SSTI
The causative organism for a wound with "fruity" odor, often seen in burn patients or puncture wounds through a sneaker
What is Pseudomonas aeruginosa?
The most likely diagnosis for a patient with "rice water stools" and severe dehydration.
What is cholera (vibrio cholerae)?
A gray pseudomembrane on the posterior pharynx that bleeds if scraped is pathognomonic for this infection.
What is diphtheria?
What is syphilis?
A target or "bullseye" rash (erythema migrans) is the pathognomonic early sign of this tick-borne disease.
What is lyme disease?
A patient with a history of a cat scratch presenting with regional lymphadenopathy has an infection caused by this organism.
What is Bartonella henselae?
This parasite causes foul-smelling, greasy stools and is often associated with drinking from mountain streams (camping).
What is Giardia lamblia?
The Centor Criteria (fever, exudates, tender anterior adenopathy, no cough) are used to estimate the probability of this infection.
What is Group A strep pharyngitis?
The physical exam finding of a "strawberry cervix" (punctate hemorrhage) is associated with this flagellated protozan.
What is trichomonas vaginalis?
What is Rocky Mountain Spotted Fever?
What is Candidiasis (candida)?
A patient with "pea soup" diarrhea and rose spots on the trunk likely has this specific infection.
What is Typhoid Fever (salmonella typhi)?
An HIV patient with a CD4 count <200 presenting with hypoxia and diffuse infiltrates likely has this fungal pneumonia.
What is pneuocystis jirovecii (PCP)?
This is the preferred diagnostic test (Gold Standard) for both gonorrhea and chlamydia.
What is NAAT (nucleic acid amplification test)?
Prophylaxis with TMP-SMX (Bactrim) is initiated in an HIV patient when the CD4 count drops below this number.
What is 200 (cells/mm3)?
This gram-positive group A cocci is the most common cause of erysipelas and can progress to necrotizing fasciitis.
What is streptococcus pyogenes (GABHS)?
This bacterial cause of bloody diarrhea is a known precipitant of Guillain-Barre Syndrome.
What is campylobacter jejuni?
Exposure to bat or bird droppings in the Ohio/Mississippi River Valleys suggests this fungal cause of pneumonia.
What is histoplasmosis?
Painful, fluid-filled vesicles on an erythematous base are classic for this viral infection.
What is herpes simplex virus (HSV)?
Diagnosis of this mosquito-borne disease is confirmed by visualizing parasites on a Giemsa-stained blood smear (thick and thin).
What is malaria?
The classic "honey-colored crust" seen in impetigo is most commonly caused by this bacteria.
What is staphyloccus aureus?
Diagnosis of this antibiotic-associated diarrhea requires a stool test for Toxin A and B.
What is Clostridioides difficile (C. diff)?
Acid-fast bacilli (AFB) smear and culture is the gold standard diagnosis for this cavitary lung disease.
What is tuberculosis (TB)?
These two HPV types are responsible for 90% of genital warts (condyloma acuminata).
What are HPV type 6 and 11?
If the HIV screening ELISA is positive, this specific test is performed next to confirm the diagnosis and differentiate HIV-1 from HIV-2.
What is the HIV-1/2 differential assay?
