Dermatology

ASHEVILLE, N.C. – TikTok, typical of several forms of social media, has been intentionally repositioned to rival Google as a primary source of information, meaning that health care professionals, including those who provide dermatologic care to children, should be thinking about how to get on board to counter myths, erroneous facts, and fake news, warned an expert at the annual meeting of the Society for Pediatric Dermatology.

“If we don’t get involved, we are basically letting misinformation win. We need to be there,” said Angelo Landriscina, MD, director of dermatology at a Mount Sinai Doctors Clinic in New York.

Most of the content currently available on medical topics, including dermatology and pediatric dermatology, is not created by health care professionals, Dr. Landriscina noted. Not surprisingly, given that much of the content is based on personal opinion from individuals who have no expertise in medical care, he described the information as being of “low quality” when not fully erroneous.

Dr. Landriscina has been active on social media, including TikTok, for several years. Most of his posts involve responses to misinformation. When he sets the record straight on the basis of existing evidence, he often supports his counterargument with references.

He acknowledged that when he became involved in social media he faced criticism from colleagues about participating on an entertainment platform that many considered unworthy of providing objective information. If that was ever true, he argued, it is no longer the case.

“TikTok has adopted a new strategy. The goal is to unseat Google as a search tool, and it’s working,” he said. He explained that many people now use TikTok and other social media sites as their primary source of information on essentially every topic, from where to eat to whether to be screened for cancer.

The particular problem with TikTok – one of the most popular social media outlets – is that there is no mechanism for vetting the source of information. YouTube, by contrast, now requires some sort of validation for anyone who claims to have a medical degree or any other verifiable qualification, according to Dr. Landriscina. TikTok, like many other platforms, has no such requirement.

“Anyone can buy a pair of scrubs [implying expertise] and then post a video,” Dr. Landriscina said.

Even if information from one content provider is more valid than information from others, the TikTok algorithm is specifically designed to emphasize content that has the potential for going viral, which means it favors videos that are provocative over those that are not.

“The algorithm favors any content that is more controversial, more surprising, and keeps viewers engaged,” Dr. Landriscina pointed out.

This does not mean that objective and factual information is ignored, but the algorithm is indifferent to the validity of information, meaning that it allows videos to be posted without regard to whether the content is true, untrue, purposefully misleading, or utter nonsense. For that reason, it is often easier to attract attention by responding to a post that has already gone viral. Information that is clear and digestible can attract viewers and therefore is distributed more widely with the TikTok algorithm.
 

Parents are on Tiktok too

There is a misperception that the TikTok audience is younger, according to Dr. Landriscina. While peak use in the United States fell among people between the ages of 25 and 34 years in 2022, he said the number of users falls off relatively slowly with subsequent 10-year increments in age. In 2022, there were nearly 20 million users in the peak 10-year age range, but 7.5 million users were 55 years of age or older.

“Pediatric dermatologists should recognize that it is not just kids who are looking for information about their skin diseases, but also their parents,” Dr. Landriscina said.

The top three dermatology topics searched on TikTok in a recent period were acne, alopecia, and cysts. But top searches are very fluid and are extremely hard to quantify, because the basis of the algorithm, which is a proprietary secret, is not only unknown but produces different results for every user.

“The second you touch the app, it changes,” Dr. Landriscina said. He explained that an inquiry about any subject, including those that are medically related, yields content that is different, or at least ordered differently, “depending on how you behaved on the app in the past.”

The phenomenon that drives social media predates this technology. Dr. Landriscina cited a study in 1956 that described the “parasocial interaction theory.” The theory was based on the observation that those who consume media, such as television, which was relatively new in 1956, believed that they had a personal relationship with media figures.

“The users begin to trust influencers as a source, like a friend providing them advice,” Dr. Landriscina said. As an example, he suggested that a fan of the television show Friends who follows actor Jennifer Aniston on social media platforms may begin to think of her as a trusted source of information on any topic, including those for which she may not have expertise.

The reason that he urges medical professionals to become active on TikTok and other social media platforms is that they have a potentially critical role in responding to information that is not just wrong but harmful.

On TikTok and other social media platforms, “there is a lot of interest in content about dermatologic conditions in children. There is a real need for accurate information,” he said,

In the question-and-answer session following his presentation, Dr. Landriscina’s message was not uniformly embraced. One risk, according to an audience member, is that medical professionals will begin to express their own personal opinions rather than rely on evidence, with the result that they will “just add to the sea of misinformation.”

However, this opinion appeared to be the minority view. Most of those who commented took a “that-ship-has-sailed” stance, recognizing the irreversible ascendancy of social media.

“Whether you like it or not, social media is here to stay. We cannot fight it. Rather, we need to embrace it in a responsible way,” said Dakara R. Wright, MD, a dermatologist at the Mid-Atlantic Kaiser Permanente Group, Halethorpe, Md. She, like others, reported that she has come to recognize that social media is a major source of medical information for her patients.

