Improving Pressure Ulcer Reconstruction: Our Protocol and the COP (Cone of Pressure) Flap.

Background: Surgical treatment of pressure ulcers is challenging for high recurrence rates. Deepithelialized flaps have been used previously with the aim to eliminate shearing forces and the cone of pressure (COP) effect. The goal of this study is to adopt a standardized protocol and evaluate if 2 different flap techniques affect outcomes.

Investigation of the growth and metastasis of malignant melanoma in a murine model: the role of supplemental vitamin A.

Vitamin A possesses both wound-healing and antitumor actions. Vitamin A-induced fibroplasia results in subsequent increased collagen production and deposition. This effect of vitamin A has been shown to result in the production of collagenous capsules around several murine breast and lung tumor systems.

The fetal cleft palate: III. Ultrastructural and functional analysis of palatal development following in utero repair of the congenital model.

The role of fetal surgery in the management of congenital anomalies and intrauterine abnormalities is appropriately restricted on the basis of feasibility and risk-to-benefit analyses of intrauterine intervention. Recently, the authors demonstrated that in utero cleft palate repair of the congenital caprine model is technically feasible and results in scarless healing of the mucoperiosteum and velum, with subsequent development of a potentially functional bilaminar palate with distinct oral and nasal mucosal layers, following single-layer repair of the fetal mucoperiosteal flaps. A slight indentation at the site of repair was the only remaining evidence of a cleft.
