[Benefits of SGLT-2 inhibitors: beyond glycemic control]

BALOGH Zoltán, SIRA Lívia

[In the recent years, according to international and Hungarian guidelines, in addition to lifestyle modification, metformin is the preferred initial glucose-lowering drug for most people with type 2 diabetes, if not contraindicated. Sodium glucose co­transporter-2 inhibitors have been shown to reduce progression of chronic kidney disease, or kidney failure, as well as the risk of hospitalizations for congestive heart failure and (mainly in secondary prevention) cardiovascular death in patients with type 2 diabetes. For major adverse cardiovascular events and for the renoprotection, there seems to be no class effect. On the other hand, a class effect of sodium glucose co­transporter-2 inhibitors is evident for hospitalization for heart failure. In this review the authors summarize novel data about sodium glucose cotransporter-2 inhibitors, and about their new perspectives in the near future.]

[Tobacco use habits and cessation support tasks in Hungary. PART 1.]

CSELKÓ Zsuzsa, FÉNYES Márta, CSÁNYI Péter, BOGOS Krisztina, KISS Judit, DEMJÉN Tibor

[Today, non-communicable diseases and their underlying main risk factors, namely tobacco use, physical inactivity, excessive alcohol intake and unhealthy diet are responsible for almost 70% of the mortality worldwide. The Global Ac­tion Plan issued for the preven­tion and control of non-communicable diseases aims among others to reduce smoking rates by 30% as compared to the 2010 prevalence. The aim of the World Health Or­ga­ni­zation (WHO) in ac­cor­dance with the United Nations Sus­tai­nable Development Goals (UN SDG 2030) proposes to achieve a 23% target rate in Hun­gary by 2025. Based on the current smo­king prevalance (29%) and preliminary estimates this goal will not be accomplished. It is highly concerning that while the con­sumption of traditional tobacco products does not decrease at the expected rate in Hungary, novel nicotine and tobacco products are spreading worldwide and in Hungary as well. Thus in order to curb tobacco use, more ro­bust actions are needed in Hungary. More emphasis should be laid on the provisions of the WHO Fra­mework Con­vention on Tobacco Control (FCTC). This document re­com­mends to in­crease the tax rate of to­bacco products, declares to halt the spread of novel nicotine and tobacco products, and urges health care requirements to support smokers in quit­ting. The present summary describes the smoking cessation support related tasks of the health care in­dust­ry, taking into ac­count current national smoking habits. ]

[30 years in diabetology reflected on the pages of Lege Artis Medicinae – 1990-2020]

WINKLER Gábor

[Commemorating the 30th anniversary of foundation the journal Lege Artis Me­di­cinae, the author endeavours to review the main developments of diabetology in the same period and arranges their reflections on the journal’s pages. He points out that similar to many other disciplines, the history of development has extremely been rich in the past three decades, thus he focused only on a few issues. The author analyses the changes in the treatment of type 2 diabetes and highlights specific aspects like the importance of early metabolic control, individualized treatment choices, a risk-oriented approach instead of a glucocentric direction, and the role of patient education and a health-conscious lifestyle, which have resulted in the holistic approach of our therapeutic strategy. While using relevant quotes, the author shows that the readers of the journal were also able to keep pace with all events and they were always provided with relevant information by au­thentic specialists of diabetology. ]

[The role of intergenerational stress in the background of anorexia nervosa]

TÚRY Ferenc, PÁSZTHY bea

[In childhood and adolescence, family therapy is a crucial therapeutic method in the treatment of anorexia nervosa. Among the family stress factors there are the tensions often too obvious between the parental and grandparental generations. Three case reports are presented, where the transgenerational tensions played an important role in the family of a young patient, suffering from anorexia nervosa. During the family therapy, the treat­ment of interrelated family stress factors and focusing on transgenerational relations proved to be crucial in the successful outcomes. While treating anorexia nervosa by family therapy there are not only important the recognition and treatment of tensions within the nuclear family, but also those of stressed relations emerging from grandparental generation through multigenerational transfer mechanisms. This treatment may be successful either with the grandparent’s inclusion, or exclusion. ]

[Commemorating the Lipótmező. Part 1.]

RIHMER Zoltán

[“What did Lipótmező mean to you?” My friends and acquaintances asked frequently this question in the past decades, concerning the National Institute for Psychiatry and Neurology or well known as the Lipótmező my past workplace and the role it played in my life thus far. It is difficult to give a short answer, but the three and a half decades I have spent there were certainly of decisive importance in my professional and private life as well. Since I was banned from tobacco smoking due to my disease ten years ago, I cannot keep my pipe in my mouth any more. Thus, I decided to recollect the dearest stories kept in my memory, which had the deepest impact on me during my 35 years in Lipótmező both as a doctor and as a man. ]

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

JARABIN András János, KLIVÉNYI Péter, TISZLAVICZ László, MOLNÁR Anna Fiona, GION Katalin, FÖLDESI Imre, KISS Geza Jozsef, ROVÓ László, BELLA Zsolt

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.

[The Comprehensive Aphasia Test in Hungarian]

ZAKARIÁS Lilla, RÓZSA Sándor, LUKÁCS Ágnes

[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]

[Risk of nonsteroidal antiinflammatory drugs. Focus on aceclofenac]

FARSANG Csaba

[Nonsteroidal antiinflammatory drugs (NSAIDs) are among the most frequently used pharmaceuticals. Nevertheless, a number of studies emphasized that NSAIDs were damaging not only the gastrointestinal (GI), but also the cardiovascular (CV) system, could increase the blood pressure, the frequency of coronary events (angina, myocardial infarction) and stroke incidence, as well as they might deterio­rate renal functions. The National Institute for Health and Care Excellence (NICE) did not find evidence that administering NSAIDs could increase the risk of developing COVID-19 or worsened the condition of COVID-19 patients. However, unwanted effects of specific drugs differ substantially in their occurrence and seriousness as well. It seemed to be for a long time that the NSAIDs provoked higher GI-risk was closely related to the COX1/COX2 selectivity, like the cardiovascular (CV) risk to the COX2/COX1 selectivity, however, the recent data did not prove it clearly. Based on the available literature while pondering the gastrointestinal and cardiovascular adverse events, among all NSAIDs the aceclofenac profile seemed to be the most favourable.]

[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: 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.
