Spinal cord stimulator restores Parkinson patient’s gait
The neuroprosthesis involves targeted epidural electrical stimulation of areas of the lumbosacral spinal cord that produce walking.
This new therapeutic tool offers hope to patients with PD and, combined with existing approaches, may alleviate a motor sign in PD for which there is currently “no real solution,” study investigator Eduardo Martin Moraud, PhD, who leads PD research at the Defitech Center for Interventional Neurotherapies (NeuroRestore), Lausanne, Switzerland, said in an interview.
“This is exciting for the many patients that develop gait deficits and experience frequent falls, who can only rely on physical therapy to try and minimize the consequences,” he added.
The findings were published online in Nature Medicine.
Personalized stimulation
About 90% of people with advanced PD experience gait and balance problems or freezing-of-gait episodes. These locomotor deficits typically don’t respond well to dopamine replacement therapy or deep brain stimulation (DBS) of the subthalamic nucleus, possibly because the neural origins of these motor problems involve brain circuits not related to dopamine, said Dr. Moraud.
Continuous electrical stimulation over the cervical or thoracic segments of the spinal cord reduces locomotor deficits in some people with PD, but the broader application of this strategy has led to variable and unsatisfying outcomes.
The new approach focuses on correcting abnormal activation of circuits in the lumbar spinal cord, a region that hosts all the neurons that control activation of the leg muscles used for walking.
The stimulating device is placed on the lumbar region of the spinal cord, which sends messages to leg muscles. It is wired to a small impulse generator implanted under the skin of the abdomen. Sensors placed in shoes align the stimulation to the patient’s movement.
The system can detect the beginning of a movement, immediately activate the appropriate electrode, and so facilitate the necessary movement, be that leg flexion, extension, or propulsion, said Dr. Moraud. “This allows for increased walking symmetry, reinforced balance, and increased length of steps.”
The concept of this neuroprosthesis is similar to that used to allow patients with a spinal cord injury (SCI) to walk. But unlike patients with SCI, those with PD can move their legs, indicating that there is a descending command from the brain that needs to interact with the stimulation of the spinal cord, and patients with PD can feel the stimulation.
“Both these elements imply that amplitudes of stimulation need to be much lower in PD than SCI, and that stimulation needs to be fully personalized in PD to synergistically interact with the descending commands from the brain.”
After fine-tuning this new neuroprosthesis in animal models, researchers implanted the device in a 62-year-old man with a 30-year history of PD who presented with severe gait impairments, including marked gait asymmetry, reduced stride length, and balance problems.
Gait restored to near normal
The patient had frequent freezing-of-gait episodes when turning and passing through narrow paths, which led to multiple falls a day. This was despite being treated with DBS and dopaminergic replacement therapies.
But after getting used to the neuroprosthesis, the patient now walks with a gait akin to that of people without PD.
“Our experience in the preclinical animal models and this first patient is that gait can be restored to an almost healthy level, but this, of course, may vary across patients, depending on the severity of their disease progression, and their other motor deficits,” said Dr. Moraud.
When the neuroprosthesis is turned on, freezing of gait nearly vanishes, both with and without DBS.
In addition, the neuroprosthesis augmented the impact of the patient’s rehabilitation program, which involved a variety of regular exercises, including walking on basic and complex terrains, navigating outdoors in community settings, balance training, and basic physical therapy.
Frequent use of the neuroprosthesis during gait rehabilitation also translated into “highly improved” quality of life as reported by the patient (and his wife), said Dr. Moraud.
The patient has now been using the neuroprosthesis about 8 hours a day for nearly 2 years, only switching it off when sitting for long periods of time or while sleeping.
“He regained the capacity to walk in complex or crowded environments such as shops, airports, or his own home, without falling,” said Dr. Moraud. “He went from falling five to six times per day to one or two [falls] every couple of weeks. He’s also much more confident. He can walk for many miles, run, and go on holidays, without the constant fear of falling and having related injuries.”
Dr. Moraud stressed that the device does not replace DBS, which is a “key therapy” that addresses other deficits in PD, such as rigidity or slowness of movement. “What we propose here is a fully complementary approach for the gait problems that are not well addressed by DBS.”
One of the next steps will be to evaluate the efficacy of this approach across a wider spectrum of patient profiles to fully define the best responders, said Dr. Moraud.
A ‘tour de force’
In a comment, Michael S. Okun, MD, director of the Norman Fixel Institute for Neurological Diseases, University of Florida, Gainesville, and medical director of the Parkinson’s Foundation, noted that the researchers used “a smarter device” than past approaches that failed to adequately address progressive walking challenges of patients with PD.
Although it’s “tempting to get excited” about the findings, it’s important to consider that the study included only one human subject and did not target circuits for both walking and balance, said Dr. Okun. “It’s possible that even if future studies revealed a benefit for walking, the device may or may not address falling.”
In an accompanying editorial, Aviv Mizrahi-Kliger, MD, PhD, department of neurology, University of California, San Francisco, and Karunesh Ganguly, MD, PhD, Neurology and Rehabilitation Service, San Francisco Veterans Affairs Health Care System, called the study an “impressive tour de force,” with data from the nonhuman primate model and the individual with PD “jointly” indicating that epidural electrical stimulation (EES) “is a very promising treatment for several aspects of gait, posture and balance impairments in PD.”
But although the effect in the single patient “is quite impressive,” the “next crucial step” is to test this approach in a larger cohort of patients, they said.
They noted the nonhuman model does not exhibit freezing of gait, “which precluded the ability to corroborate or further study the role of EES in alleviating this symptom of PD in an animal model.”
In addition, stimulation parameters in the patient with PD “had to rely on estimated normal activity patterns, owing to the inability to measure pre-disease patterns at the individual level,” they wrote.
The study received funding from the Defitech Foundation, ONWARD Medical, CAMS Innovation Fund for Medical Sciences, National Natural Science Foundation of China, Parkinson Schweiz Foundation, European Community’s Seventh Framework Program (NeuWalk), European Research Council, Wyss Center for Bio and Neuroengineering, Bertarelli Foundation, and Swiss National Science Foundation. Dr. Moraud and other study authors hold various patents or applications in relation to the present work. Dr. Mizrahi-Kliger has no relevant conflicts of interest; Dr. Ganguly has a patent for modulation of sensory inputs to improve motor recovery from stroke and has been a consultant to Cala Health.

