Efficacy of an eradication protocol in case of Pseudomonas aeruginosa primo-infections in children with cystic fibrosis

Introduction: Patients with cystic fibrosis (CF) are more susceptible to pathogens like P. aeruginosa (PA). PA primo-­‐infections require particular attention, as with failure in eradication, there is accelerated lung deterioration. The main aim of this study is to assess the rate of PA eradication according to our particular protocol with inhaled tobramycin and oral ciprofloxacin, as there is no consensus in the literature on what eradication protocol the best is. Methods: Retrospective single centre study with data analysis from June 1st 2007 to June 1st 2011 of patients who had primo-­‐infections exclusively treated by 3 x 28 days of inhaled tobramycin and oral ciprofloxacin for the first and last 21 days. Success in eradication is defined by ≥ 3 negative bacteriologies for 6 months after the beginning of the protocol. If ≥ 1 bacteriology is positive, we consider the eradication as a failure. Results: Out of 41 patients, 18 were included in our analysis. 7 girls (38.9%) and 11 boys (61.1%) followed the eradication protocol. Boys had 12 primo-­‐infections and girls had 8. Among these 20 primo-­‐infections, 16 (80%) had an all-­‐overall success in eradication and 4 (20%) a failure. No significant statistical difference for age between these groups (t-­‐test = 0.07, p = 0.94), neither for FEV1% (t-­‐test = 0.96, p = 0.41) nor BMI (t-­‐test = 1.35, p = 0.27). Rate of success was 100% for girls and 66.6% for boys. Conclusion: Our protocol succeeded in an overall eradication rate of 80%, without statistical significant impact on FEV1 % and BMI values. However, there is a sex difference with eradication rates in girls (100%) and boys (66.6%). A sex difference has not yet been reported in the literature. This should be evaluated in further studies.

Is there an advantage to be gained from adding digital image cytometry of brush cytology to a standard biopsy protocol in patients with Barrett's esophagus?

BACKGROUND AND STUDY AIMS: The current gold standard in Barrett's esophagus monitoring consists of four-quadrant biopsies every 1-2 cm in accordance with the Seattle protocol. Adding brush cytology processed by digital image cytometry (DICM) may further increase the detection of patients with Barrett's esophagus who are at risk of neoplasia. The aim of the present study was to assess the additional diagnostic value and accuracy of DICM when added to the standard histological analysis in a cross-sectional multicenter study of patients with Barrett's esophagus in Switzerland. METHODS: One hundred sixty-four patients with Barrett's esophagus underwent 239 endoscopies with biopsy and brush cytology. DICM was carried out on 239 cytology specimens. Measures of the test accuracy of DICM (relative risk, sensitivity, specificity, likelihood ratios) were obtained by dichotomizing the histopathology results (high-grade dysplasia or adenocarcinoma vs. all others) and DICM results (aneuploidy/intermediate pattern vs. diploidy). RESULTS: DICM revealed diploidy in 83% of 239 endoscopies, an intermediate pattern in 8.8%, and aneuploidy in 8.4%. An intermediate DICM result carried a relative risk (RR) of 12 and aneuploidy a RR of 27 for high-grade dysplasia/adenocarcinoma. Adding DICM to the standard biopsy protocol, a pathological cytometry result (aneuploid or intermediate) was found in 25 of 239 endoscopies (11%; 18 patients) with low-risk histology (no high-grade dysplasia or adenocarcinoma). During follow-up of 14 of these 18 patients, histological deterioration was seen in 3 (21%). CONCLUSION: DICM from brush cytology may add important information to a standard biopsy protocol by identifying a subgroup of BE-patients with high-risk cellular abnormalities.

Antibiotic cement nail for the treatment of posttraumatic intramedullary infections of the tibia: Midterm results in 10 cases.

INTRODUCTION: This is a single, level 1 trauma centre, prospective consecutive patient series with intramedullary infection in the presence of unstable tibial fracture treated using the Kirschner wire-reinforced, antibiotic cement nail. PATIENTS AND METHODS: A total of 10 consecutive patients (eight males and two females) with a mean age of 42 years (range, 20-59) suffering from infection after intramedullary nailing for tibial fracture, admitted during a period of 4 years, were included. An antibiotic cement-coated nail, handmade at the time of surgery, was implanted in all patients. This was followed by a standardised 6-week treatment protocol, extraction of the nail and definitive fixation. RESULTS: At 6 years of follow-up, infection eradication and bony union were possible in all of the patients. No further infection treatment was necessary; however, all of our patients underwent additional procedures (mean: four additional procedures per patient) for cosmetic or other non-infectious reasons (bone grafting, muscle flaps, etc.). CONCLUSIONS: The antibiotic cement-coated nail seems to be an effective treatment for intramedullary infections of the fractured tibia.

