Management and Long-Term Outcomes of Drug Reaction with Eosinophilia and Systemic Symptoms (DReSS) in Children: A Scoping Review.

Drug reaction with eosinophilia and systemic symptoms (DReSS) is known to cause mortality and long-term sequelae in the pediatric population, however there are no established clinical practice guidelines for the management of pediatric DReSS. We conducted a scoping review, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, to summarize the currently available data on treatment, mortality, and long-term sequelae of DReSS in children (aged 0-18 years). Data from 644 individuals revealed that various treatment strategies are being used in the management of pediatric DReSS, and strategies were often used in combination. The diversity in treatment approaches cannot be solely attributed to age or disease severity and reflects the lack of evidence-based management guidelines for DReSS. Children are also at risk of developing autoimmune sequelae following DReSS, most commonly thyroid disease and type 1 diabetes mellitus. We found that the eventual development of autoimmune disease was more often associated with DReSS caused by antibiotics, especially minocycline and sulfamethoxazole, in comparison with individuals who did not develop sequelae. In this study, we identify strengths and weaknesses in the currently available literature and highlight that future prospective studies with structured and long-term follow-up of children with DReSS are needed to better understand potential risk factors for mortality and development of sequelae after DReSS.

Single dominant lesion in capillary malformation-arteriovenous malformation (CM-AVM) RASA1 syndrome.

We report two cases with localized vascular malformations clinically resembling the "dominant lesion" seen in capillary malformation-arteriovenous malformation (CM-AVM) syndrome, however, lacking germline RASA1 variants but presenting double somatic RASA1 variants in affected tissue. Both patients presented with localized and superficial high-flow vascular malformations were treated with surgery and laser therapy and showed partial resolution. The study underscores the rarity of somatic RASA1 variants, contributes to understanding the "second-hit" pathophysiology in vascular lesions, and emphasizes the significance of clinical distinctions and genotyping for accurate diagnoses, offering implications for diagnosis, prognosis, and genetic counseling.

Clinical Presentation and Diagnosis of Drug Reaction with Eosinophilia and Systemic Symptoms (DReSS) in Children: A Scoping Review.

Effective treatment of drug reactions with eosinophilia and systemic symptoms (DReSS) requires early diagnosis and close monitoring. Diagnosing DReSS is especially challenging in children due to a low incidence rate, heterogeneous clinical presentation, and a lack of (pediatric) diagnostic criteria and clinical practice guidelines. We performed a scoping review, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, to summarize the clinical presentation and diagnostic process of DReSS in children (aged 0-18 years). Data from 644 individuals showed that DReSS manifests differently in children compared to adults. Children have a higher number of organs involved, including higher rates of cardiac and respiratory involvement compared to adults. Children < 6 years of age appear more prone to develop neurologic symptoms. Conversely, eosinophilia, edema, and kidney involvement are less frequently observed in children. Anti-seizure medications are by far the most common causative drug class, but the range of implicated drugs increases as children get older. This study highlights that children with DReSS not only differ from adults but also that differences exist between children of different ages. As such, there is a need to establish pediatric-specific diagnostic criteria. These efforts will promote earlier diagnosis of DReSS and likely lead to improved clinical care offered to children and their families.

Characteristics and onset of presentation of pediatric stiff skin syndrome: A retrospective cohort study of 11 patients in a tertiary care center.

BACKGROUND/OBJECTIVE: Stiff skin syndrome (SSS) is a rare disorder characterized by "rock hard" indurated skin affecting different body parts. The localized variant poses a diagnostic challenge, as it is frequently mistaken for other inflammatory connective tissue disorders. The aim of this study is to provide insightful clinical, radiologic and diagnostic data that might prove useful for the evaluation, management and treatment of pediatric patients with segmental SS. METHODS: This single-center cohort study included patients ≤18 years diagnosed with localized SSS from 1988 to 2021 in a quaternary pediatric healthcare center in Toronto, Canada. Data included demographics, clinical, histopathologic and radiologic features, treatments, and clinical course. Data were summarized with descriptive statistics (mean, standard deviation, medians, interquartile ranges [IQRs]) and frequencies. RESULTS: A total of 11 patients were included. The sclerotic changes were measured clinically and radiologically, by a total of 16 imaging studies: 13 magnetic resonance imaging (MRI) and 3 ultrasound. MRI readings showed abnormal high signal intensity of the affected tissue correlating with the anatomical site of involvement in all cases, specifically, in the shoulder/pelvic girdle with limb extension. Shear wave ultrasound elastography (SWE) demonstrated higher values within the dermis compared to the control site. CONCLUSION: The presence of segmental sclerotic changes that affects the pelvic/shoulder girdle with extension to the extremities, in the absence of inflammation on biopsy and abnormal signaling intensity on imaging is suggestive of SSS. Skin SWE is a feasible, noninvasive, and objective instrument to evaluate and monitor sclerotic changes overtime, it could be potentially extrapolated to other pediatric skin sclerotic conditions.

Systematic Review of Health-Related Quality of Life Impact in Juvenile Localized Scleroderma.

