Association between Mortality and Lung Low Attenuation Areas in NSCLC Treated by Surgery.

Background: to test the association with overall survival (OS) of low attenuation areas (LAAs) quantified by staging computed tomography (CT) of patients who underwent radical surgery for nonsmall-cell lung cancer (NSCLC).

Methods: patients who underwent radical surgery for NSCLC at our institution between 1 January 2017 and 30 November 2021 were retrospectively evaluated. Patients who performed staging or follow-up CTs in other institutions, who received lung radiotherapy or chemotherapy, and who underwent previous lung surgery were excluded.

The relationship between radiation dose and bevacizumab-related imaging abnormality in patients with brain tumors: A voxel-wise normal tissue complication probability (NTCP) analysis.

Purpose: Bevacizumab-related imaging abnormality (BRIA), appearing as areas of restricted diffusion on magnetic resonance imaging (MRI) and representing atypical coagulative necrosis pathologically, has been observed in patients with brain tumors receiving radiotherapy and bevacizumab. We investigated the role of cumulative radiation dose in BRIA development in a voxel-wise analysis.

Methods: Patients (n = 18) with BRIA were identified.

Minimally Invasive Stent Screw-Assisted Internal Fixation Technique Corrects Kyphosis in Osteoporotic Vertebral Fractures with Severe Collapse: A Pilot "Vertebra Plana" Series.

Background And Purpose: Fractures with "vertebra plana" morphology are characterized by severe vertebral body collapse and segmental kyphosis; there is no established treatment standard for these fractures. Vertebroplasty and balloon kyphoplasty might represent an undertreatment, but surgical stabilization is challenging in an often elderly osteoporotic population. This study assessed the feasibility, clinical outcome, and radiologic outcome of the stent screw-assisted internal fixation technique using a percutaneous implant of vertebral body stents and cement-augmented pedicle screws in patients with non-neoplastic vertebra plana fractures.

Advanced stage empyemas in community-acquired pneumonia: how hospital re-organization during the Covid-19 pandemic affected the increase in surgically treated cases.

The cause of pleural empyema is bacterial pneumonia and three stages has been described in the evolution of this disease: exudative, fibrino-purulent and organizational phases. The first therapeutic intervention is the antibiotic therapy; where pharmacological therapy alone is not sufficient to eradicate the infection, it is also necessary a surgical treatment. Since the province of Piacenza having been in the epicenter area during the first Sars-Cov 2 pandemic wave in March 2020 and the number of patients with Covid-related pneumonia required invasive and non-invasive respiratory support, had a considerable organizational impact on pulmonology and respiratory unit, hindering an optimal treatment of the bacterial pneumonia both in community as well as in the hospital.