Les groupes de parole de prévention de la récidive au sein des SPIP: une évolution centrée sur la gestion du risque, entre théorie et adaptation pratique

En France, les différentes réorientations pénales et les missions confiées au Service Pénitentiaire d'Insertion et de Probation (SPIP) placent l'évaluation des risques de récidive et leur prévention au centre de la pratique professionnelle des Conseillers Pénitentiaires d'Insertion et de Probation (CPIP). Les récentes évolutions législatives des missions des SPIP, les mutations identitaires et des pratiques qu'elles impliquent -en particulier les Groupes de Paroles de Prévention de la Récidive (GPPR)-, caractérisent une évolution centrée sur la gestion du risque. Partant de critiques dans la littérature sur la notion de gestion du risque de récidive dans les pratiques pénales et de ce qu'elle induit dans les modes d'appréhension des sujets et dans les interventions professionnelles, l'article met en relation les réorientations vers une gestion du risque telles qu'elles peuvent apparaître dans les textes, missions et référentiel du SPIP, avec une évaluation des pratiques professionnelles centrées sur les GPPR intégrés au sein des SPIP. Y a-t-il infiltration et remodelage des pratiques ? Si c'est bien le cas, on examine où se situe le niveau pertinent de cette influence et du réaménagement des pratiques.

Problème de l'exposition lors d'examens ionisants chez les enfants souffrant de malformations cardiaques au Centre Hospitalier Universitaire Vaudois (CHUV)

Le nombre d'examens fluoroscopiques pratiqués en fluoroscopie est en augmentation constante en cardiologie pédiatrique. Ces examens ont un bénéfice évident pour le diagnostic et la thérapie de pathologies cardiaques complexes mais ils sont également la cause d'exposition à des hautes doses de radiation. Notre étude propose donc d'analyser cette pratique au Centre Hospitalier Universitaire Vaudois (CHUV) ainsi que d'établir des niveaux de référence diagnostiques et de rechercher les moyens possibles de diminution de doses. La base de données que nous avons analysé provient du service de cardiologie pédiatrique du CHUV (Lausanne). Elle contient 873 examens fluoroscopiques pratiqués entre le 1er janvier 2003 et le 31 décembre 2011 et se compose des données démographiques, du temps de scopie en minutes et du dose area product (DAP) en Gycm 2 pour chaque examen. Les examens sont séparés en deux modalités, diagnostique et interventionnel et ont été pratiqués sur l'installation GE jusqu'en juillet 2010 et par la suite sur l'installation Philips. L'analyse s'est faite sur Excel et sur JMP Statistics afin d'établir la distribution démographique de l'échantillon, les moyennes et percentiles 75. Les examens diagnostiques ont été étudié par classes d'âge et les examens interventionnels selon une classification d'intervention (Ranking) établie en collaboration avec le médecin responsable de ces procédures au CHUV. Seuls les groupes d'examens ayant un nombre égal ou supérieur à 20 ont été analysés. Nous avons donc analysé 873 examens, dont 512 diagnostiques et 361 interventionnels. Le temps de scopie moyen pour l'ensemble des examens diagnostiques est de 11.91 minutes et le DAP moyen de 12.04 Gycm2. Concernant les examens interventionnels, les moyennes de temps de scopie et de DAP sont de 17.74 minutes et 9.77 Gycm2 respectivement. En plus des analyses par classes d'âges et par ranking, nous avons étudié les examens selon leurs données démographiques ainsi que par pathologie et par installation. L'ensemble des examens diagnostiques connaissent une diminution significative (p<0.0001) de 30% pour le temps de scopie moyen et de 60% pour le DAP moyen en passant de l'installation la plus ancienne, GE, à la plus récente, Philips. Concernant les examens interventionnels, La différence entre les deux installations est encore plus marquée avec un temps de scopie moyen 55 % inférieur ( Gycm2) et un DAP moyen 73 % (p=0.0002) plus faible sur Philips par rapport à GE. Ces différences sont principalement expliquées par l'apport de nouveaux outils sur l'installation Philips, tels que la digitalisation et le traitement de l'image, de la possibilité de changer le nombre d'images par seconde durant un examen ainsi que de l'amélioration de la pratique des examinateurs. Nous avons pu définir des percentiles 75 pour les examens diagnostiques par classes d'âge et par pathologie et pour les examens interventionnels selon le ranking établi par le Dr Di Bernardo.

Impact of a telenursing service on satisfaction and health outcomes of children with inflammatory rheumatic diseases and their families: a crossover randomized trial study protocol.

