ABSTRACT

Background and Objectives@#Inherited arrhythmia (IA) is a more common cause of sudden cardiac death in Asian population, but little is known about the genetic background of Asian IA probands. We aimed to investigate the clinical characteristics and analyze the genetic underpinnings of IA in a Korean cohort. @*Methods@#This study was conducted in a multicenter cohort of the Korean IA Registry from 2014 to 2017. Genetic testing was performed using a next-generation sequencing panel including 174 causative genes of cardiovascular disease. @*Results@#Among the 265 IA probands, idiopathic ventricular fibrillation (IVF) and Brugada Syndrome (BrS) was the most prevalent diseases (96 and 95 cases respectively), followed by long QT syndrome (LQTS, n=54). Two-hundred-sixteen probands underwent genetic testing, and 69 probands (31.9%) were detected with genetic variant, with yield of pathogenic or likely pathogenic variant as 6.4%. Left ventricular ejection fraction was significantly lower in genotype positive probands (54.7±11.3 vs. 59.3±9.2%, p=0.005). IVF probands showed highest yield of positive genotype (54.0%), followed by LQTS (23.8%), and BrS (19.5%). @*Conclusions@#There were significant differences in clinical characteristics and genetic yields among BrS, LQTS, and IVF. Genetic testing did not provide better yield for BrS and LQTS. On the other hand, in IVF, genetic testing using multiple gene panel might enable the molecular diagnosis of concealed genotype, which may alter future clinical diagnosis and management strategies.

ABSTRACT

Objective@#The purpose of this study was to determine oral intake predictors, including videofluoroscopic swallow study (VFSS) and Charlson Comorbidity Index (CCI), in patients with diseases/conditions requiring nasogastric (NG) tube feeding for dysphagia. @*Methods@#We retrospectively extracted the clinical or radiological medical records of 501 patients with internal medicine diseases who were referred for VFSS to evaluate dysphagia between January 2012 and August 2021. Our study analyzed 310 (61.9%) subjects using the NG tube out of 501 patients surveyed. The demographic features of the subjects, comorbidities, including CCI, and the VFSS results were extracted. Immediately after the VFSS test, the subjects were categorized into two groups: 153 who removed the NG tube and 157 who retained it. The chi-square test, Fisher’s exact test, and the independent t-test were used to analyze the data. We used the logistic regression analysis to determine the independent predictors of NG tube removal. The receiver operating characteristic (ROC) curve analysis was used to determine the best cut-off value of the Functional Dysphagia Scale (FDS) score for NG tube removal. @*Results@#The FDS score, the Penetration-Aspiration Scale (PAS) score, the diagnosis of aspiration pneumonia, and the presence of hemiplegia affected the NG tube removal. The optimal cut-off value for the NG tube removal was a score of 36.5 based on the FDS. @*Conclusion@#We clarified factors that may affect the NG tube removal in patients hospitalized for internal medicine disease. This study will assist in the future development of an oral intake strategy for patients with medical conditions receiving NG tube feeding.

ABSTRACT

A 29-year-old woman had 1-month history of back pain radiating into lower extremities, motor weakness, and sensory abnormalities in both lower extremities. Contrast-enhanced spinal magnetic resonance imaging (MRI) revealed a homogeneously enhancing mass at the T12∼L1 and several intradural enhancing nodular lesions at L2∼S1. Tumor resection surgery was performed and following histological examination showed that the tumor satisfied the diagnostic criteria for atypical choroid plexus papilloma (CPP). To find primary tumor sites, contrast-enhanced brain MRI, whole spine MRI, and PET-CT were carried out and additional lesions were detected at the fourth ventricle, right cerebellum, and upper thoracic spinal cord. This is a very rare case of metastatic atypical CPP that involves brain, upper thoracic spinal cord, and cauda equina with initial manifestation of radicular symptoms without clinical signs of primary brain lesion.

ABSTRACT

Cystic neoplasms of the pancreas consist of a wide range of pathological entities and are being detected more frequently due to advances in cross-sectional imaging modalities and increasing numbers of periodic health checkups. The majority of pancreatic cystic neoplasms are intraductal papillary mucinous neoplasms, serous neoplasms, and mucinous cystic neoplasms, but recently, rare cases of mucinous non-neoplastic cyst of the pancreas (MNCP) have been reported, and despite the availabilities of modern imaging systems, such as MRI and CT, the differentiation of non-neoplastic and neoplastic cysts remains challenging. Herein, we report our experience of a 65-year-old male case with an MNCP.

