Lege Artis Medicinae - 2006;16(08-09)

[Obesity, particularly intra-abdominal (visceral) obesity, is a leading cause of cardiovascular disease, insulin resistance, type 2 diabetes, dyslipidaemia, and thrombosis. There is a growing consensus that abdominal obesity, measured by wait circumference, is a better predictor of coronary artery disease, diabetes and metabolic syndrome than body mass index. Although the primary function of adipocytes is storage and release of energy, several factors secreted by adipocytes have regulatory roles in metabolism and exert vascular effects. The pro-inflammatory adipokines, for example, play a causal role in the development of insulin resistance, type 2 diabetes and cardiovascular disease. Clinical studies provide growing evidence that adipous tissue is biologically highly active and possesses a range of metabolic and endocrine functions. The aim of this review is to explore the pathophysiological connections between abdominal obesity and the development of cardiovascular diseases.]

[BRONCHUS ASSOCIATED LYMPHOID TISSUE LYMPHOMA]

HERTEL Katalin, ZSIRAY Miklós, SOLTÉSZ Ibolya

[INTRODUCTION - Primary lymphomas rarely occur in the lung. CASE REPORT - The authors present the case of an asymptomatic 61-year-old man. The patient was identified on routine chest X-ray having a streak infiltrate in the upper lobe of the right lung, which did not respond to antibiotics. On histological examination of the bronchoscopic specimen BALT- (bronchus associated lymphoid tissue) lymphoma was presumed. Since staging showed the disease to be localized, lobectomy was performed. The patient is symptom-free 16 months after surgery and there is no relapse. CONCLUSION - Although BALT-lymphomas are of low-grade malignancy in most of the cases, relapses can develop in the original organ or in other extra-nodal locations years later and BALTlymphomas may also transform into large-cell lymphomas of more aggressive behaviour.]

[RHEUMATIC DISEASES AND MALIGNANCIES - PARANEOPLASTIC SYNDROMES]

SZEKANECZ Éva, ANDRÁS Csilla, KISS Emese, TAMÁSI László, SZÁNTÓ János, SZEKANECZ Zoltán

[Numerous malignancies may be associated with musculoskeletal symptoms. In paraneoplastic syndromes, the rheumatic disease is related to the tumour development and the removal or treatment of the underlying malignancy results in the improvement of rheumatic symptoms. Sometimes it is the bad responsiveness of the rheumatic disease to conventional therapies that calls the attention to an underlying malignant condition. Therefore, in case of an unusual disease course a thorough search for malignancies is indicated. The authors give a thematic review on the most common paraneoplastic rheumatic syndromes and discuss the general diagnostic and therapeutic guidelines.]

[BREAST CANCER CARE: FROM PREVENTION TO SURVEILLANCE]

KAHÁN Zsuzsanna

[Breast cancer is the most common malignancy in women in developed countries. The development of most breast cancers is related to various hormonal effects, while 10% is associated with inherited gene mutations. Most of the primary prevention methods aim at decreasing the effects of hormones, but education on proper lifestyle is also an important risk-lowering method. The primary treatment of early breast cancer is usually breast-conserving surgery, either with the targeted removal of regional lymph nodes (by sentinel lymph node labelling) or with axillary block-dissection. The aim of postoperative radiotherapy is the eradication of the tumour cells left behind. Beside the locoregional tumour control this also plays a role in the prevention of recurrence or a secondary systemic dissemination. Adjuvant systemic treatments are used for the eradication of disseminated microscopic tumour foci. The use of modern adjuvant treatments may reduce death from the disease by up to 50%. The risks of relapse or death may be estimated based on established prognostic factors. While in low-risk patients it is not worth starting medical treatment, especially in view of the side effects, while in other cases chemo- or hormonal therapy may save the patient's life. The choice of the medical treatment should also depend on the patient's general health, the concomittant diseases and her preferences. The collaboration of the various specialists involved in the care of breast cancer patients can best take place at specialised breast centres that are equipped with the necessary technical basis, knowledge and professional experience.]

