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…)

It’s necessary for the skin to heal the wounds after getting injured. For the first time, scientists discovered that the changing stem cell dynamics contribute to wound healing. The main purpose of these studies was to understand how stem cells differentiate, migrate, and proliferate to repair the tissue damage after trauma.
A team from Université libre de Bruxelles (ULB) started their research on stem cells. Professor of ULB, Dr. Cédric Blanpain MD/Ph.D, WELBIO investigator and the lead researcher of this study, defined the cellular and molecular mechanisms that play active roles in wound healing. The research report was first published in the Journal of Nature Communications.
The skin of a creature is just like an outer shield which protects the inner tissues and other organs from outer injuries. If somehow the outer shield gets disrupted then body activates a cascade of cellular and molecular event to repair the damage and restore skin integrity. ScienceDaily reported that minor defects in these events lead to improper repair causing acute and chronic wound disorders.
In the new study, scientists revealed that distinct stem cells populations contribute in healing the wound. Although it is not cleared yet how proliferation, differentiation, and migration get balanced by stem cell populations during the healing process. Co-author of this study Dr.Sophie Dekoninck said in a statement,“The molecular characterization of the migrating leading edge suggests that these cells are protecting the stem cells from the infection and mechanical stress allowing a harmonious healing process”.
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…)

I recently visited an 83-year-old patient in the hospital after EMTs rushed her to the ER with an infected leg wound. Her ordeal started inconspicuously when she bumped into the sharp edge of a table and developed a small cut. The patient’s wound didn’t close, but she ignored it until she woke up in pain one morning two weeks after first injuring her leg. Her daughter called 911 after noticing angry, red skin discoloration and pus – both signs of an infection. Our medical team treated her with IV antibiotics and cleared up the infection, but the wound did not fully close until at least a month later, well after she was discharged from the hospital.
How different the story is when children get a cut. They may scream initially, but within days, the scab falls off, revealing new skin. Why was healing so delayed in my 83-year-old patient compared to a healthy child?
The answer is age. Decades of life slow down healing for most tissues, and wounds in skin can offer a window into why this slowdown occurs.
Three stages of wound healing
I am physician who studies how aging predisposes patients to diseases like diabetes and whether behavioral changes such as intermittent fasting may slow down aging. In order to understand why the skin wound in my older patient healed so slowly, it is important to first understand how wounds heal under the ideal conditions of youth.
The first stage is inflammation, essentially the body’s attempt to clean the wound. During the inflammatory phase, immune cells called phagocytes move into the wound, kill any contaminating bacteria, and ingest and dispose of dead cells and debris.
Inflammation sets the stage for the regenerative phase, where several processes work in concert to regrow damaged skin. Replacement skin cells are born when cells at the edge of the wound divide, while fibroblast cells lay down a supportive scaffolding called the extracellular matrix. This holds the new cells together. Any damaged supporting structures of the skin, such as the blood vessels that supply critical oxygen and nutrients, also need to regrow. The second stage effectively closes the wound and restores a protective barrier against bacteria.

The regenerative phase is a relatively quick, but tenuous fix – new skin is fragile. The final remodeling phase plays out over a couple of years as the new skin is progressively strengthened by several parallel processes. The extracellular matrix, which was initially laid down in a haphazard fashion, is broken down and replaced in a more durable way. Any residual cells from prior phases that are no longer needed – such as immune cells or fibroblasts – become inactive or die. In addition to strengthening the new skin, these collective actions also account for the tendency of scars to visibly fade with time.
One major way aging can derail the orderly and efficient progression through the stages of healing is through the health problems that stem from diseases of old age.
Diabetes is one example of a disease that is strongly associated with older age. One of the many ways that diabetes negatively affects healing is by causing blood vessels to narrow. As a consequence of inadequate circulation, crucial nutrients and oxygen do not reach the wound in sufficient quantities to fuel the second regenerative phase.
Diabetes is just one of many age-related diseases that disrupts normal processes in the body such as wound healing.
When cells divide more slowly – or when they stop dividing altogether due to senescence – skin becomes thinner. The replacement of fat cells, which form a cushioning layer under the skin, also declines with age. The skin of older patients is therefore more prone to injury in the first place.
Once an older person’s skin is injured, the skin has a harder time healing properly as well. Aging and senescent immune cells cannot defend against bacteria, and the risk of serious skin infection rises. Then in the regenerative stage, slow rates of cell division translate into slow skin regrowth. My patient exhibited all of these negative effects of age – her thin, almost translucent skin ruptured from a minor bump, became infected and took nearly two months to fully regrow.
