The use of rivaroxaban, a factor Xa inhibitor, has been increasing for prevention of ischemic stroke and systemic embolism in patients with non-valvular atrial fibrillation (AF) in Japan. We conducted the nationwide multicenter study, termed as the EXPAND Study, to address its effectiveness and safety in the real-world practice of patients with non-valvular AF in Japan. The EXPAND Study is a prospective, non-interventional, observational cohort study to evaluate the effectiveness and safety of rivaroxaban in non-valvular AF patients in a real-world clinical practice...

Natural killer (NK) cells have long been considered short-lived effectors of innate immunity. However, recent animal models and human studies suggest that subsets of NK cells have adaptive features. We investigate clonal relationships of various NK cell subsets, including the adaptive population, by taking advantage of naturally occurring X-linked somatic PIGA mutations in hematopoietic stem and progenitor cells (HSPC) from patients with paroxysmal nocturnal hemoglobinuria (PNH). The affected HSPCs and their progeny lack expression of glycosylphosphatidylinositol (GPI) anchors on their cell surfaces, allowing quantification of PIGA-mutant (GPI-negative) HSPC-derived peripheral blood cell populations...

OBJECTIVE: To assess the effect of intratympanic methylprednisolone (ITMP) in posterior canal benign paroxysmal positional vertigo (BPPV) that fails treatment involving repositioning maneuver in a case series. MATERIALS AND METHODS: Nine patients with persistent posterior canal BPPV after 6 or more repositioning maneuvers were treated by ITMP (two weekly doses of 0.3-0.4 mL at 40 mg/mL) before repeating the repositioning procedures. RESULTS: Following ITMP treatment, 7 out of 9 patients were relieved of their symptoms and did not exhibit positional nystagmus after 1 or 2 repositioning maneuvers...

BACKGROUND: Although several studies have reported an association between atrial fibrillation (AF) and alcohol, the impact of alcohol consumption on the outcome after catheter ablation (CA) for AF has not been discussed. We aimed to elucidate the effect of alcohol consumption on the outcome of CA for paroxysmal AF. METHODS AND RESULTS: We examined 1361 consecutive patients with paroxysmal AF (mean age, 61±11 years, 334 women) who underwent CA, including 623 (45...

The mitochondrial pyruvate dehydrogenase enzyme complex (PDHC) plays an important role in aerobic energy metabolism and acid-base equilibrium. PDHC contains of 5 enzymes, 3 catalytic (E1, E2, E3) and 2 regulatory, as well as 3 cofactors and an additional protein (E3-binding protein) encoded by nuclear genes. The clinical presentation of PDHC deficiency ranges from fatal neonatal lactic acidosis to chronic neurologic dysfunction without lactic acidosis. Paroxysmal neurologic problems such as intermittent ataxia, episodic weakness, exercise-induced dystonia and recurrent demyelination may also be seen although they are rare...

INTRODUCTION: Data from an EEG is not commonly used by psychiatrists to plan treatment and medication. However, EEG abnormalities such as isolated epileptiform discharges (IEDs) are found to be more prevalent in psychiatric patients, particularly those diagnosed with Autism Spectrum Disorder (ASD). Most medications prescribed for ASD lower seizure threshold and increase side-effects. Therefore, it may be prudent to order an EEG for ASD cases, especially those categorized as refractory...

BACKGROUND: Analog blanking periods (BP) that hold down the display of electrograms (EGM) in cardiac rhythm devices have received much less attention than the well-known digital blanking periods which do not influence the EGM display. In Biotronik devices, when a paced event initiates an analog BP in one chamber [right atrium (RA), right ventricle (RV) or left ventricle (LV)], an identical cross-chamber analog BP starts in the other 2 chambers. METHODOLOGY: All clinical observations were recorded from patients with Biotronik devices...

Hereditary paroxysmal dyskinesias (PxD) are a heterogeneous group of movement disorders classified by frequency, duration, and triggers of the episodes. A young-adult onset canine PxD has segregated as an autosomal recessive trait in Soft-Coated Wheaten Terriers. The medical records and videos of episodes from 25 affected dogs were reviewed. The episodes of hyperkinesia and dystonia lasted from several minutes to several hours and could occur as often as >10/day. They were not associated with strenuous exercise or fasting but were sometimes triggered by excitement...

