BACKGROUND Resistant ventricular fibrillation, refibrillation. and diminished myocardial contractility are important factors leading to poor survival after cardiac arrest. We hypothesized that dantrolene improves survival after ventricular fibrillation (VF) by rectifying the calcium dysregulation caused by VF. METHODS AND RESULTS VF was induced in 26(More)
BACKGROUND Pandemic flu had at least two waves in Iran. Knowing how many of the general population were already exposed to this infection has a major impact on national preventive measures. As of December 30, 2009, a total of 3672 confirmed cases of human infection with a novel Influenza A (2009 H1N1) virus had been reported in Iran with 140 deaths. (More)
BACKGROUND Population based studies on prevalence and risk factors of NAFLD in Iranian population are few. The prevalence of NAFLD and non alcoholic steatohepatitis (NASH) in Iranians varies from 2.9% to 7.1% in general population and 55.8% in patients with type 2 diabetes mellitus. OBJECTIVES To determine the prevalence and determinants of non alcoholic(More)
BACKGROUND Possible beneficial effects of dietary omega-3 supplementation on patients with congestive heart failure (CHF) were investigated. METHODS AND RESULTS 100 patients with CHF who had a tri-chamber pacemaker and automated defibrillator were initially recruited, and 70 agreed to participate.38 patients received 2 g/day of omega-3 and 32 received(More)
BACKGROUND Prisoners and injecting drug users are at constant risk of hepatitis B virus (HBV) infection and the classic 6-months HBV vaccination might not provide immunization rapidly enough. In this randomized clinical trial we investigated the efficacy of an accelerated vaccination protocol vs. classic schedule among prisoners in Iran. METHODS 180(More)
Barakat syndrome, also known as hypoparathyroidism, sensorineural deafness, and renal dysplasia syndrome is an extremely rare congenital disorder. Different etiologies are described for the syndrome but the definite pathophysiology remains unclear. Hereby, we present a case of Barakat syndrome who was diagnosed on the basis of clinical and molecular data.
Pre-shock waveform analysis for optimizing the timing of shock delivery could be immensely helpful to emergency medical personnel in treating ventricular fibrillation. For this purpose, our proposed method resolves the pre-shock surface electrocardiogram into independent sources using a blind source separation approach. The electrocardiogram pre-shock(More)
OBJECT Postprocedural hypotension and bradycardia are important complications of carotid artery stenting (CAS) and are referred to as hemodynamic instability (HI). However, the incidence and impact of HI on the short-term prognosis of patients have been of a large debate. METHODS Twenty-seven patients were selected based on NASCET criteria, and they(More)
Cardiac arrest is associated with a very high rate of mortality, in part due to inadequate tissue perfusion during attempts at resuscitation. Parameters such as mean arterial pressure and end-tidal carbon dioxide may not accurately reflect adequacy of tissue perfusion during cardiac resuscitation. We hypothesised that quantitative measurements of tissue(More)
Since 2007, Iran's Ministry of Health carried out a nationwide hepatitis-B vaccination campaign for 17-year-old adolescents in four stages. We report the outcomes of the second and third stages targeting adolescents born during 1990 and 1991. The National Committee for Hepatitis selected a passive approach--media education--for mass vaccination. (A(More)
