Limb amputation is a major life-changing event that markedly affects a patient’s quality of life as well as his/her ability to participate in activities of daily living. The most prevalent causes for amputation include vascular diseases, diabetes mellitus, trauma, and cancer, respectively.^1,2 For amputees, maintaining prosthetic use is a major physical and psychological undertaking that benefits from a multidisciplinary team approach. Although individuals with lower limb amputations are disproportionately impacted by skin disease due to the increased mechanical forces exerted over the lower limbs, patients with upper limb amputations also develop dermatologic conditions secondary to wearing prostheses.

Approximately 185,000 amputations occur each year in the United States.³ Although amputations resulting from peripheral vascular disease or diabetes mellitus tend to occur in older individuals, amputations in younger patients usually occur from trauma.² The US military has experienced increasing numbers of amputations from trauma due to the ongoing combat operations in the Middle East. Although improvements in body armor and tactical combat casualty care have reduced the number of preventable deaths, the number of casualties surviving with extremity injuries requiring amputation has increased.^4,5 As of October 2017, 1705 US servicemembers underwent major limb amputations, with 1914 lower limb amputations and 302 upper limb amputations. These amputations mainly impacted men aged 21 to 29 years, but female servicemembers also were affected, and a small group of servicemembers had multiple amputations.⁶

One of the most common medical problems that amputees face during long-term care is skin disease, with approximately 75% of amputees using a lower limb prosthesis experiencing skin problems. In general, amputees experience nearly 65% more dermatologic concerns than the general population.⁷ In one study of 97 individuals with transfemoral amputations, some of the most common issues associated with socket prosthetics included heat and sweating in the prosthetic socket (72%) as well as sores and skin irritation from the socket (62%).⁸ Given the high incidence of skin disease on residual limbs, dermatologists are uniquely positioned to keep the amputee in his/her prosthesis and prevent prosthetic abandonment.

Complications Following Amputation

Although US military servicemembers who undergo amputations receive the very best prosthetic devices and rehabilitation resources, they still experience prosthesis abandonment.⁹ Despite the fact that prosthetic limbs and prosthesis technology have substantially improved over the last 2 decades, one study indicated that the high frequency of problems affecting tissue viability at residual limbs is due to the age-old problem of prosthetic fit.¹⁰ In patients with the most advanced prostheses, poor fit still results in mechanical damage to the skin, as the residual limb is exposed to unequal and shearing forces across the amputation site as well as high pressures that cause a vaso-occlusive effect.^11,12 Issues with poor fit are especially important for more active patients, as they normally want to immediately return to their vigorous preinjury lifestyles. In these patients, even a properly fitting prosthetic may not be able to overcome the fact that the residual limb skin is not well suited for the mechanical forces generated by the prosthesis and the humid environment of the socket.^1,13 Another complicating factor is the dynamic nature of the residual limb. Muscle atrophy, changes in gait, and weight gain or loss can lead to an ill-fitting prosthetic and subsequent skin breakdown.

There are many case reports and review articles describing the skin problems in amputees.^1,14-17 The Table summarizes these conditions and outlines treatment options for each.^15,18-20

Most skin diseases on residual limbs are the result of mechanical skin breakdown, inflammation, infection, or combinations of these processes. Overall, amputees with diabetes mellitus and peripheral vascular disease tend to have skin disease related to poor perfusion, whereas amputees who are active and healthy tend to have conditions related to mechanical stress.^{7,13,14,17,21,22} Bui et al¹⁷ reported ulcers, abscesses, and blisters as the most common skin conditions that occur at the site of residual limbs; however, other less common dermatologic disorders such as skin malignancies, verrucous hyperplasia and carcinoma, granulomatous cutaneous lesions, acroangiodermatitis, and bullous pemphigoid also are seen.^23-26 Buikema and Meyerle¹⁵ hypothesize that these conditions, as well as the more common skin diseases, are partly from the amputation disrupting blood and lymphatic flow in the residual limb, which causes the site to act as an immunocompromised district that induces dysregulation of neuroimmune regulators.

