Exam 2 part 1 Flashcards
What are the characteristics of each COPD?
- Emphysema?
- Chronic bronchitis?
- Bronchial asthma?
- Chronic bronchitis?
- Blebs & bullae, pink puffers
- Blue bloaters
- Grossly hyperaerated lungs touching in midline, mucus production microscopically similar to bronchitis
- Marked mucus production, right heart failure*
What is the definition of chronic bronchitis?
Production of mucus for certain periods of time - a minimum of 3 months a year for at least 2 years
Where would you find things like Blebs and bullae, curschmann’s spirals? - Which COPD disease would you find these?
- Blebs and Bullae: Emphysema
- Curschmann spirals: bronchial asthma
What are the characteristics of Alpha-1-Antitrypsin Deficiency?
- Autosomal recessive
- Anti protease produced by the liver in order to neutralize naturally occuring proteases
- Causes emphysema
What produces naturally occuring proteases?
- Macrophages
- Bacteria
- Neutrophils
- Monocytes
Alpha-1-Antitrypsin does not - it’s from the liver
What is the association of COPD and poor oral health related to lung infections and cigarette smoking?
- Perio disease is a possible risk factor for COPD
- Onset and progression of COPD is dependent on smoking in almost all cases and repeated bacterial infections can worsen the lung disease.
- Perio bacteria could travel to lungs through saliva or normal breathing -> infection
- Inflammation caused by perio may contribute to inflammation in lining of bronchial tubes, leading to chronic bronchitis
- Streptococcus & actinomyces, may modify oropharygneal mucosa to promote growth of Pneumococcus (Gram+) and H. influenzae (Gram-)
What is the genus and species of Legionnaires disease? What’s it’s association with water?
- Legionella pneumophilia
- Gram -
What organism causes Pneumonia and abscesses?
Staphylococcal aureus
What organism causes rust colored sputum?
Streptococcus pneumonia
What organism causes jelly sputum?
Klebsiella pneumoniae
What are the different routes that someone can acquire pneumonia?
- Inhalation of air droplets (most typical)
- Aspiration of upper respiratory infections (staph/strep infections)
- Aspiration of infected gastric particles (anaerobic bacteria)
- Hematogenous spread (blood transfer - common in sepsis, UTI’s or GI tract infection)
Define the different complications of pneumonia:
- Pleuritis
- Pyothorax
- Empynema
- Abscess
- Chronic lung disease
- Extension of inflammation to pleural surface
- Pus fills pleural cavity
- Pus is encapsulated by fibrous tissues into pockets
- Associated with staph and causes destruction of lung parenchyma and suppuration
- Due to unresponsiveness to treatment - transforms lung into honeycomb-like structure
Differentiate intra-alveolar pneuomia vs interstitial pneumonia. And which one is more viral or bacterial?
- Intra-alveolar - bacterial
- Interstitial - involves the alveolar septae which includes viral pneumonia
What are the 2 types of intra-alveolar pneumonia?
- Patchy (broncho pneumonia)
- Diffuse (lobar pneumonia)
What are the general features of tuberculosis?
- Rod-shaped bacterium with waxy capsule
- Acid-fast - neither gram - or +
- Does not stain with dyes
- Obligate aerobe
- Cell wall contains mycolic acid (a complex lipid that in antiphagocytic)
