TBD Meeting (3096-22)

INDIANAPOLIS – The way Maria C. Garzon, MD, sees it, capillary malformations are often misunderstood. She views them not as a single diagnosis but rather as a variety of conditions that fall under the term capillary malformation.

“The challenge is, we also use that term to describe a diagnosis,” Dr. Garzon, professor of dermatology and pediatrics at Columbia University, New York, said at the annual meeting of the Society for Pediatric Dermatology. “We have imperfect terminology. We use many different terms like capillary nevi and vascular stain. Instead of port wine stain, we now use the term port wine birthmark, and old terms like nevus flammeus are still used. This leads to diagnostic confusion, and it’s a barrier to developing care guidelines.”

Some capillary malformations, she noted, are benign and fade away while others can cause disfigurement or herald significant medical issues.

Histologically, she continued, not all capillary malformations are composed of capillaries. “Some are composed of postcapillary venules,” she said. “There are also mixed type capillary malformations that include lymphatic tissue, and the capillary malformation of capillary malformation-arteriovenous malformation (CM-AVM) syndrome shares histologic features of evolving AVMs as opposed to classic port wine birthmarks.”

The most recent International Society for the Study of Vascular Anomalies Classification of Vascular Anomalies was published in 2018 and is currently being updated. Other proposed clinical classifications have been published, including one that is diagnosis-specific and includes 20 different types of capillary malformations (J Eur Acad Dermatol Venereol. 2015 29[12]:2295-305, Pediatr Dermatol. 2016;33[6]:570-84).

“There are also syndromic classifications. Another question relates to the role of genomics: Are we ready for a classification that’s based purely on genetic variants, or do we need to incorporate it into existing classifications?” Dr. Garzon said. “Novel testing technologies using cell-free DNA and digital droplet PCR may be used in the future to establish diagnoses.” Genetic variants are found within capillary malformations, and they tend to be associated with three major pathways: the RAS-MAPK/ERK pathway, the PI3K/Akt/mTOR pathway, and the G protein pathway.

The type of capillary malformation that dermatologists and pediatricians most commonly see is nevus simplex, which occurs in 20%-82% of neonates. Other terms used include angel’s kiss, stork bite, salmon patch, nevus flammeus simplex, fading vascular stain, medial telangiectatic nevus, and butterfly mark. “It’s important to differentiate this from a port wine birthmark,” Dr. Garzon said. “This can be challenging when the birthmark is a darker red color. I have cared for patients who were initially thought to have nevus simplex and later found to have Sturge-Weber syndrome.”

Typical locations of nevus simplex include the central forehead/glabella, eyelids, the nape of the neck, scalp (parietal and occipital), nose, lip area (including philtrum), and the back (lumbosacral area and upper back). Most lesions fade/disappear without treatment (J Am Acad Dermatol. 2020;63[5]:805-14). Rare genetic syndromes associated with exaggerated nevus simplex complex include macrocephaly-capillary malformation syndrome and Beckwith-Wiedemann syndrome, “which tells us that this is a heterogeneous group of patients,” she said.

Dr. Garzon added that it’s “incredibly common” to see an eczema flare occurring within a nevus simplex on the nape of the neck. These patients will have a patch of atopic dermatitis that doesn’t get better. “Beneath it is their nevus simplex,” she said. “Remind parents that even after treating the eczema, the pink patch is not going to go away” (Pediatr Rep. 2021;13[1]:131-4).

Meanwhile, the classic port wine birthmark is usually congenital, uniform, and darker red in color. It darkens with maturity and the pattern will correlate with embryonic vasculature. “I am very wary of acquired port wine lesions,” she added. “It’s been described with trauma-related lesions, but early morphea can also mimic a port wine birthmark. You will see this if you’re practicing pediatric dermatology.”

Nearly a decade ago researchers established a link between port wine birthmarks and genetic variants in the GNAQ gene. “We see this in GNA11 as well,” Dr. Garzon said. “These changes are found in isolated port wine stains, and in Sturge-Weber syndrome. We now know that GNAQ drives the formation of large blood vessels through angiopoietin-2,” she noted (Arterioscler Throm Vasc Biol. 2022;42[1]:e27-43).

In general, studies that have examined genotype-phenotype correlations have demonstrated that the classic port wine birthmark is associated with GNAQ while GNA11 variants can be associated with a more reticulated pattern. “But this is not as clearcut as it seems,” she said. Investigators of a recent study showed an association between hypertension and renal anomalies in patients with skin capillary malformations and mosaic GNAQ or GNA11 variants. “This is a new finding,” she said. “Investigators are working to understand this association.”

Port wine birthmarks with the highest risk of Sturge-Weber syndrome include those that involve the forehead, upper eyelid, the midline frontonasal area, the hemifacial area, and median sites. “Patients who have this should be evaluated at birth,” Dr. Garzon said. “You should not delay for 2 months. They should be evaluated by ophthalmology and neurology early.”

The other morphologies commonly seen are “geographic” well-demarcated capillary malformations, which are dark in color. These lesions can be seen in conditions that are associated with genetic variants in PIK3CA (PROS) and include classic Klippel-Trenaunay syndrome, CLOVES (congenital lipomatous overgrowth, vascular malformations, epidermal nevi, scoliosis/skeletal and spinal) syndrome, and CLAPO (capillary malformation of the lower lip, lymphatic malformation of the face and neck, asymmetry of the face and limbs, and partial or generalized overgrowth) syndrome.

“Reticulated stains are much more heterogeneous,” Dr. Garzon said. “They can be localized or widespread. When you see a patient with a widespread reticulated capillary malformation, think about diffuse capillary malformation with overgrowth (DCMO). This condition is clinically and genetically heterogenous with the affected tissue of some patients showing variants in GNA11 while others have variants in PIK3CA. Therefore, a thorough examination at presentation and long-term follow-up is very important.”

Dr. Garzon disclosed that she is a member of the executive board for the International Society for the Study of Vascular Anomalies.

INDIANAPOLIS – Treating atopic dermatitis (AD) in children and adolescents with skin of color requires an acumen that extends well beyond the skin, said Candrice R. Heath, MD, at the annual meeting of the Society for Pediatric Dermatology.

This involves the practice of cultural humility, which Dr. Heath defined as a commitment to learn about all aspects of patients to truly understand them, including their race, access to health care, and socioeconomic status.

“We can continue to prioritize learning about all different types of skin tones and hair types, but we really have to commit to advocating for what our patients deserve in every way,” Dr. Heath, director of pediatric dermatology at Temple University, Philadelphia, said during her presentation at the meeting.

“That means advocating for kids to have access to better housing and for increasing health literacy programs in our hospitals, so that all our patients can understand what’s happening and how to navigate the health system,” she said. “It also means increasing diversity in our clinical trials by taking a few extra moments with the patient and family of color who might be eligible to participate in a clinical trial. We have work to do.”

To illustrate her points, she discussed the case of a 6-year-old Black patient, whose parents bring him into the clinic complaining about dark marks on the skin. The areas are itchy and the doctor figures, “this is a slam dunk; this is AD,” Dr. Heath said. “You talk about the diagnosis, and you give your treatment plan.

“But the issue is, in the parking lot when the patient’s family leaves, they feel like you didn’t help them at all,” she continued. “You didn’t understand what they came in for. They didn’t receive a treatment for what they came in for, because the initial complaint was dark marks on the skin, which is postinflammatory hyperpigmentation. We know that patients are distressed by this.”

As evidence, she cited a cross-sectional study that assessed the impact of hyperpigmentation and hyperchromia on quality of life in adults, published in the Journal of the American Academy of Dermatology. People who reported the highest levels of distress were women, those with postinflammatory hyperpigmentation, those with fewer formal years of education, and those who had higher out-of-pocket spending on skin-enhancing products.

“So, when you see hyperpigmentation in your AD patients of color, acknowledge it; say, ‘I see this pigmentation change,’ ” Dr. Heath advised. “Talk about how controlling the AD with a topical steroid or other treatment option can have a positive impact on that.”

However, she added that sometimes patients have steroid phobia, possibly because they believe the topical steroids are causing the pigmentation changes, “especially in cases of hypopigmentation, so I take the time to reassure patients so that they will not be fearful about using the medication.”

Parents of patients with skin of color who have AD may harbor other “invisible” concerns during office visits, she continued, including prior experiences with dermatologists that may not have been positive, difficulty accessing pediatric dermatologists, or a general mistrust of the health care system.

“All of that is going on in the room with your patients, particularly those with skin of color and those who feel marginalized,” said Dr. Heath, who is also a faculty scholar at Temple University medical school’s office of health equity, diversity and inclusion. “Of course, we can’t fix everything. But we can commit to approaching our visits with cultural humility.”

For patients with skin of color, she pointed out, other upstream effects impact AD care and outcomes, including well-documented socioeconomic factors.

“One of the equalizing factors is that we as pediatric dermatologists can think about increasing our education regarding skin of color,” Dr. Heath said.

For example, an analysis of data from the 2002 to 2012 National Inpatient Sample found that the main risk factors for inpatient hospitalization for AD were being non-White, having lowest-quartile household income, and having Medicaid or no insurance, researchers reported in 2018.

A separate multicenter study of 1,437 mother-child pairs with known AD found that non-Hispanic Black children and Hispanic children had greater odds of persistent AD than non-Hispanic White children, according to a 2019 study. Another large prospective cohort study published in 2019 found that AD prevalence and persistence is highest in U.S. urban children who are female or Black, and urban children with AD are more likely to have poor quality of life and asthma.

