OBJECTIVE: Few studies have prospectively evaluated the diagnostic accuracy and temporal impact of ultrasound in the emergency department (ED) in a randomized manner. In this study, we aimed to perform a randomized, standard therapy controlled evaluation of the diagnostic accuracy and temporal impact of a standardized ultrasound strategy, versus standard care, in patients presenting to the ED with acute dyspnea.METHODS: The patients underwent a standardized ultrasound examination that was blinded to the team caring for the patient. Ultrasound results remained blinded in patients randomized to the treating team but were unblinded in the interventional cohort. Scans were performed by trained emergency physicians. The gold standard diagnosis (GSDx) was determined by two physicians blinded to the ultrasound results. The same two physicians reviewed all data >30 days after the index visit.RESULTS: Fifty-nine randomized patients were enrolled. The mean±standard deviation age was 54.4±11 years, and 37 (62%) were male. The most common GSDx was acute heart failure with reduced ejection fraction in 13 (28.3%) patients and airway diseases such as acute exacerbation of asthma or chronic obstructive pulmonary disease in 10 (21.7%). ED diagnostic accuracy, as compared to the GSDx, was 76% in the ultrasound cohort and 79% in the standard care cohort (P=0.796). Compared with the standard care cohort, the final diagnosis was obtained much faster in the ultrasound cohort (mean±standard deviation: 12±3.2 minutes vs. 270 minutes, P<0.001).CONCLUSION: A standardized ultrasound approach is equally accurate, but enables faster ED diagnosis of acute dyspnea than standard care.

OBJECTIVE: To explore the predicting performance of renal resistive index (RRI), semi quantitative power Doppler ultrasound (PDU) score and serum cystatin C (Cys C) for acute kidney injury (AKI) in patients with cardiac failure or sepsis. METHODS: A prospective, observational study was conducted. Critically ill patients with acute cardiac failure or sepsis admitted to the emergency intensive care unit (ICU) of Cangzhou Central Hospital from January 1st to December 31st in 2018 were enrolled. In addition to the demographic data, serum Cys C, RRI, and PDU score were measured within 6 hours after admission to ICU. Renal function was assessed on day 5 according to Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Patients who proceeded to AKI stage 2 or 3 within 5 days from admission were defined as the AKI 2-3 group; other patients were classified into the AKI 0-1 group. The differences of each index were compared in all patients, cardiac failure patients and sepsis patients between the two groups. Multivariate binary Logistic regression was carried out to identify the independent risk predictors of AKI 2-3. Receiver operator characteristic (ROC) curves were plotted to examine the values of Cys C, RRI, PDU score, and RRI+PDU in predicting AKI 2-3. RESULTS: Thirty-seven patients with cardiac failure (11 with no AKI, 10 with AKI stage 1, 3 with AKI stage 2, and 13 with AKI stage 3) and 26 patients with sepsis (8 with no AKI, 2 with AKI stage 1, 7 with AKI stage 2, and 9 with AKI stage 3) were recruited. In all patients as well as the subgroup of cardiac failure, compared with the AKI 0-1 group, acute physiology and chronic health evaluation II (APACHE II) score, sequential organ failure assessment (SOFA) score, rate of continuous renal replacement therapy (CRRT), 28-day mortality, serum creatinine (SCr), Cys C and RRI were higher in AKI 2-3 group, and urine output, PDU score were lower; in the subgroup of sepsis, rate of CRRT, SCr, and Cys C were higher in AKI 2-3 group, and urine output was lower. Multivariate Logistic regression analysis found that Cys C and PDU score were independent risk factors for AKI 2-3 in all patients [Cys C: odds ratio (OR) = 11.294, 95% confidence interval (95%CI) was 2.801-45.541, P = 0.001; PDU score: OR = 0.187, 95%CI was 0.056-0.627, P = 0.007]; RRI and PDU score were independent risk factors for AKI 2-3 in patients with cardiac failure [RRI (×10): OR = 6.172, 95%CI was 0.883-43.153, P = 0.067; PDU score: OR = 0.063, 95%CI was 0.007-0.584, P = 0.015]; Cys C was the independent risk factor for AKI 2-3 in patients with sepsis (OR = 22.830, 95%CI was 1.345-387.623, P = 0.030). It was shown by ROC curve analysis that: in the subgroup of cardiac failure, the predictive values of RRI, PDU score and Cys C were well [area under the curve (AUC) and 95%CI was 0.839 (0.673-0.942), 0.894 (0.749-0.971), 0.777 (0.610-0.897), all P < 0.01]. RRI+PDU performed best in predicting AKI (AUC = 0.956, 95%CI was 0.825-0.997, P < 0.01), and the predictive value was higher than Cys C [AUC (95%CI): 0.956 (0.825-0.997) vs. 0.777 (0.610-0.897), P = 0.034]. In the subgroup of sepsis, the predictive value of Cys C was well (AUC = 0.913, 95%CI was 0.735-0.987, P < 0.01), however, the predictive value of RRI, PDU, RRI+PDU were poor. CONCLUSIONS RRI and PDU score effectively predict AKI stage 2 or 3 in cardiac failure patients, but not in patients with sepsis. The predictive values of Cys C for AKI are similar in patients with cardiac failure or sepsis.

