Is MRI imaging in pediatric age totally safe? A critical reprisal.

2017

Current radiological literature is strongly focussed on radiation imaging risks. Indeed, given there is a small but actual augment in cancer risk from exposure to ionizing radiation in children, it is important to understand what the risk of alternative techniques could be. We retrospectively review literature data concerning possible MR imaging risks, focussing on the biological effects of MR, sedation and gadolinium compound risks when dealing with infant patients. The main concerns can be summarized in: (1) Biological effects of non-ionizing electromagnetic fields (EMF) employed—whose mechanisms of interaction with human tissues are polarization, induced current, and thermal heating, res…

Crossing borders with social media: Online social networks and FDI

2017

Abstract Social media is embedded in today's internationalization strategy. Companies extend their reach into foreign countries by posting and tweeting. Firms also enhance their mobile capabilities in foreign markets (e.g., knowledge and reputation) through user-generated content in online social networks. Levering on the capabilities-based theory of the multinational enterprise, this paper builds upon a resource-based, industry/network-based, and institution-based view framework. The study provides a comprehensive conceptual and empirical model to explain the effect of social networks on foreign direct investment. Empirical analysis in a global panel dataset of >4500 multinational enterpri…

A regenerative 3D scaffold for inguinal hernia repair. MR imaging and histological cross evidence. Qualitative study

2021

Abstract Background Inguinal hernia is a degenerative disease occurring in a high motile surround. Stopping degeneration and promoting tissue regeneration should be the treatment goal. Groin hernias are conventionally managed with static flat meshes, mostly fixated to the delicate inguinal environment. Far from a regenerative effect, the biologic response of conventional hernia meshes is characterized by a foreign body reaction leading to a stiff/shrunken scar plate, which is often the source of unpleasant complications. Recently, a newly engineered 3D device for inguinal hernia repair – ProFlor-has been developed to produce a regenerative biological response. Unlike conventional hernia mes…

Plain film, CT and MRI sensibility in the evaluation of intraorbital foreign bodies in an in vitro model of the orbit and in pig eyes.

2000

Detection and characterization of intraorbital foreign bodies (IFB) is fundamental in acute trauma setting, preventing inflammatory sequelae or complications related to IFB movements when a MRI study is planned. Papers concerning plain film and CT sensibility in IFB detection show controversial results. For this reason we investigated plain film, CT and MRI sensibility in the evaluation of IFB. For an in vitro model, specimens of dry and fresh wood, glass, iron, plastic and graphite were immersed in animal lard and in a 0.9 % sodium chloride plus 3.5 g/dl human serum albumin solution. Specimens of different size and nature where also implanted into enucleated pig eyes. Air bubbles were intr…

Button batteries and typical swallowed foreign bodies can be differentiated in high-resolution X-Rays.

2021

Abstract Background Button battery ingestions have emerged as an increasing medical issue in recent years, especially for children. The frequent use of these energy sources in small appliances and toys is responsible for their ubiquitous occurrence in households. In addition to other possible foreign bodies, button batteries are particularly dangerous as they can cause severe complications in the aerodigestive tract. Objective The study aimed for a detailed analysis of specific radiographic identifiers of button batteries and similarly configured potential esophageal foreign bodies in high-resolution X-ray scans. Methods A selection of potentially hazardous button batteries - in cases of in…

Perkutane Entfernung von Schrittmachersonden

1989

The large number of pace-makers introduced transvenously has resulted in increasing the number of complications, amongst which infections and dislocations are prominent. It is usually necessary to remove the electrode, which can be attempted percutaneously by using a Dormia basket, a loop or forceps. Amongst the complications of this procedure are tears to the myocardium, with the risk of pericardial tamponade, or tears of the tricuspid valve leading to tricuspid insufficiency. Consequently, thoracic surgical intervention should be available if necessary. Four successful procedures are described.

Migration of a Fractured Acetabular Socket Wire Into the Femoral Vein: Indication for Urgent Removal by Venous Thrombectomy: A Case Report

1990

The migration of a foreign body into a great vein is a rare occurrence that requires urgent surgical intervention. In our patient one fragment of a circular acetabular socket wire marker had entered the femoral vein. Exact topographic location of the wire was achieved by computerized tomography. Urgent surgery revealed a floating wire within the venous lumen with associated thrombosis.

Management of Small Bowel Perforation by a Bizarre Foreign Body in a 55-Year-Old Woman

2018

Introduction. Ingestion of foreign bodies including dentures, fishbone, screw, and/or surgical devices can be a cause of morbidity, and it rarely could be fatal. Presentation of Case. We present the first hitherto reported case of mussel shell ingestion, which caused acute abdominal pain in a 55-year-old woman. The shell pierced ileal loops, and it was found in the abdominal cavity. Discussion. The accidental or voluntary ingestion of a foreign body is an uncommon event compared to the other causes of bowel perforation. It is fundamental to immediately remove the intestinal fluid, repair the tear, and prevent sepsis, because each delay in diagnosis can lead to a worst outcome. Conclusion. I…