OBJECTIVE: The prevalence and types of psychosocial complications of juvenile localized scleroderma (JLS), also known as morphea, an inflammatory and sclerosing disease involving the skin, fascia, muscle, and bone, are poorly understood. METHODS: We performed a systematic review of literature published between 2000 and 2020 in PubMed, EMBASE, the Cochrane Skin Group Specialized Register, the Cochrane Central Register of Controlled Trials, and the Cumulative Index to Nursing and Allied Health Literature using the search terms "scleroderma, localized," "Morphea," "anxiety," "depression," "resilience," "social stigma," "quality of life," "mood," or "stress" and limited the search to pediatric patients and English language. Patient demographics, characteristics of JLS, and comorbidities were extracted. The outcomes included measures of health-related quality of life (HRQoL), psychosocial functioning, evaluation of self-perception, and the treatment burden of the study population. The protocol was registered with PROSPERO (CRD42021257124). Thematic synthesis generated descriptive analysis. RESULTS: Thirteen studies fulfilled the inclusion criteria: three retrospective cohort studies, two prospective cohort studies, and eight cross-sectional studies. A total of 690 pediatric patients with JLS were included (n = 484 with linear scleroderma). Six studies used the Children's Dermatology Life Quality Index, reporting little to no effect on HRQoL. One study used the Health-Related Quality of Life in Children and Adolescents Questionnaire and did not find differences between children with JLS or atopic dermatitis and healthy controls. One study used a self-perception questionnaire that showed normal self-worth of patients with JLS. Two studies used focus groups, both reporting elevated levels of stress, decreased self-worth, "feeling different," and bullying/teasing in patients with JLS. These emotions were associated with skin symptoms (pain, itch, and tightness), physical limitations, and treatment burden. CONCLUSION: Overall, quantitative studies did not report a statistically significant impairment in HRQoL in JLS. However, qualitative studies (focus groups) reported significant psychosocial impacts related to JLS. There is a need to develop a JLS-specific tool for the HRQoL evaluation of this population.

Sturge-Weber Syndrome: A Review of Pathophysiology, Genetics, Clinical Features, and Current Management Approache.

Sturge-Weber syndrome (SWS) is a congenital, sporadic, and rare neurocutaneous disorder, characterized by the presence of a facial port-wine birthmark (PWB), glaucoma, and neurological manifestations including leptomeningeal angiomatosis and seizures. It is caused by a postzygotic, somatic, gain-of-function variant of the GNAQ gene, and more recently, the GNA11 gene in association with distinctive clinical features. Neuroimaging can help identify and stratify patients at risk for significant complications allowing closer follow-up; although no presymptomatic treatment has been demonstrated to be effective to date, these patients could benefit from early treatment and/or supportive interventions. Choroid plexus (CP) thickness measurements in brain magnetic resonance imaging (MRI) have a high sensitivity and specificity for early and incipient changes in SWS. In contrast, the absence of pathologic findings makes it possible to rule out associated neurological involvement and leads to periodical observation, with new imaging studies only in cases of new clinical signs/symptoms. Periodic ophthalmological examination is also recommended every 3 months during the first year and yearly afterwards to monitor for glaucoma and choroidal hemangiomas. Treatment for SWS depends on the extent and areas that are affected. These include laser surgery for PWB, anticonvulsants in the case of brain involvement, with either seizures or abnormal EEG, and medical treatment or surgery for glaucoma. Sirolimus has been used in a limited number of patients and appears to be a safe and potentially effective treatment for cutaneous and extra-cutaneous features, however controlled clinical studies have not been carried out. Better knowledge of GNAQ/GNA11 molecular pathways will help to develop future targeted treatments.

An educational intervention to implement skin-to-skin contact and early breastfeeding in a rural hospital in Mexico.

Background: Early skin-to-skin contact promotes infant physiologic stability, provides warmth and makes breast milk readily available. Despite the known benefits of early skin-to-skin contact, this practice is not included within standard care in the Mexican public healthcare system. After birth, newborns are usually taken to an incubator in the nursery where they transition to extrauterine life and receive either dextrose 5% or infant formula for their first feed. The aim of this study was to assess if a dual educational intervention in a rural hospital in Mexico could modify current practice and accomplish early skin-to-skin contact and early breastfeeding. Methods: A two-step educational intervention was designed. The first step was to educate the labor and birthing staff of the hospital, and the second step was to educate all pregnant women with uncomplicated pregnancies at 36 weeks' gestation. The educational intervention explored the benefits, implications and steps of early skin-to-skin contact and early breastfeeding. All births were registered for the three month period following the intervention. The time of onset of skin-to-skin (SSC) contact, its duration and time of initiation of breastfeeding were recorded and analyzed using ANOVA testing. Results: A total of 142 births met our inclusion criteria, from those, 77% (n = 109) received skin-to-skin contact and early breastfeeding. The average time of initiation of skin-to-skin contact in the first and last month of the study was 18.5 (± 2.2) and 9.6 (± 2.2) minutes of life, respectively (p < 0.001). The average duration of SSC in the first and last month was 22 (± 10.9) and 40.9 (± 17.4) minutes, respectively (p < 0.001). The average time of onset of breastfeeding in the first and last month was 48.9 (± 15) and 34.4 (± 16.7) minutes of life, respectively (p < 0.001). Conclusions: A simple and low-cost educational intervention achieved the inclusion of skin-to-skin contact and early breastfeeding as part of standard care in a rural hospital. Further studies could replicate our intervention in similar settings to test the generalizability of the findings.
