PURPOSE: Recently, diagnosis of stage 1 gastric cancer has increased in number and prognosis is excellent when proper treatment is done. However, some patients have recurrence and their prognosis is poor. Thus, we investigated the risk factors of recurrence in stage 1 gastric cancer patients. METHODS: From January 2004 to December 2008, a total of 1,241 number patients were operated on for stage 1 gastric cancer at the Department of General Surgery, Kosin University Gospel Hospital. We reviewed the characteristics of all patients retrospectively and compared them to recurred group (n=24) and non-recurred group (n=1,114). We analyzed the risk factors associated with recurrence. RESULTS: Twenty-four patients with stage 1 gastric cancer were recurred after radical gastrectomy. Recurrence rate was 2.05%. The most common pattern of recurrence was hematogenous (41.7%), and lymphatic (20.8%), peritoneal seeding (16.7%), combined form (12.5%), and locoregional (8.3%). Five-year survival rate was 50.08% of recurrence group. Of clinicopathological factors, depth of invasion, lymph node metastasis, lymphatic involvement and tumor marker were statistically significant between recurred and other group. CONCLUSION: In this study, tumor marker, tumor depth, node status, lymphatic channel involvement were possible risk factors of recurrence for stage 1 gastric cancer. More intensive follow up and care is needed for those with such risk factors.

BACKGROUND AND OBJECTIVES: It is well known that anti-platlet agents decrease the rate of subacute thrombosis after intracoronary stenting significantly. The aim of this study is to assess the antithrombotic effect and safety of 2-month combined regimen of cilostazol and aspirin on intracoronary stenting. METHODS: The study population consisted of 78 lesions of 57 patients (age: 58.1+/-10.3, male 47, female 10) with ischemic heart disease who were underwent successful intracoronary stenting. They were received cilostazol(200mg/day) and aspirin(100mg/day) two days before intracoronary stenting and continued for 8 weeks, and then aspirin was medicated continuously during the study. The laboratory and clinical findings were evaluated before cilostazol administration, 4 weeks, 8 weeks and 6 months after intervention. The excercise treadmill test was done at 6 months after intervention. RESULTS: Subacute thrombosis occurred in 2 patients(3.5%). Target lesion revascularization(TLR) was done in 4 patients(7.3%). Clinical restenosis (symptomatic or positive stress test, subacute thrombosis and TLR) occurred in 15 patients(26.3%). There was no granulocytopenia, or severe liver dysfunction. HDL-cholesterol was increased significantly at 2 months(36.6+/-7.4 mg/dl versus 41.6+/-9.3 mg/dl. p<0.01) and 6 months(36.6+/-7.4 mg/dl versus 42.4+/-10.6 mg/dl. p<0.01) follow up. CONCLUSION: Two-month combined regimen of cilostazol and aspirin was effective and safe after intracoronary stenting. Subacute thrombosis and clinical restenosis rate were comparable with pervious reports. Further large randomized trials are needed for the evaluation of favorable effect of cilostazol on lipid metabolism.

BACKGROUND: The intimal thickening of coronary artery was understood as an early process in the beginning of atherosclerosis. However, the implication of intimal thickening as a morphologic change of coronary artery disease, on the coronary vascular hemodynamics has not been explored. METHODS: To evaluate the effect of intimal thickening on the coronary vascular hemodynamics, we studied the extent of intimal thickening on intravascular ultrasound(IVUS) and the coronary vascular flow and resistance by using Doppler wire in left anterior descending coronary arteries after successful intervention in 40 patients(29 males, mean age 55+/-9 years) with coronary artery disease. Mean intimal index and mean lumen cross sectional area were determined by IVUS and coronary flow average peak velocity was obtained by using Doppler wire before and after intracoronary adenosine in distal artery to the stenosis. Coronary flow velocity reserve(CFR), volumetric coronary blood flow(CBF) and coronary vascular resistance index(CVRI) were calculated. Hyperemic pressure-to-flow ratio(hyperemic mean aortic pressure/hyperemic volumetric coronary blood flow), ie, an index of minimal coronary vascular resistance(mCVR), was further derived. RESULTS: Intimal index(mean 20.0+/-8.3%) was significantly correlated with CVRI(mean 0.33+/-0.14, r=.37, p=.02) and mCVR(mean 0.81+/-0.40mmHg/ml/min, r=.36, p=.02). However, there was no correlation with CBF and CFR. CONCLUSION: The CVRI and mCVR(hyperemic pressure to flow ratio), the indices coronary microvascular resistance, were significantly related to the degree of intimal thickness of coronary artery. The extent of intimal thickness of coronary artery on IVUS study may be related to microvascular integrity.

