[INTRODUCTION - Mixed connective tissue disease (MCTD) is an inflammatory autoimmune disease with multiple organ involvement. Immune- inflammatory processes play a crucial role in the pathogenesis of atherosclerosis. The connection between inflammatory parameters and atherosclerosis in MCTD has not yet been studied. Lipid abnormality is an important risk factor of atherosclerosis. Among the lipids, HDL is protective, which is in part due to the antioxidant effect of paraoxonase. In this paper, the lipid profiles and paraoxonase activities of MCTD patients were studied and the factors causing abnormalities were investigated. PATIENTS AND METHODS - Thirty-seven patients with MCTD, who had not taken any lipid lowering drugs in the past 2 months, were enrolled in the study. Thirty healthy individuals served as controls. At the time of the study the mean age of the MCTD patients was 51.2 ± 9.5 years, and the mean disease duration was 11.0 ± 7.2 years. Paraoxonase activity was determined by spectrophotometry, lipid profiles were determined by a Cobas Integra 700 Analyser, the von Willebrand factor antigen (vWFAg) was measured by turbidimetry in platelet-poor plasma and the thrombomodulin and anti-endothelial cell antibody (AECA) measurements were carried out by ELISA methods. RESULTS - Paraoxonase activity in the MCTD patients was lower than in the control population (118.5 ± 64.6 U/l vs. 188.0 ± 77.6, p<0.001). The arylesterase activity was also significantly lower in the patients (p<0.001). The reduction of paraoxonase activity was in correlation with the age of the patients, the duration of the disease and with vascular (eye, cardiac, cerebral) disorders. The total cholesterol and triglicerid levels of the patients were significantly increased compared to the control group, while in the apoA1 levels a significant reduction was seen. A very strong correlation was observed between the reduction of paraoxonase activity and the increase of endothelial cell activation markers (thrombomodulin, vWFAg, AECA). There was no difference in the values of patients with or without corticosteroid treatment. CONCLUSIONS - The results suggest that in MCTD there is an increased risk for atherosclerosis. Apart from an elevated cholesterol and triglicerid level, a reduced paraoxonase level and activity may also play a role in the development of atherosclerosis,. Therefore, in patients with MCTD, due to the increased oxidative processes and the impaired elimination of free radicals, a sustained damage to the endothelial cells occurs, which is indicated by increased levels of thrombomodulin, vWFAg, and anti-endothelial antibody.]

[INTRODUCTION - ’The cycle of violence’ have long been a known phenomenon. The present research is aimed at answering the question of whether abuse suffered in childhood creates a tendency to aggressive behaviour in adulthood and whether there is a connection between these two forms of behaviour. METHODS - The sample studied comprised 235 clinically treated alcoholics. The instruments used for the investigation were the European Addiction Severity Index (EuropASI), the Buss and Perry Aggression Questionnaire, and the Janus Questionnaire. RESULTS - The most important finding is that persons who were physically abused in childhood by their parents were very likely to strike or beat someone in the course of their lives (χ2=9.79, p<0.001). Within the most aggressive group, 18 % had not suffered abuse in childhood, while 81 had been abused (χ2=13.25, p<0.001). If the patient had been physically abused, struck or beaten, that person later abused, struck or beat someone else (Pearson r=.397). CONCLUSION - The results draw attention to the importance of preventing and treating aggression in alcoholics undergoing clinical treatment.]

Neuroscience highlights: Main cell types underlying memory and spatial navigation

