Clavicle pain and reduction of incisional and fascial pain after posterior cervical surgery
Authors: Duetzmann Stephan , Cole Tyler , Senft Christian , Seifert Volker , Ratliff John Kevin , Park Jon 
Published: August 2015

OBJECT
Incisional pain after posterior cervical spine surgery can be severe and very unpleasant to the patient. Ongoing incisional pain is one of the key disadvantages of posterior over anterior surgical approaches to the cervical spine. It prolongs hospital stays and delays return to work. In this study, the hypothesized that incisional pain in the immediate postoperative period is caused partially by tension on the skin as well as on the deep cervical fascia and the fascia overlying the trapezius, which are usually sewn together during closure. Reduction of this tension through retraction of the shoulders should therefore reduce pain as well as the amount of pain medication used in the early postoperative period.

METHODS
In this prospective randomized controlled study, 30 patients who had undergone posterior cervical spine surgery were randomized into 2 groups who either wore or did not wear a clavicle brace to retract the shoulders. Patients in the brace group began wearing the brace on postoperative day (POD) 4 and wore it continuously throughout the 30-day study period. Outcome was assessed by two measures: 1) the daily level of self reported pain according to the visual analog scale (VAS) and 2) the number of pain pills taken during the 30-day postoperative period.

RESULTS
Wearing a clavicle brace in the immediate postoperative period significantly reduced incisional pain and the amount of pain medication that patients took. Beginning on POD 4 and continuing until day POD 13, the mean daily VAS score for pain was significantly lower in the brace group than in the control group. Furthermore, patients who wore the clavicle brace took less pain medication from POD 4 to POD 12. At this point the difference lost significance until the end of the study period. Four patients were randomized but did not tolerate wearing the brace.

CONCLUSIONS
Patients who tolerated wearing the clavicle brace after posterior cervical spine surgery had reduced pain and used less pain medication.
Sagittal plane lumbar intervertebral motion during seated flexion-extension radiographs of 658 asymptomatic nondegenerated levels
Authors: Staub Blake N. , Holman Paul J. , Reitman Charles A. , Hipp John 
Published: August 2015

OBJECT
Evaluation of lumbar stability is fundamentally dependent on a clear understanding of normal lumbar motion. There are inconsistencies in reported lumbar motion across previously published studies, and it is unclear which provide the most reliable reference data. New technology now allows valid and reliable determination of normal lumbar intervertebral motion (IVM). The object of this study was to provide normative reference data for lumbar IVM and center of rotation (COR) using validated computer-assisted measurement tools.

METHODS
Sitting flexion-extension radiographs were obtained in 162 asymptomatic volunteers and then analyzed using a previously validated and widely used computerized image analysis method. Each lumbar level was subsequently classified as “degenerated” or “nondegenerated” using the Kellgren-Lawrence classification. Of the 803 levels analyzed, 658 were nondegenerated (Kellgren-Lawrence grade < 2). At each level of the lumbar spine, the magnitude of intervertebral rotation and translation, the ratio of translation per degree of rotation (TPDR), and the position of the COR were calculated in the nondegenerative cohort. Translations were calculated in millimeters and percentage endplate width.

RESULTS
All parameters were significantly dependent on the intervertebral level. The upper limit of the 95% CIs for anteroposterior intervertebral translation in this asymptomatic cohort ranged from 2.1 mm (6.2% endplate width) to 4.6 mm (13.3% endplate width). Intervertebral rotation upper limits ranged from 16.3° to 23.5°. The upper limits for TPDR ranged from 0.49% to 0.82% endplate width/degree. The COR coordinates were clustered in level-dependent patterns.

CONCLUSIONS
New normal values for IVM, COR, and the ratio of TPDR in asymptomatic nondegenerative lumbar levels are proposed, providing a reference for future interpretation of sagittal plane motion in the lumbar spine.
The effect of velocity and familiarisation on the reproducibility of isokinetic dynamometry
Authors: Nugent Erin P. , Snodgrass Suzanne J. , Callister Robin 
Published: August 2015

BACKGROUND: The reproducibility of the HUMAC-NORM isokinetic dynamometer has not yet been established for the muscles around the knee. Previous research suggests practice-based improvement (PBI) may impact upon the reproducibility of isokinetic testing. OBJECTIVE: To investigate test-retest reproducibility of knee flexion and extension isokinetic findings at different velocities, including the influence of familiarisation. METHODS: Seventy physically active, healthy participants with no experience in isokinetic dynamometry performed five repetitions of continuous concentric knee flexion and extension at 60, 120, 180 and 240°/s on four occasions. Peak moment, angle of peak moment, total work and average power were recorded. Reproducibility was determined using percentage change in the mean, typical error and intraclass correlation coefficients(ICC). RESULTS: For knee flexion and extension, group data met desirable reproducibility criteria for most outcomes and velocities after Trial 2. Within-subject reproducibility generally met acceptable reliabilty criteria after Trial 2 for knee extension, but was predominantly unacceptable for knee flexion. ICC's were acceptable from Trial 2, except for angle of peak moment which did not achieve an acceptable level of reliabilty across any trials, outcomes or velocities. CONCLUSIONS: The HUMAC-NORM demonstrates excellent reproducibility for peak moment, average power and total work parameters for the major knee muscles after one trial. One familiarisation session is recommended prior to testing to minimise the impact of PBI. Additional familiarisation is beneficial when testing individuals, higher velocities and knee flexion.
Mining libraries: Lessons learned from 20 years of massive computing on the world’s information
Authors: Leetaru Kalev Hannes 
Published: August 2015

