La drépanocytose, maladie génétique, peut désormais être traitée et guérie par une allogreffe intrafamiliale de cellules souches hématopoïétiques (CSH). Cette greffe a fait ses preuves sur le plan médical et est de plus en plus utilisée, notamment chez les jeunes enfants. Elle leur donne le statut de chimère biologique grâce à la moelle osseuse d’un frère ou d’une sœur. Comment vivent-ils alors cette expérience médicale lourde et ses conséquences sur le plan psychologique ? Cette étude prospective a permis de décrire le vécu de la greffe chez trois enfants drépanocytaires âgés de 5 à 7 ans sur une durée d’un an par une méthodologie qualitative à partir des dessins et du discours des enfants. Ces enfants sont confrontés à des modifications de la perception d’eux-mêmes et de la représentation du temps entre rupture et continuité. Face à cette épreuve, on observe une oscillation entre un besoin de maîtrise et au contraire de passivité. La greffe va mettre à mal les enveloppes psychiques et leurs qualités. De plus, une problématique du don et de la dette va émerger. En effet, la greffe entraine un bouleversement dans la construction de leur personnalité, avec une réminiscence de processus archaïques. La représentation du changement pour ces enfants et le sentiment de guérison qui en découle sont complexes, et impliquent un véritable travail de deuil de la maladie qui s’avère long et douloureux. Il s’agit d’une période de vulnérabilité pour l’enfant qui nécessite un accompagnement psychologique.
La légitimité démocratique de la gouvernance économique européenne : la mutation de la fonction parlementaire
Authors: Allemand Frédéric , Martucci Francesco 
Published: January 2015

Le Traité de Lisbonne se présente comme « le traité des parlements ». Cependant, pour répondre à la crise financière et à la crise des dettes souveraines, les réformes de l’Union économique et monétaire accentuent le phénomène de relégation du Parlement européen et des parlements nationaux dans le processus décisionnel. En contrepartie, les parlements obtiennent des pouvoirs renforcés en matière de reddition des comptes. Le renforcement du principe démocratique dans l’UEM exige une implication accrue des parlements. Cela suppose notamment d’éviter le recours aux accords intergouvernementaux, d’organiser un comité zone euro au sein du Parlement européen et de tenir une Convention socio-économique tous les ans pour définir les grandes orientations des politiques de l’UEM.
Quelle gouvernance de la zone euro ?
Authors: Mathieu Catherine , Sterdyniak Henri 
Published: January 2015

La période d’avant-crise, comme la crise, ont mis en évidence les défauts d’organisation de la zone euro. Il est difficile d’avoir une monnaie unique entre des pays dont les conjonctures et les problèmes structurels diffèrent. La gouvernance mise en place (pas de garantie des dettes publiques, des règles arbitraires centrées sur les seules finances publiques) n’était pas satisfaisante. Les institutions européennes ont voulu imposer une stratégie (paralysie des politiques nationales, baisse des dépenses publiques, réformes structurelles libérales) qui a échoué. Avant la crise, les divergences se sont creusées entre les pays du Nord et ceux du Sud ; la crise les a rendues insoutenables. Depuis, le Pacte budgétaire a renforcé des règles sans fondement économique. Les politiques d’austérité aveugles se sont révélées catastrophiques pour la croissance et la cohésion de la zone. Les procédures mises en place renforcent la surveillance des politiques économiques des pays membres, sans organiser une véritable coordination des politiques nationales. Elles instaurent une solidarité limitée et chèrement payée. Les projets proposés de fédéralisme budgétaire ne peuvent compenser la perte d’autonomie des politiques nationales. Les dettes publiques des pays membres doivent redevenir des actifs sans risque, ceci grâce à la garantie de BCE. Ceci nécessite d’instaurer une véritable coordination des politiques économiques nationales ; celle-ci doit se donner explicitement comme objectif la croissance, le plein-emploi, la résorption ordonnée des déséquilibres entre pays membres. L’Europe doit réaffirmer sa spécificité : son modèle social, sa volonté de préparer la transition écologique. Ce n’est que dans le cadre de ce projet commun qu’elle pourra progresser.
Le(s) marché(s) du travail européen(s)
Authors: Cornilleau Gérard 
Published: January 2015

