Does prevalence and correlate of body dysmorphic disorder in a community sample of adolescents?
The prevalence of body dysmorphic disorder in adolescents is similar to adult samples, and probable body dysmorphic disorder is associated with comorbidity, distress and functional impairment in a community sample. Further research is required to better understand the presentation of body dysmorphic disorder in adolescents, and to improve diagnosis and treatment.
The study shows that in LQT3, spatial variations in steady-state properties result in zones of nonuniform APD gradients. These provide a substrate for functional conduction block and reentrant excitation when challenged by subendocardial "early afterdepolarization-triggered" premature beats. The study emphasizes the key importance of spatial dispersion of repolarization, whether located in epicardial or intramyocardial layers, in arrhythmia formation in LQTS.
