Shared decision-making in pediatric palliative care in the Netherlands.

Shared decision-making (SDM) is a process in which health care professionals (HCPs) involve parents and children - when appropriate- to decide together on future treatment. These decisions are based on values that are important for the family, goals of care and preferences for future care and treatment. Elucidation of these values and preferences is preferably done early in the disease trajectory via so-called Advance Care Planning (ACP) conversations. In the Netherlands, ACP and SDM are being adopted by most health care professionals. This has happened only recently. Ten years ago, ACP and SDM were unknown concepts for the vast majority of Dutch HCPs. Today, interest in these conversational approaches is booming in both daily practice and in research. This rise has been reinforced by two recent major advancements in Dutch pediatric palliative care: the Individual Care Plan (ICP) and the Dutch Evidence-Based Guideline on Pediatric Palliative Care (DGPPC). Despite this positive evolution, a lot of work is still ahead. ACP and SDM demand a change in mindset from the traditional paternalistic approach by which the HCP 'knows what is best for this child' to a more humble and open approach in which (non-medical) factors that are important to the child and family and may influence the final treatment decision. Such changes in mindset don't happen overnight. In this article we describe the situation of pediatric palliative care in the Netherlands, with focus on the recent evolution of ACP and SDM.

Digital health tools for pain monitoring in pediatric oncology: a scoping review and qualitative assessment of barriers and facilitators of implementation.

PURPOSE: We aimed to systematically identify and characterize existing digital health tools for pain monitoring in children with cancer, and to assess common barriers and facilitators of implementation. METHODS: A comprehensive literature search (PubMed, Cochrane, Embase, and PsycINFO) was carried out to identify published research on mobile apps and wearable devices focusing on acute and/or chronic pain in children (0-18 years) with cancer (all diagnoses) during active treatment. Tools had to at least include a monitoring feature for one or more pain characteristic(s) (e.g., presence, severity, perceived cause interference with daily life). Project leaders of identified tools were invited for an interview on barriers and facilitators. RESULTS: Of 121 potential publications, 33 met inclusion criteria, describing 14 tools. Two methods of delivery were used: apps (n=13), and a wearable wristband (n=1). Most publications focused on feasibility and acceptability. Results of interviews with project leaders (100% response rate), reveal that most barriers to implementation were identified in the organizational context (47% of barriers), with financial resources and insufficient time available mentioned most often. Most factors that facilitated implementation related to end users (56% of facilitators), with end-user cooperation and end-user satisfaction mentioned most often. CONCLUSIONS: Existing digital tools for pain in children with cancer were mostly apps directed at pain severity monitoring and little is still known about their effectiveness. Paying attention to common barriers and facilitators, especially taking into account realistic funding expectations and involving end users during early stages of new projects, might prevent evidence based interventions from ending up unused.

Prevalence and risk factors of hypothalamic-pituitary dysfunction in infant and toddler childhood brain tumor survivors.

OBJECTIVE: Childhood brain tumor survivors (CBTS) are at risk to develop hypothalamic-pituitary (HP) dysfunction (HPD). The risk for HPD may vary between different age groups due to maturation of the brain and differences in oncologic treatment protocols. Specific studies on HPD in infant brain tumor survivors (infant-BTS, 0-1 years at diagnosis) or toddler brain tumor survivors (toddler-BTS, ≥1-3 years) have not been performed. PATIENTS AND METHODS: A retrospective nationwide cohort study in CBTS was performed. Prevalence and risk factors for HPD were compared between infant-, toddler-, and older-BTS. Subgroup analysis was performed for all non-irradiated CBTS (n = 460). RESULTS: In total, 718 CBTS were included, with a median follow-up time of 7.9 years. Overall, despite the less frequent use of radiotherapy (RT) in infants, no differences in the prevalence of HPD were found between the three groups. RT (OR: 16.44; 95% CI: 8.93-30.27), suprasellar tumor location (OR: 44.76; 95% CI: 19.00-105.49), and younger age (OR: 1.11; 95% CI: 1.05-1.18) were associated with HP dysfunction. Infant-BTS and toddler-BTS showed more weight gain (P < 0.0001) and smaller height SDS (P = 0.001) during follow-up. In non-irradiated CBTS, infant-BTS and toddler-BTS were significantly more frequently diagnosed with TSH-, ACTH-, and ADH deficiency, compared to older-BTS. CONCLUSION: Infant and toddler brain tumor survivors seem to be more vulnerable to develop HP dysfunction than older children. These results emphasize the importance of special infant and toddler brain tumor treatment protocols and the need for endocrine surveillance in children treated for a brain tumor at a young age.

