Abstract
INTRODUCTION This study evaluated the efficacy and safety of a single-pill triple-combination of olmesartan/amlodipine/rosuvastatin (Olme/Amlo/Rosu) in comparison with a single-pill dual-combination of olmesartan/amlodipine (Olme/Amlo) in hypertensive patients with low-to-moderate cardiovascular risk. METHODS This multicenter, active-control, randomized study included 106 hypertensive patients at low-to-moderate cardiovascular risk who were randomly assigned to receive either Olme/Amlo/Rosu 20/5/5 mg (Treatment 1), Olme/Amlo/Rosu 20/5/10 mg (Treatment 2), or Amlo/Olme 20/5 mg (Control) once daily for 8 weeks. The primary endpoint was the difference of the percent change in low-density lipoprotein cholesterol (LDL-C) level at 8 weeks from baseline in the 3 groups. RESULTS The difference in the least square mean percent change (standard deviation) of LDL-C in the Treatment 1 and 2 groups compared with the Control group at 8 weeks was -32.6 (3.7) % and -45.9 (3.3) %, respectively (P < .001). The achievement rates of LDL-C level <100 mg/dL at 8 weeks were significantly different between the 3 groups (65.8%, 86.7%, and 6.3% for Treatment 1, 2, and Control groups, respectively, P < .001). The results of total cholesterol, triglycerides, high-density lipoprotein cholesterol, apolipoprotein B, and apolipoprotein B/apolipoprotein A1 were superior in the Treatment 1 and 2 groups compared with the Control group. Serious adverse drug reaction did not occur in the 3 groups. Medication adherence rates were excellent in the 3 groups (98.0% for Treatment 1 group, 99.7% for Treatment 2 group, and 96.3% for the Control group, P > .05). CONCLUSION Single-pill triple-combination of olmesartan/amlodipine/rosuvastatin was superior to the single-pill dual-combination of amlodipine/olmesartan in LDLC-lowering effects, with excellent safety profiles and adherence rates, in hypertensive patients at low-to-moderate cardiovascular risk.Trial Registration: CLinicalTrials.gov identifier NCT04120753.

Abstract
OBJECTIVE To evaluate the clinical outcomes of patients with severe acute respiratory distress syndrome (ARDS) subjected to prone positioning before extracorporeal membrane oxygenation (ECMO). DESIGN A retrospective analysis of a multicenter cohort was carried out. SETTING Patients admitted to the Intensive Care Units of 11 hospitals in Korea. PATIENTS Patients were divided into those who underwent prone positioning before ECMO (n=28) and those who did not (n=34). INTERVENTIONS None. VARIABLES OF INTEREST Thirty-day mortality, ECMO weaning failure rate, mechanical ventilation weaning success rate, mechanical ventilation-free days at day 60. RESULTS The prone group had lower median peak inspiratory pressure and lower median dynamic driving pressure before ECMO. Thirty-day mortality was 21% in the prone group and 41% in the non-prone group (p=0.098). The prone group also showed a lower ECMO weaning failure rate, and a higher mechanical ventilation weaning success rate and more mechanical ventilation-free days at day 60. In the non-prone group, median dynamic compliance marginally decreased shortly after ECMO, but no significant change was observed in the prone group. CONCLUSIONS Prone positioning before ECMO was not associated to increased mortality and tended to exert a protective effect.

