Abstract
BACKGROUND The objective was to provide international recommendations on anti-aging dermocosmetics for clinical practice starting with essential ingredients for protection and repair before working up to advanced products for specific concerns. Methods: Seven international experts reviewed 8 hypothetical case scenarios covering different ages, skin issues (eg, sensitivity, acne, melasma), and exposure to exposome factors for both sexes and all Fitzpatrick skin types (FST). The RAND/UCLA appropriateness method was used to obtain consensus. Seventeen key ingredients were rated on a scale from 1 (totally inappropriate) to 9 (totally appropriate). Statistical analysis, 2 meetings, and email discussions refined the recommendations. RESULTS High-factor broad-spectrum sunscreen (ie, protects against ultraviolet [UV] A and B rays), niacinamide, and other topical antioxidants were recommended for all scenarios. Further discussions were required for other ingredients. Tinted sunscreen/iron oxide were recommended for all FST, although compliance may be sub-optimal for darker skin phototypes (IV-VI), if not cosmetically acceptable. Combining a facial foundation with broad-spectrum sunscreen was recommended for darker phototypes to obtain visible light protection closely matching diverse color tones. Retinols were not recommended as a first-line treatment for sensitive skin, especially FST V and VI, due to the risk of irritation. After ablative laser treatment, alpha hydroxy acids should be avoided or used with caution in FST IV to VI due to the risk of post-inflammatory hyperpigmentation. CONCLUSION We describe a simple, practical tool for use in daily dermatology consultations for providing recommendations on anti-aging dermocosmetics to cover diverse and inclusive populations of patients, addressing all skin types and international needs.

Abstract
BACKGROUND Skin aging is a gradual cumulative process that may be accelerated by various exposome factors. AIMS To investigate associations between exposome factors and facial skin aging in 11 locations in Argentina. PATIENTS/METHODS An observational, cross-sectional study with assessments by exposome questionnaire, Glogau photoaging classification from I to IV, AI-based algorithm analysis of 7 skin aging signs, and SCINEXA score. RESULTS Of 1346 participants, most were women (82%), aged 31-50 years (62%), of skin phototype III (52%), and living in urban areas (94%). The Glogau skin age was higher than the chronological age for 28% of overall participants, 36% of men, and 45% of participants from Ciudad de Buenos Aires versus 12% from Jujuy (p < 0.001). Being male (OR = 1.59; 95% CI 1.18-2.13), exposed to agrochemicals (OR = 1.59: 95% CI 1.01-2.51), of lower socioeconomic levels (OR = 2.06; 95% CI 1.32-3.21) and doing outdoor physical activity (OR = 1.33; 95% CI 1.00-1.76) increased the risk for premature aging. Odds decreased with high daily intake of water (OR = 0.76; 95% CI 0.59-0.97), daily dermocosmetic use (moisturizers [OR = 0.72; 95% CI 0.55-0.94], cleansers [OR = 0.53; CI 95% 0.42-0.67], retinoids [OR = 0.61; 95% CI 0.39-0.95]), and antiaging treatments (OR = 0.74; 95% CI 0.57-0.97). CONCLUSIONS Some exposome factors increased the risk for premature skin aging (physical outdoor activity, exposure to agrochemicals), while others were protective factors (high water intake, antiaging treatments, use of dermocosmetics). Locations with higher pollution levels had more premature skin aging.

Abstract
INTRODUCTION Scalp psoriasis frequently goes with other disease location and may lead to a significant burden and impairment of quality of life (QoL). Adherence to local treatments is a frequent problem. A keratolytic and hydrating shampoo containing 2% salicylic acid, 5% urea, and 1% glycerin (active shampoo) has been developed for psoriasis-prone scalp. OBJECTIVE To assess the efficacy and tolerability of an active shampoo in subjects with mild to moderate scalp psoriasis. MATERIALS AND METHODS A single-center, randomized, double-blind, vehicle-controlled study was conducted on 67 adults with mild to moderate psoriasis. The active shampoo or its vehicle were applied daily for 14 days and 3 times/week for another 14 days. Assessments included the Psoriasis Scalp Severity Index (PSSI), Investigator Global Assessment (IGA), calculated total surface affected hair, scalp greasiness, irritation, and assessed scalp dermatitis-specific quality-of-life issues using SCALPDEX and product acceptability. RESULTS The active shampoo significantly (p < 0.05) reduced the PSSI by 39.0%, 37.2%, 63.0%, and 69.0% immediately after washing compared to a 22.8%, 5.5%, 19.6%, and 13.0% with the vehicle at Days 1, 8, 15, and 30, respectively. SCALPDEX items, IGA, and irritation significantly (p < 0.05) reduced with the active shampoo. Hair and scalp greasiness improved continuously with both products until Day 21. Subject-reported symptom scores paralleled the positive evolution of clinical signs. The active shampoo was well tolerated, subjects were highly satisfied and had an improved QoL. CONCLUSION The active shampoo significantly improved clinical signs, symptoms, and QoL of mild-to-moderate scalp psoriasis compared to the vehicle. It was very well tolerated and highly appreciated by the subjects.

