Interobserver and intraobserver variability in the radiological assessment of sialolithiasis using cone beam computed tomography

2021

Background Data regarding the inter- and intraobserver variability in the radiological assessment of sialolithiasis using cone beam computed tomography are missing in the current literature. This study assessed the inter- and intraobserver variability in the radiological assessment of sialolithiasis using cone beam computed tomography (CBCT). Material and Methods In 107 patients, 130 salivary glands (65 parotid and 65 submandibular) with clinical signs of obstruction were assessed by four independent observers; 2 residents OMFS and 2 experienced OMFS. The observers analyzed the CBCT images and determined the absence or presence of one or more salivary stones in the affected gland. This proc…

Toponymic politics and the role of heritagisation in multiethnic cities in Romania

2022

Although scholars have made considerable progress in understanding the dynamics of heritagisation and toponymic politics, research is yet to explore how these may interact with each other. Drawing on a mixed-methods comparative qualitative study, this paper explores the politics of place naming and multilingualism in the context of heritagisation in three multiethnic cities in Romania: Târgu Mureş, Oradea and Baia Mare. We argue that the recent trends of heritagisation introduce a new element in the politics of place naming in ethnically diverse cities. Heritage becomes inclusive when it loses its importance in the power struggle between minority and majority political representatives. Once…

Perceivability of Map Information for Disaster Situations for People with Low Vision

2019

Digital maps have become increasingly popular in disaster situation to provide overview of information. However, these maps have also created barriers for many people, particularly people with visual impairments. Existing research on accessible maps such as tactile and acoustic maps focuses on providing solutions for blind persons to be able to perceive the information digital maps present. For people with low vision, who often rely on magnifier, good contrast and good navigation support, current digital map solutions present many challenges. In this paper we have studied two types of digital maps and their related surrounding text in the home page of disaster applications. The study focuse…

On the additivity of block designs

2016

We show that symmetric block designs $${\mathcal {D}}=({\mathcal {P}},{\mathcal {B}})$$D=(P,B) can be embedded in a suitable commutative group $${\mathfrak {G}}_{\mathcal {D}}$$GD in such a way that the sum of the elements in each block is zero, whereas the only Steiner triple systems with this property are the point-line designs of $${\mathrm {PG}}(d,2)$$PG(d,2) and $${\mathrm {AG}}(d,3)$$AG(d,3). In both cases, the blocks can be characterized as the only k-subsets of $$\mathcal {P}$$P whose elements sum to zero. It follows that the group of automorphisms of any such design $$\mathcal {D}$$D is the group of automorphisms of $${\mathfrak {G}}_\mathcal {D}$$GD that leave $$\mathcal {P}$$P in…

On 2-(n^2,2n,2n-1) designs with three intersection numbers

2007

The simple incidence structure $${\mathcal{D}(\mathcal{A},2)}$$ , formed by the points and the unordered pairs of distinct parallel lines of a finite affine plane $${\mathcal{A}=(\mathcal{P}, \mathcal{L})}$$ of order n > 4, is a 2 --- (n 2,2n,2n---1) design with intersection numbers 0,4,n. In this paper, we show that the converse is true, when n ? 5 is an odd integer.

Environmental Isocyanate-Induced Asthma: Morphologic and Pathogenetic Aspects of an Increasing Occupational Disease

2011

Occupational diseases affect more and more people every year. According to the International Labour Organization (ILO), in 2000 an estimated amount of at least 160 million people became ill as a result of occupational-related hazards or injuries. Globally, occupational deaths, diseases and injuries account for an estimated loss of 4% of the Gross Domestic Product. Important substances that are related to occupational diseases are isocyanates and their products. These substances, which are used in a lot of different industrial processes, are not only toxic and irritant, but also allergenic. Although the exposure to higher concentrations could be monitored and restricted by technical means, v…

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).

Der Schlaganfall als medizinischer Notfall

1999

Studies into the pathophysiology of acute ischaemic stroke have indicated that treatment options are likely to be optimised when early signs of stroke are recognised and treatment is initiated within 3 hours from symptom onset. For most patients there is a long delay between the onset of symptoms and the start of therapy. Many factors are responsible for this time delay: signs and symptoms often go unrecognised by patients, relatives and bystanders and stroke is not given a high priority by medical staff. Although a small number of stroke patients is treated as emergency and attended to by the emergency medical services within this time window, this number could easily be increased by inten…

Persistence of low back pain reporting among a cohort of employees in a metal corporation: A study with 5-, 10-, and 28-year follow-ups

2005

Low back pain (LBP) is a common symptom among adults but little is known about its persistence over time in defined populations. The aim of this study was to examine the persistence of LBP among a cohort of industrial employees studied in four successive surveys during a total of 28 years. Cross-tabulations and logistic regression was used to estimate the interdependence of LBP occurrence at the surveys. At baseline, 54% of the subjects reported local LBP and 25% LBP radiating to the lower limb(s). Persistent or recurrent LBP was common. Of those with LBP at baseline, 75, 73, and 88% reported it also at the 5-, 10- or 28-year follow-up, respectively. Of those with radiating pain, 66, 65, an…
