CT imaging findings of epiploic appendagitis: an unusual cause of abdominal pain

2019

AbstractEpiploic appendagitis is a rare cause of acute abdominal pain, determined by a benign self-limiting inflammation of the epiploic appendages. It may manifest with heterogeneous clinical presentations, mimicking other more severe entities responsible of acute abdominal pain, such as acute diverticulitis or appendicitis. Given its importance as clinical mimicker, imaging plays a crucial role to avoid inaccurate diagnosis that may lead to unnecessary hospitalization, antibiotic therapy, and surgery. CT represents the gold standard technique for the evaluation of patients with indeterminate acute abdominal pain. Imaging findings include the presence of an oval lesion with fat-attenuation…

Validity and reliability of a pictorial scale of physical self-concept in spanish children. [Validez y fiabilidad de la escala pictográfica de autoco…

2019

The pictorial scale of Physical Self-Concept in Children (P-PSC-C) is a relatively new instrument for investigating physical self-concept in childhood. The current study aims to examine the validity and reliability of the Spanish version of the P-PSC-C, and also to analyse the validity according to the children’s age. A sample of 365 primary school age (M = 9.21, SD = 1.92) students participated; divided in two groups, those aged 9 or younger and those 10-11 years old. Surveys were used to assess perceived physical concept individually. Confirmatory factor analysis (CFA) with diagonally weighted least square estimator specifically designed for ordinal data and a scaled test statistic was co…

The importance of strategic leadership in cyber security : Case of Finland

2019

Cyber security has become one of the biggest priorities for businesses and governments. Streamlining and strengthening strategic leadership are key aspects in making sure the cyber security vision is achieved. The strategic leadership of cyber security implies identifying and setting goals based on the protection of the digital operating environment. Furthermore, it implies coordinating actions and preparedness as well as managing extensive disruptions. The aim of this paper is to define what is strategic leadership of cyber security and how it is implemented as part of the comprehensive security model in Finland. The paper also asks (and answers) how the strategic leadership of cyber secur…

Some years ago Cheung et al. (2008) proposed the complete design (CD) for measuring the failure of selective attention in composite objects. Since the CD is a fully balanced design, analysis of response bias may reveal potential effects of the experimental manipulation, the stimulus material, and/or attributes of the observers. Here we used the CD to prove whether external features modulate perception of internal features with the context congruency paradigm (Nachson et al., 1995; Meinhardt-Injac et al., 2010) in a larger sample of N = 303 subjects. We found a large congruency effect (Cohen's d = 1.78), which was attenuated by face inversion (d = 1.32). The congruency relation also strongly…

Angst als Textspur und Bildspur in Graphic Novels zum historischen Geschehen des 20. Jahrhunderts

2020

Neben vielen anderen Charakterisierungen, etwa ‚Jahrhundert der Diktatoren‘, ist für das 20. Jahrhundert wahrscheinlich auch die Formulierung ‚Jahrhundert der Angst‘ gerechtfertigt. Dieser Beitrag ist ein erster Versuch, die Darstellung von Angst in verbal-piktoralen Narrativen zu erschließen. Text- und Bildspuren zu Angst – politisch genutzte Techniken der Angsterzeugung einerseits und bis zu dauerhafter Traumatisierung gehende Angsterfahrung andererseits – sind in vielen Graphic Novels zur Geschichte des 20. Jahrhunderts ein wesentliches Deutungsangebot. Obwohl ästhetisch und intellektuell anspruchsvoll, somit ein Angebot zur Aufarbeitung von Geschichte, ist diese Fokussierung von Angst d…

3D reconstruction techniques made easy: know-how and pictures

2005

Three-dimensional reconstructions represent a visual-based tool for illustrating the basis of three-dimensional post-processing such as interpolation, ray-casting, segmentation, percentage classification, gradient calculation, shading and illumination. The knowledge of the optimal scanning and reconstruction parameters facilitates the use of three-dimensional reconstruction techniques in clinical practise. The aim of this article is to explain the principles of multidimensional image processing in a pictorial way and the advantages and limitations of the different possibilities of 3D visualisation.

S-Detect characterization of focal breast lesions according to the US BI RADS lexicon: a pictorial essay

2020

High-resolution ultrasonography (US) is a valuable tool in breast imaging. Nevertheless, US is an operator-dependent technique: to overcome this issue, the American College of Radiology (ACR) has developed the breast imaging-reporting and data system (BI-RADS) US lexicon. Despite this effort, the variability in the assessment of focal breast lesions (FBLs) with the use of BI-RADS US lexicon is still an issue. Within this framework, evidence shows that computer-aided image analysis may be effective in improving the radiologist’s assessment of FBLs. In particular, S-Detect is a newly developed image-analytic computer program that provides assistance in morphologic analysis of FBLs seen on US …

Ipsilesional and contralesional regions participate in the improvement of poststroke aphasia: a transcranial direct current stimulation study

2015

In the past few years, noninvasive cerebral stimulations have been used to modulate language task performance in healthy and aphasic patients. In this study, a dual transcranial direct current stimulation (tDCS) on anterior and posterior language areas was applied for 2 weeks to a patient with a possible crossed aphasia following a right hemisphere stroke. Inhibitory cathodal stimulation of the right Brodmann areas (BA) 44/45 and simultaneous anodal stimulation of the left BA 44/45 improved the patient’s performance in picture naming. Conversely, the same bilateral montage on BA 39/40 did not produce any significant improvement; finally, electrode polarity inversion over BA 39/40 yielded a fu…
