Filter by:This study will evaluate the use of free autologous dermal fat grafting (also called free dermal fat autografting) to treat complex craniofacial wounds that have failed standard treatment and to understand how well these grafts work to repair wounds long term. Patients who have undergone free autologous dermal fat grafting to treat complex craniofacial wounds less than 1 week ago will have photographs and small biopsies taken of the area that was grafted. Patients will be followed for 2 years to monitor the area that was grafted.
A comparison study was performed between Ligasure and Milligan morgan hemorrhoidectomy to find out the outcome between these two techniques in 3rd and 4th degree hemorrhoids.This advance vessel sealing device is used to seal the pedicle of the vessel and does not burn the surrounding tissues , so the outcome was monitored in terms of operative time, post operative pain pain, duration of wound healing in 3 weeks and return to normal activities
A randomized controlled clinical trial in two groups of supplementation with HMB and glutamine. Each group consist in 25 patients with bloody areas, one group will receive and intervention with HMB and Glutamine and the other will receive a placebo with calcium caseinate.
Subepithelial connective tissue graft (SCTG) has greater predictability for root coverage and causes minimal discomfort to patient. Although donor site heals with primary intention causing less scar tissue, in some different harvesting procedures primary flap closure may not be achieved due to nature of thick palatal tissues. Some potential complications may occur at donor site such as: necrosis of graft and palatal site, pain, excessive hemorrhage, protracted discomfort, donor site infection and in some cases donor site paresthesia. Platelet rich fibrin (PRF) is a platelet concentrate obtained by a simple procedure that does not require biochemical blood involvement.Based on the known biological effects of PRF, the aim of this study is to evaluate the PRF in the management of soft tissue donor sites in term of bleeding and pain sensation, and to observe the changes in tissue healing after a subepithelial connective tissue graft procedure at palatal donor site.
Evaluation of wound bed surface area containing clean, healthy viable tissue in full-thickness wounds.
TolaSure is a topical gel for the promotion of wound healing. This phase I study will assess the safety, tolerability and clinical effect of TolaSure when applied to skin wounds created by punch biopsy in healthy participants. A total of 26 healthy volunteers, males and females ages 18 years or older, will be enrolled. Subjects will monitored for safety and efficacy over the course of 2 weeks following daily topical administration of TolaSure.
The purpose of this study is to assess the perioperative use of Arnica Montana and the combined use of Arnica Montana and Bromelain in aiding the body's wound healing functions during the postoperative period after rhinoplasty. The secondary objective of the study is to determine if there is a reduction in postoperative edema when Arnica Montana and Bromelain are combined. Another secondary objective is to demonstrate increased patient satisfaction with the use of Arnica Montana and the combination Arnica Montana and Bromelain.
Backround: No data on the adjunctive effects of hyaluronic acid (HA) in a post-surgery, chlorhexidine (CHX) - based plaque control regimen are available. Also, contrasting evidence is available regarding the efficacy of CHX-based formulations containing anti-discoloration system (ADS). The aim of the present study was to evaluate the post-surgery gingival healing as well as plaque, gingival inflammation, and staining levels following the use of a 0.2% chlorhexidine (CHX) solution with or without anti-discoloration system (ADS) and 0.2% hyaluronic acid (HA). Methods: Patients undergoing flap surgery at sites with an intact or reduced but healthy periodontium participated in a parallel-arm RCT. After surgery, patients used the assigned mouthrinse (CHX+HA+ADS or CHX) for 21 days. At day 7 and 21, the Gingival Healing Index (GHI) was used to assess the quality of flap closure at the interdental papilla. Plaque index (PlI), Gingival Index (GI), Angulated bleeding score (AngBS), tooth and tongue staining were also assessed.
The skin plays a critical role in protection where it acts as a barrier from damage and pathogens between the external and internal environments. Wounds compromise its protective role by disrupting the function and the normal structure of the skin and the underlying soft tissue. As a response to injury wound healing occurs in order to rapidly restore the defect. This process involves activation of keratinocytes, fibroblasts, endothelial cells, macrophages, and platelets and consists of multiple phases including hemostasis, inflammation, migration and cellular proliferation, and maturation and remodeling. A simplified schematic of the course of wound healing is depicted in Figure 2. Hemostasis occurs immediately after dermal injury. The inflammation phase is characterized by cellular recruitment and increased vascular permeability. The epithelization phase is achieved by proliferation of basal cells and migration of epithelial cells. The last phase is known as the maturation and remodeling phase where collagen cross-linking and remodeling, wound contraction, and repigmentation takes place. Due to the broad involvement of various cell types, extracellular matrix and many reactive molecules each phase in wound healing produces characteristic changes within the tissue. A deficiency in any part of the process can lead to delayed wound healing, abnormal scar formation or chronic wounds. To study wound healing in healthy volunteers a challenge model with skin punch biopsies has been described in literature previously. However, the characterization of this model was not performed comprehensively since advanced analysis of biopsies were omitted. Furthermore, analyses performed in previous studies only partially described wound healing processes either by insufficient time points for characterization or scarce simultaneous evaluations of multiple wound healing modalities. The overall aim of this study is to develop a standardized model to temporarily and locally induce a skin trauma to investigate wound healing and monitor wound closure. This clinical model will enable future application as proof-of-pharmacology and proof-of concept studies as well as drug profiling in early drug development programs. More specifically, the objective of the trial is to explore and characterize the induction of well-defined skin trauma and natural wound healing process over the course of the different phases using a battery of dermatological assessments after skin punch biopsies in healthy volunteers. Furthermore, safety and tolerability will be assessed. Characterization and monitoring of wound healing effects following skin punch biopsies will be performed by means of biophysical, biochemical, imaging, clinical parameters and subject reported outcomes.
Cell-based engineered skin substitutes are promising to treat difficult-to-heal acute and chronic wounds such as large/deep burns, ulcers resistant to conventional therapies or surgical wounds. Cultured autologous epidermal cell-based therapy is used for more than two decades as permanent wound coverage for large burns. Although this technique has been shown to improve outcomes in patients with large burn injuries, its clinical use is limited by the creation of a second wound at the donor site, the three-week delay needed to obtain sufficient amounts of cells, and the absence of a dermal component resulting in low graft take and wound contraction. Concurrently, allogeneic cell-based engineered skin substitutes have been proposed. Where they offer off-the-shelf temporary wound coverage acting as biologically active dressings releasing growth factors, cytokines and extra cellular matrix components essential for proper wound healing, they are susceptible of immune rejection that is their major weakness Fetal skin, before the third trimester of gestational age, heals rapidly without scar formation conversely to adult skin. Minimal inflammation, specific cytokine and growth factor profiles, and faster and organized deposit and turnover of Extra Cellular Matrix (ECM) components during fetal wound healing have been proposed to explain the absence of scar formation. Because of their low immunogenicity, and their unique regeneration properties, fetal skin cells represent an attractive alternative to the commonly used autologous and allogenic cutaneous grafts. The investigators developed a new healing dressing constituted by a collagen sponge seeded with a specific ratio of active fetal fibroblasts and keratinocytes producing a variety of wound healing growth factors and cytokines which increase the speed of wound healing, induce an immunotolerant state, with a low inflammatory reaction. This prospective randomized controlled study aims to compare wound healing of CICAFAST versus conventional treatment (JELONET®) in the treatment of split-thickness skin graft donor site at D8. The patient will be his own control.
