Effectiveness of a nurse-led one-to-one education programme in addition to standard care in children with atopic dermatitis: a multicentre randomized control trial.

BACKGROUND: Therapeutic patient education (TPE) is recommended for children with atopic dermatitis (AD), but no consensus has been reached on the optimal tailoring of delivery. While repeated multidisciplinary group education sessions have shown effectiveness, the benefits of one-on-one educational interventions led by nurses for children with AD have not yet been assessed. OBJECTIVES: To assess the benefits of additional, well-structured, 1-h nurse-led individual TPE interventions in children with AD and their families compared with standard care alone. METHODS: Children with moderate-to-severe AD and their parents were randomized to receive a 1-h nurse-led education session in addition to standard care vs. standard care alone. The primary outcome was the area under the curve (AUC) of the SCORing of Atopic Dermatitis index (SCORAD) from baseline to week 24 (lower AUC values represent better long-term control of the disease). RESULTS: In our study, 176 patients were randomized across 11 centres, and 153 were included in the full analysis set. The mean (SD) age was 4.47 (4.57) years. By week 24, there were no significant differences in the AUCs of the SCORAD between the two groups (P = 0.3). Secondary outcomes including patient-reported severity and quality of life [AUCs of the patient-oriented SCORAD (PO-SCORAD) and Infants' Dermatitis Quality of Life Index (IDLQI), Children's Dermatitis Quality of Life Index (CDLQI) and Family Dermatitis Quality of Life Index (FDLQI)] were not significantly different between the two groups. The only significant change observed in the intervention group, when compared with the one receiving standard care, was a decrease in topical steroid phobia, as assessed by the topical corticosteroid phobia (TOPICOP) score. Prespecified subgroup analyses showed that disease severity in the intervention group was significantly lower throughout the study, compared with the standard-care group when participants had moderate AD at baseline (n = 47); while participants with severe AD at baseline (n = 106) did not show benefit from the intervention. Participants showed no additional benefit from the intervention regardless of age group. CONCLUSIONS: This study did not show any additional effectiveness, in long-term severity control, of a 1-h nurse-led TPE intervention in children with AD treated with standard care, compared with those treated with standard care alone. However, it should be noted that the intervention reduced the fear of using topical steroids and may be beneficial for patients in the subgroup with moderate AD.

Atopic dermatitis (AD), also known as atopic eczema, is a chronic relapsing disease that affects 7­15% of children worldwide. Therapeutic patient education (TPE) is recommended for children with AD, but no agreement has been reached on the best way to tailor delivery. While repeated multidisciplinary group education sessions in a hospital setting have been found effective, this type of intervention requires a lot of resources and is time-consuming. To assess the benefits of TPE in children with AD, researchers in France carried out this study with children with moderate-to-severe AD, to compare a 1-hour nurse-led education session in addition to standard care vs. standard care alone. The main aim of this research was to assess the effectiveness of a TPE intervention over a period of 6 months, using a measurement tool called the SCORAD (SCORing of Atopic Dermatitis index). We found no additional benefits in terms of long-term severity control and quality of life at 6 months of a 1-hour nurse-led education intervention in children with AD treated with standard care. However, it should be noted that the intervention reduced the fear of using topical steroids and may be beneficial for people in the moderate AD subgroup.

Anti-BP180 IgG antibody ELISA values correlate with adverse pregnancy outcomes in pemphigoid gestationis.

