Objectives The study objectives were to describe the investigation and management of an imipenem-resistant Acinetobacter baumannii outbreak that occurred in the 15-bed ICU of a tertiary care teaching hospital (Brest, France), during the summer 2008. Patients and methods Patients harboring an imipenem-resistant A. baumannii strain were defined as case patients. We described case occurrence and steps taken to control the outbreak: contact isolation, reinforcement of hygiene procedures, unit shutdown decision, unit disinfection, and reopening. We also made a case control study and a cost analysis of the outbreak management. Results During a 10-day period, five patients were positive for a single clone of imipenem-resistant oxa-23 A. baumannii. Four patients presented with ventilation-acquired pneumonia and one was asymptomatic. The first two patients died one day after the first swab which led to the identification of A. baumannii. No additional case was noted in the ICU or in other hospital units after deciding to close the ICU. The cost of outbreak management was estimated at 264,553 euros. The case control study identified several factors associated with infection or colonization: length of stay in the ICU, chronic respiratory disease, number of previous antibiotic classes used, duration of ventilation, prone position, echocardiography, and presence of a nasogastric tube. Conclusion This outbreak occurred during the summer period requiring the shutdown of the ICU and inducing a considerable cost. Rapid reactions of the ICU staff during the outbreak enabled to limit the epidemic.

Resume La politique de lutte contre les infections nosocomiales s’appuie sur plusieurs outils permettant de prevenir la diffusion des bacteries multiresistantes. L’hygiene des mains est la mesure de prevention la plus simple et la plus efficace pour reduire la transmission croisee d’agents infectieux lors des soins. Les produits hydroalcooliques (PHA) pour l’hygiene des mains ont ete introduits recemment au CHU de Brest (2000). Les objectifs de l’etude etaient les suivants : decrire l’epidemiologie des infections nosocomiales a Staphylococcus aureus resistants a la meticilline (SARM) ; determiner les consommations annuelles d’antibiotiques antistaphylococciques ; et discuter l’impact de la consommation de produits d’hygiene des mains et d’antibiotiques sur l’epidemiologie des SARM nosocomiaux. Materiels et methodes Une etude epidemiologique et pharmacoepidemiologique retrospective a ete realisee du 1er janvier 2004 au 31 decembre 2007 au CHU de Brest. Elle a permis de mettre en evidence les cas d’infections nosocomiales a SARM et de quantifier les consommations de produits d’hygiene des mains (savon doux, savons antiseptiques, PHA) et d’antibiotiques antistaphylococciques. Resultats L’etude retrospective a montre une diminution du taux d’infections nosocomiales a SARM et une augmentation de la consommation de PHA. Les taux de resistance aux antibiotiques antistaphylococciques ont egalement diminue dans un contexte de diminution de la consommation globale d’antibiotiques sur l’etablissement.

Infectious Diseases - Abstract
Introduction Les bacteriemies sont des infections graves, dont le pronostic est directement lie a la pertinence de l’antibiotherapie. L’utilisation de nouvelles techniques microbiologiques associee a un avis infectiologique specialise pourrait ameliorer la prise en charge therapeutique de ces infections. Materiels et methodes Nous avons mene une etude quasi experimentale de type enquete avant-apres, retrospective, pour evaluer l’impact d’un conseil specialise en antibiotherapie sur la pertinence de l’antibiotherapie dans les bacteriemies vraies. Deux phases de 3 mois ont ete identifiees : une premiere impliquant la prise en charge usuelle de toute bacteriemie vraie ; une seconde comprenant, en sus, un conseil specialise en antibiotherapie par un infectiologue senior, au moment de l’identification du pathogene. La pertinence de l’antibiotherapie etait evaluee par le score de Gyssens. Resultats Ainsi, 471 bacteriemies vraies ont ete colligees : 241 en phase 1 et 230 en phase 2. En phase 1, les antibiotherapies empiriques et documentees etaient inadaptees respectivement dans 49 % (117/241) et 47 % (114/241) des cas. En phase 2, 33 % (75/230) des antibiotherapies empiriques et 38 % (87/230) des antibiotherapies documentees etaient inadaptees. L’avis infectiologique permettait donc une diminution significative des taux d’antibiotherapies inadaptees, empiriques et documentees, de 16 % et 9 % respectivement (p En phase 1, une hospitalisation en onco-hematologie, une allergie a un antibiotique et le caractere nosocomial de la bacteriemie etait significativement associes a un sur-risque d’antibiotherapie inadaptee. En phase 2, aucun facteur de risque n’etait identifie. Il n’existait pas de difference entre les deux phases concernant la duree de sejour et la mortalite a 28 jours Conclusion Un avis infectiologique permet une amelioration de la qualite de l’antibiotherapie empirique et documentee dans les bacteriemies vraies. L’implementation en routine d’un programme de gestion specialise des anti-infectieux est justifiee et necessaire pour la prise en charge des bacteriemies vraies.

Resume Cette etude menee entre 1997 et 2003 en Bretagne sur les pneumocoques responsables d'infections invasives, evalue la sensibilite aux antibiotiques et les serogroupes des souches isolees de bacteriemies, de meningites et d'otites chez les enfants et les adultes. En 2003, 62 % des souches sont de sensibilite diminuee a la penicilline, 11 % sont resistantes. La prevalence des souches resistantes a l'erythromycine atteint 63 %. Ces taux de resistances sont les plus importants dans la population infantile. Les serogroupes 14 et 19 sont les plus frequents, surtout parmi les enfants. L'emergence notable du serogroupe 19 pourrait etre due a l'utilisation du vaccin conjugue heptavalent introduit en France en 2001. La surveillance des pneumocoques reste necessaire pour detecter les serogroupes emergents et les resistances.

