Dimensional relationships between the sphenoid sinus, maxillary sinuses and other craniomaxillofacial structures using cone-beam computed tomography analysis.

Introduction: The study investigated dimensional relationships between the sphenoid and maxillary sinuses and other selected craniomaxillofacial structures by using traditional cephalometric and volumetric procedures based on cone beam computed tomographic (CBCT) data. Methods and Materials: A retrospective three-dimensional (volumetric) and two-dimensional (conventional cephalometric) analyses were conducted on CBCT datasets of 27 subjects who met the inclusional criteria from a sampled database of 2,290 individuals. Subjects were divided into 3 groups: (1) pre- fused spheno-occipital synchondrosis \u3c 18 years (n=8), (2) fused spheno-occipital synchondrosis \u3c 18 years (n=9), and (3) = 18 years with fused spheno-occipital synchondosis (n= 10). Results: Differences between studied groups were found for linear and angular measurement. Specific correlations were found between certain topographic and internal measurements, and some sinus dimensions and other selected craniomaxillofacial structures. Conclusion: Dimensional correlations exist between the sphenoid and maxillary sinuses and development of other selected craniomaxillofacial structures

Effect of a Modified Stepped Osteotomy on the Primary Stability of Dental Implants in Type D4 Bone: A Cadaver Study

Purpose. The aim of this study was to examine the effect of an alternative surgical technique on endosseous dental implant stability parameters in Class D4 Bone. Significant differences between insertion torques (Ncm) produced by a conventional osteotomy verses a modified stepped osteotomy were examined. Significant differences between Implant Stability Quotients (ISQ) produced by a conventional osteotomy verses a modified stepped osteotomy were examined. Correlations between Hounsfield units (HU), Implant Stability Quotient (ISQ), and insertion torque (IT) were examined.;Materials and methods. Sixteen preserved cadaver heads were radiographically examined with a Toshiba AquilionRTM 64 Fast Whole Body Computerized Tomography (CT) Scanner. A total of 22 implants were placed in the maxillary bone of nine preserved cadavers which possessed Misch Class D4 bone with adequate volume for this study. The control group consisted of 11 conventional osteotomies. The test group consisted of eleven modified stepped osteotomies. The maximum insertion torque (Ncm) data were recorded with the Zimmer(TM) Implant Motor and confirmed with the Thommen(TM) Torque Driver. Implant Stability Quotient (ISQ) was measured with the Osstell Mentor(TM) (Integration Diagnostics AB, Goteborg, Sweden) via resonance frequency analysis. Significant differences insertion torques (IT) and Implant Stability Quotient (ISQ) were analyzed with a Wilcoxon Signed Rank Test. Correlations were analyzed with the Pearson Correlation Test.;Results. Maxillary cadaver bone utilized in this study ranged from 173.4--312.1 HU. The mean insertion torque in the conventional osteotomy group was 15.91 Ncm. The mean insertion torque in the modified stepped osteotomy group was 26.82 Ncm. A Wilcoxon Signed Rank test also showed the modified stepped osteotomy had a significantly greater mean insertion torque than the conventional osteotomy (S = 33.00 p = 0.0010). A Wilcoxon Signed Rank test also showed no significant difference between ISQ in the conventional osteotomy group and the modified stepped osteotomy test group (S = 17.00, p = 0.01475). Pearson correlations showed a significant positive correlation between the insertion torques in the conventional osteotomy test group and the modified stepped osteotomy test group (r = 0.817, p = 0.0021). Significant correlation between the ISQ in the modified stepped osteotomy and HU also found (r = 0.7099, p = 0.0144). There were no other significant correlations between HU and ISQ. There were no significant correlations between HU and IT. There were no significant correlations between the ISQ in the conventional osteotomy test group and the modified stepped osteotomy group. There were no significant correlations between ISQ and IT in the conventional osteotomies. There were no significant correlations between ISQ and IT in the modified stepped osteotomies.;Conclusion. Within the limits of the study, the following conclusion can be drawn: The modified stepped osteotomy resulted in significantly greater implant stability in terms of insertion torque (IT) than the conventional osteotomy in Misch Class D4 bone. Significant correlations were found between the insertion torque (IT) produced in the modified stepped osteotomy and bone density (HU). No other correlations between insertion torque (IT) and bone density (HU) were found. No correlation could be found between insertion torque (IT) and Implant Stability Quotient (ISQ). No correlation could be found between Implant Stability Quotient (ISQ) and bone density (HU)

