Coronary artery ectasia (CAE) is a rare condition defined as the dilatation of coronary artery to at least 1.5 times larger than the normal adjacent coronary artery. Clinical manifestations of CAE vary, ranging from asymptomatic to ST-segment elevation myocardial infarction (STEMI). Because of its rarity and clinical diversity, the best treatment strategy and prognosis for CAE remain unclear. We describe a case of STEMI caused by intracoronary thrombus formation within an ectatic area in a patient with liver cirrhosis (LC). The patient was successfully managed by thrombus aspiration only, without balloon angioplasty or stent implantation, and maintained by dual antiplatelet therapy with aspirin and ticagrelor, a potent new P2Y12 inhibitor.

PURPOSE: The "Out-of-hospital Utstein Style" is an internationally recommended guideline for reporting outcome data for out-of-hospital resuscitation events. This study was designed to evaluate the current status of out-of-hospital cardiopulmonary resuscitation (CPR) in a tertiary emergency department and to provide basic data for a unified report on guidelines for resuscitation in Korea. METHODS: A clinical analysis of the out-of-hospital cardiac arrest (OHCA) patients, CPR performed in a tertiary emergency department, from July 1995 to December 2002 was conducted. The evaluation was made using Utstein reporting guidelines. RESULTS: Four hundred forty-nine patients were included in this study. The cardiac arrests were caused by non-cardiac medical diseases (41.9%), cardiac diseases (39.6%), unknown (10.0%), and trauma (8.5%). The initial electrocardiogram (ECG) showed asystole in 58.6% of the cases, other rhythms in 29.4%, and ventricular fibrillation/ventricular tachycardia (VF/VT) in 12.0%. Spontaneous circulation was restored (ROSC) in 41.2% of the cases. Twenty-four (5.3%) patients with witnessed and cardiogenic cardiac arrests had VF/VT on initial ECG, and of them, 5 (20.8%) patients were discharged alive. The mean circulatory arrest time was 19.7+/-13.6 minutes, and it was shorter in patients with ROSC (16.9+/-11.6) than in patients without ROSC (22.1+/-14.7, p= 0.003). CONCLUSION: The overall survival rate of OHCA patients was 6.7%, which was poorer than those of western countries. The overall duration from collapse to advanced cardiac life support (ACLS) was 19.7 minutes, which was too long. Major factors contributing to the low survival rate were most likely the lack of bystander CPR, delay in activating the emergency medical system (EMS), and inappropriate CPR by the EMT. We should make every effort to improve these areas.

Gastrointestinal stromal tumor (GIST) is a mesenchymal tumor derived from Cajal cells originating from the myotonic plexus. The expression of tyrosine kinase (KIT) membrane receptors that are active on KIT is inhibited by the KIT inhibitor imatinib mesylate. GISTs are resistant to conventional chemotherapy, and radiation therapy is not significantly beneficial for GISTs. With the development of imatinib mesylate, approximately 81.6% of patients with advanced and metastatic GIST exhibit an effect above the stabilization response, thereby increasing the survival time. However, imatinib mesylate alone is unlikely to cure metastatic GISTs. Even with a partial or stable response, imatinib mesylate may be used for a longer time period. However, resection of grossly visible lesions should be considered for patients with a stable response during surgical treatment. In this study, we present a case of GIST with liver metastasis after imatinib mesylate treatment, which was followed up without recurrence after partial resection.

OBJECTIVES: The aim of this study was to exam whether personality, i.e. temperament and character, has an association with a previous presence of psychotic features in euthymic bipolar I disorder. METHODS: We recruited 25 psychotic patients with bipolar I disorder, 23 non-psychotic bipolar I patients and 48 normal controls. All subjects were asked to perform Temperament and Character Inventory (TCI). Euthymic state was defined in bipolar patients by scores of below 10 on the Hamilton Depression Rating Scale (HDRS) and on the Young Manic Rating Scale (YMRS). RESULTS: Psychotic bipolar patients, compared to normal controls, showed higher harm avoidance (HA) and self-transcendence (ST). In addition, HA in psychotic bipolar patients was higher than that in non-psychotic bipolar patients. However, no significant differences on TCI were demonstrated between non-psychotic patients and normal controls. CONCLUSION: There are significant discrepancies in personality between psychotic and non-psychotic bipolar patients on HA and ST. These findings are consistent with the hypothesis of a continuum between bipolar disorder with psychotic features and psychotic disorders.