But senescent cells are more than just dysfunctional bystanders. For reasons that are not yet fully understood, senescent cells release toxic byproducts that damage surrounding tissue and drive inflammation – even when there’s no bacterial threat present. Some of these byproducts can even accelerate senescence in neighboring cells. This suggests that intrinsic aging of cells is in essence contagious and senescent cells actively fuel an uncontrolled cycle of inflammation and tissue damage that further impedes successful regeneration and healing.
A whole body problem
As the most outwardly visible tissue of the body, the skin provides a window into why people heal more slowly with age, but all tissues can be injured and are susceptible to the effects of aging. Injuries may be small, repetitive and build up over time – like the effect of smoking on the lungs. Or they may be discrete and dramatic – such as the death of heart cells with a heart attack. Different tissues may heal in different ways. Yet all tissues share a sensitivity to the repercussions of an aging immune system and a decline in the ability to regrow dead or damaged cells.
Understanding why healing slows down with age is important, but my patient asked a very practical question that physicians often face in one form or another: “Doctor, what can you do for me?”
Unfortunately, current treatment of wounds is fairly old-fashioned and often ineffective. Some of the options available include wound dressing changes, antibiotics when the wound is infected or treatment in a high oxygen chamber when circulation is bad due to diabetes.
There is hope, though, that medicine can do better and that progress in understanding the aging process will lead to new therapies. Neutralizing senescent cells in mice, for example, improves a variety of age-associated diseases. While it is way too early to say that researchers have discovered the fountain of youth, I am optimistic for a future when physicians will bend the aging curve and make skin and other organs heal faster and better.
Debbie King barely gave it a second thought when she scraped her right shin climbing onto her friend’s pontoon for a day of boating in the Gulf of Mexico on Aug. 13.
Even though her friend immediately dressed the slight cut, her shin was red and sore when King awoke the next day. It must be a sunburn, she thought.
But three days later, the red and blistered area had grown. Her doctor took one look and sent King, 72, to the emergency room.
Doctors at HCA Florida Citrus Hospital in Inverness, Florida, rushed King into surgery after recognizing the infection as Vibrio vulnificus, a potentially fatal bacterium that kills healthy tissue around a wound. While King lay on the operating table, the surgeon told her husband she would likely die if they didn’t amputate.
Just four days after the scrape, King lost her leg then spent four days in intensive care.
“The flesh was gone; it was just bone,” she said of her leg.
Cases of V. vulnificus are rare. Between 150 and 200 are reported to the Centers for Disease Control and Prevention every year, with about 20% resulting in death. Most are in states along the Gulf of Mexico, but, in 2019, 7% were on the Pacific Coast. Florida averages about 37 cases and 10 deaths a year.
But a rise in cases nationally and the spread of the disease to states farther north — into coastal communities in states such as Connecticut, New York, and North Carolina — have heightened concerns about the bacterium, which can result in amputations or extensive removal of tissue even in those who survive its infections. And warmer coastal waters caused by climate change, combined with a growing population of older adults, may result in infections doubling by 2060, a study in Scientific Reports warned earlier this year.
“Vibrio distributions are driven in large part by temperature,” said Tracy Mincer, an assistant professor at Florida Atlantic University. “The warmer waters are, the more favorable it is for them.”
The eastern United States has seen an eightfold increase in infections over a 30-year period through 2018 as the geographic range of infections shifted north by about 30 miles a year, according to the study, which was cited in a CDC health advisory last month.
The advisory was intended to make doctors more aware of the bacterium when treating infected wounds exposed to coastal waters. Infections can also arise from eating raw or undercooked seafood, particularly oysters, it warned. That can cause symptoms as common as diarrhea and as serious as bloodstream infections and severe blistered skin lesions.
New York and Connecticut this summer issued health warnings about the risk of infection as well. It’s not the first year either state has recorded cases.
“There’s very few cases but when they happen, they’re devastating,” said Paul A. Gulig, a professor in the Department of Molecular Genetics and Microbiology at the University of Florida College of Medicine.
‘An Accident of Nature’
Vibrio has more than 100 strains, including the bacterium that causes cholera, a disease that causes tens of thousands of deaths worldwide each year.
The V. vulnificus strain likes warm brackish waters close to shorelines where the salinity is not as high as in the open sea. Unlike some other Vibrio strains, it has no mechanism to spread between humans.
It’s found in oysters because the mollusks feed by filtering water, meaning the bacterium can become concentrated in oyster flesh. It can enter humans who swim in salty or brackish waters through the slightest cut in the skin. Infections are treated with antibiotics and, if needed, surgery.
“It’s almost an accident of nature,” Gulig said. “They have all these virulence factors that make them really destructive, but we’re not a part of this bug’s life cycle.”
