[Antiepileptic drugs in treatment of epilepsy and follow up of their efficacy]

GYIMESI Csilla, BÓNÉ Beáta, TÓTH Márton, HORVÁTH Réka, KOMOLY Sámuel, JANSZKY József

[Epilepsy is one of the most common neurological diseases usually demanding long term treatment. The prime goal of therapy is to achieve seizure freedom with avoidance of side effects. Precise diagnosis is fundamental selecting the proper antiepileptic drug(s). In addition of wide-spectrum antiepileptics, selective syndrome-specific antiepileptic drugs are available. Pharmacological features of the new antiepileptics allow more personalized clinical use. Aim of this paper is to provide a comprehensive pragmatic review of therapeutic possibilities and recommendations currently accessible in Hungary.]

[Background - Spinal cord stimulation has become an established clinical option for treatment of refractory chronic pain and angina pectoris, but its precise mechanism of action is unclear. We investigated the effect of spinal cord stimulation (SCS) on heart rate variability (HRV) and evaluating its influence on the sympathetic/parasympathetic balance in chronic pain. Materials and purpose - Seven patients (three men, four women) with SCS due to chronic pain were included. The SCS was programmed in three different ways: (i) to stimulate at an amplitude known to generate paresthesias (ON-state), (ii) at a subliminal level (SUB state), or (iii) switched off (OFFstate). HRV analysis was based on 5-min segments of the consecutive normal RR intervals and was performed with custom software (Kubios HRV Analysis). Results - The mean heart rate was higher in ON state compared to SUB state (p=0.018) and the high-frequency component of the HRV was lower in ON compared to OFF period (p=0.043). Other HRV parameters values did not significantly differ during the three tested periods. Conclusion - Spinal cord stimulation in chronic pain seems to be accompanied by reduced parasympathetic tone, unlike SCS in angina pectoris where previous studies found a reduced cardiac sympathetic tone. Our study might lead to understand the mechanism of action of SCS We investigated a relatively small number of patients, which is the main limitation of our study. Thus, further studies with larger number of patients are required for validation of our results.]

[Background and purposes - In advanced Parkinson’s disease, medically refractory motor fluctuation or medically resistant tremor considerably affects quality of life. However, these symptoms can be mostly successfully treated by deep brain stimulation. We analyzed the efficacy of bilateral subthalamic stimulation in our patients with Parkinson’s disease. Methods - We assessed the clinical data of ten patients who have been treated in the Department of Neurology, Semmelweis University and have been operated in the National Institute of Neurosciences between 2008 and 2011. The Hoehn-Yahr scale score, the Unified Parkinson’s Disease Rating Scale score and the Parkinson’s Disease Questionnaire 39, as well as the dose of antiparkinson medication were documented prior to and one year after surgery. Results - Patient condition improved according to the Hoehn-Yahr scale, approximately by two stages. The dose of antiparkinson medication could be reduced by 63.4% (p=0.005) post operation. Unified Parkinson’s Disease Rating Scale scores decreased by 70.9% (p=0.005). 12 hours after medication withdrawal, execution of daily activity improved by 57.1% (p<0.01) and motor functions developed by 79.1% (p<0.01). Duration of dyskinesias decreased by 62.5% (p=0.018), duration of akinesia diminished by 87.5% (p=0.005). Quality of life rose by 41.6% (p<0.01). Neuropsychological tests detected improvement in verbal memory. Conclusion - With deep brain stimulation, the dosage of antiparkinson medication could be significantly reduced, with considerable improvements in motor function and quality of life. Although the number of patients is still low, good results have been established by careful patient selection, precise neurosurgical procedure and by appropriate programming and patient care.]

Cyanocobalamin and cholecalciferol synergistically improve functional and histopathological nerve healing in experimental rat model

ALBAY Cem, ADANIR Oktay, AKKALP Kahraman Asli, DOGAN Burcu Vasfiye, GULAEC Akif Mehmet, BEYTEMUR Ozan

