Pyoderma gangrenosum (PG) is a rare disease characterized by ulcerative cutaneous lesions that can occur postoperatively and is often associated with autoimmune disorders. PG is diagnosed by excluding other conditions that can cause ulcerations, such as infections, which may also result in immunosuppressive treatment delays and suboptimal wound care. Operative debridement of wounds has traditionally been avoided in the acute setting secondary to pathergy.

Hypergranulation is the abnormal accumulation of granulation tissue in a wound and is commonly seen in burns. It impairs wound healing and can predispose patients to infection. There is no gold standard treatment for hypergranulation tissue, but some options include surgical debridement, chemical cautery with silver nitrate, and topical steroids.

Article Synopsis
  • Measuring skin color for medical research typically requires expensive in-person equipment, but the Skin Analyzer application provides a more accessible and efficient alternative using photographs.
  • This desktop app converts digital images to L*a*b color space to calculate an individual typology angle, correlating with Fitzpatrick skin types, achieving an accuracy of 80%.
  • The app demonstrates high interrater reliability with a Krippendorff alpha of 0.84, making it a reliable tool for objectively assessing skin types, particularly for retrospective studies where traditional methods are not feasible.

Acute and chronic wounds involving deeper layers of the skin are often not adequately healed by dressings alone and require therapies such as skin grafting, skin substitutes, or growth factors. Here we report the development of an autologous heterogeneous skin construct (AHSC) that aids wound closure. AHSC is manufactured from a piece of healthy full-thickness skin.