Abstract
Invasive aspergillosis is an important cause of morbidity and mortality in patients who have undergone lung transplantation. Aspergillus infections usually involve the respiratory tract, with vascular invasion and subsequent dissemination. However, acute appendicitis associated with localized aspergillosis is rare, especially among patients who have undergone prophylaxis with voriconazole. We present a case of primary Aspergillus appendicitis diagnosed by histologic examination in a patient who underwent lung transplantation. A 51-year-old woman with dermatomyositis underwent lung transplantation for acute interstitial pneumonitis. According to our institution's protocol, the patient was treated with immunosuppressive therapy and prophylaxis with voriconazole, ganciclovir, and trimethoprim sulfamethoxazole during the post-transplantation period. Twenty-eight days after transplantation, the patient developed mild abdominal pain and paralytic ileus. There was no apparent infection sign. Abdominal computerized tomography indicated a wall defect of the appendix with multifocal fluid collection, mesenteric leave thickening, and pneumoperitoneum. These findings were consistent with perforated appendicitis, and the patient underwent an appendectomy. The histopathology examination of the resected appendix showed inflammation and abscess. Periodic acid-Schiff-positive and Grocott-Gomori methenamine silver-positive fungal hyphae with acute-angle branching were observed, demonstrating muscular invasion. A galactomannan antigen test obtained on the same day had negative results. The trough level of voriconazole was well maintained and was subsequently adjusted through monitoring of circulating drug concentration. Simultaneously, other potential sites of disseminated Aspergillus were considered and examined, but no other site of systemic Aspergillus infection was detected. Voriconazole treatment was maintained for 3 months, and no aspergillosis relapse or other invasive fungal infections were observed.

Abstract
BACKGROUND The Korean Organ Transplantation Registry (KOTRY) began to register lung transplants in 2015. This is an initial report on the status of patients receiving lung transplants over the past 2 years. METHODS We analyzed a total of 69 patients who received lung transplants in 2015 and 2016 and who registered with the KOTRY. RESULTS The 69 patients were treated in 5 institutions. The average (SD) donor age was 39.2 (12.6) years; there were 40 male patients. The average (SD) recipient age was 55.7 (10.0) years, and the number of male recipients was 46. A total of 66 patients underwent bilateral lung transplantation, 3 underwent single-lung transplantation, and 1 underwent simultaneous heart-lung transplantation. The most frequent indication for lung transplantation was idiopathic pulmonary fibrosis (35 patients), followed by connective tissue disease-related interstitial lung disease (9) and acute respiratory failure (8). Prior to transplantation, 23 patients required ventilator care, and 12 required extracorporeal membrane oxygenation while on the waiting list. Episodes of acute rejection during follow-up were reported in 4, 2, 1, and 1 patients at 3, 6, 9, and 12 months, respectively. Infections requiring hospitalization were reported in 27, 10, 4, and 3 patients at 3, 6, 9, and 12 months, respectively. CONCLUSION The establishment of KOTRY renders it possible to collect nationwide data on lung transplantation, improving research on the topic and clarifying clinical feasibility.

Abstract
BACKGROUND Extracorporeal membrane oxygenation (ECMO) is being used more often as a bridge to transplantation (BTT) in patients with acutely decompensated end-stage lung disease in Korea. ECMO as a BTT may be the only rescue strategy for severe acute respiratory failure, but many centers still consider it to be a relative contraindication to lung transplantation because of its poor outcome. Because there are not enough lung donors, it is important to determine their optimal use. We reviewed and analyzed our experiences with the use of ECMO as a BTT in patients with acute respiratory failure. METHODS This was a retrospective analysis of all patients with acutely decompensated end-stage lung disease treated with ECMO as a bridge to lung transplantation between March 2012 and February 2016. RESULTS Of the 194 patients who underwent respiratory ECMO over a 4-year period, a BTT strategy was used for 19 patients (median age, 58 years) on our institution's lung transplantation waiting list (15 veno-venous, 3 veno-veno-arterial, 1 veno-arterial). Fourteen patients (73.7%) were successfully bridged to transplantation; however, 3 died while on the waiting list and 2 returned to their baseline functions without transplantation. The overall in-hospital survival rate was 57.9% (11 of 19), including the 9 (64.3%) patients who underwent transplantation. CONCLUSIONS Our findings support the view that well-selected candidates with acutely decompensated end-stage lung disease may be safely bridged until a suitable donor is identified. ECMO is not able to reverse the course of patients; however, it could be a life-saving option for patients with acute respiratory failure requiring lung transplantation.

