    I've posted this on DNUK but I'm scared of that place so I'm posting it here too...:p: This is from one of the popular online question banks.

    Lung Diseases Associated with Cough

    A Bronchial asthma
    B Bronchiectasis
    C Croup
    D Cystic fibrosis
    E Emphysema
    F Fibrosing alveolitis
    G Legionnaire’s disease
    H Mycoplasma pneumonia
    I Pertussis (whooping cough)
    J Pneumococcal pneumonia
    K Sarcoidosis
    L Tuberculosis

    For each of the results below, select the disease most likely to account for them from the above list.

    Question:
    Mucoid Pseudomonas aeruginosa isolated from sputum.

    Model Answer:
    D Cystic fibrosis

    "Pulmonary infection is a major and recurrent problem in patients with cystic fibrosis. In early childhood, infections with Staphylococcus aureus predominate but with repeated courses of antibiotic therapy, subsequent infections with multiple antibiotic resistant organisms develop. These latter organisms include Pseudomonas aeruginosa, often 'mucoid' strains."
    My question is this: why can't this be bronchiectasis for the same reason given above? I was under the impression that the recurrent infections in CF leads to a bronchiectatic picture, and have also come across patients with bronchiectasis with P. aeruginosa in their sputum culture. I've discussed this with a couple of friends and we haven't really got anywhere...

    What am I missing here?:confused:
