The paper deals with analysis of structural lightweight concrete. New lightweight concrete mixture made with expanded clay aggregate has been proposed and applied for experimental rein-forced concrete beams. Totally 8 beams with different rein-forcement ratios (0.309%, 0.557%, 0.895% and 1.255%) were tested under short-term four point bending loading. Stress-strain behavior of the beams under considerations has been investigated. Average strains at 4 different levels of pure bend-ing zone and vertical displacements at 12 different points of the beam were measured. During the test, deformations and crack-ing of the pure bending zone were additionally observed using high-speed digital video cameras. The data obtained by cameras were analyzed using digital image correlation technique. Applying the test data bending moments and curvature diagrams were derived for each beam. The obtained relationships were compared with theoretical results calculated using design code methods LST EN and STR. Using the inverse algorithm developed by VGTU, tension reinforced lightweight concrete stress and strain diagrams were obtained, which were adapted to numerical modeling by software ATENA. Moment and curvature diagrams obtained by finite elements program were compared with experimental moment and curvature diagrams. Good agreement between both diagrams has been obtained.

DIRECT SHEAR TESTS WITH EVALUATION OF VARIABLE SHEARING AREA / TIESIOGINIO KIRPIMO BANDYMAI ĮVERTINANT KINTAMĄ KERPAMĄJĮ PLOTĄ
Authors: Skuodis Šarūnas , Tamošiūnas Tadas
Published: January 2015

Investigations of soil shear strength properties for Baltic Sea shore sand along Klaipėda city are presented. Investigated sand angle of internal friction (φ) and cohesion (c) is determined via two different direct shear tests procedures. First procedure is standard and ordinary in geotechnical practice, when direct shear test is provided using constant shearing area A0. Second test procedure is different because shearing area according to horizontal displacement each test second is recalculated. This recalculated shearing area author’s call corrected shearing area A. Obtained normal and tangential stresses’ difference via two different testing procedures was 10%.
Šiame straipsnyje yra pristatyta idėja, kaip įvertinti grunto kerpamojo stiprumo parametrus, t. y. vidinės trinties kampą (φ) ir sankibą (c). Eksperimentiniams bandymams atlikti buvo naudotas Baltijos jūros pakrantės smėlinis gruntas ties Klaipėda. Grunto tiesioginio kirpimo bandymai atlikti dviem skirtingomis kirpimo metodikomis. Pirmoji metodika yra standartizuota ir įprasta atliekant geotechninius tyrimus, kai kerpamasis plotas yra vertinamas kaip pastovus plotas A. Antroji kirpimo metodika skiriasi nuo pirmosios grunto kirpimo ploto įvertinimu. Antrojoje metodikoje grunto kerpamasis plotas yra perskaičiuojamas tiesiogiai pagal horizontalųjį poslinkį. Horizontaliojo poslinkio indikatoriaus rodmenys yra registruojami kiekvieną sekundę, todėl kas sekundę yra perskaičiuojamas vis naujas grunto kerpamasis plotas. Atliekant bandymus skirtingomis metodikomis, nustatytas vertikalaus normalinio ir tangentinio įtempių skirtumas, kuris apytiksliai lygus 10 %.

Annoncer une maladie génétique à l'enfant. Désir de savoir, besoin de comprendre
Authors: Gargiulo Marcela , Herson Ariane , Angeard Nathalie
Published: January 2015

L’annonce du diagnostic à l’enfant reste un problème complexe sur lequel il n’existe pas de consensus. Lorsqu’il n’y pas de traitement curatif ou préventif, il est difficile pour les parents et pour les médecins de parler avec l’enfant de sa maladie et de son origine génétique. Un des enjeux fondamentaux de l’annonce à l’enfant est de l’accompagner dans sa quête de savoir et dans une mise en sens de ce qui lui arrive. Les questions que l’enfant peut se poser sur sa maladie logent au plus profond de la pulsion épistémologique qui détermine pour beaucoup l’attitude que l’enfant aura face au savoir et aux apprentissages futurs. Son envie de savoir et de comprendre ne devrait pas être étouffée par une volonté de lui épargner quelques supposées souffrances, qu’une parole pourrait, au contraire, libérer. Dans l’annonce à l’enfant, il ne s’agit pas d’informer l’enfant à tout prix, mais de pouvoir établir un dialogue avec lui, rythmé par ses interrogations.
La drépanocytose de l'adolescence à l'âge adulte
Authors: Guitton Corinne
Published: January 2015