A few months after that study was published, researchers reported results from an analysis of data from the 2007-2008 National Survey of Children’s Health, which found that children who perceive the neighborhood they lived in as unsafe, unsupportive, or underdeveloped had a higher prevalence of AD and a higher severity of AD. The same year, a study of the social and economic risk factors for moderate to severe AD found that Black children were more likely to come from homes with a lower household income, lower parental education attainment, lack of home ownership, and live between two residences, and have exposure to smoke.

“Disease recognition is one thing, but we also want everyone to be aware of these other factors,” she said, “because some patients do need a little bit more care and help to be able to access the medications that they need and gain access to us.”

 

Follicular, nummular eczema

In her clinical experience, the most common clinical variants of AD in patients with skin of color is follicular eczema. “Examine the patient, apply your hand to the affected area, and you can feel the papules beneath your fingertips,” she advised.

“That’s what I teach my residents and medical students,” she said. “If you are looking for erythema to seal your diagnosis of AD, it may not happen. You may see more of a violaceous hue and sometimes you may not find it at all, depending on the patient’s skin tone. If I find an area of normal appearing skin and then look back at the area of active skin disease, I go back and forth until I’m able to train my eye to be able to see those violaceous and erythematous hues more easily.”

Nummular eczema can also be a challenge in AD patients with skin of color.

“I like to listen to buzz words,” Dr. Heath said. “If a parent says, ‘my child has been diagnosed with ringworm multiple times,’ I zoom in on that. We know that kids can get tinea corporis, but usually not multiple times. I ask about all the things that can be associated with AD, and often we do see these nummular plaques on the skin and do some education about that. I also talk to their pediatrician or send information to that person so that they can be aware that nummular eczema is a form of AD.”

She noted that AD of the scalp may be confused with tinea capitis, especially in young Black children with moderate to severe AD. In her experience, triamcinolone 0.1% ointment works well for AD of the scalp.

She concluded her presentation by noting that there is no easy solution to treating AD in young patients with skin of color. “It’s way more than just eczema. We can help people see AD in a different way. My goal is to see the value in challenging ourselves to understand the impact of what happens outside of the exam room on these patients.”

Dr. Heath disclosed that she has served as a consultant for several pharmaceutical companies, including Regeneron, Janssen, Arcutis, Johnson and Johnson, Cassiopea, and Lilly.

“That means advocating for kids to have access to better housing and for increasing health literacy programs in our hospitals, so that all our patients can understand what’s happening and how to navigate the health system,” she said. “It also means increasing diversity in our clinical trials by taking a few extra moments with the patient and family of color who might be eligible to participate in a clinical trial. We have work to do.”

To illustrate her points, she discussed the case of a 6-year-old Black patient, whose parents bring him into the clinic complaining about dark marks on the skin. The areas are itchy and the doctor figures, “this is a slam dunk; this is AD,” Dr. Heath said. “You talk about the diagnosis, and you give your treatment plan.

“But the issue is, in the parking lot when the patient’s family leaves, they feel like you didn’t help them at all,” she continued. “You didn’t understand what they came in for. They didn’t receive a treatment for what they came in for, because the initial complaint was dark marks on the skin, which is postinflammatory hyperpigmentation. We know that patients are distressed by this.”

As evidence, she cited a cross-sectional study that assessed the impact of hyperpigmentation and hyperchromia on quality of life in adults, published in the Journal of the American Academy of Dermatology. People who reported the highest levels of distress were women, those with postinflammatory hyperpigmentation, those with fewer formal years of education, and those who had higher out-of-pocket spending on skin-enhancing products.

“So, when you see hyperpigmentation in your AD patients of color, acknowledge it; say, ‘I see this pigmentation change,’ ” Dr. Heath advised. “Talk about how controlling the AD with a topical steroid or other treatment option can have a positive impact on that.”

However, she added that sometimes patients have steroid phobia, possibly because they believe the topical steroids are causing the pigmentation changes, “especially in cases of hypopigmentation, so I take the time to reassure patients so that they will not be fearful about using the medication.”

Parents of patients with skin of color who have AD may harbor other “invisible” concerns during office visits, she continued, including prior experiences with dermatologists that may not have been positive, difficulty accessing pediatric dermatologists, or a general mistrust of the health care system.

“All of that is going on in the room with your patients, particularly those with skin of color and those who feel marginalized,” said Dr. Heath, who is also a faculty scholar at Temple University medical school’s office of health equity, diversity and inclusion. “Of course, we can’t fix everything. But we can commit to approaching our visits with cultural humility.”

For patients with skin of color, she pointed out, other upstream effects impact AD care and outcomes, including well-documented socioeconomic factors.

“One of the equalizing factors is that we as pediatric dermatologists can think about increasing our education regarding skin of color,” Dr. Heath said.

For example, an analysis of data from the 2002 to 2012 National Inpatient Sample found that the main risk factors for inpatient hospitalization for AD were being non-White, having lowest-quartile household income, and having Medicaid or no insurance, researchers reported in 2018.

A separate multicenter study of 1,437 mother-child pairs with known AD found that non-Hispanic Black children and Hispanic children had greater odds of persistent AD than non-Hispanic White children, according to a 2019 study. Another large prospective cohort study published in 2019 found that AD prevalence and persistence is highest in U.S. urban children who are female or Black, and urban children with AD are more likely to have poor quality of life and asthma.

A few months after that study was published, researchers reported results from an analysis of data from the 2007-2008 National Survey of Children’s Health, which found that children who perceive the neighborhood they lived in as unsafe, unsupportive, or underdeveloped had a higher prevalence of AD and a higher severity of AD. The same year, a study of the social and economic risk factors for moderate to severe AD found that Black children were more likely to come from homes with a lower household income, lower parental education attainment, lack of home ownership, and live between two residences, and have exposure to smoke.

“Disease recognition is one thing, but we also want everyone to be aware of these other factors,” she said, “because some patients do need a little bit more care and help to be able to access the medications that they need and gain access to us.”

 

Follicular, nummular eczema

In her clinical experience, the most common clinical variants of AD in patients with skin of color is follicular eczema. “Examine the patient, apply your hand to the affected area, and you can feel the papules beneath your fingertips,” she advised.

“That’s what I teach my residents and medical students,” she said. “If you are looking for erythema to seal your diagnosis of AD, it may not happen. You may see more of a violaceous hue and sometimes you may not find it at all, depending on the patient’s skin tone. If I find an area of normal appearing skin and then look back at the area of active skin disease, I go back and forth until I’m able to train my eye to be able to see those violaceous and erythematous hues more easily.”

Nummular eczema can also be a challenge in AD patients with skin of color.

“I like to listen to buzz words,” Dr. Heath said. “If a parent says, ‘my child has been diagnosed with ringworm multiple times,’ I zoom in on that. We know that kids can get tinea corporis, but usually not multiple times. I ask about all the things that can be associated with AD, and often we do see these nummular plaques on the skin and do some education about that. I also talk to their pediatrician or send information to that person so that they can be aware that nummular eczema is a form of AD.”

She noted that AD of the scalp may be confused with tinea capitis, especially in young Black children with moderate to severe AD. In her experience, triamcinolone 0.1% ointment works well for AD of the scalp.

She concluded her presentation by noting that there is no easy solution to treating AD in young patients with skin of color. “It’s way more than just eczema. We can help people see AD in a different way. My goal is to see the value in challenging ourselves to understand the impact of what happens outside of the exam room on these patients.”

Dr. Heath disclosed that she has served as a consultant for several pharmaceutical companies, including Regeneron, Janssen, Arcutis, Johnson and Johnson, Cassiopea, and Lilly.

INDIANAPOLIS – Despite the common prevalence of skin-picking disorder and trichotillomania (hair pulling), no Food and Drug Administration–approved treatments exist for either condition.

And while both body-focused repetitive behavior disorders affect a greater proportion of females than males, “we have no current information that is useful about what hormonal influences may or may not play in terms of picking and pulling behaviors,” Jon E. Grant, MD, JD, MPH, professor of psychiatry and behavioral neuroscience at the University of Chicago, said at the annual meeting of the Society for Pediatric Dermatology. “On a cognitive level, affected children and adolescents often have impaired inhibitory control but they are often 1-2 standard deviations above average IQ. They have Type A personalities [and are] very driven young kids. They also do not tolerate any down time or boredom. They need to be doing something all the time.”

According to the DSM-5, the diagnostic criteria for skin picking includes recurrent skin picking that results in skin lesions and is not attributable to another medical condition or substance. It also involves repeated attempts to decrease or stop the behavior and causes clinically significant distress or impairment.

“The other medical condition that we are interested in is the misuse of or dependence upon amphetamines or other prescription-based or illicit stimulants,” Dr. Grant said. “I saw a young man who was using about 600 mg of Ritalin a day, and he was picking all over the place. He did not have a primary skin disorder.”

The lifetime prevalence of skin picking disorder ranges between 1.4% and 5.4% of the general population. However, about 63% of people in a community sample endorsed some form of skin picking, and in a study of 105 college students, almost 40% said they picked their skin and had noticeable tissue damage as a result.

“Skin picking is not the same as self-injury,” Dr. Grant said. “It is also not simply an anxiety disorder. Anxiety will make people who pick worse, so people will say that they pick when they’re under stress. I can give them benzodiazepines and they’re still going to pick.”

Animal and human studies demonstrate that skin picking and hair pulling primarily affect females. “You will encounter young boys that pick and pull, but it largely affects females, and it tends to start around puberty,” he said. “Picking can have an onset after the age of 30, which is quite uncommon.”

