Regenerative Therapies for Basal Thumb Arthritis-A Systematic Review.

Basal thumb arthritis is a painful and debilitating pathology that can severely reduce a patients' quality of life. Common therapies include oral pain control, local steroid injections and/or surgery. Yet, therapeutic data on long-term improvement and even cartilage repair are scarce. This review aims to present the currently available literature on novel therapies for basal thumb arthritis, including platelet-rich plasma (PRP), fat grafting and phototherapy, and investigate their potential efficacy. The entire OVID database and PubMed were searched for studies containing the topics PRP injection, lipofilling, laser treatment and regenerative treatment for carpometacarpal arthritis. Seven studies on the effect of fat tissue on basal thumb arthritis were found. Four authors reported on PRP injections, one RCT examined a combinational treatment of PRP and fat grafting, another phototherapy for the thumb joint and one prospective trial on chondrocyte transplantation was found. Pain improvement and decreased impairment were reported in the majority of PRP and/or fat grafting studies as well as after chondrocyte implantation. Phototherapy did not significantly improve the condition. This review revealed that only limited data on regenerative therapies for carpometacarpal arthritis are currently available, yet PRP and lipofilling show promising results and merit further investigation.

Platelet-Rich Plasma in Plastic Surgery: A Systematic Review.

Introduction: Platelet-rich plasma (PRP) is gaining popularity and is applied in a variety of clinical settings. This review aims to present and evaluate available evidence regarding the use of PRP in various applications in plastic surgery. Methods: PubMed, Web of Science, Medline, and Embase were searched using predefined MeSH terms to identify studies concerning the application of PRP alone or in combination with fat grafting for plastic surgery. The search was limited to articles in English or German. Animal studies, in vitro studies, case reports, and case series were excluded. Results: Of 50 studies included in this review, eleven studies used PRP for reconstruction or wound treatment, eleven for cosmetic procedures, four for hand surgery, two for burn injuries, five for craniofacial disorders, and 17 as an adjuvant to fat grafting. Individual study characteristics were summarized. Considerable variation in preparation protocols and treatment strategies were observed. Even though several beneficial effects of PRP therapy were described, significance was not always demonstrated, and some studies yielded conflicting results. Efficacy of PRP was not universally proven in every field of application. Conclusion: This study presents an overview of current PRP treatment options and outcomes in plastic surgery. PRP may be beneficial for some indications explored in this review; however, currently available data are insufficient and systematic evaluation is limited due to high heterogeneity in PRP preparation and treatment regimens. Further randomized controlled trials employing standardized protocols are warranted.

Platelet-rich plasma for striae distensae: What do we know about processed autologous blood contents for treating skin stretchmarks?-A systematic review.

Striae distensae, also known as stretch marks, particularly associated with female sex, pregnancy, obesity, and/or hormonal change, are linear bands of benign dermal lesions. Although not posing any health risk, aesthetically unpleasing stretch marks can cause significant psychological distress among those affected. In abundance of therapeutic approaches, some literature sources proclaim platelet-rich plasma to be a promising treatment modality for striae distensae. We aimed to shed some light on the current literature evidence of platelet-rich plasma for treating stretch marks and performed an English literature analysis with two independent reviewers in accordance with PRISMA guidelines searching the PubMed and Web of Science databases in June 2019. Of the 12 found studies, 6 matched inclusion criteria. With no control groups in two, just two other reports used intraindividual comparisons, and all but one publication performed histopathological assessments. All studies observed clinical and subjective improvements without using validated scores or patient-reported outcome measures (PROMs). The main findings were that multiple treatments with platelet-rich plasma demonstrated increased epidermal thickness, rete ridges formation, and collagen/elastin formation, while decreasing the inflammatory cell infiltrate. The current literature evidence supporting the use of platelet-rich plasma for striae distensae is poor. We propose in this review an outline for a study protocol with intraindividual control groups, standardised scores, validated PROMs, and participant incentives to enhance the scientific power in future clinical trials.

