Diseases of the respiratory system: Bronchiectasis and cystic fibrosis.

Bronchiectasis is characterised by dilatation of the bronchi. This dilation may be 
generalised or confined to a single segment or lobe of the 
lung, and it may be tubular, fusiform (spindle shaped), or saccular 
(cystic). The aetiology, symptoms, diagnosis, treatment, complications, and prevention of bronchiectasis 
are considered. Cystic fibrosis affects many exocrine glands throughout the body. 
Presentation and diagnosis, treatment, complications and their treatment, management of associated 
social problems, and death due to cystic fibrosis are discussed.
