[Evolution of third-generation cephalosporin resistance in Enterobacteriaceae from 2000 to 2008 in a Perpignan hospital]. / Evolution de la résistance des entérobactéries aux céphalosporines de troisième génération de 2000 à 2008 au centre hospitalier de Perpignan.

The aim of this work was to evaluate the evolution of Enterobacteriaceae resistance to third generation cephalosporin (3CG) from 2000 to 2008 at Perpignan hospital. Were observed: the percentage of strains isolated from short stay wards, intensive care unit and medium and long-term care facility. The percentage of strains isolated from: urine, suppuration, tracheal aspiration, and blood have been evaluated. The proportion of Escherichia coli (E. coli) strains among the Enterobacteriaceae strains intermediate (I) or resistant (R) to 3GC was also evaluated.The number of Enterobacteriaceae intermediated (I) or resistant (R) to 3GC increased (402 %).The distribution of species I or R to 3GC has changed, decrease of Klebsielle pneumoniae and Enterobacter aeorogenes species, Escherichia.coli and Enterobacter cloacae became dominant in 2008. We noted the change of isolated species distribution, urines represent the main source of multiresistant Enterobacteriaceae (MRE), 72 % of strains. The profile of patients colonised or infected by MRE has changed. Patients mainly infected with hospital acquirred MRE changed to MRE colonised patients carrying the strain into the hospital. The association of fluorinated quinolone resistance and Extended-Spectrum Beta-Lactamase Enterobacteriaceae represented 51 % in 2000, became stable at 73 % from 2002. The association of fluorinated quinolone resistance and high-level Enterobacteriaceae cephalosporinase has increased from 21 % in 2000 to be stable at 50 % since 2006. The mesures to contain the spread of MRE strains remained inefficient because of outpatients circulation, multiresistant E. coli being community species.

Treatment results with light wires studied by panoramic radiography.

The purpose of this investigation is to evaluate "parallelism" and the incidence of root resorption in fifty-three extraction cases treated with light continuous wire therapy, following the principles of minimum force application, minimum tooth movement, avoiding the outward displacement of the roots from the apical bases, and a minimum time of active treatment. Differential tooth movement was performed and active displacement of the full complement of teeth was avoided when possible, according to the needs of the particular case. Panoramic radiographs were taken before and after active treatment and 1 year out of retention. The long axes of upper and lower canines and second premolars were traced and the angulation between them was measured to appraise root "parallelism." Only 1.8 percent root resorption was estimated for those teeth measured. A possible explanation for this low figure may be the mesiodistal movement of the teeth along the apical bone base, without deviations toward the labiobuccal or lingual sides.
