Education is a central determinant of adolescent health. School absences and bullying involvement jeopardize educational attainment. We analyzed time trends in school absenteeism over two decades and examined the association of absenteeism with bullying involvement. We analyzed data from the nationwide School Health Promotion study, with self-reported data from Finnish middle school students in grades 8 and 9 (ages 14–17, N = 1 000 970). Questionnaires assessed frequency of illness absences (IA), truancy, frequency of bullying victimization (BV), bullying perpetration (BP), and involvement in both bullying perpetration and victimization (BPV). Frequent school absences were defined as occurring at more than 3 days during the prior month (2000–2015), or least weekly (2017–2019). Frequent IA increased from 12% in 2000 to 22% in 2015. In 2017–2019 frequent IA was reported by 3.5%. Frequent truancy declined from 9% in 2000 to 4% in 2015, and 2017–2019. BV was reported at least weekly by 6.9%, BP by 5.4% and BVP by 1.9% of participants. In a logistic regression model, all kinds of bullying involvement increased odds for both IA and truancy. Since bullying involvement was associated with both IA and truancy, particular concern should be raised for adolescents involved in bullying, and for their social and educational functioning. The concurrent increase in IA and decrease in truancy may reflect destigmatization of mental health problems or other changing patterns in reporting absenteeism.

ObjectiveTo determine whether the timing of puberty associates with school performance.MethodsGrowth data on 13,183 children born between 1997 and 2002, were collected from child health clinics and school healthcare and school performance data from school records. Age at peak height velocity (PHV) marked pubertal timing. The relationships between age at PHV and average grades in mathematics, native language, English, and physical education from school years 6 (end of elementary school; age 11-12 years), 7 (start of middle school; 12-13 years), and 9 (end of middle school; 14-15 years) were modeled using generalized estimating equations and linear mixed models, adjusted for the month of birth and annual income and education levels in school catchment areas.ResultsThe mean (SD) age at PHV was 13.54 (1.17) years in boys and 11.43 (1.18) years in girls. In girls, age at PHV was associated with grades in mathematics (β=0.041–0.062, pConclusionsIn both sexes, the timing of puberty was associated with the grades in physical education, and in girls, with academic achievement. The decrease in boys’ mathematics grades and sex difference in academic achievement were unexplained by the timing of puberty.

AimTo evaluate differences in menstrual and pubertal history and trends in eating behaviours among women with and without a competitive sports background. Additionally, we investigated if menstrual history and eating behaviours are associated with sports career-related factors.MethodsThis retrospective study was conducted on 100 women with a competitive endurance sports background and their age-matched, gender-matched and municipality-matched controls (n=98). Data were collected using a questionnaire using previously validated instruments. Generalised estimating equations were used to calculate associations of menstrual history and eating behaviours with outcome variables (career length, participation level, injury-related harms and career termination due to injury).ResultsAthletes reported higher rates of delayed puberty and menstrual dysfunction than controls. No differences between the groups were observed in the Eating Disorder Examination Questionnaire short form (EDE-QS) scores at any age. Previous disordered eating (DE) was associated with current DE in both groups. Among athletes, higher EDE-QS scores during the sports career were associated with a shorter career (B=−0.15, 95% CI −0.26 to –0.05). Secondary amenorrhoea was associated with lower participation level (OR 0.51, 95% CI 0.27 to 0.95), injury-related harms during the career (OR 4.00, 95% CI 1.88 to 8.48) and career termination due to injury (OR 1.89, 95% CI 1.02 to 3.51).ConclusionThe findings indicate that DE behaviours and menstrual dysfunction, specifically secondary amenorrhoea, have a disadvantageous relationship with a sports career in women competing in endurance sports. DE during the sports career is associated with DE after the career.

Background Self-harm in very young people can be a clinically ominous event. While most studies to date have focused on self-harm during the teenage years, fewer studies have examined children aged 12 years or under. We aimed to estimate the incidence and correlates of recent self-harm in a population-based, non-treatment-seeking sample of primary school-aged children. Methods 1059 children from 43 primary schools in Melbourne, Australia were interviewed at the age of 8 years (Wave 1), and followed up annually until the age of 11 years (Waves 2-4). Interviews covered a range of physical and mental health, social, educational and family domains, including (at Wave 4) self-harm during the previous 12 months. Results At Wave 4 (mean age: 11.9 years), a total of 28 children (3%; 18 girls [3%], 10 boys [2%]) reported self-harming during the previous 12 months. When compared with children who reported no self-harm, they were more likely to report depression, anxiety, poor emotional control, frequent bullying victimisation (including online bullying), truancy, recent alcohol consumption, and antisocial behaviour during Waves 1-3. They were also more likely to report having few friends. Conclusions Self-harm was reported by a proportion of community-dwelling children aged 11-12 years. As these children were more likely to report a range of other adverse behaviours, experiences and health conditions, clinicians should consider the possibility of prior self-harm when assessing children presenting with such behaviours and issues. Key messages The focus of intervention efforts aimed at preventing and reducing adolescent self-harm should extend to primary school-aged children, with a focus on mental health and peer relationships during the pubertal transition.