Lessons Learned From Breast Implant Registries: A Systematic Review.

OBJECTIVE: Over several decades, numerous national and international registries on breast implants went online, aiming to collect prospective data to provide increased safety for patients and surgeons. We performed a review of all published data on breast implant registries to assess availability and quality of data and determine its usefulness and impact. MATERIALS AND METHODS: PubMed, Ovid, and Web of Science were searched to identify all articles containing breast implant registries in English language. The review was registered at PROSPERO (CRD42016041255) and performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. There was no limitation by publication date. RESULTS: Eight hundred ninety-five articles were identified; after removal of duplicates, 536 abstracts were screened on breast implant registries in plastic and reconstructive surgery. Unrelated articles, non-English articles, and not breast implant-related studies were excluded. Twenty breast implant registry-related articles met the inclusion criteria; 7 articles contained actual data on breast implants. Compared with international trends, only a minimal percentage of performed surgical breast augmentations is documented in registries, and the overall data quality and availability were low. CONCLUSIONS: Only a fraction of performed breast augmentations is documented properly in a registry. Currently, there are no published data based on a clinical quality registry. Sustained funding and reliable administrative governmental structures remain crucial to establish an adequate clinical quality registry for breast implants as currently launched in Australia to analyze outcomes and risk factors for an increased patient safety.

A new approach of assessing patient safety aspects in routine practice using the example of "doctors handwritten prescriptions".

AIMS AND OBJECTIVES: To test the method of self- and external assessment as a feedback system to decrease illegibility and incorrectness of handwritten prescriptions and to reduce additional workload for nursing staff. BACKGROUND: Illegibility and incorrectness of handwritten prescriptions occur very often and are the most crucial factors affecting patient safety. DESIGN: Self- versus external assessment using a 15 items checklist. METHODS: Nurses randomly selected five fever charts of their wards. Each fever chart was self- as well as externally assessed. Nurses and doctors took part in the self-assessment, and the external assessment was performed by external experts. According to a monitor suspension system, assessment results were considered "green," "yellow" or "red." After the first assessment and issuing feedback of the results "red" scored wards by the external assessment, additional trainings were performed. Thereafter, a second assessment was performed to rate eligibility and completeness of prescriptions. The research and reporting methodology followed squire 2.0. RESULTS: In total, 580 fever charts were self- as well as externally assessed (290 in each of the two assessment periods). Out of the 58 participating wards, 31 were surgical and 27 were non-surgical wards. Averaging over all checklist items, surgical and non-surgical wards improved only slightly over time. Linear regression models for ward means showed that there were significant improvements over time for non-surgical wards. CONCLUSIONS: This method directly involves those who commit errors and stimulate learning from errors. The approach of self- and external assessment was a useful instrument to detect inadequate prescriptions and to monitor improvements. RELEVANCE TO CLINICAL PRACTICE: Significant improvements were achieved regarding correctness and legibility of handwritten prescription and helped to decrease additional workload for nursing staff and thereby enhanced patient safety.

Three-Dimensional Evaluation of Static and Dynamic Effects of Botulinum Toxin A on Glabellar Frown Lines.

