Hospitalization- and death-related financial and employment effects in parents of children with life-limiting conditions: a fixed-effects analysis.

The purpose of this study is to investigate out-of-pocket non-medical expenses and employment-related outcomes in families of children with life-limiting conditions, specifically, to quantify the financial and employment implications of two events: a child's hospitalization and death. This cohort study used panel data collected prospectively for a larger study investigating the effectiveness of specialized pediatric palliative care. Participants were recruited by medical professionals between November 2019 and May 2022 at four Swiss children's hospitals. The care follow-up and bereavement follow-up assessments were 330 and 300 days, respectively. We measured out-of-pocket non-medical expenses, individual full-time equivalent units, and personal income, as well as sick leave and vacation days taken. Analyses included descriptive statistics and two-way linear fixed-effects regressions. The analysis included 110 parents (mothers n = 59, fathers n = 51) of 61 children. Children were hospitalized for a median of 7 days (interquartile range 0-21, range 0-227). The fixed-effects models found a positive association between hospitalization, i.e., length of stay, and travel and accommodation expenses (coefficient 4.18, 95% confidence interval 2.20-6.16). On average, for each week of hospitalization, parents spent an additional 29 Swiss francs on travel and accommodation. During the 300-day bereavement follow-up, six (26%) of 23 parents increased their work commitments, while one reported a decrease. CONCLUSIONS: Families incur higher travel and accommodation expenses during hospitalization than during non-hospitalized periods. Instrumental support, e.g., parking vouchers, can help families minimize these costs. Future studies should investigate whether early return to work during bereavement is driven by economic considerations or a desire for distraction. CLINICAL TRIAL REGISTRATION: Data analyzed in this study were collected as part of a clinical trial, registered on ClinicalTrials.gov, No. NCT04236180, 15 March 2019 What Is Known: • Families of children with life-limiting conditions are at risk of substantial financial burden from high out-of-pocket medical expenses. • It is also known that parents often have to incur out-of-pocket non-medical expenses and reduce their work commitments. Little is known about the economic consequences of losing a child to a life-limiting condition. WHAT IS NEW: • We provide new longitudinal evidence on the hospitalization- and death-related financial and employment implications for families of children with life-limiting conditions. • Child hospitalizations add to families' financial burden through increased travel and accommodation expenses. Work commitments rose during early bereavement.

Advanced Imaging and New Cardiac Biomarkers in Long-term Follow-up After Childhood Cancer.

OBJECTIVES: Pathologic ejection fraction (EF), shortening fraction (FS), and standard heart failure biomarkers (high sensitive troponin T and N-terminal brain natriuretic peptide) during follow-up after childhood cancer have been associated with irreversible cardiac damage. We aimed to evaluate strain imaging values by echocardiography and new biomarkers for heart failure with preserved ejection fraction (HFpEF) as potential more sensitive parameters for cardiac deterioration in childhood cancer survivors (CCS). MATERIALS AND METHODS: Prospective study with 50 CCS (median 16.2 y) at a median follow-up of 13 years. In addition to standard echo and laboratory parameters for heart failure, strain measurements and new biomarkers, including myocardial inflammation (interleukin 6), extracellular matrix (ECM) remodeling (C-telopeptide for type I collagen, intact N-terminal propeptide of type III procollagen), and other heart failure biomarkers (galectin 3, solutable ST2, growth differentiation factor 15), were obtained and compared with 50 healthy controls. RESULTS: No significant differences in EF, FS, high sensitive troponin T, N-terminal brain natriuretic peptide, interleukin 6, solutable ST2, and galectin 3 were found between study and control groups. In contrast, strain imaging showed significant differences between both groups (global longitudinal strainGLS -16.1% vs. -20.4%, P<0.0001; global circumferential strain -14.3 vs. -21.4%, P<0.0001), detecting 66% (global longitudinal strain) and 76% (global circumferential strain) of patients with pathologic values in contrast to 6% (EF) and 16% (FS) for standard parameters. Markers for disturbances of ECM remodeling (C-telopeptide for type I collagen, intact N-terminal propeptide of type III procollagen, each P<0.0001) and growth differentiation factor 15 (P<0.0001) were significantly different between the groups. CONCLUSION: Strain imaging and new cardiac biomarkers used in HFpEF focusing on ECM remodeling appear to be more sensitive in detecting early remodeling processes in CCS than standard echo and laboratory parameters.