FROM NATURE MEDICINE
Does laughter offer better blood glucose control?
David S. Greene, PhD, associate professor in the department of rehabilitation and human services at the University of Northern Colorado, Greeley, has pioneered research into the field, one previously overlooked when it comes to diabetes management.
This news organization caught up with Dr. Greene to ask about his research along with the implications for diabetes care and for patient well-being.
Question: What prompted you to research the link between humor and diabetes control?
Answer: I was diagnosed with type 1 diabetes in 1966 and consequently have lived with, and studied, various aspects of diabetes for the past 57 years.
For a time, I maintained a small private practice counseling people with diabetes. There I noticed, anecdotally, that my clients’ ability to laugh at, and see the humor in, their diabetes correlated with their emotional adjustment to living with their condition.
While I could find research confirming the physical and psychological benefits of humor in general, I was unable to find any research specifically relating to humor and diabetes.
My new research agenda was born.
Q: What did your research reveal?
A: My first study, published in 2020, found that people living with diabetes displayed the same level of both types of positive, or affiliative and self-enhancing, humor as the norm group used in developing the Humor Styles Questionnaire.
This was a surprising finding given that individuals with diabetes are dealing with a life-altering, chronic illness, with higher rates of depression and anxiety. Moreover, positive humor scores are known to be negatively correlated with depression and anxiety.
While levels of aggressive humor were not altered in my study, people with diabetes did have higher levels of self-defeating humor in my study, which is correlated with psychiatric and somatic concerns, and symptomatology, and so is to be expected.
My second study, published in 2021, examined whether there was a difference between people with diabetes who had an hemoglobin A1c level of 6.99% or less versus those with levels of at least 7% on four disparate types of humor.
The A1c of 6.99% or less group scored significantly higher for both affiliative humor and self-enhancing humor. This implies that better diabetes control is associated with positive humor. This was expected, as was the finding that negative humor was not associated with better control.
On the other hand, there was no significant difference between participants on either type of negative humor, whether aggressive or self-defeating.
Finally, my third study, published in 2023 [with coauthor Nancy D. King, PhD], found that offering humor training to people with type 1 diabetes can strengthen both their affiliative and self-enhancing sense of humor, while leaving their aggressive or self-defeating humor unaffected.
Q: What is ‘positive humor,’ and why do you think it is associated with diabetes control?
A: Both affiliative and self-enhancing humor enhance a person’s sense of self and their relationships with others.
Affiliative humor has been shown to be positively correlated with self-esteem, psychological well-being, social intimacy, and emotional stability. It is also negatively correlated with depression and anxiety.
Self-enhancing humor involves the ability to maintain a humorous outlook on life and to use humor to regulate emotions and as a coping strategy. Like affiliative humor, it is correlated with cheerfulness, self-esteem, optimism, psychological well-being, and life satisfaction. It is negatively related to depression and anxiety.
The preponderance of literature suggests positive humor specifically is associated with buffering many of the risk factors and complications associated with diabetes.
Q: What could underlie the associations between humor and diabetes control?
A: Unfortunately, none of my studies have been able to determine cause and effect, although the most recent one came the closest.
While not reaching statistical significance, the mean reduction in A1c levels from 7.12% at baseline to 6.75% at the post–humor training assessment may very well imply a practical and psychological significance to patients.
I believe, with a larger sample size, significance will be achieved, and that the relationship between positive humor and diabetes control will be shown to be bidirectional, with positive humor improving diabetes control, and improved control improving positive humor.
I hypothesize this will also bring psychological and physiological benefits. After all, humor has already been associated with reduced blood glucose levels, reduced microvascular complications, improved heart health, reduced blood pressure, decreased levels of depression and anxiety.
Humor also helps us deal with stress and trauma, so a cause-and-effect relationship makes sense.
Q: Can a positive sense of humor be taught?
A: Absolutely. There is evidence that humor can be developed and strengthened. Paul McGhee, PhD, developed a seven-step humor training program that has been effective in elevating measures of humor across a number of studies.
Others have successfully developed their own protocols, and of course my third study demonstrated a significant increase in both affiliative and self-enhancing humor with training.
Q: Do you think humor training could be incorporated into diabetes care?
A: Humor training programs are easily accessible, incur low to no cost, and are easy to implement. Furthermore, once a person is trained, access to ongoing humor is free, readily available, and fun.
Several diabetes educators have also reported that humor can promote connections, encourage and support diabetes management, galvanize effectiveness, and increase an audience’s attention during education programs.

Humor also helps us deal with stress and trauma, so a cause-and-effect relationship makes sense.
Q: Can a positive sense of humor be taught?
A: Absolutely. There is evidence that humor can be developed and strengthened. Paul McGhee, PhD, developed a seven-step humor training program that has been effective in elevating measures of humor across a number of studies.
Others have successfully developed their own protocols, and of course my third study demonstrated a significant increase in both affiliative and self-enhancing humor with training.
Q: Do you think humor training could be incorporated into diabetes care?
A: Humor training programs are easily accessible, incur low to no cost, and are easy to implement. Furthermore, once a person is trained, access to ongoing humor is free, readily available, and fun.
Several diabetes educators have also reported that humor can promote connections, encourage and support diabetes management, galvanize effectiveness, and increase an audience’s attention during education programs.

