DELI Gabriella, BALÁS István, KOMOLY Sámuel, DÓCZI Tamás, JANSZKY József, ASCHERMANN Zsuzsanna, NAGY Ferenc, BOSNYÁK Edit, KOVÁCS Norbert

[Background – The recently published “EarlyStim” study demonstrated that deep brain stimulation (DBS) for the treatment of Parkinson’s disease (PD) with early fluctuations is superior to the optimal pharmacological treatment in improving the quality of life and motor symptoms, and preserving sociocultural position. Our retrospective investigation aimed to evaluate if DBS therapy was able to preserve the working capabilities of our patients. Methods – We reviewed the data of 39 young (<60 years-old) PD patients who underwent subthalamic DBS implantation at University of Pécs and had at least two years follow-up. Patients were categorized into two groups based on their working capabilities: Patients with active job (“Job+” group, n=15) and retired patients (without active job, “Job-” group, n=24). Severity of motor symptoms (UPDRS part 3), quality of life (EQ-5D) and presence of active job were evaluated one and two years after the operation. Results – As far as the severity of motor symptoms were concerned, similar (approximately 50%) improvement was achieved in both groups. However, the postoperative quality of life was significantly better in the Job+ group. Majority (12/15, 80%) of Job+ group members were able to preserve their job two years after the operation. However, only a minimal portion (1/24, 4.2%) of the Job- group members was able to return to the world of active employees (p<0.01, McNemar test). Conclusion – Although our retrospective study has several limitations, our results fit well with the conclusions of “EarlyStim” study. Both of them suggest that with optimal timing of DBS implantation we may preserve the working capabilities of our patients.]

To treat or not to treat, cheyne-stokes respiration in a young adult with vascular encephalopathy

HUBATSCH Mihaela, ENGLERT Harald, WAGNER Ulrich

Cheyne-Stokes respiration (CSR) is a form of sleep-disordered breathing characterised by recurrent central sleep apnoea alternating with a crescendo-decrescendo pattern of tidal volume, relatively rare observation in sleep labs. It is mainly seen in severe heart failure and stroke. We report the case of a young man with CSR after sudden onset of seizure in the context of hypertensive exacerbation leading to the diagnosis of a leukoencephalopathy, and comment on differential diagnoses, prognostic and therapeutic outcomes. The very uniqueness of this case consists in the extremely young age for developing a vascular encephalopathy in the absence of genetic diseases and without previous diagnose of hypertension. There is no adequate explanation for the origin of vascular encephalopathy; also there is lack of evidence regarding the benefits and modality of treatment for CSR in neurologic diseases. Thus, we were forced to find the best compromise in a nocturnal oxygen therapy and follow-up.

[Novel strategy in the radiotherapy of metastatic brain tumors: simultaneous whole brain radiotherapy and integrated stereotactic radiosurgery]

KALINCSÁK Judit, LÁSZLÓ Zoltán, SEBESTYÉN Zsolt, KOVÁCS Péter, HORVÁTH Zsolt, DÓCZI Tamás, MAGNEL László

[Background and purpose – Treatment of central nervous system (CNS) tumors has always played an important role in development of radiotherapy techniques. Precise patient immobilisation, non-coplanar field arrangement, conformal treatment, arc therapy, radiosurgery, application of image fusion to radiation planning or re-irradiation were first introduced into clinical routine in the treatment of brain tumors. Methods – A modern multifunctional radiation instrument, Novalis TX has been installed at the University of Pécs two years ago. New methods, such as real time 3D image guided therapy, dynamic arc therapy and ultra-conformity offer further progress in treatment of CNS tumors. Whole brain irradiation and simultaneous fractionated stereotactic radiosurgery or integrated boost seem to be an optimal method in the treatment of not only soliter or oligo, but even a higher number (4-9) and not typically radiosensitive brain metastases. The new treatment strategy is illustrated by presentation of four case histories. Results – Treatment protocol was completed in all cases. Treatment period of 1.5 to 3 weeks, and treatment time of only a few minutes were not stressful for the patients. A quite remarkable clinical improvement as to general condition of the patients was experienced in three cases. Follow-up images confirmed either remission or a stable disease. Conclusions – Simultaneous whole brain radiotherapy and integrated stereotactic radiosurgery is a reproducible, safe method that offers an effective irradiation with delivery of definitive dosage even in cases with radio-insensitive brain metastasis.]