Accepter une maladie chronique, génétique de surcroît comme la drépanocytose, implique l’acceptation d’une atteinte à l’intégrité du corps, d’une privation de liberté, de dépendance supplémentaire, et d’une possible amputation de l’avenir. Cette démarche est quasi antinomique lors de l’adolescence où l’on se veut invulnérable. La gestion du quotidien et la préparation au passage vers le monde adulte deviennent des enjeux majeurs. En effet, c’est au sein de la population des jeunes adultes drépanocytaires que l’on observe un pic de fréquence des hospitalisations et des décès, et ce dans les mois qui suivent le transfert de leur prise en charge en secteur adulte. La transition doit être anticipée et abordée dès le début de l’adolescence. Les équipes pédiatriques et adultes doivent élaborer ensemble les modalités de ce passage en tenant compte des ressources locales et s’appuyer, quand cela est possible, sur l’éducation thérapeutique des patients et de leurs familles.
Les réunions de synthèses éducatives : espaces de socialisation, aspects de soi diffractés et processus cohésifs
Authors: Gaultier Sydney
Published: January 2015

En institution éducative, les prises en charge des jeunes usagers sont ponctuées par des temps de synthèse désignant de façon formelle la rencontre autour de l’enfant entre l’institution, le service placeur et la famille. Ces temps souvent extrêmement intenses ont plusieurs objectifs cohérents avec les impératifs légaux de projet personnalisé et de participation des parents. Toutefois, c’est un aspect implicite et pour autant essentiel pour le sujet qui nous intéresse. La synthèse n’est pas seulement un temps de collecte et de confrontation des différents aspects du sujet, elle est aussi l’occasion d’opérer pour lui-même un classement de ses différentes dispositions et, ainsi, de répondre à une synthèse collective par un processus de cohésion interne. Lorsqu’elle est menée à bien et que la situation le permet, la synthèse est alors un opérateur interne de changement pour le sujet.
Le risque de confusion en droit des marques : entre extension et évolution
Authors: Basire Yann
Published: January 2015

Contrairement aux autres droits de propriété intellectuelle, le droit des marques a fait l’objet d’une harmonisation particulièrement poussée qui permet de mettre en lumière le rôle majeur de la CJUE dans la consistance des notions clés du droit des marques. Il en va tout particulièrement du risque de confusion. Définir le risque de confusion ne soulève pas de difficultés particulières. Plus délicates sont les questions de son domaine et son appréciation. Le texte de la directive semble restreindre la démonstration d’un risque de confusion aux hypothèses où une similitude existe entre les signes en conflit et/ou les produits et services désignés. Cependant, la Cour de justice a « brouillé les pistes » avec sa jurisprudence relative aux fonctions de la marque. S’agissant de l’appréciation du risque de confusion, la tâche de la Cour de justice était plus ardue, les dispositions communautaires étant plus laconiques. Il appartenait donc à la Cour de dégager une méthode d’appréciation du risque de confusion, garantissant un juste équilibre entre les intérêts des titulaires, des concurrents et des consommateurs, susceptible de s’imposer sans disparité d’application à tous les États membres. Malheureusement, une démarche pragmatique n’est pas toujours synonyme de cohérence. ?
Les passions au miroir des arts dans Le Rouge et le Noir
Authors: Glaudes Pierre
Published: January 2015

Dans Le Rouge et le Noir , les œuvres qui permettent aux personnages de se représenter leurs émotions ramènent parfois la singularité du sentir à un cliché. D’autres fois, elles sont une éducation du sentiment : elles prennent la valeur d’une découverte de soi à l’épreuve de modèles héroïques ou romanesques. D’autres fois encore, elles ont un pouvoir de révélation : investis par le désir, leurs scénarios paradigmatiques font sourdre à la conscience des aspirations jusque-là confuses. Le meilleur emploi qu’on puisse en faire procède d’une connaturalité de l’érotique et de l’esthétique, les passions trouvant spontanément dans les arts un langage qui en saisit nuances et potentialités.
La face cachée de la honte
Authors: Komorowska Agnieszka
Published: January 2015

L’article examine la mise en scène théâtrale de la honte dans les travaux de Sartre, Lacan et Bourdieu. Nous partons de l’hypothèse que la représentation de la honte est confrontée à un paradoxe : D’une part, cette émotion semble se refuser à une mise en scène. D’autre part, elle provoque un jeu de masques et une multitude des représentations fortement théâtrales. Pour comprendre comment ce paradoxe introduit un aspect esthétique dans l’expérience de l’émotion, nous abordons une triple théâtralité concernant l’aspect de la mascarade, le regard esthétique, et le clivage du sujet honteux.
Jeux vidéo horrifiques et artialisation des émotions extrêmes
Authors: Baychelier Guillaume
Published: January 2015

