The guidelines, published in the Journal of the American Academy of Dermatology, focus on treatment for adults, and follow the release of other AAD-NPF guidelines on biologics for psoriasis, psoriasis-related comorbidities, pediatric psoriasis, and phototherapy in 2019, and earlier this year, guidelines for systemic nonbiologic treatments. The latest guidelines’ section on topical treatment outlines evidence for the efficacy, effectiveness, and adverse events related to topical steroids, topical tacrolimus and pimecrolimus, vitamin D analogues, tazarotene, moisturizers, salicylic acid, anthralin, coal tar, combinations with biologic agents, and combinations with nonbiologic treatments (methotrexate, cyclosporine, acitretin, and apremilast).

The guidelines noted the “key role” of topical corticosteroids in treating psoriasis “especially for localized disease,” and include a review of the data on low-, moderate-, high-, and ultrahigh-potency topical steroids for psoriasis.

In general, all topical steroids can be used in combination with biologics, according to the guidelines, but the strongest recommendations based on the latest evidence include the addition of an ultra-high potency topical corticosteroid to standard dose etanercept for 12 weeks. Currently, 11 biologics are approved by the Food and Drug Administration for the treatment of psoriasis.

In addition, “while not FDA approved for psoriasis, the topical calcineurin inhibitors tacrolimus and pimecrolimus are often employed in the treatment of psoriasis,” can be helpful for “thinner skin such as facial and intertriginous areas,” and can be steroid sparing when used for more than 4 weeks, according to the guidelines.

Don’t discount the role of patient preferences when choosing topical treatments, the authors noted. “The optimal vehicle choice is the one the patient is mostly likely to use.”

The guidelines also address the evidence for effectiveness, and adverse events in the use of several alternative medicines for psoriasis including traditional Chinese medicine, and the herbal therapies aloe vera and St. John’s wort, as well as the potential role of dietary supplements including fish oil, vitamin D, turmeric, and zinc in managing psoriasis, and the potential role of a gluten-free diet.

In general, research on the efficacy, effectiveness, and potential adverse effects of these strategies are limited, according to the guidelines, although many patients express interest in supplements and herbal products. For example, “Many patients ask about the overall role of vitamin D in skin health. Rather than adding oral vitamin D supplementation, topical therapy with vitamin D agents is effective for the treatment of psoriasis,” the authors noted.

In addition, they noted that mind/body strategies, namely hypnosis and stress reduction or meditation techniques, have been shown to improve symptoms and can be helpful for some patients, but clinical evidence is limited.

The guidelines also addressed methods for assessing disease severity in psoriasis. They recommended using body surface area (BSA) to assess psoriasis severity and patient response to treatment in the clinical setting. However, BSA is a provider assessment tool that “does not take into account location on the body, clinical characteristics of the plaques, symptoms, or quality of life issues,” the authors noted. The Psoriasis Area and Severity Index (PASI) measures erythema, induration, and scaling and is more suited to assessing psoriasis severity and response to treatment in clinical trials rather than in practice, they said.

Prior AAD guidelines on psoriasis were published more than 10 years ago, and major developments including the availability of new biologic drugs and new data on comorbidities have been recognized in the past decade, working group cochair and author of the guidelines Alan Menter, MD, said in an interview.

The key game-changers from previous guidelines include the full section published on comorbidities plus the development of two new important cytokine classes: three IL-17 drugs and three new IL-23 drugs now available for moderate to severe psoriasis, said Dr. Menter, chairman of the division of dermatology at Baylor University Medical Center, Dallas.

Barriers to implementing the guidelines in practice may occur when “third party payers make the decision on which of the 11 biologic drugs now approved for moderate to severe psoriasis should be used,” he noted.

As for next steps in psoriasis studies, “new biomarker research is currently underway,” Dr. Menter said. With 11 biologic agents new formally approved by the FDA for moderate to severe psoriasis, the next steps are to determine which drug is likely to be the most appropriate for each individual patient.

Dr. Menter disclosed relationships with multiple companies that develop and manufacture psoriasis therapies, including Abbott Labs, AbbVie, Amgen, Eli Lilly and Company, Galderma USA, Janssen Pharmaceuticals, LEO Pharma US, Menlo Therapeutics, and Novartis. The updated guidelines were designed by a multidisciplinary work group of psoriasis experts including dermatologists, a rheumatologist, a cardiologist, and representatives from a patient advocacy organization.

Treatment of psoriasis with biologics was associated with a reduced risk of developing psoriatic arthritis compared with conventional disease-modifying antirheumatic drugs (DMARDs), in a single center retrospective analysis in Argentina that followed patients for almost 2 decades.

About 30%-40% of patients with psoriasis go on to develop psoriatic arthritis (PsA), usually on average about 10 years after the onset of psoriasis. One potential mechanism of PsA onset is through enthesitis, which has been described at subclinical levels in psoriasis.