ABSTRACT

PURPOSE: Although common femoral artery endarterectomy (CFAE) is regarded as the standard treatment modality for common femoral artery (CFA) disease, availability of advanced endovascular techniques has resulted in an increased number of CFA disease being treated. We evaluated clinical outcomes in a contemporary series of patients who were treated for CFA disease using endarterectomy alone or combined with endovascular treatment. MATERIALS AND METHODS: We retrospectively reviewed 46 patients from November 2001 through December 2007. The treated lesions were divided into 4 groups based on operative procedure: group I (n=11), CFAE alone; group II (n=15), CFAE and iliac artery (IA) endovascular treatment; group III (n=6), CFAE and superficial femoral artery (SFA) endovascular treatment; group IV (n=14), CFAE and IA and SFA endovascular treatment or bypass surgery. RESULTS: The degree of CFA steno-occlusion was not different among the groups. The 3-year primary patency rates of each group were 88.9±10.5%, 60.0±14.5%, 62.5±21.3%, and 83.9±10.4%, respectively. The 3-year primary assisted patency rates were 100%, 70.0±13.0%, 62.5±21.3%, and 89.3±10.4%, while 3-year secondary patency rates were 100%, 80.0±13.0%, 62.5±21.3%, and 92.3±7.4%, respectively. There was no procedure-related mortality. Significant improvement of ankle-brachial index was achieved in all groups. CONCLUSION: CFAE alone is the treatment of choice for excellent patency and clinical improvement in steno-occlusive lesions confined to the CFA. In multiple steno-occlusive diseases, this procedure could be combined with endovascular procedures to reduce the operative risk in conditions with high morbidity.

ABSTRACT

BACKGROUND: Vitamin K antagonist (VKA) to prevent thromboembolism in non-valvular atrial fibrillation (NVAF) patients has limitations such as drug interaction. This study investigated the clinical characteristics of Korean patients treated with VKA for stroke prevention and assessed quality of VKA therapy and treatment satisfaction. METHODS: We conducted a multicenter, prospective, non-interventional study. Patients with CHADS2 ≥ 1 and treated with VKA (started within the last 3 months) were enrolled from April 2013 to March 2014. Demographic and clinical features including risk factors of stroke and VKA treatment information was collected at baseline. Treatment patterns and international normalized ratio (INR) level were evaluated during follow-up. Time in therapeutic range (TTR) > 60% indicated well-controlled INR. Treatment satisfaction on the VKA use was measured by Treatment Satisfaction Questionnaire for Medication (TSQM) after 3 months of follow-up. RESULTS: A total of 877 patients (age, 67; male, 60%) were enrolled and followed up for one year. More than half of patients (56%) had CHADS2 ≥ 2 and 83.6% had CHA2DS2-VASc ≥ 2. A total of 852 patients had one or more INR measurement during their follow-up period. Among those patients, 25.5% discontinued VKA treatment during follow-up. Of all patients, 626 patients (73%) had poor-controlled INR (TTR < 60%) measure. Patients' treatment satisfaction measured with TSQM was 55.6 in global satisfaction domain. CONCLUSION: INR was poorly controlled in Korean NVAF patients treated with VKA. VKA users also showed low treatment satisfaction.

