RESUMO
We report six cases of children with probable or confirmed Kingella kingae bone and joint infections (BJI) and discuss the role of this pathogen in the pediatric population. The advent of Polymerase Chain Reaction (PCR) led to the recognition of the importance of Kingella kingae in several human diseases, particularly in BJI affecting children aged 6 to 48 months. Kingella kingae infections in children have most often a good prognosis provided that the diagnosis is discussed, appropriate diagnostic methods are performed and effective antibiotics are prescribed.
Nous rapportons 6 cas probables ou confirmés d'infections ostéoarticulaires (IOA) à Kingella kingae et proposons une revue de l'implication de ce pathogène en pédiatrie. L'avènement de la PCR (Polymerase Chain Reaction) a mis en lumière son rôle dans diverses maladies humaines, en particulier les IOA chez les enfants âgés de 6 à 48 mois. Le pronostic des infections à Kingella kingae chez l'enfant est le plus souvent bon, pour autant que le diagnostic soit évoqué, que les méthodes diagnostiques adéquates soient utilisées et qu'une antibiothérapie appropriée soit instaurée.

The incidence of B pertussis has increased by 50% from the 1980s to the 1990s, primarily among those aged 4 months and younger. Worldwide, pertussis is a significant cause of infectious mortality with 40 million cases and 400.000 deaths. Most of these cases and deaths occur in infancy. Symptoms vary from common cold in adults to respiratory distress in infants. Non immune babies with respiratory disease and significant lymphocytosis should be considered to have pertussis until proven otherwise. The onset of severe pulmonary hypertension during B pertussis pneumonia is frequenly rapid and relentless. Exchange-transfusion can be life-saving by reducing the leucocyte mass. Classic vaccination or boosters given to adults and adolescents would reduce the spread from parents tho infants, but a new vaccination schedule is under investigation at Vanderbilt Children's Hospital to give baby's first pertussis vaccination at birth?