“It could be speculated that treatment with biologics in patients with psoriasis could prevent the development of psoriatic arthritis, perhaps by inhibiting the subclinical development of enthesitis,” Luciano Lo Giudice, MD, a rheumatology fellow at Hospital Italiano de Buenos Aires, said during his presentation at the virtual annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.

Although these results do not prove that treatment of the underlying disease delays progression to PsA, it is suggestive, and highlights an emerging field of research, according to Diamant Thaçi, MD, PhD, professor of medicine at University Hospital Schleswig-Holstein, Germany, who led a live discussion following a prerecorded presentation of the results. “We’re going in this direction – how can we prevent psoriatic arthritis, how can we delay it. We are just starting to think about this,” Dr. Thaçi said in an interview.

The researchers examined medical records of 1,626 patients with psoriasis treated at their center between 2000 and 2019, with a total of 15,152 years of follow-up. Of these patients, 1,293 were treated with topical medication, 229 with conventional DMARDs (methotrexate in 77%, cyclosporine in 13%, and both in 10%), and 104 with biologics, including etanercept (34%), secukinumab (20%), adalimumab (20%), ustekinumab (12%), ixekizumab (9%), and infliximab (5%).

They found that 11% in the topical treatment group developed PsA, as did 3.5% in the conventional DMARD group, 1.9% in the biologics group, and 9.1% overall. Treatment with biologics was associated with a significantly lower odds of developing PsA compared with treatment with conventional DMARDs (3 versus 17.2 per 1,000 patient-years; incidence rate ratio [IRR], 0.17; P = .0177). There was a trend toward reduced odds of developing PsA among those on biologic therapy compared with those on topicals (3 versus 9.8 per 1,000 patient-years; IRR, 0.3; P = .0588).

The researchers confirmed all medical encounters using electronic medical records and the study had a long follow-up time, but was limited by the single center and its retrospective nature. It also could not associate reduced risk with specific biologics.

The findings probably reflect the presence of subclinical PsA that many clinicians don’t see, according to Dr. Thaçi. While a dermatology practice might find PsA in 2% or 3%, or at most, 10% of patients with psoriasis, “in our department it’s about 50 to 60 percent of patients who have psoriatic arthritis, because we diagnose it early,” he said.

He found the results of the study encouraging. “It looks like some of the biologics, for example IL [interleukin]-17 or even IL-23 [blockers] may have an influence on occurrence or delay the occurrence of psoriatic arthritis.”

Dr. Thaçi noted that early treatment of skin lesions can increase the probability of longer remissions, especially with IL-23 blockers. Still, that’s no guarantee the same would hold true for PsA risk. “Skin is skin and joints are joints,” Dr. Thaçi said.

Dr. Thaçi and Dr. Lo Giudice had no relevant financial disclosures.

Belatedly, the disproportionate impact of COVID-19 on patients of color is getting attention. By now, we’ve read the headlines. Black people in the United States make up about 13% of the population but account for almost three times (34%) as many deaths. This story repeats – in other countries and in other minority communities.

Early detection is critical both to initiate supportive care and to isolate affected individuals and limit spread. Skin manifestations of COVID-19, especially those that occur early in the disease (eg, vesicular eruptions) or have prognostic significance (livedo, retiform purpura, necrosis), are critical to this goal of early recognition.

In this context, a recent systematic literature review looked at all articles describing skin manifestations associated with COVID-19. The investigators identified 46 articles published between March and May 2020 which included a total of 130 clinical images.

The following findings from this study are striking:

• 92% of the published images of COVID-associated skin manifestations were in I-III.
• Only 6% of COVID skin lesions included in the articles were in patients with skin type IV.
• None showed COVID skin lesions in skin types V or VI.
• Only six of the articles reported race and ethnicity demographics. In those, 91% of the patients were White and 9% were Hispanic.

These results reveal a critical lack of representative clinical images of COVID-associated skin manifestations in patients of color. This deficiency is made all the more egregious given the fact that patients of color, including those who are Black, Latinx, and Native American, have been especially hard hit by the COVID-19 pandemic and suffer disproportionate disease-related morbidity and mortality.
 

As the study authors point out, skin manifestations in people of color often differ significantly from findings in White skin (for example, look at the figure depicting the rash typical of Kawasaki disease in a dark-skinned child compared with a light-skinned child). It is not a stretch to suggest that skin manifestations associated with COVID-19 may look very different in darker skin.

These investigators have identified a damning lack of images of COVID-19–associated skin manifestations in patients with darker skin. This isn’t a new phenomenon. Almost half of dermatologists feel that they’ve had insufficient exposure to skin disease in darker skin types. Skin of color remains underrepresented in medical journals.

Like other forms of passive, institutional racism, this deficiency will only be improved if dermatologists and dermatology publications actively seek out COVID-associated skin manifestations in patients of color and prioritize sharing these images. A medical student in the United Kingdom has gotten the ball rolling, compiling a handbook of clinical signs in darker skin types as part of a student-staff partnership at St. George’s Hospital and the University of London. At this time, Mind the Gap is looking for a publisher.

