Polymyalgia rheumatica (PMR) represents the most common inflammatory rheumatic disease of the elderly. It is characterized by synovitis of proximal joints and extra-articular synovial structures, along with chronic high-grade systemic inflammation. PMR is closely related to giant cell arteritis (GCA), a large-vessel vasculitis that involves the major branches of the aorta, particularly the extracranial branches of carotid artery including temporal arteries. It is currently believed that PMR and GCA may represent different manifestations of the same disease process...

PURPOSE: Recent studies suggest that atrial fibrillation (AF) is associated with increased cardiovascular risk and mortality including sudden cardiac death (SCD). According to the Cardiovascular Heath Study cohort, the incident rate of SCD was higher in the AF population (2.9 per 1000 per year) compared with non-AF controls (1.3 per 1000 per year). In this study, we performed a systematic review and meta-analysis to explore the association between AF and SCD. METHODS: We comprehensively searched the databases of MEDLINE and EMBASE from inception to January 2017...

Long QT syndrome (LQTS) is the most common cardiac ion channelopathy and has been found to be responsible for approximately 10% of sudden infant death syndrome (SIDS) cases. Despite increasing use of broad panels and now whole exome sequencing (WES) in the investigation of SIDS, the probability of identifying a pathogenic mutation in a SIDS victim is low. We report a family-based study who are afflicted by recurrent SIDS in which several members harbor a variant, p.Pro963Thr, in the C-terminal region of the human-ether-a-go-go (hERG) gene, published to be responsible for cases of LQTS type 2...

The best hypothesis to explain Sudden Infant Death Syndrome (SIDS) pathogenesis is offered by the "triple risk model", which suggests that an interaction of different variables related to exogenous stressors and infant vulnerability may lead to the syndrome. Environmental factors are triggers that act during a particular sensible period, modulated by intrinsic genetic characteristics. Although literature data show that one of the major SIDS risk factors is smoking exposure, a specific involvement of molecular components has never been highlighted...

Dravet syndrome (DS) is a severe childhood-onset epilepsy commonly due to mutations of the sodium channel gene SCN1A. DS patients have a high risk of sudden unexplained death in epilepsy (SUDEP), believed to be due to cardiac mechanisms. Here we show that DS patients have peri-ictal respiratory dysfunction. One patient who had severe and prolonged postictal hypoventilation later died of SUDEP. Mice with an Scn1aR1407X/+ loss of function mutation died after spontaneous and heat-induced seizures due to central apnea followed by progressive bradycardia...

OBJECTIVE: Increased breathing rate, apnea, and respiratory failure are associated with sudden unexpected death in epilepsy (SUDEP). We recently demonstrated the progressive nature of epilepsy and mortality in Kcna1-/- mice, a model of temporal lobe epilepsy and SUDEP. Here we tested the hypothesis that respiratory dysfunction progresses with age in Kcna1-/- mice, thereby increasing risk of respiratory failure and sudden death (SD). METHODS: Respiratory parameters were determined in conscious mice at baseline and following increasing doses of methacholine (MCh) using noninvasive airway mechanics (NAM) systems...

The Ross procedure offers excellent short-term outcome but the long-term durability is under debate. Reinterventions and follow-up of 100 consecutive patients undergoing Ross Procedure at our centre (1993-2011) were analysed. Follow-up was available for 96 patients (97%) with a median duration of 5.3 (0.1-17.1) years. Median age of the patient cohort was 15.2 (0.04-58.4) years with 76 males. 93% had underlying congenital aortic stenosis. Root replacement technique was applied in all. The most common valved conduits used for reconstruction of the right ventricular outflow tract were homografts (66 patients) and bovine jugular vein (ContegraR) graft (31 patients)...

Objectives: According to recent publications, some patients with spinal and bulbar muscular atrophy (BSMA) develop cardiac disease, manifesting as ST-segment abnormalities, Brugada-syndrome, dilative cardiomyopathy, or sudden cardiac death. Here we present neurological and cardiac data of a BSMA patient who was followed up for 10 y. Case report: In a male patient aged 47 y, BSMA was diagnosed at age 37 y upon the typical clinical presentation (postural tremor since age 12 y, dysarthria since age 15 y, muscle cramps since age 29 y, general myalgias since age 32 y, general fasciculations since age 34 y, myoclonic jerks, easy fatigability, dyspnea upon exercise since age 36 y) and a CAG-repeat expansion of 47 ± 1 repeats in the androgen-receptor gene detected at age 37 y...

Regular physical exercise is responsible for various health benefits, and is recommended for primary and secondary cardiovascular (CV) prevention. Despite these recognized benefits, various clinical events can occur in athletes, including acute myocardial infarction and sudden cardiac death (SCD); the main cause of SCD in veteran athletes is coronary artery disease (CAD). The relationship between intense exercise training and CAD is controversial, and a U-shaped association has been hypothesized. If this is the case, screening for subclinical CAD in older athletes may be justified, and various different methodologies have been proposed...

BACKGROUND: Young patients presenting with symptomatic Brugada syndrome have very high risks for ventricular arrhythmias and should be carefully considered for implantable cardioverter-defibrillator (ICD) placement. However, this therapy is associated with high rates of inappropriate shocks and device-related complications. OBJECTIVES: This study investigated clinical features, management, and long-term follow-up of young patients with Brugada syndrome and ICD. METHODS: Patients diagnosed with Brugada syndrome, who underwent implantation of an ICD at an age of ≤20 years, were studied...

There have been dramatic improvements in reducing infant sleep-related deaths since the 1990s, when recommendations were introduced to place infants on their backs for sleep. However, there are still approximately 3,500 sleep-related deaths among infants each year in the United States, including those from sudden infant death syndrome, accidental suffocation and strangulation in bed, and unknown causes. Unsafe sleep practices, including placing infants in a nonsupine (on side or on stomach) sleep position, bed sharing, and using soft bedding in the sleep environment (e...
