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.

Tongue Lacerations in Children. The Zurich Tongue Scheme Abstract. Treating injured children is part of everyday life at a pediatrician's office or in an emergency department. Among the most common injuries are lacerations, mainly of the head, but the tongue can also be affected. Lacerations of the tongue mostly occur in early childhood due to fall when the child bites its tongue. No evidence-based treatment recommendations exist, even though such injuries are common. It makes a huge difference to the parents and children affected whether the treatment consists of a primary wound closure in general anesthesia or spontaneous healing can be awaited. In this article, the development and implementation of the Zurich Tongue Scheme will be discussed, the first evidence-based treatment recommendations for uncomplicated tongue lacerations in children.

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.

Longitudinal monitoring and prediction of long-term outcome of scar stiffness on pediatric patients.

BACKGROUND: Hypertrophic scarring after burn injury is one of the greatest unmet challenges in patients with burn injuries. A better understanding of the characteristics of scar maturation and early prediction of the long-term outcome of scarring are prerequisites for improving targeted therapies and pivotal for patient counselling. METHODS: Repeated measurements of scar stiffness in 11 pediatric patients were performed over the course of 1 year using 2 suction devices, the Cutometer and the Nimble. In addition, the observer pliability score of the Patient and Observer Scar Assessment Scale was applied. This longitudinal study allowed quantification of the ability of each of the measured parameters to reflect scar maturation, as indicated by change in skin pliability/stiffness, over time (using linear regression); the ability to distinguish individual patients (intraclass correlation coefficient (ICC)); the correlation of the devices (Spearman correlation coefficient); and the ability to predict long-term scar maturation based on early scar assessment (using receiver operating characteristic). RESULTS: All the tools used showed significant longitudinal decrease of scar stiffness from 3 months until 12 months after the injury. The Nimble (ICCpatient Nimble = 0.99) and the Cutometer (ICCpatient Cuto = 0.97) demonstrated an excellent ability to distinguish between individual patients. The Nimble seemed to be able to predict the 12-month pliability of scars based on early (3-month) measurements (area under the curve (AUC)12m POSAS = 0.67; AUC12m C = 0.46; AUC12m N = 0.79). CONCLUSIONS: The results of this preliminary study suggest that all 3 tools provide suitable means to quantify alterations in scar stiffness over time. Initial evidence suggests the Nimble is most favorable for predicting changes in stiffness associated with long-term scar maturation. Further studies with a larger sample size are required to validate tissue suction as a clinical tool for analysis of changes of scar stiffness over time.

On the Reliability of Suction Measurements for Skin Characterization.

in vivo skin characterization methods were shown to be useful in the detection of microstructural alterations of the dermis due to skin diseases. Specifically, the diagnostic potential of skin suction has been widely explored, yet measurement uncertainties prevented so far its application in clinical assessment. In this work, we analyze specific factors influencing the reliability of suction measurements. We recently proposed a novel suction device, called Nimble, addressing the limitations of existing instruments, and applied it in clinical trials quantifying mechanical differences between healthy skin and scars. Measurements were performed with the commercial device Cutometer and with the new device. A set of new suction measurements was carried out on scar tissue and healthy skin, and FE-based inverse analysis was applied to determine corresponding parameters of a hyperelastic-viscoelastic material model. FE simulations were used to rationalize differences between suction protocols and to analyze specific factors influencing the measurement procedure. Tissue stiffness obtained from Cutometer measurements was significantly higher compared to the one from Nimble measurements, which was shown to be associated with the higher deformation levels in the Cutometer and the nonlinear mechanical response of skin. The effect of the contact force exerted on skin during suction measurements was quantified, along with an analysis of the effectiveness of a corresponding correction procedure. Parametric studies demonstrated the inherently higher sensitivity of displacement- over load-controlled suction measurements, thus rationalizing the superior ability of the Nimble to distinguish between tissues.

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.

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.

Preventive intervention for trauma reactions in young injured children: results of a multi-site randomised controlled trial.