The authors report a rare case of Yersinia enterocolitica O:3 pneumonia in an immunocompetent 70-year old man. There was no evidence of acute gastrointestinal disease. Diagnosis was confirmed by blood cultures. He responded with resolution of the infection after 21 days of therapy with a third-generation cephalosporin then by cotrimoxazole. Only 15 cases have been reported so far. Most of the patients were immunocompromised. This is the first case in France.

Resume Le laboratoire d'hygiene hospitaliere du CHU de Brest, dans le cadre du controle du lait maternel, isole le 03 janvier 1996 une souche d' Enterobacter aerogenes secretrice d’une cephalosporinase a partir du lait maternel d'une mere d'enfant hospitalise en neonatalogie. Le 15 avril 1996 une nouvelle souche d' E. aerogenes est isolee du lait maternel d'une autre mere. Jusqu’au 18 aout 1997, 21 echantillons de lait maternel ont ete positifs pour ce germe. Pendant la meme periode, E. aerogenes a ete isole chez 26 enfants de moins d’un an, dont 11 etaient infectes et 15 colonises. Les laits maternels positifs ne correspondaient pas a ceux des meres des enfants infectes ou colonises. Toutes les souches presentaient le meme profil de resistance aux antibiotiques. L'electrophorese en champ pulse a montre que les souches des enfants et des laits maternels avaient les memes profils de restriction avec les deux enzymes utilisees. L'enquete epidemiologique a porte sur la biberonnerie et le lactarium. Le personnel de ces unites est commun. Un portage a ete recherche chez ce personnel, sans succes. La recherche d’ E. aerogenes dans l'environnement et dans les aliments pour bebes autres que le lait maternel, a ete negative. Nous n'avons pas retrouve la source de ces contaminations ; la seule hypothese que nous avons retenue est celle d'une origine commune a partir de la biberonnerie–lactarium, sans pouvoir en apporter la preuve. A la suite de cette epidemie, nous avons revu totalement avec l'equipe de la biberonnerie–lactarium les modalites de travail et les pratiques.

Resume Treize laboratoires bretons ont collecte 832 souches de Streptococcus pneumoniae en 1999 chez 312 (37,5 %) femmes et 518 (62,2 %) hommes hospitalises ou consultants. Cette population comprenait 255 (30,6 %) enfants. Cent quatre-vingt-huit (22,6 %) souches ont ete isolees d’hemocultures, 16 (1,9 %) de LCR, 449 (54 %) de prelevements pulmonaires qu’ils soient proteges (8,1 %) ou non (45,9 %) et 88 (10,6 %) de pus d’otite moyenne aigue. La diminution de la sensibilite a la penicilline G (PSDP) a ete mesuree par un disque d’oxacilline 5 μg selon les recommandations du CA-SFM. Les CMI de la penicilline G, de l’amoxicilline et du cefotaxime ont ete mesurees sur une partie des PSDP par la methode de dilution en gelose. Soixante-cinq pour-cent (546/832) des pneumocoques sont des PSDP, 33,5 % des PSDP sont resistants a la penicilline G, 2,2 % sont resistants a l’amoxicilline et 0,2 % au cefotaxime. L’activite de l’erythromycine, de la tetracycline et du cotrimoxazole, determinee par diffusion en gelose, confirme l’association de la resistance a ces antibiotiques aux PSDP. Le serotypage des PSDP retrouve les types predominants 23 (23,7 %), 14 (23,5 %) et souligne l’augmentation de frequence du type 19 (19,1 %). Dans notre region, l’augmentation constante des PSDP (1993–1994 : 28,5 % ; 1997 : 56,4 % ; 1999 : 65,6 %) pourrait peut-etre etre expliquee par l’analyse des donnees sociologiques et demographiques specifiques.

Introduction Capnocytophaga canimorsus est un bacille gram negatif commensal de la gueule du chien et du chat, transmis par contact, a culture lente, fragile et difficile a identifier. Il se place dorenavant juste derriere Pasteurella multocida pour les infections apres morsure de chien et Streptococcus pneumoniae pour les infections chez les splenectomises. Un cas avec atteinte rhumatologique et erytheme annulaire centrifuge, classiquement rares, nous ont incites a en revoir l’incidence, le contexte et l’expression clinique. Materiel et methodes Nous avons realise une extraction des patients chez lesquels une culture ou une PCR universelle a C. canimorsus se sont revelees positives a partir des bases de donnees du departement d’information medicale et du laboratoire de microbiologie du CHRU de Brest entre 2000 et 2016. Resultats Sept patients (5 hommes et 2 femmes) ont ete recenses. Ils avaient de 36 a 88 ans et trois etaient immunodeprimes (diabete, splenectomie et polyarthrite rhumatoide diabetique sous biotherapie) mais un seul avait eu une consommation d’alcool excessive (alors sevree). Trois lechages de plaie (chiens) et une griffure (chat) etaient retrouves, ainsi que la presence de chiens a domicile dans un cas. L’expression clinique predominante etait orthopedique dans deux cas (spondylodiscite, oligoarthrite), cutanee dans deux cas (plaie d’une cheville, escarre inflammatoire), meningee dans deux cas et valvulaire dans un cas. Sur le plan cutane, il existait un purpura associe a l’endocardite et un erytheme annulaire centrifuge associe a l’oligoarthrite comme possibles expressions immunologiques secondaires. Le diagnostic etait porte grâce a la culture (trois hemocultures, deux biopsies cutanees et un liquide cephalorachidien), ou par PCR universelle (spondylodiscite). L’antibiotherapie, reposant sur des C3G en grande majorite, l’association levofloxacine–clindamycine ou rifampicine–doxycycline de facon anecdotique, a ete associee dans un cas a une chirurgie (parage de la plaie de cheville). Discussion Sur le plan des manifestations cutanees, nous retrouvons dans notre serie une plaie infectee, deux portes d’entrees cutanees a type de plaies qui furent lechees, une escarre inflammatoire lechee, un erytheme annulaire centrifuge et un purpura. Dans la litterature, les atteintes cutanees sont aussi diverses : purpura, petechies, gangrene, exantheme maculopapuleux ou maculeux, plaies mais aussi un exantheme urticarien, un syndrome de Stevens-Johnson associe a un choc septique… Conclusion Il faut penser a une infection a C. canimorsus devant un purpura dans les suites d’une morsure de chien mais aussi devant des manifestations cutanees moins frequentes chez des patients presentant des facteurs de risques.