It is important to note that skin disease on residual limbs is not just an acute problem. Long-term follow-up of 247 traumatic amputees from the Vietnam War showed that almost half of prosthesis users (48.2%) reported a skin problem in the preceding year, more than 38 years after the amputation. Additionally, one-quarter of these individuals experienced skin problems approximately 50% of the time, which unfortunately led to limited use or total abandonment of the prosthesis for the preceding year in 56% of the veterans surveyed.²¹

Other complications following amputation indirectly lead to skin problems. Heterotopic ossification, or the formation of bone at extraskeletal sites, has been observed in up to 65% of military amputees from recent operations in Iraq and Afghanistan.^27,28 If symptomatic, heterotopic ossification can lead to poor prosthetic fit and subsequent skin breakdown. As a result, it has been reported that up to 40% of combat-related lower extremity amputations may require excision of heterotopic ossificiation.²⁹

Amputation also can result in psychologic concerns that indirectly affect skin health. A systematic review by Mckechnie and John³⁰ suggested that despite heterogeneity between studies, even using the lowest figures demonstrated the significance anxiety and depression play in the lives of traumatic amputees. If left untreated, these mental health issues can lead to poor residual limb hygiene and prosthetic maintenance due to reductions in the patient’s energy and motivation. Studies have shown that proper hygiene of residual limbs and silicone liners reduces associated skin problems.^19,31

Role of the Dermatologist

Routine care and conservative management of amputee skin problems often are accomplished by prosthetists, primary care physicians, nurses, and physical therapists. In one study, more than 80% of the most common skin problems affecting amputees could be attributed to the prosthesis itself, which highlights the importance of the continued involvement of the prosthetist beyond the initial fitting period.¹³ However, when a skin problem becomes refractory to conservative management, referral to a dermatologist is prudent; therefore, the dermatologist is an integral member of the multidisciplinary team that provides care for amputees.

The dermatologist often is best positioned to diagnose skin diseases that result from wearing prostheses and is well versed in treatments for short-term and long-term management of skin disease on residual limbs. The dermatologist also can offer prophylactic treatments to decrease sweating and hair growth to prevent potential infections and subsequent skin breakdown. Additionally, proper education on self-care has been shown to decrease the amount of skin problems and increase functional status and quality of life for amputees.^32,33 Dermatologists can assist with the patient education process as well as refer amputees to a useful resource from the Amputee Coalition website (www.amputee-coalition.org) to provide specific patient education on how to maintain skin on the residual limb to prevent skin disease.

Current Treatments and Future Directions

Skin disorders affecting residual limbs usually are conditions that dermatologists commonly encounter and are comfortable managing in general practice. Additionally, dermatologists routinely treat hyperhidrosis and conduct laser hair removal, both of which are effective prophylactic adjuncts for amputee skin health. There are a few treatments for reducing residual limb hyperhidrosis that are particularly useful. Although first-line treatment of residual limb hyperhidrosis often is topical aluminum chloride, it requires frequent application and often causes considerable skin irritation when applied to residual limbs. Alternatively, intradermal botulinum toxin has been shown to successfully reduce sweat production in individuals with residual limb hyperhidrosis and is well tolerated.³⁴ A 2017 case report discussed the use of microwave thermal ablation of eccrine coils using a noninvasive 3-step hyperhidrosis treatment system on a bilateral below-the-knee amputee. The authors reported the patient tolerated the procedure well with decreased dermatitis and folliculitis, leading to his ability to wear a prosthetic for longer periods of time.³⁵

Ablative fractional resurfacing with a CO₂ laser is another key treatment modality central to amputees, more specifically to traumatic amputees. A CO₂ laser can decrease skin tension and increase skin mobility associated with traumatic scars as well as decrease skin vulnerability to biofilms present in chronic wounds on residual limbs. It is believed that the pattern of injury caused by ablative fractional lasers disrupts biofilms and stimulates growth factor secretion and collagen remodeling through the concept of photomicrodebridement.³⁶ The ablative fractional resurfacing approach to scar therapy and chronic wound debridement can result in less skin injury, allowing the amputee to continue rehabilitation and return more quickly to prosthetic use.³⁷

One interesting area of research in amputee care involves the study of novel ways to increase the skin’s ability to adapt to mechanical stress and load bearing and accelerate wound healing on the residual limb. Multiple studies have identified collagen fibril enlargement as an important component of skin adaptation, and biomolecules such as decorin may enhance this process.^38-40 The concept of increasing these biomolecules at the correct time during wound healing to strengthen the residual limb tissue currently is being studied.³⁹

Another encouraging area of research is the involvement of fibroblasts in cutaneous wound healing and their role in determining the phenotype of residual limb skin in amputees. The clinical application of autologous fibroblasts is approved by the US Food and Drug Administration for cosmetic use as a filler material and currently is under research for other applications, such as skin regeneration after surgery or manipulating skin characteristics to enhance the durability of residual limbs.⁴¹

Future preventative care of amputee skin may rely on tracking residual limb health before severe tissue injury occurs. For instance, Rink et al⁴² described an approach to monitor residual limb health using noninvasive imaging (eg, hyperspectral imaging, laser speckle imaging) and noninvasive probes that measure oxygenation, perfusion, skin barrier function, and skin hydration to the residual limb. Although these limb surveillance sensors would be employed by prosthetists, the dermatologist, as part of the multispecialty team, also could leverage the data for diagnosis and treatment considerations.

