Abstract
BACKGROUND Transport injuries are a major cause of mortality among adolescents. Our aim was to evaluate the circumstances and trauma associated with fatal accidents involving adolescents and two-wheeled vehicles. METHODS We analyzed retrospective data from the Finnish Crash Data Institute from 2008 to 2019 involving 10- to 24-year-old victims of fatal traffic accidents who were injured while riding a bicycle, moped or motorcycle. We collected data on patient characteristics, accident circumstances and possible treatment. These fatalities were compared with national mortality rates among the respective age groups. RESULTS We identified 147 fatalities over the 12-year period involving 20 bicycle, 50 moped and 77 motorcycle riders. Most accidents involved males (n = 121, 82%). Less than half of vehicles were in good condition (46%); motorized vehicles were often illegally tuned (37%) or had tire problems (31%). Most of the accidents were collisions with another vehicle (n = 99, 67%) or other objects (n = 35, 24%). In 94% of cases, the Injury Severity Score was >25. Head injury was the most common cause of death (62%). Among 15-year-olds, every fifth death was due to accidents on two-wheeled vehicles. CONCLUSIONS Fatal transport accidents among adolescents comprise several elements that should be incorporated into driver's education and in case of minors, also communicated to parents. These include the condition of the vehicle, proper helmet use and effects of speed on both control of the vehicle and the consequences of a possible collision.

Abstract
To elaborate expert consensus patient pathways to guide patients and physicians toward efficient diagnostics and management of patients with venous malformations. Methods VASCERN-VASCA (https://vascern.eu/) is a European network of multidisciplinary centers for Vascular Anomalies. The Nominal Group Technique was used to establish the pathways. Two facilitators were identified: one to propose initial discussion points and draw the pathways, and another to chair the discussion. A dermatologist (AD) was chosen as first facilitator due to her specific clinical and research experience. The draft was subsequently discussed within VASCERN-VASCA monthly virtual meetings and annual face-to-face meetings. Results The Pathway starts from the clinical suspicion of a venous type malformation (VM) and lists the clinical characteristics to look for to support this suspicion. Strategies for subsequent imaging and histopathology are suggested. These aim to inform on the diagnosis and to separate the patients into 4 subtypes: (1) sporadic single VMs or (2) multifocal, (3) familial, multifocal, and (4) combined and/or syndromic VMs. The management of each type is detailed in subsequent pages of the pathway, which are color coded to identify sections on (1) clinical evaluations, (2) investigations, (3) treatments, and (4) associated genes. Actions relevant to all types are marked in separate boxes, including when imaging is recommended. When definite diagnoses have been reached, the pathway also points toward disease-specific additional investigations and recommendations for follow up. Options for management are discussed for each subtype, including conservative and invasive treatments, as well as novel molecular therapies. Conclusion The collaborative efforts of VASCERN-VASCA, a network of the 9 Expert Centers, has led to a consensus Diagnostic and Management Pathways for VMs to assist clinicians and patients. It also emphasizes the role of multidisciplinary expert centers in the management of VM patients. This pathway will become available on the VASCERN website (http://vascern.eu/).

Abstract
Background: Sporadic venous malformation (VM) and angiomatosis of soft tissue (AST) are benign, congenital vascular anomalies affecting venous vasculature. Depending on the size and location of the lesion, symptoms vary from motility disturbances to pain and disfigurement. Due to high recurrence of the lesions more effective therapies are needed. Methods: As targeting stromal cells has been an emerging concept in anti-angiogenic therapies, here, by using VM/AST patient samples, RNA-sequencing, cell culture techniques and a xenograft mouse model, we investigated the crosstalk of endothelial cells (EC) and fibroblasts and its effect on vascular lesion growth. Results: We report, for the first time, expression and secretion of transforming growth factor A (TGFA) in ECs or intervascular stromal cells in AST and VM lesions. TGFA induced secretion of VEGF-A paracrinally, and regulated EC proliferation. Oncogenic PIK3CA variant in p.H1047R, a common somatic mutation found in these lesions, increased TGFA expression, enrichment of hallmark hypoxia, and in a mouse xenograft model, lesion size and vascularization. Treatment with afatinib, a pan-ErbB tyrosine-kinase inhibitor, decreased vascularization and lesion size in mouse xenograft model with ECs expressing oncogenic PIK3CA p.H1047R variant and fibroblasts. Conclusions: Based on the data, we suggest that targeting of both intervascular stromal cells and ECs is a potential treatment strategy for vascular lesions having a fibrous component.

Abstract
BACKGROUND Lymphatic malformations (LMs) are benign, congenital lesions that display considerable heterogeneity in terms of size, location and characteristics. This study aims to describe the long-term outcomes of current management strategies for patients with simple (cystic) LMs. METHODS The case records of all patients (age ≤16 years) with simple (cystic) LMs at our tertiary institution between 2008 and 2019 were assessed for clinical features, imaging and details of management, including complications. RESULTS Of a total of 164 patients (60% male), 66% were diagnosed aged <2 years. The median follow-up was 5 (0.3-16) years from diagnosis. LMs were located in the head and neck (40%), extremities (27%), trunk (23%), mediastinum (4%), or intra-abdominally (6%). Types were macrocystic in 47%, microcystic in 21% and mixed in 32%. Sclerotherapy was the most common intervention (38%). Primary surgery had been performed in 12%. Symptomatic improvement, reduction in size, or complete regression were observed in 82/102 (80%) of LMs after interventions; complications from treatment were uncommon (Clavien-Dindo grade I-II: 6%; grade III-IIId: 1%). Sixty-two patients (38%; median age 0.5 (range, 0-12) years) had not required interventions to date; spontaneous regression of the LM occurred in 16 (26%) of these expectantly followed-up cases. CONCLUSIONS Most studies to date have focused on LMs in selected anatomical locations. Herein the outcomes of an entire population from a single tertiary unit of patients are presented, demonstrating the wide heterogeneity of simple (cystic) LMs and highlighting the importance of individualized, multidisciplinary approaches to care in achieving optimal outcomes.

Abstract
INTRODUCTION Obstructive sleep apnoea (OSA) and feeding difficulties are key problems for Pierre Robin sequence (PRS) infants. OSA management varies between treatment centres. Sleep positioning represents the traditional OSA treatment, although its effectiveness remains insufficiently evaluated. DESIGN To complete a polysomnographic (PSG) evaluation of effect of sleep position on OSA in PRS infants less than 3 months of age. We analysed a 10-year national reference centre dataset of 76 PRS infants. PSG was performed as daytime recordings for 67 in the supine, side and prone sleeping position when possible. In most cases, recording included one cycle of non-rapid eye movement (NREM) and rapid eye movement (REM) sleep in each position. RESULTS One-third of infants (9/76, 12%) had severe OSA needing treatment intervention prior to PSG. During PSG, OSA with an obstructive apnoea and hypopnoea index (OAHI) >5 per hour was noted in 82% (55/67) of infants. OSA was most severe in the supine and mildest in the side or in the prone positions. The median OAHI in the supine, side and prone positions were 31, 16 and 19 per hour of sleep (p=0.003). For 68% (52/67) of the infants, either no treatment or positional treatment alone was considered sufficient. CONCLUSIONS The incidence of OSA was 84% (64/76) including the nine infants with severe OSA diagnosed prior to PSG. For the most infants, the OSA was sleep position dependent. Our study results support the use of PSG in the evaluation of OSA and the use of sleep positioning as a part of OSA treatment.

