An attempt to control schistosomiasis mansoni in an endemic area by the use of Hycanthone as chemotherapeutic agent

Hycanthone in a single dose of 3.3 mg/kg of body weight was used to treal mansoni schistosomiasis in 597 persons (83%) of the population of the endemic vilage of Canabrava. Ninety two patients received a 2nd course 14 months later. There was one death em the 2nd treatment. The cure rate after one stool examination was smaller after the 2ni treatment in comparison with the first one. Re-infections did not occur imediately after the treatment. Three years later the prevalence of persons passing eggs through one stool examination was 19% compared to the 46.3% before the treatment. Adults are more resistant to the re-infections than younger.

The control of Chagas' disease transmission in Mambaí, Goiás-Brazil (1980-1981)

BHC application in Mambai in 1980 resulted in a significant decline but not elimination of domiciliated T. infestans. T. sordida peridomestic populations persist and could pose a threat to interupting human transmission of T. cruzi The results of one massive attack spray application alone was compared with this application plus one selective application as regards the presence of T. infestans in houses oneyear later. No significance difference could be detected. It is likely that for interruption of T. infestans transmission cheaper procedures can be devised than those currently in use. A further pilot study of a virgin community afflicted by T. infestans transmission is indicated since Mambai cannot be regarded as a representative areafor those still awaiting insecticide application.

Controlo de qualidade interno: elaboração de um programa de Controlo de Qualidade Interno segundo as boas práticas da Qualidade

RESUMO: Esta dissertação pretende apresentar uma proposta para um programa de Controlo de Qualidade interno das hormonas tiroideias, segundo as boas práticas da qualidade. Para que se comprove o rigor e fiabilidade dos seus resultados analíticos, condição indispensável para que estes possam servir de base às mais diversas tomadas de decisão, toda a filosofia que envolve a qualidade assume um papel preponderante. Neste contexto a elaboração de um programa de controlo de qualidade adequado é muito importante e imprescindível. A realização do controlo de qualidade permite monitorizar o desempenho de todos os materiais, equipamentos, instrumentos e métodos analíticos bem como criar sinais de alerta para prevenir a emissão de resultados não-conformes e indicar a necessidade de ações corretivas. Permite também indicar a necessidade de melhorias em processos e em atividades ligadas aos operadores e consciencializar o pessoal de que o controlo da qualidade é um dever para com o cliente e tem a função de gerar confiança nos resultados obtidos. O controlo de qualidade interno abrange todos os procedimentos assumidos por um laboratório para avaliação contínua do seu trabalho. A sua finalidade é assegurar a consistência dos resultados diários e a sua conformidade com critérios definidos, avaliando a precisão dos ensaios e dando indicação do momento para se promoverem ações corretivas quando surge uma não conformidade. Segundo as melhores práticas da qualidade, serão calculados os valores do controlo de qualidade interno para as hormonas tiroideias, os seus limites e critérios (regras) de aceitabilidade, com base na relação entre o desempenho analítico e o Erro Máximo Admissível. Pretende-se assim, otimizar o desempenho do Controlo de Qualidade Interno, aperfeiçoando a capacidade de identificação do erro.-------- ABSTRACT: This paper intends to submit a proposal for a thyroid hormones internal quality Control program, according to the best quality practices. The whole philosophy involving quality plays a central role in order to prove the accuracy and reliability of the analytical results, a basic prerequisite for decision making. In this context the elaboration of an appropriate quality control program is essential and very important. Quality control allows the motorization of the performance of all materials, equipment, instruments and analytical methods, as well as the creation of warning signals indicating the need for corrective actions, to prevent the release of non-compliant results. It also indicates the need for improvements in the processes and operating activities as well as making the staff aware that quality control is a duty to the client and promotes confidence in the results. The internal quality control covers all procedures undertaken by a laboratory for a continuous evaluation of its performance. Its purpose is to ensure the consistency of the daily results and compliance with defined criteria, assessing the accuracy of the tests and indicating the moment to promote corrective actions when nonconformity appears. According to the best quality practices, the values of the internal quality control for the thyroid hormones, their limits and criteria (rules) of acceptability will be calculated, based on the relationship between analytical performance and the maximum allowable error. Thus, the aim is to optimize the performance of the Internal Quality Control, improving the ability for error detection and identification.
