Résumé

The relevance of the relationship between cardiac disease and depressive symptoms is well established. White matter hyperintensity, a bright signal area in the brain on T2-weighted magnetic resonance imaging scans, has been separately associated with cardiovascular risk factors, cardiac disease and late-life depression. However, no study has directly investigated the association between heart failure, major depressive symptoms and the presence of hyperintensities. Using a visual assessment scale, we have investigated the frequency and severity of white matter hyperintensities identified by magnetic resonance imaging in eight patients with late-life depression and heart failure, ten patients with heart failure without depression, and fourteen healthy elderly volunteers. Since the frontal lobe has been the proposed site for the preferential location of white matter hyperintensities in patients with late-life depression, we focused our investigation specifically on this brain region. Although there were no significant group differences in white matter hyperintensities in the frontal region, a significant direct correlation emerged between the severity of frontal periventricular white matter hyperintensity and scores on the Hamilton scale for depression in the group with heart failure and depression (P = 0.016, controlled for the confounding influence of age). There were no significant findings in any other areas of the brain. This pattern of results adds support to a relationship between cardiovascular risk factors and depressive symptoms, and provides preliminary evidence that the presence of white matter hyperintensities specifically in frontal regions may contribute to the severity of depressive symptoms in cardiac disease.

Résumé

A fonoforese e um sistema de aplicacao de drogas atraves da pele que utiliza o ultra-som para aumentar a eficacia da penetracao. Embora atualmente seja modalidade bastante empregada na pratica fisioterapeutica, poucos produtos tem apresentado caracteristicas apropriadas para o uso. O proposito do presente estudo foi avaliar a transmissibilidade dos medicamentos mais utilizados nas clinicas de fisioterapia, por meio de analises qualitativas e quantitativas. A analise qualitativa foi realizada por meio da observacao da movimentacao de ondas ultra-sonicas na superficie de uma camada de agua, enquanto a analise quantitativa foi feita com o auxilio de uma balanca semi analitica. Foi constatada uma pratica de 65 (por cento) da fonoforese nas clinicas avaliadas, sendo que os modos continuo e pulsatil sao aplicados em iguais proporcoes. Na analise qualitativa, o gelol, o Inflamene creme e o Iodex pomada foram reprovados. Ja na analise quantitativa, o Proflam creme e o Clofenak gel demonstraram transmissibilidade pobre, Calminex pomada, transmissao moderada e os demais medicamentos, 8 no total, mostraram boa transmissibilidade. Os dados finais demontraram que, dos 14 medicamentos avaliados, 8 revelaram-se adequados para o uso da fonoforese, e entre esses estao os mais utilizados pelos fisioterapeutas na pratica da fonoforese
