Pulmonology Flashcards
Most common cause of cancer death in the world
Lung carcinoma
90% of lung cancer cases are associated with
Smoking
25% of lung cancer is ___________, and 75% is ___________
Small-cell
Non small-cell
Most common type of non-small cell lung cancer, and second most common
Adenocarcinoma
Squamous cell carcinoma
Screening for lung cancer
- > 55 y/o
- 30 pack year smoker
- Must have smoked in last 15 years
Screen annually w/ low dose chest CT
Stop screening at 80 or if stopped smoking in 15 years
Signs/Symptoms of lung cancer
Persistent cough
Hemoptysis
Weight loss
Diagnosis of lung cancer
- CXR
- Chest CT
- Biopsy
Very aggressive type of lung cancer, where majority will have metastasis at time of diagnosis
Small cell carcinoma
Small cell carcinoma is associated with what diseases?
- SIADH
- Cushing’s syndrome
- Lambert Eaton’s syndrome
Risk factor for sleep apnea
Obesity
Physical airway obstruction (may be due to external airway compression, decreased pharyngeal muscle tone, increased tonsillar size or deviated septum)
Obstructive Sleep Apnea
Snoring, unrestful sleep, nocturnal choking, large neck circumference, crowded oropharynx
Obstructive Sleep Apnea
Diagnosis of sleep apnea
In laboratory polysomnography
Labs: polycythemia
Management of sleep apnea
CPAP is mainstay
Behavioral - weight loss, exercise, abstaining from alcohol
Oral appliances can be tried
Surgical correction
Complications of sleep apnea
Pulmonary hypertension
Arrhythmias
Reverse hyperirritability of the tracheobronchial tree, leading to airway inflammation and bronchoconstriction
Asthma
Most common chronic childhood disease
Asthma
Samter’s Triad
- Asthma
- Nasal polyps
- ASA/NSAID allergy
Classic triad of symptoms of asthma
- Dyspnea
- Wheezing
- Cough (esp at night)
Clues to severity of asthma
Steroid use
Previous intubations
ICU/hospital admissions
Prolonged expiration with wheezing, hyperresonance to percussion, decreased breath sounds, tachycardia
Asthma
Gold standard testing for asthma
Pulmonary Function Test showing reversible obstruction
Diagnosis for asthma
- PFTs
- Bronchoprovocation - bronchodilator challenge test (> 12% increase in FEV1)
- Peak Expiratory Flow Rate
- Pulse Oximetry
- ABG - hypoxia and hypercapnia
- CXR
S/E of short acting beta agonists (SABA)
Tachycardia Arrhythmias Muscle tremors CNS stimulation Hypokalemia
S/E of ipratropium (anticholinergic)
Thirst Blurred vision Dry mouth Urinary retention Dysphagia Acute glaucoma BPH
S/E of inhaled corticosteroids - beclomethasone, flunisolide, triamcinolone
thrush - using spacer and rinsing mouth after inhaler decreases risk
Adjuncts for asthma management
IV Magnesium - bronchodilator
Omalizumab - used in severe, uncontrolled asthma
Inflammation of trachea/bronchi (conducting airways). Often follows URI
Bronchitis
Bronchitis is mostly caused by:
Viruses
Adenovirus
Parainfluenza, influenza, etc.
Cough is hallmark, +/- productive, may last 1-3 weeks, symptoms similar to pneumonia sometimes
Bronchitis
