Introduction : Instaure au niveau national depuis 2018, le Service sanitaire des etudiants en sante (SSES) vise a les former a mener des actions d’education pour la sante.Methode et resultats : Un dispositif pedagogique d’une duree equivalente a six semaines a temps plein a ete mis en place en troisieme annee de medecine a Rennes (35). L’objectif est que les etudiants developpent les competences necessaires pour mener des interventions fondees sur une demarche projet, aupres de publics varies, sur des themes prioritaires de sante publique.De nouvelles approches pedagogiques ont ete developpees pour integrer au cursus medical l’apprentissage de la promotion et de l’education pour la sante. Des innovations ont ete mises en place : travail sur la posture educative, tutorat des etudiants de troisieme annee par des internes en medecine, forum de simulation des actions concretes sous la supervision d’une double expertise thematique et populationnelle. Au-dela de l’acquisition de competences en education pour la sante, la formation vise a susciter une demarche reflexive et s’appuie sur l’education par les pairs.Les 240 etudiants de la faculte preparent en trinome leur projet tout au long de l’annee universitaire. Leurs actions se deroulent sur une plage de dix demi-journees aupres d’une centaine d’etablissements, dans la diversite des territoires de la subdivision. Elles permettent d’intervenir aupres d’environ 10 000 personnes par an.Discussion : L’education et la promotion de la sante occupent desormais une place centrale dans la formation des etudiants de troisieme annee, condition indispensable pour amorcer l’acquisition durable de ce champ de competences par les futurs professionnels de sante.

International audience; BACKGROUND: In developed countries, about 15% of women are occupationally exposed to solvents. Associations between this maternal occupational exposure and intrauterine fetal growth are inconsistent, but almost no existing study has investigated this relation by solvent family (oxygenated, petroleum, and chlorinated), although they may affect fetal growth differently. OBJECTIVES: To investigate the relations between maternal occupational solvent exposure, by solvent family, and the risk of neonates born small for gestational age (SGA), or with low birthweight, or with small head circumference (HC). METHODS: Among the 18,040 women included in the Elfe birth cohort, we included 13,026 women who worked during pregnancy (72% of the cohort). Information about maternal occupations and industrial activities during pregnancy was collected by questionnaire at the maternity ward, and completed at 2-month when necessary. Using Matgéné job-exposure matrices, we assessed maternal occupational exposure to solvents. Logistic and multiple linear regressions were used to assess the association between maternal occupational solvent exposure and SGA status, birth weight, and HC. Analyses were conducted for exposure during pregnancy and also stratified by the trimester that pregnancy leave began. RESULTS: We observed a higher risk of SGA newborns among mothers occupationally exposed during pregnancy to petroleum solvents (OR(adjusted) = 1.26; 95%CI: 1.01 to 1.57). Among women working until the third trimester of pregnancy, we observed a higher risk of SGA newborns to those occupationally exposed to oxygenated solvents (OR(adjusted) = 1.75; 95%CI: 1.11 to 2.75), a significantly lower birthweight for infants of mothers exposed to petroleum solvents (β(adjusted) = -47.37 g; -89.33 to -5.42), and a lower HC among newborns of those occupationally exposed to oxygenated solvents (β(adjusted) = -0.28; -0.49 to -0.07) and to chlorinated solvents (β(adjusted) = -0.29; -0.53 to -0.05). DISCUSSION: Our results suggest that maternal occupational solvent exposure may influence fetal growth, especially exposure into the third trimester of pregnancy.

Background and purpose To compare the accuracy and utility of contrast enhanced magnetic resonance angiography (MRA) (CEMRA) to Time of Flight MRA (TOF MRA) during detection and evaluation of occlusions on patients diagnosed with acute ischemic stroke (AIS). Methods This single-center study was approved by our local institutional research ethics board. From August 2014 to July 2016, 131 consecutive adult patients with confirmed AIS were included. Detection of an arterial occlusion and its characterization were evaluated independently with CEMRA or TOF MRA by two blinded neuroradiologists, then by consensus using all available MR sequences. A Cohen's Kappa coefficient (κ) and intra-class correlation coefficients (ICC) were used to compare the two techniques. Results There was substantial concordance in the detection of arterial occlusion between CEMRA and TOF MRA (κ = 0.75). TOF MRA was more likely to show an arterial occlusion than CEMRA (63 versus 52 patients respectively). There were 13 and 1 false positive arterial occlusion with TOF MRA and CEMRA respectively, and 1 false negative with TOF MRA. There was excellent concordance between the location of arterial occlusions and CEMRA and TOF MRA [κ = 0.89 (0.72–0.97)]. CEMRA was significantly more likely to allow measurement of the thrombus than was TOF MRA [38 (75%) versus 14 (22%)] (P Conclusions Our study showed that CEMRA imaging detected arterial occlusions better than TOF MRA in AIS patients and more precisely such that thrombus length and location could be known, which improves the patient's management and care.