Final Thoughts

The dermatologist is an important member of the multidisciplinary team involved in the care of amputees. Skin disease is prevalent in amputees throughout their lives and often leads to abandonment of prostheses. Although current therapies and preventative treatments are for the most part successful, future research involving advanced technology to monitor skin health, increasing residual limb skin durability at the molecular level, and targeted laser therapies are promising. Through engagement and effective collaboration with the entire multidisciplinary team, dermatologists will have a considerable impact on amputee skin health.

Mild aerobic exercise significantly shortened recovery time from sports-related concussion in adolescent athletes, compared with a stretching program in a randomized trial of 103 participants.

YanLev/ThinkStock

Sports-related concussion (SRC) remains a major public health problem with no effective treatment, wrote John J. Leddy, MD, of the State University of New York at Buffalo, and his colleagues.

Exercise tolerance after SRC has not been well studied. However, given the demonstrated benefits of aerobic exercise training on autonomic nervous system regulation, cerebral blood flow regulation, cardiovascular physiology, and brain neuroplasticity, the researchers hypothesized that exercise at a level that does not exacerbate symptoms might facilitate recovery in concussion patients.

In a study published in JAMA Pediatrics, the researchers randomized 103 adolescent athletes aged 13-18 years to a program of subsymptom aerobic exercise or a placebo stretching program. The participants were enrolled in the study within 10 days of an SRC, and were followed for 30 days or until recovery.

Athletes in the aerobic exercise group recovered in a median of 13 days, compared with 17 days for those in the stretching group (P = .009). Recovery was defined as “symptom resolution to normal,” based on normal physical and neurological examinations, “further confirmed by demonstration of the ability to exercise to exhaustion without exacerbation of symptoms” according to the Buffalo Concussion Treadmill Test, the researchers wrote.

No demographic differences or difference in previous concussions, time from injury until treatment, initial symptom severity score, initial exercise treadmill test, or physical exam were noted between the groups.

The average age of the participants was 15 years, 47% were female. The athletes performed the aerobic exercise or stretching programs approximately 20 minutes per day, and reported their daily symptoms and compliance via a website. The aerobic exercise consisted of walking or jogging on a treadmill or outdoors, or riding a stationary bike while wearing a heart rate monitor to maintain a target heart rate. The target heart rate was calculated as 80% of the heart rate at symptom exacerbation during the Buffalo Concussion Treadmill Test at each participant’s initial visit.

No adverse events related to the exercise intervention were reported, which supports the safety of subsymptom threshhold exercise, in the study population, Dr. Leddy and his associates noted.

The researchers also found lower rates of persistent symptoms at 1 month in the exercise group, compared with the stretching group (two participants vs. seven participants), but this difference was not statistically significant.

The study findings were limited by several factors, including the unblinded design and failure to address the mechanism of action for the effects of exercise. In addition, the results are not generalizable to younger children or other demographic groups, including those with concussions from causes other than sports and adults with heart conditions, the researchers noted.

However, “the results of this study should give clinicians confidence that moderate levels of physical activity, including prescribed subsymptom threshold aerobic exercise, after the first 48 hours following SRC can safely and significantly speed recovery,” Dr. Leddy and his associates concluded.

The study was supported by grants from the National Institutes of Health. The researchers had no financial conflicts to disclose.

Few consumers have heard of the secret, business-to-business payments that the Trump administration wants to ban in an attempt to control drug costs.

But the administration’s plan for drug rebates, announced Jan. 31, would end the pharmaceutical business as usual, shift billions in revenue and cause far-reaching, unforeseen change, say health policy authorities.

In pointed language sure to anger middlemen who benefit from the deals, administration officials proposed banning rebates paid by drug companies to ensure coverage for their products under Medicare and Medicaid plans.

“A shadowy system of kickbacks,” was how Health and Human Services Secretary Alex Azar described the current system in a speech on Feb. 1.

The proposal is a regulatory change applying only to Medicare plans for seniors and managed Medicaid plans for low-income people. But private insurers, who often take cues from government programs, might make a similar shift, administration officials said.