Abstract
INTRODUCTION Road traffic accidents are a major contributor to morbidity and mortality in the pediatric and adolescent population. Among adolescents, bicycles and light motorized two wheelers are popular means of transportation and increase adolescents' autonomy. Most previous studies on injury risk and incidence have pooled different vehicles and age groups together but more distinct data are required to guide policy. MATERIALS AND METHODS We gathered data on all 1,432 children and adolescents (age 7-15) who had been treated for injuries from bicycle(n = 841) or moped/motorized scooter (n = 591) accidents at our study centers during a 6-year period (2008-2013). In addition to clinical data, we reviewed Injury Severity Scores (ISS) and calculated incidence estimates for the population of 15-year-olds in the study area. RESULTS Most bicyclists were injured after a fall (72%), whereas most moped/scooter riders were injured in a collision (51%), most often with a heavier motorized vehicle. Internal injuries, multiple injuries, and severe injuries (ISS >15) were more common among moped/scooter riders than bicyclists (p < 0·001 for all). Moped/scooter riders were more often hospitalized and underwent more operations than bicyclists (p < 0·001 for both). The annual estimated incidence rates of injury were roughly eightfold for 15-year-old moped/scooter riders compared to bicyclists of the same age. CONCLUSION Cycling is in general a safe mode of transportation and rider safety could be further increased with the proper use of helmets. Although no patient deaths occurred in this study population, mopeds and motorized scooters led to significant morbidity.

Abstract
Abstract
Objective
Management of poor response and of long-term complications after bariatric surgery (BS) is complex and under-investigated. Indications and types of reoperations vary widely and postoperative complication rates are higher compared to primary BS. Benchmarking uses best performance in a given field as reference point for improvement. Our aim was to define ‘‘best possible’’ outcomes for elective secondary BS.
Methods
The establishment of benchmarks in secondary BS followed a standardized methodology, based on recommendations of a Delphi consensus panel of experts. This multicenter study analyzed patients undergoing elective secondary BS in 18 high-volume centers on 4 continents from 06/2013 to 05/2019. Twenty-one outcome benchmarks were established in low-risk patients, defined as the 75th percentile of the median outcome values of the centers. Benchmark cases had no: previous laparotomy, diabetes, sleep apnea, cardiopathy, renal insufficiency, inflammatory bowel disease, immunosuppression, history of thromboembolic events, BMI>50kg/m2 or age>65 years. Descriptive statistics, multivariate logistic regression and data visualization were performed using the R software.
Results
Out of 44’884 elective bariatric procedures performed in the participating centers, 5’328 secondary BS cases were identified. The benchmark cohort included 3143 cases, mainly females (85%), aged 43.8±10 years, 8.4±5.3 years after primary BS, with a body mass index 35.2±7kg/m2. Main indications were insufficient weight loss (43%) and gastro-esophageal reflux disease/dysphagia (25%). 90-days postoperatively, 14.57% of benchmark patients presented ≥1 complication, mortality was 0.06% (n = 2). Significantly higher morbidity was observed in non-benchmark cases (OR 1.36) and after conversional or revisional procedures with gastrointestinal suture/stapling (OR 1.7). Benchmark cutoffs at 90-days postoperatively were ≤5.8% re-intervention and ≤8.8% re-operation rate. At 2-years (IQR 1-3) 15.6% of benchmark patients required a reoperation.
Conclusion
Secondary BS is safe, although postoperative morbidity exceeds the established benchmarks for primary BS. The excess morbidity is due to an increased risk of gastrointestinal leakage and higher need for intensive care. The considerable rate of tertiary BS warrants expertise and future research to optimize the management of non-success after BS.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (LRYGB) are both effective surgical procedures to achieve weight reduction in patients with obesity. The trial objective was to merge individual-patient data from two RCTs to compare outcomes after LSG and LRYGB. METHODS Five-year outcomes of the Finnish SLEEVEPASS and Swiss SM-BOSS RCTs comparing LSG with LRYGB were analysed. Both original trials were designed to evaluate weight loss. Additional patient-level data on type 2 diabetes (T2DM), obstructive sleep apnoea, and complications were retrieved. The primary outcome was percentage excess BMI loss (%EBMIL). Secondary predefined outcomes in both trials included total weight loss, remission of co-morbidities, improvement in quality of life (QoL), and overall morbidity. RESULTS At baseline, 228 LSG and 229 LRYGB procedures were performed. Five-year follow-up was available for 199 of 228 patients (87.3 per cent) after LSG and 199 of 229 (87.1 per cent) after LRYGB. Model-based mean estimate of %EBMIL was 7.0 (95 per cent c.i. 3.5 to 10.5) percentage points better after LRYGB than after LSG (62.7 versus 55.5 per cent respectively; P < 0.001). There was no difference in remission of T2DM, obstructive sleep apnoea or QoL improvement; remission for hypertension was better after LRYGB compared with LSG (60.3 versus 44.9 per cent; P = 0.049). The complication rate was higher after LRYGB than LSG (37.2 versus 22.5 per cent; P = 0.001), but there was no difference in mean Comprehensive Complication Index value (30.6 versus 31.0 points; P = 0.859). CONCLUSION Although LRYGB induced greater weight loss and better amelioration of hypertension than LSG, there was no difference in remission of T2DM, obstructive sleep apnoea, or QoL at 5 years. There were more complications after LRYGB, but the individual burden for patients with complications was similar after both operations.

Abstract
Background: Diagnostic work-up of acute appendicitis remains challenging. While some guidelines advise to use a risk stratification based on clinical parameters, others use standard imaging in all patients. As non-operative management of uncomplicated appendicitis has been identified as feasible and safe, differentiation between uncomplicated and complicated appendicitis is of paramount importance. We reviewed the literature to describe the optimal strategy for diagnosis of acute appendicitis. Methods: A narrative review about the diagnosis of acute appendicitis in adult patients was conducted. Both diagnostic strategies and goals were analyzed. Results: For diagnosing acute appendicitis, both ruling in and ruling out the disease are important. Clinical and laboratory findings individually do not suffice, but when combined in a diagnostic score, a better risk prediction can be made for having acute appendicitis. However, for accurate diagnosis imaging seems obligatory in patients suspected for acute appendicitis. Scoring systems combining clinical and imaging features may differentiate between uncomplicated and complicated appendicitis and may enable ruling out complicated appendicitis. Within conservatively treated patients with uncomplicated appendicitis, predictive factors for non-responsiveness to antibiotics and recurrence of appendicitis need to be defined in order to optimize treatment outcomes. Conclusion: Standard imaging increases the diagnostic power for both ruling in and ruling out acute appendicitis. Incorporating imaging features in clinical scoring models may provide better differentiation between uncomplicated and complicated appendicitis. Optimizing patient selection for antibiotic treatment of appendicitis may minimize recurrence rates, resulting in better treatment outcomes.

