Vinte e nove pacientes submetidos ao Transplante de Medula Óssea Alogênico foram analisados num estudo dirigido às transfusões de hemocomponentes, desde o período pré-transplante até o momento da alta hospitalar, que na maioria das vezes coincidiu com a independência às transfusões. Não houve um padrão único de requerimento transfusional e os fatores que determinaram este fato foram múltiplos. O tipo de doença de base, intercorrências clínicas e a presença da Doença do Enxerto Versus o Hospedeiro estiveram relacionados. As técnicas laboratoriais empregadas na rotina de avaliação dos pacientes ofereceram subsídio adequado, para em conjunto com o exame clínico, proporcionarem parâmetros decisivos na indicação das transfusões sangüíneas. Alguns pacientes apresentaram incompatibilidade ao sistema de grupo sangüíneo ABO com os seus respectivos doadores de medula, fato que não impediu a realização do transplante, devido ao emprego de métodos que permitiram superar esta dificuldade. Foi observada refratariedade às transfusões de concentrados de plaquetas em poucos pacientes da casuística, atribuída à presença de anticorpos contra antígenos do sistema de histocompatibilidade leucocitária humana (HLA). As transfusões de plaquetas obtidas de doadores com o sistema HLA compatível, membros familiares, foram eficazes nestes casos. O tempo de recuperação da função hematopoética da medula transplantada foi similar ao descrito na literatura. / 29 patients who underwent Allogeneic Bone Marrow Transplantation (Allo BMT) were analyzed regarding the need for transfusion of blood components from admission the date of discharge. Most of the time the discharge coincided with blood components transfusion independence. There was no specific pattern of blood products transfusion among these patients. The need for transfusion could be ascribed to the presence of several factors like baseline disease, clinical complications and graf versus host disease. Routine clinical parameters and laboratory techiniques were adequate to indicate the need for transfusion of blood components. Some of the patients were ABO incompatible with their respective marrow donors.

Stroke is a common and multifaceted disease that often involves motor deficits in the upper limb. This thesis investigated reliability and validity of existing clinical assessments of upper limb function in persons with post-stroke symptoms and in non-disabled controls. Study I was conducted in a clinical setting where the Motor Evaluation Scale of Upper Extremity in Stroke patients (MESUPES) was assessed in persons post-stroke by two physiotherapists selected from a group of four.  Study II-IV took place in a motion analysis laboratory with an optoelectronic system. Kinematic measures and clinical measures were used to investigate the validity of the Arm Posture Score (APS), the Finger-to-Nose test (FNT), and the Standardised Nine Hole Peg test (S-NHPT) in persons post-stroke and non-disabled controls.   The results showed that the MESUPES had a high inter-rater reliability while the concurrent validity was not fully confirmed. MESUPES has a maximum score of 58 and the minimal detectable change ranged from 5 to 8 for a confidence level of 80% and 95%. The Arm Posture Scores, which include either four or six arm movement variables, were able to distinguish between the affected and non-affected arms, as well as between the affected arm and the non-dominant arm of the controls. The total movement time of the FNT, which is a coordination test, was able to distinguish persons post-stroke from controls, at least at a group level. Movement smoothness, accuracy and compensation, obtained from kinematic analysis, were the most discriminative variables for the FNT. Smoothness was most strongly correlated with the timed FNT and had the greatest association with the variance of the timed FNT. For the S-NHPT, which is a dexterity test involving grasping and reaching, the movement times, smoothness and compensation discriminated between the stroke group and the control group. Persons post-stroke spent considerably more time in the grasp-related parts of the task compared to controls. Smoothness and upper limb impairments had the strongest correlation with the S-NHPT.   In conclusion, the clinical measures used within stroke rehabilitation seem valid and reliable, although some limitations are highlighted by the kinematic assessment. MESUPES was shown to be a reliable assessment of upper limb movement quality after stroke. The kinematic analysis revealed that the timed FNT does not have sufficient discriminative validity at an individual level. The timed FNT reflected speed-related aspects of pointing movements such as smoothness and length of the deceleration phase, but should not be used as an overall measure of upper limb coordination after stroke. The timed S-NHPT demonstrated sufficient discriminative validity and reflected smoothness and upper limb impairments. For both the FNT and S-NHPT, kinematic analysis showed that the clinical outcomes of those tests (time of performance) did not adequately detect qualitative aspects of the upper limb movements after stroke such as possible compensatory movements. Therefore, clinical assessments that capture qualitative aspects of upper limb movements would improve the assessment of upper limb coordination and dexterity after stroke. In addition, 3D movement analysis provided unique information about upper limb function after stroke, not least in persons with mild post-stroke impairments. The APS, for instance, which quantifies how much the arm swing during gait deviates from normal, discriminated between persons with stroke and non-disabled persons. Such subtle deviations are not possible to quantify with the human eye.