Purpose of the studySchool absenteeism and school dropout jeopardize the future health and wellbeing of students. Reports on the participation of school health care in absenteeism reduction are infrequent, although physical and mental health problems are the most common causes of school absenteeism. Our aim was to explore what reasons different professionals working in schools recognize for absenteeism and which factors either promote or inhibit the inclusion of school health care in absenteeism reduction.Materials and methodsData for this qualitative study was gathered from ten focus groups conducted in two municipalities in southern Finland. The groups included (vice) principals, special education/resource/subject teachers, guidance counselors, school social workers, school psychologists, school nurses, school doctors, and social workers working in child protective services. Data analysis was predominantly inductive but the categorization of our results was based on existing literature.ResultsStudy participants identified student-, family-, and school-related reasons for absenteeism but societal reasons went unmentioned. A number of reasons promoting the inclusion of school health care in absenteeism reduction arose, such as expertise in health-related issues and the confidentiality associated with health care. Inclusion of school health care was hindered by differences in work culture and differing perceptions regarding the aims of school health care.ConclusionProfessionals working in schools were knowledgeable about the different causes of school absenteeism. Clarifying both the aims of school health care and the work culture of different professionals could facilitate the inclusion of school health care in absenteeism reduction.

Background Unexplained graft fibrosis and inflammation are common after pediatric liver transplantation (LT). Objective We investigated the graft expression of fibrogenic genes and correlated the findings with transplant histopathology and outcome. Methods Liver biopsies from 29 recipients were obtained at a median of 13.1 (IQR: 5.0-18.4) years after pediatric LT. Control samples were from six liver-healthy subjects. Hepatic expression of 40 fibrosis-related genes was correlated to histological findings: normal histology, fibrosis with no inflammation, and fibrosis with inflammation. Liver function was evaluated after a subsequent follow-up of 9.0 years (IQR: 8.0-9.4). Results Patients with fibrosis and no inflammation had significantly increased gene expression of profibrotic TGF-beta 3 (1.17 vs. 1.02 p = .005), CTGF (1.64 vs. 0.66 p = .014), PDGF-alpha (1.79 vs. 0.98 p = .049), PDGF -beta (0.99 vs. 0.76 p = .006), integrin-subunit-beta 1 (1.19 vs. 1.02 p = .045), alpha-SMA (1.12 vs. 0.58 p = .013), type I collagen (0.82 vs. 0.53 p = .005) and antifibrotic decorin (1.15 vs. 0.99 p = .045) compared to patients with normal histology. mRNA expression of VEGF A (0.84 vs. 1.06 p = .049) was lower. Only a few of the studied genes were upregulated in patients with both fibrosis and inflammation. The gene expression levels showed no association with later graft outcome. Conclusions Altered hepatic expression of fibrosis-related genes is associated with graft fibrosis without concurrent inflammation.

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 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.

Objectives: Across diagnosis groups, successful transition of adolescent and young adults from children's hospitals to adult care is often associated with decreased treatment adherence and treatment results. The aim of this study was to characterize disease activity and anti-rheumatic medications following transfer of care of juvenile idiopathic arthritis (JIA) patients to the adult clinic.Method: All consecutive JIA patients aged 16-20 years who visited the specific transition clinic in the rheumatology outpatient clinic of Helsinki University Hospital between November 2012 and May 2013 and between April 2015 and April 2016 were evaluated.Results: A total of 214 patients were identified, and 23 appeared in both cohorts. Females had higher disease activity scores (DAS) than males (DAS28-CRP 1.90.7 versus 1.6 +/- 0.3, p=.019; and DAS44-CRP 1.0 +/- 0.7 versus 0.7 +/- 0.5, p=.005; respectively) in the latter cohort. Disease-modifying antirheumatic drugs (DMARDs) were prescribed to 86% of patients, and 48% were on biological DMARDs (bDMARDs), whereas 14% had no specific treatments.Conclusion: Disease activity and clinic attendance remained stable during the transition period. The proportion of transition phase JIA patients on bDMARDs was high and disease activity was low. Reasons for lower disease activity in males in the latter cohort require further investigation.

Despite the frequency of pain among children, little is known about its effects on learning and school outcomes. The objective of this study was to quantify the association of pain and academic achievement while taking into account the presence of co-occurring emotional symptoms. A population-based stratified random sample of 1239 students aged 8 to 9 years from primary schools in Melbourne, Australia, was recruited for the Childhood to Adolescence Transition Study. Children indicated sites of pain that had lasted for a day or longer in the past month using a pain manikin. Depressive- and anxiety-related symptoms were assessed using child-reported items. National assessment results for reading and numeracy were used to measure academic achievement. Sixty-five percent of children reported pain in at least 1 body site and 16% reported chronic pain. Increasing number of pain sites was associated with poorer reading scores in a dose-response fashion (β = -3.1; 95% confidence interval -4.9 to -1.3; P < 0.001). The association was only partly attenuated when adjusting for emotional symptoms (β = -2.6; 95% confidence interval -4.5 to -0.8; P < 0.001) and was not moderated by emotional symptoms. Children with chronic pain were a year behind their peers in both reading and numeracy. Among primary school students, pain was associated with lower reading scores even after adjusting for the presence of emotional symptoms. Although population-based longitudinal studies will be required to ascertain consistency and possible causality, grounds exist for considering pain and emotional symptoms in the assessment of children with reading difficulties.