Depuis sa fondation, l’Union européenne a connu une accentuation de la dispersion de ses systèmes sociaux. L’objectif d’une Union sociale, complétant l’Union économique et monétaire s’éloigne de plus en plus. L’absence d’un marché du travail régulé en commun par les pays de l’Union est un facteur de déstabilisation qui pousse à la concurrence sociale et à la déflation salariale. Pour éviter les risques liés à une telle situation il faudrait trouver un accord sur les politiques à mettre en œuvre pour revenir au plein emploi et choisir entre partage du travail « libéral » ou « social ». L’absence de perspectives à court terme pour une unification sociale complète implique l’acceptation de frontières sociales gérées en commun qui permettent à la fois la mobilité et la protection effective des travailleurs.
La politique commerciale européenne
Authors: Boulanger Pierre H. , Messerlin Patrick 
Published: January 2015

Cet article replace la politique commerciale européenne dans le cadre beaucoup plus vaste de l’intégration des marchés régionaux et internationaux. Si l’OMC est indiscutablement le meilleur forum pour négocier des objectifs quantifiables et assurer un règlement des différends, sa primauté en matière réglementaire est moins évidente. L’UE est engagée dans la négociation de nombreux accords préférentiels de commerce et d’investissement, dont l’objectif diffère selon le pays ou la région partenaire. Ainsi cet article propose de distinguer une politique du « cercle proche » (pays voisins de l’UE) dominée par un objectif de stabilité politique et celle du « cercle large » (pays de niveau de développement comparable à celui de l’UE) dominée par un objectif de croissance économique.

Introduction Knee osteoarthritis (OA) is the most common articular disease. Different methods are used to alleviate the symptoms of patients with knee OA, including analgesics, physical therapy, exercise prescription, and intra-articular injections (glucocorticoids, hyaluronic acid [HA], etc). New studies have focused on modern therapeutic methods that stimulate cartilage healing process and improve the damage, including the use of platelet-rich plasma (PRP) as a complex of growth factors. Due to the high incidence of OA and its consequences, we decided to study the long-term effect of intraarticular injection of PRP and HA on clinical outcome and quality of life of patients with knee OA. Method This non-placebo-controlled randomized clinical trial involved 160 patients affected by knee OA, grade 1–4 of Kellgren–Lawrence scale. In the PRP group ( n = 87), two intra-articular injections at 4-week interval were applied, and in the HA group ( n = 73), three doses of intra-articular injection at 1-week interval were applied. All patients were prospectively evaluated before and at 12 months after the treatment by Western Ontario and McMaster Universities Arthritis Index (WOMAC) and SF-36 questionnaires. The results were analyzed using SPSS 16.1 software (RCT code: IRCT2014012113442N5). Results At the 12-month follow-up, WOMAC pain score and bodily pain significantly improved in both groups; however, better results were determined in the PRP group compared to the HA group ( P < 0.001). Other WOMAC and SF-36 parameters improved only in the PRP group. More improvement (but not statistically significant) was achieved in patients with grade 2 OA in both the groups. Conclusion This study suggests that PRP injection is more efficacious than HA injection in reducing symptoms and improving quality of life and is a therapeutic option in select patients with knee OA who have not responded to conventional treatment.
Leveraging Electronic Tablets for General Pediatric Care
Authors: McKee S. , Dugan T.M. , Downs S.M. , Anand V. 
Published: January 2015

SummaryBackground: We have previously shown that a scan-able paper based interface linked to a computerized clinical decision support system (CDSS) can effectively screen patients in pediatric waiting rooms and support the physician using evidence based care guidelines at the time of clinical encounter. However, the use of scan-able paper based interface has many inherent limitations including lacking real time communication with the CDSS and being prone to human and system errors. An electronic tablet based user interface can not only overcome these limitations, but may also support advanced functionality for clinical and research use. However, use of such devices for pediatric care is not well studied in clinical settings.Objective: In this pilot study, we enhance our pediatric CDSS with an electronic tablet based user interface and evaluate it for usability as well as for changes in patient questionnaire completion rates.Methods: Child Health Improvement through Computers Leveraging Electronic Tablets or CHICLET is an electronic tablet based user interface. It is developed to augment the existing scan-able paper interface to our CDSS. For the purposes of this study, we deployed CHICLET in one outpatient pediatric clinic. Usability factors for CHICLET were evaluated via caregiver and staff surveys.Results: When compared to the scan-able paper based interface, we observed an 18% increase or 30% relative increase in question completion rates using CHICLET. This difference was statistically significant. Caregivers and staff survey results were positive for using CHICLET in clinical environment.Conclusions: Electronic tablets are a viable interface for capturing patient self-report in pediatric waiting rooms. We further hypothesize that the use of electronic tablet based interfaces will drive advances in computerized clinical decision support and create opportunities for patient engagement.Citation: Anand V, McKee S, Dugan TM, Downs SM.

