Long-term outcomes of a cultured autologous dermo-epidermal skin substitute in children: 5 year results of a phase I clinical trial.

Limited donor sites and poor long-term outcomes with standard treatment for large skin defects remain a huge problem. An autologous, bilayered, laboratory-grown skin substitute (denovoSkin™) was developed to overcome this problem and has shown to be safe in ten pediatric patients in a phase I clinical trial after transplantation. The goal of this article is to report on 48 months long-term results. The pediatric participants of the phase I clinical trial were followed at yearly visits up to five years after transplantation. Safety parameters including occurrence of adverse events, possible deviations of vital signs and changes in concomitant therapy as well as additional parameters regarding skin stability, scar quality and tumor formation were assessed. Furthermore, scar maturation was photographically documented. From the ten patients treated with denovoSkinTM in this phase I clinical trial, seven completed the five-year follow-up period. Skin substitutes continued to be deemed safe, remained stable and practically unchanged, with no sign of fragility, and no tumor formation at clinical examination. Scar quality, captured by applying the Patient and Observer Scar Assessment Scale, was evaluated as close to normal skin. Transplantation of this laboratory-grown skin substitute in children is to date considered safe and shows encouraging functional and aesthetical long-term results close to normal skin. These results are promising and highlight the potential of a life-saving therapy for large skin defects. A multicentre, prospective, randomized phase II clinical trial to further evaluate the safety and efficacy of this novel skin substitute is currently ongoing.

As time goes by - Overlooking 40 years of inpatient burn treatment at a national pediatric burn center in Switzerland.

BACKGROUND: Despite extensive prevention programs, burns remain a frequent cause of injury in Switzerland with a known age peak in children. Pediatric burns may cause substantial morbidity, a psyochological burden and therapy related high economic costs. To improve preventive measures, precise knowledge of etiology and treatment of pediatric burns in Switzerland as well as their temporal evolution is indispensable. METHODS: The present retrospective analysis included pediatric burn patients admitted for acute treatment to the Pediatric Burn Center of the University Children`s Hospital Zurich over the last four decades. Sociodemographic, injury related, and treatment related data were extracted from medical records. Linear regression analysis was applied to determine temporal changes during the past four decades and chi-square and t-tests were applied wherever applicable. RESULTS: A total of 3425 acute burn patients were included in the study between 1977 and 2020, corresponding to a mean of 89 patients/year. Mean age was 3.60 ± 4.12 years, three quarters of all patients were preschool children (0-5 years) and mean total body surface area (TBSA) burned was 8.01% ± 9.57%, however only around one fifth had severe burns (>10% TBSA). Scald burns (65.31%) and flame burns (32.99%) were most commonly seen. Linear regression analysis showed the total number of thermal injuries treated at our center to have increased significantly as of 2004 (p < 0.001). Separate analysis showed the same for small and medium (<10% TBSA) burns (p < 0.001), whereas the number of severe burns did not increase significantly. Length of stay (LOS) was highly associated with %TBSA burned. The percentage of female patients amongst all patients increased over time (p = 0.012). LOS per TBSA burned decreased significantly (p < 0.001). CONCLUSION: The present data show pediatric burns to remain a major health burden in Switzerland, especially small and medium burns in preschool children. Prevention programs should focus on this age population as well as on scald and flame burns as most common etiologies. The observed decrease in length of stay suggests a major improvement in overall quality of care in pediatric burns and supports centralization of care.

Management of a fusiform brachial artery aneurysm associated with birth trauma.

Brachial artery aneurysms in children are rare. Surgical treatment is generally recommended.We present the case of a female toddler with a pulsatile swelling on the medial aspect of the right upper arm without history of recent trauma. Medical history revealed a traumatic birth with labour arrest. Postnatally diffuse trunk and arm haematomas as well as a temporary right arm discolouration were detected. Preoperative ultrasound revealed a true brachial artery aneurysm. A full-body MRI ruled out any accompanying lesions. Primary resection and end-to-end anastomosis were performed. Recovery was uneventful. 6-month and 12-month follow-up showed normal motor function and arterial patency; ultrasound also demonstrated harmonious growth of the anastomosed vessel segments.No other publication has associated birth trauma with brachial artery aneurysm yet. Correct diagnosis and prompt curative surgery are key to prevent severe complications. Further reports and data on long-term outcome are needed to optimise clinical management.

