Avaliação da amplitude dos movimentos mandibulares por um sistema de ultrassom 3D no pré e pós tratamento de indivíduos com disfunção temporomandibular / Amplitude of mandibular movements evaluation by 3D ultrasound system in pre and post treatment of subjects with temporomandibular disorders

Anacleto, Mateus Aparecido 26 June 2015 (has links)
Disfunções Temporomandibulares e Dor Orofacial ou DTM, referem-se a um conjunto de alterações funcionais e/ou estruturais que se manifestam nas articulações temporomandibulares (ATMs), nos músculos da mastigação e nas estruturas associadas que compõem o aparelho mastigatório (Okeson, 2013). A DTM tem o potencial de não só interferir nas atividades funcionais do sistema estomatognático, mas também de afetar o comportamento social e psicológico do indivíduo. Este trabalho avaliou a amplitude dos movimentos mandibulares e a dor a palpação muscular no pré e pós-tratamento de participantes com DTM. Os participantes incluídos na pesquisa responderam ao Research Diagnostic for Temporomandibular Dysfunction (RDC/TMD) para viabilizar a formulação do diagnóstico de DTM e qualificar a dor a palpação dos músculos faciais, e submetidos à análise dos movimentos através de uma análise 3D, o JMA que avalia os movimentos mandibulares por vias ultrassônicas, no pré e póstratamento com placa estabilizadora por 30 e 60 dias. Os participantes foram reavaliados, com o objetivo de saber se haverá uma melhora na amplitude dos movimentos mandibulares pela abertura, lateralidades e protrusão e da movimentação condilar dentro da cavidade articular no plano sagital e frontal. Os resultados demonstraram não ter diferenças estatísticas na maior parte dos movimentos excursivos mandibulares (abertura, lateralidade e protrusão) avaliados tanto pelo sistema de ultrassom JMA quanto pelo exame do RDC/TMD. Na análise descritiva dos resultados obtidos através da palpação dos músculos na aplicação do RDC/TMD observamos uma grande melhora no quadro clinico de dor a palpação após 60 dias de uso da Placa Oclusal estabilizadora. Também não observamos diferenças estatisticamente significantes entre os dados coletados de amplitude dos movimentos pelo sistema informatizado JMA e pelo questionário RDC/TMD, ou seja, podemos afirmar que a avaliação pelo JMA é precisa e confiável. / Temporomandibular Disorders and Orofacial Pain or TMD, refer to a set of functional and / or structural changes that are manifested in the temporomandibular joints (TMJ) in the masticatory muscles and associated structures that make up the masticatory system (Okeson, 2013). The TMD has the potential to not only interfere with the functional activities of the stomatognathic system, but also affect the social and psychological behavior of the individual. This study evaluated the range of mandibular movements and muscle palpation pain in the pre and post-treatment of participants with TMD. Participants included in the study responded to the Research Diagnostic for Temporomandibular Dysfunction (RDC / TMD) to allow the formulation of a diagnosis of TMD and qualify pain palpation of the facial muscles, and subjected to analysis of movement through 3D JMA assessing movements mandibular by ultrasonic means, before and after treatment with stabilizing plate for 30 and 60 days. Participants were reassessed in order to know if there will be an improvement in the range of mandibular movements for opening, laterality and protrusion and condyle movement within the joint cavity in the sagittal and frontal plane. The results showed no statistical differences have in most excursive mandibular movements (opening, lateral and protrusive) assessed both by JMA ultrasound system as the examination of the RDC / TMD. In the descriptive analysis of the results obtained by palpation of the muscles in the application of the RDC / TMD noticed a great improvement in the clinical picture of pain palpation after 60 days of use board stabilizing occlusal. We did not observe statistically significant differences between the data collected from the range of motion by the computerized system JMA and the questionnaire RDC / TMD, other words, we can say that the evaluation by the JMA is accurate and reliable.

Skills development for the social reintegration of offenders : a case-study of Johannesburg management area / Tryphina Zanele Khatle

Khatle, Tryphina Zanele January 2011 (has links)
The Department of Correctional Services (Johannesburg Management Area) is established in the South of Johannesburg in Gauteng Province. It was founded in 1982. According to the Annual Report of the Department of Correctional Services 2009, the institution was initially developed to house 2630 offenders. Presently it accommodates 10130 offenders. These offenders are dependent on the number of facilities and officials for rehabilitation purpose. The discrepancy in the number of officials to that of offenders is a challenge within the Department of Correctional Services with regard to skills development. The study was based on the hypothesis that “effective implementation of skills development within Johannesburg Management Area may lead to a successful social reintegration of offenders”. The empirical research was conducted to support the hypothesis. Questionnaire was distributed and interviews were conducted to obtain responses. the findings reveal that offenders who are skilled are easy to be reintegrated and at the same time skilled officials are able to play a vital role in facilitating the social reintegration of offenders Study further reveals that skilled officials are able to network on behalf of offenders with ease and are able to increase job opportunities for offenders who are already on social reintegration programme. The study recommends that the Johannesburg Management area need to restructure its human resource development office, ensure that experienced and qualified facilitators are employed. Each correctional centre should have qualified facilitators who are experienced in adult education to skill offenders in various areas of development. The study leaves a scope for future research stating that Department of Correctional Services do further analysis on skills development and Social reintegration of offenders nationally to find a common and standard approach that will assist in the full reintegration of offenders / M, Development and Management, North-West University, Vaal Triangle Campus, 2011

Johnson-Mehl-Avrami Kinetics of Intracellular Ice Formation in Confluent Tissue Constructs

Sumpter, Megan Louise 06 May 2004 (has links)
In an effort to minimize the harmful effects of intracellular ice formation (IIF) during cryopreservation of confluent tissues, computer simulations based on Monte Carlo methods were performed to predict the probability of IIF in confluent monolayers during various freezing procedures. To overcome the prohibitive computational costs of such simulations for large tissues, the well-known Johnson-Mehl-Avrami (JMA) model of crystallization kinetics was implemented as a continuum approximation of IIF in tissues. This model, which describes nucleation, growth, and impingement of crystals in a supercooled melt, is analogous to the process of intracellular ice formation and propagation in biological tissues. Based on the work of Weinberg and Kapral (1989), the JMA model was modified to account for finite-size effects, and was shown to predict accurately the results of freezing simulations in 1-D tissue constructs, for various propagation rates and tissue sizes. An initial analysis of IIF kinetics in 2-D tissues is also presented. The probability of IIF in 2-D liver tissue was measured experimentally during freezing of HepG2 cells cultured in monolayers, and compared to Monte Carlo simulations and predictions of the continuum model. The Avrami coefficient and exponent for IIF in HepG2 tissue were estimated to be k = 0.19 and n = 0.45.