Abstract
BACKGROUND Kidney re-transplantation is commonly considered to have a higher immunological risk than first kidney transplantation. Because of the organ shortage and increasing waiting lists, long-term outcomes of kidney re-transplantation are being studied. However, reports of re-transplantation outcomes are not common. We have reported our 30 years of experience with second kidney transplantations. METHODS Of 1210 kidney transplantations between November 1982 and August 2016 performed in our hospital, 105 were second kidney transplantations (2nd KT). Living donor KT was 44; deceased donor KT was 61. RESULTS Patient survival rates at 1, 5, and 10 years were 100%, 97.2%, and 90.7%, and graft survival rates were 97.0%, 94.6%, and 71.5%, respectively. The leading cause of graft failure in the 2nd KT was chronic rejection (60%). In addition, induction immunosuppressant, maintenance immunosuppressant, delayed graft function, and graft survival time at the 1st KT had a significant impact on graft survival time at the 2nd KT. CONCLUSIONS Reasonable results in both patient survival and graft survival rates were found in the 2nd KT. Careful monitoring of immunologic risk is needed.

Abstract
The aim of this study was to evaluate nutritional care and outcomes in a medical intensive care unit (ICU) following multidisciplinary nutritional team (MNT) involvement. The authors retrospectively reviewed the data of all patients admitted to a medical ICU from April to October 2013 (pre-MNT period) and from April to October 2014 (post-MNT period). In total, 140 patients were included and allocated to the pre-MNT group (n=70) or the post-MNT group (n=70). The post-MNT group was more likely to use enteral nutrition (61.4 vs 37.1%, P=0.002). In terms of total calories and protein provided, the number of nutritional goal-achieved days during stays in ICU was significantly greater in the post-MNT group than in the pre-MNT group (63.7% vs 47.6%, P<0.05 and 44.3% vs 29.9%, respectively, P<0.05). The MNT activities resulted in significant improvements in terms of nutritional provision and adequacy in a medical ICU.

Abstract
The medical records of 38 pre-adolescent (aged ≤ 10 years) and 43 adolescent (aged 11-15 years) patients with primary osteosarcoma treated using the same protocol were reviewed in order to determine whether the clinical features and prognosis differed between these two groups. Gender, tumour location, tumour size, serum levels of alkaline phosphatase and lactic dehydrogenase before treatment, and chemotherapy-induced tumour necrosis were recorded, together with survival data. These parameters were compared in the two groups, and their prognostic significance was evaluated in the pre-adolescent patients. There were no statistically significant differences in the clinical parameters between pre-adolescent and adolescent patients. Only a poor level of chemotherapy-induced tumour necrosis was significantly associated with a poor prognosis in pre-adolescent patients. This study indicates that osteosarcoma behaviour is similar in pre-adolescent and adolescent patients, and there appears to be little justification for adopting different therapies in these two groups.

Abstract
Disseminated adenovirus infection in recipients of renal transplants is a rare but often fatal complication. We present a case of a 32-year-old woman who underwent renal transplantation from a deceased donor. Ten months after transplantation, she presented with dysuria, hematuria, and febrile illness. Despite the use of antibiotics, the patient's symptoms continued and worsened and the serum creatinine level was increased. The results of urine and serum polymerase chain reaction were positive for adenovirus. Renal biopsy revealed viral interstitial nephritis. The patient was treated with ribavirin, intravenous immunoglobulin, and reduction in immunosuppression. Her symptoms progressively improved from 7 days after the treatment. Serum and urine polymerase chain reaction for adenovirus became negative 10 and 21 days after the treatment, respectively. She remained in good health with excellent allograft function 6 months later.

Abstract
To date, it has been well documented that there is a relationship between alterations in thyroid hormones and cardiac dysfunction. We experienced a case of a 36-year-old man with dilated cardiomyopathy (DCM) accompanied by undiagnosed primary hypothyroidism. In the current case, there was a significant improvement in the cardiac function following heart failure management and thyroid hormone replacement. Our case highlights that clinicians should consider the possibility of hypothyroidism as a cause of DCM.

Abstract
Myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS) is a multisystem clinical syndrome manifested by mitochondrial myopathy, encephalopathy, lactic acidosis and recurrent stroke-like episodes. A 27-year-old female with MELAS syndrome presented with cerebral infarction. Echocardiography revealed a thrombus attached to the apex of the hypertrophied left ventricle, with decreased systolic function. The embolism of the intracardiac thrombus might have been the cause of stroke. There should be more consideration given to the increased possibility of intracardiac thrombus formation when a MELAS patient with cardiac involvement is encountered.

