Study Notes
- Pneumonia is an inflammation of the alveoli, commonly caused by bacteria, with classifications based on anatomy (lobar pneumonia, bronchopneumonia) and etiology (bacterial, viral).
- Streptococcus pneumoniae is a common cause of community-acquired acute pneumonia, affecting healthy adults between 20-50 years with lobar pneumonia and older individuals, infants, and those with debilitating diseases with bronchopneumonia.
- Clinical features of pneumonia include respiratory symptoms like cough, purulent sputum, and dyspnea, systemic symptoms such as fever, and signs like consolidation and pleural rub.
- Diagnostic investigations for pneumonia involve chest X-ray, blood cell count (>15x10^9/L in bacterial infections), sputum tests (gram stain, culture, sensitivity), and other specific tests for pathogens like Mycoplasma and Legionella.
- Management strategies for community-acquired pneumonia include immediate antibiotic treatment without waiting for microbial results, while hospital-acquired pneumonia often involves Gram-negative organisms requiring different antibiotics based on culture and sensitivity results.
- Complications of pneumonia may include lung abscess and empyema, highlighting the importance of prompt diagnosis and appropriate treatment to prevent adverse outcomes.
- Tuberculosis, caused mainly by Mycobacterium tuberculosis, remains a significant global health concern as the leading cause of death from a single infectious disease, particularly affecting developing countries but also showing an increasing prevalence in developed nations.