Management and consequences of postoperative fluctuations in plasma sodium concentration after pediatric brain tumor surgery in the sellar region: a national cohort analysis.

PURPOSE: Severe fluctuations in plasma sodium concentration and plasma osmolarity, including central diabetes insipidus (CDI), may have significant influence on postoperative morbidity and mortality after pediatric brain tumor surgery.The aim of this study was to describe the frequency, severity and neurological consequences of these fluctuations in pediatric brain tumor survivors. METHODS: A retrospective, multi-institutional chart review was conducted among all children who underwent brain tumor surgery in the sellar or suprasellar region in seven university hospitals in the Netherlands between January 2004 and December 2013. RESULTS: Postoperative CDI was observed in 67.5% of 120 included children. Fluctuations of plasma sodium concentration ≥ 10 mmol/L/24 h during the first ten postoperative days were seen in 75.3% of patients with CDI, with a maximum delta of 46 mmol/L/24 h. When compared to patients without CDI, altered mental status occurred more frequently in patients with postoperative CDI (5.1 vs. 23.5% respectively, p = 0.009). Low plasma sodium concentration was related to altered mental status and the occurrence of seizures. Frequency and severity of fluctuations in plasma sodium concentration during the first ten postoperative days were significantly higher in patients with permanent CDI at last follow-up than in patients with transient CDI or without CDI (p = 0.007). CONCLUSION: Postoperative CDI is a common complication after pediatric brain tumor surgery in the sellar or suprasellar region. Extreme plasma sodium concentrations and large intra-day fluctuations still occur and seem to influence the postoperative neurological course. These results illustrate the need for intensive monitoring in a highly experienced center.

[Paediatric palliative care: multidisciplinary and pro-active]. / Kinderpalliatieve zorg: multidisciplinair en proactief.

Every child with a life-limiting or threatening illness, and his or her family, has a right to palliative care. Palliative care is not limited to end-of-life care, but starts from the moment of diagnosis and is independent of whether there are curative options. To optimise quality of life of both the child and the family, the emphasis of care should be on both somatic and psychosocial and spiritual aspects from the very start, and goals should be set together with the child and the family. A multidisciplinary and pro-active approach is essential if this is to be achieved. It is, therefore, strongly recommended that at least every academic hospital should have a multidisciplinary paediatric palliative care team.

Unexpected overnight stay following ENT day-case surgery: a 5-year audit.

Unexpected overnight stay following ENT day-case surgery: a 5-year audit. PROBLEMS/OBJECTIVES: Recent decades have seen a steady reduction in the average duration of hospitalization for all surgical patients, including those undergoing ENT procedures. Correspondingly, the proportion of day surgeries relative to in-patient surgeries has progressively increased. In the present observational study, we aimed to evaluate the proportion of unplanned overnight stays following planned day surgeries in our ENT unit, and the major causes of these unexpected overnight admissions. METHODS: From databases, we collected data from all patients who underwent ENT day-case surgery in Ziekenhuis Oost- Limburg between January 2008 and December 2013. RESULTS: A total of 10,440 patients underwent ENT day-case surgery during this period. The overall rate of unexpected overnight admission was 1.86%, with these overnight admissions most commonly due to anaesthetic (46.91%), surgical (19.59%), and organizational (17.01%) reasons. The types of ENT surgery at the greatest risk for prolonged hospitalisation were hemithyroidectomy (12.50%), tympanoplasty (12.15%), and uvulopalatopharyngoplasty (UPPP) (7.81%). We further identified a clear difference in the rate of unexpected overnight stay between surgery scheduled in the morning (1.17%) versus in the afternoon (12.98%). CONCLUSIONS: Our present findings highlight the various reasons for unexpected overnight admission after day-case surgery. To reduce the rate of unexpected overnight stays, we need to better understand these different reasons to support the ongoing search for possible solutions.