OBJECTIVES The aim of the study was to evaluate health-related quality of life (HRQoL) and parental distress in a national cohort of children with biliary atresia (BA) with their native livers in relation to BA complications and HRQoL of normal population controls. METHODS We invited all Finnish children with BA surviving with their native livers at age 2 to 18 years to participate in 2009 and in 2014. Parents filled the Pediatric Quality of Life Inventory (PedsQL) proxy questionnaire, a survey of their child's health and evaluated parental distress on a visual-analog scale from 0 to 7. Overall participation rates were 80% (12/15) for the longitudinal and 83% (20/24) for the cross-sectional assessment. A control population of 324 children matched for age and sex was randomly picked, and 108 (33%) participated. RESULTS Overall, patients and controls had comparable HRQoL. Patients reported significantly lower scores for school functioning (P = 0.004) as depicted by missing school or day care due to hospital visits. Eighty-five percent of parents reported extreme worry (7.0) when hearing their child's BA diagnosis. At 6 years after diagnosis, parents reported significantly less worry: median score 3.8 (interquartile range 3.0-5.4, P

To define digital health services that have been studied among chronically ill adolescents and to describe e-health coaching elements that may have an impact on transition outcomes.Systematic review without meta-analysis.MEDLINE (Ovid), Pub Med, Scopus and CINAHL on 28 May 2018.Peer-reviewed articles published between January 2008-May 2018 were reviewed following the Cochrane Handbook for Systematic Reviews of Interventions and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement.Twelve randomized controlled trials were included. The interventions varied significantly in duration and content. E-coaching that included human and social support showed positive impact on transition outcomes. Digital health services incorporated into usual care provide efficient and accessible care.E-coaching elements enable tailoring and personalization and present a tool for supporting and motivating chronically ill adolescents during transition of care. Future research should evaluate the effectiveness of e-coaching elements.Digital services are considered a means for increasing adolescents' motivation for self-care and for increasing their accessibility to health care. The coaching elements in digital services consist of a theoretical basis, human support, interactive means and social support. Included interventions varied in terms of duration, dose, content and design. Our results may serve the development of digital health services for adolescents in transition. E-coaching can be used to engage and motivate chronically ill adolescents to improve health behaviour and self-management during transition of care.目的: 明确已开展研究的针对患有慢性病青少年的数字化医疗服务,并说明可能影响过渡结果的电子医疗指导要素。 设计: 不包括荟萃分析的系统评估。 数据来源: 于2018年5月28日通过MEDLINE(Ovid)、Pub Med、Scopus和CINAHL数据库进行检索。 评估方法: 对于2008年1月至2018年5月期间发表的同行评审文章按照《Cochrane干预措施系统评价手册》的要求进行评估,并根据《系统评估和荟萃分析优先报告条目》进行报告。 结果: 共纳入12项随机对照试验。干预措施在持续时间和内容方面存在显著差异。包括人力和社会支持在内的电子指导对过渡结果产生了积极影响。将数字化医疗服务用于日常护理有助于提供高效便利的护理工作。 结论: 电子指导要素可实现个性化定制服务,并提供了一个在护理过渡期为患有慢性病青少年提供支持和激励的工具。今后的研究应注重评估电子指导要素的有效性。 影响: 数字化服务被认为是增强青少年自我护理动力以及增加他们获得医疗护理机会的一种手段。数字化服务中的指导要素包括理论基础、人力支持、互动方式和社会支持。同时还包括在持续时间、剂量、内容和设计方面各不相同的干预措施。我们的研究结果可为针对过渡期青少年发展数字化医疗服务提供一定帮助。电子指导可用于促使并激励患有慢性病青少年在护理过渡期改善健康行为,进行自我管理。.

Background and aims: In our previous study, the annual number of adolescents treated at Helsinki Children's Hospital and Toolo 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

IntroductionThe effects of electronic media use on health has received much attention but less is known about links with academic performance. This study prospectively examines the effect of media use on academic performance in late childhood.Materials and methods1239 8- to 9-year-olds and their parents were recruited to take part in a prospective, longitudinal study. Academic performance was measured on a national achievement test at baseline and 10-11 years of age. Parents reported on their child's duration of electronic media use.ResultsAfter control for baseline reading, watching more than two hours of television per day at 8-9 years of age predicted a 12-point lower performance in reading at 10-11 years, equivalent to the loss of a third of a year in learning. Using a computer for more than one hour a day predicted a similar 12-point lower numeracy performance. Regarding cross-sectional associations (presumed to capture short-term effects) of media use on numeracy, after controlling for prior media exposure, watching more than two hours of television per day at 10-11 years was concurrently associated with a 12-point lower numeracy score and using a computer for more than one hour per day with a 13-point lower numeracy performance. There was little evidence for concurrent effects on reading. There was no evidence of short- or long-term associations between videogame use and academic performance.DiscussionCumulative television use is associated with poor reading and cumulative computer use with poorer numeracy. Beyond any links between heavy media use and health risks such as obesity, physical activity and mental health, these findings raise a possibility of additional risks of both television and computer use for learning in mid-childhood. These findings carry implications for parents, teachers and clinicians to consider the type and timing of media exposure in developing media plans for children.

