[THE USE OF DIRECT VASODILATORS AND DIGITALIS IN CHRONIC HEART FAILURE]

DÉKÁNY Miklós

[For the optimal treatment of heart failure patients with systolic dysfunction, supplementation of the standard diuretics plus neurohormonal antagonists treatment with the direct vasodilator combination dihydralazine+nitrate, as well as with digitalis may be necessary. Addition of hydralazine/dihydralazine+nitrate to the treatment of chronic heart failure is recommended if ACE-inhibitors or angiotensin-receptor blockers cannot be administered. Beta blockers should also be used in these cases. If symptoms persist or worsen, addition of this combination to the standard therapy is reasonable. Supplementation with digitalis, mostly digoxin should be considered in similar conditions. It can be especially beneficial for patients with high-ventricular-rate atrial fibrillation. To achieve maximal survival benefit, the dose of digoxin must not exceed 0.125 mg/day. Low body weight or muscle mass, significantly reduced renal function may make further dose reduction necessary. If renal function is severely limited, digitoxin instead of digoxin may be used.]

[CARDIOLOGIC REHABILITATION IN CHRONIC HEART FAILURE]

SZÁSZ Károly

[The past decade has seen a considerable change in the approach to manage heart failure. In chronic heart failure, physical training primarily improves peripheral circulation rather than the function of the left ventricle. Regular training of patients with stable NYHA II-III stages improves physical stress tolerance and respiratory function, and also reduces the over-activated sympathetic tone. It has beneficial effects on the biochemical processes of the skeletal muscles. The duration, intensity and frequency of the training are individually set and can be changed according to the clinical state of the patient. The recommended intensity of the training is 60 to 70% of the peak oxygen use. The duration and frequency of the training depends on the clinical state of the patient and it can be raised to 3 to 6 occasions and the duration can vary between 30 to 60 minutes. For safety reasons the patient should be monitored before, during and after physical training. Cardiological rehabilitation should be a team work, with the physician as the co-ordinator, but the physiotherapist, the dietician, the psychologist and the social worker all have important, indispensable roles in achieving the optimal state of the patient.]

[RECOGNITION AND MANAGEMENT OF ACUTE HEART FAILURE]

KARLÓCAI Kristóf

[Acute heart failure may develop in previously healthy hearts. Nevertheless, structural abnormalities can facilitate its development and also, chronic heart failure can progress into acute stage. Considering the total cost of care in the patient's life, this is the most expensive heart disease. The clinical signs and physical abnormalities are usually of diagnostic power, however, instrumental investigations are necessary to recognize complications and to guide therapy. Patients should be monitored in well equipped coronary care units. Therapy consists of medications, coronary revascularization and use of mechanical assist devices.]

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.

[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.]