BACKGROUND: Adverse pregnancy outcomes (APO) occur in 35% of patients with pemphigoid gestationis (PG). No biological predictor of APO has been established yet. OBJECTIVES: To assess a potential relationship between the occurrence of APO and the serum value of anti-BP180 antibodies at the time of PG diagnosis. METHODS: Multicentre retrospective study conducted from January 2009 to December 2019 in 35 secondary and tertiary care centres. INCLUSION CRITERIA: (i) diagnosis of PG according to clinical, histological and immunological criteria, (ii) ELISA measurement of anti-BP180 IgG antibodies determined at the time of PG diagnosis with the same commercial kit and (iii) obstetrical data available. RESULTS: Of the 95 patients with PG included, 42 had one or more APO, which mainly corresponded to preterm birth (n = 26), intrauterine growth restriction (IUGR) (n = 18) and small weight for gestational age at birth (n = 16). From a ROC curve, we identified a threshold of 150 IU ELISA value as the most discriminating to differentiate between patients with or without IUGR, with 78% sensitivity, 55% specificity, 30% positive and 91% negative predictive value. The threshold >150 IU was confirmed using a cross-validation based on bootstrap resampling, which showed that the median threshold was 159 IU. Upon adjusting for oral corticosteroid intake and main clinical predictors of APO, an ELISA value of >150 IU was associated with the occurrence of IUGR (OR = 5.11; 95% CI: 1.48-22.30; p = 0.016) but not with any other APO. The combination of blisters and ELISA values higher than 150 IU led to a 2.4-fold higher risk of all-cause APO (OR: 10.90; 95% CI: 2.33-82.3) relative to patients with blisters but lower values of anti-BP180 antibodies (OR of 4.54; 95% CI 0.92-34.2). CONCLUSION: These findings suggest that anti-BP180 antibody ELISA value in combination with clinical markers is helpful in managing the risk of APO, in particular IUGR, in patients with PG.

Perialar intertrigo in children and adolescents: A multicenter prospective study of 41 cases.

BACKGROUND/OBJECTIVES: We observed isolated cases of perialar intertrigo in children and teenagers that did not appear to correspond to any known clinical entity. The objective of this study was to describe the clinical features of this dermatosis and the clinical characteristics of the patients. METHODS: We conducted a prospective, multicenter cohort study in France from August 2017 to November 2019. All the patients under 18 years of age with chronic perinasal intertrigo were included. A standardized questionnaire detailing the clinical characteristics of the patients and the description of the intertrigo. If possible, a Wood's lamp examination of the intertrigo was done. RESULTS: Forty-one patients were included (25 boys and 16 girls, average age: 12.1 years). Intertrigo was bilateral in 38 patients (93%). The majority of patients had no symptoms (54%). Pruritus was present in 39% of cases. Orange red follicular fluorescence was present in the perialar region on Wood's light examination in 78% of cases with active fluorescence. The presumptive diagnoses suggested by the investigators were acne (24.4%), seborrheic dermatitis (19.5%), rosacea (9.8%), psoriasis (9.8%) and perioral dermatitis (7.3%). No diagnosis was proposed in 22% of the cases. CONCLUSIONS: We describe a previously undescribed clinical sign which is characterized by a chronic bilateral erythematous intertrigo located in the perialar region. It can be isolated or associated with various facial dermatoses.

Switching biologics in children with psoriasis: Results from the BiPe cohort.

BACKGROUND: There is currently little information on switching biologics in pediatric psoriasis. OBJECTIVE: To evaluate the real-world clinical practice and safety of switching biologics in the "Biological Treatments for Pediatric Psoriasis" (BiPe) cohort. METHODS: Data for all 134 patients included in the BiPe cohort were analyzed. A further evaluation of the subpopulation of patients who switched from a first-line biologic to a second-line biologic was then conducted. Drug survival rates were also compared between biologics given as first-line or second-line agents. RESULTS: Overall, 29 patients (female: 55%; mean age: 16.6 ± 3.0 years) switched between two biologics. Etanercept (ETN) was the first-line biologic used in 23 patients: 16 (69.6%) switched to adalimumab (ADA) and seven (30.4%) to ustekinumab (UST). Six patients received first-line ADA and switched to UST. Loss of efficacy (62.1%), primary inefficacy (20.7%), and parental choice (6.9%) were the main reasons for switching biologics. One (3.4%) of the switches was performed because of adverse events or intolerance. For UST and ADA, the 18-month drug survival rate did not differ according to whether the agent was given as a first-line or second-line biologic (UST: P = .24; ADA: P = .68). No significant differences in drug survival rates were observed between the three different switches (ADA to UST, ETN to ADA, and ETN to UST). CONCLUSION: Our study provided key insights into the real-life clinical practice of switching biologics in pediatric psoriasis patients. However, more information and guidance on switching biologics in pediatric psoriasis are needed to improve real-life practice and outcomes.

Teledermatology in Times of COVID-19 Confinement: Comparing Patients' and Physicians' Satisfaction by the Standardized Brest Teledermatology Questionnaire.