Low-salt diet cut BP by 6 mm Hg in 1 week: CARDIA-SSBP
The CARDIA-SSBP trial involved 213 individuals aged 50-75 years, including those with and those without hypertension, and showed that the decline in blood pressure brought about by a low-salt diet was independent of hypertension status and antihypertensive medication use. It was also generally consistent across subgroups and did not result in excess adverse events.
“The blood pressure reduction we see here is meaningful, and comparable to that produced by one antihypertensive medication,” lead investigator Deepak Gupta, MD, Vanderbilt University Medical Center, Nashville, Tenn., said in an interview.
Dr. Gupta presented the CARDIA-SSBP study on Nov. 11 at the American Heart Association scientific sessions, held in Philadelphia. The study was published online in JAMA. The exact menus used in the study are available in a supplement to the JAMA paper.
“In order to live a healthy lifestyle, understanding what we eat has important health effects. Raised blood pressure contributes to one out of every eight deaths worldwide,” Dr. Gupta noted. “If people want to lower their blood pressure, attention to dietary sodium is one part of that. If individuals can stick with a low sodium diet, they may be able to stop taking one of their antihypertensive medications, and those who are normotensive will be less likely to develop hypertension.”
Commentators said the study had significant implications for public health, but they pointed out that maintaining a low-sodium diet over the long term is challenging, given the high salt content of generally available foods.
Dr. Gupta noted that the study did use commercially available products in the low-sodium diets and the menus are available for people to follow, making it more accessible than some diets used in previous studies.
“What may also be attractive to people is that you don’t have to wait for months to see an effect. If you start to consume a low-sodium diet, you can see results on blood pressure rapidly, within a week,” he said.
The diet in this study brought about a large reduction in dietary sodium, but Dr. Gupta says any reduction in dietary sodium is likely to be beneficial.
“If you go to the level that we got to, you could expect to see a reduction of around 6 mm Hg. But it’s like walking – you don’t necessarily need to get to 10,000 steps every day. Any amount of walking or physical activity is of benefit. The same is probably true for salt: Any reduction that you can make is probably of benefit.”
For the study, participants had their blood pressure measured by 24-hour ambulatory monitoring while on their usual diets. They were then randomly assigned to either a high-sodium diet or a low-sodium diet for 1 week. Participants then crossed over to the opposite diet for 1 week, with blood pressure measured over a 24-hour period on the last day of each diet.
As assessed by 24-hour urine excretion, the usual diet of participants was found to already be high in sodium (median, 4.45 g/d). This increased to a median of 5.00 g/d when on the high-sodium diet in the study and decreased to 1.27 g/d while on the low-sodium diet.
Results found participants had a median systolic blood pressure of 125 mm Hg on their usual diets. This was raised to 126 mm Hg on the high-sodium diet and lowered to 119 mm Hg on the low-sodium diet.
The researchers also reported that 75% of individuals showed a blood pressure reduction on the low-sodium diet and are thus defined as “salt-sensitive.” This is a higher percentage than found in previous studies.
“Of those that didn’t show a blood pressure reduction with a low-sodium diet in this study, it appears that they may not have been so adherent to the diet as those who did show a blood pressure reduction,” Dr. Gupta said.
He noted that hypertension is the most common chronic disease condition worldwide, with about 1.3 billion people affected, and although it has been known for some time that dietary sodium affects blood pressure, there have been some gaps in previous studies.
For example, many studies have excluded individuals who were already taking antihypertensive medications and people with diabetes, and they have generally not included many older individuals. The current study found that all of these groups showed significant blood pressure reductions by reducing dietary sodium.
Large effect in people with diabetes
Subgroup analysis largely showed consistent results across the population, regardless of age, sex, race, and body mass index and whether participants were taking antihypertensive medication or not, but there were a couple of exceptions. Individuals with higher blood pressure at baseline seemed to have a greater effect of lowering dietary sodium, although those who were normotensive at baseline still showed significant blood pressure reduction, Dr. Gupta reported.
The researchers found a particularly large reduction in blood pressure from lowering sodium intake in people with diabetes, who made up about 21% of the overall cohort. Their average reduction in systolic blood pressure between the high and low sodium diet was close to 17 mm Hg rather than the 7-8 mm Hg in the whole cohort.
Dr. Gupta said that the results are applicable to most of the population.
“The people who will be most motivated to follow a low-sodium diet are those with hypertension. But even in normotensive individuals, there is likely to be benefit.”
To help people follow a low-sodium diet, Dr. Gupta says education campaigns are needed “to show people that they can do it and make it work.” But there are bigger structural issues that need to be addressed at policy and governmental levels.
“Most of our food available in grocery stores and restaurants is high in salt. We now have a preponderance of evidence showing us that we need to change what’s available in the food supply,” he said. “There is a push going on for this now, and the U.S. has introduced some guidelines for the food industry on sodium content of foods. These are voluntary at this point, but it’s a start.”
Difficult to maintain long term
Commenting on the study, Paul Whelton, MD, chair in global public health at Tulane University, New Orleans, noted that sodium reduction is known to reduce blood pressure, with greater sodium reductions giving greater blood pressure decreases, and that some people are more sensitive to the effects of sodium than others.
He described CARDIA-SSBP as a “well-done study.”
“They managed to get a very low sodium intake and a large difference between the two groups, which translated into a big reduction in systolic blood pressure,” Dr. Whelton said. “However, the problem with these sorts of trials where the diets are provided to the participants is that although they show proof of concept, it is difficult to generalize because we can’t normally provide patients with their meals. In this type of ‘feeding’ study, we find it difficult to maintain people on their behavioral intervention over the long term.”
Dr. Whelton said that he was more excited about this trial knowing that the food given was commercially available. “That makes it more practical, but you still have to be quite motivated to follow a diet like this. Buying low-sodium products in the supermarket does require quite a lot of work to read the labels, and sometimes the low-sodium foods are specialty products and are more expensive.”
He pointed out that older people in higher socioeconomic classes are more likely to attempt this and do better from behavioral interventions in general. “Unfortunately, people who don’t do well from behavioral interventions like this are those from lower socioeconomic groups, who are ones at most at risk for cardiovascular disease.”
Dr. Whelton noted that the food industry has been reluctant to lower sodium content because high-salt foods sell better. “Unfortunately, foods high in saturated fat and salt taste good to most people. We are generally attuned to a high salt intake. But when people have been following a low-salt diet for a while, they generally don’t like high-salt foods anymore. They become attuned to lower-sodium diet,” he added.
New U.S. sodium reduction guidelines
Discussant of the CARDIA-SSBP study at the AHA meeting, Cheryl Anderson, MD, University of California, San Diego, said that the findings were important and consistent with prior studies.
“These studies have global implications because salt is ubiquitous in the food supply in much of the world,” she noted, adding that, “Americans consume almost 50% more sodium than recommended, and there has been a persistent lack of adherence to healthy diet recommendations for reductions in salt, sugar, and fats.”
Dr. Anderson pointed out that in 2021, the Food and Drug Administration issued guidance for voluntary sodium reduction, which uses a gradual approach, with targets to reach a population goal of 3,000 mg/d of sodium by 2023 and 2,300 mg/d by 2031.
“These targets apply to 150 categories of food that are sales-weighted to focus on dominant sellers in each category. They apply to food manufacturers, restaurants and food service operations,” she concluded. “These targets serve as a basis for continued dialogue. The research community eagerly awaits the review of population-based data to help refine this approach and goals.”
This study was supported by grants from the National Heart, Lung, and Blood Institute, the National Institutes of Health, the American Heart Association, and the National Center for Advancing Translational Sciences. The authors report no disclosures.

FROM AHA 2023
Life in the woods
“I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach.” – Henry David Thoreau
I have many patients like Maxine. Tall, with a shock of white hair. Old, but still in charge. When you try to make eye contact, she looks right through you. First with her left eye. Then her right. Her face is inscrutable. What’s she thinking? Unlike many of my patients, however, this Maxine was a llama. Every morning my daughter and I tried to coax her into moving as we leaned on the cold steel gate that kept her in her pasture. We were visiting family in October and chose to stay on a working New England farm. The kids will love the animals, we thought, and we’ll appreciate the extra bedrooms.
Airbnb helped us find this charming fiber-farm in Rhode Island where they raise Leicester Longwool sheep, a historic breed that once roamed George Washington’s pastures, along with a few goats, ducks, chickens, and Maxine. It’s situated deep in the woods, which were yellow, orange, and red that week. As it happens, we were just a short drive due south of Walden Pond where Henry David Thoreau spent 2 years, 2 months and 2 days escaping “overcivilization” nearly 175 years ago. Hoisting our overweight bags over the uneven granite stone steps when we arrived, I realized this was going to be more like the Thoreau experiment than I intended. The farmhouse dated to the 1790s. There were wide, creaky floorboards, low ceilings, one staircase to the bedrooms (which could have aptly been called a ladder) and loads of book-laden shelves. Instructions posted in the kitchen warned that the heat is tricky to regulate – a redundant admonition as we watched our 3-year-old putting on her socks and shoes as she got into bed.
Now, if you’ve ever been on vacation with little kids, you know that it’s basically just childcare in a novel location. After barricading the staircase with luggage and unplugging lamps from their dicey outlets we set out to feed the chickens and try to pet a sheep. Walking the perimeter of the farm we saw stone walls that needed mending and stumbled across two ancient cemeteries, one had been for family, the other for slaves. I wondered how many farmers and weavers and menders had walked this trail with their kids over the generations.
The next morning, we learned that roosters do not in fact crow at dawn, they crow before dawn (which could also aptly be called nighttime). There were no commutes or late patients here. But there was work to be done. Chickens don’t care that it’s Sunday. It downpoured. Watching the sheep from the kitchen as I sipped my coffee, they didn’t seem to mind. Nor did our farmer hosts who trudged past them in tall boots, just as they had every other day of their farmer lives.
By the fifth day, we had fallen into the rhythms of the homestead. We cracked the blue, green, and brown eggs that our hosts placed outside our door in the early hours and made omelets that were as orange as the foliage. We finally learned to adjust the heat so we neither got chilblains nor had to open the windows and strip naked to cool down. The sky was a brilliant blue that last morning and Sloan ran around trying to catch leaves as they blew off the trees. She had no objective. No counting. No contest. Just chasing leaves as they fell. It was the ultimate atelic activity, done just for doing it. I joined her and found I was no better at this than a 3-year-old.
We might all benefit from a little time in the woods.

Nor did our farmer hosts who trudged past them in tall boots, just as they had every other day of their farmer lives.
By the fifth day, we had fallen into the rhythms of the homestead. We cracked the blue, green, and brown eggs that our hosts placed outside our door in the early hours and made omelets that were as orange as the foliage. We finally learned to adjust the heat so we neither got chilblains nor had to open the windows and strip naked to cool down. The sky was a brilliant blue that last morning and Sloan ran around trying to catch leaves as they blew off the trees. She had no objective. No counting. No contest. Just chasing leaves as they fell. It was the ultimate atelic activity, done just for doing it. I joined her and found I was no better at this than a 3-year-old.
We might all benefit from a little time in the woods.