On examinera en quoi les jeux vidéo horrifiques rendent possible l’expérience d’émotions extrêmes comme de plaisirs mêlés de déplaisir dont la teneur ressortit au sublime dans la perspective de Schiller. Nous analyserons la possibilité du dépassement des cas limites du dégoût et de l’image volumique tels qu’analysés par Kant. Enfin, nous chercherons à approfondir l’approche de l’artialisation de Roger en examinant le rôle du cadrage dans la pratique vidéoludique, en prenant la mesure du passage d’une artialisation in visu à une artialisation vécue in acto .
Black African Nurses Educated in the United States
Authors: Smith Amy , Smyer Tish
Published: January 2015

Black Africans are one of the fastest growing immigrant and refugee populations in the United States, having increased by 100% in the 2000s. The purpose of this study was to gain an understanding of how Black African nurses experience nursing education within the United States. This qualitative study provided a rich description of the phenomenon. Nine Black African nurses from the midwestern United States participated. Five male and four female participants represented the countries of Sierra-Leone, Kenya, Liberia, Eritrea, and Ethiopia. Seven participants had been in the country less than 2 years, and two had been in the country less than 4 years. Optimistic determination was the essence of how participants adapted to challenges while in their nursing programs, and four themes emerged relating to academics, competing demands, culture, and relationships. Through an awareness of the unique needs of this student population, educators can develop strategies to improve retention. [

Reconnaissance geological mapping and thematic studies of the Elu Basin, Nunavut
Authors: Rainbird R H , Ielpi A
Published: January 2015

Foreword
The Geo-mapping for Energy and Minerals (GEM) program is laying the foundation for sustainable economic development in the North. The Program provides modern public geoscience that will set the stage for long-term decision making related to investment in responsible resource development. Geoscience
knowledge produced by GEM supports evidence-based exploration for new energy and mineral resources and enables northern communities to make informed decisions about their land, economy and society. Building upon the success of its first five-years, GEM has been renewed until 2020 to continue
producing new, publically available, regional-scale geoscience knowledge in Canada's North.
During the summer 2014, GEM's new research program has been launched with 14 field activities that include geological, geochemical and geophysical surveying. These activities have been undertaken in collaboration with provincial and territorial governments, northerners and their institutions,
academia and the private sector. GEM will continue to work with these key collaborators as the program advances.
The Elu Basin Geoscience Project is a sub-activity of the Geology and Mineral Potential of the Chantrey-Thelon Area activity within the Rae Project (led by GSC in collaboration with C-NGO). Its primary focus is to define the main basin depositional elements of the Elu Basin and evaluate its
potential to host stratabound and/or unconformity-type mineralization, particularly of uranium.

Authors: Alvarenga Fábio Augusto de Santi , Pinelli Camila , Loffredo Leonor de Castro Monteiro
Published: January 2015

Objective: The aim of this study was to investigate the reliability of visual and digital methods to assess marginal microleakage in vitro. Materials and Methods: Typical Class V preparations were made in bovine teeth and filled with composite resin. After dye penetration (0.5% basic fuchsin), teeth were sectioned and the 53 obtained fragments were assessed according to visual (stereomicroscope) and digital methods (Image Tool Software®-ITS) (University of Texas Health Science Center-San Antonio Dental School, USA). Two calibrated examiners (A and B) evaluated dye penetration, by means of a stereomicroscope with ×20 magnification (scores), and by the ITS (millimeters). The intra- and inter-examiner agreement was estimated according to Kappa statistics (κ), and intraclass correlation coefficient (ρ). Results: In relation to the visual method, the intra-examiner agreement was almost perfect (κA = 0.87) and substantial (κB = 0.76), respectively to the examiner A and B. The inter-examiner agreement showed an almost perfect reliability (κ = 0.84). For the digital method, the intra-examiner agreement was almost perfect for both examiners and equal to ρ = 0.99, and so was the inter-examiner agreement value. Conclusion: Visual (stereomicroscope) and digital methods (ITS) showed high levels of intra- and inter-examiner reproducibility when marginal microleakage was assessed.