Development of clinical practice guidelines for supportive care in childhood cancer--prioritization of topics using a Delphi approach.

INTRODUCTION: Currently, very few guidelines for supportive care for children with cancer exist. In the Netherlands, nationwide guidelines are over 10 years old and mostly based on expert opinion. Consequently, there is growing support and need for clinical practice guidelines (CPGs), which ought to be developed with a well-defined methodology and include a systematic search of literature, evidence summaries, and a transparent description of the decision process for the final recommendations. Development of CPGs is time consuming; therefore, it is important to prioritize topics for which there is the greatest clinical demand. OBJECTIVES: This study aims to prioritize childhood cancer supportive care topics for development of CPGs. METHODS: A Delphi survey consisting of two rounds was conducted to prioritize relevant childhood cancer supportive care topics for the development of CPGs. A group of experts comprising 15 pediatric oncologists, 15 pediatric oncology nurses, and 15 general pediatricians involved in care for childhood cancer patients were invited to participate. All relevant supportive care topics in childhood cancer were rated. RESULTS: In both rounds, 36 panellists (82%) responded. Agreement between panellists was very good, with an intraclass correlation coefficient of 0.918 (95% confidence interval (CI) = 0.849-0.966, p < 0.001) in round 2. The ten topics with the highest score in the final round were infection, sepsis, febrile neutropenia, pain, nausea/vomiting, restrictions in daily life and activities, palliative care, procedural sedation, terminal care, and oral mucositis. CONCLUSION: We successfully used a Delphi survey to prioritize childhood cancer supportive care topics for the development of CPGs. This is a first step towards uniform and evidence-based Dutch guidelines in supportive care in childhood cancer. Even though performed nationally, we believe that this study can also be regarded as an example starting point for international development of CPGs in the field of supportive care in cancer or any other field for that matter.

The importance of microsurgery in childhood meningioma: a case report.

INTRODUCTION: Although meningiomas are frequently diagnosed in adults, it is a rare (intracranial) tumor in the pediatric population, with an incidence of 0.06/100,000. The pathology and treatment of meningiomas in adulthood has been a topic of increasing investigation. So far, the treatment of pediatric meningiomas has been extrapolated from these results. The question remains, however, whether translation of adult meningioma data into the childhood population is legitimate. METHODS: We present the case of a 3-year-old girl diagnosed with an intraventricular malignant meningioma and type 2 neurofibromatosis. She was operated on multiple times to achieve complete resection and received adjuvant chemotherapy. Since, she has been stable with no neurological sequelae and/or recurrence of the meningioma. CONCLUSION: Pediatric meningiomas are rare tumors and differ from their adult counterparts in various aspects. We believe that gross total resection of meningioma in the pediatric population, when possible, is the treatment of choice. In the event of a subtotal resection, repeat resection is recommended. Any adjuvant treatment with chemotherapy or radiation therapy should be carefully considered during multidisciplinary meetings.

Specific medical and surgical treatment for chronic inflammatory diseases in children.

Treatment for chronic inflammatory conditions in children should take into account the specific pathophysiological and clinical processes underlying these disorders. These guidelines provide a framework for both the medical and surgical treatment of chronic inflammatory diseases such as otitis media, allergic rhinitis and chronic rhinosinusitis, chronic inflammation of tonsils and adenoids, and laryngitis. In addition, the role of vaccinations and immunomodulatory therapies is discussed. Whenever possible, the evidence levels for specific treatments comply with the Oxford Levels of Evidence.

Information disclosure to terminally ill patients and their relatives: self-reported practice of Belgian clinical specialists and general practitioners.

