Epidermal stem cells maintain stemness via a biomimetic micro/nanofiber scaffold that promotes wound healing by activating the Notch signaling pathway.

Stem Cell Res Ther 2021 Jun 10;12(1):341. Epub 2021 Jun 10.

Department of Plastic Surgery, Tangdu Hospital, Airforce Military Medical University, Xi'an, 710038, China.

Background: Epidermal stem cells (EpSCs) play a vital role in wound healing and skin renewal. Although biomaterial scaffolds have been used for transplantation of EpSCs in wound healing, the ex vivo differentiation of EpSCs limits their application.

Methods: To inhibit the differentiation of EpSCs and maintain their stemness, we developed an electrospun polycaprolactone (PCL)+cellulose acetate (CA) micro/nanofiber for the culture and transplantation of EpSCs. Read More

Long term outcomes of the French ASTIS systemic sclerosis cohort using the global rank composite score.

Bone Marrow Transplant 2021 Jun 9. Epub 2021 Jun 9.

Unité de Médecine Interne: Maladies Auto-immunes et Pathologie Vasculaire (UF 04), Centre de Référence des Maladies auto-immunes systémiques Rares d'Ile-de-France MATHEC, AP-HP, Hôpital Saint-Louis, Paris, France.

Two randomised trials (ASTIS, SCOT) of Autologous Hematopoietic Stem Cell Transplantation (AHSCT) versus monthly Cyclophosphamide for severe Systemic Sclerosis (SSc) patients used similar inclusion criteria, but different primary endpoints: event-free-survival (EFS) at 24 months in ASTIS versus the global rank composite score (GRCS) at 54 months in SCOT. Here we analysed the French ASTIS cohort (n = 49) outcome using the same GRCS endpoint as reported in SCOT. All patients, randomised to AHSCT (n = 26) or Cyclophosphamide (n = 23), were evaluated for the non-parametric GRCS endpoint based on: death, EFS, forced vital capacity (FVC), Health Assessment Questionnaire Disability Index (HAQ-DI) and modified Rodnan skin score (mRSS) at 60 months.

A Case of Giant Congenital Melanocytic Nevus Treated with Combination Therapy of Autologous Mesh-skin Grafts and Cultured Epithelial Autografts.

Plast Reconstr Surg Glob Open 2021 Jun 7;9(6):e3613. Epub 2021 Jun 7.

Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Kyoto University, Sakyo-ku, Kyoto, Japan.

Surgical excision of a giant congenital melanocytic nevus (GCMN) results in a full-thickness skin defect that is usually difficult to reconstruct even with tissue expansion or skin grafting. Here, we report the first case of GCMN treated with a combination of cultured epithelial autografts (CEAs) and mesh-skin grafts to reconstruct a large skin defect after surgical excision. A 14-month-old girl had a GCMN occupying 20% of the total body surface area of her neck and back. Read More

Safety Profile and Predictors of Aesthetic Outcomes After Prepectoral Breast Reconstruction With Meshed Acellular Dermal Matrix.

Ann Plast Surg 2021 Jun;86(6S Suppl 5):S585-S592

From the Department of Plastic Surgery, University of Virginia Health System, Charlottesville, VA.

Introduction: Prepectoral acellular dermal matrix (ADM)-assisted breast reconstruction has demonstrated improved pain scores, faster return to full range of motion, and an appropriate postoperative safety profile when compared with cohorts with submuscular implant placement; however, there are limited data on aesthetic outcomes. Basic science biointegration research has previously demonstrated faster ADM incorporation with fenestrated compared with confluent ADM. We report the safety profile of anterior support meshed ADM prepectoral breast reconstruction and analyze predictive factors for aesthetic outcomes after gel implant placement. Read More

Adipose Grafting for Volume and Scar Release.

Ann Plast Surg 2021 Jun;86(6S Suppl 5):S487-S490

Division of Plastic and Reconstructive Surgery, Department of Surgery, University of Alabama at Birmingham, Birmingham, AL.

Abstract: Adipose fat grafting (AFG) is a popular technique used to add volume in the face, breasts, and other tissue deficient areas of the body. In terms of scar release, not only has fat provided additional soft tissue coverage but also the relief of pain in scars in those patients suffering from disease processes, such as complex regional pain syndrome with steroid-induced atrophy, burn scars, morphea, and lupus. The purpose of this article is to demonstrate the senior author's technique and outcomes of using AFG in the face and body for treating volume deficiency, atrophic scarring, and deformities.

Anti-COVID-19 measurements for hidradenitis suppurativa patients.

Exp Dermatol 2021 06;30 Suppl 1:18-22

European Hidradenitis Suppurativa Foundation e.V., Dessau, Germany.

The reported incidence of COVID-19 among cohorts of patients with inflammatory bowel and skin diseases under treatment with biologicals is low. Treatment may further modify disease severity as some biological modifiers, such as anakinra, are also proposed for the management of COVID-19 patients potentially providing HS patients with an advantage. The above preliminary evidence suggests that hidradenitis suppurativa (HS) does probably not provide an increased susceptibility for COVID-19 and that any susceptibility is unlikely to be modified negatively by treatment with biologicals.

Target molecules for future hidradenitis suppurativa treatment.

Exp Dermatol 2021 Jun;30 Suppl 1:8-17

European Hidradenitis Suppurativa Foundation e.V., Dessau, Germany.

The registration of the tumour necrosis factor-α inhibitor adalimumab in 2015 was a major step forward in the treatment of hidradenitis suppurativa/acne inversa (HS). However, it soon became evident that the effectiveness of adalimumab in daily practice was highly variable. A significant unmet medical need of HS patients remained, and the search for novel therapeutic targets was intensified. Read More
