Quel instrument faut-il choisir pour présenter les résultats d’une évaluation médico-économique d’un médicament ou d’un produit de santé ?
Authors: Launois Robert , Kabeshova Anastasiia
Published: December 2016

Mesurer la santé gagnée d’un traitement innovant nécessite quelques indications et précautions. Le guide de l’utilisateur que prépare actuellement la HAS en vue de la rédaction d’un rapport technique d’évaluation ex ante, recommande de présenter les résultats en termes de courbes d’acceptabilité lorsqu’il n’existe qu’un seul comparateur, en termes de santé gagnée et de frontière d’acceptabilité lorsqu’il en existe plusieurs. Lorsque les évaluations médico-économiques sont conduites en exploitant des données individuelles dans le cadre d’un modèle stochastique, l’incertitude liée à la variabilité interindividuelle et aux fluctuations d’échantillonnage des mesures sont quantifiées à l’aide des intervalles de confiance. Parmi la panoplie d’outils disponibles pour calculer l’intervalle de confiance du ratio coût résultat, le théorème de Fieller et les méthodes non paramétriques de ré-échantillonnage sont les approches à privilégier compte tenu de la précision de leurs estimations. L’économiste ne peut cependant pas ignorer les problèmes que pose l’évaluation du ratio coût-efficacité lorsque les réplications du boostrap sont dispersés dans les quatre quadrants du plan coût efficacité. Les problèmes demeurent lorsque l’incertitude par ignorance est explorée dans le cadre d’un modèle d’analyse de décision. Une démarche bayésienne permet d’associer à chaque paramètre du modèle des distributions de probabilités à partir desquels de multiples tirages pourront être effectués. Dans les deux approches stochastique et décisionnelle, la dérivation de la courbe d’acceptabilité des ratios coût efficacité et l’analyse des gains nets de santé, monétarisés et non monétarisés, permettent de surmonter les difficultés inhérentes au calcul de l’intervalle de confiance d’un ratio. L’objectif de cet article est de procéder à une description de ces outils.
Multi-state models and cost-effectiveness analysis
Authors: Saint-Pierre Philippe
Published: December 2016

Les modèles multi-états permettent d’étudier l’évolution dans le temps d’un phénomène observé à différents moments. Le processus associé est souvent Markovien afin de résumer le passé. Ces modèles sont appliqués avec succès dans différents domaines. Les modèles semi-Markoviens sont une alternative intéressante puisque l’évolution du processus dépend du temps passé dans un état. En effet, la distribution des temps de séjour est exponentielle dans les modèles Markoviens alors que c’est un paramètre du modèle semi-Markovien. Une revue des principales méthodes d’estimation dans ces modèles est présentée. Les modèles Markoviens homogènes avec des intensités constantes et les modèles Markoviens non homogènes avec des intensités dépendantes du temps sont présentés. Une méthode d’estimation paramétrique dans les modèles semi-Markoviens est ensuite proposée. La méthode du maximum de vraisemblance permet d’estimer les paramètres des distributions des temps de séjours. On discute ensuite l’utilisation des modèles multi-états dans les analyses coût-efficacité. En effet, un modèle de coût peut aisément être ajusté pour évaluer les coûts et l’efficacité d’une intervention. L’application de ces modèles au cas de l’asthme permet d’illustrer le potentiel de ces méthodes.

Des collaborations équivoques
Authors: Oberhauser Pierre-Nicolas
Published: December 2016

Lorsqu’ils s’investissent dans des projets de recherche impliquant la mise en place d’une infrastructure numérique dédiée, les chercheurs en sciences humaines et sociales (SHS) sont amenés à collaborer avec des spécialistes des sciences et techniques informatiques (STI). Ces collaborations constituent un aspect important des transformations qu’impliquent les humanités numériques pour la recherche en SHS. Cet article en identifie certaines caractéristiques à partir d’un travail de terrain ethnographique auprès d’une équipe de recherche en psychologie du développement rattachée à un laboratoire d’humanités numériques. Nous décrivons dans un premier temps la vigilance qu’impliquent ces collaborations pour les chercheurs, qui sont régulièrement amenés à s’interroger sur la qualité des contributions des spécialistes en STI avec lesquels ils collaborent et sur leur adéquation aux objectifs poursuivis par le projet. Dans un second temps, nous revenons sur les efforts de planification déployés par les chercheurs pour assurer le bon déroulement du projet. Nous montrons comment ces efforts s’appuient de manière prépondérante sur les informations transmises par les spécialistes en STI et cherchons à éclairer les conséquences de cette dépendance épistémique. Le matériau analysé consiste en des entretiens semi-directifs avec les membres de l’équipe, des observations ethnographiques de situations de travail et des enregistrements vidéo de réunions rassemblant les différents participants au projet.