ABSTRACT

Obesity and metabolic syndrome is a worldwide pandemic and associated with high cardiovascular risk. Metabolic endotoxemia (ME) is thought to be an underlying molecular mechanism. It triggers toll-like receptor 4-mediated inflammatory adipokines and causes a chronic low grade inflammatory status, which results in cardiovascular risk increase. Exercise is the best nonpharmacological treatment to improve prognosis. In this study, we examined the circulating endotoxin level in Korean obese women and investigated effects of exercise on it. Women over body mass index (BMI) 25 kg/m2 participated in a resistance training exercise, Curves. At baseline and after 12 weeks exercise, tests including blood samples were taken. In Korean obese women, the fasting endotoxin was 1.45 ± 0.11 EU/mL. Ingestion of a high calorie meal led to a peak level after 2 hours (postprandial 2 hours [PP2]) and a significant rise over the 4 hours (postprandial 4 hours [PP4]) in it (1.78 ± 0.15 and 1.75 ± 0.14 EU/mL for PP2 and PP4, P < 0.05 vs. fasting). After exercise, BMI and hip circumference were reduced significantly. The total cholesterol (TC) at fasting, PP2 and PP4 were decreased significantly. All levels of circulating endotoxin at fasting, PP2 and PP4 showed reduction. But, the peak change was only significant (baseline vs. 12 weeks for PP2; 1.78 ± 0.15 vs. 1.48 ± 0.06 EU/mL, P < 0.05). We report the circulating endotoxin level in Korean obese women for the first time. Also, we establish that energy intake leads to endotoxemia and exercise suppresses the peak endotoxemia after meal. It suggests an impact for a better prognosis in obese women who follow regular exercise.

ABSTRACT

BACKGROUND AND OBJECTIVES: Despite significant advances in the treatment of acute myocardial infarction (MI), the prevention of sudden cardiac death (SCD), the most common mode of death in patients with MI, remains challenging. Furthermore, previous Korean MI registries did not address the issue of post-MI SCD. Additional risk stratifiers of post-MI SCD are still required to compensate for the limitation of using left ventricular ejection fraction to predict lethal arrhythmic events. SUBJECTS AND METHODS: We designed the first Korean prospective nationwide multicenter registry primarily focused on SCD; the Korean noninvasive Risk Evaluation study for sudden cardiac DEath From INfarction or heart failurE (K-REDEFINE). The registry consists of 2 groups of patients presenting with (1) acute MI or (2) acute heart failure (HF) at 25 tertiary referral cardiovascular centers. The primary endpoint of the MI group study of K-REDEFINE registry is the incidence and risk factors of post-MI SCD. In particular, the association between the risk of SCD and non-invasive Holter-based electrocardiogram (ECG) variables will be evaluated, such as T-wave alternans (marker of repolarization heterogeneity) and heart rate turbulence/variability (a marker of autonomic function). Other secondary study outcomes include atrioventricular arrhythmias, HF-related admission, repeated myocardial ischemic events, stroke, and overall deaths. CONCLUSION AND PERSPECTIVE: The K-REDEFINE registry will provide new prospects for the better management of MI patients with high risk of SCD by clarifying the burden and predictors of SCD and the clinical utility of various non-invasive ambulatory ECG-based variables in risk stratification for SCD in this patient population.

ABSTRACT

Severe graft-versus-host disease (GVHD) is an often lethal complication of allogeneic hematopoietic stem cell transplantation (HSCT). The safety of clinical-grade mesenchymal stem cells (MSCs) has been validated, but mixed results have been obtained due to heterogeneity of the MSCs. In this phase I study, the safety of bone marrow-derived homogeneous clonal MSCs (cMSCs) isolated by a new subfractionation culturing method was evaluated. cMSCs were produced in a GMP facility and intravenously administered to patients who had refractory GVHD to standard treatment resulting after allogeneic HSCT for hematologic malignancies. After administration of a single dose (1x10(6) cells/kg), 11 patients were evaluated for cMSC treatment safety and efficacy. During the trial, nine patients had 85 total adverse events and the rate of serious adverse events was 27.3% (3/11 patients). The only one adverse drug reaction related to cMSC administration was grade 2 myalgia in one patient. Treatment response was observed in four patients: one with acute GVHD (partial response) and three with chronic GVHD. The other chronic patients maintained stable disease during the observation period. This study demonstrates single cMSC infusion to have an acceptable safety profile and promising efficacy, suggesting that we can proceed with the next stage of the clinical trial.

