Frequently asked questions about support surfaces

The National Pressure Ulcer Advisory Panel (NPUAP) describes support surfaces as “specialized devices for pressure redistribution designed for management of tissue loads, microclimate, and/or other therapeutic functions.” These devices include specialized mattresses, mattress overlays, chair cushions, and pads used on transport stretchers, operating room (OR) tables, examination or procedure tables, and gurneys. Some support surfaces are part of an integrated bed system, which combines the bed frame and support surface into a single unit. (more…)

Leprosy cases are rising in the US – what is the ancient disease and why is it spreading now?

leprosy

By Robert A. Schwartz, Rutgers University

The word “leprosy” conjures images of biblical plagues, but the disease is still with us today. Caused by infectious bacteria, some 200,000 new cases are reported each year, according to the World Health Organization. In the United States, leprosy has been entrenched for more than a century in parts of the South where people came into contact with armadillos, the principle proven linkage from animal to humans. However, the more recent outbreaks in the Southeast, especially Florida, have not been associated with animal exposure.

The Conversation talked with Robert A. Schwartz, professor and head of dermatology at Rutgers New Jersey Medical School, to explain what researchers know about the disease.

What is leprosy and why is it resurfacing in the US?

Leprosy is caused by two different but similar bacteria — Mycobacterium leprae and Mycobacterium lepromatosis — the latter having just been identified in 2008. Leprosy, also known as Hansen’s disease, is avoidable. Transmission among the most vulnerable in society, including migrant and impoverished populations, remains a pressing issue.

This age-old neglected tropical disease, which is still present in more than 120 countries, is now a growing challenge in parts of North America.

Leprosy is beginning to occur regularly within parts of the southeastern United States. Most recently, Florida has seen a heightened incidence of leprosy, accounting for many of the newly diagnosed cases in the U.S.

The surge in new cases in central Florida highlights the urgent need for health care providers to report them immediately. Contact tracing is critical to identifying sources and reducing transmission.

Traditional risk factors include zoonotic exposure and having recently lived in leprosy-endemic countries. Brazil, India and Indonesia have each noted more than 10,000 new cases since 2019, according to the World Health Organization data, and more than a dozen countries have reported between 1,000 to 10,000 new cases over the same time period.

Why was leprosy stigmatized in biblical times?

Evidence suggests that leprosy has plagued civilization since at least the second millennium B.C.

From that time until the mid-20th century, limited treatments were available, so the bacteria could infiltrate the body and cause prominent physical deformities such as disfigured hands and feet. Advanced cases of leprosy cause facial features resembling that of a lion in humans.

Many mutilating and distressing skin disorders such as skin cancers and deep fungal infections were also confused with leprosy by the general public.

Fear of contagion has led to tremendous stigmatization and social exclusion. It was such a serious concern that the Kingdom of Jerusalem had a specialized hospital to care for those suffering from leprosy.

How infectious is leprosy?

Research shows that prolonged in-person contact via respiratory droplets is the primary mode of transmission, rather than through normal, everyday contact such as embracing, shaking hands or sitting near a person with leprosy. People with leprosy generally do not transmit the disease once they begin treatment.

Armadillos represent the only known zoonotic reservoir of leprosy-causing bacteria that threaten humans. These small mammals are common in Central and South America and in parts of Texas, Louisiana, Missouri and other states, where they are sometimes kept as pets or farmed as meat. Eating armadillo meat is not a clear cause of leprosy, but capturing and raising armadillos, along with preparing its meat, are risk factors.

The transmission mechanism between zoonotic reservoirs and susceptible individuals is unknown, but it is strongly suspected that direct contact with an infected armadillo poses a significant risk of developing leprosy. However, many cases reported in the U.S. have demonstrated an absence of either zoonotic exposure or person-to-person transmission outside of North America, suggesting that transmission may be happening where the infected person lives. But in many cases, the source remains an enigma.

Some people’s genetics might make them more susceptible to leprosy infections, or their immune systems are less capable of resisting the disease.

Stigma and discrimination have prevented people from seeking treatment, and as a result, “concealed” cases contribute to transmission.

