[EEG mapping is a new method which serves for processing the data of the quantitative analysis of the brain electrical activity. In its final form it is a neuroimaging technique. The present study was designed to examine the localization reliability and clinical utilization of the mapping. 103 patients with focal cerebral disorders were investigated: 70 patients with cerebrovascular diseases, 33 patients with tumour, epilepsy, migraine, meningoencephalitis, subdural haematoma, subarachnoid cyst. The EEG mapping, the routine EEG and the CT were performed and their findings were compared. In comparison with the traditional EEG, the mapping has the advantage that it can detect the alpha asymmetry. It shows the focal, functional damages more correctly than the EEG does. The mapping provides information about the ischemic lesions before the CT can visualize the tissue hypodensity. In comparison with the CT, the mapping has a good localization reliability although there are some sources of error in the method. It can detect minimal cerebral damages. It is applicable for follow-up studies on transient ischemic attacks. ]

[Influence of alcohol on the nervous system]

BARACZKA Krisztina

[Prevention and treatment of addictions such as alcoholism require a multidisciplinary approach. Sociological and social psychiatric studies have revealed many factors which may play a part in the development of alcoholism, however biological studies increasingly indicate an organic origin of alcoholism. The aim of the present comprehensive study was to summarise the clinical manifestations of alcohol toxicity based on biological alterations. The results of genetic and immunological studies are summarized. Some aspects of the investigations in the field of biogenic amines are presented. The primary toxic, long lasting withdrawal effects are discussed, from the clinical point of view.]

[Contrast media for magnetic resonance imaging in clinical practice]


[The author's main goal is to introduce the generally available contrast media for magnetic resonance imaging. After a brief survey of this topic, the principal agents are classified into three main subgroups. The four Ti-type contrast agents are compared and discussed on the basis of the available data in the literature. Finally, the possible future direction of contrast media research in MRI is discussed. ]

[Correspondence - The doctor's relationship with patients]


[It's been a decade since I read in a Hungarian medical journal about the doctor's behaviour, his attitude, his relationship with the patient, his colleagues, his co-workers. Based on my decades of medical practice (and my frequent illness - which has only prevented me from practising my profession in the last two years), I will try to summarise what the patient's expectations of the doctor are, and how well the doctor can meet them.]

[MTC-pertechnetate scintigraphy used to identify bleeding from meckel's diverticulum]


[99 mTc-pertechnetate scinti graphy has got an important diagnostic role in pediatrics, as it can detect ectopic ventricular mucosa, and Meckel's diverticulum. In this paper the case of a 12-year-old boy is reported who has presented recurrent rectal bleedings and abdominal pain due to an undiagnosed Meckel's diverticulum for three years. The patient was admitted with serious rectal bleeding and melena. On admission aortography and selective angiography did not give valuable information about the origin of the bleeding. Previous surgical report on laparotomy necessitated by appendicitis at the age of 3,5 years impeded the diagnosis describing the lack of Meckel's diverticulum. The source of bleeding was identified with red blood cell scintigraphy and the presence of Meckel's diverticulum was confirmed with laparotomy. His topathological examination revealed ectopic gastric mucosa in the diverticulum. 99 mTc red blood cell imaging has a valuable diagnostic role in the localization of gastrointestinal bleeding. The examination can be performed repeatedly, and it should be used before aortography and selective angiography. It is emphasized here that Meckel's diverticulum must be considered in any patients presented with rectal bleeding without fever and clinical or laboratory signs of infection or inflammation.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

Sandhoff disease is a rare type of hereditary (autosomal recessive) GM2-gangliosidosis, which is caused by mutation of the HEXB gene. Disruption of the β subunit of the hexosaminidase (Hex) enzyme affects the function of both the Hex-A and Hex-B isoforms. The severity and the age of onset of the disease (infantile or classic; juvenile; adult) depends on the residual activity of the enzyme. The late-onset form is characterized by diverse symptomatology, comprising motor neuron disease, ataxia, tremor, dystonia, psychiatric symptoms and neuropathy. A 36-year-old female patient has been presenting progressive, symmetrical lower limb weakness for 9 years. Detailed neurological examination revealed mild symmetrical weakness in the hip flexors without the involvement of other muscle groups. The patellar reflex was decreased on both sides. Laboratory tests showed no relevant alteration and routine electroencephalography and brain MRI were normal. Nerve conduction studies and electromyography revealed alterations corresponding to sensory neuropathy. Muscle biopsy demonstrated signs of mild neurogenic lesion. Her younger brother (32-year-old) was observed with similar symptoms. Detailed genetic study detected a known pathogenic missense mutation and a 15,088 base pair long known pathogenic deletion in the HEXB gene (NM_000521.4:c.1417G>A; NM_000521:c.-376-5836_669+1473del; double heterozygous state). Segregation analysis and hexosaminidase enzyme assay of the family further confirmed the diagnosis of late-onset Sandhoff disease. The purpose of this case report is to draw attention to the significance of late-onset Sandhoff disease amongst disorders presenting with proximal predominant symmetric lower limb muscle weakness in adulthood.

[Association between cyclothymic affective temperament and hypertension]


[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

[Is the implementation of Vojta therapy associated with faster gross motor development in children with cerebral palsy? ]


[Vojta therapy has been reported as clinically beneficial for strength, movement and gross motor activities in individual cases and is being included within the second of three levels of evidence in interventions for cerebral palsy. The goal of this study is to understand the effect of Vojta therapy on the gross motor function. Our clinical trial followed a one group, pre-post design to quantify rates of changes in GMFM-88 after a two-months period undergoing Vojta therapy. A total of 16 patients were recruited. Post-intervention acceleration rates of GMFM-88-items acquisition (0.005; p<0.001) and Locomotor Stages (1.063; p<0.0001) increased significatively following Vojta the­rapy intervention. In this study, Vojta therapy has shown to accelerate the acquisition of GMFM-88-items and Loco­motor Stages in children with cerebral palsy younger than 18 months. Because functional training was not utilised, and other non-Vojta therapy intervention did not influence the outcome, Vojta therapy seems to activate the postural control required to achieve uncompleted GMFM-88-items. ]

[The aim of this study is to assess the relationship between the physical activity of asthmatics, sleep disorders, the extent of asthma treatment, and to assess the quality of life in terms of physical activity. We conducted our quantitative, cross-sectional survey between 2020-2021. In a non-randomized, comfort sampling the target group was defined as adolescents aged between 14–18 years, their diagnosis of asthma bronchiale had to be for at least 1 year ago. The data were collected by a self-prepared questionnaire, the domains included: socio-demographic questions related to physical activites, symptoms, sleep disorders, severity of asthma. We used miniAQLQ to assess quality of life. The statistical analysis were performed by using Microsoft Excel 2016 and SPSS v 24 programs. Descriptive statistics (mean, standard deviation, minimum, maximum), two-sample t-test, Chi-square test were performed. The mean age of the respondents was 16±1.51, 38% were boys and 62% were girls (N=105). There was no significant difference between physical activity and the frequency of seizures and sleep disorders (p>0.05). There is a significant difference between the genders and the symptoms increasing with intense exercise (p=0.02). We found significant correlation between the active participations in physical education classes and the severity of the disease (p=0.021). There is a significant correlation between moderate-, social activities and physical activity (p<0.05). Appropriate health education, recommendation in career choices as well as in physical activities done by nurses may lead to decrease in the number of suffocation attacks in cases of adolescents suffering from asthma bronchiale.]
