Abstract
As the overall survival rate for burn injury has improved, increased emphasis is placed on postburn morbidity and the optimization of functional and cosmetic outcomes. One major cause of morbidity and functional deficits is that of joint contractures. The true incidence of postburn contractures and their associated risk factors remains unknown. This study examines the incidence and severity of contractures in a large, multicenter, burn population. The associated risk factors for the development of contractures are determined. Data from the National Institute on Disability and Rehabilitation Research Burn Model System database, for adult burn survivors from 1994 to 2003, were analyzed. Demographic and medical data were collected on each subject. The primary outcome measures included the presence of contractures, number of contractures per patient, and severity of contractures at each of nine locations (shoulder, elbow, hip, knee, ankle, wrist, neck, lumbar spine, and thoracic spine) at time of hospital discharge. Regression analysis was performed to determine predictors of the presence, severity, and numbers of contractures, with P < .05 used for statistical significance. Of the 1865 study patients, 620 (33%) developed at least 1 contracture at hospital discharge. Among those with at least one contracture, the mean is three (3.38) contractures per person. The shoulder was the most frequently contracted joint (23.0%), followed by the elbow (19.9%), wrist (17.3%), ankle (13.6%), and knee (13.4%). Most contractures were mild (47.2%) or moderate (32.9%) in severity. Statistically significant predictors of contracture development were male sex, black race, Hispanic ethnicity, medical problems, neuropathy, TBSA grafted, and TBSA burned. Predictors of the severity of contracture included male sex, black race, medical problems, neuropathy, TBSA grafted, and TBSA burned. Predictors of the number of contractures included male sex, medical problems, flash burn, neuropathy, TBSA burned, and TBSA grafted. Similar to a previous single-center study on postburn contractures, approximately one third of the patients with an eligible burn injury requiring autografting developed a contracture at hospital discharge. It is likely that these contractures develop despite early therapeutic interventions such as positioning and splinting; therefore, the challenge to the burn community remains, to identify new and better prevention strategies.

Abstract
Joint contractures are a major cause of morbidity and functional deficit. The incidence of postburn contractures and their associated risk factors in the pediatric population has not yet been reported. This study examines the incidence and severity of contractures in a large, multicenter, pediatric burn population. Associated risk factors for the development of contractures are determined. Data from the National Institute on Disability and Rehabilitation Research Burn Model System database, for pediatric (younger than 18 years) burn survivors from 1994 to 2003, were analyzed. Demographic and medical data were collected on each subject. The primary outcome measures included the presence of contractures, number of contractures per patient, and severity of contractures at each of nine locations (shoulder, elbow, hip, knee, ankle, wrist, neck, lumbar, and thoracic) at time of hospital discharge. Regression analysis was performed to determine predictors of the presence, severity, and numbers of contractures, with P < .05 used for statistical significance. Of the 1031 study patients, 237 (23%) developed at least 1 contracture at hospital discharge. Among those with at least one contracture, the mean was three (3.3) contractures per person. The shoulder was the most frequently contracted joint (27.9%), followed by the elbow (17.6%), wrist (14.2%), knee (13.3%), and ankle (11.9%). Most contractures were mild (38.5%) or moderate (36.3%) in severity. The statistically significant predictors of contracture development were age and intensive care unit (ICU) length of stay. The statistically significant predictors of severity of contracture were age, ICU length of stay, presence of amputation, and black race. Predictors of the number of contractures included total age, length of stay, length of ICU stay, presence of amputation, TBSA burned, and TBSA grafted. This is the first study to report the epidemiology of postburn contractures in the pediatric population. Approximately one quarter of children with a major burn injury developed a contracture at hospital discharge, and this could potentially increase as the child grows. Contractures develop despite early therapeutic interventions such as positioning and splinting; therefore, it is essential that we identify novel and more effective prevention strategies.

Abstract
Background There is a lack of rigorous research investigating the factors that influence scar outcome in children. Improved clinical decision-making to reduce the health burden due to post-burn scarring in children will be guided by evidence on risk factors and risk stratification. This study aimed to examine the association between selected patient, injury and clinical factors and the development of raised scar after burn injury. Novel patient factors were investigated including selected immunological co-morbidities (asthma, eczema and diabetes type 1 and type 2) and skin pigmentation (Fitzpatrick skin type). Methods A prospective case-control study was conducted among 186 children who sustained a burn injury in Western Australia. Logistic regression was used to explore the relationship between explanatory variables and a defined outcome measure: scar height measured by a modified Vancouver Scar Scale (mVSS). Results The overall correct prediction rate of the model was 80.6%; 80.9% for children with raised scars (>1 mm) and 80.4% for children without raised scars (≤1 mm). After adjustment for other variables, each 1% increase in % total body surface area (%TBSA) of burn increased the odds of raised scar by 15.8% (95% CI = 4.4–28.5%). Raised scar was also predicted by time to healing of longer than 14 days (OR = 11.621; 95% CI = 3.727–36.234) and multiple surgical procedures (OR = 11.521; 1.994–66.566). Conclusions Greater burn surface area, time to healing of longer than 14 days, and multiple operations are independently associated with raised scar in children after burn injury. Scar prevention strategies should be targeted to children with these risk factors.