BACKGROUND: Hepatic hemagioendothelioma in neonatal period was rarely seen, so standard treatment does not established yet.METHODS: A retrospective analysis of patients with neonatal hepatic hemangioendothelioma at Ajou University Hospital between 2001 and 2016 was performed.RESULTS: Six patients with hepatic hemangioendothelioma in neonatal period were founded. Mean age at diagnosis was 6.1 days (range, 1-26 days). Three patients have no symptoms; diagnostic approach was prenatal ultrasonography in 2 patients, and incidental abnormal ultrasonographic findings in 1 patient, but the other 3 patients have hepatomegaly and/or congestive heart failure. Three patients were observed without treatment and the other 3 patients received medical and/or surgical treatment. Three patients of those who did not receive treatment became spontaneous regression. Of the other 3 patients, 1 patient achieved complete tumor disappearance after surgical resection, another 1 patient achieved to decrease tumor size with interferon-alpha treatment for 6 months and then had complete resolution of tumor after partial liver lobectomy, and other 1 patient who received hepatic artery embolization decreased in the size and number of lesions and then regressed gradually.CONCLUSION: Asymptomatic patients with neonatal hepatic hemangioendothelioma could have spontaneous remission, but patients with symptoms such as hepatomegaly with congestive heart failure or thrombocytopenia needed to be applied with medical and/or surgical treatment.

A 53-year-old woman was admitted with epigastric discomfort and weakness. Laboratory examination at admission showed mild anemia and proteinuria. Esophagogastroduodenoscopy revealed marked mucosal atrophy, diffuse nodularity and granular appearance with mucosal friability. Biopsy was performed on the antrum and body of the stomach. On the next day, the patient began to complain of severe dyspnea, and hypoxia was present on pulse oximetry. Therefore, emergency echocardiography was conducted and it showed restrictive cardiomyopathy along with thrombus in the left atrium. With time, heart failure was aggravated despite intensive management. The result of gastric biopsy revealed amyloid deposits which stained positively with Congo red. On immunohistochemistry study, kappa and lambda chain were present. In addition, kappa chain was significantly elevated in urine and serum on electrophoresis. Although the patient was finally diagnosed as having primary gastric amyloidosis with restrictive cardiomyopathy, her general condition rapidly deteriorated and died at 12th hospital day. When obscure gastric lesion is encountered, performing gastric biopsy is strongly recommended since it be primary gastric amyloidosis. Herein, we present an unusual case of primary gastric amyloidosis.

Cardiac magnetic resonance (CMR) imaging is now widely used in several fields of cardiovascular disease assessment due to recent technical developments. CMR can give physicians information that cannot be found with other imaging modalities. However, there is no guideline which is suitable for Korean people for the use of CMR. Therefore, we have prepared a Korean guideline for the appropriate utilization of CMR to guide Korean physicians, imaging specialists, medical associates and patients to improve the overall medical system performances. By addressing CMR usage and creating these guidelines we hope to contribute towards the promotion of public health. This guideline is a joint report of the Korean Society of Cardiology and the Korean Society of Radiology.

