RESUMEN
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic malignancy with historically poor outcomes and no worldwide consensus treatment approach. Unique among most hematologic malignancies for its frequent cutaneous involvement, BPDCN can also invade other extramedullary compartments, including the central nervous system. Generally affecting older adults, many patients are unfit to receive intensive chemotherapy, and although hematopoietic stem cell transplantation is preferred for younger, fit individuals, not all are eligible. One recent therapeutic breakthrough is that all BPDCNs express CD123 (IL3Rα) and that this accessible surface marker can be pharmacologically targeted. The first-in-class agent for BPDCN, tagraxofusp, which targets CD123, was approved in December 2018 in the United States for patients with BPDCN aged ≥2 years. Despite favorable response rates in the frontline setting, many patients still relapse in the setting of monotherapy, and outcomes in patients with relapsed/refractory BPDCN remain dismal. Therefore, novel approaches targeting both CD123 and other targets are actively being investigated. To begin to formally address the state of the field, we formed a new collaborative initiative, the North American BPDCN Consortium (NABC). This group of experts, which includes a multidisciplinary panel of hematologists/oncologists, hematopoietic stem cell transplant physicians, pathologists, dermatologists, and pediatric oncologists, was tasked with defining the current standard of care in the field and identifying the most important research questions and future directions in BPDCN. The position findings of the NABC's inaugural meetings are presented herein.

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.

RESUMEN
BACKGROUND: Kaposiform hemangioendothelioma (KHE) is a locally aggressive and potentially lethal vascular tumor of infancy. Current consensus recommendations include the use of vincristine and/or systemic steroids as first-line treatment. Mammalian target of rapamycin (mTOR) inhibitors represent a promising therapy for patients with KHE. The goal of our study is to critically assess the existing literature on outcomes of patients with KHE treated with mTOR inhibitors. METHODS: We conducted a literature search from 1 January 2000, to 30 April 2022. Articles reporting outcomes of patients treated with mTOR inhibitors for KHE were included. Descriptive statistics were used to describe and summarize the outcomes of the treatment. RESULTS: We included 327 patients with a mean age at diagnosis of 9.1 months (SD ± 9). Patients were treated with an mTOR inhibitor for a mean of 15.2 months (SD ± 4.1). A total of 315 (96.3%) patients had positive outcomes including improvement of the tumor size, symptoms and/or laboratory parameters in 227 (85%) and complete remission in 38 (12%). Seven (2%) patients did not respond to treatment and seven (2%) died of sepsis (4), Kasabach-Merritt phenomenon complications (1), cardiac and liver failure due to ductus arteriosus (1), or metastatic disease (1). CONCLUSION: This systematic review supports the efficacy and safety of mTOR inhibitors for KHE. Their use resulted in positive outcomes in terms of decreased symptoms, reduction in tumor size and improvement in biochemical parameters with a mortality rate of 2%. According to these findings, we suggest revised consensus treatment guidelines for KHE with mTOR inhibitors potentially considered first-line therapy.

BACKGROUND/OBJECTIVES: The primary objective was to assess pain catastrophizing and functional disability in pediatric patients with epidermolysis bullosa (EB) and their parents/guardians. Secondary objectives included examining relationships between pain catastrophizing, functional disability, and correlations with other factors (e.g., age, disease severity, and percent of body surface area (BSA) involved). METHODS: Patients with EB ages 8-16 and their parents/guardians who were English or Spanish speaking completed a one-time online survey. Parent measures included: demographics questionnaire, Pain Catastrophizing Scale-Parent (PCS), and Parent Functional Disability Inventory (FDI). Child measures included: PCS child and child FDI. Higher scores on both scales indicate higher levels of catastrophizing and functional disability. RESULTS: Of 31 children, the mean age was 11.47 years and the majority (70.97%) had dystrophic EB. Mean scores were: 35.84 = PCS parent; 34.58 = PCS child; 30.87 = parent FDI; 29.77 = child FDI. Total scores for PCS parent, parent FDI, and child FDI increased significantly with disease severity and percentage of involved BSA (p < .01 for all). Total scores for PCS child increased significantly with percent of EB skin involvement (p = .04) but not disease severity. Older children reported more functional disability than their parents and younger children (p = .02). CONCLUSIONS: Our results demonstrate significant positive correlations between negative thoughts related to pain and the experience of functional difficulties in patients with EB and their caregivers. Psychological, psychiatric, and/or behavioral interventions to help managing chronic pain may be effective for patients with EB.