“We need to be a presence on these platforms for the benefit of our patients and their parents,” she said. She acknowledged that she has not been active in posting on social media in the past but said that she has been speaking with administrators in her organization about how to become involved in a responsible way that can be useful to patients.

Candrice R. Heath, MD, assistant professor of dermatology at Temple University, Philadelphia, has been active on social media for several years, posting content on her own account, which is not related to her academic affiliation. She posts for many reasons, not least of which is drawing attention to her expertise.

Like Dr. Landriscina, she recognizes that users of these platforms are guided by the content to make decisions about health care. She also agreed that physicians should not ignore this phenomenon.

Tips on providing content

Given the fact that the algorithm is intended to produce posts that go viral, Dr. Landriscina urged clinicians to make their content easy to watch. He said it is not necessary to overthink content beyond providing accurate information, but he advised that videos be made with attention to adequate lighting and other simple factors to promote visual quality. He said that accurate information is not necessarily dull.

“Some facts can actually be surprising to patients,” he said. He noted that a calm, coherent video can be particularly effective in attracting an audience when it is in reaction to information that has gone viral but is misleading or patently incorrect.

Dr. Landriscina has been an influencer associated with multiple social media platforms, including TikTok. He has in the past been paid for consulting work for TikTok. Dr. Wright and Dr. Heath reported no potential conflicts of interest.

THE COMPARISON

A A 51-year-old Hispanic man with a squamous cell carcinoma (SCC) of the keratoacanthoma type on the arm.

B A 75-year-old Black man with an SCC of the keratoacanthoma type on the abdomen.

C An African woman with an SCC on the lower lip decades after a large facial burn, which is known as a Marjolin ulcer.

Cutaneous squamous cell carcinoma (SCC) develops from a malignant tumor of the keratinocytes, eccrine glands, or pilosebaceous units that invades the dermis. Risk factors include lighter skin tone, higher cumulative sun exposure, human papillomavirus (HPV) infection, hidradenitis suppurativa (HS), lichen sclerosus, family history of skin cancer,¹ and immunosuppression.² It typically affects sun-exposed areas of the body such as the face, scalp, neck, and extensor surfaces of the arms (FIGURE A).^3,4 However, in those with darker skin tones, the most common anatomic sites are those that are not exposed to the sun (FIGURE B). SCC is diagnosed via skin biopsy. Treatment options include surgical excision, destructive methods such as electrodesiccation and curettage, and Mohs micrographic surgery. Cutaneous SCC has a cure rate of more than 95% and a mortality rate of 1.5% to 2% in the United States.³

Epidemiology

SCC is the most common skin cancer occurring in Black individuals, manifesting primarily in the fifth decade of life.^5-7 It is the second most common skin cancer in White, Hispanic, and Asian individuals and is more common in males.⁸ In a study of organ transplant recipients (N = 413), Pritchett et al⁹ reported that HPV infection was a major risk factor in Hispanic patients because 66.7% of those with SCC had a history of HPV. However, HPV is a risk factor for SCC in all ethnic groups.¹⁰

Key clinical features in people with darker skin tones

Anatomic location

• The lower legs and anogenital areas are the most common sites for SCC in patients with skin of color.^4,11
• In Black women, SCC occurs more often on sun-exposed areas such as the arms and legs compared to Black men.^7,12-14
• The genitalia, perianal area, ocular mucosa, and oral mucosa are the least likely areas to be routinely examined, even in skin cancer clinics that see highrisk patients, despite the SCC risk in the anogenital area.^15,16
• Squamous cell carcinoma of the lips and scalp is more likely to occur in Black women vs Black men.^4,7,17

Clinical appearance

• In those with darker skin tones, SCCs may appear hyperpigmented4 or hyperkeratotic with a lack of erythema and an inconsistent appearance.^6,7,18
• A nonhealing ulceration of the skin should prompt a biopsy to rule out SCC.^3,19

Worth noting

In patients with darker skin tones, the risk for SCC increases in areas with chronic inflammation and scarring of the skin.^{4,6,7,11,18,20-22} In Black patients, 20% to 40% of cases of SCC occur in the setting of chronic inflammation and scarring.^6,7,18 Chronic inflammatory conditions include ulcers, lupus vulgaris, discoid lupus erythematosus, and HPV. In patients with discoid lupus erythematosus, there is an additive effect of sun exposure on the scars, which may play a role in the pathogenesis and metastasis risk for skin cancer in Black patients.⁴ Other scarring conditions include thermal or chemical burn scars, areas of physical trauma, and prior sites of radiation treatment.^14,23 SCC arising in a burn scar is called a Marjolin ulcer or malignant degeneration of a scar (FIGURE C). It is reported more often in lower-income, underresourced countries, which may suggest the need for early detection in populations with skin of color.²⁴

SCC is more aggressive in sites that are not exposed to sun compared to sun-exposed areas.^17,25

Continue to: The risk for SCC...

