Pediatric oncologists' perspectives on the use of complementary medicine in pediatric cancer patients in Switzerland: A national survey-based cross-sectional study.

BACKGROUND: There is a widespread use of complementary therapies among pediatric cancer patients. Previous studies provided evidence that communication between pediatric oncologists (POs) and patients/families about the use of these therapies is often incomplete. Furthermore, nationwide studies on this topic are rare. AIMS: We assessed POs' perspectives on the use of complementary medicine (CM) in Switzerland, on the basis of an edited survey previously used in a nationwide study. METHODS AND RESULTS: A link to an online survey was sent by e-mail to each of the fifty-two eligible pediatric oncologists in all nine Swiss Pediatric Oncology Group (SPOG) centers. Eligible respondents were board-certified (Switzerland or abroad) POs currently working at a SPOG center. The survey was available for a total period of 2 months. We received 29 filled questionnaires (overall response rate: 56%). Most POs (59%) indicated that they ask more than 50% of their patients about CM use. Frequent reasons for not asking about the use of CM were i) forgetting to ask (55%), ii) lack of knowledge on the subject (31%), and iii) lack of time (24%). More than every second PO (55%) reported having a lack of knowledge on the subject. A majority of POs (66% to 76%) indicated interest in learning more about specific CM topics (cannabinoids, hypnosis and relaxation, music therapy, herbal medicine, acupuncture, meditation, and yoga). More information and specific training opportunities on the use of CM was deemed important by 76% to 97% of POs. CONCLUSION: POs working in Switzerland identify complementary therapies as an important subject. Swiss POs are willing to acquire more knowledge on CM. More training seems to be necessary in order to increase awareness about the topic, to enhance communication about complementary therapies and thus to improve patient care.

A single supratentorial high-grade neuroepithelial tumor with two distinct BCOR mutations, exceptionally long complete remission and survival.

Here, we present a patient with high-grade neuroepithelial tumors with mutations in the BCL6 corepressor BCOR (HGNET-BCOR), a rare, highly malignant brain tumor with poor prognosis. The patient underwent gross total tumor resection (GTR), high-dose chemotherapy, and, after local relapse, GTR, proton radiation, and chemotherapy. After a 7.5 year-long complete remission, the tumor recurred locally, was treated by GTR, and responded to temozolomide treatment. In addition to an internal tandem duplication in BCOR common to the majority of HGNET-BCOR cases, molecular analysis revealed a second BCOR mutation in this tumor: a frame shift mutation. The combination of these mutations was associated with relatively low BCOR expression compared to other HGNET-BCOR cases.

The conceptual understanding of pediatric palliative care: a Swiss healthcare perspective.

BACKGROUND: Health care providers' perception of pediatric palliative care might negatively influence timely implementation. The aim of the study was to examine understanding of and attitudes towards pediatric palliative care from the perspective of health care providers working in pediatric oncology in Switzerland to promote the timely implementation of pediatric palliative care. METHODS: Five mixed focus groups were conducted with 29 health care providers (oncologists, nurses, psychologists, and social workers) at five Swiss pediatric oncology group centers. The focus group interviews were analyzed using thematic coding. RESULTS: Most participants associated pediatric palliative care with non-curative treatment. They regularly reported difficulties in addressing palliative care services to families due to the strong stigma surrounding this term. They also thought that the notion of palliative care is very much linked to a policy context, and difficult to reconcile with children's everyday life. To overcome these obstacles many participants used synonyms such as comfort or supportive care. A few providers insisted on the need of using palliative care and reported the importance of positive "word of mouth". CONCLUSIONS: The use of synonyms might be a pragmatic approach to overcome initial barriers to the implementation of palliative care in pediatrics. However, this tactic might ultimately prove to be ineffective as these terms might acquire the same negative connotations as palliative care. Positive word-of-mouth by satisfied families and healthcare providers might be a more sustainable way to advocate for pediatric palliative care than replacing it with a euphemistic term.

Patterns of paediatric end-of-life care: a chart review across different care settings in Switzerland.

