Silvia Federici d’hier à aujourd’hui, une théorie pour l’action
Authors: Simonet Maud
Published: January 2023

C’est en tant que « théorie pour l’action » que l’on se propose de présenter ici l’œuvre de Silvia Federici en s’intéressant notamment à la manière singulière dont elle l’a transmise, de multiples façons. On reviendra tout d’abord sur la naissance du mouvement international du « salaire au travail ménager » dans lequel s’est élaborée son approche féministe et sur les mobilisations du collectif new yorkais dans lequel elle l’a mise en pratique. On s’intéressera ensuite au prolongement paradoxal de cette conception subversive du salaire contre le capitalisme, la revendication du «  Wages for  » étant mobilisée aujourd’hui par de nombreux mouvements de « sans salaire », quand Silvia Federici propose une « politique des communs » pour se réapproprier le travail reproductif. En mettant la focale, à partir du travail reproductif, sur cette guerre capitaliste contre les femmes et ses modalités de résistance, c’est à une lecture matérialiste et collective du corps qu’elle nous invite également, parfois au-delà de ses propres positions.
Prendre ses distances avec son identité d’origine : Baudrillard en Amérique, Gombrowicz en Argentine
Authors: Poirier Nicolas
Published: January 2023

Cet article cherche à confronter la démarche de Jean Baudrillard avec celle de Witold Gombrowicz, en particulier le rapport distancié que tous deux entretiennent à leur identité d’origine et le lieu géographique à partir duquel se noue cette relation critique : l’Amérique pour Baudrillard, l’Argentine pour Gombrowicz.
La licence binaire
Authors: Strathern Marilyn
Published: January 2023

Cet article fait usage de la « licence binaire » offerte par le titre du symposium dans lequel il prend place (« Comparative Relativism ») comme une sorte de promesse de connexion. L’auteur suggère que le pouvoir de la bifurcation réside dans le défi de l’hétérogénéité, du caractère fractal de la perspective, du perpectivalisme et des multiplicités : le moment où la divergence crée une relation. Si nous sommes invités – dans le même geste – à considérer des formes de comparaison et des formes de relativisme (en laissant tomber la différence et la similarité), deux autres voies nous sont également offertes, l’une fondée sur un monde de singularités et de multiplicités, et l’autre sur un monde de répétitions pas-tout-à-fait-identiques. L’auteure se demande si le mode binaire n’est pas essentiel au travail épistémique que les chercheurs occidentaux (euro-américains) pourraient vouloir faire, puisqu’ils réinventent sans cesse la division entre le moderne et le post-/pré-moderne. Strathern part du principe que l’anthropologue a le droit de parler des concepts à travers les personnes et commence par interroger la façon dont les Papous Néo-Guinéens qui coexistent dans une ville se comparent entre eux, par opposition aux comparaisons ethniques effectuées ailleurs (par exemple, dans les interactions balkaniques décrites par Sarah Green). En parlant des personnes à travers les concepts, il convient de se demander ce qu’implique la relativisation du travail d’un chercheur à travers celui d’un autre. L’auteur dit que son « intuition » est que dans les deux cas, l’analyste pourrait souhaiter avoir la liberté de discerner – d’un même geste – les multiplicités de ce que John Law et Annemarie Mol appellent le perspectivalisme (leur alternative à la comparaison) et le perspectivisme radicalement divergent d’Eduardo Viveiros de Castro (un relativisme autonome, récursif et surtout socialement spécifique).
Homo alterus . Esquisse d’une anthropologie altérophilique
Authors: Marchal Hervé
Published: January 2023

L’anthropologie de Thomas Hobbes domine les horizons de sens et percole notamment dans le champ les sciences sociales au point de tenir pour vraie et ultime la guerre de tous contre tous. Dès lors, la nature égoïste de l’être humain ne fait plus débat, si bien que s’impose une exclusive anthropologique conduisant à ne voir, parmi les affaires humaines, que domination, concurrence, ruse, pouvoir, violence, avidité, efficacité, rentabilité… La figure d’ homo œconomicus vient renforcer cette prétendue évidence humaine, puisque chacun est censé poursuivre naturellement ses intérêts bien compris et parfaitement clairs, et ce à partir d’un rapport de soi à soi souverain et vu comme indépassable ou primordial. Aux antipodes de cette anthropologie normative mutilante car trop étroite, cet article propose d’identifier quelques traits de ce que pourrait être homo alterus , entendue comme une figure anthropologique à même de penser autrement notre rapport à nous-mêmes, aux autres et au monde.
Le don d’aimer
Authors: Ferrié Christian
Published: January 2023