The risk for SCC is increased in immunocompromised patients,2 especially those with HPV.¹⁰

The prevalence of SCC in those with HS is approximately 4.6%. The chronic inflammation and irritation from HS in association with other risk factors such as tobacco use may contribute to the malignant transformation to SCC.²⁶

Health disparity highlight

• The risk for metastasis from SCC is 20% to 40% in Black patients vs 1% to 4% in White patients.^4,6,27
• Penile SCC was associated with a lower overall survival rate in patients of African descent.^20,21
• The increased morbidity and mortality from SCC in patients with skin of color may be attributed to delays in diagnosis and treatment as well as an incomplete understanding of tumor genetics.^4,6,18

• In those with darker skin tones, SCCs may appear hyperpigmented4 or hyperkeratotic with a lack of erythema and an inconsistent appearance.^6,7,18
• A nonhealing ulceration of the skin should prompt a biopsy to rule out SCC.^3,19

Worth noting

In patients with darker skin tones, the risk for SCC increases in areas with chronic inflammation and scarring of the skin.^{4,6,7,11,18,20-22} In Black patients, 20% to 40% of cases of SCC occur in the setting of chronic inflammation and scarring.^6,7,18 Chronic inflammatory conditions include ulcers, lupus vulgaris, discoid lupus erythematosus, and HPV. In patients with discoid lupus erythematosus, there is an additive effect of sun exposure on the scars, which may play a role in the pathogenesis and metastasis risk for skin cancer in Black patients.⁴ Other scarring conditions include thermal or chemical burn scars, areas of physical trauma, and prior sites of radiation treatment.^14,23 SCC arising in a burn scar is called a Marjolin ulcer or malignant degeneration of a scar (FIGURE C). It is reported more often in lower-income, underresourced countries, which may suggest the need for early detection in populations with skin of color.²⁴

SCC is more aggressive in sites that are not exposed to sun compared to sun-exposed areas.^17,25

Continue to: The risk for SCC...

The risk for SCC is increased in immunocompromised patients,2 especially those with HPV.¹⁰

The prevalence of SCC in those with HS is approximately 4.6%. The chronic inflammation and irritation from HS in association with other risk factors such as tobacco use may contribute to the malignant transformation to SCC.²⁶

Health disparity highlight

• The risk for metastasis from SCC is 20% to 40% in Black patients vs 1% to 4% in White patients.^4,6,27
• Penile SCC was associated with a lower overall survival rate in patients of African descent.^20,21
• The increased morbidity and mortality from SCC in patients with skin of color may be attributed to delays in diagnosis and treatment as well as an incomplete understanding of tumor genetics.^4,6,18

Asian American, Hispanic/Latino, and older individuals appear to have the greatest burden of vitiligo in the United States, according to the results of a cross sectional study.

To investigate the incidence and prevalence of diagnosed vitiligo in the United States, researchers used a 15% random sample of electronic medical records from the IBM Explorys database. Two cohorts were included: 2,980,778 patients diagnosed with vitiligo between Jan. 1, 2015, and Dec. 31, 2019 (incidence analysis), and 1,057,534 patients diagnosed with vitiligo between Jan. 1 and Dec. 31, 2019 (prevalence analysis).The main outcomes were incidence (per 100,000 person-years) and prevalence of diagnosed vitiligo overall and by age, race/ethnicity, and sex. Amit Garg, MD, a dermatologist with Northwell Health, New Hyde Park, N.Y., led the study, which was published in JAMA Dermatology.

The age- and sex-adjusted overall incidence rate of diagnosed vitiligo was 22.6 per 100,000 person-years, and the prevalence was 0.16%, the authors reported. The sex-adjusted IR was highest among patients aged 60-69 years (25.3 per 100,000 person-years); prevalence was highest among patients aged 70 years or older (0.21%).

The highest age-adjusted IR was among Asian American patients (41.2 per 100,000 person-years), followed by Hispanic/Latino patients (37.3 per 100,000 PY), those reporting other or multiple races (31.1 per 100,000), Black patients (29.6 per 100,000 person-years), and White patients (18.7 per 100,000 person-years). The highest age-adjusted prevalence was among Hispanic/Latino patients (0.29%), followed by Asian American patients (0.27%), those reporting other or multiple races (0.24%), Black patients (0.22%), and White patients (0.13%).

The burden of vitiligo in the United States is poorly understood, and the findings “may support improving awareness of vitiligo disease burden in medical and public sectors, informing research agendas, improving enrollment of racial and ethnic minority populations in trials, and developing health policies,” the authors wrote.

Limitations of the study included that the analysis only captured patients who sought care in health systems included in the database, and there was the potential for underreporting, “since not all patients with vitiligo seek care,” the authors noted.

Dr. Garg reported being an adviser for and receiving honoraria from many pharmaceutical companies. He has also received research grants from AbbVie, UCB, the National Psoriasis Foundation, and the CHORD COUSIN Collaboration. No other disclosures were reported.

On July 21, 2023, topical cantharidin became the first Food and Drug Administration–approved treatment of molluscum contagiosum (molluscum), for adults and pediatric patients 2 years of age and older.

