[New data in the classification, diagnostic and in the therapy of cerebrovascular diseases]

NAGY Zoltán

[High stroke morbidity and mortality in Hungary have focused to attention on stroke prevention and the organization of adequate therapy. Up till 1990 both cardiovascular and the cerebrovascular mortality had increased. The Precise analysis risk factors' determines the primary and secondary stroke prevention. The most important issues in of prevention are: proper care of hypertension, gradual change of dietary habits of the Hungarian population, and reduction of smoking. The revised stroke classification, published in 1990 suggested the further breakdown of ischemic strokes into embolic, atherothrombotic and lacunar forms. The new categories reflect the pathomechanism, and thus help in planning more successful treatment. The early treatment of embolic stroke with thrombolysis looks promising, thrombolysis in lacunar stroke implies a certain amount of risk. Hemodilution and dehydration therapy in the treatment of different forms of ischemic strokes need to be evaluated differently. Both invasive and non-invasive diagnostic examinations follow a well thought out algorithmic pattern. Since thrombolysis is a possible therapeutic choice, laboratory tests, especially the analysis of hemostatic factors have gained more significance.]

[NMDA antagonists: possible kinetic and neuroprotective effect with special regard to parkinson's disease]

TAKÁTS Annamária

[The role of excitatory amino acids in the pathomechanism of several neuropsychiatric disorders became known in the last few years. Special attention is paid to glutamate, since this has proved to be an excitotoxin under certain pathological conditions. It acts through the ion-channel of the NMDA receptors via enormous Ca++ ion flow into the cell. NMDA antagonists may be of importance in the treatment of Parkinson's disease, which is characterized by increased glutamate hyperactivity. The clinical use of adamantane derivatives might be suggested because of their possible symptomatic and neuroprotective effect.]

[Arteriovenous malformation and occlusive cerebrovascular disease]

BODOSI Mihály, KUNCZ Ádám, DÓCZI Tamás, BARZÓ Pál, VÖRÖS Erika

[Five rare case histories of intracranial occlusive cerebrovascular disease with arteriovenous malformation are presented. In 2 cases the middle cerebral artery and in a further 2 cases the internal carotid artery were occluded (3 ipsilateral frontal and 1 parietal angiomas). In the fifth case a temporal angioma and ipsilateral posterior cerebral artery occlusion was detected. In the first 4 cases extra-intracranial arterial bypass was performed before the excision of the malformation. ]

[The role of PCR in the diagnosis of duchenne/becker muscular dystrophy]

FODOR Flóra, MECHLER Ferenc, DIÓSZEGHY Péter, ÁDÁNY Róza

[The majority of Duchenne/Becker muscular dystrophy (DMD/BMD) cases are caused by deletions affecting exons of the dystrophin gene, which results in defective protein synthesis. In order to detect deletions the multiplex PCR method was utilized on the DNA of 15 DMD/BMD patients by amplifying 9 deletion-prone exons as a first step followed by a further 5 exons when necessary. Delection were found in more than 50% of patients by this method which correlates well with that expected from the literature data. This rapid and reliable method is an important diagnostic tool in the precise characterization of muscular dystrophies.]

[Fibrinogen as a general risk factor in stroke ]

SZIRMAI Imre, KAMONDI Anita

[Fibrinogen and other laboratory variables of 348 patients with various types of stroke were statistically analysed in the acute, subacute and chronic stage of the disease. Seventy two patients with non-vascular disease served as control. The actual level of plasma fibrinogen in cerebrovascular patients was attributed to the following factors: 1. presence of atherosclerotic plaques in extra and intracranial arteries, 2. the time lag between the onset of stroke and laboratory testing, 3. degre of post stroke mobility of the patients. Initial level of fibrinogen is a predictive value of death both in hemorrhagic and ischemic patients. The highest plasma concentration of fibrinogen was found in the atherothrombotic stroke group, in which was a significant negative correlation between the plasma fibrinogen and high density lipoprotein level. It was concluded that fibrinogen is a risk factor in cerebrovascular diseases.]

[The Comprehensive Aphasia Test in Hungarian]

ZAKARIÁS Lilla, RÓZSA Sándor, LUKÁCS Ágnes

[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]

[A short chronicle of three decades ]

KAPRONCZAY Katalin

[Hungarian professional periodicals started quite late in European context. Their publish­ing, editing and editorial philosophy were equally influenced by specific historical and political situations. Certain breaking points of history resulted in termina­tion of professional journals (War of In­de­pendence 1848-1849, First and Se­cond World Wars), however there were pe­riods, which instigated the progress of sciences and founding of new scientific journals. Both trends were apparent in years after the fall of former Hungarian regime in 1990. The structure of book and journal publishing has changed substantially, some publishers fell “victim” others started successfully as well. The latters include the then-established publishing house Literatura Medica and its own scientific journal, Lege Artis Me­di­cinae (according to its subtitle: New Hun­garian Medical Herald) issued first in 1990. Its appearance enhanced significantly the medical press market. Its scientific publications compete with articles of the well-established domestic medical journals however its philosophy set brand-new trends on the market. Concerning the medical community, it takes on its problems and provides a forum for them. These problems are emerging questions in health care, economy and prevention, in close interrelation with system of public health institutions, infrastructure and situation of those providing individual health services. In all of them, Lege Artis Medicinae follows consequently the ideas of traditional social medicine.]

[History of vaccine production in Hungary ]

ÓCSAI Lajos

[This study presents the complete history of the Hungarian vaccine production, partly in association with the process of fighting vaccine-preventable infectious diseases, and underlines the fact that every government actively contributed to the age-adjusted mandatory vaccination schedule of the past 140 years. It demonstrates the various achievements from the smallpox lymph production through the launch of diphtheria serum production at Phylaxia and the establishment of the National Public Health Institute (OKI) with its vaccine production and the later institutional transformation of OKI into Humán as economic corporation to its closure. Among all OKI’s vaccine production activities, this study focuses on the production of influenza vaccines, due to its international importance in the 1960s and 1970s. The vaccine production against diphtheria tetanus and pertussis stands out from Humán’s activities, and the tetanus component of this vaccine is still used in the products of a multinational vaccine manufacturer. ]

[Diagnosis and treatment of microvascular coronary heart disease. Specialities of conditions in Hungary]

SZAUDER Ipoly

[Invasive investigations show that in two-thirds of patients the myocardial ischaemia persists without obstructive coronary disease and any other heart conditions (INOCA). The underlying cause may be microvascular dysfunction (CMD) with consecutive microvascular coronary disease (MVD) and microvascular or epicardial vasospastic angina (MVA). The modern practice of clinical cardiology while using the developed non-invasive cardiac imaging permits exact measuring of the coronary flow with its characteristic indices. All of these improve the diagnosing of CMD-induced myocardial ischemia and provide opportunity to determine primary MVD cases. Since the recognition and treatment of MVD is significantly underrep­resented in the Hungarian medical care, the primary stable microvascular angina (MVA) is described in detail below with its modern invasive and non-invasive differential diagnosis and treatment, concerning especially its frequency provoked by high blood pressure and female coronary heart diseases. There are highlighted all recommended diagnostic procedures available under domestic conditions.]