Le don d’aimer à l’origine du don et du contre-don en est l’élément et le moment d’ordre affectif sans lequel aucune donation ne serait possible. Le don contre don aimant n’est jamais un donnant-donnant équivalent : il n’y a aucune mesure entre ce que la mère donne à l’enfant et ce qu’elle reçoit en retour. Aimer est en ce sens toujours un don et jamais un dû, de sorte que le devoir d’aimer s’avère indu : ce qui vaut plus encore de l’exigence d’une prestation sexuelle au nom du devoir conjugal. La transmutation du don en dû provoque une dégénérescence de la générosité fourvoyée en dévouement sacrificiel. Même si la gratitude est bien due en réponse au don reçu, l’obligation morale et sociale de rendre exige un supplément d’âme pour être convertie en contre-don généreux grâce au don d’aimer.
Moscou, Washington et le Saint-Siége au début du pontificat de Jean-Paul II
Authors: Gayte-Lebrun Marie
Published: January 2023

L’élection de Karol Wojtyla en octobre 1978, en plein regain de tensions dans la guerre froide, ne laisse indifférents ni Moscou ni Washington. Le premier redoute des critiques de son traitement des croyants, susceptibles de nuire à son utilisation de forums religieux internationaux pour légitimer sa politique étrangère ; il craint également une poussée du nationalisme dans les républiques à forte présence catholique. Le deuxième se réjouit de l’avènement d’un pontife à première vue en phase avec ses priorités, Moscou ne manquant d’ailleurs pas une occasion de souligner l’inféodation du pape aux États-Unis. L’étude des archives montre cependant que malgré la méfiance de Jean-Paul II envers les Soviétiques, les États-Unis ne peuvent pas toujours compter sur celui qu’ils pensaient être un « allié » dans leur « croisade » anticommuniste, et que Jean-Paul II doit composer entre les aspirations à la « supériorité morale » de Washington et son désir ardent de désarmement.
Breast Reduction Surgery in Adolescents
Authors: Patel Krishnabhai , Corcoran Julia
Published: January 2023

Macromastia—overgrowth of the female breast—is distressing and disabling, often starting in middle school and continuing into adulthood. Breast reduction is an effective treatment of symptoms of macromastia in adults, and its application in adolescents has been increasing. Special considerations within the adolescent population include interruption of age-appropriate activities, development of healthy body image/esteem, the connection to obesity, potential for postoperative recurrence/continued growth, the effect of surgery on future lactation and breast-feeding, and the adolescent's ability to participate in surgical decision-making (assent). This review highlights these issues and reviews breast reduction surgery outcomes and complications as they apply to the female adolescent. After reading this article, the reader should be able to identify adolescents who may be candidates for breast reduction surgery and have the information needed to counsel patients before their referral to a surgeon.

Authors: Mishra Kapil , Velez Gabriel , Chemudupati Teja , Tang Peter H. , Mruthyunjaya Prithvi , Sanislo Steven R. , Mahajan Vinit B.
Published: January 2023

Objective:

To study the incidence of intraoperative complications while collecting a vitreous sample for proteomic biomarker analyses during small-gauge pars plana vitrectomy (PPV).

Methods:

A retrospective case series was assembled from the surgical logs and charts of patients who underwent 23-, 25-, and 27-gauge PPV along with an undiluted vitreous biopsy. Primary surgical indication and detailed operative reports were reviewed. Complications specific to vitreous biopsy were assessed while complications related to vitrectomy in general without biopsy were not tabulated.

Results:

In 1190 eyes that underwent vitreous biopsy, the most common indications for PPV were rhegmatogenous retinal detachment (24.2%), epiretinal membrane (ERM) (21.7%), vitreous hemorrhage (11.0%), uveitis (8.3%), and macular hole (7.5%). An adequate sample of 0.5 cc to 1.0 cc was obtained in all cases. There was one sclerotomy break associated with biopsy, but no instances of lens touch, retinal contusion, retinal detachment, or intraocular hemorrhage.

Conclusions:

Undiluted vitreous biopsy obtained at the time of small-gauge vitrectomy is a generally safe procedure and may be considered for collection of samples for proteomic analysis.

Published: January 2023

Background:

To identify vitreoretinal practice patterns in the months following the initial 2020 national shutdown due to the COVID-19 pandemic in the United States (US).

Study Design:

Retrospective analysis of vitreoretinal practice patterns from multiple retinal centers across the US from January 1, 2018 to December 31, 2020.

Results:

The lowest utilization of retina care occurred during the week of March 23, 2020, after which utilization returned to pre-pandemic levels by July 2020. Patients with retinal detachments (RDs) presented with worse visual acuity during March, April, and May 2020 compared to the same time periods of 2018 and 2019 (
P
values < 0.05). However, only comparing eyes that presented in March 2018 to March 2020, was the year 1 vision significantly worse (
P
= 0.008).