BACKGROUND: Paediatric end-of-life care is challenging and requires a high level of professional expertise. It is important that healthcare teams have a thorough understanding of paediatric subspecialties and related knowledge of disease-specific aspects of paediatric end-of-life care. The aim of this study was to comprehensively describe, explore and compare current practices in paediatric end-of-life care in four distinct diagnostic groups across healthcare settings including all relevant levels of healthcare providers in Switzerland. METHODS: In this nationwide retrospective chart review study, data from paediatric patients who died in the years 2011 or 2012 due to a cardiac, neurological or oncological condition, or during the neonatal period were collected in 13 hospitals, two long-term institutions and 10 community-based healthcare service providers throughout Switzerland. RESULTS: Ninety-three (62%) of the 149 reviewed patients died in intensive care units, 78 (84%) of them following withdrawal of life-sustaining treatment. Reliance on invasive medical interventions was prevalent, and the use of medication was high, with a median count of 12 different drugs during the last week of life. Patients experienced an average number of 6.42 symptoms. The prevalence of various types of symptoms differed significantly among the four diagnostic groups. Overall, our study patients stayed in the hospital for a median of six days during their last four weeks of life. Seventy-two patients (48%) stayed at home for at least one day and only half of those received community-based healthcare. CONCLUSIONS: The study provides a wide-ranging overview of current end-of-life care practices in a real-life setting of different healthcare providers. The inclusion of patients with all major diagnoses leading to disease- and prematurity-related childhood deaths, as well as comparisons across the diagnostic groups, provides additional insight and understanding for healthcare professionals. The provision of specialised palliative and end-of-life care services in Switzerland, including the capacity of community healthcare services, need to be expanded to meet the specific needs of seriously ill children and their families.

Palliative care in Swiss pediatric oncology settings: a retrospective analysis of medical records.

PURPOSE: This study examined the provision of palliative care and related decision-making in Swiss pediatric oncology settings. The aim was to determine if and when children who died from cancer received palliative care, whether there were differences by cancer diagnosis, and inclusion of children in decision-making regarding palliative care. METHODS: Using a standardized data extraction form, a retrospective review of medical records of deceased pediatric patients was conducted. The form captured information on demographics, diagnosis, relapse(s), treatments, decision-making during palliative care, and circumstances surrounding a child's death. RESULTS: For 170 patients, there was information on whether the child received palliative care. Among those, 38 cases (22%) did not receive palliative care. For 16 patients, palliative care began at diagnosis. The mean duration of palliative care was 145 days (Mdn = 89.5, SD = 183.4). Decision to begin palliative care was discussed solely with parent(s) in 60.9% of the cases. In 39.1%, the child was involved. These children were 13.6 years of age (SD = 4.6), whereas those not included were 7.16 years old (SD = 3.9). Leukemia patients were less likely to receive palliative care than the overall sample, and patients with CNS neoplasms received palliative care for a longer time than other patients. CONCLUSIONS: There are still high numbers of late or non-referrals, and even children older than 12 years were not involved in decision-making regarding palliative care. These results do not align with international organizational guidelines which recommend that palliative care should begin at diagnosis.

Parents' and Physicians' Perceptions of Children's Participation in Decision-making in Paediatric Oncology: A Quantitative Study.

The goal is to present how shared decision-making in paediatric oncology occurs from the viewpoints of parents and physicians. Eight Swiss Pediatric Oncology Group centres participated in this prospective study. The sample comprised a parent and physician of the minor patient (<18 years). Surveys were statistically analysed by comparing physicians' and parents' perspectives and by evaluating factors associated with children's actual involvement. Perspectives of ninety-one parents and twenty physicians were obtained for 151 children. Results indicate that for six aspects of information provision examined, parents' and physicians' perceptions differed. Moreover, parents felt that the children were more competent to understand diagnosis and prognosis, assessed the disease of the children as worse, and reported higher satisfaction with decision-making on the part of the children. A patient's age and gender predicted involvement. Older children and girls were more likely to be involved. In the decision-making process, parents held a less active role than they actually wanted. Physicians should take measures to ensure that provided information is understood correctly. Furthermore, they should work towards creating awareness for systematic differences between parents and physicians with respect to the perception of the child, the disease, and shared decision-making.

Participation in pediatric oncology: views of child and adolescent patients.

OBJECTIVE: The aim of the present study is to explore patient's perspectives in pediatric oncology on participation in discussions and decision-making surrounding their cancer diagnosis. METHODS: Seventeen patients between 9 and 17 years of age receiving treatment at centers of the Swiss Pediatric Oncology Group were interviewed for this study. Their interview data was analyzed qualitatively to identify themes with regard to participation in medical communication and/or decision-making. RESULTS: Participants highlighted how their roles in health care discussions varied from direct participation to indirect involvement. Overall, there were fewer accounts of involvement in decision-making than in overall health care discussions. Challenges with regard to completely understanding the information provided and making decisions were identified. Participants also discussed situations when they were not involved in medical communication or decision-making. While they generally valued their participation, the preferred level of involvement oscillated between participants as well as within one and the same child across time. CONCLUSIONS: The complex pattern of participation found in this study calls for a flexible model of involving children and adolescents in health care that accounts for the varying roles and preferences that they manifest. A patient may appreciate active involvement in some decisions while choosing to remain in the background for others. Copyright © 2015 John Wiley & Sons, Ltd.