BACKGROUND: Young children are at particular risk for injury. Ten per cent to twenty-five per cent develop posttraumatic stress disorder (PTSD). However, no empirically supported preventive interventions exist. Therefore, this study evaluated the efficacy of a standardised targeted preventive intervention for PTSD in young injured children. METHODS: Injured children (1-6 years) were enrolled in a multi-site parallel-group superiority prospective randomised controlled trial (RCT) in Australia and Switzerland. Screening for PTSD risk occurred 6-8 days postaccident. Parents of children who screened 'high-risk' were randomised to a 2-session CBT-based intervention or treatment-as-usual (TAU). Primary outcomes were PTSD symptom (PTSS) severity, and secondary outcomes were PTSD diagnosis, functional impairment and behavioural difficulties at 3 and 6 months postinjury using blinded assessments. Trials were registered with the Australian New Zealand Clinical Trials Registry (ACTRN12614000325606) and ClinicalTrials.gov (NCT02088814). Trial status is complete. RESULTS: One hundred and thirty-three children screened 'high-risk' were assigned to intervention (n = 62) or TAU (n = 71). Multilevel intention-to-treat analyses revealed a significant intervention effect on PTSS severity over time (b = 60.06, 95% CI: 21.30-98.56). At 3 months, intervention children (M = 11.02, SD = 10.42, range 0-47) showed an accelerated reduction in PTSS severity scores compared to control children (M = 17.30, SD = 13.94, range 0-52; mean difference -6.97, 95% CI: -14.02 to 0.08, p adj. = .055, d = 0.51). On secondary outcomes, multilevel analyses revealed significant treatment effects for PTSD diagnosis, functional impairment and behavioural difficulties. CONCLUSIONS: This multi-site RCT provides promising preliminary evidence for the efficacy of a targeted preventive intervention for accelerating recovery from PTSS in young injured children. This has important clinical implications for the psychological support provided to young children and parents during the acute period following a single-event trauma.

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).

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.

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.

Incidence, severity and pattern of burns in children and adolescents: An epidemiological study among immigrant and Swiss patients in Switzerland.

BACKGROUND: Despite advances in surgical management and critical care for burn surgery, morbidity and mortality of patients with severe burns remains high. Especially in the pediatric population, burns often lead to devastating consequences such as the necessity of corrective surgery until adulthood. Worldwide, 80%-90% of all severe burns occur in low to middle income countries. But also in high income countries, burns are distributed inequitably. Risk factors include age, sex, socioeconomic status, and ethnicity. AIM: The objective of this study was to determine the typical demographics and injury-related data of pediatric burn patients in order to contribute to preventive measures. Special interest was paid to the question of whether the incidence of severe burns is higher among patients with an immigration background. PATIENTS AND METHODS: Patient records of the 4373 patients admitted to the Pediatric Burn Unit of the University Children's Hospital of Zurich from 2006 to 2018 were analyzed. Demographic data and injury patterns are presented descriptively. Temporal trends concerning duration of hospitalization and setting (inpatient versus outpatient), differences in relative incidence and in burn mechanism in distinct cohorts (by nation and Human Development Index (HDI)) and seasonal trends were analyzed. Furthermore, risk factors for large burns and for (prolonged) inpatient treatment were examined using a multivariate approach. RESULTS: Temporal resolution shows considerable variation between inpatient and outpatient treatment (p>0.001) and with shorter hospital stays (p=0.004). Swiss citizens and patients with an immigration background from very highly developed countries sustain a significantly lower incidence of heat-related injuries than all others (p<0.001). The most common burn causes among all children, independent of their country of citizenship, are related to kitchen items or hot tea and coffee (35.57%±4.01% resp. 32.39%±5.95%). Logistic regression revealed that migration background from a low HDI country is significantly associated with larger burns (>5% TBSA) and with a need for inpatient treatment. CONCLUSION: The study emphasizes the need for highly specific measures of burn prevention and indicates the necessity of focusing on certain target groups who are especially vulnerable to burns, such as immigrants from less developed countries.

An effective procedure for skin stiffness measurement to improve Paediatric Burn Care.