[The therapeutic use of transcranial magnetic stimulation in major depression]

NÉMETH Viola Luca, CSIFCSÁK Gábor, KINCSES Zsigmond Tamás, JANKA Zoltán, MUST Anita

[The antidepressive effect of repetitive transcranial magnetic stimulation (rTMS) has been investigated for almost 20 years now. Several studies have been published aiming to identify the exact and reliable parameters leading to the desired therapeutic effect. However, the related literature shows great variability. The current overview aims to provide a comprehensive overview of factors associated with the therapeutic effect of rTMS in major depression. High frequency stimulation of the left dorsolateral prefrontal cortex (DLPFC) for 3-6 weeks leads to mood improvement comparable to the effect of antidepressive medications in 35-40% of patients. Pharmacotherapy resistant patients treated with rTMS reach remission for 3 months on average. Low frequency stimulation of the right DLPFC appears to be similarly effective, though much less investigated so far. In addition to the exact delineation of the stimulation area, treatment outcome is also related to stimulation intensity as well as the number of sessions and impulses. Considering the safety and tolerability aspects of rTMS, it might be a significant therapeutic support for therapy resistant patients. Above this, patients diagnosed with major depression might benefit from the additional positive influence of rTMS improving the effect of antidepressive medication. Based on converging research evidence, the Food and Drug Administration (FDA) agency approved the use of rTMS as a treatment option for therapy resistant major depression in 2008. So far, in Hungary rTMS is primarily considered as a promising tool in research settings only. Hopefully, patients suffering from major depression will increasingly benefit from the positive therapeutic effect of this intervention.]

[Arterial hypertension and atrial fibrillation - the most important risk factors for stroke in clinical practice ]

LUDOVIT Gaspar, VESTENICKA Veronika, CAPRNDA Martin

[Vascular stroke is a very frequent cause of morbidity and mortality, and in patients who suffered stroke subsequent long-term neurological deficit of greater or lesser extent is an important factor. Numerous clinical and epidemiological studies confirmed that elevated systemic blood pressure is among the main risk factors of both ischemic and hemorrhagic vascular stroke, the effects of arterial hypertension being very complex including morphological and functional changes in vessels and vascular circulation. In our retrospective analysis of 218 patients hospitalized for stroke we found arterial hypertension in 91.2% of subjects and atrial fibrillation in 32.1% of subjects. 182 patients (83.5%) have been diagnosed with ischemic stroke and 36 patients (16.5%) with hemorrhagic stroke. In the group of patients with atrial fibrillation, only 33 patients (47.1%) were treated by anticoagulants, what points out an inadequate indication of anticoagulant treatment when considering the stroke risk calculation for atrial fibrillation (CHA2DS2- VASc Score) and bleeding risk (HAS-BLED Calculator for Atrial Fibrillation). It is also noteworthy that in the group of patients with anticoagulant therapy who have developed ischemic stroke in spite of this treatment, we found that in 48.5% the treatment was underdosed and therefore ineffective. Our work points to the need to improve the effective management of arterial hypertension and atrial fibrillation, the most common modifiable factors of vascular strokes.]

[What is worth to know about COVID-19 for (not only) a cardiologist]

HEPP Tamás, CSÉKE Balázs, BENCZÚR Béla

[SARS-CoV-2 virus infection sprang from Wuhan the capital of the Chinese Hubei province, at the end of 2019 and caused a worldwide pandemic with 1.5 million confirmed cases and claimed almost 100 000 victims until the beginning of April, 2020. First analyses of Chinese COVID-patients confirmed that diabetes, hypertension, and cardiovascular diseases were highly prevalent among SARS-CoV2 infected patients, and might be associated with poor outcome. As previously shown for SARS-CoV-1, SARS-CoV-2 similarly utilizes ACE2 as receptor for viral alveolar cell entry. A suspicion has arisen that the widely used ACE-inhibitor/ARB therapy could be potentially harmful for patients suffering from COVID-19 infection as these agents upregulate the ACE2-expressions. From the other point RAAS-blockade might be beneficial due to fact that ACE2 counters the deleterious effects of Angiotensin II. Authors provide a comprehensive over­view of the most recent literature and summarize the link between COVID-19 and car­diovascular disease. It is important to em­phasize that there are no available hu­man evidences confirming if the RAAS-in­hi­bitor therapy were harmful or helpful in pa­tients suffering from COVID-19.]