Introduction Les mesures de sectorisation et de depistage mises en place lors des episodes a bacteries hautement resistantes emergentes (BHRe) entrainent des modifications organisationnelles couteuses. L’objectif de ce travail est d’evaluer le cout du premier episode epidemique de l’etablissement en janvier 2016 (un cas index et un cas secondaire) et d’utiliser ce modele pour les episodes ulterieurs. Methodes La perte de recettes a ete evaluee a partir du nombre de journees d’hospitalisation perdues par la fermeture de lits due a la sectorisation en tenant compte du taux d’occupation de l’unite medicale a la meme periode les trois annees precedentes ; les depenses supplementaires en materiel et en moyens humains ont ete recensees aupres des cadres des unites et de l’equipe operationnelle d’hygiene, enfin les recettes supplementaires ont ete calculees par le codage de la presence des BHRe et des precautions d’isolement. Resultats Le cout de cet episode a ete estime a 76 787€ avec d’une part 90 324€ lies a la perte de recettes pour 260 journees d’hospitalisation perdues, 3913€ dus au depistage des 135 patients contacts et 1200€ pour le materiel a usage unique, et d’autre part 18 650€ de recettes supplementaires par le codage des sejours des patients porteurs de BHRe et des mesures d’isolement. Les memes methodes de calcul ont ete utilisees pour les episodes suivants, appliquees aux unites medicales concernees et avec evaluation du cout moyen du depistage par patient. De plus un recueil en temps reel des moyens materiels et humains supplementaires a ete mis en place par la direction des soins en raison des difficultes de comptabilisation a posteriori. Le cout pour l’annee 2016 pour l’etablissement a ainsi ete evalue au 31 octobre a 210 000€ dont 165 000€ dus a la sectorisation. Discussion/conclusion La perte de recettes liee a la fermeture de lits ne peut etre equilibree avec le systeme actuel de tarification, mettant les etablissements en difficulte pour appliquer les mesures pourtant recommandees pour limiter la diffusion des BHRe.

Resume Les auteurs rapportent le cas d'une reinfection d'ascite a pneumocoque resistant a la penicilline (PRP) apres traitement par amoxicilline. Les similitudes microbiologiques et genetiques des deux souches isolees suggerent qu'elles derivent d'un meme clone et supportent l'hypothese d'une rechute de l'infection au niveau peritoneal. L'amoxicilline aux doses habituelles semble insuffisante pour eradiquer le PRP du site infectieux dans l'infection spontanee d'ascite des cirrhotiques. L'action des nouvelles fluoroquinolones reste a evaluer.

Introduction We had for aim to describe control and investigation of an outbreak caused by a strain of Extended spectrum beta-lactamase producing Klebsiella pneumoniae in intensive care units of the Brest teaching hospital. Patients and method The case definition was a patient infected by or carrying the epidemic strain. Control measures and investigations are presented. A case-control study was conducted in the surgical intensive care unit. Each case was matched with two controls based on admission times in the unit. The study focused on diagnostic and therapeutic procedures, and potential contacts with healthcare workers, in this context of cross transmission. Results Between February and May 2011, nine cases were reported in the surgical ICU and two in the medical ICU. Eighteen controls were matched with the nine surgical ICU cases. Several factors were found to be statistically associated with infection or colonization by the epidemic strain: the surgical block in which patients had been operated and the ward of first hospitalization; the number of trans-esophageal and trans-thoracic echocardiographies, of central venous catheter insertions, and of surgical operations; intubation. The total number of invasive procedures was also found to be statistically higher among cases. Conclusion This study identified factors associated with colonization or infection by the epidemic strain. These factors might have been involved in the transmission tree, and be vulnerable elements for the prevention of nosocomial infections and colonisations, and their epidemic spread.

Resume L'evolution de la diminution de sensibilite de Streptococcus pneumoniae aux β-lactamines est suivie, en France, par le Centre National de Reference du Pneumocoque (CNRP). Les resultats d'une enquete regionale retrospective, effectuee dans 13 Centres hospitaliers, ont ete compares aux donnees nationales du CNRP, puis analyses par centre. Le taux moyen de resistance a la penicilline du pneumocoque dans cette region est comparable aux donnees du CNRP (13 %). L'etude montre egalement une nette difference de sensibilite selon que les souches sont considerees invasives (5,5 % de PRP) provenant d'hemocultures, LCR, prelevement bronchique protege ou non-invasives (18,6 %). Une relation entre PRP et recrutement pediatrique est mise en evidence (33 % de PRP chez les enfants). Une heterogeneite de resultats est constatee dans les differents centres incitant a discuter des biais possibles tels que le type des prelevements recus, le recrutement de patients et les methodes d'etude de la sensibilite. Les resultats de cette etude devraient inciter a un suivi epidemiologique homogene local afin de guider les choix therapeutiques.