Psychosocial health and psychological adjustment in adolescents and young adults with congenital melanocytic nevi: Analysis of self-reports.

This study assessed self-reported health-related quality of life and psychological adjustment in 43 adolescents and young adults (ages in years: 14-24, M = 17.6, SD = 2.2) with congenital melanocytic nevi (CMN) and examined associations with sociodemographic variables, characteristics of the CMN, perceived social reactions, and cognitive emotion regulation strategies. Outcome measures included the Pediatric Quality of Life Inventory™ 4.0 and the Strengths and Difficulties Questionnaire. Findings suggest impaired psychosocial health and psychological adjustment in youth with CMN compared to community norms. Impairments were associated with higher age of participants, lower socioeconomic status, visibility of the skin lesion, perceived stigmatization, poorer perceived social support, and maladaptive cognitive emotion regulation strategies (self-blame, rumination, and catastrophizing), but not with sex of participants, extent of the skin lesion, and surgical removal of the nevus. Implications for clinical practice and future research are discussed.

Analysis of Plastic Surgery Consultations in a High-Volume Paediatric Emergency Department: A Quality Improvement Initiative.

INTRODUCTION: Consult services influence emergency department (ED) workflow. Prolonged ED length of stay (LOS) correlates with ED overcrowding and as a consequence decreased quality of care and satisfaction of health team professionals. To improve management of paediatric ED patients requiring plastic and reconstructive surgery (PRS) expertise, current processes were analyzed. METHODS: Patient characteristics and metrics of PRS consultations in our paediatric ED were collected over a 3-month period. Data analysis was followed by feedback education intervention to ED and PRS staff. Data collection was then resumed and results were compared to the pre-intervention period. RESULTS: One hundred ninety-eight PRS consultations were reviewed, mean patient age was 6.3 years. Most common (52%) diagnoses were burns and hand trauma; 81% of PRS referrals were deemed appropriate; 25% of PRS consults were requested after hour with no differences in patient characteristics compared to regular hours; 60% of consultations involved interventions in the ED. Time between ED registration and PRS consultation request (116.5 minutes), quality of procedural sedation (52% rated inadequate), and overall ED LOS (289.2 minutes) were identified as main areas of concern and addressed during feedback education intervention. Emergency department LOS and quality of sedation did not improve in the post-intervention period. CONCLUSION: The study provides detailed insights in the characteristics of PRS consultation in the paediatric ED population. Despite high referral appropriateness and education feedback intervention, significant inefficiencies were identified that call for further collaborative efforts to optimize quality of care for paediatric ED patients and improve satisfaction of involved healthcare professionals.

INTRODUCTION: Les services de consultation ont une influence sur le cheminement à l'urgence. Une durée de séjour prolongée à l'urgence est corrélée avec le surpeuplement de l'urgence et, par conséquent, une diminution de la qualité des soins et de la satisfaction des équipes de professionnels de la santé. Pour améliorer la prise en charge des patients à l'urgence pédiatrique qui ont besoin de compétences en chirurgie plastique et reconstructive (CPR), les chercheurs ont analysé les processus actuels. MÉTHODOLOGIE: Les chercheurs ont colligé les caractéristiques des patients et les mesures des consultations en CPR dans une urgence pédiatrique sur une période de trois mois. Ils ont suivi l'analyse des données d'une intervention de rétroaction au personnel de l'urgence et de la CPR. Par la suite, ils ont repris la collecte de données pendant trois mois et l'ont comparée à la période précédant l'intervention. RÉSULTATS: Les chercheurs ont examiné 198 consultations en CPR, chez des patients d'un âge moyen de 6,3 ans. Les diagnostics les plus courants (52 %) étaient les brûlures et les traumatismes de la main. Les chercheurs ont considéré 81 % des orientations en CPR comme appropriées. Ils ont constaté que 25 % des consultations en CPR ont été demandées après les heures de travail, sans que les caractéristiques de patients soient différentes de celles demandées pendant les heures normales. Ils ont remarqué que 60 % des consultations étaient liées à des interventions à l'urgence. Ils ont déterminé que le délai entre l'inscription à l'urgence et la demande de consultation en CPR (116,5 minutes), la qualité de la sédation lors de l'intervention (52 % étaient classées comme inappropriées) et la durée globale du séjour à l'urgence (289,2 minutes) étaient les points les plus préoccupants et ont été abordés lors de l'intervention de rétroaction. La durée du séjour à l'urgence et la qualité de la sédation ne se sont pas améliorées après l'intervention. CONCLUSION: L'étude fournit des points de vue détaillés des caractéristiques de la consultation en CPR au sein de la population à l'urgence pédiatrique. Malgré le taux élevé d'orientations appropriées et l'intervention de rétroaction, les chercheurs ont constaté d'importantes inefficacités qui justifient plus d'efforts de collaboration pour optimiser la qualité des soins auprès des patients à l'urgence pédiatrique et pour accroître la satisfaction des professionnels de la santé en cause.

