SÁGI Balázs, KÉSŐI István, VAS Tibor, CSIKY Botond, KOVÁCS Tibor, NAGY Judit

[Background: Arterial stiffness has a prognostic role in chronic cardiovascular diseases. Pulse wave velocity (PWV) determined by the carotid-femoral pulse detection is accepted as a gold standard method. Further diagnostic procedures are in use to assess the arterial stiffness including the finger photoplethysmography. The prognostic role of this method is limited in chronic renal diseases. The goal of our investigation was to determine the prognostic significance of the stiffness index (SIDVP) measured by the photoplethysmographic method in IgA nephropathy. Patients and methods: One hundred and three histologically proved IgA nephropathy patients with chronic kidney disease stage 1-4 were investigated (67 male, 36 female, 45 ± 11 years) and followed for an average 65 (6-107) months. The stiffness index was determined by the volume alteration of the digital artery during the cardiac cycle (Pulse Trace system, Micro Medical, Gilingham, Kent, UK). The primary combined end point was total mortality, major cardiovascular events (stroke, myocardial infarction or cardiovascular procedure, for example revascularisation) plus achieving end stage renal disease. The secondary end points were cardiovascular and renal end points alone. Results: The patients with increased stiffness index (> 10 m/s) had significantly more combined primary end point events (10/60 vs. 19/43, P = 0.015). In case of the secondary end points the renal end points were significantly more frequent in patients with higher stiffness index. Stiffness index has also proved to be an independent predictor on survival from other cardiovascular risk factors (age, hypertension, diabetes, obesity, lipid disturbances and decrease of renal function) using the Cox regression model in IgA nephropathy. Every 1 m/s increase in stiffness index resulted a 17% gain in the occurrence of the combined primary end point. Conclusions: Stiffness index determined by finger photoplethysmography is an eligible parameter to assess the prognosis in IgA nephropathy. Increased stiffness index in IgA nephropathy seems to be a good prognostic tool for identification of higher risk patients.]

MOLNÁR István, DEÁK Botond Zsolt, HEGYI Gabriella, KOVÁCS Zoltán, KAPÓCS Gábor, SZŐKE Henrik

[Objectives - Our aim was to evaluate the effects of percutaneous neurolysis of lumbal sympathetic ganglions on pain and the resulting changes in quality of life with validated objective and subjective methods. To follow the adverse effects and complications of the procedure. Materials and methods - A prospective, non-randomized, interventional, clinical cohort study under real life conditons was conducted. The time of the observation was 6 months. Palliative neural therapy was performed to reduce the ischemic pain of the affected leg of the patients involved in the study. Prior to treatment and after 35 days, Visual Analogue Scale (VAS) was used to measure the intensity of lower limb pain. The related changes in the quality of life were followed by a general 36-Item Short-Form Health Survey (SF-36) questionnaire. We measured the changes of the patients’ skin temperature and ankle/arm index. The post-treatment results were compared to the pre-treatment results. We compared the results of objective and subjective measures. We followed the side effects and complications of the pain therapy. Each of the examined subjects had obliterative (Fontaine II/b stage) arterial disease of the lower limbs, in which no revascularization intervention was feasible and their ischemic pain was of VAS≥7. Results - Data of 124 patients (69 male, 55 female) could be evaluated. The decrease in intensity of limb pain in the post-treatment period was significant (p=0.001). Quality of life also indicated a significant improvement (p=0.004). Changes in skin temperature and ankle/arm index demonstrated significant improvement (p≤0.005): skin temperature increased from 27.6°C to 31.2°C, the ankle/arm index inceased from 0.67 to 0.83 on average. Changes in objective and subjective measures correlated with each other. No worthening of symptoms, serious adverse events or complications were observed. Conclusion - The chemical denervation of the lumbar sympathetic ganglions with percutaneous application is a minimally invasive intervention, useful in outpatient care, which can be well tolerated by the patient without any significant side effect or complication. Its hyperaemic effect and the pain reduction of the leg can improve the quality of life of the patients.]

