Associação do tiabendazol com mebendazol no tratamento das helmintoses intestinais

420 patients were treated with a combination of mebendazol (5ml or one tablet equaling 100mg) and thiabendazole (various doses) given twice a day for two to three days. The following indexes of cure were obtained. Approximately 90-95% for Enterobius, Strongyloides, Tricocephalus and Ascaris and between 80-90% for hookworm. These results were in hospitalised patients with a control of cure of four examinations in a month. In outpatients the indices of cure declined related to the degree of vigilance observed in relation to drug taking. Then the dose of thiabendazole is raised to 166mg-250mg in 5ml or 500mg in a tablet the duration of treatment can be reduced to three or two days. However more side effects are observed with this regimen.

Terapia da fala no Serviço Nacional de Saúde : avaliação das necessidades de recursos humanos

RESUMO - O planeamento dos recursos humanos em saúde é um assunto relevante na formulação de políticas, face às importantes alterações nos cuidados e necessidades, características demográficas e socioeconómicas. Este planeamento consiste na estimativa do número de profissionais necessários para se atingir determinados objetivos, existindo diferentes métodos para a sua realização. Segundo a Direção Geral de Saúde considera-se adequado um Terapeuta da Fala para 60.000 habitantes – valores calculados através de estudos de prevalência de doença. Porém, o número de recursos humanos encontra-se intimamente ligado à produtividade, determinada através de unidades de medida como os procedimentos. Nesta área, fatores como a complexidade dos doentes e trabalho indireto, podem influenciar o produto final. Neste estudo pretende-se averiguar a necessidade de recursos humanos em Terapia da Fala, analisando a atividade destes serviços nos hospitais da região de Lisboa e Vale do Tejo e aplicando a fórmula de preconização proposta pelo Ministério da Saúde, baseada num modelo de oferta. Participaram no estudo 23 Terapeutas da Fala de 9 instituições hospitalares. Foi construída uma folha de registo do trabalho diário, preenchida durante cinco dias não consecutivos, averiguando-se assim o tempo gasto nas diferentes atividades. Verificou-se que 63,21% do horário laboral é utilizado na concretização de atos diretos e 36,76% gasto em atos indiretos, relacionados com os utentes, não contabilizados na fórmula proposta. Incluindo as diferentes componentes (atos diretos e indiretos), constata-se que o número de profissionais existentes na região de Lisboa e Vale do Tejo é adequado, embora numa análise por instituição o resultado seja contraditório.

Analysis of the use of fenthion via epicutaneous in dogs for Rhipicephalus sanguineus control

The action of fenthion was studied in a 15% epicutaneous formulation upon Rhipicephalus sanguineus, which may transmit pathogens to men and other animals, such as Ehrlichia, Babesia and Ricketsia. Dogs were artificially infected for the trial. The fenthion bioassays were begun four months after artificial infestation. The test group, having a mean of 186 ticks per dog, received the formulation dosage according to body weight on the neck region. Tick counts were performed, considering diameters > or = 2mm, during 11 days of treatment, in the most affected body areas: back, ears and paws. Before the application of fenthion in the dogs, it were observed an average 43.3% ticks in the ears, 38.1% in the back area and 17.6% in the paws. The number of ticks in dogs decreased by 36.2%, 63.8%, 82.7%, 67%, 40% and 4.9%, respectively on days 1, 2, 3, 5, 7, 9 and 11 after treatment. R. sanguineus anti-tick activity, lower than that officially recommended, was verified. The number of ticks increased progressively after the 5th day, demonstrating residual insecticide inefficacy. The results obtained did not indicate the use of this formulation, at the tested dosage, as an elective measure for R. sanguineus control.

Lime mortars with heat treated clays and ceramic waste: A review

The formulation and use of lime mortars with ceramic particles has, in the past, been a very common technique. Knowledge of such used techniques and materials is fundamental for the successful rehabilitation and conservation of the built heritage. The durability that these mortars have shown encourages the study of the involved mechanisms, so that they may be adapted to the current reality. The considerable amount of waste from old ceramics factories which is sent for disposal might present an opportunity for the production of reliable improved lime mortars. In this paper a number of studies that characterize old building mortars containing ceramic fragments are reviewed. The most important research undertaken on laboratory prepared mortars with several heat treated clays types is presented, specifically with incorporated ceramic waste. Some studies on the pozzolanicity of heat treated clays are examined and the heating temperatures that seem most likely to achieve pozzolanicity are presented. It was verified that some heating temperatures currently used by ceramic industries might correspond to the temperatures that will achieve pozzolanicity.
