Quantitative ultrasound fatty liver evaluation in a pediatric population: comparison with magnetic resonance imaging of liver proton density fat fraction.

Background: Biopsy remains the gold standard for the diagnosis of hepatic steatosis, the leading cause of pediatric chronic liver disease; however, its costs call for less invasive methods.

Objective: This study examined the diagnostic accuracy and reliability of quantitative ultrasound (QUS) for the assessment of liver fat content in a pediatric population, using magnetic resonance imaging proton density fat fraction (MRI-PDFF) as the reference standard.

Materials And Methods: We enrolled 36 patients.

Nonalcoholic fatty liver disease and diabetes.

Nonalcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease in the world and represents a clinical-histopathologic entity where the steatosis component may vary in degree and may or may not have fibrotic progression. The key concept of NAFLD pathogenesis is excessive triglyceride hepatic accumulation because of an imbalance between free fatty acid influx and efflux. Strong epidemiological, biochemical, and therapeutic evidence supports the premise that the primary pathophysiological derangement in most patients with NAFLD is insulin resistance; thus the association between diabetes and NAFLD is widely recognized in the literature.

US-Elastography With Different Techniques for Thyroid Nodule Characterization: Systematic Review and Meta-analysis.

Background: Thyroid nodules are frequent in adult population and thyroid cancer incidence has increased dramatically over the past three decades. The aim of this systematic review and meta-analysis was to evaluate the US-Elastosonography (USE) diagnostic performance in assessing the thyroid nodules malignancy risk.

Methods: PubMed and Embase databases were searched from January 2011 to July 2021.

Role of multiparametric ultrasound in testicular focal lesions and diffuse pathology evaluation, with particular regard to elastography: Review of literature.

Background: Ultrasound is the main requested technique for the assessment of traumatic, vascular, neoplastic, and inflammatory testicular pathology. Moreover, the role of ultrasound has broadened over the years along with the introduction of new techniques, such as contrast enhanced ultrasound and ultrasound elastography.

Objective: An updated representation of the pre-existing Literature evidence for multiparametric ultrasound imaging with particular regard to elastography, in the evaluation of focal and diffuse testicular pathologies, has been presented.

Multiparametric ultrasound evaluation of a case of bilateral carotid body tumor.

Paragangliomas are a rare form of highly vascularized tumors that originate from paraganglia Baysal (J Med Genet 39: 617-622, 2002). In the head and neck PGL arise primarily in four distinct areas: vagal, middle ear, and larynx and more frequently carotid bifurcation. Imaging evaluations include sonography, color Doppler, US-elastosonography and contrast-enhanced ultrasound (CEUS).

Narrative review of multiparametric ultrasound in parotid gland evaluation.

Disorders affecting parotid gland represent a heterogeneous group comprising congenital, inflammatory and neoplastic diseases which show a focal or diffuse pattern of appearance. The differentiation of neoplastic from non-neoplastic conditions of parotid glands is pivotal for the diagnostic imaging. Frequently there is evidence of overlapping between the clinical and the imaging appearance of the various pathologies.

Can strain US-elastography with strain ratio (SRE) improve the diagnostic accuracy in the assessment of breast lesions? Preliminary results.

Purpose: To assess the diagnostic value of strain ratio elastography (SRE), a semiquantitative elastosonographic method based on the displacement of the tissue from an external source (manual compression with the transducer), as compared and in combination with conventional ultrasound for the differentiation of breast lesions.

Methods: One hundred and eighty-two patients with breast lesions consecutively underwent B-mode, color Doppler US, and strain US-elastography. Each lesion was classified according to the BI-RADS lexicon by evaluating the size, the B-mode, and color Doppler features and then evaluated by SRE.

Evaluation of plantar fasciopathy shear wave elastography: a comparison between patients and healthy subjects.

Purpose: The aim of this study is to compare elasticity features between patients with plantar fasciitis (PFis) and an asymptomatic healthy control group using shear wave elastography (SWE) and to correlate SWE values with clinical scores.

Methods: Consecutive patients diagnosed with PFis and asymptomatic subjects were enrolled in the present study. Both groups underwent clinical, ultrasound (US), and SWE evaluation.

Natural History and Management of Familial Paraganglioma Syndrome Type 1: Long-Term Data from a Large Family.

Head and neck paragangliomas are the most common clinical features of familial paraganglioma syndrome type 1 caused by succinate dehydrogenase complex subunit D (SDHD) mutation. The clinical management of this syndrome is still unclear. In this study we propose a diagnostic algorithm for SDHD mutation carriers based on our family case series and literature review.

Jejunal multiple perforations for combined abdominal typhoid fever and miliary peritoneal tuberculosis.

Typhoid fever and tuberculosis, considered rare diseases in western countries, is still considered a notable problem of health issue in developing countries. The gastrointestinal manifestations of typhoid fever are the most common and the typhoid intestinal perforation (TIP) is considered the most dangerous complication. Abdominal localization of tuberculosis is the 6 most frequent site for extra pulmonary involvement, it can involve any part of the digestive system, including peritoneum, causing miliary peritoneal tuberculosis (MPT).