From a cognitive standpoint, pathological skin pickers demonstrate impaired inhibitory control, impaired stop signal reaction time, increased rates of negative urgency (a tendency to act impulsively in response to negative emotions), and increased rates of positive urgency (a tendency to act impulsively in response to exciting or pleasurable emotions).

Trichotillomania

The lifetime prevalence of trichotillomania ranges between 0.6% and 3.9%. The onset is typically from ages 10-13 years, and the mean duration of illness is 22 years.

The DSM-5 criteria for trichotillomania are similar to that of skin-picking disorder, “although we don’t really worry about the substance use issue with people who pull their hair,” Dr. Grant said. “It doesn’t seem to have a correlation.” In addition, sometimes, children “will worsen pulling or picking when they have co-occurring ADHD and they’ve been started on a stimulant, even at a typical dose. For kids who have those issues, we prefer to try nonstimulant options for their ADHD such as bupropion or atomoxetine.”

Individuals with trichotillomania also tend to have low self-esteem and increased social anxiety, he added, and about one-third report low or very low quality of life. “When you notice alopecia, particularly in young girls who often have longer hair, up to 20% will eat their hair,” Dr. Grant said. “We don’t know why. It’s not related to vitamin deficiencies; it’s not a pica type of iron deficiency. There seems to be a shame piece about eating one’s own hair, but it’s important to assess that. Ask about constipation or overflow incontinence because they can get a bezoar, which can rupture” and can be fatal.

Skin-picking disorder and trichotillomania co-occur in up to 20% of cases. “When they do it tends to be a more difficult problem,” he said. These patients often come for mental health care because of depression, and most, he added, say “I don’t think I would be depressed if I wasn’t covered with excoriations or missing most of my hair.”
 

Treatment for both conditions

According to Dr. Grant, the treatment of choice for skin-picking disorder and trichotillomania is a specific psychotherapy known as “habit reversal therapy,” which involves helping the patient gain better self-control. The drawback is that it’s difficult to find someone trained in habit reversal therapy, “who know anything about skin picking and hair pulling,” he said. “That has been a huge challenge in the field.”

In his experience, the medical treatment of choice for skin-picking disorder and trichotillomania is N-acetylcysteine, an over-the-counter amino acid and antioxidant, which has been shown to be helpful at a dose of 2,400 mg per day. “Patients report to me that some of the excoriations clear up a little quicker as they’re taking it,” Dr. Grant said.

There may also be a role for antipsychotic therapy, he said, “but because of the associated weight gain with most antipsychotics we prefer not to use them.”

The opioid antagonist naltrexone has been shown to be effective in the subset of patients with skin-picking or hair-pulling disorders whose parents have a substance use disorder, Dr. Grant said. “The thought is that there’s something addictive about this behavior in some kids. These kids will look forward to picking and find it rewarding and exciting.”

Dr. Grant reported having no relevant financial disclosures.

INDIANAPOLIS – If there’s one truth that David R. Stukus, MD, has come to realize from his 2 years as director of a food allergy treatment center, it’s that food allergies in children and adolescents are grossly overdiagnosed and misdiagnosed.

“When they’re given a diagnosis of food allergy, many families do not receive proper education to help them understand the risk as well as self-management and prognosis,” he said at the annual meeting of the Society for Pediatric Dermatology. “They are left to fend for themselves, which leads to increased anxiety. If they don’t understand what it means to manage their child’s food allergy, they’re going to think that they’re a ticking time bomb,” said Dr. Stukus, director of the Food Allergy Treatment Center and professor of pediatrics in the division of allergy and immunology at Nationwide Children’s Hospital in Columbus, Ohio.

During his presentation, he toured clinicians through best practices to diagnose and treat food allergies and shared cautionary tales of unsupported claims, unnecessary testing, and potential harm to misdiagnosed patients.

While food allergies can be serious and life-threatening, they are also manageable, he continued. It doesn’t mean that children with food allergies can’t go to school, attend baseball games, or participate in activities that any other child would. “Telling someone to adopt a restricted diet is not a benign recommendation,” he said. “That can cause real harm.”

Dr. Stukus defined food allergy as an immunologic response to an allergen that results in reproducible symptoms with every exposure. “Most commonly we’re going to see IgE-mediated food allergies, which often occur within minutes of eating certain foods,” he said.

Food intolerance, on the other hand, is a nonimmunologic response to a food that causes gastrointestinal symptoms with exposure. “This can come and go over time,” he said. “The most common example is lactose intolerance.”

Then there’s food sensitivity, which Dr. Stukus said is not a medical term but a marketing term often applied to a variety of symptoms without evidence to support its use.

“On the Internet you will find many companies marketing food sensitivity tests,” he said. “Gluten-free foods are now a billion-dollar industry. There are no validated tests to diagnose food sensitivity. All the blood tests measure IgG, which is memory antibody. If you eat a food, it is a normal response to produce IgG to it, but these companies will test all these things and when it comes back elevated, they say ‘Aha! This is your food sensitivity and this is why you’re not sleeping well at night.’ ” To illustrate the harm that can come from food allergy tests he discussed a 6-year-old girl who presented to his clinic several years ago with typical symptoms of allergic rhinitis. The parent reported a history of sneezing around dogs, itchy, watery eyes in the spring, recurrent cough, and frequent upper respiratory infections.

The referring physician had ordered an allergy panel, which flagged a long list of foods that the girl was supposedly allergic to, including banana, egg white, cod, and peanut. “This family was told to take all of these foods out of her diet,” Dr. Stukus said. “Interestingly, she had been seen by this physician for evaluation of environmental allergies, but the only ones included in the test were cat, cockroach, dog, and dust mite. They didn’t even include the spring pollen allergies. You want to avoid tests like this.”

Food sensitization is not the same as food allergy, he continued, noting that about 30% of all children will have detectable IgE toward peanuts, milk, egg, and shrimp, but that only about 5% are truly allergic to those foods.

“If we go by IgE testing alone, we’re going to overdiagnose the vast majority of people with food allergies that they don’t actually have,” he said. “Food allergy is diagnosed by the history and then confirmed by testing. With IgE-mediated food allergies we know that milk, egg, wheat, soy, finned fish, shellfish, and peanuts account for more than 90% of all food allergy reactions. Can any food potentially cause a food allergy? Yes, potentially, but we know that most fruits and vegetables and grains are very unlikely to cause an allergy.”

IgE-mediated food allergies are objective, immediate onset, and reproducible with every exposure to the offending food, no matter what form. Typical symptoms include hives, swelling, vomiting, runny nose/congestion, wheezing, hypotension, and anaphylaxis.

“We can also accurately identify infants that are more at risk to develop food allergies,” Dr. Stukus said. Infants with refractory atopic dermatitis often progress from eczema to food allergies to allergic rhinitis and asthma, the so-called “allergic march.” “Family history does have a role as well, but it’s not as significant,” he said. As for diagnostic tools, skin prick testing detects the presence of specific IgE bound to cutaneous mast cells and has a high negative predictive value and a low positive predictive value (around 50%).

With serum-specific IgE testing, levels of IgE for food and/or inhalant allergen can be obtained conveniently through routine venipuncture. Results are reported in ranges from 0.1 kU/L to 100 kU/L, and some are reported as arbitrary classes in levels of severity from 1 to 5.

“I highly discourage anybody from paying attention to arbitrary classes [on these reports],” Dr. Stukus said. “Those are meaningless. The absolute value is all that matters.”

He added that both skin and blood testing have high rates of false positive results. “We really need to use the history to help guide what tests we do; they were never designed to be used as screening tests, yet they’re used as screening tests on a regular basis,” he said. “There is also no indication to do shotgun testing. The reason why is because we see lots of cross reactivity on testing. If we have someone with peanut allergy and we start doing specific IgE testing for all legumes, more often than not we’re going to find detectable IgE, but it’s much less likely that they actually have clinical reactivity to foods like soy and beans.”

Dr. Stukus advises clinicians to consider certain questions before they order an allergen panel, the first being: Do I have the knowledge and experience to properly interpret the results?

“If you don’t know how to interpret the test, you probably shouldn’t order it in the first place,” he said. “If you do have the knowledge to interpret the results, will the results help to determine the diagnosis or change management? If not, why are you testing just to test? There is zero clinical indication to order a food allergy panel.” Dr. Stukus recommended a review of unproven tests for adverse reactions to foods published in 2018 in The Journal of Allergy and Clinical Immunology.

According to Dr. Stukus, potential harms from unproven food allergy tests include cost, unnecessary dietary avoidance, and a delay in diagnosis for the underlying condition. During the COVID-19 pandemic, he observed an increase in the number of patients with orthorexia, which he described as an eating disorder characterized by having an unsafe obsession with healthy food that becomes deeply rooted in the individual’s way of thinking to the point that it interferes with daily life.

“If you take someone who has anxiety at baseline, and then you give them a list of foods that they allegedly can’t eat, that’s going to cause worse anxiety,” he added. “We’re seeing that from the results of these tests.”

Dr. Stukus disclosed that he is a consultant for Before Brands, Kaleo, and Novartis. He is also associate editor of the Annals of Allergy, Asthma and Immunology.

IgE-mediated food allergies are objective, immediate onset, and reproducible with every exposure to the offending food, no matter what form. Typical symptoms include hives, swelling, vomiting, runny nose/congestion, wheezing, hypotension, and anaphylaxis.

“We can also accurately identify infants that are more at risk to develop food allergies,” Dr. Stukus said. Infants with refractory atopic dermatitis often progress from eczema to food allergies to allergic rhinitis and asthma, the so-called “allergic march.” “Family history does have a role as well, but it’s not as significant,” he said. As for diagnostic tools, skin prick testing detects the presence of specific IgE bound to cutaneous mast cells and has a high negative predictive value and a low positive predictive value (around 50%).

