[A baby with spots and a fever].

A 9-months-old boy, who had had fever and otitis media during 10 days, developed oedema of both legs and erythematolivid, partly confluent papules on his legs and right auricle. We diagnosed him with 'acute haemorrhagic oedema of infancy'. This is a benign, self-limiting vasculitis of the dermis that does not require treatment.

[Burns in children: child abuse or another cause?].

Burns are common in children but it is not always clear whether the burn is accidental or not. Child abuse should always be considered. We present two children in which the diagnosis only became clear after admission and further investigation.

[A girl with a lacunar skull].

Following trauma, an X-ray was made of the head of a 5-year-old mentally impaired girl. A lacunar skull ('Lückenschädel') was seen, which was a coincidental finding. A lacunar skull develops when the fetal skull is poorly ossificated, probably due to a lack of distention of the cerebral ventricles.

[Substitution of dexamethasone for dexamphetamine due to their written and spoken similarity].

We present a 15-year-old girl and an 11-year-old boy who were prescribed dexamphetamine for treatment of Attention Deficit Hyperactivity Disorder (ADHD), and who subsequently presented with symptoms indicative of Cushing's syndrome. It turned out that both children had taken high doses of dexamethasone instead of dexamphetamine due to an error made by the pharmacist. The diagnosis of exogenous Cushing's syndrome is easily made.
