[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.]

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.]

[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.]

[In chronic kidney disease (CKD) patients the high risk for cardiovascular events represents the major cause for morbidity and mortality. Stroke is the third most common manifestation of cardiovascular diseases and cause of death. The risk of cerebrovascular diseases persists in CKD patient in predialysis increases by 1.5-3 times whereas in patients on dialysis is increases by 4-10 times. The combination of classical cardiovascular risk factors and the pathomechanisms present in CKD and activated by dialysis treatment may explain the increased risk. The outcome of stroke is more severe in CKD, than in other populations. There are only a few data regarding early identification, primary and secondary prevention. and proper treatment of stroke in CKD patients with and without dialysis. In this review we summarize the diagnostic and treatment strategies that are based on the existing state of knowledge. However, additional studies are needed to address the poor prognosis through early identification of risk developing potential preventions and treatments of stroke in CKD.]

[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.]

Is stroke indeed a “Monday morning disease”?

FOLYOVICH András, BÉRES-MOLNÁR K Anna, GIMESI-ORSZÁGH Judit, KATONA Lajos, BICZÓ Dávid, VÖRÖS Károly, GŐBL Gábor, AJTAY András, BERECZKI Dániel

Introduction - The therapeutic time window of acute stroke is short. Decision on the use of intravenous thrombolysis is based on well-defined criteria. Any delay in the transport to a designated stroke centre decreases the odds of therapeutic success. In Hungary, the admission rate of stroke patients peaks on Monday, the number gradually decreasing by the end of the week. This phenomenon has long been suggested to be due to the lack of emergency care approach. According to the literature, however, returning to work following a holiday is a risk factor for acute stroke. A similar phenomenon is well-known in veterinary medicine, a condition in horses referred to as ‘Monday morning disease’. In our study, we analysed the distribution of admissions due to acute stroke by the day of the week in 4 independent data sources. Patients and methods - The number of patients admitted to the Szent János Hospital, Budapest, Hungary with stroke and that of emergency ambulance transports in the whole city of Budapest due to acute stroke were analysed in the period between January 1 and March 31, 2009. The distribution of thrombolytic interventions reflecting hospitalizations for hyperacute stroke was analysed based on data of the Szent János Hospital in 2009-2012, and on national data from 2006-2012. Descriptive statistics was used to present the data. The variation between daily admission was compared by chi-square test. Results - The proportion of daily admission of stroke patients admitted to the Szent János Hospital was the highest at the beginning of the week (18% on Monday, and 21% on Tuesday) and the lowest on the weekend (9% and 9% on Saturday and Sunday, respectively). The distribution of ambulance transports in Budapest due to acute stroke tended to be similar (15% and 15% on Monday and Tuesday, whereas 13% and 12% on Saturday and Sunday, respectively) on different days of the week. No such Monday peak could be observed in a single centre regarding thrombolytic interventions: 18% and 19% of the total of 80 thrombolytic interventions in the Szent János Hospital were performed on Monday and Sunday, respectively. At the national level the higher Monday rate is obvious: during a 7-year period 16.0%, 12.7%, and 13.5% of all thrombolytic interventions in Hungary were performed on Monday, Saturday and Sunday, respectively. Conclusion - Monday preference of stroke is not exclusively caused by the lack of emergency care approach, and the phenomenon is not consistent at the individual hospital level in cases undergoing thrombolysis.

[Perinatal stroke - from symptoms to follow-up]

VOJCEK Eszter, CSÉCSEI Márta, FLACH Edina, RUDAS Gábor, GRÁF Rózsa, PRINCZKEL Erzsébet