Abstract
INTRODUCTION The distinction between epidermal necrolysis [EN; including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) and overlap syndrome] and erythema multiforme major (EMM) in children is confusing. We aimed to better describe and compare these entities. MATERIALS AND METHODS This French retrospective multicentre study included children ≤18 years old referred for EN or EMM between 1 January 2008 and 1 March 2019. According to pictures, children were reclassified into TEN/overlap, SJS or EMM/unclassified (SJS/EMM) groups and compared for epidemiological and clinical data, triggers, histology and follow-up. RESULTS We included 62 children [43 boys, median age 10 years (range 3-18)]: 16 with TEN/overlap, 11 SJS and 35 EMM. The main aetiologies were drugs in EN and infections (especially Mycoplasma pneumoniae) in EMM (P < 0.001), but 35% of cases remained idiopathic (TEN/overlap, 47%; SJS, 24%; EMM, 34%). The typical target lesions predominated in EMM (P < 0.001), the trunk was more often affected in EN (P < 0.001), and the body surface area involved was more extensive in EN (P < 0.001). Mucosal involvement did not differ between the groups. Two patients with idiopathic TEN died. Histology of EMM and EN showed similar features. The recurrence rate was 42% with EMM, 7% with TEN/overlap and 0 with SJS (P < 0.001). Sequelae occurred in 75% of EN but involved 55% of EMM. CONCLUSION Clinical features of EN and EMM appeared well demarcated, with few overlapping cases. Idiopathic forms were frequent, especially for EN, meaning that a wide and thorough infectious screening, repeated if needed, is indicated for all paediatric cases of EN/EMM without any trigger drug. We propose a comprehensive panel of investigations which could be a standard work-up in such situation. Sequelae affected both EN and EMM.

Abstract
INTRODUCTION Severe epidermolysis bullosa simplex (EBS sev) is a rare genodermatosis characterized by congenital generalized blistering and mucosal involvement. Increased needs and decreased intake quickly lead to nutritional imbalance. Enteral nutrition support is proposed, but classical nasogastric tubes are not well tolerated in these patients and gastrostomy is preferred. OBJECTIVE AND METHODS To report the experience with EBS sev in neonatal units of French reference centers for gastrostomy. In this retrospective multicentric study, we included all patients with EBS sev who had gastrostomy placement before age 9 months during neonatal care hospitalization. RESULTS Nine infants (5 males/4 females) with severe skin and mucosal involvement were included. A gastrostomy was decided, at an early age (mean 3.7 months, range 1.4 to 8 months) in infants with mean weight 4426 g (range 3500 to 6000 g). Techniques used were endoscopy with the pull technique for 5 infants and surgery under general anesthesia for 4. Main complications were local but resolved after treatment. All infants gained weight after gastrostomy. The mean withdrawal time (n = 7) for the gastrostomy was 35.8 months (range 10.5 months to 6.5 years). Seven children had persistent oral disorders. CONCLUSIONS Gastrostomy in infants with EBS sev can be necessary in neonatal intensive care units. Both surgical and endoscopic pull techniques seem efficient, with good tolerance.

Abstract
Albinism is a worldwide genetic disorder caused by mutations in at least 20 genes, identified to date, that affect melanin production or transport in the skin, hair and eyes. Patients present with variable degrees of diffuse muco-cutaneous and adnexal hypopigmentation, as well as ocular features including nystagmus, misrouting of optic nerves and foveal hypoplasia. Less often, albinism is associated with blood, immunological, pulmonary, digestive and/or neurological anomalies. Clinical and molecular characterizations are essential in preventing potential complications. Disease-causing mutations remain unknown for about 25% of patients with albinism. These guidelines have been developed for the diagnosis and management of syndromic and non-syndromic forms of albinism, based on a systematic review of the scientific literature. These guidelines comprise clinical and molecular characterization, diagnosis, therapeutic approach and management.

Abstract
Inherited epidermolysis bullosa defines a heterogeneous group of genodermatoses characterized by skin and/or mucosa fragility resulting in blistering. The junctional variant (JEB) is associated with mutations affecting the genes expressing the components of the dermo-epidermal junction (DEJ) [1-2]. We report 34 JEB patients with COL17A1 genetic mutations diagnosed in our Center between 1993 and 2019. Medical and biological records were collected with a standardized questionnaire.