Abstract
Revlous research identifies a number of variables that influence psychological adjustment following a burn injury. The aim of this literature review is to investigate the types of support available for adult burns patients and their value in the adjustment process and subsequent return to work. It concludes that social support is valuable during rehabilitation but that greater professional support is required.

Abstract
Hypertrophic scarring is extremely common and is the source of most morbidity related to burns. The biology of hypertrophic healing is complex and poorly understood. Multiple host and injury factors contribute, but protracted healing of partial thickness injury is a common theme. Hypertrophic scarring and heterotopic ossification may share some basic causes involving marrow-derived cells. Several traditional clinical interventions exist to modify hypertrophic scar. All have limited efficacy. Laser interventions for scar modification show promise, but as yet do not provide a definitive solution. Their efficacy is only seen when used as part of a multimodality scar management program.

Abstract
PURPOSE A systematic literature review was undertaken to gather evidence to develop a guideline for vocational evaluation following burn injuries (BI). This review aimed to identify the key processes evaluators should follow and the key factors they should consider when completing such evaluations. METHODS Steps outlined in Cochrane Handbook of Systematic Review were followed including: development of review question; search strategies and selection criteria; quality appraisal; data extraction; analysis & synthesis; drawing conclusions. Four databases (Pubmed, Medline, CINHAL, PsycINFO) and 14 websites were searched for relevant articles and studies (quantitative, qualitative), reviews and guidelines. Two reviewers independently completed reviews, performed quality assessments and extracted data into evidence tables. Using the ICF model and directed content analysis, key processes and factors were analyzed and synthesized across the evidence. RESULTS A total of 138 articles were identified using the key words (e.g. burns, work). Studies, reviews and guidelines were retrieved if they focused on adults and discussed the processes relevant to vocational evaluation and/or factors associated with successful return to work (RTW) following a BI. Items were excluded if they did not address adults who had suffered a burn, the process of work or RTW, or challenges related to work after a BI. Using the above criteria 76 items were retrieved for full review. Fifty-six items remained after the quality appraisal. Results were integrated to develop the Evidence-based Framework for Vocational Evaluation Following Burn Injury. CONCLUSIONS This framework outlines 7 key processes relevant to vocational evaluation following burn injuries.

Abstract
The objective of this work is to develop and validate a numerical model that can conduct a transient analysis of heat transfer and the corresponding damage in skin burns. Once this model is developed, an examination of the effect of cooling on reducing damage from skin burns is carried out. A finite element numerical model is used to simulate the conduction of heat and the transient progress of irreversible injury in the skin. The damage function of Henriques and Moritz is used to model the damage that occurs in the skin during the burn and cooling periods. Numerical results are presented that describe the heat transfer during a skin burn. Comparison is made between different burns: a high-temperature, short-duration burn (99°C for 1 second) and a medium-temperature, long-duration burn (80°C for 15 seconds). Cooling parameters such as the nature of the cooling fluid, the duration of the cooling period, the temperature of the coolant fluid, and the delay between the termination of the burn and the initiation of the cooling therapy are examined. The authors find that the most influential way to significantly reduce the damage from a burn is to immediately cool the burn. In addition, it was found that cooling a burn for a prolonged period of time or with very cold water cannot be justified from purely a heat transfer point of view.

Abstract
This study compares employment rates and barriers to return to work in subjects burned at work with those burned outside of work. Further, this study examines the influence of electrical etiology on return to work outcomes. The electronic records of burn survivors treated at a Regional Burn Center outpatient clinic from 2001 to 2007 were retrospectively reviewed. Inclusion criteria included employment at the time of burn injury and age of 18 years or older. Demographic and medical data were collected. Documentation of barriers to return to work was reviewed and classified into eight categories. Return to employment was grouped into four time intervals: 0 to 3, 3 to 6, 6 to 12, and greater than 12 months after injury. Logistic regression analysis was used to determine predictors of unemployment at greater than 1 year for subjects burned at work, outside of work, and those burned at work without electric injury. The authors identified 197 patients for inclusion in the study. Their age was 37 ± 0.8 years (mean ± SEM), and TBSA burned was 16 ± 1%. Fifty percent of subjects were burned at work. Electric etiology was seen only in those burned at work (n = 24). Forty-four percent (n = 43) of subjects injured at work remained unemployed at 1 year compared with 22% (n = 22) of subjects injured outside of work. The most frequent employment barriers included pain (72%), neurologic problems (62%), and psychiatric problems (53%) for those burned at work; and pain (63%), neurologic problems (59%), and impaired mobility (54%) for those burned outside of work. Significant predictors of unemployment at greater than 12 months included burn at work, pain, impaired mobility, other medical problems, and inpatient rehabilitation (P < .05). When the electrical injury subjects are removed from the analysis, significant predictors of unemployment at 12 months include burn at work, pain, inpatient rehabilitation, and length of stay (P < .05). Burn survivors experience multiple complex barriers in returning to work. Burn at work is a significant predictor of unemployment at 1 year even after controlling for electric etiology. Further study is required to better understand the influence of work setting on employment outcomes.

