Background: Biosynthetic porcine type I collagen dressing is useful to close ulcers and secondary intention healing of surgical cancer wounds.
Objective: To identify factors associated with the healing time of such wounds.
Methods: We conducted a retrospective observational study of patients on oncological dermatological surgery in a cancer center. Healing time was studied based on age, sex, personal history of comorbidities, usual medication, anatomical location, type of surgery performed and size of the defect. Statistical analysis was performed using the ANOVA test and logistic regression.
Results: A total of 306 patients were included with a median age of 73 years (62.4%, men). The statistically significantly characteristics associated with a healing time ≤ 66 days were location-auricle, nose, inner canthus, hand, retroauricular region and nail bed-use of the Mohs technique and defect sizes ≤ 5.28 cm.
Limitations: This is a retrospective study from a single center.
Conclusion: The use of biosynthetic porcine type I collagen dressings for the definitive closure of dermatological surgical cancer wounds seems particularly suitable for small defects of the inner canthus of the eye, hand, auricle, nose, forehead, retroauricular region, and nail bed.

Background: Extracellular matrix (ECM) proteins play a crucial role in regulating the biological properties of adherent cells. For cryopreserved fibroblasts, a favourable ECM environment can help restore their natural morphology and function more rapidly, minimizing post-thaw stress responses.
Methods And Results: This study explored the functional responses of cryopreserved enriched caprine adult dermal fibroblast (cadFibroblast) cells to structural [collagen-IV and rat tail collagen (RTC)] and adhesion ECM proteins (laminin, fibronectin, and vitronectin) under in vitro culture conditions.

Rotator cuff injury (RCI), characterized by shoulder pain and restricted mobility, represents a subset of tendon-bone insertion injuries (TBI). In the majority of cases, surgical reconstruction of the affected tendons or ligaments is required to address the damage. However, numerous clinical failures have underscored the suboptimal outcomes associated with such procedures.

Diabetic foot wounds (DFW) are notoriously difficult to treat owing to poor vascularity, delayed healing and higher rates of infection. Human-derived acellular dermal matrices (ADM) have been used in DFW treatment, utilizing a matrix scaffold for new tissue generation. We investigate the efficacy of a micronized injectable human-derived ADM in the treatment of DFW.
