Phoenixin and Pain in Pediatric Burn Patients

This prospective, controlled, observational study aims to investigate the relationship between phoenixin (PNX) levels and pain in pediatric burn patients. A total of 87 prepubertal children under 18 years of age will be included and evaluated in three independent groups: 29 children with second-degree burns in the acute burn period and experiencing pain at the time of assessment, 29 children with a history of burn injury at least three months previously who have completed the acute burn and procedural pain period, and 29 age-similar healthy controls without a history of burns or acute pain. Blood and urine samples will be collected from all participants, and PNX levels will be measured using an enzyme-linked immunosorbent assay (ELISA). Pain intensity will be assessed using age-appropriate validated pain assessment tools, including the Face, Legs, Activity, Cry, Consolability (FLACC) scale and the Visual Analog Scale (VAS), as appropriate. In the burn groups, burn characteristics, including total body surface area (TBSA), will also be recorded. The study will compare blood and urine PNX levels among the acute burn, chronic burn, and healthy control groups and will evaluate the relationship between PNX levels and clinical pain intensity in children with acute burns. Secondary analyses will examine the relationships between blood and urine PNX levels and their associations with TBSA and demographic and clinical characteristics. The findings are expected to provide preliminary clinical data on the potential role of PNX as a pain-related biological marker in pediatric burn patients.

Safety, Tolerability and Efficacy of Nefopam Cream in Burn Patients

Burn patients very commonly develop abnormal scars after injury which can be red, raised or elevated, painful and very itchy. They can prevent normal movement of hands and other joints and lead to ugly deformities which makes physical and psychological recovery very difficult. This proposal seeks to test the usefulness of a cream called Nefopam to prevent and treat these bad scars after burns and other injury to the skin. Nefopam is a drug that has been used as a pain medicine in Europe but has been found to have anti-scarring properties in rats and pigs. It has been tested in healthy people and found to be well tolerated and safe. The study purposes to make a scratch in the hip skin in 60 adult burn patients at two burn unit sites, the University of Alberta and the University of California at Davis, Sacramento CA. Burn patients in the study will have a scratch wound in the skin of the each side of the hip, part way through the thickness of the skin which is shallow at first but gets deeper. This scratch is made with a special guide which precisely controls the length and depth of the scratch so that each scratch is the same. Part of the scratch heals without scar and the deeper part heals with a red raised scar over a small region less than 2 inches long. One side will be treated with the drug and the other with a control or placebo are in a white cream that is indistinguishable, where you cannot tell which side contains the drug. Once the wound is nearly healed, usually less than 21 days, the cream will be applied twice daily for three weeks. Measurements will be done about once per month for four months where the healing scratches will be photographed, measurements of the thickness made with ultrasound and mexameter for scar color or pigment and redness. Ultrasound is a painless probe that uses sound waves to measure scar thickness and mexameter is a painless probe on the surface of the scratch to measure color and redness. Both measurements take only minutes to complete. Patients will be asked to answer a scar assessment form about on how they feel each scratch during the treatment and the research staff will also the complete scar form as well. It is the aim of the study to find a cream the works to prevent and reduce scarring after burn injury in military or civilian patients. In the future, an useful cream for scarring in burn patients may also be helpful for other skin damage which leads to scarring.

The Use of Cultured (Dermal) Epithelial Autografts in Severely Burned Patients

The Swisskera project is a multicenter follow-up study at the three Swiss burn centers evaluating long-term outcomes after burn wound coverage with lab-grown epithelial grafts, specifically cultured epithelial autograft (CEA) and, where applicable, cultured dermal-epidermal autograft (CDEA). Patients who received CEA/CDEA between 1985 and 2023 will be invited for a study visit , using available clinical records and standardized long-term scar and skin assessments. Long-term skin quality will be evaluated by comparing the previously transplanted area with a matched healthy skin reference site using non-invasive measurements (e.g., thickness, transepidermal water loss, hydration, elasticity, and color). Optional small punch biopsies may be obtained from transplanted areas (under local anesthesia or during clinically indicated anesthesia) for histological and immunohistochemical characterization of scar tissue remodeling, including collagen and elastin architecture, vascularization, nerve fiber ingrowth, inflammatory cell patterns, and melanocyte distribution.

Predictive Mortality Scales in the Burn Patient Admitted to the Intensive Care Unit

The data for this retrospective study were collected from the records of patients admitted to the intensive care unit (ICU) for burns at Hospital La Paz from January 1, 2019 to May 31, 2023.

Safety and Efficacy of realSKIN® to Provide Complete Wound Closure of Burn Wounds as an Alternative to Autografting

To evaluate the safety and efficacy of realSKIN® to provide complete wound closure of mixed-depth, full-thickness burn wounds as an alternative treatment to autografting.

A Study to Evaluate the Safety, Tolerability and Efficacy in Patients With Burn(s)

For Phase 1, researchers will explore the safety, and tolerability of PMS-101 and determine the recommended Phase 2 dose (RP2D) using the donor site. For Phase 2a, researchers will compare PMS-101 to a standard-of-care to see if PMS-101 works to treat mid-dermal burns.
