The use of teledermatology abruptly expanded with the arrival of COVID-19. Here, we review recent studies regarding the efficacy, perception, and utilization of telemedicine in the pediatric population. To evaluate the current state of pediatric teledermatology. A literature search was performed using the terms “pediatric,” “teledermatology,” “dermatology,” “telemedicine” and “telehealth” in PubMed, Scopus, Embase, and Google Scholar. 44 articles published between 2008 and 2022 were included. Diagnostic concordance between pediatric teledermatologist and in-person dermatologist ranged from 70.1% to 89%. Conditions treated with pediatric teledermatology were similar to those treated in-person. The rate of in-person follow-up after an initial telemedicine appointment pre and postpandemic was 12% to 51.9% and 13.5% to 28.1%, respectively. Patient satisfaction with teledermatology was between 70% to 98% and provider satisfaction was approximately 95%. The integration of teledermatology can reduce missed appointments and wait times among pediatric patients. However, considerable technological challenges exist, particularly in underserved communities. Globally, teledermatology may expand access to care though limited literature exists regarding its use in pediatric populations. Telemedicine is effective for the diagnosis and treatment of many dermatological conditions in children, with high patient and provider satisfaction. Implementation of teledermatology can potentially increase access to care both locally and globally, but obstacles to engagement remain.

Follicular skin disorders, including hidradenitis suppurativa (HS), frequently coexist with systemic autoinflammatory diseases, such as inflammatory bowel disease (IBD) and its subtypes, Crohn’s disease and ulcerative colitis. Previous studies suggest that dysbiosis of the human gut microbiome may serve as a pathogenic link between HS and IBD. However, the role of the microbiome (gut, skin, and blood) in the context of IBD and various follicular disorders remains underexplored. Here, we performed a systematic review to investigate the relationship between follicular skin disorders, IBD, and the microbiome. Of the sixteen included studies, four evaluated the impact of diet on the microbiome in HS patients, highlighting a possible link between gut dysbiosis and yeast-exclusion diets. Ten studies explored bacterial colonization and HS severity with specific gut and skin microbiota, including Enterococcus and Veillonella. Two studies reported on immunological or serological biomarkers in HS patients with autoinflammatory disease, including IBD, and identified common markers including elevated cytokines and T-lymphocytes. Six studies investigated HS and IBD patients concurrently. Our systematic literature review highlights the complex interplay between the human microbiome, IBD, and follicular disorders with a particular focus on HS. The results indicate that dietary modifications hold promise as a therapeutic intervention to mitigate the burden of HS and IBD. Microbiota analyses and the identification of key serological biomarkers are crucial for a deeper understanding of the impact of dysbiosis in these conditions. Future research is needed to more thoroughly delineate the causal versus associative roles of dysbiosis in patients with both follicular disorders and IBD.

“COVID toes” is the colloquial name of chilblain-like lesions thought to be a sequela of COVID-19 infection. Over two years and approximately 300 publications later, this association remains controversial. Here, we summarize key clinical, serological, biological, histological, and immunological evidence that supports and rejects this relationship and discuss alternate theories underlying the pathogenesis of chilblain-like lesions.