The fight against healthcare-associated infections is based on preventive measures of multidrug resistant bacteria diffusion. Hand hygiene is the simplest and the most effective preventive measure to reduce cross-transmission of infectious agents. Hydroalcoholic solutions for hand hygiene was recently introduced in the University Hospital of Brest (France). The aims of the study were: to describe the epidemiology of healthcare-associated infections due to methicillin-resistant Staphylococcus aureus (MRSA); to determine the annual consumptions of antistaphylococcal antibiotics; and to discuss the relation between consumption of antiseptic products or antibiotics and the epidemiology of MRSA.A retrospective epidemiological and pharmaco-epidemiological study was realized from January 2004 to December 2007 in the University Hospital of Brest (France). It allowed to bring to light the cases of healthcare-associated infections due to MRSA and to quantify the consumptions of hang hygiene products and antistaphylococcal antibiotics.this retrospective study showed a decrease of healthcare-associated infections due to MRSA and an increase of the consumption of hydroalcoholic solutions. Antistaphylococcal resistance rates also decreased in a context of fall of the global antibiotics consumption in the hospital.

Resume Entre 1972 et 1989, 63 cas de listeriose ont ete diagnostiques au CHU de Brest. Nous avons observe un cycle pluri annuel dans l'apparition de l'infection et une variation saisonniere interessant le printemps. La listeriose neonatale, avec 37 cas, reste la plus frequente. Cependant, le nombre de cas chez l'adulte tend a augmenter depuis le debut des annees 80, les enfants etant exceptionnellement touches. Le mode de contamination de l'adulte est generalement inconnu ; a l'inverse, dans les formes neonatales, la transmission foetomaternelle est presque toujours responsable de l'infection du nouveau-ne, sauf dans les cas d'infection nosocomiale. Le sexe est un facteur discriminant de l'infection listerienne de l'adulte et l'immunodepression, un facteur favorisant et aggravant. Les formes neuromeningees pures s'observent preferentiellement chez l'adulte, les nouveau-nes presentant plutot une forme generalisee. Le serovar 4b est largement predominant dans notre serie. Le pronostic de l'infection est globalement bon (sauf chez l'adulte immunodeprime) du fait d'une bonne sensibilite aux antibiotiques.

Resume La frequence des infections a Lactobacillus est probablement sous-evaluee, en particulier chez les malades immunodeprimes. Les auteurs rapportent une observation de septicemie a Lactobacillus casei var. rhamnosus chez une malade leucemique en aplasie ayant subi une decontamination intestinale et une antibiotherapie inadaptee. La presence dans les selles de la malade d'un germe ayant exactement les memes caracteres bacteriologiques rend tres vraisemblable une translocation du tube digestif vers la circulation sanguine.

Objectif Decrire la prise en charge diagnostique, therapeutique et le pronostic a un an des osteites du pied chez les patients diabetiques au CHU de Brestentre 2006 et 2008. Materiels et methodes Etude retrospective de 31 infections osseuses concernant 20 patients. Le diagnostic d’osteite est base sur l’existence de criteres cliniques d’infection associes a – des criteres bacteriologiques d’infection (prelevements osseux et/ou cutanes et/ou hemocultures) – et/ou des criteres radiologiques d’infection osseuse. Un echec est defini par l’absence de cicatrisation de la plaie un an apres la fin de l’antibiotherapie ou par une amputation quelque soit son niveau. La guerison est definie par l’absence d’echec 1 an apres la fin de l’antibiotherapie Resultats L’âge moyen est de 65,6 ans. La duree moyenne du diabete est de 17,2 ans. Un contact osseux, un mal perforant plantaire et une collection sont retrouves dans respectivement 48,4 %, 54,8 % et 32,3 % des cas. Sur les prelevements (27 osseux, 24 cutanes et 4 hemocultures), les cocci a Gram positif sont retrouves dans 61,4 % des cas dont 43,9 % de staphylocoques (7 % de SARM) et les bacilles a gram negatif dans 33,3 % des cas. Aucune bacterie anaerobie n’est retrouvee. Une antibiotherapie est instauree pour 30 osteites. 19 actes chirurgicaux orthopediques sont realises (4 actes de mise a plat et 15 amputations). Une chirurgie vasculaire est realisee dans 4 cas. Un an apres l’arret des antibiotiques, 12 osteites sont considerees gueries Conclusion Les caracteristiques generales et la repartition des micro-organismes sont semblables a celles rapportees dans la litterature avec cependant un pourcentage de SARM et de bacteries anaerobies inferieur. L’utilisation d’un milieu de transport (Rosenow) devrait ameliorer la detection de ces dernieres. Si les amputations dites mineures font partie de la guerison, comme souvent dans la litterature, notre taux de guerison s’eleve de 39 a 68 %.

