[The acute and chronic cardiovascular effects of sleep related breathing disorders are summarized in this review. Obstructive sleep apnoea syndrome is characterized by recurrent upper airway collapse during inspiration. The resulting asphyxia causes hypoxia and arousal. The vigorous inspiratory efforts produce falls in blood pressure coinciding with each effort (pulsus paradoxus). A rise in blood pressure is seen concurrently with each termination of apnoea and arousal. Bradycardia induced by hypoxia in each obstructive period and increased frequency at time of arousals could lead to arrhythmias. This may result in a high prevalence of hypertension, acute myocardial infarction and arrhythmias in sufferers of obstructive sleep apnoea syndrome have. ]

[Immunological aspects of granuloma formation]

DANKÓ Katalin, SZEGEDI Gyula

[The process of inflammation can be classified as acute, subacute and chronic, as well as the special category of granulomatous inflammation. Classification of granulomatous inflammation based on morphologic criteria. These are epitheloid, histiocytic, foreign-body, necrobiotic and mixed inflammatory granuloma. The current knowledge suggests the following sequences for the mechanisms of granuloma formation in sarcoidosis (Fig 2): 1. T-cells are locally activated and proliferating 2. These activated T-cells release lymphokines that recruit and activate monocytes/macrophages 3. These activated monocytes/macrophages may differentiate into granuloma cells such as epithelioids cells and multinucleated giant cells and release pro-inflammatory profibrotic mediators that modulate the granulomatous and fibrotic process. It is hoped that further studies in sarcoidosis will help not only in clarifying the pathogenic mechanisms leading to granuloma formation, but also in eventually revealing the etiology of sarcoidosis. ]

[Transvaginal ultrasound examination of embryo development in early pregnancy (sono-embryology) II. central nervous system]

CSABAY László, SZABÓ István, NÉMET János, PAPP Zoltán

[In the second part of their paper, the authors look over the most important phases of the development of the central nervous system during the first trimester of pregnancy - especially considering the stages, which can be differentiated with a high resolution transvaginal transducer. The closed neural tube is developing at days 40 to 44 by the closure of the posterior neuropore, however at this time no brain structures can be detected by ultrasound. During the 7th week the three primary brain vesicles (prosencephalon, metencepha lon, myelencephalon) can be identified – a single ventricle can be seen by ultrasound. During the 8th week the secondary brain vesicles (telencephalon, diencephalon, mesencephalon, metencephalon, myelencephalon) can be separated. During the 9th week the lateral ventricles are filled out by the choroid plexus, which are retracted to the occipital horn by the 13th week. The appearance of the brain structures also takes place according to an accurate „calendar". The structures recognized by ultrasound can be compared to those of the central nervous system known from embryology. The problem of the primary prevention of the cerebrospinal malformations, which are among the most frequent congenital disorders, is not yet solved; therefore the early prenatal diagnosis of the structural anomalies has great importance. ]

[Laparoscopic varicocelectomy]

HOLMAN Endre, TÓTH Csaba, PÁSZTOR Imre, FICSÓR Ervin, PAPP Ferenc

[ With the spreading use of the laparoscope in the urological surgery laparoscopic varicocelectomy may become an alternative treatment of varicocele. The method can be advantageous mainly for patients with bilateral cases compared to the open operation. The authors report on two cases that have been the first urological laparoscopic operations in Hungary.]

[Vascular surgical aspects of small bowel ischaemia]

DÓBI István

[A brief account is given of acute and chronic diseases underlying the disorders of blood supply to the small bowel. In cases of acute disorders, considering the diagnostic difficulties involved, the author stresses the importance of commencing of a vasodilatator treatment immediately after the tentative diagnosis has been reached based on the first suspicious symptomes, and also requiring angiography to render the accurate diagnosis. This is the only possibility to increase (without irreversible tissue damages) the number of successful early vascular reconstructions which are the prerequisites to reducing in lethality. Finally, based on his own extensive experimental work, the author proposes to make allowances for the augmented local postischaemic vasoconstrictor trends of vascular reactivity in the complex therapeutic regimen of these diseases. ]

[Evaluation of one hundered cancer cases in the practice of a general practicioner]

