The Comeback Kid?

Balloon angioplasty revolutionized coronary revascularization; however, elastic recoil and restenosis caused by cellular proliferation are major drawbacks of angioplasty.

Being relatively inert, safe, stable and non-irritating, physical sunscreens are particularly useful for patients with sensitive skin who cannot tolerate chemical sunscreens. However, they form a thick visible pigment layer on the skin. To o...
