Lege Artis Medicinae - 2006;16(12)

[Hypertension is one of the most common diseases with a prevalence of over 25%. Despite of the availability of modern therapeutic options, the proportion of well-controlled patients is low. Before starting the treatment of patients with hypertension, it is essential to assess cardiovascular risk factors, co-morbidities and damages to target organs, in addition to repeated blood pressure measurements. The author first reviews the non-pharmacological treatment options of hypertension, then summarizes the most important characteristics of first-line antihypertensive agents (diuretics, beta-receptor blockers, calcium channel antagonists, angiotensin converting enzyme inhibitors, angiotensin receptor blockers). Considering the complex pathomechanism of essential hypertension, the author details the advantages and options of combined antihypertensive therapy, touching on the combinations recommended in special conditions. The metabolic effects and side-effects of antihypertensive agents, which have recently gained increased significance, are also discussed. Modern hypertension care is aimed at maximally decreasing cardiovascular morbidity and mortality, and improving the patient's quality of life. Maximum decrease of cardiovascular risk not only involves proper blood pressure control, but also aggressive fight against other risk factors (e.g., diabetes, dyslipidaemia, smoking) and treatment of target organ damages and comorbidities.]

[DISCREPANCIES BETWEEN THE CLINICAL AND PATHOLOGICAL DIAGNOSES IN CASES OF MALIGNANT TUMOUR]

KOVÁCS Attila, ILLYÉS György, SCHÖNFELD Tibor, SCHAFF Zsuzsa

[INTRODUCTION - In Hungary, like in other countries, previously undiagnosed diseases are frequently discovered at autopsies despite the availability of modern diagnostic tools. The aim of this study was to determine the accuracy of clinical diagnosis in malignant tumour cases. METHODS - Between 1996 and 2006, 5005 autopsies were performed in our institute. Malignant tumour cases with differing clinical and pathological diagnoses were selected and revised with regard to the localization of the primary tumour and the type of diagnostic difference, i.e., false negative, false positive or difference in the tumour site. The proportion of tumours with clinically undetermined primary site that were subsequently recognized at autopsy was established. The causes of misdiagnoses and the appropriateness of therapy were also analysed with regard to whether diagnostic mistakes were made and whether these significantly affected disease outcome. RESULTS - Of 1495 autopsies 235 cases (16%) showed a difference between the clinical and the pathological tumour diagnosis and a further 74 cases (5%) had a clinically undetermined primary tumour. Of the misdiagnosed cases 57% were false negative, 23% were false positive and 20% differed in their localization. Autopsy clarified 75% of the clinically undetermined primary tumours. Overall, there was one misdiagnosis or undetermined primary localization for every 5 correct clinical diagnoses (309/1495, 21%). The most frequent misdiagnosed tumours were lung, liver and kidney cancers. Most (60%) misdiagnoses were due to factors independent from the clinician, so these in fact were not diagnostic errors. Out of the remaining 40%, the true diagnostic error had an adverse effect on disease outcome in 11%.. CONCLUSION - Despite of the use of modern diagnostic tools the rate of clinically misdiagnosed malignant tumours is high, therefore, autopsy will still play an outstanding role in the future in quality control of clinical activity and education.]

[CLINICAL ASPECTS OF NOCTURNAL GASTRO-OESOPHAGEAL REFLUX]

DEMETER Pál

[Gastro-oesophageal reflux that occur at night has special clinical features and thus require extra attention. During sleep most anti-reflux mechanisms diminish, which results in prolonged contact between gastric acid and oesophageal mucosa compared to reflux during the day. Nighttime reflux symptoms adversely affect quality of life, vitality, physical and mental health. A further important consequence is the potential exacerbation of respiratory disorders such as asthma and sleep apnea. There is increasing interest in the association between nocturnal reflux and certain extra-oesophageal symptoms, including reflux laryngitis and chronic cough. An increased risk of erosive damage and adenocarcinoma of the oesophagus are also observed among patients who report nocturnal reflux symptoms. The primary goal of treatment is to improve quality of life and reduce the risk of complications by decreasing the time of acid contact with oesophageal mucosa. Nighttime reflux symptoms are much more difficult to control than daytime symptoms. Treatment guidelines generally recommend lifestyle changes as the initial approach in managing nocturnal symptoms, however, this is successful in only a small proportion of patients. Evidence-based reviews and meta-analyses favour the use of proton pump inhibitors in the treatment of gastro-oesophageal reflux disease and reflux-oesophagitis. Proton pump inhibitors are the most efficient acid-suppressing agents and thus diminish the harmful effect of acidic gastric reflux on the oesophageal mucosa. In addition, by decreasing the volume of gastric acid, they reduce the tendency to reflux.]

