Scars are a particularly sore subject for most people. Not only are they aesthetically unpleasing, but some of them can prove painful. That’s why research into minimizing the appearance of scars continues to be a central priority of wound care-related research. In the last several months alone, there have been quite a few exciting such breakthroughs. (more…)

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.

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…)

What exactly is wound exudate? Also known as drainage, exudate is a liquid produced by the body in response to tissue damage. We want our patients’ wounds to be moist, but not overly moist. The type of drainage can tell us what’s going on in a wound.
Let’s look at the types of exudates commonly seen with wounds. (more…)

MUNICH — Local injection of mesenchymal stem cells derived from autologous bone marrow shows promise in healing recalcitrant neuropathic diabetic foot ulcers, a novel study from Egypt shows.
Presenting the results at the European Association for the Study of Diabetes (EASD) 2016 Annual Meeting, Ahmed Albehairy, MD, from Mansoura University, Egypt, said: “In patients who received the mesenchymal stem cells, ulcer reduction was found to be significantly higher compared with patients on conventional treatment after both 6 weeks and 12 weeks of follow-up. This is despite the fact that initial ulcer size was larger in the stem-cell–treated group.” (more…)

Philadelphia – Doctors have found a way to manipulate wounds to heal as regenerated skin rather than scar tissue. The method involves transforming the most common type of cells found in wounds into fat cells – something that was previously thought to be impossible in humans. Researchers began this work at the Perelman School of Medicine at the University of Pennsylvania, which led to a large-scale, multi-year study in connection with the Plikus Laboratory for Developmental and Regenerative Biology at the University of California, Irvine. They published their findings online in the journal Science on Thursday, January 5th, 2017.Fat cells called adipocytes are normally found in the skin, but they’re lost when wounds heal as scars. The most common cells found in healing wounds are myofibroblasts, which were thought to only form a scar. Scar tissue also does not have any hair follicles associated with it, which is another factor that gives it an abnormal appearance from the rest of the skin. Researchers used these characteristics as the basis for their work – changing the already present myofibroblasts into fat cells that do not cause scarring. (more…)

Skin substitutes (also called tissuebased products and dermal replacements) are a boon to chronic wound management when traditional therapies have failed. When selecting skin substitutes for their formularies, wound care professionals have many product options—and many decisions to make.
Repair of skin defects has been a pressing concern for centuries. As early as the 15th century BC, Egyptian physicians chronicled procedures and herbal treatments to heal wounds, including xenografts (skin from another species). The practice of applying allografts (human cadaver skin) to wounds was first documented in 1503. In 1871, autologous skin grafting (skin harvested from the the person with the wound) was tried. Next came epithelial- cell seeding, which involves scraping off the superficial epithelium of healthy skin and transplanting the cells onto the wound. (more…)