BACKGROUND: Bleach bathing is frequently recommended to treat atopic dermatitis (AD), but its efficacy and safety are uncertain. OBJECTIVE: To systematically synthesize randomized controlled trials (RCTs) addressing bleach baths for AD. METHODS: We searched MEDLINE, EMBASE, CENTRAL, and GREAT from inception to December 29, 2021, for RCTs assigning patients with AD to bleach vs no bleach baths. Paired reviewers independently and in duplicate screened records, extracted data, and assessed risk of bias (Cochrane version 2) and GRADE quality of evidence. We obtained unpublished data, harmonized individual patient data and did Frequentist and Bayesian random-effects meta-analyses. RESULTS: There were 10 RCTs that enrolled 307 participants (median of mean age 7.2 years, Eczema Area Severity Index baseline mean of means 27.57 [median SD, 10.74]) for a median of 6 weeks (range, 4-10). We confirmed that other trials registered globally were terminated. Bleach baths probably improve AD severity (22% vs 32% improved Eczema Area Severity Index by 50% [ratio of means 0.78, 95% credible interval 0.59-0.99]; moderate certainty) and may slightly reduce skin Staphylococcal aureus colonization (risk ratio, 0.89 [95% confidence interval, 0.73-1.09]; low certainty). Adverse events, mostly dry skin and irritation, along with itch, patient-reported disease severity, sleep quality, quality of life, and risk of AD flares were not clearly different between groups and of low to very low certainty. CONCLUSION: In patients with moderate-to-severe AD, bleach baths probably improve clinician-reported severity by a relative 22%. One in 10 will likely improve severity by 50%. Changes in other patient-important outcomes are uncertain. These findings support optimal eczema care and the need for additional large clinical trials.

The prognosis of IgA vasculitis (also known as Henoch-Schönlein purpura) is determined by renal or other organ involvement. We conducted a retrospective study to identify the initial features of 106 children with IgA vasculitis and their association with unfavorable outcomes. Location of purpura above the waist and an altered urinalysis at diagnosis predicted a more aggressive course of disease.

OBJECTIVE: To estimate Covid-19 and pre-pandemic low respiratory infection (LRI) mortality in children and adolescents in Mexico. MATERIALS AND METHODS: We estimated the percentage of total mortality attributable to Covid-19 (95% confidence intervals; 95%CI) and made the corresponding estimates for pre-pandemic LRI mortality. RESULTS: In 2019, LRIs represented 8.6% (95%CI 8.3, 8.9) of deaths in children aged 0-9 years, and 2.0% (95%CI 1.8, 2.3) in those aged 10-19 years. In 2020, the corresponding estimates for Covid-19 were 4.4% (95%CI 4.1, 4.6) and 3.7% (95%CI 3.4, 4.1). CONCLUSIONS: Relative to LRI, Covid-19 may be exerting a considerable mortality burden, particularly in older children and adolescents.

BACKGROUND: The distribution of pediatric-onset morphea and site-based likelihood for extracutaneous complications has not been well characterized. OBJECTIVE: To characterize the lesional distribution of pediatric-onset morphea and to determine the sites with the highest association of extracutaneous manifestations. METHODS: A retrospective cross-sectional study was performed. Using clinical photographs, morphea lesions were mapped onto body diagrams using customized software. RESULTS: A total of 823 patients with 2522 lesions were included. Lesions were more frequent on the superior (vs inferior) anterior aspect of the head and extensor (vs flexor) extremities. Linear morphea lesions were more likely on the head and neck, whereas plaque and generalized morphea lesions were more likely on the trunk. Musculoskeletal complications were more likely with lesions on the extensor (vs flexor) extremity (odds ratio [OR], 2.0; 95% confidence interval [CI], 1.2-3.4), whereas neurologic manifestations were more likely with lesions on the anterior (vs posterior) (OR, 2.8; 95% CI, 1.7-4.6) and superior (vs inferior) aspect of the head (OR, 2.3; 95% CI, 1.6-3.4). LIMITATIONS: Retrospective nature and the inclusion of only patients with clinical photographs. CONCLUSION: The distribution of pediatric-onset morphea is not random and varies with body site and within individual body sites. The risk stratification of extracutaneous manifestations by body site may inform decisions about screening for extracutaneous manifestations, although prospective studies are needed.