A recent treatment algorithm suggests that proximal anterior cruciate ligament (ACL) tears with good-to-excellent tissue quality are amenable to primary repair. Our primary objective was to assess the ability of MRI to determine the exact tear location and tissue quality, using arthroscopy as a reference standard. In an initial sample of 71 patients with prior ACL surgery (repair or reconstruction), the diagnostic accuracy of MRI was assessed using arthroscopy as a reference standard. Each native ACL tear was graded according to Sherman’s arthroscopic classifications during the surgical procedure. MRI scans were retrospectively reviewed for grading, blinded to arthroscopic findings and in consensus by two musculoskeletal radiologists. Tear location and tissue quality were graded using the MRI Sherman tear location (MSTL), MRI Sherman tissue quality (MSTQ) and simplified MRI Sherman tissue quality (S-MSTQ) classifications. Intra- and inter-observer agreement was assessed on a second sample of 77 patients. MRI classification accuracy was compared by McNemar’s tests. Intra- and inter-observer agreement was assessed using Cohen’s kappa coefficient. Regarding tear location, diagnostic accuracy was 70% (50/71) based on the MSTL classification. Diagnostic accuracy for tissue quality was 52% (15/29) based on the MSTQ classification and 90% (26/29) for the S-MSTQ classification (p = 0.003). Inter-observer agreement was good for MSTL (κ = 0.78) and moderate-to-good for the MSTQ and S-MSTQ classifications (κ = 0.44 and 0.63 respectively). MRI seems to be accurate in assessing tear location and tissue quality and may help clinicians to predict the reparability of ACL tears. • MRI seems to be accurate in assessing tear location and tissue quality and may help clinicians to predict the reparability of ACL tears. • High intra-observer agreement was demonstrated when grading the tear location into one of five types. • The diagnostic accuracy of the simplified MRI tissue quality classification, involving deletion of the ligament stump signal criterion, was better than that observed with the MRI Sherman tissue quality classification, but was moderate to good in terms of inter- and intra-observer agreement.

International audience; Objectives: People at risk of chronic obstructive pulmonary disease (COPD) can benefit from appropriate medical management before severe symptoms appear. This study assesses the value of the COPD Assessment Test (CAT) questionnaire for screening dairy farmers, who tend to be slow or reluctant to seek health care.Methods: During the time period 2012-2017, 2089 randomly selected dairy farmers in Brittany (France) were invited to complete self-administered questionnaires (including the CAT) and to undergo an occupational health check-up using an electronic mini-spirometer and conventional spirometry. Those showing symptoms suggestive of COPD and/or a ratio FEV1 /FEV6 < 80% were sent to a pulmonologist for further check-up, including spirometry with a reversibility test. Multivariate logistic models based on CAT scores and socio-demographic or work-related factors were developed to predict COPD.Results: The 1231 farmers who underwent the occupational health check-up included 1203 who met the inclusion/exclusion criteria. Pulmonologist identified 16 (1.3%) cases of COPD. A multivariate logistic regression model (covariates: CAT sum score, on-farm time, BMI, smoking status, free-stall mulching) provided an area under the receiver-operating characteristic curve (AUC) of 0.87 (95% CI: 0.75-0.98). Using a cut-off of 0.007 gave a sensitivity of 93.8%, and a specificity of 62.4%. Another model that included CAT breathlessness and the same covariates performed marginally better (AUC = 0.88, 95% CI: 0.77-0.98).Conclusion: Our predictive models can both benefit dairy farmers by providing early diagnosis and management of their COPD and avoid unnecessary, costly spirometry during screening process.