“I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach.” – Henry David Thoreau
I have many patients like Maxine. Tall, with a shock of white hair. Old, but still in charge. When you try to make eye contact, she looks right through you. First with her left eye. Then her right. Her face is inscrutable. What’s she thinking? Unlike many of my patients, however, this Maxine was a llama. Every morning my daughter and I tried to coax her into moving as we leaned on the cold steel gate that kept her in her pasture. We were visiting family in October and chose to stay on a working New England farm. The kids will love the animals, we thought, and we’ll appreciate the extra bedrooms.
Airbnb helped us find this charming fiber-farm in Rhode Island where they raise Leicester Longwool sheep, a historic breed that once roamed George Washington’s pastures, along with a few goats, ducks, chickens, and Maxine. It’s situated deep in the woods, which were yellow, orange, and red that week. As it happens, we were just a short drive due south of Walden Pond where Henry David Thoreau spent 2 years, 2 months and 2 days escaping “overcivilization” nearly 175 years ago. Hoisting our overweight bags over the uneven granite stone steps when we arrived, I realized this was going to be more like the Thoreau experiment than I intended. The farmhouse dated to the 1790s. There were wide, creaky floorboards, low ceilings, one staircase to the bedrooms (which could have aptly been called a ladder) and loads of book-laden shelves. Instructions posted in the kitchen warned that the heat is tricky to regulate – a redundant admonition as we watched our 3-year-old putting on her socks and shoes as she got into bed.
Now, if you’ve ever been on vacation with little kids, you know that it’s basically just childcare in a novel location. After barricading the staircase with luggage and unplugging lamps from their dicey outlets we set out to feed the chickens and try to pet a sheep. Walking the perimeter of the farm we saw stone walls that needed mending and stumbled across two ancient cemeteries, one had been for family, the other for slaves. I wondered how many farmers and weavers and menders had walked this trail with their kids over the generations.
The next morning, we learned that roosters do not in fact crow at dawn, they crow before dawn (which could also aptly be called nighttime). There were no commutes or late patients here. But there was work to be done. Chickens don’t care that it’s Sunday. It downpoured. Watching the sheep from the kitchen as I sipped my coffee, they didn’t seem to mind. Nor did our farmer hosts who trudged past them in tall boots, just as they had every other day of their farmer lives.

False-positive mammography results and risk for cancer death
False-positive mammography results are common, but
Women with a false-positive mammography result had 61% greater risk of developing breast cancer and an 84% greater risk of dying of breast cancer, compared with those who did not have a false-positive result.
However, the investigators also found that the risk for breast cancer varied by individual characteristics such as age and breast density.
The analysis provides clues about which patients with false-positive mammography results will go on to develop breast cancer and “can be used to develop individualized risk-based breast cancer screening,” said the investigators, led by Xinhe Mao, MSc, of Karolinska Institute, Stockholm.
The findings were published online in JAMA Oncology.
About 11% of women in the United States and 2.5% in Europe will receive a false-positive result after a single mammography screening, and previous research shows that these women have a higher risk of developing breast cancer, compared with women without false-positive results. Still, whether this risk for breast cancer varies by individual characteristics and whether an association between a false-positive mammography result and mortality exists remain unclear.
To assess long-term outcomes after a false-positive result, the study investigators compared 45,213 women who had a false-positive mammography result between 1991 and 2017 with 452,130 controls matched for age, calendar year of mammography, and screening history. These data came from the Stockholm Mammography Screening program and Swedish nationwide registers. The analysis also included 1,113 women with a false-positive result and 11,130 matched controls with information on mammographic breast density from the Karolinska Mammography Project for Risk Prediction of Breast Cancer study.
Among women with a false-positive result, the 20-year cumulative breast cancer incidence was 11.3% compared with 7.3% among those without a false-positive (adjusted hazard ratio, 1.61).
Breast cancer risk was higher in older women – those aged 60-75 years (HR, 2.02) – vs younger women aged 40-49 years (HR, 1.38). Breast cancer risk was also higher among women with less dense breasts (HR, 4.65) vs more dense breasts (HR, 1.60) and those who underwent a biopsy during recall (HR, 1.77) vs those who did not (HR, 1.51).
After a false-positive result, cancers were more likely to occur on the ipsilateral side to the false-positive result (HR, 1.92) versus the contralateral (HR, 1.28) and were more common during the first 4 years of follow-up (HR, 2.57 in the first 2 years and 1.93 between 2 and 4 years). No statistical differences were observed based on tumor characteristics, aside from tumor size (HR, 1.78 for tumors ≥ 20 mm vs. 1.47 for smaller tumors).
The prognosis of patients with breast cancer did not differ on the basis of whether they had false-positive results before diagnosis (HR, 1.05 for a false-positive result versus no false-positive result; 95% CI, 0.89-1.25).
This study is the first to show that “women with a false-positive result are at increased risk of death from breast cancer,” Ms. Mao and colleagues concluded. This finding is “most probably associated with the increased breast cancer incidence,” given that the prognosis of patients with breast cancer was similar among those who had a false-positive result versus those who did not.
The authors noted that the increased risk for breast cancer after a false-positive result could suggest that false positives indicate the presence of small tumors that were missed or generally indicate a higher risk for breast cancer. Other factors, such as hormones or genetics, may be at play as well, but would need to be investigated in further studies, Ms. Mao and colleagues noted.
When individualizing surveillance after a false-positive result, age and breast density should be considered, the authors explained. Clinicians may also want to provide more intensive surveillance in the years after a false-positive result as well as education to patients about the risks associated with a false-positive result.
Overall, the findings indicate that clinicians “ should stress the importance of continued screening in women with false-positive results, given their higher risk of cancer, especially within the first 5 or so years after a false-positive result,” Diana L. Miglioretti, PhD, professor and division chief of biostatistics at the University of California, Davis, said in an interview.
Dr. Miglioretti, who has led research on false-positive mammography results and approaches to reduce false positives, noted that “this is a very important study confirming prior work by the Breast Cancer Surveillance Consortium showing individuals with false-positive screening mammography results are at increased risk of developing breast cancer in the future.”
The new evidence demonstrated an increased risk for death from breast cancer in patients who have a false-positive result is particularly worrisome because some studies suggest that women with false-positive results are less likely to return for screening, perhaps because of their negative experience, Dr. Miglioretti said.
However, her own research has shown that providing immediate screening mammography interpretation and same-day diagnostic workup to individuals who have not had a mammogram in the past 5 years and to younger women could prevent 40% of people from needing to return for diagnostic workup later and potentially reduce time to diagnosis for those with cancer.
It is “important that radiology facilities find ways to reduce false-positive results and the anxiety associated with these results,” Dr. Miglioretti said.
This study was supported by grants from the Swedish Research Council, the Swedish Cancer Society, the Stockholm County Council, and FORTE. Ms. Mao is supported by a grant from the China Scholarship Council. Dr. Miglioretti received funding from PCORI and NCI and royalties from Elsevier.