An Anatomical Study on the Safe Placement of Orthopedic Hardware for Syndesmosis Fixation
Authors: Shuler Franklin D. , Woods Daniel , Tankersley Zach , McDaniel Clint , Hamm Jacob , Jones Justin , Denvir James , Czarkowski Brian
Published: December 2016

Articular cartilage and bony contact at the distal tibiofibular cartilage contact zone (TFCCZ) is variable. The appropriate placement of syndesmotic hardware would benefit from a more accurate characterization of the proximal extent of the TFCCZ allowing surgeons to place hardware that simultaneously improves biomechanical stability and decreases the risk of iatrogenic cartilage damage. In addition, Ilizarov wire fixation through the distal fibula and tibia can pass through the syndesmosis recess. Anatomically defining the proximal extent of this recess can help decrease the risk of inadvertent capsular penetration. This study anatomically defines the TFCCZ and syndesmosis recess establishing a safe and biomechanically advantageous distance from the plafond for orthopedic fixation. This study measured the height of the TFCCZ and the syndesmotic recess in 3158 anatomical and cadaveric specimens. A TFCCZ was present in 59% of the Robert J. Terry Anatomical Collection specimens. Maximal height of the TFCCZ averaged 5.7±1.7 mm (99% confidence interval [CI], 5.6–5.8 mm) for anatomical specimens and 5.6±1.6 mm (99% CI, 4.6–6.5 mm) for cadaveric dissections. The maximum TFCCZ height was 11.71 mm. Maximal height of the syndesmotic recess averaged 12.8±2.1 mm for anatomical specimens and 13.7±2.7 mm for cadaveric specimens. The “3 cm rule” appears to be appropriate for fine wire fixation accounting for capsular distension that can be associated with injuries but not applicable for syndesmotic fixation. There is a less than 0.1% chance of encountering the TFCCZ cartilage at 10.9 mm above the plafond and a less than 0.01% chance at 12 mm above the plafond. [

A Young Adult with Unintentional Acute Parenteral Iron intoxication Treated with Oral Chelation: The Use of Liver Ferriscan.
Authors: De Sanctis Vincenzo
Published: December 2016

Acute iron poisoning in humans has not been adequately studied. Toxicity depends on the severity of iron overload. Manifestation of acute iron poisoning, defined as a serum iron concentration >300 µg/dL (55 µmol/L) within 12 hours of ingestion, by oral route include numerous symptoms which appear in progressive stages.  Systemic toxicity is expected with an ingestion of 60 mg/kg.  A 27 year old female nurse presented to hematology department with iron toxicity 1 week after self-injecting herself with 20 ampoules of IV iron (4000 mg elemental iron, 60 mg/kg). Her vital signs were stable but she had mild hepatic tenderness.
IS THERE A ROLE FOR MINIMAL RESIDUAL DISEASE MONITORING IN FOLLICULAR LYMPHOMA IN THE CHEMO-IMMUNOTHERAPY ERA?
Authors: Gritti Giuseppe , Pavoni Chiara , Rambaldi Alessandro
Published: December 2016

After 25 years, evaluation of minimal residual disease (MRD) in follicular lymphoma (FL) has become a standardized technique frequently integrated in clinical trials for its consistent and independent prognostic significance. Achievement of a sustained MRD negativity is a marker of treatment sensibility that has been associated with excellent clinical outcome in terms of clinical response and progression-free survival, independently from the employed therapy. However, no survival advantages has been reported for MRD negative patients and despite the compelling results of clinical trials, MRD evaluation has currently no role in clinical practice. Ongoing clinical trials will help in clarifying the potential setting in which MRD monitoring may have a routine clinical application i.e. allowing de-escalation of standard maintenance therapy in very low risk patients. In this review the clinical implications of MRD monitoring in Rituximab-era are discussed in light of the current treatment paradigms most aimed at reducing toxicities, and the response definition that now routinely integrates PET scan. Keywords: Follicular lymphoma, minimal residual disease, molecular remission, outcome prediction
Nonrandomized Trial of Feasibility and Acceptability of Strategies for Promotion of Soapy Water as a Handwashing Agent in Rural Bangladesh