[Background and purpose - We aimed to analyze patient characteristics of term neonates with the diagnosis of stroke between 2006 and 2017 at the 3rd level Neonatal Intensive Care Unit of the Szent János Hospital. Method - We conducted a retrospective and prospective analysis including 18 newborns with stroke. Presentation, imaging methods, etiology and clinical context were discussed. All patients had a follow-up at 2 years of age or later. Subject of the study - In the past 10 years 17 term born and one premature neonate born at 36 weeks of age were diagnosed with stroke in our unit. All patients were born at good condition generally with high Apgar scores (9±1). Cesarean section was performed in 4 cases. Results - With an estimated incidence of one in 1600-4000 births, the incidence of perinatal stroke in our unit was found to be the same as mentioned in the international databeses. Regarding imaging method, cranial ultrasound scan do not visualise arterial ischaemic stroke therefore head MRI is recommended. Neurological symptoms of the patients presented in the first two days of life. Etiology included thrombophilia (4/18), infection (4/18), vascular malformation (2/18), moderate asphyxia (2/18) and pre-eclampsia (2/18). Middle cerebral artery was involved in 50% while the anterior cerebral artery was affected in 33%. The stroke occured in the left hemisphaerium in 44%, in the right side in 39% and was bilateral in 17%. In two cases the stroke was diagnosed in utero. Early childhood developmental support resulted in average or above average gross and fine motor development and cognitive outcome. Conclusion - Presenting neurological symptoms tipically occur in the first few days after birth when perinatal stroke need to be considered among the broad spectrum of neonatal illnesses. Normal developmental outcome can be achieved even in cases of extensive brain damage with early childhood developmental support. Severely impaired development was observed in the cases of in utero stroke. Inherited prothrombotic disorders may have implications for subsequent pregnancies of the mother. ]

[Despite of the symptoms of vertigo have been known since thousands of years, it was evident by the research of the pioneer scientists of the 19th century (Flourens, Ménière, Breuer and others) that dizziness can also be attributed to inner ear disfunctions. The discovery of the vestibulo-ocular reflex was an important milestone (Endre Hőgyes, 1884). The vestibulo-ocular reflex stabilizes images on the retina by rotating the eyes at the same speed but in the opposite direction of head motion. The milestone discovery of Hőgyes by stimulating individual labyrinth receptors and recording the activity of eye muscles were verified by János Szentágothai in 1950. Low-frequency lesions of the angular vestibulo-ocular reflex can be investigated by caloric test (Robert Bárány,1906), high-frequency lesions by head impulse test (Gabor Michael Halmagyi and Ian Stewart Curthoys, 1988).]

Population-based stroke screening days in the 12th district of Budapest in 2011 and 2016 - What have and what have not changed?

FOLYOVICH András, BOTOS Nóra, BALOGH Erzsébet, BAKOS Mária, HERTELENDY Anna, BÉRES-MOLNÁR Anna Katalin

Introduction - Population-based screening is an option to identify persons at high risk for stroke. However it is associated with rather high expenses, necessitating the selection of effective methods that take local characteristics into account. The 12th district of Budapest has a long tradition of population-based screening for frequent and preventable diseases. The Szent János Hospital hosts an annual stroke screening day. In the present study, previously published data from the 2011 screening were compared with those obtained in 2016, looking for changes and tendencies throughout the examined period. Subjects and methods - The screening day was conducted in a generally similar way in 2011 and 2016. Similarly to the previous event, the program was organized on a Saturday, the call for the event was spread by the local newspaper. The crew composition was the same. As regards the components of the screening (currently including general history taking, risk status assessment, blood pressure measurement, BMI assessment, cholesterol and blood glucose tests, carotid duplex ultrasonography, and ophthalmological examination), the only difference was the absence of cardiologic examination (it was conducted on an independent day). The anonymous data sheet was the same. Results - The number of participants in the 2016 event was 33, to provide more comfortable conditions. The female predominance was slightly less pronounced but was still present in 2016 (60.6% vs. 72.9%). The mean age became substantially higher (71.2 y vs. 62.9 y). The ratios of participants with higher level of education (97% vs. 94%) and those who are married were still remarkable. The most frequent risk factors were the same; however the ratio of participants with hypertension, ‘other heart disease’, and diabetes increased, whereas that of with hyperlipidemia and obesity decreased. The incidence of atrial fibrillation was unaltered. None of the participants in 2016 admitted smoking (previously this ratio was 20.8%) or drinking heavily. The findings of the carotid ultrasonography revealed a more favorable vascular status. Ophthalmological assessments (predominantly hypertensive alterations on fundoscopy) revealed that the pathological vs. physiological ratio switched to 1:2 from 2:1. The final evaluation of the screening program likewise demonstrated an improved overall state of health of the population. Conclusions - We observed a more favorable stroke risk status of the population in 2016. Whether it is indeed a tendency unknown at present. The role of the local media in calling for screening is still decisive, and the cohesive power of the family is important.