A splenectomized three-year-old developed fulminant pneumococcal septicemia despite immunization and chemoprophylaxis. The course was rapidly fatal. Fulminant pneumococcal septicemia mainly affects splenectomized individuals and is associated with very substantial mortality. Immunization prior to splenectomy and daily prophylactic oral penicillin have partial preventive efficacy. Other useful measures include carrying a health status card and inpatient antimicrobial therapy in the event of fever. The need for these precautions should be repeatedly discussed with the child's parents and physician.

In order to define the value of antibiotic prophylaxis, we conducted a prospective, randomised, double-blind, placebo-controlled study in 61 patients undergoing transurethral resection (TUR) of a bladder lesion suspected to be neoplastic. 32 patients received a single dose of 800 mg of pefloxacin at the time of anaesthetic induction and 29 patients received placebo. All patients had sterile preoperative urine and none had received any antibiotics during the fortnight preceding the operation. 3 patients in the pefloxacin group (9.4%) developed postoperative bacteriuria versus 7 in the placebo group (24.1%) (no statistically significant difference). No patient developed symptomatic urinary tract infection. We conclude that antibiotic prophylaxis is not indicated during TUR for bladder tumours.

A case is reported of an 18-year-old male patient who had a road traffic accident, with head and chest injuries. The patient was admitted to the surgical intensive care unit 24 h later because of an alteration of his level of consciousness. He required artificial ventilation. Five days later, he developed right-sided lower lobe pneumonia, treated with positive end-expiratory pressure. A Gram negative organism was found on bronchial brushing, but not in haemocultures. It was identified as Pasteurella multocida, sensitive to beta-lactamines, but not to amikacin. Cefotaxime, which had been started immediately after the arrival of the Gram stain result, was continued. Artificial ventilation was discontinued on day 12, and the patient left the unit on day 15. The patient was probably a P. multocida carrier, being in close contact with animals before his accident. This bacteria is often found in infected animal bite wounds. Pneumonia due to this bacteria usually occurs in immunodepressed patients, which was not the case here.

Serologic studies and lymphocyte analysis were carried out in 29 patients with giant cell arteritis (GCA). IgA-containing circulating immune complexes (CIC) were detected in 16 GCA patients with or without polymyalgia rheumatica (55%). A significant difference was demonstrated in autologous rosette-forming cells between the patients as a whole, and matched controls (8.6 +/- 2.0 vs 11.6 +/- 2.4, p less than 0.001), and also between patients with and patients without CIC (7.9 +/- 1.6 vs 9.4 +/- 2.0, p less than 0.001).

Immunity-linked cells include the lymphocytes and phagocytes. The former can be counted by the rosette techniques or by monoclonal antibodies, while for the latter their function is determined mainly. Good correction has been demonstrated, for example, between the number of so-called E active rosettes and both tumor extension and patient survival. The surgical act itself exaggerates the satellite anomalies of the cancer, but in any case it is followed by immunotherapy which justifies a second application of immunologic techniques.

Blood T lymphocyte subpopulations were studied by using various monoclonal antibodies in 20 patients with ankylosing spondylitis (AS) and in 20 age and sex matched controls. A significant decrease in OKT4 (p less than 0.04) and OKT8 (p less than 0.02) lymphocytes was demonstrated in AS patients. OKT4 cells were significantly decreased (p less than 0.02) in patients with a severe ankylosis and in those with the longest disease duration. This decrease was not explained by older ages. Thus there was an negative correlation between OKT4 cell ratio and disease duration. No modification in T cell subpopulations was noted when considering HLA B27 positivity or disease activity.

- Abstract
The choice of the best probabilistic postoperative antibiotics in bone and joint infections (BJIs) is still challenging. Since the implementation of protocolized postoperative linezolid in six French referral centers, linezolid-resistant multidrug-resistant Staphylococcus epidermidis (LR-MDRSE) strains were isolated in patients with BJI. We aimed here to describe clinical, microbiological, and molecular patterns associated with these strains. All patients with at least one intraoperative specimen positive for LR-MDRSE between 2015 and 2020 were included in this retrospective multicenter study. Clinical presentation, management, and outcome were described. LR-MDRSE strains were investigated by MIC determination for linezolid and other anti-MRSA antibiotics, characterization of genetic determinants of resistance, and phylogenetic analysis. Forty-six patients (colonization n = 10, infection n = 36) were included in five centers, 45 had prior exposure to linezolid, 33 had foreign devices. Clinical success was achieved for 26/36 patients. Incidence of LR-MDRSE increased over the study period. One hundred percent of the strains were resistant to oxazolidinones, gentamicin, clindamycin, ofloxacin, rifampicin, ceftaroline, and ceftobiprole, and susceptible to cyclins, daptomycin, and dalbavancin. Susceptibility to delafloxacin was bimodal. Molecular analysis was performed for 44 strains, and the main mutation conferring linezolid resistance was the 23S rRNA G2576T mutation. All strains belonged to the sequence type ST2 or its clonal complex, and phylogenetic analysis showed emergence of five populations corresponding geographically to the centers. We showed the emergence of new clonal populations of highly linezolid-resistant S. epidermidis in BJIs. Identifying patients at risk for LR-MDRSE acquisition and proposing alternatives to systematic postoperative linezolid use are essential. IMPORTANCE The manuscript describes the emergence of clonal linezolid-resistant strains of Staphylococcus epidermidis (LR-MDRSE) isolated from patients presenting with bone and joint infections. Incidence of LR-MDRSE increased over the study period. All strains were highly resistant to oxazolidinones, gentamicin, clindamycin, ofloxacin, rifampicin, ceftaroline, and ceftobiprole, but were susceptible to cyclins, daptomycin, and dalbavancin. Susceptibility to delafloxacin was bimodal. The main mutation conferring linezolid resistance was the 23S rRNA G2576T mutation. All strains belonged to the sequence type ST2 or its clonal complex, and phylogenetic analysis showed emergence of five populations corresponding geographically to the centers. LR-MDRSE bone and joint infections seem to be accompanied by an overall poor prognosis related to comorbidities and therapeutic issues. Identifying patients at risk for LR-MDRSE acquisition and proposing alternatives to systematic postoperative linezolid use become essential, with a preference for parenteral drugs such as lipopeptids or lipoglycopeptids., Competing Interests: The authors declare no conflict of interest.

