Long-term clinical and radiological trajectories of craniocervical vasculopathy in children with PHACE syndrome.

AIM: To describe the rates of stroke and craniocervical vasculopathy progression in children with posterior fossa malformations, hemangioma, arterial anomalies, coarctation of the aorta/cardiac defects, and eye abnormalities (PHACE) syndrome. METHOD: A single-center, retrospective natural history study of children with PHACE syndrome. Clinical and sequential neuroimaging data were reviewed to study the characteristics and progression of vasculopathy and calculate the rates of arterial ischemic stroke (AIS) and transient ischemic stroke (TIA). Vasculopathy progression was defined as worsening or new vascular findings on follow-up magnetic resonance angiography. RESULTS: Thirty-four children with cerebrovascular abnormalities at the PHACE syndrome diagnosis were studied (age range = 2 to 18 years, 85% females). Median age at the initial diagnosis was 5.5 months (interquartile range = 1-52 months); median age at the last follow-up was 8 years 6 months (range = 2-18 years). Overall, 10 (29%) patients had radiological progression of their vasculopathy, with a cumulative progression-free rate of 73% (95% confidence interval [CI] = 0.57-0.89), and a cumulative TIA-free and AIS-free rate of 87% (95% CI = 0.745-0.99). Vasculopathy was continuously progressive in six patients (18%) at the last follow-up. Three patients (9%) had TIA and all had progressive vasculopathy. One patient had presumed perinatal AIS at the initial PHACE diagnosis, while no other patient experienced an AIS during the follow-up. INTERPRETATION: In children with PHACE syndrome, craniocervical vasculopathy is non-progressive and asymptomatic in the majority of cases. The risk of ischemic stroke in these children is very low. Larger and prospective studies are necessary to confirm these findings.

Stigmatization and Mental Health Impact of Chronic Pediatric Skin Disorders.

Importance: Chronic skin disorders in children frequently are visible and can cause stigmatization. However, the extent of stigmatization from chronic skin disease and association with mental health needs further study. Objective: To examine the extent of stigma, dependence on disease visibility and severity, and association with mental health and quality of life (QOL) in chronic pediatric skin disease. Design, Setting, and Participants: A cross-sectional, single-visit study was conducted at 32 pediatric dermatology centers in the US and Canada from November 14, 2018, to November 17, 2021. Participants included patients aged 8 to 17 years with chronic skin disease and 1 parent. Main Outcomes and Measures: Using the Patient-Reported Outcomes Measurement Instrumentation System (PROMIS) Stigma-Skin, the extent of stigma with child-, caregiver-, and physician-assessed disease visibility (primary outcome) and severity was compared, as well as reduced QOL (assessed by Skindex-Teen), depression, anxiety, and poor peer relationships (PROMIS child and proxy tools) (secondary outcomes). Results: The study included 1671 children (57.9% female; mean [SD] age, 13.7 [2.7] years). A total of 56.4% participants had self-reported high disease visibility and 50.5% had moderate disease severity. Stigma scores significantly differed by level of physician-assessed and child/proxy-assessed disease visibility and severity. Among children with chronic skin disorders, predominantly acne, atopic dermatitis, alopecia areata, and vitiligo, only 27.0% had T scores less than 40 (minimal or no stigma) and 43.8% had at least moderate stigma (T score ≥45) compared with children with a range of chronic diseases. Stigma scores correlated strongly with reduced QOL (Spearman ρ = 0.73), depression (ρ = 0.61), anxiety (ρ = 0.54), and poor peer relationships (ρ = -0.49). Overall, 29.4% of parents were aware of bullying of their child, which was strongly associated with stigma (Cohen d = -0.79, with children who were not bullied experiencing lower levels of stigma). Girls reported more stigma than boys (Cohen d = 0.26). Children with hyperhidrosis and hidradenitis suppurativa were most likely to have increased depression and anxiety. Conclusions and Relevance: The findings of this study suggest that physician assessment of disease severity and visibility is insufficient to evaluate the disease impact in the patient/caregiver. Identifying stigmatization, including bullying, and tracking improvement through medical and psychosocial interventions may be a key role for practitioners.

Inpatient management of epidermolysis bullosa: Consensus-based hands-on instructions for neonates and postneonates.

