[Pompe’s disease - Part II - Treatment strategies and enzyme replacement]

ILLÉS Zsolt, VÁRADI VISY Katalin

[Pompe’s disease is an ultra-orphan disease caused by the deficiency of lysosomal alpha-glucosidase. At present, it is the only inherited muscle disorder, which can be treated by replacement of the enzyme. Three international randomized trials examined the clinical efficacy of enzyme replacement therapy (ERT) in infantile and late-onset diseases. ERT reduced the risk of death, respiratory support, invasive ventilation and improved cardiomyopathy. Respiration, muscle function and quality of life were improved in both infantile and late-onset diseases. These randomized and pilot trials also proved the safety of the treatment. At present it is not clear if antibodies induced by ERT result in decreased efficacy. In this review, we also discuss our experiences obtained by the treatment of three patients, and review the spectrum of supportive and experimental treatment strategies.]

[Objectives - To investigate interhemispheric propagation of mesial temporal lobe epilepsy seizures in patients undergoing long-term video-EEG monitoring with combined scalp and foramen ovale electrodes. Aim of the study - To reveal possible interhemispheric propagation patterns in mesial temporal lobe epilepsy, to improve presurgical evaluation of temporal epileptic patients. Methods - Sixty-five seizures from 20 patients were analyzed. We defined two contralateral seizure propagation patterns: Type I for those seizures that spread to the contralateral foramen ovale electrodes earlier than to the contralateral scalp electrodes, and type II for the opposite. Participants - Twenty drug resistant epileptic patients were investigated in frame of their presurgical evaluation. Results - The majority of seizures (80%) were classified as type I. Inter-foramen ovale electrode propagation time was significantly shorter for type I compared to type II seizures. Ninety percent of patients had either type I or type II seizures only. Patients with type I seizures significantly more often had mesiotemporal structural alterations evident on magnetic resonance imaging scans, and became more often seizure-free after surgery compared to patients with type II seizures whose surgical outcome was less favorable or surgery could not be indicated because of independent bilateral ictal seizure-onset. Conclusions - The two types of contralateral propagation patterns we are describing seem to represent two subtypes of mesial temporal lobe epilepsy with different morphological and prognostic features. The predominance of type I over type II seizures together with shorter propagation times for type I seizures indicate a role of a more direct and dominant interhemispheric pathway in mesial temporal lobe epilepsy.]

[Actigraphy: A valuable diagnostic tool or a luxury investigation? (Neuropsychiatric aspects)]

RAJNA Péter, SZOMSZÉD Anita

[Aim - Despite of the continuing interest in actigraphy it has a relatively low impact on the everyday medical routine. Accordingly, we set out to review the current state and to recommend relevant further indications for its application, especially in neuropsychiatry. Method - We surveyed the areas of its use and then reviewed the literature, with special regard to its advantages and methodological limitations. Adding to the results we enlarged the results with our own personal experience. Results - The limitations of the method may be decreased by methodological manipulations (a simple rational data reduction is recommended). Actigraphy appears to be a useful tool in the diagnosis of illnesses, syndromes or disorders influencing the vigilance level, the motor performance or the energetic balance of the organism. We constructed a list of the most relevant fields of indication of actigraphy in diagnostics, illustrated by anecdotal actigraphic case records. Conclusion - Further methodological considerations are needed for the successful evaluation of accelerometry. Targeted basic epidemiological studies in the healthy population and in patient groups should solve various open questions in order to make full use of the advantages of actigraphy in the everyday clinical routine.]

[The transcription of the amyloid precursor protein and tryptophan 2,3-dioxygenase genes are increased by aging in the rat brain]

KÁLMÁN Sára, PÁKÁSKI Magdolna, SZŰCS Szabina, GARAB Dénes, DOMOKOS Ágnes, ZVARA Ágnes, PUSKÁS László, BAGDY György, ZELENA Dóra, KÁLMÁN János

[Aging itself is considered as a major risk factor of dementia. The prevalence of the Alzheimer’s disease (AD) is increasing exponentially after the age of 65 and doubles every 5 years. The major aim of our present research was to examine the effect of aging on the transcription of certain genes associated with neurodegenerative disorders in the rat brain. The influence of the vasopressin (VP) hormone was also examined in the same experimental paradigm. Age dependent transcriptional changes of the following four genes were examined in the cerebral cortex: the first was the gene of the amyloid precursor protein (APP) which is abnormally cleaved to toxic beta-amyloid fragments. These aggregated peptides are the major components of the senile plaques in the AD brain. The second one was the mitogen-activated protein kinase (MAPK1) gene. The MAPK is involved in the abnormal hyperphosphorylation of the tau-protein which results in aggregated neurofibrillary tangles. The beta-actin gene was the third one. The protein product of this gene is considered to be involved in synaptogenesis, neuronal plasticity and clinical conditions like depression and AD. The last one was the gene of the tryptophan 2,3-dioxygenase (TDO2) enzyme. The activity of this enzyme is considered as a rate limiting factor in the metabolism of the neuro-immune modulator quinolinic acid (QUIN). The transciptional activity of young (2.5 months) and aged (13 months) Brattleboro rats with or without VP expression were compared by means of real time PCR technique. The cortical transciptional activity of the APP and TDO2 genes were increased in the aged animals as compared with the activity of the young ones, and this effect was independent on the presence of the VP. Our results indicate the importance of certain age dependent transcriptional changes might influence the mechanism of AD and other neurodegenerative disorders.]

