RESUMEN

Aim: Children constitute an important and distinct subgroup of out-of-hospital cardiac arrest (OHCA) patients. This population-based cohort study aims to establish current age-specific population incidence, precipitating causes, circumstances, and outcome of paediatric OHCA, to guide a focused approach to prevention and intervention to improve outcomes. Methods: Data from the national Norwegian Cardiac Arrest Registry was extracted for the six-year period 2016-21 for persons aged <18 years. We present descriptive statistics for the population, resuscitation events, presumed causes, treatment, and outcomes, alongside age-specific incidence and total paediatric mortality rates. Results: Three hundred and eight children were included. The incidence of OHCA was 4.6 per 100 000 child-years and markedly higher in children <1 year at 20.9 child-years. Leading causes were choking, cardiac and respiratory disease, and sudden infant death syndrome. Overall, 21% survived to 30 days and 18% to one year. Conclusion: A registry-based approach enabled this study to delineate the characteristics and trajectories of OHCA events in a national cohort of children. Precipitating causes of paediatric OHCA are diverse compared to adults. Infants aged <1 year are at particularly high risk. Mortality is high, albeit lower than for adults in Norway. A rational community approach to prevention and treatment may focus on general infant care, immediate first aid by caretakers, and identification of vulnerable children by primary health providers. Cardiac arrest registries are a key source of knowledge essential for quality improvement and research into cardiac arrest in childhood.

RESUMEN

AIM: This work provides an epidemiological overview of out-of-hospital cardiac arrest (OHCA) in children in Germany between 2007 and 2021. We wanted to identify modifiable factors associated with survival. METHODS: Data from the German Resuscitation Registry (GRR) were used, and we included patients registered between 1st January 2007 and 31st December 2021. We included children aged between > 7 days and 17 years, where cardiopulmonary resuscitation (CPR) was started, and treatment was continued by emergency medical services (EMS). Incidences and descriptive analyses are presented for the overall cohort and each age group. Multivariate binary logistic regression was performed on the whole cohort to determine the influence of (1) CPR with/without ventilation started by bystander, (2) OHCA witnessed status and (3) night-time on the outcome hospital admission with return of spontaneous circulation (ROSC). RESULTS: OHCA in children aged < 1 year had the highest incidence of the same age group, with 23.42 per 100 000. Overall, hypoxia was the leading presumed cause of OHCA, whereas trauma and drowning accounted for a high proportion in children aged > 1 year. Bystander-witnessed OHCA and bystander CPR rate were highest in children aged 1-4 years, with 43.9% and 62.3%, respectively. In reference to EMS-started CPR, bystander CPR with ventilation were associated with an increased odds ratio for ROSC at hospital admission after adjusting for age, sex, year of OHCA and location of OHCA. CONCLUSION: This study provides an epidemiological overview of OHCA in children in Germany and identifies bystander CPR with ventilation as one primary factor for survival.

RESUMEN

Primary effusion lymphomas (PEL) are associated with human herpesvirus-8 (HHV-8) and usually occur in immunocompromised individuals. However, there are numerous reports of HHV-8-unrelated PEL-like lymphomas with unknown aetiology. Here we characterize an HHV-8-unrelated PEL-like lymphoma in an elderly woman who was negative for human immunodeficiency viruses 1 and 2, and hepatitis B and C. The woman was, however, a carrier of an inherited-chromosomally-integrated human herpesvirus-6A (iciHHV-6A) genome in one 19q telomere. The iciHHV-6A genome was complete in blood DNA, encoding a full set of protein-coding genes. Interestingly, the entire iciHHV-6A genome was absent from the HHV-8-unrelated-PEL-like lymphoma cells despite retention of both copies of chromosome 19. The somatic loss of the 19q-iciHHV-6A genome occurred very early during lymphoma development and we propose it occurred via telomere-loop formation and excision to release a circular viral genome that was subsequently lost. Whether release of the HHV-6A genome from the telomere contributed to lymphomagenesis, or was coincidental, remains unclear but this event may have deregulated the expression of HHV-6A or 19q genes or else disrupted telomere function. To establish the frequency and importance of iciHHV-6 loss from telomeres, the HHV-6 copy number should be assessed in tumours that arise in iciHHV-6 carriers.

RESUMEN

OBJECTIVE: To update the demographic data, treatment details and outcomes for GTN patients with brain metastases managed with the modern treatment protocols at the UK centre for gestational trophoblast neoplasia at Charing Cross Hospital in London. METHODS: The hospital database and pharmacy records were reviewed to identify GTN patients treated with brain metastases. Data was assembled on the specific GTN diagnosis, staging, prognostic scores, chemotherapy regimens, additional interventions and outcomes. RESULTS: During the 22 year study period, 27 GTN patients with brain metastases were treated. One case clearly resulted from a prior molar pregnancy, 3 were of uncertain aetiology and 23 cases had no prior molar pregnancy. The standard chemotherapy regimens were EMA-CO or EMA-EP given with an enhanced CNS methotrexate dose combined with intrathecal methotrexate. Five patients required emergency neurosurgery and routine radiotherapy was not employed. Twenty three (85%) patients are long term survivors and four patients died. Of the patients who died, all four had chemotherapy refractive disease and two had extended intervals of 18 and 30 years from their antecedent pregnancy. CONCLUSION: The incidence of brain metastases in postmolar pregnancy GTN is extremely low. Patients with non-molar choriocarcinoma have an approximate 20% risk of CNS disease and should have routine CNS imaging. Treatment with CNS doses of EMA-CO or EMA-EP appears curative for most patients.
