    Abstract Ewing sarcoma is the second most common bone cancer in children, accounting for 2% of pediatric cancer diagnoses. Patients who present with metastatic disease at the time of diagnosis have a dismal prognosis, compared to the >70% 5-year survival of those with localized disease. Here, we utilized single cell RNA-sequencing to characterize the transcriptional landscape of primary Ewing sarcoma tumors and surrounding tumor microenvironment (TME). Copy-number analysis identified subclonal evolution within patients even prior to treatment. Primary tumor samples demonstrate a heterogenous transcriptional landscape with several conserved gene expression programs, including those composed of genes related to proliferation and EWS targets. We also were able to identify the composition of the TME and molecularly dissect the transcriptional profile of circulating tumor cells in peripheral blood at the time of diagnosis.

    Abstract Introduction: Hyperkalemia is common in medicine and requires rapid management. Besides the easily evoked causes such as renal failure, adrenal insufficiency, cell lysis or iatrogenic causes, false or pseudo-hyperkalemia should not be forgotten.
    Observations: Three patients (1 man, 2 women, aged 78, 84, 88) were managed for thrombocytosis (between 1306 and 2404 G/L) and non-symptomatic hyperkalemia (between 6.1 and 7.7mmol/L) are reported. Kalemia on blood collected in heparin tube was normal (4.4-4.6mmol/L). Therefore, no specific treatment for this pseudohyperkalemia was required.
    Conclusion: The combination of thrombocytosis and non-symptomatic hyperkalemia should suggest the diagnosis of pseudohyperkalemia and should prompt for a control of kalemia on blood collected in heparin tube. The recognition of this diagnosis is important in order to avoid unnecessary and potentially deleterious treatment of hyperkalemia.

    Abstract Background: Influenza-like illness (ILI) incidence estimates in individuals treated with immunosuppressants and/or biologics and/or corticosteroid for an autoimmune or chronic inflammatory disease are scarce. We compared the ILI incidence among immunocompromised population and the general population.
    Method: We conducted a prospective cohort study during the 2017-2018 seasonal influenza epidemic, on the GrippeNet.fr electronic platform, which allows the collection of epidemiological crowdsourced data on ILI, directly from the French general population. The immunocompromised population were adults treated with systemic corticosteroids, immunosuppressants, and/or biologics for an autoimmune or chronic inflammatory disease, recruited directly on GrippeNet.fr and also among patients of the departments of a single university hospital that were asked to incorporate GrippeNet.fr. The general population consisted of adults reporting none of the above treatments or diseases participating in GrippeNet.fr. The incidence of ILI was estimated on a weekly basis and compared between the immunocompromised population and the general population, during the seasonal influenza epidemic.
    Results: Among the 318 immunocompromised patients assessed for eligibility, 177 were included. During the 2017-2018 seasonal influenza epidemic period, immunocompromised population had 1.59 (95% CI: 1.13-2.20) higher odds to experience an ILI episode, compared to the general population (N = 5358). An influenza vaccination was reported by 58% of the immunocompromised population, compared to 41% of the general population (p < 0.001).
    Conclusion: During a seasonal influenza epidemic period, the incidence of influenza-like illness was higher in patients treated with immunosuppressants, biologics, and/or corticosteroids for an autoimmune or chronic inflammatory disease, compared to the general population.

    Abstract DICER1 syndrome is a rare hereditary cancer predisposition syndrome that has relevance to pediatric urology providers due to its association with many various pediatric genitourinary malignancies. We describe the case of a pediatric patient who was eventually diagnosed with a pathogenic DICER1 germline variant after undergoing resection of a cystic nephroma and pleuropulmonary blastoma.

    Title translation Cerebral infarction and tuberculosis: case report and literature review.
    Abstract Introduction: Although tuberculous meningitis is an uncommon presentation of tuberculosis, it still remains one of the deadliest forms of this disease. In this context, the occurrence of a cerebral infarct is an aggravating factor.
    Observation: A 48-year-old Asian man presented himself in the emergency room for dysarthria and dysphagia of progressive onset. Cerebral CT showed a recent ischemic defect of the right internal capsule. Lumbar puncture showed meningitis with low sugar levels. Pulmonary micronodules on the thoracic CT suggested tuberculosis, which was confirmed by a broncho-alveolar lavage. Anti-tuberculosis treatment and early corticosteroid resulted in an improvement of the patient's state.
    Conclusion: Cerebral infarctions in patients with tuberculous meningitis are events that cannot be underestimated in terms of frequency or severity. Their poor prognosis is partly the result of insufficiently defined management, which combines anti-tuberculosis treatment and early corticosteroid therapy.