Drug rebates are essentially discounts off the list price. Outlawing them would divert $29 billion in rebates now paid to insurers and pharmacy benefit managers into “seniors’ pocketbooks at the pharmacy counter,” Azar said.

The measure already faces fierce opposition from some in the industry and is unlikely to be implemented as presented or by the proposed 2020 effective date, health policy analysts said.

In any event, it’s hardly a pure win for seniors or patients in general. Consumers are unlikely to collect the full benefit of eliminated rebates.

At the same time, the change would produce uncertain ricochets, including higher drug-plan premiums for consumers, that would produce new winners and losers across the economy.

“It is the most significant proposal that the administration has introduced so far” to try to control drug prices, said Rachel Sachs, a law professor at Washington University in St. Louis. “But I’m struck by the uncertainty that the administration has in what the effects would be.”
 

Chronically ill patients who take lots of expensive medicine

The list price for many brand-name medicines has doubled or tripled in recent years. But virtually the only ones affected by the full increases are the many patients who pay cash or whose out-of-pocket payments are based on the posted price.

By banning rebates, the administration says its intention is to ensure discounts are passed all the way to the patient instead of the middlemen, the so-called pharmacy benefit managers or PBMs. That means consumers using expensive drugs might see their out-of-pocket costs go down.

If rebates were eliminated for commercial insurance, where deductibles and out-of-pocket costs are generally much higher, chronically ill patients could benefit much more.
 

Drug companies

Ending rebates would give the administration a drug-policy “win” that doesn’t directly threaten pharmaceutical company profits.

“We applaud the administration for taking steps to reform the rebate system” Stephen Ubl, CEO of PhRMA, the main lobby for branded drugs, said after the proposal came out.

The change might also slow the soaring list-price increases that have become a publicity nightmare for the industry. When list prices pop by 5% or 10% each year, drugmakers pay part of the proceeds to insurers and PBMs in the form of rebates to guarantee health-plan coverage.

No one is claiming that eliminating rebates would stop escalating list prices, even if all insurers adopted the practice. But some believe it would remove an important factor.
 

Pharmacy benefit managers

PBMs reap billions of dollars in rebate revenue in return for putting particular products on lists of covered drugs. The administration is essentially proposing to make those payments illegal, at least for Medicare and Medicaid plans.

PBMs, which claim they control costs by negotiating with drugmakers, might have to go back to their roots – processing pharmacy claims for a fee. After recent industry consolidation into a few enormous companies, on the other hand, they might have the market power to charge very high fees, replacing much of the lost rebate revenue.

PBMs “are concerned” that the move “would increase drug costs and force Medicare beneficiaries to pay higher premiums and out-of-pocket expenses,” said JC Scott, CEO of the Pharmaceutical Care Management Association, the PBM lobby.
 

Insurance companies

Insurers, who often receive rebates directly, could also be hurt financially.

“From the start, the focus on rebates has been a distraction from the real issue – the problem is the price” of the drugs, said Matt Eyles, CEO of America’s Health Insurance Plans, a trade group. “We are not middlemen – we are your bargaining power, working hard to negotiate lower prices.”
 

Patients without chronic conditions and high drug costs

Lower out-of-pocket costs at the pharmacy counter would be financed, at least in part, by higher premiums for Medicare and Medicaid plans paid by consumers and the government. Premiums for Medicare Part D plans could rise from $3.20 to $5.64 per month, according to consultants hired by the Department of Health and Human Services.

“There is likely to be a wide variation in how much savings people see based on the drugs they take and the point-of-sale discounts that are negotiated,” said Elizabeth Carpenter, policy practice director at Avalere, a consultancy.

Consumers who don’t need expensive drugs every month could see insurance costs go up slightly without getting the benefits of lower out-of-pocket expense for purchased drugs.

Other policy changes giving health plans more negotiating power against drugmakers would keep a lid on premium increases, administration officials argue.

The clinical relevance of tamoxifen pharmacogenetics and therapeutic drug monitoring has been challenged, according to findings from an observational study.

“The objective of the prospective CYPTAM study was to associate endoxifen concentrations and CYP2D6 genotypes with clinical outcome[s] in patients with early-stage breast cancer receiving tamoxifen,” wrote Anabel Sanchez-Spitman, PharmD, of the Leiden University Medical Center, the Netherlands, and her colleagues in the Journal of Clinical Oncology.

“Although, in a retrospective study, an endoxifen threshold of 5.9 ng/mL for efficacy [has been] described, confirmation based on prospective studies is lacking,” they wrote.

The researchers followed 667 patients with early-stage breast malignancy who were treated with 20 mg of oral tamoxifen daily.