Ex vivo Accuracy of Root Zx Ii, Root Zx Mini and RomiApex A-15 Apex Locators in Extracted Vital Pulp Teeth
Authors: da Silva Thaís M , Alves Flávio RF 
Published: January 2015

ABSTRACT
The objective of this study was to compare, ex vivo, the accuracy of three electronic apex locators (EALs), Root ZX II, Root ZX Mini and RomiApex A-15, in detecting the apical foramen (AF). Forty extracted single-rooted human teeth with vital pulp were used in this study. After access preparation, the root canal length of each tooth was measured by placing a #10 file until the tip was visible at the AF under a stereomicroscope. The teeth were subsequently embedded in an alginate model. In each root canal, all three EALs were used to determine the working length, which was defined as the zero reading or equivalent. The distance between the file tip and AF was measured to an accuracy of 0.01 mm. Results were analyzed using analysis of variance and the Chi-squared test. Root ZX II, Root ZX Mini and RomiApex A-15 were accurate within 0.5 mm, 62.5, 56.2, 50% of the time. No significant differences were found between the three EALs (p > 0.05). Considering all EALs, the mean distance from the file tip to AF was 4.49 mm. The accuracy of the three EALs evaluated in this study was not statistically significantly different. The ‘Apex’ or ‘0.0’ marks of the EALs do not indicate the AF itself, but just a position coronal 0.49 mm to the AF. Using a tolerance of ± 0.5 mm from the actual lengths, the ZX II yielded the most acceptable measurements.

Published: January 2015

ABSTRACT
Preclinical exercises are very important for the dental students in order to master various dental techniques. The objective of this article is to introduce a new preclinical working model named Restoflex. It is especially designed for the students to carry out various restorative and endodontic procedures in an environment that closely simulate clinical situations. This will help them to provide a smooth transition from preclinical environment to the clinical one. It would also mean an increased confidence level and the efficiency with which the students would deal with their cases.

Effect of Double Coating of One-step Self-etching Adhesive on Micromorphology and Microtensile Bond Strength to Sound vs Demineralized Dentin
Authors: Oliveira Cerida Aurelia Rodrigues , França Fabiana Mantovani Gomes , Basting Roberta Tarkany , Turssi Cecília Pedroso , Amaral Flavia Lucisano Botelho do 
Published: January 2015

ABSTRACT

Aim
The purpose of the present study was to evaluate (1) the one-step adhesive system application method (doubling the adhesive coatings) in regard to microtensile bond strength (MTB) and (2) the interfacial morphology of one-step adhesives to sound vs demineralized dentin.

Materials and methods
Forty dentin fragments were randomly allocated to 2 groups: D. demineralized dentin and S. sound dentin. Specimens were also subdivided into 2 groups (n = 10), according to the one-step adhesive [AEO (Adper Easy One), 3M ESPE] application method: M, According to the manufacturer's instructions, and D, based on the application of two consecutive layers. After adhesive light polymerization, a resin composite block (Filtek Z250, 3M ESPE) was built on the dentin surface. Resin-tooth blocks were sectioned into 0.9 mm thick slabs, and one slab of each block was prepared for adhesive interface analysis by scanning electron microscopy (SEM). The remaining slabs were sectioned into 0.8 mm2 sticks that were subjected to tensile stress (0.5 mm/min). Data were subjected to two-way ANOVA and Tukey's test (α = 0.05).

Results
The application of two consecutive layers of AEO adhesive system did not influence MTB values for sound dentin. When two consecutive layers of one-step adhesive system were applied, MTB was statistically greater in demineralized vs sound dentin. SEM analysis demonstrated that the application of two consecutive adhesive layers to sound and demineralized dentin produced longer resin tags.

Conclusion
It can be concluded that the application of two consecutive adhesive layers improved bond strength to demineralized dentin, but no such effect was observed for sound dentin.

Clinical significance
Application of double coats of one-step self-etching adhesive improved bond strength to demineralized dentin.

Evaluation of Mental Foramen Position from Panoramic Dental Radiographs
Authors: Ajmal Muhammed 
Published: January 2015

ABSTRACT

Objective
Evaluate the position of mental foramen by measuring the vertical bone height from digital panoramic radiograph and also the variation of resorption pattern by gender and extraction time frame.

Materials and methods/study design
Digital panoramic radiographs of 500 patients were reviewed. The study population was divided into four age groups aged 30 to 70 years as (30-39, 40-49, 50-59 and 60-70 years of age).
Radiographic Position of mental foramen was evaluated in each panoramic radiograph by measuring the distance from the marginal bone to the mental foramen was being measured.
Measurements were taken in each radiograph using Cliniview software. The data collected was subjected to statistical analysis using paired students t-test and chi-square tests.