Choroidal thickness can undergo considerable variations in response to different substances. The aim of this study was to assess the change in choroidal thickness after the ingestion of taurine and caffeine contained in the Red Bull energy drink.Enhanced Depth Imaging - Spectral Domain Optical Coherence Tomography was used to measure subfoveal choroidal thickness (SFCT) variations in healthy volunteers at several time points after drinking a Red Bull can (25 cl).Forty eyes of 20 volunteers were enrolled. A significant reduction in SFCT (-14 μm, p 0.0001) occurred at 1 h after the Red Bull intake, and was even more important (-20.14 μm, p 0.0001) in eyes with particularly thick choroids (≥ 395 μm). SFCT measurements at 4 h were comparable to baseline.A concomitant ingestion of caffeine and taurine can induce a transient choroidal thinning that is more marked in eyes with thick choroids.NCT02856256.

Introduction : le tatouage de la plaque areolo-mamelonnaire (PAM) accompagne souvent la reconstruction mammaire apres chirurgie pour cancer du sein. Peu d’etudes ont evalue la satisfaction des patientes en ayant beneficie.Objectifs : evaluer la satisfaction esthetique a un an des femmes ayant beneficie de la technique de tatouage realisee par des infirmieres.Methode : 98 femmes ont ete incluses. La satisfaction globale concernant la reconstruction de la PAM et la satisfaction sur la couleur, la taille, la position et la forme ont ete evaluees a l’aide de questionnaires remplis par les patientes et par un jury professionnel.Resultats : pour 97 % des patientes, les resultats de la reconstruction de PAM etaient satisfaisants. Le taux de satisfaction concernant la couleur etait de 67 %, la taille 96 %, la forme 95 % et la position 94 %. La satisfaction du jury a propos de la reconstruction de la PAM etait de 79 %. La satisfaction sur la couleur etait de 52 %, la taille 77 %, la forme 75 % et la position 69 %.Discussion : les patientes etaient globalement satisfaites des resultats du tatouage 1 an apres et leur niveau de satisfaction est superieur a celui du jury. Seulement 6.1 % des femmes ont demande une nouvelle dermopigmentation en raison d’une decoloration.Conclusion : le tatouage de la PAM permet d’obtenir un haut niveau de satisfaction esthetique et peut etre realise en ambulatoire par une infirmiere competente.

Magnetic resonance imaging (MRI) is the diagnostic cornerstone for precisely identifying acute ischaemic strokes and locating vascular occlusions, especially since mechanical thrombectomy has become a reference treatment. We observed that a post-contrast three-dimensional turbo-spin-echo T1-weighted sequence showed striking post-contrast vascular hyperintensities (PCVH) in ischaemic territories. We aimed to evaluate the prevalence and the meaning of this finding. This retrospective single centre study included 130 consecutive patients admitted for acute ischaemic stroke with a 3-T MRI performed in the first 12 h of symptom onset from September 2014 through September 2016. Two neuroradiologists blinded to clinical data analysed the first MRI assessments. The association between PCVH and clinical, radiological and follow-up findings was assessed, as well as inter- and intra-observer agreements. Of 130 patients, 105 (81%) had PCVH in the ischaemic territory. PCVH were associated with the presence of thrombus on susceptibility weighted imaging (p < 0.0001) and vascular occlusions on MR angiography (p < 0.0001). All patients with a visible thrombus had PCVH closely surrounding the clot. PCVH were associated with higher initial (p < 0.01) and follow-up (p < 0.01) National Institutes of Health Stroke Scale score, and higher mRS score (p < 0.05). Thrombectomy was the reference treatment for all patients with arterial occlusions. Inter- and intra-observer agreements for the detection of PCVH were excellent (κ = 0.95 and κ = 0.91, respectively). PCVH during acute strokes are a striking sensitive and reproducible tool for diagnosing and locating vascular occlusions. It may help triage patients who can benefit from thrombectomy. • Post-contrast vascular hyperintensities (PCVH) are a sensitive MR finding in acute stroke • PCVH are strongly associated with the presence and location of arterial occlusions • Inter- and intra-observer agreements for the detection of PCVH are excellent • PCVH are visible even in the case of significant motion artefacts • PCVH may help triage patients who can benefit from mechanical thrombectomy