Study takes fine-grained look at MACE risk with glucocorticoids in RA
SAN DIEGO – Even when taken at low doses and over short periods, glucocorticoids (GCs) were linked to a higher risk of major adverse cardiovascular events (MACE) over the long term in a Veterans Affairs population of older, mostly male patients with rheumatoid arthritis, a new retrospective cohort study has found.
The analysis of nearly 19,000 patients, presented by rheumatologist Beth Wallace, MD, MSc, at the annual meeting of the American College of Rheumatology, showed that the level of risk for MACE rose with the dose, duration, and recency of GC use, in which risk increased significantly at prednisone-equivalent doses as low as 5 mg/day, durations as short as 30 days, and with last use as long as 1 year before MACE.
“Up to half of RA patients in the United States use long-term glucocorticoids despite previous work suggesting they increase MACE in a dose-dependent way,” said Dr. Wallace, assistant professor of medicine at the University of Michigan, Ann Arbor, and a rheumatologist at the VA Ann Arbor Healthcare Center. “Our group previously presented work suggesting that less than 14 days of glucocorticoid use in a 6-month period is associated with a two-thirds increase in odds of MACE over the following 6 months, with 90 days of use associated with more than twofold increase.”
In recent years, researchers such as Dr. Wallace have focused attention on the risks of GCs in RA. The American College of Rheumatology and the European Alliance of Associations for Rheumatology emphasize avoiding long-term use of GCs in RA and keeping doses as small and over the shortest amount of time as possible.
When Dr. Wallace and colleagues looked at the clinical pattern of GC use for patients with RA during the past 2 years, those who took 5 mg, 7.5 mg, and 10 mg daily doses for 30 days and had stopped at least a year before had risk for MACE that rose significantly by 3%, 5%, and 7%, respectively, compared with those who didn’t take GCs in the past 2 years.
While those increases were small, risk for MACE rose even more for those who took the same daily doses for 90 days, increasing 10%, 15%, and 21%, respectively. Researchers linked current ongoing use of GCs for the past 90 days to a 13%, 19%, and 27% higher risk for MACE at those respective doses.
The findings “add to the literature suggesting that there is some risk even with low-dose steroids,” said Michael George, MD, assistant professor of rheumatology and epidemiology at the University of Pennsylvania, Philadelphia, who did not take part in the research but is familiar with the findings.
“We can see that even glucocorticoids taken several years ago may affect cardiovascular risk but that recent use has a bigger effect on risk,” Dr. George said in an interview. “This study also suggests that very low-dose use affects risk.”
For the new study, Dr. Wallace and colleagues examined a Veterans Affairs database and identified 18,882 patients with RA (mean age, 62.5 years; 84% male; 66% GC users) who met the criteria of being > 40 and < 90 years old. The subjects had an initial VA rheumatology visit during 2010-2018 and were excluded if they had a non-RA rheumatologic disorder, prior MACE, or heart failure. MACE was defined as MI, stroke/TIA, cardiac arrest, coronary revascularization, or death from CV cause.
A total of 16% of the cohort had the largest exposure to GCs, defined as use for 90 days or more; 23% had exposure of 14-89 days, and 14% had exposure of 1-13 days.
The median 5-year MACE risk at baseline was 5.3%, and 3,754 patients (19.9%) had high baseline MACE risk. Incident MACE occurred in 4.1% of patients, and the median time to MACE was 2.67 years (interquartile ratio, 1.26-4.45 years).
Covariates included factors such as age, race, sex, body mass index, smoking status, adjusted Elixhauser index, VA risk score for cardiovascular disease, cancer, hospitalization for infection, number of rheumatology clinic visits, and use of lipid-lowering drugs, opioids, methotrexate, biologics, and hydroxychloroquine.
Dr. Wallace noted limitations including the possibility of residual confounding and the influence of background cardiovascular risk. The study didn’t examine the clinical value of taking GCs or compare that to the potential risk. Nor did it examine cost or the risks and benefits of alternative therapeutic options.
A study released earlier this year suggested that patients taking daily prednisolone doses under 5 mg do not have a higher risk of MACE. Previous studies had reached conflicting results.
“Glucocorticoids can provide major benefits to patients, but these benefits must be balanced with the potential risks,” Dr. George said. At low doses, these risks may be small, but they are present. In many cases, escalating DMARD [disease-modifying antirheumatic drug] therapy may be safer than continuing glucocorticoids.”
He added that the risks of GCs may be especially high in older patients and in those who have cardiovascular risk factors: “Often biologics are avoided in these higher-risk patients. But in fact, in many cases biologics may be the safer choice.”
No study funding was reported. Dr. Wallace reported no relevant financial relationships, and some of the other authors reported various ties with industry. Dr. George reported research funding from GlaxoSmithKline and Janssen and consulting fees from AbbVie.

“Up to half of RA patients in the United States use long-term glucocorticoids despite previous work suggesting they increase MACE in a dose-dependent way,” said Dr. Wallace, assistant professor of medicine at the University of Michigan, Ann Arbor, and a rheumatologist at the VA Ann Arbor Healthcare Center. “Our group previously presented work suggesting that less than 14 days of glucocorticoid use in a 6-month period is associated with a two-thirds increase in odds of MACE over the following 6 months, with 90 days of use associated with more than twofold increase.”
In recent years, researchers such as Dr. Wallace have focused attention on the risks of GCs in RA. The American College of Rheumatology and the European Alliance of Associations for Rheumatology emphasize avoiding long-term use of GCs in RA and keeping doses as small and over the shortest amount of time as possible.
When Dr. Wallace and colleagues looked at the clinical pattern of GC use for patients with RA during the past 2 years, those who took 5 mg, 7.5 mg, and 10 mg daily doses for 30 days and had stopped at least a year before had risk for MACE that rose significantly by 3%, 5%, and 7%, respectively, compared with those who didn’t take GCs in the past 2 years.
While those increases were small, risk for MACE rose even more for those who took the same daily doses for 90 days, increasing 10%, 15%, and 21%, respectively. Researchers linked current ongoing use of GCs for the past 90 days to a 13%, 19%, and 27% higher risk for MACE at those respective doses.
The findings “add to the literature suggesting that there is some risk even with low-dose steroids,” said Michael George, MD, assistant professor of rheumatology and epidemiology at the University of Pennsylvania, Philadelphia, who did not take part in the research but is familiar with the findings.
“We can see that even glucocorticoids taken several years ago may affect cardiovascular risk but that recent use has a bigger effect on risk,” Dr. George said in an interview. “This study also suggests that very low-dose use affects risk.”
For the new study, Dr. Wallace and colleagues examined a Veterans Affairs database and identified 18,882 patients with RA (mean age, 62.5 years; 84% male; 66% GC users) who met the criteria of being > 40 and < 90 years old. The subjects had an initial VA rheumatology visit during 2010-2018 and were excluded if they had a non-RA rheumatologic disorder, prior MACE, or heart failure. MACE was defined as MI, stroke/TIA, cardiac arrest, coronary revascularization, or death from CV cause.
A total of 16% of the cohort had the largest exposure to GCs, defined as use for 90 days or more; 23% had exposure of 14-89 days, and 14% had exposure of 1-13 days.
The median 5-year MACE risk at baseline was 5.3%, and 3,754 patients (19.9%) had high baseline MACE risk. Incident MACE occurred in 4.1% of patients, and the median time to MACE was 2.67 years (interquartile ratio, 1.26-4.45 years).
Covariates included factors such as age, race, sex, body mass index, smoking status, adjusted Elixhauser index, VA risk score for cardiovascular disease, cancer, hospitalization for infection, number of rheumatology clinic visits, and use of lipid-lowering drugs, opioids, methotrexate, biologics, and hydroxychloroquine.
Dr. Wallace noted limitations including the possibility of residual confounding and the influence of background cardiovascular risk. The study didn’t examine the clinical value of taking GCs or compare that to the potential risk. Nor did it examine cost or the risks and benefits of alternative therapeutic options.
A study released earlier this year suggested that patients taking daily prednisolone doses under 5 mg do not have a higher risk of MACE. Previous studies had reached conflicting results.
“Glucocorticoids can provide major benefits to patients, but these benefits must be balanced with the potential risks,” Dr. George said. At low doses, these risks may be small, but they are present. In many cases, escalating DMARD [disease-modifying antirheumatic drug] therapy may be safer than continuing glucocorticoids.”
He added that the risks of GCs may be especially high in older patients and in those who have cardiovascular risk factors: “Often biologics are avoided in these higher-risk patients. But in fact, in many cases biologics may be the safer choice.”
No study funding was reported. Dr. Wallace reported no relevant financial relationships, and some of the other authors reported various ties with industry. Dr. George reported research funding from GlaxoSmithKline and Janssen and consulting fees from AbbVie.