Objective of this study is to examine physicians' practices regarding information disclosure to terminally ill patients and to their relatives, without informing the patient. A questionnaire had been sent to a random sample of 3014 Belgian physicians from different specialties frequently involved in end-of-life care. Responses were analysed using weighted percentages, Chi-square, Mann-Whitney U-tests and a multivariate ordinal logistic regression. Response rate was 58%. Both clinical specialists and general practitioners (GPs) discuss most topics related to terminal illness with their patients except end-of-life hastening options, spirituality, life expectancy and options to withhold/withdraw life-sustaining treatment. The topics which most physicians always discuss with relatives without informing the patient are the aim of treatment, palliative care and incurability. There is a significant difference between clinical specialists and GPs. Clinical specialists and GPs discuss most end-of-life topics with the patient but omit important issues such as end-of-life hastening options and life-expectancy.

Different anthracycline derivates for reducing cardiotoxicity in cancer patients.

BACKGROUND: The use of anthracycline chemotherapy is limited by the occurrence of cardiotoxicity. In an effort to prevent this cardiotoxicity, different anthracycline derivates have been studied. OBJECTIVES: The primary objective was to determine the occurrence of cardiotoxicity with the use of different anthracycline derivates in cancer patients. SEARCH STRATEGY: We searched the databases of the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 1, 2005), MEDLINE (1966 to April 2005) and EMBASE (1980 to April 2005). In addition, we searched reference lists of relevant articles, conference proceedings and ongoing trials databases. SELECTION CRITERIA: Randomised controlled trials (RCTs) in which different anthracycline derivates were compared in cancer patients (children and adults). DATA COLLECTION AND ANALYSIS: Two authors independently performed the study selection, quality assessment and data-extraction including adverse effects. MAIN RESULTS: We identified five RCTs of varying quality addressing epirubicin versus doxorubicin (1036 patients) with the same dose. The meta-analysis showed no evidence for a significant difference in the occurrence of clinical heart failure between the treatment groups (RR = 0.36, 95% CI 0.12 to 1.11). However, there is some suggestion of a lower rate of clinical heart failure in patients treated with epirubicin. We identified two RCTs with varying quality addressing liposomal-encapsulated doxorubicin versus conventional doxorubicin (521 patients). The meta-analysis showed a significantly lower rate of both clinical heart failure and clinical and subclinical heart failure combined in patients treated with liposomal-encapsulated doxorubicin (RR = 0.20, 95% CI 0.05 to 0.75 and RR = 0.38, 95% CI 0.24 to 0.59 respectively). It should be noted that in one of the studies patients in the liposomal-encapsulated doxorubicin group received a higher cumulative anthracycline dose than patients in the doxorubicin group. For the other possible combinations of different anthracycline derivates only one RCT was identified. AUTHORS' CONCLUSIONS: We are not able to favour either epirubicin or doxorubicin when given with the same dose. Based on the currently available evidence on heart failure, we conclude that in adults with a solid tumour liposomal-encapsulated doxorubicin should be favoured over doxorubicin. For both epirubicin versus doxorubicin and liposomal-encapsulated doxorubicin versus conventional doxorubicin no conclusions can be made about the effects of treatment in children treated with anthracyclines and also not in patients diagnosed with leukaemia. More research is needed. For other combinations of anthracycline derivates not enough evidence was available to make definitive conclusions about the occurrence of cardiotoxicity in patients treated with anthracyclines.

Near infrared reflectance spectroscopy for the fast identification of PVC-based films.