Purpose Infantile spasms (IS) can occur as the only seizure type in children with surgically amenable epilepsies. Although early surgery has shown positive effects, little is known regarding outcomes. Methods We retrospectively reviewed all children with IS referred to our tertiary center between 2002 and 2014 and try to define factors of outcome. Results Sixty-eight children with focal onset seizures were referred: twenty children with a hemispheric implication and 48 with one or more lobes involved. The age of onset was significantly earlier in the hemispheric population (8.0 versus 16.7 months in the focal population). There was no difference in the age of onset between anterior and posterior onset zones, as we could expect regarding the maturation gradient. The epilepsy began earlier in life in tuberous sclerosis than in DNET. Only three children of the 48 non-hemispheric patients had a normal MRI at the time of the surgery. Temporal lobe was involved only in a third of the population. More than 86% of the patients were operated on. Patients with hemispheric lesions were operated on younger (2.6 years+/− 2.1 years) compared to 4.6+/− 3.5 years in the whole population. The most frequent etiologies were in descending order: dysplasia, ganglioglioma or dysembryoplastic tumours and tuberous sclerosis. The global seizure outcome was favorable (Engel 1a) in 74.6% of the patients, and 87.9% if the delay between the first seizure and the surgery was less than 36 months. It fell to 64.7% if the delay exceeded 50 months. Conclusion Spasms of focal onset have a similar postsurgical outcome as other seizure types so surgery may be an excellent option for treating selected patients with focal infantile spasms. Volume and type but not topography of the lesion influence the age of onset. MRI is very helpful to locate the pathology in the pediatric population, since only a small portion had a normal MRI.

ObjectivesPrenatal occupational exposure to pesticides has been associated with male reproductive tract abnormalities. Little is known about the possible impact of non-occupational pesticide exposure on fetal and child development in the general population. Using data from a nationwide birth cohort, we aimed to assess the association between residential sources of prenatal pesticide exposure and the risks of hypospadias and cryptorchidism.MethodsOf the 9281 boys in ELFE (French Longitudinal Study of Children), the national French birth cohort, 53 were diagnosed with hypospadias and 137 with cryptorchidism. We assessed residential exposure sources from self-reported domestic use of eight types of pesticide products and French spatial land use data with acreage within a 1000 m radius around each family’s home for 21 crop types. We used logistic regression modelling, adjusted for possible confounders that included estimated dietary pesticide intake. Multiple imputations were used to handle missing data.ResultsAn increased risk of hypospadias was associated with domestic pesticide use against fleas and ticks (OR=2.28, 95% CI 1.09 to 4.75); no associations were found between cryptorchidism and any domestic pesticide use. Slightly increased risks of cryptorchidism were observed in association with all crop acreages near homes during pregnancy, especially for orchards, and no association was observed for hypospadias.ConclusionsOur results suggest a possible increased risk of hypospadias associated with prenatal use of some domestic pesticide products, likely to contain insecticides, and of cryptorchidism with nearby orchard acreage (crops repeatedly sprayed with pesticides). This work is limited by its modest number of cases.

Nipple-areolar complex tattooing often completes the breast mound reconstruction process after cancer surgery. However, there have been few studies evaluating patient satisfaction with this technique.To assess patients' esthetic satisfaction with the results of tattooing performed by nurses.Ninety-eight women participated in the study. Overall satisfaction with reconstruction and satisfaction with the tattoo's color, dimension, position, and form were determined using questionnaires completed by patients and a professional jury.97% of patients reported overall satisfaction with the results of nipple-areolar reconstruction. The satisfaction rate with the tattoo's color was 67%, with dimension 96%, with form 95%, and with position 94%. The satisfaction rates of the jury were as follows: nipple-areolar reconstruction 79%; color 52%; dimension 77%; form 75%; and position 69%.On the whole, the patients were satisfied with the results one year after tattooing and their satisfaction rate was higher than that of the jury's. Only 6.1% of women required a second tattoo because of discoloration.Nipple-areolar complex tattooing has a high rate of patient esthetic satisfaction and can be performed by a trained nurse without the need for hospital admission.