Conclusion:

The COVID-19 pandemic significantly impacted vitreoretinal care. The vision of patients with RDs may not have been affected by the delayed presentation.

An adaptive finite element method based on Superconvergent Cluster Recovery for the Cahn-Hilliard equation
Authors: Tian Wenyan , Chen Yaoyao , Meng Zhaoxia , Jia Hongen
Published: January 2023

In this study, we construct an error estimate for a fully discrete finite element scheme that satisfies the criteria of unconditional energy stability, as suggested in [1]. Our theoretical findings, in more detail, demonstrate that this system has second-order accuracy in both space and time. Additionally, we offer a powerful space and time adaptable approach for solving the Cahn-Hilliard problem numerically based on the posterior error estimation. The major goal of this technique is to successfully lower the calculated cost by controlling the mesh size using a Superconvergent Cluster Recovery (SCR) approach in accordance with the error estimation. To demonstrate the effectiveness and stability of the suggested SCR-based algorithm, numerical results are provided.
Point cloud registration: a mini-review of current state, challenging issues and future directions
Authors: Brightman Nathan , Fan Lei , Zhao Yang
Published: January 2023

A point cloud is a set of data points in space. Point cloud registration is the process of aligning two or more 3D point clouds collected from different locations of the same scene. Registration enables point cloud data to be transformed into a common coordinate system, forming an integrated dataset representing the scene surveyed. In addition to those reliant on targets being placed in the scene before data capture, there are various registration methods available that are based on using only the point cloud data captured. Until recently, cloud-to-cloud registration methods have generally been centered upon the use of a coarse-to-fine optimization strategy. The challenges and limitations inherent in this process have shaped the development of point cloud registration and the associated software tools over the past three decades. Based on the success of deep learning methods applied to imagery data, attempts at applying these approaches to point cloud datasets have received much attention. This study reviews and comments on more recent developments in point cloud registration without using any targets and explores remaining issues, based on which recommendations on potential future studies in this topic are made.
A New Resource Recommendation Method for Experiential Leaching Based on the Completion Degree of Online Learning Tasks
Authors: Jia Ligang
Published: January 2023

Experiential Learning (ExL) is an effective way to consolidate theoretical knowledge and deepen understandings, and the recommendation of ExL resources needs to also take the effect of students’ theoretical learning into consideration. However, existing studies generally ignore the stage-by-stage assessment of students’ completion of online learning tasks, and the recommendation performance of existing resource recommendation models for ExL is not satisfactory enough. Therefore, the recommendation method needs to be innovated, and the interpretability of recommendation results is facing challenges. To respond to these issues, this paper studied a new resource recommendation method for ExL based on the completion degree of online learning tasks. At first, the paper gave the principle of recommending ExL resources based on the completion degree of online learning tasks, and built an online learning task completion degree prediction model. Then, this paper adopted a bi-directional GRU network model based on attention mechanism to analyze the recent online learning behavior sequence of students and attain the completion degree of students’ short term learning tasks. After that, a knowledge map representing ExL resources and the correlation of knowledge attributes was drawn; by combining the completion degree of both the short-term and long-term learning tasks, the ExL resources suitable for students were recommended to them. At last, experimental results verified the effectiveness of the constructed model.

Published: January 2023

The innovations brought by the digital age leave deep traces in the lives of individuals of all ages. With technological tools becoming an integral part of life, we are observing changes in the behaviors and reactions of individuals. Mobile technology pushes individuals to ease and drags them to loneliness in society. Individuals who withdraw into their shells are socializing on mobile platforms. The progress of science and technology from past to present has brought changes in society. Rapidly advancing technology shapes the lives of individuals in many areas. Digitalization has been efficient in the exposure of individuals to an insidious application of mobbing. In this context, the mobile world has come to the point that it threatens the living space of the individual with the content that is a design product it offers. In particular, the role of digital media in a way that interferes with every aspect of life has turned into digital despotism. In this study, which is considered a compilation, we used document analysis as a data collection tool. We obtained data by examining the documents related to the subject and handled it through descriptive analysis. In this context, while trying to examine the concept of "mobile mobbing", the other side of the digital world; we discussed digitalization, mobbing, digital violence, cyberbullying, digitalization, and its aspects on human life. As a result, we have reached a high relationship between mobile mobbing and its effect on individuals. Among these results, there are changes in their behaviors and habits, the digital world has turned into a covert mobbing tool, social media contents influence the attitudes of users through hidden messages, exerts pressure on their behavior by directing them, disturbing insults and threats, etc. are shared in communication styles, we have concluded that mobbing is experienced in a similar digital environment. In this context, we have listed suggestions and measures against mobile mobbing, with digital media users being more careful and conscious of techniques, respecting safe sharing with courtesy rules in their discourse and actions.
Possible Translation Problems, Their Causes, and Solutions in Agile Localization of Software
Authors: Kabát Marián
Published: January 2023

This paper presents some initial insights into practical translation problems that can occur during agile localization. Although agile localization is not a novel approach to software localization, the range of possible translation problems and their causes and solutions have not yet been described.