With serum-specific IgE testing, levels of IgE for food and/or inhalant allergen can be obtained conveniently through routine venipuncture. Results are reported in ranges from 0.1 kU/L to 100 kU/L, and some are reported as arbitrary classes in levels of severity from 1 to 5.

“I highly discourage anybody from paying attention to arbitrary classes [on these reports],” Dr. Stukus said. “Those are meaningless. The absolute value is all that matters.”

He added that both skin and blood testing have high rates of false positive results. “We really need to use the history to help guide what tests we do; they were never designed to be used as screening tests, yet they’re used as screening tests on a regular basis,” he said. “There is also no indication to do shotgun testing. The reason why is because we see lots of cross reactivity on testing. If we have someone with peanut allergy and we start doing specific IgE testing for all legumes, more often than not we’re going to find detectable IgE, but it’s much less likely that they actually have clinical reactivity to foods like soy and beans.”

Dr. Stukus advises clinicians to consider certain questions before they order an allergen panel, the first being: Do I have the knowledge and experience to properly interpret the results?

“If you don’t know how to interpret the test, you probably shouldn’t order it in the first place,” he said. “If you do have the knowledge to interpret the results, will the results help to determine the diagnosis or change management? If not, why are you testing just to test? There is zero clinical indication to order a food allergy panel.” Dr. Stukus recommended a review of unproven tests for adverse reactions to foods published in 2018 in The Journal of Allergy and Clinical Immunology.

According to Dr. Stukus, potential harms from unproven food allergy tests include cost, unnecessary dietary avoidance, and a delay in diagnosis for the underlying condition. During the COVID-19 pandemic, he observed an increase in the number of patients with orthorexia, which he described as an eating disorder characterized by having an unsafe obsession with healthy food that becomes deeply rooted in the individual’s way of thinking to the point that it interferes with daily life.

“If you take someone who has anxiety at baseline, and then you give them a list of foods that they allegedly can’t eat, that’s going to cause worse anxiety,” he added. “We’re seeing that from the results of these tests.”

Dr. Stukus disclosed that he is a consultant for Before Brands, Kaleo, and Novartis. He is also associate editor of the Annals of Allergy, Asthma and Immunology.

INDIANAPOLIS – If there’s one truth that David R. Stukus, MD, has come to realize from his 2 years as director of a food allergy treatment center, it’s that food allergies in children and adolescents are grossly overdiagnosed and misdiagnosed.

“When they’re given a diagnosis of food allergy, many families do not receive proper education to help them understand the risk as well as self-management and prognosis,” he said at the annual meeting of the Society for Pediatric Dermatology. “They are left to fend for themselves, which leads to increased anxiety. If they don’t understand what it means to manage their child’s food allergy, they’re going to think that they’re a ticking time bomb,” said Dr. Stukus, director of the Food Allergy Treatment Center and professor of pediatrics in the division of allergy and immunology at Nationwide Children’s Hospital in Columbus, Ohio.

During his presentation, he toured clinicians through best practices to diagnose and treat food allergies and shared cautionary tales of unsupported claims, unnecessary testing, and potential harm to misdiagnosed patients.

While food allergies can be serious and life-threatening, they are also manageable, he continued. It doesn’t mean that children with food allergies can’t go to school, attend baseball games, or participate in activities that any other child would. “Telling someone to adopt a restricted diet is not a benign recommendation,” he said. “That can cause real harm.”

Dr. Stukus defined food allergy as an immunologic response to an allergen that results in reproducible symptoms with every exposure. “Most commonly we’re going to see IgE-mediated food allergies, which often occur within minutes of eating certain foods,” he said.

Food intolerance, on the other hand, is a nonimmunologic response to a food that causes gastrointestinal symptoms with exposure. “This can come and go over time,” he said. “The most common example is lactose intolerance.”

Then there’s food sensitivity, which Dr. Stukus said is not a medical term but a marketing term often applied to a variety of symptoms without evidence to support its use.

“On the Internet you will find many companies marketing food sensitivity tests,” he said. “Gluten-free foods are now a billion-dollar industry. There are no validated tests to diagnose food sensitivity. All the blood tests measure IgG, which is memory antibody. If you eat a food, it is a normal response to produce IgG to it, but these companies will test all these things and when it comes back elevated, they say ‘Aha! This is your food sensitivity and this is why you’re not sleeping well at night.’ ” To illustrate the harm that can come from food allergy tests he discussed a 6-year-old girl who presented to his clinic several years ago with typical symptoms of allergic rhinitis. The parent reported a history of sneezing around dogs, itchy, watery eyes in the spring, recurrent cough, and frequent upper respiratory infections.

The referring physician had ordered an allergy panel, which flagged a long list of foods that the girl was supposedly allergic to, including banana, egg white, cod, and peanut. “This family was told to take all of these foods out of her diet,” Dr. Stukus said. “Interestingly, she had been seen by this physician for evaluation of environmental allergies, but the only ones included in the test were cat, cockroach, dog, and dust mite. They didn’t even include the spring pollen allergies. You want to avoid tests like this.”

Food sensitization is not the same as food allergy, he continued, noting that about 30% of all children will have detectable IgE toward peanuts, milk, egg, and shrimp, but that only about 5% are truly allergic to those foods.

“If we go by IgE testing alone, we’re going to overdiagnose the vast majority of people with food allergies that they don’t actually have,” he said. “Food allergy is diagnosed by the history and then confirmed by testing. With IgE-mediated food allergies we know that milk, egg, wheat, soy, finned fish, shellfish, and peanuts account for more than 90% of all food allergy reactions. Can any food potentially cause a food allergy? Yes, potentially, but we know that most fruits and vegetables and grains are very unlikely to cause an allergy.”

INDIANAPOLIS – When adolescents present with acne that is not responding to isotretinoin, make sure to ask if they’re taking the medication when eating fatty food – which is known to increase the drug’s bioavailability, advises James R. Treat, MD, a pediatric dermatologist at Children’s Hospital of Philadelphia.

“We see lots of teenagers who are on a restrictive diet,” which is “certainly one reason they could be failing isotretinoin,” Dr. Treat said at the annual meeting of the Society for Pediatric Dermatology.

Often, patients say that they have been referred to him because they had no response to 20 mg or 30 mg per day of isotretinoin. But after a dose escalation to 60 mg per day, their acne worsened.

If the patient’s acne is worsening with a cystic flare, “tripling the dose of isotretinoin is not something that you should do,” Dr. Treat said. “You should lower the dose and consider adding steroids.” For evidence-based recommendations on managing acne fulminans, he recommended an article published in the Journal of the American Academy of Dermatology in 2017.

Skin picking is another common reason for failure of isotretinoin, as well as with other acne therapies. These patients may have associated anxiety, which “might be a contraindication or at least something to consider before you put them on isotretinoin,” he noted.

In his experience, off-label use of N-acetylcysteine, an antioxidant and cysteine prodrug, has been “extremely effective” for patients with excoriation disorder. In a randomized trial of adults 18-60 years of age, 47% patients who took 1,200-3,000 mg per day doses of N-acetylcysteine for 12 weeks reported that their skin picking was much or very much improved, compared to 19% of those who took placebo (P = .03). The authors wrote that N-acetylcysteine “increases extracellular levels of glutamate in the nucleus accumbens,” and that these results support the hypothesis that “pharmacologic manipulation of the glutamate system may target core symptoms of compulsive behaviors.”

The tumor necrosis factor (TNF)-alpha blocker adalimumab is a reasonable option for patients with severe cystic inflammatory acne who fail isotretinoin, Dr. Treat said. In one published case, clinicians administered adalimumab 40 mg every other week for a 16-year-old male patient who received isotretinoin for moderate acne vulgaris, which caused sudden development of acne fulminans and incapacitating acute sacroiliitis with bilateral hip arthritis. Inflammatory lesions started to clear in 1 month and comedones improved by 3 months of treatment. Adalimumab was discontinued after 1 year and the patient remained clear.

“There are now multiple reports as well as some case series showing TNF-alpha agents causing clearance of acne,” said Dr. Treat, who directs the hospital’s pediatric dermatology fellowship program. A literature review of adalimumab, etanercept, and infliximab for treatment-resistant acne found that all agents had similar efficacy after 3-6 months of therapy. “We see this in our GI population, where TNF-alpha agents are helping their acne also,” he said. “We just have to augment it with some topical medications.”

Certain medications can drive the development of acne, including phenytoin, phenobarbital, lithium, MEK inhibitors, EGFR inhibitors, systemic steroids, and unopposed progesterone contraceptives. Some genetic conditions also predispose patients to acne, including mutations in the NCSTN gene and trisomy 13.

Dr. Treat discussed one of his patients with severe acne who had trisomy 13. The patient failed 12 months of doxycycline and amoxicillin in combination with a topical retinoid. He also failed low- and high-dose isotretinoin in combination with prednisone, as well as oral dapsone at a dose of 1 mg/kg per day for 3 months. He was started on adalimumab, but that was stopped after he flared. The patient is now maintained on ustekinumab monthly at a dose of 45 mg.

“I’ve only had a few patients where isotretinoin truly has failed,” Dr. Treat said. He described one patient with severe acne who had a hidradenitis-like appearance in his axilla and groin. “I treated with isotretinoin very gingerly in the beginning, [but] he flared significantly. I had given him concomitant steroids from the very beginning and transitioned to multiple different therapies – all of which failed.”