The product is a drug-device combination that contains a formulation of cantharidin solution (0.7%), delivered topically via a single-use applicator, which allows for precise dosing and targeted administration. According to a press release from Verrica Pharmaceuticals, cantharidin is expected to be available by September 2023 and should be administered only by a trained health care professional; it is not for use in the home.

The approval of the product, also known as VP-102, is based on results from two identical multicenter phase 3 randomized, double-blind, placebo-controlled trials that evaluated the drug’s safety and efficacy in patients 2 years of age and older diagnosed with molluscum: Cantharidin Application in Molluscum Patients-1 (CAMP-1) and CAMP-2. Patients in both trials met the primary endpoint of complete clearance of all treatable molluscum lesions. Specifically, 46% of CAMP-1 participants treated with VP-102 achieved complete clearance of molluscum lesions compared with 18% of participants in the vehicle group (P < .0001), while 54% of CAMP-2 participants treated with VP-102 achieved complete clearance of molluscum lesions compared with 13% of participants in the vehicle group (P < .0001).

A post hoc analysis of both trials found that complete clearance of all lesions was significantly higher in the VP-102 group than vehicle across all body regions. It also found that there were no serious adverse reactions reported in the trials. Adverse reactions were mostly mild to moderate and included application site vesicles, erythema, pain, dryness, scab, discoloration, pruritus, and edema.

The product will be marketed as Ycanth.

In March of 2023, the FDA accepted a new drug application for another treatment for molluscum contagiosum, berdazimer gel 10.3%. That product is being developed by Novan.

Among more than 1,000 skin biopsies performed over the last 6 years by pediatric dermatologists at the University of California, San Francisco (UCSF), the three most common biopsy results were compound nevus, pyogenic granuloma, and spongiotic dermatitis.

In addition, fewer biopsies were performed in the first 3 years of the global COVID-19 pandemic than in the previous 3 years.

These findings from a retrospective analysis were presented during a poster session at the annual meeting of the Society for Pediatric Dermatology. The analysis set out to evaluate which patients required biopsy, which skin conditions were sampled, and if practice patterns changed following the start of the COVID-19 pandemic.

“The work is important because very few pediatric patients, relative to adult patients seen in dermatology clinics, have a biopsy done,” Kelly M. Cordoro, MD, one of the study authors, told this news organization.

“Approximately 1%-4% of pediatric patients visiting a dermatology clinic will have a biopsy done as compared to 30%-50% of adult patients. Understanding what is being biopsied in children sheds light on the medical decision-making required to decide when a biopsy is necessary,” said Dr. Cordoro, chief of pediatric dermatology at UCSF.

For the study, the researchers retrospectively reviewed 1,196 biopsy specimens from 1,080 unique patients that were performed by pediatric dermatologists at UCSF from 2017 to 2022. Half of the patients were female, their mean age was 11.5 years, and they ranged in age from 1 day to 61 years. Nearly half of biopsies (47%) were performed in patients aged 12-18 years and one-quarter (25.6%) were performed in those aged 6-11 years. In the remaining biopsies, 6.6% came from patients younger than 1 year, 5.8% of those aged 1-2 years, 7.3% from those aged 3-5 years, and 3.9% each in those aged 19-21 years and in those older than 21 years.

The five most common biopsy results were compound nevus (99 biopsies), pyogenic granuloma (96), spongiotic dermatitis (57), intradermal nevus (53), and pilomatricoma (40).

The researchers identified 30 malignant diagnoses in 28 unique patients, most commonly mycosis fungoides (in 16 patients with a median age of 12.5 years), basal cell carcinoma (in 5 patients with a median age of 9 years), and dermatofibrosarcoma protuberans (in 4 patients with a median age of 2 years).

There was no significant sex-based difference in the number of biopsies performed at a given age (P = .47), but Dr. Cordoro and colleagues noted a statistically significant decrease in the number of biopsies during the pandemic compared with the 3 years prior to the pandemic (P = .04).

“There was a slight uptick in 2022, although it remains to be seen whether this trend will continue,” they wrote in their abstract. “While the most common diagnoses in the years leading up to – versus following the start of the pandemic – were similar, there was one clear outlier. The histopathologic diagnosis of pernio spiked in 2020, reflecting the ‘COVID toes’ phenomenon”.

In an interview, Dr. Cordoro said that growths and rashes in children of all ages can, and should, be biopsied, but special considerations are necessary depending on the patient’s age and context. 

“Our data showed that neoplastic conditions were biopsied more often than inflammatory conditions, with an emphasis on lesions that required removal (such as pyogenic granuloma), raised concerns for atypia (nevi), or had implications for systemic management (such as Langerhans cell histiocytosis and graft-versus-host disease). Importantly, cutaneous malignancies in children are rare but do occur, and a high index of suspicion is required when approaching any child with a complex neoplasm or rash.”