Resumo: As enteroparasitoses comumente afetam o equilíbrio orgânico dos animais de estimação, sendo isto particularmente preocupante em relação aos cães, devido ao intimo contato destes com o homem. As técnicas coproparasitológicas usualmente utilizadas na rotina laboratorial para detecção de parasitoses gastrintestinais são indispensáveis para o diagnóstico e por conseqüência para determinar a necessidade de tratamento dos animais infectados. Neste estudo objetivou-se avaliar a ocorrência de helmintoses e protozooses em cães domiciliados e sua associação com faixa etária, sexo e raça, bem como a eficiência dos Métodos Willis- Mollay, Faust, Sedimentação e Exame Direto quanto a recuperação de ovos e oocistos de parasitos gastrintestinais da espécie canina. Foram processadas 401 amostras fecais, sendo que em 300 foi efetuada a Técnica de Kinyoun para pesquisa de Cryptosporidium spp. Os parasitos encontrados foram Ancylostoma spp. em 53,1%, Toxocara canis em 20,7%, Cystoisospora ohioensis em 15,7%, Trichuris vulpis em 3,7%, Dipylidium caninum em 2,5%, Cryptosporidium spp. em 1,33% e Taenia spp. em 1,0% das amostras. A positividade para Ancylostoma spp. não foi influenciada pelas variáveis raça, sexo e idade. Houve diferença estatisticamente significativa para T. canis e C. ohioensis nos cães com até seis meses de idade quando comparados a animais acima de seis meses (P<0,0001). Quanto a variável sexo houve associação apenas com o ascarídeo T. canis com maior ocorrência nos machos quando comparado as fêmeas (P = 0,0243). A associação da presença das formas evolutivas dos parasitos com raça dos cães não foi estatisticamente significativa. / Abstract: The enteroparasitoses generally affect the organic equilibrium of pets, being particularly worrying referring to dogs, due to intimate contact with the human being. The techniques coproparasitologics usually used in laboratorial routines for detection of gastroenteric parasitoses are indispensable for the diagnosis and consequence to determine the necessary of infected animals treatment. In this study we evaluated the occurrence of helminthoses and protozooses in dogs and its association with age, sex and race, as well as the efficiency of Willis-Mollay, Faust, Sedimentation and exam Direct methods. It was processed 401 fecal samples, being accomplished in 300 parts, the technique of Kinyoun for directed research of Cryptosporidium spp. The parasite found were Ancylostoma spp. (53.1%), Toxocara canis (20.7%), Cystoisospora ohioensis (15.7%), Trichuris vulpis (3.7%), Dipylidium caninum (2.5%), Cryptosporidium spp. (1.33%) and Taenia spp. (1.0%). There was a statistically significant difference for T. canis and C. ohioensis in dogs up to six months old (P<0,0001). The occurrence of T. canis was statistically bigger in males when compared to females (P=0,0243). The association of parasites with race was not statistically significant. Of the four dogs (1.33%) positives for Cryptosporidium spp., only one presented a semi liquid consistence faeces and light dehydration (5 to 7%), having this animal age superior to six months old, with simultaneous infection for Ancylostoma spp. The Willis-Mollay was more efficient in the diagnosis of Ancylostoma spp. and T. canis eggs. The Direct method was least efficient. The techniques were statistically the same as the occurrence of the C. ohioensis oocysts. / Orientador: Silvia Helena Venturoli Perri / Coorientador: Kátia Denise Saraiva Bresciani / Banca: Alessandro Francisco Talamini do Amarante / Banca: Solange Maria Gennari / Mestre

O tempo preciso do uso diário das moldeiras/produto clareador foi mensurado por meio de um microssensor TheraMon (Sales Agency Gschladt, Hargelsberhg, Áustria). Sessenta e seis voluntários, de ambos os gêneros, com idades entre 18 e 22 anos foram selecionados e distribuídos aleatoriamente em três grupos de estudo (n = 22), os quais receberam as informações sobre a presença do microssensor em suas moldeiras. O fator estudado foi o tempo de uso das moldeiras em três níveis: 2 (GI), 4 (GII) e 8 (GIII) hrs/dia. Para a análise clínica, as variáveis de resposta foram: grau de cooperação diária dos voluntários de acordo com o tempo de uso diário das moldeiras; grau de satisfação dos voluntários com o clareamento dental; eficácia do clareamento dental nos incisivos e caninos superiores e inferiores pelo método visual (Vita Classical) e digital (Vita Easyshade), assim como o grau de sensibilidade dental que foi avaliado com método analógico-visual. Os voluntários foram avaliados no período inicial (baseline), aos 7, 14 e 21 dias após o início do tratamento clareador e 14 dias após apenas para as observações da cor, sensibilidade e grau de satisfação. Os dados foram analisados com aplicação do teste ANOVA e pelo post test...

South Jordan, USA) for 21 consecutive days for 2, 4 and 8 hours/day. The wear time of acetate trays/dental bleaching was measured through a TheraMon microsensor (TheraMon® microelectronic system; Sales AgencyGschladt, Hargelsberhg, Austria). Sixty six volunteers, both sexes, with ages ranging from 18 to 22 years were selected and randonly distributed into 3 study groups (n=22). The volunters received information about presence of the microsensor in their trays. The fator studied was the wear time of the trays in three levels: during 2 (GI), 4 (GII) and 8 (GIII) hours/day. For the clinical analysis the response variables were: the degree of daily cooperation of the volunteers as the wear time/daily of the trays, microelectrically collected by micro sensor TheraMon®; the degree of satisfaction of volunteers with dental bleaching; the effectiveness of dental bleaching in the upper and lower incisors and canines teeth, by the visual method (Vita Classical) and digital (Vita Easyshade) and dental sensitivity was evaluated by the volunteers with a scale visual analog method on a scale of 0 to 10. The volunteers were evaluated at baseline period, at one, two and three weeks after the beginning of the bleaching treatment, and again ... (Complete abstract click electronic access below) / Mestre