In order to write this paper, an ad hoc monolingual English corpus made up of user interface strings of one agile localized software product was used. The corpus was analyzed string by string, and various causes of translation problems, mostly relating to lacking context, were identified. The paper presents and discusses sample cases of these problems.

This paper tries to show that while agile localization can be used as an alternative to traditional localization, the development team must be open to cooperation with the localization team in order for agile localization to be successfully implemented; otherwise, problems will occur.

La tolérance administrative au Cameroun : odyssée au confluent de la norme juridique et de l’anorme
Authors: Mangmadi Ebenezer David Ngahna
Published: January 2023

Dans l’imagerie populaire, le pouvoir d’État, dans son pendant politico-administratif notamment, évoque habituellement la figure effrayante du monstre froid de Nietzsche. Il représenterait quelque chose de terrifiant et d’inexorablement répressif. Cette vue des choses ne correspond pourtant pas toujours à la réalité. Il est en effet des situations, bien nombreuses, dans lesquelles, le rouleau compresseur ne se déploie pas. L’hypothèse de la tolérance administrative prend alors tout son sens. Au Cameroun, on est tout de suite frappé par l’ampleur de ce phénomène qui a considérablement gagné en importance ces dernières années. Entre échoppes aménagées illégalement sur la voie publique, et congrégations religieuses qui fonctionnent sans autorisations préalables, les signes de la tolérance administrative sont perceptibles dans toutes les sphères de la société. Si en toute logique on est porté à interroger la démarche, c’est en réalité la question de son sens profond qui est excipée. À date, pourrait-on se demander, comment appréhender la tolérance administrative au Cameroun ? L’opinion émise dans le cadre de ce propos est que prise en contexte, elle s’analyse comme un procédé politique de l’action administrative.tolérance administrative, action administrative, procédé politique, sécurité juridique
IMPACTO DE LOS CRITERIOS DE CALIDAD DEL AMBIENTE INTERIOR EN LA CERTIFICACIÓN DE EDIFICIOS DE OFICINAS SUSTENTABLES EN CHILE
Authors: Trebilcock-Kelly Maureen , Chávez-Finol Fernando
Published: January 2023

Los sistemas de certificación de sustentabilidad en las edificaciones se centran en la dimensión ambiental através de criterios orientados al ahorro de energía y la disminución de gases efecto invernadero. Sin embargo, en la actualidad existe una preocupación creciente por la sustentabilidad social centrada en el bienestar y salud de los ocupantes, a través de criterios de Calidad del Ambiente Interior (CAI). Este artículo se basa en el análisis comparativo del sistema de certificación chileno CES y el internacional LEED, evaluando el impacto de los criterios de CAI tanto en el diseño de los sistemas, como en una muestra de edificios de oficinas certificados en Chile. Los resultados indican que CES otorga mayor relevancia a la dimensión CAI que LEED. Dentro de las subcategorías, ambos sistemas priorizan los criterios de calidad del aire por sobre confort térmico y visual. La base de datos de edificios certificados en Chile indica que los criterios más utilizados por LEED se centran en la calidad del aire a través de estrategias de materiales de bajas emisiones y gestión de la construcción, mientras que los edificios certificados CES priorizan estrategias de diseño que abordan aspectos térmicos, lumínicos, acústicos y de calidad del aire.
HMDS PARA REALIDADE AUMENTADA EM AECO:
Authors: Skubs Danielle , Cuperschmid Ana Regina Mizrahy
Published: January 2023

Experiências de Realidade Aumentada (RA), através de Head Mounted Displays (HMDs), para a área de Arquitetura, Engenharia, Construção e Operação (AECO), já são uma realidade, ainda que pouco explorada frente a outras áreas. Os HMDs apresentam uma opção valorosa para RA, visto que oferecem maior consistência pictórica e sensação de presença. Dada a constante atualização tecnológica, a apresentação de uma relação dos HMDs disponíveis comercialmente se tornaria rapidamente obsoleta. Por este motivo, busca-se descrever as características fundamentais que devem ser observadas para a seleção de HMDs de forma a atender demandas específicas de atividades na área de AECO. De forma a apresentar uma categorização, as especificações técnicas dos HMDs foram segmentadas segundo: portabilidade, visualização, sistemas de rastreamento e posicionamento, resistência ao intemperismo e ambientes agressivos, mecanismos de interação, hardware e software. Essas características foram fundamentadas por referências bibliográficas para, posteriormente, serem correlacionadas com atividades comumente desenvolvidas no setor. Essa pesquisa contribui para a escolha consciente e criteriosa de HMDs, favorecendo a incorporação de experiências de RA em atividades de AECO.