Measuring Financial Burden in Families of Children Living With Life-Limiting Conditions: A Scoping Review of Cost Indicators and Outcome Measures.

OBJECTIVES: This study aimed to provide a comprehensive overview of cost indicators and outcome measures used to measure financial burden in families of children with life-limiting conditions. METHODS: A scoping review methodology was used to map the existing literature and provide an overview of available cost indicators and outcome measures. Key medical, economic, and scientific databases were systematically searched to identify relevant articles published in 2000 or later. RESULTS: The database search yielded 7194 records, including 30 articles eligible for final inclusion. Retrieved cost indicators and outcome measures fell into 3 broad categories: direct costs, indirect costs, and financial support. No study comprehensively assessed all 3 categories. Cost indicators used to measure direct costs were grouped into 5 medical and 11 nonmedical out-of-pocket expenses categories, of which 5 were commonly assessed (ie, treatment and diagnostics, travel and transport, accommodation, food, childcare and home help). Half of the reviewed studies included assessments of indirect costs, most commonly estimating work-related income loss by evaluating employment disruptions. Assessments of opportunity costs arising from informal caregiving and of financial support were rarely included. CONCLUSIONS: Current estimates of the financial burden faced by families of children with life-limiting conditions are inconsistent and often incomplete, likely resulting in severe underestimations of the costs these families incur. We hope that the framework presented in this article will contribute to a more comprehensive assessment of illness-related financial burden and help guide future policies in this area.

Combining the best interest standard with shared decision-making in paediatrics-introducing the shared optimum approach based on a qualitative study.

Paediatric decision-making is the art of respecting the interests of child and family with due regard for evidence, values and beliefs, reconciled using two important but potentially conflicting concepts: best interest standard (BIS) and shared decision-making (SD-M). We combine qualitative research, our own data and the normative framework of the United Nations Convention on the Rights of Children (UNCRC) to revisit current theoretical debate on the interrelationship of BIS and SD-M. Three cohorts of child, parent and health care professional interviewees (Ntotal = 47) from Switzerland and the United States considered SD-M an essential part of the BIS. Their responses combined with the UNCRC text to generate a coherent framework which we term the shared optimum approach (SOA) combining BIS and SD-M. The SOA separates different tasks (limiting harm, showing respect, defining choices and implementing plans) into distinct dimensions and steps, based on the principles of participation, provision and protection. The results of our empirical study call into question reductive approaches to the BIS, as well as other stand-alone decision-making concepts such as the harm principle or zone of parental discretion.Conclusion: Our empirical study shows that the BIS includes a well-founded harm threshold combined with contextual information based on SD-M. We propose reconciling BIS and SD-M within the SOA as we believe this will improve paediatric decision-making. What is Known: • Parents have wide discretion in deciding for their child in everyday life, while far-reaching treatment decisions should align with the child's best interest. • Shared decision-making harbours potential conflict between parental authority and a child's best interest. What is New: • The best interest standard should not be used narrowly as a way of saying "Yes" or "No" to a specific action, but rather in a coherent framework and process which we term the shared optimum approach. • By supporting this child-centred and family-oriented process, shared decision-making becomes crucial in implementing the best interest standard.

THROMBOTECT - a randomized study comparing low molecular weight heparin, antithrombin and unfractionated heparin for thromboprophylaxis during induction therapy of acute lymphoblastic leukemia in children and adolescents.

