CANDIDA ALBICANS
1. thrush --> friable white plaques ("curd like") that leave erythema/bleeding
when scraped
--> tx = nystatin swish + swallow
2. esophagitis --> odynophagia, GERD, epigastric pain, N/V and endoscopy shows
white linear plaques/erosions
--> tx = fluconazole PO
3. vulvovaginal --> pruritus, burning, white, thick, curd-like vaginal discharge
--> tx = fluconazole, miconazole, clotrimazole PO
4. intertrigo --> beefy red erythematous rash with distinct scalloped borders &
satellite lesions in moist/macerated areas
--> tx = clotrimazole topical
5. fungemia/endocarditis --> seen in immunocompromised
--> tx = amphotericin B IV
budding yeast & pseudohyphae
erythema infectiosum --> 5th disease (parvovirus B19)
- slapped cheeks + "lacy" rash
- can lead to APLASTIC CRISIS --> this is because parvovirus destroy reticulocytes,
leading to no RBC production!
,- associated with fetal loss in pregnancy (hydrops fetalis)
- tx = supportive care

TYPE 2 --> anti-Bodies (B)
- antibody-mediated (cytotoxic)
- ex. Rh and ABO hemolytic disease of newborn, autoimmune diseases
TYPE 3 --> Complex

- ex. vasculitis and serum sickness
