[INTRODUCTION - In the past few years, a number of studies have been published about acetylsalicylic acid resistance and its potential clinical consequences. PATIENTS AND METHODS - 281 patients with chronic cerebrovascular disease have been involved in our study. The patients were divided in two groups on the basis of their optical aggregometer results (acetylsalicylic acid responder vs. resistant). We compared the risk profiles, drug therapies, laboratory parameters and clinical outcomes of the two groups. RESULTS - Acetylsalicylic acid resistant patients were more likely to be women [23 (45.1%) vs. 92 (40%) (p<0.05)], to smoke (38% vs. 25%), have hypertension (92 vs. 78%), hypercholesterolaemia (5.69 vs. 4.85 mmol/l), and elevated LDL-levels (3.71 vs. 2.85 mmol/l), triglyceride levels (2.78 vs. 1.97 mmol/l) and hsCRP levels (17.89 vs. 7.09 mmol/l) (p<0.01). The use of statins was more frequent (56% vs. 36%) in the responder group (p<0.01). Platelet aggregation values (triggered by agonists) were significantly correlated with cholesterol, LDL, triglyceride and hsCRP levels (p<0.05). Adverse outcomes were reached in 13 (25.5%) acetylsalicylic acid nonresponders and 32 (13.9%) acetylsalicylic acid responder patients (p<0.01). In a multivariate analysis, however, only smoking (OR: 2.38, CI: 1.77-5.44) and increased LDL (OR: 3.01, CI: 2.34-5.67) and hsCRP levels (OR: 2.44, CI: 1.55-7.02) (p<0.05) were independent risk factors of adverse vascular outcomes. CONCLUSION - On the basis of our results, acetylsalicylic acid resistance was associated with a worse clinical outcome, but it was not an independent risk factor of future ischaemic events. Our results implicate that inappropriate prevention therapy might have a role in this phenomenon.]

[Perioperative management of patients with coronary stent undergoing noncardiac surgical procedures - Part II. - Algorythm of emergency and perioperative treatment decisions]

ZIMA Endre, MEZŐFI Miklós, BECKER Dávid, SZABÓ György, MERKELY Béla, PÉNZES István

[The aim of percutaneous coronary intervention (PCI) is to optimise coronary and cardial status, and thus improve short- and long-term outcomes. It is known from large Western databases that stent implantation is performed during 77-85% of coronary interventions, which means hundreds of thousands of patients with new stent every year. The majority of patients need to take dual platelet aggregation inhibitor, namely acetyilsalicylic acid and thienopyridin - most often clopidrogel - following stent implantation. It presents a major therapeutic dilemma when these patients need noncardiac surgery. First, the surgery should be performed with the least blood loss possible, which would be optimally achieved by suspension of the platelet aggregation inhibitor therapy that cannot be stopped during the critical period after stent implantation. Second, stent thrombosis should be avoided, which can only be achieved if platelet aggregation inhibitor therapy is continued. The aim of our paper is to summarise the current professional guidelines and the current risk estimation in the perioperative management of patients with coronary stent. In the second part of the article, we summarise the preoperative preparation of the patient, assessment of coronary status and cardial medication, and the optimal time and location of the surgery. We present the decision principles regarding the risks of perioperative bleeding and stent thrombosis, and the need to continue platelet aggregation inhibitor therapy.]

[Antihypertensive therapy in patients with COPD 699 - The significance of nebivolol]


[The occurrence of hypertension associated with chronic obstructive pulmonary disease (COPD) is increasing. Recognising COPD is important in order to choose the appropriate antihypertensive drugs. Antihypertensive drugs that can be used to treat patients with hypertension and COPD include diuretics, ACE-inhibitors, angiotensine receptor blockers (AT1 receptor antagonists) and calcium antagonists, as well as cardioselective beta blockers, as these drugs decrease total and cardiovascular mortality. Of these agents, the importance of the most cardioselective one, nebivolol should be stressed, as this drug has no clinically significant effect on parameters of respiratory function, and, through its additional effects (namely by increasing the synthesis of NO), it has a beneficial effect on COPD-related deterioration of respiratory functions, haemodynamic alterations (cor pulmonale) and local factors that participate in the respiratory inflammation and endothelial dysfunction.]

[“Boys as victims”, or the potential public health consequences of childhood physical abuse]

GYŐRFFY Zsuzsa, IMOLA Sándor, CSOBOTH Csilla, KOPP Mária

[BACKGROUND - Whereas the scientific literature regarding physical abuse primarily focuses on female victims, few studies have been performed on the childhood abuse of men. The aim of our study was to examine the potential effects of childhood physical abuse of men on adult mental health status. METHODS - Data of 4675 male participants of the Hungarostudy nation-wide representative survey were analyzed. RESULTS - Altogether almost 13% of our study group reported physical abuse by a parent or other significant person. Compared with men who did not report abuse, depression, suicidal thoughts and attempts were significantly more common among abused men. Smoking, alcohol- and drugabuse, anxiety disorders and sleeping disorders also had a higher occurence. Moreover, we established that abused men had a significantly greater risk of marital distress and were more likely to have fewer children. Interpretation of the results in a multivariate model indicated that physical abuse is a determinate and independent risk factor of depression, suicidal thoughts and attempts, smoking habits and alcohol abuse. CONCLUSIONS - Our results underline that childhood physical abuse can have a significant effect on numerous mental disorders and maladaptive behaviours in adulthood. However, the deeper understanding of the relationship between physical abuse and mental disorders necessitates further studies.]

