Online tool helps control blood pressure long term

By Genevra Pittman NEW YORK (Reuters Health) – In a new study, people with high blood pressure who could communicate with their pharmacists online had better blood pressure control a year after that service ended. Previously researchers had found that patients randomly assigned to the web-based pharmacy care did better than those who used a patient website but had no extra help or were only trained to monitor their blood pressure at home.

Vitamin C may not treat gout: study

While the recommendation for kidney stone prevention has been to drink a lot of fluids, the study suggests that it’s not just the amount of fluid but the type of drink that also matters. Dr. Gary Curhan, the senior author of the study, said patients often ask for dietary advice to help prevent kidney stones. …

More patients than docs report skin surgery problems

By Genevra Pittman NEW YORK (Reuters Health) – More than one quarter of people being treated for non-melanoma skin cancer in their doctor’s office reported some type of complication after surgery, in a new study. About half of those complications were medical problems related to the cancer-removing procedure, including pain, infections and slow wound healing. But just 3 percent of doctors noted a complication in the same patients’ medical records, researchers reported this week in JAMA Internal Medicine. …
