Skin Wound

This study is a clinical trial testing the safety and efficacy of volar fibroblast (skin cells from the palm or sole) injections for thickening the epidermal (skin) layer at the stump site in people with below the knee amputations. The study will enroll adults seen at Johns Hopkins.

The goal of this clinical trial is to evaluate the safety and effectiveness of human umbilical cord mesenchymal stem cell (hUCMSC) therapy in patients undergoing medium-thickness skin grafts for donor site wounds. The study aims to answer the following main questions: * Question 1: Does hUCMSC therapy improve the healing quality and speed of donor site wounds in comparison to standard treatment? * Question 2: Does hUCMSC therapy reduce scar formation in the donor site wounds? Participants in this study will undergo medium-thickness skin grafts, and those in the treatment group will receive hUCMSC therapy. The main tasks for participants will involve regular follow-up visits, monitoring of wound healing progress, and assessment of any potential side effects or complications associated with the therapy. In order to evaluate the effectiveness of hUCMSC therapy, researchers will compare the treatment group receiving hUCMSC therapy with a control group that receives standard treatment alone. The aim is to determine if the use of hUCMSC therapy leads to improved healing outcomes and reduced scar formation compared to the standard treatment group.

This study is a randomised controlled trial to evaluate the skin closure time, parents' satisfaction, post operative mental health, wound cosmesis and wound complication of skin closure using adhesive glue, adhesive tape and suture in paediatric surgery patients. Primary objective is to compare skin closure time required by using adhesive glue, adhesive tape and suture. Secondary objectives are to compare parents' satisfaction, post operative mental health, wound cosmesis and wound complication of skin closure using adhesive glue, adhesive tape and suture in paediatric surgery patients. This study will be conducted from 26th August 2024 to 31st May 2025. It will take place at Hospital Pakar Kanak-Kanak UKM (HPKK), involving paediatric surgery patients undergoing clean or clean contaminated surgeries. The sample size calculated is 30 per group, a total of 90 patients for three groups. The sampling method used is simple random sampling method. In group A, skin will be closed using adhesive glue (Dermabond Mini, 0.36ml, Ethicon Johnson and Johnson, Somerville, New Jersey, USA). Skin closure in group B will be done using adhesive tape (Steri-StripsTM (3M, St. Paul, Minnesota, USA). In group C, skin will be closed using suture (Monosyn, B.Braun, 118 Pfieffewiesen, Melsungen, Germany) 4/0.
