RESUMEN

BACKGROUND: Atopic dermatitis (AD) is a chronic, pruritic disorder affecting 10-20% of children and is associated with psychological issues and impaired quality of life (QoL). The role of psychosocial support in the treatment of AD is increasingly important. We studied the impact of a multidisciplinary clinic (MDC) in the management of AD in a tertiary children's hospital in Singapore. METHODS: We performed a prospective pilot interventional study on 34 pediatric patients with AD and concomitant psychosocial impairment. Patients were recruited into an MDC, comprising a dermatologist, clinical psychologist and medical social worker. AD severity was scored using Scoring Atopic Dermatitis (SCORAD), while QoL was assessed using the Children's Dermatology Life Quality Index Questionnaire (CDLQI) and Family Dermatology Life Quality Index Questionnaire (FDLQI). Biopsychosocial assessments and interventions were also performed. Eighty-three percent of patients received cognitive behavioral therapy, while 40% received social work intervention. RESULTS: There was an overall improvement in mean SCORAD, CDLQI, and FDLQI scores across MDC visits. A correlation between AD severity and QoL was established. A patient satisfaction survey showed improvement in severity, understanding, and control of the disease. CONCLUSION: Our study suggests the effectiveness of a multidisciplinary approach in managing pediatric AD patients with psychosocial co-morbidities.

RESUMEN

INTRODUCTION: Moisturizers are one of the mainstays of the topical treatment of atopic dermatitis (AD). One of the adverse effects of moisturizers is skin irritation, especially on excoriated AD skin. We compared the potential for irritation of two commercially available moisturizer products for the treatment of AD: a ceramide-based moisturizer (Ceradan® Cream; Hyphens Pharma Pte Ltd, Singapore) and a urea 5% moisturizer (Aqurea Lite Cream; ICA Pharma Pte Ltd, Singapore). METHODS: We performed a prospective single-blind randomized controlled study recruiting AD patients aged between 8 and 16 years with symmetrical or near symmetrical scratch marks (excoriations) of at least grade 2 to 3 severity score, according to the Eczema Area and Severity Index (EASI), over bilateral antecubital fossae. Subjects were randomized to receive the ceramide-based moisturizer to either the left or right antecubital fossa or urea 5% cream to the other antecubital fossa. Subjects were asked to grade the immediate skin irritation of both creams on a standard visual analogue scale (VAS) and which cream they would prefer to use as a daily moisturizer. Primary outcome was the mean irritant score of each cream, and secondary outcome was the subjects' preference of either cream as their daily moisturizer. RESULTS: A total of 42 participants were enrolled with a mean age of 11 years 5 months. The ceramide-based cream had a significantly lower mean VAS score (mean 0.69, SD = 1.63) for irritation compared with urea 5% cream (1.43, SD = 1.64) (p = 0.035). More participants also preferred the ceramide-based cream over urea 5% cream (62% versus 38%) as their daily moisturizer, but this did not reach statistical significance (p = 0.164). CONCLUSIONS: A ceramide-based moisturizer may be considered as a suitable choice for children to minimize irritation from moisturizer treatment for AD.

RESUMEN

INTRODUCTION: Patient eczema severity time (PEST) is a new atopic dermatitis (AD) scoring system based on patients' own perception of their disease. Conventional scales such as SCORing of atopic dermatitis (SCORAD) reflect the clinician's observations during the clinic visit. Instead, the PEST score captures eczema severity, relapse and recovery as experienced by the patient or caregiver on a daily basis, promoting patient engagement, compliance with treatment and improved outcomes. This study aims to determine the correlation between carer-assessed PEST and clinician-assessed SCORAD in paediatric AD patients after 12 weeks of treatment using a ceramide-dominant therapeutic moisturizer. METHODS: Prospective, open-label, observational, multi-centre study in which children with AD aged 6 months to 6 years were treated with a ceramide dominant therapeutic moisturizer twice daily for 12 weeks; 58 children with mild-to-moderate AD were included. Correlation between the 7-day averaged PEST and SCORAD scores for assessment of AD severity was measured within a general linear model. PEST and SCORAD were compared in week 4 and week 12. RESULTS: At week 12, a moderate correlation was found between the SCORAD and PEST scores (r = 0.51). The mean change in SCORAD and PEST scores from baseline to week 12 was -11.46 [95% confidence interval (CI) -14.99 to -7.92, p < 0.0001] and -1.33 (95% CI -0.71 to -0.10, p < 0.0001) respectively. PEST demonstrated greater responsiveness to change (33.3% of scale) compared to SCORAD (13.8% of scale). CONCLUSION: The PEST score correlates well with the SCORAD score and may have improved sensitivity when detecting changes in the severity of AD. The ceramide-dominant therapeutic moisturizer used was safe and effective in the management of AD in young children. FUNDING: Hyphens Pharma Pte Ltd.

RESUMEN

A 13-year-old boy underwent allogeneic hematopoietic stem cell transplantation (HSCT) for underlying acute lymphoblastic leukemia and achieved neutrophil engraftment 28 days after HSCT. He developed ichthyosis 6 weeks after HSCT and then keratotic follicular papules, palmoplantar keratoderma, and a seborrheic dermatitis-like eruption 18 weeks after HSCT. From skin biopsies he was diagnosed with eczematoid graft-versus host disease (GVHD), which showed spongiosis with scattered necrotic keratinocytes. He responded to oral and topical steroids and an increase in cyclosporine dose. Although uncommon, eczematoid GVHD must be considered in children who have undergone HSCT and then develop an atypical eczematous eruption, especially in the absence of a history of atopy.

RESUMEN

Hydroa vacciniforme is a photosensitivity disorder characterized by the childhood onset of necrotic vesiculopapules on exposed areas. We present a case of a 10-year-old boy with a 1-year history of papular lesions over his face. In this report, we discuss the in-depth histology of hydroa vacciniforme, and the management options.