Sickle cell disease is a hemoglobinopathy that results in paroxysmal arteriolar occlusion and tissue infarction that can manifest in a plurality of tissues. Rarely, these infarcted crises manifest in the bony orbit. Orbital infarction usually presents with acute onset of periorbital tenderness, swelling, erythema, and pain. Soft tissue swelling can result in proptosis and attenuation of extraocular movements. Expedient diagnosis of sickle cell orbital infarction is crucial because this is a potentially sight-threatening entity...

BACKGROUND: Higher red cell distribution width (RDW) predicts adverse events in patients with cardiovascular diseases. However, there are limited data regarding the relationship between RDW and thromboembolism risk in the patients with atrial fibrillation (AF). We aimed to investigate the association between RDW and CHADS2, CHA2DS2-VASc scores used for the evaluation of thromboembolic risk in patients with non-valvular atrial fibrillation (AF). METHODS: Our study included 99 patients with AF (68 paroxysmal AF; 31 persistent AF)...

Phaeochromocytomas and paragangliomas are relatively uncommon tumours which may be manifest in many ways, specifically as sustained or paroxysmal hypertension, episodes of palpitations, sweating, headache and anxiety, or increasingly as an incidental finding. Recent studies have shown that an increasing number are due to germline mutations. This review concentrates on the diagnosis, biochemistry and treatment of these fascinating tumours.

Panic disorder is characterized by the paroxysmal occurrence and fear of bodily symptoms. In recent years it has been proposed that patients "learn" to fear cardiorespiratory sensations through interoceptive conditioning. This study sought to model the initial stage of this process in healthy volunteers (N=44) using mild cardiac sensations. An additional aim was to explore whether anxiety sensitivity - a known risk factor for panic disorder - modulates such interoceptive learning. Infusions of pentagastrin and saline were used to manipulate the presence versus absence of cardiac sensations, respectively, and served as conditioned stimuli in a differential interoceptive conditioning paradigm...

RATIONALE: Optimal secondary prevention of embolic stroke of undetermined source is not established. The current standard in these patients is acetylsalicylic acid, despite high prevalence of yet undetected paroxysmal atrial fibrillation. AIM: The ATTICUS randomized trial is designed to determine whether the factor Xa inhibitor apixaban administered within 7 days after embolic stroke of undetermined source, is superior to acetylsalicylic acid for prevention of new ischemic lesions documented by brain magnetic resonance imaging within 12 months after index stroke...

Autoimmune hemolytic anemia (AIHA) in childhood, including paroxysmal cold hemoglobinuria, is an uncommon, potentially life-threatening disorder. AIHA is a recognized complication of several varieties of lymphoproliferative disorders, including high-grade B-cell lymphoma, but it has not been associated with Burkitt lymphoma in people without an underlying immunodeficiency. When AIHA occurs in association with lymphoproliferative disorders, it may precede or accompany the diagnosis of malignant disease or herald relapse...

BACKGROUND: Paroxysmal atrial tachyarrhythmias frequently occur in beta-thalassemia major (β-TM) patients. The aim of the current study was to evaluate the atrial electromechanical delay (AEMD) in a large β-TM population with normal cardiac function and its relationship to atrial fibrillation (AF) onset. METHODS: Eighty β-TM patients (44 men, 36 women), with a mean age of 36.2 ± 11.1 years, and 80 healthy subjects used as controls, matched for age and gender, were studied for the occurrence of AF during a 5-year follow-up, through 30-day external loop recorder (ELR) monitoring performed every 6 months...

PURPOSE: Catheter radiofrequency ablation (RFA) is an effective treatment for symptomatic paroxysmal atrial fibrillation (AF). It has been demonstrated that the multielectrode pulmonary vein ablation catheter (PVAC) has favourable outcomes at 6-12 months post-ablation, but there are only few studies with a long-term follow-up. METHODS: We retrospectively reviewed 77 consecutive PVAC procedures in our centre, from November 2007 to December 2012. RFA was attempted in patients with symptomatic paroxysmal AF (mean age 58...
