[Neurological aspects of some sleep disorders]


[My aim is to examine the relation between some sleep disorders and neurological diseases; to analyse their mutual interactions in order to achieve new practical data for clinical use. In the theoretical part I summarise some main points of sleep physiology concentrating on the associations of sleep regulation and neurological diseases. In my examinations, besides clinical methods, the most important tools used are sleep analyses performed by polysomnography and MESAM IV as well as brain imaging methods. To assess clinical state of my stroke patients I utilised NIH Stroke Scale. I found pathological sleep apnoea frequency in more than half of the patients in any type (bleeding/infarction) of acute stroke. In a prospective study, sleep apnoea parameters remain permanent during 3 months in the ischaemic group; on the other hand, sleep apnoea improves during follow up after brain haemorrhages. I showed pathological sleep apnoea frequency in myasthenia gravis among male patients without daytime respiration complaint. I looked for the link between the mechanism of the sleep disorder and the underlying organic lesion in two cases. In this analyses I took into account the function of the affected structure in sleep regulation. I found a basal forebrain tumour, affecting sleep regulating centres underlying severe insomnia and I suggest a neurovascular compression of the lateral preoptic area of the hypothalamus being the reason of sleep related painful erection, a parasomnia of unknown origin.]

[Neuroprotection in brain ischemia - doubts and hopes]


[In ischaemic stroke the two major potential therapeutic strategies are aimed at either improving cerebral blood flow or directly interacting with the cytotoxic cascade - a large body of evidence gained from animal studies is in support of them. In clinical trials direct neuroprotection by blocking the neurotoxic cascade remained ineffective, although there are several clinical trials still in progress. We summarize the experimental data and present the results of clinical trials and also discuss why so many drugs, which were effective in animal studies, failed in human trials. It is emphasized, that 1. in most animal studies the reduction of infarct size, i.e. the amount of saved penumbral tissue, was the outcome measure, whereas neurological function remained unassessed; 2. the recovery of intellectual performance and higher cortical functions are of major importance in the future quality of life in stroke victims; however, it is impossible to examine these parameters appropriately in animal studies; 3. in many clinical trials the patient population was rather heterogenous and low in number, the study protocol was not optimal and the critical analysis of the subacute and chronic phase was lacking or insufficient. We present the major experimental stroke models, discuss their similarities, differencies and limitations as compared to the human pathophysiological processes. The pitfalls of extrapolating data from animal studies to clinical practice are also summarized. The complex network of functional and morphological intercellular connections, the long timescale of neurotoxic and reparative events and the lessons learned from clinical trials suggest, that the use of drug combinations (therapeutic cocktails) targeting multiple steps of the neurotoxic cascade would hopefully result in more effective treatment of ischaemic stroke. Strategies to facilitate brain plasticity and regeneration is an additional promising tool to enhance recovery in brain ischaemia.]

[Epilepsy caused by retrosplenial tumor]


[We present a patient in whom retrosplenial tumour was associated with epileptic symptoms characterized by complex partial seizures and widespread interictal and ictal epileptiform EEG abnormalities The patient had verbal memory deficit symptoms as well. After surgical removal of the tumour (oligoastrocytome) the clinical symptoms and EEG signs disappeared. The characteristics of our patient demonstrate the possible role of the retrosplenial area in widespread epileptic symptoms and in the regulation of secondary bilateral synchrony, in addition to its recently described importance in the memory functions.]

To handle the HaNDL syndrome through a case: The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis


The syndrome of headache with neurologic deficits and cerebrospinal fluid lymphocytosis (HaNDL) is a rare entity. This disease has been related to migrainous headaches. It is a benign, self-limited disorder, which is characterized by fluctuating neurological symptoms and cerebrospinal fluid lymphocytosis. We describe a case of a 47 years old man with acute onset of headache and aphasia. Cerebrospinal fluid analysis revealed a lymphocytic pleocytosis (25 cells/μl, 100% lymphocytes). Electroencephalogram showed moderate slow rhythm in the left hemisphere, with temporoparietal predominance, and without epileptiform activity. His blood tests as well as magnetic resonance imaging (MRI) results were normal. With the diagnosis of HaNDL syndrome the patient was accepted in the Department of Neurology and discharged with full recovery.