- Abstract
Objectives: To describe a novel plasmid-borne class D carbapenemase (CHDL) named OXA-427 identified in several Enterobacteriaceae clinical isolates from nine patients in one Belgian hospital., Methods: OXA-427-producing isolates were analysed by an electrochemical imipenem hydrolysis method (BYG Carba test), Carba NP test, conventional phenotypic assays and by molecular methods (PCR, whole sequencing of the OXA-427-encoding plasmid and cloning). The antimicrobial resistance profile of OXA-427 was analysed by expression of the cloned gene in Escherichia coli DH10B and J53., Results: Eleven OXA-427-producing Enterobacteriaceae isolates of various species were identified from clinical specimens of nine patients between March 2012 and June 2014. OXA-427 shares only 22%-29% amino acid identity with OXA-48-like enzymes and other acquired CHDL (e.g. OXA-23, -24/40 and -58 of Acinetobacter spp.). Conversely, it appeared closely related to the chromosomal class D β-lactamase of Aeromonas media, Aeromonas hydrophila and Aeromonas sobria (99%, 89% and 77% of identity, respectively). When expressed in E. coli, OXA-427 hydrolysed imipenem and conferred resistance to extended-spectrum cephalosporins (mostly ceftazidime), penicillins including temocillin, and reduced susceptibility to carbapenems. The blaOXA-427 gene was located in a 45 kb resistance island on a 177 kb IncA/C plasmid., Conclusions: OXA-427 is a novel CHDL most closely related to chromosomal class D β-lactamase of A. media WS. It confers resistance to penicillins, ceftazidime and aztreonam and in some instances to carbapenems. OXA-427, which is not detectable by classical molecular tests, caused a protracted outbreak in one university hospital over a 2 year period., (© The Author 2017.

- Abstract
Background: Systematic seasonal bias may confound efforts to estimate usual dietary intake and diet quality. Little is known about dietary quality over the winter holiday season., Objectives: The aims of this study were to test for differences in intakes of energy, percentage of energy from macronutrients, fruits and vegetables, and diet quality measured using the Healthy Eating Index 2010 (HEI-2010) by calendar and winter holiday seasons., Design: Longitudinal cohort design., Participants/setting: Data were derived from the Life in All Seasons study. Two cohorts of women aged 40 to 60 years (N=52) from the greater Grand Forks, ND, area were followed for 1 year each between July 2012 and July 2014. Each woman completed an online diet recall using the Automated Self-Administered 24-Hour Recall every 10 days during the year, with a 92% response rate., Statistical Analyses: Effects of calendar and winter holiday seasons on intakes of energy, percent energy from macronutrients, HEI-2010 total and component scores, and grams per day of individual fruits and vegetables were tested using mixed linear models., Results: The mean total HEI-2010 score was 60.1±1.4. There were seasonal differences in some HEI-2010 component scores, but not in total scores. More lettuce or mixed lettuce salad was consumed during summer than during winter (P=0.034), and more fresh tomatoes were consumed during summer and fall compared with winter (P=0.001). More corn, berries, peaches and nectarines, and melons (P<0.001) were consumed during summer. There was no seasonal difference in reported intakes of energy (P=0.793). The total HEI-2010 score for dietary intake observed over the winter holiday season was lower than the rest of the year (P<0.001). Reported energy intake was not different (P=0.228)., Conclusions: In this population, diet quality is significantly lower during the winter holiday period, but mostly consistent by season. Multiple recalls in any season can give a reasonable representation of usual overall diet quality throughout the year., (Copyright © 2016 Academy of Nutrition and Dietetics.

- Abstract
There is no standard method for the diagnosis of prosthetic joint infection (PJI). The contribution of 16S rRNA gene PCR sequencing on a routine basis remains to be defined. We performed a prospective multicenter study to assess the contributions of 16S rRNA gene assays in PJI diagnosis. Over a 2-year period, all patients suspected to have PJIs and a few uninfected patients undergoing primary arthroplasty (control group) were included. Five perioperative samples per patient were collected for culture and 16S rRNA gene PCR sequencing and one for histological examination. Three multicenter quality control assays were performed with both DNA extracts and crushed samples. The diagnosis of PJI was based on clinical, bacteriological, and histological criteria, according to Infectious Diseases Society of America guidelines. A molecular diagnosis was modeled on the bacteriological criterion (≥ 1 positive sample for strict pathogens and ≥ 2 for commensal skin flora). Molecular data were analyzed according to the diagnosis of PJI. Between December 2010 and March 2012, 264 suspected cases of PJI and 35 control cases were included. PJI was confirmed in 215/264 suspected cases, 192 (89%) with a bacteriological criterion. The PJIs were monomicrobial (163 cases [85%]; staphylococci, n = 108; streptococci, n = 22; Gram-negative bacilli, n = 16; anaerobes, n = 13; others, n = 4) or polymicrobial (29 cases [15%]). The molecular diagnosis was positive in 151/215 confirmed cases of PJI (143 cases with bacteriological PJI documentation and 8 treated cases without bacteriological documentation) and in 2/49 cases without confirmed PJI (sensitivity, 73.3%; specificity, 95.5%). The 16S rRNA gene PCR assay showed a lack of sensitivity in the diagnosis of PJI on a multicenter routine basis., (Copyright © 2014, American Society for Microbiology. All Rights Reserved.)