Socioeconomic Status and Childhood Leukemia Incidence in Switzerland.

Socioeconomic status (SES) discrepancies exist for child and adult cancer morbidity and are a major public health concern. In this Swiss population-based matched case-control study on the etiology of childhood leukemia, we selected the cases from the Swiss Childhood Cancer Registry diagnosed since 1991 and the controls randomly from census. We assigned eight controls per case from the 1990 and 2000 census and matched them by the year of birth and gender. SES information for both cases and controls was obtained from census records by probabilistic record linkage. We investigated the association of SES with childhood leukemia in Switzerland, and explored whether it varied with different definitions of socioeconomic status (parental education, living condition, area-based SES), time period, and age. In conditional logistic regression analyses of 565 leukemia cases and 4433 controls, we found no consistent evidence for an association between SES and childhood leukemia. The odds ratio comparing the highest with the lowest SES category ranged from 0.95 (95% CI: 0.71-1.26; P trend = 0.73) for paternal education to 1.37 (1.00-1.89; P trend = 0.064) for maternal education. No effect modification was found for time period and age at diagnosis. Based on this population-based study, which avoided participation and reporting bias, we assume the potential association of socioeconomic status and childhood leukemia if existing to be small. This study did not find evidence that socioeconomic status, of Switzerland or comparable countries, is a relevant risk factor or strong confounder in etiological investigations on childhood leukemia.

High weekly doses of liposomal amphotericin B as secondary prophylaxis after cerebral aspergillosis in a paediatric patient.

A paediatric patient treated for acute lymphoblastic leukaemia developed cerebral abscesses caused by Aspergillus fumigatus. After surgical draining voriconazole treatment was started. The patient developed a Steven-Johnson syndrome and treatment was switched to L-AmB. The patient developed no new fungal lesions and L-AmB treatment was continued until the end of the therapy. Complete remission was achieved without neurological consequences. High dose L-AmB represents an alternative for secondary prophylaxis of invasive fungal infections in patients intolerant to azoles.

Information provision and information needs in adult survivors of childhood cancer.

BACKGROUND: Knowledge about their past medical history is central for childhood cancer survivors to ensure informed decisions in their health management. Knowledge about information provision and information needs in this population is still scarce. We thus aimed to assess: (1) the information survivors reported to have received on disease, treatment, follow-up, and late effects; (2) their information needs in these four domains and the format in which they would like it provided; (3) the association with psychological distress and quality of life (QoL). PROCEDURE: As part of the Follow-up survey of the Swiss Childhood Cancer Survivor Study, we sent a questionnaire to all survivors (≥18 years) who previously participated to the baseline survey, were diagnosed with cancer after 1990 at an age of <16 years. RESULTS: Most survivors had received oral information only (on illness: oral: 82%, written: 38%, treatment: oral: 79%, written: 36%; follow-up: oral: 77%, written: 23%; late effects: oral: 68%, written: 14%). Most survivors who had not previously received any information rated it as important, especially information on late effects (71%). A large proportion of survivors reported current information needs and would like to receive personalized information especially on late effects (44%). Survivors with higher information needs reported higher psychological distress and lower QoL. CONCLUSIONS: Survivors want to be more informed especially on possible late effects, and want to receive personalized information. Improving information provision, both qualitatively and quantitatively, will allow survivors to have better control of their health and to become better decision makers.

Family characteristics as risk factors for childhood acute lymphoblastic leukemia: a population-based case-control study.