Abstract Over the course of the last two decades I have explored the informational undercurrents of the world’s information and the potential of mass data mining of libraries through a myriad of lenses, both technical and methodological. From founding my first Internet startup twenty years ago as an eighth grade middle school student, to running one of the world’s largest global monitoring platforms today, my work has debuted a myriad of new datasets, methodologies, and scales to the study of how we understand our global world. A central theme of that work has been around how creative “reimagining” of information through the emerging world of massive computing power can offer powerful and unexpected new lenses onto the world around us, and the incredible future that awaits as libraries transition from being museums of artifacts to becoming conveners of information and innovation that empower a new era of access and understanding of our world. This paper offers a unique detailed view of what it looks like deep in the trenches of the data revolution, surveying a selection of my projects over the last two decades and the lessons they offer libraries and publishers moving forward into our data-driven future.
A first test of elemental allelopathy via heterospecific pollen receipt
Authors: Wipf Heidi M.‐L. , Meindl George A. , Ashman Tia‐Lynn 
Published: August 2015

PREMISE OF THE STUDY:Coflowering plants often share pollinators and may receive mixed species pollen loads. Although detrimental effects of heterospecific pollen receipt have been documented, trait‐based modifiers of interactions on the stigma remain largely unknown. Chemicals that mediate interactions between sporophytes could also influence pollen–pollen or pollen–style interactions. We test for the first time whether nickel (Ni) accumulation in pollen can lead to “elemental allelopathy” and intensify the fitness consequences of heterospecific pollen receipt.METHODS:We grew Ni‐hyperaccumulator Streptanthus polygaloides in soils augmented with three concentrations of Ni, measured pollen Ni concentration, and hand‐pollinated non‐Ni hyperaccumulator Mimulus guttatus. We assayed pollen germination, tube growth and seeds of M. guttatus after pure and mixed species pollinations.KEY RESULTS:Streptanthus polygaloides pollen accumulated Ni in proportion to soil availability and at levels significantly greater than M. guttatus pollen. Although receipt of S. polygaloides pollen increased M. guttatus pollen germination, it decreased the proportion of pollen tubes reaching the ovary and seed number. Increased Ni in pollen, however, did not significantly intensify the effect of S. polygaloides pollen receipt on M. guttatus seed production.CONCLUSIONS:Different levels of Ni in the pollen of S. polygaloides achieved in the greenhouse did not significantly reduce the fitness of M. guttatus. Stigma tolerance to Ni may also have contributed to the lack of response to increased Ni in heterospecific pollen. This study paves the way for additional tests in other metal hyperaccumulators and recipients, and to identify mechanisms of interactions on the stigma.
Donor Unrestricted T Cells: A Shared Human T Cell Response
Authors: Van Rhijn Ildiko , Moody D. Branch 
Published: August 2015

Abstract
The now-famous term “restriction” derived from experiments in which T cells from Donor A failed to recognize Ags presented by cells from Donor B. Restriction results from interdonor variation in MHC genes. Donor restriction dominates immunologists’ thinking about the T cell response because it governs organ transplantation and hinders the discovery of disease-associated Ags. However, other T cells can be considered “donor unrestricted” because their targets, CD1a, CD1b, CD1c, CD1d, or MR1, are expressed in a similar form among all humans. A striking feature of donor unrestricted T cells is the expression of invariant TCRs with nearly species-wide distribution. In this article, we review new evidence that donor unrestricted T cells are common in humans. NKT cells, mucosa-associated invariant T cells, and germline-encoded mycolyl-reactive T cells operate outside of the familiar principles of the MHC system, providing a broader picture of T cell function and new opportunities for therapy.

Published: August 2015

ABSTRACTVerrucous carcinoma (VC) of oral cavity is a rare variant of well-differentiated squamous cell carcinoma and squamous papilloma is a benign proliferation of the stratified squamous epithelium, which results in a papillary or verrucous exophytic mass. There is a certain clinical similarity between squamous cell papilloma and VC. We presented a report of two cases which are VC and squamous cell papilloma that are showed the same clinical appearance but different pathological appearance, with a review of the literature.