Este artigo promove uma revisão sobre distintas abordagens, nos âmbitos da arquitetura, do projeto urbano e do planejamento, à infraestrutura rodoviária, reconhecida como oportunidade para um entendimento projetual em diálogo com as paisagens e formas que marcam a urbanização contemporânea. Para além de parâmetros ou instrumentos excessivamente normativos e idealizações de cidades compactas, discutem-se potencialidades extraídas de um referencial propositivo. Recorre-se, assim, a uma pesquisa de obras, paradigmas e práticas levadas a cabo, testadas e construídas em diferentes cidades, contrapondo suas virtudes e qualidades. Aponta-se, por fim, para a necessidade de uma revisão conceitual, a emergir da descrição de espaços e formas que, tanto em escala ampliada quanto à escala local, se marcam pela excessiva especialização, mas que, para o bem ou para o mal, atuam como vetores inexoráveis do crescimento urbano.

Este estudo aborda a trajetória de Luiz Alexandre de Oliveira, um estudante negro, pobre e deficiente visual que alcançou projeção social como professor, diretor e proprietário de instituições educativas em Campo Grande, no então sul de Mato Grosso. Além disso, as memórias do professor destacam suas relações com a comunidade e com a escola japonesa no período varguista (1937-1945). As análises decorrem do cruzamento de fontes memorialísticas e documentais, sob a ótica dos estudos de Pierre Bourdieu. O acesso ao ensino secundário proporcionou-lhe a inserção em outros campos sociais, bem como permitiu que se tornasse uma referência de prestígio da cidade, sendo reconhecido como benfeitor pela comunidade japonesa ao resguardar os bens e proteger a escola japonesa.
Recolhidas, Mestras e Educandas
Authors: Lage Ana Cristina Pereira
Published: January 2023

O artigo trata da história dos recolhimentos criados no período moderno com a intencionalidade de guardar, moldar e/ou punir mulheres. No caso da América Portuguesa, os recolhimentos, tanto supriram a falta dos modelos conventuais, quanto guardaram ou puniram as mulheres habitantes desse território. A partir da segunda metade do século XVIII, em função da circulação das ideias iluministas, surgiram alguns educandários anexos àqueles espaços, com a finalidade de educar as mulheres para a vida secular e prepará-las para o matrimônio e a maternidade. Os Estatutos do Recolhimento Nossa Senhora da Glória do Recife, obra publicada em 1798, pelo bispo Dom Azeredo Coutinho, retratam a intenção educativa e a capacidade de reformulação e de adaptação dos Recolhimentos.

Published: January 2023

In this research, FexOy/C was first prepared through one-step pyrolysis of FeCl3-coffee husk mixture. The surface of FexOy/C was then loaded with Ag particles using an ex-situ method, producing Ag-FexOy/C. XRD result indicates that different crystals of Fe3O4, Fe2O3, and FeO(OH) were formed on the surface of porous carbon. The existence of 0.41 wt% Ag and 3.13 wt% Fe was determined by AAS results. Subsequently, Ag-FexOy/C was primarily explored for its antibacterial and catalytic applications. According to the ASTM E2149-13a standard, the material killed 62% of Staphylococcus aureus within 60 min of contamination. For catalytic performance, 50 ppm sunset yellow FCF was decolorized by 240 ppm H2O2 using 0.40 g/L Ag-FexOy/C at pH 3.0. The results showed that Ag-FexOy/C had an adsorption capacity of 7.8 mg/g and an average decolorization rate of 41.6 mg.g-1.h-1. This rate was approximately 13-fold higher than that without a catalyst. Furthermore, Ag-FexOy/C with a saturation magnetization of 3.62 emu/g was separated and recovered easily from the treated mixture by a magnet bar. Overall, the findings initially prove that Ag-FexOy/C is a promisingly multifunctional material, thanks to its antibacterial activity, adsorption capacity, catalytic activity and magnetic recoverability.
Evaluation of Infraorbital Nerve Recovery and its Effect on Quality of Life following Open Reduction and Internal Fixation of Zygomaticomaxillary Complex Fractures – An Evaluative Study
Authors: Dhabaria Husain , Kolari Vinayakrishna , Sequeira Joyce , Shah Abhishek
Published: January 2023

Introduction:

The zygomaticomaxillary complex (ZMC) fractures are the second most common fractures affecting the midfacial skeleton. Neurosensory disturbances of the infraorbital nerve are one of the most common signs of ZMC fractures. The aim of the study was to evaluate the neurosensory recovery of the infraorbital nerve and its effect on the quality of life (QoL) following open reduction and internal fixation of ZMC fractures.

