Retronychia is an uncommonly reported condition among the category of nail pathologies. It often presents mimicking similar nail disorders, such as onychocryptosis, onychomycosis, and paronychia. This pathologic condition has recently seen an increased presence in the literature, mainly in the form of case studies. Literature on retronychia was collected using PubMed, the US National Library of Medicine, the National Institutes of Health's online database, life science journals, and online books. References cited by these articles were also reviewed for additional relevant publications. Reviews, case studies, and retrospective articles were compiled and analyzed for commonalities in cause, patient demographics, clinical signs, and treatment. Retronychia may be more common than previously suggested. Proper knowledge and education of this pathologic nail condition is important to health-care professionals to achieve early and correct diagnosis.
Studies have been conducted to evaluate the efficacy of dehydrated human amnion chorion membrane (dHACM) in treating recalcitrant diabetic foot ulcers. A literature search was performed to review the data collected from the use of dHACM allografts. Two products were explicitly named in these publications, EpiFix and AmnioBand Membrane. Relevant results included the healing rate, number of wounds healed, and number of grafts used. Data had supported the potential of lowering the overall cost to manage a wound despite a relatively higher cost per dressing. However, discrepancy was observed in the rate of healing between several of the studies. Nonetheless, dHACM had demonstrated improvement in healing of recalcitrant diabetic foot ulcers compared to standard of care alone. These results provide grounds for more inclusive research on dHACM in the future.