Abstract
BACKGROUND Cytomegalovirus (CMV) can cause morbidity in kidney transplant recipients. The gastrointestinal (GI) tract is a major target for CMV disease. The aim of this study was to evaluate the benefit of ganciclovir prophylaxis on GI CMV infection in intermediate-risk CMV seropositive transplant recipients. METHODS Since January 2009, intravenous ganciclovir (5 mg/kg, twice daily) was administered for 14 days after kidney transplantation in 41 patients. The historical control group consisted of 45 patients who received kidney transplantations between January 2007 and December 2008. To evaluate the effects of prophylaxis on GI CMV infection, we performed routine endoscopic examinations with mucosal biopsies at the time of transplantation as well as 1, 3, and 6 months thereafter. RESULTS The average age of the 86 studied patients was 43.7 ± 10.6 years (range = 14-63) and the male-to-female ratio 1:1.3. Forty-three (50%) patients underwent deceased donor transplantations and 84 (97.7%) patients were CMV seropositive at that time. The incidence of GI CMV infection was significantly lower among the prophylaxis than the historical control group (24.4% vs 48.9%, P = .026). Patient age, numbers of deceased donors, and tacrolimus trough levels at 1 and 3 months posttransplant were significantly lower in the prophylaxis than the historical control group. Logistic regression analysis revealed ganciclovir prophylaxis to be the only significant risk factor for GI CMV infection. CONCLUSION Prophylactic treatment with ganciclovir decreased the incidence GI CMV infection among seropositive kidney transplant recipients.

Abstract
Lysophosphatidylcholine (LPC) has been suggested to serve as a useful prognostic marker for sepsis. However, existing LPC assays are complicated, time-consuming, and of limited application in real clinical situations. Thus, we investigated the serum LPC levels in sepsis patients using an enzymatic assay and analyzed the correlations between the serum LPC concentration and clinical characteristics. We prospectively collected blood samples from suspected sepsis patients, commencing on day 1 of sepsis. We analyzed all samples using an enzymatic assay. Additionally, we analyzed the serum LPC concentrations in a control group of 21 healthy blood donors. A total of 105 patients who fulfilled the sepsis criteria were included. The mean serum LPC concentration was 43.49 ± 33.09 μmol/L in sepsis patients, which was much lower than that of 21 healthy controls (234.68 ± 30.33 μmol/L, p<0.001). Bacteremic sepsis was associated with a lower serum LPC concentration than non-bacteremic sepsis (34.8 ± 26.85 vs. 49.05 ± 35.63 μmol/L, p<0.05). No difference in serum LPC concentration was evident between survivors and non-survivors. The serum LPC concentration tended to decrease with the severity of sepsis. The day 1 serum LPC concentration was decreased in patients with sepsis, especially when bacteremia was present. However, the serum LPC level did not correlate with disease severity and did not predict mortality from sepsis.

Abstract
Percutaneous coronary intervention of chronic total occlusion (CTO) is one of the greatest challenges in coronary interventions. Retrograde wiring is suggested as a solution to improve the success rate of intervention for CTO. We experienced the coronary perforation during antegrade wiring at the CTO lesion and sealed it using retrograde wiring and antegrade stenting in a patient who underwent coronary arterial bypass grafting. We found that, in selected cases, the retrograde wire technique may provide a valuable rescue option for perforated CTO in a patient having a retrogradely accessible conduit vessel.