Once inside the human body, the bacteria thrive.
Scientists don’t believe the bacteria eat flesh, despite how they’re often described. Rather, enzymes and toxins secreted by the bacterium as it multiplies break down the human tissue in the area below the skin, causing necrosis, or death of tissue cells.
The infection spreads like wildfire, Gulig said, making early detection critical.
“If you take a pen and mark where the edge of the redness is and then look at that two or four hours later, the redness would have moved,” Gulig said. “You can almost sit there and watch this spread.”
Researchers have conducted studies on the bacteria, but the small number of cases and deaths make it tough to secure funding, said Gulig. He said he switched his research focus to other areas because of the lack of money.
But growing interest in the bacteria has prompted talk about new research at his university’s Emerging Pathogens Institute.
Examining the bacteria’s genome sequence and comparing it with those of Vibrio strains that don’t attack human flesh could yield insights into potential drugs to interfere with that process, Gulig said.
Shock and Loss
Inside the operating room at HCA Florida Citrus, the only signs of King’s infection were on her shin. The surgeon opened that area and began cutting away a bright red mush of dead flesh.
Hoping to save as much of the leg as possible, the doctor first amputated below her knee.
But the bacteria had spread farther than doctors had hoped. A second amputation, this time 5 inches above the knee, had to be performed.
After surgery, King remained in critical care for four days with sepsis, a reaction to infection that can cause organs to fail.
Her son was there when she awakened. He was the one who told her she had lost her leg, but she was too woozy from medication to take it in.
It wasn’t until she was transferred to a rehab hospital in nearby Brooksville run by Encompass Health that the loss sank in.
A former radiation protection technician, King had always been self-reliant. The idea of needing a wheelchair, of being dependent on others — it felt like she had lost part of her identity.
One morning, she could just not stop crying. “It hit me like a ton of bricks,” she said.
Six different rehab staffers told her she needed to meet with the hospital’s consulting psychologist. She thought she didn’t need help, but she eventually gave in and met with Gerald Todoroff.
In four sessions with King, he said, he worked to redirect her perception of what happened. Amputation is not who you are but what you will learn to deal with, he told her. Your life can be as full as you wish.
“They were magic words that made me feel like a new person,” King said. “They went through me like music.”
Physical therapy moved her forward, too. She learned how to stand longer on her remaining leg, to use her wheelchair, and to maneuver in and out of a car.
Now, back in her Gulf Coast community of Homosassa, those skills have become routine. Her husband, Jim, a former oil company worker and carpenter, built an access ramp out of concrete and pressure-treated wood for their single-story home.
But she is determined to walk with the aid of a prosthetic leg. It’s the motivation for a one-hour regimen of physical therapy she does on her own every day in addition to twice-weekly sessions with a physical therapist.
Recovery still feels like a journey but one marked by progress. She has nicknamed her “stump” Peg. She’s now comfortable sharing before and after pictures of her leg.
And she’s made it her mission to talk about what happened so more people will learn about the danger.
“This is the most horrific thing that can happen to anybody,” she said. “But I’d sit back and think, ‘God put you here for a reason — you’ve got more things to do.’”
What to Know About ‘Flesh-Eating’ Bacterium Vibrio vulnificus
Infection Symptoms:
Diarrhea, often accompanied by stomach cramping, nausea, vomiting, and fever.
Wound infections cause redness, pain, swelling, warmth, discoloration, and discharge. They may spread to the rest of the body and cause fever.
Bloodstream infections cause fever, chills, dangerously low blood pressure, and blistering skin lesions.
To Protect Against Vibrio Infections:
Stay out of saltwater or brackish water if you have a wound or a recent surgery, piercing, or tattoo.
Cover wounds with a waterproof bandage if they could come into contact with seawater or raw or undercooked seafood and its juices.
Wash wounds and cuts thoroughly with soap and water after contact with saltwater, brackish water, raw seafood, or its juices.
Who Is Most at Risk:
Anyone can get a wound infection. People with liver disease, cancer, or diabetes, and those over 40 or with weakened immune systems, are more likely to get an infection and have severe complications.

Why All the (pH)uss About Microenvironments?
The Importance of Acidic pH on Wound Healing Why All the (pH)uss About Microenvironments? By Martha Kelso, RN, HBOT, CEO, WCP The Wound Microenvironment Every wound or ulcer has factors that influence the wound bed environment and how it reacts. Many of these factors occur at a microscopic level and therefore can be referred to as the wound microenvironment. Inside this microenvironment, factors are at play that influence whether a wound heals or becomes chronically stalled.
