[Only few such outstanding physicians lived, whose achievements and personality influenced the development of the Hungarian nephrology as remarkably as professor István Taraba did. He started his university career as an experimental researcher at the Institute of Physiology on Semmelweis University, Budapest, then at the age of 34, after completing his Ph.D thesis, decided to treat patients to utilize his acquired knowledge in the field of renal failure’s pathophysiology. This way he devoted himself to cure patients with kidney failure being in very poor circumstances at that time. Besides his daily clinical activity, he accomplished outstanding organizing work in establishing and leading the Hungarian Nephrology Society, and also in initiating specialty training for nephrologists and nephrology nurses. The hallmark of his professional work was that in spite of extremely adverse circumstances he forced to improve the quality of dialysis treatment to approach European standards. Among the renal replacement treatment modalities- antecedently to his age - he respected peritoneal dialysis equal to hemodialysis, and attempted to popularize it in his country. Under his leadership the Nephrology Department of Margit Hospital in Budapest became the therapeutic and educational centre of Hungarian nephrology. His achievements have been acknowledged internationally, and his early death is substantial loss for Hungarian nephrology as a whole. It was a great honour to me to work beside him during the whole period he spent in the Margit Hospital, and since March of 1997 I have the opportunity to lead the department he had established in his intellectuality.]

[Hypertension is a global problem all over the world and also in Hungary. Although there is a wild spectrum of pharmacological and non-pharmacological antihypertensive interventions, the rate of hypertensive patients not achieving the goal blood pressure is still high. Recently developed endovascular catheterbased technology enables selective radiofrequent denervation of kidney through the lumen of renal artery. We report a case of a 52-year old hypertensive women on a combination of 11 antihypertensive medications. A successful sympathetic radiofrequent denervation was performed without complications resulting a decrease in blood pressure and medication and an increase of spontaneous baroreflex- sensitivity.]

[Hypertensive and cardiovascular risks of nonsteroidal antiinflammatory drugs]

FARSANG Csaba, BEDROS J. Róbert, ALFÖLDI Sándor

[Nonsteroidal antiinflammatory drugs (NSAIDs) are among the most frequently used medicines. During the last ten years several original publications, reviews and meta-analyses were published on the cardiovascular safety of NSAIDs and the results underlined their potentially harmful cardiovascular side effects. It can also be emphasized that there are substantial differences between different compounds, and the CV risk does not depend on the ratio of COX-1/COX-2 selectivity. Cardiovascular risk can be increased by all NSAIDs and paracetamol with the possible exception of naproxen and probably aceclofenac.]

[Etiology and diagnosis of renal failure after pediatric cardiac surgery]

TÓTH Roland, CSERÉP Zsuzsanna, SZÉKELY Andrea

[Acute kidney injury is a common and severe clinical problem in children after cardiac surgery, defined by abrupt decline in renal function, with manifestations ranging from minimal elevation of serum creatinine to anuric renal failure. The condition can have a negative influence on the long-term outcome of the illness. The problem is more likely in pediatric cardiac surgery, where the low birth-weight neonates and premature infants can be even more affected. On the other hand chronic renal disease can occur as a severe consequence of acute renal failure. The standard methods to diagnose the acute renal failure in patients are henceforward good applicable, but besides these based on the latest articles of scientific journals there are a lot of new alternatives, which could help us to establish the diagnosis of renal failure more quickly and correctly. These renal specific biomarkers and proteins could predict renal failure sensitively and specifically. Although the applicability of these methods is limited yet, there are a lot of cardiac centres for children, where they are used as routine tests.]

Creutzfeldt-Jakob Disease: A single center experience and systemic analysis of cases in Turkey

USLU Ilgen Ferda, ELIF Gökçal, GÜRSOY Esra Azize, KOLUKISA Mehmet, YILDIZ Babacan Gulsen

We aimed to analyze the clinical, laboratory and neuroimaging findings in patients with sporadic Creutzfeldt-Jakob disease (CJD) in a single center as well as to review other published cases in Turkey. Between January 1st, 2014 and June 31st, 2017, all CJD cases were evaluated based on clinical findings, differential diagnosis, the previous misdiagnosis, electroencephalography (EEG), cerebrospinal fluid and cranial magnetic resonance imaging (MRI) findings in our center. All published cases in Turkey between 2005-2018 were also reviewed. In a total of 13 patients, progressive cognitive decline was the most common presenting symptom. Two patients had a diagnosis of Heidenhain variant, 1 patient had a diagnosis of Oppenheimer-Brownell variant. Seven patients (53.3%) had been misdiagnosed with depression, vascular dementia, normal pressure hydrocephalus or encephalitis. Eleven patients (87%) had typical MRI findings but only 5 of these were present at baseline. Asymmetrical high signal abnormalities on MRI were observed in 4 patients. Five patients (45.4%) had periodic spike wave complexes on EEG, all appeared during the follow-up. There were 74 published cases in Turkey bet­ween 2005 and 2018, with various clinical presentations. CJD has a variety of clinical features in our patient series as well as in cases reported in Turkey. Although progressive cognitive decline is the most common presenting symptom, unusual manifestations in early stages of the disease might cause misdiagnosis. Variant forms should be kept in mind in patients with isolated visual or cerebellar symptoms. MRI and EEG should be repeated during follow-up period if the clinical suspicion still exists.

Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes. This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups. A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05). Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.

[Zonisamide: one of the first-line antiepileptic drugs in focal epilepsy ]

JANSZKY József, HORVÁTH Réka, KOMOLY Sámuel

[Chronic administration of antiepileptic drugs without history of unprovoked epileptic seizures are not recommended for epilepsy prophylaxis. Conversely, if the patient suffered the first unprovoked seizure, then the presence of epileptiform discharges on the EEG, focal neurological signs, and the presence of epileptogenic lesion on the MRI are risk factors for a second seizure (such as for the development of epilepsy). Without these risk factors, the chance of a second seizure is about 25-30%, while the presence of these risk factors (for example signs of previous stroke, neurotrauma, or encephalitis on the MRI) can predict >70% seizure recurrence. Thus the International League Against Epilepsy (ILAE) re-defined the term ’epilepsy’ which can be diagnosed even after the first seizure, if the risk of seizure recurrence is high. According to this definition, we can start antiepileptic drug therapy after a single unprovoked seizure. There are four antiepileptic drugs which has the highest evidence (level „A”) as first-line initial monotherapy for treating newly diagnosed epilepsy. These are: carbamazepine, phenytoin, levetiracetam, and zonisamide (ZNS). The present review focuses on the ZNS. Beacuse ZNS can be administrated once a day, it is an optimal drug for maintaining patient’s compliance and for those patients who have a high risk for developing a non-compliance (for example teenagers and young adults). Due to the low interaction potential, ZNS treatment is safe and effective in treating epilepsy of elderly people. ZNS is an ideal drug in epilepsy accompanied by obesity, because ZNS has a weight loss effect, especially in obese patients.]

Autonomic nervous system may be affected after carpal tunnel syndrome surgery: A possible mechanism for persistence of symptoms after surgery

ONDER Burcu, KELES Yavuz Betul

After carpal tunnel surgery, some patients report complaints such as edema, pain, and numbness. Purpose – The aim of this study was to evaluate autonomic nervous system function in patients with a history of carpal tunnel surgery using sympathetic skin response (SSR). Thirty three patients (55 ±10 years old) with a history of unilateral operation for carpal tunnel syndrome were included in the study. The SSR test was performed for both hands. Both upper extremities median and ulnar nerve conduction results were recorded. A reduced amplitude (p=0.006) and delayed latency (p<0.0001) were detected in the SSR test on the operated side compared to contralateral side. There was no correlation between SSR and carpal tunnel syndrome severity. Although complex regional pain syndrome does not develop in patients after carpal tunnel surgery, some of the complaints may be caused by effects on the autonomic nervous system.

[Interdisciplinary approach of vestibular system impairment]

PONGRÁCZ Endre

[In the first part of this review the definition of vertigo/dizziness was discussed. The major difference between the two signs is the exsistence of the direction, which is specific for vertigo. Dizziness is a frequent complaint in the clinical practice. Its frequency is increasing with advance of age, to intimate the play of declining cognitive process in the pathogenesis of its. The popular health significance of vertigo is in the rowing number of the patients. The onset of the most cases with acute vertigo appears between secundums and minutes so the patients will be provided in circumstances of emergency department. First of all three form schould be take into account: neuronitis vestibularis, benign paroxysmal positional vertigo and Meniere syndrome. Without tipical periferal signs of vertigo, central cause should be searched, principally stroke (lysis possibility). The differential diagnose of the different dizzeness/vertigo forms according to the elapsed time of the onset or congenital and acquired nystagmus was created in tables. The recommendations of the therapy of acute and chronic dizziness/ vertigo syndroms are, lack of results of evidence based trials doubtful. The more often used drugs based on clinical trials are discussed as vinpocetine, betahistine and piracetam. The in vitro and in vivo data suggest that the last molecule is eligible to use both in periferal and central type of vertigo syndroms.]