Impact of the COVID-19 Pandemic on Care for Patients With Atopic Dermatitis
To the Editor:
Atopic dermatitis (AD) is a widely prevalent dermatologic condition that can severely impact a patient’s quality of life.1 Individuals with AD have been substantially affected during the COVID-19 pandemic due to the increased use of irritants, decreased access to care, and rise in psychological stress.1,2 These factors have resulted in lower quality of life and worsening dermatologic symptoms for many AD patients over the last few years.1 One major potential contributory component of these findings is decreased accessibility to in-office care during the pandemic, with a shift to telemedicine instead. Accessibility to care during the COVID-19 pandemic for AD patients compared to those without AD remains unknown. Therefore, we explored the impact of the COVID-19 pandemic on care for patients with AD in a large US population.
Using anonymous survey data from the 2021 National Health Interview Survey,3 we conducted a population-based, cross-sectional study to evaluate access to care during the COVID-19 pandemic for patients with AD compared to those without AD. We assigned the following 3 survey questions as outcome variables to assess access to care: delayed medical care due to COVID-19 pandemic (yes/no), did not get care due to COVID-19 pandemic (yes/no), and virtual medical appointment in the last 12 months (yes/no). In Table 1, numerous categorical survey variables, including sex, health insurance status, race/ethnicity, education, US citizenship, birth in the United States, public assistance/welfare, and region, were analyzed using χ2 testing to evaluate for differences among individuals with and without AD. Multivariable logistic regression models evaluating the relationship between AD and access to care were constructed using Stata/MP 17 (StataCorp LLC). In our analysis we controlled for age, sex, health insurance status, race/ethnicity, education, US citizenship, birth in the United States, public assistance/welfare, and region.
There were 29,142 adult patients (aged ≥18 years) included in our analysis. Approximately 7.4% (weighted) of individuals had AD (Table 1). After adjusting for confounding variables, patients with AD had a higher odds of delaying medical care due to the COVID-19 pandemic (adjusted odds ratio [AOR], 1.91; 95% CI, 1.69-2.16; P<.001), not receiving care due to the COVID-19 pandemic (AOR, 1.94; 95% CI, 1.71-2.22; P<.001), and having a virtual medical visit in the last 12 months (AOR, 1.72; 95% CI, 1.54-1.93; P<.001)(Table 2) compared with patients without AD.
Our findings support the association between AD and decreased access to in-person care due to the COVID-19 pandemic. Moreover, telemedicine was utilized more among individuals with AD, possibly due to the accessibility of diagnostic tools for dermatologic diagnoses, such as high-quality photographs.4 According to Trinidad et al,4 telemedicine became an invaluable tool for dermatology hospitalists during the COVID-19 pandemic, as many physicians were able to comfortably diagnose patients with cutaneous diseases without an in-person visit. Utilizing telemedicine for patient care can help reduce the risk for COVID-19 transmission while also providing quality care for individuals living in rural areas.5 Chiricozzi et al6 discussed the importance of telemedicine in Italy during the pandemic, as many AD patients were able to maintain control of their disease while on systemic treatments.
Limitations of this study include self-reported measures; inability to compare patients with AD to individuals with other cutaneous diseases; and additional potential confounders, such as chronic comorbidities. Future studies should evaluate the use of telemedicine and access to care among individuals with other common skin diseases and help determine why such discrepancies exist. Understanding the difficulties in access to care and the viable alternatives in place may increase awareness and assist clinicians with adequate management of patients with AD.

Practice Points
- The landscape of dermatology has seen major changes due to the COVID-19 pandemic, as many patients now utilize telemedicine to receive care.
- Understanding accessibility to in-person care for patients with atopic dermatitis during the COVID-19 pandemic can assist with the development of methods to enhance management.
Aberrant Expression of CD56 in Metastatic Malignant Melanoma
To the Editor:
Many types of neoplasms can show aberrant immunoreactivity or unexpected expression of markers.1 Malignant melanoma is a tumor that can show not only aberrant immunohistochemical staining patterns but also notable histologic diversity,1,2 which often makes the diagnosis of melanoma challenging and ultimately can lead to diagnostic uncertainty.2
The incidence of malignant melanoma continues to grow.3 Maintaining a high degree of suspicion for this disease, recognizing its heterogeneity and divergent differentiation, and knowing potential aberrant immunohistochemical staining patterns are imperative for accurate diagnosis.
A 36-year-old man presented to a primary care physician with right-sided chest pain, upper and lower back aches, bilateral hip pain, neck pain, headache, night sweats, chills, and nausea. After infectious causes were ruled out, he was placed on a steroid taper without improvement. He presented to the emergency department a few days later with muscle spasms and was found to also have diffuse abdominal tenderness and guarding. The patient’s medical history was noncontributory; he was a lifelong nonsmoker. Laboratory studies revealed elevated levels of alanine aminotransferase and C-reactive protein. Computed tomography of the chest and abdomen revealed innumerable liver and lung lesions that were suspicious for metastatic malignancy. A liver biopsy revealed nests and sheets of metastatic tumor with pleomorphic nuclei, inconspicuous nucleoli, and areas of intranuclear clearing (Figures 1 and 2). Immunohistochemical staining was performed to further characterize the tumor. Neoplastic cells were positive for MART-1 (also known as Melan-A and melanoma-associated antigen recognized by T cells)(Figure 3), SOX10, S-100, HMB-45, and vimentin. Nonspecific staining with CD56 (Figure 4), a neuroendocrine marker, also was noted; however, the neoplasm was negative for synaptophysin, another neuroendocrine marker. Other markers for which staining was negative included pan-keratin, CD138 (syndecan-1), desmin, placental alkaline phosphatase (PLAP), inhibin, OCT-4, cytokeratin 7, and cytokeratin 20. This staining pattern was compatible with metastatic melanoma with aberrant CD56 expression.
BRAF V600E immunohistochemical staining also was performed and showed strong and diffuse positivity within neoplastic cells. A subsequent positron emission tomography scan revealed widespread metastatic disease involving the lungs, liver, spleen, and bones. The patient did not have a history of an excised skin lesion; no primary cutaneous or mucosal lesions were identified.
The patient was started on targeted therapy with trametinib, a mitogen-activated extracellular signal-related kinase kinase (MEK) inhibitor, and dabrafenib, a BRAF inhibitor. The disease continued to progress; he developed extensive leptomeningeal metastatic disease for which palliative radiation therapy was administered. The patient died 4 months after the initial diagnosis.
More than 90% of melanoma cases are of cutaneous origin; however, 4% to 8% of cases present as a metastatic lesion in the absence of an identified primary lesion,4 similar to our patient. The diagnosis of melanoma often is challenging; the tumor can show notable histologic diversity and has the potential to express aberrant immunophenotypes.1,2 The histologic diversity of melanoma includes a variety of architectural patterns (eg, nests, trabeculae, fascicular, pseudoglandular, pseudopapillary, or pseudorosette patterns), cytomorphologic features, and stromal changes. Cytomorphologic features of melanoma can be large pleomorphic cells; small cells; spindle cells; clear cells; signet-ring cells; and rhabdoid, plasmacytoid, and balloon cells.5
Melanoma can mimic carcinoma, sarcoma, lymphoma, benign stromal tumors, plasmacytoma, and germ-cell tumors.5 Nuclei can binucleated, multinucleated, or lobated and may contain inclusions or grooves. Stroma may become myxoid or desmoplastic in appearance or rarely show granulomatous inflammation or osteoclastic giant cells.5 These variations render the diagnosis of melanoma challenging and ultimately can lead to diagnostic uncertainty.
Melanomas typically express MART-1, HMB-45, S-100, tyrosinase, NK1C3, vimentin, and neuron-specific enolase. However, melanoma is among the many neoplasms that sometimes exhibit aberrant immunoreactivity and differentiation toward nonmelanocytic elements.6 The most commonly expressed immunophenotypic aberration is cytokeratin, especially the low-molecular-weight keratin marker CAM5.2.5 CAM5.2 positivity also is seen more often in metastatic melanoma. Melanomas rarely express other intermediate filaments, including desmin, neurofilament protein, and glial fibrillary acidic protein; expression of smooth-muscle actin is rare.5
Only a few cases of melanoma showing expression of neuroendocrine markers have been reported. However, one study reported synaptophysin positivity in 29% (10/34) of cases of primary and metastatic melanoma, making the stain a relatively common finding.1
In contrast, expression of CD56 (also known as neural-cell adhesion molecule 1) in melanoma has been reported only rarely. CD56 is a nonspecific neuroendocrine marker that normally is expressed on neurons, glial tissue, skeletal muscle, and natural killer cells. Riddle and Bui7 reported a case of metastatic malignant melanoma with focal CD56 positivity and no expression of other neuroendocrine markers, similar to our patient. Suzuki and colleagues4 also reported a case of melanoma metastatic to bone marrow that showed CD56 expression in true nonhematologic tumor cells and negative immunoreactivity with synaptophysin and chromogranin A.
It is important to document cases of melanoma that express neuroendocrine markers to prevent an incorrect diagnosis of a neuroendocrine tumor.1 In some cases, distinguishing amelanotic melanoma from poorly differentiated squamous cell carcinoma, neuroendocrine tumor, and lymphoma can be difficult.5
The term neuroendocrine differentiation is reserved for cases of melanoma that show areas of ultrastructural change consistent with a neuroendocrine tumor.2 Neuroendocrine differentiation in melanoma is not common; its prognostic significance is unknown.8 We do not consider our case to be true neuroendocrine differentiation, as the tumor lacked the morphologic changes of a neuroendocrine tumor. Furthermore, CD56 is a nonspecific neuroendocrine marker, and the tumor was negative for synaptophysin.
Melanoma has the potential to show notable histologic diversity as well as aberrant immunohistochemical staining patterns.1,2 Our patient had metastatic melanoma with aberrant neuroendocrine expression of CD56, which could have been a potential diagnostic pitfall. Because expression of CD56 in melanoma is rare, it is imperative to recognize this potential aberrant staining pattern to ensure the accurate diagnosis of melanoma and appropriate provision of care.

