Multimodal ultrasound evaluation of asymptomatic ulnar nerve dislocation at the cubital tunnel.

Background: Ultrasonography has received broad acceptance as an effective peripheral nervous imaging examination. Shear wave elastography (SWE) can quantitatively assess the stiffness of nerves; however, little research has been conducted on elastography for ulnar nerve dislocation. The purpose of this study was thus to investigate the characteristics of multimodal ultrasound, including high-resolution ultrasonography and SWE, for asymptomatic ulnar nerve dislocation at cubital tunnel.

The role of ultrasonography in diagnosing acute closed volar plate injury of proximal interphalangeal joint.

Background: Acute closed volar plate injury of the proximal interphalangeal joint (PIP) is a common hand injury. In the past, there were few objective evaluation imaging methods for the degree of volar plate injury. The purpose of this study was to investigate the role of high frequency ultrasonography in diagnosing volar plate injury, and to explore whether ultrasound can provide a beneficial guidance to clinical decision-making and appropriate treatment adopting through accurate US classification of volar plate injury.

Associations of left renal vein entrapment with IgA nephropathy and Henoch-Schönlein purpura nephritis.

Objectives: The aims of the study were to identify whether left renal vein (LRV) entrapment was more prevalent in IgA nephropathy (IgAN) and Henoch-Schönlein purpura nephritis (HSPN) compared with other types of renal diseases, and the association of LRV entrapment with glomerular incidental IgA and galactose-deficient-IgA1 (Gd-IgA1) deposition.

Methods: A total of 797 patients with biopsy-proven kidney diseases have been screened for LRV entrapment by color Doppler ultrasound, and the prevalence of LRV entrapment in different types of renal diseases were then analyzed. Propensity score matching analysis was used to adjust for age, gender, and body mass index.

The role of ultrasonography in diagnosing hourglass-like fascicular constriction(s) of the anterior interosseous nerve.

Background: In the past, the diagnosis of hourglass-like fascicular constriction(s) of the anterior interosseous nerve mostly depended on electrophysiological examination, by which the location could not be diagnosed. There are few studies on the evaluation of hourglass-like fascicular constriction(s) by ultrasonography.

Purpose: To evaluate the role of ultrasonography in the diagnosis of hourglass-like fascicular constriction(s) of the anterior interosseous nerve.

The role of ultrasonography in the diagnosis of talocalcaneal coalitions.

Background: Patients with talocalcaneal coalitions (TCC) often undergo computed tomography (CT). However, ultrasonography diagnosis of TCC has been seldom done according to the literature.

Purpose: To investigate the accuracy of ultrasonography in diagnosing TCC compared to CT.

Diagnostic value of color Doppler sonography for spontaneous isolated superior mesenteric artery dissection.

The present study aimed to evaluate the clinical significance of color Doppler sonography (CDS) in the diagnosis of spontaneous isolated superior mesenteric artery dissection (SISMAD). The ultrasonographic images of 19 patients with SISMAD confirmed by computed tomography angiography (CTA) were retrospectively analyzed and the ultrasonographic features were summarized. The paired t-test was used to statistically analyze the differences in parameters determined by CTA vs.

Leptin promotes endothelial dysfunction in chronic kidney disease through AKT/GSK3β and β-catenin signals.

Endothelial dysfunction (ED) is a well-recognized instigator of cardiovascular diseases and develops in chronic kidney disease (CKD) with high rate. Recent studies have implicated that leptin is associated with endothelial dysfunction. We investigated the relationship between leptin and markers of ED in CKD patients and how leptin contributed to endothelial damage.