Sleep behavior of infants with infantile hemangioma treated with propranolol-a cohort study.

Sleep problems are frequently reported in infants treated with propranolol for infantile hemangiomas, possibly serving as a marker for a negative impact on central nervous system function. In this cohort study, we objectively investigate the sleep behavior of infants with infantile hemangiomas on propranolol compared to a healthy, untreated control group. Sleep of propranolol-treated infants and controls was investigated using ankle actigraphy and a 24-h diary for 7-10 days at ages 3 and 6 months. The main outcome measures were the Number of Nighttime Awakenings and Sleep Efficiency. The main secondary outcome measures included 24-hour Total Sleep, daytime sleep behavior, and parent-rated infant sleep quality and behavioral development based on the Brief Infant Sleep Questionnaire (BISQ) and the age-appropriate Ages-and-Stages Questionnaire (ASQ), respectively. Fifty-four term-born infants were included in each cohort. No group difference in any investigated parameter was seen at age 3 months. At age 6 months, the propranolol group exhibited a decrease in Sleep Efficiency and a trend towards an increased Number of Nighttime Awakenings compared to the control group. Treated infants at 6 months also had shorter daytime waking periods. 24-hour Total Sleep was unaffected by propranolol. No negative impact of propranolol on subjective sleep quality and behavioral development was noted.Conclusion: Propranolol exerts a measurable yet mild impact on objectively assessed infants' sleep measures. Behavioral developmental scores were unaffected. Our results support propranolol as first-line therapy for complicated infantile hemangiomas. What is Known: • Sleep disorders are frequently reported in infants with infantile hemangiomas treated with propranolol and often lead to treatment discontinuation. • Investigations of the sleep pattern in this patient group using objective measures are lacking. What is New: • The sleep pattern of propranolol-treated infants is assessed using actigraphy and a 24-h sleep diary and compared to healthy, untreated controls. • Propranolol leads to a decreased sleep efficiency at night and an increased demand of daytime sleep, yet effects are mild overall.

Negative pressure wound treatment in a neonate with epidermolysis bullosa simplex severe generalized: A case report.

Negative pressure wound treatment (NPWT) is very useful for the treatment of chronic or deep wounds and in the setting of skin grafting. Due to the need for adhesive dressings, this treatment is rarely attempted in patients with skin fragility secondary to hereditary epidermolysis bullosa (EB). We present a neonate with EB simplex, severe generalized in a critical clinical state where NPWT was successfully applied and describe the measures taken to avoid any further skin damage. This case is of clinical importance to physicians and health care staff treating patients with this rare disease where additional therapeutic measures for the treatment of chronic wounds are scarce.

Checking the basis of intraosseous access-Radiological study on tibial dimensions in the pediatric population.

