Pulmonology (Current) Flashcards
Risk factors for Sarcoidosis
- African American
- Females
- Northern Europeans
Symptoms of Sarcoidosis
- Dry (nonproductive) cough
- Skin: erythema nodosum, lupus pernio
- Parotid gland enlargement
- Anterior Uveitis
- Restrictive cardiomyopathy
- Diabetes Insipidus
What is Lofgren Syndrome in regards to sarcoidosis?
-Erythema nodosum + bilateral hilar LAD + polyarthralgias with fever
Best initial test and what does it show for sarcoidosis
-Bilateral hilar LAD on CXR
What kind of pattern is on a PFT for Sarcoidosis?
Restrictive pattern: normal or increased FEV1/FVC, normal or decreased FVC
What is the most accurate diagnostic for sarcoidosis?
Tissue Biopsy: noncaseating granulomas
What is one other lab that is significant in sarcoidosis?
Increased ACE levels
If the patient is symptomatic and has sarcoidosis, what is the first line treatment?
Oral corticosteroids
What is a pleural effusion?
Abnormal accumulation of fluid in the pleural space
Physical exam findings of a pleural effusion
- Dullness to percussion
- Decreased fremitus
- Decreased breath sounds
- Dyspnea, pleuritic chest pain, cough
Lateral decubitus chest radiographs are the best type of radiographs to get to evaluate for a pleural effusion. What do you see?
Blunting of the costophrenic angles (meniscus sign)
What is the gold standard diagnostic for pleural effusion?
Thoracocentesis
What are the factors of Light’s Criteria? If any of the three are present, it is an exudate cause?
- Pleural fluid protein: serum protein > 0.5
- Pleural fluid LDH: serum LDH > 0.6
- Pleural fluid LDH: > 2/3 of the upper limit of normal LDH
When do you perform a chest tube for the fluid drainage?
If empyema (pleural fluid pH < 7.2, glucose < 40, or positive gram stain) -May inject with streptokinase to facilitate breakup of loculations
Symptoms of a pneumothorax
- Hyperresonance to percussion
- Decreased fremitus
- Decreased breath sounds over affected area
- Unequal respiratory expansion
Initial test of choice for a pneumothorax
Chest radiograph (expiratory upright view preferred)
- Companion lines
- Decreased peripheral markings
Primary spontaneous pneumothorax:
Secondary spontaneous pneumothorax:
Tension pneumothorax:
Traumatic pneumothorax:
Primary: no underlying lung disease
Secondary: underlying lung disease
Tension: positive air pressure pushes trachea and heart to contralateral side
Traumatic: Car accident, subclavian line placement
Stable secondary spontaneous pneumothorax treatment
Chest tube or catheter thoracotomy + hospitalization
Tension Pneumothorax treatment
-Needle aspiration followed by chest tube thoracostomy
Patient education following a pneumothorax
-Avoid pressure changes for a minimum of 2 weeks (high altitudes, smoking, scuba diving, etc.)
Strongest risk factor for sleep apnea
Obesity
First line diagnostic test for sleep apnea
In-laboratory polysomnography (15 or more events per hour)
Treatment for sleep apnea
- Behavioral changes including weight loss, no alcohol, changes in sleep positioning
- CPAP (mainstay)
- Tracheostomy is definitive treatment
What is the first-line in prevention of meconium aspiration?
Prevention of post-term delivery (> 41 weeks) via labor induction and prevention of fetal hypoxia