The French government imposed the first COVID-19 pandemic lockdown from March 17 until May 11, 2020. Only emergency cases and teledermatology (TD) were allowed in outpatient settings. A standardized questionnaire was developed to compare the satisfaction level of patients and their treating physicians. Our main question was whether the patients would perceive TD as a valid alternative for direct physical face-to-face consultation. Eighty-two patients and their 4 treating dermatologists from one dermatology department participated in the study (43 females, 39 males) with a mean age of 46.6 years (SD ±23.9). The reason for TD was a chronic disease in the majority (87.8%), and mainly as a follow-up (96.3%). Regarding satisfaction, almost all categories rated around 9 on a 0-10 verbal analogue scale. The same level of global satisfaction could be seen between the patients and the physicians as well as for the quality of the patient-physician relation and whether all questions could be addressed during the TC. Physicians showed significantly higher scores than patients only for the category of "length" of the consultation. Gender, age, as well as distance between the clinic and home of the patient were not influencing factors for satisfaction. Regarding the technical parameters, the evaluation was mostly comparable for patients and physicians, but overall lower than the relational satisfaction parameters, especially for image quality. Patients were significantly more motivated to continue the TD after the lockdown than their treating dermatologists. We see an interest for implementing TD in specialized centers with chronic patients coming from remote places for regular follow-ups. TD cannot replace in-person patient-physician interaction, but was helpful during the lockdown. As a result, TD might become part of dermatology training to prepare for future lockdown situations.

The scalp hair collar and tuft signs: A retrospective multicenter study of 78 patients with a systematic review of the literature.

BACKGROUND: Hair collar sign (HCS) and hair tuft of the scalp (HTS) are cutaneous signs of an underlying neuroectodermal defect, but most available data are based on case reports. OBJECTIVE: We sought to define the clinical spectrum of HCS and HTS, clarify the risk for underlying neurovascular anomalies, and provide imaging recommendations. METHODS: A 10-year multicenter retrospective and prospective analysis of clinical, radiologic, and histopathologic features of HCS and HTS in pediatric patients was performed. RESULTS: Of the 78 patients included in the study, 56 underwent cranial and brain imaging. Twenty-three of the 56 patients (41%) had abnormal findings, including the following: (1) cranial/bone defect (30.4%), with direct communication with the central nervous system in 28.6%; (2) venous malformations (25%); or (3) central nervous system abnormalities (12.5%). Meningeal heterotopia in 34.6% (9/26) was the most common neuroectodermal association. Sinus pericranii, paraganglioma, and combined nevus were also identified. LIMITATIONS: The partial retrospective design and predominant recruitment from the dermatology department are limitations of this study. CONCLUSIONS: Infants with HCS or HTS are at high risk for underlying neurovascular anomalies. Magnetic resonance imaging scans should be performed in order to refer the infant to the appropriate specialist for management.

Intramuscular capillary-type hemangioma: Diagnosis, treatment, and outcomes. A French multicentric retrospective study of 66 cases.

PURPOSE: Intramuscular capillary-type hemangiomas (ICTHs) are rare entities, belonging to the group of intramuscular "hemangiomas." The diagnosis remains challenging. We aimed to assess the diagnostic criteria, treatments and outcomes of ICTHs. METHODS: This retrospective study collected all cases of ICTH followed up in 9 French hospital centers, reviewed by an adjudication expert group. RESULTS: Among 133 patients screened, 66 with ICTH were included. The median age of patients at diagnosis was 28.0 years, interquartile range (21.0---36.0). The lesion, mainly presenting as a gradually increasing mass (83.9%), was painless (88.9%) and was located in the head and neck (42.4%). MRI (available in all cases) mainly revealed a well-delineated lesion, isointense to the muscle on T1-weighted images, with enhancement after contrast injection; hyperintense on T2-weighted images; and containing flow voids. Among the 66 cases, 59 exhibited typical ICTH features and 7 shared some imaging features with arteriovenous malformations. These latter were larger than typical ICTHs and more painful and appeared on imaging as less well delimited and more heterogeneous tissue masses, with larger tortuous afferent arteries, earlier draining vein opacification and mild arteriovenous shunting. We propose to name these lesions arteriovenous malformation (AVM)-like ICTH. Pathological reports were similar in typical and AVM-like ICTH, showing capillary proliferation with mainly small-size vessels, negative for GLUT-1 and positive for ERG, AML, CD31 and CD34, with low Ki67 proliferation index (<10%), and adipose tissue. The most frequent treatment for ICTH was complete surgical resection (17/47, 36.2%), preceded in some cases by embolization, which led to complete remission. CONCLUSIONS: ICTH can be diagnosed on MRI when it is typical. Biopsy or angiography are required for atypical forms.