Abstract
BACKGROUND In this retrospective study, we developed and internally validate a nomogram for predicting 5-year metastasis probability for nonmetastatic extremity osteosarcoma. PATIENTS AND METHODS We reviewed 365 osteosarcoma patients treated at our institute from 1990 to 2003. Clinicopathologic variables were recorded. Multivariate analysis using Cox proportional hazards regression was done and this Cox model was used as the basis for the nomogram. RESULTS By American Joint Committee on Cancer (AJCC) staging system, 141 patients (38.6%) were stage IIA and 224 (61.4%) were stage IIB. Multivariate Cox model identified patient age at diagnosis, tumor size, humeral location, and tumor necrosis rate after chemotherapy as correlated with metastasis-free survival. The degree of contribution of each covariate to the total point was tumor location, tumor necrosis rate, maximal tumor diameter, and age in decreasing order. The concordance index for the model was 0.78. Nomogram discrimination was superior to that of AJCC stage (concordance index 0.78 versus 0.68; P = 0.02) and histologic response grouping (concordance index 0.78 versus 0.69; P = 0.0004). CONCLUSIONS We devised a nomogram for nonmetastatic osteosarcoma that proposes improved estimates of metastasis over AJCC staging system or tumor necrosis rate. We suggest that this nomogram allows individualized risk assessments and could be used as the basis for risk-adapted therapy.

Abstract
Viruses are the most common cause of opportunistic infections, important complications of transplantation. Mumps infection in renal transplant recipients is uncommon. This report focused on a 23-year-old woman who received immunosuppressive therapy based on tacrolimus, prednisolone, and mycophenolate mofetil for renal transplantation. Sixteen months after transplantation, she was admitted with pain and swelling in both infra-auricular areas. Laboratory findings demonstrated positive mumps IgM and IgG antibodies and an increased serum amylase level. Computed tomography revealed both parotid glands to be diffusely enlarged. After the diagnosis of mumps parotitis, the patient's immunosuppression was reduced and the clinical course was satisfactory.

Abstract
The authors report the case of multiple right-sided myxomas in a 42-year-old man with Carney complex. He had previously been diagnosed as Cushing's syndrome and undergone resection of pituitary adenoma at the age of 21. After 10 years, bilateral adrenalectomy had been performed with recurrence of Cushing's syndrome. Recently, he complained of palpitation and intracardiac masses were detected. On physical examination, he had nevi on the lips and in the oral cavity. A tiny eyelid nodule was noted and histopathological analysis confirmed the diagnosis of skin myxoma. Thyroid ultrasonography revealed multiple hypoechoic nodules, which were confirmed pathologically as follicular adenomas. Scrotal ultrasonography also revealed small multiple testicular tumors. Echocardiography demonstrated intracardiac masses in right atrium and right ventricle. Right atriotomy revealed a right atrial mass attached to the annulus of the tricuspid valve and another mass arising from the interatrial septum. In right ventricle, a polypoid mass arose from the anterior leaflet of the tricuspid valve. Also, there were multiple tiny to small masses on the interatrial septum. The masses were completely excised and the tricuspid valve was repaired with annuloplasty. Histopathological analysis confirmed myxomas with foci of extramedullary hematopoiesis and ossification.

Abstract
Intimal hyperplasia is the leading cause of late vein graft failure. Smooth muscle cell proliferation and migration is the underlying mechanism. Pharmacological approaches to prolong vein graft patency have produced limited results. AP-1 proteins play a role in the expression of many genes involved in cellular proliferation and cell cycle progression. Previously we reported inhibition of vascular smooth muscle cell migration, proliferation, and intimal hyperplasia in the balloon-injured rat carotid artery using an AP-1 decoy with HVJ-liposomes. In this report, we evaluated the effect of the AP-1 decoy on intimal hyperplasia in a large animal model. The jugular vein was transfected with hemagglutinating virus of Japan-liposomes containing the AP-1 decoy or scrambled oligonucleotides. An interposition graft was performed with the pretreated jugular vein between the transected femoral arteries. The graft was harvested at 16 weeks after the procedure. The intimal area was compared: the intimal area of the AP-1 decoy-treated versus control group was 47.3 +/- 15.2 versus 102.3 +/- 15.9 (P < .05), respectively. In conclusion, AP-1 decoy using HVJ-liposomes effectively prevented intimal hyperplasia of an autogenous vein graft in mongrel dogs.

