[CURRENT PRACTICAL VACCINOLOGY]

JELENIK Zsuzsanna

[The author deals with the current situation and new trends of vaccinology by focusing on the interests of practitioners. The main topics are the changes of antigens (such as pertussis, measles, or poliomyelitis) to provide better efficacy and milder reactogenity or less adverse events. Purifying the vaccines, like thiomersal and human proteins free vaccines is another proven method to achieve better safety. New antigens e.g. Rota, Lyme, meningococcus B are in the pipeline of vaccinology. The aim of producing a combined vaccine is to achieve immunity against more diseases with less inconvenience for the patient, while achieving higher vaccine coverage (DPT-Hib-HBV-IPV). The epidemiological and clinical experiences will influence the current vaccine schedule such as revaccinations of MMR, and remove the need for revaccinations of BCG and hepaB. The special target groups of immunizations are the elderly and patients with chronic disease. Groups of specialists are working on the vaccine recommendation guidelines for certain risk groups. At the same time, with the successful eradication of polio in Europe the practitioners now have to face the antivaccination movement, as well. The main tools to convince people about the benefit of vaccinations are health education and information.]

[TRANSBRONCHIAL NEEDLE ASPIRATION IN THE DIAGNOSIS OF SARCOIDOSIS]

ZSIRAY Miklós, BADÁR Éva, UDUD Katalin, FÜLÖP Andrea, SZABÓ Zsuzsanna, MATESZ István, MARKÓCZY Zsolt

[INTRODUCTION - The histological pattern of sarcoidosis and cytological characteristics are similarly unspecific. Nevertheless, both forms of the diagnosis based on morphology can be taken into consideration if the clinical picture and chest X-ray respectively, are fitted and other diseases are excluded. PATIENTS, METHOD AND RESULTS - Enlargement of hilar lymph nodes is present in 80% of cases of sarcoidosis. In this study, transcarinal needle aspiration combined with rapid on-site cytological staining was performed in the case of 33 patients with I. or II. stage of sarcoidosis. The sensitivity was found to be 76%. CONCLUSION - Since the cytologist can inform the bronchologist fairly soon: during the bronchoscopy, bronchial mucosal biopsies or transbronchial lung biopsies are only necessary to obtain in about quarter of patients.]

[COST-EFFECTIVENESS OF PIMECROLIMUS CREAM - A NEW TREATMENT FOR ATOPIC DERMATITIS IN HUNGARY]

KÓSA József, HUNYADI János, SZALAI Zsuzsanna, KÖRMENDY Miklós, KALÓ Zoltán

[OBJECTIVE - To assess the costs, consequences and cost-effectiveness of pimecrolimus cream 1% in the treatment of children with atopic dermatitis in Hungary. METHODS - A Markov-model for atopic dermatitis developed by the Erasmus University (Rotterdam, the Netherlands) was adopted to the Hungarian health care setting. The model is based on a double-blind, multicenter, randomized, parallelgroup study. Patients were randomised (2:1) to receive pimecrolimus treatment (i.e. emollients, pimecrolimus, medium potency topical corticosteroids) or standard of care (emollients, vehicle, medium potency topical corticosteroids). The study was conducted in children and adolescents (2 to 18 years of age). Hungarian cost vectors were calculated by linking severity of disease as defined by Investigator’s Global Assessment (IGA) to average resource use. Resource use was multiplied by drug costs and unit costs as published in official databases. RESULTS - Pimecrolimus treatment has an incremental cost of HUF 143 897 over standard care. This additional cost of care resulted in an incremental 0.05 QALY gain over the 6 months period. The incremental cost effectiveness ratio was 2 863 913 HUF/QALY for the pimecrolimus therapy. CONCLUSION - Pimecrolimus is more costeffective than many other health care interventions currently reimbursed by the Hungarian National Health Fund.]

