Multicenter Canadian case series of pediatric patients less than 12 years of age with moderate-to-severe atopic dermatitis treated with dupilumab.

BACKGROUND: Dupilumab is approved for moderate-severe atopic dermatitis (AD) in patients aged ≥6 months by the US Food and Drug Administration and Health Canada; however, there are little real-world data because providers have limited practical experience with this recently approved therapy. OBJECTIVES: To describe the real-world effectiveness and safety in patients aged <12 years with moderate-severe AD currently receiving or previously having received dupilumab. METHODS: A multicenter retrospective study was conducted at six Canadian sites. Cases were divided into Group 1 ≤2 years old, Group 2 >2 to <6 years old, and Group 3 ≥6 to <12 years old. Medical history and details of dupilumab treatment were collected. The primary outcome was to measure the improvement in eczema area and severity index. Secondary outcomes examined included the children's dermatology life quality index/infant's dermatitis quality of life, peak pruritus numerical rating scale, and delay to dupilumab access for patients who were considered off-label for dupilumab due to their age. RESULTS: Sixty three pediatric patients (37 males) with moderate-to-severe AD were included; the mean age was 6.4 years old (range: 2-11) when dupilumab treatment was started. Overall, 75% (36/48) achieved EASI-75% and 71% (34/48) achieved EASI-90. EASI-75 and EASI-90 were achieved in 90% (17/19) and 73% (12/19) in patients <6 years old, and 76% (22/29) and 59% (17/29) in patients >6 years old, respectively. No serious adverse events were reported. CONCLUSIONS: Dupilumab is safe and effective for patients under the age of 12. However, even for experienced providers, access to the medication was challenging.

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.

Soft Tissue Lesions With High Vascular Density on Sonography in Pediatric Patients: Beyond Hemangiomas [Formula: see text].

Infantile hemangiomas are the most frequent vascular soft tissue lumps in the pediatric population. The clinical presentation and evolution of these lesions is characteristic, while the sonographic appearance is classic but not specific. This pictorial essay illustrates the different vascular soft tissue lumps on ultrasound that may mimic infantile hemangiomas. Awareness of these mimics is crucial to avoid misdiagnosis. Clinical and sonographic discriminators for each lesion are presented.

Approach to the Assessment and Management of Pediatric Patients With Atopic Dermatitis: A Consensus Document. Section III: Treatment Options for Pediatric Atopic Dermatitis.

Because atopic dermatitis (AD) is a chronic, relapsing disease, treatment requires the use of both active therapy to control flares and preventative maintenance therapy to promote integrity of the skin barrier. In this third of four sections, important clinical considerations for the treatment of pediatric AD are reviewed. Emerging therapies in development for pediatric AD are introduced.

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.

Utility and tolerability of the long-pulsed 1064-nm neodymium:yttrium-aluminum-garnet (LP Nd:YAG) laser for treatment of symptomatic or disfiguring vascular malformations in children and adolescents.

BACKGROUND: Vascular malformations manifest with pain, bleeding, disability, and disfigurement in a subset of children. There are scant data available on the utility and tolerability of laser surgery for symptomatic or disfiguring non-port-wine stain vascular malformations in children. OBJECTIVE: The objective of this study was to determine the utility and tolerability of the 1064-nm long-pulsed neodymium:yttrium-aluminum-garnet (LP Nd:YAG) laser for treatment of symptomatic or disfiguring vascular malformations in children. METHODS: We conducted a retrospective review of 29 pediatric patients with non-port-wine stain vascular malformations who were treated with the LP Nd:YAG laser at our institution. We report patient characteristics, treatment parameters, outcomes, and complications. RESULTS: Blinded assessment of clinical efficacy revealed good to excellent results in 66.7% of patients treated and poor to fair results in 25%. The overall rate of complications was 27%, with minor skin breakdown and blistering being the most common. LIMITATIONS: Our conclusions are limited by small sample size, pretreatment and posttreatment photographs in only a subset of patients, and lack of long-term follow-up. CONCLUSION: The LP Nd:YAG laser is a well-tolerated and effective treatment modality for a variety of non-port-wine stain vascular malformations in children.

Contact dermatitis to topical medicaments: a retrospective chart review from the Ottawa Hospital Patch Test Clinic.

BACKGROUND: Topical medicaments are a common cause of allergic contact dermatitis. This study will evaluate the prevalence of contact allergy to a wide array of topical medicaments at the Ottawa Patch Test Clinic. OBJECTIVES: The objectives of this study are to report the results of positive patch testing to topical medicaments at the Ottawa Patch Test Clinic and identify common sensitizers in topical medicaments. METHODS: Patients were tested with the standard North American Contact Dermatitis screening series of 70 allergens plus supplementary allergens when indicated. A retrospective chart review of patients positive to topical medicaments between January 1, 2000, and September 30, 2010, was undertaken. RESULTS: The average age of patients was 49.5 years. Thirty-four percent were atopic. Common sensitizers included topical antibiotics (58%), steroids (30%), anesthetics (6%), and antifungals (6%). Patch testing showed that 61% of patients tested positive to antibiotics, 21% to topical steroids, 17% tested positive to topical anesthetics, and 1% tested positive to topical antifungals. The most common reactions were to bacitracin (44%) and neomycin (29%). The most common steroid screener was tixocortol-17-pivalate (group A) (19%), and the most common local anesthetic was lidocaine (12%). CONCLUSIONS: Topical medicaments of all kinds are common causes of allergic contact dermatitis. Those that are more readily available, in over-the-counter preparations, are the most frequent culprits.