Abstract
Extensive lymphatic malformations (LMs) of the head and neck region may require tracheostomy to secure the airway. Treatment of these life-threatening LMs is usually multimodal and includes sclerotherapy and surgery, among others. Recently, systemic therapy with sirolimus has been introduced as an effective treatment for venous and lymphatic malformations; its efficacy and safety profile in patients with extensive LM requiring tracheostomy are, however, as yet not fully known. We performed a retrospective, multicenter review and identified 13 patients with an extensive LM of the head and neck region, who previously underwent placement of tracheostomy and subsequently received sirolimus treatment with the aim to improve the local respiratory situation and remove the tracheostomy. Under sirolimus therapy, tracheostomy could be reversed in 8/13 (62%) patients, a further 2/13 (15%) patients improved markedly, and removal of the tracheostomy was planned at the time of writing, while 3/13 (23%) patients showed insufficient or absent response to sirolimus, rendering tracheostomy reversal not feasible. The median duration of sirolimus treatment until removal of tracheostomy was 18 months (range, 8 months to 5.6 years). Adverse events of sirolimus therapy were common [10/13 (77%) patients], yet the majority of these were mild [9/10 (90%) patients] and only one severe adverse event was recorded, with ulceration and necrosis at a catheter insertion site. In conclusion, sirolimus can be considered an effective and safe salvage treatment in patients with extensive LM even after placement of a tracheostomy, as closure of the latter was possible in the majority of patients (62%) of our retrospective cohort. A better understanding of when to start sirolimus therapy, of the duration of treatment, and of factors allowing the prediction of treatment response will require further investigation.

Abstract
BACKGROUND Intra-articular venous malformations of the knee are an uncommon cause of unilateral knee pain in children. Timely diagnosis is important because lesions with intrasynovial involvement can lead to joint space hemorrhage and secondary cartilage damage. OBJECTIVE To describe our tertiary center's experience of diagnostics and typical magnetic resonance imaging (MRI) findings. MATERIALS AND METHODS A retrospective review of all patients ≤16 years of age managed for intra-articular venous malformations of the knee at our institution between 2002 and 2018. RESULTS Of 14 patients (8 male), the mean age at presentation was 6 years (range: 0-14 years). The most common clinical findings were unilateral knee pain (93%), joint swelling (79%), quadriceps atrophy (50%) and a limited range of motion (29%). Cutaneous manifestations were present in four patients (29%). Contrast-enhanced MRI was available in all cases. After initial MRI, a vascular anomaly etiology had been identified in 11 cases (79%), and correctly reported as a venous malformation in 6 (55%). Three patients received entirely different diagnoses (arthritis, tumor or pigmented villonodular synovitis). Three of seven patients with intrasynovial lesions had established chondropathy at diagnosis. Two patients with lesions of the suprapatellar fat pad had intrasynovial involvement that was not visualised on MRI. CONCLUSION Although MRI usually permits the diagnosis, clinical awareness of these lesions is important for optimal imaging, accurate interpretation and timely diagnosis. Involvement of the intrasynovial cavity carries a risk of hemarthrosis and progressive chondropathy that may be underestimated by MRI.

Abstract
BACKGROUND Based on epidemiological and clinical data acute appendicitis can present either as uncomplicated (70-80%) or complicated (20-30%) disease. Recent studies have shown that antibiotic therapy is both safe and cost-effective for a CT-scan confirmed uncomplicated acute appendicitis. However, based on the study protocols to ensure patient safety, these randomised studies used mainly broad-spectrum intravenous antibiotics requiring additional hospital resources and prolonged hospital stay. As we now know that antibiotic therapy for uncomplicated acute appendicitis is feasible and safe, further studies evaluating optimisation of the antibiotic treatment regarding both antibiotic spectrum and shorter hospital stay are needed to evaluate antibiotics as the first-line treatment for uncomplicated acute appendicitis. METHODS APPAC II trial is a multicentre, open-label, non-inferiority randomised controlled trial comparing per oral (p.o.) antibiotic monotherapy with intravenous (i.v.) antibiotic therapy followed by p.o. antibiotics in the treatment of CT-scan confirmed uncomplicated acute appendicitis. Adult patients with CT-scan diagnosed uncomplicated acute appendicitis will be enrolled in nine Finnish hospitals. The intended sample size is 552 patients. Primary endpoint is the success of the randomised treatment, defined as resolution of acute appendicitis resulting in discharge from the hospital without the need for surgical intervention and no recurrent appendicitis during one-year follow-up. Secondary endpoints include post-intervention complications, late recurrence of acute appendicitis after one year, duration of hospital stay, pain, quality of life, sick leave and treatment costs. Primary endpoint will be evaluated in two stages: point estimates with 95% confidence interval (CI) will be calculated for both groups and proportion difference between groups with 95% CI will be calculated and evaluated based on 6 percentage point non-inferiority margin. DISCUSSION To our knowledge, APPAC II trial is the first randomised controlled trial comparing per oral antibiotic monotherapy with intravenous antibiotic therapy continued by per oral antibiotics in the treatment of uncomplicated acute appendicitis. The APPAC II trial aims to add clinical evidence on the debated role of antibiotics as the first-line treatment for a CT-confirmed uncomplicated acute appendicitis as well as to optimise the non-operative treatment for uncomplicated acute appendicitis.

Abstract
PURPOSE To assess if postponing surgery of paediatric supracondylar humerus fractures (SCHF) without compromised blood circulation to office hours can improve the quality of reduction and pin fixation and decrease complications. METHODS In 2004, night-time (0am to 7am) surgery was allowed only for children with compromised blood circulation. Number of open reductions, surgeons experience, operation time, quality of reduction (Baumann angle, anterior humeral line crossing point with capitellum) and pin fixation as well as the number of complications were compared in 100 children before (A) and 100 after (B) the new protocol. Surgery was commenced during office hours (8am to 3pm) in 27% (A) versus 55% (B) and delay to surgery from admission exceeded six hours in 25% (A) versus 52% (B) of the children. RESULTS Open reduction was performed in eight (A) versus 11 (B) children. In group A, 40% were operated on by a registrar alone compared with 14% in group B. Mean operation room time decreased by 11 minutes in group B. Radiographic alignment was satisfactory at fracture union in 68% (A) versus 68% (B) and radiologically stable pin fixation in 42% (A) versus 55% (B) of children (p = 0.08). The was no statistical difference in admission time, re-reductions, infections, permanent iatrogenic nerve injuries or corrective osteotomies between the patient groups. CONCLUSIONS No statistical difference in quality of reduction or pin fixation or in number of complications was observed. Postponing operative treatment of SCHF without vascular compromise increased consultant attendance in operations and decreased operative room time. LEVEL OF EVIDENCE III - retrospective comparative study.

Abstract
BACKGROUND: Kick scooters are popular among children in both transportation and recreational activities. The aim of this retrospective study was to assess the incidence of and injury patterns associated with kick scooter accidents in school-aged children and adolescents. METHODS: All 171 patients at the age of 7-15 years who were treated for kick scooter-related injuries in the metropolitan Helsinki area, Southern Finland from January 2008 to December 2013 were included. Electronic medical records were reviewed and Pediatric Trauma Scores and Injury Severity Scores were utilized to assess the injuries. RESULTS: The annual number of patients increased from 7 in 2008 to 55 in 2013. Almost all patients (94%, n = 161) were injured after a fall from their own height. Most patients (n = 118; 69%) were diagnosed with a fracture but only 26 patients (15%) required surgical procedures under general anesthesia. Pediatric Trauma Scores were low and only one patient had an Injury Severity Score > 15 which can be considered major trauma. CONCLUSION: Most injuries acquired from kick scooter injuries were easily treatable fractures and bruises. Considering the background population of 105,000 in the respective age group and the 6-year period of data collection from tertiary care, scooting seems a safe means of increasing the physical activity levels of school-aged children and adolescents.