BACKGROUND: The use of injectable solutions for aesthetic purposes has increased tremendously, but lacks objective support. We aimed at assessing static and dynamic effects of botulinum toxin A (BoNTA) on glabellar lines by use of an objective three-dimensional methodology. METHODS: We prospectively collected three-dimensional stereographic photographs of two different facial expressions (pretreatment, 30 and 90 days posttreatment) in 21 patients, receiving a total of 20 units of BoNTA in both corrugator supercilii muscles. The primary endpoint was the three-dimensional static and dynamic surface irregularity, and secondary endpoints were the glabellar line scale and overall patient satisfaction. Blinded retrospective data analysis and statistical evaluation were performed with p < 0.05 considered statistically significant. RESULTS: Static glabellar lines (neutral facial expression) were significantly reduced by - 17% and - 24% on day 30 and 90 posttreatment, respectively (vs. pretreatment; both p < 0.0001). Dynamic glabellar frown lines (firmest possible bilateral eye closure) demonstrated a reduction of surface irregularity by - 26% and - 21% on day 30 and 90 posttreatment, respectively (vs. pretreatment; both p < 0.0001). The subjective dynamic glabellar line scale documented a statistically significant improvement on day 30 posttreatment (mean ± SD: 1.5 ± 0.8; p < 0.05) versus pretreatment (2.8 ± 1.0). Polled patients confirmed a subjective wrinkle improvement 90 days posttreatment. CONCLUSION: The presented setup detected even subtle changes of BoNTA treatment for facial wrinkling and is a promising asset for scientific evaluations of clinical studies analyzing the outcome and duration of efficacy of injectable solutions on the face.

The use of skin substitutes and burn care-a survey.

OBJECTIVE: The aim of our Internet survey was to assess the preferences of burn specialists who use skin substitutes in patients with burns covering 20% or more of their total body surface area (TBSA). METHODS: An open, voluntary Internet-based cross-sectional survey was performed. Responses to 19 noncompulsory questions, and participant career and location information were collected. RESULTS: One hundred eleven specialists from 36 countries responded to our questionnaire. Sixty participants were located in Europe (54%), followed by 31 (28%) in North America, 15 (14%) in Asia, three (3%) in South America, one (1%) in Africa, and one (1%) in Australia. The importance of skin substitutes in medium-sized burns (covering 20%-60% TBSA) was rated as "essential" by 28% and "desirable" by 56% of the respondents. In severe burns >60% of TBSA, 81% of responders rated the use of skin substitutes as "essential" and 14% as "desirable". Skin substitutes were used in daily clinical practice by 96% of all participants. Biological and synthetic dressings were used by 53%. A majority (86%) think that biological dressings do not pose a risk to patients. Allografts represent the most frequently used wound coverage (51%), followed by xenografts (28%). All participants of the survey indicated that as of yet, there is no ideal skin substitute available. CONCLUSIONS: Split-thickness autografts still represent the most used wound cover for definitive treatment of severe burns. However, creation and implementation of an ideal skin substitute have yet to be achieved and therefore should be the focus of future work.

Development of a cellular assay as a personalized model for testing chronic wound therapeutics.

Exudates of non-healing wounds contain drivers of pathogenicity. We utilized >800 exudates from non-healing and healing wounds of diverse etiologies, collected by three different methods, to develop a wound-specific, cell-based functional biomarker assay. Human dermal fibroblast proliferation served as readout to a) to differentiate between healing and non-healing wounds, b) follow the healing process of individual patients, and c) assess the effects of therapeutics for chronic wounds ex vivo. We observed a strong correlation between wound chronicity and inhibitory effects of individual exudates on fibroblast proliferation, with good diagnostic sensitivity (76-90%, depending on the sample collection method). Transition of a clinically non-healing to a healing phenotype restored fibroblast proliferation and extracellular matrix formation while reducing inflammatory cytokine production. Transcriptional analysis of fibroblasts exposed to ex vivo non-healing wound exudates revealed an induction of inflammatory cytokine- and chemokine pathways and the unfolded protein response, indicating that these changes may contribute to the pathology of non-healing wounds. Testing the wound therapeutics platelet derived growth factor and silver sulfadiazine yielded responses in line with clinical experience and indicate the usefulness of the assay to search for and profile new therapeutics.

The use of a polylactide-based copolymer as a temporary skin substitute in deep dermal burns: 1-year follow-up results of a prospective clinical noninferiority trial.

