We report a case of coronary fistula between the left anterior descending and main pulmonary artery complicating acute non-Q wave myocardial infarction. A 27-year-old man visited emergency department because of severe chest pain lasting two hours. The electrocardiogram showed ST segment elevation in precordial leads V3~6. Cardiac enzymes were as follows;CK-MB:36.44 IU/L T-T:0.489 ng/mL, CPK:542 IU/L, and LDH:475 IU/L. The thallium-201 dipyridamole stress perfusion scan showed perfusion defect and reversed redistribution in the anteroseptal wall. The coronary angiogram revealed coronary artery fistula between the proximal left anterior descending artery and main pulmonary artery without significant stenoses of coronary arteries. The result of ergonovine test was negative. After micro-coil embolization to the coronary fistula, symptoms were improved. Follow-up thallium-201 scan showed normalized blood flow in the left anteroseptal wall.

PURPOSE: Bacillus Calmette-Guerin (BCG) is known to suppress the asthmatic responses in a murine model of asthma and to induce dendritic cells (DCs) maturation. Mature DCs play a crucial role in the differentiation of regulatory T cells (Tregs), which are known to regulate allergic inflammatory responses. To investigate whether BCG regulates Tregs in a DCs-mediated manner, we analyzed in a murine model of asthma. METHODS: BALB/c mice were injected intraperitoneally with BCG or intravenously with BCG-stimulated DCs and then sensitized and challenged with ovalbumin (OVA). Mice were analysed for bronchial hyperresponsiveness (BHR), the influx of inflammatory cells in the bronchoalveolar lavage (BAL) fluid, and histopathological changes in the lung. To identify the mechanisms, IgE, IgG1 and IgG2a in the serum were analysed and the CD25+ Tregs in the mice were depleted with anti-CD25 monoclonal antibody (mAb). RESULTS: BCG and the transfer of BCG-stimulated DCs both suppressed all aspects of the asthmatic responses, namely, BHR, the production of total IgE and OVA-specific IgE and IgGs, and pulmonary eosinophilic inflammation. Anti-CD25mAb treatment reversed these effects. CONCLUSIONS: BCG can attenuate the allergic inflammation in a mouse model of asthma by a Tregs-related mechanism that is mediated by DCs.

Ischemic colitis generally develops in the elderly patients with concomitant cardiovascular condition, diabetes mellitus, and renal insufficiency. This disease predominently occurs in the left colon, particularly splenic flexure and sigmoid colon. The most frequent symptoms include abdominal pain, diarrhea, alteration in bowel functions and hematochezia. Blood loss is usually minimal in most patients. Herein, we report a case of ischemic colitis which developed on ascending colon with massive bleeding. A 48-year-old man was admitted because of massive lower gastrointestinal bleeding for 7 days. He has underwent hemodialysis for thirteen years. Colonoscopy showed a circular ulcer on the ascending colon with partial stenosis and mass-like oozing lesion distal to the stenotic area. We performed right hemi-colectomy. Grossly, colon showed shallow ulceration and congested ileocecal valve coated with hemorrhage. Microscopically, ulcer bed showed thickened and fibrotic submucosa which had nearly obliterated atherosclerotic vessels.

PURPOSE: To analyze the clinical results of treatment for infected total knee arthroplasty(TKA). MATERIALS AND METHODS: Between October 1993 and March 2003, 20 patients with infection after TKA were treated at our department. The average follow-up period was 3 years 8 months and the average age was 65.5 years(range, 50-79); there were 18 females and two men. Infected TKAs were managed with several methods ; 16 patients were treated two-stage reimplantation, 2 arthrodesis, and 2 debridement and polyethylene insert change. We assessed knee function before and after revision, according to the knee rating system of the Hospital for Special Surgery. RESULTS: Prior to revision operation, the average knee score in 16 reimplantation cases was 49.3 points and the average range of motion was 64.9 degrees. After revision, the average knee score was 80.5 points and the average range of motion was 90.3 degrees. Two of them relapsed within postoperative two weeks, and then we performed debridement. There was one recurrence of infection after debridement and polyethylene insert change and then we performed two stage reimplantation. Two patients had complete union at each 4, 5 months after arhtrodesis. CONCLUSION: Thoughtful method of treatment should be decided and precise operative technique should be performed in managing infected TKA.

OBJECTIVE: To evaluate the differences of mid-trimester triple marker levels in patients with mild versus severe and early versus late onset preeclampsia. METHODS: From January 2000 to December 2004, a retrospective study of 65 women with preeclampsia for whom mid-trimester triple test data were available was made. None of these patients had diabetes, other medical disorders, multiple pregnancy, abnormal karyotype and malformations. Preeclampsia patients were grouped to "early onset" [<32 weeks of gestation (wks), n=17] and "late onset" (n=48), and also "mild" (who had delivered with no symptoms and lab findings of severe preeclampsia at term spontaneous labor or elective cesarean delivery, n=31) and "severe" (n=34). The levels of mid-trimester maternal serum alpha-fetoprotein (MSAFP), human chorionic gonadotropin (hCG) and unconjugate estriol (MSuE3) in patients with early and late onset, mild and severe were compared. RESULTS: The each groups of comparison did not differ significantly with regard to age, weight, parity. The mean MSuE3 [0.92+/-0.09 (MoM+/-SE)] in patients with early onset was significantly lower than in patients with late onset preeclampsia (1.24 MoM, SE 0.07). In the comparison according to severity, the mean MSuE3 was significantly lower (0.98 MoM, SE 0.06 vs 1.28 MoM, SE 0.10, p=0.016) and the mean hCG was significantly higher (1.46 MoM, SE 0.12 vs 1.12 MoM, SE 0.07, p=0.015) in patients with severe preeclampsia than in those had mild preeclampsia symptoms at term delivery. CONCLUSION: Lower levels of mid-trimester MSuE3 and higher levels of hCG were associated with the severe preeclampsia rather than mild. Especially, lower levels of mid-trimester MSuE3 was also associated with early onset preeclampsia.

