FDA approves first shock wave device made to heal wounds

person in a costume © Provided by Engadget Using "acoustic shock waves" to promote healing isn't just for Overwatch, as Sanuwave has obtained FDA approval for its Dermapace System (Pulsed Acoustic Cellular Expression = PACE). Its approval is specifically to help heal foot ulcers in diabetic patients, where damage to blood vessels and nerves can lead to reduced circulation, infection and sometimes amputation. The Dermapace mechanically stimulates the wound, which Sanuwave says promotes healing. Like several other "first" FDA approvals we've seen recently, this device went through the de novo review process designed specifically to get new technology on the market.

After two double-blind studies, the results showed an increase in wound healing at 24 weeks with a 44 percent wound closure rate with the real Dermapace device, vs. a 30 percent closure rate for patients treated with a fake system. Now that this device has been approved, it also opens the door for similar technology, if it can show that it's "substantially equivalent."

R. Tiglao Exposed LTO Records Showing Aquino Never Bought or Sold a Porsche

Veteran columnist Rigoberto Tiglao exposed the Land Transportation Office (LTO) records of former President Benigno Aquino III showing that he never bought or sold an expensive Porsche car. The LTO records proved that the former President did not sold his Porsche 911 Carrera car which he claimed he bought for P5 million. The controversial Porsche car of the former President made headlines just months into his presidency but he explained that he bought the luxury car with the proceeds he got when he sold his BMW. Because of the furor from such display of opulence, Pres. Aquino claimed to have sold it six months later for exactly the same price. According to Tiglao during that time he asked through his column the LTO to release the car's deed of sale and registration to prove that it was not a gift from a Chinese-Filipino tycoon as rumored by some individuals critical to the President.