Dr. Cordoro characterized the medical decision making and rationale for biopsying skin lesions and rashes in children as “a complex process that involves weighing the risks of the biopsy itself against the benefit of the information it will provide; shared decision-making with the caregivers, the patient (if age-appropriate), and other members of the health care team; age of the child and clinical context; and whether the biopsy can be done at the bedside or requires sedation.”

Based on the study results, Dr. Cordoro said, the rationale to proceed with a biopsy boils down to three main goals: To make or confirm a diagnosis, to make decisions about management, and/or the biopsy itself is therapeutic. 

UCSF dermatopathology fellow Suzanne W. Birmingham, MD, performed the study in collaboration with Dr. Cordoro and UCSF dermatopathologist Thaddeus W. Mully, MD. Additional analyses of this data set are in progress. The researchers reported having no relevant financial disclosures.

Among U.S. high school students, males and non-Whites are at greatest risk for not using sunscreen, a cornerstone of skin cancer prevention, according to results from a systematic review.

“We know that skin cancer is one of the most common malignancies in the world, and sun protection methods such as sunscreen make it highly preventable,” first author Carly R. Stevens, a student at Tulane University, New Orleans, said in an interview. “This study demonstrates the adolescent populations that are most vulnerable to sun damage and how we can help mitigate their risk of developing skin cancer through education methods, such as Sun Protection Outreach Teaching by Students.”  

Ms. Stevens and coauthors presented the findings during a poster session at the annual meeting of the Society for Pediatric Dermatology.

To investigate predictors of sunscreen use among high school students, they searched PubMed, Embase, and Web of Science using the terms (“sunscreen” or “SPF” or “sun protection”) and (“high school” or “teen” or “teenager” or “adolescent”) and limited the analysis to English studies reporting data on sunscreen use in U.S. high school students up to November 2021.

A total of 20 studies were included in the final review. The study populations ranged in number from 208 to 24,645. Of 11 studies that examined gender, all showed increased sunscreen use in females compared with males. Of five studies that examined age, all showed increased sunscreen use in younger adolescents, compared with their older counterparts.

Of four studies that examined the role of ethnicity on sunscreen use, White students were more likely to use sunscreen, compared with their peers of other ethnicities. “This may be due to perceived sun sensitivity, as [these four studies] also showed increased sunscreen use in populations that believed were more susceptible to sun damage,” the researchers wrote in their abstract.

In other findings, two studies that examined perceived self-efficacy concluded that higher levels of sunscreen use correlated with higher self-efficacy, while four studies concluded that high school students were more likely to use sunscreen if their parents encouraged them the wear it or if the parent used it themselves.

“With 40%-50% of ultraviolet damage being done before the age of 20, it’s crucial that we find ways to educate adolescents on the importance of sunscreen use and target those populations who were found to rarely use sunscreen in our study,” Ms. Stevens said.

In one outreach program, Sun Protection Outreach Teaching by Students (SPOTS), medical students visit middle and high schools to educate them about the importance of practicing sun protection. The program began as a collaboration between Saint Louis University and Washington University in St. Louis, but has expanded nationwide. Ms. Stevens described SPOTS as “a great way for medical students to present the information to middle and high school students in a way that is engaging and interactive.”

The researchers reported having no disclosures.

ASHEVILLE, N.C. – Treating atopic dermatitis (AD) in most children­ – and working with parents – might be less dependent on the next, even better therapy than considering facets of poor response and dissatisfaction with treatment, according to a three-member expert panel mulling over strategies at the annual meeting of the Society for Pediatric Dermatology.

In introductory remarks, the three panelists briefly addressed different aspects for controlling AD, including drugs in the pipeline, the potential value of alternative therapies, and whom to blame when compliance is poor.

ASHEVILLE, N.C. – The relative absorption of topical corticosteroids, which can induce cataracts and glaucoma, is 300-fold greater across the eyelids than plantar skin, but pediatric dermatologists need not dwell on this ratio when employing steroids near the eye, according to one of several clinical messages from a pediatric ophthalmologist who spoke at the annual meeting of the Society for Pediatric Dermatology.  

“There is a lot of steroid fear out there, which you can argue is actually harmful in itself, because not treating periorbital eczema is related to a lot of eye problems, including chronic discomfort and the eye rubbing that can cause corneal abrasions and keratoconus,” said Sara Grace, MD, a pediatric ophthalmologist who is on the clinical staff at Duke University, Durham, N.C. She maintains a practice at North Carolina Eye, Ear, Nose, and Throat in Durham.

Although the risks of periorbital steroid absorption are real, a limited course of low potency topical steroids is generally adequate for common periorbital indications, and these appear to be safe.

“There is insufficient evidence to link weak periocular topical corticosteroids such as desonide or hydrocortisone with ocular complications,” said Dr. Grace, suggesting that pediatric dermatologists can be reassured when using these medications at low concentrations.

“Potent periocular steroids have been associated with ocular complications, but this has typically involved exposures over months to years,” Dr. Grace specified.