Authors: Ok Evren , Adanir Necdet , Hakki Sema
Published: January 2015

Objective: The purpose of this in vitro study was to compare the cytotoxicity of 0.5–4.5 origanum extract solution (OES), 2% chlorhexidine gluconate (CHX) and 5.25% sodium hypochlorite (NaOCl) with WST-1 test on human periodontal ligament (hPDL) fibroblasts. Materials and Methods: About 0.5–4.5% OES, 2% CHX and 5.25% NaOCl solutions cytotoxicity was evaluated with cell culture test using PDL fibroblasts. Viability of hPDL cells was evaluated with WST-1 (Cell Proliferation Reagent WST-1 Roche) test at 1, 24 and 72nd h. hPDL cells were plated at 20 × 103 cells per well in 96-well plates. Absorbance values were read in optical density 480 nm by ELISA plate reader spectrophotometer. The statistical differences between various groups were evaluated using one-way ANOVA, post-hoc Duncan's Multiple Range test using SAS software. Statistically, a significant difference was considered at P < 0.001. Results: According to the 1-h cytotoxicity results, 0.5% OES showed the least cytotoxic effect in test groups. There were not found any statistical significance between 1% OES and 2% CHX. About 5.25% NaOCl showed more cytotoxic effect than 1% OES and 2% CHX. In 24 and 72 h, different concentrations of OES, 5.25% NaOCl, 2% CHX solutions showed similar cytotoxic effect. Conclusions: Based on these results, 1% OES and 2% CHX showed similar results and less cytotoxic effect than 5.25% NaOCl. It could be considered as a favorable solution concentration when OES was used as root canal irrigation solution.

Authors: Erdemir Ebru Olgun , Hendek Meltem Karsiyaka , Keceli H. Gencay , Apan Teoman Z.
Published: January 2015

Objective: The aim of this study is to evaluate the influence of regenerative periodontal therapy on clinical parameters and interleukin-8 (IL-8), IL-17 and soluble intercellular adhesion molecule-1 (sICAM-1) levels in gingival crevicular fluid (GCF) of subjects with chronic periodontitis (CP). Materials and Methods: Fifteen patients received demineralized freeze-dried bone allograft (DFDBA) surgically to the site of infrabony defect. Clinical periodontal indices were recorded, and GCF samples were collected at baseline and at the 6th and the 9th month after the surgery. Results: Except plaque index, all clinical parameters improved following surgery (P < 0.05). The volume of GCF diminished from baseline to follow-up periods (P < 0.05). However, no effect was observed on the total amount of IL-8, IL-17 and sICAM-1 in GCF. Conclusion: DFDBA improved clinical outcome in CP subjects and was effective on decreasing the volume of GCF, but no effect was determined on IL-8, IL-17 and sICAM-1. Findings did not indicate a direct relationship between biochemical parameters and periodontal healing after demineralized freeze-dried bone grafting.

Authors: Pintado-Palomino Karen , Tirapelli Camila
Published: January 2015

Objective: This study aimed to evaluate in vitro the effect of formulations containing Biosilicate to treat enamel and dentin bovine samples exposed to dental bleaching agents. Materials and Methods: On enamel and dentin bleached with commercial gels containing 16% carbamide peroxide (CP) (14 days/4 h) or 35% hydrogen peroxide (single session/45 min), desensitizing dentifrices (Sensodyne®; experimental dentifrice of Biosilicate®; Odontis RX®; Sorriso®) were applied along 14 days and desensitizing pastes (Biosilicate®/water 1:1; Dessensebilize NanoP®; Bioglass type 45S5/water 1:1) were applied on days 1, 3, 7, 10 and 14. Distilled water was the control. Microhardness (MH) and roughness measurements were the variables measured on the samples before and after the treatments. Student's t-test analyzed differences before and after the treatments. Two-way analysis of variance and post-hoc Tukey test analyzed differences among the factors desensitizing, bleaching agents and substrate. Results: Tukey test showed no differences in roughness for both bleaching treatments and among the desensitizing agents (P > 0.05). Differences in MH appeared on enamel treated with in-home bleaching when control group (lower values) was compared with Sensodyne, Biosilicate dentifrice, Biosilicate paste, and Bioglass paste (higher values). Comparisons between desensitizing agents on dentin treated with both bleaching gels showed no statistical differences. Conclusions: The effect of formulations containing Biosilicate (Biosilicate dentifrice and paste) was significant in the MH of enamel bleached with 16% CP.
Interleukin-1 receptor antagonist levels in gingival crevicular fluid and serum in nonsmoking women with preterm low birth weight and intrauterine growth retardation
Authors: Kayar Nezahat Arzu , Alptekin Nilgun Ozlem , Haliloglu Seyfullah
Published: January 2015