BACKGROUND: To date, few risk factors for childhood acute lymphoblastic leukemia (ALL) have been confirmed and the scientific literature is full of controversial "evidence." We examined if family characteristics, particularly maternal and paternal age and number of older siblings, were risk factors for childhood acute lymphoblastic leukemia (ALL). METHODOLOGY/PRINCIPAL FINDINGS: In this population-based nationwide matched case-control study, patients 0-14 years of age with ALL diagnosed 1991-2006 and registered in the Swiss Childhood Cancer Registry were linked with their census records of 1990 and 2000. Eight controls per case were selected from the census. The association between family characteristics and ALL was analyzed by conditional logistic regressions. We found that increasing maternal age was associated with incidence of ALL in the offspring (OR per 5-year increase in maternal age 1.18, 95% CI 1.05-1.31; p = 0.004), remaining stable (trend OR 1.14, 95% CI 0.99-1.31; p = 0.060) after adjustment for other risk factors. The association with paternal age was weaker (OR per 5-year increase 1.14, 95% CI 1.01-1.28, p = 0.032) and disappeared after adjustments. Number of older siblings was not associated with risk of ALL in the overall group of children aged 0-14 years at diagnosis. However, we found a negative trend between number of older siblings and ALL diagnosed at age 0-4 years (OR per sibling 0.85, 95% CI 0.68-1.06; p = 0.141) and a positive trend for ALL diagnosed at age 5-9 (OR 1.34, 95% CI 1.05-1.72; p = 0.019), with some evidence for an effect modification (p-value for interaction  = 0.040). CONCLUSIONS: As in other studies, increasing maternal, but not paternal age was associated with risk of ALL. We found only a weak association with the number of older siblings, suggesting a delay in disease manifestation rather than a decrease in incidence.

Sperm analysis of patients after successful treatment of childhood acute lymphoblastic leukemia with chemotherapy.

Survivors of childhood acute lymphoblastic leukemia (ALL) treated with radiotherapy are at risk for impaired fertility. Whether chemotherapy alone is also long-term gonadotoxic is unclear. We assessed gonadal function in 11 male ALL-survivors treated with the same chemotherapy regimen and compared sperm analysis to healthy men. While sex hormone levels were normal in all subjects, 5/11 survivors showed pathological sperm concentration and 4/11 a decreased total sperm count compared to WHO criteria. Compared to healthy controls, all quantitative parameters in semen analysis of survivors were decreased. This suggests that treatment with chemotherapeutic agents alone, even in moderate doses, might have a gonadotoxic effect.

Susceptibility of Escherichia coli strains isolated from outpatient children with community-acquired urinary tract infection in southern Switzerland.

BACKGROUND: Based on antimicrobial resistance patterns found in Swiss university hospitals, treatment with a third-generation cephalosporin is currently advised for Swiss children with urinary tract infection. OBJECTIVE: The aim of this study was to prospectively assess the susceptibility of Escherichia coli strains isolated from children with symptomatic community-acquired urinary tract infection. METHODS: The antimicrobial susceptibility of E coli strains causing symptomatic community-acquired urinary tract infections was assessed in outpatient children attending the emergency management unit at the Department of Pediatrics, Mendrisio and Bellinzona Hospitals, Switzerland. Strains from children receiving antimicrobial prophylaxis or prescribed antimicrobials in the previous 4 weeks were excluded. Clinical and Laboratory Standards Institute methods were used for culture and identification of pathogens. E coli susceptibility testing was performed using the disk diffusion technique. RESULTS: Strains from 100 consecutive outpatient children (73 girls, 27 boys; aged 5 weeks-17 years [median, 33 months]; 100% white) were assessed. High rates of ampicillin and cotrimoxazole resistance (39 and 21 strains, respectively) and low rates of nitrofurantoin resistance (4 strains) were identified. No resistance was identified for coamoxiclav or third-generation cephalosporins. CONCLUSIONS: In these Swiss outpatient children with symptomatic community-acquired urinary tract infection, without antimicrobial prophylaxis or recent prescription of antimicrobials, uropathogenic E coli strains resistant in vitro to ampicillin and cotrimoxazole were common. However, in vitro resistance to nitrofurantoin, coamoxiclav, and third-generation cephalosporins was uncommon.

Congenital self-healing langerhans cell histiocytosis with atrophic recovery of the skin: clinical correlation of an immunologic phenomenon.

The pathophysiology and pathogenesis of congenital self-healing Langerhans cell histiocytosis (CSHLCH) as well as that of the other types of Langerhans cell histiocytosis is not well understood. Some authors postulate deregulated immunologic mechanisms that result in overproduction of cytokines. We examined a neonate with disseminated papulonodular eruptions containing lymphoid aggregates of B lymphocytes in the chorial layer. The diagnosis of a CSHLCH was made and the follow-up showed a complete involution of the eruptions, leaving atrophic lesions in the sites corresponding to the initial findings. We discuss a possible imbalance of the immune response as a pathogenetic mechanism.
