A case of restrictive dermopathy in a Hutterite newborn: Diagnosis and creative skin-directed management.

Restrictive dermopathy is a lethal autosomal recessive disease characterized by tightly adherent skin, distinctive facial dysmorphisms, arthrogryposis, and pulmonary hypoplasia. While clinical findings are unique, histopathology and genetic analysis are critical for early diagnostic confirmation and to initiate appropriate management for this lethal disease. We report on a preterm Hutterite male neonate with biallelic ZMPSTE24 mutations to highlight the clinical and histopathological features of restrictive dermopathy and share our skin-directed management strategies.

Epidemiology and Healthcare Expenditure for Skin Disease in Emergency Departments in Alberta, Canada.

BACKGROUND: There are limited data on the epidemiology and costs associated with managing dermatologic conditions in emergency departments (EDs). OBJECTIVE: To assess the incidence and mean cost per case of skin diseases in EDs in Alberta. METHODS: Alberta Health Services' Interactive Health Data Application was used to determine the epidemiology and costs associated with nonneoplastic dermatologic diseases in EDs in the province of Alberta, Canada, from 2018 to 2022. Skin conditions were identified using the International Classification of Disease 10th edition diagnostic groupings. RESULTS: Skin disease represented 3.59% of all ED presentations in Alberta in 2022. The total costs associated with managing dermatologic conditions have remained stable over time at approximately 15 million Canadian Dollars (CAD) annually, but the mean cost per case has risen from 188.88 (SD 15.42) in 2018 to 246.25 CAD (SD 27.47) in 2022 (7.59%/year). Infections of skin and subcutaneous tissue were the most expensive diagnostic grouping. The most common dermatologic diagnostic groupings presenting to the ED were infections of skin and subcutaneous tissue [mean age-standardized incidence rate (ASIR) of 143.67 per 100,000 standard population (SD 241.99)], urticaria and erythema [mean ASIR 33.57 per 100,000 standard population (SD 59.13)], and dermatitis and eczema [mean ASIR 18.59 per 100,000 standard population (SD 23.65)]. Cellulitis was both the most common and the costliest individual diagnosis. The majority of patients were triaged as less urgent or nonurgent. CONCLUSIONS: Skin disease represents a substantial public health burden in EDs. Further research into drivers of cost change and areas for cost savings is essential.

Infections in Children Aged 6 Months to 5 Years Treated with Dupilumab in a Placebo-Controlled Clinical Trial of Moderate-to-Severe Atopic Dermatitis.

BACKGROUND: Patients with atopic dermatitis (AD), particularly infants and young children, are at greater risk of developing skin infections. In this study, we assessed infection rates in AD patients aged 6 months to 5 years treated with dupilumab. METHODS: In LIBERTY AD PRESCHOOL, a double-blind, placebo-controlled, phase III clinical trial, children aged 6 months to 5 years with moderate-to-severe AD were randomized 1:1 to subcutaneous dupilumab or placebo, with concomitant low-potency topical corticosteroids, every 4 weeks for 16 weeks. Exposure-adjusted infection rates were used to compare treatment groups. RESULTS: The analysis included 162 patients, of whom 83 received dupilumab and 79 received placebo. Total infection rates were not significantly different between the dupilumab and placebo groups (rate ratio [RR] 0.75, 95% CI 0.48-1.19; p = 0.223). Non-herpetic adjudicated skin infections and bacterial infections were significantly less frequent with dupilumab versus placebo (non-herpetic skin infections: RR 0.46, 95% CI 0.21-0.99; p = 0.047; bacterial infections: RR 0.09, 95% CI 0.01-0.67; p = 0.019), and the number of patients using systemic anti-infective medication was significantly lower in the dupilumab group (RR 0.52, 95% CI 0.30-0.89; p = 0.019). There were no significant differences in the number of herpetic infections between the dupilumab and placebo groups (RR 1.17, 95% CI 0.31-4.35; p = 0.817). The number of patients with two or more infection events was significantly higher in the placebo group (RR 0.29, 95% CI 0.12-0.68; p = 0.004), and no severe or serious infections (including eczema herpeticum) were observed among patients receiving dupilumab. CONCLUSIONS: These data suggest that dupilumab treatment in infants and children younger than 6 years with AD does not increase overall risk of infections and is associated with a reduced risk of bacterial and non-herpetic skin infections compared with placebo, resulting in a reduced need for anti-infective medication. TRIAL REGISTRATION: The trial was registered with ClinicalTrials.gov with ID number NCT03346434 on November 17, 2017. INFOGRAPHIC.