[Autoimmune diseases are of multifactorial origin. Due to the disturbed immune tolerance, autoreactive T and B cells target self antigens, which lead to permanent organ damages. Despite of the recently introduced therapeutic protocols, the disease has a chronic course, in many cases with lethal outcome. The efficacy of stem cell therapy has been observed in animal models of autoimmune diseases and in autoimmune diseases associated with haematological disorders. Although this approach has been applied for more than 30 years, its widespread use has been delayed by the serious side effects caused by the conditioning treatments based on oncological protocols. The evaluation of the data of patients who had undergone autologous stem cell therapy revealed that the use of protocols for conditioning treatments that mostly cause lymphoablation, and also, if the procedures are carried out in specialized centres significantly reduce mortality, while the therapeutic efficacy remains optimal. Indications for autologous CD34+ stem cell therapy in patients with autoimmune diseases are internationally established and accepted. New, multicentric investigations have been launched in order to compare the efficacy of various protocols.]

[The history of diuretic treatment in Hungary. Part I. Imre Fodor]

RADÓ János

[The diuretic effect of mercurial compounds was discovered in 1920. However, the term of “mercurial diuresis” was created 36 years earlier by Ernő Jendrassik. Imre Fodor published his experiences with the mercurial diuretic, which has been cited by several authors worldwide. The Hungarian pharmaceutical industry also took its part from the production of the mercurial diuretic with Novurit that proved to be an excellent and worldwide well known preparation in the next 40 years. Even Imre Fodor required the repeated administration of mercurial diuresis because of his severe cardiac oedema in the last period of his life. When the drug became ineffective, i.e. developed refractory oedema, he made a “self-experiment” with the administration of ACTH to restore the sensitiveness to the mercurial diuretic on the basis of most recent American literature at that time. His experience has been published by his colleagues just before his death. Imre Fodor was an eminent clinician, a school creating internist who entered his name into the science dealing with the use of diuretics.]

[A new fix combination therapy in effective cardiovascular prevention]

NAGY András Csaba

[A large amount of literature is available one modern antihypertensive therapy. The experiences of the past 10-20 years have changed clinical practice in many areas of medication and of prevention of complications. Therapy has been revolutionised not only by the new and newer agents but also by the introduction of combined therapy. In this paper, we discuss the use of a new fix-combination antihypertensive drug, with two components (telmisartan and amlodipine) about which excellent evidence is available. We highlight the advantages of this combination therapy in cardiovascular prevention, which is partly explained by better patient compliance due to its favourable side-effect profile.]

[Organic and non-organic perspectives in feeding and eating disorders under three years of age]


[Providing optimal nutrition to infants and toddlers is a critical issue for both parents and experts. Besides the quality and quantity of food, indications of feeding behaviour such as feeding method and acceptance by the child are also crucial when determining feeding issues. The development of self-feeding is a significant part of the healthy somatomental development of a toddler between the age of 0-3 years. Efficient treatment of infants and toddlers with feeding disorders is often challenging in clinical practice. These symptoms frequently appear together with additional behaviour disorders, therefore functional reasons have to be taken into consideration in such cases. Due to the complexity of manifestations, applying tools beyond me­dical competence and involvement of special related professions are necessary. The general diagnostic systems of BNO-10 (International Classification of Diseases) and DSM-V (Statistical Manual of Mental Disorders) which are also applied in our country cannot be used appropriately for clear classification of early childhood feeding disorders and for examination of their backgrounds. DC:0-3R (Diagnostic Classi­fication of Mental Health and Develop­men­tal Disorders of Infancy and Early Childhood- Zero to Three), generally used in Anglo-Saxon countries, can be considered as a complex diagnostic system. Using the DC:0-3R classification system (1), we will present six types of feeding disorders affecting children between the age of 0-36 months in which organic and functional origins have been examined as well. In our article we argue for the complex, psychosomatic interpretation and treatments of early childhood feeding disorders.]