Abstract
BACKGROUND Netherton syndrome (NS) is a rare disease caused by SPINK5 mutations, featuring variable skin and hair involvement and, in many cases, allergic manifestations with a risk of lethality, particularly in infants. The clinical management of NS is challenging. OBJECTIVES To analyse the clinical manifestations of a cohort of infants with NS managed in a reference centre and to draw up recommendations for management. METHODS We conducted a monocentric analysis of patients with NS. The inclusion criteria were management in our reference centre, a histologically or molecularly confirmed diagnosis of NS and available epidemiological, clinical and laboratory data. RESULTS A total of 43 patients with NS were included. Hypernatraemia was reported in 23 cases (54%) and associated with a greater likelihood of enteral and/or parenteral nutritional support (P < 0.001). Moreover, hypernatraemia was more frequent in patients with skin manifestations at birth (P = 0.026) and in patients bearing the c.153delT mutation in SPINK5 exon 3 (P = 0.014). The need for enteral and/or parenteral nutritional support was associated with a history of hypernatraemic dehydration (P < 0.001). Several unexpected extracutaneous complications were recorded, and new mutations were reported. The death rate (9% overall) was higher among the subset of patients bearing the c.153delT deletion. CONCLUSIONS Our data emphasize that neonatal NS is a severe and sometimes lethal multisystem disorder. Patients have a high risk of variable metabolic anomalies (i.e. lethal hypernatraemia) and therefore have major nutritional needs. Cases of NS associated with c.153delT are particularly severe. Unexpected clinical manifestations broadened the phenotypic spectrum of NS. We provide recommendations on the management of the life-threatening manifestations of NS in neonates based on our multidisciplinary experience.

Abstract
BACKGROUND Paediatric cutaneous granuloma with primary immunodeficiency (PID) is a rare condition. The physiopathology is unclear, and treatment is challenging. We report on 17 paediatric cases and review the literature. OBJECTIVES To make dermatologists and dermatopathologists aware of the diagnostic value of skin granulomas in paediatric PID. METHODS We collected data on 17 patients with cutaneous granulomas and PID registered with us and also reviewed 33 cases from the literature. RESULTS Cutaneous granuloma was the presenting feature of the PID in 15 of the 50 collated cases. The lesions presented as red-brownish nodules and infiltrated ulcerative plaques, predominantly on the face and limbs. Scleroderma-like infiltration on a single limb was observed in 10% of the cases. The associated PID was ataxia-telangiectasia (52%), combined immunodeficiency (24%), cartilage-hair hypoplasia (6%) and other subtypes (18%). The granulomas were mostly sarcoidal, tuberculoid, palisaded or undefined subtypes. In some patients, several different histopathologic granulomatous patterns were found in the same biopsy. Some granulomas were associated with the presence of a vaccine strain of rubella virus. CONCLUSION Cutaneous granulomas associated with a PID have a variable clinical presentation. A PID can be suspected when crusty, brownish lesions are found on the face or limbs. The concomitant presence of several histological subtypes in a single patient is suggestive of a PID.

Abstract
BACKGROUND Herein we present a case of palmoplantar keratoderma (PPK) in a young adopted girl of Chinese origin living in France. OBSERVATION The patient, aged six years, had presented transgressive PPK since birth, as well as erythema progressing in congestive inflammatory episodes, palmoplantar hyperhidrosis and progressive characteristics (moderate hyperkeratosis in areas of rubbing other than the palms and soles, namely the elbows and knees). Histopathological examination of a skin biopsy revealed a thick epidermis with lengthening and thickening of crests. The epithelium displayed a thick granular layer. Electron microscopy showed hyperorthokeratosis with hypergranulosis and loss of lamellar structure of the keratinosomes, as well as cleavage between corneocytes. Molecular studies showed the presence of two composite heterozygous mutations of the SERPINB7 gene, enabling a diagnosis of Nagashima-type PPK (NPPK) to be made. DISCUSSION NPPK is an autosomal recessive disease caused by a mutation in the SERPINB7, a member of the superfamily of serine protease inhibitors. It was described by Nagashima in 1977 with molecular characterisation by Kubo following in 2013. It is the most widespread form of PPK in Asia (with a prevalence of 1.2/10,000 in Japan and 3.1/10,000 in China). It is distinguished from the other PPKs in terms of transgressive soft hyperkeratosis, inflammatory episodes and hyperhidrosis, as well as by its non-progressive nature. In the present case, while the clinical presentation was characteristic, diagnosis was only made thanks to sequencing of a panel of over 50 genes responsible for PPK. The disease is effectively little-known in Europe. This study highlights the increasing importance of diagnostic investigation methods involving the use of gene panels.