Published: August 2015

ABSTRACT
Objective: To test the hypothesis that maxillary development may be affected by occlusal support. Materials and Methods: The sample was composed by Wistar rats (5 weeks old) divided into three groups: Control (n = 10), extraction of mandibular molar teeth – left side (n = 10), extraction mandibular molar teeth – left and right sides (n = 10). The rats were sacrificed 8 weeks postextraction. Cone beam computed tomography scan images were taken for posterior measurement of maxillary length and width. Data were analyzed by one-way analysis of variance (Tukey test as post-hoc test). Results: Maxillary length was significantly shorter (P < 0.005) in both groups after tooth extraction. No difference was observed regarding maxillary width and body weight. Conclusion: Reduced occlusal support may impair the development of the maxilla in rats.

Published: August 2015

ABSTRACTReplacement of missing ears is a challenging task in which extensive array of materials and techniques have been employed. This article describes a different and simplified procedure for fabricating auricular prostheses very similar to the intact left ear of the patient. A 65-year-old male patient was referred to the Department of Prosthodontics with the loss of the right ear. In this case, the impression was made using hydrocolloid material (alginate) from the both defected and the opposite side. After hardening of the stone casts, a custom-made transparent splint plate was designed for the left auricular side. The splint was reversed and a cast model of the right auricular side was obtained as pouring the dental stone into transparent orthodontic splint. After getting the impression from cast model, conventional wax pattern and try on process was done. Finally, silicone elastomer was polymerized and the retention of the prosthesis acquired with the magnetic attachments. The technique described is economical, conventional, and time-saving. Furthermore, the prosthesis imitates the patient's intact auricular tissue.

Authors: Ibrahim Haifaa Mohamed , Awooda Elhadi Mohieldin 
Published: August 2015

Abstract
Aim: To assess patient perception toward male or female dentists, whether gender stereotyping of dentists offering dental treatment played a role. The study then went further to investigate if patients reacted differently toward the dentist′s gender when placed in certain situations. Materials and Methods: This study was conducted in Academy Dental Teaching Hospital, the total number of participants was 384 adult over 18 years male and female their number was equally divided. Data were collected by the use of a self-administered questionnaire. Questions were closed ended in which the patient had one of three options: male dentist, female dentist or no difference. The participants with experience of being treated by both a male and female dentist were only included. Data were analyzed using Chi-square test with a level of significance set at P < 0.05. Results: Overall there is no specific dentist gender preference among the studied population. With the decrease in patient′s age an association was found concerning patients perception, the range of 18-39 years showed the highest percentage of preference toward a specific gender. More than half (62.2%) of patients stated that if given the choice, they would not choose a dentist gender of different sex. Conclusion: Gender was not an issue for patients when it came down to the treatment process, and it was however established that patients perceived certain characteristics represented specific dentist genders. Patients felt more relaxed when they were being treated by a female dentist, but felt male dentists showed more confidence during the treatment process.
Enjeux éthiques potentiels liés aux partenariats patients en psychiatrie : état de situation à l’institut universitaire en santé mentale de Montréal
Authors: Lierville Anne-Lise , Grou Christine , Pelletier Jean-François 
Published: August 2015

La participation des usagers des services au profit de l’amélioration de la qualité du système a été érigée en priorité par le Plan d’action en santé mentale de 2005. Dans ce cadre, l’Institut universitaire en santé mentale de Montréal a développé des dispositifs innovants autour du principe de pleine citoyenneté, grâce aux patients partenaires et aux pairs aidants.
Cet article a pour objectif d’interroger, d’un point de vue éthique, à la fois ces pratiques en tant que telles mais également leurs encadrement et accompagnement institutionnels. Cette étude a été réalisée au moyen d’une revue de la documentation scientifique, d’un examen des dispositifs institutionnels associés et d’entretiens axés sur les conditions d’exercice de cette participation.
L’analyse a permis de mettre en lumière la pluralité de réalités que recouvre ce dispositif de participation des usagers. S’il y a consensus sur le potentiel offert par une participation des patients au système de santé, certains facteurs et zones de risque peuvent néanmoins être identifiés : isolement, fatigue émotionnelle, rechute possible, précarité, enjeux d’intégration. Pour éviter de tels écueils, l’étude a souligné la nécessité de préparer, d’accompagner et de soutenir les usagers dans leurs nouvelles fonctions, ainsi que l’importance d’une gouvernance globale de cet ensemble d’activités. Au terme de cette étude, certaines recommandations sont formulées, en particulier celle consistant à réactualiser les valeurs éthiques institutionnelles à la lumière des nouveaux paradigmes de partenariat patient.
Les dispositifs de délibération en santé mentale et la démocratisation des échanges entre les pairs : le cas de l’assemblée des usagers d’un centre d’attention psychosociale au Brésil
Authors: Ruelland Isabelle 
Published: August 2015