Like other forms of passive, institutional racism, this deficiency will only be improved if dermatologists and dermatology publications actively seek out COVID-associated skin manifestations in patients of color and prioritize sharing these images. A medical student in the United Kingdom has gotten the ball rolling, compiling a handbook of clinical signs in darker skin types as part of a student-staff partnership at St. George’s Hospital and the University of London. At this time, Mind the Gap is looking for a publisher.

An erythematous rash was the most common cutaneous manifestation in patients with COVID-19, followed by chilblain-like lesions and urticaria-like lesions in a systematic review of mostly European studies.

Qing Zhao, MD, Xiaokai Fang, MD, and their colleagues at the Shandong Provincial Hospital for Skin Diseases & Shandong Provincial Institute of Dermatology and Venereology, in Jinan, China, reported the results of a literature review of 44 articles published through May 2020 that included 507 patients with cutaneous manifestations of COVID-19. The review was published in the Journal of The European Academy of Dermatology and Venereology.

Nearly all of the patients (96%) were from Europe, and more than half were women (60%), with an average age of 49 years. Most patients had multiple skin symptoms, with the most common being erythema (44%), chilblain-like lesions (20%), urticaria-like lesions (16%), vesicular manifestations (13%), livedo/necrosis (6%), and petechiae (almost 2%). The authors described erythema as being present in specific sites, such as the trunk, extremities, flexural regions, face, and mucous membranes. Slightly less than half of all patients had significant pruritus.

Data on systemic COVID-19 symptoms were available for 431 patients and included fever in about two-thirds of patients and cough in almost 70%, with dyspnea in almost half of patients. Almost 60% had fatigue, and almost 60% had asthenia. Information about the onset of skin symptoms was available in 88 patients; of these patients, lesions were seen an average of almost 10 days after systemic symptoms appeared and, in almost 15%, were the first symptoms noted.

Histopathologic exams were done for only 23 patients and, in all cases, showed “inflammatory features without specific pathological changes, such as lymphocyte infiltration.” In one study, reverse transcription polymerase chain reaction testing of skin biopsy specimens tested negative for SARS-CoV-2.

Expression of ACE2, the receptor of SARS-CoV-2, in the skin was evaluated in six of the studies. “Higher ACE2 expression was identified in keratinocytes, mainly in differentiating keratinocytes and basal cells compared to the other cells of skin tissues,” the authors wrote. These results were confirmed with immunohistochemistry, which, they said, found “ACE2-positive keratinocytes in the stratum basal, the stratum spinosum, and the stratum granulosum of epiderma.” They added that this provides evidence “for percutaneous infection or the entry of virus into patients through skin tissues,” but cautioned that more research is needed.

The authors acknowledged that there are still many unanswered questions about COVID-19, and that more clinical data and research are needed, to improve the understanding of the cutaneous manifestations associated with COVID-19.

Pathogenesis of different cutaneous manifestations may be different, Dr. Femia said. For example, urticaria and morbilliform eruption were described by the authors of the review as more benign eruptions, but pathogenesis may differ from that of so-called COVID toes and from the pathogenesis of purpura and ulcerations seen in patients with more severe disease, she noted. It is plausible, she added, that purpura and ulcerations may be a “direct invasion of SARS-CoV-2 into endothelial cells,” which creates secondary processes “that ultimately destroy the skin.”

Urticaria and morbilliform eruptions, on the other hand, “are more simply that the immune system is recognizing COVID, and in doing so, is also recognizing some antigens in the skin and creating a hypersensitive response to the skin” and has “nothing to do with the SARS-CoV-2 virus actually being in that location,” she said.

It is important to differentiate between patients who have skin manifestations attributed to COVID-19 and those with manifestations independent of COVID-19, which is difficult, Dr. Femia noted. A patient with COVID-19 and a cutaneous manifestation may be having a reaction to a medication. “It’s important to have a critical eye and to remember that, when we see these manifestations, we should always be investigating whether there was an alternative cause so that we can better learn what exactly we should be attributing to this infection,” she said

Adam Friedman, MD, professor and interim chair of dermatology at George Washington University, Washington, said the authors of the review had presented interesting work, but made some “assumptions that need to be proven.” Dr. Friedman also was not involved in the research, but agreed in an interview with the assessment that it is unlikely SARS-CoV-2 would penetrate the skin. While some viruses – such as the poxvirus that causes molluscum contagiosum and the herpes simplex virus – invade keratinocytes specifically, there is a particular clinical phenotype that results that is associated with changes in the epidermis. However, “the skin manifestations of COVID-19 do not fit with direct skin invasion, [but] rather the immune response to systemic disease,” he said.

“[I]n terms of systemic invasion through the skin, it is possible, but this study certainly doesn’t show that. The presence/expression of ACE2 in the epidermis doesn’t translate to route of infection,” Dr. Friedman said..

The study received financial support from Shandong First Medical University, the Innovation Project of Shandong Academy of Medical Sciences and the Shandong Province Taishan Scholar Project. The authors report no relevant financial disclosures. Dr. Femia and Dr. Friedman had no relevant financial disclosures.