Near infrared (NIR) reflectance spectroscopy was used to develop a non-destructive and rapid qualitative method for the analysis of plastic films used by the pharmaceutical industry for blistering. Three types of films were investigated: 250 microm PVC [poly(vinyl chloride)] films, 250 microm PVC films coated with 40 g m(-2) of PVDC [poly(vinylidene dichloride)] and 250 microm PVC films coated with 5 g m(-2) of TE (Thermoelast) and 90 g m(-2) of PVDC. Three analyses were carried out using different pre-treatment options and a PLS (partial least squares) algorithm. Each analysis was aimed at identifying one type of film and rejecting all types of false sample (different thickness, colour or layer). True and false samples from four plastics manufacturers were included in the calibration sets in order to obtain robust methods that were suitable regardless of the supplier. Specificity was demonstrated by testing validation sets against the methods. The tests showed 0% of type I (false negative identification) and 1% of type II errors (false positive identification) for the PVC method, 13 and 3%, respectively, for the PVC-PVDC method and no error for the PVC-TE-PVDC method. Type II errors, mostly due to the slight sensitivity of the methods to film thickness, are easily corrected by simple thickness measurements. This study demonstrates that NIR spectroscopy is an excellent tool for the identification of PVC-based films. The three methods can be used by the pharmaceutical industry or plastics manufacturers for the quality control of films used in blister packaging.

USAGE: a web-based approach towards the analysis of SAGE data. Serial Analysis of Gene Expression.

MOTIVATION: SAGE enables the determination of genome-wide mRNA expression profiles. A comprehensive analysis of SAGE data requires software, which integrates (statistical) data analysis methods with a database system. Furthermore, to facilitate data sharing between users, the application should reside on a central server and be accessed via the internet. Since such an application was not available we developed the USAGE package. RESULTS: USAGE is a web-based application that comprises an integrated set of tools, which offers many functions for analysing and comparing SAGE data. Additionally, USAGE includes a statistical method for the planning of new SAGE experiments. USAGE is available in a multi-user environment giving users the option of sharing data. USAGE is interfaced to a relational database to store data and analysis results. The USAGE query editor allows the composition of queries for searching this database. Several database functions have been included which enable the selection and combination of data. USAGE provides the biologist increased functionality and flexibility for analysing SAGE data. AVAILABILITY: USAGE is freely accessible for academic institutions at http://www.cmbi.kun.nl/usage/. The source code of USAGE is freely available for academic institutions on request from the first author.

Are clinical parameters valuable prognostic factors in childhood primitive neuroectodermal tumors? A multivariate analysis of 105 cases.

BACKGROUND: Medulloblastoma is one of the most frequent brain tumors in children. Long-term survivors are often confronted with serious late sequelae, caused by the therapy. Therefore, prognostic markers must be identified that allow the children to be assigned to different treatment schedules according to their predicted outcome. PATIENTS AND METHODS: The medical data of 110 children with a medulloblastoma or central primitive neuroectodermal tumor (PNET), that were admitted to the Emma Kinderziekenhuis in Amsterdam were analyzed by univariate and multivariate analyses. RESULTS: In univariate analysis the following characteristics had a significant influence on progression free survival (PFS): (a) presence of meningeal metastases at the time of diagnosis, (b) presence of tumor cells in the cerebrospinal fluid before or after surgery, (c) extent of resection, (d) necessity for permanent cerebrospinal fluid (CSF) shunting and (e) radiation dose to the posterior fossa. On multivariate analysis only the presence of metastases and the radiation dose to the posterior fossa retained significance. CONCLUSION: At the time of diagnosis, no reliable clinical prognostic markers are available for the majority of patients. Further molecular studies must be undertaken to identify such prognostic factors.

Genes differentially expressed in medulloblastoma and fetal brain.

Serial analysis of gene expression (SAGE) was used to identify genes that might be involved in the development or growth of medulloblastoma, a childhood brain tumor. Sequence tags from medulloblastoma (10229) and fetal brain (10692) were determined. The distributions of sequence tags in each population were compared, and for each sequence tag, pairwise chi2 test statistics were calculated. Northern blot was used to confirm some of the results obtained by SAGE. For 16 tags, the chi2 test statistic was associated with a P value < 10(-4). Among those transcripts with a higher expression in medulloblastoma were the genes for ZIC1 protein and the OTX2 gene, both of which are expressed in the cerebellar germinal layers. The high expression of these two genes strongly supports the hypothesis that medulloblastoma arises from the germinal layer of the cerebellum. This analysis shows that SAGE can be used as a rapid differential screening procedure.