Abstract
Background and Aims: To assess the accuracy of computed tomography in diagnosing acute appendicitis with a special reference to radiologist experience. Material and Methods: Data were collected prospectively in our randomized controlled trial comparing surgery and antibiotic treatment for uncomplicated acute appendicitis (APPAC trial, NCT01022567). We evaluated 1065 patients who underwent computed tomography for suspected appendicitis. The on-call radiologist preoperatively analyzed these computed tomography images. In this study, the radiologists were divided into experienced (consultants) and inexperienced (residents) ones, and the comparison of interpretations was made between these two radiologist groups. Results: Out of the 1065 patients, 714 had acute appendicitis and 351 had other or no diagnosis on computed tomography. There were 700 true-positive, 327 true-negative, 14 false-positive, and 24 false-negative cases. The sensitivity and the specificity of computed tomography were 96.7% (95% confidence interval, 95.1–97.8) and 95.9% (95% confidence interval, 93.2–97.5), respectively. The rate of false computed tomography diagnosis was 4.2% for experienced consultant radiologists and 2.2% for inexperienced resident radiologists (p = 0.071). Thus, the experience of the radiologist had no effect on the accuracy of computed tomography diagnosis. Conclusion: The accuracy of computed tomography in diagnosing acute appendicitis was high. The experience of the radiologist did not improve the diagnostic accuracy. The results emphasize the role of computed tomography as an accurate modality in daily routine diagnostics for acute appendicitis in all clinical emergency settings.

Abstract
BACKGROUND An increasing amount of evidence supports antibiotic therapy for treating uncomplicated acute appendicitis. The objective of this study was to compare the costs of antibiotics alone versus appendicectomy in treating uncomplicated acute appendicitis within the randomized controlled APPAC (APPendicitis ACuta) trial. METHODS The APPAC multicentre, non-inferiority RCT was conducted on patients with CT-confirmed uncomplicated acute appendicitis. Patients were assigned randomly to appendicectomy or antibiotic treatment. All costs were recorded, whether generated by the initial visit and subsequent treatment or possible recurrent appendicitis during the 1-year follow-up. The cost estimates were based on cost levels for the year 2012. RESULTS Some 273 patients were assigned to the appendicectomy group and 257 to antibiotic treatment. Most patients randomized to antibiotic treatment did not require appendicectomy during the 1-year follow-up. In the operative group, overall societal costs (€5989·2, 95 per cent c.i. 5787·3 to 6191·1) were 1·6 times higher (€2244·8, 1940·5 to 2549·1) than those in the antibiotic group (€3744·4, 3514·6 to 3974·2). In both groups, productivity losses represented a slightly higher proportion of overall societal costs than all treatment costs together, with diagnostics and medicines having a minor role. Those in the operative group were prescribed significantly more sick leave than those in the antibiotic group (mean(s.d.) 17·0(8·3) (95 per cent c.i. 16·0 to 18·0) versus 9·2(6·9) (8·3 to 10·0) days respectively; P < 0·001). When the age and sex of the patient as well as the hospital were controlled for simultaneously, the operative treatment generated significantly more costs in all models. CONCLUSION Patients receiving antibiotic therapy for uncomplicated appendicitis incurred lower costs than those who had surgery.

Abstract
BACKGROUND AND OBJECTIVE Infantile hemangioma (IH) includes, among its other risk factors, familial clustering, but a definitive understanding of IH's inheritance model and genetic basis is lacking. Our objective was to collect IH pedigrees in Finland, to study the inheritance patterns of IH within these families, and to analyze the characteristics of familial IHs. METHODS We identified 185 patients with IH who visited our vascular anomaly clinic between 2004 and 2007. Based on hospital records and a questionnaire sent to these patients and their families, IH characteristics and family history of IH were studied. We compared characteristics between patients with positive (familial) and negative (sporadic) IH family history. Families with positive IH family history were further interviewed for extended pedigree data. RESULTS One-third of our IH cohort's families reported a family history positive for IH, with IH characteristics and perinatal data between the familial and sporadic cases being similar. IH patients with affected first-degree relatives reported higher long-term discomfort rates than the sporadic cases. Of the 40 families interviewed, 11 included ≥4 IH-affected family members; these were most commonly first-degree relatives (63%). Segregation patterns match with autosomal dominant inheritance with an incomplete penetrance or maternal transmission. We also present a case of monozygotic twins that manifest identical IHs. CONCLUSIONS Based on this large number of IH pedigrees, we suggest at least 2 possible mechanisms of inheritance: autosomal dominant and maternal transmission. This study highlights the need for additional genetic studies to define inheritance of this common disease.

Abstract
Background We aimed to improve management of extremity low-flow vascular malformations by analyzing the histology and imaging of venous malformations (VMs) not responsive to sclerotherapy. Method We reviewed patient records of 102 consecutive patients treated with sclerotherapy for extremity VM in our institution to identify patients who had undergone surgery due to insufficient response. We semi-quantitatively analysed the tissue specimens and compared histological findings to those in preoperative imaging. Result The number of patients operated on was 19 (18.6%); 15 of them had lower-extremity intramuscular lesions. The histological pattern of 13 of these 15 lesions corresponded to angiomatosis of soft tissue (AST). All other lesions treated surgically were VMs. The histology of AST was distinctive but magnetic resonance imaging findings often overlapped with those of VM. Conclusion AST is easily mixed with intramuscular VM. The differentiation of these two entities has therapeutic importance. We emphasize the role of histology in the differential diagnostics of intramuscular slow-flow vascular malformations.

Abstract
Positron emission tomography (PET) studies suggest opioidergic system dysfunction in morbid obesity, while evidence for the role of the dopaminergic system is less consistent. Whether opioid dysfunction represents a state or trait in obesity remains unresolved, but could be assessed in obese subjects undergoing weight loss. Here we measured brain μ-opioid receptor (MOR) and dopamine D2 receptor (D2R) availability in 16 morbidly obese women twice-before and 6 months after bariatric surgery-using PET with [(11)C]carfentanil and [(11)C]raclopride. Data were compared with those from 14 lean control subjects. Receptor-binding potentials (BPND) were compared between the groups and between the pre- and postoperative scans among the obese subjects. Brain MOR availability was initially lower among obese subjects, but weight loss (mean=26.1 kg, s.d.=7.6 kg) reversed this and resulted in ~23% higher MOR availability in the postoperative versus preoperative scan. Changes were observed in areas implicated in reward processing, including ventral striatum, insula, amygdala and thalamus (P's<0.005). Weight loss did not influence D2R availability in any brain region. Taken together, the endogenous opioid system plays an important role in the pathophysiology of human obesity. Because bariatric surgery and concomitant weight loss recover downregulated MOR availability, lowered MOR availability is associated with an obese phenotype and may mediate excessive energy uptake. Our results highlight that understanding the opioidergic contribution to overeating is critical for developing new treatments for obesity.

