MÁTÉ Orsolya, KÍVÉS Zsuzsanna, OLÁH András, FULLÉR Noémi, PAKAI Annamária

[OBJECTIVE - Since the 60’s several publications dealt with the phenomenon how physicians inform parents of newborns about postnatal recognition of Down’s syndrome and the support they receive right after breaking the bad news. Howe - ver, the rest of these studies concentrated on surveying parental satisfaction, while relatively few international studies deal with the other side of the communicational situation, the opinion of the informer. Our study focused on the circumstances of parental information in Hungarian institutions of obstetrics in order to evaluate the possibilities for interventions. METHODS - The Down’s team operating at the University of Pécs Faculty of Health Sciences carried out a national survey in 2005 - an interview-based questionnaire filled by physicians of institutions of obstetrics - with the help of the National Register for Congenital Diseases of the National Centre for Epidemiology and Down’s Foun dation. RESULTS - The coverage of the survey reached 74%. Rest of the surveyed institutions did not have information protocol, however, 70% of them believes it would be necessary. Only 44% of the physicians received communication training and 81% of them believe they can manage communication, 33% have felt that the mother of a newborn with Down’s syndrome would expect special help that the institutions are unable to provide. CONCLUSION - There are serious problems with the circumstances of parental informing in Hungarian institutions of obstetrics. This situation would obviously require intervention. An aimed communicational training based on international experience and exploiting the openness of physicians, as well as the establishment of information protocol could be elements of such intervention.]

[The prevalence of musculoskeletal symptoms among ambulance personnel in a national subsample]

PÉK Emese, BÁNFAI Bálint, DEUTSCH Krisztina, JEGES Sára, BETLEHEM József

[BACKGROUND - The ambulance workers face a lot of mental stress and physical demands in their everyday life. The physical demands can be originated from caring heavy equipment and moving patients. The poor mental health can strengthen physical problems, too. In this study our aim was to detect and compare the musculoskeletal status of ambulance personnel in two regions of Hungary. SAMPLE AND METHODS - On a voluntary base a cross-sectional anonymous, standardized self-fill-in questionnaire (Nordic Musculoskeletal Questionnaire) was used with additional items. All ambulance personnel over 18 years old were involved in the study who worked in direct patient care either in the North-Hungarian or in the West-Hungarian Region of the country. RESULTS - In the regional representative sample N=810 workers answered our questions. Out of them 587 persons (72.5%) reported about some musculoskeletal problem during his lifespan. Most of them suffered from lower back pain (448 persons, 55%), back pain (318 persons, 39%), neck pain (250 persons, 30.9%). Parallel with the aging and with the time spent working for the ambulance service more and more overall discomfort can be detected (p=0.013; p=0.020). Having a second job affected the level and frequency of discomfort negatively (p=0.005). CONCLUSIONS - More than 70% of the ambulance workers experienced musculoskeletal problem during his emergency workers carrier which may worsen the quality of his work and his personal life. To handle the situation primary prevention, screening and possibilities for recreation should be forced among ambulance workers. ]

[Recent studies have shown that adequate vitamin D level is essential in the maintenance of normal immunological status and presumably, it has a remarkable role even in the healing of some diseases. Vitamin D deficiency is a common phenomenon worldwide. Presently, the accepted marker of vitamin-D status is the total-25-hydroxy- D-vitamin [t-25(OH)D], its level depends on the specific (DBP) and aspecific (albumin) binding proteins. As known, the level of binding proteins may change in the hospitalised patients therefore, the presently used marker could not be reliable for the vitamin status in these cases. Our aim was to measure the D-vitamin supply among hospitalized patients, taking into account the level of binding proteins. METHODS - 401 cases (average age 70±14 years) were sorted from Internal Medicine (IM; 68), Intensiv Care Unit (ICU; 58), Traumatology (203 patients suffered hip fracture) and Dialysis Center (72 patients with end stage renal disease). 127 age and sex matched persons with active lifestyle served as control group. We determined t-25(OH)D, DBP, parathormon (PTHi), albumin and the albumin corrected Ca level. The bioavailable and free vitamin fractions and the free index were calculated. RESULTS - Based on the measured t- 25(OH)D, patients have more frequently suboptimal D-vitamin levels, compared to the control group (66% vs. 97%). Severe Dvitamin deficiency occured nearly 8 times more likely (6% vs. 47%) in the hospitalized patients. Chronic renal failure and malignant diseases seem to be significantly negative influencing factors in the metabolism of the vitamin D. The level of DBP, albumin, t-25(OH)D, Bio-25(OH)D was significantly lower in the patients who died. CONCLUSION - In most cases, t-25(OH)D levels show similar results about the vitamin- D supply than other calculated 25(OH)D fraction ,except for the patients of ICU and IM . The t-25(OH)D, the Bio- 25(OH)D, the DBP and the albumin levels seem to be a good prognostic marker of the outcome.]

