Purpose: Echocolor Power Doppler with contrast medium forms a non-invasive vascular image; the purpose of the study is to evaluate the effectiveness in differentiating benign and malignant tumors in the soft tissues of the limbs.
Material And Method: Echocolor Power Doppler with contrast medium was used to study 80 patients with swelling in the soft tissues of the limbs: there were 54 benign lesions, 22 sarcomas, and 4 aggressive desmoid fibromatoses.
Results: Were identified 4 patterns of wash-in and wash-out curves that could be correlated to the histological diagnosis: type I was present in 85% of benign lesions, type III in 91% of malignant lesions and in 3.7% of the benign ones, type II in aggressive fibromatoses, anomalous type in 4 benign lesions and 2 sarcomas; the curve was absent in 2 benign lesions.
Conclusions: Power Doppler Echocolor with contrast medium can become a useful method to be associated with traditional imaging methods in the differential diagnosis of swelling of the soft tissues of the limbs.

Background: Congenital heart disease (CHD) is the most common fetal malformation, and it can result first in cardiac remodeling and dysfunction and later in cardiac failure and hydrops. A limited number of studies have evaluated cardiac function in fetuses affected by CHD. Functional parameters could potentially identify fetuses at risk of cardiac failure before its development.

A woman in her early 60s presented with multiple transient neurological symptoms over the course of 20 months, including transient loss of power to her right lower limb. Initial workup with CT brain scan, carotid dopplers and ECG revealed no abnormality; however, MRI of the brain suggested recent ischaemic events in separate cortical territories. Subsequent transoesophageal echocardiogram revealed a large mobile mass histologically confirmed to be an atrial myxoma.

Aims: This study evaluates whether multi-chamber myocardial deformation analysis using speckle tracking echocardiography (STE) can enhance validated current staging systems and improve risk stratification for patients with moderate-to-severe aortic stenosis (AS).
Methods And Results: We reanalyzed 2D, Doppler, and STE data obtained from two cohorts: derivation (654 patients, median age: 82 years; 51% men) and validation (237 patients, median age: 77 years; 55% men) with at least moderate AS (aortic valve area<1.5 cm2).
Maternal cell-free DNA in early pregnancy for preeclampsia screening: a systematic review.

Purpose: To quantify the separation between maternal blood cell-free (cf)DNA markers in preeclampsia and unaffected pregnancies and compare with existing markers. This approach has not been used in previous studies.
Methods: Comprehensive systematic literature search of PubMed to identify studies measuring total cfDNA, fetal cf(f)DNA or the fetal fraction (FF) in pregnant women.
Variations of renal Doppler indices during the initial 24-hour predict acute kidney injury in patients with sepsis: A single-center observational case-control clinical study.

Background And Objective: The aim of this retrospective observational case-control study was to examine the significance of different renal Doppler marker variations within the initial 24-hour period as potential predictors of Acute Kidney Injury (AKI) in patients with sepsis.
Methods: A total of 198 sepsis patients were enrolled and categorized into two groups: the AKI group (n = 136) and the non-AKI group (n = 62). Three renal Doppler indices, Renal Resistive Index (RRI), Power Doppler Ultrasound (PDU) score and Renal Venous Stasis Index (RVSI), were measured within 6h (T0) and at 24h (T1) after ICU admission.