Thromboembolism is a serious complication of induction therapy for childhood acute lymphoblastic leukemia. We prospectively compared the efficacy and safety of antithrombotic interventions in the consecutive leukemia trials ALL-BFM 2000 and AIEOP-BFM ALL 2009. Patients with newly diagnosed acute lymphoblastic leukemia (n=949, age 1 to 18 years) were randomized to receive low-dose unfractionated heparin, prophylactic low molecular weight heparin (enoxaparin) or activity-adapted antithrombin throughout induction therapy. The primary objective of the study was to determine whether enoxaparin or antithrombin reduces the incidence of thromboembolism as compared to unfractionated heparin. The principal safety outcome was hemorrhage; leukemia outcome was a secondary endpoint. Thromboembolism occurred in 42 patients (4.4%). Patients assigned to unfractionated heparin had a higher risk of thromboembolism (8.0%) compared with those randomized to enoxaparin (3.5%; P=0.011) or antithrombin (1.9%; P<0.001). The proportion of patients who refused antithrombotic treatment as allocated was 3% in the unfractionated heparin or antithrombin arms, and 33% in the enoxaparin arm. Major hemorrhage occurred in eight patients (no differences between the groups). The 5-year event-free survival was 80.9±2.2% among patients assigned to antithrombin compared to 85.9±2.0% in the unfractionated heparin group (P=0.06), and 86.2±2.0% in the enoxaparin group (P=0.10). In conclusion, prophylactic use of antithrombin or enoxaparin significantly reduced thromboembolism. Despite the considerable number of patients rejecting the assigned treatment with subcutaneous injections, the result remains unambiguous. Thromboprophylaxis - for the present time primarily with enoxaparin - can be recommended for children and adolescents with acute lymphoblastic leukemia during induction therapy. Whether and how antithrombin may affect leukemia outcome remains to be determined.

[Paediatric Palliative Care: What is different in children compared to adults?] / Pädiatrische Palliative Care: was ist bei Kindern anders als bei Erwachsenen?

Paediatric Palliative Care: What is different in children compared to adults? Abstract. The number of children and adolescents (0 - 18 years) with life-limiting conditions and needs for paediatric palliative care (PPC) is rising. In Switzerland, the awareness for these needs lags largely behind other developed countries. In the United Kingdom, the prevalence for children with life-limiting conditions and PPC needs was estimated at 32 children per 10'000 population (0 - 19 years). In Switzerland, this would correspond to an absolute number of 5'000 children living with a life-limiting condition and potentially in need of PPC. In contrast, the number of deaths accounts for around 500 children (0 - 18 years) every year. Most common causes of death are perinatal conditions, contributing to nearly 50 % of all deaths in childhood, followed by accidents and complex chronic conditions such as genetic / congenital disorders, neurological and cardiac conditions and cancer. Compared to adults with palliative care needs, the group of children is significantly smaller but at the same time highly heterogenic. Heterogeneity relates to: the whole age continuum from neonates, infants and children to adolescents; a broad spectrum of diseases including rare diseases; a variety of needs due to age, development and the illness, e. g. needs for specialist care or technical support; various in- and outpatient settings. Paediatric care always encompasses the whole family and their particular needs. Internationally, hospital-based programmes have been developed and implemented to meet these particular needs of children and their families.

Information needs in parents of long-term childhood cancer survivors.

BACKGROUND: Parents' knowledge about cancer, treatment, potential late effects and necessary follow-up is important to reassure themselves and motivate their child to participate in regular follow-up. We aimed to describe (i) parents' perception of information received during and after treatment; (ii) parents' current needs for information today, and to investigate; and (iii) associations between information needs and socio-demographic and clinical characteristics. METHODS: As part of the Swiss Childhood Cancer Survivor Study, a follow-up questionnaire was sent to parents of survivors, diagnosed < 16 years and after 1990, and aged 11-17 years at study. We assessed parents' perception of information received and information needs, concerns about consequences of the cancer and socio-demographic information. Information on clinical data was available from the Swiss Childhood Cancer Registry. RESULTS: Of 309 eligible parents, 189 responded (67%; mean time since diagnosis: 11.3 years, SD = 2.5). Parents perceived to have received verbal information (on illness: verbal 91%, written 40%; treatment: verbal 88%, written 46%; follow-up: verbal 85% written 27%; late effects: verbal 75%, written 19%). Many parents reported current information needs, especially on late effects (71%). The preferred source was written general (28%) or verbal information (25%), less favored was online information (12%). Information needs were associated with migration background (P = 0.039), greater concerns about consequences of cancer (P = 0.024) and no information received (P = 0.035). CONCLUSION: Parents reported that they received mainly verbal information. However, they still needed further information especially about possible late effects. Individual long-term follow-up plans, including a treatment summary, should be provided to each survivor, preferably in written format.