When topical corticosteroids are applied at high concentrations on the face away from the periorbital area, glaucoma and other feared ophthalmic complications cannot be entirely ruled out, but, again, the risk is low in the absence of “very large quantities” of potent topical agents applied for lengthy periods of time, according to Dr. Grace, basing this observation on case studies.

In children, as in adults, the potential exception is a child with existing ocular disease. In such cases, or in children with risk factors for ocular disease, Dr. Grace recommends referral to an ophthalmologist for a baseline examination prior to a course of topical corticosteroids with the potential of periocular absorption. With a baseline assessment, adverse effects are more easily documented if exposure is prolonged.

The message, although not identical, is similar for use of dupilumab (Dupixent) or other biologics that target the interleukin-13 (IL-13) pathway. The potential for complications cannot be ignored but these are often time-limited and the benefit is likely to exceed the risk in children who have severe atopic dermatitis or other skin conditions for which these treatments are effective.

There are several potential mechanisms by which biologics targeting IL-13 might increase risk of ocular complications, one of which is the role that IL-13 plays in ocular mucus production, regulation of conjunctival goblet cells, and tear production, according to several published reports.

“Up to 30% of children will get some type of eye complication but, fortunately, most of them will not have to stop therapy,” Dr. Grace said. These side effects include conjunctivitis, blepharitis, keratitis, dry eye, and itching, but they are typically manageable. Topical steroids or calcineurin inhibitors can be offered if needed, but many of these conditions will self-resolve. Dr. Grace estimated that less than 1% of patients need to stop treatment because of ophthalmic side effects.

Lesions that obstruct vision

Dr. Grace urged pediatric dermatologists to be aware of the risk for amblyopia in young children with lesions that obstruct vision in one eye. In early development, prolonged obstruction of vision in one eye can alter neural communication with the brain, producing permanent vision impairment.

She explained that clearing the obstructed vision, whether from a capillary hemangioma or any periorbital growth, should be considered urgent to avoid irreversible damage.

Similarly, periorbital port-wine stains associated with Sturge-Weber syndrome, which is primarily a vascular disorder that predisposes children to glaucoma, represents a condition that requires prompt attention. Sturge-Weber syndrome is often but not always identified at birth, but it is a condition for which evaluation and treatment should involve the participation of an ophthalmologist.

Meibomian gland disease is another disorder that is often seen first by a pediatric dermatologist but also requires collaborative management. The challenge is sorting out the underlying cause or causes and initiating a therapy that unclogs the gland without having to resort to incision and drainage.

“Drainage is hard to do and is not necessarily effective,” explained Dr. Grace. While scrubs, warmth, and massage frequently are adequate to unclog the gland – which secretes meibum, a complex of lipids that perform several functions in protecting the eye – therapies specific to the cause, such as Demodex-related blepharitis, chalazions, and styes, might be needed.

Dr. Grace indicated that patience is often needed. The process of unclogging these glands often takes time, but she emphasized that a first-line conservative approach is always appropriate to avoid the difficulty and potential problems of incisions.

In general, these messages are not novel, but they provide a refresher for pediatric dermatologists who do not regularly confront complications that involve the eyes. According to session moderator, Elizabeth Neiman, MD, assistant professor of pediatric dermatology, University of North Carolina at Chapel Hill, the messages regarding topical steroids on the face and the eyes are “important” and worth emphasizing.

“It’s useful to reinforce the point that corticosteroids should be used when needed in the periorbital area [to control skin diseases] if they are used in low concentrations,” Dr. Neiman told this news organization.

Similarly, conjunctivitis and other ocular complications of dupilumab are a source of concern for parents as well as dermatologists. Dr. Neiman indicated that a review of the benefit-to-risk ratio is important when considering these treatments in patients with indications for severe skin disorders.

Dr. Grace and Dr. Nieman have no potential financial conflicts related to this topic.

A rare and devastating pediatric skin condition – severe reactive infectious mucocutaneous eruption (RIME) – may now have an additional, previously undescribed trigger, according to a newly published case report.

Lead author Anna Yasmine Kirkorian, MD, chief of dermatology at Children’s National Hospital in Washington, said she wanted to get the word out in part because it seems like RIME is occurring more frequently. “I do feel like we’re seeing more cases and from a more diverse number of pathogens,” Dr. Kirkorian told this news organization.

There was a decrease in RIME during the early stages of the COVID-19 pandemic when people were isolating more, Dr. Kirkorian said. SARS-CoV-2 has been a trigger for some cases, but she did not find that remarkable, given that respiratory viruses are known RIME precursors. The question is why RIME is being triggered more frequently now that people have essentially gone back to their normal lives, she said.

Dr. Kirkorian and colleagues at Children’s National Hospital and George Washington University, Washington, wrote about a 5-year-old boy with norovirus-triggered RIME in a case report published in Pediatric Dermatology.