Across diagnosis groups, transition of adolescents and young adults from children’s hospitals to adult care associates with decreased treatment adherence and suboptimal treatment results. Our aim was to compare the health-related quality of life (HRQoL) and disease activity of juvenile idiopathic arthritis (JIA) patients after the transfer of care to the adult clinic and adult patients in the same outpatient clinic. All consecutive JIA patients aged 16 to 20 years who visited the transition clinic between September 2016 and August 2017 and all consecutive adult onset arthritis patients between December 2016 and August 2017 in the rheumatology outpatient clinic of Helsinki University Hospital were evaluated. HRQoL was measured by a generic instrument, 15D. A total of 291 patients, 130 JIA, and 161 adults were identified with respective median disease durations of 6.5 and 4.0 years. Adults had lower HRQoL measured by 15D (median 0.90 vs. 0.96, P

Background School health services provide an excellent opportunity for the detection and treatment of children at risk of later health problems. However, the optimal use of school doctors’ skills and expertise remains unknown. Furthermore, no validated method for screening children for school doctors’ assessments exists. The aims of the study are 1) to evaluate the benefits or harm of school doctors’ routine health checks in primary school grades 1 and 5 (at ages 7 and 11) and 2) to explore whether some of the school doctors’ routine health checks can be omitted using study questionnaires. Methods This is a prospective, multicenter observational study conducted in four urban municipalities in Southern Finland by comparing the need for a school doctor’s assessment to the benefit gained from it. We will recruit a random sample of 1050 children from 21 schools from primary school grades 1 and 5. Before the school doctor’s health check, parents, nurses and teachers fill a study questionnaire to identify any potential concerns about each child. Doctors, blinded to the questionnaire responses, complete an electronic report after the appointment, including given instructions and follow-up plans. The child, parent, doctor and researchers assess the benefit of the health check. The researchers compare the need for a doctor’s appointment to the benefit gained from it. At one year after the health check, we will analyze the implementation of the doctors’ interventions and follow-up plans. Discussion The study will increase our knowledge of the benefits of school doctors’ routine health checks and assess the developed screening method. We hypothesize that targeting the health checks to the children in greatest need would increase the quality of school health services.

Half of adult liver transplantation (LT) recipients develop metabolic syndrome, but the prevalence after childhood LT remains unknown. We conducted a national cross-sectional study of all living patients who had undergone LT between 1987 and 2007 at an age less than 18 years. We gathered information on blood pressure, body composition, serum lipids, glucose metabolism, and histological liver fat content. The diagnostic criteria for metabolic syndrome of the American Heart Association and the International Diabetes Federation were used. After a median post-LT follow-up time of 12 years, half of all patients had no components of metabolic syndrome. The prevalence of overweight/obesity was 20%, and the prevalence of hypertension was 24%. Serum triglycerides were high in 9%, and high-density lipoprotein levels were low in 23%. Fasting glucose levels were impaired in 14%, but none had diabetes. Altogether, 9 patients (14%) had metabolic syndrome. Moderate liver steatosis found in protocol liver biopsy samples was associated with the accumulation of metabolic syndrome features (P = 0.01). No significant associations were found between immunosuppressive medications and metabolic syndrome. In conclusion, the prevalence of metabolic syndrome after childhood LT is similar to the prevalence in the general population of the same age. Guidelines for the general population, therefore, seem valid for the prevention and treatment of metabolic syndrome after pediatric LT as well. Liver Transpl 20:1185–1192, 2014. © 2014 AASLD.

Hepatic artery thrombosis (HAT) after liver transplantation (LT) increases patient morbidity and mortality. Early HAT is considered to occur within the first month after LT, whereas late HAT occurs after the first month. Few studies have addressed late HAT after LT, especially in pediatric patients. Between 1987 and 2007, 99 patients (age

Adolescents with a kidney transplant (KT) require special attention during the transition of care. Few longitudinal studies have assessed the effect of transition models (TM) on patient outcomes. Between 1986 and 2013, 239 pediatric patients underwent KT in Finland, of whom 132 have been transferred to adult care. In 2005, a TM was developed following international recommendations. We compared patient (PS) and graft survival (GS) rates before and after the introduction of the TM. PS and GS at 10 years were similar before and after the implementation of the TM (PS 85% and 90% respectively, P = 0.626; GS 60% and 58%, respectively, P = 0.656). GS was lower in patients transplanted at age 10-18 than in patients transplanted at a younger age in the TM cohort (79% vs 95%, P < 0.001). During the first five years after transfer, 63% of patients had stable KT function, 13% had deteriorating function and 24% lost their KT. Altogether 32 out of 132 patients lost their kidney allograft within five years after transfer to adult care (13 before and 19 after TM implementation, P = 0.566). The implementation of this TM had no effect on PS or GS. Further measures to improve our TM are in progress.