PURPOSE: Recognition of microbes is important to trigger the innate immune system. Mycolic acid (MA) is a component of the cell walls of mycobacteria such as Mycobacterium bovis Bacillus Calmette-Guerin. MA has immunogenic properties, which may modulate the innate and adaptive immune response. This study aimed to investigate whether a novel synthetic MA (sMA) inhibits allergic inflammatory responses in a mouse model of asthma. METHODS: BALB/c mice were injected intraperitoneally with sMA followed by sensitization and challenge with ovalbumin (OVA). Mice were examined for bronchial hyperresponsiveness (BHR), the influx of inflammatory cells into the lung tissues, histopathological changes in the lungs and CD4+CD25+Foxp3+ T cells in the spleen, and examined the response after the depleting regulatory T cells (Tregs) with an anti-CD25mAb. RESULTS: Treatment of mice with sMA suppressed the asthmatic response, including BHR, bronchoalveolar inflammation, and pulmonary eosinophilic inflammation. Anti-CD25mAb treatment abrogated the suppressive effects of sMA in this mouse model of asthma and totally depleted CD4+CD25+Foxp3+ T cells in the spleen. CONCLUSIONS: sMA attenuated allergic inflammation in a mouse model of asthma, which might be related with CD4+CD25+Foxp3+ T cell.

BACKGROUND/AIMS: It is suggested that patients consuming large amounts of alcohol are difficult to be sedated by midazolam probably due to cross tolerance. We studied to know the adequate administration doses of midazolam in patients with chronic alcohol consumption. METHODS: Study I; We prospectively studied 117 outpatients presenting for colonoscopy. According to alcohol consumption we divided four groups such as group I: 0 g/day, group II: <10 g/day, group III: 10~40 g/day, group IV: >40 g/day. We initially administered 0.06 mg/kg midazolam and add up to spontaneous eye closure. We measured grade of amnesia, level of consciousness, endoscopist's assessment and VAS scale for pain after recovery. Study II; We measured induction time after 0.08 mg/kg midazolam in 60 patients who drink alcohol. RESULTS: Additional amount of midazolam was not significantly different between the groups (group I: 0.0145 mg/ kg, group II: 0.0214 mg/kg, group III: 0.0181 mg/kg, group IV: 0.0199 mg/kg). There were no differences of sedation parameters between the groups. However the induction time was prolonged and correlated with alcohol consumption. CONCLUSIONS: For adequate sedation in patients with chronic alcohol consumption, longer induction time rather than increasing dosage is required.

Pelvic actinomycosis is a chronic granulomatous suppurative disease caused by an anaerobic gram- positive organism Actinomyces israelii. It is commonly associated with an intrauterine device(IUD) and can mimick pelvic or intra-abdominal malignant neoplasm. Ureteral obstruction leading to hydronephrosis is a rare complication of tubo-ovarian abscess. We experienced a case of hydronephrosis as a complication of pelvic actinomycotic abscess. The patient was a 46-year-old women presenting with fever and right flank pain. Leukocytosis and pyuria were present and a hydronephrosis was diagnosed by intravenous pyelography. Ultrasonography and a computerised tomography revealed a mass in right adnexum compressing the right ureter. Removal of retroperitoneal abscess and salphingo-oophorectomy were done and the diagnosis of actinomycosis was made by pathologic finding of resected mass. Postoperatively, the patient was treated with second-generation cephalosporin successfully.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major cause of chronic morbidity and mortality throughout the world and is the only major disease that is continuing to increase in both prevalence and mortality. The second Korean National Health and Nutrition Survey revealed that the prevalence of COPD in Korean subjects aged > or =45 years was 17.2% in 2001. Further surveys on the prevalence of COPD were not available until 2007. Here, we report the prevalence of spirometrically detected COPD in Korea, using data from the fourth Korean National Health and Nutrition Survey (KNHANES IV) which was conducted in 2007~2009. METHODS: Based on the Korean Statistical Office census that used nationwide stratified random sampling, 10,523 subjects aged > or =40 years underwent spirometry. Place of residence, levels of education, income, and smoking status, as well as other results from a COPD survey questionnaire were also assessed. RESULTS: The prevalence of COPD (defined as forced expiratory volume in 1 sec/forced vital capacity <0.7 in subjects aged > or =40 years) was 12.9% (men, 18.7%; women, 7.5%). In total, 96.5% of patients with COPD had mild-to-moderate disease; only 2.5% had been diagnosed by physicians, and only 1.7% had been treated. The independent risk factors for COPD were smoking, advanced age, and male gender. CONCLUSION: The prevalence of COPD was 12.9% in the KNHANES IV data. Most patients with COPD were undiagnosed and untreated. Based on these results, a strategy for early COPD intervention is warranted in high risk subjects.