Abstract
Burn induces a sustained catabolic response which causes massive loss of muscle mass after injury. A better understanding of the dynamics of muscle wasting and its impact on muscle function is necessary for the development of effective treatments. Male Sprague-Dawley rats underwent either a 40% total body surface area (TBSA) scald burn or sham burn, and were further assigned to subgroups at four time points after injury (days 3, 7, 14 and 21). In situ isometric contractile properties were measured including twitch tension (Pt), tetanic tension (Po) and fatigue properties. Body weight decreased in burn and sham groups through day 3, however, body weight in the sham groups recovered and increased over time compared to burned groups, which progressively decreased until day 21 after injury. Significant differences in muscle wet weight and protein weight were found between sham and burn. Significant differences in muscle contractile properties were found at day 14 with lower absolute Po as well as specific Po in burned rats compared to sham. After burn, the muscle twitch tension was significantly higher than the sham at day 21. No significant difference in fatigue properties was found between the groups. This study demonstrates dynamics of muscle atrophy and muscle contractile properties after severe burn; this understanding will aid in the development of approaches designed to reduce the rate and extent of burn induced muscle loss and function.

Abstract
Occupational therapy aims to help patients resume their occupations. Therefore, we must know their work status after our intervention. We collected demographic and burn-related data from patient charts and analyzed it to determine the work status of former patients with burned hands and what influenced their returning to work. From 284 former patients with burns, we screened 159 with burned hands, 108 of whom were interviewed through the telephone about their work status. We used logistic regression analysis to analyze factors for having work, returning to work, the length of time required to return to work, and job modifications. We found that 1) having preburn employment increased the likelihood of having postburn employment; 2) being the primary wage earner in a family increased the likelihood of having work and of a return to work postburn; 3) a longer stay in the hospital, and burn injuries on both hands and trunk increased the time required to return to work; and 4) being older and having a smaller percentage of total body burn area decreased the likelihood of returning to a job modified because of a burn injury. Returning to work was affected not only by burn-related factors but also by general demographic and employment factors. We urge occupational therapy departments to include a return-to-work program in their routine services to improve the chances of patients with hand burns to return to work. We strongly recommend that a multicenter prospective study of hand-burn injuries should be performed.

Abstract
STUDY DESIGN Case report. INTRODUCTION A combined burn and a partial amputation can be extremely debilitating as the thumb constitutes 40% of the entire hand when evaluating functional impairment. PURPOSE OF THE STUDY Measure disability with and without opposition splint use after partial thumb amputation due to a burn. METHODS Impairment and disability measures were completed at discharge from the hospital and subsequently during outpatient follow-up visits while wearing and not wearing a thumb opposition splint at 3, 6, 8, and 15 months. Comparisons between disability and impairment scores were assessed over time. RESULTS The difference between DASH scores with and without using the splint were 25 at 3 months, 16 at 6 months, 10 at 8 months, and 12 at 15 months. CONCLUSIONS Splint use in this case demonstrated clinically significant changes over time with minimal changes in impairment indicating enhanced function and improved patient perception of disability.

Abstract
Previous literature on necrotizing soft tissue infections (NSTIs) has focused on its diagnosis and high mortality, but to our knowledge, none have reported on the functional outcomes of patients surviving this devastating disease. The purpose of this study was to evaluate the management and assess factors associated with decreased physical function in patients who survived this life-threatening infection. A retrospective review was conducted on patients treated for NSTI in whom an evaluation of functional status was performed between 2002 and 2006. Measurements were based on the American Medical Association Guides of impairment rating, and categorized into a functional class from "minimal or no limitation" to "severe limitation." Multivariate analyses were performed to discern independent factors associated with functional limitation. Final disposition status after discharge was also recorded. A total of 297 patients were treated for NSTI during this time. Of these, 119 (41%) patients met inclusion criteria for review. Mean number of débridements and coverage procedures were 3.4 and 2.0, respectively. Although mean percent functional limitation was 7.1, which is classified as "minimal or no limitation," 30% of patients had "mild" to "severe" functional limitation. Extremity involvement was independently associated with a higher functional limitation class (P < .01). Functional limitation may challenge recovery from NSTI in many survivors. In this series, the involvement of an extremity predicted a higher functional limitation class at the time of discharge. Development of validated functional assessment tools and accurate longitudinal follow-up are necessary to measure the functional impact of NSTI.