Abstract
AIM We identified the characteristics of an infantile haemangioma (IH) that predispose children to complications, interventions and long-term morbidity and examined perinatal risk factors for IH. METHODS We studied children with IHs admitted to Helsinki University Hospital's paediatric vascular anomaly clinic in Finland in 2004-2007 and registered perinatal records, IH characteristics, complications and interventions. These patients received a questionnaire on perinatal data and long-term morbidity resulting from IH. We analysed factors related to complications, interventions and morbidity and compared our cohort's perinatal data to the Finnish Medical Birth Register (FMBR) figures. RESULTS We approached 185 families, of which 136 replied to the questionnaire. Children with facial, segmental and indeterminate IHs showed more complications, interventions and higher long-term morbidity. Preterm birth predisposed infants to ulceration of IHs, with a 95% confidence interval (CI) of 1.02-5.14 and odds ratio (OR) of 2.29. In addition to earlier known risks, maternal gestational diabetes mellitus rate was higher in our IH cohort than the rate in the FMBR (95% CI 1.39-4.95, OR 2.62). CONCLUSION Physicians treating IHs should consider the elevated ulceration risk in preterm infants. The association between gestational diabetes mellitus and child's risk for an IH is uncertain and requires further research.

Abstract
Background Sclerotherapy is often the primary treatment for peripheral venous malformations. It is mostly sufficient alone, but can be combined with other endovascular techniques. Despite its mini-invasiveness, it is not without potentially severe complications. Here, we systematically report sclerotherapy complications in trunk and extremity venous malformations. Methods We retrospectively assessed the complications of 127 consecutive patients who had received sclerotherapy for peripheral venous malformation in our tertiary care unit (January 2007-August 2013). We applied the Clavien-Dindo classification to grade the severity of complications. We mostly used detergent sclerosants (85.7%), and less often ethanol (5.7%) or bleomycin (4.2%). In 4.2% of the procedures, we combined glue, coils, endovascular laser or particles to sclerotherapy. Results The overall complication rate per procedure was 12.5%. Most complications (83.3%) were local and managed conservatively. We encountered four severe complications, all related to blood coagulopathy. Subcutaneous lesion location and use of ethanol significantly increased the risk of local complications. Conclusion Sclerotherapy alone or combined with other endovascular techniques is a safe method for local venous malformations with moderate risk for conservatively manageable complications. Blood coagulopathy constitutes a risk for, otherwise rare, severe complications.

Abstract
It is well known that the law of a Brownian motion started from x > 0 and conditioned never to hit 0 is identical with the law of a three-dimensional Bessel process started from x. Here we show that a similar description is valid for all linear Ornstein–Uhlenbeck Brownian motions. Further, using the same techniques, it is seen that we may construct a non-stationary Ornstein–Uhlenbeck process from a stationary one.

Abstract
BACKGROUND AND AIMS In our previous study, the annual number of adolescents treated at Helsinki Children's Hospital and Töölö Trauma Centre for injuries from moped and scooter accidents increased five-fold between 2002 and 2007. In June 2011, the requirements for a moped/scooter license changed to include driver's education and a vehicle handling evaluation. The aim of this retrospective study was to assess the influence of legislative changes on moped and scooter related serious injuries in adolescents. PATIENTS AND METHODS Data from 520 patients (age 15-16) treated for trauma from moped and scooter accidents at our institutions between January 2008 and December 2013 were included. Case numbers were compared with population data from national databases. Overall incidence, trauma mechanism, injury profile, and proportion of patients requiring hospital admission were calculated for time periods before and after the law amendment. RESULTS After the law change in 2011, the annual incidence of moped/scooter injuries among 15-year-olds in our area decreased from 0.8% in 2011 to 0.3% in 2013 (p<0.001), and estimated incidence of injuries per new moped/scooter license declined from 1.8% in 2011 to 1.0% in 2013 (p=0.001). Simultaneously, proportions of patients injured in collisions, diagnosed with multiple trauma or requiring in-patient care reduced. CONCLUSIONS A change in moped/scooter license requirements may have a causal relationship with both reduced number and severity of moped/scooter related injuries in adolescents.

Abstract
AIM Patients with vascular anomalies are often misdiagnosed, leading to delayed or improper treatment. The aim of this study was to evaluate the impact of an interdisciplinary team on the diagnosis and treatment of paediatric patients with vascular anomalies. METHODS We reviewed the paediatric patients evaluated by our interdisciplinary team between 2002 and 2012, analysing the referral diagnosis, final diagnosis, patient age, sex, clinical history, laboratory tests, imaging studies and treatments. RESULTS Of the 480 patients who were evaluated, 435 (90.6%) had a vascular anomaly: 30.7% of all patients had a tumour and 55.2% had a malformation. Haemangiomas comprised 93.2% of all tumours, while malformations included capillary (9.8%), lymphatic (30.1%), venous (36.8%), arteriovenous (3.8%) and combined slow-flow (7.9%) malformations. Tumours were initially diagnosed correctly in 89.2% of the patients, but only 38.0% of the malformations were diagnosed correctly. Improper treatment was given to 1.4%, due to incorrect diagnoses. CONCLUSION This study showed that haemangiomas were likely to be diagnosed correctly, but other tumours and vascular malformations were likely to be misdiagnosed. Misdiagnosis seldom led to improper treatment, but probably led to delayed treatment in many cases. The interdisciplinary approach led to improved diagnostics and treatment.

Abstract
BACKGROUNDS Second branchial cleft anomalies predispose to recurrent infections, and surgical resection is recommended as the treatment of choice. There is no clear consensus regarding the timing or surgical technique in the operative treatment of these anomalies. Our aim was to compare the effect of age and operative techniques to patient characteristics and treatment outcome. METHODS A retrospective study of pediatric patients treated for second branchial sinuses or fistulae during 1998-2012 at two departments in our academic tertiary care referral center. Comparison of patient characteristics, preoperative investigations, surgical techniques and postoperative sequelae. RESULTS Our data is based on 68 patients, the largest series in the literature. One-fourth (24%) of patients had any infectious symptoms prior to operative treatment. Patient demographics, preoperative investigations, use of methylene blue, or tonsillectomy had no effect on the surgical outcome. There were no re-operations due to residual disease. Three complications were observed postoperatively. CONCLUSIONS Our patient series of second branchial cleft sinuses/fistulae is the largest so far and enables analyses of patient characteristics and surgical outcomes more reliably than previously. Preoperative symptoms are infrequent and mild. There was no difference in clinical outcome between the observed departments. Performing ipsilateral tonsillectomy gave no outcome benefits. The operation may be delayed to an age of approximately three years when anesthesiological risks are and possible harms are best avoided. Considering postoperative pain and risk of postoperative hemorrhage a routine tonsillectomy should not be included to the operative treatment of second branchial cleft fistulae.

