Article Synopsis
  • Hepatoblastomas show varied cell types that affect patient outcomes, but the reasons for this diversity are not well understood.
  • Researchers employed a single-cell analysis to explore the molecular factors contributing to these different cell states, revealing a spectrum of differentiation between liver cell types.
  • They discovered that specific genetic subclones within tumors exhibit unique levels of cellular flexibility, with certain subclones being more aggressive and responsive to chemotherapy due to the overexpression of specific genes.

CNS tumors with PLAGL1-fusion: beyond ZFTA and YAP1 in the genetic spectrum of supratentorial ependymomas.

Acta Neuropathol Commun

April 2024

Department of Neuropathology, GHU Paris-Psychiatrie Et Neurosciences, Sainte-Anne Hospital, 1, Rue Cabanis, 75014, Paris, France.

A novel methylation class, "neuroepithelial tumor, with PLAGL1 fusion" (NET-PLAGL1), has recently been described, based on epigenetic features, as a supratentorial pediatric brain tumor with recurrent histopathological features suggesting an ependymal differentiation. Because of the recent identification of this neoplastic entity, few histopathological, radiological and clinical data are available. Herein, we present a detailed series of nine cases of PLAGL1-fused supratentorial tumors, reclassified from a series of supratentorial ependymomas, non-ZFTA/non-YAP1 fusion-positive and subependymomas of the young.

Article Synopsis
  • About 5% of Wilms tumors involve vascular extension, requiring a complex surgical approach that influences management but not prognosis.
  • A study of 69 pediatric patients with Wilms tumors revealed significant findings, including a 37.5% rate of right atrial extension and complications like pulmonary embolism.
  • Despite challenges, the use of neoadjuvant chemotherapy led to a high overall survival rate of 89%, though postoperative renal insufficiency was identified as a risk factor for reduced survival.

Article Synopsis
  • Universal mask-wearing significantly reduces SARS-CoV-2 transmission, particularly in enclosed spaces and healthcare settings, but there are concerns about potential infection risks associated with eye exposure during medical procedures.* -
  • Evidence suggests that improper mask fit may cause airflow towards the eyes, leading to issues like dry eye, ocular inflammation, and a potential risk of intraocular infections.* -
  • While prolonged mask use can be linked to increased incidents of ocular problems, further research is needed to differentiate between effects caused by face masks and other factors impacting eye health during the COVID-19 pandemic.*

SUMMARYAlthough species and are uncommon causes of invasive fungal diseases (IFDs), these infections are associated with high mortality and are costly to treat with a limited armamentarium of antifungal drugs. In light of recent advances, including in the area of new antifungals, the present review provides a timely and updated overview of these IFDs, with a focus on the taxonomy, clinical epidemiology, pathogenesis and host immune response, disease manifestations, diagnosis, antifungal susceptibility, and treatment. An expansion of hosts at risk for these difficult-to-treat infections has emerged over the last two decades given the increased use of, and broader population treated with, immunomodulatory and targeted molecular agents as well as wider adoption of antifungal prophylaxis.

Service de Pneumologie et Allergologie Pédiatriques, AP-HP, Hôpital Universitaire Necker-Enfants Malades, Paris, France; Faculté de Médecine, Université Paris Descartes, Paris, France. Electronic address:

We report an unusual case of anaphylaxis induced by the lysozyme-containing over-the-counter-drug Lysopaine®, which contains 20 mg lysozyme hydrochloride and 1.5 mg cetylpyridinium chloride, in a 9-year-old child with allergy to hen's egg as well as multiple IgE-mediated food allergies. The involvement of lysozyme was confirmed by positive skin prick tests for Lysopaine® and the presence of specific IgE against lysozyme.

Parental involvement and adjustment during the diagnostic evaluation of autism spectrum disorder at two diagnostic centers.

Encephale

March 2024

Pôle de psychiatrie de l'enfant et de l'adolescent 93I05, EPS Ville-Evrard, 93330 Neuilly-sur-Marne, France.

Objectives: The primary objective of this study was to determine the effects of permanent, mediated parental presence during all autism spectrum disorder diagnostic evaluations on parental adjustment (perceived parental stress and sense of parental competence) compared with procedures that traditionally only involve parents in pivotal periods of the diagnosis. The level of satisfaction with the diagnostic procedure and parents' needs were also evaluated to complete this first objective. The secondary objective was to assess the effects of psychosocial, individual, and contextual variables on perceived parental stress and sense of parental competence.

Objectives: To identify infants with biliary atresia (BA), European Society of Paediatric Gastroenteroloy and Nutrition (ESPGHAN)/North American Society of Pediatric Gastroenteroloy and Nutrition (NASPGHAN) guidelines recommend measurement of conjugated/direct bilirubin in infants with prolonged jaundice and using a stool colour card (SCC). The 'Quality of Care' Task Force of ESPGHAN performed two surveys to assess current case finding for BA and age at Kasai portoenterostomy (KPE).

Methods: The first survey approached 26 European hepatology centres to report age at referral and age at KPE of all infants diagnosed with BA from 2015 to 2019.

Nuffield Department of Women's & Reproductive Health, University of Oxford, Oxford, United Kingdom; Oxford Maternal and Perinatal Health Institute, Green Templeton College, University of Oxford, Oxford, United Kingdom.

Article Synopsis
  • In early 2023, a study demonstrated that vaccinating pregnant women effectively reduces the chances of severe COVID-19 complications and maternal health issues.
  • The INTERCOVID-2022 study, conducted across 40 hospitals in 18 countries, analyzed how COVID-19 during pregnancy affects newborns and the benefits of maternal vaccination during the Omicron variant period.
  • Results showed that newborns from mothers who received a booster vaccine had significantly lower risks of contracting COVID-19 and experiencing preterm birth compared to those from unvaccinated mothers.

Centre de Référence Malformations Cardiaques Congénitales Complexes-M3C, Hôpital Universitaire Necker-Enfants Malades, Assistance Publique-Hôpitaux de Paris, Paris, France.

We report on a 6-year-old girl (18 kg/120 cm) who was diagnosed on day 6 postoperative with an occlusive thrombosis of a right ventricle-to-pulmonary artery conduit in the setting of a Ross procedure that was performed for severe native aortic valve insufficiency secondary to late diagnosis of bacterial endocarditis. We applied the Indigo® aspiration system from Penumbra® (Alameda, USA) to mechanically dissolve and remove the thrombus, restore flow, gradually wean from extracorporeal support, and replace the conduit after 4 days. The patient experiences good surgical outcomes at 3 months of follow-up.

Article Synopsis
  • HIV-associated cryptococcal meningitis is a major cause of AIDS deaths, prompting research to establish a faster method for detecting fungal load, which traditionally relies on CFU counts.
  • The study developed qPCR assays to identify and quantify different Cryptococcus species in cerebrospinal fluid from patients in sub-Saharan Africa, analyzing samples at various stages of antifungal treatment.
  • Results showed high sensitivity in detecting fungal load and identified a significant prevalence of Cryptococcus neoformans in both Botswana and Malawi, with some patients showing viable but non-culturable yeasts after treatment.

Article Synopsis
  • Liver transplantation is the primary treatment for end-stage liver disease, but there's limited information on the best imaging practices for monitoring children during the procedure.
  • A survey conducted by the European Society of Pediatric Radiology gathered feedback from 22 centers across 11 countries regarding their intraoperative imaging techniques.
  • Results showed that all centers use intraoperative ultrasound (US), mainly relying on color Doppler, but there's significant variation in how the ultrasound is conducted, including who operates the equipment and how often imaging is performed.
