[Kingella kingae osteomyelitis]. / L'ostéomyélite à Kingella kingae.

A case of Kingella kingae osteomyelitis characterized by an early onset of cellulitis, positive blood culture and negative bone scintigraphy is reported. Exclusive of vertebral involvement, eleven cases have been described in the pediatric literature. The bacterial nature of this disorder may prove hard to demonstrate since fever, leucocytosis, and increased CRP levels are inconstant. The difficulties of isolation and growth of Kingella kingae as well as its likely resistance to antistaphylococcal agents constitute the main features of this type of infection.

[Wilson's disease with liver copper in normal concentration]. / Maladie de Wilson avec concentration hépatique en cuivre normale.

The cases of 2 children with Wilson's disease revealed by persistent hypertransaminasemia are reported. Blood ceruloplasmin concentration was low but the liver content of copper was lower than usually seen in presymptomatic forms of the disease. The apparently low liver copper concentration could be explained by an unusually important steatosis.