Abstract
BACKGROUND AND AIMS The long-term efficacy of laparoscopic Roux-en-Y gastric bypass in the treatment of morbid obesity has already been demonstrated. Laparoscopic sleeve gastrectomy has shown promising short-term results, but the long-term efficacy is still unclear. The aim of this prospective randomized multicenter study is to compare the results of Roux-en-Y gastric bypass and sleeve gastrectomy. MATERIAL AND METHODS A total of 240 morbidly obese patients were randomized to undergo either Roux-en-Y gastric bypass or sleeve gastrectomy. The primary end point of study was weight loss, and the secondary end points were resolution of comorbidities and morbidity. The short-term results at 6 months were analyzed. RESULTS The mean excess weight loss at 6 months was 49.2% in the sleeve gastrectomy group and 52.9% in the Roux-en-Y gastric bypass group (p = 0.086). Type 2 diabetes was resolved or improved in 84.3% of patients in the sleeve gastrectomy group and 93.3% in the Roux-en-Y gastric bypass group (p = 0.585). The corresponding results for arterial hypertension were 76.8% and 81.9% (p = 0.707) and for hypercholesterolemia 64.1% and 69.0% (p = 0.485). There was no mortality at 6 months. There was one major complication following sleeve gastrectomy and two after Roux-en-Y gastric bypass (p = 0.531). Eight sleeve gastrectomy patients and 11 Roux-en-Y gastric bypass patients had minor complications (p = 0.403). CONCLUSION The short-term results of sleeve gastrectomy and Roux-en-Y gastric bypass regarding weight loss, resolution of obesity-related comorbidities and complications were not different at 6 months.

Abstract
Esophageal perforation is associated with significant mortality, and this may markedly increase with advanced age. This multicenter study investigates this issue in patients older than 80 years. Data on 33 patients >80 years old who underwent conservative (10 patients), endoclip (one patient), stent grafting (11 patients), or surgical treatment (11 patients) for esophageal perforation were collected from nine centers. Surgical repair consisted of repair on drain in one patient, primary repair in seven patients, and esophagectomy in two patients. Among patients who underwent stent grafting, one required repeat stenting and another stent graft repositioning. One patient was converted to surgical repair after stent grafting. Thirteen patients (39.4%) died during the 30-day and/or in-hospital stay. Their mortality was significantly higher than in a series of patients<80 years old (13.0%, 21/161 patients, P=0.001). Three patients (30.0%) died after conservative treatment, one (100%) after treatment with endoclips, five (45.5%) after stent grafting, and four (36.4%) after surgical repair (P=0.548). Early survival with salvaged esophagus was 42.4% (conservative treatment: 70.0% endoclips 0%, stent grafting: 54.5%, and surgical repair: 54.5%, respectively, P=0.558). Estimated glomerular filtration rate<60 mL/minute/1.73 m2 (70.0% vs. 25.0%, P=0.043) and sepsis (100% vs. 32.1%, P=0.049) at presentation were associated with increased risk of early mortality in univariate analysis. Esophageal perforation in octogenarians is associated with very high early and intermediate high mortality irrespective of the treatment method used.

Abstract
AIMS/HYPOTHESIS The role of the intestine in the pathogenesis of metabolic diseases is gaining much attention. We therefore sought to validate, using an animal model, the use of positron emission tomography (PET) in the estimation of intestinal glucose uptake (GU), and thereafter to test whether intestinal insulin-stimulated GU is altered in morbidly obese compared with healthy human participants. METHODS In the validation study, pigs were imaged using [(18)F]fluorodeoxyglucose ([(18)F]FDG) and the image-derived data were compared with corresponding ex vivo measurements in tissue samples and with arterial-venous differences in glucose and [(18)F]FDG levels. In the clinical study, GU was measured in different regions of the intestine in lean (n = 8) and morbidly obese (n = 8) humans at baseline and during euglycaemic hyperinsulinaemia. RESULTS PET- and ex vivo-derived intestinal values were strongly correlated and most of the fluorine-18-derived radioactivity was accumulated in the mucosal layer of the gut wall. In the gut wall of pigs, insulin promoted GU as determined by PET, the arterial-venous balance or autoradiography. In lean human participants, insulin increased GU from the circulation in the duodenum (from 1.3 ± 0.6 to 3.1 ± 1.1 μmol [100 g](-1) min(-1), p < 0.05) and in the jejunum (from 1.1 ± 0.7 to 3.0 ± 1.5 μmol [100 g](-1) min(-1), p < 0.05). Obese participants failed to show any increase in insulin-stimulated GU compared with fasting values (NS). CONCLUSIONS/INTERPRETATION Intestinal GU can be quantified in vivo by [(18)F]FDG PET. Intestinal insulin resistance occurs in obesity before the deterioration of systemic glucose tolerance.

Abstract
Despite multiple previous studies in the field of vascular anomalies, the mechanism(s) leading to their development, progression and maintenance has remained unclear. In this study, we have characterized the expression levels of vascular endothelial growth factors and their receptors in 33 human vascular anomalies. Analysis with quantitative real-time PCR and gene-specific assays showed higher expression of neuropilin-2 (NRP2) and VEGF-receptor-3 (VEGFR-3) mRNAs in vascular malformations (VascM) as compared to infantile hemangiomas (Hem). In addition, the expression levels of PlGF and VEGF-C mRNA were significantly higher in venous VascM when compared to the other VascM and Hem. Higher expression of NRP2 and VEGFR-3 were confirmed by immunohistochemistry. To further study the importance of NRP2 and VEGFR-3, endothelial cell (EC) cultures were established from vascular anomalies. It was found that NRP2 and VEGFR-3 mRNA levels were significantly higher in some of the VascM ECs as compared to human umbilical vein ECs which were used as control cells in the study. Furthermore, adenoviral delivery of soluble decoy NRP2 prevented the proliferation of ECs isolated from most of the vascular anomalies. Our findings suggest that NRP2 functions as a factor maintaining the pathological vascular network in these anomalies. Thus, NRP2 could become a potential therapeutic target for the diagnosis and treatment of vascular anomalies.

Abstract
BACKGROUND AND PURPOSE Peripheral AVM is a locally aggressive disease with a high tendency to recur; its treatment is complex, especially in the anatomically delicate head and neck area. Here, we report results of ethanol sclerotherapy for head and neck AVM and discuss its potential use for peripheral AVM. MATERIALS AND METHODS We retrospectively assessed degree of AVM eradication, complications, and clinical or imaging signs of recurrence for 19 patients treated with ethanol sclerotherapy for head and neck AVM (1 intraosseous, 18 soft-tissue AVMs). RESULTS Of the 19 patients, 11 had complete eradication of arteriovenous shunting at DSA, with 1 recurrence (mean follow-up 15 months), and for 7 patients, treatment is ongoing. During 59 treatment sessions, 12 patients experienced 14 complications, 1 leading to permanent functional damage. CONCLUSIONS Ethanol sclerotherapy has potential for complete eradication of head and neck AVM with low recurrence within the first year after completion of treatment. Complete eradication may require several treatment sessions during which complications should be minimized with careful techniques.

Abstract
Hemangioma is the most common benign tumor in infancy. Over 90% of hemangiomas require no treatment, but there is a need to recognize those that may require even quick measures to secure vital functions or normal development of organs. Propranolol has established itself as the first-line treatment. Pulsed dye laser has proven effective in the treatment of ulcerated hemangiomas. Corticosteroid therapy is applied only rarely, but surgical treatment or angiography and embolization therapy associated with it may sometimes be indicated.

