Unusual Findings of Langerhans Cell Histocytosis in a Young Asymptomatic Patient: Case Report
Relaxation based Godunov type scheme for low mach multiphase flows
The present work is devoted to the numerical simulation of multiphase flows with two non-miscible compressible fluids. In this regime, interfaces can be tracked (Front tracking) or reconstructed (VOF, MOF). For theses approaches, interface topology changes and wave transmissions are difficult points. Diffuse interface methods are simple way to overcome these difficulties. In this paper we show how the usual techniques based on pressure relaxation can be adapted for this context. We also derive a elegant way to applied low mach preconditioning. For a simplified model, this approach recover previous work of Guillard and Murrone
L'antagonismo immanente. Da Tronti a Gramsci
Il presente saggio si pone il compito di tracciare una linea di continuità tra la produzione teorica di Mario Tronti e la scrittura carceraria di Antonio Gramsci in merito alla questione del rapporto, talvolta antinomico talaltra corrispondente, tra antagonismo e immanenza

A Comprehensive Geriatric Workup and Frailty Assessment in Older Patients with Severe Aortic Stenosis
Aortic stenosis (AS) represents a notable paradigm for cardiovascular (CV) and geriatric disorders owing to comorbidity. Transcatheter aortic valve replacement (TAVR) was initially considered a therapeutic strategy in elderly individuals deemed unsuitable for or at high risk of surgical valve replacement. The progressive improvement in TAVR technology has led to the need to refine older patients’ stratification, progressively incorporating the concept of frailty and other geriatric vulnerabilities. Recognizing the intricate nature of the aging process, reliance exclusively on chronological age for stratification resulted in an initial but inadequate tool to assess both CV and non-CV risks effectively. A comprehensive geriatric evaluation should be performed before TAVR procedures, taking into account both physical and cognitive capabilities and post-procedural outcomes through a multidisciplinary framework. This review adopts a multidisciplinary perspective to delve into the diagnosis and holistic management of AS in elderly populations in order to facilitate decision-making, thereby optimizing outcomes centered around patient well-being
The impact of COVID-19 pandemic on surgical neuro-oncology: A survey from the Italian society of neurosurgery (SINch)
Background: The COVID-19 pandemic and its impact on hospitals' activity and organization has imposed a vast change in standard neurosurgical oncology practice to accommodate for shifting resources. Aims: This investigation aims to analyse the nationwide capability in reorganizing the surgical neuro-oncological activity during the COVID-19 pandemic to evaluate whether COVID-19-pandemic influenced the surgical management in these patients. Method: A web-based dataset model organized by the Italian Neurosurgical Society (SINCh) was sent to all the Italian neurosurgical departments in May 2021, requesting to report the types and numbers of surgical procedures performed in the pre-pandemic period (from March 9th 2019 to March 9th 2020) compared to the pandemic period (from March 10th 2020 to March 10th 2021). Results: This multicentre investigation included the surgical activity of 35 Italian Neurosurgical Departments in a pre-pandemic year versus a pandemic year. During the COVID period, 699 fewer neuro-oncological patients were operated on than in the pre-COVID period. We noted a slight increase in urgency and a more severe decrease in elective and benign pathology. None of these differences was statistically significant. Surgically treated patients who tested positive for SARS-CoV-2 were 36, of which 11 died. Death was found to be COVID-related only in 2 cases. Conclusion: The reorganization of the Italian Neurosurgical Departments was able to guarantee a redistribution of the CNS tumors during the inter-pandemic periods, demonstrating that patients even in the pandemic era could be treated without compromising the efficacy and safety of the surgical procedure
