PAIN MEASUREMENT AND MANAGEMENT IN PEOPLE WITH KNEE OSTEOARTHRITIS

Negm, Ahmed M. 10 1900 (has links)
<p>The purpose of this thesis was to improve the understanding of pain measurement and management in people with knee OA through: 1) Developing a theoretical model that may help in pain management and measurement; 2) Exploring the knee OA individuals’ views about three pain measures and 3) To determine if low frequency (≤100 Hz) pulsed subsensory threshold electrical stimulation produced either through pulsed electromagnetic field (PEMF) or pulsed electrical stimulation (PES) versus sham PEMF/PES intervention is effective in improving pain and physical function in the knee OA population.</p> <p>After pain theories literature review, a theoretical model was developed to address the gap between pain theories and clinical pain measurement and management. The patient’s views about three pain measures were not explored before 96 participants were recruited and completed the Verbal Numerical Rating Scale (VNRS), Intermittent and Constant Osteoarthritis pain Questionnaire (ICOAP) and the Short Form-McGill Pain Quetionnaire-2 (SF-MPQ-2). Participants were asked how well each pain measure describes their pain on a 10 cm Visual Analogue Scale (0 = does not describe your pain at all, and 10 = describes your pain completely. The time taken to complete and score the pain measure as well as the number of errors and questions while filling the pain measures were recorded. Systematic electronic searches were performed. Duplicate title, abstract and full text screening, risk of bias assessment, data extraction and grading the quality of evidence were performed. Data analysis was performed using Revman 5 software.</p> <p>Our sample of individuals with knee OA showed that VNRS, SF-MPQ-2 and ICOAP describe knee OA pain experience with no preference of one over the others. The systematic review conclusion was that PEMF/PES may be beneficial to improve physical function but not pain in people with knee OA with low and very low quality of evidence respectively</p> / Master of Health Sciences (MSc)

Falhas ósseas são comumente encontradas na medicina veterinária em diferentes enfermidades, principalmente por traumas em grandes animais. Frequentemente faz-se necessário auxiliar este reparo tecidual para melhor correção desta falha. Os biomateriais foram desenvolvidos para cumprir esta função. A fim de avaliar o comportamento celular perante estes substitutos ósseos, a realização de testes in vivo é fundamental. A partir da observação da unidade morfofuncional do tecido é possível avaliar a quantidade e a qualidade do tecido neoformado. Atualmente, em estudos ortopédicos, os ovinos são considerados animais de escolha como modelo experimental. Falhas ósseas foram realizadas experimentalmente em ovinos, onde foram implantados biomateriais à base de quitosana, hidroxiapatita e colágeno. Após 60 dias foi realizada biopsia no local do reparo tecidual e por meio da histomorfometria, da análise descritiva da microscopia de luz e da microscopia eletrônica de transmissão, o tecido neoformado foi avaliado e comparado. Na histomorfometria, não houve diferença significativa quanto à quantidade de tecido neorformado do grupo controle e do grupo com biomaterial, porém quando comparado ao osso pré-existente, retirado no momento da confecção da falha, a área de matriz óssea foi menor. Na descrição da microscopia de luz e em maiores detalhes na análise ultra estrutural, observou-se o biomaterial em contato íntimo com o tecido neoformado, sugerindo boa biocompatibilidade. Foi possível observar o padrão da reparação tecidual, onde o membro controle e o membro com biomaterial não diferiram quanto à arquitetura tecidual, porém nas amostras com o implante do biomaterial foi identificada a presença do mesmo. Todas estas informações sugerem que o biomaterial de estudo apresenta potencial para auxiliar na rotina ortopédica de grandes animais. / Bone defects are commonly found in veterinary medicine through different disease such as trauma, especially in large animals. Frequently it is necessary to assist this tissue repair for better regeneration. Biomaterials in general are designed to this function. In order to understand the bone cells in the presence of bone substitutes, tests in vivo are essential for these studies. The quantity and quality of new tissue formation can be assessed by observation of tissue morphofunctional unit. Currently, in orthopedic studies sheep are considerated animals of choice for experimental development. Bone defects were performed experimentally in sheep and were implanted chitosan, hydroxyapatite and collagen biomaterials. After 60 days, biopsy was performed at the site of tissue repair and the new tissue formation was described, evaluated and compared by histomorphometry and electronic transmission microscopy. After hystomorfometry analysis there was no difference between control group and biomaterial group, but when compare with pre-existent tissue, the values are smaller. In descriptive analysis was observed intimate contact with biomaterial and new tissue formation suggesting biocompatibility. It observed the pattern of tissue repair in control group and biomaterial group did not differ in the architecture tissue. However, in the biomaterial group was identified presence of the biomaterial in the specimen. All these data suggest that the biomaterial study has the potential to assistant in orthopedic routine of large animals.