Next, Dr. Treat tried a course of systemic dapsone, and the patient responded nicely. “As an anti-inflammatory agent, dapsone is very reasonable” to consider, he said. “It’s something to add to your armamentarium.”

Dr. Treat disclosed that he is a consultant for Palvella and Regeneron. He has ownership interests in Matinas Biopharma Holdings, Axsome, Sorrento, and Amarin.

INDIANAPOLIS – An investigational topical treatment for dystrophic epidermolysis bullosa (DEB) known as beremagene geperpavec (B-VEC) showed durable and statistically significant improvement in complete wound healing at 3 and 6 months compared with placebo, according to results from a small phase 3 study.

DEB is a serious, ultra-rare genetic blistering disease caused by mutations in the COL7A1 gene, encoding for type VII collagen and leading to skin fragility and wounds. No approved therapies are currently available. In the study, treatment was generally well tolerated.

“B-VEC is the first treatment that has not only been shown to be effective, but the first to directly target the defect through topical application,” the study’s principal investigator, Shireen V. Guide, MD, said in an interview during a poster session at the annual meeting of the Society for Pediatric Dermatology. “It delivers type VII collagen gene therapy to these patients, which allows healing in areas that they may have had open since birth. It’s been life-changing for them.”

B-VEC is a herpes simplex virus (HSV-1)-based topical, redosable gene therapy being developed by Krystal Biotech that is designed to restore functional COL7 protein by delivering the COL7A1 gene. For the phase 3, multicenter, double-blind, placebo-controlled study known GEM-3, Dr. Guide, who practices dermatology in Rancho Santa Margarita, Calif., and her colleagues, including Peter Marinkovich, MD, from Stanford (Calif.) University, and Mercedes Gonzalez, MD, from the University of Miami, enrolled 31 patients aged 6 months and older with genetically confirmed DEB. Each patient had one wound treated randomized 1:1 to treatment with B-VEC once a week or placebo for 6 months. The mean age of the 31 study participants was 17 years, 65% were male, 65% were White, and 19% were Asian.

The primary endpoint was complete wound healing (defined as 100% wound closure from exact wound area at baseline, specified as skin re-epithelialization without drainage) at 6 months. Additional endpoints included complete wound healing at 3 months and change in pain associated with wound dressing changes.

At 3 months, 70% of wounds treated with B-VEC met the endpoint of complete wound healing, compared with 20% of wounds treated with placebo (P < .005). At 6 months, 67% of wounds treated with B-VEC met the endpoint of complete wound healing compared with 22% of those treated with placebo (P < .005).

Of the total wounds that closed at 3 months, 67% of wounds treated with B-VEC were also closed at 6 months, compared with 33% of those treated with placebo (P = .02). In other findings, a trend toward decreased pain was observed in wounds treated with B-VEC vs. those treated with placebo.

B-VEC was well tolerated with no treatment-related serious adverse events or discontinuations. Three patients experienced a total of five serious adverse events during the study: anemia (two events), and cellulitis, diarrhea, and positive blood culture (one event each). None were considered related to the study drug.

Dr. Guide, who is on staff at Children’s Health of Orange County, Orange, Calif., characterized B-VEC as “very novel because it’s very practical.”

To date, all treatments for DEB “have been extremely labor intensive, including skin grafting and hospitalizations. It’s a topical application that can be done in the office and potentially applied at home in the future. It’s also durable. Not only are the [treated] areas closing, but they are staying closed.”

Kalyani S. Marathe, MD, MPH, director of the dermatology division at Cincinnati Children’s Hospital, who was asked to comment on the study, said that topical application of B-VEC “allows the side effect profile to be very favorable. The results are remarkable in the amount of wound healing and reduction in pain.”

The tolerability of this medication “is crucial,” she added. “EB patients have a lot of pain from their wounds and so any treatment needs to be as painless as possible for it to be usable. I’m very excited about the next phase of studies for this medication and hopeful that it heralds new treatments for our EB patients.”

In June 2022, the manufacturer announced that it had submitted a biologics license application to the Food and Drug Administration for approval of B-VEC for the treatment of DEB, and that it anticipates submitting an application for marketing authorization with the European Medical Agency (EMA) in the second half of 2022.

Dr. Guide disclosed that she has served as an investigator for Krystal Biotech, Innovaderm Research, Arcutis, Premier Research, Paidion, and Castle Biosciences. Dr. Marathe disclosed that she has served as an adviser for Verrica, and that Cincinnati Children’s Hospital is a site for the next phase studies for B-VEC.

INDIANAPOLIS – An investigational topical treatment for dystrophic epidermolysis bullosa (DEB) known as beremagene geperpavec (B-VEC) showed durable and statistically significant improvement in complete wound healing at 3 and 6 months compared with placebo, according to results from a small phase 3 study.

DEB is a serious, ultra-rare genetic blistering disease caused by mutations in the COL7A1 gene, encoding for type VII collagen and leading to skin fragility and wounds. No approved therapies are currently available. In the study, treatment was generally well tolerated.

“B-VEC is the first treatment that has not only been shown to be effective, but the first to directly target the defect through topical application,” the study’s principal investigator, Shireen V. Guide, MD, said in an interview during a poster session at the annual meeting of the Society for Pediatric Dermatology. “It delivers type VII collagen gene therapy to these patients, which allows healing in areas that they may have had open since birth. It’s been life-changing for them.”

B-VEC is a herpes simplex virus (HSV-1)-based topical, redosable gene therapy being developed by Krystal Biotech that is designed to restore functional COL7 protein by delivering the COL7A1 gene. For the phase 3, multicenter, double-blind, placebo-controlled study known GEM-3, Dr. Guide, who practices dermatology in Rancho Santa Margarita, Calif., and her colleagues, including Peter Marinkovich, MD, from Stanford (Calif.) University, and Mercedes Gonzalez, MD, from the University of Miami, enrolled 31 patients aged 6 months and older with genetically confirmed DEB. Each patient had one wound treated randomized 1:1 to treatment with B-VEC once a week or placebo for 6 months. The mean age of the 31 study participants was 17 years, 65% were male, 65% were White, and 19% were Asian.

The primary endpoint was complete wound healing (defined as 100% wound closure from exact wound area at baseline, specified as skin re-epithelialization without drainage) at 6 months. Additional endpoints included complete wound healing at 3 months and change in pain associated with wound dressing changes.

At 3 months, 70% of wounds treated with B-VEC met the endpoint of complete wound healing, compared with 20% of wounds treated with placebo (P < .005). At 6 months, 67% of wounds treated with B-VEC met the endpoint of complete wound healing compared with 22% of those treated with placebo (P < .005).

Of the total wounds that closed at 3 months, 67% of wounds treated with B-VEC were also closed at 6 months, compared with 33% of those treated with placebo (P = .02). In other findings, a trend toward decreased pain was observed in wounds treated with B-VEC vs. those treated with placebo.

B-VEC was well tolerated with no treatment-related serious adverse events or discontinuations. Three patients experienced a total of five serious adverse events during the study: anemia (two events), and cellulitis, diarrhea, and positive blood culture (one event each). None were considered related to the study drug.

Dr. Guide, who is on staff at Children’s Health of Orange County, Orange, Calif., characterized B-VEC as “very novel because it’s very practical.”

To date, all treatments for DEB “have been extremely labor intensive, including skin grafting and hospitalizations. It’s a topical application that can be done in the office and potentially applied at home in the future. It’s also durable. Not only are the [treated] areas closing, but they are staying closed.”

Kalyani S. Marathe, MD, MPH, director of the dermatology division at Cincinnati Children’s Hospital, who was asked to comment on the study, said that topical application of B-VEC “allows the side effect profile to be very favorable. The results are remarkable in the amount of wound healing and reduction in pain.”

The tolerability of this medication “is crucial,” she added. “EB patients have a lot of pain from their wounds and so any treatment needs to be as painless as possible for it to be usable. I’m very excited about the next phase of studies for this medication and hopeful that it heralds new treatments for our EB patients.”

In June 2022, the manufacturer announced that it had submitted a biologics license application to the Food and Drug Administration for approval of B-VEC for the treatment of DEB, and that it anticipates submitting an application for marketing authorization with the European Medical Agency (EMA) in the second half of 2022.

Dr. Guide disclosed that she has served as an investigator for Krystal Biotech, Innovaderm Research, Arcutis, Premier Research, Paidion, and Castle Biosciences.

INDIANAPOLIS – Onset of recurrent reactive infectious mucocutaneous eruption (RIME) was most common among males between the ages of 11 and 12 years, which is younger than previously described, in a single-center retrospective study. In addition, 71% of patients with recurrent disease experienced 1-2 recurrences – episodes that were generally milder and occurred at variable intervals.

Those are among key findings from the study of 50 patients with RIME, presented by Catherina X. Pan at the annual meeting of the Society for Pediatric Dermatology.

Reactive infectious mucocutaneous eruption (RIME) is a novel term encompassing an array of rare, parainfectious mucositis diseases, noted Ms. Pan, a fourth-year medical student at Harvard Medical School, Boston. Previously known as Mycoplasma pneumoniae-induced rash and mucositis (MIRM), common clinical characteristics of RIME include less than 10% body surface area involvement of polymorphic skin lesions (vesiculobullous or targetoid macules/papules); erosive oral, genital, and/or ocular mucositis involving more than two sites, and evidence of prior infection including but not limited to upper respiratory infection, fever, and cough.

In addition to M. pneumoniae, other pathogens have been implicated, she said. “While the underlying etiology of the disease is not entirely clear, it’s become increasingly known that RIME tends to recur in a subset of patients.”