BACKGROUND: Malposition of intraosseous needles in pediatric patients is frequently reported. Incorrect needle length and penetration depth related to the puncture site and level are possible causes. AIMS: Aim of this study was to analyze anatomic dimensions of the proximal tibia in the pediatric population with respect to intraosseous needle placement and needle tip position. METHODS: Plain lower leg radiographs of children aged from birth to 16 years of age were analyzed. Pretibial tissue layer, cortical bone thickness, and the diameter of the medullary cavity were measured at two different puncture levels. Data were analyzed as descriptive statistics and by polynomial regression plots and set in context to commonly used EZ-IO® needle lengths of 15 and 25 mm. RESULTS: Radiographs from 190 patients (104 boys/86 girls) were included. When fully inserted to skin level, up to 10.5% of needles do not reach medullary cavity at one and 18.5% at two patient's fingerbreadths distal to tibial tuberosity. The opposite cortical wall is touched or penetrated in 16% and 25%, respectively. Up to 96% of too deep needle tip positions occur in children younger than 24 months, as do too superficial tip positions in 59%. CONCLUSIONS: Puncture level and needle length have a great influence on potential needle tip positions. Infants and toddlers are at highest risk for malpositioning. Due to relevant growth-related differences in tibial anatomy, an age-related and well-reflected approach is crucial to successfully establish intraosseous access.

Patient- and Physician-Reported Outcome of Combined Fractional CO2 and Pulse Dye Laser Treatment for Hypertrophic Scars in Children.

BACKGROUND: Hypertrophic scars are commonly seen in children and associated with pruritus, pain, functional impairment, and aesthetic disfigurement. Ablative fractional CO2 and pulse dye laser are emerging techniques to improve scar quality. Only limited data are available on children, nonburn scars, and patient-reported outcome. We aimed to investigate safety and outcome of repeated laser therapy for hypertrophic scars originating from burns and other conditions by means of patient- and physician-reported outcome measures. METHODS: This was a retrospective before-after analysis of laser treatments in children with hypertrophic scars. Outcome was measured using Patient and Observer Scar Assessment Scale, Vancouver Scar Scale and Itch Man Scale. With respect to safety, laser- and anesthesia-related complications were analyzed. RESULTS: Seventeen patients, aged 11.37 ± 4.82 years with 27 scars, underwent 102 distinct laser treatments, mainly combined CO2 and pulse dye laser (94%), with few CO2 only (6%). Vancouver Scar Scale total score before the first and after the first session decreased significantly from 7.65 ± 2.12 to 4.88 ± 1.73; Patient and Observer Scar Assessment Scale observer overall opinion also dropped from 5.88 ± 1.57 to 4.25 ± 1.70. Pruritus improved significantly. Patient age and timing of laser intervention did not have an impact on treatment response. Complications related to laser treatment were seen in 2% (wound infection, n = 2) and to anesthesia in 4% (insignificant n = 2, minor n = 1). CONCLUSIONS: Combined laser therapy significantly improves quality, pain, and pruritus of hypertrophic scars in children. When provided by experienced laser and anesthesia teams, it is safe with a low rate of complications.

Surgical treatment of children and youth with congenital melanocytic nevi: self- and proxy-reported opinions.

PURPOSE: The role of surgery in the management of congenital melanocytic nevi (CMN) is controversial. Data on surgical outcomes and predictors of satisfaction remain scarce. METHODS: An online survey was employed following worldwide recruitment of youth aged 14-25 years (n = 44) and parents of children ≤ 18 years (n = 249) with CMN to query patterns of treatment and satisfaction with and opinions about the benefits of surgery. RESULTS: In proxy-reports, 121 of 249 (49%) and in self-reports 30 of 44 (75%) participants underwent CMN excision. The most common reasons for surgery were psychosocial determinants, aesthetic improvement, and melanoma risk reduction. The overall satisfaction with surgical management was good, although no predictors for satisfaction could be identified. Higher current age of the child was found to predict decision regret in proxy-reports. Most participants indicated that having a scar is more socially acceptable than a CMN. Opinions differed on whether surgery should be deferred until the child is old enough to be involved in the decision-making process. CONCLUSIONS: Whether and when to perform surgery in children with CMN is a multifaceted question. Awareness of common concerns as well as risks and benefits of surgery are essential to ensure critical reflection and balanced decision-making.

A Prospective Controlled Study on Long-Term Outcomes of Facial Lacerations in Children.