RIME – previously known as Mycoplasma pneumoniae–induced rash and mucositis (MIRM) – tends to arise after a viral infection, with upper respiratory viruses such as mycoplasma and Chlamydophila pneumoniae, influenza, and enterovirus among the common triggers. “We think this is actually your own immune system overreacting to a pathogen,” Dr. Kirkorian said in an interview, adding that the mechanism of RIME is still not understood.

While the norovirus discovery was a surprise, it shows that much is still unknown about this rare condition. “I don’t think we know what is usual and what is unusual,” Dr. Kirkorian said.

In this case, the boy swiftly declined, with progressive conjunctivitis, high fever, and rapidly developing mucositis. By the time the 5-year-old got to Children’s National Hospital, he had a spreading, painful rash, including tense vesicles and bullae involving more than 30% of his total body surface area, and areas of denuded skin on both cheeks and the back of his neck.

He had hemorrhagic mucositis of the lips, a large erosion at the urethral meatus, and hemorrhagic conjunctivitis of both eyes with thick yellow crusting on the eyelids.

The clinicians intubated the boy and admitted him to the intensive care unit. He was given a one-time injection of etanercept (25 mg) followed by 8 days of intravenous cyclosporine at a dose of 5 mg per kilogram, divided twice daily, which helped calm the mucositis and stopped the rash from progressing. There is not an accepted protocol or list of evidence-based therapeutics for RIME, Dr. Kirkorian noted.

The severe eye damage required amniotic membrane grafts. The patient was extubated after 9 days but remained in the hospital for a total of 26 days because he needed to receive nutritional support (the mucositis kept him from eating), and for pain control and weaning of sedation.

As the clinicians searched for a potential triggering virus, they came up empty. Results were negative for adenovirus, Epstein Barr virus, cytomegalovirus, herpes simplex, and varicella zoster. But they noted that the child’s household contacts had all been sick a week before with presumed viral gastroenteritis. They decided to run a stool screen and the polymerase chain reaction for norovirus was positive. The boy never had GI symptoms.

Dr. Kirkorian said in the interview that she has seen other RIME cases where a child did not have symptoms associated with the original virus but did have a sudden onset of mucositis.

Although the definition of RIME is evolving, it is defined in part by mucositis in at least two of three areas: the mouth, eyes, and genitals. “Once you have the inflammation of the mucous membranes you should be on alert to think about more serious conditions,” like RIME, said Dr. Kirkorian. “Why does it manifest with the mucositis? I don’t think we know that,” she added.

RIME recurrence has also been vexing for patients, families and clinicians. In May, at the annual Atlantic Dermatology Conference, held in Baltimore, Dr. Kirkorian also discussed an 11-year-old patient who had RIME after SARS-CoV-2 infection early in the pandemic, resulting in a 22-day hospitalization and placement of a peripherally inserted central catheter and a feeding tube. He improved with cyclosporine and was discharged on systemic tacrolimus.

He was fine for several years, until another COVID infection. He again responded to medication. But not long after, an undetermined viral infection triggered another episode of RIME.

Dr. Kirkorian said there is no way to predict recurrence – making a devastating condition all the more worrisome. “Knowing that it might come back and it’s totally haphazard as to what might make it come back – that is very stressful for families,” she said in the interview.

“Some of the most perplexing patients with RIME are those with recurrent disease,” wrote Warren R. Heymann, MD, professor of dermatology and pediatrics at Rowan University, Camden, N.J., wrote in an online column on RIME in the American Academy of Dermatology’s “Dermatology World Insights and Inquiries”.

“Recurrent RIME is of particular interest, given that we could potentially intervene and prevent additional disease,” wrote Camille Introcaso, MD, associate professor of medicine at Rowan University, in response to Dr. Heymann’s remarks. “Although multiple possible mechanisms for the clinical findings of RIME have been proposed, including molecular mimicry between infectious agent proteins and keratinocyte antigens, immune complex deposition, and combinations of medication and infection, the pathophysiology is unknown,” she added.

In the interview, Dr. Kirkorian said that she and colleagues in the Pediatric Dermatology Research Alliance (PeDRA) are trying to assemble more multicenter trials to assess the underlying pathology of RIME, effectiveness of various treatments, and to “find some predictive factors.” Given that RIME is an acute-onset emergency, it is not easy to conduct randomized controlled trials, she added.

Dr. Kirkorian, Dr. Heymann, and Dr. Introcaso report no relevant financial relationships.

He was given a one-time injection of etanercept (25 mg) followed by 8 days of intravenous cyclosporine at a dose of 5 mg per kilogram, divided twice daily, which helped calm the mucositis and stopped the rash from progressing. There is not an accepted protocol or list of evidence-based therapeutics for RIME, Dr. Kirkorian noted.

The severe eye damage required amniotic membrane grafts. The patient was extubated after 9 days but remained in the hospital for a total of 26 days because he needed to receive nutritional support (the mucositis kept him from eating), and for pain control and weaning of sedation.