Abstract
INTRODUCTION Cytomegalovirus (CMV) and polyoma virus BK (BKV) may both establish latency following primary infection. Frequent reactivation of these viruses can occur in the kidney transplant recipients. BKV may induce CMV gene expression by stimulating cellular regulator proteins or by its own gene regulator proteins. A high rate of concurrent CMV infections has been noted in kidney transplant recipients with polyoma virus-associated nephropathy (PVAN). METHODS PVAN was identified in 10 of 191 patients who received kidney transplants between October 1998 and September 2003. PVAN was confirmed by allograft kidney biopsy. Four of the 10 patients were complicated by concurrent CMV infection. RESULTS Two patients had only serological evidence of CMV infection and one patient had CMV gastritis. These three patients were treated with intravenous ganciclovir with good results. Disseminated ganciclovir-resistant CMV disease was demonstrated in the remaining patient. This 34-year-old kidney transplant recipient with PVAN died of multiorgan failure despite antiviral therapy with both ganciclovir and foscarnet. CONCLUSION PVAN with concurrent CMV infection in kidney transplant recipients showed variable clinical courses including mortality. Further studies are needed to elucidate the influence of PVAN on the pathogenesis of CMV infection.

Abstract
PURPOSE To examine the imaging characteristics of osteoblastic osteosarcoma in older patients, we compared them with those in adolescents because the radiological features of osteosarcoma can be atypical in elderly patients. MATERIAL AND METHODS 29 cases of adolescent patients and 12 patients older than 40 years of age were reviewed. All cases were pathologically confirmed as osteoblastic osteosarcoma. The comparative factors were tumor location, plain radiological features including periosteal reactions, and the degree of soft tissue mass with magnetic resonance (MR) imaging. RESULTS Older patients demonstrated frequent osteolytic findings (83.3%), and none of the tumors showed a significant major periosteal reaction. Seven (58.3%) of the 12 tumors had no soft tissue mass (grade 0) and only three (25%) had a grade 3 mass. The differences in the two groups were statistically significant (P<0.001). CONCLUSION In older patients, primary osteosarcoma should be considered when making a differential diagnosis of osteolytic lesions without any periosteal reactions and small soft-tissue extensions. In cases with atypical findings, the morphology of specimens (aspiration, core, or surgical biopsy) from the lesion should be recommended when making an accurate diagnosis.

Abstract
15-Deoxy-(Delta12,14)-prostaglandin J(2) (15d-PGJ(2)) is a naturally occurring cyclopentenone metabolite of prostaglandin D(2) (PGD(2)) and is known as a specific potent ligand for the peroxisome proliferators activator receptor-gamma (PPARgamma). 15d-PGJ(2) inhibits cell growth and induces apoptosis in a number of different cancer cells. However, the underlying mechanism by which 15d-PGJ(2) induces cell death remains to be defined. The present study was undertaken to determine the effect of 15d-PGJ(2) on cell death in A172 human glioma cells. 15d-PGJ(2) caused reactive oxygen species (ROS) generation. 15d-PGJ(2)-induced ROS production and cell death were prevented by the antioxidant N-acetylcysteine. Activation of mitogen-activated protein kinases (MAPK) was not observed in cells treated with 15d-PGJ(2 )and inhibitors of MAPK subfamilies also were not effective in preventing 15d-PGJ(2)-induced cell death. 15d-PGJ(2) treatment caused mitochondrial dysfunction, as evidenced by depolarization of mitochondrial membrane potential. 15d-PGJ(2) induced caspase activation at 24 h of treatment, but the 15d-PGJ(2)-induced cell death was not prevented by caspase inhibitors. The antiapoptotic protein XIAP levels and release of apoptosis inducing factor (AIF) into the cytosol were not altered by 15d-PGJ(2) treatment. Taken together, these findings indicate that 15d-PGJ(2) triggers cell death through a caspase-independent mechanism and ROS production and disruption of mitochondrial membrane potential play an important role in the 15d-PGJ(2)-induced cell death in A172 human glioma cells.

