BACKGROUND Fever is known to unmask the Brugada pattern on the electrocardiogram (ECG) and trigger ventricular arrhythmias in patients with Brugada syndrome. Genetic studies in selected cases with fever-induced Brugada pattern have identified disease-causing mutations. Thus, "fever-induced Brugada" is a recognized clinical entity. However, its prevalence(More)
BACKGROUND The skin of the scalp is relatively thick, minimally mobile, with distinct hair distribution. TopClosure® is a novel device for skin stretching and secure wound closure. OBJECTIVES To evaluate the efficacy of the TopClosure® system in primary closure of moderate and large scalp defects, as a substitute for skin grafts, flaps, and tissue(More)
Stress-relaxation is a well-established mechanism for laboratory skin stretching, with limited clinical application in conventional suturing techniques due to the inherent, concomitant induction of ischemia, necrosis and subsequent suture failure. Skin defects that cannot be primarily closed are a common difficulty during reconstructive surgery. The(More)
BACKGROUND Cardiac resynchronization therapy (CRT) is a non-pharmacological option for patients with heart failure and interventricular dyssynchrony. Elevated red cell distribution width (RDW) reflects higher size and heterogeneity of erythrocytes and is associated with poor outcome in patients with chronic heart failure. OBJECTIVES To examine the(More)
BACKGROUND Specific T-wave patterns on the resting electrocardiogram (ECG) aid in diagnosing long QT syndrome (LQTS) and identifying the specific genotype. However, provocation tests often are required to establish a diagnosis when the QT interval is borderline at rest. OBJECTIVE The purpose of this study was to determine whether T-wave morphology changes(More)
Our aim was to evaluate the mortality rate and occurrence of complications in patients aged <75 versus ≥75 years with ST-elevation myocardial infarction (STEMI). We studied 1,657 consecutive patients with STEMI hospitalized in the cardiac intensive care unit during 2008 to 2014. All patients underwent primary percutaneous intervention, of which 292 (18%)(More)
BACKGROUND Atrial fibrillation (AF) is a well-known complication in the setting of ST elevation myocardial infarction (STEMI). Data on the long-term prognostic implications of New-Onset AF (NOAF) complicating STEMI in the era of complete revascularization remains controversial. Our aim therefore was to evaluate the long-term prognosis of prior AF (pAF) and(More)
PURPOSE To examine an association between red blood cell distribution width (RDW) and the prognosis of influenza patients. METHODS We conducted a retrospective analysis of patients hospitalized with influenza during 2012-2015 in the internal medicine wards of one medical center. RDW measurements during hospitalization were analyzed. Primary outcome was(More)
BACKGROUND Cardiac arrest may result from seemingly innocuous medications that do not necessarily have cardiac indications. The best-known example is the drug-induced long QT syndrome. A less known but not necessarily less important form of drug-induced proarrhythmia is the drug-induced Brugada syndrome. OBJECTIVE The purpose of this study was to identify(More)
INTRODUCTION Health care demand is increasing due to greater longevity of patients with chronic comorbidities. This increasing demand is occurring in a setting of resource scarcity. To address these changes, high-value care initiatives, such as telemedicine, are valuable resource-preservation strategies. This study introduces the Roth score as a(More)
