A Distrofia Simpática Reflexa é rara em pediatria. É uma síndrome complexa de dor regional, de causa desconhecida, geralmente pós-traumática, com disfunção músculo-esquelética, vascular e da pele: dor intensa persistente de um membro associada a alterações vasculares e sensoriais, incapacidade física e disfunção psico-social. O diagnóstico é essencialmente clínico, baseado num alto índice de suspeita. Na crianç...
Introdução: O cancro da próstata é uma importante causa de morbilidade e mortalidade. Em Portugal, de acordo com um estudo publicado em 2003, a taxa de novos casos de cancro na próstata era de 53 por 100.000 homens, em 2000, com uma taxa de mortalidade padronizada pela idade de 28 por 100.000 (em 1995). As metástases ósseas múltiplas são uma das principais complicações associadas ao cancro de próstata avançado....
Technetium-99m tetrofosmin (Myoview) has unique properties for myocardial perfusion imaging very early after injection of the tracer. We used a very short same-day rest/stress protocol, to be performed within 2 h and evaluated its diagnostic accuracy. The study included 144 patients from seven Spanish and four Portuguese centres with a diagnosis of uncomplicated coronary artery disease (CAD); 78 patients (54%) ...
Fifty five patients with previous myocardial infarction (MI), 47 male and 8 female, mean age 55.5 +/- 8.9 years, have been studied in order to correlate the alterations found on the equilibrium (gated) radionuclide angiogram (RNA) with the location of the MI on the electrocardiogram of the obstructive lesions on coronary angiographies. Of the 55 patients studied, 22% showed no regional wall motion abnormalities...
Controversy remains in considering non-Q wave myocardial infarction (NQMI) a distinct pathophysiological entity of Q wave myocardial infarction (QMI). In order to analyze the severity of coronary artery disease, extension of myocardial scar or myocardial ischemia and ventricular function, 78 consecutive patients with QMI and 32 with NQMI, mean age 55.4 +/- 8.5, not submitted to thrombolytic therapy, were studie...
In 52 patients with previous myocardial infraction, 49 men and 3 women (mean age 56 +/- 7.1 years) the significance of ST-segment elevation during the stress-test, was evaluated. Of the 52 patients 15 (29%) showed St-segment elevation and 37(71%), showed no alteration of the ST-segment. Extension of coronary disease, degree of obstruction, wall motion abnormalities and the presence of residual ischemia were eva...