Effects of valproate, carbamazepine and levetiracetam on Tp-e interval, Tp-e/QT and Tp-e/QTc ratio

YASAR Altun, ERDOGAN Yasar

Aim - To evaluate P-wave dispersion before and after antiepileptic drug (AED) treatment as well as to investigate the risk of ventricular repolarization using the Tpeak-Tend (Tp-e) interval and Tp-e/QT ratio in patients with epileptic disorder. Methods - A total of 63 patients receiving AED therapy and 35 healthy adults were included. ECG recordings were obtained before and 3 months after anti-epileptic treatment among patients with epilepsy. For both groups, Tp-e and Tp-e/QT ratio were measured using a 12-lead ECG device. Results - Tp-e interval, Tpe/QT and Tp-e/QTc ratios were found to be higher in the patient group than in the control group (p<0.05, for all), while QTmax ratio was significantly lower in the patient group. After 3 months of AED therapy, significant increases in QT max, QTc max, QTcd, Tp-e, Tp-e/QT, and Tp-e/QTc were found among the patients (p<0.05). When the arrhythmic effects of the drugs before and after treatment were compared, especially in the valproic acid group, there were significant increases in Tp-e interval, Tp-e/QT and Tp-e/QTc values after three months of treatment (p<0.05). Carbamazepine and levetiracetam groups were not statistically significant in terms of pre- and post-treatment values. Conclusions - It was concluded that an arrhythmogenic environment may be associated with the disease, and patients who received AED monotherapy may need to be followed up more closely for arrhythmia.

[Nutritional status, realizing sarcopenia and the importance of prehabilitation in surgical departments]

CSIBA Borbála, NAGY Ákos, LUKOVICH Péter, BAROK Bianka

[INTRODUCTION - Malnutrition can significantly influence the surgery’s outcomes. Currently, patients risk grouping is based on the body mass index (BMI), and the preparation for surgery is concerned only as nut­rients administration. PATIENTS AND METHODS - The Nutrition Support Team established in our Department is assessing first the patients’ nutritional status (BMI, MUST), sarcopenia (skinfold measure, handgrip strength) and fitness status (6 min step test, sit to stand test). Risk group patients were suggested nutrients and physiotherapy prior to the surgical operation. In order to follow up our patients we created an online interface and repeated the tests immediately before the operation. RESULTS - 135 cancer patients (76 male and 59 female) were operated. Their average age was 69.6 years. 33 patients had weight loss before the first consultation (average=8.7 kg). Their average BMI was 26.3. 21 patients had gained weight in the last 6 months (average=7.8 kg). Patients with left descending colon, liver - and also pancreatic tumors had overweight BMI values while the rest of pa­tients ill with right colon and stomach neo­plasm had normal weight. Those patients who we enrolled to the online system had better results at the second assessment. CONCLUSIONS - According to our survey, most of the patients had overweight BMI values but had sarcopenia based on anthropometric tests. Therefore, the importance of in time recognized and preoperatively started nutritional therapy must be coupled with the parallel applied physiotherapy. ]

[Diagnosis and treatment of the overactive bladder]

MAJOROS Attila, ROMICS Miklós

[The Overactive Bladder Syndrome (OAB) is a symptomatic diagnosis featured mainly by urgency of urine discharging. This condition can be triggered by a number of etiological factors, most of which are idiopathic in origin. Regardless of gender and age, the prevalence is ca. 16% and has a serious impact on the quality of life of the patients. In­ves­tigations are mostly performed through usual baseline examinations; second-line invasive examinations are rarely required. The broad spectrum of treatment options ran­ges from lifestyle changes and elimina­tion of triggering factors, through be­ha­vio­ural therapy and medication to the mi­ni­mally invasive (botulinum toxin, neuro­mo­dulation, percutaneous stimulation of the tibial nerve) - and rarely - invasive thera­pies. ]