Pediatric melanoma remains a rare diagnosis – representing just 1%-4% of all melanomas – and it continues to be poorly understood.

“There are many questions about its biology, histopathology, and clinical behavior,” Teresa S. Wright, MD, said during the virtual annual meeting of the Society for Pediatric Dermatology. “This diagnosis can be very difficult to establish. These lesions can be very unusual and require several different expert opinions to arrive at a diagnosis. Oftentimes, there may be an initial misdiagnosis or disagreement about diagnosis. This frequently results in a delay of treatment.”

Dr. Wright, chief of pediatric dermatology at LeBonheur Children’s Hospital and associate professor of dermatology at the University of Tennessee Health Science Center, Memphis, added that once a diagnosis of pediatric melanoma has been established, things don’t get any easier because of the lack of evidence-based guidelines for management. “There are really no standard recommendations regarding the workup, treatment, or follow-up for these patients,” she said.



Referral Clinic Launched

In 2016, under the direction of Alberto Pappo, MD, director of the solid tumor division at St. Jude Children’s Research Hospital in Memphis, Dr. Wright and several colleagues at St. Jude and the University of Tennessee Health Science Center, launched a 2-day twice-yearly multidisciplinary Pediatric and Adolescent Melanoma Referral Clinic, in an effort to offer a second opinion and guidance for management of complex cases. “As a group, we address questions surrounding the diagnosis and pathology of the patient’s lesion, as well as therapy and follow-up for each individual patient,” Dr. Wright said.

Members of the clinic team include a pediatric oncologist, an adult oncologist, and a surgical oncologist (all with melanoma expertise); a pediatric surgeon, a pediatric dermatologist, a pediatric radiologist, a pathologist, and a nursing team, which includes a pediatric nurse practitioner, three registered nurses, and other support staff, including those that provide genetic counseling and child life specialists. To be eligible for the clinic, which typically is scheduled in April and November every year, patients must be no older than 21 years, must be referred by a physician, and must have a diagnosis of melanoma or Spitzoid melanoma, not including ocular melanoma. They must be currently undergoing treatment or followed by a physician who requests or supports a consult to optimize clinical management of the patient. St. Jude foots the bill for all travel, housing, and meal expenses. All pertinent materials are collected in advance of the 2-day clinic, including medical records, lab results, histology slides, tissue samples, and radiographic studies. The pathologist performs an initial review of the histology slides and additional genomic studies are performed based on the pathologist’s diagnosis.

Patients typically arrive on a Wednesday evening and have their first clinic visit Thursday morning. First, the oncology team performs a thorough history and physical examination, then Dr. Wright performs a thorough skin examination and a professional photographer captures images of relevant skin lesions. That afternoon, members of the multidisciplinary team meet to review each patient’s entire course, including previous surgeries and any medical therapies.

“We review their pathology, including histology slides and results of any genomic studies,” Dr. Wright said. “We also review all the radiographic studies they’ve had, which may include plain films, CT scans, PET scans, MRIs, and ultrasounds. Then we form a consensus opinion regarding a diagnosis. Sometimes we feel a change in diagnosis is warranted.” For example, she added, “we have had a number of patients referred to us with an initial diagnosis of Spitzoid melanoma where, after review, we felt that a diagnosis of atypical Spitzoid tumor was more appropriate for them. We also talk about any treatment they’ve had in the past and decide if any additional surgical or medical treatment is indicated at this time. Lastly, we make recommendations for follow-up or surveillance.”

On Thursday evening, the clinic sponsors a casual dinner for families, which features an educational presentation by one or more faculty members. Topics covered in the past include sun protection, melanoma in children, and an overview of melanoma research.

The next morning, each family meets with the panel of specialists. “The team members introduce themselves and describe their roles within the team, and family members introduce themselves and tell their child’s story. “Then, each team member describes their findings and gives their overall assessment. The family receives recommendations for any additional testing, therapy, and follow-up, and the patient and family’s questions are answered.”

Families are also offered the opportunity to participate in research. “They can donate samples to a tissue bank, and patients may qualify for future clinical trials at St. Jude Children’s Research Hospital,” Dr. Wright said.

To date, 20 female and 18 male patients have traveled to the Pediatric and Adolescent Melanoma Referral Clinic from 21 states and Puerto Rico for assessment and consultation. They ranged in age from 6 months to 18 years, and their average age is 9 years. Members of the clinic team have seen 13 patients with a diagnosis of Spitzoid melanoma, 10 with malignant melanoma, 8 with atypical melanocytic neoplasm, 3 with congenital melanoma, 3 with atypical Spitz tumor, and 1 with congenital melanocytic nevus.

The median age at diagnosis was 12 years for malignant melanoma and 9 years for Spitzoid melanoma; and the male to female ratio is 7:3 for malignant melanoma and 4:9 for Spitzoid melanoma. These are the patients who have come to the multidisciplinary clinic, these specialists see other patients with a diagnosis of pediatric or adolescent melanoma at other times of the year, Dr. Wright noted.

