Introduction: Clinical options are lacking for the management of chronic wounds or ulcers following failed debridement, skin grafting, or negative pressure wound therapy dressings.
Objective: This retrospective case series evaluated the efficacy of injectable AAM in the management and closure of chronic wounds.
Materials And Methods: Patients with nonhealing wounds of any etiology, anatomic location, and length of chronicity were included; those with multiple chronic wounds or prior skin grafting for wound repair were excluded. Data on location, etiology, chronicity, and number of AAM applications were collected for each wound. Patients were evaluated for possible complications related to wound healing and infection. Eleven patients (7 males, 4 females), each with 1 chronic wound, were recruited (average age, 65 years). Wound etiologies were postoperative (n = 7), traumatic (n = 2), and foot ulcer (n = 2). Average wound dimensions were 8.45 mm × 7.36 mm, and the average chronicity was 3.77 months. Ten patients received only 1 application of AAM, and 1 patient received 2 treatments 5 days apart. Average follow-up time was 6.6 weeks.
Results: Seven patients (63%) achieved wound closure, 4 of which (57%) healed within 1 week of application.
Conclusion: Most patients with chronic wounds treated with AAM experienced complete wound closure. AAM shows promising results for enhancing wound healing by providing scaffolding for cell growth.

Background: Congenital insensitivity to pain with anhidrosis is a rare but devastating hereditary disease. Congenital insensitivity to pain with anhidrosis is caused by a mutation in the neurotrophic receptor tyrosine kinase 1 gene (NRTK1). The condition is characterized by multiple injuries, recurrent infections, and mental retardation.

Background: A wound must progress through serial steps of healing to achieve structural and functional stability. This process is hampered in chronic wounds and wounds with delayed healing. Wound cover through skin grafting or a flap, or spontaneous healing through epithelization, requires healthy granulation tissue.

Background: The presence of heavy microbial colony formation, polymicrobial infection, and local altered pH contribute to the high rate of postoperative complications following surgical reconstruction of stage IV pressure injuries (PIs).
Purpose: The objective of this study was to determine the rate of bacteria-related postoperative complications following surgical reconstruction of stage IV PIs in which a pure hypochlorous acid (pHA) antimicrobially preserved wound cleaning solution was used.
Methods: This 1-year retrospective review evaluated the outcomes of patients who underwent surgical reconstructive treatment of chronic stage IV PI.

The pathophysiology of rotator cuff disease is complex, involving intrinsic and extrinsic factors that contribute to mechanical alterations, inflammation, apoptosis, and neovascularization. These changes result in structural and cellular disruptions, including inflammatory cell infiltration and collagen disorganization. Macrophages have recently gained attention as critical mediators of tissue repair and regeneration.

Delayed wound healing remains a major challenge in biomedical research, often leading to complications such as scarring, acute trauma, and chronic diseases. Effective wound management is crucial for enhancing treatment outcomes, preventing complications, and promoting tissue regeneration. In response to this need, a variety of polymeric biomaterials have been developed.