qPET - a quantitative extension of the Deauville scale to assess response in interim FDG-PET scans in lymphoma.

BACKGROUND: Interim FDG-PET is used for treatment tailoring in lymphoma. Deauville response criteria consist of five ordinal categories based on visual comparison of residual tumor uptake to physiological reference uptakes. However, PET-response is a continuum and visual assessments can be distorted by optical illusions. OBJECTIVES: With a novel semi-automatic quantification tool we eliminate optical illusions and extend the Deauville score to a continuous scale. PATIENTS AND METHODS: SUVpeak of residual tumors and average uptake of the liver is measured with standardized volumes of interest. The qPET value is the quotient of these measurements. Deauville scores and qPET-values were determined in 898 pediatric Hodgkin's lymphoma patients after two OEPA chemotherapy cycles. RESULTS: Deauville categories translate to thresholds on the qPET scale: Categories 3, 4, 5 correspond to qPET values of 0.95, 1.3 and 2.0, respectively. The distribution of qPET values is unimodal with a peak representing metabolically normal responses and a tail of clearly abnormal outliers. In our patients, the peak is at qPET = 0.95 coinciding with the border between Deauville 2 and 3. qPET cut values of 1.3 or 2 (determined by fitting mixture models) select abnormal metabolic responses with high sensitivity, respectively, specificity. CONCLUSIONS: qPET methodology provides semi-automatic quantification for interim FDG-PET response in lymphoma extending ordinal Deauville scoring to a continuous scale. Deauville categories correspond to certain qPET cut values. Thresholds between normal and abnormal response can be derived from the qPET-distribution without need for follow-up data. In our patients, qPET < 1.3 excludes abnormal response with high sensitivity.

Work-related quality of life in professionals involved in pediatric palliative care: a repeated cross-sectional comparative effectiveness study.

Background: Working in pediatric palliative care (PPC) impacts healthcare and allied professionals' work-related quality of life (QoL). Professionals who lack specific PPC training but who regularly provide services to the affected children have articulated their need for support from specialized PPC (SPPC) teams. Objectives: This study had two objectives: (1) to evaluate whether the availability of a SPPC team impacted the work-related QoL of professionals not specialized in PPC; and (2) to explore the work-related QoL of professionals working in PPC without specialized training. Design: Repeated cross-sectional comparative effectiveness design. Methods: One hospital with an established SPPC program and affiliated institutions provided the intervention group (IG). Three hospitals and affiliated institutions where generalist PPC was offered provided the comparison group (CG). Data were collected by paper-pencil questionnaire in 2021 and 2022. The Professional Quality of Life (ProQOL 5) questionnaire was used to assess work-related QoL, yielding separate scores for burnout (BO), secondary traumatic stress (STS) and compassion satisfaction (CS). A descriptive statistical analysis was performed and general estimation equations were modelled. To increase the comparability of the IG and CG, participants were matched by propensity scores. Results: The 301 participating non-PPC-specialized professionals had overall low to moderate levels of BO and STS and moderate to high levels of CS. However, none of these scores (BO: p = 0.36; STS: p = 0.20; CS: p = 0.65) correlated significantly with support from an SPPC team. Compared to nurses, physicians showed higher levels of BO (1.70; p = 0.02) and STS (2.69; p ⩽ 0.001). Conclusion: Although the study sample's overall work-related QoL was satisfactory, it showed a considerable proportion of moderate BO and STS, as well as moderate CS. To provide tailored support to professionals working in PPC, evidence regarding key SPPC support elements and their effectiveness is needed. Trial registration: ClinicalTrials.gov ID, NCT04236180.

