Intratesticular Vascular Architecture Seen by Ultrasound Microvascular Imaging (MicroV). Illustration of the Testis Vascular Anatomy.

The testis is a richly vascularized organ supplied by low-flow thin caliber vessels that are only partially detected by traditional Doppler systems, such as color and power Doppler. However, in the vascular representation, these techniques determine, albeit to different extents, a cut of the weak vessels due to the necessary application of wall filters that cut the disturbing frequencies responsible for artifacts generated by pulsations of the vascular walls and surrounding tissues. These filters cut a specific range of disturbing frequencies, regardless of whether they may be generated by low-flow vessels.

Fusion of magnetic resonance angiography and cisternography in acute ischemic stroke reveals the vessel anatomy ahead of the clot: a technical note to see beyond obstacles.

We describe how the fusion process between magnetic resonance angiography (MRA) and cisternography (MRC) promptly reveals vessel anatomy ahead of the clot, in patients affected by acute anterior circulation large vessel occlusion. This technique showed in 100% of subjects (n = 22) a clear tracing of vessel anatomy before and beyond the clot. The duration of the whole process is short and could be considered safe since no outcome differences have been found when compared with a control group (n = 23).

Exploring the evidence for the effectiveness of health interventions for COVID-19 targeting migrants: a systematic review protocol.

Introduction: Owing to their inherent vulnerabilities, the burden of COVID-19 and particularly of its control measures on migrants has been magnified. A thorough assessment of the value of the interventions for COVID-19 tailored to migrants is essential for improving their health outcomes as well as promoting an effective control of the pandemic. In this study, based on evidence from primary biomedical research, we aimed to systematically identify health interventions for COVID-19 targeting migrants and to assess and compare their effectiveness.

Safety and effect of Neuroform Atlas stent in the treatment of symptomatic intracranial stenosis: A single-center experience.

Background: Vascular intracranial stenosis (IS) is a significant cause of acute ischemic stroke (AIS). This single-center study aims to show that symptomatic IS treatment by using the Neuroform Atlas stent (Stryker neurovascular, Kalamazoo, MI, USA) could be effective in reducing vessel stenosis.

Methods: Ten patients affected by AIS or TIA, in the vascular territory of high-grade intracranial atherosclerotic lesions (>70% of vessel stenosis), older than 18-year-old, were treated by implanting a Neuroform Atlas stent (diameter of 4.

Microvascular imaging ultrasound (MicroV) and power Doppler vascularization analysis in a pediatric population with early scrotal pain onset.

Introduction: The power Doppler is a useful tool in the evaluation of pediatric acute scrotal pain. Nonetheless, it may have some inherent limitations in scrotal vascularization analysis, potentially causing unnecessary surgery. The microvascular imaging ultrasound (MicroV) is an innovative Doppler technique able to improve the detection of very low flow.

Non-invasive treatment of the sigmoid volvulus. A pediatric case report.

Sigmoid volvulus occurs when the sigmoid colic loop gets wrapped around its own mesocolon. While this condition is categorized as an extremely rare emergency in the pediatric population, diagnosis is often difficult due to the fact that its aspecific manifestations or sneaky symptoms are similar to other medical conditions. The available treatment options remain controversial up to this day, and the non-operative approach is more preferred in treating hemodynamic stable patients.

Imaging and Clinical Features of Neurocutaneous Melanosis in the Pediatric Population.

Background: Neurocutaneous Melanosis (NCM) is a rare nonfamilial phakomatosis characterized by the presence of congenital melanocytic nevi and abnormal melanocyte infiltration of the leptomeninges.

Objective And Methods: This paper shows the importance of early diagnosis and the most important imaging features of the disease on CT and MR scans. PubMed database was searched from January 1972 to September 2020.

Cerebellar amelanotic melanoma can mimic cerebellar abscess in a pediatric case of neurocutaneous melanosis.

Neurocutaneous melanosis (NCM) is a rare phakomatosis that may be associated with intracerebral masses. The differential diagnosis of intracerebral masses in NCM is often challenging and should include pigmented and nonpigmented lesions.

Negative effect of lockdown on juvenile idiopathic arthritis patients.