[The importance of recognition and proper treatment of hypertension and the maintenance of adherence in hypertension care]

NEMCSIK János, PÁLL Dénes, JÁRAI Zoltán

[Hypertension is the leading cause of death and disability-adjusted life years. In the United States hypertension accounts for more cardiovascular (CV) deaths than any other modifiable CV disease risk factor and was second only to cigarette smoking as a preventable cause of death for any reason. In our country the situation is similar. In Hungary the number of subjects with hypertension is approximately 3.5 million and this high prevalence contributes markedly to the poor Hungarian CV morbidity and mortality figures. The recognition of hypertension, the initiation of drug therapy and the long-term follow- up of the patients is mainly the task of primary care. Besides that it inheres high responsibility, this is also a grateful commitment, as hypertension in most of the cases can be treated properly with lifestyle-changes and medications leading to a marked decrease of CV complications, especially stroke. In our review article we would like to focus on the high prevalence of hypertension worldwide as well as in our country, the exact implementation of screening, the risk reduction potential of the proper treatment and the importance of the long-term maintenance of treatment adherence.]

[Hypertension and atrial fibrillation. Part 1. - Epidemiological data. The pathomechanism of PF in hypertension]

KÉKES Ede

[Atrial fibrillation (PF) is the most common arrhythmia on the basis of analyzes conducted in different regions of the world. The main reason for this is the aging of the population. High blood pressure is one of the major factors of mortality in both developed and poor economical countries. The combined presence of the two diseases presents many hazards to our body. The most significant of these is the development of thromboembolic stroke, which is constantly increasing with age. The author analyzes in detail the aetiology called atrial cardiomyopathy, behind which there are complex structural, architectural, contractile and electro-physiological changes and leads to clinical manifestation of PF.]

A rare condition mimicking stroke: Diabetic uremic encephalopathy

TEKESIN Aysel, ERDAL Yuksel, MAHMUTOGLU Soydan Abdullah, HAKYEMEZ Ahmet, EMRE Ufuk

Uremic encephalopathy (UE) is a metabolic disorder associated with acute or chronic renal failure. It is characterized by the acute or subacute onset of reversible neurological symptoms and specific imaging findings. It is uncommon for uremic encephalopathy to be associated with acute bilateral lesions of the basal ganglia in diabetic uremic patients, and this can be seen most often in Asian patients. Here, we report a patient with diabetic uremic encephalopathy and bilateral basal ganglia lesions who developed acute onset dysarthria. The clinical and magnetic resonance brain imaging findings resolved after hemodialysis treatment.

[Strategies of using the new antiepileptic drugs for epilepsy in adults]

NIKL János

[The new antiepileptic drugs have not changed the basic pharmacological treatment principles of epilepsy, but they have given greater choice in focal and in generalized epilepsies as well. The new drugs are not necessarily more effective than traditional drugs, but they have favourable pharmacokinetic characteristics, fewer interactions and better adverse effect profile in the acute and chronic phase of the treatment. They generally show a lower teratogenicity risk than the standard antiepileptics, although carbamazepine, one of the standard drugs can be used and zonisamide, a new one must be avoid in pregnancy. Due to characteristics mentioned above they are not only effective as add-on therapy, but in monotherapy as well. On the basis of the international and national recommendation lamotrigine and levetiracetam belong to the first line antiepileptics. The favourable tolerability of the new antiepileptics may improve the patient’s compliance and adherence to the given treatment. The low teratogenicity makes them especially suitable for the treatment of women of childbearing age. The new antiepileptic drugs can succesfully used for the treatment of special patients’ groups as for the post stroke, poszttraumatic epilepsies, for the epilepsies accompanied with brain tumours as well as for epilepsies in the elderly. The new drugs are advantageous for the treatment of such patients who have psychiatric symptoms or signs of cognitive decline and high risk of these symptoms respectively.]

Novel structured MRI reporting system in neonatal hypoxic-ischemic encephalopathy - issues of development and first use experiences

LAKATOS Andrea, KOLOSSVÁRY Márton, SZABÓ Miklós, JERMENDY Ágnes, BAGYURA Zsolt, BARSI Péter, RUDAS Gábor, KOZÁK R. Lajos