Abstract
As yet no qualitative research studies looking at return to work following burns have been published. The aim of this study was to investigate the "hows" and "whys" of return to work, by purposively selecting a cross-section of burns patients who returned to the same/similar job, those who returned to work but either on a part-time basis or in a different role/job and those who became or remained unemployed, and using semi-structured interviews to explore their experiences. Using matrix analysis methodology, and with the general themes that emerged from these transcripts, it was possible to place patients into 5 broad groups, the "defeated", the "burdened", the "affected", the "unchanged" and the "stronger". We anticipate that use of these general groups will be useful in targeting multi-disciplinary return to work strategies, and discuss how this qualitative research has changed practice at the Queen Victoria Hospital Burns Centre.

Abstract
Burn rehabilitation has been a part of burn care and treatment for many years. Yet, despite of its longevity, the rehabilitation outcome of patients with severe burns is less than optimal and appears to have leveled off. Patient survival from burn injury is at an all-time high. Burn rehabilitation must progress to the point where physical outcomes parallel survival statistics in terms of improved patient well-being. This position article is a treatise on burn rehabilitation and the state of burn rehabilitation patient outcomes. It describes burn rehabilitation interventions in brief and why a need is felt to bring this issue to the forefront. The article discusses areas for change and the challenges facing burn rehabilitation. Finally, the relegation and acceptance of this responsibility are addressed.

Abstract
This study evaluated the use of the American Medical Association (AMA) impairment guides and Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire in U.S. military casualties recovering from burn injury to the hand. Study sample included patients with burns to at least one hand and complete evaluations of impairment and disability upon discharge from the hospital and at a follow-up visit less than four months later. AMA and DASH scores were calculated for each visit and standardized response means (SRMs) were calculated to indicate responsiveness. Correlation between impairment and disability was assessed at discharge and follow-up and scores were examined for ability to discriminate between casualties returned to duty (RTD) and casualties not returned to duty (N-RTD). Both outcome instruments revealed a statistically significant change in scores between visits (p<0.001) with corresponding SRM indexes greater than 0.8 (large effect). There was a moderate correlation (r=0.50) between impairment and disability at discharge and a moderately high correlation (r=0.74) at follow-up. Both AMA and DASH scores clearly discriminated between casualties RTD (AMA 10+/-10 and DASH 12+/-12) and casualties N-RTD (AMA 39+/-19 and DASH 41+/-17) with improved accuracy at follow-up visit. The AMA and DASH can provide a comprehensive assessment of impairment and disability and may be used to detect changes in patient health status over time while clearly discriminating between RTD and N-RTD in combat casualties recovering from burn injury to the hand(s).

Abstract
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. In the mid 90s we explored the model and found that, indeed, the red Duroc pig does make thick scar. Other authors have established that the Yorkshire pig does not heal in this fashion so there is the possibility of a same species control. We have continued to explore the Duroc/Yorkshire model and herein describe our experiences. Is it a perfect model of hypertrophic scarring? No. Is it a useful model of hypertrophic scarring? Time will tell. We have now obtained gene expression data from the Duroc/Yorkshire model and analysis is underway.

Abstract
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. The purpose of this study was to determine the time for school re-entry and to identify the factors associated with re-entry time in a cohort of burned children treated at our burn center. We performed a retrospective review of all school age children treated at our burn center from 1997 to 2003 who were entered into a federally funded longitudinal research database for patients with severe burn injury. Time to school re-entry after discharge was calculated for each patient, and multivariate regression was used to identify the factors associated with longer time to return to school. A total of 64 patients were included in this study. The average time to school re-entry was 10.5 days (range, 0-40) and the median time was 7.5 days. Gender (male), age, and length of hospital stay were significantly associated (P < .05) with longer time to return to school. The average time to school return is quite short. Further studies are needed to increase understanding of the factors influencing longer time to re-entry and also to examine children's experiences upon re-entry.