- Abstract
Gait and balance disorders unresponsive to dopaminergic drugs in Parkinson's disease (PD) are secondary to lesions located outside the dopaminergic system. However, available animal models of PD fail to display l-3,4-dihydroxyphenylalanine (DOPA)-responsive parkinsonism and drug-resistant gait and balance disorders, and this lack of appropriate model could account for the deficit of efficient treatments. Because the pedunculopontine nucleus (PPN) plays an important role in locomotion control, we conducted the present study to investigate the consequences of combined dopaminergic and PPN lesions in a same animal. We used macaques that received first 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) intoxication to render them parkinsonian and then local stereotaxic lesion of the PPN. Adding bilateral PPN lesions in MPTP-lesioned macaques induced dopamine-resistant gait and balance disorders but unexpectedly improved hypokinesia. Additional MPTP injections resulted in the association of a severe DOPA-responsive parkinsonism together with DOPA-unresponsive gait disorders. Histological examination assessed a severe dopaminergic degeneration and a significant loss of PPN cholinergic neurons. We observed similar results in aged monkeys intoxicated with MPTP: they developed severe DOPA-responsive hypokinesia and tremor together with unresponsive gait and balance disorders and displayed dopaminergic lesion and a weak but significant cholinergic PPN lesion. Our results highlight the complex role of the cholinergic PPN neurons in the pathophysiology of PD because its lesion induces a dual effect with an improvement of hypokinesia contrasting with a worsening of DOPA-unresponsive gait and balance disorders. Thus, we obtained a primate model of PD that could be useful to test symptomatic treatments for these heavily disabling symptoms.

- Abstract
Introduction: We had for aim to describe control and investigation of an outbreak caused by a strain of Extended spectrum beta-lactamase producing Klebsiella pneumoniae in intensive care units of the Brest teaching hospital., Patients and Method: The case definition was a patient infected by or carrying the epidemic strain. Control measures and investigations are presented. A case-control study was conducted in the surgical intensive care unit. Each case was matched with two controls based on admission times in the unit. The study focused on diagnostic and therapeutic procedures, and potential contacts with healthcare workers, in this context of cross transmission., Results: Between February and May 2011, nine cases were reported in the surgical ICU and two in the medical ICU. Eighteen controls were matched with the nine surgical ICU cases. Several factors were found to be statistically associated with infection or colonization by the epidemic strain: the surgical block in which patients had been operated and the ward of first hospitalization; the number of trans-esophageal and trans-thoracic echocardiographies, of central venous catheter insertions, and of surgical operations; intubation. The total number of invasive procedures was also found to be statistically higher among cases., Conclusion: This study identified factors associated with colonization or infection by the epidemic strain. These factors might have been involved in the transmission tree, and be vulnerable elements for the prevention of nosocomial infections and colonisations, and their epidemic spread., (Copyright © 2012 Elsevier Masson SAS.

- Abstract
Escherichia coli isolate MEV, responsible for a bloodstream infection, was resistant to penicillins, cephalosporins, and ertapenem. Molecular and biochemical characterization revealed the production of a novel, chromosome-borne, extended-spectrum AmpC (ESAC) β-lactamase with a Ser-282 duplication and increased carbapenemase activity. This study demonstrates for the first time that chromosome-borne ESAC β-lactamases can contribute to the emergence of ertapenem resistance in E. coli clinical isolates.

- Abstract
Objectives: The study objectives were to describe the investigation and management of an imipenem-resistant Acinetobacter baumannii outbreak that occurred in the 15-bed ICU of a tertiary care teaching hospital (Brest, France), during the summer 2008., Patients and Methods: Patients harboring an imipenem-resistant A. baumannii strain were defined as case patients. We described case occurrence and steps taken to control the outbreak: contact isolation, reinforcement of hygiene procedures, unit shutdown decision, unit disinfection, and reopening. We also made a case control study and a cost analysis of the outbreak management., Results: During a 10-day period, five patients were positive for a single clone of imipenem-resistant oxa-23 A. baumannii. Four patients presented with ventilation-acquired pneumonia and one was asymptomatic. The first two patients died one day after the first swab which led to the identification of A. baumannii. No additional case was noted in the ICU or in other hospital units after deciding to close the ICU. The cost of outbreak management was estimated at 264,553 euros. The case control study identified several factors associated with infection or colonization: length of stay in the ICU, chronic respiratory disease, number of previous antibiotic classes used, duration of ventilation, prone position, echocardiography, and presence of a nasogastric tube., Conclusion: This outbreak occurred during the summer period requiring the shutdown of the ICU and inducing a considerable cost. Rapid reactions of the ICU staff during the outbreak enabled to limit the epidemic., (Copyright © 2011 Elsevier Masson SAS. All rights reserved.)