A common refrain she hears from pediatric melanoma patients and their families is that the initial skin lesion appears to be unremarkable. “Many times, this is a skin-colored or pink papule, which starts out looking very much like a molluscum or a wart or an insect bite, or something else that nobody’s worried about,” Dr. Wright said. “But over time, something happens, and the common factor is rapid growth. Time and again when I ask parents, ‘What changed? What got your attention?’ The answer is nearly always rapid growth.”

She emphasized that patients frequently arrive at the clinic with multiple opinions about their diagnosis. “It’s not unusual for a significant amount of time to pass between the initial biopsy and the final diagnosis,” she said. “Given the lack of evidence-based guidelines for children, a delay in diagnosis can make decisions about management even more difficult. Because pediatric melanoma is so rare, and there are no standard guidelines for management, there’s a major lack of consistency in terms of how patients are evaluated, treated, and followed.”

Dr. Wright said the team’s goals are to continue the biannual clinic and collect more data and tissue samples for further genomic studies on pediatric melanoma. “Ultimately, we would like to hold a consensus summit meeting of experts to develop and publish evidence-based guidelines for the management of pediatric and adolescent melanoma.”

Members of the clinic team have seen 13 patients with a diagnosis of Spitzoid melanoma, 10 with malignant melanoma, 8 with atypical melanocytic neoplasm, 3 with congenital melanoma, 3 with atypical Spitz tumor, and 1 with congenital melanocytic nevus.

The median age at diagnosis was 12 years for malignant melanoma and 9 years for Spitzoid melanoma; and the male to female ratio is 7:3 for malignant melanoma and 4:9 for Spitzoid melanoma. These are the patients who have come to the multidisciplinary clinic, these specialists see other patients with a diagnosis of pediatric or adolescent melanoma at other times of the year, Dr. Wright noted.

A common refrain she hears from pediatric melanoma patients and their families is that the initial skin lesion appears to be unremarkable. “Many times, this is a skin-colored or pink papule, which starts out looking very much like a molluscum or a wart or an insect bite, or something else that nobody’s worried about,” Dr. Wright said. “But over time, something happens, and the common factor is rapid growth. Time and again when I ask parents, ‘What changed? What got your attention?’ The answer is nearly always rapid growth.”

She emphasized that patients frequently arrive at the clinic with multiple opinions about their diagnosis. “It’s not unusual for a significant amount of time to pass between the initial biopsy and the final diagnosis,” she said. “Given the lack of evidence-based guidelines for children, a delay in diagnosis can make decisions about management even more difficult. Because pediatric melanoma is so rare, and there are no standard guidelines for management, there’s a major lack of consistency in terms of how patients are evaluated, treated, and followed.”

Dr. Wright said the team’s goals are to continue the biannual clinic and collect more data and tissue samples for further genomic studies on pediatric melanoma. “Ultimately, we would like to hold a consensus summit meeting of experts to develop and publish evidence-based guidelines for the management of pediatric and adolescent melanoma.”

Dr. Wright reported having no relevant disclosures.

The Wood’s lamp revealed a coral-red fluorescence in the interdigital spaces, which led to a diagnosis of erythrasma.

The coral-red fluorescence seen under the Wood’s lamp is due to porphyrins produced by Corynebacterium minutissimum. The organism invades the stratum corneum where it proliferates and causes erythrasma. Erythrasma typically appears as delineated, dry, red-brown patches in intertriginous areas, such as the axilla, groin, interdigital spaces, intergluteal cleft, perianal skin, and inframammary area.

Erythrasma affects 4% of the population; risk factors include poor hygiene, hyperhidrosis, obesity, warm climate, diabetes, and an immunocompromised state. The differential diagnosis for a pruritic rash between the toes includes tinea pedis and contact dermatitis.

First-line management of erythrasma includes both nonpharmacologic and pharmacologic modalities. Good hygiene and, depending on the area affected, loose-fitting cotton undergarments can help treat and prevent erythrasma.

Topical 2% miconazole bid for 2 weeks has resulted in clearance rates as high as 88%. Its affordable price, over-the-counter availability, and lack of adverse effects make miconazole a reasonable choice. It is also a smart treatment choice when erythrasma is coexisting with tinea because it can treat both conditions.

Topical 1% clindamycin or 2% erythromycin solution or gel bid for 2 weeks also can be used to treat the condition. However, given that topical antibiotics are more expensive than single-dose oral treatment and are no better than the oral formulations of these antibiotics, clarithromycin 1 g taken once orally may be preferred. Our patient was treated with a single dose of clarithromycin 1 g. At follow-up, her erythrasma was clear.

When children and adolescents first present to George Hightower, MD, PhD, with suspected primary hyperhidrosis, he tries to gauge their level of impairment and distress.

