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.

Chilblain-Like Lesions (CLL) Associated With COVID-19 ("COVID Toes"): A Systematic Review.

Reports of chilblain-like lesions (CLL) coinciding with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been described in the literature, but this phenomenon has not been critically summarized. The aim of this paper is to summarize reports of CLL coinciding with SARS-CoV-2 infection to clarify the prevalence, clinical relevance, and prognostic value of these lesions. A literature search was conducted using the Embase, Pubmed, and Scopus databases from December 2019 to June 16, 2020 using the search terms ("COVID-19" OR "coronavirus" OR "2019-nCoV" OR "SARS-CoV-2") AND ("chilblain-like" OR "COVID toes" OR "acral"). Papers that described skin changes in patients with suspected or confirmed COVID-19 were included. A total of 31 papers were summarized, representing 813 cases of CLL. Available data suggests an equal gender distribution, mean age of 21 years, and median age of 14 years. Mild extracutaneous symptoms were reported in 53% of cases and 47% were asymptomatic. CLL occurred an average of 16 days after extracutaneous symptoms. Patients with CLL were positive for SARS-CoV-2 in 15% of cases. Lesions were mainly described as asymptomatic and/or pruritic erythematous to violaceous acral macules and plaques. Partial or complete resolution occurred in 85% of cases in a mean of 13 days. The most common histologic findings were perivascular and perieccrine superficial and deep lymphocytic infiltrates. Although a causal relationship between CLL and SARS-CoV-2 has not been confirmed, the temporal association and 15% positive SARS-CoV-2 rate in affected individuals should not be ignored.

Management of pediatric plaque psoriasis using biologics.

BACKGROUND: Psoriasis is a chronic inflammatory disease with clinical manifestations of the skin that affect adults and children. In adults, biologics have revolutionized the treatment of moderate to severe plaque psoriasis where clear or almost clear is a tangible goal. Research on biologics has recently been extended to children. The introduction of these new therapeutic options has outpaced the limited guidelines in this population. OBJECTIVE: To provide a review of current data on biologics, with a proposal for a clinically relevant treatment algorithm on the management of moderate to severe plaque psoriasis in the pediatric population. METHODS: A Canadian panel with expertise in psoriasis, pediatric dermatology, and experience with consensus recommendation processes was selected to review the current landscape of pediatric psoriasis and clinical data on biologics plus identify special considerations for baseline workup and monitoring. Recommendations were reviewed and edited by each expert in an iterative process. CONCLUSION: A treatment algorithm for moderate to severe plaque psoriasis in pediatric patients is presented, incorporating approved biologics. Guidance on baseline screening and ongoing monitoring is also provided. Ultimately, treatment choice depends on the patient and his or her caregiver, with consideration of comorbidities, impact on quality of life, and relevant safety aspects.

Approach to the Assessment and Management of Pediatric Patients With Atopic Dermatitis: A Consensus Document. Section IV: Consensus Statements on the Assessment and Management of Pediatric Atopic Dermatitis.

This document is intended to provide practical guidance to physicians treating pediatric atopic dermatitis (AD), especially dermatologists, pediatricians, allergists, and other health-care professionals. The recommendations contained here were formalized based on a consensus of 12 Canadian pediatric dermatologists, dermatologists, pediatricians, and pediatric allergists with extensive experience managing AD in the pediatric population. A modified Delphi process was adopted with iterative voting on a 5-point Likert scale, with a prespecified agreement cutoff of 75%. Topic areas addressed in the 17 consensus statements reflect areas of practical management, including counselling, assessment, comorbidity management, and therapy.

Approach to the Assessment and Management of Pediatric Patients With Atopic Dermatitis: A Consensus Document. Section I: Overview of Pediatric Atopic Dermatitis.

Pediatric atopic dermatitis (AD) is one of the most common dermatoses encountered by health-care providers treating children. Diagnosis of AD is clinical, with no universally accepted biomarkers or assessment tools. Patient-reported outcomes and subjective assessments of quality of life in both the patient and family are important considerations when treating pediatric AD. Here, we provide an overview of pediatric AD epidemiology, its clinical presentation, burden, diagnosis, and assessment, with a focus on implications for patient counseling in order to optimize care.

Clinical Insights About Topical Treatment of Mild-to-Moderate Pediatric and Adult Atopic Dermatitis.

Atopic dermatitis (AD) is a chronic inflammatory skin condition, also referred to as atopic eczema, that is identified by itching and recurrent eczematous lesions. It often starts in infancy where it affects up to 20% of children but is also highly prevalent in adults. AD inflicts a significant psychosocial burden on patients and their families and increases the risk of other immune-mediated inflammatory conditions, such as asthma and allergic rhinitis, food allergy, and mental health disorders. It is a lifelong condition associated with epidermal barrier dysfunction and altered immune function. Through the use of emollients and anti-inflammatory agents, current prevention and treatment therapies attempt to restore epidermal barrier function. Acute flares are treated with topical corticosteroids. Topical calcineurin inhibitors (TCIs) and topical corticosteroids (TCSs) are used for proactive treatment to prevent remission. There remains a need and opportunity to improve AD care through future research directed toward an improved understanding of the heterogeneity of the disease and its subtypes, the role of autoimmunity in its pathogenesis, the mechanisms behind disease-associated itch and response to specific allergens, and the comparative effectiveness and safety of therapies.