Controversy remains about the role of protocol liver biopsy for symptom-free recipients and about the long-term use of low-dose steroids after pediatric liver transplantation (LT). We conducted a national cross-sectional study of pediatric recipients who underwent LT between 1987 and 2007. Liver biopsy samples were taken from 54 patients (82% of survivors) after a median posttransplant follow-up of 11 years, and they were reviewed by 2 pathologists blinded to the clinical data. Biopsy samples from 18 patients (33%) showed nearly normal histology with no inflammation, fibrosis, or steatosis. Portal inflammation was detected in 14 samples (26%), showed no correlation with anti-nuclear antibodies, and was less frequent in the 35 patients whose immunosuppression included steroids (14% versus 47% of patients not using steroids, P = 0.008). Fibrosis was present in 21 biopsy samples (39%). According to the Metavir classification, 16 were stage 1, 3 were stage 2, and 2 were stage 3. The fibrosis stage correlated negatively with serum prealbumin levels (r = -0.364, P = 0.007) and positively with chronic cholestasis (cytokeratin 7 staining; r = 0.529, P < 0.001) and portal inflammation (r = 0.350, P = 0.01). Microvesicular steatosis was found in 23 biopsy samples (43% of patients in 5%-80% of hepatocytes), and it correlated with the body mass index (r = 0.458, P < 0.001) but not with steroid use. The age of the allograft (donor age plus follow-up time) correlated with higher serum gamma-glutamyltransferase (r = 0.472, P < 0.001) and conjugated bilirubin levels (r = 0.420, P = 0.002) as well as chronic cholestasis (r = 0.299, P = 0.03). The biopsy findings led to treatment changes in 10 patients (19%), whereas only 1 complication (subcapsular hematoma) was encountered. In conclusion, continuing low-dose steroids indefinitely after pediatric LT may have a positive effect on the long-term histological state of the liver graft. Allograft aging may lead to chronic cholestasis and thus contribute to the development of liver fibrosis.

Evidence-based recommendations on endoscopic screening and prophylactic treatment of esophageal varices in patients with biliary atresia (BA) are scarce. We assessed the efficiency of endoscopic surveillance and risk factors of esophageal varices and associated upper gastrointestinal bleeding.A total of 47 consecutive children with BA and portoenterostomy underwent yearly endoscopies and prophylactic injection sclerotherapy of esophageal varices between 1987 and 2009. The median follow-up was 1.7 years (range 0.5-18.9) and overall 2-year survival 71%. Disease characteristics, clearance of jaundice, laboratory tests reflecting liver function and hypersplenism, as well as sonographic signs of portal hypertension were related to endoscopic findings and bleeding episodes.Grade 2 to 3 varices developed with similar frequency after failed (18/28, 64%) and successful portoenterostomy (10/19, 53%) in 28 patients. Following failed portoenterostomy, esophageal varices were encountered significantly earlier (8 [4-23] vs. 19 [4-165] months, P = 0.004), and they reappeared after eradication more often (16/16 vs. 4/10, P = 0.001). Varices bled only after failed portoenterostomy (13/28 vs. 0/19, P 0.001). Increased serum bilirubin concentration40 μmol/L at 3 months after portoenterostomy was a risk factor of upper gastrointestinal bleeding (odds ratio [OR] 17, 95% confidence interval [CI] 1.7-175, P = 0.017).In future studies as well as clinical surveillance of BA patients' varices, successful and failed portoenterostomy patients should be approached as separate groups with divergent prognoses. After failed portoenterostomy, surveillance should start early, for example, at 6 months.

We related hepatic gene and serum expression of matrix metalloproteinases (MMP) and their tissue inhibitors (TIMP) to liver histology in pediatric LT recipients. Liver biopsies and serum samples were obtained from 52 patients 10.6 years post-LT and age-matched controls for analyses of MMPs and TIMPs. Patients with fibrosis had significantly higher hepatic gene expression of MMP-2, MMP-9, MMP-14, TIMP-1, and TIMP-2 than patients without. Expression of these genes correlated with graft Metavir fibrosis stage (r = 0.494-0.684, P ≤ 0.006 for all). Gene expression of MMP-1, MMP-3, MMP-8, TIMP-3, and TIMP-4 was undetectable in both patients and controls. Portal inflammation and cytokeratin 7 correlated positively with gene expression of TIMP-1. Gene expression of MMP-2, MMP-9, and TIMP-2 correlated negatively with the time of low-dose cortisone usage (r = -0.448 to -0.422, P < 0.05 for all). Serum concentrations of MMP-8 and TIMP-1 were significantly increased and MMP-9 decreased among patients compared with controls, but no correlations to graft histology or gene expression were observed. Hepatic gene expression of certain MMPs and TIMPs is increased in stable pediatric LT recipients displaying graft fibrosis, but this did not reflect to their serum concentrations. Increased hepatic gene expression of TIMP-1 correlated with graft fibrosis stage, inflammation, and chronic cholestasis.