[Fructose-induced hyperuricaemia]

NAGY Judit, KISS István, WITTMANN István, KOVÁCS Tibor

[The consumption of fructose and fructose-based sweeteners has dramatically increased in the last hundred years and correlates epidemiologically with the rising prevalence of obesity, hypertension and metabolic syndrome worldwide. The administration of fructose to animals and humans increases uric acid generation independently from excessive caloric intake. Fructose ingestion may also be a risk factor of chronic kidney disease, that includes glomerular hypertension, vascular alterations (arteriolosclerosis) and albuminuria. The discovery that fructose-mediated generation of uric acid may have a casual role in metabolic syndrome and kidney disease provides new insight into pathogenesis and therapies for these important diseases.]

[THE PROBLEM OF CHILDHOOD OBESITY]

RODÉ Magdolna

[Obesity represents a major public health problem in both developed and developing countries having rapidly increased in prevalence in the past two decades. Childhood obesity is of particular concern. Two of its associated diseases require special attention; metabolic syndrome and type 2 diabetes one of its components that are increasingly diagnosed in childhood. A key to prevention and treatment is healthy lifestyle. The importance of education to healthy lifestyle from early childhood cannot be overemphasized.]

[TISSUE HORMONAL SHOCK: INTRACRINOLOGY - THE IMPORTANCE OF LOCALLY PRODUCED HORMONES IN THE PATHOGENESIS OF VARIOUS DISEASES]

SPEER Gábor, LAKATOS Péter

[This review describes the function and tissuespecific expression of the 11- and 17-beta-hydroxysteroid- dehydrogenase enzyme families as well as the aromatase and 1-alpha-hydroxylase enzymes. Recently, in situ formation of active steroids by these enzymes at the sites of their actions from biologically inactive precursors in the circulation have been demonstrated to play an important role in sex steroid-dependent neoplasms (such as breast and prostate cancer), and in some metabolic diseases (such as obesity, osteoporosis and insulin resistance). Tissuespecific Cushing syndrome (local hypercortisolism) may contribute to the pathogenesis of the latter group of diseases, suggesting that obesity may be considered the Cushing-syndrome of the omentum and that osteoporosis is the obesity of bone. Intracrinology is the science of alterations in tissue hormone synthesis catalysed by enzymes such as those mentioned above, which cannot be detected by measuring circulating hormone levels. The effects of local hormone production differ from those of the well-described autocrine, paracrine and endocrine actions. Based on the hormonal changes within various tissues, the pathogenesis of a number of diseases may be interpreted in a novel way.]

[Chronic kidney disease and atherosclerosis]

REIBER István

[Accelerated cardiovascular disease is a frequent complication of chronic kidney disease. Chronic kidney disease promotes hypertension and dyslipidaemia, which in turn can contribute to the progression of renal failure. Diabetic nephropathy is a leading cause of renal failure. Hypertension, dyslipidaemia and diabetes together are the major risk factors of the development of endothelial dysfunction and progression of atherosclerosis. Inflammatory mediators are often elevated and the renin-angiotensin system is frequently activated in chronic kidney disease. Promoters of calcification are increased and inhibitors are reduced, which favors vascular calcification, an important cause of vascular injury associated with end-stage renal disease. Accelerated atherosclerosis will then lead to increased prevalence of coronary artery disease, heart failure, stroke and peripheral arterial disease.]

[Rilmenidin - a versatile combination partner in the treatment of high blood pressure]

KÉKES Ede

[The rilmenidin as an imidazoline agonist drug strongly decreases the central sympathetic activity, release of renine and the RAS activity. Because of these advantageous properties the peripheral vascular resistance falls and the blood pressure is decreased. Today it is excellent tool for combination therapy. Useful especially in stress induced hypertension. The antihypertensive effects of ACE inhibitors sor calcium antagonists are increased by rilmenidine. This drug decreases the insuline resistance, it has a positive effect on the carbohydrate and fat metabolism, because it is useful as a complementary therapy in metabolic syndrome and diabetes mellitus of type II. It is useful in stress induced hypertension, and in menopause as well.]