Abstract
Distal anterior inferior cerebellar artery (AICA) aneurysms are rare and most cases have been treated surgically by clipping, wrapping or trapping. We recently treated this 20-year-old male patient by an endovascular technique. At first, he was treated by intra-aneurysmal embolisation with parent artery preservation. But he presented with rerupture 1 month after embolisation. Follow-up angiography revealed the regrowth of the aneurysm, which was considered as a dissecting aneurysm. We performed occlusion of the AICA just proximal to the aneurysm to prevent fatal rebleeding. He gradually improved and his level of consciousness fully recovered. At 2 year follow up, he had no neurological deficits. We suggest that embolisation of distal AICA aneurysm with parent artery occlusion may be safe and a simple method in the treatment of distal AICA aneurysms.

Abstract
Double-stranded DNA with high affinity to E2F as a decoy cis-element blocks the activation of genes mediating the cell cycle, resulting in effective suppression of the smooth muscle cell proliferation that causes intimal hyperplasia. To evaluate the effect of the E2F decoy to suppress neointimal hyperplasia autogenous venous bypass grafts were performed in dogs after incubation with heparin (group 1), with E2F decoy oligodeoxynucleotides (ODN) (groups 2 and 3), or with a random ODN (group 4) using a Japan-liposomeal method based on a hemagglutinating virus. The intimal and medial cross-sectional surface area of the anastomotic site was measured at 4 months after bypass surgery in groups 1, 3, and 4 by computerized planimetry and at 4 weeks in group 2 to compare the intimal/medial (I/M) area ratios. Autogenous vein grafts treated with E2F decoy showed a significant reduction in I/M area ratio (0.26 +/- 0.11) compared with the heparin-treated control group (1.49 +/- 0.29) or the mismatched ODN-treated group (1.61 +/- 0.28; P = .000). There was no difference in the I/M area ratio according to experimental periods (groups 2 vs 3: 0.26 +/- 0.11 vs 0.37 +/- 0.32; P = .446) or the anastomotic sites (proximal vs distal; P = .934). In conclusion, an E2F decoy can suppress neointimal hyperplasia in autogenous vein grafts, which may prolong patency by reducing graft stenosis.

Abstract
Swallowing is a rare cause of neurally mediated syncope. The mechanism of swallow syncope that contributes to hypotension, bradycardia, or to both is complex. A 59-year-old man had experienced a recurrent loss of consciousness during swallowing of carbonated beverages or sticky foods. Another 59-year-old man had complained of intermittent syncope just after eating foods. These two patients had no significant structural or functional abnormalities in the esophagus or heart. Both cases showed bradycardia when the lower esophagus was stretched by balloon inflation. The activation of mechanoreceptors in the lower esophagus can be regarded as an initiating factor of these cardioinhibitions. The patients were treated with permanent pacemaker implantation and instructed to change eating habits, respectively.

Abstract
INTRODUCTION The 1-year results of the phase III US Multicenter Trial comparing tacrolimus- and cyclosporine (Sandimmun)-based immunosuppressive therapy in kidney transplantation revealed a significant reduction in the incidence and severity of acute rejection episodes among patients maintained on tacrolimus. This retrospective, nonrandomized, single-center study represented 3-year data for patient and graft survival and safety in the tacrolimus-treated patients. METHODS Among 97 consecutive kidney transplant recipients 41 who received tacrolimus and 56 cyclosporine-based immunosuppression were followed for 3 years for patient and graft survivals and for the incidence of acute rejection episodes as well as serious adverse events. RESULTS The 3-year patient and graft survival rates for tacrolimus and cyclosporine were similar (91.0% vs 90.2%, 96.5% vs 95.0%). However, the incidence of acute rejection episodes was significantly lower in the tacrolimus (17.1%) compared with the cyclosporine group (35.7%, P = .043). There was a higher incidence of headache, posttransplant diabetes, and alopecia reported in the tacrolimus group, whereas hypertension, hypercholesterolemia, and hirsutism were more frequent in the cyclosporine group. The incidences of hand tremor, hyperkalemia, and viral infections were comparable in both groups. Two patients in the tacrolimus group were converted to cyclosporine due to nephrotoxicity and posttransplant diabetes, respectively, whereas 12 patients in the cyclosporine group were converted to tacrolimus as rescue therapy for acute rejection (41.7%), gingival hyperplasia (33.3%), nephrotoxicity (8.3%), neurotoxicity (8.3%), and hirsutism (8.3%), respectively. CONCLUSION The 3-year results of tacrolimus treatment show excellent efficacy and safety in kidney transplantation. Due to different side-effect profiles, it is necessary to develop individualized immunosuppressive strategies in kidney transplant recipients.