BACKGROUND: Epidermolysis bullosa (EB), characterized by skin fragility and blistering, often requires hospitalization. Training for inpatient management of EB is limited, with no unified recommendations available in North America. OBJECTIVE: To develop consensus-derived best practices for hands-on inpatient management of EB in both the neonatal and postneonatal period. METHODS: A modified Delphi method (expert-based input via 2 surveys and a final review) was implemented. Available guidelines from EB Clinical Research Consortium centers were analyzed to determine areas of focus and formulate statements to be voted on by EB Clinical Research Consortium members, experienced EB nurses, and select family members. Study participants evaluated statements using a Likert scale: statements with at least 70% agreement were accepted; statements with 30% or more disagreement were rejected. RESULTS: Ten areas of focus were identified. Delphi participants included 15 dermatologists, 8 nurses, and 6 nonhealth care caregivers. Consensus was established on 103/119 neonatal statements and 105/122 postneonatal statements; no statements were rejected. Most recommendations applied to both age groups. LIMITATIONS: Recommendations may require adjustment based on individual patient's clinical context. CONCLUSION: Using the Delphi method, a consensus-derived resource for hospital-based health care professionals who manage patients with EB has been developed to improve the quality of inpatient care.

Multicenter Study of Long-Term Outcomes and Quality of Life in PHACE Syndrome after Age 10.

OBJECTIVE: To characterize long-term outcomes of PHACE syndrome. STUDY DESIGN: Multicenter study with cross-sectional interviews and chart review of individuals with definite PHACE syndrome ≥10 years of age. Data from charts were collected across multiple PHACE-related topics. Data not available in charts were collected from patients directly. Likert scales were used to assess the impact of specific findings. Patient-Reported Outcomes Measurement Information System (PROMIS) scales were used to assess quality of life domains. RESULTS: A total of 104/153 (68%) individuals contacted participated in the study at a median of 14 years of age (range 10-77 years). There were infantile hemangioma (IH) residua in 94.1%. Approximately one-half had received laser treatment for residual IH, and the majority (89.5%) of participants were satisfied or very satisfied with the appearance. Neurocognitive manifestations were common including headaches/migraines (72.1%), participant-reported learning differences (45.1%), and need for individualized education plans (39.4%). Cerebrovascular arteriopathy was present in 91.3%, with progression identified in 20/68 (29.4%) of those with available follow-up imaging reports. Among these, 6/68 (8.8%) developed moyamoya vasculopathy or progressive stenoocclusion, leading to isolated circulation at or above the level of the circle of Willis. Despite the prevalence of cerebrovascular arteriopathy, the proportion of those with ischemic stroke was low (2/104; 1.9%). PROMIS global health scores were lower than population norms by at least 1 SD. CONCLUSIONS: PHACE syndrome is associated with long-term, mild to severe morbidities including IH residua, headaches, learning differences, and progressive arteriopathy. Primary and specialty follow-up care is critical for PHACE patients into adulthood.

Hidradenitis Suppurativa in Children and Adolescents: An Update on Pharmacologic Treatment Options.

Hidradenitis suppurativa (HS) is a chronic, recurrent, inflammatory skin condition that manifests as painful, deep-seated, inflamed nodules and abscesses in the axillary, groin, perianal, perineal, and inframammary regions. The associated pain, malodour, and disfigurement contribute to its profound negative impact on psychosocial spheres and overall quality of life in affected individuals. Although the symptoms of HS classically begin in the second or third decade of life, HS affects children and adolescents as well. Despite this, there are limited pediatric data on treatment, which are largely based on expert opinion, extrapolation of efficacy data in adults with HS, and safety information from medication use in other pediatric diseases. On this basis, there exist several pharmacological modalities in the treatment of children and adolescents with HS including topical therapies, systemic therapies, and biologics. The goals of this review article are to: (1) review the efficacy of different pharmacological treatment modalities in children and adolescents with HS, and (2) review the safety and monitoring considerations of the different treatment options in children and adolescents with HS.

Pediatric Dermatology in Canada: A Broad Review of Population Needs, Workforce and Training With Proposed Solutions.