    Abstract Background: COVID-19 is a major pandemic with potential cardiovascular complications. Few studies have focused on electrocardiogram (ECG) modifications in COVID-19 patients.
    Method and results: We reviewed from our database all patients referred to our hospital for COVID-19 between January 1st, 2020, and December 31st, 2020: 669 patients were included and 98 patients died from COVID-19 (14.6%). We systematically analyzed ECG at admission and during hospitalization if available. ECG was abnormal at admission in 478 patients (71.4%) and was more frequently abnormal in patients who did not survive (88.8 vs. 68.5%,
    Conclusion: The presence of abnormal ECG during COVID-19 is frequent. Physicians should be aware of the usefulness of ECG for risk stratification during COVID-19.

    Abstract Background: Following a study of predictors of superinfection in viral respiratory tract infections (VRTIs), this study analyzes the predictors of the outcome.
    Methods: Multicenter retrospective study conducted among adults who tested positive for VRTIs with reverse-transcription polymerase chain reaction. We compared characteristics between influenza virus, Paramyxoviridae, and Pneumoviridae and identified predictors of favorable short-term outcome, admission to the intensive care unit (ICU), and mortality.
    Results: A total of 590 patients had VRTI, including 347 (59%) influenza infections. Mean (SD) patient age was 71.0 (18.3) years, with a sex ratio of 0.91. In multivariate analyses, predictors of favorable short-term outcome were age ≤75 years (adjusted odds ratio [aOR] 5.38 [95% confidence interval, 1.59-18.2]), absence of respiratory disease (4.94 [1.01-24.37]), and absence of superinfection (aOR 3.91 [1.37-11.13]). The predictors of ICU admission were age ≤75 years (aOR 3.28 [1.71-6.25]), chronic respiratory disease (aOR 2.49 [1.20-5.19]), and procalcitonin level >0.25 ng/mL (aOR 4.25 [1.55-11.67]). Predictors of mortality were use of inhaled corticosteroids (2.49 [1.10-5.63]), influenza infection (2.73 [1.27-5.85]), Charlson score ≥5 (5.35 [1.90-15.05]), superinfection (2.54 [1.05-6.18]), and eosinophil count <50/µL (4.39 [1.19-16.2]). Certainty of superinfection was significantly associated with mortality (2.23 [1.15-4.3]).
    Conclusion: Our study revealed that superinfection was significantly related to the outcome, and that virus species affects mortality. These findings emphasize the need for improving the tools used in daily practice to confirm certainty of superinfection and for broader implementation of vaccination of individuals at risk of VRTIs.

    Abstract The incidence of central nervous system (CNS) involvement in patients with rhabdomyosarcoma (RMS) is low, and the outcome is dismal. We present a single institution analysis of CNS involvement of pediatric RMS. In 59 patients, the prevalence of CNS involvement was 11.9% (7 patients), higher than prior reports. Of the 6 deaths from disease, all had rapid progression, with a median survival of 14 days. The higher incidence could be secondary to treatment modifications or more sensitive detection. These findings are useful for decisions at the time of CNS involvement and could lead to modifications for future RMS clinical trials.

    Abstract Background: Viral respiratory tract infections (VRTIs) are among the most common diseases, but the risks of superinfection for different virus species have never been compared.
    Methods: Multicenter retrospective study conducted among adults who tested positive for VRTIs with reverse-transcription polymerase chain reaction. We compared characteristics between influenza (A or B) and paramyxoviruses (respiratory syncytial virus, parainfluenza virus types 1 and 3, and human metapneumovirus) and identified predictors of superinfection and hospitalization.s.
    Results: Five hundred ninety patients had VRTI, including 347 (59%) influenza and 243 paramyxovirus infections with comparable rates of superinfections (53% vs 60%). In multivariate analyses, the predictors of superinfections were age >75 years (adjusted odds ratio, 2.37 [95% confidence interval, 1.65-3.40]), chronic respiratory disease (1.79 [1.20-2.67]), and biological abnormalities, including neutrophil count >7000/µL (1.98 [1.34-2.91)], eosinophil count <50/µL (2.53 [1.61-3.98], and procalcitonin level >0.25ng/mL (2.8 [1.65-4.73]). The predictors of hospitalization were age >75 years old (adjusted odds ratio, 3.49 [95% confidence interval, 2.17-5.63]), paramyxovirus infection (2.28 [1.39-3.75]), long-term use of inhaled corticosteroids (2.49 [1.13-5.49]), and biological abnormalities, including neutrophil count >7000/µL (2.38 [1.37-4.12)] and procalcitonin level >0.25ng/mL (2.49 [1.23-5.02]). Kaplan-Meier survival curves showed that influenza-infected patients had a higher mortality rate than those with paramyxovirus infections (8.9% vs 4.5%, respectively; P = .02).
    Conclusions: Our study revealed a high rate of superinfection (56%), not related to viral species. However influenza virus was associated with a poorer prognosis than paramyxoviruses, pleading for a broader and large-scale vaccination of individual at risk of VRTIs.