Background: A growing body of evidence suggests that prenatal exposure to pesticides might impair fetal development. Nonetheless, knowledge about pesticide exposure of pregnant women, especially in Europe, is largely restricted to a limited panel of molecules. Aim: To characterize the concentration of 140 pesticides and metabolites in hair strands from women in the ELFE French nationwide birth cohort. Methods: Among cohort members who gave birth in northeastern and southwestern France in 2011, we selected those with a sufficient available mass of hair (n = 311). Bundles of hair 9 cm long were collected at delivery. We screened 111 pesticides and 29 metabolites, including 112 selected a priori based on their reported usage or detection in the French environment. The bundles of hair from 47 women were split into three segments to explore the intraindividual variability of the exposure. Intraclass correlation coefficients (ICCs) were computed for the chemicals with a detection frequency >70%. Results: We detected a median of 43 chemicals per woman (IQR 38–47). Overall, 122 chemicals (>20 chemical families) were detected at least once, including 28 chemicals detected in 70–100% of hair samples. The highest median concentrations were observed for permethrin (median: 37.9 pg/mg of hair), p-nitrophenol (13.2 pg/mg), and pentachlorophenol (10.0 pg/mg). The ICCs for the 28 chemicals studied ranged from 0.59 to 0.94. Conclusion: Pregnant women are exposed to multiple pesticides simultaneously from various chemical families, including chemicals suspected to be reproductive toxicants or endocrine disruptors. The ICCs suggest that the intraindividual variability of pesticide concentrations in hair is lower than its interindividual variability.

BACKGROUND AND PURPOSE: MR imaging is the key examination in the follow-up of patients with MS, by identification of new high-signal T2 brain lesions. However, identifying new lesions when scrolling through 2 follow-up MR images can be difficult and time-consuming. Our aim was to compare an automated coregistration-fusion reading approach with the standard approach by identifying new high-signal T2 brain lesions in patients with multiple sclerosis during follow-up MR imaging. MATERIALS AND METHODS: This prospective monocenter study included 94 patients (mean age, 38.9 years) treated for MS with dimethyl fumarate from January 2014 to August 2016. One senior neuroradiologist and 1 junior radiologist checked for new high-signal T2 brain lesions, independently analyzing blinded image datasets with automated coregistration-fusion or the standard scroll-through approach with a 3-week delay between the 2 readings. A consensus reading with a second senior neuroradiologist served as a criterion standard for analyses. A Poisson regression and logistic and γ regressions were used to compare the 2 methods. Intra- and interobserver agreement was assessed by the κ coefficient. RESULTS: There were significantly more new high-signal T2 lesions per patient detected with the coregistration-fusion method (7 versus 4, P < .001). The coregistration-fusion method detected significantly more patients with at least 1 new high-signal T2 lesion (59% versus 46%, P = .02) and was associated with significantly faster overall reading time (86 seconds faster, P < .001) and higher reader confidence (91% versus 40%, P < 1 × 10(−4)). Inter- and intraobserver agreement was excellent for counting new high-signal T2 lesions. CONCLUSIONS: Our study showed that an automated coregistration-fusion method was more sensitive for detecting new high-signal T2 lesions in patients with MS and reducing reading time. This method could help to improve follow-up care.

To evaluate the prevalence of cerebral remote microhaemorrhages (RMH) and remote haematomas (RH) using magnetic resonance susceptibility-weighted imaging (SWI) among patients treated for gliomas during follow-up. We conducted a retrospective single centre longitudinal study on 58 consecutive patients treated for gliomas from January 2009 through December 2010. Our institutional review board approved this study. We evaluated the presence and number of RMH and RH found outside the brain tumour on follow-up MR imaging. We performed univariate and bivariate analyses to identify predictors for RMH and RH and Kaplan–Meier survival analysis techniques. Twenty-five (43%) and four patients (7%) developed at least one RMH or RH, respectively, during follow-up. The risk was significantly higher for patients who received radiation therapy (49% and 8% versus 0%) (p = 0.02). The risk of developing RH was significantly higher in patients with at least one RMH and a high burden of RMH. The mean age of those presenting with at least one RMH or RH was significantly lower. RMH were common in adult survivors of gliomas who received radiation therapy and may predict the onset of RH during follow-up, mainly in younger patients. • Brain RMH and RH are significantly more likely to occur after RT. • RMH occur in almost half of the patients treated with RT. • RMH and RH are significantly more frequent in younger patients. • RH occur only in patients with RMH.

