Pneumonia is a lung parenchyma infection caused by bacteria, a virus or fungi, with a consolidation on radiological examination.Pneumonitis is an inflammation of the lungs caused by chemical or radiation therapy but not with infectious agents. Definition
Spread of lung infections • Inhalation • Aspiration of oropharingeal secretion • Hematogenic spread • Direct spread (thorax wall, mediastinum)
Predisposing factors of pneumonia • Airways mechanical barrier damage • Specific and/or nonspecific immune defense mechanisms injury • Bronchial obstruction • Micro aspiration of upper respiratory truck secretion. • Lung edema • Viral infections.
Diagnostic Methods • History, physical examination • Chest X-Ray • Sputum examination (gram stained) • Sputum , blood cultures • Serological tests • Peripheral blood analysis
Diagnosis Symptoms fever, shaking chills, cough, sputum (expectoration), pleuritic pain. Others: (dispnea, fatigue, sweating, loss of appetite...) Physical signs: increased vibration thoracic impaired percussion (matity), end inspiratory rales (crepitations) and bronchial breathing (tuber soufle) Others (cyanosis, tachipnea, tachicardia...)
Diagnosis Radiology: lobar opacities, interstitial images, bronchopneumonic (patchy) opacities, Others (absea, pneumatocele, pleurisy...)
Chest X-Ray • Gold standart test for pneumonia • For differencial diagnosis • For grading pneumonia severity • For examining complications
Normal Chest X Ray in Pneumonia • -First 24 hours • -Dehydration • -Elderly • -Neutropenia • -Pneumocystis carinii
Classification with anatomical localization • Lobar consolidation • Bronchopneumonia • Interstitial pneumonia
Classification with ethiology • Bacterial • Viral • Fungal • Parazites
Classification with targeting therapy • Community acquired pneumonia • Hospital acquired pneumonia (Nosocomial) • Immunosuppresed (immunocompromised) patients pneumonia
Pneumonia acquired outside hospital frequently in healthy persons Community acquired pneumonia
