Guess that germ
This is the most common cause of community-acquired bacterial pneumonia.
What is Streptococcus pneumoniae?
Rust-colored sputum is classically associated with this organism.
What is Streptococcus pneumoniae?
This imaging study is commonly used to confirm pneumonia.
What is a chest X-ray?
In severe hypoxemia refractory to supplemental oxygen, patients may require this invasive respiratory intervention.
What is mechanical ventilation
Infection spreading into the pleural space causing pus accumulation is known as this.
What is empyema?
This bacterium is commonly associated with pneumonia following influenza infection.
What is Staphylococcus aureus?
This type of sputum is classically associated with Klebsiella pneumoniae infection.
What is currant jelly sputum?
In lobar pneumonia, the alveoli fill with this inflammatory material.
What is exudate (fluid, neutrophils, and debris)?
This class of antibiotics is commonly used for atypical pneumonia organisms like Mycoplasma.
What are macrolides?
Necrotizing pneumonia can lead to cavitary destruction of lung tissue forming this complication.
What is a lung abscess?
Aspiration pneumonia is most commonly caused by these types of bacteria. (Name at least 1)
What are anaerobic bacteria? Prevotella, Porphyromonas, Fusobacterium nucleatum Peptostreptococcus species
A respiratory rate greater than this threshold is one of the CURB-65 severity criteria.
What is 30 breaths per minute?
This virulence factor of Streptococcus pneumoniae inhibits phagocytosis.
What is the polysaccharide capsule?
Patients with MRSA pneumonia are commonly treated with these two antibiotics.
What are vancomycin or linezolid?
Diffuse alveolar damage leading to refractory hypoxemia is characteristic of this syndrome.
What is acute respiratory distress syndrome (ARDS)?
This atypical organism lacks a cell wall, making beta-lactam antibiotics ineffective against it.
What is Mycoplasma pneumoniae?
"This physical exam finding refers to the ability to hear whispered words clearly through the stethoscope over an area of consolidation."
Yes! First team to spell it out on the board gets +200
This inflammatory biomarker is typically elevated in bacterial CAP but low in viral CAP, and its synthesis is triggered by bacterial cytokine responses
What is procalcitonin?
Name all five components of the CURB-65 pneumonia severity score (must include the reference numbers)
Name all four major SIRS criteria used to identify systemic inflammation.
This intracellular pathogen associated with contaminated water sources can cause hyponatremia and diarrhea along with pneumonia.
What is Legionella pneumophila?
A procalcitonin level at or above this threshold (in μg/L) has been used as an indication of bacterial pneumonia.
What is 0.25 μg/L?
What are the four classic stages of lobar pneumonia? :)
What congestion, red hepatization, gray hepatization, and resolution?
A 45-year-old man with HIV presents with fever, weight loss, hepatosplenomegaly, diffuse lymphadenopathy, and pancytopenia. Chest imaging shows diffuse reticulonodular infiltrates. Urine antigen is positive for a dimorphic fungus endemic to the Ohio and Mississippi River valleys. What is the treatment of this disseminated condition?
What is amphotericin B for severe/disseminated disease, followed by oral itraconazole for step-down and maintenance therapy?
First-line therapy for BOOP typically involves this class of medication, which leads to rapid clinical and radiographic improvement in most patients.
What are systemic corticosteroids?