Sixteen novel mutations in PNPLA1 in patients with autosomal recessive congenital ichthyosis reveal the importance of an extended patatin domain in PNPLA1 that is essential for proper human skin barrier function.

Abstract
BACKGROUND Autosomal recessive congenital ichthyosis (ARCI) is a genetically heterogeneous group of rare Mendelian skin disorders characterized by cornification and differentiation defects of keratinocytes. Mutations in nine genes including PNPLA1 are known to cause nonsyndromic forms of ARCI. To date, only 10 distinct pathogenic mutations in PNPLA1 have been reported. OBJECTIVES To identify new causative PNPLA1 mutations. METHODS We screened genetically unresolved cases, including our ARCI collection, comprising more than 700 families. Screening for mutations was performed either by direct Sanger sequencing or in combination with a multigene panel, followed by sequence and mutation analysis. RESULTS Here we report on 16 novel mutations present in patients from 17 families. While all previously reported mutations and most of our novel mutations are located within the core patatin domain, we report five novel PNPLA1 mutations that are downstream of this domain. Thus, as recently described for PNPLA2, we hypothesize that a region larger than the core domain is required for full enzymatic activity of PNPLA1 in human skin barrier formation. CONCLUSIONS We estimate the frequency of PNPLA1 mutations among patients with ARCI to be around 3%. Most of our patients were born as collodion babies and showed a relatively mild ichthyosis phenotype. In four unrelated patients we observed a cyclic scaling course, which seems to be a potential phenotypic variation in a small percentage of patients with PNPLA1 mutations. The variability of the clinical manifestations and the lack of typical clinical features are specific for patients with PNPLA1 mutations, and emphasize the importance of DNA sequencing for differential diagnosis of ARCIs.

Live rubella virus vaccine long-term persistence as an antigenic trigger of cutaneous granulomas in patients with primary immunodeficiency. Clin Microbiol Infect 2014; 20:O656-63.

Abstract
Granulomas may develop as a response to a local antigenic trigger, leading to the activation of macrophages and T-lymphocytes. Primary immunodeficiency (PID) is associated with the development of extensive cutaneous granulomas, whose aetiology remains unknown. We performed high-throughput sequencing of the transcriptome of cutaneous granuloma lesions on two consecutive index cases, and RT-PCR in a third consecutive patient. The RA27/3 vaccine strain of rubella virus-the core component of a universally used paediatric vaccine-was present in the cutaneous granuloma of these three consecutive PID patients. Controls included the healthy skin of two patients, non-granulomatous cutaneous lesions of patients with immunodeficiency, and skin biopsy samples of healthy individuals, and were negative. Expression of viral antigens was confirmed by immunofluorescence. Persistence of the rubella vaccine virus was also demonstrated in granuloma lesions sampled 4-5 years earlier. The persistence of the rubella virus vaccine strain in all three consecutive cutaneous granuloma patients with PID strongly suggests a causal relationship between rubella virus and granuloma in this setting.

Abstract
AIMS To better define the characteristics of Spitz naevus (SN) in children, to determine whether it was clinically diagnosed and to examine the differential diagnoses made according to age. In addition, to determine whether atypical spitzoid tumors (AST) have a different presentation from other forms of SN. PATIENTS AND METHODS A two-centre retrospective survey was made of histopathological reports written over a 4-year period in children aged under 18 years. The inclusion criterion was unequivocal diagnosis of SN or AST. Age, gender, site, size, course, excision methods, presumptive clinical diagnoses and the percentage of correct diagnosis were analyzed for four distinct age groups. RESULTS One hundred and ninety-six patients were included, 186 with SN and 10 with AST. Mean age at diagnosis of SN was 9 years. Female predominance and predilection for the lower limbs were seen for all age groups. Facial involvement was less frequent and chiefly affected children aged under 11 years. Most SN lesions measured between 4 and 8mm. They were often confused with either pyogenic granuloma or juvenile xanthogranuloma, mainly before the age of 11 years. An accurate diagnosis was made in 29% of cases, chiefly in the 0 to 5 year-old age group. No cases of AST were clinically recognized, but it was diagnosed occasionally on histological grounds for very small tumours and in very young children. CONCLUSION Clinical diagnosis of SN is not always straightforward and in this study, AST exhibited no special features allowing it to be distinguished from SN. These results underline the need for caution in the event of SN in children, regardless of age or lesion size.