Deep dermal burns can be covered with different kind of materials and techniques; one of them is a polylactide-based temporary skin substitute. The aim of this study was to intraindividually compare its 1-year outcome with the results obtained by use of autologous skin grafts in patients suffering from deep dermal burns. A prospective noninferiority trial was designed in order to assess skin quality and scar formation by use of subjective (Vancouver Scar Scale; Patient and Observer Scar Assessment Scale) and objective (noninvasive cutometry) burn scar assessment tools. All items of the Patient and Observer Scar Assessment Scale, except vascularity, were found to be noninferior in the areas covered with the temporary skin substitute vs. autologous skin. Results of objective scar evaluation showed comparable viscoelastic parameters without reaching noninferiority. Overall, the outcome of deep dermal burns covered with a polylactide-based temporary skin substitute revealed satisfactory results in terms of scar formation and skin quality as compared with autologous skin. This paper supports its use in deep dermal burns, where autologous skin donor sites require either to be reserved for coverage of full-thickness skin defects in severe burns or to be saved for reduction of additional morbidity in selected patient collectives.

Autologous Fat and Platelet-Rich Plasma Injections in Trapeziometacarpal Osteoarthritis: A Systematic Review and Meta-Analysis.

BACKGROUND: For the treatment of carpometacarpal arthritis of the thumb, various therapies are used. Infiltration therapy with autologous substances such as platelet-rich plasma and autologous fat have recently gained increasing attention because of beneficial pain-reducing effects in arthritis and the associated regenerative potential. However, the extent of clinical evidence in this area and how well autologous substances work in terms of pain reduction and improvements in hand function remain unclear. METHODS: A systematic review and meta-analysis were conducted to evaluate the current evidence and to provide more insight into pain reduction and improvement in hand function after infiltration of autologous substances. The authors identified 11 clinical trials, of which we included eight in the meta-analysis. RESULTS: Autologous substances achieved a good and long-lasting pain reduction, which may also be accompanied by corresponding improvement in hand function. Autologous substances appear to be more effective than corticoid infiltrations. The infiltration of autologous fat seems to be particularly promising in more advanced stages of carpometacarpal arthritis of the thumb. Our meta-analysis showed a mean pain reduction of 2.4 to 3 in visual analogue scale score and a reduction of 18 to 19 points in the Disabilities of the Arm, Shoulder, and Hand questionnaire after infiltration with autologous substances. CONCLUSION: Both platelet-rich plasma and autologous fat infiltration offer an efficient and long-lasting, minimally invasive therapy option in the treatment of carpometacarpal arthritis of the thumb.

Minimally Invasive Treatment of Trapeziometacarpal Osteoarthritis: Results of a Blinded Randomized Controlled Trial.

BACKGROUND: Surgical therapy for widespread first carpometacarpal (CMC1) arthritis permanently alters the physiologic anatomy of the hand. The injection of autologous substances into the thumb saddle joint could achieve temporary pain relief and delay surgical indications. This trial aimed to compare the pain-reducing effects of autologous fat and/or platelet-rich plasma (PRP) with saline 0.9% in the infiltration therapy of carpometacarpal arthritis of the thumb (CMC1 arthritis). METHODS: A blinded, randomized controlled trial was conducted. Ninety-five patients with CMC1 arthritis were included in the study. The mean follow-up period was 2 years. Participants were injected with 1.5 mL of autologous fat, PRP, autologous fat and PRP, or 0.9% saline solution into the CMC1 joint, depending on the group allocation. The primary outcome of this study was the evaluation of pain reduction in each treatment group. RESULTS: The combination of fat and PRP was the only treatment that resulted in a significantly greater reduction in pain compared with 0.9% saline ( P = 0.003). Similarly, fat and PRP in combination was the only therapy group to achieve clinically relevant Quick Disabilities of Arm, Shoulder, and Hand score reduction, and the only group that showed a significantly better Medical Outcomes Study 36-Item Short-Form Health Survey score than 0.9% saline ( P = 0.016). No major complications were noted. CONCLUSIONS: In addition to pain reduction, the combination of autologous fat and PRP yields a relevant improvement in hand function and a corresponding improvement in quality of life. This treatment seems to be a viable and safe alternative to short-acting glucocorticoids. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

Radiological Influencing Factors in the Diagnosis of Painful Habitual Instability of the Thumb Basal Joint as a Precursor of Carpometacarpal Arthritis of the Thumb-A Retrospective Study.