Abstract
OBJECTIVE Capsule endoscopy (CE) offers noninvasive methods to assess small bowel pathology but only limited data are available on the feasibility, safety, and findings in children. In this study, we report our results of 100 consecutive CE in children. MATERIAL AND METHODS Single center retrospective study. All pediatric patients (mean age 119 months, range from 8 to 188 months) undergoing CE were included until 100 investigations were completed. The indications for CE were: suspicion or evaluation of Crohn's disease (n = 35) or ulcerative colitis (n = 24), gastrointestinal bleeding (n = 18), and miscellaneous (n = 23). RESULTS The youngest patients able to swallow the capsule were 84 months old. When the patient was unable to swallow the capsule (n = 51), it was guided into the duodenum with endoscope. In two patients, the capsule remained in the stomach during the 8 h of recording and in 23 cases the capsule failed to reach the cecum. The capsule was expelled naturally in all except one patient. In 39% of the patients, CE revealed a significant finding (multiple ulcers, bleeding, tumors, strictures). In patients examined for bleeding or for a suspicion of Crohn's disease, the respective proportions were 50% and 60%. CONCLUSIONS This study shows that CE is a feasible diagnostic method to study the small intestine in pediatric patients and that CE can be done in children as young as 8 months old. The diagnostic yield is highest in cases with bleeding or a high suspicion of Crohn's disease.

Abstract
AIM Conventional outcomes such as survival, tumour recurrence and complication rates after surgery for rectal cancer have been rigorously assessed, but the importance of maintaining quality of life (QOL) after surgery for rectal cancer has received less attention. The aim of the current study was to analyse QOL and the occurrence of pelvic dysfunction after the surgical treatment of rectal cancer. METHOD Between May 2005 and May 2008, 150 patients with rectal cancer underwent abdominoperineal resection (APR) or anterior resection (AR). Seventy-four answered two preoperative questionnaires. At a follow up of 1 year, 65 were alive without sign of recurrence and answered the same questionnaires: (a) validated RAND 36-item health survey QOL questionnaire; and (b) self-administered disease-related questionnaire with special reference to anorectal and urogenital function. RESULTS The postoperative general QOL was similar after surgery, and mental functioning was better (P < 0.001). Problems with physical functions were associated with anal dysfunction after AR (P < 0.001) and problems with social functioning were associated with urinary dysfunction (P = 0.038). At 1 year after surgery, urinary incontinence was worse (P = 0.026) after all operations, and the incidence of dysuria was higher after APR than AR (P = 0.001). Male sexual function also worsened (P = 0.060). Anorectal dysfunction caused more inconvenience among patients who underwent AR (P = 0.028). Preoperative radiation was associated with postoperative ejaculation problems (P = 0.028) and anal incontinence (P = 0.012). CONCLUSION Factors affecting QOL and pelvic floor function should be taken into account when making treatment decisions in rectal cancer.

Abstract
BACKGROUND The surgical treatment of gastroesophageal reflux-induced reflux laryngitis remains controversial. The aim of this study was to determine both long-term objective endoscopic findings and subjective symptomatic outcomes after laparoscopic Nissen fundoplication in patients operated on for reflux laryngitis. METHODS 40 consecutive patients with pH-proven reflux laryngitis underwent laparoscopic Nissen fundoplication between 1998 and 2002. 68% (n = 27) of these patients underwent an endoscopic evaluation and 90% (n = 36) were available for the subjective long-term outcome (personal interviews). RESULTS At a median follow-up of 91 months there were no disrupted plications, none of the patients had esophagitis but 3 recurrent hiatal hernias were detected. 61% of the patients reported no or only mild reflux laryngitis symptoms postoperatively and 69% of the patients evaluated their voice quality improved after surgery. 94% of the patients were satisfied with their surgical result. With benefit of hindsight, 11% of the patients would not choose surgical treatment and 42% had reinitiated antireflux medications postoperatively. CONCLUSION The majority of pH-proven gastroesophageal reflux-induced reflux laryngitis patients attain long-term symptomatic benefit and satisfaction on the surgical outcome, and with proper patient selection laparoscopic Nissen fundoplication provides a feasible long-term treatment option for reflux laryngitis.

Abstract
The electric solar wind sail (E-sail) is a space propulsion concept that uses the natural solar wind dynamic pressure for producing spacecraft thrust. In its baseline form, the E-sail consists of a number of long, thin, conducting, and centrifugally stretched tethers, which are kept in a high positive potential by an onboard electron gun. The concept gains its efficiency from the fact that the effective sail area, i.e., the potential structure of the tethers, can be millions of times larger than the physical area of the thin tethers wires, which offsets the fact that the dynamic pressure of the solar wind is very weak. Indeed, according to the most recent published estimates, an E-sail of 1 N thrust and 100 kg mass could be built in the rather near future, providing a revolutionary level of propulsive performance (specific acceleration) for travel in the solar system. Here we give a review of the ongoing technical development work of the E-sail, covering tether construction, overall mechanical design alternatives, guidance and navigation strategies, and dynamical and orbital simulations.

Abstract
Systemic immune responses after OK-432 (Picibanil) sclerotherapy in patients with head and neck lymphatic malformations (LM) were examined to achieve a better understanding of the mechanism of OK-432 sclerotherapy and to evaluate the long-term treatment outcome. Serum samples from 17 consecutive patients with head and neck LMs were collected during a total of 26 OK-432 treatment episodes. Serum C-reactive protein (CRP), interleukins (IL) 1β, 6, 8, 10, tumor necrosis factor (TNF)-α, interferon (IFN)-γ, RANTES, immune protein (IP)-10 and macrophage chemoattractant protein (MCP)-1 as well as blood leukocyte counts were determined. Clinical outcome of the treatment was evaluated at the last visit and from patient files. Elevated serum levels of IP-10 (means at baseline 702 ng/L, after 1 day 1180 ng/L, after 4 weeks 691 ng/L) were seen on day one after OK-432 sclerotherapy (p < 0.05). C-reactive protein and leukocyte counts 1 day after treatment differed statistically significantly (p < 0.05) from the baseline. No significant differences with other cytokines investigated were observed. Patients with macrocystic LM responded better than patients with microcystic LM (p = 0.01). The elevated levels of IP-10, C-reactive protein and leukocyte levels indicate that OK-432 sclerotherapy induces systemic immune responses in patients with LM. The mechanisms of OK-432 sclerotherapy are still not precisely understood, but the IP-10 elevation may reflect local antiangiogenetic properties of immunoactivation induced by OK-432.

Abstract
BACKGROUND Laparoscopic Nissen fundoplication has become the method of choice in antireflux surgery replacing its open counterpart before the long-term results of controlled clinical trials were available. METHODS AND AIM: Review of the literature to highlight the long-term results of laparoscopic Nissen fundoplication. RESULTS Long-term symptom relief regarding significant reflux symptoms of heartburn and regurgitation can be achieved by laparoscopic fundoplication in 84% to 97% and patients' overall satisfaction with the result of their laparoscopic fundoplication surgery is high, ranging from 86% to 96%. The long-term results of randomised trials have shown no statistically significant differences in subjective symptomatic outcome between laparoscopic and open Nissen fundoplication. Complaints regarding the scar, incisional hernias and higher incidence of defective wraps were associated with the open approach. CONCLUSION At long-term follow-up the laparoscopic Nissen fundoplication has a similar long-term subjective symptomatic outcome as the open procedure but laparoscopic Nissen fundoplication is associated with a significantly lower incidence of incisional hernias and defective fundic wraps at endoscopy, defining laparoscopic Nissen fundoplication as the procedure of choice in surgical management of gastro-oesophageal reflux disease.

