29
How do we test for ALK rearrangement?
FISH
30
What is the main center for sleep?
VLPO in the hypothalamus. It secretes GABA
31
What med is used for prophylaxis treatment (e.g., for exposed family members)?
isoniazid
32
What's the most common presenting symptom of Squamous cell carcinoma of the larynx?
hoarseness
33
What's the most common benign tumor of the lung?
pulmonary hamartoma
34
What are the most common immunostains used for an adenocarcinoma workup?
CK7, CK20, and TTF1
35
which lung cancer is associated with hypercalcemia?
squamous cell carcinoma; due to tumor production of PTHrP
36
What's the MOA of Pyrazinamide?
blocks bacterial trans-translation [Ubiquitous and essential bacterial process that resolves stalled translational complexes and recycles ribosomal subunits.]
37
What are the most active first line agents for TB?
rifampin and isoniazid
38
How are obstructive sleep apnea and central sleep apnea different (in terms of definition)?
* obstructive sleep apnea: respiratory effort against airway obstruction (throat is collapsed) * central sleep apnea: throat is open but no respiratory effort (due to CNS injury/toxicity)
39
What are the adverse effects of Ethambutol?
optic neuritis (decreases visual acuity and causes red-green color blindness)
40
often presents with a mass with a central cavitation
squamous cell carcinoma of the lung
41
How can you alleviate peripheral neuropathy caused by Isoniazid?
give b6 (pyridoxine)
42
When should you order sputum tests?
1. patients with CAP who are at risk for pseudomanas (COPD patient on prednisone) or unusual bacterial pathogen (like legionella) 2. patients with HAP, HCAP, VAP 1. if you suspect fungus or TB
43
Histologic features that are considered characteristic of squamous cell carcinomas:
1. Evidence of keratinization (production of pink keratin globs) 2. Prominent intercellular bridges (represent desmosomal connections between squamous cells)
44
What are the endothelin receptor antagonists used to treat pulmonary artery hypertension?
Bosentan and Ambrisentan
45
Which neurotransmitters play a vital role in stabilizing the waking/arousal center?
orexin/hypocretin
46
List the first line agents for treating TB
rifampin, isoniazid, pyrazinamide, ethambutol RIPE
47
Which gene mutation is present in Congenital Central Alveolar Hypoventilation Syndrome?
mutation of PHOX2B gene
48
Benzodiazepine receptor agonists are used as sleep meds instead of benzos themselves. Why?
benzo receptor agonists don't have as long of half lives, and they work on specific sites of sleep which minimizes side effects
49
Most common type of lung cancer in never or light smokers
adenocarcinoma
50

PCR

63
Pulmonary hypertension with unclear multifactorial mechanisms
group 5 pulmonary hypertension
64
Primary pulmonary hypertension has familial forms that are related to inactivating mutations of \_\_\_\_\_, leading to \_\_\_\_\_\_,
*BMPR2* leading to proliferation of vascular smooth muscle
65
MOA of rifampin?
inhibits bacterial (but not human) DNA- dependent RNA polymerase --bactericidal
66
What will superior vena cava syndrome cause in a patient?
-facial plethora -jugular venous distention in neck -edema in upper extremities
67
Which Phosphodiesterase-5 inhibitors are approved to treat pulmonary artery hypertension?
sildenafil and tadalafil
68