Introduction: The aim of this study is to evaluate a possible negative action of lockdown, during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, in the follow-up of juvenile idiopathic arthritis (JIA) patients.

Methods: We compared the number of JIA reactivations in the period March-July 2020 to the same months of 2018 and 2019.

Results: A total of 10 JIA reactivations have been documented on 58 patients (17%) visited in the period March-July 2018; 10 reactivations on 61 patients (16%) in the period March-July 2019; and 19 reactivations on 39 patients (49%) in the period March-July 2020, with a statistically significant increase (p <0.

Radiological evaluation of a case of chronic intestinal pseudo-obstruction (CIPO).

Chronic intestinal pseudo-obstruction (CIPO) is a severe form of gastrointestinal dysmotility (often due to derangement of the innervation and/or smooth muscle and/or interstitial cells of Cajal) with recurrent episodes of intestinal sub-occlusion. We describe a clinical setting and radiological features of CIPO in an 11-year-old girl with periodic relapses. Our attention was focused firstly on surgical causes, leading to a delay in the diagnosis; thus, is important detecting equivocal symptoms and considering the possible correlation to the CIPO for an early diagnosis and related prevention of acute episodes improving prognosis and quality of life of pediatric patients.

Acute scrotal pain in pediatric patients: diagnosis with an innovative Doppler technique (MicroV).

Acute scrotal pain is one of the most frequent symptoms in pediatric patients visited in the Emergency Department. Ultrasonography with color and power Doppler represents the first-line method that clinicians use to carry out the differential diagnosis between spermatic cord torsion and inflammation, but sensitivity and specificity are 63-100% and 97-100%, respectively; this variability may be related to operator's experience and testis vascular hemodynamics and also to machine performance and patient age. Recent technological innovations have made possible to create a new Doppler mode called ultrasound microvascular imaging.

Ongoing Computed Tomography Appraisal of Intestinal Perforation Due to an Ingested Foreign Body.

BACKGROUND Diagnosis and management of accidental or intentional ingestion of foreign bodies is a common problem at in emergency departments. This condition is generally observed in patients with limited consciousness or attention, such as children, elders, or psychiatric patients. Here, we report a case of intestinal perforation caused by ingestion of a foreign body that occurred during the performance of a contrast-enhanced CT scan.

Ultrasonography of traumatic injuries to limb peripheral nerves: technical aspects and spectrum of features.

Traumatic injury to limb peripheral nerves represents an important cause of morbidity and disability. Timely diagnosis and treatment are crucial to optimizing outcomes. The initial evaluation requires a careful history, a thorough physical examination, and electrodiagnostic tests, which lead in most cases to a diagnostic suspicion, but fail to provide an extensive qualitative and quantitative assessment of the nerve damage.

A Novel Diagnostic and Prognostic Tool for Simple Decompression of Ulnar Nerve in Cubital Tunnel Syndrome.

Background: Surgical decompression of the ulnar nerve (UN) is effective for treating cubital tunnel syndrome (CubTS). Nevertheless, the outcome is not always satisfying. Different surgical, clinical, and imaging findings have been claimed as outcome predictors, but there is no consensus in the literature.

Cross-sectional Imaging of Parotid Gland Nodules: A Brief Practical Guide.

Clinical evaluation and ultrasound examination are the first steps in the evaluation of a patient with a swelling of the parotid region. After the detection of a nodular lesion, cytological or histological confirmation is usually performed to achieve the diagnosis, while the choice of cross-sectional imaging (computed tomography scan and magnetic resonance imaging) may significantly vary from one physician to another, on the basis of the degree of confidence that both radiologist and surgeon have with this kind of imaging. This work focuses on some essential "reporting points" in cross-sectional imaging evaluation of parotid nodules, chiefly helpful to the radiologist when the ultrasonography assessment is considered incomplete and requires a further evaluation.

Extracellular vesicles: pathogenetic, diagnostic and therapeutic value in traumatic brain injury.

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide. Accurate classification according to injury-specific and patient-specific characteristics is critical to help informed clinical decision-making and to the pursuit of precision medicine in TBI. Reliable biomarker signatures for improved TBI diagnostics are required but still an unmet need.