Estudo comparativo cefalométrico dos efeitos dentoesqueléticos decorrentes do tratamento com dois tipos de aparelhos de Herbst e um grupo controle, em adolescentes com retrognatismo mandibular / Comparative evaluation of cephalometric dentoskeletal effects resulting from treatment with two types of Herbst appliances and a control group, in adolescents with mandibular retrognathism

Marchi, Luiz Carlos 02 August 2013 (has links)
Neste estudo retrospectivo, controlado, de 94 adolescentes consecutivos com maloclusão de Classe II, divisão 1ª de Angle e retrognatismo mandibular, no surto de crescimento puberal, foram avaliadas as mudanças dentoesqueléticas decorrentes do tratamento com aparelho de Herbst (Grupo A coroas de aço e B splints acrílicos) e de acompanhamento (Grupo C - controle), em um período de 12 meses. As telerradiografias laterais foram obtidas em T1 (inicial) e T2 (no final do período de observação). As variáveis cefalométricas foram analisadas com testes paramétricos. Os resultados mostraram que os dois grupos tratados caracterizaram-se diferencialmente do grupo controle, com restrição do crescimento maxilar e maior crescimento mandibular, o que permitiu melhorar a relação sagital. Da mesma forma, no aspecto dentoalveolar houve melhora da sobressaliência pela retroinclinação dos incisivos superiores e vestibularização dos incisivos inferiores, distalização com controle vertical dos molares superiores e mesialização dos molares inferiores. Os três grupos mostraram semelhança na extrusão dos molares inferiores, na preservação da morfologia mandibular e do padrão facial. O plano oclusal rotacionou no sentido horário nos grupos tratados e anti-horário no grupo controle. Pode-se concluir que no tratamento com dois tipos de aparelho de Herbst da maloclusão de classe II, em adolescentes no pico máximo de crescimento, observaram-se um conjunto de mudanças que melhoraram as relações dentoesqueléticas sagitais, independentemente do crescimento. No aspecto vertical, apesar das pequenas mudanças observadas houve preservação do padrão facial assim como no grupo controle. / This retrospective controlled study enrolled 94 consecutive adolescents during growth spurt with Angle class II division 1 malocclusion and mandibular retrognathism and evaluated skeletal and dental changes resulting from treatment with a Herbst appliance (Group A: steel crowns; Group B: acrylic splints) and compared them with results of a follow-up group (Group C: control) for 12 months. Lateral radiographs were obtained in the beginning of the treatment (T1) and at the end of the observation period (T2). Cephalometric variables were analyzed using parametric tests. The results of the two treatment groups were different from those found for the control group. Maxillary growth was restricted, whereas mandibular growth was greater, which resulted in a better sagittal relation. At the same time, the analysis of dentoalveolar aspects revealed that overjet was reduced due to distal tipping of maxillary incisors and buccal inclination of mandibular incisors, vertical control of maxillary molars and mesial movement of mandibular molars. The three groups had similar extrusion of mandibular molars, preservation of mandibular morphology and facial pattern. The occlusal plane rotated clockwise in the treated groups and counterclockwise in the control group. It can be concluded that the treatment of class II malocclusion in adolescents during growth spurt with two types of Herbst appliance resulted in a set of changes that improved sagittal skeletal and dental relations, regardless of growth. Vertically, facial pattern was preserved in treatment and control groups, despite some small differences.