Background: Although skin adhesives have been used for decades to treat skin lacerations, uncertainty remains about long-term results, and complications. Methods: In this prospective, controlled, single-blinded, observational cohort study, outcomes were assessed by five plastic surgeons with standardized photographs at 6-12 months using a modified Patient and Observer Scar Assessment Scale (POSAS) and Vancouver Scar Scale (VSS); additionally, the POSAS was performed by the patients/caregivers and the physician; pain, requirement of anesthesia, treatment time, costs, complications, and quality of live (QoL) were assessed. Results: A total of 367 patients were enrolled; 230 were included in the main analysis; 96 wounds were closed using tissue adhesives (group 1); 134 were sutured (group 2). Assessment by the independent observers revealed an improved mean modified overall POSAS score in group 1 in comparison with group 2 [2.1, 95% CI [1.97-2.25] vs. 2.5, 95% CI [2.39-2.63]; p < 0.001, d = 0.58] and mean VSS score [1.2, 95% CI [0.981-1.34] vs. 1.6, 95% CI [1.49-1.79], p < 0.001, d = 0.53]. At the early follow-up, dehiscence rate was 12.5% in group 1 and 3.7% in group 2 (p < 0.001); later on, one dehiscence remained per group. Mild impairment of QoL was found at the early follow-up in both groups, with no impairment remaining later on. Duration of treatment and treatment costs were lower in group 1. Conclusion: Both modalities of wound closure yield favorable esthetic results, and complications are rare. Adhesives are more cost-effective, and its application is less time-consuming; therefore, tissue adhesives offer considerable advantages when used appropriately. Trial Registration: Public trial registration was performed at www.ClinicalTrials.gov (Identifier: NCT03080467).

MR Features of Juxta-Articular Venous Malformations of the Knee to Predict the Clinical Outcome of Sclerotherapy.

PURPOSE: To analyze and correlate preinterventional magnetic resonance (MR) imaging findings with clinical symptoms after percutaneous sclerotherapy of venous malformations (VMs) adjacent to the knee. MATERIALS AND METHODS: Twenty-five patients (mean age, 24 y; range, 7-55 y; 11 female) with 26 VMs adjacent to the knee undergoing sclerotherapy (direct puncture, diagnostic angiography, sclerosant injection) were identified, and MR imaging findings were analyzed. The VM involved the synovium of the knee joint in 19 of 26 cases (76%). These lesions were associated with joint effusion (3 of 19; 16%), hemarthrosis (4 of 19; 21%), or synovial thickening (16 of 19; 84%). Follow-up ended 6-8 weeks after the first or second sclerotherapy session if complete pain relief was achieved or 3 months after the third sclerotherapy session. Treatment outcomes were categorized as symptom improvement (complete or partial pain relief) or poor response (unchanged or increased pain). RESULTS: Forty-nine percutaneous sclerotherapy sessions were performed. Despite the absence of signs of knee osteoarthritis, patients with a VM involving the synovium (8 of 14; 57%) showed a poor response to sclerotherapy (1 of 8 [13%] pain-free after 1 sclerotherapy session). Among patients with VMs with no associated joint alteration and no synovial involvement (6 of 14; 43%), 5 of 6 (83%) showed improvement of symptoms after 1 sclerotherapy session (P < .05). CONCLUSIONS: Juxta-articular VMs of the knee are frequently associated with hemarthrosis and synovial thickening. Patients with signs of osteoarthritis and synovial involvement of the VM on presclerotherapy MR imaging deserve special consideration, as these findings predict worse clinical symptoms after sclerotherapy.

Comparative analysis of functional and aesthetic outcomes of retroauricular full thickness versus plantar glabrous split thickness skin grafts in pediatric palmar hand burns.

