Article Synopsis
  • * In a randomized controlled trial, one group received standard outpatient care while the other group, aided by an ECC, received additional support through scheduled phone calls and coordination of services related to rehabilitation.
  • * Ultimately, the study found no significant differences in patient outcomes between the two groups after 6 and 12 months, although all participants valued the personalized goal-setting process provided by the ECC.

Pruritus (itching) is a common and distressing complaint after injury. The purpose of this study was to investigate self-reported postburn pruritus in a large, multisite cohort study of adult burn survivors. Descriptive statistics, general linear regression, and mixed model repeated measures analyses were employed to test statistical significance.

Background: Burn demographics, prevention and care have changed considerably since the 1970s. The objectives were to 1) identify new and confirm previously described changes, 2) make comparisons to the American Burn Association National Burn Repository, 3) determine when the administration of fluids in excess of the Baxter formula began and to identify potential causes, and 4) model mortality over time, during a 36-year period (1974-2009) at the Harborview Burn Center in Seattle, WA, USA.

Methods And Findings: 14,266 consecutive admissions were analyzed in five-year periods and many parameters compared to the National Burn Repository.

Background: Hypertrophic scar was first described over 100 years ago; PubMed has more than 1,000 references on the topic. Nevertheless prevention and treatment remains poor, because 1) there has been no validated animal model; 2) human scar tissue, which is impossible to obtain in a controlled manner, has been the only source for study; 3) tissues typically have been homogenized, mixing cell populations; and 4) gene-by-gene studies are incomplete.

Methodology/principal Findings: We have assembled a system that overcomes these barriers and permits the study of genome-wide gene expression in microanatomical locations, in shallow and deep partial-thickness wounds, and pigmented and non-pigmented skin, using the Duroc(pigmented fibroproliferative)/Yorkshire(non-pigmented non-fibroproliferative) porcine model.

Growing evidence indicates that the melanocortin 1 receptor (MC1R) and its ligand α-melanocyte-stimulating hormone (α-MSH) have other functions in the skin in addition to pigment production. Activation of the MC1R/α-MSH signaling pathway has been implicated in the regulation of both inflammation and extracellular matrix homeostasis. However, little is known about the role of MC1R/α-MSH signaling in the regulation of inflammatory and fibroproliferative responses to cutaneous injury.

A number of factors increase the susceptibility of older adults to burn injury. The majority of studies of older adults have focused on patient and injury factors related to mortality risk. However, little is known about the long-term functional and psychological outcomes of older adults after severe burn.

Pressure garment therapy is standard of care for prevention and treatment of hypertrophic scarring after burn injury. Nevertheless there is little objective data that confirms effectiveness. The purpose of this study was to determine the effectiveness of pressure garment therapy with objective data obtained with a randomized within-wound comparison.

Few studies have empirically investigated the effects of immersive virtual reality (VR) on postburn physical therapy pain control and range of motion (ROM). We performed a prospective, randomized controlled study of the effects of adding VR to standard therapy in adults receiving active-assisted ROM physical therapy, by assessing pain scores and maximal joint ROM immediately before and after therapy on two consecutive days. Thirty-nine inpatients, aged 21 to 57 years (mean 35 years), with a mean TBSA burn of 18% (range, 3-60%) were studied using a within-subject, crossover design.

Article Synopsis
  • * Utilizing a Q-sort task, researchers had participants rank 50 potential distress reasons on a game board, enabling them to analyze these responses effectively.
  • * The results revealed four distinct groups of distress themes among the 69 participants at various post-discharge time points, suggesting this method can lead to targeted interventions for burn survivors’ needs.

During the past decades there has been minimal improvement in prevention and treatment of hypertrophic scarring. Reasons include the lack of a validated animal model, imprecise techniques to dissect scar into the histologic components, and limited methodology for measurement of gene expression. These problems have been addressed with the Duroc/Yorkshire model of healing, laser capture microdissection, and the Affymetrix Porcine GeneChip.

Management and proper approach to pediatric palm burns remains unclear. Our burn center's approach includes early, aggressive range of motion therapy, combined with a period of watchful waiting, reserving grafting only for those palms that do not heal in a timely manner. We reviewed our experience using this approach over a 10-year period.

Background: A subset of obese people develop a pannus hanging to the floor. This panniculus morbidus prevents weight loss, as the patient cannot exercise. It prevents hygiene, leading to a profound odor and ultimately results in intertrigo, cellulitis, and/or abdominal ulceration.

Article Synopsis
  • The study aimed to assess whether the Burn Model System (BMS) population accurately represents the broader burn population and identify any validity threats in a dataset of severe burns.
  • The data were gathered from 5 burn centers in the U.S. since 1994 and compared against the National Burn Registry (NBR), which includes information from 70 hospitals across the U.S. and Canada.
  • Results indicated that while there were minor demographic differences, the BMS population is valid for research purposes, highlighting the need for careful analysis in future studies.

Hypertrophic scarring after burns is an unsolved problem and remains as devastating today as it was in the 40s and it may be that the main reason for this is the lack of an accepted, useful animal model. The female, red Duroc pig was described as a model of hypertrophic scarring nearly 30 years ago but then vanished from the literature. This seemed strange since the authors reported that 12 of 12 pigs developed thick scar.

Introduction: Burns create a myriad of complications that affect the child's developmental, functional and aesthetic status. The WeeFIM is a standardized measure of functional performance developed for use in children 6-months to 8-years of age but with application through adolescence. It includes 18 domains of performance which are scored on a 7-point scale from 'total assistance' to 'complete independence'.

Returning to school is an important indicator of functional aptitude and emotional adjustment in school-aged patients after burn injury. Only two reports in the burn literature provide objective data on time to school re-entry. However, these analyses did not address the impact of patient and burn injury characteristics on time to return to school.

Heterotopic ossification (HO) is a well-recognized complication of burn injury that can result in significantly compromised limb function. The etiology and optimal treatment strategy for HO remain elusive. The purpose of this study was to examine the relationship between delay in elbow wound closure and the development of HO.

The female red Duroc pig has been found to be a promising model of hypertrophic scarring. The female Yorkshire pig has been demonstrated to heal in a very different manner, more resembling human normotrophic scarring. Given these observations, we studied microvessel density, an important aspect of wound healing, in human hypertrophic scars and the scars of the female Duroc and Yorkshire pigs.

Background: Fascial closure after damage control or decompression laparotomy is not always possible. The result is a ventral hernia covered with skin grafts. Massive hernias impair bowel, bladder, and respiratory function and are displeasing aesthetically.