Inappropriate footwear is the most common source of trauma in patients with diabetes. Frequent and proper assessment of appropriate footwear is essential for protecting the diabetic foot from ulceration. Here is a step-by-step process for evaluating footwear. Be sure to evaluate footwear with the patient walking, standing, and sitting.
Have you ever ridden a bicycle with a wobbly wheel? The ride isn’t smooth, and you notice every bump in the road. As you focus on your discomfort, you may be distracted from the beautiful vistas you’re riding past. Think of the bicycle as your overall health, which carries you through life. For most of us, learning how to ride a bike begins in childhood as we learn…
Management of biofilm recommendations The Journal of Wound Care has published “Recommendations for the management of biofilm: a consensus document,” developed through the Italian Nursing Wound Healing Society. The panel that created the document identified 10 interventions strongly recommended for clinical practice; however, panel members noted that, “there is a paucity of reliable, well-conducted clinical trials which have produced clear evidence related to the effects of biofilm presence.”
Wound patient’s bill of rights The Association for Advancement of Wound Care has developed the “Wound Care Patient’s Bill of Rights.” The 10 points include the right to: • know what wound treatment options are available to you • know the benefits, risks, and side effects of your wound care treatments • participate in the development of your treatment plan with your wound care team • have…
Sad but true: Much of what we do as healthcare professionals is based on reimbursement. For nearly all the services and products we use in wound care and ostomy management, Medicare, Medicaid, and insurance companies control reimbursement. For many years, these payers have been deciding which interventions, medications, products, and equipment are the best, and then reimbursing only for those items. If we want to use something not on the list,…
Negative pressure wound therapy (NPWT) uses negative pressure to draw wound edges together, remove edema and infectious material, and promote perfusion and granulation tissue development. The tissue stretch and compression created by negative pressure during NPWT promotes tissue perfusion and granulation tissue development through angiogenesis, cellular proliferation, fibroblast migration, increased production of wound healing proteins, and reduction of wound area. NPWT has been used to improve healing in a variety of wounds, including traumatic…
It’s been a stressful day at work—nothing new. One confused patient pulled off her ostomy bag, you’re having difficulties applying negative-pressure wound therapy on another, and a third patient’s family is angry with you. We all experience stressful days, but unfortunately, sometimes we take our stress out on each other. Too often, this ineffective way of identifying and managing stress leads nurses to engage in lateral violence.
The goal of wound-bed preparation is to create a stable, well-vascularized environment that aids healing of chronic wounds. Without proper preparation, even the most expensive wound-care products and devices are unlikely to produce positive outcomes. To best prepare the wound bed, you need to understand wound healing physiology and wound care basics, as well as how to evaluate the patient’s overall health and manage wounds that don’t respond to treatment. (See…
On April 13, 2016, the National Pressure Ulcer Advisory Panel (NPUAP) announced changes in pressure ulcer terminology and staging definitions. Providers can adapt NPUAP’s changes for their clinical practice and documentation, but it’s important to note that, as of press time, the Centers for Medicare & Medicaid Services (CMS) has not adopted the changes. This means that providers can’t use NPUAP’s updates when completing CMS assessment forms, such as the Minimum…
Nurses and therapists often wonder if their license permits them to perform sharp wound debridement. Scope of practice varies significantly from state to state, so it’s imperative to check your state for specific guidance, but we can address some of the challenges clinicians face in deciding whether they can perform this valuable service for patients. Sharp debridement vs. other forms
Imagine you have a health condition that affects your life every day. Then imagine being told nothing can be done about it; you’ll just have to live with it. Or worse yet, your physician tells you the problem is “you’re just fat.”
Many people with lymphedema or lipedema have no idea their condition has a name or that many other people suffer from the same thing. Although lymphedema and lipedema can’t be cured, proper management and resources can help patients cope. This article improves your grasp of these conditions, describes how to recognize and manage them, and explains how to support your patients.
To understand lymphedema and lipedema, first you need to understand how the lymphatic system functions. It makes lymph, then moves it from tissues to the bloodstream. It also plays a major role in the immune system, aiding immune defense. In addition, it helps maintain normal fluid balance by promoting fluid movement from the interstitial tissues back to the venous circulation. (See Lymphatic system: Four major functions.)
If the lymphatic system is impaired from a primary (hereditary or congenital) condition or a secondary problem, lymphedema can result. In this chronic, potentially progressive, and incurable condition, protein-rich fluid accumulates in the interstitial tissues.
Lymphedema occurs in four stages.
Stage 0. During this stage (also called the subclinical or latency stage), transport capacity of the lymphatic system decreases but remains sufficient to manage normal lymphatic loads. Signs and symptomsaren’t evident and can be measured only by sensitive instruments, such as bioimpedance spectroscopy and optoelectronic volumetry. Without such instruments to quantify volume changes, diagnosis may rest on subjective complaints.
In this stage, limited functional reserve of the lymphatic system leads to a fragile balance between subnormal transport capacity and lymphatic loads. Added stress on the lymphatic system (as from extended heat or cold exposure, injury, or infection) may cause progression to stage 1.
Providing appropriate patient information and education, especially after surgery, can dramatically reduce the risk that lymphedema will progress to a more serious stage.