BACKGROUND: Optimal management of palmar hand burns in children is controversial. We aimed to compare function and aesthetics of retroauricular full thickness skin grafts (FTSG) to plantar glabrous split thickness skin grafts (STSG). METHODS: 32 palmar grafts in paediatric burn patients were analysed: 19 retroauricular FTSG (group 1) and 13 thick plantar glabrous STSG (group 2). The latter were harvested at a thickness of 0.5 mm. The resulting plantar donor defects were covered with a STSG from the scalp, a sequential surgical technique we termed the "Zurich move". Clinical examination, Cutometer and Colorimeter assessment and validated patient and observer questionnaires were used. Donor site complications and subjective complaints were recorded. RESULTS: Colorimeter results were superior in group 2 with an erythema score of 5.73 ± 2.64 (group 1) versus 2.33 ± 1.97 (group 2, p < 0.001) and a pigmentation score of 9.82 ± 5.42 (group 1) and 1.89 ± 1.92 (group 2, p < 0.001). Observers` scar evaluation using VSS and POSAS showed significantly superior results in group 2 for almost all items. Conversely, group 1 grafts were less stiff with mean normalized tissue extension R0 of 0.80 ± 0.21 versus 0.57 ± 0.24 in group 2 grafts (p < 0.05). In both groups donor sites complications were rare. CONCLUSION: Plantar glabrous STSG showed superior functional and aesthetic results when compared to FTSG in pediatric palmar hand burns. In addition, the "Zurich Move" is safe and provides uncomplicated donor site healing on the scalp and the foot allowing rapid restoration of full function.

Multidisciplinary long-term care and modern surgical treatment of congenital melanocytic nevi - recommendations by the CMN surgery network.

In recent years, our knowledge of congenital melanocytic nevi (CMN) has greatly expanded. This has led to a paradigm shift. The present article represents a commentary by an interdisciplinary group of physicians from German-speaking countries with extensive experience in long-term care and surgical treatment of children and adults with CMN (CMN surgery network, "Netzwerk Nävuschirurgie", NNC). The authors address aspects such as the indication for treatment as well as treatment planning and implementation under these new premises. Adequate counseling of parents on conservative and/or surgical management requires an interdisciplinary exchange among physicians and individualized planning of the intervention, which frequently involves a multi-stage procedure. Today, the long-term aesthetic outcome is at the center of any therapeutic endeavor, whereas melanoma prevention plays only a minor role. The premise of "removal at any cost" no longer holds. Potential treatment-related adverse effects (hospitalization, wound healing disorders, and others) must be carefully weighed against the prospects of a beneficial outcome. In this context, the use of dermabrasion in particular must be critically evaluated. At a meeting of the NNC in September 2018, its members agreed on a consensus-based position on dermabrasion, stating that the procedure frequently leads to impaired wound healing and cosmetically unfavorable or hypertrophic scarring. Moreover, dermabrasion is considered to be commonly associated with considerable repigmentation that usually occurs a number of years after the procedure. In addition, the NNC members saw no benefit in terms of melanoma prevention. In the future, physicians should therefore thoroughly caution about the potential risks and often limited cosmetic benefits of dermabrasion.

Management of congenital melanocytic nevi in the plastic surgery clinic: Families' expectations and their persistent concern about malignancy.

BACKGROUND: Children with congenital melanocytic nevi (CMN) were historically managed with surgical removal to lower the risk of malignant transformation. The evolving literature over the last decade has indicated a significantly lower risk than previously estimated. Indications for excision currently revolve around aesthetic and psychosocial concerns. This study describes and evaluates the perspectives and expectations of patients and families referred to a pediatric plastic surgery clinic on CMN management. METHOD: A two-part questionnaire was administered before and after an initial clinic appointment to evaluate patient and family concerns of lesion growth, risk of malignancy, treatment expectations, and stigmatization. RESULTS: Thirty questionnaires were completed for 11 male and 19 female patients, mean age 9.2 years (1-25). Referring doctors (majority dermatologists) were rarely concerned about malignancy (8%), but parents listed it as a top reason for wanting the CMN removed (37%) and the most common expectation for the visit followed by information about surgical options and outcome. Before the clinic, 93% were at least "slightly" worried about CMN growth and 96% about malignancy, whereas 63% and 72%, respectively, after the clinic. CONCLUSIONS: Families want information about surgical excision and are concerned about malignancy, indicating lingering misinformation or misconception about melanoma risk. For the majority, CMN removal remains at least slightly important, presumably for aesthetic reasons and remaining concern about malignancy. Involved health care professionals should assure reliable and coherent patient information about MM risk, indications for surgery and expected outcome to best support families' decision-making.

A Cultured Autologous Dermo-epidermal Skin Substitute for Full-Thickness Skin Defects: A Phase I, Open, Prospective Clinical Trial in Children.

