Depressive symptoms among teenagers in the emergency department: prevalence estimate and concordance with parental perceptions.

Purpose: This study aims to estimate the prevalence of depressive symptoms among adolescents seen in hospital emergency departments and to investigate the concordance between self-reported adolescent depression and parental perceptions of their adolescents' health status.

Method: A multicentre cross-sectional survey in three emergency departments receiving adolescents in Ile-de-France took place in 2010. All adolescents completed a questionnaire including the Adolescent Depression Rating Scale (ADRS) and a series of questions concerning somatisation and risk behaviours.

Danon disease: intrafamilial phenotypic variability related to a novel LAMP-2 mutation.

Danon disease is an X-linked lysosomal disorder, characterized by hypertrophic cardiomyopathy, skeletal myopathy and mental retardation. We report a family with a novel mutation, in which the mother and her three sons were affected with various clinical presentations. A massive hypertrophy of the left ventricle was the predominant feature in the three male patients, with different degrees of severity of cardiac symptoms, from isolated palpitations to cardiac failure and sudden death.