Estudo retrospectivo das alterações radiográficas em touros atletas com afecções ortopédicas /

Cholfe, Bruno Fornitano. January 2012 (has links)
Orientador: Celso Antônio Rodrigues / Banca: Ana Liz Garcia Alves / Banca: Luis Cláudio Lopes Correia da Silva / Resumo: No Brasil é crescente o número de bovinos utilizados na prática de esportes. Assim como o cavalo atleta, o bovino atleta fica sujeito a lesões ortopédicas, que a semelhança do equino, podem ser relacionadas com a modalidade esportiva. Apesar destas lesões serem amplas e exaustivamente estudadas nos equinos os estudos referentes à etiopatogenia, diagnóstico e tratamento na espécie bovina, necessitam ser incrementados. Os objetivos deste estudo foram: realizar um estudo retrospectivo dos achados radiográficos de touros atletas, acometidos de claudicação; estabelecer quais as lesões que acometem os touros atletas, correlacionado as afecções com o peso, idade, membro acometido e região do membro. Foram avaliadas 151 imagens radiográficas de 136 touros atendidos no Hospital Veterinário Dr. Halim Atique - UNIRP variando sua idade entre 4 a 13 anos, com peso médio de 800 kg e comprovada atividade física prévia, mediante participações em rodeios. Observou-se que 71,6% dos touros estudados e acometidos de claudicação, possuíam lesão radiográfica, com predomínio nos animais experientes. As enteseopatias nos touros iniciantes e experientes, artrite séptica nos iniciantes, fraturas e doença articular degenerativa nos experientes, foram as mais frequentes lesões radiográficas diagnosticadas. Os membros pélvicos foram os mais acometidos nos animais jovens, enquanto nos animais adulto a distribuição da lesão entre os membros foi equilibrada. A região do membro onde ocorreram a maioria das alterações radiográficas foi o dígito. Os fatores de risco e a ocorrência de afecções do aparelho locomotor, aos quais os touros atletas são submetidos, fazem com que as lesões se assemelhem aquelas citadas na literatura para os equinos de esporte. Este estudo possibilitou formar uma base de dados para pesquisa na área da medicina veterinária esportiva de bovinos atletas / Abstract: In Brazil, there is a growing number of bovine animals used in sports Just as the athletic horse, the athletic bovine shall be subject to orthopedic injuries, that, similar to the horse, may be related to the Sport modality. Although these lesions are extensive and thoroughly studied in equine, studies regarding the pathogenesis, diagnosis and treatment in the bovine species, need to be increased The objectives of this study were to establish a database for future research and demonstrate which lesions affect the athlete bulls, correlating the disorders with weight, age, affected limb and its region. Radiographic images were evaluated for 136 bulls who were taken care of at the Veterinary Hospital Dr. Halim Atique - UNIRP, ranging in age from 4 to 13 years, with an average weight of 800 kg and proven prior physical activity through participation in rodeos. It was observed that 71.6% of bulls studied and suffering from lameness, had radiographic lesions, predominantly in experienced animals the enthesopathy in starters and experienced bulls, septic arthritis in starters bulls, fractures and degenerative joint disease in experienced bulls, were the most frequent radiographic lesions diagnosed. The pelvic limbs were the most affected in starters animals, while in experienced animals the distribution of injuries among the members was balanced. The region of limb where the majority of radiographic changes occurred was the digits. Risk factors and occurrence of diseases of the locomotor system, to which athlete bulls are subjected, are similar to those of sports equines Risk factors and occurrence of diseases of the locomotor system, to which athlete bulls are subjected, are similar to those of sports equines / Mestre
