Sketchy: Screamatodes Flashcards
What is the tx for Wuchereria bancrofti?
Diethylcarbamazine
Cue:
- WolfMan, sleeping in a chair with bent legs, wearing a sleep mask with a stinky dog poop bag nearby
- Wolf Man = Toxocara canis
- bent legs = albendazole (tx)
- sleep mask = causes blindness
- dog poop = dog feces transmission
Cue:
- Swamp Creature surrounded by flies and covered in spots reading “Diet and Carbs” magazine and sitting in a chair with bent legs
- Swamp Creature = Loa Loa
- flies = deer fly transmission
- spots = subcutaneous angioedema
- Diet and Carbs = Diethylcarbamazine (tx)
- bent legs = Albendazole (tx)
How do you get Dracunculus medinensis?
drinking water contaminated with copepods containing larvae
What organism is also called African Eyeworm?
Loa Loa
Drinking water contaminated with copepods containing larvae will give you _____.
Dracunculus medinensis
What organism can be seen crawling across the pt’s eyeball?
Loa Loa
How is Loa Loa treated?
Diethylcarbamazine and Albendazole
How is Toxocara canis transmitted?
food contaminated with dog or cat feces
How is Loa Loa transmitted?
deer flies
Cue:
- sign that says “No dumping, drains to river”
river = Ivermectin (tx for Onchocerca volvulus)
How is Onchocerca volvulus treated?
Ivermectin (“river mectin”)
How is Wuchereria bancrofti diagnosed?
thick blood smear
What does Loa Loa cause?
transient subcutaneous and conjunctival angioedema
How is Loa Loa diagnosed?
microfilariae present on blood smear
What is unique about Toxocara canis infections?
the larvae never mature within the human- they just circulate for years
Cue:
- coughing Witch lady wearing parachute pants and a shirt with a ruffled collar and sleeves
- coughing = from microfilariae infection in lung
- witch = Wuchereria bancrofti
- parachute pants = elephantiasis
- ruffled collar/sleeves = cervical/axillary lymphadenopathy
In Wuchereria bancrofti, _______ travel to the lungs where they cause a hypersensitivity reaction and therefore a cough.
microfilariae
What are the skin findings for Onchocerca volvulus?
- puritic papules –> hyperpigmented spots
- hypopigmented spots on shins of older pts (onchodermatitis)
What are the 2 most common causes of infectious blindness?
- Chlamydia trichoma
- Onchocerca volvulus
In _______, microfilariae travel to the lungs where they cause a hypersensitivity reaction and therefore a cough.
Wuchereria bancrofti
What causes Visceral/Ocular Larva Migrans?
Toxocara canis
Cue:
- Dracula drinking at a water cooler with paper cups attached, and his untied shoelaces wrapped around the legs of the water cooler
- Dracula = Dracunculus medinensis
- shoes untied = worms crawling out of skin ulcers
- drinking water = transmission
- paper cups = cup-e-pods = copepods
- shoelaces around water cooler = wrap worms around sticks to pull out of pt
How is Dracunculus medinensis treated?
- slowly extract worm out of skin using a stick
- metro
How do you get Wuchereria bancrofti?
mosquito deposit larvae on the skin –> enter skin and lymphatics
Cue:
- kid in pink shooting granules with a slingshot
eosinophils
How is Onchocerca volvulus diagnosed?
presence of microfilariae in skin biopsy under microscope
What organism causes River Blindness?
Onchocerca volvulus
What is the tx for Toxocara canis?
albendazole
How does Onchocerca volvulus cause blindness?
microfilariae in the eyeball
Cue:
- black fly man with stains on his lab coat and pants
- Onchocerca volvulus
- black fly = transmission
- stains = onchodermatitis (hyper and hypo-pigmented spots)
In Wuchereria bancrofti, microfilariae travel to the lungs where they cause a _______ and therefore a _____.
hypersensitivity reaction, cough
What does Wuchereria bancrofti cause?
elephantiasis
How is Dracunculus medinensis diagnosed?
worms come out of ulcers on the pt’s skin (usu lower extremities)
Cue:
- witch reading “Diet and Carb Magazine”
tx for Wuchereria bancrofti = Diethylcarbamazine