BACKGROUND AND OBJECTIVES: Recent studies indicate that in response to vasoconstrictor stimuli, the small GTPase RhoA and its down-stream effector, Rho-associated kinase 2 (ROCK)/Rho-kinase, are associated with hypercontraction of the vascular smooth muscle of coronary arteries through augmentation of myosin light chain phosphorylation and Ca2+ sensitization. Expression of ROCK/Rho-kinase mRNA was significantly increased and up-regulated in the spastic coronary artery in a porcine model, and a specific inhibitor of ROCK/Rho-kinase inhibited coronary artery spasm in humans. We therefore explored the role of ROCK2 polymorphisms in the pathogenesis of vasospastic angina (VA). SUBJECTS AND METHODS: We studied 106 patients with VA who exhibited spontaneous or provoked coronary spasm during coronary angiography and compared the prevalence of ROCK2 polymorphisms between this group of patients with VA and controls whose angiograms were normal, and in whom the ergonovine test did not cause spasm (n=107). Five single nucleotide polymorphisms (SNPs) of the ROCK2 gene were selected. SNPs were genotyped by high-resolution melting. Linkage disequilibrium and haplotype analyses were performed using the SHEsis program. RESULTS: The prevalence of genotypes of the 5 interesting SNPs in patients with VA was not different from that in the control group. In haplotype analysis, the haplotype G-T-C-T-G (in order of rs978906, rs2271621, rs2230774, rs1515210, and rs3771106) was significantly associated with a decreased risk of VA (p=0.007). CONCLUSION: The haplotype G-T-C-T-G in the ROCK2 gene had a protective effect against VA, suggesting the involvement of ROCK2 in VA pathogenesis.

PURPOSE: To assess the clinical and radiological results of mobile bearing total knee arthroplasty using the LCS system and to analyse complications arising. MATERIALS AND METHODS: From Oct. 1992 to Dec. 1998, 135 cases of total knee arthroplasty was performed using the LCS mobile bearing system. Among those are evaluated 108 cases which were followed up for a mean of 4.8 years (3-9.2 years). Retrospective analysis was done by the clinical and radiological evaluations usinga ROM, tibio-femoral alignment, HSS score and radiological loosening. RESULTS: The preoperative mean HSS score (58.6) was improved to 89.5 at final follow up. Tibio-femoral angle changed from a varus of 3 degrees to a valgus of 5 degrees. Arc of motion was reduced from 121 degrees to 116 degrees in osteoarthritis and increased from 111 degrees to 118 degrees in rheumatoid arthritis. There were 16 cases of osteolysis, but no case provoked clinical problems or more than 4 points in the radiolucent score. Complications were one polyethylene dislocation and one intraoperative tibia plateau fracture. CONCLUSION: Mobile bearing knee system showed excellent and predictable clinical and radiological results at a mean 4.8 years follow-up.

Rhabdomyolysis varies from transient elevation of muscular enzyme to reduction of circulating volume and development of acute kidney injury (AKI). The majority is related to trauma, excessive exercise, alcohol and seizure disorders. Systemic infections associated with salmonellosis were rarely reported. Most of Salmonella infections are caused by Salmonella Typhi. Most common manifestations are typhoid fever and gastroenteritis. Sometimes serious complications such as gastrointestinal bleeding, intestinal perforation, and encephalopathy occur. However, AKI-associated rhabdomyolysis is rarely reported in salmonellosis even though it is not considered to be a major complication. Unfortunately, the precise pathogenetic mechanisms responsible for rhabdomyolysis with Salmonella Enteritidis infection are poorly understood due to the rarity of reported cases. In this presentation, we describe a patient with Salmonella Enteritidis (serogroup D) bacteremia complicated by disseminated intravascular coagulation, rhabdomyolysis and AKI. The blood culture and stool culture from the patient yielded Salmonella Enteritidis. Rhabdomyolysis and AKI should be considered as potentially fatal complications in patients with Salmonella Enteritidis infection.