Miyuki-3

“I ask my patients directly: ‘Does this get in the way of doing things you enjoy?’ ” Dr. Hightower said during the virtual Pediatric Dermatology 2020: Best Practices and Innovations Conference. If they say yes, he then asks, “‘What are those things that it gets in the way of?’ Also, so that I can develop a rapport with them, I ask, ‘Is it causing you to view yourself negatively?’ I also ask them how they anticipate treatment is going to change that.”

Dr. Hightower, of the departments of dermatology and pediatrics, University of California, San Diego, and a pediatric dermatologist at Rady Children’s Hospital, defined focal primary hyperhidrosis as focal, visible, excessive sweating for at least 6 months without an apparent cause, plus at least two of the following characteristics: bilateral and relatively symmetric, sweating that impairs daily activities, onset before age 25, at least one episode per week, family history of idiopathic hyperhidrosis, and focal sweating that stops during sleep.

“Based on their prominence in the popular media, armpits relative to body surface area play an oversized role in our patients’ perception of well-being,” he said. “Most of all, patients’ concerns regarding their armpits include one more of the following symptoms: smelly, sweaty, red, and itchy or painful.”

The differential diagnosis for disorders of the axilla includes irritant/contact dermatitis, folliculitis, seborrheic dermatitis, hyperhidrosis, and hidradenitis suppurativa.

Topical antiperspirants are the preferred initial treatment. “They’re widely available, inexpensive, and well-tolerated therapies,” Dr. Hightower said. Most commercially available antiperspirants contain low-dose aluminum or other metal that keeps the sweat gland ducts from opening.

“Most patients referred to me have failed to improve with over-the-counter antiperspirants or aluminum chloride 20%,” he said. “We start by reviewing the appropriate use of aluminum chloride 20%. If they’re using it appropriately and fail to achieve adequate control, I open the discussion to use glycopyrronium tosylate cloth 2.4%, applied daily. This can be cost prohibitive or not covered by insurance.” Other options include glycopyrrolate 1-6 mg daily and microwave-based procedural intervention.

In a post hoc analysis, researchers examined the efficacy and safety findings by age from two phase three randomized, controlled trials of glycopyrronium tosylate in pediatric primary axillary hyperhidrosis (Pediatr Dermatol. 2019 Jan-Feb;36[1]:89-99). It was well tolerated in the 19 patients aged 9-16 years. “No patients discontinued from the study in this age group [because of] symptomatology,” said Dr. Hightower, who was not involved with the study. “The concerns related to this medication are related to anticholinergic effects such as blurry vision and dry mouth, but overall, randomized clinical trial data support the benefit of this medication in helping patients improve the symptoms of hyperhidrosis.”

In an earlier study, researchers retrospectively studied children with hyperhidrosis who were treated with a mean dosage of 2 mg glycopyrronium tosylate daily (J Am Acad Dermatol 2012 Nov;67[5]:918-23). The average age of patients was 15 years. Most (90%) experienced some improvement and 71% of those who responded saw major improvement. This occurred within hours of administration and disappeared within a day of discontinuation. The two most common side effects were dry mouth (26%) and dry eyes (10%). More worrisome side effects were associated with higher dosing, including blurring of vision (3%) and sensation of palpitations (3%).

When patients return for their first follow-up appointment after starting a treatment plan, Dr. Hightower revisits their level of impairment and distress with hyperhidrosis. “I ask, ‘Remember that activity that you were doing before that this was getting in the way of? Are you doing that more? Do you feel like you can do that in a way that you weren’t able to do before, whether it’s playing an instrument or spending time with friends?’ ”

He also sets expectations with patients and their families with comments such as, “If this treatment does not work for you after 2 months, the next option I would consider is ...” and, “for most people there is no cure, but treatment is helpful.” He also emphasizes the importance of follow-up care, so they “come back to assess the next steps.”

Dr. Hightower reported having no financial disclosures.

The top three contact allergens in patients younger than 18 years of age are hydroperoxides of linalool, nickel sulfate, and methylisothiazolinone, according to an analysis of data from the Pediatric Allergic Contact Dermatitis Registry.

The registry is the first multicenter prospective database in the United States with a focus on pediatric allergic contact dermatitis. JiaDe (Jeff) Yu, MD, a dermatologist at Massachusetts General Hospital, Boston, was awarded a Dermatology Foundation Career Development Grant and formed the registry in 2018 “in an effort to gain a better understanding of allergic contact dermatitis in children,” Idy Tam, MS, said during the virtual annual meeting of the Society for Pediatric Dermatology. “There is currently limited data regarding the pediatric allergic contact dermatitis in the U.S., despite as many as 20% of children having allergic contact dermatitis.”

To date, the Pediatric Allergic Contact Dermatitis Registry consists of 10 academic medical centers with high volume pediatric patch testing across the United States: Massachusetts General Hospital, Boston; Brigham and Women’s Hospital, Boston; the University of Missouri–Columbia; Stanford (Calif.) University; the Medical University of South Carolina, Charleston; Texas Children’s Hospital, Houston; Northwestern University, Chicago; Emory University, Atlanta; Washington University, St. Louis; and the University of California, San Diego.

