O schwannoma vestibular (SV) é um tumor benigno que se origina das células de Schwann e acomete o nervo vestibulococlear. É o tumor mais comum da bainha nervosa, representando cerca de 80% dos tumores que acometem o ângulo pontocerebelar (APC) do VIII nervo craniano. Apresenta baixa incidência na população mundial, ocorre mais em mulheres e está mais presente entre os 50 a 60 anos de vida. A metodologia se baseia em uma revisão de literatura, qualitativa e descritiva, foram utilizados artigos em português, inglês e espanhol da plataforma científica Portal Regional da Biblioteca Virtual em Saúde (BVS), Medline, Lilacs, Pubmed e Scielo. A pesquisa identificou diversas manifestações clínicas diante do tumor, sendo a hipoacusia o sintoma mais comum, além do zumbido, vertigem ou tontura, cefaleia e dormência facial. O neuroma acústico, atualmente apresenta várias opções de tratamento, que varia desde uma conduta expectante a um manejo cirúrgico. Assim, a intervenção cirúrgica representa a forma de tratamento mais empregada, com melhores resultados, além de poder se associar a outras condutas, sempre analisando as características clínicas do paciente e o tamanho do tumor.

Efraín Huerta y Pablo Neruda: poesía y política antifascista en el diario El Popular (1939-1944)
Authors: Quintana Sergio Ugalde 
Published: October 2024

Este ensayo analiza, a partir de las colaboraciones de Efraín Huerta y de Pablo Neruda en el periódico obrero El Popular, los proyectos poético-políticos que una red de escritores articuló en México, bajo el horizonte del discurso del antifascismo, durante el desarrollo de la Segunda Guerra mundial. Los proyectos literarios difundidos y promovidos en este periódico, fundado por Vicente Lombardo Toledano, conformaron un laboratorio estético en el que se conjugaron de forma abierta una crítica a la violencia fascista y el deseo de un futuro mejor. Este deseo crítico y utópico muestra una especial relación entre literatura y política a inicios de los años cuarenta en México.

Authors: Chabaya Blessing , Govender Cookie M. , Kanengoni Herbert 
Published: October 2024

Orientation: The study was conducted in two higher education institutions that underwent insourcing and harmonisation of conditions of employment for support services.Research purpose: This study aims to determine how harmonisation shapes outcomes among support service labour in selected higher education institutions and to develop a management framework to harmonise conditions of employment following insourcing.Motivation for the study: The study capitalises on organisational complexities in higher education institutions that experienced insourcing of support services employees to address concerns assumed to be premised on historical exclusionary and exploitative employment practices. The study documents the experience and perceptions of institutional stakeholders in creating new knowledge on harmonisation following insourcing.Research approach/design and method: Employing a qualitative approach, 16 interviews were conducted with selected multi-level management and personnel directly involved in a harmonisation.Main findings: The study found tangible and intangible aspects, processes and other psychological perspectives on implementing harmonisation across employment levels. Furthermore, it was found that an efficient and effective harmonisation framework is required. Effective harmonisation for inclusion was viewed as being compromised by factors such as government intervention, and a lack of policy, framework and legislation to guide the process.Practical/managerial implications: Practical recommendations are provided for implementing harmonisation strategies following insourcing across employment levels in South African higher education institutions.Contribution/value-add: The study contributes to novel theory on harmonisation after insourcing and provides a management framework for harmonisation of conditions of employment.

Primary spinal cord neoplasms are rare, accounting for 1% of paediatric central nervous system tumours. The majority of which are low-grade gliomas (LGG). A teenage male presented with rapidly progressive lower limb paralysis. He subsequently underwent a near-total resection of an intramedullary thoracic tumour. Although the initial histopathology report suggested a LGG, closer review of the morphology and immunohistochemical staining revealed a diffusely infiltrating high-grade astrocytoma. Methylation profiling later confirmed a H3K27M-mutated spinal DMG. He underwent spinal radiation to the tumour bed soon after surgery but succumbed to his disease 8 days after completing radiation, and 3 months after presentation.Conclusion: Spinal DMGs are rare, can lead to diagnostic challenges and have a poor prognosis.

Abstract

Introduction:
Early childhood caries (ECC) is a significant worldwide oral health problem. Pediatricians can be a perfect source for children’s oral health promotion and disease prevention. Hence, the study was conducted to determine knowledge, attitude, and practice about early dental caries among pediatricians and pediatric residents.