Abstract
The etiology and treatment of hypertrophic scar remain puzzles even after decades of research. A significant reason is the lack of an accepted animal model of the process. The female, red Duroc pig model was described long ago. Since the skin of the pig is similar to that of humans, we are attempting to validate this model and found it to be encouraging. In this project we quantified myofibroblasts, mast cells and collagen nodules in the thick scar of the Duroc pig and compared these to the values for human hypertrophic scar. We found the results to be quite similar and so further validated the model. In addition, we observed that soon after wounding an inflammatory cell layer forms. The thickness of the inflammatory layer approaches the thickness of the skin removed as if the remaining dermis "knows" how much dermis is gone. In deep wounds this inflammatory layer thickens and this thickness is predictive of the thickness of the ultimate scar.

Abstract
We conducted a Medline search (1966-11/2003) on empirical studies into the consequences of burns. The International Classification of Functioning, disabilities and health (ICF) was used to classify dimensions of functional outcome. We included 50 studies, reporting a wide spectrum of ICF-dimensions. The current state of knowledge on the functional outcome after burns was hard to summarise, due to the wide variety in study designs and outcome assessment methods. Some indications on the major functional problems after burns were gained. Problems in mental function were described in subgroups of patients, both in children/adolescents and adults. Restrictions in range of motion were observed in about one-fifth of burn patients, even 5 years after injury. Problems with appearance were reported often (up to 43%), even in patients with minor burns (14%). Problems with work were reported in 21-50% of the adult patients, with permanent incapacity for work in 1-5%. None of the publications gave sufficient information to fully estimate the functional consequences of burns. We recommend the development of a standard core set for measurement and reporting of functional outcome after burns.

Abstract
BACKGROUND Keloid scars represent a pathological response to cutaneous injury. Overproliferation of fibroblasts and overproduction of collagen characterize these abnormal scars. The pathology of these scars remains poorly understood. The role of epithelial-mesenchymal interactions in keloid pathogenesis and scar contracture has recently been explored. OBJECTIVES To test our hypothesis that epithelial-mesenchymal interactions play a major role in modulating keloid scar contracture. METHODS A coculture model was employed wherein keloid and normal keratinocytes were cocultured with keloid or normal fibroblasts, and the conditioned media from day 5 cocultures were collected to study the effect of the paracrine secretions on contraction of an in vitro fibroblast-populated collagen lattice (FPCL) model. RESULTS Keloid keratinocyte/keloid fibroblast coculture conditioned media brought about increased contraction of the collagen lattice compared with non-cocultured conditioned media. When keloid fibroblasts populated the collagen lattice, significantly increased lattice contraction was induced compared with lattices populated by normal fibroblasts. The addition of antitransforming growth factor (TGF)-beta neutralizing antibody to the conditioned media produced an attenuation of the contraction of the FPCLs. When keloid and normal fibroblasts were cultured on chamber slides and treated with conditioned media from coculture and non-coculture series, immunohistochemical analysis demonstrated an increased expression of alpha-smooth muscle actin (a marker for fibroblast differentiation into myofibroblasts) in fibroblasts exposed to conditioned media from coculture. CONCLUSIONS These data indicate that epithelial-mesenchymal interactions are likely to play a major role in scar contracture and scar pathogenesis, and underscore the role of TGF-beta1 as a key player in keloid pathogenesis.

Abstract
Wound contraction in humans has both positive and negative effects. It is beneficial to wound healing by narrowing the wound margins, but the formation of undesirable scar contracture brings cosmetic and even functional problems. The entire mechanism of wound healing and scar contracture is not clear yet, but it is at least considered that both the fibroblasts and the myofibroblasts are responsible for contraction in healing wounds. The myofibroblast is a cell that possesses all the morphologic and biochemical characteristics of both a fibroblast and a smooth muscle cell. Normally, the myofibroblasts appear in the initial wound healing processes and generate contractile forces to pull both edges of an open wound until it disappears by apoptosis. But as an altered regulation of myofibroblast disappearance, they remain in the dermis and continuously contract the scar, eventually causing scar contracture. In this research, to compare and directly evaluate the influence on scar contracture of the myofibroblast versus the fibroblast, dermal tissues were taken from 10 patients who had highly contracted hypertrophic scars. The myofibroblasts were isolated and concentrated from the fibroblasts using the magnetic activating cell-sorting column to obtain the myofibroblast group, which contained about 28 to 41 percent of the myofibroblasts, and the fibroblast group, which contained less than 0.9 percent of the myofibroblasts. Each group was cultured in the fibroblast-populated collagen lattice for 13 days, and the contraction of the collagen gel was measured every other day. In addition, they were selectively treated with tranilast [N-(3',4'-dimethoxycinnamoyl) anthranilic acid] to evaluate the influence on the contraction of the collagen gel lattice. During the culture, the myofibroblast group, compared with the fibroblast group, showed statistically significant contraction of the collagen gel lattice day by day, except on the first day, and only the myofibroblast group was affected by tranilast treatment, showing significant inhibition of gel contraction. By utilizing an in vitro model, the authors have demonstrated that myofibroblasts play a more important role in the contracture of the hypertrophic scar.