ABSTRACT

PURPOSE: Split thickness skin graft (STSG) is frequently used for reconstructing wounds. The treatment of split-thickness donor sites demands several factors: maintenance a moist condition, minimization of pain, promotion of re-epithelization and ease of care. We have performed a study to evaluate efficacy of Physiotulle® for donor site management. METHODS: A prospective study was conducted from June 2015 to December 2015 and included 20 patients undergoing surgery for reconstructive purposes with the use of STSG. The grafts harvested with a same manner and the donor sites were managed with one of the two dressing material: Physiotulle® or Bactigras®. We campared post-operative pain scale, bleeding of donor site, period of re-epithelization and donor site infection. RESULTS: All of 20 patients were well healed after application of Physiotulle® or Bactigras® dressing without any complications. Pain level was similar between two groups until 3 days after operation but Physiotulle® (4.1±0.233) showed significant (P<0.01) pain increasing on 7 days after operation compared with Bactigras® (2.9±0.277). The bleeding index score on 7 days after operation of Physiotulle® (2.5±0.167) was higher than Bactigras® (2.0±0.211) but there is no difference. Statistically (**P<0.01), the period of re-eopithelization of Physiotulle® (13.50±0.87) was significantly shorten than Bactigras® (17.25±0.65). CONCLUSION: Physiotulle® is effective in re-epithelization. We recommend applying ointment on donor site when exudate is minimized, about 7 days after operation to prevent aggravation of pain and bleeing of donor site.

ABSTRACT

PURPOSE: The purpose of management of split thickness skin graft (STSG) donor site is to promote healing process and minimize pain and infection. There are many dressing materials for managing donor site. The study aimed to compare the effect on management of donor site between Biatain Ibu® (polyurethane foam with incorporated ibuprofen) and Mepilex® (polyurethane foam coated with silicone). Especially, we focused on manage of donor site pain and treatment satisfaction. METHODS: This prospective study was conducted on 30 patients underwent STSG from January 2015 to June 2015. The grafts harvested with a same manner and the donor sites were managed with Biatain Ibu® or Mepilex®. Donor site pain, treatment satisfaction, days for re-epithelization and complication were compared between the two groups. RESULTS: All of 30 patients were well healed and there was no complications. Pain level of Biatain Ibu® (2.32±0.929) was lower than Mepilex® (4.77±1.224). Treatment satisfaction of Biatain Ibu® (8.40±0.632) was higher than Mepilex® (7.33±0.487). There is no statistically differences (P=0.455) in the days for re-eopithelization between Biatain Ibu® (14.73±0.789) and Mepilex® (14.53±0.639). CONCLUSION: The Biatain Ibu® dressing represents a valuable alternative in the management of STSG donor site by providing an appropriate wound healing, reduction of pain and improving treatment satisfaction.

ABSTRACT

PURPOSE: With the advances of knowledge in wound healing process and technology in various fields, dressing material of the split thickness skin graft (STSG) donor site was improved. Recently, biologic dressing materials attracted attention and these are used for wound management. The aim of the study was to compare the efficacy of Xe-derma® (porcine acellular dermal matrix) with Kaloderm® (cultured epithelial autografts) for treatment of the donor site. METHODS: From July 2015 to January 2016, 20 patients who had undergone STSG were enrolled. The grafts harvested with a same manner and the donor sites were managed with Xe-derma® or Kaloderm®. We compared days for re-epithelization, number of dressings, ease of application, ease of wound monitoring, pain level and complications. RESULTS: All patients managed by these dressing materials were well healed without any complications. There is no statistically difference (P=0.830) between the days for re-epithelization of Xe-derma® (11.10±0.944) and Kaloderm® (11.00±1.054). Number of dressings of Xe-derma® (1.2±0.421) was lower than Kaloderm® (2.3±0.483). Ease of application of Kaloderm® (7.40±0.516) was easier than Xe-derma® (6.36±0.343). Ease of wound monitoring of Xe-derma® (7.77±0.856) was easier than Kaloderm® (6.25±0.720). Xe-derma® was more painless in 1 day and 3 days after operation than Kaloderm®. CONCLUSION: Advantageous properties of Xe-derma® are improving wound healing, reducing pain by contact to the wound immediately after application and easy of wound monitoring due to its transparency. Therefore, we expected Xe-derma® can be used for management of various wound.