Published: December 2016

We conducted a nonrandomized trial of strategies to promote soapy water for handwashing in rural Bangladesh and measured uptake. We enrolled households with children < 3 years for three progressively intensive study arms: promotion of soapy water (N = 120), soapy water promotion plus handwashing stations (N = 103), and soapy water promotion, stations plus detergent refills (N = 90); we also enrolled control households (N = 72). Our handwashing stations included tap-fitted buckets and soapy water bottles. Community promoters visited households and held community meetings to demonstrate soapy water preparation and promote handwashing at key times. Field workers measured uptake 4 months later. In-depth interviews and focus group discussions assessed factors associated with uptake. More households had soapy water at the handwashing place in progressively intensive arms: 18% (promotion), 60% (promotion plus station), and 71% (promotion, station with refills). Compared with the promotion-only arm, more households that received stations had soapy water at the primary handwashing station (44%, P ≤ 0.001; 71%, P < 0.001 with station plus detergent refill). Qualitative findings highlighted several dimensions that affected use: contextual (shared courtyard), psychosocial (perceived value), and technology dimensions (ease of use, convenience). Soapy water may increase habitual handwashing by addressing barriers of cost and availability of handwashing agents near water sources. Further research should inform optimal strategies to scale-up soapy water as a handwashing agent to study health impact.

Peter Handkes Erzählung Die Morawische Nacht ist eine romanlange „Unterwegserzählung“ eines namenlosen Ex-Autors über sein Leben, seine Wünsche, Träume und Fantasien. Handke erschafft mit der literarischen Figur des Autors ein anderes Ich, welches über seine Verlorenheit der eigenen Seele auktorial erzählt und sich auf die Suche nach seiner eigenen Identität im plurikulturellen Raum des Balkans begibt. Der Ausgangspunkt der Erzählung ist ein fiktiver Ort am Fluss Morawa. Weitere Orte, die im Buch vorkommen, sind: Belgrad, Krk, das kastilische Hochland in Spanien, der Harz in Deutschland, Wien, Gutenstein am Fuße des Semmering, Graz, Triester Karst und schließlich auch Kärnten als der verlorene Heimatort des Autors. Das literarische Meisterwerk eröffnet mit seiner poetischen Sprache und seinem Esprit anhand verschiedener Orte und Kulturen, die in der Erzählung auftreten, einen interkulturellen Dialog.
Metodología de investigación de la retórica intercultural aplicada al ELE
Authors: Heredero Zorzo David
Published: December 2016

La retórica intercultural es una disciplina que estudia el discurso escrito entre individuos procedentes de diferentes culturas. Dentro del mundo científico anglosajón es una corriente muy fuerte, concretamente en lo referente al inglés como segunda lengua, lo que no ocurre en el campo del español como lengua extranjera. La retórica intercultural ha aportado importantes métodos de investigación a la lingüística aplicada, por lo que la aplicación al ELE de esta metodología podría ofrecer perspectivas interesantes. En este trabajo se presenta la metodología de investigación de la retórica intercultural, basada en la utilización de diferentes tipos de corpus para el análisis de géneros y que sigue los preceptos del tertium comparationis, además de servirse de técnicas de investigación etnográficas. Ello se hace con el fin de mostrar las aplicaciones de esta metodología al ELE y esbozar las líneas de investigación abiertas al respecto.
Ključna vloga praktičnega uposabljanja v visokošolskem izobraževanju: kaj prevajalska praksa nudi bodočemu prevajalcu?
Authors: Hirci Nataša
Published: December 2016

V prispevku predstavljamo Prevajalsko prakso Oddelka za prevajalstvo Univerze v Ljubljani, ki je zasnovana praktično in usmerjena ciljno. S prenovo študijskih programov po smernicah bolonjske reforme je na Oddelku za prevajalstvo kot obvezni del magistrskega programa Prevajanje/Tolmačenje predvideno praktično usposabljanje v obliki Prevajalske prakse. Prevajalska praksa je za študente odlična priložnost za vpogled v realno prevajalsko situacijo, delodajalci pa tako lahko spoznajo potencialne bodoče sodelavce. Namen Prevajalske prakse je obogatiti in nadgraditi kakovost študija, omogočiti kasnejšo zaposljivost, ponuditi študentom, da že med študijem spoznajo dobre prakse s področja prevajanja in ponuditi možnosti dela z najsodobnejšimi tehnologijami. Študenti dobijo priložnost, da znanje, pridobljeno na fakulteti, prenesejo v svoje prevajalsko delo in obenem pridobivajo znanja, veščine in izkušnje, ki jim bodo kasneje omogočile učinkovitejšo integracijo v prevajalski sektor. V prispevku podrobneje pregledamo specifične pristope k izvajanju takšne študentske prakse, ki so se v zadnjih desetih letih izoblikovali na Oddelku za prevajalstvo in ponujajo model dobre prakse tudi v širšem okviru praktičnega usposabljanja.
Učinki pomenskega poučevanja španskega člena z vidika kognitivne slovnice: izsledki empirične raziskave