KISS László

[The author, working as a general practicioner in Czecho-Slovakia, gives an analysis of one hundred malignant tumour patients. In 31 cases the tumours have been in favourable position, and it would have been possible to set up early diagnosis in the general practice. The early diagnosis has actually happened only in 15 cases. The tumor has been verified at an advenced stage in 16 cases (2 of them have been inoperable). Delay has occured in two cases because of the nature of the cancer; in one case the general practicioner and in two ones the specialist missed the diagnosis; in the rest of the cases (11) the patient appeared too late. The author expresses that development in early cancer diagnosis is based on effective health education beyond the permanent on cological vigilance. ]

[Association between cyclothymic affective temperament and hypertension]


[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]


[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]

[Monitoring of the blood pressure lowering effectiveness of ramipril-amlodipine fix combination – a non-interventional trial (RAMONA study)]


[Purpose: Monitoring the effectiveness and safety of the fix combination formulation Egiramlon® therapy containing ramipril and amlodipin in patients, suffering from mild or moderate hypertension despite antihypertensive treatment. Patients and methods: Open, prospective, phase IV clinical observational study, which involved 9169 patients (age >18) with mild or moderate hypertension [TUKEB No: 16927- 1/2012/EKU (294/PI/12.)]. Ramipril/Amlodipin 5/5, 5/10, 10/5, 10/10 mg combinations were administered/ titrated in three visits, during the four months period according to the physician’s decision Blood pressure was measured by validated blood pressure sphygmomanometry and ABPM (Meditech, Hungary). The dosis of the fix combination formulation was determined individually during the visits by the 923 doctors involved in the study. The target blood pressure value was 140/90 mmHg, but in case of high risk patients population (diagnosed cardiovascular disease, diabetes), 130/90 mmHg target value was determined. Results: In 70.1% of the patients had no protocoll deviation. Patients data and examination results were processed according to this 6423 patient population. The average age of the patients were 60.2 year, in 50-50% sex distribution. The average duration of the treated hypertension was 9.8 years and the average blood pressure value was 157/91 mmHg. Till the end of the study, systolic blood pressure has decreased with 26.4 mmHg and diastolic pressure with 11.8 mmHg. An average 5.5 bpm heart rate frequency decreasing was observed at the end of the study. As a result of the treatment 52.4% of the patient population has reached the target blood pressure value.]

[Hypertension, COPD and COVID-19. Focus on antihypertensive therapy]


[Chronic obstructive pulmonary disease is a very common comorbidity of hypertension and it is often unrecognised by physicians. The factors involved in the pathomechanism of both diseases should be realised when choosing treatment. Among factors, hypoxia, increased tone of sympathetic nervous system and activation of renin-angiotensin-aldosterone system should primarily be considered. Vascular wall damage and endothelial dysfunction has an important role in both conditions. The goals of treatment are elimination of risk factors, optimizing the blood pressure, the consequential prevention of cardio-cerebrovascular, renal and pulmonary damage; finally prolonging the patients’ life and improving their quality of life as well. Both hypertension and COPD significantly worsen the condition of COVID-19 patients since they increase the severity of the disease and the rate of in-patients’ and their mortality. In the treatment of hypertension among COPD and COVID-19 patients there must be emphasized the medication inhibiting of renin-angiotensin-aldosterone system, such as angiotensin-converting en­zyme inhibitors or angiotensin-II AT1 re­cep­tor antagonists. Special attention concerned the beneficial effect of mineralocorticoid receptor antagonist spironolactone. Other antihypertensive drugs (calcium channel blockers, thiazide-like diu­retics, high selectivity β1 receptor antagonists) may supplement the treatment if necessary. Long-acting β2 receptor agonists, muscarinic receptor antagonists and inhalation corticosteroids may be administered in double or triple combination also in hypertension and COPD as well. It is important to note, that statin therapy and also vitamin D3 improve the condition of COVID-19 patients.]

[May measurement month: analysis of the Hungarian results of years 2017 and 2019]

NEMCSIK János, PÁLL Dénes, JÁRAI Zoltán

[Cardiovascular (CV) diseases are not only the leading causes of mortality in Hungary, but also the mortality rate is excessively high compared with the average of European Union, so screening programs identifying subjects with elevated blood pressure (BP) is of utmost importance. May Measurement Month (MMM) is an annual global initiative which began in 2017 aimed at raising awareness of high BP. Hungary, through the Hungarian Society of Hypertension has joined the campaign of MMM from the beginning. The results of years 2017 and 2019 are presented in this paper. ]