[THE ANALYSIS OF LIFE EVENTS IN HUNGARY]

NAGY Judit

[INTRODUCTION - In the social vulnerability model the concept of Life Events is the measure of forces and life events presenting in the social field that makes someone susceptible to mental illnesses. The stress value of these events add up. The Life Events Scale by Paykel is a questionnaire used in international practice. The objective of this study is the Hungarian adaptation and introduction of the Life Events Scale in the national practice, the international comparison of our results, the comparison of healthy people with the patient population and the analysis by social data. PATIENTS AND METHOD - The questionnaires were filled in by both healthy people and different patient populations. The participants rated the life events between 0-7 points according to their degree of causing stress, then they indicated whether it had happened with them. This was followed by a questionnaire about social data. We separated question groups by factor analysis: losses, changes, failures, difficulties, joyful events. RESULTS - When making the international comparison we only found differences in two areas: becoming unemployed and infidelity/divorce. Young people scored losses higher, while older ones scored changes higher. Those who declared themselves as religious scored suicide attempts higher. The mean scores of patient populations were higher compared to healthy subjects. The number of life events occurred was the highest in the depression-suicide attempt group. CONCLUSION - Our results can be used in everyday clinical practice and may be extremely important in suicide prevention.]

[Zonisamide: one of the first-line antiepileptic drugs in focal epilepsy ]

JANSZKY József, HORVÁTH Réka, KOMOLY Sámuel

[Chronic administration of antiepileptic drugs without history of unprovoked epileptic seizures are not recommended for epilepsy prophylaxis. Conversely, if the patient suffered the first unprovoked seizure, then the presence of epileptiform discharges on the EEG, focal neurological signs, and the presence of epileptogenic lesion on the MRI are risk factors for a second seizure (such as for the development of epilepsy). Without these risk factors, the chance of a second seizure is about 25-30%, while the presence of these risk factors (for example signs of previous stroke, neurotrauma, or encephalitis on the MRI) can predict >70% seizure recurrence. Thus the International League Against Epilepsy (ILAE) re-defined the term ’epilepsy’ which can be diagnosed even after the first seizure, if the risk of seizure recurrence is high. According to this definition, we can start antiepileptic drug therapy after a single unprovoked seizure. There are four antiepileptic drugs which has the highest evidence (level „A”) as first-line initial monotherapy for treating newly diagnosed epilepsy. These are: carbamazepine, phenytoin, levetiracetam, and zonisamide (ZNS). The present review focuses on the ZNS. Beacuse ZNS can be administrated once a day, it is an optimal drug for maintaining patient’s compliance and for those patients who have a high risk for developing a non-compliance (for example teenagers and young adults). Due to the low interaction potential, ZNS treatment is safe and effective in treating epilepsy of elderly people. ZNS is an ideal drug in epilepsy accompanied by obesity, because ZNS has a weight loss effect, especially in obese patients.]

[Interdisciplinary approach of vestibular system impairment]

PONGRÁCZ Endre

[In the first part of this review the definition of vertigo/dizziness was discussed. The major difference between the two signs is the exsistence of the direction, which is specific for vertigo. Dizziness is a frequent complaint in the clinical practice. Its frequency is increasing with advance of age, to intimate the play of declining cognitive process in the pathogenesis of its. The popular health significance of vertigo is in the rowing number of the patients. The onset of the most cases with acute vertigo appears between secundums and minutes so the patients will be provided in circumstances of emergency department. First of all three form schould be take into account: neuronitis vestibularis, benign paroxysmal positional vertigo and Meniere syndrome. Without tipical periferal signs of vertigo, central cause should be searched, principally stroke (lysis possibility). The differential diagnose of the different dizzeness/vertigo forms according to the elapsed time of the onset or congenital and acquired nystagmus was created in tables. The recommendations of the therapy of acute and chronic dizziness/ vertigo syndroms are, lack of results of evidence based trials doubtful. The more often used drugs based on clinical trials are discussed as vinpocetine, betahistine and piracetam. The in vitro and in vivo data suggest that the last molecule is eligible to use both in periferal and central type of vertigo syndroms.]