BACKGROUND: Painful habitual instability of the thumb basal joint (PHIT) is a rarely diagnosed condition that can severely impair hand function. Furthermore, it can increase the risk of developing carpometacarpal arthritis of the thumb (CMAOT). Clinical examination and radiographic imaging provide the foundation for a correct diagnosis, but early detection is still challenging. We investigated two objective, radiographically obtainable parameters as potential risk factors for PHIT. METHODS: Clinical data and radiographic images of 33 patients suffering from PHIT were collected and compared to those of 35 people serving as the control group. The two main objectives, the slope angle and the bony offset of the thumb joint, were gathered from the X-rays and statistically analyzed. RESULTS: The analysis showed no differences between the study and the control group concerning the slope angle. Gender and the bony offset, on the other hand, had a significant influence. Female sex and higher offset values were associated with an increased risk of PHIT. CONCLUSIONS: The results of this study prove a connection between a high bony offset and PHIT. We believe this information can be valuable in early detection and will allow more efficient treatment of this condition in the future.

Does Electrical Stimulation through Nerve Conduits Improve Peripheral Nerve Regeneration?-A Systematic Review.

BACKGROUND: Peripheral nerve injuries affect over 2% of trauma patients and can lead to severe functional impairment and permanent disability. Autologous nerve transplantation is still the gold standard in the reconstruction of nerve defects. For small defects, conduits can be considered for bridging. Lately, the combined use of conduits and electrical stimulation has gained attention in the treatment of peripheral nerve injury. This review aimed to present the currently available data on this topic. METHODS: PubMed, Embase, Medline and the Cochrane Library were searched for studies on electrical stimulation through nerve conduits for nerve defects in in vivo studies. RESULTS: Fifteen studies fit the inclusion criteria. All of them reported on the application of nerve conduits combined with stimulation for sciatic nerve gaps in rats. Functional, electrophysiological and histological evaluations showed improved nerve regeneration after electrical stimulation. High variation was observed in the treatment protocols. CONCLUSION: Electrically stimulated conduits could improve peripheral nerve regeneration in rat models. The combined application of nerve guidance conduits and electrical stimulation shows promising results and should be further evaluated under standardized conditions.

Donor site morbidity after the harvest of microvascular flaps from the medial and lateral femoral condyle region: Objective, radiologic, and patient-reported outcome of a multi-center trial.

BACKGROUND: With the experience-based hypothesis of low donor site morbidity (DSM) for free flaps from the distal femur, this cohort study aimed to evaluate the DSM according to objective and reproducible criteria. METHODS: One hundred and fifty-six patients who had a flap harvest from either the medial or lateral femoral condyle region between 2005 and 2017 were included. A retrospective chart review was performed for all patients. In total, 97 patients were available for a follow-up examination. Outcomes were assessed according to objective (Knee Society Score; Larson Knee Score; OAK Score; 0-100 points), patient-reported (IKDC Score; KOOS Score; 0-100 points), and radiologic criteria (Kellgren and Lawrence Score; MRI Osteoarthritis Knee Score). RESULTS: The median follow-up time was 1529 days (range: 248-4,810). The mean Knee Society Score (94.8 ± 10.1), Larson Knee Score (94.5 ± 10.1), and OAK Score (95.5 ± 6.6) showed nearly unimpaired knee function. The overall patient-reported DSM was low (IKDC Score: 86.7 ± 17.4; KOOS Score: 89.3 ± 17.1). Osteochondral (OC) flaps had a significantly higher DSM, regardless of the donor site. Bone flaps did not show any relevant radiologic morbidity in the Kellgren and Lawrence Score. Besides the procedure-associated cartilage lesions at the OC donor sites, MRI Osteoarthritis Knee Score did not show any significant presence of further knee pathologies in the bilateral MRI Scans. The obvious cartilage lesions did not have a relevant impact on the knee function of most patients. CONCLUSION: The DSM for bone and soft-tissue flaps from the femoral condyle region is negligible. OC flaps are associated with a significantly higher DSM, although a clinically relevant impact on knee function was not evident in the majority of patients.