Published: December 2016

Pričujoča raziskava se osredotoča na učinke pomenskega poučevanja španskega člena z vidika kognitivne slovnice z uporabo empirične raziskave. Njen osrednji cilj pa je zagotoviti učečim se operativni model za španski člen in v razumevanje usmerjen model poučevanja. Poleg tega želimo odpreti raziskovalno polje v smeri zagotavljanja spoznavnih orodij, ki bi učečim se v okviru eksplicitnega poučevanja španskega člena pomagala pri tvorjenju pomena v tujem jeziku, za kar se je zdel najprimernejši operativni model za španski člen, vzpostavljen na podlagi teoretskih okvirov kognitivne slovnice (Langacker 2008, Cifuentes Honrubia 1989 in López García 2005). Zato smo naredili operativni model za španski člen, vzpostavljen na podlagi teoretskih okvirov kognitivne slovnice (Ruiz Campillo 1998, Dirven y Radden 2007, Castañeda 2014, Montero 2014b in Santiago 2016) in oblikovali model poučevanja procesiranja, kot ga utemelji Van Patten (1993, 1996, 2002).
Slovenska gostinska ponudba in italijanski gosti
Authors: Gomzi Praprotnik Silva
Published: December 2016

Spoznavanje Slovenije kot turistične destinacije je za italijanskega gosta neizogibno povezano s spoznavanjem gastronomije. Pri pripadnikih naroda, ki tako zavzeto goji kulturo hrane, je gastronomska ponudba v določenem okolju in času v mnogih primerih osnova za celovito dojemanje nekega območja. Dobra ponudba, primerno trženje in dopadljiva predstavitev tipičnih slovenskih jedi imajo pomembno vlogo pri spoznavanju narodne in kulturne dediščine, saj imajo moč širiti nova spoznanja o krajih in ljudeh, odpravljati predsodke in krepiti medkulturno sodelovanje. Prijaznost in strokovna usposobljenost osebja, poznavanje jezika ter civilizacijskih in kulturoloških navad in razlik pa so lahko tisti dejavniki, ki pomagajo uveljavljati lastne izdelke in storitve ter vzgajati in izobraževati uporabnika gostinskih in turističnih storitev.

Prevajanje neologizmov v znanstvenofantastičnih romanih Douglasa Adamsa
Authors: Brezar Nina
Published: December 2016

Namen članka je predstaviti rezultate analize prevajanja neologizmov v znanstvenofantastičnih romanih Douglasa Adamsa, in sicer v seriji romanov Štoparskega vodnika po Galaksiji in v knjigi Losos dvoma. Želeli smo ugotoviti, kako so prevedeni določeni izrazi in katere prevajalske postopke je pri tem uporabil prevajalec. V teoretičnem delu se posvetimo neologizmom in znanstveni fantastiki ter prevajanju le-teh. Obravnavamo tudi prevajalske strategije po Newmarku. V analitičnem delu so predstavljeni izsledki predhodne raziskave: prevodi 57 neologizmov so analizirani na podlagi uporabljenih prevodnih postopkov in ustreznosti v ciljnem jeziku. Izsledki kažejo, da je prevajalec pogosto uporabil domiselni prevod kot funkcijsko ustreznico, medtem ko kulturnih ustreznic skoraj ni uporabljal. Iz analize je tudi razvidna tudi problematičnost prevajanja znanstvene fantastike v slovenščino.

Los paradigmas verbales en papiamento – una herencia africana bien arraigada en un criollo hispánico
Authors: Choghari Maya
Published: December 2016