[Association between cyclothymic affective temperament and hypertension]

NEMCSIK János, BATTA Dóra, KŐRÖSI Beáta, RIHMER Zoltán

[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.]

Lege Artis Medicinae

[Focus on Lege Artis Medicinae (LAM)]

VASAS Lívia, GEGES József

[Three decades ago, LAM was launched with the goal of providing scientific information about medicine and its frontiers. From the very beginning, LAM has also concerned a special subject area while connecting medicine with the world of art. In the palette of medical articles, it remained a special feature to this day. The analysis of the history of LAM to date was performed using internationally accepted publication guidelines and scientific databases as a pledge of objectivity. We examined the practice of LAM if it meets the main criteria, the professional expectations of our days, when publishing contents of the traditional printed edition and its electronic version. We explored the visibility of articles in the largest bibliographic and scientific metric databases, and reviewed the LAM's place among the Hun­ga­rian professional journals. Our results show that in recent years LAM has gained international reputation des­pite publishing in Hungarian spoken by a few people. This is due to articles with foreign co-authors as well as references to LAM in articles written exclusively by foreign researchers. The journal is of course full readable in the Hungarian bibliographic databases, and its popularity is among the leading ones. The great virtue of the journal is the wide spectrum of the authors' affiliation, with which they cover almost completely the Hungarian health care institutional sys­tem. The special feature of its columns is enhanced by the publication of writings on art, which may increase Hungarian and foreign interest like that of medical articles.]

Lege Artis Medicinae

[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.]

[Interdisciplinary approach of vestibular system impairment]

PONGRÁCZ Endre

[In the first part of this review the definition of vertigo/dizziness was discussed. The major difference between the two signs is the exsistence of the direction, which is specific for vertigo. Dizziness is a frequent complaint in the clinical practice. Its frequency is increasing with advance of age, to intimate the play of declining cognitive process in the pathogenesis of its. The popular health significance of vertigo is in the rowing number of the patients. The onset of the most cases with acute vertigo appears between secundums and minutes so the patients will be provided in circumstances of emergency department. First of all three form schould be take into account: neuronitis vestibularis, benign paroxysmal positional vertigo and Meniere syndrome. Without tipical periferal signs of vertigo, central cause should be searched, principally stroke (lysis possibility). The differential diagnose of the different dizzeness/vertigo forms according to the elapsed time of the onset or congenital and acquired nystagmus was created in tables. The recommendations of the therapy of acute and chronic dizziness/ vertigo syndroms are, lack of results of evidence based trials doubtful. The more often used drugs based on clinical trials are discussed as vinpocetine, betahistine and piracetam. The in vitro and in vivo data suggest that the last molecule is eligible to use both in periferal and central type of vertigo syndroms.]

Evaluation of anxiety, depression and marital relationships in patients with migraine

DEMIR Fıgen Ulku, BOZKURT Oya

Aim - The aim of this study was to evaluate the frequency and characteristics of attacks in patients with migraine, to determine the effects of anxiety or depressive symptoms, and to evaluate the marital relationships of patients with migraine. Method - Thirty patients who were admitted to the neurology outpatient clinic of our hospital between July 2018 and October 2018 and were diagnosed with migraine according to the 2013 International Headache Society (IHS) diagnostic criteria were included in this cross-sectional study. Age, sex, headache frequency and severity, depressive traits, marital satisfaction and anxiety status were examined. We used the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Maudsley Marital Questionnaire (MMQ) and Visual Analogue Scale (VAS) for measuring relevant parameters. Results - The mean severity of migraine pain according to VAS scale was 6.93 ± 1.41 and the mean number of migraine attacks was 4.50 ± 4.24. The mean BDI score of the patients was 12.66 ± 8.98, the mean MMQ-M score was 19.80 ± 12.52, the mean MMQ-S score was 13.20 ± 9.53, the mean STAI-state score was 39.93 ± 10.87 and the mean STAI-trait score was 45.73 ± 8.96. No significant correlation was found between age, number of migraine attacks, migraine duration, migraine headache intensity, and BDI, STAI and MMQ scores (p>0.05). But there was a positive correlation between MMQ-S and scores obtained from the BDI and STAI-state scales (p<0.05). Conclusion - In this study more than half of the migraine patients had mild, moderate or severe depression. A positive correlation was found between sexual dissatisfaction and scale scores of depression and anxiety.