Abstract
We document the MRI features in six patients aged 5-14 years with acute encephalitis following measles. The diagnosis was made on a characteristic morbiliform rash and detection of specific IgM and IgG antibodies. The symptoms of encephalitis occurred 1-11 days after the appearance of the rash. All patients underwent MRI within 1-4 days of the onset of neurological symptoms. Diffusion weighted images (DWI) were obtained in three patients. In all patients, T2-weighted images showed widely distributed, multifocal high signal in both cerebral hemispheres with swelling of the cortex, with bilateral, symmetrical involvement of the putamen and caudate nucleus. The lesions had showed low apparent diffusion coefficients. Three patients showed subacute gyriform haemorrhage, and asymmetrical gyriform contrast enhancement on follow-up MRI.

Abstract
In 16 mature New Zealand white rabbits mesenchymal stem cells were aspirated from the bone marrow, cultured in monolayer and implanted on to a full-thickness osteochondral defect artificially made on the patellar groove of the same rabbit. A further 13 rabbits served as a control group. The rabbits were killed after 14 weeks. Healing of the defect was investigated histologically using haematoxylin and eosin and Safranin-O staining and with immunohistochemical staining for type-II collagen. We also used a reverse transcription-polymerase chain reaction (RT-PCR) to detect mRNA of type-I and type-II collagen. The semiquantitative histological scores were significantly higher in the experimental group than in the control group (p < 0.05). In the experimental group immunohistochemical staining on newly formed cartilage was more intense for type-II collagen in the matrix and RT-PCR from regenerated cartilage detected mRNA for type-II collagen in mature chondrocytes. These findings suggest that repair of cartilage defects can be enhanced by the implantation of cultured mesenchymal stem cells.

Abstract
Acetabular cartilage with subchondral bone was taken from the superior dome from 15 hips of 13 patients undergoing total hip arthroplasty due to osteonecrosis of the femoral head. The mean age of the patients was 40 years. There were 10 hips ARCO stage IIIA, and 5 hips stage IIIB. 3 of the cases were mild, 12 moderate, and 1 had severe arthrosis. The degree of collapse of the femoral head was significantly related to the degeneration of the acetabular cartilage on histological examination. Our observations support the view that patients with an ARCO Stage III hip do not benefit from head-preserving procedures. They may also explain why bipolar prosthesis gives poorer results than total hip arthroplasty, in cases of osteonecrosis of the femoral head.

Abstract
BACKGROUND AND PURPOSE Malformations of cerebral cortical development are common anomalies of the brain, typically causing developmental delay or seizures that are classically thought to begin in childhood. We present clinical and MR imaging data of 16 patients with cortical malformations in whom evidence of neurologic dysfunction was first noted in adulthood, and attempt to determine whether these malformations had any differentiating features from those presenting in childhood. METHODS Imaging studies and clinical records of 16 patients with adult-onset neurologic dysfunction were reviewed retrospectively. The patients ranged in age from 17 to 64 years (mean age, 35 years) at the time of imaging. Imaging findings were correlated with seizure history. RESULTS Fourteen patients had subependymal heterotopia (seven women, seven men), and two patients had closed-lip schizencephalies. Eleven patients had epilepsy, with age of onset ranging from 14 to 45 years (mean age, 22 years); four of them were successfully controlled by medication. The remaining five patients had no seizure disorder. All patients, except one, had normal intelligence. The bilaterality or multiplicity of location of heterotopias was not associated with the presence or absence of seizures, seizure frequency, or electroencephalographic results. CONCLUSION Subependymal heterotopia and small closed-lip schizencephaly may have minor clinical manifestations that are not evident until adulthood, or may, occasionally, never cause neurologic signs or symptoms whatsoever.
