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

Emerg Radiol 2020 Jun 26. Epub 2020 Jun 26.

Department of Biomedical and Dental Sciences and Morphofunctional Imaging, Division of Radiology, University of Messina, AOU Policlinico Universitario G. Martino, Via Consolare Valeria 1, 98100, Messina, Italy.

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. Read More

DWI/FLAIR Mismatch during Hyperacute Infarction of the Percheron Artery: Time Is Thalamus!

Case Rep Neurol 2020 Jan-Apr;12(1):127-130. Epub 2020 Mar 31.

School of Medicine and Surgery and Milan Center for Neuroscience (NeuroMI), University of Milano-Bicocca, Milano-Bicocca, Italy.

The artery of Percheron (AOP) is a single dominant thalamo-perforating artery that supplies bilaterally the medial thalami with variable contribution to the rostral midbrain. Occlusion of the AOP causes indeed variable and unspecific clinical symptoms due to this complex anatomy, and very often this diagnosis is delayed with the impossibility of recurring to intravenous thrombolysis (rTPA). Here, we report a case of AOP stroke that received a prompt diagnosis and therapy, owing to the availability of MR brain scan, showing a DWI/FLAIR mismatch typical of hyperacute infarctions.

Early repatriation post-thrombectomy: a model of care which maximises the capacity of a stroke network to treat patients with large vessel ischaemic stroke.

J Neurointerv Surg 2020 Apr 15. Epub 2020 Apr 15.

Interventional Neuroradiology Service, Department of Radiology, Beaumont Hospital, Dublin 9, Ireland.

Background And Purpose: Healthcare systems are challenged to provide access to thrombectomy in acute stroke patients. Either the "drip and ship" or "mothership" models result in increased numbers of patients in the endovascular stroke centre (ESC). We describe our approach for a "drip, ship, retrieve and leave" model repatriating patients immediately or within 24 hours of thrombectomy. Read More

Regulatory T Cells Modulate CD4 Proliferation after Severe Trauma via IL-10.

J Clin Med 2020 Apr 8;9(4). Epub 2020 Apr 8.

Experimental Radiology, Department of Radiology and Nuclear Medicine, Otto von Guericke University, 39120 Magdeburg, Germany.

Objective: Severely injured patients frequently develop an immunological imbalance following the traumatic insult, which might result in infectious complications evoked by a persisting immunosuppression. Regulatory T cells (Tregs) maintain the immune homeostasis by suppressing proinflammatory responses, however, their functionality after trauma is unclear. Here, we characterized the role of Tregs in regulating the proliferation of CD4 lymphocytes in traumatized patients (TP). Read More

Acute stroke management pathway during Coronavirus-19 pandemic.

Neurol Sci 2020 May 9;41(5):1003-1005. Epub 2020 Apr 9.

Neuroradiology Unit, Padua University Hospital, Padua, Italy.

Since the outbreak of the COVID-19 epidemic which in our region, Veneto (Italy), dates back to February, we were confronted with several challenges, but with a constant aim of keeping our Stroke Unit COVID-free. For this reason, in addition to creating a dedicated hot-spot as a pre-triage just outside the Emergency Department, together with the Neuroradiology Unit we obtained a mobile CT unit that could be used by COVID-positive or COVID-suspected patients. Furthermore, thanks to the collaboration with colleagues from different specialties (Infectious Disease, Internal Medicine, Intensive Care, Emergency Medicine), dedicated areas for COVID patients were activated.

Workflow patterns and potential for optimization in endovascular stroke treatment across the world: results from a multinational survey.

J Neurointerv Surg 2020 Apr 6. Epub 2020 Apr 6.

Diagnostic Imaging, University of Calgary Cumming School of Medicine, Calgary, Alberta, Canada

Background: The benefit of endovascular treatment (EVT) is highly time-dependent, and treatment delays reduce patients' chances to achieve a good outcome. In this survey-based study, we aimed to evaluate current in-hospital EVT workflow characteristics across different countries and hospital settings, and to quantify the time-savings that could be achieved by optimizing particular workflow steps.

Methods: In a multinational survey, neurointerventionalists were asked to provide specific information about EVT workflows in their current working environment. Read More