BACKGROUND/AIMS: Diastolic dysfunction occurs frequently in patients with chronic kidney disease (CKD) and is associated with heart failure (HF) or mortality. We investigated whether the ratio of early diastolic mitral inflow velocity to early diastolic mitral annulus velocity (E/e' ratio), estimated using tissue Doppler imaging, has prognostic value for cardiovascular morbidity and all-cause mortality in patients with CKD. METHODS: For 186 patients with CKD of stages III to V, we obtained echocardiograms with tissue Doppler imaging. A 5-year follow-up of 136 patients was performed based on hospital records and telephone interviews. The enrolled patients (79 males and 57 females) were categorized into the following CKD subgroups: stage III (n = 25); stage IV (n = 22); and stage V (n = 89). RESULTS: The average follow-up period was 30.45 months and the mean age of the patients was 61.13 years. The mortality rate after 5 years was 60.0%. The causes of death were: sepsis, 21.9%; HF, 16.2%; and sudden death, 15.2%. Age (p = 0.000), increased C-reactive protein level (p = 0.018), and increased E/e' ratio (p = 0.048) were found to correlate with mortality. Age (p = 0.000), decreased ejection fraction (p = 0.003), and increased E/e' ratio (p = 0.045) correlated with cardiovascular event. CONCLUSIONS: The E/e' ratio can predict mortality and cardiovascular events in patients with CKD who have diastolic dysfunction.

Cardiogenic unilateral pulmonary edema (UPE) is a rare clinical entity that is often misdiagnosed at first. Most cases of cardiogenic UPE occur in the right upper lobe and are caused by severe mitral regurgitation (MR). We present an unusual case of right-sided UPE in a patient with cardiogenic shock due to acute myocardial infarction (AMI) without severe MR. The patient was successfully treated by percutaneous coronary intervention and medical therapy for heart failure. Follow-up chest Radiography showed complete resolution of the UPE. This case reminds us that AMI can present as UPE even in patients without severe MR or any preexisting pulmonary disease affecting the vasculature or parenchyma of the lung.

OBJECTIVETo observe the relationship of Chinese medicine (CM) syndrome pattern with heart function detected by ultrasonic cardiography and brain natriuretic peptide (BNP) level in patients with heart failure (HF).

METHODSOne hundred and sixteen inpatients of HF hospitalized in Dongfang Hospital from January, 2007 to January, 2009 were assigned to three groups according to their CM syndrome pattern differentiated, the qi-yin deficiency group (QYD), the qi-deficiency and blood-stasis group (QDBS) and the yang-deficiency with water overflowing group (YDWO). Ultrasonic cardiographic (USCG) parameters, including left ventricular end-systolic diameter (LVEDs), left ventricular end-diastolic diameter (LVEDd) and left ventricular ejection fraction (LVEF) were detected, and blood level of BNP was measured.

RESULTSLVEF was decreased while BNP was increased in patients with syndrome patterns in the order of QYD --> QDBS --> YDWO, and showed significant difference between groups (P < 0.01); CM syndrome patterns was related with all the USCG parameters and BNP level, especially the BNP (r = 0.71, P < 0.05) and LVEF (r = -0.34, P < 0.05).

CONCLUSIONLVEF and BNP can reflect the severity of heart failure, and they could be taken as the beneficial objective and quantitative indices for syndrome pattern differentiation.

The vein of Galen aneurysm is a rare vascular malformation but it can be detected by using conventional ultrasonography and diagnosed by using power Doppler ultrasonography. The prognosis of the vein of Galen aneurysm depends on congestive heart failure caused by cerebral shunt. Embolization at proper times can provide good outcome. We report a case of spontaneous delivery at 41 weeks of gestation by a 35-year-old woman presenting with a fetal vein of Galen aneurysm is described. The vein of Galen aneurysm was prenatally diagnosed by power Doppler ultrasonography and treated postnatally by embolization. This case is a report of successful prenatal diagnosis and postnatal management of the vein of Galen aneurysm.
