Treating Wounds With an Avascular Component With a Dermal Regenerative Template

Wounds : a Compendium of Clinical Research and Practice

Abstract

Partially avascular wounds pose a challenge to wound care surgeons. The authors reviewed the literature and institutional results on the use of a dermal regenerative template (DRT) over partially avascular wounds to quantify the ability of the DRT to vascularize over these wounds. A review of the literature was performed using Ovid MEDLINE, Google Scholar, and Cochrane Library. Patient demographics, comorbidities, wound types, surface area of avascular tissues, and skin graft take were analyzed. A retrospective review of institutional cases was conducted. A total of 32 articles met inclusion criteria. The retrospective review included 26 patients with partially avascular wounds reconstructed with the DRT. Seventeen patients experienced 100% graft take, 6 experienced partial take, and 3 suffered complete loss. The percent and absolute size of avascular surface area in the wound was significantly lower in cases of complete graft take compared with partial take and complete loss (1.9% and 2.7 cm2; 9.3% and 10.0 cm2; 18.0% and 9.3 cm2, respectively, P ⟨ .001). Chronic wound status (P ⟨ .001) was significantly associated with less graft take. This literature review and retrospective study confirm the DRT is a viable option to provid...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
