Lyme disease

For transmission of Borrelia burgdorferi, the tick needs to be firmly attached to the skin and have an engorged appearance (generally 36 hrs!). 

Just remember the tick is brown and ixy. One of the UWorld questions I did wanted to mention the tick was brown as compared to RMSF tick (Dermacentor carrying R. rickettsii) which is allegedly black; after brief googling I felt like Dermacentor still looked brown though...so idk.

Cryptococcus

The systemic spread of infection can involve any organ, though skin is the most common extraneural site of infection.

If cutaneous crypto is suspected, BIOPSY + histopath! Grossly, it resembles Molluscum contagiosum. Once cutaneous crypto is dx, look for systemic involvement: CXR, blood and CSF cx, India ink stain for CSF, cryptococcal antigen in serum & CSF.

Terbinafine

The superficial lady in a turban has fine pointed nails.

Terbinafine - treat onchomycosis, taken orally, but not for systemic fungal infections.

Violence is never an answer...but just a visual to match what a question “might” describe.

I tried to convince myself that color-coding the antibiotics with the bacteria would help me remember. 

Also, I can’t stand writing in red, so this was an exercise of multiple things.

Anyone else suddenly want to do arts&crafts when it is study time?

Three thyroid-related “syndromes” associated w use of amiodarone:

Decreased peripheral T4 conversion to T3. More prominent during first 1-3 months, though pts clinically euthyroid. (No tx needed)

Hypothyroidism - Wolff-Chaikoff effect: autoregulatory inhibition of organification/thyroid hormone synthesis because of high iodine content (Tx: levothyroxine)

Amiodarone-induced thyrotoxicosis

Type I: due to increase synthesis of thyroid hormones (Tx: antithyroid drugs)

Type II: due to destructive thyroiditis (Tx: glucocorticoids)

Ascites: Budd-Chiari syndrome

Ascites on ultrasound (>90% cases)

Abdominal pain

In diabetes mellitus, oculomotor nerve (CNIII) neuropathy is ischemic.

CNIII has separate blood supplies for:

Somatic (affected) --> ptosis and down & out gaze

Parasympathetic (intact) - accomodation & pupil light reflex intact

So just imagine the diabetic trying to look forward, but that down-and out eye is gazing at that sweet treat they're trying to avoid :x.  (Pardon my poorly drawn pic!)

Shigella

sHIga toxin is the same toxin in EHEC and EIEC

A: action - inactivate 60S ribosome --> inhibit protein synth --> kill epithelial cell :(

B: binding - bind to microvilli membrane in colon