Work-related quality of life in professionals involved in pediatric palliative care - Why was this study done? Caring for children suffering from life-limiting conditions and their families impacts professionals' work-related Quality of Life (QoL). Professionals without specific training often provide pediatric palliative care (PPC) to children and their families. - What did the researchers do? We aimed to determine whether the work-related the QoL of professionals without specialised PPC training would be positively influenced when they were supported by PPC specialists. We also wanted to explore what person-specific factors might correspond with higher or lower work-related QoL. Work-related QoL was analysed in relation to burnout (BO), secondary traumatic stress (STS), and compassion satisfaction (CS). These variables' levels were assessed with a questionnaire survey in 2021 and 2022. - What did the researchers find? The 301 participating professionals had overall low to moderate levels of BO and STS and moderate to high levels of CS. There was no substantial difference in work-related QoL in the professionals supported by PPC specialists compared to those who did not receive specialist support. Physicians showed higher levels of BO and STS than nurses. - What do the findings mean? Although the studied professionals' overall work-related QoL was satisfactory, there is a considerable proportion of moderate BO and STS scores in professionals working with children suffering from life-limiting conditions. Further research should explore the specific needs of professionals not specialised in PPC.

Port-a-cath-related thrombosis and postthrombotic syndrome in pediatric oncology patients.

OBJECTIVE: To investigate Port-A-Cath (PAC)-related thrombosis and postthrombotic syndrome (PTS) in children with cancer. STUDY DESIGN: The study population was a consecutive cohort of children diagnosed with cancer and a PAC implanted at diagnosis. Children were evaluated for the presence of PAC-related thrombosis by magnetic resonance venography and the presence of congenital prothrombotic risk factors and PTS. RESULTS: A total of 114 children (median age, 6.04 years) were included. Of these children, 48 (42%) were treated for solid tumors and 66 (58%) were treated for hematopoietic tumors, including 38 for acute lymphoblastic leukemia. At the time of magnetic resonance venography, 42 children (37%) had the PAC still in place, and 72 (63%) had the PAC removed. Overall, PACs were in place for a total of 324.92 PAC-years. PAC-related thrombosis was detected in 45 children (39.5%) with a current or previous PAC. Of these, 21 (47%) had a solid tumor, 14 (31%) had acute lymphoblastic leukemia, and 10 (22%) had another hematopoietic tumor. Younger age at diagnosis, female sex, duration of PAC use, and left-side PAC placement were independently associated with an increased risk of thrombosis, whereas asparaginase therapy and the presence of inherited prothrombotic risk factors were not. Mild PTS (ie, presence of prominent collateral vessels in the skin) was present in 5.6% of the children. CONCLUSION: PAC-related thrombosis is common in pediatric oncology patients. In some children, thrombotic complications can lead to the development of PTS.

The funding of specialised paediatric palliative care in Switzerland: a conceptualisation and modified Delphi study on obstacles and priorities.