Hyperhomocysteinemia in female migraineurs of childbearing ages


Background and purpose - Migraine is a risk factor for ischemic stroke in women of childbearing ages. Previous researches revealed a higher prevalence of hyperhomocysteinemia in migraineurs. Possible differences on the frequencies of hyperhomocysteinemia between migraine with aura and migraine without aura could contribute the established variances in stroke risk between these migraine types. Therefore, we aimed to search if the frequency of hyperhomocysteinemia was different between these subtypes of migraine or not. Methods - We analyzed the findings of serum homocysteine levels in female migraineurs of 16-49 years old who admitted to our outpatient clinic. Results - Homocysteine level was elevated in 13.3% of study population. There were not any significant differences on median serum homocysteine levels between migraine with aura (8.0 mikromol/L) and without aura (8.5 mikromol/L). (p=0.426) The frequencies of hyperhomocysteinemia were also similar (9.1% versus 16.7%, respectively; p=0.373). Correlation analyses did not reveal any linear correlation between ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura (p=0.417 and p=0.647, respectively). Similarly, any linear correlation between disease ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura was not detected (p=0.359 and p=0.849, respectively). Conclusion - The median serum homocysteine levels and the frequencies of hyperhomocysteinemia are similar between migraine with aura and without aura in women of childbearing ages. Therefore, the variances on stroke risk ratios between these types of migraine are probably not originated from the differences of serum homocysteine status.

[Childhood sporadic type of hemiplegic migraine with arteria cerebri media hypoperfusion]

NAGY Csaba, BAJZIK Gábor, SKOBRÁK Andrea, CSORBA Eszter, LAJTAI Anikó, BALOGH Gábor, NAGY Ferenc, VAJDA Zsolt

[Hemiplegic migraine is a rare subtype of migraine that is associated with reversible motor weakness in the aura phase. This is an uncommon form of migraine usually starting in childhood. The purpose of this case report is to highlight the differential diagnostic difficulty of the first attack. We describe a case, where the fluctuating unilateral motor weakness and aphasia suggested that the patient had ischaemic stroke. Nevertheless the brain MRI and MR angiography, the measured 5-hydroxyindole acetic acid (5-HIAA) concentration changes and the spontaneously improving clinical status proved the diagnosis of hemiplegic migraine. The MRI and MR angiography was very beneficial in establishing the correct diagnosis in this case. To distinguish between the familiar and sporadic type of hemiplegic migraine further genetic tests can be carried out.]

[The high world prevalence of cerebrovascular diseases, and the particularly bad morbidity rates of Hungary are well known. The physiological properties of the brain make stroke prevention outstandingly important. Effective prevention will be reflected in the reduction of the late complications that are otherwise common and expensive to treat. Because of the common simultaneous development of stroke, cardiovascular and peripheral vascular diseases, overall vascular disease prevention is preferred, even if the various vascular diseases manifest in different degrees in a patient. Hungarian data also indicate the high risk of recurrence of cerebrovascular diseases, therefore, the importance of secondary prevention is obvious. Large international studies have proven the strokepreventing effect, and, by a pleiotropic drug action, additional benefits, of the efficient treatment of blood lipid disorders. Consensus conferences in recent years defined clear and even stricter lipid-lowering target values, mostly to be reached by “double inhibition”, bile acid binding resins, fibrates and nicotinic acid derivatives, beside the most common statin treatment. Neurological and stroke departments and clinics play a pivotal role in vascular prevention.]

[Platelet aggregation inhibitors in the prevention of coronary coronary artery disease. „Handle with care!"]

NAGY Viktor

[Platelets play pivotal role in the pathophysiology of unstable angina, acute myocardial infarction and in complications following percutaneous coronary intervention. Three classes of platelet-inhibiting drugs, aspirin, thienopyridines and platelet glycoprotein IIb/IIIa inhibitors are now commonly used for the prevention and treatment of the disorders of coronary artery thrombosis. For the last several decades, aspirin has been the sole option for antiplatelet therapy in the treatment and prevention of the manifestations of cardiovascular disease. However, a wider selection of antiplatelet agents, including the thienopyridines (ticlopidine and clopidogrel) and the platelet glycoprotein IIb/IIIa receptor antagonists are available today. This review summarizes these drugs and scientific data that have led to their use in primary and secundary prevention, unstable angina, myocardial infarction and percutaneous coronary intervention.]

[Evidence-based practice guidelines for nursing and rehabilitation of stroke patients]


[Stroke is a common problem, being the third most frequent cause of death in the United Kingdom and Hungary, accounting for about 20% of bed occupancy. It is also an important cause of morbidity and disability mainly for those aged over 65. As a result, stroke care constitutes as an important part of health services use. Home care services working in the field of stroke rehabilitation have not used a unified evidence-based approach and well-described professional principles and protocols. There was little cooperation between the teams working in the institutional rehabilitation and home care rehabilitation services. No agreed rehabilitation processes, and standardised scales and documentation, showing the change of quality of life, were in use. There were no quality indicators and efficiency measures of nursing and no provision of services either. The Hungarian Nursing Association played a pioneering role in the introduction and dissemination of Evidence Based Nursing in Hungary and in adopting it into routine clinical practice. The successful implementation of the Association's project could be a good example for another field of care and nursing in Hungary and other countries in Europe. Our projects are supported by the Department For International Development (UK) in the framework of the TUDOR project. The Hungarian Nursing Association (HNA) developed a postgraduate training programme entitled "Evidence based nursing in practice". The participants were required to be members of the HNA, have a degree in the field of nursing (nurse teacher, degree nurse, nurse director). Members of the target group were all working in the field of stroke rehabilitation at hospitals or out-patient clinics and home nursing. The Hungarian Nursing Association's professional group developed an evidence based practice guideline for rehabilitation of stroke patients, which was published in the Bulletin of the Ministry of Health (11/2002, 23rd May, 2002). These evidence-based stroke rehabilitation guidelines focused on bladder management, position therapy and patient information.]