OBJECTIVE: To examine the ability of published osteoporosis risk indices for prediction of osteoporosis in post- and perimenopausal women. METHODS: Subjects included 1559 of post- and perimenopausal women, 45 year old and older, recruited from Menopause Clinic from January 2002 to June 2004. Their bone mineral density (BMD) of femur neck was determined by dual energy x-ray absorptiometry (DXA), and their historical and clinical risk factors were assessed. We employed the World Health Organization (WHO) diagnostic criteria of osteoporosis for calculating the T scores, using race/ethnic and gender-specific young adult mean values. We applied 6 published osteoporosis risk indices (OSTA, ORAI, SCORE, SOFSURF, ABONE, NOF practice guideline) to each subject. Also, the predictive abilities of risk indices were assessed using the area under receiver operating characteristic (ROC) curve. RESULTS: The prevalence of osteoporosis and osteopenia was 8.7% and 32.6% for femur neck, 16.0% and 30.1% for lumbar spine, respectively. The prevalence of osteoporosis for femur neck was increased dramatically in the coming decades (1.6% for fifties, 8.7% for sixties, 43.0% for seventies, 64.1% for over eighties). ROC curve for predicting osteoporosis according to femur neck by OSTA showed the area under the curve (AUC) of 0.920. Sensitivity, specificity, and positive predictive value (PPV) were 93.4%, 75.4%, 26.6%, respectively. AUC for ORAI, SCORE, SOFSURF, ABONE, and NOF practice guideline was 0.896, 0.916, 0.871, 0.846, and 0.856, respectively. CONCLUSION: Validated risk indices have varying complexity, but similar sensitivity, specificity, and PPV for identifying individuals who are likely to have osteoporosis. However, OSTA is the most excellent risk index and simple tool.

OBJECTIVE: This study was performed to evaluate of correlation between ultrasonographic findings of endometrosis and endometriosis stage and recurrence. METHODS: We reviewed medical records of fifty-nine patients who admitted the department of Obstetrics and Gynecology of Sanggye Paik Hospital from April 1998 to June 2004 and were surgically confirmed endometriosis stage 3-4. GnRH agonist was injected every 4 weeks after the first injection following initial operation and a total of six doses were injected to a patient. We performed ultrasonographic examination of pre- and post-operation at an interval of 3 or 6 months. The endometriotic ultrasonographic findings were classified into three group; low-level internal echo (LIE), LIE and septation, LIE and hyperechoic wall foci. The correlation between ultrasonographic finding of endometrioma and endometriosis stage and recurrence were analyzed by Fisher's exact test and Pearson's chi-square test. RESULTS: The follow-up periods after operation were about 11.9 months. Typical ultrasonographic findings of endometrioma were observed on 50 of 59 patients, diagnostic performance of ultrasound in the detection of endometrioma had a 84.7% sensitivity in this study. In 50 cases, 48% (n=24) had a only low-level internal echoes, 32% (n=16) had a low-level internal echoes and multiple septation, 20% (n=10) had a low-level internal echoes and hyperechoic wall foci. The most common ultrasonographic findings were LIE (50%) in stage 3, LIE and septation (33.3%) in stage 4. During follow-up we observed ultrasonographic recurrence in 6 (10.2%) cases. There were no statistically significant correlation between ultrasonographic finding and endometriosis stage or recurrence. CONCLUSION: Ultrasound is a convenient and reliable method for diagnosis of endometrioma. But, it appears that ultrasonographic findings of endometrioma not correlate with endometriosis stage or recurrence. Further long term follow-up studies in large scale is needed for correlation between ultrasonographic findings of endometriosis and clinical significance.
