Clinical Neuroscience - 2008;61(07-08)

[Statin’s treatment clearly is authorized in prevention of coronary heart disease (CHD). According to the results of many studies and meta-analyses statins can inhibit the first cerebrovascular infarct (stroke). The greater the decrease of LDL-cholesterol level the more prominent the efficacy. The effect is not so robustic compared to coronaria vessels moreover clear pleiotropic (cholesterol independent) action takes also part. It has been nowadays revealed that high dose (80 mg) atorvastatin can confine first time the development of recurrence stroke (SPARCL study), which is an important fact in the field of secondary prevention.]

[IDIOPATHIC TOLOSA-HUNT SYNDROME: FOUR ADDITIONAL CASES]

KIRBAS D, TOPCULAR B, OZCAN ME, KARAGOZ Sakalli N, GUL G, KALYONCU Aslan I

[Idiopathic Tolosa-Hunt syndrome (ITHS) is a very rare cause of painful ophthalmoplegia characterized by unilateral orbital pain, ipsilateral oculomotor paralysis and prompt response to steroids. In this paper we report 4 additional cases of ITHS. This rare cause of painful ophthalmoplegia effects the cranial nerves due to a granulomatous lesion of unknown etiology in the cavernous sinus or superior orbital fissure. The International Headache Society redefined the diagnostic criteria for ITHS but it is still mostly a diagnosis of exclusion. Careful evaluation and follow-up is essential for diagnosis. Optimal therapy duration and dosage and prophylactic treatment in recurrent cases needs further research.]

[SUCCESSFULL SURGICAL REMOVAL OF A MESENCEPHALIC CAVERNOUS ANGIOMA, WHICH WAS RESPONSIBLE FOR PROGRESSIVE NEUROLOGICAL DEFICITS]

ZSOLDOS Tamás, MOLNÁR Anna, JÁNOSSY Ágota, KUNCZ Ádám, NAGY Ernő, DEÁK Gábor, BARZÓ Pál

[Cavernous angiomas comprise 5-10% of all vascular malformations in the central nervous system, occuring most frequently in the supratentorial region, and 20% of them in the brain stem. According to literature, brain stem cavernous angiomas occur most frequently in the pons (60%), and equally in the mesencephalon (20%) and in medulla oblongata. In clinical evaluation the authors describe the successful removal of a mesencephalic cavernous angioma causing progressive neurological deficits and symptoms. The authors present a case of a 51 year old female, who had developed 1 year prior to her admittance: fatigue, weakness in the right upper limb and fingers, right lower limb ataxia. One month later, her lower right limb developed sensory deficits. The first neurological exploration indicated dysarthria, moderate facial and right hemiparesis, hemihypaesthesia and ataxia. CT and MR imaging indicated multilobulated cavernomas in the mesencephalon. After conservative treatment the patient became almost symptom free, and thus neurosurgical treatment was not discussed. Later on her symptoms fluctuated, but after 6 month she suddenly developed progressive right hemiparesis, right facial weakness, serious dysphasia, and emotional incontinence combined with continuous spastic sobbings. The controll MRI showed enlargement of the cavernomas and new extravasation. Surgery was indicated for removing the cavernomas. The left infratentorial, supracerebellar approach revealed a blood engorged cavernoma in the center of the mesencephalon, almost dividing it. The cavernomas and accompanying haematoma was exstirpated. The patient's neurological symptoms rapidly improved after surgery, her dysphasia as well as motor weakness have disappeared. Six days after surgery, we discharged a neurologically symptomless and self-supporting patient. The literature and the presented case indicates that the correct timing and proper surgery allows brain stem cavernomas to be safely removed, or significantly bated, which results in the massive regression of neurological symptoms.]