[A silent-growing and fast-killing melanoma in a teenager]. / Un mélanome de progression insidieuse et rapidement fatale chez une adolescente.

Malignant melanoma is a relatively rare but potentially aggressive tumor in children and adolescents. We report the case of a metastatic malignant melanoma in a 17-year-old girl, first diagnosed on cytological features of a fine-needle lymph node aspiration and then histologically confirmed by both examination of the metastatic adenopathy and a clinically harmless skin lesion of the scalp, which harbored focal microscopic pattern of melanoma. A fluorescent in situ hybridization study revealed that both metastatic and primary cutaneous tumours contained the same and pejorative chromosomal aberration consisting in CCND1 amplification (11q13). This observation raises actual limits and challenges in the fields of diagnosis and treatment of fast-killing melanomas.

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS): Series of 49 French Pediatric Cases.

BACKGROUND: Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare and potentially fatal adverse reaction. It can be difficult to diagnose, even more so among children, because symptoms may mimic other commonly encountered pediatric conditions. OBJECTIVE: To describe clinical and laboratory features of DRESS syndrome in the pediatric population (age ≤18 years) and establish causative agents and treatment modalities. METHODS: This was a multicenter retrospective study of probable and definite DRESS cases (Registry of Sever Cutaneous Adverse Reaction score ≥ 4) in children hospitalized in 15 French university hospitals between 2000 and 2020. RESULTS: We included 49 cases. All children had fever and rash, 69.4% had lymphadenopathy, and 65.3% had facial edema. The most common organ affected was the liver (83.7%). Treatment consisted of topical corticosteroid in only 30.6% and systemic corticosteroid in 55.1%; 12.2% received intravenous immunoglobulin. Among probable and likely culprit drugs, 65% were antibiotics and 27.5% were antiepileptics, median time to DRESS symptom onset after initiation of 15 days (13 days with antibiotics and 21 days with antiepileptics). Twenty-seven children had allergy assessment for causative agents, 65.4% of whom had positive tests. CONCLUSIONS: Culprit drugs are frequently antibiotics and antiepileptic drugs, and onset is often less than 2 weeks after treatment starts, especially with antibiotics. Treatment with topical corticosteroids appears to be sufficient in the least severe cases. Treatment by systemic corticosteroid therapy remains the reference treatment in case of severe organ damage.

Evaluation of Children with Psoriasis from the BiPe Cohort: Are Patients Using Biotherapies in Real Life Eligible for Phase III Clinical Studies?

BACKGROUND: Phase III clinical trials of biotherapies for childhood psoriasis are designed for a selected population, which can differ from real-life patients. OBJECTIVE: Our objective was to assess the proportion of children with psoriasis that received biotherapy in the biological treatments for pediatric psoriasis (BiPe) cohort that would be excluded from phase III clinical trials of these treatments. METHODS: Data concerning initiation of the first biotherapy from all patients included in the BiPe cohort were analyzed. Ineligibility was assessed after applying the exclusion criteria used in the principal phase III trials of etanercept, adalimumab, and ustekinumab for childhood psoriasis. RESULTS: Of the 134 patients included, 73 (54.5%) were ineligible for at least one randomized controlled trial based on one or more exclusion criteria. Amongst the 63 children treated with etanercept, 35 (55.5%) were ineligible: 22 because of the type of psoriasis, 12 because of concomitant treatment, and six because of psoriasis severity based on psoriasis assessment severity index (PASI) and physician global assessment (PGA) scores (PASI < 12 and PGA < 3). Amongst the 44 children treated with adalimumab, 32 (72.7%) were ineligible: 17 because of the clinical type of psoriasis, 12 because of psoriasis severity (PASI < 20 and PGA < 4), and seven because of concomitant treatment. Amongst the 27 children patients treated with ustekinumab, 12 (44.4%) were ineligible: eight because of psoriasis severity (PASI < 12 and PGA < 3), five because of the clinical type of psoriasis, and one because of concomitant treatment. Drug survival and the frequency of serious adverse events did not differ between eligible and ineligible patients. CONCLUSION: The majority of children treated with biotherapies in real-life practice differ from those in phase III trials, most commonly because of the clinical type of their psoriasis, the disease severity being lower than required and the use of prior or concomitant psoriasis treatment. Efficacy and safety results from phase III clinical trials in selected populations may not sufficiently reflect what is seen in real life, thus results from real-life cohort studies are necessary.

