OBJECTIVE To document more fully the characteristics of chronic recurrent multifocal osteomyelitis (CRMO) in pediatric patients, to collect data on the outcomes and management of the disease, and to define prognostic factors. METHODS One hundred seventy-eight patients were included (123 female patients and 55 male patients), with a mean ± SD age at(More)
BACKGROUND Pneumococcal serotypes 1, 3, 5, 7F, and 19A were the most implicated in community-acquired pneumonia (CAP) after implementation of 7-valent pneumococcal conjugate vaccine (PCV7). In France, the switch from PCV7 to 13-valent pneumococcal conjugate vaccine (PCV13) occurred in June 2010. An active surveillance network was set up to analyze the(More)
Aichi virus has been proposed as a causative agent of gastroenteritis. A total of 457 stool specimens from children hospitalized with acute diarrhea and 566 stool specimens from adults and children involved in 110 gastroenteritis outbreaks were screened for the presence of Aichi virus by reverse transcription-PCR (RT-PCR) amplification of the genomic region(More)
Kingella kingae arthritis in children is now mainly diagnosed by PCR, which has surpassed conventional culture of joint fluid. As oropharynx colonization is the first step of Kingella kingae invasion, we prospectively investigated the possibility of cultivating it from throat swabs, in children hospitalized for K. kingae arthritis. Throat culture was(More)
Staphylococcus aureus and Streptococcus pyogenes are the two main bacteria involved in skin infections in children. Mild infections like limited impetigo and furonculosis should preferentially be treated by topical antibiotics (mupirocine or fucidic acid). Empiric antimicrobial therapy of dermohypodermitis consists in amoxicillin-clavulanate through oral(More)
BACKGROUND Procalcitonin (PCT) concentration increases in bacterial infections but remains low in viral infections and inflammatory diseases. The change is rapid and the molecule is stable, making it a potentially useful marker for distinguishing between bacterial and viral infections. METHODS PCT concentration was determined with an immunoluminometric(More)
To gain further insight into the mechanism by which lactobacilli develop antimicrobial activity, we have examined how Lactobacillus acidophilus LB inhibits the promoted cellular injuries and intracellular lifestyle of Salmonella enterica serovar Typhimurium SL1344 infecting the cultured, fully differentiated human intestinal cell line Caco-2/TC-7. We showed(More)
Rotavirus is recognised as the most important agent of severe acute gastroenteritis (AGE) in young children. In a 2-year prospective survey, we investigated the epidemiology and clinical features of the viral and bacterial pathogens in children hospitalised for AGE. The study was performed in a Parisian teaching hospital from November 2001 to May 2004.(More)
Lysteriolysin O (LLO) induces a microtubule-dependent activation of mucin exocytosis in the human mucin-secreting HT29-MTX. Cholesterol inhibits the LLO-induced mucin exocytosis, whereas the oxidized form of cholesterol had no inhibitory effect. LLO-induced mucin exocytosis inhibited by cholesterol can be restored by enzymatic treatment with cholesterol(More)
We investigated an otherwise healthy patient presenting two episodes of staphylococcal cellulitis and abscesses, accompanied by high fever and biological signs of inflammation but, paradoxically, with no detectable increase in serum levels of C-reactive protein (CRP), an IL-6-responsive protein synthesized in the liver. Following in vitro activation of(More)
