ABSTRACT
Lung abscess is not an uncommon problem in children. Most isolation include both aerobic and anaerobic flora. However, Staphylococcus aureusis the most common organism found. Staphylococcus aureus produces toxins and enzymes that form the basis of the lesions produced by this pathogen: a pyogenic exudate or an abscess. Pseudomonas is usually the first pathogen isolated in children younger than one year of age with cystic fibrosis, and over 80% are infected with this organism by 18 years of age. Cystic fibrosis is characterised by thick, inspissated mucus, chronic upper and lower respiratory tract infection, and inflammation of the airway. The clinical signs and symptoms of cystic fibrosis can vary widely. Patients may be relatively asymptomatic, present with chronic illness and failure to thrive, or complain of acute, recurrent exacerbations of pulmonary disease. Paediatric surgeons may be involved in the care of these patients in several ways, especially when they present with severe pulmonary complications.