Knowing Their Place: The Blue Hill Observatory and the Value of Local Knowledge in an Era of Synoptic Weather Forecasting, 1884-1894.

Argument The history of meteorology has focused a great deal on the "scaling up" of knowledge infrastructures through the development of national and global observation networks. This article argues that such efforts to scale up were paralleled by efforts to define a place for local knowledge. By examining efforts of the Blue Hill Meteorological Observatory, near Boston, Massachusetts, to issue local weather forecasts that competed with the centralized forecasts of the U.S. Signal Service, this article finds that Blue Hill, as a user of the Signal Service's observation network, developed a new understanding of local knowledge by combining local observations of the weather with the synoptic maps afforded by the nationwide telegraph network of the U.S. Signal Service. Blue Hill used these forecasts not only as a service, but also as evidence of the superiority of its model of local forecasting over the Signal Service's model, and in the process opened up larger questions about the value of a weather forecast and the value of different kinds of knowledge in meteorology.

Development of a Clinical Pathway for Atopic Dermatitis Patients: A Case-Based Approach.

BACKGROUND: Atopic dermatitis (AD) is a common chronic skin condition, associated with significant patient morbidity. There are a myriad of excellent evidenced based guidelines to guide clinicians by an extensive review of all the available treatments. However, while well written and complete these papers may not always allow easy transition to clinical application. OBJECTIVE: The purpose of this paper was to develop a practical case-based approach for the treatment and maintenance of AD, enabling translation of guidelines into clinical care. METHODS: After literature searches, selected AD trials and recent existing guidelines were reviewed. Using a nominal group process for consensus, an expert panel of Canadian dermatologists determined the case features and corresponding treatments. RESULTS: A patient focused clinical pathway with 7 cases was developed. For each case scenario, treatment for mild, moderate, and severe disease was recommended. CONCLUSION: A practical case-based clinical pathway was developed for easy clinical application and optimal patient care. J Drugs Dermatol. 2016;15(12):1485-1494.

5% 5-Fluorouracil cream for treatment of verruca vulgaris in children.

Warts are a common pediatric skin disease. Most treatments show only modest benefit, and some are poorly tolerated because of pain. 5-fluorouracil interferes with deoxyribonucleic acid and ribonucleic acid synthesis, and is used to treat genital warts in adults. Efficacy, safety, and tolerability of topical 5% 5-fluorouracil for treatment of common warts were examined in an open-label pilot study with pediatric patients. Thirty-nine children who have at least two hand warts applied 5% 5-fluorouracil cream (Efudex, Valeant Pharmaceuticals International) once or twice daily, under occlusion for 6 weeks. Assessment of treatment response and side effects was performed at baseline, treatment completion, and 3- and 6-month follow-ups. Hematology measures, liver function tests, and medication blood levels were reassessed at treatment completion. Eighty-eight percent of treated warts improved after 6 weeks of treatment, and 41% of subjects had complete resolution of at least one wart. Treatment response did not differ between once or twice daily applications. Tolerability and patient satisfaction were excellent. No subject had clinically significant blood levels of 5-fluorouracil. At 6 month follow-up, 87% of complete responders had no wart recurrence. Topical 5% 5-fluorouracil is a safe, effective, and well-tolerated treatment for warts in children.

Identifying potential regulators of infantile hemangioma progression through large-scale expression analysis: a possible role for the immune system and indoleamine 2,3 dioxygenase (IDO) during involution.

Hemangiomas are benign endothelial tumors. Often referred to as hemangiomas of infancy (HOI), these tumors are the most common tumor of infancy. Most of these lesions proliferate rapidly in the first months of life, and subsequently slowly involute during early childhood without significant complications. However, they often develop on the head or neck, and may pose a significant cosmetic concern for families. In addition, a fraction of these tumors can grow explosively and ulcerate, bleed, or obstruct vision or airway structures. Current treatments for these tumors are associated with significant side effects, and our knowledge of the biology of hemangiomas is limited. The natural evolution of these lesions creates a unique opportunity to study the changes in gene expression that occur as the endothelium of these tumors proliferates and then subsequently regresses. Such information may also increase our understanding of the basic principals of angiogenesis in normal and abnormal tissue. We have performed large-scale genomic analysis of hemangioma gene expression using DNA microarrays. We recently identified insulin-like growth factor 2 as a potentially important regulator of hemangioma growth using this approach. However, little is known about the mechanisms involved in hemangioma involution. Here we explore the idea that hemangioma involution might be an immune-mediated process and present data to support this concept. We also demonstrate that proliferating hemangiomas express indoleamine 2,3 dioxygenase (IDO) and discuss a possible mechanism that accounts for the often slow regression of these lesions.