Materials and Methods:
A questionnaire survey was conducted among 350 pediatricians and pediatric residents which covered aspects of knowledge, attitude, and practices regarding dental caries. The questionnaire consisted of 22 close-ended questionnaires. Data were tabulated and analyzed using SPSS software.

Results:
Most pediatricians had adequate knowledge regarding the appropriate age to start oral hygiene as well as performed visual oral examination but very few had instruments to diagnose dental caries. Only 37% of pediatricians advised dental visits below 1 year and only 27% advised the use of fluoridated toothpaste below 1 year.

Conclusion:
Most of the pediatricians had adequate knowledge and awareness of dental care and hygiene. The lack of dental knowledge and training during postgraduation limits the pediatricians’ role in promoting children’s oral health.
A Finite Element Study of Thermal Shock Load Effects on Dental Material before on the Two-body Wear Mechanisms
Authors: Yilmaz Efe Çetin 
Published: October 2024

Abstract

Background:
The thermal changes environment is a parameter that affects the dental mechanical and esthetic behavior of materials. Dental materials placed in the human oral environment are inevitably exposed to thermal changes environments during chewing movement and hot or cold fluids.

Aim:
Therefore, this study aims to analyze the surface behavior of a dental material placed in the human mouth in thermal changes according to the finite element method.

Materials and Methods:
Cylindrical titanium alloy samples with a diameter of 12 mm were prepared for thermal shock load simulation. Withinthe scope of this study, the samples were divided into two equal groups. While the first group test samples were subjected to thermal shock experiments, the others were determined as the control group. The surface temperature distributions of the samples in the test procedures were analyzed and evaluations were made on the wear behavior of the materials.

Results:
The temperature distributions showed density on the material surface and it was analyzed that a temperature transfer took place toward the inside of the material.

Conclusion:
This result is evaluated as behavior that reduces the wear resistance since it directly affects the contact surface in the two-body (direct-contact) wear mechanism.

Published: October 2024

Abstract

Background:
Periodontitis is a prevalent inflammatory condition leading to progressive attachment loss and potential tooth loss. Nonsurgical periodontal therapy, including scaling and root planing (SRP), ultrasonic therapy, and laser therapy, is essential in managing periodontitis. This study compares the clinical and patient-reported outcomes of these three treatment modalities to determine their relative effectiveness.

Objective:
We aimed to compare the clinical outcomes and patient-reported experiences of SRP, ultrasonic therapy, and laser therapy in patients with chronic periodontitis.

Materials and Methods:
This randomized controlled trial involved 126 participants with moderate-to-severe chronic periodontitis, randomly assigned to one of three groups (42 participants each): Group 1 (SRP), Group 2 (ultrasonic therapy), and Group 3 (laser therapy). Clinical outcomes, including clinical attachment level (CAL), probing depth (PD), and bleeding on probing (BOP), were measured at baseline and 3 months post-treatment. Patient-reported outcomes such as pain, discomfort, and satisfaction were assessed using a visual analog scale. Data were analyzed using analysis of variance, with a P < 0.05 considered statistically significant.

Results:
All groups showed significant improvements in CAL, PD, and BOP with no significant differences between groups (P > 0.05). Laser therapy resulted in the lowest pain and discomfort scores and the highest satisfaction (P < 0.05).

Conclusion:
SRP, ultrasonic therapy, and laser therapy are effective nonsurgical treatments for periodontitis, with comparable clinical outcomes. Laser therapy, however, offers superior patient comfort and satisfaction, suggesting that it may be a preferred option for patients sensitive to pain or discomfort.
Exploring the Biomechanical Factors Influencing the Success of Combined Prosthodontics and Implant Treatments, Including Load Distribution, Stress Distribution, and Material Selection
Authors: Nedumgottil Binoy Mathews , Nedumgottil Sajina Binoy 
Published: October 2024

Abstract

Background:
The success of combined prosthodontics and implant treatments is influenced by various biomechanical factors, including load distribution, stress distribution, and material selection. These factors play a critical role in determining the longevity and functionality of implant-supported prosthetic restorations.

Aim:
This study aimed to explore the biomechanical factors influencing the success of combined prosthodontics and implant treatments, focusing on load distribution, stress distribution, and material selection.

Materials and Methods:
A prospective observational study was conducted with a sample size of 30 patients requiring implant-supported prosthetic restorations. Standard titanium implants were placed, followed by the application of prosthetic components fabricated from materials such as zirconia, porcelain-fused-to-metal, monolithic zirconia, and composite resin. Cone-beam computed tomography and finite element analysis were used to assess the load and stress distribution. Intraoral sensors measured occlusal load, and data were collected at 3, 6, and 12 months post-prosthesis placement.

