Comparação entre metodologias de controle de qualidade em mamografia digital

The best way to detect breast cancer is by screening mammography. The mammography equipments are dedicated and require a rigorous quality control in order to have a good quality image and to early detect this disease. The digital equipment is relatively new in the market and there isn’t a national rule for quality control for several types of digital detectors. This study has proposed to compare two different tests manuals for quality control provided by the manufacturers of digital mammography equipments, and also compare them to the “European guidelines for quality assurance in breast cancer screening and diagnosis “(2006). The studied equipments were: Senographe 2000D from General Electric (GE) and the Hologic Selenia Lorad. Both were digital mammography equipments, the GE unit presents an indirect digital system and the other presents a direct digital system. Physical parameters of the image have been studied, such as spatial resolution, contrast resolution, noise, signal-tonoise ratio, contrast-to-noise ratio and modulation transfer function. After that, a study of the importance of quality control and the requirement to implement a Quality Assurance Program has been done. One data collection was done to compare those manual, it was done by checking which tests are indicated and the minimum frequency which they should be conducted in accordance with each manufacturer. The tests were performed by different methodologies and the results were compared. The examined tests were: the breast entrance skin dose, mean glandular dose, contrast-to-noise ratio, signal-to-noise ratio, automatic exposure control and automatic control of density, modulation transfer function, equipment resolution, homogeneity and ghost

Testes de Controle de Qualidade em Sistema de Processamento Computadorizado FUJI

Computed Radiography (CR) is a term used to describe the system that electronically records a radiographic image. CR systems use receivers or IP (imaging plate) to capture the analog signals and then allow the readers to do the image processing and converted into digital information. With the increasing expansion of the CR for medical diagnostics it is necessary that these systems receive the same type of monitoring related to Quality Control and Acceptance to the conventional processing systems. The current legislation fails to specify the parameters and procedures to be tested, allowing that somehow, some equipment is not fully able to use in clinical routine. In this project we used the standard AAPM Report Number 93, which is already fully established outside the country and displays all test parameters in CR. From there were chosen three types of tests that were performed in a satisfactory sampling of IP´s. With this procedure it was possible to establish which of those IP's should be out of use, which reveals the important purpose of the study, demonstrating the need for Quality Control Testing and Acceptance in Computerized Radiography as soon as possible are included in the legislation regulator in the country

Desenvolvimento e controle de qualidade físico e microbiológico de emulsão O/A contendo óleo essencial de Melaleuca alternifolia

Sabe-se que na atualidade, é grande a preocupação da comunidade científica mundial, em relação à resistência microbiana frente às substâncias convencionais, utilizadas indiscriminadamente, por isso, é crescente a motivação da pesquisa básica na bioprospecção de novas substâncias, que apresentem atividade antimicrobiana e antifúngica e que possam ser uma alternativa segura e eficaz contra esses microorganismos no tratamento das doenças causadas por eles. As dermatofitoses, por exemplo, são processos infecciosos de pele, pêlo e unhas que acometem muitas pessoas, de todas as faixas etárias, no mundo todo, provocando as chamadas tinhas ou tineas, denominadas corporis, pedis, cruris, capitis, unguium(onicomicose) e outras (dependendo o local do corpo onde estão), causadas pelo dermatófito filamentoso, Trichophyton rubrum. Estudos envolvendo este patógeno são cada vez mais importantes, devido ao aparecimento de linhagens resistentes aos medicamentos antifúngicos disponíveis no mercado, e ao comportamento invasivo deste agente em pacientes com o sistema imune comprometido. Porém, somente a descoberta de novas drogas não é suficiente, é preciso desenvolver produtos eficazes e seguros, que possam veicular essas substâncias sem causar prejuízo ao paciente. Sendo assim, a proposta desse trabalho é desenvolver uma emulsão A/O, contendo óleo essencial de Melaleuca alternifolia (TTO), verificar sua estabilidade preliminar e caracterizá-la realizando o estudo reológico da formulação, determinar a concentração inibitória mínima (CIM) e a concentração fungicida mínima (CFM) do TTO e averiguar a atividade antifúngica in vitro da emulsão frente ao T. rubrum, agente patogênico ao qual se destina o uso do produto

