Hemoadsorption for severe MIS-C in critically ill children, should we consider it as a therapeutic opportunity?

Multisystem inflammatory syndrome (MIS-C) is a new severe clinical condition that has emerged during the COVID-19 pandemic. MIS-C affects children and the young usually after a mild or asymptomatic COVID-19 infection. MIS-C has a high tropism for the cardiovascular system with need for inotropes and vasopressor support in 62% of cases.

Epidemiological characterization of SARS-CoV-2 variants in children over the four COVID-19 waves and correlation with clinical presentation.

Since the start of SARS-CoV-2 pandemic, children aged ≤ 12 years have always been defined as underrepresented in terms of SARS-CoV-2 infections' frequency and severity. By correlating SARS-CoV-2 transmission dynamics with clinical and virological features in 612 SARS-CoV-2 positive patients aged ≤ 12 years, we demonstrated a sizeable circulation of different SARS-CoV-2 lineages over the four pandemic waves in paediatric population, sustained by local transmission chains. Age < 5 years, highest viral load, gamma and delta clades positively influence this local transmission.

Challenging case of chronic Q fever endocarditis: usefulness of 18F-FDG PET/CT in the diagnosis and follow-up.

Diagnosis of infective endocarditis can be challenging for clinicians, especially when involving prosthetic valves. Recent data suggest that F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) could be a useful diagnostic tool in this setting. Here, we report a case of a patient with an aortic biological prosthesis who presented with a history of fever and fatigue.

Diffuse infantile hepatic hemangiomas in a patient with Beckwith-Wiedemann syndrome: A new association?

Beckwith-Wiedemann syndrome (BWS) is an overgrowth syndrome, caused by alterations in a cluster of imprinted genes located within the chromosome region 11p15.5. Common clinical features are overgrowth, macroglossia, lateralized overgrowth, abdominal wall defects, neonatal hypoglycemia and an increased risk of embryonal tumors, such as hepatoblastomas.
