Adult life after surviving lymphoma in childhood

Introduction: Almost all pediatric lymphomas are malignant, high-grade tumors. The combined incidence of Hodgkin's disease (HD) and non-Hodgkin lymphoma (NHL) reaches 10 to 12 new cases a year per million children under the age of 16years, representing about 10% of all pediatric cancers. HD makes up to 40% and NHL 60% of pediatric lymphomas. During the last 20years, cure rates raised dramatically so that currently over 90% of children and adolescents with HD and about 80% of those with NHL can be cured. As cure can be achieved in a large majority of patients, long-term effects and quality of life of the survivors are nowadays the principal challenges to pediatric oncologists. Discussion: Like survivors from acute lymphoblastic leukemia, young adults cured from NHL may present with neurocognitive deficits, especially if treated at a young age and with cranial irradiation. Intrathecal or high-dose intravenous chemotherapy with methotrexate may induce the same problems, although in a lesser extent and severity. Large enough prospective cohort studies like the CCSS in the USA were able to show an increased risk of second malignant neoplasms, especially brain tumors in patients formerly treated with cranial irradiation. Reduced fertility can follow exposure to cyclophosphamide, especially in the male. Cardiac function must be serially evaluated over the long to very long-term because of potential cardiomyopathy after high anthracycline doses and/or mediastinal irradiation. Survivors from HD are at high risk of late complications. Radiation therapy to the neck and mediastinum (mantle field) induces a 50% risk of developing hypothyroidism and a 20% risk of developing thyroid nodules at 20years. The risk of thyroid cancer is 18 times higher the expected rate for the general population. Secondary aggressive breast cancer shows a cumulative risk of 30% at 30years after radiotherapy. Other structures affected by mediastinal irradiation are the heart (pericardial, myocardial and endocardial structures), the great arteries (fibrosis, stenosis, aneurysms) and the central portion of the lungs (diffusion troubles, restrictive pneumopathy). Cardiac toxicity can be enhanced by the concomitant therapy with adriamycin and lung toxicity by bleomycin. Radiotherapy to the paraaortic and iliacal lymph nodes can affect gonadal function both in males and females; concomitant chemotherapy with alkylating agents like cyclophosphamide and especially procarbazine have a synergistic action and can lead to premature menopause as well as infertility. Although the vast majority of survivors from pediatric lymphomas fare well, a minority present with extreme symptoms of depression and psychosomatic distress; female sex, low socio-economic status and treatment with intensive chemotherapy are important risk factors for a poor psychosocial outcome. Conclusion: It is therefore crucial, but not always easy, to inform patients and families about potential late effects and organize follow-up after the pediatric age. A well functioning network of pediatric oncologists, GP's, adult oncologists and other specialists of adult medicine must be developed in order to prevent, early detect and treat expected long-term toxicitie

Microangiopathic Anemia without Thrombocytopenia and Kidney Disease in a Child with Diarrhea Caused by Shiga Toxin-Producing Escherichia coli

A child with a history of diarrhea presented with transient anemia, reticolucytosis, and red blood cell fragmentation. Blood pressure and levels of blood platelets, creatinine, and urea were normal, as were results of urinalysis. Escherichia coli harboring genes for Shiga toxin were detected in stool specimens. It is concluded that extraintestinal diseases caused by Shiga toxin-producing bacteria sometimes present without any renal involvemen

Birefringence measurements in fibers without polarizer

A method for measuring the delay between polarization eigenmodes in either high- or low-birefringence fibers is described. The main advantage of this interferometric method is its ability to perform the measurements without the use of any polarizing device. This results in particularly easy handling and makes this technique very suitable for systematic fiber controls. The obtained accuracy using an all-fiber setup is 0.02 ps/m for highly birefringent fibers and 0.003 ps/m when the birefringence is low

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

Mental health-care utilization in survivors of childhood cancer and siblings: the Swiss childhood cancer survivor study

