Background and aims: During the first lockdown of the novel Coronavirus pandemic (COVID-19), we developed a teleconsultation model to replace in-person visits. We conducted a survey-based study with the aim to evaluate satisfaction and emotions of health workers (HWs), to assess the feasibility of teleconsultations and to evaluate technical issues. Methods: This is a prospective monocentric exploratory study in which data were collected from March until May 2020 in the Lyon Pediatric Hematology and Oncology institute (IHOPe). We realized synchronous, video-based consultations between HWs and pediatric patients, treated for blood or solid malignancies or blood benign diseases. Every HW completed an online, pseudo-anonymized questionnaire which covered technical aspects, data concerning satisfaction, perception of the quality of the interaction with the patient and emotions felt after the teleconsultation. A score was calculated for each aspect. In order to study the relationship between the scores, the correlation coefficient method was used. Results: Eleven specialists participated in the study and we selected 84 questionnaires. With a satisfaction rate of 74%, HWs felt mostly calm (80%), relaxed (70%), stress-free (69%) and relieved (65%). We calculated the following median scores: an overall satisfaction score of 6.67 (0-10), a global feeling score of 8.79 (3.33-10.00), and a quality score of 7.34 (2.50-10.00). A strong correlation between the quality of the teleconsultation and the satisfaction of the HWs has been highlighted (r = 0,588). Conclusion: Our series is an encouragingly positive experience from the perspective of the HWs, their feelings and perceptions.

Introduction: Posterior fossa ependymomas in children are associated with a poor prognosis. This retrospective study tries to determine prognostic factors for the outcomes and the quality of life. Material and Methods: Thirty-three patients with posterior fossa ependymomas were treated from 2002 to 2018. All patients had a cranio-spinal MRI and 3.12% were metastatic. Removal was complete in 29 patients (90.62%). All patients received a complementary treatment: 11patients chemotherapy, radiotherapy in 35 patients, 24 cases of neoadjuvant type and for recurrence in 11. Results: Average age was 5.8 years with a range from 9 months to 18 years. The sex ratio was 2.3 (M/F: 23/10). Sixteen patients had one recurrence (3 metastatic). 90% of the EpPCF were of the PFA group. Overall Survival was 65% with a mean follow-up of 8.4 and a median of 9 years. Twenty-one patients were alive (63.63%) at last follow-up. All were tumour-free according the MRI except 2 patients, 1 with a stable residue for 5 years and 1 in palliative treatment for metastatic recurrence for 5 years. Post-operative complications were as follow, facial nerve palsy in four cases (12.12%), swallowing disorders in three cases (9.09%), transient cerebellar syndrome in 4 cases (12.12%). Fifteen patients had normal schooling. Conclusion: Posterior fossa ependymomas are aggressive tumors. Complete surgical removal remains the most important prognostic factor even if responsible of sequels. Despite molecular studies and the expression of different genes, no obvious therapeutic target has yet emerged.
