[A newly discovered vasoconstrictor peptide: endothelin]

SÜTŐ Tamás, DEVECSERI Zsuzsanna, ROSIVALL László

[The discovery of endothelium-derived relaxing (prostacyclin, EDRF) and contracting factors (EDCF) in the last decade opened up new vistas in investigating the regulation of the cardiovascular system. In this review, recent results of the research of a 21 amino acid residue EDCF, called Endothelin, including its discovery, isolation, biosynthesis, tissue specific expression, receptors and the characteristics of the Endothelin converting enzyme are summarized. Based on present knowledge of the wide variety of biological actions of Endothelins, we present their possible autocrine, paracrine and humoral actions, and their significance in the physiological regulation of the cardiovascular system as well as in pathological conditions. Despite the abundance of information however, the actual role of Endothelins in the short- and long-term modulation of the tissue function still remains to be determined.]

[ATP-sensitive potassium channels, and their modulators]

FINTA P. Ervin, PETER Illes

[Recently great interest has been concentrated on potassium channels inhibited by intracellular adenosine triphosphate (ATP-sensitive potassium channels), which connect the metabolic state of cells with their electrical activity. Channel closure initiates the secretion of insulin from pancreatic ß-cells; a number of hormones altering the level of blood-sugar act via these channels. The channels are present in neurones; they regulate both in the cell bodies and the nerve terminals (e. g. peripheral nerves) the excitability. The reby, in the central nervous system, they influence the neuronal activity both in the satiety center and some catecholaminergic brain nuclei. These channels mediate the effects of endogenous vasodilators in vascular smooth muscle. They have a pathophysiological role in protecting neurones and muscle cells from hypoxic damage. The ATP-sensitive potassium channels are targets of the sulphonylurea antidiabetic agents and of a new class of drugs, the potassium channel agonists. The latter compounds are investigated or used for the treatment of hypertension, angina pectoris, cardiac insufficiency, bronchial asthma, irritable bladder syndrome, chronic occlusive arterial disease and even in impotence. They are relatively well-tolerated drugs. Their adverse effects are related to their basic vasodilator profile and most commonly include headache, dizziness, palpitation or oedema. ]

[Native CT examination of the intraarticular ligaments of the knee joint]


[The high incidence of intra-articular ligament injuries of the knee justifies a more frequent use of noninvasive diagnostic procedures such as the native CT scan. In positive cases, a correct preoperative diagnosis may be produced; a negative result is especially important, since diagnostic arthroscopy may be avoided. Due to the anatomic arrangement of the knee joint ligaments and theis density, which differentiates them from adjacent structures, an accurate, reliable, and reproducible image can be obtained with the native CT scan. With the high resolution charactaristic of the native CT scan, the ligaments of Humphry and Wrisberg can be visualized, and the two bundles of the anterior cruciate ligament can be distinguished from one another. Exact localization of intra-articular ligament rupture is essential in the planning of an optimal treatment schedule. According to the literature and the authors experience, the native CT scan is equivalent to the MRI as a diagnostic procedure in knee intra-articular ligament lesions. It has the advantage of being far less expensive and it is presently available in Hungary. ]

[Dipyridamole test: comparative evaluation of simultaneous 2D echocardiography and 201TL scintigraphy in ischaemic heart disease]

GRUBER Noémi, FORSTER Tamás, VARGA Albert, ÉDES István, CSANÁDY Miklós, MESTER János, CERNAY László

[Simultaneous 2D echocardiography and 2017 scintigraphy were performed during dipyridamole testing (DT) in 57 patients with suspected IHD. The dipyridamole dose was 0.56 mg/kg/bm in 4 minutes. If no effect was observed, the test was continued from the eighth minute with a dose of 0.28 mg/kg/bm in 2 minutes. 2D echomonitoring of the left ventricular motion using apical views was initiated at the beginning of DT and continued for 7 or 13 minutes in case of the longer test. After 6.5 or 12.5 minutes, 74 MBq 201TI was injected intravenously. Standard planar scintigraphy was performed in 3 views starting within 15 minutes. On the basis of the clinical results, 25 patients were subsequently referred for coronary angiography. The sensitivity, specificity and positive and negative predictive values of 2D echocardiography were 79%,55%,69% and 67%, respectively. The corresponding values for 201TIscintigraphy were 93%, 27%, 62%, and 75%. Where the results of both methods were positive, the combined sensitivity and specificity values were 71% and 73%. The results indicate the suitability of both methods for detecting IHD. Furthermore, they suggest a higher specificity, but lower sensitivity of 2D echocardiogaphy as compared to 201TI scintigraphy. Our observations demonstrate that the com binaton of these 2 techniques is very useful in clinical practice for the evaluation of IHD.]

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.

Evaluation of the effectiveness of transforaminal epidural steroid injection in far lateral lumbar disc herniations

EVRAN Sevket, KATAR Salim

Far lateral lumbar disc herniations (FLDH) consist approximately 0.7-12% of all lumbar disc herniations. Compared to the more common central and paramedian lumbar disc herniations, they cause more severe and persistent radicular pain due to direct compression of the nerve root and dorsal root ganglion. In patients who do not respond to conservative treatments such as medical treatment and physical therapy, and have not developed neurological deficits, it is difficult to decide on surgical treatment because of the nerve root damage and spinal instability risk due to disruption of facet joint integrity. In this study, we aimed to evaluate the effect of transforaminal epidural steroid injection (TFESI) on the improvement of both pain control and functional capacity in patients with FLDH. A total of 37 patients who had radicular pain caused by far lateral disc herniation which is visible in their lumbar magnetic resonance imaging (MRI) scan, had no neurological deficit and did not respond to conservative treatment, were included the study. TFESI was applied to patients by preganglionic approach. Pre-treatment Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores of the patients were compared with the 3rd week, 3rd month and 6th month scores after the procedure. The mean initial VAS score was 8.63 ± 0.55, while it was 3.84 ± 1.66, 5.09 ± 0.85, 4.56 ± 1.66 at the 3rd week, 3rd month and 6th month controls, respectively. This decrease in the VAS score was found statistically significant (p = 0.001). ODI score with baseline mean value of 52.38 ± 6.84 was found to be 18.56 ± 4.95 at the 3rd week, 37.41 ± 14.1 at the 3rd month and 34.88 ± 14.33 at the 6th month. This downtrend of pa­tient’s ODI scores was found statistically significant (p = 0.001). This study has demonstrated that TFESI is an effective method for gaining increased functional capacity and pain control in the treatment of patients who are not suitable for surgical treatment with radicular complaints due to far lateral lumbar disc hernia.

[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.]

[A short chronicle of three decades ]


[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.]

[Diagnosis and treatment of microvascular coronary heart disease. Specialities of conditions in Hungary]


[Invasive investigations show that in two-thirds of patients the myocardial ischaemia persists without obstructive coronary disease and any other heart conditions (INOCA). The underlying cause may be microvascular dysfunction (CMD) with consecutive microvascular coronary disease (MVD) and microvascular or epicardial vasospastic angina (MVA). The modern practice of clinical cardiology while using the developed non-invasive cardiac imaging permits exact measuring of the coronary flow with its characteristic indices. All of these improve the diagnosing of CMD-induced myocardial ischemia and provide opportunity to determine primary MVD cases. Since the recognition and treatment of MVD is significantly underrep­resented in the Hungarian medical care, the primary stable microvascular angina (MVA) is described in detail below with its modern invasive and non-invasive differential diagnosis and treatment, concerning especially its frequency provoked by high blood pressure and female coronary heart diseases. There are highlighted all recommended diagnostic procedures available under domestic conditions.]
