Circumcised North Americans were described by Columbus upon arrival to the continent; circumcision was practiced by Australian aboriginals, native South Americans, and Pacific Islanders.

Does Heyde Syndrome (The Association Between Aortic Stenosis And Intestinal Angiodysplasia) Exist?

By Laura Dunn, MD

The Heart in Acromegaly

By Ari Pollack, MD

Faculty Peer Reviewed

 The onset of acromegaly is subtle, and its progression is usually very slow. In fact, the usual interval from the onset of symptoms until diagnosis is about twelve years. The manifestations of acromegaly result from excessive secretion of growth hormone (GH), which targets the liver, resulting in stimulation of hepatic secretion of insulin-like growth factor-1 (IGF-1), which causes many of the clinical manifestations of acromegaly.  The most common cause of acromegaly is…