Results:
Posterior mandibular implants exhibited the highest mean occlusal load (220 N), with a significant variability among patients. Zirconia and monolithic zirconia prosthetics demonstrated the lowest mean stress (750 and 700 MPa, respectively) and no fracture incidents, whereas composite resin showed the highest mean stress (900 MPa) and the most fractures. These findings highlight the importance of appropriate material selection and biomechanical planning to prevent implant overload and prosthetic failure.

Conclusion:
Biomechanical factors, including load and stress distribution, along with careful material selection, are crucial for the success of implant-supported prosthetic restorations. Posterior regions, especially the mandible, require meticulous planning to distribute the occlusal forces evenly. Zirconia and monolithic zirconia materials are recommended for high-load areas due to their superior mechanical properties and fracture resistance.
Autorotation of the Mandible: A Truth or a Myth—A Review
Authors: Aboobacker Noora , Shetty Subramanya , Umar Dilshad , Koya Shafees , Shetty Sandeep 
Published: October 2024

Abstract
Autorotation of the mandible plays a pivotal role in various aspects of jaw function and biomechanics. As the lower jaw rotates, it not only facilitates chewing and speech but also contributes significantly to maintaining proper occlusion and dental health. Autorotation is intricately linked with the temporomandibular joint (TMJ), allowing for smooth and coordinated movement during mastication and other oral activities. Understanding the dynamics of autorotation is crucial in diagnosing and treating conditions such as temporomandibular disorders (TMDs), where disruptions in mandibular movement can lead to discomfort and dysfunction. Autorotation of the mandible underscores the complexity of the craniofacial system and its interaction with surrounding structures. Advancements in biomechanical research have shed light on the nuances of mandibular autorotation, aiding in the development of therapeutic interventions and orthodontic treatments aimed at restoring optimal jaw function. This review helps in understanding of mandibular growth pattern and associated growth rotation. It also focuses on various predict methods of autorotation of mandible following Lefort 1 for achieving the desired treatment goals.

Published: October 2024

Abstract

Objective:
The objective of this study is to evaluate the psychosocial effect of dental esthetics and determine its correlation with the severity of malocclusion among young adults.

Materials and Methods:
A sample of 297 Gujarati young adults aged from 18 to 24 years were selected randomly, and intraoral examination was done by calibrated examiners at their colleges. The Psychosocial effect of Dental Aesthetics was measured by using the Psychosocial Impact of Dental Esthetic Questionnaire (PIDAQ). The severity of malocclusion was measured through the Index of Orthodontic Treatment Need (IOTN). The data were analyzed using student’s t tests, analysis of variance (ANOVA), and Chi-square tests.

Results:
The results revealed that the total PIDAQ score and its four subscales, social impact, psychosocial impact, esthetic concern, and dental confidence, presented significant differences (P ≤ 0.05 by ANOVA) and linear relationship with the IOTN grades (P ≤ 0.05) and the psychosocial Impact subscale showed significant differences by gender.

Conclusions:
This study concludes that dental esthetics harm the psychosocial well-being of adults and when correlated with malocclusion it increases with the severity. The psychological impact is greater in females than in males.

Published: October 2024

AbstractThis paper presents a membrane computation error‐minimized mixed‐mode spiking neural network (SNN) crossbar array. Our approach involves implementing an embedded dummy switch scheme and a mid‐node pre‐charge scheme to construct a high‐precision current‐mode synapse. We effectively suppressed charge sharing between membrane capacitors and the parasitic capacitance of synapses that results in membrane computation error. A 400 × 20 SNN crossbar prototype chip is fabricated via a 28‐nm FDSOI CMOS process, and 20 MNIST patterns with their sizes reduced to 20 × 20 pixels are successfully recognized under 411 μW of power consumed. Moreover, the peak‐to‐peak deviation of the normalized output spike count measured from the 21 fabricated SNN prototype chips is within 16.5% from the ideal value, including sample‐wise random variations.
Quantum electrodynamical formulation of photochemical acid generation and its implications on optical lithography
Authors: Lee Seungjin 
Published: October 2024

AbstractThe photochemical acid generation is refined from the first principles of quantum electrodynamics. First, we briefly review the formulation of the quantum theory of light based on the quantum electrodynamics framework to establish the probability of acid generation at a given spacetime point. The quantum mechanical acid generation is then combined with the deprotection mechanism to obtain a probabilistic description of the deprotection density directly related to feature formation in a photoresist. A statistical analysis of the random deprotection density is presented to reveal the leading characteristics of stochastic feature formation.
