Title: Kinesiologic analysis of function of selected upper limb muscles after female breast augmentation Objectives: The aim of this research is to analyze the functionality and scope of involvement of the injured muscles due to plastic surgical augmentation procedure at pre-selected physical activities before and after surgery a few months later (specifically, three months - the time the patient left the recovery) using a noninvasive surface electromyography (EMG). Methods: A Case Study measuring method of noninvasive surface electromyography in combination with the method of temporal phase shifts involved in the activation of muscle movement, accompanied by a support method of integrated EMG. Results: There differences have been observed in the timing of individual muscles measured during performing selected testing exercises before and after completion of the augmentation plastic surgery operatios. Furthermore, the possibility of the loss of muscle strength has been detected by some measured muscles and this has the potential to take over functions of damaged muscles. Key words: plastic surgery, female breast augmentation, surface electromyography, upper limb muscles, musculus pectoralis major

We propose a new approach for defining mechanical properties of the brain tissue in-vivo by taking MRI or CT images of a brain response to ventriculostomy operation, i.e., the relief of the elevated pressure in the ventricular cavities. Then, based on 3-D image analysis, the displacement fields are recovered from these images. Constitutive parameters of the brain tissue are determined using inverse analysis and a numerical method allowing for computations of large strain deformations. We tested this approach in controlled laboratory experiments with silicone brain models mimicking brain geometry, mechanical properties, and boundary conditions. The ventriculostomy was simulated by inflating and deflating internal cavities that model cerebral ventricles. Subsequently, the silicone brain model was described by a hyperelastic (neo-Hookean) material. The obtained mechanical properties have been verified with direct laboratory tests. Properties of real brain tissue are more complicated, but the proposed approach requires only conventional medical images collected before and after ventriculostomy. Breast cancer is the second most prevalent cancer in women, and an operative mastectomy is frequently a part of the treatment. Women often choose to follow a mastectomy with a reconstruction surgery using a breast implant. Furthermore, there is a growing demand for breast augmentation for the sake of aesthetic improvement. In this dissertation, we also developed a quantitative large-strain 3-D mechanical model of female breast deformation. The results show that the stiffness of skin and the constitutive parameters of the breast tissue are important factors affecting breast shape. Our results also suggest that the published Mooney-Rivlin parameters of breast tissue are underestimated by at least one or two orders of magnitude. Scale analysis, representing female breast as a cantilever beam, confirms these conclusions. Subdural hematoma (tearing and bleeding between scull and brain) is one of the major complications of the ventriculostomy operations. Understanding the mechanism of subdural hematoma is critically important for development of more effective medical treatments. In this work, we developed a simple, spherically-symmetrical poroelastic model of the ventriculostomy operation and studied brain response to the pressure change in the ventricles. The observed effect of the material properties on the occurrence of subdural hematoma may be useful for making clinical decisions.

Nos casos de mulheres com câncer de mama, denota um caráter emergencial em virtude do elevado número de ocorrências ou pela falta de percepção feminina da doença, o que dificulta a prevenção e o tratamento em tempo hábil. Este estudo pretende analisar como e de que maneira ocorrem e repercutem as práticas discursivas entre os profissionais da saúde e as pacientes com câncer de mama. Para isso, delineamos como pressupostos teóricos as barreiras da comunicação, seja interpessoal, intrapessoal e não verbal. A metodologia foi com base na Teoria das Representações Sociais de Serge Moscovici e no Discurso do Sujeito Coletivo (DSC) de Ana Maria Cavalcanti Lefévre e Fernando Lefévre. Nas análises dos relatos das mulheres com câncer de mama, identificamos conflitos de ordem sociocultural, como crenças, valores pessoais, estereótipos, enfim, distorções provenientes do senso comum e do imaginário coletivo, disseminadas nas representações da doença levadas a público pela mídia em geral. Nas considerações finais, constatamos que tais representações (estigmas sociais) interferem na relação com os profissionais de saúde, influenciando, assim, a adesão ao tratamento da doença. Os aspectos comunicacionais são aqui apontados de maneira tácita.
