Objective: Transitional care in surgical neurooncology is poorly studied. However, this period is pivotal, since it allows the patient to be empowered in his or her disease management. Here, the authors describe the experience of the Necker-Enfants Malades and the Sainte-Anne Hospital collaboration., Methods: The mixed transitional consultations started in September 2019 in a dedicated space for transitional care, named the "La Suite" department, located in the Necker-Enfants Malades Hospital, Paris, France. The authors organized planned consultations to schedule the clinical and radiological follow-up in the adult neurosurgical department but also emergency consultations to manage tumor recurrence in young adult patients. Transitional care was performed jointly by pediatric and adult neurosurgeons who have developed clinical and research skills in the field of surgical neurooncology. Neuropathological analysis was performed by a neuropathologist who is specialized in pediatric and adult neurooncology., Results: Fourteen patients benefited from a mixed transitional consultation. All of them accepted to start their management in an adult neurosurgical environment. Eleven patients (78.6%) for whom the disease was controlled benefited from a planned consultation. Three patients (21.4%) required rapid neurosurgical management for a tumor recurrence (n = 2) or for a new primary CNS tumor (n = 1) and benefited from an emergency consultation., Conclusions: For adult patients harboring a brain tumor during childhood or adolescence, the authors suggest that neurosurgeons specialized in adult surgical neurooncology with a full knowledge in pediatric neurooncology will combine the required skills to optimize care management for these patients within a dedicated multidisciplinary organization framework.

Purpose To propose and validate a modified pediatric intracerebral hemorrhage (PICH) (mPICH) score and to compare its association with functional outcome to that of the original PICH score. Materials and Methods Data from prospectively included patients were retrospectively analyzed. Consecutive patients with nontraumatic PICH who had undergone clinical follow-up were included. The study population was divided into a development cohort (2008-2012, n = 100) and a validation cohort (2013-2016, n = 43). An mPICH score was developed after variables associated with poor outcome were identified at multivariate analysis (King's Outcome Scale for Childhood Head Injury score < 5a) in the development cohort. The accuracy of the score for prediction of poor outcome was evaluated (sensitivity, specificity). Discrimination and calibration of associations between the mPICH score and poor outcome cohorts were assessed (C statistics, Hosmer-Lemeshow test). Results The mPICH score assessed as follows: brain herniation, four points; altered mental status, three points; hydrocephalus, two points; infratentorial PICH, two points; intraventricular hemorrhage, one point; PICH volume greater than 2% of total brain volume, one point. An mPICH score greater than 5 was associated with severe disability or worse, with sensitivity of 97% (95% confidence interval [CI]: 83%, 100%) and specificity of 61% (95% CI: 49%, 73%). The C statistic was 0.81 (95% CI: 0.73, 0.89). In the validation cohort, sensitivity and specificity were 95.2% (95% CI: 76%, 99%) and 77% (95% CI: 55%, 92%), respectively. There was no significant difference between the observed and predicted risks of poor outcome (P = .46). Conclusion An mPICH score was developed as a simple clinical and imaging grading scale for acute prognosis in patients with PICH. © RSNA, 2017.