A cohort study of 13 patients with RIME found that Black race, male sex, and older age were predominant among the five patients who developed recurrent disease.

The estimated recurrence rate is between 8% and 38%, but the clinical characteristics of patients who develop recurrent RIME tend to be poorly understood, Ms. Pan said.

Along with her mentor, Sadaf Hussain, MD, of the department of dermatology at Boston Children’s Hospital, Ms. Pan conducted a retrospective chart review to characterize the clinical history and course of disease in patients diagnosed with recurrent RIME. They extracted data between January of 2000 and March of 2022 using ICD-10 codes used by board-certified dermatologists at Boston Children’s Hospital, as well as a text search for RIME or MIRM in the dermatology notes. Patients were included if they had a RIME/MIRM diagnosis by a board-certified dermatologist and/or infection on PCR/serology and mucositis involvement with limited skin involvement.

The study population included 50 patients: 24 with recurrent RIME and 26 with isolated RIME. The majority (66%) were male, and the mean age of RIME onset was between 11 and 12 years old, which is up to two years younger than previously reported in the case series of 13 patients. Most of the study participants (79%) were White, but there were no significant differences in patients who had recurrent RIME and those who had isolated RIME in terms of age, sex, or race.
 

Isolated vs. recurrent RIME

However, compared with patients who had isolated RIME, a greater proportion of those with recurrent RIME had a history of atopic disease (46% vs. 23%, respectively; P = .136), as well as a history of tonsillectomy and adenoidectomy (25% vs. 4%; P = .045). “This has not been previously observed, but it may generate a hypothesis that patients with a history of frequent infection as well as amplified immune responses may be associated with disease recurrence,” Ms. Pan said.

The average number of episodes among patients with recurrent RIME was 3.5 and the interval between episodes was variable, at a mean of 10.2 months. Ms. Pan reported that 71% of recurrent RIME patients experienced 1-2 episodes, although one patient experienced 9 episodes.

Clinically, episodes among all patients with RIME were characterized by infectious prodromal symptoms (69%), oral lesions (95%), ocular lesions (60%), genital lesions (41%) and cutaneous lesions (40%). However, RIME recurrences were less severe and more atypical, with 49% involving only one mucosal surface and 29% involving two mucosal surfaces. Also, except for oral lesions, rates of infectious prodromal symptoms and other lesions significantly decreased among recurrences compared with initial RIME.

“Notably, we found that M. pneumoniae was the most common known cause of RIME, particularly among the initial episodes,” Ms. Pan said. “However, 61% of recurrent RIME episodes did not have a known cause in terms of infectious etiology. And, concordant with prior studies, we also found decreased severity [of RIME recurrences] as indicated by decreased rates of emergency department presentation, hospitalization, and duration of hospitalization.”

In other findings, psychiatric complications such as anxiety and depression followed the onset of RIME in 33% of those with recurrent disease and 22% of those with isolated disease. In addition, the three most common treatments among all 50 patients were systemic steroids, topical steroids, and M. pneumoniae-specific antibiotics.

“While RIME is considered as typically milder than Stevens-Johnson syndrome and toxic epidermal necrolysis with low mortality rates, it can lead to severe complications including conjunctival shrinkage, corneal ulceration and scarring, blindness, and oral, ocular, urogenital synechiae,” Ms. Pan noted. “Increased use of corticosteroids and steroid-sparing agents such as IVIG have also been observed. Multidisciplinary care with ophthalmology, urology, and mental health services is critical.”

She acknowledged certain limitations of the study, including its retrospective, single-center design, and the possibility that milder cases may have been excluded due to a lack of accurate diagnosis or referral.

Carrie C. Coughlin, MD, who was asked to comment on the study results, pointed out that nearly half (24) of patients in the cohort experienced recurrent RIME. “This is a high proportion, suggesting counseling about the possibility of recurrence is more important than previously thought,” said Dr. Coughlin, director of the section of pediatric dermatology Washington University/St. Louis Children’s Hospital.

“Fortunately, recurrent cases tended to be less severe. However, many patients had more than one recurrence, making this challenging for affected patients.”

The researchers reported having no financial disclosures. Dr. Coughlin is on the board of the Pediatric Dermatology Research Alliance (PeDRA) and the International Immunosuppression and Transplant Skin Cancer Collaborative.

INDIANAPOLIS – In the opinion of Elena Pope, MD, MSc, it’s time to think of morphea in children as a systemic, chronic condition with associated extracutaneous manifestations and the potential for relapse.

“There is no correlation between the extent and activity of skin lesions and the presence, severity, and activity of extracutaneous manifestations,” Dr. Pope, professor of pediatrics at the University of Toronto and division head of pediatric dermatology at the Hospital for Sick Children in Toronto, said during the annual meeting of the Society for Pediatric Dermatology. “Treatment needs to be tailored to the extent of cutaneous manifestations, and I think we need to be aware of and address the impact on patients’ quality of life,” she added. There is also a need for more research “on targeted and better-tolerated therapies to put a stop to the progression of disease.”

Congenital morphea is a form of localized scleroderma that presents at birth but can be confused with port wine stain. Results from a multicenter retrospective review of 25 cases conducted by Dr. Pope and colleagues found that the median age at diagnosis was 2.9 years and 76% had linear-type lesions. In addition, 48% had extracutaneous involvement (all of these patients had linear morphea), most commonly of the central nervous system.

“It’s important to realize these lesions may become active over time,” Dr. Pope said. “In my experience, there are two different courses. Either you have innocuous lesions when the patients are born and they may become active around 3-4 years of age, or you have early intrauterine involvement, with lesions inactive at birth but with potential for significant damage in utero.”

She cautioned against treating a suspected port wine stain lesion with laser until congenital morphea is ruled out. “I’m aware of at least one lawsuit of a child where someone used a laser in a child who had progression with significant sclerosis,” she said. “The parents assumed it was the use of the laser that led to the progression, not the actual disease.”

Extracutaneous manifestations are common in morphea patients. A multicenter study of 750 patients with juvenile scleroderma found that 22% had extracutaneous manifestations. Almost half of patients (47%) had arthritis, but 17% had neurologic findings such as seizures and headaches, 9% had vascular manifestations, and 8% had uveitis. Subsequent studies found that neurological disease affects between 11% and 19% of cases, especially in those involving the head and neck.

“There is a wide range of manifestations from headache and neuropsychiatric changes to brain atrophy, seizures, and CNS cavernoma,” Dr. Pope said. “There also can be orthodental involvement such as malocclusion. It’s important to do a brain MRI, eye exam for uveitis, and don’t forget the orthodental assessment.”

She recalled a 10-year-old boy who presented to the Hospital for Sick Children with tissue loss on the forehead and eyebrow and eyelashes. He had no other congenital morphea symptoms and the MRI was normal, but the eye exam revealed uveitis. “It’s important to remember that uveitis is asymptomatic, so unless you look for it, you’re not going to find it,” she said.

According to unpublished data in 42 congenital morphea patients with lesions limited to the head and neck, who underwent MRI imaging at the Hospital for Sick Children, 57% had CNS changes that were ipsilateral in 68% of cases. “White matter changes were the most common, and to our surprise, there were patients who had progressive CNS disease, including CNS vasculitis, new lesions, and enhancement of prior stable lesions,” Dr. Pope said.

She recalled the case of an 8-year-old boy who presented to the hospital with intractable seizures. Upon completion of the MRI, one of the radiologists noted that the imaging showed subtle thinning of the forehead, and he was referred to Dr. Pope and colleagues for assessment. In the span of 4 years, despite aggressive treatment, the boy’s CNS disease progressed. “There was more enhancement, more tissue loss, his seizures are very hard to control, and he has many neurodevelopmental changes,” she recalled. “What I learned from this case is that skin activity does not correlate with imaging. Don’t assume that just because the skin is burnt out that the CNS will be the same. Also, the extent of skin disease does not predict involvement or progression of the CNS.”

Linear lesions on the lower extremities are a harbinger of orthopedic complications, which can occur in about half of patients. Joint contractures in this subset of patients are seen in about 81% of cases, while other sequelae can include arthritis, limb atrophy, leg-leg discrepancy, and angular deformity. “About 14% of patients require intervention,” Dr. Pope said. “In terms of working those patients up, you need to do an MRI and assess the extent of muscle and fascial involvement. Early physiotherapy and an orthopedic evaluation are also recommended.”

As for possible markers of morphea, antinuclear antibody is positive in 22%-68% of cases and correlates with disease severity, extracutaneous manifestations, and disease flare-up. Antihistone antibodies (AHA) are positive in about 47% of cases, “and that tends to correlate with the extent of skin and muscle involvement,” Dr. Pope said. “Anti–double-stranded DNA correlates with extent of disease, but the only known biomarker to date that correlates with disease activity is CXCL9/10. This has been documented in the skin as well as in the blood. So, this marker may help us determine if the patient needs to be treated or not.”



Treatments

For treatment of active localized disease, topical medications are helpful in some cases. Options include topical steroids, calcipotriol with or without betamethasone, imiquimod, and tacrolimus. “In my experience the combination of calcipotriol with betamethasone is best,” she said. “It really shuts down the activity fairly soon, and you can scale down to calcipotriol alone. I don’t find imiquimod very helpful for active lesions, although it has a role for inactive lesions.”

For patients with linear or generalized/mixed disease, “the combination of methotrexate and corticosteroids or methotrexate alone is probably the way to go,” Dr. Pope said. “The addition of steroids really depends on where the lesion is and how worried you are about other problems.”