Objectives This study was undertaken to analyze prosthetic joint infection (PJI)-causing microorganisms and compare their distribution patterns according to PJI classification. Methods Cohort study from a single referral center for bone-and-joint infections from January 2004 to December 2015. Results Nine hundred and twenty-six patients, who developed 997 PJIs, involving the hip (62%), knee (35%) and/or shoulder (1%), were included. PJIs were classified as early postoperative (19%), late chronic (30%), hematogenous (35%) and undetermined (16%). Pathogens most frequently isolated from early-postoperative PJIs were staphylococci (57%), with 25% each Staphylococcus aureus or Staphylococcus epidermidis ; 21% were polymicrobial and 10% Gram-negative rods. For late-chronic PJIs, the most frequent microbes were staphylococci (61%), predominantly S. epidermidis (35%); anaerobic bacteria were isolated from 15%; 11% were polymicrobial. Hematogenous PJIs were 99% monomicrobial. Although S. aureus was the most frequently isolated species (28%), streptococci were isolated slightly more often than staphylococci (39% vs. 36%). Among streptococci, group B streptococci were the most frequent (15%). The portal of entry was identified for 52% of hematogenous PJIs: 15% cutaneous, 11% dental, 9% gastrointestinal, 6% urinary, and 11% miscellaneous. Conclusion Although a wide variety of microorganisms was isolated from PJIs, specific microbiological patterns were observed according to infection classification.

L’objectif principal de ce travail etait de decrire la population des patients transfuses en prehospitalier au CHU de Rennes de 2011 a 2017, l’objectif secondaire etait de mesurer l’impact de la mise en œuvre d’actions de sensibilisation des prescripteurs a partir de 2015. Methode Il s’agit d’une etude descriptive retrospective monocentrique a partir des donnees des patients transfuses issues des dossiers de regulation SAMU, des feuilles d’intervention SMUR, du dossier medical informatise et des feuilles de surveillance du dechoquage (SAUV). Les analyses statistiques ont ete realisees avec le logiciel R version 3.4.2. Resultats Trois cent soixante-cinq CGR ont ete transfuses a 173 patients par le SMUR en sept ans. Les principales caracteristiques de la population totale sont presentees dans le Tableau 1 . Les principaux motifs d’appel etaient l’hemorragie digestive (HD) (38 %), l’AVP (25 %) et la plaie vasculaire (10 %). Le ratio H/F = 73 %. En prehospitalier, 30 % des patients ont recu des amines, 23 % de l’exacyl, 18 % ont beneficie de moyens hemostatiques et 6 % sont decedes sur place. 88 % ont ete admis au SAUV et 6 % directement au bloc operatoire. Quatorze pour cent sont decedes au SAUV. Le taux de deces a 30 jours a ete de 24 % (2016–2017). Entre les deux periodes, aucune difference significative n’a ete constatee concernant le profil des patients transfuses (âge, lieu d’intervention, motif de transfusion ou presence de facteurs aggravants). Deux variables ont presente une evolution significative : augmentation du nombre de patients transfuses rapporte au nombre de sorties (0,74 % en 2016–2017 vs 0,47 % en 2011–2015) et du taux d’utilisation d’acide tranexamique (34,7 % vs 13 %). Conclusion L’hemorragie digestive est le motif principal de transfusion. La prise en charge des chocs hemorragiques au SMUR a evolue entre les periodes 2011–2015 et 2016–2017. On transfuse plus de patients et l’acide tranexamique est plus utilise. Cette etude est limitee par le defaut de tracabilite des actes realises.