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive malignancy of the skin and hematopoietic system. There are few pediatric cases reported in the literature. Management of primary cutaneous BPDCN is challenging because, despite an apparently indolent clinical presentation, rapid dissemination with high mortality can occur. We describe a child with isolated cutaneous involvement who had a good response to chemotherapy as first-line treatment of BPDCN.

BACKGROUND AND OBJECTIVES: Skin diseases are a common reason for emergency department (ED) consultations; however, few studies have focused on pediatric patients. Diagnostic consistency between ED physicians and dermatologists varies from 43% to 58%, meaning many patients seeking emergency care may receive incorrect diagnoses and treatments. We aimed to determine the diagnostic concordance between ED physicians and pediatric dermatologists. METHODS: We conducted a prospective study including all pediatric patients (<18 years) who were seen for a skin condition at the ED from December 1, 2017, to June 1, 2018, and consented to participate. We classified diagnoses according to their etiology. Patients were diagnosed by ED trainees and attending physicians, followed by blinded pediatric dermatology trainees and attending physicians. We evaluated concordance using Fleiss's kappa coefficient (κ) with a 95% confidence interval. We further stratified the data by level of training. RESULTS: We included 185 patients. Inflammatory conditions were the most common reason for consultation, followed by infections; 10 patients required hospitalization. Concordance between diagnoses given at the ED and at the dermatology clinic was moderate (κ 0.472, 95% CI: 0.389-0.455) with 62.7% agreement. Concordance between different diagnostic categories was lowest for autoimmune disorders and drug reactions (κ 0.392 with 95% CI: 0.248-0.536 and κ 0.258 with 95% CI: 0.114-0.402). CONCLUSIONS: Diagnostic concordance between ED physicians and dermatologists was moderate and differed according to training level and diagnoses. Dermatological education for ED providers, specifically focusing on autoimmune disorders and drug reactions, may improve diagnostic accuracy and patient care.

BACKGROUND/OBJECTIVES: Acute graft-versus-host disease (aGVHD) is a serious condition after allogeneic hematopoietic stem cell transplantation (HSCT), frequently involving skin, gut, and liver. It can be difficult to diagnose early, yet this is vital for adequate management. We sought to identify initial clinical and histopathological features in children with suspected GVHD and the association with clinical course and outcomes. METHODS: Retrospective study of patients with skin biopsies for suspected aGVHD from 2006 to 2016. We collected demographic and clinical information, histologic, and immunohistochemical (IHC) findings, and outcomes during follow-up. Bivariate and multivariate analyses were done to identify risk factors associated with remission, development of severe/life-threatening aGVHD, and mortality. RESULTS: We included 42 patients, 15 females. Skin manifestations occurred 51 days (median) after HSCT. On biopsy, 76.2% had mild (stage 1-2) skin aGVHD; during the course of the disease, severity and systemic involvement increased to global grade III/IV in 66.6%. All patients received treatment; 15 are in remission from aGVHD and 23 have died. Histologic features were diagnostic in 83.3%. On bivariate and multivariate analysis, we identified initial clinical and histologic findings that were associated with the measured outcomes: odds of remission from aGVHD were increased when focal vacuolar changes were found on skin biopsy (OR 6.028; 95%CI:1.253-28.992) but decreased by initial hepatic aGVHD (OR 0.112; 95%CI: 0.017-0.748); severe/life-threatening aGVHD was associated with initial gastrointestinal aGVHD (OR 6.054; 95%CI:1.257-29.159); and odds of mortality were decreased with male donor (OR 0.056; 95%CI:0.004-0.804), nulliparous female donor (OR 0.076; 95%CI:0.009-0.669), and focal vacuolar changes on skin biopsy (OR 0.113; 95%CI:0.017-0.770). CONCLUSIONS: We found novel indicators predictive of remission, severity, and mortality in children with aGVHD. Further studies of this condition in children are needed.

Morphea, or localized scleroderma, is a rare disease of the connective tissue that manifests itself with localized sclerosis of the skin and, in some cases, with extracutaneous manifestations. Its etiology is not fully understood, but it is believed that there is genetic predisposition, in addition to environmental triggering factors. Classification of the disease is not simple due to its multiple presentations; however, it is useful in order to define the treatment, which should be individualized and started early to avoid cosmetic and functional complications. In this review, we summarize the most important practical aspects of the classification, diagnostic methods and evaluation of morphea activity, as well as available therapeutic options, with an emphasis on existing clinical evidence regarding their efficacy and safety.

