Importance and repercussions of renal and cardiovascular pathology on stroke in young adults: an anatomopathologic study of 52 clinical necropsies.

Introduction: Stroke in young adults has seldom been studied in a necropsy series. The objective of the present clinical necropsy-based investigation was to analyze stroke and its relationship with cardiovascular and renal pathology in young adults.

Materials And Methods: The protocols of 52 clinical necropsies with diagnoses of stroke in patients aged 18 - 49 years, performed between the years 1990-2006, were reviewed.

[A pilot study of methylphenidate and parent training in the treatment of children with attention-deficit hiperactivity disorder].

Objective: This study gives information about a parent training program and a clinical trial with a stimulant drug (methylphenidate) to reduce the symptoms of attention deficit hiperactivity disorder (ADHD) in a group of children in Venezuela.

Patients And Methods: 24 children, aged between 6 and 10 years and diagnosed as having ADHD, identified in ADHD screening days, were randomly assigned to two groups of treatment: parent training and a stimulant drug (methylphenidate).

Results: Both groups showed an improvement in their symptoms, to different degrees, after treatment.

Symptomatic bilateral xanthogranulomas of choroid plexus in a child.

Choroid plexus xanthogranulomas are uncommon lesions that occur almost exclusively in adults; most of them constitute incidental autopsy findings. A case of symptomatic bilateral xanthogranulomas of choroid plexus in a 6 year-old girl with progressive visual loss is reported. Theories on the pathogenesis of this entity are reviewed.
