[Cholesterol-lowering is not the Holy Grail, but neither is the work of the devil]

BAJNOK László

[Cholesterol-lowering statins are the most tested medications in respect of the effects and side-effects. Based on these, we can safely claim that most of the negative opinions about cholesterol-lowering are not realistic. It is not a panacea, but it is proven that around a 30% of cardio- and cerebrovascular risk reducation can be achieved by their regular taking, while the incidence of side effects and risks are at least one order of magnitude lower in each patient groups. For cholesterol, there is no “normal” lab threshold or low level, only “target values”, since the mean value in the general population is high in regard of atherosclerosis (the values measured at birth and among natural people can be considered normal). Let us appreciate the cholesterol- lowering medications because we do not have a large armamentarium!]

[BIOMECHANICS OF INTRACRANIAL ANEURYSMS]

FARKAS István, NYÁRY István, RAFFAI Gábor, ZILAHY G, MONOS Emil

[Introduction - Viscoelastic parameters of circumferential and meridional strips of ruptured and silent aneurysms were investigated (considered clinical and histological data either) in order to advance the prediction of risk of aneurysm rupture. Method - In our clinical practice, aneurysms managed by microsurgery aneurysm clipping were removed. Meridional and circumferential strips were cut. Strips were investigated by an uniaxial biomechanical instrument: distending force was recorded as the length of the strips was increased in steps. Normal stress-relaxation patterns were detected. The shape of strain curves well overlapped with the Standard Linear Solid Model curve, as had been expected. The viscosity, serial and parallel elastic moduli of the model were then computed. Results - Linear correlation was demonstrated amongst peek distending force detected and aneurysm strip thickness. Steric inhomogenity was detected at the meridional and circumferential strips. Strain-stress behaviour of ruptured and silent aneurysm specimen showed significant difference. Values of strips originated from patients suffered from hypertension as well as strips originated from aneurysms had been histologically found inflamed were higher. Discussion - Results of these observations are going to be used to set three dimensional computer model in cooperation with IT team of Budapest University of Technology and Economics to advance rupture risk prediction.]

[Job satisfaction and well-being among nurses]

NÉMETH Anikó, LAMPEK Kinga, BETLEHEM József

[Aim of the study: To monitor the changes in job satisfaction and well-being of nurses and to investigate whether the uncertainty caused by the reorganisation of workplaces affected their well-being. Sample and methods: Two cross-sectional studies were conducted in six Hungarian teaching hospitals in 2003 and in 2010 involving full time worker female inpatient care nurses who were asked to complete a questionnaire developed by the researchers. Results: The degree of acknowledgement and psychological strain at the workplace decreased significantly since the first survey. The autonomy at work dropped which is reflected by the diminished decision making and fewer opportunities to plan the working methods, work tasks, pace of work and jobs. Nurses evaluate the working community as worse, but the judgement of the head nurses did not change in 7 years. The rate of positive well-being significantly decreased since 2003, although the extent of negative well-being did not change. Conclusions: The job satisfaction of nurses decreased and the uncertainty at workplace affects their well-being.]

[Cervical space occupying lesions: diagnosis at sonoelastography]

UJLAKI Mátyás, MAGYAR Péter, KARLINGER Kinga

[Among cervical (neck) region tumours, the thyroid lesions and the metastatic lymph nodes are the most detectable with conventional B-mode ultrasonography (US). The use of MRI and CT scans are limited because of the cost, and in case of CT, the radiation. With the introduction and constant development of sonoelastography, we have in our hands a new imaging procedure which is cheap, fast and harmless, yet giving more information to the examiner than conventional US. The elastographic examination of thyroid lesions is a more explored area than the elastographic visualisation of cervical lymph nodes. The ‘off-line’ elastography showed the highest accuracy allowing to calculate and analyse the strain index of cervical lymph nodes - strain index > 1.5 (85% sensitivity, 98% specificity) - but the ‘off-line’ processing of US elastograms is still too time consuming to be used in busy clinical settings. During the examinations of the thyroid gland both real-time and off-line processed strain imaging were used. An Italian team made a great leap forward as they standardized the degree of distorsion under the application of the external force. Then using the Ueno and Itoh elasticity score they achieved remarkable accuracy with real-time sonoelastography (P <0.0001). On the other hand only those organs are suitable for the US elastography characterization which can be slightly compressed, consequently the examination of a lesion with calcified shell cannot give useful information. Near to the pulsating arteries substantial amounts of decorrelation noise may appear and the examiner has to pay attention what structures are in the ROI box since the sonoelastography method assumes computations relative to the average strain inside the box. To detect a follicular carcinoma in the thyroid gland remains a big challenge. Despite of the limitations most researchers agree on the fact that sonoelastography is a perfect tool to use in addition to the conventional US examination. B-mode US combined with sonoelastography raised the accuracy in differentiation in all cases. With this modality it is also possible to deduce the number of cases when healthy lymph nodes or tissue peaces are taken for biopsy during FNAB.]

[Migraine is a common health problem affecting women more commonly. It has been associated with an increased risk for cardiovascular events. In this study, we investigated whether aortic elastic properties is altered in migraineurs with low cardiovascular risk compared with healthy controls, in order to elicit further evidence on tentative association between migraine and increased risk of cardiovascular disease. Methods - Forty-three migraine patients with low CVD risk were enrolled to the study. Thirty-three volunteers, with a similar age and sex distribution served as a control group. Following parameters of the aortic elasticity were calculated: aortic strain, aortic stiffness (β) index and aortic distensibility. Results - Aortic strain was not statistically different between the study and control group. However, aortic distensibility and β index were significantly impaired in patients with migraine compared to control subjects Discussion - The elastic properties of the aorta in migreineurs may be different from normal by using easily available echocardiographic methods. This information may be a clue for clarification of cardiovascular system involvement in migraine.]
