* Disease Profiles : Certain diseases or syndromes may be a sign of another underlying disease. For example, osteoporosis may have several causes one of which is Cushings Syndrome ( excess coriticosteroid production by the adrenal gland).
Therefore a search on "Osteoporosis" will bring up Cushing's Syndrome, among others.