Objective: The aim of this study was to evaluate interleukin (IL)-1 β and IL-1 receptor antagonist (IL-1ra) levels in gingival crevicular fluid (GCF) and serum (S) in nonsmoking women with normal birth (NB), preterm low birth weight (PLBW), and intra-uterine growth retardation (IUGR). Materials and Methods: In this unmatched case-control study design, 64 women with NB, 45 women with PLBW, and 47 women with IUGR were recruited within 24 h delivery. Clinical periodontal parameters were recorded. IL-1 β and IL-1ra levels in GCF (pg/30 s) and serum (pg/ml) of were evaluated using commercial enzyme immunoassay and ELISA kits. Results: Greater pocket depth and clinical attachment loss were observed in PLBW and IUGR women than in NB women (P < 0.05). The total amounts of IL-1ra and IL-β of GCF were higher levels in NB women than PLBW and IUGR women (P < 0.05). The lowest total amount of IL-1ra of GCF was found in IUGR women (P < 0.05). The concentrations of IL-1ra in serum samples were not statistically significant for any of the study groups (P > 0.05). Conclusion: It can be suggested that worse periodontal conditions and the low levels of IL-1ra in GCF may be an important factor in adverse pregnancy outcomes.

Authors: Tornero Eduard , Martínez-Pastor Juan C. , Bori Guillem , García-Ramiro Sebastián , Morata Laura , Bosch Jordi , Mensa Josep , Soriano Alex
Published: January 2015

Purposes

The aim of the present study was to evaluate the importance of isolated microorganisms according to the Gram stain and the type of antibiotic received on the outcome of early prosthetic joint infection (PJI) treated with debridement, antibiotics and implant retention (DAIR).

Methods

From January 1999 to December 2009, all patients with an early PJI were prospectively registered in a database and they were retrospectively reviewed for this study.

Results

During the study period, 160 patients met the inclusion criteria of the study. After a mean (SD) post-debridement follow-up of 5.2 (2.5) years, 117 patients (73.1%) were considered to be in remission and 43 (26.9%) were classified as failure. Variables associated with failure were liver cirrhosis (66.7% vs. 22.8%, p=0.001), diagnosis within the first 30 days from arthroplasty (30.4% vs. 8.0%, p=0.020), C-reactive protein (CRP) >12 mg/dl (46.7% vs. 21.2%, p=0.005), microorganism isolated in all deep samples (31.1% vs. 16.0%, p=0.047) and Gram-negative (GN) infection not treated with a fluoroquinolone (57.1% vs. 20.0%, P=0.004). Gram-positive (GP) infection not treated with rifampin was close to be statistically significantly associated with failure (34.4% vs. 19.2%, p=0.067). A multivariate analysis identified liver cirrhosis (OR: 12.4 CI95%: 3.1-49.7, p<0.001), CRP-value (OR: 1.06 CI95%: 1.0-1.11, p=0.049), and when a GN-infection was not treated with a fluoroquinolone (OR: 6.5, CI95%: 1.8-23.8, p=0.005) as independent predictors of failure.

Conclusion

The remission rate of PJI treated with DAIR after 3 years of follow-up was 73%. The main predictors of failure were liver cirrhosis, the selected antibiotic most specially fluoroquinolones for GN and rifampin for GP infections, the C-reactive protein and the number of samples culture positive as a potential surrogate markers of bacterial density.
L’alimentation moderne pour la famille traditionnelle : les discours sur l’alimentation au Québec (1914-1945)
Authors: Durand Caroline
Published: January 2015

Cet article explore comment, entre 1914 et 1945, les médecins, les gouvernements provincial et fédéral et les compagnies de transformation alimentaire ont combiné des valeurs traditionnelles et modernes pour diffuser certaines conceptions des rôles féminins, de la famille, de l’individu et du corps. Nous y décrivons les relations entre tradition et modernité dans deux types de discours argumentatifs et normatifs sur l’alimentation et la nutrition parus au Québec, soit les publications gouvernementales et les publicités parues dansLa Revue moderne. Nous estimons que la technologie, la science et la rationalité ont modernisé certaines pratiques alimentaires et perceptions du corps et de la personne mais qu’une continuité a été assurée par l’usage d’images traditionnelles de la femme, de la famille et de la nation. En préservant des conceptions traditionnelles de la féminité et en s’inscrivant dans le discours nationaliste, les textes et les images sur l’alimentation ont facilité la diffusion d’idéaux rationalistes, matérialistes et productivistes. Cela a contribué à la construction sociale du corps et de l’individu modernes et participé à la diffusion de valeurs individualistes et libérales, sans menacer les fondements de la famille patriarcale et de la nation canadienne-française.

