How Were Conflicts of Interest Handled?

Conflicts of interest were potentially great but they were minimized by the great conviction from both Doctors and Health Ministry that something had to be done to improve data on perinatal health. To decrease the number of hospitals where deliveries took place, to concentrate doctors, nurses and equipment, to define staff and to acquire equipment and to train nurses and paediatricians was the way. One the point of view of cost-effectiveness, centralization of expensive technologies, and development of expertise concentrating cases in a same centre - Surgery, VLBW, etc- and lowering mortality rates and get better outcomes were clear health gains. In 1989 after the political decision of closing small maternities the committee return to villages and cities to explain to political local power and people, the decision, which kind of care they will have in the future, why and expected gains. Level I hospitals and Health Centers stop to have deliveries; Health Centers were given a great responsibility: the follow up of the most part of the normal pregnancies by GP. There was no economic pressure because the National Health Service is free, there are no economic incentives for obstetrical or neonatal care, hospitals are financed through ICD, hospital level is defined according to both delivery and newborn care. In 1989 the rule was “No results can be obtained without the interested and responsible participation of all – institutions and people”. At that time the emphasis was on training. There are geographic influences on regionalization for example for islands and inner and far geographic areas. Also we would like to emphasize the influence of demographics on regionalization. As birth rate continues to decrease the hospitals left open 20 years ago with more than 1500 deliveries have to be closed now because the number of deliveries decreased. It was much more difficult and unacceptable to close some few maternities now than 20 years ago. All the difference was that at that time reasons were explained and now it was a Minister order. Other fearful events are the opening of private hospitals, the lowering gross national income, the economic difficulties and financial problems.

Efeito Conjunto da Exposição à Poluição do Ar e aos Ácaros do Pó Sobre as Vias Aéreas

Introdução: A asma é uma doença respiratória crónica, cujo agravamento pode estar associado a factores ambientais, entre os quais os relacionados com a qualidade do ar. Objectivo: O presente trabalho pretendeu avaliar o efeito da exposição individual a poluentes atmosféricos em termos de função respiratória, num grupo de crianças com história de sibilância, entrando em consideração com o grau de infestação de ácaros do pó doméstico. Métodos: Um grupo de 51 crianças com história de sibilância, seleccionadas através do questionário do estudo ISAAC, foi acompanhado prospectivamente num estudo com medidas repetidas, que envolveu avaliações médicas padronizadas que incluíram a realização de espirometria, avaliação da exposição aos ácaros do pó e cálculo do valor de exposição individual a uma variedade de poluentes do ar: PM10, O3, NO2, benzeno, tolueno, xileno, etilbenzeno e formaldeído. Resultados: Observou -se uma elevada percentagem de colchões com um grau de infestação de ácaros médio ou elevado. Com excepção dos valores de PM10, os valores de exposição aos poluentes do ar não alcançaram valores elevados. Na análise multivariável, tanto os poluentes (designadamente PM10, NO2, benzeno, tolueno e etilbenzeno) como o grau de infestação de ácaros do pó associaram -se a deterioração da função pulmonar. Conclusão: O presente trabalho vem reforçar o interesse da exposição aos poluentes do ar em crianças com história de sibilância, que à semelhança do que acontece com os ácaros do pó influenciam as vias aéreas.