BACKGROUND: Pediatric rheumatic diseases have a significant impact on children's quality of life and family functioning. Disease control and management of the symptoms are important to minimize disability and pain. Specialist clinical nurses play a key role in supporting medical teams, recognizing poor disease control and the need for treatment changes, providing a resource to patients on treatment options and access to additional support and advice, and identifying best practices to achieve optimal outcomes for patients and their families. This highlights the importance of investigating follow-up telenursing (TN) consultations with experienced, specialist clinical nurses in rheumatology to provide this support to children and their families. METHODS/DESIGN: This randomized crossover, experimental longitudinal study will compare the effects of standard care against a novel telenursing consultation on children's and family outcomes. It will examine children below 16 years old, recently diagnosed with inflammatory rheumatic diseases, who attend the pediatric rheumatology outpatient clinic of a tertiary referral hospital in western Switzerland, and one of their parents. The telenursing consultation, at least once a month, by a qualified, experienced, specialist nurse in pediatric rheumatology will consist of providing affective support, health information, and aid to decision-making. Cox's Interaction Model of Client Health Behavior serves as the theoretical framework for this study. The primary outcome measure is satisfaction and this will be assessed using mixed methods (quantitative and qualitative data). Secondary outcome measures include disease activity, quality of life, adherence to treatment, use of the telenursing service, and cost. We plan to enroll 56 children. DISCUSSION: The telenursing consultation is designed to support parents and children/adolescents during the course of the disease with regular follow-up. This project is novel because it is based on a theoretical standardized intervention, yet it allows for individualized care. We expect this trial to confirm the importance of support by a clinical specialist nurse in improving outcomes for children and adolescents with inflammatory rheumatisms. TRIAL REGISTRATION: ClinicalTrial.gov identifier: NCT01511341 (December 1st, 2012).

Greenstick fractures of the middle third of the forearm. A prospective multi-centre study.

BACKGROUND: Greenstick fractures suffered during growth have a high risk for refracture and posttraumatic deformity, particularly at the forearm diaphysis. The use of a preemptive completion of the fracture by manipulation of the concave cortex is controversial and data supporting this approach are few. AIM: Aim of this study was to determine the factors which predispose to refracture and deformities, and to define therapeutic strategies. METHODS: We prospectively gathered clinical and radiographic data over a period of one year on greenstick fractures of the middle third of the forearm in children as part of a multi-centre study. Endpoint was a follow-up visit at one year. Radiographic deformity, state of consolidation at resumption of physical activities and refracture rate were analysed statistically (ANOVA, Student's t-test and Pearson's chi-square test) with regard to patient age, gender, fracture type, therapy and time in plaster. RESULTS: We collected the data of 103 patients (63 boys, 40 girls), average age 6.6 years (1.3-14.5 years), the vast majority of whom had a combined greenstick fracture of the radius and ulna. 6.7% of the patients sustained a refracture within 49 days (29-76) after plaster removal. They were significantly older (p=0.017) with a significantly higher incidence of manual completion of the fracture with radiographic signs of partial consolidation (p=0.025). Residual deformities were significantly smaller after completion of the fracture compared to reduction without completion (p=0.019) or plaster fixation alone (p<0.005). CONCLUSIONS: Completion of a greenstick fracture does not prevent refracture. Nevertheless, it diminishes the extent of secondary deformities in cases where the primary angulation exceeds the remodelling capacity. Prevention of refracture should include a routine radiographic follow-up 4-6 weeks after injury with continuation of plaster fixation in cases of partial consolidation.

Effective continuing professional development for translating shared decision making in primary care: A study protocol.

Background: Shared decision making (SDM) is a process by which a healthcare choice is made jointly by the healthcare professional and the patient. SDM is the essential element of patient-centered care, a core concept of primary care. However, SDM is seldom translated into primary practice. Continuing professional development (CPD) is the principal means by which healthcare professionals continue to gain, improve, and broaden the knowledge and skills required for patient-centered care. Our international collaboration seeks to improve the knowledge base of CPD that targets translating SDM into the clinical practice of primary care in diverse healthcare systems. Methods: Funded by the Canadian Institutes of Health Research (CIHR), our project is to form an international, interdisciplinary research team composed of health services researchers, physicians, nurses, psychologists, dietitians, CPD decision makers and others who will study how CPD causes SDM to be practiced in primary care. We will perform an environmental scan to create an inventory of CPD programs and related activities for translating SDM into clinical practice. These programs will be critically assessed and compared according to their strengths and limitations. We will use the empirical data that results from the environmental scan and the critical appraisal to identify knowledge gaps and generate a research agenda during a two-day workshop to be held in Quebec City. We will ask CPD stakeholders to validate these knowledge gaps and the research agenda. Discussion: This project will analyse existing CPD programs and related activities for translating SDM into the practice of primary care. Because this international collaboration will develop and identify various factors influencing SDM, the project could shed new light on how SDM is implemented in primary care.

Neurorééducation précoce au Centre hospitalier universitaire vaudois: du rêve à la réalité [Early neurorehabilitation in an acute university hospital: from dream to reality].

The need for an early neurorehabilitation pathway was identified in an acute university hospital. A team was formed to draw up and implement it. A neuro-sensorial, interdisciplinary and coordinated therapy program was developed, focused on tracheostomised patients as soon as they were admitted to the intermediate care in neurology and neurosurgery. The impact of this care plan was evaluated by comparing the results obtained with that pertaining to patients treated previously in the same services. The comparison showed a reduction of 48% of the mean duration of tracheostomy, of 39% in the time to inscription in a neurorehabilitation centre and of 20% in the length of stay in the intermediate care. An early neurorehabilitation care program, with an interdisciplinary and coordinated team, reduces complications and lengths of stay.