El papiamento, lengua criolla hablada por aproximadamente unas 200.000 personas a lo largo de las tres islas caribeñas Aruba, Bonaire y Curazao, ha ido ganando desde los principios del siglo XXI el estatus de lengua oficial junto con la lengua holandesa. Encontramos las causas de los orígenes del pidgin en razones históricas y sobre todo gracias a una mezcla única de personas de diferentes orígenes que convivieron en las pequeñas islas donde a lo largo de los años y como lengua de los esclavos dicha lengua se fue desarrollando para convertirse finalmente en una lengua criolla. En general, esta lengua contiene vestigios de la ancestral lengua arahuaco-taíno, influencias africanas así como de las lenguas portuguesa, francesa, inglesa, gallega, y sobre todo de la holandesa y española. La mayor parte del léxico y de la gramática del papiamento deriva de lenguas ibéricas, especialmente del español, así como del holandés, aunque no sucede lo mismo con los paradigmas verbales, la categoría menos influenciada por dichas lenguas. El principal objetivo de este artículo es describir el sistema de conjugación del papiamento, de herencia africana, que se acompaña de ejemplos sacados de cuentos folclóricos sobre la araña sabia Kompa Nanzi.
Generación de mapas de luminancia urbana a partir de un sensor hiperespectral VNIR y una cámara fotogramétrica digital
Authors: Pipia L. , Alamús R. , Tardà A. , Pérez-Aragüés F. , Palà V. , Corbera J. , Arnaldich J.
Published: December 2016

This paper puts forward a methodology for the generation of high resolution luminance maps from simultaneous hyperspectral VNIR and photogrammetric imagery. The integration of hyperspectral radiance at ground level, properly weighted by the photopic-based coefficients, plus a sensor fusion strategy, provides for the first time a quantitative description of the luminous flux at high spatial resolution and with multi-angle geometry. Accordingly, this methodology allows following up any strategic policy aimed to improve urban illumination management and quantifying its effects in terms of energetic efficiency.
Caracterización espectral de Quillaja saponaria (Mol.)
Authors: Acuña T. , Mattar C. , Hernández H. J.
Published: December 2016

This paper presents a spectral reflectance characterization of the specie Quillaja saponaria (Mol.), endemic tree of Chile and valued by society due to its provision of several ecosystem services that gives to society and also for its high concentration of saponins in cortex widely used in the pharmacological industry. For spectral characterization a foliar spectral signatures protocol was designed which included standardized instrumental and environmental parameters. The spectral response of different individuals was measured to evaluate the spectral behaviour and degree of variability within species in the visible and near infrared ranges (VNIR; 400-990 nm) with two hyperspectral sensors (ASD HH and camera PDF-65-V10E). The resulting spectral signatures obtained with ASD HH showed a variation less than 5% of reflectance in VNIR and lesser than that in the transition zone from red to near infrared (red-edge; 680-730 nm). Additionally, two distinctive spectral features were detected for the specie, the first is related to a fast increase of reflectance in bands 450-480 nm and the second, to a marked decrease in the 920-970 nm range associated with water absorption features. At branch level, these distinctive features are maintained but with a smaller magnitude of reflectance, which could indicate that they are useful characteristic spectral patterns that can eventually be used for monitoring the physical health state of the specie using remote sensing. On the other hand, we used a PDF-65 camera for study the plant vigour from different health states (healthy, ill, died) with spectral vegetation index. The Plant Senescence Reflectance Index detected stress on leaves, and Triangular Vegetation Index allows for a gradually characterization of every state. This work provides the first spectral reference for one of the most important sclerophyll species of Chile.
Minimally Invasive Video-assisted Thyroidectomy vs Conventional Open Hemithyroidectomy in Asian Patients
Authors: Singaporewalla Reyaz M , Rao Anil D , Majumder Arunesh
Published: December 2016

Introduction

Although the technique of minimally invasive video assisted thyroidectomy (MIVAT) is well established in continental Europe, data on it's role in Asian patients is limited. We compared the results of MIVAT with conventional open hemithyroidectomy in Asian patients.

Materials and methods

Over a 1-year period, patients undergoing hemithyroidectomy for benign symptomatic goiters were selected. Inclusion criteria for MIVAT were benign colloid goiters, recurrent cysts or follicular lesions and neoplasms with lobe volume of less than 40 cc or nodule diameter less than 35 mm. Larger goiters underwent conventional open surgery. Patients with previous neck surgery and proven malignancy were excluded. Operative time, complications, postoperative pain score, incision length and cosmetic satisfaction at 6 months were recorded.

Results

Thirty-six patients (MIVAT-21, Conventional-15) were included. Both groups were comparable in terms of demographic profile and co-morbidities. The mean operating time for both groups showed no significant difference (MIVAT = 111.67 ± 19.4 min, Conventional = 112.40 ± 25.06 min; p = 0.925). Minimally invasive video assisted thyroidectomy patients had significantly less pain in the immediate postoperative period (mean pain score 2.38 vs 4.8, p < 0.001). Mean incision length at end of surgery was significantly smaller in the MIVAT group (2.58 vs 6.3 cm; p < 0.001). Neck scar satisfaction at 6 months was excellent in 71.4% of MIVAT cases vs 26.6% of conventional hemithyroidectomy cases. There were no complications in any of the treatment groups.

