BACKGROUND AND AIMS: Intestinal ultrasound (IUS) is an accurate, patient-centered monitoring tool that objectively evaluates Crohn's disease (CD) activity. However, no current, widely accepted, reproducible activity index exists to facilitate consistent IUS identification of inflammatory activity. The aim of this study is to identify key parameters of CD inflammation on IUS, evaluate their reliability and develop an IUS index reflecting segmental activity. METHODS: There were 3 phases: 1) expert consensus Delphi method to derive measures of IUS activity; 2) an initial, multi-expert case acquisition and expert-interpretation of 20 blinded cases to measure inter-rater reliability for individual measures; 3) refinement of case acquisition and interpretation by 12 international experts, with 30 blinded case reads with reliability assessment and development of a segmental activity score...

BACKGROUND: In the absence of rapid on-side pathological evaluation, endoscopy staff generally "smears" endoscopic ultrasound guided fine needle aspiration (EUS-FNA) specimens on a glass slide. As this technique is vulnerable to preparation artifacts, we assessed if its quality could be improved through a smear-preparation-training for endoscopy staff. METHODS: In this prospective pilot study, 10 endosonographers and 12 endoscopy nurses from seven regional EUS-centers in the Netherlands were invited to participate in a EUS-FNA smear-preparation-training...

Carpal tunnel syndrome (CTS) is a peripheral neuropathy resulting from chronic median nerve compression. Chronic compression leads to neurological changes that are quantified through nerve conduction studies (NCS). Although NCS represent the gold standard in CTS assessment, they provide limited prognostic value. Several studies have identified ultrasound as a tool in diagnosing and potentially predicting the progression of CTS in patients. The purpose of this study was to evaluate the predictive value of ultrasound examination in CTS patients...

OBJECTIVE/HYPOTHESIS: Current literature has confirmed the benefits of sialendoscopy for the treatment of juvenile recurrent parotitis (JRP). However, this procedure is often performed unilaterally, although the disease can affect both sides. This article investigated the clinical course of the contralateral parotid (CL) gland in children requiring unilateral sialendoscopy with the goal of clarifying the necessity of primary bilateral sialendoscopy. STUDY DESIGN: Prospective cohort study in a tertiary center...

A 27-year-old man, previously diagnosed with IgA nephropathy, was referred for native kidney biopsy. After the procedure, the patient presented active bleeding revealed by Doppler and contrast-enhanced ultrasonography at the biopsy site. Successful embolization of the cortical fistula, the focus of bleeding, was achieved using ultrasound-guided thrombin injection and confirmed by Doppler ultrasonography, contrast-enhanced ultrasonography, and CT angiography. This case report shows that contrast-enhanced ultrasonography is useful for detecting active bleeding after a solid organ biopsy...

INTRODUCTION: Early-onset fetal growth restriction and small-for-gestational-age fetuses lead to an increased risk of adverse pregnancy outcomes. Doppler abnormalities can predict the occurrence of complications in the short-term, but normal fetal Doppler values at the time of diagnosis, do not exclude their occurrence in the long-term. The objective of this study was to investigate the capacity of a predictive model to assess individual risks for prenatal counseling at the time of diagnosis...

Ultrasound imaging is affected by coherent noise or speckle, which reduces contrast and overall image quality and degrades the diagnostic precision of the collected images. Elevational angular compounding (EAC) is an attractive means of addressing this limitation, since it reduces speckle noise while operating in real-time. However, current EAC implementations rely on mechanically rotating a one-dimensional (1D) transducer array or electronically beam steering of two-dimensional (2D) arrays to provide different elevational imaging angles, which increases the size and cost of the systems...

BACKGROUND: Emergency physicians are frequently required to identify and triage patients with increased intracranial pressure (ICP). Idiopathic intracranial hypertension (IIH) is a possible cause that must be considered. Its prognosis depends on prompt recognition and treatment, and progression of the disease can lead to permanent vision loss and considerable morbidity. Point-of-care ultrasound can rapidly identify elevated ICP. Measurements of the optic nerve sheath diameter (ONSD) and optic disc elevation (ODE) can act as surrogates for ICP...
