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.]

[STATE-OF-THE-ART DIAGNOSIS AND TREATMENT OF PITUITARY ADENOMAS SECRETING GROWTH HORMONE]

CZIRJÁK Sándor

[The history of the treatment of pituitary adenomas that cause acromegaly is as long as that of neurosurgery. While in the first half of the past century the aim of surgery was to save the patient's life, later the radical removal of the tumour was coupled with an effort to decrease complications, morbidity and mortality to the minimum. Today, beside all these, the complete sparing of the remaining hypophyseal substance and restoration of normal pituitary function are also important goals. The achievement of these goals is efficiently served by recent advances in microscopy, the minimally invasive methods of craniotomy, the availability of endoscopy in neurosurgery, three-dimensional computerguided neuronavigation, intraoperative colour Doppler sonography, as well as intraoperative real-time MRI. Recent developments in pharmacological research have created new promising conservative treatment modalities that supplement surgery, including somatostatin analogues and growth hormone receptor agonists. Also as supplementary treatment to surgery, occasionally replacing it, new radiosurgical methods, such as stereotaxic radiation, gamma knife, and heavy particle irradiation have gained grounds in neurosurgical practice.]

[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.]

[DIAGNOSIS, DIFFERENTIAL DIAGNOSIS AND TREATMENT OF HYPERPROLACTINAEMIA]

IVÁN Gabriella, GÓTH Miklós

[Hyperprolactinaemia is one of the most common endocrine diseases. Besides hypothyroidism- associated hyperprolactinaemia and that arising as a side effect of certain drugs, the most common cause of hyperprolactinaemia is a pituitary microadenoma (<10 mm in diameter) or macroadenoma (≥10 mm) that produces prolactin (prolactinoma). In addition, several physiological conditions can elevate (mostly temporarily) the serum prolactin level, therefore, setting up the precise diagnosis requires careful evaluation of the patient’s history and the laboratory, clinical, and imaging findings. Moreover, macroprolactinaemia, which is usually not a pituitary tumour-related disease, should also be ruled out. Prolactinomas represent the most common form of functioning pituitary adenomas, accounting for 30-40% of such tumours. The typical clinical symptoms of hyperprolactinaemia may be modulated by the mass effect of macroadenomas. In women the disease typically manifests as menstrual disturbance of various degree, including primary or secondary amenorrhoea, oligomenorrhoea, short luteal phase, infertility and galactorrhoea. In men reduced libido, impotence, infertility, gynaecomastia and, rarely, galactorrhoea are the typical symptoms. Dopamine agonist therapy is the first choice of treatment. Dopamine agonist therapy (bromocriptine and the recently developed quinagolide and cabergoline) successfully lowers the serum prolactine level in nearly 90% of cases, and, importantly, it also reduces the size of the tumour in the majority of cases. This explains why today surgery and radiotherapy are only used in rare special cases of prolactinoma.]

[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.]

[Recommendation for the treatment of hyperlipidemia in chronic renal disease]

MÁTYUS János, PARAGH György

[The incidence of chronic kidney disease continuously increases worldwide. Studies suggest that kidney disease is an as powerful cardiovascular risk factor as diabetes mellitus. Because of the high prevalence of lipid disorders, it is likely that dyslipidaemia plays a major role in the high cardiovascular risk of these patients. Evidence supports treating dyslipidaemia in patients with mild or moderate kidney disease, but the results of statin trials in dialysed patients are inconclusive. A practical treatment algorithm is proposed considering the special aspects, the effectiveness and safety of the drugs in the whole spectrum of kidney disease.]

[THE WORLDWIDE EPIDEMIC OF TYPE 2 DIABETES - CAUSES AND CONSEQUENCES]

JERMENDY György

[The prevalence of type 2 diabetes mellitus has recently dramatically increased worldwide. While many factors contribute to the startling data, including changes in the diagnostic criteria of glucose intolerance, increase of life expectancy, manifestation of diabetes at younger ages, and increased detection of unrecognized diabetes due to more efficient screening, the genuine, steep rise in the incidence of diabetes is explained by the increasing prevalence of obesity. Among the late complications of both diabetes and obesity, cardiovascular diseases are particularly important. Insulin resistance due to visceral obesity plays a central role in the pathomechanism of type 2 diabetes. In the prevention of both type 2 diabetes and obesity, non-pharmacological intervention such as life style changes should be considered first. Supplementary pharmacological treatment should target all cardiovascular risk factors.]

Physical activity as primary prevention of metabolic syndrome

MARTINEK Lukas, TOTHOVA Valérie, KOVAROVA Maria, DUSICKOVA Tereza, KIMMER David

Metabolic syndrome is constantly discussed, together with cancer diseases, as one of the biggest threats to the 21st century. Despite the differing indicators of specific diseases behind the metabolic syndrome, it is to be understood as a very risky aspect of health. Primary prevention through life style modifications, specifically reduction of the sedentary way of life and integration of regular physical activity into daily life of children, adults and seniors is an appropriate tool of prevention of metabolic syndrome. A number of valid studies show that increasing physical motion contributes to improvement of diseases that stand behind the metabolic syndrome. However, healthy adult population of the Czech Republic shows distinctive dislike of physical activity and primary prevention is insufficiently supported both by experts dealing with this issue and at political level while secondary prevention prevails. Therefore we consider it imperative to involve more funding into programs supporting physical activity. It is also necessary to explore forms of education within the physically active life style.

[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.]
