ABSTRACT
This study evaluated the epidemiological and clinical characteristics of human metapneumovirus (hMPV) infection among hospitalized patients with acute respiratory infections during 2015-2021 and assessed the impact of the coronavirus disease 2019 pandemic on hMPV infection. A single-center, retrospective cohort study was performed, including pediatric and adult patients with laboratory-confirmed hMPV. Of a total of 990 patients, 253 (25.6%), 105 (10.6%), 121 (12.2%), and 511 (51.6%) belonged to age groups 0-2, 3-17, 18-59, and ≥60 years, respectively. The highest percentage (23.0%) of patients were hospitalized during 2019 and the lowest (4.7%) during 2020. Patients < 18 years experienced high rates of comorbidities (immunodeficiencies: 14.4% and malignancies: 29.9%). Here, 37/39 (94.9%) of all bronchiolitis cases were diagnosed in patients < 2 years, whereas more patients in older age groups were diagnosed with pneumonia. A greater proportion of hMPV patients diagnosed with viral coinfection (mostly respiratory syncytial virus and adenovirus) were <18 years. The highest percentages of intensive care unit admissions were recorded among patients < 18 years. Our findings demonstrate that hMPV is an important cause of morbidity in young children and a possibly underestimated cause of morbidity among older adults.

INTRODUCTION: While survival rates among children with cancer are high, a significant proportion of the solid tumors are considered as hard to treat (HTT). Next generation sequencing (NGS) offers the ability to detect molecular changes in tumors. Its implementation may allow usage of targeted therapy for tumors that fail to respond to acceptable oncological treatment. Furthermore, these therapies are characterized by milder side effects than chemotherapy. NGS may also aid in establishing pathological diagnoses and occasionally, identifying cancer-predisposition syndromes. However, the benefit of NGS in the pediatric population is not clear. AIMS: Evaluating the benefit of NGS in children with 'HTT' Tumors. METHODS: A retrospective study of the usage of NGS in pediatric 'HTT' in the Department of Pediatric Hemato-Oncology at the Hadassah Medical Center. Patients' demographic and clinical characteristics, molecular changes in tumor, their influence on medical decisions and disease course - were all documented. RESULTS: Forty-seven NGS tests from 'HTT' tumors were completed between January 2018 to August 2020. The results of these tests dictated medical decisions in 18 cases (38.3%) while it proved utility in 10 cases (21.3%). Clinical response to targeted therapy, clarification of diagnosis and identification of germline changes were documented in 3 (6.4%), 4 (8.5%) and 3 (6.4%) cases, respectively. CONCLUSIONS: The usage of NGS may benefit children with 'HTT' and tumors with difficult diagnoses and in some cases may be life-saving. DISCUSSION: Cost-benefit considerations presumably prevent the assimilation of NGS tests in the standard care of pediatric oncology. It is possible that the current results will strengthen the more accurate usage of theses genomic techniques in children with 'HTT'.

Headache is a common complaint in children who present at the pediatric emergency department (PED). Serious conditions such as intracranial tumors and idiopathic intracranial hypertension (IIH) should be rapidly ruled out. Ophthalmoscopy for the presence of papilledema has long been considered critical to the assessment of headaches in children; however, the yield of this procedure is poorly validated. This retrospective study implemented a computerized search of the medical records of a single tertiary center to identify all children aged 2-18 years who presented at the PED complaining of headache between 2007 and 2017. The clinical, demographic, radiographic, and laboratory data were analyzed. Of the 948 children aged 2-18 years who presented at the PED complaining of headache, 536 had an ophthalmoscopy examination carried out by an ophthalmologist. Forty-one had papilledema, of whom 7 had an intracranial tumor, 15 had IIH, and 9 had optic nerve head drusen. Of the 495 children without papilledema, 3 had intracranial tumor, and 11 had IIH. The sensitivity and specificity of papilledema for the diagnosis of intracranial tumor were 70% and 93.5%, respectively, with an NPV and PPV of 99.4% and 17.1%, respectively. The sensitivity and specificity of papilledema for the diagnosis of intracranial pathology in general were 61.1% and 96.2%, respectively, with an NPV and PPV of 97.2% and 53.7%, respectively. Conclusion: Assessment by ophthalmoscopy for papilledema in children presenting to the PED with headache had high sensitivity and high specificity, thus reinforcing the importance of ophthalmoscopy as a screening tool in these children. What is Known: ⢠Headache is a common complaint in children. Serious intracranial pathologies need to be rapidly excluded. ⢠Ophthalmoscopy for the presence of papilledema is commonly used as a screening tool for intracranial pathology, but this procedure is poorly validated. What is New: ⢠Ophthalmoscopy for the assessment of papilledema in children who present with headache to the pediatric emergency department is shown to exhibit sensitivity and specificity for the diagnosis of intracranial pathology.