To investigate the prevalence and predictors of psychological distress in adolescent and young adult (AYA) cancer patients and their parent caregivers.In a cross-sectional study design, AYA participants (n = 196) and parent caregivers (n = 204) were recruited from 18 sites across Australia. AYAs were aged 15-25 years at cancer onset and within 6-24 months of diagnosis. AYAs and parents completed a survey that includes validated measures of psychological distress (anxiety, depression, and posttraumatic stress symptoms [PTSS]). Additional measures included validated and study-specific questionnaires related to sociodemographic and medical information, social supports, cancer impacts, and life stressors.Nearly half the sample (48% AYAs and 42% parents) scored above a clinical cutoff score for PTSS, indicating further assessment was warranted. Nearly one third of AYAs and parents (31% AYAs and 28% parents) reported moderate to severely elevated symptoms of anxiety and depression. Factors associated with elevated AYA distress included female gender, less social support, and self-image and identity issues. For parents, living outside the metropolitan area, other life stressors, and impact on plans for the future and broader family were factors associated with increased distress.Despite numerous studies of AYA cancer survivors, very few studies have examined the psychosocial and psychological impacts of cancer when onset occurs during adolescence and young adulthood. Almost no studies have examined the impacts on their parent caregivers. The findings of this study support the need for early identification of psychological distress, appropriate developmental perspectives to understand AYA distress, and the need for family-based psychological assessment and interventions.

Liver transplantation (LT) predisposes to metabolic derangements and increases the risk for cardiovascular disease. We conducted a national cross-sectional study of all pediatric recipients who underwent LT between 1987 and 2007. We measured serum levels of noncholesterol sterols (surrogate markers of cholesterol synthesis and intestinal absorption) and fibroblast growth factor 21 (FGF21) in 49 patients (74% of survivors) at a median of 10 years posttransplant and in 93 controls matched for age and gender. Although serum cholesterol levels were similar in patients and controls, patients displayed increased whole-body synthesis and decreased intestinal absorption of cholesterol compared with controls (lathosterol to cholesterol ratio 129 ± 55 vs. 96 ± 41, respectively, p < 0.001; campesterol to cholesterol ratio 233 ± 91 vs. 316 ± 107, respectively; p < 0.001). Azathioprine (r =–0.383, p = 0.007) and low-dose methylpredisolone (r =–0.492, p < 0.001) were negatively associated with lathosterol/sitosterol ratio reflecting a favorable effect on cholesterol metabolism. FGF21 levels were higher in patients than in controls (248 pg/mL vs. 77 pg/mL, p < 0.001). In healthy controls, FGF21 was associated with cholesterol metabolism, an association missing in LT recipients. Normal serum lipids are achievable in long-term survivors of pediatric LT, but changes in cholesterol metabolism and increased FGF21 levels may explicate later cardiovascular risk.

In children, optimal timing of liver transplantation (LT) is crucial, but reliable prognostic tools for chronic liver diseases are scarce. We assessed the predictive value of galactose half-life (Gal½) for LT or death. A retrospective search of hospital database 2003-2010 revealed 92 consecutive children with chronic liver disease (36 biliary atresia) whose liver function was assessed with Gal½ measurement. Gal½, follow-up data, and liver biochemistry were recorded and pediatric/model for end-stage liver disease (P/MELD) scores calculated. Patients listed for LT or those who died within 1 year of the Gal½ measurement (Group 1) were compared to those surviving without listing (Group 2). Predictive value of Gal½ and P/MELD for listing for LT was assessed with area under the receiver operating characteristic curve (AUROC) analysis. Group 1 had markedly increased median Gal½ [17.0 (interquartile range 12.5-28.5) min] and higher P/MELD [13 (-1-23)] compared with group 2, [10.5 (9.5-12.5) min and -1 (-8-8); P < 0.001 for both]. Both Gal½ and P/MELD (P < 0.001) predicted listing or death with respective AUROCs of 0.808 (95% CI 0.704-0.913) and 0.780 (0.676-0.890), and 85% sensitivity and 69% specificity for Gal½≥12.0 min. Gal½ is a useful tool when evaluating 1-year prognosis in children with chronic liver disease.

Unresectable malignant liver tumors may be treated by LTx. We evaluated the results of LTx for HB and HCC. All patients transplanted for HB or HCC between 1990 and 2007 were included. Effects of histologic tumor type, primary tumor resection, disease staging, and serum AFP levels at diagnosis and at transplantation on disease recurrence and survival were evaluated. Twelve patients with median age of five (range, 2-16) were transplanted and followed for a median of 11 (2-18) yr. Six patients had HB and six had HCC. At diagnosis, eight patients were staged as PRETEXT III and four patients as PRETEXT IV. Two patients had pulmonary metastases. All patients received neoadjuvant chemotherapy. Median time from diagnosis to LTx was seven (2-133) months. At LTx, none of the patients had radiological evidence of extrahepatic disease, and the median AFP level was 85 (6-15 180) microg/L. No routine chemotherapy after LTx was used.The overall one-, five-, and 10-yr cumulative survival rates were 100%, 80%, and 67%, respectively. Survival was comparable between the two tumor types (4/6 for both). Two deaths occurred secondary to tumor recurrence, one of each tumor type. Both of these patients had an AFP response of

