AI Article Synopsis

  • The study investigates how miR-590-3p affects the survival of skin flaps through adipose-derived stem cells (ADSCs) in a mouse model.
  • ADSCs transplantation significantly improved skin flap recovery, while manipulating miR-590-3p levels altered the expression of key proteins associated with flap survival.
  • Findings suggest that targeting the miR-590-3p/VEGFA pathway in ADSCs could be a promising strategy for enhancing skin flap viability in surgical procedures.

Article Abstract

Introduction: Partial necrosis of skin flaps is still a substantial problem in plastic and reconstructive surgery. In this study, the role of miR-590-3p in adipose-derived stem cells (ADSCs) transplantation in improving the survival of skin flap in a mouse model was delved into.

Method: An abdominal perforator flap model was established in mice. The histopathological examination of mice skin tissues after ADSCs transplantation was implemented using Hematoxylin & eosin (H&E) staining. Immunohistochemistry (IHC) or immunofluorescence (IF) staining was utilized to assess the PCNA or CD31 levels. The concentrations of VEGFA in the culture medium were quantified using a VEGFA ELISA kit.

Result: The damage of tissue in the skin flap was dramatically relieved by ADSCs transplantation. MiR-590-3p overexpression notably suppressed, while miR-590-3p knockdown facilitated skin flap survival by regulating PCNA, VCAM-1, and VEGFA levels. MiR-590-3p targeted VEGFA to regulate its expression. The knockdown of VEGFA significantly inhibited, while overexpression of VEGFA notably promoted the survival of skin flap.

Conclusion: ADSCs transplantation promotes skin flap survival by boosting angiogenesis. The miR-590-3p/VEGFA axis modulates skin flap angiogenesis and survival in ADSCs. These results reveal that interfering with miR-590-3p in ADSCs could potentially be a novel therapeutic target for the improvement of skin flap survival.

Reconstruction of the Severe Cervical Scar Contracture Using a Combination of the Pre-expanded Bipedicled Forehead Flap and Lower Trapezius Musculocutaneous Flap.

J Craniofac Surg

January 2025

Department of Plastic and Reconstructive Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, Peking Union Medical College, Shijingshan District, Beijing, China.

Reconstructing severe cervical scar contractures (SCSC) remains a considerable challenge. This study presents a novel approach to SCSC reconstruction using a combination of pre-expanded bipedicled forehead and lower trapezius musculocutaneous flaps. A retrospective analysis was conducted on 25 patients who underwent this procedure between April 2004 and July 2020.

High-velocity traumatic amputations of the proximal upper extremity are devastating to the patient and represent an extreme surgical challenge to the treatment team. The hand surgeon must simultaneously battle devascularization with timely microvascular anastomosis, gross contamination with meticulous debridement, and amputation with stable fixation. In restoring a functional extremity, many of these goals are in contention with each other.

Importance: Surgery is frequently required for hidradenitis suppurativa (HS) treatment, but the impact of common comorbidities such as obesity, diabetes, and smoking on outcomes has been sparsely studied.

Observations: A total of 12 studies met final inclusion criteria for investigating complication rates associated with at least 1 comorbidity. Complication rates were associated with obesity in 3 of 10 studies.

January 2025

From the Department of Plastic and Reconstructive Surgery, Lahey Hospital and Medical Center, Burlington, MA.

Background: Defects of the nose present complex reconstructive challenges to the plastic surgeon. We present our experience with using the dorsal nasal flap (DNF) to provide a durable reconstruction even in sizable defects that would otherwise be considered necessitating a paramedian forehead flap.

Methods: We conducted a retrospective chart review of patients who underwent reconstruction by DNF following resection of skin cancers on the nose.