PURPOSE: TGF-beta-induced epithelial-mesenchymal transition (EMT) is associated with peritoneal fibrosis during PD. We conducted this study to evaluate the effect of BMP-7 adenoviral gene transfer on the functional and structural changes of peritoneum and whether it is associated with peritoneal EMT using an animal PD model. METHODS: Forty Sprague-Dawley rats were divided into five groups; Control (C, n=8), Dialysis (D, n= 8), Rest (R, n=8), BMP-7 (B, n=8) and LacZ (L, n=8) group. Peritoneal function was assessed on baseline, 3rd, 6th, 8th weeks after PD. Immunohistochemistry for TGF-beta, VEGF, laminin and aquaporin-1 was performed in addition to morphometric analysis of peritoneum. Immunofluorescence staining with western blotting for alpha-SMA and E-cadherin, as markers of EMT, was performed. RESULTS: The thickness of submesothelial matrix was highest in D and significantly decreased in B compared to D, R and L. D/D0 glucose at 8 weeks was significantly increased in B and L compared to that of at 6 weeks, but there were no significant differences among R, B and L at 8 weeks. TGF-beta1 and VEGF expression was observed in submesothelial matrix in D and decreased in R, B and L. Peritoneal fibrosis and functional deterioration of peritoneal membrane were associated with EMT, which was partially reversed in R, B and L. CONCLUSIONS: BMP-7 gene transfer to peritoneum was not associated with the additive therapeutic effect on peritoneal function compared to the peritoneal rest, although it improved morphologic changes of peritoneum.

PURPOSE: Transforming growth factor-beta1 (TGF-beta1) has been associated with the promotion of renal allograft interstitial fibrosis and thereby chronic allograft nephropathy (CAN). Vascular endothelial growth factor (VEGF) has been shown to contribute to cytoprotection of the graft after kidney transplantation. We investigated the influence of single nucleotide polymorphisms (SNPs) of the TGF-beta1 (C-509T and T869C) and the VEGF gene (C-2578A and C405G) on graft survival and the development of CAN. METHODS: Genotyping was carried out using a real-time polymerase chain reaction which was performed on the LightCycler480 in 221 Korean renal transplant recipients and 148 healthy controls. According to the presence of CAN or chronic calcineurin inhibitor nephrotoxicity, the recipients were separated into the CAN (n=21) and the No CAN (n=200) groups. RESULTS: The genotype frequencies of the SNPs were in Hardy-Weinberg equilibrium. The distributions of genotypes and alleles did not differ between recipients and controls. No significant differences were observed in the genotype distributions and allele frequencies between the CAN and the No CAN groups. The frequencies of haplotypes were not significantly different between the two groups, either. There were no statistically significant effects of TGF-beta1 and VEGF gene polymorphisms on graft survival. CONCLUSION: This study did not show any statistically significant effects of four selected SNPs of the TGF-beta1 and the VEGF genes on the development of CAN and graft survival in Korean renal transplant recipients.

PURPOSE: Tacrolimus (TAC) may be less unfavorable than cyclosporin A (CsA) on cardiovascular morbidity and mortality in renal transplant recipients, but well controlled studies are insufficient. METHODS: In this prospective randomized controlled study, fifty seven consecutive renal transplant recipients were treated with CsA-based (CsA, MMF and steroid, CsA group: n=27) or TAC-based (TAC, MMF and steroid, TAC group: n=30) immunosuppressive regimens by randomized ratio of 1:1. In the baseline (pre-operation), 1, 3, and 6 months after transplantation, several cardiovascular risk factors and graft function were evaluated. RESULTS: There were no significant differences in the renal function, glucose regulation, the incidence of acute rejection and post-transplant diabetes mellitus for the post-transplant 6 months between the two groups. The blood pressure of the CsA group was maintained higher than TAC group through 6 months after transplantation even though the number of antihypertensive drugs in the CsA group was significantly higher at 3 and 6 month after transplantation. The lipid profiles except oxidized LDL were similar, but oxidized LDL level was significantly higher for the post-transplant 6 months in the CsA group (p<0.05). There were no significant differences in levels of fibrinogen, PAI-I, t-PA, hs-CRP, homocysteine, spot urine TGF-beta a and beta ig-h3, but the uric acid level was significantly higher in the CsA group (p<0.05). CONCLUSION: This study demonstrates that TAC tends to have a beneficial effect on cardiovascular risk profiles, with regard to BP and atherogenic properties of serum lipids in early post-transplant period.