Pathophysiology of burns.

Burn injury represents a significant problem worldwide. Advances in therapy strategies, based on better understanding of the pathophysiologic responses after burn injury have improved the clinical outcome of patients with burn injuries over the past years. This article describes the present understanding of the pathophysiology of a burn injury including both the local and systemic responses, focusing on the many facets of organ and systemic effects directly resulting from hypovolemia and circulating mediators following burn trauma.

BMI and specimen weight: impact on personalized risk profiling for optimized informed consent in breast reduction surgery?

We aimed to evaluate the interaction between individual risk factors and institutional complication rates after reduction mammaplasties to develop a chart for a personalized written patient informed consent. We retrospectively reviewed charts of 804 patients who underwent bilateral breast reduction between 2005 and 2015. The Clavien-Dindo classification was used to classify postoperative complications. Relevant predictors were found by applying a stepwise variable selection procedure. Multilevel predictors were assessed through chi-square tests on the respective deviance reductions. 486 patients were included. The most common complications were wound healing problems (n = 270/56%), foreign body reactions (n = 58/12%), wound infections (n = 45/9, 3%) and fat tissue necrosis (n = 41/8%). The risk factors for the personalized patient chart for the most common complications influencing the preoperative informed consent were: smoking, operative technique, resection weight for wound healing problems; body mass index and allergies for wound infections; and patients' age, resection weight for fat tissue necrosis. The resultant chart of institutionally encountered most common complications based on individual risk factors is a graphical template for obtaining patient informed consent in the future. Whether this approach influences patient information retainment, incidence of filed lawsuits or behavioral change needs to be prospectively tested in future studies.

What can we learn from sonication results of breast implants?

BACKGROUND: Different research groups have identified microorganisms on breast implants by sonication with significant correlation to the rate of capsular contracture. This substantiated the hypothesis of an infectious etiology of capsular contracture. However, no clinical consequence has been drawn from these results yet. Aim of this study was to review sonication results from breast implants and to evaluate the current preoperative antibiotic regime for breast-implant surgery. METHODS: We compared breast implant sonication culture results from published reports and our own database. Current perioperative antibiotic recommendations were compared with the susceptibility profile of the found organisms. RESULTS: We found Coagulase-negative staphylococci and Propionibacteria to be the main group of microorganism found by sonication on explanted breast implants. Most guidelines recommend cephalosporins for preoperative antibiotical prophylaxis for breast-implant surgery. CONCLUSION: There is a discrepancy between antibiotic activity of commonly used antibiotics for preoperative prophylaxis of surgical site infections, and microorganisms found by sonication on breast implants, suspected to trigger the formation of capsular contracture. A targeted antibiotic prophylaxis for breast implant surgery with glycopeptides (e.g. Vancomycin) should be considered for the prevention of capsular contracture.

Human herpes viruses in burn patients: A systematic review.

OBJECTIVE: The contribution of human herpes viruses, including herpes simplex virus (HSV), cytomegalovirus (CMV), and varicella zoster virus (VZV) to morbidity and mortality after burns remains controversial. This systematic review was undertaken to assess evidence of herpes virus-related morbidity and mortality in burns. MATERIALS AND METHODS: PubMed, Ovid, and Web of Science were searched to identify studies of HSV, CMV, or VZV infections in burn patients. Exclusion criteria included: A level of evidence (LoE) of IV or V; nonhuman in vivo studies; and non-English articles. There was no limitation by publication date. RESULTS: Fifty articles were subjected to full-text analysis. Of these, 18 had LoE between I-III and were included in the final review (2 LoE I, 16 LoE II-III). Eight had a prospective study design, 9 had a retrospective study design, and 1 included both. CONCLUSIONS: No direct evidence linked CMV and HSV infection with increased morbidity and mortality in burns. Following burn, CMV reactivation was more common than a primary CMV infection. Active HSV infection impaired wound healing but was not directly correlated to mortality. Infections with VZV are rare after burns but when they occur, VZV infections were associated with severe complications including mortality. The therapeutic effect of antiviral agents administered after burns warrants investigation via prospective randomized controlled trials.

