PURPOSE 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. METHODS First, possible polyps within the image were extracted using geometric shape features.(More)
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)
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)
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)
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)
This paper proposes and tests an approach for an unbiased study of radar waveforms' performances. Using the ultrawide band software defined radar prototype, the performances of Chirp and Multitones are compared in range profile and detection range. The architecture was implemented and has performances comparable to the state of the art in software defined(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)
