Pulmonology Flashcards
Bronchitis-common organisms
90% rhinovirus, Coronavirus, and RSV
Bronchitis-Tx
Supportive, B2 agonist, COPD: exacerbations-First line: 2nd gen cephalosporin, 2nd line: 2nd generation macrolide or bactrim;
Abx indicated: Elderly with cardiopulmonary dz and cough >7-10 days or immunocompromised
Epiglottitis: Most common organism & symptoms
Haemophilus Influenzae Tybe B–most common
S/S: Drooling (80%), Muffled voice, severe dysphagia, Tripod position
Epiglottitis Treatment
Secure Airway, Broad-spectrum 2nd or 3rd gen cephalosporin (Cefoaxime or ceftriaxone x 7-10 days)
Croup–AKA and Most common cause
AKA: viral laryngotracheobronchitis
Parainfluenza Virus 1 & 2
Croup Signs/Symptoms
Barking seal-like cough, Inspiratory stridor, “sounds worse than they look” opposite of Epiglottitis
Croup-Diagnostics
PA neck x ray: Steeple sign
lateral X ray: normal (diff Croup from epiglottitis)
Croup-Treatment and vaccination
Mild: supportive care
+ stridor (AT REST): active intervention, Steroids (dexamethasone), Nebulized epi, Humidified O2
Vaccination: kids-DTaP if incompletely immunized; Adults: booster Tdap
what is Reye’s syndrome?
Fatty liver with encephalopathy, May develop 2-3 weeks after onset of influenzae–esp. if ASA ingested
Influenzae-what treatment? And when is it C/I?
Neuraminidase Inhibitors: Zanamivir inhalation (relenza) and Oral oseltamivir (tamiflu)–will decrease severity if given within 48 hours of onset of symptoms (C/I in children <12 years)
C/I of the Influenza vaccination
Hypersensitivity to eggs, during febrile illness, thrombocytopenia
Pertussis: Cause?
Bordetella pertussis (gram negative bacteria)
Describe the 3 stages of Pertussis
Catarrhal Stage (1-2 weeks): Most infectious stage, URI symptoms
Paroxysmal stage (2-4 weeks): Spasms of rapid coughing; Deep, high pitched inspiration (the whoop)
Convalescent stage: (4 weeks after onset)
cough disappears, Decreased symptoms
Pertussis: Treatment of choice
Erythromycin (avoid in infants <1 y/o)
Most common Pneumonia Etiology of alcoholics and sputum
Klebsiella Pneumoniae; Sputum: Currant jelly
Most common Pneumonia etiology in cystic fibrosis patient:
Pseudomonas
Most common Pneumonia etiology in HIV/AIDs
Pneumocystic Jirovecii
Most common Pneumonia etiology in IV drug users
S. Aureus and Tuberculosis
Most common Nosocomial Pneumonia
Staph Aureus; Pseudomonas Aeruginosa (ICU)
Most common Cause of PNeumonia. (CAP); Gram stain?
Streptococcus Pneumoniae: Gram stain-Gram Positive Diplococci
CXR mycoplasma Pneumonia vs. Typical
Mycoplasma: Patchy Interstitial Infiltrates; Typical: Lobar infiltrates
Risk factors for the fungal Pneumonia Histoplasma Capsulatum
Ohio and Missippi river valleys, found in soil, Bat exposure, Cave explorers
Risk Factors for the Fungal Pneumonia: Coccidioides Immitis
Dimorphic fungus, Construction workers
Most common Oppurtunistic infection in HIV patients–Characteristics, CD4 counts, diagnostics, and TX
Pneumocystis Jiroveci
CXR: Butterfly pattern
CD4 count: 90% of patietns
Tx/Prophlyaxis: Bactrim
Symptoms of Carcinoid syndrome
Flushing, diarrhea, wheezing, hypotension
If given in a test scenario—Think carcinoid tumor
Type of lung cancer most likely to metastasize early and rarely amenable to surgery?
Small cell lung cancer (oat cell)
Where does Small cell lung cancer originate?
Central bronchi