Introduction - Peripheral nerve injury (PNI) is a frequent problem among young adults. Hopefully, regeneration can occur in PNI unlike central nervous system. If nerve cut is complete, gold standard treatment is surgery, but incomplete cuts have been tried to be treated by medicines. The aim of the study was to evaluate and compare clinical and histopathological outcomes of independent treatment of each of Vitamin B12 (B12) and Vitamin D3 (D3) and their combination on sciatic nerve injury in an experimental rat model. Materials and methods - Experimental animal study was performed after the approval of BEH Ethics Committee No. 2015/10. 32 rats were grouped into four (n=8) according to treatment procedures, such as Group 1 (controls with no treatment), Group 2 (intraperitoneal 1 mg/kg/day B12), Group 3 (oral 3500 IU/kg/week D3), Group 4 (intraperitoneal 1 mg/kg/day B12+ oral 3500 IU/kg/week D3). Sciatic Functional Index (SFI) and histopathological analysis were performed. Results - SFIs of Group 2, 3, 4 were statistically significantly higher than controls. Group 2 and 3 were statistically not different, however Group 4 was statistically significantly higher than others according to SFI. Axonal degeneration (AD) in all treatment groups were statistically significantly lower than in Group 1. AD in Group 4 was significantly lower than in Group 2 and 3; there was no significant difference between Group 2 and 3. There was no significant difference between Group 1,2 and 3 in Axonolysis (A). But A of Group 4 was significantly very much lower than all others. Oedema- inflammation (OE-I) in all treatment groups were significantly lower than in Group 1; there was no significant difference between Group 2 and group 4. OE-I in Group 2 and 4 were significantly lower than in Group 3. There were no significant differences between Group 1, 2 and 3 in damage level scores; score of Group 4 was significantly lower than of Group 1. Conclusions - B12 and D3 were found effective with no statistically significant difference. But combined use of B12 and D3 improve nerve healing synergistically. We recommend combined use of B12 and D3 after PNI as soon as possible.

Introduction - Spinal Cord Injury (SCI) may often lead to significant disability in affected individuals and reduce life satisfaction. Herein we aimed to investigate the effects of the level of injury on disability and life satisfaction as well as the relation between life satisfaction and disability. Methods - Patients with at least one-year history of SCI were included. Demographic-clinical data of patients were recorded. The Craig Handicap Assessment and Reporting Technique-Short Form (CHART-SF) was used for quantifying the degree of patients’ disability. Life satisfaction was assessed by the Satisfaction with Life Scale (SWLS). Results - Of the 76 patients, 21 (27.6%) were tetraplegic and 55 (72.4%) were paraplegic. SWLS was found to be similar in tetraplegic vs. paraplegic patients (P=0.59), whereas CHART parameters such as physical independence, mobility, occupation, and total CHART value were significantly higher in paraplegic patients (P=0.04, P=0.04, P=0.001 and P=0.01, respectively). Social integration was found similarly high in both groups. There was a positive correlation between elapsed time after the injury and CHART physical independence, occupation and the level of economic sufficiency (P<0.01, P<0.01, P=0.01). Excluding the economic sufficiency (P=0.02), there was not any other association between the rest of CHART parameters and SWLS. Conclusions - According to our findings, although the level of injury seems to be influential on disability, it seems to have no significant effect on life satisfaction. Since the only thing that positively affects life satisfaction is economic sufficiency, more emphasis should be placed on regulations that increase the return to work in patients.

[Earlier and more efficiently: the role of deep brain stimulation for parkinson’s disease preserving the working capabilities]


[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.]


[The effect of intranasal salmon calcitonin therapy on bone mineral density in idiopathic male osteoporosis without vertebral fractures]


[INTRODUCTION -The aim of this study was to examine the effect of intranasal salmon calcitonin therapy on bone mineral density in idiopathic male osteoporosis without vertebral fractures. MATERIALS - The randomised, prospective, controlled trial involved 71 male patients (mean age 59±6 years) suffering from idiopathic osteoporosis (lumbal spine and femoral neck T-score <-2.5) without vertebral deformity. Study design: Treatment protocol: Patients in the control group (n=31) received 400 IU Vitamin D + 1000 mg elemental calcium daily while the treatment group (n=40) received 400 IU Vitamin D, 1000 mg elemental calcium and 200 IU calcitonin nasal spray daily, by an intermittent monthly dose. METHODS - 1. Osteodensitometry: lumbar spine (L2-4) and femoral neck were measured by dual photon absorptiometry (LUNAR DPX-L, USA), whereas non-dominant radius was measured by single photon absorptiometry (NK 364, Gamma, Hungary). 2. Roentgenomorphorphometry was done onthoracic IV to lumbar IV spines and deformity indeces were calculated. The treatment period was 18 months. Examinations were performed at baseline and at the end of treatment.The primary end-point was the change of bone density measured by osteodensitometry. Secondary end-points included the side effects of medication. RESULTS - Nasal calcitonin was associated with significant increase in bone mineral density at the lumbar spine (+3.5±4.3% vs. +0.83±6.4%, p=0.04) and the femoral neck (+3.2±3.9% vs. -0.68±5.7%, p=0.004). No significant difference was observed at the radius between the treatment groups (+1.4±8.8% vs. +1.4±10.9%, p=0.98). No osteoporotic fractures occurred in the treated group, but there were 3 fractures in the control group. Treatment was well tolerated with no premature discontinuations nor significant side effects compared to the control group. CONCLUSION - 200 IU salmon calcitonin nasal spray used daily, intermittently proved to be an effective and safe therapy in male idiopathic osteoporosis.]