Purpose - To develop an evidence-based, standardized structured reporting (SR) method for brain MRI examinations in neonatal hypoxic-ischemic encephalopathy (HIE) suitable both for clinical and research use. Materials and methods - SR template development was based on comprehensive review of the pertinent literature with the basic sections and subdivisions of the template defined according to MRI sequences (both conventional and diffusion-weighted, MR-spectroscopy (MRS), and T2*-weighted imaging), and the items targeted on age-related imaging patterns of HIE. In order to evaluate the usability of the proposed SR template we compared data obtained from the brain MR image analysis of 87 term and 19 preterm neonates with the literature. The enrolled 106 infants were born between 2013 and 2015, went through therapeutic hypothermia according to the TOBY criteria due to moderate to severe asphyxia and had at least one brain MRI examination within the first two weeks of life. Ethical approval was obtained for this retrospective study. Descriptive statistical analysis was also performed on data exported from the structured reporting system as feasibility test. Results - The mean gestational age of the study population was 38.3±2.2 weeks; brain MRI was performed on 5.8±2.9 day of life, hence in 78% of our patients after the conclusion of therapeutic hypothermia. Our main imaging findings were concordant to the pertinent literature. Moreover, we identified a characteristic temporal evolution of diffusion changes. Interestingly 18% (n=19/106) of the clinically asphyxiated infants had isolated axial-extraaxial haemorrhage without any imaging sign of HIE. Conclusion - In this article our approach of reporting HIE cases with our novel SR template is described. The SR template was found suitable for reporting HIE cases, moreover it uncovered time and location dependent evolution of diffusion abnormalities (and pseudonormalization, as well), suggesting its usefulness in clinical research applications. The high number of isolated intracranial haemorrhages, and the changing diffusion pattern emphasizes the importance of early imaging in HIE.

Can high uric acid levels be an independent risk factor for acute ischemic stroke due to large-artery atherosclerosis?

ACAR Türkan, ARAS Guzey Yesim, GÜL Sinem Sidika, ACAR Atılgan Bilgehan

Introduction - Uric acid is a molecule that is known to act as a natural antioxidant in acute oxidative stress conditions such as acute ischemic stroke (AIS). Although there are several studies on the prognostic value of serum uric acid (UA) level, especially the AIS, its importance in ischemic stroke is still controversial. Our aim in this study is to investigate whether the serum UA level is an indicative biomarker in the large-artery atherosclerosis in the AIS etiology. Material and method - Of the patients admitted to Sakarya University Training and Research Hospital Depart-ment of Neurology between January 2017 and November 2017, 91 hospitalized patients, who had AIS diagnosis and had their uric acid levels measured, were analyzed retrospectively. Patients with diabetes mellitus (DM), hypertension (HT), smoking habit, obesity, gout, hyperlipidemia (HL) and renal failure were excluded from the study. Patients were classified as anterior system and posterior system infarct. Then, patients were divided into two groups, one with internal carotid artery (ICA) > 50% stenosis and the other with ICA < 50% stenosis according to carotid-vertebral artery doppler USG examination performed for etiology. Serum UA, total bilirubin, direct bilirubin and indirect bilirubin levels of both groups were statistically compared. Results - In the comparison of serum UA values of ICA>50% stenosis and ICA<50% stenosis group of AIS patients, a statistically significant difference was found between the UA levels (p<0.000), but there was no difference between total bilirubin, direct bilirubin and indirect bilirubin values (p>0.05). Conclusion - High uric acid levels can be considered an independent, indicative risk factor for large-artery disease in AIS.

[The Importance of Teamwork and Patient Education in the Rehabilitation of Stroke Patients]

HORVÁTH Orsolya, STERLIK Krisztina

[The aim of the study: Stroke is an increasing problem in public health. Every year in Hungary tens of thousands of people survive stroke and continue their life bearing all the negative consequences of this disease. Well organized and early rehabilitation treatment, based on the patients’ clinical condition, improves not only their life expectancy, but also quality of life and helps to restore the self- sufficient living as well. The majority of the stroke patients live with numerous of cerebrovascular risk factors, highlighting the special importance of personalized education to prevent the recurrent stroke. Material and Methods: The aim of our investigation was to examine the efficiency of the neuro-rehabilitation teamwork and personalized patient-education among stroke patients took part inpatient rehabilitation of the Teaching Hospital and Rehabilitation Center of Sopron (2016-2017). We measured the change in ability of self- sufficient living with the FIM scale and the Bartel index, while we analyzed the presence of the modifiable cerebrovascular risk-factors with the assistance of a questionnaire was completed by the patient or the relatives (2016-2017). Results: During our research we also evaluated the knowledge of patients about their condition. According to our results the modifiable risk-factors occured cumulatively among our patients and despite the education that stroke patients received during the acute period in the hospital, there still occured a general lack of knowledge regarding their disease. Conclusions: Based on our results the complex rehabilitation therapy started at its earliest possible following the acute period was the most successful method of treatment. During the acute period, the dissemination of written educational materials and information sheets help the recovery phase until the start of the complex rehabilitation therapy. ]
