Pneumonia Flashcards
Name the Typical Pneumonias
Strep Pneumoniae, Hemophilus Influenza, Moraxella Catarrhalis, Viral, Stephylococcus
Name the Atypical Pneumonias
Legionnaire’s disease, Mycoplasma, Chlamydia (TWAR)
Most common pathogen for pneumoniae?
Streptococcus Pneumoniae
Major difficulty in Treating Strep Pneumo?
Penecillin resistence
Clincal Manifestation of strep pneumo
Fever, chills, rigor, red-rust sputum, mental confusion in elderly
Pneumo seen especially in smokers
Heamophilus influenza
Heamophilus resistant to?
Ampicilin and erythromycin
Beta-lactamase producing pneumonia?
Heamophilus
Gram negative diplo, seen in coexistant lung disease such as COPD, associated with bronchitis, beta-lactamase producer?
Moraxella
Moraxella resistant to?
Penicillin, amoxicillin, ampicillin
Symptoms: mental confusion, diarrhea, no headache, no ear pain, no rash, no pharyngitis, no cardiac involvement, +relative bradycardia, patchy/consolidated CXR, increased liver transaminases, microscopic hematuria
Legionnaires
Symptmos: +/- mental confusion, headache, +/- ear pain, diarrhea, +/- rash, +pharyngitis, rare cardiac involvmeent, no relative bradycardia, pathy CXR, cold agglutinins
Mycoplasma
Symptoms: no mental confusion, no headache, +/- ear pain, no diarrhea, no rash, yes pharyngitis, no cardiac involvement, no relative bradycharida, single circumscribed infiltrate on CXR
Chlamydia
Risk factors for enteric gram - organisms
residence in nursing home, underlying cardiopulmonary disease, multiple medical comorbitities, recent antibiotic therapy
Risk factors for pseudomonas aeruginosa?
underlying structueral luing disease (bronchiectasis), daily corticosteroid therapy, broad spectrum antibiotic therapy for over seven days in th previous month, sever malnourishment
Risk factors for penicillin resistent and drug resisten pneumococci?
Age over 65, beta lactam therapy within the last 3 months, alcoholism, immunosupressive condition, multiple comorbities, exposure to a child in a day-care center
What is strep pneumo resistant to and how?
resistant to B-lactam antibiotics due to alteration in penicillin binding proteins.
What is Haemophilus resistant to and how?
Resistant to ampicillin and amoxicillin due to B-lactamase produciton
What is moraxella resistent to and how?
Resistant to ampicillin and amoxicillin due to B-lactamase production