As the clinicians searched for a potential triggering virus, they came up empty. Results were negative for adenovirus, Epstein Barr virus, cytomegalovirus, herpes simplex, and varicella zoster. But they noted that the child’s household contacts had all been sick a week before with presumed viral gastroenteritis. They decided to run a stool screen and the polymerase chain reaction for norovirus was positive. The boy never had GI symptoms.

Dr. Kirkorian said in the interview that she has seen other RIME cases where a child did not have symptoms associated with the original virus but did have a sudden onset of mucositis.

Although the definition of RIME is evolving, it is defined in part by mucositis in at least two of three areas: the mouth, eyes, and genitals. “Once you have the inflammation of the mucous membranes you should be on alert to think about more serious conditions,” like RIME, said Dr. Kirkorian. “Why does it manifest with the mucositis? I don’t think we know that,” she added.

RIME recurrence has also been vexing for patients, families and clinicians. In May, at the annual Atlantic Dermatology Conference, held in Baltimore, Dr. Kirkorian also discussed an 11-year-old patient who had RIME after SARS-CoV-2 infection early in the pandemic, resulting in a 22-day hospitalization and placement of a peripherally inserted central catheter and a feeding tube. He improved with cyclosporine and was discharged on systemic tacrolimus.

He was fine for several years, until another COVID infection. He again responded to medication. But not long after, an undetermined viral infection triggered another episode of RIME.

Dr. Kirkorian said there is no way to predict recurrence – making a devastating condition all the more worrisome. “Knowing that it might come back and it’s totally haphazard as to what might make it come back – that is very stressful for families,” she said in the interview.

“Some of the most perplexing patients with RIME are those with recurrent disease,” wrote Warren R. Heymann, MD, professor of dermatology and pediatrics at Rowan University, Camden, N.J., wrote in an online column on RIME in the American Academy of Dermatology’s “Dermatology World Insights and Inquiries”.

“Recurrent RIME is of particular interest, given that we could potentially intervene and prevent additional disease,” wrote Camille Introcaso, MD, associate professor of medicine at Rowan University, in response to Dr. Heymann’s remarks. “Although multiple possible mechanisms for the clinical findings of RIME have been proposed, including molecular mimicry between infectious agent proteins and keratinocyte antigens, immune complex deposition, and combinations of medication and infection, the pathophysiology is unknown,” she added.

In the interview, Dr. Kirkorian said that she and colleagues in the Pediatric Dermatology Research Alliance (PeDRA) are trying to assemble more multicenter trials to assess the underlying pathology of RIME, effectiveness of various treatments, and to “find some predictive factors.” Given that RIME is an acute-onset emergency, it is not easy to conduct randomized controlled trials, she added.

Dr. Kirkorian, Dr. Heymann, and Dr. Introcaso report no relevant financial relationships.

A rare and devastating pediatric skin condition – severe reactive infectious mucocutaneous eruption (RIME) – may now have an additional, previously undescribed trigger, according to a newly published case report.

Lead author Anna Yasmine Kirkorian, MD, chief of dermatology at Children’s National Hospital in Washington, said she wanted to get the word out in part because it seems like RIME is occurring more frequently. “I do feel like we’re seeing more cases and from a more diverse number of pathogens,” Dr. Kirkorian told this news organization.

There was a decrease in RIME during the early stages of the COVID-19 pandemic when people were isolating more, Dr. Kirkorian said. SARS-CoV-2 has been a trigger for some cases, but she did not find that remarkable, given that respiratory viruses are known RIME precursors. The question is why RIME is being triggered more frequently now that people have essentially gone back to their normal lives, she said.

Dr. Kirkorian and colleagues at Children’s National Hospital and George Washington University, Washington, wrote about a 5-year-old boy with norovirus-triggered RIME in a case report published in Pediatric Dermatology.

RIME – previously known as Mycoplasma pneumoniae–induced rash and mucositis (MIRM) – tends to arise after a viral infection, with upper respiratory viruses such as mycoplasma and Chlamydophila pneumoniae, influenza, and enterovirus among the common triggers. “We think this is actually your own immune system overreacting to a pathogen,” Dr. Kirkorian said in an interview, adding that the mechanism of RIME is still not understood.

While the norovirus discovery was a surprise, it shows that much is still unknown about this rare condition. “I don’t think we know what is usual and what is unusual,” Dr. Kirkorian said.

In this case, the boy swiftly declined, with progressive conjunctivitis, high fever, and rapidly developing mucositis. By the time the 5-year-old got to Children’s National Hospital, he had a spreading, painful rash, including tense vesicles and bullae involving more than 30% of his total body surface area, and areas of denuded skin on both cheeks and the back of his neck.

He had hemorrhagic mucositis of the lips, a large erosion at the urethral meatus, and hemorrhagic conjunctivitis of both eyes with thick yellow crusting on the eyelids.

The clinicians intubated the boy and admitted him to the intensive care unit. He was given a one-time injection of etanercept (25 mg) followed by 8 days of intravenous cyclosporine at a dose of 5 mg per kilogram, divided twice daily, which helped calm the mucositis and stopped the rash from progressing.