Superior Mesenteric Artery Syndrome in Patients with Crohn's Disease: A Description of 2 Cases Studied with a Novel Magnetic Resonance Enterography (MRE) Procedure.

BACKGROUND Superior mesenteric artery syndrome is caused by vascular compression of the third portion of the duodenum between the aorta and the superior mesenteric artery. It may occur with acute or chronic symptomatology, such as vomiting or postprandial abdominal pain, and it is usually caused by a lack of mesenteric fat pad under conditions of severe weight loss. Crohn's disease can be one of them.

Trauma in elderly patients: a study of prevalence, comorbidities and gender differences.

Aim: Trauma, in geriatric patients, increases with age, and is a leading cause of disability and institutionalization, resulting in morbidity and mortality. The aim of our study was to analyse the prevalence of trauma, the related risk factors, mortality and sex differences in the prevalence in a geriatric population.

Patients And Method: We observed 4,554 patients (≥65 years) with home injuries or car accidents.

Thin laryngeal foreign bodies in infants: diagnostic potential of MDCT.

A laryngeal foreign body (FB) is a significant, life-threatening event in the paediatric population. Incomplete airways obstruction by a thin, laminar, radiolucent FB lodged in the glottis or supraglottis is a rare occurrence that may present with non-specific symptoms, absence of chest findings, and normal radiographic investigations, resulting in misdiagnosis, delay in diagnosis, or prolonged recovery. We report two cases of 10-month-old male infants, each with a thin radiolucent FB lodged between the vocal folds that was detected with low-dose multidetector computed tomography (MDCT) and thin-slice reconstruction.

Superinfection of a Dead Hepatic Echinococcal Cyst with a Cutaneous Fistulization.

Cystic echinococcosis (CE), also known as "hydatid disease" (HD), is a zoonotic infection caused by the larval stage of , which infects humans as intermediate hosts through the orofecal route. Carried by the intestinal venous blood, the embryos released by the eggs of the tapeworms can reach every organ, especially the liver, turning into a hydatid cyst. Usually asymptomatic, the cysts can be incidentally detected through radiological examinations performed for other reasons.

Imaging and Management of Incidental Renal Lesions.

The increased use of imaging modalities in the last years has led to a greater incidence in depicting abdominal incidental lesions. In particular, "incidentalomas" of the kidney are discovered in asymptomatic patients or patients who suffer from diseases not directly related to the kidneys. The aim of this paper is to provide the radiologist with a useful guide to recognize and classify the main incidental renal findings with the purpose of establishing the correct management.

Embolization of a Bronchial Artery Aneurysm in a Chronic Obstructive Pulmonary Disease (COPD) Patient with Non-Massive Hemoptysis.

Background: Bronchial artery aneurysm (BAA) is a rare condition with a reported prevalence of less than 1% of all selective bronchial arterial angiograms. Despite its low incidence, BAA represents a potential cause of hemoptysis.

Case Report: We describe the case of a 63-year-old man suffering from chronic obstructive pulmonary disease (COPD), who presented with non-massive hemoptysis.

The relationship between scores and outcomes for polytrauma patients in the emergency department. A case study.

Aim: Traumas are one of the most relevant pathological events in health care, because of clinical and prognostic relevance. Morbidity and mortality rates are strongly affected by the timely and correct approach to the patient (golden hour). The objective of this study was to investigate the possible influence of the diagnostic time and of the Injury Severity Score (ISS) on outcomes in trauma patients.

PRIMARY NOCTURNAL ENURESIS IN CHILDREN WITH ALLERGIC RHINITIS AND SEVERE ADENOTONSILLAR HYPERTROPHY: A SINGLE CENTER PILOT STUDY.

Nocturnal enuresis is defined as intermittent urinary incontinence during sleep that occurs at least twice a week for three consecutive months. There is no unifying etiology for nocturnal enuresis in the pediatric population and the disorder is likely to be multifactorial. We aimed to investigate the relationship between primary nocturnal enuresis, allergic rhinitis, and related complications in a paediatric case series from a single Center.