INSTRUCTIONAL DESIGN, IMPLEMENTATION STRATEGIES, AND EVALUATION OF ANES 525 APPLIED ANATOMY FOR ANESTHESIA PRACTICE: TRANSFORMATION OF A DISSECTION-BASED BASIC SCIENCE COURSE INTO A TECHNOLOGY AND CLINICALLY BASED ANATOMY COURSE FOR ANESTHESIOLOGIST ASSISTANT STUDENTS

Due to perceived economic drain on Emory University Anesthesiologist Assistant (AA) Program resources, faculty, and students, administrators called for the anatomy course to eliminate cadaver laboratory. Simultaneously, administrators encouraged faculty to design AA courses with regard to the progressive medical education pedagogic transition from traditional lecture hall dissemination of information toward experiential learning via problem-based learning (PBL) and authentic activities. Additionally, progressive medical educators advocate for inclusion of medical technology in both clinical and didactic learning environments. So although dissection of cadavers has historically been the cornerstone of anatomy instruction, advancements in medical imaging, virtual cadaver software, and digital learning media suggest that a flipped and blended course of human anatomy is possible. This study documents the transformation of a graduate level dissection-based basic science course into a technology and clinically based anatomy course. Student achievement measured via pre/posttest design demonstrated significant increases in scores, which indicates that learning occurred. Student perceptions of teaching and learning materials and instructional methods measured by a Likert-type survey questionnaire revealed learning preferences and attitudes, and showed significant correlations between key questions to support instrument validity

Surf Biomechanics and Bioenergetics.

O surf moderno vem sendo descrito como uma atividade física intermitente, que varia em duração e intensidade, seguida de períodos de recuperação consideráveis. Atualmente, a análise e avaliação das sessões de surf são baseadas em conhecimento empírico, experiência e observação. Em outras palavras, procedimentos que envolvem grandes erros de medição. No entanto, é extremamente difícil obter informações analíticas sobre os parâmetros de desempenho. As primeiras investigações científicas no mundo do surf enfrentam uma dificuldade clássica do mundo da ciência, que é medir sem interferir. Além disso, o ambiente marítimo, particularmente devido à água salgada, é extremamente hostil aos componentes eletrônicos, que atualmente são a nossa maior fonte de informações quantitativas.O objetivo desta pesquisa foi investigar a fase horizontal do surf, especificamente a remada de potência, a remada de longa duração e a técnica de transição para ficar de pé na prancha de surf. Todo este pacote sob a perspetiva da biomecânica, associado a alguns parâmetros bioenergéticos. A abordagem geral foi apoiada por um processo de desconstrução dos movimentos e técnicas em partes didáticas, a fim de reconstruir um conhecimento global e uma melhor compreensão do surf. Olhando para o futuro, agregámos a este projeto o desenvolvimento de recursos tecnológicos que possibilitam explorar o surf diretamente no oceano. Tudo isso ganha ainda muito mais peso, desde que o Surf foi selecionado como novo desporto olímpico para os Jogos de Tóquio, em 2020. Os Jogos Olímpicos passam a ser uma excelente oportunidade, onde o surf se tornará mais profissionalizado e organizado. Neste contexto, as métricas para avaliação de desempenho são importantes para ajudar a validação de metodologias de ensino-aprendizagem, treinamento e julgamentos competitivos.Palavras-chave: biomecânica do surf, surfing, remadas do surf, ficar de pé, medições.Modern surfing has been described as an intermittent physical activity, which varies in duration and intensity, followed by considerable recovery periods. Currently, the analysis and judgment of surf sessions are based on empirical knowledge, experience, and observation. In other words, procedures that involve great measurement errors. However, it is extremely difficult to obtain analytical information on performance parameters. The first scientific investigations in the surf world faced a classic difficulty of the world of science, which is to measure without interfering. In addition, the maritime environment, particularly due to salt water, is extremely hostile to electronic components, which are currently our largest source of quantitative information.This research aimed to investigate the horizontal phase of surfing, specifically the sprint paddling, endurance paddling and the transition pop-up - standing technique. The whole pack under a biomechanics perspective, associated with bioenergetic parameters. The general approach was supported by process of deconstruction of movements and techniques in didactic parts, in order to reconstruct a global knowledge, and a better understanding of surfing. Looking to the future, we aggregate to this project the development of technological resources that make it possible to explore surf directly in the ocean. All this gained even more relevance since Surf has been selected as the new Olympic sport for the next Games of Tokyo 2020. The Olympic Games are an excellent opportunity where surfing will become more professional and organised. In this context, the metrics for performance evaluation are important to help validating teaching-learning methodologies, support training and competitive judgments
