[THE VALUE OF RENAL BIOPSY IN DIABETES]

NAGY Judit, DEGRELL Péter, EKNOYAN Garabed, WITTMANN István

[The relentless increase of patients with kidney failure requiring renal replacement therapy has been documented world-wide. Recently, diabetic renal diseases has become the major cause of end-stage renal disease in the United States and in western Europe and is forecasted to become the most frequent cause of end-stage renal disease in Hungary. The most common renal lesion in type 1 as well as in type 2 diabetes is diabetic nephropathy. However, in the last few years numerous studies have demonstrated that there is a difference between patients with type 1 and those with type 2 diabetes in the expression and frequency of their renal disease. In type 1 diabetes a histological examination should only be made when a patient has features atypical of diabetic nephropathy and the indications of renal biopsy are well known. At the same time there is no agreement on renal biopsy indications in type 2 diabetes. In this review, we will summarise the characteristic features of diabetic nephropathy and other kidney alterations in the diabetic patient. Furthermore, we will raise the question of the renal biopsy indications and the more extensive use of the renal biopsy in type 2 diabetic patients for more effective prevention and treatment strategies.]

[CEREBRAL AMYLOID ANGIOPATHY - A FATAL CASE OF RECURRENT MULTIFOCAL CEREBRAL HEMORRHAGE]

POGÁNY Péter, HERMANN Zsuzsa

[Atherosclerosis and hypertension are the leading etiological factors in the pathogenesis of cerebral hemorrhage. With old age though, several other factors may appear of which cerebral amyloid angiopathy (CAA) is of major importance. This condition is characterized by the deposition of β-amyloid in the leptomeningeal vessels as well as in the small and medium sized arteries of the cerebral cortex and it is not associated with systemic amyloidosis. This pathological protein is also seen in the brains of otherwise healthy older individuals and may also appear in other diseases such as Alzheimer disease, Down-syndrome, vascular malformations, spongiform encephalopathy and dementia pugilistica. The condition may be asymptomatic but it may also cause cerebral hemorrhage, dementia or various transient neurological symptoms. Most cases are sporadic, but familial subtypes have also been described.]

[NEW DISORDERS OF EATING AND OF BODY IMAGE]

TÚRY Ferenc, LUKÁCS Liza, RÁCZ Olimpia, HORVÁTH Krisztina

[Eating disorders show an important change in the last few decades concerning their frequency and clinical picture, as well. Besides bulimia nervosa, which was described two decades ago, muscle dysmorphia appeared ten years ago as a special body image disorder of males, regarded as a reverse form of anorexia nervosa in females. Eating disorder, body builder type was described only in 2000, meaning an overconcern about the body composition and muscle mass, accompanied by strict dieting rules. Another type of these disorders was described also in 2000, the nontraditional gender role in women, which is a strong preference for male characteristics and activities, the person being comfortable with her sex, while there is no intersex condition. This overview discusses the proposed diagnostic criteria and the role of some sociocultural factors in these recent disorders.]

[EXERCISE-INDUCED BRONCHOCONSTRICTION]

VIZI Éva, CSOMA Zsuzsanna, HUSZÁR Éva

[Exercise-induced bronchoconstriction describes the transient narrowing of the airways occurring during and most often after vigorous exercise. The mechanism of exercise-induced bronchoconstriction remains elusive, although airway drying and cooling plays a prominent role. The severity of this reaction depends on the temperature and the water content of the inspired air, the type and concentration of air pollutants inspired and the intensity of the exercise. Diagnosis of exercise-induced bronchoconstriction should include baseline spirometry followed by an exercise challenge test. The exercise can be a free-running test or a laboratory based test using a cycle-ergometer or a treadmill. Pre- and post-exercise pulmonary function should be compared, 10%-15% postexercise fall in forced expiratory volume in 1 second (FEV1) is used as a diagnostic criteria (10% in laboratory test, 15% in free-running test). Heat loss, water loss, post exertional airway rewarming and the role of several mediators have been proposed as possible mechanisms responsible for the airway obstruction induced by exercise. Exercise-induced bronchoconstriction can be easily diagnosed and treated in the majority of patients. When properly treated, asthmatic individuals should be able to participate or compete in the majority of sports.]

[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. ]

[METABOLIC “X” SYNDROME: “XYNDROME” - POSITIONS AND OPPOSITIONS]

MATOS Lajos

[The idea of a constellation of abnormalities linked to insulin resistance as a key component was pioneered and summarized by Reaven in 1988 under the name of “X” syndrome. Based on the various elements of the syndrome, several synonyms have been proposed, including “deadly trio”, “deadly quartet”, “central fat syndrome”, “insulin resistance syndrome”. To avoid the confusion of this entity with “cardial X syndrome”, an established syndrome in cardiology, and instead of the rather long “metabolic X syndrome”, I have proposed the term “Xyndrome”. Irrespective of how it is called, this syndrome has come into the focus of clinical research; using the keyword “metabolic syndrome” to search in the index of the National Library of Medicine, 15.661 citations pop up, and in February 2006 only, 168 papers were published in this field. In spite of this, several international scientific organizations have recently claimed that metabolic syndrome has not been unambiguously defined, its diagnostic criteria are contradictory, and finally, the syndrome as an entity has no more value in predicting cardiovascular risk than the sum of its individual components has, therefore, the use of this notion in the clinical practice is not recommended. There are, however, opposing opinions emphasizing the importance of abdominal obesity - today considered to be most essential element -, data from recent research, and the didactic advantage that the use of this notion has improved complex treatment of its various components. It is crucial to understand that “syndrome” is not more - and not less, either - than a clustering of symptoms and findings, and should not be treated as a distinct disease. The emergence of the notion of metabolic syndrome, however, has been a step forward in the medical concept in that metabolic and cardiovascular diseases are now dealt with in a more complex way, which warrants the maintenance of this notion and the increase of our understanding by continuing research in this field.]

[Organization of rehabilitation of people with disabilities as a consequence of neurological conditions in Hungary]

FAZEKAS Gábor, DÉNES Zoltán, FÁY Veronika, URBÁN Edina, SZÉL István

[The history of rehabilitation of people with disabilities as a consequence of neurological conditions goes back to more than four decades in Hungary. The authors describe its history, how this service is organized nowadays, questions of specialization, scientific activity and quality improvement. They emphasise: any form of neurorehabilitation service (special neurorehabilitation department or programme of a multiprofile rehabilitation unit) must meet the same criteria. Quality assurance will be provided by a new accreditation system.]