Abstract
Impairment rating is regularly reported for trauma and other conditions but rarely for burns. The purposes of this study were: (1) to report impairment collected prospectively at our burn center, (2) to relate this impairment to measures of psychosocial and functional outcome, and (3) to compare these data to similar data from another burn center to verify that rating impairment is standardized and that the impairments are similar. We studied 139 patients from the University of Washington (UW) Burn Center and 100 patients from the University of Texas (UT) Southwestern Burn Center. The average whole person impairment (WPI) ratings at the University of Washington were 17% and this correlated with total body surface area burned and days off work. It did not correlate with Brief Symptom Inventory (BSI), Functional Independence Measure (FIM), Short-Form 36-Item Health Survey (SF-36), Satisfaction With Life Scale (SWLS), and the Community Integration Questionnaire (CIQ). Average whole person impairment ratings at UT Southwestern were similar at 19%. Several components of the impairment rating, however, differed at the two institutions. To minimize this variation, we recommend: (1) use the skin impairment definitions of the fifth edition of the Guides to the Evaluation of Permanent Impairment (or the most recent published versions of the Guide), and (2) include sensory impairment in healed burns and skin grafts in the skin impairment.

Abstract
The present study investigates factors influencing the quality of life and social reintegration of burn victims. A study concept was developed to assess the functional and aesthetic long-term outcomes of burn victims. Objective data from a clinical examination was correlated with subjective data from completed questionnaires. The success of social rehabilitation was documented and an indicative profile of life quality evaluated. This profile could prompt early intervention if found necessary. Ninety-two patients were examined 5.4+/-1.1 years after trauma in relation to three factors: physical functions, localization of the burn injuries and extent of the body surface area burned. Physical functioning allows the best predictions for successful rehabilitation, because all areas of life quality are affected by it. Localization of burns in the face and hands creates disadvantages in social reintegration. Of less value in prediction is the extent of the body surface area burned, which is only closely linked to occupational rehabilitation and directly correlates to physical functional limitations. Our correlation showed, that even slight functional limitations were linked to severe depressions, similar to the values found with patients with serious functional impairment. Interdisciplinary cooperation between plastic surgeons and psychosomatic specialists will optimize early intervention with patients exposed to social maladaptation.

Abstract
BACKGROUND Hypertrophic scars (HSc) are a dermal fibroproliferative disorder that leads to considerable morbidity. Preliminary evidence suggests that interferon (IFN) may improve HSc clinically. The aims of this study were (1) to compare the cell density in HSc and in wounds that heal without the development of HSc (normotrophic scars), (2) to examine the presence of myofibroblasts and apoptosis in normotrophic and HSc scars over time, and (3) to determine if the systemic administration of IFN-alpha2b can induce apoptosis. METHODS Two groups of patients underwent serial tissue biopsies. Six burn patients were studied prospectively by obtaining biopsy specimens from wound granulation tissue, normal skin, post-burn HSc, and normotrophic scars (healed donor sites). A second patient group with HSc was treated with systemic IFN-alpha2b and had biopsy material taken before, during, and after IFN therapy. The tissue was analyzed by immunohistochemical staining for alpha-smooth muscle actin (alpha-SMA) and in situ DNA fragmentation terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assay for apoptosis. RESULTS The total numbers of fibroblasts in HSc were found to be similar to granulation tissue and twice that of normal skin and normotrophic scar. Over time the numbers of cells in HSc tissue decreased toward normal skin levels. There was a significantly higher percentage of fibroblasts staining for alpha-SMA in HSc as compared with normotrophic scar or normal skin obtained from the same patient (P >.05). Serial biopsy specimens of resolving HSc tissue obtained from the patients who received systemic IFN-alpha2b showed a general reduction in total number of fibroblasts and myofibroblasts associated with a significant increase in the percentage of apoptotic cells compared with normal dermis from the same patient. CONCLUSIONS HSc tissues have greater numbers of fibroblasts and myofibroblasts than normal skin and normotrophic scars. As HSc remodels, the numbers of fibroblasts and myofibroblasts reduces, possibly by the induction of apoptosis. Systemic IFN-alpha2b may contribute to the resolution of HSc in part by the enhanced induction of apoptosis.

