The Fault Is in Our Scars

چکیده
I n this issue of iJACC, Disertori et al. (1) present a meta-analysis of the association between myocardial scar detected by cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE) and ventricular arrhythmia (VA) risk. The study included 2,850 patients from 19 different studies and 423 arrhythmic events over a median 2.8 years of follow-up. The authors defined a composite arrhythmic event endpoint that included sudden death, aborted sudden death, ventricular tachycardia, ventricular fibrillation, and appropriate implantable cardioverter-defibrillator (ICD) therapy for VA. Using this endpoint, the authors’ meta-analysis found that patients without LGE had an annual composite arrhythmia event rate of 1.7% compared with the annualized event rate of 8.6% in patients with LGE (1).

Treatment of varicella skin scars with sequential punch elevation, autologous fat injection and fractional CO2 laser
Varicella is a common viral infection that occasionally results in scar. Despite a number of measurements taken to combat this infection, they have all been either impractical or limited.The current study presents a 28-year-old woman diagnosed with varicella 10 years ago which caused her to have several depressed skin scars over the face. She was subjected to sequential treatment of punch eleva...
متن کاملFault Tolerant Reversible QCA Design using TMR and Fault Detecting by a Comparator Circuit
Quantum-dot Cellular Automata (QCA) is an emerging and promising technology that provides significant improvements over CMOS. Recently QCA has been advocated as an applicant for implementing reversible circuits. However QCA, like other Nanotechnologies, suffers from a high fault rate. The main purpose of this paper is to develop a fault tolerant model of QCA circuits by redundancy in hardware a...
متن کاملComparison of the therapeutic effect of microneedling with carbon dioxide laser in hypertrophic burn scars: a randomized clinical trial
Background: Microneedling is recently used to treat skin scars mostly atrophic scars; however, there are limited data about its effectiveness on hypertrophic burn scars. Carbon dioxide (CO2) laser is an effective method for the treatment of burn scars. Here, we aim to compare the efficacy of microneedling to CO2 laser in the treatment of hypertrophic burn scars in a randomized clinical trial. M...