Other markers for which staining was negative included pan-keratin, CD138 (syndecan-1), desmin, placental alkaline phosphatase (PLAP), inhibin, OCT-4, cytokeratin 7, and cytokeratin 20. This staining pattern was compatible with metastatic melanoma with aberrant CD56 expression.
BRAF V600E immunohistochemical staining also was performed and showed strong and diffuse positivity within neoplastic cells. A subsequent positron emission tomography scan revealed widespread metastatic disease involving the lungs, liver, spleen, and bones. The patient did not have a history of an excised skin lesion; no primary cutaneous or mucosal lesions were identified.
The patient was started on targeted therapy with trametinib, a mitogen-activated extracellular signal-related kinase kinase (MEK) inhibitor, and dabrafenib, a BRAF inhibitor. The disease continued to progress; he developed extensive leptomeningeal metastatic disease for which palliative radiation therapy was administered. The patient died 4 months after the initial diagnosis.
More than 90% of melanoma cases are of cutaneous origin; however, 4% to 8% of cases present as a metastatic lesion in the absence of an identified primary lesion,4 similar to our patient. The diagnosis of melanoma often is challenging; the tumor can show notable histologic diversity and has the potential to express aberrant immunophenotypes.1,2 The histologic diversity of melanoma includes a variety of architectural patterns (eg, nests, trabeculae, fascicular, pseudoglandular, pseudopapillary, or pseudorosette patterns), cytomorphologic features, and stromal changes. Cytomorphologic features of melanoma can be large pleomorphic cells; small cells; spindle cells; clear cells; signet-ring cells; and rhabdoid, plasmacytoid, and balloon cells.5
Melanoma can mimic carcinoma, sarcoma, lymphoma, benign stromal tumors, plasmacytoma, and germ-cell tumors.5 Nuclei can binucleated, multinucleated, or lobated and may contain inclusions or grooves. Stroma may become myxoid or desmoplastic in appearance or rarely show granulomatous inflammation or osteoclastic giant cells.5 These variations render the diagnosis of melanoma challenging and ultimately can lead to diagnostic uncertainty.
Melanomas typically express MART-1, HMB-45, S-100, tyrosinase, NK1C3, vimentin, and neuron-specific enolase. However, melanoma is among the many neoplasms that sometimes exhibit aberrant immunoreactivity and differentiation toward nonmelanocytic elements.6 The most commonly expressed immunophenotypic aberration is cytokeratin, especially the low-molecular-weight keratin marker CAM5.2.5 CAM5.2 positivity also is seen more often in metastatic melanoma. Melanomas rarely express other intermediate filaments, including desmin, neurofilament protein, and glial fibrillary acidic protein; expression of smooth-muscle actin is rare.5
Only a few cases of melanoma showing expression of neuroendocrine markers have been reported. However, one study reported synaptophysin positivity in 29% (10/34) of cases of primary and metastatic melanoma, making the stain a relatively common finding.1
In contrast, expression of CD56 (also known as neural-cell adhesion molecule 1) in melanoma has been reported only rarely. CD56 is a nonspecific neuroendocrine marker that normally is expressed on neurons, glial tissue, skeletal muscle, and natural killer cells. Riddle and Bui7 reported a case of metastatic malignant melanoma with focal CD56 positivity and no expression of other neuroendocrine markers, similar to our patient. Suzuki and colleagues4 also reported a case of melanoma metastatic to bone marrow that showed CD56 expression in true nonhematologic tumor cells and negative immunoreactivity with synaptophysin and chromogranin A.
It is important to document cases of melanoma that express neuroendocrine markers to prevent an incorrect diagnosis of a neuroendocrine tumor.1 In some cases, distinguishing amelanotic melanoma from poorly differentiated squamous cell carcinoma, neuroendocrine tumor, and lymphoma can be difficult.5
The term neuroendocrine differentiation is reserved for cases of melanoma that show areas of ultrastructural change consistent with a neuroendocrine tumor.2 Neuroendocrine differentiation in melanoma is not common; its prognostic significance is unknown.8 We do not consider our case to be true neuroendocrine differentiation, as the tumor lacked the morphologic changes of a neuroendocrine tumor. Furthermore, CD56 is a nonspecific neuroendocrine marker, and the tumor was negative for synaptophysin.
Melanoma has the potential to show notable histologic diversity as well as aberrant immunohistochemical staining patterns.1,2 Our patient had metastatic melanoma with aberrant neuroendocrine expression of CD56, which could have been a potential diagnostic pitfall. Because expression of CD56 in melanoma is rare, it is imperative to recognize this potential aberrant staining pattern to ensure the accurate diagnosis of melanoma and appropriate provision of care.
To the Editor:
Many types of neoplasms can show aberrant immunoreactivity or unexpected expression of markers.1 Malignant melanoma is a tumor that can show not only aberrant immunohistochemical staining patterns but also notable histologic diversity,1,2 which often makes the diagnosis of melanoma challenging and ultimately can lead to diagnostic uncertainty.2
The incidence of malignant melanoma continues to grow.3 Maintaining a high degree of suspicion for this disease, recognizing its heterogeneity and divergent differentiation, and knowing potential aberrant immunohistochemical staining patterns are imperative for accurate diagnosis.
A 36-year-old man presented to a primary care physician with right-sided chest pain, upper and lower back aches, bilateral hip pain, neck pain, headache, night sweats, chills, and nausea. After infectious causes were ruled out, he was placed on a steroid taper without improvement. He presented to the emergency department a few days later with muscle spasms and was found to also have diffuse abdominal tenderness and guarding. The patient’s medical history was noncontributory; he was a lifelong nonsmoker. Laboratory studies revealed elevated levels of alanine aminotransferase and C-reactive protein. Computed tomography of the chest and abdomen revealed innumerable liver and lung lesions that were suspicious for metastatic malignancy. A liver biopsy revealed nests and sheets of metastatic tumor with pleomorphic nuclei, inconspicuous nucleoli, and areas of intranuclear clearing (Figures 1 and 2). Immunohistochemical staining was performed to further characterize the tumor. Neoplastic cells were positive for MART-1 (also known as Melan-A and melanoma-associated antigen recognized by T cells)(Figure 3), SOX10, S-100, HMB-45, and vimentin. Nonspecific staining with CD56 (Figure 4), a neuroendocrine marker, also was noted; however, the neoplasm was negative for synaptophysin, another neuroendocrine marker.

