Community acquired pneumonia: clinical manifestations.

Pleuritic chest pain is common as it frequently involves peripheral lung and spreads quickly to the pleura. Sputum may be blood-streaked or rusty because capillary leakage of blood into the alveolar space in the phase of red hepatisation. Now a days this is less common findings because of modifying effects of antibiotics on pathological process. The sputum is usually yellowish or greenish in colour, sometimes containing flecks of blood. On physical examination the patient may be sweating, flushed and ill looking. Cyanosis is uncommon in previously healthy patient and when present indicates extensive pneumonia. Fever with concomitant tachycardia is present. Tachypnea is usually present as breathing may be limited in depth by pleuritic pain. An impaired percussion note over the affected lobe may be elicited. The breath sounds are usually tubular bronchial breathing over the same area associated with increased vocal fremitus and vocal resonance, aegophony and whispering pectoriloquy. Localized crepts may be heard. Herpes labialis is usually present within few days of onset of infection. Although the above clinical features are well recognized in relation to lobar pneumonia, in a microbiological sense they are entirely non-specific and it is impossible to conclude with certainty that the infective organism is Strep. pneumonia without supporting evidence from the laboratory. Furthermore, the classical presentation in modern-day practice is often modified by the early use of antibiotic therapy, the presence of pre-existing lower respiratory tract disease such as chronic bronchitis, emphysema and bronchiectasis, and age of the patient. Loss of mental clarity, somnolence or frank confusion are also found commonly in elderly patients with pneumonia of any type, and may be a co-existing manifestation of the pneumonia itself or of deterioration in a coexisting illness such as renal insufficiency or congestive cardiac failure. Symptoms in the young children may be non-specific and misleading. Fever and delirium are common. Respirations may be rapid and grunting. Meningism is sometimes present and abdominal pain may occur in lower lobe pneumonia. The usual ascultatory finding of consolidation may be absent or difficulty to detect, making chest radiograph essential for diagnosis. Leukocytosis is common. Early in the disease, chest x ray findings may be normal, but later, they may show classic lobar pneumonia. Pleurisy or effusion is common, and cavitation is rare. Haemophilus influenzae
