This Issue's Rounds Question -
Please tell us: What is Preiser's Disease? (Question submitted by Brad DeWagner)

(responses to be published in next issue)

In the last issue of Body Cast, Rounds asked: The term CREST is an acronym derived from the five most prominent features. What are they?

The following answers were received:

From Cathy Gaudon, Cam Longphee and Bert Sheppard:
This is a dermatological disease. Stick to ortho. C - Calcinosis R - Raynaud's phenomenon E - Esophageal dysfunction S - Sclerodactyly T - Telangiectasia

From Jim Carragher and Lori MacDonald:
As above. CREST is a systemic inflammatory rheumatic disease and usually results in more pathologies than the five symptoms above.

From May Jane Buchner:
As above. You only need two of the five symptoms to be diagnosed with the disease. It is associated with systemic sclerosis.