Background Despite improved survival rates of patients with pediatric intestinal failure (IF), data on health-related quality of life (HRQoL) of IF patients are still scarce. We hypothesized that I) continued parenteral nutrition, underlying intestinal motility disorder, abdominal pain and problematic bowel function would be associated with poorer HRQoL and higher parental stress levels, and II) the time intervals since the latest bowel operation, the latest episode of sepsis, and the latest inpatient care episode would be associated with better HRQoL and lower parental stress. Methods Patients with pediatric onset IF and their parents answered questionnaires on HRQoL, parental stress, and bowel-related symptoms. Clinical data were gathered by chart review. Controls matched for age and sex were randomly chosen by the Population Register Centre of Finland. Results Thirty-six (73%) IF patients participated at a median age of 9years. Overall HRQoL was similar to healthy peers, and frequent abdominal pain was the only factor associated with poorer HRQoL. Abdominal pain and stool frequency >3 times per day were associated with higher levels of parental stress, whereas longer time intervals since the latest bowel operation or hospitalization were associated with lower parental stress levels. Conclusion Long-term HRQoL of pediatric IF patients is comparable to that of healthy peers. Time often eases parental stress, but frequent abdominal pain presents a challenge to the well-being of some patients and requires medical attention.

Hepatic artery thrombosis (HAT) after liver transplantation (LT) increases patient morbidity and mortality. Early HAT is considered to occur within the first month after LT, whereas late HAT occurs after the first month. Few studies have addressed late HAT after LT, especially in pediatric patients. Between 1987 and 2007, 99 patients (age 18 years) underwent deceased donor LT. Thirty-four of 66 eligible patients (52%) underwent magnetic resonance imaging (MRI) according to protocol. On the basis of MRI findings, the patients were grouped as those who experienced late HAT and those who did not. Additionally, potential risk factors for late HAT were analyzed retrospectively. P values were adjusted for multiplicity. The median age at LT was 1.7 years [interquartile range (IQR) = 1.0-9.6 years], and the median follow-up time at MRI was 9.5 years (IQR = 4.0-16.4 years). Late HAT was diagnosed in 15 of the 34 patients [44%, 95% confidence interval (CI) = 29%-61%] undergoing MRI and in 3 of these patients with angiography preceding MRI. Ultrasonography revealed late HAT in 6 of these 15 patients with a sensitivity of 40% (95% CI = 20%-64%). The donor/recipient weight ratio remained significantly higher for the patients with late HAT versus the patients without late HAT after P values were adjusted (5.4 versus 1.9, P = 0.03). No marked differences were observed in laboratory or liver histology parameters between the groups. In conclusion, late HAT is common after pediatric LT. The donor/recipient weight ratio was higher for patients with late HAT, and this was attributable to the lower weight of the recipients. No salient features of late HAT were observed with respect to laboratory or histological parameters, at least in terms of our study's cross-sectional period.

Both Gal½ and P/MELD (P0.001) predicted listing or death with respective AUROCs of 0.808 (95% CI 0.704-0.913) and 0.780 (0.676-0.890), and 85% sensitivity and 69% specificity for Gal½≥12.0 min. Gal½ is a useful tool when evaluating 1-year prognosis in children with chronic liver disease.

Controversy remains about the role of protocol liver biopsy for symptom-free recipients and about the long-term use of low-dose steroids after pediatric liver transplantation (LT). We conducted a national cross-sectional study of pediatric recipients who underwent LT between 1987 and 2007. Liver biopsy samples were taken from 54 patients (82% of survivors) after a median posttransplant follow-up of 11 years, and they were reviewed by 2 pathologists blinded to the clinical data. Biopsy samples from 18 patients (33%) showed nearly normal histology with no inflammation, fibrosis, or steatosis. Portal inflammation was detected in 14 samples (26%), showed no correlation with anti-nuclear antibodies, and was less frequent in the 35 patients whose immunosuppression included steroids (14% versus 47% of patients not using steroids, P = 0.008). Fibrosis was present in 21 biopsy samples (39%). According to the Metavir classification, 16 were stage 1, 3 were stage 2, and 2 were stage 3. The fibrosis stage correlated negatively with serum prealbumin levels (r = -0.364, P = 0.007) and positively with chronic cholestasis (cytokeratin 7 staining; r = 0.529, P0.001) and portal inflammation (r = 0.350, P = 0.01). Microvesicular steatosis was found in 23 biopsy samples (43% of patients in 5%-80% of hepatocytes), and it correlated with the body mass index (r = 0.458, P0.001) but not with steroid use. The age of the allograft (donor age plus follow-up time) correlated with higher serum gamma-glutamyltransferase (r = 0.472, P0.001) and conjugated bilirubin levels (r = 0.420, P = 0.002) as well as chronic cholestasis (r = 0.299, P = 0.03). The biopsy findings led to treatment changes in 10 patients (19%), whereas only 1 complication (subcapsular hematoma) was encountered. In conclusion, continuing low-dose steroids indefinitely after pediatric LT may have a positive effect on the long-term histological state of the liver graft. Allograft aging may lead to chronic cholestasis and thus contribute to the development of liver fibrosis.