Patients with atopic dermatitis (AD), a chronic disease of the skin, are at greater risk of developing skin infections, particularly infants and young children. Several medications for AD may weaken the patient's immune system, further increasing the risk of infections. Dupilumab is a recently developed drug for AD that should not interfere with the patient's immune defenses against bacterial, viral, or fungal infections. In this study, we evaluated the effect of dupilumab on infections in children aged 6 months to 5 years with moderate-to-severe AD. Patients received 200 or 300 mg of dupilumab (depending on the child's weight) or placebo, together with ointments containing mild steroids, every 4 weeks for 16 weeks. At the end of treatment, total infections were not significantly different between patients receiving dupilumab and placebo. Furthermore, patients receiving dupilumab experienced significantly less bacterial and non-herpetic skin infections and used significantly less anti-infective medication compared with patients receiving placebo. Herpetic infections were also not significantly different between dupilumab- and placebo-treated patients. Finally, significantly more patients in the placebo group experienced two or more infections. This study demonstrates that dupilumab does not increase the risk of infections in infants and young children with AD and can decrease the use of anti-infective medication.

Stigmatization and Mental Health Impact of Chronic Pediatric Skin Disorders.

Importance: Chronic skin disorders in children frequently are visible and can cause stigmatization. However, the extent of stigmatization from chronic skin disease and association with mental health needs further study. Objective: To examine the extent of stigma, dependence on disease visibility and severity, and association with mental health and quality of life (QOL) in chronic pediatric skin disease. Design, Setting, and Participants: A cross-sectional, single-visit study was conducted at 32 pediatric dermatology centers in the US and Canada from November 14, 2018, to November 17, 2021. Participants included patients aged 8 to 17 years with chronic skin disease and 1 parent. Main Outcomes and Measures: Using the Patient-Reported Outcomes Measurement Instrumentation System (PROMIS) Stigma-Skin, the extent of stigma with child-, caregiver-, and physician-assessed disease visibility (primary outcome) and severity was compared, as well as reduced QOL (assessed by Skindex-Teen), depression, anxiety, and poor peer relationships (PROMIS child and proxy tools) (secondary outcomes). Results: The study included 1671 children (57.9% female; mean [SD] age, 13.7 [2.7] years). A total of 56.4% participants had self-reported high disease visibility and 50.5% had moderate disease severity. Stigma scores significantly differed by level of physician-assessed and child/proxy-assessed disease visibility and severity. Among children with chronic skin disorders, predominantly acne, atopic dermatitis, alopecia areata, and vitiligo, only 27.0% had T scores less than 40 (minimal or no stigma) and 43.8% had at least moderate stigma (T score ≥45) compared with children with a range of chronic diseases. Stigma scores correlated strongly with reduced QOL (Spearman ρ = 0.73), depression (ρ = 0.61), anxiety (ρ = 0.54), and poor peer relationships (ρ = -0.49). Overall, 29.4% of parents were aware of bullying of their child, which was strongly associated with stigma (Cohen d = -0.79, with children who were not bullied experiencing lower levels of stigma). Girls reported more stigma than boys (Cohen d = 0.26). Children with hyperhidrosis and hidradenitis suppurativa were most likely to have increased depression and anxiety. Conclusions and Relevance: The findings of this study suggest that physician assessment of disease severity and visibility is insufficient to evaluate the disease impact in the patient/caregiver. Identifying stigmatization, including bullying, and tracking improvement through medical and psychosocial interventions may be a key role for practitioners.
