Study Notes
Pneumonia and Lung Abscess
- Pneumonia: Inflammation of lung tissue
- Bacterial: Lobar pneumonia, bronchopneumonia
- Viral/Atypical: Primary atypical pneumonia (confined to alveolar septa without intra-alveolar exudate), often caused by viruses (influenza, parainfluenza, measles, chicken pox, small pox), Mycoplasma pneumonia, Loeffler's pneumonia (associated with eosinophilia, parasitic infestations e.g., ascaris, ankylostoma, Bi Iharziasis)), Granuloma (TB, sarcoidosis, leprosy, actinomycosis)
Lobar Pneumonia
- Definition: Acute serofibrinous inflammation involving at least an entire lobe of the lung, caused by Streptococcus pneumoniae in 95% of cases.
- Cause: Streptococcus pneumoniae
- Mechanism of Infection (MOI): Inhalation (droplet infection)
- Pathogenesis:
- Pneumococci reach alveoli.
- Inflammatory reaction with excess fluid exudate (rich in fibrin) filling the alveoli.
- Fluid exudate spreads through alveolar pores, involving the whole lobe and bacteria reaching the pleura.
- Fluid and cellular exudate displace air from alveoli, leading to consolidation (hepatization) of the affected lobe.
- Stages of Lobar Pneumonia: Red hepatization, Gray hepatization, Resolution
Bronchopneumonia
- Definition: Acute suppurative inflammation of bronchioles and surrounding alveoli, typically with patchy consolidation, due to bacterial infection (S. aureus, S. pyogenes).
- Cause: Various bacterial organisms
- Mechanism of Infection (MOI): Inhalation (droplet infection)
- Types: Primary (due to exogenous invaders) and Secondary (complicates other infections like influenza)
- Post-infective: Complicates respiratory tract infection
- Inhalation: Infected material inhaled
- Hypostatic: Complicates pulmonary edema (heart failure)
- Terminal: Complicates severe diseases (cancer, coma)
- Symptoms: Productive cough, purulent sputum, dyspnea, rigors, pleuritic pain
- High Risk Population: Infants, children, elderly
Lung Abscess
- Definition: Localized suppurative inflammation in the lung due to pyogenic organisms.
- Causes/Types:
- Inhalation (Aspiration) abscess
- Pyaemic abscess
- Post-pneumonic abscess (complicating lobar/bronchopneumonia)
- Secondary infected lung lesions
- Inhalation Lung Abscess: More common, caused by inhalation of infected material, typically affecting one lung lobe (right lung more frequently). Often associated with serofibrinous pleurisy.
- Pyaemic Lung Abscess: Less common, originating in blood vessels, affecting both lungs, no associated bronchus, rapid progression.
- Site: Inhalation: Right lung, upper/lower lobes equally affected, associated with peripheral bronchus; Pyaemic: multi-lobar, not associated with specific bronchus
Complications and Clinical Courses
- Lobar Pneumonia:
- Common resolution
- Rare complications (e.g., fibrosis).
- Clinical course: 7-9 days, ending with a crisis (sudden improvement)
- Bronchopneumonia:
- Rare resolution; common complications (e.g., fibrosis)
- Clinical course: 2-3 weeks, typically terminating with severe complications (or death)
- Both: Spread of infection possible through direct, lymphatic, and blood (bacterialemia). Additional common complications: pericarditis, mediastinitis, osteomyelitis (chest wall bones), meningitis, arthritis, bacteremia, septicemia, and toxic myocarditis.
Differences between Lobar and Bronchopneumonia
| Feature | Lobar Pneumonia | Bronchopneumonia |
|---|---|---|
| Etiology | Acute serofibrinous inflammation, Pneumococci 95% | Acute suppurative inflammation, Staph, Strept, H. influenzae; Primary/Secondary infections |
| Organism | Pneumococci (95%) | Variety of bacteria |
| Route | Primary exogenous infection; 4 stages; Diffuse lesion not related to bronchiole; No pus on pressure; Fibrinous pleurisy is marked | 1st and 2nd infection; No stages; Patchy lesions related to bronchiole; Pus exudates on pressure; Absent pleurisy |
| N/E | Diffuse lesion, no pus, prominent fibrinous pleurisy | Patchy, surrounds bronchioles; Pus cells, RBCs, macrophages; Bronchiolitis occurs |
| M/E | Alveolar spaces contain fibrin, neutrophils, RBCs & macrophages. No bronchiolitis; Pleurisy | Alveolar spaces contain pus, macrophages, and bronchiolitis |
| Fate | Resolution is common; fibrosis is rare | Resolution is rare; fibrosis is common |
| Course | 7-9 days; Ends by crisis | 2-3 weeks; Ends by lysis |