Methods:

Thirteen patients clinically and radiologically diagnosed with unilateral ZMC fractures with neurosensory deficits of the infraorbital nerve were enrolled for this study. All patients were assessed presurgically for neurosensory deficits of the infraorbital nerve using the various neurosensory tests, followed by open reduction with two-point fixation under general anaesthesia. The patients were followed up at one, three and six months postoperatively to evaluate the recovery of neurosensory deficits.

Results:

Recovery of tactile and pain sensation was relatively complete in 84.62% and 76.92% of patients respectively by the end of six months postoperatively. The spatial mechanoreception of the affected side improved significantly. 61.54% of patients led an excellent QoL six months postoperatively.

Discussion:

The majority of the patients with ZMC fractures and neurosensory deficits of the infraorbital nerve, when treated with open reduction and internal fixation, have complete recovery of the neurosensory deficits by the end of six months postoperatively. However, some patients may continue to experience some long-term residual deficits, which can affect the patient’s QoL.
A Radiographic Study on Pterygoid Implants with Hamulus as a Landmark for Engaging the Pterygoid Plate - A Retrospective Study
Authors: Motiwala Irfan Ali , Bathina Tejaswi
Published: January 2023

Introduction:

Rehabilitating the posterior maxilla with pterygoid implants can be quite challenging as the area entails many hindrances for implant placement. Although few studies have reported the three-dimensional angulations according to various planes (Frankfort horizontal (FH), sagittal plane, occlusal or maxillary planes), no anatomical landmarks have been identified to guide their placement. This study aimed at analysing the three-dimensional angulation of pterygoid implants using the hamulus as an intraoral guide.

Methods:

Pre-operative cone-beam computed tomography scans (axial and parasagittal sections) of 150 patients rehabilitated with pterygoid implants were retrospectively analysed to determine the horizontal and vertical angulations in relation to the hamular line and FH plane, respectively.

Results:

The results showed horizontal buccal and palatal safe angulations of 20.8° ± 7.6° and −20.7° ± 8.5° in relation to the hamular line. Maximum and minimum vertical angulations of 61.6° ± 7.0° and 37.2° ± 10.3° were observed, with a mean of 49.8 ± 8.1 in relation to FH plane. The post-operative scans showed that around 98% of the implants placed along the hamular line were successfully engaging the pterygoid plate.

Discussion:

Comparing with the results of previous studies, this study concludes that when implants are placed along the hamular line, they are more likely to engage the centre of the pterygomaxillary junction resulting in an excellent prognosis of pterygoid implants.
Effect of Local Anaesthesia with and without Adrenaline on Blood Glucose Concentration in Patients Undergoing Tooth Extractions - A Comparative Study
Authors: Nair Vivek Sunil , Anusuya N , Sankar K. , Sathiyanathan D. , Sane Vikrant Dilip , Kanagasabapathy Thirumurugan
Published: January 2023

Introduction:

Local anaesthesia (LA) is the usual drug used in dentistry to reduce intraoperative pain. The efficacy of lignocaine is improved by adding adrenaline as a vasoconstrictor. Adrenaline decreases the systemic absorption of LA and reduces blood loss during the surgical procedure. The study was conducted to observe the effect of adrenaline on blood glucose concentration in patients undergoing tooth extraction.

Materials and Methods:

The study was conducted on 100 patients needing multiple teeth extraction. On the first appointment, extraction was done using lignocaine without adrenaline (plain), and for the second appointment, extraction was done using lignocaine with adrenaline (1:200,000). Serial blood glucose estimations were carried out at identical intervals on both occasions.

Results:

Significant difference in blood glucose level was noted when the patients received lignocaine with adrenaline before administration and after 10 min/20 min intervals (P < 0.05).

Discussion:

Constant vigilance and prudence are recommended while using lignocaine with adrenaline in patients suffering from diabetes mellitus.

Clinical studies where Clonidine + lignocaine and Adrenaline + lignocaine were compared directly during nerve block administration exclusively for third molar surgical removal were selected.

Participants, Study Appraisal:

This current systematic review is registered in Prospero database CRD42021279446. Two independent reviewers were involved in collection, segregation and analysis of electronic data. The data were compiled in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Search was conducted till June 2021.

Synthesis Methods:

Qualitative analysis of the selected articles was performed for systematic review. Meta-analysis is performed using RevMan 5 Software. Heterogeneity through the I2 statistics. Change in the haemodynamic parameters was the primary outcome evaluated, and secondary outcomes evaluated were onset and duration of anaesthesia in both the groups.

