  1. Diseases of the Respiratory System Pathology Department of SiChuan University Su Xueying

  2. Normal structure of the respiratory tract

  3. The lower respiratory tract

  4. Respiratory mucosa

  5. The respiratory system disease is very common • Emvironmental factors is important

  6. Major aetiological factors in respiratory disease • Emvironmental Smoking Lung cancer Chronic bronchitis and emphysema Susceptibility to infection Air pollution Chronic bronchitis Susceptibility to infection Infection Influenza Pneumonia Tuberculosis Occupation Lung cancer Mesothelioma • Genetic Cystic fibrosis Some asthma

  7. OUTLINE 1.Pulmonary Infections Bacteria Pneumonias Atypical Pneumonias Tuberculosis 2.Chronic Obstractive Lung Diseases (COPD) Emphysema Chronic Bronchitis 3.Bronchiectasis 4.Cor Pulmonale 5.Lung tumors

  8. OUTLINE 1.Pulmonary Infections Bacteria Pneumonias Atypical Pneumonias Tuberculosis 2.Chronic Obstractive Lung Diseases (COPD) Emphysema Chronic Bronchitis 3.Bronchiectasis 4.Cor Pulmonale 5.Lung tumors

  9. Definition Bacteriapneumonia is due to bacteria infection affecting distal airways, especially alveoli, with formation of an inflammatory exudate. often follows a viral upper respiratory tract infection

  10. Streptococcus pneumoniae (pneumococcus) • Staphylococcus • Haemophilus influenzae • Klebsiella pneumoniae • Moraxella catarrhalis

  11. Lobar pneumonia congestion stage red hepatization gray hepatization resolution Bronchopneumonia

  12. Lobar pneumonia • Affects a large part, or the entirety of a lobe, frequently unilateral • Affects otherwise healthy adults between 20 and 50 years of age, males more than females • 90% due to Streptococcus pneumoniae

  13. Stage of congestion Red, edematous

  14. Red hepatization • Red • Solid • Consistency resembling fresh liver

  15. Gray hepatization

  16. Fibrinous pleuralitis

  17. Gray hepatization • Dry • Pale • Firm

  18. Gray hepatization

  19. Resolution stage

  20. Symptoms • High fever • Chills • Chest pain • Mucopurulent cough • with/without hemoptysis (rusty sputum) • Dyspnea

  21. Bronchopneumonia(Lobular pneumonia) • Patchy consolidation • Centred on bronchioles or bronchi • Usually in infancy or old age • Usually secondary to pre-existing disease • Fever, cough

  22. Bronchopneumonia

  23. Bronchopneumonia

  24. Bronchopneumonia

  25. Bronchopneumonia

  26. Outcomesof Pneumonia • Complete recovery • Complications developed Abscess formation Empyema Bacteremic dissemination • Organization

  27. Empyema

  28. Abscess formation

  29. abscess formation

  30. Organization

  31. Diagnosis & Therapy Physical examination X-ray Blood culture Penicillin or other sensitive antibiotic treatment

  32. X-Ray

  33. Diagnosis & Therapy Physical examination X-ray Blood culture Penicillin or other sensitive antibiotic treatment

  34. OUTLINE 1.Pulmonary Infections Bacteria Pneumonias Atypical Pneumonias Tuberculosis 2.Chronic Obstractive Lung Diseases (COPD) Emphysema Chronic Bronchitis 3.Bronchiectasis 4.Cor Pulmonale 5.Lung tumors

  35. Atypical pneumonia • The concept was set forth in 1938 • The clinical course is unlike the “typical” bacteria pneumonia

  36. Causes mycoplasma virus chlamydia

  37. Gross morphology Red, congested Patchy or whole lobes

  38. Microscopic characteristic the inflammatory reaction is largely confined within the walls of the alveoli, the septa are widened and edematous with mononuclear cells infiltration--- interstitial pneumonia