Abstract
The literature on time off work and return to work after burns is incomplete. This study addresses this and includes a systematic literature review and two-center series. The literature was searched from 1966 through October 2000. Two-center data were collected on 363 adults employed outside of the home at injury. Data on employment, general demographics, and burn demographics were collected. The literature search found only 10 manuscripts with objective data, with a mean time off work of 10 weeks and %TBSA as the most important predictor of time off work. The mean time off work for those who returned to work by 24 months was 17 weeks and correlated with %TBSA. The probability of returning to work was reduced by a psychiatric history and extremity burns and was inversely related to %TBSA. In the two-center study, 66% and 90% of survivors had returned to work at 6 and 24 months post-burn. However, in the University of Washington subset of the data, only 37% had returned to the same job with the same employer without accommodations at 24 months, indicating that job disruption is considerable. The impact of burns on work is significant.

Abstract
Calculating impairment in burn patients is crucial to understanding outcome. However, it is rarely reported after burns, presumably because the process of calculating impairment ratings is complicated and tedious. Computerized systems have been developed that facilitate the process, but it has not been established in burn patients that these systems reduce the time required to calculate impairment. We evaluated the Dexter Evaluation and Therapy System by Cedaron Medical Inc (Davis, CA). A sample of 10 manually recorded ratings was compared with 10 performed on the Dexter. Mean time for the manual technique was 65 +/- 35 minutes versus 37 +/- 13 minutes for the Dexter (P < .05, Mann-Whitney). The time taken to perform impairment ratings in burn survivors is significantly reduced by the use of the Dexter system. Time saving occurs primarily at three points: (1) electronic data entry directly from the measuring instruments, (2) compilation of data, and (3) rapid generation of reports.

Abstract
The purpose of this study was to compare the efficacy and effects of exercise programming (Study group, n = 11) vs traditional outpatient therapy (Home group, n = 10) in burned children (> 40% body surface area). This was a prospective, randomized, controlled trial in a hospital-based children's wellness center. Twenty-one patients (13 boys and 8 girls) averaging 10.6 +/- 0.9 years and TBSA = 59.7 +/- 3.1% were evaluated 6 and 9 months postburn. Moderate intensity, progressive resistance and aerobic exercise conducted 3 times weekly for 1 hour were a supplement to standard therapy over 12 weeks. Muscular strength and functional outcome significantly increased in both groups (P < .05). Improvements in strength (80.1 vs 37.7%) and distance walked (39.5 vs 12.5%) were significantly greater for Study vs Home groups, respectively, P < .05. We conclude that exercise programming may be safely included in rehabilitation programs for severely burned children and can be effective in increasing muscular strength and functional outcome.

Abstract
Evaluation of community integration is a meaningful outcome criterion after major burn injury. The Community Integration Questionnaire (CIQ) was administered to 463 individuals with major burn injuries. The CIQ results in Total, Home Integration, Social Integration, and Productivity scores. The purposes of this study were to determine change in CIQ scores over time and what burn injury and demographic factors predict CIQ scores. The CIQ scores did not change significantly from 6 to 12 to 24 months postburn injury. Home integration scores were best predicted by sex and living situation; Social Integration scores by marital status; and Productivity scores by functional outcome, burn severity, age, and preburn work factors. The data demonstrate that individuals with burn injuries have significant difficulties with community integration due to burn and nonburn related factors. CIQ scores did not improve over time but improvement may have occurred before the initial 6-month postburn injury follow-up in this study.

Abstract
BACKGROUND Hypertrophic scars (HS) are frequent consequences of deep dermal injury, such as deep partial-thickness burns and abrasions, and are characterized by overproduction of collagen. In vitro studies have shown that cultured HS fibroblasts produce elevated levels of collagen and insulin-like growth factor-binding protein 3 (IGFBP-3). Additionally, histological studies have indicated HS contain fewer tumor necrosis factor alpha (TNF-alpha)-positive infiltrating cells and express lower levels of TNF-alpha mRNA, suggesting TNF-alpha, which can inhibit collagen expression in some systems, may function to deactivate the wound healing process in scars. HS also exhibit increased levels of transforming growth factor beta (TGF-beta), a factor that stimulates collagen and extracellular matrix deposition by fibroblasts and also stimulates IGFBP-3 expression. In some systems, IGFBP-3 mediates the effects of TGF-beta. The present study sought to determine the effects of continuous and transient TNF-alpha exposure on collagen and IGFBP-3 expression by cultured HS fibroblasts and to investigate the role of IGFBP-3 in collagen accretion by HS fibroblasts. MATERIALS AND METHODS Superficial and deep dermal HS fibroblasts from four patients were cultured. Fibroblasts were cultured in serum-free medium and exposed to 0-2 ng/ml TNF-alpha for 0, 1, 4, or 72 h. After 72 h of culture, medium samples were processed for Western blot analysis of type I collagen accumulation or for ligand blot analysis of IGFBP-3 accumulation. The effects of an anti-IGFBP-3 neutralizing antibody on collagen accumulation were also assessed. RESULTS Treatment of superficial and deep HS fibroblasts with TNF-alpha resulted in dose-dependent decreases in accumulation of both type I collagen and IGFBP-3 in the culture medium (P < 0.01). However, using the anti-IGFBP-3 neutralizing antibody, a causal relationship between decreased IGFBP-3 and decreased collagen accumulation could not be demonstrated. Transient exposure of cultured HS fibroblasts to TNF-alpha for as little as 1 h was as effective as continuous exposure to TNF-alpha for 72 h in inhibiting collagen accumulation. CONCLUSIONS These results support the hypothesis that TNF-alpha functions as a wound healing deactivation signal that is deficient in HS. Although TNF-alpha inhibited accretion of both collagen and IGFBP-3, the role of IGFBP-3 in HS remains unresolved. This study suggests that transient TNF-alpha exposure may be used to inhibit collagen overaccumulation in HS and that the timing of TNF-alpha exposure following dermal injury may not be critical for this inhibition.