Purpose: We aimed to (1) describe the utilization of mental health-care in survivors and siblings, the association with severity of distress, and visits to other professionals in distressed survivors not utilizing mental health-care; and (2) identify factors associated with utilization of mental health-care in distressed survivors. Methods: Within the Swiss Childhood Cancer Survivor Study, we sent postal questionnaires to all participants aged <16years at diagnosis (1976-2003), who survived ≥5years after diagnosis and were aged ≥16years at study. Survivors and siblings could indicate if they utilized mental health-care in the past year. Psychological distress was assessed with the Brief Symptom Inventory-18 (BSI-18). Participants with scores T ≥ 57 on two of three scales or the Global Severity Index were considered distressed. Results: We included 1,602 survivors and 703 siblings. Overall, 160 (10%) and 53 (8%), utilized mental health-care and 203 (14%) and 127 (14%) were considered distressed. Among these, 69 (34%) survivors and 20 (24%) siblings had utilized mental health-care. Participants with higher distress were more likely to utilize mental health-care. Distressed survivors not utilizing mental health-care were more likely to see a medical specialist than nondistressed. In the multivariable regression, factors associated with utilizing mental health-care were higher psychological distress and reporting late effects. Conclusions: Our results underline the importance of developing interventional programs and implementing psychological screening in follow-up of survivors. It is also important to systematically address siblings' needs. In follow-up, patients at risk should be informed about existing possibilities or advised to visit mental health professionals

Social, emotional, and behavioral functioning in young childhood cancer survivors with chronic health conditions.

BACKGROUND The cancer diagnosis and its intensive treatment may affect the long-term psycho-social adjustment of childhood cancer survivors. We aimed to describe social, emotional, and behavioral functioning and their determinants in young childhood cancer survivors. PROCEDURE The nationwide Swiss Childhood Cancer Survivor Study sends questionnaires to parents of survivors aged 5-15 years, who have survived at least 5 years after diagnosis. We assessed social, emotional, and behavioral functioning using the Strengths and Difficulties Questionnaire (SDQ). The SDQ includes four difficulties scales (emotional, conduct, hyperactivity, peer problems), a total difficulties indicator, and one strength scale (prosocial). We compared the proportion of survivors with borderline and abnormal scores to reference values and used multivariable logistic regression to identify determinants. RESULTS Our study included 756 families (response rate of 72%). Thirteen percent of survivors had abnormal scores for the total difficulties indicator compared to 10% in the general population. The proportion of survivors with abnormal scores was highest for the emotional scale (15% vs. 8% in the general population), followed by the peer problems scale (14% vs. 7%), hyperactivity (8% vs. 10%), and conduct scale (6% vs. 7%). Few survivors (4% vs. 7%) had abnormal scores on the prosocial scale. Children with chronic health conditions had a higher risk of borderline and abnormal scores on all difficulties scales (all p < 0.05). CONCLUSION Most childhood cancer survivors do well in social, emotional, and behavioral life domains, but children with chronic health conditions experience difficulties. Therefore, healthcare professionals should offer specific psycho-social support to these survivors

Chronic health conditions after childhood Langerhans cell histiocytosis: Results from the Swiss Childhood Cancer Survivor Study.

PURPOSE Langerhans cell histiocytosis (LCH) is a rare disease characterized by dysregulated proliferation of myeloid marrow progenitors and subsequent organ infiltration. While LCH is associated with a favorable prognosis, some survivors may develop chronic health conditions (CHC) because of the disease. In this study, we aimed to assess the spectrum and prevalence of CHC among LCH survivors compared with siblings and identify factors associated with the development of CHC. METHODS The Swiss Childhood Cancer Survivor Study sent questionnaires to all ≥ 5-year LCH survivors registered in the Swiss Childhood Cancer Registry and diagnosed between 1976 and 2015. Siblings also received similar questionnaires. We compared CHC prevalence between LCH survivors and siblings and used logistic regression to identify determinants of CHC. RESULTS A total of 123 LCH survivors participated in the study, with a response rate of 69%. Median time since diagnosis was 13 years (interquartile range 9-20). Among LCH survivors, 59% had at least one CHC. Cardiovascular (13% vs. 6%), endocrine (15% vs. 2%), musculoskeletal (22% vs. 13%), and digestive (15% vs. 8%) CHC were more common among LCH survivors compared to siblings (all p < 0.05). Factors most strongly associated with the occurrence of CHC were multisystem LCH, multifocal bone involvement, and involvement of the pituitary gland. CONCLUSIONS More than half of long-term LCH survivors suffered from one or more CHC and were affected considerably more than siblings. IMPLICATIONS FOR CANCER SURVIVORS LCH survivors in follow-up care should be screened especially for cardiovascular, endocrine, musculoskeletal, and digestive conditions
