A

Chronic bronchitis

37
Q

With chronic bronchitis.

A combination of beta 2 agonists and anticholinergics is better than either used alone.

40
Q

List the main anticholinergics used with COPD

A

Ipratropium and Tiotropium

41
Q

What do anticholinergics do again with COPD?

A

Decrease acetylcholine mediated bronchoconstriction.

42
Q

Who do you NOT want to give an anticholinergic to?

A

People with glaucoma and/or BPH because it increases urinary retention and causes pupil dilation.

43
Q

List the main beta 2 agonists used with COPD

A

Albuterol, terbutaline, salmeterol (long acting).

44
Q

What drug would you use in refractory cases?

A

Theophylline. But remember what you already learned about his drug.

No. May use with a long acting (like salmeterol + fluticasone).

Q

What are the SE of inhaled corticoids again?

A

Osteoporosis, thrush!!!, hyperglycemia, fluid retention, infection

47
Q

What vaccines should all COPDer’s get?

A

Pneumococcal and influenza

48
Q

What is the only treatment proven to decrease mortality with COPD?

A

O2 baby

49
Q

FEV1 equal to 80% stage and treatment

A

Stage I Mild. Treat with short acting bronchodilators.

50
Q

FEV1 between 30% and 50% stage and treatment

A

Stage III Severe. Short acting bronchodilators + long acting dilator + pulmonary rehab + steroids for increasing exacerbations.

51
Q

FEV1 between 50% and 80% stage and treatment

A

Stage II Moderate. Short acting bronchodilators + long acting dilator

52
Q

FEV1 between less than 30%, cor pulmonale, right heart failure, respiratory failure, stage and treatment

A

Stage IV Very Severe. Short acting bronchodilators + long acting dilator + pulmonary rehab + steroids for increasing exacerbations. + O2

53
Q

You see a CXR with enlarged right heart, normal diaphragm, increase in vascular markings, and prominent pulmonary artery

A

Chronic bronchitis.

54
Q

You see a CXR with enlarged lung fields, flattened diaphragm, trapped air (dark lung areas), decrease in vascular markings, and bullae.

A

Emphysema.

55
Q

What are bullae and what do they look like?

A

They signify loss of airspaces. Large bubbles of dark air. No gas exchange.

56
Q

Talk me through bronchiectasis.

A

Irreversible bronchial dilation caused by inflammation of the MEDIUM sized bronchi. This then destroys the muscular and elastic tissues of the bronchial walls which then collapse easily. This causes obstruction of airflow and an inability to clear mucous secretions leading to further lung infection and more problems all over again.

57
Q

What infection is the most common cause of bronchiectasis?

A

H. Flu (if not caused by cystic fibrosis)

58
Q

What infection is the most common cause of bronchiectasis in a cystic fibrosis patient?

A

Pseudomonas (M. Cat also very common. If it’s viral…think aspergillus )

59
Q

What does a bronchiectasis patient look like?

A

Daily chronic cough with FOUL SMELLING SPUTUM.

60
Q

What is bronchiectasis responsible for when it comes to blood?

A

It is the most common cause of massive hemoptysis. Hemoptysis is EXTREMELY common with bronchiectasis due to the erosion of the bronchial tree

61
Q

What is the most common cause of hemoptysis in general though?

A

Acute bronchitis and lung cancer.

62
Q

Where will you hear crackles with bronchiectasis?

A

Bases

63
Q

How would you test for bronchiectasis?

A

High resolution CT scan

64
Q

What is the sign you may see?

A

Signet ring sign. Bronchus and pulmonary artery should be the same size. But with this…the bronchus will be much larger.

65
Q

What will PFT’s show?

A

Decrease in FEV1 and FVC

66
Q

What would you do if they had an aspergillus bronchiectasis? What would it look like?

A

Thick brown sputum. Treat with corticosteroids and Itraconazole. Surgery if symptomatic

67
Q

What would you do if they had an Pseudomonas bronchiectasis?

A

Fluoroquinolone, zosyn, aminoglycoside, or cephalosporin

68
Q

What if it’s the mycobacterium avium complex or MAC?

A

Clarithromycin + ethambutol

69
Q

What are the empiric bronchiectasis drugs?

A

Ampicillin, amoxicillin, bactrim

70
Q

What abx has anti-inflammatory properties?

A

Azithromycin.

71
Q

Cystic fibrosis is autosomal ____

A

Recessive

72
Q

What does cystic fibrosis do?

A

Prevents chloride movement out of the cell (meaning water can’t leave) making a TON of mucous get stuck in the lungs, pancreas, liver, intestines.

73
Q

What does a classic CF pt look like?

A

Young with bronchiectasis, pancreatic insufficiency, growth delays, and infertility. Can’t breath, digest, grow, or make love

74
Q

What vitamin deficiencies are common?

A

Ah…Don’t Even Know!!! (ADEK)

75
Q

What are CF poops like?

A

Large, greasy, foul smelling turds.

76
Q

What are the respiratory issues of a CF patient?

A

Um…everything. Lots of infections (pseudomonas, staph, H. flu, etc.), productive cough, SOB, chest pain, and lots of SINUS INFECTIONS

77
Q

A full term infant has meconium ileus.

A

Think CF for shizzle

78
Q

What test for CF?

A

Sweat chloride then CXR.

79
Q

Tell me what causes sarcoidosis

A

Exaggerated T cell response to antigens or self antigens causing inflammation and granulation formation.

80
Q

What systems are most commonly affected by sarcoidosis?

A

Lung, skin, lymph nodes, and eyes in that order

81
Q

What are granulomas and why are they bad?

A

They form from a mass of immune cells. They are bad because they take up space and disrupt the normal function of the tissue in which they form

82
Q

Where are the nodes enlarged? What are the dx findings?

A

Hilar lymph nodes. Pt will have a dry nonproductive cough, dyspnea, and chest pain.

83
Q

What skin findings are associated with sarcoidosis? Are the specific to sarcoidosis? What other things might they be found in if not?

A

Erythema nodosum. Bilateral tender red nodules on anterior legs. They are not specific. May also be seen with coccidiomycosis.

84
Q

What other skin findings are virtually pathognomonic for sarcoid?

A

Lupus pernio (violaceous raised discoloration of noes, ear, cheek, that resembles FROST BITE. Think SARCOID = SO COLD (frost bite face) must be LUPEE to go out in this.

85