Large International Validation of ABSIS and PDAI Pemphigus Severity Scores.

The Pemphigus Disease Area Index (PDAI) and Autoimmune Bullous Skin Disorder Intensity-Score (ABSIS) scores have been proposed to provide an objective measure of pemphigus activity. These scores have been evaluated only on already treated patients mainly with mild to moderate activity. The objective was to assess the interrater reliability of ABSIS and PDAI scores and their correlation with other severity markers in a large international study. Consecutive patients with newly diagnosed pemphigus were enrolled in 31 centers. Severity scores were recorded during a 24-month period by the same two blinded investigators. Serum was collected at each visit for ELISA measurement of anti-desmoglein antibodies. The intraclass correlation coefficient (ICC) and Spearman rank correlation coefficient were calculated. A total of 116 patients with pemphigus vulgaris (n = 84) or pemphigus foliaceus (n = 32) were included. At baseline, the ABSIS and PDAI ICCs were 0.90 (95% confidence interval [CI] = 0.85-0.93), and 0.91(95% CI = 0.87-0.94), respectively. The ICCs for PDAI were higher in moderate and extensive pemphigus (ICC = 0.82, 95% CI = 0.63-0.92 and ICC = 0.80, 95% CI = 0.62-0.90, respectively) than in patients with intermediate (significant) extent (ICC = 0.50, 95% CI = 0.27-0.68). Conversely, the ICCs for ABSIS were lower in patients with moderate extent (ICC = 0.44, 95% CI = 0.004-0.74) than in those with intermediate or extensive forms, (ICC = 0.69, 95% CI = 0.51-0.81 and ICC = 0.75, 95% CI = 0.51-0.88, respectively). During patients' follow-up, the ICCs of both ABSIS and PDAI scores remained higher than 0.70. ABSIS and PDAI skin (r = 0.71 and r = 0.75) but not mucosal (r = 0.32 and r = 0.37) subscores were correlated with the evolution of anti-DSG1 and anti-DSG3 ELISA values, respectively. ABSIS and PDAI scores are robust tools to accurately assess pemphigus activity.

Pain and quality of life evaluation in patients with localized epidermolysis bullosa simplex.

BACKGROUND: A localized form of epidermolysis bullosa simplex (EBS-l) is considered one of the mildest forms of epidermolysis bullosa (EB), with blisters limited to the palms and soles. However, these lesions can be very painful. The aim of the study was to characterize pain in patients with EBS-l and evaluate its impact on quality of life (QoL). Patients were contacted via the Research Group of the French Society of Pediatric Dermatology and the association of EB patients (DEBRA France). One investigator used a standardized questionnaire that included validated scales for pain and QoL for a telephone interview. RESULTS: We included 57 patients (27 children). All patients had pain: the mean pain on a 10-mm visual analog scale was >5 for most adults (90%) and children ≥8 years old (94%) when blisters were present and for most adults (73%) and about half of the children ≥ age 8 (53%) during dressing changes. Similar results were found for younger patients. Overall, 75% of patients had neuropathic pain; for 55% of children and 73% of adults, the pain had a moderate to severe impact on QOL. Only seven patients used premedication before changing dressings and seven regularly used oral treatment for chronic pain. A total of 21% and 23% of patients used non-steroidal anti-inflammatory drugs and grade 2 analgesics, respectively. These treatments were not effective for neuropathic pain. Six patients tried 5% lidocaine plasters on their feet, with good efficacy. CONCLUSIONS: EBS-l patients have frequent and severe pain with neuropathic characteristics. This pain is undertreated and affects QoL.
