BACKGROUND Predicting tachycardia-induced cardiomyopathy (TIC) in patients presenting with left ventricular (LV) dysfunction and tachyarrhythmias remains challenging. We assessed the diagnostic value of early right ventricular (RV) dysfunction to predict TIC using cardiac magnetic resonance (CMR) imaging. METHODSANDRESULTS A total of 102 consecutive patients with newly diagnosed LV dysfunctio...

This article reflects discussion by the WHO ICD-11 Working Group on the Classification of Obsessive-Compulsive and Related Disorders. After reviewing the historical classification of tic disorders, this article discusses their placement in ICD-11. Existing problems with diagnostic labels and criteria, appropriate placement of the tic disorders category within the ICD-11 system, and pragmatic fa...

There has been growing interest in the association between infectious disease and mental disorders, but an association between enterovirus (EV) infection and tic disorders has not been sufficiently explored. Herein, we aim to investigate the association between EV infection and incidence of tic disorders in a nationwide population-based sample using Taiwan's National Health Insurance Research D...

BACKGROUND Tourette syndrome and chronic tic disorder are heritable but aetiologically complex. Although environment plays a role in their development, existing studies of non-genetic risk factors are inconsistent. AIMS To examine the association between pre- and perinatal exposures and Tourette syndrome/chronic tic disorder in the Avon Longitudinal Study of Parents and Children (ALSPAC) pros...

purpose: to evaluate the etiologies of excessive blinking in children and teenagers less than 18 years of age in hamedan, iran. methods: this study was performed during 2009-2010 as a cross-sectional study on 50 children and teenagers less than 18 years old who were referred to sheikh-al-reis and farshchian clinics in hamedan for abnormal and excessive blinking. ophthalmic and neurologic examin...

Titanium carbide (TiC) nanocrystals were recently proposed as the carrier of the mysterious 21 mm emission feature observed in post–asymptotic giant branch stars, based on their close spectral match and the presolar nature of meteoritic TiC nanograins (which reveals their stellar ejecta origin). But we show in this Letter that the KramersKronig dispersion relations, which relate the wavelength-...

Both epilepsy and tic disorders may share common mechanisms with the involvement of abnormal cortical-basal ganglion circuit connection and dopaminergic dysfunction. However, the association between epilepsy and tic disorders has never been studied. This study investigated the risks of developing tic disorders among children with epilepsy using databases of a universal health insurance system i...