[Association between cyclothymic affective temperament and hypertension]

NEMCSIK János, BATTA Dóra, KŐRÖSI Beáta, RIHMER Zoltán

[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.]

[Pregnancy and cancer]

NAGY Zsuzsanna, SZILLER István, VALTINYI Dorottya, HORVÁTH Orsolya

[The joint appearance of pregnancy and cancer is rare. It is highly recommended that the tumorous pregnant should be managed by a multidisciplinary team. The early diagnosis is very important, but it is not easy, because the symptoms of pregnancy and cancer are rather similar. Imaging diagnosis has to avoid ionizing radiation (e.g. PET/CT). The same is true for chemotherapy in the fi rst trimester, due to the increased risk of developmental abnormalities. Consequently, radiation therapy is not allowded throughout the pregnancy, and the chemotherapy in the fi rst trimester is a strong indication for the interruption of pregnancy. Surgery, with good practice, usually can be performed without complications. Chemotherapy, given in the second and third trimester generally follows the standard protocols with a low frequency of developmental errors. Early delivery should not be encouraged, except the delay has a hazardous effect on the mother and/or on the child. The pregnant should be informed about all steps to be an active part of the fi nal decision.]

[POSTMENOPAUSAL HYPERTENSION]

SZÉKÁCS Béla

[Women with normal cycles on the average have lower blood pressure than age matched men. From the fifth decade of life increasing average blood pressure values of females reach or even exceed the levels of males. The frequency of hypertension among women in menopause and postmenopause is 3-4 times greater than in premenopause. This great difference can not be explained by the age dependent increase in blood pressure. There are several pathological components in the background of the elevation of blood pressure following the reduction and failure of female sex hormone production. Among these components are lifestyle changes, reduced physical activity, growing body weight, increased sympathetic activity, higher RAS (renin-angiotensin system) influence and increased salt dependence of blood pressure seem to be the dominant factors. Contrary to earlier suggestions recent clinical findings have proved that estrogen or combined hormone replacement therapy did not increase but rather slightly reduced the blood pressure in menopausal and postmenopausal hypertensive women. Therefore, hypertension itself should not be the contraindication against carefully managed hormone replacement therapy. The therapy is frequently used for preventing severe osteoporosis in spite of the disappointing cardiovascular results of the WHI and HERS trials. In the Joint National Committee 7 there are no special recommendations which would strictly prefer one or another antihypertensive agents in the pharmacological treatment of postmenopausal hypertension. However doctors are assisted in their individual therapeutical decisions by certain clinical and experimental findings which refer to higher sympathic activity, enhanced RAS influence and increased salt dependency in the pathomechanism of postmenopausal hypertension.]

[Non-HDL-cholesterol and its significance]

SIMONYI Gábor

[The role of LDL-cholesterol in cardiovascular risk has been established in a number of studies. According to current recommendations, therefore, the primary goal of lipidlowering therapy is reducing the level of LDL-cholesterol. Of lipid-lowering drugs, statins are the most efficient in reducing cardiovascular risk. According to large studies on statins, however, there is a significant residual risk even in patients receiving aggressive treatment. It is well known that many patients continue to have dyslipidaemia despite statin therapy, and not all patients with cardiovascular disease have elevated LDL-cholesterol levels. These observations indicate that lipids other than LDL-cholesterol also have a role in the development of atherosclerosis. A growing attention is paid to non-HDL-cholesterol as a cardiovascular risk factor. Calculating non-HDL-cholesterol target is easy: LDL-cholesterol measurement plus 0,8. Non-HDL-cholesterol incorporates a number of atherogenic lipoprotein particles [VLDL-cholesterol, IDL-cholesterol, LDL-cholesterol, and lipoprotein(a)]. As the atherogenic effect of apoB-containing lipoproteins (LDL, IDL-C és VLDL) is significant, they may be stronger predictors of coronary heart disease (CHD) risk than LDL-cholesterol is. Considering the strong correlation between apoB and non-HDLcholesterol and the limitations of apoB measurement (standardisation, cost), non- HDL-cholesterol is a more useful parameter and therapeutic target, especially if triglyceride levels are greater than 2.26 mmol/l.]