Dr. Sanchez-Spitman and her colleagues performed CYP2D6 genotype testing and measured blood levels of endoxifen, an active metabolite of tamoxifen, in study participants. Both of these measures were linked with relapse-free survival via statistical analysis.

After analysis, no significant association was found between endoxifen concentrations (P = .691) or CYP2D6 genotyping (P = .799) and relapse-free survival. These data were the same in both univariable and multivariable regression analysis.

“Neither categorizing endoxifen concentrations into quartiles nor using 5.9 ng/mL as threshold altered these results,” they wrote.

The authors acknowledged that a key limitation of the study was the absence of tamoxifen adherence testing, but the availability of persistence data was well collected, lessening this drawback.

“Our data do not justify therapeutic drug monitoring based on endoxifen concentrations in patients with breast cancer receiving tamoxifen,” they concluded.

The study was supported by grant funding provided by ZOLEON. The authors reported no conflicts of interest.

Aerobic exercise significantly improves executive function among adults with below-average fitness. Also today, findings in seropositive arthralgia patients may help to predict rheumatoid arthritis, elevated coronary artery calcification is not linked to increased death risk in active men, and clinical benefits persist 5 years after theymectomy for myasthenia gravis.

What makes us pull a hand away from a hot stove or flinch at a pinprick? Researchers from the National Center for Complementary and Integrative Health say they have identified activity in the brain that governs these reactions.

Alexander Chesler, PhD, senior author of the study, says we already know a lot about local spinal cord circuits for simple reflexive responses, but “the mechanisms underlying more complex behaviors remain poorly understood.”

Using heat as the source of discomfort in their experiments, the researchers found a predictable sequence of behaviors—likened to the sequence of responding to walking cautiously on a hot beach, then hopping as the heat intensifies, then running to a water source. “This kind of ‘feed-forward’ circuitry is unique because it is an upward spiral,” says Arnab Barik, PhD, one of the study authors. “The more this pathway is activated by harmful activity, the more it reacts, leading to dramatic behavioral responses.”

The experiments showed that the parts of the brainstem involved in this circuit are the parabrachial nucleus (PBNI) and the dorsal reticular formation in the medulla (MdD). Standing on a hot surface activated a group of nerve cells in the PBNI, triggering escape responses through connections to the MdD. Interestingly, the PBNI cells express a gene that codes for substances that also contribute to multiple disease processes.

“Our data provide evidence that the PBNI produces streams of information with distinct functional significance,” says Arnab Barik, PhD, one of the study authors. “The brainstem-spinal cord pathway identified in this study selectively controls pain response and elicits appropriate behaviors based on sensory input.”

Further investigation, the researchers say, can help us understand how pain is encoded in the brain. The study findings may also offer opportunities to understand how the body becomes dysregulated during chronic pain.

The incidence of obesity-related cancers such as kidney and gallbladder cancer has increased significantly in young adults over the past two decades in the United States, according to an analysis of data from 25 population-based state registries in the United States.

The incidence of 6 of the 12 obesity-related cancers increased among individuals aged 25-49 years, Hyuna Sung, PhD, of the American Cancer Society, Atlanta, and her colleagues reported Feb. 4 in the Lancet Public Health.

World Obesity Federation

Among more than 14.6 million incident cases of cancer diagnosed in adults aged 25-84 years between 1995 and 2014, the greatest increase in incidence, 6.23% annually, was seen with kidney cancer among the 25- to 29-year age group. Incidence, however, also increased by at least 6.17% in those aged 30-34 years, by 5.23% in those aged 35-39 years, and by 3.88% in those aged 40-44 years.

The incidence rate for kidney cancer among individuals born around 1985 was nearly fivefold higher than in individuals born in 1950, the investigators said (Lancet Public Health. 2019 Feb 4. doi: 10.1016/S2468-2667(18)30267-6).

The analysis also showed significant increases from 1995 to 2014 in the incidence of cancer of the gallbladder among younger adults: 3.71% per year among those aged 25-29 years and 2.58% per year in those aged 30-34 years.

Similarly, the incidence of uterine corpus cancer increased in the 25- to 29-year age group by 3.34% per year and by 3.22% in the 30- to 34-year age group. The incidence of colorectal cancer increased by 2.41% among those aged 25-29 years and by 2.38% in those aged 30-34 years, Dr. Sung and her associates said.

The greatest annual increase in the incidence of multiple myeloma was seen in individuals aged 30-34 years (2.21%), but significant annual increases in incidence were seen in individuals aged 30-44 years.
