Identifying the Roadblocks to Successful Pediatric Imaging Without Sedation or Anesthesia
Background: Modern imaging modalities allow for assessment of a wide array of medical conditions. Because it is difficult for young children to remain still during lengthy imaging studies, there is a need for sedation and general anesthesia (GA). A growing literature, however, suggests that there may be deleterious neurocognitive effects of sedation/GA in young children. As such, it is in our patients’ best interest to critically evaluate the use of sedation/GA.
Objective: To identify the roadblocks to obtaining clinical pediatric magnetic resonance imaging (MRI) exams without sedation/GA.
Materials and Methods: Participants included 63 parents/guardians of 5- to 9-year-old patients who underwent outpatient MRI; 54% of the patients were sedated (n=34) and 46% not sedated (n=29). Parents and nonsedated patients completed surveys to gauge their respective knowledge, preferences, and preparation for the MRI exam.
Results: The average scan duration was marginally significantly greater in sedated patients than nonsedated patients (p=0.06). Parents of sedated patients were significantly less likely to be interested in their child attempting a nonsedated scan (ppp=0.01) and practice in the mock scanner (p=0.01).
Conclusion: The roadblocks to nonsedated pediatric imaging include extended scan duration, parental preference, parental anxiety, and patient anxiety. These roadblocks may be overcome by decreasing scan duration, increasing parental education, and increasing child preparation
Neuroblastoma
The survival of patients with high-risk neuroblastoma has improved significantly with the use of intensive multimodality treatment regimens, including chemotherapy, surgery, radiation therapy, myeloablative chemotherapy followed by stem cell rescue, and immunotherapy. This report summarizes the current treatment strategies used in the COG and SIOP for children with neuroblastoma. The improved global collaboration and the adoption of a uniform International Neuroblastoma Risk Group Staging System will help facilitate comparison of homogeneous pretreatment cohorts across clinical trials. Future research strategies regarding the indications for and dosages of radiation therapy to the primary and metastatic sites, and the integration of meta-iodobenzyl guanidine therapy into the multimodal treatment program, are discussed
Bortezomib Inpatient Prescribing Practices in Free-Standing Children's Hospitals in the United States.
This study is a pharmacoepidemiologic description of pediatric bortezomib use. Exposure was identified through billing codes in patients admitted to US children's hospitals that participated with the Pediatric Health Information System between 2004 and 2013. Associated information on underlying diseases, demographics, institutional use, mortality, and physician type was collected. Exposure to bortezomib was identified in 314 patients. Hematologist/Oncologists prescribed half of the bortezomib used. Use increased during the study period. Inpatient volume was positively correlated with bortezomib utilization. Bortezomib use in pediatrics is increasing for a variety of diseases. Variation in use exists across institutions. Further studies are needed to characterize bortezomib's efficacy in pediatric diseases
Pantoprazole, an Inhibitor of the Organic Cation Transporter 2, Does Not Ameliorate Cisplatin‐Related Ototoxicity or Nephrotoxicity in Children and Adolescents with Newly Diagnosed Osteosarcoma Treated with Methotrexate, Doxorubicin, and Cisplatin
Significance of MYCN Amplification in International Neuroblastoma Staging System Stage 1 and 2 Neuroblastoma: A Report From the International Neuroblastoma Risk Group Database
Purpose Treatment of patients with localized neuroblastoma with unfavorable biologic features is controversial. To evaluate the outcome of children with low-stage MYCN-amplified neuroblastoma and develop a rational treatment strategy, data from the International Neuroblastoma Risk Group (INRG) database were analyzed. Patients and Methods The database is comprised of 8,800 patients. Of these, 2,660 patients (30%) had low-stage (International Neuroblastoma Staging System stages 1 and 2) neuroblastoma, known MYCN status, and available follow-up data. Eighty-seven of these patients (3%) had MYCN amplified tumors. Results Patients with MYCN-amplified, low-stage tumors had less favorable event-free survival (EFS) and overall survival (OS) than did patients with nonamplified tumors (53% +/- 8% and 72% +/- 7% v 90% +/- 1% and 98% +/- 1%, respectively). EFS and OS were statistically significantly higher for patients whose tumors were hyperdiploid rather than diploid (EFS, 82% +/- 20% v 37% +/- 21%; P = .0069; OS, 94% +/- 11% v 54% +/- 15%; P = .0056, respectively). No other variable had prognostic significance. Initial treatment consisted of surgery alone for 29 (33%) of 87 patients. Details of additional therapy were unknown for 14 patients. Twenty-two patients (25%) underwent surgery and moderate-intensity chemotherapy; another 22 underwent surgery, intensive chemotherapy, and radiation therapy. Nine of the latter 22 underwent stem cell transplantation. Survival in patients who received transplantation did not differ from survival in those who did not receive transplantation. Conclusion Among patients with low-stage, MYCN-amplified neuroblastoma, outcomes of patients with hyperdiploid tumors were statistically, significantly better than those with diploid tumors. The data suggest that tumor cell ploidy could potentially be used to identify candidates for reductions in therapy. Further study of MYCN-amplified, low-stage neuroblastoma is warranted