How do you recognize it?

Leprosy primarily affects the skin and peripheral nervous system, causing physical deformity and desensitizing one’s ability to feel pain on affected skin.

It may begin with loss of sensation on whitish patches of skin or reddened skin. As the bacteria spread in the skin, they can cause the skin to thicken with or without nodules. If this occurs on a person’s face, it may rarely produce a smooth, attractive-appearing facial contour known as lepra bonita, or “pretty leprosy.” The disease can progress to causing eyebrow loss, enlarged nerves in the neck, nasal deformities and nerve damage.

The onset of symptoms can sometimes take as long as 20 years because the infectious bacteria have a lengthy incubation period and proliferate slowly in the human body. So presumably many people are infected long before they know that they are.

Fortunately, worldwide efforts to screen for leprosy are being enhanced thanks to organizations like the Order of Saint Lazarus, which was originally founded in the 11th century to combat leprosy, and the Armauer Hansen Research Institute, which conducts immunologic, epidemiological and translational research in Ethiopia. The nongovernmental organization Bombay Leprosy Project in India does the same.

How treatable is it?

Leprosy is not only preventable but treatable. Defying stigma and advancing early diagnosis via proactive measures are critical to the mission of controlling and eradicating it worldwide.

Notably, the World Health Organization and other agencies provide multi-drug therapy at no cost to patients.

In addition, vaccine technology to combat leprosy is in the clinical trials stage and could become available in coming years. In studies involving nine-banded armadillos, this protein-based vaccine delayed or diminished leprous nerve damage and kept bacteria at bay. Researchers believe that the vaccine can be produced in a low-cost, highly efficient manner, with the long-term prospect of eradicating leprosy.

If health care professionals, biomedical researchers and lawmakers do not markedly enhance their efforts to eliminate leprosy worldwide, the disease will continue to spread and could become a far more serious problem in areas that have been largely free of leprosy for decades.

Rare ‘Flesh-Eating’ Bacterium Spreads North as Oceans Warm

Map of cases of the flesh eating bacteria Vibrio vulnificus

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.

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.

Scientists Seek People with Primary Progressive MS and Other Forms of MS to Study Gut Bacteria

Volunteers are being sought for a major study to help determine how the gut microbiome can be used to treat multiple sclerosis, lupus, and other diseases.

Investigators at the University of California in San Francisco are recruiting people with MS for an international study of the gut microbiome – the population of bacteria in the gut – in MS. They are seeking people with primary progressive MS nationwide (there is no need for onsite visits), as well as people with any other type of MS who can make a one-time visit to San Francisco, New York, Boston or Pittsburgh. The overall purpose of these studies is to investigate the potential role of gut bacteria in MS.

Nurses, Doctors and Hospitals use Google Glass

nurses doctors hospitals use google glass

For surgical collaboration; rural telemedicine, nurses and doctors at Hospitals use Google Glass. Indianapolis-based Hodei Technology is bringing Glass to hospitals in two different ways: as a tool for surgeons to teach, communicate, and collaborate (via a product called Ikasi) and, via a product called Gemini, as a new kind of telemedicine, which CEO Guy Mascaro describes as “first person point-of-view telepresence”.

A lot of people think Google Glass, the tech company’s experiment with augmented reality and wearable computing, died when the Glass Explorer program closed up shop in 2015. In fact, the technology has continued to find a home with enterprise applications, particularly in healthcare. (more…)

Compression Sock for Excessive Sitting or Standing

Helping Patients with Lymphedema

Success as an HME compression provider takes commitment, education and an understanding that there is more to compression beyond the feet.

The compression sock is an integral product to carry for any HME provider committed to using compression technology to help patients. Compression doesn’t even need to be required due a medical condition – it’s an almost universal need. Sitting or standing for excessive amounts of time can be terrible for your health, especially the feet. For example, sitting with your legs crossed beneath your chair can cause pressure that results in swollen ankles or varicose veins. And standing all day at work can cause issues from your neck all the way to your feet. (more…)

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.
