Diabetic foot ulcers heal faster with probiotic supplementation

Findings from a randomized controlled trial revealed that patients with a diabetic foot ulcer, who received probiotic supplementation for 12 weeks, experienced faster wound healing coupled with an improved glycemic and lipid profile compared with patients assigned a placebo. Read more.

Bacterial biofilms, begone

bacterial biofilm

By some estimates, bacterial strains resistant to antibiotics — so-called superbugs — will cause more deaths than cancer by 2050.

Colorado State University biomedical and chemistry researchers are using creative tactics to subvert these superbugs and their mechanisms of invasion. In particular, they’re devising new ways to keep harmful bacteria from forming sticky matrices called biofilms — and to do it without antibiotic drugs. (more…)

Salivary peptide promotes wound healing, research reveals

salivary peptide wound healing wca

A study published online in The FASEB Journal delves into the mystifying fact that wounds in your mouth heal faster and more efficiently than wounds elsewhere. Until now, it was understood that saliva played a part in the wound healing process, though the extent of its role was unknown. The study examined the effects of salivary peptide histatin-1 on angiogenesis (blood vessel formation), which is critical to the efficiency of wound healing. Researchers found that histatin-1 promotes angiogenesis, as well as cell adhesion and migration. (more…)

Cervical Biopsy more efficient, less painful via new method

Can new tool make cervical biopsy more efficient, less painful

Physicians evaluate new device to test for cervical cancer. Comparison of Tissue Yield Using Frictional Fabric Brush Versus Sharp Curettage For Endocervical Curettage.

Women undergoing cervical biopsies might have lower odds of repeat tests with a rotating fabric brush than a sharp instrument because the soft device may capture more cells for analysis, a recent study suggests. Furthermore, biopsies with the softer tool may be less painful, researchers say. Cervical biopsies sometimes fail to collect enough cells from the cervix to accurately test for cancer, in which case another biopsy is needed.

A new way of healing wounds in the future discovered by scientists

Scientists at Ohio State University have developed a new method that has the capability of changing the body’s existing cells into new cells to promote healing. The method, called Tissue Nanotransfection (TNT), reprograms cells through a device that uses nanotechnology. The way it would work: First, doctors would apply a light electrical stimulation to the surface of the skin. They would then place a small chip about the size of a cuff link onto the site of the wound. In less than a second, this chip would deliver reprogramming factors (pre-programmed DNA or RNA) non-invasively into living skin cells via a high-intensity, focused electric field, converting them into whatever type of cells a scientist or doctor may choose.

Wounds that won’t heal can be devastating

diabetic foot ulcer

Carol Emanuele beat cancer. But for the last two years, the Philadelphia woman has been fighting her toughest battle yet. She has an open wound on the bottom of her foot that leaves her unable to walk and prone to deadly infection.

In an effort to treat her diabetic wound, doctors at a clinic in Northeast Philadelphia have prescribed a dizzying array of treatments. Freeze-dried placenta. Penis foreskin cells. High doses of pressurized oxygen. And those are just a few of the treatment options patients face.

“I do everything, but nothing seems to work,” said Emanuele, 59, who survived stage 4 melanoma in her 30s. “I beat cancer, but this is worse.” (more…)

New Approach to Wound Healing Easy on Skin, Tough on Bacteria

wound healing

Washington, D.C. — In a presentation  to the American Chemical Society meeting, Ankit Agarwal, a postdoctoral researcher at the University of Wisconsin-Madison, described an experimental approach to wound healing that could take advantage of silver’s anti-bacterial properties, while sidestepping the damage silver can cause to cells needed for healing.

Silver is widely used to prevent bacterial contamination in wound dressings, says Agarwal, “but these dressings deliver a very large load of silver, and that can kill a lot of cells in the wound.” (more…)

3 reasons why cornea is the new Glaucoma

Glaucoma

development of glaucomaOphthalmology is a great specialty partly because procedures, devices and drugs constantly evolve, keeping us learning and giving our patients better care. Ask your colleagues in other specialties, and you’ll find that the pace of change in most other medical fields is not nearly as rapid as in ours.

Over the past few years, this pace of change has been very evident in glaucoma, where minimally invasive procedures have greatly diminished the frequency of trabeculectomy and tube shunt procedures. In this issue of OSN, our cover story focuses on a specialty that’s now moving as quickly as glaucoma. And here are three reasons I believe cornea will continue to be the “next big thing” in eye care: (more…)

Fish Skin for Human Wounds: Iceland’s Pioneering Treatment

Fish Skin for Human Wounds

The FDA-approved skin substitute reduces inflammation and transforms chronic wounds into acute injuries.

Six hours north of Reykjavik, along a narrow road tracing windswept fjords, is the Icelandic town of Isafjordur, home of 3,000 people and the midnight sun. On a blustery May afternoon, snow still fills the couloirs that loom over the docks, where the Pall Palsson, a 583-ton trawler, has just returned from a three-day trip. Below the rust-spotted deck, neat boxes are packed with freshly caught fish and ice. “If you take all the skins from that trawler,” says Fertram Sigurjonsson, the chairman and chief executive officer of Kerecis Ltd., gesturing over the catch, “we would be able to treat one in five wounds in the world.” (more…)