ABSTRACT

BACKGROUND AND OBJECTIVES: Sudden cardiac death (SCD) is one of the most common causes of death in patients with heart failure (HF). However, there are no available data on SCD in previous Korean HF registries. Additionally, although widely used, the utility of left ventricular (LV) ejection fraction (EF) in risk stratification for SCD is limited. SUBJECTS AND METHODS: The Korean non-invasive Risk Evaluation study for sudden cardiac DEath From INfarction or heart failurE (KREDEFINE) is the first Korean prospective, nationwide multicenter registry, primarily focused on SCD. The registry consists of 2 groups of patients presenting with (1) acute HF or (2) acute myocardial infarction (MI) at 25 tertiary referral cardiovascular centers. Using the HF-group data of the K-REDEFINE registry, the incidence and risk factors of SCD in patients with HF will be assessed. In particular, the efficacy of Holter-based ECG variables, such as T-wave alternans (marker of repolarization heterogeneity) and heart rate turbulence/ variability (maker of autonomic function), in risk stratification for SCD will be evaluated. Other cardiovascular outcomes will also be analyzed, including atrioventricular arrhythmias, HF-related admission, stroke, and overall deaths. CONCLUSION AND PERSPECTIVE: The K-REDEFINE registry will pave the way for better management of patients with HF at high risk of SCD by elucidating the burden and risk factors of SCD and the clinical utility of various non-invasive ambulatory ECG-based parameters in risk stratification for SCD in this patient population.

ABSTRACT

Unicuspid aortic valve (UAV) is an extremely rare form of congenital aortic valvular abnormality. Although UAV shows similar clinical characteristics to bicuspid aortic valve, the clinical symptoms develop at earlier age and progress at a faster pace in UAV. In this report, we are presenting a 42-year-old male with severe aortic stenosis associated with unicommissural UAV. The patients underwent a successful Bentall operation.

ABSTRACT

BACKGROUND AND OBJECTIVES: Carbon monoxide (CO) poisoning can cause tissue hypoxia and left ventricular systolic dysfunction (LVSD) requiring intensive medical management. Our objectives were to find incidence and clinical course of LVSD CO intoxicated patients and make a clinical scoring to predict LVSD. SUBJECTS AND METHODS: We included all consecutive patients with CO exposure in the emergency room. LVSD was defined by LVEF 100/min), pulmonary edema on chest X-ray, serum NT pro-BNP (>100 pg/mL), troponin-I (>0.1 ng/mL) and lactic acid (>4.0 mg/dL) after a univariate analysis. Combining these into a clinical score, according to their beta score after a multivariate analysis (rage=0-16), allowed prediction of LVSD with a sensitivity of 84% and specificity of 91% (reference ≥8, area under the curve=0.952, p<0.001) CONCLUSION: About 31% showed LVSD in patients with CO poisoning, and most of them (86%, 18 of 21 patients) recovered within 3 days. Patients with a higher clinical score (≥8) might have LVSD.

ABSTRACT

PURPOSE: In addition to chemical burn of the alimentary tract, caustic ingestion can cause severe complications including esophageal perforation, airway edema, esophageal stricture, and death. Hematological parameters have been reported to be useful inflammatory markers predicting prognoses in various clinical situations where oxidative stress is increased. We hypothesized that hematological parameters might be useful for prediction of complications after caustic ingestion. METHODS: We performed a retrospective analysis of patients admitted to our Emergency Department after caustic ingestion. The numbers of leukocytes, neutrophils, lymphocytes, and monocytes, and the neutrophil-lymphocyte ratio were compared between uncomplicated and complicated patient groups. Receiver operating characteristic curve analysis was performed for parameters that differed between the two groups. Subgroup analysis was performed according to the substance ingested, thus acid or alkali. RESULTS: Thirty-seven patients were included in our study and eight had complications. Leukocyte, neutrophil counts, and the neutrophil-lymphocyte ratio of the complicated group were higher than those of the uncomplicated group. The areas under the receiver operating characteristic curves of leukocyte counts, neutrophil counts, and the neutrophil- lymphocyte ratio, were 0.819, 0.832, and 0.750, respectively. The cut-off values of these parameters for prediction of complications were 12 060/uL, 9607/uL, and 2.72, respectively. In subgroup analysis, the leukocyte and neutrophil counts, and the neutrophil-lymphocyte ratio of complicated patients who had ingested alkali were higher than those of the uncomplicated group. CONCLUSION: Leukocyte counts, neutrophil counts, and the neutrophil-lymphocyte ratio might serve as useful predictors of complications after ingestion of caustic substances.