[Clinical neurophysiological methods in diagnosis and treatment of cerebrovascular diseases]

NAGY Ildikó, FABÓ Dániel

[Neurophysiological methods are gaining ground in the diagnosis and therapy of cerebrovascular disease. While the role of the EEG (electroencephalography) in the diagnosis of post-stroke epilepsy is constant, quantitative EEG para-meters, as new indicators of early efficiency after thrombolysis or in prognosis of patient’s condition have proved their effectiveness in several clinical studies. In intensive care units, continuous EEG monitoring of critically ill patients became part of neurointenzive care protocols. SSEP (somatosesnsory evoked potencial) and EEG performed during carotid endarterectomy, are early indicative intraoperativ neuromonitoring methods of poor outcome. Neurorehabilitation is a newly discovered area of neurophysiology. Clinical studies have demonstrated the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in the rehabilitation of stroke patients. Brain computer interface mark the onset of modern rehabi-litation, where the function deficit is replaced by robotic tehnology. ]

[Vinpocetin in neurological diseases]

SZAPÁRY László, KÉSMÁRKY Gábor, TÓTH Kálmán, MISNYOVSZKY Melinda, TÓTH Tímea, BALOGH Ágnes, NAGY Krisztián, NÉMETH György, FEHÉR Gergely

[Introduction - Stroke is the third leading cause of death worldwide (following cardiovascular and cancer mortality) and associated with serious disability for the vast majority of patients. There is no salvage therapy for irreversibly damaged brain areas, improving the circulation of the surrounding hypoperfused territories may be associated with benefitial clinical states. Cerebral hypoperfusion may play a role in the pathogenesis of other kind of neurological diseases, improvement of global circulation may have a preventive effect on these conditions. Aims - The aim of our study was to review the experimental and clinical articles focusing on the role of vinpocetin in different neurological conditions. Results - Vinpocetin appears to have several different mechanisms of action that allow for its antiinflammatory, antioxidant, vasodilating, antiepileptic and neuroprotective activities in experimental conditions. On the other hand, several meta-analysis of the existing studies in acute stroke examining short and long term fatality rates with vinpocetin was unable to assess efficacy. In chronic cerebrovascular patients, vinpocetin improves impaired hemorheological variables, has significant vasodilating properties, improves endothelial dysfunction, neuroimaging studies showed selective increase in cerebral blood flow and cerebral metabolic rate, all of which are potentially beneficial in cerebrovascular disease and may improve cognitive functions. Summary - Based on the above mentioned results vinpocetin plays an important role both in basic research and in clinical management of different neurological diseases.]

Risk factors for ischemic stroke and stroke subtypes in patients with chronic kidney disease

GÜLER Siber, NAKUS Engin, UTKU Ufuk

Background - The aim of this study was to compare ischemic stroke subtypes with the effects of risk factors, the relationship between grades of kidney disease and the severity of stroke subtypes. Methods - The current study was designed retrospectively and performed with data of patients who were hospitalised due to ischemic stroke. We included 198 subjects who were diagnosed with ischemic stroke of Grade 3 and above with chronic kidney disease. Results - In our study were reported advanced age, coronary artery disease, moderate kidney disease as the most frequent risk factors for cardioembolic etiology. Hypertension, hyperlipidemia, smoking and alcohol consumption were the most frequent risk factors for large-artery disease. Female sex and anaemia were the most frequent risk factors for small-vessel disease. Dialysis and severe kidney disease were the most frequent risk factors in unknown etiologies, while male sex, diabetes mellitus, prior stroke and mild kidney disease were the most frequent risk factors for other etiologies. National Institute of Health Stroke Scale (NIHSS) scores were lower for small-vessel disease compared with other etiologies. This relation was statistically significant (p=0.002). Conclusion - In order to improve the prognosis in ischemic stroke with chronic kidney disease, the risk factors have to be recognised and the treatment options must be modified according to those risk factors.