BACKGROUND: The objective evaluation of scar quality plays a crucial role in improving burn surgery and scar rehabilitation. Suction-based skin measurements were proposed as a method to objectively determine the mechanical properties of scars, yet their use is limited, in particular for paediatric burn care. A new device was developed which provides essential advantages for scar assessment. The aim of this study was to assess its reliability, intra- and interobserver variability. METHODS: The new device, "Nimble", consists of a lightweight probe that measures the negative pressure needed to obtain a predefined tissue elevation, revealing information on the stiffness of the tissue. 29 former paediatric burn patients were included. Three observers measured the tissue stiffness of a predefined location on the scar and on healthy skin using the Nimble, and the established suction device, the Cutometer®. The reliability of both instruments in distinguishing between healthy skin and scar was assessed by means of the intraclass correlation coefficient. RESULTS: The Nimble successfully differentiated between scar tissue and healthy skin in 92%, the Cutometer in 80% of the patients (p<0.05). Inter- and intraobserver variability of the Nimble (ICCs) were excellent. For the majority of the calculated ICC values the Nimble exceeded the Cutometer®. CONCLUSION: The new device enables reliable and safe measurement of the stiffness of scars. Measurements are less susceptible to patient non-compliance and observer dependency. The Nimble might therefore constitute an easy to use tool for the systematic assessment of scars, thus supporting decision-making in paediatric burn care.

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.

Plastic and Orthopaedic Interventions and Long-Term Sequelae in Children with Meningococcal Septicemia-40 Years of Experience at the University Children's Hospital Zurich.

INTRODUCTION: Meningococcal septicemia is not merely an acute disease with a high lethality, but patients surviving the fulminant phase can suffer from serious long-term sequelae. MATERIALS AND METHODS: The records of 165 patients admitted to the hospital from 1968 to 2008 with the diagnosis of meningococcal septicemia were retrospectively reviewed for early signs at presentation, intensive care management, acute symptoms, the necessity of plastic and orthopaedic surgical management, and long-term orthopaedic sequelae. Possible predictors of these conditions were determined. RESULTS: Overall lethality was 17.5%, and mean time of hospitalization time was 28 days. Integument involvement occurred in 45%, often resulting in the necessity of plastic surgical procedures. Young age is a significant indicator or skin involvement. Amputations were necessary in 9% of all cases, affecting the lower extremities more often than the upper extremities. Six percent of all children suffered from long-term orthopaedic sequelae, such as growth retardation and angular deformities, appearing up to 11 years (mean 4.9 years) after onset of the acute disease. The incidence of amputations and long-term orthopaedic sequelae correlated significantly with severity of the disease. CONCLUSION: Meningococcal septicemia can entail devastating long-term consequences in children surviving the acute phase of the disease. Sequelae may become apparent only years later and cause further damage. To prevent this, a systematic follow-up till adulthood is necessary.

Tongue lacerations in children: to suture or not?

AIMS OF THE STUDY: Tongue lacerations are common in children, occurring mostly from falls or sports injuries. Optimal treatment of tongue lacerations is a challenge for paediatricians due to contradictory recommendations and a lack of current guidelines. It remains unclear which tongue lacerations should be sutured and which would benefit from spontaneous healing, which is a promising alternative. In recent years, the treatment of choice in our paediatric emergency department (ED) has shifted from generally suturing the wounds to more frequently advising secondary wound healing. The aim of this study was to analyse tongue lacerations treated at our ED in order to develop guidance for the optimal management of tongue lacerations in children. METHODS: This retrospective study was conducted to assess tongue lacerations at the ED of a University Children's Hospital Zurich from January 2010 to August 2015. All families were contacted for informed consent and photo documentation of the healed tongue. Clinical records of all the patients included were reviewed and different variables were defined and analysed. RESULTS: A total of 73 children with tongue lacerations were included (75.3% boys, mean age ± standard deviation 4.0 ± 2.6 years). The mean size of the lacerations was 12.4 ± 8.3 mm, with affected tongue borders in 51 cases (69.9%) and a through-and-through laceration in 23 patients (31.5%). A primary wound closure was performed in 12 children (16.4%). These wounds were significantly larger than those of the secondary wound healing group (21 ± 10 mm compared to 10.8 ± 6.8 mm), presented gaping wound edges with the tongue at rest more frequently (91.7% compared to 32.8%), and showed through-and-through lacerations more often (91.7% compared to 19.7%). The group with wound suturing needed longer to recover (median 13 days compared to 6.2 days) and had a higher rate of complications (25 vs 3.3%). CONCLUSIONS: Suturing is not required in gaping tongue lacerations less than 2 cm long that do not involve the tip of the tongue. The Zurich Tongue Scheme was developed as a guide for clinicians when deciding which tongue lacerations need suturing.