Stage 1. Considered the spontaneously reversible stage, stage 1 is marked by softtissue pliability without fibrotic changes. Pitting can be induced easily. In early stage 1, limb swelling may recede over – night. With proper management, the patient can expect the extremity to decrease to a normal size compared to that of the uninvolved limb. Otherwise, lymphedema is likely to progress to stage 2.
Stage 1 lymphedema may be hard to distinguish from edemas from other causes. Clinicians must rely on the patient history and monitor for swelling resolution with conventional management, such as compression and elevation, or note if swelling persists despite these standard interventions.
Stage 2. Sometimes called the spontaneously irreversible stage, stage 2 is identified mainly from tissue proliferation and subsequent fibrosis (called lymphostatic fibrosis). The fluid component can be removed spontaneously, but removal of the increased tissue proliferation (initially irreversible) takes more time. Tissue proliferation stems from long-standing accumulation of protein-rich fluid; over time, the tissue hardens and pitting is hard to induce. In many cases, swelling volume increases, exacerbating the already compromised local immune defense.
Consequently, infections (particularly cellulitis) are common; these, in turn, increase the volume of the affected area. Proper treatment can reduce volume.
With proper care (complete decongestive therapy [CDT]), lymphedema can stabilize during stage 2. But patients with chronic or recurrent infections are likely to progress to stage 3.
Stage 3. Also called lymphostatic elephantiasis, this stage is marked by further fluid volume increases and progression of tissue changes. Lymphostatic fibrosis becomes firmer and other skin alterations may occur, including papillomas, cysts, fistulas, hyperkeratosis, fungal infections, and ulcers. Pitting may be present. Natural skinfolds deepen (especially those of the dorsum of the wrist or ankle) and, in many cases, cellulitis recurs.
If lymphedema management starts during this stage, reduction can still occur. Even in extreme cases, with proper care and patient adherence to treatment, lymphostatic elephantiasis can be reduced so the leg is a normal or near-normal size.
A thorough physical examination is the gold standard for diagnosing lymphedema. A complete patient history, body-systems review, inspection, and palpation can help determine if edema is lymphedema.
Clinically, the only test with proven reliability and validity in diagnosing lymphedema is the Stemmer sign. Fibrotic changes associated with lymphedema can lead to thickened skin over the proximal phalanges of the toes or fingers. If you can’t tent or pinch the skin on the involved extremity, lymphedema is present (a positive Stemmer sign). However, a negative finding (soft, pliable tissue) doesn’t rule out lymphedema because the condition may be in an early stage, before tissue proliferation and fibrosis have set in.
Although incurable, lymphedema can be managed successfully through CDT. This approach involves proper identification of lymphedema, manual lymph drainage, skin and nail care, patient education, compression, and exercise.
CDT has two phases:
• Phase I, the intensive phase, continues until the extremity has decongested or reached a plateau. The clinician provides treatments and educates the patient about all aspects of CDT to prepare him or her for phase II. Phase I can last several weeks to several months depending on lymphedema severity.
• Phase II, the maintenance phase, begins once the extremity has decongested or plateaued. This phase still focuses on CDT, but now the patient, not the clinician, is responsible for all care. The goal is to reduce limb size while enabling the patient to become self-sufficient in managing lymphedema. Although CDT can bring significant improvements in limb size, skin quality, and function, patients must remember that phase II continues lifelong. Be sure to provide education about ongoing self-management strategies.
Lipedema is a painful disorder of fat deposition. Pathologic deposition of fatty tissue (usually below the waist) leads to progressive leg enlargement. Like lymphedema, lipedema is incurable but manageable. Unless managed properly, lipedema can reduce mobility, interfere with activities of daily living, and lead to secondary lymphedema. (See Lipedema stages.)
Lipedema commonly is misdiagnosed as lymphedema. However, lymphedema involves protein-rich fluid, whereas lip edema is a genetically mediated fat disorder. Because lipedema resists diet and exercise, it can lead to psychosocial complications. Lipedema occurs almost exclusively in women; typically, onset occurs between puberty and age 30. One unpublished epidemiologic study puts lip edema incidence in females at 11%. Some patients have a combination of lipedema and lymphedema. (See Viewing lipolymphedema.)
As with lymphedema, lipedema diagnosis rests on clinical presentation. Lipedema characteristics include bilateral and symmetrical involvement, absence of pitting (because lipedema isn’t a fluid disorder), soft and pliable skin, and filling of the retromalleolar sulcus (called the fat pad sign.)
Key signs and symptoms include:
• feeling of heaviness in the legs (aching dysesthesia)
• easy bruising
• sensitivity to touch (called “painful fat syndrome”)
• orthostatic edema
• oatmeal-like changes to skin texture.
Nearly half of lipedema patients are overweight or obese, but many appear of normal weight from the waist up. Essentially, the upper and lower extremities don’t match. The lower extremities typically show fatty deposits extending from the iliac crest to the ankles, sparing the feet. (See Lipedema patterns.)
Lipedema is best managed through weight control, as additional weight gain through adipose tissue tends to deposit in the legs. For patients with concomitant lymphedema (lipolymphedema), modified CDT helps reduce and manage lymphatic compromise. To address excess fat deposition, newer “wet” liposuction techniques have proven beneficial. These techniques gently detach adipose cells from the tissue, helping to preserve connective tissue and lymphatic vessels.
In both lymphedema and lipedema, early identification and proper diagnosis are key. (See Differentiating lymphedema and lipedema.) A thorough history and physical exam will likely lead to an accurate diagnosis, if clinicians know what to look for. Proper diagnosis and treatment can prevent expensive and ineffective interventions, which can negatively affect both the patient’s condition and psychological well being.