Le réseau public de services de santé mentale de la ville de Campinas dans l’État de São Paulo au Brésil est constitué de divers dispositifs de délibération impliquant des personnes utilisatrices. L’assemblée des usagers dans les centres d’attention psychosociale (CAPS) constitue un exemple clé de ce genre d’innovation participative fondée sur des principes de démocratisation et de justice sociale. Est-ce que l’assemblée des usagers comme dispositif délibératif institué agit sur les inégalités sociales de pouvoir et le rétablissement des personnes ? Il s’agit ici de rendre compte de certains résultats d’une recherche qui a pour objectif de saisir si de tels dispositifs agissent sur la démocratisation des rapports sociaux du point de vue des personnes utilisatrices impliquées, et comment. À partir d’une ethnographie organisationnelle de près d’un an dans un CAPS du réseau public de santé mentale de Campinas, il a été constaté comment les échanges créés au sein et en dehors de l’assemblée des usagers participent à l’émergence d’une forme de pair-aidance spontanée et informelle. Ce constat permet de réfléchir sur le rapport entre cette pair-aidance implicite et la circulation des personnes dans une pluralité d’espaces collectifs ouverts dans lesquels celles-ci peuvent partager des affects et critiquer librement au sujet des services reçus.
Le parcours des parents et des enfants présentant un TSA
Authors: Poirier Nathalie , Vallée-Ouimet Jacinthe 
Published: August 2015

Objectif : Cette recherche s’intéresse à l’expérience des parents (n = 41) concernant leur enfant ayant un trouble du spectre de l’autisme (TSA) selon différents thèmes clés de son développement, soit le diagnostic, la santé, la famille, l’intervention, le milieu de garde éducatif, le milieu scolaire, l’âge adulte et la reconnaissance du trouble.
Méthode : Quarante et un parents de personne présentant un TSA ont été recrutés par la Fédération québécoise de l’autisme (FQA) et certains par échantillonnage de convenance afin d’assurer une variabilité quant à la sévérité du trouble. Ils ont ensuite répondu à un questionnaire de 192 questions, couvrant les données signalétiques du répondant, le diagnostic de l’enfant, l’état de santé, l’aspect familial, les services de répit, le milieu de garde éducatif, les interventions, le milieu scolaire fréquenté, la période de l’adolescence, l’âge adulte, les droits et la reconnaissance du trouble. Ce questionnaire a été lu et commenté par dix étudiantes de niveau doctoral en psychologie et par trois experts en TSA afin d’évaluer la pertinence, la justesse et l’étendue des questions. Le questionnaire a été passé à 10 parents dans le cadre d’une étude qualitative et les questions ont été ajustées pour concevoir le questionnaire de la présente étude.
Résultats : Les résultats indiquent que les premières inquiétudes des parents à ce qui a trait au développement de leur enfant concernent le langage, le contact visuel, l’isolement et la motricité. Les parents mentionnent éprouver des émotions positives comme la fierté et la joie ainsi que des émotions négatives telles que l’inquiétude relativement à l’avenir à leur enfant. Quelques familles profitent des services de répit et les parents estiment que les services d’intervention sont insuffisants. Près de la moitié des parents sont satisfaits des services reçus à l’école. La plupart des adultes ayant un TSA habitent toujours avec au moins un de leurs parents. Certains d’entre eux travaillent, mais la rémunération est minimale. Sur le plan de la reconnaissance, une majorité de parents indique qu’ils auraient préféré que leur enfant n’ait pas de TSA afin que la vie de ce dernier soit plus facile.
Conclusion : Les données recueillies permettent une compréhension de l’expérience des parents pouvant servir à l’adaptation des services aux familles d’enfant présentant un TSA. Une plus grande connaissance quant aux services éducatifs en milieu de garde, aux services d’interventions à prodiguer à leur enfant lors de la petite enfance ou en milieu scolaire ainsi qu’aux services pouvant être obtenus sur le plan des répits serait à favoriser afin d’aider les parents à mieux organiser les services de leur enfant.

Pour soutenir l’accès et l’implantation des meilleures pratiques de réadaptation en santé mentale au Québec, le Centre d’études sur la réadaptation, le rétablissement et l’insertion sociale (www.cerrisweb.com) a mis sur pied une communauté de pratique et organisé des activités Web 2.0 accessibles à distance. Dans cet article, les auteures présentent cette communauté de pratique et les résultats d’une expérience de trois années (2010-2013) concernant l’appréciation de ses membres de deux activités Web 2.0 de dissémination et d’échange de connaissances : la conférence en ligne et le débat-blogue. L’utilisation d’outils Web 2.0 semble une avenue intéressante pour faciliter l’accès aux connaissances et favoriser les échanges entre acteurs du réseau de la santé mentale du Québec.