For the current analysis, Ms. Tam, a research fellow in the department of dermatology at Massachusetts General Hospital, and colleagues collected data on 218 patients under age 18 who were referred for an evaluation of allergic contact dermatitis at one of the 10 participating sites between January 2016 and June 2020.

The mean age of children at the time of their patch testing was 10 years, 62% were girls, and 66% had a history of atopic dermatitis (AD). Most (75%) were White, 14% were Black, 6% were Asian, the rest were from other racial backgrounds. The distribution of dermatitis varied; the top five most commonly affected sites were the face (62%), arms (35%), legs (29%), hands (27%), and neck (20%).

Ms. Tam reported that the mean number of allergens patch tested per child was 78. In all, 81% of children had one or more positive patch test reactions, with a similar rate among those with and without a history of AD (80% vs. 82%, respectively; P = .21). The five most common allergens were hydroperoxides of linalool (22%), nickel sulfate (19%), methylisothiazolinone (17%), cobalt chloride (13%), and fragrance mix I (12%).

The top two treatments at the time of patch testing were a topical corticosteroid (78%) and a topical calcineurin inhibitor (26%).

“This study has allowed for the increased collaboration among dermatologists with expertise in pediatric dermatology and allergic contact dermatitis,” concluded Ms. Tam, a fourth-year medical student at Tufts University, Boston. “We continue to actively seek further collaboration with a goal of creating the most comprehensive pediatric allergic contact dermatitis registry, which can improve our understanding of this condition in children and hopefully guide future research in this field.”

The work was recognized as one of the top poster abstracts at the meeting. The researchers reported having no relevant disclosures.

The proportion of Americans who’ve experienced two or more sunburns in the past year rose significantly during a recent 10-year period, for reasons that are unclear, Nicole L. Bolick, MD, reported at the virtual annual meeting of the American Academy of Dermatology.

On the plus side, utilization of indoor tanning plunged in the United States during the same period, a statistic worth celebrating as a public health and legislative success, noted Dr. Bolick, who was at the Harvard T.H. Chan School of Public Health, Boston, when she conducted her study and is now at East Carolina University, Greenville, N.C.

More good news: Her analysis of data from 67,471 nationally representative participants in the Centers for Disease Control and Prevention’s National Health Information Survey for the years 2005, 2010, and 2015 also demonstrated that the public’s adoption of several key skin cancer prevention behaviors is on the rise, although she added that rates clearly remain suboptimal.

For example, the proportion of Americans who practice sun avoidance climbed from 31.7% in 2005 to 35.5% in 2010, and 36.8% in 2015 in a multivariate logistic regression analysis adjusted for demographics, alcohol use, location, smoking status, education level, health insurance, and family and personal history of skin cancer.

Similarly, the use of sunscreen always or most of the time when outdoors for more than 1 hour on a warm, sunny day rose from an adjusted 31.5% in 2005 to 33.1% in 2010 and to 34.3% in 2015.

Also, sun protective clothing – long pants, hats, and/or long-sleeved shirts – was utilized always or most of the time by 35.9% of respondents in 2005, 38.4% in 2010, and 37.2% in 2015.

In 2005, 19% of Americans reported having a lifetime history of a physician-performed full body skin examination. The prevalence of this secondary skin cancer prevention measure rose to 22.4% in 2010 and remained the same in 2015.

In the 2005 national survey, 14.1% of respondents reported engaging in indoor tanning within the past year. This figure dropped to 6.2% in 2010 and fell further to 4.1% in 2015.

A history of two or more sunburns within the past year was reported by 18.2% of subjects in 2005, by 21.1% in 2010, and by 19.9% in 2015. It’s unclear whether this unwelcome phenomenon is due to inadequate use of sun protection or increased awareness of the link between sun exposure and skin cancer, with a resultant increase in reporting of sunburns. The influence of climate change is another possible explanation worthy of further study, according to Dr. Bolick.

She reported having no financial conflicts regarding her study, conducted free of commercial support.

On the plus side, utilization of indoor tanning plunged in the United States during the same period, a statistic worth celebrating as a public health and legislative success, noted Dr. Bolick, who was at the Harvard T.H. Chan School of Public Health, Boston, when she conducted her study and is now at East Carolina University, Greenville, N.C.

More good news: Her analysis of data from 67,471 nationally representative participants in the Centers for Disease Control and Prevention’s National Health Information Survey for the years 2005, 2010, and 2015 also demonstrated that the public’s adoption of several key skin cancer prevention behaviors is on the rise, although she added that rates clearly remain suboptimal.

For example, the proportion of Americans who practice sun avoidance climbed from 31.7% in 2005 to 35.5% in 2010, and 36.8% in 2015 in a multivariate logistic regression analysis adjusted for demographics, alcohol use, location, smoking status, education level, health insurance, and family and personal history of skin cancer.

