BACKGROUND Neonatal bacterial meningitis remains a severe infectious disease with mortality rates varying between 10% and 15%. The clinical and bacteriologic features of neonatal meningitis collected from January 2001 to December 2007 in a French national survey are presented here. METHODS Cases of neonatal meningitis were prospectively collected by a(More)
In Europe, the introduction of monovalent meningococcal serogroup C (MenC) conjugate vaccines has resulted in a significant decline in MenC invasive disease. However, given the potential for strain evolution and increasing travel to areas of high endemicity, protection against additional serogroups is needed. In this study, the immunogenicity, measured by a(More)
OBJECTIVES To describe the different pathways of management of intussusception (IS) in infants and children in metropolitan France and to identify paediatric emergency centres that might constitute a surveillance network for IS. MATERIAL AND METHODS A questionnaire was sent to 273 paediatric emergency centres distributed across France in 2005. Modalities(More)
Wireless video capsules can now carry out gastroenterological examinations. The images make it possible to analyze some diseases during postexamination, but the gastroenterologist could make a direct diagnosis if the video capsule integrated vision algorithms. The first step toward in situ diagnosis is the implementation of 3-D imaging techniques in the(More)
OBJECTIVE To verify if preterm neonates transferred between tertiary referral centers have worse outcomes than matched untransferred infants. DESIGN Cohort study with a historically matched control group. SETTING Two tertiary-level neonatal ICUs. PATIENTS Seventy-five neonates per group. INTERVENTIONS Transfer between tertiary-level neonatal ICUs(More)
BACKGROUND This nasopharyngeal (NP) carriage surveillance study was requested by the European Agency for the Evaluation of Medicinal Products as a post-licensing commitment to determine whether the use of the pneumococcal conjugate vaccines (PCVs) including 7 then 13 valents (introduced in 2001 and 2010, respectively) caused a shift in the distribution of(More)
In neonatal intensive care units, topical agents represent an increasing part of the infection control armamentarium. Fifty-one coagulase-negative staphylococci (CNS) isolated from catheter-associated bloodstream infections in very preterm neonates were investigated in this study: 41.2% exhibited decreased susceptibility to at least one antiseptic(More)
BACKGROUND In US, pneumococcal conjugate vaccine (PCV7) had reduced the burden of AOM and changed the profile of the disease. Prior to PCV7 implementation in France, AOM represented 8% of pediatricians visits and failure rate was 12%. The aim of this study is to describe the epidemiologic characteristics of AOM after PCV7 implementation. METHODS From 2007(More)
Wireless capsule endoscopy (WCE) is commonly used for noninvasive gastrointestinal tract evaluation, including the detection of mucosal polyps. A new embeddable method for polyp detection in wireless capsule endoscopic images was developed and tested. First, possible polyps within the image were extracted using geometric shape features. Next, the candidate(More)
Using the multiple reference frames compensation in the H264 coder improves the coding efficiency for sequences which contain uncovered backgrounds, repetitive motions and highly textured areas. Unfortunately this technique requires excessive memory and computation resources. In this article, we proposed and implemented a technique based on Markov Random(More)