KRABOTH Zoltán, KÁLMÁN Bernadette

Interest in the hippocampal formation and its role in navigation and memory arose in the second part of the 20th century, at least in part due to the curious case of Henry G. Molaison, who underwent brain surgery for intractable epilepsy. The temporal association observed between the removal of his entorhinal cortex along with a significant part of hippocampus and the developing severe memory deficit inspired scientists to focus on these regions. The subsequent discovery of the so-called place cells in the hippocampus launched the description of many other functional cell types and neuronal networks throughout the Papez-circuit that has a key role in memory processes and spatial information coding (speed, head direction, border, grid, object-vector etc). Each of these cell types has its own unique characteristics, and together they form the so-called “Brain GPS”. The aim of this short survey is to highlight for practicing neurologists the types of cells and neuronal networks that represent the anatomical substrates and physiological correlates of pathological entities affecting the limbic system, especially in the temporal lobe. For that purpose, we survey early discoveries along with the most relevant neuroscience observations from the recent literature. By this brief survey, we highlight main cell types in the hippocampal formation, and describe their roles in spatial navigation and memory processes. In recent decades, an array of new and functionally unique neuron types has been recognized in the hippocampal formation, but likely more remain to be discovered. For a better understanding of the heterogeneous presentations of neurological disorders affecting this anatomical region, insights into the constantly evolving neuroscience behind may be helpful. The public health consequences of diseases that affect memory and spatial navigation are high, and grow as the population ages, prompting scientist to focus on further exploring this brain region.

[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.]

Purpose - Methylation is a key epigenetic modification of DNA and regarding its impact on epilepsy, it is argued that “DNA methylation may play an important role in seizure susceptibility and maintenance of the disorder”. DNA methylation status of KCC2 (SCL12A5) and NKCC1 (SCL12A2) associated with refractory temporal lobe epilepsy was investigated in our study. Materials and methods - Thirty-eight patients with temporal lobe epilepsy (TLE) who were diagnosed by video EEG monitoring and 32 healthy control subjects were included in the study. Twenty-three patients in TLE group were men and the remaining 15 were women. Among them, 27 had unilateral temporal focus (9 with right; 18 with left) and 11 patients had bilateral TLE. We analyzed promoter region methylation status of the KCC2 (SCL12A5) and NKCC1 (SCL12A2) genes in the case and control groups. Gene regions of interest were amplified through PCR and sequencing was accomplished with pyro-sequencing. Results - We found a significant relationship between TLE and methylation on the NKCC1. However, there was no association between TLE and methylation on the KCC2 gene. Also, we found no association between right or left and unilateral or bilateral foci of TLE. There was no relationship between TLE and methylation on the NKCC1and KCC2 genes in terms of mesial temporal sclerosis in cranial MRI, head trauma or febrile convulsions. Conclusion - The methylation of NKCC1 can be a mecha­nism of refractory temporal lobe epilepsy. There are limited findings about DNA methylation in TLE. Therefore, further studies with large sample sizes are necessary.

[Celiac disease - in its typical form - is a chronic immunemediated enteropathy with typical clinical symptoms that develops against gliadin content of cereal grains, and is often associated with other autoimmune diseases. In cases of atypical manifestation classic symptoms may be absent or mild, and extra-intestinal symptoms or associated syndromes dominate clinical picture. The authors present a longitudinal follow-up of such a case. A 63-years old woman was diagnosed with epilepsy at the age of 19, and with progressive limb ataxia at the age of 36, which was initially thought to be caused by cerebellar atrophy, later probably by stiff person syndrome. At the age 59, her diabetes mellitus manifested with type 2 diabetic phenotype, but based on GAD positivity later was reclassified as type 1 diabetes. Only the last check-up discovered the celiac disease, retrospectively explaining the entire disease course and neurological symptoms. By presenting this case, the authors would like to draw attention to the fact that one should think of the possibility of celiac disease when cerebellar ataxia, progressive neurological symptoms and diabetes are present at the same time. An early diagnosis may help to delay the progression of disease and help better treatment.]

[Avoiding unlimited energy drink consumption is a matter of our heart]


[Energy drinks have been gaining unbroken popularity, especially among youngsters and children since they were introduced to the market. Manufacturers promise to improve performance and stamina with consuming the products, classified as non-alcoholic soft drinks. In addition to the vitamins and plant extracts, they contain a significant amount of caffeine and other stimulants (taurine, guarana). Among the active ingredients, caffeine has an outstanding effect and thereby a danger, since its overconsumption – in addition to milder he­mo­dynamic changes – can cause severe cardio­vascular consequences, cardiac arrhythmias, ion channel diseases, increased blood coagulation, myocardial infarction or reduced cerebral blood flow in susceptible consumers. Many case studies have also reported serious cardiovascular attacks among young chronic energy drink consumers. Health impairments of excessive and long-term consumption of energy drinks have been studied increasingly, however there is limited and contradictory evidence on the safety of consumption and the effectiveness of performance enhancement. ]