Standardizing the complication rate after breast reduction using the Clavien-Dindo classification.

BACKGROUND: Published complication rates for breast reduction surgery, also known as reduction mammaplasty, vary between 4% and 54%. This wide range of complication rates could be attributable to the lack of a standardized classification of complications in plastic surgery. The aim of this study was to analyze our single-center complication rates after reduction mammaplasty using the Clavien-Dindo classification. METHODS: We performed a retrospective chart review studying 804 patients between the ages of 18 and 81 years old who underwent breast reduction between 2005 and 2015 at our institution. Patients with a history of breast cancer, a previous breast operation, who did not undergo bilateral reduction mammaplasty, or who required systemic immunodeficiency/immunosuppressive drugs were excluded from our analysis. Complications were classified according to the Clavien-Dindo classification from Grades I to V. RESULTS: A total of 486 patients met the inclusion criteria for the analysis. Patients had an age (mean ± standard deviation) of 39 ± 13 years and a body mass index of 26 ± 4 kg/m2. Median follow-up was 274 days (interquartile range: 90.5-378). The overall rate of complications of reduction mammaplasty was 63%, with the majority of those being Grades I (48%) and II (9%), comprising 92% of all the complications. Operative revisions were required in 6% (1% Grade IIIA and 5% Grade IIIB). There were no complications graded in categories IV and V. CONCLUSION: Although complications occurred in more than half of the cases, the majority did not require operative reintervention. The Clavien-Dindo classification can classify the severity of complications and serve as a benchmark to compare complication rates between different practices. We believe that grading of complications should distinguish between those that do and do not require operative reinterventions.

Two-year follow-up of outcomes related to scarring and distress in children with severe burns.

PURPOSE: We assessed the perception of scarring and distress by pediatric burn survivors with burns covering more than one-third of total body surface area (TBSA) for up to 2 years post-burn. METHODS: Children with severe burns were admitted to our hospital between 2004 and 2012, and consented to this IRB-approved-study. Subjects completed at least one Scars Problems and/or Distress questionnaire between discharge and 24 months post burn. Outcomes were modeled with generalized estimating equations or using mixed linear models. Significance was accepted at p < 0.01. RESULTS: Responses of 167 children with a mean age of 7 ± 5 years and burns covering an average 54 ± 14% of TBSA were analyzed. Significant improvements over the 2-year period were seen in reduction of pain, itching, sleeping disturbance, tightness, range of motion, and strength (p < 0.01). There was a significantly increased persistent desire to hide the scarred body areas over time (p < 0.01). The perception of mouth scarring, inability to portray accurate facial expressions, and skin coloration did not improve over the follow-up period. CONCLUSIONS: According to self-assessment questionnaires, severely burned children exhibit significant improvements in their overall perception of scarring and distress. However, these patients remain self-conscious with respect to their body image even 2 years after burn injury. Implications for Rehabilitation According to self-assessment questionnaires, severely burned children perceive significant improvements in scarring and distress during the first 2 years post burn. Significant improvements were seen in reduction of pain, itching, sleeping disturbances, tightness, range of motion, and strength (p < 0.01). Burn care providers should improve the treatment of burns surrounding the mouth that with result in scarring, and develop strategies to prevent skin discoloration. Careful evaluation of pain and sleeping disorders during the first year post burn are warranted to improve the patient rehabilitation. Overall, significantly more female patients expressed a persistent desire to hide their scarred body areas. The rehabilitation team should provide access to wigs or other aids to pediatric burn survivors to address these needs.
