Pruritic--itchy as heck
Urticarial--rash-like
Papules--small, circumscribed elevations of the skin, varying in size from pinpoints to small peas...
Plaques--scales, flakes

I presume the "S" stands for syndrome?

I could see how something like this would be brought on by liver toxicity--particularly since this is the time when all kinds of mothers a put on supplement regimes which may be a little overwhelming on the liver...

I'm still searching too...
