Information and education in schistosomiasis control: an analysis of the situation in the State of Minas Gerais, Brazil.

This paper presents the main ideas discussed in the round-table "Social and Educational Aspects of Schistosomiasis Control", during the VII International Symposium of Schistosomiasis. Considering the perspectives of schistosomiasis control in Brazil, it is described the example of the State of Minas Gerais, where the disease has been registered for more than seven decades. The importance of an extensive evaluation is now more important, considering the recent change in the Brazilian health system, since the Federal responsibility for the tropical diseases control programs have been replaced by the municipalities coordination. In this way, it is urgent to develop effective alternatives to assist the municipal staffs in the control task. In the specific case of health education, one observes a wide gap between the planned objectives and what is in fact carried out. Instant objectives and the utilization of traditional techniques prevail, which do not take into account the active participation of the population involved. Based on the authors' experience in the scientific and health education, the paper analyzes: (1) some data from a case study in the metropolitan region of Belo Horizonte, which presents the social representation and perception of schistosomiasis by the population; (2) an analysis of 35 different informative and educative materials used in Brazil since the sixties, and (3) some recommendations resulted from the studies that were carried out.

Avaliaçäo dos vasos, da agregaçäo plaquetária e do mecanismo da anticoagulaçäo natural nas doenças coronarianas / Vessels, platelet aggregation and natural anticoagulation mechanism evaluations in coronarian diseases

Este trabalho teve como objetivo investigar a presença de lesäo e seu efeito sobre a competência funcional do mecanismo da anticoagulaçäo natural. Foram analizadas 45 amostras de sangue de pacientes com angina de peito (n=11), indivíduos com alto risco para desenvolverem essas doenças, porém, assintomáticos (n=16) e de indivíduos sadios empregados como controle (n=10). Foram realizadas a avaliaçäo de trombomodulina (marcador de lesäo endotelial), da agregaçäo plaquetária, do fibrinogênio, do fator VIII e da proteína C, essa envolvida no sistema da anticoagulaçäo natural. Os níveis de trombomodulina, fator VIII e fibrinogênio se mostraram elevados nos pacientes com infarto e angina, ao contrário da proteína C, que se mostrou diminuída nesses pacientes, quando comparados ao controle. Diferenças entre os grupos controle e de risco foram observadas apenas para o teste da agregaçäo plaquetária, cujos resultados foram similares para os grupos de risco, angina e infarto, sugerindo que este teste pode ser utilizado como um parâmetro preditivo de risco para doença coronariana. Uma interpretaçäo dos resultados permite estabelecer a ocorrência de lesäo endotelial e sua consequência sobre a competência funcional do sistema da anticoagulaçäo em pacientes com tais doenças, resultando em um desequilíbrio entre procoagulantes e anticoagulantes, o que favorece a formaçäo de trombo.

[Acute neurogenic pulmonary edema: a case report]. / Edema pulmonar agudo neurogênico: relato de caso.

The authors report a case of acute neurogenic pulmonary edema in a 28-year-old woman who presented rupture of an internal carotid artery aneurysm and subarachnoid hemorrhage. The respiratory disorders started at the same time the patient's symptomatology aggravated. Some etiological and pathophysiological aspects on neurogenic pulmonary edema are revised.

Persistent atrial standstill with limb girdle muscular dystrophy.

A case of persistent atrial standstill associated with muscular dystrophy of the limb girdle type is reported for the first time in the literature, In spite, of advanced myopathy, the patient delivered an apparently normal child. Hemodynamic studies including a normal coronary cinearteriography were performed in the post-partum period. The patient also had clinical and radiological evidence of peptic ulcer which may be the expression of an excessive vagal tone. A congenitial anomaly of the conduction system might explain the association of left anterior hemiblock with persistent atrial standstill, but could not be demonstrated.