Conclusion

In selected cases, MIVAT is as safe as conventional open surgery with distinct advantages of better postoperative pain control and cosmesis.

Ultrasound-guided Ethanol Ablation: Where does It fit in the Treatment of Recurrent Metastatic Papillary Thyroid Cancer?
Authors: Seiser Natalie , Pasternak Jesse D , Kluijfhout Wouter , Gosnell Jessica E , Shen Wen T
Published: December 2016

Introduction

Ethanol (ETOH) ablation of metastatic neck nodes has been described as a potentially safe and effective alternative to surgical excision. We sought to describe a subset of these patients well suited for ETOH ablation.

Materials and methods

We report ultrasound-guided ETOH ablation of metastatic papillary thyroid cancer (PTC) at a Tertiary Care Endocrine Surgery Unit over 5 years. A retrospective review of all reoperative lymph node dissections was undertaken. Ethanol injection was used as second-line treatment to operative excision and was standardized with ultrasound guidance and the use of 1 cc/cm3 of 100% ETOH solution.

Results

Five treatments of ultrasound-guided ETOH ablation were studied. All patients had been previously treated with radioactive iodine (RAI) (mean: 1.25 treatments of 174mCi), however, in three cases with pretreatment I-131 scan, no uptake of radioiodine was seen in the treated disease. In four cases with pretreatment fludeoxyglucose-positron emission tomography (FDG-PET), treated lesions were avid. Median follow-up time for treatment was 28.5 months, with no disease progression in all ablated lesions. Serum thyroglobulin (Tg) values in patients without Tg-antibody were lower after treatment. There were no complications.

Conclusion

Surgeons seeking a less-invasive approach for nodal metastases in the neck can consider ETOH ablation. Small ultrasound detectable lesions in scarred necks (irradiated and/or reoperative) which are radioiodine non-avid and FDG-PET avid may be best suited for this treatment. As demonstrated by a small set of patients in a Tertiary Care Endocrine Surgery Unit, ETOH ablation is safe and effective at controlling progression of targeted local disease.

Computed tomography (CT) scan revealed a compressive substernal goiter with associated vascular compression, axillosubclavian thrombosis, and saddle pulmonary embolism. Weight-based heparin was immediately administered, and the patient subsequently underwent successful thyroidectomy via a cervical incision. This case report of a rare saddle pulmonary embolism associated with a substernal thyroid goiter underscores the importance of early elective thyroidectomy. Successful management of these potentially devastating pulmonary emboli (PE) associated with large substernal goiters is possible.

Surgical Techniques for operating on Large Adherent Cervical Nodal Metastases from Thyroid Cancer causing Severe Neck Pain and Compression Effects and encasing Major Vessels
Authors: Singh Kul R , Rana Chanchal
Published: December 2016

Aim

We aim to refine and define surgical techniques for doing difficult adherent bulky cervical nodal metastases from thyroid cancer to help surgeons do dissections with better curability and lesser morbidity.

Background

Patients with thyroid cancer with large nodal metastases presenting with severe neck pain due to compression effects and encasing carotid artery and other major vessels pose a challenge to surgeons to do complete resections while preserving important structures in the neck.

Materials and methods

We define surgical planning and road map to dissect difficult bulky adherent cervical nodes encasing carotid artery and jugular vein by splaying the plane over carotid sheath by doing adventitial level dissection and dissecting medial and lateral to carotid sheath the large nodal mass adherent to adjacent structures preserving the major vessels and nerve plexus.

Conclusion

By appropriate surgical planning and meticulous dissection techniques, we can do major neck dissections with complete resections and same time preserving important structures in the neck minimizing morbidity.

Clinical significance: By doing neck dissections with complete oncological resections and saving vital structures in the neck, we aim to offer best possible chance of cure to the patient along with reduced morbidity at same time.

Published: December 2016

Introduction

To verify the influence of age on factors associated with peri-implant bone loss after prosthetic rehabilitation over osseointegrated implants.

Materials and methods

This is an analytical, observational, and longitudinal study with initial 23 participants. Patients presenting with osseointegrated implants with their respective prostheses installed were included, and they could be carriers of chronic and degenerative diseases, such as diabetes, osteoporosis, hypothyroidism, cardiovascular disease (CVD), and systemic arterial hypertension. Thus, 18 participants with 57 implants were selected and followed up from 2009 to 2013. For statistical analysis, chi-square or Fisher's exact test was used for the association of systemic conditions and bone loss. Student's t-test was used for mean comparisons of age and number of total upper and lower implants.

