Radiomics-Derived Data by Contrast Enhanced Magnetic Resonance in RAS Mutations Detection in Colorectal Liver Metastases.

: To assess the association of RAS mutation status and radiomics-derived data by Contrast Enhanced-Magnetic Resonance Imaging (CE-MRI) in liver metastases. : 76 patients (36 women and 40 men; 59 years of mean age and 36-80 years as range) were included in this retrospective study. Texture metrics and parameters based on lesion morphology were calculated.

Possible Association of Periodontal Disease and Macular Degeneration: A Case-Control Study.

Oral pathogens have been identified in bioptic specimens from Age-Related Macular Degeneration (ARMD) patients, and alveolar bone loss has been related to ARMD. Therefore, the possible association between ARMD and periodontal disease was investigated in the present case-control study, evaluating clinical and radiographic periodontal parameters, primarily, in cases vs. controls and, secondarily, in relation to ARMD risk factors, in cases, to highlight a possible pathogenic link between the disorders.

Benign Paroxysmal Positional Vertigo After Oral and Maxillofacial Surgery: Our Experience and Review of Literature.

Objectives: The aim of our study is to evaluate the influence of patient risk factors and the length of surgical time on the onset of BPPV (benign paroxysmal positional vertigo) and suggest surgical and clinical strategies to prevent this rare complication.

Method: Our retrospective study analyzes that, in 2 years, 281 patients, divided into three groups, underwent wisdom teeth extraction, sinus lift elevation and orthognathic surgery, at the Oral and Maxillofacial Department of the University of Naples "Federico II."

Results: Twenty-one patients presented postoperative BPPV.

Diastasis of rectus abdominis muscles: patterns of anatomical variation as demonstrated by ultrasound.

Purpose: The aim of our study was to categorise the anatomical variations of rectus abdominis muscle diastasis (diastasis recti) by using ultrasound (US).

Material And Methods: In a one-year period 92 women were evaluated with US because of suspected diastasis of rectus muscles. Patients were examined in a supine position, with head extended, upper limbs aligned to the trunk, and knees flexed.

A bump: what to do next? Ultrasound imaging of superficial soft-tissue palpable lesions.

Soft-tissue palpable lesions are common in clinical practice, and ultrasound (US) represents the first imaging option in the evaluation of a patient with a soft-tissue swelling. A full and systematic US assessment is necessary, however. This includes grayscale, color- and power-Doppler, spectral-Doppler, and possibly elastography facilities, as well as a trained operator.
