    Sammanfattning : Introduction: Adrenal tumours can either be benign or malignant, hormone secreting or not, and they can be discovered through clinical examination of the patient or by pure chance. Increased knowledge in the area, plus the widespread use of imaging techniques, have resulted in a rising number of patients with adrenal tumours that subsequently need to be diagnosed.

    Sammanfattning : Staphylococcus aureus is a human commensal colonizing about 30 per cent of the population. Besides, it is a frequent cause of infections such as skin, wound and deep tissue infections and also more life-threatening conditions such as pneumonia, endocarditis and septicaemia. S. aureus may also cause different toxicoses. LÄS MER
