candidiasis
fungal infections that are superficial
mycoses or dermatophytes
types of common fungi
yeast = candida albicans
superficial dermatophytes = tineas
-lives on keratinized tissues of skin, hair, nails

treatment:
Po systemic anti-fungals bid for 4-6 weeks
topicals are not effective
tinea versicolor
Ringworm that affects the skin of the upper chest, back, or arms

fungal infection that mostly affects lungs
histoplasma capsulatum - fungus that lives in the soil
occurs around 10 days after exposure
symptoms: usually self-limiting and stays in the lungs
treatment: usually none; systemic antifungals
what is blastomycosis
caused by blastomyces fungus
typically affects lungs
acquired by breathing in the spores - AIRBORNE
symptoms appear 3 weeks to 3 months after exposure
most people do NOT get sick - flu like symptoms
treatment: systemic antifungals for severe cases for 6 months to 1 year
what is pneumocystis
causes a form of pneumonia: pneumocystis pneumonia

Cryptococcus meningitis
fungus found in soil bird droppings
infection in the meninges - rare in healthy people
occurs in a few days to weeks from contact
symptoms: nausea/vomiting, change in mental status, lethargy, sensitivity to light
Treatment IV/PO antifungals
cryptococcus: pulmonary infection
acquired from inhalation of the fungus found in soil
causes a severe pneumonia with respiratory failure
incubation times vary from 2-11 months after exposure
symptoms: SOB, coughing, fever, mental status changes
treatment: PO/IV antifungals

dark macules on the face
more common in women
-mask of pregnancy
