Methicillin-sensible causing endocarditis, with cerebral and orthopaedic complications, in a 17-month-old child with no risk factor.

We report a case of endocarditis, with large vegetation, in a 17-month-old male infant, complicated with meningitis, ischaemic strokes and osteoarthritis leading to haemorrhagic stroke by aneurysm rupture. He did not present any risk factor for endocarditis. The final course was favourable through, after valve replacement.

[The use of nitrous oxide and oxygen in paediatric emergency departments].

The treatment of pain, particularly in infants, is today a public health priority. The mix of nitrous oxide and oxygen, colloquially known as 'gas and air' is an important analgesia for infants for short, painful procedures. Its fast action and almost immediate reversibility when the child stops inhaling facilitates its use and its tolerance.

[Self-healing Hashimoto-Pritzker histiocytosis].

Unlabelled: Congenital 'self-healing' Langerhans' cell histiocytosis of Hashimoto-Pritzker is a rare disease occurring mainly in the neonatal period.

Case Report: We report on the case of a newborn with widespread eruption since birth, consisting of nodules, papulonodules, sometimes with ulcerations and scabs, concerning all the body, with a predilection for the cephalic area and the scalp, without general abnormalities. The clinical examination, histopathological data, immunohistochemistry, and the benign evolution in nine-, 18- and 24-month periods without particular treatment define the diagnosis of congenital self-healing Langerhans' cell histiocytosis of Hashimoto-Pritzker.