Abstract
Estudos prévios têm demonstrado que o ácido hialurônico, um glicosaminoglicano que ocorre em doses elevadas e por tempo prolongado na matriz extracelular dos tecidos em cicatrização do feto, é o responsável pelo resultado da cicatrização fetal sem marcas residuais e sem contração. O presente estudo investigou a ação tópica do ácido hialurônico em queimaduras de ratos adultos, até a epitelização completa das lesões. Foram usados 20 ratos Wistar com peso médio 225± 15g, nos quais foi provocada queimadura de 5 cm2 na pele do dorso, sob anestesia com éter sulfúrico. No grupo I (n=10) as queimaduras foram tratadas com aplicação tópica diária de 1ml de ácido hialurônico 1% e no grupo II (n=10) com 1ml de solução salina 0,9%, até a completa epitelização. O tempo de cicatrização foi de 29± 1,33 dias no grupo I e 38± 2,58 no grupo II. A média dos escores histológicos foi de 27,0± 2,78 no grupo I e de 18,1± 3,66 no grupo II. As diferenças mostraram-se significantes (p<0,05). A análise do resultado estético revelou maiores deformidades nas cicatrizes do grupo II (controle). Concluiu-se que o ácido hialurônico tópico contribuiu para acelerar o tempo de cicatrização, melhorou a evolução histológica e o resultado estético em queimaduras do dorso de ratos adultos.

Abstract
This paper provides an overview of thermal injury resulting in death or hospitalization in New Zealand adults, defined as age 15 years and over. For the 10-year period 1978-1987, there were 493 adult thermal injury deaths resulting in an overall rate of 2.1 per 100000 person-years (95%CI: 1.9-2.3). For the year 1988, there were 644 hospitalizations resulting in a rate of 25.1 per 100000 (95%CI: 23.2-27.1). The highest rates of death and hospitalization were observed in the elderly (65 years of age and over). Young males (15-29 years) also had a very high rate of hospitalization. Residential fire was the most common type of burn event resulting in death (44%), and smoking materials were the most common source of ignition in fatal residential fires (37%). Hot liquids were the most common source of thermal energy for the hospitalized injuries (34%). Typical scenarios involved burns from hot water expelled from automobile radiators, from hot water use in the workplace, from hot beverages, and from household hot tap-water. The epidemiology of the adult thermal injuries in New Zealand is similar to that reported in other developed countries. Opportunities and strategies for the prevention of these injuries are discussed.

Abstract
Keloids, hypertrophic scars, and contractures are a result of aberrations of the normal wound healing process. An understanding of the cellular and molecular events that are implicated in the development of these fibroproliferative disorders will allow for optimization of wound healing. In turn, treatment choices can be based on the most current scientific information available.

Abstract
The increase in the survival rate of burned patients has stressed the need to study their rehabilitation. The purpose of our study was to characterize the factors influencing such patients' return to work. We conducted a mail survey among 316 patients aged 15-65 years, treated at Töölö Hospital Burns Unit between 11 November 1988 and 31 December 1994. Of 175 participants, 130 (74 per cent) were men and 45 (26 per cent) women. The mean TBSA was 14.0 per cent, mean FT 6.4 per cent and the mean time of hospital treatment (TOT) 17.5 days. Statistical significance was calculated by Mann-Whitney U test, Kruskall-Wallis one-way analysis of variance and Chi-square test as appropriate, with a probability level of 0.05. In the study, 54 per cent of patients whose burn area was 1-10 per cent, returned to work within 2 months. No difference was found between patients who had hand burns and those who had burn injuries in other parts of the body. Patients who did not return to work were significantly older (mean age 45 years) than those who did (mean ages varying from 33 to 36 years; P < 0.05). Total body surface area burned (TBSA), FT, TOT, age and employment status at the time of injury were the factors predicting the resumption of working ability after burn injury.