La morfea o esclerodermia localizada es una enfermedad poco común del tejido conectivo que se manifiesta con esclerosis localizada de la piel y, en algunos casos, con lesiones extracutáneas. Su etiología no se comprende por completo, pero se cree que hay predisposición genética, además de factores ambientales desencadenantes. La clasificación de la enfermedad no es sencilla debido a las múltiples presentaciones, sin embargo, es útil para definir el tratamiento, el cual debe individualizarse e iniciarse tempranamente para evitar complicaciones cosméticas y funcionales. En esta revisión resumimos los aspectos prácticos más importantes de la clasificación, métodos diagnósticos y de evaluación de actividad en morfea, así como las opciones terapéuticas disponibles, con énfasis en la evidencia clínica existente respecto a su eficacia y seguridad.

BACKGROUND: Neurofibromatosis type 1 (NF1) is a neurocutaneous disorder caused by loss-of-function mutation in the NF1 gene. Segmental or mosaic NF1 (MNF) is an uncommon presentation of the NF1 result of postzygotic mutations that present with subtle localised clinical findings. OBJECTIVES: Our study's objectives were to describe the clinical characteristics of children with MNF. METHODS: We conducted a cross-sectional study of children diagnosed with MNF at the Hospital for Sick Children in Toronto, Canada, from January 1992 to September 2012. Data were abstracted from health records and analysed using a standardised data collection form approved by our hospital Research Ethics Board. RESULTS: We identified 60 patients with MNF; 32 of 60 (53.3%) were female. Mean ± SD age at first assessment was 10.6 ± 4.6 years. The most common initial physical manifestation in 39 of 60 (65.0%) patients was localised pigmentary changes only, followed by plexiform neurofibromas only in 10 of 60 (16.7%) and neurofibromas only in 9 of 60 (15.0%). Unilateral findings were seen in 46 of 60 (76.7%) patients. Most common associations identified included learning disabilities (7/60; 12%) and bony abnormalities (6/60; 10.0%). CONCLUSIONS: MNF is an underrecognised condition with potential implications for patients. Children mostly present with pigmentary anomalies only. Most patients do not develop associated findings or complications before adulthood, but long-term follow-up will help determine outcomes and possible associations. Recognition and confirmation of the diagnosis is important to provide follow-up and genetic counselling to patients.

Confusion is widespread regarding segmental or mosaic neurofibromatosis type 1 (MNF1). Physicians should use the same terms and be aware of its comorbidities and risks. The objective of the current study was to identify and synthesize data for cases of MNF1 published from 1977 to 2012 to better understand its significance and associations. After a literature search in PubMed, we reviewed all available relevant articles and abstracted and synthetized the relevant clinical data about manifestations, associated findings, family history and genetic testing. We identified 111 articles reporting 320 individuals. Most had pigmentary changes or neurofibromas only. Individuals with pigmentary changes alone were identified at a younger age. Seventy-six percent had localized MNF1 restricted to one segment; the remainder had generalized MNF1. Of 157 case reports, 29% had complications associated with NF1. In one large case series, 6.5% had offspring with complete NF1. The terms "segmental" and "type V" neurofibromatosis should be abandoned, and the correct term, mosaic NF1 (MNF1), should be used. All individuals with suspected MNF1 should have a complete physical examination, genetic testing of blood and skin, counseling, and health surveillance.

Because of travel and migration patterns, tropical skin diseases are now seen all around the world, not just in tropical or developing countries. Nutrition, housing, and environmental factors play an important role in these infectious diseases, so when they appear out of their normal environments, their classic presentation may vary. Tropical diseases can also present differently in childhood, making their recognition, diagnosis, and management a clinical challenge. Health care providers in developed countries need to be familiar with tropical skin diseases and be able to diagnose them in returning travelers or immigrants in order to optimize care. This article aims to review the epidemiologic, clinical, diagnostic, and therapeutic aspects of some of the most common tropical dermatologic conditions in children.

Tropical skin diseases are infectious conditions influenced by factors such as nutrition, housing, and the environment. Migration patterns have caused these conditions to be seen all around the world, not only in developing countries. Many of these diseases have a different presentation in childhood, which changes the diagnostic approach and management options. In this article, we review some of the most common tropical mycobacterial, protozoan, parasitic, and viral dermatologic conditions in children, including their epidemiologic, clinical, diagnostic, and therapeutic aspects.