Practice Points
- The diagnosis of melanoma often is challenging as tumors can show notable histologic diversity and have the potential to express aberrant immunophenotypes including CD56 expression.
- Because expression of CD56 in melanoma is rare, it is important to be aware of this potential aberrant staining pattern.
- Recognizing this heterogeneity and divergent differentiation as well as knowing potential aberrant immunohistochemical staining patterns are imperative for accurate and timely diagnosis.
People with diabetes have a higher risk of colon cancer: Study
Getting a colonoscopy dramatically reduced the risk, the results showed.
The findings, published in JAMA Network Open, suggest that colonoscopies are particularly important for people with diabetes. People diagnosed with diabetes within the past 5 years have the greatest colorectal cancer risk, the study found, suggesting screening should be part of a person’s health care after they’re diagnosed with diabetes.
Researchers analyzed data for 54,597 people who contributed at least 2 years of health data as part of a study that recruited people from 12 Southeastern states between 2002 and 2009. The people self-reported their diabetes status, and although researchers tried to only include people with type 2 diabetes, it’s possible that some people in the study had type 1 diabetes. The average age of those in the study was 51 years old; 64% were women; more than half of them had an income of less than $15,000 per year; and 66% of them were African American.
Among the people in the study who had diabetes, the risk of having colorectal cancer was not strongly impacted by their race or ethnicity, gender, weight, or income level, the study showed.
While race didn’t predict whether people with diabetes would get colorectal cancer, the findings are particularly important because most of the people in the study were African American. Diabetes and colorectal cancer disproportionately affect African American people, the authors noted. Medical research studies often struggle to recruit people of color, resulting in a lack of data to help guide health care priorities and decision-making.
The study also provided important guidance for people newly diagnosed with diabetes. People who were diagnosed with diabetes within the past 5 years were at a particularly increased risk of getting colorectal cancer, compared to people who had been diagnosed for 5-10 years.
The authors concluded that increased referrals for colonoscopies among people with diabetes, particularly among those newly diagnosed, could greatly reduce the impact of colorectal cancer. Current guidelines suggest most people should begin colorectal cancer screenings at age 45, according to the Centers for Disease Control and Prevention.
The study was supported by the National Cancer Institute and the University of Wisconsin, Madison. The study authors reported no relevant conflicts of interest.

FTC considers proposals on mergers and noncompete clauses
Changes may be in store for how physicians do business based on pending proposals from the Federal Trade Commission to ban noncompete clauses and monitor potential merger monopolies.
In January 2023, the FTC announced a rule that would ban noncompete clauses, stating that such clauses reduce workers’ wages and stifle new businesses. Simply put, the rule would ban employers from entering into noncompete clauses with workers, including independent contractors.
Aspects of the rule include whether it should pertain to franchisees, whether senior executives should be exempted, and whether low-wage and high-wage workers should be treated differently.
According to the FTC, banning noncompete clauses would increase workers’ earnings by approximately $300 billion per year, save consumers as much as $148 billion in health care costs, and double the number of companies founded by former workers in the same field.
In June 2023, the FTC and the Department of Justice proposed changes to rules governing mergers, including changes to prenotification forms that would promote more efficient screening of potential mergers. According to a press release from the FTC, the proposed changes include provision of details about investments or corporate relationships, product and services, projected revenue streams, and previous acquisitions.
The proposal also includes a waiting period during which agencies would assess the risk that a merger would lessen competition or tend to create a monopoly.
What the FTC proposals mean for physicians
FTC Chair Lina M. Khan addressed attendees at the American College of Physicians at their annual meeting in October.
In March 2023, ACEP wrote to Ms. Khan in support of the banning of noncompete clauses. The ACEP also stated that the FTC should monitor the effect of a ban on the ability to recruit and maintain a stable physician workforce in rural and underserved areas “and should examine the potential impacts should nonprofit health systems be exempt from a ban.”
However, the American Medical Group Association, a nonprofit trade organization that supports multispecialty medical groups, opposes the ban. In a press release issued in March 2023, AMGA noted that, “As employers, AMGA members rely in part on noncompete agreements to build strong, sustainable care teams that work together to coordinate care for their patients. These care teams emphasize the importance of the doctor-patient relationship, which reasonable noncompete agreements help support.”
The American Medical Association supports the ban on noncompete clauses, detailed in an official AMA policy statement as, “support[ing] policies, regulations, and legislation that prohibits covenants not-to-compete for all physicians in clinical practice who hold employment contracts with for-profit or nonprofit hospital, hospital system, or staffing company employers.”
In regard to the merger guidelines, ACEP wrote a separate letter to Ms. Khan identifying some of the unique aspects of emergency medicine practice. The ACEP stressed the need for caution as the consolidation of medical practices continues, many under the umbrella of private equity investment companies.
“Unchecked mergers that substantially lessen competition in the labor market for emergency physicians, in which the employer is the buyer and the physician is the seller, can impact physicians directly by lowering wages or slowing wage growth, worsening benefits or working conditions, or contributing to other degradations in workplace quality,” according to ACEP.
The AMA also supports the FTC’s draft merger guidelines as protective of physicians and their working environments.
In September 2023, the AMA sent a letter to the FTC commending the agency on the proposed guidelines: “It is our strong contention that the agencies must have merger guidelines that protect physicians against health insurer mergers that may substantially lessen competition for the purchase of physician services and that degrade physician working conditions,” according to the AMA letter.
According the FTC, the proposed changes represent an expansion and reorganization of information along with the addition of new document requirements and represents the first comprehensive review of the Hart-Scott-Rodino Antitrust Improvements Act since 1978.
After soliciting public comments, the FTC is reviewing the proposals, and no specific date for a final vote has been announced.
More specifics on the potential changes to premerger notification, reporting, and waiting period requirements are available on the FTC website.

In September 2023, the AMA sent a letter to the FTC commending the agency on the proposed guidelines: “It is our strong contention that the agencies must have merger guidelines that protect physicians against health insurer mergers that may substantially lessen competition for the purchase of physician services and that degrade physician working conditions,” according to the AMA letter.
According the FTC, the proposed changes represent an expansion and reorganization of information along with the addition of new document requirements and represents the first comprehensive review of the Hart-Scott-Rodino Antitrust Improvements Act since 1978.
After soliciting public comments, the FTC is reviewing the proposals, and no specific date for a final vote has been announced.
More specifics on the potential changes to premerger notification, reporting, and waiting period requirements are available on the FTC website.