Results

The average age of the sample studied was 71.05 years (65–80). The average implant per person was 3.2. Smoking had an influence on both mesial and distal bone loss, and the latter was significant (p = 0.0370). The association between bone loss and gender was also significant (p < 0.05). Moreover, male gender and upper implants were factors significantly associated with bone loss. The systemic conditions, when isolated, did not have significant influence on implant survival.

Conclusion

Age is not a factor that, alone, contraindicates implant-rehabilitating therapy. On the contrary, smoking has a significant influence on dental implant survival. Systemic diseases, such as osteoporosis, hypothyroidism, diabetes, hypertension, and heart diseases, when controlled, are not contraindication factors.

Clinical significance

This study is relevant for assessing peri-implant bone loss in elderly patients, right after implant installation and over time. Therefore, it was possible to verify that age is not a limiting factor for this procedure. Controlled systemic diseases do not contraindicate implant installation, but smoking is a factor that affects implant survival.

Introduction

The present study was undertaken to evaluate the anatomy of the maxillary sinus in relation to its position and the height of its septa, using cone beam computed tomography (CBCT).

Materials and methods

In this descriptive retrospective study, 300 CBCT images of maxillary sinuses of patients with posterior maxillary edentulism were evaluated. The maxillary sinus septa were evaluated in relation to their prevalence, height, and position; t-test and Mann–Whitney tests were used for the analysis of data.

Results

Sinus septa were detected in 44% of the subjects, with equal frequencies in the anterior, middle, and posterior positions. The mean height of the septa was 3.6 ± 1.56 mm.

Conclusion

In a population of Iranian subjects, in half of the cases, the sinus septa might be present in the anterior, middle, and posterior positions.

Clinical significance

In order to avoid intraoperative problems during sinus lift procedures, it is necessary to accurately evaluate the sinus, preferably with the use of CBCT.

Authors: Qomsan Mohammed AS Abu El , Alasqah Mohammed N , Alqahtani Fahad A , Alobaydaa Mohammed AA , Alharbi Muteb M , Kola Zaheer
Published: December 2016

Introduction

Dental caries and obesity are two of the most prevalent health conditions affecting children. Relative decrease in corporeal movements, escalating inactive lifestyles, and changes in dietary factors are strongly linked with the increasing incidence of overweight and obesity. Furthermore, obesity increases the risk of chronic disease and dental caries that significantly affects the quality of life of young children. The present study intends to explore the relationship between dental caries and obesity in children in Al-Kharj city, Kingdom of Saudi Arabia.

Materials and methods

The present descriptive study was designed as a cross-sectional study in which a total of 386 children in the age range of 6 to 12 years from elementary schools of Al-Kharj city and pediatric dental clinics in Prince Sattam Dental College were included.

Results

Mean decayed filled teeth (DFT) score was found to be considerably higher among obese children. Also, incidence of dental caries in deciduous dentition was found to be notably higher among obese children.

Conclusion

Obesity has a considerable outcome on prevalence of dental caries among primary schoolchildren in Al-Kharj city, Kingdom of Saudi Arabia. The importance of obesity is limited not only to systemic disorders but also in relation to carious lesions. Hence, educating primary schoolchildren about caries and its related factors is very important.

Clinical significance

High intake of free sugar is a wellestablished risk factor for dental caries and also for obesity. Therefore, it is speculated that factors that decrease these risk factors have the potential to affect both conditions at the population level to control it competently.

Effect of Tannic Acid on Bond Strength of Etch and Rinse and Self-etch Adhesive Systems in Dentin of Primary Teeth
Authors: Abdollahi Mojtaba , Ebrahimi Masoumeh , Shirazi Alireza Sarraf , Abdolhoseinpour Faraneh
Published: December 2016

Introduction

One of the possible mechanisms for the gradual destruction of bond strength in dentin-resin interface, could be due to the demineralized unstable collagen matrix. Use of protease inhibitors, such as tannic acid (TA) could prevent destruction of collagen fibers. The aim of this study was to compare the TA effect on bond strength of etch and rinse and self-etch adhesive systems in the dentin of primary teeth.

Materials and methods

This in vitro study was done on 40 extracted primary molar teeth. The teeth were sectioned in the mesiodistal direction, and enamel of buccal and lingual surfaces was removed. Samples were randomly divided into four groups: Single bond (SB) + TA, SB, Clearfil SE Bond (CSB) + TA, and CSB. Then, Z250 and Clearfil AP-X composites were cured on the surfaces of SB and CSB groups respectively. After that, all samples were divided into aging and non-aging groups. For 3 months, samples were placed under 1,000 thermal cycles in aging group. Subsequently, the shear bond strengths of all groups were measured by the International testing machine, and failure mode was evaluated by an optical stereomicroscope. Data were analyzed with paired t-test and independent t-test.

