Avaliação da qualidade química e microbiológica de tintas didácticas do ensino ...

As tintas utilizadas nas actividades didácticas possuem na sua composição ingredientes que dada a sua natureza, modo de fabrico e de utilização, podem representar um risco para a saúde das crianças. Neste âmbito, procurou-se com este estudo avaliar a qualidade química e microbiológica das tintas utilizadas pelas crianças no ensino pré-escolar. Vinte e nove amostras de tintas, incluindo guaches, tintas de águas,...

Síndrome Coronária Aguda sem elevação do segmento ST: duração do QRS e prognóst...

BACKGROUND: Recent studies have demonstrated that QRS duration (QRSd) is associated with poor prognosis in heart failure and ST-elevation myocardial infarction. Less is known about the prognostic importance of QRSd in patients with non-ST elevation acute coronary syndrome (non-ST ACS). AIM: To determine if admission QRSd is associated with 1-year mortality in non-ST ACS. METHODS: We studied 539 patients (aged 6...

Impacto da fibrilhação auricular nas síndromes coronárias agudas

INTRODUCTION: Atrial fibrillation (AF) is a relatively common arrhythmia in the context of acute coronary syndromes (ACS). However, the impact of AF on these patients' survival is not well established. The present study aimed to estimate the prevalence of AF in ACS patients and to evaluate its impact on in-hospital and six-month post-event mortality, from any cause. METHODS: This was a retrospective cohort stud...

Toxicidade cardiovascular da cocaína de natureza iatrogénica: caso clínico

The use of cocaine as an illicit drug is associated with various cardiovascular events. In recent decades, because of growing levels of consumption, there has been an increasing incidence of these complications. At the same time, cocaine is also widely used as a local anesthetic, mainly in nasal surgery. Its application in this context is controversial due to the potential associated adverse effects. The author...

Sudden death and variant angina

Variant angina is defined by chest pain occurring at rest associated with transitory ST segment elevation on ECG, and is caused by a spasm of a coronary artery. Frequently, variant angina is associated with atherosclerotic coronary obstruction and patients with normal coronary arteries are rare. Patients with variant angina and normal coronary arteries have good prognosis, and the development of ventricular arr...
