Abstract
Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with a multifactorial aetiology that involves a strict interplay between genetic factors, immune dysregulation and lifestyle. Familial forms represent around 40% of total HS cases and show an autosomal dominant mode of inheritance of the disease. In this study, we conducted a whole-exome sequence analysis on an Italian family of 4 members encompassing a vertical transmission of HS. Focusing on rare damaging variants, we identified a rare insertion of one nucleotide (c.225dupA:p.A76Sfs*21) in the DCD gene encoding for the antimicrobial peptide dermcidin (DCD) that was shared by the proband, his affected father and his 11-years old daughter. Since several transcriptome studies have shown a significantly decreased expression of DCD in HS skin, we hypothesised that the identified frameshift insertion was a loss-of-function mutation that might be associated with HS susceptibility in this family. We thus confirmed by mass spectrometry that DCD levels were diminished in the affected members and showed that the antimicrobial activity of a synthetic DCD peptide resulting from the frameshift mutation was impaired. In order to define the consequences related to a decrease in DCD activity, skin microbiome analyses of different body sites were performed by comparing DCD mutant and wild type samples, and results highlighted significant differences between the groins of mutated and wild type groups. Starting from genetic analysis conducted on an HS family, our findings showed, confirming previous transcriptome results, the potential role of the antimicrobial DCD peptide as an actor playing a crucial part in the etio-pathogenesis of HS and in the maintenance of the skin's physiological microbiome composition; so, we can hypothesise that DCD could be used as a novel target for personalised therapeutic approach.

Abstract
Importance Hidradenitis suppurativa (HS) in pediatric patients has been understudied. Increased awareness and recognition of HS prevalence in children demand efforts to better understand this condition. Objective To describe the demographics, clinical features, treatment, associated comorbidities, and outcomes in a large cohort of pediatric patients with HS. Design, Setting, and Participants International, multicenter, retrospective medical record review of pediatric patients (aged 1-18 years) with a clinical diagnosis of HS carried out in 10 dermatology clinics across the US, Canada, Israel, Australia, and Italy from January 1996 to January 2017. Main Outcomes and Measures Patient demographics, clinical features, severity, associated comorbidities, and treatments in pediatric patients with HS. Results This cross-sectional study included 481 patients diagnosed with HS. Overall, 386 (80%) were girls. The mean (SD) age of disease onset was 12.5 (2.9) years, and the mean (SD) age at diagnosis was 14.4 (3.5) years. Family history of HS was present in 111 of 271 (41%) patients. First signs/symptoms reported at disease onset were cyst/abscess in 229 of 481 (48%), pain/tenderness in 118 of 481 (25%), and papules/pustules in 117 of 481 (24%). At initial dermatologic assessment, 233 of 481 (48%) patients already had evidence of skin scarring. Disease severity (Hurley staging) was documented in 288 of 481 (60%) patients (47% stage 1, 45% stage 2 and 8% stage 3). Comorbid conditions were reported in 406 of 481 (85%) patients, the most common being obesity (263/406 [65%]) and acne vulgaris (118/406 [29%]). Complications occurred in 378 of 481 (79%) patients, the most common of which were scars or contractures (301/378 [80%]). Conclusions and Relevance The findings of this study indicate that there is a gap in recognizing and diagnosing pediatric HS. Pediatric patients with HS are likely to present with other comorbidities. Prospective observational and interventional studies are needed to better understand clinical course and optimal treatments for pediatric HS.

Abstract
Hidradenitis suppurativa is a chronic immune mediated disease of universal
distribution that causes great damage to the quality of life of the affected
individual, whose prevalence is estimated at 0.41% in the Brazilian population.
The objective of this work was update on physiopathogenesis, diagnosis and
classification of hidradenitis suppurativa and to establish therapeutic
recommendations in the Brazilian reality. It was organized as a work group
composed of eight dermatologists from several institutions of the country with
experience in the treatment of hidradenitis suppurativa and carried out review
on the topic. Recommendations were elaborated and voted by modified Delphi
system and statistical analysis of the results was performed. The Brazilian
consensus on the clinical approach of hidradenitis suppurativa had the support
of the Brazilian Society of Dermatology.

Abstract
Background/Aims: Hidradenitis suppurativa (HS) is a chronic inflammatory and destructive skin disorder. Early diagnosis and treatment are critical to stop its progression. Data concerning adolescent-onset HS are scarce. The aims of this study are to describe the prevalence of adolescent-onset HS and to explore potential risk factors and the disease features of these patients. Patients and Methods: A cross-sectional study including 134 patients was performed. Results: Adolescent-onset HS occurred in 51.5% (69/134) of patients. Adolescent-onset HS was associated with female sex, positive family history, presence of pilonidal sinus, acne conglobata, longer disease duration and a worse perception of disease severity. Conclusion: Adolescent-onset HS might be more frequent than previously reported. Female sex, positive family history and the presence of elements of the follicular occlusion tetrad identify individuals with a higher risk of early onset. These patients experience a longer disease duration and perceive their disease as severer.

Abstract
Hidradenitis suppurativa (HS) can affect children, and ultrasound has been proven to be useful in diagnosis and staging. The sonographic characteristics of HS in children have not been reported. We studied color Doppler ultrasound images of children (≤15 years old; n = 12) with clinically and sonographically positive criteria for HS. Sonographic scoring of hidradenitis suppurativa (SOS-HS) was used to stage the cases sonographically. Subclinical pseudocysts were found in 92% of the cases, fluid collections in 83%, and fistulous tracts in 58%. Retained hair tracts in the fluid collections and fistulous tracts were present in 100% of patients; 67% of cases were SOS-HS stage II. In 92% of cases, management was modified after the ultrasound examination. In conclusion, ultrasound can be a reliable and safe imaging tool to support diagnosis and staging and may help in the noninvasive monitoring of treatment in children.