Case report on cherubism: non-familial variant
Authors: Arora Shelly , Urs Aadithya B. , Augustine Jeyaseelan , Kumar Priya , Singh Ashi
Published: January 2015

Introduction: Cherubism is a rare, non-neoplastic, self-limiting, fibro-osseous disease, characterized by painless expansion of the maxilla, mandible or both. It usually develops in the first and second year of life. The radiographic appearance presentation is ordinarily bilateral, multilocular appearance in the mandible. To the best of our knowledge, very few cases (less than ten) of non-familial cherubism have been reported in the English literature. Objective: To describe non-familial case of cherubism in a 10-year-old child. Materials and methods: The current case was clinically, radiographically and histopathologically analysed for confirmatory diagnosis. Results: H & E stained section showed vascular and cellular stroma containing numerous multinucleated giant cells. Conclusion: Correlating radiographically and histopathologically the case was finally diagnosed as non-familial variant of cherubism.
Normative and perceived orthodontic treatment need of senior year dental students
Authors: Adebanke Kolawole Kikelomo , Olatunde Agbaje Hakeem , Donald Otuyemi Olayinka
Published: January 2015

Objective: The purpose of this study was to determine perceived and normative orthodontic treatment need of senior year dental students using the Index of Orthodontic Treatment Need (IOTN) and Dental Aesthetic Index (DAI). Materials and Methods: Ninety-nine senior year students of the Faculty of Dentistry, Obafemi Awolowo University Ile-Ife, Nigeria, participated. Normative assessment of occlusal characteristics was car¬ried out using IOTN and DAI while the Aesthetic Component (AC) scale of IOTN was used by the students to assess perceived need. Results: With the AC scale of IOTN, 6.1% of the students expressed “borderline need” and 2% “great need” for treatment, while normative need was 41.4% for “borderline need” and 11.1% for “great need”. The Dental Health Component found 37.4% and 24.2% in these categories, respectively. The DAI gave 26.3%, 13.1% and 15.1% in the elective treatment, highly desirable treatment and mandatory treatment categories respectively. No gender-dependent differences were found. Moderate correlation was observed between perceived and normative need (r=0.643), which was significant (p<0.001). Conclusions: Over half of the dental students had orthodontic treatment need with both indices. Normative and perceived treatment need differed significantly. The perception of treatment need is not only influenced by knowledge and severity of malocclusion, as psychosocial factors acting on individuals may be involved.

Objectives: The significance of microorganisms in root canals with regard to the aetiology of periapical infection and the need for crucial bacteria control during treatment are undeniable. In this study, we re-port and discuss a review of the literature on Microbiological Root Canal Sampling (MRS). The procedure is analyzed in detail, discussing its powers, limitations and the influence of sample collection procedures on the incidence of true and false positive results. Data sources: MEDLINE/PUBMED, B-On and library files of Oporto University were accessed. Selection: Papers were selected using the keywords: “root ca¬nal sampling”; “apical periodontitis”; “endodontic pathogens”; “root canal infection”; “Culture”; “molecular biology”. The references were selected under inclusion criteria such as English language, accessibility, rel¬evance to the theme and scientific rigor. Conclusions: This review illustrated the absolute need to adhere to strict methodology procedures if valid samples are to be obtained. A combination of Culture and molecular identification approaches have confirmed the polymicrobial nature of endodontic infections with a pre¬dominance of anaerobic bacteria. Nucleic acid-based techniques provide significant additional information particularly regarding the not-yet-cultivable species of the microbial community, but greatly increase the budget of the procedure. Thus, assessment of the endodontic microflora, in the context of a polymicro¬bial biofilm ecosystem, and its relevance to endodontic treatments must rely in the complementariness of Culture and Metagenomics approaches as they are neither mutually exclusive nor competitive, but strongly complementary.

Published: January 2015

Introduction: The side effects and adverse reactions related to cancer therapies may cause significant alterations in the oral cavity, discomfort or even severe pain in parts of the body, patient’s nutritional deficiency, delay in the administration of oncologic drugs or dose limitation, an increase of hospitalization time and of the related expenses, as well as a decrease in the patient’s quality of life. Objective: The purpose of this study was to determine the deleterious effects of cancer therapies in the oral cavity. Material and methods: Data was gathered from medical records of the treatment of 643 cancer patients at the São José Hospital, in Joinville, state of Santa Catarina, from January to September 2012. Among the records selected for this study, 59.41% were female patients, with a mean age of 51 to 60 years. Results: Oral complications were reported in 72.47% of the patients, and the complication with the highest prevalence was mucositis (14.62%) followed by dry mouth (10.58%). Most of the patients had not received dental care prior to the cancer treatment, and no dental record was found. Conclusions: Several different oral disorders were reported as a result of cancer treatment, and a significant number of patients needed dental evaluation prior to the treatment.

