    Abstract Psoriasis represents a potentially life-altering disease that can profoundly impact physical, emotional and social functioning, and overall quality of life. The majority of cases are mild and managed adequately with topical medications. A minor subset of children present with severe, rapidly evolving disease that requires systemic therapy. The choice of treatment in children, as in adults, is determined by disease acuity, morphology, distribution, severity and the presence of comorbidities such as psoriatic arthropathy. Practical considerations such as ease of use, patient acceptability, accessibility, risk to benefit ratio, cost and individual perceptions of disease and quality of life are factored into treatment decisions. Part I of this 2-part series will focus on topical agents, their varying degrees of effectiveness, potential side-effects and applications in clinical practice.

    Abstract The choice of treatment for psoriasis in children, as in adults, is determined by disease acuity, morphology, distribution, severity, and the presence of comorbidities, such as psoriatic arthropathy. Fortunately, most patients present with mild disease that responds adequately to topical medications. A minor subset of children will present with severe, rapidly evolving disease that requires more aggressive interventions. Advanced medical treatment with systemic and phototherapy is challenging and primarily anecdotal, as these modalities are neither well-studied nor approved for use in children. Part II of this 2-part series features an overview of systemic and light therapies including their varying degrees of effectiveness, potential side-effects and applications in clinical practice.

    Abstract The exact role of biologics in the treatment of pediatric psoriasis remains undefined but is evolving. Biologics are an attractive option for use in children in part because they offer more convenient dosing regimens and less frequent laboratory monitoring than traditional systemic agents. Further, because their action is targeted, they theoretically lack many of the potential end-organ toxicities of traditional agents. However, compared to adult psoriasis populations, there is a relative lack of long-term safety data specific to the pediatric psoriasis population. Thus, the clear advantages of using biologic agents must be balanced with a measure of caution. This article will provide a summary of the cumulative pediatric safety and efficacy data for the anti-tumor necrosis factor-alpha (TNF-α) agents and interleukin (IL)-12 and IL-23 (IL12/23) pathway inhibitor and suggestions for a rational clinical approach to their use in children with psoriasis.

    Abstract To date, the US FDA has approved three tumor necrosis factor (TNF)-a inhibitors for use in dermatology. Etanercept (Enbrel, Amgen-Wyeth), a fully human fusion protein of TNF receptor II bound to the Fc component of human IgG1, is approved for use in psoriasis (2004) and psoriatic arthritis (2002). Infliximab (Remicade, Centocor) is a chimeric monoclonal antibody that is approved for use in psoriasis (2006) and psoriatic arthritis (2005), and adalimumab (Humira, Abbott Laboratories), a fully human monoclonal antibody, is approved for use in psoriatic arthritis (2005). While data regarding the efficacy and safety of these therapies is abundant, it proves nearly impossible to objectively compare and contrast agents as there are no head-to-head trials. Clinical experience and post-marketing reporting has allowed dermatologists to identify the relative strengths and limitations of each agent. The well-founded enthusiasm for these agents, because of their excellent initial efficacy and safety profile, is reasonably tempered by concerns about declining efficacy over time, the risk of infection, lymphoma and demyelinating disorders, and cost. The distinct and targeted mechanism of action of the TNF inhibitors allows dermatologists to customize therapy to match the individual needs and characteristics of patients who are candidates for systemic or phototherapy.

    Abstract Subcutaneous panniculitis-like T-cell lymphoma is a cutaneous lymphoma characterized by CD8+ T-cell infiltrate in the subcutis that is rare in children. Acute lymphoblastic lymphoma is the most common pediatric malignancy and often presents with fevers and pancytopenia. Herein, we report 2 pediatric patients presenting with subcutaneous panniculitis-like T-cell lymphoma and B-cell acute lymphoblastic lymphoma, distinct hematologic malignancies arising from different lymphoid lineages, with no identifiable germline cancer predisposition.

    Abstract Cerebrotendinous xanthomatosis (CTX) is a rare, autosomal recessive, inborn error of bile acid metabolism characterized by diarrhea in infancy, juvenile cataracts in childhood, tendon xanthomas developing in the second to third decades of life, and progressive neurologic dysfunction in adulthood. The condition is caused by mutations in the CYP27A1 gene that result in decreased production of chenodeoxycholic acid (CDCA) and elevated levels of cholestanol and bile alcohols. We present a 36-year-old male of Han ethnicity who developed xanthomas of his Achilles tendons and suffered neurocognitive declines and gait deterioration in his second decade. The diagnosis of CTX was confirmed by marked elevation of the serum cholestanol level. Sequencing of CYP27A1 showed a paternally inherited splice mutation, c.446 + 1G>T, and a maternally inherited nonsense mutation, c.808C>T, predicting p.(Arg270*). Despite the advanced disease in this patient, treatment with CDCA reduced the xanthoma size and improved his cognition and strength, and the patient made significant gains in his ambulation and coordination. We report this case to illustrate the potential benefits of therapy in patients with CTX who have advanced disease at the time of diagnosis.