Results and conclusion
In our study it was noted that the vertical measurements calculated from the superior margin of mental foramen to the crest of alveolar ridge were greater in edentulous men than in women. This measurement decreased significantly with age. We have noted here that resorption pattern between males and females can be used as an early diagnostic tool and for implant analysis. Studies comparing right and left side edentulous mandibular region are needed for further confirmation.

Clinical and Radiographic Evaluation of Narrow-Diameter Titanium-Zirconium Implants in Unilateral Atrophic Mandibular Distal Extensions: A 1-Year Pilot Study
Authors: El-Sheikh Ali M , Shihabuddin Omar F 
Published: January 2015

ABSTRACT

Background
The use of endosseous dental implants has led to more sophisticated fixed options when considering treatment of patients with distal extensions. The use of narrow-diameter implants may reduce the necessity for bone augmentation. The mechanical strength of titanium is limited, so titanium alloys with greater tensile and fatigue strength may be preferable.

Purpose
The purpose of this study was to evaluate clinically and radiographically the performance of narrow-diameter bone level implants made from titanium-zirconium alloy (TiZr, RoxolidTM) in restoring unilateral atrophic mandibular distal extensions with fixed dental prostheses.

Materials and methods
Twenty partially edentulous patients with unilateral atrophic mandibular distal extensions received two 3.3 mm diameter bone level TiZr implants (Straumann AG, Basel, Switzerland). The two implants were restored with 3-units ceramo-metal fixed partial dentures. Standardized clinical and radiographic parameters (survival rate, probing pocket depth and marginal bone loss) were evaluated at the time of the completion of the prosthetic treatment (baseline) and after 3, 6 and 12 months of functional loading. Prosthetic complications were also assessed.

Results
The survival rate for narrow-diameter bone level TiZr implants was 100% after 1 year of functional loading. There were no statistically significant differences between the values of probing pocket depth over the follow-up period. All implants showed less than 1 mm of marginal bone loss at the end of the follow-up period.

Conclusion
Within the limitations of this 1-year pilot study, the use of narrow-diameter bone level TiZr implants appears to be predictable in restoring the unilateral atrophic mandibular distal extensions. This type of implants meets established success and survival criteria after 1 year.

Apical Extrusion of Debris and Irrigant using Novel Preparation Systems
Authors: Uzunoglu Emel , Görduysus Melahat 
Published: January 2015

ABSTRACT

Aim
The aim of this in vitro study was to assess the amount of apically extruded debris and irrigant using Reciproc vs self-adjusting file (SAF) and to investigate the effect, if any, of gravitational force via mandibular and maxillary positioning of the teeth.

Materials and methods
Forty human mandibular premolars were randomly assigned to four groups of 10 teeth each. The root canals were instrumented according to the manufacturers’ instructions using the Reciproc and SAF. Sodium hypochlorite was used as the irrigant. The apically extruded debris was collected in pre-weighted glass vials using the Myers and Montgomery method, and teeth were placed in vials both in downward and upward positions. After drying, the mean weight of debris was assessed with a microbalance and statistically analyzed using two-way ANOVA with Bonferroni correction.

Results
All instrumentation techniques and positions caused measurable apical extrusion of debris. A significant difference was observed according to position and instrument used (p < 0.05). The Reciproc extruded significantly more debris than SAF and vial downward position extruded significantly more debris than upward position (p < 0.05).

Conclusion
Under the conditions of this study, all systems caused apical debris extrusion, especially in the downward position.

Clinical significance
According to results of this study, the SAF was associated with less debris extrusion compared to the Reciproc in both mandibular and maxillary positions.

ABSTRACT
This in vitro study evaluated the influence of prestretching, in the force decay of orthodontic elastic chains, at three time intervals 2, 7 and 30 days with the brands Morelli, Orthometric and American Orthodontics. In the experimental group, prestretching was performed, stretching the elastics to increase them by 50% of their original length three times in a quick and sequential mode. All of the elastic chains were kept stretched and stored in artificial saliva at 37°C until the time of force measurement. For comparisons between the control and experimental groups, the Mann-Whitney test was used. For comparisons between time points and brands, the Kruskal-Wallis test was used, and for multiple comparisons, Miller's post-hoc test was used. The results showed statistically significant differences among the different commercial brands tested at the initial time point. The mean force at the initial time point ranged from 2.57 to 3.17 N. By day 2, the force values were between 0.97 and 1.49 N; by day 7, the values were 0.56 and 0.94 N. By day 30, the force values ranged between 0.27 and 0.66 N. We concluded that performing and duration of prestretching and the brand all influenced the force decay of orthodontic elastic chains. Time had a greater influence on the decay of the elastics than brand or prestretching.