Results

Tannic acid induced a significant reduction in the immediate bond strength of adhesive SB. Meanwhile, TA had no significant effect on shear bond strength of the CSB system.

Conclusion

Based on our findings, use of TA is not recommended with SB and CSB adhesives on primary teeth.

Clinical significance

Tannic acid may not be considered in resin restorations of primary teeth.

Published: December 2016

Introduction

Malocclusions with anterior crossbite are a major esthetic and functional concern for patients. This case report presents a 27-year-old Syrian female who was diagnosed with a class 3 malocclusion, combined with anterior crossbite, deep bite, concave profile, and inadequate maxillary incisor exposure. There was a centric occlusion (CO)/centric relation (CR) discrepancy and the mandible could be manipulated to near edge-to-edge incisal relation.

Correction was done by class 3 intermaxillary elastics on upper and lower mini-implants for the first 6 months, followed by preadjusted edgewise appliance. The objective of implantsupported elastics was to adapt the patient for the CR condylar position without dental effect. Treatment was completed in 24 months with satisfactory dental and facial relationship.

Effect of Complete Denture Rehabilitation on Oral Health-related Quality of Life in Completely Edentulous Patients
Authors: Sethuraman Rajesh , Prajapati Paranjay , Patel Jayanti , Patel Jatan
Published: December 2016

Context

Oral conditions and their impacts on quality of life (QoL) are now important as a tool to evaluate patients’ perception of treatment offered to them. There are various indexes used as a tool to assess the QoL of the individual. The general oral health assessment index (GOHAI) is a proven and reliable index to assess the oral health and its impact on oral healthrelated quality of life (OHRQoL).

Aim

To evaluate the effect of complete denture rehabilitation on OHRQoL in completely edentulous patients.

Settings and design

The study compares the improvement of OHRQoL of 50 completely edentulous patients enrolled in the study, after rehabilitation of them with conventional complete dentures.

Materials and Methods

Hindi version of the GOHAI was used as evaluation tool for OHRQoL.

Statistical analysis

Wilcoxon signed-rank test was applied to assess changes in GOHAI score before and after rehabilitation with a complete denture.

Results

The GOHAI score was seen to be increased from 22.30 ± 1.67 to 27.48 ± 1.13 (p-value < 0.000), which was highly significant.

Conclusion

The GOHAI is an example of a patient-based assessment of oral health problems commonly affecting older adults. The GOHAI assessment indicates improvement in chewing. The highest change between pre- and postinsertion scores was 92.75% for biting or chewing any kind of food.

Comparison of Pain Perception for Nasopalatine Nerve Block using Conventional and Computerized Local Anesthesia Delivery Systems in Adults: A Randomized Split-mouth Clinical Study
Authors: Kohale Bhagyashree R , Agrawal Amit A , Erlewad Dinesh
Published: December 2016

Introduction

Profound local anesthesia (LA) is necessary in order to reduce patient discomfort during oral surgical procedures. However, injection technique itself may be a potentially painful procedure. A comfortable and consistent LA can increase the level of trust between the patient and the operator, since even a thought of intraoral injection causes a considerable amount of anxiety in many patients. To reduce this anxiety, a computer-controlled local anesthesia delivery (CCLAD) system is commercially available as a possible means of minimizing the sensation of pain (especially for palatal injections).

Aim

The aim of the present study was to compare the pain perception, when injections were administered using the CCLAD system or a conventional technique in patients requiring oral surgical procedures in the maxillary anterior region.

Materials and Methods

This randomized split-mouth study included 15 patients (7 females and 8 males). Conventional syringe or computerized single tooth anesthesia (STA) system with a 30-gauge needle was used to give nasopalatine nerve block by the same operator, over a minimum gap of 7 days. Immediately after injection, patient's pain perception was assessed using numeric rating scale (NRS). Overall difference in pain perception and effect of change in sequence of type of anesthesia were determined using unpaired t-test.

Results

Results of the study showed statistically significant difference between the pain scores of STA system and conventional injection technique; however, the change in sequence of anesthesia technique did not show any effect on the effectiveness of STA system.

Conclusion

The STA system significantly reduces the pain perception after administration of nasopalatine nerve block in adults.

Clinical significance

Use of STA system for administration of nasopalatine nerve block in adults provides better patient acceptance and pain control over conventional cartridge syringe.