This retrospective study aims to describe the etiology and resistance patterns of pathogens causing bacteremia in children with solid tumors in a tertiary pediatric hematology-oncology center in Jerusalem, Israel (2011-2019). Factors associated with multidrug-resistant (MDR) bacteremia and mortality were analyzed. A total of 228 pathogens were isolated in 126 patients; 61.0% were gram-negative rods (GNR) and 38.2% were gram-positive cocci (GPC). The most common pathogens were Klebsiella pneumoniae (19.3%), Escherichia coli (17.5%), and coagulase-negative staphylococci (16.2%). The proportion of MDR-GNR was 18.2%, while the proportion of MDR-GPC was 55.2%. In logistic regression analysis, breakthrough bacteremia on a penicillin-group antibiotic (odds ratio [OR] 5.69, [95% confidence interval 1.42-22.76], p-value = 0.014) was associated and underlying diagnosis of neuroblastoma was inversely associated (OR 0.17, [0.04-0.81], p-value = 0.026) with MDR-GNR bacteremia; while the previous hospitalizations' duration (OR 1.032/day, [1.01-1.06], p-value = 0.007) and oncologic treatment intensity (OR 2.19, [1.08-4.45, p-value = 0.03) were associated with MDR-GPC bacteremia. Shock, prolonged profound neutropenia, and pediatric intensive care unit (PICU) admission were associated with 7-day mortality; and relapsed disease, oncologic treatment intensity, prolonged profound neutropenia, and PICU admission-with 30-day mortality in the univariate analyses. Empirical antibiotic choice should be based on factors associated with MDR infections in this specific population.

OBJECTIVES: To compare infection rates and circulating subtypes of human metapneumovirus (hMPV) before (2019-2020) and after the emergence of coronavirus disease 2019 (COVID-19) (2021) in Israel. METHODS: In total, 12,718 respiratory samples were collected from hospitalized patients of all ages during the years 2019 to 2021 at the Sheba Medical Center in Israel and subjected to reverse transcription-polymerase chain reaction analysis. In addition, whole-genome sequencing was performed to characterize the subtypes of hMPV circulating in Israel between 2019 and 2021. RESULTS: A total of 481 samples were found positive for hMPV. Before the emergence of COVID-19, hMPV peaked in winter months and declined thereafter. In sharp contrast, during the COVID-19 pandemic, we observed a delayed peak in hMPV infection cases and higher infection of young children. Viral sequencing showed a shift in the most prevalent circulating hMPV strain from A2b to B1 during the years 2019, 2020, and 2021. CONCLUSION: Compared with the years before the COVID-19 pandemic, in 2021, hMPV mostly affected young children, and the most prevalent circulating subtype shifted from A2b in 2019 to B1.

Targeted medications and immunotherapies are being developed to specifically target the pathways involved in tumours. There is limited experience with these new medications and their cutaneous side-effects in the paediatric population. A retrospective study of all paediatric oncological patients treated with targeted therapies and immunotherapies between 1 January 2013 and 1 August 2020 was carried out in 2 haemato-oncological referral centres. A total of 103 children were included in the study. The median (interquartile range) age was 13 years (8.4-16.9), male:female ratio 1.5:1, median (interquartile range) follow-up was 7 months (2-18). Fifty (48%) of the children developed cutaneous adverse events. Treatment was discontinued in only 3 (6%) cases and was altered in only (2%) 1 case due to a cutaneous adverse event. When targeted therapies and immunotherapies for tumours in children are used, there is an increased incidence of cutaneous adverse events. Nevertheless, treatment modification or discontinuation due to cutaneous side-effects is rarely needed.
