Jitka Petrlova at Lund University, Sweden, together with Peter Bond’s team at the A*STAR Bioinformatics Institute, has discovered a strategy that the body uses to neutralize invading microbes. This finding is a critical development in fighting bacteria in skin wounds. Read more.Read More
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. (more…)Read More
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…)Read More
Antibiotic overuse contributes to the problems of antibiotic resistance and healthcare acquired infections, such as Clostridium difficile. Antibiotic stewardship programs improve patient outcomes, reduce antimicrobial resistance, and save money. These programs are designed to ensure patients receive the right antibiotic, at the right dose, at the right time, and for the right duration. (more…)Read More
Researchers at NYU’s Tandon School of Engineering have teamed up with those from the university’s Rory Meyers College of Nursing to develop a machine-learning algorithm that could help detect a lymphatic system disease before doctors are able to.
There is no cure for lymphedema, only physical exercises that can keep the symptoms in check. (more…)Read More
Research shows that a skin-graft harvesting system aids chronic wound recovery and reduces care costs by accelerating the healing process.
More than six million cases of chronic wounds cost $20 billion each year in the United States. Diabetic ulcers, pressure sores, surgical site wounds, and traumatic injuries to high-risk patients account for most wounds that won’t heal. (more…)Read More
Crawford Healthcare, one of the biggest makers of advanced wound-care products in the UK, has won clearance from US regulators for a medical dressing that it says will “save limbs”.
The product, called KerraCel AG, soaks up fluid and bacteria from nasty, oozing wounds and locks it away as a gel. It is also the only dressing of its kind to contain silver at a special concentration to kill all bacteria – even those resistant to antibiotics – that prevent chronic wounds, such as diabetic ulcers and pressure sores, from healing. (more…)Read More
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…)Read More
A new study has identified a peptide, derived from the Komodo dragon, called VK25, which can be synthesized and used as an antimicrobial peptide to promote wound healing.
The new research has identified (see below) a peptide found from the Komodo dragon (Varanus komodoensis), called VK25, which appears to be useful as a cationic antimicrobial peptide (CAMP). There is currently considerable interest in antimicrobial peptides in a world where antibiotic effectiveness is in decline. These peptides are potent, broad spectrum antibiotics which demonstrate potential as novel therapeutic agents. (more…)Read More
Pennsylvania state trooper Matt Uram was talking with his wife at a July Fourth party in 2009 when a misjudged spray of gasoline burst through a nearby bonfire and set him alight. Flames covered the entire right side of his body, and after he fell to the ground to smother them, his wife beat his head with her bare hands to put out his burning hair. It was only on the way to the ER, as the shock and adrenaline began to wear off, that the pain set in. “It was intense,” he says. “If you can imagine what pins and needles feel like, then replace those needles with matches.” (more…)Read More
Although it is described as “one of society’s greatest achievements,” with the aging population, cancer incidence is expected to accelerate rapidly, as 50% of cancer occurs within this age group.(1)
Nutrition therapy is a crucial component of cancer care. Early and continuous nutrition management is necessary to avoid malnutrition, as this is associated with poor clinical outcomes.(2) Often, the elderly already face chronic comorbid conditions, such as high blood pressure, heart disease, lung disease, diabetes, kidney disease, bone disease and arthritis, further complicating their care.(3) (more…)Read More
Ophthalmology 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…)Read More