ABSTRACT

Pulmonary embolism is most commonly related to deep vein thrombosis of the lower extremities. However, recent studies show that the thrombosis of superficial veins can also progress to deep vein thrombosis and pulmonary embolism. To our knowledge, there is no Korean report of pulmonary embolism associated with superficial vein thrombosis. We experienced an 82-year-old woman complaining of dyspnea and chest pain. On chest dynamic computed tomography (CT), pulmonary embolism was diagnosed. To evaluate the origin of the pulmonary embolism, abdominal CT, Doppler ultrasonography, and ascending venography of both lower extremities were done. We found no deep vein thrombosis, while thrombus of the proximal left greater saphenous vein was seen. We report a case of pulmonary embolism accompanying greater saphenous vein thrombosis without deep vein thrombosis.

ABSTRACT

BACKGROUND AND OBJECTIVES: Apurinic/apyrimidinic endonuclease 1/redox effector factor-1 (APE1/Ref-1) is a multifunctional protein involved in the DNA base excision repair pathway, inflammation, angiogenesis, and survival pathways. We investigated serum APE1/Ref-1 in patients with coronary artery disease (CAD). SUBJECTS AND METHODS: Serum APE1/Ref-1 was measured with a sandwich enzyme-linked immunosorbent assay from 360 patients who received coronary angiograms. They were divided into two groups; a control (n=57) and a CAD group (n=303), the latter included angina (n=128) and myocardial infarction (MI, n=175). RESULTS: The levels of APE1/Ref-1 were higher in the CAD than the control (0.63+/-0.07 vs. 0.12+/-0.07 ng/100 microL, respectively; p<0.01). They were also higher in MI than angina (0.81+/-0.10 vs. 0.38+/-0.11 ng/100 microL, respectively; p<0.01) and different according to the thrombolysis in myocardial infarction (TIMI) flow (0.88+/-0.09 for TIMI flow 0, 1, 2 vs. 0.45+/-0.13 ng/100 microL for TIMI flow 3, p<0.01) in acute coronary syndrome. In correlation analysis, the levels of APE1/Ref-1 were positively correlated with Troponin I (r=0.222; p<0.0001) and N-terminal pro-B type natriuretic peptide (NT-proBNP, r=0.217; p<0.0001) but not high sensitivity to C-reactive protein. Also, they revealed a negative correlation with ejection fraction (EF, r=-0.221; p=0.002). However, there were no significant differences among the three groups, were divided by their levels of APE1/Ref-1, for major adverse cardiovascular events (death, recurrent MI, stroke, revascularization) (8.2 vs. 14.0 vs. 12.5%, p=ns). CONCLUSION: The levels of serum APE1/Ref-1 are elevated in CAD, and are higher in MI than in angina. They are correlated with Troponin I, NT-proBNP, and EF.

ABSTRACT

BACKGROUND: Speckle-tracking echocardiography has been applied to measure right ventricular (RV) systolic function in various diseases. However, variations in strain measurement by different vendors have limited the application of these techniques for assessment of RV function. We sought to compare two methods for the assessment of RV systolic function in patients with acute pulmonary embolism (PE). METHODS: From August 2007 to May 2011, all consecutive PE patients were prospectively included in this cohort study. Global longitudinal strains of RV measured with EchoPAC PC software (GLSRV-EchoPAC; GE Medical Systems) and velocity vector imaging (GLSRV-VVI; Siemens Medical Systems) were recorded on the same set of echocardiographic images. RESULTS: We analyzed a total of 50 patients (12 males, 68 +/- 14 years) with acute PE in this study. GLSRV-EchoPAC and GLSRV-VVI were correlated (r = 0.793, p < 0.001) and they showed significant correlations with conventional echocardiographic parameters of RV systolic function and Log B-type natriuretic peptide (BNP) level. However, GLSRV-VVI only showed significant correlations with cardiac biomarkers as serum creatinine kinase-MB (r = 0.367, p = 0.010) and tropoinin-I concentrations (r = 0.294, p = 0.040). CONCLUSION: GLSRV-VVI and GLSRV-EchoPAC showed significant correlations with conventional echocardiographic parameters of RV systolic function and LogBNP value in patients with PE.