Objective: This study aimed to identify E. faecalis in saliva of patients that were divided into two groups: 10 patients with caries lesions and 10 caries-free patients. Material and methods: Saliva samples were collected with a sterile swab and inoculated in enterococcosel media for 48 hours. The positive samples were subcultured in broth agar - blood medium for storage and subsequent PCR analysis. The data were analyzed using the SPSS (χ2). Results: From the 20 cases included in the study, 3 were positive in the Enterococcosel medium, and both tests (culture and PCR) used confirmed that three of them belonged to the species E. faecalis. No samples were positive in Enterococcosel broth in the group of caries-free patients. From the three samples that were identified as Enterococcus in broth (positive bile esculin test), an amplified for E. faecalis PCR analysis (p > 0.005). Conclusion: Through the use of PCR, it was possible to identify the genus Enterococcus and the species E. faecalis in saliva of patients with carious lesions – the pathogen that may influence the prognosis of diseases of the oral cavity.

Published: January 2015

Objetivo: O herpes-zóster é uma infecção viral causada pela reativação do vírus da varicela-zóster. Esta doença pode afetar pacientes imunossuprimidos e caracteriza-se por lesões papulovesiculares distribuídas na região inervada pelo nervo afetado, causando dores intensas. Este artigo relata o caso de um paciente do sexo masculino, leucoderma, 26 anos de idade, dependente químico, HIV positivo e com tuberculose ganglionar que procurou o Hospital Oswaldo Cruz (Curitiba/PR) tendo como queixa mal-estar geral, lesões na pele e mucosa oral, e linfadenopatia na região cervical. Discussão: O diagnóstico do herpes-zóster foi estabelecido por meio das características clínicas das lesões, e o tratamento estabelecido envolveu o uso de drogas antirretrovirais, analgésicos e antidepressivos. Conclusão: O cirurgião-dentista precisa estar atento às lesões papulovesiculares que acometem a pele e as mucosas de forma unilateral, acompanhadas de sin¬tomas de prurido e dor, pois elas garantem o diagnóstico do herpes-zóster.
Cidade como metáfora de si: representação socioespacial de Cuiabá-MT segundo a criança
Authors: M. P. da Silva Eliza , B. da S. F. Andrade Daniela
Published: January 2015

Este artigo propõe uma discussão sobre a relação da criança com a cidade, mediante análise compreensiva do discurso associado ao mapa da cidade construído pela criança participante, com o objetivo de refletir sobre aspectos de sua constituição identitária nessa relação. A análise das significações se orienta pela articulação entre a Teoria Histórico-Cultural (VIGOTSKI, 2009, 2010) e a Teoria das Representações Sociais (MOSCOVICI, 2003), esta última no diálogo com os estudos de Jodelet (1982, 2001). Os estudos de Tuan (1980, 1983) sobre a noção de lugar, topofilia e topofobia também integram o referencial teórico, que, em seu conjunto, possibilita compreender a relação entre criança e cidade como aspecto importante para o desenvolvimento infantil. O procedimento metodológico adotado para a apreensão da representação socioespacial deu-se pelo recolhimento do desenho da cidade, inspirado na proposta dos mapas cognitivos (ALBA, 2011), acompanhado de entrevista semiestruturada com uma criança de uma escola municipal de Educação Básica de Cuiabá, MT. A análise da entrevista e do mapa da cidade orientou-se pela perspectiva compreensiva do discurso e revelou que a representação socioespacial da cidade de Cuiabá é influenciada por valores, vivências e afetos da criança, estando presentes elementos de suas particularidades, mas que também são frutos de relações estabelecidas socialmente. Além disso, nota-se que os lugares do afeto permeiam o processo de formação identitária da criança, aspecto que permite anunciar que, em alguma medida, a cidade é tomada como metáfora de si.

