[MENOPAUSE AND CARDIOVASCULAR RISK]

MASSZI Gabriella

[The physiological changes of menopause are associated with an increase in cardiovascular risk. Cardiovascular diseases lead mortality statistics also in women. Several physiological effects of oestrogen are thought to be protective for the circulatory system. The reasonable idea of hormone replacement therapy, however, has not met the expectations. This article reviews the relevant studies and discusses the possible causes of failure. The second part focuses on the issue of prevention. The Evidence-Based Guidelines for Cardiovascular Disease Prevention in Women, a recommendation developed in the US, is delineated. Hungarian data are provided based on results of the Menokard programme. The paper gives an overview of hormone replacement therapy and cardiovascular prevention in postmenopausal women.]

[THE PRACTICE AND RESULTS OF OSTEOPOROSIS MANAGEMENT IN HUNGARY]

POÓR Gyula

[Osteoporosis poses a major public health problem worldwide due to the extreme number of patients and to the deterioration of quality of life, disability, excess mortality and costs associated with consequent fractures. Representative studies of the author’s group have previously shown that the average bone mineral density values of the Hungarian population are among the lowest in Europe while the prevalence of vertebral fractures is among the highest in international comparison. This revelation has led to the development of a National Osteoporosis Programme, the key element of which being the setting up of a network of osteoporosis centres that are based on the collaboration of various medical specialists, the availability of advanced diagnostic tools and outstanding therapeutic opportunities. On describing the 10-year activity of the centres, the main diagnostic, prevention and management approaches of osteoporosis are discussed. According to the WHO classification the diagnosis of osteoporosis is based on a low bone mineral density finding supported by the laboratory and radiological exclusion of other metabolic bone diseases and secondary forms of osteoporosis. According to the up-to-date treatment guidelines of osteoporosis, when considering medical treatment, preference should be given to patients with high fracture risk in giving drugs with extensive antifracture efficacy that has been confirmed by studies of evidencebased medicine. Among these drugs the most important are the antiresorptive bisphosphonates that have widely been used in Hungary and the bone forming teriparatide that is expected to gain wider use in the near future with the introduction of public health insurance financing. The efficacy of these specific antiosteoporotics is increased by supplementation with calcium and vitamin D. The internationally acknowledged Hungarian osteoporosis management system offers to Hungarian patients outstanding standards for the prevention and management of osteoporosis.]

[How does the brain create rhythms?]

SZIRMAI Imre

[Connection was found between rhythmic cortical activity and motor control. The 10 Hz μ-rhythm and the 20-30 Hz bursts represent two functional states of the somatomotor system. A correspondence of the central μ-rhythm of the motor cortex and the physiological hand tremor (8-12 Hz) is presumed. The precise tuning of the motor system can be estimated by the frequency of repetitive finger movements. In complex tapping exercise, the index finger is the most skillful, the 3rd, 4th and 5th fingers keep rhythm with less precision. It was found that the organization of mirror movements depends on the cortical representation of fingers. Mirror finger movements are more regular if the subject begins the motor action with the 5th (small) finger. Concerning cortical regulation of finger movements, it was suggested that there are two time-keeping systems in the brain; one with a sensitivity above and another with a sensitivity below the critical frequency of 3 Hz. The preferred meter which helps to maintain synchronous finger movements is the cadence of 4/4 and 8/8. We observed that the unlearned inward-outward sequential finger movement was equally impaired in nonmusician controls and patients with Parkinson-disease. In movement disorders, the ability of movement and the “clock-mechanism” are equally involved. The polyrhythmic finger movement is not our inborn ability, it has to be learned. The “timer” function, which regulates the rhythmic movement, is presumably localised in the basal ganglia or in the cerebellum. The meter of the music is built on the reciprocal values of 2 raised to the second to fifth power (1/12, 1/22, 1/23, 1/24, 1/25). The EEG frequencies that we consider important in the regulation of cons-cious motor actions are approximately in the same domain (4, 8, 16, 32, 64 Hz). During music performance, an important neural process is the coupling of distant brain areas. Concerning melody, the musical taste of Europeans is octavebased. Musical ornaments also follow the rule of the gothic construction, that is: pursuit of harmony towards the single one rising from the unification of 8-4-2 classes. Leibnitz concerned music as the unconscious mathematics of the soul. Movement-initiating effect of music is used in rehabilitation of patients with movement disorders. The meter and rhythm have superiority over the melody. It is possible that rhythmic movements can be generated also in the absence of sensory input and the central oscillators can produce “fictive motor patterns”.]

[This short review will summarize some recent findings on the physiopathology of the endogenous ghrelin/obestatin system by focussing on experimental studies aiming at blocking the effects of endogenous ghrelin and clinical studies investigating genotype/phenotype correlations concerning the genes encoding for ghrelin and its cognate receptor.]

[The concept of adherence and its significance in osteoporosis]

SZEKERES László

[Today, in relation to the economical aspects of medical therapies, the patterns of patients’ drug taking have come into focus. One of the important indicators is adherence, which consists of four different concepts concerning faithfulness to therapy: acceptance, concordance, persistance and compliance. In chronic diesases, medical therapy without a certain degree of adherence is no more useful than no therapy at all. A number of international clinical studies show that in osteoporosis, the therapy can only lead to a decrease in the number of fracture in case of sufficient adherence.]