[LIPID LOWERING IN ACUTE CORONARY SYNDROME]

MÁRK László

[A large number of studies have proved that in acute coronary syndrome the administration of statins improves clinical outcome by their lipid lowering effect, and also by stabilizing the plaque as part of their pleiotropic effects. An important question regarding statin therapy is when it should be introduced after the onset of symptoms. Studies on this issue agree that statin therapy should be initiated right after the onset of acute symptoms. If the patient is already receiving statin, we must make sure it is not abandoned. According to current Hungarian guidelines, for patients with acute coronary syndrome the target level of the low density lipoprotein cholesterol is 1.8 mmol/l.]

[THE EPIDEMIOLOGY OF CEREBROVASCULAR DISEASES IN HUNGARY AFTER THE MILLENNIUM]

VOKÓ Zoltán, SZÉLES György, KARDOS László, NÉMETH Renáta, ÁDÁNY Róza

[INTRODUCTION - Here we present the descriptive epidemiology of stroke in Hungary including mortality, morbidity, functional limitation and inpatient care based on the most recent health statistical data. METHODS - Mortality data were analysed by direct and indirect standardisation, and geographical mapping based on empirical Bayesian smoothing. Morbidity data were obtained from the General Practitioners’ Morbidity Sentinel Station Program and the National Health Surveys. The latter also provided data on functional limitation. Data on inpatient service were taken from the European Hospital Morbidity Database of WHO. RESULTS - Hungarian stroke mortality continued to decrease in recent years, and the slope of the decrease was larger than in Western Europe. Stroke mortality was highest in the Northern- Hungarian Region, and in Somogy and Zala counties. The incidence of stroke was 1.5-2 times higher than in the developed countries in most age groups. Over 64 years of age, a decline of stroke incidence was observed, especially in men. In this age group approximately 10% of men and 7% of women had already had a stroke. Of these patients more than 10% needed assistance to get out of the bed, dress up, or eat. Hospitals reported more than 60 000 stroke cases in 2005. CONCLUSION - Despite the promising trends in stroke mortality and now also in morbidity, both indices are still rather high in Hungary compared to those in Western-Europe. The relatively favourable epidemiological changes, however, may be overridden by the increased stroke burden resulting from the aging of the population.]

[THE IMPORTANCE OF THE RECOGNITION AND TREATMENT OF LIPID METABOLISM DISORDERS IN THE SECONDARY PREVENTION OF CEREBROVASCULAR DISEASES]

FOLYOVICH András, HORVÁTH Eszter

[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.]

[Paradigm shift in management of patients with vertigo and imbalance]

MIKE Andrea, TAMÁS T. László

[Dizziness is one of the most common causes of medical visits. Management of the dizzy patient may be challenging both for the general practitioner, in emergency departments, and special clinics, as behind a seemingly homogeneous clinical presentation several very different etiologies may occur. Research of the last two century enriched our knowledge about physiology and pathophysiology of the vestibular system. Much knowledge is now available about the labyrinth being able to sense head motions and gravity, processing of afferent vestibular stimuli, reflectory oculomotor and postural control, or recovery of the vestibular system. Based on scientific results new beside tests have been introduced including provocation maneuvers for detecting ectopic otoliths in different semicircular canals, head impulse test to examine function of the vestibulo-ocular reflex, and the HINTS+ battery for differentiation of peripheral or central origin of an acute vestibular syndrome. Technical innovations like videooculography and vestibular evoked myogenic potentials enable us to selectively and side-specifically examine the function of all six semicircular canals and two otolith organs. Pathomechanism of disorders with vertigo and dizziness became more clear resulting in the development or amendment of diagnostic criteria of several vestibular disorders including vestibular migraine, Menière’s disease, benign paroxysmal positional vertigo, persistent postural-perceptual dizziness, bilateral vestibulopathy. Broader knowledge about the pathomechanism promoted the development of new therapeutic methods like different repositioning maneuvers in benign paroxysmal positional vertigo, pharmaceutical therapies, vestibular rehabilitation, and psychotherapy. We aimed to summarize the novelties in the field of oto-neurology.]

[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. ]