A população de cães domésticos estimada é de 400 milhões de indivíduos para o mundo, 33 milhões para o Brasil e aproximadamente 80 mil para o município de Ponta Grossa. Considerando o elevado número de cães no município e as suas consequências, o presente estudo teve como objetivo conhecer a densidade e a distribuição espacial da população canina encontrada no câmpus de Uvaranas da Universidade Estadual de Ponta Grossa — UEPG, em Ponta Grossa, PR, além de peculiaridades da população, relacionando-as com a movimentação demográfica local. Utilizou-se o método de estimativa do tamanho total da população, por meio de contagem direta em campo e memorização das coordenadas geográficas referentes a cada um dos pontos de encontro dos animais, além da coleta de outras informações pertinentes. Durante a pesquisa, foi constatada a presença de 35 indivíduos no ano de 2009 e 46 no ano de 2011 na área de estudo. Os resultados obtidos comprovam a superpopulação de cães abandonados na área de estudo e servem como subsídio aos órgãos responsáveis para reflexões e futuras intervenções.

Published: January 2015

Levels of heavy metals (mercury, chromium, lead, cadmium and iron) in the water snail (Pilaovata) in the river nun downstream of Yenegoa Town, south-south Nigeria and other parameters (temperature, ph,turbidity, Total Dissolved Solids TDS, oil and grease) in the water column was investigated in an attempt to understand the impact of urbanization and poor waste management practices on downstream communities in non-oil impacted communities in the Niger delta of Nigeria. While mercury was very minute, iron and chromium where within standards for food in the snail, lead (26-27.4 mg/l), cadmium (12.11--12.16 mg/l) and arsenic (6.92-8.41mg/l) concentrations where above the standards for food sources. Turbidity in the water column was above recommended levels for drinking water, aesthetics and aquatic health. The study concludes that the area may also have lost its capacity to support good fish production, and the water source has become a dangerous source of food and water to inhabitants due to hydrocarbon and heavy metal concentrations. Government intervention and environmental education is recommended.

O objetivo deste trabalho foi identificar os odonatos associados a Eichhornia crassipes (Mart.), assim como investigar as principais variáveis ambientais que afetam a sua distribuição espacial no Rio Uruapiara, Amazonas, Brasil. As macrófitas foram amostradas com um quadrado vazado com área total de 0,120 m2. A remoção das larvas foi realizada mediante lavagem da planta com água gaseificada. Foram avaliadas as seguintes variáveis ambientais: temperaturas do ar e da água, oxigênio dissolvido, pH, turbidez, fósforo total e nitrogênio total. Um total de 73 larvas de Odonata, distribuídas nas famílias Libellulidae (64) e Coenagrionidae (9) foram identificadas. Libellulidae esteve representada por Erythemis, Micrathyria, Tauriphila e Nephepeltia e Coenagrionidae por Acanthagrion e Oxyagrion. A análise de correspondência canônica (ACC) mostrou que Tauriphila e Coenagrionidae foram afetadas positivamente pela concentração do oxigênio dissolvido na água. Nephepeltia e Oxyagrion foram afetados negativamente com o aumento do oxigênio dissolvido. O estudo revelou que o oxigênio foi o fator mais significativo na distribuição de larvas de Odonata no rio Uruapiara.

Poluentes persistentes lançados no leito dos rios retornam ao sistema trófico danificando os organismos que o integram. O objetivo deste trabalho foi avaliar a qualidade dos sedimentos de áreas localizadas junto a curtumes e impactadas por múltiplos contaminantes. Para isto foram desenvolvidos ensaios crônicos (21 dias), semiestáticos utilizando Daphnia magna como organismo-teste. Foram expostos 520 indivíduos, a amostras coletadas entre maio de 2001 e março de 2002, para avaliar alterações na sobrevivência e na reprodução destes microcrustáceos. Como ambiente para o desenvolvimento dos testes foram utilizados sedimento e meio de cultivo M4 na relação de 1 : 4 (v : v), dispostos em béqueres de 50 mL. Cada béquer recebeu um microcrustáceo (LC 50-24h = 0,97 mg . L-1 K2Cr2O7 ± 0,04 mg . L-1) totalizando dez réplicas por amostra. Os ensaios foram desenvolvidos em condições controladas de iluminação (16h luz diárias) e temperatura (20 ± 2 ºC). A reprodução dos microcrustáceos em amostras dos rios Cadeia e Feitoria foi inferior ao esperado, em todas as amostragens, o mesmo ocorrendo com as amostras de seus afluentes. O Teste de Duncan mostrou variação na reprodução (p < 0,05) tanto nos rios quanto em seus os afluentes. Os dados indicam presença de toxicidade crônica no ecossistema avaliado.