[How can the fixed-dose atorvastatin/amlodipin combination help better adherence of patients to therapy?]

KIRÁLY Csaba, BENCZÚR Béla

[Among the main risk factors of cardiovascular disease which is the leading cause of death dyslipidemia has a great importance beyond hypertension, diabetes, smoking and obesity. These conditions rarely occure as isolated ones but very often a clustering of major CV risk factors within individual patients can be observed called metabolic syndrome. It’s a great challenge to convince asymptomatic but high-risk adults that they have to take a lot of medicine for a long time period uninterruptedly to prevent future vascular events (eg. MI or stroke) in the primary care settings. Mainly the low statin-adherence means the greatest problem particularly if a subject should take statin beside two or more drugs despite statins have the most prominent evidences in the field of cardiovascular prevention. The efficacy in improving adherence to therapy of fixed-dose atorvastatin/amlodipin combination was investigated in this paper based on the experiences of case reports derived from our clinical practice.]

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.

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.

[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.]

[What has Go to do with making clinical decisions? One of the greatest intellectual challenges of bedside medicine is making decisions under uncertainty. Besides the psychological traps of traditionally intuitive and heuristic medical decision making, lack of information, scarce resources and characteristics of doctor-patient relationship contribute equally to this uncertainty. Formal, mathematical model based analysis of decisions used widely in developing clinical guidelines and in health technology assessment provides a good tool in theoretical terms to avoid pitfalls of intuitive decision making. Nevertheless it can be hardly used in individual situations and most physicians dislike it as well. This method, however, has its own limitations, especially while tailoring individual decisions, under inclusion of potential lack of input data used for calculations, or its large imprecision, and the low capability of the current mathematical models to represent the full complexity and variability of processes in complex systems. Nevertheless, clinical decision support systems can be helpful in the individual decision making of physicians if they are well integrated in the health information systems, and do not break down the physicians’ autonomy of making decisions. Classical decision support systems are knowledge based and rely on system of rules and problem specific algorithms. They are utilized widely from health administration to image processing. The current information revolution created the so-called artificial intelligence by machine learning methods, i.e. machines can learn indeed. This new generation of artificial intelligence is not based on particular system of rules but on neuronal networks teaching themselves by huge databases and general learning algorithms. This type of artificial intelligence outperforms humans already in certain fields like chess, Go, or aerial combat. Its development is full of challenges and threats, while it presents a technological breakthrough, which cannot be stopped and will transform our world. Its development and application has already started also in the healthcare. Health professionals must participate in this development to steer it into the right direction. Lee Sedol, 18-times Go world champion retired three years after his historical defeat from AlphaGo artificial intelligence, be­cause “Even if I become the No. 1, there is an entity that cannot be defeated”. It is our great luck that we do not need to compete or defeat it, we must ensure instead that it would be safe and trustworthy, and in collaboration with humans this entity would make healthcare more effective and efficient. ]

Neuroscience highlights: The mirror inside our brain

KRABÓTH Zoltán, KÁLMÁN Bernadette

Over the second half of the 19th century, numerous theories arose concerning mechanisms involved in understanding of action, imitative learning, language development and theory of mind. These explorations gained new momentum with the discovery of the so called “mirror neurons”. Rizzolatti’s work inspired large groups of scientists seeking explanation in a new and hitherto unexplored area of how we perceive and understand the actions and intentions of others, how we learn through imitation to help our own survival, and what mechanisms have helped us to develop a unique human trait, language. Numerous studies have addressed these questions over the years, gathering information about mirror neurons themselves, their subtypes, the different brain areas involved in the mirror neuron system, their role in the above mentioned mechanisms, and the varying consequences of their dysfunction in human life. In this short review, we summarize the most important theories and discoveries that argue for the existence of the mirror neuron system, and its essential function in normal human life or some pathological conditions.