Similarly, the use of sunscreen always or most of the time when outdoors for more than 1 hour on a warm, sunny day rose from an adjusted 31.5% in 2005 to 33.1% in 2010 and to 34.3% in 2015.

Also, sun protective clothing – long pants, hats, and/or long-sleeved shirts – was utilized always or most of the time by 35.9% of respondents in 2005, 38.4% in 2010, and 37.2% in 2015.

In 2005, 19% of Americans reported having a lifetime history of a physician-performed full body skin examination. The prevalence of this secondary skin cancer prevention measure rose to 22.4% in 2010 and remained the same in 2015.

In the 2005 national survey, 14.1% of respondents reported engaging in indoor tanning within the past year. This figure dropped to 6.2% in 2010 and fell further to 4.1% in 2015.

A history of two or more sunburns within the past year was reported by 18.2% of subjects in 2005, by 21.1% in 2010, and by 19.9% in 2015. It’s unclear whether this unwelcome phenomenon is due to inadequate use of sun protection or increased awareness of the link between sun exposure and skin cancer, with a resultant increase in reporting of sunburns. The influence of climate change is another possible explanation worthy of further study, according to Dr. Bolick.

She reported having no financial conflicts regarding her study, conducted free of commercial support.

Cutaneous lupus erythematosus (CLE) is present in 25% of patients with systemic lupus at the time of diagnosis, but it can also occur in up to 85% of cases at some point in their disease course, Eveline Y. Wu, MD, said during the virtual annual meeting of the Society for Pediatric Dermatology.

“CLE can also occur without any systemic disease,” said Dr. Wu, associate professor of pediatrics at the University of North Carolina at Chapel Hill. “It’s been shown that the risk of developing systemic lupus differs according to the type of skin involvement, meaning that cutaneous lupus can be classified into acute, subacute, chronic, and intermittent forms.”

Malar rash is the prototypical acute cutaneous lesion and is associated with active systemic lupus erythematosus (SLE) and anti–double stranded DNA antibody positivity, while discoid lupus erythematosus is the most common chronic lesion. “A small percentage of patients with discoid lupus can develop systemic lupus, particularly when the lesions are more disseminated,” said Dr. Wu, who specializes in pediatric rheumatology as well as allergy and immunology.

In the American College of Rheumatology’s 1997 classification system, mucocutaneous manifestations constitute 4 out of the 11 criteria that clinicians use to make a diagnosis of SLE: malar rash, discoid-lupus rash, photosensitivity, and oral or nasal mucocutaneous ulcerations. Dr. Wu recommends performing an oral exam on suspect cases, “because the oral ulcers that we see in systemic lupus tend to be painless, so oftentimes patients don’t realize they have them.”

Five other organ-specific manifestations of SLE include nonerosive arthritis, nephritis, encephalopathy, pleuritis or pericarditis, and cytopenia. The two other criteria are positive immunoserology and a positive antinuclear antibody test. “If you have any individuals present with one of these [mucocutaneous manifestations criteria], you want to think about getting a CBC to look for cytopenia or a urinalysis to look for evidence of nephritis, and potentially some additional blood studies, depending on your level of suspicion for systemic lupus,” Dr. Wu said.

Other rarer CLE manifestations include lupus pernio or chilblains, lupus panniculitis, livedo reticularis, bullous LE, urticarial vasculitis, neutrophilic dermatoses, and alopecia.

Common treatments for cutaneous manifestations associated pediatric SLE include hydroxychloroquine, low dose corticosteroids, topical steroids, methotrexate, and leflunomide. Other options for increasing severity of systemic disease include lenalidomide/thalidomide, azathioprine, calcineurin inhibitors, belimumab (Benlysta), high-dose corticosteroids, mycophenolate mofetil (CellCept), rituximab (Rituxan), and cyclophosphamide. Cutaneous manifestations of pediatric SLE can often be refractory to treatments.

In 2017, Dr. Wu and associates published a retrospective chart review of 10 adolescents who received lenalidomide for refractory CLE. One of the subjects was a 21-year-old male with a significant malar rash despite being on hydroxychloroquine, azathioprine, and prednisone 40 mg daily. “One month after being on lenalidomide he had a pretty impressive response,” Dr. Wu said. “It’s not quite clear how lenalidomide works in cutaneous lupus. Currently it’s only approved for use in myelodysplastic syndromes, multiple myeloma, as well as certain lymphomas. It’s thought to modulate different parts of the immune system, which collectively result in the cytotoxicity against tumor cells.”

Lenalidomide is supplied in capsule sizes ranging from 2.5 mg to 25 mg and is given once daily. “For a smaller child, I would think about starting 5 mg once a day,” Dr. Wu said. “For an adult-sized adolescent, you could start at 10 mg once a day and then titrate up based on response. Side effects that you need to worry about are cytopenia and GI symptoms. The venous and arterial thromboembolism risk has been seen in patients with multiple myeloma, and it is unclear if this risk is applicable to all indications.” Use of the medication requires enrollment into a safety monitoring program.
