[Kingella kingae bone and joint infections].

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.

Harmonic voiding urosonography with a second-generation contrast agent for the diagnosis of vesicoureteral reflux.

Background: Voiding urosonography with harmonic imaging (VUS HI) has been introduced as a sensitive and radiation-free imaging method for the diagnosis and follow-up of vesicoureteral reflux (VUR) in children.

Objective: The purpose of this study was to evaluate the sensitivity of VUS HI using a second-generation US contrast agent compared to standard voiding cystourethrography (VCUG).

Materials And Methods: A total of 228 children with 463 kidney-ureter units (KUUs) underwent two cycles of VUS HI and two cycles of VCUG at the same session.

[Clinical case of the month. Fatal pertussis infection in a 2 month old infant].

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.