BACKGROUND: Effective funding models are key for implementing and sustaining critical care delivery programmes such as specialised paediatric palliative care (SPPC). In Switzerland, funding concerns have frequently been raised as primary barriers to providing SPPC in dedicated settings. However, systematic evidence on existing models of funding as well as primary challenges faced by stakeholders remains scarce. AIMS: The present study's first aim was to investigate and conceptualise the funding of hospital-based consultative SPPC programmes in Switzerland. Its second aim was to identify obstacles to and priorities for funding these programmes sustainably. METHODS:  A 4-step process, including a document analysis, was used to conceptualise the funding of hospital-based consultative SPPC programmes in Switzerland. In consultation with a purposefully selected panel of experts in the subject, a 3-round modified Delphi study was conducted to identify funding-relevant obstacles and priorities regarding SPPC. RESULTS: Current funding of hospital-based consultative specialised paediatric palliative care programmes is complex and fragmented, combining funding from public, private and charitable sources. Overall, 21 experts participated in the first round of the modified Delphi study, 19 in round two and 15 in round three. They identified 23 obstacles and 29 priorities. Consensus (>70%) was obtained for 12 obstacles and 22 priorities. The highest level of consensus (>90%) was achieved for three priorities: the development of financing solutions to ensure long-term funding of SPPC programmes; the provision of funding and support for integrated palliative care; and sufficient reimbursement of inpatient service costs in the context of high-deficit palliative care patients. CONCLUSION: Decision- and policy-makers hoping to further develop and expand SPPC in Switzerland should be aware that current funding models are highly complex and that SPPC funding is impeded by many obstacles. Considering the steadily rising prevalence of children with life-limiting conditions and the proven benefits of SPPC, improvements in funding models are urgently needed to ensure that the needs of this highly vulnerable population are adequately met.

Palliative Care in Children With Advanced Heart Disease in a Tertiary Care Environment: A Mini Review.

Palliative care for children continues to evolve. More recently, this has also been true in the field of pediatric cardiology, particularly for children with advanced heart disease. In these children, similarly to children with cancer, treatment successes are offset by the risks of long-term morbidities, including premature death. This mini review aims to provide an overview of current knowledge on children suffering from advanced heart disease, their medical care during various phases of illness (including the palliative and end-of-life phase), symptom burden, experiences of parents, prognostic understanding of parents and physicians, and current status of the involvement of pediatric palliative care. In conclusion, the suffering of these children at the end of their young lives is pronounced and many parents feel prepared neither for medical problems nor for the child's death. An effective and mutually trusting partnership between pediatric cardiology and pediatric palliative care would appear to be a prerequisite for the timely involvement of palliative care in further supporting these children and their families.

"This is the worst that has happened to me in 86 years": A qualitative study of the experiences of grandparents losing a grandchild due to a neurological or oncological disease.

PURPOSE: Pediatric palliative care focuses mainly on the children suffering from a life-limiting disease, but always includes parents and siblings. However, grandparents are also often highly involved in caring for the child and require additional attention. Therefore, the aim of this study was to investigate the experiences of grandparents during the end-of-life care and after the death of a grandchild. DESIGN AND METHODS: A qualitative approach using semi-structured interviews was chosen. Fifteen grandparents of 10 children who had died of neurological or oncological diseases were interviewed. Participants were recruited among the families cared by the pediatric palliative care team of a children's hospital in northern Switzerland. Grandparents were interviewed at least 1 year after the death of the grandchild. The data was analyzed employing reconstructive interview analysis. RESULTS: Regardless of the child's diagnosis and circumstances of death, the participants described how the child's death had a major impact on them and their entire family. Grandparents felt obligated to support the family and constantly be a source of support for the parents. They bore a heavy psychological burden as they cared and mourned not only for their dying grandchild but also for their own daughter or son. Grandparents struggled with their ability to communicate about disease and death. They tried to process and make sense of their loss by remembering the deceased child. PRACTICE IMPLICATIONS: These findings emphasize the importance of identifying and understanding grandparents' suffering. Pediatric palliative care teams can achieve this by actively making contact with grandparents, taking their concerns seriously and demonstrating appreciation for their role in supporting the family.

Self-monitoring of oral anticoagulation therapy in children.