According to the best available literature, 88% of patients should respond to treatment with methotrexate (MTX) and/or steroids within 3-6 months, and 74% within 3 months. “If they don’t, you have to wonder if the patient’s taking the medication, or you need to think about other alternative treatments,” she said. “Complete remission is possible in most of the patients, and the longer you treat the more you will see that. On average, most of us treat patients for about 3 years, but there are treatment failures as well. This can occur in up to 16% of patients.”

As for second-line treatment agents for congenital morphea, clinicians often turn to mycophenolate mofetil (MMF). Results from a retrospective longitudinal study of juvenile localized scleroderma patients found that after a mean of 9 years 91% of patients on MMF and 100% of patients on MTX had inactive disease. “There were no differences in relapse rates, although MMF seems to have a more sustained long-term effect and overall is better tolerated,” said Dr. Pope, who was not involved with the study. “However, it’s more immunosuppressive than MTX, which is important, especially in the era of COVID-19. You also need to think about the potential for more hematological suppression with MMF use.” If standard therapy fails, there is anecdotal data supporting the use of abatacept (which suppresses the T-cell activity in affected patients), tofacitinib (which inhibits transforming growth factor–beta), or dupilumab (which inhibits interleukin-4).

Dr. Pope emphasized the effect congenital morphea has on quality of life. Remarks from patients with facial morphea and their parents who participated in a focus group on the topic organized by the Hospital for Sick Children included, “You just want to stay inside because you are afraid of what people will say,” “They laugh at her. They make fun of her, and it’s terrible,” and “MTX makes me feel weird. I would throw up, feel dizzy.”

“You have to take that into consideration, because we cannot make the treatment worse than the disease,” Dr. Pope said. “There are many domains where patients could be affected, including skin symptoms, physical functioning, body image and social support, side effects of medication, and presence of extracutaneous manifestations. Predictors of poor quality of life include female sex and involvement of hands and feet.”

Dr. Pope disclosed that she has received grants/research support from AbbVie, Centocor, and Amgen. She has also received consulting fees from AbbVie, Sanofi, Novartis, Boehringer-Ingelheim, Phoenix, Amryt Pharma, and Timber Pharmaceuticals.

He had no other congenital morphea symptoms and the MRI was normal, but the eye exam revealed uveitis. “It’s important to remember that uveitis is asymptomatic, so unless you look for it, you’re not going to find it,” she said.

According to unpublished data in 42 congenital morphea patients with lesions limited to the head and neck, who underwent MRI imaging at the Hospital for Sick Children, 57% had CNS changes that were ipsilateral in 68% of cases. “White matter changes were the most common, and to our surprise, there were patients who had progressive CNS disease, including CNS vasculitis, new lesions, and enhancement of prior stable lesions,” Dr. Pope said.

She recalled the case of an 8-year-old boy who presented to the hospital with intractable seizures. Upon completion of the MRI, one of the radiologists noted that the imaging showed subtle thinning of the forehead, and he was referred to Dr. Pope and colleagues for assessment. In the span of 4 years, despite aggressive treatment, the boy’s CNS disease progressed. “There was more enhancement, more tissue loss, his seizures are very hard to control, and he has many neurodevelopmental changes,” she recalled. “What I learned from this case is that skin activity does not correlate with imaging. Don’t assume that just because the skin is burnt out that the CNS will be the same. Also, the extent of skin disease does not predict involvement or progression of the CNS.”

Linear lesions on the lower extremities are a harbinger of orthopedic complications, which can occur in about half of patients. Joint contractures in this subset of patients are seen in about 81% of cases, while other sequelae can include arthritis, limb atrophy, leg-leg discrepancy, and angular deformity. “About 14% of patients require intervention,” Dr. Pope said. “In terms of working those patients up, you need to do an MRI and assess the extent of muscle and fascial involvement. Early physiotherapy and an orthopedic evaluation are also recommended.”

As for possible markers of morphea, antinuclear antibody is positive in 22%-68% of cases and correlates with disease severity, extracutaneous manifestations, and disease flare-up. Antihistone antibodies (AHA) are positive in about 47% of cases, “and that tends to correlate with the extent of skin and muscle involvement,” Dr. Pope said. “Anti–double-stranded DNA correlates with extent of disease, but the only known biomarker to date that correlates with disease activity is CXCL9/10. This has been documented in the skin as well as in the blood. So, this marker may help us determine if the patient needs to be treated or not.”



Treatments

For treatment of active localized disease, topical medications are helpful in some cases. Options include topical steroids, calcipotriol with or without betamethasone, imiquimod, and tacrolimus. “In my experience the combination of calcipotriol with betamethasone is best,” she said. “It really shuts down the activity fairly soon, and you can scale down to calcipotriol alone. I don’t find imiquimod very helpful for active lesions, although it has a role for inactive lesions.”

For patients with linear or generalized/mixed disease, “the combination of methotrexate and corticosteroids or methotrexate alone is probably the way to go,” Dr. Pope said. “The addition of steroids really depends on where the lesion is and how worried you are about other problems.”

According to the best available literature, 88% of patients should respond to treatment with methotrexate (MTX) and/or steroids within 3-6 months, and 74% within 3 months. “If they don’t, you have to wonder if the patient’s taking the medication, or you need to think about other alternative treatments,” she said. “Complete remission is possible in most of the patients, and the longer you treat the more you will see that. On average, most of us treat patients for about 3 years, but there are treatment failures as well. This can occur in up to 16% of patients.”

As for second-line treatment agents for congenital morphea, clinicians often turn to mycophenolate mofetil (MMF). Results from a retrospective longitudinal study of juvenile localized scleroderma patients found that after a mean of 9 years 91% of patients on MMF and 100% of patients on MTX had inactive disease. “There were no differences in relapse rates, although MMF seems to have a more sustained long-term effect and overall is better tolerated,” said Dr. Pope, who was not involved with the study. “However, it’s more immunosuppressive than MTX, which is important, especially in the era of COVID-19. You also need to think about the potential for more hematological suppression with MMF use.” If standard therapy fails, there is anecdotal data supporting the use of abatacept (which suppresses the T-cell activity in affected patients), tofacitinib (which inhibits transforming growth factor–beta), or dupilumab (which inhibits interleukin-4).

Dr. Pope emphasized the effect congenital morphea has on quality of life. Remarks from patients with facial morphea and their parents who participated in a focus group on the topic organized by the Hospital for Sick Children included, “You just want to stay inside because you are afraid of what people will say,” “They laugh at her. They make fun of her, and it’s terrible,” and “MTX makes me feel weird. I would throw up, feel dizzy.”

“You have to take that into consideration, because we cannot make the treatment worse than the disease,” Dr. Pope said. “There are many domains where patients could be affected, including skin symptoms, physical functioning, body image and social support, side effects of medication, and presence of extracutaneous manifestations. Predictors of poor quality of life include female sex and involvement of hands and feet.”

Dr. Pope disclosed that she has received grants/research support from AbbVie, Centocor, and Amgen. She has also received consulting fees from AbbVie, Sanofi, Novartis, Boehringer-Ingelheim, Phoenix, Amryt Pharma, and Timber Pharmaceuticals.

INDIANAPOLIS – In the opinion of Elena Pope, MD, MSc, it’s time to think of morphea in children as a systemic, chronic condition with associated extracutaneous manifestations and the potential for relapse.

“There is no correlation between the extent and activity of skin lesions and the presence, severity, and activity of extracutaneous manifestations,” Dr. Pope, professor of pediatrics at the University of Toronto and division head of pediatric dermatology at the Hospital for Sick Children in Toronto, said during the annual meeting of the Society for Pediatric Dermatology. “Treatment needs to be tailored to the extent of cutaneous manifestations, and I think we need to be aware of and address the impact on patients’ quality of life,” she added. There is also a need for more research “on targeted and better-tolerated therapies to put a stop to the progression of disease.”

Congenital morphea is a form of localized scleroderma that presents at birth but can be confused with port wine stain. Results from a multicenter retrospective review of 25 cases conducted by Dr. Pope and colleagues found that the median age at diagnosis was 2.9 years and 76% had linear-type lesions. In addition, 48% had extracutaneous involvement (all of these patients had linear morphea), most commonly of the central nervous system.

“It’s important to realize these lesions may become active over time,” Dr. Pope said. “In my experience, there are two different courses. Either you have innocuous lesions when the patients are born and they may become active around 3-4 years of age, or you have early intrauterine involvement, with lesions inactive at birth but with potential for significant damage in utero.”

She cautioned against treating a suspected port wine stain lesion with laser until congenital morphea is ruled out. “I’m aware of at least one lawsuit of a child where someone used a laser in a child who had progression with significant sclerosis,” she said. “The parents assumed it was the use of the laser that led to the progression, not the actual disease.”

Extracutaneous manifestations are common in morphea patients. A multicenter study of 750 patients with juvenile scleroderma found that 22% had extracutaneous manifestations. Almost half of patients (47%) had arthritis, but 17% had neurologic findings such as seizures and headaches, 9% had vascular manifestations, and 8% had uveitis. Subsequent studies found that neurological disease affects between 11% and 19% of cases, especially in those involving the head and neck.

“There is a wide range of manifestations from headache and neuropsychiatric changes to brain atrophy, seizures, and CNS cavernoma,” Dr. Pope said. “There also can be orthodental involvement such as malocclusion. It’s important to do a brain MRI, eye exam for uveitis, and don’t forget the orthodental assessment.”

She recalled a 10-year-old boy who presented to the Hospital for Sick Children with tissue loss on the forehead and eyebrow and eyelashes. He had no other congenital morphea symptoms and the MRI was normal, but the eye exam revealed uveitis. “It’s important to remember that uveitis is asymptomatic, so unless you look for it, you’re not going to find it,” she said.

