The Role of Delayed Imaging at MRI in Rare Non-enhancing Prostate Cancer Brain Metastases: A Case Report.

Brain metastases in prostate cancer are rare (<2% of cases). In magnetic resonance imaging, nearly all brain metastases exhibit contrast-enhancement, which may be affected by the time elapsed since the administration of the contrast agent. We discuss a case where the brain metastases in a patient with prostate cancer do not show a clear contrast-enhancement on magnetic resonance imaging using a standard brain metastases protocol.

The perivascular spaces in young and middle-aged stroke: A single-center analysis integrating clinical and Doppler ultrasound findings.

This research seeks to investigate correlations between enlarged Perivascular Spaces (PVSs) and clinical/imaging data, such as information obtained through Doppler analysis, in a population with young and middle-age stroke. We retrospectively reviewed demographics, clinical and MRI data, of 163 patients, with MRI confirmed stroke. All patients underwent ECD TSA (Eco-Color-Doppler of the Supra-aortic Trunks) and TCCD (Transcranial Eco-color-Doppler), to study extra or intracranial stenosis, presence and composition of plaques.

A possible role of e-FAST in the hemodynamically stable polytrauma patient: results of a single trauma center preliminary restrospective study.

Purpose: The purpose of this work is to evaluate whether EFAST can also play a role in the hemodynamically stable polytrauma patient, without delaying his arrival in the CT-scan room.

Methods: In a period of seven month, 748 polytrauma patients were retrospective valued; we analyzed the findings of the CT exams of 485 haemodynamically stable patients for whom the EFAST investigation was not requested, highlighting the possible presence of findings that, if reported during the EFAST, could have changed the patient management.

Results: 52 hemodynamically stable patients with CT examination findings potentially detectable by ultrasound examination directly in the shock room, which represent a percentage of about 11% of all the hemodynamically stable patients analyzed; about 54% of CT findings are represented by the presence of pneumothorax.

Comparison between Three Radiomics Models and Clinical Nomograms for Prediction of Lymph Node Involvement in PCa Patients Combining Clinical and Radiomic Features.

Purpose: We aim to compare the performance of three different radiomics models (logistic regression (LR), random forest (RF), and support vector machine (SVM)) and clinical nomograms (Briganti, MSKCC, Yale, and Roach) for predicting lymph node involvement (LNI) in prostate cancer (PCa) patients.

Visceral Adiposity and Its Impact on Nephrolithiasis: A Narrative Review.

Kidney stones represent a serious medical problem, resulting from several factors such as diet, genetics, and certain medical conditions. Visceral adipose tissue has been shown in recent research to play a significant role in kidney stone formation, making it a more precise indicator than traditional obesity indicators such as body mass index. The main aim of this review is to summarize studies on visceral obesity as a predictive marker for nephrolithiasis and to highlight new mechanistic pathways such as adipokine-mediated inflammation and its impact on kidney stone formation.