Controle de qualidade e qualificação de fornecedores de matérias primas utilizadas em uma farmácia de manipulação

Este trabalho apresenta uma proposta de qualificação de fornecedores de matérias primas para uma farmácia na cidade de Araraquara, estado de São Paulo. A qualificação de fornecedores é um processo de extrema importância no que diz respeito ao produto acabado e, para que tenha qualidade, essa qualidade deve vir desde as matérias primas que o compõem. A RDC nº 67 de 8 de outubro de 2007 diz que as farmácias devem adquirir matérias primas apenas de fornecedores qualificados. Para o processo de qualificação, a mesma RDC diz que devem ser feitas auditorias e levantamentos de dados dos fornecedores, bem como o controle de qualidade das matérias primas fornecidas. Foram escolhidas quatro matérias primas utilizadas pela farmácia de três fornecedores diferentes. O processo começou com o envio de questionários avaliativos, onde cada fornecedor deveria colocar as informações solicitadas. O passo seguinte é o controle de qualidade das matérias primas. A partir dos dados dos questionários e dos resultados do controle de qualidade, acrescidos de outros fatores como prazo de entrega, compõe-se o Índice de Qualificação do Fornecedor (IQF), que é como uma “nota” que o fornecedor recebe e, através desse índice, pode ser DESQUALIFICADO, QUALIFICADO ou ainda CERTIFICADO. A certificação ocorre após a auditoria do estabelecimento do fornecedor e também entra na composição do IQF. Após o processo de qualificação dos três fornecedores, foi elaborado um Procedimento Operacional Padrão (POP) com todas as etapas que devem ser feitas para a qualificação...

Modelagem computacional das túnicas cardíacas para processamento e controle de qualidade

This paper considers a study of the anatomical features of the cardiac system and a three-dimensional model of the different tunics that comprise the heart wall, for processing and quality control of radiological images. The structures are built by the layer overlapping method, where a layer can be understood as a slice of the three-dimensional object. The pericardium, myocardium and endocardium were represented with three-dimensional cylinders and hexagons. The spatial arrangement of the cardiac system is determined by an background image of a real model, which values are defined according to the shape of the region and on the anatomical patients characteristics. The results are significant, considering the anatomical structures details, as well as the representation of the thicknesses of the regions of the heart wall. The validation of the anatomical model was accomplished through comparisons with dimensions obtained from a real model and allows verifying that the model is appropriate. The degree of representation will allow the verification of the influence of radiological parameters, morphometric peculiarities and stage of the diseases on the quality of the images, as well as on the performance of the Computer-Aided Diagnosis (CAD).

Parâmetros assistenciais em saúde bucal: comparação entre duas programações do atendimento clínico no serviço público

Objective: To compare two forms of scheduling clinical dental care for the oral health teams (OHT) included in the strategy of family health, regarding productive aspects of assistance. Methods: Two OHT worked concurrently, using two methods of clinical care: the parameter recommended by the Ministry of Health Ordinance No. 1101, 2002, which establishes 03 dental visits per hour (c/h) per team, and a Testing model, with 02 c/h, being each method applied for a period of 615 hours. The quantitative data was collected in OHTs’ daily production spreadsheets, covering the following items: the number of dental visits (initial, for maintenance and for emergency procedures), procedures performed, consumption of material and sterilization cycles. Data was compared and statistically analyzed through the BioStat 5.0 by applying the paired t-test (p <0.05). Results: Under the Ministerial method and the Testing model, were performed, respectively, 288 and 365 first dental visits, 921 and 686 return dental visits, 167 and 172 emergency dental attendances, with 469 and 110 fouls, 212 and 327 treatments were finished and 2501 and 3046 dental procedures were realized. Among eleven analyzed consumables, five were consumed in smaller quantities in the Testing model: gloves (9%), anesthesia (38%), anesthetic needle (34%), suture material (24%) and aspirators (11%), while the six remaining items presented similar consumption rates between the two models. Conclusions: The testing model revealed to be more productive and economical.
