Document Summary
Airway diseases where infection is a large component bronchiectasis & cf. Infections may cause flare-up of pre-existing disease i. e. acute exacerbations of. Recurrent bronchitis: cough + sputum >2/12, no features of chronic bronchitis, more likely bacterial need antibiotics. Look for underlying sinusitis, post-nasal drip & bronchiectasis: previously well, cough +/- sputum, usually viral, may be complicated by secondary bacterial infection. Typical: pre-existing disease, abrupt onset, purulent sputum, pleuritic pain, marked systemic upset, localised signs, responds to -lactams. Atypical (legionella, mycoplasma & chlamydia psittaci): previously well. Insidious onset: dry cough, sob & wheeze, mild systemic upset, no response to -lactams. Mycoplasma exhibits winter peaks & comes in epidemics spikes every 3yrs. Legionella appears more in sept/oct, 50% related to travel (spain & turkey) & 20% clusters. L upper lobe cavitation tb, staph, klebsiella & ca common causes of cavitation. Lower l lobe pneumonia loss of diaphragm +/- heart border. Middle r lobe loss of r heart border.