Abstract
Background and Aims: Mopeds and scooters have become increasingly popular among Finnish teenagers. The aim of this retrospective study was to assess incidence of and injury patterns associated with moped and scooter accidents in adolescents. Materials and Methods: All 222 patients treated for moped and scooter-related injuries at Helsinki Children's Hospital and Töölö Trauma Centre from January 2002 to December 2007 were included. Information was drawn from patient records and compared with nation-wide Finnish data gathered from public data-bases. Results: The annual number of patients at our centres increased from 14 to 76 and the proportion of girls increased from 7% to 25%. A similar trend was found on a national level. In our material, collisions between mopeds and other motorized vehicles accounted for 52% of accidents, and 33% of patients were injured from falling. Seventy-five percent of patients were hospitalized, and 50% needed at least one procedure requiring general anaesthesia. Five percent of the patients were under the influence of alcohol. Trauma of the head occurred in 22%; helmets did not protect against severe trauma. On a national level the proportion of 15- to 17-year-old road traffic victims has doubled in five years. Among this age group, more than half of all road-traffic accidents involve mopeds and scooters. Conclusions: Over a time span of six years, moped accidents among adolescents have become very common. Our results suggest that measures should be taken to diminish the number of moped and scooter accidents and to improve driver safety.

Abstract
BACKGROUND Esophageal perforations and extensive anastomotic leaks after esophageal resection or gastrectomy are surgical emergencies with high mortality rates. In recent years, the use of self-expanding metallic stents (SEMS) has emerged as a promising treatment alternative for bridging and sealing the damage. This study aimed to evaluate the role of covered SEMS for the management of esophageal perforations and anastomotic leaks. METHODS All esophageal stent placement procedures (174 procedures for 157 patients) at the authors' unit between January 1999 and April 2008 were assessed by a retrospective chart review. Of the 157 patients, 10 (6.4%) were treated with SEMS for sealing of an iatrogenic esophageal perforation (n = 4), a spontaneous esophageal rupture in Boerhaave's syndrome (n = 4), or an anastomotic leakage (n = 2). RESULTS The median time from perforation or anastomotic leak to stent insertion was 13 days (range, 2 h to 48 days). The esophageal leak was totally sealed for 8 (80%) of 10 patients. The overall mortality rate was 50% (n = 5), and three (30%) of the five deaths were related to the perforation (n = 2) or leakage (n = 1). In both of the perforation cases, the diagnosis and treatment were substantially delayed. One patient with an anastomotic leak after gastrectomy died of the complication despite successful operative and SEMS treatment. Two of the deaths were unrelated to the perforation. In both cases, the cause of death was a disseminated malignant disease. CONCLUSIONS Traumatic perforations and anastomotic leaks can be treated effectively with covered SEMS together with adequate drainage of the thoracic cavity even in cases of severely ill patients with inveterate esophageal perforations and leaks.

Abstract
Nasal glial heterotopia (nasal glioma) is a rare congenital malformation of neural origin. We present a newborn baby with life-threatening respiratory distress secondary to nasopharyngeal glial heterotopia that obstructed the nasopharyngeal or nasal airway. A high degree of suspicion, early diagnosis and surgical management are essential to cure this rare and potentially life-threatening disorder.

Abstract
BACKGROUND AND STUDY AIMS The majority of recent large series on endoscopic retrograde cholangiopancreatography (ERCP) complications have been multicenter studies reflecting varying degrees of experience and ERCP volume; major ERCP complications are associated with low case volume. The aim of this study was to report and analyze the frequency of severe and fatal complications associated with ERCP at a single specialized surgical high-volume referral center (Turku University Central Hospital). METHODS All scheduled ERCP procedures (n = 2788) at our unit between January 1997 and December 2005 were included and the procedure-related severe and fatal complications were assessed by retrospective chart review. Complications were classified as severe or fatal according to standardized guidelines. RESULTS The number of ERCP procedures performed was 2555, of which 71% were therapeutic and 29% were diagnostic. Seventeen (0.8%) severe complications were identified in 16 patients, of whom 15 underwent a therapeutic endoscopic procedure. Of the 17 severe complications, perforation constituted five cases (0.2%), pancreatitis occurred in five patients (0.2%), bleeding in five cases (0.2%), and two patients suffered from purulent cholangitis (0.1%). Procedure-related mortality was 0.08% (n = 3). CONCLUSIONS In our study the rate of severe or fatal complications of ERCP is low in experienced hands at a high-volume center, comparing favorably to corresponding complication rates of multicenter series, which further supports the importance of centralizing ERCP procedures in high-volume advanced centers.

Abstract
BACKGROUND The adverse outcomes of laparoscopic fundoplication are more likely during the initial 20 cases performed by each individual surgeon. This study aimed to evaluate the impact of substantial surgical experience versus experience beyond the learning curve on the early and late objective and subjective results. METHODS The patients were divided into two groups according to the surgeon. In group 1 (n = 230), all the patients underwent surgery by a surgeon with substantial experience in laparoscopic fundoplication. In group 2 (n = 118), the patients were treated by a total of seven surgeons whose personal experience exceeded the individual learning curve, but was distinctively less than that of the group 1 surgeon. RESULTS The conversion rate was 2.2% in group 1 and 4.4% in group 2. The median operating time was 65 min in group 1 and 70 min in group 2 (p = 0.0020). The occurrence of immediate complications was 3.5% in group 1 and 7.6% in group 2 (p = 0.0892). At 6 months after surgery, 7.4% of the patients in group 1 and 16.1% of the patients in group 2 reported that dysphagia disturbed their daily lives (p = 0.0115). The late subjective results, including postoperative symptoms and evaluation of the surgical result, were similar in the two groups. CONCLUSIONS Substantial experience with the procedure is associated with a shorter operating time and somewhat fewer complications, conversions, and early dysphagia episodes. This supports the provision of expert supervision even after the initial learning phase of 20 individual procedures. The patients' long-term subjective symptomatic outcome was similar in the two groups. Substantial experience does not provide better late results than surgical experience beyond the learning curve.

Abstract
After creation of open or percutaneous endoscopic gastrostomy, gastric prolapse and leak of gastric contents may cause serious skin rash and infection which are often difficult to treat. We present four patients in whom these problems were solved with gastrostomy revision by a modified Janeway 'gastric tube' technique. The patients were aged 7 months and 7, 10 and 16 years at the time of the revision. The underlying conditions were hypoxic encephalopathy with epilepsy, infantile spasm and epilepsy with arthrogryposis, dystonic tetraplegy, and total colon aganglionosis. All patients had gastrostomy prolapse with peristomal skin rash and cellulitis. Prior to modified Janeway revision, the four patients had undergone a total of 16 failed attempts to cure the prolapse. At the operation, the previous gastrostomy was detached and closed. A longitudinal gastric tube of 6 cm was created along the greater curvature with a GIA stapler and brought through the abdominal wall leaving 3-5 cm of free intra-abdominal gastric tube. A balloon catheter was left for 6 weeks, and replaced with a long Mickey tube according to patient's or caretaker's preference. There were no surgical complications. Hospitalisation after revision was median 6 (range 4-11) days. Six weeks after the revision, prolapse, leak and peristomal infections were cured in all patients, and feeding through the gastrostomy presented no problems. One patient underwent minor excision of excess stomal mucosa. Two patients opted for Mickey tube, two for a feeding catheter. A median of 9 (6-16) months after the revision, all patients have a functioning gastrostomy without prolapse or leak. Modified Janeway 'gastric tube' revision is feasible and, within short to medium term follow-up, controls efficiently gastrostomy prolapse and leak.
