Dermatoscopic and Mucoscopic Features of Lesions in Patients with Behcet's Disease.

Objective: Behcet's disease (BD), as a vasculitis, can affect small and large vessels. As dermatoscopy has been shown to improve the accuracy in diagnosis of various skin lesions especially vascular patterns, we set this study to find if there is any characteristic pattern in the dermatoscopy of Behcet's mucocutaneous lesions.

Methods: This prospective cross-sectional observational study designed to evaluate dermatoscopic features of Behcet's mucocutaneous lesions.

Identification and management of right ventricular perforation using pacemaker and cardioverter-defibrillator leads: A case series and mini review.

Right ventricular perforation is a rare but serious complication of permanent pacemaker and implantable cardioverter-defibrillator implantation, with a reported prevalence rate of 0.1-6%. Generally, there is a high incidence of asymptomatic lead perforation with otherwise normal function.

A case of dual atrioventricular nodal nonreentrant tachycardia: An unusual cause of tachycardia-induced cardiomyopathy.

We report on a 45-year-old female who developed cardiomyopathy due to incessant dual atrioventricular nodal nonreentrant tachycardia. Her condition was completely resolved by performing radiofrequency ablation of the slow pathway.

Acute effects of smoking on QT dispersion in healthy males.

Background: Cigarette smoking increases the risk of ventricular fibrillation and sudden cardiac death (SCD). QT dispersion (QTD) is an important predictor of cardiac arrhythmia. The aim of this study was to assess the acute effect of smoking a single standard cigarette containing 1.
