First Aid USMLERx Erorrs

Hi there,
I was shocked to see the lengthy 'errata' for First Aid on their website (long error list for each year's edition!!) don't they check all this before publishing those books?..I am now in doubt about the USMLERx Qbank.
What is your experience guys, does the Qbank also contain so many mistakes?? I really want to avoid memorizing wrong stuff.
Thx..

Actually how I first realized that First Aid (2012!!) has errors was at the renal section, where they show different ion channels etc for different parts of the nephron. Well this stuff is quite confusing anyway and it took me a good bit of time to realize that the figures for the thick ascending limb and the distal tubule are mixed up.
boy!

Checking this ERRATa, i noted this:

p. 212 - Pyrazinamide - Pyrazinamide works by blocking pyrazanamide, not mycobacterial fatty acid synthase I.

From what I know, the mech of Action of Pyrazanamide is unknown.

What means blocking parazanamide? whats that?

Is my impression or they have wrongs on their ERRATA too? lol

A 10-year-old boy is brought to the pediatrician after a school-sponsored hearing test shows he has decreased hearing in both ears. He complains of ringing in both ears. The physician confirms the patient's hearing loss and orders an MRI. Bilateral schwannomas are found.

what else is likely to develop?

meningioma
hypopigmented skin spots
macroorchidism
iris hamartomas
osteosarcoma

this question pissed me off!!! they say the answer is meningioma

Is the answer - Hypopigmented skin spots aka cafe-au-lait spots ?
Coz you can see those in both NF type 1 and NF type 2.
Lisch Nodules are iris hamartomas (seen in NF type 1).

I guess they are right, the patient has NF 2 which presents with schwannoma, meningioma, ependymoma and also juvenile cataracts.

http://en.wikipedia.org/wiki/Neurofibromatosis_type_II
NF 1 on the other hand presents with iris hamartomas, optic gliomas, neural tumors, etc...... FA 2011 pg 86

they say only 4% of students answered the q right...
i can see why.
I never saw anywhere that NF2 can be associated w meningiomas. Thats pretty interesting piece of information.

Just did a mistake in a question about LMN and UMN...
I know this is dumb, but:

Fasciculations = LMN lesion

Spasticity = UMN lesion

is that correct?

and what exactly fasciculations are?

yup, you're correct about the UMN and LMN.

Fasciculations are visible random twitches of the muscle fibers.
