[The health care system in Hungary is financed by the social security system - from the contributions collected. Until now, this has been carried out by the OTE, a public state agency, which was split into two institutions run by local government bodies following a decision by Parliament and successful elections. Health care is now financed by the National Health Insurance Fund (OEP). ]

[The relationship between genetic polymorphism of apolipoprotein E and atherosclerosis and its relevance with clinical practice]

CSÁSZÁR Albert

[The lipoprotein metabolism, having crucial role in atherogenesis is regulated by apolipo proteins, lipoprotein receptors and lipidtrans ferase enzymes. The genetic polymorphism of these proteins has been reported to be associated with lipid disorders. Beneath the rare forms (familial hypercholesterolemia, familial defective apo B syndrome) the most important monogenetic dyslipoproteinemia seems to be related to the apolipoprotein E polymorphism. The mean serum cholesterol concentration is influenced by the different apo E phenoytpes (E4 with high, E2 with low cholesterol level). In Hungary, the allele-frequencies (22 0,06, 22 0,80, 34 0,12) and the effect of apo E alleles on cholesterol concentration are very similar to the results found in other populations. Apo E polymorphism shows association with 1. hyperlipoproteinemia type III (E 2/2); 2. dyslipoproteinemia in familial hypercholeste rolemia (E2); 3. premature coronary heart disease (E4); 4. hypercholesterolemia in some populaton (E4); 5. insulin dependent diabetes mellitus in the Hungarian population (E2); 6. the rate of intestinal cholesterol absorption in some population (E4 with higher capacity). In such conditions the determination of apo E phenotype or genotype is very important to reveal the risks of the atherosclerosis and to asses the optimal hypolipidemic therapy.]

[Transvaginal color doppler in early pregnancy]

SZABÓ István, CSABAY László, NÉMET János, PAPP Zoltán

[The authors performed serial examinations using a transvaginal transducer with color Doppler facilities in normal and pathologic early pregnancies in order to examine the circulatory changes in the female genital tract and developing embryo. This is a preliminary study demonstrating the application of TVCD and summarizing the main circulatory characteristics in early pregnancy as a part of a detailed program investigating circulation in the first trimester of pregnancy. Parallel with the implantation as a result of trophoblast induction the branches of the uterine arteries can be visualized by TVCD, and characteristic ilus velocity waveform can be identified in each portion of this network. No diastolic flow can be detected in the embryonic arteries until 12–14 weeks of gestation. The fetal heart rate shows a characteristic change between the 5th and the 14th week of gestation. Examination of the circulatory changes in pathologic early pregnancies helps to establish an exact clinical diagnosis and to choose the proper treatment. The recent advent of the transvaginal probe with color Doppler imaging has permitted accurate studies of the circulatory changes in the female reproductive organs to be performed and provided more information about physiologic and pathologic processes in early pregnancy than all the non-invasive systems developed previously. ]

[In the May issue of your newspaper, we published the musings of doctor Lajos Matos, who complained about the "pains of screening". It is feared that a supplement could be filled with not so much refuting the arguments put forward to justify his concerns, but rather adding to them. It is worth reflecting, however, at least at the level of the list, because the train of thought, which has forgotten important aspects (and facts), has led to a very depressing conclusion. ]

[Relative antithrombotic effects of aspirin and of F(ab')2 fragments of an antibody blocking glycoprotein IIB/IIIA receptor]

KISS Róbert Gábor, JEAN-MARIE Stassen, TANIA Roskams, DÉSIRÉ Collen

[The antithrombotic effect of heparin (control group, 100 U/kg bolus and 50 U/kg/hr infusion), of heparin and aspirin (ASA group, 10 mg/kg bolus) and of heparin and F(ab')2 fragments of the murine monoclonal antibody against the platelet glycoprotein lib/Illa (GPIb/Illa) receptor (7E3-F/ab'/2 group, 0.8 mg/kg bolus) were studied in 3 groups of dogs with a 3 cm long everted (inside-out) segment of the carotid artery inserted into the femoral artery and a superimposed constriction which reduced blood flow to 35% of baseline.ASA and 7E3-F(ab')2 caused inhibition of ex vivo platelet aggregation with a decrease from 63 + 8 to 16 + 10% (mean + SEM, p < 0.001) in the ASA group and from 57 £ 5 to 0% in the 7Ė3-F(ab”)2 group. The template bleeding time increased in the ASA group (from 1.4 + 0.2 to 2.9 + 0.4 min, p < 0.05) and in the 7E3-f(ab')2 group (from 1.4 + 0.2 to 51 + 12.6 min, p < 0.001). In the control group the everted segments occluded and remained closed in 6 dogs and showed cyclic flow reduction phenomena in the 5 other dogs. In the ASA group inserted arteries occluded and remained closed in 5 dogs and showed cyclic flow reduction in 4 dogs; one segment remained open (p = 0.69 compared to control). In the 7E3-F(ab')2 group all segments remained patent (p < 0.001 compared to the control and to the ASA group). Thus, the GPllb/Illa blocking monoclonal antibody is significantly more effective than aspirin in the prevention of platelet mediated arterial occlusion. ]

[Significance of intracranial lipomas in connection with a rare case ]

CSERNI Gábor

[Intracranial lipomas are rare lesions which are diagnosed in about 0,08% of autopsy cases. An intracranial lipoma in the left Sylvian area of a 93 year old woman was incidentally observed during autopsy. Histological findings supported the diagnosis based on the macroscopic characteristic features. Intracranial lipomas, which are predominantly localized in the median areas are presently considered as develop mental anomalies of the subarachnoid space and not as real tumors. The theory of their pathogenesis explains the other developmental brain anomalies that are often associated with the lesion, as well as the finding of intralipomal vessels and cranial nerves. Though such lipomas are usually asymptomatic, several cases were demonstrated to be associated with seizures. Other symptoms may include hydrocephalus, headaches, behavio ral disorders, focal neurological signs. Diagnosis is based on CT or MRI findings. Intracranial lipomas are usually treated symptomatically and surgical treatment is seldom indicated In most cases shunt operations are performed, since resection is difficult and complete relief of symptoms cannot be expected as a result. ]

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.

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

[The connection between the socioeconomic status and stroke in Budapest]

VASTAGH Ildikó, SZŐCS Ildikó, OBERFRANK Ferenc, AJTAY András, BERECZKI Dániel

[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

[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.]
