[Frontotemporal dementia - Part I History, prevalence, clinical forms]

GALARIOTIS Vasilis, BÓDI Nikoletta, JANKA Zoltán, KÁLMÁN János

[The authors report a comprehensive publication consisting of three parts going into the details of history, prevalence, clinical forms, differential diagnosis, genetics, molecular pathomechanism, pathology, clinical diagnosis and treatment of frontotemporal dementia (FTD). The first part of the present review deals with history, prevalence and clinical forms of FTD. The prototypical FTD with circumscribed atrophy was first described by Arnold Pick; Alois Alzheimer found the intraneural inclusions in the patients’ brain. Later it was recognised that many patients had neither the atrophy nor the cellular changes, but genetic mutations have been identified. Frontotemporal dementia is a degenerative condition with unknown etiology in the frontal and anterior temporal lobes of the brain. It is a progressive neurobehavioral syndrome characterized by early decline in social interpersonal conduct, early impairment in the regulation of personal conduct, early emotional blunting, and early loss of insight. There are no reliable epidemiological studies on the prevalence of FTD, but it is well-accepted that FTD is a common cause for dementia before the age of 65 (it constitues approximately five percent of all irreversible dementias). The nomenclature of the FTD has been confusing and continues to be. Three major clinical syndromes can be identified: 1 frontal variant FTD (dementia of frontal type) in which changes in social behavior and personality predominate, 2. in semantic dementia (progressive fluent aphasia) there is a breakdown in the conceptual database which underlies language production and comprehension, 3. in progressive nonfluent aphasia the phonologic and syntactic components of language are affected. The authors report two cases, which can point to clinical symptoms and forms, and mention the problems of the differential diagnosis and therapy.]

[Introduction - The primary prevention program of the Hungarian Spine Society is set around 12 test exercises that assess performance of postural muscles and then develops their strength and flexibility. By this the scheme aims to make the biomechanically correct use of the spinal column spontaneous. Subjects and methos - The application of the scheme in the frame of physical education in a primary school was investigated in a prospective controlled study in the school-year of 2001/2002. Participating children were aged 6 to 14. The intervention group (n=200) regularly did the posture correction exercises with their teacher's direction in physical education classes, while the control group (n=213) did not. The 12 test exercises of the posture correction scheme of the Hungarian Spine Society were tested by an independent physiotherapist at the beginning and at the end of the school-year in both groups. Results were analyzed by paired and unpaired t-tests and by a chi-square test. Results - At the end of the school-year the strength and flexibility of the postural muscles of the intervention group improved significantly compared both to their own performance (p<0.01) at the beginning of the school-year and to the control group. Test results of the control group were significantly (p<0.05) worse at the end of the school-year than their own results at beginning of the school-year, and were more significantly (p<0.01) worse than the test results of intervention group. Conclusion - The results of the controlled study confirm that regular use of the preventive exercises in physical education improves the strength and flexibility of postural muscles. In order to analyze the results concerning specific muscle groups or age groups a detailed study with age- and gender-matched controls will be necessary.]

[Pathophysiology of restless leg syndrome and periodic leg movement disorder in view of the latest research findings]

KÖVES Péter, SZAKÁCS ZOLTÁN

[Both restless leg syndrome and periodic leg movement disorder have been classified as primary sleep disorders by the International Classification of Sleep Disorders. Considering the characteristic clinical symptoms, it is supposed that their pathomechanism involves the peripheral and central stimulusprocessing mechanisms of the nervous system as well as several elements of the motor system. During the last couple of years many new elements of the pathomechanism have been discovered, in particular the dysfunction of the postsynaptic dopamin receptors related to the iron metabolism of the central nervous system, the role of opiate receptors, and the involvement of subclinical small fiber neuropathy. Many of these findings have been incorporated into the diagnostic and treatment protocols used in the management of patients with restless leg syndrome or periodic leg movement disorder. Considering the rapidly increasing number of publications on their pathomechanism and the various fields it involves, the authors found it necessary to evaluate these data and to interpret their relationships within the frame of sleep-wake regulation.]

[Kidney transplantation in Hungary, 2010]

LANGER Róbert, TORONYI Éva

[Hungarian kidney transplantation has been established with three milestone operations. In 1902 Emerich Ullmann showed the technical feasibility of renal transplantation on dogs, and later the living donor transplant of András Németh in 1962 and the program starting operation of Ferenc Perner in 1973 already meant the real possibility for Hungarian patients. More than 5000 kidney transplantations were done since, and the operations are now made at the four university medical schools centers. In 2009 248 renal transplantations were done in our country (Budapest: 148, Szeged: 51, Pécs: 39, Debrecen: 34), from which 24 were living donor and nine combined kidney-pancreas cases. Despite the worsening financing situation in the health care system the numbers of transplantations are stable within a 15 year period, but this means a marked decrease in international comparison. In our country, the ratio of living donation is low, there is no paired donation, incompatible transplantation, the problems of hypersensitive patients are unresolved, and there is no old-for-old program. The solution to all of these problems could be joining to Eurotransplant, which is the definite wish of the transplant society based on the positive Slovenian and Croatian examples.]
