[Evaluation of bone mineral density in renal form of primary hyperparathyroidism]

CSUPOR EMŐKE, SZŰCS János, MÉSZÁROS SZILVIA, LAKATOS Péter, TÓTH EDIT, HORVÁTH CSABA

[INTRODUCTION - The most frequent manifestations of primary hyperparathyroidism are renal stones or calcipenic osteopathy. The aim of authors was to examine how bones are affected (change of bone mineral density and frequency of fractures) in the renal form of primary hyperparathyroidism. METHODS - Mean age of the patients was 57 years (26 -81 years), (4 men, 33 women). Bone mineral density was measured in the lower third of the radius, femoral neck and lumbar 2-4 vertebrae by densitometers. Moreover, occurrence of fractures and biochemical parameters characteristic for hyperparathyroidism (serum parathyroid hormone levels, calcium, phosphorus, alkaline phosphatase, urinary calcium/ creatinine) were examined. RESULTS - Bone mineral density was normal in 6 cases, osteopenic in 10 patients and 21 patients had osteoporosis. Altogether five patients had fractures. Bone mineral density and biochemical parameters were not different in patients with or without fractures. CONCLUSIONS - Bone mineral density decreases in renal form of primary hyperparathyroidism even if there is no bone disease in the clinical picture. Therefore, bone mineral density measurement is advisable for every patient with hyperparathyroidism.]

[Secondary prevention following ischemic stroke - A documentational process audit]

TÖRÖK Miklós, MIHÁLKA László, RÁCZ Sándor, FEKETE István, CSIBA László, BERECZKI Dániel

[INTRODUCTION - A previous stroke or a transient ischemic attack is an important risk factor for stroke, therefore measures for secondary prevention have great importance. Based on the results of multicenter randomized controlled trials guidelines for medical and surgical methods for secondary stroke prevention have been established in the last years. In our study - that can be considered a documentational process audit - we analyzed whether there was a change in the past 5 years in the documented recommendations for secondary stroke prevention in the discharge reports of patients with ischemic stroke. PATIENTS AND METHODS - The periods of examination were the first 3 months of 1995 and 2000. We reviewed the discharge reports of all patients discharged from the stroke unit with the diagnosis of ischemic stroke. We tabulated the history, the results of examinations, the condition of the patients at discharge, the stroke subtype, the indications and contraindications for antiplatelet and anticoagulant treatment and of carotid endarterectomy, and the recommended measure for secondary stroke prevention as documented in the discharge report. Data of 205 patients were analyzed. RESULTS - For the majority of patients medical treatment was recommended for secondary prevention. Only 5 patients were candidates for carotid endarterectomy. CONCLUSIONS - The documented practice of secondary stroke prevention significantly improved between 1995 and 2000: the recommendation of internationally accepted guidelines based on the results of randomized controlled trials are reflected better in the discharge reports of patients treated in 2000 (p = 0,0013).]

[Urinary diversion - bladder replacement]

RÉPÁSSY Dénes

[Author gives a review of the surgical procedures, advantages and disadvantages of urinary diversion and bladder replacement techniques. Orthotopic bladder replacement is presented in detail, outlining also the complications. The questions affecting general practitioners, as well as gynaecologists, surgeons and internists are also discussed at length. The different techniques of bladder replacement have become widely accepted in Hungary within the past few years. It is important therefore that all physicians involved in the care of these patients become well acquainted with the possible complications and the changes in the lifestyle of these patients.]

[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.]

[Decisional collisions between evidence and experience based medicine in care of people with epilepsy]

RAJNA Péter

[Background – Based on the literature and his long-term clinical practice the author stresses the main collisions of evidence and experience based medicine in the care of people with epilepsy. Purpose – To see, what are the professional decisions of high responsibility in the epilepsy-care, in whose the relevant clinical research is still lacking or does not give a satisfactory basis. Methods – Following the structure of the Hungarian Guideline the author points the critical situations and decisions. He explains also the causes of the dilemmas: the lack or uncertainty of evidences or the difficulty of scientific investigation of the situation. Results – There are some priorities of experience based medicine in the following areas: definition of epilepsy, classification of seizures, etiology – including genetic background –, role of precipitating and provoking factors. These are able to influence the complex diagnosis. In the pharmacotherapy the choice of the first drug and the optimal algorithm as well as the tasks during the care are also depends on personal experiences sometimes contradictory to the official recommendations. Same can occur in the choice of the non-pharmacological treatments and rehabilitation. Discussion and conclusion – Personal professional experiences (and interests of patients) must be obligatory accessories of evidence based attitude, but for achieving the optimal results, in some situations they replace the official recommendations. Therefore it is very important that the problematic patients do meet experts having necessary experiences and also professional responsibility to help in these decisions. ]

[Platelet aggregation inhibitors in the prevention of coronary coronary artery disease. „Handle with care!"]

NAGY Viktor

[Platelets play pivotal role in the pathophysiology of unstable angina, acute myocardial infarction and in complications following percutaneous coronary intervention. Three classes of platelet-inhibiting drugs, aspirin, thienopyridines and platelet glycoprotein IIb/IIIa inhibitors are now commonly used for the prevention and treatment of the disorders of coronary artery thrombosis. For the last several decades, aspirin has been the sole option for antiplatelet therapy in the treatment and prevention of the manifestations of cardiovascular disease. However, a wider selection of antiplatelet agents, including the thienopyridines (ticlopidine and clopidogrel) and the platelet glycoprotein IIb/IIIa receptor antagonists are available today. This review summarizes these drugs and scientific data that have led to their use in primary and secundary prevention, unstable angina, myocardial infarction and percutaneous coronary intervention.]

[Basics of the medical use of ayahuasca: physiology of dimethyltryptamine]

FRECSKA Ede, KOVÁCS Attila, SZABÓ Attila, FERENCZ Csaba, MÓRÉ Csaba

[Ayahuasca is a brew made of two admixture plants containing dimethyltryptamine (DMT) and b-carbolines (harmine and tetrahydroharmine). The indigenous groups of the Amazonas basin have been using it for centuries as an ethnomedical substance in healing and spiritual-religious rituals. During the last two decades the brew has raised increased scientific and public interest worldwide about its healing effects. Present paper addresses the therapeutic potentials of ayahuasca use and outlines the cellular mechanisms behind - in focus of the s-1 receptor mediated action of DMT. The scientific investigation of ayahuasca is complicated by methodical problems, legal issues, and sociocultural preconceptions.]