INTRODUCTION: The need for pediatric dermatology services is increasing across Canada. In parallel, the complexity of treatment with novel targeted therapeutics has increased. Currently, there is no accredited and limited non-accredited fellowship training access to pediatric dermatology in Canada. HYPOTHESIS: Understanding the current state of pediatric dermatology training in Canada will provide insight into opportunities for strategic improvement. METHODS: A survey was distributed to 44 pediatric dermatology providers. In addition, a review of the burden of pediatric skin disease and education/training in Canada was performed. RESULTS: Thirty-four specialists responded to the survey (77% response rate). One third of current pediatric dermatology providers are over 50 years old and half of these (15%) plan to retire within the next 5 years. Half of respondents were dermatologists, 35% were pediatricians, and 11% were double boarded. Almost all respondents practiced in an academic setting (94%). Most had further fellowship training in pediatric dermatology (82.4%) but only 57% achieved this training in Canada, due to lack of accredited or non-accredited funded fellowship positions. CONCLUSION: There is a high and growing need for pediatric dermatology specialty care in a diverse range of settings. The current provider population and training programs are insufficient to meet current and future demands. We highlighted solutions to close this gap between supply and demand including increased double board certification in Pediatrics and Dermatology, a protected pediatric stream within existing Dermatology residency training programs and accredited fellowships in Pediatric Dermatology for both dermatologists and pediatricians.

COVID-19 associated severe mucocutaneous blistering eruptions: A case series.

Mucocutaneous eruptions are associated with numerous infectious processes and can present as erythema multiforme (EM), reactive infectious mucocutaneous eruption (RIME), Stevens Johnson syndrome (SJS), or toxic epidermal necrolysis (TEN). Limited reports have detailed the association of these eruptions with SARS-CoV-2 infection. We present a series of eight cases of severe mucocutaneous blistering eruptions associated with SARS-CoV-2 infection. A retrospective case series was performed at six tertiary medical centers from March 1, 2020 to August 1, 2022. Inclusion criteria were met with a clinical diagnosis of EM, RIME, SJS, or TEN and a positive SARS-CoV-2 test (rapid antigen or polymerase chain reaction) less than 4 weeks prior to onset of dermatologic manifestation. Data was collected at time of each patient encounter. Eight patients met criteria with six pediatric patients (<18 years of age) having a median age of 15 years and two adult patients (>18 years of age) having a median age of 36 years. Patients were found to have a clinical diagnosis of RIME in 85.7% of cases. Oral mucosal involvement was the most common clinical finding (100%), followed by ocular (50.0%), urogenital (50.0%), and skin (37.5%) involvement. Evaluation did not reveal any additional infectious triggers in four patients. Evidence of possible concurrent or previous infectious triggers were identified in four patients. This case series highlights the development of severe mucocutaneous eruptions in association with COVID-19 infection, as well as the potential contributing role of concurrent or prior infections.

Characteristics and treatment pathways in pediatric and adult hidradenitis suppurativa: An examination using real world data.

Background: Hidradenitis suppurativa (HS) is a chronic, debilitating, inflammatory disease. Contemporaneous real-world data can be used to elucidate the clinical treatment of pediatric patients and how treatment strategies compare with adult hidradenitis suppurativa patients. Objective: The objective of this study is to evaluate clinical and treatment characteristics of pediatric and adult HS patients. Methods: HS adult and pediatric patients were identified in 3 the United States administrative claims databases during the study period between 2016 to 2021. Patients were required to have 2 diagnostic codes for HS and have at least 365 days of prior observation time to the first HS diagnosis. Results: Pediatric and adult HS treatments were similar. The proportions of subjects treated with topical and oral antibiotic or oral antibiotic alone or topical medication alone or surgery alone covered 90% of the treated pediatric subjects and 91% of treated adult subjects. The remaining proportion of subjects received other treatment combinations. Limitations: The databases represent subjects with commercial or government insurance coverage and thus do not necessarily represent the broader US population. The databases do not capture information about medications obtained without insurance. Conclusions: Although subtle differences exist, this study confirms that topical and systemic therapeutic treatment of HS in adults and adolescents is very similar.

Characteristics and complications of anogenital infantile hemangiomas: A multicenter retrospective analysis.