Objectifs Comparer une methode automatisee de lecture en Coregistration-Fusion (CF) avec la methode standard de detection de nouvelles lesions cerebrales en hypersignal T2 (HST2) chez des patients atteints de sclerose en plaques (SEP) au cours de leur suivi. Materiels et methodes Cette etude monocentrique approuvee par l’IRB incluait 94 patients traites par dimethyl fumarate de janvier 2014 a aout 2016. Un neuroradiologue senior et un radiologue junior ont verifie la presence de nouvelles lesions cerebrales HST2, analysant de maniere independante les ensembles d’images en aveugles avec la CF automatisee ou la methode standard de defilement manuel. Un delai de 3 semaines entre les deux lectures etait requis. Des tests de Poisson et de Wilcoxon ont ete utilises pour comparer les deux methodes. Les accords intra et inter-observateurs ont ete evalues par le coefficient Kappa. Resultats L’âge moyen des patients etait de 38,9 ans. Il y avait significativement plus de nouvelles lesions HST2 detectees avec la methode CF (712,2 versus 47,5 p Conclusion Notre etude a montre qu’une methode CF automatisee etait considerablement plus facile et plus sensible pour detecter de nouvelles lesions HST2 chez les patients atteints de SEP, ainsi que pour reduire le temps de lecture. Cette nouvelle methode pourrait considerablement ameliorer le suivi.

Objectifs (1) etudier la reproductibilite intra et inter observateur des classifications proposees pour determiner les patients eligibles a une reparation primaire du ligament croise anterieur (LCA) ; (2) proposer et etudier la reproductibilite de classifications simplifiees pour la localisation et la qualite des tissus ; (3) correler les facteurs d’imagerie permettant aux patient de beneficier d’une reparation primaire du LCA et les constatations arthroscopiques. Materiel et methode Les IRM de 70 patients consecutifs porteurs d’une rupture complete du LCA ont ete retrospectivement relues par 2 radiologues seniors et un junior dans le but d’etudier la concordance de grading des lesions. La localisation lesionnelle etait typee selon 3 classifications et la qualite du moignon selon deux echelles differentes. Secondairement, les IRM de 100 patients traites par arthroscopie etaient analysees en consensus et confrontees aux constatations operatoires afin d’evaluer la capacite de l’IRM a predire la reparabilite du ligament. Resultats Les resultats preliminaires retrouvaient une reproductibilite (kappa) inter-operateur, de 0,774 et 0,821 pour la localisation lesionnelle et 0,243 et 0,214 pour la qualite du moignon. Conclusion L’IRM semble etre un outil performant pour aider a determiner les patients eligibles a une reparation primaire du LCA.

L’objectif de l’etude etait d’evaluer la pertinence des prescriptions de CGR realisees en 2017 et de comparer les resultats a ceux obtenus lors d’une meme evaluation en 2009. Methode Selon le type d’etablissement (ES), de 60 a 120 prescriptions realisees au cours des 6 derniers mois 2017 ont ete tirees au sort. La derniere prescription au cours de l’hospitalisation a ete analysee, afin d’eviter les situations non stabilisees. Exclusions : urgences vitales et vitales immediates, pediatrie et transfusions en HDJ. Une grille realisee a partir de celle utilisee en 2009 a permis de recueillir les donnees sur le profil du patient, le contexte et la pertinence de la prescription. Le logiciel SPHINX a ete utilise pour la saisie et l’analyse descriptive et le logiciel SPSS pour les comparaisons 2017/2009. Resultats 537 prescriptions issues de 7 ES (3 CH, 1 CHR et 3 CHU) ont ete analysees. Les principales donnees sont precisees dans Le Tableau 1 (Hb en G.dL−1). Ratio H/F = 1,4. Dans 47 % des cas, la presence ou l’absence de signes d’intolerance a l’anemie n’avait pas ete tracee. L’Hb pre-T est plus elevee en cas d’existence de facteurs limitants. Le nombre de CGR transfuses est lie au niveau d’Hb pre-T et l’Hb de sortie est plus elevee chez la femme. Les objectifs de la prescription et de la prise en charge transfusionnelle globale sont atteints respectivement dans 57 et 71 % des observations. Ils sont tres variables selon l’evaluateur et difficiles a analyser car insuffisamment definis. Les populations des 2 etudes sont comparables. Les Hb pre-T sont identiques, par contre les Hb post-T et de sortie sont plus basses, ce qui peut etre lie a l’augmentation du taux de prescription d’un seul CGR (de 10 a 34 %). Conclusion Comme en 2009, l’Hb pre-T est conforme aux recommandations. Il faut noter la prise en compte par les prescripteurs de l’interet de fractionner la delivrance des CGR afin de s’adapter aux besoins du patient en ne transfusant eventuellement qu’un seul CGR.