INDIANAPOLIS – Nearly two-thirds of pediatric patients with hidradenitis suppurativa (HS) met criteria for obesity at the time of their diagnosis, and 36% had acne, in a study presented at the annual meeting of the Society for Pediatric Dermatology.

In addition, 44% presented with scarring, which suggests that HS may be underdiagnosed in this patient population. Those are the key findings from the study, a single-center retrospective chart review presented by Stephanie Sanchez during a poster session at the meeting.

Doug Brunk/MDedge News

“There is limited research on HS within the pediatric population,” said Ms. Sanchez, a fourth-year medical student at Boston University. “It’s not very well defined or characterized.” The “unusually high number of pediatric patients with HS” at Boston Medical Center provided “a unique opportunity to study this topic.”

Working with her mentor, Lisa Shen, MD, associate medical director of pediatric dermatology at Boston University, Ms. Sanchez and colleagues retrospectively reviewed the medical records of 303 patients aged 4-18 years who were diagnosed with HS at Boston Medical Center from 2012 to 2021. Boston Medical Center is the largest safety net hospital in New England. All data points and outcome measures were collected within 6 months of the patient’s HS diagnosis date.

Of the 303 patients with HS, 84% were female and 16% were male. Complete information about race was available in 286 patients. Of these, 65% were Black/African American, 11% were White, and the rest were from other racial groups. The mean age at symptom onset was 13 years, while the mean age at diagnosis was 15 years, and the mean delay to diagnosis was 2 years. A family history of HS was reported in 36% of patients.

The most common clinical features in these HS patients were pain/tenderness (90%), pustules/papules (65%), discharge/drainage (62%), and deep-seated nodules (51%). Scarring was present in 44% of patients at the time of diagnosis. The three most common sites of involvement were the axillary area (79%), the pubic area (36%), and the inguinal folds/inner thighs (34%).

Obesity was the most common comorbidity at the time of diagnosis, with 64% of patients affected. The next most common comorbidities were acne vulgaris (36%), acanthosis nigricans (25%), depression (18%), being overweight (17%), polycystic ovary syndrome (16%) and anxiety (13%). None had type 1 diabetes or metabolic syndrome.

Referring to the large population of underserved minority patients at Boston Medical Center, Dr. Shen noted, “we have to make sure not to underestimate the prevalence of obesity in this population as they get older. We need to start from a younger age to incorporate multidisciplinary care such as weight management, nutrition, and working with our pediatric surgery colleagues in trying to tackle [HS] because there is data to suggest that the earlier we intervene, the better outcomes they have. That makes sense.”

Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, who was asked to comment on the findings, said that the study “highlights the impressive and concerning gap and delays in diagnosis, not too dissimilar to what the literature shows in adult HS patients, which unfortunately has tremendous ramifications, both physically and emotionally/psychosocially.”

While this single-center study identified potential risk factors, such as obesity and self-identifying as Black, he said, “it is important to note that this condition does not discriminate and therefore it is important not to miss the cases that don’t follow the textbook nor stigmatize this condition as one that only impacts certain demographics.”

The researchers reported having no financial disclosures. Dr. Friedman, who was not involved with the study, reported that he serves as a consultant and/or advisor to numerous pharmaceutical companies. He is a speaker for companies including, Regeneron, Sanofi, AbbVie, Janssen, Incyte, and Brickell Biotech, and has received grants from Pfizer, the Dermatology Foundation, Almirall, Incyte, Galderma, and Janssen.

INDIANAPOLIS – Three factors that may encourage trainees to pursue a career in pediatric dermatology include early exposure to the subspecialty during medical school, mentorship by a board-certified pediatric dermatologist at the trainee’s home institution, and increased salary benefits during and after fellowship.

Those are key findings from a survey of current and prior pediatric dermatology fellows, which sought to investigate what factors influence their career decisions.

According to the study’s principal investigator, Lucia Z. Diaz, MD, pediatric dermatology suffers from workforce shortages and geographic maldistribution as a subspecialty in the United States. She also noted that, from 2016 to 2021, 100% of pediatric dermatology applicants matched, yet about 15 of every 31 positions remained unfilled during each of those years. This suggests that there may be a lack of trainee mentorship secondary to a lack of available pediatric dermatologists.

“Somewhere along the way, we lose trainees to general dermatology, or they may go through a pediatric dermatology fellowship but not actually see children upon completion of their training,” Dr. Diaz, chief of pediatric dermatology at the University of Texas at Austin, said in an interview at the annual meeting of the Society for Pediatric Dermatology, where the study was presented during a poster session. “We wanted to find out factors influencing this.”

For the study, Dr. Diaz, Courtney N. Haller, MD, a first-year dermatology resident at the University of Texas at Austin, and their colleagues emailed a 37-item survey to 59 current and prior pediatric dermatology fellows who trained in the United States in the past 4 years (classes of 2019-2022). Current fellows were asked to share their future plans, and past fellows were asked to share details about their current practice situation including practice type (such as academics, private practice, and a mix of adult and pediatrics), and the researchers used descriptive statistics and chi-square analyses to evaluate qualitative data.

Doug Brunk/MDedge News

In all, 41 survey participants gave complete responses, and 3 gave partial responses. Of these, 8 were current fellows, 36 were past fellows, and 38 were female. The researchers found that 67% of survey respondents first became interested in pediatric dermatology in medical school, while the decision to pursue a fellowship occurred then (33%) or during their third year of dermatology residency (33%). Early exposure to pediatric dermatology, from medical school through dermatology PGY-2, was significantly associated with an early decision to pursue a pediatric dermatology career (P = .004).

In addition, respondents at institutions with two or more pediatric dermatology faculty were significantly more likely to cite home institution mentorship as an influencing factor in their career decision (P = .035).

“I thought that the interest in pediatric dermatology would peak early on during dermatology residency, but it primarily happens during medical school,” said Dr. Diaz, who is also associate director of the dermatology residency program at the medical school. “Mentorship and early exposure to pediatric dermatology during medical school are really important.”

The top three factors that discouraged respondents from pursuing a pediatric dermatology fellowship included a lack of salary benefit with additional training (83%), additional time required to complete training (73%), and geographic relocation (20%). After fellowship, 51% of respondents said they plan to or currently work in academic settings, while 88% said they plan to work full time or currently were working full time.

Interestingly, fellows with additional pediatric training such as an internship or residency were not more likely to see a greater percentage of pediatric patients in practice than those without this training (P = .14). The top 3 reasons for not seeing pediatric patients 100% of the clinical time were interest in seeing adult patients (67%), financial factors (56%), and interest in performing more procedures (56%).

In other findings, the top three factors in deciding practice location were proximity to extended family (63%), practice type (59%), and income (51%).

According to the study’s principal investigator, Lucia Z. Diaz, MD, pediatric dermatology suffers from workforce shortages and geographic maldistribution as a subspecialty in the United States. She also noted that, from 2016 to 2021, 100% of pediatric dermatology applicants matched, yet about 15 of every 31 positions remained unfilled during each of those years. This suggests that there may be a lack of trainee mentorship secondary to a lack of available pediatric dermatologists.

“Somewhere along the way, we lose trainees to general dermatology, or they may go through a pediatric dermatology fellowship but not actually see children upon completion of their training,” Dr. Diaz, chief of pediatric dermatology at the University of Texas at Austin, said in an interview at the annual meeting of the Society for Pediatric Dermatology, where the study was presented during a poster session. “We wanted to find out factors influencing this.”

For the study, Dr. Diaz, Courtney N. Haller, MD, a first-year dermatology resident at the University of Texas at Austin, and their colleagues emailed a 37-item survey to 59 current and prior pediatric dermatology fellows who trained in the United States in the past 4 years (classes of 2019-2022). Current fellows were asked to share their future plans, and past fellows were asked to share details about their current practice situation including practice type (such as academics, private practice, and a mix of adult and pediatrics), and the researchers used descriptive statistics and chi-square analyses to evaluate qualitative data.

In all, 41 survey participants gave complete responses, and 3 gave partial responses. Of these, 8 were current fellows, 36 were past fellows, and 38 were female. The researchers found that 67% of survey respondents first became interested in pediatric dermatology in medical school, while the decision to pursue a fellowship occurred then (33%) or during their third year of dermatology residency (33%). Early exposure to pediatric dermatology, from medical school through dermatology PGY-2, was significantly associated with an early decision to pursue a pediatric dermatology career (P = .004).

In addition, respondents at institutions with two or more pediatric dermatology faculty were significantly more likely to cite home institution mentorship as an influencing factor in their career decision (P = .035).

“I thought that the interest in pediatric dermatology would peak early on during dermatology residency, but it primarily happens during medical school,” said Dr. Diaz, who is also associate director of the dermatology residency program at the medical school. “Mentorship and early exposure to pediatric dermatology during medical school are really important.”

The top three factors that discouraged respondents from pursuing a pediatric dermatology fellowship included a lack of salary benefit with additional training (83%), additional time required to complete training (73%), and geographic relocation (20%). After fellowship, 51% of respondents said they plan to or currently work in academic settings, while 88% said they plan to work full time or currently were working full time.

Interestingly, fellows with additional pediatric training such as an internship or residency were not more likely to see a greater percentage of pediatric patients in practice than those without this training (P = .14). The top 3 reasons for not seeing pediatric patients 100% of the clinical time were interest in seeing adult patients (67%), financial factors (56%), and interest in performing more procedures (56%).

In other findings, the top three factors in deciding practice location were proximity to extended family (63%), practice type (59%), and income (51%).
