Imaging features of solid renal masses

2017

The widespread use of abdominal imaging techniques has increased the detection of solid renal masses over the past years. Imaging plays a crucial role in the management and surveillance and in determining which lesions need treatment. The "classical angiomyolipoma" is the only benign solid renal mass that can be characterized with confidence by imaging through the detection of a fat-containing lesion without calcifications. There is a large overlap of imaging features between benign and malignant renal masses that often makes difficult a correct characterization of these lesions. In this review, we discuss the imaging features of the main solid renal masses that may suggest a likely benign …

Vertigo in childhood: A methodological approach

2012

Children complaints dizziness merit meticulous evaluation to differentially diagnose a vestibular disease. A syndrome mimicking certain classic signs and symptoms of adult vestibular disorders may be presents in children, such as benign paroxysmal positional vertigo, usually associated with aging. Benign paroxysmal vertigo, in which migraine is a manifestation, with sudden onset of dizziness is a rare peripheral vestibular disorder that is commonly ignored or misdiagnosed. This review covers the development of the diagnosis, evaluation and treatment approaches of vertigo of childhood, a valid support for physician that approach dizzy children (Ref. 25).

Liver Imaging Reporting and Data System (LI-RADS) v2018: diagnostic value of ancillary features favoring malignancy in hypervascular observations ≥ 1…

2020

This study was conducted in order to assess the diagnostic accuracy of LI-RADS v2018 ancillary features (AFs) favoring malignancy applied to LR-3 and LR-4 observations on gadoxetate-enhanced MRI. In this retrospective dual-institution study, we included consecutive patients at high risk for hepatocellular carcinoma (HCC) imaged with gadoxetate disodium-enhanced MRI between 2009 and 2014 fulfilling the following criteria: (i) at least one LR-3 or LR-4 observation ≥ 10 mm; (ii) nonrim arterial phase hyperenhancement; and (iii) confirmation of benignity or malignancy by pathology or imaging follow-up. We compared the distribution of AFs between HCCs and benign observations and the diagnostic p…

Characterization of Metabolically Healthy Obese People and Metabolically Unhealthy Normal-Weight People in a General Population Cohort of the ABCD St…

2017

There is actually no consensus about the possibility that in some instances, obesity may be a benign metabolically healthy (MH) condition as opposed to a normal-weight but metabolically unhealthy (MUH) state. The aim of this study was to characterize MH condition and to investigate possible associations with metabolic and cardiovascular complications. One thousand nineteen people (range of age 18–90 years) of the cohort of the ABCD_2 study were investigated. Participants were classified as normal weight (BMI < 24.9 kg/m2) or overweight-obese (BMI ≥25 kg/m2); they were also classified as MH in the presence of 0-1 among the following conditions: (a) prediabetes/type 2 diabetes, (b) hyperte…

Extracranial metastasizing solitary fibrous tumors (SFT) of meninges: Histopathological features of a case with long-term follow-up

2012

Extrapleural solitary fibrous tumors are uncommon mesenchymal neoplasms frequently observed in middle-aged adults and are classified, according to the WHO classification of soft tissue tumors, as part of the hemangiopericytoma tumor group. However, these two entities remain separated in the WHO classification of tumors of the central nervous system. In fact, meningeal solitary fibrous tumors are believed to be benign lesion and only in a minority of cases local relapses have been described, although detailed survival clinical studies on solitary fibrous tumors of meninges are rare. In contrast to hemangiopericytoma, which frequently shows distant extracranial metastases, such an event is ex…

Vertigo and osteoporosis: The correlation between nutritional intake of Vitamin D and incidence of recurring benign paroxysmal positional vertigo in …

2018

Introduction: Benign paroxysmal positional vertigo (BPPV) is the most common peripheral cause of vertigo. It can be defined as transient vertigo induced by rapid changes in head position associated with a characteristic paroxysmal positional nystagmus. The aim of this study is to evaluate the association between the serum calcium and Vitamin D levels in osteoporotic patients affected by recurrent BPPV. Materials and Methods: Calcium and 25-hydroxy-Vitamin D levels were evaluated in peripheral venous serum samples of 40 BPPV patients. Results: The reduction of serum Vitamin D levels is present in 16 of BPPV patients with recurrence. After nutritional intake of Vitamin D there was a decline o…

The Pyridyl Functional Groups Guide the Formation of Pd Nanoparticles Inside A Porous Poly(4-Vinyl-Pyridine)

2015

The reactivity of palladium acetate inside a poly(4-vinylpyridine-co-divinylbenzene) polymer is strongly influenced by the establishment of interaction between the Pd precursor and the pyridyl functional group in the polymer. Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and simultaneous X-ray absorption near edge structure (XANES) and small angle X-ray scattering (SAXS) techniques have been applied to monitor the reactivity of palladium acetate in the presence of H-2 and CO as a function of temperature. H-2 reduces palladium acetate to Pd nanoparticles and acetic acid. The pyridyl groups in the polymer play a vital role both in stabilizing the formed acetic acid, thu…

Laparoscopic excision of a benign peritoneal cystic mesothelioma

2009

Benign cystic peritoneal mesothelioma is a rare tumor and most commonly occurs in women in the reproductive age group. It is very rare in women of postmenopausal age. We present a rare case of a postmenopausal woman with benign peritoneal cystic mesothelioma removed at laparoscopy.