BACKGROUND: Infantile hemangiomas (IHs) of the anogenital region remain poorly characterized. OBJECTIVE: To examine the distribution, ulceration rate, and associated congenital anomalies of anogenital IHs. METHODS: Retrospective study at 8 tertiary referral centers. RESULTS: A total of 435 infants with an IH of the anogenital region were enrolled (of which, 319 [73%] were girls). Congenital anomalies were present in 6.4% (n = 28) of infants with an anogenital IH. Segmental or partial segmental anogenital IHs ulcerated in 72% (n = 99 of 138) of infants, whereas 45% (n = 133 of 297) of focal anogenital IHs experienced ulceration (P < .001). In a multivariable logistic regression analysis, segmental or partial segmental morphology (adjusted odds ratio [aOR], 2.70; 95% CI, 1.60-4.64), mixed type (aOR, 3.44; 95% CI, 2.01-6.07), and perianal (aOR, 3.01; 95% CI, 1.53-6.12) and buttocks location (aOR, 2.08; 95% CI, 1.17-3.76) had increased odds of ulceration. Segmental or partial segmental IHs of the genitalia were confined to distinct anatomic territories and were predominantly distributed unilaterally, with a linear demarcation at the perineal raphe. LIMITATIONS: Possible selection bias, given recruitment at tertiary referral centers. CONCLUSION: This study improves our understanding of high-risk features of anogenital IHs and demonstrates that genital segmental or partial segmental IHs develop within distinct anatomic territories.

Methotrexate for inflammatory skin disease in pediatric patients: Consensus treatment guidelines.

Methotrexate (MTX) is a readily accessible drug, first used in 1948 and employed for a wide variety of indications since then. However, despite widespread off-label use, FDA labeling does not include approved indications for the use of MTX for many inflammatory skin diseases in pediatric patients, including morphea, psoriasis, atopic dermatitis, and alopecia areata, among others. Without published treatment guidelines, some clinicians may be hesitant to use MTX off-label, or uncomfortable prescribing MTX in this population. To address this unmet need, an expert consensus committee was convened to develop evidence- and consensus-based guidelines for use of MTX to treat pediatric inflammatory skin disease. Clinicians with experience and expertise in clinical research, drug development, and treating inflammatory skin disease in pediatric patients with MTX were recruited. Five committees were created based on major topic areas: (1) indications and contraindications, (2) dosing, (3) interactions with immunizations and medications, (4) adverse effects (potential for and management of), and (5) monitoring needs. Pertinent questions were generated and addressed by the relevant committee. The entire group participated in a modified Delphi process to establish agreement on recommendations for each question. The committee developed 46 evidence- and consensus-based recommendations, each with >70% agreement among members, across all five topics. These are presented in tables and text, along with a discussion of supporting literature, and level of evidence. These evidence- and consensus-based recommendations will support safe and effective use of MTX for the underserved population of pediatric patients who may benefit from this valuable, time-honored medication.

The role of nutrition, food allergies, and gut dysbiosis in immune-mediated inflammatory skin disease: a narrative review.

PURPOSE OF REVIEW: This review focuses on the emerging roles of nutrition, food allergies, and gut dysbiosis, and their influence on pediatric skin conditions such as psoriasis, hidradenitis suppurativa, and alopecia areata. As the prevalence of these conditions increases, understanding the underlying mechanisms and potential therapeutic targets is crucial for clinical practice and research. RECENT FINDINGS: The review covers 32 recent articles that highlight the significance of the gut microbiome, nutrition, and gut dysbiosis in the pathogenesis and progression of inflammatory and immune-related pediatric skin conditions. The data suggest that food allergies and gut dysbiosis play a crucial role in disease pathogenesis. SUMMARY: This review emphasizes the need for larger-scale studies to determine the effectiveness of dietary changes in preventing or treating inflammatory and immune-related skin conditions. Clinicians must maintain a balanced approach when implementing dietary changes in children with skin diseases like atopic dermatitis to avoid potential nutritional deficiencies and growth impairments. Further research into the complex interplay between environmental and genetic factors is warranted to develop tailored therapeutic strategies for these skin conditions in children.

Hidradenitis Suppurativa in Pediatric Patients.

Hidradenitis suppurativa is a chronic inflammatory skin disorder primarily affecting apocrine gland-bearing areas, including the axillae, groin, and buttocks. It is reported in up to 2% of Western populations and with increasing incidence in children and adults. Nearly one-third of hidradenitis suppurativa cases occur in pediatric patients and nearly half of patients endorse initial symptoms in childhood. To date, there are few clinical studies and guidelines for pediatric hidradenitis suppurativa. Here, we review the epidemiology, clinical presentation, comorbidities, and management of pediatric hidradenitis suppurativa. We discuss barriers contributing to delays in diagnosis and the significant physical and emotional impact of the disease on children and adolescents.

Consensus guidelines for diagnosis and management of anemia in epidermolysis bullosa.