This study aimed to investigate the accuracy of home International Normalized Ratio (INR) self-monitoring in pediatric patients on long-term oral anticoagulation therapy. Statistical and clinical agreement of INR values from capillary whole blood samples measured by 2 different portable prothrombin time monitors (CoaguChek S and XS) and venous blood samples measured by a laboratory coagulation analyzer were evaluated using the Bland-Altman analysis. Eighty-three INR comparisons (56 using the CoaguChek S and 27 using the CoaguChek XS) were obtained from 35 children aged 4 months to 18 years. Mean differences between venous and capillary INR values and their limits of agreement were -0.04 (-0.63 to 0.55) overall, 0.006 (-0.63 to 0.65) for the CoaguChek S and -0.13 (-0.57 to 0.31) for the CoaguChek XS. The Pearson correlation coefficients were 0.88 overall, 0.84 for the CoaguChek S and 0.95 for the CoaguChek XS. Expanded and narrow agreements for all patients were 97.6 and 94%, respectively. In conclusion, home INR self-monitoring is accurate for children requiring long-term oral anticoagulation therapy. Our data suggest that INR self-monitoring with the newer CoaguChek XS is more accurate than with the older CoaguChek S monitor.

Karyotypic characterization of infant embryonal rhabdomyosarcoma.

Despite embryonal rhabdomyosarcoma (eRMS) representing the most frequent form of RMS, the karyotypic characterization of this tumor subtype is still incomplete. We report the karyotypic analysis of two new cases of infant-onset eRMS. Both cases had a hyperdiploid karyotype, including gain of chromosomes 2 and 8. Only one of the cases showed a structural aberration, an unbalanced rearrangement involving 4p. These cases, together with a review of the literature, suggest that a karyotypic subgroup exists in infant eRMS that is defined by hyperdiploidy (<53 chromosomes) and includes gain of chromosomes 2, 8, 11, and 17, with few or no structural aberrations. Hence, this report illustrates that distinct karyotypic subgroups may be found in eRMS, which ultimately may be shown to have prognostic relevance.

Normal values for aortic diameters in children and adolescents--assessment in vivo by contrast-enhanced CMR-angiography.

BACKGROUND: Contrast-enhanced CMR angiography (CE-CMRA) is being increasingly used for diagnosing aortic arch anomalies, planning interventions and follow-up assessment. We sought to establish normal values for the diameters of the thoracic aorta and reference curves related to body growth in children using CE-CMRA. RESULTS: CE-CMRA was performed in 53 children without cardiovascular disease. The median age was 9 years (range 2 - 20 years), weight 30 kg (range 12 - 75 kg), height 131 cm (range 81 - 184 cm), body surface area (BSA) 1.05 m2 (range 0.52-1.9 m2). Aortic diameters were measured at nine standardized sites on oblique maximum-intensity projection (MIP) images. Regression analysis of diameters in relation to BSA demonstrated linear relationship between the cross-sectional aortic diameters and the square root of BSA (BSA0.5). Normative diameters were (0.57 + 19.37*BSA0.5) mm for the aortic sinus, (-3.52 + 18.66*BSA0.5) mm for the first segment of the aortic arch, (-3.37 + 16.52*BSA0.5) mm for the isthmic region and (-1.27 + 9.89*BSA0.5) mm for the descending aorta at the level of the diaphragm. Normative curves are presented. CONCLUSION: This study provides normative values for aortic diameters in children measured by CE-CMRA. These data may serve for making the diagnosis of pediatric arch anomalies, assessing the need for treatment and planning interventions.

Immunosuppressive therapy with anti-thymocyte globulin and cyclosporine A in selected children with hypoplastic refractory cytopenia.

It is currently unknown whether immunosuppressive therapy or hematopoietic stem cell transplantation is the most appropriate treatment strategy for children with refractory cytopenia and normal karyotype or trisomy 8. We report on 31 children with hypoplastic refractory cytopenia treated with immunosuppressive therapy consisting of antithymocyte globulin and cyclosporine. At 6 months, 22 of 29 evaluable patients had a complete or partial response; a total of ten patients achieved a complete response at varying time points. Six patients subsequently received a transplant because of non-response, progression to advanced myelodysplastic syndrome or evolution of monosomy 7. Overall and failure-free survival rates at 3 years were 88% and 57%, respectively.
