· Myocarditis was recently examined quantitatively as inflammation of the heart muscle based on endomyocardial biopsy, and its noninvasive diagnosis remains unsatisfactory. · Additionally, numerous miRNAs (miR-155, miR-146b, miR-590, miR-221, miR-222, etc.) coupled with inflammation or viral activation have been examined in myocarditis patients or mouse models. · The recent identification of mmu-miR-721 (has-miR-Chr8: 96), a myocarditis-specific microRNA, demonstrated its potential as an acute myocarditis biomarker. |
Acute fulminant myocarditis (AFM) occurs as an inflammatory response to an initial myocardial insult. Its rapid and deadly progression calls for prompt diagnosis with aggressive treatment measures. The demonstration of its excellent recovery potential has led to increasing use of mechanical circulatory support, especially extracorporeal membrane oxygenation (ECMO). Arrhythmias, organ failure, elevated cardiac biomarkers, and decreased ventricular function at presentation... |
Survival rates of preterm infants have improved in the past few decades, and central venous catheters play an important role in the intensive medical treatment of these neonates. Unfortunately, these indwelling catheters increase the risk of intracardiac thrombosis, and they provide a nidus for microorganisms during the course of septicemia. Herein, we report a case of persistent bacteremia due to... |

Brain natriuretic peptide (BNP) has been considered a biochemical marker for myocarditis in Kawasaki disease. We performed this study to determine its quantitative significance. We attempted to correlate log-transformed BNP concentrations (log-BNP) and clinical, laboratory, and echocardiographic variables in 81 children with Kawasaki disease. Stepwise multiple linear regression analysis was used to determine the variables independently associated with log-BNP concentration. Serum C-reactive... |
There is currently little evidence to support intravenous immune globulin (IVIG) therapy for pediatric myocarditis. The purpose of our retrospective study was to assess the effects of IVIG therapy in patients with presumed myocarditis on survival and recovery of ventricular function and to determine the factors associated with its poor outcome. We reviewed all consecutive cases of patients with myocarditis with... |
Myocarditis represent an important condition encountered by general pediatricians & general practitioners. Its presentation is varied, and therefore a high index of suspicion must be maintained when the possibility of myocarditis is raised. A progression from viral myocarditis to dilated cardiomyopathy has long been hypothesized. Treatment is initially aimed at achieving hemodynamic stability and is largely supportive. There is currently... |
Left ventricular thrombus is mainly caused by anterior myocardial infarction or severe cardiac wall dysfunction of the apex, and is rarely caused by a complication of acute myocarditis. A 12-year-old female who developed symptoms of motor dysphasia and incomplete hemiparesis of the right side was admitted to the hospital. The brain MRI taken on the day of her admission showed... |
Constrictive pericarditis represents a rare cause of protein-losing enteropathy in children. Reported is an 11-year-old girl with protein-losing enteropathy (PLE) as the principal manifestations of constrictive pericarditis. After total pericardiectomy, symptoms and signs of PLE disappeared. Doppler echocardiography including tissue Doppler imaging is a useful noninvasive initial diagnostic tool for differential diagnosis of diastolic heart failure. |