    Abstract Importance: Few studies have compared the use of methotrexate and biologics, the most commonly used systemic medications for treatment of moderate to severe psoriasis in children.
    Objective: To assess the real-world, 6-month reduction in psoriasis severity and long-term drug survival (rate and duration of adherence to a specific drug) of methotrexate vs biologics in plaque psoriasis in children.
    Design, setting, and participants: A retrospective medical records review was conducted at 20 European and North American centers. Treatment response was based on site-reported Psoriasis Area and Severity Index (PASI) and/or Physician Global Assessment (PGA) scores at baseline and within the first 6 months of treatment. Participants included all 234 consecutively seen children with moderate to severe psoriasis who received at least 3 months of methotrexate or biologics from December 1, 1990, to September 16, 2014, with sufficient data for analysis. Data analysis was performed from December 14, 2015, to September 1, 2016.
    Main outcomes and measures: PASI, with a range from 0 to 72 (highest score indicating severe psoriasis), and/or PGA, with a scale of 0 (clear), 1 (minimal), 2 (mild), 3 (moderate), 4 (severe), and 5 (very severe).
    Results: Of 234 pediatric patients (103 boys [44.0%]; 131 girls [56.0%]) treated with methotrexate and/or biologics, 163 patients (69.7%) exclusively received methotrexate, 47 patients (20.1%) exclusively received biologics, and 24 children (10.2%) received methotrexate and biologics sequentially. Of the latter cohort, 23 children were treated initially with methotrexate. Mean (SD) age at initiation was 11.6 (3.7) years for methotrexate and 13.3 (2.9) years for biologics (73.2% for etanercept) (P = .002). Among patients evaluated by a scoring method at 6-month follow-up, 75% or greater improvement in PASI (PASI75) was achieved in 12 of 30 patients (40.0%) receiving methotrexate and 20 of 28 patients (71.4%) receiving biologics, and PGA was clear/almost clear (PGA 0/1) in 41 of 115 patients (35.6%) receiving methotrexate and 18 of 37 patients (48.6%) receiving biologics. Achieving PASI75 and/or PGA 0/1 between baseline and 6 months was more likely with biologics than methotrexate (PASI75: odds ratio [OR], 4.56; 95% CI, 2.02-10.27; P < .001; and PGA 0/1: OR, 2.00; 95% CI, 0.98-4.00; P = .06). Decreased mean PASI and PGA scores were associated with biologics more than with methotrexate (PASI effect, -3.13; 95% CI, -4.33 to -1.94; P < .001; and PGA effect, -0.31; 95% CI, -0.56 to -0.06; P = .02). After 1, 3, and 5 years of use, overall drug survival rates for methotrexate were 77.5%, 50.3%, and 35.9%, and for biologics, the rates were 83.4%, 64.3%, and 57.1%, respectively. Biologics were associated with a better confounder-corrected drug survival than methotrexate (hazard ratio [HR], 2.23; 95% CI, 1.21-4.10; P = .01). Discontinuation owing to lack of response was comparable (HR, 1.64; 95% CI, 0.80-3.36; P = .18).
    Conclusions and relevance: Methotrexate and biologics appear to be associated with improvement in pediatric psoriasis, although biologics seem to be associated with greater reduction in psoriasis severity scores and higher drug survival rates than methotrexate in the real-world setting. Additional studies directly comparing these medications should be performed for confirmation.

    Abstract Background: Pediatric melanoma is rare and diagnostically challenging.
    Objective: To characterize clinical and histopathologic features of fatal pediatric melanomas.
    Methods: Multicenter retrospective study of fatal melanoma cases in patients younger than 20 years diagnosed between 1994 and 2017.
    Results: Of 38 cases of fatal pediatric melanoma identified, 57% presented in white patients and 19% in Hispanic patients. The average age at diagnosis was 12.7 years (range, 0.0-19.9 y), and the average age at death was 15.6 years (range, 1.2-26.2 y). Among cases with known identifiable subtypes, 50% were nodular (8/16), 31% were superficial spreading (5/16), and 19% were spitzoid melanoma (3/16). One fourth (10/38) of melanomas arose in association with congenital melanocytic nevi.
    Limitations: Retrospective nature, cohort size, and potential referral bias.
    Conclusions: Pediatric melanoma can be fatal in diverse clinical presentations, including a striking prevalence of Hispanic patients compared to adult disease, and with a range of clinical subtypes, although no fatal cases of spitzoid melanoma were diagnosed during childhood.

    Abstract Background: Evidence from adult psoriasis studies implicates an imbalance between regulatory and effector T cells, particularly T
    Objective: We sought to functionally characterize the inflammatory cell profiles of psoriatic plaques from pediatric patients and compare them with healthy, age-matched controls and adult psoriasis patients.
    Methods: Skin samples from pediatric psoriasis patients and healthy controls were analyzed by multiparameter flow cytometry to determine the dominant immune cell subsets present and cytokines produced.
    Results: Lesional tissue from pediatric psoriasis patients had significantly increased interleukin (IL) 22 derived from CD4
    Limitations: This is a pilot study, thus the sample size is small.
    Conclusion: Significant differences in IL-17 and IL-22 expression were observed in the pediatric psoriasis patients compared with pediatric healthy controls and adult psoriasis patients. IL-22 might be relevant in the pathogenesis of pediatric psoriasis and represents a potential treatment target unique to pediatric psoriasis.