- Abstract
Unlabelled: The fight against healthcare-associated infections is based on preventive measures of multidrug resistant bacteria diffusion. Hand hygiene is the simplest and the most effective preventive measure to reduce cross-transmission of infectious agents. Hydroalcoholic solutions for hand hygiene was recently introduced in the University Hospital of Brest (France). The aims of the study were: to describe the epidemiology of healthcare-associated infections due to methicillin-resistant Staphylococcus aureus (MRSA); to determine the annual consumptions of antistaphylococcal antibiotics; and to discuss the relation between consumption of antiseptic products or antibiotics and the epidemiology of MRSA., Methods: A retrospective epidemiological and pharmaco-epidemiological study was realized from January 2004 to December 2007 in the University Hospital of Brest (France). It allowed to bring to light the cases of healthcare-associated infections due to MRSA and to quantify the consumptions of hang hygiene products and antistaphylococcal antibiotics., Results: this retrospective study showed a decrease of healthcare-associated infections due to MRSA and an increase of the consumption of hydroalcoholic solutions. Antistaphylococcal resistance rates also decreased in a context of fall of the global antibiotics consumption in the hospital., (Copyright © 2011 Elsevier Masson SAS. All rights reserved.)

- Abstract
The aim of this study was to characterize the resistance mechanisms of two strains of Staphylococcus aureus UCN42 and UCN43 isolated from cystic fibrosis patients that displayed an unusual phenotype of resistance to macrolides. The strains were resistant to erythromycin and the 16-membered macrolide spiramycin but susceptible to clindamycin. None of the strains contained erm or msr(A) genes by PCR. Sequencing of genes encoding ribosomal targets of macrolides revealed mutations in conserved regions of the L4 ribosomal protein, a R168S mutation for S. aureus UCN43 and mutations at positions G69A and T70P for both strains. This observation extends previous reports of similar mutations in streptococci and mycoplasma to S. aureus.

- Abstract
This study presents an analysis of the distribution and organization pattern of axons originating from the substantia nigra pars reticulata and projecting to the thalamus in monkeys. Biotin dextran amine was iontophoretically injected into different parts of the substantia nigra pars reticulata of monkeys (African green monkeys and macaques). In whatever part of the substantia nigra the injection was made, numerous axonal endings were found to be distributed within different thalamic regions: the ventral anterior nucleus and mainly its magnocellular part, the most ventromedial part of the ventral lateral nucleus, and the mediodorsal and parafascicular nuclei. Moreover, the nigrothalamic projection appeared to be topographically organized. Ten anterogradely labeled axons were reconstructed from serial sections. The axons terminated in three to six terminal fields per axon located in a relatively small portion of only one thalamic region. These terminal fields were variable in size and comprised 4-43 very thin, varicose branches. They consisted either of different axonal branches of the same axon or of different axons and covered 10-31 thalamic cell bodies. These findings demonstrate that the overall morphological organization of individual nigral axons is complex and allows single axons to influence thalamic neurons via a combination of divergent, convergent, and amplification processes., (Copyright 2002 Wiley-Liss, Inc.)

- Abstract
The existence of a dopaminergic innervation of the subthalamic nucleus (STN) has been demonstrated in rats but has remained controversial in primates. The aim of the present study was first to demonstrate the existence of a dopaminergic innervation of the STN in monkeys using tracing methods and then to quantify the loss of dopaminergic fibers in the parkinsonian state in monkeys and humans. Following injection of Fluoro-Gold into the STN of a vervet monkey (Cercopithecus aethiops), retrogradely labeled neurons were found to be scattered in all dopaminergic areas of the mesencephalon. Injection of biotin dextran amine into dopaminergic areas A8 and A9 of two monkeys resulted in anterogradely labeled axons located throughout the whole extent of the STN. Labeled axons that also expressed tyrosine hydroxylase (TH) were reconstructed from serial sections. Some terminal axonal arborizations had profuse branching and occupied much of the STN, and others were restricted to small portions of the nucleus. In TH-immunoreactive sections, numerous sparse, fine, and varicose TH-positive fibers were observed in the STN of normal monkeys and humans. Quantification of these TH-positive fibers revealed a 51% loss of TH-positive fibers in MPTP-intoxicated monkeys and a 65% loss in Parkinson's disease patients compared with their respective controls. These findings demonstrate the existence of a dopaminergic innervation of the STN in primates. The loss of dopaminergic innervation in MPTP-intoxicated monkeys and in Parkinson's disease patients may directly affect the activity of STN neurons and could participate in the hyperactivity of the structure., (Copyright 2000 Wiley-Liss, Inc.)

- Abstract
A splenectomized three-year-old developed fulminant pneumococcal septicemia despite immunization and chemoprophylaxis. The course was rapidly fatal. Fulminant pneumococcal septicemia mainly affects splenectomized individuals and is associated with very substantial mortality. Immunization prior to splenectomy and daily prophylactic oral penicillin have partial preventive efficacy. Other useful measures include carrying a health status card and inpatient antimicrobial therapy in the event of fever. The need for these precautions should be repeatedly discussed with the child's parents and physician.

- Abstract
In order to define the value of antibiotic prophylaxis, we conducted a prospective, randomised, double-blind, placebo-controlled study in 61 patients undergoing transurethral resection (TUR) of a bladder lesion suspected to be neoplastic. 32 patients received a single dose of 800 mg of pefloxacin at the time of anaesthetic induction and 29 patients received placebo. All patients had sterile preoperative urine and none had received any antibiotics during the fortnight preceding the operation. 3 patients in the pefloxacin group (9.4%) developed postoperative bacteriuria versus 7 in the placebo group (24.1%) (no statistically significant difference). No patient developed symptomatic urinary tract infection. We conclude that antibiotic prophylaxis is not indicated during TUR for bladder tumours.