Effects of caseload and organization of care on outcomes of biliary atresia (BA) remain unclear. We compared outcomes before and after national centralization of BA treatment in Finland with a population of 5.4 million people and 60,000 live births/year.All children born in Finland from 1987 to 2010 with BA were included. Complete patient identification was ascertained from the national Register of Congenital Malformations. Hospital records were reviewed for confirmation of the diagnosis, treatment, and follow-up data. Clearance of jaundice (serum bilirubin ≤ 20 μmol/l) and survival modalities were compared before and after centralization from five centers to Helsinki.The incidence of BA was 1 in 20,100 live births. A total of 72 BA patients of whom 64 had undergone surgery for BA were identified. After centralization, the median caseload per center increased from 0 (range, 0-3) to 4 (2-5) patients/year (p0.001), clearance of jaundice rate increased from 27% to 75% (p = 0.001), 2-year jaundice-free native liver survival from 25% to 75% (p = 0.002), transplant-free survival from 27% to 75% (p = 0.005), and overall survival from 64% to 92% (p = 0.082). Baseline patient characteristics including type of BA and age at portoenterostomy remained unaltered. In a logistic regression analysis including treatment era, operating center, BA splenic malformation syndrome, and age at portoenterostomy as variables, only treatment in Helsinki after centralization predicted clearance of jaundice (odds ratio 4.2; 95% confidence interval 1.05-16.5; p = 0.043).In small countries, BA treatment should be centralized to appointed multidisciplinary teams allowing high quality results with a median of four cases/year.

The long-term impact of pediatric liver transplantation (LT) and its complications on general health, health-related quality of life (HRQoL) and sexual health were assessed. We conducted a national cross-sectional study of all pediatric recipients who underwent LT between 1987 and 2007. Of 66 survivors, 57 participants (86%) were compared to randomly chosen healthy controls (n = 141) at 10.7 ± 6.6 years posttransplant. PedsQL4.0, SF-36, DISF-SR and AUDIT questionnaires for appropriate age groups were used. Patients and controls

Vaginal laceration is rare following a water sport accident. Several cases have been reported in water-skiers and personal watercraft passengers. If a patient presents with vaginal bleeding after such an accident, careful examination under general anesthesia is recommended to detect deep trauma. We present a case of vaginal laceration from a water slide in a middle-aged healthy woman.

Unresectable malignant liver tumors may be treated by LTx. We evaluated the results of LTx for HB and HCC. All patients transplanted for HB or HCC between 1990 and 2007 were included. Effects of histologic tumor type, primary tumor resection, disease staging, and serum AFP levels at diagnosis and at transplantation on disease recurrence and survival were evaluated. Twelve patients with median age of five (range, 2-16) were transplanted and followed for a median of 11 (2-18) yr. Six patients had HB and six had HCC. At diagnosis, eight patients were staged as PRETEXT III and four patients as PRETEXT IV. Two patients had pulmonary metastases. All patients received neoadjuvant chemotherapy. Median time from diagnosis to LTx was seven (2-133) months. At LTx, none of the patients had radiological evidence of extrahepatic disease, and the median AFP level was 85 (6-15 180) microg/L. No routine chemotherapy after LTx was used.The overall one-, five-, and 10-yr cumulative survival rates were 100%, 80%, and 67%, respectively. Survival was comparable between the two tumor types (4/6 for both). Two deaths occurred secondary to tumor recurrence, one of each tumor type. Both of these patients had an AFP response of99%. Six of eight patients with primary LTx survived, when compared to two of four transplanted after primary resection. PRETEXT tumor staging had no effect on survival. LTx even without post-transplantation chemotherapy is an effective treatment option for unresectable HB and HCC with comparable survival. Incomplete AFP response to chemotherapy and primary tumor resection were associated with decreased survival.

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.

Biliary atresia is the most common indication for childhood liver transplantation. The effects of successful portoenterostomy (PE) on native liver histology remain unclear.We assessed changes in native liver histology after a successful PE in relation to liver function and clinical outcomes.In total, 70 native liver biopsies of 44 biliary atresia patients were obtained at PE (n=30), 4.2 years after successful PE (n=23) and 1.1 years after failed PE (n=17), and reviewed for cholestasis, fibrosis, inflammation, and cytokeratin 7 (CK7) immunopositivity (chronic cholestasis). Ten transplant donor livers served as controls.After a successful PE [serum bilirubin 11 (2 to 35) μmol/L at biopsy], histologic native liver cholestasis completely resolved in 83% of the patients and portal inflammation significantly decreased. Nevertheless, enhanced fibrosis [Metavir stage 2 (1-4) vs. 4 (1-4)], bile duct proliferation [grade 2 (1-2) vs. 1 (0-2)], and periportal CK7 immunostaining [grade 1 (0-2) vs. 1 (0-4)] persisted in 100%, 87%, and 61% of subjects, respectively. Metavir fibrosis stage corresponded cirrhosis (stage 4) in 52% of the patients, associated with the presence of portal hypertension, and correlated with serum-conjugated bilirubin (r=0.601, P=0.002), bile duct proliferation (r=0.657, P=0.001), and CK7 positivity (r=0.657, P=0.001). Aspartate transferase to platelet ratio index predicted native liver fibrosis and development of esophageal varices. The degree of fibrosis and portal inflammation at PE were unrelated to native liver survival.Despite resolution of cholestasis and decreasing inflammation, bile duct proliferation, periportal CK7 immunostaining, and fibrosis persist after successful PE. Fibrosis is associated with biochemical cholestasis, bile duct proliferation, CK7 immunopositivity (chronic cholestasis), and development of portal hypertension.