BACKGROUND: The management of deep partial-thickness and full-thickness skin defects remains a significant challenge. Particularly with massive defects, the current standard treatment, split-thickness skin grafting, is fraught with donor-site limitations and unsatisfactory long-term outcomes. A novel, autologous, bioengineered skin substitute was developed to address this problem. METHODS: To determine whether this skin substitute could safely provide permanent defect coverage, a phase I clinical trial was performed at the University Children's Hospital Zurich. Ten pediatric patients with acute or elective deep partial- or full-thickness skin defects were included. Skin grafts of 49 cm were bioengineered using autologous keratinocytes and fibroblasts isolated from a patient's small skin biopsy specimen (4 cm), incorporated in a collagen hydrogel. RESULTS: Graft take, epithelialization, infection, adverse events, skin quality, and histology were analyzed. Median graft take at 21 days postoperatively was 78 percent (range, 0 to 100 percent). Healed skin substitutes were stable and skin quality was nearly normal. There were four cases of hematoma leading to partial graft loss. Histology at 3 months revealed a well-stratified epidermis and a dermal compartment comparable to native skin. Mean follow-up duration was 15 months. CONCLUSIONS: In the first clinical application of this novel skin substitute, safe coverage of skin defects was achieved. Safety and efficacy phase II trials comparing the novel skin substitute to split-thickness skin grafts are ongoing. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Predictors of Health-related Quality of Life and Psychological Adjustment in Children and Adolescents With Congenital Melanocytic Nevi: Analysis of Parent Reports.

Objectives This cross-sectional study assessed health-related quality of life (HRQOL) and psychological adjustment in children and adolescents affected by congenital melanocytic nevi (CMN) and identified potential predictors of adjustment. Methods Participants were recruited worldwide with the help of patient organizations. Data were obtained from parents of 235 children affected by CMN, aged between 1 month and 18 years (M = 6.3 y; SD = 5.0 y), using a web-based survey. Measures included the Pediatric Quality of Life InventoryTM 4.0 and the Strengths and Difficulties Questionnaire. Sample scores were compared to normative data. Demographic characteristics as well as CMN-related variables were examined as possible predictors of outcome, using multivariate analyses. Results Parents of children and adolescents born with a CMN reported significantly lower HRQOL and somewhat higher emotional and behavioral problems compared to community norms. Impairments in HRQOL and psychological adjustment were predicted by lower socioeconomic status, neurological problems, skin-related discomfort (e.g., itch or pain), and perceived stigmatization. The size of the CMN and whether or not the CMN had been (partially) removed by surgery were no significant predictors. The relationship between visibility of the skin lesion and psychological adjustment and psychosocial health was found to be mediated by perceived stigmatization. Conclusions In children and adolescents affected by CMN, those experiencing neurological problems, skin-related discomfort or high levels of perceived stigmatization are particularly vulnerable for impaired HRQOL and psychological maladjustment and therefore might need special monitoring and support.

Bold to do - bald to be? Outcomes decades after harvesting the scalp in burned children.

BACKGROUND: The scalp is the only hidden donor site for split thickness skin grafts. Nevertheless, it is underappreciated due to fear of iatrogenic scarring alopecia. Long-term data showing whether androgenetic hair loss can reveal previously hidden scarring alopecia is unavailable. We aimed to evaluate results and patient satisfaction up to 30years after skin harvest from the scalp. METHODS: Burn patients, hospitalized between 1977 and 1987 at the University Children's Hospital Zurich with scalp skin harvest and currently over 30years old, were studied. Medical records and patient satisfaction were analyzed, and a clinical scalp examination was performed. RESULTS: Thirty-two patients (18 males, 14 females) with a current age of 34.13±3.42years participated. Mean follow-up time was 27.09±3.04years. Fifty-four scalp harvests were performed with 1.69±0.96 sequential harvests. Hair growth was considered normal in 97% patients. Androgenetic alopecia (AGA) type Norwood II-VI was seen in 11 patients. Scalp examination revealed 11 unknown likely harvest-related alopecias with a mean size of 0.7cm2. CONCLUSIONS: Long-term morbidity of scalp skin harvest and the risk of clinically significant alopecia is very low while patient satisfaction is high. AGA is unlikely to reveal harvest damage previously hidden by regrown hair.
