[Pediatric medical evacuations from Reunion Island to metropolitan France]. / Évacuations sanitaires pédiatriques en oncologie et en hématologie de l'île de la Réunion vers la France métropolitaine.

BACKGROUND: The only French center for pediatric oncology and hematology outside of the metropolitan territory is in the Indian Ocean, in Saint Denis, on Reunion Island. It welcomes children from Reunion Island but also from Mayotte and neighboring countries. A quarter of them requires a secondary medical transfer to metropolitan France for specific technic care. METHOD: We conducted a retrospective single-center study of all pediatric medical evacuations that occurred between 2015 and 2019 from the pediatric oncology and hematology department of Reunion Island. The purpose of this study is to describe these transfers and the consequences of these care pathways for families and care teams. RESULTS: A total of 189 transfers took place for 105 children: 66 from Reunion Island, 17 from Mayotte and 22 were foreigners. In total, 92 % of the children received the medical care for which they were transferred to metropolitan France. Difficulties were reported: family for 26 % of them, social in 11 % of cases and medical in 10 % of medical records. CONCLUSIONS: This organization allows children in the Indian Ocean to benefit from similar care than metropolitan children. Many difficulties arise in connection with family and societal breakdowns caused by these transfers. These differences and difficulties are important to know to better accompany patients, families and caregivers in this stage of their medical pathways.

Varicella post-exposure management for pediatric oncology patients.

INTRODUCTION: The objective was to evaluate health care providers' (HCP) adherence to and efficacy of varicella post-exposure prophylaxis (PEP) recommendations. It was an observational, prospective, multicenter study set in Ile-de-France, France. METHODS: All children under 18 with a cancer diagnosis, currently or within 3months of receiving cancer treatment, regardless of varicella zoster virus (VZV) serostatus or previous personal history of varicella, were eligible. Study participants with significant exposure were reviewed prospectively for PEP indications. Main outcome measures were the percentage of exposure situations for which HCP were guideline-compliant, the proportion of available VZV serostatuses and the incidence of breakthrough varicella after different PEP approaches. RESULTS: A total of 51 patients from 15 centers were enrolled after 52 exposure episodes. Median age at exposure was 5 years (range, 1-15). Exposure within the household led to 38% of episodes. Prophylactic treatment consisted in specific anti-VZV immunoglobulins (V-ZIG) (n=19) or in oral aciclovir (n=15). No prophylactic treatment was given for 18 patients (in compliance, n=16). In compliance with guidelines, 17 patients received V-ZIG, 11 did not develop varicella (65%, [95% CI, 39-90%]); 15 received aciclovir, 13 did not develop varicella (87%, [95% CI, 67-100%]). Breakthrough varicella occurred in 11 patients, with simple clinical course in all cases; in 8/47 (17%) episodes when PEP was guideline-compliant versus 3/5 (60%) when not. DISCUSSION: Recommendations have been respected and are efficient. PEP needs to be standardized and a study carried out to define the optimal approach. Anti-VZV immunization of seronegative family members should be encouraged.

End-of-life care in children and adolescents with cancer: perspectives from a French pediatric oncology care network.

BACKGROUND: In developed countries, cancer remains the leading cause of pediatric death from illness after the neonatal period. OBJECTIVE: To describe the end-of-life care characteristics of children and adolescents with solid tumors (ST) or hematologic malignancies (HM) who died from tumor progression in the Île-de-France area. METHODS: This is a regional, multicentric, retrospective review of medical files of all children and adolescents with cancer who died over a 1-year period. Extensive data from the last 3 months of life were collected. RESULTS: A total of 99 eligible patients died at a median age of 9.8 years (range, 0.3-24 years). The most frequent terminal symptoms were pain (n = 86), fatigue (n = 84), dyspnea (n = 49), and anorexia (n = 41). Median number of medications per patient was 8 (range, 3-18). Patients required administration of opioids (n = 91), oxygen (n = 36), and/or sedation (n = 61). Decision for palliative care was present in all medical records and do-not-resuscitate orders in 90/99 cases. Symptom prevalence was comparable between children and adolescents with ST and HM. A wish regarding the place of death had been expressed for 64 patients and could be respected in 42 cases. Death occurred in hospital for 75 patients. CONCLUSIONS: This study represents a large and informative cohort illustrating current pediatric palliative care approaches in pediatric oncology. End-of-life remains an active period of care requiring coordination of multiple care teams.

PCA analgesia for children with chemotherapy-related mucositis: a double-blind randomized comparison of morphine and pethidine.

AIMS: This study aimed to compare pethidine and morphine on efficacy and toxicity in children with severe mucositis following chemotherapies. PATIENTS AND METHODS: From March 2000 to November 2003, 35 hospitalized children with chemotherapy-related mucositis were randomly assigned to receive double blindly "patient-controlled analgesia" (PCA) bolus doses of morphine or pethidine. The mucositis pain score was the mean of pain measured four times a day with a Visual Analogue Scale from day 2 to 5 of PCA. RESULTS: Study stops before total accrual for difficulties of recruitment. Out of the 29 patients with more than one day of PCA, the median (range) of the Mean Pain Score was 44 (13-72) and 33 (3-89) in the morphine (n = 14) and pethidine (n = 15) groups, respectively (P = 0.32). PCA was stopped for failure in 10 cases (five in each group). Constipation requiring specific treatment was higher in the morphine group (43% versus 0%). CONCLUSIONS: PCA with pethidine appears not inferior to morphine, with less constipation requiring specific treatment, but a larger study is warranted to confirm this.

Hepatic focal nodular hyperplasia in children previously treated for a solid tumor. Incidence, risk factors, and outcome.

BACKGROUND: The detection of hepatic nodules, particularly in patients treated for a previous malignancy, raises a diagnostic dilemma. Focal nodular hyperplasia (FNH) of the liver is an uncommon, benign tumor in children and must be differentiated from malignant hepatic lesions. The etiology of FNH is obscure, and its pathogenesis is poorly understood. FNH may be a reaction to localized vascular abnormalities and circulatory disturbances. The goal of the current study was to identify risk factors for the occurrence of FNH in children who had received prior treatment for a malignant tumor. METHODS: The current retrospective study examined 14 cases of FNH in pediatric patients who previously had been treated for a malignancy. Diagnosis was based on clinical and radiologic findings and was proven histologically in four cases. RESULTS: FNH lesions were discovered by chance during routine examination in 78% of patients. The incidence of FNH was particularly high in the current series (0.45%) compared with the incidence in the general pediatric population. High doses of alkylating agents (e.g., busulfan or melphalan), venoocclusive disease, and liver radiotherapy may be responsible for injury to the vascular endothelium and subsequent localized circulatory disturbances. FNH is characterized by the absence of complications after its detection; therefore, only close follow-up is recommended. CONCLUSIONS: FNH appears to be a late complication of an iatrogenic vascular disease in children with a history of malignancy.