Results:

In all databases, 1141 records were screened, out of which a total of 21 articles were included for the evaluation for full-text analysis. Out of these, 16 articles were excluded and 5 articles were included for the final systematic review. Meta-analysis was performed only for 4 studies.

Conclusion:

Amongst the evaluated haemodynamic parameters, there was a significant reduction in the heart rate (baseline to intraoperative period) in clonidine and lignocaine groups than in adrenaline and lignocaine groups during nerve block administration for third molar surgical removal. There was no significant difference between other primary and secondary outcomes evaluated.

Limitations:

Blinding was not performed in all the studies, randomisation was performed in only three studies. The volume of local anaesthesia deposited varied in the studies (2 mL in three studies and 2.5 mL in two studies). Most of the studies (n = 4) were evaluated on normal adults and only one study evaluated mild hypertensive patients.

Published: January 2023

Introduction:

Maxillofacial trauma accounts for a high percentage of patients reporting to the emergency medicine department and being admitted in the hospital. The purpose of this study was to form a direct association between maxillofacial fractures and traumatic brain injury (TBI).

Methods:

Ninety patients with maxillofacial fractures that reported to/were referred to the Department of Oral and Maxillofacial Surgery were observed for features indicative of TBI based on clinical presentation and radiological interpretations. Parameters such as loss of consciousness, vomiting, dizziness, headache, seizures and the requirement for intubation, cerebrospinal fluid rhinorrhoea and otorrhoea were also assessed. Appropriate radiographs for the diagnosis of the fracture were taken followed by a computed tomography (CT) scan when indicated in accordance to the Canadian CT Head Rule. These scans were then assessed for contusion, extradural haemorrhage, subdural haemorrhage, subarachnoid haemorrhage, pneumocephalus and cranial bone fracture.

Results:

A total of 90 patients were evaluated, of which 91.1% were males and 8.9% were females. Association between the occurrence of head injury and different maxillofacial bone fractures using the Chi-square test showed a statistical significance of <0.001 in patients with naso-orbito-ethmoid as well as frontal bone fractures. There was a clear association between fractures present in the upper as well as the middle third of the face and traumatic head injury (P ≤ 0.001).

Discussion:

Patients with the frontal bone and zygomatic bone fractures have a high prevalence of TBI. Patients with the upper and middle third of the face injury are more prone to traumatic head injury and importance should be given to patients with the same and prevent poor prognosis.

Authors: Kakati Kaberi , Maibam Puspakishore Singh , Ingtipi Dimi , Das Ashok Kumar
Published: January 2023

Introduction:

Nutrition plays a significant role in the life of every individual and helps in recovering from any injury including surgery. Pre-treatment malnutrition is found in 15%–40% of cases and can influence treatment outcome. The study aims to determine the impact of nutritional status on the post-operative outcome after head and neck cancer surgery.

Materials and Methods:

This study was carried out in the Department of Head and Neck Surgery for a period of one year from May 1, 2020 to April 30, 2021. Only surgical cases were taken up for the study. The cases (Group A) had a thorough nutritional assessment and dietary intervention if necessary. The dietician did the assessment via Subjective Global Assessment (SGA) questionnaire. After the evaluation, they were again subdivided into two subgroups depending on their nutritional status – well nourished (SGA-A) and malnourished (SGA-B and C). Dietary counselling was given for minimum 15 days preoperatively. The cases were compared with a matched control group (Group B).

Results:

Both the groups were well matched in terms of the site of primary tumour and duration of surgery. Around 70% were found to be malnourished in Group A. With dietary counselling, there has been a significant improvement in various parameters of post-operative outcome (P < 0.05).

Discussion:

This study highlights the close association and the importance of nutritional assessment for all head and neck cancer cases planned for surgery for an uneventful post-operative outcome. Adequate nutritional assessment and dietary intervention in the pre-operative period can go a long way in reducing post-operative morbidity in surgical patients.

Authors: Petronis Zygimantas , Spaicyte Nerija , Sakalys Dovydas , Januzis Gintaras
Published: January 2023

Background:

The objective of this study was to evaluate the efficiency of functional rehabilitation in terms of mouth opening, quality of life, healing process, occlusion and dysfunction, between different treatment methods, after condylar fractures, based on the current literature.

Methods:

Using the PRISMA guidelines in search of clinical trials published between 2011 and 2021, a literature analysis was performed. This search was conducted using the following Medical Subject Headings (MeSH) terms: rehabilitation OR mouth opening recovery OR function recovery AND mandibular fracture OR condylar fracture.

Results:

The literature search resulted in a total of 110 study articles, of which seven publications were used in the present review, according to a selection based on the pre-established eligibility criteria. The review showed that open reduction resulted in a better three-dimensional recovery of mandibular movements and revealed greater results regarding the absence of the symptoms after applied treatment. However, studies assessing closed reduction, especially performed with intermaxillary fixation screws (IMFS), revealed excellent results in terms of quality of life, mouth opening and occlusal parameters.

