Every year thousands of people have cardiac catheterizations, or angioplasties. That's when a doctor threads a catheter to your heart arteries to look for blockages and other issues. If they do see a blockage, they can decide if placing a stent to open it would be beneficial. For years, doctors have used the artery near your groin as an access point for this procedure. But now, some are using the artery in your wrist. Why? Because it may be safer and easier on patients.
Nine million. That's how many people go to the doctor every year because of dermatitis. It's an itchy, ugly rash you get when you're allergic to things such as additives in skin lotions or detergents. And for many, trying to figure out what products are safe can be daunting — labels can be confusing. A doctor at Mayo Clinic wants to change that. He's developed a smartphone app to make life a lot easier for people with dermatitis. It tells you what products are safe for you and which ones could cause problems.
