Fração Exalada de Óxido Nítrico no Controlo e Abordagem Terapêutica da Asma

INTRODUCTION: Asthma is a chronic respiratory disease characterized by hyper-responsiveness and bronchial inflammation. The bronchial inflammation in these patients can be monitored by measuring the fractional exhaled nitric oxide. This study aims to determine fractional exhaled nitric oxide association with peak expiratory flow and with asthma control inferred by the Global Initiative for Asthma. MATERIAL AND ...

Síndromes de Falência Medular Hereditários — Seis Casos Clínicos

Os Síndromes de Falência Medular Hereditários são um grupo heterogéneo de doenças, que se caracterizam pela produção reduzida de uma ou mais linhagens hematopoiéticas pela medula óssea e consequentes citopenias no sangue periférico. Associam-se a um variado número de malformações congénitas e a maioria são entidades «pré-malignas».A propósito de seis casos, os autores tecem algumas considerações sobre as caract...

Caso radiológico: pneumomediastino e enfisema subcutâneo secundário a asma

ABSTRACT We present the case of a 5 year old asmathic girl admitted to the hospital for acute non traumatic edema and crepitus of the face, neck and upper thorax. Thoracic x-ray (not shown) and thoracic and neck CT were performed, showing extensive subcutaneous and mediastinal enfisema. These are rare complications of asthma. The imaging features are described.

Behaviour of human erythrocyte aggregation in presence of autologous lipoproteins

The aim of this work was to evaluate in vitro the effect of autologous plasma lipoprotein subfractions on erythrocyte tendency to aggregate. Aliquots of human blood samples were enriched or not (control) with their own HDL-C, LDL-C, or VLDL-C fractions obtained from the same batch by density gradient ultracentrifugation. Plasma osmolality and erythrocyte aggregation index (EAI) were determined. Blood aliquots e...

Total body percentage and motor coordination among Portuguese schoolchildren

Children’s motor coordination may affect their activity pattern and thereby influence their bodyfatness. The aim of the present study was to analyse the relationship between motor coordination and total body fat percentage, in a Portuguese sample of schoolchildren aged 9–12 years. Method: The sample comprised 596 urban schoolchildren (girls 46?9%), aged 9–12 years (mean 9?61 ( SD 0?55) years) from North of Portu...
