in patients with advanced colorectal cancers. This study was performed to evaluate the response rate and toxicities of protracted infusion of 5-FU in patients with advanced or recurrent colorectal cancers who had been treated with 5-FU by bolus or shortterm continuous administration. MATERIALS AND METHODS: Between March 1995 and June 1997, twenty-eight patients with advanced colorectal cancer previously exposed to 5-FU based chemotherapy were enrolled in this triaL Patients received 5-FU (250 mg/m(2)/day days 1-28) or 5-FU plus leucovorin (5-FU; 200 mg/m/day days 1-28, leucovorin; 20 mg/m IV days 1, 8, 15, 21) by ambulatory infusion pump. Treatment course was repeated every 42 days until disease progression. RESULT: Twenty-eight patients entered. All 28 patients were assessable for response and toxicity. Five (19%) patients achieved a partial response, with the median response duration of 15 weeks (range; 7-22 weeks), and median survival time of entire patients was 54 weeks (range 7-151+ weeks). Gastrointestinal toxicity, specifically stomatitis was a major toxicity (grade 2, 12%; grade 3, 4%), but hand-foot syndrome was less frequent (5%) compared with other trials with protracted infusion of 5-FU reported in the literature. Hematologic toxicity was generally of low grade. CONCLUSION: Prolonged intravenous infusion of 5-FU can produce a response rate of 19% with low toxicity among patients refractory to bolus or short-term infusion of S-FU.

Ginsan, a botanic polysaccharide extracted from Panax ginseng, has recently been reported to modulate mucosal immune response. In this study, we investigated the protective effect of Ginsan against fatal Vibrio vulnificus mucosal infection. A lethal dose of V. vulnificus (1.0 x 106 CFU/mouse) was nasally inoculated to mice. The bacterial count in the nasal associated lymphoid tissue (NALT) of the mouse was significantly reduced in the Ginsan-treated group. The Ginsan-treated group showed improved survival compared to the control group (100% vs 18%). To elucidate the effect of Ginsan on modulating host immune response, cytokine mRNA expressions involved in mediating inflammation were determined by semiquantitative RT-PCR in the NALTs of the infected mice. Most of the cytokine mRNAs were similarly expressed as the control group. However, COX-1 mRNA expression level was higher in Ginsan-treated group compared to the control group. The protective effect of Ginsan was antagonized by treating with a specific COX-1 inhibitor, SC-560. Thus, these data suggest that the protective effect of Ginsan against V. vulnificus infection is partly mediated by modulating COX-1 expression.

We surveyed the generation rate of health statistics by medical records offices of the 78 hospitals and its automation rate using computerized hospital information system. Structured questionnaire was given to one medical record officer of each hospital. Items in the questionnaire was selected from statistics required for hospital service evaluation or OECD health statistics. More than 50% of the medical record office generated questioned health statistics, and most of them was automated. Because many of the medical record offices of the hospitals are producing essential health statistics and automated, there is a possibility that we can collect and use these datas to build up national health database if adequate standardization procedure can be implemented.

Enterotoxigenic Bacteroides fragilis (ETBF) is a human gut commensal bacteria that causes inflammatory diarrhea and colitis. ETBF also promotes colorectal tumorigenesis in the Min mouse model. The key virulence factor is a secreted metalloprotease called B. fragilis toxin (BFT). BFT induces E-cadherin cleavage, cell rounding, activation of the beta-catenin pathway and secretion of IL-8 in colonic epithelial cells. However, the precise mechanism by which these processes occur and how these processes are interrelated is still unclear. E-cadherin form homophilic interactions which tethers adjacent cells. Loss of E-cadherin results in detachment of adjacent cells. Prior studies have suggested that BFT induces IL-8 expression by inducing E-cadherin cleavage; cells that do not express E-cadherin do not secrete IL-8 in response to BFT. In the current study, we found that HT29/C1cells treated with dilute trypsin solution induced E-cadherin degradation and IL-8 secretion, consistent with the hypothesis that E-cadherin cleavage causes IL-8 secretion. However, physical damage to the cell monolayer did not induce IL-8 secretion. We also show that EDTA-mediated disruption of E-cadherin interactions without E-cadherin degradation was sufficient to induce IL-8 secretion. Finally, we determined that HT29/C1 cells treated with LiCl (beta-catenin activator) induced IL-8 secretion in a dose-dependent and time-dependent manner. Taken together, our results suggest that BFT induced IL-8 secretion may occur by the following process: E-cadherin cleavage, disruption of cellular interactions, activation of the beta-catenin pathway and IL-8 expression. However, we further propose that E-cadherin cleavage per se may not be required for BFT induced IL-8 secretion.

OBJECTIVE: To examine the effect of resveratrol on cell proliferation and cell cycle progression in the human uterine leiomyoma cells. METHODS: MTS [3-(4,5-dimethylthiazol-2-yl)5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium] reduction assay was carried out to determine the viability of human uterine leiomyoma cells. Western blot analysis was done using anti pRB, anti-p21cip1/waf1, anti-p53, anti-cyclin E, anti CDK2 antibodies to detect the presence and expression of these proteins in treatment with resveratrol. DNA fragmentation assay was done to find the rate of apoptosis. Cell cycle analysis for resveratrol treated in human uterine leiomyoma cells was done by FACS (fluorescence-activated cell sorter) analysis. RESULTS: Resveratrol induced growth inhibition in a dose dependent manner, treatment with 100 ?M/L resveratrol blocked 30% cell growth. From Western blot analysis it revealed resveratrol induced the expression of p53 increasing. Caspase pathway was activated and cleavage of PARP was occurred. Apoptosis took place but in a reduced manner. FACS results showed that resveratrol increased the percentage of cells in sub G1 phase. CONCLUSION: Resveratrol, a dietry phytoalexin, inhibited cell proliferation and induced cell cycle arrest at sub G1 by enhancing the production of p53. These results indicate that resveratrol will be a promising agent chemopreventives or therapeutics against human uterine leiomyoma cells.

BACKGROUND/AIMS: Colonic ischemia is recognized as the most common vascular disorder of the intestines in the elderly. The severity of the disease may vary considerably with the prevalent benign transient forms, being amenable to conservative treatments and the severe gangrenous forms, requiring surgery. Correct diagnosis is usually made after the ischemic episode is over and colonic ischemia is frequently misdiagnosed. The aim of this study is to identify the clinical patterns and prognostic factors of ischemic colitis. METHODS: We found 60 patients with nonoccusive ischemia of the large intestine. We analyzed age, sex, symptoms, signs, associated disease, location, endoscopy, hematologic, histologic, radiologic finding and treatment, retrospectively. RESULTS: The mean age was 60.2+/-16.3 years. The most common symtoms were abdominal pain or bloody diarrhea. The most common sign was diffuse abdominal tenderness. The most common hematologic findings were anemia and leukocytosis. Associated medical illnesses were diabetes, rhematoid arthritis and cerebrovascular accident, et al. Both computed tomography (CT) and endoscopy were useful diagnostic tools. The most common involved site was sigmoid colon. 46 patients were treated conservatively and 14 patients were managed surgically. CONCLUSIONS: Male gender, those with rebound tenderness, severe anemia, right or total colon involvement as well as rheumatoid arthritis had a poor prognosis. Both CT and endoscopy were useful in predicting prognosis.