Discussion:

This systematic literature review showed that open reduction resulted in a better three-dimensional recovery of mandibular movements and showed greater results regarding the absence of symptoms. However, studies assessing CR, especially those performed with IMFS, revealed excellent results in terms of quality of life, mouth opening and occlusal parameters.
Gender-based predilection for the microbial load of Aggregatibacter actinomycetemcomitans present in anterior versus posterior implant sites
Authors: Sengupta Soumee , Ganesh S. , Meenakshi S. , Rao Raghavendra M. , Swamy K. N. Raghavendra
Published: January 2023

Purpose of Study:

Bacterial biofilm-induced peri-implantitis has been one of the leading causes of implant failure. There are a plethora of local and systemic factors that have been studied at a depth and thereafter have been proven to have a contributory role in the overall disease progression. Epidemiological factors such as site specificity and gender stand to be two confounding factors that have insufficiency in the literature regarding their involvement in the same. Thus, the present article aims to address this gap in the literature and present conclusive evidence about the gender-based comparative evaluation of the microbial load of Aggregatibacter actinomycetemcomitans, one of the potential periodontopathogens for the disease progression, present in anterior versus posterior implant sites.

Materials and Methods:

Twelve patients (six males and six females) undergoing the implant prosthetic rehabilitation at two intraoral sites, one anterior and one posterior region, were selected as suitable subjects and the healing abutments as the clinical test samples. Culture-independent microbiological analysis was carried out for all the samples for quantification of A. actinomycetemcomitans.

Results:

The mean viable bacterial DNA count was 503076.49 copies/μL for the male subjects and 474587.85 copies/μL for the female subjects. Hence, there was no significant function correlating gender specificity and the viable bacterial DNA counts. The mean total of viable bacterial DNA counts for the anterior region (site 1) was 407087.17 copies/μL and for the posterior region (site 2) was 570577.17 copies/μL, irrespective of the gender. Thus, a highly significant difference was observed in the mean viable bacterial DNA counts between site 1 and site 2 (F = 20.214; P = 0.001) irrespective of the gender.

Conclusion:

There seems to be no gender-based predilection for the quantification of viable bacterial DNA counts for A. actinomycetemcomitans. However, a propensity for the presence of higher bacterial load of A. actinomycetemcomitans, one of the causative microorganisms of per-implant diseases, does exist for the implants placed in the posterior region as compared to those placed in the anterior region.

Published: January 2023

Aim:

The goal of this study is to discuss the commissioning and dosimetric parameters achieved during the clinical implementation of an indigenously developed intracavitary (IC) plus interstitial (IS) template for high dose rate (HDR) image-guided brachytherapy (IGBT) in cancer (Ca) cervix. We want to discuss our achieved values of cumulative equi-effective doses (EQD2) for high-risk clinical target volume (HRCTV) and organ at risk (OAR) and compare it with available published results.

Materials and Methods:

Medanta anterior oblique/lateral oblique template has a total of 19 needles including the central tandem. For commissioning the template with needles, the indigenously made acrylic phantom was used. Oblique and straight needles were placed inside the acrylic phantom and a computed tomography (CT) scan was performed. Sixteen patients were treated in HDR IGBT using this template after external-beam radiotherapy. The IGBT plans were evaluated based on EQD2 of target coverage i.e., dose received by 98% (D98%_HRCTV), 90% (D90%_HRCTV), and 50% (D50%_HRCTV) volume of HRCTV, and dose received by 2 cc (D2cc) and 0.1 cc (D0.1cc) of OAR using linear quadratic (LQ) radiobiological model.

Results:

The autoradiographic in radiochromic film shows that the distance between the needle tip and the middle of the source position is 6 mm. The mean D98%_HRCTV and D90%_HRCTV was 76.8 Gy (range: 70-87.7 Gy, P < 0.01) and 84.49 Gy (range: 76.6-96.7 Gy, P < 0.01), respectively. Mean EQD2 of D2cc of the bladder, rectum, and sigmoid was 85.6 Gy (range: 77.5-99.6 Gy, P < 0.03), 74.3 Gy (range: 70.9-76.7 Gy, P < 0.05), and 58.3 Gy (range: 50.6-67.9 Gy, P = 0.01), respectively. The mean total reference air kerma at a 1 m distance is 0.489cGy (range: 0.391-0.681cGy).

Conclusions:

The indigenously developed template could attain satisfactory standards in terms of set parameters for commissioning and acceptable dose volume relations in our clinical use for treating the advanced Ca cervix patients who need IC + IS type of HDR IGBT. The comparative analysis with contemporary applicators was acceptable.