Interstitial lung disease more than 40 years after a 5 year occupational exposure to talc.

A 62 yr old woman was initially diagnosed with sarcoidosis until a thoracoscopic biopsy revealed the presence of numerous birefringent particles in fibrotic areas of the centrilobular lung zones. These particles were examined by electron microscopy and X-ray spectrometry and characterized as impure talc. Further inquiry into her occupational history revealed that she had worked from the age of 14-18 yrs in a factory making rubber hoses, where she had had an intense exposure to talc. There was no evidence of silicosis or asbestosis, and other significant causes of interstitial lung disease were excluded. This case emphasizes the importance of a thorough occupational history, which may reveal a remote and forgotten exposure to a significant cause of interstitial lung disease. Although this presentation of talcosis is unusual, this case suggests that even a relatively short, but presumably intense exposure to talc more than 40 yrs previously may be a cause of progressive lung fibrosis.

Long-term neuro-endocrine sequelae after treatment for childhood medulloblastoma.

The occurrence of neuro-endocrine deficiencies following craniospinal irradiation for medulloblastoma is well known, but data concerning the spectrum and prevalence of endocrine abnormalities in adulthood are scarce. We studied endocrine function in 20 (median age 25 years) adult subjects, 8-25 years (median 16 years) after therapy. The radiation dose to the whole cranium and spinal axis was 35 +/- 2.6 Gray (mean +/- standard deviation) with a boost to the posterior fossa of 18 +/- 3.7 Gray. 13 subjects had received additional chemotherapy. In 15 of 20 (75%) subjects, endocrine abnormalities were observed. In 14 (70%), growth hormone (GH) secretion was impaired; 7 (35%) subjects had an absolute GH deficiency, while 7 (35%) showed subnormal responses to insulin-induced hypoglycaemia. In contrast, only 20% (4) of these subjects showed impairment of the hypothalamus-pituitary-thyroid (HPT) axis, while 15% (3) showed central impairment of hypothalamus-pituitary-gonadal (HPG) function. Central impairment of the HPG axis was associated with impaired GH secretion in all cases. Central adrenal insufficiency was not observed. Basal levels of prolactin were normal in all subjects. Young age at treatment was a determinant of GH deficiency in adulthood (P = 0.014). Neither post-treatment interval, nor the use of chemotherapy were determinants of central endocrine impairment in adulthood. In long-term survivors of medulloblastoma, GH deficiency has a high prevalence. In contrast, impairment of the HPG and HPT axis is less common, while central adrenal insufficiency was not observed.

Relief of sleep apnoea after treatment of acromegaly: report of three cases and review of the literature.

Sleep apnoea syndrome (SAS) is common in acromegalic patients. Occasionally, the relief of apnoeas after treatment of the acromegaly has been documented. We report the cases of three patients with acromegaly and severe obstructive sleep apnoea, who demonstrated a manifest improvement (respiratory disturbance index (RDI) <20) after treatment with octreotide, indicating that this drug may be effective in this disturbance. In one case, SAS disappeared although the growth hormone level was not fully normalized. This raises the intriguing hypothesis that octreotide has an effect on respiratory control or on the upper airway, that is not directly related to its action on production of growth hormone.

Ifosfamide in the treatment of pediatric malignancies.

Neuroblastomas, nephroblastomas, malignant mesenchymal tumors, including rhabdomyosarcomas, Ewing's sarcomas, osteosarcomas, brain tumors, and non-Hodgkin's lymphomas respond to ifosfamide monotherapy. Ifosfamide has found an established place in the treatment of these pediatric malignancies. Ifosfamide has been shown to be an especially valuable agent in brain tumors in patients with a poor-prognosis medulloblastoma. The combination of ifosfamide with other cytotoxic drugs is more effective than ifosfamide medication alone. Ifosfamide has to be given with mesna to prevent bladder toxicity, but other toxic side effects, such as neurotoxicity, nephrotoxicity, and gonadal damage, are more difficult to prevent. Ifosfamide has proven to be an important asset in the treatment of cancer in children.
