[Attracted by science III. - My scientific life product of 55 years: what have I achieved?]

RADÓ János

[Author analyses the scientific results of his own clinical research work by evaluating his product in a „traditional way”, and only after then supplemented by scientometric data (citedness). From the 148 articles which has been published in foreign language (mostly in English) in abroad, 10 was grouped into the category of “new procedure/ recognition”, 40 into “original data/significant new statement”, and 98 into “new observation (statement) in a detailed question”. He has found close correlation between the values of the publications grouped by the traditional evaluation and the corresponding numbers of citations. Author discusses in the light of his own data the evaluating role of citedness with the hope to help by this motivated young scholars to plan their own future.]

[Practical questions of early diagnosis and prevention of cerebrovascular disease are highly important for all internists]

[Stroke is the third most frequent cause of death and the most important cause of disability and dependency worldwide. There are marked differences in the incidence, prevalence and mortality between the populations of Eastern and Western Europe. In Hungary, between 1998-2003, the incidence of stroke was 1,5-2 times higher than in the Western part of the continent. The early recognition of signs and symptoms of TIA and stroke and the urgent transportation of the patient to neurology, preferably to the nearest stroke-center are the key points of successful treatment, reduction of consequences and increased survival. The “time is brain” concept means that the management of TIA/stroke patients should be considered as emergency. This review briefly summarizes the epidemiology, key elements of the etiology, risk factors, up-to-dated diagnosis, primary and secondary prevention and treatment of TIA/stroke to provide information regarding the development of this field targeting the optimal management of TIA/stroke patients.]

[Cardiovascular risk caused by chronic obstructive pulmonary disease in patients with hypertension]

KISS István

[According to World Health Organization data 250 million people suffer from chronic obstructive pulmonary disease (COPD) worldwide, and the diseases accounts for 5% of total mortality. It is the only cause of death with increasing incidence and is estimated to be the third most prevalent one after stroke and myocardial infarction by 2030. In Hungary the estimated number of patients is 500 000 and projected to the number of habitants the highest number of death is caused by COPD in our country in Europe. Hypertension is a public health problem also in Hungary and it is estimated that 2.5-3.5 million adult are affected. Most of them are not aware of their disease or their treatment is insufficient. Hypertension also accounts for a great percentage of cardiovascular morbidity and mortality. Coincidence of the two diseases is significant in the adult population. According to international data the prevalence of COPD among patients with hypertension is similar to that of the general population, thus the coincidence of the two diseases may affect 2.5% of the adult population. Separate guidelines are available for the diagnosis and the treatment of the diseases, however these issues are not discussed jointly neither in international nor in Hungarian guidelines. In this review epidemiology of coincidence, the raising effect of COPD in cardiovascular risk and the potential therapeutic suggestions are summarized.]

[Cerebrovascular diseases in patients with chronic kidney disease]

KISS István, NAGY Judit

[The reason of the unfavourable life expectancy of patients with chronic kidney disease (CKD) is not only the development of end-stage renal failure but the frequent appearance of cardiovascular diseases (CVD). Chronic kidney damage itself is a cardiovascular risk state and the occurrence of CVD/associated diseases is significantly higher in chronic kidney failure. Beside risk stratification and valid treatment of CVD (hypertension, diabetes mellitus, ischemic heart disease e.g.) we and the international nephrological community have left the cerebrovascular diseases of CKD patients out of consideration. However, up to 50% of patients suffering a stroke will die immediately, only 10% of stroke survivors can continue his/her profession, but the others will be permanently disabled. High blood pressure is a strong predictor of stroke and of other CVD in most of the patients. In stroke risk reduction it is particularly important to reach the target blood pressure values. The main object of the “Live under 140/90 mmHg” programme of the Hungarian Society of Hypertension is to familiarize with target blood pressure itself and how to reach target blood pressure. In 2010, prevention, early diagnosis and management of stroke are the most important challenges of this programme (The Brain Control Programme). We think it is advisable to prepare and publish a clinical practice guideline in collaboration with stroke societies which is similar to the guidelines of international societies and of the Hungarian Society of Stroke but specific for CKD patients. This guideline would help to give a uniform, up-to-date treatment for the cerebrovascular diseases of CKD patients.]

[The beginnings and difficulties of peritoneal dialysis at the end of the last century. Part II. Hungarian experiences]

KARÁTSON András

[In Part I, I summarised the beginnings, the theoretical background and the international experiences of peritoneal dialysis. Hungarian publications related to peritoneal dialysis in the 1950s were focusing on the role of the method in the treatment of chronic renal disorders. The first dialysis centres were established in the medical universities of Hungary (Szeged in 1955, Budapest in 1960, Pécs in 1964, Debrecen in 1970) and in Miskolc in 1968. Despite the restricted hemodialysis capacities the intermittent technique of peritoneal dialysis did not spread in accordance with the demand. A survey conducted at the beginning of the 1970’s in the territory of the five counties with 1.5 million inhabitants revealed that considering the numbers of patients with renal diseases requiring dialysis, developing of a network of care and increasing the dialysis capacities is necessary and so is the development of a system of szatellite peritoneal dialysis, which was implemented with our support in 10 units of the county hospitals. A devoted and enthusiastic organiser of the nation-wide system of peritoneal dialysis was professor Taraba, who, due to his untimely death, was deprived of seeing the nation-wide spread of CAPD. At the beginning of the 1980’s the first reports on the favourable effects of CAPD appeared in Hungary. Solutions prepared in pharmacies and the lack of up-to-date equipment resulted in the frequent occurrence of peritonitis. In addition, the unfavourable memories of dialysis performed with bottled solutions (long treatment times, frequently peritonitis) were still vivid among patients and colleagues supervising the treatment. As a consequence, our survey conducted in 1991 revealed that the spread of CAPD all over the world in Hungary resulted in a significant increase of those treated with the intermittent method (more than 10% of the dialysis patients), while those treated with CAPD remained under 2%. Several reports on CAPD and the consequences that followed from them as well as the further training organised in the Szent Margit Hospital, Budapest and in Gánt, and also the guidelines issued by the Society of Hungarian Nephrologists the number of those treated with dialysis has exceeded 6000 in the past decade. 10% of them received CAPD/APD treatment.]

[The role of studies of Janos Szentagothai in developmental neurology]

[The vestibulospinal system plays determining role in the activation processes of elementary sensorymotor patterns characterised by the verticalisation of the trunk and elevation of the head. In the thirties of the last century János Szentágothai proved that axons of the vestibulospinal tract reach the cervical and thoracic spinal cord and innervate the muscles of the neck. Later he verified existence of various connections among the labyrinth, the vestibular system, and the motor nuclei of the III., IV. and the VI. cranial nerves. His studies explain the functional neuroanatomic background of sitting up, sitting and balancing in the air, head-elevation and head control during the execution of a special elementary sensorymotor pattern: ”sitting in air”. All these functions can be activated by labyrinthine stimulation long before the maturation of the corticospinal tract.]
