[Epidemiology, comorbidity, etiology of depression and cardiovascular diseases]

PÉTER László, RIHMER Zoltán

[Psychiatric problems are a common comorbid condition in patients with cardiovascular disease. Depression is a well-known risk factor for the development of cardiovascular disease and mortality too. Psychiatric and cardiovascular diseases are prevalent public health problems in the western world. Depression is associated with endo­thelial dysfunction and increased platelet aggregation, which may explain the consequent cardiovascular complications. Specific affective temperaments may be associated with special cardiovascular diseases. Antidepressant therapy does not only reduce depression but also cardiac mortality.]

[The Good, the Bad and the Ugly ]

BENCZÚR Béla, BAJNOK László, REIBER István, TSCHÜRTZ Nándor

[Reading the title most of us (but not everyone) can recall from our memories the classic heroes of the movie of Sergio Leone and we can almost hear (or not?) the melody of Ennio Morricone. This sentence is full of strangeness, isn’t it? However it’s hardly at all sure that everyone had seen the movie (indeed certainly not) and the catching music is maybe elusive. Like or not we are related to classics of lipidology, as well. Most of the readers of this review of the three clinicians know much (but not everything!) of these topics but probably for some of them this paper will arise their further interest. We are going to separate the “inseparable”, only together functioning whole thing in order to build a model in our thinking regarding its operation. This is what we do with the scientific cognition. We are making models, simplifying indeed… (sometimes erroneously) proclaiming. Let’s throw out our (or at least try to do it) the stereotypes living inside us. Let’s talk about the “always” good HDL-cholesterol, the bad LDL-cholesterol and the ugly (or cruel) triglyceride, actually (and now the analogy is lost of the three key players of the classic western movie) about the other faces of the together ugly and bad lipoprotein(a) according to a lot of opinions! As everything is connected with everything in the human body and nothing is accidental - nothing can be only good, bad or ugly nor the Good, the Bad and the Ugly yet.]

[The red eye]

IMRE László

[Eye redness may be a sign of a variety of eye diseases with different severity. Most often redness is relatively harmless, such as conjunctivitis, but it can be a serious illness with visual impairment and even lasting consequences in the background of redness. It is therefore important for non-ophthalmologists to be informed and to know the basic types of redness of the eye and to recognize typical and characteristic forms of appearance. Based on these, they can decide whether the patient can be treated or forwarded to an ophthalmic institution. In the present continuing education article we try to summarize the causes of the red eye, primarily according to the characteristics of the redness of the eye and the anatomical localization. During the investigation of a patient with red eye, the type of the redness can be determined most by diffuse illumination and by naked eye inspection without any other means. It is important to know the principal features and causes of redness of conjunctival or ciliary or scleral origin, possible other recognizable differences (e.g. conjunctival papillae or follicles or conjunctival chemosis). We have attempted to illustrate these with a number of photographs, starting with a schematic representation of the characteristic features of redness. We tried to emphasize cases suitable for treating by non-ophthalmologists and tried to draw attention to the importance of referral un­clear or complicated cases.]

[How many cardiovascular events can be avoided by a lipid lowering therapy based on preventive guidelines?]

MÁRK László

[The lipid lowering therapy became one of the most important elements in the cardiovascular prevention, yet it is not appropriately evaluated neither by the doctors, nor by the patients. The lipid goal attainment should to be improved according to Hungarian and international data. Using a recommendation guided lipid lowering therapy the most benefit can be expected in the patients at very high risk who alrea­dy had a cardiovascular event, where the LDL-cholesterol goal is 1.8 mmol/L. Calculating upon the data of 170000 patients of Cholesterol Treatment Trialists’ Collaboration a decrease of LDL-cholesterol level from 2.5 mmol/L to 1.8 in 100 patients in 10 years would avoid 3 myocardial infarctions, strokes or death, lowering that from 3.5 mmol/L to the goal would prevent these 3 events within 5 years. Using the traditional LDL-cholesterol lowering medication, high dose statin and ezetimibe, if the attitude of doctors and the compliance of patients would be ideal, the 1.8 mmol/L goal attainment rate would be over 80%. Unfortunately, up to now the reimbursed administration of ezetimibe in Hungary is still bound to a specialist’s recommendation, adding it to any dose of any statin an additional 20% LDL-cholesterol can be expected. The reimbursed administration of PCSK9-inhibitors is possible only based on a special request to National Health Insurance Fund. To achieve a better national cardiovascular morbidity and mortality the attitude of the doctors and the adherence of the patients to the lipid lowering therapy should be improved (it’s the goal of the present paper as well).]

[Gynecological correlations of eating disorders]

GALIGER-DOBOS Kitty, TÚRY Ferenc

[In recent decades, the incidence of eating disorders (its two major forms are anorexia nervosa and bulimia nervosa) has increased, their course has been delayed, and their complications are becoming more frequent and severe. Eating disorders cannot only damage physical and mental health but also affect reproductive health, future mothers and their children. Understanding the biological and psychosocial factors that explain the gynecological conditions related to eating disorders is essential regarding fertility and pregnancy. The present review summarizes data published from 2000 about the gynecological effects of eating disorders. In daily practice, the multidisciplinary collaboration is particularly important to pro­vide women with eating disorders with comprehensive care. The appropriate information of women who plan to have children is essential in order to increase the likelihood of conception and reduce the risk of miscarriage. ]

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.

[History of vaccine production in Hungary ]

ÓCSAI Lajos

[This study presents the complete history of the Hungarian vaccine production, partly in association with the process of fighting vaccine-preventable infectious diseases, and underlines the fact that every government actively contributed to the age-adjusted mandatory vaccination schedule of the past 140 years. It demonstrates the various achievements from the smallpox lymph production through the launch of diphtheria serum production at Phylaxia and the establishment of the National Public Health Institute (OKI) with its vaccine production and the later institutional transformation of OKI into Humán as economic corporation to its closure. Among all OKI’s vaccine production activities, this study focuses on the production of influenza vaccines, due to its international importance in the 1960s and 1970s. The vaccine production against diphtheria tetanus and pertussis stands out from Humán’s activities, and the tetanus component of this vaccine is still used in the products of a multinational vaccine manufacturer. ]

[Second game, 37th move and Fourth game 78th move]

VOKÓ Zoltán

[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. ]