BACKGROUND: Anemia is a common complication of severe forms of epidermolysis bullosa (EB). To date, there are no guidelines outlining best clinical practices to manage anemia in the EB population. The objective of this manuscript is to present the first consensus guidelines for the diagnosis and management of anemia in EB. RESULTS: Due to the lack of high-quality evidence, a consensus methodology was followed. An initial survey exploring patient preferences, concerns and symptoms related to anemia was sent to EB patients and their family members. A second survey was distributed to EB experts and focused on screening, diagnosis, monitoring and management of anemia in the different types of EB. Information from these surveys was collated and used by the panel to generate 26 consensus statements. Consensus statements were sent to healthcare providers that care for EB patients through EB-Clinet. Statements that received more than 70% approval (completely agree/agree) were adopted. CONCLUSIONS: The end result was a series of 6 recommendations which include 20 statements that will help guide management of anemia in EB patients. In patients with moderate to severe forms of EB, the minimum desirable level of Hb is 100 g/L. Treatment should be individualized. Dietary measures should be offered as part of management of anemia in all EB patients, oral iron supplementation should be used for mild anemia; while iron infusion is reserved for moderate to severe anemia, if Hb levels of > 80-100 g/L (8-10 g/dL) and symptomatic; and transfusion should be administered if Hb is < 80 g/L (8 g/dL) in adults and < 60 g/L (6 g/dL) in children.

Early diagnosis of ichthyosis, leukocyte vacuoles, alopecia, and sclerosing cholangitis syndrome: A case report.

Congenital ichthyosis is a genodermatosis characterized by abnormal epidermal differentiation. The neonatal period is critical for patients with ichthyosis because of the risk for significant comorbidities and associated mortality, with most complications resulting from impaired barrier function. Early recognition can significantly alter the clinical course of this rare disease. Here we present a neonate with ichthyosis, leukocyte vacuoles, alopecia, and sclerosing cholangitis syndrome (ILVASC), a rare inherited disease, to highlight how an interdisciplinary approach led to prompt assessment, confirmation of a genetic diagnosis and management of potential complications.

Incidence and clinical factors associated with ulceration in infantile hemangiomas.

BACKGROUND: Ulceration is an important complication in infantile hemangiomas (IHs). Prior to the use of ß-blockers, the estimated incidence of this complication in a referral population was between 15% and 30%. The incidence and factors associated with ulceration have not been systematically studied since the emergence of ß-blocker therapy. OBJECTIVE: Examine the incidence and clinical predictors for ulceration in IHs. METHODS: Retrospective study at tertiary referral centers. RESULTS: Compared with a previous large pre-propranolol cohort study, ulceration occurred at a significantly lower incidence of 11.4%. Clinical factors associated with ulceration included partial segmental morphology, location in the diaper area, and size greater than 5 cm. Higher risk of ulceration in Black patients was observed, suggesting barriers to care including delayed diagnosis and referral to specialty care. LIMITATIONS: Retrospective design at tertiary referral centers. CONCLUSION: Compared with reports before the use of ß-blockers became widespread, the incidence of ulceration in IHs has decreased. However, it continues to be a relatively frequent complication of IH.

Transition of care in patients with epidermolysis bullosa: A survey study.

There are little published data on the transition of care in EB. We conducted a survey study recruiting EB patients from the Dystrophic EB Research Association (debra) website and centers caring for high numbers of EB patients in the United States and internationally from Sept 17, 2019 to Nov 3, 2021. The majority of participants had not discussed the transition of care with their healthcare providers, nor the healthcare needs to be required as an adult. Ongoing pediatric subspecialty care was reported by 12% of adults, most commonly in pediatric dermatology. Identified barriers to transition included the perceived lack of adult providers' knowledge about EB patient healthcare needs. The results suggest the need for transition guidelines, early discussions with families about transition, and practical information for the adult providers accepting care.

Two congenital cases of pigmented epithelioid melanocytoma with unique clinical and genetic features.

Pigmented epithelioid melanocytomas (PEM) are intermediate-grade melanocytic lesions with frequent lymph node involvement and rare metastases that tend to follow an indolent course with a favorable outcome. We report two unique cases of congenital PEM with PRKCA fusion transcripts: a multifocal PEM with an aggressive incompletely resectable scalp tumor and a solitary palmar PEM with newly reported ITGB5-PRKCA fusion. Through these case reports and a summary of previously reported cases, we outline the spectrum of disease of PEM and highlight the key clinical and histopathologic features associated with PEM with PRKCA fusion transcripts. We also discuss the treatment options and suggest that surgical excision without further adjuvant systemic treatment is reasonable first-line therapy given the favorable prognosis.
